ABSTRACT
Abstract Background In 2012, the Neurocritical Care Society launched a compilation of protocols regarding the core issues that should be addressed within the first hours of neurological emergencies - the Emergency neurological life support (ENLS). Objective We aim to evaluate this repercussion through a bibliometric analysis. Methods We searched Scopus on October 2022 for articles mentioning ENLS. The following variables were obtained: number of citations; number of citations per year; number of publications per year; year of publication; research type; research subtype; country of corresponding author and its income category and world region; journal of publication and its 5-year impact factor (IF); and section where ENLS appeared. Results After applying eligibility criteria, we retrieved 421 articles, published from 2012 to 2022. The mean number of citations per article was 17.46 (95% Confidence Interval (CI) = 8.20-26.72), while the mean number of citations per year per article was 4.05 (95% CI = 2.50-5.61). The mean destiny journal 5-year IF was 5.141 (95% CI = 4.189-6.093). The majority of articles were secondary research (57.48%; n= 242/421) of which most were narrative reviews (71.90%; n= 174/242). High-Income countries were the most prominent (80.05%; n= 337/421 articles). There were no papers from low-income countries. There were no trials or systematic reviews from middle-income countries. Conclusion Although still low, the number of publications mentioning ENLS is increasing. Articles were mainly published in journals of intensive care medicine, neurology, neurosurgery, and emergency medicine. Most articles were published by authors from high-income countries. The majority of papers were secondary research, with narrative review as the most frequent subtype.

ABSTRACT
Objective: Review the relationship between Multiple Sclerosis (MS) and the cardiovascular (CV) system, as well as the CV manifestations of the disease and the CV complications of treatment. Methods: We performed a non-systematic review of the main databases, with no time limit. Results: People with MS tend to have a different CV risk than the general population, with a higher prevalence of hypertension, hyperlipidemia, overweight, ischemic heart disease, and peripheral and cerebral artery disease. In addition, cardiac alterations can be present in any part of MS patient care. Furthermore, MS treatments are not innocuous for the CV system and require attention, especially considering fingolimod and mitoxantrone. Discussion: The findings could partially explain the higher mortality rates found in this population. Furthermore, at the onset, dysautonomia symptoms, like postural orthostatic tachycardia syndrome, can be used as a clinical marker of patients at higher risk to evolve from clinically isolated syndrome to MS. Finally, MS not only progress badly when associated with CV risk factors but are also at increased risk of CV morbidity and mortality. Conclusion: Physicians addressing MS patients should be aware of their increased cardiovascular risk and the impact that adequate control of these factors can have on disease progression, patient lifespan, and global care.
Objetivo: Analisar a relação entre a esclerose múltipla (EM) e o sistema cardiovascular (CV), bem como as manifestações CV da doença e as complicações CV do tratamento. Métodos: Foi realizada uma revisão não sistemática das principais bases de dados, sem limite de tempo. Resultados: Pessoas com EM tendem a ter um risco CV diferente da população em geral, com maior prevalência de hipertensão, hiperlipidemia, sobrepeso, cardiopatia isquêmica e doença arterial periférica e cerebral. Além disso, as alterações cardíacas podem estar presentes em qualquer parte do tratamento do paciente com EM. Além disso, os tratamentos da EM não são inócuos para o sistema CV e requerem atenção, especialmente considerando o fingolimod e a mitoxantrona. Discussão: Os achados podem explicar parcialmente as taxas de mortalidade mais altas encontradas nessa população. Além disso, no início, os sintomas de disautonomia, como a síndrome de taquicardia postural ortostática, podem ser usados como um marcador clínico de pacientes com maior risco de evoluir da síndrome clinicamente isolada para a EM. Por fim, a EM não só progride mal quando associada a fatores de risco CV, mas também apresenta um risco maior de morbidade e mortalidade CV. Conclusão: Os médicos que lidam com pacientes com EM devem estar cientes de seu risco cardiovascular aumentado e do impacto que um controle adequado desses fatores pode ter na progressão da doença, no tempo de vida do paciente e nos cuidados globais.
ABSTRACT
Los avances tecnológicos y del conocimiento hicieron que un mayor número de pacientes con enfermedad crónica gastrointestinal pasen de ser atendidos por el pediatra al control por los médicos de adultos durante una de las etapas más vulnerables de la vida: la adolescencia. El Grupo de Trabajo de Transición del Comité de Gastroenterología de la Sociedad Argentina de Pediatría realizó una búsqueda de literatura exhaustiva y convocó a especialistas referentes del país, con el objeto de unificar los criterios basados en la evidencia y la experiencia. De esta manera, se proponen una serie de recomendaciones para todo el equipo de salud (pediatra, gastroenterólogo infantil, nutricionista, gastroenterólogo de adultos, psicólogo, enfermería), incluso para pacientes y familias, que faciliten el proceso de transición y optimicen el seguimiento, el control, la prevención de complicaciones y la calidad de vida de los pacientes con enfermedades crónicas gastrointestinales
Technological advances and the globalization of knowledge have led to a considerable increase in the number of patients with chronic gastrointestinal disease who transition from pediatric to adult care during one of the most vulnerable life stages: adolescence. The Transition Working Group of the Gastroenterology Committee of the Sociedad Argentina de Pediatría conducted an exhaustive literature search and summoned leading specialists in the most frequent chronic pathologies from all over the country to unify criteria based on evidence and experience. As a result, a series of recommendations are proposed for the whole health team (pediatrician, pediatric gastroenterologist, nutritionist, adult gastroenterologist, psychologist, and nurse) including patients and families, to facilitate the transition process, optimize follow-up, prevent complications, and improve the quality of life of patients with chronic gastrointestinal diseases.

Abstract Plasma exchange (PLEX) is a therapeutic apheresis modality in which the plasma is separated from inflammatory factors such as circulating autoreactive immunoglobulins, the complement system, and cytokines, and its therapeutic effect is based on the removal of these mediators of pathological processes. Plasma exchange is well established for various neurological disorders, and it is applied successfully in central nervous system inflammatory demyelinating diseases (CNS-IDD). It mainly modulates the humoral immune system; thus, it has a greater theoretical effect in diseases with prominent humoral mechanisms, such as neuromyelitis optica (NMO). However, it also has a proven therapeutic effect in multiple sclerosis (MS) attacks. Several studies have suggested that patients with severe attacks of CNS-IDD have poor response to steroid therapy but show clinical improvement after the PLEX treatment. Currently, PLEX is generally established only as a rescue therapy for steroid unresponsive relapses. However, there are still research gaps in the literature regarding plasma volume, number of sessions, and how early the apheresis treatment needs to started. Thus, in the present article, we summarize the clinical studies and meta-analyses, especially about MS and NMO, outlining clinical data regarding the experience with therapeutic PLEX in severe attacks of CNS-IDD, the clinical improvement rates, the prognostic factors of a favorable response, and highlighting the likely role of the early apheresis treatment. Further, we have gathered this evidence and suggested a protocol for the treatment of CNS-IDD with PLEX in the routine clinical practice.
Resumo Plasmaférese (PLEX) é um procedimento em que o plasma é separado de fatores inflamatórios como imunoglobulinas autorreativas circulantes, sistema complemento e citocinas, e seu efeito terapêutico se baseia na remoção desses mediadores de processos patológicos. A PLEX está bem estabelecida no tratamento de diversos distúrbios neurológicos, e é utilizada com sucesso em surtos de doenças desmielinizantes inflamatórias do sistema nervoso central (CNS-IDD). A PLEX modula principalmente o sistema imunológico humoral; assim, tem efeito teórico maior em doenças com mecanismos patológicos humorais proeminentes, como a neuromielite óptica (NMO). No entanto tem também efeito terapêutico comprovado em surtos de esclerose múltipla (EM). Estudos sugerem que a corticoterapia é pouco eficaz em pacientes com surtos graves de CNS-IDD, e que estes apresentam melhora clínica após o tratamento com PLEX. Atualmente, a PLEX está geralmente estabelecida apenas como terapia de resgate para surtos não responsivos a corticosteroides. No entanto, há lacunas na literatura sobre a quantidade de troca de volume plasmático, o número de sessões, e o tempo de início da aférese terapêutica. Dessa forma, resumimos neste artigo estudos clínicos e metanálises, especialmente sobre EM e NMO, e delineamos os dados clínicos sobre a experiência com o uso de PLEX em surtos graves de CNS-IDD, as taxas de melhora clínica, os fatores prognósticos para uma resposta favorável, e destacamos o provável papel do tratamento precoce nestes casos. Em um segundo momento, reunimos essas evidências em uma sugestão de protocolo de tratamento de CNS-IDD com PLEX na prática clínica rotineira.

ABSTRACT
Cell metabolomics is an important branch of metabolomics, which could dynamically monitor cell response and metabolic changes after drugs acting on cells, and look for potential biomarkers. Cell metabolomics has been widely used in illustration of disease mechanism, evaluation of drug efficacy and development of new drug through elucidating the pathophysiological mechanism of the disease and the effect of drug treatment intervention. The researches process of cellular metabolomics and its application in central nervous system diseases were reviewed in order to provide theoretical basis for in-depth study of the pathogenesis and prevention and treatment of central nervous system diseases.
ABSTRACT
Dura mater, rich in vasculature and immune cells, is the outermost layer of the central nervous system, and thus acts as the first barrier to protect brain. Meningeal lymphatic vessels and immune cells are main components of dural immunity, which respond to a variety of central nervous system diseases. Meanwhile, compared with brain parenchyma, dura mater communicates more with peripheral tissues and is more susceptible to medical interventions. Therefore, dura mater is a promising target to prevent, diagnose and treat intracranial diseases. Here dural immunity is clarified based on meningeal lymphatic vessels and dural immune cells, and current researches inquiring the role of dural immunity in infectious and immune diseases of central nervous system are summarized.
ABSTRACT
Abstract Objective: Galvanic vestibular stimulation has been evaluated in the context of vestibular rehabilitation. The objective was to identify evidence in the scientific literature about the clinical applications of galvanic vestibular stimulation. Methods: In this systematic review, the articles describing the applications of galvanic vestibular stimulation were extracted from PubMed, Web of Science, MEDLINE, Scopus, LILACS and SciELO databases. The survey was limited to articles published in English, Portuguese and Spanish. All the articles about the clinical applications of galvanic vestibular stimulation were compiled. Repeated articles in the databases, literature review articles, case reports, letters and editorials were excluded. The descriptors included: galvanic vestibular stimulation, postural balance, central nervous system diseases, vestibular diseases, spinal cord diseases and cognition. Results: The search strategy resulted in the initial selection of 994 articles; the reading of titles and abstracts was accomplished in 470 articles and the complete reading in 23 articles. Clinical applications of galvanic vestibular stimulation included Ménière's disease, vestibular neuritis, bilateral vestibular disorders, vestibular schwannoma, Parkinson's disease, ischemic central lesions, motor myelopathies, anxiety disorders, cognition and memory. Conclusion: Galvanic vestibular stimulation has been considered a potentially useful strategy for balance rehabilitation, since it has the effect of stimulating the central connections related to the postural balance, favoring new neuronal synapses that allow the partial or total recovery of postural imbalance.

ABSTRACT Background: During the pandemic, many neurological symptoms have been evaluated as complications of COVID-19 pneumonia. Objective: To investigate the frequency and characteristics of neurological findings, and their effects on the prognosis of patients with COVID-19 pneumonia who consulted with the Neurology department. Methods: Data on 2329 patients who were hospitalized with the diagnosis of COVID-19 pneumonia in our hospital were scanned. The clinical, laboratory and radiological findings relating to treatment of 154 patients who required neurological consultation were retrospectively evaluated by reviewing the clinical notes. Results: The number of COVID-19 pneumonia patients who required neurological consultations while hospitalized in the ICU was 94 (61.0%). The most common symptom among these patients was hyperactive delirium. Mean age, ferritin levels and CRP values of those with delirium were higher, while the mean lymphocyte percentage were lower, than those of the patients without delirium. Epileptic seizures were observed in eight patients without an epilepsy diagnosis. Two patients were diagnosed with GBS and one patient with ICU neuropathy. The D-dimer levels of patients with acute hemorrhagic CVD and the thrombocyte levels of patients with acute ischemic CVD were found to be higher than in patients without acute ischemic CVD. Conclusion: The proportion of patients who required neurological consultations was higher in the ICUs. We observed neurological symptoms more frequently in the advanced age group. There were no significant increases in the incidence of other neurological conditions except delirium, in COVID-19 patients. We think that further studies are needed to support our data.
RESUMO Antecedentes: Durante a pandemia, muitos sintomas neurológicos foram avaliados como complicações da pneumonia por COVID-19. Objetivo: Investigar a frequência e as características dos achados neurológicos e seus efeitos no prognóstico de pacientes com pneumonia por COVID-19 que consultaram o departamento de Neurologia. Métodos: Foram analisados os dados de 2.329 pacientes internados com diagnóstico de pneumonia por COVID-19 em nosso hospital. Os achados clínicos, laboratoriais e radiológicos relativos ao tratamento de 154 pacientes que necessitaram de consulta neurológica foram avaliados retrospectivamente por meio da revisão das anotações clínicas. Resultados: O número de pacientes com pneumonia por COVID-19 que necessitaram de consultas neurológicas enquanto internados na UTI foi de 94 (61,0%). O sintoma mais comum entre esses pacientes foi o delírio hiperativo. A média de idade, os níveis de ferritina e os valores de PCR daqueles apresentando delírios foram maiores, enquanto a porcentagem média de linfócitos foi menor do que em pacientes sem delírios. Crises epilépticas foram observadas em oito pacientes sem diagnóstico de epilepsia. Dois pacientes foram diagnosticados com SGB e um paciente com neuropatia na UTI. Os níveis de dímero D de pacientes com DCV hemorrágica aguda e os níveis de trombócitos de pacientes com DCV isquêmica aguda foram maiores do que em pacientes sem DCV isquêmica aguda. Conclusão: A proporção de pacientes que necessitaram consultas neurológicas foi maior nas UTIs. Observamos sintomas neurológicos com mais frequência em pacientes de faixa etária avançada. Não houve aumentos significativos na incidência de outras condições neurológicas, exceto delírio, em pacientes com COVID-19. Acreditamos que mais estudos são necessários para apoiar nossos dados.
ABSTRACT
ABSTRACT Background: Melanocytic lesions of the central nervous system (CNS) are an infrequent, broad and diverse group of entities, both benign and malignant, found in all age groups, with imaging findings ranging from well-circumscribed focal lesions to diffuse leptomeningeal involvement. On MRI, they are usually distinguished by a high signal on T1WI sequences, given the paramagnetic effect of melanin, thus making it difficult to differentiate among them. Objective: To describe the imaging and epidemiological characteristics of a retrospective series of CNS melanocytic lesions. Methods: MR images of 23 patients with CNS melanocytic lesions diagnosed between January 2012 and June 2018 were analyzed. Results: Most patients were female (14/23; 61%), with a median age of 47 years (range: 3 weeks to 72 years). The primary melanocytic lesions accounted for 8/19 cases (42.1%), which included neurocutaneous melanosis, meningeal melanocytomas and primary malignant melanomas. Secondary melanocytic lesions (metastatic) accounted for 10/19 cases (52.6%). There was one case of a tumor with secondary melanization, from a melanocytic neuroectodermal tumor of infancy. There were also four cases of primary ocular melanomas. The most frequent findings were the cerebral location, high T1WI signal and marked contrast-enhancement. Conclusions: The present review describes the wide variety of melanocytic lesions that could affect the CNS, emphasizing the MRI characteristics. Knowledge of the imaging, clinical and epidemiological characteristics of CNS melanocytic lesions is essential for their correct interpretation, given the significant overlap between lesion features and the variable prognosis.

A la RM se distinguen por la alta señal en la secuencia T1WI, dado el efecto paramagnético de la melanina, haciendo difícil la diferenciación entre ellas. Objetivo: Describir las características epidemiológicas y de de una serie retrospectiva de lesiones melanocíticas del SNC. Métodos: Revisión de imágenes de RM de 23 pacientes con lesiones melanocíticas del SNC diagnosticadas entre enero de 2012 y junio de 2018. Resultados: La mayoría de los pacientes fueron mujeres (14/23; 61%), con edades comprendidas entre las 3 semanas de vida hasta los 72 años. Las lesiones melanocíticas primarias representaron 8/19 (42,1%), incluyendo: melanosis neurocutáneas, melanocitomas meníngeos y melanomas malignos primarios. Las lesiones melanocíticas secundarias (metastásicas) representaron 10/19 casos (52,6%). Hubo un caso de tumor con melanización secundaria (tumor neuroectodermico melanocítico de la infancia). Se incluyeron cuatro casos de melanomas oculares primarios. Los hallazgos más frecuentes fueron la localización cerebral, el aumento de señal T1 y el acentuado realce con el gadolinio. Conclusiones: Se describe la amplia variedad de lesiones melanocíticas encontradas en el SNC, enfatizando sus características a la RM. El conocimiento de sus características imagenológicas, clínicas y epidemiológicas es fundamental para su correcta interpretación, dado la notable superposición entre las presentaciones de las lesiones y lo variable de sus pronósticos.

Procalcitonin, as a biological marker of bacterial infection, has been widely used in clinical diagnosis of various infectious diseases. With the development of basic and clinical research, it has been found that procalcitonin not only plays a cascading and amplifying role in systemic inflammatory response, but also exerts an important effect on assessment, diagnosis, and prognosis in some central nervous system diseases. In this article, "procalcitonin" "bacterial meningitis""marker" and "central nervous system diseases" were used to search the relevant literatures published from 1993 to 2021 in the databases of Pubmed, Wanfang Medicine and China Knowledge Network. The roles of procalcitonin in central nervous system diseases were systemically reviewed for assisting the diagnosis and treatment of central nervous system diseases.
ABSTRACT
Pediatric central nervous system (CNS) immune-related disease is a group of heterogeneous inflammatory conditions mainly affecting CNS. They usually happen in previously healthy individual, with varied clinical manifestations, pathophysiology and genetic changes. Patients require different therapy as well as have different prognosis. Immunotherapy often is helpful to control the disease. With the development of molecular techniques within the recent 10 years, the clinical spectrum and pathogenesis of these neuroinflammatory diseases is being recognized. Further investigations into these diseases are helpful for early diagnosis and targeted immunotherapy, contribute to decrease the mortality and morbidity, then improve the clinical outcome eventually. This study mainly discuss the neuroinflammatory diseases primarily happen in CNS.

RESUMO Objetivos verificar a aplicabilidade do Video Head Impulse Test (vHIT) em doenças do sistema nervoso central (SNC), bem como os resultados encontrados e as doenças descritas. Estratégia de pesquisa revisão integrativa da literatura, em que foi realizada a busca em nove bases eletrônicas de dados, a partir da palavra-chave "video head impulse test". Critérios de seleção foram incluídos estudos que utilizaram o vHIT no diagnóstico de doenças do SNC e excluídos os estudos publicados antes de 2009 e estudos que realizaram outros procedimentos de investigação clínica, ou que aplicaram o teste no diagnóstico de doenças vestibulares periféricas. Resultados a amostra final foi composta por 18 estudos. Os resultados verificados mostraram que o reflexo vestíbulo-ocular (RVO) tem apresentado alterações na população investigada. Foram observados achados sugestivos de acometimento central, tais como ganho ou média de ganho do RVO nos canais semicirculares verticais, inferior aos laterais, ganho aumentado, correlação negativa do ganho com a gravidade da doença na ataxia espinocerebelar tipo 3, ponto de corte de 0,70 e assimetria de ganho menor de 20% para diferenciar neurite vestibular de derrame no ramo medial da artéria cerebelar posteroinferior, ganho normal com provas oculomotoras alteradas, presença de nistagmo espontâneo vertical, além de alterações no RVO com e sem otimização visual, na perseguição sacádica e no teste de desvio de inclinação. Conclusão verificou-se que o vHIT é aplicável quanto a avaliação do RVO de alta frequência em indivíduos com doenças do SNC, uma vez que trouxe evidências clínicas sobre alterações da função vestibular periférica e central nos diferentes quadros neurológicos.
ABSTRACT Purpose To verify the applicability of the Video Head Impulse Test (vHIT) in central nervous system (CNS) diseases, as well as the results found and the diseases described. Research strategy Integrative literature review, in which nine electronic databases were searched using the keyword "video head impulse test". Selection criteria Studies that used the vHIT in the diagnosis of CNS diseases were included, and studies published before 2009, studies that performed other clinical investigation procedures or that concerned the diagnosis of peripheral vestibular diseases were excluded. Results The final sample consisted of 18 studies. The verified results show that the vestibulo-ocular reflex (VOR) has shown alteration in this population. Suggestive findings of central involvement were observed, such as lower gain or average VOR in the vertical semicircular canals than in the lateral ones, increased gain, the negative correlation of gain with disease severity in Spinocerebellar Ataxia Type 3, cutoff point of 0.70, and gain asymmetry of less than 20% to differentiate vestibular neuritis from a stroke in the medial branch of the posteroinferior cerebellar artery, normal gain with altered oculomotor tests, presence of spontaneous vertical nystagmus, as well as alterations in the VOR with and without visual enhancement, in saccadic pursuit, and the tilt deviation test. Conclusion We found that the vHIT applies to the assessment of high-frequency VOR in individuals with CNS diseases since it provided clinical evidence of changes in peripheral and central vestibular function in different neurological conditions

Abstract Tuberous sclerosis (TSC) is a rare disease with multi-systemic involvement, predominantly neurological. Little evidence exists about the anesthetic management of patients with this disorder, particularly in pregnant women. This article discusses a case of a patient with TSC admitted to our hospital for the delivery of a twin gestation. Twenty-four hours after surgery, the patient presented left-side facial-brachial hypoesthesia and headache. A brain CT revealed a right frontal cortical bleeding tumor, which was diagnosed as glioblastoma multiforme. The patient was discharged 15 days after admission and a neurosurgical approach was suggested.

Compared to traditional methods, single-cell sequencing is conducive to analyze the cells composition and heterogeneity and discover scarce cells in CSF. Recent studies of single-cell sequencing in CSF has mainly focused on the neuroinfectious diseases, neurodegenerative and neuroinflammatory diseases, and leptomeningeal metastases (LM), reflecting the superiority and clinical value of single-cell sequencing in CNS diseases and providing new directions for the diagnosis and treatment of CNS diseases.
ABSTRACT
Objective:To identify the risk factors for postoperative central nervous system complications (CNSC) developed in pediatric patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) through determining regional cerebral oxygen saturation (rSO 2C) by near-infrared spectroscopy. Methods:A total of 60 pediatric patients with congenital heart disease undergoing elective orthodontic correction surgery under CPB, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, of both sexes, aged 6-36 months, weighing 5-19 kg, in our hospital from July 2019 to January 2020 were collected.Intraoperative bilateral rSO 2C was monitored continuously by near-infrared spectroscopy.Blood samples were taken from the central vein at 10 min after induction of anesthesia, immediately after CPB, at the end of CPB, on admission to ICU, at 4 and 8 h after entering ICU and at 1, 2 and 3 days after surgery (T 0-8) for determination of the concentrations of serum S100β protein and neuron specific enolase (NSE). At 12 months after surgery, the Pediatric Cerebral Performance Category (PCPC) score was used to evaluate the prognosis of neurological function.The patients were divided into 2 groups according to whether CNSC occurred: CNSC group and non-CNSC group.Multivariate logistic regression analysis was used to identify the risk factors for development of postoperative CNSC in pediatric patients undergoing cardiac surgery under CPB. Results:Two patients were excluded from the study.Eighteen cases developed postoperative CNSC, and the incidence was 31.0%.Compared with group non-CNSC, the minimal rSO 2 was significantly decreased, the maximal difference between pulse oxygen saturation and rSO 2C (da-rSO 2C) was increased, duration of reduction in rSO 2>25% during CPB, duration of rSO 2C<40% during CPB and duration of da-rSO 2C>50% during CPB were prolonged, and concentrations of serum S100β protein and NSE were increased at T 2-T 8 in group CNSC ( P<0.05). The results of logistic regression analysis showed that prolonged duration of reduction in rSO 2C>25% during CPB, prolonged duration of rSO 2C<40% during CPB and prolonged duration of da-rSO 2C>50% during CPB were risk factors for development of postoperative CNSC. Conclusion:Prolonged duration of reduction in rSO 2C>25% during CPB, prolonged duration of rSO 2C<40% during CPB and prolonged duration of da-rSO 2C>50% during CPB are the risk factors for postoperative CNCS developed.
ABSTRACT
@#As a key component of glutamatergic system, metabotropic glutamate receptor 5 (mGluR5) has been extensively involved in the regulation of physiological processes such as synaptic transmission, synaptic plasticity and synaptic excitation/inhibition balance.Over the past few decades, mGluR5 has been found to be closely related to multiple neurological and psychiatric disorders, thus it is of considerable interest as a drug target in the treatment of such disorders.This review summarizes the structure and distribution of mGluR5, its normal physiological function, its pathological roles in related central nervous system (CNS) diseases, as well as the current status of its drug development, in order to provide reference for further investigation.
ABSTRACT
In recent years, researches constituted to show that the occurrence of central nervous system diseases such as Parkinson′s disease, Alzheimer′s disease and multiple sclerosis may have association with the inflammation of central nervous system. The chemokine CX3CL1 is mainly produced by neurons and acts on the central nervous system. After binding to the receptor CX3CR1, by inhibiting the calcium influx induced by NMDA in neurons, it can promote the activation of protein kinase and activate nuclear transcription factor kappa B, reduce the release of inflammatory factors, and stabilize the status of microglia, thus suppress the inflammatory response of the central nervous system and reduce neuronal death, which play a certain role in neuroprotective effect. Therefore, the interaction between CX3CL1 and CX3CR1 is expected to be a new target in the treatment of central nervous system diseases. In this paper, the structure of CX3CL1 and its receptor CX3CR1, the interaction of signal axis and their research progress on central nervous system diseases are reviewed.

Neural stem cells (NSCs) have the potential of self-renewing and differentiation into neurons,astrocyte,as well as oligodentrocyte.Nowadays,neurogenesis and NSCs transplantation have become new strategies for the treatment of nervous system diseases.However,the disadvantages of NSCs transplantation also limit their progress,including low survival rate,difficulty in differentiation,tumorigenesis and difficulty in penetrating scar tissues.It is a novel issue on how to regulate the proliferation and differentiation of endogenous NSCs in adult neurogenesis.Drug-induced endogenous NSCs proliferation and differentiation is the potential strategy for the regenerative medicine,repairing damaged nerves and treating central nervous system diseases.As a traditional medicine in China,Chinese medicine has the characteristics of multi-target,multi-link and multi-channel treatment,and has unique advantages and broad prospects in promoting nerve regeneration.More and more studies have shown that Chinese herbal medicine could indirectly or directly regulate the proliferation and differentiation of NSCs through extracellular signaling pathways (such as Notch,Wnt/β-catenin,the Sonic Hedgehog (Shh) pathway),intracellular transcription factors,together with changing the microenvironment (neurotrophic factor BNDF).In this review,we focus on the traditional Chinese medicine formulae,Chinese patent medicine,single medicine,as well as their monomers,which regulate the proliferation and differentiation of NSCs,so as to provide a new strategy for the prevention and treatment of central nervous system diseases by traditional Chinese medicine.
