    Abstract

    AIM
To investigate the possible role of abnormal substance P (SP) and motilin (MTL) release in response to meals in the pathogenesis of chronic superficial gastritis with different types according to the traditional Chinese medicine.
, http://www.100md.com
    METHODS Chronic superficial gastritis (n=23) were divided into two groups: Gan-pi incoordination (group A, n=13) and Piyangxu (group B), and 10 healthy volunteers served as controls (group C). Blood was obtained from every subject for measurement of plasma levels of SP and MTL by RIA before and 30 and 120 minutes after meals.

    RESULTS Basal plasma SP levels were higher in group A than in groups C and B. Plasma SP levels were significantly elevated in group C at 30 minutes, and in group A at 120 minutes after meals, whereas release of SP in group B was affected slightly by meals. Plasma MTL levels were of great variation before meals. Increased releases of MTL in response to meals were seen in all the three groups, but none of them was of great significance. Basal MTL levels and MTL release after meal were slightly higher in group A than in the other two groups.

    CONCLUSION Higher basal SP levels before meals, delayed and prolonged SP release after meals, together with slightly higher plasma MTL concentrations, are associated with gastrointestinal motility disorders, and may play an important role in the pathogenesis of chronic gastritis with Gan-pi incoordination.

     目的 探讨餐前和餐后血浆P物质(SP)及胃动素(MTL)浓度在慢性胃炎中医证型间的变化规律.

    方法 慢性胃炎肝胃不和型13例,脾胃虚寒型10例,健康志愿者10名, 采用RIA法检测餐前、餐后30min和120min血 浆SP(pmol/L)和MTL(ng/L)浓度.
, 百拇医药
    结果 餐后血浆SP水平3组均增高.正常对照组餐后30min明显高于餐前(39.42±5.63 vs 34.83±5.45,P<0.05),餐后120min降至接近餐前水平(35.93±5.62).脾胃虚寒组餐后30min升高较餐前无统计学意义(38.56±6.26 vs 35.21±5.38,P>0.05),餐后120min也渐下降(37.12±6.07).肝胃不和组餐前SP水平(36.66±5.64)略高于其余2组,餐后30min升高幅度较小(39.22±6.14)而餐后120min继续升高(40.63±5.58,与餐前比P<0.05). 血浆MTL的结果表明,B、C 组餐前水平相近(分别为358.42±59.26和351.57±61.26),餐后有相似的变化(餐后30min分别为388.54±62.76和389.03±66.16;餐后120min分别为346.38±54.37和345.73±59.75),A组MTL的基础水平(378.33±71.49)和餐后水平(餐后30min为394.66±69.67,餐后120min为372.19±64.08)均较其余2组略高,但上述变化统计学上均无显著性意义(P均>0.05).
, 百拇医药
    结论 肝胃不和组餐前高SP水平和餐后迟发释放可能与胃肠运动障碍有关,并且可能是此型患者发病的病理生理学基础之一.脾胃虚寒组餐后SP的释放也有迟滞现象,提示此型患者可能也有运动功能障碍.餐前血浆MTL浓度变化较大,可能与消化间期周期性运动波动有关,肝胃不和组MTL的释放增加,可能与其运动失常有关,有待进一步研究.

    P物质(SP)与脾胃病关系的研究较少,而胃动素(MTL)与脾胃病的关系虽有不少研究,但仍无统一的看法[1].胃肠激素受多种因素的影响,为了排除其他因素的干扰,增加可比性,我们以慢性浅表性胃炎为研究对象,以病证相结合,研究血浆SP和MTL的变化规律,探讨它们与中医证型间的关系,以阐明慢性胃炎中医证型可能的病理生理学基础.

    1 对象和方法

    1.1 对象 根据中医临床的辨证与分型要点[2],对慢性胃炎肝胃不和型13例(A组,男8例,女5例,年龄20岁~66岁,平均35岁),脾胃虚寒型10例(B组,男7例,女3例,年龄20岁~60岁,平均36岁),健康志愿者10例(C组,男7例,女3例,年龄20岁~48岁,平均30岁),测定血浆SP和MTL水平.所有受检者均经内镜和病理诊断证实,同时调查病史和其它实验室检查,排除其他疾病,近期无服药史.

    1.2 方法 受检者禁食禁饮8h,于上午8:00空腹抽血10ml,然后进食1份标准餐,包括油煎鸡蛋1个(60g),黑芝麻糊40g,葱油饼干20g,温开水400ml,于餐后30和120min再各抽 取外周血10ml,注入预先备有10% EDTA(10μl)和抑肽酶(500μl)的试管中,在4℃下离心20min(3000r/min),取上清分装,-70℃保存.SP和MTL(分别购自北京华英放免技术所和东亚免疫技术所)的测定按说明书(RIA法)进行.结果以均数加减标准差表示,用方差分析进行统计.

    3 讨论本文结果表明,3组受检者餐后血浆SP水平均增高,但升高的幅度和时差有差异.正常对照组餐后30min SP水平明显高于餐前(P<0.05),餐后120min又降至接近餐前水平,脾胃虚寒组餐后30min血浆SP升高无统计学意义(P>0.05),餐后120min未完全恢复正餐前水平,而肝胃不和组餐前SP水平较其余2组略高,餐后30min升高的幅度较小,而在餐后120min继续升高(与餐前比P<0.05).3组MTL的变化相似,餐后30min均增高,餐后120min又降至餐前水平.在基础状态和进餐后,肝胃不和组血浆MTL水平均较其余2组高,但无统计学意义(P>0.05).SP广泛分布于全身各器官[3],在胃肠道,它主要存在于肠神经系统(包括粘膜下丛和肌间丛),是非肾上腺素能非胆碱能第3类神经-肽能神经的递质,少部分分布于肠粘膜上皮之间的EC1细胞.循环中的SP主要来源于小肠,进食对血浆SP水平的影响仍有争议,本文结果显示进餐对SP的释放有影响,但肝胃不和型患者餐后SP升高明显滞后,这可能与此型患者有明显胃潴留有关,提示SP释放的有效刺激可能来自小肠.SP强烈促进胃肠道的蠕动功能,其释放时相的改变可能导致继发性胃肠运动功能的失调.SP释放异常可能是慢性胃炎肝胃不和型发病的病理生理学基础之一.脾胃虚寒组餐后SP释放也有迟滞现象,而且受食物刺激影响的幅度较小,提示此型患者也可能有胃肠道运动的障碍. MTL主要由分布于小肠上部的Mo细胞分泌,受十二指肠内酸度的调节,并可能与胆汁分泌有关.MTL被称为消化间期激素,随着消化间期运动周期性波动而变化,所以空腹时血浆MTL浓度的变化较大[4].本文结果表明,空腹时3组受检者血浆MTL水平的差异无显著性意义,可能在较大程度上与此周期性运动波动有关.进食后,脾胃虚寒组MTL的变化与正常对照组相近,说明脾胃虚寒组MTL的释放正常.而肝胃不和组MTL水平无论餐前或餐后均较前2组略高,可能与其运动失常有关,有待进一步研究.
