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:In the present study,Bac-to-Bac baculovirus expression system was used to obtain recombinant human Cosmc extracellular domain protein,which can lay the foundation for the research about the structure and function of Cosmc protein in vitro,and simultaneously provide ideas for the research of O-glycosylation and related diseases. Methods: The Cosmc extracellular domain ( Cosmc-ED) gene was cloned into a transfer vector pFastBac1 to form the recombinant donor plasmid pFastBac1-Cosmc ED, which was transformed into competent cells DH10Bac. By using blue-white selection and PCR analysis,we could obtain recombinant shuttle vector rBacmid-Cosmc ED. Then, the recombinant gene DNA of rBacmid-Cosmc ED was used to transfect Sf-9 mediated by cationic lipid formulation,and the recombinant baculovirus bacmid was obtained,which was further used to infect the serum-free cell Sf-9 to express Cosmc-ED in the supernatant. Then the protein of interest was detected by SDS-PAGE and Western blot and purified with Ni-NTA affinity column. Results:SDS-PAGE and Western blot analysis showed a specific band about 33 kD,consistent with the interest protein. Mass spectrometry results further prove that the protein was Cosmc extracellular domain protein. Conclusion: Human Cosmc-ED protein can be successfully expressed in Sf-9 insect cells and laid basis for subsequent studies.

Scores of comprehensive quality after departmental rotation and satisfaction rates of nursing students to teaching method in these two groups were evaluated. ResultsThe experimental group was significantly better than the control group ( P＜0.05 ), and the difference was statistically significant. ConclusionThe clinical pathway can significantly improve the quality of nursing practice teaching.

OBJECTIVE The purpose of this study is to clarify the association between Cu levels and heart failure(HF)using a meta- analysis approach. METHODS We searched articles in the PubMed, EMbase, CNKI, Wanfang ,VIP and CBM Database published as of August 2016. The case control study on the relationship between serum copper levels and HF were collected and read and extracted by two independent researchers. A Meta analysis was conducted using Stata 12.0 software. RESULTS A total of twenty- one eligible articles, including 893 HF and 654 control subjects, were enrolled. The Meta analysis showed that serum copper levels in HF were higher than control group〔SMD=0.881, 95%CI: (0.487 ,1.264), Z=4.5, P<0.001〕. The sensitivity analysis indicated that the results were reliable. Begg's tests did not find the existence of publication bias. CONCLUSION This meta-analysis indicates that there is a significant association between high Cu serum level and HF.

In this study, the psbA-trnH sequence as DNA barcode was used to evaluate the accuracy and stability for identification pteridophyte medicinal material Pyrrosiae Foliumas from adulterants. Genomic DNA from 106 samples were extracted successfully. The Kimura 2-Parameter (K2P) distances and ML tree were calculated using software MEGA 6.0. The intra-specific genetic distances of 3 original plants were lower than inter-specific genetic distances of adulterants. The ML tree indicated that Pyrrosiae Folium can be distinguished from its adulterants obviously. Therefore, the psbA-trnH sequence as a barcode of the pteridophyte, can accurately and stably distinguish Pyrrosiae Folium from its adulterants.
