ObjectiveTo observe the effect of M1 bone marrow-derived macrophages (M1-BMDM) with Wnt5a knockdown on liver fibrosis and regeneration in a rat model of liver cirrhosis, and to investigate its gain-of-function effect compared with unmodified M1-BMDM. MethodsPrimary bone marrow-derived macrophages were isolated from rats and were polarized to M1 phenotype to construct M1-BMDMWnt5a-KD cells. A rat model of liver cirrhosis induced by CCl4/2-AAF was established, and at the end of week 8, rats were randomly divided into model group, M1-BMDM group, M1-BMDM Wnt5a-knockdown empty vector group (M1-BMDMKD-EV group), and M1-BMDM Wnt5a-knockdown group (M1-BMDMWnt5a-KD group), with 6 rats in each group. On the first day of week 9, the rats in each group were given a single injection of the corresponding cells via the caudal vein, along with an intraperitoneal injection of a CCR2 inhibitor. Six rats without any treatment were used as normal control group. Samples were collected at the end of week 12 to assess liver histopathology, serum liver function parameters, hepatic stellate cell activation, and the expression levels of mature hepatocyte markers. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the model group, all cell treatment groups had significant alleviation of liver inflammatory response and significant reductions in the activities of alanine aminotransferase and aspartate aminotransferase (AST) in serum (all P<0.01), and the M1-BMDMWnt5a-KD group had a significantly lower serum level of AST than the M1-BMDM group (P<0.05). The semi-quantitative analysis based on immunohistochemical staining showed that compared with the model group, all cell treatment groups had a significant reduction in the percentage of CD68-positive area (all P<0.05), and compared with the M1-BMDMKD-EV group, the M1-BMDMWnt5a-KD group had a significant reduction in the percentage of CD68-positive area and a significant increase in the percentage of CD163-positive area (both P<0.05). Compared with the model group, all cell treatment groups had significant reductions in the mRNA expression levels of CD68 and tumor necrosis factor-α (all P<0.05) and the protein expression level of CD68 (all P<0.01); compared with the M1-BMDMKD-EV group, the M1-BMDMWnt5a-KD group had significant increases in the protein and mRNA expression levels of CD163 (both P<0.05), significant reductions in the protein and mRNA expression levels of CD68 (both P<0.05), and a significant reduction in the protein expression level of tumor necrosis factor-α (P<0.01). Sirius Red collagen staining and alpha-smooth muscle actin (α-SMA) immunohistochemical staining showed that compared with the model group, all cell treatment groups had significant alleviation of liver collagen deposition and α-SMA-positive area, with the most significant changes in the M1-BMDMWnt5a-KD group, and compared with the M1-BMDMKD-EV group, the M1-BMDMWnt5a-KD group had significantly smaller Sirius Red-positive area and α-SMA-positive area and a significantly lower content of hydroxyproline in liver tissue (all P<0.05). Compared with the M1-BMDMKD-EV group, the M1-BMDMWnt5a-KD group had significant reductions in the protein and mRNA expression levels of α-SMA and the mRNA expression level of COL-I and TGF-β (all P<0.05). Compared with the model group, all cell treatment groups had a significant increase in the protein expression level of HNF-4α in liver tissue (all P<0.05), and the M1-BMDMWnt5a-KD group had significantly higher protein and mRNA expression levels of HNF-4α and hepatocyte specific antigen than the M1-BMDMKD-EV group (both P<0.05). The M1-BMDMWnt5a-KD group had a significantly higher serum level of albumin than the M1-BMDMKD-EV group (P<0.01). Immunofluorescence co-staining showed that compared with the model group, all cell treatment groups had a significant increase in the number of cells stained positive for HNF and HNF-4α and Ki67 (all P<0.01), and the M1-BMDMWnt5a-KD group had a significantly higher number of such cells than the M1-BMDMKD-EV group (P<0.05). ConclusionInhibition of Wnt5a expression enhances the therapeutic effect of M1-BMDM on rats with liver cirrhosis induced by CCl4/2-AAF, which provides new ideas for enhancing the anti-cirrhotic effect of M1-BMDM through genetic modification.

Objective: To investigate the incidence, characteristics, and influencing factors of resolution discrepancies within the minipool (MP) testing model across Chinese blood station laboratories in 2024. Methods: A nationwide, multicenter, cross-sectional study was conducted, including 334 blood station laboratories that reported nucleic acid reactive data among enzyme immunoassay non-reactive samples. Of these, 296 laboratories adopted the pool resolution model, with a total of 12 536 273 samples tested. Systematic analysis was performed on resolution data, focusing on the MP-NAT reactivity rate, the pool resolution concordance rate, and the resolution discrepancy rate. Subgroup analyses were conducted based on reagent types, viral targets, and Ct values. Potential causes were further explored through laboratory surveys and re-examination of raw amplification curves. Results: In 2024, the national average MP-NAT reactivity rate was 0.15%. The overall pool resolution concordance rate was 57.86%, which showed a gradual decline as Ct values increased across all reagents. The national average resolution discrepancy rate was 0.081‱(102/12 536 273), with 17.91%(53/296) of laboratories reporting at least one discrepancy. Nine reagent types were associated with these events, exhibiting reagent-specific patterns. For Reagent A2, the predominant discrepancy was HBV reactive pools resolving as HIV (36.36%); for Reagent D1, HBV pools frequently resolved as HCV (38.89%); and for Reagent E, the most common pattern was HIV pools resolving as HBV (48.00%). These resolution discrepancies were strongly associated with high Ct values: the median pool Ct for HBV exceeded 38, while those for HCV and HIV both exceeded 40. Investigations across 16 laboratories revealed that most discrepant samples exhibited “tailing” amplification curves, with some cases linked to cross-contamination or reagent batch-specific issues. Conclusion: While the incidence of resolution discrepancies in the MP-NAT model remains low in China, variations exist across different reagents and laboratories. These discrepancies are closely associated with low viral load, reagent performance, and laboratory operational practices.

With the continuous development of new surgical technology, new equipment and new concepts, the research focused in the field of surgery is also in constant change. Among them, there are still confusion and controversies in the current clinical practice when facing the one-stop proposition of benefit population screening, advantageous surgical indication decision-making, surgical intervention timing selection, postoperative complication prediction and management. Therefore, our team tries to analyze whether the concept of"co-management of liver and pancreas"exists in clinical practice from the aspects of anatomy, physiology, histology and embryology of liver and pancreas, as well as the interaction between liver and pancreas, and explore the relationship between liver and pancreas in anatomy and tissue embryonic development, and the relationship between the concept of"co-management of liver and pancreas"and pancreatitis and pancreatic tumors as well as the concept of “co-management of liver and pancreas” applied in neoadjuvant chemoradiotherapy, and attempts to establish a new treatment pathway for pancreatic diseases based on this concept, in order to provide a new idea, new scheme and new possibility for the clinical research of pancreatic diseases and pancreatic surgery.

Objective To analyze the trends in the disease burden of tracheal, bronchus, and lung cancer (TBL) in China and in low-, middle-, and high-socio-demographic index (SDI) countries and regions from 1990 to 2021, with the aim of providing evidence for the formulation of targeted prevention and control strategies. Methods Utilizing data from the Global Burden of Disease (GBD) Study 2021, we extracted TBL-related data from 1990 to 2021, stratified by sex, age group, and year. We assessed the disease burden and trends of TBL across different groups, conducted a decomposition analysis to identify the leading contributors to the change in disease burden, and examined the relationship between disability-adjusted life years (DALYs) and SDI. Results In 2021, the overall burden of TBL in China was substantially higher than that in other groups. The fold-increase in the number of prevalent cases, deaths, and DALYs was significantly greater in China. Moreover, the growth rates of the age-standardized prevalence rate (ASPR), age-standardized mortality rate (ASMR), and age-standardized DALYs rate (ASDR) in China were higher than the overall levels in other SDI countries. In all groups, the ASPR of TBL generally followed a pattern of increasing and then decreasing with age; however, for males in China and middle-SDI countries, the ASPR exhibited a decline in the 80-84 age group. Decomposition analysis revealed that the primary drivers of the increasing TBL burden varied among groups: the rise in DALYs in China and middle-SDI countries was mainly driven by population aging, in low-SDI countries by population growth, and in high-SDI countries by epidemiological transition. While global health inequality in TBL showed some improvement, low-SDI countries continued to bear a disproportionately heavy health burden. Conclusion The disease burden of TBL in China has progressively increased from 1990 to 2021, now ranking among the highest globally. Multiple factors, predominantly driven by population aging, are exacerbating this burden. The burden of TBL is influenced by advancing age, sex differences, and SDI levels. China, along with low- and middle-SDI countries, should implement targeted intervention strategies based on epidemiological findings, including expanding investment in public health services and strengthening healthcare systems, to mitigate the growing burden of TBL.

Diabetic kidney disease(DKD) is a chronic kidney structural and functional disorder caused by diabetes. With the global prevalence of diabetes continuing to rise, DKD has gradually become a major cause of chronic kidney disease and end-stage renal disease(ESRD), posing a serious threat to patients' quality of life and long-term health outcomes. Studies have shown that apoptosis plays a pivotal role in the development and progression of DKD, with its mechanisms involving abnormal activation of multiple signaling pathways such as Toll-like receptor 4(TLR4)/nuclear transcription factor-κB(NF-κB)/B-cell lymphoma-2(Bcl-2)/cysteinyl aspartate-specific proteinase(Caspase)-3, protein kinase R-like endoplasmic reticulum kinase(PERK)/eukaryotic initiation factor 2α(eIF2α)/activating transcript factor 4(ATF4)/CCAAT enhancer-binding protein homologous protein(CHOP), phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/glycogen synthase kinase-3β(GSK-3β), Janus kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3), adenosine monophosphate-activated protein kinase(AMPK)/mammalian target of rapamycin(mTOR) and silent information regulator 1(SIRT1)/tumor suppressor protein 53(p53), thereby accelerating renal pathological damage in DKD. Extensive evidence-based medical studies have confirmed that traditional Chinese medicine(TCM), leveraging its unique therapeutic advantages of multi-target, multi-component and multi-pathway approaches, has demonstrated remarkable efficacy and favorable safety profiles in treating DKD. Recent studies have demonstrated that active components of TCM can specifically target and modulate key effectors in apoptotic signaling pathways. Meanwhile, traditional compound formulations exert synergistic effects through multiple approaches such as replenishing deficiency and activating blood circulation, detoxifying and dredging collaterals, tonifying kidney essence, and removing stasis and purging turbidity, thereby comprehensively regulating critical pathological processes including endoplasmic reticulum stress and mitochondrial apoptosis pathways. This combined therapeutic approach of molecular targeting and holistic regulation provides novel strategies for delaying the progression of DKD. Based on this, this paper provides an in-depth analysis of key apoptotic signaling pathways and their regulatory mechanisms, while systematically summarizing recent research advances regarding the therapeutic effects of TCM active components, compound formulations, and proprietary Chinese medicines on DKD through modulation of these pathways, with particular emphasis on their underlying molecular mechanisms. These findings not only elucidate the modern scientific connotation and theoretical basis of TCM in treating DKD but also establish a solid theoretical and practical foundation for promoting the wider clinical application and further research of TCM in the field of DKD treatment.

ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Existentialist philosophy focuses on human existence, explores subjectivity and uniqueness, and highlights the value of human existence. Advanced cancer patients generally suffer immense existential distress, each with their own modes of appearance and numerous possibilities. From the perspective of existentialist philosophy, targeting the group of advanced cancer patients, this paper clarified the analysis of “Dasein” (holistic phenomenon and modes of appearance). Through recognition (achieving to deepen the inner scope of the subject and object) and comprehension (seeking appropriate “self-knowledge”), it introduced the planning of variable possibilities. Subsequently, based on the patients’ pre-possessing, pre-seeing, and pre-grasping, explanatory activities were carried out to complete the “self-formation” in the planning. Ultimately, it facilitated the realization of existential meaning in the presupposition and proposed actionable clinical practices (meaning therapy and emotional touch therapy) to alleviate the existential distress of advanced cancer patients.

Climate change is altering the Earth's water cycle system. The resulting three extreme weather events—heatwaves, droughts, and extreme precipitation—impacts urban and rural water security through multi-layered mechanisms. A primary structural disparity exists between urban and rural systems: while urban areas benefit from comprehensive and standardized pipe networks that ensure terminal water quality, rural areas often suffer from "last mile" vulnerability due to inadequate infrastructure and outdated purification facilities. Extreme weather can directly alter the microbial community structure, concentrations of chemical pollutants and physicochemical properties of source water. These alterations interfere with the efficiency of water treatment processes and ultimately compromise the integrity of distribution systems. Because distribution networks often lack real-time monitoring and adaptive response capabilities, they have emerged as the most vulnerable link in the "water source-water treatment-distribution system" chain. Based on a systematic analysis of these chain-wide impacts, this paper proposed a series of control strategies, including security frameworks based on multi-model coupling and water source protection measures, improvement of water treatment technologies, optimization of distribution systems, and development of new water quality monitoring methods. These strategies aim to enhance the climate adaptability of urban and rural drinking water systems through multi-dimensional intervention, providing a theoretical basis for constructing climate-resilient water infrastructure.

Traditional treatment for type 1 diabetes mellitus (T1DM) primarily involves insulin replacement, yet some patients encounter issues such as significant blood glucose fluctuations, high risk of hypoglycemia, and weight gain. In recent years, the adjuvant therapeutic role of non-insulin hypoglycemic drugs in T1DM has gradually gained attention. This article reviews the mechanisms of action and clinical research progress of five types of non-insulin hypoglycemic drugs in the treatment of T1DM: amylin analogues (pramlintide), biguanides (metformin), sodium-glucose co-transporter 2 inhibitor, dipeptidyl peptidase-4 inhibitor, and glucagon-like peptide-1 receptor agonist. It is found that these drugs can enhance clinical benefits for T1DM patients by improving insulin sensitivity, delaying gastric emptying, promoting urinary glucose excretion, and regulating incretin levels, thereby reducing glycated hemoglobin levels, decreasing insulin dosage, and managing body weight. Simultaneously, these drugs also present limitations such as low patient compliance due to complex dosing regimens, increased risk of diabetic ketoacidosis, and heterogeneity in glycemic control. Future research could focus on developing individualized treatment strategies, combining pharmacogenomics with novel biomarkers to precisely identify subpopulations of patients who may benefit, and delving into the potential value of these drugs in delaying diabetic vascular complications and improving patients’ quality of life.
