Current status of glioma therapy / 中国基层医药

Gliomas are a group of refractory heterogeneous diseases. Gliomas even at the same pathological type and grade exhibit different outcomes after treatment. Therefore, glioma patients have obvious survival difference. The development of intraoperative auxiliary means has greatly contributed to surgical resection of glioma and remarkably increased therapeutic effects. The development of sensitizer realizes the combination of radiotherapy and chemotherapy and can improve the anti-tumor effects of oral temozolomide. Molecular markers and signal pathways involved in glioma, such as isocitrate dehydrogenase-1 mutation, epidermal growth factor amplification, high expression of vascular endothelial growth factor, Notch signal pathway, miRNA, etc. are involved in the occurrence and development of glioma and have an obvious impact on the proliferation, metastasis and invasion of glioma. They are potential molecular targets for the clinical treatment of glioma. Many different immunotherapy schemes are actively carried out in patients with glioma, but the unique tumor immune microenvironment of the central nervous system needs to be considered. This paper reviews the treatment progress of glioma in recent years.

Prevalence of iron deficiency anemia and the association with dietary nutrition factors of preschool children in rural Anhui Province / 中国学校卫生

Objective@#To evaluate the dietary quality for preschool children by diet balance index(DBI_C), and to provide an empirical reference for scientific guidance for a reasonable diet and controlling and preventing iron deficiency anemia(IDA).@*Methods@#During September to December of 2018, 306 left behind children and 598 non left behind children aged 3-6 years old of Anhui Province were selected. Four scoring methods (TS Total Score, LBS Low Bound Score, HBS High Bound Score, DQD Diet Quality Distance) were used to evaluate the dietary quality by DBI_C, and multivariate Logistic regression was used to assess the relationship between DBI_C and IDA.@*Results@#The anemia prevalence (AP) was 13.3% among the 3-6 year old children in Anhui rural area, whereas the left behind children (LBC) was 16.7% and the non left behind children was 10.9%, and there was statistical significance of the differences ( χ 2=8.8, P <0.05). There were significant differences of TS[-18.3(25.2，-12.7)，-15.2(-19.8，-8.6)], LBS[25.4(18.3，32.5)，22.7(16.5，30.6)] and DQD[36.8(23.9，43.4)，34.1(27.5，41.0)] in DBI_C scores between anemia group and nonanemia group ( P <0.05). There were significant differences of milk and beans [-5.9(-10.7，-0.4)，-5.0(-8.7，0.2)], animal food [-2.4(-5.6，0.8)，-0.6(3.5，1.9)], food species [-7.5(-9.1，-4.8)，-6.3(-8.0，-2.9)] in food intake scores between anemia group and non anemia group ( P <0.05). Left behind children ( OR =1.27, 95% CI =1.15-1.49) had higher proportions of getting anemia. Meat consumption >3 times per week ( OR =0.81, 95% CI =0.68-0.94) and ≥two types of fresh vegetable consumption every day ( OR =0.84, 95% CI =0.73-0.95) were associated with lower rate of anemia( P <0.05).@*Conclusion@#The AP was relatively high in 3-6 year old children in Anhui rural area, especially in those LBC. Anemia should be reduced by improving the caregivers dietary literacy, increasing intakes of animal foods and fresh vegetables.
