肝郁痰凝型乳腺癌的钼靶X线表现及病理分析

目的：研究肝郁痰凝型乳腺癌的钼靶X线影像特点，探讨其病理基础。方法：观察41例中医证型为肝郁痰凝型、术后病理检查结果为乳腺癌患者的钼靶X线影像表现，对其病理学基础进行分析。结果：41例肝郁痰凝型乳腺癌中，乳腺类型以致密型及混合型居多（占78％）。异常血管征及透环征出现频率较高（占80％以上）。腋淋巴结转移出现频率偏低（占12％）。结论：（1）肝郁痰凝型乳腺癌患者，乳腺密度多偏高，可能与较多发生在绝经期前有关。（2）肿瘤周围透亮环征象及异常血管征象出现频率较高，表明此型患者肿块周围脂肪代谢异常较为普遍及血管生长刺激因子分泌较多。（3）腋窝淋巴结转移者所占比例较小，可能是由于此类患者多属于癌变早、中期，相对气血不足或脾肾虚弱等正虚表现不明显。     

中心静脉导管胸腔留置治疗胸腔积液

目的评价中心静脉导管留置治疗胸腔积液的疗效。方法257例胸腔积液患者分为两组，治疗组207例，应用胸腔留置中心静脉导管治疗；对照组50例，常规胸穿抽液治疗，观察并比较不同治疗方法的疗效、并发症等指标。结果两组对比多项指标差异有显著性（P〈0．05）。结论采用中心静脉导管治疗胸腔积液可减少胸穿次数、降低反应，提高治愈率。     

Selective dorsal rhizotomy: efficacy and safety in an investigator-masked randomized clinical trial

The objective of this single-center investigator-masked randomized clinical trial was to investigate the efficacy and safety of selective dorsal rhizotomy (SDR) in children with spastic diplegia. Forty-three children with spastic diplegia were randomly assigned on an intention-to-treat basis to receive SDR plus physical therapy (PT), or PT alone. Thirty-eight children completed follow-up through 24 months. Twenty-one children received SDR (SDR+PT group) and 17 received PT (PT Only group). SDR was guided with electrophysiological monitoring and performed by one experienced neurosurgeon. All subjects received equivalent PT. Spasticity was quantified with an electromechanical torque measurement device (spasticity measurement system [SMS]). The Gross Motor Function Measure (GMFM) was used to document changes in functional mobility. Primary outcome measures were collected at baseline, 6, 12, and 24 months by evaluators masked to treatment.
At 24 months, the SDR+PT group exceeded the PT Only group in mean reduction of spasticity by SMS measurement (-8.2 versus +5.1 newton meters/radian, P=0.02). The SDR+PT group and the PT Only group demonstrated similar improvements in independent mobility on the GMFM (7.0 versus 7.2 total percent score, P=0.94). Outcomes on secondary variables were consistent with primary outcomes. There were no serious adverse events. We conclude that SDR is safe and reduces spasticity-in children with spastic diplegia. SDR plus PT and equivalent PT without SDR result in equal improvements in independent mobility at 24 months. SDR may not be an efficacious treatment for children with mild spastic diplegia.     

Excision of a recurrent mediastinal cyst through mid sternotomy with high thoracic epidural anesthesia as the sole anesthetic—A case report

Conclusion Our case report highlights the possibility of tackling mediastinal, pericardial and pleural problems with regional anesthesia alone even if the surgery requires opening of the pleura.
