    Among a total of 20,067 pregnant women ad- mitted to the Lying-In Hospital of the Shanghai First Medical School in the three-year period from January 1953 to December 1955,there were 342 cases of heart disease,giving an incidence of 1.7%.The etiological types of heart disease were,in their order of frequency,as follows:rheumatic heart disease 65.2%,heart failure due to toxemia of pregnancy 14.3%,congenital anomalies of heart 9.3%,anemia heart disease 5.3%,hypertensive heart disease 2.7%,and others 3.2%.

    Among a total of 20,067 pregnant women ad- mitted to the Lying-In Hospital of the Shanghai First Medical School in the three-year period from January 1953 to December 1955,there were 342 cases of heart disease,giving an incidence of 1.7%.The etiological types of heart disease were,in their order of frequency,as follows:rheumatic heart disease 65.2%,heart failure due to toxemia of pregnancy 14.3%,congenital anomalies of heart 9.3%,anemia heart disease 5.3%,hypertensive heart disease 2.7%,and others 3.2%. Only 5 patients were submitted to therapeutic abortion.In no case was artificial termination of pregnancy attempted after the third month of gestation. The maternal death rate in this series was 2.9%.Among the 241 pregnant cardiacs who re- ceived antenatal care,there was only one death, the death rate being 0.4%,whereas the number of deaths among 101 patients not receiving antenatal care was 9,giving a death rate of 9%.The im- portance of early and adequate management as a prognostic factor in heart disease associated with pregnancy is thus quite obvious. Heart failure due to toxemia of pregnancy carried with it a grave prognosis concerning both the mother and the fetus.Among the 10 maternal deaths in this series,6 were due to heart failure caused by toxemia of pregnancy. Although the maternal death rate from heart disease in the present study has shown a signifi- cant drop in comparison with earlier years,heart disease constituted the main cause of death in the obstetric service during the period under study. It is believed,however,that in the future,if more pregnant women can receive adequate antenatal care,a further decline in the death rate from heart disease in pregnancy may be expected.

    一、本报告分析了我院由1953至1955年三年内妊娠期心臓病342例,并对其处理及预后加以讨论。二、本组病例中心臓病的病因分类如下:风湿性65.2%,妊娠中毒症性14.3%,先天性9.3%,贫血性5.3%,高血压性2.7%,其他3.2%。三、342例中施行人工流产者仅5例,占1.4%。怀孕超过三个月者并无一例试行人工终止妊娠。四、本组病例的死亡率为2.9%,经本院产前检查的241例中仅一例死亡,死亡率为0.4%。未经产前检查101例中,有9例死亡,死亡率为9%。可见及时与适当的处理对预后有决定性的意义。五、妊娠中毒症心臓病对母亲与胎儿的预后均十分恶劣,本组内10例死亡中有6例系由本病所引起。六、三年来心臓病产妇死亡率较前有了显著的降低,但仍占产科死亡原因中主要地位。相信今后如果能改进与加强产前检查和处理,心臓病产妇的死亡率尚有进一步降低的可能。本文的完成,承蒙妇产科教研组王淑贞、司徒亮等教授及其他同志的指正与帮助,特此致谢。

    Radix trichosanthes is an abortifacient drug of mid-gestation and is extracted from the root tuber of Trichosanthes kirilowii Maxim (Cucurbitaceae).The purified effective principle is a basic protein of molecular weight of appoximately 18,000 and is named "Trichosan'thin".It is proved to be very effective in abortion induction of mid-gestation,particularly effective in treating ectopic pregnancy,hydatidiform mole and invasive mole,and it has also some therapeutic action on choriocarcinoma.Based upon the experimental results on its initial site of action,its morphological and functional injury on trophoblast cells of placenta both in vivo and in,vitro and its effect on prostaglandin synthesis,the following conclusions are drawn concerning the mechanism of abortifacient action of triohosanthin:(1)Trichosanthin exerts its action directly on the placental trophoblasts and possesses a certain degree of specificity.(2)It selectively produces necrotic degeneration of the syneytiotrophoblasts of placental villi,resulting in fragments of the disintegrated cells clumped in the blood sinus,and the coagulation of blood causing circulation hinderan'ce and followed by large scale tissue necrosis.The necrosis of placental villi is considered to be the primary response.(3)Beside structural injuries the impairemerit of functional activities were also observed.The concentrations of HCG and steroid hormones fell rapidly below the threshold values of threatened abortion.Serious structural and functional injuries brought about destructive effects upon the normal endocrine relationship between the mother and fetus and upon metabolic exchanges.It was further postulated that through certain unknown mechanism the synthesis of prostaglandin was increased,uterine contraction was initiated and abortion ensued.In summary,trichosanthin,a plant protein discovered from Chinese medical herbs,is a drug for abortion induction and also a drug against trophoblastie neoplasms.The preliminary elucidation of the mechanism of this drug on abortion induction has afforded basis for the clinical application with better efficacy and its possible use for an abortifacient in early pregnancy as well as for the discovery of newer cancer chemotherapeutie agents.
