Objective:To investigate the present situation of medical students′medical ethics education and fur-ther to put forward countermeasures for medical colleges and universities. Method:With the methods of question-naire, literature and interview, medical students of the second grade and above in Xi′an Jiaotong University, Xin-jiang University and Xinjiang Medical University were investigated. SPSS 20. 0 was used to establish a database and frequency analysis method was used to analyze data. Results:It is suggested that some medical students′ motiva-tion to be a doctor is pure and the professional ethical identity is correct. There exist problems in the evaluation of ethics anomie behaviors. The students lack of cognition of medical ethics but pay more attention to medical technol-ogy. Most of the medical students think that clinical practice education and the model demonstration of teachers are conducive to medical ethics education. Conclusion: Universities can develop their own medical ethics education mode through various forms of classroom education, the involvement of old professors in teaching, strengthening learning of medical laws, daily ideological education by counselors and the construction of campus spiritual civiliza-tion.

To investigate the effect of autoimmune regulator (AIRE) on phagocytic clearance of apoptotic cells, a recombinant expression vector containing full-length human AIRE cDNA was transfected into 16HBE cells. After incubation with transfected 16HBE cells, engulfment of apoptotic HL-60 cells induced by camptothecin was detected by myeloperoxidase (MPO) staining. The change in the expression of Rac 1 in transfected 16HBE cells was determined by RT-PCR and Western blotting. The results showed that the phagocytosis percentage of the experimental group, the mock transfection group and the negative control group (non-apoptotic cells) was (25.50+/-3.67)%, (6.25+/-1.58)% and (1.0+/-0.67)%, respectively. Moreover, the expressions of Rac 1 mRNA and protein were up-regulated in AIRE-transfected 16HBE cells, suggesting that AIRE may function as a regulator in the phagocytic clearance of apoptotic cells by promoting the expression of Rac 1.

Objective To investigate the change of serum CA724, CA242 and AFP levels before and after transcatheter artery chemoembolization (TACE) treatment of primary hepatic carcinoma(PHC)patients as well as its clinic significance. Methods Patients of PHC (n=45) and healthy adults (n=40) were enrolled. Serum samples were collected from each healthy people and PHC patients 2 days before TACE,l week and 1 month after TACE. Electrochemiluminescence Immunoassay (ECLI) was used to determine serum CA724, CA242 and AFP levels, and correlations among three indexes as well as their relationships with clinical data were also analysed., Change of serum CA724 and CA242 levels before and after TACE were compared in AFP<400μg/L group and AFP≥400μg/L group. Results Serum levels of CA724, CA242 and AFP in PHC group were significantly higher than that in healthy control groups before TACE therapy(P<0.05). Positive rates of serum CA724 and AFP were higher in PHC group(P<0.01)than that in healthy control group. AFP decreased significantly at both 1 week and 1 month upon TACE treatment compared with that at before teratment(P<0.01). CA724 was significantly lower at one month after treatment than that at before treatment(P<0.05). But there was no significant difference in CA242 before and after treatment(P>0.05). CA724 and AFP expressions are associated with tumor size(P<0.05). After one month of therapy, serum CA724 level was obviously decreased in both AFP<400μg/L and AFP≥400μg/L groups. Before and after TACE therapy, there was a positive correlation between the expression of AFP and CA724(r=0.754,P<0.05). Conclusion Serum CA724 can be used as one of the tumor markers to assist the evaluation of curative effect of TACE on PHC.

Objective To assess the prevalence of the metabolic syndrome (MS) in Shanghai adults according to the criteria of the US National Cholesterol Education Programme Adult Treatment PanelⅢ ( NCEP ATP Ⅲ) definition. Methods Randomly selected adults were studied by means of stratified sampling. A cross-sectional study was conducted in Shanghai with a representative sample of 7 414 Chinese adults aged 35-74 years.Results Defined by the ATPⅢ criterion, the preliminary prevalence of MS was 19.81%. The prevalence of MS was 16.21% (95%CI 15.37%-17.05% ) after age was adjusted. The prevalence of MS was higher in female than in male (22.59% vs 16.64% ,P<0.01 ), and higher in urban than rural residents( 17.43% vs 17.16% ,P<0.01 ). The prevalence of MS increased with age in both male and female, especially in females aged above 55 years. There were 19.81% subjects with over 3 risk factors. The most common combination of four components in MS were central obesity, high triglyceridemia, low high-density lipoprotein-cholesterol and hypertension. Conclusions There is a high prevalence of MS in Shanghai adults. MS is increasingly becoming a noteworthy health problem. Early-diagnosis and integrated-methods of prevention and treatment of MS are mandatory.

Objective To discuss the clinical manifestation and treatment of the complications caused by injected polyacrylamde hydro-gel( PAAG) for breast augmentation. Methods This retrospective research was performed among 212 patients who undergoing breast aug-mentation with injected polyacrylamde hydrogel. The clinical manifestation and treatment outcome of the complications were analyzed and summarized,which is aim to search an effective treatment method. Results For the 212 patients,the main complications were breast multi-ple indurations (131 cases),fever (9 cases),infection (14 cases),breast pain (65 cases),PAAG displacement (28 cases) and secondary deformity or asymmetry (25 cases). 152 cases experienced one clinical symptom,the rest patients simultaneously undergone no less than two clinical symptoms. Patients were received open operation with periareolar incision ( surgery group) or vacuum absorption by needle ( aspira-tion group) for dislodging PAAG. No significant difference was found in wound healing,breast shape satisfaction and pain anesis between the two groups. Whilethe surgery group was better than the aspiration group in efficiency for taking out PAAG and the incidence of reoperation, with statistical significance. Conclusion A plenty of complications occurred after breast augmentation with injected polyacrylamde hydrogel, the method of open operation with periareolar incision is a better way for eliminating PAAG and treating the complications.
