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.

Objective To introduce the causes of accidents and the diagnosis and treatment of two patients with radiation-induced skin injury admitted to our hospital in 2023, and to provide a reference for the clinical treatment of subsequent radiation-induced skin injury. Methods The clinical treatment process of two patients with acute skin injury caused by external radiation exposure were summarized and analyzed. Results The exposure history of the two patients was reconstructed, the flaw detection scenario was simulated, the biological dose and hand skin exposure dose were estimated, and the infrared thermal imaging device was used for dynamic monitoring. A comprehensive analysis was conducted based on clinical manifestations and other data. The diagnosis of “Xie” was excessive exposure combined with acute radiation-induced skin injury on both hands (Grade IV for the right hand palm, index finger, and middle finger and Grade II for the left hand little finger). The diagnosis of “Hao” was acute radiation-induced skin injury on both hands (Grade I). The two patients received different clinical treatment measures: “Xie” was treated with both local and systemic therapies, while “Hao” was mainly treated with systemic therapy. Conclusion After systematic and effective treatment, the radiation-induced skin injuries healed in both patients.

Aim To establish the pyroptosis model of rat chondrocytes induced by tumor necrosis factor α(TNF-α)in order to study the effect of lysine acetyl-transferase 7(KAT7)on pyroptosis of chondrocytes.Methods Chondrocytes of rat knee joint were isolated by type Ⅱ collagenase digestion,and were identified by toluidine blue staining and Col Ⅱ immunofluorescence.CCK-8 was used to evaluate cell viability.Western blot was used to detect the expression of pyroptosis-related proteins NLRP3,GSDMD,caspase-8 and KAT7 in cells intervened with TNF-α,adenovirus overexpression of KAT7(KAT7-oe)and KAT7 inhibitor WM-3835.The microstructure of the cells was observed by scanning e-lectron microscopy.Pyroptosis was detected by TUNEL staining,and the expression of pyroptosis-related pro-tein and KAT7 was detected by immunofluorescence.Results Compared with the empty virus group,KAT7-oe inhibited cell viability,promoted the expression of pyroptosis-related proteins,and TNF-α enhanced this effect.At the same time,the expression of KAT7 and pyroptosis-related proteins in the TNF-α stimulation group increased,and WM-3835 reduced the related proteins expression.Electron microscopy showed that KAT7-oe caused cell swelling,deformation,membrane perforation and rupture,while WM-3835 could restore cell morphology.TUNEL staining and immunofluores-cence results also confirmed that KAT7-oe induced chondrocyte pyroptosis,and WM-3835 could down-reg-ulate the fluorescence of pyroptosis-related proteins.Conclusions The expression of KAT7 increases in rat chondrocyte pyroptosis model,and the intervention of KAT7 expression affects signal molecules related to py-roptosis pathway,suggesting that KAT7 may be related to chondrocyte pyroptosis.

BACKGROUND:Cellular autophagy maintains metabolism and in vivo homeostasis through the autophagosome-lysosome degradation pathway,which is closely related to the impaired cell death and functional recovery of distal neurons after spinal cord injury,and targeting cellular autophagy to promote the functional recovery of the spinal cord after spinal cord injury is a promising therapeutic direction.OBJECTIVE:To summarize the role of cellular autophagy in spinal cord injury,related regulatory mechanisms of cellular autophagy and therapeutic strategies.METHODS:PubMed and CNKI databases were searched with the search terms of"spinal cord injury,autophagy,regulatory mechanisms,autophagy pathway,therapeutic target"in English and Chinese,respectively.A total of 133 English and 4 Chinese articles were included for review.RESULTS AND CONCLUSION:(1)Autophagy,a form of programmed cell death,has been shown to play a crucial role in the progression and treatment of spinal cord injury.Most studies have shown that moderate activation or promotion of autophagy promotes neurological recovery by decreasing inflammatory responses and apoptosis.A few studies have reported that excessive activation of autophagy,on the contrary,impedes neurological recovery following spinal cord injury.(2)After spinal cord injury,PI3K/AKT/mTOR,MAPK,AMPK and p53 signaling pathways,and factors such as Beclin-1,ATG and LC3 regulate the initiation and development of cell autophagy in a positive or negative manner.(3)Promoting or inhibiting autophagy may be a promising therapeutic strategy to modulate the pathogenesis of traumatic spinal cord injury.And the drugs amlodipine,metformin,and minocycline,the Chinese medicines hawthorn leaf total flavonoids,betulinic acid,oxidized ginseng saponins,acupuncture,and extracellular vesicles of different cellular origins,exosomes and reactive oxygen species-responsive composite fibers as activators of cellular autophagy attenuate secondary injury in response to spinal cord injury by activating cellular autophagy,while the drugs insulin-like growth factor 1 and eladavone,Chinese medicine ginseng saponin,acupuncture,and hydrogel carrying basic fibroblast growth factor as inhibitors of cellular autophagy promote functional recovery after spinal cord injury by inhibiting excessive cellular autophagy.(4)The related regulators of cellular autophagy are interconnected,and the bi-directional effects of cellular autophagy on spinal cord injury make it necessary to further explore the dominant factors that regulate cellular autophagy.(5)Research on the use of autophagy as a therapeutic target for spinal cord injury is mostly carried out in animal models,but there are no autophagy-related drugs used in the clinical practice,and their safety and efficacy need to be further investigated in the clinical field.

Objective This study examined the association between smoking and cognitive decline through a cohort in rural population in Xi'an.Methods Data were collected from the cognitive impairment cohort of middle-aged and elderly people in rural areas of Xi'an.The cohort selected the population aged 40 years and above in rural Xi'an.The baseline survey was completed between October 2014 and March 2015,and two follow-up visits were conducted in 2016 and 2018.This study took the baseline cognitively normal population of this cohort as the research subjects.According to the survey results in 2018,the population was divided into three groups according to smoking status:smoking,quitting and non-smoking.Cognitive function was assessed by Mini-Mental State Examination(MMSE).△MMSE(2014 rating-2018 rating)≥2 was defined as cognitive decline,and △MMSE＜2 was defined as cognitive stability.Binary Logistic regression model and stratified analysis were used to analyze the relationship between smoking and cognitive decline and the influence of age on the relationship.Results A total of 1 289 subjects were included in this study.According to smoking status in 2018,they were divided into non-smokers(910,70.6％),smokers(335,26.0％),and ex-smokers(44,3.4％).In the total population,there was no significant difference in the incidence of cognitive decline among non-smokers,smokers and ex-smokers(17.3％vs.16.1％vs.15.9％,P=0.880).When stratified by age,there was no significant difference in the incidence of cognitive decline among the three groups in the subgroup of age＜65 years(16.5％vs.13.2％vs.12.1％,P=0.365).In the subgroup of age≥65 years,no significant difference was found in the incidence of cognitive decline among non-smokers,smokers and ex-smokers(20.8％vs.30.9％vs.27.3％,P=0.306).After adjusting for confounding factors,smokers had a significantly higher risk of cognitive decline than non-smokers(OR=14.139;95％CI:1.541-129.705;P=0.019).There was a trend of cognitive decline in the ex-smokers group,but with no statistical significance(OR=8.252;95％CI:0.630-108.175;P=0.108).Conclusion Smoking is positively associated with cognitive decline in the elderly,suggesting that smoking may accelerate cognitive decline in this population.

Objective:To investigate the promoting effect of individualized instruction combined with a blended learning model (IIBLM) in continuing training of neurology.Methods:A total of 93 trainees who received continuing training in Department of Neurology, The First Affiliated Hospital of Sun Yat-sen University, from August 2022 to December 2024 were enrolled as subjects. The 50 trainees registered since January 2024 were enrolled as observation group and received IIBLM teaching, including sub-specialty modular training, a cycle-adaptive cultivation system, a "mutual-selection" mentorship program, an on/off-line dual-track curriculum system, a dynamic course allocation mechanism based on "mutual selection", and a competency growth evaluation system, while the 43 trainees registered before January 2024 were enrolled as control group and received traditional teaching. A questionnaire survey and comprehensive competency assessments were performed to evaluate the effect of teaching, and the t-test, the chi-square test, and the qualitative analysis were used for statistical analysis. Results:Compared with the control group, the experimental group showed systematic improvements in clinical contents, theoretical curriculum, faculty competency, and workflow arrangement during continuing training, with a significant difference in the score of workflow arrangement between the two groups [(9.58±0.67) vs. (9.07±1.44), t=-2.13, P=0.037]. The observation group had a score of (97.70±1.30) for dynamic course allocation, an overall satisfaction rate of 97.15%, and a course benefit rate of 97.55%. The qualitative analysis showed that the trainees in the control group mainly complained of course monotony, while those in the observation group expected to enhance interdisciplinary integration and the cultivation of scientific research abilities. In addition, the results of competency assessment showed a continuous improvement in teaching effect after reform, with no significant difference. Conclusions:IIBLM teaching effectively enhances professional qualities, clinical competency, and the degree of satisfaction with courses among the trainees receiving continuing training, and it also revealed the necessity of interdisciplinary collaborative teaching and the integration of research and clinical practice.

Objective:To investigate the influences of asiaticoside(AS)on inflammatory response and oxidative stress in rats with mesangial proliferative glomerulonephritis(MsPGN)by regulating the rat sarcoma(Ras)/extracellular signal regulated kinase(ERK)/mitogen activated protein kinase(MAPK)signaling pathway.Methods:Sixty SPF SD rats were randomly divided into sham operation group(Sham group),MsPGN model group(Model group),low-dose AS group(AS-L group,40 mg/kg),high-dose AS group(AS-H group,80 mg/kg),high-dose AS+Ras/ERK/MAPK signaling pathway activator group(AS-H+anisomycin group,80 mg/kg AS+10 mg/kg anisomycin),with 12 rats in each group.Rat model of MsPGN was established by modified serum immunization.The 24 h urine protein content of rats in each group was detected by Coomassie brilliant blue method.HE staining and PSA staining were used to observe the pathological changes of renal tissue of rats in each group.TUNEL staining was used to detect apoptosis of rat glomerular cells in each group.Levels of serum creatinine(Scr),superoxide dismutase(SOD),blood urea nitrogen(BUN),malondialdehyde(MDA),and levels of IL-18,IL-1β,TNF-α,SOD and MDA in renal tissues were measured by ELISA.Protein levels of Ras,p-ERK1/2,ERK1/2,MAPK and p-MAPK in renal tissues of rats in each group were detected by Western blot.Results:①AS alleviated inflammatory reaction and oxidative stress injury in MsPGN rats.Compared with Sham group,24 h urine protein content,glomerular cell apoptosis rate,serum Scr,BUN,MDA levels,renal tissue IL-18,IL-1β,TNF-α,MDA levels in model group were significantly increased(P<0.05),while SOD level in serum and renal tissue was significantly decreased(P<0.05).HE staining showed that the glomerulus of rats had severe mesangial hyperplasia,a large amount of matrix deposition,and the basement membrane was significantly thickened.Compared with model group,24 h urine protein content,glomerular cell apoptosis rate,serum Scr,BUN,MDA levels,renal tissue IL-18,IL-1β,TNF-α,MDA levels in AS-H group rats were significantly decreased(P<0.05),while SOD level in serum and renal tissue was significantly increased(P<0.05),HE staining showed alleviated mesangial hyperplasia injury.②AS downregulated the Ras/ERK/MAPK signaling pathway.Compared with Sham group,expression of Ras protein and phosphorylation level of ERK1/2 and MAPK in Model group were significantly increased(P<0.05);compared with Model group,expression of Ras protein,phosphory-lation level of ERK1/2 and MAPK in AS-H group were significantly decreased(P<0.05),and anisomycin reduced the inhibitory effect of AS on inflammatory response and oxidative stress injury in MsPGN rats(P<0.05).Conclusion:AS may reduce the inflammatory re-action and oxidative stress injury in MsPGN rats by down-regulating Ras/ERK/MAPK signaling pathway.

The advancement of surgical techniques enables effective treatment for many patients with oral and maxillofacial tumors.How-ever,post-surgery problems such as chewing,swallowing and speech difficulty may arise due to the defects in speech organs and inade-quate compensatory function of tissue flap repair.Speech disorders,in particular,isolate patients by making it difficult for them to com-municate with others,not only impact their quality of life but also potentially lead to psychological problems and social interaction disor-ders.Although the decline in life quality and other related issues caused by speech dysfunction due to surgery and radiotherapy or chemo-therapy have been widely recognized,there is currently no standardized and universally applicable assessment method and standardized re-habilitation treatment management guideline or consensus for speech disorders following oral and maxillofacial tumor surgery at home and abroad.Based on previous clinical practice,combined with the characteristics of speech disorders in patients after oral and maxillofacial tumor surgery,the clinical experience of the experts in maxillofacial tumor surgery and rehabilitation and the relevant domestic and foreign literature,relevant experts organized discussions and modifications,reach a consensus on core content such as the assessment of speech disorders and the implementation plan for early rehabilitation treatment management,providing a reference for clinical practice,in order to improve patients'speech-related life quality and enhance the assessment and rehabilitation treatment techniques for speech disorders after oral and maxillofacial tumor surgery.

Objective To develop a risk management system for complications associated with peripheral venous indwelling needles and to evaluate its application effect in order to reduce the risk of related complications.Methods We designed a comprehensive risk management system for peripheral intravenous indwelling needle complications,integrating specialized evidence-based guidelines with clinical practice insights,including 5 modules:intelligent assessment and decision support,intelligent inspection reminders,educational modules,collaborative case management procedures,and a knowledge base.Patients admitted to the neurology and internal classification metabolism departments of a tertiary hospital in Jilin Province were conveniently selected as the research subjects.Patients were assigned to a control group(from May to July 2022,before the implementation of the system)and an experimental group(from September to December 2022,after the implementation of the system).The incidence of complications,duration of indwelling needle,compliance rate of core indicators for nursing quality and number of nursing consultations were compared between the groups.Additionally,a self-administered questionnaire was used to assess clinical nurses'evaluations of the system.Results A total of 189 patients were included in the experimental group and 177 patients in the control group.The incidence of complications associated with peripheral intravenous indwelling needles was lower than that in the control group.The duration of indwelling peripheral intravenous needles was longer than that in the control group.The quality compliance rate of peripheral venous indwelling needle care in the experimental group was higher than that in the control group,and the number of consultation cases in the experimental group was higher than that in the control group.Comparisons between the 2 groups showed statistically significant differences for all indicators(P＜0.05).The nurses'recognition rates for the system's user-friendliness,professional guidance,and patient benefit were 77.78％,81.74％,and 82.13％,respectively.Conclusion The application of a peripheral vein indwelling needle complication risk management system can reduce the incidence of complications,prolong the duration of indwelling,and improve nursing quality.Nurses have a high recognition of this system.

Recent studies have shown that the physiological homeostasis of oral mucosal cells is regulated by the circadian clock.Dis-ruption or dysfunction of the circadian clock is closely associated with the development of oral squamous cell carcinoma(OSCC).Research based on the circadian clock offers a novel perspective on the pathogenesis and therapeutic strategies for OSCC.However,there is current-ly limited research on this topic,and people generally have insufficient understanding and recognition of the circadian clock.Given the complexity and challenges of circadian clock which is the fourth dimension of medical research,we organize relevant experts based on summarizing the current research results of circadian clock in the pathogenesis and precision diagnosis and treatment of OSCC,combining the scientific principles of the circadian clock's role and their long-term research experience,then summarizes and recommends the con-sensus opinions for the research of circadian clock in the pathogenesis mechanism and precision diagnosis and treatment of human OSCC,with the hope of providing guidance for the basic research and clinical application of circadian clock or circadian rhythm in the pathogene-sis mechanism and precision diagnosis and treatment of oral and maxillofacial squamous cell carcinoma.
