PURPOSE To investigate the associations between plasma miR-34b/c expression levels and osteosarcoma (OS). SUBJECTS AND METHODS A case-control study was conducted in 133 patients with OS and 133 controls. MiR-34b/c levels were detected by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) assays. Genotyping of SNP rs4938723 was done(More)
OBJECTIVE The aim of this study was to investigate whether velocity vector imaging (VVI) combined with stress echocardiography could detect potential diffused myocardial impairment of the left ventricle (LV) in diabetic rats. METHODS Thirty-five male SD rats were randomly divided into either the control group or the diabetes mellitus (DM) group (induced(More)
During the winter of 1988-1989, parents of 2,789 elementary-school students completed standardized questionnaires. The students were 5-14 y of age and were from three urban districts and one suburban district of three large Chinese cities. The 4-y average ambient levels of total suspended particles in the three cities differed greatly during the period(More)
Electroconvulsive therapy has been commonly applied in the treatment of refractory depression, but its cognitive side effects are noticed and restrict its application. The molecular mechanisms underlying the side effects remain elusive, and there is no efficient prevention. By employing a recognized electroconvulsive shock (ECS) rat model, we found in the(More)
We developed algorithms for spatial scaling of leaf area index (LAI) using sub-pixel information. The study area is located near Liping County, Guizhou Province, in China. Methods for LAI spatial scaling were investigated on LAI images with 960 m resolution derived in two ways. LAI from distributed calculation (LAID) was derived using Landsat ETM+ data (30(More)
MicroRNA-17-92 (miR-17-92) cluster has been demonstrated to play a crucial role in various human cancers. However, its effects in osteosarcoma have not yet been elucidated. The purpose of this study was to investigate the clinical significance of miR-17-92 cluster in osteosarcoma. MiR-17-92 cluster expression in osteosarcoma clinical samples and cell lines(More)
This article serves as an introduction to this special issue, "China's Forest Carbon Sequestration", representing major results of a project sponsored by the Canadian International Development Agency and the Chinese Academy of Sciences. China occupies a pivotal position globally as a principle emitter of carbon dioxide, as host to some of the world's(More)
OBJECTIVE To investigate clinical features and ultrasound findings in cases of placental site trophoblastic tumor (PSTT). METHODS Fourteen cases of PSTT treated at our institution between May 2004 and October 2010 were identified and the clinical features and findings on transvaginal sonography (TVS) were investigated. Pathological confirmation of PSTT(More)
ETHNOPHARMACOLOGICAL RELEVANCE The flowers of Gentiana veitchiorum has been widely used in decoction form in the traditional medicine of Tibet against tussis, tracheitis, angina for their anti-inflammatory, antimicrobial and alexipharmic properties. AIM OF THE STUDY The aim of current study was to evaluate the therapeutic effects of Feining, a Chinese(More)
Human adrenomedullin (hADM) is a newly isolated peptide with hypotensive activity in normotensive rats. The objective of this study was to investigate the effect of hADM(13-52) on hypertensive animals. hADM(13-52) induced a dose-dependent decrease in the blood pressure of spontaneously hypertensive rats and renal hypertensive rats. This result suggests that(More)
