BACKGROUND: Approximately 40% of individuals with diabetes worldwide are at risk of developing diabetic kidney disease (DKD), which is not only the leading cause of kidney failure, but also significantly increases the risk of cardiovascular disease, causing significant societal health and financial burdens. This study aimed to describe the burden of DKD and explore its cross-country epidemiological status, predict development trends, and assess its risk factors and sociodemographic transitions. METHODS: Based on the Global Burden of Diseases (GBD) Study 2021, data on DKD due to type 1 diabetes (DKD-T1DM) and type 2 diabetes (DKD-T2DM) were analyzed by sex, age, year, and location. Numbers and age-standardized rates were used to compare the disease burden between DKD-T1DM and DKD-T2DM among locations. Decomposition analysis was used to assess the potential drivers. Locally weighted scatter plot smoothing and Frontier analysis were used to estimate sociodemographic transitions of DKD disability-adjusted life years (DALYs). RESULTS: The DALYs due to DKD increased markedly from 1990 to 2021, with a 74.0% (from 2,227,518 to 3,875,628) and 173.6% (from 4,122,919 to 11,278,935) increase for DKD-T1DM and DKD-T2DM, respectively. In 2030, the estimated DALYs for DKD-T1DM surpassed 4.4 million, with that of DKD-T2DM exceeding 14.6 million. Notably, middle-sociodemographic index (SDI) quintile was responsible for the most significant DALYs. Decomposition analysis revealed that population growth and aging were major drivers for the increased DKD DALYs in most regions. Interestingly, the most pronounced effect of positive DALYs change from 1990 to 2021 was presented in high-SDI quintile, while in low-SDI quintile, DALYs for DKD-T1DM and DKD-T2DM presented a decreasing trend over the past years. Frontiers analysis revealed that there was a negative association between SDI quintiles and age-standardized DALY rates (ASDRs) in DKD-T1DM and DKD-T2DM. Countries with middle-SDI shouldered disproportionately high DKD burden. Kidney dysfunction (nearly 100.0% for DKD-T1DM and DKD-T2DM), high fasting plasma glucose (70.8% for DKD-T1DM and 87.4% for DKD-T2DM), and non-optimal temperatures (low and high, 5.0% for DKD-T1DM and 5.1% for DKD-T2DM) were common risk factors for age-standardized DALYs in T1DM-DKD and T2DM-DKD. There were other specific risk factors for DKD-T2DM such as high body mass index (38.2%), high systolic blood pressure (10.2%), dietary risks (17.8%), low physical activity (6.2%), lead exposure (1.2%), and other environmental risks. CONCLUSIONS DKD markedly increased and varied significantly across regions, contributing to a substantial disease burden, especially in middle-SDI countries. The rise in DKD is primarily driven by population growth, aging, and key risk factors such as high fasting plasma glucose and kidney dysfunction, with projections suggesting continued escalation of the burden by 2030.

Objective:To investigate the effect and preliminary mechanism of hypervirulent Klebsiella pneumoniae (hvKP) on the immune response to sepsis induced by liver abscess in mice. Methods:C57BL/6 mice were intraperitoneally injected with hvKP strain NTUH-K2044 or classical Klebsiella pneumoniae (cKP) strain HS11286 suspension to prepare the model of sepsis. The survivals rates of mice within 24 h were recorded. HE staining was used to observed the inflammatory cell infiltration in mouse liver tissues. The levels of neutrophil marker lymphocyte antigen 6G (Ly6G) in mouse liver tissues were detected by immunohistochemistry. The activity of reactive oxygen species (ROS) in mouse liver macrophages and peripheral blood monocytes was measured by ROS assay kit. The activation of p105/p50 and p65 in NF-κB signaling pathway in mouse liver macrophages and peripheral blood monocytes was detected by Western blot. The expression of IL-1β, IL-6 and TNF-α at mRNA and protein levels in mouse liver macrophages and peripheral blood monocytes were detected by qRT-PCR and ELISA, respectively. One-way analysis of variance and t test were used for statistical analysis. Results:Compared with cKP, hvKP infection could induce C57BL/6 mice to develop obvious liver abscess with massive inflammatory cell infiltration. Moreover, the level of Ly6G in liver tissues was significantly higher in hvKP-infected mice than in cKP-infected mice ( P<0.000 1), but the survival rate of hvKP-infected mice was significantly lower than that of cKP-infected mice ( P<0.000 1). hvKP significantly promoted the ROS activity ( P<0.000 1) and enhanced the phosphorylation of p105/p50 and p65 in NF-κB signaling pathway in mouse liver macrophages and peripheral blood monocytes as compared with cKP ( P<0.001). The expression of IL-1β, IL-6 and TNF-α at mRNA and protein levels in mouse liver macrophages and peripheral blood monocytes were significantly higher in hvKP-infected mice than in cKP-infected mice ( P<0.001). Conclusion:hvKP can promote the development of liver abscess and induce sepsis in mice.

Objective:To investigate the role of TcpC, a virulence factor of uropathogenic Escherichia coli (UPEC), in inhibiting the formation of neutrophil extracellular traps (NETs) in mouse bone marrow neutrophils, and to analyze its pathogenic mechanism. Methods:C57BL/6 mice were injected with either wild-type (CFT073 wt) or tcpc gene-knockout UPEC CFT073(CFT073 Δ tcpc) to establish a mouse model of cystitis. Mice were sacrificed 3 d post-infection, and their bladders were collected to observe gross pathological changes. Hematoxylin-eosin (HE) staining was used to assess histopathological changes in bladder tissues, and immunohistochemistry was performed to localize TcpC in bladder tissues. Bacterial loads in urine samples were quantified using the ten-fold dilution method, and the presence of tcpc gene in genomic DNA from bladder or urine samples was confirmed by PCR. The expression of TcpC at mRNA and protein levels in mouse bone marrow nuetrophils infected with CFT073 wt was detected by qRT-PCR and Western blot. The effects of UPEC infection on expression of NETs-related proteins and the production of pro-inflammatory factors in mouse bone marrow neutrophils were analyzed by Western blot and ELISA, respectively. Reactive oxygen species(ROS) level and bacterial viability in mouse bone marrow nuetrophils were measured using ROS and bacterial viability detection kits. Results:Compared to the CFT073 Δ tcpc group, the bladder of CFT073 wt group mice exhibited significant enlargement, extensive inflammatory cell infiltration, and the presence of TcpC in bladder tissue. The bacterial load in the urine of CFT073 wt -infected mice was significantly higher than that in the CFT073 Δ tcpc group ( P<0.01). PCR confirmed the presence of the tcpc gene in bladder and urine samples from CFT073 wt-infected mice. Increased expression of TcpC at both mRNA and protein levels was observed in CFT073 wt-infected mouse bone marrow neutrophils. CFT073 wt infection inhibited the mRNA and protein expression of NETs-related proteins and reduced the production of pro-inflammatory factors in mouse bone marrow neutrophils. TcpC suppressed ROS level and promoted the survival of CFT073 wt in mouse bone marrow neutrophils. Conclusions:TcpC enhances the pathogenicity of UPEC CFT073 by inhibiting the formation and activation of NETs in mouse bone marrow neutrophils. This study provides new insights into the pathogenic mechanisms of UPEC and the immune evasion strategies of other pathogenic bacteria, as well as potential targets for clinical prevention and treatment of UPEC-induced urinary tract infections.

Objective:To study the effects of hypoxia on the autophagy level in the spleen of mice with OSAHS.Methods:Mouse OSAHS hypoxia model was established in 24 C57BL/6 mice and the mice were divided into 3 groups:normoxic group,hypoxic group and resveratrol group(n=8).Real time PCR,Western blot and immunohistochemical staining(IHC)were used to detect the mRNA and protein expression of autophagy related proteins microtube associated protein 1 light chain 3 B(LC3B),myosin-like BCL2 inteacting protein(Beclin1)and autophagy related gene 5(ATG5)in mouse spleen respectively.Results:The mRNA expres-sion of LC3B,Beclin1,and ATG5 in the hypoxic group was lower than that in the normoxic group(P＜0.01,P＜0.01,P＜0.001),resveratrol upregulated the expression levels of LC3B and ATG5 mRNA in the hypoxic group(P＜0.05,P＜0.001),but did not up-regulate the expression of Beclin1(P＞0.05).The protein expression levels of LC3B,Beclin1 and ATG5 in the hypoxic group were lower than that in the normoxic group(P＜0.05,P＜0.05,P＜0.01).Resveratrol upregulated the expression levels of LC3B and ATG5 in the hypoxic group(P＜0.05,P＜0.01),but did not upregulated the expression of Beclin1(P＞0.05).IHC test showed that the expression level of LC3B,Beclin1 and ATG5 in the hypoxic group was lower than that in the normoxic group(P＜0.01,P＜0.01,P＜0.001).Resveratrol increased the expression level of LC3B and ATG5 in the hypoxic group(P＜0.05,P＜0.01),but did not upregulate the expression of Beclin1(P＞0.05).Conclusion:Hypoxia may inhibite the autophagy level of spleen in mice.Resvera-trol derivatives increases the autophagy level of mice under hypoxia condition,but has no significant effect on Beclin1 expression.

Objective:To establish a model for the combined detection of serum copeptin and inflammatory markers in acute stroke (AS), and to explore the value of copeptin and inflammatory marker detection in the clinical diagnosis and prognosis assessment of AS.Methods:A total of 75 patients were diagnosed with acute ischemic stroke (AIS) [46 males, age (64.1±11.7) years] and 45 patients with acute intracerebral hemorrhage (ICH) [28 males, age (61.0±13.9) years] who were admitted to the First Affiliated Hospital of Hunan University of Chinese Medicine through the emergency department from January 1 to July 31, 2024, were included as the observation group. Meanwhile, 60 healthy individuals [39 males, age (64.4±8.2) years] were selected as the control group (HC). The differences in serum copeptin levels and inflammatory markers among different groups were compared. ROC curves were drawn to analyze the value of copeptin and inflammatory markers in the clinical diagnosis and prognosis assessment of AIS. The Kaplan-Meier method was used to draw survival curves to analyze the in-hospital survival rates of patients in different groups. Cox regression analysis was conducted to identify the risk factors affecting the prognosis of AIS patients.Results:The level of copeptin was significantly elevated in AS, with the results showing ICH>AIS>HC ( H=100.11, P<0.001). Copeptin demonstrated the highest efficacy in the early diagnosis of AIS and ICH (AUC=0.893, sensitivity 89.3%, specificity 75.0%; AUC=0.986, sensitivity 95.6%, specificity 93.3%) and the assessment of prognosis (AUC=0.997, sensitivity 100%, specificity 96.8%; AUC=0.907, sensitivity 86.7%, specificity 86.7%), outperforming other single indicators. The combined detection of copeptin with the neutrophil-to-lymphocyte ratio (NLR) and the systemic immune-inflammation index (SIIRI) was the best combination for the early diagnosis of AIS and ICH (AUC=0.937, sensitivity 77.3%, specificity 98.3%; AUC=0.989, sensitivity 95.6%, specificity 95.0%) and for the assessment of prognosis (AUC=0.996, sensitivity 100%, specificity 96.8%; AUC=0.944, sensitivity 86.7%, specificity 90.0%). Kaplan-Meier survival curves showed that AIS patients in the low-value group of copeptin and NLR had a higher survival rate during hospitalization than those in the high-value group ( HR 54.46, 7.608, P<0.01, respectively), and ICH patients in the low-value group of copeptin, SIIRI, SIRI, and SII had a higher survival rate during hospitalization than those in the high-value group ( HR 12.67, 7.923, 3.567, 5.925, P<0.05); Cox regression showed that copeptin, NLR, NIHSS, and mRS were independent risk factors affecting the prognosis of patients with AIS ( HR 1.421, 1.368, 1.158, and 1.188, respectively, P<0.05), copeptin and SIIRI were independent risk factors affecting the prognosis of ICH ( HR 1.308, 1.113, P<0.05), and GCS was a protective factor affecting ICH prognosis ( HR=0.741, P<0.05). Conclusion:Copeptin and inflammatory indicators can reflect the severity of different subtypes of stroke. The single or combined detection shows good value in the clinical application of AS. The combination of copeptin-NLR and copeptin-SIIRI is respectively the best comprehensive biomarker combination for the early diagnosis and prognosis assessment of AIS and ICH.
