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.

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. However, due to varying levels of information technology development across medical institutions, nursing decision support systems (NDSS) remain in a fragmented development stage. This article explores the current application status and existing shortcomings of NDSS based on EMR systems, aiming to provide reference for the design and improvement of NDSS in various levels of medical institutions.

Objective:To analyze the application value of metagenomic next-generation sequencing (mNGS) in the detection of pathogenic bacteria in brain abscesses.Methods:The data of patients with brain abscess in Tianjin Huanhu Hospital from January 2019 to December 2021 were retrospectively analyzed. All patients underwent stereotaxic abscess puncture and drainage. According to the different methods of pathogen detection, they were divided into bacterial culture group (bacterial culture only) and mNGS group (bacterial culture with mNGS). The clinical symptoms, abscess site, bacterial culture and mNGS results, antibiotic application protocol and prognosis of the patients were analyzed. The bacterial detection results of the two groups were analyzed, and the antibiotic application and prognosis were compared. χ 2 test, exact probability method and Mann Whitney test were used to compare the difference between the two groups. Results:A total of 43 patients with brain abscess were enrolled, including 21 cases in bacterial culture group and 22 cases in mNGS group. The positive rate of bacteria culture group was 42.9% (9/21), the positive rate of bacteria culture group was 45.5% (10/22), and the positive rate of mNGS detection was 100% (22/22). Only 3 cases in the bacterial culture group could have a clear bacterial source, while 17 cases in the mNGS group could have a clear bacterial source according to the bacterial results, showing a significant statistical difference between the two groups (χ 2=19.69, P<0.001). The return time of bacterial culture was 7.0 (4.0,7.0) days, and the average return time of mNGS was 1.5 (1.5,1.5) days, the difference of bacterial return time between the two groups was statistically significant ( Z=0.00, P<0.001). The cost of antibiotic use in bacterial culture group was 24.00 (5.60,31.00) thousands yuan, and the cost of antibiotic use in mNGS group was 12.00 (2.10, 20.00) thousands yuan, and there was significant statistical difference between them ( Z=5.22, P=0.026). Conclusions:MNGS can quickly and accurately identify the types and sources of brain abscess pathogens, guide the clinical application of antibiotics more targeted, reduce the cost of antibiotic use, and is an effective method for the detection of brain abscess pathogenic bacteria.

Objective:To investigate the clinical manifestations, pathogenesis,diagnosis and treatment of negative pressure hydrocephalus (NPH).Methods:A retrospective analysis was performed on the 5 patients with NPH admitted to the Department of Neurosurgery, Tianjin Huanhu Hospital from January 2019 to December 2021. All of the patients underwent lumbar puncture and ventricular puncture to test the pressure. Three patients underwent endoscopic third ventriculostomy (ETV), the outcome of the patients was observed.Results:The pressure of subarachnoid was not equal to intraventricular, and the pressure of intraventricular was negative. Cisternography showed cerebrospinal fluid circulation obstruction in all 5 cases. The symptoms of 1 patient were improved after external negative pressure drainage, 3 patients were improved after further ETV and 1 patient had pulmonary infection without further surgical treatment.Conclusion:With the obstruction of cerebrospinal fluid circulation, the pressure of lateral ventricle and subarachnoid is different, when the pressure of brain or subarachnoid drop, the ventricular expansion under the effect of pressure gradient, intraventricular pressure drop even for the negative pressure. CT cisternography provides strong evidence for the diagnosis of this disease. External ventricular drainage with negative pressure and ETV are effective treatment methods.
