OBJECTIVES To evaluate the clinical characteristics and radiological features of solid pseudopapillary tumor (SPT) and assess surgical therapy strategy. METHODS A retrospective review was performed in 62 patients pathologically confirmed of SPT treated between 2003 and 2014. The clinical features, radiological examinations and surgical strategies were(More)
Given a hierarchical architecture of process control hybrid system, this paper describes a method for constructing a Petri net hybrid controller in its process layer. The process hybrid controller uses PID algorithm for steady state regulation and hybrid switching strategy for large changes. Based on Petri net place invariants the hybrid switching(More)
The production of ROS in mitochondria plays critical role in photodynamic therapy (PDT). The aim of this study was to investigate whether fullerene-based PDT can induce generation of additional endogenous ROS in mitochondria. Chitosan oligosaccharide grafted fullerene conjugate (CS-C60) was synthesized as a model water-soluble fullerene. The relationship(More)
To develop a minipig model of type 2 diabetes that simulates the common manifestations of the metabolic abnormalities and resembles the kidney pathology of type 2 diabetes in the human population, male Chinese Bama minipigs were divided into 2 groups (5 in each) and fed with a control diet (CD) or high-fat/ high-sucrose/ high-cholesterol diet (HFSCD) for 5(More)
microRNA (miRNA) plays critical role in HCC initiation and development, many miRNAs have been reported to regulate HCC progression. In this study, we studied the role of miR-1299 in cell proliferation of HCC. We found miR-1299 was significantly downregulated in HCC cells and tissues. miR-1299 overexpression inhibited cell proliferation and arrested cell(More)
It has been reported that CCAT1 is involved in the development of malignancies including colon cancer and gastric cancer. However, the role of CCAT1 in HCC still remains unknown. Real-time PCR was performed to test the relative expression of CCAT1 in HCC tissues and cell lines. We performed Chi-Square Analysis to study the correlation between clinical(More)
AIMS AND BACKGROUND Hepatocellular carcinoma (HCC) is a dismal malignancy associated with multiple molecular changes. The purpose of this study was to identify the differentially expressed genes and analyze the biological processes related to HCC. METHODS AND STUDY DESIGN Datasets of HCC were obtained from the NCBI Gene Expression Omnibus. Integrated(More)
Scaling the number of cores on processor chips has become the trend for current semiconduction industry (i.e. Intel/AMD many-core CPU, Nvida GPU etc). Current software development should take advantage of those multi-core platforms to achieve high performance. But it is a challenging task to develop parallel software on multiple processor because of the(More)
Digital speckle pattern interferometry (DSPI) fringes contain low spatial information degraded with speckle noise and background intensity. The denoising technique proposed recently based on bi-dimensional empirical mode decomposition (BEMD) could implement noise reduction adaptively. However, the major drawback of BEMD, called mode mixing, has affected its(More)
An improved real-time evolution (RTE) strategy is proposed in an effort to apply RTE more accurately in optimization. The improved RTE tries to consider parameter update and employs a new algorithm as a substitution of the direct search. Algorithm performance comparisons are made among direct search, particle swarm optimization (PSO) and genetic algorithm(More)
