The implementation of cancer genome scientific program has promoted the diagnosis, prevention and tar-get treatment of diseases at molecular level with massive cancer genome data accumulated. Effective mining and use of cancer genome data have thus become the focus in the field of cancer genome. The cancer genome was annotated and demonstrated according to the mining of high-throughput cancer genome data from American National Cancer Research Center, namely the disease-named entity and drug-named entity were identified from the gene function descriptive text and the mined high-throughput data were annotated from their clinical application, in order to help scientific workers to find the relationship between diseases, drugs and genes in scientific literature.

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.

Objective To study the relationship among depression associated type 2 deabetes mellitus (T2DM) and personality and quality of life.Methods A total of 246 cases of hospitalized T2DM patients were investigated by schedule tables:self-rating depression scale (SDS),Eysenck personality questionaire (EPQ) and adjusted diabetes-specific quality of life scale (A-DQOL).According to the results of SDS,patients were divided into depression group (171 cases) and non-depression group (75 cases).Correlation analysis and regression analysis were carried out for the collected data.Results There were differences in satisfaction,influence,anxiety Ⅰ,anxiety Ⅱ,neuroticism and extraversion between the two groups(P ＜ 0.05 or P ＜ 0.01).Depression extents was related to the quality of life,neuroticism,extraversion and course(r =-0.243-0.392,P ＜ 0.05 or P ＜ 0.01).Anxiety Ⅱ,satisfaction and course enter the regression equation of depression (β =-0.205-0.322,P ＜ 0.05 or P ＜ 0.01).Conclsion Anxiety Ⅱ,satisfaction and course are key factors inducing depression in T2DM.Neuroticism and extroversion may be the predisposing personality characteristics in T2DM patients with depression.In clinical work,it is helpful for treatment by changing personality and mood of patients.
