Objective To study the etiology,clinical presentation,MR images,treatment and prog-nosis of spontaneous spinal epidural and subdural hematoma.Methods From1995to2002,6cases diag-nosed as spontaneous spinal epidural and subdural hematoma were reviewed retrospectively.All of the pa-tients were males aging from30to68years with an average of 47years.The onset was acute while the pa-tients were in resting or light activity without prior history of any infection,administration of drugs or trau-ma.One patient had the history of hypertension,and another one was found to have diabetes after admission.The clinical characteristics were sudden pain involving neck,shoulder,chest and back,then dysfunction of motion and sensation of extremities and sphincter within few minutes.4cases of spontaneous spinal epidural hematoma were located at T 5~6 ,T 2~4 ,C 4~5 and C 6 ~T 1 respectively,and2cases of spontaneous spinal subdu ral hematoma at C 7 ~T 1 and C 7 ~T 2 respectively.Results All cases were proved with surgery and pathology.MR imaging showed occupying mass in the posterior or posteriolateral region inside the spinal canal.T 1 -weighted imaging was most useful owing to its typical signal changes with the hematoma.T 2 -weighted gra-dient echo sequence was capable to identify epidural and subdural spinal hematoma.Total laminectomy and hematoma debridement were performed.The outcome was closely related to the interval between the onset and surgery.The patients were followed up from6to18months with an average of 10months.All cases showed no significant improvement of spinal cord function except 5cases with incomplete recovery of sphincter function.Conclusion Spontaneous spinal epidural and subdural hematoma are rare entities.MRI is a most helpful diagnostic tool for this disorder.It should be stressed that early diagnosis and prompt surgical intervention are of great importance for prognosis of spontaneous spinal epidural hematoma.

Objective To investigate the clinical features, diagnosis and treatment of acute mesenteric isehe-mic disease. Methods Clinical data of 15 patients with acute mosenteric ischemic disease were analyzed retrospective-ly. Results Operation was performed on 14 patients and 1 patient received conservative treatment, 9 cases recovered and 5 died postoperatively. Conclusion Color ultrasound and selective angiography are effective examinations for early diagnosis of acute mesenterie ischemic disease. Early resection of necrotic bowel and application of anticoagulant post-operatively are effective to reduce the mortality. Conservative treatment is still effective for elective patient.

Total hip arthroplasty (THA) has developed rapidly in recent years, which reconstructs the joint function of some terminal hip joint diseases and obtains favorable efficacy. However, the stress load alters in the proximal femur following THA, leading to "adaptable bone reconstruction", which is characterized by thin cortical bone, decreased bone density, and bone loss surrounding prosthesis, in particular calcar femorale. This paper analyzed the effects of cement and cementless prosthesis, coated prosthesis, and THA approaches on stress shielding in the proximal femur to reduce stress shielding effect by improving prosthesis design, low elastic modulus materials, decreased section area of the prosthesis, cement prosthesis, appropriate coated materials and improved THA approaches.

Objective:To investigate the cause and preventive measures of chemotherapy-related death from human malignant neoplasms.Methods:A retrospective study was carried out to evaluate the clinical data of 15 patients with chemotherapy-related death of human neoplasms in 2008.The cause,treatment,survival time after chemotherapy and preventive measures were analyzed.Results:The average age of the 15 patients was 52.4 years,and 5 of them were treated with docetaxel.The mean survival time after chemotherapy was 16.8 days.5 cases presented severe sehematological toxicity, and 2,breath failure.Conclusion:Chemotherapy-related death from human malignant neoplasms was correlated with disease history,age and chemotherapeutic agents,etc.;therefore,no use of docetaxel for patients aged over 60 years or with hepatic and lung diseased history could decrease the chemotherapy-related death.
