Three-dimensional finite element analysis of intramedullary nail with different materials in the treatment of intertrochanteric fractures

Intramedullary nails are the common treatment options for femoral intertrochanteric fractures. However, aseptic loosening is considered to be one of the primary forms of failure that can be caused by the stress shielding between the bone and implants. The matching in mechanical properties of implant and bone is a key issue to prevent this failure. Polyetheretherketone (PEEK) and Function-graded (FG) materials are widely used in clinical because of their excellent mechanical properties. In this study, to investigate the biomechanical behaviors of intramedullary nails made of Ti-6Al-4V alloy, Stainless Steel (SS), PEEK and two FG materials, three-dimensional finite element models of intertrochanteric fracture femur with intramedullary nail were constructed with ABAQUS. The maximum von Mises stress on the femoral fracture surface fixed by PEEK intramedullary nail was the largest, followed by FG intramedullary nail, which help stimulate bone growth and subsequently reduce fracture healing time. Compared with traditional metal intramedullary nails, PEEK and FG implants might increase von Mises stress along the same path in the proximal femur. The results showed that PEEK and FG intramedullary nails obviously changed the stress distributions in the bone and reduced stress shielding. This finding indicated that PEEK and FG intramedullary nails have the potential to become alternatives to the conventional metal intramedullary nails.     

国医大师王琦教授中医体质学理论在疼痛性疾病诊疗中的临床应用

慢性疼痛涉及临床各科的多种疾病，包括一些重大疾病和疑难疾病。中医体质学是中医学的新兴学科，其体质分类、体病相关思想以及“辨体论治”的诊疗方法已广泛应用到临床各科疾病的诊疗中。文章探讨了以中医体质学思想指导疼痛性疾病诊疗的若干理论问题，认为疼痛性疾病的发生与患者体质类型存在密切的关系。因此，在临床辨治疼痛性疾病时要考虑患者体质因素。所施方药不仅要符合病证特点，也要针对患者体质类型。并列举国医大师王琦教授辨体论治慢性前列腺炎盆腔疼痛综合征、偏头痛、过敏性头痛等疼痛性疾病的案例加以分析，以期为相关领域同仁提供参考。     

针刺辅助治疗难治性肠易激综合征临床试验方案关键点设计的思考＊

肠易激综合征（Irritable bowel syndrome，IBS）是临床常见病、多发病，其治疗方法丰富，但部分患者疗效欠佳，发展成难治性IBS。目前国内外关于针灸治疗难治性IBS的临床随机对照试验尚不多见。本文立足试验方案设计的“PICOS”原则，从研究对象及诊断标准、干预措施、对照措施、结局指标四个方面入手，重点探讨针刺辅助治疗难治性肠易激综合征临床试验设计的关键要点。从选择特色优势病种、明确诊断标准、制定符合临床实际的干预方案、运用符合目标的安慰针刺、结合研究设计和目的选定结局指标几个角度，阐述试验相关环节设计的原因和思考。     

Safety and efficacy of oral nemonoxacin versus levofloxacin in treatment of community-acquired pneumonia: A phase 3, multicenter,randomized, double-blind,double-dummy,active-controlled,non-inferiority trial

Background/Purpose

Nemonoxacin is a novel nonfluorinated quinolone with excellent in vitro activity against most pathogens in community-acquired pneumonia (CAP), especially Gram-positive isolates. The purpose of this study was to assess the efficacy and safety of nemonoxacin compared with levofloxacin in patients with CAP.

基于复杂网络的《新针灸学》与《经络腧穴学》比较分析研究（英文）

提取《新针灸学》《经络腧穴学》中穴位名称、主治病症信息,基于复杂网络建立穴-症网络,分析两者穴位数量、相互关联程度及主治规律变化,借助拓扑学数据解释变化原因,为传统针灸知识体系的结构化、标准化研究提供具体思路和方法。共纳入《新针灸学》386穴、773种症状、形成152163个穴位配伍对,《经络腧穴学》403穴、253种症状、28755个穴位配伍对。两本教材的穴-症网络存在丰富的差异性,其所载的病症结构化程度随医学知识的更新而提升。《新针灸学》模型具有更加典型的小世界效应,或因其以病症为主要分类手段的优势体现。两本教材穴位定位与主治方面发生许多变化,学科发展、时代背景等方面是变化的主要原因。     

Acupoint stimulation for long COVID: A promising intervention: 穴位刺激治疗长新冠:一种有前景的干预措施

“Long COVID” is a sustained symptom following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). According to recent statistics, at least 65 million people have long COVID, which poses a long-term threat to human health. The pathogenic mechanisms of coronavirus disease 2019 (COVID-19) are complex and affect multiple organs and systems. Common symptoms include palpitations, breathing difficulties, attention and memory deficits, fatigue, anxiety, and depression. It is difficult to achieve satisfactory treatment effect with a single intervention. Currently, treatment strategies for long COVID are still in the exploratory stage, and there is an urgent need to find appropriate and effective methods for long COVID treatment. Traditional Chinese medicine is effective in treating the various phases of COVID-19. Previous studies have shown that acupoint stimulation therapy is effective in improving palpitations, dyspnea, cognitive impairment, anxiety, depression, and other symptoms in patients. According to previous studies, acupoint stimulation may improve various symptoms related to long COVID. This paper discusses the potential application value of acupoint stimulation in the treatment of long COVID-related symptoms, based on the common sequelae of various systems involved in long COVID, and the effect of acupoint stimulation in the treatment of similar symptoms and diseases in recent years.
