Vinay K. Kapoor

Frontiers of Medicine 2015, Volume 9, Issue 4,   Pages 508-511 doi: 10.1007/s11684-015-0418-7

Abstract:

Bile duct injury is a common complication of cholecystectomy.The timing of bile duct injury repair remains controversial.Most patients with bile duct injury present with bile leak and sepsis; thus, early repair is not recommendedand endoscopic stenting are the mainstays of treatment of bile leak because they convert acute bile duct

Effects of hydralazine and valproate on the expression of E-cadherin gene and the invasiveness of QBC

Hong LI, Shaoqin CHEN, Yi SHU, Yongjun CHEN, Ying SU, Xin WANG, Shengquan ZOU

Frontiers of Medicine 2009, Volume 3, Issue 2,   Pages 153-157 doi: 10.1007/s11684-009-0034-5

Abstract: To clarify the effect of DNA methylation and histone deacetylase inhibitors on the expression of the E-cadherin gene and the invasiveness of the QBC cells, the QBC cells were separately treated with hydralazine, valproate, or combination of the two drugs. The mRNA expression of E-cadherin was examined with reverse transcription-polymerase chain reaction (RT-PCR), the protein of the gene with Western blotting. The methylation status of the promoter region of the gene was detected with methylation-specific PCR (MSP). The invasiveness of QBC cells was detected with transwell assay. It was found that the promoter region of the E-cadherin gene of QBC cells was hypermethylated. Valproate alone could not contribute to demethylation of the gene, whereas hydralazine could make them to be partly demethylated. However, the methylation status of the gene could be thoroughly reversed by using valproate and hydralazine in combination. What’s more, it was confirmed that the E-cadherin gene of QBC cells could not be transcriptionally reactivated by Valproate alone, whereas hydralazine alone could induce moderate reexpression of the gene. However, using valproate and hydralazine in combination could result in robust reexpression of the E-cadherin gene ( =0.000). Likewise, the invasiveness of the QBC939 cells was sharply decreased by treatment with two drugs in combination and slightly decreased with one drug alone. It could be concluded that the two drugs have synergistic effect on the demethylation and reexpression of the E-cadherin gene of QBC cells, and also on the reduction of the invasiveness of the QBC939 cells.

Strategic Study of CAE 2002, Volume 4, Issue 11,   Pages 42-49

Abstract:

This paper reviews and analyses the major findings of research during the last 15 years in Harbin Institute of Technology, on bias coal combustion technologies. Five problems in China's coal combustion in boilers of power plant are given. The theory and characteristics of air-surrounding-fuel flow of bias coal combustion technologies are introduced and analysed. Industrial experiments tested the theory of airsurrounding-fuel .To greatly decrease the NOx emission, the paper points out the development of these technologies in the future.
