Experimental Study on Effects of Adipose-Derived Stem Cell-Seeded Silk Fibroin Chitosan Film on Wound Healing of a Diabetic Rat Model.

Background: Wound healing is a complex process that relies on growth factors and stimulation of angiogenesis. Tissue engineering materials composed of adipose-derived stem cells (ADSCs) and silk fibroin (SF)/chitosan (CS) may be able to solve this problem. The aim of this study was to investigate the wound-healing potential of ADSC-seeded SF/CS in streptozotocin-induced diabetic rats.

[Diagnosis and treatment of pediatric anismus].

Objective: To explore the diagnosis and treatment methods of pediatric anismus.

Methods: Twenty-nine patients with idiopathic chronic constipation, diagnosed with anismus by colon barium contrast and anorectal manometry from Nov. 2001 to Nov.

[Diagnosis and surgical management of adult Hirschsprung disease].

Objective: To investigate the diagnosis and surgical treatment of adult Hirschsprung disease (AHD).

Methods: Clinical data of 10 patients with AHD undergoing operation from May 1985 to May 2005 were analyzed retrospectively.

Results: There were 7 males and 3 females with an age ranged from 14 to 40 years.
