Objective To study the induction of imiquimod on interferon-gamma (IFN-γ) in the peripheral blood of patients with condyloma acuminatum. Methods Twenty-two adult patients with condyloma acuminatum and twenty health control were sequentially enrolled in this study. Serum levels of IFN-γmRNA were measured by realtime polymerase chain reaction in 22 cases with condyloma acuminatum before and after treatment with imiquimod for 8 weeks and 20 health control. Results The serum level of IFN-γ mRNA before treatment was significantly lower than that of health control (t = - 2.87, P = 0.0071). Expression of serum IFN-γmRNA in condyloma acuminatum was significantly increased after 8 weeks imiquimod treatment (t = - 2.51 ,P = 0.0159). The serum level of IFN-γmRNA had no significant difference compared with after treatment group and health control group (t = - 1. 07, P =0. 2922). Conclusion Imiquimod could increase the low expression of IFN-γ mRNA in patients with condyloma acuminatum.

Objective To evaluate the therapeutic effects of taurine combined with silybin meglumine in patients with non-alcoholic steatohepatitis (NASH). Methods One hundred patients with NASH were divided into two groups with 50 for each. The patients in the control group received polyene phosphatidyl choline (456 mg) combined with silybin meglumine (100 mg) 3 times daily for 24 weeks. While those in the treatment group received taurine (2 g) combined with silybin meglumine (100 mg) 3 times daily for 24 weeks. All patients were asked to take up basic therapy including drinking without alcohol, restricting sugary and fatty intake, improving food structure, carrying moderate aerobics and lightening body weight. Results At the end of 24 weeks, the clinical symptoms and the liver function ameliorated in two groups. Ultrasonic or CT examination showed that the steatohepatitits was improved significantly in two groups. Additionally, the levels of blood glucose, serum triglyceride and cholesterol as well as BMI decreased simultaneously (all P value <0. 05). Whereas the treatment group was superior to control group in aspect of amelioration of inappetite, nausea and vomiting as well as lever of serum triglyceride (all P value <0. 05). There was no side effect in the treatment group. Conclusion Based on the basic therapy, taurine combined with silybin meglumine can mitigate the degree of NASH, improve the metabolism of blood glucose and lipid with few side-effects.

Objective To determine the key interventions transferring from the control to elimination of malaria in China so as to provide the basic information for achieving malaria elimination. Methods Based on the data collected from the document entitled of The National Annual Report on Schistosomiasis,Malaria and Echinococcosis,published by the National Institute of Parasitic Diseases of Chinese Center for Disease Control and Prevention,the malaria incidence and intervention data were se?lected only in the typical endemic provinces during the period of 2004-2010. The correlation between the incidence and interven?tions in the target provinces was analyzed based on the Panel Data Regression Model,and the key interventions were deter?mined. Results Four provinces namely Anhui,Yunnan,Hainan and Henan were targeted with 87.56%of the national malaria figures from 2004 to 2010. When Y was given as vivax malaria incidence,X1 as the log of the number of historical cases receiving radical treatment in the pre?transmission stage(RTPT)(F=14.53,P<0.01,R2=0.72),X2 as the log of risk population receiv?ing RTPR(F=15.90,P<0.01,R2=0.71)and X3 as the number of technicians trained in microscopy(F=11.53,P<0.01,R2=0.61),three space?fixed effect models were established respectively,and X1,X2,as well as X3 had negative effects on Y value. When Y was given as falciparum malaria incidence,X1 as the accumulated technicians trained in microscopy(F=11.06,P<0.01,R2=0.87),X2 as the log of technicians trained in entomology(F=15.28,P<0.01,R2=0.89),two two?way(space and time)fixed effect models were established respectively,and both X1 and X2 had negative effects on Y value. Conclusion RTPT among historical patients and at?risk populations as well as microscopy training influences the variation of vivax malaria inci? dence,while the significant interventions of microscopy training and vector control training indicate that the integrated measures with strengthened capacity in diagnosis and vector control are of importance in the control of falciparum malaria transmission.

Objective To explore the association between inflammatory cytokines and islet β-cell function in chronic persistent asthma patients. Methods 112 adults with persistent asthma and 60 healthy volunteers were enrolled in this study. According to the severity of disease, all subjects were divided into persistent-mild group and persistent-moderate group. Plasma tumor necrosis factor-α(TNF-α), interleukin6(IL-6) and C-reactive protein (CRP) were determined. Oral glucose tolerance and insulin releasing test were performed. The ratio of the area under the curve of insulin to area under the curve of glucose ( AUC1/AUCG ), homeostasis model assessment for insulin resistance ( HOMA-IR), insulin sensitivity index( ISI),homeostasis model assessment for β-cell function (HBCI) and early insulin secretion index(△I30/△G30)were calculated. The values of forced expiratory volume in l second ( FEV1 ), forced vital capacity(FVC)and FEV1/FVC were recorded. Results In patient groups, the values for plasma TNF-α, IL-6, CRP,AUC1, AUC1/AUCG, HOMA-IR, HBCI significantly increased compared with those in control group, while ISI declined ( t =2. 02~13.62, P <0. 05). Multiple step regression analysis showed that HOMA-IR was positively correlated with CRP, LDL-C, BMI, AUC1, TNF-α( P <0. 01 orP <0. 05), but negatively correlated with FEV1 ( P < 0. 05 ). Conclusion The results indicated that inflammatory cytokines ( TNF-α,IL-6,CRP) might result in insulin resistance in asthma patients who had hyperinsulinism at the same time.
