磁共振血管成像、虚拟现实技术在蝶骨嵴脑膜瘤术前计划中的应用

目的探讨磁共振血管成像、虚拟现实技术在蝶骨嵴脑膜瘤术前计划中的应用。方法 10例蝶骨嵴脑膜瘤患者术前行头颅CT、MRI和MRA等检查,然后将这些数据输入新加坡Volume Interactions公司研发的Dextroscope术前计划系统,在虚拟现实环境中对肿瘤及其周围组织进行重建等处理,构建出立体的空间三维图像;再利用系统工具对肿瘤及其周围组织进行观察、手术模拟等操作,在术前充分获得肿瘤、颅底骨质及神经、血管等相互关系的信息,制定详细的手术计划,并与术中情况进行对照。结果 10例患者均成功实现了三维立体虚拟现实影像的重建,按照术前计划进行手术,术中情况与术前模拟基本一致,符合率达100%。10例肿瘤均全切,取得良好效果,术后患者无后遗症。结论头颅MRA结合Dextro-scope术前计划系统反映肿瘤及其邻近组织的解剖结构信息,为术前制定手术方案提供帮助,有助于提高手术安全性与病灶切除率,改善患者预后。

糖基化磷脂酰肌醇锚定蛋白质与肿瘤

已经发现有50多种GPI锚定蛋白质与肿瘤关系密切。其中，GPI锚定的癌胚抗原、前列腺特异性抗原、胎盘型碱性磷酸酶等已经作为肿瘤标志物；GPI锚定的CD46，CD55和CD59等参与肿瘤免疫逃逸；GPI锚定的基质金属蛋白酶、T-钙黏着蛋白、CD87等参与肿瘤的侵袭和转移；GPI锚定的CD14，CD16，CD24，CD48和GDNFR—α等能以脂筏的形式介导肿瘤细胞的信息传递。一些细胞因子如IL-2，IL-12等被改造成GPI锚定蛋白质，已试用于肿瘤治疗。     

双钢板垂直和平行放置治疗C型肱骨远端骨折的对比研究

Background Double plate osteosynthesis is the standard treatment for intra-articular fractures of the distal humerus. However, there is still controversy concerning dual plate positions in terms of providing optimal stability. The purpose of this retrospective study was to compare the clinical outcomes in patients with type C intra-articular distal humeral fractures using perpendicular and parallel plating methods.

Methods Between March 2008 and June 2011, a total of 45 patients with type C distal humerus fractures were treated using two different dual plating methods. Of them, 24 patients were treated by perpendicular plating (group I) and 21 patients were treated by parallel plating (group II). The surgical time, blood loss, and union time were compared between the two groups. The flexion-extension arc, the total range of flexion and extension at the end of follow-up were compared between the two groups. The Mayo Elbow Performance Score (MEPS) was used to determine the elbow functional results.

Results All patients were followed up. The mean duration of follow-up was 16 months (range 12–25 months) in group I and 15.5 months in group II (range 12–25 months). There were no significant differences in the surgical time, blood loss, and the bone union time between the two groups. In group I, the mean elbow flexion-extension arc was 101° and the mean MEPS was 85 points. The rate of excellent and good results was 87.5%. In group II, the mean flexion-extension arc was 100° and the mean MEPS was 86.1 points. The rate of excellent and good results was 90.5%. There were no significant differences in the MEPS, flexion-extension arc, and the total range of flexion and extension between the two groups.

Conclusions Perpendicular and parallel plate configurations with the appropriate surgical techniques can provide anatomical reconstruction and stable fixation of type C intra-articular distal humeral fractures and allow early mobilization of the elbow after an operation. The occurrence of post-operative elbow stiffness can be reduced and good outcomes can be obtained.

     

A New Method for Exposing the Animal＇s Heart with Maintenance of Natural Breathing

In the experimental study on the electrophysiology and functions of heart in the animal,the thorax should be opened to expose the heart, at the same time natural breathing is maintained instead of artificial breathing. The key procedure of this new method is to avoid injuring the pleural cavity, so pneumothorax can be prevented. By means of this new method some subject studies have been finished.     

轻度胃肠炎伴婴幼儿良性惊厥的危险因素分析及预警模型建立

目的：探讨影响轻度胃肠炎伴良性婴幼儿惊厥（benign infantile convulsions associated with mild gastroenteritis,BICE）频发（＞3次）的危险因素,建立列线图预测模型,并检验其预测能力。方法：回顾性分析江南大学附属医院2013年10月—2017年12月收治的91例BICE的临床资料,根据惊厥发作次数分为惊厥频发组（＞3次）和对照组（≤3次）,通过Logistic回归分析确定影响惊厥频发的危险因素,并以此构建列线图。采用受试者工作曲线（ROC）及曲线下面积（AUC）、一致性指数（C?in?dex）、校准曲线及决策曲线分析（DCA）对列线图预测能力进行检验。结果：共纳入符合标准的BICE患儿91例,其中惊厥频发组29例,对照组62例,惊厥频发组患儿的CD4+和CD8+T细胞含量明显低于对照组,轮状病毒阳性率、IL?6、IL?10和TNF?α水平明显高于对照组,差异均有统计学意义（P＜0.05）。轮状病毒、CD4+T细胞含量、IL?10和TNF?α水平等是影响BICE患儿惊厥频发的独立危险因素（P＜0.05）。将这4种变量纳入并成功构建列线图。AUC、C?index、校准曲线及DCA分析表明列线图预测效能良好,实际观测有良好的一致性。结论：依据轮状病毒、CD4+T细胞含量、IL?10和TNF?α水平构建的列线图,可较准确地预测BICE患儿惊厥频发,能为临床上惊厥的管理及治疗提供参考。
