Objective To observe the effect of sinomenine(SINO) on immune function of adjuvant arthritis(AA) rats.Methods SD rats were randomized into normal group,model group,SINO groups(treated with gastric gavage of SINO at the doses of 60,120 and 240 mg/kg respectively),and glucosides of Tripterygium Wilfordii(30 mg/kg) group.Except the normal group,the rats in other groups received subcutaneous injection of the complete Freund's adjuvant 0.1mL into the left hind foot to induce AA.The medication began from 12 days after the modeling and lasted 12 days.The pedal swelling and joint function scores were observed in different time.Radioimmunoassay was used to detect the contents of interleukin-1?(IL-1?) and tumor necrosis factor ?(TNF-?) in synovial cells.Expression of IL-1? and TNF-? mRNA was examined by reverse transcription-polymerase chain reaction(RT-PCR) assay.Results SINO at different concentrations decreased the pedal swelling and arthritis scores to various degrees,inhibited the production of IL-1? and TNF-? in the synovial cells,reduced the expression of IL-1? and TNF-? mRNA,and recovered the normal histological features of synovial cells in AA rats.Conclusion The therapeutic mechanism of SINO for rheumatoid arthritis may be related with the inhibition of secretion of inflammatory mediators in synovial cells,and with the recovery of histological features of synovial cells.

OBJECTIVETo assess the clinical effectiveness of volar and radial column approach by plate fixation for the treat- ment of unstable fracture of distal radius.

METHODSAccording to Cochrane Systematic Review, Medline, Embase, Cochrane Li- brary, CNKI and CBM, randomised controlled trials (RCTs) of volar and radial column approach by plate fixation for the treat- ment of unstable fracture of distal radius were searched for from 1966 to 2014. Data analysis was performed with the Cochrane Collaboration's RevMan 5.0 software.

RESULTSTotally 391 patients of 6 RCTs and 2 retrospective cohort studys were included and divided into volar plate group (187 cases) and radial column plate group (204 cases). Meta-analysis result showed: compared with radial column plate group, volar plate group had significant difference in recovery of wrist function [SMD = 0.74, 95% CI (0.47, 1.01), P < 0.00001], Gartland-Werley scores [SMD = -1.39, 95% CI (-2.24, -0.53), P = 0.001], postoperative neural in- jury [OR = 3.67, 95% CI (1.37, 9.84), P = 0.01 1 and postoperative wrist pain [OR = 0.32, 95% CI (0.13, 0.74), P = 0.008]. But no significant difference was identified in DASH scores [SMD = -0.36, 95% CI (-0.97, 0.26), P = 0.25], radiographic result assess- ment [SMD = -0.18, 95% CI (-0.53, 0.16), P = 0.3], postoperative grip strength [SMD = 0.71, 95% CI (-0.12, 1.54),P = 0.09], postoperative tendinous damage [OR = 0.31, 95% CI (0.10, 0.98), P = 0.05] and carpal tunnel syndrome [OR = 0.96, 95% CI (0.63, 1.48), P = 0.87].

CONCLUSIONCompared with radial column plate internal fixation, volar approach plate fixation for treat- ment of distal radius intra-articular fracture has advantage of recovery of joint functionand. However, the volar approach plate fix- ation was associated with a higher risk of long-term complications than the radial column approach plate fixation.

Objective To validate the hypothesis that the phenotype reversion occurs in the smooth muscle cells in the corpus cavernosum of hypertensive rats with selenium food and explore selenium′s impact on erectile function. Methods 25 14-week-old male spontaneously hypertensive rates (SHR) were divided into 2 groups (SHR-ED-Se group n = 8 and SHR-ED-N group n = 9). SHR-ED-Se rats were fed with selenium diet, SHR-ED-N rats and WKY rats with normal diet. And 10 syngeneic normotensive rats (WKY) were used as control group. All rats were killed after 4-week feeding. Immunohistochemical staining and color image analysis system were used to observe expression of α-actin, desmin and osteopontin (OPN) in rats corpus cavernosum of different group. Results 2 SHR-ED-N rats died. Expression of α-actin of smooth muscle in corpus cavernosum in SHR-ED-N group was the lowest in all groups (P = 0.000), so did erection frequency (P < 0.05). Expression of OPN in SHR-ED-N is the highest (P = 0.000). No significant difference existed in expression of desmin in all group (P > 0.05). Conclusions Phenotype modulation of smooth muscle in corpus cavernosum of SHR rats can be reversed by selenium which means the smooth cells can transform from synthetic phenotype into the contractile phenotype, resulting ultimately in improving erectile function.

Objective To investigate CT characteristics of ganglioneuroma.Methods CT findings in 12 patients with ganglioneuroma proved histopathologically were retrospectively analyzed.Results The lesions localized in the adrenal gland in 8,the retroperitoneum in 3,the posterior mediastinum in 1.eleven lesions appeared as homogeneous hypo-or isodense oval masses with well delineated margins and 1 was cysto-solid on plain CT scans.The calcifications were seen inside one tumor.On enhanced CT scans,the lesions were mild enhancement in 4,moderate enhancement in 3,significant enhancement in 3 and no enhancement in 2.Mild delayed enhancement in 5 cases,moderate delayed enhancement in 4 cases and no delayed enhancement in 3 cases were showed.Conclusion Typical ganglioneuroma shows low intensity,mild or moderate enhancement and delayed enhancement.

Objective To investigate the operative techniques for refractory cholelithiasis. Methods The clinical data of 521 patients with refractory cholelithiasis who had been admitted to People's Hospital of Hunan Province from January 1990 to December 2007 were retrospectively analyzed. Results All patients received surgery. After the operation, 3 patients died of liver and kidney failure, the remaining 518 patients were cured without severe complications. The results of B ultrasound and computed tomography showed residual stones in 78 patients (15.1%). Four hundred and twenty-three patients (81.7%) were followed up for 5 months to 17 years (mean, 7.5 years), and the rate of positive effect was 90.1% (381/423). Conclusions Most of the refractory cholelithiasis can be cured radically. Individualized surgical planning, fine and standard surgical procedure are key to the treatment effect.

Objective:To compare the content of total saponins in Paridis Rhizome from Wudang mountain area to explore the cor-relation between the quality of medicinal materials and the production areas and species. Methods: The content of total saponins in Paridis Rhizome was determined by an ultraviolet-visible spectrophotometer at 406nm with perchloric acid as the chromogenic reagent. Results:The saponins content in Paridis Rhizome from Wudang mountain area had obvious differences:the minimum was 1. 29%, and the maximum was up to 10. 22%. The content of total saponins had no obvious correlation with species, production area and altitude. Conclusion:The quality of Paridis Rhizome is unstable in Wudang mountain area, and that will affect the effectiveness and safety of the clinical medication. Only by promoting the standardized planting of Chinese medicine materials, the stable quality of Paridis Rhizo-me can be ensured.
