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.     

间接免疫荧光法检测婴幼儿急性下呼吸道合胞病毒感染的特异性IgM

本文对1984年1～3月和1985年3～8月共107例急性下呼吸道感染的住院患儿,采用间接免疫荧光法检测其急性期血清抗RSV特异性IgM抗体,并与病毒分离和/或中和试验比较,敏感性为82.1％,特异性为71.8％。RSV感染患儿发病后3天内大多数病例即可从血清中检测出RSV-IgM,因此该法具有早期诊断价值。

静脉预注H1,H2受体阻滞药对减轻鱼精蛋白副作用的研究

将３０例ＡＳＤ、ＶＳＤ患者随机分为对照与预防用药两组，对比观察Ｈ１、Ｈ２受体阻滞药苯海拉明、西米替丁对减轻鱼精蛋白副作用的效果和应用鱼精蛋白后补体Ｃ３、Ｃ４、ＣＨ５０浓度变化。结果发现预防用药组血液动力学变化明显小于对照组，两组之间差异显著（Ｐ＜０．０１）。应用鱼精蛋白后Ｃ３、Ｃ４、ＣＨ５０均下降，与用药前相比差异显著（Ｐ＜０．０１）。提示鱼精蛋白中和肝素可引起补体激活、组胺释放，Ｈ１、Ｈ２受体阻滞药能够减轻鱼精蛋白引起的血压下降。     

Structural vertebral changes in the horizontal plane in idiopathic scoliosis and the long-term corrective effect of spine instrumentation

Summary The rotation and structural changes of the apex vertebra in the horizontal plane as well as of the thoracic cage deformity were quantified by measurements on computed tomography (CT) scans from patients with right convex thoracic idiopathic scoliosis (IS). The CT scans were obtained from 12 patients with moderate scoliosis (mean Cobb angle 25.8°, r 13°–30°) and from 33 with severe scoliosis (mean Cobb angle 46.2°, r 35°–71°). In addition, CT scans of thoracic vertebrae from 15 patients without scoliosis were used as reference material. Ten of the scoliotic cases had had Cotrel-Dubousset instrumentation (CDI) and posterior fusion and had entered a longitudinal study on the effect of operative correction on the re-modelling of the apical vertebra. An increasingly asymmetrical vertebral body, transverse process angle, pedicle width and canal width were found in the groups with scoliosis as compared with the reference material. Vertebral rotation and rib hump index were significantly larger in patients with early and advanced scoliosis than in normal subjects. The modelling angle of the vertebral body, the transverse process angle index and the vertebral rotation in relation to the middle axis of the thoracic cage were significantly greater in patients with severe than with moderate scoliosis. The results of this longitudinal study suggest that the structural changes of the apical vertebra regress 2 years or more after CD instrumentation.     

解磷注射液救治急性有机磷农药中毒34例临床报告

将急性有机磷农药中毒患者69例随机分为2组,一组主要应用解磷注射液治疗(新疗法34例),另一组(35例)主要应用阿托品治疗。两组治愈率分别为97.1％及77.1％,疗效比较差异显著(P<0.05)。新疗法的优点是起效快,作用持久,疗程短(两组比较P<0.001),副反应轻,值得推广应用。并就应用方法及注意事项等作了探讨,也强调了早期足量用药的重要性。

采用双抗体夹心ＥＬＩＳＡ法对３０例正常对照和３６例急性脑梗塞患者血清肿瘤坏死因子（ＴＮＦ）水平进行了检测。结果显示：急性脑梗塞组血清ＴＮＦ水平显著高于正常对照组，血清ＴＮＦ水平变化与脑梗塞容积大小密切相关，恢复期血清ＴＮＦ水平显著降低。结果提示，ＴＮＦ参与了脑梗塞发生后病理变化过程，检测血清ＴＮＦ对判定脑梗塞容积大小有一定的临床意义。     

Adjunctive therapy with bromocriptine in Parkinson's disease

Patients with moderately severe Parkinson's disease complicated by the adverse effects of chronic levodopa use benefited from the addition of bromocriptine (Parlodel; Sandoz) in doses up to 26 mg daily, which allowed an approximate 30% reduction of levodopa dose. This resulted in a significant decrease in the amount of levodopa side-effects while maintaining or improving the original parkinsonian clinical stage. Increased effectiveness in these patients was not associated with increased dosage beyond 25-30 mg daily. When the doses of bromocriptine were increased slowly, the adverse reactions were minor and usually transient.
