ABSTRACT
More and more evidence shows that there is a close relationship between the inflammatory state and coronary heart disease. Inflammatory state triggers the damage of vascular endothelium in the early stage of coronary heart disease and ultimately mediates the formation of atherosclerotic plaque. The mechanism of occurrence and development of heart disease is of great significance. Phlegm is a pathological product formed by the subtle imbalance of the spleen and stomach in the transportation and transformation of water and grain. It is the general summary of a series of abnormally accumulated inflammatory substances， such as low density lipoprotein， inflammatory cells， and inflammatory factors. The nature of Phlegm determines the invasiveness and turbidity of Phlegm. Phlegm invades the meridians， causing damage to the meridians and gradually accumulating， which eventually causes the local meridian damage to aggravate. This process is similar to the persistent damage of the vascular endothelium caused by inflammation. Phlegm blocks the meridians， affects the operation of Qi and blood， causes Qi stagnation and blood stasis， and finally forms the outcome of heart and blood stasis. This process is similar to the mechanism of atherosclerotic plaques formed by continuous inflammatory damage. Heart blood stasis， depression and heat， heat toxin endogenous， forming the syndrome of heat toxin stasis， which is similar to the process of atherosclerotic plaque rupture and thrombosis causing acute cardiovascular events.The formation of Phlegm is rooted in the deficiency of spleen. Based on the ''phlegm，stasis，toxin'' theory， spleen deficiency is the intrinsic pathogenesis of the inflammatory state of coronary heart disease， and the invasion of phlegm， blood stasis of heart， heat and blood stasis are the evolution of inflammatory damage of coronary heart disease. Traditional Chinese medicine differentiation and treatment is based on strengthening the spleen and nourishing Qi to treat the root and removing phlegm and blood stasis， and clearing heat and detoxifying to treat symptoms. The related Chinese medicine compounds， Chinese patent medicines， and single Chinese medicines can reduce the inflammatory indicators of coronary heart disease， thereby improving the prognosis of coronary heart disease.
ABSTRACT
Bipolar disorder （BD） is considered to be mainly related to qi， phlegm， fire and deficiency. Binding constraint of liver qi is the initial cause， while phlegm and qi interact obstruction as well as phlegm and fire interact binding is the key pathogenesis of the transformation between depression and mania， and deficiency of both qi and yin is the main reason of the protracted course of disease. In clinical practice， BD is divided into binding constraint of liver qi pattern， phlegm and qi interact obstruction pattern， phlegm and fire interact binding pattern， and deficiency of both qi and yin pattern， which can be treated with Jinyu Shugan Powder （金玉疏肝散）， Kaiyu Wendan Decoction （开郁温胆汤）， Qingxin Huatan Decoction （清心化痰汤）， and Baihe Shengmai Beverage （百合生脉饮） in their modifications respectively； moreover， Guanye Jinsitao （Herba Hyperici Perforati） is usually used to rectify qi， relieve phlegm and clear heat. It is also suggested to put focus on the prevention and treatment of qi， phlegm and heat simultaneously， and modify the medicinals flexibly in accordance with the pathogenesis evolution and the abnormal exuberance.
ABSTRACT
Autophagy， a mechanism of cell self-protection and self-renewal， is associated with the occurrence and development of lung cancer. Favorable autophagy can slow down the progression of lung cancer， while unfavorable autophagy can promote the progression. Therefore， regulating the level of autophagy is of great significance in the treatment of lung cancer. Healthy Qi deficiency and pathogenic Qi stagnation is an extension of the theory of deficiency and Qi stagnation proposed by the Academician WANG Yongyan. It refers to the pathological process that the abnormal body fluid metabolism caused by Qi deficiency of lung， spleen， and kidney results in phlegm and blood stasis. Lung cancer has the root cause of Qi deficiency of lung， spleen， and kidney and the syndrome of phlegm and blood stasis. The autophagy in lung cancer is interconnected with healthy Qi deficiency and pathogenic Qi stagnation. The Qi deficiency of lung， spleen， and kidney is the key factor for the weakening of favorable autophagy in lung cancer， which inhibits the apoptosis of tumor cells and leads to the accumulation of harmful substances. Phlegm and blood stasis is a direct factor enhancing the unfavorable autophagy in lung cancer， which promotes the autophagic death of normal cells， weakens the immunosuppressive effect of immune cells on tumor cells， and leads to the proliferation and migration of tumor cells. The combination of healthy Qi deficiency and pathogenic Qi stagnation results in the development of autophagy in an unfavorable direction and finally leads to the continuous progression of lung cancer. Therefore， the traditional Chinese medicine （TCM） treatment of lung cancer should follow the principle of reinforcing healthy Qi and expelling pathogenic Qi， removing phlegm and resolving stasis， so as to enhance favorable autophagy while inhibiting unfavorable autophagy. Such therapy can inhibit the proliferation and migration of tumor cells and promote the remission of lung cancer. According to the existing literature， Chinese medicine monomers are mainly used to treat lung cancer by regulating autophagy. The Chinese medicine intervention of autophagy in lung cancer mainly aims to promote the activation of autophagy. This may be because the favorable autophagy weakening caused by the Qi deficiency of lung， spleen， and kidney is the fundamental reason for the development of lung cancer.
ABSTRACT
Autophagy is a lysosome-dependent intracellular degradation process，and it is a key mechanism of diabetic cardiomyopathy （DCM）. Autophagy has dual regulatory effects on DCM. Under physiological conditions，normal autophagy can promote the decomposition of damaged cardiomyocytes and metabolites，so as to reduce the damage of harmful substances to the body and provide energy for cardiomyocytes. Under pathological conditions，the inhibited autophagy of cardiomyocytes will cause the accumulation of damaged cells and metabolites，which will cause damage to cardiomyocytes and eventually aggravate cardiac dysfunction in the patients with DCM. However，the over autophagy of cardiomyocytes will lead to autophagic death of a large number of cardiomyocytes and result in pathological myocardial remodeling and cardiac dysfunction，thus promoting the progression of DCM. Therefore，the restoration of a normal autophagy level is the key means to protect cardiomyocytes and improve the prognosis of DCM. Chinese medicine can regulate autophagy to treat DCM. Specifically，it can promote autophagy （making up for deficiency） or inhibit autophagy （removing excess） to restore the balance of autophagy，thereby alleviating DCM.

ABSTRACT
Atherosclerotic cardiovascular disease is a common disease with high incidence rate and mortality worldwide. Atherosclerosis is an important pathological basis for the formation of ischemic cardiovascular diseases such as cardiovascular disease， which is related to inflammation， oxidative stress， apoptosis， vascular endothelial damage， foam cell formation， platelet activation， and so on， involving mitogen-activated protein kinase （MAPK）， phosphoinositide 3-kinase/protein kinase B （PI3K/Akt）， cyclic adenosine monophosphate/protein kinase A （cAMP/PKA）， Ras homolog gene family member A （RhoA）/Rho-associated coiled-coil containing protein kinase （ROCK）， nuclear factor-kappa B （NF-κB）， and other signaling pathways. In the past few decades， high-intensity statins were mainly used to treat atherosclerosis by reducing blood lipid levels， which usually caused obvious side effects. Therefore， the development of safer and more effective drugs and treatment modes is the focus of research at this stage. In recent years， Chinese medicine has been playing an increasingly important role in the prevention and treatment of cardiovascular diseases in China. There are many studies on the mechanism of Chinese medicine in the prevention and treatment of atherosclerosis， and it is found that a variety of single Chinese medicine regulate the formation process of atherosclerosis by regulating targeted signal molecules. This paper reviewed the research results of related signaling pathways involved in the pathological formation of atherosclerosis and the mechanism of Chinese medicine in the prevention and treatment of cardiovascular diseases， thereby providing references for the clinical treatment of cardiovascular diseases.
ABSTRACT
Objective To explore the impact of four different anesthetic drugs commonly used in animal experi-ments on cardiovascular system in rats.Methods Electrocardiogram ( ECG) and blood pressure were dynamically recor-ded by a BioPac MP150 system after anesthesia.In addition, the blood glucose at different time points and hepatic func-tion, kidney function, cardiac enzymes and electrolytes at the end of the test were collected.Rusults Chloral hydrate caused severe ventricular arrhythmia.Isoflurane had inhibitory effect on the heart rate.Pentobarbital sodium induced a in-crease of ECG P wave.Urethane caused J point elevation of ECG.Blood pressure in the urethane-and pentobarbital sodi-um-treated groups were increased.Chloral hydrate caused CK to be raised, while isoflurane showed the opposite effect on CK and CKMB.Alanine aminotransferase and aspartate aminotransferase in the pentobarbitol sodium and isoflurane groups were decreased.Creatinine in the chloral hydrate, pentobarbital sodium and isoflurane groups were lower, and the serum sodium and potassium were decreased in the four groups.Conclusions Chloral hydrate has obvious effect on the cardio-vascular system, and is not suitable for animal studies on cardiovascular diseases.Pentobarbital sodium, urethane, isoflu-rane can be chosen for animal studies on cardiovascular diseases.
ABSTRACT
This study was aimed to analyze the bioinformatics of proteomics of rat bone marrow mesenchymal stem cells (MSCs) intervened by active principle region of Yang-Xin Tong-Mai Formula (apr-YTF). The latest versions of bioinformatics tools including DAVID (http://david.abcc.ncifcrf.gov/) and GO (http://www.geneontology.org/) were combined to assign a precise function to rat bone marrow MSCs intervened by apr-YTF. KEGG and VISANT were assigned with a precise function to rat bone marrow MSCs intervened by apr-YTF. The results showed that a total of 102 biological processes were mainly involved, with 35 cellular components and 6 molecular functions. These proteins interacted in 3 signal transduction pathways. It was concluded that the following proteins and signal transduction pathways played an important role in the process of apr-YTF inducing BMSCs differentiation into cardiomyocytes. Presenilin-1 and Presenilin-2 were in the Notch signaling pathway. And syntaxin-4 protein was in soluble N-ethylmaleimide sensitive fusion protein attachment protein (SNARE). The apr-YTF played a role on MSCs from multiple sites, with multiple links through different biological processes. The bioinformatics of proteomics can predict action mechanism of traditional Chinese medicine (TCM) from the holism concept. The validation in combination with molecularbiology was a good way for TCM modernization.
