Objective To explore the general characteristics of the psychological sub-health state and to analyze the factors pos-sibly leading to the psychological sub-health state in order to provide the scientific basis for the treatment and prevention of the psy-chological sub-health state .Methods The individuals with the physical examination in our hospital were performed the psychologi-cal heath survey .Among them ,1 712 cases of psychological sub-health were taken as the research group and contemporaneous 1 902 cases of normal health were taken as the control group .The Symptom Check List-90(SCL-90) was adopted to compare the two groups and the logistic regression analysis was adopted to analyze the risk factors possibly leading to the psychological sub-health occurrence .Results The average scores of 20 factors in SCL-90 in the research group were higher than those in the control group , the difference was statistically significant (P<0 .05) ,in which ,the scores of interpersonal relationship sensitivity (22 .1 ± 5 .7) ,para-noid(14 .1 ± 5 .2) and the others(17 .5 ± 6 .3) in the research group were significantly higher than the critical scores with obvious symptoms .The logistic regression analysis results showed that :the sleep quality(OR=1 .843) ,accidental injury(OR=2 .634) ,eco-nomical status(OR=3 .032 ,and professional type(OR=4 .684) were the independent risk factors of the psychological sub-health occurrence .Conclusion The local patients with psychological sub-health were more prominent in the more sensitivity of the inter-personal relationship ,paranoid and poor sleep ,especially the intellectuals ,individuals with poor sleep and the crowd with accidental injury are prone to develop psychological sub-health .

Objective Lateral dislocation of the patella pulled laterally from the trochlea and across the lateral femoral condyle,was often a transient phenomenon with spontaneous reduction,diagnosis based on the results of physical examination and clinical history was difficult.The present was in an effort to explore the mechanism and definition of acute patellofemoral dislocation as well as assessment with MRI of the injury.Methods From May2001to July2002,34patients aging from11to25years with18males and16females,had a history of knee joint,28of which were experienced a twisting injury with the knee in flexion and internal rotation of femur on a fixed foot.Sagital,coronal and transverse MRI were performed with T 1 WI,T 2 WI,STIR and TSHIRT sequences.The manifestations of MRI were analyzed retrospectively,and clinical data,X-ray films,CT scan and the findings of arthroscopy were studied as well.Results All of34cases injured were found the signal intensity abnormalities of subchondral bone in the inferior medial part of patella and the anteri-or lateral part of lateral femoral condyle,which suggested that bone was injured.MRI findings of cartilage fis-sure at medial patella were found in20cases and injury of the patella retinaculum was seen at MRI in27cas-es.MRI findings revealed joint effusion in all patients,and lateral subluxation of the patella was seen at MRI in23cases.Conclusion The resultant jury on MRI findings of acute patellofemoral joint dislocation caused by a-cute impingent of patellar medial facet to lateral femoral chondyle at the various degree of flexion and rotation of the knee include the osteochondral fracture in the inferior medial part of patella,the anterior lateral part of lateral femoral condyle,the subluxation or dislocation of patella,the injury of medial patella retinaculum and the joint effusion.MRI could be helpful for the diagnosis of the disease,and demonstrate the location and ex-tent of injury on the different compartments of the involved knee.

Objective To study the retrieved human allografts pathologically in order to probe into the histological changes of implanted allograft. Methods The specimens were retrieved from seven cases between February 2003 and March 2004, and the allografts had been in situ from two to 16 months. Of seven cases, four were diagnosed primarily as malignant fibrohistocytoma of proximal humerus, osteosarcoma of femoral shaft, bone giant cell tumor of distal femur and bone giant cell tumor of proximal tibia each, which were treated with wide resection of tumor and massive allograft transplantation and internal fixation of plate or inter-locking nail; two were open comminuted fracture of distal femur, treated with massive allograft transplantation and internal fixation, underwent autograft bone transplantation because of united massive allograft, had a punch biopsy of allografts for observation; one was tibial open fracture being fixated with inter-locking nail and small segment allograft transplantation, sustained infection at two weeks after primary operation and underwent debriment, removal of internal fixation and external fixation. Results Of seven cases, five were found with bone absorption radiographically, and were classified into three types:1)sever bone absorption; 2)bone absorption associated with sinus and effusion of the wound; 3)bone absorption accompanied by pyogenic infection. The later condition was caused by bacterial infection without a relationship of allograft. And the former two conditions could be classified into two subtypes: 1)osteoclastic absorption, which was followed by new bone formation; 2)inflammatory absorption, which was found with infiltration by round inflammatory cell, preponderantly lymphocytes, and mononuclear phagocytes with few osteoclasts, osteoblasts or new bone formations. Moreover, in sever bone absorption, vascular lesions such as vasculitis, swelling of endothelial cells or proliferation changes in the vessels, and obliteration of the arteries. Conclusion An intensive infiltration accompanied by vascular lesions may be the evidences of histological changes suggestive of an immune reaction directed against the grafts, and the failure of the clinical outcomes.

Objective To explore the diagnostic value of MRI in tumor of soft tissue. Methods The MRI manifestations of 180 soft tissue tumors dating from October 2001 to August 2004 were retrospectively analyzed, they were all confirmed by pathology. All cases were examined with Picker 0.23 T MRI. Fast spin echo(FSE)T1 and T2-weighted sequences and short tau inversion recovery (STIR/TSHIRT) fat-suppressed sequences were commonly used. MR examinations were performed at least in two of coronal, sagittal, axial planes. Of 180 cases, there were 62 vascular tumors, 34 giant cell tumor of tendon sheath, 26 neural tumors, 23 lipomas, 18 fibrous tumors; 17 malignant tumors including 7 of malignant fibrous histiocytoma(MFH), 3 of malignant lymphomas, 2 of liposarcoma and one each of chondrosarcoma, myofibrosarcoma, melanoma, facial sarcoma and leiomyosarcaoma. 10 cases were of tumor-like lesions, including 2 of myositis ossificans, 8 of fat necrosis. GCT of tendon sheath (33/34 cases), hemangiomas (23/52 cases) were common in hands and feet. MFH often involved legs and upper arms(4/7 cases, 3/7 cases). The tumors in the groin were mainly malignant(4/5 cases). Results The ratio of benign to malignant tumors was 9∶1. Tumors showed isointensity or hypointensity in T1WI and hyperintensity or mainly hyperintensity but mixed signal in T2WI. The diameter of benign tumors was 1-18 cm, the malignant was 4-10 cm. The tumors were lobulated, oblong or irregular in shape. 12 invaded to bone, 28 involved to neurovascular system. Some body parts were easily involved because of different histologic component. Conclusion The MRI for soft tissue tumors is highly sensitive. The location and some characteristical signs are useful for diagnosis, whereas the size of the lesion, the degree of border smoothness and the signal intensity are not certain for the diagnosis.

Objective\ Treatment of spondylolisthesis using freeze dried femoral ring allografts plus morselled cancellous autografts (called as composite cortical ring) by anterior lumbar interbody fusion (ALIF). Methods\ Fourteen patients were treated by this procedure, there were six males and eight females. The age of the patients range from 40 to 56(average 46). Ten segments were of grade Ⅱspondylolisthesis, five segments were of gradeⅠ. Ten patients were treated with RF as internal fixation, four patients with short Harrington rod as internal fixation. Results\ The fusion rate and clinical results of ALIF were analyzed by comparing the findings on the X-ray films taken preoperatively and 6 months postoperatively as well as by JOA score. The fusion rate of 15 segments of 14 patients(two segments of 1 patient was fused) is 85.7%, the average improvement rate of JOA score is 73.3%at an average follow up of 26.6 months. Conclusion\ ALIF with composite cortical ring could successfully restore the spinal structure, maintain the interspace height distracted intraoperatively, obtain high fusion rate and excellent clinical results.\;
