The occurrence of diabetes mellitus (DM) is closely related to insulin resistance and islet β cell dysfunction. Modern studies have found that macrophages are widely present in the liver,fat,skeletal muscle,islets, and other tissues and organs. Macrophage M1/M2 polarization plays an important role in the occurrence and development of diabetes mellitus and its related complications by intervening in inflammatory response,improving insulin resistance,and promoting tissue repair. Most of the traditional Chinese medicines that regulate the activation and polarization of macrophages are Qi-replenishing and Yin-nourishing,heat-clearing, and detoxicating medicinal,which are consistent with the etiology and pathogenesis of diabetes and its related complications. Therefore,by summarizing the mechanisms between macrophage activation,polarization, and insulin resistance in various tissues,this paper reviewed traditional Chinese medicine and its effective components and compounds in improving diabetes mellitus and its related complications through multi-channel regulation of macrophage polarization and regulation of M1/M2 ratio,providing references for the future treatment of DM and its related complications with traditional Chinese medicine.

Animal experiments are an essential component of life sciences and medical research. However, the external validity and reliability of individual animal studies are frequently challenged by inherent limitations such as small sample sizes, high design heterogeneity, and poor reproducibility, which impede the effective translation of research findings into clinical practice. Systematic reviews and meta-analysis represent a key methodology for integrating existing evidence and enhancing the robustness of conclusions. Currently, however, the application of systematic reviews and meta-analysis in the field of animal experiments lacks standardized guidelines for their conduct and reporting, resulting in inconsistent quality and, to some extent, diminishing their evidence value. To address this issue, this paper aims to systematically delineate the reporting process for systematic reviews and meta-analysis of animal experiments and to propose a set of standardized recommendations that are both scientific and practical. The article's scope encompasses the entire process, from the preliminary preparatory phase [including formulating the population, intervention, comparison and outcome (PICO) question, assessing feasibility, and protocol pre-registration] to the key writing points for each section of the main report. In the core methods section, the paper elaborates on how to implement literature searches, establish eligibility criteria, perform data extraction, and assess the risk of bias, based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement, in conjunction with relevant guidelines and tools such as Animal Research: Reporting of in Vivo Experiments (ARRIVE) and a risk of bias assessment tool developed by the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE). For the presentation of results, strategies are proposed for clear and transparent display using flow diagrams and tables of characteristics. The discussion section places particular emphasis on how to scientifically interpret pooled effects, thoroughly analyze sources of heterogeneity, evaluate the impact of publication bias, and cautiously discuss the validity and limitations of extrapolating findings from animal studies to clinical settings. Furthermore, this paper recommends adopting the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to comprehensively grade the quality of evidence. Through a modular analysis of the entire reporting process, this paper aims to provide researchers in the field with a clear and practical guide, thereby promoting the standardized development of systematic reviews and meta-analysis of animal experiments and enhancing their application value in scientific decision-making and translational medicine.

Nanozymes are a distinct category of nanomaterials that exhibit catalytic properties resembling those of enzymes such as peroxidase (POD), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). Nanozymes derived from Chinese herbal medicines exhibit the catalytic functions of their enzyme mimics, while retaining the specific medicinal properties of the herb (termed "herbzymes"). These nanozymes can be categorized into three main groups based on their method of synthesis: herb carbon dot nanozymes, polyphenol-metal nanozymes, and herb extract nanozymes. The reported catalytic activities of herbzymes include POD, SOD, CAT, and GPx. This review presents an overview of the catalytic activities and potential applications of nanozymes, introduces the novel concept of herbzymes, provides a comprehensive review of their classification and synthesis, and discusses recent advances in their biomedical applications. Furthermore, we also discuss the significance of research into herbzymes, including the primary challenges faced and future development directions.

Integrating evidence from animal experiments is a critical component of biomedical research, providing essential prior information for in-depth investigations of disease mechanisms and new drug development. Animal models have played an irreplaceable role in simulating human diseases. However, the integration of evidence from animal experiments has faced numerous challenges, including insufficient emphasis, significant heterogeneity in study designs, high publication bias, and discrepancies with clinical research practices. This paper first identifies existing issues in the original research evidence from animal experiments, such as the selection and applicability of animal models, considerations in the design of experimental studies, and factors influencing the translation of animal experimental evidence. It then discusses various methods for integrating this evidence, including systematic review and meta-analysis, overview of systematic review/umbrella review, scoping review, and evidence mapping, while highlighting recent advancements in their application. Finally, the paper addresses the main challenges currently encountered in the integration of evidence from animal experiments and proposes targeted improvement strategies aimed at enhancing the efficiency of translating research outcomes into clinical practice and promoting the advancement of evidence-based medicine. By continuously optimizing original experimental research protocols and evidence integration practices, this work aims to establish a more efficient and scientific environment for the synthesis of evidence from animal experiments, ultimately contributing to clinical trials and human health.

The theory of "linkage between spleen and small intestine" has been put forward by doctors as early as the Ming dynasty. In traditional Chinese medicine, the spleen and small intestine cooperate and work together physiologically, and they are also closely related and interact with each other pathologically. The spleen governs transportation and transformation, which involves the function of the small intestine in transforming water and grain. The small intestine, governing the receiving and transformation of substances, depends on the normal transportation of the spleen. At the same time, it provides guarantee for the spleen to transform Qi and generate blood as well as ascend lucidity and descend turbidity. The dysfunction of spleen in transportation is closely related to the dysfunction of small intestine. The stability of intestinal microecology necessitates the normal functioning of the spleen. When the original balance of intestinal flora is disturbed, the spleen functioning will be affected. This study explored the pathogenesis and treatment of diabetes based on the physiological functions of the spleen and small intestine and the Western medicine targets of "nutrients-intestinal flora". According to modern medicine, nutrients are essential to maintain the normal physiological activities of the human body. Proper intake of nutrients can affect the absorption and metabolism of the human body for nutrients by regulating the composition and function of intestinal flora, so as to prevent the occurrence of diabetes. The imbalance of intestinal flora which harbors rich microorganisms may lead to the disturbance of energy metabolism and the dysfunction of the immune system, eventually leading to diabetes. As a metabolic disease, diabetes is closely related to the imbalance of intestinal flora and nutrient intake. Based on the theory of "linkage between spleen and small intestine", this paper discusses the relationship between spleen and small intestine. Furthermore, this paper discusses the correlation between "spleen-small intestine" and "nutrients-intestinal flora" by reviewing the latest progress in modern medicine and clinical research, aiming to provide a theoretical basis and new ideas for the clinical prevention and treatment of type 2 diabetes mellitus.

BACKGROUND:In recent years,the treatment of anterior cruciate ligament injury has become more and more mature.However,there are still disputes about the timing of surgery,the choice of surgical methods,the choice of grafts,and the methods to promote graft healing after anterior cruciate ligament injury. OBJECTIVE:To summarize the latest research progress of surgical timing,surgical methods,graft selection and methods to promote graft healing after anterior cruciate ligament injury,and to find new treatment directions for anterior cruciate ligament injury. METHODS:Relevant articles concerning anterior cruciate ligament injury were retrieved from PubMed,CNKI,WanFang Date,VIP,SinoMed,ScienceDirect,Springer and Cochrane Library.After the screening,72 related articles were finally included. RESULTS AND CONCLUSION:(1)Surgical timing:Compared with delayed anterior cruciate ligament reconstruction,early reconstruction can reduce meniscus injury,elevate quality of life,and improve functional recovery.However,it is still uncertain whether the different operation timing will accelerate cartilage injury.(2)Surgical methods:Arthroscopic anterior cruciate ligament reconstruction is a common surgical method for anterior cruciate ligament injury.Dynamic internal stabilization repair of anterior cruciate ligament can bring similar results to traditional anterior cruciate ligament reconstruction in short-term and long-term effects.(3)Graft selection:Autogenous hamstring tendon is the first choice of anterior cruciate ligament graft,while bone-patellar tendon-bone grafts and allografts are the secondary choices.(4)Among the methods to promote graft healing,suture band strengthening can increase knee joint stability and ensure graft healing.Stem cells promote the tendon-bone healing of grafts through anti-inflammatory action,angiogenesis,inhibition of osteolysis and promotion of chondrocyte differentiation.Preserving the residual end of the anterior cruciate ligament can maintain the stability of the knee joint,promote the recovery of proprioception,and provide a prerequisite for the healing of the graft.The effectiveness of platelet-rich plasma in promoting graft healing remains to be discussed.However,biomaterials,gene therapy,stem cell application and other methods to promote tendon healing remain in the stage of molecular and animal researches.Clinical transformation is also needed in the future.
