Objective To explore the changes in serum concentrations of irisin,vaspin and reactive oxygen species (ROS) in patients with type 2 diabetes mellitus (T2DM) and metabolic syndrome (MS),and to investigated the correlation of irisin and vaspin with clinical parameters of MS.Methods A total of 260 T2DM patients were enrolled.Age and gender were recorded,anthropometrics,biochemical parameters,and levels of irisin,vaspin and ROS in fasting serum were measured,and homeostatic model assessment of insulin resistance (HOMA-IR) calculated.Wilcoxon rank sum test,correlation analysis,Logistic regression analysis,multiple linear regression analysis and receiver operating characteristic (ROC) curve analysis were performed.Results Compared to T2DM patients without MS,T2DM patients with MS had lower serum level ofirisin [male:112.81 (86.96-191.84) μg/Lvs.156.23 (110.61-225.97) μg/L,female:141.09 (77.52-175.55) μg/L vs.172.15 (95.69-240.37) μg/L,P ＜0.01],higher levels of vaspin and ROS [male:1.13 (0.95-1.38) μg/Lvs.0.36 (0.21-0.82) μg/L,1 540 (1 250-1 860) kU/Lvs.1 020 (920-1 350) kU/L;female:1.52 (1.13-1.80) μg/Lvs.0.51 (0.47-1.08) μg/L,1 650 (1 320-1 940) kU/Lvs.1 120 (980-1 420) kU/L,P ＜0.01].In the T2DM patients,serum irisin level was negatively correlated with vaspin (r =-0.382,P ＜ 0.01) and ROS (r =-0.410,P ＜ 0.01),while vaspin was positively correlated with ROS (r =0.400,P ＜ 0.01).Multiple linear regression analyses showed that irisin was significantly correlated with body mass index (BMI),waist circumference and triglyceride,while vaspin was correlated with gender,BMI,and waist circumference (all P ＜ 0.05).Logistic regression analysis revealed that irisin,vaspin and ROS were all associated with MS (OR =0.77,95 ％ CI 0.608-0.978;OR=1.39,95％ CI 1.252-1.539;OR=1.38,95％ CI1.112-1.718,all P＜0.05).ROC analysis demonstrated that irisin and vaspin had significant area under the curve (AUC =0.931,P ＜0.01;AUC =0.777,P ＜ 0.01) for the prediction of MS.Conclusions Serum irisin level was significantly decreased,while vaspin and ROS were significantly increased in T2DM patients with MS.Irisin and vaspin were associated with clinical presentations of MS,suggesting that irisin and vaspin might be valuable predictors of MS.

Objective To explore the biological effects of estrogen (17β-E2) on the proliferation and migration of human skin fibroblast (HSFB).Methods HSFBs were isolated and cultured by enzyme digestion.The fourth generation of HSFBs were adopted; (1) the proliferating effect of diverse concentrations of 17β-E2 and 17β-E2+ ICI-182780 on HSFBs was determined with MTT method at 24,48,72,96 h; (2) the influence of 17β-E2 and ICI-182780 to HSFBs cycle distribution were determined with flow cytometry; (3) the migration effect of diverse concentrations of 17β-E2 and 17β-E2+ICI-182780 on HSFBs was determined at 24,48,and 72 hours after the creation of the scratch-wound in vitro.Results (1) The proliferating speed of HSFBs in 10-10mol/L 17β-E2 group (group A)was the highest of all at 48,72,96 h,which was higher than that in ICI-182780+10-10mol/L 17β-E2 group (group B) and control group (group C) (P＜0.01) ;(2) the HSFBs during the S phase in group A was more than that in groups B and C (P＜0.01),while the HSFBs during the G0/G1 phase was less than that in groups B and C (P＜0.01); (3) the migrating effect of HSFBs in 10-8mol/L 17β-E2 group (group D) was the highest of all at 48 h,which was higher than that in ICI-182780+10-10mol/L control group (group E)and control group (group F) (P＜0.01).Conclusions The concentration of 10-10mol/L estrogen has the strongest effect of promoting proliferation and that of 10-8mol/L has the strongest chemotaxis; ICI-182780 can abate the above effect effectively.

The epitope-G1 gene of Bovine ephemeral fever virus (BEFV) glycoprotein was synthesised by PCR and cloned into expression vector pPIC9K to construct recombinant plasmid pPIC9K-G1. Then the pPIC9K-G1 was linearized and transformed into Pichia pastoris GS 115. The recombinant P. pastoris strains were selected by a G418 transformation screen and confirmed by PCR. After being induced with methanol, an expressed protein with 26 kDa molecular weight was obtained, which was much bigger than the predicted size (15.54 kDa). Deglycosylation analysis indicated the recombinant G1 was glycosylated. Western blot and ELISA tests, as well as rabbit immunization and specificity experiments indicated that the target protein had both higher reaction activity and higher immunocompetence and specificity. The recombinant G1 protein could be used as a coating antigen to develop an ELISA kit for bovine ephemeral fever diagnosis.

The Cardiac Troponin T and I are highly cardiac specific biochemical markers of myocardial injury. They are very sensitive markers to detect all kinds of myocardial injury, and are able to distinguish myocardial injury and skeletal injury. Furthermore, They are independent predictor of future cardiac events. Such markers are now widely used in the clinic practice. It is prospective to use them in Forensic Medical Science.
