1Chinese Multidisciplinary Expert Consensus on the Diagnosis and Treatment of Hyperuricemia and Related Diseases显示文摘Zou, He-Jian Wu, Hu-Sheng Zhou, Jing-Guo Zeng, Xue-Jun Dai, Lie Wu, Hua-Xiang Zhu, Xiao-Xia Mei, Chang-Lin Hao, Chuan-Ming Chen, Nan Liu, Bi-Cheng Chen, Jiang-Hua Yang, Li Nie, Jing Yu, Chen Peng, Ai Yu, Sheng-Qiang Li, Lin Ge, Jun-Bo Huo, Yong Zhang, Shu-Yang Chen, Yun-Dai Dong, Yu-Gang Liang, Chun Dai, Yu-Xiang Gao, Xin Li, Chang-Gui Zhao, Jia-Jun Chen, Hai-Bing Cheng, Zhi-Feng Lin, Huan-Dong Guan, Yang-Tai Wang, Kai Luo, Ben-Yan Dai, Ruo-Lian Jiang, Quan Xue, Luan Liang, Chao-Chao Chen, Ming Fan, Song 2017Chinese Medical Journal2017,,20:30
2Hydrogen peroxide-induced changes in intracellular pH of guard cells precede stomatal closure显示文摘Epidermal bioassay demonstrated that benzylamine, a membrane-permeable weak base, can mimick hydrogen peroxide (H2O2) to induce stomatal closure, and butyric acid, a membrane-permeable weak acid, can partly abolish the H2O2-induced stomatal closure. Confocal pH mapping with the probe 5-(and-6)- carboxy seminaphthorhodafluor- 1 - acetoxymethylester (SNARF-1-AM) revealed that H2O2 leads to rapid changes in cytoplasmic and vacuolar pH in guard cells of Viola faba L, i. e. alkalinization of cytoplasmic areas occur red in parallel with a decrease of the vacuolar pH, and that butyric acid pretreatment can abolish alkalinization of cytoplasmic areas and acidification of vacuolar areas of guard cells challenged with H2O2. These results imply that the alkalinization of cytoplasm via efflux of cytosol protons into the vacuole in guard cells challenged with H2O2 is important at an early stage in the signal cascade leading to stomatal closure.ZHANG XIAO, FA CAI DONG, JUN FENG GAO, CHUN PENG SONG (Department of Biology, Henan University, Kaifeng 475001, China) (College of Life Sciences, Northwest Sci-Tech University of Agriculture and Forestry, Yangling 712100, China) 2001Cell Research2001,11,1:24
3Calcium channel blockers reduce severe fever with thrombocytopenia syndrome virus (SFTSV) related fatality显示文摘Severe fever with thrombocytopenia syndrome (SFTS),an emerging tick-borne infectious disease caused by a novel phlebovirus (SFTS virus, SFTSV), was listed among the top 10 priority infectious diseases by the World Health Organization due to its high fatality of 12%-50% and possibility of pandemic transmission. Currently, effective anti-SFTSV intervention remains unavailable. Here, by screening a library of FDA-approved drugs, we found that benidipine hydrochloride, a calcium channel blocker (CCB), inhibited SFTSV replication in vitro. Benidipine hydrochloride was revealed to inhibit virus infection through impairing virus internalization and genome replication. Further experiments showed that a broad panel of CCBs, including nifedipine, inhibited SFTSV infection. The anti-SFTSV effect of these two CCBs was further an a lyzed in a humanized mouse model in which CCB treatment resulted in reduced viral load and decreased fatality rate. Importantly, by performing a retrospective clinical investigation on a large cohort of 2087 SFTS patients, we revealed that nifedipine administration enhaneed virus clearance, improved clinical recovery, and remarkably reduced the case fatality rate by >5-fold. These findings are highly valuable for developing potential host-oriented therapeutics for SFTS and other lethal acute viral infections known to be inhibited by CCBs in vitro.Hao Li Lei-Ke Zhang Shu-Fen Li Shao-Fei Zhang Wei-Wei Wan Yu-Lan Zhang Qi-Lin Xin Ke Dai Yuan-Yuan Hu Zhi-Bo Wang Xiang-Tao Zhu Yu-Jie Fang Ning Cui Pan-He Zhang Chun Yuan Qing-Bin Lu Jie-Ying Bai Fei Deng Geng-Fu Xiao Wei Liu Ke Peng 2019Cell Research2019,29,9:15

6Optimal proportion of wind and PV capacity in provincial power systems based on bilevel optimization algorithm under low-carbon economy显示文摘In order to boost contributions of power systems to a low-carbon economy,the installed capacity of renewable power generation,such as wind and photovoltaic(PV)power generation should be well planned.A bilevel formulation is presented to optimize the proportion of wind and PV capacity in provincial power systems,in which,carbon emissions of generator units and features of renewable resources are taken into account.In the lowerlevel formulation,a time-sequence production simulation(TSPS)model that is suitable for actual power system has been adopted.In order to maximize benefits of energy conservation and emissions reduction resulting from renewable power generation,the commercial software called General Algebraic Modeling System(GAMS)is employed to optimize the annual operation of the power system.In the upper-level formulation,the optimal pattern search(OPS)algorithm is utilized to optimize the proportion of wind and PV capacity.The objective of the upper-level formulation is to maximize benefits of energy conservation and carbon emissions reductions optimized in the lowerlevel problem.Simulation results in practical provincial power systems validate the proposed model and corresponding solving algorithms.The optimization results can provide support to policy makers to make the polices related to renewable energy.Yue YUAN Yang CAO Xinsong ZHANG Chun LIU Yuehui HUANG Peng LI Kejun QIAN 2015Journal of Modern Power Systems and Clean Energy2015,3,1:11

8Mass transfer model,preparation and applications of zeolite membranes for pervaporation dehydration:A review显示文摘Pervaporation(including vapor permeation) is a kind of new membrane separation technology, possessing the advantages of high efficiency, energy saving and convenient operation. It has promising application in the separation and purification of organic solvents. Dehydration is an important step in the production and recovery of organic solvents. Zeolite membranes have attracted wide attention for pervaporation dehydration due to their high separation performance and good thermal/chemical stability. So far, zeolite membranes have been preliminarily industrialized for dehydration of organic solvents. This paper reviews the recent development of zeolite membranes for pervaporation dehydration, including mass transfer models, preparation and applications of zeolite membranes. The review also discusses the current industrial applications of zeolite membranes and their future development in pervaporation.Chun Zhang Li Peng Ji Jiang Xuehong Gu 2017Chinese Journal of Chemical Engineering2017,25,11:11
9Typical atmospheric haze during crop harvest season in northeastern China:A case in the Changchun region显示文摘This study presents the mass concentrations of PM_(2.5),O_3,SO_2 and NOxat one urban,one suburban and two rural locations in the Changchun region from September 25 to October 272013. Major chemical components of PM_(2.5)at the four sites were daily sampled and analyzed. Most of daily concentrations of SO_2(7–82 μg/m^3),O_3(27–171 μg/m^3) and NOx(14–213 μg/m^3) were below the limits of the National Ambient Air Quality Standard(NAAQS)in China. However,PM_(2.5)concentrations(143–168 μg/m^3) were 2-fold higher than NAAQS.Higher PM_(2.5)concentrations(~ 150 μg/m^3) were measured during the pre-harvest and harvest at the urban site,while PM_(2.5)concentrations significantly increased from 250 to400 μg m^(-3) at suburban and rural sites with widespread biomass burning. At all sites,PM_(2.5)components were dominated by organic carbon(OC) and followed by soluble component sulfate(SO_4^(2-)),ammonium(NH_4^+) and nitrate(NO_3^-). Compared with rural sites,urban site had a higher mineral contribution and lower potassium(K^+and K) contribution to PM_(2.5).Severe atmospheric haze events that occurred from October 21 to 23 were attributed to strong source emissions(e.g.,biomass burning) and unfavorable air diffusion conditions.Furthermore,coal burning originating from winter heating supply beginning on October 18 increased the atmospheric pollutant emissions. For entire crop harvest period,the Positive Matrix Factorization(PMF) analysis indicated five important emission contributors in the Changchun region,as follows: secondary aerosol(39%),biomass burning(20%),supply heating(18%),soil/road dust(14%) and traffic(9%).Wei Wei Chen Daniel Q.Tong Mo Dan Shi Chun Zhang Xue Lei Zhang Yue Peng Pan 2017Journal of Environmental Sciences2017,29,4:10
10High risk populations and HIV-1 infection in China显示文摘China is currently experiencing one of the most rapidly expanding HIV epidemics in the world. Although the overall prevalence rate is still low, with a population of 1.3 billion, high-risk factors which have contributed to the HIV/AIDS epidemics worldwide continue to prevail in China, including a high rate of injecting drug use and needle sharing, commercial sex with low rates of condom use, and concurrent sex with both commercial sex workers and noncom- mercial casual or steady sex partners. In addition, there are increasing “double risk” populations overlapping drug users and sex workers, as well as increasing rates of STDs and HIV among high-risk populations. Sexual transmission, therefore, may serve as a bridge connecting high-risk populations with general populations. There is an urgent need to prevent the spread of HIV from these high-risk populations into the general population of China.Tuo Fu ZHU Chun Hui WANG Peng LIN Na HE 2005Cell Research2005,15,11:10
11Combination of mild therapeutic hypothermia and adipose-derived stem cells for ischemic brain injury显示文摘Mild therapeutic hypothermia has been shown to mitigate cerebral ischemia, reduce cerebral edema, and improve the prognosis of patients with cerebral ischemia. Adipose-derived stem cell-based therapy can decrease neuronal death and infiltration of inflammatory cells, exerting a neuroprotective effect. We hypothesized that the combination of mild therapeutic hypothermia and adipose-derived stem cells would be neuroprotective for treatment of stroke. A rat model of transient middle cerebral artery occlusion was established using the nylon monofilament method. Mild therapeutic hypothermia(33°C) was induced after 2 hours of ischemia. Adipose-derived stem cells were administered through the femoral vein during reperfusion. The severity of neurological dysfunction was measured by a modified Neurological Severity Score Scaling System. The area of the infarct lesion was determined by 2,3,5-triphenyltetrazolium chloride staining. Apoptotic neurons were detected by terminal deoxynucleotidyl transferase-mediated d UTP-biotin nick end labeling(TUNEL) staining. The regeneration of microvessels and changes in the glial scar were detected by immunofluorescence staining. The inflammatory responses after ischemic brain injury were evaluated by in situ staining using markers of inflammatory cells. The expression of inflammatory cytokines was measured by reverse transcription-polymerase chain reaction. Compared with mild therapeutic hypothermia or adipose-derived stem cell treatment alone, their combination substantially improved neurological deficits and decreased infarct size. They synergistically reduced the number of TUNEL-positive cells and glial fibrillary acidic protein expression, increased vascular endothelial growth factor levels, effectively reduced inflammatory cell infiltration and down-regulated the m RNA expression of the proinflammatory cytokines interleukin-1β, tumor necrosis factor-α and interleukin-6. Our findings indicate that combined treatment is a better approach for treating stroke compared with mild therapeutic hypothermia or adipose-derived stem cells alone.Kai Zhao Rui Li Sheng Bi Yu Li Long Liu Yu-Long Jia Peng Han Chang-Cong Gu Xi-Ze Guo Wan-Ping Zhang Chun Wang Chun-Ying Pei Lin-Lu Tian Li-Xian Li 2018Neural Regeneration Research2018,13,10:9

16Involvement of midgastric transverse band in gastric empting delay of functional dyspepsia显示文摘Background Midgastric transverse band (MTB) was first observed over 100 years ago, after that many researchers worked on the subject postulated its physiologic role and the role in gastrointestinal diseases, but its function remains unclear. With progress of imaging methods, the nature of MTB is unveiling. In this study we investigated the effect of MTB on the gastric empting delay in functional dyspepsia (FD) and explored the mechanism. Methods A total of 60 patients with FD and 65 age- and sex-matched healthy people who served as controls were studied. With 99mTc-DTPA labeled semi-solid fat-parched flour served as test meal, gastric empting was examined in all subjects by using single photon emission computed tomography. Test meal was designated as general (60 g fat-parched flour) or large (80 g fat-parched flour) meal. Stomach was divided into proximal and distal parts by MTB. Half gastric empting time, areas of different gastric parts, intragastric food distribution and MTB width were tested with in given times. Results Patients with FD showed a delayed gastric empting and increased intragastric residue. Global and regional gastric empting velocity was decreased. The areas of distal stomach and MTB were significantly greater in the FD patients than in the controls. Throughout the whole test period a distal stomach-dominated food distribution was shown. Those who took a large meal had longer half gastric empting time and greater MTB area than those who took a general meal. Conclusions Gastric empting delay is related to enlarged MTB area. Some dyspeptic symptoms may be induced by abnormal distribution and increased retention of food in distal stomach. MTB, being like atria-ventricular valve that controls blood flow in heart, regulates transport, distribution, and empting of food in the stomach.YAN Xiang LIU Chun LIU Yong-ming YANG Peng CHEN Da-an CHEN Ming WANG Jing WANG Jin-yang LIU Rong 2005Chinese Medical Journal2005,,15:8

20Loss of Gn1a/OsCKX2 confers heavy-panicle rice with excellent lodging resistance显示文摘Significant achievements have been made in breeding programs for the heavy-panicle-type(HPT)rice(Oryza sativa) in Southwest China. The HPT varieties now exhibit excellent lodging resistance,allowing them to overcome the greater pressures caused by heavy panicles. However, the genetic mechanism of this lodging resistance remains elusive. Here, we isolated a major quantitative trait locus, Panicle Neck Diameter 1(PND1), andidentified the causal gene as GRAIN NUMBER 1 A/CYTOKININ OXIDASE 2(Gn1 A/Os CKX2). The null gn1 a allele from rice line R498(gn1 aR498) improved lodging resistance through increasing the culm diameter and promoting crown root development.Loss-of-function of Gn1 a/Os CKX2 led to cytokinin accumulation in the crown root tip and accelerated the development of adventitious roots. Gene pyramiding between the null gn1 aR498 allele with two gain-of-function alleles, STRONG CULM 2(SCM2)and SCM3, further improved lodging resistance.Moreover, Gn1 a/Os CKX2 had minimal influence on overall rice quality. Our research thus highlights the distinct genetic components of lodging resistance of HPT varieties and provides a strategy for tailormade crop improvement of both yield and lodging resistance in rice.Bin Tu Zhang Tao Shiguang Wang Lei Zhou Ling Zheng Chun Zhang Xinzi Li Xiaoyu Zhang Junjie Yin Xiaobo Zhu Hua Yuan Ting Li Weilan Chen Peng Qin Bingtian Ma Yuping Wang Shigui Li 2022Journal of Integrative Plant Biology2022,64,1:5
