Background:Defecation of patients with rectal carcinoma after operation cannot be controlled freely,which brings patients many mental burdens.Cocolyster operation can improve obviously the symptom.     

急性脑出血220例心电图分析

目的探讨脑出血急性期心电图异常的表现及特征。方法回顾分析220例住院各类急性脑出血患者的心电图资料,并分析其特点及与脑出血的关系。结果脑出血后继发心电图改变主要表现为ST-T改变和(或)心律失常。结论脑出血心电图异常与疾病的严重程度密切相关。心电图的异常可随脑血管病情的减轻而好转或消失,并对脑血管病情的预后有积极的意义。对高龄、高血压病等具缺血性心脏病的危险因素的人群,应加强监护。     

Diagnosis and management of obstetric acute disseminated intravascular coagulation]

Twenty-seven in-patients with obstetric DIC in our hospital from Jan. 1971 to Dec. 1990 were analysed retrospectively. The incidence was 0.12% in the first decade and 0.02%, in the second, showing a difference of significance between them. The most common predisposing factors included amniotic fluid embolism, abruptio placenta and hemorrhagic shock. Bleeding from multi-organs in various extent and coagulation disorders occurred in all those 27 cases. [Besides anti-shock treatment, heparin was employed together with fibrinogen in 4 postpartum and 1 antepartum DIC patients, fibrinogen alone in 8 cases, and hysterectomy in 11 cases. 17 patients were saved and 9 died. It is important that early diagnosis and much attention paid to clinical characteristics together with serial laboratory tests. Key management should include prompt treatment and eradication of predisposing factors. Quick decision spite of to terminate the pregnancy and even hysterectomy should be done in some risks.     

透刺法配合按摩治疗周围性面神经麻痹病人的临床观察及护理

周围性面神经麻痹称之面瘫，以口眼向一侧歪斜为主症，俗称口眼歪斜。本病如果治疗不及时或治疗不当，则久治不愈，给病人造成极大痛苦。若单用针刺治疗疗程较长，疗效不显著。我科在运用针灸按摩治疗本病的同时，对病人实施了针对性的全面的护理措施。现介绍如下。     

微量元素硒和维生素E联合应用对家兔实验性脂质过氧化的保护作用

目的:探讨Se和VitE联合应用对胆固醇诱发家兔脂质过氧化的保护作用。方法:制作动物模型,设对照组,分组进行脂代谢观察。结果:Se、VitE联合应用降脂、抗脂质过氧化作用,优于单独应用。结论:Se、VitE联合应用有协同抗脂质过氧化作用,亦可升高HDL水平。     

MRI顺磁性造影剂增强及护理

目的 :进一步探讨 MRI增强前后的准备与护理方法。材料与方法 :共增强 833例 ,男 5 85例 ,女 2 4 8例。使用顺磁性造影剂 Gd- DTPA,按 0 .2 m L/kg体重给药。其中双倍量增强 110例 ,增强前认真履行告知义务和签署同意书。发生造影剂外漏者给予鲜马铃薯片外敷。结果 :增强效果达良好以上共 82 5例 ,占 99% ,未发生严重负反应。 3例造影剂外漏 ,鲜马铃薯片外敷后 3h痊愈。结论 :增强前充分细致的准备是保证增强效果的重要因素。认真履行告知义务和签置同意书 ,不仅尊重了病人的权利 ,也是依法行医 ,保证医疗安全的需要     

环氧合酶-2和血管内皮生长因子共表达与肝细胞癌血管形成的关系

目的　探讨环氧合酶 (COX) 2与肝细胞癌血管形成的关系。方法　利用免疫组织化学、Westernblot方法检测 48例肝癌组织中COX 2和血管内皮生长因子 (VEGF)蛋白及逆转录 聚合酶链反应法 (RT PCR)检测COX 2和VEGFmRNA的共表达 ,对共表达COX 2和VEGF蛋白和mRNA的肝癌组织进行微血管记数。结果　免疫组织化学检测中 ,48例肝癌组织 3 6例共表达COX 2和VEGF蛋白。类似结果见于蛋白电泳分析。RT PCR显示 ,48例肝癌组织 3 6例共表达COX 2mRNA和VEGFmRNA。两者之间的表达明显相关 (γ =0 .845 )。共表达COX 2和VEGF蛋白和mRNA的肝癌组织中 ,平均微血管数 (5 6.8± 17.5 )个 ,明显高于阴性表达组。结论　COX 2可能与肝细胞癌的血管形成有关 ,且其作用之一可能是通过上调VEGF通道来发挥的
