AIM To explore the effects of Sini Decoction (Aconiti lateralis Radix Praeparata,Zingiberis Rhizoma,Glycyrrhizae Radix et Rhizoma) on rat myocardial fibrosis induced by isoproterenol.METHODS Forty SD rats were randomly divided into blank,model,captopril [100 mg/(kg · d)] and Sini Decoction [3.8 g/(kg · d)] groups,with ten rats in each group.Except for the blank group,the rest rats were given subcutaneous injection of isoproterenol [5 rg/(kg · d)] to prepare myocardial fibrosis model,and successive administration lasted for four weeks.At 20 h after the last administration,hemodynamics changes of heart were detected;heart weight indexes were calculated;the changes of myocardial pathological morphology were observed by HE and Masson staining;NO level in serum was measured by nitrale reduetase;SOD activity in serum was measured by xanthinoxidase method;MDA level in serum was measured by thiobarbituric acid method;the protein expressions of RhoA,ROCK1 and eNOS in myocardial tissue were detected by Western blot method.RESULTS Compared with the model group,the cardiac function of rats was significantly improved;the myocardial collagen content was significantly decreased;the MDA level in serum was obviously decreased;the NO level and SOD activity were significantly increased;the protein expressions of RhoA and ROCK1 in myocardium tissue were significantly reduced,and the protein expression of eNOS was markedly increased in the Sini Decoction group.CONCLUSION Sini Decoction can improve the isoproterenol-induced myocardial fibrosis in rats,and its mechanism may be related to inhibiting the RhoA/ ROCK signaling pathway,in turn,raising the expression of eNOS,which leads to reduced oxidative stress.

Objective To investigate the relationship among the proliferation of CD4+T cells, the intracellular levels of interleukin-10 (IL-10) and transforming growth factor-?1(TGF-?1), and allergic bronchial asthma. Methods Dermatophagoides farinae antigen were prepared as allergen. Twenty-five patients with asthma and 15 healthy individuals were enrolled and divided into blank control group, allergen group and self control group, respectively, after venous blood sample collection. The proliferation of CD4+T cells and the distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 were measuredby flow cytometry (FCM). Results The distributions of CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 could hardly be detected in the peripheral blood samples of the blank controls of the patients with asthma and healthy ones. In the allergen group of the healthy individuals, the peripheral blood CD4+T cells were significantly proliferated, and the proportions of CD4+T cells andCD4+/IL-10+ cells were much higher than the self control group, while there was no significantly increase in the proportions of CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 subgroups. In the allergen group of those with asthma, the proportions of peripheral blood CD4+, CD4+/IL-10+, CD4+/TGF-?+1 and CD4+/IL-10+/TGF-?+1 cells were not found significantly increased compared with those self controls. After being activated by allergen, the proportion of peripheral blood CD4+/IL-10+ cells was significantly lower in the patients with asthma than the healthy individuals(P

The development of female germ cell is the cornerstone for animal reproduction. Mammalian oocyte and early embryo have many distinct phenomena and mechanisms during their growth and development, involving series dynamic changes of protein synthesis/degradation and phosphorylation. Research on the regulatory mechanism of oocyte division, maturation, and developmental principle of pre-implantation embryo is an important topic in the field of animal developmental biology. Proteomics using all of proteins expressed by a cell or tissue as research object, systematically identify, quantify and study the function of all these proteins. With the rapid development of protein separation and identification technology, proteomics provide some new methods and the research contents on fields of oogenesis, differentiation, maturation and quality control, such as protein quantification, modification, location and interaction important information which other omics technology can not provide. These information will contribute to uncover the molecular mechanisms of mammalian oocyte maturation and embryonic development. And it is great significant for improving the culture system of oocyte in vitro maturation, the efficiency of embryo production in vitro, somatic cell clone and transgenic animal production.
