E,/, patients were accompanied withremarkably low levels of high density lipoproteincholesterol (HDLC) and its subforms. But in E,/#patients there were only slight changes in levelsof VLDLC and low density lipoprotein cholesterol (LDL--C).CONCLUSION Different apoE phenotype patientswith gallstones have different cheracteristics ofdyslipidemia and the average level of serum lipids in patients with gallstones are higher thansubjects without gallstones in the same apoEgene phenotype. EZ allele is possibly one of thedangerous factors in the lithogenesis of cholecystolithiasis.展开更多
