目的观察无缝线小切口白内障囊外摘出联合人工晶状体植入术治疗硬核白内障的疗效。方法观察2组共299例312眼Ⅲ级以上硬核白内障患者,分别应用无缝线小切口白内障囊外摘出联合人工晶状体植入术(小切口组,161眼)和常规超声乳化白内障吸出联合人工晶状体植入术(超乳组,151眼),分别比较手术时间、术后视力、角膜内皮细胞丢失率、术后散光及其他相关并发症发生的差异。结果手术时间:小切口组平均(691±89)s,超乳组平均(663±97)s,2组比较差异无统计学意义(P>0.05)。术后第1天视力≥0.5者小切口组为142眼,超乳组112眼,2组相比差异有统计学意义(P0.05)。角膜内皮细胞丢失率:术后第1天小切口组(10.03±2.87)%,超乳组(18.31±3.34)%;术后1个月小切口组(8.51±2.62)%,超乳组(16.11±3.76)%;2组相比差异均有统计学意义(P1.0DC):小切口组25.47%,超乳组17.22%;角膜水肿:小切口组9.32%,超乳组17.22%,2组比较差异均有统计学意义(P<0.05)。虹膜脱出、后囊膜破裂、切口渗漏等并发症差异无统计学意义。结论对于Ⅲ级以上硬核白内障,无缝线小切口白内障囊外摘出联合人工晶状体植入术是一种较好的治疗选择,值得基层推广。

云计算服务组合是从众多分布在不同云计算平台上的远程服务中选择合适的组件服务来构建可伸缩的松耦合的增值应用.传统的服务组合方法通常将服务选择与服务组合分阶段进行,由于云计算环境的动态性和服务自身演化的随机性,不能保证选择阶段性能最优的服务在组合服务执行阶段依然是最优的.考虑到云计算环境服务组合的动态性和随机性,建立基于部分可观测Markov决策过程(partially observable Markov decision process,POMDP)的服务组合模型SC_POMDP(service composition based on POMDP),并设计用于模型求解的Q学习算法.SC_POMDP模型在组合服务运行中动态地进行服务质量(quality of service,QoS)最优的组件服务选择,且认为组合服务运行的环境状态是不确定的,同时SC_POMDP考虑了组件服务间的兼容性,可保证服务组合对实际情境的适应性.仿真实验表明,所提出的方法能成功地解决不同规模的服务组合问题,在出现不同比率的服务失效时,SC_POMDP仍然能动态地选择可用的最优组件服务,保证服务组合能成功地执行.与已有方法相比,SC_POMDP方法所选的服务有更优的响应时间和吞吐量,表明SC_POMDP可有效地提高服务组合的自适应性.

YBa2Cu3-xVxO7-y(x=0, 0.1, 0.2, 0.3, 0.4, 0.5 and 0.6) superconductors have been prepared. X-ray diffraction shows that the system remains orthorhombic for all compositions studied, but for x > 0.4 V2O5 was detected as an impurity phase. Substitution of V5+ for Cu2+ occurs in the Cu(2) sites on the Cu(2)-O planes. The introduction of the high valence element, vanadium, produces the extra free-electrons. These electrons recombine with the positive carrier of the system. It makes depression of the mobility and the Hall number of YBa2Cu3-xVxO7-v and also results in a depression of TC.

The pathophysiology of ischemic stroke is complex and multifactorial,involving various forms of cell death such as apoptosis,autophagy,and necrosis.A recent study suggests that oxidative and inflammatory stress can induce ferroptosis,a specialized form of cell death characterized by the accumulation of lipid peroxides dependent on intracellular iron overload(li and Jia,2023).
