In the context of the digital-intelligent era of traditional Chinese medicine （TCM）， the lack of clinical thinking is a pressing issue that limits the overall effectiveness of TCM and talent cultivation. The "disease-pulse-syndrome-treatment differentiation" thinking model， originally developed by ZHANG Zhongjing in the Treatise on Cold Damage and Miscellaneous Diseases （Shang Han Za Bing Lun）， has served as a guideline and paradigm followed by generations of medical practitioners. This study aims to construct a digitalized "disease-pulse-syndrome-treatment differentiation" thinking system， develop a digital assessment system， and implement it for practical application. The goal is to recommend a digitalized assessment model for TCM and provide a reference for the integrated innovation of talent cultivation in medicine， education， and research. First， based on the complex diagnostic and treatment framework of the Treatise on Cold Damage Diseases （Shang Han Lun）， the research team previously established a "process" + "result" thinking model that included four processes and ten steps. This study integrates knowledge unit theory and digital technology to create a digital system for "disease-pulse-syndrome-treatment differentiation" with a dual-control model of "process control" and "result control". The system consists of 46 items across three categories： knowledge body （W=20%）， knowledge element （W=30%）， and knowledge element associations （W=50%）. Second， a mixed-methods research design was employed， combining qualitative and quantitative approaches. The Delphi method was used to establish hierarchical levels and screen items， while the analytic hierarchy process （AHP） was used to assign weights. Expert surveys were conducted to reach a consensus and further validate the rationale and necessity of the system. Finally， based on the system architecture and integrating key computer technologies， a digital assessment system for "disease-pulse-syndrome-treatment differentiation" was developed. The Treatise on Cold Damage Diseases （Shang Han Lun） was used as a case study to validate the system's feasibility. Statistical results showed that the difficulty level of the assessment question bank was moderate （DL ranging from 0.65 to 0.89）， with good discrimination （D>0.4）， and reasonable reliability and validity （Cronbach's α=0.84， KMO=0.72， Bartlett's test P<0.01）. The system can perform process-oriented evaluations of candidates' thinking in "disease-pulse-syndrome-treatment differentiation" and effectively achieve the goal of clinical thinking assessment through a combination of "process control" and "result control". The examination system offers three major advantages. It standardizes， objectifies， and streamlines the assessment of thought processes， facilitates the organic transformation of TCM education from outcome-based education to thinking-based education， and from exam-oriented education to competency-oriented education， and promotes the practical transformation of TCM assessments from qualitative to quantitative evaluation， as well as from theory to practice. In summary， this system not only represents a technological upgrade to traditional examinations but also empowers the cultivation and assessment of clinical talent in the digital-intelligent era， demonstrating broad application prospects.

ObjectiveSerum metabolomics of acute lung injury（ALI） in rats was conducted using ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS） to explore the similarities and differences in the mechanism of Qingqiao（harvested when the fruits of Forsythiae Fructus were initially ripe and still green in color） and Laoqiao（harvested when the fruits of Forsythiae Fructus were ripe） in the treatment of ALI. MethodA total of 24 SD male rats were acclimatized and fed for 1 week， 6 of them were randomly selected for the blank group and 18 for the experimental group. The ALI model was induced in the experimental group by tracheal intubation with lipopolysaccharide（LPS）. After successfully constructing the ALI model， these rats was randomly divided into model group， Qingqiao group and Laoqiao group， with 6 rats in each group. The Qingqiao and Laoqiao groups were administered orally once a day at a dose of 1.5 g·kg^-1， while the blank and model groups received an equivalent volume of saline for 3 consecutive days. The pathological conditions of rat lung tissues were comprehensively assessed by hematoxylin-eosin（HE） staining， wet-to-dry mass ratio（W/D） of lung tissues， and protein concentration in rat bronchoalveolar lavage fluid（BALF）. The levels of interleukin（IL）-6， IL-1β and tumor necrosis factor（TNF）-α in BALF were quantified using enzyme-linked immunosorbent assay（ELISA）. UPLC-Q-TOF-MS was used to identify and analyze the chemical compositions of Qingqiao and Laoqiao， and serum metabolomics of rats in each group was analyzed， combined with multivariate statistical analysis with variable importance in the projection（VIP） value>1， P<0.05 from t-test， and fold change（FC）≥1.5 or FC≤0.5 to screen the differential metabolites Qingqiao and Laoqiao for the treatment of ALI. The Kyoto Encyclopedia of Genes and Genomes（KEGG） database was used in combination with MetaboAnalyst for the metabolic pathway analysis of the screened differential metabolites. ResultCompared with the blank group， rats in the model group exhibited enlarged alveolar lumen， ruptured alveoli， interstitial hemorrhage， bronchial exudation of a large number of neutrophils and erythrocytes， and a significant increase in the protein concentration in the BALF and the W/D value of the lung tissues（P<0.01）. In contrast， compared with the model group， rats in the Qingqiao group and the Laoqiao group showed reduced bronchial hemorrhage in the lungs， and the protein concentration in the BALF and the W/D value of the lung tissues were significantly decreased（P<0.01）， the lung injury was significantly alleviated， but more obvious in the Qingqiao group. Compared with the blank group， the expression levels of IL-6， IL-1β and TNF-α in the BALF of the model group were significantly higher（P<0.01）. Additionally， compared with the model group， the expression levels of IL-6， IL-1β and TNF-α in the Qingqiao and Laoqiao groups were significantly lower（P<0.01）. The chemical composition analysis of Qingqiao and Laoqiao revealed that 63 components were detected in Qingqiao and 55 components were detected in Laoqiao， with 47 common components， 16 components unique to Qingqiao and 8 components unique to Laoqiao. Characterizing the differences in serum metabolomics in rats， 19 and 12 metabolites were called back by Qingqiao and Laoqiao， respectively. The metabolic pathway enrichment analysis showed that Qingqiao exerted its therapeutic effects by affecting 6 key metabolic pathways， including linoleic acid metabolism， phenylalanine metabolism， phenylalanine， tyrosine and tryptophan biosynthesis， glycerophospholipid metabolism， α-linolenic acid metabolism， and arachidonic acid metabolism， and Laoqiao exerted therapeutic effects by affecting 6 key metabolic pathways， including linoleic acid metabolism， arachidonic acid metabolism， sphingolipid metabolism， phenylalanine metabolism， ascorbate and aldarate metabolism， and glycerophospholipid metabolism. ConclusionQingqiao and Laoqiao have therapeutic effects on ALI， and Qingqiao is more effective. Both of them can play a therapeutic role in ALI by regulating amino acid metabolism and lipid metabolism， but the metabolic pathways affected by them are different.

Objective:To investigate the current status of pertussis laboratory diagnosis and confirmed pertussis cases reporting in Shaanxi Province, and evaluate the quality of case reports.Methods:The information of confirmed pertussis cases reported in Shaanxi Province from January to July 2022 was collected through the China Disease Control and Prevention Information System. The laboratory diagnostic methods and pertussis vaccine immunization history of confirmed cases were investigated, and the descriptive epidemiological method was used for statistical description.Results:Of the 164 confirmed cases of pertussis reported from January to July 2022, two were not tested in the laboratory and 162 were tested in the laboratory. The proportions of different detection methods were 1.85% (3/162) of isolation and culture, 31.48% (51/162) of serum antibody IgG, 14.20% (23/162) of serum antibody IgM, 49.38% (80/162) of serum antibody PCR and 3.09% (5/162) of serum antibody IgM+ PCR. Among the 79 serological positive cases, 12 cases (15.19%)had no history of pertussis immunization, and 15 cases (18.99%), 11 cases (13.92%) and 41 cases (51.90%) had the time interval from vaccination to detection of <1 year, 1-3 years and >3 years, respectively. Based on the analysis of laboratory testing methods and vaccination history, 38 cases were misdiagnosed/misreported among 164 cases, with a misdiagnosis or misreported rate of 23.17%. There were 17, 12 and 9 cases of misdiagnosis/misreport in 0-2 years old group, 3-6 years old group and≥7 years old group, and the misdiagnosis or misreported rates were 27.42%(17/62), 26.67%(12/45) and 15.79%(9/57), respectively.Conclusions:The selection of pertussis laboratory testing methods in some medical institutions in Shaanxi Province is incorrect, which leads to a certain proportion of misdiagnosis or misreport, and it is necessary to further strengthen the training and standardization.

Objective:To translate the Hip Preservation Surgery Expectations Survey (HPSES) into Chinese and test its reliability and validity.Methods:This study strictly followed the principles of Brislin translation, back translation, and cross-cultural adaptation to form a simplified Chinese version of HPSES. From September 2019 to July 2021, a survey was conducted using convenience sampling method to select 215 patients from the Department of Orthopedics of the Affiliated Hospital of Qingdao University who underwent hip preservation surgery to test the reliability and validity of the Chinese version of HPSES. This study used critical ratio determination and correlation analysis for item analysis, and used content validity index and structural validity to evaluate the validity of the scale, and the reliability of the scale was evaluated using Cronbach's α coefficients and half reliability.Results:The Chinese version of HPSES extracted 4 common factors, totaling 22 items, with a cumulative total variance contribution rate of 63.696%. The content validity index at the scale level was 0.97, and the content validity index at the item level was 0.83 to 1.00. The results of confirmatory factor analysis showed that the fit of the scale was good. The total Cronbach's α coefficient of the scale was 0.873, and Cronbach's α coefficients for each dimension ranged from 0.834 to 0.868. The overall Guttman half reliability coefficient of the scale was 0.840, and the Guttman half reliability coefficients for each dimension were 0.755 to 0.865.Conclusions:The Chinese version of HPSES has good reliability and validity, which can be used to evaluate the expected outcomes of patients undergoing hip preservation surgery, facilitating medical and nursing staffs to provide targeted preoperative health education and rehabilitation guidance to patients, and improving patients satisfaction.
