目的 探討功能性排便障礙人群心理評估中心理和情緒的變化。方法 采用SCL-90、SAS和SDS量表對72例功能性排便障礙患者進行心理評估并分析結果。結果 便秘組SCL-90測試的總分以及軀體化、抑郁、焦慮及精神病性這4項因子的評分結果均高于對照組（P＜0.001），2組其余各因子的評分結果差異沒有統計學意義（P＞0.05）。便秘組SAS和SDS測試的評分結果均高于對照組，表明便秘組焦慮和抑郁的評分均較對照組高（P＜0.001）。結論 功能性便秘患者不同程度伴隨有情緒和情感的異常，因此對該部分患者進行藥物干預的同時給予其心理輔導是非常有必要的。
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.
