2Management of cytokine release syndrome related to CAR-T cell therapy显示文摘Chimeric antigen receptor T (CAR-T) cell therapy is a novel cellular immunotherapy that is widely used to treat hematological malignancies, including acute leukemia, lymphoma, and multiple myeloma. Despite its remarkable clinical effects, this therapy has side effects that cannot be underestimated. Cytokine release syndrome (CRS) is one of the most clinically important and potentially life-threatening toxicities. This syndrome is a systemic immune storm that involves the mass cytokines releasing by activated immune cells. This phenomenon causes multisystem damages and sometimes even death. In this study, we reported the management of a patient with recurrent and refractory multiple myeloma and three patients with acute lymphocytic leukemia who suffered CRS during CAR-T treatment. The early application of tocilizumab, an anti-IL-6 receptor antibody, according to toxicity grading and clinical manifestation is recommended especially for patients who suffer continuous hyperpyrexia, hypotensive shock, acute respiratory failure, and whose CRS toxicities deteriorated rapidly. Moreover, low doses of dexamethasone (5-10 mg/day) were used for refractory CRS not responding to tocilizumab. The effective management of the toxicities associated with CRS will bring additional survival opportunities and improve the quality of life for patients with cancer.Hongli Chen Fangxia Wang Pengyu Zhang Yilin Zhang Yinxia Chen Xiaohu Fan Xingmei Cao Jie Liu Yun Yang Baiyan Wang Bo Lei Liufang Gu Ju Bai Lili Wei Ruili Zhang Qiuchuan Zhuang Wanggang Zhang Wanhong Zhao Aili He 2019Frontiers of Medicine2019,13,5:21

4Comparsion analysis of data mining models applied to clinical research in Traditional Chinese Medicine显示文摘OBJECTIVE: To help researchers selecting appropriate data mining models to provide better evidence for the clinical practice of Traditional Chinese Medicine(TCM) diagnosis and therapy.METHODS: Clinical issues based on data mining models were comprehensively summarized from four significant elements of the clinical studies:symptoms, symptom patterns, herbs, and efficacy.Existing problems were further generalized to determine the relevant factors of the performance of data mining models, e.g. data type, samples, parameters, variable labels. Combining these relevant factors, the TCM clinical data features were compared with regards to statistical characters and informatics properties. Data models were compared simultaneously from the view of applied conditions and suitable scopes.RESULTS: The main application problems were the inconsistent data type and the small samples for the used data mining models, which caused the inappropriate results, even the mistake results. These features, i.e. advantages, disadvantages, satisfied data types, tasks of data mining, and the TCM issues, were summarized and compared.CONCLUSION: By aiming at the special features of different data mining models, the clinical doctors could select the suitable data mining models to resolve the TCM problem.Yufeng Zhao Qi Xie Liyun He Baoyan Liu Kun Li Xiang Zhang Wenjing Bai Lin Luo Xianghong Jing Ruili Huo 2014Journal of Traditional Chinese Medicine2014,34,5:14

6Dietary supplementation with Clostridium butyricum improves growth performance of broilers by regulating intestinal microbiota and mucosal epithelial cells显示文摘Clostridium butyricum has been widely considered an antibiotic substitute in recent years.It can promote growth performance,improve the immune response and enhance the intestinal barrier function of the host.In the present study,1-d-old Arbor Acres(AA)broilers were fed C.butyricum(1×109 cfu/kg)for 28 d.The transcriptomic characteristics of epithelial cells of the cecal mucosa were determined by RNA-sequence,and the cecal microbiota composition was explored by 16 S ribosomal RNA gene sequencing.The changes in the intestinal mucosa of broilers were then analyzed by tissue staining.Gene Ontology(GO)annotations identified substance transport and processes and pathways that might participate in intestinal development and cell viability.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis revealed that the differentially expressed genes are involved in numerous pathways related to amino acid and vitamin metabolism and antioxidant and defensive functions,among others.The relative expression of some genes associated with intestinal barrier function(claudins 2,15,19,and 23,tight junction proteins 1,2,and 3 and mucin 1)was significantly increased in the treatment group(P<0.05 or P<0.01).Moreover,the proportion of Firmicutes was higher in the C.butyricum-treated group,whereas the proportion of Proteobacteria was higher in the control group.At the genus level,the relative abundances of Butyricicoccus and Lactobacillus,among other bacteria,were increased after C.butyricum supplementation.The tissue staining analysis showed that the cecal mucosa of broilers was significantly ameliorated after the addition of C.butyricum(P<0.05 or P<0.01).These results showed that dietary supplementation with C.butyricum can enhance the antioxidant capacity,mucosal barrier function,and stabilize the cecal microbiota,resulting in improving the growth performance.Laipeng Xu Xiangli Sun Xianhua Wan Keke Li Fuchun Jian Wenting Li Ruirui Jiang Ruili Han Hong Li Xiangtao Kang Yanbin Wang 2021Animal Nutrition2021,,4:12

9Nanostructured ultrathin catalyst layer with ordered platinum nanotube arrays for polymer electrolyte membrane fuel cells显示文摘Fabrication of novel electrode architectures with nanostructured ultrathin catalyst layers is an effective strategy to improve catalyst utilization and enhance mass transport for polymer electrolyte membrane fuel cells (PEMFCs).Herein,we report the design and construction of a nanostructured ultrathin catalyst layer with ordered Pt nanotube arrays,which were obtained by a hard-template strategy based on ZnO,via hydrothermal synthesis and magnetron sputtering for PEMFC application.Because of the crystallographically preferential growth of Pt (111) facets,which was attributed to the structural effects of ZnO nanoarrays on the Pt nanotubes,the catalyst layers exhibit obviously higher electrochemical activity with remarkable enhancement of specific activity and mass transport compared with the state-of-the-art randomly distributed Pt/C catalyst layer.The PEMFC fabricated with the as-prepared catalyst layer composed of optimized Pt nanotubes with an average diameter of 90(±10) nm shows excellent performance with a peak power density of 6.0W/mgPt at 1 A/cm^2,which is 11.6%greater than that of the conventional Pt/C electrode.Ruoyi Deng Zhangxun Xia Ruili Sun Suli Wang Gongquan Sun 2020Journal of Energy Chemistry2020,29,4:8

11Spider web-like carbonized bacterial cellulose/MoSe_(2) nanocomposite with enhanced microwave attenuation performance and tunable absorption bands显示文摘It is essential to manufacture microwave absorbers with strong absorption as well as tunable absorption bands at a low filler content.However,it remains challenging for pure biomass material to reach this goal without loading other components.MoSe_(2),as a transition metal chalcogenide with semiconductor properties,has emerged as a potential microwave absorber filler.Herein,bacterial cellulose(BC)-derived carbon nanofibers/MoSe_(2) nanocomposite was fabricated and phosphoric acid was used to dope phosphorus in BC,in which MoSe_(2) microspheres were dropped on the BC network like a dew-covered spider web.This unique network structure enhances conductive loss and multiple reflections of the incident wave.The collocation of BC and MoSe_(2) is helpful to impedance match and introduces interfacial/dipolar polarization loss;moreover,the P-doping of BC helps to tune the absorption bands.Overall,the optimal reflection loss of undoped one reaches−53.33 dB with only 20 wt.%filler content,whose main absorption peaks focus on X-band.Interestingly,after the P-doping of BC,the main absorption peaks move to Ku-band and the optimal reflection loss gets stronger(−66.84 dB)with the same filler loading.Strong absorption and tunable absorption bands can be realized,and thus wide frequency range is covered.This work is expected to enlighten future exploration of biomass carbon materials on high-performance microwave absorption materials.Zhengjian Xu Man He Yuming Zhou Shuangxi Nie Yongjuan Wang Yao Huo Yifan Kang Ruili Wang Ran Xu Hao Peng Xi Chen 2021Nano Research2021,14,3:6
12Characterization of aroma compounds of Pu-erh ripen tea using solvent assisted flavor evaporation coupled with gas chromatography-mass spectrometry and gas chromatography-olfactometry显示文摘Pu-erh ripen tea becomes popular worldwide owing to its unique taste and aroma.In the present study,volatile compounds from Pu-erh ripen tea were extracted using a solvent assisted flavor evaporation(SAFE)and analyzed with a gas chromatography-mass spectrometry(GC-MS)and a gas chromatography olfactometry(GC-O).Results demonstrated that 58 major volatile compounds and 24 aroma active substances of Pu-erh ripen tea were identified by GC-MS and GC-O analysis.Among volatile compounds identified,methoxyphenyl compounds were considered as the dominate compounds in the aroma of Pu-erh ripen tea.Further investigation showed that 6 methoxybenzenes were responsible for the aging aroma in Pu-erh ripen tea;α-ionone,3,4-dimethoxytoluene,1,3-dimethoxybenzene,etc.were responsible for the wood-like aroma.Linalool,α-terpineol,α-ionone,β-ionone,and benzeneacetaldehyde were responsible for the floral odor.Compared the odor detection threshold(ODT)among the 8 methoxyphenyl compounds in water,1,2,3-trimethoxybenzene showed the highest ODT,followed by 3,4-dimethoxyphenol.1,3-dimethoxybenzene(105μg/L)and 1,2,3-trimethoxy-5-methylbenzene(100μg/L)were present at relatively low odor threshold values.The result indicated that methoxyphenyl compounds play a vital role in the unique flavor of Pu-erh ripen tea.Bei Wang Qing Meng Lin Xiao Ruili Li Chunhai Peng Xueli Liao Jingna Yan Honglin Liu Guanhua Xie Chi-Tang Ho Huarong Tong 2022Food Science and Human Wellness2022,11,3:6
13HMW glutenin subunits in multiploid Aegilops species: composition analysis and molecular cloning of coding sequences显示文摘The Aegilops genus contains species closely related to wheat. In common with wheat, Aegilops species accumulate high molecular weight (HMW) glutenin subunits in their endospermic tissue. In this study, we investigated the composition of HMW glutenin subunits in four multiploid Aegilops species using SDS-PAGE analysis. Furthermore, by working with Ae. ventricosa, we established an efficient ge-nomic PCR condition for simultaneous amplification of DNA sequences coding for either x- or y-type HMW glutenin sub-units from polyploid Aegilops species. Using the genomic PCR condition, we amplified and subsequently cloned two DNA fragments that may code for HMW glutenin subunits in Ae. ventricosa. Based on an analysis of the deduced amino acid sequences, we concluded that the two cloned sequences encode one x- and one y-type of HMW glutenin subunit, respectively.Ruili Xie Yongfang Wan Yan Zhang Daowen Wang 2001Chinese Science Bulletin2001,46,4:6
14Incorporating the magnetic alignment of GO composites into Pebax matrix for gas separation显示文摘The mixed matrix membranes(MMMs) were developed by incorporating graphite oxide(GO) flakes functionalized with iron oxide(Fe_3O_4) into Pebax matrix. The Pebax/Fe_3O_4–GO MMMs were used to separate CO_2/CH_4 and CO_2/N_2 gas mixture. The results showed that the MMMs with magnetic alignment presented the better gas separation performance than that of random arrangement of Pebax/Fe_3O_4–GO mixed matrix membranes. The reason was that the Fe_3O_4–GO flakes arranged magnetically in the membrane played a multiple role in improving the performance of MMMs. Firstly, under the action of the magnetic field,the magnetic alignment of Fe_3O_4–GO flakes in Pebax matrix constructed the shorter transfer path for gas molecule, increasing the CO_2 permeability. Secondly, the hydroxyl groups in GO flakes and the presence of Fe_3O_4 have stronger binding force for water, improving the CO_2 solubility selectivity. Thirdly, the better interaction between the magnetic alignment of GO composites and polymer matrix, reduced the interface defects. Especially, the optimum gas separation performance was obtained at the Fe_3O_4–GO flakes content of 3 wt% in Pebax matrix at vertical arrangement with selectivity of 47 and 75 for CO_2/CH_4 and CO_2/N_2, respectively, and CO_2 permeability of 538 Barrer at 0.2 MPa and room temperature.Weifang Zhu Yun Qin Zhongming Wang Jianshu Zhang Ruili Guo Xueqin Li 2019Journal of Energy Chemistry2019,28,4:5
15Germination and early seedling growth of Pinus densata Mast.provenances显示文摘We studied seed germination and early seedling growth of Pinus densata to explore the range of variability within the species and to inform afforestation practices.Phenotypes were evaluated at a forest tree nursery under conditions that support Pinus yunnanensis, one of the presumed parental species of P. densata. Seeds were collected from 20 open-pollinated trees within each of eight autochthonous populations representing the natural distribution of P. densata in China to assess variation in germination traits and early seedling growth, and to examine the relationships among these traits. Results showed that seeds from all populations germinated and seedlings established successfully. There were significant differences among populations in 13 of 14 traits evaluated. Seed germination and early seedling growth were strongly related to seed size and seed weight. Bigger seeds germinated earlier and faster than small seeds, and seedling size was positively correlated with seed size. Some germination traits were strongly and significantly correlated with climatic variables associated with the provenance of the studied populations. Based on these observations, we conclude there were large, significant, and biologically important differences among P. densata populations in seed germination and seedling growth traits. The observed variability probably reflects a high degree of adaptive differentiation among populations that is likely to be relevant for future afforestation.Yulan Xu Nianhui Cai Bin He Ruili Zhang Wei Zhao Jianfeng Mao Anan Duan Yue Li Keith Woeste 2016Journal of Forestry Research2016,27,2:5
16Novel Ag nanocrystals based dental resin composites with enhanced mechanical and antibacterial properties显示文摘The aim of this work was to investigate the effect of trace addition of oleic acid coated Ag nanocrystals(Ag NCs) on mechanical and antibacterial properties of dental resin composites.Composites(70 wt%of silica loading) with 25 ppm,50 ppm,75 ppm and 100 ppm(wt) Ag NCs were prepared and the composite without Ag NCs served as a control.The experimental results showed that the addition of Ag NCs significantly improved the strength and modulus of the resin composite without compromising the shade.For the composite with 50 ppm Ag NCs,fiexural strength(140.3 MPa),modulus(13.2 GPa)and compressive strength(347.2 MPa) were increased by 4.1%,22.2%,13.3%,respectively,compared with the control.The antibacterial test demonstrated that trace Ag NCs provided the resin composites with an antibacterial effect.Such strong and antibacterial dental resin composites might be advantageous to prevent secondary caries and be potential for future clinical applications.Fengwei Liu Ruili Wang Yuyuan Shi Xiaoze Jiang Bin Sun Meifang Zhu 2013Progress in Natural Science:Materials International2013,23,6:5
17Biodistribution of fullerene derivative C_(60)(OH)_x(O)_y显示文摘The biological behavior of fullerene derivatives shows their considerable potential application in medicine field. To understand the biodistribution of C60 derivatives as drugs or drug carriers, a simple water-soluble derivative C60(OH)x(O)y was labeled with 99mTc. A r-counter and a single photo emission computed tomography (SPECT) were used to assess the biodistribution and metabolism of the labeled compound in mice and rabbits, respectively. The results showed that the compound could be absorbed rapidly by tissues, especially by coronal bone, breastbone, backbone, extremity honeycomb, liver and spleen. The clearance was slow from all tissues except for brain. The compound might be excreted through urine and enteron. The biodistribution shows some difference from that of Yamago et al. In this note, we discuss the possible reason leading to the difference. Further study is needed to find out to what extent the C60 itself determines the biodistribution of derivatives.LI Qingnuan, XIU Yan, ZHANG Xiaodong, LIU Ruili, DU Qianqian, SUN Xiaoguang, CHEN Shaoliang & LI Wenxin1.

18Effect of acupuncture at Renying(ST 9) on gene expression profile of hypothalamus in spontaneously hypertensive rats显示文摘OBJECTIVE: To investigate changes in gene expression profiles in the hypothalamus related to the effects of acupuncture at the Renying(ST 9) acupoint in spontaneously hypertensive(SH) rats.METHODS: We randomly divided 18 SH rats into Renying(ST 9) group and model control group, 9 body weight-matched Wistar-Kyoto rats were used as blank controls. Acupuncture was performed manually for 20-min daily over 28 d in the Renying(ST 9) group. Rat Gene 2.0 array technology was used for the determination of gene expression profiles and the screened key genes were verified by real-time quantitative polymerase chain reaction(RT-PCR) analyses.RESULTS: The different groups exhibited differential gene expression: compared with the blank control group, 48 genes were up-regulated and 91 genes were down-regulated in the model group;compared with the model group, 79 genes were up-regulated and 80 genes were down-regulated in Renying(ST 9) group. The RT-PCR results of the key genes including Chi3 l1, Ephx2, Klk1, 5-HT1 A and Cbs were consistent with that of gene chip analysis.CONCLUTION: Acupuncture at Renying(ST 9)could significantly lower the blood pressure of SH rats and affect their hypothalamic gene expression profile. Genes associated with the contraction of vascular smooth muscle and the regulation of inflammation, neurotransmitters may be involved in acupuncture's antihypertensive mechanism.Guo Yan Lu Juan Liang Jingrong Zhao Ruili Xu Jing Zhang Wei Park Kibeum Zhu Shipeng Chen Huan Ma Liangxiao 2018Journal of Traditional Chinese Medicine2018,38,2:4
19Identification of novel QTL associated with soybean isoflavone content显示文摘Soybean isoflavones are essential secondary metabolites synthesized in the phenylpropanoid pathway and benefit human health. In the present study, highresolution QTL mapping for isoflavone components was performed using specific-locus amplified fragment sequencing(SLAF-seq) with a recombinant inbred line(RIL) population(F5:7) derived from a cross between two cultivated soybean varieties, Luheidou 2(LHD2) and Nanhuizao(NHZ). Using a high-density genetic map comprising 3541 SLAF markers and the isoflavone contents of soybean seeds in the 200 lines in four environments, 24 stable QTL were identified for isoflavone components, explaining 4.2%–21.2% of phenotypic variation.Of these QTL, four novel stable QTL(qG8, qMD19, qMG18, and qTIF19) were identified for genistin, malonyldaidzin, malonylgenistin, and total isoflavones, respectively. Gene annotation revealed three genes involved in isoflavone biosynthesis(Gm4CL, GmIFR, and GmCHR) and 13 MYB-like genes within genomic regions corresponding to stable QTL intervals, suggesting candidate genes underlying these loci. Nine epistatic QTL were identified for isoflavone components, explaining 4.7%–15.6% of phenotypic variation. These results will facilitate understanding the genetic basis of isoflavone accumulation in soybean seeds. The stable QTL and tightly linked SLAF markers may be used for markerassisted selection in soybean breeding programs.Ruili Pei Jingying Zhang Ling Tian Shengrui Zhang Fenxia Han Shurong Yan Lianzheng Wang Bin Li Junming Sun 2018The Crop Journal2018,6,3:3
20Luminous composite ultrathin films of CdTe quantum dots/silk fibroin co-assembled with layered doubled hydroxide:Enhanced photoluminescence and biosensor application显示文摘Quantum dots(QDs)luminescent films are extensively applied to optoelectronics and optical devices.However,QDs aggregation results in the quenching of their fluorescence property which limits their practical applications to a greater extent.In order to resolve this issue,3-mercaptopropionic acid(3-MPA)functionalized Cadmium Tellurium(CdTe)QDs were stabilized by silk fibroin(SB)and coassembled with layered doubled hydroxide(LDH)to form(QDs@SF/LDH)_(n)ultrathin films(UTFs)via the layer-by-layer(LBL)technique.UV-Vis absorption and fluorescence spectroscopy showed a stepwise and normal growth of the films upon increasing the number of deposition cycles.XRD and AFM studies confirmed the formation of a periodic layered structure and regular surface morphology of the thin films.As compared to(CdTe QDs/LDH)_(n)UTFs,the(CdTe QDs@SF/LDH)_(n)UTFs displayed fluorescence enhancement and longer fluorescent lifetime,both in solid states and aqueous solutions.Furthermore compared with the solution state,the fluorescence enhancement of SF-RC and SF-β are,respectively,7 times and 17 times in the(CdTe QDs@SF/LDH)_(n)UTFs,indicating that the LDH nanosheets favor the fluorescence enhancement effect on the CdTe QDs@SF.The fabricated materials displayed fluorescence response to a biological molecule such as immune globulin,lgG.Thus,the(CdTe QDs@SF/LDH)_(n)UTFs has a potential to be used as biosensor.Muhammad Sohail Haroone Ling Li Aftab Ahmad Yaping Huang Ruili Ma Ping Zhang Yuehua Hu Qari Muhammad Kaleem Jun Lu 2018Journal of Materiomics2018,4,2:3
