血卟啉衍生物激光3号时间分辨荧光光谱学

科学通报 1989年第9期34卷 700-703页

作者：刘文清 r.ramponi r.Cubeddu 刘颂豪中国科学院安徽光学精密机械研究所意大利米兰工业大学物理研究所

用血卟啉衍生物(HpD)作为光敏药物的光动力学疗法(PDT)已愈来愈多地用于恶性肿瘤的局部治疗中。这种技术的成功是由于HpD在肿瘤细胞中的积聚程度大于正常细胞,当肿瘤细胞中的HpD用红光敏化时,吸收足够的能量引起肿瘤细胞被杀死的结果。

采用改进后的时间相关单光子计数系统研究了血卟啉衍生物HpD激光3号在磷酸盐缓冲液中浓度0.625μg/ml至10μg/ml的时间窗荧光谱,这是在不同延迟时间测量的一种光谱。根据测量的光谱积分荧光寿命分别为2ns和15ns,选择两个不同宽度的时间窗,分别延迟0和18ns,来分析样品中各个荧光组份对整个光谱的贡献。峰值波长615am的荧光主要是HpD中单体的贡献,具有较长的荧光寿命(～15ns),而波长630～660nm区的荧光则是荧光寿命约0.7ns的聚合物和荧光寿命约2.3ns的多聚物剩余部份与“自由生色团”相互作用的结果。所得结果还与国外类似样品DHE作了比较。

AIM To clarify the quality of the studies indicating lesion size and/or containment as prognostic indicators of bone marrow stimulation(BMS) for osteochondral lesions of the talus(OLT). METHODS Two reviewers searched the Pub Med/MEDLINE and EMBASE databases using specific terms on March 2015 in accordance with the Preferred reporting Items for Systemic reviews and Meta-Analyses guidelines. Predetermined variables were extracted for all the included studies. Level of evidence(LOE) was determined using previously published criteria by the Journal of Bone and Joint Surgery and methodological quality of evidence (MQOE) was evaluated using the Modified Coleman Methodology Score. rESULTS This review included 22 studies. Overall, 21 of the 22(95.5%) included studies were level Ⅳ or level Ⅲ evidences. The remaining study was a level Ⅱ evidence. MQOE analysis revealed 14 of the 22(63.6%) included studies having fair quality, 7(31.8%) studies having poor quality and only 1 study having excellent quality. CONCLUSION The evidence supporting the use of lesion size and containment as prognostic indicators of BMS for OLTs has been shown to be of low quality.
