摘要
目的探讨胃瘦素在幽门螺杆菌(Hp)相关性胃炎中的病理生理学作用。方法根据胃镜和组织学检查诊断为慢性胃炎的61例患者作为研究对象。用Hp-ureA-PCR、14C呼气试验、快速尿速酶试验对受检对象做Hp感染诊断用酶联免疫吸附试验检测Hp感染阳性和阴性患者胃黏膜组织上清液、血清瘦素的水平,用放射免疫实验检测胃黏膜组织上清液IL-1β、IL-1Ra的水平。结果其中Hp感染阳性的慢性胃炎患者31例,Hp感染阴性的慢性胃炎患者30例。Hp感染阳性组胃瘦素水平明显高于Hp感染阴性组,两组间比较差异有统计学意义(P<0.01),血清瘦素水平两组间比较差异无统计学意义(P>0.05);胃组织上清液IL-1β水平两组间比较差异无统计学意义(P>0.05)。相关性分析显示Hp感染阳性组胃瘦素与IL1β显著负相关(r=-0.78,P<0.01)。结论胃瘦素可能通过自分泌或旁分泌作用局部影响胃的功能,同时可能通过调节IL-1β/IL-1Ra的平衡而在Hp相关性胃炎的发生发展及转归中起作用。
Objective To explore the pathophysiological role of gastric leptin in helicobacter associated gastritis.Methods Patients undergoing gastroscopy were involved in the study.Helicobacter pylori infection was diagnosed by use of Hp-ureA-PCR,^(14)C urea breath test and rapid urease-nessler′s test. The level of leptin in local gastric mucosa and plasma were detected by ELISA. The level of IL-1β and IL-1ra in local gastric mucosa were detected by RIA.Results Total of 31 H pylori positive and 30 H pylori negative patients with chronic gastritis were founded. The level of Leptin and IL-1ra in the gastric mucosa in H pylori positive patients were significantly increased as compared with that in H pylori negative group (P< 0.01). The level of plasma leptin and IL-1β were no statistically different between two groups(P> 0.05).Gastric leptin closely related to IL-1β in H pylori positive group(r= -0.78,P< 0.01), but not to that in H pylori negative group .Conclusions Gastric leptin may influence the gastric function by pacrcrine and autocrine roles; Gastric leptin may play a role in the development of helicobacter pylori associated gastritis by modulation the balance of IL-1β/IL-1ra.
