Aim To investigate the effect of atorvastatin on AngⅡ-induced hypertrophic myocytes in vitro.Methods Hypertrophy in neonatal rat cardiac myocytes(MC) was established via culture with angiotensin Ⅱ(AngⅡ),then the effect of atorvastatin on the hypertrophy was detected.The surface area of MC was analyzed with the aid of NIH Image J software,and the synthetic rate of protein in MC was detected with()~3H-leucine incorporation.mRNA expression of atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP) and Corin was measured using reverse transcription-polymerase chain reaction(RT-PCR).Results The surface area,()~3H-leucine incorporation and mRNA expression of ANP,BNP and Corin in hypertrophic myocytes were decreased after treatment of atorvastatin in a dose-dependent manner,but no change was found in the myocytes treated with DMSO.Conclusion Atorvastatin inhibits cardiac hypertrophy in vitro and the role might be independent of the cholesterol lowering effect of atorvastatin.

Twenty-seven ERF transcription factor family genes were isolated from Arnebia euchroma, with an average size of 1,010 bp, each gene encoded a 212 amino acids on average. The gene structure and expression of physicochemical properties, subcellular localization, signal peptides, senior structural domains and conservative forecasting, and analysis of A. euchroma were studied comparing with ERF gene gi261363612 of Lithospermum erythrorhizon, and phylogenetic analysis of A. euchroma ERF family was carried out. The results showed the existence of three conserved domains in this family, the senior structure based on random coil and it clustered into CBF/DREB and ERF subfamilies.

To investigate the therapeutic effect of artesunate on mouse cytomegalovirus pneumonia, the BALB/c-nu mice were infected with murine cytomegalovirus-green fluorescent protein (MCMV-GFP) by nose dropping method. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Guangzhou Medical University. The BALB/c-nu mice were randomly divided into five groups: control group, MCMV pneumonia group, and artesunate (60, 120, and 240 mg·kg^-1) groups. The survival rate, weights, and virus loads in lungs among the groups were observed. The degree of histopathologic changes in lungs was assessed directly by hematoxylin-eosin (HE) assay. MCMV-GFP expression was assessed by immunofluorescence. In addition, reverse transcription polymerase chain reaction (RT-PCR) analysis was performed to investigate the content of major immediate early 1 (Mie1) mRNA, and enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of inflammatory factors, interleukin 10 (IL-10), IL-6, and tumor necrosis factor-α (TNF-α). Western blot analysis was used to detect the expression of the changes of nuclear factor-kappa B (NF-κB) signaling pathways in total proteins. Compared with MCMV group, artesunate (120 mg·kg^-1) significantly increased body weights of MCMV-infected nude mice over 30 days, and decreased the viral titer in lung homogenate, lung inflammation, and histological severity. Moreover, the administration of artesunate (120 mg·kg^-1) could downregulate the expression of phospho-NF-κB (p-NF-κB) p65 in the lungs of mice. The present study suggested that artesunate can protect the immunocompromised mice from MCMV-induced interstitial pneumonia via downregulating NF-κB signaling pathway, thus attenuating inflammation in the lungs.

AIM:Cinnamyl aldehyde (CA) is one alcohol ingredient derived from Cinnamomum cassia,which is widely used in treating chronic skin wound in Chinese medicine with the curative effect of ‘rescuing YANG’. The purpose of the present study was to investigate the expression of c-Fos, c-Myc proteins at different time points in NIH3T3 treated with CA and explore the possible mechanism of promoting cell proliferation by CA. METHODS: MTT assay was used for observing cell proliferation. Expression of c-Fos and c-Myc proteins in NIH3T3 cells were assessed by immunocytochemistry assay. RESULTS: The cell proliferation was promoted obviously when CA concentration was between 8.8?10-2 ?g/L and 8.8?10 ?g/L. CA at concentration of 5.5 ?g/L significantly induced expression of c-Fos, c-Myc proteins at 2-3 h after the stimulation compared with control group (P

AIM: To observe the effects of six common traditional Chinese herbs of activating blood, paeoniae rubra radix, salviae miltiorrhizae radix, ligustici, rhizome, notoginseng radix, pruni persicae semen and wine staemed radix et rhizome, on atherosclerotic plaque structure and stabilization in ApoE gene-deficient mice. METHODS: Four sections of the aortic root were choosen and stained with hematoxylin and masson. All sections were measured with Image-ProDR○ Plus Version 4.5.1 (IPP) software. RESULTS: Compared with the model group, plaque area corrected by cross-sectional vessel wall area reduced significantly in salviae miltirrhizae radix treatment group, lipid core area reduced in paeoniae rubra radix group, pruni persicae semen and wine steamed radix et rhizome treatment group, minimum thickness of fibrous cap became thicker significantly in salviae miltiorrhizae radix, ligustici, rhizome, pruni persicae semen and wine steamed radix et rhizome treatment group. CONCLUSION: These Chinese herbs may stabilize the atherosclerotic plaques in ApoE gene-deficient mice by interfering their structure, but their effects do not parallel with their activating blood efficacy in traditional Chinese medicine.

AIM: To study the effects of Yangyu Tuji (YYTJ) on delayed healing wound of diabetic rats caused by streptozotocin (STZ). METHODS: SD male rats were randomly divided into control group (control), model group (model); and 3 different dose groups of YYTJ. 55 mg/kg STZ were given by intraperitoneal injection except for control group. After 30 days, a round skin of 1.6 cm diametre was excised on all dorsal back of rats. The healing time and healing rate were observed according to re-epithelization. The content of collagenⅠ and Ⅲ was observed by Picric acid-Sirius red staining , Matrix metalloproteinase-1, 13 (MMP-1, -13), tissue inhibitor of metalloproteinases-1 (TIMP-1) by immuno-histochemistry assay. All data were analyzed by IPP software. RESULTS: The healing time in each group treated with YYTJ was shorter than that in model group (P
