带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎

目的：阐明带血管蒂岛状筋膜瓣移植治疗晚期类风湿性髋关节炎的疗效。材料和方法：对４２例４８髋晚期类风湿性髋关节炎病人采用以旋股外侧血管降支为蒂的股前外侧筋膜瓣移植行患髋成形术。结果：术后随访４～１０．５年，平均４．５年，髋关节活动范围术前平均１６．５°，术后２２８．６°，按照Ｃｈａｒｎｌｅｙ和吴之康人工髋关节置换术后的疗效评定标准，优良２９髋、很好１３髋、好６髋，尚可、差、很差无。结论：患者年龄在１５～４０岁之间为合适的治疗年龄。与人工髋关节置换术相比，本方法对髋关节正常结构破坏小；一旦手术失败仍可选用其它治疗方法弥补；且并发症少、费用低、远期效果好。

Grose-Kempf 带锁髓内钉在股骨干骨折中的应用

作者从１９８８～１９９５年末用Ｇｒｏｓｅ－ｋｅｍｐｆ钉（简称ＧＫ钉）治疗股骨干骨折４９例（５０个股骨），其中新鲜骨折２９例（３０个股骨），陈旧性骨折１６例，病理骨折４例。外伤性骨折４５例中，随访半年以上４３例，骨折全部愈合，下肢功能及关节活动良好。４例病理骨折，其中３例术后分别存活１６个月、１８个月、２４个月，另１例为成骨不全，术后患肢功能较健侧无差别。ＧＫ钉扩大了髓内钉手术适应证，可用于股骨干的粉碎性骨折、多发性骨折、陈旧性骨折不愈合及病理性骨折。对于合并脑干损伤、血管损伤、骨筋膜室综合征的股骨干骨折，用ＧＫ钉固定，获得了理想的治疗效果。

Chest wall and mediastinum invasion by lung cancer--a CT and MRI evaluation]

CT and MRI manifestations of 52 peripheral lung cancers located close to the pleural surface or mediastinal structures were studied correlating with the surgical and pathologic findings. Rib destruction as shown by CT and T2 weighted MRI showing the encroachment of tumor upon the chest wall were crucial in demonstrating chest wall invasion. An obtuse chest wall intersecting angle and the length of the neighboring borders of the tumor and chest wall were of limited value. Local pleural thickening was observed near the tumor in 54% of cases, over half of them showed obtuse angle between the tumor and the chest wall but without tumor invasion. T2 weighted MRI was more reliable than CT by showing different signal intensities for pleural thickening, inflammation, localized pleural effusion or tumor invasion to chest wall soft tissue.     

体外培养新生大鼠心房壁中的CGRP-IR和NPY-IR神经细胞

对体外培养新生SD大鼠心房壁的神经细胞，按SternbergerPAP法进行了降钙素基因相关肽（CGRP）和神经肽Y（NPY）免疫细胞化学研究。结果显示：CGRP-IR阳性细胞数量较少，实验的5份标本只有2份见到阳性细胞，而NPY-IR阳性细胞在所有实验标本中均可见到。本研究在培养条件下证实心内神经节中有CGRP-IR阳性细胞存在，支持心脏有器官内感觉神经细胞的设想。同时对心内神经细胞的化学性质进行了讨论。     

The popularization and application of cold storage red blood cells or whole blood at −80 °C of the Rh(D) negative patients in surgical operation

Summary The efficiency of cold storage red blood cells (CSRBC) or whole blood at −80 °C used in 27 Rh(D) negative patients during surgical operation was reported. The Rh(D) negative patients received the transfusion of CSRBC or whole blood stored at −80 °C for 180 to 360 days. The changes in the indexes, such as blood TB, DB, K⁺, Na⁺, BUN, Cr, urine protein (URPO), UOB, Hb, HCT, serum total protein, relative to hemolytic reaction and blood volume before and after transfusion were observed. The results showed that after transfusion of CSRBC or whole blood 27 cases were negative for urine protein and UOB, and the levels of BUN and Cr were normal (P>0.05). Blood TB, DB, Hb, and HCT were increased, while pH, blood K⁺ and blood Na⁺ was normal with the difference being not significant before and after operation (P>0.05). Plasma protein was decreased, but there was no significant difference before and after operation (P>0.05). It was suggested that CSRBC or whole blood at −80 °C could be safely infused to the Rh(D) negative patients without side effects during the surgical operation.

视觉近点测定修布和验布作业视疲劳的初步探讨

应用视觉近点测定评价纺织厂不同作业工人的视疲劳。检查了32名修布工人和38名验布工人。同一工厂的33名保育员作对照组。结果表明:视觉近点的测定指标比调查受试者主诉的眼视觉症状更为敏感。修布和验布组在工作后,作业者的视觉近点比上班前明显变远,但时照蛆工作前后无明显变化。三组视觉近点比较,发现修布和验布组视觉近点的变化。提示由修布和验布作业引起的视觉疲劳,可以通过测定视觉近点来进行评价。     

皮肤交界性平滑肌瘤的复发与恶性转化

目的探讨皮肤交界性平滑肌瘤的复发与恶性转化。方法复习2例皮肤交界性平滑肌瘤及其复发恶性转化的临床病理特征、免疫组化表型及相关文献。结果2例病变位于下肢和额部，肉瘤组织平滑肌标记阳性。结论少数病理诊断为皮肤平滑肌瘤的病例，虽然浅表且组织形态良性，但其生物学恶性潜能尚不能确定，部分病例复发后可转变为典型的平滑肌肉瘤。
