慢性胃炎患者舌象与细胞凋亡的相关性研究

目的：探讨慢性胃炎不同舌象、舌上皮细胞凋亡特征及其形成机理。方法：选择109例慢性浅表性胃炎患者作为观察对象，采用舌象、舌上皮细胞凋亡指数(AI)、凋亡基因相关蛋白p53、Bcl-2和Fas等为指标进行观察。结果：(1)不同舌质和舌苔的AI差异显著；分别以淡白舌与薄白苔和白厚苔为最高。(2)不同舌象的p53、Bcl-2和Fas表达阳性率，呈现相应的变化。相关蛋白表达不仅与舌色有关，而且与舌苔颜色和厚度有关。结论：舌象形成与细胞凋亡具有密切关系，p53、Bcl-2和Fas参与了细胞凋亡的调控，共同构成了本病舌象形成的细胞学基础。

Study on Relationship between Tongue Picture and Cell Apoptosis in Patients with Chronic Gastritis

Objective: To study the characteristics of cell apoptosis in patients of chronic gastritis with different tongue pictures and its mechanism of formation. Methods: The tongue picture, apoptosis index (AI) of lingual epithelial cells, apoptosis related gene proteins, such as p53, Bcl-2 and Fas in 109 patients of chronic superficial gastritis were observed. Results: AI was different in patients with different tongue proper and tongue coating, those with pale white tongue and white thick coating had the maximum value of AI. (2) The p53, Bcl-2 and Fas expression positive rates in patients with different tongue pictures had corresponding changes, which were related not only with color of tongue, but also with color and thickness of tongue coating. Conclusion:The formation of tongue picture is closely related with cell apoptosis, p53, Bcl-2 and Fas take part in the regulation of cell apoptosis, which constitute together the cytologic basis of tongue picture in the disease.
