Methods The clinical and imaging data of MMD with stroke patient (age 18 to 45 years old) between January 2020 and December 2021 who were admitted to the Fifth Medical Center of PLA General Hospital were retrospectively analyzed. The MMD patients with stroke were divided into hemorrhagic stroke and ischemic stroke groups, imaging and clinical features of patients with different stroke types were compared. The MMD patients without stroke during the same period were selected as the control group, and multivariate logistic regression analysis was used to analyze the risk factors of hemorrhagic stroke and ischemic stroke in young MMD patients. Results A total of 108 patients with stroke were enrolled, including 22 cases (20.4%) of hemorrhagic stroke and 86 cases (79.6%) of ischemic stroke. A total of 104 subjects in control group were included. In hemorrhagic stroke group, there were 12 cases (54.5%) intraventricular hemorrhage, 7 cases (31.8%)of parenchymal hemorrhage, 3 cases (13.6%) of subarachnoid hemorrhage. In ischemic stroke group, there were 21 cases (24.4%) of larger artery infarction type, 36 cases (41.9%) of hemodynamic infarction type, and 29 cases (33.7%) of perforating artery infarction type. There were statistical differences in gender and the percentage of aneurysms between hemorrhage stroke group and ischemic stroke group. Multivariate logistic regression analysis showed that aneurysm was a risk factor for hemorrhagic stroke in young MMD patients (OR 10.569, 95%CI 1.524-73.274, P=0.017); age increasing (OR 1.058, 95%CI 1.004-1.115, P=0.034), Suzuki stage (OR 1.363, 95%CI 1.037-1.793, P=0.027) and diabetes mellitus (OR 4.005, 95%CI 1.766-9.080, P=0.001) were independent risk factors for ischemic stroke in young MMD patients. Conclusions The main type of stroke in young MMD patients is ischemic stroke. For MMD patients with stoke, hemodynamic infarction type was the main type of ischemic stroke, and ventricular hemorrhage was the main type of hemorrhagic stroke. Age, Suzuki stage, diabetes mellitus and intracranial aneurysm were independent risk factors for stroke in young MMD patients.

Objective: To identify characteristic genes of rheumatoid arthritis （RA） by artificial neural network and to analyze role of immune cells in RA related microenvironment. Methods: GSE1919 and GSE77298 chips were from GEO database. Two chips were combined and batch corrected using R language to obtain a new data set, and difference was analyzed. Metascape enrichment analysis and GO and KEGG enrichment analysis were conducted for differential expressed genes （DEGs）. "randomForest" package in R software was used to screen characteristic genes of RA under random forest （RF） algorithm, and artificial neural network model was constructed according to gene score. Top 4 genes （HubGene） were extracted for subsequent analysis. Single sample gene set enrichment analysis （ssGSEA） was used to calculate abundance of immune cells in samples and carry out a series of correlation analysis. Results: Top 15 genes were selected as characteristic genes of RA through artificial neural network model: STAT1, RUNX3, AR, CDH11, LMO4, TIMP1, PLXNC1, CAP2, PRKAA2, VDR, SPP1, HCK, EPHB2, KCNAB1, ITGB7. STAT1, RUNX3 and CDH11 were up-regulated in RA synovial tissue, while AR was down-regulated in RA synovial tissue. Immune cell infiltration results showed that RA had the most significant correlation with activated CD4 T cells. Number of immune cells significantly related to RUNX3 was the largest. RUNX3 was significant positive correlated with activated B cells, activated CD4 T cells, activated CD8 T cells, central memory CD4+T cells, effector memory CD8 T cells, regulatory T cells, γδT cells and macrophages, while significant negative correlated with NK cells. Conclusion: Fifteen characteristic genes related to RA are identified through artificial neural network, among which STAT1, RUNX3, AR and CDH11 are top 4 genes. It emphasizes activation of CD4 T cells, regulatory T cells, γδT cells, macrophages, NK cells, activated B cells and other immune cells are important in pathogenesis of RA, providing new insights for diagnosis of RA and study of molecular mechanism of immune cells.

Aiming at the problems of multi-source heterogeneity of automotive industry chain resource information and the difficulty of establishing cross-platform interaction, this paper proposed a blockchain-based cross-domain permission delegation mode (BCPDM). Firstly, it combined blockchain technology with attribute-based access control (ABAC) model, and established a permission filtering function to avoid inter-platform permission conflicts. Secondly, it introduced a permission retraction mechanism to improve the flexibility of the model authorization and avoid the problem of information leakage that might be caused by prolonged authorization, aiming to solve the access authorization problem under the multidomain environment of complex automotive industry chain in a flexible, dynamic, efficient and trustworthy way. The security analysis and experimental results show that the proposed method can ensure the safe access of users and data and information interaction between platforms in the multi-domain environment of complex automotive industry chain, and the computational overhead is low. The method can meet the real-time requirements of automobile industry chain cooperative interaction, and provides a feasible solution for solving the access control problem in complex automobile industry chain.

Addressing the issues of dynamic complicated constraints and the lack of visualization in automatic guided vehicle(AGV) scheduling at automated container terminals, this paper utilized the AnyLogic platform to construct a computational experiment model of an automated container terminal within the conceptual framework of computational logistics. It proposed two aspects of improvement for the AGV scheduling strategies within the model. Firstly, it employed the ILOG CPLEX to the AnyLogic system to solve dynamic complicated combinatorial optimization problem. Secondly, it devised five problem-oriented customized AGV scheduling strategies based on computational logistics. Due to the inhe-rent limitations of the CPLEX solver, the model and experimental data primarily focused on the import containers of the automated container terminal. The computational experiments demonstrate that the customized sche-duling strategies effectively complement the limitations of the CPLEX and the AnyLogic. In comparison to the original system policies, the customized strategies can better realize the production scheduling of AGVs for specific loading and unloading needs, while meeting efficient scheduling requirements.

Objective To investigate the manifestation of non motor symptoms, specifically gastric emptying disorders, in early Parkinson's disease (PD) patients using gastrointestinal ultrasonography. Methods Thirty-two outpatients and inpatients diagnosed with early Parkinson's disease (Hoehn and Yahr stage IIII) with symptoms of gastric emptying disorders (including nausea, vomiting, early satiety, and postprandial bloating) (PD group) and 30 healthy participants undergoing physical examinations during the same period (control group) underwent gastrointestinal ultrasonography. Gastric motility parameters including antral contraction amplitude (ACA), antral contraction frequency (ACF), gastric motility index (GMI), gastric emptying rate (GER), gastric emptying time (GET), gastric wall thickening rate, and gastric peristaltic wave velocity were recorded and measured at different time points (0-120 min) after ingestion of the contrast agent. Results The values of ACA, ACF, GMI, and GER in the PD group were lower than those in the control group at each time point ( P < 0.01 P < 0.05 ) . Gastric emptying time was significantly longer in the PD group compared to the control group (P < 0.01) At 30 minutes, the gastric wall thickening rate and gastric peristaltic wave velocity in the PD group were lower than those in the control group (P < 0.01) . Conclusion Gastric emptying disorders in early Parkinson's disease patients can be effectively evaluated using gastrointestinal ultrasonography. [ABSTRACT FROM AUTHOR]
