Nowadays, ...Environmental endocrine disrupting chemicals （EDCs）, commonly found in the environment, come from industry and agriculture, including pesticides, fungicides, insecticides, herbicides, and other chemicals. Nowadays, more and more EDCs were released into the environment. EDCs go into water body via atmosphere sedi-mentation, surface runoff, soil eluviation, etc., so water body becomes the main place for existing. In order to attract scientific and public attention worldwide and to prevent EDCs pol ution, in this study we reviewed the classification of EDCs and their concentrations in natural water bodies, drinking water sources and water plants, and the reproductive toxicity of EDCs to fish were reviewed. EDCs could disturb the endocrine system and make reproductive organs and reproduction abnor-mal, resulting in fertility descending, reproduction function damage, community quan-tity decrease and even species extinction. In addition, EDCs could disrupt the homeostasis maintained by hormones, which would result in defects of neural de-velopment and abnormalities of the endocrine and reproductive systems. The exact molecular mechanisms have not been completely reported, but researches have suggested that multiple mechanisms were involved in the action of EDCs. Although there have been researches on the biohazard of EDCs, there stil exist problems of weakness in fundamental researches, difficulties in recognizing and identifying EDCs and high cost, which restraint the knowledge on them.展开更多

文摘Suicide is defined as the act of a person attempting to take their own life by causing death.Suicide is a complex phenomenon that is influenced by a multitude of factors,including psychosocial,cultural,and religious aspects,as well as genetic,biochemical,and environmental factors.From a biochemical perspective,it is crucial to consider the communication between the endocrine,immune,and nervous systems when studying the etiology of suicide.Several pathologies involve the bidirectional communication between the peripheral activity and the central nervous system by the action of molecules such as cytokines,hormones,and neurotransmitters.These humoral signals,when present in optimal quantities,are responsible for maintaining physiological homeostasis,including mood states.Stress elevates the cortisol and proinflammatory cytokines levels and alter neurotransmitters balance,thereby increasing the risk of developing a psychiatric disorder and subsequently the risk of suicidal behavior.This review provides an integrative perspective about the neurochemical,immunological,and endocrinological disturbances associated with suicidal behavior,with a particular focus on those alterations that may serve as potential risk markers and/or indicators of the state preceding such a tragic act.
文摘Endocrine disorders frequently lead to metabolic disturbances that significantly affect liver function.Understanding the complex interplay between hormonal imbalances and liver dysfunction is essential for advancing targeted therapeutic strategies.This comprehensive review explores the pathophysiological mechanisms linking major endocrine disorders to liver disease,with a focus on the roles of the thyroid,parathyroid,pancreas,adrenal glands,and sex hormones.Thyroid dysfunction is associated with alterations in liver enzyme levels and metabolic regulation,often resulting in hepatic steatosis or cholestasis.Hyperparathyroidism and consequent hypercalcemia have been linked to hepatic calcifications.Insulin resistance,both hepatic and peripheral,contributes to excessive lipid accumulation in the liver,exacerbating steatotic changes.Adrenal gland disorders,particularly in the setting of chronic liver disease,impair cortisol metabolism and may worsen hepatic injury.Additionally,sex hormones such as estrogen and testosterone modulate the progression of liver fibrosis and influence the development of metabolic syndrome.The intricate relationship between endocrine and hepatic systems underscores the need for a multidisciplinary approach in the management of liver disease.Addressing underlying hormonal disturbances may enhance patient outcomes and prevent further hepatic deterioration.Future research should prioritize integrative therapeutic strategies that concurrently target endocrine and liver dysfunction.
文摘Transgender individuals often undergo gender-affirming hormonal therapy(GAHT)to align their physical characteristics with their gender identity,which introduces unique challenges in the management of critically ill patients.In the setting of critical illness,the interactions between GAHT and the body's endocrine response are complex.GAHT can influence the hypothalamic-pituitary-adrenal axis,sex hormone levels,and metabolic parameters,potentially complicating the clinical picture.For example,estrogen therapy in transgender women increases the risk of venous thromboembolism,which is further exacerbated by the immobility and hypercoagulable state often present in critically ill patients.Testosterone therapy in transgender men can lead to erythrocytosis,increasing the risk of thromboembolic events during critical illness.The potential for drug interactions,particularly with medications used in the intensive care unit,also requires careful consideration.Monitoring hormone levels and adjusting GAHT in the acute setting are crucial,although evidence-based guidelines are lacking.The need for individualized care and vigilant monitoring of endocrine and metabolic parameters is paramount to improve outcomes in this vulnerable population.

文摘BACKGROUND Pancreas transplantation(PT)has emerged as a critical therapeutic intervention for patients with type 1 diabetes mellitus(T1DM).This procedure restores neuroendocrine communication,which is essential for optimal pancreatic function and insulin regulation.The recovery process involves multiple phases,including neural regeneration,revascularization,and the re-establishment of synaptic connections,all of which contribute to the restoration of both endocrine and neurological functions.AIM To systematically examine the mechanisms underlying neurological recovery following PT,to explore the role of endocrine factors in restoring neurofunctional integrity,and to evaluate the impact of immunosuppressive therapy on nerve regeneration and its clinical outcomes.METHODS A comprehensive literature search was conducted across international databases such as PubMed,Web of Science,and Cochrane Library to identify studies addressing PT,neurological recovery,and endocrine regulation.Inclusion criteria encompassed randomized controlled trials,cohort studies,and systematic reviews.The review focused on the neurogenic mechanisms activated post-transplantation,the effect of glycemic control on nerve repair,and the implications of immunosuppressive drugs on the process of neurological recovery.RESULTS A total of 211 articles were initially identified through the literature search across international databases such as PubMed,Web of Science,and Cochrane Library.Following a detailed evaluation and the application of inclusion and exclusion criteria,56 articles were further reviewed,and 8 were selected for the final analysis.Additionally,a comprehensive patent search yielded 168 patents,out of which 6 were selected for further examination.These sources,including both journal literature and patents,offer significant insights into the mechanisms of neurological recovery and endocrine function following PT,with an emphasis on nerve regeneration,glycemic control,and the impact of immunosuppressive therapy.CONCLUSION PT represents a promising intervention for restoring both endocrine and neurological functions in patients with T1DM.Glycemic control,neural regeneration,and the restoration of neuroendocrine signaling are key components of successful recovery.While the procedure yields substantial improvements in nerve function,challenges persist,particularly in patients with long-standing diabetes or severe neuropathy.The dual impact of immunosuppressive drugs on immune suppression and neurotoxicity necessitates careful management.Future research should focus on refining immunosuppressive protocols and exploring advanced therapeutic options,including stem cell-based interventions,to enhance neural regeneration and further improve clinical outcomes.
文摘Endocrine disorders are increasingly recognized as potentially reversible causes of secondary cardiomyopathies,yet they often remain underdiagnosed in clinical practice.These conditions-including thyroid dysfunction,acromegaly,pheochromocytoma,diabetes mellitus,adrenal disorders,among others-can significantly alter cardiac structure and function through hormonal excess,metabolic remodeling,and neurohumoral activation.Hyperthyroidism may lead to high-output heart failure(HF)and atrial fibrillation,while hypothyroidism is associated with diastolic dysfunction,pericardial effusion,and accelerated atherosclerosis.Acromegaly promotes biventricular hypertrophy and myocardial fibrosis via insulin-like growth factor 1 overproduction.Pheochromocytoma triggers catecholamine-induced cardiomyopathy,resembling Takotsubo syndrome and carrying a high risk of mortality if left untreated.Diabetes induces a distinct phenotype of cardiomyopathy,affecting both systolic and diastolic function through microvascular injury and oxidative stress.Recognizing these endocrine etiologies is crucial,as targeted hormonal therapies-such as antithyroid agents,somatostatin analogs,or adrenalectomy-can reverse or significantly mitigate cardiac dysfunction.Comprehensive endocrine screening in patients with unexplained cardiomyopathy is therefore essential.This review synthesizes current knowledge on the pathophysiological mechanisms,clinical manifestations,and therapeutic strategies for endocrine cardiomyopathies and proposes a diagnostic algorithm for early recognition.Emerging biomarkers,such as galectin-3 in diabetic heart disease,may further enhance diagnostic accuracy and risk stratification.The interplay between endocrine and cardiovascular systems offers a unique opportunity for early intervention,potentially preventing progression to irreversible HF.

文摘Objective:Recurrence continues to be a pivotal challenge among hormone receptor-positive(HR^(+))/human epidermal growth factor receptor 2^(−)negative(HER2^(−))breast cancers.In the international consensus guidelines,HR^(+)/HER2^(−)breast cancer relapse patterns are divided into three distinct types:primary resistant,secondary resistant,and endocrine sensitive.However,owing to the lack of cohorts with treatment and follow-up data,the heterogeneity among different recurrence patterns remains uncharted.Current treatments still lack precision.Methods:This analysis included data from a large-scale multiomics study of a HR^(+)/HER2^(−)breast cancer cohort(n=314).Through the analysis of transcriptomics(n=312),proteomics(n=124),whole-exome sequencing(n=290),metabolomics(n=217),and digital pathology(n=228)data,we explored distinctive molecular features and identified putative therapeutic targets for patients experiencing recurrence.Results:We explored distinct clinicopathological characteristics,biological heterogeneity,and potential therapeutic strategies for recurrence.Based on a shared relapse signature,we stratified patients into high-and lowrecurrence-risk groups.Patients with different relapse patterns presented unique molecular features in primary tumors.Specifically,receptor tyrosine kinase(RTK)pathway activation in the primary resistant group suggested the utility of RTK inhibitors,whereas mammalian target of rapamycin(mTOR)and cell cycle pathway activation in the secondary resistant group highlighted the potential of mTOR and CDK4/6 inhibitors.Interestingly,the endocrine-sensitive group displayed a quiescent state and high genomic instability,suggesting that targeting quiescent cells and using poly-ADP-ribose polymerase(PARP)inhibitors could be effective strategies.Conclusions:These findings illuminate the clinicopathological and molecular landscape of HR^(+)/HER2^(−)breast cancer patients with distinct recurrence patterns,highlighting potential targeted therapies.

文摘The latest data from the NATALEE trial showed the absolute 3-year invasive disease-free survival benefit was 4.9%between the experimental and control groups.That is to say,in the intermediate-risk hormone receptor positive/human epidermal growth factor receptor-2 negative subgroup,there are also some patients with primary resistance to ribociclib.These patients benefit less from ribociclib,and they are unable to gain significant benefit even with the intensive adjuvant therapy of ribociclib.Considering the drug toxicity and health economic benefits,a 3-year course of ribociclib may not be appropriate for all intermediate-risk populations.Therefore,how to screen out the prime population for intensive adjuvant therapy of ribociclib needs to worth explored.In this paper,we discussed that the adaptive neoadjuvant endocrine therapy can screen out the prime population for intensive adjuvant therapy of ribociclib.

文摘Environmental endocrine disrupting chemicals （EDCs）, commonly found in the environment, come from industry and agriculture, including pesticides, fungicides, insecticides, herbicides, and other chemicals. Nowadays, more and more EDCs were released into the environment. EDCs go into water body via atmosphere sedi-mentation, surface runoff, soil eluviation, etc., so water body becomes the main place for existing. In order to attract scientific and public attention worldwide and to prevent EDCs pol ution, in this study we reviewed the classification of EDCs and their concentrations in natural water bodies, drinking water sources and water plants, and the reproductive toxicity of EDCs to fish were reviewed. EDCs could disturb the endocrine system and make reproductive organs and reproduction abnor-mal, resulting in fertility descending, reproduction function damage, community quan-tity decrease and even species extinction. In addition, EDCs could disrupt the homeostasis maintained by hormones, which would result in defects of neural de-velopment and abnormalities of the endocrine and reproductive systems. The exact molecular mechanisms have not been completely reported, but researches have suggested that multiple mechanisms were involved in the action of EDCs. Although there have been researches on the biohazard of EDCs, there stil exist problems of weakness in fundamental researches, difficulties in recognizing and identifying EDCs and high cost, which restraint the knowledge on them.

文摘[Objective] The study was to immunohistochemical localize the endocrine cells from digestive tract of Misgurnus [ Method ] Using six gastrointestinal hormone antisera, the endocrine cells from digestive tract of M. anguillicaudatus was localized. [ Result ]The 5-hydroxytryptamine immunoreactive（5-HT-IR） cells distribute in oesophagus, foregut and midgut; the distribution density was determined to be forepart of foregut 〉 oesophagus and hindpart of foregut 〉 gut, and the differences in the three density gradients reached significant level. Like PP-IR, SS-IR cells were observed mostly in oesophagus, followed by hindpart of foregut, least in forepart of foregut, but never found in gut and hindgut. The three kinds of immunocompetent cells Gas-IR, Glu-IR and SP-IR were not detected in each part of digestive tract. [ Conctusion] This study may provide basic data for studying the nutritional and digestive physiology, as well as the preparation of meridic diets for M. anguillicaudatus.

文摘Short-chain fatty acids,metabolites produced by the fermentation of dietary fiber by gut microbiota,have garnered significant attention due to their correlation with neurodegenerative diseases,particularly Parkinson’s disease.In this review,we summarize the changes in short-chain fatty acid levels and the abundance of short-chain fatty acid-producing bacteria in various samples from patients with Parkinson’s disease,highlighting the critical role of gut homeostasis imbalance in the pathogenesis and progression of the disease.Focusing on the nervous system,we discuss the molecular mechanisms by which short-chain fatty acids influence the homeostasis of both the enteric nervous system and the central nervous system.We identify key processes,including the activation of G protein-coupled receptors and the inhibition of histone deacetylases by short-chain fatty acids.Importantly,structural or functional disruptions in the enteric nervous system mediated by these fatty acids may lead to abnormalα-synuclein expression and gastrointestinal dysmotility,which could serve as an initiating event in Parkinson’s disease.Furthermore,we propose that short-chain fatty acids help establish communication between the enteric nervous system and the central nervous system via the vagal nerve,immune circulation,and endocrine signaling.This communication may shed light on their potential role in the transmission ofα-synuclein from the gut to the brain.Finally,we elucidate novel treatment strategies for Parkinson’s disease that target short-chain fatty acids and examine the challenges associated with translating short-chain fatty acid-based therapies into clinical practice.In conclusion,this review emphasizes the pivotal role of short-chain fatty acids in regulating gut-brain axis integrity and their significance in the pathogenesis of Parkinson’s disease from the perspective of the nervous system.Moreover,it highlights the potential value of short-chain fatty acids in early intervention for Parkinson’s disease.Future research into the molecular mechanisms of short-chain fatty acids and their synergistic interactions with other gut metabolites is likely to advance the clinical translation of innovative short-chain fatty acid-based therapies for Parkinson’s disease.
