目的 探讨燥湿和胃方对脾胃湿热证大鼠HPA轴、炎症因子及免疫功能的影响。方法 采用"环境因素+肥甘饮食+致炎因子"的方法复制脾胃湿热证动物模型。SPF级SD大鼠,♂,随机分为6组,即正常组,模型组,三九胃泰组,燥湿和胃方高、中、低剂量组(4,2,1 g·kg-1),每组10只。采用放射免疫法检测促肾上腺皮质激素释放激素(corticotropin releasing homone,CRH)、促肾上腺皮质激素(adrenocorticotropic hormone,ACTH)、皮质醇(cortisol,Cor)的含量;采用免疫组化法检测大鼠胃黏膜组织中环氧合酶-2(cyclooxygenase,COX-2)表达水平;采用ELISA法检测肿瘤坏死因子-α(TNF-α)、白介素1β(IL-1β)、干扰素-γ(interferen-gamma,IFN-γ)、白介素4(IL-4)含量。结果 与正常组相比,模型组大鼠血清中CRH、ACTH、Cor、TNF-α、IL-1β、IFN-γ、IL-4、IFN-γ/IL-4值明显升高(P<0.05)。与模型组比较,燥湿和胃方各剂量组均显著降低大鼠血清中上述指标的含量(P<0.05)。与燥湿和胃方高剂量组相比,低剂量组大鼠血清中CRH、ACTH、Cor含量明显较高(P<0.05);中剂量组大鼠血清CRH、ACTH、Cor含量稍高,但差异没有统计学意义,IL-1β、IL-4与其相当,差异没有统计学意义,TNF-α、COX-2的改善程度明显较弱(P<0.05),IFN-γ、IFN-γ/IL-4值均明显偏高(P<0.05)。结论 燥湿和胃方能有效改善脾胃湿热模型大鼠的疾病活动状态,该作用的发挥可能与调整HPA轴CRH、ACTH、Cor的含量有关,可能通过降低HPA轴相关指标,降低机体炎症反应,改善免疫状态,恢复免疫系统Th1/Th2的动态平衡。 相似文献

Objective To investigate the association between CYP1A1 gene polymorphisms and susceptibility of nasopharyngeal carcinoma in Cantonese nuclear families through family-based association study. Methods A total of 457 Cantonese nuclear families, consisting of 2134 members, were recruited as subjects. Each family included two parents and at least one offspring with nasopharyngeal carcinoma. Two single nucleotide polymorphisms (SNP) in CYP1A1 named m1 (rs4646903) and m2 (rs1048943) , were genotyped by PCR-RFLP assay and verified by directly sequencing. The genotype data were analyzed with family-based association test (FBAT) software to check the linkage and association between the two genetic markers and susceptibility of nasopharyngeal carcinoma. Results FBAT analysis showed that the minor allele frequencies (MAF) of the two SN P were 0. 442 (C) and 0. 339 (G) respectively. For m1 polymorphism in CYP1A1 gene was not significantly associated with nasopharyngeal carcinoma in our study population whether stratified with VCA-IgA or not (without stratification : X2=2. 399, P=0. 301 ; with stratification : Iow-titer group (VCA-IgA<1 : 80), MAF=0. 457 (C), X2=1.221, P=0.543 ; high-titer group (VCA-IgA ≥1 : 80), MAF=0. 427 (C), X2=2. 832, P=0. 243). For m2 polymorphism, when VCA-IgA<1 : 80, the G allele showed decreased transmission under additive and dominant model (MAF=0. 347 (G) ; Zadditive=-2. 120,Padditive=0. 034;Zdominant=-2. 303,Pdominant=0.021)and a boundary P value was got with global statistic (X2=5. 394, P=0. 067). Haplotype TG (0. 057), constructed by ml and m2, might decrease nasophargneal carcinoma risk (Z=-2. 002,P=0. 045). A boundary P value was also got with global statistic (X2=7. 067 ,P=0. 070). Conclusion There was no statistical significance between ml polymorphism and susceptibility of nasopharyngeal carcinoma in Cantonese nuclear families. And this study showed that m2 polymorphism might associated with the decrease of nasopharyngeal carcinoma in Cantonese nuclear families. 相似文献
