Résumé

<p><b>OBJECTIVE</b>To study the effects of ApoE gene polymorphism on anti-inflammatory action of Xuezhikang Capsule.</p><p><b>METHODS</b>One hundred and two patients with hyperlipidemia (as the treated group) and one hundred healthy volunteers (as the control group) were enrolled in the case-control study. Total DNA of the peripheral blood was extracted and ApoE genotypes were determined by PCR sequence analysis. The serum levels of tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), and high sensitivity C reactive protein (hs-CRP)were measured in all subjects. The changes of TNF-alpha, IL-6, and hs-CRP were detected before and after 6-week Xuezhikang Capsule treatment, thus analyzing the correlation between ApoE gene polymorphism and changes of each inflammatory factor.</p><p><b>RESULTS</b>The frequency of E3/3 genotype was 86% (86/100 cases)in the control group, significantly higher than that of the treated group (62.7%, 64/102 cases). The frequency of E3/4 genotype was 6% (6/100 cases) in the control group, significantly lower than that of the treated group (21.6%, 22/102 cases; both P < 0.05). Compared with the control group, the serum levels of TNF-alpha, IL-6, and hs-CPR were higher in the treated group before treatment (P < 0.05). In hyperlipidemia patients with E3/4 + E4/4 genotype, the serum level of TNF-alpha was higher than that of E3/3 genotype (P < 0.05); the serum level of IL-6 was higher than that of E2/E2 + E2/E3 genotype (P < 0.05); the serum level of hs-CRP was higher than that of E2/E2 + E2/E3 and E3/E3 genotype (P < 0.05). But there was no statistical difference in the serum levels of TNF-alpha, IL-6, or hs-CPR between E3/3 and E2/E2 + E2/E3 genotype. After 6-week intervention of Xuezhikang Capsule, the serum levels of TNF-alpha, IL-6, and hs-CRP were lower in the treated group (P < 0.05), but the serum levels of TNF-alpha and IL-6 were still higher than those of the control group (P < 0.05). But there was no statistical difference in the decrement of TNF-alpha, IL-6, or hsCRP among E2/E2 + E2/E3, E3/E3, or E3/4 + E4/4 genotypes (P > 0.05).</p><p><b>CONCLUSIONS</b>The distribution of ApoE gene polymorphism is different between the hyperlipidemia patients and the healthy people. Chronic inflammatory reactions exist in hyperlipidemia patients, especially in those with e4 allele. Xuezhikang Capsule showed anti-inflammatory effects, but ApoE gene polymorphism did not affect its effects.</p>

Résumé

<p><b>OBJECTIVE</b>To study the correlation between Apo E gene polymorphism and patients with coronary heart disease (CHD) of phlegm-stasis syndrome (PSS).</p><p><b>METHODS</b>78 CHD patients were assigned to PSS (49 cases) and non-phlegm-stasis syndrome (NPSS). Polymorphisms of Apo E gene in 78 CHD patients and 100 healthy subjects were detected by complete DNA sequencing.</p><p><b>RESULTS</b>Five gene types as E3/3, E4/4, E2/ 3, E2/4, and E3/4 were detected in the two groups. The frequencies of genotype E3/3 and epsilon 3 allele were significantly lower in CHD patients than in the healthy subjects (P<0.01). But the frequencies of genotype E3/4 and epsilon 4 allele were significantly higher in CHD patients than in the healthy subjects (P<0.01). In CHD patients, the frequencies of genotype E2/4 + E3/4 + E4/4 and epsilon 4 allele were higher in PSS than in NPSS.</p><p><b>CONCLUSIONS</b>Apo E epsilon 4 allele was a susceptible allele to CHD, which was closely correlated to CHD PSS. It was inferred that it might be one of main susceptible alleles for CHD PSS.</p>

Résumé

<p><b>OBJECTIVE</b>To study the mutation patterns of epithelial growth factor receptor (EGFR) exon 18, 19 and 21 in Chinese non-small-cell lung cancers (NSCLC).</p><p><b>METHODS</b>Somatic mutation in samples of 32 cases without Iressa-treatment were compared with that in 10 volunteers blood control. The mutations were identified for the forward and reverse sequence chains for the tyrosine kinase domain of the EGFR gene, followed by DNA template abstraction and Touchdown PCR.</p><p><b>RESULTS</b>Nine types of mutation were found in sequences of 7 cases among the 32 non-small cell lung carcinoma tissues, namely, five reported mutation within exon 19, and two new heterozygous mutations, L833V and H835L within exon 21, and two intron polymorphism. These results showed a mutation rate of 9/32 (28.1%) in Chinese with NSCLC, and of 31.6% in lung adenocarcinomas.</p><p><b>CONCLUSION</b>EGFR mutation rate in Chinese with NSCLC is consistent with those of Asian women reported in the literature but new mutation points in Chinese were presented as L833V and H835L. The mutation rate is in concordance with release rate of NSCLC obtained by Gefitinib treatment in Chinese.</p>
