免疫缺陷宿主中的感染问题

兔疫缺陷可分为先天性和后天获得性两大类,临床上以后者较为多见。由于免疫缺陷,此类患者易遭受各种感染,常为死亡的主要原因。感染因子包括细菌、真菌、病毒和原虫等,其发病率因原发病而异,感染的临床表现亦与通常所见者不同,因此,对免疫缺陷宿主(简称CH)中感染的诊断、治疗和预防便成了现代医学的重要课题。     

缓症链球菌中毒性休克综合征的临床研究

目的：研究缓症链球菌中毒性休克综合征（TSS）的临床特征及致病机理。方法：对178例重症类猩红热进行临床观察,并对咽拭子培养菌株应用新西兰兔作动物实验,进行毒素分离鉴定。结果：本组病例临床特征为突起畏寒、高热,猩红热样皮疹,不同程度的休克,多脏器功能受损。大多数病人咽拭子培养有α-溶血的缓症链球菌生长,此菌株产生一种分子量为34KD新的致热性外毒素。结论：缓症链球菌可致中毒性休克综合征。     

Expression of type Ⅰ interferon in monocyte-derived dendritic cells after Toll like receptor 3 triggered in patients with chronic hepatitis B

Objective To detect the expression of type Ⅰ interferon in monocyte-derived dendritic cells(MoDCs)after Toll like receptor(TLR)3 triggered in patients with chronic hepatitis B(CHB),and to evaluate immune responses of CHB patients and its roles in the mechanisms of persistent infection of hepatitis B virus(HBV)and chronicity of hepatitis.Methods Peripheral blood mononuclear cells(PBMCs)were isolated and purified using magnetic beads(plasma was saved simultaneously)from 26 CHB patients and 18 healthy volunteers(HV).Dendritic cells(DCs)were induced and proliferated in a culture medium with recombinant human granulocyte macrophage colony stimulating factor(rhGM-CSF)and recombinant human interleukin(rhIL-4).EX3s were stimulated with Poly Ⅰ:C and the supernatants were collected at 0 h and 24 h after stimulation.Type Ⅰ interferon(IFN-α and IFN-β)in plasma and supernatants were examined by enzyme linked immunosorbent assay (ELISA).Results The levels of type Ⅰ interferon in plasma were not significantly different in groups of HV and CH B.IFN-α and IFN-β expressions in supernatants before Poly Ⅰ:C stimulation were(80.00±16.15)ng/L,(36.39±13.90)ng/L in CHB group and(76.76±15.90)ng/L,(37.14±13.68)ng/L in HV group,respectively.And there were no statistical differences between two groups(t=1.651,t=0.178;both P＞0.05).IFN-α expressions in supernatants at 24 h after stimulation in two groups were both higher than those before stimulation(at 0 h),but there were no statistical differences(t=1.534,t=1.243;both P＞0.05).IFN-β expressions in supernatants at 24 h after stimulation in HV group was(54.57±16.80)ng/L,which was significantly higher than that at 0 h(37.14±13.68)ng/L(t=4.061,P＜0.05).However,there was no significant difference at 24 h than tht at 0 h in CHB group(t=1.796,P＞0.05).At 24 h after stimulation.IFN-β level was(54.57±16.80)ng/L in HV group,which was significantly higher than that[(41.64±12.57)ng/L]in CHB group(t=2.921,P＜0.05).Conclusions Functions of MoDCs from CHB patients are impaired and MoDCs could not express type Ⅰ interferon normally.Expression of type Ⅰ interferon after TLR3 triggered in CHB patients is mainly IFN-β.     

汉坦病毒汉城型浙37株G1、G2包膜糖蛋白基因重组体的构建及在真核细胞中的表达

目的：构建汉坦病毒浙37（Z37）株包膜糖蛋白基因G1、G2真核表达质粒，并在真核细胞中表达。方法：根据Z37M基因序列设计6条引物，分别以质粒pGEMZ37,pCUMZ37为模板，通过聚合酶链反应（PCR）获得G1及G2片段。将G1、G2片段经BamHⅠ、XhoⅠ双酶切片插入至真核表达载体pcDNA3.1( ），经酶切鉴定，并测序证实。以磷酸钙沉淀法分别将重组质粒转染COS－7细胞，用间接免疫荧光法（IFA）检测瞬时表达的蛋白。结果：获得分别含有编码汉坦病毒（HV）Z37株包膜糖蛋白G1、G2基因的重组质粒pcDNA3.1-g1,pcDNA3.1-G2；在转染的COS－7细胞内，用IFA可检测到细胞内有特异性荧光。结论：成功地构建了HV Z37株包膜糖蛋白G1、G2基因真核表达载体，并可在COS－7细胞中瞬时表达。
