The present paper is aimed to observe the lateral attachment of the renal fascia (RF) in vivo with multidetector computed tomography (MDCT) scanning, and to discuss its diagnostic value. 121 healthy adults were adopted into this experiment. All images were obtained with MDCT and double phase enhancement scanning. Then we observed the lateral attachment of RF. In addition, we mad a fresh body specimen as anatomical basis. The study found that above the renal hilar plane (RHP), the anterior renal fascia laterally fused with the peritoneum of the liver on the right and the peritoneum of the spleen on the left,and the posterior renal fascia fused with the subdiaphragmatic fascia. The lateral attachment of the RF at the RHP and the lower renal pole(LRP)is divided into three types. The RF in Type I is about 47.9% (58/121) at the left RHP, while about 33.9% (41/121) at the right RHP. At the LRP of the kidney is about 55.3% (67/121) on the left, and about 42.1% (51/121) on the right. The RF in Type I is about 38.8% (47/121) on the left side at the RHP, about 26.4% (32/121) on the right side. At the LRP, left side about 27.3% (33/121), right side about 13.3%(16/121). The RF in Type III at the RHP is 13.3% (16/121) on the left side, and on the right side is about 39.7% (48/121). At the LRP, it is about 17.4% (21/121) on the left side, and about 44.6% (54/121) on the right side. MDCT can display the lateral attachment of the RF better as well as the outside connection of the retroperitoneal space.

This paper reviews the current situation of dementia care in the emergency setting at home and abroad, and compares the contents of person-centred care practices, such as identifying and assessing dementia patients, changing caregivers ′ attitudes, creating a good emergency environment, and mastering and providing effective nurse-patient communication, with the aim of providing a reference basis for developing a standardised care plan for dementia patients in the emergency setting, with a view to providing more scientific and efficient emergency care for dementia patients.

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.
