Methods: Fragments of ApoE gene forthex-on containing codon 112 and 158 polymorphic locus were amplified by PCR, and then digested untilCfo I endonuclease. Genotypes and alleles frequencies of 168 healthy persons in Jiangsu area werecalculated. The effects of ApoE genotypes and alleles on serum lipids, lipoproteins andapolipoproteins variation were analyzed. Results: The effects of ApoE alleles on total cholesterol(TC), law density lipoprotein-cholesterol (LDL-C), ApoB was: along a decreasing gradientε_4>ε_3>ε_2. The effect of ε_4 allele was to increase serum levels of TC, LDL-C and ApoB, andthe ε_2 allele had an effect opposite to that of ε_4 allele. Conclusion: ApoE polymorphism is anindependent genetic factor on individual serum levels of lipids and apolipoproteins.展开更多

The most common allele was 3’β 37. followed by 3’β39 with frequencies of 0. 362 and 0. 296, respectively. This model of allele distribution was coincident with the results form different ethnic groups, but the relative frequencies of alleles were different. In comparison with the allele frequencies between the patients and controls,alleles bigger than 3’β39 (3’VNTR-B) were significantly more common among the patients than among the controls (P<0. 001). Moreover. in the CHD group patients with plasma levels of TC≥3.88 mmol/L,LDL-C≥2. 59 mmol/L and HDL-C<l. 16mmol/L had significantly higher frequencies of 3’ VNTR-B allele (P<0. 01). Therefore,it is suggested that 3’ VNTR-B allele might be involved in the development of coronary atherosclerosis, presumably through their influences on lipid metabolism.This study supported by “8. 5” grant from Ministry of PublicHealth.展开更多

We determined LPL gene polymorphisms affecting the enzyme at Ser447stop, as well as Hind Ⅲ and Pvu Ⅱ polymorphisms using PCR techniques. PCR products were characterized by PCR-RFLP and direct sequencing. Polymorphisms were examined for association with clinical features in UC patients. Genotype frequencies for LPL polymorphisms were also compared between UC patients and controls.RESULTS: In patients with onset at age 20 years or younger, C/G and G/G genotypes for Ser447stop polymorphism were more prevalent than C/C genotype (OR = 3.13, 95% CI = 0.95-10.33). Patients with H^+/- or H^-/- genotype for Hind Ⅲ polymorphism also were more nu merous than those with H^+/+ genotype (OR = 2.51, 95% CI = 0.85-7.45). In the group with H^+/+ genotype for Hind Ⅲ polymorphism, more patients had serum triglyceride concentrations over 150 mg/dL than patients with H^+/- or H^- genotype (P 〈 0.01, OR = 6.46, 95% CI = 1.39-30.12). Hypertriglycemia was also more prevalent in patients with P^+/+ genotypes for Pvu Ⅱ polymorphism (P 〈 0.05, OR = 3.0, 95% CI = 1.06-8.50). Genotype frequency for LPL polymorphism did not differ significantly between UC patients and controls.展开更多

Our data suggest that the polymorphisms at the LPL gene,as the linkage markers with an aetiologic mutation at or around LPL gene,may constitute one of the genetic determinants for the population variation in plasma TG levels,as well as for the common dyslipidemia in Chinese population.展开更多

Methods: Polymerase chain reaction and gene sequencing, single nucleotide polymorphisms of ApoE gene were used to analyze 33 cases of patients with ACI and 35 controls. Results: The frequencies of ApoE gene single nucleotide polymorphisms 465C/G, 462C/G and 451delC in the ACI group were significantly higher than those in the control group (P<0.05). The prevalence of polymorphism 486G/T in the control group was significantly higher than that in the ACI group ( P = 0.011) . Conclusions: 465C/G,462C/G and 451delC polymorphisms might be associated with ACI.486GT allele might have protective effect on the pathogenesis of ACI.展开更多

To research the relations between low- density lipoprotein receptor- related protein gene (LRP) polymorphism, butyrylcholinesterase gene (BchE) polymorphism and Alzheimer’s disease (AD) in Chinese. Methods. The gene polymorphisms of LRP and BchE were genotyped in 38 AD cases and 40 controls with polymerase chain reaction- restriction fragment length polymorphism (PCR- RFLP) methods. AD groups were classified according to the LRP C/C genotype and compared with matched controls. Results. AD group had higher frequencies of C/C homozygote (81.6% vs 60.0% , P< 0.05) and of C allele (89.5% vs 76.3% , P< 0.05),with no significant difference between any of these LRP genotypes classified AD groups and their respective control groups. Conclusions. A positive correlation was found between LRP gene polymorphism and AD, but not between BchE gene polymorphism and AD in Chinese AD cases.展开更多

In this study, the apoE genotypes, by means of PCR AFLP assay in 42 patients with cortical cerebral infarction and 85 healthy controls were detected. The results showed that the apoE ε 3/3 genotype was more prevalent in the controls (55.29%), and ε 3/4 genotype was more common in the patients (57.14%). The frequency of ε 4 allele was more predominate in the patients than that in the controls. The ε 3/4 genotype or ε 4 allele was associated with 2.44 or 2.31 fold increase in the risk of cortical cerebral infarction. Therefore, it was suggested that apoE ε 4 allele is a genetic factor of susceptibility to cerebral infarction, which supported the hypothesis of the association between apoE polymorphism and atherosclerotic cardio cerebrovascular disorders.展开更多

The results showed that the frequency of ApoE E4/3 genetype in AD group was significantly higher than that in con- trol (P<0. 05). Among these three groups, ApoE 4 allele frequency in AD group was significantly higher than that in control (P<0. 01 ) and MID group (P<0. 05). Among the three ApoE alleles, the risk ratio of ApoE E4 allele in AD group was 4. 114(p<0. 01 ). There was statistically significant (P<0. 05) as the increasing of ApoE 4 gene dose in AD. It suggests that ApoE is related to AD of Chineses and it might be a genetics index of early diagnosis for AD.展开更多
