The pharmacologic action of Atractylodis Rhizoma and its effective constituents in digestive system includes mainly anti-ulcer activity,acceleration of gastric emptying,regulation of gastrointestinal propellant movement,antidiarrheat effect,choleretic effect,hepatoprotection,and promotion of digestive and absorptive function.Atractylodis Rhizoma decreases gastric acid secretion via blockade of H2-receptor,and inhibits overexpression of inflammatory cytokines in gastric tissues to produce anti-ulcer effect.Atractylodis Rhizoma increases gastric mucosal blood flow,and improves growth and reparation of gastric mucosa to produce anti-ulcer effect by blockade of 5-TH receptor,and elevating levels of gastrin and trefoil factor in serum and gastric tissues.Atractylodis Rhizoma accelerating gastric emptying and gastrointestinal propellant movement is relative to decreasing release of central corticotropin-releasing factor,and stimulating vagal nerve,and promoting secretion of gastrin and motilin,and inhibiting secretion of vasoactive intestinal peptide,and blocking 5-HT-3receptor,and increasing amount of interstitial cell of Cajal.

Salidroside antagonizes hypoxia,H2O2,hyper-glucose,homocysteine,smoking,orweightlessness-induced endothelial cell injury,and antagonizes the proliferation of vascular smooth muscle cells and vascular adventitial fibroblasts induced by hypoxia,hyper-glucose,noradrenaline,platelet-derived growth factor,or angiotensin Ⅱ,thus produces vascular protection and improves vascular function.Salidroside plays a dual role of vasoconstriction and vasodilation in regulating resistant blood vessel.The vasodilatory effect of salidroside is endothelium-dependent and endothelium-independent.Salidroside antagonizes vascular contraction and injury induced by KCl,CaCl2,noradrenaline,phenylephrine,homocysteine,hyper-glucose,plateau hypoxia,H2O2,and chlorine.Salidroside relieves cerebral vasospasm induced by subarachnoid hemorrhage,and pulmonary hypertension and pulmonary arterial remodeling induced by hypoxia or monocrotaline in rat,attenuates several experimental atherosclerosis,and enhances plaque stability.

In vitro and in vivo animal model experiments have found that salidroside has protective effect for various causes induced injuries in various neurons and brain tissue.Its mechanisms of neuroprotection are multiple:(1)Protecting neurons from apoptotic injury by resisting oxidative stress,preventing intracellular Ca2 + overload,inhibiting caspase-3 activation,and attenuating hypoxia-induced abnormal metabolism of amyloid precursor protein;(2)promoting directional differentiation of stem cells into neurons and inducing neuronal regeneration;(3)promoting erythropoietin stimulating erythroblasts to be differentiated into erythrocytes and decreasing cerebrovascular resistance,and improving cerebral hypoxia-ischemia.Salidroside is expected to be used in the prevention and treatment of cerebral ischemic and neurodegenerative diseases,such as cerebral infarction,Alzheimer's disease,Parkinson's disease,amyotrophic lateral sclerosis,and diabetic encephalopathy.

Oxypeucedanin (OP) 300 and 600mg/kg ig inhibited the increased permeability of intraperitoneal blood capillary induced by ip 0. 7% acetic acid in mice, xylene-induced swelling of mouse ear, retarded gastrointestinal propellant rate of charcoal ink in normal mice,and reduced the incidence and frequency of purging induced by castor oil or senna in mice. These actions were enhanced in a dose-dependent manner. It is suggested that the antidiarrheal effect of OP is relative to its restriction against inflamation and gastrointestinal propellant function.

By increasing the release of Ca2+ from sarcoplasmic reticulum in cardiomyocytes,salidroside elevates myocardial contraction,and by up-regulation of sarcoplasmic reticulum Ca2+-ATPase expression,and down-regulation ofcalcineurin expression to promote Ca2+ return to sarcoplasmic reticulum,salidroside obstructs Ca2+ overload-induced myocardial injury,and improves heart function.Salidroside inhibits lipid peroxidation,and increases activities of enzymatic antioxidants in heart tissue,and inhibits expression of inflammatory cytokines,and mitochondrial permeability transition pore opening,thus blocks myocardial apoptosis,by anti-oxidation and anti-inflammation;salidroside improves myocardial ischemia by up-regulation of hypoxia-inducible factor and vascular endothelial growth factor expression to promote angiogenesis in ischemic myocardium;salidroside improves respiratory function of mitochondria in myocardium by stimulating PGC-1 αt-NRF-1/NRF-2 signaling pathway to produce finally cardioprotective effect.These effects of salidroside are thought that are major mechanism of antagonizing cardiac injury induced by hypoxia,ischemia,ischemic-reperfusion,exhaustive exercise,chemicals,and biologic toxin.

Anti-oxidation of ursolic acid and oleanolic acid antagonizes oxidative stress-induced lipid peroxidation,inflammatory injury,steatosis,and fibrosis in liver tissue.Ursolic acid and oleanolic acid could block static state hepatic stellate cells activation and proliferation,and promote active state hepatic stellate cells apoptosis,thus decrease expression of collagen,and increase decomposition of extracellular matrix,to produce the effect in prevention and treatment of hepatic fibrosis by obstruction of JAK2-STAT3 signal transduction to inhibit NOX activation.Ursolic acid and oleanolic acid induce expression of detoxification enzymes and effiux transporters to reduce serum levels of bile acids and bilirubin,and liver levels of bile acids in cholestatic animal,thus ameliorating cholestatic liver injury and fibrosis.Ursolic acid and oleanolic acid inhibit occurrence and development of hepatic steatosis via decreasing hyperlipidemia to inhibit lipid out of liver accumulating to liver,inhibiting hepatic lipid synthesis,and improving lipid metabolism.

Objective To study the effects of combination therapy (psychological intervention+clopidogrel+aspirin) for coronary heart disease. Methods 88 cases were selected from January 2016 to April 2017 in patients with coronary heart disease in our hospital. In a randomized approach, patients were divided into treatment groups and control groups, with 44 cases per patient. Patients in the control group were treated with aspirin, and the treatment group was treated with a combination therapy (psychological intervention+clopidogrel+aspirin). The treatment effect, angina and adverse reaction were observed and compared. Results Comparing the therapeutic effect of two groups of patients, the treatment group total effective rate was 97.73%, control group total effective rate was 79.55%, significant difference was statistically significant (P<0.05); Compared two groups of patients with angina, the treatment group patients with onset time (4.32±1.18) shorter, longer time interval (5.03 ±1.34), less number of attacks (1.67±0.49), with statistical significance (P<0.05); Compared to the adverse reactions in the two groups, the incidence of adverse reactions in the treatment group was 4.55%, compared with 18.18% in the control group. Statistical significance (P<0.05). Conclusion Psychological intervention in combination with clopidogrel and aspirin enteric-coated metformin hydrochloride in the treatment, in the clinical treatment of patients with coronary heart disease angina pectoris, shows good therapeutic effect, has higher application value.
