――――――――――――――――――――――――――――――――――――
【F】

【Face presentation】面先露
Baby comes into the birth canal face first.

【Factor V】凝血因子V
A protein in the blood that promotes clotting of the blood by accelerating the activation of prothrombin to thrombin. Activated factor V is inactivated by activated protein C.

【Factor V Leiden Mutation (activated protein C resistance) 】凝血因子V莱顿突变(活化蛋白C抵抗)
A genetic mutation in the factor V gene that makes the activated factor V protein resistant to inactivation by protein C. The increased activity of factor V in the blood leads to a higher risk of forming a blood clot (thrombophilia) . The factor V Leiden mutation has a prevalence of 5?% in the general population.
Factor V Leiden mutation in the mother has been associated with an increased the risk of early first trimester recurrent pregnancy loss and stillbirths.

【failure to thrive】发育不良,发育停滞
A term which refers to the slow growth and development of a baby, characterised by failure to gain weight, delayed development, unwillingness to interact, and gastrointestinal problems. Failure to thrive is almost always the result of inadequate nutrition.

【fallopian tube】输卵管
There are two fallopian tubes, one each side of the uterus, that lead from the area of the ovaries into the uterine cavity. When an ovary releases an egg, the nearest fallopian tube draws it in and transports it down to the uterus.

【False labor】假临产
Tightening of uterus without dilatation of the cervix.

【Fasting blood sugar】空腹血糖
Blood test to evaluate the amount of sugar in the blood following a time period of fasting.

【febrile convulsions】发热性惊厥,高热惊厥
spontaneous contractions and relaxations of the muscles brought about by a high temperature】

【Femur length (FL) 】股骨长度
The distance from end to end of the thigh bone (the longest bone in the body). The distance is measured by sonogram along the femur shaft (diaphysis) and should NOT include the DFE (distal femoral epiphysis) a secondary bone forming center.
To obtain the appropriate plane for measurement of the FL align the ultrasound beam perpendicular the bone.

【fertilization】受精,受胎
Conception or fertilization is the moment when sperm and egg meet, join and form a single cell. It usually takes place in the Fallopian tubes. The fertilized egg then travels into the uterus, where it implants in the lining before developing into an embryo and then a fetus.

【Fertilization age】受精龄
Dating a pregnancy from the time of fertilization. 2 weeks earlier than the gestational age.

【fertility specialist】生殖医学科专科医生
An obstetrician/gynaecologist who specialises in treating people with fertility problems.

【fetal alcohol syndrome】胎儿酒精综合症
Fetal alcohol syndrome (FAS) involves physical and mental birth defects caused by a baby's mother drinking large amounts of alcohol during pregnancy.

【Fetal anomaly】胎儿畸形
Fetal malformation or abnormal development.

【fetal distress】胎儿窘迫,胎儿宫内窘迫
Signs of fetal distress - including slowed heartbeat or absence of fetal movement - are watched for throughout labor. If a fetus's life is believed to be in danger, usually because of lack of oxygen, the immediate delivery of the baby is called for.

【Fetal fibronectin (fFN) 】胎儿纤连蛋白
Fetal fibronectin (fFN) is a glycoprotein that acts like "glue" holding the fetal sac to the uterine lining during pregnancy. It can normally be found in the cervicovaginal secretions of women up to 22 weeks of gestation. However, the presence of fetal fibronectin in cervicovaginal secretions between 24 and 34 completed weeks of gestation is reported to be associated with preterm delivery.
Pregnant women between 24 weeks, 0 days and 34 weeks, 6 days gestation with signs and symptoms of early preterm labor, intact amniotic membranes and minimal cervical dilation (<3cm) may be tested for the presence of fetal fibronectin by swabbing secretions from the posterior fornix (the vaginal area under the cervix) . The test is reported as positive or negative.
The probability that a pregnant woman will deliver prematurely after a positive test is only 40 to 60 percent. However, if the test is negative there is a 99.5 percent chance the pregnant woman will NOT deliver within seven days and a 92 percent chance that she will NOT deliver before 37 weeks. The test is, therefore, much more valuable for predicting who is unlikely to deliver.

【Fetal goiter】胎儿甲状腺肿
Enlargement of the thyroid in the fetus.

【Fetal-growth retardation (IUGR)】宫内生长迟缓
Inadequate growth of the fetus during the last stages of pregnancy.

【fetal-maternal exchange】
The transfer of oxygen and nutrients from the mother to the baby and the transfer of waste from the baby to the mother.

【fetal monitor】胎心监护器,胎儿监视器
The device used to track a fetus's heartbeat and a woman's uterine contractions during labor.

【fetal monitoring】胎儿监测
Tracking the heartbeat of a fetus and a woman's uterine contractions during labor.

【Fetal Movement】胎动
Fetal movement refers to motion of a fetus caused by its own muscle activity. Locomotor activity begins during the late embryological stage, and changes in nature throughout development. Muscles begin to move as soon as they are innervated. These first movements are not reflexive, but arise from self-generated nerve impulses originating in the spinal cord. As the nervous system matures, muscles can move in response to stimuli.
Generally speaking, fetal motility can be classified as either elicited or spontaneous, and spontaneous movements may be triggered by either the spine or the brain. Whether a movement is supraspinally determined can be inferred by comparison to movements of an anencephalic fetus.

【Fetal period】胎儿期
Time period following the embryonic period (first 10 weeks of gestation) until birth.

【fetal presentation】胎先露(最先进入骨盆入口的胎儿部
This describes the position of the baby - such as feet down (breech) or head down (vertex) - inside a woman's uterus. About 96 per cent of babies present in the vertex position; some who initially present in breech position turn before delivery begins.

【Fetal viability 】胎儿生活力
The capacity for sustained survival outside the uterus as determined by the judgment of the responsible attending physician.
The Textbook of Neonatal Resuscitation, 4th edition, advocates that no resuscitation of newborns less than 23 weeks gestational age and/or 400 g birth weight is appropriate [1]. Newborns with malformations incompatible with life such as renal agenesis, anencephaly, trisomy 13 , or trisomy 18 are not considered viable regardless of the gestational age.
1. American Academy of Pediatrics. Special considerations. In: Braner D, Kattwinkel J, Denson S, Zaichkin J, eds. Textbook of Neonatal Resuscitation. 4th ed. Elk Grove Village, IL: 2000:7-9

【Fetal Warfarin Syndrome】胎儿华法林综合征
A group of birth defects associated with exposure of the developing fetus to warfarin (Coumadin? an oral anticoagulant used to prevent blood clots. The defects include nasal hypoplasia, stippled epiphyses, limb deformities, mental retardation, and seizures. Hall et al. (1980) placed the critical period for warfarin effects on the fetus as 6 to 9 weeks following conception.
Hall JG , et al. Maternal and fetal sequelae of anticoagulation during pregnancy.Am J Med. 1980 ;68:122-40. PMID: 6985765

【fetoscopy】胎儿镜检查
In this antenatal diagnostic procedure, a doctor inserts a laparoscope (a small viewing instrument) through a small incision in a pregnant woman's abdomen and uterine wall to look for any abnormalities in the fetus. The procedure carries a 5% risk of miscarriage or premature labor.

【fetus】胎,胎儿
The name given to a growing baby after eight weeks of development; before eight weeks, the developing baby is called an embryo.

【fever】发烧,发热
Fever occurs when body temperature rises above its normal level - usually defined as 98.6 degrees F/37 degrees C, although this varies by individual and time of day. A fever is a sign of the immune system at work and usually indicates an infection.

【Fibroid (leiomyoma, myoma) 】纤维瘤(平滑肌瘤,肌瘤),子宫纤维瘤,子宫肌瘤(hysteromyoma,uterine myoma)
A non-cancerous (benign) growth of fibrous tissue and muscle fibers. Fibroids are often found in the uterus, and occur in about 30% of women over the age of 30.

【fifth disease(erythema infectiosum)】第五级疾病(传染性红斑)
Slapped cheek disease (erythema infectiosum) is also known as fifth disease because it was the last of five "red rash" childhood diseases to be defined after scarlet fever, measles, rubella, and roseola. It is characterised by fever and red cheeks.

【fine motor skills】精细动作技能,精细运动
The muscle control required to make small, precise movements, such as picking up a raisin or pushing a button.

【folic acid】叶酸
A B-complex vitamin which is essential for creating new blood cells, folic acid has been shown to reduce the incidence of neural tube defects such as spina bifida (incomplete closure of the spine) and anencephaly (partially or completely missing brain). It is recommended that all women trying to conceive should take a supplement of folic acid; good natural sources include liver, beans, and leafy green vegetables.

【follicle stimulating hormone(FSH)】促卵胞激素,促卵胞生成激素,卵胞刺激素[促性腺激素]
A hormone (a chemical) produced by the pituitary gland in the brain that stimulates the growth of eggs in the ovaries and the production of sperm in the testes.
An elevated FSH suggests partial or complete ovarian failure.

【follicles】卵泡,卵子
Each month several of these small, egg-containing cavities develop on the ovary of an ovulating woman. Each cavity contains a single immature egg; ovulation occurs when a follicle (or sometimes more than one) ruptures and releases an egg.

【fontanelle("soft spot")】囟门(婴儿头部会动的部位)
A membranous gap between the bones of the developing skull.
The newborn normally has six fontanels the anterior, posterior, two mastoid, and two sphenoid fontanels. The most prominent fontanel is the diamond-shaped anterior fontanel which is closed in 96 percent of infants by 24 months of age.
Fontanelles are soft spots on a baby's head which, during birth, enable the soft bony plates of the skull to flex, allowing the head to pass through the birth canal. Fontanelles are usually completely hardened by a child's second birthday.

【Forceps】手术钳,镊子
Instrument used to help remove baby from the birth canal during delivery.

【forceps delivery】产钳分娩,产钳助产
A delivery in which a hinged, tong-like instrument (called a forceps) is used to ease the baby's head through the birth canal.

【foreskin】(阴茎)包皮
The flap of skin which normally covers the head of the penis; it is removed when a baby is circumcised.

【formula】配方奶(母乳的替代品)
An alternative to breastmilk, the baby formulas used in bottle-feeding are usually milk-based but can also be made from soya products.

【Fragile X Syndrome (Martin-Bell syndrome)】脆[性]X综合征(Martin-Bell综合征),遗传性智力障碍的最常见的一种形式
A disorder affecting males and females characterized by mental retardation. Males , large ears and jaws, macroorchidism in males (see illustration). In the U.S. fragile X syndrome affects approximately 1 in 4000 males and 1 in 8000 females and is a common cause of autistic-like behaviors.
Fragile X syndrome is caused by an expansion mutation that prevents the normal expression of the the Fragile X mental retardation 1 (FMR1) gene located on the X chromosome.
Near the beginning of the (FMR1) gene there is normally a series of repeating nucleotide DNA bases Cytosine, Guanine, Guanine (CGG). Usually there are about 30 repeats of CGG. However some individuals have from 55 to 200 CGG repeats (the pre-mutation) which have a predilection to expand further as the gene is passed from one generation to the next through the mother. The pre-mutation does not usually expand in size when passed from father to daughter. Persons with the full mutation have more than 200 of the CGG repeats and show symptoms of fragile X syndrome.
A positive family history in a proband with developmental delay should prompt consideration of genetic testing of the FMR1 gene. The American College of Medical Genetics recommends testing for all males and females with mental retardation of unknown etiology.

【Frank breech】伸腿臀部(两腿伸直)
Baby presenting buttocks first. Legs are flexed and knees extended.

【fraternal twins(dizygotic twins)】异卵双生,异卵双胞胎(二卵双生)
Born at the same time but resulting from the fertilisation of two different eggs, fraternal twins are no more genetically similar than siblings; identical twins result from the division of one fertilised egg and are genetically identical.

【full-term】(怀孕)足月的,足月
A baby is considered full-term if born between 38 and 42 weeks' gestation.

【fundal height】宫高,子宮底高度
The distance from the top of the pubic bone to the top of the pregnant uterus (fundus) in centimeters. The measurement is used to approximate fetal age and growth.
The measurement in centimeters gives an estimate of the gestational age in weeks from 16 to 38 weeks (+/- 3 centimeters). The measurement may not coincide with the gestational age if there is a growth disturbance , large fibroids, or abnormalities of the amniotic fluid.

【fundus】基底,宫底
The upper, rounded portion of the uterus.

【gamete intra-fallopian transfer】配子输卵管内移植,输卵管内配子转移技术
GIFT is an assisted conception treatment similar to IVF which involves removing eggs from a woman's ovaries, mixing them with sperm, and transferring them to the Fallopian tubes, allowing fertilisation to take place within the woman's body.

【Gastroschisis】腹裂(畸形)
An opening beside the umbilical cord that allows bowel to protrude outside of the abdomen. Gastroschisis is thought to arise from disruption of blood flow to the affected abdominal wall.
Gastroschisis occurs with an incidence of 1:10,000 births, and for unclear reasons is seen more frequently in younger mothers. The defect is also seen more frequently in mothers who use vasoactive substances such as nicotine and cocaine. The recurrence risk of 3% to 5% suggests a complex mode of inheritance. Cases of a familial pattern of inheritance have been reported.
Although gastroschisis is not associated with an increased rate of chromosomal abnormalities intestinal malrotation, atresia, volvulus, and infarction may complicate the condition. The prognosis is generally favorable with survival rates between 77% and 100% Gastroschisis is associated with intrauterine fetal growth restriction , preterm delivery, and stillbirth .

【gene therapy】基因治疗
An experimental procedure to treat genetic disorders by inserting healthy genes into the body to replace damaged ones.

【General Practitioner】(医院以外的)全科医生,普通医生
A doctor who treats patients of all ages and either sex and can care for the whole family.

【genetic counseling】遗传咨询
This form of counseling helps prospective parents to evaluate their risks of having a child with congenital abnormalities, and to understand their options for testing and treatment.

【genetic disorder】遗传紊乱,遗传病
A disease or condition which originates in the genes.

【genetic inheritance】遗传的遗传
The DNA that is passed from parents to children.

【genetic screening】遗传病筛查
Any test used to find genetic abnormalities.

【Genital herpes simplex】生殖器单纯疱疹
Herpes simplex infection involving the genital area. It can be significant during pregnancy because of the danger to a newborn fetus infected with herpes simplex.

【genitals】生殖器(尤指男性外生殖器)
The external sex organs: the penis and testicles in a male and the labia in a female.

【Genitourinary problems】泌尿生殖疾病
Defects or problems involving genital organs and the bladder or kidneys.

【gestation】妊娠,怀孕

【Gestational diabetes】妊娠糖尿病
Occurrence or worsening of diabetes during pregnancy (gestation).

【gestational diabetes mellitus(GDM)】妊娠糖尿病,妊娠合并糖尿病
Carbohydrate intolerance with onset or first recognition during pregnancy.
A fasting plasma glucose level >126 mg/dl (7.0 mmol/l) or a casual plasma glucose >200 mg/dl (11.1 mmol/l) meets the threshold for the diagnosis of diabetes, if confirmed on a subsequent day, and precludes the need for any glucose challenge. In the absence of this degree of hyperglycemia patients may be evaluated using a 1 hour 50 gram oral glucose tolerance test (OGTT) as screening test, or proceed directly to a diagnostic 3 hour 100 gram OGTT.
Gestational diabetes increases the risk of maternal hypertensive disorders, cesarean delivery, fetal macrosomia, neonatal hypoglycemia, jaundice, polycythemia, and hypocalcemia. In addition, fasting hyperglycemia may be associated with an increase in the risk of intrauterine fetal death during the last 4? weeks of gestation.

【Gestational trophoblastic disease (GTN)】妊娠性滋养层细胞病
Abnormal pregnancy with cystic growth of the placenta. Characterized by bleeding during early and middle pregnancy.

【glandular fever】腺热,传染性单核白细胞增多

【glue ear】(儿童的)咽鼓管堵塞,胶耳
This is often the result of an ear infection, where fluid is left in the middle ear. It can lead to partial deafness. If it doesn't clear by itself, a child might be advised to have grommets fitted. These are tiny tubes which help to clear the fluid.

【gluten-sensitive enteropathy】麸胶敏感性肠病
Coeliac disease or gluten-sensitive enteropathy is an inherited disease caused by an allergic reaction to gluten, a protein found in wheat, rye, and barley. The immune system attacks the lining of the intestines in response to the allergy. This common disease, if left untreated, can leave the intestine unable to absorb essential nutrients and vitamins leading to anaemia, bone disease and, rarely, forms of cancer.

【Gonorrhea】淋病
Contagious venereal infection, transmitted primarily by intercourse. Caused by the bacteria Neisseria gonorrhea.

【Goodell's sign】古德尔氏征象(子宫颈变软)
Softening of the cervix seen as early as probable sign of pregnancy. Goodell's sign may be observed as early as six weeks of pregnancy.

【Grand mal seizure】癫痫大发作
loss of control of body functions. Seizure activity of a major form.

【grasping reflex】抓握反射,握持反射
This reflex is seen when a newborn baby grabs at an object, such as a finger, when it touches her hand. Her hold may be strong enough for you to pull her to a sitting position. The reflex lasts until a baby is three or four months old.

【gravida】孕妇,产妇
The medical term for a pregnant woman.

【grommets】鼓膜通气管
Grommets are tiny ventilation tubes which may be surgically inserted into the ear drum to relieve chronic ear infections, in an operation known as tympanotomy or tympanostomy.

――――――――――――――――――――――――――――――――――――
【H】

【Habitual abortion】习惯性流产
Occurrence of three or more spontaneous miscarriages.

【haemolytic(Hemolytic)disease of the newborn(HDN)】新生儿溶血病
Also called Rhesus disease or erythroblastosis, haemolytic disease results when a woman who is Rh-negative (meaning she does not carry the Rhesus protein in her blood) has a fetus who is Rh-positive and her immune system makes antibodies against the fetus's blood. The disorder is treated with a compound which prevents the woman's immune system from making antibodies.
Anemia in a newborn infant caused by the destruction of red blood cells. In severe cases jaundice, pallor, an enlarged spleen, or hydrops may be present. The condition is usually caused by an incompatibility between the blood types of the mother and her infant. Antibodies to the following blood groups have been implicated in the development of hemolytic disease of the newborn:
●Rh: D , E , c, C, Cw , e
●Kell: K1 , Kpa, k , Jsa ,Jsb
●Duffy: Fya
●MNS: M, S,s, N
●Kidd: Jka

【haemophilia,Hemophilia】血友病,出血不止
A genetic blood disorder characterized by prolonged bleeding and sometimes excessive bleeding., almost always in males, in which blood does not clot properly as a result of an enzyme deficiency.
There may be bleeding into joints, gastrointestinal tract, and urinary tract. On laboratory the activated partial thromboplastin (PTT) time is prolonged. However, the prothrombin time (PT) and bleeding time are normal.
Hemophilia A and hemophilia B (Christmas disease) account for most cases of hemophilia. Hemophilia A is caused by a lack of the blood clotting protein factor VIII, and hemophilia B is caused by a lack of the blood clotting protein factor IX. Hemophilia A is 7 times more common than hemophilia B. Both diseases are caused by a defective gene located on the X chromosome.
Since the male contributes the X chromosome to form female and the Y chromosome to form male offspring, all the daughters of a male affected with hemophilia will be carriers of the defective gene. The daughters of a hemophiliac male will pass the gene to 50% of their male offspring who in turn will have hemophilia.
For the newborn at risk for hemophilia it is best to avoid fetal scalp electrodes, forceps, and vacuum extraction. The pediatrician should be notified of the baby's possible hemophilia. Circumcision, if desired, should be delayed as well as intramuscular injections until coagulation studies are completed and the diagnosis of hemophilia is either established or ruled out.

【haemorrhoid】痔,痔疮
Haemorrhoids are swollen blood vessels in the anus. They are caused by increased blood volume and pressure from the uterus on the veins in the legs and pelvis, and are common during pregnancy. Constipation can also cause (or compound) the problem.

【handedness】用右手或左手的习惯,用手习惯
The preference for using one hand over the other. Most people are right-handed, about 10% are left-handed, and others, who don't favour a hand, are ambidextrous.

【health visitor】〈英〉卫生访视员,保健视察员
A health visitor is a registered nurse with qualifications in obstetrics and midwifery, who visits new mothers and babies at home.

【Heartburn】心灼热,胃灼热
Discomfort or pain that occurs in the chest. Often occurs after eating.

【Hegar's sign】黑格氏征
Softening of the lower uterine segment just above the cervix seen as a probable sign of pregnancy. Originally described by the German gynecologist Ernst Ludwig Alfred Hegar; Hegar's sign may be observed as early as six weeks of pregnancy.

【HELLP syndrome】HELLP综合征
HELLP is an acronym that describes the syndrome of :
H Hemolysis; EL elevated liver enzymes; LP, low platelets.
HELLP syndrome usually presents in the third trimester with right upper quadrant or epigastric pain, nausea, and vomiting. HELLP syndrome is considered to be a variant of preeclampsia. However, unlike preeclampsia hypertension and proteinuria do not need to be present for the diagnose HELLP syndrome. HELLP syndrome occurs in approximately 0.2 to 0.6 percent of all pregnancies. The cause of HELLP syndrome is unknown.
Strict criteria for the diagnosis of HELLP syndrome:
●Hemolysis (characteristic peripheral blood smear) and serum lactate dehydrogenase levels >600 U/L
●Serum aspartate aminotransferase levels >70 U/L
●Platelet count <100,000/mul.
Complications of HELLP syndrome include abruption, disseminated intravascular coagulation, adult respiratory distress syndrome, pulmonary edema, hepatorenal failure, subcapsular hematoma, and hepatic rupture.
Partial HELLP syndrome is also recognized where only one or two features of HELLP syndrome are present.

【Hematocrit】分血器,血球容积计
Determines the proportion of blood cells to plasma. Important in diagnosing anemia.

【Hemoglobin】血红素,血红蛋白
Pigment in red blood cell that carries oxygen to body tissues.

【Hemolytic disease】溶血性疾病
Destruction of red blood cells.

【Hemorrhoids】痔疮,痔疾
Dilated blood vessels in the rectum or rectal canal.

【hepatitis B(HBV)】乙型肝炎
A blood-borne virus (for which there is a vaccine) which primarily affects the liver and, like HIV, has few or no symptoms immediately after infection. It can be passed from mother to child during pregnancy, and can cause cirrhosis, chronic active hepatitis, and liver cancer.
A double-stranded DNA virus in the Hepadnaviridae family. Sexual transmission accounts for most adult HBV infections in the United States. 10-20% of women seropositive for HBsAg transmit the virus to their neonates in the absence of immunoprophylaxis. In women who are seropositive for both HBsAg and HBeAg vertical transmission is approximately 90% . In patients with acute hepatitis B vertical transmission occurs in up to 10% of neonates when infection occurs in the first trimester and in 80 -90% of neonates when acute infection occurs in the third trimester. Chronic infection occurs in about 90% of infected infants, 60% of infected children aged <5 years , and 2%-6% of adults.
The incubation period from time of exposure to onset of symptoms is 6 weeks to 6 months. About one half of acute HBV infections are symptomatic in adults with 1% of cases resulting in acute liver failure and death. Acutely infected individuals develop loss of appetite, nausea, vomiting, fever, abdominal pain and jaundice.
Among persons with chronic HBV infection, the risk of death from cirrhosis or hepatocellular carcinoma is 15%-25%.
HBV infection does not appear to cause birth defects. However, there appears to be a higher incidence of low birth weight and prematurity among infants born to mothers with acute infection during pregnancy.

【hepatitis B vaccine】乙肝疫苗
The vaccine against hepatitis B, a virus which primarily affects the liver.

【Hepatitis C virus (HCV)】丙型肝炎病毒
Hepatitis C virus (HCV) is a single-stranded RNA virus in the Flaviviridae family. Injecting-drug use currently accounts for 60% of HCV transmission in the United States. Blood transfusion, is an uncommon cause of recently acquired infections . Sexual transmission of HCV appears to be inefficient relative to hepatitis B virus (HBV). Transmission between sexual partners of persons with chronic HCV infection with no other risk factors for infection is about 5% (range, 0% to 15%) Household contact with an infected person has been associated with a nonsexual transmission rate of 4% (range, 0% to 11%). Approximately 7-8% of hepatitis C virus-positive women transmit hepatitis C virus to their offspring with a higher rate of transmission seen in women coinfected with HIV .
The average time to seroconversion after exposure to HCV is 8 to 9 weeks. Acutely infected individuals may develop clinically apparent hepatitis with loss of appetite, nausea, vomiting, fever, abdominal pain and jaundice. 60%-70% of patients with acute HCV infection are asymptomatic.
Acute HCV infection progresses to chronic HCV infection in most persons (75%--85%). Cirrhosis develops in 10%-20% of persons with chronic hepatitis C and hepatocellular carcinoma in 1%-5%.. In one small study acute maternal hepatitis appears to have no effect on the incidence of congenital malformations, stillbirths, abortions, or intrauterine malnutrition. However, acute hepatitis may increase the incidence of prematurity. Pregnancy does not appear to be adversely affected by chronic HCV.

【herbal medicine】草药
Herbal medicine uses plants or plant extracts (typically the whole plant or herb is used for the greatest effect) to treat conditions. Herbalists, like many other complementary therapists, treat the whole person and look for underlying problems, rather than specific symptoms.

【hernia】〈医〉疝,突出
Most common in the abdominal wall, a hernia is a bulge of tissue caused by a weak area or tear in the muscle through which tissue protrudes. In babies, hernias are most common in boys or premature infants, and are treated with surgery.

【Hib vaccine】流行性嗜血杆菌疫苗
A vaccine given to protect against Haemophilus influenzae type b (Hib), a serious bacterial infection which causes ear and airway infections and is the leading cause of meningitis in children under two years of age.

【high-risk babies】高危儿
This term describes those babies who have a greater likelihood of developing an illness or dying within the first few months of life. High-risk babies include those born to mothers infected with HIV or to mothers who have a drug or alcohol dependency.

【high-risk pregnancy】高危妊娠
A pregnancy with a higher than normal risk of developing complications. Such pregnancies include those with multiple fetuses or Rhesus incompatibility, or when the mother has had problems with miscarriage, premature labor, or placenta praevia in earlier pregnancies.

【homeopathy】<医>顺势医疗论,类似医疗论
Homeopathy uses highly diluted preparations which correspond to symptoms, clinical signs and pathological states. Homeopathy is based on the theory of similars - that symptoms can be cured with a small dose of that substance which causes the symptom.

【Homocysteine】高半胱氨酸,同型半胱氨酸,巯基丁氨酸
An amino acid produced during the chemical breakdown of the essential amino acid methionine into cysteine. Homocysteine is also used by the body to regenerate methionine.
Elevated homocysteine levels have been associated with neural tube defects, congenital heart defects, recurrent miscarriage, coronary heart disease, stroke, and peripheral vascular disease.

【hormone】<生化>(刺激生长的)荷尔蒙,激素
A chemical messenger from one cell (or group of cells) to another. Hormones are produced to stimulate or slow down various body functions. The levels of some hormones increase ten-fold during pregnancy.

【hot line】热线,热线电话
A telephone number providing direct access to a company or agency for information, advice, and referrals.

【human chorionic gonadotrophin(HCG)】人绒毛膜促性腺激素
This hormone is produced by the placenta and triggers the release of oestrogen and progesterone. As it is excreted in urine, hCG is used in testing to detect pregnancy.

【human growth hormone】人生长激素
The hormone secreted by the pituitary gland which stimulates and regulates growth.

【Human placental lactogen】人胎盘催乳激素,胎盘催乳激素
Hormone of pregnancy produced by the placenta. Found in the bloodstream.

【Hyaline membrane disease】透明膜病
Respiratory disease of the newborn.

【Hydramnios】羊水过多
Increased amniotic fluid.

【Hydrocephaly (hydrocephalus, water on the brain) 】脑积水(脑水肿)
Enlargement of the spaces within the brain (ventricles ) caused by excessive fluid (cerebrospinal fluid). The excessive fluid may cause enlargement of the infant's head.
The abnormally increased fluid may be the result of increased production of fluid, but more commonly is caused by obstruction of fluid flow between the different spaces in the brain. Hydrocephaly has been associated with aqueductal stenosis, spina bifida, X-linked hydrocephalus, Arnold-Chiari malformation , Dandy-Walker malformation, tumors, subarachnoid hemorrhage, infections (CMV and toxoplasmosis) , and chromosome abnormalities ( 8,9,13,15,18,21).
Hydrocephalus is a relatively rare condition caused by swelling of the fluid-filled cavities in the brain (called ventricles). It is also called "water on the brain". It is sometimes the first sign of spina bifida or can be caused by a tumor or surgery to close an open spinal column.

【Hydronephrosis】肾盂积水
Enlargement of the renal pelvis (the part of the kidney that collects urine) to greater than 10 mm. Renal pelvis dilation of 4 to 10 mm in anterioposterior diameter is commonly referred to as fetal pyelectasis. The figure at right shows a normal kidney compared to a kidney with minimal hydronephrosis. Dilatation of the urinary tract is detected in utero in 1 per 100 pregnancies. However, only 1 in 500 cases results in significant pathology.
Hydronephrosis is usually caused by a blockage of the flow of urine along the urinary tract.
Upper urinary tract obstruction is the most common cause of hydronephrosis and may be the result of ureteropelvic junction (UPJ) obstruction, ureteral reflux, or ureterovesical junction. Less common causes of hydronephrosis include posterior urethral valves, urethral atresia, ectopic ureteroceles, duplication of the collecting system, megacystis-microcolon-intestinal-hypoperistalsis syndrome, and cloacal malformation.

【labor】分娩,阵痛
The process of childbirth, from the dilation of the cervix to the delivery of the baby and the placenta.
Regular contractions of the uterus that cause dilation and thinning (effacement) of the cervix leading to the delivery of the infant.
Labor is divided into three stages. The graph (Friedman curve) at right illustrates the expected rate of cervical dilation and duration of each stage of labor in a woman who has never given birth (nulliparous woman).
●The First Stage
The first stage of labor is characterized by dilatation of the cervix with descent of the fetal head into the pelvis. The first stage of labor is divided into a latent phase (early labor) and an active phase (active labor).
The latent phase (latent labor) begins when the mother feels regular uterine contractions accompanied by slow cervical dilation. Latent labor may last up to 20 hours in women who have never given birth to a child, and 14 hours in women who have given birth to a child in the past. Latent labor ends when the cervix is about 3 to 4 centimeters.
The active phase (active labor) begins when the cervix is dilated to 3 to 4 cm in the presence of uterine contractions. During the active phase uterine contractions become more frequent, the cervix dilates more quickly, and the baby descends into the pelvis.
As the mother transitions from the end of the first stage of labor to the beginning of the second stage of labor her contractions may become more frequent and intense. During transition the mother may experience shaking, shivering, nausea, and vomiting. The active phase ends when the cervix has completely dilated to 10 centimeters.
●The Second Stage
The second stage of pregnancy begins when the cervix is fully dilated. The mother will usually feel a strong pressure in her rectum and an urge to push. As the infant's scalp becomes visible the mother will also feel burning and stinging. Loss of bowel or bladder control during the second stage is common. The second stage ends with delivery of the infant.
The second stage usually lasts up to 2 hours in nulliparous women and 1 hour in multiparous women. The "normal" second stage may last up to one hour longer in women who have received regional anesthesia (an epidural).
●The Third Stage
The third stage begins with delivery of the infant and ends with expulsion of the placenta. The third stage may last up to 30 minutes.

【labor suite/room】产房,待产室
The labor suite is where a woman goes through labor and delivers her baby. If the mother is staying in hospital, she will then be transferred to a postnatal ward.

【Laceration (Tear) 】撕裂,裂口

●First-degree: The laceration is limited to the perineal skin and/or vaginal mucosa.
●Second degree: The laceration involves the perineal skin and/or vaginal mucosa, and extends through the underlying fascia and muscles. It does not involve the rectal sphincter.
●Third degree: The laceration involves the perineal skin and/or vaginal mucosa, and extends through the underlying fascia and muscles.The laceration involves the anal sphincter.
●Fourth degree: The laceration involves the perineal skin and/or vaginal mucosa, and extends through the underlying fascia , muscles, and anal sphincter . The laceration extends through the rectal mucosa.

【latching on】(哺乳婴儿)用嘴叼到乳头
To "latch on" to the breast, a baby needs to open his mouth wide. When a baby latches on to the breast successfully, he will be feeding from the breast and not just the nipple. It should not hurt when your baby feeds, although you may experience a strong sensation of sucking.

【Late deceleration】 晚期减速
A gradual decrease in the fetal heart rate with onset of deceleration to nadir >30 seconds. The nadir of the deceleration occurs after the peak of the contraction
Late decelerations are believed to be caused by low oxygen blood levels in the fetus which causes constriction of peripheral blood vessels in order to divert blood to vital organs. Constriction of peripheral blood vessels leads to hypertension which stimulates a baroreceptor mediated vagal response resulting in a decreased heart rate.
Any decrease in uterine blood flow or placental dysfunction can cause late decelerations.

【Low-lying placenta】低置胎盘, 胎盘低置
Most sources define a low lying placenta as being present when the lower edge of the placenta is within 2 centimeters (cm) of the internal cervical opening but is not bordering it.
However, some investigators have proposed that the term placenta previa be used for all placentas with the lower edge within 2 cm from the cervical opening since such patients have been found to have a low chance of successful vaginal delivery in some studies.
It has also been proposed that the term low lying placenta be used if the placental edge is located farther than 2 cm but within 3.5 cm from the internal cervical opening. Patients diagnosed with a low lying placenta using the latter definition have a very good chance of having a successful vaginal delivery.
Patients with a low lying placenta appear to have an increased risk for vasa previa.

First, the phase itself may be too short (only ten days rather than the average 12 to 16), which does not give an embryo enough time to implant successfully. Second, progesterone production in this part of the cycle may be too low, meaning that the lining of the womb will not get thick enough for an embryo to implant before menstruation begins.

【luteinising hormone】 促黃体激素,促黃体生成激素

【Miscarriage (spontaneous abortion, SAB)】流产(自然流产,自发性流产)
The involuntary expulsion of a fetus before the 24th week. After that, the loss of a pregnancy is called a stillbirth.
A pregnancy loss before 20 weeks' gestation calculated from the date of onset of the last menses. Spontaneous abortion occurring before 12 weeks' is called early abortion. Abortion occurring between 12 to 20 weeks' is called late abortion. Up to 20 % of all recognized pregnancies end in miscarriage with 80% occurring during the first trimester.
Symptoms of miscarriage include bleeding with or without cramping.
The risk of miscarriage recurring in a woman with no live births after one miscarriage appears to be approximately 13 %, after two prior miscarriages 25%, and after three miscarriages 50%. However, if she has had a least one live birth the risk having another miscarriage after 3 prior miscarriages is 30%.

【Missed abortion】稽留流产

A bluish-gray birthmark over the lower back and rump of infants that may be mistaken for bruising. Mongolian spots are most commonly seen in infants of African, Asian, Hispanic, and Native American descent. The spots are believed to be caused by entrapment of the cells that produce skin pigment (melanocytes) in the the innermost layer of skin (dermis). They are harmless and most will have completely faded by the age five.

【Montgomery’s tubercles】蒙氏结节
The glands of Montgomery, or Montgomery's tubercles, are the tiny "bumps" that are scattered around the areola (the darker area which rings the nipple). During pregnancy these glands enlarge and they remain enlarged while breastfeeding. They can vary greatly in number, averaging between 4 and 28 per areola. Montgomery originally described these glands as "a constellation of miniature nipples scattered over a milky way."
It is believed that these sebaceous, or oil-producing glands, secrete a lubricating and protective substance, altering the skin's pH and discouraging bacterial growth (Williams 1992). These glands also secrete a small amount of milk (Lawrence 1995). This lubrications helps to keep the skin healthy and the areola elastic.
To preserve the antibacterial function of Montgomery's tubercles, rinsing with clear water while bathing is sufficient. Use of soap on the breasts is unnecessary and may remove these protective oils.

【Neural-tube defect (NTD)】神经管缺损
A general term for birth defects caused by incomplete closure of the cylinder shaped structure, the neural tube, which gives rise to both the brain and spinal cord.
Closure of the neural tube occurs from the middle of the neural groove and progresses toward the ends of the tube. Closure of the end towards the head (cranial) occurs around day 24 and closure of end towards the lower end of the body (caudal) occurs about day 26.
Failure of the cranial end to close results in lack of a complete brain (anencephaly) . Failure of the caudal end to close results in an open spinal cord (spina bifida).
Neural tube defects usually cause elevated serum alpha-fetoprotein levels detectable in the mother's blood and may be seen using sonogram.

【non-stress test(NST)】无应激试验
A test on the fetus which is done by measuring the fetal heart rate in response to his or her movements.
A method of testing fetal well-being. The study is performed by making a graphical recording of the fetal heart rate using an electronic monitor. The test is considered normal (reactive) if there are two or more fetal heart rate accelerations that peak (but do not necessarily remain) at least 15 beats per minute above the baseline and last 15 seconds from baseline to baseline within a 20-minute period with or without fetal movement discernible by the woman.
The nonstress test applies no stress to the mother or fetus. In contrast, the contraction stress test (CST) records the fetal heart rate in response to induced mild contractions of the uterus. The CST tests uteroplacental function whereas the NST tests the fetal condition.

【Norplant】诺普兰,左炔诺孕酮埋植剂<避孕药>
