6Effects of maize-soybean relay intercropping on crop nutrient uptake and soil bacterial community显示文摘Maize-soybean relay intercropping is an effective approach to improve the crop yield and nutrient use efficiency,which is widely practiced by farmers in southwest of China.To elucidate the characteristics of different planting patterns on crop nutrient uptake,soil chemical properties,and soil bacteria community in maize-soybean relay intercropping systems,we conducted a field experiment in 2015–2016 with single factor treatments,including monoculture maize(MM),monoculture soybean(MS),maize-soybean relay intercropping(IMS),and fallow(CK).The results showed that the N uptake of maize grain increased in IMS compared with MM.Compared with MS,the yield and uptake of N,P,and K of soybean grain were increased by 25.5,24.4,9.6,and 22.4%in IMS,respectively,while the N and K uptakes in soybean straw were decreased in IMS.The soil total nitrogen,available phosphorus,and soil organic matter contents were significantly higher in IMS than those of the corresponding monocultures and CK.Moreover,the soil protease,soil urease,and soil nitrate reductase activities in IMS were higher than those of the corresponding monocultures and CK.The phyla Proteobacteria,Acidobacteria,Chloroflexi,and Actinobacteria dominated in all treatments.Shannon’s index in IMS was higher than that of the corresponding monocultures and CK.The phylum Proteobacteria proportion was positively correlated with maize soil organic matter and soybean soil total nitrogen content,respectively.These results indicated that the belowground interactions increased the crop nutrient(N and P)uptake and soil bacterial community diversity,both of which contributed to improved soil nutrient management for legume-cereal relay intercropping systems.FU Zhi-dan ZHOU Li CHEN Ping DU Qing PANG Ting SONG Chun WANG Xiao-chun LIU Wei-guo YANG Wen-yu YONG Tai-wen 2019Journal of Integrative Agriculture2019,18,9:17
7Two surgical procedures for esophagogastric variceal bleeding in patients with portal hypertension显示文摘AIM:To determine the clinical value of a splenorenal shunt plus pericardial devascularization(PCVD)in portal hypertension(PHT)patients with variceal bleeding.METHODS:From January 2008 to November 2012,290 patients with cirrhotic portal hypertension were treated surgically in our department for the prevention of gastroesophageal variceal bleeding:207 patients received a routine PCVD procedure(PCVD group),and83 patients received a PCVD plus a splenorenal shunt procedure(combined group).Changes in hemodynamic parameters,rebleeding,encephalopathy,portal vein thrombosis,and mortality were analyzed.RESULTS:The free portal pressure decreased to 21.43±4.35 mmHg in the combined group compared with24.61±5.42 mmHg in the PCVD group(P<0.05).The changes in hemodynamic parameters were more significant in the combined group(P<0.05).The long-term rebleeding rate was 7.22%in the combined group,which was lower than that in the PCVD group(14.93%),(P<0.05).CONCLUSION:Devascularization plus splenorenal shunt is an effective and safe strategy to control esophagogastric variceal bleeding in PHT.It should be recommended as a first-line treatment for preventing bleeding in PHT patients when surgical interventions are considered.Lin Yang Li-Juan Yuan Rui Dong Ji-Kai Yin Qing Wang Tao Li Jiang-Bin Li Xi-Lin Du Jian-Guo Lu 2013World Journal of Gastroenterology2013,19,48:15
8Optimized nitrogen application methods to improve nitrogen use efficiency and nodule nitrogen fixation in a maize-soybean relay intercropping system显示文摘In China, the abuse of chemical nitrogen(N) fertilizer results in decreasing N use efficiency(NUE), wasting resources and causing serious environmental problems. Cereal-legume intercropping is widely used to enhance crop yield and improve resource use efficiency, especially in Southwest China. To optimize N utilization and increase grain yield, we conducted a two-year field experiment with single-factor randomized block designs of a maize-soybean intercropping system(IMS). Three N rates, NN(no nitrogen application), LN(lower N application: 270 kg N ha–1), and CN(conventional N application: 330 kg N ha–1), and three topdressing distances of LN(LND), e.g., 15 cm(LND1), 30 cm(LND2) and 45 cm(LND3) from maize rows were evaluated. At the beginning seed stage(R5), the leghemoglobin content and nitrogenase activity of LND3 were 1.86 mg plant–1 and 0.14 m L h–1 plant–1, and those of LND1 and LND2 were increased by 31.4 and 24.5%, 6.4 and 32.9% compared with LND3, respectively. The ureide content and N accumulation of soybean organs in LND1 and LND2 were higher than those of LND3. The N uptake, NUE and N agronomy efficiency(NAE) of IMS under CN were 308.3 kg ha–1, 28.5%, and 5.7 kg grain kg–1 N, respectively; however, those of LN were significantly increased by 12.4, 72.5, and 51.6% compared with CN, respectively. The total yield in LND1 and LND2 was increased by 12.3 and 8.3% compared with CN, respectively. Those results suggested that LN with distances of 15–30 cm from the topdressing strip to the maize row was optimal in maize-soybean intercropping. Lower N input with an optimized fertilization location for IMS increased N fixation and N use efficiency without decreasing grain yield.YONG Tai-wen CHEN Ping DONG Qian DU Qing YANG Feng WANG Xiao-chun LIU Wei-guo YANG Wen-yu 2018Journal of Integrative Agriculture2018,17,3:15
9Chemical and optical properties of aerosols and their interrelationship in winter in the megacity Shanghai of China显示文摘A field campaign on air quality was carried out in Shanghai in winter of 2012. The concentrations of NO, NO2, NOx, SO2, CO, and PM2.5increased during haze formation. The average masses of SO42-, NO3-and NH4+were 10.3, 11.7 and 6.7 μg/m3 during the haze episodes, which exceeded the average(9.2, 7.9, and 3.4 μg/m3) of these components in the non-haze days. The mean values for the aerosol scattering coefficient(b sp), aerosol absorption coefficient(b ap) and single scattering albedo(SSA) were 288.7, 27.7 and0.91 Mm-1, respectively. A bi-peak distribution was observed for the mass concentrations of CO, NO, NO2, and NOx. More sulfate was produced during daytime than that in the evening due to photochemical reactions. The mass concentration of NH4+achieved a small peak at noontime. NO3-showed lower concentrations in the afternoon and higher concentrations in the early morning. There were obvious bi-peak diurnal patterns for b sp and b ap as well as SSA. b sp and b ap showed a positive correlation with PM2.5mass concentration.(NH4)2SO4, NH4NO3, organic mass, elemental carbon and coarse mass accounted for 21.7%, 19.3%, 31.0%, 9.3% and 12.3% of the total extinction coefficient during non-haze days, and 25.6%, 24.3%, 30.1%, 8.1% and 8.2% during hazy days. Organic matter was the largest contributor to light extinction. The contribution proportions of ammonium sulfate and ammonium nitrate to light extinction were significantly higher during the hazy time than during the non-haze days.Tingting Han Liping Qiao Min Zhou Yu Qu Jianfei Du Xingang Liu Shengrong Lou Changhong Chen Hongli Wang Fang Zhang Qing Yu Qiong Wu 2015Journal of Environmental Sciences2015,27,1:14
10ZmCOL3, a CCT gene represses flowering in maize by interfering with the circadian clock and activating expression of ZmCCT显示文摘Flowering time is a trait vital to the adaptation of flowering plants to different environments.Here, we report that CCT domain genes play an important role in flowering in maize(Zea mays L.).Among the 53 CCT family genes we identified in maize, 28 were located in flowering time quantitative trait locus regions and 15 were significantly associated with flowering time, based on candidate-gene association mapping analysis.Furthermore, a CCT gene named ZmCOL3 was shown to be a repressor of flowering.Overexpressing ZmCOL3 delayed flowering time by approximately 4 d, in either long-day or short-day conditions.The absence of one cytosine in the ZmCOL3 3'UTR and the presence of a 551 bp fragment in the promoter region are likely the causal polymorphisms contributing to the maize adaptation from tropical to temperate regions.We propose a modified model of the maize photoperiod pathway, wherein ZmCOL3 acts as an inhibitor of flowering either by transactivating transcription of ZmCCT, one of the key genes regulating maize flowering, or by interfering with the circadian clock.Minliang Jin Xiangguo Liu Wei Jia Haijun Liu Wenqiang Li Yong Peng Yanfang Du Yuebin Wang Yuejia Yin Xuehai Zhang Qing Liu Min Deng Nan Li Xiyan Cui Dongyun Hao Jianbing Yan 2018Journal of Integrative Plant Biology2018,60,6:14
11Mechanisms responsible for the effect of median nerve electrical stimulation on traumatic brain injuryinduced coma: orexin-A-mediated N-methyl-Daspartate receptor subunit NR1 upregulation显示文摘Electrical stimulation of the median nerve is a noninvasive technique that facilitates awakening from coma. In rats with traumatic brain injury-induced coma, median nerve stimulation markedly enhances prefrontal cortex expression of orexin-A and its receptor, orexin receptor 1. To further understand the mechanism underlying wakefulness mediated by electrical stimulation of the median nerve, we evaluated its effects on the expression of the N-methyl-D-aspartate receptor subunit NR1 in the prefrontal cortex in rat models of traumatic brain injury-induced coma, using immunohistochemistry and western blot assays. In rats with traumatic brain injury, NR1 expression increased with time after injury. Rats that underwent electrical stimulation of the median nerve(30 Hz, 0.5 ms, 1.0 m A for 15 minutes) showed elevated NR1 expression and greater recovery of consciousness than those without stimulation. These effects were reduced by intracerebroventricular injection of the orexin receptor 1 antagonist SB334867. Our results indicate that electrical stimulation of the median nerve promotes recovery from traumatic brain injury-induced coma by increasing prefrontal cortex NR1 expression via an orexin-A-mediated pathway.Zhen Feng Qing Du 2016Neural Regeneration Research2016,11,6:13

13Serum Uric Acid is Associated with the Predicted Risk of Prevalent Cardiovascular Disease in a Community-dwelling Population without Diabetes显示文摘Objective To examine the association between serum uric acid levels and cardiovascular disease risk among individuals without diabetes. Methods We investigated the association between serum uric acid levels and the risk of prevalent cardiometabolic diseases, 10-year Framingham risk for coronary heart disease, and 10-year risk for atherosclerotic cardiovascular diseases(ASCVD) among 8,252 participants aged ≥ 40 years without diabetes from Jiading district, Shanghai, China. Results Body mass index, waist circumference, blood glucose, glycated hemoglobin, blood pressure, and serum lipids increased progressively across the sex-specific quartiles of uric acid(all P trend < 0.05). Compared with individuals in the lowest quartile, those in the higher quartiles had a significantly higher prevalence of obesity, hypertension, and dyslipidemia(all P trend < 0.05). A fully adjusted logistic regression analysis revealed that individuals in the highest quartile had an increased risk of predicted cardiovascular disease compared with those in the lowest quartile of uric acid. The multivariate adjusted odds ratios(ORs) [95% confidence intervals(CIs)] for the highest quartiles for high Framingham risk were 3.00(2.00-4.50) in men and 2.95(1.08-8.43) in women. The multivariate adjusted ORs(95% CIs) for the highest quartile for high ASCVD risk were 1.93(1.17-3.17) in men and 4.53(2.57-7.98) in women. Conclusion Serum uric acid level is associated with an increased risk of prevalent obesity, hypertension, dyslipidemia, 10-year Framingham risk for coronary heart disease, and 10-year risk for ASCVD among Chinese adults without diabetes.CHENG Di DU Rui WU Xue Yan LIN Lin PENG Kui MA Li Na XU Yu XU Min CHEN Yu Hong BI Yu Fang WANG Wei Qing DAI Meng LU Jie Li 2018Biomedical and Environmental Sciences2018,31,2:13
14Management of granulomatous lobular mastitis: an international multidisciplinary consensus(2021 edition)显示文摘Granulomatous lobular mastitis(GLM) is a rare and chronic benign inflammatory disease of the breast. Difficulties exist in the management of GLM for many front-line surgeons and medical specialists who care for patients with inflammatory disorders of the breast. This consensus is summarized to establish evidence-based recommendations for the management of GLM. Literature was reviewed using PubMed from January 1, 1971 to July 31, 2020. Sixty-six international experienced multidisciplinary experts from 11 countries or regions were invited to review the evidence.Levels of evidence were determined using the American College of Physicians grading system, and recommendations were discussed until consensus. Experts discussed and concluded 30 recommendations on historical definitions,etiology and predisposing factors, diagnosis criteria, treatment, clinical stages, relapse and recurrence of GLM. GLM was recommended as a widely accepted definition. In addition, this consensus introduced a new clinical stages and management algorithm for GLM to provide individual treatment strategies. In conclusion, diagnosis of GLM depends on a combination of history, clinical manifestations, imaging examinations, laboratory examinations and pathology.The approach to treatment of GLM should be applied according to the different clinical stage of GLM. This evidencebased consensus would be valuable to assist front-line surgeons and medical specialists in the optimal management of GLM.Qian-Qian Yuan Shu-Yuan Xiao Omar Farouk Yu-Tang Du Fereshte Sheybani Qing Ting Tan Sami Akbulut Kenan Cetin Afsaneh Alikhassi Rami Jalal Yaghan Irmak Durur-Subasi Fatih Altintoprak Tae Ik Eom Fatih Alper Mustafa Hasbahceci David Martínez-Ramos Pelin Seher Oztekin Ava Kwong Cedric W.Pluguez-Turul Kirstyn EBrownson Shirish Chandanwale Mehran Habib Liu-Yi Lan Rui Zhou Xian-Tao Zeng Jiao Bai Jun-Wen Bai Qiong-Rong Chen Xing Chen Xiao-Ming Zha Wen-Jie Dai Zhi-Jun Dai Qin-Yu Feng Qing-Jun Gao Run-Fang Gao Bao-San Han Jin-Xuan Hou Wei Hou Hai-Ying Liao Hong Luo Zheng-Ren Liu Jing-Hua Lu Bin Luo Xiao-Peng Ma Jun Qian Jian-Yong Qin Wei Wei Gang Wei Li-Ying Xu Hui-Chao Xue Hua-Wei Yang Wei-Ge Yang Chao-Jie Zhang Fan Zhang Guan-Xin Zhang Shao-Kun Zhang Shu-Qun Zhang Ye-Qiang Zhang Yue-Peng Zhang Sheng-Chu Zhang Dai-Wei Zhao Xiang-Min Zheng Le-Wei Zheng Gao-Ran Xu Wen-Bo Zhou Gao-Song Wu 2022Military Medical Research2022,9,4:13
15Diurnal characteristics of geoelectric fields and their changes associated with the Alxa Zuoqi M_S5.8 earthquake on 15 April 2015(Inner Mongolia)显示文摘In China, efforts are being made to monitor geoelectric fields through a large network of stations deployed and managed by the China Earthquake Administration. The diurnal variations in the geoelectric field waveforms were similar in the quiet magnetic periods when K<5(generally, K<3 indicates a quiet time). The arrival time points of the maxima in the geoelectric field waveforms exhibited differences in local time related to geographic longitude. The amplitude of diurnal variation was several to 16.6 mV/km and decreased with increasing latitude. Further,the amplitude of diurnal variation, which was related to seasonal changes, was larger in summer and autumn than in spring and winter. The periods of diurnal changes during quiet days were 24, 12, 8, 6, 4 hours and several minutes over large areas. Finally, the observed diurnal variations in geoelectric field prior to the Alxa Zuoqi M_S5.8 earthquake on 15 April 2015 were studied, and pronounced changes in the spectral values of the geoelectric fields were found to be associated with the Alxa Zuoqi earthquake in Inner Mongolia.Qing Ye Ye Fan Xuebin Du Tengfa Cui Kechang Zhou Ramesh P.Singh 2018Earthquake Science2018,31,1:12

18Transcriptional landscape of rice roots at the single-cell resolution显示文摘There are two main types of root systems in flowering plants,namely taproot systems of dicots and fibrous root systems found in monocots.Despite this fundamental split,our current knowledge of cellular and molecular mechanism driving root development is mainly based on studies of the dicot model Arabidopsis.However,the world major crops are monocots and little is known about the transcriptional programs underlying cell-type specification in this clade.Here,we report the transcriptomes of more than 20000 single cells derived from root tips of two agronomically important rice cultivars.Using combined computational and experimental analyses we were able to robustly identify most of the major cell types and define novel cell-type-specific marker genes for both cultivars.Importantly,we found divergent cell types associated with specific regulatory programs,including phytohormone biosynthesis,signaling,and response,which were well conserved between the two rice cultivars.In addition,we detected substantial differences between the cell-type transcript profiles of Arabidopsis and rice.These species-specific features emphasize the importance of analyzing tissues across diverse model species,including rice.Taken together,our study provides insight into the transcriptomic landscape of major cell types of rice root tip at single-cell resolution and opens new avenues to study cell-type specification,function,and evolution in plants.Qing Liu Zhe Liang Dan Feng Sanjie Jiang Yifan Wang Zhuoying Du Ruoxi Li Guihua Hu Pingxian Zhang Yanfei Ma Jan ULohmann Xiaofeng Gu 2021Molecular Plant2021,14,3:9

20Isochlorogenic acid(ICGA): natural medicine with potentials in pharmaceutical developments显示文摘Natural products have attracted a great deal of attention as significant resources in traditional Chinese medicine(TCM)and in chemical medicine, as well as in cosmetic ingredients, nutraceuticals and food products. Isochlorogenic acid(ICGA), which has medicinal value, has been discovered in various plants. As a widespread natural medicine, ICGA should be the subject of further research and development. However, there have been no systematic analyses of ICGA. According to our investigation, ICGA was initially isolated from green coffee extracts by Barnes et al. in 1950. To date, it has been discovered in a variety of tea, vegetables, medicinal diet and TCM materials. ICGA is used as a chemical marker for the quality control of these TCM materials. The metabolic process of ICGA has been studied in detail, conforming to be linear dynamics. Thus, the clear pharmacokinetics of ICGA offers a solid foundation for its research and development. ICGA has multiple biological and pharmacological effects, and studies have mainly focused on its antioxidant, anti-inflammatory, antimicrobial, hypoglycemic, neuroprotective, and cardiovascular protective effects, and hepatoprotective properties. The mechanisms underlying these effects are summarized in this review to provide scientific support and inspiration for the future research and development of ICGA and ICGA-rich natural products.WANG Hao-Nan SHEN Zheng LIU Qing HOU Xiao-Ying CAO Yan LIU Da-Hui JIANG Hong DU Hong-Zhi 2020Chinese Journal of Natural Medicines2020,18,11:9
