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 develop a precise method for analyzing urinary peptides based on electromembrane extraction(EME)combined with liquid chromatography-tandem mass spectrometry(LC-MS/MS),and to evaluate its potential applicability in tumor biomarker screening.Methods A total of 15 disease-associated peptides were selected as the target analytes.A supported liquid membrane(SLM)composed of n-octanol containing 5%di(2-ethylhexyl)phosphate was employed,with the donor phase being a 1∶1 mixture of urine and 100 mmol/L formic acid and urine,and the acceptor phase being 20 mmol/L formic acid containing 50%dimethyl sulfoxide(DMSO).After EME at 40 V for 15 min,the acceptor phase solution was analyzed by LC-MS/MS.Subsequently,the method,EME combined with LC-MS/MS(EME-LC-MS/MS),was preliminarily validated utilizing urine samples from 12 healthy controls and 7 patients with urinary system tumors.Results All 15 peptides exhibited excellent linearity in the range of 0.1-100.0 ng/mL(r≥0.995),with the limits of detection(LODs)being 0.01-0.50 ng/mL and the limits of quantification(LOQs)being 0.03-1.50 ng/mL.The spiked recoveries ranged from 21.0%to 71.2%,with relative standard deviations(RSDs)of 0.8%-20.0%(n=3).Small-sample analysis of clinical specimens revealed that the concentration of bradykinin 1-5 in the urine were significantly higher in tumor patients(median:0.65 ng/mL)than that in healthy controls(median:0.37 ng/mL)(P<0.05),suggesting its potential as a specific biomarker for urinary system tumors.Conclusion The EME-LC-MS/MS method established in the study features simplicity,high efficiency,and high sensitivity,enabling precise determination of trace-level peptides in urine samples.Moreover,this approach provides a reliable methodological basis for disease biomarker screening and promotes the clinical application of electromembrane extraction.

Objective To investigate the value of serum aquaporin 1(AQP1)level combined with extra-vascular lung water index(EVLWI)in assessing the severity and prognosis of sepsis causing acute respiratory distress syndrome(ARDS).Methods 268 patients with sepsis-induced ARDS(ARDS group)and 55 patients with sepsis alone(sepsis alone group)admitted to our hospital from January 2020 to December 2023 were selected.Patients with sepsis-induced ARDS were divided into 89 mild,109 moderate,and 70 severe groups according to the oxygenation index(OI),and 104 deaths and 164 survivors according to the 28 d prognosis.Detection of serum AQP1 levels and calculation of EVLWI.Using Spearman's method,the correlation between serum AQP1 level,EVLWI and OI in patients with sepsis-induced ARDS;the establishment of a logistic regression model to determine the factors of sepsis-induced mortality in patients with ARDS;and the plotting of ROC curves to evaluate the value of serum AQP1 level in combination with EVLWI for its assessment.Results Compared with the simple sepsis group,serum AQP1 level was reduced and EVLWI was increased in the ARDS group(P<0.05).AQP1 levels were sequentially lower and EVLWI sequentially higher in the mild,moderate,and severe groups(P<0.05).Serum AQP1 levels were positively correlated with OI in patients with sepsis-induced ARDS,and EVLWI was negatively correlated with OI in patients with sepsis-induced ARDS(P<0.05).The 28 d mortality rate in 268 patients with ARDS due to sepsis was 38.81%(104/268).The independent protective factors for death in ARDS patients with sepsis were elevated OI(OR=0.984,95%CI:0.976～0.992)and elevated AQP1(OR=0.761,95%CI:0.677～0.854),and the independent risk factors were increased SOFA score(OR=1.367,95%CI:1.142～1.636)and elevated blood lactate(OR=2.515,95%CI:1.689～3.745),and elevated EVLWI(OR=1.559,95%CI:1.290～1.885)(P<0.05).The AUC predicted by serum AQP1 level combined with EVLWI was 0.887(95%CI:0.843～0.923),which was greater than the AUC predicted by serum AQP1 level,and EVLWI alone,which was 0.792(95%CI:0.738～0.839),and 0.807(95%CI:0.754～0.852)(P<0.05).Conclusion Decreased serum AQP1 levels and elevated EVLWI were associated with increased severity and poor prognosis in patients with sepsis-induced ARDS,and serum AQP1 levels in combination with EVLWI were of high value in assessing the prognosis of patients with sepsis-induced ARDS.

There are many bidirectional communication and crosstalk between microbes and host plants. The plant-pathogen interaction directly affects the survival of host plants, while the interaction between plants and their probiotics benefits both. Plant miRNA responds quickly to pathogenic or beneficial microbes when they enter the plant tissues, while microbes also produce miRNA-like RNA (milRNA) to affect plant health. These means miRNA or milRNA is an important fast-responding molecular mediator in plant-microbe interactions, and these internal mechanisms have been better understood in recent years. This review summarized the regulatory roles of miRNA in plant-pathogens and plant-probiotics interaction. The regulatory role of miRNA in disease resistance of host plants during plant-pathogens interaction, and the regulatory role of miRNA in promoting host growth and development during plant-probiotics interaction, as well as the cross-kingdom regulatory role of milRNA in host plants, were discussed in-depth.

Digital and intelligent technology is an important driving force to promote the transformation and innovation of medical service mode and improve service quality. In February 2020, Peking Union Medical College Hospital established an intelligent outpatient pre-admission medical history collection system in order to improve the intelligent level of clinical application business system and the medical experience of outpatients.The system consisted of artificial intelligence capability layer, application service layer, capability resource layer and user application layer and hardware technology architecture. By docking with the hospital information system and using mobile terminal App, patients could submit pre-admission medical history information by themselves, and generate structured patient history for the visiting doctors to call. By November 2021, the pre-admission medical history collection system had covered 80% of the departments of the hospital, serving 1.68 million people in total, and the patient filling rate had reached 60%. The duration of patient′s medical history collection and the duration of doctor′s outpatient electronic medical record writing had been continuously shortened, greatly improving the efficiency of outpatient medical services.

Esophageal squamous cell carcinoma(ESCC)is a major histological subtype of esopha-geal cancer with a poor prognosis.Although several serum metabolomic investigations have been reported,ESCC tumor-associated metabolic alterations and predictive biomarkers in sera have not been defined.Here,we enrolled 34 treatment-naive patients with ESCC and collected their pre-and post-esophagectomy sera together with the sera from 34 healthy volunteers for a metabo-lomic survey.Our comprehensive analysis identified ESCC tumor-associated metabolic alterations as represented by a panel of 12 serum metabolites.Notably,postoperative abrosia and parenteral nutrition substantially perturbed the serum metabolome.Furthermore,we performed an examina-tion using sera from carcinogen-induced mice at the dysplasia and ESCC stages and identified three ESCC tumor-associated metabolites conserved between mice and humans.Notably,among these metabolites,the level of pipecolic acid was observed to be progressively increased in mouse sera from dysplasia to cancerization,and it could be used to accurately discriminate between mice at the dysplasia stage and healthy control mice.Furthermore,this metabolite is essential for ESCC cells to restrain oxidative stress-induced DNA damage and cell proliferation arrest.Together,this study revealed a panel of 12 ESCC tumor-associated serum metabolites with potential for monitor-ing therapeutic efficacy and disease relapse,presented evidence for refining parenteral nutrition composition,and highlighted serum pipecolic acid as an attractive biomarker for predicting ESCC tumorigenesis.
