Myocardial ischemia-reperfusion injury （MIRI） is one of the major complications of cardiovascular diseases in recent years， seriously threatening the life and health of patients. In recent years， although significant progress has been made in modern medical research on MIRI， due to its complex pathogenesis， adverse drug reactions， and high postoperative risks， there is an urgent need for safer and more effective therapeutic drugs. The pathological effects of MIRI involve inflammatory responses， oxidative stress， apoptosis， and other mechanisms， while Chinese medicine polysaccharide compounds exhibit pharmacological effects such as anti-inflammation， antioxidation， and anti-apoptosis， which are of great significance for improving MIRI. Numerous studies have found that Chinese medicine polysaccharide compounds mainly exert their effects by activating signal pathways such as nerve regenerative factor-1/epidermal growth factor receptor （NRG-1/ErbB）， phosphatidylinositol-3-kinase/protein kinase B （PI3K/Akt）， nuclear factor E₂-related factor 2/heme oxygenase-1 （Nrf2/HO-1）， adenosine 5ʹ-monophosphate-activated protein kinase/silent information regulator 1/peroxisome proliferators-activated receptor γ coactivator lα （AMPK/SIRT1/PGC1α）， Ras homologous gene/Rho kinase （Rho/ROCK）， glycogen synthase kinase 3 （GSK-3）， and P38 mitogen-activated protein kinase （p38-MAPK）， thereby playing a role in improving MIRI. This paper， based on an extensive review of relevant literature in China and abroad， systematically summarizes the latest research findings on the use of Chinese medicine polysaccharide compounds in the treatment of MIRI， analyzes the mechanisms by which these compounds improve MIRI， and explores new therapeutic directions based on the joint investigation of signaling pathways and metabolomics. The paper emphasizes the importance of interdisciplinary cooperation in promoting the development of new drugs， aiming to provide valuable references for the basic research and clinical application of Chinese medicine polysaccharide compounds， ultimately benefiting the majority of cardiovascular disease patients.

Cerebral ischemia-reperfusion injury （CIRI）， a common cerebrovascular disease damage， has garnered increasing attention in the treatment of acute ischemic stroke. Restoration of blood flow and reperfusion to ischemic brain tissue is the key to treatment， while this process often triggers a variety of complex pathophysiological responses， such as oxidative stress， apoptosis， inflammation， mitochondrial dysfunction， angiogenic abnormalities， and disruption of the blood-brain barrier. These responses not only impede the recovery of neurological functions but also may lead to damage or even death of nerve cells， seriously affecting the neurological function and quality of survival of patients. As an important transcription factor， nuclear factor E₂-related factor 2 （Nrf2） has the pharmacological effect of alleviating CIRI by regulating antioxidant， anti-apoptosis， anti-inflammation， mitochondrial function， angiogenesis， and blood-brain barrier pathways. This reveals the potential mechanism of traditional Chinese medicine （TCM） in intervening in CIRI and shows the potential of Nrf2 as a new pathway for dealing with ischemia stroke. This paper comprehensively analyzes the effects and mechanisms of active components and compound prescription of TCM in treating CIRI by modulating the Nrf2 signaling pathway， while pointing out the shortcomings of available studies and proposing a multidimensional exploration. This review aims to provide patients with more comprehensive， safe， and effective therapeutic regimens and improve the quality of survival and prognosis of patients. In addition， in-depth research on TCM should be promoted to reveal the potential mechanism for treating CIRI， providing new ideas and directions for the development of novel therapeutic drugs and methods.

Objective To compare the differences in the average transaction costs per-referral patients under different models of Integrated Delivery Systems(IDS).Methods Using a typical case sampling method,it selected referred patients from three IDS models:the county medical alliance in D City(Qinghai Province),the urban medical consortium in J District(Zhengzhou City,Henan Province),and the health management coalition in N County(Shandong Province).Structured questionnaires collected demographics,average transaction costs per-referral and cost perceptions.t-tests and ANOVA assessed cost differences;generalized linear regression identified influencing factors.Results Among 915 patients,the average transaction costs per-referral were 1 035.05 yuan(county alliance),195.31 yuan(urban consortium),and 700.97 yuan(health management coalition),with statistically significant differences(P＜0.05).The urban consortium exhibited lower time costs and specialized input costs.Key influencing factors included older age(county alliance),education level,employment status,and referral travel time(urban consortium),as well as urban-rural disparities(health management coalition).Patients'cost perceptions significantly differed across models(P＜0.05).Conclusion The urban medical consortium demonstrated the lowest patient the average transaction costs,highlighting its institutional advantage in minimizing financial burdens.

Chronic glomerulonephritis （CGN） is a common clinical chronic glomerular disease caused by autoimmune reaction， the pathogenesis of which is complex and has not been fully elucidated. There is no specific treatment method in modern medicine. The establishment of an animal model of CGN in accordance with its characteristics in western medicine and traditional Chinese medicine will help to reveal the pathogenesis of CGN， rate drugs， and improve the treatment plan. Based on the clinical diagnostic criteria of CGN， the paper establishes the syndrome differentiation criteria of CGN for Chinese and western medicine. Through summarizing the literature on animal models of CGN and making a further analysis， it is found that the CGN models are mainly modeled using rats with the methods of single-factor induction or two-factor induction， and the main manifestation of the disease characteristics is nephritis-related symptoms. The single-factor-induced or two-factor-induced CGN rat models have a high fitting degree with the clinical characteristics in western medicine， but the fitting degree is insufficient with the clinical characteristics in traditional Chinese medicine. In addition， the CGN models with syndromes of traditional Chinese medicine are dominated by Qi deficiency in the spleen and kidney and Qi deficiency in the lung and kidney， while models for Yang deficiency in the spleen and kidney， Yin deficiency in the liver and kidney， and deficiency of both Qi and Yin are slightly insufficient. Therefore， it is important to prepare a new and improved animal model of CGN， so that a preclinical model can be provided for the exploration of the pathogenesis of CGN in western medicine and traditional Chinese medicine and its therapeutic research.

Parkinson's disease is the second most common neurodegenerative disease in middle-aged and elderly people.It is characterized by a long disease course and complex treatment process,introducing great challenges to society.Behavioral changes in animal models of Parkinson's disease can intuitively reflect the modeling situation of experimental animals and the effects of drug interventions.Therefore,selecting standardized animal models and appropriate behavioral assays is fundamental for both understanding the mechanisms of Parkinson's disease and developing anti-Parkinson drugs.In this paper,we summarize the method of behavioral experiments of Parkinson's disease using mice and rats at home and abroad and systematically summarize the experimental equipment,experimental method,evaluation indexes,and precautions of commonly used Parkinson's behavioral experiments.We also provide an overview of the commonly used animal models of Parkinson's disease and analyze their modeling mechanisms,alignment with the clinical features of Parkinson's disease,and respective advantages and disadvantages.This analysis will help researchers in choosing appropriate animal models of Parkinson's disease and behavioral testing method according to the purpose of the study.

Animal experiment courses are important for developing students'practical skills in medical and life science education.They help to cultivate students'experimental skills,scientific reasoning,and innovative thinking ability.However,the traditional teaching method used in animal experiment courses tend to focus on a single topic and have minimal student participation.Courses should aim to promote students'active learning and innovative thinking abilities,and this paper discusses the ways teaching in animal experiment courses can be reformed.First,the paper introduces the background and significance of teaching in animal experiment courses and emphasizes the importance of cultivating the students'abilities.Second,it puts forward the principles of improved animal experiment course teaching,including designing student-centered lessons,providing opportunities for problem solving and practical exploration,and promoting interdisciplinary integration.At the same time,we integrate an ethical review of the welfare of experimental animals in China.Then,from the aspects of course design,teaching method,and evaluation method,this paper expounds several concrete measures of teaching reform in animal experiment courses in detail.When designing a course,attention should be paid to the selection of challenging and exploratory experimental projects,and students'interests and professional needs should be fully considered.Using improved teaching method,students should be encouraged to actively participate in explorative and cooperative classes,be guided through problem solving tasks,and encouraged to cultivate innovative thinking.Diversified evaluation method,such as experimental reports,group discussions,and project presentations,should be used to comprehensively evaluate students'practical and innovative thinking abilities.Finally,with practical verification and effect evaluation,the experiences and outcomes from a reform of animal experiment course teaching are summarized,and suggestions for further improvements are put forward.
