Phacoemulsification,Intraocular Lens Implantation,Goniosynechialysis, and Pseudo-Pupilloplasty for Refractory Acute Primary Angle Closure with Atonic Dilated Pupil

ObjectiveTo evaluate the efficacy and safety of prompt phacoemulsification, intraocular lens implantation, visco-goniosynechialysis, combined with pseudo-pupilloplasty for refractory acute primary angle closure (APAC) with atonic dilated pupil and to describe a feasible method of pupilloplasty.MethodsA consecutive series of refractory APAC patients who had atonic dilated pupil and undergone prompt phacoemulsification combined with pseudo-pupilloplasty at our center were retrospectively analyzed. Pseudo-pupilloplasty referred to a method of pupilloplasty which included 4.5-mm capsulorhexis, postoperative opacification of anterior capsule residue, and ultimate pseudo-pupil formation. Preoperative and postoperative measurements included intraocular pressure (IOP), best corrected visual acuity (BCVA), and anterior chamber depth (ACD). Intraoperative and postoperative complications were documented. The process of pseudo-pupil formation was also observed.ResultsA total of 20 eyes of 19 APAC patients were followed up for 19.7 ± 9.8 months. IOP was lowered from preoperative 44.0 ± 9.8 mmHg to 15.5 ± 2.6 mmHg at final visit (t = 11.945, P < 0.001). ACD was deepened from preoperative 1.77 ± 0.21 mm to 3.40 ± 0.20 mm at final visit (t = –27.711, P < 0.001). Twelve of 20 eyes had residual angle synechiae, whereas only 3 eyes needed anti-glaucoma medications. No severe complication was observed. All eyes had pseudo-pupil gradually formed within 3 months, accompanied with the gradual improvement of BCVA from preoperative 1.18 ± 0.55 to 0.58 ± 0.22, 0.26 ± 0.09, 0.11 ± 0.09, and 0.11 ± 0.09 at postoperative day 1, month 1, month 3, and last visit.ConclusionsPrompt phacoemulsification-goniosynechialysis is effective and safe for refractory APAC with atonic dilated pupil. Pseudo-pupilloplasty is a feasible procedure for pupil reconstruction.     

A Case of Refractory Childhood Glaucoma Secondary to Weill-Marchesani Syndrome: Management with Combined CO2 Laser-Assisted Sclerectomy Surgery and Trabeculectomy

A 2-year-old girl was diagnosed as Weill-Marchesani syndrome with typical systemic features of short stature, short and stubby hands and feet, language disorders and mental retardation. He developed bilateral angle closure glaucoma, ectopia lentis and suffered visual loss from the ocular features of Weill-Marchesani syndrome. The child was successfully treated by combined CO₂ laser-assisted sclerectomy surgery and trabeculectomy.     

《针灸大成》关于气海穴临床应用的文献研究

目的:通过检索《针灸大成》中与气海穴治疗作用相关的文献条文,总结气海穴在治疗各系统疾病中运用频次较高的疾病及其配穴规律,为临床针灸对气海穴的使用提供理论支持。方法:以《中华医典》(第五版)中《针灸大成》作为文献检索来源,将气海穴及气海穴的别称“脖胦”“下肓”“丹田”“肓之原”“肓原”“下言”和“气泽”为检索词,用计算机检索工具及人工检索相结合的方法检索符合要求的文献条文,通过建立本研究的数据库,频次分析、条形统计图比较分析等方法,总结出气海穴在治疗各系统疾病中的运用频次及其配穴规律。结果:在《针灸大成》所涉及的条文中,气海穴尤善治疗内科疾病,在治疗内科疾病中排名前3位的是脾胃系病症、气血津液疾病、肾系病症和妇科疾病,气海穴配穴习惯为上下配穴法,同名经配穴法,以及前后配穴法,其中主要为前后配穴法和同名经配穴法。结论:气海穴《针灸大成》中单穴应用占比最高,而在气海穴众多配穴中,运用了本经配穴法、上下配穴法、前后配穴法,配穴归经主要来自任脉和足太阳膀胱经。同名经配穴法,同气相求,可增加疗效;与气海穴配伍较多的足太阳膀胱经以背腧穴为主,此为前后配穴法,亦称腹背阴阳配穴法,腹部为阴,腰背为阳,前后配穴法可起到“从阳引阴”亦可“从阴引阳”的作用,以达到调节阴阳,调和脏法,调畅经络的目的。     

试论异常毒性作为药品质量控制指标的合理性

异常毒性最初是一种确保复杂成分制剂生产工艺一致性及安全性的辅助检测手段，后来成为针对外源性毒性污染物的通用安全性检测项，曾在世界范围内被各国药典收载。由于该检测与药品质量、安全性之间的关联性受到质疑，各国药典逐渐在各论及通则中删除该检测项，目前仅《中国药典》保留异常毒性。由于该检测存在设定限值难以统一、给药体积及给药剂量不合理、结果易受干扰且缺乏明确的判定标准等试验原理及设计上的缺陷，导致其试验结果没有实际参考意义。基于对历史数据的回顾分析，国际监管机构及卫生组织对异常毒性有了更为科学的认知，并已逐渐形成统一的监管共识：严格的生产控制措施和有效的质量检测手段，比异常毒性检测更为重要；异常毒性检测结果或与产品质量及污染不具相关性；在异常毒性检查中使用大量动物不符合动物福利和“3R”原则。本文从科学角度试论异常毒性作为药品质量控制指标的合理性，并总结异常毒性修订的科学原则，希望能为我国监管机构、制药行业修订异常毒性相关内容提供思考角度。     

中医药治疗慢性前列腺炎研究概况

综述近年中医药治疗慢性前列腺炎的临床研究,认为本病病因病机之核心在于脾肾亏虚为本,湿热、痰浊、瘀毒为标,病久则伤及脾肾,由实转虚。中医内治法主要以辨证论治、辨病论治或单方验方为主,外治法以中药洗浴、中药灌肠、肛门给药、针灸为主。中医药治疗本病优势明显。应继续完善对中医药作用机制的认识,制订统一的辨证论治及疗效评价标准,针对效果显著的名方开展研究。
