In-hospital efficacy of endovascular aortic repair in patients with impending rupture versus contained rupture of abdominal aortic aneurysms.

Background: The purpose of our study was to compare the efficacy of endovascular aortic repair (EVAR) in patients with impending rupture of abdominal aortic aneurysm (IRAAA) versus contained rupture of abdominal aortic aneurysm (CRAAA).

Methods: Of the 21 patients who underwent EVAR for infrarenal AAA from January 2009 to May 2011, 11 did so for IRAAA and 10 for CRAAA. We compared their demographic and aneurysmal characteristics, comorbidities, complications, and clinical outcomes during hospitalization.

A retrospective study on endovascular management of iatrogenic vascular injuries.

The purpose of this study was to evaluate the outcome of endovascular management of iatrogenic vascular injuries (IVIs). We retrospectively reviewed the clinical records of 19 consecutive patients who underwent endovascular therapy of IVIs. Endograft implantation was conducted in 13 patients, intravascular embolization using coil was performed in four patients, combined treatment involving endovascular balloon intervention and percutaneous thrombin injection was done in one patient and the remaining one patient received balloon compression for hemostasis.

Hybrid endovascular repair in aortic arch pathologies: a retrospective study.

The aortic arch presents specific challenges to endovascular repair. Hybrid repair is increasingly evolving as an alternative option for selected patients, and promising initial results have been reported. The aim of this study was to introduce our experiences and evaluate mid-term results of supra aortic transpositions for extended endovascular repair of aortic arch pathologies.

[A preliminary report of SARS coronavirus specific RNA in SARS convalescents and medical person].

Objective: To observe the method of fluorescent-polymerase chain reaction (F-PCR) and gene-hip technique in detecting coronavirus in severe acute respiratory syndrome (SARS) and its value for clinical application.

Methods: Serum of 60 SARS patients, 20 samples of serum and 20 samples of gargling fluid of medical staff of the "Fever Clinic", and one cDNA specimen obtained from one SARS suspect patient were examined with F-PCR diagnosis kit and gene-chip technique for SARS coronavirus.

Results: Three methods, including DR Chip and two F-PCR kit from Zhongshan College Da'an gene stock company and Shanghai Fortune industrial joint-stock Co, Ltd, were used, and the results were all negative for all specimens, except one cDNA specimen, which was obtained from one SARS suspect patient, virus could be amplified by F-PCR.

[Comparison of serum biochemical features between SARS and other viral pneumonias].

Objective: To identify blood chemistry changes in coronavirus of severe acute respiratory syndrome (SARS).

Methods: Biochemical changes in SARS patients were summarized and compared with other viral pneumonias. Serum total protein (TP), albumin (Alb), total cholesterol (TC), triglyceride (TG), calcium (Ca), ferrum (Fe), lactate dehydrogenase (LDH), creatine kinase (CK), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) between SARS and other viral pneumonias were examined by Roche Diagnostics assay, HITACHI7600 automatic analyzer.

Effects of free radicals and amyloid beta protein on the currents of expressed rat receptors in Xenopus oocytes.

Objective: To investigate the effects of free radicals (FRs) and amyloid beta protein 1-40 (A beta 1-40) on the functions of expressed neurotransmitter receptors (NRs) in Xenopus oocytes.

Methods: Total RNA and messenger RNA (mRNA) was prepared from 3-month-old Wistar rat brain tissues with Promega kits and microinjected into maturated Xenopus oocytes (stages V-VI) with 50 nl (50 ng) for each oocyte. The microinjected oocytes were incubated with modified Bath's solution at 19.

[Effects of free radicals and amyloid beta protein on the currents of expressed rat receptors in Xenopus oocytes].

Aim: To investigate the effects of free radicals (FRs) and amyloid beta protein (A beta 1-40) on the functions of expressed neurotransmitter receptors (NRs) from rat brains in Xenopus oocytes.

Methods: Total RNA and Messenger RNA (mRNA) was prepared from 3-month-old Wistar rat brain tissues with Promega kits and microinjected into mature Xenopus oocytes (stage V - VI) with 50 nl (50 ng) for each oocyte for receptor expression and their currents were recorded with double electrode voltage clamp technique. Superoxide anion free radicals (SAFRs) and A beta 1-40 was added 12 h, 24 h, 96 h to incubation solution before recording.
