Objective: To prepare the erythrocyte-liposome drug delivery system to enhance the therapeutic effect of drugs on tumors and inhibit tumor metastasis. Methods: This study prepared and characterized paclitaxel (PTX)-plerixafor (AMD3100) liposomes (Lips), developed the erythrocyte-liposome drug delivery system, and evaluated its targeting efficiency and therapeutic efficacy through a series of in vitro cellular and in vivo animal experiments. Results: The particle size of PTX-AMD-Lips was (186.4±0.83) nm. Drug encapsulation efficiency of PTX-AMD-Lips was (75.50±5.27)% for PTX and (88.31±2.45)% for AMD. The Binding efficiency between RBC and liposomes in the drug delivery system was (69.93±2.55)%. Vitro cellular experiments revealed that PTX-AMD-Lips significantly inhibited tumor cell migration. In vivo animal experiments, the erythrocyte-liposome drug delivery system significantly increased drug accumulation in the lungs. At the experimental endpoint, the quantitative fluorescence signal of tumor size measured (4.04±0.44)×10 for the PTX-Lips group, and (5.14±3.40)×10 for the RBC-PTX-AMD-Lips group. Conclusion: The erythrocyte-liposome drug delivery system could enhance the lung-specific targeting capability of liposomes, kill tumor cells and suppress further metastasis effectively.

Objective: To enhance the ability of nanoparticles to target and bind tumor cells by constructing a neutrophil hitchhiking system based on hyaluronic acid (HA)-modified dual-drug loaded lipid nanoparticles. Methods: Lipid nanoparticles (LNPs) were prepared using microfluidic technology, and the nitrogen/phosphate (N/P) ratio, flow rate ratio, and drug-to-lipid ratio were optimized. HA-modified LNPs (HA-LNPs) were prepared and characterized. The interaction between the nanoparticles and tumor cells was evaluated through in vitro cell experiments. Results: The optimal preparation conditions for LNPs are N/P=8, flow rate ratio=5, and drug-to-lipid ratio=1∶30 (w∶w). HA-LNPs has a particle size of (177.28±2.41) nm, a polydispersity index (PDI) of 0.198±0.10, and an siRNA encapsulation efficiency of (91.37±0.47)%. The optimal binding rate with neutrophils was (98.64±2.34)%. Conclusion: An HA-modified dual-drug loaded lipid nanoparticle-neutrophil hitchhiking system was successfully constructed, enhancing the synergistic anti-tumor activity of the nanomedicine and the uptake of nanoparticles by tumor cells, providing a novel delivery strategy for targeted therapy of bone marrow tumors.

Cardiovascular diseases pose a significant threat to the public health and healthcare systems in Chi-na.Their pathogenesis is complex and not yet fully elucidated.Increasing evidence suggests that the gut microbiota plays a crucial role in maintaining health and modulating disease progression.Dysbiosis of the gut microbiota has emerged as a key contributor to the development of cardiovascular diseases and has become a prominent focus of current biomedical re-search.Fecal microbiota transplantation,a direct and effective method for restoring gut microbial balance,has been ap-plied in clinical practice with continuously expanding indications,demonstrating the potential to become a novel therapeu-tic strategy for the prevention and treatment of cardiovascular diseases.This article reviews the technology of fecal microbi-ota transplantation,with a particular focus on its applications in major cardiovascular diseases,including atherosclerosis,myocardial infarction,heart failure,hypertension,atrial fibrillation,and myocarditis.It also outlines the potential mecha-nisms through which fecal microbiota transplantation may exert its therapeutic effects,aiming to provide a reference for clinical strategies in the prevention and management of cardiovascular diseases.

Under the background of the in-depth advancement of the Healthy China strategy,as the basic unit of health education,how to activate the health education function of the family has become an important issue in current health governance.From the perspective of empowerment theory,this article sorts out the basic logic of health education carried out by families through case studies,systematically analyzes the functional positioning of the empowerment subjects(dominant type,executive type,and supplementary type),and reveals how these empowerment subjects support and promote the implementation of family health education through formal and informal empowerment methods.And explore the empowerment mechanism of family health education from"empowerment conditions-empowerment process-empowerment results",and deeply analyze the influence of the combination mode of empowerment subjects on the empowerment mechanism.The research suggests that at the institutional level,a collaborative mechanism among three types of empowerment subjects should be established.At the practical level,it is necessary to ensure the implementation of empowerment,stimulate the initiative within families,and promote an optimized path for the precise matching of health education content with the differentiated needs of families.The research provides new perspectives and strategies for health education at the family level,which is of great theoretical and practical significance for promoting the practice of health education.

Aim To investigate the effect of Huangqi injection(HI)and Huangqi oral solution(HO)on cisplatin-induced nephrotoxicity(CIN)based on un-targeted metabolomics technology and the underlying mechanisms.Methods Sprague Dawley(SD)rats were randomly divided into the blank group,cisplatin(CDDP)model group,HI treatment group,and HO treatment group,then the CIN model was built with low dose multiple intraperitoneal injections of CDDP.Pre-liminary evaluation of the renal protective efficacy of HI and HO was performed by measuring serum creatinine(Scr),blood urea nitrogen(BUN),and organ indi-ces.Further screening and identification of potential biomarkers(PBs)related to CIN and HI/HO pharma-cological effects were attained through metabolomics studies of renal tissues,and pathway enrichment analy-sis was conducted.Results HI and HO significantly restored the abnormal increase in renal function indica-tors and abnormal decrease in organ indices caused by CDDP,as well as significantly improved the abnormal renal metabolic profile induced by CDDP,indicating that both HI and HO had good alleviating effects on CIN.HI significantly reversed 47 out of 54 CIN related PBs,mainly involving metabolic pathways such as glycerophospholipid metabolism,tryptophan metabo-lism,pantothenate and CoA biosynthesis;HO signifi-cantly reversed 18 out of 54 CIN related PBs,mainly involving metabolic pathways such as taurine and hypo-taurine metabolism,ascorbate and aldarate metabo-lism,pentose and glucuronate interconversions.Con-clusions Both HI and HO have significant alleviating effects on CIN.In the short term,HI salleviating effect is superior to that of HO.Overall,the mechanisms by which both alleviate CIN are mainly related to regula-ting lipid metabolism,amino acid metabolism.
