ABSTRACT: Single Nucleotide Polymorphisms Other Than Factor V Leiden are Associated with Coagulopathy and Osteonecrosis of the Femoral Head in Chinese Patients
Project description:Single nucleotide polymorphisms (SNPs) of factor V Leiden have been associated with osteonecrosis of the femoral head (ONFH) in Caucasians but remains controversial in Asians. We used an SNP microarray to screen 55 loci of factor V gene in patients with ONFH of Chinese. Significantly different candidate SNPs at 14 loci were analyzed in 146 patients and 116 healthy controls using MALDI-TOF (matrix-assisted laser desorption/ionization time-of-flight) mass spectrometry and gene sequencing. The factor V Leiden (rs6025) was not found in all participants. Six SNP loci (rs9332595, rs6020, rs9332647, rs3766110, rs10919186, and rs12040141) were confirmed with significant differences in patients but not in controls. The rs6020 G-to-A polymorphism was found in 88.9% of the patients. In addition, a high percentage (84.7%) of the patients had an abnormal coagulation profile that included hyperfibrinogen, elevated fibrinogen degradation products, elevated D-dimer, abnormal protein S, abnormal protein C, or a decrease in anti-thrombin III. Patients with the rs6020 G-to-A polymorphism (mutation) had a higher risk (odds ratio: 4.33; 95% confidence interval: 1.36-13.76) of having coagulation abnormalities than did those without the mutation (wild-type) (p = 0.008). Our findings suggested that the rs6020 polymorphism might be the genetic trait that accounts for the higher prevalence of ONFH in the Chinese population than in Westerners. Exposure to risk factors such as alcohol and steroids in patients with the rs6020 polymorphism causes coagulation abnormalities and, subsequently, thromboembolisms in the femoral head. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from peripheral blood samples. SNP genotype analysis of Affymetrix 6.0 Chip. SNP arrays was performed for 22 Chinese patients with Osteonecrosis of the Femoral Head.

Project description:We recently showed that microRNA different profile from Trauma-induced osteonecrosis of the femoral head (TIONFH) and healing patients.
Project description:Buxue tongluo Pills(BTP) are a pill commonly used to treat osteonecrosis of the femoral head, but its composition and mechanism are unclear. As a result, we analyzed the components of BTP by LC-MS/MS.
Project description:Early diagnosis and prompt treatment are the key to prevent collapse and delay Steroid-induced Osteonecrosis of the Femoral Head(SONFH) progression.The aim of this study was to identify potential biomarkers for the diagnosis of SONFH, so to improve the efficiency of early diagnosis. Microarray analysis based on the 30 SONFH patients and 10 non-SONFH patients(following steroid administration) was performed to screen SONFH-related genes.
Project description:Early diagnosis is crucial to increase the chances of conservation treatment for patients with steroid-induced osteonecrosis of the femoral head (SIONFH). This study aimed to identify serum peptides as potential biomarkers to diagnose SIONFH.
Project description:data-independent Acquisition (DIA) proteomics technology was utilized to identify differentially expressed proteins within bone tissue in Osteonecrosis of the femoral head
