The feasibility of 1-stop examination of coronary CT angiography and abdominal enhanced CT.

This study aims to evaluate the feasibility of performing coronary computed tomography angiography (CCTA) and abdominal enhanced computed tomography (CT) with 1-time injection of the agent.CCTA images (right coronary artery, left anterior descending coronary artery, and left circumflex coronary artery) were collected from 20 patients who completed a 1-stop combined examination of CCTA and abdominal enhanced CT (group A), 20 patients who only underwent abdominal enhanced CT (group B1), and 20 patients who only underwent CCTA (group B2). These images were interpreted using the 5-point Likert scale system by 2 experienced radiologists, and abdominal images were observed for breathing artifact.

[Serum proteomic analysis of cicatricial airway stenosis].

Objective: To establish serum protein fingerprint profile in patients with cicatricial airway stenosis and compared with healthy control.

Methods: Serum samples of 17 cicatricial airway stenosis patients and 17 healthy persons were analyzed by SELDI-TOF-MS to select the differently expressed proteins through Biomarker Wizard software.

Results: Compared with healthy control, 49 protein biomarkers were identified.

[The pilot study of the effect of paclitaxel by local application on scar formation after airway injury in rabbits].

Objective: To investigate the effect of local application of paclitaxel on airway scar formation after airway injury in rabbits.

Methods: Forty New Zealand rabbits were randomly divided into four groups, negative control group (n = 10), saline control group (n = 10), group I (n = 10), group II (n = 10). All rabbits received tracheotomy.

Molecular cloning and expression of IL2 cDNA from the Tibet pig.

Interleukin-2 is a vital cytokine secreted by activated T lymphocytes, and plays important role in the regulation of cellular and humoral immunity of animals. In our experiment, IL2 cDNA of the Tibet Pig was first cloned by RT-PCR from ConA-stimulated lymphocytes in the blood and subcloned into pMD-18 T vector, which then was identified with endonuclease restriction. The sequencing result showed that Tibet pig IL-2 (TPIL-2) cDNA was 503 bp long (ORF was 465 bp) (Genbank accession number: AY 294018).
