RESUMEN
Microbiome is a novel research field related to human health,agriculture,bio-energy and the environment. Gut microbiome has received much attention from researchers recently. Studies have shown that gut flora is related to some diseases,such as digestive disease(inflammatory bowel disease),metabolic disease(type 2 diabetes), cardie-cerebral vascular disease(Parkinson disease). Traditional Chinese materia medica(TCMM) has long been used as a tonic and taken in a large amount. Gut flora has an effect on pharmacology and toxicology of TCMM after entering the gastroin?testinal tract. This article is intended to review recent researches on microbiome,common detection techniques and the relationship with hepatotoxicity induced by Polygonum multiflorum Thunb.,scutel?laria baicalensis that directly affects the intestinal tract,nephrotoxicity induced by Rhizoma Alismatis and pneumonia induced by Xiao-Chaihu-Tang.

RESUMEN
Epigenetic is a hotspot of post-genomic era research, and epigenetic modification is a mechanism in the study of cardiovascular disease. Myocardial ischemia-reperfusion injury (MIRI) is one of the problems in the cardiovascular disease, and many experimental interventions are reported in the protection of the ischemic myocardium in experimental animals. However, with the exception of early reperfusion, none has been translated into clinical practice. There is an advantage of traditional Chinese medicine (TCM) in the regulation of epigenetic modification, and pathogenesis of myocardial ischemia-reperfusion injury. This review article is prepared to cover the research progress in the treatment of myocardial ischemia-reperfusion injury by TCM with a focus on epigenetic regulation. The epigenetic regulation is documented in TCM theory through a systematic review of the protecting drugs in the MIRI development guidelines.
RESUMEN
Reperfusion is the most effective treatment for acute myocardial infarction, markedly reducing mortality and morbidity. Reperfusion however induces necrotic and apoptotic damages to cardiomyocytes, that were viable prior to reperfusion, a process called myocardial ischemia/reperfusion injury(MI/RI). Over the past 30 years, hundreds of experimental interventions (both pharmacologic and nonpharmacologic) have been reported to protect the ischemic myocardium in experimental animals; however, with the exception of early reperfusion, none has been translated into clinical practice. The population-based survey assessed men have about twice the total incidence of morbidity and mortality of women, and the sex gap in morbidity tends to diminish after age 45 years. So hormone replacement therapy (HRT) is given to treat the MI/RI, and lots of studies shows that the side effect is greater for estrogen, compared with phyestrogen. In this article, we review the important pathogenesis of myocardial ischemia reperfusion injury, the prevention and limitations of HRT. And we highlight the mechanism of phyestrogens treatment the MI/RI in experiment. The aim is to provide the theoretically new way of develop the safe and effective products for the researchers.

BACKGROUND: In recent years, epidemiological studies have found that the saturation of transferring or the increased level of serum ferritin are associated with the attacks of cancer, coronary heart disease, diabetes mellitus, Parkinson disease, liver disease and the diseases of immune system. Therefore, it is suggested that the intake of excessive iron may cause adverse influence on the healthy of human body.OBJECTIVE: To establish high-iron model in mice by using full-rate diet pellets by adding regular quantitative intraperitoneal injection of iron dextran, and observe the iron levels in vivo and the changes of organ coefficients.DESIGN: A comparative observation.SETTING: Department of Nutrition and Food Hygiene, School of Public Health and Tropic Medicine, Southern Medical University.MATERIALS: The experiment was carried out in the laboratory of the Department of Nutrition and Food Hygiene, School of Public Health and Tropic Medicine, Southern Medical University in May 2006. Forty Kunming mice of SPF grade, 20 males and 20 females, weighing 18-22 g, were provided by the Animal Experimental Center of Southern Medical University. The mice were randomly divided into control group (n =10) and high-iron model group (n =30) by introperitoneal injection of saline and iron dextran respectively, and the latter group was subdivided into low, middle and high-dosage groups (6.25, 12.5 and 25 g/L) respectively, 10 mice in each group. Full-rate diet pellets (iron content was 370 mg/kg)were purchased from the Animal Experimental Center of Southern Medical University. Iron dextran reagent (norm: 2 mL containing 50 mg iron) was the product of Zhejiang Ruian Pharmaceutical Factory (certification number: H33021758).The kits of superoxide dismutase (SOD) and maldondialdehyde (MDA) were provided by the Nanjing Jiancheng Bioengineering Institute.METHODS: Mice in each group were raised in plastic stainless steel cages respectively at (23±3) ℃, and they were free to the access of food and deionized water. Mice in the low, middle and high-dosage group were treated with intraperitoneal injection of iron dextran once every other day, 0.8 mL for each time, whereas iron dextran was replaced by saline in the control group, all the mice were treated for 6 weeks, and their nutritionol conditions were observed. All the mice were killed at the end of the 6th week. The iron contents in organs of heart, liver, spleen, lung and kidney, and serum were determined with atomic absorption spectrophotometer and automatic biochemical analyzer respectively; Pathohistological examination of organs were performed; The organ coefficients of liver and spleen were calculated; MDA content and SOD activity in serum were determined.MAIN OUTCOME MEASURES: General conditions of mice in each group; Iron contents in organs and iron concentration in serum; Organ coefficients of liver and spleen; MDA content and SOD activity in serum; Pathological changes.RESULTS: In the high-iron model group, the body figures of the mice were changed, body masses were obviously decreased. The iron contents in organs and serum of mice in the high-iron model group were all obviously increased as compared with those in the control group (t =5.841, P < 0.01), the organ coefficients of liver and spleen were also markedly increased (t =5.841, P < 0.01), which were all in a dosage-dependent manner. The MDA content in serum was obviously increased (t =5.841, P < 0.01) whereas the SOD activity was obviously decreased (t =12.924, P < 0.01) as compared with those in the control group. The pathohistological examination under light microscope showed that there were pathological damages of different degree occurred in the tissue and cells and cell degeneration was observed,which affected the normal physiological function of cells.CONCLUSION: High-iron mice models can be successfully established by the intraperitoneal injection of iron dextran.The storage of excessive iron in vivo will result in the organic damages.
