The patients in the EA group were treated with EA at zúsānlǐ（足三里ST36）. Gān shù（肝俞BL18）, Pǐshù（脾俞BL20）. Tàichōng（太冲LR36） and Qízhōngsìbiān（脐中四边）once daily for 4 weeks, while the patients in the Qibei mixture group were treated with 50 mL of Qibei mixture twice daily, the combination group with the above-mentioned EA and Qibei mixture, and the medication group with 1 tablet compound diphenoxylate twice, 3 g montmorillonite powder three times and 25 mg amitriptyline twice daily. The defecation frequencies, stool properties, accompanying symptom score, life quality score and adverse reactions were recorded pre-treatment,at the end of treatment and 6 weeks post-treatment for the four groups.Results： Compared with pre-treatment, the defecation frequencies, stool property score and accompanying symptom score were all decreased significantly at the end of treatment in each group（all P〈0.01）,while the scores of nine dimensions of quality of life were all increased significantly（all P〈0.01）. The above-mentioned indices were better in the combination group than in the other groups（all P〈0.05）.Compared with the end of treatment, no significant recurrences of the above-mentioned indices had occurred in the combination group or the EA group at 6 weeks post-treatment（both P〉0.05）, but these indices all recurred significantly in the group given Qibei mixture and the medication group（P〈0.05）.The short-and long-term total effective rates in the combination group both showed significant differences from those in the other groups（P〈0.05, P〈0.01）. No serious adverse reactions occurred in the four groups.Conclusion： EA and Qibei mixture can decrease defecation frequencies, improve stool properties, and alleviate accompanying symptoms to increase life quality, but the therapeutic effect of combination therapy is greater, with better reliability and long-term efficacy.展开更多

This study aimed to evaluate the effect of PhenActiv<sup>TM</sup>, a novel green kiwifruit extract, on gastrointestinal tract (GIT) function in otherwise healthy adults. Methods: 41 healthy adults with mild GI discomfort were enrolled in this double-blind, randomized, placebo-controlled study. Participants were randomized to either take 3.0 g/day of PhenActiv<sup>TM</sup> or a placebo for 6 weeks. Interviews were conducted at baseline, week 3 and week 6, with participants completing questionnaires regarding GI symptoms. Frequency of bowel movements was self-recorded daily. Results: There were no differences in daily and weekly defecation frequency and stool characteristics in either group. The active and placebo groups significantly improve GSRS scores (p , only the active group had a significant improvement in the IBSSS and PAC-QOL scores (p < 0.05) from baseline. Neither group had changes in sleep quality, quality of life and fatigue, plasma zonulin concentrations or macular pigment optical density scores. The product was well tolerated with no GI disturbances or adverse events being reported. Conclusion: Supplementation of 3.0 g/day of PhenActiv<sup>TM</sup> for 6 weeks did not improve defecation frequency or stool composition in healthy adults, but did improve perceived symptoms of GIT function, including symptoms of functional GIT disorders, IBS and constipation. The product was well tolerated and future trials investigating higher doses with more participants and/or a different population would be beneficial.展开更多
