In current study, we developed a highly sensitive method for the quantitative profiling of acidic phytohormones. Tandem solid-phase extraction (SPE) and liquid-liquid extraction (LLE) was employed to efficiently purify acidic phytohormones, which were further derived by 3-bromoactonyltrimethylammonium bromide (BTA) to increase the ionization efficiency in(More)
OBJECTIVE To investigate the clinical epidemiology of intrahepatic cholelithiasis in Guangxi area, China. METHODS 8585 cases of cholelithiasis proved by surgery in a period of 19 years were analyzed retrospectively. Data were collected and analyzed by computer software package PEMS. RESULTS Cases of intrahepatic cholelithiasis accounted for more than(More)
Plant hormones play crucial roles in plant growth and development. However, up to date, identification and quantification of acidic plant hormones with trace amount in complicated plant matrix is still a challenge. In current study, we developed a high sensitive assay for the determination of acidic plant hormones in rice by combining capillary(More)
Skimmed milk spiked with five organophosphorus pesticides (OPPs), chlorpyrifos, diazinon, fenitrothion, malathion and methyl parathion, was fermented by ten lactic acid bacteria (LAB) and four strain combinations at 42°C for 24h. OPPs left in the samples at different times were extracted, purified, detected by gas chromatography and calculated for(More)
Although plasma membrane (PM) cholesterol-rich and -poor domains have been isolated by subcellular fractionation, the real-time arrangement of cholesterol in such domains in living cells is still unclear. Therefore, dehydroergosterol (DHE), a naturally occurring fluorescent sterol, was incorporated into cultured L-cell fibroblasts. Two PM markers, the(More)
It was previously reported that excessive arsenic trioxide would produce cardiovascular toxicity. Bone marrow mesenchymal stem cells (BMSCs) have been shown to play a supporting role in cardiovascular functions. The increasing apoptosis of BMSCs commonly would promote the development of cardiovascular diseases. Thus we hypothesize that arsenic trioxide(More)
Keloids and hypertrophic scars are significant symptomatic clinical problems characterized by the excessive and abnormal deposition of collagen-based extracellular matrix (ECM) components. However, the molecular basis of keloid and hypertrophic scar formation has not been fully elucidated. Here, we demonstrated that down-regulation of the transcription(More)
Urokinase type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) have been proposed to play key roles in extracellular matrix (ECM) deposition in hypertrophic scars (HS). Here, we found that in HS fibroblasts (HFs) miR-181c and miR-10a were differentially-expressed and targeted uPA and PAI-1, respectively. The production of Type 1(More)
Fibrosis, tightly associated with wound healing, is a significant symptomatic clinical problem. Inflammatory response was reported to be one of the reasons. MiR-155 is relatively related with the development and requirement of inflammatory cells, so we thought reduce the expression of miR-155 in wound sites could improve the quality of healing through(More)
BACKGROUND The majority of patients with hepatocellular carcinoma (HCC) have coexisting cirrhosis or chronic hepatitis, often complicated by diabetes mellitus. In the current study, the authors evaluated the impact of diabetes mellitus on the prognosis of patients with HCC. METHODS Among 581 patients with HCC who had been diagnosed and treated between(More)
