infection in a patient with pulmonary sequestration: A case report.

Background: () infection is uncommon in clinical practice. Pulmonary sequestration complicated with has not been reported in the literature. Here, we present a case of pulmonary se-questration complicated with infection in an immunocom-petent woman.

High frequency jet ventilation at the distal end of tracheostenosis during flexible bronchoscopic resection of large intratracheal tumor: Case series.

Introduction: Resection of a large intratracheal tumor with severe obstruction via flexible bronchoscope remains a formidable challenge to anesthesiologists. Many artificial airways positioned proximal to tracheal obstruction can not ensure adequate oxygen supply. How to ensure effective gas exchange is crucial to the anesthetic management.

Retropharyngeal abscess presenting as acute airway obstruction in a 66-year-old woman: A case report.

Background: Adult retropharyngeal abscess (RPA) is extremely rare, and most cases reported in the literature were related to tuberculous infection. We present a case of RPA with acute airway obstruction as the main manifestation in a 66-year-old woman that was considered to be non-tubercular suppurative inflammation in the retropharyngeal space.

Case Summary: A 66-year-old woman complaining of chills and fever was admitted to our hospital.

Bacterial etiology in early re-admission patients with acute exacerbation of chronic obstructive pulmonary disease.

Background: Repeatedly hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) are often exposed to more antibiotics, but the distribution of pathogenic bacteria in these patients is poorly understood. The objectives of this study were to analyze the distribution of pathogenic bacteria and the risk factors associated with multidrug-resistant (MDR) bacteria infection in early re-admission patients with AECOPD.

Methods: We retrospectively reviewed charts for patients with AECOPD admitted to our hospital between January 2011 and November 2012.

Relationship between Fractional Exhaled Nitric Oxide Level and Efficacy of Inhaled Corticosteroid in Asthma-COPD Overlap Syndrome Patients with Different Disease Severity.

This study explored the relationship between the fractional exhaled nitric oxide (FeNO) level and the efficacy of inhaled corticosteroid (ICS) in asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) patients with different disease severity. A total of 127 ACOS patients with ACOS (case group) and 131 healthy people (control group) were enrolled in this study. Based on the severity of COPD, the ACOS patients were divided into: mild ACOS; moderate ACOS; severe ACOS; and extremely severe ACOS groups.

A rare fatal case of a novel bunyavirus-associated hemophagocytic lymphohistiocytosis.

Herein we describe a rare fatal case of a novel bunyavirus-associated hemophagocytic lymphohistiocytosis (HLH) in a 62-year-old female patient. The novel bunyavirus infects patients with or without HLH who have similar clinical features such as fever, thrombocytopenia, and leukocytopenia. Therefore, the diagnosis of HLH can be easily missed.

[Association between human beta defensin-1 single nucleotide polymorphisms and susceptibility to pulmonary tuberculosis].

Objective: To investigate the possible association between the SNP in the 5' untranslated region (5' UTR) of the human beta defensin 1 (DEFB1) gene and the susceptibility to pulmonary tuberculosis (PTB) in Chinese Han population.

Methods: In this case-control study, venous blood was collected from 102 patients with PTB and 148 healthful persons. Genomic DNA was extracted using whole blood DNA extraction kit.

[Changes of adrenomedullin 2/intermedin in the lung of rats with chronic hypoxic pulmonary hypertension].

Aim: To investigate the changes and probable roles of adrenomedullin2/intermedin (AIDM2/IMD), a novel micromolecular bioactive peptide, in the lungs of rats with chronic hypoxic pulmonary hypertension.

Methods: Twenty male SD rats were randomly divided into normal control group (NC) and normobaric hypoxia group (4H). The protein levels of ADM and ADM2/IMD) in the plasma and lung were measured by radioimmunoassay and immunohistochemistry.

[Effects and relationship between NO and HIF-1alpha in rats with pulmonary hypertension induced by hypoxia].

Aim: To investigate the expression of hypoxia-inducible factor-1 alpha (HIF-1alpha) in rats with chronic pulmonary hypertension induced by hypoxia and hypercapnia and its relationship with nitric oxide(NO).

Methods: Fourty male Sprague-Dawley rats were randomly divided into four groups, normal control group (NC), hypoxia-hypercapnia group (HH), hypoxia - hypercapnia + L-arginine liposome group(HP) and hypoxia-hypercapnia+ N-nitro-L-arginine methylester group (HM). Colorimetric analysis, immunohistochemistry and in situ hybridization were used for detection of NO, HIF-1alpha and constitutive nitric oxide synthase (ecNOS).

[Expression of Urotensin II and its receptor on right ventricle in rats of pulmonary hypertension].

Aim: To observe the expression of Urotensin II (U II) and its receptor (UT) on right ventricle in rats with chronic pulmonary hypertension induced by hypoxia and hypercapnia.

Methods: Twenty male SD rats were randomly divided into normal control group (NC) and hypoxia-hypercapnia 4-week group(HH). Mean pulmonary arterial pressure(MPAP) and the weight ratio of right ventricle (RV) to left ventricle plus septum (LV+ S) were calculated separately.

[Dynamic changes of urotensin II receptor in pulmonary artery and arterioles of rats chronically exposed to hypoxia-hypercapnia].

Aim: To investigate the dynamic changes and functions of urotensin II (U lI) receptor (UT) in pulmonary arteries of rats chronically exposed to hypoxia-hypercapnia.

Methods: In rats with hypoxia-hypercapnia at 1, 2 and 4 weeks U II receptor binding of pulmonary arteries sarcolemma was determined by radioligand assay. U II mRNA and UTmRNA in various grades of pulmonary arterioles were measured by in situ hybridization.
