[Iterated Tikhonov Regularization for Spectral Recovery from Tristimulus].

Reflective spectra in a multispectral image can objectively and originally represent color information due to their high dimensionality, illuminant independent and device independent. Aiming to the problem of loss of spectral information when the spectral data reconstructed from three-dimensional colorimetric data in the trichromatic camera-based spectral image acquisition system and its subsequent problem of loss of color information, this work proposes an iterated Tikhonov regularization to reconstruct the reflectance spectra. First of all, according to relationship between the colorimetric value and the reflective spectra in the colorimetric theory, this work constructs a spectral reconstruction equation which can reconstruct high dimensional spectral data from three dimensional colorimetric data acquired by the trichromatic camera.

[Research on Developping the Colorimetric Correction Method Based on Wide Gamut Spectral Color Dataset].

In cross-media digital color imaging workflow, the colorimetric information transform among various digital medias always suffers from large transform errors, due to the difference among the lighting illuminants and the digital devices. Colorimetric correction aims at avoiding the colorimetric transform mismatch and thus improving the color transform accuracy comprehensively. Till now, two kinds of colorimetric transform methods have been proposed, which are the chromatic adaptation transform and the regression-based transform.

Sirolimus as primary immunosuppressant for calcineurin inhibitor-related renal insufficiency after liver transplantation.

Background: Calcineurin inhibitor-related renal toxicity affects patient and graft survival in transplant recipients. This study aimed to determine whether sirolimus is effective and safe in treating renal insufficiency related to tacrolimus after liver transplantation.

Methods: Tacrolimus for primary immunosuppression was used in 16 patients after liver transplantation.

[Laparoscopy assisted total mesorectal excision for rectal cancer].

Objective: To evaluate the feasibility of laparoscopy assisted total mesorectal excision (TME) for rectal cancer.

Method: From March 2000 to November 2003,67 patients with rectal cancer received laparoscopy assisted TME,in whom 45 cases received anterior resection (AR),and 22 cases received abdominal perineal resection (APR).

Results: The operation was performed according to the rules of TME.
