ABSTRACT

Heart development protein with EGF-like domains 1 (HEG1) is a novel mucin-like membrane protein with a long O-glycosylation region and EGF domain. HEG1 plays critical roles in embryo development and cardiogenesis, and is closely related to the occurrence and progression of malignant tumors. Here this article demonstrates the research progress on HEG1 in cardiovascular formation and tumor development in recent years, to inspire new ideas for the pathogenesis, diagnosis and treatment of related diseases.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the distribution of hepatitis B virus (HBV) genotypes in Qingdao, and the relationship of HBV genotypes with the serum HBV-DNA levels and HBV YMDD spontaneous mutation of patients, then to discuss the clinical significance.</p><p><b>METHODS</b>Hepatitis B virus genotypes and YMDD spontaneous mutation of 144 patients were detected by real time PCR (Taqman probe), then the results were analyzed by statistical method.</p><p><b>RESULTS</b>Of the 144 patients, 130 (90.3%) were genotype C, 12 (8.3%) were genotype B, and 2 (1.4%) were neither genotype B nor genotype C; 33 (22.9%) were detected to have YMDD mutation, and 25 (75.5%) were YVDD positive, 3 (9.1%) were YIDD positive, 5 (15.2%) were YVDD and YIDD positive. There were no significant differences between clinical diagnosis, serum HBV-DNA levels, YMDD spontaneous mutation and HBV genotypes (P > 0.05).</p><p><b>CONCLUSION</b>Genotype C is the dominant position for HBV genotype in Qingdao. Untreated patients with chronic hepatitis B have YMDD spontaneous mutation. HBV genotypes have no association with YMDD spontaneous mutation and the development of diseases.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the relationship between interleukin 10 (IL10) gene -627 polymorphisms and serum IL10 level and early-onset coronary heart disease (CHD).</p><p><b>METHODS</b>The genotype and allele frequency of IL10 gene -627 site was assayed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). DNA samples were obtained from 163 patients with CHD and 112 controls. Serum IL10 level was detected by ELISA.</p><p><b>RESULTS</b>No significant difference was found in the distribution of IL10 genotype and allele frequency between the healthy controls and the patients with CHD; Chi-square values were 1.9324 and 1.5703 respectively, P > 0.05. Stratification analyses based on different sex still found no significant difference in the distribution of IL10 genotype and allele frequency between the healthy controls and the CHD patients; the Chi-square values in male groups were 1.2708 versus 0.8595, and in female groups were 0.8254 versus 0.7127, P > 0.05. Serum IL10 level showed significant differences among AA genotype, AC genotype and CC genotype, but no significant difference was noted between healthy controls and CHD patients.</p><p><b>CONCLUSION</b>These results suggest that IL10 gene -627 polymorphisms are not associated with an increased risk of CHD, but it might assume a role in IL10 gene expression.</p>
