Objective To investigate the anterior trans-injured vertebral short segment limited fixation and fusion in treating thoracic and lumbar spinal tuberculosis.Methods One hundred and three patients with spinal tuberculosis from 2010 to 2012 were operated by trans-anterior approach(trans-thoracic above thoracic spine 12,trans-retroperitoneal below waist spine 1)tuberculosis focus clearance and spinal canal decompression,intervertebral bone graft of vertebral structure,and short segment internal fixation for residual disease spine.Results The nerve function of the patients was effectively improved after surgery,and the imaging re-sults showed that the average lesion kyphosis angle was significantly decreased(P <0.05).The postoperative follow-up found that the bone graft was fused after half a year,and the average local kyphosis angle was still 13°,which had no obvious change compared with that after operation.In addition,the internal fixation position had no looseness and fracture,the grafted bone had no displace-ment and detachment,the four limbs movement was normal without local percussion pain or tenderness.Conclusion The anterior trans-injured vertebral short segment limited fixation and fusion has the satisfactory short term clinical efficacy in the treatment of thoracic and lumbar spinal tuberculosis.

Objective To understand the actual situation of community‐based diabetes management and analyze common prob‐lems in diabetes management and find the solutions to diabetes management though the objective investigation .Methods The pa‐tient′s data including gender ,age ,education ,medication ,lifestyle information were collected by household face‐to‐face survey and were performed a single factor χ2 analysis of relevant indicators .Results Relative to the patients with middle school education only and is less than 3 000 a month ,the diabetic patients who ere above the junior middle school and family income equal to or greater than 3 000 had good diabetes management on medication ,diet ,exercise ,blood glucose monitoring ,diabetes related knowledge .Con‐clusion Patient′s education and economic level could effect attitudes toward diabetes ,medication ,diet ,exercise ,blood glucose moni‐toring ,diabetes‐related knowledge .

【Objective】 To analyze the cost and effectiveness of different HIV screening strategies based on multi-center HIV residual risk study, so as to provide reference for blood centers to adopt appropriate HIV testing strategies. 【Methods】 According to the HIV screening and confirmation of blood donors in three blood centers in Anhui Province, the residual risk of different HIV screening strategies was estimated. A decision tree model was established to analyze the cost-effectiveness differences of three different screening strategies under current domestic policies. 【Results】 The residual risk of anti-HIV-1 +2 ELISA, HIV Ag/Ab1+2 ELISA and ELISA+NAT were 1.17×10^-6,0.84×10^-6 and 0.59×10^-6, respectively. According to decision tree model analysis, HIV Ag/Ab1+2 ELISA had a cost-effectiveness advantage over anti-HIV 1+2 ELISA when there was no NAT, but the advantage of HIV Ag/Ab1+2 ELISA disappeared when there was one NAT. The cost of HIV reagents, the cost of HIV treatment and the cost of false positive discarding were sensitive factors of the model. 【Conclusion】 In this area, one anti-HIV 1+2 ELISA combined with one NAT has a cost-effectiveness advantage. Blood centers need to confirm and evaluate the ELISA reagents used before conducting HIV screening. Under the premise of ensuring sensitivity, reagent cost and reagent false positive rate are the key factors.
