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.

ObjectiveThis paper aims to investigate the efficacy and related actions of Guizhi Fulingwan in intervening in the mice with colitis-associated colon cancer （CAC） based on the immunosuppressive microenvironment associated with myeloid-derived suppressor cells （MDSCs）. MethodsSixty male C57BL/6 mice were randomly assigned to a blank group， a model group， an aspirin group （0.04 g·kg^-1）， and low-， medium-， and high-dose Guizhi Fulingwan groups （4.87， 9.75， and 19.50 g·kg^-1）， with ten mice per group. The CAC mouse model was established via combined induction of azoxymethane （AOM）/dextran sulphate sodium （DSS）. Drug intervention commenced in week five， with continuous intragastric administration for nine weeks. The food intake， body weight， fecal characteristics， and haematochezia were observed and recorded， and disease activity index （DAI） scores were calculated according to scoring criteria. Hematoxylin and eosin （HE） staining was used to observe the histopathological changes in the colon tissues of the mice. Immunohistochemistry was used to determine proliferating cell nuclear antigen-67 （Ki67） expression in the colon tissues， and enzyme-linked immunosorbent assay （ELISA） was used to detect the contents of interleukin-6 （IL-6）， IL-1β， and tumor necrosis factor-α （TNF-α） in the serum of the mice. Flow cytometry was employed to determine the proportion levels of MDSCs， CD4⁺ T cells， and CD8⁺ T cells in the spleen tissues of the mice. The mRNA expressions of MDSC-associated effector molecules， including arginase 1 （Arg1） and inducible nitric oxide synthase （iNOS）， were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. After that， an in vitro co-culture model of MDSCs and CD8⁺ T cells was established， and drug-containing serum of Guizhi Fulingwan was used for intervention. The Flow cytometry was employed to assess the effects of drug-containing serum of Guizhi Fulingwan with different concentrations on the levels of reactive oxygen species （ROS） and iNOS in MDSCs and the proliferation of CD8⁺ T cells. The levels of granzyme B （GZMB） and interferon-γ （IFN-γ） in cell supernatant were detected by ELISA. ResultsCompared with those in the control group， the mice in the model group exhibited significantly reduced body weight， elevated DAI scores， shortened colon length （P<0.01）， increased number of tumors and Ki67 expression （P<0.01）， and significantly elevated contents of IL-6， IL-1β， and TNF-α in the serum （P<0.01）. Significant increases in the number of MDSCs were observed in mouse spleens， alongside marked reductions in the levels of CD4⁺ T and CD8⁺ T cells （P<0.01）. Furthermore， the mRNA expressions of MDSC function-associated effector molecules Arg1 and iNOS were significantly upregulated （P<0.01）. Compared with those in the model group， the mice in the middle-dose Guizhi Fulingwan group exhibited increased body weight and significantly decreased DAI scores （P<0.05， P<0.01）. The mice in the middle- and high-dose Guizhi Fulingwan groups exhibited significantly improved colon shortening， significantly decreased number of tumors and Ki67 expression （P<0.05， P<0.01）， and significantly decreased contents of IL-6， IL-1β， and TNF-α in the serum （P<0.05， P<0.01）. Furthermore， administration of Guizhi Fulingwan markedly reduced MDSC infiltration in the spleen of the mice， with different degrees of increase in the levels of both CD4⁺ T and CD8⁺ T cells （P<0.05， P<0.01）， alongside significant decreases in the mRNA expressions of Arg1 and iNOS （P<0.05， P<0.01）. In vitro cell co-culture shows that administration of drug-containing serum of Guizhi Fulingwan significantly decreases the activity levels of ROS and iNOS in MDSCs and promotes the proliferation of CD8⁺ T cells and the secretion of GZMB and IFN-γ （P<0.05， P<0.01）. ConclusionGuizhi Fulingwan can reduce pro-inflammatory cytokine secretion and inhibit tumor proliferation in the colon tissues of CAC mice. Its potential mechanism may involve reducing MDSC infiltration， enhancing effector T cells， particularly CD8⁺ T cell response， and improving the tumor immunosuppressive microenvironment.

It is considered that lean metabolic associated fatty liver disease （MAFLD） is characte-rized by a state of "lean body but fatty liver". From the perspective of the pathomechanism evolution of "spleen failing to disperse essence， while kidney failing to transform qi"， the disease is systematically treated under the principle that spleen and kidney deficiency as the root and liver constraint with phlegm stasis as the branch. Spleen deficiency with impaired transformation and transportation leads to failure in the distribution of refined substances， initiating lipid turbidity accumulation and obstruction. Kidney dysfunction in qi transformation results in insufficient essence and blood， forming the root of bodily malnourishment. Over time， this further gives rise to liver constraint and loss of dispersing function， disorder in the movement of essential substances， and congealing of phlegm and stasis within hepatic collaterals. The dysfunction of three organs including spleen， kidney and liver constitutes the pathological basis of metabolic disturbances involving qi， blood， body fluids and essence. Treatment should follow the principle of "nourishing the healthy qi leads to spontaneous resolution of pathogenic accumulation"， with three approaches. First， fortifying the spleen and eliminating dampness， using Sini Powder （四逆散） and Erchen Pingwei Powder （二陈平胃散） to restore the transport and transformation function of the middle jiao （焦）， thereby guiding essential substances back to their proper physiological pathways. Second， tonifying the kidney and resolving turbidity， using Jinkui Shenqi Pill （金匮肾气丸） and Effective Integration Decoction （一贯煎） to replenish the lower jiao， promoting the restoration of essence and the transformation of turbid pathogen. Third， soothing the liver and resolving stasis， using Liujunzi Decoction （六君子汤） and Xiaozhi Qinggan Decoction （消脂清肝汤） to vent qi and blood stagnation， thereby interrupting disease progression. Together， these three methods reinforce healthy qi while eliminating pathogen， facilitating the restoration of proper essence transformation and the resolution of lipid turbidity.

Objective:To investigate the clinical characteristics of patients with multiple myeloma(MM)complicated by bone lesions and the risk factors associated with bone lesions.Methods:The clinical data of 294 newly diagnosed MM patients in Gansu Provincial Hospital from January 2017 to June 2021 were retrospectively analyzed.The patients were divided into the bone lesion group(154 cases)and the non-bone lesions group(140 cases)based on the presence of absence of bone lesions at diagnosis.The general data and laboratory parameters were compared between the two groups.The risk factors for bone lesions in MM patients were analyzed by logistic regression analysis,and the characteristic(ROC)curves were plotted to assess the predictive value of each risk factor for the occurrence of bone lesions in MM patients.Results:Compared to the non-bone lesion group,the bone lesion group had significantly higher serum calcium levels and significantly greater proportions of patients with Durie-Salmon(DS)stage Ⅲ,and bone pain(all P＜0.05).Logistic regression analysis showed that elevated serum calcium(OR=5.135,95％CI:1.931-13.653,P=0.001),DS stage Ⅲ(OR=1.841,95％CI:1.019-3.328,P=0.043),and bone pain(OR=8.208,95％CI:4.761-14.151,P＜0.001)were independent risk factors for bone lesions in MM patients.ROC curve analysis showed that serum calcium(AUC=0.619,95％CI:0.555-0.683,P＜0.001)and bone pain(AUC=0.743,95％CI:0.692-0.793,P＜0.001)had predictive value for bone lesions in MM patients.Conclusion:MM patients have a high incidence of bone lesions,and active monitoring and management of risk factors may improve treatment outcomes and prognosis.

Objective:To analyze the clinical manifestations and fundus multimodal imaging features of patients with acute Vogt-Koyanagi-Harada (VKH) syndrome, and provide a reference for early diagnosis of VKH syndrome.Methods:Retrospective analysis was performed on the clinical data and related examinations including spectral-domain optical coherence tomography (SD-OCT), fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) of patients diagnosed with acute VKH syndrome in the Ophthalmology Department of the Beijing Friendship Hospital from January 2017 to December 2022.Results:A total of 17 patients (34 eyes) with acute VKH syndrome were included. SD-OCT showed exudative retinal detachment in all 34 eyes with punctate hyperreflective signals; 26 eyes had choroidal folds, and 14 patients (28 eyes) had " septum-like" structures under the neuroepithelium. FFA early images showed late retinal fluorescence pooling in a multi-lake pattern in all 34 eyes. ICGA was performed in 15 patients (30 eyes), with early images showing hyperfluorescence of choroidal vessels in all 30 eyes; 26 eyes had scattered hypofluorescent lesions in the fundus. Mid-to-late images showed blurred boundaries of choroidal vessels in 28 eyes.Conclusions:Patients with acute VKH syndrome have characteristic manifestations in SD-OCT, FFA, and ICGA. Fundus multimodal imaging can provide important references for the diagnosis of VKH syndrome.

Objective:To investigate the status of leisure crafting and post competence and their correlation among anesthesia specialist nurses.Methods:A convenience sampling method was used to conducted a questionnaire survey on 280 anesthesia specialist nurses at grade A tertiary hospitals in 19 provinces of China. Data were collected using a general information questionnaire, the Chinese version of Leisure Crafting Scale, and the Post Competency Scale for Anesthesia Specialist Nurses. SPSS 24.0 was used for t test and one-way analysis of variance. A Pearson correlation analysis was used to assess relationships between variables. Results:The total score of leisure crafting was (30.41±6.69) and the average score was (3.38±0.74). The total score of post competency was (141.76±21.76) and the average score was (3.73±0.57). A positive correlation was observed between leisure crafting and post competency ( r=0.215, P<0.01). Conclusions:Managers should encourage anesthesia specialist nurses to actively engage in leisure crafting and provide diverse opportunities for leisure crafting to improve their post competence and ultimately the quality of anesthesia nursing.

Objective:To explore the effects of mechanical ventilation（MV）at birth transition on lung pathophysiology and pathobiology in a very preterm animal model.Methods:Based on the model of respiratory distress syndrome（RDS）in very preterm rabbits at gestational age 26（term 31）days well established by the research group using perinatal medication and lung-protective ventilation strategies（very low tidal volume 1-3 mL/kg），we conducted a secondary data analysis. The studied rabbits were re-grouped according to the MV length（≤3 h，3-6 h，6-9 h，9-12 h，and >12 h）. The changes in lung mechanics，histopathology，phospholipid biochemistry，and mRNA relative expression of inflammatory/growth factor in lung tissue were evaluated over the time course of MV. The trend of each variable was tested by ANOVA trend test（ F trend）and Jonckheere-Terpstra trend test（ J-T value）with corresponding P value. Results:With the prolonged MV length，there was improved mean dynamic compliance of respiratory system（ F trend=16.722， P trend<0.001），along with decreased mean peak inspiratory pressure（ F trend =42.226， P trend<0.001）. The content of total phospholipids，disaturated phosphatidylcholine（ J-T=1 222，1 197， P trend=0.018，0.034，respectively）and total protein（ J-T=1 247 ，P trend= 0.009）in bronchoalveolar lavage fluid gradually increased. The wet lung weight in the ≤3 h group was significantly higher than in the other groups（ F=6.819， P<0.001）. The lung injury score（total，or hemorrhage，or inflammation）had progressive exacerbation in the ≤3 h，3-6 h and 6-9 h groups. The lung tissue mRNA expression of major proinflammatory cytokines increased modestly over the time groups in contrast to decreased expression of growth factors，of which the change of keratinocyte growth factor reached statistical significance（ J-T=531， P trend =0.034）. Conclusion:In the 26-day very preterm rabbits，with prolonged MV time，the content of surfactant phospholipid in the alveolar increased gradually，the lung compliance and lung fluid clearance gradually improved. Nevertheless，ventilator-induced lung injury remained evolving. The study warrants further study on the pathogenesis and protective strategies of early postnatal acute lung injury and chronic lung disease.

Objective:To investigate the clinical features, diagnosis and treatment of eso-phageal fistula (EF) after radiofrequency catheter ablation (RFCA) for atrial fibrillation.Methods:The retrospective and descriptive study was conducted. The clinical data of 15 patients with EF after RFCA for atrial fibrillation who were admitted to Beijing Anzhen Hospital of Capital Medical University from January 2020 to December 2024 were collected. There were 11 males and 4 females, aged (64±7)years. All patients underwent surgical treatment. Observation indicators: (1) diagnosis and surgery; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represented as Mean±SD, measurement data with skewed distribution were represented as M (range), and count data were represented as absolute numbers. Results:(1) Diagnodid and surgery. Of the 15 patients, radiofrequency catheter ablation included pulmonary vein isolation plus linear ablation in 13 cases and pulmonary vein isolation alone in 2 cases. The time to postoperative symptom onset of EF in 15 patients was (13±8)days. The main clinical manifestations included persistent chest pain in 14 cases, fever in 12 cases, dysphagia in 2 cases, and neurological symptoms in 2 cases (the same patient could have multiple symptoms). All patients presented with signs of infection of varying severity. Contrast-enhanced chest computed tomography (CT) or pulmonary vein CT angio-graphy revealed mediastinal emphysema, pneumopericardium with pericardial effusion, localized esophageal wall thickening with exudation, abnormalities in the posterior wall of the left atrium, or contrast extravasation in all patients. Cerebral imaging examination showed newly developed cerebral infarcts in 2 patients. The time from symptom onset to surgical intervention was 2(range, 1-10)days.All 15 patients underwent surgical treatment immediately after being diagnosed or highly suspected of EF via multidisciplinary collaboration. Among them, 11 patients with atrial-esophageal fistula (AEF) underwent left atrial defect repair plus left thoracic esophageal repair under cardio-pulmonary bypass through a median sternotomy, 3 patients with simple EF underwent left thoracic esophageal repair, 1 patient with AEF underwent atrial repair plus esophageal exclusion and drainage due to severe mediastinal infection. The diameter of the left atrial defect in the 15 patients was (12±5)mm, and the diameter of the esophageal defect was (11±4)mm. There was no patient cured with conservative treatment or converted to surgical treatment after failed conservative treatment.(2)Postoperative situations.Of the 15 patients, 3 cases developed pulmonary infection and were improved after anti-infective treatment. The duration of postoperative hospital stay was (21±5)days. (3) Follow-up. All 15 patients were followed up for 11(range, 3-18)months. Two of 15 patients died. One patient undergoing atrial repair plus esophageal diversion and drainage died postoperatively due to sepsis and multiple organ failure, and one patient undergoing left thoracic esophageal repair died of acute cardiac tamponade one week after surgery. The remaining 13 patients recovered well, without recurrence or new complications.Conclusions:The main clinical features of esophageal fistula after RFCA for atrial fibrillation include persistent chest pain, fever, accompanying signs of infection. Early contrast-enhanced chest CT or pulmonary vein CT angiography is helpful for diagnosis, and active surgical treatment after confirmation via multidisciplinary collaboration can improve patient prognosis.

Objective To explore the relationship between diffusion kurtosis imaging(DKI)based on MR and macrophage inflammatory protein 1 alpha(MIP-1α)and the prognosis of patient with Parkinson's disease,with constructing a prognostic model.Methods A total of 128 Parkinson's disease patients were selected and randomly divided into training set(n=102)and validation set(n=26)according to the ratio of 8∶2.After one year of treatment with oral levodopa drugs combined with deep brain stimula-tion of subthalamic nucleus,all patients were divided into good prognosis and poor prognosis groups.The serum MIP-1α and MR DKI parameters were compared between the two groups to screen for factors affecting poor prognosis of Parkinson's disease,and a risk prediction model was constructed and validated.Results Among 128 Parkinson's disease patients,53 had poor prognosis,including 44 in the training set and 9 in the validation set.The fractional anisotropy(FA)and mean kurtosis(MK)of the left and right globus pallidus,mini-mental state examination(MMSE)score in the poor prognosis group were significantly lower than those in the good prognosis group,while serum MIP-1α in the poor prognosis group was significantly higher than that in the good prognosis group(P＜0.05).Left globus pallidus FA,left globus pallidus MK,right globus pallidus FA,right globus pallidus MK,MMSE score,and serum MIP-1α were the factors affecting poor prognosis in Parkinson's disease patients(P＜0.05).The sensitivity,specificity,and area under the curve(AUG)of the nomogram model for predicting poor prognosis in Parkinson's disease patients in the training and validation sets were 0.823 and 0.749,0.751 and 0.764,0.821 and 0.802,respectively.Conclusion FA and MK of the left globus pallidus,FA and MK of the right globus pallidus,and serum MIP-1α are associated with poor prognosis in Parkinson's disease patients.Constructing a risk model can help identify the risk of poor prognosis in the early stage.
