Rosids are a major clade in the angiosperms containing 13 orders and about one-third of angiosperm species. Recent molecular analyses recognized two major groups (i.e., fabids with seven orders and malvids with three orders). However, phylogenetic relationships within the two groups and among fabids, malvids, and potentially basal rosids including(More)
BACKGROUND Comprehensive health economic evaluation, a key component of the Cancer Screening Program in Urban China (CanSPUC), was expected to support government policy-making on screening initiatives for common cancers (lung, breast, colorectal, oesophageal, liver, and stomach cancer) in urban China. Estimation of expenditure for cancer diagnosis and(More)
OBJECTIVE To study and compare the effect of neutrophil elastase inhibitors (GW311616A and sivelestat) on the proliferation and apoptosis of U937 cells. METHODS Inhibitory effects of GW311616A and sivelestat on the proliferation of U937 cells were assayed by MTT assay. The morphologic changes of U937 cells were detected by transmission electron(More)
BACKGROUND Esophageal cancer is associated with substantial disease burden in China, and data on the economic burden are fundamental for setting priorities in cancer interventions. The medical expenditure for the diagnosis and treatment of esophageal cancer in China has not been fully quantified. This study aimed to examine the medical expenditure of(More)
In the majority of acute promyelocytic leukemia (APL) cases, translocons produce a promyelocytic leukemia protein-retinoic acid receptor α (PML-RARα) fusion gene. Studies have reported that neutrophil elastase (NE) cleaves bcr-1-derived PML-RAα in early myeloid cells, leaving only the nuclear localization signal (NLS) of PML attached to RARα. NLS-RARα(More)
A BF3·OEt2-AgSCF3 mediated direct trifluoromethylthiolation/cascade cyclization of propynols involving the SCF3 anion nucleophilic pathway is developed. This protocol also provides an opportunity to construct valuable trifluoromethylthio-substituted 2H-chromene and 1,2-dihydroquinoline systems with high efficiency under mild conditions. Additionally, the(More)
AIM We aimed to assess economic burden of breast cancer (BC) diagnosis and treatment in China through a multicenter cross-sectional study, and to obtain theoretical evidence for policy-making. METHODS This survey was conducted in 37 hospital centers across 13 provinces in China from September 2012 to December 2014. We collected information on the subject(More)
A AgSCF3-mediated radical cascade cyclization/trifluoromethylthiolation of 1,6-enynes triggered by a C-C triple bond is developed. This protocol also provides another opportunity to construct a valuable trifluoromethylthio-substituted polycyclic fluorene system through the formations of one C-SCF3 bond and two C-C bonds in a single step.
An unprecedented Lewis acid catalyzed, high-efficiency synthesis of valuable 2-(quinolin-2-yl)prop-2-en-1-ones via dehydrogenative coupling of propargylic alkynols with quinoline N-oxides is described. This protocol, which tolerates a broad range of functional groups, provides a straightforward pathway to the products 2-(quinolin-2-yl)prop-2-en-1-one(More)
BACKGROUND The increasing prevalence of colorectal cancer (CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment. We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial(More)
