The Protective Effects of Helicobacter pylori Infection on Allergic Asthma.

As an ancient Gram-negative bacterium, Helicobacter pylori has settled in human stomach. Eradicating H. pylori increases the morbidities of asthma and other allergic diseases.

Clear cell tumor of the lung: a retrospective analysis.

Background: There have been no clinical reports on clear cell tumor of the lung (CCTL) based on large studies or epidemiological surveys in the literature. The purpose of this study was to provide a retrospective analysis of CCTL patients in China by reviewing the clinical data of reported CCTL cases.

Methods: The China academic journals full-text database search engines were used to collect the related cases from January 1979 to June 2011.

[Clear cell tumor of the lung: report of seven cases and literature review].

Objective: To study the clinical characteristics, chest imaging, pathology, diagnosis and treatment of clear cell tumor of the lung (CCTL).

Methods: Seven cases of CCTL diagnosed from January 2000 to December 2010 in our hospital, and 38 cases from literatures published in mainland of China, were retrospectively analyzed.

Results: The age of the patients was (44 ± 18) years, with equal sex distribution.

An unusual case of Welder's siderosis with local massive fibrosis: a case report.

Welder's siderosis was traditionally described as "benign pneumoconiosis" because of the absence of associated symptoms, functional impairment or pulmonary fibrosis. Although several authors have reported evidence of fibrosis in the lungs of welders, siderosis with local massive fibrosis has been rarely described. In this paper, we present a case of Welder's siderosis with local massive fibrosis mimicking lung cancer.

[The in vitro and in vivo effects of adenovirus-mediated inhibitor of growth 4 and interleukin-24 co-expression on the radiosensitivity of human lung adenocarcinoma].

Objective: To study the radiosensitivity of the recombinant adenoviral vector (called Ad-ING4-IL-24) carrying and co-expressing inhibitor of growth 4 (ING4) and interleukin-24 (IL-24) to human lung adenocarcinoma and the underlying mechanisms.

Methods: The expression levels of ING4 and IL-24 were detected by Western blot. The growth-suppressing and apoptosis-inducing effect of Ad-ING4-IL-24 combined with radiotherapy on SPC-A-1 lung carcinoma cells were assessed by MTT assay and FCM respectively.

Angiosarcoma of the lung: 2 cases report and literature reviewed.

Angiosarcoma is a kind of malignant tumors derived from vascular endothelial cell. Its incidence rate is very low. Pulmonary angiosarcomas are usually secondary tumors, and primary cases are less than 20 so far.

N'-(3,5-Dichloro-2-hydroxy-benzyl-idene)-3-methoxy-benzohydrazide methanol solvate.

In the title compound, C(15)H(12)Cl(2)N(2)O(3)·CH(3)OH, the Schiff base mol-ecule is nearly planar, with a dihedral angle of 4.5 (2)° between the two benzene rings. An intra-molecular O-H⋯N hydrogen bond is observed.

[Combined effects of endostatin gene transfer and ionizing radiation on lung adenocarcinoma model of A549-cells].

Objective: The combined inhibition effects of endostatin gene transfer and ionizing radiation on lung adenocarcinoma model of A549-cell were investigated.

Methods: Human endostatin gene was transferred into lung adenocarcinoma A549 cell by retrovirus-mediation to obtain an A549/Endo cell. A549 and A549/Endo cells were xenoimplanted in nude mice respectively (each group included 10 mice).
