目的 探讨剪切波弹性成像技术(SWE)量化评估颈椎屈曲不同角度斜方肌弹性模量的应用价值.方法 2018年10月至2019年1月于河南省洛阳正骨医院招募20名健康成年男性实习医师作为试验对象.在受试者颈椎屈曲0°和30°时,测试人员A和B分别使用SWE量化评估斜方肌上束剪切模量,5 d后测试者A进行重复评估.记录颈椎屈曲...     

岛状斜方肌肌皮瓣在口腔颌面外科中的应用

１９８５年４月至１９９３年７月应用岛状斜方肌肌皮瓣整复口腔颌面部缺损２３例，肌皮瓣面积最小６ｃｍ×４ｃｍ，最大１２ｃｍ×８ｃｍ，均获成功。我们对肌皮瓣血管蒂的选择、手术方法及其优缺点进行了讨论。     

骨骼肌最大收缩力与最适初长度及其参数的研究

本实验以免载体股直肌为实验模型,研究了该肌在一定脉冲电流刺激下其初长度与收缩力、肌张力及肌力变化的相互关系。同时测定了正常生理状态下兔伸屈膝时股直肌拉长度的变化。结果表明:兔股直肌延长在1.0cm内时,肌力随初长度的延长而增大,超过1.0cm时增大已不明显(p<0.0 1),1.0cm与股直肌的生理最大延长度1.1cm相似。说明兔股直肌的初长度变化不应超过生理最大延长度。而人的骨骼肌与哺乳动物的骨骼肌没有本质的区别,因此,人骨骼肌的初长度变化也不应超过生理最大延长度。肌腱转位后的活动范围应在原位的生理活动范围内,才能发挥最佳收缩效应。     

儿童尺侧腕屈肌的应用解剖

用72侧3岁左右的童尸上肢,对尺侧腕屈肌的位置、形态、动脉和神经进行了观测。肌腹的长、宽和厚分别为86.72±1.61mm、11.06±0.23mm和2.70±0.08mm。腱的长、宽和厚分别为27.05±0.25mm、2.78±0.06mm和1.19±0.03mm。动脉来源于尺侧返动脉和尺动脉,前者主要供应肌腹的上1/3,后者主要供应下2/3。尺神经在尺神经沟附近发出至该肌的分支,并从肌腹上1/4段的深面穿入肌内。还就其临床应用进行了讨论。     

雄性大白鼠球海绵体肌和坐骨海绵体肌的运动神经元—HRP法研究

本实验用HRP注射于大白鼠的一侧球海绵体肌和坐骨海绵体肌后,在脊髓腰骶段的不同平面可观察到支配该两肌的运动神经元胞体出现标记并具有一定的局部定位关系。支配球海绵体肌的运动神经元主要位于L_5～S_1的背内侧群,而支配坐骨海绵体肌的运动神经元主要位于背外侧群和腹侧群。本文认为大白鼠腰骶段前角背内侧群和背外侧群同腹外侧群细胞一样,同属于Onuf's核的同源神经细胞。本文还观察了大白鼠腰骶段脊髓前柱细胞的配布。     

Lymphocytic choriomeningitis in Michigan

We summarize the first reported case of acquired lymphocytic choriomeningitis virus (LCMV) infection in Michigan to be investigated by public health authorities and provide evidence of the focal nature of LCMV infection in domestic rodents. Results of serologic and virologic testing in rodents contrasted, and negative serologic test results should be confirmed by tissue testing.     

推拿治疗对膝骨关节炎患者股四头肌功能的影响

目的观察推拿手法治疗膝骨关节炎的临床疗效及其对患者股四头肌功能的影响。方法采用随机分组的方法将96例膝骨关节炎患者分为治疗组和对照组各48例,分别采用推拿手法治疗和口服芬必得治疗,疗程20天。观察临床疗效、Lequene＆Mery严重度指数、JOA评分及等速肌力测试结果变化情况。结果治疗组的总有效率为89.58%,对照组为87.5%（P〉0.05）;两组治疗后Lequene＆Mery严重度指数、JOA评分均明显改善（P〈0.05）,但两组间比较差异无统计学意义（P〉0.05）;治疗后两组患者股四头肌PT、TW、AP均明显增加（P〈0.05）,且治疗组的增加大于对照组（P〈0.05）。结论推拿治疗能改善膝骨关节炎患者症状,且能提高其股四头肌的肌力和做功等。     

The musculus pterygoïdeus proprius: an in-vivo approach with magnetic resonance imaging

There is a limited understanding of the normal function of the pterygoïdeus proprius muscle and the role that this muscle may have in temporomandibular disorders. Despite a well‐described anatomical in‐vitro approach to this muscle, there are still difficulties in investigating the fossa pterygopalatina. This study reveals an alternative in‐vivo approach by magnetic resonance imaging to visualise the muscle in the fossa pterygopalatina on 78 head halves, describe the connections with the musculus temporalis and pterygoïdeus lateralis as well as report the incidence without dealing with the known inconveniences of the dissection approach. The results show an incidence of 12.82% for the musculus pterygoïdeus proprius equally divided between both genders. Two different types of bridging between the musculus temporalis and musculus pterygoïdeus lateralis were also found: (i) ‘O’ shape (6.41%) and (ii) ‘Y’ shape (6.41%). This study suggests the use of magnetic resonance imaging to investigate the different connections between vascular and muscular structures in the fossa pterygopalatina. Further research with this approach to link the appearance of the muscle with neurovascular entrapment syndromes is warranted.
