40 patients presenting gastric symptoms underwent gastric mucosa biopsy while doing gastroscopy. All samples were analyzed by Wartin-Stany dying, rapid urase test, and 13C-urea breath test respectively as well as by histological examination. The patients with the same results by WS and RUT were regarded as chronic gastritis. In this patient, we analyzed the specificity, sensitivity and accuracy of 13CUBT.

取40例因上腹部症状而行胃镜检查的患者胃窦粘膜活检，分别行Wartin-Stany银染色、快速尿素酶实验、13C尿素呼气试验（13CUBT），并同时行病理组织学诊断；将WS和RUT结果相一致且病理结果为慢性胃炎的病例入选，分析13C尿素呼气试验（13CUBT）诊断慢性胃炎幽门螺杆菌感染的特异性、敏感性、准确性。

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

The plant community composition changed and the community coverage increased over the wetland succession from primary swamp, through swampy meadow, to meadow. The number of associated species increased, while the dominant species abundances decreased. Through succession, the content of soil organic matter and total nitrogen declined. In contrast, the soil enzyme activity of catalase, protease and invertase increased; however urase declined.

随着湿地原生沼泽向沼泽化草甸、草甸的演替，湿地植物群落盖度增加、物种组成增多，群落优势种优势度减小，伴生种数量增加，植物多样性呈增加趋势；湿地土壤有机质、全氮含量不断减少，过氧化氢酶、蛋白酶、蔗糖酶活性增加，脲酶活性降低。

Morphological and physiological identification showed that NTG-01 was Gram-negative, short rod shape, with flagella around the bacteria, V-P test positive and Methyl red test negative. The bacterium can use glucose as carbon suource and produce gases. No H2S produced on TTS medium. Lysine decarboxylase and orthinine decarboxylase, catalase and gelatine test are positive. Arginine decarboxylase, dehydrolase, oxidase and urase test are negative. Sequencing and alignment of 16S rDNA showed that it shared a 99% homologous sequence with Enterobacter aerogenes.
