ABSTRACT

Objective:To develop the rehabilitation needs questionnaire for stroke patients, so as to provide a tool for medical staff to implement continuous rehabilitation services.Methods:Based on the conceptual framework of the International Classification of Function, Disability and Health, and on the basis of literature review and qualitative research, the questionnaire items were preliminatively established after two rounds of Delphi expert consultation, and 130 stroke patients admitted to the Department of Neurology and Rehabilitation of the First Hospital of Shanxi Medical University from April to December 2021 were selected to test the reliability and validity of the questionnaire. And 200 stroke patients were selected for confirmatory factor analysis to form a formal scale.Results:Exploratory factor analysis extracted a total of 4 common factors: physiological function rehabilitation needs, social rehabilitation environmental support needs, emotional/psychological support needs, rehabilitation knowledge/information needs. After project analysis and 3 exploratory factor analysis, a final questionnaire containing 16 items was formed.The Cronbach α of the questionnaire was 0.935, with a broken half reliability of 0.824. The fitting index of confirmatory factor analysis was within the standard range. The χ2/ df was 2.979, the incremental fitting index was 0.907, the comparative fitting index was 0.906, and the root mean square error of approximation was 0.100. Conclusions:The reliability and validity of the rehabilitation needs questionnaire for stroke patients are good, which can preliminarily assess the rehabilitation needs of stroke patients.

ABSTRACT

To improve collagen production by recombinant Pichia pastoris, we applied Placket-Burman and Box-Behnken design to optimize the fermentation medium. Through Placket-Burman design, three variables in the medium (concentration of yeast extract, peptone and glycerol) were selected for having significant effect on cell dry weight. Through Box-Behnken design regression coefficients analysis, a secondary degree polynomial equation was established, and the optimum levels of the three variables were yeast extract 1.13%, peptone 1.61% and glycerol 0.86%. During the growth period, an average cell dry weight of 4.41 g/L was obtained after 12 h fermentation, increased by 26%. Through high density fermentation, the production of recombinant human collagen (Ⅲ) was up to 4.71 g/L in 22 L fermentor. The recombinant human collagen (Ⅲ) exhibited good results to repair acetic acid induced gastric ulcer in rats.

ABSTRACT

PurposeTo investigate the mechanism of BM210955 (ibandronate, a new bisphosphonate drug manufactured in China)in the prevention of bone loss in vitro. MethodsThe osteoclasts isolated from the long bone of 10-day-old Rabbit were cultured on glass and bone slices in different concentration of BM210955. TRAP(tartrate resistant acid phosphonase) staining for osteoclast and TB( toluidine blue)staining for resorption lacunae were used on bone slices and Fluorescence (orange acridine) staining for apoptosis cell on glass slices was used;Multinucleated( three and more nuclei) TRAP positive cell and Apoptosis cell and Pits were counted. ResultsThe BM210955 decreased the multinucleated cell number by 73% in 10-8 mol/ L;The inhibitory rate of pit formed was correlate to concentration as 31.58%, 76.32% and 87.99% to 10-12, 10-10 and 10-8 mol/L; The apoptosis induction was shown in above 10-8 mol/L, and the apoptosis rate was 62% in 10-4 mol/L. Conclusions Induction of osteoclast apoptosis and decrease of the cell number and inhibition of resorptive ability were the major mechanism for bone loss prevention effect of BM210955 in vitro.
