Objective To explore the relationship between traditional Chinese medicine(TCM)constitution,functional connectivity(FC)of the dorsolateral prefrontal cortex(DLPFC),and fluid intelligence in university students to elucidate the mind-body relationship from a modern perspective of TCM.Methods From October 2023 to December 2023,a total of 96 college students of Jiangxi University of Chinese Medicine were included,and Classification and Identification of Constitution in Traditional Chinese Medicine:ZYYXH/T 157-2009,Raven's Advanced Progressive Matrices(RAPM)and resting-state functional near-infrared spectroscopy were used to evaluate TCM constitution,fluid intelligence,and FC of DLPFC.The differences in fluid intelligence between individuals with biased and balanced constitutions were compared using t-tests,and the associations among the TCM Constitution,RAPM score,and the FC between the left and right DLPFC were explored using partial correlation analysis.Results The tendency toward blood-stasis type and a dampness-heat type were positively correlated with the RAPM scores.College students with a tendency toward blood-stasis type exhibited significantly higher RAPM scores than those with a balanced constitution(P＜0.05).Additionally,significant negative correlations were observed between the tendencies toward blood-stasis and yin-deficiency types and the FC of the bilateral DLPFC.In contrast,a significant positive correlation was observed in individuals with balanced constitution tendencies.Conclusion The tendency toward blood-stasis type is associated with fluid intelligence levels and DLPFC functional activity in college students.This finding suggests that students with higher intelligence levels are more likely to exhibit blood-stasis type,highlighting the need for appropriate adjustments and interventions.

Objective To analyze the role of the key items list in the quality control of running medical records by com-paring the improvements of the quality of medical records,and to explore more effective ways of quality management of medical records.Methods Based on the goal setting theory and influencing factors of goal incentive utility,a list of key items for medi-cal record quality management was formulated,which was implemented in a children's hospital in Tianjin since April 2023.A to-tal of 4 823 operating medical records were collected from June 2022 to September 2023,and the defect rates of quality control items were compared by using statistical methods.Results After the implementation of the key items list,the average score of operating medical records was improved,and the defect rate decreased from 13.63％to 7.94％.Moreover,the defect rates of admission records,first-trip records,senior physician rounds records,consultation records,and surgical records decreased from 4.25％,3.07％,8.26％,and 10.56％to 1.61％,1.56％,4.41％,and 5.06％.Conclusion The implementation of key i-tems list management can effectively improve the quality of running medical records,reduce the defects of medical records,and improve the effects of medical record management.

Objective To compare the effectiveness of nano-hydroxyapatite/collagen (nHAC)and autologous mesenchymal stem cells (AMSCs) for the repair of femoral defect in a rabbit model with femoral defect under the monitoring of the synchrotron radiation hard X-ray. Methods The rabbit models of traumatic bone defect were established and completely randomized into three groups. The femoral defects filled with nothing were used as control group (Group A) , the femoral defects filled with nHAC as Group B and the femoral defects filled with nHAC + AMSCs as Group C. Phase-contrast imaging with synchrotron radiation hard X-ray was applied to detect the degradation and repair process of each group at postoperative weeks 4, 8 and 12, respectively. Results Phase-contrast imaging with synchrotron radiation hard X-ray could display the reparative process. Four weeks after operation, there was collapse in some defect areas in Group A, and the degradation of nHAC and new bone formation were observed in Groups B and C. Eight weeks after operation, fibrous tissues were observed in the defect area in Group A, while osteogenesis and nHAC degradation were more obvious in Groups B and C. Twelve weeks after operation, the defect areas were still unhealed and were substituted by fibrous tissues in Group A, tissue densities of defect areas in Group C were identical with periphery areas, and trabecular bones were formed in Group C. There were statistical differences in the osteogenesis between Group A and Groups B and C,with Group C the best. Conclusion Phase-contrast imaging with synchrotron X-ray can detect the reparative process at a micro-level and plays an important role in the development of tissue engineering.
