腹腔镜与开放性肾囊肿去顶术的临床对照分析

目的评价腹腔镜与开放性肾囊肿去顶术的临床疗效。方法回顾性分析采用经后腹腔镜和经腹腔镜行肾囊肿去顶术21例，其中经腹腔5例，经后腹腔16例，与开放性手术16例比较。结果手术时间，术中平均出血量，术后下床活动时间，术后住院天数，术后并发症腹腔镜组均优于开放手术组，住院费用腹腔镜组略高于开放性手术组。结论腹腔镜肾囊肿去顶术治疗单纯性肾囊肿安全、有效。应成为治疗单纯性肾囊肿的首选方法。

改良Hardinge入路在非骨水泥全髋置换术中的应用

目的：对改良Hardinge入路行全髋置换进行评价。方法：对经改良Hardinge入路行非骨水泥全髋置换（THR－CL）术并获术后6个月以上随访的32例病人进行总结。结果：优良28例（88％），很好4例（12％），其中轻度跛行6例（19％），下肢不等长＞2cm1例（3％），改良Trendelenburg试验阳性3例（10％）。结论：此入路创伤小，暴露好，利于假体定位，易于控制下肢长度，术后外展肌功能恢复快。     

合理使用高张葡萄糖

临床护理工作中发现，高张葡萄糖的使用，在某些情况下存在一定的危险性，使用不当则加重病情的发展，甚至危及病人的生命。因此要掌握好高张葡萄糖对某些疾病所产生的不良影响，做到预防在先，合理使用。

羊水细胞培养宫内诊断的应用(附120例分析)

报告120例羊膜腔穿刺羊水细胞培养结果:在成功的99例中,发现二例染色体异常,核型为47,xy,+18和46,xx/47,xx,+F,在21例失败中出现一例眼球畸形。培养成功率为82.5%;染色体异常检出率为2.02%。无一例因羊膜腔穿刺而导致流产,但出现一例轻度羊水栓塞合并症。并对羊水细胞培养在产前宫内诊断中应用价值及术后并发症进行了讨论。     

Rib-vertebral angle asymmetry in idiopathic, neuromuscular and experimentally induced scoliosis

The concave and convex rib-vertebral angle (RVA) at levels T2–T12 was measured on AP radiographs of 19 patients with right convex idiopathic thoracic scoliosis and 10 patients with major thoracic right convex neuromuscular scoliosis. The difference between the angles on the concave and the convex sides, the RVAD, was calculated. The RVAs were also measured on radiographs from three animal groups in which spinal curves had been induced experimentally in a variety of ways. Group 1 comprised 16 rabbits that had been subjected to selective electrostimulation of the latissimus dorsi, the erector spinae and the intercostal muscles. Group 2 comprised four dead rabbits whose spines had been subjected to manual bending. Group 3 comprised eight rabbits that had undergone mechanical elongation of one rib. In both the idiopathic and the neuromuscular group, the convex RVA was smaller than the concave RVA between levels T2 and T8, with a maximal difference between T4 to T5. From T9 to T12 the concave RVA was smaller than the convex. The RVA in relation to the scoliotic segment, i.e. the apex level of the curve and the two neighbouring vertebrae above and below this level, showed similar results. With increasing Cobb angle the RVADs increased linearly with the greatest difference at the second vertebra above the apex. In the three experimental groups the pattern of the RVADs between T6 to T12 was basically similar to the findings of the clinical study. From the results of these clinical and experimental studies, it is concluded that the typical pattern of the RVAs on the concave and convex sides seems to be independent of the underlying cause of the spinal curvature. It is likely that the RVADs result from a passive mechanical adaptation of the ribs to the lateral curvature of the spine.     

Experimental studies on preventive effects of API0134 on vessel reocclusion after thrombolysis

Summary 24 model rabbits with femoral arterial thrombosis were divided into two grocps: the treatment group consisting of 12 rabbits which received API₀₁₃₄. and the control group composed of another 12 rabbits. 2 hours after recanalization by urokinase thrombolysis, reocilusion occurred only in 1/12 vessel (8%) with incomplete occlusion in the treated group, but in 8/12 (67%) with complete occlusion in the control group as assessed by angiograsphy. Pathological examination of specimen taken 24 hours after thrombolysis showed that 6/12 (50%) of the treated group gave the evidence of thrombus occlusion, and milder intimai injury and less adhered blood cells than in the control group, 83% of which had thrombus occlusion. In comparision with the control group, the function of platelet in the treated group demonstrated lower platelet aggregation rate (PAgR) and plasma thromboxane A₂ (TXA₂) level, higher prostacyclin (PGI₂) and plasminogen activator (PA) activity as well as lower plasminogen activator inhibitor (PAI) activity. From the above it may be concluded that the preventive effect of API₀₁₃₄ on reocclusion might be due to inhibition of platelets aggregation and promotion of fibrinolysis.     

健侧颈7移位治疗臂丛神经根性撕脱伤最佳时间选择的实验研究

健侧颈７移位治疗臂丛神经根性撕脱伤手术分第一阶段（健侧颈７移位到移植神经），第二阶段（移植神经另一端移植修复患侧神经），二次手术间隔多少时间才能获得最好的神经再生？选用ＳＤ大鼠及健侧颈７移位的实验模型，按二次手术间隔时间的不同（０、１、２、３、４、８、１６周）分成７组，在第二次术后１２周，进行电生理测定肌张力恢复率及组织切片的形态学观察，结果证实二次手术最佳间隔时间为４～８周．此结果可提供临床参考．
