摘要: 摘要:目的  通过检测幽门螺杆菌(Helicobacter pylor,HP)相关上消化道疾病患者根除HP前后血清生长激素调素水平及胃粘膜生长激素调素表达水平变化,探讨根除HP对生长激素调素水平的影响及其临床意义。方法   在HP根除前后应用酶联免疫法测定血清生长激素调素的水平,应用RT-PCR方法检测胃粘膜生长激素调素表达水平,结果进行统计学分析。结果   HP感染的慢性浅表胃炎组、萎缩性胃炎组、消化性溃疡组及胃癌组其血清生长激素调素的水平分别为26.08±9.14μg/L、18.59±8.19μg/L、35.42±9.87μg/L和18.33±6.88μg/L。胃粘膜生长激素调素表达水平分别为0.86±0.26、0.75±0.22、1.38±0.29和0.21±0.09。根除HP治疗4周后浅表胃炎组患者血清及胃粘膜生长激素调素表达水平较治疗前升高,分别为29.35±8.83μg/L和1.10±0.32(P<0.01);消化性溃疡组血清及胃粘膜生长激素调素表达水平较治疗前下降分别为30.73±6.50μg/L和1.09±0.24(P<0.01),而萎缩性胃炎组根除治疗前后生长激素调素水平无明显变化(P>0.05)。浅表胃炎、萎缩胃炎及胃癌组血清PGI/PGII比值和血清ghrelin水平呈正相关,r=0.668(P<0.01)。结论    HP感染及根除HP治疗可以影响HP相关上消化道疾病患者的生长激素调素水平,生长激素调素水平的变化和胃蛋白酶原I/II相关。ghrelin可作为HP相关上消化道疾病及胃粘膜损伤程度的诊断和预后评估的检测指标之一。

Abstract: Objective  To discuss the impact and clinical significance of HP elimination on ghrelin, by detect the difference of serum ghrelin level and ghrelin express in gastric mucosa before and after HP elimination on upper gastrointestinal disease patients. Method    Determine serum ghrelin level before and after HP elimination with ELISA. Determine ghrelin express in gastric mucosa with RT-PCR. Analysis results with statistical method. Result   Serum ghrelin level in HP infected chronic superficial gastritis group, atrophic gastritis group, peptic ulcer group and gastric cancer group are 26.08±9.14μg/L, 18.59±8.19μg/L, 35.42±9.87μg/L and 18.33±6.88μg/L. Ghrelin express in gastric mucosa are 0.86±0.26, 0.75±0.22, 1.38±0.29 and 0.21±0.09. In chronic superficial gastritis group, both serum ghrelin level and ghrelin express in gastric mucosa were found risen to 29.35±8.83μg/L and 1.10±0.32(P<0.01) 4 weeks after HP elimination therapy. In peptic ulcer group, both serum ghrelin level and ghrelin express in gastric mucosa were found decreased to 30.73±6.50μg/L and 1.09±0.24(P<0.01). In atrophic gastritis group, significant ghrelin changes were not found before and after HP elimination. Serum PGI/PGII and serum ghrelin were found positively related in chronic superficial gastritis group, atrophic gastritis group and gastric cancer group, r=0.668(P<0.01). Conclusion  HP infection and HP eliminate rained influence on ghrelin level in patients with HP related upper gastrointestinal diseases. The changes of ghrelin level related on pepsinogen I/II. Ghrelin could be used as one of the indexes of gastric mucosa degree of diagnostic and prognostic evaluation.
