| 1 | Litterfall production and nutrient return in different-aged Chinese fir(Cunninghamia lanceolata) plantations in South China显示文摘The amounts of litter produced and nutrients returned play a fundamental role in the productivity and biogeochemical and nutrient cycling of forest ecosystems.We monitored annual litterfall production, nutrient return,and monthly dynamics over a one-year period in Chinese fir plantations aged 10, 22, and 34 years. Our objective was to quantify litterfall and nutrient return over a complete harvest rotation of Chinese fir. Annual litterfall production increased with stand age and was recorded as(3,294.6 ± 360.4),(3,733.9 ± 211.2), and(4,876.1 ± 212.8) kg ha-1a-1in stands aged 10, 22 and 34 years, respectively. Total litter production was significantly greater in the stand aged34 years than in the stand aged 10 years(p \ 0.05). With the exception of miscellaneous components, needle litterfall constituted the highest proportion(27.5–43.6 %), followed by branches/twigs(9.5–16.6 %). In all three plantations,annual total nutrient return to soil was in the order of C(1,119.95–2,709.05 kg ha-1a-1) [ N(39.32–62.04 kg ha-1a-1) [ K(15.95–22.44 kg ha-1a-1) [ P(1.30–1.63 kg ha-1a-1). C, N, K and P input to soil was significantly lower in the 10-year-old stand in comparison to the 22- and34-year-old stands(p \ 0.05). Litterfall production and nutrient return(C, N and K) followed similar patterns, and C and N input to soil was significantly related to litterfall production(needle, branch and total litterfall). C, N, P and K input to soil and total litterfall production were mainly driven by needle litterfall. | Lili Zhou Addo-Danso Daniel Shalom Pengfei Wu Shubin Li Yayun Jia Xiangqing Ma | 2015 | Journal of Forestry Research2015，26，1： | 32 |
| 2 | Effect of burden and origin sites of premature ventricular contractions on left ventricular function by 7-day Holter monitor显示文摘Recent studies have shown that premature ventricular contractions(PVCs) could enlarge the heart,but its risk factors are incompletely understood as a single 24-hour recording cannot reflect the true PVC burden due to day-to-day variability.Our purpose was to investigate the effect of burden and origin sites on left ventricular(LV) function in patients with PVCs by 7-day Holter electrocardiography(ECG).From May 2012 to August2013,112 consecutive patients with PVCs were recruited from the authors' affiliated hospital.All patients received2-dimensional transthoracic echocardiography,12-lead routing ECG and 7-days Holter ECG.Serum N-terminal probrain natriuretic peptide(NT-proBNP) levels were measured.A total of 102 participants with PVCs were included in the final analysis.Origin of PVCs from the tricuspid annulus had the highest burden and NT-proBNP level.LV papillary muscle had a higher LV ejection fraction(EF) level and a lower LV end-systolic dimension(ESD) than other PVC foci(P<0.05).The high burden group had a higher LV end-diastolic dimension(EDD) and LVESD but lower LVEF than the other two groups(P<0.05).Female,older age,physical work,and history of PVCs had a significantly positive correlation with symptoms.Male,older age,physical work,and high burden were positive predictors of enlarged LVEDD,LVESD and higher serum NT-proBNP level,but lower LVEF.Seven-day dynamic ECG Holter monitor showed the true PVC burden on patients with PVCs.PVCs with a lower burden or origin from the LV papillary muscle and the fascicle were relatively benign,while PVCs with a higher burden or origin from the tricuspid annulus may lead to cardiac dysfunction. | Wenhua Xu Mingfang Li Minglong Chen Bing Yang Daowu Wang Xiangqing Kong Hongwu Chen Weizhu Ju Kai Gu Kejiang Cao Hailei Liu Qi Jiang Jiaojiao Shi Yan Cui Hong Wang | 2015 | The Journal of Biomedical Research2015，29，6： | 4 |

| 4 | The Distribution of Green Algal Micro-Propagules and Macroalgae at the Early Stage of Green Tide in the Coastal Area of South Jiangsu Province in 2014显示文摘An integrated investigation was carried out during late April to late May of 2014 in the coastal area of South Jiangsu Province to understand the early development of green tide in the Yellow Sea and discover the temporal and spatial distribution of green algal micro-propagules and macroalgae at the early stage of green tide. The results showed that green algal micro-propagules distributed in all stations from late April to late May, and micro-propagules of high density(> 300 ind. L^(-1)) concentrated in the adjacent Porphyra aquaculture area. Floating macroalgae were initially observed in the northern survey areas, and increased gradually. The dominant species was U. prolifera in the floating macroalgae, ranging between 90% and 100%. The seawater surface temperature and salinity in the above mentioned time period were suitable for the growth of macroalgae. This work can help government to strengthen management to reduce the blooms of macroalgae in the coastal area of South Jiangsu Province and also facilitate the decision-making for managers at the early stage of green tide. | LIU Xiangqing WANG Zongling FAN Shiliang ZHANG Xuelei LI Ruixiang LI Yan | 2017 | Journal of Ocean University of China2017，16，1： | 3 |
| 5 | Effects of biochar and litter on carbon and nitrogen mineralization and soil microbial community structure in a China fir plantation显示文摘To investigate the effects of biochar addition(1 or 3%)to the soil of a China fir plantation with or without litter,we conducted a 90-day incubation experiment.We also studied the C and N dynamics and the microbial community structure of the soil.In soil without litter,the application of biochar at a rate of 3%significantly decreased CO2 emissions,while addition of 1%biochar had no effect.Biochar application did not affect the net N mineralization rate but significantly reduced the NH4?concentration after 90 days.In litter-enriched soil,biochar application had no significant effect on total CO2 emissions;however,application of 3%biochar significantly reduced the net N mineralization rate.Biochar application to soil with or without litter immediately reduced the dissolved organic carbon(DOC)concentration independent of the application rate,which was primarily due to sorption of DOC by the biochar.Phospholipid fatty acid analysis demonstrated that both concentrations of added biochar to soil(with or without litter)altered the soil microbial community structure at the end of incubation,although the effect of biochar was not as strong as the effect of time or litter application.The effect of biochar addition alone on microbial community structure was inconsistent over time.Litter added to soil significantly increased fungi and reduced Gram-positive bacteria.In the presence of litter,biochar applied at both 1%and 3%significantly increased(p<0.05)the proportion of actinomycete only at day 90.Our results indicate biochar as a potentially effective measure for C sequestration in the test soil of a China fir plantation,even in the presence of litter. | Ying Li Chuifan Zhou Yunxiao Qiu Mulualem Tigabu Xiangqing Ma | 2019 | Journal of Forestry Research2019，30，5： | 3 |
| 6 | Multi-locus association study of schizophrenia susceptibility genes with a posterior probability method显示文摘Schizophrenia is a serious neuropsychiatric illness affecting about 1% of the world’s population. It is considered a complex inheritance disorder. A number of genes are involved in combination in the etiology of the disorder. Evidence implicates the altered dopaminergic trans- mission in schizophrenia. In the present study, in order to identify susceptibility genes for schizophrenia in dopaminergic metabolism, we analyzed 59 single nucleotide polymorphisms (SNPs) in 24 genes of the dopaminergic pathway among 82 unrelated patients with schizophre- nia and 108 matched normal controls. Considering that traditional single-locus association stud- ies ignore the multigenic nature of complex diseases and do not take into account possible in- teractions between susceptibility genes, we proposed a multi-locus analysis method, using the posterior probability of morbidity as a measure of absolute disease risk for a multi-locus genotype combination, and developed an algorithm based on perturbation and average to detect the sus- ceptibility multi-locus genotype combinations, as well as to repress noise and avoid false positive results at our best. A three-locus SNP genotype combination involved in the interactions of COMT and ALDH3B1 genes was detected to be significantly susceptible to schizophrenia. | SUN Xiangqing 1* , JIA Yanbin 2* , ZHANG Xuegong 1 , XU Qi 2 , SHEN Yan 2 & LI Yanda 1 1.

| 9 | Modification of ZnS∶Mn Phosphors by Sb-Doped SnO2 Coating显示文摘The coating of ZnS∶Mn by Sb-doped SnO2 using an co-precipitation process was reported. ZnS∶Mn phosphor particles were prepared by solid reaction with ZnS and MnCl2·4H2O. Surface modification of the ZnS∶Mn powders was carried out by coating transparent conductive films of Sb-doped tin oxides which were formed by co-precipitation and heat treatment process. Tin tetrachloride and antimony trichloride were used as the precursor materials for the co-precipitation. The influences of coating molar ratio, Sb concentration in the coatings, annealing temperature and time on the resistivity of coated ZnS∶Mn phosphors were investigated. The optimum co-precipitation processing parameters and annealing conditions were determined. The phosphors were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), photoluminescence(PL) observation and conductance measurements. An improvement in phosphors conductivity was observed while the respective photoluminescence intensity is analogous to the as-prepared ZnS∶Mn phosphors. | Li Huaixiang Wang Anhe Zhao Jing Zhou Hongwei Zuo Xiangqing | 2006 | Journal of Rare Earths2006，24，z1： | 1 |
| 10 | The dependence of cumulative ^(238)U(n,f) fission yield on incident-neutron energy显示文摘This work is aim at studying the dependence of fission yields on incident neutron energy, so as to produce evaluated yield sets of the energy dependence. Experimental data at different neutron energies for gas fission products 85m,87,88Kr and 138Xe resulting from the 238U(n, f) reaction are processed using codes AVERAGE for weighed average and ZOTT for simultaneous evaluation. Energy dependence of the cumulative fission product yields on the incident neutron is presented. The evaluated curve of product yield is compared with the results calculated by the TALYS-0.64 code. The present evaluation is consistent with other main libraries in error permission. The fit curve of 87,88Kr can be recommended to predict the unmeasured fission yields. Comparisons of the evaluated energy dependence curves with theoretical calculated results show that the predictions using purely theoretical model for the fission process are not sufficiently accurate and reliable for the calculations of the cumulative fission yields for the 238U(n,f). | ZHENG Na ZHONG Chunlai MA Liyong CHEN Zhongjing LI Xiangqing LIU Tingjin CHEN Jinxiang FAN Tleshuan | 2009 | Nuclear Science and Techniques2009，20，5： | 1 |

| 17 | β-decay studies of the neutron-rich ^(18,21)N isotopes显示文摘The β-decay studies of neutron-rich 18,21N isotopes have been performed using β-n, β-γ, and β-n-γ coincidence methods. The 18,21N ions were produced by the fragmentation of the 22Ne and 26Mg beams, respectively, on a thick beryllium target. The time of flight of the emitted neutrons following the β-decay of 18,21N was measured by a neutron detector system with wide energy detection range and low-energy detection threshold. In addition, several clover germanium detectors were used to detect the β-delayed γ-rays. The half-lives of the β-decays of 18N and 21N were determined to be (619±2) ms and (82.9±7.5) ms, respec tively. Several new β-delayed neutron groups were observed with a total branching ratio of (6.98±1.46)% and (90.5±4.2)% for 18N and 21N, respectively. The level schemes of 18O and 21O were deduced. The experimental Gamow-Teller β-decay strengths of 18N and 21N to these levels were compared with the shell model calculations. | HUA Hui, LI ZhiHuan, YE YanLin, JIANG DongXing, LOU JianLing, LI XiangQing & XU FuRong School of Physics and State Key Laboratory of Nuclear Physics and Technology, Peking University, Beijing 100871, China | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S1： | 1 |

| 20 | Relationship between brachial-ankle pulse wave velocity and metabolic syndrome components in a Chinese population显示文摘The purpose of this study was to assess the relationship between arterial stiffness,as measured by brachial-ankle pulse wave velocity(baPWV),and the presence of the metabolic syndrome(MS)in a Chinese population.A total of 4,445 subjects were enrolled.The prevalence of MS in our study population was 21.7%,17.2%and 25.6%for the general population,males and females,respectively.With adjustments for age,gender,cigarette smoking,heart rate,total cholesterol,low-density lipoprotein(LDL)cholesterol,and the use of anti-hypertensive drug,the stepwise regression analysis showed that baPWV had a significant relationship with components of MS,including systolic blood pressure(P<0.001),diastolic blood pressure(P<0.001),glucose(P<0.001),highdensity lipoprotein(HDL)cholesterol(P=0.04),and triglycerides(P<0.001),but no relationship with waist circumference(P=0.25).With an increase in the number of the MS components,baPWV increased significantly both in women and men.This study indicated that the MS is indeed a risk factor for arterial stiffness.Monitoring of baPWV in patients with MS may help in identifying persons at high risk for cardiovascular disease. | Fang Zhou Haifeng Zhang Wenming Yao Hongbin Mei Dongjie Xu Yanhui Sheng Rong Yang Xiangqing Kong Liansheng Wang Jiangang Zou Zhijian Yang Xinli Li | 2014 | The Journal of Biomedical Research2014，28，4： | 1 |
