Aspirin or celecoxib can inhibit the growth, urease activity and vacuolating cytotoxin activity of H pylori in vitro significantly.

阿司匹林及塞莱昔布可剂量依赖性的抑制 H pylori 的尿素酶活性及空泡毒素的活性。

Methods: A polymerase chain reaction assay with oligonucleotide primers homologous to a portion of the urease C and cytotoxin associated gene A of Hp was used to test the presense of Hp in dental plaque.

依据特异的尿素酶C 基因和 cag A基因设计引物，建立聚合酶链反应方法，检测65例慢性胃病患者不同牙齿的龈上和龈下菌斑中的Hp.6例胃Hp阳性的胃炎患者，经药物治疗后，检测口腔Hp。

HP were determined by rapid urease test,Warthin-Starry silver stain and polyme rase chain reaction,and expression of P21,P53,C-myc and C-erbB-2 were detecte d by immunohistochemicology (Streptaovidin/Peroxidase,SP) method,and were evalua ted with positive expressive integrality,the mean optical density an d the integral optical density in computer assisted image analysis system.

Objective To establish an effective method for purificating recombinant HspA-UreB fusion protein of Helicobacter pylori from inclusion body.

目的：建立一种有效的纯化幽门螺杆菌热休克蛋白A亚单位-尿素酶B亚单位融合蛋白包涵体的方法。

Objective To explore the clinical value of the titer of serum HP antibody in patients with gastric diseases.Methods Serous HP antibody was detected with ELISA and HP was cultured,tested with urase,and stained with Gram method on smears which was observed microscopically and compared with proteus protein-enveloped test.Results ELISA showed high sensitivity and specificity.Conclusion Serous ELISA detection of HP antibody can be used widely in clinical diagnosis and epidemical screening without endoscopy and biopsy.

目的 探索胃部疾病患者血清中的幽门螺旋菌HP抗体滴度的临床价值方法应用酶联免疫吸附试验ELISA法检测HP抗体与HP培养，尿素酶试验和涂片革兰氏染色作镜下形态检查相比较，并同时与变形杆菌蛋白包被测定法作比较结果显示该法具有敏感特异性强的特点结论该法无需常规内镜检查，活检查HP而单纯用血清学检查，可广泛应用于临床诊断和流行病学人群普查
