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 new drug delivery system (DDS), ciprofloxacine/tricalcium phosphate delivery capsule (CTDC) was developed by loading a broad-spectrum antibiotic ciprofloxacine into the central cylindrical cavity of tricalcium phosphate capsule. The new system showed good biocompatibility and could degrade gradually in our preliminary studies.In vitro study showed that(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)
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 in clinical(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)
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)
With the development of Automatic Identification System (AIS), more and more vessels are equipped with AIS device, which is a new tool for vessel monitoring and marine safety. In this paper, we compared the function of AIS and radar, the traditional tool for Vessel Traffic Service (VTS). And then we discussed the necessity of data fusion of the same target(More)
With the aim to fit the sin wave curve of a multi-position strap-down north seeking system and to calculate the real north angle accurately, the principles of the system and the algorithm of singular value decomposition(SVD) are introduced. The factors influencing the measuring precision are also analyzed. Then, the algorithm is adopted to fit curves.(More)
Due to its radial velocity, the range walk (linear term of range migration) of a moving target in synthetic aperture radar (SAR) image is usually bigger than that of the stationary target. Hence in the time domain after range cell migration correction, the trajectory of most moving target is usually characterized by an approximate sloping line, while the(More)
