AIM A study was performed to investigate the impact of comorbid anxiety and depression (CAD) on quality of life (QOL) and cellular immunity changes in patients with digestive tract cancers. METHODS One hundred and fifty-six cases of both sexes with cancers of the digestive tract admitted between March 2001 and February 2004 in the Department of Medical(More)
We reported previously that regenerated Antheraea pernyi silk fibroin (A. pernyi SF) could support the attachment and growth of human bone marrow mesenchymal stem cells (hBMSCs). In this work, the immunosupressive effects of hBMSCs cultured on the A. pernyi SF films on T-cells were investigated in vitro. The production of IL-6, CD80, CD86 and HLA-DR by the(More)
Silk fibroin of the silkworm Bombyx mori has been studied extensively, while the research on Antheraea pernyi silk fibroin (A. pernyi SF) in biomaterials is only at an early stage. In this study, the attachment, morphology, growth and phenotype of human bone marrow derived mesenchymal stem cells (hBMSCs) cultured on the regenerated A. pernyi SF films were(More)
A DSP-based design method of finger vein recognition was proposed, and a finger vein authentication system FV-1 was developed. In this system, finger vein images were captured with infrared, and normalized through rotation correction, then they were segmented and thinned to wipe off useless segments. Finally, features on vein points were obtained and two(More)
The high repetition rate 10 J/10 ns Yb:YAG laser system and its key techniques are reported. The amplifiers in this system have a multi-pass V-shape structure and the heat in the amplifiers is removed by means of laminar water flow. In the main amplifier, the laser is four-pass, and an approximately 8.5 J/1 Hz/10 ns output is achieved in the primary test.(More)
Thermal stress can induce birefringence in a laser medium, which can cause depolarization of the laser. The depolarization effect will be very severe in a high-average-power laser. Because the depolarization will make the frequency doubling efficiency decline, it should be compensated. In this paper, the thermal characteristics of two kinds of materials are(More)
OBJECTIVE To investigate the efficacy, safety and the life quality improvement of uroacitides injection in the treatment for patients with advanced malignant tumors. METHODS A total of 160 patients with advanced stage cancers were enrolled into this multicenter, open and non-randomized phase II clinical trial, including cancers of the lung (33 cases),(More)
