细胞因子与骨性关节炎软骨退变的研究现状

骨性关节炎是最常见关节疾患之一,是导致中老年残疾的最常见原因,严重危害着中老年人的生活质量。骨性关节炎的主要病理是软骨的改变,软骨细胞分解和合成活动的平衡有助于维持软骨细胞外基质结构和功能的完整性,而软骨细胞的这种平衡受到细胞因子制约,本文就近年来细胞因子与OA软骨退变之间的研究现状综述。

计算机导航辅助椎弓根螺钉固定的临床研究

目的椎弓根螺钉固定是脊柱病变切除后稳定性重建的标准方法。常规术中透视监测行颈胸节段椎弓根螺钉固定具有相当挑战性,本文旨在就计算机导航辅助椎弓根螺钉固定技术进行初步分析。方法2005年1月至2006年3月在计算机导航系统辅助下,对21例患者（年龄17～63岁,平均43．4岁）共行102枚椎弓根螺钉固定。术前采用0．75mm薄层螺旋CT数据扫描并导入计算机工作站进行脊柱三维重建;术中进行工具注册和匹配后对椎弓根螺钉固定进行实时显示。术后所有病例均采用CT和X线平片随访监测效果。结果手术顺利,螺钉大小选择合适,102枚椎弓根螺钉中100枚螺钉（98%）固定位置及方向准确,2枚椎弓根螺钉突破椎弓根外壁距离小于2mm。所有操作均未发生血管和神经损伤并发症。术中透视次数及手术室人员所受X线辐射量明显减少。结论计算机导航辅助椎弓根螺钉固定是一项安全的手术,且手术精度高。

介入化疗结合立体适形放射治疗晚期胰腺癌的临床观察

探讨晚期胰腺癌的介入化疗加立体适形放射治疗的临床疗效。先选择性胰腺动脉化疗,药物:CF 300 mg、5-FU 1 000~1 500 mg、DDP 60~80 mg和健择1.2~2.0 g,共4次。介入化疗后或两次介入之间行立体定向放射治疗,放疗采用4~6个适形野,总剂量为35~45 Gy,4~8 Gy/次,每周3次,21例患者CR率42.85%(9/21),PR率42.85%(9/21),SD 4.76%(1/21),PD 9.52%(2/21),总有效率(CR PR)85.70%(18/21)。初步研究结果提示,主观指标评估,2例临床症状完全消失,17例主观症状有所改善。介入化疗结合立体放射治疗晚期胰腺癌不失为临床选用的治疗手段。     

Effect of electro-acupuncture combined with early rehabilitation on motor function and expressions of CD11b/CD18 and tumor necrosis factor-α in patients with acute cerebral infarction

Objective To observe the effect of electro-acupuncture combined with early rehabilitation on the motor function and expressions of the adhesion molecules CD11b and CD18 in the polymorphonuclear leucocytes (PMN) and monocytes and serum tumor necrosis factor-α (TNF-α) levels in patients with acute cerebral infarction (ACI). Methods A total of 165 ACI patients were randomly divided into control group (group A, n=50), conventional rehabilitation group (group B, n=50) and comprehensive rehabilitation group (group C, n=65). The expressions of CD11b and CD18 in the PMN and monocytes and serum TNF-α levels were determined before and at 1, 2, and 4 weeks after the treatment. Thirty-two healthy subjects were also recruited as the normal control group (group N). The neurological function of the subjects was evaluated by modified Edinburgh-Scandinavia stroke scale (MESSS) and Fugi-Meyer Assessment (FMA), and their activity of daily living (ADL) was assessed using Barthel index (BI). Results The CD11b/CD18 expression in the PMN and MN and serum TNF-α level in groups A, B and C were significantly higher than those in group N before and 1 week after the treatment (P<0.05). CD11b/CD18 expression and serum TNF-α level were significantly lower in groups B and C than in the group A at 1 week after the treatment, and significantly lower in group C than in group B (P<0.05). At 2 weeks of treatment, CD11b/CD18 and TNF-α were significantly lower in groups B and C than in the group A, being the lowest in group C (P<0.05). The scores of mESSS in both groups B and C were lower than that in group A, and the scores were lower in group C than in group B. Group C showed higher FMA scores than group B, both having higher scores than group A. At 4 weeks of treatment, the mESSS scores were significantly lower, hut the FMA and ADL score significantly higher in groups B and C than in the control group (P<0.05), and the differences were more obvious in group C. Groups B and C had greater effective rate than group A (P<0.05), and the rate was the highest in group C (P<0.05). Conclusion Electro-acupuncture combined with early rehabilitation promotes the recovery of motor function in ACI patients probably by regulating the expressions of the adhesion molecules CD11b and CD18 on the PMN and monocytes and the serum levels of TNF-α.     

纤变灵对口腔粘膜下纤维化及血液流变学的影响
