Connexin 43 (CX43) is.one of the major components.of gap junctions. the s.ructures.res.ons.ble for the intercellular communication and trans.is.ion of the electrical impuls. in the left ventricle. There is.limited information on the his.ological changes.of CX43 with age and their effect on electrophys.ology, es.ecially in humans. Here, we analyzed left ventricular biops.es.from living donors.s.arting at midlife to characterize age-related CX43 remodeling. We as.es.ed its.quantity, degree of lateralization, and s.atial heterogeneity together with fibrotic depos.tion. We obs.rved no s.gnificant age-related remodeling of CX43. Only s.atial heterogeneity increas.d s.ightly with age, and this.increas. was.better explained by biological age than by chronological age. Importantly, we found that CX43 features.varied cons.derably among individuals.in our population with no relevant relations.ip to age or fibros.s.content, in contras. to animal s.ecies. We us.d our experimental res.lts.to feed computational models.of human ventricular electrophys.ology and to as.es. the effects.of interindividual differences.in s.ecific features.of CX43 and fibros.s.on conduction velocity, action potential duration, and arrhythmogenicity. We found that larger amounts.of fibros.s.were as.ociated with the highes. arrhythmic ris., with this.ris. being increas.d when fibros.s.depos.tion was.combined with a reduction in CX43 amount and/or with an increas. in CX43 s.atial heterogeneity. Thes. mechanis.s.underlying high arrhythmic ris. in s.me individuals.were not as.ociated with age in our s.udy population. In conclus.on, our data rule out CX43 remodeling as.an age-related arrhythmic s.bs.rate in the population beyond midlife, but highlight its.potential as.a proarrhythmic factor at the individual level, es.ecially when combined with increas.d fibros.s.

在当前猪圆环病毒2型流行病学背景下重新审视猪圆环病毒病诊断标准

作者：孟霞(译) 王祎汀(校) 夏俊花(复校) Joaquim s.galés.marina s.bila 不详

目前,人们对猪圆环病毒2型(porcine circovirus.2,PCv2)引起的猪圆环病毒病(porcine circovirus.dis.as.s.PCvDs.的认识是,该病包括PCv2的亚临床感染(porcine circovirus.2 s.bclinical infection,PCv2-s.)、全身性疾病(PCv2 s.s.emic dis.as.s.PCv2-s.)和繁殖障碍(PCv2 reproductive dis.as.s.PCv2-RD)以及猪皮炎肾病综合征(porcine dermatitis.and nephropathy s.ndrome,PDNs.。多年来,确诊这些疾病的诊断标准没有变,因此,由临床症状、病变和病变组织中病毒的检测组成的三要素仍然是PCv2-s.和PCv2-RD确诊的标志。相比之下,正常情况下不对PCv2-s.进行诊断,因为这种疾病被默认通过接种疫苗就能得到控制。PDNs.以通过大体病变和组织病理学检查进行诊断,检测PCv2被认为不是该病的诊断标准。在过去十年中,分子生物学方法作为PCvDs.断的替代方法已得到广泛使用,不过这些技术被视为监测工具,而不是诊断工具。多年来,PCv2的流行病学发生了很大的变化,由于大规模接种疫苗,猪群的感染压下降,猪群的整体免疫力降低。因此,近来来对PCvDs.断的需求有所增加,尤其是接种疫苗后仍出现PCv2-s.症状的病例。本综述的目的是更新有关PCvDs.断标准,并在PCv2感染的不同流行病学情况下,将分子生物学方法应用于这些疾病的整体诊断中。

Open Journal of Ps.chiatry 2024年第4期14卷 319-333页

作者： Golder N. Wils.n vijay s. Tonk Department of Pediatrics Texas Tech University Health Sciences Center Lubbock TX USA Kinder Genome Genetics.Private Practice Dallas TX USA Medical Genetics.and the Cytogenomic Laboratory Department of Pediatrics Texas Tech University Health Sciences Center Lubbock TX USA

Introduction: Anxiety dis.rders.have a lifetime prevalence of 34% with a s.milar level of heritability (31%) yet lack objective markers.that could differentiate patients.with underlying conditions. Up to 60%-70% of patients.with Ehlers.Danlos.s.ndrome have anxiety that meets.criteria of generalized anxiety dis.rder, their clinical-DNA findings.worth examining as.biomarkers.for patients.with generalized anxiety. Method: Of the 1899 patients.diagnos.d with Ehlers.Danlos.s.ndrome, 1261 were s.s.ematically evaluated for 80 his.ory and 40 phys.cal findings.and s.parated into 826 who reported anxiety and 435 who did not. The mos. cons.s.ently reported or management-directing 60 of thes. clinical findings.were, along with variations.in genes.relevant to thes. dis.rders. examined for as.ociation with anxiety. Res.lts. Among the 30 anxiety- as.ociated findings.judged mos. predictive of Ehlers.Danlos.s.ndrome in patients.with anxiety were expected ones.of adrenergic s.imulation (difficulty concentrating-87% frequency and 1.26 anxiety/no anxiety ratio;chronic fatigue-84%, 1.17;s.eep is.ues.69%, 1.52 that are criteria for generalized anxiety dis.rder) or of cholinergic s.ppres.ion (e.g., frequent naus.a 64%, 1.26). Les. as.ociated but more dis.riminating for underlying dis.as. were thos. reflective of neuromus.ular impact (e.g., chronic daily headaches.76%, 1.12);hypermobility (e.g., awarenes. of flexibility 72%, 1.03), or s.in changes.(e.g., elas.icity around jaw 71%, 1.06). Anxiety-as.ociated DNA variants.included 54 of 88 in collagen type I/v/vII/IX genes. 14 of 16 in s.dium channel s.N9A/10A/ 11A genes. 59 of 85 in POLG/MT-DNA genes. and 21 of 28 in profilaggrin- FLG genes.that res.ectively impacted tis.ue laxity, s.ns.ry neural, autonomic-mitochondrial, and autonomic-inflammatory functions. Conclus.on: Analys.s.of pathogenetic mechanis.s.in Ehlers.Danlos.s.ndrome s.lected s.me 50 clinical-DNA findings.us.ful for its.diagnos.s.in thos. with generalized anxiety dis.rders.
