Acute lung injury (ALI) has been a kind of acute and severe disease that is mainly characterized by systemic uncontrolled inflammatory response to the production of huge amounts of reactive oxygen species (ROS) in the lung tissue. Given the critical role of ROS in ALI, a Fe₃O₄ loaded bovine serum albumin (BSA) nanocluster (BF) was developed to act as a nanomedicine for the treatment of ALI. Combining with NIR irradiation, it exhibited excellent ROS scavenging capacity. Significantly, it also displayed the excellent antioxidant and anti-inflammatory functions for lipopolysaccharides (LPS) induced macrophages (RAW264.7), and Sprague Dawley rats via lowering intracellular ROS levels, reducing inflammatory factors expression levels, inducing macrophage M2 polarization, inhibiting NF-κB signaling pathway, increasing CD4⁺/CD8⁺ T cell ratios, as well as upregulating HSP70 and CD31 expression levels to reprogram redox homeostasis, reduce systemic inflammation, activate immunoregulation, and accelerate lung tissue repair, finally achieving the synergistic enhancement of ALI immunotherapy. It finally provides an effective therapeutic strategy of BF + NIR for the management of inflammation related diseases.

BACKGROUND:The incidence of inflammatory bowel disease has been steadily rising,accompanied by a lack of definitive therapeutic strategies.Recent research endeavors have illuminated the promising potential of mesenchymal stem cells in mitigating the symptoms of inflammatory bowel disease,offering a glimmer of hope for afflicted patients.OBJECTIVE:To review the mechanisms of action of mesenchymal stem cells derived from various sources in the management of inflammatory bowel disease,aiming to provide insights for future research endeavors.METHODS:Utilizing the keywords"mesenchymal stem cells,MSCs,exosomes,extracellular vesicles,EVs,inflammatory bowel disease,IBD,ulcerative colitis,UC,Crohn's disease,CD"in English and their Chinese equivalents in CNKI and PubMed databases,a total of 89 eligible articles were selected for this review.RESULTS AND CONCLUSION:Currently,six types of mesenchymal stem cells are being explored for inflammatory bowel disease therapy:bone marrow-derived mesenchymal stem cells,adipose tissue-derived mesenchymal stem cells,perinatal tissue-derived mesenchymal stem cells,induced pluripotent stem cell-derived mesenchymal stem cells,embryonic stem cell-derived mesenchymal stem cells,and gingival mesenchymal stem cells.Five administration routes have been adopted,with intravenous and intraperitoneal injections being the most prevalent,followed by local,mesenteric,and intra rectal injections.Their therapeutic mechanisms encompass differentiation,regeneration,anti-inflammatory effects,immune modulation,neuroprotection,antioxidant stress response,homing,modulation of gut microbiota,autophagy,ferroptosis,and endoplasmic reticulum stress.While sharing functional similarities,mesenchymal stem cells from different sources exhibit unique characteristics that confer them with distinct advantages and therapeutic potentials.Nevertheless,research into the specific properties of these mesenchymal stem cells remains limited,necessitating deeper exploration of their nuanced differences to optimize their therapeutic efficacy in inflammatory bowel disease.Additionally,the clinical safety of mesenchymal stem cells-based therapies warrants further observation and evaluation.

Objective The purpose of this research is to use modern statistical methods,to analyze the rules of cointment by Prof.Yang Zhimin treating yang deficiency and fatigue state patients,to increase the pertinence and to improve the clinical efficacy.Methods This paper analyzed 62 cases of Prof.Yang Zhimin in the treatment of the patients with yang deficiency and fatigue state from October 2010 to January 2013.The analyses were frequency analysis and association rules.Results Among the patients with yang-deficiency and fatigue,193 Chinese medicine were used.The monkshood was the highest frequency.Dampness-transforming medicine accounts for about 22.2％ in the top 36 frequency of medicine.Based on analyzing association rules,we found that the compatibility of medicine which were used more frequently came from Sini decoction,Danggui Sini decoction and Jinkui Shenqi pills,such as "monkshood and dried ginger","monkshood and roasted liquorice","dried ginger and roasted liquorice","monkshood and angelica","monkshood and comel","monkshood and prepared rehmannia root" and "monkshood and yam".Futhermore,we found two new core prescription.One was Qian Yang Dan combined with Sini decoction consist of "monkshood,roasted liquorice,dried ginger,fructus amomi".The other one was Tu Si Jian consist of "yam,semen cuscutae,angelica,roasted liquorice".Conclusions "Invigorating spleen and kidney","warming yang and dissipating dampness" and "hiding yang and Seeking Yang in Yin" are the habits and rules of the ointment medication by Prof.Yang Zhimin treatingyang deficiency and fatigue state patients.
