The rapid development of artificial intelligence （AI） technology provides new opportunities for the modernisation of traditional Chinese medicine （TCM） diagnosis. By analysing the foundation， research progress and difficulties of the combination of AI and TCM diagnosis， it is concluded that AI has made remarkable development in intelligence-driven modernization of TCM tongue diagnosis， pulse diagnosis， listening and smelling diagnosis and text processing， and there are useful explorations in the field of constructing data-driven TCM diagnostic model and multidisciplinary integration of TCM diagnostic models. However， the current integration of AI technology in TCM diagnosis still faces many challenges， such as the scarcity and uneven quality of clinical data， the limited ability of AI algorithms to express TCM thinking model of syndrome differentiation and empirical knowledge， and the possible existence of ethical and privacy issues. By systematically sorting out the current research status and development direction of AI-empowered TCM diagnostics， it is proposed to promote the application of AI technology in TCM diagnostics in four aspects， namely， strengthening the construction of TCM big data and talent cultivation， encouraging cross-disciplinary cooperation， improving the legal and ethical framework， and promoting the popularity of the technology in primary care， so as to enhance the modernisation of TCM diagnostics.

ObjectiveTo analyze the changes in the degree of coordination of China's major epidemic prevention and control efforts before and after the outbreak of the Corona Virus Disease 2019 (COVID-19), so as to explore the impact of epidemic prevention and control measures on coordination dynamics. MethodsA total of 3 864 policy documents related to epidemic prevention and control from January 2000 to December 2020 across 31 provinces (autonomous regions, and municipalities) in China were systematically collected. Contents specific to collaborative and cooperative efforts were extracted, and the extent of interdepartmental coordination were quantified to assess the effectiveness of epidemic prevention and control efforts. Wilcoxon signed-rank test was adopted to statistically analyze the differences between the indicators before and after the epidemic. ResultsThe average overall coordination level for major epidemic prevention and control in 31 provinces (autonomous regions, and municipalities) increased from 43.06% to 97.62%, and the average coordination levels in the eastern, central, and western China soared from 42.29%, 37.50%, and 47.46%, to 98.81%, 96.20%, and 97.46%, respectively, with statistically significant differences (all P<0.05). In terms of department categorization, coordination levels in the professional departments and the key support departments peaked at 100.00%, while other support departments rose to 95.43%, with an increase of 77.15%, 181.85%, and 139.89%, respectively, exhibiting noteworthy statistically significant differences (all P<0.001). ConclusionThe scope of coordination departments of China’s major epidemic prevention and control exists a remarkable surge following the COVID-19 outbreak, notable heightened coordination is particularly observed among the key support departments. Future endeavors should prioritize the roles played by diverse departments in epidemic prevention and control, enhancing both the clarity of departmental responsibilities and the effectiveness of interdepartmental coordination.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

ObjectiveUsing the Delphi method and analytic hierarchy process （AHP） to screen diagnostic items for qi stagnation syndrome and determine their weights， providing a reference for the development of a diagnostic scale of qi stagnation syndrome. MethodsLiterature related to qi stagnation syndrome were screened from databases including CNKI， Wanfang， VIP， SinoMed （from inception to October 31， 2020）. Through systematic review of literature and expert discussions， the information on the four examinations of traditional Chinese medicine were organized and an item pool was constructed. The Delphi method was used to screen the item indicators， while the AHP was employed to determine their weights. Statistical methods such as mean value， full score ratio， rank sum， unimportant percentage， and coefficient of variation were used for item screening， with the weights calculated by AHP serving as the item weights. ResultsA total of 235 articles and books were included for analysis， resulting in an item pool of 16 items. After three rounds of expert consultation， a total of 84 valid questionnaires were collected， with a total expert enthusiasm coefficient of 99% and authority coefficient of 0.86， 0.84， 0.83， respectively， and the coordination coefficients were 0.45， 0.49， and 0.29， respectively. Through the statistics analysis， 8 diagnosis items were screened out， including distension （stuffi-ness） or distending pain or scurrying pain， wiry pulse， depressed emotions， frequent sighing， deep and wiry pulse， irritability， pale red tongue， and thin white coating. The AHP showed that the order of weights of the first-level indicators from high to low was clinical symptoms， pulse manifestation， and tongue manifestation； the order of weights of the second-level indicators from high to low was distension （stuffiness） or distending pain or scurrying pain， wiry pulse， depressed emotions， frequent sighing， deep and wiry pulse， irritability， pale red tongue， and thin white coating. ConclusionBy applying the Delphi method and AHP to analyze and evaluate the diagnostic items for qi stagnation syndrome， key diagnostic items were screened and their weights determined， laying the foundation for the development of a diagnostic scale for qi stagnation syndrome.

Objective:To analyze the effect of long-term care insurance on the incidence of falls in old people with disability, and the modification effect of different living arrangements.Methods:Based on the discharge diagnosis records of the hospitalization in urban residents who applied for long-term care insurance in Chengdu from July 2014 to June 2021, those who received long-term care insurance were selected as the intervention group and those who received no long-term care insurance were selected as the control group, the changes in the incidence of falls before and after the long-term care were analyzed using difference-in-differences method, and the modification effects of different living arrangements were explored using stratified analysis.Results:Long-term care insurance significantly reduced the risk for monthly incidence of falls in older adults [average treatment effects on treated (ATT) = -1.21% (95% CI: -1.82%--0.60%)], and the effect increased over time (ATT=-1.26%, 95% CI: -1.93%--0.59%). Long-term care insurance had a significant effect on reducing the incidence of falls in old people living with spouses/family members (ATT=-0.92%, 95% CI: -1.47%--0.37%) and in nursing facilities/hospitals (ATT=-2.10%, 95% CI: -3.81%--0.40%), but it had no significant effect in those living alone. Conclusions:Long-term care insurance can effectively reduce the incidence of falls in old people with disability, showing a positive effect. Living with family members or in nursing facilities/hospitals has a modification effect of the implementation of long-term care insurance policy. It is necessary to pay attention to key populations in the future and expand the coverage of long-term care insurance.

Carpal tunnel syndrome(CTS)is one of the most common peripheral nerve entrapment disorders,the elevated pressure in the carpal tunnel,high-intensity activities and obesity are the main causes,and the patients with mild to moderate CTS are more prevalent.The main pathogenesis of CTS involves the increasing of carpal tunnel pressure and impaired local blood oxygen supply leading to reduced nerve conduction.Currently,the clinical treatment methods for mild to moderate CTS mainly include surgical and nonsurgical treatments.Nonsurgical treatment is the preferable choice for the patients with mild to moderate CTS.The western medical treatment primarily rely on oral medications,but their long-term use is limited due to the certain adverse effects;the local blockade and extracorporeal shock wave therapies show better efficacy for the patients with frequent activities and severe symptoms;the traditional Chinese medicine treatment also becomes a choice for some CTS patients due to their advantages of less pain,lower medical costs,and significant effectiveness.This study reviews the recent advancements in the pathogenesis and treatment of mild to moderate CTS,in order to design the personalized treatment methods for the mild to moderate CTS patients based on their specific conditions in clinical settings and provide the references for precise treatment of the mild to moderate CTS patients.

Objective To study the diagnostic value of miR-126 and ICAM-1 in peripheral blood endo-thelial microparticles(EMPs)of the patients with acute myocardial infarction(AMI).Methods A total of 45 patients with definitely diagnosed AMI in this hospital from September 2021 to June 2022 were selected as the AMI group.Other 45 healthy subjects in the same age group and sex were selected as the control group.Be-fore coronary angiography,the patient's peripheral blood was collected,and the flow cytometry was used to conduct the qualitative and quantitative analysis on EMPs.The expression levels of miR-126 and ICAM-1 in EMPs were determined by using fluorogenic quantitative PCR and ELISA.The receiver operating characteristic(ROC)curve was adopted to evaluate the diagnostic value of the related indicators for AMI.Results There was no statistically significant difference in the general data such as age,gender and BMI between the two groups(P＞0.05).The biochemical indicators such as PLT,BUN,TC,TG and HDL-C had no statistical difference between the two groups(P＞0.05).The expression level of miR-126 in the AMI group was significantly lower than that in the control group,the expression level of ICAM-1 in the AMI group was higher than that in the control group,and the differences were not statistically significant(P＜0.05).The miR-126 expression level in the AMI group was lower than that in the control group,the ICAM expression level was higher than that in the control group,and the differences were statistically significant(P＜0.05).The multivariate logistic regression results showed that miR-126,ICAM-1 and CK-MB had the independent correlation with the AMI occurrence(P＜0.05).The area under the curve(AUC)of mir-126 for diagnosing AMI was 0.813(95％CI:0.725-0.903,P＜0.001),which of ICAM-1 was 0.848(95％CI:0.764-0.933,P＜0.001),and which of miR-126 and ICAM-1 combination diagnosis was 0.922(95％CI:0.870-0.946,P＜0.001).Conclusion The miR-126 and ICAM-1 expression levels in EMPs have the independent correlation with AMI,and the both have the di-agnostic value for AMI.

Objective     To investigate the perioperative clinical effects and follow-up results of minimally invasive coronary artery bypass grafting (MICS CABG) versus conventional coronary artery bypass grafting (CABG) in thoracotomy. Methods     The patients who received off-pump CABG in Beijing Anzhen Hospital from January 2017 to October 2021 were collected. Among them, the patients receiving MICS CABG performed by the same surgeon were divided into a minimally invasive group, and the patients receiving median thoracotomy were into a conventional group. By propensity score matching, preoperative data were balanced. Perioperative and postoperative follow-up data of the two groups were compared. Results     A total of 890 patients were collected. There were 211 males and 28 females, aged 60.54±9.40 years in the minimally invasive group, and 487 males and 164 females, aged 62.31±8.64 years in the conventional group. After propensity score matching, there were 239 patients in each group. Compared with the conventional group, patients in the minimally invasive group had longer operation time, shorter drainage duration, less drainage volume on the first postoperative day, shorter postoperative hospital stay, and lower rate of positive inotropenic drugs use, while there was no statistical difference in the mean number of bypass grafts, ICU stay, ventilator-assisted time, blood transfusion rate or perioperative complications (P>0.05). During the median follow-up of 2.25 years, there was no statistical difference in major adverse cardiovascular and cerebrovascular events, including all-cause death, stroke or revascularization between the two groups (P>0.05). Conclusion    Reasonable clinical strategies can ensure perioperative and mid-term surgical outcomes of MICS CABG not inferior to conventional CABG. In addition, MICS CABG has the advantages in terms of postoperative hospital stay, postoperative drainage volume, and rate of positive inotropic drugs use.

ObjectiveTo study the effect of Guizhi Shaoyao Zhimutang （GSZMD） on cartilage destruction in mice with collagen-induced arthritis （CIA） and its mechanism. MethodThirty-six DBA/1 mice in SPF grades were randomly divided into 6 groups， namely， the normal group， the model group， the methotrexate （MTX） group， the low-dose GSZMD group， the medium-dose GSZMD group， and the high-dose GSZMD group. Except the normal group， mice in the other 5 groups were used to establish the model of CIA by secondary immunization. The mice were given normal saline， MTX （1.5 mg·kg^-1， 2 times a week）， and low， medium， and high-doses GSZMD （6.3， 12.6， 25.2 g·kg^-1·d^-1） by intragastric administration on the day of the onset of hind limb swelling for 4 weeks. The changes in the degree of foot swelling of mice in each group were observed and recorded. The content of matrix metalloproteinase （MMP）-1， MMP-3， MMP-9， and MMP-13 in serum was determined by enzyme-linked immunosorbent assay （ELISA）. The pathological changes in the ankle joint were observed by hematoxylin-eosin （HE） staining， and the cartilage destruction was observed by red fast green staining. The protein expression of the Janus kinase 2/signal transducer and activator of transcription 3 （JAK2/STAT3） signaling pathway in ankle joints were detected by Western blot. ResultAs compared with the normal group， the degree of foot swelling， the content of MMP-1， MMP-3， MMP-9， and MMP-13 in serum and the expression levels of phosphorylation （p）-JAK2/JAK2 and p-STAT3/STAT3 in ankle joints of the model group were increased （P<0.01）， and the joint damage was aggravated. As compared with the model group， the degrees of foot swelling of the mice in the MTX group and the low， medium， and high-dose GSZMD group were reduced （P<0.05， P<0.01）， and the content of MMP-1， MMP-3， MMP-9， and MMP-13 in serum was decreased （P<0.05， P<0.01）. The pathological joint damage was alleviated， and the expression levels of p-JAK2/JAK2 and p-STAT3/STAT3 in ankle joints were decreased in the MTX group and GSZMD groups （P<0.05， P<0.01）. ConclusionGSZMD can reduce the degree of joint swelling in mice with CIA， inhibit the expressions of MMP-1， MMP-3， MMP-9， and MMP-13， and alleviate the destruction of articular cartilage. Its mechanism is related to the JAK2/STAT3 signaling pathway.
