Objective:To investigate impact of atractylolidⅠ(ATR-Ⅰ)on liver function of hepatitis B virus(HBV)infection rats by regulating cGAS-STING pathway.Methods:Ten rats were randomly selected as control group(NC),rest rats were injected with HBV antigen via tail vein to construct HBV model.Rats successfully modeled were randomly grouped into HBV group,ATR-Ⅰgroup(50 μg/kg),inhibitor of cGAS-STING pathway(RU.521)group(450 μg/kg),ATR-Ⅰ+RU.521 group(50 μg/kg ATR-Ⅰ+450 μg/kg RU.521),with 10 rats in each group.NC group and HBV group were injected with same amount of normal saline once a day for 1 week.Serum aspartate aminotransferase(AST),alanine aminotransferase(ALT),hyaluronic acid(HA),laminin(LN),procolla-gen type Ⅲ(PC Ⅲ),IFN-γ,IL-2,TNF-α,hepatitis B surface antigen(HBsAg),hepatitis B e antigen(HBeAg)were detected by ELISA;HE staining was applied to detect liver histopathology;Masson staining was applied to detect degree of liver fibrosis;Western blot was applied to detect expressions of cGAS-STING pathway proteins in liver tissue.Results:Collagen volume fraction,ALT,AST,HBsAg,HBeAg contents,HA,LN and PC Ⅲ,IFN-γ,TNF-α and IL-2 levels in HBV group were higher than NC group,levels of cGAS,STING,p-TBK1/TBK1,p-IRF3/IRF3 and IFN-β were decreased(P<0.05);compared with HBV group,degree of liver injury and liver fibrosis in ATR-Ⅰ group were improved,collagen volume fraction,ALT,AST,HBsAg,HBeAg contents,HA,LN,PC Ⅲ,IFN-γ,TNF-α and IL-2 levels were decreased,levels of cGAS,STING,p-TBK1/TBK1,p-IRF3/IRF3 and IFN-β were in-creased(P<0.05),RU.521 group showed opposite trend,RU.521 eliminated improvement effect of ATR-Ⅰ on liver function of HBV rats.Conclusion:ATR-Ⅰmay improve liver function of HBV rats by activating cGAS-STING pathway.

OBJECTIVETo understand the syphilis infection and its high risk factors among men who have sex with men (MSM) recruited from different channels.

METHODSSupported by the China-Gates Foundation HIV program from July to December 2011, we cooperated with community based organizations to conduct syphilis testing intervention among MSM from 14 cities (Beijing, Shanghai, Tianjin, Chongqing, Harbin, Shenyang, Qingdao, Xi'an, Nanjing, Wuhan, Hangzhou, Changsha, Kunming, and Guangzhou) and one province (Hainan province). Participants were recruited from different channels by the staff of local CBOs, Demographic (e.g. age, marital status, and education) and behavioral (e.g. condom use and sexual partners) data were collected using anonymous questionnaires. Blood samples were also collected to test for syphilis. A total of 34 100 MSM participated in the survey. Participants were excluded from data analysis (1 399, 4.1%) if they did not receive syphilis tests or they completed less than 80.00% of the key questions in the survey. Chi-square tests were used to understand the socio-demographic and behavioral differences between each group. Results of syphilis tests were also compared. Logistic regression models were used to test the statistical significance of these differences.

RESULTSA total of 32 701 MSM were enrolled and received syphilis testing. The average age of participates was 30.96 ± 9.57. And among them, 2 284 cases (7.0%) were recruited from gay bathhouses, 4 774 (14.6%) from gay bars, 6 266 (19.2%) from the internet, 1 997 (6.1%) from the parks/toilets and 17 380 (53.1%) from other channels. MSM recruited from the bathhouses had the highest syphilis infection rate than other 4 groups: gaybars (4.5%, 216/4 774), internet (6.7%, 422/6 266), parks/toilets (8.3%, 166/1 997), other channels (6.4%, 1 103/17 380) (χ² = 164.58, P < 0.001). The multivariate logistic regression analysis showed that being > 20 years of age (P < 0.001), having more than 2 homosexual partners in recent 3 months (8.0% (1 408/17 714), OR (95% CI) = 1.44 (1.04-1.98)), having no sex with females in past 3 months (6.8% (1 446/21 276), OR (95% CI) = 1.25 (1.07-1.46)), and not using condom at last anal sex (8.0% (769/9 668), OR (95% CI) = 1.13 (1.03-1.25)) were associated with a higher probability of being infected with syphilis. Whereas MSM married (7.2% (456/6 305), OR (95% CI) = 0.84 (0.73-0.98)), having a college or a higher education (5.3% (829/15 684), OR (95% CI) = 0.60 (0.53-0.67)), being local residents (6.5% (1 843/28 185), OR (95% CI) = 0.73 (0.61-0.87)) and living in the local province of project cities (6.6% (170/2 593), OR (95% CI) = 0.67 (0.53-0.85)) were protective factors.

CONCLUSIONMSM who were recruited from gay bathhouses have a higher rate of syphilis infection than those in channels relatively. They are older, with low education levels and high-risk sexual behaviors. Tailored interventions are required in the future, especially for MSM from gay bathhouses.

Objective To investigate the validity and reliability of the Chinese version HCL-32(CV-HCL-32) in the patients with bipolar disorder(BP) and the best cut-off between the patients with BP and patients with major depression disorder (unipolar depression disorder, UP). Methods The English version HCL-32 was translated into Chinese version after the agreement of the author of the HCL-32. 300 consecutive patients with BP and 156 consecutive patients with UP in outpatients and inpatients departments diagnostically interviewed with DSM-Ⅳ were rated by CV-HCL-32. The test-retest reliability with interval of eight to fourteen days was investigated in 155 patients (51.7%) with BP in the bipolar patients. Results A two-factor solution was preferred by the factors analysis. The Eigenvalues of the two factors were 6.32, 3.00 respectively. The two factors together accounted for 29.1% of the total variance. The internal consistency( Cronbach's alpha) of the CV-HCL-32 was 0.86.The test-retest reliability of the CV-HCL-32 was 0.62(P＜ 0.01 ). The frequency of positive responses to various items ranged from 11.6% to 89.7%. The mean score of CV-HCL-32 was statistically higher in patients with BP( 16.6 ± 6.2) than that of UP ( 10.9 ± 6.4). A CV-HCL-32 screening score of 14 was chosen as the optimal cutoff between the patients with BP and UP, as it provided good sensitivity (0.74) and specificity (0.66). The positive and negative predictive power for this cut-off was 0.81 and 0.57. Conclusions The study demonstrated the suitable validity and reliability of CV-HCL-32, suggested that the CV-HCL-32 is useful questionnaire for screening bipolar disorder in China.
