Anatomy of the carpal vascular network and its clinical correlation to the distal forearm flap;

Anatomic observation of the ankle vascular network and its clinical correlation to the blood supply distally based flaps of the lower leg;

Research on retinal vessels detection method based on the model of the retina vascular network;

Retinal blood vessel is used as a human biologic characteristics for personal verification in this paper.

A correlative node method for the application of high level secret and security is proposed, including the ideal of the method, the extraction of nodes as feature in the image of retinal blood vessels, the alignment in horizontal with the centroid and the furthest node, the matching criterion of nodes between images.

Objective:To study the effects of superficial venous trunk (SVT) and its norishing vessels on revascularization in reverse-flow random flaps, to make clear picture of the problem whether the existence of SVT and its norishing vessels can improve the revascularization of reverse-flow flaps early in the transplantation so as to supply the theoretical evidences to the clinical applications.

In order to find the answers to these questions,based on the model of endothelial cell factor diffusion to surrounding tissue, we attempt to introduce a series of assumptions about capillary network construction.
