RESUMO

Taking the Xiushui township of Baisha county in Hainan province as the research area,the random forest algorithm with obvious advantages in feature selection and classification extraction was used to extract the information of the Callicarpa nudiflora planting in the study area. Firstly,four kinds of different characteristic variables were generated based on World View-3 data,including spectral features,principal component features,vegetation index and texture features. Secondly,the spatial distribution of the C. nudiflora in the study area was extracted by remote sensing by random forest classification algorithm. Finally,the feature space of the random forest classification algorithm was optimized based on the feature importance to obtain the best random forest classification results,and this result is compared with the classification result of the random forest algorithm of the unoptimized feature space. The results showed that:①The overall accuracy of the C. nudiflora extracted by World View-3 image was 89. 97%,and the Kappa coefficient was 0. 84,which indicates that the random forest algorithm had higher classification accuracy and better applicability in Hainan C. nudiflora recognition.② The overall accuracy of extracting C. nudiflora with the dimension reduction feature was 90. 4,and the Kappa coefficient was 0. 85,which indicates that the random forest algorithm can effectively select features. At the same time as the feature variable data mining,the precision of the information extraction of the C. nudiflora was still guaranteed,and the operation efficiency was improved. This study provides a new idea,method and technical means for information extraction of cultivated medicinal plant resources in terms of feature selection and method selection.

RESUMO

In order to solve the problem of manual area measurement,the traditional methods of medicinal planting area statistics are difficult to meet the needs of rapid area survey application. This paper uses the UAV remote sensing method with the advantages of unmanned,automatic,high efficiency,high score and short production cycle to monitor the shape of Callicarpa nudiflora. A solution for aerial photography,image data acquisition and data processing of drones were designed for characteristics and planting conditions. After data processing and statistical analysis,detailed information on the location and area of the C. nudiflora in the target area was obtained. Then the accuracy comparison analysis was carried out with the measured results of the C. nudiflora. The results show that the UAV is feasible for the monitoring of C. nudiflora,and has a good application prospect in the monitoring of Chinese herbal medicine planting.

RESUMO

In recent years,with deepening research on the division of traditional Chinese medicine,the application of new technologies and new methods have provided support for the division of traditional Chinese medicine. Some relevant scholars have carried out researches on the distribution of some Chinese herbal medicines based on different methods. In this paper,for the same kind of Chinese herbal medicine under different data conditions,we studied the distribution of Polygoni Multiflori Radix by different methods such as qualitative description,similar ecological environment and niche model,and compared the similarities and differences between the distribution results of the same Chinese medicine resources based on different data and methods. The results showed that with the restriction of the researcher's understanding of Chinese herbal medicines and related background data,the zoning results were also in various forms,and there might also be some differences between different zoning results. But in the macroscopic layer,they could reflect the distribution range of Chinese herbal medicines,and they have certain application values to some extent. For example,the study focused on the ancient and modern data and found that with the continuous enrichment of data and information,the understanding of the distribution of Polygoni Multiflori Radix gradually expanded from the southeast coast to the central and southwestern regions to the northwest.But the number of Polygoni Multiflori Radix in the western and northern regions is relatively small than the southeastern regions. The results of relevant zoning can provide scientific basis for carrying out the rational cultivation of Polygoni Multiflori Radix.

RESUMO

The planting area of Chinese medicinal materials is an important basis for formulating policies such as production and poverty alleviation of Chinese medicinal materials and is determining the quantity of medicinal materials trade. Accurately mastering the information of the distribution,area and yield of Chinese medicinal materials cultivation is the basis of the adjustment of the planting structure of traditional Chinese medicine. It is now the largest planting place of Mongolian traditional Chinese medicinal materials in Naiman banner that is belonging to Tongliao city,Inner Mongolia. It is of great significance to obtain the planting area of Mongolian Chinese medicinal materials in Naiman banner in time and effectively for the development of subsequent industries. In this study,Saposhnikovia divaricata,a medicinal plant planted in Naiman banner,was selected as an example,and the fusion 2 m resolution ZY-3 remote sensing image was used as the data source. Based on the ground survey data,the sample data of each typical ground object were selected,and the spectral characteristic curves of different ground objects were obtained,and the S. divaricata spectral information was obtained. Using the filtering texture analysis method based on probability statistics,five kinds of texture image display results under different texture filtering were compared and analyzed,and finally the S. divaricata texture features based on information entropy are determined. The distribution range and planting area of S. divaricata in Naiman banner were extracted and interpreted by using the texture and spectral information of remote sensing images. The results showed that: S. divaricata was mainly distributed in the northeast and central south of Naiman banner,and the planting area was 5 336 mu( 1 mu≈667 m2). The field verification data were in good agreement with the remote sensing interpretation results,and the difference was small. It shows that the combination of spectral information and texture information can realize the discrimination of S. divaricata,and the interpretation results can provide a reference for the county to formulate the poverty alleviation action of Chinese medicinal material industry and the economic development plan of agricultural producing areas.

RESUMO

Due to the large amount of Codonopsis pilosula planted in Weiyuan county,and the arable land area,the local medicinal materials office uses a large amount of manpower,financial resources and material resources to estimate its area every year. In order to extract the information of local Chinese medicinal materials more quickly and simply,we try to apply remote sensing technology to the extraction of Chinese medicinal materials. This paper will use Weiyuan county of Gansu province as the research area,and use the domestic ZY-3 Satellite multi-spectral remote sensing image as the data source to find out the spectral characteristics of the party's participation in other remote sensing images. The visual interpretation method was used to extract the planting area of the C. pilosula in Weiyuan county. The estimated value of the planting area of C. pilosula using satellite remote sensing technology was 75 965 mu( 1 mu≈667 m2),which was basically consistent with the field survey data of the local medicinal materials office. After the accuracy verification,it was found that the precision of C. pilosula planted by visual interpretation was more than 70%. It is concluded that the satellite remote sensing technology can be used to extract the information of C. pilosula and it can provide the relevant information of the planting area of Chinese medicinal materials quickly and accurately.

RESUMO

BACKGROUND Clear cell sarcoma (CCS) of soft tissue, or malignant melanoma of soft parts, is a rare disease. We aimed to identify prognostic factors linked to patient survival in CCS by analyzing demographic and clinical features using the Surveillance, Epidemiology, and End Results (SEER) database. This study aimed to identify prognostic factors associated with CCS that would be of clinical value. MATERIAL AND METHODS We collected data from patients diagnosed with CCS between 1973 and 2009 from the SEER database. The Kaplan-Meier method and Cox regression analysis were performed to identify prognostic factors for patient survival. RESULTS A total of 175 patients with CCS were identified from the SEER database. The 5-year survival rate was 62.9%, and the 10-year survival rate was 51.3%. Patients with CCS with local stage, and with tumor size ≤3 cm were more likely to have good survival rates. CONCLUSIONS The findings from this study showed that the identifiable prognostic factors in patients with CCS were stage and tumor size. Local stage and tumor size ≤3 cm were favorable prognostic factors for patient survival in CCS.

RESUMO

BACKGROUND: Spotted leaf mutants show typical necrotic lesions that appear spontaneously in the absence of any pathogen attack. These mutants are often characterized to exhibit programmed cell death (PCD) and activation of plant defense responses resulting in enhanced disease resistance to multiple pathogens. Here, we reported a novel spotted-leaf mutant, spl40 that showed enhanced disease resistance response. RESULTS: Initially lesions appeared at leaf tips during seedling stage and gradually covered the whole leaf at the tillering stage. The lesion development was light-dependent. spl40 showed obvious cell death at and around the lesion, and burst of reactive oxygen species (ROS) was accompanied by disturbed ROS scavenging system. Photosynthetic capacity was compromised as evidenced by significant reductions in chlorophyll content, important photosynthesis parameters and downregulated expression of photosynthesis-related genes which ultimately led to poor performance of major agronomic traits. spl40 exhibited enhanced resistance to 14 out of 16 races of bacterial blight pathogen of rice, caused by Xanthomonas oryzae pv. oryzae, most probably though activation of SA and JA signaling pathways, owing to upregulated expression of SA and JA signaling genes, though the exact mechanism remain to be elucidated. The spotted-leaf phenotype was controlled by a novel single recessive nuclear gene. Genetic mapping combined with high throughput sequencing analysis identified Os05G0312000 as the most probable candidate gene. Sequencing of ORF revealed a single SNP change from C to T that resulted in non-synonymous change in amino acid residue from leucine to phenylalanine. Interestingly, the complementation plants did not display lesions before heading but showed lesions at the heading stage and the transgenic T1 progenies could be classified into 3 categories based on their lesion intensity, indicating the complex genetic nature of the spl40 mutation. CONCLUSION: The results obtained here clearly show that genes related to defense and PCD were upregulated in accordance with enhanced disease resistance and occurrence of PCD, whereas the photosynthetic capacity and overall ROS homeostasis was compromised in spl40. Our data suggest that a novel spotted-leaf mutant, spl40, would help to elucidate the mechanism behind lesion development involving programmed cell death and associated defense responses.

RESUMO

BACKGROUND: Acute kidney injury (AKI) is a complex clinical disorder with sudden decay in renal function. Ischemia-reperfusion injury (IRI) has been regarded as the main etiology for the occurrence of AKI. MicroRNAs have been consistently shown to be involved AKI. OBJECTIVES: We aimed to investigate the role of miR-155 in AKI and its underlying mechanism. METHODS: Ischemia-reperfusion (I/R)-induced AKI rat model and hypoxia-reoxygeneration (H/R)-induced NRK-52E cell model were established. The concentrations of serum creatinine and blood urea nitrogen were measured to evaluate renal function. Hematoxylin and eosin staining and TUNEL assay were performed to assess the severity of kidney injury. Additionally, quantitative real-time-PCR and western blot analysis were subjected to determine the expression of miR-155, TCF4, and apoptosis-related proteins, respectively. Moreover, cell proliferation and apoptosis were evaluated by Cell Counting Kit-8, bromodeoxyuridine, and flow cytometry analyses, respectively. Luciferase reporter assay was used to validate the direct targeting of TCF4 with miR-155. The protein levels of TCF4 and its downstream proteins in cells were measured by western blot. RESULTS: The expression level of miR-155 was upregulated in both I/R-induced AKI rat model and H/R-treated NRK-52E cells. Moreover, overexpression of miR-155 promoted H/R-induced NRK-52E cells apoptosis and suppressed cell proliferation, while inhibition of miR-155 expression exerted opposite effects. Additionally, TCF4 was identified as a target of miR-155, of which expression was downregulated both in vivo and in vitro. Furthermore, the activity of Wnt/ß-catenin signaling pathway was promoted following overexpression of TCF4 in NRK-52E cells, and this effect was attenuated by the increasing miR-155 expression. CONCLUSION: We demonstrated that miR-155 exacerbated AKI involving the targeting and regulation of TCF4/Wnt/ß-catenin signaling pathway, indicating a novel regulatory network and elucidating a potential target for IRI-induced AKI treatment.

RESUMO

KEY MESSAGE: We demonstrate that the C-terminus of OsCDC48 is essential for maintaining its full ATPase activity and OsCDC48/48E interaction is required to modulate cellular processes and plant survival in rice. Cell division cycle 48 (CDC48) belongs to the superfamily protein of ATPases associated with diverse cellular activities (AAA). We previously isolated a rice CDC48 mutant (psd128) displaying premature senescence and death phenotype. Here, we showed that OsCDC48 (Os03g0151800) interacted with OsCDC48E (Os10g0442600), a homologue of OsCDC48, to control plant survival in rice. OsCDC48E knockout plants exhibited similar behavior to psd128 with premature senescence and plant death. Removal of the C-terminus of OsCDC48 caused altered expression of cell cycle-related genes, changed the percentage of cells in G1 and G2/M phases, and abolished the interaction between OsCDC48 itself and between OsCDC48 and OsCDC48E, respectively. Furthermore, the truncated OsCDC48-PSD128 protein lacking the C-terminal 27 amino acid residues showed a decreased level of ATPase activity. Overexpression of OsCDC48-psd128 resulted in differential expression of AAA-ATPase associated genes leading to increased total ATPase activity, accumulation of reactive oxygen species and decreased plant tiller numbers while overexpression of OsCDC48 also resulted in differential expression of AAA-ATPase associated genes leading to increased total ATPase activity, but increased plant tiller numbers and grain yield, indicating its potential utilization for yield improvement. Our results demonstrated that the C-terminal region of OsCDC48 was essential for maintaining the full ATPase activity and OsCDC48/48E complex might function in form of heteromultimers to modulate cellular processes and plant survival in rice.

RESUMO

Lycii Fructus is a commonly used Chinese herbal medicine. Due to limited wild resources,Lycii Fructus is mainly derived from the cultivation of Lycium barbarum when it circulate in the market. Related studies have shown that there are some differences in the quality of Lycii Fructus from different regions. In August 2017,our research team went to the county areas of Ningxia,Gansu,Qinghai,Xinjiang and Inner Mongolia,which included 13 counties and planted L. barbarum. The county areas obtained 71 batches of samples. According to the content of four chemical components of polysaccharides,protein,vitamins and naringin in 71 batches,the quality of zoning was studied by SPSS and Arc GIS. The results showed that there were significant differences in the contents of polysaccharides,protein,vitamins and naringin in the sampling area. Among them,the vitamin content in Inner Mongolia was relatively high. The content of polysaccharide in Xingjiang was relatively high,the protein content of Ningxia was relatively high. The content of naringin in Inner Mongolia was relatively high. The quality of Lycii Fructus from different producing areas requires a comprehensive evaluation of multiple indicators. Through the analysis of the four chemical components and the eco-environmental factors,the chemical composition with high percentage of percentage content is affected by climatic factors,and the chemical composition with low proportion is greatly affected by soil factors. The literatures such as " Chinese Flora" are mostly recorded that L. barbarum are planted in the northwest and south central areas. There is no record of artificial planting L. barbarum in the northeast region. Through this study,it is found that Liaoning and Jilin province also have a small amount of L. barbarum cultivated. The result shows that in the middle temperature zone and warm temperature zone there are also the cultivation of L. barbarum.

RESUMO

Traditional Chinese medicine (TCM) is not only an effective solution for primary health care, but also a great resource for drug innovation and discovery. To meet the increasing needs for TCM-related data resources, we developed ETCM, an Encyclopedia of Traditional Chinese Medicine. ETCM includes comprehensive and standardized information for the commonly used herbs and formulas of TCM, as well as their ingredients. The herb basic property and quality control standard, formula composition, ingredient drug-likeness, as well as many other information provided by ETCM can serve as a convenient resource for users to obtain thorough information about a herb or a formula. To facilitate functional and mechanistic studies of TCM, ETCM provides predicted target genes of TCM ingredients, herbs, and formulas, according to the chemical fingerprint similarity between TCM ingredients and known drugs. A systematic analysis function is also developed in ETCM, which allows users to explore the relationships or build networks among TCM herbs, formulas,ingredients, gene targets, and related pathways or diseases. ETCM is freely accessible at http://www.nrc.ac.cn:9090/ETCM/. We expect ETCM to develop into a major data warehouse for TCM and to promote TCM related researches and drug development in the future.
