Objective:To screen the main characteristic variables affecting the incidence of cardiovascular and cerebrovascular diseases,and to construct the Bayesian network model of cardiovascular and cerebrovascular disease incidence risk based on the top 10 characteristic variables,and to provide the reference for predicting the risk of cardiovascular and cerebrovascular disease incidence.Methods:From the UK Biobank Database,315 896 participants and related variables were included.The feature selection was performed by categorical boosting(CatBoost)algorithm,and the participants were randomly divided into training set and test set in the ratio of 7∶3.A Bayesian network model was constructed based on the max-min hill-climbing(MMHC)algorithm.Results:The prevalence of cardiovascular and cerebrovascular diseases in this study was 28.8％.The top 10 variables selected by the CatBoost algorithm were age,body mass index(BMI),low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC),the triglyceride-glucose(TyG)index,family history,apolipoprotein A/B ratio,high-density lipoprotein cholesterol(HDL-C),smoking status,and gender.The area under the receiver operating characteristic(ROC)curve(AUC)for the CatBoost training set model was 0.770,and the model accuracy was 0.764;the AUC of validation set model was 0.759 and the model accuracy was 0.763.The clinical efficacy analysis results showed that the threshold range for the training set was 0.06-0.85 and the threshold range for the validation set was 0.09-0.81.The Bayesian network model analysis results indicated that age,gender,smoking status,family history,BMI,and apolipoprotein A/B ratio were directly related to the incidence of cardiovascular and cerebrovascular diseases and they were the significant risk factors.TyG index,HDL-C,LDL-C,and TC indirectly affect the risk of cardiovascular and cerebrovascular diseases through their impact on BMI and apolipoprotein A/B ratio.Conclusion:Controlling BMI,apolipoprotein A/B ratio,and smoking behavior can reduce the incidence risk of cardiovascular and cerebrovascular diseases.The Bayesian network model can be used to predict the risk of cardiovascular and cerebrovascular disease incidence.

Objective:Abnormal immune system activation and inflammation are crucial in causing Parkinson's disease.However,we still don't fully understand how certain immune-related genes contribute to the disease's development and progression.This study aims to screen key immune-related gene in Parkinson's disease based on weighted gene co-expression network analysis(WGCNA)and machine learning. Methods:This study downloaded the gene chip data from the Gene Expression Omnibus(GEO)database,and used WGCNA to screen out important gene modules related to Parkinson's disease.Genes from important modules were exported and a Venn diagram of important Parkinson's disease-related genes and immune-related genes was drawn to screen out immune related genes of Parkinson's disease.Gene ontology(GO)analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)were used to analyze the the functions of immune-related genes and signaling pathways involved.Immune cell infiltration analysis was performed using the CIBERSORT package of R language.Using bioinformatics method and 3 machine learning methods[least absolute shrinkage and selection operator(LASSO)regression,random forest(RF),and support vector machine(SVM)],the immune-related genes of Parkinson's disease were further screened.A Venn diagram of differentially expressed genes screened using the 4 methods was drawn with the intersection gene being hub nodes(hub)gene.The downstream proteins of the Parkinson's disease hub gene was identified through the STRING database and a protein-protein interaction network diagram was drawn. Results:A total of 218 immune genes related to Parkinson's disease were identified,including 45 upregulated genes and 50 downregulated genes.Enrichment analysis showed that the 218 genes were mainly enriched in immune system response to foreign substances and viral infection pathways.The results of immune infiltration analysis showed that the infiltration percentages of CD4+ T cells,NK cells,CD8+ T cells,and B cells were higher in the samples of Parkinson's disease patients,while resting NK cells and resting CD4+ T cells were significantly infiltrated in the samples of Parkinson's disease patients.ANK1 was screened out as the hub gene.The analysis of the protein-protein interaction network showed that the ANK1 translated and expressed 11 proteins which mainly participated in functions such as signal transduction,iron homeostasis regulation,and immune system activation. Conclusion:This study identifies the Parkinson's disease immune-related key gene ANK1 via WGCNA and machine learning methods,suggesting its potential as a candidate therapeutic target for Parkinson's disease.

Objective:To investigate the effect of the Ilizarov technique in the treatment of post-traumatic lower extremity shortening with talipes equinovarus.Methods:Clinical data of patients with post-traumatic lower extremity shortening and talipes equinovarus treated by the Ilizarov technique in the Department of Orthopaedics of Xuzhou Renci Hospital from January 2013 to April 2020 were retrospectively analyzed. The annular external fixator was installed on the affected limb according to the Ilizarov principle of external fixation. 3 days after the operation, the internal and lateral screw rods were adjusted at the speed of 2 mm/d to gradually correct the talipes equinovarus. 7 days after surgery, the lower leg was lengthened at a speed of 1 mm/d. After the foot was corrected, the foot external fixator was continued to be worn for 4 to 6 weeks, and then the fixator was removed and the foot was immobilized with a brace for 6 to 8 weeks. The lower leg fixator was removed after the lower extremity length was restored and the bone mineralization at the extension site was good. The length of both lower extremities, angle of talonavicular joint, angle of plantar flexion and dorsal extension of the ankle, and range of motion of ankle were compared before surgery and at the last follow-up. At the last follow-up, the affected feet were scored and rated using the International Clubfoot Study Group (ICFSG) scoring system, which was divided into four grades: excellent, good, medium, and poor. SPSS 25.0 software was used for statistical analysis, and each measurement index and ICFSG score were expressed in Mean±SD. Paired t-test was used to compare the preoperative and last follow-up data, and P<0.05 was considered statistically significant. Results:A total of 31 patients were enrolled, including 17 males and 14 females. The age was 15-18 years old, with an average of 16.5 years old. There were 16 cases on the right side and 15 cases on the left side. The lower extremity shortening was 45-75 mm, with an average of 65 mm. The fixation time of the external fixator was 4.5-6 months after surgery, with an average of 5 months, and the follow-up time was 22-28 months, with an average of 25.5 months. The length of the affected lower extremity recovered, the shape was basically satisfactory, and the plantar gait was restored. At the last follow-up, compared with the preoperative period, the anteroposterior talocalcaneal angle of the foot (23.0°±2.1° vs. 8.5°±2.6°), from lateral talocalcaneal angle the foot (27.0°±4.3° vs. 11.2°±4.4°), ankle plantar flexion angle (24.5°±6.8° vs. 51.1°±6.5°), ankle dorsiflexion angle (5.8°±3.5° vs. -46.8°±7.0°) and ankle range of motion (30.3°±8.2° vs. 4.2°±1.6°) were statistically significant ( P <0.01). ICFSG score: The points at the last follow-up (8.0 ± 4.2) were significantly lower than that before the operation (41.9 ± 5.3) ( P<0.01), of which 18 were excellent, 9 were good, and 4 were medium. Two cases had recurrent deformities in the later stage, and the results were satisfactory after the fusion of the talonavicular joint and calcaneocuboid joint and the anteposition of the posterior tibial tendon in the second stage. There were 4 cases of toe contracture deformity, which did not recur after the release of the flexor digitorum longus tendon at the toe. Anterior ankle impingement was observed in 5 cases and improved after the arthroscopic osteophyte removal. After the lower extremity extension was in place, the external fixator was replaced by the intramedullary nail for walking in 6 patients. The infection of the nail path occurred in 7 cases, which improved after replacement of fixing pins and dressing change of the nail path. Conclusion:The application of the Ilizarov technique in the treatment of post-traumatic lower extremity shortening with talipes equinovarus has the advantages of small trauma and dynamic control of deformity correction, which can achieve good result.

The clinical application of immune checkpoint inhibitors (ICIs) has significantly improved the prognosis of hepatocellular carcinoma (HCC) patients. With the widespread applica-tion of ICIs in HCC, the management of immune-related adverse events (irAE) gained more and more attention. However, the complicated disease characteristics and various combination therapies in HCC throw out challenges to irAE management. Therefore, the editorial board of the 'Chinese expert consensus on the management of immune-related adverse events of hepatocellular carcinoma treated with immune checkpoint inhibitors (2021 edition)' organizes multidisciplinary experts to discuss and formulate this consensus. The consensus focuses on issues related to HCC irAE manage-ment, and puts forward suggestions, in order to improve standardized and safety clinical medication, so as to maximize the benefits of immunotherapy for patients.

OBJECTIVE: To analyze the status and influencing factors of the health literacy(HL) of college students in a comprehensive university. METHODS: A total of 3 360 students from in a comprehensive university of Xinjiang Production and Construction Corps was selected using multi-stage stratified cluster random sampling method. The HL level of college students was investigated and evaluated with self-edited Xinjiang Construction Corps College Students Health Literacy Questionnaire. RESULTS: The HL level of college students was 17.1%. The HL level of medical students was higher than that of non-medical students(35.4% vs 10.0%, P<0.01). Logistic regression analysis results showed that among the medical students in grade three or four, those with medium and excellent academic achievement, and Han nationality had a positive effect on their HL level(P<0.01). Among the non-medical students, female and medicine related optional courses had a positive effect on their HL level(P<0.05). Students in the sophomore year had a negative effect on their HL level(P<0.05). CONCLUSION: There is a big difference in the level of HL between medical students and non-medical students. Medical college students and non-medical college students have different factors affecting HL, medical education is related to improving HL.
