RT-PCR was used to detect expression level of VP16 mRNA and IFN-gamma mRNA in Herpes simplex virus type-1 infected mice brains at 4th day, 7th day, 10th day, 14th day, 21st day post infection and investigate the effects of the Gardenia extracts-T9 on viral replication and host immunity. The results showed that expression of VP16 mRNA in Gardenia extracts-T9 high dose and low dose group were both lower than that in virus control group at same time point. Relative VP16 mRNA expression in low dose group decreased at 21st day and relative VP16 mRNA expression in high dose group decreased continuously. Relative expression of IFN-gamma mRNA in high dose and low dose groups were both higher than that in virus control group at all time point except the 4th day. IFN-gamma mRNA in low dose group increased from the 4th day till the 14th day, and after the 14th day, the expression decreased slightly. Relative IFN-gamma mRNA in high dose group maintained increasing from 4th day till 21st day. Base on these results, we conclude that Gardenia extracts-T9 might exert the inhibition effect of viral replication by upregulating expression of IFN-gamma mRNA.

Objective Data from the HIV/AIDS surveillance sentinel sites was used to identify the recent HIV-1 infections and to estimate the HIV-1 incidence and epidemic trends among intravenous drug users (IDU),MSM,female sex workers and men attending the sexually transmitted disease clinics in Sichuan province.Methods Specimens collected from IDUs,MSM,female sex workers and men attending the sexually transmitted disease clinics sentinel sites were confirmed as HIV-I positive and tested with BED-CEIA.Annual HIV-1 prevalence and incidence rates were calculated and the incidence was adjusted by McNermar method.Results A total number of 194 223 serum specimens were collected and HIV antibody tested,with 5 297 HIV-1 positive.4 640 of the positives underwent BED-CEIA,with 749 identified as recent infections.During 2011-2015,HIV-1 incidence rates of the four types of population appeared as 5.16％ (95％CI:4.65-5.66),0.22％ (95％CI:0.16-0.28),0.57％(95％CI:0.45-0.69),7.53％ (95％CI:6.06-9.01) and 0.44％ (95％CI:0.36-0.53) respectively.Significant differences were seen in the HIV-1 incidence rates.Conclusions The HIV-1 incidence rates of IDUs from other sentinel sites in Sichuan province,female sex workers and men attending the sexually transmitted disease clinics appeared low,showing that the AIDS prevention and control activities worked effectively.However,the HIV-1 incidence of MSM was still at high level and even rising,suggesting that HIV-1 transmission between MSM and IDUs was possible.

OBJECTIVETo access the prevalence rates of pre-hypertensive patients at different stages and its associated risk factors among adults of Zhejiang province.

METHODSStudy subjects were selected among local residents aged ≥ 18 years from 15 counties by multi stage stratified cluster random sampling method, from July to November, 2010. Each participant was required to complete questionnaire, physical examination and testing for overnight fasting blood specimen.

RESULTS17 437 residents were surveyed including 8169 males and 9268 females. The overall prevalence of prehypertension was 34.39%. The prevalence of pre-hypertension appeared to be higher in males (38.57%) than in females (30.70%) (χ(2) = 119.36, P < 0.0001). The prevalence of pre-hypertension decreased with the increase of age in males who were above 25 year olds (χ(2) = 76.94, P < 0.0001) and in females who were above 45 year olds (χ(2) = 114.66, P < 0.0001). The prevalence of pre-hypertension appeared to be higher in the rural (35.60%) than in the urban (32.39%) areas (χ(2) = 18.69, P < 0.0001). Data from multivariable logistic regression showed that factors as being male, aged older than 35 years of age, with waist circumference as ≥ 85 cm for men and ≥ 80 cm for women, body mass index ≥ 25.0 kg/m(2) and triglyceride ≥ 1.7 mmol/L were risk factors of pre-hypertension while having had higher education was a protective factor.

CONCLUSIONPre-hypertension was prevalent among adults residents in Zhejiang province. Factors as overweight, obesity, dyslipidemia appeared to be major risk factors for pre-hypertension.
