INTRODUCTION Laparoscopic procedures for pancreatic surgery have been significantly improved recently; however, only a limited number of successful laparoscopic or laparoscopy-assisted pancreaticoduodenectomy (PD) have been reported. The limitations could be attributed to the complexity of the reconstruction procedures under laparoscopic observation and the(More)
BACKGROUND/AIMS To evaluate the prognostic value of surgical operation-related factors in patients with primary liver cancer (PLC). METHODOLOGY A retrospective study was carried out analyzing the data of 114 patients with PLC undergoing hepatic resection from January 2002 to December 2009. Survival rates were analyzed using Kaplan-Meier curve and log-rank(More)
OBJECTIVE To analyze transforming growth factor beta-induced (TGFBI) gene mutations in 2 Chinese families with Thiel-Behnke corneal dystrophy (TBCD). METHODS Forty-five individuals in 2 Chinese families with TBCD were examined using slitlamp biomicroscopy. Genomic DNA was extracted from peripheral leukocytes of affected and unaffected family members.(More)
In this paper, DE algorithm is presented to solve the earliness tardiness (E/T) hybrid flow-shop scheduling problem (HFSP). The mathematical model of E/T based on DE is constructed and the key application steps in DE are also discussed in detail. In the implement process of the method, DE is used to take global optimization and find which machine the jobs(More)
BACKGROUND The WHO's three-step guideline for cancer pain management has been introduced in China; however, there remain large differences in the standards of cancer pain management between China and other developed countries. This survey was carried out to determine the degree of physician knowledge on morphine use and the factors that impede morphine use(More)
Using speech signal processing technology to detect depression arouses more and more interest recently. But even so, the source of feature extraction is only restricted in the amplitude representation and the important role of the phase, the other half part of signal information, has been ignored. It is the first time that this paper pays attention to the(More)
To gain transplantation tolerance between donor organs and hosts is the ultimate goal of all sorts of organ transplantations. Induction of regulatory T cells has been demonstrated to lead to transplantation tolerance. This paper will review subsets of regulatory T cells, the role and mechanisms of CD4(+)CD25(+) regulatory T cells (Tregs) in graft rejection(More)
A blind robust digital image watermarking scheme using chaotic encryption and HVS in DWT domain is presented. Firstly, the original image is transformed into some sub-band coefficients using discrete wavelet transformation (DWT), and then the binary image watermark signal is encrypted using logistic chaos map before it is embedded. Taking into account the(More)
Cognitive tunneling, the inefficient joint processing of superimposed head-up display (HUD) symbology and the out-the-window scene, was found in an earlier study to occur as a result of locating the HUD symbology near (in visual angle) the outside scene information (Foyle, McCann, Sanford & Schwirzke, 1993). They concluded that cognitive tunneling could be(More)
In order to fit the sin wave curve of a multiposition strap-down north seeking system and to calculate the real north angle accurately, the data collected from the Dynamically tuned gyro(DTG) must be filtered firstly to reduce the noise jamming. The principles of the system are introduced. The factors influencing the measuring precision are also analyzed.(More)
