Purpose:To study if tamoxifen (TAM) can induce growth arrest and apoptosis of ER negative MA782 mouse breast cancer cell line and to explore the molecular mechanisims. Methods:MA782 cells were cultured in RPMI 1640 medium with TAM.The proliferative activity of cells was detected by MTT methods, and cells apoptosis by flowcytometric methods. The expression of cyclin D1, CDK4 and TGF ?1 proteins was detected by immunohistochemical methods, the semi quantification of protein expression was analyzed by pathological image analysis software.Results:TAM can induce growth arrest and apoptosis of cells. ICC results showed that MA782 cells were ER negative. There was no change of cell cycle regulators in cells with 2 ?mol/L TAM. After 48、72h with 6 ?mol/L or 10 ?mol/L TAM, the level of cyclin D1 proteins decreased from 132.5?0.02 to 129.67?0.03、126.18?0.03(6 ?mol/L) and 109.1?0.01、73.56?0.02(10 ?mol/L),CDK4 proteins decreased from 107.2?0.01 to 91.23?0.02、76.21?0.03(6 ?mol/L)and 83.52?0.02、72.03?0.01(10 ?mol/L), while TGF ?1 proteins increased from 59.72?0.02 to 83.2?0.04、121.75?0.03(6 ?mol/L)and 96.83?0.02、139.01?0.05(10 ?mol/L),The difference was significant( P

Purpose To summarize the clinical and echocardiographic characteristics of congenital quadricuspid aortic valves (QAV) so as to improve the understanding of QAV and the accuracy of preoperative diagnosis.Materials and Methods The clinical and echocardiographic data of 7 patients with QAV at the First Affiliated Hospital of Nanchang University were retrospectively studied,and the features such as the aortic valve (AV) leaf number,echo,shape,opening and closing movements,and its hemodynamics were observed and compared with surgical follow-ups.Results Five out of the 7 patients had chest tightness,chest pain,fluster,shortness of breath,and 2 others had no discomfort.The echocardiography presented that all the cases had moderate or severe aortic valve regurgitation.4 patients were diagnosed as QAV,2 patients were not diagnosed definitely,and the rest 1 was misdiagnosed.6 patients underwent aortic valve replacement and were all confirmed with QAV,among whom 2 patients were combined with infective endocarditis,and 1 patient was with aortic dilatation.All the surgical operations were successful and the patient's physical conditions were good after surgery.Conclusion Echocardiography plays an important role in diagnosis of aortic valve,but it is possible to be missed or misdiagnosed.Most QAV patients have good prognosis,but close follow-ups are needed when QAV is combined with other complex deformity or has induced secondary damages.

Purpose To detect the expression of Snai2 mRNA in gastric carcinoma and normal gastric mucosa and analyze its significance.Methods Total RNA was extracted with TRIzol from 30 cases of gastric carcinoma and mRNA was transcribed reversely into cDNA.The expression of Snai2 mRNA was examined by real-time PCR; then mRNA probes were prepared, the expression of Snai2 mRNA was detected by in situ hybridization on a tissue array,including normal gastric mucosa (20 cases) and gastric carcinoma (100 cases).Results Real-time PCR data showed they had different expression in different degrees of differentiation of the cancer: the poorer differentiation, the more expression (P<0.05). In situ hybridization results showed the positive rate in the carcinoma (54.2%) was higher than normal tissue (27.8%), with statistically significant difference (P<0.05).There were different positive rate in different degrees of differentiation: the poorer differentiation,the higher positive rate, but it had no statistical significance (P>0.05).Conclusions Snai2 could be a biomarker of malignant degree and disease progression,and used as a useful tool for evaluation of prognosis.

Objective To investigate the expression and significance of cellular inhibitor of protein phosphatase 2A (CIP2A), bcl-2 and p63 in papillary thyroid cancer (PTC). Methods Using immunohistochemistry to detect the expression of CIP2A, bcl-2 and p63 in 30 cases of nodular goiter (NG), 30 cases of thyroid adenoma (TA) and 57 cases of PTC [including classical PTC (cPTC) 20 cases, papillary microcarcinoma (PMC) 20 cases, follicular thyroid papillary carcinoma (FPTC) 7 cases]. Results In NG group, TA group and PTC group, positive rates of CIP2A were 0, 0 and 94.74 % (54/57), respectively. The differences were statistically significant. In NG group, TA group and PTC group, positive rates of bcl-2 were 16.67 % (5/30), 13.33 % (4/30) and 85.96 % (49/57), respectively. The differences were statistically significant. In each group, positive rates of p63 were 6.67% (2/30), 3.33% (1/30) and 5.26% (3/57), respectively, no significant difference among them. In PTC, expression of CIP2A and bcl-2 were significantly higher than in NG and TA (χ2 = 105.56, P= 0.00; χ2 = 58.95, P= 0.00). Furthermore, the expression of CIP2A and bcl-2 had correlation in PTC (r=0.94, P=0.00). The expression of CIP2A, bcl-2 and p63 had no significantly difference among all the PTC subtype (χ2 values were 2.02, 2.64, 1.85; all P> 0.05). The expression of CIP2A, bcl-2 and p63 was not associated with patients'age, sex, site, lymph node metastasis (all P>0.05).

Objective To identify the gene locus and the mutation of DSRAD (double-stranded RNA adenosine deaminase) in a Chinese dyschromatosis symmetrica hereditaria(DSH) family. Methods After confirming the diagnosis of the DSH proband, the genomic DNA was extracted from the whole blood samples of every members of the pedigree. The DSRAD gene intervals were localized by linkage analysis and haplotype reconstruction. The mutation of DSRAD was detected by direct sequencing. Results The candidate gene was localized at the 1q region, consistent with the reported region. The direct sequencing results showed that there was a CAA→TAA transition at exon 2 of DSRAD in all affected family members, which consequently led to a nonsense mutation of Gln517Ter. Conclusion A nonsense mutation is found in the Chinese DSH family.

Objective To summarize the echocardiographic characteristics and clinical signiifcance of prenatal diagnosis of coronary artery ifstula (CAF). Methods Images and follow-up results of ifve fetuses with CAF diagnosed by fetal echocardiography between January, 2011 and December, 2012 in our department were reviewed. Results Echocardiographic characteristics of CAF were a dilated coronary artery in the four chamber view and the left ventricular outlfow tract view. Track the course of the dilated coronary artery can conifrm the oriifce of the ifstula. Among the ifve cases, the oriifce of the ifstula included the aortic root of left ventricular outlfow tract, right atrium side of interatrial septum, the entrance of superior vena cava to right atrium, right ventricular apex and right ventricle cone. The colour Doppler lfow imaging showed turbulence in the dilated coronary artery. The spectral Doppler with the sampling gate in coronary artery showed the characteristic bidirectional lfow pattern. One case was associated with other complex intracardiac abnormalities and one case with persistent left superior vena cava. Among the ifve cases of CAF diagnosed by fetal echocardiography, one case was missed and four cases were conifrmed by postnatal echocardiography. Conclusion Coronary artery ifstula has special fetal echocardiographic characteristics. The fetal echocardiography plays an important role in early detection, diagnosis and treatment of CAF.

BACKGROUND:Previous studies have demonstrated that normal rat liver homogenate supernatant can induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels with partial hepatocyte functions. However, whether fibrotic liver homogenate supernatant can work or how the inducing effect is remains unclear. OBJECTIVE:To investigate the differentiation potential of human umbilical cord mesenchymal stem cels into hepatocytes under the normal liver and fibrotic liver microenvironment in vitro. METHODS:Liver fibrosis was induced in the SD rats by repeated intraperitoneal injections of 3% thioacetamide at a dose of 200 mg/kg body mass, twice a week for 4 weeks, and then fibrotic liver tissues and normal liver tissues were used to prepare liver homogenate supernatants. Passage 3 human umbilical cord mesenchymal stem cels were used and divided into standard control group (cels were cultured in DMEM/F12 with 10% fetal bovine serum), fibrotic liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 50 g/L fibrotic liver homogenate supernatants), normal liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 100 g/L normal liver homogenate supernatants). The morphological changes of the cels in each group were recorded under inverted microscope; the protein levels of CK18, AFP, CYP3A4, CYP2E1, CYP2D6 and TPH2 were evaluated using western blot assay. Furthermore, the concentration of albumin in the cels was measured. RESULTS AND CONCLUSION:After a 7-day inducement, the stem cels in liver homogenate supernatants groups lost their fusiform shape and changed into hepatocyte-like cels with the morphous of round shape. Compared with the standard control group, the hepatocyte-like cels in the two liver homogenate supernatants groups exhibited human hepatocyte biomarkers, CK18 and AFP. The standard control group cels could express a little amount of CYP2E1, while cels in the two liver homogenate supernatants groups could express CYP3A4, CYP2E1, CYP2D6, TPH2. Compared with the standard control group, the expression level of CYP2E1 in the two liver homogenate supernatants groups increased significantly (P < 0.01), and however, the relative levels of CYP3A4, CYP2E1, CYP2D6, TPH2 in the two liver homogenate supernatants groups showed no statistical significance (P > 0.05). At the same time, compared with the standard control group, the concentration of albumin in the two liver homogenate supernatants groups markedly increased (P < 0.01), but there was no difference between the two liver homogenate supernatants groups (P > 0.05). Experimental findings demonstrated that both of normal liver tissue and fibrotic liver tissue microenvironments could induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels. To achieve the same effect, compared with normal liver tissue, fibrotic liver tissue required lower concentrations, suggesting that fibrotic liver tissue microenvironment may be more conducive to differentiation of umbilical cord mesenchymal stem cels into hepatocytes.
