| 1 | Colonization of Penicillium oxalicum SL2 in Pb-contaminated paddy soil and its immobilization effect on soil Pb显示文摘Penicillium oxalicum SL2(SL2) is a previously screened Pb-tolerant fungus that can promote crops growth. The relationship between SL2 colonization and Pb immobilization was studied to provide a theoretical basis for microbial remediation of Pb-contaminated paddy soil.In this study, green fluorescent protein(GFP) labeled SL2 was inoculated into different Pbcontaminated paddy soils(S1-S6). The Pb extracted from the soil by HNO, EDTA and CaClwere used to characterize the available Pb. The results showed that the colonization of SL2was divided into lag phase(0-7 days), growth phase(7-30 days), and mortality phase(30-90days). SL2 colonized well in sandy soils rich in clay and total phosphorus with initial p H of 4.5-7.0. In addition, SL2 increased soil p H and decreased soil Eh, which was beneficial to immobilize Pb. In different soils, the highest percentages of CaCl-Pb, EDTA-Pb, and HNO3-Pb immobilized by SL2 were 34.34%-40.53%, 17.05%-20.11%, and 7.39%-15.62%, respectively.Pearson correlation analysis showed that the percentages of CaCl-Pb and EDTA-Pb immobilized by SL2 were significantly positively correlated with the number of SL2 during the growth phase. SL2 mainly immobilized Pb in the growth phase and a higher peak number of SL2 was beneficial to the immobilization of Pb. | Yu Gao Xiaohan Jiang Hanxin Wu Jianhao Tong Xinyue Ren Jiayu Ren Qianhua Wu Jien Ye Chunhui Li Jiyan Shi | 2022 | Journal of Environmental Sciences2022，34，10： | 1 |

| 4 | Clinical features of multiple myeloma patients with isolated extramedullary relapse显示文摘This study sought to analyze the clinical features and prognosis of multiple myeloma with isolated extramedullary relapse and with the absence of systemic progression.The clinical features and outcome were retrospectively analyzed in six multiple myeloma patients.These patients had secretory multiple myeloma at diagnosis.When relapsed,the dissociation between medullary and extramedullary response was detected.The serum or urine monoclonal component was extremely low or absent.The plasma cells in bone marrow were <5%.All patients received new targeted therapies(thalidomide or bortezomib) before extramedullary relapse.It is difficult to achieve second remission for them.Even in those showing response,the duration of response was extremely short.The median of overall survival from diagnosis and from extramedullary relapse was 19 months and 6 months,respectively.The overall survival was significantly shorter compared to the patients without extramedullary involvement(84 months,P= 0.001).These patients exhibited a special and rare relapse pattern.Patients with this relapse pattern were resistant to current therapies,including novel targeted agents and associated with poor prognosis. | Xiaoyan Qu Lijuan Chen Tian Tian Limin Duan Ruinan Lu Hua Lu Hanxin Wu Jianyong Li | 2018 | The Journal of Biomedical Research2018，32，4： | 0 |
