| 1 | Isolated Cases of Plague--Inner Mongolia-Beijing, 2019显示文摘What is already known about this topic?Plague is an acute infectious disease caused by Yersinia pestis(Y.pestis)and is primarily transmitted by rodents.Human can be infected by bites of bacterium-bearing fleas or direct contact with diseased or dead plagueinfected animals.In 2004,the last human plague case was reported in Inner Mongolia Autonomous Region due to skinning a dead hare.What is added by this report?This is the first case of pneumonic plague imported into a major city since the founding of the People's Republic of China.Two primary pneumonic plague cases(Patients A and B)found in residents of Inner Mongolia were confirmed in Beijing on November 12,2019.Another case(Patient C)of Y.pestis was identified as bubonic plague on November 14.Patient A most likely became infected from aerosol exposure to infective droplets while digging on his farm,located in an Meriones unguiculatus(M.unguiculatus)natural plague focus.Patient B became infected from contact with Patient A(her husband).Patient C became infected after skinning a dead hare.There was no epidemiological relationship between the Patient A/B and Patient C.What are the implications for public health practice?When epizootic plague is detected,local health-care providers and the public should be alerted about any possible risks.Public education efforts should focus on promoting personal protection measures. | Yumeng Wang Lei Zhou Mengguang Fan Quanyi Wang Jianyun Li Qun Li Zijian Feng George FGao Cheng Xu Lijuan Chen Wei Li Yanping Zhang | 2019 | China CDC weekly2019，1，1： | 13 |
| 2 | The effects of air temperature and precipitation on the net primary productivity in China during the early 21st century显示文摘Research on how terrestrial ecosystems respond to climate change can reveal the complex interactions between vegetation and climate,net primary productivity (NPP),an important vegetation parameter and ecological indicator,fluctuates within any given ecological environment or regional carbon budget.In this study, spatial interpolation was used to generate a spatial dataset, with 1-km spatial resolution,with meteorological data from 736 observation stations across China.An improved CASA model was used to simulate NPP over the period of 2001-2013 by taking into account land-cover change in every year during the same period.We propose the grid- based spatial patterns and dynamics of annual NPP,annual average temperature,and annual total precipitation based on the model.We also used the model to demonstrate the spatial correlation between NPP,temperature,and pre- cipitation in the study area with special focus on the impact of climate change in the early 21st century.Results showed that the spatial pattern of NPP over all of China is characterized by higher values in the southeast and lower values in the northwest.The spatial pattern of temperature indicates substantial latitudinal differences across the country,and the spatial pattem of precipitation shows a ribbon of decline from the southeast coast to the northwest inland.Most areas show an upward trend in NPP. Temperatures appear to decrease across the country during the global warming hiatus (1998-2008),and are accom- panied by an increase in precipitation over most regions.The correlation between NPP and annual average temperature is weak.Alternatively,NPP and annual total precipitation are positively correlated in northern and central China at a coefficient above 0.64(p <0.01)yet negatively correlated in the eastem parts of the Qinghai- Tibet Plateau and Sichuan Basin.Results can provide useful information for improving parameters for calibra- tion of the terrestrial ecosystem process model. | Qianfeng WANG Jingyu ZENG Song LENG Bingxiong FAN Jia TANG Cong JIANGs Yi HUANG Qing ZHANG Yanping QU Wnlin WANG Wei SHUI | 2018 | Frontiers of Earth Science2018，12，4： | 6 |

| 4 | A novel method for evaluating the dynamic biocompatibility of degradable biomaterials based on real-time cell analysis显示文摘Degradable biomaterials have emerged as a promising type of medical materials because of their unique advantages of biocompatibility,biodegradability and biosafety.Owing to their bioabsorbable and biocompatible properties,magnesium-based biomaterials are considered as ideal degradable medical implants.However,the rapid corrosion of magnesium-based materials not only limits their clinical application but also necessitates a more specific biological evaluation system and biosafety standard.In this study,extracts of pure Mg and its calcium alloy were prepared using different media based on ISO 10993:12;the Mg^2+ concentration and osmolality of each extract were measured.The biocompatibility was investigated using the MTT assay and xCELLigence real-time cell analysis(RTCA).Cytotoxicity tests were conducted with L929,MG-63 and human umbilical vein endothelial cell lines.The results of the RTCA highly matched with those of the MTT assay and revealed the different dynamic modes of the cytotoxic process,which are related to the differences in the tested cell lines,Mg-based materials and dilution rates of extracts.This study provides an insight on the biocompatibility of biodegradable materials from the perspective of cytotoxic dynamics and suggests the applicability of RTCA for the cytotoxic evaluation of degradable biomaterials. | Xiaoxiao Gai Chenghu Liu Guowei Wang Yang Qin Chunguang Fan Jia Liu Yanping Shi | 2020 | Regenerative Biomaterials2020，7，3： | 3 |
| 5 | Phenotypic identification of peanut germplasm for resistance to southern stem rot显示文摘Southern stem rot,caused by Sclerotium rolfsii Sacc.,is a destructive soil fungal disease of peanut in China and other countries.To evaluate resistant germplasm,a total of 256 peanut accessions were investigated on their resistance to southern stem rot in 3 environments by artificial inoculation.Variance analysis indicated that disease index was significantly influenced by environment,genotype and genotypeenvironment interactions.Peanut accessions of var.vulgaris type exhibited higher resistance to southern stem rot.Disease index was significantly negatively correlated with linoleic acid content,while positively correlated with oleic acid content.Six resistant accessions were identified,including Hua 28,Shandongzai,ICG 6326,Quanhua 7,Quanhua 9 and Guihua 836,with their disease indexes under 40 and mortality were less than 30%in the three environments.The identified resistant accessions showed the great potential to be applied in resistant peanut breeding,and would be good genetic resources for enhancing the resistance to southern stem rot. | Pengmin Fan Wanduo Song Yanping Kang Liyun Wan Yong Lei Dongxin Huai Yuning Chen Xin Wang Huifang Jiang Liying Yan Boshou Liao | 2020 | Oil Crop Science2020，5，4： | 3 |
| 6 | Co-CoO_x supported onto TiO_(2) coated with carbon as a catalyst for efficient and stable hydrogen generation from ammonia borane显示文摘Ammonia borane(AB) can be catalytically hydrolyzed to provide hydrogen at room temperature due to its high potentaial for hydrogen storage. Non-precious metal heterogeneous catalysts have broad application in the field of energy catalysis. In this article, catalysts precursor is obtained from Co-Ti-resorcinol-formaldehyde resin by sol–gel method. Co/TiO_(2)@N-C(CTC) catalyst is prepared by calcining the precursor under high temperature conditions in nitrogen atmosphere. Co-CoO_x/TiO_(2)@N-C(COTC) is generated by the controllable oxidation reaction of CTC. The catalyst can effectively promote the release of hydrogen during the hydrolytic dehydrogenation of AB. High hydrogen generation at a specific rate of 5905 m L min^(-1) g_(Co)^(-1) is achieved at room temperature. The catalyst retains its 85% initial catalytic activity even for its fifth time use in AB hydrolysis. The synergistic effect among Co, Co_(3)O_(4) and TiO_(2) promotes the rate limiting step with dissociation and activation of water molecules by reducing its activation energy. The applied method in this study promotes the development of non-precious metals in catalysis for utilization in clean energy sources. | Guang Yang Shuyan Guan Sehrish Mehdi Yanping Fan Baozhong Liu Baojun Li | 2021 | Green Energy & Environment2021，6，2： | 2 |

| 9 | YTHDF2 is essential for spermatogenesis and fertility by mediating a wave of transcriptional transition in spermatogenic cells显示文摘The dynamic and reversible regulation roles of m^(6)A modification and the characterization of m^(6)A readers have provided new insights into spermatogenesis at the post-transcriptional level.YTHDF2,as an m^(6)A reader,has been reported to mediate the m^(6)A-containing transcript decay during the mouse oocyte maturation,embryonic stem cell differentiation,neural development,and zebrafish maternal-to-zygotic transition.However,the roles of YTHDF2 in mammalian spermatogenesis are uncertain.Here,we generated germ cell-specific Ythdf2 mutants(Ythdf2-vKO)at a C57BL/6J background and demonstrated that YTHDF2 is essential for mouse spermatogenesis and fertility.Ythdf2-vKO provides oligoasthenoteratozoospermia phenotype with increased apoptosis in germ cells.High-throughput RNA-seq analysis showed that a group of mRNAs is upregulated in Ythdf2-vKO mouse testis;further analysis and MeRIP-qPCR data showed that most of the upregulated genes in Ythdf2-vKO mouse testis are modified with m^(6)A and are YTHDF2 candidate binding genes.Interestingly,RNA-seq analysis combined with our previous single-cell transcriptomics data of mouse spermatogenesis pointed out the failure of a wave of transcript transition during the spermatogenesis of Ythdf2-vKO mice,which was confirmed by gene expression analysis using qPCR of diplotene spermatocytes and round spermatids obtained through fluorescence-activated cell sorting.Our study demonstrates the fundamental role of YTHDF2 during mouse spermatogenesis and provides a potential candidate for the diagnosis of male infertility with the oligoasthenoteratozoospermia syndrome. | Xinxi Zhao Zhen Lin Yong Fan Wenzhi Li Yujie Zhang Fei Li Tong Hong Hua Feng Minghan Tong Ningling Wang Yanping Kuang Qifeng Lyu | 2021 | Acta Biochimica et Biophysica Sinica2021，53，12： | 2 |

| 14 | Vasorelaxant effect of osthole on isolated thoracic aortic rings in rats显示文摘OBJECTIVE: To investigate the effect of osthole on isolated thoracic aortic rings, and to determine the potential mechanism of action.METHODS: Thoracic aortas were isolated from Wistar rats, and were suspended in tissue organ chambers for vascular tension measurement. The effect of cumulative osthole(10-9, 10-8, 10-7, 10-6, and 10-5 mol/L) on endothelium-intact and endothelium-denuded thoracic aortic rings pre-contracted with phenylephrine(PE, 10-6 mol/L) or KCl(6 × 10-2 mol/L) was recorded. Histomorphological changes of thoracic aorta were analyzed by hematoxylin-eosin. The effects of different osthole concentrations on endothelium-intact aortic rings, which were pre-inhibited with the non-selective nitric oxide synthase inhibitor L-Arg(NO2)-OMe·HCl(3 × 10-4 mol/L), endothelium-derived nitric oxide synthase inhibitor Nω-nitro-L-arginine(3 × 10-4 mol/L), guanylate cyclase inhibitor 1 H-[1,2,4] oxadiazolo [4,3-α]quinoxaline-1-one(10-5 mol/L), cyclooxygenase inhibitor indometacin(10-5 mol/L), and the Ca2+-activated potassium channel inhibitor tetraethylammonium nitrate(10-5 mol/L), and then contracted with PE, were examined. Aortic rings incubated with osthole(10-5 mol/L), phentolamine(10-5 mol/L), or verapamil(10-5 mol/L) in Ca2+-free Krebs-Henseleit solution(KHS) were stimulated with PE or KCl.RESULTS: There was a dose-dependent increase in vasorelaxation of isolated thoracic aortic rings(both with and without endothelium) with increasing osthole concentration. Hematoxylin-eosin staining showed that osthole significantly improved thoracic aorta ring morphology. Compared with the control group, there were also significant differences after incubation with L-Arg(NO2)-OMe ω-nitro-L-arginine, and 1 H-[1,2,4] oxadiazo·lo HCl,N [4,3-α] quinoxaline-1-one(P < 0.05 for all). The relaxation rate of the rings in the osthole group incubated with indometacin and tetraethylammonium nitrate were similar to controls. In Ca2+-free KHS, the PE-induced contraction was similar between the osthole(4.37% ± 0.41%) and control(4.21% ± 1.33%)groups. However, after cumulative CaCl2(0.5, 1, 1.5,2, 2.5, and 3 mmol/L), the Ca2+-induced contraction was significantly inhibited in the osthole and phentolamine groups compared with controls(P < 0.05).After cumulative CaCl2 was added to Ca2+-free KHS(high K+ concentration), the contraction rate was significantly higher than both of the control and the osthole groups(P < 0.05). The contraction rate in the osthole group was higher than the verapamil group(P < 0.05).CONCLUSION: Osthole has a vasorelaxant effect on isolated rat thoracic aortic rings, via inhibition of both receptor-operated and voltage-dependent Ca2+channels in arterial smooth muscle, leading to decreased Ca2+ influx, and via inhibition of nitric oxide release on arterial endothelial cells. | Huang Ying Kong Liting Wang Yanping Sun Mingjie Cui Haifeng Zhai Huaqiang LüCheng Fan Danping | 2019 | Journal of Traditional Chinese Medicine2019，39，4： | 1 |
