Hepatic stellate cells (HSCs) are the primary fibrogenic cells in the liver, and their activation plays a crucial role in the development and progression of hepatic fibrosis. Here, we report that retinoid X receptor-alpha (RXRα), a unique member of the nuclear receptor superfamily, is a key modulator of HSC activation and liver fibrosis. RXRα exerts its effects by modulating calcium/calmodulin-dependent protein kinase kinase β (CaMKKβ)-mediated activation of AMP-activated protein kinase-alpha (AMPKα). In addition, we demonstrate that K-80003, which binds RXRα by a unique mechanism, effectively suppresses HSC activation, proliferation, and migration, thereby inhibiting liver fibrosis in the CCl₄ and amylin liver NASH (AMLN) diet animal models. The effect is mediated by AMPKα activation, promoting mitophagy in HSCs. Mechanistically, K-80003 activates AMPKα by inducing RXRα to form condensates with CaMKKβ and AMPKα via a two-phase process. The formation of RXRα condensates is driven by its N-terminal intrinsic disorder region and requires phosphorylation by CaMKKβ. Our results reveal a crucial role of RXRα in liver fibrosis regulation through modulating mitochondrial activities in HSCs. Furthermore, they suggest that K-80003 and related RXRα modulators hold promise as therapeutic agents for fibrosis-related diseases.

Alzheimer disease(AD)is a neurodegenerative disorder characterized by the abnormal deposition of amyloid β-protein(Aβ).Inflammation plays a significant role in promoting this abnormal deposition.Toll-like receptor 4(TLR4)is recognized as a"primary regulator"of the inflammatory response,facilitating the activation of microglia and interacting with various pathways,including nuclear factor-κB and nucleotide-binding oligomerization domain-like recep-tor protein 3.This interaction can lead to an inflammatory cascade that accelerates the progression of AD.Numerous pro-spective studies have demonstrated that traditional Chinese medicine can modulate the TLR4 signaling pathway,effective-ly addressing both the onset and progression of AD.However,a comprehensive review of how Chinese medicine regulates this pathway in the treatment of AD is currently lacking.Therefore,this paper aims to detail the latest findings related to TLR4 in the prevention and treatment of AD,drawing from recent literature.It will explore the mediation of traditional Chinese medicine,preserving its essence,and provide references and a basis for clinical practices aimed at preventing and treating AD.

Insulin is an important protein hormone that participates in multiple metabolic pathways.Biosynthetic insulin has been widely used in the treatment of type 1 and type 2 diabetes.Currently,the number of reported cases of insulin overdose both at home and abroad is gradually increasing,and insulin homicide is no longer a means of"committing murder without leaving a trace".At present,there are no systematic protocols for the identification of insulin overdose in the field of forensic medi-cine in China.This article introduces the causes,toxicological characteristics,forensic examination,labo-ratory testing methods and indicator reference of insulin overdose.Based on the identification practice and research results and referring to relevant studies on insulin overdose at home and abroad,this pa-per aims to provide recommendations and references for the formulation of forensic identification guide-lines for insulin overdose cases.

Alzheimer disease(AD)is a progressive neurodegenerative disorder characterized by cognitive dysfunction and declining learning and memory abilities,significantly impacting daily lives and behavioral capacities of the patients.The mitogen-activated protein kinase(MAPK)signaling pathway,primarily composed of extracellular signal-regulated kinase,p38 MAPK,and c-Jun N-terminal kinase.Mounting evidence suggests that the MAPK signaling path-way is intimately linked to the pathogenesis of AD,providing crucial insights into the disease's progression.In recent years,traditional Chinese medicine(TCM)has demonstrated promising potential in treating AD,with its advantages of personalized therapy and multi-target regulation garnering increasing research attention.This study aims to review the ex-perimental research landscape of TCM interventions targeting the MAPK signaling pathway for the prevention and treat-ment of AD over the past five years.The findings reveal that effective compounds and herbal formulas in TCM,such as isorhamnetin,nobiletin,parthenolide,Glehnia littoralis,Ishige okamurae,shikonin,artemisinin,kaempferol,myrice-tin,and Tripterygium glycosides,can alleviate AD symptoms by modulating the MAPK signaling pathway.These interven-tions mitigate Aβ-induced neuronal damage,reduce Tau protein hyperphosphorylation,and suppress neuroinflammatory responses.The objective of this review is to provide a scientific and theoretical reference for the clinical prevention and treatment of AD and to inform the development of novel therapeutic agents.

Alzheimer's disease （AD） is a neurodegenerative disease often characterized by cognitive impairment in clinical practice. The main pathogenesis includes β amyloid protein （Aβ） excessive deposition， neuroinflammatory response， Tau protein hyperphosphorylation， and other factors， and currently only a few chemical drugs have been approved for clinical treatment of AD. The mechanism of action is relatively single， so it is imperative to find new treatment strategies. Traditional Chinese medicine theory believes that the loss of nourishment in the brain and marrow， as well as the loss of vital energy， is the internal mechanisms underlying the occurrence and development of AD， which runs through the entire treatment process. The pathogenesis of AD is closely related to the inflammasome signaling pathway of nucleotide binding oligomerization domain-like receptor protein 3 （NLRP3）. Activating the NLRP3 signaling pathway increases neuroinflammatory response， intervenes in microglial polarization， and regulates Aβ sedimentation， cellular autophagy， brain homeostasis， etc. This article takes the NLRP3 signaling pathway as the starting point to sort out and summarize the upstream and downstream targets under the AD mechanism in the past five years， as well as the research on the NLRP3 signal pathway targets with the participation of the relevant traditional Chinese medicine compounds， such as Danggui Shaoyaosan， modified Shuyu Wan， Qingxin Kaiqiao prescription， Kaixin San， Jiedu Yizhi prescription， and modified Buwang San， traditional Chinese medicine monomer extracts， such as silibinin， Lycium barbarum polysaccharides， liquiritigenin， salidroside， baicalin， cinnamaldehyde， betaine， acacetin， and Hericium erinaceus， and acupuncture and moxibustion. It also reviews the latest achievements in the prevention and treatment of AD. This study provides ideas and directions for in-depth research on the prevention and treatment of cognitive dysfunction related diseases with traditional Chinese medicine.

ObjectiveThis study aimed to evaluate the clinical efficacy of Ruyi Zhenbaowan（RYZBW）in the treatment of initial and early knee osteoarthritis （KOA） through a prospective multicenter，randomized，double-blind，and placebo-parallel controlled trial. MethodFrom October 13^th， 2021 to December 25^th， 2021， 240 KOA subjects meeting the acceptance criteria were enrolled in 15 sub-centers including Wangjing Hospital， Chinese Academy of Chinese Medical Sciences， and they were randomly divided into observation group and control group， with 120 cases in each group. The intervention measures for the observation group were RYZBW + health education， and the intervention measures for the control group were RYZBW placebo + health education. The intervention period in both groups was four weeks， and they were followed up for four weeks after the intervention. The primary outcome measure was the total score of Western Ontario and McMaster University Osteoarthritis Index score （WOMAC score）， and the secondary outcome measures were the response rate of visual scale （VAS） pain score， WOMAC sub item scores （joint pain， joint stiffness， and joint function）， quality of life （SF-12） score， and traditional Chinese medicine （TCM） syndrome score. Result（1） Efficacy evaluation. The marginal model results showed that the observation group was better than the control group in improving the WOMAC total score and WOMAC pain score in the treatment of KOA with RYZBW， and the difference was statistically significant （P<0.05）. There was no significant difference between the two groups in improving VAS score response rate， WOMAC function score， WOMAC stiffness score， SF12-PCS （quality of life-physical health） score， SF12-MCS （quality of life-mental health） score， and TCM syndrome score. （2） Subgroup analysis. ① In terms of VAS score response rate， the response rate of the observation group was higher than that of the control group for subjects with baseline VAS score of （4， 5］， and the difference was statistically significant （P<0.05）. ② In terms of TCM syndrome score， for subjects aged ［56， 60］ and ［61， 65］， the decrease in total TCM syndrome score in the observation group was better than that in the control group， and the difference was statistically significant （P<0.05）. ConclusionTibetan medicine RYZBW has good clinical efficacy in improving WOMAC total score， VAS score response rate， WOMAC pain score， WOMAC function score， and TCM syndrome score for patients with initial and early KOA， which can fill the lack of Tibetan medicine RYZBW in the treatment of KOA and make a demonstration study for the inheritance and development of ethnic medicine.
