Objective To introduce the development of dextran-based hydrogel and its drug delivery system in drug sustained and/or controlled release, and to investigate their application in tissue engineering.Methods Related literature was extensively reviewed and comprehensively analyzed. Results In recent years, great progress was made in the studies of dextran-based hydrogels and study on dextran-based intelligent materials became an investigative hotspot especially in tissue engineering. Conclusion Dextran based hydrogel is considered to be a good potential material in field of drug delivery and tissue engineering. Endowed with new characteristics, a series of intelligent biomaterials can be derived from dextran-based hydrogels, which can be widely used in biomedicine. Further study should be done on the industrialization of its interrelated production.
目的:為了探討肝硬化放腹水后應用右旋糖酐40代替人血白蛋白治療頑固性腹水的臨床療效及其經濟性。方法:將216例肝硬化頑固性腹水患者隨機分為A,B,C三組。A組:定期放腹水后應用右旋糖酐40;B組:定期放腹水后應用人血白蛋白或血漿;C組:傳統治療方法,限鈉和不斷增加利尿劑用量。結果:A組分別與B組,C組相比較,其腹水消退時間,ALT復常率,輸血不良反應,住院費用,平均住院日,好轉治愈率,死亡率,以上各項對比均有顯著性差異(Plt;0.05)。血清蛋白量的對比無顯著性差異(Pgt;0.05)。結論:肝硬化放腹水后應用右旋糖酐40治療頑固性腹水,能縮短病程,減少住院日,降低醫療費用,降低死亡率。
