| 1 | Analysis of the intestinal flora in patientswith primary liver cancer显示文摘Objective To investigate the differences in intestinal flora of patients with primary liver cancer and ofhealthy individuals and to investigate the effect of the differential flora on the development of liver cancer.Methods Overall, 67 patients with primary liver cancer who received systematic and complete treatmentbetween January 2019 and December 2020 at the Sixth People’s Hospital of Qingdao and had completeclinical data were enrolled in this study, and 26 individuals who were healthy on physical examination inthe same period were used as healthy controls. Macro genome and 16s ribosome Deoxyribo Nucleic Acid(rDNA) high-throughput sequencing were performed on the stool flora of the enrolled patients and controls,and the differences in the intestinal flora were analyzed using the LEfSe bioinformatics software.Results Compared with the control samples, all the tested patient samples showed statistically significantdifferences in the number of colonies of 5 bacterial phyla, 5 orders, 8 families, 11 genera, and 14 species(P < 0.05).Conclusion Compared with healthy people, patients with primary liver cancer have significant differencesin the intestinal flora composition. The alteration of the intestinal flora may be correlated with the occurrenceof primary liver cancer, and the intestinal flora may become a novel target for the prevention and treatmentof primary liver cancer. | Chengcong Liu Guoxin Sun Huizhe Wang Gaishuang Shang Xiong Yan Xiao Zou | 2023 | Oncology and Translational Medicine2023，9，1： | 0 |
| 2 | Understanding the drivers of woody plant diversity in urban parks in a snow climate city of China显示文摘Urban parks are an important part of urban ecosystems and play an important role in biodiversity conservation.However,it is still unclear how park characteristics aff ect plant diversity which could hinder the conservation of urban biodiversity due to the ineff ective design of urban parks.The diversity of woody plants in 33 parks of Changchun,China,was measured with plot measurements and linked with urban park characteristics(e.g.,size and age of the park)to uncover the relationship between them.The results show that urban woody plant species were abundant,with 98 species belonging to 51 genera and 26 families in the snow climate city of Changchun.The variation in woody plant diversity was largely explained by internal patch characteristics(e.g.,size,age,shape),and external factors surrounding the park(e.g.,land use type and socioeconomic level)accounted for only 16.0%in our study.For internal patch characteristics,older urban parks with larger areas demonstrated a richer level of plant diversity and increased nonlinearly with increasing park area.The threshold size signifi cantly aff ecting plant diversity variation was approximately 30 ha.Plant diversity had positive linear relationships with the ages of urban parks,supporting the legacy eff ect.In addition,woody plant diversity nonlinearly decreased with increasing park shape index,which suggested that the plant diversity could also be increased by optimizing the park shape.Regarding the external factors surrounding parks,the spatial distribution of woody plant diversity varied greatly from the urban center to the suburbs.House prices around the park had positive linear relationships with woody plant diversity in parks,supporting the luxury eff ect.However,building and road proportions,and green space proportion had no relationship with plant diversity in parks.This study can provide a robust reference for enriching plant diversity in urban parks,thus improving the development of urban sustainable cities. | Zijun Ma Peng Zhang Nanlin Hu Guodong Wang Yulin Dong Yujie Guo Chengcong Wang Yao Fu Zhibin Ren | 2023 | Journal of Forestry Research2023，34，4： | 0 |
