Surgical strategy of one stage surgery of anterior release combined with posterior correction in treatment of severe scoliosis

Objective: Severe scoliosis refers to scoliosis with serious and stiff curve. It always combins with trunk imbalance in coronal and sagittal contour. Besides complex pathological changes, cardiopulmonary deficits and other concomitant diseases increase treatmental difficulties. So the treatment of severe scoliosis is always a great challenge to spine surgeon. Methods :Thirty-six patients with severe scoliosis received one stage posterior correction followed by anterior release during July 1997 to January 2003, including 9 males and 27 females. Mean age was 17.2 years. Of them, 33 was idiopathic scoliosis and 3 was neurofibromatosis scoliosis( Cobb angle: 85-116 degree); 20 cases were abnormal in sagital plane. Three-dimensional devised instrumentation were applied such as CD, CD-Horizon, TSRH or Isola in posterior procedure followed by anterior release during the same anesthesia. 31 cases of this group received thorac icplasty. Results: The correction in the frontal plane achieved an average of 48.5%. In the sagittal plane, the pathological shape of the spine was reduced and distinctly ameliorated. 80. 6% of the patients maintained or achieved balance of sagittal plane. There were no complications of severe neurological deficit, hook displacement, rod broken, and deep infection at follow-up. One case occurred traumatic pleurisy after operation and another appeared pseudarthrosis 2 years later. One case demonstrated imbalance 11 months after operation. One patient was presented loss of correction more than 10 degree at one year follow-up and 5.2 degree in average. Conclusion:The study indicates that the one stage posterior correction combined with anterior release in treatment of severe scoliosis can achieve satisfactory correction. Appropriate choice of cases, preoperational detailed assessment and application of SEP and wake-up test during operation can possibly reduce severe complication. The long-term outcomes still need further observation.     

乳腺癌ER、c—erbB2及HMGA2的表达及其意义

目的探讨乳腺癌ER、c—erbB2、HMGA2的表达及其临床意义。方法应用免疫组化方法，检测150例乳腺癌ER、c—erbB2、HMGA2表达。结果ER、c—erbB2、HMGA2在乳腺癌的表达率分别为54．2％、45．8％、42．8％；c—erbB2、HMGA2的表达随着组织学分级升高而增加，ER的表达随着组织学分级升高而降低；ER表达与生存期亦未见明确的关系，而c—erbB2、HMGA2阳性表达率与生存期呈负相关。结论ER、c—erbB2、HMGA2对判断乳腺癌分化程度、预后具有价值的指标。     

不同免疫剂治疗扩张型心肌病患儿心功能和临床预后评价

目的观察比较泼尼松联用硫唑嘌呤和大剂量静脉用免疫球蛋白(IVIG)对扩张型心肌病(DCM)患儿心功能及预后的影响。方法将DCM患儿20例分为治疗Ⅰ和Ⅱ组,分别在传统抗心衰治疗基础上加泼尼松联用硫唑嘌呤和大剂量IVIG,治疗1个疗程后评价心功能,检测治疗前后左房横径(LA)、左室舒张期内径(LV)、左室射血分数(LVEF)、心脏指数(CI),并计算其治疗前后变化。所有病例随访1年,计算1年存活率。结果治疗Ⅱ组心功能明显优于治疗Ⅰ组(P均<0.05);两组LA、LV、LVEF和CI治疗后较治疗前均有明显改善(P均<0.05);治疗Ⅰ组各参数变化明显低于治疗Ⅱ组(P均<0.05),其1年存活率明显低于治疗组Ⅱ(P<0.05)。结论泼尼松联用硫唑嘌呤和大剂量IVIG均能改善DCM患儿心功能,但IVIG疗效优于泼尼松联用硫唑嘌呤。     

阿司匹林在预防心脑血管疾病中的应用体会

阿司匹林是人们熟知的传统的解热、镇痛、抗炎药，其药理作用除了退热、抗风湿以外，还有明显的抗血小板聚集的作用，是研究和应用最广泛的抗血栓药物。对减少心脑血管疾病的发生（一级预防）和改善疾病发生后的预后或复发（二级预防）起了不可估量的作用。由于它的价格便宜、作用可靠，目前被广泛应用于防治心脑血管疾病。     

离子交换固相吸收比色法测定海水中铀(Ⅵ)
