The colorectal adenoma-carcinoma sequence describes the stepwise progression from normal to dysplastic epithelium and then to carcinoma. Only a small proportion of colorectal adenomas (CRAs) progress to colorectal carcinomas (CRCs). Endoscopic intervention is currently being used on patients with high grade dysplasia CRAs, with diameters of >1 cm, or(More)
AIM To determine whether HBV with the same characteristics causes dissimilar mutations in different hosts. METHODS Full-length HBV genome was amplified and linked with pMD T18 vector. Positive clones were selected by double-restriction endonuclease digestion (EcoRI and HindIII) and PCR. Twenty seven clones were randomly selected from an asymptomatic(More)
Hepatitis B virus (HBV) infection is highly prevalent in China. To identify the genotypes of HBV in the southern Yunnan Province of China, full-length HBV genomes were extracted from 1 Dai and 4 Hani HBV carriers and linked with the pMD T-18 vector. For each patient, 3-10 clones were sequenced directly and a consensus sequence was created. Genotypic and(More)
OBJECTIVE To explore the relationship between HBV infection and the genotypes and allele frequencies of CIITA G-944C gene polymorphism in three minority populations (Jinuo, Dai and Aini population) in Xishuangbanna district, Yunnan province. METHODS Polymerase chain reaction and sequencing method were used to study the genotypes and allele frequencies(More)
