胃癌患者舌下络脉的临床观察

Clinical observation of sublingual vessel in patients with gastric cancer

目的探讨胃癌患者舌下络脉的特点,分析舌下络脉与胃癌诊断的相关性。方法本研究收集2020年1月—2021年1月就诊于浙江省杭州市余杭区中医院的慢性非萎缩性胃炎患者81例和慢性萎缩性胃炎患者111例,同期就诊于浙江省肿瘤医院的胃癌患者204例。观察并记录三组舌下络脉的相关信息,包括长度、粗细、形态、色泽及瘀点瘀斑,并基于人工智能舌诊辨识系统对舌下络脉瘀阻程度进行定量分析。结果三组舌下络脉分级水平比较,差异有统计学意义(P<0.05),其中,胃癌组舌下络脉分级水平高于慢性非萎缩性胃炎组和慢性萎缩性胃炎组,差异有统计学意义(P<0.05);慢性萎缩性胃炎和慢性非萎缩性胃炎组舌下络脉分级比较,差异无统计学意义(P>0.05)。早期胃癌患者舌下络脉分级优于晚期患者,差异有统计学意义(P<0.05)。结论舌下络脉的分级可以作为胃癌临床诊断的参考指标之一,提示舌下络脉与胃癌的发生发展存在一定联系。

Objective To investigate the characteristics of sublingual vessel in patients with gastric cancer and to analyze the correlation between sublingual vessel and gastric cancer diagnosis.Methods This study collected 81 patients with chronic non-atrophic gastritis and 111 patients with chronic atrophic gastritis who visited Yuhang District Traditional Chinese Medicine Hospital of Hangzhou City,Zhejiang Province from January 2020 to January 2021,and 204 patients with gastric cancer who visited Zhejiang Cancer Hospital during the same period.The information of three groups of sublingual vessel was observed and recorded,including length,thickness,shape,color,petechia,and ecchymosis.The degree of sublingual vessel stasis was quantitatively analyzed based on artificial intelligence tongue diagnosis and identification system.Results There was significant difference in the grading level of sublingual vessel among the three groups(P<0.05).The gastric cancer group had higher grades of sublingual vessel than chronic non-atrophic gastritis group and chronic atrophic gastritis group,the difference was statistically significant(P<0.05).There was no significant difference in sublingual vessel grading between chronic atrophic gastritis group and chronic non-atrophic gastritis group(P>0.05).The grade of sublingual vessel in early gastric cancer patients was better than that in advanced gastric cancer patients,and the difference was statistically significant(P<0.05).Conclusion The classification of sublingual vessel can be used as a reference index for clinical diagnosis of gastric cancer,suggesting that there is a relationship between sublingual vessel and the occurrence and development of gastric cancer.
