Objective To study the effect of atorvastatin on the levels of high sensitive C-reactive protein (hs-CRP)in coronary heart disease(CHD)patients with different Gensini score.Methods 120 cases of CHD from March 201 1 to September 2015 in our hospital were selected as the research subjects.According to the different Gensini scores,they were divided into group A (Gensini score <40 ),group B (Gensini score 40 -60 ),group C (Gensini score 60 -80 ),group D (Gensini score >80 ),with 30 patients in each group.All patients were given atorvastatin treatment,the therapeutic effect of the four groups,the total cholesterol(TC),three glycerol(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL -C)and hs -CRP levels after treatment were compared.Results After treatment,the lower the Gensini score,the better curative effect,four groups had statistically significant difference in the therapeutic effects(P<0.05),and the total effective rates of group A,B, C and D were 96.7%,86.7%,76.6%,56.7%.After treatment,the TG,TC,HDL-C,LDL-C in four groups were improved,A group improved significantly better than the B group,B group improved better than those of C group,C group improved better than those of D group,the differences were statistically significant(F=6.253,6.258,5.856, 6.259,all P<0.05).After treatment,the levels of hs-CRP in group A,B,C and D were (8.2 ±3.9)mg/L,(11.9 ± 6.9)mg/L,(19.2 ±9.3)mg/L,(24.5 ±11.6)mg/L,the hs-CRP levels of four groups were lower,hs-CRP level after treatment in group A was lower than that of B,C,D groups;and hs-CRP level after treatment in group B was lower than that of group C,D;hs-CRP level of C group after treatment was lower than that of group D.The differ-ences were statistically significant(t=12.651,9.185,4.982,3.030,all P<0.05).Conclusion The level of serum hs-CRP in patients with CHD is higher,and the level of hs-CRP is positively correlated with the Gensini score.

OBJECTIVETo study the effect of nadroparin in the migration of breast cancer cells MDA-MB-231 and its action mechanism.

METHODThe MTT test was adopted to observe the effect of different concentrations of naringenin on the growth capacity of breast cancer cells MDA-MB-231. Wound healing and transwell experiment analysis were conducted to detect the effect of naringenin on the migration of breast cancer cells MDA-MB-231. Western blotting was adopted to investigate the effect of naringenin on protein expressions of MDA-MB-231 cell Integrin β3, β1 and matrix metalloproteinase MMP-2 and MMP-9. The computer virtual docking technique was used to evaluate the combining capacity of naringenin and Integrin β3 in vitro.

RESULTNaringenin inhibited the migration of MDA-MB-231 cells in a dose-dependent manner. In wound healing and transwell experiments, with the increase in the concentration of naringenin, the number of migrant MDA-MB-231 cells and the invasion capacity of breast cancer cells decreased. Naringenin could inhibit the protein expression of Integrin β3 in a dose-dependent manner, but with unobvious effect on expression of Integrin β1. Besides, naringenin could significantly inhibit the protein expressions of MMP-2 and MMP-9. The results of the computer virtual docking showed a negative value in the combining capacity between naringenin and Integrin β3, indicating the high affinity between them.

CONCLUSIONNaringenin can inhibit the growth capacity of breast cancer cells MDA-MB-231 and block the migration and invasion of breast cancer cells MDA-MB-231. Its mechanism is to down-regulate MMP-2 and MMP-9 expressions after combining with Integrin β3.

The Wnt/β-catenin signal transduction pathway is essential for regulating cell proliferation, movement, differentiation and embryo development. Researchers have found that Wnt pathway is an important regulation factor in the early stimulation of the cardiogenesis and contacts closely the several key events during cardiac morphogenesis. The article reviews the recent studies about the relation between cardiac development and Wnt pathway in early embryo.

Objective To study the effect of dehydroepiandrosterone (DHEA) on the immune system by measuring the apoptosis and expression of Fas/FasL mRNA of thymocytes. Methods The cell viability of thymocytes was determined by MTT assay. Thymocyte apoptosis was detected by agrese gel electrophoresis. The expression of Fas and Fas-L was analyzed by a semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) method. Results DHEA decreased the cell viability of thymocytes and induced thymocytes apoptosis and increased the levels of mRNA of Fas/FasL. Conclusion DHEA can induce apoptosis of thymocytes through Fas/Fas-L pathway. It suggests that DHEA may play a role in certain autoimmune diseases related to apoptosis disturbance.
