ObjectiveTo investigate the effects of rehabilitation therapy at early stage following spinal cord injury on the patients function recovery.Methods88 cases with spinal cord injury were divided into early rehabilitation group(n=50) and control group (n=38) according to the start time of the rehabilitation therapy (within 2 weeks or after 3 months).Rehabilitation assessment of the patients with Barthel index and Functional Independence Measure (FIM) was carried out before and 3 months after the rehabilitation therapy respectively.ResultsBarthel index and FIM score all improved after the rehabilitation therapy in two groups, but the improvements were more significant in early rehabilitation group(P<0.01).ConclusionEarly rehabilitation treatment improves the function of patients with spinal cord injuries.

Objective To explore the clinical application value of MRI fat quantification parameter[verte-bral bone marrow fat fraction(FF)]combined with 25-hydroxyvitamin D[25(OH)D]in predicting fracture risk in patients with osteoporosis.Methods A total of 90 patients with osteoporosis who were admitted to the hospital from January 2023 to April 2024 were selected as the subjects.Among them,50 patients with osteoporotic vertebral com-pression fractures were included in the fracture group,and 40 patients without fractures were included in the control group.All patients underwent the iterative decomposition of water and fat with echo asymmetry and least-squares estimation(IDEAL-IQ)method of MRI to measure the FF of each vertebra among L1-5 and the average FF of L1-5.Serum 25(OH)D level was detected by electrochemiluminescence method.FF and serum 25(OH)D levels of the two groups were compared.The correlation of FF,25(OH)D and bone mineral density(BMD)was analyzed.Multi-variate logistic regression analysis was conducted to screen the risk factors for fracture in patients with osteoporosis.Receiver operating characteristic(ROC)curves were used to evaluate the predictive value of FF,25(OH)D,and their combination for fracture in patients with osteoporosis.Results Patients in the fracture group were older than those in the control group.BMD and serum 25(OH)D level were lower than those of the control group(P<0.05).The FF of L2 and average FF of L1-5 in the fracture group were higher than those in the control group(P<0.05).Correlation analysis results showed that the FF of L2 and the average FF of L1-5 were negatively correlated with BMD(P<0.05),while serum 25(OH)D level was positively correlated with BMD(P<0.05).Multivariate logistic regression analysis showed that age and FF of L2 were independent risk factors for fracture in patients with osteoporo-sis,while BMD and 25(OH)D were protective factors(P<0.05).ROC curves indicated that the AUC values of FF of L2 and 25(OH)D for predicting fracture were 0.714(95%CI:0.606～0.822)and 0.774(95%CI:0.672～0.876).The AUC of joint prediction was 0.923(95%CI:0.867～0.978),which was significantly larger than that of separate prediction(P<0.05).Conclusions FF of L2 and serum 25(OH)D are related to fracture in patients with osteopo-rosis.Age and BMD are factors influencing the occurrence of fracture in patients with osteoporosis.FF of L2 and 25(OH)D have certain predictive value for fracture risk in patients with osteoporosis,and combined detection of the two can improve predictive efficiency.
