Methods： On the basis of epidemiological investigation, 60 subjects with YDC and 50 with gentle constitution （GC） were selected according to the pertinent criteria. From each subject, 8 mL of fasting venous blood was drawn at 8：00-9：00 in the morning, with the serum separated by centrifugation 3 000 r/min for 5 min and preserved at -70℃ in a freezer. Serum levels of corticosterone, cortisol, adrenocorticotrophic hormone （ACTH）, cyclic adenosine monophosphate （cAMP）, cyclic guanosine monophosphate （cGMP）, free triiodothyronine （FT3）, free thyroxine （1=-1-4）, throtropic stimulation hormone, interleukin 1β （IL-1β ） and interleukin 2 （IL-2） were detected by doubleantibody sandwich ELISA; cAMP/cGMP ratio was calculated, and the difference between the two constitutions in terms of these indexes was analyzed. Results： Serum FT3 was 4.16 ± 1.38 pmol/L in subjects with YDC, which was higher than that in subjects with GC （3.71 ±0.55 pmol/L）, but levels of cortisol （124.58± 45.36 ng/mL）, ACTH （58.92± 14.55 pg/mL）, cGMP （66.00 ± 18.02 pmol/mL） and FT4 （12.33 ± 3.12 pmol/L） in YDC were lower than those in GC （13.43±2.31 pmol/L）, showing significant difference （P〈0.05）. Conclusion： YDC is related to some extent with the disturbances in the hypothalamus-pituitary-adrenal axis, hypothalamus-pituitary-thyroid axis, cyclic nucleoside system and immune function.展开更多

years,traditional Chinese medicine compounds and probiotics have shown good potential in regulating the endocrine system and improving the intestinal microecology,providing new ideas for the treatment of breast hyperplasia.OBJECTIVE:To explore the effects and mechanisms of traditional Chinese medicine compounds and fermented probiotic compounds on breast hyperplasia in mice,providing new theoretical and experimental bases for the clinical treatment and prevention of breast hyperplasia.METHODS:(1)Network pharmacology tools were used to predict the anti-breast-hyperplasia activity of Herba Gueldenstaedtiae(Euphorbia humifusa),as well as its potential targets and signaling pathways.The databases included:TCMSP,OMIM,GeneCards database,UniProt website,Venny2.1.0 website,Metascape,HERB website,and STRING database,all of which are open-access databases.Network pharmacology can predict and screen key information such as the targets corresponding to the active ingredients of traditional Chinese medicine,disease targets,and action pathways through network analysis and computer-system analysis.Therefore,it has been increasingly widely used in the research of traditional Chinese medicine.(2)A breast hyperplasia model was induced in mice by injecting estrogen and progesterone.Mice in the normal blank group were injected intraperitoneally with normal saline every day.Mice in the model group and drugadministration groups were injected intraperitoneally with estradiol benzoate injection at a concentration of 0.5 mg/kg every day for 25 days.From the 26th day,the injection of estradiol benzoate injection was stopped.Mice in the normal blank group were injected intramuscularly with normal saline every day,and mice in the model group and drug-administration groups were injected intramuscularly with progesterone injection at a concentration of 5 mg/kg for 5 days.After the model was established,each group was given drugs respectively.The normal blank group and the model group were gavaged with 0.2 mL/d of normal saline;the positive blank group(Xiaozheng Pill group)was gavaged with an aqueous solution of Xiaozheng Pill at 0.9 mg/g;the low-,medium-and high-dose groups of Compound Herba Gueldenstaedtiae were gavaged with an aqueous solution of the compound medicine at 0.75,1.5,and 3.0 mg/(g·d)respectively;the low-,medium-and high-dose groups of traditional Chinese medicine-bacteria fermentation were gavaged with an aqueous solution of the compound medicine at 0.75,1.5,and 3.0 mg/(g·d)respectively.The administration was continuous for 30 days.RESULTS AND CONCLUSION:(1)The results of network pharmacology research showed that the Compound Herba Gueldenstaedtiae(Euphorbia humifusa)contained 46 active ingredients,which were related to 1213 potential targets.After comparison with 588 known breast-hyperplasia targets,it was speculated that 50 of these targets might be related to the direct effect of the compound on breast hyperplasia.(2)After drug intervention,there was no significant change in the high-dose group of Compound Herba Gueldenstaedtiae compared with the normal blank group.The liver indicators of the other intervention groups all significantly decreased(P<0.05).(3)In terms of kidney and uterine indicators,the medium-dose group of Compound Herba Gueldenstaedtiae decreased significantly compared with the normal blank group(P<0.05).In terms of the uterine index,the model group increased significantly compared with the normal blank group(P<0.01).(4)After 1-month drug treatment,the number of lobules and acini in the breast tissue of the Xiaozheng Pill group,the low,medium,and high-dose group of Compound Herba Gueldenstaedtiae,the low,medium,and highdose groups of traditional Chinese medicine-bacteria fermentation decreased,and the duct openings narrowed.With the increase of drug dose,diffuse hyperplasia of breast tissue was significantly improved.(5)The ELISA results showed that compared with the model group,the estrogen level was lower in the medium-dose group of traditional Chinese medicine-bacteria fermentation after the intervention(P<0.05).In addition,the follicle-stimulating hormone level in the low-dose group of Compound Herba Gueldenstaedtiae was lower than that of the model group(P<0.05).(6)The intervention in the mouse model led to changes in the abundance of short chain fatty acids and intestinal flora in all groups.To conclude,the Compound Herba Gueldenstaedtiae and its probiotic fermentation products significantly improved mammary gland hyperplasia in mice by regulating hormone levels,improving the structure of the gut microbiota,and increasing the content of shortchain fatty acids,providing new ideas and potential sources of drugs for the treatment of breast hyperplasia.展开更多

文摘Objective： To explore the relationship between yin-deficiency constitution （YDC） and biochemical indexes by way of observing the endocrinal and immune functions in subjects with YDC. Methods： On the basis of epidemiological investigation, 60 subjects with YDC and 50 with gentle constitution （GC） were selected according to the pertinent criteria. From each subject, 8 mL of fasting venous blood was drawn at 8：00-9：00 in the morning, with the serum separated by centrifugation 3 000 r/min for 5 min and preserved at -70℃ in a freezer. Serum levels of corticosterone, cortisol, adrenocorticotrophic hormone （ACTH）, cyclic adenosine monophosphate （cAMP）, cyclic guanosine monophosphate （cGMP）, free triiodothyronine （FT3）, free thyroxine （1=-1-4）, throtropic stimulation hormone, interleukin 1β （IL-1β ） and interleukin 2 （IL-2） were detected by doubleantibody sandwich ELISA; cAMP/cGMP ratio was calculated, and the difference between the two constitutions in terms of these indexes was analyzed. Results： Serum FT3 was 4.16 ± 1.38 pmol/L in subjects with YDC, which was higher than that in subjects with GC （3.71 ±0.55 pmol/L）, but levels of cortisol （124.58± 45.36 ng/mL）, ACTH （58.92± 14.55 pg/mL）, cGMP （66.00 ± 18.02 pmol/mL） and FT4 （12.33 ± 3.12 pmol/L） in YDC were lower than those in GC （13.43±2.31 pmol/L）, showing significant difference （P〈0.05）. Conclusion： YDC is related to some extent with the disturbances in the hypothalamus-pituitary-adrenal axis, hypothalamus-pituitary-thyroid axis, cyclic nucleoside system and immune function.

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.
文摘Pediatric pancreatic tumors,though rare,pose significant diagnostic and manage-ment challenges.The recent,22-year nationwide survey on pediatric pancreatic tumors in Japan by Makita et al offers valuable insights into this uncommon enti-ty,revealing striking geographical variations and questioning current treatment paradigms.This editorial commentary analyzes the study's key findings,inclu-ding the predominance of solid pseudopapillary neoplasms and their younger age of onset,which contrast sharply with Western data.It explores the implications for clinical practice and research,emphasizing the need for population-specific approaches to diagnosis and treatment.The revealed limited institutional expe-rience and surgical management patterns prompt a reevaluation of optimal care delivery for these complex cases,suggesting benefits of centralizing healthcare services.Furthermore,the commentary advocates for international collaborative studies to elucidate the genetic,environmental,and lifestyle factors influencing the development and progression of pediatric pancreatic tumors across diverse populations.It also outlines future directions,calling for advancements in precision medicine and innovative care delivery models to improve global patient outcomes.Unraveling Makita et al's findings within the broader landscape of pediatric oncology can stimulate further research and clinical advancements in managing pancreatic and other rare tumors in children.
文摘BACKGROUND:Breast hyperplasia is a common benign breast disease mainly caused by endocrine disorders,manifested as abnormal hyperplasia of breast tissue.In recent years,traditional Chinese medicine compounds and probiotics have shown good potential in regulating the endocrine system and improving the intestinal microecology,providing new ideas for the treatment of breast hyperplasia.OBJECTIVE:To explore the effects and mechanisms of traditional Chinese medicine compounds and fermented probiotic compounds on breast hyperplasia in mice,providing new theoretical and experimental bases for the clinical treatment and prevention of breast hyperplasia.METHODS:(1)Network pharmacology tools were used to predict the anti-breast-hyperplasia activity of Herba Gueldenstaedtiae(Euphorbia humifusa),as well as its potential targets and signaling pathways.The databases included:TCMSP,OMIM,GeneCards database,UniProt website,Venny2.1.0 website,Metascape,HERB website,and STRING database,all of which are open-access databases.Network pharmacology can predict and screen key information such as the targets corresponding to the active ingredients of traditional Chinese medicine,disease targets,and action pathways through network analysis and computer-system analysis.Therefore,it has been increasingly widely used in the research of traditional Chinese medicine.(2)A breast hyperplasia model was induced in mice by injecting estrogen and progesterone.Mice in the normal blank group were injected intraperitoneally with normal saline every day.Mice in the model group and drugadministration groups were injected intraperitoneally with estradiol benzoate injection at a concentration of 0.5 mg/kg every day for 25 days.From the 26th day,the injection of estradiol benzoate injection was stopped.Mice in the normal blank group were injected intramuscularly with normal saline every day,and mice in the model group and drug-administration groups were injected intramuscularly with progesterone injection at a concentration of 5 mg/kg for 5 days.After the model was established,each group was given drugs respectively.The normal blank group and the model group were gavaged with 0.2 mL/d of normal saline;the positive blank group(Xiaozheng Pill group)was gavaged with an aqueous solution of Xiaozheng Pill at 0.9 mg/g;the low-,medium-and high-dose groups of Compound Herba Gueldenstaedtiae were gavaged with an aqueous solution of the compound medicine at 0.75,1.5,and 3.0 mg/(g·d)respectively;the low-,medium-and high-dose groups of traditional Chinese medicine-bacteria fermentation were gavaged with an aqueous solution of the compound medicine at 0.75,1.5,and 3.0 mg/(g·d)respectively.The administration was continuous for 30 days.RESULTS AND CONCLUSION:(1)The results of network pharmacology research showed that the Compound Herba Gueldenstaedtiae(Euphorbia humifusa)contained 46 active ingredients,which were related to 1213 potential targets.After comparison with 588 known breast-hyperplasia targets,it was speculated that 50 of these targets might be related to the direct effect of the compound on breast hyperplasia.(2)After drug intervention,there was no significant change in the high-dose group of Compound Herba Gueldenstaedtiae compared with the normal blank group.The liver indicators of the other intervention groups all significantly decreased(P<0.05).(3)In terms of kidney and uterine indicators,the medium-dose group of Compound Herba Gueldenstaedtiae decreased significantly compared with the normal blank group(P<0.05).In terms of the uterine index,the model group increased significantly compared with the normal blank group(P<0.01).(4)After 1-month drug treatment,the number of lobules and acini in the breast tissue of the Xiaozheng Pill group,the low,medium,and high-dose group of Compound Herba Gueldenstaedtiae,the low,medium,and highdose groups of traditional Chinese medicine-bacteria fermentation decreased,and the duct openings narrowed.With the increase of drug dose,diffuse hyperplasia of breast tissue was significantly improved.(5)The ELISA results showed that compared with the model group,the estrogen level was lower in the medium-dose group of traditional Chinese medicine-bacteria fermentation after the intervention(P<0.05).In addition,the follicle-stimulating hormone level in the low-dose group of Compound Herba Gueldenstaedtiae was lower than that of the model group(P<0.05).(6)The intervention in the mouse model led to changes in the abundance of short chain fatty acids and intestinal flora in all groups.To conclude,the Compound Herba Gueldenstaedtiae and its probiotic fermentation products significantly improved mammary gland hyperplasia in mice by regulating hormone levels,improving the structure of the gut microbiota,and increasing the content of shortchain fatty acids,providing new ideas and potential sources of drugs for the treatment of breast hyperplasia.
文摘In this article,we have commented on the article by Augustin et al.The authors presented a systematic review of the diagnosis,treatment,and outcomes of primary hyperparathyroidism-induced acute pancreatitis in pregnant women.Since acute pancreatitis during pregnancy could cause maternal as well as fetal adverse outcomes,understanding this pathology is essential.Although there are various etiologies of acute pancreatitis during pregnancy,primary hyperparathyroidism is one of the causes that complicate hypercalcemia.Along with conventional treatment for acute pancreatitis,parathyroidectomy can effectively normalize calcium levels and improve acute pancreatitis.Augustin et al have provided vital information that can enable physicians to understand and treat hyperparathyroidism-induced acute pancreatitis in pregnant women,which could contribute to better maternal and fetal outcomes.In addition,since primary hyperparathyroidism is associated with multiple endocrine neoplasia,further consideration regarding screening for multiple endocrine neoplasia might lead to better prognoses.

文摘Objective:To evaluate the antioxidant activity of Kaempferia(K.)parviflora rhizome extract and study its protective effect against male reproductive impairment induced by fenitrothion.Methods:The phytochemicals and antioxidant properties of K.parviflora ethanolic extract were assessed.Twenty-four male mice aged 4-weeks-old were assigned into four groups.Groups 1 to 4 respectively received extra virgin olive oil(served as the vehicle control),20 mg/kg body weight(bw)of fenitrothion,50 mg/kg bw of K.parviflora ethanolic extract,and 50 mg/kg bw of K.parviflora ethanolic extract plus 20 mg/kg bw of fenitrothion.Upon completion of 28 days of continuous feeding treatment,the mice were subjected to mating evaluation and the assessment of epididymal sperm quality,lipid peroxidation,testosterone level and histological evaluation.Results:Eight phytochemical compounds were detected in the ethanolic extract of K.parviflora via GC-MS.The extract exhibited a DPPH radical scavenging activity with an EC50 value of(0.870±0.007)mg/mL.Mice fed with fenitrothion in group 2 displayed an increase in relative testis weight,lipid peroxidation levels and a significant reduction in all sperm parameters(sperm concentration,progressive motility,and viability),as well as serum testosterone levels compared to the control mice in group 1(P<0.05).On the other hand,mice fed with K.parviflora ethanolic extract in group 3 showed a significant increase in serum testosterone levels compared to group 1.Mice co-administered with K.parviflora ethanolic extract and fenitrothion in group 4 exhibited a significant improvement in testosterone levels,sperm concentration,motility,and viability compared to the mice administered only with fenitrothion in group 2(P<0.05).Histological analysis of testicular tissue from group 4 further revealed improved testicular morphology in comparison to fenitrothion-treated mice.Conclusions:Eight bioactive compounds were identified in K.parviflora ethanolic extract and the extract exhibited antioxidative properties.Fenitrothion administration impairs testicular function,reducing sperm parameters and testosterone while increasing lipid peroxidation.However,K.parviflora ethanolic extract coadministration alleviates oxidative stress,improves sperm parameters and testosterone levels,and enhances testicular morphology.These findings suggest that K.parviflora ethanolic extract has the therapeutic potential in mitigating male reproductive adverse effects induced by fenitrothion.
文摘Multiple endocrine neoplasia type 1(MEN1)is an autosomal-inherited syndrome involving multiple endocrine tumors.It is characterized by multiple mutations in the tumor suppressor gene MEN1,which is located on chromosome 11q13.As main etiology of MEN1 is genetic mutations,clinical symptoms may vary.In this editorial,we comment on the article by Yuan et al.This article describes a case of(MEN1)characterized by low incidence and diagnostic complexity.MEN1 co-mmonly presents as parathyroid,pancreatic,and pituitary tumors.Diagnosis requires a combination of serologic tests,magnetic resonance imaging,computed tomography,endoscopic ultrasonography,immunologic and pathology.The diagnosis is unique depending on the site of disease.Surgical resection is the treatment of choice for MEN1.The prognosis depends on the site of origin,but early detection and intervention is the most effective.

文摘An increasing number of studies have characterized the bone as an endocrine organ,and that bone secreted factors may not only regulate local bone remodeling,but also other tissues and whole-body metabolic functions.The precise nature of these regulatory factors and their roles at bridging the bone,bone marrow adipose tissue,extramedullary body fat and whole-body energy homeostasis are being explored.In this study,we report that KIAA1199,a secreted factor produced from bone and bone marrow,previously described as an inhibitor of bone formation,also plays a role at promoting adipogenesis.KIAA1199-deficient mice exhibit reduced bone marrow adipose tissue,subcutaneous and visceral fat tissue mass,blood cholesterol,triglycerides,free fatty acids and glycerol,as well as improved insulin sensitivity in skeletal muscle,liver and fat.Moreover,these mice are protected from the detrimental effects of high-fat diet feeding,with decreased obesity,lower blood glucose and glucose tolerance,as well as decreased adipose tissue inflammation,insulin resistance and hepatic steatosis.In human studies,plasma levels of KIAA1199 or its expression levels in adipose tissue are positively correlated with insulin resistance and blood levels of cholesterol,triglycerides,free fatty acids,glycerol,fasting glucose and HOMA-IR.Mechanistically,KIAA1199 mediates its effects on adipogenesis through modulating osteopontin-integrin and AKT/ERK signaling.These findings provide evidence for the role of bone secreted factors on coupling bone,fat and whole-body energy homeostasis.
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Frozen shoulder(FS),also known as adhesive capsulitis,is a condition that causes contraction and stiffness of the shoulder joint capsule.The main symptoms are per-sistent shoulder pain and a limited range of motion in all directions.These symp-toms and poor prognosis affect people's physical health and quality of life.Currently,the specific mechanisms of FS remain unclear,and there is variability in treatment methods and their efficacy.Additionally,the early symptoms of FS are difficult to distinguish from those of other shoulder diseases,complicating early diagnosis and treatment.Therefore,it is necessary to develop and utilize animal models to under-stand the pathogenesis of FS and to explore treatment strategies,providing insights into the prevention and treatment of human FS.This paper reviews the rat models available for FS research,including external immobilization models,surgical internal immobilization models,injection modeling models,and endocrine modeling models.It introduces the basic procedures for these models and compares and analyzes the advantages,disadvantages,and applicability of each modeling method.Finally,our paper summarizes the common methods for evaluating FS rat models.
文摘The increasing longevity of patients with transfusion-dependent homozygous beta-thalassemia has brought endocrine complications to the forefront of longterm care.While iron overload remains a central mechanism,additional contributors such as hypothalamic dysfunction,neurosecretory disturbances,and chronic inflammation have been identified.Endocrine disorders including hypothyroidism,adrenal insufficiency,hypogonadotropic hypogonadism,hypoparathyroidism,osteoporosis,and growth axis impairment-are prevalent and often underdiagnosed.Diagnostic challenges include normal hormone levels in early stages,necessitating the use of dynamic endocrine testing and pituitary magnetic resonance imaging to detect subclinical dysfunction.Risk is modulated by sex,age,and chelation adherence.Early identification and proactive,multidisciplinary management of endocrine sequelae are essential in reducing morbidity and maintaining functional independence in this aging patient population.
文摘Thyroid nodules,a common disorder in the endocrine system,require accurate segmentation in ultrasound images for effective diagnosis and treatment.However,achieving precise segmentation remains a challenge due to various factors,including scattering noise,low contrast,and limited resolution in ultrasound images.Although existing segmentation models have made progress,they still suffer from several limitations,such as high error rates,low generalizability,overfitting,limited feature learning capability,etc.To address these challenges,this paper proposes a Multi-level Relation Transformer-based U-Net(MLRT-UNet)to improve thyroid nodule segmentation.The MLRTUNet leverages a novel Relation Transformer,which processes images at multiple scales,overcoming the limitations of traditional encoding methods.This transformer integrates both local and global features effectively through selfattention and cross-attention units,capturing intricate relationships within the data.The approach also introduces a Co-operative Transformer Fusion(CTF)module to combine multi-scale features from different encoding layers,enhancing the model’s ability to capture complex patterns in the data.Furthermore,the Relation Transformer block enhances long-distance dependencies during the decoding process,improving segmentation accuracy.Experimental results showthat the MLRT-UNet achieves high segmentation accuracy,reaching 98.2% on the Digital Database Thyroid Image(DDT)dataset,97.8% on the Thyroid Nodule 3493(TG3K)dataset,and 98.2% on the Thyroid Nodule3K(TN3K)dataset.These findings demonstrate that the proposed method significantly enhances the accuracy of thyroid nodule segmentation,addressing the limitations of existing models.

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The endocrine-disrupting chemicals(EDCs)and antibiotics are causing negative effects on human beings and animals by disrupting the endocrine system and spreading antimicrobial resistance.The current need is to eradicate pharmaceutical waste from water bodies using advanced catalytic systems with high efficiency.Novel ternary carbon quantum dots(CQDs)decorated Z-Scheme WS_(2)-PANI nanocomposite was prepared by a green synthesis assisted in-situ polymerization for the photodegradation and detection of Estradiol(EST)and Nitrofurantoin(NFT).HRTEM micrographs revealed the formation of CQDs with a mean size of 4nm anchored on the surface of WS_(2)/PANI(width:PANI~20-30nm).The ternary nanocomposite showed excellent photocatalytic activity,degraded NFT(95.7%in 60min),and EST(96.6%in 60min).The rate kinetics study confirms the reaction followed pseudo first-order model.This heterostructure exhibited enhanced performances by modulating the energy level configuration,enhancing the absorption of visible light(2.4eV),and significantly improving the charge separation,three times higher than pristine WS_(2).These are highly favorable for increasing the generation of photoinduced charges and enhancing the overall performance of the catalyst.Further,the electrochemical sensor was prepared using CQDs@WS_(2)/PANI nanocomposite on a paper-based electrode.The CQDs@WS_(2)/PANI exhibit a linear response of 0.1-100nM,with a limit of detection of 13nM.This synergistic interfacial interaction resulted in the significantly improved electrochemical performance of the modified electrode.The proposed Z-scheme was justified by electron paramagnetic resonance(EPR)and scavenger experiment.An intermediate degradation pathway was also proposed.The synthesized materials were characterized using FESEM,HRTEM,XRD,FTIR,XPS,UV-visible spectroscopy,PL,and TRPL.Therefore,this study provides a direct approach to fabricate a heterojunction that combines two-dimensional,one dimensional,and zero-dimensional properties,enabling control over the energy level configuration and subsequent improvements in photocatalytic and electrocatalytic efficiency.

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One of the main causes of liver fibrosis and cancer,non-alcoholic fatty liver disease(NAFLD)is becoming more common every year.The novel work by Yu et al,which evaluates the viability and efficacy of duodenal mucosal ablation(DMA)with irreversible electroporation(IRE)in NAFLD rat models,is examined in this article.When DMA was used with IRE to small rodents,the study found that the duodenum healed successfully two weeks later and had thicker myenterons,narrower and shallower crypts,and slimmer villi than in the sham-control group.When DMA with IRE were used,liver lipid deposition and serum lipid index values decreased;these improvements occurred regardless of food consumption or weight loss.Furthermore,the DMA group's enteroendocrine parameters varied among the various duodenal areas,including claudin and zonula ocludens-1 Levels in the duodenal mucosa.As a result,DMA with IRE in rodents demonstrated no duodenal bleeding or perforation following ablation,providing a promising path for more advanced NAFLD treatment approaches.In order to improve approach outcomes,this paper addresses the implications of extending the study length and animal size,analyzing inflammatory marker studies,and measuring intestinal lipid indexes and endocrine parameters on a weekly basis.
