文摘Inflammatory bowel disease(IBD),which includes Crohn’s disease(CD)and ulcerative colitis(UC),is a chronic disorder characterized by gastrointestinal inflammation.Cigarette smoke is a well-established risk factor for the development and exacerbation of CD while exerting a paradoxical protective effect against the onset of UC.The exact mechanisms by which cigarette smoke influences IBD,as well as the opposite effects in UC and CD,have long remained unexplained.Here,we demonstrated the detrimental impact of cigarette smoke on CD progression while highlighting its beneficial effects on UC,as evidenced by analyses of human sample data.Mouse models of CD and UC exposed to cigarette smoke presented phenotypes consistent with those observed in human disease.GPR15,previously reported to direct regulatory T(Treg)cell colon homing,was upregulated in the colon tissues of both chemically induced colitis models after smoke exposure.Importantly,Gpr15 deletion ameliorated smoke-induced CD while increasing UC severity in mice.Furthermore,our study revealed that cigarette smoke mediated GPR15 to amplify colonic T helper type 17(Th17)cell populations,thereby worsening the adverse effects of smoking on CD in mouse models.Moreover,cigarette smoke induced an increase in Treg cells through GPR15,which contributed to mitigating its impact on UC in mouse models.Moreover,in cigarette smoke-exposed CD and UC model mice,C57BL/6JGpt-Tg(human GPR15)transgenic mice presented phenotypes opposite those of Gpr15-deficient mice.Overall,our study offers mechanistic insights into the role of cigarette smokeinduced GPR15+T cells in mediating the divergent effects of smoking on UC and CD.

文摘Background:The risk for chronic kidney disease(CKD)is influenced by genetic predisposition,sex,and lifestyle.Previous research indicates that coffee is a potentially protective factor in CKD.The current study aims to investigate whether sex disparity exists in the coffee–CKD association,and whether genetic risk of CKD or genetic polymorphisms of caffeine metabolism affect this association.Methods:A total of 359,906 participants from the UK Biobank who were enrolled between 2006 and 2010 were included in this prospective cohort study,which aimed to estimate the hazard ratios for coffee intake and incident CKD using a Cox proportional hazard model.Allele scores of CKD and caffeine metabolism were additionally adjusted for in a subsample with qualified genetic data(n=255,343).Analyses stratified by genetic predisposition,comorbidities,and sex hormones were performed.Tests based on Bayesian model averaging were conducted to ascertain the robustness of the results.Results:Coffee was inversely associated with CKD in a dose-dependent manner.The effects of coffee did not differ across different strata of genetic risk for CKD,but were more evident among slower genetically predicted caffeine metabolizers.Significant sex disparity was observed(P value for interaction=0.013),in that coffee drinking was only associated with the risk reduction of CKD in females.Subgroup analysis revealed that testosterone and sex hormone-binding globulin(SHBG),but not estradiol,modified the coffee–CKD association.Conclusions:In addition to the overall inverse coffee–CKD association that was observed in the general population,we could also establish that a sex disparity existed,in that females were more likely to experience the benefit of the association.Testosterone and SHBG may partly account for the sex disparity.

文摘Background:Tyrosine phosphorylation of intracellular proteins is a posttranslational modification that plays a regulatory role in signal transduction during cellular events.Dephosphorylation of signal transduction proteins caused by protein tyrosine phosphatases(PTPs)contributed their role as a convergent node to mediate cross-talk between signaling pathways.In the context of cancer,PTP-mediated pathways have been identified as signaling hubs that enabled cancer cells to mitigate stress induced by clinical therapy.This is achieved by the promotion of constitutive activation of growth-stimulatory signaling pathways or modulation of the immune-suppressive tumor microenvironment.Preclinical evidences suggested that anticancer drugs will release their greatest therapeutic potency when combined with PTP inhibitors,reversing drug resistance that was responsible for clinical failures during cancer therapy.Areas covered:This review aimed to elaborate recent insights that supported the involvement of PTP-mediated pathways in the development of resistance to targeted therapy and immune-checkpoint therapy.Expert opinion:This review proposed the notion of PTP inhibition in anticancer combination therapy as a potential strategy in clinic to achieve long-term tumor regression.Ongoing clinical trials are currently underway to assess the safety and efficacy of combination therapy in advanced-stage tumors.

文摘Our study sought to investigate the blood flow pattern in the superior vena cava(SVC)of healthy adults and to describe the development and characteristics of the flow pattern using 4D flow magnetic resonance imaging(MRI).4D flow MRI data with full coverage of SVC and brachiocephalic veins(BVs)were acquired with a 3-Testa MRI in thirty healthy adults(age:28.70±9.09).Hemodynamic parameters in the SVC,including velocity,velocity vector,flow visualization(pathlines,streamlines),flow waveform and energy loss,were obtained with specialized commercial post-processing software based on 4D flow MRI data.This study found that:(1)The SVC has a pulsating flow waveform with double peaks.(2)Based on BVs flow of the SVC pathline visualization,flow patterns could be divided into three development types:twining(n=14),untwining(n=)and no helical flow(n=7).(3)With the decreasing blood velocity,helical flow areas tended to gradually extend.(4)There were no significant differences in most hemodynamic parameters among the three types.The exploration of the blood flow characteristics of normal SVC may be the first step for capturing pathogenic features before the patients develop symptoms with a certain positive significance.The potential physiological significance of these phenomena deserves more exploration in future studies.

文摘Background:This study aimed to explore the time-varying impact of COVID-19 on acute kidney disorders,including acute kidney injury and other acute kidney diseases.Methods:From the UK Biobank,10,121 participants with COVID-19 were matched with up to 3 historically unexposed controls by age,sex,Townsend deprivation index,and the status of hospitalization or receiving critical care.We investigated the association between COVID-19 and incidence of acute kidney disorders,within the ffrst 4 weeks after infection,using conditional and time-varying Cox proportional hazard regression.In addition,one-sample Mendelian randomization,utilizing the polygenic risk score for COVID-19 as an instrumental variable,was conducted to explore the potential causality of the association.Results:In the matched cohort study,we observed a signiffcant association between COVID-19 and acute kidney disorders predominantly within the ffrst 3 weeks.The impact of COVID-19 was time dependent,peaking in the second week(hazard ratio,12.77;95%conffdence interval,5.93 to 27.70)and decreasing by the fourth week(hazard ratio,2.28;95%conffdence interval,0.75 to 6.93).In subgroup analyses,only moderate to severe COVID-19 cases were associated with acute worsening of renal function in a time-dependent pattern.One-sample Mendelian randomization analyses further showed that COVID-19 might exert a“short-term”causal effect on the risk of acute kidney disorders,primarily conffned to the ffrst week after infection.Conclusions:The risk of acute kidney disorders following COVID-19 demonstrates a time-varying pattern.Hazard effects were observed only in patients with moderate or severe but not mild COVID-19.

文摘Whether associations between psychiatric disorders and hospitalization for cardiovascular diseases(CVDs)can be modified by disease susceptibility and the temporal pattern of these associated CVDs remain unknown.In our study,we conducted a matched cohort study of the UK Biobank including 44,430 patients with common psychiatric disorders(anxiety,depression,and stress-related disorders)between 1997 and 2019,together with 222,150 sex-,Townsend deprivation index-,and birth year-individually matched unexposed individuals.The hazard ratios(HRs)for CVD hospitalization associated with a prior psychiatric disorder were derived from Cox models,adjusted for multiple confounders.We then stratified the analyses by self-reported family history of CVD and CVD polygenic risk score(PRS)calculated based on summary statistics of independent genome-wide association studies.We further conducted disease trajectory analysis and visualized the temporal pattern of CVDs after common psychiatric disorders.During a mean follow-up of 12.28 years,we observed an elevated risk of CVD hospitalization among patients with psychiatric disorders,compared with matched unexposed individuals(hazard ratios[HRs]=1.20,95%confidence interval[CI]:1.18–1.23),especially during the first six months of follow-up(1.72[1.55–1.91]).The stratification analyses by family history of CVD and by CVD PRS obtained similar estimates between subgroups with different susceptibilities to CVD.We conducted trajectory analysis to visualize the temporal pattern of CVDs after common psychiatric disorders,identifying primary hypertension,acute myocardial infarction,and stroke as three main intermediate steps leading to further increased risk of other CVDs.In conclusion,the association between common psychiatric disorders and subsequent CVD hospitalization is not modified by predisposition to CVD.Hypertension,acute myocardial infarction,and stroke are three initial CVDs linking psychiatric disorders to other CVD sequelae,highlighting a need of timely interven-tion on these targets to prevent further CVD sequelae among all individuals with common psychiatric disorders.
