Objective To investigate the effect of HIF-2a silencing by transfection of siRNA into MG-63 cells un-der hypoxia. Methods HIF-2αexpression level in MG-63 cells under hypoxia was determined by Western Blot. Small in-terfering RNA (siRNA) was used to construct MG-63/siHIF-2α(siHIF-2α)cells and control MG-63/scramble (NC) cells. The expression levels of HIF-2α, Vascular endothelial growth factor (VEGF), p-Erk/ErK and Mcl-1 in MG-63, NC and si-HIF-2αcells was determined by Western Blot. NC and siHIF-2αcells were cultured under hypoxia. Cell viability was as-sessed by MTT assay. Migration was identified by scratch migration assay. Tumor formation was identified by clone formation assay. Nude mouse subcutaneous xenograft model was used to investigate tumor development in vivo. Results Hypoxia im-proved HIF-2αexpression in MG-63 cells in a time-dependent manner (F=2 037.412,P<0.001). HIF-2αexpression un-der hypoxia in siHIF-2αcells was lower than that in NC cells (P<0.01). Cell viability of siHIF-2αcells under hypoxia for 12 h and 24 h were lower than that in NC cells (P<0.05 or P<0.01). The relative width of scratch in siHIF-2αgroup under hypoxia for 12 h and 24 h were larger than that in NC group (P<0.01 or P<0.01). When cell counts reach 1 000-5 000, the clone formation rates of siHIF-2αcells were lower than that in NC cells (P<0.05 or P<0.01). The expression of VEGF, p-Erk/Erk and Mcl-1 protein under hypoxia in siHIF-2αcells was lower than that in NC cells(P<0.01). Tumor sizes, weights and density of siHIF-2α group in nude mice were suppressed compared with those in NC group (P<0.01). Conclusion Blocking HIF-2αsignal pathway warrants its investigation as a potential strategy in osteosarcoma treatment.

This study was aimed to observe the effect ofJia-Shen prescription (JSP) on angiotensinⅡ (AngⅡ) inhibition, ventricular remodeling in myocardial infarction (MI) rat model. The anterior descending coronary artery of Sprague-Dawley rat was ligated to establish the MI rat model. Rats were randomly divided into the 3 g JSP group, 6 g JSP group, losartan group, model group, and the sham-operation group. Intragastric administration of medication was given 24 h after MI. In the 3 g and 6 g JSP group, JSP was given at the dose of 3 g·kg-1·day-1 and 6 g·kg-1day-1, respectively. Losartan was given at the dose of 10 mg·kg-1·day-1 in the losartan group. Same volume of distilled water was given to the sham-operation and model group. Four weeks later, the left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD), posterior wall thickness (PWT), left ventricular ejection fraction (LVEF), left ventricular fractional shorten (LVFS), left ventricular weight index (LVWI), the distribution and content of collagen, plasma brain natriuretic peptide (BNP) and the AngⅡ content in myocardial tissues homogenate were observed. The results showed that 4 weeks after MI, compared to the model group, 6 g PJP reduced myocardial infarct size, LVWI, LVEDD and LVESD, and enhanced LVEF and LVFS (P< 0.05). In ischemic regions, compared to the model group, JSP can obviously reduce the content of collagen (P < 0.05). This effect had dose-dependent relationship. Plasma BNP and AngⅡ content in myocardial tissues homogenate were also obviously lower than the model group (P< 0.05). It was concluded that JSP can improve the ventricular remodeling of MI rat model. Its action mechanism may be through the AngⅡ inhibition, in order to improve the early stage left ventricular morphological remodeling, myocardial fibrosis and cardiac contractile function.

Objective To evaluate the relationship between the risk of breast cancer and abortions among nulliparous women. Methods Searched the data of Cochrane Library and PubMed before June 2014 to identify potentially studies which involved the relationship between the risk of breast cancer and abortions among nulliparous women. Data was extracted by two independent authors from each study. STATA software was used for statistical analysis. Calculated the pooled RR and 95% CI as the assessment of the link between abortions and breast cancer in fixed effects models. Results 13 studies were included. The study showed the RR and 95%CI of the relationship between the risk of breast cancer and abortions was 0. 98[0. 89,1. 08],P>0. 05 in nulliparous women, and the number of abortions was not associated with the risk of breast cancer. The RR and 95%CI of the relationship between the risk of breast cancer and induced abortions or spontaneous abor-tions were 0. 96[0. 88,1. 04],1. 01[0. 88,1. 14], respectively. Conclusion There is no correlation between breast cancer and abortions a-mong the nulliparous women, and the risk of breast cancer would not increas as the number of abortions increase.

Objective To study the reversal effect of tetrandrine (TET) on the multidrug resistance of Hep-2/ADM cell line and the possible mechanisms. Methods MTT method was used for the detection of the inhibitory effect of different concentrations of TET on the multidrug resistance of Hep-2/ADM cell line for selection of the non-toxicity concentration. MTT reduction assay was used to investigate the drug interaction of TET and vincristine (VCR) on HNE-1 (200) cell line. The reversal index (RI), accumulation and excretion of drug, and the apoptosis of Hep-2/ADM cell line were detected by flow cytometry. Results No toxicity to Hep-2/ADM cell line was found when TET concentration was lower than 1.5 ?g/ml. After interaction with TET (1.0 ?g/ml and 1.5 ?g/ml), RIs of VCR on Hep-2/ADM were 1.72 and 2.00 folds, respectively. TET at the concentration of 1.5 ?g/ml could increase the drug excretion and accumulation and also the apoptotic rate of VCR-induced Hep-2/ADM cell line. Conclusion TET can reverse the multidrug resistance of Hep-2/ADM cell line. The reversal effect may be related to the concentrations of TET. The possible mechanism may be that TET can increase the cell apoptosis of VCR-induced Hep-2/ADM cell line and can also increase the drug excretion and accumulation of the multidrug resistance cell line.

BACKGROUND: Leucine-rich repeats and immunoglobulin-like domains 1 (LRIG1) gene showed low expression in glioma cells. LRIG1 gene overexpression significantly enhanced LRIG1 mRNA and protein expression and inhibited its biological behavior. However, very few researchs are reported from the stand-point of inhibition of LRIG1 gene expression. OBJECTIVE: To construct specific RNA interference plasmids for LRIG1, establish stably transfected human glioma GL15 cell line, and observe its effect on expression of target gene LRIG1. METHODS: Designed and synthesized two shRNAs (named LRIG1-shRNA1 and LRIG1-shRNA2) specific for LRIG1 mRNA according to the GenBank, and one scrambled shRNA sequence as negative control, named pGenesil2-negative shRNA. The shRNA was inserted into pGenesil2 vector and sequenced. The recombinant vectors were transformed into E. coli. Picked up the positive clones and extracted the plasmids, which were transfected into GL15 cells by Metafectine. G418 was applied to select the stably transfected cell clones. Western Blotting was performed to examine the LRIG1 protein level.RESULTS AND CONCLUSION: The recombinant plasmids which contain shRNA were analyzed by restriction endonuclease digestion and DNA sequence, and it was proved that the fragment was inserted into the expected sites. Compared with the negative control group, the level of LRIG1 protein expression in pGenesil2-LRIG1-shRNA1(LRIG11) transfected cells and in pGenesil2-LRIG1-shRNA2(LRIG12) transfected cells was decreased by 47.9% (P < 0.01) and 32.8% (P > 0.05). The results confirmed that RNAi expressing vector specific for LRIG1 gene (pGenesil2-LRIG1-shRNA1) was successfully constructed, and the stable cell clones transfected with the shRNA expression vector showed inhibition of the expression of LRIG1 in glioma cell line GL15.

Objective To investigate the relationship between body mass index (BMI) and coronary artery calcification in order to provide theoretical and clinical basis for the prevention and treatment of coronary artery calcification.Methods Ninety hundred and eighty-three cases were selected as our subjects who were hospitalized in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine from Jan.2010 to Jul.2010 and undergone dual source CT coronary angiography.Of them,419 cases were male(male group),and 564 female (female group).The general information,clinical and biochemical indexes and coronary CTA results were collected.The patients were divided according to the BML Multivariate logistic regression analysis was applied to analyzed the relationship between BMI and coronary artery calcification,and multiple linear regression analysis was applied to analyzed the relationship between coronary artery calcification and BMI.Results There were significant differences between male group and female group in terms of age,height,body mass,BMI,smoking history,glomerular filtration rate (eGFR),triglyceride (TG),high density lipoprotein (HDL-C),left ventricular ejection fraction (LVEF),serum calcium,with peripheral vascular disease,as well as the baseline drugs,angiotensin converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB),calcium antagonists (CCB),statins compared the differences were statistically significant (P ＜ 0.05).The rate of slight coronary artery calcification in male group and female groups were not statistically significant(x2 =0.714,P =0.398),while the rate of no calcification,severe calcification were statistically significant (P ＜ 0.05).Multivariate Logistic regression analysis showed that high BMI(regression coefficient was-1.670,OR =0.967,95％ CI =0.953 ～ 0.980,P =0.005),age (regression coefficient was 1.422,OR =4.416,95％ CI:1.015 ～ 16.927,P =0.001),history of hypertension (regression coefficient was 0.128,OR =1.521,95％ CI:1.262 ～ 1.830,P =0.002),history of diabetes mellitus (regression coefficient was 0.364,OR =1.439,95 ％ CI:1.098 ～ 1.885,P =0.008),eGFR (regression coefficient was-0.5420,OR =0.004,95％ CI:0.001-0.019,P =0.014),LVEF (regression coefficient was-1.153,OR =0.316,95％ CI:0.127-0.787,P =0.002) and statins(regression coefficient was-6.745,OR:0.323,95％ CI:0.138-0.754,P =0.032) were correlated with coronary artery calcification.Multiple stepwise linear regression analysis showed that only eGFR(r =0.79,95％ CI:0.69-0.92,P =0.001) was in the equation.Conclusion High BMI is a protective factor for severe coronary artery calcification,but there is on linear correlation between BMI and moderate to severe coronary artery calcification score in patients.

Objective To identify the metabolic levels in prefrontal lobe in patients with post-concussion syndrome by proton magnetic resonance spectroscopy (1H-MRS), and to explore the relationship between metabolic levels and executive function. Methods The study was conducted in 40 patients with post-concussion syndrome and 20 normal controls. 1H-MRS on prefrontal lobe was performed in patients and controls, the NAA, Cho and Cr were measured and the ratios of NAA/Cr, Cho/Cr and NAA/(Cho + Cr) were determined. They were also evaluated executive functions by verbal fluency test (animal), Wisconsin Card Sorting Test (WSCT) and Tower of Hanoi (TOH). Results Compared with normal controls, the patients with post-concussion syndrome were significantly lower NAA/Cr and NAA/(Cho+Cr) ratios in left prefrontal lobe (P < 0.05). The NAA/Cr ratio in left prefrontal was significantly positive correlated with total scores of verbal fluency (r = 0.66, P < 0.05), categories of WSCT (r = 0.54,P < 0.05) and total score of TOH(r = 0.58, P < 0.05). The NAA/Cr ratio was significantly negative correlated with total errors (r = -0.53, P < 0.05) and persistent errors (r = -0.47, P < 0.05) of WSCT and mean executive time of TOH(r = -0.67, P < 0.05). Conclusions The metabolic levels of NAA in left prefrontal lobe in patients with post-concussion syndrome is significantly decreased , it is one cause of impaired executive functions.
