Objective To explore the key influencing factors of HIV risk behavior among male who have sex with male (MSM). Methods 36 MSM subjects in a community were recruited for HIV risk behavior characteristics, social environment and the attitude of exposure of high risk sexual intercourse, using behavior scales and qualitative research methods. The collected data were orderly input and analyzed using Nvivo 8.0 software. Then, after three-level transcription, the data were further summarized and extracted based on the method of the grouding theory. Results The HIV Risk Assessment Questionnaire score of 36 subjects was 8.08±2.46, of whom, 72% scored at a medium level (5 to 10 scores) and 19% scored at a high level (more than 10 scores). The social support rating scale (SSRS) score was 32.38±5.99 in MSM population, lower than in undergraduates and floating population. The results of qualitative analysis showed that, after open coding, 11 key message and 4 categories contributed to HIV risk in MSM populaiton, including: a) low levels of fear for AIDS; b) male role and uncertain sexual orientation; c) low degree social support; and d) poor availability of condom in the setting of sexual intercourse. Conclusion The interventions against AIDS/HIV for MSM need to be further studied. Besides, we should strengthen the community intervention mode based on fear for AIDS, social support, and condom distribution methods
Objective To investigate the clinicopathological features, postoperative survival and prognostic influencing factors of male patients with hepatocellular carcinoma （HCC）. Methods The clinicopathological features and the follow-up data of 155 male HCC patients who received hepatectomy from Jan. 1995 to Dec. 2002 were retrospectively analyzed and the prognostic influencing factors were defined by uni- and multi-variate analysis. Results Compared with 24 female patients at the same period, males were about six-year older and both of their hepatitis B surface antigen (HBsAg) and liver cirrhosis positive rates were higher (P＜0.05)， but there were no significant differences of the other clinicopathological parameters between the male group and the female group. Multivariate analysis showed that Edmondson-Steiner grade and portal vein tumor thrombosis (PVTT) were two independent prognostic influencing factors of both the overall survival and the tumor-free postoperative survival of male patients with HCC, while satellite nodule and tumor size only influenced the overall survival. Conclusion The main clinicopathological features and the postoperative survival of male HCC patients were similar than those of female’s. Tumor differentiation and biological behaviors were major factors affecting postoperative survival of male patients with HCC.
Objective To research clinic characteristics, therapies and 2-year progress of female patients with Non-ST-segment Elevation Acute Coronary Syndrome (NSTE-ACS). Methods This study was part of the internationalized Organization to Assess Strategies for Ischemic Syndromes (OASIS) registry. There was no intervention in the therapy. Patients admitted to hospital with NSTE-ACS (including unstable angina and non-Q wave myocardial infarction) were enrolled. The patients’ clinical characteristics, treatment procedure, major events in hospital and two-year progress were recorded by filling in Case Report Forms. Single-variate analyses were made between patients of difference genders. Results A total of 2 294 patients with NSTE-ACS were enrolled in China. The female patients were 37.7% (n=864), whose mean age was 65.1±6.7 years. Unstable angina dominant (90.7%) was noted on admission. The percentage of patients with abnormal ECG was 92.6%. The prior hypertension and diabetes were 64.1% and 23.4%, respectively, in female patients which were evidently higher than those of males (P≤0.001). The prior coronary heart disease, old myocardial infarction, smoking, and percutaneous coronary intervention (PCI) were 39.4%, 16.8%, 11.7%, and 2.3% respectively, in females, which were evidently lower than in males (P≤0.001). The prior history of coronary artery bypass graft (CABG) surgery was 0.5% in females, which was evidently lower than in males (P≤0.05). During hospitalization, the therapeutic rates of anti-platelets and β-adrenergic blockers were 92.8% and 64.8%, respectively, in female patients, which were observably lower than in males (P≤0.05). The therapeutic rates of nitrates, angiotensin-converting enzyme inhibitor (ACEI), calcium antagonists, lipid lowering agents were 96.9%, 60.0%, 59.1%, and 47.1%, respectively, in females, which were not significantly different from those of males. The medication rate in females fell off gradually after discharge, which was more evident than in males. In two-year follow up, the therapeutic rates of anti-platelets, β-adrenergic blockers, ACEI, and lipid lowering agents were 68.4%, 39.5%, 27.4%, and 19.4%, respectively, in female patients, which were markedly lower than those in males (P≤0.05). During hospitalization, the therapeutic rates of PCI and CABG were 10.5% and 2.7%, respectively. In two year follow-up, their therapeutic rates were 13.4% and 4.8%, respectively. The rate of females performing revascularization procedures was evidently lower than that of males (P≤0.001), either during hospitalization or in two-year follow up. In two years of follow up, mortality and incidence rates of new myocardial infarction, stroke, heart failure, hospitalization because of refractory angina were 7.4%, 4.7%, 6.8%, 15.4%, and 31.3%, respectively, in female patients. There were no significant differences between females and males (Pgt;0.05). Conclusion Compared with male patients, female patients with NSTE-ACS are less likely to adopt and / or attach importance to treatment. As to the reason why there are no significant differences in major events of NSTE-ACS between females and males under the current circumstance that females’ treatment is inferior to males’, gender of females is an important protective factor.
Objective To assess the response rate, improvement in neurological function and safety of cinepazide maleate injection for patients with cerebral infarction. Methods Based on the principles and methods of Cochrane systematic reviews, we searched the Cochrane Central Register of Controlled Trials (Issue 1, 2010), PubMed (1948 to March 2010), EMbase (1966 to March 2010) and Chinese Bio-Medicine Database (1978 to March 2010). We also hand searched relevant literatures and obtained unpublished trials from pharmaceutical companies. The Cochrane Collaboration’s software RevMan5.0 was used for meta-analysis. Results Fifteen randomized controlled trials involving 1 456 patients were included. The results of meta-analyses indicated that: 1) Neurological deficits: We identified 11 trials involved 978 patients. Cinepazide maleate injection group compared with the control groups (placebo, Xuesaitong, Dansen and Nimodipine) could significantly improve the neurological deficits. The difference was statistically significant with WMD= – 4.64, 95%CI – 6.43 to – 2.85, WMD= – 2.39, 95%CI – 4.37 to – 0.42, WMD= – 3.67, 95%CI – 5.26 to – 2.07 and WMD= – 6.14, 95%CI – 8.39 to – 3.89, respectively. 2) Response rate: A total of 14 trials involved 1 349 patients were identified. Compared with control groups (placebo, Xuesaitong, Dansen and Nimodipine), cinepazide maleate injection group were more efficient, the difference was statistically significant with RR=1.33, 95%CI 1.16 to 1.54; RR=1.24, 95%CI 1.04 to 1.50; RR=1.33, 95%CI 1.23 to 1.43 and RR=1.29, 95%CI 1.12 to 1.49, respectively. 3) Adverse events: No serious adverse events were observed. But the difference of adverse events reports of headache and skin itching in cinepazide maleate injection group was statistically significant compared with the control groups. Conclusion Current evidence shows that cinepazide maleate injection can reduce neurological deficits in patients with acute cerebral infarction, improve the clinical treatment efficacy without serious adverse events. Due to limited quality of included studies, high-quality, large sample randomized controlled trials are required.
Objective To explore the methods of intervention for street-based female sex workers (FSWs) by assessing the intervention process, and evaluate the effectiveness. Methods By cluster sampling procedure, many streetbased female sex workers in Yuzhong district were intervened systematically after informed consent. Before and after the intervention, questionnaire survey was conducted to understand their KAP towards AIDS and analyzed the results of the questionnaire and the effectiveness of intervention. Results The recognition rate abut AIDS knowledge was improved markedly, from the previous 28% to the later 70.5%; condom use in last act increased the previous 59% to the later 75%, consistent use in recent month changed from 4% to 26%; Peer education was trained. Conclusion systematical intervention among street-based female sex workers is critical for spread of AIDS.
Objective To analyze stress-related disorders and the effect of crisis prevention in 54 females admitted to the Female Psychiatry Department of The Third Hospital of Mianyang City after the Wenchuan earthquake. Methods The patients were assessed with BPRS, HAMD, HAMA, and BPMS scales. According to their clinical manifestations, antipsychiatric, antidepressive, anxiolytic, and antimanic treatment were administered to them. All patients received cognitive-behavior and psychological therapy and were assessed after one month. Results Although all patients were earthquake sufferers, their clinical manifestations varied. Strengthened crisis prevention combined with appropriate drug treatment alleviated their symptoms. Conclusion In terms of alleviating symptoms, curtailing disease course, and facilitating mental rehabilitation, post-catastrophe crisis prevention is extremely important for female patients with stress-related disorders.

Serum total testosterone in the treatment group rose, upper arm circumference and right hand grip improved （P〈0.05 ）. 4. There were no significant differences in adverse effects between both groups. Conclusions TU can improve the clinical health status in the elderly male patients with chronic disease in advanced stage and increase serum testosterone level, there is a satisfactory tolerances and few adverse reactions.
Objective To evaluate the sensitivity， specificity, and accuracy of magnetic resonance imaging （MRI） in characterizing adnexal masses. Methods The databases such as the Cochrane Library, PubMed， EMbase， CNKI， and WanFang Data were searched on computer from 1991 to 2011. The reviewers screened the trials according to inclusion and exclusion criteria strictly, extracted the data， and assessed the methodology quality. Meta-analysis were performed using the Metadisc 1.40 software. The acquired pooled sensitivity, specificity， and summary receiver operating characteristic curve （SROC） were used to describe the diagnostic value. The pooled likelihood ratios were calculated based on the pooled sensitivity and specificity. Results Ten case-control studies involving 649 women who were suspected to have pelvic masses were included and 729 masses were confirmed by the postoperative histopathology. The pooled statistical results of meta-analysis showed that：the sensitivity and specificity of MRI were 〔89%（84%-92%）， P=0.046 6〕 and 〔87% （83%-90%）， P=0.000 2〕 respectively, the positive and negative likelihood ratios of MRI were 6.25（P=0.008 5） and 0.14（P=0.029 1） respectively, and the area under the SROC curve （AUC） was 0.941. The sensitivity and specificity of ultrasound were 〔87%（82%-91%）， P=0.000 0〕 and 〔73%（69%-77%）, P=0.000 0〕 respectively, the positive and negative likelihood ratios of MRI were 3.07（P=0.000 0） and 0.18（P=0.000 1） respectively， and the AUC was 0.897. The speci?city and accuracy of MRI in characterizing female pelvic masses were higher than ultrasound obviously. Conclusion According these evidences， the MRI should be recommended to the women who are suspected to have pelvic masses as a preferred.
