单纯性小肠旋转不良（附90例分析）

在胃肠道钡餐造影检查时，偶可发现有些病例的近段小肠位于右侧腹部。自1986年6月-1994年12月共发现该种病例90例。现将其临床资料和X线表现进行报道，并结合文献探讨其发生机理及临床意义。临床分析     

断流术后门静脉系统血栓形成八例

本组8例中,男3例,女5例,年龄40～68岁。发生在断流术后住院期间5例,均经螺旋CT增强扫描证实。因发现及时,经溶栓、抗凝、祛聚等治疗痊愈。另3例分别发生在手术后4个月、1年、5年,其中例1发病20d后由外院转入,入院时已经出现弥漫性腹膜炎、中毒性休克,螺旋CT扫描提示门静脉及肠系膜上静脉血栓形成,腹腔大量积液,经溶栓、祛聚等治疗,病情未见好转,家属放弃治疗自动出院。例2突发腹痛3d入院,有明显腹膜炎体征,腹穿为血性腹水。螺旋CT检查见肠系膜明显水肿增厚,腹腔积液,门静脉及肠系膜上静脉充盈缺损。急症手术切除坏死空肠2m,经残端肠系膜…     

Baumann角测定在儿童肱骨髁上骨折的应用

肱骨髁上骨折系指肱骨远端内外骨髁上方2～3cm骨折。是儿童骨折中比较常见的疾病。而肘内翻畸形也称“枪托（Gunstock）畸形”．是其最常发生的远期并发症．献报道其平均发生率为30％．高达57％。自2001年5月至2005年5月共收治儿童肱骨髁上骨折96例．应用Baumann角（简称B角）与提携角（简称C角）的负相关性进行临床指导．取得一定的临床疗效。现总结如下。     

Evaluation of Mechanical Properties of ZY-1 Maxillofacial Prosthetic Materials

Objective Maxillofacial prosthetic materials are used to replace facial parts lost through disease or trauma. Silicone rubbers are the materials of choice. The silicone elastomer A-2186 is a widely used maxillofacial prosthetic material. It is a pourable two-component silicone rubber cured by a platinum catalyst. Used as a prosthetic material, A-2186 has short working time and good mechanical properties. The purpose of this study is to evaluate the physical properties of new prosthetic materials based on addition-type silicone elastomer （ZY-1）, and compared the mechanical properties with those of A-2186, Methods Hardness, tensile strength, ultimate elongation, tear strength and adhesive bonding strength of ZY-1 and A-2186 were compared. Statistical analyses were done using a two-way analysis of variance （ANOVA）. Results The hardness and ultimate elongation of ZY-1 is similar to A-2186. However, tensile strength, tear strength of ZY-1 were higher than those of A-2186. Conclusion ZY-1 addition-type silicone elastomer processed good mechanical properties for use as a maxillofacial prosthetic material.     

浅谈胰腺炎疼痛的护理体会

急性胰腺炎分为单纯水肿型和出血坏死型两类，单纯水肿型又以胆源性胰腺炎为多见。急性胰腺炎以上腹部疼痛最常见，出现最早，位于腹部正中偏左，突然发生，急骤发展，呈现刀割样疼痛，疼痛常放射到肩部、腰部、肋部，这是由于胰腺炎水肿刺激腹腔神经丛所致，腹痛加剧的同时可出现休克，甚至危及生命。腹痛同时出现腹胀，为腹膜炎胃肠麻痹所致，常伴有排便排气中止。[第一段]
