BACKGROUND:The new technique of spinal nonfusion is used for intervention of early spinal diseases. It can protect the spine motion function and treat the patients either. The interspinous U titanium alloy belongs to the new technique of spinal nonfusion. And this investigation will be a hot spot in the spinal nonfusion technique. OBJECTIVE:To explore the clinical mechanical property of spinal nonfusion interspinous U titanium alloy. DESIGN,TIME AND SETTING:Comparative observation. All patients were selected from the Department of Orthopaedics of Changhai Hospital between June 2006 and December 2007. PARTICIPANTS:A total of 28 patients with degenerative intervertebral disk protrusion and dynamic spinal stenosis,including 23 male and 5 female aged 41 to 58 years old. METHODS:All patients were randomly divided into two groups:intervertebral disectomy alone (n=20):affected segments were removed; implantation group (n=8):affected segments were removed and interspinous U titanium alloy was implanted following interspinous ligament. MAIN OUTCOME MEASURES:The height of the intervertebral space and vertebral canal area of the affected segment as well as JOA scores for lumbar vertebra postoperatively and during follow-up. RESULTS:All 28 patients were included in the final analysis. The height of the intervertebral space and vertebral canal area of the affected segment in implantation group were significantly increased compared with intervertebral disectomy alone group (P

Objective To explore the correlation between serum uric acid levels and uric acid excretion indexes in children with primary nephrot?ic syndrome(PNS),and to reveal the prevalence of hyperuricemia and its possible causes in PNS. Methods The clinical data in 74 cases of pe?diatric PNS were retrospectively analyzed. These patients were grouped as hyperuric acid(HUA)or non?hyperuric acid(NUA),and their clinical features and laboratory findings were compared between two groups,including age,serum uric acid,serum creatinine,urea,cystatin C,triglycer?ide,cholesterol,albumin,creatinine clearance rate,24 hours urine uric acid,serum uric acid/serum creatinine,uric acid clearance,and the frac?tional excretion of uric acid and other indicators of differences. In addition ,a correlation analysis was carried out for the excretion of uric acid index. Results Several factors were lower in HUA group than that of NUA group ,such as the serum albumin and fractional excretion of uric acid(P1=0.034,P2=0.025);while the serum cystatin C and serum uric acid/serum creatinine ratio(P1=0.038,P2=0.001)was higher in HUA group. The uric acid excretion was negatively correlated with serum uric acid levels in all 74 children with PNS(r=-0.43,P=0.016),and the serum uric acid/creatinine ratio was positively correlated with serum uric acid(r=0.486,P=0.001). Conclusion Both the increase of blood uric acid production and excretion reduction were observed in children with PNS ,and the serum uric acid levels and renal tubular function is closely related.

ObjectiveTo explore the risk factors related to senile dementia to develop intervention method.MethodsA combination of qualitative and quantitative methods was used to analyze the factors and their degree related to the incidence of dementia for the elderly.ResultsAgeing was the deterministic factor to senile dementia, and vascular factor was common risk for Alzheimer's disease (AD) and vascular dementia (VD).ConclusionActive intervention in early life, concern about women's groups especially in the mental health, and detemination of value range of the risk factors are needed.

Objective To investigate the clinical characteristics of childhood anaphylactoid purpura.Methods Seven hundred and sixty children with anaphylactoid purpura were included in this retrospective study.The clinicopathological features of childhood anaphylactoid purpura were analyzed,including age at onset,gender,season at onset,clinical and pathological manifestations,and complications such as purpura nephritis.Results Childhood anaphylactoid purpura commonly affected preschool and school-age children,and usually occurred in winter or spring.Of these patients,265 (34.87％) had gastrointestinal symptoms,298 (39.21％) had joint involvement,and 223 (29.34％) had renal impairment.Purpura nephritis mainly manifested as haematuria,proteinuria and nephritic syndrome,and was diagnosed in 91.91％ (91) of the patients receiving renal biopsy.The pathological grade of purpura nephritis varied from Ⅱ to Ⅲ in these patients.The distribution pattern of purpura was associated with complications.Conclusions Anaphylactoid purpura has age and season predilection.Purpura in both lower and upper extremities is likely to be complicated by gastrointestinal haemorrhage and joint involvement,and lower extremity purpura is more frequently to be complicated by nephritis than purpura in both lower and upper extremities.In general,childhood anaphylactoid purpura is a mild condition with a good prognosis.

Objective To investigate and assess the current situations on information management of rehabilitation service in Shanghai. Methods The information management in 6 districts in Shanghai were assessed in field, the fulfilling of the first- and second-degree index and the standard-reaching rate of the third-degree index were calculated separately according to the first-degree index- information management of the Evaluation Index System of Rehabilitation Service for All Disabled in Shanghai. Results The average fulfilling degree of the first-degree index was 73.1%. There were only 2 districts reached the standard of Registration of Rehabilitation. The average fulfilling degrees of the Development and Dynamic Maintenance of Rehabilitation Service Information Database were 50.0% and 66.7%, respectively. The standard-reaching rate of the Disabled Children First-diagnose Report System, Effectual Providing Referral Rehabilitation Service Across-the-board, Suspicious Disabled Persons Report System in Community were 16.7%, 16.7% and 50%, respectively. Conclusion The development and supervision of rehabilitation service information should be reinforced and the referral rehabilitation service should be improved.

Objective To investigate and assess the current situations of propagandizing and inculcating rehabilitation information in Shanghai. Methods The propagandizing and inculcating rehabilitation information in 6 districts in Shanghai were assessed in field, the fulfilling of the first- and second-degree index and the standard-reaching rate of the third-degree index were calculated separately according to the first-degree index- propagandizing and inculcating rehabilitation information of the Evaluation Index System of Rehabilitation Service for All Disabled in Shanghai.Results The average fulfilling degree of the first-degree index was 82.3%. There was 1 district reached the standard of Propagandizing Rehabilitation Information by Broadcast, Television, Newspaper, Magazine and Internet; the average fulfilling degrees of the Community Rehabilitation Function for the Disabled and the Community School Propagandizes and Inculcates the Rehabilitation Information for the Disabled are 66.7% and 33.3%, respectively. Conclusion The support from the government could make propagandizing and inculcating rehabilitation information carry out more successfully; utilizing the media adequately is important; propagandizing and inculcating rehabilitation information must be strengthened in community.
