Functional engineering of musculoskeletal tissues generally involves rapid expansion of progenitor cells in vitro while retaining their potential for further differentiation and then induction in specific culture conditions. The autologous adipose-derived stromal cells (ASCs) are considered to contain pluripotent mesenchymal stem cells. Imaging with(More)
OBJECTIVE The purpose of the study was to explore the anti-tumor effect of ultrasound -targeted microbubble destruction mediated herpes simplex virus thymidine kinase (HSV-TK) suicide gene system on mice hepatoma. METHODS Forty mice were randomly divided into four groups after the models of subcutaneous transplantation tumors were established: (1) PBS;(More)
OBJECTIVES To observe the synthesis of Toll-like receptor (TLR) 4 protein and its mRNA expression in Kupffer cells (KCs) and evaluate the role of TLR 4 in liver injury to rats through alcohol-induced liver disease. METHODS Twenty-eight Wistar rats were divided into two groups: ethanol-fed (group E) and control (group C). Group E rats were given ethanol at(More)
BACKGROUND High-intensity focused ultrasound (HIFU) is a widely applied to treatment for unresectable hepatocellular carcinoma. However, insufficient HIFU can result in rapid progression of the residual tumor. The mechanism of such rapid growth of the residual tumor after HIFU ablation is poorly understood. OBJECTIVE The aim of this study was to(More)
To identify genes involved in pigment gland morphogenesis in cotton, gene expression was profiled using genechip (Affymetrix) during pigment gland morphogenesis in cotton variety Xiangmian-18, which has glandless seeds but glanded plants, and a glandless line, N5. The results showed that 303 genes were differentially expressed by a factor greater than two(More)
Systemic inflammation affects hemostasis during severe acute pancreatitis (SAP). A hypercoagulable state occurs more frequently in SAP, which is not fully detected by traditional coagulation testing. The aim of this study was to evaluate the contribution of clot formation and lysis (CloFAL) assay to improve monitoring of global coagulation in patients with(More)
The aim of this study was to develop a bioactive membrane for inducing bone regeneration. The membrane was composed of polylactic acid, collagen, recombinant human bone morphogenetic protein-2 (rhBMP-2). The PLA + collagen + rhBMP-2 membrane was fabricated by solvent-casting and cool-drying. The mechanic properties of this compound membrane were tested. The(More)
OBJECTIVE To investigate the dynamic features of angiogenesis in residual tumors after high intensity focused ultrasound (HIFU),and to determine the temporal effect and mechanism of hypoxia inducible factor-2 alpha (HIF-2a) in the angiogenic process of residual tumors. METHODS Xenograft tumors of HepG2 cells were generated by subcutaneously inoculating(More)
Exome and whole-genome sequencing studies have drawn attention to the role of somatic mutations in SWI/SNF chromatin remodeling complexes in the carcinogenesis of hepatocellular carcinoma (HCC). Here, we explored the molecular mechanisms underlying the biological roles of AT-rich interactive domain 2 (ARID2) in the pathogenesis of HCC. We found that ARID2(More)
OBJECTIVE To summarize the diagnosis and treatment of juxta-ampullary duodenal diverticulum (JAD) in our hospital. METHODS Of 5000 consecutive endoscopic retrograde cholangiopancreatography (ERCP) performed in our department, 225 patients were diagnosed with JAD and treated. All patients were classified based on the location of Ampullae of Vater in(More)
