A one-year survey on the use of a powder from Rosa canina lito in acute exacerbations of chronic pain

This pilot surveillance included 152 patients with acute exacerbations of chronic pain, 124 (Back group) with non-specific low back pain (NSLBP), 20 with NSLBP overridden by osteoarthritic pain (Knee-Hip group), and eight with specific LBP (included in the safety analysis). Patients were recommended the rose hip and seed powder Litozin at a dose providing up to 3 mg of galactolipid/day for up to 54 weeks. Clinical symptoms and well-being were assessed every 6 weeks. The patients also kept a diary of their pain and the requirement for rescue medication. Data were analysed by intention to treat with last observation carried forward. Only 77 patients completed the year of surveillance. Multivariate analysis suggested an appreciable overall improvement during the surveillance, irrespective of group, and this was reflected for most of the individual measures in repeated measures ANOVA. The degree and time-course of improvement echoed that seen in similar surveillances of patients receiving an aqueous extract of Harpagophytum. Multiple regression analyses indicated that percentage changes from baseline tended to be greater in patients with greater degrees of pain and disability, but were otherwise largely unrelated to the patients' characteristics. There were no serious adverse events. The rose hip and seed powder, Litozin, seems to deserve further, more definitive studies as a possible option in long-term management of NSLBP with or without osteoarthritic pain.     

Shy-Drager综合征26例的临床分析

目的:探讨Shy-Drager综合征(SDS)的临床和辅助检查的特点,为临床诊断提供依据。方法:回顾性分析26例临床诊断为SDS患者的临床资料、头颅磁共振(MRI)、肛门括约肌肌电图(EAS-EMG)、校正QT间期和尿流动力学检查。结果:14例患者行头颅MRI检查,6例患者出现壳核T2低信号。19例患者行EAS-EMS检查,均有自发电位。13例患者行尿流动力学检查,9例有尿道流出梗阻现象。20例患者行心电图检查,平均校正QT间期达0.409 ms。结论:临床表现结合头颅MRI和EAS-EMG有助于提高SDS的诊断。     

Morel-Lavallée损伤诊疗进展

Morel-Lavallée(MLL)损伤是由剪切力等暴力使皮肤、皮下组织与深筋膜分离而引起的复杂的软组织闭合性撕脱损伤,疾病初期具有复杂性和隐蔽性,常因延迟诊断而导致感染、截肢、多器官衰竭甚至死亡等.目前,MLL的治疗尚无统一指南,需根据损伤情况及患者意愿综合考虑.在合并开放伤、骨折、神经血管肌腱损伤时,处理的优先顺...     

Study on Remote Field Eddy Current Testing Technology for Crack-like Defects in Long Truss Structure of Aircraft

Detection of hidden defects of aircraft long truss structures (aluminum alloy) is a challenging problem. The shape of the aircraft truss structure is complex, and the crack defects are buried in a large depth. Without the restriction of skin effect, remote field eddy current (RFEC) has great advantages in detecting buried depth defects. In this paper, in order to detect the hidden defects of the aluminum alloy aircraft long truss structure, the remote field eddy current probe is improved from two aspects of magnetic field enhancement and near-field signal suppression using the finite element method. The results show that indirect coupling energy is greatly enhanced when the connected magnetic circuit is added to the excitation coil. By adding a composite shielding structure outside the excitation coil and the detection coil, respectively, the direct coupling energy is effectively restrained. As a result, the size of the probe is reduced. By optimizing the coil spacing and probe placement position, the detection sensitivity of the probe is improved. The simulation is verified by experiments, and the experimental results are consistent with the simulation conclusions.     

BrainAGE and regional volumetric analysis of a Buddhist monk: a longitudinal MRI case study

ABSTRACT

Yongey Mingyur Rinpoche (YMR) is a Tibetan Buddhist monk, and renowned meditation practitioner and teacher who has spent an extraordinary number of hours of his life meditating. The brain-aging profile of this expert meditator in comparison to a control population was examined using a machine learning framework, which estimates “brain-age” from brain imaging. YMR’s brain-aging rate appeared slower than that of controls suggesting early maturation and delayed aging. At 41 years, his brain resembled that of a 33-year-old. Specific regional changes did not differentiate YMR from controls, suggesting that the brain-aging differences may arise from coordinated changes spread throughout the gray matter.     

多巴酚丁胺负荷核素心肌显像在冠心病诊断中的应用

目的 药物负荷核素心肌显像在冠心病诊断中的价值。方法 选取本院胸痛可疑冠心病，且能耐受平板运动试验的住院患者55例，进行多巴酚丁胺(DBA)负荷99m^Tc-MIBI门控心肌灌注断层显像(SPECT)，平板运动试验检查，部分行冠脉造影检查。结果DBA-SPECT结果40％(22／55)的患者DBA负荷SPECT结果呈可逆性放射性稀疏(即心肌缺血改变)。20例有冠脉造影对照的患者中，DBA负荷SPECT诊断冠心病的灵敏度87．5％(7／8)，特异性75％(9／12)，准确率80％(16／20)。结论DBA负荷SPECT是诊断冠心病的一种敏感性及特异性较高的非创伤性方法。
