Produced by bone cells and stored in the matrix.bone ceil growth factor can contribute to the regulation of bone growth.Gene regulation has its role in bone development.Many factors of this kind have been founded recently.They play their role during the bone formation and absorption processes in the way of autocrine and paracrine.The genes of core binding factor α_1(Cbfα_1)and estrogen receptor α(Erα)have been the recent years'hot factors that are related to the bone development,Gene polymorphism refers to variation on gene level which often occurs in the non-coding domain or the domain bearing no important regulatory function in gene order.This article reviewed the research status of the relation between Cbfα_1 and Erα gene polymorphism with bone development.

Objective To detect the levels of homocysteine (Hcy) and anti-phospholipid antibodies (APLA) in the hematoplasma of the patients with deep venous thrombosis (DVT), discuss the reason of DVT recurrence and search for the predictors of it. Methods Sixty cases with DVT in our department from January 2001 to April 2003 were collected, which were divided equally into two groups as primary and recurrent, and first degree relative of the 30 DVT recurrent patients were also collected. The author established a control group using 30 cases of out-patient clinic without varicose veins of lower extremity or insufficient venae profundae. Hcy was detected with fluorescence polarization immunoassay (FPIA) and APLA 〔anticardiolipin antibody, ACLA (IgG, IgM); lupus antibody (LA)〕were detected with enzyme linked immunosorbent assay (ELISA). Odds ratios (OR) were also calculated to assess the relative risk of each study group. Results The values of Hcy and ACLA (IgG, IgM) in the primary group and recurrent group were both significantly higher than those of control group and first degree relative group of DVT recurrent patients (P

Purpose To assess the left ventricular global systolic function changes using three-dimensional speckle tracking imaging (3D-STI) in female patients with subclinical hypothyroidism (SHT) undergoing L-thyroxine treatment. Materials and Methods Thirty-eight female patients with SHT and 40 healthy female volunteers of the same age (control group) were selected, all the SHT patients received L-thyroxine therapy and were followed for 1 year after euthyroid status was achieved; all the participants underwent blood biochemical examinations, complete conventional echocardiographic and 3D-STI examinations, left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVEDs), interventricular septal depth (IVSd), left ventricular posterior wall depth (LVPWd), left atrial diameter (LAD), diastolic mitral flow spectrum of A peak, left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), and left ventricular ejection fraction (LVEF) of the two groups were compared, and the correlation of parameters of three dimensional left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), global area strain (GAS), and thyroid stimulating hormone (TSH) with each parameter was analyzed. Results IVSd and LVPWd in the study group were higher than those of the control group (t=3.30 and 3.64, P<0.05). Compared with the control group, GLS, GCS, GRS and GAS of left ventricular of SHT patients in the study group were significantly lower (t=8.60, 11.95, 9.78 and 5.92, P<0.05) before treatment. GLS, GCS, GRS and GAS of SHT patients improved after L-thyroxine therapy, and the difference was statistically significant (t=6.91, 9.41, 6.46 and 4.31, P<0.05).TSH level was negatively correlated with E/A ratio and E (r= - 0.39 and - 0.42, P<0.05), and also negatively correlated with GLS, GCS, GRS and GAS (r= - 0.38, - 0.56, - 0.33 and - 0.41, P<0.05). Conclusion Left ventricular global systolic function changes of SHT patients before and after L-thyroxine treatment can be evaluated properly using 3D-STI.
