南海某岛礁作业人员睡眠状况与身心健康状况关系的研究

目的 研究南海某岛礁作业人员睡眠状况与身心健康状况的关系。方法 由经过统一培训的医务人员连续91d每日逐人逐项当面调查、记录。其中的“指数”指标，采用视觉模糊评分法。结果 随着在礁时阃的延长，作业人员睡眠状况明显变差，其主要影响因素依次为值勤（28．73％）、情绪（20．09％）、多梦（10．16％）、噪音（8．86％）和气候（7．73％）等。睡眠状况与身心健康状况明显相关，相关系数7=0．937～0．980，P＜0．01；睡眠指数对身心健康状况各指标均有明显影响（P＜0．01），睡眠时间主要影响体能指数、健康指数、工作质量指数、工作积极性指数、注意力指数及情绪指数等（P＜0．05～0．01），对食欲指数、记忆力指数影响则不明显。结论 在岛礁期间，影响作业人员睡眠的主要因素是值勤和情绪，睡眠状况明显影响身心健康状况。     

The patella and tibial condyle position after combined and after closing wedge high tibial osteotomy

High tibial osteotomy changes the patella and tibial condyle position, which makes the subsequent total knee replacement technically demanding. From 1 January 1993 to 31 December 2000, combined osteotomy [After the first osteotomy made 2 cm distally to the joint line, a bone wedge is removed based laterally. Its tip ends at the center of the tibial condyle (half bone wedge). The distal part of the tibia is placed into the valgus position and the half bone wedge is placed into the gap opened medially.] was performed on 103 knees and closing wedge osteotomy was performed on 47 consecutive knees. Eighty combined (group A) and 41 closing wedge (group B) osteotomy were studied. All knees were assessed radiologically before surgery, in the 10th postoperative week, in the 12th postoperative month and at the time of the final follow-up (in group A—66.15 months, in group B—66.61 months). We examined the change of the femorotibial angle, of the patellar height according to the method of Insall and Salvati, of the tibial slope angle according to the method of Bonnin, of the tibial condylar offset according to the method of Yoshida and of the distance between the lateral tibial plateau and the top of the fibular head. In group A and B, the recurrence of the varus deformity was not noted and valgus alignment did not increase in any case. In group-A, the Insall–Salvati ratio remained unchanged in 65% of knees. The tibial slope angle decreased in both groups. There was correlation between the change of the tibial condylar offset and the angle of the correction in both groups. There was correlation between the change of the distance between the lateral tibial plateau and the top of the fibular head. After combined osteotomy, the transposition of the tibial condyle and the decrease of the distance between the lateral tibial plateau and the top of the fibular head was less than after closing wedge osteotomy, although the average angle of correction was more after combined osteotomy (11.835°), than after closing wedge osteotomy (9.465°). Theoretically, the recurrence of the varus deformity, the increase of the valgus alignment and (in majority of cases) the shortening of the patellar tendon do not compromise the likelihood of successful conversion to the subsequent total knee replacement, either after combined or after closing wedge osteotomy. The combined osteotomy does not lead to considerable transposition of the tibial condyle and to considerable lateral tibial bone loss; therefore, theoretically, the combined osteotomy does not impair the subsequent total knee replacement.     

永磁速愈贴对妇产科手术切口愈合的观察

目的探讨永磁速愈贴对切13的消肿止痛，促进伤口愈合和防止疤痕粘连与普通敷料进行对比观察。方法将住院行妇产科手术100例患者与同期住院的手术患者进行对比观察。结果永磁速愈贴切13愈合佳者84．0％，良好者13．0％，愈合差为3．0％，而普通敷料为28．0％、60．0％和12．0％，p〈0．01（x^2=63．660）。结论永磁速愈贴切口具有透气、保湿、促进伤口愈合、消肿、止痒，防止疤痕形成等作用。而普通敷料透气性差，保湿性差，术后切口有红肿、缝线反应、切口愈合时间长及切口局部愈合后有痛痒感。     

强心力胶囊治疗充血性心力衰竭彩色多谱勒超声心动图检测指标分析

目的观察强心力胶囊对慢性充血性心力衰竭患者心脏左心室功能的影响。方法运用彩色多谱勒超声心动图,测量慢性充血性心力衰竭患者左心室舒张末及收缩末内径(D s和Dd)、左心室每搏量(SV)、心输出量(CO)、左心室短轴缩短率(FS)和射血分数(EF)等指标。结果强心力胶囊治疗后患者收缩末期内径(D s)、流量指标(SV和CO)和泵功能指标(EF和FS)均有明显改善,但治疗后收缩末期内径D(d)和E A/比值无明显变化。结论强心力胶囊具有治疗充血性心力衰竭的作用。
