ObjectiveTo establish a risk recognition model for coronary artery stenosis by using a machine learning method and to identify the key causative factors. MethodsPatients aged ≥18 years,diagnosed with coronary heart disease through coronary angiography from January 2013 to May 2020 in two prominent hospitals in Shanxi Province, were continuously enrolled. Logistic regression,back propagation neural network (BPNN), and random forest(RF)algorithms were used to construct models for detecting the causative factors of coronary artery stenosis. Sensitivity (TPR), specificity (TNR), accuracy (ACC), positive predictive value (PV+), negative predictive value (PV-), area under subject operating characteristic curve (AUC), and calibration curve were used to compare the discrimination and calibration performance of the models. The best model was then employed to predict the main risk variables associated with coronary stenosis. ResultsThe RF model exhibited superior comprehensive performance compared to logistic regression and BPNN models. The TPR values for logistic regression,BPNN,and RF models were 75.76%, 74.30%, and 93.70%, while ACC values were 74.05%, 72.30%, and 79.49%, respectively. The AUC values were:logistic regression 0.739 9; BPNN 0.723 1; RF 0.752 2. Manifestations such as chest pains,abnormal ST segments on ECG,ventricular premature beats with hypertension, atrial fibrillation, regional wall motion abnormalities(RWMA) by color echocardiography, aortic regurgitation(AR), pulmonary insufficiency (PI), family history of cardiovascular diseases,and body mass index(BMI)were identified as top ten important variables affecting coronary stenosis according to the RF model. ConclusionsRandom forest model shows the best comprehensive performance in identification and accurate assessment of coronary artery stenosis. The prediction of risk factors affecting coronary artery stenosis can provide a scientific basis for clinical intervention and help to formulate further diagnosis and treatment strategies so as to delay the disease progression.

OBJECTIVE To evaluate the efficacy and safety of high-dose ilaprazole combined with amoxicillin for newly diagnosed elderly patients with Helicobacter pylori (Hp) infection, and analyze independent risk factors for failure of Hp infection eradication treatment. METHODS Totally 200 cases of newly diagnosed elderly patients with Hp infection in Xinxiang Central Hospital from August 1, 2021 to December 1, 2024 were selected and randomly divided into control group and study group, with 100 cases in each group. The control group was treated with classic quadruple therapy regimen (Amoxicillin capsules+ Clarithromycin tablets+Bismuth potassium citrate tablets+Ilaprazole enteric-coated tablets). The study group was treated with high- dose Ilaprazole enteric-coated tablets+Amoxicillin capsules. All patients were administered medication for 2 weeks. Hp eradication rates in the two groups were compared using intention-to-treat (ITT) and per-protocol (PP) analyses. The incidence of adverse reactions in both groups was also recorded. The multiple-factor Logistic regression analysis was used to identify independent risk factors for failure of Hp infection eradication treatment. RESULTS In ITT and PP analyses, there was no significant difference of Hp eradication rates between the two groups (P>0.05). There was no significant difference in incidence of mild to moderate adverse reactions between the two groups (P>0.05). BMI ≤18.5 kg/m2, BMI >23.9 kg/m2, rural residence, concomitant diabetes and concomitant heart disease were identified as independent risk factors influencing the failure of Hp infection eradication treatment (P<0.05). CONCLUSIONS The efficacy and safety of high-dose ilaprazole combined with amoxicillin are comparable to classic quadruple therapy regimen in treating newly diagnosed elderly patients with Hp infection. Independent risk factors influencing the failure of Hp infection eradication treatment include BMI ≤18.5 kg/m2, BMI >23.9 kg/m2, rural residence, concomitant diabetes and concomitant heart disease.

This paper summarized the key points and methods in terms of the establishment of the guideline working group and the management of conflict of interests, trying to provide reference for the development of clinical practice guidelines for Chinese patent medicine (CPM). The establishment of the working group is the first important step for developing CPM guidelines. Considering the characteristics of the clinical practice guidelines for CPM, this study suggests that the three key elements of ‘multidisciplinarity’, ‘clinical relevance’ and ‘geographical representativeness’ should be put focus on when forming the working group. The guideline advisory committee, clinical expert group, evidence systematic evaluation group, secretary group and the external review group should be established. All group members should clarify the conflict of interest, and the process and management method of the conflict of interest should be clearly reported.

The retrieval and evaluation of evidence is the basis for the development of clinical practice guidelines for Chinese patent medicine. As traditional Chinese medicine has a different development trajectory and utilization characteristics from modern medicine, there is certain differences in terms of evidence composition, retrieval and integration.This paper discussed multi-source body of evidence on Chinese patent medicine based on modern evidence-based medicine and ancient medical literature, and summarized the retrieval strategy as well as the possible problems and solving methods. For different types of evidence on Chinese patent medicine, the corresponding evaluation tools have been recommended, and the order to integrate the evidence based on the quality of the evidence from high to low is suggested. Finally, a multi-source based evidence retrieval-evaluation-integration scheme for Chinese patent medicine has been formed, which will provide a methodological reference for practitioners in the development of clinical practice guidelines for Chinese patent medicine.

Recommendations for Chinese patent medicine (CPM) based on key information on rational drug use are one of the important conditions for enhancing guideline enforceability as well as facilitating guideline implementation. In this study, we discussed in detail of the key information on the rational use of CPM in five aspects, which are dosage, drug discontinuation, drug-drug and drug-food interactions, safety and economy. Following the process of multi-source search, synthesis and prioritization, it is suggested to collect key information on the rational use of CPM from a multi-source search of drug instructions, policy documents, literature, and clinical experts' experiences. Then the searched information should be summarized and prioritized with the principle that taking drug instructions as the basis and other-sources information for check and supplementation. Finally, methodological recommendations for the retrieval and synthesis of key information on rational drug use in guideline recommendations has been formed.

BACKGROUND:Satellite cells are a specific population of adult stem cells contained in skeletal muscle that promote the regenerative reconstruction of injured skeletal muscle,but their specific mechanisms are not well established. OBJECTIVE:To review the regulatory role of satellite cells during skeletal muscle regeneration and the mechanism of interaction between satellite cells and their ecological niche signals,aiming to provide new research ideas and perspectives based on the summary of existing knowledge. METHODS:Web of Science,PubMed,CNKI,WanFang,and VIP databases were searched for literature published between January 2002 and June 2022.English search terms were"muscle,skeletal muscle,muscle injury,stem cells,satellite cells,muscle repair".Chinese search terms were"skeletal muscle,skeletal muscle regeneration,skeletal muscle reconstruction,satellite cells,ecological niche".The 66 included papers were organized and analyzed. RESULTS AND CONCLUSION:(1)Satellite cells exist in skeletal muscle and contribute to both the formation of new muscle fibers after injury and the effective growth of existing adult muscle fibers.(2)After the activation of quiescent satellite cells in satellite cells,the steps of satellite cell proliferation,differentiation and fusion to form muscle fibers during skeletal muscle regeneration are influenced by their intrinsic regulatory effects of different mechanisms.(3)Satellite cells can interact with myofibers,extracellular matrix,skeletal muscle junctions,fibroblast progenitor cells,immune cells and endothelial cells in the ecological niche signal to promote satellite cell activation,proliferation and differentiation to achieve effective skeletal muscle regeneration.(4)Possible breakthroughs in future research include:the division pattern of satellite cells in the body;the mechanisms regulating satellite cell transfer;the specific timing of satellite cell differentiation or self-renewal in vivo;and the interaction mechanisms between satellite cells and skeletal muscle junctions.(5)This review may provide some theoretical reference values for the field of injury reconstruction of skeletal muscle and its innovation.

Objective:To investigate the risk factors and their warning effectiveness for meniscus tear secondary to delayed anterior cruciate ligament (ACL) reconstruction.Methods:A retrospective cohort study was conducted to analyze the clinical data of 114 patients (114 knees) with ACL injury, who were admitted to Affiliated Hospital of Nanjing University of Chinese Medicine from December 2018 to December 2023, including 78 males and 36 females, aged 11-50 years [29(21, 35)years]. The patients were divided into tear group ( n=46) and non-tear group ( n=68) according to whether combined with meniscus tear or not during the surgery. Gender, age, duration of disease, smoking history, Body Mass Index (BMI), cause of injury, mechanism of injury, side of the injury, Beighton score, difference of KT-2000 examination, Tegner activity scale of the knee joint, anterior tibial translation sign, medial posterior tibial slope angle, lateral posterior tibial slope angle, and pivot shift grading of the patients in the two groups were recorded. Correlations between the above-mentioned indicators and occurrence of meniscus tear secondary to delayed ACL reconstruction were assessed. In the meantime, the independent risk factors were determined by univariate and multivariate binary logistic regression analysis. Receiver operating characteristic (ROC) curve and area under curve (AUC) were used to evaluate the warning effectiveness of each risk factor for meniscal tear secondary to delayed ACL reconstruction. Results:Univariate analysis showed correlation of duration of disease, BMI, Tegner activity scale of the knee joint, medial posterior tibial slope angle, lateral posterior tibial slope angle and high-grade pivot shift with occurrence of meniscus tear secondary to delayed ACL reconstruction ( P<0.01). The results of multivariate binary logistic regression analysis showed that the duration of disease ≥14.5 weeks ( OR=1.20, 95% CI 1.05, 1.38, P<0.01), BMI≥26.9 kg/m 2 ( OR=1.36, 95% CI 1.03, 1.81, P<0.05), Tegner activity scale of the knee joint ≥4 points ( OR=2.29, 95% CI 1.18, 4.46, P<0.05), medial posterior tibial slope angle ≥11.2° ( OR=2.27, 95% CI 1.06, 4.89, P<0.05) and high-grade pivot shift ( OR=0.03, 95% CI 0.01, 0.03, P<0.05) were significantly correlated with occurrence of meniscus tear secondary to delayed ACL reconstruction. Results of ROC curve analysis showed that the medial posterior tibial slope angle (AUC=0.86, 95% CI 0.80, 0.93) and duration of disease (AUC=0.85, 95% CI 0.77, 0.92) had good warning value, BMI (AUC=0.78, 95% CI 0.69, 0.87) and Tegner activity scale of the knee joint (AUC=0.73, 95% CI 0.64, 0.83) had ordinary warning value, and the warning value of high-grade pivot shift (AUC=0.60, 95% CI 0.49, 0.71) was the lowest. The combination of the risk factors revealed superior warning effectiveness for meniscus tear second to delayed ACL reconstruction (AUC=0.97, 95% CI 0.96, 1.00). Conclusions:The duration of disease ≥14.5 weeks, BMI ≥26.9 kg/m 2, Tegner score ≥4 points, medial posterior tibial slope angle ≥11.2°and high-grade pivot shift are independent risk factors for meniscus tear secondary to delayed ACL reconstruction. The medial posterior tibial slope angle and duration of disease have good warning value, BMI and Tegner scores have ordinary warning value and high-grade pivot shift has the lowest warning value. The combination of the above risk factors has better warning effectiveness for meniscus tear secondary to delayed ACL reconstruction.
