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 explore the role of DNAJC5B in immunotherapy for esophageal squamous cell carcinoma (ESCC). Methods Using the ESCC dataset from The Cancer Genome Atlas (TCGA) database, genes correlated with DNAJC5B expression were identified through Pearson correlation analysis. Subsequently, Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed. Additionally, single-cell RNA sequencing (scRNA-seq) data were utilized to analyze the expression of DNAJC5B in different T-cell subsets. The prognostic value of DNAJC5B was evaluated using Kaplan-Meier survival curves, receiver operating characteristic curves, and Cox proportional hazards models. Results DNAJC5B was highly expressed in patients with advanced-stage ESCC, particularly in males. GO and KEGG analyses revealed a significant correlation between DNAJC5B expression and immune-related processes, such as the adaptive immune response and cell surface receptor signaling pathways. Single-cell analysis results indicated that DNAJC5B expression was positively correlated with immune function, with DNAJC5B predominantly accumulating in CD8+ T cells. Kaplan-Meier survival curves showed that the median survival time for patients with high DNAJC5B expression was 681 days, significantly shorter than the 1 361 days for patients with low expression (P<0.05). Furthermore, univariate and multivariate independent prognostic analyses demonstrated that DNAJC5B was an independent risk factor, with hazard ratios (HRs) of 3.577 and 4.114, respectively (both P<0.05). Conclusion DNAJC5B may play a crucial immunomodulatory role in ESCC, particularly in regulating CD8+ T-cell function and tumor immune escape. These findings support the potential of DNAJC5B as a biomarker for the treatment and prognostic assessment of ESCC.

BACKGROUND: Postoperative pulmonary complications (PPCs) are major adverse events in neurosurgical patients. This study aimed to develop and validate machine learning models predicting PPCs after neurosurgery. METHODS: PPCs were defined according to the European Perioperative Clinical Outcome standards as occurring within 7 postoperative days. Data of cases meeting inclusion/exclusion criteria were extracted from the anesthesia information management system to create three datasets: The development (data of Huashan Hospital, Fudan University from 2018 to 2020), temporal validation (data of Huashan Hospital, Fudan University in 2021) and external validation (data of other three hospitals in 2023) datasets. Machine learning models of six algorithms were trained using either 35 retrievable and plausible features or the 11 features selected by Lasso regression. Temporal validation was conducted for all models and the 11-feature models were also externally validated. Independent risk factors were identified and feature importance in top models was analyzed. RESULTS: PPCs occurred in 712 of 7533 (9.5%), 258 of 2824 (9.1%), and 207 of 2300 (9.0%) patients in the development, temporal validation and external validation datasets, respectively. During cross-validation training, all models except Bayes demonstrated good discrimination with an area under the receiver operating characteristic curve (AUC) of 0.840. In temporal validation of full-feature models, deep neural network (DNN) performed the best with an AUC of 0.835 (95% confidence interval [CI]: 0.805-0.858) and a Brier score of 0.069, followed by Logistic regression (LR), random forest and XGBoost. The 11-feature models performed comparable to full-feature models with very close but statistically significantly lower AUCs, with the top models of DNN and LR in temporal and external validations. An 11-feature nomogram was drawn based on the LR algorithm and it outperformed the minimally modified Assess respiratory RIsk in Surgical patients in CATalonia (ARISCAT) and Laparoscopic Surgery Video Educational Guidelines (LAS VEGAS) scores with a higher AUC (LR: 0.824, ARISCAT: 0.672, LAS: 0.663). Independent risk factors based on multivariate LR mostly overlapped with Lasso-selected features, but lacked consistency with the important features using the Shapley additive explanation (SHAP) method of the LR model. CONCLUSIONS: The developed models, especially the DNN model and the nomogram, had good discrimination and calibration, and could be used for predicting PPCs in neurosurgical patients. The establishment of machine learning models and the ascertainment of risk factors might assist clinical decision support for improving surgical outcomes.

The important studies in the field of extracorporeal life support (ECLS) in 2024 focused on the application of cardiac support technologies in acute myocardial infarction (AMI) with cardiogenic shock (CS): veno-arterial extracorporeal membrane oxygenation (V-A ECMO) has not shown advantages in either short- or long-term outcomes and may increase the risk of bleeding and vascular complications; in contrast, micro-axial flow pumps demonstrate potential in improving mortality. The effects of veno-venous extracorporeal membrane oxygenation (V-V ECMO) combined with prone positioning on severe acute respiratory distress syndrome (ARDS) remain uncertain. The survival benefit of extracorporeal cardiopulmonary resuscitation (ECPR) in out-of-hospital cardiac arrest (OHCA) patients has been further validated. The potential benefits of extracorporeal carbon dioxide removal (ECCO2R) require further investigation. Additionally, new guidelines released in 2024 focus on Neurological monitoring and management during ECMO, as well as the Definition and management of right ventricular injury during veno-venous ECMO. ECMO management requires more refined strategies, including optimized oxygenation targets, anticoagulation, blood transfusion, and weaning strategies to improve patient outcomes.

Objective To investigate the influencing factors of airway mucosal erosion occurrence in child Mycoplasma pneumoniae pneumonia.Methods The medical record data of 162 children patients with Mycoplasma pneumoniae pneumonia hospitalized in the pediatric department of this hospital from February 2023 to February 2024 were analyzed retrospectively.The patients were divided into the mucosal erosion group(n=43)and non-mucosal erosion group(n=119)according to whether or not the mucosal erosion was ob-served by the bronchoscope.The general data,laboratory examination and lung ultrasound images data in the two groups were collected.The pulmonary ultrasound(LUS)was scored.The clinical characteristics,experi-mental indexes and LUS score were compared between the two groups.The stepwise logistic regression was used to analyze the influencing factors of airway mucosal erosion occurrence in Mycoplasma pneumoniae pneu-monia.The receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic efficiency.Results There were statistically significant differences in the fever duration,fever peak,pleural effusion,hos-pitalization duration,neutrophil ratio,levels of C-reactive protein(CRP),lactate dehydrogenase(LDH)and D-dimer,and LUS score had statistical differences between the two groups(P<0.05).The multivariate logistic regression analysis results showed that the fever duration,neutrophil ratio,LDH,D-dimer and LUS score were the influencing factors for airway mucosal erosion occurrence in Mycoplasma pneumoniae pneumonia.The fe-ver duration,neutrophil ratio,LDH,D-dimer and LUS score all had certain predictive value for airway mucosal erosion occurrence in Mycoplasma pneumonae pneumonia,in which the area under the curve(AUC)of LDH,D-dimer and LUS score was larger,and the predictive value was higher(P<0.05).Conclusion The influen-cing factors of airway mucosal erosion in children patients with Mycoplasma pneumoniae pneumonia should be vigilant to improve their prognosis.

BackgroundMany studies have shown that patients with depressive disorder show impairments in prospective memory， while it is deemed necessary for facilitating their social reintegration， and the current research findings are inconsistent regarding the factors affecting prospective memory of patients with depressive disorder. ObjectiveTo explore the impact of target characteristics （emotional valence and salience） on prospective memory in patients with depressive disorder， so as to provide references for the training and recovery of prospective memory function in these patients. MethodsFrom January to December 2022， 53 patients with depressive disorder were recruited from the outpatient department of Inner Mongolia Autonomous Mental Health Center. Meanwhile， 45 healthy individuals were concurrently recruited from surrounding communities as control group. An experiment with a 2 （participant type： depressive disorder， healthy control） ×2 （target salience： salient， non-salient） ×3 （emotional valence： positive， neutral， negative） factorial design was conducted. The positive/neutral/negative emotional pictures from Chinese Affective Picture System （CAPS） were used for emotional stimulation. A dual-task experimental paradigm was adopted， and the response time and accuracy in prospective memory task and ongoing task were recorded for participants with different target characteristics. Results①In the prospective memory task， the main effect of participant type was statistically significant， with the depressive group showing lower accuracy （F=14.892， P<0.01） and longer response time （F=10.642， P=0.002） compared with control group. ② The main effect of target emotional valence on accuracy （F=7.575， P=0.001） and response time （F=3.196， P=0.044） in the prospective memory task was statistically significant. Simple effect analysis revealed that depressive group yielded a shorter response time and higher accuracy rate under negative conditions compared with positive and neutral conditions （P<0.05 or 0.01）. ③ The main effect of target salience on accuracy （F=6.659， P=0.012） and response time （F=10.106， P=0.002） in the prospective memory task was also statistically significant， with higher accuracy and shorter response time for salient targets compared with non-salient targets. ConclusionPatients with depressive disorder demonstrate preferential attention to and processing of negative stimuli in prospective memory tasks， while increasing target salience may facilitate spontaneous processing of prospective memory task in patients with depressive disorder. ［Funded by Inner Mongolia Health Commission Medical Health Science and Technology Project （number， 202202104）］

Objective:To analyze the electroencephalogram(EEG) average relative power spectrum in patients with unipolar and bipolar depression under the eyes-open and eyes-closed resting states.Methods:A total of 38 patients with unipolar depression (UD group), 48 patients with bipolar depression (BD group), and 43 healthy controls (HC group) were recruited from August 2022 to December 2023.The 64-channel EEG was recorded under eyes-open (EO) and eyes-closed (EC) resting states which alternated twice. The Mann-Whitney U test and Kruskal-Wallis H test were performed by SPSS 25.0 software. Results:There were no significant differences in the average relative power of delta and beta bands among the UD, BD and HC groups in all EO and EC states (all P>0.05). The average relative power of theta band in the three groups showed statistically significant differences in all EO and EC states ( H=7.852-12.583, all P<0.05). Further pairwise comparisons showed that in the first EO and EC stage, the average relative power of theta band of the UD and BD groups were significantly higher than that of the HC group (EO1: 0.18(0.17, 0.21), 0.19(0.16, 0.21), 0.16(0.14, 0.18), EC1: 0.15(0.13, 0.21), 0.15(0.13, 0.20), 0.13(0.10, 0.16); all P<0.05).In the second EO and EC stage, the average relative power of theta band of the BD group was significantly higher than that of the HC group (EO2: 0.18(0.15, 0.22), 0.16(0.14, 0.18), EC2: 0.15(0.13, 0.19), 0.13(0.11, 0.16); both P<0.05).There were statistically significant differences in the average relative power of alpha band among the three groups in the first EO and EC stage, as well as the second EC stage ( H=5.027-10.668, all P<0.05). Further pairwise comparisons showed that in the first EO stage, the average relative power of alpha band in the BD group was significantly higher than that in the UD group (0.20(0.16, 0.25), 0.14(0.11, 0.22), P=0.003), and in the following EC stages, the average relative power of alpha band in the UD group was significantly lower than that in the HC group (EC1: 0.40(0.33, 0.46), 0.51(0.40, 0.58), EC2: 0.41(0.35, 0.50), 0.48(0.43, 0.58); both P<0.05). Conclusion:At the initial stage of the resting state, both unipolar and bipolar depression patients demonstrate abnormal theta band activity under the eyes-open and eyes-closed states, while the alpha band activity under the eyes-open condition differs between the two groups of patients. These findings may provide potentially objective biomarkers to assist the diagnosis of unipolar and bipolar depression patients in clinical settings.

OBJECTIVE T o explore the clinical characteristics and risk factors for plastic bronchitis(PB)in the chil-dren with Mycoplasma pneumoniae pneumonia(MPP).METHODS A retrospective case-control study was con-ducted for the medical data of the children with MPP who hospitalized in pediatrics department of Affiliated Hos-pital of Jining Medical College and underwent bronchoscopy and bronchoalveolar lavage from Jan.2023 to Dec.2024.The enrolled children were divided into the PB group and the non-PB group according to the status of complication with PB.The baseline data,clinical characteristics,laboratory test indexes,imaging features,bron-choscopy findings and treatment outcomes were observed and compared between the two groups of children.RESULTS A total of 734 children with MPP were included in the study,131 of whom were assigned as the PB group,and 603 were assigned as the non-PB group.The children were younger[4.83(1.88,7.00)years],the du-ration of fever was longer,the peak temperature was higher[39.50(39.20,39.80)℃],the percentage of compli-cation with pleural effusion was higher(33.59％),the percentage of extrapulmonary organs involved was higher(27.48％),the levels of white blood cells,neutrophils percentage,C-reactive protein(CRP),lactic dehydrogen-ase(LDH),D-dimer(DD)and alanine aminotransferase(ALT)were higher in the PB group than in the non-PB group,and there were significant differences(P＜0.05).There were significant differences in the percentage of mucosal necrosis under bronchoscopy,number of times of treatments assisted by bronchoscopy and length of hospital stay between the two groups(P＜0.05).CONCLUSIONS The MPP children with PB are characterized by younger rage,longer duration of fever,higher peak temperature,higher percentage of complication with pleural effusion,extrapulmonary organs more likely to be involved,more intensive inflammatory reactions and higher percentage of mucosal necrosis under bronchoscopy.Some of the children need to be treated repeatedly with assis-tance of bronchoscopy,and the length of hospital stay is long.

Objective:To address the inefficiency, safety hazards, and resource wastage in traditional medical laboratory management, this study proposes a digital laboratory information management system (LIMS) based on Total Quality Management (TQM) principles. The LIMS has been implemented at the National Center for Geriatric Medicine (Huashan) affiliated with Fudan University.Methods:Centered on the principles of " all-staff participation, whole-process control, and comprehensive management", a multidimensional management framework was developed to integrate personnel, equipment, reagents, and safety protocols. The system incorporated IoT, digital twin, and artificial intelligence (AI) technologies to achieve end-to-end digital control. A layered architecture (physical layer, data layer, model layer, etc.) was designed to integrate functional modules such as full lifecycle equipment management, dual-authentication for hazardous chemicals, and intelligent resource scheduling. A 3D digital twin model was deployed to visualize real-time laboratory operations.Results:Post-implementation, equipment reservation frequency and usage duration at the National Center increased by 114% and 124%, respectively, with no safety incidents reported. Equipment sharing utilization reached 85%, and reagent expiration waste decreased by 30%.Conclusions:The system transforms laboratory management from experience-driven to data-driven by breaking data silos and optimizing collaboration mechanisms. It provides a replicable technical pathway and practical insights for the healthcare industry′s digital transformation. However, further improvements are needed in mobile support and system scalability.

OBJECTIVE: To determine risk factors for cutout failure in geriatric intertrochanteric fracture patients after cephalomedullary nail fixation. METHODS: A retrospective review of 518 elderly patients who underwent cephalomedullary nail fixation for intertrochanteric fractures between January 2008 and August 2018 was conducted, including 167 males and 351 females, age from 65 to 97 years old. All patients were followed up for at least one year after surgery and divided into a healed group and a cutout group based on whether the hip screw cutout occurred. Among all patients, 10 cases experienced hip screw cutout. The general information, surgical data, and radiological data of the two groups were compared, and risk factors influencing hip screw cutout were analyzed. Propensity score matching was then performed on the cutout group based on gender, age, body mass index(BMI), and American Society of Anesthesiologists(ASA), and 40 patients from the healed group were matched at a ratio of 1∶4. Key risk factors affecting hip screw cutout were further analyzed. Multivariable logistic regression analysis was conducted to evaluate associations between variables and cutout failure. RESULTS: There were no statistically significant differences between the healed group and the cutout group in terms of age, gender, BMI, ASA, and AO classification. However, statistically significant differences were observed between the two groups in terms of reduction quality(P=0.003) and tip-apex distance(TAD), P<0.001. Multivariate analysis identified poor reduction quality OR=23.138, 95%CI(2.163, 247.551), P=0.009 and TAD≥25 mm OR=30.538, 95%CI(2.935, 317.770), P=0.004 as independent risk factors for cutout failure. CONCLUSION The present study identified poor reduction quality and TAD≥25 mm as factors for cutout failure in geriatric intertrochanteric fractures treated with cephalomedullary nails. Further studies are needed to calculate the optimal TAD for cephalomedullary nails.
