摘要:   目的 研究γ干扰素 (IFNγ)及I型γ干扰素受体(IFNγR1)在慢性血吸虫病(慢血)及晚期血吸虫病(晚血)患者中表达水平,探讨IFNγ和IFNγR1表达的临床意义及其和肝纤维化的关系。 方法 用流式细胞术检测慢血及晚血患者外周血淋巴细胞IFNγR1的表达水平;用ELISA法检测慢血及晚血患者血清IFNγ水平;用放射免疫法检测血清中透明质酸(HA)、Ⅳ胶原(ⅣC)、层粘连蛋白(LN)、Ⅲ型前胶原(PCⅢ)等肝纤维化指标。采用对比分析,观察IFNγR1、IFNγ及肝纤维化指标在慢血及晚血患者中的表达水平及相关性。 结果 慢血患者IFNγR1和IFNγ与健康对照组比较差异无显著性 (P>0.05);晚血未切脾患者IFNγR1表达明显低于其他组(P<0.05),而IFNγ增高(P<0.01);晚血切脾患者此两项指标又恢复正常;IFNγR1和IFNγ与HA、ⅣC、LN、PCⅢ之间无相关性(r分别为0.19、0.20、0.14、0.21)。结论 IFNγR1和IFNγ之间存在相互对应关系 ,IFNγR1的表达与血吸虫病的病程有关

Abstract: Objective To study the expression of interferonγ(IFNγ) and typeⅠinterferon γ receptor (IFN γR1) in the chronic and advanced patients of schistosomiasis japonica, and to discuss its clinical relationship with hepatic fibrosis. Methods IFN γR1 in the peripheral blood lymphocytes was detected by ELISA, and the hyaluronic acid (HA), collagen type Ⅳ(C Ⅳ), procollagen type Ⅲ (PCⅢ), laminin (LN) were detected by radio immunoassay (RIA) in schistosomiasis patients. The level of IFN γ, IFN γR1 and serum markers of hepatic fibrosis were observed, and the relationship with each other was analyzed by statistical method. Results There was no difference in the expression of IFN γ and IFN γR1 between the patients with chronic schistosomiasis and the normal group ( P>0.05), the IFN γR1 in advanced cases without splenectomy was low ( P <0.05), but IFN γ was high( P<0.01). The two indicators in the advanced schistosomiasis patients with splenectomy returned to normal. There was no corresponding relationship between the two indicators and HA, C Ⅳ,PCⅢ,LN with a r value of 0.19, 0.20, 0.14, and 0.21 respectively. Conclusion There is a corresponding relationship between IFN γ and IFN γR1; the expression of IFN γR1 is related to the course of schistosomiasis, and the relationship with hepatic fibrosis needs further study.
