[Risk Factor Analysis of Abdominal Aortic Enlargement after Thoracic Endovascular Aortic Repair Using Two-Stent Graft Implantation for Stanford Type B Aortic Dissection].

Objective: To explore the risk factors of abdominal aortic enlargement (AAE) after thoracic endovascular aortic repair using two-stent graft implantation (TEVAR-TSI) for Stanford type B aortic dissection.

Methods: The clinical and imaging data of patients who underwent TEVAR-TSI for Stanford type B aortic dissection in the First Affiliated Hospital of Hebei North University from January 2013 through September 2020 were retrospectively collected and analyzed. CT angiography (CTA) scans were performed before the procedure.

[The Characteristics of Aortic Remodeling after Thoracic Endovascular Aortic Repair using Two-stent Graft Implantation for Stanford Type B Aortic Dissection].

Objective: To investigate the characteristics of aortic remodeling after thoracic endovascular aortic repair using two-stent graft implantation (TEVAR-TSI) for Stanford B aortic dissection.

Methods: The clinical and imaging data of 128 patients who underwent TEVAR-TSI for Stanford B aortic dissection in the First Affiliated Hospital of Hebei North University from January 2013 through May 2019 were retrospectively collected. CT images were obtained before (T ) TEVAR-TSI and, 1 week (T ), 3 months (T ), 6 months (T ), 1 year (T ) after TEVAR-TSI.

Propranolol combined with dopamine has a synergistic action in intensifying and prolonging cutaneous analgesia in rats.

Background: The purpose of the experiment was to assess interactions of dopamine with propranolol as an infiltrative anesthetic.

Methods: After injecting the rats with four doses of drugs subcutaneously, the cutaneous analgesic effect of propranolol was compared with dopamine through the blockade of cutaneous trunci muscle reflex (CTMR) in response to local skin pinprick. Drug-drug interactions were examined via an isobolographic analysis.

[Effects of butylphthalide on the apoptosis of PC-12 cells under the induction of β-amyloid peptide].

Objective: To study the protective effects of butylphthalide (NBP) on the Aβ(25-35)-induced apoptosis in PC-12 cells.

Methods: The apoptosis of PC-12 cell was analyzed by MTT assay, transmission electron microscope and PI method at different concentrations of NBP (0.1, 1.
