[Objective]To elucidate the main influencing factors of the aesthetic quality of tree forest landscape and reflect the level of tree forest landscape quality in Xinglongshan Nature Reserve. [Method]18 typical plots were set up in 6 types of tree forest landscape forests in Xinglongshan Nature Reserve,Gansu,including pure Pinus tabulaeform is forest,pure Pinus picea forest,and mixed poplar birch forest. On the basis of a comprehensive inspection of the sample plot,the AHP method is used to construct an evaluation index system for the quality and value of the arbor forest landscape. The aesthetic quality of the arbor forest landscape is evaluated,and the comprehensive scores of each landscape type are calculated based on a certain weight. Based on the comprehensive scores,the landscape grade is divided,and the impact of landscape factors on aesthetic quality is analyzed. [Result]The results show that the landscape aesthetic quality of Liaodong oak birch mixed forest,poplar birch mixed forest,and spruce poplar mixed forest in Xinglongshan Nature Reserve,Gansu belongs to level 1,and the landscape aesthetic quality is at a high level;the aesthetic quality of the landscape in the pure forests of Qingqian and Larch belongs to level 2,and the aesthetic quality of the landscape is at an average level;the aesthetic quality of the pure forest landscape of Pinus tabulaeformis belongs to level 3,and the aesthetic quality of the landscape is at a relatively low level. By utilizing relevant knowledge in landscape,ecology,forest cultivation,and horticulture,and taking measures such as thinning,pruning,transplanting,and replanting colorful broad-leaved tree species and other plants,adjusting forest space can effectively improve the landscape quality of tree forests and form a good landscape distribution pattern. [Conclusion] The improvement of the aesthetic quality of tree forest landscape has important practical significance for the development of forest tourism and the protection of resources and environment in Xinglongshan Nature Reserve,Gansu Province.

Objective Through the detection of MIP-1α and VEGF levels in serum and CSF of ALS patients，we evaluated the clinical value of MIP-1 and VEGF levels in ALS patients. Methods A total of 80 patients with ALS were collected from Kuangwu Hospital of Tongchuanin from Jan， 2012 to Jun， 2015， and 67 patients with non-inflammation neurological diseases were chosen as control group. We obtained CSF and serum samples，and the MIP-1α and VEGF levels were measured by ELISA method. Results The MIP-1α levels in serumand CSF of ALS patients were statistically and significantly higher than those in the control group（P ＜0.05） . The VEGF levels in serum of ALS patients were statistically and significantly higher than those in the control group （P ＜0.05） ．The VEGF levels in CSF of ALS patients were not higher than those in the control group，statistically insignificant （P ＞0.05） ．MIP - 1 alpha and VEGF levels was positively correlated with ALS course. The MIP-1αand VEGF levels of the long duration group were greater than the short duration group （P ＜0.05） . Conclusion The rising of MIP-1α and VEGF may indicate an activation of compensatory responses in ALS which suggested that MIP-1 alpha and VEGF are involved in the pathophysiology of amyotrophic lateral sclerosis. We propose that MIP-1α and VEGF may be a useful biomarker witha prognostic and evaluating potential for ALS. [ABSTRACT FROM AUTHOR]

Objective To investigate the association between single nucleotide polymorphisms (SNPs) in IL1RN and risk of glioma. Methods A total of 200 glioma patients and 200 healthy controls were enrolled in Kuangwu Hospital of Tongchuan from January 2012 to December 2016. Blood samples were collected. The genotypes of rs17042888， rs315919， rs928940， rs3181052， rs452204 and rs4252019 were genotyped by MassARRAY method， and the association between SNPs with glioma risk was evaluated using SPSS 19.0. Results Comparing the allele frequencies of SNPs， we found the allele "G" of rs315919 and allele "C" of rs4252019 were significantly associated with decreased risk of glioma (rs315919: OR=0.841， 95%CI: 0.712-0.993，p＝0.041；rs4252019: OR＝0.835， 95%CI: 0.707-0.987，p＝0.034). In the genetic model analysis，we found that under recessive model，carries of G/G genotype of rs315919 have 0.75-fold reduced risk of glioma，compared with carries of T/T and G/T genotypes (OR＝0.75， 95%CI: 0.52-0.96，p＝0.026). Under dominant model， carries of C/T and C/C genotypes of rs4252019 have 0.76-fold reduced risk of glioma， compared with carries of T/T genotype (ORp＝0.76， 95 %CI: 0.59-0.97，p＝0.025). Conclusion The rs315919 and rs4252019 in IL1RN were associated with decreased risk of glioma. [ABSTRACT FROM AUTHOR]
