目的：探讨胃炎消逆转胃癌癌前病变(PL GC)的作用机制。
Objective: To explore the acting mechanism of Weiyanxiao (WYX) in the treatment of precancerous lesions of gastric cancer (PLGC).
上皮内瘤变作为胃癌的癌前病变，其进展至胃癌的概率不一，但高级别上皮内瘤变与胃癌的关系密切。
The intraepithelial neoplasia is the precancerous lesion of gastric cancer, which may develop to gastric cancer, but the probability varies.
因此，MCM5可以作为癌前病变及胃癌诊断的有效标志物。
Therefore, MCM5 can serve as an effective marker for the diagnosis of precancerous lesion and gastric carcinoma.
方法：采用免疫组织化学sp方法对57例胃癌组织、32例癌前病变和对照组20例正常胃黏膜进行MCM5表达的检测。
Methods: Immunohistochemistry SP method was used to detect expression of MCM5 in 57 cases of gastric carcinoma, 32 cases of precancerous lesion and 20 cases of normal gastric mucosa.
