目的观察复方植物纤维粉改善人体功能性便秘的效果。方法将兰州大学第二医院西固医院体检中心参加体检的309例功能性便秘患者随机分为观察组和对照组,观察组156例,冲服复方植物纤维粉;对照组153例,服用安慰剂。7 d后观察各组的排便次数、排便状况、粪便性状及粪便含水率变化;记录不良反应,评估效果。两组均数比较采用成组t检验,自身对照采用配对t检验,效果评定采用χ2检验。结果试食7 d后,观察组试食后排便次数、排便状况、粪便性状及粪便含水量分别为(0.69±0.16)次、(1.15±0.32)分、(1.08±0.58)分,(74.91±8.70)%。与试食前(0.30±0.16)次、(1.58±0.29)分、(1.34±0.28)分,(62.66±10.08)%相比,排便次数增加,排便状况和粪便性状积分下降,粪便含水率增加(P<0.05);与对照组比较,以上四项指标均有改善(P<0.05);两组有效率分别为72.44%、22.22%,观察组显著高于对照组。结论复方植物纤维粉有改善人体功能性便秘的效果。
Objective To observe the effect of compound plant fiber powder on improving functional constipation in the human body. Methods A total of 309 patients with functional constipation who participated in the physical examination in the Physical Examination Center of the Second Hospital of Lanzhou University, were randomly divided into the observation group and the control group. 156 cases in the observation group were treated with compound plant fiber powder. The control group received placebo. After 7 days, the number of defecation, defecation, stool characteristics and stool water content in each group were observed. Adverse reactions were recorded and the effects were evaluated. The two groups were compared using group t test, self-control using paired t test, the effect of evaluation using χ2 test. Results After 7 days, the defecation frequency, defecation status, stool performance and stool water content in the observation group after diet for 7 days were (0.69 ± 0.16), (1.15 ± 0.32), (1.08 ± 0.58), (74.91 ± 8.70)%. Compared with the pre-test (0.30 ± 0.16), (1.58 ± 0.29), (1.34 ± 0.28), (62.66 ± 10.08)%, the defecation times increased, the defecation status and stool traits decreased, and the stool moisture content increased P <0.05). Compared with the control group, the above four indexes all improved (P <0.05). The effective rates of the two groups were 72.44% and 22.22% respectively. The observation group was significantly higher than the control group. Conclusion Compound plant fiber powder has the effect of improving functional constipation in the human body.
