Objective To investigate the role of mucins secretion in the process that bifid triple viable capsule attenuates the recurrence of murine experimental colitis. Methods Mice were randomly allocated into BIFICO group (gavage with bifid triple viable capsule), 2,4,6-trinitrobenzenesulfonic acid (TNBS) group (gavage with phosphate-buffered saline), and normal control group. Intrarectal TNBS/ethanol challenge was given to mice on Day 0 followed by rechallenge on Day 5 ( 125 mg/kg and 180 mg/kg, respectively). On Day 5 several mice in both groups were randomly sacrificed before the second TNBS challenge and the remaining mice were sacrificed on Day 7. Disease activity index (DAI) was measured throughout the experiment. Inflammatory score was evaluated and MUC2 expression was determined using immunohistochemistry method. Results Recurrence of colitis was successfully simulated by challenging mice with two times of TNBS/ethanol solution. Compared with the TNBS group, DAI ( 1.39 ± 0. 68 vs. 2.39 ± 0.73, P = 0.003) and inflammatory score (2. 11 ± 0.78 vs. 3.22 ± 0. 97,P =0.03) were significantly decreased in BIFICO group after the second TNBS challenge. BIFICO administration significantly increased MUC2 expression (8. 67 ± 0. 87 vs. 7.86 ± 1.10, P = 0. 042 ) in BIFICO group compared with TNBS group before the second TNBS challenge. Conclusion Bifid triple viable capsule may enhance mucosal barriers by promoting mucins secretion, and thus attenuates the recurrence of murine colitis.

Objective:To evaluate the clinical efficacy and safety of oral mifepristone (10 mg/day) versus placebo in the preoperative treatment of uterine fibroids.Methods:This study was a multi-center, randomized, double-blind, placebo, parallel controlled trial. A total of 132 patients with uterine fibroids were randomly divided into study group and control group, with 66 cases in each group. The patients in the study group orally took 1 tablet/day of mifepristone (dose of 10 mg/tablet), the patients in the control group orally took 1 tablet/day of placebo, and both groups were treated for 3 months. The primary efficacy evaluation indicators were the change rate of maximum fibroid volume; the secondary efficacy evaluation indicators included amenorrhea rate, improvement of subjective symptoms and anemia; the safety evaluation indicators included the analysis of adverse events and changes in laboratory biochemical indicators.Results:At the end of treatment, the maximum leiomyoma volume was reduced by 25.97% (95% CI: -34.79%--15.95%) in the study group and reduced by 1.51% (95% CI: -13.03%-11.54%) in the control group. The change rate of the maximum leiomyoma volume before and after treatment in the study group was significantly greater than that in the control group, and the difference in the change rate of the maximum leiomyoma volume between the two groups was -24.84% (95% CI: -36.56%--10.94%), which was much higher than the 10% superiority threshold goal set by this study within the 95% CI interval. At the end of treatment, the complete amenorrhea rate [84% (52/62)], dysmenorrhea elimination rate [98% (61/62)], and menstrual blood loss disappearance rate [87% (54/62)] in the study group were significantly higher than those in the control group (all P<0.05). At the end of treatment, the mean hemoglobin [(131±13) g/L], red blood cell count [(4.5±0.4)×10 12/L] and hematocrit (0.39±0.03) in the study group were significantly increased compared with the baseline, and the differences had statistical significance (all P<0.05); after treatment, the differences in the above three indicators between the two groups had statistical significance (all P<0.01). The serum estradiol level in the study group was significantly lower than that in the control group at the end of treatment, and the difference was statistically significant ( P<0.01). There were no significant differences in follicle-stimulating hormone and cortisol levels before and after treatment between the two groups ( P>0.05). The overall incidences of any adverse event were not significantly different between the two groups (all P>0.05). Abdominal pain was the most common adverse event in the study group [9% (6/65)], but the incidence was not significantly increased compared with the control group [3% (2/64); P>0.05]. Conclusion:Compared with placebo, oral mifepristone 10 mg/day is significantly superior to placebo in reducing the size of uterine fibroids and improving anemia, without significant adverse reactions, and could be used as a drug treatment for patients with of uterine fibroids before surgery.

Objective To systematically review the efficacy and safety of repetitive transcranial magnetic stimulation (rTMS)for post-stroke dysphagia. Methods The clinical trials about rTMS for post-stroke dysphagia were searched on Pubmed,EMbase,MEDLINE,Cochrane library,China National Knowledge Infrastructure (CNKI),Chinese BioMedical Literature Database on disc (CBMdisc),and Wanfang database with computers. Two independent reviewers selected the literatures by the inclusion and exclusion criteria,data extraction and cross-checking,and then conducted the analysis. Results A total of seven trails (228 patients,136 of them in a rTMS group and 92 in a control group)were included. Four randomized controlled trials (RCTs)were used for Meta-analysis (54 patients in the rTMS group,42 in the control group). The other three non-RCTs were only reviewed systematically. (1)Meta-analysis showed that the improvement of swallowing function score after rTMS was better than that of the control group (SMD=1. 73,95%CI 0. 45 to 3. 01;P=0. 008). (2)After high-frequency rTMS (>1 Hz),there was significant difference in the improvement of swallowing function score between the two groups (SMD=1. 60,95%CI 0. 10 to 3. 11;P=0. 04). Compared to the control group,there were also significant differences in the improvement of some swallowing function scores in low-frequency rTMS (1 Hz),suggesting the potential advantages of low-frequency therapy. (3)After rTMS,there was no significant difference in the improvement of Barthel index in patients with stroke compared with the control group (MD= -21. 60,95%CI-36. 21 to-7. 00;P=0. 004). (4)In terms of adverse reactions,seven trials did not report any adverse events, such as headache,tinnitus or epilepsy,etc. Conclusion Using rTMS may significantly promote the recovery of swallowing function for patients with post-stroke dysphagia,and it is both safe and effective.
