The overall health condition of patients significantly affects the diagnosis, treatment, and prognosis of endodontic diseases. Asystemic consideration of the patient’s overall health along with oral conditions holds the utmost importance in determining thenecessity and feasibility of endodontic therapy, as well as selecting appropriate therapeutic approaches. This expert consensus is acollaborative effort by specialists from endodontics and clinical physicians across the nation based on the current clinical evidence,aiming to provide general guidance on clinical procedures, improve patient safety and enhance clinical outcomes of endodontictherapy in patients with compromised overall health.

Background and purpose To evaluate relationship between fluid-attenuated inversion recovery vascular hyperintensity(FVH)after intravenous thrombolysis and outcomes in different lesion patterns on diffusion-weighted imaging(DWI).Methods Patients with severe internal carotid or intracranial artery stenosis who received intravenous thrombolysis from March 2012 to April 2019 were *** were divided into four groups by DWI lesion patterns:border-zone infarct(BZ group),multiple lesions infarct(ML group),large territory infarct(LT group),and single cortical or subcortical lesion infarct(SL group).Logistic regression was performed to identify risk factors for outcome(unfavourable outcome,modified Rankin Scale(mRS)≥2;poor outcome,mRS≥3).Results Finally,203 participants(63.3±10.2 years old;BZ group,n=72;ML group,n=64;LT group,n=37;SL group,n=30)from 1190 patient cohorts were *** adjusting for confounding factors,FVH(+)was associated with unfavourable outcome in total group(OR 3.02;95%CI 1.49 to 6.13;p=0.002),BZ group(OR 4.22;95%CI 1.25 to 14.25;p=0.021)and ML group(OR 5.44;95%CI 1.41 to 20.92;p=0.014)***(+)was associated with poor outcome in total group(OR 2.25;95%CI 1.01 to 4.97;p=0.046),BZ group(OR 5.52;95%CI 0.98 to 31.07;p=0.053)and ML group(OR 4.09;95%CI 1.04 to 16.16;p=0.045)patients,which was marginal ***(+)was not associated with unfavourable or poor outcome in LT and SL *** This study suggests that association between FVH and outcome varies with different lesion patterns on *** presence of FVH after intravenous thrombolysis may help to identify patients who require close observations in the hospitalisation in patients with border-zone and multiple lesion infarcts.

In this paper, we are interested in investigating the causal relationships among futures sugar prices in the Zhengzhou futures exchange market （ZF）, the spot sugar prices in Zhengzhou （ZS） and the futures sugar prices in New York futures exchange market （NF）. A useful tool called Bayesian network is introduced to analyze the problem. Since there are only three variables in our Bayesian network, the algorithm is straightforward： we display all the 25 possible network structures and adopt certain scoring metrics to evaluate them. We applied five different scoring metrics in total. Firstly, for each metric, we obtained 24 scores, each calculated from one of the 24 possible structures i.e. a Directed Acyclic Graph （DAG）. Then we eliminated the network structure which represents the independence of the three variables according to our prior knowledge concerning the futures sugar market. After that, the optimal network structure which implies the causal relationships was selected according to the corresponding scoring metric. Finally, after comparing the results from different scoring metrics, we obtained the relatively affirmative conclusion that ZS causes ZF from both the Bayesian Dirichlet （BD） metric, Bayesian Dirichlet-Akaike Information Criterion （BD-AIC） metric, Bayesian Dirichlet-Bayesian Information Criterion （BD-BIC） metric and Bayesian Information Criterion （BIC） metric. The conclusions that NF causes ZF and ZF causes ZS from the Akaike Information Criterion （AIC） metric and ZF causes ZS from the BIC metric were useful and significant to our investigation.
