枕骨蛛网膜颗粒隐窝的影像诊断

目的:探讨枕骨蛛网膜颗粒隐窝的CT、MR表现及其诊断价值.方法:回顾性分析1996年以来收治的23例枕骨蛛网膜颗粒隐窝的CT及MR影像特点.结果:23例枕骨蛛网膜颗粒隐窝均位于枕骨粗隆下方,CT表现为穿凿样骨质缺损,深达板障或外板,境界清锐.骨质缺损区横径为7～30 mm(最大者为双侧对称性生长,各侧均为25 mm×30 mm).8例MR显示内部信号均匀、且在各个序列上与脑脊液信号一致.3例钆喷替酸葡甲胺(Gd-DTPA)增强后均未见病灶强化.结论:蛛网膜颗粒隐窝是一种正常变异,通常与临床表现无关,有影像学特征表现.认识其CT、MR特征表现对与枕骨破坏性病变的鉴别非常重要.     

膝关节军事训练性骨挫伤的MRI表现及临床意义

【目的】初步探讨膝关节军事训练性骨挫伤的MRI影像学表现及其临床意义。【方法】对87例X线或CT检查结果为阴性的军事训练性膝关节损伤患者进行MRI检查。根据骨挫伤的分布及其损伤机制,将81例确诊为膝关节骨挫伤的患者分为轴移型损伤、仪表盘型损伤、过伸型损伤、夹击型损伤及髌骨外侧脱位等五型。【结果】骨挫伤的MRI表现为片状地图样异常信号影,边界不清。PDWI上表现为低信号、T2WI上表现为高信号;在PDWI或T2WI脂肪抑制序列上表现为高信号。81例MRI确诊为骨挫伤的患者中轴移性损伤32例,仪表盘式损伤18例,过伸型损伤11例,夹击式损伤13例,髌骨外侧脱位7例。【结论】MRI能够准确显示膝关节军事训练性骨挫伤的部位、范围及其附属结构的损伤。通过对骨挫伤进行分类,可以推断其损伤机制,并且能够为推测其附属结构损伤提供线索。     

Relation of pale tongue, purple tongue and TXA2-PGI2 regulation system

This paper analysed the relationship between pale tongue, purplish tongue and TXB2, 6-keto-PGF1 alpha levels in plasma of 70 cases with coronary heart disease (CHD) and 45 normal subjects. The results showed the following characteristics: The pale tongue group (217.76 +/- 30.5 pg/ml) showed no significant difference in TXB2 level compared with the normal group (164.49 +/- 10.85 pg/ml, P greater than 0.05), while both showed significant difference compared with the purplish tongue group (360.1 +/- 31.3 pg/ml) and that with purple spots (485.07 +/- 106.1 pg/ml, P less than 0.01). The pale tongue group (179.29 +/- 9.08 pg/ml) showed a significant difference in 6-keto-PGF1 alpha level compared with the normal group (244 +/- 19.31 pg/ml, P less than 0.01), but it showed no significant difference compared with the purplish tongue group (185.08 +/- 17.07 pg/ml) and that with purple spots (229.3 +/- 33.2 pg/ml, P greater than 0.05). The comparison between the groups of purplish tongue and that with purple spots and the normal group showed no significant difference (P greater than 0.05). The pale tongue group (1.33 +/- 0.18) showed a marked difference in TXB2/6-keto-PGF1 alpha ratio compared with the normal group (0.72 +/- 0.04, P less than 0.01), the purplish tongue group (2.12 +/- 0.22, P less than 0.01) and that with purple spots (2.25 +/- 0.55, P less than 0.05). The purplish tongue group and that with purple spots showed significant difference compared with the normal group (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)     

振动疗法对骨质疏松骨折患者骨矿含量、骨钙素及骨折愈合的影响

目的 研究振动疗法对骨质疏松骨折患者骨矿含量、骨钙素及骨折愈合的影响。方法选取2018年1月—2021年5月苏州大学附属第一医院和苏州明基医院康复医学科收治的60例骨质疏松性椎体压缩性骨折(OVCF)患者为研究对象,按照随机数字表法分为观察组和对照组,每组30例。患者入院后均行经皮椎体成形术治疗。对照组术后口服碳酸钙(600 mg/d)与强骨胶囊(2粒/次,3次/d);观察组在对照组基础上给予振动疗法。两组均治疗6个月。比较两组患者临床疗效,比较两组患者治疗前后骨密度、甲状旁腺素(PTH)、25-羟维生素D₃[25(OH)D₃]、骨钙素(BGP)、骨碱性磷酸酶(BALP)、Ⅰ型前胶原羧基端肽(PICP)、抗酒石酸酸性磷酸酶(TRAP)、视觉模拟评分法(VAS)、Fugel-Meyer运动功能评估量表(FMAS)、Barthel指数、骨痂生长评分的差值。两组均随访6个月,记录随访期间两组患者跌倒、再次骨折及并发症发生率。结果 观察组临床疗效优良率高于对照组(P<0.05)。观察组治疗前后腰椎、股骨颈、大转子、全髋的骨密度差值高于对照组(P...

舌体对舌力介导器的静息压力分析

目的:探讨坐位静息状态下舌肌对不同矢状向和垂直向位置舌力介导器的压力,以初步探索舌力介导器作为一种支抗方式的效用范围. 方法:纳入19例个别正常牙合志愿者(男4名,女15名,年龄23~33岁) ,分别个体化制作舌力介导器,矢状向测量选取正中线上对应于第二前磨牙远中、第一磨牙远中和第二磨牙远中3个部位,垂直向测量以舌位记录为参考零点,分别测量-3 mm、0 mm和3 mm这3个高度对应于第一磨牙远中处的压力. 所用传感器型号为美国Honeywell公司生产的FSS1500NS,压力校验仪、监测仪以及分析软件由厦门福芯微电子科技有限公司设计制作. 志愿者取坐位,测量舌体处于自然放松状态时的静息压力. 使用Friedman test对矢状向及垂直向各组数据进行多样本比较的秩和检验,P<0. 05为差异有统计学意义. 结果:在垂直向上,随着舌力介导器高度增加,压力逐渐增大(P<0. 001),-3 mm、0 mm和3 mm高度的压力均值分别为105. 83 Pa、167. 75 Pa和254. 25 Pa. 在矢状向上,压力由近中至远中逐渐减小(P<0. 001),其均值分别为177. 64 Pa、126. 72 Pa和109. 37 Pa. 结论:舌肌在静息状态下对舌力介导器的压力随基托高度增加而增大,并且由近中至远中逐渐减小,但在实际应用时应综合考虑效果和舒适度,不宜过高和偏远中.     

Autoamputation of the tongue

Autoamputation is an uncommon phenomenon that has been reported for the fingers, toes, appendix, ovary, spleen, etc. Autoamputation of the tongue has never been reported. An elderly man with carcinoma of lateral pharyngeal wall and tonsil presented with an autoamputated tongue that was attached to the oral cavity with a thin band. The patient required detachment of the tongue and tracheostomy followed by radiotherapy for the primary tumour.     

Relation of tongue color changes and red-cell immune adherence activity in patients with malignant bone tumor

This article presents that preliminary study on the changes of the tongue colour and the red-cell immune adherence (RCIA) activity in 40 patients with malignant bone tumor, as compared with 40 healthy persons. The results showed that the rate of erythrocyte C3b receptor yeast rosette were no statistically significant different between the pink and the crimson tongues in the bone tumor group and control group (P greater than 0.05). It appeared RCIA activity was no depression in the patients with malignant bone tumor during pink and crimson tongue. In the bone tumor group with the pale and the cyanotic tongues, the rate of erythrocyte C3b receptor yeast rosette and erythrocyte immune complex rosette was significantly lower than that of the control group (P less than 0.05, P less than 0.01). It appeared that RCIA activity in these patients was markedly impaired. The authors suggested that the tongue colour changes in the patients with malignant bone tumors could roughly reflect the level of RCIA activity. This phenomenon is beneficially to predict the body capacity against the malignant tumor.
