The immune system has been reported to suppress the development and progression of neoplastic lesions; however, the exact mechanisms by which neoplastic lesions and the immune system interact are not well understood. Within the last decade, tiny membrane bound particles, approximately 30-100 nm in diameter, have been observed in the blood and other body(More)
Although social and cultural influences are clearly important, family, twin and adoption studies indicate that genes contribute significantly to substance abuse.1–3 Substance abuse is associated with novelty seeking, a heritable human personality trait which may be influenced by alleles of the dopamine D4 (DRD4) gene exon III VNTR.4,5 Consequently Kotler et(More)
Statins are the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors that function as potent inhibitors of cholesterol biosynthesis and have been used for many years for the treatment of hypercholesterolemia. However, accumulating experimental and clinical studies have revealed that the health benefits associated with statins treatment, particularly(More)
OBJECTIVE To investigate the changes about nitric oxide(NO), endothelin(ET) derived from alveolar macrophages(AMs) and the effects of nitroglycerin(NTG) and mexamethason(DXM) on ET and NO in patients with mild and middle asthma. METHODS The AMs from 7 healthy control subjects and 15 patients with attacking asthma were purified, and divided into healthy(More)
BACKGROUND It has been widely demonstrated that endothelial progenitor cells are involved in several diseases and that they have therapeutic implications. In order to define the altered pulmonary vascular homeostasis in chronic obstructive pulmonary disease, we sought to observe the level and functions of circulating endothelial progenitor cells in patients(More)
This study evaluated the effectiveness of silk fibroin materials for wound repair confined to the buccal mucosa in a rat model by assessing several key clinical parameters and the associated local and systemic immune response. Ninety male SD rats were subjected to microscopic oral surgery to establish a full thickness wound on the buccal mucosa. Rats were(More)
Detrimental health effects of atmospheric exposure to ambient particulate matter (PM) have been investigated in numerous studies. Exposure to pollutional haze, the carrier of air pollutants such as PM and nitrogen dioxide (NO2) has been linked to lung and cardiovascular disease, resulting increases in both hospital admissions and mortality. This review(More)
OBJECTIVE To investigate the characteristics of bacteriology and the drug resistance in the patients with chronic obstructive disease (COPD) combined with pneumonia at our respiratory intensive care unit(RICU) in 2001. METHODS The sputum of 543 patients with COPD combined with pneumonia was collected with a regular method, the bacteria were cultured, and(More)
In traditional Chinese medicine, arsenous compounds, including arsenic trioxide (ATO), are often used to treat many diseases, which are safe and effective. Recently, studies have indicated that Th17- IL-17 involved in the pathogenesis and development of asthma. The goal of this study was to investigate the effect and mechanism of ATO on asthma, especially(More)
A theory of photon-assisted impact ionization in solids is presented. Our theory makes a quantum description of the new impact ionization-cold avalanche ionization recently reported by P. P. Rajeev, M. Gertsvolf, P. B. Corkum, and D. M. Rayner [Phys. Rev. Lett. 102, 083001 (2009)]. The present theory agrees with the experiments and can be reduced to the(More)
