Objective To explore the clinical value of serum interleukin(IL)-33 and its soluble receptor ST2(sST2) level in patients with chronic hepatitis B.Methods A total of 65 cases with chronic hepatitis B were recruited into study group,meanwhile 60 healthy persons were enrolled in the control group from January 2014 to October 2016 in our hospital.IL-33,sST2 and alanine aminotransferase(ALT) were detected and compared in the two groups.Results The level of IL-33,sST2 and ALT were significant higher than those of the control group(t=6.542,7.218,6.324;P<0.05).IL-33 and sST2 levels in chronic hepatitis B patients with abnormal ALT level were significant higher than those with normal ALT(t=16.328,9.874,P<0.05).Conclusion The detection of IL-33 and sST2 in patients with chronic hepatitis B could help to understand the immune status of patients,and provide a theoretical basis for the treatment of chronic hepatitis B.

Objective To investigate the antigenicity of foreign antigen in recombinant vaccinia virus (VACV) after elimination of B8R,and provide help to improve the efficacy of VACV-based vaccines,and provide guidance for vaccine design.Methods Transfer vector pSC11-OVA was generated,and OVAgene was in,rted into VACV with B8R deletion.The biological characteristics of recombinant VACV was investigated in vitro,and the immune responses against OVA were tested in vivo.Results The plague phenotypes and growth of wcombinant VACV and its parental strains were essentially identical.Cellular immuneresponse against OVA was augmented in mice infected with B8R-deleted recombinant VACV when comparedwith those infected with B8R-intact recombinant VACV.Conclusion Deletion of B8R and insertion of OVAdoes not affect the biological characteristics of VACV.Immunogenicity of exogenous target antigens can beimproved in VACV with B8R deficiency.Deletion of dominant epitopes may provide a vector with more efficiency for vaccines and gene therapy.

【Objective】To observe the effect of Sicaotang Decoction which is mainly composed of kidney-nourishing,toxicity-removing and blood-activating herbal medicines on parameters associated with mesenteric proliferation,fibronectin(FN),and Bcl-2 gene expression in lupus nephritis(LN).【Methods】 Sixty LN patients were equally randomized into two groups.The two groups received treatment with hormones and cyclophosphamide,and group Areceived Sicaotang Decoction additionally.The changes of Bcl-2 and Fas expression in CD4+ and CD8+ of T lymphocyte subtypes,serum fibronectin(FN),serum and urine collagen Ⅳ(CⅣ) as well as score of blood stasis were observed.【Results】Sicaotang Decoction reduced the expression of Bcl-2 and Fas expression in CD4+ and CD8+,relieved the proliferation of mesenteric cells,and decreased Bcl-2 positive rate,serum FN level,serum and urine CⅣ levels and score of blood stasis(P
