Objective To investigate the protective effect of Jiawei Danshen Yin combined with microRNA-21 on IRI myocardial cells,and to study its protective mechanism. Methods H9C2 cardiomyocytes were cultured and divided into four groups: Blank group, IRI model group of cardiomyocytes,miR-21 group,miR-21 combined with Jiawei Danshen Yin group (JWDSY group). Apoptotic rate, apoptosis-related protein and PTEN signaling pathway expression of cardiomyocytes were detected. Results Electron microscopy showed that mitochondria in model group were damaged significantly , and ultrastructural damage in JWDSY group was alleviated; ELISA demonstrated that cTnl was elevated in model group and decreased in JWDSY group with statistical significance (P < 0. 01); flow cytometry re vealed that the apoptotic rate was significantly increased in model group (36. 79 ±2. 12) ,but markedly decreased in JWDSY group (14. 65 ± 0. 94), and the difference was statistically significant ( P < 0. 05 ). Western blot results showed that PTEN expression was uP-regulated and P-Akt expression down-regulated in model group,while PTEN expression decreased and P-Akt expression increased in JWDSY group, and the difference was statistically significant ( P < 0. 05 ). Conclusions miR-21 combined with Jiawei Danshen Yin can inhibit cardiomyocyte apoptosis and protect IRI cardiomyocytes by reducing PTEN expression and activating PI3K/Akt signaling pathway,.

OBJECTIVETo evaluate preliminarily the efficacy on functional constipation treated with electroacupuncture of different acupoint prescriptions.

METHODSOne hundred and four patients were randomized into a front-mu and back-shu points group (19 cases), a he-sea points group (34 cases), a he-sea, front-mu and back-shu points group (26 cases) and a western medication control group (25 cases). In the front-mu and back-shu points group, electroacupuncture was applied at bilateral Tianshu (ST 25) and Dachangshu (BL 25). In the he-sea points group, electroacupuncture was applied at bilateral Quchi (LI 11) and Shangjuxu (ST 37). In the he-sea, front-mu and back-shu points group, electroacupuncture was applied at unilateral Tianshu (ST 25), Dachangshu (BL 25), Quchi (LI 11) and Shangjuxu (ST 37). In the three groups above, the treatment was given 5 times a week in the first two weeks and 3 times a week in the next two weeks. In the western medication control group, mosapride citrate tablets were prescribed for oral administration, 1 table (5 mg) each time, 3 times a day, continuously for 4 weeks. The period of research was 9 weeks, including 1 week for baseline evaluation, 4 weeks for treatment and 4 weeks for follow-up. The weekly defecation frequency was taken as primary index, while the defecation difficulty and life quality score were taken as the secondary indices for the efficacy evaluation after treatment and in follow-up.

RESULTSAccording to the intention-to-treat (ITT) analytic principle, 104 cases were all enrolled in the final analysis. (1) After treatment, the weekly frequency of defecation was all increased significantly in the four groups (P < 0.05, P < 0.01). The efficacy of the three electroacupuncture groups was similar to that of western medication control group (P > 0.05). In follow-up, the increasing effect on the weekly frequency of defecation was maintained in the he-sea points group (P < 0.01), superior to the front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01); the weekly frequency of defecation was not improved in the rest three groups (P > 0.05). (2) After treatment, defecation difficulty was relieved in the he-sea points group, the he-sea, front-mu and back-shu points group and the western medication control group (P < 0.05, P < 0.01). In follow-up, the improvements were still significant in the he-sea points group and the he-sea, front-mu and back-shu points group (both P < 0.01). (3) After treatment, the life quality score was significantly improved in the patients of the he-sea points group (P < 0.05). The difference was not significant in the rest three groups as compared with that before treatment (all P > 0.05).

CONCLUSIONThe weekly frequency of defecation is increased effectively after treatment in the three electroacupuncture groups and the efficacy is similar to mosapride citrate tablets. The bilateral Quchi (LI 11) and Shangjuxu (ST 37) in he-sea acupoints increase significantly the weekly frequency of defecation, relieve defecation difficulty and improve life quality. Acupuncture efficacy is sustained for 4 weeks. This acupoints prescription is the best in the treatment of functional constipation.

Objective: To observe the effect of thermosensitive hydroxybutyl chitosan (HBC) hydrogel in the prevention of intrauterine adhesion in New Zealand white rabbits. Methods: Eighteen female New Zealand rabbits were randomly divided into 3 groups, i. e., normal control group, model group and HBC group. Normal control group underwent sham operation. The models of intrauterine adhesion were constructed by both mechanical damage and infection in model group and HBC group. In HBC group, 2 mL 1.5% thermosensitive HBC hydrogel was injected into the uterine cavity immediately after injury. Two rabbits were killed in each group 1 week, 2 weeks and 4 weeks after operation, respectively. The bilateral uterine tissues were collected. The endometrial morphology and quantity of glands were observed by hematoxylin-eosin staining. The area of fibrosis in endometrium was measured by Masson staining. Results: One week after operation, compared with normal control group, the columnar epithelial cells of endometrium gradually disappeared and the ratio of endometrial fibrosis area increased significantly in the other two groups. The number of glands also decreased. After 2 weeks, intrauterine adhesion was observed in model group, and the ratio of endometrial fibrosis area continued increasing, and the number of glands decreased further. However, in HBC group, there was no residual hydrogel in the uterine cavity, and the ratio of endometrial fibrosis area decreased and the number of glands increased. After 4 weeks, there was a recovery of columnar epithelium cells, the ratio of endometrial fibrosis area, and the number of glands in HBC group, which returned to the normal level. Conclusion: Thermosensitive HBC hydrogel can effectively prevent intrauterine adhesion in New Zealand white rabbits.

BACKGROUND: This meta-analysis of randomized controlled trials aimed to systematically evaluate the value of albuterol in the treatment of patients with acute respiratory distress syndrome (ARDS). DATA SOURCES: Randomized controlled trials on albuterol treatment of ARDS from its inception to October 2014 were searched systematically. The databases searched included: PubMed, Ovid EMBASE, Ovid Cochrane, CNKI, WANFANG and VIP. The trials were screened according to the pre-designed inclusion and exclusion criteria. We performed a systematic review and meta-analysis of the randomized controlled trials (RCTs) on albuterol treatment, attempting to improve outcomes, i.e. lowering the 28-day mortality and ventilator-free days. RESULTS: Three RCTs involving 646 patients met the inclusion criteria. There was no significant decrease in the 28-day mortality (risk difference=0.09;P=0.07,P for heterogeneity=0.22, I2=33％). The ventilator-free days and organ failure-free days were significantly lower in the patients who received albuterol (mean difference=-2.20;P<0.001,P for heterogeneity=0.49,I2=0％ and mean difference=-1.71,P<0.001,P for heterogeneity=0.60,I2=0％). CONCLUSIONS: Current evidences indicate that treatment with albuterol in the early course of ARDS was not effective in increasing the survival, but significantly decreasing the ventilator-free days and organ failure-free days. Owing to the limited number of included trails, strong recommendations cannot be made.
