OBJECTIVE: To discuss the clinical effects of clomiphene citrate combined with low molecular weight heparin calcium in the treatment of patients with polycystic ovarian syndrome(PCOS)infertility. METHODS: A total of 105 patients with PCOS infertility who were admitted to the Outpatient Department of Women and Children's Hospital of Qingdao University from September 2016 to April 2018 were taken as research subjects.They were randomly divided into observation group(57 cases)and control group(48 cases).The control group received clomiphene citrate for ovulation treatment,the observation group was given clomiphene citrate combined with low molecular weight heparin calcium for ovulation treatment,and the endometrial receptivity changes,pregnancy rate and the incidence of adverse reactions of patients were compared between the two groups.RESULTS: In the observation group,the endometrial thickness,blood flow index(FI),endometrial spiral arterial blood flow resistance index(RI)and pulsatility index(PI)decreased,and the pregnancy rate was better than that in the control group;the difference was statistically significan(t P<0.05).There was no statistically significant difference in the incidence of adverse reactions between the two groups(P>0.05).CONCLUSION: Clomiphene citrate combined with low molecular weight heparin calcium in the treatment of polycystic ovary syndrome infertility can improve the treatment efficiency,and is safe and reliable.It is worthy of clinical promotion.

Objective　To compare the irradiation-protective and inter-synergestic effects of E838,WR-2721, Rubia cordifolia, cystamin e hydrochloride and ethinyl estradiol on radiation and combined radiation-burn injury. Methods　Above-mentioned drugs were given to the mice i ntraperitoneally, or intragastrcally, then, the mortality and the average surviv al d for 30 d were observed before and after the administration of the drug s. Results　①When drugs were before injury , the survival rate and the average survival d of the radiation and combined radiation-burn injured mice were increased obviously with the best effect in E838 and WR-2721. ②When drugs were given after injury, E838 and R. cordifolia also kept the effect. ③Combined appling WR-2721（pre) and E838（post）displayed a significant syner gistic reaction. Conclusion　E838 and WR-2721 are more e ffective than the others in the prevention of radiation.
