Objective To explore the value of electroneurophysiological detection in diagnosis of children progressive muscular dystrophy (PMD).Methods The clinical features and laboratory data were analyzed in 32 children with PMD ,and electromyography(EMG) and nerve conduction velocity(NCV) were performed.Parameters studied included spontaneous activity , duration and amplitude of motor unit potential(MUP),pattern of recruitment as strong contracting,sensory conduction velocity(SCV),motor conduction velocity(MCV), distal latency and distal amplitude. Results The abnormality rates of spontaneous potentials was 49.2% and 80.9% in tibialis anterior.The decrease of duration of MUP was 29.7%-62.4%.Amplitude of strong contracting was significantly decreased.There were different from those in normal children(P

Objective To study the individualized dose of warfarin in treating atrial fibrillation in elderly patients. Methods Forty-one elderly in-patients with atrial fibrillation were recruited.Warfarin was used tO start anti-coagulation therapy with the target INR value 1.6-2.5.The data of demographic variables,concomitant diseases,medications and laboratory values were collected,then correlated these factors with the maintenance dose of warfarin. Results Warfarin dose requirements were significantly associated with age(r=-0.535,P＜0.01),sex(r=-0.494,P＜0.01),height (r=0.484,P＜0.01),weight(r=0.453,P＜0.01),body surface area(r=0.388,P＜0.05),concomitant use of a sulfonylurea medication(r=-0.446,P＜0.01)and serum albumin level(r=0.520,P＜0.01).The multivariate regression model includedthe variables of age,sex,serum albumin level and concomitant use of a sulfonylurea medication.This algorithm explained 65.4%of the variance in the maintenance dose of warfarin(R=0.808,R2=65.4%). Conclusions The warfarin dose in treating atrial fibrillation in elderly patients can be estimated from demographic,clinical and laboratory factors that can be obtained at the time of warfarin initiation.

Objective To investigate the hypoglycemic and antioxidation effects of the red alga Porphyridium cruentum in diabetic mice induced by alloxan. Methods The diabetic models were established by intravenous administration of alloxan 70 mg?kg~(-1).Then the diabetic mice randomly were divided into four groups, Among them ,two groups were given ig the algal biomass 600,1200mg?kg~(-1) ,respectively. After 18 days, the contents of blood glucose, plasma lipids and the activities of SOD were detected. Results Compared with the diabetic model, the algal biomass 600,1200mg?kg~(-1) could significantly decrease the blood glucose.A trend towards lower plasma triglyceride level was observed in test groups. In addition the activity of plasma SOD was significantly enhanced in high dose group. Conclusion Porphyridium cruentum could reduce the level of blood glucose and effectively enhance the ability of antioxidation in the diabetic mice induced by alloxan.

BACKGROUND: Human granulocyte-macrophage colony stimulating factor (hGM-CSF) is a kind of cytokine which can stimulate the differentiation and proliferation of haematopoictic precursor cells and plays an important role in the process of immunoloregulation. Escherichia coli (E.coli) expression system has advantages,such as low cost and high output, over other systems.Therefore, E.coli is still the most commonly used exogenous gene expression system.OBJECTIVE: To observe the expression of hGM-CSF in the E.coli swain DH5α.DESIGN, TIME AND SETTING: The present observational experiment was performed at the Central Laboratory of Biotechnology Research,China Three Gorges University between February and June 2007. MATERIALS: Plasmid pBR322hGM-CSF was purchased from American Type Culture Collection, USA.hGM-CSF antibody was sourced from Sigma Company, USA.IPTG, X-gal,and vector pMGT-18 were purchased from Shanghai Bioengineering Technology Company, China. METHODS: Primer was designed according to hGM-CSF gene. Taking cloning vector plasmid pBR322-hGM-CSF as template, hGM-CSF gene was acquired and recombined into prokaryotic expression vector pGEX-4T-1. Recombinant plasmid confirmed by enzyme digestion and sequencing was transformed into E.coli strain DH5α and induced by isopropy-β-D-thiogalactoside (IPTG). Expression product was identified by sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE) and detected by Western blotting assay. MAIN OUTCOME MEASURES: hGM-CSF expression in the E.coli strain DH5α. RESULTS: SDS-PAGE results revealed that the recombinant hGM-CSF protein with relative molecular weight of 40 500 was produced up to approximately 17.9% of total protein. Western blotting detection results indicated that there was a 40 500 bp brand. CONCLUSION: The present study reconstructed prokaryotic expression vector pGEX-hGM-CSF, induced its expression in the E.coli strain DH5α, and obtained hGM-CSF fusion protein.

Objective To illustrate and discuss the technique and clinical value of scapula Y-position radiography.Methods Scapula Y-position radiographies were performed on 110 patients with shoulder joint injury or omalgia.The patient standed in front of the panel face to face, with the affected joint closed to the panel, and the arms fell naturally and palms pronated to stick close to the body.The angle between the coronal plane and the panel was about 55 to 65 degree, put the affected caput humeri at the center of the panel,tilted the tube to foot-side by 15 degree,and aimed the axis at caput humeri.Results Among the 110 patients, 82 radiographies were successfully taken by the first time,28 failed because of the inappropriate body-tilt angle.We had exposed 5 acromion fractures cases, 20 flexural and hook-form acromion cases, 35 cases with the acomion-caput humeri distance less than 1 cm, and 2 coracoid fracture cases.Conclusion Scapula Y-position radiography has high clinical value that could expose the osseous anatomic exit of the rotator cuff and guide the clinical treatments.
