OBJECTIVE: To evaluate the risk of ischemic stroke endpoints by establishing risk assessment models that combine Traditional Chinese medicine(TCM)and modern medicine ***/DESIGN: The proposed study is a registry-based participant survey conducted in seven hospitals nationwide in China. After obtaining informed consent, 3000 patients diagnosed with ischemic stroke will be recruited. One-year follow-ups will be performed on-site in hospitals and by telephone to track endpoint events. Comparative analysis of the prevalence of endpoint events and other TCM or modern medicine features in different groups will be conducted using frequency analysis and χ2tests, and the results will be expressed as composition ratios. Comparative analysis of quantitative scores and related patterns or symptoms will be conducted using a rank-sum test. Correlation analysis of endpoint events and TCM or modern medicine factors will be performed using a multivariate Cox proportional hazard ***: Previous reports have described modern medicine indicator-based risk assessment models for ischemic stroke endpoint events, but no such studies have included TCM features. Our new risk assessment model combines TCM and modern medicine indicators and thus has the potential to facilitate early warning, early intervention, and early control of ischemic stroke endpoint events.

Understanding the occurrence, development, and treatment of liver diseases is the main goal of hepatopathology research. Liver diseases are not only diverse but also highly heterogeneous among individuals. At present, research on liver diseases is conducted mainly through cell culture, animal models, pathological specimens, etc. However, these methods cannot fully reveal the pathogenic mechanism and therapeutic characteristics of individualized liver *** advances in three-dimensional cell culture technology(organoid culture techniques) include pluripotent stem cells and adult stem cells that are cultured in vitro to form self-organizing properties, making it possible to achieve individualized liver disease research. This review provides a comprehensive overview of the development of liver organoids, the existing and potential applications of liver regenerative medicine, the pathogenesis of liver disease heterogeneity, and drug screening.

Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal *** we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord *** report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal *** Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder ***,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord *** findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.

Objective To identify the characteristics of Chinese obesogenic environments at a provincial level, infer a spatial distribution map of obesity prevalence in 31 provinces, and provide a foundation for development of policy to reduce obesity in children and adolescents. Methods After scanning obesity data on subjects aged 7-17 years from 12 provinces in the China Health and Nutrition Survey 2011 and environmental data on 31 provinces from the China Statistical Yearbook 2011 and other sources, we selected 12 predictors. We used the 12 surveyed provinces as a training sample to fit an analytical model with partial least squares regression and prioritized the 12 predictors using variable importance in projection. We also fitted a predictive model with Bayesian analysis. Results We identified characteristics of obesogenic environments. We fitted the predictive model with a deviance information criterion of 61.96 and with statistically significant（P 〈 0.05） parameter estimates of intercept [95% confidence interval（CI）： 329.10, 963.11], log（oil）（CI： 13.11, 20.30）, log（GDP）（CI： 3.05, 6.93）, log（media）（CI：-234.95,-89.61）, and log（washing-machine）（CI： 0.92, 5.07）. The total inferred average obesity prevalence among those aged 7-17 was 9.69% in 31 Chinese provinces in 2011. We also found obvious clustering in occurrences of obesity in northern and eastern provinces in the predicted map. Conclusion Given complexity of obesity in children and adolescents, concerted efforts are needed to reduce consumption of edible oils, increase consumption of vegetables, and strengthen nutrition, health, and physical activity education in Chinese schools. The northern and eastern regions are the key areas requiring intervention.
