To date, the medium and long-term space flight is urgent in need and has become a major task of our manned space flight program. There is no doubt that medium and long-term space flight has serious damaging impact upon human physiological systems. For instance, atrophy of the lower limb anti-gravity muscle can be induced during the space flight. Muscle atrophy significantly affects the flight of astronauts in space. Most importantly, it influences the precise manipulation of the astronauts and their response capacity to emergencies on returning to the atmosphere from space. Muscle atrophy caused by weightlessness may also seriously disrupt the normal life and ＇work of the astronauts during the re-adaptation period. Here we summarize the corresponding research concentrating on weightlessness-induced changes of muscular structure and function. By combining research on muscle pain, which is a common clinical pain disease, we further provide a hypothesis concerning a dynamic feedback model of ＂weightlessness condition → muscular atrophy ←→ muscle pain＂. This may be useful to explore the neural mechanisms underlying the occurrence and development of muscular atrophy and muscle pain, through the key study of muscle spindle, and furthermore provide more effective therapy for clinical treatment.

目的探讨医源性胆管损伤和狭窄的类型、重建时机、促成损伤因素及胆道重建技术等对疗效的影响。方法回顾性分析了94例医源性胆管损伤患者,分为术中诊断、术后早期发现、引流或重建术后又出现狭窄等3组接受胆道再建手术。结果本组病例无手术死亡情况。术中诊断的31例中,22例系未辨清胆囊管和肝总管、胆总管联合部。随诊3-15年,疗效优者75例(79.8%),良者13例(13.8%),优良率达93.6%,差者6例(6.4%)。差者中已死亡5例(占5.3%,5/94)。结论除熟悉病理解剖关系外,经验和谨慎对预防医源性胆管损伤至关重要。胆道重建的疗效主要受Bismuth分型和胆道重建技术等因素的影响。

Vagus nerve stimulation(VNS)and stroke:Stroke is the second leading cause of death and the third leading cause of disability worldwide(Baig et al.,2023).There have been significant paradigm shifts in the management of acute ischemic stroke through mechanical *** chronic ischemic stroke,invasive VNS paired with rehabilitation is associated with a significant increase in upper limb motor recovery and is FDA-approved(Baig et al.,2023).There are no treatments of similar efficacy in acute intracerebral hemorrhage(ICH)where several promising trials,e.g.,TICH-2,STOP-AUST,and TRAIGE did not show improvements in functional outcomes(Puy et al.,2023).
