Objective: To explore the mechanisms resulting in the recurrence of urethral scar which make urethral strictures difficult to be cured, a series experiments were conducted to find potential effective factors involved in urethral scar formation and degradation, including the studies of extracellular matrix component of urethral stricture scar, the characteristics of urethral scar fibroblast, and the effects of urine on urethral fibroblast in vitro, as well as the studies to compare the difference of collagenase activity, type Ⅰ collagen and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the tissues and cultured fibroblasts from normal urethra and strictured urethra respectively, and the studies to investigate the effect of antisense TIMP-1 oligodeoxyonucleotide on cell proliferation and collagenase activity of urethral scar fibroblast.

Methods The design of burn scar flaps in tendo calcaneus was improved. In virtue of accessary transverse incision, ankle joints were reposited, without incision or free liberation of the internal side's scar flap.Results Improved scar flaps in tendo calcaneus met the need of ankle joints' functional reposition with an additional benefit that internal scar flaps were not prone to necrosis.

Results:The positive rates of TSP- 1 mRNA in hypertrophic scars and keloid were lower than those in normal skin and surgical scar. MVC was higher in the cases with negative expression of TSP - 1 mRNA than the ones with positive expression of TSP - 1 mRNA. MVC was higher in the hyperstrophic scar and keloid than in normal skin and surgical scar.

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
