Objective To investigate the clinical effect of the Yiqixue Buganshen Recipe(YBR)on the level of serum VEGF in high-risk patients with OHSS. Method 298 infertile women with high-risk OHSS in the reproductive centre of our hospital from June to November ,2016 were enrolled into the traditional Chinese medicine (TCM) group (n = 148) and the control group(n = 150). 145 infertile women without high-risk OHSS were enrolled into the normal group. All the patients received the long protocol treatment ,and patients in the TCM group received the YBR treatment. Results Patients have higher quality embryo rate ,lower moderate and more severe OHSS rate in the TCM group compared with the control group(P<0.05). Patients in the normal group have lower serum VEGF compared with patients in the other 2 groups on the all three days. Patients in the TCM group has lower serum VEGF on the day of embryo transfer compared with patients in the control group(P<0.05). Conclusions The increment of the serum VEGF level is closely related to OHSS. The YBR may reduce the rate of moderate and severe OHSS by reducing the serum VEGF level on the day of embryo transfer ,which may prevent the moderate and severe OHSS of the high-risk patients.

Objective To assess the effects of Jinghou Zengzhi Recipe ,a Chinese prescription with the action of tonifying Qi and blood,on the expressions of Bcl-2,Bax and Caspase3 in ovarian granulosa cells of con-trolled ovarian hyperstimulation(COH)mice. Methods A model of COH mice was prepared and 30 female KM mice were divided into blank group,model group and treatment group. The expressions of Bcl-2,Bax and Cas-pase3 were detected by Real-time Quantitative PCR and Western Blot.

Objective To analyze epidemiological characteristics of elderly cases with influenza A (H1N1) in Beijing. Methods Descriptive epidemiological methods were used to describe epidemiological characteristics of elderly cases with 2009 influenza A (H1N1) in Beijing. Results The 321 laboratory-confirmed elderly cases with influenza A (H1N1) were reported in Beijing, and the morbidity was 13.2/100 000. The peak of infection occurred during November and December, the cases in this period accounted for 84.7% of the whole year, and 53.0% of them were reported in suburb areas, with the highest morbidity (19.2/100 000) in people beyond 85 years, and the morbidity increased with age (x2 = 7.24, P＜0.01). The mild cases accounted for 63.6 %, severe and critical cases accounted for 36.4%. No significant difference was found between severity and BMI (x2=8.14, P=0.52). Severity was associated with number of chronic diseases (x2= 123.0, P＜0. 01). Conclusions The H1N1 morbidity and proportion of severe cases are high among the elderly in Beijing, more attention should be paid to this population for influenza A (H1N1) prevention and control.

Objective To assess the effects of Jinghou Zengzhi Recipe(JHZZR),a Chinese prescription with the action of tonifying Qi and blood ,on the ovary apoptosis and expression of Bim in ovarian granulosa cells (GCs) of controlled ovarian hyperstimulation(COH) rats , and analyze the possible therapeutic mechanism. Methods A model of COH rats were prepaered and 30 female SD rats were randomly divided into 5 groups , including control group,positive control group,low,medium and high concentration group in six rats in each group.

Objective To observe the effect of Yiqixue Buganshen Recipes(YBR), the compound recipes of Chinese herbal medicine with the actions of replenishing Qi and blood and tonifying liver and kidney, on the endometrial integrin β3 of the mice with embryo implantation dysfunction, and to explore the molecular mechanism of YBR in improving embryo implantation. Methods Ninety mice were divided normal group, model group, and YBR group, 30 mice in each group. YBR group was given Jinghou Zengzhi granules 8mg/kg for promoting post-menstruation proliferation and Cuhuangti granules 8mg/kg for promoting the formation of corpora luteum. At 8∶00 am of pregnant day 4 (Pd4), subcutaneous injection of mifepristone was used for inducing embryo implantation dysfunction in the model group and YBR group. Twenty mice from each group were executed 12 hours after subcutaneous injection of mifepristone, and the uterus was isolated for the detection of mice endometrial integrin β3 mRNA and protein expression with real-time RT-PCR and Western blotting method respectively. Ten mice from each group at Pd4 were executed, and the uterus was isolated and then fixed in 2.5% glutaraldehyde solution for the detection of the formation of pinopode in mice endometrium under scanning electron microscope. Results The detection by real-time PCR and Western blotting method revealed that integrinβ3 mRNA and protein expression levels of the model group were significantly lower than those of the normal group (P<0.05), and YBR group had higher integrin β3 mRNA and protein expression levels than the model group(P<0.05). The formation of pinopodes in the model group was less than the normal group and YBR group, but the number of formed pinopodes in YBR group was similar to that in the normal group. Conclusion YBR can up-regulate the expression of integrin β3 in the endometrium of mice with embryo implantation dysfunction, and have positive regulatory effect on the formation of pinopodes on Pd4.
