正常传输型慢性便秘患者不同病程构成比的分析

Analysis on the Component Ratio of Chronic Constipated Patients with normal transit at Different Disease Courses

为探讨正常传输型慢性便秘患者的病程与患病构成比之间的关系，本研究将48例正常传输型慢性便秘患者的病程按照≤10年（A期）、11～20年（B期）、〉20年（C期）分为3个阶段，其中A期按每2年为一个亚期划分为5个亚期，分析不同病程患病构成比之间的差异。结果显示，正常传输型慢性便秘患者A、B、C期患病的构成比分别为79．17％、8．33％和12．50％，A期与B期、C期病程构成比相比，差异均有统计学意义，χ_AB^2=66．0629，χ_AC^2=45．1927，P〈0．01。A期病程与B期和C期病程之和的构成比之间差异亦有统计学意义，χ^2=15．2915，P＜0．01。A期病程中各亚期之间患病构成比差异无统计学意义，P〉0．05。结果表明，正常传输型慢性便秘患者可能存在伴随病程延长患病减少的趋势。

This study was to explore the relationship between the disease course and component ratio of chronic constipated patients with normal transit. In this study 48 patients were divided into three classes according to their disease courses, i. e≤10years, stage A; 10-20years, stage B; 〉20years, stage C. Then, stage A was again divided into 5 substages by 2 years, so as to analyze the differences between different disease courses and component ratio. As results,the component ratio of A：B.C stage was 79.17% ：8.33%： 12.50G ;the component ratio differences between stage A and B,as well between stage A and C all had statistical significance（χ_AB^2=66. 0629, χ_AC^2 =45. 1927, P 〈0.01）, correspondingly, the disease course difference between the disease couse of stage A and the sum of stage B disease course plus stage C disease course also had statistical differences（χ^2 =15. 2915, P 〈0.01）;but among the substages of stage A their component ratio differences had no statistical differences（ P〉0.05）. Results show that in chronic constipated patients with normal transit incidence decrease trend could appear along with disease courses prolonging.
