5Analysis of the Fungal Community in Apple Replanted Soil Around Bohai Gulf显示文摘Apple replant disease(ARD) is a frequently occurring plant disease in replanted orchards around Bohai Gulf, which causes growth inhibition and even death of plants. The aim of this study was to investigate the etiology of ARD around Bohai Gulf. In this study, the primary growth inhibition of apple seedlings was evaluated in ten replanted soils, sampled around Bohai Gulf. A fungal clone library was used to identify changes in the structure and composition of the soil fungal community. The results revealed that the Simpson diversity indices of Laizhou and Pulandian orchards were higher than others, presenting severe ARD. Ascomycota dominated around Bohai Gulf at the phyla level. Fusarium and Saccharomyces were abundant in all replanted soils. In addition, correlations between the relative abundance of fungal genera in soils and the severity of ARD were analyzed. The results showed that Fusarium was correlated positively with the severity of ARD, but Mortierella was negatively correlated. Furthermore, the quantitative PCR of Fusarium oxysporum, which was regarded as a factor of ARD, was performed. Overall, this study demonstrated that ARD was strongly associated with an unbalanced microbial ecosystem with more pathogenic fungi, while Fusarium in the apple replanted soil was the key factor for ARD around Bohai Gulf.WANG Gongshuai YIN Chengmiao PAN Fengbing WANG Xiaobao XIANG Li WANG Yanfang WANG Jinzheng TIAN Changping CHEN Jie MAO Zhiquan 2018Horticultural Plant Journal2018,4,5:21
6Effects of Short-Term Forest Bathing on Human Health in a Broad-Leaved Evergreen Forest in Zhejiang Province,China显示文摘Objective To investigate the effects of short-term forest bathing on human health.Methods Twenty healthy male university students participated as subjects and were randomly divided into two groups of 10.One group was sent on a two-night trip to a broad-leaved evergreen forest,and the other was sent to a city area.Serum cytokine levels reflecting inflammatory and stress response,indicators reflecting oxidative stress,the distribution of leukocyte subsets,and plasma endothelin-1 (ET-1) concentrations were measured before and after the experiment to evaluate the positive health effects of forest environments.A profile of mood states (POMS) evaluation was used to assess changes in mood states.Results No significant differences in the baseline values of the indicators were observed between the two groups before the experiment.Subjects exposed to the forest environment showed reduced oxidative stress and pro-inflammatory level,as evidenced by decreased malondialdehyde,interleukin-6,and tumor necrosis factor α levels compared with the urban group.Serum cortisol levels were also lower than in the urban group.Notably,the concentration of plasma ET-1 was much lower in subjects exposed to the forest environment.The POMS evaluation showed that after exposure to the forest environment,subjects had lower scores in the negative subscales,and the score for vigor was increased.Conclusion Forest bathing is beneficial to human health,perhaps through preventive effects related to several pathological factors.MAO Gen Xiang LAN Xiao Guang CAO Yong Bao CHEN Zhuo Mei HE Zhi Huat LV Yuan Dong WANG Ya Zhen HU Xi Lian WANG Guo Fu YAN Jing 2012Biomedical and Environmental Sciences2012,25,3:20

11Amplitude-Integrated Electroencephalography Predicts Outcome in Patients with Coma After Acute Brain Injury显示文摘Prognostication of coma patients after brain injury is important, yet challenging. In this study, we evaluated the predictive value of amplitude-integrated electroencephalography(a EEG) for neurological outcomes in coma patients. From January 2013 to January 2016, 128 coma patients after acute brain injury were prospectively enrolled and monitored with a EEG. The 6-month neurological outcome was evaluated using the Cerebral Performance Category Scale. a EEG monitoring commenced at a median of 7.5 days after coma onset. Continuous normal voltage predicted a good 6-month neurological outcome with a sensitivity of 93.6% and specificity of 85.2%. In contrast, continuous extremely low voltage, burst-suppression, or a flat tracing was correlated with poor 6-month neurological outcome with a sensitivity of 76.5% and specificity of 100%. In conclusion, a EEG is a promising predictor of 6-month neurological outcome for coma patients after acute brain injury.Wendong You Qilin Tang Xiang Wu Junfeng Feng Qing Mao Guoyi Gao Jiyao Jiang 2018Neuroscience Bulletin2018,34,4:15
12Myocardial infarction secondary prevention study (MISPS)显示文摘Background Traditional Chinese medicine (TCM), especially herbal medicine, has been widely used in China and now is also being increasingly used in other countries for the treatment of cardiovascular diseases. Although many studies have demonstrated that certain Chinese herbal products are effective and safe for the treatment of cardiovascular diseases, most of these lack sufficient quality. Therefore, large randomized clinical trials and further scientific research to determine its safety, effectiveness are necessary.QiShen YiQi Dripping Pills (QSYQDP) is a herbal preparation clinically used in the treatment and prevention of coronary artery disease. Preliminary observations have shown its safety and effectiveness. Methods/Design This randomized, controlled trial will recruit 3600 patients with a history of myocardial infarction. Patients will be randomized into two groups by a Centr-Randomized System. One group receives QSYQDP, the other group receive aspirin. This trial protocol will describe eligibility criteria, detailed information on the treatment definition, blinding, endpoints, statistical methods, sample size determination, data management, legal aspects, and the current status of the trial. Discussion This trial is one of the first randomized, controlled clinical trial to evaluate the efficacy and safety of traditional Chinese herbal medicine in the treatment and secondary prevention of coronary artery disease. The results of this study should help to define the role of TCM in modern medical care, as well as to provide the management strategy for CAD patients in China and other countries.Hongcai SHANG Guohua DAI Junhua HANG Yaozu XIANG Yang WANG Junping ZHANG Wuxun DU Jingyuan MAO Chen YAO Weiliang WENG Tiancai WEN Boli ZHANG 2006Journal of Geriatric Cardiology2006,3,2:14

16Modulation of TGFβ_2 and dopamine by PKC in retinal Müller cells of guinea pig myopic eye显示文摘AIM: To investigate the effect of protein kinase C (PKC) on transforming growth factor-β2 (TGFβ2) and dopamine in retinal Müller cells of guinea pig myopic eye. METHODS: Myopia was induced by translucent goggles in guinea pig, whose retinal Müller cells were cultured using the enzyme-digesting method. Retinal Müller cells were divided into 5 groups: normal control, myopia, myopia plus GF109203X, myopia plus PMA, myopia plus DMSO. PKC activities were detected by the non-radioactive methods. TGFβ2 and tyrosine hydroxylase (TH) proteins were analyzed by Western Blotting in retinal Müller cells. Dopamine was determined by the high-performance liquid chromatography- electrochemical detection in suspensions. RESULTS: After 14 days deprived, the occluded eyes became myopic with ocular axle elongating. Müller cells of guinea pigs were obtained using enzyme digestion. Compared with normal control group, the increase in PKC activity and the up-regulation in TGFβ2 expression were found in retinal Müller cells of myopic eyes, with the decrease of TH and dopamine content (P <0.05). After PKC activated by PMA, TGFβ2 and TH content were up-regulated with the increase of dopamine content (P <0.05). While the PKC activities was inhibited by GF109203X, proteins of TGFβ2 and TH were down-regulated in the myopic eyes, with the decrease of dopamine content (P <0.05). CONCLUSION: TGFβ2 and dopamine are modulated by PKC in Müller cells of the myopic eyes in guinea pig.Jun-Feng Mao, Shuang-Zhen Liu, Wen-Juan Qin, Qian Xiang Department of Ophthalmology, Xiangya Hospital of Central South University, Changsha 410008, Hunan Province, China 2011International Journal of Ophthalmology(English edition)2011,4,4:10
17Controlled synthesis of single cobalt atom catalysts via a facile one-pot pyrolysis for efficient oxygen reduction and hydrogen evolution reactions显示文摘Metal-nitrogen doped carbon catalysts(M-N/C) with abundantly accessible M-Nxsites, particularly single metal atom M-N/C(SAM-N/C), have been developed as a substitute for expensive Pt-based catalysts.These catalysts are used to increase the efficiency of otherwise sluggish oxygen reduction reactions(ORR) and hydrogen evolution reactions(HER). However, although the agglomerated metal nanoparticles are usually easy to form, they are very difficult to remove due to the protective surface-coating carbon layers, a factor that significantly hampers SAM-N/C fabrication. Herein, we report a one-step pyrolysis approach to successfully fabricate single cobalt atom Co-N/C(SACo-N/C) by using a Co2+-SCN-coordination compound as the metal precursor. Thanks to the decomposition of Co2+-SCN-compound at lower temperature than that of carbon layer deposition, Co-rich particles grow up to larger ones before carbon layers formation. Even though encapsulated by the carbon layers, it is difficult for the large Co-rich particle to be completely sealed. And thus, it makes the Co atoms possible to escape from incomplete carbon layer, to coordinate with nitrogen atoms, and to form SACo-N/C catalysts. This SACo-N/C exhibits excellent performances for both ORR(half-wave potential of 0.878 V) and HER(overpotential at 10 mA/cm2 of178 m V), and is thus a potential replacement for Pt-based catalysts. When SACo-N/C is integrated into a Zn-O2 battery, battery with high open-circuit voltage(1.536 V) has high peak power density(266 mW/cm2)and large gravimetric energy density(755 mA h/gZn) at current densities of 100 mA/cm2. Thus, we believe that this strategy may offer a new direction for the effective generation of SAM-N/C catalysts.Yao Wang Linhui Chen Zhanxin Mao Lishan Peng Rui Xiang Xianyi Tang Jianghai Deng Zidong Wei Qiang Liao 2019Science Bulletin2019,64,15:10
18First dark matter search results from the PandaX-Ⅰ experiment显示文摘We report on the first dark-matter(DM)search results from PandaX-I,a low threshold dual-phase xenon experiment operating at the China JinPing Underground Laboratory.In the 37-kg liquid xenon target with 17.4 live-days of exposure,no DM particle candidate event was found.This result sets a stringent limit for low-mass DM particles and disfavors the interpretation of previously-reported positive experimental results.The minimum upper limit,3.7×10-44cm2,for the spin-independent isoscalar DM-particle-nucleon scattering cross section is obtained at a DM-particle mass of 49 GeV/c2at 90%confidence level.XIAO MengJiao XIAO Xiang ZHAO Li CAO XiGuang CHEN Xun CHEN YunHua CUI XiangYi FANG DeQing FU ChangBo GIBONI Karl L.
