Objective: To study the cardioprotective effect of Baitouwen (Pulsatilla chinensis Regel, PR) in isoproterenol (ISO) induced heart failure in mice, and investigated the molecular targets using network pharmacological prediction and experimental validation. Methods: PR were orally administered to ISO induced HF mice for two weeks. The cardiac function was analyzed by echocardiography. Hematoxylin-eosinstaining (HE) was used to evaluate the pathological changes. The PR targets for HF were predicted by bioinformatics analysis tool (BATMAN-TCM). The expression of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and HF related genes Phosphodiesterase (PDEs), were detected by real-time fluorescence quantitative PCR or Immunohistochemical staining in heart tissues. Results: Cardiac hypertrophy was observed after ISO treatment, and hypertrophic cardiomyocytes were arranged in disorder. Moreover, the expression of ANP and BNP gene in myocardium were upregulated (P < 0.05). Treatment of HF mice with PR aqueous extract improved cardiac function characterized by enhanced ejection fraction (EF) and fraction shortening (FS). Furthermore, PR extract also downregulated the expression of ANP and BNP in the heart tissues. Arrangement of cardiomyocytes was also improved. Furthermore, administration of PR group decreased target genes PDE5 and PDE1C expression in the hearts. In addition, PR treatment also improved myocardial fiber distribution and decreased myocardial thickness in the hearts of HF mice. Conclusion: PR treatment may suppress cardiac hypertrophy and improve myocardial function in HF mice via inhibiting the predicted targets PDE5 expression. These results suggest the potential of using PR in preventing the development of HF.

In China, traditional Chinese medicine is widely used in the treatment of ischemic stroke, but its prescription rules needs to be further studied. This paper uses the traditional Chinese medicine inheritance auxiliary system (a software) to analyze the composition rules of a large number of prescriptions for the treatment of ischemic stroke, and discusses the clinical rationality of the new prescriptions. We found that the prescriptions for the treatment of ischemic stroke are mainly composed by herbs for promoting blood circulation and removing blood stasis, dredging collaterals and tonifying deficiency, and some of the new prescriptions are also in line with this characteristic. This paper can provide reference for clinical prescription in the treatment of ischemic stroke and the development of related new drugs.

Objective: To explore the formula principles for “head wind” disease by data-mining and provide reference for the treatment of “head wind” disease. Methods: Prescriptions for headache from “Dictionary of Traditional Chinese Medicine Prescriptions” were collected, sorted and entered into the “Traditional Chinese Medicine Inheritance System” (V2.5) to analyze the composition principles by the methods of revised mutual information, complex system entropy cluster and unsupervised hierarchical cluster. Results: The herbs with high usage frequency in these prescriptions for “head wind” disease included Chuan-xiong, Bai-zhi, Xi-xin, Fang-feng, Gan-cao, Shi-Gao and Qiang-Huo. Three new prescriptions were obtained based on the composition principles and rules. The first new prescription is composed of Quan-xie, Xiong-huang, Jiang-can, Zhi-chuan-wu and Di-long. The second new prescription is composed of Du-huo, Rou-gui, Ku-shen; Fang-feng, Gao-ben, Qiang-huo. The third new prescription is composed of Fu-zi, Sheng-chuan-wu, Tian-nan-xing, Chuan-xiong, Bai-zhi, Shi-gao. Conclusion: We found that the most of herbs used to treat the “head wind” disease are warm and spicy, mainly belong to diaphoretic herbs, wind-expelling herbs, and dampness-dispelling herbs. In addition, the new prescriptions for infertility mainly focus on eliminating evil, with the characteristics of “eliminating phlegm and turbid”, “dredging the channels and collaterals”, “expelling wind-evil” and “promoting blood circulation”.

As a well-known Chinese medicine prescription, Wenxin Keli (WXKL) has been widely used in the treatment of many arrhythmias including atrial fibrillation and has achieved significant clinical effects, but the specific mechanism of its treatment of atrial fibrillation remains unclear. This study used a network pharmacology approach to reveal the potential molecular mechanisms of WXKL in the treatment of atrial fibrillation. It involves oral bioavailability screening of ingredients, drug-likeness evaluation, compound target fishing, H-C-T network and C-T-P network construction and analysis. Through the network pharmacology-based research strategy, the complex system of WXKL was analyzed. It was found that 14 representative compounds of WXKL, 30 protein targets and 12 related signaling pathways help us systematically understand the underlying mechanism of WXKL's anti-atrial fibrillation effects.

Objective: The protective effects of curcumin on myocardial ischemia-reperfusion were systematically evaluated by analyzing the related literatures of curcumin and myocardial ischemia-reperfusion. Methods: The computer was searched for Wanfang, VIP, China National Knowledge Infrastructure(CNKI), SinoMed, and Pubmed database to find animal experiments on curcumin treatment of myocardial ischemia-reperfusion.The retrieval time is from the establishment of the database to November 2018. Two researchers independently screened the literature based on inclusion and exclusion criteria, extracted the data, and assessed the risk of bias in the included studies. Meta analysis was performed using RevMan 5.3 software. Results: Finally, 9 studies were included for analysis. Meta-analysis showed that the curcumin group can reduce LDH and MDA levels compared with the ischemiar-reperfusion group  (LDH: SMD=-4.75, 95% CI [-6.56, -2.94], P < 0.01, MDA: SMD=-2.27, 95% CI [-3.07, -1.47], P < 0.01), the difference was statistically significant (P<0.01). In the subgroup analysis of different doses of curcumin, different doses of curcumin (0.8, 10, 12.5, 20, 25, 30, 50 mg) were able to reduce LDH content compared with the ischemia-reperfusion group, and the differences were statistically significant. Different doses of curcumin (5,10,20,30,40mg) can reduce MDA content, and the difference is statistically significant; curcumin (0.8mg) group has no statistically significant effect on MDA content (SMD = -0.54, 95% CI [-1.35, 0.28], P = 0.20). The relationship between the content of MDA and the dose of curcumin showed that compared with the curcumin (20 mg) group, the curcumin (40 mg) group could better reduce the MDA content, and the difference was statistically significant (P=0.03). Conclusion: Curcumin can reduce the content of LDH and MDA in myocardial ischemia-reperfusion,  and has a protective effect on myocardium. Moreover,  the ability to reduce the damage is related to the dose of curcumin. However, the sample of the included studies is limited, and this conclusion requires more high-quality experiments to verify.

Highlights

This review provides evidences for the recommendation of acupuncture preconditioning at Neiguan (PC6) point in coronary heart disease patients as a non-pharmacological therapeutic method to activate the miR-214/NCX1 pathway.

Traditionality

The concept of acupuncture preconditioning is described in the ancient book of Fan Wang Fang (Eastern Jin Dynasty of China). It refers to the application of acupuncture before the occurrence of disease or when the disease is relatively mild. According to the record of the ancient book of Huang Di Nei Jing (Qin Han Period of China, 475 B.C.-221 B.C.), acupuncture at Neiguan (PC6) point can prevent and treat angina pectoris in coronary heart disease (CHD). The WHO also recommends acupuncture as one of the alternative and complementary therapies for the prevention and treatment of angina pectoris in CHD.

Abstract

Early reperfusion of ischemic cardiac tissue is usually the best option to improve clinical outcome of angina pectoris, especially of acute myocardial infarction. However, myocardial reperfusion may cause an abnormal increase of intracellular Ca2+-mediated cardiomyocyte death and consequent loss of cardiac function, which is referred to myocardial ischemia/reperfusion (I/R) injury. Recently, the microRNA-214 (miR-214)/Na+/Ca2+ exchanger (NCX) 1 co-expression is a key factor in cellular protection against myocardial apoptosis for myocardial I/R injury. Once activated, miR-214/NCX1 axis can inhibit several Ca2+ downstream signaling effectors that mediate cell death simultaneously. Studies have shown that acupuncture preconditioning has a protective effect on myocardial I/R injury, but its mechanism deserves further research. It has been proved that acupuncture preconditioning for ischemic myocardium successfully inhibit multiple Ca2+ handling related microRNAs that mediate cell death pathways, and miR-214 is one of its targets. In terms of clinical practice, coronary heart disease (CHD) patients benefit a lot from this intervention. However, there is barely no study correlating acupuncture preconditioning to the miR-214/NCX1 co-expression in patients with CHD. This review aims to discuss whether there is some evidence to justify a recommendation of acupuncture preconditioning in CHD patients as a non-pharmacological therapeutic method to activate the miR-214/NCX1 co-expression network model.

Intracranial vascular stenosis is closely related to transient ischemic attack (TIA) and cerebral infarction, early prevention and treatment of intracranial vascular stenosis can prevent cerebral infarction and improve the prognosis of stroke. Western medicine employs interventional surgery or vasodilator, antiplatelet drugs, lipid lowering drugs, plaque-stabilizing agents and other drugs for treating intracranial vascular stenosis. No corresponding disease name with “intracranial vascular stenosis” is found in Chinese medicine literature. Based on the characteristics of syndromes, symptoms and diseases, “intracranial vascular stenosis” is summarized as weakened body resistance and prevailed pathogenic factors, phlegm with blood stasis and “obstruction (Bi) syndrome” in the brain. The self-made Chinese herbal “Naomaitong” prescription treating for bilateral middle cerebral artery stenosis in 1 case got satisfactory efficacy by transcranial doppler (TCD) and computed tomography angiography (CTA) examination.

Highlight

“Intracranial vascular stenosis” has no corresponding name in Chinese medicine literature. The writer summarized it as vessel impediment which location was in the brain with weakened body resistance and pathogenic stagnation, phlegm with blood stasis, based on the characteristics of its symptoms, syndromes and disease. The present study suggested the self-made Chinese herb “Naomaitong” prescription treating for bilateral middle cerebral artery stenosis can get satisfactory effect in clinic.

Atrial fibrillation is of public health importance and profoundly increases morbidity, mortality and health-related expenditures. Morbidities include the increased risks of cardiovascular outcomes such as heart failure and stroke, and the deleterious effects on quality of life, functional status and cognition. Our purpose is to understand the molecular mechanism of atrial fibrillation, a model under pathological conditions should be established. Acetylcholine, a neurotransmitter in the vagus nerve, has been established with numerous atrial fibrillation models. We will discuss the established model of atrial fibrillation which induced by acetylcholine, aiming to seek a model which are more close to the clinical condition. The underlying mechanisms will be discussed in order to observe the mechanism of antiarrhythmic drugs.

Highlight

Acetylcholine as a neurotransmitter of the vagus nerve which plays an important role in the occurrence and maintenance of atrial fibrillation, is important in basic researches. The acetylcholine is another novel candidate target for atrial-specific drug therapy. The constitutively active form of this current increased in human atrial fibrillation and pharmacological inhibition might be of therapeutic value.
