Neurodegenerative diseases are chronic and progressive diseases of the nervous system.Modern studies have shown that intestinal flora disorders,mitochondrial dysfunction and lipid metabolism abnormalities are closely related to the occurrence and development of neurodegenerative diseases,but the treatment methods are limited.Traditional Chinese medicine believes that spleen is the"the foundation of nurture"and the"the source of Qi and blood biochemistry",Qi deficiency leads to insufficient Qi,blood and body fluid metaplasia,brain dysplasia,leading to the occurrence of neurodegenerative diseases.This paper discusses the mechanism of treating neurodegenerative diseases by spleen from the perspective of"intestinal flora,mitochondria and lipids",and concludes that intestinal flora balance is the material basis of spleen function,mitochondrial homeostasis is an important mechanism of the function of"spleen governing transportation and transformation",and abnormal lipid metabolism is an important manifestation of spleen deficiency and phlegm stasis.Intestinal flora,mitochondria and lipid metabolism may be the potential biological basis for the treatment of neurodegenerative diseases by spleen in traditional Chinese medicine.In order to provide ideas for the clinical research and treatment of neurodegenerative diseases.

Cerebral ischemia reperfusion injury(CIRI)is a secondary brain injury that may occur in patients with ischemic stroke during the process of blood flow recovery.NOD-like receptor protein 3(NLRP3)inflammasome plays an important role in the occurrence and development of CIRI.Regulating the activity of NLRP3 inflammasome can induce cell pyroptosis,induce neuroinflammatory response,promote macrophage/microglial polarization,destroy the blood-brain barrier,affect angiogenesis and neurogenesis,thereby affecting CIRI.Traditional Chinese medicine has obvious advantages in the treatment of CIRI.In this paper,with NLRP3 inflammasome as the core,we systematically elucidated the mechanism of action of traditional Chinese medicines on CIRI,and found that traditional Chinese medicines monomers(such as baicalin,polygalasaponin F)and traditional Chinese medicines compound formulas(such as Huangqi guizhi wuwu decoction,Yiqi shengqing formulation)can inhibit NLRP3 inflammasome activity,reduce inflammatory response and oxidative stress,and improve neuronal injury,thereby reducing CIRI.

Ischemic stroke is the leading cause of disability in China,and treatment options are still very limited.The method of dredging Fu-organs has been proved to have a significant effect in the treatment of ischemic stroke,but its mechanism is not clear.With the progress of brain-gut communication research,more and more evidence shows that brain-gut communication plays an important role during ischemic stroke.Based on the theory of"brain-gut interaction",this paper discusses the mechanism of Tongfu method in the treatment of ischemic stroke,and discusses the intestinal flora,brain-gut peptide,intestinal metabolites,intestinal mucosal barrier and other aspects.It is concluded that Tongfu method can treat ischemic stroke by regulating intestinal flora,brain-gut peptide content,intestinal metabolite content and repairing intestinal mucosal barrier.In order to provide more ideas for elucidating the mechanism of Tongfu method in the treatment of ischemic stroke,it has very important theoretical and clinical value.

Cerebral ischemia-reperfusion injury(CIR1)refers to the recovery of blood supply after cerebral ischemia,which leads to further damage and the dysfunction of brain tissue.Modern medicine has made some progress in the prevention and treatment of CIRI,but it still faces some challenges and limitations.Therefore,it is of great clinical value to find effective interventions to prevent and treat CIRI.AMP-activated protein kinase(AMPK)and its downstream proteins are important targets for the treatment of CIRI and play key roles in the regulation of cellular energy homeostasis.Traditional Chinese medicine for CIRI has multi-target and multi-pathway activities and multiple effects.It can activate a cascade of reactions in the AMPK signaling pathway and can be used to treat CIRI by regulating autophagy,oxidative stress,inflammatory response,and apoptosis,and has achieved certain result.Therefore,this paper summarizes the structure and mechanisms of the AMPK-related signaling pathway,elaborates on its relationship with CIRI,and systematically summarizes the research status of traditional Chinese medicine's ability to regulate the AMPK signaling pathway in the prevention and treatment of CIRI.This paper aims to provide new ideas for the prevention and treatment of CIRI using traditional Chinese medicine and the development of new drugs.

Microglia efferocytosis,the process by which microglia phagocytose damaged and dead cells,has anti-inflammatory and pro-damage repair effects.Recent studies have shown that microglia efferocytosis plays a crucial role in the pathogenesis of Alzheimer's disease(AD)and may be a novel therapeutic target for AD.This paper reviews the relationship between microglia efferocytosis and AD pathogenesis and the potential of using efferocytosis-related molecules as therapeutic targets for AD.The aim of this review is to provide new ideas and approaches for the treatment of AD.

Objective To report the clinical features,microsurgical techniques and outcomes of 5 patients admitted in our hospital,who had solid hemangioblastoma in medulla oblongata in the last 5 years.Methods 5 consecutive cases of solid hemangioblastoma in medulla oblongata operated from March,2011 to May,2016 were reviewed and fl lowed up.Results All patients suffered headache,dizziness and cerico-occipital pain from the beginning plus one was found because of obstructive hydrocephalus.The mean duration before operation was 6.7 months.The mean maximum diameter of tumor was (33.7±3.4)mm.The suboccipital posterior midline approach was performed and gross total resection was achieved in all 5 cases.After operation,endotracheal tube was removed in all 5 patients,but 3 received tracheotomy,and all patients can take food freely now through rehabilitation exercise.Followed up until September 2016,all patients lived a normal life.Conclusion The operation of solid hemangioblastoma in medulla oblongata is full of huge risk,but microsurgical resection is the only cure means for the tumor.

Objective There are differences in the diagnosis and treatment of primary melanocytoma in central nervous sys -tem.The article was to investigate the experience of its diagnosis and treatment . Methods Retrospective analysis were made on the clinical data of 14 cases with primary melanocytoma in central nervous system ( CNS) from January 1999 to December 2012, among which were 5 males and 9 females.The incidence ages were 14-52, average 32.7.The course of disease ranged from half a month to 19 years, geometric average 7.9 months.5 cases recurred and 9 cases occurred first.10 cases were intracranial and 4 were intraspinal. Results 14 patients underwent surgery and had pathologic diagnosis of melanocytoma .Total resection was performed in 7 patients, subtotal resection in 3, and partial resection in 1.Immunohistochemical study showed , in all cases, S-100 and HMB-45 were positive, GFAP and EMA were negative .Vimentin was positive in 8 cases and MelanA positive in 5 cases.12 cases recovered well and dis-charged except for paraplegia and facial paralysis in 1 case each. Conclusion Primary melanocytoma in CNS is very rare .Diagnosis is based on intraoperative findings , surgical pathology and immunohistochemistry results .Surgery is the primary therapy and early total resection is advocated .Adjuvant radiotherapy can reduce the recurrence rate .
