Objective To investigate the effects of continuous passive motion (CPM) protocols on outcomes of total knee arthroplasty. Methods Seventy-two patients who underwent total knee arthroplasty were divided into 2 groups and treated with different CPM protocols: group 1 with CPM from 0 degree to 40 degrees and increased by 10 degrees per day, while group 2 with CPM from 90 degrees to 50 degrees (early flexion) and gradually progressed to full extension over a 4-day period. The CPM was administered twice a day for 1 hour over a 7-day period. All the patients participated in the same postoperative physiotherapy program. Results Group 2 (the early flexion group) had significantly more range of motion than group 1. Conclusion The early flexion can help achieve favorable functional gain after total knee arthroplasty.

Bilingual teaching is very important to the development of medical education and integration with the advance medicine knowledge in the world.Rich teaching experiences have been summarized during these years.This article summarizes the bilingual teaching experience from four parts including the concept of bilingual education,conditions of bilingual education,methods of bilingual education,results of bilingual education.We have also found some problems during teaching and worked out the improvement methods.

Objective To observe the application effect of comfortable nursing in percutaneous coronary intervention for patients with acute myocardium infarction.Methods 112 patients with acute myocardium infarction receiving the treatment of percutaneous coronary intervention were randomly divided into the observation group and the control group,each group including 56 cases.The control group was given conventional nursing,and the observation group was given comfortable nursing.Hospitalization time,nursing satisfaction degree,psychological status before and after treatment and life quality for patients in two groups were evaluated.Results The nursing satisfaction degree,nursing effect and life quality for 56 patients in the observation group were higher evidently than those in the control group.And the average hospitalization time of the observation group was lower than that of the control group.The comparison between two groups had statistical significance.Conclusions Comfortable nursing in percutaneous coronary intervention for patients with acute myocardium infarction can evidently improve medical quality,and can provide strong guarantee for the life and safety of patients.

Objective To sum up the experience of copper needle embolization for huge subcutaneous cavernous hemangioma. Methods Eighteen cases of huge hemangioma, located at the face and neck (3 cases), the upper limbs (5 cases), or the lower limbs and buttocks (10 cases), respectively, were treated from 1996 to 2003. Needles made from copper wire 1~3 mm in diameter were inserted into the lesions, through the skin directly or under the guidance of color Doppler ultrasonography. The copper needles were left in place for 1 week, with or without 4~6 V direct current circulated for 5~10 min twice. Results The therapeutic outcomes included: the shrinking and sclerotization of the hemangioma with the disappearance of postural changes (18 cases), the decrease of circumference of the involved limb (13 cases), the change of the lesion skin from blue-purple to light or normal in color (4 cases), the subsidence or disappearance of swelling and heavy feeling of the involved limb (5 cases), and the regression of the lesion and the reduction of blood flow under color ultrasonography (14 cases). Conclusions Copper needle embolization is a simple, effective and relatively less invasive method for the treatment of huge subcutaneous cavernous hemangioma that is difficult to be resected. It at times may be the only applicable option for children.

Objective: To analyze some influence factors during isokinetic eccentric test. Method: Twenty normal males were tested by Biodex isokinetic test and rehabilitation system. Their peak torque(PT) and peak torque to body weight (PT/BW) were analyzed under different conditions. Result: It was found that velocity and contraction mode influence the results significantly( P＜0.01). Conclusion: Many factors must be considered during isokinetic eccentric test and training.

20 normal males were examined by BIODEX isokinetic test and rehabilitation system,and data collected were used to observe the influence of angle and time on the isokinetic concentric constriction of knee joint. It was found that angle and time, especially angle factor obviously affected the testing results.

The suppressive effect of anti-KDR antibody against VEGF on proliferation of hemangioma-derived vascular endothelial cells (HVECs) was investigated. HVECs from one case of hemangioma in proliferative phase were cultured. Both primary culture and sub-culture were conducted in M199 medium. The HVECs of passage 3 were divided into 4 groups based on the concentrations of anti-KDR antibody. Cell count was performed and inhibitory rate of HVECs was measured before and 9 days after interference. The results showed that the number of HVECs in the anti-KDR antibody-treated groups was significantly decreased and the inhibitory rate of HVECs by anti-KDR antibody (50, 10 and 2 microg/mL) was 84%, 63% and 39% respectively at 9th day after interference, with the difference being significant. In the control group, the number of HVECs was increased significantly. In was concluded that the anti-KDR antibody could suppress the activity of VEGF through blocking the KDR, indicating the potential clinical applications of anti-KDR antibody in the treatment of hemangioma.

Objective To summarize clinical experience of reconstruction of breast suspensory structure in correction of mild-to-moderate breast ptosis.Methods Through a periareolar incision,the flabby deep layer of the superficial fascia beneath the upper breast gland was completely removed.Then the gland was lifted up to the normal position and the superior pole of the gland was fixed to the pectoral fascia at the second intercostal space.By using the dermal bra technique,an appropriate amount of skin was excised,and the dermis was fixed to the anterior surface of the breast gland. Or a monofilament polypropylene mesh was implanted and fixed to the anterior or posterior surface of the upper breast gland.Postoperatively,remarkable scar fibrosis reaction developed to form strong supporting structures just like natural ones.Glandular plication or implant augmentation was simultaneously employed to enhance the projection,if necessary.Results A total of 32 cases of mild-to-moderate breast ptosis was treated with this technique,including 10 cases of mastopexy only,20 cases of mastopexy with implant augmentation,and 2 cases of mastopexy using monofilament polypropylene mesh.The operation time was 90~150 min(mean,110 min).The intraoperative blood loss was 30~100 ml(mean,58 ml).No complications such as nipple or areola necrosis or sensory disturbance were found.Follow-up observations for 6~12 months(mean,11.3 months) showed a satisfactory rate of 90.6%(29/32).Conclusions Reconstruction of breast suspensory structure is a simple,safe,and effective method for correction of mild-to-moderate breast ptosis without hyperplasia of mammary glands.
