Background： Hamstring （HS） autograft and bone-patellar tendon-bone allograft are the most common choice for reconstruction of anterior cruciate ligament （ACL）. There was a little report about the clinical outcome and difference of arthroscopic ACL reconstruction using allograft and autograft. This study aimed to compare the clinical outcome of autograft and allograft reconstruction for ACL tears. Methods： A total of 106 patients who underwent surgery because of ACL tear were included in this study. The patients were randomly divided into two groups, including 53 patients in each group. The patients in group I underwent standard ACL reconstruction with HS tendon autografts, while others in group II underwent reconstruction with bone-patellar tendon-bone allograft. All the patients were followed up and analyzed; the mean follow-up was 81 months （range： 28-86 months）. Clinical outcomes were evaluated using the International Knee Documentation Committee （IKDC）, Lysholm scores, physical instability tests, and patient satisfaction questionnaires. The complication rates of both groups were compared. Tibial and femoral tunnel widening were assessed using lateral and anteroposterior radiographs. Results： At the end of follow-up, no significant differences were found between the groups in terms of IKDC, Lysholm scores, physical instability tests, patient satisfaction questionnaires, and incidences of arthrofibrosis. Tibial and femoral tunnel widening was less in the HS tendon autografts. This difference was more significant on the tibial side. Conclusions： In the repair of ACL tears, allograft reconstruction is as effective as the autograft reconstruction, but the allograft can lead to more tunnel widening evidently in the tibial tunnel, particularly.

Production and storage-transportation of crude oil can not only give rise to soil pollution but also destroy ecological environment. Degradation of microbes for oily soil was studied with the instnunent, Geofina Hydrocarbon Meter (GHM), by experimental analysis qualitatively and quantitatively in the paper. Analytical result showed that the crude oil could be considerably degraded by eating-oil microbes in oily soil and the number of eating-oil microbes increased while the working hours of oil-well risi...

Ulinastatin(UTI),a broad-spectrum elastase inhibitor,can stabilize lysosomal membranes and inhibit the activation and release of various inflammatory cytokines caused by cardiopulmonary bypass(CPB).[1,2]UTI has recently been considered to be an effective anti-inflammatory agent and has been widely used in clinical settings,[3-5]but the optimal dose has not been ***,we conducted a prospective,randomized,controlled trial involving 60 patients undergoing cardiac surgeries with CPB and investigated the serum levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and interleukin-8(IL-8),at different time points in order to evaluate the antiinflammatory efficacy of high-dose UTI and explore the optimum dose.
