Purpose: Combinations of immune checkpoint inhibitors (ICIs) and chemotherapy have become the standard first-line treatment for human epidermal growth factor receptor 2 (HER-2)-negative advanced gastric cancer. However, primary resistance remains a challenge, with no effective biomarkers available for its prediction. This retrospective study explores the relationship between the baseline inflammatory burden index (IBI) and primary resistance in such context. Materials and Methods: We analyzed 62 patients with HER-2-negative advanced gastric cancer who received ICIs and chemotherapy as their first-line treatment. The IBI was calculated as follows: C-reactive protein (mg/L) × neutrophil count (10 3 /mm 3 )/lymphocyte count (10 3 /mm 3 ). Based on disease progression within 6 months, patients were categorized into the primary resistant or the control group. We compared baseline characteristics and IBI scores between the groups and assessed the predictive value of the IBI using the receiver operating characteristic curve. Both univariate and multivariate binary logistic regression analyses were conducted to identify factors influencing primary resistance. Results: Nineteen patients were included in the primary resistance group, and forty-three patients were included in the control group. The IBI was significantly higher in the resistant group compared to the control group (P<0.01). The area under the curve for the IBI was 0.82, indicating a strong predictive value. Multivariate analysis identified the IBI as an independent predictor of primary resistance (P=0.014). Conclusions The baseline IBI holds promise as a predictor of primary resistance to combined ICIs and chemotherapy in patients with HER-2-negative advanced gastric cancer.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.

Abstract Blood donation institutions mainly rely on manual identification for pre-donation health screening of blood donors. To further ensure the safety of blood donation and minimize the participation of unqualified donors, Ningbo Central Blood Station developed and launched a pre-blood donation health screening software as a supplement to the manual identification in May 2023. The software establishes preset rules based on the conditions of donors who are ineligible or temporarily ineligible to donate blood in Whole Blood and Component Donor Selection Requirements (GB 18467-2011), retrieves the health records of blood donors from the Ningbo National Health Information System and compares with the preset rules. When a preset rule is triggered, the medical examiner receives a warning. The pre-donation health screening software effectively enhances the capabilities of blood donation institutions in identifying unqualified donors. It is conducive to promoting the standardization of the pre-donation health screening process, the intelligence of blood donation services and blood management, and the establishment of a more scientific and efficient pre-donation health screening procedure.

Objective:To investigate the prevalence and mortality of dementia and assess the impact of geriatric syndromes (GS) on the risk for dementia and death in elderly population in Beijing.Methods:A cross-sectional survey was conducted in the elderly population aged ≥65 years and selected by a multi-stage sampling in Beijing during 2013-2015. Cognitive function was screened using the Chinese Revised Version of the Mini-Mental State Examination (MMSE). Then, neurological examination and psychiatric assessment were performed for those with the MMSE score lower than the cut-off value. The information about GS prevalence was also collected. The study also collected death records for all individuals from baseline until December 31, 2019. Based on the age and gender distribution from Beijing data of the 2010 Six th National Population Census, the dementia prevalence in the study population was directly standardized. Logistic regression analysis was used to evaluate the association of different forms of dementia with GS, and Cox proportional hazards regression model was used to estimate the hazard ratio ( HR) and 95% CI of death. Results:During 2013-2015, a total of 2 935 individuals completed dementia assessments, of which 167 were diagnosed with dementia. The standardized prevalence of dementia was 5.9% (95% CI: 5.0%-17.4%). The individuals with Alzheimer's disease (AD) and vascular dementia (VaD) accounted for 58.7% and 28.1% of total individuals with dementia, respectively. Aging, lower education level, urinary incontinence, and fall were risk factors for AD, while disability of activity of daily life dependence, hypertension, and stroke were found to be risk factors for VaD. After a median follow-up of 5.44 person-years, 399 deaths were recorded. The 5-year mortality risk was 2.87 (95% CI: 1.92-4.17) times and 4.93 (95% CI: 3.23-7.53) times higher for the elderly individuals with AD and VaD, respectively, compared to non-demented individuals. After adjusting for demographic, GS, and cardiovascular risk factors, the mortality risk in the elderly individuals with AD showed no significant difference compared with non-demented individuals ( HR=1.32, 95% CI: 0.89-1.97), while the mortality risk in those with VaD was 2.46 (95% CI: 1.49-4.05) times higher than that in non-demented individuals. Conclusions:The prevalence of dementia in Beijing increased significantly in the context of population aging, especially the prevalence of AD. The presence of GS increased the risks for AD and VaD, as well as the risk for death. Close attention needs to be paid to GS management in dementia prevention in elderly population.

Objective: To investigate the protective effect of vitamin D3 on alcoholic liver injury in mice. Methods: Forty mice were randomly divided into 4 groups : normal Control (Control) group , vitamin D3 (VitD3 ) group , alcohol model (EtOH) group and alcohol + vitamin D3 (EtOH + VitD3 ) group. The mice were fed with the DeCarlialcohol liquid diet to establish alcoholic liver injury model. Serum levels of alanine aminotransferase (ALT) , aspartate aminotransferase (AST) and liver index were detected. HE staining was used to observe the pathological changes of liver. The relative expression levels of tumor necrosis factor α (TNF⁃α ) , transforming growth factor β (TGF⁃β) , interleukin⁃6 (IL⁃6) and interleukin⁃1β (IL⁃1β) mRNA were detected by quantitative real⁃time PCR (qRT⁃PCR) . The expressions of nuclear factor⁃kappa B (NF⁃κB) p65 and NF⁃κB p50 in liver were detected by Western blot. Results: The serum ALT , AST vitality , liver index and hepatic TNF⁃α , TGF⁃ β , IL⁃6 and IL⁃1β mRNA in EtOH group were significantly higher than those in Control group. EtOH group disorganized hepatocyte and hepatic lobules boundary was not clear, and the hepatocytes showed apparent inflammatory cells infiltration of liver cells and fat cavitation. NF⁃κB p65 and NF⁃κB p50 protein expression increased significantly. Compared with EtOH group ,the serum ALT , AST vitality , liver index and hepatic TNF⁃α , TGF⁃ β , IL⁃6 and IL⁃1β mRNA in EtOH + VitD3 group decreased significantly. The pathological staining results showed that inflammatory cells infiltration and decrease in the number of fat vacuoles , and the liver cells returned to normal liver cell structure. At the same time the NF⁃κB p65 and NF⁃κB p50 protein expression level decreased significantly. Conclusion Vitamin D3 has a certain protective effect on alcohol⁃induced liver injury in mice , and its main mechanisms are related to the inhibition of NF⁃κB pathway and the reduction of inflammatory response.

Objective : To investigate the effect of platelet particles on the extent of intestinal inflammation and in⁃ testinal mucosal permeability in mice with dextran sodium sulfate induced colitis. Methods : The experiment was divided into four groups : normal control group ( n = 10 , drinking sterile distilled water + intraperitoneal injection of 0. 9% sodium chloride solution) , PMPs group ( n = 10 , drinking sterile distilled water + intraperitoneal injection of PMPs) , DSS model group ( n = 10 , drinking DSS solution + intraperitoneal injection of 0. 9% sodium chloride solution) , and experimental group ( n = 15 , drinking DSS solution + intraperitoneal injection of PMPs) . Peripheral blood⁃derived PMPs suspension was collected from inflammatory bowel disease ( IBD) patients. A colitis model was constructed in mice by allowing them to freely drink a 5% DSS solution for 1 week , followed by continuous intraperitoneal injection of PMPs for 7 days. Disease activity index (DAI) scores was recorded daily and the severity of intestinal inflammation with histopathological scores (HI) was assessed by HE staining of colon samples at the end of the experiment. Myeloperoxidase (MPO) , neutrophil elastase (NE) , citrullinated histone H3 (citH3) , and free DNA levels were measured in colon homogenate , observe intestinal mucosal structure by transmission electron microscopy , and intestinal permeability was tested using fluorescein isothiocyanate⁃dextran (FITC⁃D) . Results: Compared with the normal control group , the colonic mucosa of mice in the PMPs group showed edema , severe destruction of epithelial structure , extensive aggregation of inflammatory cells , and increased overall HI score (P < 0. 01) ; the levels of inflammatory factors such as IL⁃1β and TNF⁃α in colonic tissue homogenates of mice in the PMPs group increased (P < 0. 05) , and the expression of NETs increased (P < 0. 05) ; the plasma FITC⁃D level of mice in the PMPs group significantly increased (P < 0. 05) , and the permeability of intestinal mucosa increased. Compared with the DSS group , the experimental group mice had higher plasma FITC⁃D levels ( P < 0. 05 ) and more electron microscopic colonic epithelial damage. Conclusion PMPs induces NETs formation in mice , promotes colonic inflammation in mice , increases intestinal mucosal permeability and aggravates intestinal inflammation in mice with DSS colitis.
