慢性萎缩性胃炎癌前病变舌诊检测指标研究

目的：探讨对于慢性萎缩性胃炎癌前病变诊断有意义的舌诊检测指标。方法：对萎缩性胃炎癌前病变患者从舌质、舌苔、舌形、舌下络脉、舌尖微循环、舌苔涂片、舌面pH值、唾液CEA检测等多方面进行对照观察与研究。结果：萎缩性胃炎癌前病变患者的舌象多表现为舌质暗红或青紫瘀斑，舌苔腻，舌有齿痕或裂纹，舌下络脉扭曲、扩张或有瘀点；舌尖微循环观察畸形毛细血管襻增加，襻顶扩张瘀血，渗出明显，血色暗红，血液流态异常；舌苔涂片发现舌上皮细胞表现为过度角化，数量增多，涂片背景脏，并出现较多的白细胞；舌面pH值偏高；唾液CEA明显升高。结论：各指标均具有一定的特征性，但联合检测临床意义较大。

Research of Diagnosis Index of Tongue Inspection in Precancerous Chronic Atrophic Gastritis

Objective:To study the indexes of tongue diagnosis in precancerous chronic atrophic gastritis (CAG).Methods:Tongue inspection of Patients with precancerous CAG were carried out including tongue proper,tongue coating,tongue shape,sublingual vena,tongue tip microcirculation,tongue coating smear,PH value of tongue surface and CEA inspection of saliva.Results:It was found that the tongue picture of patients with precancerous CAG showed dark red or purple in tongue proper,greasy fur, indented margin or crack on tongue,twist,extension or with petechiae on sublingual vena.Added macrocephalic capillary Ioops were observed in the tongue tip microcirculation with extension and blood stasis,obvious effusion,dark red blood and abnormal bloodflow pattern on their tops.Increased amount of hyperkeratosis of epidermal cells were observed on tongue coating smear,with dirty background and more white cells.The PH value of tongue surface was a little high and the CEA of saliva significantly improved.Conclusion:Each index has some character to CAG.However the comprehensive inspection has more clinical significance.
