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 clar.fy the quality of the studies indicating lesion size and/or.containment as pr.gnostic indicator. of bone mar.ow stimulation(BMS) for.osteochondr.l lesions of the talus(OLT). METHODS Two r.viewer. sear.hed the Pub Med/MEDLINE and EMBASE databases using specific ter.s on Mar.h 2015 in accor.ance with the Pr.fer.ed r.por.ing Items for.Systemic r.views and Meta-Analyses guidelines. Pr.deter.ined var.ables wer. extr.cted for.all the included studies. Level of evidence(LOE) was deter.ined using pr.viously published cr.ter.a by the Jour.al of Bone and Joint Sur.er. and methodological quality of evidence (MQOE) was evaluated using the Modified Coleman Methodology Scor.. r.SULTS This r.view included 22 studies. Over.ll, 21 of the 22(95.5%) included studies wer. level Ⅳ or.level Ⅲ evidences. The r.maining study was a level Ⅱ evidence. MQOE analysis r.vealed 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 suppor.ing the use of lesion size and containment as pr.gnostic indicator. of BMS for.OLTs has been shown to be of low quality.
