BACKGROUND:With advancements in stem cell research,the therapeutic efficacy of adult stem cells such as endothelial progenitor cells and mesenchymal stem cells in atherosclerosis and complications arising from atherosclerosis and vascular stent implantation is gradually being recognized.Due to the limitations of intravenous infusion of adult stem cells,including poor targeting and low treatment efficiency,recent research has focused on surface modification of vascular stents to achieve localized aggregation and functional modulation of endothelial progenitor cells or mesenchymal stem cells. OBJECTIVE:To discuss the therapeutic progress of endothelial progenitor cells and mesenchymal stem cells in vascular stent-related diseases,summarize the research status of the design of vascular stents based on endothelial progenitor cells and mesenchymal stem cells. METHODS:Relevant literature was retrieved on CNKI,WanFang,PubMed,and Web of Science databases since their inception.The Chinese search terms were"endothelial injury,stenting,thrombosis,intimal hyperplasia,atherosclerosis,endothelial repair,endothelial progenitor cell,mesenchymal stem cell,vascular stent."English search terms were"endothelial injury,stenting,thrombosis,intimal hyperplasia,atherosclerosis,endothelial repair,endothelial regeneration,endothelial progenitor cell,mesenchymal stem cell,vascular stent,vascular scaffold."According to inclusion and exclusion criteria,127 articles were finally reviewed. RESULTS AND CONCLUSION:Endothelial progenitor cells and mesenchymal stem cells can treat atherosclerosis and complications of stent implantation through differentiation and paracrine effects,mainly by protecting endothelial cells,regulating the expression of inflammatory cells and cytokines,and modulating smooth muscle cell proliferation and phenotype.Mesenchymal stem cells may have adverse reactions such as thrombosis and vascular calcification in therapeutic applications,and using extracellular vesicles and co-administration with heparin for surface modification is a feasible solution.Currently,there is more research on stents based on endothelial progenitor cells,mainly focusing on recruitment,capture,proliferation,differentiation,and activity.Research on stents based on mesenchymal stem cell capture in the vascular field is relatively scarce,but exosome-loaded stents derived from mesenchymal stem cells have been found to have highly effective therapeutic efficacy.Additionally,some underlying diseases such as diabetes may affect the activity of adult stem cells,leading to the loss of effectiveness in stem cell-based stent designs.Therefore,in future stent designs,consideration should be given to the background diseases.

Guided by the theory of "kidney generates marrow"， the study elaborates the viewpoint that the route of Yin Heel Channel （阴跷脉） is consistent with the "kidney-marrow-brain" axis from the perspective of the circulation of the meridians and the relationship between the zang-fu organs. Accordingly， it is believed that disease of Yin Heel Channel and dysfunction of the "kidney-marrow-brain" axis are the core pathogenesis of children enuresis， and it is elaborated from the following three major aspects， firstly， insufficient kidney essence， dysfunction of the "kidney-marrow-brain" axis， secondly， disease of Yin Heel Channel and deficiency and cold in lower jiao， and thirdly， disease of Yin Heel Channel and loss of nourishment of Chong Vessel. It is proposed to use the mode of "firstly needle， secondly moxibustion， and lastly consolidation" to treat children enuresis. Needle is to adjust yin and yang， warm yang and tonify kidney， and wake up the brain and open the orifices. The acupoints in Yin Heel Channel such as Zhaohai （KI 6）， Jiaoxin （KI 8） and confluence points of the eight extraordinary vessels such as Waiguan （TE 5）， Zulinqi （GB 41） are used， together with Baihui （GV 20）， Yintang （EX-HN 3）， Guanyuan （CV 4）， Qixue （KI 13）， Dazhong （KI 4）. Moxibustion is to reinforce healthy qi and warm yang， bank up the root and consolidate the original qi by moxibustion at Shenque （CV 8）， Mingmen （GV 4）， and Xuanshu （GV 5）. Consolidation is to use acupoints application to consolidate the therapeutic effect， and Guanyuan （CV 4） & Pangguangshu （BL 28）， Qihai （CV 6） & Zhishi （BL 52）， and Shenque （CV 8） & Ciliao （BL 32） are commonly used as the three groups of acupoints to warm the kidney and stop collapse， regulate and tonify the qi and blood.

Objective To study and compare the oral microbiota and metabolites of children with Henoch Schonlein purpura(HSP)to identify specific microbiota and metabolites related to this disease and elucidate the pathogenesis of HSP.Methods Three groups of qualified subjects were included,including 20 in the HSP group,20 in the HSP nephritis(HSPN)group,and 20 in the control group.Perform high-throughput 16S rRNA sequencing and metabolic profiling of saliva from each group to analyze the correlation between differential microbiota and differ-ential metabolites.Results(1)Compared with the control group,there was a significant difference in richness and diversity in the HSPN group(P＜0.05).At the same time,there was no significant difference in richness and diver-sity in the HSP group(P＞0.05).Compared with the HSP group,the abundance,and diversity of the HSPN group were significantly increased(P＜0.05).At the genus level,the proportion of Streptococcus in each group is the high-est.Compared with the control group,there was no significant correlation between the HSP group and the genus of bacteria.In contrast,the HSPN group showed a significant increase in the genera of Pseudomonas and Parabacteroi-des(P＜0.05).Compared with the HSP group,the abundance of Pseudomonas and Parabacteroides in the HSPN group was significantly increased(P＜0.05).(2)Compared with the control group,the HSPN group had 12 differen-tial metabolites involving nine metabolic pathways,such as phenylalanine metabolism;There was no significant dif-ference in metabolites and no metabolic pathway in the HSP group.Compared with the HSP group,the HSPN group has 15 differential metabolites involving nine metabolic pathways,such as phenylalanine metabolism.(3)In the HSPN and control groups,Pseudomonas and Parabacteroides negatively correlated with Phenylalanine metabolic pathway products.In the HSPN and HSP groups,Pseudomonas,Parabacteroides,and Phenylalanine metabolic path-way products were negatively correlated.The metabolites involved in phenylalanine metabolism in the oral cavity are 2-hydroxycinnamic acid,Phenylpyruvic acid,and N-acetyl-L-phenylalanine.Conclusion There is a significant dif-ference between HSPN and HSP children and healthy children.Streptococcus,Pseudomonas,and Parabacteroides may be one of the trigger factors of HSPN,and Phenylalanine metabolism may be one of the pathways in the patho-genesis of HSPN.Children with HSPN have a more pronounced imbalance in oral microbiota and greater differences in metabolic products than children with HSP.

With the continuous improvement of medical information and intelligence, multi-modal data fusion technology is increasingly widely used in the medical field. Multi-modal data not only has a large quantity, but also has rich information content, which can provide strong support for clinical nursing decision-making. However, due to the uneven level of informatization and intelligence development among medical institutions, the development and application of nursing decision support system is still in a fragmented state. Based on this, this study explores in depth the current application status and challenges faced by multi-modal data fusion in nursing decision support systems, with the aim of providing reference for the design and improvement of nursing decision support system at all levels of medical institutions in the future.

With the continuous advancement of information technology, electronic medical records (EMR) have accumulated vast amounts of clinical data, which can assist nursing staff in making clinical decisions, thereby improving the quality of care, enhancing work efficiency, and promoting patient safety.

OBJECTIVES: To investigate the role of Holliday cross-recognition protein (HJURP) in tumorigenesis, progression, and immunotherapy responses. METHODS: Bioinformatics approaches were used to analyze the expression level of HJURP in various cancers and its association with prognosis, clinical stage, and immune cell infiltration using TCGA, GTEx, SangerBox and TIMER 2.0 databases. LinkedOmics database was employed to investigate HJURP-related genes and their potential functions in kidney renal clear cell carcinoma (KIRC). The expression of HJURP in KIRC samples was examined with immunohistochemistry, Western blotting and qRT-PCR, and the effect of HJURP silencing on cell proliferation and migration was tested in cultured KIRC cells. RESULTS: HJURP was highly expressed in 26 cancers with negative correlations with the patients' survival outcomes in 5 cancers including KIRC (P<0.05). HJURP expression levels was strongly correlated with clinical stages and immune cell infiltration in the tumors. In KIRC, HJURP expression was significantly elevated (P<0.0001) and showed a positive correlation with TNM stage (P<0.05), overall stage (P<0.01) and immune cell infiltration. Gene Ontology (GO) functional analysis showed that HJURP is predominantly enriched in biological processes such as biological regulation and metabolic processes. Concerning cellular components, HJURP is primarily localized to the cell membrane and nucleus. In terms of molecular functions, it is chiefly enriched in activities related to protein binding and ion binding. HJURP was highly expressed in both clinical KIRC tissues and KIRC cell lines (P<0.001). In cultured KIRC cells, silencing of HJURP significantly inhibited cell proliferation and migration abilities. CONCLUSIONS HJURP may serves as an indicator of prognosis and immunotherapy response of KIRC, and its high expression enhances malignant behaviors of KIRC cells.

Color is an important indicator for evaluating the ornamental traits of horticultural plants, and plant pigments is a key factor affecting the color phenotype of plants. Plant pigments and their metabolites play important roles in color formation of ornamental organs, regulation of plant growth and development, and response to adversity stress. It has therefore became a hot topic in the field of plant research. Virus-induced gene silencing (VIGS) is a vital genomics tool that specifically reduces host endogenous gene expression utilizing plant homology-dependent defense mechanisms. In addition, VIGS enables characterization of gene function by rapidly inducing the gene-silencing phenotypes in plants. It provides an efficient and feasible alternative for verifying gene function in plant species lacking genetic transformation systems. This paper reviews the current status of the application of VIGS technology in the biosynthesis, degradation and regulatory mechanisms of plant pigments. Moreover, this review discusses the potential and future prospects of VIGS technology in exploring the regulatory mechanisms of plant pigments, with the aim to further our understandings of the metabolic processes and regulatory mechanisms of different plant pigments as well as improving plant color traits.
