Objective To investigate the inhibitory effect and the mechanism of endostatin on human gastric carcinoma model in nude mice. Methods Athymic mice were injected by in vitro-cultured SGC-7901 human carcinoma cell strain to observe the inhibitory effect of endostatin. Real time fluorescent quantitative PCR and immunohistochemistry stain were used to quantify the expression levels of Bcl-2 and Bax genes both on mRNA and protein levels. Results The average tumor volume in endostatin group was statistically smaller than control group (P<0.05). The inhibitory rate on the 7~(th), 10~(th), 13~(th), 16~(th) and 19th day was 26.2%, 47.7%, 38.9%, 45.8% and 51.7%, respectively. The results of real time fluorescent quantitative PCR demonstrated that mRNA expression of Bcl-2 in endostatin group was obviously lower than it in control group (P<0.05), however, the expression level of Bax had no statistical difference between these two groups (P>0.05). The results of immonohistochemistry were consistent with PCR. Conclusions Endostatin can inhibit the proliferation of SGC-7901 human gastric carcinoma in athymic mouse model, and the mechanism involves the suppression of Bcl-2 expression.

AIM: To investigate the effect of 17? estradiol (17?E 2)on atherosclerosis and hemorrheology in ovariectomized (OVX) rabbits. METHODS: Thirty four female rabbits were divided into 4 groups, group A: normal control; group B: sham+CHO; group C: OVX+CHO; group D: OVX+CHO+17? E 2. Cholesterol(CHO) was fed to rabbits for 12 weeks, before and after feeding CHO, the serum lipid (TC, TG, HDL-C, LDL-C, ApoA1, ApoB) and area of aortic atherosclerotic plaques were measured. Blood viscosity, plasma viscosity (?p), aggregation index of RBC (AIRC) and fibrinogen were also determined, respectively. RESULTS: ① The ratio of area of aortic atherosclerotic plaque to total area of aortic intima was 0.02?0.003 (in group A), 0.42?0.15 (group B), 0.67?0.23 (group C), and 0.12?0 11 (group D), respectively. In group D, the ratio of aortic atherosclerotic plaque was markedly decreased compared with group C ( P

OBJECTIVETo investigate gay identity status of men who have sex with men(MSM) in Xinjiang, and analyze its association with sexual behaviors.
METHODSFrom May to August in 2013, an anonymous questionnaire survey with convenience sampling was conducted among MSM in Urumqi, Kashgar, Aksu and Yining cities of Xinjiang. Those who were ≥ 16 years of age and claimed to have male-to-male sex behaviors were eligible for the survey. A total of 1 467 participants were recruited. Chi square analysis was performed for examining the association between ego-identity, social-identity and relevant sexual behaviors. Selected variables associated with ego-identity, social-identity in the univariate analysis were subsequently assessed in a multivariate analysis using logistic regression.
RESULTSThe MSM with positive ego-identity accounted for 44.7% (656/1 467), and positive social-identity accounted for 29.1% (427/1 467). For ego-identity, Uyghur MSM were less positive than Han MSM (OR (95%CI) was 0.43 (0.32-0.58) ) ; those who were over 20 years of age when accepting their sexual orientation were less positive than those who were younger than 20 years of age when accepting their sexual orientation (OR (95%CI) was 0.61 (0.47-0.80) );and homosexuals were more positive than bisexuals (OR (95%CI) was 1.98 (1.50-2.61) ). For social-identity, Hui MSM were less positive than Han MSM (OR (95%CI) was 0.61 (0.42-0.88) ); those whose education level was higher than college were less positive than those with junior high education (OR (95%CI) was 0.60 (0.40-0.89) ); famers/herdsmen were more positive than students (OR (95%CI) was 4.17 (2.13-8.17) ); the divorced/widowed were more positive than the singles (OR (95%CI) was 2.40 (1.34-4.29) ); those who were over 20 years of age when accepting their sexual orientation were less positive than those who were younger than 20 years of age when accepting their sexual orientation (OR (95%CI) was 0.59 (0.44-0.81) ). Among the MSM with negative ego-identity and negative social-identity, the proportion of planning to get married with women was 66.8% (267/400) and 76.5% (306/400), respectively, which were higher than those with positive ego-identity (33.2% (133/400)) and positive social-identity (23.5% (94/400)) ; their proportion of intending to have offspring was 62.0% (287/463) and 73.4% (340/463), respectively, which were higher than those with positive ego-identity and social-identity (38.0% (176/463), 26.6% (123/463)) (χ(2) = 39.61 and 7.90, respectively, both P values were <0.05). Among the MSM with negative social-identity, the proportion of looking for male sexual partners in toilets or parks was 18.1% (188/1 040), in bathhouse or sauna was 17.3% (180/1 040), and through internet was 82.0% (853/1 040), which were higher than those with positive social-identity (8.9% (38/427), 9.8% (42/427) and 61.6% (263/427)) (χ(2) = 66.78, P < 0.01).
CONCLUSIONIn 2013, the gay identity of MSM in Xinjiang was relatively poor, and the factors associated with it included ethnicity, occupation, marital status and education level. The MSM with negative identity tended to involve in risk sexual behaviors, and had increased risk of HIV infection.

Objective:To evaluate the biological characters of C57-TgN(HBV adr2.0)SMMU transgenic mice. Methods: Integration,expression,replication and histology change of hepatitis B virus gene in F6 transgenic mice were estimated by ge-nomic DNA PCR,Western blotting,ELISA,immunohistochemistry,serum DNA PCR,transmission electron microscopy and H-E staining. Results: Hepatitis B virus gene was integrated into F6 C57-TgN(HBV adr2. 0)SMMU transgenic mice and expressed HBsAg,HBcAg and X protein in liver tissue. HBsAg and HBeAg were expressed in serum of 19. 54% and 3. 39% F6 transgenic mice. Hepatitis B virus were replicated in serum and liver tissue of transgenic mice. Long-term integration,expression and replication of hepatitis B virus gene induced pathological lesion of transgenic mice liver and lung. Conclusion: C57-TgNCHBV adr2. 0)SMMU transgenic mice line has the biological characters including integration of hepatitis B virus gene into genomic DNA,expression and replication of hepatitis B virus gene in serum and liver, and histological change in liver and lung. It is a valuable animal system to study pathogenesis, treatment and prevention of hepatitis B virus.

Purpose:
Cervical cancer is one of the most fatal diseases among women in under-developed countries. To improve cervical cancertreatment, discovery of new targets is needed. In this study, we investigated the expression of NUP210, miR-22, and Fas in cervicalcancer tissues and their functions in cell cycle regulation.
Materials and Methods:
We detected and compared the expression levels of NUP210, miR-22, and Fas in cervical cancer tissueswith paired normal tissues using immunohistochemistry, Western blot, and real-time quantitative polymerase chain reaction.NUP210 was knocked down in HeLa cells via lentivirus, followed by cell cycle and proliferation analysis. Using a luciferase reporterassay, we explored the link between miR-22 and NUP210. We overexpressed miR-22 in HeLa cells and analyzed cell cycle and proliferationfunction. We then overexpressed miR-22 in NUP210 knockdown cells to explore the connection between Fas and miR-22-NUP210 signaling.
Results:
We found that NUP210 was overexpressed in cervical cancer patients. Knocking down NUP210 restored cell apoptosisand proliferation. We confirmed miR-22 as a regulator of NUP210 and verified that miR-22 was inhibited in cervical cancer development.We also found that restoring miR-22 expression could induce cell apoptosis. Finally, we found that miR-22-regulated expressionof NUP210 could alter Fas expression and, in turn, elicit cell cycle arrest and proliferation.
Conclusion
miR-22 in cervical cancer is downregulated, resulting in NUP210 overexpression and inhibition of Fas-induced cellapoptosis.
