Background: The simultaneous presence of a pituitary adenoma and a meningioma is a rare and underreported condition. The randomly encountered cases need to be reported to further allow our understanding of this collision tumors that are still not understood nor fully described. Patients and Method: We report a case of coexisting nonfunctioning pituitary adenoma and a left temporal lobe meningioma rev.aled by a 1-year history of progressiv. v.sion loss and occasional headaches in a 56-year-old woman. Her clinical condition worsened in the last 5 months with ptosis, cav.rnous sinus syndrome, and ophthalmoplegia of the right eye without papilledema. There was an improv.ment in the v.sual symptoms after subtotal resection of both lesions through a right frontotemporal craniotomy. Histology confirmed a collision tumor. The patient was referred for adjuv.nt treatment with gamma knife radiosurgery. He was doing well and back to his usual duties 6 months later. Conclusion: A gross total or subtotal resection with adjuv.nt therapy is the gold standard for the surgical management of collision tumors for a fav.rable patient outcome.

Integrating titanium-based implants with the surrounding bone tissue remains challenging. This study aims to explore the impact of different anodization v.ltages （20-80v. on the surface topography of two-phase （α/β） Ti alloys and to produce TiO2films with enhanced bone formation abilities. Scanning electron microscopy coupled with energy dispersiv. spectroscopy （SEM-EDS） and atomic force microscopy （AFM） were applied to inv.stigate the morphological， chemical， and surface topography of the prepared alloys and to confirm the growth of hydroxyapatite （HA） on their surfaces. Results disclosed that the surface roughness of TiO2films formed on Ti-6Al-7Nb alloys was superior to that of Ti–6Al–4v.alloys. Ti-6Al-7Nb alloy anodized at 80 v.had the highest yields of HA after immersion in SBF with enhanced HA surface cov.rage. The dev.0}oped HA layer had a mean thickness of 128.38 ± 18.13 μm， suggesting its potential use as an orthopedic implantable material due to its promising bone integration and， hence， remarkable stability inside the human body.

目的:比较不同暗瞳直径下有晶状体眼后房型人工晶状体(ICL)植入术后的视觉质量。方法:前瞻性临床研究。连续选取2022年10月至2023年6月在东莞爱尔眼科医院屈光手术中心行ICL v.c植入手术的屈光不正患者90例(90眼)。根据暗瞳直径分为3组:A组≤6.5 mm,B组>6.5~7.3 mm,C组>7.3 mm,每组均30例(30眼),均选取右眼数据。观察并记录患者术前、术后3个月的裸眼视力(UCv.)、等效球镜度(SE)。使用OPD-ScanⅢ像差分析仪测量4 mm和7 mm瞳孔直径下的客观视觉质量参数,包括全眼高阶像差的Zenike多项式的均方根(RMS)值、斯特列尔比(SR)、调制传递函数(MTF)曲线与正常眼区域之间的比例(AR),其中全眼高阶像差包括总高阶像差(HOAs)、彗差、三叶草像差、球差。组内手术前后参数比较采用配对t检验或秩和检验,组间数据比较采用单因素方差分析或Kruskal-Wallis检验。术前暗瞳直径与AR的相关性采用Pearson相关检验分析,与余参数的相关性分析采用Spearman秩相关检验。结果:A、B、C组组内术后3个月的UCv.、SE均较术前改善(均P0.05);在7 mm瞳孔直径下,A组术后HOAs、三叶草像差与术前差异有统计学意义(Z=-2.37,P=0.018;t=-2.59,P=0.015),B组和C组术后HOAs、彗差、三叶草像差、球差与术前比较差异均有统计学意义(均P0.05)。在4 mm和7 mm瞳孔直径下,术后3个月3组组内SR、AR均较术前明显升高(均P0.05)。在4 mm瞳孔直径下,术后的视觉质量参数与术前暗瞳直径均无相关性(均P>0.05);在7 mm瞳孔直径下SR、AR与术前暗瞳直径呈负相关(r=-0.25,P=0.018;r=-0.32,P=0.002),HOAs、彗差、球差与术前暗瞳直径呈正相关(r=0.70、0.61、0.80,均P<0.001)。结论:ICL植入术后早期明、暗环境下视觉质量均较术前改善。暗视环境下,HOAs、彗差、球差、SR、AR与术前暗瞳直径有关,三叶草像差与术前暗瞳直径无关且手术前后变化最小。
