Objective:To investigate the effect of ethyl acetate extract from Cortex periplocae (CPEAE) on apoptosis of human esophageal carcinoma cell line TE-13 and to elucidate its mechanism. Methods:Inhibitory effect of CPEAE on TE-13 proliferation was tested by MTT assay. The morphological changes of cell apoptosis were observed by Giemsa staining and transmission electron microscopy. Cell cycle and apoptotic ratio were tested by flow cytometry (FCM). The protein expression of CDK4 was observed by Western blotting.Results:CPEAE inhibited proliferation of TE-13 cells in a concentration-dependent and time-dependent manner, and its IC_(50) value was (2.443±0.005) μg/mL at 48 h (P<0.05). The characteristic morphological changes of apoptosis were observed in TE-13 cells after treatment with CPEAE under transmission microscope. A typical subdiploid peak was detected by flow cytometry. CPEAE decreased the expression of gene CDK4 in TE-13 cells. Conclusion:CPEAE can induce apoptosis of TE-13 cells. The effect is related with down-regulation of CDK4 expression.

To explore the effect of estrogen on pathogenesis of osteoporosis in women with maintenance hemodialysis. One hundred and twenty women aged 18-45 years had been undergoing maintenance hemodialysis for ≥ 3 months were included. Of them ,60 women without osteoporosis served as control group and the other 60 women with osteoporosis as observation group. Serum concentrations of estradiol, tumour necrosis factor-α (TNF-α), parathyroid hormone (PTH), and calcium were determined, meanwhile bone mineral density (BMD)was measured by quantitative computed tomography. Serum estradiol levels in the observation group were lower while TNF-α level were higher than those in control group (all P<0. 05). PTH and calcium levels were not significantly different (P= 0.567 and P = 0. 588). In the observation group, linear correlation analysis revealed positive correlation (r = 0. 865 ,P<0. 01)between estradioi and BMD,while multiple linear regression analysis showed that serum estradiol and calcium levels were positively correlated with BMD, and the concentrations of TNF-α and PTH were negatively correlated with BMD (F= 140.32 ,P<0.01). Estradiol levels were found to have greater effect on BMD(t=5. 386, P<0. 01). Lowered serum concentration of estradiol in women with maintenance hemedialysis seems to be a major factor related to osteoporosis,it accelerates the pathogenesis of osteoporosis by modulating TNF-α.

Objective To investigate the killer cell lg-like receptors (KIR) gene frequency of HIV-1 infected slow progressors(SP) and typical progressors(TP), and to analyze the interaction between KIR alleles and the progression of HIV-1 infection in Chinese population. Methods Eighty-one HIV-1 posi-tive individuals including 43 SPs and 38 TPs were recruited. Carriage of KIR genes was assessed using poly-merase chain reaction sequence-specific primers (PCR-SSP) assays. Results KIR2DS3 gene frequency was significantly lower in SP group (3.6%) than that in TP group (14.2%), P =0. 018 ,OR =0. 210,95% CI =0.053-0.833. The number of activating KIR genes was less in SP group than that in TP group, but was not significant (P = 0. 208). Conclusion Lower KIR2DS3 gene frequency may potentially be associated with slower progression to AIDS in Chinese population.
