Src kinase inhibitor PP2 regulates the biological characteristics of A549 cells via the PI3K/Akt signaling pathway.

Lung cancer is one of the most prevalent types of cancer worldwide, with a poor prognosis for patients and a concomitant financial burden on society. There are a number of different pathological subtypes, with non-small cell lung cancer (NSCLC) being the primary subtype. Although anticancer therapy has led to a marked improvement in the survival rate of patients in recent years, the survival rate remains poor.

Combined transbronchoscopic needle aspiration (TBNA) and rapid on-site cytological evaluation (ROSE) for diagnosis of tuberculous mediastinal lymphadenitis: A case report.

Introduction: The diagnosis of tuberculous mediastinal lymphadenitis remains a challenge, and the use of transbronchoscopic needle aspiration (TBNA) combined with rapid on-site cytological evaluation (ROSE) is still unclear. A case of tuberculous mediastinal lymphadenitis was illustrated to show the diagnostic value of TBNA and ROSE.

Case Presentation: In this case report, we presented a typical case of a 44-year-old male who underwent obvious odynophagia and mild symptom of dyspnea.

Genotypic distribution of Candida albicans in dental biofilm of Chinese children associated with severe early childhood caries.

Aim: Candida albicans causes a wide range of infections in the oral mucosa, especially candidiasis. A strong association has been found between C. albicans and dental caries.

[Farmland parcel extraction based on high resolution remote sensing image].

A new method of farmland parcel extraction from high resolution remote sensing image based on wavelet and watershed segmentation was proposed in the present paper. First, classification results were used to enhance the contrast of gray-scale value of typical pixels in the original image using the high resolution remote sensing image's spectral information. Second, wavelet transform and watershed segmentation were applied to the enhanced image, then improved region merger algorithm was used to solve the problem of over-segmentation.

[Estimation of vegetation coverage based on an improved sub-pixel model].

Vegetation coverage is an important parameter in terrestrial ecological process, meteorological, and climatic models. By eliminating the errors from the precision of image classification and the noises of remote sensing images, and by using the actual data from fieldwork, this paper determined the maximum and minimum values of normalized difference vegetation index (NDVI), improved the sub-pixel model, and verified this model by calculating the vegetation coverage of Beijing. The results showed that the estimation value of the improved model was very close to the measurements, especially for the herbaceous plants whose vegetation types were the same but the densities were different.

[Biomass structure analysis of Atractylodes lancea in different ecological environments].

Objective: To study the ecological environments of Atractylodes lancea by biomass structural analysis.

Method: Through the scientific investigation in Maoshan, the sampling spots were set up, the relation between growth and ecological environments was researched and the ecological environments of A. lancea were divided as following: the vegetation layer, the shrub layer, the shrub-weed layer and the weed layer.

[Study on dynamical changes of Ginkgo biloba resources in Pizhou city of Jiangsu Province base on RS and GIS].

Objective: To analyse the dynamical changes of the Ginkgo biloba's resources from 2001 to 2006, in Pizhou city, Jiangshu province by useing spatial analytical function of GIS and RS technology.

Method: Use the GIS and RS technology, extracted the information of G. biloba by scientific investigation, researched the spatial distribution and dynamical changes of G.

[Measurement and dynamic analysis of ecological capital of terrestrial ecosystem in China].

Based on remote sensing and ecological principles, an estimation model of ecological capital was established in this paper. The estimation showed that the ecological capital of terrestrial ecosystem in China was 8.148, 10.
