Objective:To conduct bioinformatics analysis by detecting and screening differentially expressed miRNAs in urine exosomes of subjects with damp heat IgA nephropathy, non damp heat IgA nephropathy, and healthy individuals; To explore the role of miRNAs in renal tubulointerstitial fibrosis.Methods:A cross-sectional study was conducted to select 40 subjects with primary IgA nephropathy diagnosed by renal biopsy in the Department of Traditional Chinese Medicine, Zhujiang Hospital of Southern Medical University from November 2021 to February 2023, who were divided into damp-heat group and non-damp-heat group according to TCM constitution, with 20 cases in each group; 10 healthy subjects were also recruited for control observation.High-speed centrifugation and Illumina high-throughput sequencing technology were used to isolate and detect the expression of miRNA in urine exosomes from three groups of people, and their differential expression profiles were constructed. Bioinformatics analysis was performed on differentially expressed genes to determine the main biological functions of differentially expressed miRNAs and the signaling pathways they may participate in.Results:Compared with the non-damp heat group, there were 231 miRNAs with abnormal expression in the urine exosomes of the damp heat group, including 119 up-regulated and 112 down-regulated. Through GO enrichment and KEGG analysis, differentially expressed miRNAs may participate in the occurrence and development of renal tubulointerstitial fibrosis through MAPK signaling pathway, PI3K Akt signaling pathway, Hippo signaling pathway, Ras signaling pathway, Wnt signaling pathway, mTOR signaling pathway, etc., involving biological processes such as cell proliferation, apoptosis, cell deformation (EMT), migration and invasion, and tissue and organ fibrosis. MiR-29c-3p expression levels in the urinary exosome miRNA expression profiles of subjects in the three groups were lower in the damp-heat group, but higher in the non-damp-heat group versus the healthy control group, of which, the damp-heat group was lower than the non-damp-heat group versus the healthy control group ( P<0.01); there was no significant difference between the healthy control group and the non-damp-heat group ( P>0.05）. Conclusion:The expression profile of miRNAs in the urine exosomes of subjects with damp heat IgA nephropathy showed significant changes,that the significant down-regulation of miR-29c-3p may be a key factor in exacerbating tubulointerstitial fibrosis in IgA nephropathy.

The operating room was the core department of a hospital,and its operational efficiency had a significant impact on the high-quality development of a hospital.An analysis has revealed that low efficiency and irrational allocation in the operating room were mainly due to the lack of operational regulations and norms,the unreasonable arrangement of surgical specialties,and the unbalanced allocation of supporting resources.To address these issues,the First Affiliated Hospital of Zhengzhou University has taken into account the overall allocation of resources for the central operating room and the central operating room,and formulated strategies to improve operational efficiency,including adjusting the operational mechanism,optimizing the structure of surgical specialties,and providing corresponding supporting resources.Based on the adjustment of surgical structure,the implementation effect of the program was measured and evaluated,which provided practical strategies for optimizing operating room efficiency in hospitals.

The increasing operating pressure of large public hospitals has forced hospitals to focus on opening up income sources and reducing expenditure.The purchase and maintenance of medical equipment is one of the important economic activities of hospi-tals.However,there are problems in large public hospitals,such as the argumentation for equipment acquisition ignoring evaluation of operational efficiency,the costing model that leads to a lack of willingness of departments to purchase equipment,and the lack of standard processes and systems for renting medical equipment among departments.Based on this,it explores the establishment of a medical equipment sharing operation mechanism in large public hospitals,promotes the improvement of the efficiency of medical equipment use in large public hospitals by establishing a medical equipment sharing center,standardizing the purchase of shared equipment,entering shared equipment information,setting up shared equipment leasing specifications,and clarifying the equipment return process and maintenance,so as to effectively control hospital operating costs,and help the high-quality development of public hospitals.

ObjectiveTo observe the rule of functional reorganization in stroke patients during early recovery. MethodsFrom April, 2023 to April, 2024, 20 patients with serious left hemiplegia for right cerebral infarction of two to four weeks were included as experimental group, from Beijing Rehabilitation Hospital Affiliated to Capital Medical University; meanwhile, 20 healthy subjects were included as control group. All the subjects finished a block designed left elbow flexing task, and were measured with functional near-infrared spectroscopy. The control group finished the test once; and the experimental group finished the test once per two weeks, for five times, and laterality indexes were calculated; they were also assessed with Fugl-Meyer Assessment-Upper Extremity (FMA-UE) before each test. ResultsThe score of FMA-UE increased time by time (P < 0.05). For the experimental group, laterality index showed that the activation shifted from right dominance to balance in the whole brain, primary motor cortex and supplementary motor area; and it shifted from balance to right dominance in dorsolateral prefrontal cortex, and form right dominance to left dominance in premotor cortex. ConclusionAt the early recovery stage of stroke patients, the upper limb motor function is gradually improving, with the activation in most motor cortex shifting from affected hemisphere dominance to bilateral hemisphere balance; however, the activation may become affected or unaffected dominance in some brain areas.
