A summary of research on benefiting Qi and activating blood to regulate mitophagy to prevent and treat ischemic heart disease

Ischemic heart disease has the characteristics of high morbidity and high mortality, which seriously endangers people's health. Mitophagy can selectively remove damaged organelles, and has a role in maintaining the homeostasis of myocardial cells and protecting ischemic myocardium. Significance. More and more studies have found that traditional Chinese medicine can improve ischemic damage of cardiomyocytes by regulating mitochondrial function and autophagy. Using mitochondria as the target of traditional Chinese medicine in cardiomyocytes to explore the treatment of ischemic Effective measures for heart disease have become a hotspot for related Chinese medicine workers. Based on the above background, this article outlines the main regulatory pathways of mitochondrial autophagy, and reviews related researches on traditional Chinese medicine of benefiting qi and activating blood and mitophagy in this field.

Astragalus Salvia Granules to Benefit the Qi (Qishen Yiqi Keli) protects H9C2 cardiomyocytes by suppressing oxidative stress

Objective:To investigate the effects of Qishen Yiqi Keli(QSYQ;Astragalus Salvia Granules to Benefit the Qi)on ROS scavenging and inhibition of NADPH oxidase in an effort to identify new natural antioxidants.Methods:A total of 23 representative components in QSYQ were investigated,their effects on hydrogen peroxide induced ROS were assayed by dichlorofluorescein assay.Lucigenin chemiluminescence was adopted to test the effect on NADPH oxidase activity in H9C2 cardiomyocyte cells,and pyrogallol autoxidation was adopted to test the superoxide scavenging capacity.Results:Nine compounds in QSYQ could significantly inhibited H2O2-induced ROS increase compared with the model group(P<.05),including tanshinone I,salvianolic acid A,danshinone IIA,and cryptotanshinone from salvia root,luteolin from salvia root,harpagoside,harpagide,and angoroside C from scrophularia root.Nine compounds in QSYQ could significantly inhibited the production of
O2in H9C2 cell.Tanshinone I showed a lowest IC50 value 0.07 mM,the other including salvianolic acid A,cryptotanshinone,and salvianolic acid B,luteolin,isochlorogenic acid C,astragaloside IV,and glycyrrhetinic acid.Licochalcone A inhibited the autoxidation of pyrogallol at a low concentration,and tanshinone I showed no significant inhibitory effect from 2 mM to 20 mM.Conclusion:QSYQ had significant effects on ROS scavenging and inhibition of NADPH oxidase.Tanshinone I and salvianolic acid A are potential NADPH oxidase inhibitors.

Case of professor Xu ZOU’s acupuncture technique for“benefiting kidney and strengthening anti-pathogenic qi”in promoting the absorption of COVID-19

A case of the absorption of corona virus disease 2019(COVID-19)promoted by professor Xu ZOU’s acupuncture technique for"benefiting kidney and strengthening anti-pathogenic qi"is introduced.A female patient suffered from COVID-19,64 years old,had been treated with acupuncture and Chinese herb granules for 10 days on the base of the oral administration of moxifloxacin.In the re-examination,the chest CT image indicated that the absorption of COVID-19 was obvious as compared with before,the nucleic acid test of novel corona virus was negative and the patient narrated no obvious discomfort.Acupuncture therapy plays its active adjuvant effect in the whole process of the treatment of COVID-19.

Effect of Yiqiyangyin recipe on heparanase and nephrin in rats with adriamycin-induced nephropathy

OBJECTIVE： To discuss the mechanism of Yiqiyang- yin recipe in rats with adriamycin （ADR）-induced ne- phropathyo METHODS： We randomly divided 30 Sprague-Daw- ley rats into 5 groups： control, model, glucocorti- coid, Chinese herb, and Chinese herb plus glucocor- ticoid groups. The 24-h urine volume was collected on days 7, 14, 21, and 28 after ADR injection, and all rats were killed on day 28. We measured the 24-h levels of urinary protein, serum cholesterol, and se- rum triglycerides, and renal function of all rats by using routine biochemical methods. Pathological changes in the rat kidneys were observed under light and electron microscopes. Heparanase （HPA） mRNA expression levels were measured using re-al-time fluorescence-quantitative polymerase chain reaction. Urine levels of HPA in all groups were measured using enzyme-linked immunosor- bent assay. The expression of nephrin was detected by immunohistochemical staining and quantitative- ly analyzed using Motic image analysis 3.2 software. RESULTS： The levels of urinary protein and serum triglycerides and cholesterol in rats with ADR-in- duced nephropathy increased on day 14. The se- rum albumin levels simultaneously decreased. All the changes reached the peak on day 28. Examina- tion under the light microscope showed inflamma- tory cells and slight fibroplasia in the renal intersti- tium in the model group, but fewer inflammatory cells were observed in the intervention groups than those in the model group. Examination under the electron microscope showed extensive fusion of foot processes in ADR rats. HPA mRNA expres- sion was higher in the model group than that in the control group. The HPA mRNA levels in the in- tervention groups, especially in the Chinese herb group, and Chinese herb plus glucocorticoid group were significantly lower than the level in the model group. The HPA expression levels correlated signifi- cantly with the proteinuria level. No significant dif- ference was found in the HPA level in urine be- tween the intervention groups and the model group, whereas the model group had a higher uri- nary HPA level than the control group. Nephrin mRNA expression levels in the model group were higher than those in the control group. Nephrin mRNA expression levels were significantly lower in the intervention groups than that in the model group, especially the Chinese herb plus glucocorti- cold group. Compared with the control group, themodel group showed increased nephrin expression in the kidney. Nephrin levels in the other groups, es- pecially in the Chinese herb plus glucocorticoid group, were significantly lower than that in the model group. The nephrin levels in the kidney were negatively correlated with the proteinuria level. CONCLUSION： Yiqiyangyin recipe could attenuate foot process injury particularly in combination with a steroid reduce the development of proteinuria possibly by inhibition of HPA in the kidney, and reg- ulate the expression of nephrin in rats with ADR-in- duced nephropathy. Our study showed that treat- ment with Yiqiyangyin recipe plus glucocorticoid was better than a singular intervention, and we ex- plored the pharmacological mechanism of this combination by biochemical and molecular biologi- cal analysis to provide a basis for clinical applica- tion.

Long-Term Follow-Up of Chinese Herbal Medicines Combined with Conventional Treatment in Patients with Acute Coronary Syndrome after Percutaneous Coronary Intervention: A Multicenter Randomized Controlled Trial

Objective： To evaluate the prognosis effect of Chinese herbal medicines（CHMs） for benefiting qi and activating blood circulation adjunctive to conventional treatment in patients with acute coronary syndrome（ACS） after percutaneous coronary intervention（PCI）. Methods： A total of 702 patients with ACS who underwent PCI were enrolled and randomly assigned to receive conventional treatment plus CHMs for benefiting qi and activating blood circulation（treatment group, 351 cases） or conventional treatment alone（control group, 351 cases） for 6 months. Six months later, all patients received conventional treatment alone. Follow-ups were scheduled at 6th, 12 th, 18 th, 24 th month after enrollment in April 2008, and the final follow-up visit was during September 2011 and November 2011. The primary endpoint was the composite of cardiac death, nonfatal myocardial infarction or revascularization（PCI or coronary artery bypass grafting）; and the secondary endpoint was the composite of re-admission for ACS, congestive heart failure, nonfatal stroke or other thrombus events. Results： A total of 621（88.59%） patients completed 35.4±3.8 months follow-up, while 80（11.41%） patients withdrew from the trial（41 in the treatment group and 39 in the control group）. The incidence of primary endpoint was 5.7%（20 patients） in the treatment group versus 10.86%（38 patients） in the control group [relative risk（RR）： 0.53; 95% confidence interval（CI）： 0.30, 0.88; P=0.013; absolute risk reduction（ARR）： –0.052, 95% CI： –0.06, 0.01]. The incidence of secondary endpoint was 5.98%（21 patients） in the treatment group versus 10.28%（36 patients） in control group（RR： 0.58, 95% CI： 0.33, 0.97, P=0.037; ARR： –0.043, 95% CI： 0.06, 0.01）. Most of the primary and secondary endpoints were occurred in 18 months（84.50% in the treatment group versus 78.10% in the control group）. Conclusion： CHMs for benefiting qi and activating blood circulation adjunctive to conventional treatment improved clinical outcomes for patients with ACS after PCI in long-term follow-up.
