全大肠切除直肠肌鞘内回肠造袋肛门吻合术治疗家族性腺瘤性息肉病

家族性腺癌性息肉病（ＦＡＰ）为一种常染色体显性遗传病，如不手术治疗终将发生癌变。现已公认本病的最佳术式为全大肠切除，直肠粘膜剥除，回肠造袋肛门吻合术。作者近９年内施行此手术１１例。患者年龄为１９～６５岁。５例在３０岁以内。平均随访１～９年，效果满意。除２例切口感染外无其它并发症。每日大便４～６次，能恢复工作。手术时５例已有恶变，其中１例有单个肝转移灶同时行局部切除。手术要点为：肌鞘宜短，充分止血并放置引流，无张力吻合，保护性回肠造口。作者认为除直肠内仅少数息肉，患者能坚持随访者外，均宜采用本术式。     

中医对干燥综合征治法和用药初探

干燥综合是一种全身性自身免疫病,目前西医对本病无疗法。因此探讨中医对本病的治法和用药,提高临床有效率是十分必要的。本文在中医辯证理论的指导下,提出了:益气养阴、养阴清热、琉风清热、养血活血、清热化湿、痹通络等六种治疗方法和用药初探,以供临床参考应用。     

间断缺血心停搏在冠脉搭桥术中的应用

１９９２～１９９３年间为１８０例冠脉病变的病人施行冠脉搭桥术，全部病人均采用核甙抑制剂利多氟嗪预处理和低温（２８℃）间断缺血心停搏进行术中心肌保护。平均每例病人作冠状动脉端吻合３～４个，每个吻合口用９分钟，主动脉阻断累加时间约２５分钟，体外循环时间９０分钟，术后医院死亡率１．６％（３／１８０），无术后心梗发生。作者认为，冠脉搭桥术的术中心肌保护可采用核甙抑制剂和间断缺血心停搏方法，而不用心肌停搏液。     

胸腰椎稳定性重建方法的改进

为了改进胸腰椎脱位的治疗方法，更好地重建脊柱稳定性，设计了一种新的脊柱固定器械，由滚花钉及连接板构成，并通过椎弓根进行的一种脊柱后路短节段固定方法，脊柱固定范围限制在两个椎体间。１９８９年～１９９５年，临床应用这种新器械矫正胸腰椎脱位１２例，经１～４年随访，畸形矫正满意，固定牢固。结果表明：该器械具有手术方法简单、固定牢固和手术创伤小等优点。认为，该项技术适用于胸腰椎稳定性的重建。     

Root avulsion of brachial plexus in infants and children.

Twenty-one patients, under 6 years of age, with root avulsion of the brachial plexus were treated from 1975 to 1987. Among them, 9 had root avulsion of the upper trunk, 2 root avulsion of the lower trunk with middle trunk broken, and 10 root avulsion of the whole brachial plexus. Follow-up of 16 patients showed excellent results in 2 patients, good in 11, fair in 1 and poor in 2. It is suggested that good results can be obtained if multi-paired nerve transfer is adopted in treatment. We conclude that owing to anatomical and physiological characteristics of the respiratory system in children, it is harmful to perform phrenic nerve transfer concomitantly with intercostal nerve transfer. Advisably, two-stage operation is required, otherwise dyspnea and pneumonia are liable to occur. In addition, the time of the operation could be extended to 4-5 years after injury in children, but best results are obtained if the operation is performed within 1 year.

     

近节指骨段屈肌腱鞘不同范围损伤对肌腱功能的影响

目的 探索手指屈肌腱在近节指骨段不同范围损伤时对屈指肌腱功能的影响。方法 采用12只成人尸体手指。实验分为:第一阶段屈指肌腱完整,以后四个阶段依次沿近节指骨掌侧小线闭开小央1/4、1/2、3/4及全长。在掌指关节被动屈80°和掌指关节屈80°同时近侧指关节屈100°时,测量指浅屈肌腱(FDS)和指深屈肌腱(FDP)的滑动距离。根据肌腱力臂和滑动距离的关系,得出屈指肌腱在掌指关节处和近侧指间关节及肌腱在近节指骨段的弓弦畸形程度。结果 腱鞘中央1/4切开时,指屈肌腱的滑动距离、力臂均无显著变化;1/2切开后,单纯屈曲掌指关节时的FDS腱和掌指、近节指间关节屈曲时的FDS、HDP腱的滑动距离和力臂较腱鞘完整时显苫增大(P<0.05);切开3/4长度后,FDS、FDP腱滑动距离均有统计学意义变化,FDS、FDP腱力臂平均增加8～9％;全切开腱鞘,FDS、FDP腱滑动距离变化正统计学上有高度显著性(P<0.01),两腱力臂分别增加16％和15％。随腱鞘切开范围增大,FDS、FDP在近节指骨段的弓弦畸形程度也越来越大。结论 从肌腱的生物力学变化可见,近节指骨段腱鞘的小范围损伤如中间1/4以内损伤时,对肌腱功能影响小,可以不予修复;若损伤超过1/2长度,尤其对腱鞘全长损伤,应予以修复以恢复肌腱功能。

Hereditary characteristics of enzyme deficiency and dermatoglyphics in congenital color blindness

The hereditary characteristics of enzyme deficiency and dermatoglyphics in congenital color blindness (CCB) were studied. We propose that there is a linkage between the two loci on the X-chromosome determining CCB and glucose-6-phosphate dehydrogenase (G6PD), based on our study of a high incidence of G6PD deficiency in 156 male cases with CCB. The CCB gene is closely linked with that of G6PD deficiency from our pedigree investigations. The rise in the frequency of eight or more whorls, the low value of atd angle and the presenting rate of real palmar patterns of the thenar, hypothenar and I, areas presented the hereditary traits of congenital color blindness.
