Objective To observe the effect of Ganshu Granule on different models of fatty liver in rats. Methods Rats with acute fatty liver induced by alcohol and carbon tetrachloride, rats with chronic fatty liver induced by alcohol and high-fat diet, and rats with acute fatty liver induced by ethionine were used, and the effects of different doses of Ganshu Granule on serum lipid metabolism, intrahepatic lipid metabolism and histopathological changes in liver were observed. Results In fatty liver rats induced by alcohol and carbon tetrachloride, Ganshu Granule could reduce the level of total cholesterol (TC), triglycerides (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in serum and could decrease total fat and glycogen(Gn) in liver obviously. In fatty liver rats induced by alcohol and high-fat diet, Ganshu Granule could significantly decrease the level of TC, TG, ALP, LDL and ALT in serum and could reduce the content of total fat, TG and Gn in liver obviously. In fatty liver rats induced by ethionine, Ganshu Granule could decrease the level of TC, TG and ALT in serum, raise the level of HDL in serum and could decrease the content of total fat, TG and Gn in liver obviously. The histopathologic results showed the degree of hepatic steatosis and hepatocellular necrosis were lessened in all of the treated groups. Conclusion Ganshu Granule is effective in preventing and treating fatty liver.

The validity and reasonableness of emotional data are the key issues in the cognitive affective computing research. Effects of the emotion recognition are decided by the quality of selected data directly. Therefore, it is an important part of affective computing research to build affective computing database with good performance, so that it is the hot spot of research in this field. In this paper, the performance of two classical cognitive affective computing databases, the Massachusetts Institute of Technology (MIT) cognitive affective computing database and Germany Augsburg University emotion recognition database were compared, their data structure and data types were compared respectively, and emotional recognition effect based on the data were studied comparatively. The results indicated that the analysis based on the physical parameters could get the effective emotional recognition, and would be a feasible method of pressure emotional evaluation. Because of the lack of stress emotional evaluation data based on the physiological parameters domestically, there is not a public stress emotional database. We hereby built a dataset for the stress evaluation towards the high stress group in colleges, candidates of postgraduates of Ph. D and master as the subjects. We then acquired their physiological parameters, and performed the pressure analysis based on this database. The results indicated that this dataset had a certain reference value for the stress evaluation, and we hope this research can provide a reference and support for emotion evaluation and analysis.

Objective To evaluate t le effects of various mutants of PAK6 kinase on the proliferation of prostate cancer cells and their roles in the pathology of prostate cancer. Methods Variant mutants of PAK6 kinase, including wild type ( WT),kinase activated type (SN) and kinase inactivated type (KM) , were in vitro constructed according to the PAK6 sequence,and were transfected into the LNCaP cells by Lipo-fectamine. G418 was used to select the stable cell line. Phosphorylated PAK6 antibody was used in Western blot to detect the kinase expression in the eel.s. The proliferation rate was measured by MTT assay;the growth effects of the cells stimulated by androgen were also recorded and compared. Results Different LNCaP cell lines expressing wild type, kinase activated and kinase inactivated PAK6 were prepared successfully. Wild type (WT) PAK6 and the kinase activated PAK6-SN significantly inhibited the growth of LNCaP cells by 32. 1% and 39. 3%,respectively (P

Objective To quantify the expression levels of calpain 1 and caspase-3 in lichen planus (LP) lesions and their relationship with the apoptosis in keratinocytes.Methods Biopsy samples were obtained from the lesions of 20 patients with LP and normal skin of 10 healthy controls,and embedded in paraffin.Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) was used to evaluate the apoptosis in keratinocytes,and immunohistochemical staining to detect the expressions of calpain 1 and caspase-3,in these tissue specimens.Data were processed by SPSS 13.0 software.Comparison analysis was carried out by t test for apoptosis index,and by rank sum test for the expressions of calpain 1 and caspase-3.Spearman correlation analysis was conducted to evaluate the relationship between these parameters.Results The apoptosis index of keratinocytes was higher in LP lesions than in the normal skin (67.59 ± 13.50 vs.28.26 ± 7.56,t =8.52,P ＜ 0.01).Significantly increased expressions of calpain 1 and caspase-3 were observed in the epidermis of LP lesions compared with the normal skin (T =78.00 and 77.00,respectively,both P ＜ 0.01).The expressions of both calpain 1 and caspase-3 were positively correlated with apoptosis index of keratinocytes (r =0.71 and 0.74,respectively,both P ＜ 0.01).Conclusions The expressions of calpain 1 and caspase-3 are upregulated in LP lesions,which may be closely associated with the accelerated apoptosis in keratinocytes.

Objective To investigate the effects of mechanical stretch on the pelvic floor dysfunction and study the regulation of mechanical stretch on the morphology and extracellular matrix mRNA expression of fibroblasts derived from human uterosacral ligament.Methods 13 patients who underwent hysterectomy surgery due to uterine benign diseases in the Obstetric and Gynecological Department of the Second Hospital of Hebei Medical University from October 2009 to September 2010 and had no pelvic organ prolapse were recruited in this study.Fibroblasts of uterosacral ligament were cultured by collagenase digestion and identified by morphology and immunocytochemical methods.Fibroblasts of 3 ～ 4 generations were stretched by flexcell-4000 tension system for 0,4,15,24 hours.Total RNA was extracted from the fibroblasts and mRNA of Collagen Ⅰ,Collagen Ⅲ,matrix metalloproteinase-1 and tissue inhibitor of metalloprot einase-1were measured with real-time fluorescence quantitative PCR.Results In response to mechanical stretch,the morphology and orientation of the uterosacral ligament fibroblasts were changed as well as their synthetic function.Collagen Ⅰ mRNA for 4 or 15 hours' stretch (0.777 ± 0.251,0.730 ± 0.248)were statistically down regulated compared with 0 hour ( 1.000 ±0.284),( q =4.5786,4.6458,p ＜0.05).But for 24 hours'stretch,the mRNA expression ( 1.102 ±0.308) of collagen Ⅰ restored to the level of 0 hours.The expressions of collagen Ⅲ mRNA for 4,15,24 hours' stretch (4.771 ± 0.879,6.146 ± 1.109,5.022 ± 0.907 )were statistically up regulated compared with 0 hour (1.001 ± 0.284),(q =15.9481,21.7647,17.0099,P ＜ 0.01 ).MMP-1mRNA for 4,15,24 hours' stretch (6.420 ± 2.143,23.695 ± 2.221,20.169 ±2.794) were statistically up regulated compared with 0 hour ( 1.000 ±0.414),( q =9.3421,39.1178,33.0403,P ＜ 0.01 ).TIMP-1 mRNA for 4,15 hours' stretch (0.455 ± 0.370,0.481 ± 0.386)were statistically down regulated compared with 0 hour( 1.000 ± 0.425 ),( q =6.5265,6.3106,P ＜0.05).But for 24 hours'stretch,the mRNA expression( 0.883 ± 0.538 ) restored to the level of 0 hours.Conclusions The morphology,orientation and the synthesis function of the uterosacral ligament fibroblasts can be regulated by mechanical stress.Extracellular matrix remodeling may be adaptive changes due to the mechanical stress.

Aim To study the relationship between the vasodilatation effects of daidzein and M-receptor in the endothelial cell, extracellular Ca2+ and intracellular Ca2+.Methods Measurement of isometric force of rabbit thoracic aortae rings was performed. Results Dai(3～100 ?mol?L-1 ) significantly inhibited the contractive response of phenyleohrine dependent on intracellular Ca2+ release and extracellular Ca2+ inflow;a shift was produced to the right of the concentration-effect curve of KCl and the maximum response was depressed by Dai(10～100 ?mol?L~ -1 ); Dai(10,30,100 ?mol?L-1 ) enhanced the relaxing effect induced by acetylcholine in a concentration-dependent manner,but the relaxing effect was inhibited after using atropine to block the M-receptor. Conclusion The relaxing effect of Dai was related to the inhibition of the receptor-mediated Ca2+ -influx and Ca2+-release;Dai induced direct relaxing effect by activating the M-receptor in the endothelium and releasing EDRF, which was similar to ACh, and this effect was endothelium-dependent.

Objective To investigate the effects of estrogen on mismatch repiar gene expression in colonic mucosa in vivo. Methods A total of 42 healthy individuals underwent colonoscopy were enrolled in the study. Half an hour before colonoscopy examination, blood sample was taken for determining the serum estradiol (E2) level. N ormal colonic mucosal tissues determined by naked eye under colonoscopy examination were taken in the right hemi colon to detect HMLH1 and hMSH2 gene expression by semi-quantitative RT-PCR and immunohistochemistry staining. Then the correlation of serum E2 levels with hMLH1 and hMSH2 expression in colonic mucosa was analyzed. Results A bimodal curve was presented for the correlation between serum E2 level in healthy individuals and hMLH1 expression in colonic mucosa. A strong positive correlation of E2 level with hMLH1 expression in normal colonic mucosa was observed when serum E2 level was more than 45 pg/ml (For mRNA, P=0. 003, r=0. 701; for immunohistochemistry positivity index, P=0. 000, r=0. 874).However there was no correlation between E2 level and hMSH2 expression. Conclusion High serum E2 level might increase the hMLH1 gene expression in colonic mucosa in vivo.
