1Effect of Soil Drought Stress on Leaf Water Status, Membrane Permeability and Enzymatic Antioxidant System of Maize显示文摘A simulation experiment on the responses of maize (Zea mays L.) from the third leaf stage to maturity for different soil water levels (well-watered, moderately stressed, and severely stressed) was conducted by controlling irrigation and using a mobile rain shelter in a neutral loam, meadow soil to determine the effects on leaf water status, membrane permeability and enzymatic antioxidant system for different growth stages. The results indicated that drought stress relied on drought intensity and duration, with more severe drought stress creating more serious effects on maize. Compared with well-watered conditions, during the silking and blister stages moderate stress did not significantly change the relative water content (RWC) and did change significantly the relative conductivity (RC) (P < 0.05) of the leaves; however, severe stress did significantly decrease (P < 0.01) the leaf RWC and increase (P < 0.01) membrane permeability (leaf relative conductivity). Furthermore, under severe drought stress antioxidant enzyme activities declined significantly (P < 0.01) in later stages, namely for superoxide dismutase (SOD) the tasseling and blister stages, for peroxidase (POD) the milk stage, and for catalase (CAT) during the tasseling, blister, and milk stages. Meanwhile, membrane lipid peroxidation (measured as malondialdehyde content) significantly increased (P < 0.01) in all stages.BAI Li-Ping SUI Fang-Gong GE Ti-Da SUN Zhao-Hui LU Yin-Yan ZHOU Guang-Sheng 2006Pedosphere2006,16,3:82
2Effects of Water Stress on the Protective Enzyme Activities and Lipid Peroxidation in Roots and Leaves of Summer Maize显示文摘A systematic study was conducted to determine the effects of water stress on the activities of protective enzymes and lipid peroxidation in maize. The results showed that, under water stress, the activities of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) in leaves and roots increased sharply at prophase and metaphase growth stages, such as, male tetrad stage, but then declined towards the physiological maturity. The protective enzyme activities in roots were lower than those in leaves. The content of malondialdehyde (MDA) increased according to the severity of water stress. The content of MDA in roots was lower than that in leaves. The activities of protective enzymes and lipid peroxidation in roots were positively related to that in leaves with most of the correlation coefficients being significant. The content of soluble proteins in roots and leaves decreased with increasing drought stress. The ear characteristics deteriorated and the economic yields of maize decreased significantly under water stress. The main factors that caused reduction of yields were the decrease in the number of ear kernels and 100-kernel weight.GE Ti-da SUI Fang-gong BAI Li-ping LU Yin-yan ZHOU Guang-sheng 2006Agricultural Sciences in China2006,5,4:26
3Altered trends in carbon uptake in China’s terrestrial ecosystems under the enhanced summer monsoon and warming hiatus显示文摘The carbon budgets in terrestrial ecosystems in China are strongly coupled with climate changes.Over the past decade,China has experienced dramatic climate changes characterized by enhanced summer monsoon and decelerated warming.However,the changes in the trends of terrestrial net ecosystem production(NEP)in China under climate changes are not well documented.Here,we used three ecosystem models to simulate the spatiotemporal variations in China's NEP during 1982–2010 and quantify the contribution of the strengthened summer monsoon and warming hiatus to the NEP variations in four distinct climatic regions of the country.Our results revealed a decadal-scale shift in NEP from a downtrend of–5.95 Tg C/yr^2(reduced sink)during 1982–2000 to an uptrend of 14.22 Tg C/yr^2(enhanced sink)during 2000–10.This shift was essentially induced by the strengthened summer monsoon,which stimulated carbon uptake,and the warming hiatus,which lessened the decrease in the NEP trend.Compared to the contribution of 56.3%by the climate effect,atmospheric CO2 concentration and nitrogen deposition had relatively small contributions(8.6 and 11.3%,respectively)to the shift.In conclusion,within the context of the global-warming hiatus,the strengthening of the summer monsoon is a critical climate factor that enhances carbon uptake in China due to the asymmetric response of photosynthesis and respiration.Our study not only revealed the shift in ecosystem carbon sequestration in China in recent decades,but also provides some insight for understanding ecosystem carbon dynamics in other monsoonal areas.Honglin He Shaoqiang Wang Li Zhang Junbang Wang Xiaoli Ren Lei Zhou Shilong Piao Hao Yan Weimin Ju Fengxue Gu Shiyong Yu Yuanhe Yang Miaomiao Wang Zhongen Niu Rcmg Ge Huimin Yan Mei Huang Guoyi Zhou Yongfei Bai Zongqiang Xie Zhiyao Tang Bingfang Wu Leiming Zhang Nianpeng He Qiufeng Wang Guirui Yu 2019National Science Review2019,6,3:24

5Effect of Kuanxiong Aerosol(宽胸气雾剂)on Patients with Angina Pectoris:A Non-inferiority Multi-center Randomized Controlled Trial显示文摘Objective: To evaluate the effect and safety of Kuanxiong Aerosol(宽胸气雾剂, KA) on patients with angina pectoris. Methods: Block randomization was performed to randomly allocate 750 patients into KA(376 cases) and control groups(374 cases). During an angina attack, the KA group received 3 consecutive sublingual sprays of KA(0.6 m L per spray). The control group received 1 sublingual nitroglycerin tablet(NT, 0.5 mg/tablet). Log-rank tests and Kaplan-Meier estimations were used to estimate the angina remission rates at 6 time-points after treatment(1, 2, 3, 4, 5, and >5 min). Logistic regression analysis was performed to observe the factors influencing the rate of effective angina remission, and the remission rates and incidences of adverse reactions were compared for different Canadian Cardiovascular Society(CCS) classes of angina. Results: The 5-min remission rates in the KA and control groups were not significantly different(94.41% vs. 90.64%, P>0.05). The angina CCS class significantly influenced the rate of remission (95% confidence interval = 0.483–0.740, P<0.01). In the CCS subgroup analysis, the 3-and 5-min remission rates for KA and NT were similar in the CCSⅠ and Ⅳ subgroups(P>0.05), while they were significantly better for KA in the CCSⅡ and Ⅲ subgroups(P<0.05 or P<0.01). Furthermore, the incidence of adverse reactions was significantly lower in the KA group than in the control group for the CCSⅡ and Ⅲ subgroups(9.29% vs. 26.22%, 10.13% vs. 20.88%, P<0.05 or P<0.01). Conclusions: KA is not inferior to NT in the remission of angina. Furthermore, in CCSⅡ and Ⅲ patients, KA is superior to NT, with a lower incidence of adverse reactions.YANG Qiao-ning BAI Rui-na DONG Guo-ju GE Chang-jiang ZHOU Jing-min HUANG Li HE Yan WANG Jun REN Ai-hua HUANG Zhan-quan ZHU Guang-li LU Shu XIONG Shang-quan XIAN Shao-xiang ZHU Zhi-jun SHI Da-zhuo LU Shu-zheng LI Li-zhi CHEN Ke-ji 2018Chinese Journal of Integrative Medicine2018,24,5:15

8Punicalagin ameliorates collagen-induced arthritis by downregulating M1 macrophage and pyroptosis via NF-κB signaling pathway显示文摘Rheumatoid arthritis(RA)is a chronic inflammatory disease that eventually leads to disability.Inflammatory cell infiltration,severe joint breaking and systemic bone loss are the main clinical symptoms.In this study,we established a collagen-induced arthritis(CIA)model and found a large number of M1 macrophages and pyroptosis,which are important sources of proinflammatory cytokines.Punicalagin(PUN)is an active substance extracted from pomegranate peel.We found that it inhibited joint inflammation,cartilage damage and systemic bone destruction in CIA mice.PUN effectively alleviated the high expression of inflammatory cytokines in synovial tissue in vivo.PUN treatment shifted macrophages from the M1 phenotype to the M2 phenotype after stimulation with lipopolysaccharide(LPS)and interferon(IFN)-γ.The expression of inducible nitric oxide synthase(i NOS)and other proinflammatory cytokines released by M1 macrophages was decreased in the PUN treatment group.However,simultaneously,the expression of markers of anti-inflammatory M2 macrophages,such as arginase(Arg)-1 and interleukin(IL)-10,was increased.In addition,PUN treatment attenuated pyroptosis by downregulating the expression of NLRP3 and caspase-1,thereby preventing inflammatory cell death resulting from the release of IL-1βand IL-18.Mechanistically,PUN inhibited the activation of receptor activators of the nuclear factor-κB(NF-κB)signaling pathway,which contributes to M1 polarization and pyroptosis of macrophages.We concluded that PUN ameliorated pathological inflammation by inhibiting M1 phenotype polarization and pyroptosis and has great potential as a therapeutic treatment for human RA.Gaoran Ge Jiaxiang Bai Qing Wang Xiaolong Liang Huaqiang Tao Hao Chen Minggang Wei Junjie Niu Huilin Yang Yaozeng Xu Yuefeng Hao Yi Xue Dechun Geng 2022Science China(Life Sciences)2022,65,3:14
9Soil Fertility,Microbial Biomass,and Microbial Functional Diversity Responses to Four Years Fertilization in an Apple Orchard in North China显示文摘Soil microbial communities play an essential role in maintaining soil fertility and are considered as ecological indicators to evaluate soil health.In the present study,we examined the influence of almost 4 years of fertilization[no fertilizer(CK),nitrogen alone(N),nitrogen,phosphorus and potassium chemical fertilizer(NPK),organicmanure(M),nitrogen plus organic manure(NM),and NPK plus organic manure(NPKM)]on soil fertility and the functional diversity of soil microbial communities in an apple orchard.Compared to CK,fertilization increased soil organic carbon,total nitrogen,and available nutrients,but reduced soil pH in N and NPK treatments.The highest microbial biomass carbon and nitrogen,most probable number of actinomycetes,bacteria,and fungi occurred in the NPKM treatment.The average well color development(AWCD)values followed the order of NPKM>M>NPK and NM>CK and N.The Shannon index in organic manure treatments were significantly higher than in control and in treatments without organic manure.The principal component analysis showed that manure treatment was significantly separated from other treatments.These results indicated that organic manure applied alone or in combination with chemical fertilizers would increase soil fertility and functional diversity of soil microbial communities.Moreover,applying balanced N,P,K fertilizer in combination with organic manure was found to be superior to the use of a single fertilizer in improving soil microbial community quality.Zhanling Zhu Yan Bai Minglu Lv Ge Tian Xin Zhang Li Li Yuanmao Jiang Shunfeng Ge 2020Horticultural Plant Journal2020,6,4:13
10Trachytic Rock and Associated Fenitization in the Bayan Obo Ore Deposit,Inner Mongolia,China:Evidence for Magmatic-Hydrothermal Mineralization Related to a Carbonatitic Complex显示文摘Trachytic rock and its altered rock-fenite-in the Bayan Obo ore district, Inner Mongolia, China, were referred to as slate or feldspar rock before, and identified by the authors for the first time (in 1992). In the paper the mineral assemblages, structures and textures and petrochemical compositions of the rocks, as well as the electron microprobe analysis of feldspars in the rocks are described. The Sm-Nd isochron age of the trachytic rock is 1096±56 Ma, with INd=0.51100+4 (2σ) and εNd(t)= -4.4±0.7. Alterations of the trachytic rock, including microclinization, riebeckitization, aegirinization and biotitization, and accompanied rare element and REE mineralizations are discussed. Based on the occurrence of the trachytic rock and associated fenitization it is deduced that the Bayan Obo Fe-Nb-REE ore deposit is genetically related to magmatic-hydrothermal activity of an alkali carbonatite complex.YUAN Zhongxin BAI Ge ZHANG Zongqing 2000Acta Geologica Sinica(English Edition)2000,74,2:13
11Seasonal and inter-annual variations in carbon fluxes and evapotranspiration over cotton field under drip irrigation with plastic mulch in an arid region of Northwest China显示文摘Xinjiang is the largest semi-arid and arid region in China, and drip irrigation under plastic mulch is widely used in this water-limited area. Quantifying carbon and water fluxes as well as investigating their environmental drivers over cotton fields is critical for understanding regional carbon and water budgets in Xinjiang, the largest cotton production basin of China. In this study, an eddy covariance(EC) technique was used to measure the carbon and water fluxes of cotton field under drip irrigation with plastic mulch in the growing seasons of 2009, 2010, 2012 and 2013 at Wulanwusu Agrometeorological Experiment Station, a representative oasis cropland in northern Xinjiang. The diurnal patterns of gross primary production(GPP), net ecosystem exchange(NEE) and evapotranspiration(ET) showed obviously sinusoidal variations from June to September, while the diurnal ecosystem respiration(Res) was stable between daytime and nighttime. The daytime hourly GPP and ET displayed asymptotic relationships with net solar radiation(Rnet), while showed concave patterns with raising vapor pressure deficit(VPD) and air temperature(Ta). The increases in hourly GPP and ET towards the maximum occurred over half ranges of VPD and Ta. The seasonal variations of GPP, NEE and ET were close to the cotton phenology, which almost reached the peak value in July. The cumulative GPP averaged 816.2±55.0 g C/m2 in the growing season(from April to October), and more than half of GPP was partitioned into NEE(mean value of –478.6±41.4 g C/m2). The mean seasonal ET was 501.3±13.9 mm, and the mean water use efficiency(WUE) was 1.0±0.1(mg C/g H2O)/d. The agro-ecosystem behaved as a carbon sink from squaring to harvest period, while it acted as a carbon source before the squaring time as well as after the harvest time.Jie BAI Jin WANG Xi CHEN Ge Ping LUO Hao SHI Long Hui LI Jun Li LI 2015Journal of Arid Land2015,7,2:12
12Landscape of DILI-related adverse drug reaction in China Mainland显示文摘Drug-induced liver injury(DILI)is a type of bizarre adverse drug reaction(ADR)damaging liver(L-ADR)which may lead to substantial hospitalizations and mortality.Due to the general low incidence,detection of L-ADR remains an unsolved public health challenge.Therefore,we used the data of 6.673 million of ADR reports from January 1st,2012 to December 31st,2016 in China National ADR Monitoring System to establish a new database of L-ADR reports for future investigation.Results showed that totally 114,357 ADR reports were retrieved by keywords searching of liver-related injuries from the original heterogeneous system.By cleaning and standardizing the data fields by the dictionary of synonyms and English translation,we resulted 94,593 ADR records reported to liver injury and then created a new database ready for computer mining.The reporting status of L-ADR showed a persistent 1.62-fold change over the past five years.The national population-adjusted reporting numbers of L-ADR manifested an upward trend with age increasing and more evident in men.The annual reporting rate of L-ADR in age group over 80 years old strikingly exceeded the annual DILI incidence rate in general population,despite known underreporting situation in spontaneous ADR reporting system.The percentage of herbal and traditional medicines(H/TM)L-ADR reports in the whole number was 4.5%,while 80.60%of the H/TM reports were new findings.There was great geographical disparity of reported agents,i.e.more cardiovascular and antineoplastic agents were reported in higher socio-demographic index(SDI)regions and more antimicrobials,especially antitubercular agents,were reported in lower SDI regions.In conclusion,this study presented a large-scale,unbiased,unified,and computer-minable L-ADR database for further investigation.Age-,sex-and SDI-related risks of L-ADR incidence warrant to emphasize the precise pharmacovigilance policies within China or other regions in the world.Jiabo Wang Haibo Song Feilin Ge Peng Xiong Jing Jing Tingting He Yuming Guo Zhuo Shi Chao Zhou Zixin Han Yanzhong Han Ming Niu Zhaofang Bai Guangbin Luo Chuanyong Shen Xiaohe Xiao 2022Acta Pharmaceutica Sinica B2022,12,12:12

14Ursolic acid reduces hepatocellular apoptosis and alleviates alcohol-induced liver injury via irreversible inhibition of CASP3 in vivo显示文摘Alcoholic liver disease (ALD) is one of the pathogenic factors of chronic liver disease with the highest clinical morbidity worldwide. Ursolic acid (UA), a pentacyclic terpenoid carboxylic acid, has shown many health benefits including antioxidative, anti- inflammatory, anticancer, and hepatoprotective activities. We previously found that UA was metabolized in vivo into epoxy- modified UA containing an epoxy electrophilic group and had the potential to react with nucleophilic groups. In this study we prepared an alkynyl-modified UA (AM-UA) probe for tracing and capturing the target protein of UA from liver in mice, then investigated the mode by which UA bound to its target in vivo. By conducting proteome identification and bioinformatics analysis, we identified caspase-3 (CASP3) as the primary target protein of UA associated with liver protection. Molecule docking analysis showed that the epoxy group of the UA metabolite reacted with Cys-163 of CASP3, forming a covalent bond with CASP3. The binding mode of the UA metabolites (UA, CM-UA, and EM-UA) was verified by biochemical evaluation, demonstrating that the epoxy group produced by metabolism played an important role in the inhibition of CASP3. In alcohol-treated HepG2 cells, pretreatment with the UA metabolite (10 μM) irreversibly inhibited CASP3 activities, and subsequently decreased the cleavage of PARP and cell apoptosis. Finally, pre-administration of UA (20–80 mg· kg−1 per day, ig, for 1 week) dose-dependently alleviated alcohol-induced liver injury in mice mainly via the inhibition of CASP3. In conclusion, this study demonstrates that UA is a valuable lead compound for the treatment of ALD.Xiao-yao Ma Man Zhang Ge Fang Chuan-jing Cheng Mu-kuo Wang Yi-man Han Xiao-tao Hou Er-wei Hao Yuan-yuan Hou Gang Bai 2021Acta Pharmacologica Sinica2021,42,7:11
15Landscape of Hepatobiliary Adverse Drug Reactions Related to Preparations Containing Psoraleae Fructus and Its Application in Pharmacovigilance显示文摘Objective To analyze clinical feature and information of medication to explore the risk signals of preparations containing Psoraleae Fructus(BGZP)related with hepatobiliary adverse drug reactions(ADR),in order to reinforce pharmacovigilance.Methods A retrospective study was conducted based on hepatobiliary ADR related with BGZP from the China Adverse Drug Reaction Monitoring System in years from January 2012 to December 2016.Serious and general ADRs were analyzed and assessed.Results There were 355 cases of hepatobiliary ADR related to BGZP.Both the amount of cases and the proportion of serious ADR showed an increasing growth by years(P<0.05).It was found that 10.43%of 355 cases may be involved with irrational drug use,including overdose,repeated medication,and combination of multiple drugs.There were 190 cases which used BGZP(non-combination),and they were mainly for common in diseases caused by abnormal immune activation(accounting for 40.53%of the total cases).Especially at the age group with the most cases with age of 41–50 years,the cases associated with immunological diseases of female were obviously more than that of male(P<0.05).The latency of hepatobiliary ADR related to BGZP ranged from 1 to 386 days,and the median latency was 27.5 days,along with the range of cumulative dose(0.45–520.02 g)as well as the daily dose(0.09–2.64 g/d)after the conversion.Conclusions Cases of hepatobiliary ADR related to BGZP showed significant individual differences,and there was no correlation between drug usage duration and dosage and the occurrence of hepatobiliary ADR.It may be similar with idiosyncratic drug-induced liver injury,and recommended that BGZP should be used with more caution under monitoring liver function,especially in female patients with immunological diseases.GE Fei-lin NIU Ming HAN Zi-xin CAO Jun-ling WANG Jia-bo BAI Zhao-fang SONG Hai-bo GUO Yu-ming XIAO Xiao-he 2021Chinese Journal of Integrative Medicine2021,27,11:8

17Hydrogen-rich saline protects against hepatic injury induced by ischemia-reperfusion and laparoscopic hepatectomy in swine显示文摘Background: Hydrogen-rich saline(HRS) has antioxidative, anti-inflammatory and anti-apoptotic properties. We investigated the effects of hydrogen on hepatic ischemia-reperfusion(I/R) and laparoscopic hepatectomy in swine. Methods: Twenty-one healthy Bama miniature pigs were randomly divided into the sham group, ischemia-reperfusion injury(IRI) group, HRS-5(5 m L/kg) group, and HRS-10(10 m L/kg) group. HRS was injected through the portal vein 10 min before reperfusion and at postoperative day 1, 2 and 3. The roles of HRS on oxidative stress, inflammatory response and liver regeneration were studied. Results: Compared with the IRI group, HRS treatment attenuated oxidative stress by increasing catalase activity and reducing myeloperoxidase. White blood cells in the HRS-10 group were reduced compared with the IRI group( P < 0.01). In the HRS-10 group, interleukin-1 beta, interleukin-6 and tumor necrosis factor alpha, C-reactive protein and cortisol were downregulated, whereas interleukin-10 was upregulated. In addition, HRS attenuated endothelial cell injury and promoted the secretion of angiogenic cytokines, including vascular endothelial growth factor, angiopoietin-1 and angiopoietin-2. HRS elevated the levels of hepatocyte growth factor, Cyclin D1, proliferating cell nuclear antigen, Ki-67 and reduced the secretion of transforming growth factor-beta. Conclusions: HRS treatment may exert a protective effect against I/R and hepatectomy-induced hepatic damage by reducing oxidative stress, suppressing the inflammatory response and promoting liver regeneration.Yan-Song Ge Qian-Zhen Zhang Hui Li Ge Bai Zhi-Hui Jiao Hong-Bin Wang 2019Hepatobiliary & Pancreatic Diseases International2019,18,1:8
18Predictors of adherence to home-based cardiac rehabilitation program among coronary artery disease outpatients in China显示文摘Background Cardiac rehabilitation (CR) has proven beneficial for patients with coronary artery disease. However, adherence to CR programs is the key to the health improvement in those patients. Identifying predictors for adherence, which is very much unknown in China, would be valuable for effective rehabilitation. This study aims to determine the adherence to home-based CR programs in Chinese coronary artery disease patients and determine predictors of adherence. Methods The current study included 1033 outpatients with coronary heart disease in the First Medical Center of Chinese PLA General Hospital in Beijing from July 2015 to June 2017. Participants were given an exercise prescription and took part in home-based exercise training lasting for 3–24 months. A questionnaire was used to evaluate the completion of the CR program, understanding of the program, motivation of the patients, and family/peer support. Results Two thirds of the patients adhered well to the home-based CR program. Elder patients (≥ 65-year-old) adhere to the program better, while men adhered better than women. Patients who used to exercise (B = 6.756, P < 0.001), understood the program (B = 0.078, P = 0.002), with stronger motivation to participate (B = 0.376, P < 0.001), and received better family support (B = 0.487, P < 0.001) also adhere better to the program. Conclusions Understanding the program, self-motivation of patients, and family support help to keep patients engaged in a home-based CR program. Improvement of family support by educating both patients and families may be helpful in improving adherence to home-based CR programs.Cheng GE Jing MA Yong XU Ya-Jun SHI Cheng-Hui ZHAO Ling GAO Jing BAI Yu WANG Zhi-Jun SUN Jun GUO Yun-Dai CHEN 2019Journal of Geriatric Cardiology2019,16,10:8

20Quantitative energy-dispersive X-ray fluorescence analysis for unknown samples using full-spectrum least-squares regression显示文摘The full-spectrum least-squares(FSLS) method is introduced to perform quantitative energy-dispersive X-ray fluorescence analysis for unknown solid samples.Based on the conventional least-squares principle, this spectrum evaluation method is able to obtain the background-corrected and interference-free net peaks, which is significant for quantization analyses. A variety of analytical parameters and functions to describe the features of the fluorescence spectra of pure elements are used and established, such as the mass absorption coefficient, the Gi factor, and fundamental fluorescence formulas. The FSLS iterative program was compiled in the C language. The content of each component should reach the convergence criterion at the end of the calculations. After a basic theory analysis and experimental preparation, 13 national standard soil samples were detected using a spectrometer to test the feasibility of using the algorithm. The results show that the calculated contents of Ti, Fe, Ni, Cu, and Zn have the same changing tendency as the corresponding standard content in the 13 reference samples. Accuracies of 0.35% and 14.03% are obtained, respectively, for Fe and Ti, whose standard concentrations are 8.82% and 0.578%, respectively. However, the calculated results of trace elements (only tens of lg/g) deviate from the standard values. This may be because of measurement accuracy and mutual effects between the elements.Yong-Li Liu Qing-Xian Zhang Jian Zhang Hai-Tao Bai Liang-Quan Ge 2019Nuclear Science and Techniques2019,30,3:6
