The objective of this study was to investigate the association of four single-nucleotide polymorphisms (SNPs) of the cannabinoid receptor 2 ( Chinese patients with OP were recruited between March 2011 and December 2015 from our hospital. In this study, a total of 1267 post-menopausal female patients (631 OP patients and 636 control patients) were selected. The mean age of all subjects was 69.2 years (sd 15.8). A generalized multifactor dimensionality reduction (GMDR) model and logistic regression model were used to examine the interaction between SNP and obesity on OP. For OP patient-control haplotype analyses, the SHEsis online haplotype analysis software (Objectives
Methods
Corticosteroid use has been implicated in the
development of osteonecrosis of the femoral head (ONFH). The exact mechanism
and predisposing factors such as age, gender, dosage, type and combination
of steroid treatment remain controversial. Between March and July
2003, a total of 539 patients with severe acute respiratory syndrome (SARS)
were treated with five different types of steroid. There were 129
men (24%) and 410 women (76%) with a mean age of 33.7 years (21
to 59). Routine screening was undertaken with radiographs, MRI and/or
CT to determine the incidence of ONFH. Of the 129 male patients with SARS, 51 (39.5%) were diagnosed
as suffering from ONFH, compared with only 79 of 410 female patients
(19.3%). The incidence of ONFH in the patients aged between 20 and
49 years was much higher than that of the group aged between 50
and 59 years (25.9% (127 of 491) Cite this article:
