[摘要] 目的 探讨降钙素基因相关肽与青壮年胆汁反流的关系。方法 对45例青壮年胆汁反流患者幽门区黏膜降钙素基因相关肽含量进行测定,与45例对照组进行比较,并测定胆汁反流组胃液胆汁酸浓度。结果 青壮年胆汁反流患者的幽门区黏膜降钙素基因相关肽含量较对照组降低(P<0.05),与胃液胆汁酸浓度无明显相关。结论 青壮年胆汁反流胃炎患者胃黏膜中降钙素基因相关肽含量降低,可能是胃黏膜适应性保护机制之一。

[Abstract] Objective To study the relationship of calcitonin gene-related peptide and bile reflux in the the young and middle-aged patients. Methods Pyloric mucosal calcitonin gene-related peptide concentration of 45 young and middle-aged patients with bile reflux and 45 control group were detected. Endogastric bile acid of the young and middle-aged patients with bile reflux were detected simultaneously. Results The level of pyloric mucosal calcitonin gene-related peptide concentration was decreased evidently in young and middle-aged patients with bile reflux. Compared with control group,the difference has statistics significance(P<0.05). There is no distinct correlatationship among calcitonin gene-related peptide and endogastric bile acid. Conclusion The decrease of gastric mucosal calcitonin gene-related peptide may be involved in the gastric mucosa adaptive protection of bile reflux in the young and middle-aged patients.

随着胃镜检查的普及,临床上青壮年胆汁反流的检出率比较高,但原因不明。本研究旨在通过对45例青壮年原发性胆汁反流患者幽门区黏膜降钙素基因相关肽(CGRP)含量及胃液胆汁酸浓度的测定,探讨降钙素基因相关肽在青壮年胆汁反流发病中的作用。
1 资料与方法
1.1 一般资料
选择非术后、幽门完整且不伴有消化性溃疡、胃十二指肠肿瘤及胆道疾病的青壮年,内镜检查明确为胆汁反流Ⅲ度(黄色液体从幽门口频繁涌出或(和)持续性喷射出或胃内布满黄绿色潴留液)的患者共45例,全部来自我院消化内镜中心2009年8月~2011年6月的门诊患者,其中男19例,女26例,年龄19~45岁,平均33.9岁(有5例患者胃镜检查前曾行24小时胃内胆汁监测确定存在碱反流)。同步选择45例内镜检查无明显异常的青壮年健康体检者为对照者,男21例,女24例,年龄20~45岁,平均31.2岁。排除消化系统器质性病变,如消化道肿瘤,肝、胆、胰、肠道病变等,排除肝胆胃肠手术史。检查前2周未使用胃肠动力药、制酸剂及胃黏膜保护剂等所有影响胃动力和胃肠分泌功能的药。
1.2 方法
对符合上述各项标准的胆汁反流组45例及对照组45例均作电子胃镜检查,由固定的内镜专业医生操作。胆汁反流组胃镜进入胃底即抽取胆汁约4~5mL,离心后取上清液测定胆汁酸浓度(用全自动罗氏生化仪检测,试剂盒购自北京九强生物技术公司)。两组均取幽门区黏膜组织块约10mg,漂洗、滤纸拭干、称质量,量取冷生理盐水1mL(保证组织块与生理盐水的重量体积比为10mg︰1mL),与组织块一起置入匀浆器进行匀浆,用冰冻离心机3000r/min 4℃离心15min,留取上清液测定CGRP含量(CGRP ELISA试剂盒购自上海沪峰生物科技有限公司,严格按试剂盒说明书进行操作)。
1.3 统计学方法
采用SPSS16.0统计软件,实验数据以均值±标准差(χ±s)表示,两样本均数间比较采用t检验 ......
