Objective To investigate the effects of adiponectin on angiotensin Ⅱ-induced extracellular matrix production of mesangial cells(MCs) and its possible signaling pathway.Methods RT-PCR and indirect immunofluorescence examination were performed to detect the adiponectin receptors in MCs.Quantitative real-time PCR and enzyme-linked immunosorbent assay (ELISA) were used to observe the effects of adiponectin on angiotensin Ⅱ-induced transforming growth factor β1(TGF-β1) and fibronectin production of MCs.Western blotting was used to measure the ratio of p-AMPK to total AMPK.Results(1)Adiponectin receptors 1 and 2 were found in MCs. (2)The up-regulated mRNA and protein expression of TGF-β1 and fibronectin in MCs induced with 10-7 mol/L angiotensin Ⅱ (Ang Ⅱ) was significantly inhibited by 10 mg/L adiponectin (P＜0.05).(3)The p-AMPK/AMPK ratio was significantly increased after incubation with adiponectin for 15 min and 30 min(vs 0 min, P＜0.05), which suggested that adiponectin could activate the AMPK signaling pathway in MCs.The activation of AMPK signaling pathway was blocked by 40 μmol/L compound C, a specific inhibitor of AMPK. (4)The inhibitory effects of adiponectinonangiotensin Ⅱ-upregulatedTGF-β1andfibronectinexpressioninMCswere significantly relieved by 40 μmol/L compound C (P＜0.05).Conclusions There are adiponectin receptors 1 and 2 in MCs.Adiponectin has inhibitory effects on the angiotensin Ⅱ-upregulated TGF-β1and fibronectin expression in MCs.AMPK signaling pathway may play an important role in the effects of adiponectin above-mentioned.

Objective To summarize the experience of tension-free repair for inguinal hernia in the preperitoneal space using modified surgical mesh. Methods From Dec 2008 to May 2010, 134 cases with 138 reducible primary inguinal hernia were randomly divided into two groups. Sixty-seven patients (70 hernias) in the study group underwent tension-free repair in the preperitoneal space by modified surgical mesh, while the control group (67 cases, 68 hernias) underwent Rutkow's herniorrhaphy by surgical mesh.Results Postoperatively 127 cases (95%) were followed up from 2 to 18 months with an average of 9. 2months[64 cases of the test group were followed up with an average of(9 ±4) months, 63 cases of the control group followed up with an average of (9 ± 5 ) months]. There was no recurrence. No significant differences were found between the two groups in the operation time (P = 0. 697), blood loss (P = 0. 318 ),hospital stay (P = 0. 116) and total postoperative complications (P = 0. 080). The visual analogue scale of the study group was lower than the scale of the control group ( P = 0. 048 ). Conclusions Modified surgical mesh is more comfortable in the treatment of inguinal hernia with tension-free repair in the preperitoneal space with a comparative result to Rutkow's herniorrhaphy by surgical mesh.

OBJECTIVETo compare the differences in the clinical efficacy on insomnia between shujing massage therapy and medication with estazolam.

METHODSEighty patients of insomnia were randomized into a shujing mass age therapy group (40 cases) and a medication group (40 cases). In the shujing massage therapy group, the spreading massage manipulation was applied along the running course of the gallbladder meridian of foot-shaoyang on the temporal area. The pressing and kneading manipulation was done at Yangbai (GB 14), Benshen (GB 13), Toulinqi (GB 15), Zhengying (GB 17), Chengling (GB 18), Shuaigu (GB 8), and Fengchi (GB 20), etc, 1 min at each acupoint. In the medication group, 1 mg estazolam was taken orally half an hour before sleep. The treatment was given once every day in the two groups. After the continuous treatment for 1 month, every dimensional score and the total score in the Pittsburgh sleep quality index scale (PSQI) and the clinical efficacy were evaluated between the two groups.

RESULTSAfter the intervention, the each item score of PSQI was improved as compared with that before treatment in the patients of the two groups (all P<0. 05). The differences in sleep time and the time for falling into sleep were not significant between the two groups (both P>0. 05). In the shujing massage therapy group, the scores of sleep quality, sleep efficiency, sleep disturbance and daytime dysfunction, as well as the total score were all lower than those in the medication group (all P<0. 05). The total effective rate was 92. 1% (35/38) in the shujing massage group and was 84. 2% (32/38) in the medication group, indicating the significant difference (P<0. 05).

CONCLUSIONShujing massage therapy achieves the superior efficacy on insomnia compared with the oral administration of estazolam.
