和解法为主对溃疡性结肠炎患者TNF—α、IL—8和sIL—2R含量调节作用的研究

目的：观察和解法方药治疗效果及探讨和解法为主对溃疡性结肠炎患者的作用机制，为临床用药提供依据。方法：采用和解法方药对30例溃疡性结肠炎患者进行了临床观察，并与西药对照组比较，采用双抗体夹心ELISA法，对和解法方药治疗前后的溃疡性结肠炎患者的TNF－α、IL－8和sIL-2R含量进行了检测。结果：和解法为主中药疗效明显优于西药对照组（P＜0．05），能调节溃疡性结肠炎患者TNF－α、IL－8水平，使其恢复正常状态，但sIL-2R水平未能达到正常。结论：和解法为主治疗溃疡性结肠炎疗效显著，并为预防复发应长期巩固治疗，其作用与调节免疫功能有关。

Protein P37 of mycoplasma hyorhinis induces secretion of TNF-α from human peripheral blood mononuclear cells

High mycoplasmal infection ratio in gastric cancer tissues suggests a possible association between my-coplasma infection and tumorigenesis.Because TNF-α plays an important role in carcinogenesis caused by microbes in-fection and P37 is a major immunogen of mycoplasma hy-orhinis(M.hyor.),investigating whether P37 could induce expression and secretion of TNF-α will be very significant fo elucidate the possible molecular mechanism of gastric car-cinogenesis involved with M.hyor.At the present study,we cloned full gene of p37 by PCR and mutated the 7 codes of TGA into TGG firstly,then expressed the P37 protein suc-cessfully with pGEX-4T-1 vector in E.coli,which was veri-fied with Western bolt.By RT-PCR and sensitive L929 cell toxic assay,we found that P37 protein could induce expres-sion and secretion of TNF-α from human peripheral blood mononuclear cells,and the inducing activity of P37 could be dramatically blocked by McAb PD4.These results suggest that the induction of TNF-α secretion by P37 probably plays an importan role in diseases caused by M.hyor.infection and needs to be further investigated.
