| prevalence of and risk factors for hepatitis c virus infection among blood donors in chengdu, china. | the objectives of the study were to estimate the prevalence of anti-hepatitis c virus (hcv) positivity among blood donors from chengdu, china, and to determine risk factors associated with infection. in this study, data were collected from volunteer blood donors between july 2006 and june 2007. anti-hcv test was performed in 119,518 donors. to identify risk factors associated with hcv infections a case-control study was conducted in 305 unique hcv-seropositive blood donors and 610 seronegative d ... | 2011 | 21328375 |
| [hepatitis c viruses infection situation in the human population of six provinces in china]. | to investigate the seroprevalence of hepatitis c viruse infection in the human population in six regions of beijing, heilongjiang, shandong, ningxia, gansu and sichuan in china. | 2011 | 22734232 |

| [hcv genotype distribution in southwest china and its influence on patients' response to pegylated-interferon α-2a plus ribavirin therapy]. | to study the distribution of hepatitis c virus (hcv) genotype in sichuan population and to investigate the effects of hcv genotypes on the viral response of hepatitis c patients treated with pegylated interferon α-2a plus ribavirin as well as the relationship between hcv genotype and the severity of disease. | 2015 | 26480661 |
| five near full-length hepatitis c virus sequences were isolated from hiv coinfected idus of china. | hiv and hcv share transmission routes including contaminated blood transfusion, sexual intercourse, and needle-sharing in injection drug users (idus). we obtained five near full-length genome sequences (nflgs) of hcv isolated from five hiv-1 coinfected idus in sichuan and xinjiang province, china. by conducting reconstruction of neighbor-joining (nj) phylogenetic tree, our results revealed that the five isolates are different genotypes (1b, 3a, 6a and 6n). the amino acid substitutions(170i) in x ... | 2017 | 28075146 |
| phylogenetic analysis of hcv subgenotypes in patients from sichuan province in china based on the ns5b region. | the classification of hepatitis c virus (hcv) genotypes is of clinical importance as it may help to predict drug therapy responses and estimate treatment duration. the classical method of hcv subgenotype classification is whole genome sequencing (wgs). however, the high cost and time-consuming nature of wgs limits its usage in clinical practice. a number of studies have been conducted to confirm whether specific regions of hcv could replace wgs in the classification of hcv subgenotypes. in the p ... | 2015 | 26311523 |
