脑卒中的危险因素分析及其与ACE基因的关系

目的：为分析脑卒中的危险因素及其与血管紧张素转换酶插入／缺失（ＡＣＥＩ／Ｄ）多态性的关系。方法：用ＰＣＲ方法分析１１７例脑缺血、１９例脑出血ＡＣＥＩ／Ｄ多态性和１００例原发性高血压患者。用ＳＡＳＳ分析软件分析脑卒中的危险因素。结果：ＤＤ基因型频率和Ｄ等位基因频率比较：脑卒中组显著高于正常对照组;有脑卒中家族史脑缺血患者显著高于无家族史者。高血压组与正常对照组相比,无显著差别。脑出血组的高血压的发生     

高血压性心脏病抗G-蛋白偶联β_1-肾上腺素能受体与M_2-胆碱能受体自身抗体的初步研究

目的抗心肌β１和Ｍ２的自身抗体是否与高血压性心脏病有关。方法以心脏Ｇ－蛋白偶联受体β１和Ｍ２细胞外第二环表位肽段的合成肽作为抗原，应用酶联免疫吸附测定（ＥＬＩＳＡ）技术检测４４例高血压性心脏病（ＨＣＤ）患者、３６例单纯性高血压患者和４１例正常人（对照组）血清中抗β１和Ｍ２受体的自身抗体。结果抗心肌β１受体自身抗体的检出率，高血压性心脏病患者为４７．７％（２２／４４），显著高于高血压患者１１．１％（４／３６）与正常人１２．１（５／４１）；抗心肌Ｍ２受体自身抗体的检出率，高血压性心脏病患者为４５．５％（２０／４４），显著高于高血压患者８．３％（３／３６）与正常人９．８％（４／３６）。高血压性心脏病患者血清中抗β１和Ｍ２受体的自身抗体滴度分别为１∶９６与１∶１０３，远高于单纯性高血压和对照组的１∶４０与１∶２４的相应抗体滴度（Ｐ＜０．０５）。结论高血压性心脏病患者不仅存在抗心肌β１和Ｍ２受体的自身抗体而且其抗体滴度也明显高于单纯性高血压及正常人，检测该抗体对预测原发性高血压患者是否并发心肌病变，可能有一定的参考价值。     

AN ASSOCIATION STUDY BETWEEN ESSENTIAL HYPERTENSION AND HLA-DRB1 ALLELES

It is well established that genetic and environmental factors are involved in the etiology of essential hypertension(EH), previous studies have suggested that at least one of the HLA genes is responsihle for the genetic susceptlbility to EH. Our aim in the present study was to investigate this issue in China by the PCR-SSP HLA-DRB1 typing method. The resuks showed an increased frequency of HLA-DR2 and a decreased frequency of HLA-DR7 with EH patients compared with controls. We consider that HLA-DR2 may represent a marker for susceptibility to EH in the North Chinese popuhtlon.
