Alcohol-induced osteonecrosis of femoral head (ONFH) is one of the most important pathogenesis of nontraumatic ONFH. However, its pathogenesis mechanism is still unknown. Osteoprotegerin (OPG) has been implicated in multiple functions including blocking osteoclast maturation, controlling vascular calcifications, promoting tumour growth and metastasis. This study is focussed on OPG gene polymorphisms associated with alcohol-induced ONFH. A total of 509 participants (209 patients and 300 normal individuals) were recruited, and we selected 13 single-nucleotide polymorphisms (SNPs) to evaluatethe association between genetic susceptibility variants and alcohol-induced ONFH by using the χ² test and genetic model analysis. Overall, OPG SNPs (rs1485286, rs1032128 and rs11573828) were confirmed the strongest increasing risks on alcohol-induced osteoporosis of femoral head in recessive model (rs1485286: OR, 1.71; 95% CI, 1.07–2.73; P = 0.025 for T/T); (rs1032128: OR, 1.73; 95% CI, 1.08–2.77; P = 0.022 for G/G); (rs11573828: OR, 3.89; 95% CI, 1.02–14.85; P = 0.033 for T/T). SNP rs11573856 was considered as a protective effect to the occurrence of alcohol-induced ONFH, while adjusted for age and gender in dominant and log-additive models (rs11573856: adjusted OR, 0.60; 95% CI, 0.37–0.96; P = 0.033 for G/A–A/A); (rs11573856: adjusted OR, 0.63; 95% CI, 0.41–0.96; P = 0.042). We conclude that OPG gene polymorphisms were associated with the occurrence of alcohol-induced ONFH.

Genetic analysis of drug metabolizing phase-I enzymes CYP3A4 in Tibetan populations

The enzymatic activity of CYP3A4 results in broad interindividual variability in response to certain pharmacotherapies. The present study aimed to screen Tibetan volunteers for CYP3A4 genetic polymorphisms. Previous research has focussed on Han Chinese patients, while little is known about the genetic variation of CYP3A4 in the Tibetan populations. Here, we adopted DNA sequencing to investigate the promoter, exons and surrounding introns, and 3'-untranslated region of the CYP3A4 gene in 96 unrelated healthy Tibetan individuals.We identified 20 different CYP3A4 polymorphisms in the Tibetan population, including two novel variants (21824 A>G and 15580 G>C). In addition, we also determined the allele frequencies of CYP3A4*1Aand CYP3A4*1H were 82.29% and 28.13%, respectively. CYP3A4*1P and *1G were relatively rare with frequencies of only 1.04% and 0.52%, respectively. Our results provide information on CYP3A4 polymorphisms in Tibetan individuals which may help to optimize pharmacotherapy effectiveness by providing personalized medicine to this ethnic group.

In this study, we examined and validated how common variants contribute to susceptibility to chronic obstructive pulmonarydisease (COPD) in the Han Chinese population. Here, we genotyped 18 nucleotide polymorphisms and evaluated their associationwith COPD using chi-square test and genetic model analysis (246 COPD patients and 350 controls), and found threeSNPs that might cause a predisposition to COPD. Both rs3025030 and rs3025033 are located on chromosome 6 in
