The naturally-occurring dipeptide carnosine (beta-alanyl-L-histidine) is found exclusively in animal tissues, such as brain and skeletal muscle tissues. Carnosine is a potent hydrophilic antioxidant, antiglycating agent, reactive oxygen species scavenger and pH-buffer. Recent reports suggest that carnosine has potential therapeutic applications in many diseases of central nervous system, such as Alzheimer's disease, Parkinson's disease and cerebral ischemic diseases. To investigate the relationship between carnosine and diseases of central nervous system, and to research and develop carnosine drugs will shed light on a new way for treatment of diseases of central nervous system.

Investigating the pathophysiological mechanisms underlying brain disorders is a priority if novel therapeutic strategies are to be developed. In vivo studies of animal models and in vitro studies of cell lines/primary cell cultures may provide useful tools to study certain aspects of brain disorders. However, discrepancies among these studies or unsuccessful translation from animal/cell studies to human/clinical studies often occur, because these models generally represent only some symptoms of a neuropsychiatric disorder rather than the complete disorder. Human brain slice cultures from postmortem tissue or resected tissue from operations have shown that, in vitro, neurons and glia can stay alive for long periods of time, while their morphological and physiological characteristics, and their ability to respond to experimental manipulations are maintained. Human brain slices can thus provide a close representation of neuronal networks in vivo, be a valuable tool for investigation of the basis of neuropsychiatric disorders, and provide a platform for the evaluation of novel pharmacological treatments of human brain diseases. A brain bank needs to provide the necessary infrastructure to bring together donors, hospitals, and researchers who want to investigate human brain slices in cultures of clinically and neuropathologically well-documented material.

Precious Tibetan medicine formula is a characteristic type of medicine commonly used in the clinical treatment of central nervous system diseases. Through the summary of modern research on the precious Tibetan medicine formulas such as Ratnasampil, Ershiwuwei Zhenzhu Pills, Ershiwewei Shanhu Pills, and Ruyi Zhenbao Pills, it is found that they have obvious advantages in the treatment of stroke, Alzheimer's disease, epilepsy, angioneurotic headache, and vascular dementia. Modern pharmacological studies have shown that the mechanisms of precious Tibetan medicine formulas in improving central nervous system diseases are that they promote microcirculation of brain tissue, regulate the permeability of the blood-brain barrier, alleviate inflammation, relieve oxidative stress damage, and inhibit nerve cell apoptosis. This review summarizes the clinical and pharmacological studies on precious Tibetan medicine formulas in prevention and treatment of central nervous system diseases, aiming to provide a reference for future in-depth research and innovative discovery of Tibetan medicine against central nervous diseases.

Neurodegenerative diseases are a collective term for a large group of diseases caused by degenerative changes in nerve cells. Aging is the main risk factor for neurodegenerative diseases. The neurovascular unit(NVU) is the smallest functional unit of the brain, which regulates brain blood flow and maintains brain homeostasis. Accelerated aging of NVU cells directly impairs NVU function and leads to the occurrence of various neurodegenerative diseases. The intrinsic mechanisms of NVU cell aging are complex and involve oxidative stress damage, loss of protein homeostasis, DNA damage, mitochondrial dysfunction, immune inflammatory response, and impaired cellular autophagy. In recent years, studies have found that traditional Chinese medicine(TCM) can inhibit NVU aging through multiple pathways and targets, exerting a brain-protective effect. Therefore, this article aimed to provide a theoretical basis for further research on TCM inhibition of NVU cell aging and references for new drug development and clinical applications by reviewing its mechanisms of anti-aging, such as regulating relevant proteins, improving mitochondrial dysfunction, reducing DNA damage, lowering inflammatory response, antioxidant stress, and modulating cellular autophagy.

In recent years, more and more research shows that the pharmacokinetic parameter of traditional Chinese medicine can be affected by the disease states. It's possible that drug metabolic enzymes, transporters, cell membrane permeability and the change of microbes group could be interfered with physiological and pathological changes, which enables the pharmacokinetics of traditional Chinese medicine in the body to be altered, including the process of absorption, distribution, metabolism and excretion, and then the pharmacokinetic parameters of traditional chinese medicine are altered. It's found that investigating the pharmacokinetic of traditional Chinese medicine in the pathological state is more useful than that of in normal state because the great part of traditional Chinese medicine is mainly used to treat disease. This article reflects the latest research on the pharmacokinetic of traditional Chinese medicine in the disease state such as diabete, cerebral ischemia, liver injury, inflammatory disease, nervous system disorders and fever in order to provide certain reference for clinicians designing reasonable administration dose.

B-type natriuretic peptide (BNP) is a plasma marker of left ventricular dysfunction and cardiac volume overload. Currently it is mainly used in the cardiovascular field. BNP is an intrinsic regulator of the embryonic stem cell proliferation, and the reduction in BNP can increase the apoptosis rate. The epitope of N terminal pro-brain natriuretic peptide-BNP is most stable. BNP1-32 has the strongest biological activity but with lower plasma level in heart failure patients. The plasma BNP level plays an important role in the diagnosis, prognosis, hospital admission and mortality of heart failure, and can be used as a monitoring indicator in the treatment of heart failure. The deficiency of corin enzyme in patients with heart failure can cause the increase of cracking pro-BNP. BNP can also provide diagnostic and prognostic information for other populations and diseases. Genetic studies on BNP and its receptors also provide important information. Nesiritide, neutral endopeptidase inhibitors, and vasopeptidase inhibitors of the natriuretic peptide synthesis have been used for the treatment of cardiovascular disorders. However, more reliable and accurate approaches for detecting BNP and N terminal pro-brain natriuretic peptide-BNP require further investigations.

Neuroinflammation is a key contributor to the pathogenic cascades induced by hypoxic-ischemic (HI) insult in the neonatal brain. AD-16 is a novel anti-inflammatory compound, recently found to exert potent inhibition of the lipopolysaccharide-induced production of pro-inflammatory and neurotoxic mediators. In this study, we evaluated the effect of AD-16 on primary astrocytes and neurons under oxygen-glucose deprivation (OGD) in vitro and in mice with neonatal HI brain injury in vivo. We demonstrated that AD-16 protected against OGD-induced astrocytic and neuronal cell injury. Single dose post-treatment with AD-16 (1 mg/kg) improved the neurobehavioral outcome and reduced the infarct volume with a therapeutic window of up to 6 h. Chronic administration reduced the mortality rate and preserved whole-brain morphology following neonatal HI. The in vitro and in vivo effects suggest that AD-16 offers promising therapeutic efficacy in attenuating the progression of HI brain injury and protecting against the associated mortality and morbidity.

Many active ingredients in traditional Chinese medicine exist in the form of glycosides. In recent years, the problem of low bioavailability of Chinese glycosides has caused wide public concern. Glycosides and their metabolites organization distribution directly affect glycosides' curative effect after different ways administration. With reports of glycosides medicine for prevention and treatment of brain diseases increasing, the research of glycosides brain tissue distribution is particularly important. According to reports, glycosides widely distributed in tissues, some glycosides can reach the brain, but some glycosides can not. This research reviews glycosides and their metabolites on the role of brain diseases, the distribution in the brain tissue and recent reports of dosage form's effect to brain. So it can provide a reference for the period of such medicine in the prevention and treatment of brain diseases and drug development.
