半规管阻塞术与迷路切除术治疗70例晚期顽固性梅尼埃病的疗效

目的 比较半规管阻塞术与迷路切除术治疗晚期顽固性梅尼埃病的远期疗效。 方法 回顾性分析2015年3月至2016年3月接受半规管阻塞术(n=56)和迷路切除术(n=14)治疗的70例晚期顽固性梅尼埃病患者的临床资料,比较半规管阻塞术(半规管阻塞术组)和迷路切除术(迷路切除术组)两种手术方式的治疗效果。 结果 半规管阻塞术组眩晕总控制率为96.4%(54/56),其中A级控晕率为80.4%(45/56)、B级控晕率为16.1%(9/56);迷路切除组眩晕总控制率为100%(14/14),所有患者均为A级控制;两组眩晕控制有效率差异无统计学意义(P>0.05)。半规管阻塞术组听力下降率为28.6%(16/56),迷路切除组听力损失率为100%(14/14),半规管阻塞术组听力损失率低于迷路切除组(P<0.001)。半规管手术组手术前、后颈源性/眼源性前庭肌源性电位(c/oVEMP)的异常率差异无统计学意义(P均>0.05)。迷路切除术组手术前、后颈源性/眼源性前庭肌源性电位的异常率差异有统计学意义(P=0.014;P=0.006)。半规管阻塞术组、迷路切除组的平衡恢复时间分别为(16.5±5.19)d、(25.07±7.87)d,差异有统计学意义(P<0.001)。 结论 半规管阻塞术治疗晚期顽固性梅尼埃病的疗效优于迷路切除术。

镇眩汤对梅尼埃病大鼠血管加压素的影响

目的探讨中药复方镇眩汤治疗梅尼埃病的机制。方法采用阻塞前庭导水管的方法复制梅尼埃病模型,观察大鼠用药前后听觉诱发电位听阈的变化及大鼠血浆中血管加压素的含量。结果与假手术组比较,模型组大鼠听觉诱发电位听阈和血浆血管加压素水平显著升高;与模型组比较,镇眩汤高、中剂量组大鼠听阈和血管加压管水平显著降低(P<0.05)。结论镇眩汤治疗梅尼埃病的机制与其调节血浆血管加压素有关。

Réingénierie des activités des services de biochimie et d'hématologie : Étude d'application aux activités de garde et de pré-analytiqueReengineering of Biochemistry and Haemotology services activity

French hospitals are confronted to more and more economic restrictions, aiming at reducing Health expenses. Care centers involved laboratories to counter this limitation, since these departments are expensive, althought they are essentials. Reorganization of the laboratories, pooling of their activities, automation and computerization increase was implemented in some establishments. Environment regulations required persons in charge to conceive new organization to deal with. Lariboisière—Fernand Widal group hospital wishes to set up such a project, within the framework of a restructuration of its medical and technical platform. For this, medical duty activities will be gathered and the pre-analytical phase of the biochemistry and hematology laboratories will be automated.     

泽泻汤组分不同配比对豚鼠膜迷路积水影响的比较

目的:观察泽泻汤中泽泻与白术不同剂量配比对膜迷路积水豚鼠的影响。方法:采用腹腔注射醋酸去氨加压素法复制膜迷路积水动物模型。观察各组豚鼠的行为学变化及蜗管组织病理学改变,计算各组豚鼠蜗管横截面积与蜗管加前庭面积之和(总面积)的比值,以评价膜迷路积水的程度。结果:与空白组比较,模型组豚鼠蜗管横截面积与总面积的比值明显升高(P<0.05);与模型组比较,3组实验组豚鼠蜗管横截面积与总面积的比值均下降,但实验1组与模型组比较差异有统计学意义(P<0.05)。结论:3组实验组中,以原方剂量配比(泽泻∶白术为5∶2)的实验1组缓解豚鼠膜迷路积水作用最佳,证实了仲景方剂配伍的科学合理性。     

Oro-maxillofacial bone tissue engineering combining biomaterials, stem cells, and gene therapy

Improvements have been made in regenerative medicine, due to the development of tissue engineering and cellular therapy. Bone regeneration is an ambitious project, leading to many applications involving skull, maxillofacial, and orthopaedic surgery. Scaffolds, stem cells, and signals support bone tissue engineering. The scaffold physical and chemical properties promote cell invasion, guide their differentiation, and enable signal transmission. Scaffold may be inorganic or organic. Their conception was improved by the use of new techniques: self-assembled nanofibres, electrospinning, solution-phase separation, micropatterned hydrogels, bioprinting, and rapid prototyping. Cellular biology processes allow us to choose between embryonic stem cells or adult stem cells for regenerative medicine. Finally, communication between cells and their environment is essential; they use various signals to do so. The study of signals and their transmission led to the discovery and the use of Bone Morphogenetic Protein (BMP). The development of cellular therapy led to the emergence of a specific field: gene therapy. It relies on viral vectors, which include: retroviruses, adenoviruses and adeno-associated vectors (AAV). Non-viral vectors include plasmids and lipoplex. Some BMP genes have successfully been transfected. The ability to control transfected cells and the capacity to combine and transfect many genes involved in osseous healing will improve gene therapy.     

Morel-Lavallée损伤的临床病理特点及治疗现状

Morel-Lavallée损伤是一类严重的闭合性软组织脱套伤,常见于高能量剪切暴力损伤,可发生在身体不同部位,经常伴随骨盆、髋臼等各类骨折的发生。尽管该损伤发生率不高,但这类损伤十分特殊,早期隐蔽性较强。临床外科医师对此类损伤缺乏足够的重视,往往处理不及时或处理不当,导致皮肤软组织坏死、感染等诸多并发症。目前,Morel-Lavallée损伤没有标准的分类系统,主要基于MRI影像学表现,但对于指导临床治疗及预后无实际意义。其治疗方案多样,如局部加压包扎、经皮穿刺抽吸、有限切开清创冲洗、负压吸引、置管引流等,效果不一。就Morel-Lavallée损伤的研究现状予以综述。     

Analysis of asbestos bodies and nude fibres in the lung parenchyma of operated lung cancers. A retrospective monocentric study of 73 cases

We report on a study concerning a retrospective monocentric series of 73 lung cancers operated on between July 2004 and December 2009. All patients had a mineralogical analysis of a sample of lung tissue combined with an occupational questionnaire. This combination enables us to suggest a declaration of occupational exposure in almost one third of cases. We suggest that a healthy parenchymal fragment is to be obtained by biopsy routinely in cases of lung cancer surgery. The analysis should be carried out if the occupational survey does not demonstrate any evident exposure and if the patient is not known to be presenting a pleuropulmonary disease following asbestos exposure (pleural plaques and asbestosis).
