目的 探讨功能性排便障碍人群心理评估中心理和情绪的变化。方法 采用SCL-90、SAS和SDS量表对72例功能性排便障碍患者进行心理评估并分析结果。结果 便秘组SCL-90测试的总分以及躯体化、抑郁、焦虑及精神病性这4项因子的评分结果均高于对照组（P＜0.001），2组其余各因子的评分结果差异没有统计学意义（P＞0.05）。便秘组SAS和SDS测试的评分结果均高于对照组，表明便秘组焦虑和抑郁的评分均较对照组高（P＜0.001）。结论 功能性便秘患者不同程度伴随有情绪和情感的异常，因此对该部分患者进行药物干预的同时给予其心理辅导是非常有必要的。
Objective To investigate the effect and clinical significance of 3 d and 1 d bowel preparation method for colorectal carcinoma surgery on preoperative gut mucosal barrier function. Methods Plasma levels of D-lactate (D-LAC), diamine oxidase (DAO) and endotoxin (ET) were measured at 2 h before operation in 3 d bowel preparation group (50 cases) and 1 d bowel preparation group (50 cases), 25 cases of inguinal hernia were included as control group. D-LAC, DAO and ET were detected by using enzymatic spectrophotometric assay, spectrophotometric assay and limulus lysate test with azo chromogenic substrate, respectively. Results Preoperative plasma levels of D-LAC, DAO and ET in 3 d bowel preparation group were (10.25±1.43) mg/L, (5.82±0.80) U/ml and (10.11±1.41) ng/L respectively. In 1 d bowel preparation group the corresponding values were (10.19±1.35) mg/L, (5.80±0.81) U/ml and (9.82±1.35) ng/L respectively. There were no significant differences between 3 d and 1 d bowel preparation group (Pgt;0.05), compared with hernia group, 1 d and 3 d bowel preparation group were also no statistically significant differences (Pgt;0.05). Conclusions There are no significant preoperative gut mucosal barrier function damages in patients with 1 d and 3 d bowel preparation for colorectal carcinoma surgery, 1 d bowel preparation for colorectal carcinoma surgery can be performed in colorectal carcinoma patients, and 3 d bowel preparation can be used for certain special colorectal carcinoma patients.
