优化ICL V4c植入术的临床研究进展

随着有晶状体眼后房型人工晶状体植入术的发展及可植入式接触镜(ICL)的不断改进,ICL V4c植入术目前已经成为矫正中高度近视的主流术式之一。术后拱高是评价手术安全性的重要指标,在常规ICL V4c植入手术的基础上,如何优化手术以获得更理想的拱高是近年来学者们研究的热点。本文以术前检查、术中手术设计以及术后随访为中心,总结分析优化ICL V4c植入手术的方案,为提高手术安全性提供帮助。     

基于SS-OCT分析眼轴长度与眼前节参数的相关性

目的:利用扫频源光相干断层扫描成像(SS-OCT)观察与探讨眼轴长度(AL)与眼前节相关参数的相关性。方法:横断面临床研究,纳入2022-01-01/03-31在郑州大学第一附属医院眼科门诊招募的不同程度近视的成人志愿者109例,依据AL将受检者分为4组：A组(AL≤24.0mm)、B组(24.0mm26.0mm)。SS-OCT(视微影像)进行眼前节检查,对中央角膜厚度(CCT)、晶状体厚度(LT),前房参数：中央前房深度(ACD)、前房宽度(ACW)、房角开放距离(AOD500)、房角隐窝面积(ARA500)、小梁网-虹膜间面积(TISA500)、小梁虹膜夹角(TIA500),晶状体矢高(CLR)进行记录,并分析其与AL、等效球镜度数(SE)的关系。结果:四组CCT比较无差异(P>0.05)。四组SE、LT、ACD、ACW、AOD500、ARA500、TISA500、TIA500、CLR比较有差异(均P<0.01)。SE、LT与AL呈负相关(r=-0.75、-0.41,均P&l...     

Gross anatomic evidence of partitioning in the human fibularis longus and brevis muscles

Evidence from a variety of studies suggests that many mammalian muscles are partitioned with respect to their architecture and innervation. Each of these specific muscle subvolumes is innervated by an individual muscle nerve branch, contains motor unit territories with a unique array of physiological attributes and has been known as a neuromuscular compartment or segment. This gross anatomic study investigated for evidence of neuromuscular segmentation in human fibularis (peroneus) longus and brevis muscles. Forty-three legs (24 left, 19 right) from embalmed adult cadavers were dissected. Any architectural segments within these muscles were identified. The specific innervation patterns of these muscles were also described. The fibularis longus muscle was consistently found to have connective tissue partitions that separated it into four parts: anterior superficial, anterior deep, posterior superficial, and posterior deep. The innervation pattern of this muscle was consistent with the segments defined by the connective tissue partitions. There were consistently four primary motor branches, each supplying a specific portion of the fibularis longus muscle. While a typical branching pattern was recognized, there was some variability as to the order of these branches as they originated. The fibularis brevis muscle was consistently found to have a central connective tissue partition that separated it into two portions: anterior and posterior. In 91% of the fibularis brevis muscles, there were two primary motor branches, one for each of the two segments of the muscle. In the other 9%, only one primary motor branch supplying the muscle could be identified. © 1996 Wiley-Liss, Inc.     

替格瑞洛联合急诊经皮冠状动脉介入治疗对ST段抬高型心肌梗死患者心肌损伤及血小板聚集程度的影响

目的 研究替格瑞洛联合急诊经皮冠状动脉介入(PCI)治疗对ST段抬高型心肌梗死(STEMI)患者心肌损伤、血小板聚集程度的影响.方法 选择接受PCI治疗的108例STEMI患者作为研究对象,采用随机数字表法分为替格瑞洛组和氯吡格雷组,分别接受PCI联合替格瑞洛治疗以及PCI联合氯吡格雷治疗.PCI术后评估心肌血流灌注情况,检测血清中心肌损伤指标以及血小板聚集指标.结果 PCI术后,替格瑞洛组患者的冠状动脉狭窄程度(TIMI)分级和心肌灌注(TMPG)分级均显著高于氯吡格雷组,校正TIMI帧计数(CTFC)以及无复流率均显著低于氯吡格雷组;PCI术后12h时,替格瑞洛组患者血清中肌酸激酶(CK)、肌酸激酶同工酶(CK-MB)、肌钙蛋白Ⅰ(cTnⅠ)、肌钙蛋白T(cTnT)、血小板活化因子(PAF)、血小板α颗粒膜蛋白-140(GMP-140)、血栓素B2(TXB2)的含量显著低于氯吡格雷组,6-酮-前列腺素F1α(6-keto-PGF1α)的含量显著高于氯吡格雷组.结论 急诊PCI围手术期应用替格瑞洛治疗STEMI能够更为有效的改善心肌血流灌注、减轻心肌细胞损伤、抑制血小板聚集.
