【摘要】目的:本研究旨在探讨胃癌前病变(Precancerous lesions ofgastric cancer, PLGC)患者血清胃癌单克隆抗体7 相关抗原(monoclonal gastric cancer 7 antigen, MG7-Ag)水平与中医证型的关系。方法:对南京中医药大学镇江附属医院收治的 PLGC 患者进行前瞻性横断面研究。并用 ELISA 法测定血清 MG7-Ag 水平。结果:共收治 PLGC 患者200例,其中男性91例,女性109例。脾胃湿热证、胃阴不足证、肝胃郁热证、肝胃气滞证、脾胃虚弱证及胃络血瘀证患者 MG7-Ag 水平分别为(3.44±1.82) U/ mL、(4.32±1.92)U/mL、(3.81±1.67) U/mL、(3.65±1.70)U/mL、(4.02±2.07)U/mL、(5.60±1.93)U/mL,组间比较差异有统计学意义(P <0.05)。结论:胃阴不足证与胃络瘀血证 PLGC 患者血清 MG7-Ag 水平最高,可作为筛选高危人群进行内镜精查的参考,提高早期胃癌的检出率。

【Abstract】Objective:The purpose of this study was to explore the relationship between serum monoclonal gastric cancer 7 antigen(MG7-Ag) level and TCM Syndrome Types in patients with Precancerous lesions of gastric cancer(PLGC).Methods:A prospective cross-sectional study was conducted on PLGC patients treated in Zhenjiang Affiliated Hospital of Nanjing University of traditional Chinese medicine. Serum MG7 Ag level was measured by ELISA.Results:A total of 200 patients with PLGC were treated,including 91 males and 109 females. The levels ofMG7 Ag were(3.44±1.82)U/mL,(4.32±1.92)U/mL,(3.81±1.67)U/mL,(3.65±1.70)U/mL,(4.02±2.07)U/mL and(5.60±1.93)U/mL in patients with spleen stomach damp heat syndrome,stomach yin deficiency syndrome,liver stomach stagnation syndrome,spleen stomach qi stagnation syndrome and stomach collateral blood stasis syndrome,respectively,The difference was statistically signi?cant(P<0.05).Conclusion:The level of serum MG7 Ag in PLGC pa- tients with gastric Yin deficiency syndrome and gastric collateral blood stasis syndrome is the highest,which can be used as a refer- ence for screening high-risk groups for endoscopic examination and improving the detection rate of early gastric cancer.

胃癌前病变(Precancerous lesions ofgastric cancer,PLGC)是胃癌发生发展的一个重要阶段。 PLGC 包括肠化生(IM)、肠异型增生(DYS)和上皮内瘤变(IN),通常发生在萎缩性胃炎(AG)的基础上。 AG、IM 和 DYS 的终生癌症风险分别为1/50、1/39和 1/19[1-2]。早期发现和治疗 PLGC对降低胃癌的发病率具有重要意义。 Jiang 等[3]发现血清胃癌单克隆抗体7相关抗原(monoclonal gastric cancer 7 antigen,MG7-Ag)是胃粘膜恶性转化的潜在阳性标志物。 Guo等[4]研究表明,血清 MG7-Ag 在胃粘膜由良性病變向癌前病变发展过程中表达水平逐渐升高。因此, MG7-Ag 可作为 PLGC 向胃癌发展的早期预警指标[5]。中医的证即证候,是指疾病发展过程中某一个阶段的病理属性的概括。在慢性胃炎和胃癌的诊断中,中医证候是公认的[6]。然而, PLGC、MG7- Ag 水平与中医证型的关系尚不清楚。因此,本研究分析血清MG7-Ag 水平与中医证型的关系,以评估不同中医证型的癌症风险。……
