慢性萎缩性胃炎脾胃湿热证与热休克蛋白60、70及CD44s、CD44v6的相关研究

Study on Expression of HSP60, HSP70, CD44s and CD44v6 in Chronic Atrophic Gastritis Patients with Spleen-stomach Damp-heat Syndrome

为探讨慢性萎缩性胃炎(Chronic atrophic gastritis,CAG)脾胃湿热证与热休克蛋白60(HSP60)、热休克蛋白70(HSP70),细胞粘附分子标准型CD44蛋白(CD44s)及CD44的变异体(CD44v)之一CD44v6之间的关系,选择CAG患者71例进行胃镜检查,胃窦部活检标本行快速尿素酶试验及13C呼气试验,检测幽门螺旋杆菌(Hp),病理诊断和HSP60、HSP70、CD44s及CD44v6的免疫组织化学染色,分析比较它们的相关性。结果:①脾胃湿热组的萎缩和肠化程度高于脾虚组(P<0．05～0．01);②正常对照组胃粘膜内HSP60主要呈阴性或弱阳性表达,CAG脾胃湿热组及脾虚组患者胃粘膜内HSP60表达增强,且二者Hp的感染率均高于正常对照组(P<0．05～0．01),Hp的感染情况与HSP60的表达呈非常显著相关(P<0．01)。脾胃湿热组HSP60 表达与脾虚组相比无显著性差异,但脾胃湿热组HSP60表达有增强的趋势;③脾胃湿热组HSP70的表达与正常对照组、脾虚组相比无显著性差异(P>0．05),但脾胃湿热组强阳性表达率(71．0％)高于脾虚组(47．5％)(P <0．05);④脾胃湿热组CD44s和CD44v6的表达与正常对照组和脾虚组相比无显著性差异(P>0．05)。说明;①CAG脾胃湿热组胃粘膜的萎缩和肠化程度均重于脾虚组,可能是由于脾胃湿热证与炎症关系密切所致。②CAG脾胃湿热组及脾虚组HSP60的表达均较正常对照组增强,原因可能与Hp感染有关。③CAG脾胃湿热组HSP70的强阳性表达率强于脾虚组。④3组之间CD44s和CD44v6的表达无明显差异,说明CAG作为胃癌前疾病尚未出现CD44s和CD44v6的异常表达。

objective: To investigate the relationship between the heat shock protein 60 (HSP60), heat shock protein 70 (HSP70) , standard CD44 (CD44s) and CD44v6 in chronic atrophic gastritis (CAG) patients with spleen-stomach damp-heat syndrome. Methods: 71 CAG patients were selected, 31 cases coincided with spleen-stomach damp-heat (SSDH) group, 40 cases coincided with spleen-stomach qi-deficiency (SSQD) group, and 18 healthy persons as control group. Antral mucosal biopsies were obtained during endoscopy in these p...
