| 1 | DPSIR Model-Based Evaluation Index System for Geographic National Conditions显示文摘Establishing a reasonable evaluation index system is the basis and premise for the scientific evaluation of geographic national conditions. By analyzing the DPSIR model and its correlation and relation with the evaluation index system, the indexes for geographic national conditions were selected from the aspects of resources, ecology, environment, economy, society, etc to build an evaluation index system for geographic national conditions that consists of three hierarchies: index, criterion, and target levels. Furthermore, the index system was analyzed in terms of index integrity, low overlapping of elements, non-existence of isolated indexes, hierarchy of index system, etc., for the purpose of demonstrating that the DPSIR model-based evaluation index system for geographic national conditions meets the principles of index system establishment. | XIE Mingxia WANG Jiayao YANG Aiming CHEN Ke | 2017 | Wuhan University Journal of Natural Sciences2017，22，5： | 3 |
| 2 | Single-cell transcriptomic landscape of human blood cells显示文摘High throughput single-cell RNA-seq has been successfully implemented to dissect the cellular and molecular features underlying hematopoiesis.However,an elaborate and comprehensive transcriptome reference of the whole blood system is lacking.Here,we profiled the transcriptomes of 7551 human blood cells representing 32 immunophenotypic cell types,including hematopoietic stem cells,progenitors and mature blood cells derived from 21 healthy donors.With high sequencing depth and coverage,we constructed a single-cell transcriptional atlas of blood cells(ABC) on the basis of both protein-coding genes and long noncoding RNAs(lncRNAs),and showed a high consistence between them.Notably,putative lncRNAs and transcription factors regulating hematopoietic cell differentiation were identified.While common transcription factor regulatory networks were activated in neutrophils and monocytes,lymphoid cells dramatically changed their regulatory networks during differentiation.Furthermore,we showed a subset of nucleated erythrocytes actively expressing immune signals,suggesting the existence of erythroid precursors with immune functions.Finally,a web portal offering transcriptome browsing and blood cell type prediction has been established.Thus,our work provides a transcriptional map of human blood cells at single-cell resolution,thereby offering a comprehensive reference for the exploration of physiological and pathological hematopoiesis. | Xiaowei Xie Mengyao Liu Yawen Zhang Bingrui Wang Caiying Zhu Chenchen Wang Qing Li Yingying Huo Jiaojiao Guo Changlu Xu Linping Hu Aiming Pang Shihui Ma Una Wang Wenbin Cao Shulian Chen Qiuling Li Sudong Zhang Xueying Zhao Wen Zhou Hongbo Luo Guoguang Zheng Erlie Jiang Sizhou Feng Lixiang Chen Lihong Shi Hui Cheng Sha Hao Ping Zhu Tao Cheng | 2021 | National Science Review2021，8，3： | 3 |

| 4 | Metabolism of fibrates by cytochrome P450s and UDP-glycosyltransferases in rat and human liver microsomes显示文摘Fibrates are widely used for the treatment of dyslipidemia.However,the contributions of the phase I and phase II metabolic pathways to the clearance of fibrates are unclear.In this study,we investigated the metabolism of gemfibrozil(Gem) ,clofibric acid(CA) ,fenofibric acid(FA) and bezafibrate(Beza) by cytochrome P450s(P450s) and UDP-glycosyltransferases(UGTs) using a substrate depletion approach.We also compared the metabolic characteristics of rat liver microsomes(RLM) and human liver microsomes(HLM) .The intrinsic clearance rates mediated by P450s,UGTs and both were 172 ± 22,643 ± 26,798 ± 103 μL min-1 mg-1,respectively,for Gem and 43 ± 11,88 ± 12,119 ± 15 μL min-1 mg-1,respectively,for CA in RLM.The fractions metabolized by P450s and UGTs in RLM were 22% and 81% for Gem,36% and 74% for CA.The P450-and UGT-mediated depletion rates for Gem were 303 and 1607 nmol min-1 mg-1 in RLM versus 86 and 243 nmol min-1 mg-1 in HLM.The corre-sponding rates for CA were 1.1 and 1.7 nmol min-1 mg-1 in RLM versus 0.025 and 0.038 nmol min-1 mg-1 in HLM.Accordingly,both P450s and UGTs substantially contribute to the clearance of Gem and CA,with UGTs playing a greater role.To avoid un-der-estimating the impact of these pathways,it is necessary to measure NADPH-and UDPGA-dependent metabolism.Although the fractions of these two pathways in RLM and HLM were similar,the depletion rate of Gem and CA in RLM was higher than that in HLM.The metabolism of FA and Beza by P450s and UGTs was too low to calculate intrinsic clearance in both RLM and HLM.These results indicate that fibrates are metabolized via similar pathways in rats and humans,and it is applicable to use RLM to predict the clearance of fibrates in human. | ZHOU YanMi LIU AiMing XIE Hui CHENG Gary Q DAI RenKe | 2012 | Chinese Science Bulletin2012，57，10： | 0 |
| 5 | The Relationship between Serum VEGF Expression and PET/CT Images in TNM-staging of Lung Carcinoma显示文摘OBJECTIVE To analyze the relationship between the characteristics of PET/CT images for lung carcinoma(LC)TNM staging and the expression of serum VEGF protein. METHODS PET/CT examinations were performed before treatment of 53 patients with LC.The expression of serum VEGF protein was examined using a quantitative sandwich enzyme-linked immunosorbent assay(ELISA R and D system).The relationship was analyzed between PET/CT images for LC T-staging and metastasis(lymph nodes and distance)and serum VEGF expression. RESULTS Based on PET/CT images for LC T-staging,11 cases were staged as T1,9 as T2,18 as T3 and 15 as T4.Mediastinal nodal metastases were found in 22 patients,and distance metastasis in 9.The serum VEGF level in the LC patients was(378.02±180.79)ng/L,showing that there was a significant difference between the patients and healthy subjects(P<0.05). There was no significant difference in the level of serum VEGF between different low T-staged(T1,T2)patients.However,the level of serum VEGF was significantly different between the low T-staged(T1,T2)and high T-staged (T3,T4)patients(P<0.05).The level of the serum VEGF protein in the patients with mediastinal nodal metastasis was(561.50±104.55)ng/L,and indicating that there was a statistical significance(t=12.21,P<0.05)compared to those in the non-metastatic group.The level of serum VEGF in the patients with distance metastasis was(614.11±158.81)ng/L,demonstrating that there was a significant difference(t=5.30,P<0.05)compared to those in the nondistant metastatic group. CONCLUSION ① There is a high level of serum VEGF expression in LC patients.②There is a correlation between metastases(lymph nodes and distance)and the level of serum VEGF. ③ With an upgrade of the TNM-stage,the level of serum VEGF protein is elevated. | Zhengping Xiong Yangde Zhang Zhaoyu Liang Aiming Xie Qing He Shuren Yang | 2007 | Chinese Journal of Clinical Oncology2007，4，5： | 0 |
