Objective To investigate the effect of influenza virus on the expression of collagen triple he-lix repeat containing 1 (CTHRC1). Methods A549 cells were infected with influenza virus. mRNA and protein levels of CTHRC1 were determined by RT-PCR and Western blot , CTHRC1 levels in the cell supernatants and sera of influenza virus infected patients were determined by enzyme-linked immunosorbent assay (ELISA). The difference of CTHRC1 levels between healthy controls and HCV patients was analyzed. Results Compared with controls, mRNA and protein levels of CTHRC1 were higher in A549 cells infected with H3N2. Serum CTHRC1 levels were higher in influenza virus infected patients than in healthy controls (P < 0.05). Conclusion Influenza virus can promote the synthesis and secretion of CTHRC1.

Objective To understand the changes in the level of osteocalcin (OC) in patients with type 2 di-abetes mellitus (T2DM) and discuss the correlation between the changes and glycated hemoglobin (HbA1c), fasting blood glucose (FBG),thyroid globulin (TG),total cholesterol (TC),high-density lipoprotein (HDL C),low density lipoprotein (LDL C),fasting insulin (FINS),and fasting C peptide (FCP) and so on.Methods 108 cases of T2DM patients were collected from group T2DM and 92 healthy subjects as healthy control group.Fasting venous blood was taken from the subjects and serum levels of OC were detected by chemilumi-nescence.HbA1c,FBG,TG,TC,HDL-C,LDL-C,FINS and FCP levels were detected,and Pearson correlation and logistic regression were used to analyze the relationship between OC and other indicators.Results The level of OC in the T2DM group was significantly lower than that in the control group,and the difference was statistically significant [(14.98 ± 10.16)ng/mL vs.(18.20 ± 6.67)ng/mL,P<0.05].There was a signifi-cant negative correlation between OC and HbA 1c and FBG in T2DM patients (P< 0.01),and a significant positive correlation with HDL C(P< 0.01);Logistic regression analysis showed that HbA 1c was an inde-pendent influence factor of serum OC(P<0.01).Conclusion The level of OC in peripheral blood of T2DM patients was significantly decreased.OC level was closely related to blood glucose and blood lipids,and it had a certain effect on the prevention and evaluation of T2DM.
