Progress on the Pathogenesis and Treatment of Alzheimer’s Disease

Background: Alzheimer’s disease (AD), commonly known as senile dementia, is a neurodegenerative disease with clinical manifestations of memory impairment, personality and behavior changes. The pathogenesis of AD is complex and inconclusive in the point of view of western medicine, which is the fundamental reason for the lack of drugs that can reverse the course of the disease. People have gradually shifted from simple amyloid hypothesis to new pathogenesis theories, such as gamma oscillation, prion like transmission, and so on. As an effective means to treat AD, traditional Chinese medicine has made some research progress in recent years. This article mainly reviews the etiology, pathogenesis and treatment of AD, so as to provide reference for the prevention and treatment of AD. Methods: Through systematic literature research, comparison and analysis, the main pathogenesis, influencing factors, progress and development tendency of traditional Chinese medicine and Western medicine in the treatment of AD are presented. Results: Alzheimer’s disease is a kind of multiple neurodegenerative diseases. The pathogenesis and related targets of AD still need to be further explored. The main pathological phenomenon of AD is senile plaques formed by intracellular neurofibrillary tangles and extracellular amyloid protein aggregation. Existing possible pathogenesis includes β-amyloid cascade hypothesis, tau protein hypothesis, cholinergic hypothesis and so on. As the pathogenesis of AD has not been clarified, so far no effective therapeutic drugs or means have been found. The traditional drugs used to treat AD mainly include acetylcholinesterase inhibitor kabbalatin, galantamine, donepezil, and N-methyl-D-aspartate receptor antagonist memantine. However, although these marketed drugs can slow down the course of the disease and alleviate symptoms, they cannot totally cure the disease. Traditional Chinese medicine has the characteristics of personalized differentiation and treatment. The Western medicine can accurately determine the lesion location and target. Conclusions: Integrated traditional Chinese medicine and West medicine is the most promising direction in the treatment of Alzheimer’s disease.

Progress on the Pathogenesis and Treatment of OCD, AD and Depression

Background: Obsessive-compulsive, anxiety disorder, and depression are the most common negative emotions. The incidence rate is high and spread across all age groups. With the rapid development of the world economy and the increasing competition in social life, the incidence rate has also increased rapidly, more and more young suffer from these three kinds of mental illnesses. Many studies have been carried out to investigate the pathogenesis and therapeutic method. It is necessary to summarize the progress for references to further research and treatment. Method: Based on a series of literature, the studies on the pathogenesis and therapeutic method of the three kinds of illnesses are summarized and analyzed. The points and results either of West medicine (WM) or traditional Chinese medicine (TCM) are collected and compared to find the best tendency of study and the best therapeutic method. Results: Obsessive-compulsive disorder, anxiety disorder and depression are common in recent years and severely affect people’s lives. In view of WM. These three kinds of illnesses are all related to the changes or damage of part of brain and nervous system. While TCM thinks that they are due to Qi stagnation or deficiency of heart Yin. Many methods of treatment have been presented and used clinically, but the effect is limited. Conclusion: The most promising and effective methods are those combining WM and TCM.

On the Blood Pressure in the Cardiovascular System

Background: Hemodynamics is a practical and complicated theoretical problem. The aim of this paper is to analyze the characteristics of blood pressure in the cardiovascular system changing with the mechanical parameters of blood vessels and the storage of some visceral organs. Method: The fluid network model was used for the study. The cardiovascular system was modeled as a system consisting of 20 segments of vessels. The main controlling parameters were determined first by using dimensional analysis. Then the responses of blood pressure of each segment of vessels were analyzed by changing the controlling parameters. Results: The parameters of the blood vessel of brain have the least influence on the pressures of other parts. The pressures of the system of blood vessels will decrease if some blood is stored in the liver or the abdominal vein system. Vice versa. The effects of regulation of blood on the variation of blood pressure are larger than the other controlling parameters. Conclusions: The controlling parameters of the abdominal aorta and ascending aorta affect greatly the blood pressure of each vessel.
