Objective The diagnostic efficacy of the two gene methylation indexes was verified by lung biopsy or postoperative disease examination results. Methods A prospective study was conducted to collect 99 patients diagnosed with pulmonary nodules and masses in the Third People's Hospital of Yunnan Province from March 2019 to March 2020. After bronchoscopy and BALF samples were collected, regular follow-up, lung puncture biopsy and post-operative disease examination were performed. Results Ninety-nine patients with pulmonary nodules and masses were divided into lung cancer group (n = 50) and benign lung disease group (n = 49) after pathological diagnosis. The age of patients in the lung cancer group was (62.64±9.71) years, and that of the benign lung disease group was (60.48±13.69) years, and there was a statistical difference between the two groups (P = 0.032). In the diagnosis of lung cancer, the sensitivity and specificity of SHOX2 and RASSF1A genes alone were found to be 72% and 58%, respectively, and 92.3% and 95.9%, respectively. The combined test of the two genes showed a higher sensitivity in the diagnosis of lung cancer, 0.84, compared to 0.102 in the benign disease group (P<0.001). ROC curve analysis showed that the sensitivity of the two genes could be increased to 84% when methylation was combined. Conclusion The methylation test of SHOX2 and RASS1A gene in alveolar lavage fluid has a good value in the diagnosis of lung cancer patients with pulmonary nodules and masses and SHOX2 combined with RASSF1A can be an important supplementary tool for early diagnosis of lung cancer when imaging and histological diagnosis are unclear.

[Objective] The aims of this study are to explore the variation characteristics of runoff and sediment in the main tributaries of Ganjiang River watershed, to quantify the relationship between water and soil conservation measures and sediment transport in the upper reaches of Ganjiang River, and to provide a theoretical basis for soil erosion comprehensive management in Ganjiang River watershed. [Methods] Based on the measured runoff and sediment data of four main tributaries in Ganjiang River watershed from 2011 to 2020, hydrological analysis, cumulative anomaly and double cumulative curve method were used to study runoff and sediment variation. Meanwhile, linear regression analysis was carried out to quantify the relationship between soil and water conservation measures and sediment transport based on the statistical data of soil and water conservation measures in Ganzhou. [Results]（1) Variation trend of rainfall and runoff in the main tributaries of the upper reaches of Ganjiang river was roughly the same. The sediment transport of the main tributaries of the upper Ganjiang River changed with the variation of runoff, presenting a situation of abundant water and abundant sediment, poor water and poor sediment.（2) Sediment discharge in the four basins showed an intermittent trend of increasing（decreasing) and then decreasing（increasing) at two-year or three-year intervals.（3) Linear regression analysis quantified the response of sediment transport modulus to the scale of soil and water conservation measures: Mz=0.019 Swater conservation forest+5.126(Mz representing the annual sediment transport module of Zhangshui, Swater conservation forest representing the annual increase area of soil and water conservation measures in the corresponding tributary watershed).（4) Based on the structure of soil and water conservation measures in Ganzhou, the optimal area proportion of newly incremental water and soil conservation measures was put forward: enclosure management（52.0%～60.0%), fruit forest（22%～25%), water conservation forest（20%～23%), grass planting（2%～3%), slope improvement（2%～3%). [Conclusion] Variation trend of rainfall and runoff in the main tributaries of the upper reaches of Ganjiang river was roughly the same between the year of 2011 and the year of 2020, except the year of 2018. The factors affecting sediment transport of the main tributaries of the upper Ganjiang River are complex. Soil and water conservation measures were the dominant human activities for variation of runoff and sediment load in Zhangshui River Watershed. There was a significant positive correlation between sediment transport modulus and newly increased forest area in Zhangshui River Watershed. [ABSTRACT FROM AUTHOR]

The rise of geographic big data and the advancements in deep learning have brought new opportunities to solve challenges in geospatial analysis. Current methods are rooted in statistical correlations. However, the deceptive and misleading nature of correlation patterns, coupled with inherent biases in the data, make it difficult for those methods to obtain reliable analysis results. And the source of that difficulty is the fact that correlation in data does not imply causation. Serving as the key to unveiling unknown facts and discovering general underlying patterns, causation is critical to geographical research. Given the inherent complexity of earth system and that geographic researches are mainly based on observation into earth, it is impractical to conduct randomized double-blind experiments and inappropriate to directly apply the philosophical definition of causation in geographical researches. In light of that, this paper aims to provide fundamental principles and methodological support for geospatial causal analysis. On the basis of assumptions about geospatial causation, the principle of geospatial causation is proposed. Furthermore, the relationship between this principle and the spatial effects in geospatial analysis is elucidated, major pathways for causal discovery under the consideration of each spatial effect are also presented.

In order to solve the reverse distribution of energy and demand in China, ultra high voltage direct current transmission (UHVDC), which has significant advantages such as large transmission capacity, low line loss and long transmission distance, has become an important scheme. However, due to its long transmission distance, complex terrain and climate across the region, the distribution of soil resistivity along the line is uneven. Based on Zhundong-Wannan ± 1 100 kV UHVDC transmission project, the overvoltage mechanism of DC line was analyzed. The electromagnetic transient calculation software PSCAD was used to simulate and analyze the overvoltage of DC line with different average soil resistivity and actual soil resistivity in four seasons. The results show that the soil resistivity will affect the reflection of the converter station, and the actual soil resistivity will make the maximum overvoltage position shift towards the transmitting side. It is concluded that the overvoltage suppression effect is better by optimizing the installation position of line arrester, which provides an important reference for the development of UHVDC transmission project.

The burden radial distribution in blast furnace influences the profile and location of the cohesive zone formed in the lower part of blast furnace， and thus has considerable impact on process stability and fuel rate. A mathematical model for predicting the layer burden structure in blast furnace was developed and transformed into a software with friendly visual user interfaces for blast furnace operators. The software can be used to calculate the detailed information of the layered burden structure under different charging parameters. The charging parameters include charging matrix， stockline height， charging direction， and radial descending velocity profile of the burden surface. The prediction results include the radial distribution of ore-to-coke ratio， the locatin evolution of burden layers， and the change of layer thickness. These results can provide reference basis for optimization of charging operation. [ABSTRACT FROM AUTHOR]
