| 1 | T1ρ/T2 mapping and histopathology of degenerative cartilage in advanced knee osteoarthritis显示文摘AIM To investigate whether normal thickness cartilage in osteoarthritic knees demonstrate depletion of proteoglycan or collagen content compared to healthy knees.METHODS Magnetic resonance(MR) images were acquired from5 subjects scheduled for total knee arthroplasty(TKA)(mean age 70 years) and 20 young healthy control subjects without knee pain(mean age 28.9 years). MR images of T1ρ mapping, T2 mapping, and fat suppressed proton-density weighted sequences were obtained.Following TKA each condyle was divided into 4 parts(distal medial, posterior medial, distal lateral, posterior lateral) for cartilage analysis. Twenty specimens(bone and cartilage blocks) were examined. For each joint,the degree and extent of cartilage destruction was determined using the Osteoarthritis Research Society International cartilage histopathology assessment system.In magnetic resonance imaging(MRI) analysis, 2 readers performed cartilage segmentation for T1ρ/T2 values and cartilage thickness measurement.RESULTS Eleven areas in MRI including normal or near normal cartilage thickness were selected. The corresponding histopathological sections demonstrated mild to moderate osteoarthritis(OA). There was no significant difference in cartilage thickness in MRI between control and advanced OA samples [medial distal condyle, P = 0.461;medial posterior condyle(MPC), P = 0.352; lateral distal condyle, P = 0.654; lateral posterior condyle, P = 0.550],suggesting arthritic specimens were morphologically similar to normal or early staged degenerative cartilage.Cartilage T2 and T1ρ values from the MPC were significantly higher among the patients with advanced OA(P= 0.043). For remaining condylar samples there was no statistical difference in T2 and T1ρ values between cases and controls but there was a trend towards higher values in advanced OA patients. CONCLUSION Though cartilage is morphologically normal or near normal, degenerative changes exist in advanced OA patients. These changes can be detected with T2 and T1ρ MRI techniques. | Benjamin S Kester Philip M Carpenter Hon J Yu Taiki Nozaki Yasuhito Kaneko Hiroshi Yoshioka Ran Schwarzkopf | 2017 | World Journal of Orthopedics2017，8，4： | 12 |
| 2 | 徒手肌力测试在工作相关性上肢不适征诊断中的应用显示文摘工作相关性上肢不适征通常表现为疼痛、无力、麻木(或刺痛)等三种神经性症状,这表明与周围神经病损有关。因此,相应的体格检查应该能够识别(或排除)是否存在神经功能损伤。本文提出了一种新的体格检查方法,此方法基于公认的经典模式,即周围神经损伤会导致其所支配的肌肉力量减弱。大部分上肢疼痛患者和存在职业性暴露的上肢疼痛患者通过上肢神经检查可以准确的诊断和定位神经痛,但这种检查方法相对复杂和费时。因此在经典方法的基础上提出了一种相对简单快速的检查方法,即对三组拮抗肌(胸部三角肌-后三角肌、肱二头肌-肱三头肌、桡侧腕屈肌-桡侧腕短伸肌)和三块单独的肌肉(尺侧腕伸肌、拇短展肌、小指展肌)进行简单快速检查的方法。临床医生可以通过这种体检,对周围神经的疼痛进行定位以确定疾病类型。大部分工作相关性上肢不适征都会表现出这些疼痛模式,但由于缺乏相应的诊断标准,传统的体检不能明确这些异常,而被列入'非特异性'疾病。建议将这9块肌肉的检查纳入到常规上肢体检中。 | JΦrgen Riis Jepsen Carl-Gran Hagert 杨凤 贾晓东 | 2012 | 环境与职业医学2012，29，12： | 2 |
| 3 | Tooth loss and alveolar remodeling in Sinosaurus triassicus (Dinosauria: Theropoda) from the Lower Jurassic strata of the Lufeng Basin, China显示文摘Pathological or traumatic loss of teeth often results in the resorption and remodeling of the affected alveoli in mammals. However, instances of alveolar remodeling in reptiles are rare. A remodeled alveolus in the maxilla of the Chinese theropod Sinosaurus (Lower Jurassic Lower Lufeng Formation) is the first confirmed example of such dental pathology in a dinosaur. Given the known relationship between feeding behavior and tooth damage in theropods (teeth with spalled enamel, tooth crowns embedded in bone) and the absence of dentary, maxillary, and premaxillary osteomyelitis, traumatic loss of a tooth is most likely the cause of alveolar remodeling. Based on the extent of remodeling, the injury and subsequent tooth loss were non-fatal in this individual. | XING LiDa BELL Phil R ROTHSCHILD Bruce M RAN Hao ZHANG JianPing DONG ZhiMing ZHANG Wei CURRIE Philip J | 2013 | Chinese Science Bulletin2013，58，16： | 2 |
