Objective To investigate the diagnostic value of 4 novel inflammatory markers related to routine blood tests,namely neutrophil-to-lymphocyte ratio(NLR),red blood cell distribution width(RDW),hemoglobin-to-RDW ratio(HRR)and systemic immune-inflammation index(SII),in elderly patients with chronic cardiovascular disease(CVD)complicated with frailty.Methods Retrospectively analyze 110 patients with chronic stable CVD who were hospitalized in the cadre ward of cardiovascular medicine at the Air Force Characteristic Medical Center from January 2022 to June 2023.According to the assessment results of the Fried scale,they were divided into three groups:non-frailty group(Fried score=0,n=30),the pre-frailty group(Fried score 1 or 2,n=40)and frailty group(Fried score≥3,n=40).The differences in general information,the impairment rate of daily living activities,miniature nutritional assessment-short form(MNA-SF)scores,mini-mental state examination(MMSE)scores,and the indicators such as NLR,RDW,HRR,and SII among the three groups were compared.Spearman rank correlation was used to analyze the correlation between NLR,RDW,HRR,SII and frailty scores as well as each frailty indicator.Multivariate logistic regression analysis was performed to identify the independent risk factors for frailty in elderly patients with chronic CVD,and the receiver operating characteristic(ROC)curve was used to assess the clinical diagnostic value of NLR and HRR in elderly patients with chronic CVD complicated with frailty.Results Compared with non-frailty group and pre-frailty group,patients in frailty group were older,with higher impaired rates of daily living activities,NLR,RDW,and SII,and lower MNA-SF scores,MMSE scores,and HRR,and differences were statistically significant(P<0.05).Spearman rank correlation analysis showed that the frailty score was positively correlated with NLR(rs=0.354,P<0.001),and RDW(rs=0.448,P<0.001),negatively correlated with HRR(rs=-0.232,P=0.024),and had no significant correlation with SII(rs=0.144,P=0.167).Further analysis of the correlation between the above novel inflammatory markers and the 5 components of frailty showed that NLR was positively correlated with fatigue(rs=0.228,P=0.017),slowed walking speed(rs=0.299,P<0.001),and low physical function(rs=0.319,P<0.001);RDW was positively correlated with decreased grip strength(rs=0.321,P<0.001),slowed walking speed(rs=0.422,P<0.001),and low physical function(rs=0.246,P=0.001);and HRR was negatively correlated with slowed walking speed(rs=-0.230,P=0.025),and low physical function(rs=-0.299,P=0.003).Multivariate logistic regression analysis showed that MNA-SF score(OR=0.577,95%CI 0.342-0.973)was an independent protective factor for pre-frailty in elderly patients with chronic CVD(P<0.05);NLR(OR=7.866,95%CI 1.101-56.185)was an independent risk factor for frailty,while HRR(OR=0.344,95%CI 0.120-0.983)and MNA-SF score(OR=0.292,95%CI 0.146-0.580)were independent protective factors for frailty in elderly CVD patients(P<0.05).The area under the ROC curve of NLR and HRR for diagnosing frailty in elderly patients with chronic CVD were 0.778 and 0.749,respectively.Conclusion NLR and HRR have high clinical diagnostic value for frailty in elderly patients with chronic CVD,and are expected to become effective inflammatory markers for screening elderly patients with chronic CVD complicated with frailty.

With the rapid development of generative artificial intelligence(GAI)technologies,their widespread application in academic research and writing is continuously expanding the boundaries of sci-entific inquiry.However,this trend has also raised a series of ethical and regulatory challenges,inclu-ding issues related to authorship,content authenticity,citation accuracy,and accountability.In light of the growing involvement of AI in generating academic content,establishing an open,controllable,and trustworthy ethical governance framework has become a key task for safeguarding research integrity and maintaining trust within the academic community.This expert consensus outlines ethical requirements across key stages of AI-assisted academic writing-including topic selection,data management,citation practices,and authorship attribution.It aims to clarify the boundaries and ethical obligations surrounding AI use in academic writing,ensuring that technological tools enhance efficiency without compromising in-tegrity.The goal is to provide guidance and institutional support for building a responsible and sustainable research ecosystem.

Objective To explore the anti-intestinal fibrosis mechanism of Dahuang Zhechong pill.Methods Based on the network pharmacology method,the traditional Chinese medicine systems pharmacology database and analysis platform,SwissTargetPrediction database and metabolomics technology was used.OmicsNet 2.0 platform combined with the findings of network pharmacology and metabolomics,and molecular simulation docking and molecular biology methods were used to study the mechanism of anti-intestinal fibrosis of Dahuang Zhechong pill.Results Dahuang Zhechong pill contains 142 potential active ingredients and 855 anti-intestinal fibrosis targets.The 10 core ingredients(quercetin,acacetin,oroxylin a,kaempferol,moslosooflavone,panicolin,etc.)may play a role in regulating lipid metabolism and atherosclerosis,EGFR tyrosine kinase inhibitor resistance,HIF-1 signaling pathway,TNF signaling pathway and IL-17 signaling pathway.Metabolomics results showed that 59 endogenous substances(oxaloacetic acid,ethylthioisonicamide,6-benzylaminopurine,tyrosine and cortisol,etc.)may be the key metabolites of this drug against intestinal fibrosis.Central carbon metabolism,TCA cycle and amino acid metabolism were the key mechanisms,EGFR,AKT1,MAPK1,PTPN11,CASP3,PPARG,MET and PDGFRB may be the core targets.Dahuang Zhechong pill could significantly improve the levels of colorectal edema,inflammatory factors,inflammatory cell infiltration,collagen fiber deposition and α-SMA expression in mice with intestinal fibrosis,reduce the expression levels of pro-inflammatory factors IL-17 and IL-23 in serum,and increase the level of anti-inflammatory factor IL-10.Molecular dynamics simulations demonstrated stable conformational binding between core active ingredients and key targets.Conclusion Dahuang Zhechong pill may regulate EGFR/AKT1/MAPK mediated metabolism-inflammation interaction network through flavonoid components,and can improve intestinal fibrosis in multiple dimensions through molecular validation.

Aim To investigate the molecular mecha-nisms of the Wenyang Huazhuo Tongluo formula in in-hibiting endothelial-to-mesenchymal transition(En-doMT)of pulmonary microvascular endothelial cells and improving pulmonary microvascular injury in sys-temic sclerosis(SSc).Methods Pulmonary micro-vascular endothelial cells were cultured with serum from SSc patients to establish SSc pulmonary microvas-cular endothelial cells.A hypoxia model was estab-lished in SSc pulmonary microvascular endothelial cells using liquid paraffin sealing,and the cells were treated with the Wenyang Huazhuo Tongluo formula or HIF-1a inhibitor KC7F2.Western blot was used to detect the protein expression levels of VE-cadherin,CD31,vimen-tin,HIF-1α,Foxm1,smad3,Tie-1,and vWF.ELISA was used to measure the concentrations of E-selectin and ICAM-1 in cell culture medium.The luciferase re-porter gene system was used to detect the promoter ac-tivity of the Foxm1 gene.Results Compared to the control group,the levels of VE-cadherin,CD31,HIF-1α,Foxm1,smad3,Tie-1,and vWF significantly de-creased under hypoxic condition,while the levels of vi-mentin,E-selectin,and ICAM-1 significantly in-creased.In addition,the cell morphology exhibited a distinct"spindle-like"myoblast morphology.Treat-ment with the Wenyang Huazhuo Tongluo formula or KC7F2 reversed these changes in protein expression levels and cell morphology induced by hypoxia.Con-clusion The Wenyang Huazhuo Tongluo formula im-proves pulmonary microvascular injury in SSc by inhib-iting the HIF-1a/Foxm1/smad3 pathway-mediated En-doMT of pulmonary microvascular endothelial cells.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Abstract: Objective　To analyze the influencing factors of mother-to-child transmission of hepatitis B virus after combined immunological blockade, and to evaluate the effect of mother-to-child blockade, and to provide a basis for health policies and health interventions for preventing mother-to-child blockade of hepatitis B virus. Methods A total of 11 363 pairs of HBsAg positive pregnant women and their infants aged 7-12 months in Hainan Province from 2015 to 2020 were included in the study. The general situation, the situation of health care and delivery in this pregnancy and perinatal period, the detection of hepatitis B markers, the situation of antiviral therapy, the general situation of mother and infant during delivery and the implementation of blockade measures for mother-to-child transmission of hepatitis B were collected and analyzed. Results Among the 11 363 pairs of HBsAg positive pregnant women and their infants delivered in hospitals in Hainan province from 2015 to 2020, the positive rate of HBsAg in children at 7-12 months after birth was 1.47 %, and the difference in HBsAg positive rate of infants born in different years was not statistically significant (P>0.05). There were no significant differences in the positive rate of HBsAg among children born to pregnant women with different nationalities, educational levels, occupations, delivery modes, delivery places, obstetric operations and perineal laceration, abnormal perinatal period, children with different genders and premature delivery and perinatal (all P<0.05). There was significant difference in HBsAg positive rate among infants born to pregnant women of different ages, the positive rate of HBsAg of infants born to young pregnant women was higher than that of older pregnant women (P<0.05). The rate of antiviral therapy was low in HBeAg positive pregnant women, and the positive rate of HBsAg in their infants was 2.54%, which was higher than 0.83% in HBeAg negative pregnant women (P<0.05). Conclusions Combined immunological blockade with hepatitis B vaccine and hepatitis B immunoglobulin can effectively prevent the mother-to-child transmission of HBV. HBsAg-positive women can give birth at the right age, and HBeAg-positive pregnant women can be treated with antiviral therapy to block mother-to-child transmission, providing the important basis for the formulation of hepatitis B prevention and control strategies and measures.

OBJECTIVE: To explore the risk and location of multiple malignancies in patients with hematologic malignancies who were followed up for 9 years in Jiangsu Province Hospital and to evaluate the impact of the second primary malignancy on survival of patients. METHODS: The incidence and survival of multiple malignancies in 7 921 patients with hematologic malignancies from 2009 to 2017 were analyzed retrospectively. RESULTS: A total of 180 (2.3%, 180/7 921) patients developed second malignancy, of whom 58 patients were diagnosed with hematologic malignancies as the first primary malignancy, and 98 patients developed hematologic malignancies as second primary malignancy, and the other 24 cases were diagnosed with the second malignancy within 6 months after the first primary malignancy was diagnosed, which was difined as multiple malignancies occurring simultaneously. In 180 patients, 18 cases developed two hematologic malignancies successively, and 11 patients developed more than 3 primary cancers (among them, 2 female patients were diagnosed with 4 primary cancers). Patients with lymphoma and multiple myeloma (MM) as the second primary malignancy had poorer survival than patients with lymphoma and MM as the first primary malignancy. Patients with chronic myeloid leukemia as the second primary malignancy were also associated with inferior overall survival. CONCLUSION In this study, 2.3% of hematologic malignancy patients had multiple mali-gnancies, lymphoma and MM as the second primary malignancy had poor survival.
