OBJECTIVETo study the socio-demographic characteristics, acquired immune deficiency syndrome (AIDS) related behaviors of male clients of female sex workers and their determinants.

METHODSContacting subjects through 5 ways including volunteers of female sex workers (FSWs), sexually transmitted disease (STD) clinics, long-distance bus stations, long-distance cargo station while adopting methods as snowballing, employing an anonymous questionnaire. Data was analyzed by logistic regression analysis.

RESULTS(1) The majority of clients were 25-45 years old, married and of junior high school or above educational levels; (2) Among male clients of FSWs, numbers of having had commercial sexual intercourse was between 1 to 240, averaged 24 in the previous year. It significantly related to their occupation and the experience of their friends or colleagues who ever visited female sex workers; (3) 27.98% of them used condom every time during commercial sexual intercourse, which significantly related to the score of knowledge on AIDS, concourse of sex intercourse and inhabitation; (4) 28.36% of them had ever contracted STD, which significantly related to the frequency of commercial sexual intercourse in the previous year, risk awareness of being infected with human immunodeficiency virus, and frequency of condom use during commercial sexual intercourse.

CONCLUSIONThe proportion of always using condom was low among male clients of FSWs, and had had STDs. And it's necessary for active and specific intervention programs to them.

Objective To explore the effect of Tongdu Tiaoshen acupuncture,a needling method for dredging governor vessel and regulating mind,on cerebral hemodynamics and oxygen free radicals in the patients with post-stroke epilepsy(PSE).Methods A total of 60 patients with PSE were randomly divided into a treatment group and a control group,with 30 cases in each group.Both groups were given basic treatment for lowering lipid level,controlling blood pressure and glucose contents,and counteracting platelet aggregation.Moreover,the control group was treated with Sodium Valproate Sustained-Release Tablets,and the treatment group was treated with Tongdu Tiaoshen acupuncture mainly on the acupoints of Baihui(GV20),Shenting(GV24),Shuigou(GV26),Fengfu(GV 16),Fengchi(GB20)based on the treatment for the control group.One month constituted a course of treatment,and the treatment for the two groups covered three courses of treatment.The number of epileptic seizures,the severity of electroencephalogram(EEG),the peak systolic velocity(Vs)and end diastolic velocity(Vd)of bilateral anterior cerebral arteries,middle cerebral arteries and posterior cerebral arteries detected by transcranial Doppler ultrasonography(TCD),and the changes in the peripheral levels of oxygen free radicals such as malondialdehyde(MDA),hydroxyl radical(OH),lipid peroxide(LPO)and superoxide dismutase(SOD)in the two groups were observed before and after treatment.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After three months of treatment,the total effective rate of the treatment group was 93.33％(28/30),and that of the control group was 73.33％(23/30).The intergroup comparison(tested by chi-square test)showed that the efficacy of the treatment group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the average monthly epileptic seizure frequency in the two groups was decreased when compared with that before treatment(P＜0.05),and the decrease in the treatment group was more significant than that in the control group(P＜0.05).(3)After treatment,the grading of EEG severity in the two groups was significantly improved when compared with that before treatment(P＜0.05),and the improvement in the treatment group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the peripheral levels of oxygen free radicals of MDA,OH and LPO in the two groups were lower than those before treatment(P＜0.05),and the peripheral level of SOD was higher than that before treatment(P＜0.05).The decrease of MDA,OH and LPO levels and the increase of SOD level in the treatment group were significantly superior to those in the control group(P＜0.05 or P＜0.01).(5)After treatment,the values of cerebral hemodynamic indicators of Vs and Vd of both left and right anterior cerebral artery,middle cerebral artery and posterior cerebral artery in the two groups were higher than those before treatment(P＜0.05),and the increase in the treatment group was significantly superior to that in the control group,the differences being statistically significant(P＜0.05).(6)During the treatment,there were no fainting,sticking of needle,bleeding and rash occurring during acupuncture in the two groups,which indicated that the therapy had high safety.Conclusion Tongdu Tiaoshen acupuncture can significantly reduce the seizure frequency of PSE and improve the severity of epileptic EEG.Its therapeutic mechanism may be related with the decrease of the oxygen free radical levels and with the improvement of cerebral hemodynamics.

OBJECTIVETo observe the effect of Huanglian Jiedu IJecoction (HJU) on systemic and vascular immune responses of high fat diet fed apoE deficient (apoE(-/-)) mice.

METHODSEight wild type C57BL6 mice were recruited as the wild type common food group. Totally 24 apoE(-/-) mice were randomly divided into the ApoE'common food group, the ApoE(-/-) hyperlipidemia group, and the ApoE(-/-) hyperlipidemia plus HJD group, 8 in each group. In the present study, the common food mice and high fat fed mice were fed with a chow diet or a high cholesterol diet for 4 weeks. HJD was given to mice in the ApoE(-/-) hyperlipidemia plus HJD group at the daily dose of 5 g/kg by gastrogavage, while equal volume of pure water was given to mice in the rest groups by gastrogavage. Four weeks later, the plasma levels of blood lipids, the ratio of peripheral blood mononuclear cells, and expressions of Toll-like receptor 4 (TLR-4) and CD36 on the monocytes were detected. The pathological changes and expressions of cytokines in local aorta were detected. The plasma cytokine levels in response to lipopolysaccharide (LPS) were analyzed. Results (1) Compared with the wild type common food group, TO, TG, and LDL-O significantly increased in the ApoE(-/-) common food group (P < 0. 05, P < 0.01). Compared with the ApoE(-/-) common food group, TC and LDL-C significantly increased in the hyperlipidemia group (P < 0. 05). There was no statistical difference in each index between the ApoE(-/-) hyperlipidemia group and the ApoE(-/-) hyperlipidemia plus HJD group (P > 0.05). (2) Compared with the wild type common food group, no obvious change of the ratio of peripheral blood mononuclear cells happened, the TLR4 expression level significantly increased in the ApoE'common food group (P < 0. 05). Compared with the ApoE common food group, the ratio of peripheral blood mononuclear cells and the TLR4 expression level significantly increased in the ApoE' hyperlipidemia group (P < 0.05). Compared with the ApoE(-/-) hyperlipidemia group, the ratio of peripheral blood mononuclear cells and the TLR4 expression level significantly decreased. Besides, the CD36 expression level also significantly decreased (P<0.05). (3) After stimulated by LPS for 3 h, compared with the wild type common food group, plasma TNF-ct and IL-b expressions significantly increased in the ApoE(-/-) common food group (P < 0.05). Compared with the ApoE(-/-) common food group, plasma expressions of IL-12, TNF-alpha, MCP-1, and IL-10 increased, but with no statistical difference in the ApoE(-/-) hyperlipidemia group (P > 0.05). After 4-week intervention of HJD, compared with the ApoE(-/-) hyperlipidemia group, the MCP-1 expression was significantly down-regulated, while the IL-10 expression significantly increased, showing statistical difference (P < 0.05). Compared with the wild type common food group, mRNA expression levels of IFN-gamma, MCP-1 , TNF-alpha, IL-10, and IL-1beta significantly increased (P < 0. 05, P < 0.01). Compared with the ApoE(-/-) common food group, not only mRNA expression levels of IFN-gamma, MCP-1, TNF-alpha, and IL-1beta, further significantly increased, but also IL-12, IL-10, and TGF-beta significantly increased (P < 0. 05, P < 0. 01). After 4-week intervention of HJD, compared with the ApoE(-/-) hyperlipidemia group, mRNA expression levels of MCP-1, TNF-alpha, IL-1beta, and IL-12 significantly decreased in the ApoE(-/-) hyperlipidemia plus HJD group (P < 0.05, P < 0.01).

CONCLUSIONSHigh fat diet induced systemic reaction and inflammatory reactions of local vessels. The local inflammatory response of vessels exceeded systemic inflammatory response. Intervention of HJD could attenuate inflammatory response, especially in local arteries. Meanwhile, it enhanced systemic anti-inflammatory reactions.
