Dry eye disease is a chronic ocular surface disorder of multifactorial origin, characterized by a loss of tear film homeostasis and associated with a range of ocular discomfort symptoms. Growing evidence underscores a significant bidirectional relationship between dry eye and depression: individuals with dry eye disease exhibit a higher prevalence of depressive disorders, and conversely, those diagnosed with depression demonstrate an increased susceptibility to developing dry eye. This interplay is mediated through several pathophysiological pathways, such as chronic inflammation, cerebral functional alterations, gut microbiome dysregulation, and sleep disturbances, which may collectively sustain a vicious cycle. The use of antidepressant therapy introduces further complexity, exerting heterogeneous effects on dry eye—some agents may offer symptomatic relief, whereas others can aggravate ocular surface impairment. The mechanisms responsible for these differential outcomes remain incompletely elucidated and merit further investigation. This review systematically consolidates epidemiological data on the dry eye-depression link, examines potential shared pathological mechanisms, and evaluates current therapeutic options. We propose an integrated management approach that combines conventional dry eye treatments, such as traditional Chinese medicine, electroacupuncture, physical activity and antidepressants—a multimodal strategy that may yield synergistic benefits in alleviating both ocular and affective symptoms, thereby improving overall quality of life. Moving forward, research should focus on deciphering the underlying mechanistic pathways and facilitating the translation of these insights into clinical practice to inform targeted, combined treatment regimens for patients with dry eye and depression.

Objective To investigate the relationship between the comorbidity of dyslipidemia, hypertension and diabetes and lifestyle of adult residents in Hebei Province in 2018, and to provide reference for the development of chronic diseases prevention measures. Methods Using data from the surveillance of chronic diseases and their risk factors among adults in Hebei in 2018, 7 711 permanent residents aged ≥18 years were selected as the research subjects. Multivariate logistic regression analysis was used to analyze the relationship between the comorbidity of dyslipidemia, hypertension, and diabetes and lifestyle in adult residents. Results A total of 7 711 subjects aged ≥18 years were included in 2018. The comorbidity rates of hypertension and dyslipidemia, diabetes and dyslipidemia, and hypertension and diabetes were 16.88%, 7.91%, and 8.13%, respectively. The comorbidity rate of hypertension, diabetes, and dyslipidemia was 22.65%. These comorbidity rates increased with age and BMI. Multivariate logistic regression results showed that male, age, overweight/obesity, physical inactivity, daily sedentary behavior time ≥5 hours, and sleep problems were risk factors for the comorbidity of the "three highs". Conclusion The prevalence of the "three highs" comorbidities is relatively high in Hebei Province, and there are multiple common risk factors. Maintaining a healthy lifestyle and implementing comprehensive prevention and control measures are the key to improving the health level of residents.

BACKGROUND:Coptis chinensis can clear heat,dry dampness,relieve fire,and detoxify.Coptis chinensis and its components have a significant protective effect on cerebral ischemia.The action mechanism of anti-cerebral ischemia of Coptidis Rhizoma Alkaloids was explored based on network pharmacology and transcriptome sequencing. OBJECTIVE:Based on the study of the protective effects of Coptidis Rhizoma Alkaloids on cerebral ischemia of rats,the action mechanism of Coptidis Rhizoma Alkaloids intervention in cerebral ischemia was investigated by using network pharmacology and transcriptome sequencing technology. METHODS:The SD rats were randomly divided into sham operation group,ischemia/reperfusion group,positive drug group,and Coptidis Rhizoma Alkaloids group.The ischemia/reperfusion model of middle cerebral artery occlusion was prepared by modified thread method in the latter three groups.No thread was inserted and the other operations were the same in the sham operation group.TTC staining,Longa 5 neurological deficient score,hematoxylin and eosin staining,and Nissl staining were used to evaluate the protective effect of Coptidis Rhizoma Alkaloids on ischemia/reperfusion model rats.Transcriptome sequencing was performed on the brain tissues of rats in sham operation group,ischemia/reperfusion group,and Coptidis Rhizoma Alkaloids group.Differentially expressed genes,gene Ontology analysis,Kyoto encyclopedia of genes and genomes analysis,and Correlation Analysis of Transcriptomics and Network Pharmacology were used to elucidate the effect of Coptidis Rhizoma Alkaloids on cerebral ischemia.Finally,ELISA and immunofluorescence staining were used to verify the key targets of Coptidis Rhizoma Alkaloids in the intervention of cerebral ischemia. RESULTS AND CONCLUSION:(1)Coptidis Rhizoma Alkaloids treatment decreased the Longa 5 neurological deficit scores and cerebral infarction area of ischemia/reperfusion model rats,increased the number of neurons and Nissl bodies.(2)Differentially expressed gene after Coptidis Rhizoma Alkaloids treatment analyzed by functional enrichment analysis of gene ontology includes biological processes such as inflammatory reaction and positive regulation of mitogen-activated protein kinase cascade.The enrichment analysis of Kyoto gene and genome encyclopedia analysis pathway mainly involves interleukin-17 signaling pathway,neuroactive ligand-receptor interaction,cyclic adenosine-3′,5′-mconophosphate signaling pathway and so on.(3)Analysis of transcriptomics showed that the main genes regulated by Coptidis Rhizoma Alkaloids were prostaglandin endoperoxide synthase 2,brain derived neurotrophic factor,and transient receptor potential A1.(4)Network pharmacology analysis revealed that nine components in Coptidis Rhizoma Alkaloids may exert their effects by associating with 87 targets related to prostaglandin endoperoxide synthase 2,brain derived neurotrophic factor,and transient receptor potential A1.(5)ELISA and immunofluorescence staining results further confirmed that Coptidis Rhizoma Alkaloids regulated the expression of prostaglandin endoperoxide synthase 2,brain derived neurotrophic factor,and transient receptor potential A1.(6)It is concluded that Coptidis Rhizoma Alkaloids treatment can significantly improve the injury in ischemia/reperfusion model rats,possibly by regulating prostaglandin endoperoxide synthase 2,brain derived neurotrophic factor,and transient receptor potential A1.

Basic information, disease status and antiviral treatment conditions of the infected individuals were collected through questionnaires, specimen collection and laboratory tests. Univariate and multivariate logistic regression were used to analyze the related factors of the antiviral treatment rate of those who met the indications for hepatitis B antiviral treatment.Results:The median age ( Q1, Q3) of subjects was 56 (48, 66) years old, among which 436 (50.4%) were males. There were 712 (82.2%) individuals who met the indications for hepatitis B antiviral treatment, and 110 individuals received antiviral treatment with a rate of 15.5%. Multivariate logistic regression analysis showed that compared with males, families with an average monthly income per capita of <1 000 yuan, no alcohol consumption, no smoking, and a family history of HBV infection, females ( OR=4.66, 95% CI: 2.88-7.53), families with an average monthly income per capita of 1 000-1 999 yuan ( OR=1.64, 95% CI: 1.00-2.68) and ≥2 000 yuan ( OR=2.78, 95% CI: 1.54-5.03), alcohol consumption ( OR=6.42, 95% CI: 2.80-14.7), smoking ( OR=1.98, 95% CI: 1.04-3.77), and no family history of HBV infection ( OR=1.90, 95% CI: 1.16-3.09) had a lower antiviral treatment rate for chronic HBV infection. Conclusion:The antiviral treatment rate of chronic HBV-infected individuals in rural communities of Zhangqiu District, Jinan City is low, and the related factors are female, high monthly income per capita, alcohol consumption, smoking, and no family history of HBV infection.

Aim To explore the effect and mechanism of annexin A1 mimic peptide Ac2-26 on ferroptosis in hu-man umbilical vein endothelial cells(HUVEC).Methods Induction of HUVEC ferroptosis was achieved by the clas-sical ferroptosis agonist RSL3,with subsequent intervention by the annexin A1 mimtic peptide Ac2-26.The cell number and viability were detected by CCK-8 kit,the levels of malondialdehyde(MDA)and glutathione(GSH)were detected by ELISA,the expression of ferroptosis-related molecules and adhesion molecules was detected by Western blot,the lipid re-active oxygen species(ROS)levels were detected by C11-BODIPY fluorescent probe,and the mitochondrial reactive oxy-gen species(mtROS)levels were detected by MitoSOX probe.FeRhoNOX-1 fluorescent probe was used to detect intra-cellular Fe2+content,perspective microscopy was used to observe mitochondrial morphology,JC-1 fluorescent probe was used to detect mitochondrial membrane potential,kit was used to detect ATP levels,the Scratch assay was used to detect cell migration ability,and nitrate reductase assay was used to detect nitric oxide(NO)level.Results Ac2-26 inhibi-ted RSL3-induced decrease in HUVEC viability,up-regulated the expression of suppressor of ferroptosis proteolytic carrier family 7 member 11(SLC7A11),GPX4,and ferritin heavy chain 1(FTH1),increased the GSH content,decreased the MDA content,reduced the generation of intracellular lipid ROS,and decreased the intracellular Fe2+aggregation(P＜0.05 or P＜0.01);Ac2-26 inhibited RSL3-induced damage to HUVEC mitochondrial morphology and function,up-regulated ATP content(P＜0.05)and mitochondrial membrane potential(P＜0.001);Ac2-26 inhibited RSL3-induced decrease in HUVEC migratory ability,up-regulated NO levels,inhibited intercellular adhesion molecule-1(ICAM-1)and interleukin-1β(IL-1β)protein expression(P＜0.05 or P＜0.01).Conclusion Ac2-26 inhibits RSL3-induced ferroptosis in HUVEC and maintains mitochondrial morphology and function,as well as HUVEC function.

To verify whether the two B-cell epitopes Pep1 and Pep4 in the FAdV-4 WZ fiber can be used as candidate epitopes for multivalent epitope vaccines,epitopes Pep1 and Pep4 were tandemly linked with the chicken infectious bronchitis virus strain M41 S1 protein gene in different patterns,and a recombinant fusion plasmid was constructed and expressed in E.coli BL21(DE3).It was confirmed by Western blot and ELISA tests that all four expressed fusion proteins reacted specific-ally with anti-M41 whole virus serum and WZ strain anti-Fiber 2-knob protein serum.After purifi-cation and immunization of BALB/c mice,specific antibodies against the peptide epitopes were de-tected in mouse sera.The results showed that the Pep4 epitope induced a stronger immune re-sponse than the Pep1 epitope.When Pep1 was connected with the amino and carboxyl termini of the fusion protein,respectively,both resulted in the production of the same level of anti-Pep1 anti-bodies in the immunized animals,whereas when Pep4 was connected with the carboxyl terminus of the fusion protein,the immunized animals produced a higher level of anti-Pep4-specific antibodies.This research indicates that the B cell epitopes Pep1 and Pep4 of the reactive WZ strain Fiber 2,when conjugated with proteins to form fusion proteins,can enhance the immunogenicity of Pep1 and Pep4 without affecting the antigenicity of the carrier protein.This study provides technical support and serves as a reference for the design and development of a multivalent epitope vaccine for FAdV-4.

The results of multivariate analysis showed that the daily total static behavior time ( OR=1.07, 95% CI: 1.04-1.09), living in rural area ( OR=1.50, 95% CI: 1.14-1.97), coal use ( OR=1.37, 95% CI: 1.16-1.61), coal gas/liquefied gas/natural gas/biogas use ( OR=2.92, 95% CI: 2.40-3.54) and solar energy/electricity use ( OR=1.75, 95% CI: 1.36-2.25), insufficient fruit intake ( OR=1.39, 95% CI: 1.06-1.83), insufficient physical activity ( OR=1.35, 95% CI: 1.11-1.64), suffering from hypertension ( OR=1.80, 95% CI: 1.44-2.24) and suffering from diabetes ( OR=1.77, 95% CI: 1.27-2.45) were risk factors for CKD in adults in Hebei. High education level ( OR=0.41, 95% CI: 0.19-0.91), excessive drinking ( OR=0.53, 95% CI: 0.28-0.99), central obesity ( OR=0.75, 95% CI: 0.58-0.97), history of allergic diseases ( OR=0.44, 95% CI: 0.27-0.72) were protective factors for CKD. Conclusions:The prevalence of CKD in adults in Hebei was relatively high, especially in those who had too long average daily static behavior, lived in rural area, used coal, gas/liquefied gas/natural gas/biogas, solar energy/electricity, had inadequate intake of fruits, lacked physical activity and suffered from hypertension and diabetes. It is necessary to pay attention to the early prevention and treatment of CKD, strengthen the health education about healthy lifestyle and improve the management of patients with chronic disease, such as hypertension and diabetes, to further reduce the risk for CKD.
