The red band and the near-infrared band are often used as sensitive bands for remote sensing retrieval of forest stock volume, however the red edge band between the two is often ignored. To investigate whether the red edge band is sensitive to the accuracy of forest stock volume retrieval, the wide imagery data of GF-6 remote sensing satellite (GF-6 WFV), the DEM, the second survey data of forest resources in 2014 of Xining city were used, and the multiple linear regression model (MLR), the random forest regression model (RF) were employed. The predicting variables were collected from spectral characteristic, vegetation index, topographic factor and image texture. These variables were divided into two groups, the one is no red edge band (No Red-Edge), and the other is red edge band added (Red-Edge Added). The results show that: (1) the selected principal components which were derived from the texture variables of two groups by PCA method mainly explained the texture features of red, near-infrared and red-edge 1 band of the image. (2) Regarding the spectral variables, the surface reflectance of red and near-infrared band were selected because of the high correlation with the forest stock volume in No Red-Edge group, and in Red-Edge Added group, the surface reflectance of the red-edge 1 band was selected. Regarding the vegetation index variables, the Normalized Difference Vegetation Index (NDVI) and Soil Adjusted Vegetation Index (SAVI) were selected in No Red-Edge group, and in Red-Edge Added group, the MERIS Terrestrial Chlorophyll Index (MTCI) was selected. (3) In Red-Edge Added group, the R² of the RF model is better than that of the MLR model, 0.6719 and 0.5487, respectively, and the root mean square error (RMSE) of the RF model is smaller than that of the MLR model, 26.3m³·ha−1 and 20.8m³·ha−1, respectively. (4) After eliminating the effect of the model on the accuracy of forest stock volume retrieval, the R² between the retrieval and the observed values in Red-Edge Added group increased by 11.6%, and the RMSE in Red-Edge Added group decreased by 9.1% compared to No Red-Edge group. Our results suggested that the red-edge band significantly improved the accuracy of the coniferous forest stock volume retrieval in Xining city. This study has high potential value in the remote sensing retrieval of forest stock volume. [ABSTRACT FROM AUTHOR]

Objective To analyze the application effect of thoracoscopic rib tumor resection and traditional open rib tumor resection.Methods A total of thirty-six patients with rib tumors admitted to the thoracic surgery department of the hospital for surgical treatment from June 2020 to January 2021 were retrospectively analyzed and divided into the thoracoscopic group and the open group according to different surgical methods,with 18 cases in each group.The operating time,intraoperative bleeding,postoperative drainage,drainage tube placement time,hospital stay,postoperative pain visual analogue score and postoperative complications occurred in the two groups were compared.Results The amount of intraoperative bleeding,postoperative drainage,duration of drainage tube placement,and pain visual analogue scores at 6,12,24 and 48 hpostoperatively,the incidence of postoperative complications and hospital stay were significantly less in the thoracoscopic group than in the open group,and the differences were statistically significant（P<0.05）.The differences was not statistically significant（P>0.05）;when comparing the operative time between the 2 groups.Conclusion Compared with traditional open-chest rib mass resection,single-operator thoracoscopic rib mass resection has better efficacy and is more valuable for promotion.

The purpose of this study was to explore the structural and expression characteristics of LEA2 genes from Brachymenium exile. BeLEA2 gene was firstly isolated and analyzed by polymerase chain reaction(PCR). The results were as follows:(1)Gene structure analysis showed that BeLEA2 gene contained 2 exons and 1 intron and contained an open reading frame(ORF)of 456 bp encoding a protein of 151 amino acids, and its molecular mass was predicted to be 16 515.96 Da.(2)The phylogenetic analysis of LEA2 with other LEA2 in different plants revealed that BeLEA2 from B. exile and LEA2 from Physcomitrella patens belonged to the same branch of evolutionary distance.(3)The promoter sequence of the BeLEA2 gene of 1 072 bp was isolated from Brachymenium exile by high-efficiency hermal asymmetric interlaced polymerase chain reaction (HiTail-PCR) and analyzed by PlantCARE, the results showed that it had TATA-box, CAAT-box, ABRE, MYB, MYC, MYB binding site and other cis-acting elements.(4)Quantitative real-time PCR analysis indicated that BeLEA2 expressed in different stages and tissues of B. exile, and BeLEA2 responded to dehydration stress. These results lay a foundation for further study on the function of LEA2 gene in bryophytes. [ABSTRACT FROM AUTHOR]

In order to improve the secretion level of endoglucanase from Bacillus subtilis, the promoting factors for the production of endoglucanase by Bacillus subtilis SB13 were screened, and the condition optimization was carried out by orthogonal test. The results showed that MgSO4, VB1, VB2 and soybean polysaccharides all had significant promoting effects on the production of endoglucanase by Bacillus subtilis SB13. The optimal promoting concentrations of each factor for the production of endoglucanase by Bacillus subtilis SB13 were (w/v) ： 0・ 6% MgSO4, 0.2% VB1, 0. 4% VB2, and 0. 8% soybean polysaccharides, respectively. The orthogonal test L9 34 showed that the optimal com bination of enzyme-promoting factors for Bacillus subtilis SB13 was 0. 2% VB1, 0.5% VB2, 1.6% Mg2+, and 0.4% soybean polysaccharides. The optimal promotion temperature was 30 °C and pH value was 7.0. By screening the promoting factors and optimizing the conditions, the activity of endoglucanase produced by Bacillus subtilis SB13 was increased by 200 %, which provided reference for the production and application of Bacillus preparations with high level of endoglucanase.
