1Fruit and vegetable consumption,cardiovascular disease,and all-cause mortality in China显示文摘Evidence about the response patterns of fruit and vegetable consumption with the risk of cardiovascular disease(CVD)and allcause mortality was inconsistent.These associations were examined using a large-scale,population-based Chinese cohort comprising 100,728 participants.A food-frequency questionnaire was used to assess fruit and vegetable consumption.Outcomes were ascertained by interviewing individuals or their proxies and checking hospital records or death certificates.Cox proportional hazards regression was used to calculate hazard ratios(HRs)with 95% confidence intervals(CIs).At the 736,668 person-years of follow-up,3,677 CVD cases and 5,466 deaths were identified.The multivariable-adjusted HRs for CVD across increasing quartiles of total fruit and vegetable consumption were 1(reference),0.94(95%CI=0.85-1.04),0.89(95%CI=0.80-0.98),and 0.85(95%CI=0.77-0.95).Moreover,participants in the highest quartile displayed a 13% lower risk of all-cause mortality(HR=0.87;95%CI=0.80-0.95).A nonlinear dose-response relation was found for CVD,without additional benefits beyond a consumption of600 g d-1,whereas the all-cause mortality risk decreased along with higher consumption,with a linear trend.These associations remained significant for fruit consumption but not for vegetable consumption.Our findings indicated that greater fruit and vegetable consumption was significantly associated with a lower risk of CVD and all-cause mortality.Increasing fruit and vegetable consumption,especially fruit,in the general population would prevent CVD and premature mortality.Jun Wang Fangchao Liu Jianxin Li Keyong Huang Xueli Yang Jichun Chen Xiaoqing Liu Jie Cao Shufeng Chen Chong Shen Ling Yu Fanghong Lu Xianping Wu Liancheng Zhao Ying Li Dongsheng Hu Jianfeng Huang Dongfeng Gu Xiangfeng Lu 2022Science China(Life Sciences)2022,65,1:8
2Research of Marine Sensor Web Based on SOA and EDA显示文摘A great deal of ocean sensor observation data exists, for a wide range of marine disciplines, derived from in situ and remote observing platforms, in real-time, near-real-time and delayed mode. Ocean monitoring is routinely completed using sensors and instruments. Standardization is the key requirement for exchanging information about ocean sensors and sensor data and for comparing and combining information from different sensor networks. One or more sensors are often physically integrated into a single ocean ‘instrument' device, which often brings in many challenges related to diverse sensor data formats, parameters units, different spatiotemporal resolution, application domains, data quality and sensors protocols. To face these challenges requires the standardization efforts aiming at facilitating the so-called Sensor Web, which making it easy to provide public access to sensor data and metadata information. In this paper, a Marine Sensor Web, based on SOA and EDA and integrating the MBARI's PUCK protocol, IEEE 1451 and OGC SWE 2.0, is illustrated with a five-layer architecture. The Web Service layer and Event Process layer are illustrated in detail with an actual example. The demo study has demonstrated that a standard-based system can be built to access sensors and marine instruments distributed globally using common Web browsers for monitoring the environment and oceanic conditions besides marine sensor data on the Web, this framework of Marine Sensor Web can also play an important role in many other domains' information integration.JIANG Yongguo DOU Jinfeng GUO Zhongwen HU Keyong 2015Journal of Ocean University of China2015,14,2:2
3Kinetics and mechanism of thermal degradation of vegetable-tanned leather fiber显示文摘Thermal degradation of vegetable-tanned leather fiber(VLF)was investigated by thermogravimetric analysis aiming to know the exact kinetics and degradation mechanism.The thermogravimetric(TG)and differential thermogravimetric(DTG)curves showed that decomposition of the VLF occurs mainly in the range of 150-600℃,and the latter exhibits asymmetrical peak with a pronounced shoulder.The decomposition process was first analyzed by deconvolution of the experimental DTG curves,followed by reconstruction of the weight loss profiles of two individual processes.Several common isoconversional approaches were applied to calculate the activation energy over a wide range of conversion for the sample,including modified Kissinger-Akahira-Sunose(MKAS),Friedman,and Flynn-Wall-Ozawa.The average activation energy of vegetable-tanned leather fiber was found to be 241.9 kJ mol^(−1) by MKAS method.The activation energy values obtained for the pseudocomponents representing highly-crosslinked and low-crosslinked collagen in VLF were given as 190.6 and 124.8 kJ mol^(−1),respectively.Generalized master plots results suggested that the reaction mechanism for highly-crosslinked collagen follows the random nucleation and growth process at conversion values lower than 0.5.When the conversion is higher than 0.5,the mechanism tends to random scission model.For low-crosslinked collagen,the degradation is mainly governed by random nucleation and nuclei growth.The gaseous products of VLF thermal degradation were analyzed with an online-coupled TG-Fourier transform infrared spectroscopy system.Jie Liu Lan Luo Yadi Hu Fang Wang Xuejing Zheng Keyong Tang 2019Journal of Leather Science and Engineering2019,1,1:2
4Adverse associations of sedentary behavior with cancer incidence and all-cause mortality:A prospective cohort study显示文摘Background:Inconsistent results have been reported in developed countries for relationships between sedentary behavior and cancer incidence and mortality,and evidence from the Chinese population is scarce.This study aimed to investigate such relationships in large Chinese population-based prospective cohorts and to explore the joint effect and interaction of sedentary behavior and moderate-to-vigorous physical activity(MVPA)on these relationships.Methods:We included 95,319 Chinese adults without cancer from 3 large cohorts and assessed their sedentary behavior and physical activity with a unified questionnaire.Cancer incidence and mortality were confirmed by interviewing participants or their proxies and checking hospital records and death certificates.Hazard ratios(HRs)and 95%confidence intervals(95%CIs)for cancer and mortality were estimated using Cox proportional hazards regression models.Results:During 559,002 person-years of follow-up,2388 cancer events,1571 cancer deaths,and 4562 all-cause deaths were recorded.Sedentary behavior was associated with increased risk of developing cancer and deaths in a doseresponse manner.The multivariable-adjusted HRs(95%CIs)were the following:HR=1.16,95%CI:1.01-1.33;HR=1.24,95%CI:1.04-1.48;and HR=1.15,95%CI:1.04-1.28 for cancer incidence,cancer mortality,and all-cause mortality,respectively,for those having≥10 h/day of sedentary time compared with those having<6 h/day of sedentary time.Sedentary populations(≥10 h/day)developed cancer or died 4.09 years and 2.79 years earlier,respectively,at the index age of 50 years.Failure to achieve the recommended level of MVPA may further aggravate the adverse associations,with the highest cancer and mortality risks being observed among participants with both≥10 h/day of sedentary time and<150 min/week of MVPA.Limitations of this study include the fact that physical activity information was obtained via questionnaire instead of objective measurement and that there were insufficient incident cases for the analysis of associations between sedentary behavior and site-specific cancers.Conclusion:Sedentary behavior was associated with an increased risk of cancer and all-cause mortality among Chinese adults,especially for those with≥10 h/day of sedentary time.It is necessary to reduce sedentary time,in addition to increasing MVPA levels,for the prevention of cancer and premature death.Yuan Lin Qiong Liu Fangchao Liu Keyong Huang Jianxin Li Xueli Yang Xinyan Wang Jichun Chen Xiaoqing Liu Jie Cao Chong Shen Ling Yu Fanghong Lu Xianping Wu Liancheng Zhao Ying Li Dongsheng Hu Xiangfeng Lu Jianfeng Huang Dongfeng Gu 2021Journal of Sport and Health Science2021,10,5:2

6Generation of oxygen vacancies in NiFe LDH electrocatalysts by ultrasound for enhancing the activity toward oxygen evolution reaction显示文摘Introduction of vacancies is a promising route to enhance the performance of electrocatalysts by tuning the electronic structure and bonding energy.Here,the influence of ultrasound treatment on the O vacancies formation and interlayer spacing in NiFe layered double hydroxide(LDH)was investigated.It is found that the strong ultrasound treatment results in rich O vacancies on the surface of NiFe LDH,which affect the electrocatalysis performance.Besides,the ultrasound treated NiFe LDH electrocatalysts had a reduced thickness with a hexagonal nanosheet morphology and expanded interlayer distance,which could promote the diffusion of reactant and generated gas.When the obtained defect-rich NiFe LDH electrocatalyst prepared by a 10-min ultrasonic treatment was applied to catalyze oxygen evolution reaction(OER),only 194 mV of overpotential was needed to maintain a current density of 10 mA⋅cm^(-2).Xiumin Li Qianyu Hu Yazhou Xu Xiaoyang Liang Jiawei Feng Kunyan Zhao Guoqing Guan Yongchao Jiang Xiaogang Hao Keyong Tang 2021Carbon Resources Conversion2021,4,1:0
7DPOI: Distributed Software System Development Platform for Ocean Information Service显示文摘Ocean information management is of great importance as it has been employed in many areas of ocean science and technology. However, the developments of Ocean Information Systems(OISs) often suffer from low efficiency because of repetitive work and continuous modifications caused by dynamic requirements. In this paper, the basic requirements of OISs are analyzed first, and then a novel platform DPOI is proposed to improve development efficiency and enhance software quality of OISs by providing off-the-shelf resources. In the platform, the OIS is decomposed hierarchically into a set of modules, which can be reused in different system developments. These modules include the acquisition middleware and data loader that collect data from instruments and files respectively, the database that stores data consistently, the components that support fast application generation, the web services that make the data from distributed sources syntactical by use of predefined schemas and the configuration toolkit that enables software customization. With the assistance of the development platform, the software development needs no programming and the development procedure is thus accelerated greatly. We have applied the development platform in practical developments and evaluated its efficiency in several development practices and different development approaches. The results show that DPOI significantly improves development efficiency and software quality.GUO Zhongwen HU Keyong JIANG Yongguo SUN Zhaosui 2015Journal of Ocean University of China2015,14,1:0
8Long-term exposure to fine particulate matter modifies the association between physical activity and hypertension incidence显示文摘Background:The trade-off between the benefits of regular physical activity(PA)and the potentially detrimental effects of augmented exposure to air pollution in highly polluted regions remains unclear.This study aimed to examine whether ambient fine particulate matter(PM_(2.5))exposure modified the impacts of PA volume and intensity on hypertension risk.Methods:We included 54,797 participants without hypertension at baseline in a nationwide cohort of the Prediction for Atherosclerotic Cardiovascular Disease Risk in China(China-PAR)project.PA volume and intensitywere assessed by questionnaire,and high-resolution(1 km×1 km)PM_(2.5)estimates were generated using a satellite-based model.Results:During 413,516 person-years of follow-up,12,100 incident hypertension cases were identified.PM_(2.5)significantly modified the relationship between PA and hypertension incidence(p_(interaction)<0.001).Increased PA volume was negatively associated with incident hypertension in the low PM_(2.5)stratum(<59.8μg/m^(3),ptrend<0.001),with a hazard ratio of 0.81(95%confidence interval(95%CI):0.74-0.88)when comparing the fourth with the first quartile of PA volume.However,the health benefits were not observed in the high PM_(2.5)stratum(≥59.8μg/m^(3),p_(trend)=0.370).Moreover,compared with light PA intensity,vigorous intensity was related to a 20%(95%CI:9%-29%)decreased risk of hypertension for participants exposed to low PM_(2.5),but a 17%(95%CI:4%-33%)increased risk for those with high PM_(2.5)levels.Conclusion:PA was associated with a reduced risk of hypertension only among participants with low PM_(2.5)exposure.Our findings recommended regular PA to prevent hypertension in less polluted regions and reinforced the importance of air quality improvement.Qiong Liu Keyong Huang Fengchao Liang Xueli Yang Jianxin Li Jichun Chen Xiaoqing Liu Jie Cao Chong Shen Ling Yu Yingxin Zhao Ying Deng Ying Li Dongsheng Hu Xiangfeng Lu Yang Liu Dongfeng Gu Fangchao Liu Jianfeng Huang 2022Journal of Sport and Health Science2022,11,6:0
9A combined kinetic study on the pyrolysis of chrome shavings by thermogravimetry显示文摘Chrome shavings(CS),a kind of solid wastes discharged from tanneries,always pose serious environmental problems due to the presence of chromium.In this work,kinetic study of the pyrolysis of CS was investigated using a thermogravimetric analyzer in nitrogen atmosphere.The results obtained from the thermogravimetric analysis indicated that there are three stages in the temperature range 25 to 600℃.The second stage is the main weight loss stage and it could be mainly attributed to the pyrolysis of collagenous materials.Iso-conversional and generalized master-plots method were first employed to estimate the activation energy value and possible reaction mechanism of CS pyrolysis.The results showed that the pyrolysis process could not be described accurately by single-step reaction due to the heterogeneous nature of CS.Afterwards,the thermogravimetric kinetic of CS pyrolysis was studied using combined kinetic analysis.It was found that three-parallel-reaction model allowed better fitting relevance for CS pyrolysis.This information was important for simulating and predicting the pyrolysis behaviors of CS.Jie Liu Lan Luo Zonghui Zhang Yadi Hu Fang Wang Xiumin Li Keyong Tang 2020Carbon Resources Conversion2020,3,1:0
10Integrating polygenic and clinical risks to improve stroke risk stratification in prospective Chinese cohorts显示文摘The utility of the polygenic risk score(PRS)to identify individuals at higher risk of stroke beyond clinical risk remains unclear,and we clarified this using Chinese population-based prospective cohorts.Cox proportional hazards models were used to estimate the 10-year risk,and Fine and Gray’s models were used for hazard ratios(HRs),their 95%confidence intervals(CIs),and the lifetime risk according to PRS and clinical risk categories.A total of 41,006 individuals aged 30–75 years with a mean follow-up of 9.0 years were included.Comparing the top versus bottom 5%of the PRS,the HR was 3.01(95%CI 2.03–4.45)in the total population,and similar findings were observed within clinical risk strata.Marked gradients in the 10-year and lifetime risk across PRS categories were also found within clinical risk categories.Notably,among individuals with intermediate clinical risk,the 10-year risk for those in the top 5%of the PRS(7.3%,95%CI 7.1%–7.5%)reached the threshold of high clinical risk(≥7.0%)for initiating preventive treatment,and this effect of the PRS on refining risk stratification was evident for ischemic stroke.Even among those in the top 10%and 20%of the PRS,the 10-year risk would also exceed this level when aged≥50 and≥60 years,respectively.Overall,the combination of the PRS with the clinical risk score improved the risk stratification within clinical risk strata and distinguished actual high-risk individuals with intermediate clinical risk.Qingmei Cui Fangchao Liu Jianxin Li Xiaoge Niu Zhongying Liu Chong Shen Dongsheng Hu Keyong Huang Shufeng Chen Jie Cao Xiaoqing Liu Ling Yu Fanghong Lu Xianping Wu Liancheng Zhao Jianfeng Huang Ying Li Zhibin Hu Hongbing Shen Dongfeng Gu Xiangfeng Lu 2023Science China(Life Sciences)2023,66,7:0
11Prevalence of familial hypercholesterolemia and its association with coronary artery disease:A Chinese cohort study显示文摘Background:Familial hypercholesterolemia(FH)is underrecognized,and its association with coronary artery disease(CAD)remains limited,especially in China.We aimed to investigate the prevalence of FH and its relationship with CAD in a large Chinese cohort.Methods:FH was defined using the Make Early Diagnosis to Prevent Early Death(MEDPED)criteria.The crude and age-sex standardized prevalence of FH were calculated based on surveys of the Prediction for Atherosclerotic Cardiovascular Disease Risk in China(China-PAR)project during 2007−2008.The associations of FH with incident CAD and its major subtypes were estimated with the cohort-stratified multivariate Cox proportional hazard models based on the data from the baseline to the last follow-up(2018−2020).Results:Among 98,885 included participants,190 participants were defined as FH.Crude and age−sex standardized prevalence and 95%confidence interval(CI)of FH were 0.19%(0.17%-0.22%)and 0.13%(0.10%-0.16%),respectively.The prevalence varied across age groups and peaked in the group of 60-<70 years(0.28%),and the peak prevalence(0.18%)in males was earlier,yet lower than the peak crude prevalence in females(0.41%).During a mean follow-up of 10.7 years,2493 cases of incident CAD were identified.After multivariate adjustment,FH patients had a 2.03-fold greater risk of developing CAD compared to non-FH participants.Conclusions:The prevalence of FH was estimated to be 0.19%in the participants,and it was associated with an elevated risk of incident CAD.Our study suggests that early screening of FH has certain public health significance for the prevention of CAD.Xiapikatijiang Aihaiti Shufeng Chen Jianxin Li Zhennan Lin Qingmei Cui Xue Xia Fangchao Liu Chong Shen Dongsheng Hu Keyong Huang Yingxin Zhao Fanghong Lu Xiaoqing Liu Jie Cao Ling Yu Ying Li Huan Zhang Zhenyan Fu Liancheng Zhao Jianfeng Huang Dongfeng Gu Xiangfeng Lu 2023Chronic Diseases and Translational Medicine2023,9,2:0
12Longitudinal association of egg consumption habits with blood lipids among Chinese adults: results from the Prediction for Atherosclerotic Cardiovascular Disease Risk in China project显示文摘To the Editor:According to guidelines from western countries as well as China,dietary patterns with low intake of cholesterol have been widely recommended for maintaining ideal lipid levels.As one of the major sources of both high-quality protein and dietary cholesterol,eggs have always been the focus in terms of diet.Although increased lipid levels induced by high egg intake have been revealed by randomized controlled trials(RCTs),they may not be sufficient to reflect the impacts of habitual egg intake due to high doses of egg intake of more than 7 eggs/week or even 14 eggs/week.Further,RCTs typically have shorter intervention periods of about 3 months,which may not observe a stable association due to homeostasis in cholesterol metabolism of human beings.[1,2]Up to now,only three cohorts assessed the associations of egg intake with lipid levels or dyslipidemia,and the findings were still controversial.One recent cohort study has reported the non-significant association between higher egg intake(≥7 vs.1 eggs/week)and lipid profiles.On the other hand,another cohort from Spain found that compared with<1 egg/week,>4 eggs/week had no significant influence on total cholesterol(TC)and triglyceride(TG),but significantly decreased high-density lipoprotein cholesterol(HDL-C)levels.[4]However,none of these cohorts were from developing countries,and the association between moderate egg intake and lipid profiles has not been well illustrated.Egg consumption in China,a representative of developing countries,is relatively higher,and it may be possible to better explore the appropriate range of egg intake.Xinyu Zhang Fangchao Liu Jianxin Li Sihan Huang Xue Xia Keyong Huang Qiong Liu Jichun Chen Xueli Yang Xiaoqing Liu Jie Cao Chong Shen Ling Yu Yingxin Zhao Ying Deng Ying Li Dongsheng Hu Jianfeng Huang Xiangfeng Lu Dongfeng Gu 2022Chinese Medical Journal2022,,6:0
