| 1 | Liver cancer incidence and mortality in China: Temporal trends and projections to 2030显示文摘Objective: Liver cancer is one of the most common cancers and major cause of cancer deaths in China,which accounts for over 50% of new cases and deaths worldwide.The systematic liver cancer statistics including of projection through 2030 could provide valuable information for prevention and control strategies in China,and experience for other countries.Methods: The burden of liver cancer in China in 2014 was estimated using 339 cancer registries' data selected from Chinese National Cancer Center(NCC).Incident cases of 22 cancer registries were applied for temporal trends from 2000 to 2014.The burden of liver cancer through 2030 was projected using age-period-cohort model.Results: About 364,800 new cases of liver cancer(268,900 males and 95,900 females) occurred in China,and about 318,800 liver cancer deaths(233,500 males and 85,300 females) in 2014.Western regions of China had the highest incidence and mortality rates.Incidence and mortality rates decreased by about 2.3% and 2.6% per year during the period of 2000-2014,respectively,and would decrease by more than 44% between 2014 and 2030 in China.The young generation,particularly for those aged under 40 years,showed a faster down trend.Conclusions: Based on the analysis,incidence and mortality rates of liver cancer are expected to decrease through 2030,but the burden of liver cancer is still serious in China,especially in rural and western areas.Most cases of liver cancer in China can be prevented through vaccination and more prevention efforts should be focused on high risk groups. | Rongshou Zheng Chunfeng Qu Siwei Zhang Hongmei Zeng Kexin Sun Xiuying Gu Changfa Xia Zhixun Yang He Li Wenqiang Wei Wanqing Chen Jie He | 2018 | Chinese Journal of Cancer Research2018,30,6: | 132 |
| 2 | The recommendations of Chinese Parkinson’s disease and movement disorder society consensus on therapeutic management of Parkinson’s disease显示文摘Background:Parkinson’s disease(PD)is a chronic,progressive and debilitating disease,which affects over 2.5 million people in China.PD is characterized clinically by resting tremor,muscular rigidity,bradykinesia and postural instability.As the disease progresses,additional complications can arise such as non-motor and neurobehavioral symptoms.Pharmacological treatment and surgical intervention for PD have been implemented in China.Until 10 years ago,there was lack of standardization for the management of PD in different regions and among different physicians,leading to different treatment levels in different regions and different physicians.Since then,the Chinese Parkinson’s Disease and Movement Disorder Society have published three versions of guidelines for the management of PD in China,in 2006,2009 and 2014,respectively.Correspondingly,the overall level of treatment for PD in China improved.Objectives:To update the treatment guidelines based on current foreign and domestic practice guidelines and clinical evidence,and to improve the treatment options available to physicians in the management of PD.Summary:A variety of treatment recommendations in the treatment guidelines have been proposed,including physical activity and disease-modifying medication,which should be initiated at the early-stage of the disease.The principles of dosage titration should be followed to avoid acute adverse reactions to the drugs,to achieve a satisfactory clinical effect with a low dose and to reduce the incidence of long-term motor complications.Moreover,different treatment strategies should be considered at different stages of the disease.Importantly,treatment guidelines and personalized treatments should be valued equally.A set of treatment recommendations has been developed to assist physicians to improve and optimize clinical outcomes for patients with PD in China. | Shengdi Chen Piu Chan Shenggang Sun Haibo Chen Baorong Zhang Weidong Le Chunfeng Liu Guoguang Peng Beisha Tang Lijuan Wang Yan Cheng Ming Shao Zhenguo Liu Zhenfu Wang Xiaochun Chen Mingwei Wang Xinhua Wan Huifang Shang Yiming Liu Pingyi Xu Jian Wang Tao Feng Xianwen Chen Xingyue Hu Anmu Xie Qin Xiao | 2016 | Translational Neurodegeneration2016,5,1: | 23 |
| 3 | Deep crustal structures of eastern China and adjacent seas revealed by magnetic data显示文摘Through reduction to the North Pole and upward continuation of the total field magnetic anomalies, we analyze magnetic patterns and spatial distributions of different tectonic blocks and crustal faults in eastern China and adjacent seas. Depths to the Curie isotherms are further estimated from radially averaged amplitude spectra of magnetic data reduced to the pole. Data reductions effectively enhance boundaries of regional tectonic belts, such as the Dabie ultra-high metamorphic belt, the Tanlu Fault, and the Diaoyudao Uplift. Curie depths are estimated at between 19.6 and 48.9 km, with a mean of 31.7 km. The Subei Basin and the south Yellow Sea Basin in the lower Yangtze block show relatively deep Curie isotherms, up to about 35 km in depth, whereas in the surrounding areas Curie depths are averaged at about 25 km. This implies that the lower Yangtze Block has experienced a unique tectonic evolution and/or has unique basement lithology and structures. From a regional perspective, sedimentary basins, such as the Subei Basin, the south Yellow Sea Basin, and the East China Sea Basin, normally show deeper Curie isotherms than surrounding uplifts such as the Diaoyudao Uplift and the Zhemin Uplifts. Curie isotherms also upwell significantly in volcanically active areas such as the Ryukyu Arc and the Cheju Island, confirming strong magmatic and geothermal activities at depth. | LI ChunFeng CHEN Bing ZHOU ZuYi | 2009 | Science China Earth Sciences2009,52,7: | 21 |
| 4 | Trend analysis of sediment grain size and sedimentary process in the central South Yellow Sea显示文摘With the method of trend analysis of sediment grain size, the sediment transport trend of the fine-grained sediments area in the central South Yellow Sea was studied. The results demonstrated that there is a sedimentation center around the point of 123.4° E, 35.1°N, and the sediments outside the center are transported to it. The patterns of sediment transportation and deposition in the Yellow Sea should be controlled by cyclonic circulation (including the Yellow Sea Cold Water Mass) and cold water gyre. The study also showed that the method of trend analysis of sediment grain size has prospective utilization in the fine-grained sediment deposited area on large-scale continental shelf. | SHI Xuefa CHEN Chunfeng LIU Yanguang REN Hong WANG Huiyan | 2002 | Chinese Science Bulletin2002,47,14: | 17 |
| 5 | Therapeutic effect in patients with coronary heart disease based on information analysis from Traditional Chinese Medicine four diagnostic methods显示文摘OBJECTIVE:To study information gained by Traditional Chinese Medicine(TCM)four diagnostic methods and characteristics of syndrome development before and after treatment in patients with coronary heart disease,and to probe into assessment indexes of therapeutic effects with distinctive TCM features.METHODS:Information from the four diagnostic methods before and after treatment in 100 patients with coronary heart disease was collected using the TCM interrogation scale,a pulse condition instrument,a tongue-face diagnosis instrument,anda voice diagnosis information collection system.Changes in the four diagnostic method results from before and after treatment were analyzed with frequency analysis and t-test methods.RESULTS:Before treatment,deficiency syndrome complicated with hyperactivity of pathogenic factors was most common.After treatment,deficiency syndrome was most common.This change from complex syndromes to single syndromes indicates disease and syndrome alleviation.Frequencies of symptoms gained by interrogation after treatment for syndrome of deficiency of heart-Qi,syndrome of deficiency of heart-Yin,and turbid phlegm syndrome were all less severe than those before treatment.Parameters of face color,color on all sub-regions of tongue,color of tongue fur,septic and greasy fur,and lip color after treatment all had significant changes.After treatment,part of the voice diagnosis parameters in the deficiency of heart-Yin and turbid phlegm syndromes had significant changes,but no significant changes were found in the deficiency of heart-Qi syndrome.CONCLUSION:Use of the TCM four diagnostic methods can provide an effective basis forTCM syndrome diagnosis,observation of development of state of illness,and evaluation of clinical therapeutic effects. | Yiqin Wang Jin Xu Rui Guo Chaoxia Xu Yiming Hao Chunfeng Chen Yijian Hong Xiangqun Xiao Wenjie Xu Jing Hong Zhao Lei | 2014 | Journal of Traditional Chinese Medicine2014,34,1: | 12 |
| 6 | Precollisional tectonics and terrain amalgamation offshore southern Taiwan:Characterizations from reflection seismic and potential field data显示文摘Sponsored by the Chinese National Fundamental Research and Development Program in 2001,Guang-zhou Marine Geological Survey launched out a long geophysical survey from the northeastern part of the South China Sea (SCS),through the Luzon Arc,to the Huatung Basin and the Gagua Ridge. Based on high-resolution seismic data from this survey,combined with gravimetric and magnetic modeling,a systematic effort is made to the study of the regional geodynamics offshore southern Taiwan. By focusing particularly on precollisional tectonic interactions between adjacent geological units and their tectonic affiliations,this study can help reveal early arc-continent collisional processes that formed the Taiwan orogen. The construction of the Manila accretionary prism and its eastward progressive deformation indicate that the subduction of SCS have experienced multiple phases of increased activity. Active precollisional crustal shortening within the Northern Luzon Trough resulted in tilting of sedimentary layers at angles between 6° and 13°. But the shortening induced by tilting accounts for only a tiny part of regional total crustal compression. The eastern flank of the Luzon Arc appears to be more active than the rest,evidenced by active faulting and folding in the intra-arc basins on the eastern flank. Magnetic modeling/inversion shows that the Luzon Arc may have experienced multiple phases of magmatic activities,causing lateral magnetic inhomogeneity. Bouguer gravity anomalies and gravity modeling indicate that the Huatung Basin has anomalously higher crustal and upper mantle densities than those of SCS and the Luzon Arc. In addition,there is a large bathymetric difference between the Huatung Basin and the northeastern part of SCS basin. These observations argue against early hypothesis that the Huatung Basin and the northeastern part of SCS basin may once have belonged to one single oceanic crust,in part or in whole. The Gagua Ridge,as a sliver of uplifted oceanic crust,may be related to a transient northwestward subduction of the western Philippine plate. All evidences point to the argument that the region offshore southern Taiwan is experiencing multiple terrain amalgamation,which is a classical model for continental growth. | LI ChunFeng ZHOU ZuYi LI JiaBiao CHEN HuanJiang GENG JianHua LI Hui | 2007 | Science China Earth Sciences2007,50,6: | 8 |
| 7 | Synthesis of pennogenin utilizing the intact skeleton of diosgenin显示文摘The first synthesis of pennogenin, an aglycone of bioactive components of Chinese traditional medicine named Chonglou(Paris), starting from diosgenin, has been reported, which displays a new strategy of utilizing the resource compounds. According to this new strategy, the full and rational utilization of the intact skeleton and functional groups of starting material has been realized in the conversion of diosgenin to pennogenin. The key step for synthesis of pen-nogenin is the regioselective transformation of cholest-5-en-16,22-dion-3,26-diol to cholest- 5,16-dien-22-on-3,26-diol, which can be used to synthesize other bioactive steroids such as cephalostatin and OSW-1. | TIAN Weisheng XU Qihai CHEN Ling ZHAO Chunfeng | 2004 | Science China Chemistry2004,47,2: | 7 |
| 8 | No expenditure difference among patients with liver cancer at stageⅠ-ⅣV:Findings from a multicenter cross-sectional study in China显示文摘Objective:The number of liver cancer patients in China accounts for more than half of the world.However,China currently lacks national,multicenter economic burden data,and meanwhile,measuring the differences among different subgroups will be informative to formulate corresponding policies in liver cancer control.Thus,the aim of the study was to measure the economic burden of liver cancer by various subgroups.Methods:A hospital-based,multicenter and cross-sectional survey was conducted during 2012・2014,covering 39 hospitals and 21 project sites in 13 provinces across China.The questionnaire covers clinical information,sociology,expenditure,and related variables.All expenditure data were reported in Chinese Yuan(CNY)using 2014 values.Results:A total of 2,223 liver cancer patients were enrolled,of whom 59.61%were late-stage cases(III-IV),and 53.8%were hepatocellular carcinoma.The average total expenditure per liver cancer patient was estimated as 53,220 CNY,including 48,612 CNY of medical expenditures(91.3%)and 4,608 CNY of non-medical expenditures(8.7%).The average total expenditures in stage I,H,m and stage IV were 52,817 CNY,50,877 CNY,50,678 CNY and 54,089 CNY(P>0.05),respectively.Non-medical expenditures including additional meals,additional nutrition care,transportation,accommodation and hired informal nursing were 1,453 CNY,839 CNY,946 CNY,679 CNY and 200 CNY,respectively.The one-year out-of-pocket expenditure of a newly diagnosed patient was 24,953 CNY,and 77.2%of the patients suffered an unmanageable financial burden.Multivariate analysis showed that overall expenditure differed in almost all subgroups(P<0.05),except for sex,clinical stage,and pathologic type.Conclusions:There was no difference in treatment expenditure for liver cancer patients at different clinical stages,which suggests that maintaining efforts on treatment efficacy improvement is important but not enough.To fiirtherly reduce the overall economic burden from liver cancer,more effort should be given to primary and secondary prevention strategies. | Haike Lei Lin Lei Jufang Shi Yongzhong Wu Ling Liang Huiyao Huang Mei He Fangzhou Bai Maomao Cao Hui Qiu Yuting Wang Chengcheng Liu Jia Du Hong Wang Yan Zhang Mengdi Cao Ji Peng Ni Li Chunfeng Qu Min Dai Wanqing Chen Jie He | 2020 | Chinese Journal of Cancer Research2020,32,4: | 7 |
| 9 | Engineering an enthesis-like graft for rotator cuff repair:An approach to fabricate highly biomimetic scaffold capable of zone-specifically releasing stem cell differentiation inducers显示文摘Rotator cuff(RC)attaches to humerus across a triphasic yet continuous tissue zones(bone-fibrocartilage-tendon),termed“enthesis”.Regrettably,rapid and functional enthesis regeneration is challenging after RC tear.The existing grafts bioengineered for RC repair are insufficient,as they were engineered by a scaffold that did not mimic normal enthesis in morphology,composition,and tensile property,meanwhile cannot simultaneously stimulate the formation of bone-fibrocartilage-tendon tissues.Herein,an optimized decellularization approach based on a vacuum aspiration device(VAD)was developed to fabricate a book-shaped decellularized enthesis matrix(O-BDEM).Then,three recombinant growth factors(CBP-GFs)capable of binding collagen were synthesized by fusing a collagen-binding peptide(CBP)into the N-terminal of BMP-2,TGF-β3,or GDF-7,and zone-specifically tethered to the collagen of O-BDEM to fabricate a novel scaffold(CBP-GFs/O-BDEM)satisfying the above-mentioned requirements.After ensuring the low immunogenicity of CBP-GFs/O-BDEM by a novel single-cell mass cytometry in a mouse model,we interleaved urine-derived stem cell-sheets into this CBP-GFs/O-BDEM to bioengineer an enthesis-like graft.Its high-performance on regenerating enthesis was determined in a canine model.These findings indicate this CBP-GFs/O-BDEM may be an excellent scaffold for constructing enthesis-like graft to patch large/massive RC tears,and provide breakthroughs in fabricating graded interfacial tissue. | Can Chen Qiang Shi Muzhi Li Yang Chen Tao Zhang Yan Xu Yunjie Liao Shulin Ding Zhanwen Wang Xing Li Chunfeng Zhao Lunquan Sun Jianzhong Hu Hongbin Lu | 2022 | Bioactive Materials2022,7,10: | 4 |

| 11 | Efficacy and safety of rasagiline in Chinese patients with early Parkinson’s disease:a randomized, double-blind,parallel,placebo-controlled,fixed-dose study显示文摘Background:Rasagiline is a monoamine oxidase-B inhibitor used for Parkinson’s disease(PD)treatment,but its effectiveness on Chinese patients is unclear.This study aimed to evaluate the efficacy and safety of rasagiline monotherapy in Chinese patients with early PD.Methods:A 26-weeks,randomized,double-blind,placebo-controlled study has been performed at 15 sites in China and enrolled outpatients(≥35 years old)with idiopathic PD without a history of using any dopaminergic drugs.Participants were randomized 1:1 to receive rasagiline 1 mg once daily or placebo.The primary endpoint was the change of the Unified Parkinson’s Disease Rating Scale(UPDRS)total score from baseline to 26 weeks treatment.Secondary endpoints included changes in UPDRS subscale scores from part Ⅰ to Ⅲ.Health status was assessed with the PD Questionnaire(PDQ)-39 and EuroQol-Five-Dimension(EQ-5D)questionnaire.Safety profile was collected until 30 weeks after randomization.Results:A total of 130 patients(n=65/group)were recruited,and 127(rasagiline,n=64;placebo,n=63)were included in the full analysis set.Baseline characteristics were comparable between the two groups.The decrease in the mean UPDRS total score was greater in the rasagiline group than in the placebo group(−3.18±0.95 vs.−0.18±0.98,P=0.025),and the mean UPDRS part I non-motor symptoms score(−0.54±0.15 vs.-0.08±0.15,P=0.003)were significantly decreased in the rasagiline group compared with placebo treated patients.An improvement trend was observed in the active treatment group for the subscales evaluation with parts Ⅱ and Ⅲ,while the difference to placebo was not statistically significant.Life quality assessed by the EQ-5D visual analog scale improved in the rasagiline group but worsened in placebo treated patients.The overall incidence of treatment-emergent adverse events(AEs)was slightly lower in the rasagiline group(41.5%)than in the placebo group(46.2%).Conclusions:Rasagiline is effective,safe,and well tolerated as monotherapy for the treatment of Chinese PD patients. | Zhenxin Zhang Jian Wang Shengdi Chen Chunfeng Liu Baorong Zhang Rong Peng Shenggang Sun Xiangru Sun Gang Zhao Qiumin Qu Yansheng Li Suiqiang Zhu Xiaoping Pan Ming Shao Yanping Wang | 2018 | Translational Neurodegeneration2018,7,1: | 3 |
| 12 | A male-ABCD algorithm for hepatocellular carcinoma risk prediction in HBs Ag carriers显示文摘Objective: Hepatocellular carcinoma(HCC) development among hepatitis B surface antigen(HBs Ag) carriers shows gender disparity, influenced by underlying liver diseases that display variations in laboratory tests. We aimed to construct a risk-stratified HCC prediction model for HBs Ag-positive male adults.Methods: HBs Ag-positive males of 35-69 years old(N=6,153) were included from a multi-center populationbased liver cancer screening study. Randomly, three centers were set as training, the other three centers as validation. Within 2 years since initiation, we administrated at least two rounds of HCC screening using Bultrasonography and α-fetoprotein(AFP). We used logistic regression models to determine potential risk factors,built and examined the operating characteristics of a point-based algorithm for HCC risk prediction.Results: With 2 years of follow-up, 302 HCC cases were diagnosed. A male-ABCD algorithm was constructed including participant's age, blood levels of GGT(γ-glutamyl-transpeptidase), counts of platelets, white cells,concentration of DCP(des-γ-carboxy-prothrombin) and AFP, with scores ranging from 0 to 18.3. The area under receiver operating characteristic was 0.91(0.90-0.93), larger than existing models. At 1.5 points of risk score,26.10% of the participants in training cohort and 14.94% in validation cohort were recognized at low risk, with sensitivity of identifying HCC remained 100%. At 2.5 points, 46.51% of the participants in training cohort and 33.68% in validation cohort were recognized at low risk with 99.06% and 97.78% of sensitivity, respectively. At 4.5 points, only 20.86% of participants in training cohort and 23.73% in validation cohort were recognized at high risk,with positive prediction value of 22.85% and 12.35%, respectively.Conclusions: Male-ABCD algorithm identified individual's risk for HCC occurrence within short term for their HCC precision surveillance. | Yuting Wang Minjie Wang He Li Kun Chen Hongmei Zeng Xinyu Bi Zheng Zhu Yuchen Jiao Yong Wang Jian Zhu Hui Zhao Xiang Liu Chunyun Dai Chunsun Fan Can Zhao Deyin Guo Hong Zhao Jianguo Zhou Dongmei Wang Zhiyuan Wu Xinming Zhao Wei Cui Xuehong Zhang Jianqiang Cai Wanqing Chen Chunfeng Qu | 2021 | Chinese Journal of Cancer Research2021,33,3: | 3 |
| 13 | The efficacy and safety of pramipexole ER versus IR in Chinese patients with Parkinson’s disease: a randomized, double-blind, double-dummy, parallel-group study显示文摘Objective:To evaluate the non-inferiority of pramipexole extended-release(ER)versus immediate-release(IR)in Chinese patients with Parkinson’s disease(PD)in a double-blind,randomized,parallel-group study.Methods:Subjects were Chinese patients with idiopathic PD with diagnosis≥2 years prior to trial,age≥30 years old at diagnosis,and Modified Hoehn and Yahr score 2-4 during‘on’-time.Subjects received treatment with pramipexole ER(n=234)or IR(n=239).Non-inferiority was based on the primary endpoint,the change from baseline to end of maintenance(week 18)in the UPDRS(Parts II+III)total score.Results:For the primary endpoint,the adjusted mean changes(standard error)of UPDRS Parts II+III at week 18 were−13.81(0.655)and−13.05(0.643)for ER and IR formulations,respectively,using ANCOVA adjusted for treatment and centre(fixed effect)and baseline(covariate).The adjusted mean between group difference was 0.8 for the 2-sided 95%CI(−1.047,2.566).Since the lower limit of the 2-sided 95%CI(−1.047)for treatment difference was higher than the non-inferiority margin of−4,non-inferiority between pramipexole ER and IR was demonstrated.The incidence of adverse events(AEs)was 68.8%in the ER arm and 73.6%in the IR arm with few severe AEs(ER:2.1%;IR:3.8%).Conclusion:Based on the UPDRS II+III score,pramipexole ER was non-inferior to pramipexole IR.The safety profiles of pramipexole ER and IR were similar.These results were based on comparable mean daily doses and durations of treatment for both formulations. | Ying Wang Shenggang Sun Suiqiang Zhu Chunfeng Liu Yiming Liu Qing Di Huifang Shang Yan Ren Changhong Lu Mark Forrest Gordon Nolwenn Juhel Shengdi Chen for the Pramipexole ER Study Team | 2014 | Translational Neurodegeneration2014,3,1: | 3 |
| 14 | Effects ofβ-alanine on intestinal development and immune performance of weaned piglets显示文摘Beta-alanine is an important amino acid involved in several metabolic reactions in the body.The study aimed to investigate the effect ofβ-alanine supplementation on intestinal development and the immune performance of weaned piglets.Thirty-two 21-day-old healthy weaned piglets(half female and half male;Duroc×Landrace×Yorkshire)with an initial body weight of 8.11±0.21 kg were randomly divided into 4 groups with 8 replicates of 1 pig each.The control group was fed a basal diet and the three experimental treatment groups were fed diets supplemented with 300,600 and 1,200 mg/kgβ-alanine,respectively.The trial lasted 28 days and the diets fed were divided into 2 phases:the late lactation period(day 1 to 14)and the nursery period(day 15 to 28),during which the weaned piglets had free access to food and water.The regulatory effects ofβ-alanine were further investigated in vitro using organoids obtained from the jejunum of piglets.In vivo,the addition ofβ-alanine to the diet had no significant effect on the growth performance of weaned piglets(P>0.05),but significantly reduced serum levels of immunoglobulin G(IgG)(P<0.01),immunoglobulin M(IgM)(P=0.005),and complement 3(C3)(P=0.017).The serum interleukin-6(IL-6)levels(P<0.01)were significantly reduced in the 1,200 mg/kg treatment group.The addition ofβ-alanine increased ileal villus height,with the most significant effect at a concentration of 300 mg/kg(P=0.041).The addition of 600 mg/kgβ-alanine significantly up-regulated the expression of superoxide dismutase(SOD)activity(P=0.020)and the zonula occludens-1(ZO-1)gene(P=0.049)in the jejunum.Diets supplemented with 300 mg/kgβ-alanine significantly increased the number of Ki67 positive cells in the jejunal crypts(P<0.01).In vitro,β-alanine increased the organoid budding rates(P=0.001)and the budding height of the crypt significantly(P=0.004).In conclusion,β-alanine can improve intestinal morphology and barrier function,reduce inflammatory responses and alleviate the adverse effects of weaning stress on piglet intestinal health. | Linlin Chen Yan Zhong Xiangqin Ouyang Chunfeng Wang Lanmei Yin Jing Huang Yali Li Qiye Wang Junyan Xie Pengfei Huang Huansheng Yang Yulong Yin | 2023 | Animal Nutrition2023,,1: | 2 |
| 15 | COMPARING PERFORMANCE OF CROP SPECIES MIXTURES AND PURE STANDS显示文摘Intercropping is the planned cultivation of species mixtures on agricultural land.Intercropping has many attributes that make it attractive for developing a more sustainable agriculture,such as high yield,high resource use efficiency,lower input requirements,natural suppression of pests,pathogens and weeds,and building a soil with more organic carbon and nitrogen.Information is needed which species combinations perform best under different circumstances and which management is suitable to bring out the best from intercropping in a given production situation.The literature is replete with case studies on intercropping from across the globe,but evidence synthesis is needed to make this information accessible.Meta-analysis requires a careful choice of metric that is appropriate for answering the question at hand,and which lends itself for a robust meta-analysis.This paper reviews some metrics that may be used in the quantitative synthesis of literature data on intercropping. | Wopke VAN DER WERF Lizhen ZHANG Chunjie LI Ping CHEN Chen FENG Zhan XU Chaochun ZHANG Chunfeng GU Lammert BASTIAANS David MAKOWSKI TjeerdJan STOMPH | 2021 | Frontiers of Agricultural Science and Engineering2021,8,3: | 2 |

| 17 | Parthenolide attenuates LPS-induced activation of NF-κB in a time-dependent manner in rat myocardium显示文摘Parthenolide(PTN),a selective nuclear factor kappa B(NF-κB)inhibitor,has been used extensively to inhibit NF-κB activation.The duration of the inhibitory effect of PTN on NF-κB in vivo remains unclear.This study was to determine whether a lipopolysaccharide(LPS)challenge 6,12 and 24 h after the administration of PTN could activate NF-κB.Rats were devided into five groups.The rats in the PTN,PTN+LPS and DMSO groups were injected intraperitoneally with PTN or DMSO.After 6,12 or 24 h,LPS was administered in LPS and PTN+LPS groups.The expressions of NF-κB p50,IκBα and p-IκBα were inhibited in both PTN and PTN+LPS group at end of 6 and 12 h and no effects at 24 h.In summary,myocardial NF-κB expression occurs 1 h after the administration of LPS.PTN blocks this effect given at 6 h and no inhibitory effect 24 h after administration in vivo. | Hong Xie Chen Wang Xuemei Wu Xia Liu Shigang Qiao Chunfeng Liu Hong Liu | 2012 | The Journal of Biomedical Research2012,26,1: | 2 |
| 18 | Detecting Non-Stationarity for Auscultation Signal of Traditional Chinese Medicine显示文摘The information about the nonstationarity of the aus-cultation signal is utilized in this paper to objectively and auto-matically identify healthy people and patients with qi-deficiency or yin-deficiency. In order to characterize the nonstationarity of the sound signal,the nonlinear cross-prediction method is used to extract features from the signal. A feature selection method based on conditional mutual information maximization criterion (CMIM) is implemented to find an optimal feature set. By means of the support vector machine (SVM) classifier,three common states (healthy,qi-deficiency and yin-deficiency) in traditional Chinese medicine are distinguished using the feature set,and a satisfactory classification accuracy of 80% is achieved in the experiment. In conclusion,the analysis based on the nonstationarity of the sound signal provides an alternative and outstanding approach to the objective auscultation of traditional Chinese medicine (TCM). | YAN Jianjun SHEN Qingwei WANG Yiqin LI Fufeng GUO Rui CHEN Chunfeng SHEN Yong | 2011 | Wuhan University Journal of Natural Sciences2011,16,1: | 1 |
