ABSTRACT. SET8, a member of the SET domain-containing methyltransferase, has been implicated in various biological processes. In this study, SET8 was immunostained in 100 samples of gastric cancer tissues and semi-quantified using the HSCORE method to determine the predictive value of SET8 expression levels for gastric cancer outcome. The relationship between SET8 expression and the 5-year survival rate of gastric cancer patients was assessed. High expression of SET8 was associated with a shorter survival time in gastric cancer patients, and the level of SET8 expression was found to be an independent predictor of gastric cancer outcome (relative risk = 1.939; 95% confidence interval = 1.025-3.668; P = 0.042). Analysis of SET8 levels may help in the identification of patient subgroups that are at high risk for poor disease outcomes.

Information on the prevalence and incidence of sexually transmitted infections is important for developing prevention and control strategies and allocating human and financial resources. However, there are no available estimates of such information for many areas in China. In this study, we used the existing data to make a preliminary estimation of syphilis infections in Shenzhen city, in south-eastern China. Data on prevalence rates of syphilis infections among different populations were obtained from the local HIV/sexually transmitted disease second-generation surveillance programme, and the sizes of different populations were estimated based on the most recently available figures. It was estimated that 83,760 (range 77,490-90,020) people are currently infected with syphilis, giving a prevalence of 0.71-0.82% (0.76% on average) in Shenzhen. Around 18% of these syphilis infections occur among men who have sex with men and another 15.8% and 8.7% occur among female sex workers and their clients, respectively. These estimates suggest that a combination of unprotected paid sex and sex between men may be sustaining the epidemic of syphilis in the study area. The preliminary estimates will assist the government in planning and improving its comprehensive intervention programmes for the future control and prevention of syphilis.

INH and RMP resistance and MDR-TB rates declined significantly, suggesting that DOTS-based programmes were successful in reducing drug resistance in new cases but not in retreatment cases. The decreasing sputum smear conversion rates may have been due to an increase in the number of migrants. These two findings suggest that TB is unlikely to be completely eliminated by 2050 in Shenzhen.

This study suggests that further technical refinement-namely, shortening the anhepatic phase duration, shielding the hepatic artery, and refining biliary duct reconstruction-can reduce the incidence of biliary complications following liver transplantation.
