目的:探讨中西医结合治疗肝郁脾虚型腹泻型肠易激综合征患者的临床疗效及对炎性因子和肠黏膜屏障功能的影响。方法:选择温岭市中医院于2017年5月至2019年5月收治的腹泻型肠易激综合征患者86例，依据随机数字表法分为对照组和观察组，每组43例。对照组患者给予曲美布汀片治疗，观察组在对照组基础上结合自拟中药汤剂治疗。两组疗程均为6周。比较两组治疗疗效，治疗前后主要症状积分、炎性因子和肠黏膜屏障功能变化及不良反应。结果:观察组总有效率为93.02%(40/43)，高于对照组的67.44%(29/43)(χn 2＝8.871，n P<0.05)。观察组治疗后主要症状积分[(0.52±0.16)分、(0.46±0.12)分、(0.58±0.15)分、(0.39±0.09)分和(0.41±0.10)分]低于对照组[(1.28±0.25)分、(1.16±0.26)分、(1.34±0.27)分、(0.95±0.14)分和(0.93±0.17)分](n t＝16.790、16.030、16.135、22.064、17.289，均n P<0.05)。观察组治疗后血清白细胞介素6[(8.27±1.38)μg/L]和白细胞介素8[(2.63±0.43) μg/L]低于对照组[(14.39±2.37)μg/L和(4.37±0.56)μg/L](n t＝14.633、16.160，均n P<0.05)。观察组治疗后血浆内毒素[(2.68±0.46)U/mL]和D-乳酸[(4.87±0.79)μg/L]低于对照组[(3.97±0.63)U/mL和(7.39±0.95)μg/L](n t＝10.844、13.374，均n P<0.05)。两组均未发生严重不良反应。n 结论:中西医结合治疗腹泻型肠易激综合征患者临床疗效良好，可减轻炎性反应且可改善患者肠黏膜屏障功能，不良反应少。“,”Objective:To explore the therapeutic effect of Integration of Traditional Chinese and Western Medicine in the treatment of irritable bowel syndrome of diarrhea type of liver depression and spleen deficiency, and its influence on inflammatory factors and intestinal mucosal barrier function.Methods:From May 2017 to May 2019, 86 patients with diarrhea-predominant irritable bowel syndrome admitted to the Traditional Chinese Medicine Hospital of Wenling were randomly divided into observation group (43 cases) and control group (43 cases) according to random number table method.The patients in the control group were given trimetastatin tablets, while the patients in the observation group were given traditional Chinese medicine decoction on the basis of the control group.The two groups were treated for 6 weeks.The therapeutic effects, main symptom scores, inflammatory factors, intestinal mucosal barrier function and adverse reactions were compared between the two groups before and after treatment.Results:The total effective rate of the observation group was 93.02%(40/43), which was higher than 67.44%(29/43) of the control group(χn 2=8.871, n P<0.05). The main symptom scores of the observation group were (0.52±0.16)points, (0.46±0.12)points, (0.58±0.15)points, (0.39±0.09)points and (0.41±0.10)points, repectively, which were lower than those of the control group[(1.28±0.25)points, (1.16±0.26)points, (1.34±0.27)points, (0.95±0.14)points and (0.93±0.17)points](n t=16.790, 16.030, 16.135, 22.064, 17.289, all n P<0.05). The serum levels of IL-6[(8.27±1.38)μg/L] and IL-8[(2.63±0.43)μg/L] in the observation group were lower than those in the control group[(14.39±2.37)μg/L and (4.37±0.56)μg/L](n t=14.633, 16.160, all n P<0.05). The levels of plasma endotoxin[(2.68±0.46)U/mL] and D-lactate[(4.87±0.79)μg/L] in the observation group were lower than those in the control group[(3.97±0.63)U/mL and (7.39±0.95)μg/L](n t=10.844, 13.374, all n P<0.05). No serious adverse reactions occurred in both two groups.n Conclusion:The combination of traditional Chinese and western medicine has good clinical effect in treating diarrhea-predominant irritable bowel syndrome, which can alleviate inflammation and improve intestinal mucosal barrier function, with fewer adverse reactions.
