目的：研究比较纸夹板内收位固定与石膏外展位固定治疗Bennett骨折的疗效差异。方法：选择2005年10月至2007年4月门诊就诊的70例Bennett骨折患者，按区组随机的方法分为试验组35例（纸夹板内收位固定）和对照组35例（石膏外展位固定）进行治疗。骨折达到临床愈合拆除固定后，对患者进行为期6个月的随访观察。分别于骨折后6、8、12、16、20及24周按改良的Gabriele评分系统对其患手功能进行量化评分比较。结果：两组的优良率在8、12、16及20周时比较试验组优于对照组，差异有统计学意义（P〈0．05）；6周和24周时比较差异无统计学意义（P〉0．05）。两组在功能评分方面，8、12、16、20及24周时比较试验组高于对照组，差异有统计学意义（P〈0．05）；6周时积分差异无统计学意义（P〉0．05）。结论：在Bennett骨折的治疗中，纸夹板内收位固定与石膏外展位固定相比能明显加快患手功能的恢复，而且固定轻便、舒适，患者易于接受，可以作为一种有效的固定方法在临床推广。     

血清P-选择素水平与冠脉病变严重度关系的研究

目的：探讨检测血清P-选择素水平与冠脉病变严重度的关系。方法：70冽冠D病患者，按临床诊断分为2组：急性冠脉综合症组32冽和稳定型冠心病组38例，对照组患者30例。ELISA检测各组患者血清中P-选择素水平．并比较各组间的差异；冠脉造影术对冠脉病变进行Gensini评分，并了解其与血清中P-选择素的相关性。结果：冠心病患者血清中的P-选择素水平显著高于正常对照组；在冠D病组内，急性冠脉综合症组的P-选择素水平显著高于稳定型冠心病患者，但两组冠脉病变Gemini评分无显著差别；而且冠脉病变Gemini评分与血清中P-选择素水平呈明显的相关性。结论：P-选择素可能参与了冠状动脉粥样硬化的发生和发展过程，血清P-选择素水平可能是冠脉病变严重度的一个预测指标。

Alpha-smooth muscle actin in pathological human disc nucleus pulposus cells in vivo and in vitro

That a contractile actin isoform has been found in cells of other cartilage tissues in healing and disease states prompted this investigation of the presence of alpha-smooth muscle actin (alpha-SMA) in pathological human intervertebral disc tissue. The presence of this isoform has been reported in human intervertebral disc specimens obtained at autopsy from subjects for whom there were no reported symptoms. An objective of this study was to evaluate the cell density and percentage of alpha-SMA-containing cells in pathological nucleus pulposus tissue obtained from lumbar disc surgery from 17 patients. Additionally, explants of nucleus pulposus material were cultured to determine how alpha-SMA expression changed with time in vitro. Seventy-six 5-mm diameter explants (approximately 2 mm thick) pooled from six lumbar surgeries were cultured for 1, 2, 4, or 6 weeks. Microtomed sections of paraffin-embedded specimens were stained with hematoxylin and eosin or a monoclonal antibody to alpha-SMA. Histologically, cells were categorized as to alpha-SMA phenotype (positive or negative), and the areal cell density was determined. The evaluation of the cultured nucleus pulposus explants also included documentation of the percentage of cells that were round or elongated and the percentage of the cells that were part of a group (group: >/= 2 cells). Every nucleus pulposus section exhibited the presence of alpha-SMA-containing cells, which accounted for approximately 24 percent of the cells in vivo. In vivo, the cell density was significantly higher in older individuals (p = 0.02). The average time for cell outgrowth from the explants was 8.6 days. Approximately 10-15 percent of the cells in the explants stained positive for alpha-SMA. The time in culture had no significant effect on any of the outcome measures except the percentage of alpha-SMA-containing cells that were round (p = 0.008), with values decreasing through 4 weeks and then slightly rising at 6 weeks. The role of alpha-SMA in intervertebral disc pathology warrants further investigation.
