Objective To explore the relationship between big-five personality,and public mood of volunteers,and to find out the moderator effect of justice sensitivity.Methods A total of 1 022 volunteers were investigated.The Big-Five Inventory (BFI),Public Mood Scale (PMS),Justice Sensitivity Inventory (JSI) were applied to all subjects.Results The average score was (19.77±4.49) for extraversion,(26.69± 4.13) for agreeableness,(23.33±5.37) for conscientiousness,(12.49±4.91) for neuroticism,(24.95±5.44)for openness,(8.78±3.23) for positive public mood,(3.46±3.06) for negative public mood and correlated with (26.85± 10.55) for observer sensitivity.The extraversion,agreeableness,conscientiousness and openness were correlated with positive public mood(β=0.31,P＜0.01;β=0.25,P＜0.01;β=0.29,P＜0.01;β=0.26,P＜0.0 1),and negatively correlated with public mood (β=-0.14,P＜0.01;β=-0.29,P＜0.01;β=-0.20,P＜0.01;β=-0.08,P＜0.01).Neuroticism was negatively correlated with positive public mood (β=-0.27,P＜0.01),and positively correlated with negative public mood (β=0.31,P＜0.01).The interaction effect of agreeableness and observer sensitivity negatively correlated with positive public mood,negative public mood (β=-0.09,P＜0.01;β=-0.07,P＜0.05).The interaction effect of neuroticism and observer sensitivity was positively correlated with positive public mood (β=0.08,P＜0.01).Conclusion Observer sensitivity plays a regulative role between big-five personality and mental health,and can slow the negative impact of low agreeableness to positive public mood,strengthen the impact of low agreeableness to negative public mood,and slow the negative impact of high neuroticism to positive public mood.

Objective To study the role of cover-stent and embolization in the treatment of hepatic artery pseudoaneurysm following liver transplantation.Methods 5 patients with hepatic artery pseudoaneurysm after liver transplantation were treated with cover-stent and embolization between May 2010 and July 2013.The clinical features,imaging findings and complications were reviewed.Results All the 5 patients with hepatic artery pseudoaneurysm were successfully treated.2 patients with intrahepatic pseudoaneurysm received embolization.Of the 3 patients with extrahepatic pseudoaneurysm,2 received cover-stent treatment,and 1 patient received embolization.No complications related to the interventional treatment were encountered.2 patients died from multi-organ failure one month after the interventional treatment.Conclusion Cover-stent and embolization were effective and safe to treat patients with hepatic artery pseudoneurysm following liver transplantations.

Objective To investigate the effect of a novel lymphotoxin with selectively binding to p55 tumor necrosis factor receptor (p55TNFR) on myocardial ischemia-reperfusion injury in rats in order to explore the mechanism.Methods A total of 40 SD rats were randomly (random number) assigned into four groups (n =10 in each),namely sham operation group (group A),I/R group (group B),wild type rhLTα treatment group (group C),and p55TNFR selective rhLTα (rhLTα-Q107E) treatment group (group D).After I/R model rats were established,various therapeutic agents or saline were given by continuous intravenous infusion for 24 h via a micropump.After 24 hours of treatment,serum myocardial zymogram,such as aspartate aminotransferase (AST),lactate dehydrogenase (LDH) and creatine kinase (CK),as well as superoxide dismutase (SOD),malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) activities were determined.Myocardial infarction size (MIS) was measured by nitro blue tetrazolium chloride (NBT) staining.Results Compared to sham operation group,MIS,AST,LDH,CK,MDA were increased,while the activities of SOD and GSH-Px were decreased.However,all the effects were significantly reversed by treatment with rhLTα-Q107E (P ＜ 0.05) but not rhLTα (P ＞ 0.05).Conclusions The rhLTα-Q107E plays a role in the protection against myocardial ischemia-reperfusion injury in rats by the mechanism of scavenging oxygen free radicals and increasing the activity of endogenous antioxidant system.

Objective To observe the efficacy of Mimics finite element analysis software in the gasserian ganglion radiofrequency treatment of trigeminal neuralgia. Methods 180 cases with primary trigeminal neuralgia and VAS score ≥8 were randomly divided into 2 groups (n = 90 each): CT group (group C) and Mimics group (group M). The preoperative skull CT image of the foramen of cranial base could be analyzed in group C. The preoperative cranial CT image could be reconstructed and analyzed by Mimics finite element analysis software in group M. The puncturing success rate, complications rate and the outcomes between two groups were recorded. Results The puncturing success rates were 100% in group M and 92% in group C (P < 0.05). 6 cases with hematoma and 1 case, which were stabbed into the oral cavity were found in group C. No puncture complication was found in group G. There was no statistically significant between the two groups (P < 0.05). The VAS score was 1.6 ± 0.3 in group C and 1.3 ± 0.4 in group G, there was no statistical significance (P > 0.05) between them. Conclusions The Mimics finite element analysis software could improve the success rate of basicranial foramen ovale puncture and reduce the occurrence rate of puncture complications. Therefore , it could be safely applied to the treatment of primary trigeminal neuralgia by gasserian ganglion radio frequency.

AIM:To investigate the effects of resveratrol ( Res) on the proliferation of ARPE-19 cells and to ex-plore the possible mechanisms.METHODS:After ARPE-19 cells were treated with Res at concentrations of 0, 50, 100, 150, 200 and 300 μmol/L for 24 h, 48 h and 72 h, the effects of Res on the proliferation of the cells were tested by CCK-8 assay.The ARPE-19 cells were treated with Res at concentrations of 0, 100, 150 and 200 μmol/L for 48 h.The effects of Res on the cell cycle and apoptosis were detected by flow cytometry with Annexin V-FITC/PI staining.The protein expression of proliferating cell nuclear antigen (PCNA) was detected by immunofluorescent assay.The mRNA expression of PCNA, P21 and P27 was determined by real-time PCR.RESULTS:The results of CCK-8 assay showed that Res inhibited the prolifera-tion of ARPE-19 cells in a time-and dose-dependent manner.The treatment with Res for 48 h resulted in an arrest of cell cycle at S phase without increasing cell apoptosis.Res inhibited the protein expression of PCNA in ARPE-19 cells.The re-sults of real-time PCR showed that Res increased the mRNA expression of P21 and P27, and decreased the mRNA expres-sion of PCNA.CONCLUSION: Res inhibits the proliferation of ARPE-19 cells and induces the cell cycle arrest at S phase.The mechanism may be related to up-regulation of P21 and P27, and down-regulation of PCNA.

Objective To evaluate the therapeutic effectiveness of percutaneous endovascular treatment of hepatic venous outflow obstruction (HVOO)after pediatric liver transplantation(LT).Methods From January 2008 to January 2013,10 children with obstruction of hepatic vein (HV) or inferior vena cava (IVC) anastomosis underwent percutaneous transluminal angioplasty (PTA) with balloon dilation or stent placement.The hepatic venous outflow obstruction occurred 10-455 days (median,125 days) after pediatric liver transplantation.According to the time of obstruction,the obstruction was divide into early onset (＜1 month) and late onset(＞1 month).The effectiveness of PTA was analyzed.Results Twenty-one procedures were performed.One treatment was ineffective,and technical and initial clinical success ratio was 95.2％ (20/21) and 70.0％ (7/10),respectively.In 3 cases with early onset after LT,operation was performed after unsuccessful PTA in 1 case.One patient who developed recurrent stenosis was treated with PTAS.The other patient died of acute rejection.Late onset after LT was found in 7 cases,who were treated with PTA or stent successfully.Conclusions In cases of venous outflow obstruction resulting from HV and/or IVC lesions after pediatric liver transplantation,percutaneous endovascular treatment with balloon dilation or stent placement is a safe and effective alternative treatment that results in midterm and long-term patency.Early-onset or hepatic veins combined with superior vena cava obstruction should be implanted with stents as early as possible.Late-onset or hepatic veins obstruction alone can be get better results with Balloon Dilatation.

Objective To investigate the early outcomes of reconstruction of severe acetabular bone defects by the use of tantalum trabecular metal cup combined with tantalum augment in total hip replacement.Methods From April 2014 to December 2015,23 patients (24 hips) underwent total hip arthroplasty by the use of tantalum trabecular metal cups combined with tantalum augments.There were 11 males (12 hips) and 12 females (12 hips),with the average age 54 years (range,38-65 years).We tried to reconstruct an annular support for the cup.If an annular support cannot be reconstructed,the cup obtains primary stability based on the three point fixation rationale.Flexible placing of the TM cup combined with the augments helped reconstruction of the socket ring or supporting points,thus achieving rigid primary stability of the cup and restoring center of rotation.Harris hip score and Western Ontario and McMaster Universities (WOMAC) osteoarthritis index score were recorded.Any severe intraoperative complications including vascular or nerve injury and severe postoperative complications such as periprosthetic joint infection,dislocation or periprosthetic fracture were reported.The vertical position of the center of rotation from the interteardrop line and the horizontal position of the center of rotation from the teardrop were measured and analyzed.Results The average follow-up duration was 16 months (range,7-28 months).The mean Harris hip score was 35.3±12.1 preoperatively and 82.7±8.3 postoperatively (t=-16.991,P＜0.001).The mean WOMAC score was 39.1 ±24.0 preoperatively and 87.2± 11.4 postoperatively (t=-7.671,P＜ 0.001).The average vertical location of the center of rotation was 44.02± 11.65 mm preoperatively and 22.96±8.24 mm postoperatively.All the tantalum cups and augments were stable.There was no periprosthetic joint infection,dislocation,nerve injury or periprosthetic fracture.Conclusion Reconstruction of Paprosky Ⅲ acetabular bone defects by the use of tantalum trabecular metal cup combined with tantalum augment can achieve good primary stability and restore the center of rotation with almost normal hip biomechanics.The short-term outcomes are satisfied.
