ABSTRACT
Objective@#To observe the changes of liver metabolism in mice exposed to artificial light at night. @*Methods@#Healthy male C57BL/6J mice were randomly divided into the light at night group and the control group, with 8 mice in each group. The daily light/dark cycle was 12/12 hours in the control group, and 24/0 hours in the light at night group for 10 consecutive days. The hepatic metabolite profiles of the two groups of mice were detected by high performance liquid chromatography tandem mass spectrometry. The modelling was assessed by combining principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis ( OPLS-DA ) , The changes of metabolites in the two groups were compared through KEGG database.@*Results@#Compared with the control group, 9 different metabolites were detected in the light at night group, among which the down-regulated metabolites were glycine-betaine, glutathione, tyrosine, betaine, lysine, hypoxanthine, histidine and methionine, and the up-regulated ones were mannose-6-phosphate. The weight analysis of the metabolic pathways showed that the major influences on liver of light at night group were phenylalanine-tyrosine-tryptophan metabolism, tyrosine metabolism, fructose and mannose metabolism, cysteine and methionine metabolism and histidine metabolism. @*Conclusion@#The metabolism of various amino acids and sugars in light at night mice is disturbed,and the key differential metabolites are tyrosine, methionine, histidine and mannose-6-phosphate.
ABSTRACT
Objective To explore the efficacy and safety of Solitaire stents and the multi-mode vascular recanalization in the treatment of acute cerebral infarction. Methods Twenty-two patients with acute cerebral infarction, who were treated by Solitaire stents and the multi-mode vascular recanalization (research group) in our hospital from November 2014 to February 2017, were included in this study. Among them, 16 cases were combined with balloon dilation after arterial thrombosis, 4 cases were given stent implantation (3 cases were given Solitair stent and 1 case was given Apollo stent), and 2 cases were given arterial catheter directed thrombolysis. Eighteen patients with acute cerebral infarction who were treated only by Solitaire stent artery occlusion from October 2011 to October 2014 were used as control group. Data of the onset to the vagina vasorum time, the onset to the recanalization time, the revascularization of interventional therapy, the NIHSS scores at admission and discharge, mRS score after 90-day treatment, incidence rate and the mortality were compared between two groups. Results There were no significant differences in the durations from onset to the vagina vasorum and from the onset to the recanalization between the two groups. The recanalization was better in research group than that of control group (P<0.05). There were no significant differences in scores of NIHSS at hospital discharge and admission between two groups. The near-term treatment efficacy was similar in two groups. However, mRS score was significantly lower in the research group than that in control group after 90-day treatment (P<0.05). There were no significant differences in the symptomatic intracranial hemorrhage, high perfusion encephalopathy, the incidence rate and the mortality rate of the complications related to the operation between two groups of patients. Conclusion Solitaire stents and the multi-mode vascular recanalization can significantly improve the revascularization, the further clinical prognosis and the quality of survival in patients with acute cerebral infarction, which are safe and efficacy without increasing incidence rate and mortality rate of complications.
