Extrinsic Factors as Component Positions to Bone and Intrinsic Factors Affecting Postoperative Rotational Limb Alignment in Total Knee Arthroplasty

Background

This study aimed to identify the factors affecting postoperative rotational limb alignment of the tibia relative to the femur. We hypothesized that not only component positions but also several intrinsic factors were associated with postoperative rotational limb alignment.

Reliability,Surgeon Preferences,and Eye-Tracking Assessment of the Stress Examination of the Ankle Syndesmosis

The diagnosis and stabilization of ankle syndesmotic injuries after acute injury remains an area of controversy in the foot and ankle surgical literature, seemingly without universal consensus. The primary objective of this investigation was to determine the frequency of agreement and reliability of the stress examination of the ankle syndesmosis. Secondary objectives were to determine surgeon preferences and protocols with respect to the ankle syndesmosis and to use gaze recognition software to perform an eye-tracking assessment during performance of stress examinations. Twelve foot and ankle surgeons, 12 residents, and 12 students were shown 5 intraoperative fluoroscopic still images and videos of the stress examination of the ankle syndesmosis. They were asked to evaluate the result as being “positive” or “negative” for syndesmotic stability. The overall reliability of the interpretation of the stress examination of the ankle syndesmosis was a kappa of 0.123 (surgeons 0.087; residents 0.019; students 0.237), indicating “slight” agreement. Survey results indicated wide variability in the perioperative preferences and protocols of surgeons dealing with the evaluation and treatment of the ankle syndesmosis. Eye-tracking results also demonstrated variability in the anatomic structures of interest focused on during performance of this testing. The results of this investigation provide evidence of reliability well below what would be expected of a gold standard test during stress examination of the ankle syndesmosis. These results indicate that future scientific endeavors are required to standardize the performance and interpretation of this testing.

基于因子分析及二元Logistic回归分析探讨慢性咳嗽治法的用药规律

目的:探讨中医药治疗慢性咳嗽的用药规律。方法:选取2009年2月至2017年12月北京中医药大学东方医院呼吸热病科咳嗽专病门诊收治的慢性咳嗽患者641例作为研究对象,通过因子分析及二元Logistic回归总结常用药物组合与证型的关联性,从而获得慢性咳嗽的治法及用药规律。结果:慢性咳嗽治疗主以祛风宣肺为主,常用药物有炙麻黄、黄芩、前胡、厚朴、炙紫菀、炙款冬花、细辛、青风藤等;兼湿热郁肺者,佐以清热化湿,常用药有薏苡仁、佩兰、白豆蔻、广藿香等;兼有肺阳亏虚者,佐以温阳健脾,兼寒饮伏肺者,佐以温阳化饮,此2证常用药有白术、茯苓、桂枝、炙甘草、细辛等;兼有痰湿阻肺者,佐治以理气燥湿、化痰止咳,常用药有紫苏子、紫苏梗、炒白芥子、炒莱菔子等;兼肺阴亏虚者,佐治以养阴清热、润肺止咳,常用药有麦冬、芦根、白茅根等。结论:慢性咳嗽以祛风宣肺为基本治法;遣方用药须兼顾宣降共施,寒温并用,肺脾同治。     

从肝风入络探讨偏头痛相关缺血性卒中

偏头痛与卒中存在相关性,尤其是缺血性卒中。从中医学角度探讨偏头痛与缺血性卒中的相关性,认为偏头痛相关缺血性卒中病位在肝,急性期发病当责之气机逆乱,与肝密切相关,肝风入络为其核心病机,病久脑络瘀滞、脑髓失荣为其最终病理转归。     

经皮腔内冠状动脉成形术和旋磨术治疗冠心病的早期疗效和安全性比较

对40创经皮腔内冠状动脉成形术和10例经皮腔内冠状动脉旋磨术的早期疗效及安全性进行比较。结果发现经皮腔内冠状动脉成形术和旋磨术成功率分别为82．5％和80％;经立腔内冠状动脉成形术组46处病变经扩张后狭窄度由80％±14％降至20％±10％,经皮腔内冠状动脉旋磨术组17处病变经旋磨后狭窄度由84％±9％降至29％±2％,两组残余狭窄有显著性差别（P＜0．05）;经文腔内冠状动脉成形术和旋詹本并发症总发生率分别为17．5％和80％（P＜0．001）,重要并发症发生率为2．5％和50％（P＜0．001）,经皮腔内冠状动脉成形术组无死亡病例,放房本组死亡一例。由此认为,经皮腔内冠状动脉成形术疗效及安全性均高于经皮腔内冠状动脉旋废水,且适应症疗;经皮腔内冠状动脉旋磨术适用于某些“硬”病变或解剖类型不适合作经皮腔内冠状动脉成形术者,残余狭窄显著时需辅以经皮腔内冠状动脉成形术以提高疗效。
