AIM:To investigate the association of obesity and elevated alanine aminotransferase with insulin resistance and compare these factors with metabolic syndrome. METHODS:We enrolled a total of 1308 male workers aged from 22 to 63 *** was extracted from the workers'periodic health check-ups in *** cases were from the community of northern Taiwan. This was a cross-sectional observational study from July to September in *** grouped all cases into four groups,based on the quartile of homeostasis model *** top fourth quartile group was defined as the group with insulin *** performed multivariate logistic regression analysis for the odds ratio of the risk factors for insulin resistance. RESULTS:Compared with metabolic syndrome,the coexistence of both factors had a 4.3-fold(95%CI: 2.7-6.8)increased risk,which was more than metabolic syndrome with a 3.6-fold(95%CI:2.6-5.0)increased *** two factors had a synergistic *** synergistic index of obesity and elevated alanine aminotransferase(ALT)was 2.1(95%CI:1.01-4.3).CONCLUSION:Obesity and elevated ALT are associatedwith insulin *** effects are synergistic. Coexistence of them is better than metabolic syndrome in predicting insulin resistance.

The charged lepton flavor violation process is a clean and sensitive probe of new physics beyond the Standard Model. A sensitivity study is performed to the process τ^-→γμ^- based on a 3 fb^(-1) inclusive Monte Carlo sample of e^+e^- collisions at a center-of-mass energy of4.26 or 4.6 Ge V, in the framework of the BESIII software system. The 90 % confidence level upper limits on B(τ^-→γμ^-) are estimated assuming no signal is produced. We also obtain the sensitivity on B(τ^-→γμ^-) as a function of the integrated luminosity, to serve as a reference for the HIEPA being proposed in China. It is found that 6.34 ab^(-1) are needed to reach the current best upper limit of 4:4 10^(-8) and about 2510 ab^(-1) are needed to reach a sensitivity of 10^(-9) if the detector design is similar to that of BESIII.

Objective： To introduce and characterize the modified biplanar opening high tibial osteotomy with rigid fixation to treat varus knee in young and active patients. Methods： Between June 2001 to July 2008, 18 patients with monocompartmental degeneration of the knee combined with a varus malalignment of the leg had the modified biplanar opening high tibial osteotomy and the osteotomy was fixed with the locking plates （Locking Compression Plate System）. The mean varus deformity before operation was 11.5° （5°- 19°） and no degenerative changes were found in other departments. Stability of the knee was normal in 15 patients, but ruptures in anterior cruciate ligaments or lateral collateral ligament were presented in the remaining 3 patients. Preoperative symptom was mainly limited in the pain of medial compartment. The preoperative and follow-up data for the range of motion and Lysholm score were determined. Subjective satisfactory examination was also applied to the patients for the operation they selected. Results： All of the patients were followed up with an average of 32.5 months （12-82 months）. There was no ununion or delayed union in this group during the follow-up period. No complications like broken plate, nerve injury, or blood vessel injury occurred. The postoperative average corrected degree was 9.5° （5.5°-18°）. No degenerations developed in the three departments of the knee. The Lysholm scores before and after surgery were 42.5 and 77.5, respectively （P〈0.01）. The overall fineness rate was 83.3%. The subjective satisfactory survey demonstrated that about 83.3% patients showed satisfactory on the operation. There was no obvious difference in the range of motion before and after operation, but significant changes were found in the Lysholm score and varus degree from preoperative to follow-up. Conclusion： Proximal opening high tibial osteotomy performed in conjunction with the special rigid locking plate yielded good results for symptomatic genu varum. This new cl
