Glioma is a common malignant tumor of the central nervous system. Although surgeries, combined with radiotherapy and chemotherapy, can improve patients'quality of life to some extent, the overall survival is still low due to tumor resistance, high mortality and recurrence rates, especially high-grade glioma (HGG), which is the leading cause of death in children and adults with brain tumors. In recent years, with the rise of tumor microenvironment research, it is discovered that tumor tissue and pericellular environment have a large impact on tumor development. This paper reviews the studies related to the neuron-associated tumor microenvironment in promoting glioma progression. [ABSTRACT FROM AUTHOR]

Geospatial data in databases have shifted to conform to the characteristics of big-data in tandem with the development of the Internet，mobile Internet，cloud computing，and especially，spatial data acquisition technologies. Faced with tackling spatial big data， traditional spatial database management techniques based on Relational Database Management Systems have encountered problems including the unstructured characteristics of the spatial object，the high scalability of storage capacity， and the high concurrency in big data application environment. This paper focuses on the mainstream of NoSQL databases that successfully deal with unstructured big data and are widely used in Internet applications ，but lack of spatial characteristics. The data operational and query modes cannot meet the requirments of GIS applications. T o resolve this problem ，this paper proposes a strategy that takes a NoSQL database as a warehouse for spatial big data and a traditional spatial database as the application server. The storage system architecture and the key technology and solutions are discussed. A prototype system was developed based on MongoDB，PostgreSQL and SQ Lite to verify the feasibility and effectiveness of the strategy. [ABSTRACT FROM AUTHOR]

目的 探讨维生素 D(Vit D)营养状态对反复呼吸道感染(RRTI)儿童免疫功能的影响。方法 选取RRTI患儿35例作为观察组,35例健康儿童作为对照组。采用凝集素亲和法检测骨碱性磷酸酶(BALP)、串联质谱法检测25-羟维生素D[25-(OH)D]、散射比浊法检测免疫球蛋白水平,并进行组间比较。观察组给予口服Vit D治疗,2个月后复查免疫球蛋白水平。观察组患儿随访6个月,观察呼吸道感染复发次数。结果观察组与对照组BALP值分别为(231.66±48.59)、(196.37±44.78)U/L,比较差异有统计学意义(t=3.16,P<0.01);其中观察组13例、对照组11例同时行25-(OH)D检测,分别为(25.46±5.01)nmol/L、(65.09±6.64)nmol/L,比较差异有统计学意义(t=16.66,P<0.01);两组Vit D缺乏亚临床状态发生率分别为17.14%(6/35)、14.29%(5/35),差异无统计学意义(χ2=0.11,P>0.05);佝偻病患病率分别为51.43%(18/35)、25.71%(9/35),比较差异有统计学意义(χ2=4.88,P<0.05);观察组治疗前Ig G、Ig A水平均显著低于对照组(t=5.01,P<0.01;t=12.42,P<0.01);观察组治疗后Ig G、Ig A水平均显著高于治疗前(t=3.37,P<0.01;t=8.87,P<0.01);观察组随访6个月,呼吸道感染反复次数为(1.09±0.66)次,较治疗前(4.60±1.44)次明显减少(t=13.14,P<0.01)。结论 Vit D缺乏可使患儿的免疫功能减低,补充足量的Vit D可提高其呼吸道的免疫功能,减少再次患呼吸道感染的概率。 [ABSTRACT FROM AUTHOR]
