Objective:To investigate effect of blood glucose on early neurological deterioration (END) and outcome after intravenous thrombolysis in patients with acute ischemic stroke (AIS).Methods:Patients with AIS treated with intravenous thrombolysis in the Department of Neurology, the Second Affiliated Hospital of Xuzhou Medical University from June 2020 to December 2021 were collected retrospectively. Demographic and baseline clinical data of the patients were collected. END was defined as an increase of ≥2 in reassessing the maximum score of the National Institutes of Health Stroke Scale within 72 h after admission compared with the baseline. Poor outcome was defined as the modified Rankin Scale score ≥3 at 3 months after onset. Multivariate logistic regression analysis was used to evaluate the independent correlation between various blood glucose indicators (including admission blood glucose [ABG], admission hyperglycemia [AH], fasting blood glucose [FBG] on the next day after admission, and stress hyperglycemia ratio [SHR]) and END and poor outcome after intravenous thrombolysis. Results:A total of 319 patients with AIS were enrolled, including 126 (39.5%) had AH, 67 (21.0%) had END, and 85 (26.6%) had poor outcomes at 3 months after onset. Multivariate logistic regression analysis showed that after adjusting for confounding factors, ABG (odds ratio [ OR] 1.188, 95% confidence interval [ CI] 1.105-1.278; P<0.001), AH ( OR 4.246, 95% CI 2.291-7.869; P<0.001), FBG ( OR 1.272, 95% CI 1.139-1.420; P<0.001), and SHR ( OR 2.559, 95% CI 1.192-5.664; P=0.016) were independently associated with END, while all blood glucose indicators were not independently associated with the poor outcomes at 3 months after onset. Conclusion:Higher blood glucose is independently associated with END after intravenous thrombolysis in patients with AIS, but not with the outcomes at 3 months after onset.

Objective To analyze the curriculum status of dental nursing education program in China , in order to improve the dental nursing program in higher vocational education .Methods Two dental nursing program in higher vocational college were selected , to analyze the specialty-oriented courses and the implementation .Results The dental nursing specialty-oriented courses differ in the two programs , a lower proportion of the specialty-oriented courses , and lack of course on basic science of stomatology were shown . Conclusions We should integrate the curricular resources , increase the class hours about dental nursing , and add courses on basic science of stomatology and nursing of oral and maxillofacial surgery .

OBJECTIVE To study the vasorelaxant effects and mechanism of polyphenol compound 2,4′,5′-trihydroxy-5,2′- dibromo-diphenyl-methanone(LM49)on isolated aortic rings of rats. METHODS Thoracic aortic vascular rings of rats were collected. Using the diastolic rate as index , the effects of different concentrations of LM 49 on endothelium-intact and endothelium-denuded aortic rings pre-contracted by norepinephrine (NE,1×10-6 mol/L)or KCl (60 mmol/L)were investigated. After pre-culturing vascular rings by nitric oxide synthase inhibitor L-nitro-arginine methyl ester (L-NAME,0.1 mmol/L) and cyclooxygenase inhibitor indomethacin (1×10-5 mol/L),as well as pre-culturing vascular rings by 4 potassium channel blockers [BaCl 2(0.1 mmol/L),tetraethylammonium(TEA,5 mmol/L),4-aminopyridine(4-AP,0.1 mmol/L)and glibenclamide (1×10-5 mol/L)],the vasorelaxant effect of different concentrations of LM 49 on the vascular rings were investigated by using the same method. With the percentage of vasoconstriction as the index ,using KCl (60 mmol/L),NE(1×10-6 mol/L),calcium channel blocker verapamil (1×10-6 mol/L)and sarcoplasmic Δ 基金项目 重大新药创制国家科技重大专项 (No.2018ZX097- reticulum Ca 2 +-adenosine triphosphate (ATP) enzyme pump inhibitor thacarotene (TG,1×10-6 mol/L)to induce the release of calcium in vascular rings in the absence of calcium. CaCl was added cumulatively ,and the effect of LM 49 on the cxyw06,vasoconstriction caused by calcium influx induced by CaCl 2 was investigated. RESULTS 3×10-6,5×10-6,1×10-5 mol/L LM49 had a significant relaxation effect on NE and KCl precontracted vascular rings (P<0.01); whether the endothelium was removed or not had no significant effect on the vasodilation of LM 49(P>0.05). After L-NAME ,indomethacin, TEA and 4-AP was pre-incubated ,different concentrations of LM 49 had no significant effects on aortic rings precontracted by NE (P>0.05). Glibenclamide and BaCl 2 could inhibit the vasorelaxant effects of LM 49 on aortic rings precontracted by NE (P<0.01). In the absence of calcium ,LM49 could inhibit the contraction caused by calcium influx induced by accumulated CaCl 2 after pre-incubation with KCl ,NE,verapamil and TG (P<0.01). CONCLUSIONS LM49 evokes significant relaxation of isolated aortic vascular rings without endothelium dependence ;the mechanism of which is inducing ATP-sensitive potassium channel , inward rectifier potassium channel open and restraining extracellular Ca 2 + influx via voltage-gated calcium channel , receptor-operated calcium channel and store-operated calcium channel.
