To investigate the fluorescence dynamic change of protoporphyrin IX in bladder carcinoma cell induced by 5-ALA and the influence of 5-ALA concentration and pH on fluorescence of PpIX. 2. To discuss the biodistribution and express of PpIX in bladder wall of different lesions by method of instilling of 5-ALA into bladder cavity. 3. To discuss the clinical value of the fluorescence diagnosis in early detection of bladder cancer and the radicality of bladder tumor resection under fluorescence cystoscopy.

本研究目的：1了解5-ALA诱导膀胱癌细胞内生原卟啉IX荧光随时间的动力学变化及5-ALA的浓度、pH值对产生PpIX荧光的影响。2通过膀胱灌注5-ALA探讨其所诱导内生PpIX荧光在膀胱上皮中分布及不同病变表达上的差异。3探讨5-ALA诱导荧光膀胱镜检对发现早期膀胱癌的临床应用价值及在荧光膀胱镜下膀胱肿瘤电切治疗的彻底性。

Some innate digital palmar branches could be seen at the pedicle of flyback finger flaps in which veins can be stained to black soon after infusion.It indicated that the blood circulation of arteries to capillaries to veins have completed.The radiogram of flaps showed that the overall transmittancy has been decreased and some blood vessels were visible radiologically.

指背逆行皮瓣的蒂部可见有指掌侧固有动脉的分支，灌注后可见皮瓣内静脉即刻充盈黑染，说明实验皮瓣已完成"血液"从动脉-毛细血管-静脉的循环过程，皮瓣X线造像显示整体透光度减低，皮瓣内有血管显影。
