Objective To investigate the effect of Hedysarum Polybotys saccharide(HPS)on insulin resistance rats.Methods The model of type 2 diabetic-insulin resistance rat was successfully made by STZ and high caloric diet.Then the rats were intervene by Metformin(MT)and HPS.Results Compared with the model group,the level of blood glucose,INS and CP were lowered,ISI were improved and FFA were restrained by HPS.Conc(?)sion HPS can reduce the insulin resistance in multiple ways.

Implant-related infection is a commonly occurred complication in orthopaedics. The surface modification methods frequently used for anti-infection of implant surface were minimizing bacteria adhesion,grafting antibacterial agents and improving osteointegration. The pathogenesis and characteristics of orthopaedic implant-related infection and the research advances in the surface modification of orthopaedic implants for anti-infection are described in this paper,providing a reference for the research of novel implants with anti-infection characteristics.

Background Retinopathy of prematurity is mainly due to retinal neovascularization.Objective This laboratory work was to evaluate the efficacy of different dosage of avastin for inhibiting retinal neovascularization.Methods Ninety 7-day-old clean C57BL/J6 mice were randomized into six groups as follows:air control group,hyperxia control group,hyperxia BSS group and avastin groups.C57BL/J6 mice in air control group were raised in regular air environments.The fifty mice were fed under the environment with 75％ ±2％ oxygen for 5 days to establish the retinal neovascularization models.The 1.25,2.50 and 5.00 g/L avastin (0.5 μl) were injected inteavtreally in forty-five mice models as low,moderate and high dosage avastin groups respectively,and 0.5 μl BSS was used at the same way in fifteen models as hyperxia BSS group.The mice were sacrificed in the 17-day-old age using excessive anesthesia method and the retina sections were prepared for the calculation of the numbers of vascular endothelial cell nuclei broken retinal inner membrane after hemotoxylin and eosin staining.The expression of CD34 in the retina was detected by immunochemistry.The morphology and distribution of retinal neovascular vessel in various groups were observed using retinal flat.The use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The numbers of cell nuclei broken the inner limiting membrane was significant increased in the hyperxia group compared with the air control group( P＜0.01 ),and those in difference doses of avastin were considerably reduced in comparison with hyperxia BSS group (P＜0.01) and hyperxia group (P＜0.01 ).The decrease of numbers of cell nuclei broken the inner limiting membrane was obvious in low dose of high dose of avastin compared with low dose of avastin (P＜0.05 ).CD34 was positively expressed in retina internal membrane of hyperxia group.Retinal flat revealed the regular distribution and normal structure of retinal vessels in air control group and avastin groups.However,retinal and vitreous cavity neovascularization,leakage and enlarged non-perfusion regions in the perimeter of the retina were seen in hyperxia group and hyperxia BSS group. Conclusions Intravitreal injection of avastin can arrest retinal angiogenesis in oxygen-induced retinal neovascularization models in a dose-dependent manner.

Objective To analyse the sensitivity ,specificity and coincidence rate of genechip method in the detection of resistance to antibacterial agents in Mycobacterium tuberculosis(MTB) ,in order to provide a convenient ,accurate and rapid method for detec‐ting antibacterial resistance in MTB .Methods The DNA sequencing was taken as gold standard ,and antibacterial resistance of the strains of MTB isolated from sputum specimens of 250 cases of patients with tuberculosis from August to December 2014 were de‐tected by using the genechip method and proportion method for susceptibility testing at the same time .Efficacies of the two methods in detecting MTB resistance to rifarnpin and isoniazid were compared .Results The MTB resistance rate to rifarnpin detected by u‐sing the genechip method and proportion method for susceptibility testing was 3 .0% and 3 .5% respectively ;that to isoniazid was 6 .7% and 8 .2% respectively .For detecting M TB resistance to rifarnpin and isoniazid ,the DNA sequencing was taken as gold standard ,the sensitivity ,specificity and coincidence rate of genechip method was higher than those of proportion method for suscep‐tibility testing ,and the test time of genechip method was shorter than that of proportion method for susceptibility testing ,there were statistically significant differences(P<0 .05) .Conclusion Using the genechip method to detecting MTB resistance to rifampin and isoniazid has high sensitivity ,specificity and coincidence rate ,which could replace the proportion method for susceptibility tes‐ting and become an effective method .
