以医院登记为基础的20万例恶性肿瘤患者生存报告

背景与目的：恶性肿瘤是全球重大的公共健康问题，患者生存率是评价恶性肿瘤诊治水平的重要指标。通过描述以医院登记为基础的20万例恶性肿瘤患者的生存情况，以真实世界数据从一个侧面反映我国恶性肿瘤的治疗效果。方法：纳入2008年1月1日—2017年12月31日之间在复旦大学附属肿瘤医院确诊为恶性肿瘤并接受住院治疗的患者共计202 542例。通过患者复诊病史资料、电话随访及死因数据链接等方式收集生存随访信息，随访统计时间截至2019年11月30日。应用寿命表法估计各个病种1年、3年和5年总生存率（overall survival，OS），以性别、年龄组、首次治疗时间分层。采用Kaplan-Meier生存曲线绘制各病种的总体生存曲线。结果：患者总体的1年、3年、5年OS分别为89.8%、77.4%和71.0%；男性患者5年OS为58.8%，女性患者为78.7%。在常见的恶性肿瘤中，甲状腺癌患者的5年OS最高，为98.6%；胰腺癌患者最低，为11.4%。2013—2017年首次治疗的乳腺癌、肺癌和肾癌患者5年OS分别为90.0%、55.9%和80.7%，显著高于2008—2012年首次治疗患者，其他肿瘤未见显著上升。结论：大部分恶性肿瘤患者经规范诊治可以获得较为理想的预后，女性生存情况显著优于男性，乳腺癌和肺癌患者的生存改善可能归功于新的临床治疗和早诊手段。     

Outcomes of Early Decompressive Craniectomy Versus Conventional Medical Management After Severe Traumatic Brain Injury: A Systematic Review and Meta-Analysis

This meta-analysis examined whether early decompressive craniectomy (DC) can improve control of intracranial pressure (ICP) and mortality in patients with traumatic brain injury (TBI).Medline, Cochrane, EMBASE, and Google Scholar databases were searched until May 14, 2015, using the following terms: traumatic brain injury, refractory intracranial hypertension, high intracranial pressure, craniectomy, standard care, and medical management. Randomized controlled trials in which patients with TBI received DC and non-DC medical treatments were included.Of the 84 articles identified, 8 studies were selected for review, with 3 randomized controlled trials s having a total of 256 patients (123 DCs, 133 non-DCs) included in the meta-analysis. Patients receiving DC had a significantly greater reduction of ICP and shorter hospital stay. They also seemed to have lower odds of death than patients receiving only medical management, but the P value did not reach significance (pooled odds ratio 0.531, 95% confidence interval 0.209–1.350, Z = 1.95, P = 0.183) with respect to the effect on overall mortality; a separate analysis of 3 retrospective studies yielded a similar result.Whereas DC might effectively reduce ICP and shorten hospital stay in patients with TBI, its effect in decreasing mortality has not reached statistical significance.     

Intermittent Internal Fixation With a Locking Plate to Preserve Epiphyseal Growth Function During Limb-Salvage Surgery in a Child With Osteosarcoma of the Distal Femur: A Case Report

Limb shortening is a problem associated with surgery for osteosarcoma of the lower extremity in adolescents, as the tumors frequently occur near the epiphysis. Herein we report the use of a less invasive stabilization system (LISS) and an intermittent fixation method to preserve the growth function of epiphysis in an 11-year-old patient with an osteosarcoma of the distal femur.The 11-year-old male presented with left knee enlargement and pain for 2 weeks, and magnetic resonance imaging (MRI) and biopsy were consistent with osteosarcoma of the left distal femur. After preoperative chemotherapy, en bloc tumor resection was performed with margins based on MRI findings preserving the epiphyseal growth plate, the tumor cavity was filled with inactivated bone and bone cement, and a LISS was used to stabilize the femur. Aggressive postoperative chemotherapy was given. Approximately 105 weeks after surgery radiography showed that the distal end of the plate had moved superior to the epiphysis along with bone growth. Locking screws were placed in the distal part of the LISS plate to stabilize the re-implanted bone, and external fixation was not needed.The patient was able to walk with the crutches 1 week postoperatively, and bear weight on the extremity 6 weeks postoperatively. At 6 years after surgery, the patient''s height had increased 52 cm, shortening of the affected limb was only 1 cm, and the circumference of the affected limb was 2 cm smaller than that of the contralateral limb. There was no significant discomfort in the affected limb, and there was no gait abnormality. The patient could jump and run, and could participate in sports including basketball and badminton to the same degree as his peers.In summary, the novel method of bone reconstruction and fixation provided good results in a child with an osteosarcoma of the distal femur. This fixation method preserves the osteogenic function of the epiphysis and restored bone integrity simultaneously, and provides good functional recovery.

目的探讨长段复杂性后尿道狭窄治疗新方法。方法采用分期前尿道代后尿道成形术治疗3例复杂性后尿道长段狭窄（6．5—10．0cm）患者。第一期行阴茎转位尿道端端吻合术，术后3—6个月行二期阴茎伸直、尿道会阴造口术，6个月后行第三期前尿道成形术（Johanson Ⅱ期尿道成形术）。结果例1术后排尿通畅，膀胱尿道造影检查示尿道通畅，双侧输尿管返流近消失，最大尿流率18．8ml／s，随访2年，最大尿流率18ml／s，无剩余尿。例2术后排尿通畅，最大尿流率19．5ml／s，无剩余尿，尿道扩张可顺利通过22F尿道探子。例3经会阴一耻骨联合径路行第一期阴茎转位尿道端端吻合术、尿道直肠瘘、尿道会阴瘘切除、修补术，术后尿道直肠瘘及尿道会阴瘘治愈，但因耻骨联合切口感染致吻合口狭窄，有待进一步治疗。结论分期前尿道代后尿道加前尿道重建方法是治疗男性长段复杂性尿道狭窄的有效方法。     

发育期大鼠高热惊厥前后海马γ-氨基丁酸B受体亚基表达的变化

目的：研究高热惊厥(febrile seizures，FS)对发育期大鼠脑内γ-氨基丁酸(γ-aminobutyric acid，GABA)B受体亚基GABABR1与GABARR2蛋白表达的影响。方法：采用热水浴诱导大鼠高热惊厥模型。隔日诱导惊厥1次，共诱导10次，末次惊厥后24h处死大鼠。发育期大鼠随机分为3组：对照组(n＝24)，1次高热处理组(n＝28)，10次高热处理组(n＝40)。高热处理组根据是否出现惊厥再分为1次高热惊厥组(FS1，n＝16)与1次高热未惊厥组(F1，n＝12)，10次高热惊厥组(FS10，n＝15)与10次高热未惊厥组(F10，n＝13)。采用免疫组化方法观察不同次数高热惊厥大鼠脑内GABABR1与GABABR2蛋白表达的变化。结果：FS10大鼠海马齿状回、CAl-CA3区GABABRl和GABABR2蛋白表达明显低于F10、F1、FSl和对照组；F10大鼠上述脑区GABABRl和GABABR2蛋白表达低于F1、FS1和对照组；F1及FS1大鼠与对照组相比差异无显著性；海马各区GABABR1与GABABR2表达的改变大部分平行，但10次高热惊厥后GABABR2在CA1—CA3区下降更明显，而GABABR1在齿状回下降更明显。结论：反复高热惊厥及反复高热均可使发育期大鼠脑内GABABR亚基蛋白表达降低，高热惊厥的影响较单纯高热更为明显，提示GABABR亚单位与发育期大鼠高热惊厥及其脑损伤密切相关。GABABR1与GABABR2改变的不平行可能与受体亚单位组合的可塑性改变有关，这种改变可能导致抑制功能的改变。
