1.Spontaneous spinal epidural hematom aand spontaneous spinal subdural hematoma:report of six cases
Chinese Journal of Orthopaedics 2000;0(11):-
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 explore the efficacy and complications of surgical treatment for secondary hydrocephalus of cryptococcal menigitis. Methods The clinical data of 26 patients with secondary hydrocephalus of cryptococcal meningitis who underwent ventricular drainage (11 cases) and ventriculoperitoneal shunting (15 cases) procedures in our department from 1980 to 2002 were retrospectively reviewed. Results Both operation approaches had good effect on the secondary hydrocephalus, but ventriculoperitoneal shunting procedure was safer and more persistent. Conclusion Shunting procedure is a safe and effective therapy for hydrocephalus in patients with cryptococcal meningitis.

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.

Objective To investigate relationship between utrophin and dystrophin in muscle of patients suffered from several neurological muscular diseases.Methods Muscle biopsies of 26 cases of patients suffered from 8 categories neurological muscular diseases and 2 cases of control were analysed for utrophin and dystrophin by immunofluorescence experiments.Results In a majority of Duchenne muscular dystrophy (DMD) patients,their sarcolemma revealed absent,weak or discontinuous fluorescence for dystrophin.In non-DMD muscular dystrophies,lipid storage myopathy,myotonic dystrophy,inflammatory myopathies, neurogenic amyotrophy, polymyositis, mitochondrial encephalomyopathy, myogenic amyotrophy,immunofluorescence reactivity for dystrophin were strongly exhibited in entire sarcolemma.In normal biopsy sample,strong immunofluorescence reactivity for dystrophin was identified in entire sarcolemma,while weak and discontinuous fluorescence was identified on a minority of sarcolemma of DMD patients with severely reduced dystrophin.There was no immunofluorescence reactivity for utrophin in sarcolemma of DMD patients with moderate decreased dystrophin,non-DMD muscular dystrophies and other 6 categories of neurological muscular diseases,nor in sarcolemma of normal biopsies.Conclusions utrophin is expressed in sarcolemma of DMD patients,who have severely reduced dystrophin simultaneously. utrophin is absent in sarcolemma of other categories of neurological muscular diseases including non-DMD muscular dystrophies with normal dystrophin expression and DMD patients with moderately decreased dystrophin.

Objective To develop the Chinese version of the 35-item Medical Outcomes Study HIV Health Survey (MOS-HIV) and to assess the reliability and validity of MOS-HIV among HIV-infected individuals.Methods Between April and July of 2007,a croas-sectional survey of 758 HIV-infected individuals was conducted.Responses to the MOS- HIV were analyzed for its reliability and validity.Results Pearson's correlation coefficients of items for test-retest relia- bility ranged from 0.46-0.92,all internal consistency reliability coefficients exceeded 0.69,and all items were more strongly correlated with hypothesized scale than any other scale.Eight scales of MOS-HIV were significantly associated with CD_4 cell counts.Conclusions The Chinese version of MOS-HIV offers good reliability and validity and can be used as a tool to assess the quality of life of HIV infected individuals in China,thus providing evidence for further studying AIDS related quality of life in this country.
