This review article compared the antiviral therapies recommended by major international and national guidelines for management of chronic hepatitis B(CHB)issued by American Association for the Study of Liver Diseases, Asian-Pacific Association for the Study of the Liver,Chinese Society of Hepatology & Chinese Society of Infectious Diseases,China Medical Association,and World Health Organization in 2015. The essentials and highlights of guidelines were compared,focusing on goals of therapy,indications of therapy,choices of drugs,endpoints and duration of therapy, management of treatment failure,treatment of CHB in pregnancy.

Data is the basis and soul of clinical trials. To obtain accurate data, strict and standard data management is essential, which can be effectively supported by quality control in statistical analysis. In this paper, we briefly introduce the concept of the quality control in clinical trials, and describe its contents and methods. We hope that this work will be helpful to the application of statistical quality control in data management of clinical trials.

Objective To study the effects of total saponins of Chaenomeles speciosa on release of β-hexosaminidase from rat basophilic leukemia-2H3 ( RBL-2H3 ) mast cells. Methods After rat RBL-2H3 mast cells were prepared, total saponins of Chaenomeles speciosa and the RBL-2H3 mast cells were co-cultured.The toxic effects of total saponins of Chaenomeles speciosa on mast cells were detected by MTT method, β-hexosaminidase release rate was measured by fluorescence quantitative spectrophotometric method, and cell supernatants of tumor necrosis factor-α( TNF-α) release were detected by ELISA. Results After total saponins of Chaenomeles speciosa were co-cultured with RBL-2H3 mast cells with different antigen stimulation, β-hexosaminidase release rates and the levels of TNF-α of mast cells significantly decreased compared with the control group. Conclusion Total saponins of Chaenomeles speciosa inhibit the degranulation of RBL-2H3 mast cells in a dose dependent manner, which provids basis for studying mechanism of inhibiting allergic reactions.

Objective To investigate the relationship between interleukin-17 (IL-17) and vitiligo.Methods Totally,32 vitiligo patients and 30 healthy human controls were enrolled in this study.Blood samples were collected from all the subjects,and enzyme-linked immunosorbent assay (ELISA) was performed to determine the plasma levels of IL-17.The relationship of plasma IL-17 levels with disease stage,clinical course and lesion area was assessed.Results The plasma levels of IL-17 were significantly higher in the patients with progressive and stable vitiligo than in the healthy controls (both P ＜ 0.05),and higher in the patients with progressive vitiligo than in those with stable vitiligo (P ＜ 0.05).Moreover,the plasma levels of IL-17 were positively correlated with the area of vitiligo lesions (r =0.456,P ＜ 0.05),but unrelated to the clinical course of vitiligo (r =0.239,P ＞ 0.05).Conclusion IL-17 may play a certain role in the occurrence and development of vitiligo.

Objective To explore the risk factors affecting prognosis of invasive fungal infection .Methods The clinical data of 208 hospitalized patients diagnosed with invasive fungal infection in Sun Yat-sen memorial hospital from 2007 to 2011 were reviewed . The factors affecting prognosis were determined by univariate and logistic regression analysis .Results The fatality rate of adult inpa-tient with invasive fungal infection was 21%.The univariate analysis showed that difference of seven indicators was significant between the survive group and death group:advanced age (over 60 years old), hospitalization time,fasting plasma glucose level, hypoalbumin-emia, using more than two kinds of broad spectrum antibiotic for more than two weeks , kinds of invasive operations , and multiple organ dysfunction syndrome ( MODS) .Binary logistic regression showed that the difference of five indicators was significant between the two groups:advanced age (over 60 years old), hypoalbuminemia, using more than two kinds of broad spectrum antibiotic for more than two weeks, kinds of invasive operations , and multiple organ dysfunction syndrome .Conclusions The indicators such as advanced age (over 60 years old), hypoalbuminemia, the use of more than two kinds of broad spectrum antibiotic for more than two weeks , kinds of invasive operations , and multiple organ dysfunction syndrome might be independent risk factors of death in patients with invasive fungal infection.Early medical intervention should be made in clinical work , in order to reduce fatality rate of patients with invasive fungal in-fection.
