蟾酥制剂与两种常用牙髓失活剂的细胞毒性比较

目的比较蟾酥制剂与多聚甲醛制剂和三氧化二砷制剂2种临床常用牙髓失活剂的细胞毒性。方法实验用细胞为1929细胞，采用四唑盐比色法观测。结果多聚甲醛制剂的细胞毒性最强，其次为蟾酥制剂，三氧化二砷制剂较弱。结论蟾酥制剂的细胞毒性介于多聚甲醛制剂和三氧化二砷制剂之间。     

门控心肌灌注显像对冠心病PCI后疗效评价

目的利用门控心肌灌注显像评价PCI的疗效。方法35例患者PCI术前1周及术后1～6个月均行门控心肌灌注显像,比较PCI前后血流灌注、室壁运动变化、LVEF的变化情况。结果冠心病患者PCI术后大部分患者的左室功能及血流灌注情况有明显的改善。结论门控心肌灌注显像在评价PCI手术的疗效方面有重要价值。     

常压及控制性降压下脊髓急性牵拉损伤比较研究

目的 评价控制性降压是否增加脊髓对牵拉损伤的易感性。材料与方法健康成年杂种犬6只，随机分为常压和控制性降压脊髓牵拉损伤组。观察常压及控制性降压水平下相同程度牵拉损伤后脊髓血流(SCBF)、体感诱发电位(SEP)、神经源性运动诱发电位(NMEP)改变的差异。结果 外周血有创动脉压(MABP)平均下降幅度为40．5％。经SSPS统计软件独立样本t检验，不同牵拉水平下，常压组及低压组的SCBF(％)、SEP波幅(Asep)(％)及NMEP波幅(％)无显著差异。结论 尼卡地平控制性降压不增加脊髓对牵拉损伤的易感性。     

我国足踝外科的再思考

12例心脏锐器伤的诊断与治疗

心脏锐器伤病情危重，如致心脏破裂死亡率高，仅有少数患者能及时地被转送到医院急救。李良彬等报道，入院前死亡率达80％，及时地诊断和手术可使80～90％的伤者获救，现将1995年2月至2004年1月救治12例心脏锐器伤的体会报道如下。     

老年人趾甲真菌病易感因素分析

目的 探讨老年人趾甲真菌病的易感因素. 方法 收集2005-2007年,我院60岁以上老年趾甲真菌病患者100例为病例组,同时收集60岁以上老年非真菌感染趾甲病患者100例为对照组,对两组患者的临床资料进行分析比较. 结果 病例组100例患者中,并存糖尿病24例,占甲真菌病并存疾病的首位,对照组并存糖尿病仅为6例,两组比较差异有统计学意义(χ2=12.706,P<0.05).病例组与对照组比较,下肢静脉曲张分别为31例和12例(χ2=10.695,P<0.05),足部畸形为36例和19例(χ2=7.248,P<0.05),趾甲外伤史为11例和3例(χ2=4.916,P<0.05),长期穿紧鞋史32例和12例(χ2=22.831,P<0.05),差异均有统计学意义.病例组47例女性患者中有12例既往有长期穿高跟鞋史. 结论 趾甲损伤、足部畸形、静脉曲张及糖尿病是趾甲真菌病的主要易感因素.     

Surgical strategy of one stage surgery of anterior release combined with posterior correction in treatment of severe scoliosis

Objective: Severe scoliosis refers to scoliosis with serious and stiff curve. It always combins with trunk imbalance in coronal and sagittal contour. Besides complex pathological changes, cardiopulmonary deficits and other concomitant diseases increase treatmental difficulties. So the treatment of severe scoliosis is always a great challenge to spine surgeon. Methods :Thirty-six patients with severe scoliosis received one stage posterior correction followed by anterior release during July 1997 to January 2003, including 9 males and 27 females. Mean age was 17.2 years. Of them, 33 was idiopathic scoliosis and 3 was neurofibromatosis scoliosis( Cobb angle: 85-116 degree); 20 cases were abnormal in sagital plane. Three-dimensional devised instrumentation were applied such as CD, CD-Horizon, TSRH or Isola in posterior procedure followed by anterior release during the same anesthesia. 31 cases of this group received thorac icplasty. Results: The correction in the frontal plane achieved an average of 48.5%. In the sagittal plane, the pathological shape of the spine was reduced and distinctly ameliorated. 80. 6% of the patients maintained or achieved balance of sagittal plane. There were no complications of severe neurological deficit, hook displacement, rod broken, and deep infection at follow-up. One case occurred traumatic pleurisy after operation and another appeared pseudarthrosis 2 years later. One case demonstrated imbalance 11 months after operation. One patient was presented loss of correction more than 10 degree at one year follow-up and 5.2 degree in average. Conclusion:The study indicates that the one stage posterior correction combined with anterior release in treatment of severe scoliosis can achieve satisfactory correction. Appropriate choice of cases, preoperational detailed assessment and application of SEP and wake-up test during operation can possibly reduce severe complication. The long-term outcomes still need further observation.     

STYLOID PROCESS SYNDROME LENGTFI AND PALPATION OF THE STYLOLD PROCESS

In 1980, 267 patients with related symp- toms were examined by tomography in our hos- pital. Among them the styloid process (SP) of 128 cases were 30 mm or more in length. Pha- ryngeal palpation was performed in 98. The SPs of 61 patients were palpable and tender. Diagno- sis was based on the related symptoms, tomogra- phy, positive pharyngeal palpation and SP tender- ness. Tomography showed that the longest SP was 75 mm, while the longest one with symptoms was 65 mm. The medial angulations of the SPs were from 100 t0 27° and the anterior angulations from 300 t0 50°.
