This study examined the effect of islet macrophages on β-cell function changes during type 2 diabetes mellitus (T2DM) progression based on the traditional Chinese medicine theory that " moderate fire generating qi, hyperactive fire consuming qi" . T2DM is closely associated with chronic low-grade inflammation, with islet macrophages playing a central role in this process. Under physiological conditions, islet macrophages secrete anti-inflammatory and growth factors to regulate the immune response, promote cell proliferation, and support islet β-cell survival and function, reflecting the concept of " moderate fire generating qi" . However, during the pathological process of T2DM, islet macrophages become over-activated and dysfunctional, secreting large amounts of pro-inflammatory factors that trigger severe inflammatory responses and oxidative stress. This process damages islet β-cells, disrupts the islet microenvironment and blood supply, exacerbates local inflammation and structural damage, and worsens the survival environment of β-cells. Ultimately, this leads to fewer β-cells and function loss, aligning with the " hyperactive fire consuming qi" theory, where excessive fire depletes qi and blood. This study enhances the understanding and application of traditional Chinese medicine theories in modern medicine, offering a new perspective on T2DM prevention and treatment. Regulating islet macrophage function and reducing their pro-inflammatory responses may become key strategies for preserving β-cell function and slowing T2DM progression.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

Cholesterol is an essential molecule for the biosynthesis of cell membranes and cell proliferation and differentiation, and the liver plays a central role in cholesterol metabolism and is responsible for the synthesis, uptake, secretion, and transport of cholesterol. The initial stages of cholesterol synthesis in the liver are particularly important, and abnormalities in such stages are closely associated with the progression of various liver diseases. Studies have shown that as a key rate-limiting enzyme in cholesterol biosynthesis, 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) has well-defined regulatory properties and has been confirmed as an important target for the regulation of various liver diseases. This article reviews the process of cholesterol metabolism, the degradation and regulatory mechanisms of HMGCR, and the application of inhibitors, as well as the role of HMGCR in liver diseases, in order to provide new insights for scientific research and the clinical prevention and treatment of liver diseases.

Objective: To retrospectively compare the impact of different intraoperative transfusion strategies for platelets and cryoprecipitate on perioperative blood usage and clinical outcomes in patients undergoing orthotopic heart transplant (OHT), thereby providing a reference for perioperative patient blood management. Methods: The clinical data of 65 patients who had undergone OHT at our hospital between 2020 and 2025 were retrospective collected. Patient demographics, underlying chronic conditions, and perioperative (preoperative, intraoperative, and postoperative) laboratory blood test results were analyzed. The transfusion volumes of intraoperative red blood cells, plasma, platelets, and cryoprecipitate were examined. Univariate and multivariate logistic regression models were employed to identify factors associated with perioperative outcomes. Results: A total of 65 patients received allogeneic blood transfusion during the perioperative period. The ultilization of intraoperative platelets and cryoprecipitate was as follows: simultaneous transfusion of both platelets and cryoprecipitate (at a 1∶1 ratio) was administered in 42 patients (64.62%), platelets alone in 12 patients (18.46%), and cryoprecipitate alone in 11 patients (16.92%). Patients who received simultaneous transfusion of platelets and cryoprecipitate (1∶1) (n=42) had a shorter ICU length of stay (32.45±10.18 d), while those who received either platelets or cryoprecipitate alone (n=23) had a significantly longer ICU length of stay (68±15.97 d). Patients receiving simultaneous intraoperative transfusion of platelets and cryoprecipitate also required fewer units of allogeneic red blood cells intraoperatively (median=4 units) and had a lower mortality rate (16.7%) than those receiving either product alone (26.1%), with a statistically significant difference (P=0.023). Multivariate logistic regression analysis indicated that the volume of cryoprecipitate transfused was an independent protective factor against postoperative allogeneic red blood cell transfusion (OR=0.344, 95% CI [0.177, 0.829], P=0.0159). Multivariate logistic regression also identified cryoprecipitate transfusion volume as an independent protective factor for ICU length of stay (OR=0.877, 95% CI [0.719, 0.986], P=0.0008), which was in line with the multivariate Cox regression results. Conclusion: In patients undergoing OHT, the intraoperative transfusion strategy for platelets and cryoprecipitate influences the volume of perioperative allogeneic red blood cell transfusion and patient mortality. Intraoperative cryoprecipitate transfusion volume is an independent protective factor against both postoperative allogeneic red blood cell transfusion and prolonged ICU length of stay. The establishment of a multidisciplinary collaborative blood management model, combined with the modification of perioperative blood utilization practices and the implementation of a comprehensive patient blood management strategy, can holistically ensure perioperative patient safety.

AIM: To explore the current status, research hotspots, and trends of global uveitis research to provide a theoretical basis and references for researchers in the field of uveitis, and promote further development in this area.METHODS: Relevant literatures on uveitis were retrieved from the China National Knowledge Infrastructure(CNKI)database, Wanfang database, and Web of Science core collection database since their establishment until 24 August 2023. The country/publishing institutions, research authors, high-frequency keywords, and burst keywords were visual analyzed by using software such as GraphPad Prism 9, CiteSpace 6.2. R2, and VOSviewer.RESULTS: Research teams for uveitis have been formed in various countries globally. The top three countries in terms of publications are the United States of America(7 585 papers), the United Kingdom(2 412 papers)and Germany(1 679 papers). The top three foreign institutions in terms of publications are Harvard University, Oregon Health & Science University, and Moorfields Eye Hospital, while the top three domestic institutions are Affiliated Eye Hospital of Shandong University of Traditional Chinese Medicine, Chongqing Medical University, and Zhongshan Ophthalmic Center, Sun Yat-sen University. The analysis of high-frequency keywords and burst keywords in Chinese and English shows that research hotspots mainly focus on exploring pathogenesis and different treatment methods for uveitis. The research hotspots related to uveitis treatment are transitioning to molecular biology-related research topics, such as molecular biological signaling pathways(NF-κB signaling pathway with a strength value of 22.89), biological agents(adalimumab with a strength value of 32.21), and tumor necrosis factor(with a strength value of 48.44). Related research is also expanding to basic experiments on relevant rats.CONCLUSIONS: In recent years, the research hotspots and trends of global uveitis mainly focus on precise diagnosis, pathogenesis, and more effective treatment methods. It is important for more scholars to dedicate themselves to uveitis-related research in the future to make breakthroughs and progress in the field. More large-scale and multicenter clinical studies on uveitis can provide high-quality research evidence.
