p73在骨巨细胞瘤中表达的意义

目的：研究p73蛋白在骨巨细胞瘤中的表达,探讨其在骨巨细胞瘤发生、发展中的可能作用。方法：应用免疫组化S－P法检测40例骨巨细胞瘤石蜡标本中p73蛋白的表达情况。结果：p73在骨巨细胞瘤中表达阳性率为30.0％,对照组骨软骨瘤表达阳性率为20.0％,两组相比无显著差异（P＞0.05）。p73在骨巨细胞瘤Ⅰ～Ⅱ级组表达阳性率为17.9％,Ⅲ级组为58.3％,二者相比差异显著（P＜0.05）。结论：p73在Ⅲ级骨巨细胞瘤中表达明显增高,提示其在骨巨细胞瘤发生、发展中可能发挥重要作用,并可作为骨巨细胞瘤Jaffe分级的辅助指标之一。

晚期肺癌患者化疗相关性味觉改变与生活质量及应对方式的相关性

目的 了解肺癌患者化疗相关性味觉改变的发生现状,并分析其与生活质量、应对方式的相关性,为制订针对性的措施减轻患者味觉改变提供参考.方法 对144例晚期肺癌化疗患者采用中文版化疗相关性味觉改变量表、癌症患者生命质量量表和医学应对方式量表进行问卷调查.结果 晚期肺癌化疗患者味觉改变发生率为54.9％;患者化疗相关性味觉改变总分为7.60±2.57,化疗相关性味觉改变与生活质量量表功能维度、总体健康状况呈显著负相关,与部分症状维度呈正相关(P＜0.05,P＜0.01);医学应对方式量表中面对维度与整体味觉改变总分呈负相关,屈服维度与不适症状和味觉异常维度呈正相关(P＜0.05,P＜0.01).结论 晚期肺癌化疗患者味觉改变发生率较高,处于中重度水平,对患者生活质量造成一定程度影响;患者采取积极应对方式有助于减轻味觉改变.     

How to select the lowest instrumented vertebra in Lenke type 5 adolescent idiopathic scoliosis patients?

BACKGROUND CONTEXTThe lowest instrumented vertebra (LIV) determination in Lenke type 5 Adolescent Idiopathic Scoliosis (AIS) requires a thorough understanding and prediction of the correction force on the LIV from coronal, sagittal, and axial plane. Although many LIV selection criteria have been reported, none of them comprehensively evaluated the multidimensional characteristics of the LIV till now.PURPOSETo develop and evaluate our LIV selection criteria in Lenke type 5 AIS patients using pedicle screw system via posterior approach.STUDY DESIGNA retrospective study.PATIENT SAMPLEAll consecutive patients with Lenke 5 curves who were treated with one-stage selective lumbar fusion using complete pedicle screw system in our center from January 2006 to December 2017, with minimum 2-year follow-up.OUTCOME MEASURESAge, gender and Risser grade, fused levels, operating time, intraoperative blood loss, complications, and Scoliosis Research Society (SRS)-22 questionnaires outcome were recorded. Coronal, sagittal, and axial parameters were measured from plain radiographs.METHODSA total of 138 consecutive patients with Lenke 5 curves treated with selective lumbar fusion were retrospectively analyzed, with minimum 2-year follow-up. Our LIV selection criteria include: (1) the most cephalad vertebrae touched by central sacrum vertical line (CSVL); (2) Nash-Moe rotation being equal or less than grade I on the standing AP radiograph; (3) CSVL cross between the two pedicles of LIV on concave bending film; (4) not at the apex of kyphosis. Radiographic data, operative data, perioperative complications and SRS-22 outcomes were collected and analyzed.RESULTSThe mean follow-up period was 50.9±24.7 months. The thoracolumbar/lumbar curve was corrected from 46.9°±8.9° before surgery to 5.5°±2.6° at the final follow-up. The C7-CSVL was 19.7±6.2 mm before surgery and 5.2±3.4 mm at the final follow-up. The LIV translation was corrected from 22.3 ±5.4 mm before surgery to 4.8 ± 2.6 mm at the final follow-up, with the correction rate of 78.4%. The LIV tilt was corrected from 21.6 ± 4.4° before surgery to 2.6 ± 2.3° at the final follow up, with the correction rate of 87.9%. Our LIV saved 0.3 level than SRS-last barely touching vertebra, 0.6 level than SRS-last substantially touching vertebra, 0.9 level than neutral vertebra, and 1.4 level than stable vertebra.CONCLUSIONThe present study indicates using our LIV criteria, our study achieved the correction rate of thoracolumbar/lumbar curve as 88.9%, with the rate of adding on or coronal imbalance as 8.7% (12/138). The criteria may provide important guidance for preoperative decision-making in Lenke 5 AIS patients, and more multicenter prospective studies with larger samples are needed to further validate the findings of this study.     

骨生丸治疗股骨颈骨折后早期股骨头坏死的实验研究

目的：探讨中药制剂骨生丸治疗股骨颈骨折后早期股骨头坏死的作用机制。方法：按照Kenzora方法,复制大白兔凤骨颈骨折后早期股骨头坏死动物模型,灌药4周后断头取血,取出股容、血沉、还原粘度、聚集指数及纤维蛋白等血液流变性指标。结果：骨生丸能够有效地降低空骨陷窝率,改善血液流变性状态。结论：骨生丸通过逆转股骨颈骨折后早期股骨头坏死的股骨头缺血状态,促进股骨头坏死修复而起治疗作用。
