The purpose of this study was to investigate whether the genetic polymorphisms of UDP-glucuronosyltransferase(UGT1A7), an important phase II biotransformation enzyme, and X-ray repair cross-complementing group 1(XRCC1), a pivotal DNA-repair gene, were related to the risk of HCC in Northeast China. Methods: One hundred and thirty six HCC patients and one hundred and thirty six frequency-matched controls were included in this hospital-based case-control study. Genotypes of UGT1A7 and XRCC1 were determined using allele-specific polymerase chain reaction (AS-PCR) and PCR-restriction fragment length polymorphism (RFLP), and for which the odds ratio (OR) with 95% confidence interval (95% CI) were calculated. Results: The proportion of UGT1A7 low enzymatic allele (*2 or *3) was higher in HCC patients than those in controls. The UGT1A7*1/*2 and *3/*3 genotypes were associated with higher HCC risk (OR=2.09, 95%CI: 1.10-3.97; OR=5.67, 95%CI: 1.76-18.30, respectively). The XRCC1 codon 399 Arg/Gln genotype could also elevate HCC risk (OR=2.16, 95% CI 1.29-3.61). In addition to polymorphisms of UGT1A7 and XRCC1, multivariate logistic regression analysis demonstrated that other significant independent factors associated with HCC were HBV infection (OR=68.07, 95%CI: 28.03-165.26), HCV infection (OR=30.97, 95%CI: 8.06-118.94) and family history of HCC (OR=10.62, 95%CI: 2.22-50.77). Conclusion: The study shows that the polymorphisms of UGT1A7 and XRCC1 are associated with HCC risk. Determination of the polymorphisms of UGT1A7 and XRCC1 may provide an important clue to preventive measure against HCC.展开更多

Methods In this retrospective study, all 12 cases which were diagnosed with suspected prenatal CCAM over the period in the hospital were analyzed. Information on diagnosis time, types and progression of the lesions during pregnancy, the additional abnormalities, and the outcome of pregnancies were recorded. Results The positive rate of ultrasonic detection of CCAM was about 1.01‰ (1/11 124) before 28 gestation weeks. There were 1 case of type I (8%), 2 cases of type II (17%) and 9 cases of type III (75%). Nine pregnancies were terminated and 2 cases were confirmed by pathology. Three neonates were alive and without any symptom now. Conclusions Type III is the major type. Ultrasound examination during 20-28 weeks and following up, prenatal consultation, chromosome examination of fetus, delivery with a pediatrician standing by, and all suspected neonates being investigated are recommended.展开更多
