| 2 | Kuroshio intrusion into the South China Sea with an anticyclonic eddy: evidence from underwater glider observation显示文摘In this study, high-resolution temperature and salinity data obtained from three Sea-Wing underwater gliders were used together with satellite altimeter data to track the vertical thermohaline structure of an anticyclonic eddy that originated from the loop current of the Kuroshio southwest of Taiwan, China. One of the gliders crossed the entire eddy and it observed a remarkable warm anomaly of as much as 3.9℃ extending to 500 dbar from the base of the mixed layer. Conversely, a positive salinity anomaly was found to be above 200 dbar only in the anticyclonic eddy, with a maximum value of >0.5 in the mixed layer. Below the mixed layer, water of higher salinity (>34.7) was found, which could have been preserved through constrained vertical mixing within the anticyclonic eddy. The salinity in the upper layer of the anticyclonic eddy was much similar to that of the northwestern Pacific Ocean than the northern South China Sea, reflecting Kuroshio intrusion with anticyclonic eddy shedding from the loop current. | LIU Zenghong CHEN Xingrong YU Jiancheng XU Dongfeng SUN Chaohui | 2019 | Journal of Oceanology and Limnology2019，37，5： | 7 |
| 3 | The seasonal variations in the significant wave height and sea surface wind speed of the China's seas显示文摘Long-term variations in a sea surface wind speed(WS) and a significant wave height(SWH) are associated with the global climate change, the prevention and mitigation of natural disasters, and an ocean resource exploitation,and other activities. The seasonal characteristics of the long-term trends in China's seas WS and SWH are determined based on 24 a(1988–2011) cross-calibrated, multi-platform(CCMP) wind data and 24 a hindcast wave data obtained with the WAVEWATCH-III(WW3) wave model forced by CCMP wind data. The results show the following.(1) For the past 24 a, the China's WS and SWH exhibit a significant increasing trend as a whole, of3.38 cm/(s·a) in the WS, 1.3 cm/a in the SWH.(2) As a whole, the increasing trend of the China's seas WS and SWH is strongest in March-April-May(MAM) and December-January-February(DJF), followed by June-July-August(JJA), and smallest in September-October-November(SON).(3) The areal extent of significant increases in the WS was largest in MAM, while the area decreased in JJA and DJF; the smallest area was apparent in SON. In contrast to the WS, almost all of China's seas exhibited a significant increase in SWH in MAM and DJF; the range was slightly smaller in JJA and SON. The WS and SWH in the Bohai Sea, the Yellow Sea, East China Sea, the Tsushima Strait, the Taiwan Strait, the northern South China Sea, the Beibu Gulf, and the Gulf of Thailand exhibited a significant increase in all seasons.(4) The variations in China's seas SWH and WS depended on the season. The areas with a strong increase usually appeared in DJF. | ZHENG Chongwei PAN Jing TAN Yanke GAO Zhansheng RUI Zhenfeng CHEN Chaohui | 2015 | Acta Oceanologica Sinica2015，34，9： | 5 |
| 4 | Materials,preparation,performances and mechanism of polyurethane modified asphalt and its mixture:A systematic review显示文摘With the rapid development of asphalt pavement technology,it has attracted considerable attention to improving the durability of asphalt pavement.An effective action is to use modified asphalt with high performance and durability.Polyurethane(PU)has been used in asphalt pavement engineering to enhance the durability and service life of asphalt pavement because of its excellent high-temperature performance,toughness,wear resistance,aging resistance and oil resistance.However,PU modified asphalt technology is still in the exploratory stage.The preparation,modification mechanism and working performances of PU modified asphalt need to be further clarified.Therefore,this paper summarized the research progress of PU modified asphalt and its mixture.The composition of PU modified asphalt was introduced.The addition methods of PU materials and preparation process parameters of the PU modified asphalt were determined.The modification mechanism of PU on asphalt was discussed.The effects of polyurethane on asphalt were analyzed and the road performances of its mixture were evaluated.Finally,the development tendency towards PU modified asphalt and its mixture were forecasted. | Chaohui Wang Shuai Huang Qian Chen Xiaoping Ji Kaixi Duan | 2023 | Journal of Road Engineering2023，3，1： | 4 |
| 5 | A Numerical Study of Mesoscale Vortex Formation in the Midlatitudes:The Role of Moist Processes显示文摘In this study, a three-dimensional mesoscale model was used to numerically simulate the well-known '98.7' heavy rainfall event that affected the Yangtze Valley in July 1998. Two experiments were conducted to analyze the impact of moist processes on the development of meso-β scale vortices(MβV) and their triggering by mesoscale wind perturbation(MWP). In the experiment in which the latent heat feedback(LHF) scheme was switched off, a stable low-level col field(i.e., saddle field—a region between two lows and two highs in the isobaric surface) formed, and the MWP triggered a weak MβV. However, when the LHF scheme was switched on as the MWP was introduced into the model, the MβV developed quickly and intense rainfall and a mesoscale low-level jet(mLLJ) were generated. The thickness of the air column and average temperature between 400 and 700 hPa decreased without the feedback of latent heat, whereas they increased quickly when the LHF scheme was switched on, with the air pressure falling at low levels but rising at upper levels. A schematic representation of the positive feedbacks among the mesoscale vortex, rainfall, and mLLJ shows that in the initial stage of the MβV, the MWP triggers light rainfall and the latent heat occurs at low levels, which leads to weak convergence and ageostrophic winds. In the mature stage of the MβV, convection extends to the middle-to-upper levels, resulting in an increase in the average temperature and a stretching of the air column. A low-level cyclonic circulation forms under the effect of Coriolis torque, and the m LLJ forms to the southeast of the MβV. | Yongqiang JIANG Yuan WANG Chaohui CHEN Hongrang HE Hong HUANG | 2019 | Advances in Atmospheric Sciences2019，36，1： | 4 |
| 6 | A Convection-Allowing Ensemble Forecast Based on the Breeding Growth Mode and Associated Optimization of Precipitation Forecast显示文摘A convection-allowing ensemble forecast experiment on a squall line was conducted based on the breeding growth mode(BGM). Meanwhile, the probability matched mean(PMM) and neighborhood ensemble probability(NEP)methods were used to optimize the associated precipitation forecast. The ensemble forecast predicted the precipitation tendency accurately, which was closer to the observation than in the control forecast. For heavy rainfall, the precipitation center produced by the ensemble forecast was also better. The Fractions Skill Score(FSS) results indicated that the ensemble mean was skillful in light rainfall, while the PMM produced better probability distribution of precipitation for heavy rainfall. Preliminary results demonstrated that convection-allowing ensemble forecast could improve precipitation forecast skill through providing valuable probability forecasts. It is necessary to employ new methods, such as the PMM and NEP, to generate precipitation probability forecasts. Nonetheless, the lack of spread and the overprediction of precipitation by the ensemble members are still problems that need to be solved. | xiang li hongrang he chaohui chen ziqing miao shigang bai | 2017 | Journal of Meteorological Research2017，31，5： | 4 |
| 7 | Algorithm based on local breeding of growing modes for convection-allowing ensemble forecasting显示文摘We propose a method based on the local breeding of growing modes(LBGM) considering strong local weather characteristics for convection-allowing ensemble forecasting. The impact radius was introduced in the breeding of growing modes to develop the LBGM method. In the local breeding process, the ratio between the root mean square error(RMSE) of local space forecast at each grid point and that of the initial full-field forecast is computed to rescale perturbations. Preliminary evaluations of the method based on a nature run were performed in terms of three aspects: perturbation structure, spread,and the RMSE of the forecast. The experimental results confirm that the local adaptability of perturbation schemes improves after rescaling by the LBGM method. For perturbation physical variables and some near-surface meteorological elements, the LBGM method could increase the spread and reduce the RMSE of forecast,improving the performance of the ensemble forecast system.In addition, different from those existing methods of global orthogonalization approach, this new initial-condition perturbation method takes into full consideration the local characteristics of the convective-scale weather system, thus making convectionallowing ensemble forecast more accurate. | Chaohui CHEN Xiang LI Hongrang HE Jie XIANG Shenjia MA | 2018 | Science China Earth Sciences2018，61，4： | 3 |
| 8 | Textbook Outcome as a measure of surgical quality assessment and prognosis in gastric neuroendocrine carcinoma:A large multicenter sample analysis显示文摘Objective:Quality assurance is crucial for oncological surgical treatment assessment.For rare diseases,singlequality indicators are not enough.We aim to develop a comprehensive and reproducible measurement,called the'Textbook Outcome'(TO),to assess the quality of surgical treatment and prognosis of gastric neuroendocrine carcinoma(G-NEC)patients.Methods:Data from patients with primary diagnosed G-NEC included in 24 high-volume Chinese hospitals from October 2005 to September 2018 were analyzed.TO included receiving a curative resection,≥15 lymph nodes examined,no severe postoperative complications,hospital stay≤21 d,and no hospital readmission≤30 d after discharge.Hospital variation in TO was analyzed using a case mix-adjusted funnel plot.Prognostic factors of survival and risk factors for non-Textbook Outcome(non-TO)were analyzed using Cox and logistic models,respectively.Results:TO was achieved in 56.6%of 860 G-NEC patients.TO patients had better overall survival(OS),disease-free survival(DFS),and recurrence-free survival(RFS)than non-TO patients(P<0.05).Moreover,TO patients accounted for 60.3%of patients without recurrence.Multivariate Cox analysis revealed non-TO as an independent risk factor for OS,DFS,and RFS of G-NEC patients(P<0.05).Increasing TO rates were associated with improved OS for G-NEC patients,but not hospital volume.Multivariate logistic regression revealed that nonlower tumors,open surgery,and>200 mL blood loss were independent risk factors for non-TO patients(P<0.05).Conclusions:TO is strongly associated with multicenter surgical quality and prognosis for G-NEC patients.Factors predicting non-TO are identified,which may help guide strategies to optimize G-NEC outcomes. | Qiyue Chen Zhongliang Ning Zhiyu Liu Yanbing Zhou Qingliang He Yantao Tian Hankun Hao Wei Lin Lixin Jiang Gang Zhao Ping Li Chaohui Zheng Changming Huang on behalf of the Study Group for Gastric Neuroendocrine Tumors | 2021 | Chinese Journal of Cancer Research2021，33，4： | 2 |

| 10 | Efficacy of Chaihu Jisang decoction on post-infection cough and its effect on cough reflex sensitivity显示文摘OBJECTIVE:To investigate the efficacy of Chaihu Ji Sang Decoction(CJSD),(a modification of Xiao Chaihu Tang(Minor Decoction of Bupleurum) was evaluated in patients with post-infection cough(PIC).Its effect on cough reflex sensitivity(CRS) was also described.METHODS:One hundred and eighteen patients with PIC were enrolled and randomly divided into an experimental group and control group(54 patients in each group).The experimental group was given CJSD orally,and the control group was given cetirizine hydrochloride for 7 d.Cough symptom scores and TCM symptom scores were compared before and after treatment.Efficacy,cough onset time,recurrence,and adverse drug reactions were additionally evaluated.Finally,CRS was evaluated before and after treatment of PIC patients in the experimental group.RESULTS:Fifty-two patients in the experimental group and fifty control patients completed the study.Cough symptom scores and the TCM symptom scores of the two groups were significantly improved after treatment,however cough symptoms in the experimental group 1(0,2) were significantly lower than the control group 2(1,2) after treatment(P < 0.05).Similarly,TCM symptom scores 4(0,7) in the experimental group were significantly lower than the control group 6(3,12)(P < 0.01).Overall,the effective rate of the experimental treatment(84.60%) was significantly higher than that of the control treatment(68.00%)(P < 0.01).The onset time of efficacy of the experimental treatment was one day faster than the control treatment [2(2,3) d vs 3(2,3) d,P < 0.01].The relapse rate in the experimental group(9.09%) was lower than that of the control group(29.41%)(P < 0.05).39 PIC patients in the experimental group completed a capsaicin cough challenge test before treatment.The lgC2 and lg C5 of the experimental group prior to treatment was 1.19(0.59,1.49) and 1.80(1.49,2.10),respectively.The lgC2,lg C5 of the healthy control group was 1.49(0.89,2.40) and 2.70(2.40,3.00),respectively.The differences in lgC2 and lg C5 between experimental group and healthy groups were significant at this time point(both P < 0.01).After treatment,34 patients in the experimental group received re-examination.lg C5 increased from 1.80(1.49,2.10) to 2.10(1.49,3.00).CRS after treatment/re-examination was significantly lower than those of baseline in the experimental group(P < 0.05).CONCLUSION:CJSD could effectively improve the clinical symptoms of PIC patients,with demonstrable low recurrence and safety.CJSD also significantly decreased the CRS in patients with PIC. | Hong Minli Huang Baopei Hong Chunlin Chen Huinuan Chen Wenxi Liu Chaohui Li Xinjian Li Candong | 2018 | Journal of Traditional Chinese Medicine2018，38，4： | 2 |
| 11 | Reappraise role of lymph node status in patterns of recurrence following curative resection of gastric adenocarcinoma显示文摘Objective: To examine the association between lymph node status and recurrence patterns in completely resected gastric adenocarcinoma.Methods: We retrospectively assessed 1,694 patients who underwent curative gastrectomy from January 2010 to August 2014. Patients stratified according to lymph node status and recurrence patterns among different subgroups were compared.Results: Of all, 517(30.5%) patients developed recurrent disease, and complete data of recurrence could be obtained in 493(95.4%) patients. For p^(N0) patients, the patterns of recurrence were different according to p T stage: locoregional recurrence was most common in patients with p T1-2 disease(57.1%), distant recurrence was most common in patients with p T3 disease(57.1%), and peritoneal recurrence was most common in patients with p T4 a disease(66.7%). For p^(N+) patients, distant metastasis was most common pattern irrespective of p T stage. The site-specific trend of recurrence showed that locoregional recurrence increased within 5 years in patients with p^(N0)-2 disease but plateaued 3 years after surgery in patients with p N3 disease. Time to recurrence was significantly longer for the p^(N0) patients compared with the p^(N+) patients(median: 25 vs. 16 months, P=0.001).Moreover, post-recurrence survival was significantly better for the p^(N0) patients than for the p^(N+) patients(median:12 vs. 6 months, P<0.001), especially in patients with non-peritoneal recurrence, late recurrence, single recurrence,and receipt of potential curative treatment.Conclusions: Among clinicopathologic factors, lymph node status is the most important factor associated with recurrence patterns after curative gastrectomy. Lymph node status may be used as an adjunct in clinical decisionmaking about postoperative therapeutic and follow-up strategies. | Yihui Tang Jianxian Lin Junpeng Lin Jiabin Wang Jun Lu Qiyue Chen Longlong Caolj Mi Lin Ruhong Tu Changming Huang Ping Li Chaohui Zheng Jianwei Xie | 2021 | Chinese Journal of Cancer Research2021，33，3： | 1 |
| 12 | Neurogranin as an important regulator in swimming training to improve the spatial memory dysfunction of mice with chronic cerebral hypoperfusion显示文摘Background:Vascular cognitive impairment caused by chronic cerebral hypoperfusion(CCH)has become a hot issue worldwide.Aerobic exercise positively contributes to the preservation or restoration of cognitive abilities;however,the specific mechanism has remained inconclusive.And recent studies found that neurogranin(Ng)is a potential biomarker for cognitive impairment.This study aims to investigate the underlying role of Ng in swimming training to improve cognitive impairment.Methods:To test this hypothesis,the clustered regularly interspaced short palindromic repeats(CRISPR)-associated protein 9(Cas9)system was utilized to construct a strain of Ng conditional knockout(Ng cKO)mice,and bilateral common carotid artery stenosis(BCAS)surgery was performed to prepare the model.In Experiment 1,2-month-old male and female transgenic mice were divided into a control group(wild-type littermate,n=9)and a Ng cKO group(n=9).Then,2-month-old male and female C57BL/6 mice were divided into a sham group(C57BL/6,n=12)and a BCAS group(n=12).In Experiment 2,2-month-old male and female mice were divided into a sham group(wild-type littermate,n=12),BCAS group(n=12),swim group(n=12),BCAS+Ng cKO group(n=12),and swim+Ng cKO group(n=12).Then,7 days after BCAS,mice were given swimming training for 5 weeks(1 week for adaptation and 4 weeks for training,5 days a week,60 min a day).After intervention,laser speckle was used to detect cerebral blood perfusion in the mice,and the T maze and Morris water maze were adopted to test their spatial memory.Furthermore,electrophysiology and Western blotting were conducted to record long-term potential and observe the expressions of Ca^(2+)pathway-related proteins,respectively.Immunohistochemistry was applied to analyze the expression of relevant markers in neuronal damage,inflammation,and white matter injury.Results:The figures showed that spatial memory impairment was detected in Ng cKO mice,and a sharp decline of cerebral blood flow and an impairment of progressive spatial memory were observed in BCAS mice.Regular swimming training improved the spatial memory impairment of BCAS mice.This was achieved by preventing long-term potential damage and reversing the decline of Ca^(2+)signal transduction pathway-related proteins.At the same time,the results suggested that swimming also led to improvements in neuronal death,inflammation,and white matter injury induced by CCH.Further study adopted the use of Ng cKO transgenic mice,and the results indicated that the positive effects of swimming training on cognitive impairments,synaptic plasticity,and related pathological changes caused by CCH could be abolished by the knockout of Ng.Conclusion:Swimming training can mediate the expression of Ng to enhance hippocampal synaptic plasticity and improve related pathological changes induced by CCH,thereby ameliorating the spatial memory impairment of vascular cognitive impairment. | Huawei Lin Jiayong Zhang Yaling Dai Huanhuan Liu Xiaojun He Lewen Chen Jing Tao Chaohui Li Weilin Liu | 2023 | Journal of Sport and Health Science2023，12，1： | 1 |

| 15 | Ultrafine tuning of the pore size in zeolite A for efficient propyne removal from propylene显示文摘The removal of trace propyne(C_(3)H_(4))from propyne/propylene(C_(3)H_(4)/C_(3)H_(6))mixtures is a technical and challenging task during the production of polymer-grade propylene in view of their very similar size and physical properties.While some progress has been made,it is still very challenging to use some highly stable and commercially available porous materials via an energy-efficient adsorptive separation process.Herein,we report the ultrafine tuning of the pore apertures in type-A zeolites for the highly efficient removal of trace amounts of C_(3)H_(4)from C_(3)H_(4)/C_(3)H_(6)mixtures.The resulting ion-exchanged zeolite 5 A exhibits a large C_(3)H_(4)adsorption capacity(2.3 mmol g^(-1)under 10^(-4)MPa)and high C_(3)H_(4)/C_(3)H_(6)selectivity at room temperature,which were mainly attributed to the ultrafine-tuned pore size that selectively blocks C_(3)H_(6)molecules,while maintaining the stro ng adsorption of C_(3)H_(4)at low pressure region.High purity of C_(3)H_(6)(>99.9999%)can be directly obtained on this material under ambient conditions,as demonstrated by the experimental breakthrough curves obtained for both 1/99 and 0.1/99.9(V V)C_(3)H_(4)/C_(3)H_(6) mixtures. | Chaohui He Rajamani Krishna Yang Chen Jiangfeng Yang Jinping Li Libo Li | 2021 | Chinese Journal of Chemical Engineering2021，34，9： | 1 |
| 16 | Application of Gaussian Weight to Improve Perturbation Features of Convection-Permitting Ensemble Forecast Based on Local Breeding of Growing Modes显示文摘Local breeding of growing modes(LBGM)is a method used to generate initial condition perturbation(ICP)for convection-permitting ensemble forecasts.Equal weights(EWs)are usually presumed in LBGM during the localization of ICP,without considering different contributions of the grid points within the local radius.To address this problem,Gaussian weights(GWs)are proposed in this study,which can accommodate the varied influences of the grids inside the local radius on the central grid through a Gaussian function.Specifically,two convection-permitting ensemble forecast experiments based on LBGM with GWs and EWs are compared and analyzed respectively for two squall line cases.The results showed that the use of the GWs intensified the local characteristics of the ICP and made the distribution of the ICP fields more flow-dependent.Kinetic energy spectrum of the ICP indicated that there could be more large-scale information in the ICP by using the GWs.In addition,mesoscale information also improved slightly.For forecast of nonprecipitation variables,GWs improved the relationship between the root-mean-square error and the spread and contributed to the forecasting accuracy of wind,temperature,geopotential height,and humidity.For the precipitation forecast,GWs simulated the precipitation structure successfully and provided better probability forecasting during the evolution of the two squall line processes than the EWs. | Kun LI Chaohui CHEN Hongrang HE Ru YANG Yi LI Yongqiang JIANG | 2021 | Journal of Meteorological Research2021，35，3： | 1 |

| 19 | Influence of ENSO Events on Tropical Cyclone Activity over the Western North Pacific显示文摘Based on an analysis of 51-year (1965 2015) data, the influence of El Ni o Southern Oscillation (ENSO) events on tropical cyclone (TC) activity is examined over the western North Pacific (WNP). The total number of TCs formed in the entire WNP reduces by about 3.4 TCs per year in La Ni a years, whereas TCs have an equivalent genesis number between El Ni o years and climatology. During El Ni o years, the frequency of TC formation increases remarkably in the southeast quadrant (140 E 180 , 0 17 N) and decreases in the northwest quadrant (120 140 E, 17 30 N). During La Ni a years, TCs tend to form in the northwest and southwest quadrants (120 140 E, 0 17 N) quadrants. TCs tend to become long-lived in the peak season (from July to Septem- ber) of El Ni o years and during strong El Ni o events. TC genesis shows a southeastward positive shift in terms of lifetime and intensity during El Ni o years, thus more super TCs (winds ≥ 58.64 m s 1) are formed in the southeast quadrant. Further analysis using the genesis potential index (GPI) indicates that the interannual variations in the TC genesis and track are significantly influenced by a combination of large-scale dynamic and thermodynamic conditions. | LIU Zenghong CHEN Xingrong SUN Chaohui CAO Minjie WU Xiaofen LU Shaolei | 2019 | Journal of Ocean University of China2019，18，4： | 1 |
| 20 | Biopolymer passivation for high-performance perovskite solar cells by blade coating显示文摘Thin films of perovskite deposited from solution inevitably introduce large number of defects,which serve as recombination centers and are detrimental for solar cell performance.Although many small molecules and polymers have been delicately designed to migrate defects of perovskite films,exploiting credible passivation agents based on natural materials would offer an alternative approach.Here,an ecofriendly and cost-effective biomaterial,ploy-L-lysine(PLL),is identified to effectively passivate the defects of perovskite films prepared by blade-coating.It is found that incorporation of a small amount(2.5 mg mL^(-1))of PLL significantly boosts the performance of printed devices,yielding a high efficiency of 19.45% with an increase in open-circuit voltage by up to 100 mV.Density functional theory calculations combined with X-ray photoelectron spectroscopy reveal that the functional groups(-NH2,-COOH)of PLL effectively migrate the Pb-I antisite defects via Pb-N coordination and suppress the formation of metallic Pb in the blade-coated perovskite film.This work suggests a viable avenue to exploit passivation agents from natural materials for preparation of high-quality perovskite layers for optoelectronic applications. | Shudi Qiu Xin Xu Linxiang Zeng Zhen Wang Yijun Chen Culling Zhang Chaohui Li Jinlong Hu Tingting Shi Yaohua Mai Fei Guo | 2021 | Journal of Energy Chemistry2021，30，3： | 1 |
