There is a complicated association between the liver and diabetes mellitus.Diabetes mellitus may cause various forms of liver damage,such as nonalcoholic fatty liver disease (NAFLD),hepatic cirrhosis,hepatocellular carcinoma,liver abscess,and liver transplant complications.With the growing epidemic of diabetes mellitus,this review investigates diabetes mellitus induced liver damage.

Objective To study the length of hypertension history and its related factors in patients with both ischemic cerebral vascular disease(ICVD) and hypertension.Methods The profile of hypertension history in ICVD patients from our hospital between 1990 and 1999 was summarized.Hypertension history meant the time interval between onset of first symptomatic ICVD and establishment of diagnosis of hypertension.The related factors' influence on the length of hypertension history was analyzed by means of multiple linear regression model.Results In ICVD patients with hypertension,the mean length of hypertension history was 14.29?10.63 years,the median was 11 years.In multiple linear regression model,increased age when hypertension was diagnosed,diabetes mellitus,smoking,peasant(army man as control group) were independent factors that shortened hypertension history.Antihypertensive treatment independently lengthened hypertension history.Conclusion The length of hypertension history varies greatly,50% of patients developed the first ICVD in 11 years after the diagnosis of hypertension was established .Coexisting smoking and diabetes mellitus hasten while control of arterial blood pressure postpone onset of ICVD in patients with hypertension.

BACKGROUND:Bone formation and development are reported to be regulated by bone morphogenetic protein2(BMP2)-induced Osterix expression. OBJECTIVE:To investigate the regulatory effect of BMP2/Osterix signaling pathway on differentiation of preosteoblasts in mice. METHODS:mRNA and protein expression of Osterix wasdetermined by real-time RT-PCR and western blot assay, respectively at various time points after mouse preosteoblasts were treated with BMP2. pcDNA3.1/myc-Osterix eukaryotic expression vector was constructed and transducted into preosteoblasts, and then mRNA expression of alkaline phosphatase, bone sialoprotein, and matrix extracelular phosphoglycoprotein wasdetected by real-time RT-PCR after transduction and BMP2 treatment. RESULTSANDCONCLUSION:Osterix mRNA expression was up-regulated when treated with BMP2 in mouse preosteoblasts, and reached the peak at 24 hours. In addition, the protein expression of Osterix was increased after BMP2 treatment. Alkaline phosphatase, bone sialoprotein, and matrix extracelular phosphoglycoprotein mRNA expression wasup-regulated after transfection of mouse preosteoblasts with pcDNA3.1/myc-Osterix eukaryotic expression vector and BMP2 treatment. Our results indicate that BMP2 regulates the synthesis of genetic markers of osteogenesis,such asalkaline phosphatase,matrix extracelular phosphoglycoproteinviaup-regulating Osterix expression in mouse preosteoblasts, suggesting BMP2/Osterix signaling pathway plays a critical role in bone development.

Objective To study the effect of UHRF1 expression inhibition by RNA interference on the radiosensitivity of esophageal cancer cell line TE-1 and its mechanism.Methods Short hairpin RNA (shRNA) targeting UHRF1 gene was introduced into TE-1 cells by lentivector-mediated transfer.The cells were divided into three groups:non-transfected group,negative control (NC)-shRNA-transfected group,and UHRF1-shRNA-transfected group.The mRNA and protein expression levels of UHRF1 in TE-1 cells were measured by RT-PCR and Western blot before and after transfection.After transfection and X-ray radiation,the radiosensitivity of TE-1 cells was evaluated by colony formation assay; the cell cycle and cell apoptosis were determined by flow cytometry; the γ-H2AX (as a marker of DNA damage) level was measured by Western blot.Results After transfection with UHRF1-shRNA,the mRNA and protein expression levels of UHRF1 were significantly decreased in TE-1 cells,as compared with those in the NC-shRNA-transfected group and non-transfected group (0.11 vs 0.96 and 0.98,F =124.21,P =0.000;0.10 vs 0.89 and 0.94,F =125.25,P =0.000).The UHRF1-shRNA-transfected group had sensitization enhancement ratios of 1.53 (D0 ratio) and 1.95 (Dq ratio).X-ray radiation could cause G2/M arrest and increase apoptotic rate and γ-H2AX expression in TE-1 cells.Compared with the two control groups,the UHRF1-shRNA-transfected group showed significantly less G2/M arrest (F =500.15,P =0.000),a significantly higher apoptotic rate (F =100.10,P =0.000),and significantly higher residual γ-H2AX expression (F =61.00,P =0.000) at 24 hours after X-ray radiation.Conclusions RNA interference can effectively inhibit the UHRF1 expression and enhance the radiosensitivity of TE-1 cells.The mechanism may be related to cell cycle regulation,cell apoptosis,and DNA damage repair.

objective Using iodimetric analysis of dual-energy CT,to explore the dual perfusion amount and proportion of hepatic artery and portal vein in different hepatic lobes on normal living bodies.Methods A total of 77 patients without hepatic diseases underwent contrast-enhanced upper abdomen dual-energy CT scanning.The raw data were transferred to the workstation for postprocessing.ROI were selected,then the iodine content in arterial phase,portal phase and delay phase were calculated automatically.The differences of these measures (iodine content and hepatic artery to portal vein perfusion ratio of the left hepatic lobe,right hepatic lobe and caudate lobe) in the left,fight and caudate lobe of liver were detected by using ANOVA test.Results The iodine concentration in the caudate lobe was(851 ± 35)μg/L from hepatic artery and (2912 ± 78) μg/L from portal vein.The iodine concentration in the left hepatic lobe was (445 ± 34) μg/L from hepatic artery and (2373 ± 77) μg/L from portal vein.The iodine concentration in the right hepatic lobe was(504 ± 30)μg/L from hepatic artery and(2515 ± 78) μg/L from portal vein.The perfusion condition (amount of blood supply) of caudate lobe showed a significant statistic difference from the left and right hepatic lobe (P ＜ 0.05),and the amount of blood supply from both sources were more than those of the left and fight hepatic lobes.There was no significant statistic difference in the amount of hepatic artery and portal vein blood supply between the right and left hepatic lobe(P ＞ 0.05).The proportions of blood supply from hepatic artery and portal vein (hepatic artery/portal vein) were different among the three hepatic lobes,which was (28.41 ± 3.42) ％ in left lobe,(35.76-± 5.80) ％ in fight lobe and (49.92 ±4.63)％ in caudate lobe,respectively(F =5.36,P ＜0.01).Conclusion Dual-energy CT can be used to study the dual-perfusion condition of the liver.On normal living bodies,the hepatic artery and portal vein perfusion in caudate lobe are different from those in left and right lobes.
