And sex hormone level disorder has became a hot research topic in the pathogenesis of acne. Studies show that the biological clock disorder can result in the disorder of sex hormone levels which causes or aggravates acne. Biological clock disorder coincides naturally with "sleep rhythm disorder" in Traditional Chinese Medicine(TCM). In this paper, we will discuss the modern medical mechanism of the biological clock disorder resulting in acne from the angle of sex hormones, and analyze the TCM pathogenesis of the disease caused by the disorder of the biological clock.展开更多

TCM holds that the damp from the dysfunction of spleen, kidney and liver is the causative factor of complications of diabetes. This is similar to the mechanism of ROS resulting in angiopathic complications of diabetes. When the angiopathic complications of type II diabetes mellitus (T2DM) are differentiated as caused by turbid damp in TCM can be explained as ROS. Since the obstruction of pathogenic damp in channels and collaterals is said to be the main pathogenesis, the treating principle should be dissolving the damp to remove the obstruction.展开更多

This review systematically discusses strategies and progress in the construction of cardiac organoids, categorizing them into three main types:cardiac spheroids, self-organizing/assembloid organoids, and organoid-on-a-chip systems. This review uniquely integrates the advances in vascularization, organ-on-chip design, and environmental cardiotoxicity modeling within cardiac organoid platforms, offering a critical synthesis that is absent in the literature. In the context of escalating environmental threats to cardiovascular health, there is an urgent need for physiologically relevant models to accurately identify cardiac toxicants and elucidate their underlying mechanisms of action. This review highlights advances in cardiac organoid applications for disease modeling-including congenital heart defects and acquired cardiovascular diseases-drug development, toxicity screening, and the study of environmentally induced cardiovascular pathogenesis. In addition, it critically examines ongoing challenges and underscores opportunities brought by bioengineering approaches. Finally, we propose future directions for developing standardized cardiac organoid platforms with clinical predictability, aiming to expand the utility of this technology across broader research applications.展开更多

The pathogenesis of VM is complex and involves multiple genetic and environmental factors. Recent studies have suggested that the pathogenesis of vestibular migraine may be associated with variations in the CACNA1A gene, which is an important gene target for controlling calcium ion channels. Such variations may further affect the functions of the vestibular nervous system, thereby causing a series of vestibular nervous system-related symptoms. This article will summarize the genetic association studies of vestibular migraine, vestibular function studies, and research on how to establish relevant animal models to illustrate the possible association between CACNA1A variations and the pathogenesis of VM, providing new ideas for clarifying the pathogenesis of VM.展开更多

文摘Excess production of reactive oxygen species (ROS) of mitochondrion mediated by hyperglycemia is the common pathogenesis of angiopathic complications of diabetes. TCM holds that the damp from the dysfunction of spleen, kidney and liver is the causative factor of complications of diabetes. This is similar to the mechanism of ROS resulting in angiopathic complications of diabetes. When the angiopathic complications of type II diabetes mellitus (T2DM) are differentiated as caused by turbid damp in TCM can be explained as ROS. Since the obstruction of pathogenic damp in channels and collaterals is said to be the main pathogenesis, the treating principle should be dissolving the damp to remove the obstruction.

文摘The misfolding,aggregation,and deposition of alpha-synuclein into Lewy bodies are pivotal events that trigger pathological changes in Parkinson's disease.Extracellular vesicles are nanosized lipidbilayer vesicles secreted by cells that play a crucial role in intercellular communication due to their diverse cargo.Among these,brain-derived extracellular vesicles,which are secreted by various brain cells such as neurons,glial cells,and Schwann cells,have garnered increasing attention.They serve as a promising tool for elucidating Parkinson's disease pathogenesis and for advancing diagnostic and therapeutic strategies.This review highlights the recent advancements in our understanding of brain-derived extracellular vesicles released into the blood and their role in the pathogenesis of Parkinson's disease,with specific emphasis on their involvement in the aggregation and spread of alpha-synuclein.Brain-derived extracellular vesicles contribute to disease progression through multiple mechanisms,including autophagy-lysosome dysfunction,neuroinflammation,and oxidative stress,collectively driving neurodegeneration in Parkinson's disease.Their application in Parkinson's disease diagnosis is a primary focus of this review.Recent studies have demonstrated that brainderived extracellular vesicles can be isolated from peripheral blood samples,as they carryα-synuclein and other key biomarkers such as DJ-1 and various micro RNAs.These findings highlight the potential of brain-derived extracellular vesicles,not only for the early diagnosis of Parkinson's disease but also for disease progression monitoring and differential diagnosis.Additionally,an overview of explorations into the potential therapeutic applications of brain-derived extracellular vesicles for Parkinson's disease is provided.Therapeutic strategies targeting brain-derived extracellular vesicles involve modulating the release and uptake of pathological alpha-synuclein-containing brain-derived extracellular vesicles to inhibit the spread of the protein.Moreover,brain-derived extracellular vesicles show immense promise as therapeutic delivery vehicles capable of transporting drugs into the central nervous system.Importantly,brain-derived extracellular vesicles also play a crucial role in neural regeneration by promoting neuronal protection,supporting axonal regeneration,and facilitating myelin repair,further enhancing their therapeutic potential in Parkinson's disease and other neurological disorders.Further clarification is needed of the methods for identifying and extracting brain-derived extracellular vesicles,and large-scale cohort studies are necessary to validate the accuracy and specificity of these biomarkers.Future research should focus on systematically elucidating the unique mechanistic roles of brain-derived extracellular vesicles,as well as their distinct advantages in the clinical translation of methods for early detection and therapeutic development.

文摘Epilepsy is a severe,relapsing,and multifactorial neurological disorder.Studies regarding the accurate diagnosis,prognosis,and in-depth pathogenesis are crucial for the precise and effective treatment of epilepsy.The pathogenesis of epilepsy is complex and involves alterations in variables such as gene expression,protein expression,ion channel activity,energy metabolites,and gut microbiota composition.Satisfactory results are lacking for conventional treatments for epilepsy.Surgical resection of lesions,drug therapy,and non-drug interventions are mainly used in clinical practice to treat pain associated with epilepsy.Non-pharmacological treatments,such as a ketogenic diet,gene therapy for nerve regeneration,and neural regulation,are currently areas of research focus.This review provides a comprehensive overview of the pathogenesis,diagnostic methods,and treatments of epilepsy.It also elaborates on the theoretical basis,treatment modes,and effects of invasive nerve stimulation in neurotherapy,including percutaneous vagus nerve stimulation,deep brain electrical stimulation,repetitive nerve electrical stimulation,in addition to non-invasive transcranial magnetic stimulation and transcranial direct current stimulation.Numerous studies have shown that electromagnetic stimulation-mediated neuromodulation therapy can markedly improve neurological function and reduce the frequency of epileptic seizures.Additionally,many new technologies for the diagnosis and treatment of epilepsy are being explored.However,current research is mainly focused on analyzing patients’clinical manifestations and exploring relevant diagnostic and treatment methods to study the pathogenesis at a molecular level,which has led to a lack of consensus regarding the mechanisms related to the disease.

文摘Alzheimer's disease poses a significant global health challenge owing to the progressive cognitive decline of patients and absence of curative treatments.The current therapeutic strategies,primarily based on cholinesterase inhibitors and N-methyl-Daspartate receptor antagonists,offer limited symptomatic relief without halting disease progression,highlighting an urgent need for novel research directions that address the key mechanisms underlying Alzheimer's disease.Recent studies have provided insights into the critical role of glycolysis,a fundamental energy metabolism pathway in the brain,in the pathogenesis of Alzheimer's disease.Alterations in glycolytic processes within neurons and glial cells,including microglia,astrocytes,and oligodendrocytes,have been identified as significant contributors to the pathological landscape of Alzheimer's disease.Glycolytic changes impact neuronal health and function,thus offering promising targets for therapeutic intervention.The purpose of this review is to consolidate current knowledge on the modifications in glycolysis associated with Alzheimer's disease and explore the mechanisms by which these abnormalities contribute to disease onset and progression.Comprehensive focus on the pathways through which glycolytic dysfunction influences Alzheimer's disease pathology should provide insights into potential therapeutic targets and strategies that pave the way for groundbreaking treatments,emphasizing the importance of understanding metabolic processes in the quest for clarification and management of Alzheimer's disease.

文摘Gestational diabetes mellitus(GDM)refers to varying degrees of abnormal glucose metabolism that occur during pregnancy and excludes patients pre-viously diagnosed with diabetes.GDM is a unique among the four subtypes of diabetes classified by the international World Health Organization standards.Although GDM patients constitute a small proportion of the total number of diabetes cases,the incidence of GDM has risen significantly over the past decade,posing substantial risk to pregnant women and infants.Therefore,it warrants considerable attention.The pathogenesis of GDM is generally considered to resemble that of type II diabetes,though it may have distinct characteristics.Analyzing blood biochemical proteins in the context of GDM can help elucidate its pathogenesis,thereby facilitating more effective prevention and management strategies.This article reviews this critical clinical issue to enhance the medical community's sufficient understanding of GDM.
文摘Inflammatory bowel disease(IBD)is a chronic inflammatory illness of the intes-tine.While the mechanism underlying the pathogenesis of IBD is not fully under-stood,it is believed that a complex combination of host immunological response,environmental exposure,particularly the gut microbiota,and genetic suscept-ibility represents the major determinants.The gut virome is a group of viruses found in great frequency in the gastrointestinal tract of humans.The gut virome varies greatly among individuals and is influenced by factors including lifestyle,diet,health and disease conditions,geography,and urbanization.The majority of research has focused on the significance of gut bacteria in the progression of IBD,although viral populations represent an important component of the microbiome.We conducted this review to highlight the viral communities in the gut and their expected roles in the etiopathogenesis of IBD regarding published research to date.
文摘Vestibular Migraine (VM) is a common neurological disorder characterized by recurrent episodes of vertigo and migraine symptoms. The pathogenesis of VM is complex and involves multiple genetic and environmental factors. Recent studies have suggested that the pathogenesis of vestibular migraine may be associated with variations in the CACNA1A gene, which is an important gene target for controlling calcium ion channels. Such variations may further affect the functions of the vestibular nervous system, thereby causing a series of vestibular nervous system-related symptoms. This article will summarize the genetic association studies of vestibular migraine, vestibular function studies, and research on how to establish relevant animal models to illustrate the possible association between CACNA1A variations and the pathogenesis of VM, providing new ideas for clarifying the pathogenesis of VM.

文摘Adenosine triphosphate(ATP)-binding cassette(ABC)transporter systems are divided into importers and exporters that facilitate the movement of diverse substrate molecules across the lipid bilayer,against the concentration gradient.These transporters comprise two highly conserved nucleotide-binding domains(NBDs)and two transmembrane domains(TMDs).Unlike ABC exporters,prokaryotic ABC importers require an additional substrate-binding protein(SBP)as a recognition site for specific substrate translocation.The discovery of a large number of ABC systems in bacterial pathogens revealed that these transporters are crucial for the establishment of bacterial infections.The existing literature has highlighted the roles of ABC transporters in bacterial growth,pathogenesis,and virulence.These roles include importing essential nutrients required for a variety of cellular processes and exporting outer membrane-associated virulence factors and antimicrobial substances.This review outlines the general structures and classification of ABC systems to provide a comprehensive view of the activities and roles of ABC transporters associated with bacterial virulence and pathogenesis during infection.
