Ischemic heart disease (IHD), which has been considered to be exclusively caused by stenosis or occlusion of coronary artery, is a significant cause of morbidity and mortality worldwide. Mitochondrial dysfunction is the main pathological basis of ischemic heart disease and reperfusion injury, and moderate mitochondrial autophagy can selectively remove damage proteins and organelles to maintain intracellular homeostasis, so mitochondrial autophagy is important for maintaining the homeostasis of cardiomyocytes. Natural drugs from plants are widely used in ischemic heart disease. In recent years, more and more natural drugs have been proven to alleviate myocardial cell damage after ischemia/reperfusion through mitochondrial autophagy. This paper reviews the research progress of natural drugs from plants medicines regulating mitochondrial autophagy in the treatment of ischemia heart disease.

Salvianolic acids are the main water-soluble active compounds of Salvia miltiorrhiza and have been widely used for the treatment of cardiovascular diseases. Based on the latest studies in China and abroad, we summarize the pharmacological effects and mechanism of salvianolic acids on ischemic heart disease by describing how salvianolic acid A and salvianolic acid B protect the vascular endothelium, relax coronary arteries, promote angiogenesis and anti-platelet aggregation, inhibit the inflammatory response, anti-cell apoptosis, and scavenge free radicals. This review provides a theoretical basis for further research on the effects of salvianolic acids on ischemic heart disease and their potential for drug development.

In the treatment of hypertensive crisis, the novel Rho kinase inhibitor DL0805-2 can rapidly lower systematic blood pressure, reduce pulmonary artery pressure, and has a significant protective effect on lung injury. This experiment intends to evaluate the efficacy of DL0805-2 against pulmonary arterial hypertension (PAH) and preliminarily reveals its underlying mechanism. Animal welfare and experimental procedures are in accordance with the provision of the Animal Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Sciences. Sprague Dawley (SD) rats were randomly divided into DL0805-2 low, medium, and high dose groups (1, 3, and 10 mg·kg^-1), bosentan positive control group, model group, and blank control group. The drug was administered daily on the 7th day after model establishment by monocrotaline injection. On the 25th day of the experiment, relevant indicators were examined to observe the therapeutic effect of DL0805-2 on pulmonary hypertension. DL0805-2 significantly relieved the abnormal changes in the physiological parameters related to PAH induced by monocrotaline, including reducing right ventricular systolic pressure, alleviating cardiac damage caused by pressure overload, and reducing the levels of endothelin-1 and inflammatory factors in lung tissues. DL0805-2 also attenuated pulmonary arteries remodeling. It was preliminarily discovered that DL0805-2 exerts preventive and therapeutic effect on PAH through Rho-kinase pathway. Our results suggested that DL0805-2 had good therapeutic effects on monocrotaline-induced PAH rat model. It intervened early in the disease process, effectively prevented the development of the disease, and reduced the mortality of the diseased animals. The mechanism is related to Rho-kinase pathway.

Epigenetics comprises the modifications made in gene expressions without changing the DNA sequence itself. Significant epigenetic changes take place during spermatogenesis and fertilization and exert direct influences on embryogenesis. This article provides an overview of the latest researches on epigenetics of male germ cells and a brief discussion on the correlation of sperm with embryogenesis in four aspects: DNA methylation, histone modification, regulation of non-coding RNAs, and genomic imprinting.

OBJECTIVETo study the clinical efficacy of the laparoscopic surgery in combination of Quyu Jiedu Recipe (QYJDR) on endometriosis (EMs)-related infertility patients.

METHODS130 EMs-related infertility patients of blood stasis and toxin accumulation syndrome diagnosed and treated by laparoscopic surgery were randomly assigned to two groups, i.e., the test group (75 cases) and the control group (55 cases). All patients received routine progesterone treatment after laparoscopic surgery. QYJDR was given to patients in the test group after laparoscopic surgery, lasting for twelve months. The pregnancy rate within one year after laparoscopic surgery were compared between the two groups. The Chinese medicine syndrome integrals, serum endometrium antibody (EMAb) and cancer antigen 125 (CA125) levels were compared between before drug therapy and three months after drug therapy.

RESULTSThe pregnancy rate within one year after laparoscopic surgery was higher in the test group than in the control group [61.33% (46/75) vs 45.45% (25/55)], showing significant difference (P<0.05). The Chinese medicine syndrome integral was (16.07 +/- 6.77) score and (7.25 +/- 3.27) score before and 3 months after drug therapy in the test group, while it was (15.92 +/- 7.51) score and (12.73 +/- 6.12) score in the control group. The Chinese medicine syndrome integral after drug therapy was lower than that before drug therapy in the same group. Besides, the integral difference between before and after drug therapy was higher in the test group than in the control group [(9.12 +/- 6.16) score vs (3.48 +/- 2.06) score)], showing statistical difference (P<0.05). After three-month drug therapy, the serum EMAb negative conversion rate was obviously higher in the test group than in the control group (44.44% vs 15.62%), showing statistical difference (P<0.05). The serum CA125 level was (31.88 +/- 15.78) U/mL before drug therapy and (18.82 +/- 10.08) U/mL three months after drug therapy in the test group, while it was (30.63 +/- 19.28) U/mL and (18.05 +/- 11.20) U/mL respectively in the control group. It was lowered after drug therapy in the two groups with statistical difference (P<0.05). There was no statistical difference between the two groups after drug therapy (P>0.05).

CONCLUSIONSThe laparoscopic surgery in combination of QYJDR could effectively improve clinical symptoms of EMs patients of blood stasis and toxin accumulation syndrome, promote negative conversion of EMAb, lower serum CA125 levels, and elevate the clinical pregnancy rate. QYJDR is an effective formula in treatment of EMs-related infertility.
