改良超滤对婴幼儿心脏手术输血的影响

目的　观察改良超滤技术在婴幼儿体外循环心血管手术中对输血及术后出血的影响。方法　 6 0例接受体外循环下心血管手术的先天性心脏病患儿 ,均分为对照组 (不接受任何超滤 )、常规超滤组 (CUF组 )和改良超滤组 (MUF组 )。观察术中库血用量、血浆用量、血球压积的变化及术后2 4h出血量 ,并用SSPS/PC进行统计学处理。结果　MUF组库血用量、血浆用量、术后 2 4h出血量显著低于对照组和CUF组 (P <0 0 1) ,且滤出水量明显多于CUF组 (P <0 0 1)。结论　在婴幼儿心血管手术中 ,改良超滤可有效排出体内水分 ,提高血球压积 ,明显减少输血及术后出血 ,是节约用血的重要手段之一。     

影响脐血IgE值因素的研究

目的　本研究对影响脐血IgE值的可疑因素进行分析 ,探讨影响儿童食物过敏的可疑因素。方法　选取孕期妇女 10 5名及其所生婴儿 ,采用标准问卷调查获取资料 ,对影响脐血IgE的因素进行分析。 结果　母亲的过敏性疾病史、父亲过敏性疾病史中的皮炎表现型、孕期妇女过敏性疾病发作史、有过敏史妇女孕后期摄入过量的牛奶和鸡蛋均与脐血IgE值的上升有关 ,且上述 5个因素对脐血IgE水平的影响依次降低。 结论　母亲的过敏性疾病史和父亲过敏性疾病史中的皮炎表现型是导致新生儿脐血IgE值升高的主要危险因素 ;同时 ,妊娠期加强对有过敏史妇女的保护 ,防止过敏性疾病的复发 ,在孕后期控制有过敏史妇女牛奶、鸡蛋等大分子食物致敏原的摄入 ,有助于降低脐血IgE值。     

经皮椎体成形术治疗脊柱疾病

目的评价经皮椎体成形术治疗脊柱疾病的临床应用价值.方法 56例多发骨髓瘤、溶骨性脊柱转移瘤、骨质疏松性椎体压缩性骨折患者应用经皮椎体成形术后,分24 h、3个月两阶段评估患者疼痛、术后X线片检查结果、椎体高度等指标.结果术后止痛效果良好,尤以骨质疏松性椎体压缩性骨折患者的止痛效果最好.无严重并发症. 结论经皮椎体成形术对骨质疏松性椎体压缩性骨折等脊柱疾病的止痛、稳固椎体等效果明显,可以谨慎开展.     

Antegrade interlocking nailing of humeral shaft fractures

The results of 39 humeral shaft fractures (37 patients) treated with antegrade locked nailing using a Russell–Taylor nail were reviewed. There were 30 acute fractures, 6 fractures malaligned in a hanging cast or brace, and 3 pathological fractures. Patient age ranged from 26 to 80 years (average, 59.7 years) and average follow-up was 25.7 months (range, 6–48 months). Fracture union was achieved in 92.3% of our cases, while shoulder function was excellent or good in 87.2% of cases. Antegrade locked nailing offers a dependable solution for the treatment of humeral shaft fractures, especially in polytrauma patients and cases of segmental or pathological fractures. Far less satisfactory results were obtained in comminuted fractures of the proximal third in the humerus, especially in osteoporotic patients, and we therefore advocate caution with the use of intramedullary nailing in this type of fracture. Certain technical aspects such as avoiding nailing the fracture in distraction, properly countersinking the tip of the nail, and achieving adequate fixation stability have been found to be of paramount importance to reduce the incidence of delayed union/non-union rate and to obtain better functional results from the shoulder joint.     

脑梗死后抑郁与负性生活事件相关性研究

目的　探讨脑梗死后抑郁与负性生活事件的关系。方法　将脑梗死患者按是否受负性生活事件影响分为 A(n=75 )、B(n=73)两组。采用抑郁自评量表 (SDS)及 Hamilton抑郁量表筛查 ,对两组进行比较分析 ,并观察其治疗效果。结果　A、B两组脑梗死后抑郁的发生率分别为 5 6 %、38.4 % ,两者比较差异显著 (P<0 .0 5 ) ;百忧解可显著改善或治愈脑梗死后抑郁 ,总有效率 6 1.7%。结论　脑梗死后抑郁发生与负性生活事件相关。百忧解治疗有效     

Biliopancreatic diversion with duodenal switch vs. gastric bypass for severe obesity

Conclusion In the year 2003 there is no “one best bariatric operation” for every severely obese patient. The choice of operation must be tailored to each individual patient’s needs and wishes. For the superobese patient, the patient diagnosed with intestinal metaplasia of the stomach, and for those patients who do not wish to undergo the severe dietary restrictions imposed by the RNY-GB, the BPD-DS is a valuable surgical option.     

颈前部皮神经构筑研究

目的　为研究皮肤疾病和损伤提供皮神经构筑资料。方法　用S 10 0蛋白免疫组化染色法研究正常成人颈前部胸锁乳突肌前、后缘皮肤各层内皮神经的数量、分布及构筑特点。结果　 ( 1)皮肤乳头层内皮神经的小分支多分布在皮突下和乳头内血管丛附近。 ( 2 )真皮网状层内神经多位于小血管附近和汗腺、皮脂腺以及毛囊周围 ,神经分支呈串珠状或波纹形。 ( 3 )皮下组织内神经干和神经网同时存在。结论　皮肤内感觉神经树的分布及构筑特点与血管树相似。
