Influence of Orbital Implant Length and Diameter on Stress Distribution: A Finite Element Analysis.

Purpose: A mathematical simulation of stress distribution around orbital implants was used to determine which length and diameter of implants would be best to dissipate stress.

Methods: An integrated system for computed tomography data was utilized to create a 3-dimensional model of craniofacial structures. The model simulated implants placed in the 7, 11, and 12 o'clock positions of the orbital rim.

[Research progress in heterogeneity of human CD4(+)FOXP3(+)T cells].

It is now established that CD4(+)CD25(+)regulatory T (Treg) cells expressing transcription factor FOXP3, a regulatory subpopulation of T cells, is indispensable for the maintenance of immunological self-tolerance and immune homeostasis. FOXP3 expression in Treg cells is specific and it is the key control factor for the development, activation and function of Treg cells. At present, CD4(+)FOXP3(+)T lymphocytes are often used to define Treg cells for scientific research.

[Curative effect of interleukin 11 on chronic idiopathic thrombocytopenic purpura].

The aim of this study was to investigate the circulating levels of IL-11 in the patients with chronic idiopathic thrombocytopenic purpura (CITP), and its significance, and to evaluate the curative effect of rhIL-11 on CITP. The level of IL-11 in patients with CITP was determined by ELISA before and after treatment, respectively. 1.
