As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

In hypoxic-ischemic brain damage (HIBD), the programmed cell death known as ferroptosis is significantly activated. Microglial cells demonstrate a high level of sensitivity to iron accumulation. Understanding how to regulate the dual role of microglia and transforming the microglial ferroptosis to a moderate and controllable process has considerable implications for the targeted treatment in HIBD. This paper serves as an overview of microglia-mediated ferroptosis in HIBD as a disease model. We discuss various aspects centered around microglia, including pathophysiological mechanisms, polarization and functions of microglia, molecular mechanisms of ferroptosis, signaling pathways, and therapeutic strategies. The review aims to provide a reference for studies of ferroptosis in microglia.

Objective To investigate the association of lipid accumulation product (LAP) and visceral fat index (VAI) with nonalcoholic fatty liver disease (NAFLD) and the value of LAP and VAI in predicting the risk of NAFLD. Methods A total of 708 subjects who underwent physical examination in China-Japan Friendship Hospital from September 2018 to May 2019 were enrolled and divided into NAFLD group ( n =426) and non-NAFLD group ( n =282), and the two groups were compared in terms of LAP, VAI, and related biochemical parameters. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups.The chi-square test was used for comparison of categorical data between groups. The Spearman test was used for correlation analysis. The subjects were divided into L1-L4 groups based on LAP and V1-V4 groups based on VAI, and the distribution of NAFLD was compared between groups; a logistic regression analysis was used to calculate the risk of NAFLD at different levels of LAP and VAI, and the receiver operating characteristic (ROC) curves were plotted for LAP, VAI, waist circumference (WC), and body mass index (BMI) in predicting NAFLD in different sex and body weight subgroups, so as to evaluate the value of each index in the prediction and diagnosis of NAFLD. Results Compared with the non-NAFLD group, the NAFLD group had significantly higher age, proportion of male subjects, proportion of subjects with a smoking history, and levels of LAP, VAI, WC, BMI, systolic blood pressure, diastolic blood pressure, alanine aminotransferase, aspartate aminotransferase, total cholesterol, triglyceride, low-density lipoprotein cholesterol, fasting blood glucose, and serum uric acid, as well as a significantly lower level of high-density lipoprotein cholesterol (all P < 0.01). NAFLD was positively correlated with the levels of LAP and VAI (Cramer's V=0.552 and 0.464). The multivariate logistic regression analysis showed that after adjustment for related risk factors, the risk of NAFLD in the L4 group was still 8.811 (95% confidence interval [ CI ]: 4.335-17.910) times that in the L1 group ( P < 0.001), and the risk of NAFLD in the V4 group was still 5.967 (95% CI : 3.263-10.912) times than that in the V1 group ( P < 0.001). The ROC curve analysis showed that both LAP and VAI had an area under the ROC curve (AUC) of > 0.7 in predicting the onset of NAFLD in different sex and body weight subgroups; the AUCs of LAP and VAI in the female subgroup were significantly higher than those in the male subgroup (LAP: 0.886 vs 0.785, P < 0.05; VAI: 0.824 vs 0.748, P < 0.05), and the corresponding sensitivities and specificities of LAP and VAI in the female subgroup were also higher than those in the male subgroup (sensitivity: LAP: 79.8% vs 63.7%; VAI: 77.9% vs 77.0%; specificity: LAP: 85.0% vs 81.1%; VAI: 77.6% vs 62.3%). Conclusion The risk of NAFLD increases with the increase in the levels of LAP and VAI. Both LAP and VAI have a good value in predicting NAFLD in different sex and body weight subgroups, especially in predicting NAFLD in the female population.

Objective To evaluate the characteristics of abdominal aorta wall motion in different stages of rats atherosclerosis with velocity vector imaging (VVI) technique. Methods Twenty-four healthy SD rats were on high-fat feeding after one week ordinary diet. Abdominal aortic intima-media thickness (IMT), end-systolic blood vessel diameter (Ds), peak systolic velocity (Vs), resistance index (RI), pulsatility index (PI) were measured before and at the end of 8th and 12nd week. Artery wall peak velocity (V_(max)), maximum tangential strain (S_(max)) and the maximum tangential strain rate (SR_(max)) were caculated with VVI. Results Abdominal aortic intima was rough and a small amount of foam cells were found under the light microscope at the end of 8 weeks of high-fat feeding. The values of Smax and SRmax measured at the end of 8th week of high-fat feeding decreased significantly than those of before high-fat feeding (P<0.05). At the end of 12nd week, abdominal aortic intimal was thicker and atherosclerotic plaque appeared somewhere. There were significant differences in artery IMT, Ds, Vs, RI, PI between before and the end of 2nd week of high-fat feeding (P<0.05);the values of V_(max), S_(max), SR_(max) decreased significantly than those of before and at the end of 8th week of high-fat feeding (P<0.05). Conclusion VVI can quantitatively evaluate the vessel wall elasticity in different stage of arteriosclerosis rats.
