[摘要] 目的 該項研究旨在通過測定消化性潰瘍、慢性胃炎患者及正常對照組血清/血漿中Ghrelin和生長抑素(SST)在未接受抑酸藥物治療前的含量,探討Ghrelin和SST在消化性潰瘍患者循環血液中的表達情況以及兩者之間的相關性。方法 用酶聯免疫方法及放射免疫方法分別檢測26例GU患者、26例DU患者、22例慢性胃炎患者、15例正常對照血清/血漿中Ghrelin和SST的水平。結果 ①血清中Ghrelin的水平DU、GU組顯著高于對照組(P<0.01~0.05),且DU組還高于慢性胃炎組(P=0.007),其他各組間無明顯統計學意義。②血漿中SST水平GU、DU、慢性胃炎組高于對照組(P<0.01~0.05),且GU高于DU組(P=0.01)。③Ghrelin與SST之間的相關系數為GU:r=0.445(P=0.023),DU:r=0.462(P = 0.017),正常對照組:r=0.725(P=0.002)。結論 消化性潰瘍患者血清中Ghrelin及SST的水平是顯著增高的,可能與潰瘍的發病存在一定的關系。Ghrelin及SST在消化性潰瘍、正常對照組中具有相關性。

[Abstract] Objective To study serum Ghrelin and plasma somatostatin before the treatment with acid suppression medication and to study their synthesis and secretion in peptic ulcer as well as the correlation between the two. Methods To dectet the serum Ghrelin and plasma somatostatin levels in 26 cases of gastric ulcer,26 cases of duodenum ulcer,22 cases of chronic gastritis,15 cases of healthy volunteer blood donation by ELISA method and radio immunoassay method. Results ①The serum Ghrelin level was gastric ulcer(GU):(3.80±1.38)ng/mL,duodenum ulcer(DU): (4.14±1.05)ng/mL,chronic gastritis(CG):(3.28±1.00)ng/mL,healthy volunteer(N):(2.98±0.70)ng/mL. DU and GU is significantly higher than the N level(P<0.01~0.05);DU is higher than the CG(P = 0.007). ②The plasma somatostatin level was GU:(48.19±16.07)pg/mL,DU:(37.54±17.34)pg/mL,CG:(42.04±17.36)pg/mL,N:(26.74±8.25) pg/mL. GU,DU,CG are significantly higher than the Nlevel(P<0.01~0.05);GU is significantly higher than the DU(P = 0.01). ③The correlation coefficient between Ghrelin and somatostatin.GU:r=0.445(P = 0.023),DU:r=0.462(P = 0.017),CG:r=-0.061(P = 0.788) N:r=0.725(P=0.002). Conclusion The serum Ghrelin and plasma somatostatin levels in peptic ulcer are significantly higher,which is related to peptic ulcer development,and there is some correlation between the two in PU and N.

消化性潰瘍主要指胃潰瘍和十二指腸潰瘍,因潰瘍形成與胃酸/胃蛋白酶的消化作用有關而得名。此外,NSAID和HP,吸煙,遺傳,胃十二指腸運動異常,急性應激都與消化性潰瘍發病有不同程度關系。近來研究表明:人生長激素釋放多肽(Ghrelin)有促胃酸分泌及胃腸運動作用,生長抑素能引起胃腸道分泌變化,二者對消化性潰瘍的發病是一個值得探討的課題。本研究采用酶聯免疫吸附法(ELISA)及放射免疫方法(RIA)測定消化性潰瘍患者
血清/血漿中Ghrelin和SST的含量,以探討它們在消化性潰瘍發病中的作用及兩者之間的相互關系。
