Objective To explore the roles of MircroRNA-217 ( Mir-217 ) , silent information regulator 1 (Sirt1), and hypoxia-inducible factor-1α(HIF-1α)in high glucose-induced inflammation and fibrosis in rat glomerular mesangial cells( RMCs) . Methods RMCs were pre-incubated with a Sirt1 activator resveratrol prior to high glucose treatment or transfected with Sirt1 small interfering RNA( siRNA) , HIF-1αsiRNA, and Mir-217 inhibitor. Real-time PCR was used to analyze the expressions of Mir-217, Sirt1 mRNA, and HIF-1α mRNA; Western blot was used to observe the protein expressions of Sirt1, HIF-1α, connective tissue growth factor(CTGF), endothelin-1(ET-1), and fibronectin( FN) . Enzyme-linked immunosorbent assay was applied to detect protein expression of transforming growth factor-β1(TGF-β1)and vascular endothelial growth factor(VEGF). Results High glucose increased Mir-217, HIF-1α, CTGF, ET-1, FN, TGF-β1, and VEGF expressions(all P<0. 01), while decreased Sirt1 expression. In addition, Mir-217 gene silencing or 25μmol/L resveratrol suppressed high glucose-stimulated expressions of HIF-1α, CTGF, endothelin-1, FN, TGF-β1, and VEGF(all P<0. 01). Conclusion Mir-217 mediates high glucose-induced inflammation and fibrosis in RMCs via Sirt1/HIF-1αsignal pathway. This study provides new evidence to clarify the protective mechanisms of Sirt1 in diabetic nephropathy.

Objective To investigate the standardized treatment of 33 children with thalassemia and their family financial burden registered in Bao'an district, Shenzhen city, and to provide basic information for formulating health policy for the government. Methods In 2009, preliminary investigations on 39 registered families with thalassemia children were conducted by telephone, and a household survey was made to collect treatment and economic status by questionnaire on 33 children. Results Among 33 cases of thalassemia children, 21 cases(63.7%) were severe anemia, 5 cases( 15.1%) in need of care or special care, and 25 cases(75.8%) were difficult or unable to maintain standardized treatment. The average family monthly income and expenditure was (4060 ± 2002) and (4926 ± 2991) yuan, respectively. The average monthly treatment costs were (2665 ± 1872) yuan, and the average debt amounted to (64 600 ± 53 940) yuan. Fifteen families[60.0%(15/25)] would reduce the times of blood transfusions or iron transpirations when they encountered revenue deficiency. Conclusions The heavy economic burdens on families with children thalassemia result in inadequate or interrupted treatment on sick children and affect their survival and quality of life, which should be taken more attention and social care.

Aim To investigate the role of TGF-β3 in the anti-proliferation effect of ursolic acid(UA)in co-lon cancer cells and the possible molecular mechanism underlying this effect.Methods We introduced crys-tal violet staining,flow cytometry and Western blot as-say to determine the effect of UA on proliferation and apoptosis in HCT1 1 6 cells.The levels of TGF-β3, Smad2 /3 and β-catenin in HCT1 1 6 cell were evaluated by RT-PCR and Western blot.Finally,TGF-β3 inhibi-tor and recombinant adenovirus,and luciferase reporter assay were used to analyze the possible mechanism through which TGF-β3 mediated the anti-cancer effect of UA in HCT1 1 6 cells.Results UA inhibited the proliferation and induced apoptosis apparently in HCT1 1 6 cells.UA down-regulated TGF-β3 both in mRNA and in protein level.Meanwhile,UA decreased the phosphorylation of Smad2 /3 concentration depend-ently,although no significant effect was found on the total protein level of Smad2 /3 in HCT1 1 6 cells.Over-expression of TGF-β3 attenuated the inhibitory effect of UA on the proliferation of HCT1 1 6 cells,while the TGF-β3 inhibitor potentiated this effect. UA sup-pressed the transconduction of Wnt/β-catenin signaling in HCT1 1 6 cells through decreasing the level of β-catenin.Exogenous expression of TGF-β3 increased the level of β-catenin and partly reversed the UA-in-duced decrease of β-catenin.However,TGF-β3 inhib-itor potentiated the inhibitory effect of UA on β-catenin in HCT1 1 6 cells.Conclusion The anti-proliferation activity of UA in colon cancer may be partly mediated through down-regulating TGF-β3 to suppress Wnt/β-catenin signaling at least.
