ABSTRACT
Objective:To explore the association between thyroid hormones and visceral fat area(VFA) in the patients with type 2 diabetes.Methods:A total of 729 patients with type 2 diabetes, who joined National Metabolic Management Center(MMC) through Ningbo First Hospital from March, 2018 to July, 2019, were enrolled in this study. Blood tests were taken to assess their thyroid hormones and biochemical indexes. VFA and subcutaneous fat area(SFA) were obtained through bioelectrical impedance analysis. Statistics were later analyzed by Spearman correlation analysis and multivariate linear regression. Results:Spearman correlation analysis showed that VFA were positively correlated with T 3、FT 3( r=0.225 and 0.211, P<0.01), and VFA were inversely correlated with FT 4( r=-0.112, P<0.01). No correlation was found between VFA and either of T 4 or TSH( P>0.05). Multivariate linear regression analysis indicated that VFA was independently correlated with FT 4 and FT 3( P<0.01). An increment of 1 pmol/L in FT 4 was associated with 1.759 cm 2 increase in VFA, and increment of 1 pmol/L in FT 3 was associated with 3.256 cm 2 decrease in VFA. Conclusion:VFA in patients with type 2 diabetes are correlated with FT 3 and FT 4.
ABSTRACT
Objective To investigate the effects of p38 MAPK inhibitor on glutamate (Glu), glutamine (Gln), taurine amino acid (Tau), glycine (Gly) and gamma aminobutyric acid (GABA) in hippocampus of rats with vascular dementia (VD).Methods Twenty-four healthy male SD rats were randomly divided into sham operation group, VD model group and inhibitor group. VD model was established by permanent ligation of bilateral carotid artery method, and the sham operation group stripping bilateral carotid artery but not ligation. Rats of the inhibitor group were injected p38 MAPK inhibitor SB202190 after the establishment of VD model. Morris water maze was used to evaluate the learning and memory function of rats. The samples of DG region of hippocampus were collected by microdialysis, and the contents of amino acids were detected. Results The learning and memory abilities were significantly better in sham operation group and p38 MAPK inhibitor group than those of VD model group. The latency time was significantly shorter in p38 MAPK group than that of VD model group. The time of locating the platform quadrant and the number of crossing the original platform were significantly higher in sham operation group and p38 MAPK inhibitor group than those of VD model group (P <0.05). Compared with sham group, the levels of Glu, Gln and Tau were significantly lower, and Gly and GABA were significantly higher, in VD group and p38 MAPK inhibitor group (P<0.05). Compared with VD group, Glu, Gln and Tau were significantly increased, Gly and GABA were significantly decreased in p38 MAPK inhibitor group (P<0.05). Conclusion p38 MAPK inhibitor has protective effect on VD hippocampal injury, which may be related to its ability to inhibit VD-induced abnormal secretion of amino acids and regulate the secretion of various amino acids.

ABSTRACT
Objective To investigate the effects on IL-6 and PGE2 expression in wear-particles-induced osteoblast cells by blocking calcium phosphatase (Cn)/ activated T nuclear factor (NFAT) pathway. Methods Fetal Sprague-Dawley rats were used in this study. Osteoblast were prepared from the calvariae of rats . Osteoblast cells were incubated in four group according to different supplementation:(1) neither Ti particles nor 11R-VIVIT (Control group), (2) only Ti particles (Ti group), (3) both Ti particles and 11R-VIVIT (Ti/VIVIT group), and (4) only 11R-VIVIT (VIVIT group). Cells were incubated for 96 hours and the expression of NFATc1 protein was detected by western blot. The expression of IL-6 and PGE2 in liquid supernatant of osteoblast were detected at 6, 24 and 96 hours by ELISA. Results The expression of NFATc1 in the Ti group was higher than that in the Control group (P < 0.01), but in Ti/VIVIT group that was significantly lower than in the titanium particle group (P < 0.01). The IL-6 and PGE2 expression in the supernatant of the Ti group were significantly increased than those in the control group (P < 0.05). The IL-6 and PGE2 in the Ti/VIVIT group were significantly lower than that in the Ti group (P < 0.05). Conclusions 11R-VIVIT peptide specific blockade of Cn/NFAT signaling pathway significantly inhibited IL-6 and PGE2 of osteoblast cells induced by titanium particles.
