Objective To report arthroscopic reconstruction of anterior cruciate ligament (ACL) with iliotibial tract autograft and gracilis tendon by Moriya s method and to evaluate its clinical results. Methods The iliotibial tract autograft of about one third length was dissected with the tibial attachment kept. Then the trimmed gracilis tendon was wrapped in the iliotibial tract to reconstruct ACL. 16 patients (12 males and 4 females) were treated in this way. The anterior drawer test and the Lachman s test were all positive before operation, indicating that anteromedial and posterolateral bundles of ACL were totally broken, which was proved by arthroscopy. Results All patients were followed up for 4 to 17 months (mean 9 months). According to the criteria for knee ligament function evaluation set up by Japanese Association of Orthopaedics( JOA) , 10 patients scored ≥ 90 points, 5 patients 80 to 90 points, and 1 patient ≤ 80 points.The excellent and good rate was 93.75% . Conclusion Iliotibial tract autograft transfer with gracilis tendon to reconstruct ACL under arthroscopy boasts convenience in harvesting grafts, simplicity in performance and excellent results, without evidence of damaging extension and flexion tendons of the knee or causing patellofemoral pain.

AIM The purpose is to study the anti-arrhythmic effects of extracts from cultured Cordyceps sinensis. METHODS Aconitine and barium chloride were used to induce experimental arrhythmia models in rats. RESULTS The results showed that PE was more potent than other ingredients. Pretreatment with PE by oral administration significantly antagonized arrhythmia induced by aconitine. PE significantly prolonged the onset of arrhythmia, decreased the duration and diminished the degree of severity. And in barium chloride-induced arrhythmia model, PE had some anti-arrhythmia effect,which could diminish the degree of severity effectively to some extent. CONCLUSION PE is an active component to antagonize arrhythmia induced by aconitine and barium chloride.

Objective To study the influencing elements in x-Gal staining method and optimize the reactive conditions so that nonspecific background can be eliminated and grafted exogenous cells carrying LacZ gene can be discerned correctly. Methods C17 2 cells (carrying lzcZ gene) were injected into the right lateral ventricle both in the adult and newborn animals. After one week they were perfused using two methods, then the slices were stained at different pH and incubating time respectively. The X-gal positive cells in hippocampus were counted under light microscope. Results Background staining in this method has close correlation with the species and age of the host animals and it decreases when pH is higher or incubating time is shorter. The results are the best when pH 9 5 and the incubating time is 1*!h.Conclusion The reliability of X-gal staining method depends on optimization of several parameters, including pH, incubating time, perfusion etc. It is necessary to establish the correspondent controls.;
