| 1 | Tyrosine kinase of insulin-like growth factor receptor as target for novel treatment and prevention strategies of colorectal cancer显示文摘AIM: To investigate the antineoplastic potency of the novel insulin-like growth factor 1 receptor (IGF-1R) tyro- sine kinase inhibitor (TKI) NVP-AEW541 in cell lines and primary cell cultures of human colorectal cancer (CRC). METHODS: Cells of primary colorectal carcinomas were from 8 patients. Immunostaining and crystal violet stain- ing were used for analysis of growth factor receptor pro- tein expression and detection of cell number changes, respectively. Cytotoxicity was determined by measuring the release of the cytoplasmic enzyme lactate dehydro- genase (LDH). The proportion of apoptotic cells was determined by quantifying the percentage of sub-G1 (hypodiploid) cells. Cell cycle status reflected by the DNA content of the nuclei was detected by flow cytometry. RESULTS: NVP-AEW541 dose-dependently inhibited the proliferation of colorectal carcinoma cell lines and primary cell cultures by inducing apoptosis and cell cycle arrest. Apoptosis was characterized by caspase-3 activa- tion and nuclear degradation. Cell cycle was arrested at the G1/S checkpoint. The NVP-AEW541-mediated cell cycle-related signaling involved the inactivation of Akt and extracellular signal-regulated kinase (ERK) 1/2, the upregulation of the cyclin-dependent kinase inhibitors p21Waf1/CIP1 and p27Kip1, and the downregulation of the cell cycle promoter cyclin D1. Moreover, BAX was upregu- lated during NVP-AEW541-induced apoptosis, whereas Bcl-2 was downregulated. Measurement of LDH release showed that the antineoplastic effect of NVP-AEW541 was not due to general cytotoxicity of the compound. However, augmented antineoplastic effects were ob-served in combination treatments of NVP-AEW541 with either 5-FU, or the EGFR-antibody cetuximab, or the HMG-CoA-reductase inhibitor fluvastatin. CONCLUSION: IGF-1R-TK inhibition is a promising novel approach for either mono- or combination treatment strategies of colorectal carcinoma and even for CRC che- moprevention. | Michael Hpfner Andreas P Sutter Alexander Huether Viola Baradari Hans Scherübl | 2006 | World Journal of Gastroenterology2006，12，35： | 10 |

| 3 | Distribution and effects of polymorphic RANTES gene alleles in HIV/HCV coinfection - A prospective cross-sectional study显示文摘AIM: Chemokines and their receptors are crucial for immune responses in HCV and HIV infection. RANTES gene polymorphisms lead to altered gene expression and influence the natural course of HIV infection. Therefore,these mutations may also affect the course of HIV/HCV coinfection.METHODS: We determined allele frequencies of RANTES-403 (G→A), RANTES-28 (C→G) and RANTESIN1.1 (T→C) polymorphisms using real-time PCR and hybridization probes in patients with HIV (n = 85), HCV (n= 112), HIV/HCV coinfection (n = 121), and 109 healthy controls. Furthermore, HIV and HCV loads as well as CD4+ and CD8+ cell counts were compared between different RANTES genotypes.RESULTS: Frequencies of RANTES-403 A, RANTES-28 G and RANTES-IN1.1 C alleles were higher in HIV infected patients than in healthy controls (-403: 28.2% vs 15.1%,P = 0.002; -28: 5.4% vs 2.8%, not significant; IN1.1:19.0% vs 11.0%, P = 0.038). In HIV/HCV coinfected patients, these RANTES alleles were less frequent than in patients with HIV infection alone (15.4% P = 0.002;1.7%; P = 0.048; 12.0%; not significant). Frequencies of these alleles were not significantly different between HIV/HCV positive patients, HCV positive patients and healthy controls.CONCLUSION: All three RANTES polymorphisms showed increased frequencies of the variant allele exclusively in patients with HIV monoinfection. The finding that the frequencies of these alleles remained unaltered in HIV/HCV coinfected patients suggests that HCV coinfection interferes with selection processes associated with these alleles in HIV infection. | Golo Ahlenstiel Agathe Iwan Jacob Nattermann Karin Bueren Jürgen K Rockstroh Hans H Brackmann Bernd Kupfer Olfert Landt Amnon Peled Tilman Sauerbruch Ulrich Spengler Rainer P Woitas | 2005 | World Journal of Gastroenterology2005，11，48： | 3 |
| 4 | An efficient descriptor model for designing materials for solar cells显示文摘An efficient descriptor model for fast screening of potential materials for solar cell applications is presented.It works for both excitonic and non-excitonic solar cells materials,and in addition to the energy gap it includes the absorption spectrum(α(E))of the material.The charge transport properties of the explored materials are modelled using the characteristic diffusion length(Ld)determined for the respective family of compounds.The presented model surpasses the widely used Scharber model developed for bulk heterojunction solar cells.Using published experimental data,we show that the presented model is more accurate in predicting the achievable efficiencies.To model both excitonic and non-excitonic systems,two different sets of parameters are used to account for the different modes of operation.The analysis of the presented descriptor model clearly shows the benefit of includingα(E)and Ld in view of improved screening results. | Fahhad H Alharbi Sergey N Rashkeev Fedwa El-Mellouhi Hans P Lüthi Nouar Tabet Sabre Kais | 2015 | npj Computational Materials2015，，1： | 3 |

| 6 | Quality control measures for lowering the seroconversion rate of hemodialysis patients with hepatitis B or C virus显示文摘BACKGROUND: Hemodialysis (HD) patients are at high risk of infection by hepatitis B virus (HBV) or hepatitis C virus (HCV). The present study was designed to determine the impact of quality control measures on the prevention of transmission of blood-borne viruses. METHODS: A total of 6182 adult maintenance HD patients from all HD units in Zhejiang Province were recruited on January 1, 2007. The baseline demographic and clinical characteristics were recorded and all patients were followed up until death or survival at 4 years later. The Quality Control Standards of Hemodialysis were gradually implemented in HD units. The HBV or HCV seroconversion rates of the recruited patients were calculated and compared every year during the observation period. RESULTS: The prevalence of HBV was 8.3% at the beginning of the study, and 6.6% for HCV. With the implementation of the HD quality control measures, the HBV seroconversion rate tended to decrease year by year (χ 2 =6.620, P=0.085), and the HCV seroconversion rate decreased significantly (χ 2 =10.41, P=0.015). Compared with the data in 2007, the HBV seroconversion rate (χ 2 =4.204, P=0.040, relative risk ratio 0.393, 95% CI 0.156-0.991) and the HCV seroconversion rate (χ 2 =7.373, P=0.007, relative risk ratio 0.386, 95% CI 0.189-0.787) decreased significantly in 2010. CONCLUSION: Quality control measures for HD decreased the seroconversion rates of HBV or HCV in HD patients, showing that updated quality control measures reduce the risk for transmission of blood-borne viruses in the HD population. | Jing Yuan,Yi Yang, Fei Han, Ping Zhang, Xiao-Ying Du, Hua Jiang and Jiang-Hua Chen The Kidney Disease Center, First Affiliated Hospital, Zhejiang University School of Medicine (Yuan J, Yang Y, Han F, Zhang P, Du XY, Jiang H and Chen JH) and Hemodialysis Quality Control Center of Zhejiang Province (Yuan J, Zhang P, Du XY and Chen JH), Hangzhou 310003, China | 2012 | Hepatobiliary & Pancreatic Diseases International2012，11，3： | 2 |
