摘　　要：为获得我国正常成人食管酸暴露的正常值范围，对５ｏ名健康成人进行２４小时ｐＨ监测。结果显示：５ｏ名正常成人中平均９８．６％的时间食管ｐＨ＞４，故以ｐＨ４作为酸反流的阈值。观察６项食管酸暴露的指标，得出９５％的正常值范围：ｐＨ＜４的总时间百分率为３．４％；ｐＨ＜４的立位总时间百分率为４，３％；ｐＨ＜４的卧位总时间百分率为４．３％；反流持续≥５分钟的次数≥２次；最长反流持续时间１６分钟；ｐＨ＜４的反流次数为６ｏ次；总计分１２．７分。门诊与住院检查结果比较，二者差异无显著性（ｐ＞０．０５）。本结果与国外资料不同，可能与种族、地区差异、人群生活习惯、饮食结构的不同或ＬＥＳ功能等有关。To obtain the normal values of esophageal acid exposure in healthychinese adults,We monitored with 24 esophageal pH in 50 normal adults,which,revealed that in all subjects the esophageal pH remained above 4 for 98.6 % of thecircadian,hence pH 4 was defined as the threshold of acid reflux. Obeservation of 6components of esophageal acid exposure suggested the following normal values for95 % of all subjects:Total fraction time pH<4 3.4%;upright fraction time pH<44.3%;supine fraction time pH<4 4.3%;number of reflux episodes≥5.0 minutes≤ 2;1ongest reflux episode 16min; number of reflux episodes 60;composite score l2.7.Nosignificant difference was noted between the results from inpatients and thoseoutpatients.(p>0.05)Our conclusion differed slightly from that of the reports abroad.Apart form the regional and racial factors,the differences of living habits,dietcomposition and the LES function can all be responsible for it.
