目的:探讨儿童颅骨血管瘤的临床特点和手术治疗。方法:报告自2002年1月至2008年12月我院收治的3例儿童颅骨血管瘤病例,结合相关文献分析该疾病的临床表现,影像学特征,病理特点及治疗方法。结果:儿童颅骨血管瘤临床上极为罕见。影像学检查显示颅骨呈蜂窝状溶骨性改变并向颅内外生长。病理切片显示骨结构异常,并伴有大小不等异常血管增生及血栓形成。结论:颅骨血管瘤是一种侵蚀颅骨内外板的破坏性疾病。手术应早期进行,完整切除后,患者预后良好。
目的：探讨松果体区肿瘤的治疗策略。方法:我院自2003年12月至2007年12月收治的58例松果体区肿瘤，按肿瘤标志物甲胎蛋白（AFP）和人β促绒膜性腺激素（hCG-β）将其分为标志物增高组和正常组，回顾分析两组临床资料和治疗体会。结果:肿瘤标志物正常组36例，其中27例行手术切除肿瘤，9例行伽马刀治疗（其中5例行伽马刀加脑室腹腔分流治疗）。术后4例因病理报告示生殖细胞瘤行伽马刀补充治疗，3例因梗阻性脑积水行脑室腹腔分流。增高组22例，均选用伽马刀治疗（其中17例合并梗阻性脑积水者行伽马刀加脑室腹腔分流）。治疗后3例因症状缓解不佳行手术切除肿瘤术。手术病例中24例采用经胼胝体入路，4例经枕部小脑幕入路，2例经幕下小脑上入路。手术全切24例，次全切5例，部分切除1例，术后住院期内死亡者1例。病理诊断:生殖细胞瘤14例，畸胎瘤5例，中枢神经细胞瘤4例，室管膜瘤2例，表皮样囊肿2例，脑膜瘤1例，胶质瘤1例，皮样囊肿1例。放射外科治疗病例中28例术后3个月临床症状明显改善，4例随访期内肿瘤无明显变化，3例肿瘤增大。2例放疗后出现鞍区转移。结论:松果体区肿瘤组织类型多样，应尽可能先明确肿瘤性质后选择合理治疗策略。
ObjectiveTo review the clinical records of patients with central nervous system (CNS) embryonal tumors, not otherwise specified (NOS); and summarize their clinical features, diagnosis, and treatment.MethodWe reviewed the data of patients with intracranial tumors admitted to Department of Neurosurgery of West China Hospital, Sichuan University from January 2014 to December 2016, and retrospectively analyzed the clinical features, diagnosis, and treatment of seven patients with CNS embryonal tumors, NOS.ResultsThere were 4 males and 3 females, and the mean age was 25.4 years old. The tumor was located in cerebral hemisphere in 5 patients, and in third ventricle in 2. Clinical presentation included headache, nausea, and vomiting due to intracranial hypertension, and focal neurological signs. All patients underwent craniotomy for tumor resection and postoperative pathology confirmed CNS embryonal tumor, NOS. The patients were followed up for 6 months to 3 years, and 2 patients died during follow-up.ConclusionsCNS embryonal tumor, NOS is malignant intracranial lesion, and has been enlisted as a separate entity under classification of CNS embryonal tumors. It has its unique radiological features, including rare occurrence of perilesional edema, cystic changes, and clear demarcation. Through comprehensive treatment including surgical resection, chemotherapy, and radiation therapy, patients can enjoy prolonged survival and improved quality of life.
【摘要】 目的 探讨成人幕上低级别胶质瘤（WHO Ⅱ级）患者术后生活质量的影响因素。 方法 回顾性分析2008年10月—2010年5月经手术切除病变、术后病理证实为低级别胶质瘤的115例患者临床资料，术后随访6~24个月。以患者年龄、性别、主要临床症状、病变部位、病变大小及病理结果为自变量，以术后Karnofsky评分（KPS）改善为因变量，采用Logistic回归分析研究相关影响因素。采用秩和检验比较不同组间KPS差异。 结果 随访至术后6个月，患者年龄、病变大小、病变部位、切除范围以及是否有癫痫史在KPS比较中，其结果有统计学意义（Plt;0.05）。随访至术后12个月，切除范围和癫痫史对KPS评分已无影响（Pgt;0.05）。病理类型、术前是否存在神经功能障碍与术后KPS改善在单因素和多因素比较中无统计学意义。 结论 患者年龄≤50岁、术前有癫痫史、肿瘤直径≤4 cm、病变表浅、肿瘤全切除的患者术后KPS改善好于年龄gt;50岁、术前无癫痫史、肿瘤直径gt;4 cm、病变深在、肿瘤次全切除的患者。患者术前是否存在神经功能障碍和病理类型与术后生活质量是否改善无明显关系。复发也是影响患者术后KPS改善的因素。【Abstract】 Objective To assess the quality of life in adults with surgically managed cerebral supratentorial low grade glioma (WHO grade Ⅱ) and the relevant factors. Methods We retrospectively analyzed the clinical data of 115 patients with histologically proven supratentorial low grade glioma enrolled at West China Hosptial from October 2008 to May 2010. Follow-up lasted for 6 to 24 months after operation. Logisitc regression analysis is used to test the relevant factors with age, gender, main clinical manifestations, lesion location, lesion size and pathological results as the independent variables, and Kamofsky postoperative scale (KPS) scores as dependent variable. KPS scores of different groups were analyzed using the rank test. Results After 6 months of follow-up, we found that age, size, location, extent of surgical excision and eplispy history showed a statistical significance in KPS comparison (Plt;0.05). Till the 12th month in the follow-up, the extent of surgical excision and eplispy history were not statistically significant any more (Pgt;0.05). Histology type and neurological deficit had no relationship with KPS improvement in both single factor analysis and multivariate analysis. Conclusions Patients with an age older than 50 years, preoperative epilepsy history, the largest diameter of the tumor less than 4 cm, shallow lesions, and complete tumor resection have a better KPS improvement after operation than those with corresponding opposite conditions. There is no obvious relationship between histology type, neurologic deficits and KPS improvement after operation. Recurrence is also a factor influencing KPS improvement after operation.
目的 探讨水通道蛋白4（AQP4）在脑胶质瘤性脑水肿的分子调节机制及与血管内皮生长因子（VEGF）的关系。 方法 收集2007年10月-2008年6月间65例脑胶质瘤患者手术切除新鲜肿瘤标本（胶质瘤Ⅰ级6例、Ⅱ级18例、Ⅲ级11例、Ⅳ级30例）。应用免疫荧光细胞化学方法检测肿瘤组织中AQP4蛋白和VEGF蛋白的阳性表达情况，并分析AQP4和VEGF的表达差异与关系。 结果 免疫荧光细胞化学法染色显示，AQP4蛋白在正常脑组织中主要表达于细胞膜表面，胞浆和细胞核着色较浅。在胶质瘤细胞内，AQP4广泛分布于胞浆内；肿瘤中AQP4表达和VEGF呈正相关（r=0.877，P=0.000）。 结论 在胶质瘤性脑水肿中，AQP4在胶质瘤细胞内主要分布于胞浆内，且与VEGF呈明显正相关。
ObjectiveTo systematically review the methodological quality of clinical practice guidelines (CPGs) on the management of acute gastroenteritis/diarrhea in children, then to compare differences and similarities of drug recommendations, in order to provide references for clinical practice. MethodsGuidelines concerning acute gastroenteritis/diarrhea in children were searched in CNKI, VIP, WanFang Data, CBM, PubMed and EMbase databases from inception to April 2015. The websites of GIN (Guidelines International Network), CGC (China Guideline Clearinghouse), NGC (National Guideline Clearinghouse), APP (American Academy of Pediatrics), NICE (National Institute for Health and Clinical Excellence) and the WHO (World Health Organization) were also searched for additional guidelines. The methodological quality of included guidelines were evaluated according to the AGREE Ⅱ instrument, and the differences between recommendations of included guidelines were compared. ResultsA total of 9 guidelines on acute gastroenteritis/diarrhea in children were included. Among them, 3 guidelines were developed by USA, 1 by Malaysia, 1 by EU, 1 by UK, 1 by South Wales, 1 by Australia and 1 by South Africa. Five guidelines were evidence-based guidelines, and the other 4 were non-evidence-based guidelines. The average scores of guidelines in six domains of AGREE Ⅱ were 79% (clarity of presentations), 74% (scope and purpose), 44% (stakeholder involvement), 35% (rigor of development), 32% (applicability), and 30% (editorial independence), respectively. The recommendations of management and treatment were almost consistent. ConclusionThe overall quality of included guidelines was not high. The domain scores of "clarity of presentations" and "scope and purpose" were higher, but the domain scores of "stakeholder involvement", "rigor of development", "applicability" and "editorial independence" needed to be improved. There is still no local guideline of acute gastroenteritis/diarrhea in children in China, so it's urgent to develop guideline that should be suite able for Chinese condition.
