AIM:To observe the effects of cornus iridoid glycosides(CIG)on inflammatory reaction especially the inflammatory cytokines in the brain after traumatic brain injury,and to explore the possible mechanisms of its neuroprotective effect.METHODS:SD rats were intragastrically administered with different doses of CIG(30,60 and 120 mg?kg-1?d-1)for 7 d.The traumatic brain injury rat model was induced by improved Feeney's fall weight method,and the brains were taken out 24 h and 72 h after brain injury,respectively.The morphological changes were observed by HE staining in the cerebral cortex.The expressions of inflammatory cytokine tumor necrosis factor-?(TNF-?)and interleukin-1?(IL-1?)were detected by immunohistochemical method.The image processing and statistical analysis were used to measure the number and the area of immunoreactive cells.RESULTS:HE staining showed the pathological changes were serious in the cerebral cortex of model group,and compared with the model group,the pathological changes were obviously reduced in CIG group.The positive immunoreactive cells of TNF-? and IL-1? were mainly distributed around the foci of contusion,the expressions of TNF-? and IL-1? in the model group were significantly higher than those in sham operated group,and the high expressions were sustained from 24 h to 72 h after brain injury.Compared with the model group,the levels of TNF-? and IL-1? in the brain of CIG treatment groups were obviously decreased in a dose-dependent manner and the inhibitory effects of TNF-? and IL-1? were more significant at 72 h after brain injury.CONCLUSION:CIG may have neuroprotective effect on traumatic brain injury through inhibiting the expression of inflammatory cytokines and reducing the inflammatory reaction.

Background and purpose:Thyroglobulin antibody (TgAb) is often positive in papillary thyroid carcinoma (PTC) patients. This study aimed to investigate the effect of TgAb on radioiodine ablation efficacy in PTC patients.Methods:A total number of 329 PTC patients with no distant metastasis were included and classified into 2 groups[G1 group (>115 U/mL,n=84) and G2 group (<115 U/mL,n=245)], G2 group was further divided into 2 subgroups[S1 (>40 U/mL,n=31) and S2 (<40 U/mL,n=214)], before131I ablation. The median follow-up time was 24 months after a total or subtotal thyroidectomy and subsequent131I ablation. The efficacy in terms of131I ablation success rates (IBR) between two groups were compared and the influencing factors were analyzed according to criteria posed by 2015 American Thyroid Association Guidelines, then the effect of131I dose on IBR was also explored.Results:Female and younger age were more prevalent in patients with high TgAb (P<0.05). The G1 group presented lower IBR over the G2 group (35.7%vs 72.7%,P=0.000). Moreover, S1 group also presented lower IBR over S2 group (54.8%vs 75.2%,P=0.017), indicating the adverse effect from high titer TgAb on IBR. No matter high or low dose, the G1 group presented lower IBR (34.1%vs 71.9%, 37.2%vs 73.2%;P=0.000). However, IBR did not differ in G1 or G2 group either with high or low dose131I (P>0.05). TgAb was the only adverse indicator correlating with IBR in multi-logistic regression analysis (P=0.018).Conclusion:TgAb could negatively affect131I ablation efficacy, while increasing the dose of131I failed to improve the success rate in such cases.
