Objective To design an arthroscopic universal aiming device for cruciate ligament repairing and evaluate its clinical efficacy. Methods The aiming device was designed on the principle of “a line crossing any point on a spherical surface and perpendicular to it must cross the sphere center”, which enables the surgeon to locate the ligamentous attachment of cruciate ligament precisely for reconstruction. Twelve cases of PCL injuries have been treated with this method. Results The average follow up period was 12.1 months (5-19 months). According to Lysholm scoring system, the average score was improved from 59.2 points to 92.7 points, increased by 33.5 points. Lachman test turned negative in all patients, the average range of motion was 120?. Conclusion The instrument was reasonably designed for easy handling and precise orientation. It is particularly preferable to locate the tibial attachment of cruciate ligament for endoscopic reconstruction on the posteromedial approach.

Zhejiang province takes an innovative approach in its rural health service strategy featuring routine health examination,which proved an initial success.Intending to assess the effect and dilemma of such a system,and seek sustainable development in future,we made investigations in Pinhu and Xianju in Zhejiang province.Overall,rural health service strategy based on rural health routine examination,to some extent, improved patient-physician relationship,changed and strengthened their rural health concepts,and upgraded non-communicable disease control. Furthermore,the practice has economically and socially influenced rural health service institutions and rural physicians in terms of their concepts and methodology.There are also setbacks and problems in need of govemment support,programme improvement and resource optimization for further sustainability.

Objective We investigate lipid peroxidation of compressed myeloid tissue at early stage after decompression of chronic compressive spinal cord injury.Method SOD and MDA of compressed myeloid tissue are measured respectively before compression,before decompression and 3h after decompression.Result Increased MDA while decreased SOD of compressed myeloid tissue at 3h after decompression than before decompression.Conclusion The increased lipid peroxidation of compressed myeloid tissue at early stage after decompression of chronic compressive spinal cord injury.It is possible that it was resulted from ischemical reperfusion injury.

ObjectiveTo compare the effect of the neurosurgical clipping and endovascular for treating intracranial aneurysm.MethodsRetrospectively analyzed the clinical data of 110 cases with intracranial aneurysms.The patients were divided into intervention group(55 patients with endovascular treatment) and surgery group(55 patients with neurosurgical clipping treatment) according to different methods,followed forup 1 ～4 months,and immediately evaluated the efficacy.The Chinese stroke scale(CSS) and activities of daily living(ADL) score were used for prognostic evaluation.ResultsThe immediate effect:the marked efficacy in 40 cases,efficacy in 10 cases and inefficacy in 5 cases,and the total effective rate in the intervention group was 90.9％,while the surgery group were 32 cases,10 cases,13 cases,and the total effective rate was 76.4％.There was significantl differences between the two groups ( x2 =3.96,P ＜ 0.05 ) ; the CSS and ADL scores significantly lower than pre-treatment ( t =9.12,8.05,P ＜0.05).ConclusionEndovascular treatment for intracranial aneurysms could improve the clinical efficacy and improve patients self-care ability,and significantly improve the prognosis.
