1The Reference Genome of Tea Plant and Resequencing of 81 Diverse Accessions Provide Insights into Its Genome Evolution and Adaptation显示文摘Tea plant is an important economic crop,which is used to produce the world's oldest and most widely consumed tea beverages.Here,we present a high-quality reference genome assembly of the tea plant(Camellia sinensis var.sinensis)consisting of 15 pseudo-chromosomes.LTR retrotransposons(LTR-RTs)account for 70.38%of the genome,and we present evidence that LTR-RTS play critical roles in genome size expansion and the transcriptional diversification of tea plant genes through preferential insertion in promoter regions and introns.Genes,particularly those coding for terpene biosynthesis pro-teins,associated with tea aroma and stress resistance were significantly amplified through recent tandem duplications and exist as gene clusters in tea plant genome.Phylogenetic analysis of the sequences of 81 tea plant accessions with diverse origins revealed three well-differentiated tea plant populations,support-ing the proposition for the southwest origin of the Chinese cultivated tea plant and its later spread to western Asia through introduction.Domestication and modern breeding left significant signatures on hundreds of genes in the tea plant genome,particularly those associated with tea quality and stress resis-tance.The genomic sequences of the reported reference and resequenced tea plant accessions provide valuable resources for future functional genomics study and molecular breeding of improved cul-tivars of tea plants.Enhua Xia Wei Tong Yan Hou Yanlin An Linbo Chen Qiong Wu Yunlong Liu Jie Yu Fangdong Li Ruopei Li Penghui Li Huijuan Zhao Ruoheng Ge Jin Huang Ali Inayat Mallano Yanrui Zhang Shengrui Liu Weiwei Deng Chuankui Song Zhaoliang Zhang Jian Zhao Shu Wei Zhengzhu Zhang Tao Xia Chaoling Wei Xiaochun Wan 2020Molecular Plant2020,13,7:51

4Prevalence of Thyroid Nodules and Its Relationship with Iodine Status in Shanghai:a Population-based Study显示文摘Objective This study was designed to evaluate the prevalence of thyroid nodules(TNs) and its relationship with urine iodine concentrations(UICs) after the regional rapid economic growth and lifestyle changes. Methods A cross-sectional survey was conducted in the general population aged 15-69 years. A questionnaire regarding general and personal characteristics and relevant information was administered. Ultrasonography of the thyroid was performed, and serum triiodothyronine(T3), tetraiodothyronine(T4), serum thyroid stimulating hormone(TSH), free triiodothyronine(FT3), free tetraiodothyronine(FT4), thyroglobulin antibody(Tg Ab), thyroid peroxidase antibody(TPOAb), and TSH receptor antibody(TRAb) levels were measured for each individual subject. Results The prevalence rates of TNs in the whole population, females and males were 27.76%, 34.04%, and 21.60%, respectively. The prevalence of multiple nodules increased with age, whereas the prevalence peaks differed between males and females. The median UICs in the whole population and females with non-TNs were higher than those of subjects with TNs(P=0.0035, P=0.0068). The median UICs in subjects with a single TN were higher than those in subjects with multiple TNs(P=0.0164, P=0.0127). The result showed a U-shaped curve relationship between UIC and prevalence of TNs. The prevalence of TNs was the lowest when the UIC was 140-400 μg/L. Conclusion The prevalence of TNs was nearly 30% and increased with age. The relationship between UIC and prevalence of TNs is U-shaped, with an increase in risk when the UIC was <140 μg/L and >400 μg/L. Very low or high UIC levels need attention and correction.SONG Jun ZOU Shu Rong GUO Chang Yi ZANG Jia Jie ZHU Zhen Ni MI Ming HUANG Cui Hua YU Hui Ting LU Xi RUAN Ye WU Fan 2016Biomedical and Environmental Sciences2016,29,6:25

6A novel gene delivery system targeting cells expressing VEGF receptors显示文摘Two ligand oligopeptides GV1 and GV2 were designed according to the putative binding region of VEGF to its receptors. GV1, GV2 and endosome releasing oligopeptide HA20 were conjugated with poly-L-lysine or protamine and the resulting conjugates could interact with DNA in a noncovalent bond to form a complex. Using pSV2-β-galactosidase as a reporter gene, it has been demonstrated that exogenous gene was transferred into bovine aortic arch-derived endothelial cells (ABAE) andhuman malignant melanoma cell lines (A375) in vitro. In vivo experiments, exogenous gene was transferred into tumor vascular endothelial cells and tumor cells of subcutaneously transplanted human colon cancer LOVO, human malignant melanoma A375 and human hepatoma graft in nude mice. This system could also target gene to intrahepatically transplanted human hepatoma injected via portal vein in nude mice. These results are correlated with theGene delivery system targeting VEGF receptors relevant receptors (flt-1, flk-1/KDR) expression on the targeted cells and tissues.LI JUN MIN JUN SONG HAN YI HUANG PEI KUN TIAN SHU MIN QU MIN YAO HUI QIU JIANG DA FANG WAN JING CHU LUO CHENG XIAO GU JIAN REN GU( National Labomtory for Oncogenes and Related Genes, Shanghai Cancer Institute, Shanghai 200032,China)(National Laboratory of 1999Cell Research1999,9,1:22
7Pneumoconiosis: current status and future prospects显示文摘Pneumoconiosis refers to a spectrum of pulmonary diseases caused by inhalation of mineral dust,usually as the result of certain occupations.The main pathological features include chronic pulmonary inflammation and progressive pulmonary fibrosis,which can eventually lead to death caused by respiratory and/or heart failure.Pneumoconiosis is widespread globally,seriously threatening global public health.Its high incidence and mortality lie in improper occupational protection,and in the lack of early diagnostic methods and effective treatments.This article reviews the epidemiology,safeguard procedures,diagnosis,and treatment of pneumoconiosis,and summarizes recent research advances and future research prospects.Xian-Mei Qi Ya Luo Mei-Yue Song Ying Liu Ting Shu Ying Liu Jun-Ling Pang Jing Wang Chen Wang 2021Chinese Medical Journal2021,,8:22

9Sirtuin 3 deficiency exacerbates diabetic cardiomyopathy via necroptosis enhancement and NLRP3 activation显示文摘Sirtuin 3(SIRT3)is a potential therapeutic target for cardiovascular,metabolic,and other aging-related diseases.In this study,we investigated the role of SIRT3 in diabetic cardiomyopathy(DCM).Mice were injected with streptozotocin(STZ,60 mg/kg,ip)to induce diabetes mellitus.Our proteomics analysis revealed that SIRT3 expression in the myocardium of diabetic mice was lower than that of control mice,as subsequently confirmed by real-time PCR and Western blotting.To explore the role of SIRT3 in DCM,SIRT3-knockout mice and 129S1/SvImJ wild-type mice were injected with STZ.We found that diabetic mice with SIRT3 deficiency exhibited aggravated cardiac dysfunction,increased lactate dehydrogenase(LDH)level in the serum,decreased adenosine triphosphate(ATP)level in the myocardium,exacerbated myocardial injury,and promoted myocardial reactive oxygen species(ROS)accumulation.Neonatal rat cardiomyocytes were transfected with SIRT3 siRNA,then exposed to high glucose(HG,25.5 mM).We found that downregulation of SIRT3 further increased LDH release,decreased ATP level,suppressed the mitochondrial membrane potential,and elevated oxidative stress in HG-treated cardiomyocytes.SIRT3 deficiency further raised expression of necroptosis-related proteins including receptor-interacting protein kinase 1(RIPK1),RIPK3,and cleaved caspase 3,and upregulated the expression of inflammation-related proteins including NLR family pyrin domain-containing protein 3(NLRP3),caspase 1 p20,and interleukin-1βboth in vitro and in vivo.Collectively,SIRT3 deficiency aggravated hyperglycemia-induced mitochondrial damage,increased ROS accumulation,promoted necroptosis,possibly activated the NLRP3 inflammasome,and ultimately exacerbated DCM in the mice.These results suggest that SIRT3 can be a molecular intervention target for the prevention and treatment of DCM.Shu Song Yue Ding Guo-liang Dai Yue Zhang Meng-ting Xu Jie-ru Shen Ting-ting Chen Yun Chen Guo-liang Meng 2021Acta Pharmacologica Sinica2021,42,2:14
10Grape Seed Proanthocyanidin Extract Alleviates Arsenic-induced Oxidative Reproductive Toxicity in Male Mice显示文摘Objective To determine the ability of grape seed proanthocyanidin extract(GSPE) in alleviating arsenic-induced reproductive toxicity. Methods Sixty male Kunming mice received the following treatments by gavage: normal saline solution(control); arsenic trioxide(ATO; 4 mg/kg); GSPE(400 mg/kg); ATO+GSPE(100 mg/kg); ATO+GSPE(200 mg/kg) and ATO+GSPE(400 mg/kg). Thereafter, the mice were sacrificed and weighed, and the testis was examined for pathological changes. Nuclear factor(erythroid-derived 2)-like 2(Nrf2), heme oxygenase 1(HO1), glutathione S-transferase(GST), NAD(P)H dehydrogenase, and quinone 1(NQO1) expression in the testis was detected by real-time PCR. Superoxide dismutase(SOD), glutathione(GSH), total antioxidative capability(T-AOC), malondialdehyde(MDA), 8-hydroxydeoxyguanosine(8-OHd G), and reproductive indexes were analyzed. Results ATO-treated mice showed a significantly decreased sperm count and testis somatic index and activity levels of SOD, GSH, and T-AOC than control group. Compared to the ATO-treated group, ATO +GSPE group showed recovery of the measured parameters. Mice treated with ATO+high-dose GSPE showed the highest level of m RNA expression of Nrf2, HO, NQO1, and GST. Conclusion GSPE alleviates oxidative stress damage in mouse testis by activating Nrf2 signaling, thus counteracting arsenic-induced reproductive toxicity.LI Shu Gang DING Yu Song NIU Qiang XU Shang Zhi PANG Li Juan MA Ru Lin JING Ming Xia FENG Gang Ling LIU Jia Ming GUO Shu Xia 2015Biomedical and Environmental Sciences2015,28,4:14
11The Predictive Value of Baseline HBs Ag Level and Early Response for HBs Ag Loss in Patients with HBe Ag-positive Chronic Hepatitis B during Pegylated Interferon Alpha-2a Treatment显示文摘Objective To explore the predictive value of baseline HBsAg level and early response for HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment. Methods A total of 121 patients with HBeAg-positive chronic hepatitis B who achieved HBsAg loss were enrolled; all patients were treated with PEG-IFNα-2a 180 μg/week. Serum HBV DNA and serological indicators(HBsAg, anti-HBs, HBeAg, and anti-HBe) were determined before and every 3 months during treatment. Results The median treatment time for HBsAg loss was 84 weeks(7-273 weeks), and 74.38%(90 cases) of the patients needed extended treatment(> 48 weeks). The correlation between baseline HBsAg levels and the treatment time of HBsAg loss was significant(B = 14.465, t = 2.342, P = 0.021). Baseline HBsAg levels together with the decline range of HBsAg at 24 weeks significantly correlated with the treatment time of HBsAg loss(B = 29.862, t = 4.890, P = 0.000 and B = 27.993, t = 27.993, P = 0.005). Conclusion Baseline HBsAg levels and extended therapy are critical steps toward HBsAg loss. Baseline HBsAg levels together with early response determined the treatment time of HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment.LI Ming Hui ZHANG Lu QU Xiao Jing LU Yao SHEN Ge LI Zhen Zhen WU Shu Ling LIU Ru Yu CHANG Min HU Lei Ping HUA Wen Hao SONG Shu Jing WAN Gang XIE Yao 2017Biomedical and Environmental Sciences2017,30,3:14
12Changes in count and function of splenic lymphocytes from patients with portal hypertension显示文摘AIM: To investigate changes in numbers and proliferative function of splenic lymphocytes in patients with hypersplenism due to portal hypertension (PH), to provide evidence for further study of immune status of the spleen during PH. METHODS: Twelve spleens from patients with hypersplenism due to PH served as the PH group, and four spleens from cases of traumatic spleen rupture were regarded as the control group. After weighing the spleen, lymphocytes were separated and counted using a cell counting plate to calculate the lymphocyte count per gram of spleen tissue (relative quantity) and total lymphocyte count in whole spleen (absolute quantity). The immunohistochemical SP method was used to observe the density and distribution of lymphocytes in the spleen. The MTT method was used to observe changes in lymphocyte proliferative function. RESULTS: As compared to the control group, the splenic lymphocytes in the PH group showed that: (1) There was no difference in distribution but a significant decreasein density; (2) the number of lymphocytes per gram of spleen (relative quantity) decreased significantly (0.822 ± 0.157) × 108 vs (1.174 ± 0.254) × 108, P < 0.01]; (3) with the significant increase in the weight of the PH spleen (832.6 ± 278.2 g vs 211.7 ± 85.6 g, P < 0.01), the total quantity of lymphocytes (absolute quantity) increased significantly (0.685 ± 0.072) × 1011 vs (0.366 ± 0.057) × 1011, P < 0.01]; and (4) the proliferative function of lymphocytes was enhanced: T lymphocytes, (0.022 ± 0.005 vs 0.015 ± 0.003, P < 0.05), and B lymphocytes (0.034 ± 0.006 vs 0.023 ± 0.001, P < 0.01). CONCLUSION: Although lymphocyte density in the spleen decreased in patients with PH, the total quantity of lymphocytes increased because spleen weight increased greatly, along with the proliferating function. With respect to changes in lymphocytes, PH spleens may still have immune function, although it may be disordered. However, complete evaluation of the immune function of the spleen in PH requires more research.Zong-Fang Li Shu Zhang Gao-Bo Lv Ying Huang Wei Zhang Song Ren Jun Yang Shuang-Suo Dang 2008World Journal of Gastroenterology2008,14,15:13
13Research on Link Quality Estimation Mechanism for Wireless Sensor Networks Based on Support Vector Machine显示文摘In the application of Wireless sensor networks(WSNs),effective estimation for link quality is a basic issue in guarantying reliable data transmission and upper network protocol performance.A link quality estimation mechanism is proposed,which is based on Support vector machine(SVM) with multi-class classification.Under the analysis of the wireless link characteristics,two physical parameters of communication,Receive signal strength indicator(RSSI) and Link quality indicator(LQI),are chosen as estimation parameters.The link quality is divided into five levels according to Packet reception rate(PRR).A link quality estimation model based on SVM with decision tree is established.The model is built on kernel functions of radial basis and polynomial respectively,in which RSSI,LQI are the input parameters.The experimental results show that the model is reasonable.Compared with the recent published link quality estimation models,our model can estimate the current link quality accurately with a relative small number of probe packets,so that it costs less energy consumption than the one caused by sending a large number of probe packets.So this model which is high efficiency and energy saving can prolong the network life.SHU Jian LIU Song LIU Linlan ZHAN Liqin HU Gang 2017Chinese Journal of Electronics2017,26,2:12

15Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
16The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11

19Comparison and optimization of the method for Cry1Ac protoxin preparation in HD73 strain显示文摘Bacillus thuringiensis is one of the most widely used bioinsecticides, and cry gene is the major insecticidal gene.Because Cry1 Ac protein shows strong toxicity against many lepidopteran species, it has been applied widely in spraying products and transgenic Bt-crops.The preparation of Cry protoxin is the first step in the very important processes of understanding the insecticidal mechanism, resistance screening, and biosafety assessments.The media for crystal production and the method for Cry protoxin preparation were varied, however, it was not clear which was better for preparing a larger amount of Cry protoxin.In this paper, three media for crystal production and the method for Cry1 Ac protoxin preparation from HD73 strain were compared to find an efficacious way to prepare a large number of Cry1 Ac protoxin.The results showed that the 1/2 LB(Luria-Bertani) medium was the ideal medium for crystal production, because the total yield of Cry1 Ac protoxin in 300 m L 1/2 LB medium was(112.38±5.64) mg, the highest one among three media; the repeated crystal solubilization method was better for the preparation of the Cry protoxin comparing with the continuous crystal solubilization method.It will be a reference for other Cry protoxin preparation, especially for larger number.ZHOU Zi-shan YANG Su-juan SHU Chang-long SONG Fu-ping ZHOU Xue-ping ZHANG Jie 2015Journal of Integrative Agriculture2015,14,8:10
20A Five-year Surveillance of Carbapenemase-producing Klebsiella pneumoniae in a Pediatric Hospital in China Reveals Increased Predominance of NDM-1显示文摘Objective To characterize carbapenem(CPM)-non-susceptible Klebsiel a pneumoniae(K. pneumoniae) and carbape-nemase produced by these strains isolated from Beijing Children's Hospital based on a five-year surveillance. Methods The Minimal Inhibition Concentration values for 15 antibiotics were assessed using the Phonix100 compact system. PCR amplification and DNA sequencing were used to detect genes encoding carbapenemases. WHONET 5.6 was finally used for resistance analysis. Results In total, 179 strains of CPM-non-susceptible K. pneumoniae were isolated from January, 2010 to December, 2014. The rates of non-susceptible to imipenem and meropenem were 95.0% and 95.6%, respectively. In the 179 strains, 95(53.1%) strains carried the blaIMP gene, and IMP-4 and IMP-8 were detected in 92(96.8%) and 3(3.2%) IMP-producing isolates, respectively. 65(36.3%) strains carried the blaNDM-1 gene. 6(3.4%) strains carried the blaKPC gene, and KPC-2 were detected in 6 KPC-producing isolates. In addition, New Delhi-Metallo-1(NDM-1) producing isolates increased from 7.1% to 63.0% in five years and IMP-4 producing isolates decreased from 75.0% to 28.3%. Conclusion High frequencies of multiple resistances to antibiotics were observed in the CPM-non-susceptible K. pneumoniae strains isolated from Beijing Children's Hospital. The production of IMP-4 and NDM-1 metallo-β-lactamases appears to be an important mechanism for CPM-nonsusceptible in K. pneumoniae.DONG Fang LU Jie WANG Yan SHI Jin ZHEN Jing Hui CHU Ping ZHEN Yang HAN Shu Jing GUO Yong Li SONG Wen Qi 2017Biomedical and Environmental Sciences2017,30,8:10
