2Efficacy of selective laser trabeculoplasty following incisional glaucoma surgery显示文摘AIM: To evaluate the efficacy of selective laser trabeculoplasty(SLT) in glaucomatous eyes with previous incisional glaucoma surgery. METHODS: A retrospective cohort of eyes that underwent SLT at a single institution from 2013-2015 were followed for 1 y. Reduction in intraocular pressure(IOP) following SLT was evaluated in eyes with prior trabeculectomy with Ex Press mini shunt(Alcon, Ft Worth, TX, USA), Ahmed valve(New World Medical, Cucamonga, CA, USA), or combined phacoemulsification-trabeculectomy. A control group was included with eyes without prior surgery that underwent SLT. Success was defined as >20% drop in IOP from pre-SLT baseline. RESULTS: One-hundred and six eyes were included with 53 in both the prior glaucoma surgery(PGS) and no prior glaucoma surgery(NPGS) groups. Mean pre-SLT IOP was 19.2±4.3 and 20.6±6.0 mm Hg for PGS and NPGS groups, respectively(P=0.17). Both groups produced statistically significant IOP reductions at 1 and 6 mo(P<0.04). At 6 mo, mean IOP reduction reached 7.3% and 10.8% for the PGS and NPGS groups, respectively(P=0.42). Overall, 27.9% and 31.7% of eyes in PGS and NPGS groups met success criteria at 1 y(P=0.70). In the PGS group, eyes with baseline IOP ≥21 mm Hg had IOP reductions of 18.1%(P<0.001), 16.7%(P<0.01), and 8.4%(P=0.31) compared to eyes with baseline IOP <21 mm Hg who had IOP reductions of 2.3%(P=0.39), 3.4%(P=0.19), and 1.1%(P=0.72) at 1, 6 mo, and 1 y, respectively. CONCLUSION: SLT is efficacious in eyes with prior incisional glaucoma surgery and results in similar IOP reductions compared to eyes without PGS. A larger IOP reduction is observed following SLT in eyes with higher pre-SLT IOP.Robert Allan Sharpe Leah L Kammerdiener David B.Williams Sudeep K.Das Matthew J.Nutaitis 2018International Journal of Ophthalmology(English edition)2018,11,1:3

5紫硫镍矿交代镍黄铁矿的水热反应机理及动力学显示文摘本工作首次在实验室条件下对浅生区紫硫镍矿(Ni,Fe)3S4交代镍黄铁矿(Ni,Fe)9S8水热反应的机理及动力学进行了研究。起始反应矿物采用高纯自然镍黄铁矿,合成纯镍黄铁矿或合成镍黄铁矿-磁黄铁矿集合体。反应pH值采用0.2M醋酸-醋酸纳缓冲溶液控制在3~5的范围内。反应进程由X-射线衍射物相定量分析及扫描电镜观察进行跟踪。结果表明,当反应温度恒定在80℃时,交代20(4)%的镍黄铁矿需792h。相同条件下加入少量H2S可将反应速率提高一倍。当反应在125℃饱和蒸汽压水热环境下进行时,完全交代纯镍黄铁矿需约168h。此过程由于磁黄铁矿的存在而被催化,交代集合体中的镍黄铁矿仅需68h,进一步反应磁黄铁矿被交代成白铁矿。磁黄铁矿的催化作用可能源于溶解产生的微裂纹加速了流体的传质过程。当反应温度升高至145℃时,速率反而下降,不遵循Arrhenius经验规律。动力学分析得80℃速率常数介于5.8×10-8~3.0×10-7/s之间,125℃及145℃速率常数分别介于2.8×10-6~2.08×10-5/s及1×10-6~5.1×10-6/s之间,远高于同温度下固相扩散反应的速率常数,表明该反应在地质时标上为一快速反应。此外,用背散射电子显微技术对矿物表面形貌进行了分析,发现交代产物紫硫镍矿具有颗粒细小及存在微裂纹等特征,与自然界浅生矿床中的紫硫镍矿非常相似;电镜实验还表明该交代作用是一个典型的耦合溶解-再沉淀反应。其耦合机制的驱动力可能与反应界面处微空隙对流体饱和度的控制有关。夏方 陈国荣 Allan PRING Joёl BRUGGER Yung NGOTHAI Brain O'NEILL Chris COLBY Christophe TENAILLEAU 王海鹏 杨云霞 2007地质学报2007,81,10:2
