Thirty healthy women and 101 patients with polycystic ovary syndrome (PCOS) were recruited. According to serum testosterone (T) level and homeostasis model assessment for insulin resistance (HOMA-IR) ,the correlation of T and body mass index (BMI) with insulin resistance was analyzed. The results showed that there were 39. 8％ normal,24. 5％ overweight,and 35.7％ obese among 101 PCOS patients. However,there were no significantly differences in BMI, fasting plasma glucose ( FPG ), triglyceride ( TG ), total cholesterol ( TC), low-density lipoprotein-cholesterol ( LDL-C), high-density lipoprotein-cholesterol ( HDL-C ), and HOMA-IR levels between PCOS patients with hyperandrogenemia ( T ≥ 0. 51 μg/L) and normal androgenemia ( T ＜ 0. 51 μg/L). BMI, FPG, TG, TC, and LDL-C levels were higher and HDL-C level was lower in patients with insulin resistance( HOMA-IR ≥ 2. 29 ) than in patients without insulin resistance ( HOMA-IR ＜ 2. 29, P＜0. 05 or P＜ 0. 01 ). Serum T levels were not significantly different between two groups. HOMA-IR was significantly correlated with BMI(P＜0. 01 ), not with serum T, suggesting that the gain of body weight is correlated with insulin resistance independent of serum T level.

This study is to investigate the effect of ethyl gallate on invasion capabilities and its mechanism of breast cancer MDA-MB-231 cells. Using cell adhesion and transwell assay, separately, the effects of ethyl gallate on the invasion of MDA-MB-231 cells were measured. The Akt-NF-κB signal pathway protein expressions were analyzed with Western blot. Also, the mRNA levels of MMP-9 and MMP-2 were analyzed by RT-PCR. Ethyl gallate inhibited the abilities of motility, adhesion and invasion of breast cancer MDA-MB-231 cells in vitro (P<0.05), inhibited the mRNA levels of MMP-9, MMP-2, phosphorylation of AKt and protein expression of NF-κB. It is concluded that ethyl gallate can inhibit the abilities of invasion of breast cancer in vitro by inhibiting the mRNA levels of MMP-9/MMP-2, phosphorylation of Akt and protein expression of NF-κB.

OBJECTIVE: To investigate the development of the enteric nervous system(ENS) in the middle stage(the 4th approximate, equals 6th months) of human embryogenesis. METHODS: A histologic evaluation of the clonic enteric nervous system was done using NADPHd histochemistry, PAP immunohistochemistry, with anti-PGP 9.5 and anti-S-100 protein. RESULTS: During this stage of embryology three things were noted. (1)The nerves in the myenteric layer increased markedly. This was shown by the PGP 9.5 immunoreactive nerves spreading out and the S-100 protein immunoreactive nerves forming a "bamboo basket"pattern. (2)The whole myenteric colon showed nitrigeric nerves paralleling the growth of the myofibers in the circular muscle layer. Nitrigeric perikara were rarely found in the extrinsic submucosal layer.(3) In the whole-mounted preparations reactive nerves formed the complex nerve net in the myenteric layer. CONCLUSION: The middle stage of embryogensis is very important to the development of the colon ENS.

Objective To evaluate the preventive effect of orifices-dredging and stasis-removing therapy on retinal vascular endothelium and optic nerve damage induced by radiation in rats. Methods Thirty-six SD rats were randomly divided into 3 groups, namely blank control group, model group and therapy group. Rats in the model group and therapy group were exposed to X-ray radiation once a week for three weeks. Two weeks before the radiation, therapy group was pretreated with intraperitoneal injection of Astragalus injection ( 4.0 g/kg) , Ligustrazine Hydrochloride injection ( 15 mg/kg) and Xingnaojing injection ( 2.5 mL/kg) once a day, blank control group and model group were given intraperitoneal injection of same volume of saline once a day. Before radiation, one day, and 2, 4 and 6 weeks after radiation, we detected the blood concentrations of endothelin-1 ( ET-1) and Von willebrand factor (vWF) in all of the rats by enzyme-linked immunosorbent assay (ELISA) , and analyzed the dynamic changes and intergroup difference. Demyelination of optic nerve was observed under transmission electron microscope, and demyelination percentage was counted 2, 4, and 6 weeks after irradiation. Results Compared with the blank control group, the blood concentrations of ET-1 and vWF in model group were increased after irradiation (P<0.05) , and the peak value appeared on the fourth week after irradiation. Compared with the model group, the blood concentrations of ET-1 and vWF in the therapy group were decreased weeks 2 after irradiation ( P<0.05) . The demyelination percentage of optic nerve was significantly higher in the model group than that in the blank control group (P<0.05) 2, 4, and 6 weeks after irradiation. Compared with the model group, the demyelination percentage of optic nerve in therapy group showed insignificant changes 2 and 4 weeks after irradiation (P>0.05) , but was decreased obviously 6 weeks after irradiation (P<0.05) . Conclusion Pretreatment with orifices-dredging and stasis-removing therapy can decrease the blood concentrations of ET-1 and vWF in the radiation-induced retinal damage rats, and can reduce the demyelination of optic nerve in irradiated rats.
