| 2 | ZmMs30 Encoding a Novel GDSL Lipase Is Essential for Male Fertility and Valuable for Hybrid Breeding in Maize显示文摘Genic male sterility (GMS) is very useful for hybrid vigor utilization and hybrid seed production. Although a large number of GMS genes have been identified in plants, little is known about the roles of GDSL lipase members in anther and pollen development. Here, we report a maize GMS gene, ZmMs30, which encodes a novel type of GDSL lipase with diverged catalytic residues. Enzyme kinetics and activity assays show that ZmMs30 has lipase activity and prefers to substrates with a short carbon chain. ZmMs30 is specifically expressed in maize anthers during stages 7-9. Loss of ZmMs30 function resulted in defective anther cuticle, irregular foot layer of pollen exine, and complete male sterility. Cytological and lipidomics analyses demonstrate that ZmMs30 is crucial for the aliphatic metabolic pathway required for pollen exine formation and anther cuticle development. Furthermore, we found that male sterility caused by loss of ZmMs30 function was stable in various inbred lines with different genetic background, and that it didn't show any negative effect on maize heterosis and production, suggesting that ZmMs30 is valuable for crossbreeding and hybrid seed production. We then developed a new multi-control sterility system using ZmMs30 and its mutant line, and demonstrated it is feasible for generating desirable GMS lines and valu. able for hybrid maize seed production. Taken together, our study sheds new light on the mechanisms of anther and pollen development, and provides a valuable male-sterility system for hybrid breeding maize. | Xueli An Zhenying Dong Youhui Tian Ke Xie Suowei Wu Taotao Zhu Danfeng Zhang Van Zhou Canfang Niu Biao Ma Quancan Hou Jianxi Bao Simiao Zhang Ziwen Li Yanbo Wang Tingwei Yan Xiaojing Sun Yuwen Zhang Jinping Li Xiangyuan Wan | 2019 | Molecular Plant2019,12,3: | 15 |
| 3 | Interactive effects of soil temperature and moisture on soil N mineralization in a Stipa krylovii grassland in Inner Mongolia, China显示文摘Determining soil N mineralization response to soil temperature and moisture changes is challenging in the field due to complicated effects from other factors. In the laboratory, N mineralization is highly dependent on temperature, moisture and sample size. In this study, a laboratory incubation experiment was carefully designed and conducted under controlled conditions to examine the effects of soil temperature and moisture on soil N mineralization using soil samples obtained from the Stipa krylovii grassland in Inner Mongolia, China. Five temperature(i.e. 9°C, 14°C, 22°C, 30°C and 40°C) and five moisture levels(i.e. 20%, 40%, 60%, 80% and 100% WHC, where WHC is the soil water holding capacity) were included in a full-factorial design. During the 71-day incubation period, microbial biomass carbon(MBC), ammonium nitrogen(NH4 +-N) and nitrate nitrogen(NO3--N) were measured approximately every 18 days; soil basal respiration for qCO2 index was measured once every 2 days(once a week near the end of the incubation period). The results showed that the mineral N production and net N mineralization rates were positively correlated with temperature; the strongest correlation was observed for temperatures between 30°C and 40°C. The relationships between moisture levels and both the mineral N production and net N mineralization rates were quadratic. The interaction between soil temperature and moisture was significant on N mineralization, i.e. increasing temperatures(moisture) enhanced the sensitivity of N mineralization to moisture(temperature). Our results also showed a positive correlation between the net nitrification rate and temperature, while the correlation between the NH4 +-N content and temperature was insignificant. The net nitrification rate was negatively correlated with high NH4 +-N contents at 80%–100% WHC, suggesting an active denitrification in moist conditions. Moreover, qCO2 index was positively correlated with temperature, especially at 80% WHC. With a low net nitrification rate and high soil basal respiration rate, it was likely that the denitrification concealed the microbial gross mineralization activity; therefore, active soil N mineralization occurred in 60%–80% WHC conditions. | Yue LI YingHui LIU YaLin WANG Lei NIU Xia XU YuQiang TIAN | 2014 | Journal of Arid Land2014,6,5: | 12 |

| 5 | Identification and Characterization of Sulfur Compounds in Straight-Run Diesel Using Comprehensive Two-Dimensional GC Coupled with TOF MS显示文摘The solid-phase extraction using Pd-Al2O3 as the stationary phase was employed to pre-separate the sulfur compounds in straight-run diesel. The isolating effect was evaluated quantitatively by gas chromatography with a sulfur chemiluminescence detector to harvest a satisfactory result. The identification of the structure of sulfur compounds by comprehensive two-dimensional gas chromatography coupled with the time-of-flight mass spectrometry indicated that cyclo-sulfides, benzothiophenes, dibenzothiophenes, dihydro-benzothiophenes and tetrahydro-dibenzothiophenes were included in straightrun diesel obtained from the Arab medium crude(AM). A total of 259 individual compounds were detected and their molecular structures were identified. The analytical method was approved as an effective way to characterize the composition of sulfur compounds, which reduced the interference of other compounds, facilitated the data presentation and provided more detailed information about molecular composition of sulfur compounds. | Niu Luna Liu Zelong Tian Songbai | 2014 | China Petroleum Processing & Petrochemical Technology2014,16,3: | 10 |
| 6 | Essential roles of exosome and circRNA_101093 on ferroptosis desensitization in lung adenocarcinoma显示文摘Background:Resistance to ferroptosis,a regulated cell death caused by irondependent excessive accumulation of lipid peroxides,has recently been linked to lung adenocarcinoma(LUAD).Intracellular antioxidant systems are required for protection against ferroptosis.The purpose of the present studywas to investigate whether and how extracellular system desensitizes LUAD cells to ferroptosis.Methods:Established human lung fibroblasts MRC-5,WI38,and human LUAD H1650,PC9,H1975,H358,A549,and H1299 cell lines,tumor and matched normal adjacent tissues of LUAD,and plasma from healthy individuals and LUAD patients were used in this study.Immunohistochemistry and immunoblotting were used to analyze protein expression,and quantitative reverse transcription-PCR was used to analyze mRNA expression.Cell viability,cell death,and the lipid reactive oxygen species generationwere measured to evaluate the responses to ferroptosis.Exosomes were observed using transmission electron microscope.The localization of arachidonic acid(AA)was detected using click chemistry labeling followed by confocal microscopy.Interactions between RNAs and proteins were detected using RNA pull-down,RNA immunoprecipitation and photoactivatable ribonucleoside-enhanced crosslinking and immunoprecipitation methods.Proteomic analysis was used to investigate RNA-regulated proteins,and metabolomic analysis was performed to analyze metabolites.Cellderived xenograft,patient-derived xenograft,cell-implanted intrapulmonary LUAD mouse models and plasma/tissue specimens from LUAD patients were used to validate the molecular mechanism.Results:Plasma exosome from LUAD patients specifically reduced lipid peroxidation and desensitized LUAD cells to ferroptosis.A potential explanation is that exosomal circRNA_101093(cir93)maintained an elevation in intracellular cir93 in LUAD to modulate AA,a poly-unsaturated fatty acid critical for ferroptosisassociated increased peroxidation in the plasma membrane.Mechanistically,cir93 interacted with and increased fatty acid-binding protein 3(FABP3),which transported AA and facilitated its reaction with taurine.Thus,global AA was reduced,whereas N-arachidonoyl taurine(NAT,the product of AA and taurine)was induced.Notably,the role of NAT in suppressing AA incorporation into the plasma membrane was also revealed.In pre-clinical in vivo models,reducing exosome improved ferroptosis-based treatment.Conclusion:Exosome and cir93 are essential for desensitizing LUAD cells to ferroptosis,and blocking exosome may be helpful for future LUAD treatment. | Xiao Zhang Yunhua Xu Lifang Ma Keke Yu Yongjie Niu Xin Xu Yi Shi Susu Guo Xiangfei Xue Yikun Wang Shiyu Qiu Jiangtao Cui Hong Wang Xiaoting Tian Yayou Miao Fanyu Meng Yongxia Qiao Yongchun Yu Jiayi Wang | 2022 | Cancer Communications2022,42,4: | 10 |

| 9 | Diamond Discovered in High-Al Chromitites of the Sartohay Ophiolite,Xinjiang Province,China显示文摘In recent years diamonds and other exotic minerals have been recovered from mantle peridotites and high-Cr chromitites of a number of ophiolites of different age and different tectonic environments. Here we report a similar collection of minerals from the Sartohay ophiolite of Xinjiang Province,western China,which is characterized by having high-Al chromitites. Several samples of massive podiform chromitite with an aggregate weight of nearly 900 kg yielded diamonds,moissanite and other highly reduced minerals,as well as common crustal minerals. Thus far,more than 20 grains each of diamond and moissanite have been recovered from heavy mineral separates of the chromitites. The diamonds are all 100-200 μm in size and range in color from pale yellow to reddish-orange to colorless. Most of the grains are anhedral to subhedral octahedra,commonly with elongate forms exhibiting well-developed striations. They all display characteristic Raman spectra with shifts between 1325 cm-1 and 1333 cm-1,mostly 1331.51 cm-1 or 1326.96 cm-1. The moissanite grains are light blue to dark blue,broken crystals,50-150 μm across,commonly occurring as small flakes or fragments. Their typical Raman spectra have shifts at 762 cm-1,785 cm-1,and 966 cm-1. This investigation extends the occurrence of diamonds and moissanite to a Paleozoic ophiolite in the Central Asian Orogenic Belt and demonstrates that these minerals can also occur in high-Al chromitites. We conclude that diamonds and moissanite are likely to be ubiquitous in ophiolitic mantle peridotites and chromitites. | TIAN Yazhou YANG Jingsui Paul T.ROBINSON XIONG Fahui LI Yuan ZHANG Zhongming LIU Zhao LIU Fei NIU Xiaolu | 2015 | Acta Geologica Sinica(English Edition)2015,89,2: | 9 |
| 10 | Late Paleozoic reefs and their significance for tectonics and oil-gas exploration in the Hinggan-Inner Mongolia area显示文摘Many reefs of the Late Paleozoic have been discovered recently in the Hinggan-Inner Mongolia area.These reefs clearly are geographically extensive,and possess distinctive features and well-developed reef-facies.They have been found to contain five reef-building communities and were constructed in four periods.Colonial coral-algal reefs at Aohan and Chifeng represent a warm shallow-sea in the Carboniferous.Different reefs in the Xiwu Banner were formed in three periods:early Late Carboniferous,late Late Carboniferous and Early Permian.These reefs were built in warm sea conditions.Their buildup types include colonial coral frameworks,algae-buildings and lime-mud mounds.Bryozoan reefs in the Zhalaite and Dongwu banners were built in the late Middle Permian and thrived in a cold shallow-sea.All reefs grew independently on two kinds of sedimentary platforms,carbonate and carbonate-clastic mixed platforms.Four reef-forming periods occurred later from south to north,along a collisional course between the North China Plate and the Siberian Plate.These reefs can be arranged into three 'reef-links' or reef zones that extend along plate margins.Among these,the Aohan-Chifeng reef-link indicates a northern margin of the North China Plate,the Zhalaite-Dongwu reef-link marks a southern margin of the Siberian Plate,and the Xiwu-Beishan reef-link reflects the former existence of some inter-plates.The strata of each reef-facies are thick and contain rich asphalt deposits.Overlapping and heteropic layers are very thick and contain dark oil/gas-rich horizons;TOC analyses verify that most of these are good hydrocarbon source rocks.This study shows that the study area is an excellent candidate for oil-gas exploration. | TIAN ShuGang ZHANG YongSheng WANG JunTao NIU ShaoWu | 2011 | Science China Earth Sciences2011,54,2: | 8 |
| 11 | Effect of particle gradation of aluminum on the explosion field pressure and temperature of RDX-based explosives in vacuum and air atmosphere显示文摘To optimize the energy output and improve the energy utilization efficiency of an aluminized explosive,an explosion device was developed and used to investigate the detonation pressure and temperature of R1(A16)aluminum powder and the aluminum powder particle gradation of R2(Al6+Al13),R3(Al6+Al24)and R4(Al6+AI flake)in a confined space.By using gas chromatography,quantitative analysis and calculations were carried out to analyze the gaseous detonation products.Finally,the reaction ratios of the aluminum powder and the explosion reaction equations were calculated.The results show that in a confined space,the quasi-static pressures and equilibrium temperature of the aluminum powder in air are higher than in vacuum.In vacuum,the quasi-static pressures and equilibrium temperatures of the samples in descending order are R1>R3>R4>R2 and R3>R4>R1>R2,respectively.In air,the quasi-static pressures and equilibrium telperatures of the samples in descending order are R1>R2>R4>R3 and R1>R4>R2>R3,respectively.R4(Al6+AI flake)and R3(Al6+A124)have relatively higher temperatures after detonation,which shows that the particle gradation method can enhance the reaction energy output of aluminum during the initial reaction stage of the explosion and increase the reaction ratio by10.6%and 8.0%,respectively.In air,the reaction ratio of AI6 aluminum powder can reach as high as 78.16%,and the reaction ratio is slightly reduced after particle gradation.Finally,the reaction equations of the explosives in vacuum and in air were calculated by quantitative analysis of the explosion products,which provides a powerful basis for the study of RDX-based explosive reactions. | Fan Jiang Xiao-feng Wang Ya-feng Huang Bo Feng Xuan Tian Yu-lei Niu Kun Zhang | 2019 | Defence Technology(防务技术)2019,15,6: | 8 |
| 12 | Medical services for sports injuries and illnesses in the Beijing 2022 Olympic Winter Games显示文摘BACKGROUND:Beijing 2022 Olympic Winter Games was the second Games held amid the COVID-19 pandemic.To a certain extent,it has altered the way sporting activities operate.There is a lack of knowledge on injury risk and illness occurrence in elite winter sport athletes amid the COVID-19 pandemic.This study aimed to describe the incidence of injuries and illnesses sustained during the XXIV Olympic Winter Games in Beijing from February 4 to 20,2022.METHODS:We recorded the daily number of injuries and illnesses among athletes reported by Beijing 2022 medical staff in the polyclinic,medical venues,and ambulance.We calculated injury and illness incidence as the number of injuries or illnesses occurring during competition or training,respectively,with incidence presented as injuries/illnesses per 100 athlete-days.RESULTS:In total,2,897 athletes from 91 nations experienced injury or illness.Beijing 2022 medical staff reported 326 injuries and 80 illnesses,equaling 11.3 injuries and 2.8 illnesses per 100 athletes over the 17-day period.Altogether,11%of the athletes incurred at least one injury and nearly 3%incurred at least one illness.The number of injured athletes was highest in the skating sports(n=104),followed by alpine skiing(n=53),ice track(n=37),freestyle skiing(n=36),and ice hockey(n=35),and was the lowest in the Nordic skiing disciplines(n=20).Of the 326 injuries,14(4.3%)led to an estimated absence from training or competition of more than 1 week.A total of 52 injured athletes were transferred to hospitals for further care.The number of athletes with illness(n=80)was the highest for skating(n=33)and Nordic skiing(n=22).A total of 50 illnesses(62.5%)were admitted to the department of dentistry/ophthalmology/otolaryngology,and the most common cause of illness was other causes,including preexisting illness and medicine(n=52,65%).CONCLUSION:Overall,11%of athletes incurred at least one injury during the Games,which is similar to the findings during the Olympic Winter Games in 2014 and 2018.Regarding illness,2%of athletes were affected,which is approximately one-third of the number affected in the 2018 Olympic Winter Games. | Peng-da Han Ding Gao Jie Liu Jing Lou Si-jia Tian Hui-xin Lian Sheng-mei Niu Lu-xi Zhang Yong Wang Jin-jun Zhang | 2022 | World Journal of Emergency Medicine2022,13,6: | 7 |

| 14 | Mesenteric lymph reperfusion may exacerbate brain injury in a rat model of superior mesenteric artery occlusion shock显示文摘BACKGROUND:The intestinal lymphatic pathway and intestinal ischemia/reperfusion are mainly involved in mesenteric lymph duct ligation or drainage;moreover,intervention by reducing the lymph liquid reflux might relieve lung and other organ dysfunction induced by intestinal ischemia/reperfusion;however,research addressing mesenteric lymph reperfusion (MLR) and brain injury has not yet to be reported.OBJECTIVE:To observe the effect of MLR on brain tissue in a rat model of superior mesenteric artery occlusion (SMAO) shock,and to explore the molecular mechanism of MLR.DESIGN,TIME AND SETTING:A randomized,controlled,animal experiment at a neuro-pathophysiology level was performed at the Institute of Microcirculation,Hebei North University;Department of Pathophysiology,Basic Medical College;Department of Pathology,the First Hospital of Hebei North University between December 2007 and March 2009.MATERIALS:Adenosine triphosphate (ATP) standard was provided by the National Institute for the Control of Pharmaceutical and Biological Products;lactic acid (LA),superoxide dismutase (SOD),malonaldehyde (MDA),nitrogen monoxidum (NO),nitric oxide synthase (NOS),myeloperoxidase (MPO) and ATPase assay kits were provided by Nanjing Jiancheng Bioengineering Institute,China.METHODS:A total of 24 male Wistar rats were randomly divided into four groups.In the sham-surgery group (n=6),both the mesenteric lymph duct and the superior mesenteric artery were not blocked;in the MLR group (n=6),the mesenteric lymph duct was occluded for 1 hour followed by 2-hour reperfusion;in the SMAO group (n=6),the superior mesenteric artery was occluded for 1 hour followed by 2-hour reperfusion;in the MLR + SMAO group (n=6),both the mesenteric lymph duct and superior mesenteric artery were occluded for 1 hour followed by 2-hour reperfusion.MAIN OUTCOME MEASURES:Mean arterial blood pressure prior to and following ischemia/reperfusion;brain tissue morphology levels of LA,MDA,SOD,NO,NOS,MPO,ATPase and ATP following reperfusion.RESULTS:MLR did not cause changes in mean arterial blood pressure,brain tissue morphology,LA,MDA,NO,ATP,SOD,NOS,MPO and ATPase.However,SMAO caused a rapid decrease and gradual increase of mean arterial blood pressure.Neuronal necrosis,degeneration and swelling were observed in brain tissue.Contents of MDA,NO,LA and ATP as well as activities of NOS and MPO were significantly increased (P < 0.05),but activities of SOD and Na+-K+-ATPase were significantly decreased (P < 0.05).MLR aggravated neuronal damage in a rat model of SMAO shock.Following MLR,mean arterial blood pressure was significantly decreased (P < 0.05),contents of MDA and NO as well as activities of NOS and MPO were significantly increased (P < 0.05),but activities of Ca2+-ATPase,Mg2+-ATPase and Ca2+-Mg2+-ATPase as well as ATP content were significantly decreased (P < 0.05).CONCLUSION:MLR aggravates brain injury in a rat model of SMAO shock,which correlates with oxygen-derived free radical injury,NO synthesis and release,sequestration of neutrophilic granulocytes,decreasing activity of cell membrane pumps and energy metabolism dysfunction.Pathogenesis of the intestinal lymphatic pathway should be thoroughly investigated to prevent ischemia/reperfusion injury. | Zigang Zhao Chunyu Niu Aimin Shang Jiaming Tian Rui Han Chunhui Zhang Yuping Zhang Jing Zhang | 2010 | Neural Regeneration Research2010,5,9: | 7 |

| 16 | Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait. | Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling | 2022 | Molecular Plant2022,15,9: | 6 |
| 17 | Excessive gestational weight gain in early pregnancy and insufficient gestational weight gain in middle pregnancy increased risk of gestational diabetes mellitus显示文摘Background:Gestational weight gain(GWG)is associated with the risk of gestational diabetes mellitus(GDM).However,the effect of weight gain in different trimesters on the risk of GDM is unclear.This study aimed to evaluate the effect of GWG on GDM during different trimesters.Methods:A birth cohort study was conducted from 2017 to 2020 in Shenzhen,China.In total,51,205 participants were included comprising two models(early pregnancy model and middle pregnancy model).Gestational weight(kg)was measured at each prenatal clinical visit using a standardized weight scale.Logistic regression analysis was used to assess the risk of GDM.Interaction analysis and mediation effect analysis were performed in the middle pregnancy model.Results:In the early pregnancy model,the risk of GDM was 0.858 times lower(95%confidence interval[CI]:0.786,0.937)with insufficient GWG(iGWG)and 1.201 times higher(95%CI:1.097,1.316)with excessive GWG after adjustment.In the middle pregnancy model,the risk of GDM associated with iGWG increased 1.595 times(95%CI:1.418,1.794)after adjustment;for excessive GWG,no significant difference was found(P=0.223).Interaction analysis showed no interaction between GWG in early pregnancy(GWG-E)and GWG in middle pregnancy(GWG-M)(F=1.268;P=0.280).The mediation effect analysis indicated that GWG-M plays a partial mediating role,with an effect proportion of 14.9%.Conclusions:eGWG-E and iGWG-M are associated with an increased risk of GDM.Strict control of weight gain in early pregnancy is needed,and sufficient nutrition should be provided in middle pregnancy. | Aiqi Yin Fuying Tian Xiaoxia Wu Yixuan Chen Kan Liu Jianing Tong Xiaonian Guan Huafan Zhang Linlin Wu Jianmin Niu | 2022 | Chinese Medical Journal2022,,9: | 5 |
| 18 | A transceptor-channel complex couples nitrate sensing to calcium signaling in Ambidopsis显示文摘Nitrate-induced Ca^(2+) signaling is crucial for the primary nitrate response in plants.However,the molecular mechanism underlying the generation of the nitrate-specific calcium signature remains unknown.We report here that a cyclic nucleotide-gated channel(CNGC)protein,CNGC15,and the nitrate transceptor(NRT1.1)constitute a molecular switch that controls calcium influx depending on nitrate levels.The expression of CNGC15 is induced by nitrate,and its protein is localized at the plasma membrane after establishment of young seedlings.We found that disruption of CNGC15 results in the loss of the nitrate-induced Ca^(2+) signature(primary nitrate response)and retards root growth,reminiscent of the phenotype observed in the nrt1.1 mutant.We further showed that CNGC15 is an active Ca^(2+)-permeable channel that physically interacts with the NRT1.1 protein in the plasma membrane.Importantly,we discovered that CNGC15-NRT1.1 interaction silences the channel activity of the heterocomplex,which dissociates upon a rise in nitrate levels,leading to reactivation of the CNGC15 channel.The dynamic interactions between CNGC15 and NRT1.1 therefore control the channel activity and Ca^(2+) influx in a nitrate-dependent manner.Our study reveals a new nutrient-sensing mechanism that utilizes a nutrient transceptor-channel complex assembly to couple nutrient status to a specific Ca^(2+) signature. | Xiaohan Wang Changxin Feng LiLi Tian Congcong Hou Wang Tian Bin Hu Qian Zhang Zhijie Ren Qi Niu Jiali Song Dongdong Kong Liangyu Liu Yikun He Ligeng Ma Chengcai Chu Sheng Luan Legong Li | 2021 | Molecular Plant2021,14,5: | 5 |
| 19 | Estimating life-cycle energy payback ratio of overhead transmission line toward low carbon development显示文摘The energy conservation plays an important role for low carbon development.In order to evaluate the energy conservation in the full life-cycle,a scheme to estimate the energy consumption,or alternatively the energy pay,in constructing an overhead transmission line is proposed in this paper.The analysis of a typical projection is given for demonstration.With new additional overhead transmission lines,the energy consumption,known as the power loss in power network,is expected to be decline,which is defined in this paper as the energy payback.In order to estimate this kind of contribution,the scheme that consisted of load forecast,production simulation for generating systems,load flow simulation and power loss calculation has been proposed.Case studies,based on the IEEE 24-bus test system,are given to demonstrate the efficacy of the schemes.Moreover,several presumptive scenarios are deployed and analysed with the presented schemes for comparison. | Xiaoming DONG Chongqing KANG Ning ZHANG Huaguang YAN Junxia MENG Xinsheng NIU Xin TIAN | 2015 | Journal of Modern Power Systems and Clean Energy2015,3,1: | 5 |
| 20 | Clinical observation of laparoscopic cholecystectomy combined with endoscopic retrograde cholangiopancreatography or common bile duct lithotripsy显示文摘BACKGROUND The incidence of common bile duct(CBD) stones accounts for approximately 10%–15% of all CBD diseases.Approximately 8%–20% of these patients also have gallstones with heterogenous signs and symptoms.AIM To investigate the clinical effects of laparoscopic cholecystectomy(LC) combined with endoscopic retrograde cholangiopancreatography(ERCP) and LC with CBD excision and stone extraction in one-stage suture(LBEPS) for the treatment of gallbladder and CBD stones.METHODS Ninety-four patients with gallbladder and CBD stones were selected from our hospital from January 2018 to June 2021.They were randomly divided into study and control groups with 47 patients each.The study group underwent LC with ERCP,and the control group underwent LC with LBEPS.Surgery,recovery time of gastrointestinal function,complication rates,liver function indexes,and stress response indexes were measured pre-and postoperatively in both the groups.RESULTS The durations of treatment and hospital stay were shorter in the study group than in the control group.There was no significant difference between the one-time stone removal rate between the study and control groups.The time to anal evacuation,resumption of oral feeding,time to bowel sound recovery,and time to defecation were shorter in the study group than in the control group.The preoperative serum direct bilirubin(DBIL),total bilirubin(TBIL),and alanine aminotransferase(ALT) levels were insignificantly higher in the study group than that in the control group.A day after surgery,the postoperative serum DBIL,TBIL,and ALT levels were lower than their preoperative levels in both groups,and of the two groups,the levels were lower in the study group.Although the preoperative serum adrenocorticotrophic(ACTH),cortisol(COR),epinephrine(A),and norepinephrine(NE) levels were higher in the study group than that in the control group,these differences were not significant(P > 0.05).The serum ACTH,COR,A,and NE levels in both groups decreased one day after surgery compared to the preoperative levels,but the inter-group difference was statistically insignificant.Similarly,(91.79 ±10.44) ng/mL,A,and NE levels were lower in the study group than in the control group.The incidence of complications was lower in the study group than in the control group.CONCLUSION LC combined with ERCP induces only a mild stress response;this procedure can decrease the risk of complications,improve liver function,and achieve and promote a faster recovery of gastrointestinal functions. | Hong Niu Fei Liu Yi-Bo Tian | 2022 | World Journal of Clinical Cases2022,10,30: | 5 |
