Expressions of HSP 70 and NF-kappaB in the peripheral blood lymphocyte of chronic gastritis patients of different syndrome patterns].

To study the expressions of heat shock protein70 (HSP 70) and nuclear factor-kappa B (NF-kappaB) in the peripheral blood lymphocyte of chronic gastritis (CG) patients of Pi-Wei hygropyrexia syndrome (PWHS) and Pi-qi deficiency syndrome (PQDS), and to explore their correlation with Helicobacter pylori (Hp) infection. Recruited were totally 86 CG patients who visited at the clinics of gastroenterology, First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine, including 67 patients of PWHS (30 of predominant-dampness, 30 of equal dampness and heat, and 30 of predominant-heat) and 19 patients of PQDS. Another 12 volunteers from healthy employees and students of Guangzhou University of Traditional Chinese Medicine were recruited as the control group. Their peripheral blood was collected. The Hp infection was detected using ASSURE Hp rapid test. The expressions of HSP 70 and NF-kappaB in the peripheral blood lymphocyte were detected using flow cytometry. The Hp infection rate was 37. 31% in the GS patients of PWHS and 36. 84% in the GS patients of PQDS (P>0.05). Compared with the control group, the expression of HSP 70 decreased in the PWHS predominant-heat group, and the expression of NF-kappaB increased in the PWHS predominant-heat group and the PQDS group (P<0.05). The expression of NF-kappaB were higher in the positive Hp infection patients of PWHS and PQDS than in the control group (P<0.05). The expression of HSP 70 was higher in the positive Hp infection patients of PQDS than in the negative Hp infection patients of PQDS (P<0.05). Besides, the coefficient correlation was -0. 023 between HSP 70 and Hp infection, and 0. 027 between NF-KB and Hp infection (P>0.05). The increased expression of NF-KB in the peripheral blood lymphocyte of CG patients of PWHS and PQDS might reflect the pathogenic roles of "inner evil" in Chinese medicine theories. The increased expression of HSP 70 in CG patients of PQDS and decreased expression of HSP 70 in CG patients of PWHS might reflect "vital qi fighting against evils" and "exuberance evils and feeble vital qi" in the body. Hp infection might not be the only factor resulting in the occurrence of PWHS or PQDS.
