The neuron is one of the most basic and important structural and functional units of the central nervous system, with sensory stimulation and excitation conduction functions. Astrocytes and microglia belong to the glial cell family, which is the main source of cytokines and represents the main defense system of the central nervous system. Nerve cells undergo neurotransmission or gliotransmission, which regulates neuronal activity via the ion channels, receptors, or transporters expressed on nerve cell membranes. Ion channels, composed of large transmembrane proteins, play crucial roles in maintaining nerve cell homeostasis. These channels are also important for control of the membrane potential and in the secretion of neurotransmitters. A variety of cellular functions and life activities, including functional regulation of the central nervous system, the generation and conduction of nerve excitation, the occurrence of receptor potential, heart pulsation, smooth muscle peristalsis, skeletal muscle contraction, and hormone secretion, are closely related to ion channels associated with passive transmembrane transport. Two types of ion channels in the central nervous system, potassium channels and calcium channels, are closely related to various neurological disorders, including Alzheimer's disease, Parkinson's disease, and epilepsy. Accordingly, various drugs that can affect these ion channels have been explored deeply to provide new directions for the treatment of these neurological disorders. In this review, we focus on the functions of potassium and calcium ion channels in different nerve cells and their involvement in neurological disorders such as Parkinson's disease, Alzheimer's disease, depression, epilepsy, autism, and rare disorders. We also describe several clinical drugs that target potassium or calcium channels in nerve cells and could be used to treat these disorders. We concluded that there are few clinical drugs that can improve the pathology these diseases by acting on potassium or calcium ions. Although a few novel ion-channelspecific modulators have been discovered, meaningful therapies have largely not yet been realized. The lack of target-specific drugs, their requirement to cross the blood–brain barrier, and their exact underlying mechanisms all need further attention. This review aims to explain the urgent problems that need research progress and provide comprehensive information aiming to arouse the research community's interest in the development of ion channel-targeting drugs and the identification of new therapeutic targets for that can increase the cure rate of nervous system diseases and reduce the occurrence of adverse reactions in other systems.展开更多

This study sought to investigate the coping strategies adopted by construction employees to deal with the causes and effects of occupational psychological disorders such as burnout and workaholism. To achieve this aim, the methods of focus group discussions were first employed. A total of 16 semi-structured focus group discussions were held in Ghana, with 90 construction employees. The focus group study revealed 25 coping strategies adopted as efforts to mitigate the causes and 22 coping strategies adopted as responses to moderate the effects of occupational psychological disorders. A quantitative study involving 150 construction professionals and 150 construction trade workers were also conducted in Ghana to investigate the coping strategies that were highly adopted by the two construction working groups. The findings from the study revealed that the construction professionals adopted delegating complicated tasks and seeking medical attention as the most common coping strategies to manage the causes and effects respectively. The construction trade workers were also revealed to adopt withdrawing from work duties or changing jobs and taking in more caffeinated drinks as the most common coping strategies to manage the causes and effects respectively. Exploratory factor analysis was employed, and the findings were put into the main constructs. The causes focused coping strategies were categorized under avoidance, alteration, adaptation, and acceptance. The effects focused coping strategies were also categorized under healthy and unhealthy coping strategies. This study recommends appropriate coping strategies and interventions in the construction industry such as education of construction personnel on the consequences of various coping strategies.展开更多

This study focused on six personal intervening factors that were associated with the risks of occupational psychological disorders namely: low self-esteem, negative personality trait, unproductive core beliefs, poor self-concept evaluation on performance, poor relationship with others and poor time management skills. An investigation on the level of severity of these personal intervening factors was conducted involving 150 construction professionals and 150 construction trade workers, who were purposively selected in Ghana. The personal factors that were found to be prevalent among the construction employees were low self-esteem and poor time management skills. Correlation analysis and regression analysis were used to determine the relationships between the personal intervening factors and demographic factors such as the age, educational levels and marital status of the research participants. The results of the study indicated that the age and marital status of the respondents had no significant relationship with any of the personal intervening factors. Personal factors such as personality trait and relationship with others also had no relation with any of the demographic factors analyzed. The educational level of the respondents, however, had a significant relationship with the factors of self-esteem, productive core beliefs, self-evaluation on performance and time management skills. An independent two-sample T-test was used to compare the means of the factors with significant relations. This study revealed that construction employees who were highly educated had better self-esteem and time management skills than those who were less educated. The findings from this study broaden the view of moderators on influential sources of psychological health conditions of employees.展开更多

Method: A cross-sectional study was conducted on 102 Chinese patients with common mental disorders and being followed up in two public integrated mental health clinics in Hong Kong from 1<sup>st</sup> November 2020 to 31<sup>st</sup> January 2021. Patients would be evaluated about the impact of COVID-19 pandemic on their mood and daily life by using a questionnaire which assessed social distancing effects, financial impact, relationship with family, anxiety and depressive symptoms. The Patient Health Questionnaire-9 (PHQ-9) and General Anxiety Disorder-7 Questionnaire (GAD-7) would also be used to assess patients’ mood symptoms. Factors which were related to COVID-19 pandemic and associated with anxiety or depressive symptoms would be analysed. Results: The mean age of the subjects was 58.0 years and more patients were female (77.5%). There were 84.3% and 72.5% of patients reported their anxiety and depressive symptoms being affected by COVID-19 pandemic respectively. It was found that 17.6% of patients had their income decreased or were unemployed. About one-third (30.4%) of patients indicated that their relationship with their family was worsened while 8.8% was improved. Social distancing was significantly associated with anxiety (p = 0.006) and depressive symptoms (p 0.001) in patients with common mental disorders. Conclusion: There was considerably more psychological impact including an increase in anxiety and depressive symptoms due to COVID-19 pandemic in Chinese patients with existing common mental disorders in primary care. Primary care physicians should raise their awareness of the psychological impact of COVID-19 pandemic on their patients. Our findings shed light on mental health care planning and preventive measures during the COVID-19 pandemic and potential subsequent pandemics.展开更多

文摘Tropomyosin receptor kinase B(TrkB)signaling plays a pivotal role in dendritic growth and dendritic spine formation to promote learning and memory.The activity-dependent release of brain-derived neurotrophic factor at synapses binds to pre-or postsynaptic TrkB resulting in the strengthening of synapses,reflected by long-term potentiation.Postsynaptically,the association of postsynaptic density protein-95 with TrkB enhances phospholipase Cγ-Ca^(2+)/calmodulin-dependent protein kinaseⅡand phosphatidylinositol 3-kinase-mechanistic target of rapamycin signaling required for long-term potentiation.In this review,we discuss TrkB-postsynaptic density protein-95 coupling as a promising strategy to magnify brain-derived neurotrophic factor signaling towards the development of novel therapeutics for specific neurological disorders.A reduction of TrkB signaling has been observed in neurodegenerative disorders,such as Alzheimer's disease and Huntington's disease,and enhancement of postsynaptic density protein-95 association with TrkB signaling could mitigate the observed deficiency of neuronal connectivity in schizophrenia and depression.Treatment with brain-derived neurotrophic factor is problematic,due to poor pharmacokinetics,low brain penetration,and side effects resulting from activation of the p75 neurotrophin receptor or the truncated TrkB.T1 isoform.Although TrkB agonists and antibodies that activate TrkB are being intensively investigated,they cannot distinguish the multiple human TrkB splicing isoforms or cell type-specific functions.Targeting TrkB–postsynaptic density protein-95 coupling provides an alternative approach to specifically boost TrkB signaling at localized synaptic sites versus global stimulation that risks many adverse side effects.

文摘Neuromyelitis optica spectrum disorders are neuroinflammatory demyelinating disorders that lead to permanent visual loss and motor dysfunction.To date,no effective treatment exists as the exact causative mechanism remains unknown.Therefore,experimental models of neuromyelitis optica spectrum disorders are essential for exploring its pathogenesis and in screening for therapeutic targets.Since most patients with neuromyelitis optica spectrum disorders are seropositive for IgG autoantibodies against aquaporin-4,which is highly expressed on the membrane of astrocyte endfeet,most current experimental models are based on aquaporin-4-IgG that initially targets astrocytes.These experimental models have successfully simulated many pathological features of neuromyelitis optica spectrum disorders,such as aquaporin-4 loss,astrocytopathy,granulocyte and macrophage infiltration,complement activation,demyelination,and neuronal loss;however,they do not fully capture the pathological process of human neuromyelitis optica spectrum disorders.In this review,we summarize the currently known pathogenic mechanisms and the development of associated experimental models in vitro,ex vivo,and in vivo for neuromyelitis optica spectrum disorders,suggest potential pathogenic mechanisms for further investigation,and provide guidance on experimental model choices.In addition,this review summarizes the latest information on pathologies and therapies for neuromyelitis optica spectrum disorders based on experimental models of aquaporin-4-IgG-seropositive neuromyelitis optica spectrum disorders,offering further therapeutic targets and a theoretical basis for clinical trials.

文摘The central nervous system, information integration center of the body, is mainly composed of neurons and glial cells. The neuron is one of the most basic and important structural and functional units of the central nervous system, with sensory stimulation and excitation conduction functions. Astrocytes and microglia belong to the glial cell family, which is the main source of cytokines and represents the main defense system of the central nervous system. Nerve cells undergo neurotransmission or gliotransmission, which regulates neuronal activity via the ion channels, receptors, or transporters expressed on nerve cell membranes. Ion channels, composed of large transmembrane proteins, play crucial roles in maintaining nerve cell homeostasis. These channels are also important for control of the membrane potential and in the secretion of neurotransmitters. A variety of cellular functions and life activities, including functional regulation of the central nervous system, the generation and conduction of nerve excitation, the occurrence of receptor potential, heart pulsation, smooth muscle peristalsis, skeletal muscle contraction, and hormone secretion, are closely related to ion channels associated with passive transmembrane transport. Two types of ion channels in the central nervous system, potassium channels and calcium channels, are closely related to various neurological disorders, including Alzheimer's disease, Parkinson's disease, and epilepsy. Accordingly, various drugs that can affect these ion channels have been explored deeply to provide new directions for the treatment of these neurological disorders. In this review, we focus on the functions of potassium and calcium ion channels in different nerve cells and their involvement in neurological disorders such as Parkinson's disease, Alzheimer's disease, depression, epilepsy, autism, and rare disorders. We also describe several clinical drugs that target potassium or calcium channels in nerve cells and could be used to treat these disorders. We concluded that there are few clinical drugs that can improve the pathology these diseases by acting on potassium or calcium ions. Although a few novel ion-channelspecific modulators have been discovered, meaningful therapies have largely not yet been realized. The lack of target-specific drugs, their requirement to cross the blood–brain barrier, and their exact underlying mechanisms all need further attention. This review aims to explain the urgent problems that need research progress and provide comprehensive information aiming to arouse the research community's interest in the development of ion channel-targeting drugs and the identification of new therapeutic targets for that can increase the cure rate of nervous system diseases and reduce the occurrence of adverse reactions in other systems.

文摘Rare neurological diseases,while individually are rare,collectively impact millions globally,leading to diverse and often severe neurological symptoms.Often attributed to genetic mutations that disrupt protein function or structure,understanding their genetic basis is crucial for accurate diagnosis and targeted therapies.To investigate the underlying pathogenesis of these conditions,researchers often use non-mammalian model organisms,such as Drosophila(fruit flies),which is valued for their genetic manipulability,cost-efficiency,and preservation of genes and biological functions across evolutionary time.Genetic tools available in Drosophila,including CRISPR-Cas9,offer a means to manipulate gene expression,allowing for a deep exploration of the genetic underpinnings of rare neurological diseases.Drosophila boasts a versatile genetic toolkit,rapid generation turnover,and ease of large-scale experimentation,making it an invaluable resource for identifying potential drug candidates.Researchers can expose flies carrying disease-associated mutations to various compounds,rapidly pinpointing promising therapeutic agents for further investigation in mammalian models and,ultimately,clinical trials.In this comprehensive review,we explore rare neurological diseases where fly research has significantly contributed to our understanding of their genetic basis,pathophysiology,and potential therapeutic implications.We discuss rare diseases associated with both neuron-expressed and glial-expressed genes.Specific cases include mutations in CDK19 resulting in epilepsy and developmental delay,mutations in TIAM1 leading to a neurodevelopmental disorder with seizures and language delay,and mutations in IRF2BPL causing seizures,a neurodevelopmental disorder with regression,loss of speech,and abnormal movements.And we explore mutations in EMC1 related to cerebellar atrophy,visual impairment,psychomotor retardation,and gain-of-function mutations in ACOX1 causing Mitchell syndrome.Loss-of-function mutations in ACOX1 result in ACOX1 deficiency,characterized by very-long-chain fatty acid accumulation and glial degeneration.Notably,this review highlights how modeling these diseases in Drosophila has provided valuable insights into their pathophysiology,offering a platform for the rapid identification of potential therapeutic interventions.Rare neurological diseases involve a wide range of expression systems,and sometimes common phenotypes can be found among different genes that cause abnormalities in neurons or glia.Furthermore,mutations within the same gene may result in varying functional outcomes,such as complete loss of function,partial loss of function,or gain-of-function mutations.The phenotypes observed in patients can differ significantly,underscoring the complexity of these conditions.In conclusion,Drosophila represents an indispensable and cost-effective tool for investigating rare neurological diseases.By facilitating the modeling of these conditions,Drosophila contributes to a deeper understanding of their genetic basis,pathophysiology,and potential therapies.This approach accelerates the discovery of promising drug candidates,ultimately benefiting patients affected by these complex and understudied diseases.
文摘BACKGROUND Disorders of gut-brain interaction(DGBI)are common,but knowledge about their physiopathology is still poor,nor valid tools have been used to evaluate them in childhood.AIM To develop a psycho-gastroenterological questionnaire(PGQ)to assess the psycho-gastroenterological profile and social characteristics of a pediatric population with and without DGBI.METHODS One hundred and nineteen Italian children(age 11-18)were included:28 outpatient patients with DGBI(Rome IV criteria)and 91 healthy controls.They filled the PGQ,faces pain scale revised(FPS-R),Bristol stool chart,ga-strointestinal symptoms rating scale,state-trait anxiety inventory,Toronto alexithymia scale 20,perceived self-efficacy in the management of negative emotions and expression of positive emotions(APEN-G,APEP-G),irritable bowel syndrome-quality of life questionnaire,school performances,tobacco use,early life events,degree of digital-ization.RESULTS Compared to controls,patients had more medical examinations(35%of them went to the doctor more than five times),a higher school performance(23%vs 13%,P<0.05),didn’t use tobacco(never vs 16%,P<0.05),had early life events(28%vs 1%P<0.05)and a higher percentage of pain classified as 4 in the FPS-R during the examination(14%vs 7%,P<0.05).CONCLUSION Pediatric outpatients with DGBI had a higher prevalence of early life events,a lower quality of life,more medical examinations rising health care costs,lower anxiety levels.

文摘Various nanoparticle-based drug delivery systems for the treatment of neurological disorders have been widely studied.However,their inability to cross the blood–brain barrier hampers the clinical translation of these therapeutic strategies.Liposomes are nanoparticles composed of lipid bilayers,which can effectively encapsulate drugs and improve drug delivery across the blood–brain barrier and into brain tissue through their targeting and permeability.Therefore,they can potentially treat traumatic and nontraumatic central nervous system diseases.In this review,we outlined the common properties and preparation methods of liposomes,including thin-film hydration,reverse-phase evaporation,solvent injection techniques,detergent removal methods,and microfluidics techniques.Afterwards,we comprehensively discussed the current applications of liposomes in central nervous system diseases,such as Alzheimer's disease,Parkinson's disease,Huntington's disease,amyotrophic lateral sclerosis,traumatic brain injury,spinal cord injury,and brain tumors.Most studies related to liposomes are still in the laboratory stage and have not yet entered clinical trials.Additionally,their application as drug delivery systems in clinical practice faces challenges such as drug stability,targeting efficiency,and safety.Therefore,we proposed development strategies related to liposomes to further promote their development in neurological disease research.
文摘pupils aged 9~12 years from six primary schools were cross-sectionally investigated on the psychological disorders with Conner Scale and EPQ. The results showed that the incidence of psychological disorders was 18. 2%,with 21. 3% in male and 15. 5% in female. The incidehees were significantly difrerent between male and remal (P<0. 05). The incidences or learning difficulty,hyperactivity and impulsive behavior were 8. 2%, 5. 3%,and 5.3% respectively.The family factors influencing the psychological disorders were the pupils'birth problems,the relationship between the pupils and their parents, and the parents'inappropriate prospect for the pupils.The investigation also found that the pupils with psychological disorders had more poor experiences or their family and school and more of them had obvious personality tendencies towards unstability or emotion,eccentricity and social immaturity as compared with the normal pupils. The effective measures to promote pupils'psychological health were suggested in this article.
文摘Coping strategies adopted to deal with psychological health issues could have influences on the general health, productivity and task performance of the employee. This study sought to investigate the coping strategies adopted by construction employees to deal with the causes and effects of occupational psychological disorders such as burnout and workaholism. To achieve this aim, the methods of focus group discussions were first employed. A total of 16 semi-structured focus group discussions were held in Ghana, with 90 construction employees. The focus group study revealed 25 coping strategies adopted as efforts to mitigate the causes and 22 coping strategies adopted as responses to moderate the effects of occupational psychological disorders. A quantitative study involving 150 construction professionals and 150 construction trade workers were also conducted in Ghana to investigate the coping strategies that were highly adopted by the two construction working groups. The findings from the study revealed that the construction professionals adopted delegating complicated tasks and seeking medical attention as the most common coping strategies to manage the causes and effects respectively. The construction trade workers were also revealed to adopt withdrawing from work duties or changing jobs and taking in more caffeinated drinks as the most common coping strategies to manage the causes and effects respectively. Exploratory factor analysis was employed, and the findings were put into the main constructs. The causes focused coping strategies were categorized under avoidance, alteration, adaptation, and acceptance. The effects focused coping strategies were also categorized under healthy and unhealthy coping strategies. This study recommends appropriate coping strategies and interventions in the construction industry such as education of construction personnel on the consequences of various coping strategies.
文摘Personal factors could act as intervening variables between the causes and effects of psychological health conditions of employees. This study focused on six personal intervening factors that were associated with the risks of occupational psychological disorders namely: low self-esteem, negative personality trait, unproductive core beliefs, poor self-concept evaluation on performance, poor relationship with others and poor time management skills. An investigation on the level of severity of these personal intervening factors was conducted involving 150 construction professionals and 150 construction trade workers, who were purposively selected in Ghana. The personal factors that were found to be prevalent among the construction employees were low self-esteem and poor time management skills. Correlation analysis and regression analysis were used to determine the relationships between the personal intervening factors and demographic factors such as the age, educational levels and marital status of the research participants. The results of the study indicated that the age and marital status of the respondents had no significant relationship with any of the personal intervening factors. Personal factors such as personality trait and relationship with others also had no relation with any of the demographic factors analyzed. The educational level of the respondents, however, had a significant relationship with the factors of self-esteem, productive core beliefs, self-evaluation on performance and time management skills. An independent two-sample T-test was used to compare the means of the factors with significant relations. This study revealed that construction employees who were highly educated had better self-esteem and time management skills than those who were less educated. The findings from this study broaden the view of moderators on influential sources of psychological health conditions of employees.
文摘Purpose: Our study aimed to evaluate the psychological impact of COVID-19 pandemic on Chinese patients with common mental disorders in primary care in Hong Kong. Method: A cross-sectional study was conducted on 102 Chinese patients with common mental disorders and being followed up in two public integrated mental health clinics in Hong Kong from 1<sup>st</sup> November 2020 to 31<sup>st</sup> January 2021. Patients would be evaluated about the impact of COVID-19 pandemic on their mood and daily life by using a questionnaire which assessed social distancing effects, financial impact, relationship with family, anxiety and depressive symptoms. The Patient Health Questionnaire-9 (PHQ-9) and General Anxiety Disorder-7 Questionnaire (GAD-7) would also be used to assess patients’ mood symptoms. Factors which were related to COVID-19 pandemic and associated with anxiety or depressive symptoms would be analysed. Results: The mean age of the subjects was 58.0 years and more patients were female (77.5%). There were 84.3% and 72.5% of patients reported their anxiety and depressive symptoms being affected by COVID-19 pandemic respectively. It was found that 17.6% of patients had their income decreased or were unemployed. About one-third (30.4%) of patients indicated that their relationship with their family was worsened while 8.8% was improved. Social distancing was significantly associated with anxiety (p = 0.006) and depressive symptoms (p 0.001) in patients with common mental disorders. Conclusion: There was considerably more psychological impact including an increase in anxiety and depressive symptoms due to COVID-19 pandemic in Chinese patients with existing common mental disorders in primary care. Primary care physicians should raise their awareness of the psychological impact of COVID-19 pandemic on their patients. Our findings shed light on mental health care planning and preventive measures during the COVID-19 pandemic and potential subsequent pandemics.

文摘BACKGROUND The psychological state of patients with post stroke limb movement disorders undergoes a series of changes that affect rehabilitation training and recovery of limb motor function.AIM To determine the correlation between motor rehabilitation and the psychological state of patients with limb movement disorders after stroke.METHODS Eighty patients with upper and lower limb dysfunction post stroke were retrospectively enrolled in our study.Based on Hospital Anxiety and Depression Scale(HADS)scores measured before rehabilitation,patients with HADS scores≥8 were divided into the psychological group;otherwise,the patients were included in the normal group.Motor function and daily living abilities were compared between the normal and psychological groups.Correlations between the motor function and psychological status of patients,and between daily living ability and psychological status of patients were analyzed.RESULTS After 1,2,and 3 wk of rehabilitation,both the Fugl-Meyer assessment and Barthel index scores improved compared to their respective baseline scores(P<0.05).A greater degree of improvement was observed in the normal group compared to the psychological group(P<0.05).There was a negative correlation between negative emotions and limb rehabilitation(-0.592≤r≤-0.233,P<0.05),and between negative emotions and daily living ability(-0.395≤r≤-0.199,P<0.05).CONCLUSION There is a strong correlation between motor rehabilitation and the psychological state of patients with post stroke limb movement disorders.The higher the negative emotions,the worse the rehabilitation effect.
文摘Anxiety and depressive disorders frequently coexist with gastrointestinal and hepatologic conditions.Despite their high prevalence,approach to treating these co-morbidities is not always straightforward.This paper aims to review the current literature into etiology of psychological comorbidities and their treatment in three conditions commonly encountered at gastroenterology outpatient clinics,namely inflammatory bowel disease(IBD),irritable bowel syndrome(IBS) and chronic hepatitis C(HepC).The paper demonstrates that although psychotherapy(and cognitive-behavioural therapy in particular) has been established as an effective treatment in IBS,more studies are needed in HepC and IBD.Antidepressants have been recognized as an effective treatment for psychological and somatic symptoms in IBS and for depression in HepC,but good quality studies in IBD are lacking despite the promising preliminary findings from animal models and case studies.Further studies in this area are needed.
文摘BACKGROUND The coronavirus disease 2019(COVID-19)pandemic is having a great impact on individuals from all over the world,particularly on individuals with mental disorders.Several studies found more pronounced psychiatric symptoms,notably symptoms of depression and anxiety.AIM To assess the situation of patients with serious mental illness(SMI:Affective disorders and schizophrenia)regarding their mental health outcome during the pandemic.METHODS A systematic search using the databases PubMed and MEDLINE was conducted,employing the key words“COVID-19”,“SARS-CoV-2”,“psychiatric/mental disorder/illness”,“affective/mood disorder”,“bipolar disorder”,“(major)depression”,“schizoaffective disorder”,and“schizophrenia”.Studies that had been published up until January 9,2021 were included.Information of studies in languages other than English and German was mostly taken from their English abstracts.RESULTS The literature search concluded in the finding of 36 studies containing relevant clinical data.A general impairment of the mental health of individuals with SMI could be detected,particularly in individuals with affective disorders,as compared to those with schizophrenia.Compared to healthy controls,symptoms of anxiety,depression,and stress were more pronounced in individuals with SMI.Relevant factors found that impacted their mental health were age,resilience,and socioeconomic environment,especially the shortage of mental health services,lack of social support,and inadequate information about COVID-19.CONCLUSION In light of these results,mental health services should be reinforced,notably the use of telemental health services.Furthermore,supplying individuals with SMI with adequate information about the COVID-19 pandemic and increasing their resilience is important.When researching the impact of the COVID-19 pandemic on individuals with SMI,standardization as well as follow-up studies are needed to enable better comparability and understanding.
