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.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

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.

BACKGROUND:Currently,spinal cord injury imposes a huge psychological and economic burden on patients and the National Health Service.The prevention,treatment,and rehabilitation of spinal cord injury have become an important topic in the field of medicine.Therefore,it is important to explore new effective therapeutic strategies based on an in-depth understanding of the underlying molecular mechanisms of spinal cord injury.OBJECTIVE:To review the research progress on the mechanism of action of mesenchymal stem cell-derived exosomes loaded with various miRNAs in improving the function of spinal cord injury,and based on the current status of clinical translation,to put forward a few thoughts and outlooks on their clinical use.METHODS:The first author searched CNKI and PubMed databases using"mesenchymal stem cells,exosomes,spinal cord injury,miRNA,pathophysiology,clinical translation,clinical trials,good manufacturing practice"as Chinese and English search terms.The types of literature included treatises and reviews,and the language types were English and Chinese.Finally,72 papers were screened and analyzed.RESULTS AND CONCLUSION:(1)This article outlines the biological properties of exosomes and the advantages that they can serve as good vectors for loading miRNAs.A variety of miRNAs mediated by mesenchymal stem cell-derived exosomes mainly promote the recovery of neuronal function by regulating the expression of nerve regeneration-associated proteins,repressing RAS homologous gene family member A,activating cyclophosphoadenosine effector-binding proteins,and signaling and transcriptional activation proteins 3,and regulating phosphoinositide and tensin homologue/programmed cell death factor 4 pathways.Inflammatory responses were improved by regulating endoplasmic reticulum-to-nucleus signaling 1,expression of interferon regulatory factor 5,Toll-like receptor 4/nuclear factor-kappa B pathway,and down-regulating related pro-inflammatory factors.Angiogenesis was promoted by inhibition of germination-associated domain 1-containing EVH1 and phosphatidylinositol 3-kinase regulatory subunit 2.(2)Further comparative analyses revealed that miR-216-5p,miR-145-5p,and miR-146b improved inflammatory responses by regulating related pathways.Combining these miRNAs may produce more significant effects;hypoxic preconditioning may be a preconditioning method to increase the efficacy of exosomal therapy.(3)There are currently no clinical trials applying mesenchymal stem cell-derived exosomes to spinal cord injury,which is related to the need to meet good manufacturing practices before they can be put into clinical use.Challenges such as the need for large-scale,high-volume cell production,the lack of an efficient and uniform method for isolating exosomes,and the need to pass a strict regulatory approval mechanism prior to clinical use have impeded the clinical entry.(4)miRNAs have great potential as exosomal contents of mesenchymal stem cells in the treatment of spinal cord injury,and their mechanism of action should be explored in depth as well as accelerated to the clinical trial stage in order to provide a new and effective method for the treatment of spinal cord injury.

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.

[Purpose]To investigate the choice of medical institutions for the first-treatment of can-cer patients after diagnosis and the factors influencing it,so as to provide a reference basis for the rational allocation of health resources and the promotion of hierarchical diagnosis and treatment of cancer.[Methods]A total of 1 140 common cancer patients from 1 provincial,3 municipal and 6 county-level medical institutions in Shandong Province were included in the study,and a ques-tionnaire survey was conducted on their basic personal information and the selection of medical institutions.Chi-square test and Fisher exact test were used to compare different groups,and mul-ti-classification unordered Logistic regression were used to explore the factors influencing the se-lection of cancer patients.[Results]1 077 valid questionnaires were collected.The selection rates of first-treatment institutions for cancer patients were county hospitals(29.90％),city hospitals(35.28％),and provincial hospitals(34.82％),and the high level of medical care was the main reason for the selection of first-treatment institutions for cancer patients.The results of multi-clas-sification unordered Logistic regression showed that when choosing municipal and county medical institutions as the first treatment institution compared to choosing a county medical institution for the first treatment as a reference,compared to patients with stage Ⅰ tumors,patients with tumor stages at stage Ⅲ(OR=1.789,95％CI:1.014～3.158)and stage Ⅳ(OR=2.005,95％CI:1.179～3.409)were more likely to choose municipal medical institutions;and patients with annual house-hold income of 10 000～＜50 000 CNY(OR=0.625,95％CI:0.414～0.943)were less likely to choose mu-nicipal medical institutions compared to those with an annual household income of＜10 000 CNY.When choosing provincial and county medical institutions as the first treatment institution com-pared to patients in stage Ⅲ(OR=2.885,95％C1:1.549～5.372)and stage Ⅳ(OR=3.104,95％CI:1.724～5.586)compared to patients with stage Ⅰ tumors when choosing a county medical institu-tion for the first treatment was used as a reference;married(OR=2.248,95％CI:1.127～4.484)patients were more likely to choose provincial healthcare organizations than unmarried/divorced/widowed patients;patients with a family history of cancer compared to patients without a family history of cancer(OR=1.650,95％CI:1.115～2.441)were more inclined to choose provincial healthcare institutions;compared with patients＜45 years old,patients over 60 years old(OR=0.483,95％CI:0.242～0.962)were less inclined to choose provincial hospitals;and compared with patients who were not aware of knowledge related to cancer,those who were aware of knowledge related to cancer(OR=0.613,95％CI:0.441～0.852)patients were less inclined to choose provin-cial hospitals.[Conclusion]Vigorously carrying out publicity on cancer prevention and treatment knowledge,improving the cancer prevention and treatment literacy of cancer patients.strengthen-ing vertical cooperation among medical institutions at all levels,improving the provincial-munici-pal-county cancer prevention and treatment network,and promoting the sinking of high-quality medical resources are important ways to improve the cancer prevention and treatment capacity of counties and promote the work of hierarchical medical system.
