1High-performance hot-warm rolled Zn-0.8Li alloy with nano-sized metastable precipitates and sub-micron grains for biodegradable stents显示文摘Fabricated through a newly developed hot-warm rolling process,Zn-0.8 Li(wt%)alloy has ideal strength and ductility far beyond the mechanical benchmark of materials for biodegradable stents.Precipitation of needle-like Zn in primary p-LiZn4 phase is observed in Zn-Li alloy for the first time.Orientation relationship between them can be described as[1-213]β//[2-1-10](Zn),(10-10)βabout 4.5°from(0002)(Zn).Zn grains with an average size of 640 nm exhibit strong basal texture,detected by transmission electron back-scatter diffraction.Li distribution is determined by three-dimensional atom probe,which reveals the formation of nano-sized metastableα-Li2Zn3 precipitates with a number density of 7.16×10^22 m^-3.The fine lamellar Zn+β-LiZn4 structure,sub-micron grains and the nano-sized precipitates contribute to the superior mechanical properties.Zhen Li Zhang-Zhi Shi Yuan Hao Hua-Fang Li Xue-Feng Liu Alex AVolinsky Hai-Jun Zhang Lu-Ning Wang 2019Journal of Materials Science & Technology2019,35,11:6
2Comparison of intravitreal ranibizumab and bevacizumab for the treatment of macular edema secondary to retinal vein occlusion显示文摘AIM: To compare the efficacy of ranibizumab and bevacizumab for macular edema due to retinal vein occlusion(RVO). ·METHODS: A retrospective study was conducted at a single academic institution. Eighty-one patients na觙ve to anti-VEGF therapy with RVO and macular edema were identified. Twenty-six eyes were treated with ranibizumab,33 eyes with bevacizumab,and 22 eyes with bevacizumab then switched to ranibizumab(crossover). The main outcome was change in visual acuity at 3 months,6 months,and final visit. ·RESULTS: The mean visual acuity improved from 20/80 to 20/40 in the ranibizumab(R) group and from 20/125 to 20/60 in the bevacizumab(B) group(P =0.66). The mean change in central subfield thickness(CST) was-186 and 212μm,respectively(P =0.69). Mean time between injections was 94±21.1d in the R group and 103.8 ±10.5d in the B group(P =0.78). In the crossover group,mean initial visual acuity was 20/125,reached 20/60 at crossover,and remained 20/60 at conclusion(P =0.91). ·CONCLUSION: Both ranibizumab and bevacizumab are effective for the treatment of RVO and appear to have similar visual and anatomic outcomes. Changing treatments from bevacizumab to ranibizumab did not result in further gains in visual acuity.Alex Yuan Baseer U.Ahmad David Xu Rishi P.Singh Peter K.Kaiser Daniel F.Martin Jonathan E.Sears Andrew P.Schachat Justis P.Ehlers 2014International Journal of Ophthalmology(English edition)2014,7,1:4
3Penile prosthesis implantation in Chinese patients wit severe erectile dysfunction: 10-year experience显示文摘我们回顾地与严重可勃起的机能障碍(SED ) 在中国病人评估了阴茎修复术培植(PPI ) 的临床的结果。从 2000 年 7 月到 2011 年 12 月, 224 个病人(吝啬的年龄:35.9 ± 11.8 年,变化:20-75 年) 在我们的中心根据标准 PPI 过程由富有经验的外科医生与 SED 经历了 PPI。韧性的修复术(AMS 650 ) 在 45 种情况中被植入(20.1 %) ,并且三片的可膨胀的修复术(AMS 700 CXM 或 AMS 700 CXR ) 在 179 种情况中被植入(79.9 %) 。包括手术后的复杂并发症,临床的功效和夫妇满足,外科的结果被评估在上比手术后地使用医药记录抽象的 6 个月, IIEF-5,生活(QoL ) 的质量分数,和病人 / 搭挡的性满足分数由 Bhojwani 等求婚了。为学习合格的 224 个病人, 201 使遭到(89.7 %) 完成的后续。所有能与吝啬的手术后的 IIEF-5 病人执行性交柱子 PPI, QoL 分数是 20.02 ± 2.32 和 5.28 ± 0.76,分别地它显著地与外科手术前的分数相比被改进(6.29 ± 1.5 和 2.13 ± 0.84, P< 0.01 ) 。201 个人,机械失灵发生在四种情况中(2.0 %) 并且三个盒子被重新植入新设备,和二个盒子(1.0 %) 开发了阴茎的温和弯曲。有感染的阴囊的侵蚀与糖尿病 mellitus 发生在一种情况中(0.5 %) 并且植入的 AMS 的要求的完全的移动 700 CXM。令人满意的性交被 178 个人两次至少每月报导(88.6 %) ,并且对 PPI 外科的全面满足被 89.0 % 报导;人和 82.5 %搭挡。在三片的可膨胀的修复术组的耐心的满足比在韧性的修复术组高(P< 0.05 ) 。然而,在 prostheses 的类型之间,满足没在搭挡调查不同。PPI 是一种安全、有效的治疗选择因为有 SED 和富有经验的外科医生的中国病人根据标准 PPI 执行 PPI 过程能减少 PPI 的手术后的复杂并发症并且能改进耐心的满足比率和 QoL。Wei-Dong Song Yi-Ming Yuan Wan-Shou Cui Alex K Wu Yi-Chen Zhu Jing Liu Lin Wang Guang-Yi Ba Jing Peng Zhi-Chao Zhang Bing Gao Ying-Lu Guo Tom F Lue Zhong-Cheng Xin 2013Asian Journal of Andrology2013,15,5:3

6Corneal epithelial defects following vitreoretinal surgery:incidence and outcomes from the DISCOVER study显示文摘AIM:To investigate the incidence,risk factors,clinical course,and outcomes of corneal epithelial defects(CED)following vitreoretinal surgery in a prospective study setting.METHODS:This was a post-hoc analysis of all participants in DISCOVER intraoperative optical coherence tomography study.Subjects with CED 1 d after surgery without intraoperative corneal debridement was defined as the postoperative CED group.Subjects who underwent intraoperative debridement were defined as intraoperative debridement group.Eyes were matched 2:1 with controls(eyes without postoperative CED)for comparative assessment.The primary outcomes were the incidence of CED on postoperative day one and the incidence of required intraoperative debridement.Secondary outcomes included time to defect closure,delayed healing(>2 wk),visual acuity(VA)and presence of scarring at one year and cornea consult.RESULTS:This study included 856 eyes that underwent vitreoretinal surgery.Intraoperative corneal debridement was performed to 61(7.1%)subjects and postoperative CED developed spontaneously in 94(11.0%)subjects.Significant factors associated with postoperative CED included prolonged surgical duration(P=0.003),diabetes mellitus(P=0.04),postoperative ocular hypotension(P<0.001).Prolonged surgical duration was associated with intraoperative debridement.Delayed defect closure time(>2 wk)was associated with corneal scar formation at the end of the 1 y in all epithelial defect subjects(P<0.001).The overall rate of corneal scarring for all eyes undergoing vitrectomy was 1.8%.CONCLUSION:Prolonged duration of surgery is the strongest factor associated with both intraoperative debridement and spontaneous postoperative CED.Delayed defect closure is associated with a greater risk of corneal scarring at one year.The overall rate of corneal scarring following vitrectomy is low at<2%.Kubra Sarici Daniel Petkovsek Alison Martin Alex Yuan Jeffrey M.Goshe Sunil K.Srivastava Jamie L.Reese Justis P.Ehlers 2022International Journal of Ophthalmology(English edition)2022,15,1:1
