Application of the national diagnostic criteria of occupational mercury poisoning / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To investigate the clinical manifestation of patients with renal injury induced by chronic mercury intoxication and the application of the diagnostic criteria of occupational mercury poisoning.</p><p><b>METHODS</b>The clinical data of 8 patients with chronic occupational mercury intoxication were analysed and evaluated.</p><p><b>RESULTS</b>All the observed clinical signs of chronic mercury intoxication correspond with the items of the diagnostic criteria of occupational mercury poisoning. The increasing beta2-MG was one of the clinical manifestations of renal injury induced by chronical mercury intoxication. The renal injury obviously was dose-dependent and reversible.</p><p><b>CONCLUSIONS</b>The national diagnostic criteria of occupational mercury poisoning is practically valuable. The renal injury induced by chronic mercury intoxication should not be neglected.</p>

The correlation between ICAM-1 gene K469E polymorphism and coronary heart disease / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the correlation between intercellular adhesion molecule1 (ICAM1) gene K469E polymorphism and coronary heart disease(CHD) in Han Chinese population.</p><p><b>METHODS</b>Using the methods of polymerase chain reaction-restrictive fragment length polymorphism (PCR-RFLP), 173 CHD patients and 141 controls were analyzed for the polymorphism, genotype and allele distribution of ICAM1 gene K469E.</p><p><b>RESULTS</b>The distribution of ICAM1 genotypes was in Hardy-Weinberg equilibrium. The frequency of KK genotype in CHD group was significantly higher than that in control (64.2% vs 48.9%, P<0.01). Similarly, the frequency of K allele in CHD group was significantly higher than that in control (79.2% vs 69.9%, P<0.01). With Logistic Regression Analysis ruling out the influences of age, gender and other CHD risk factor, the homozygous individual with KK genotype was 2.35 folds of KE or EE genotype one suffering from CHD (OR: 2.35, 95%CI: 1.03-5.36, P<0.05).</p><p><b>CONCLUSION</b>ICAM1 gene K469E polymorphism is associated with CHD risk of Han Chinese population, the K allele may serve as a genetic risk factor of coronary heart disease.</p>
