1In situ measurement of PM_1 organic aerosol in Beijing winter using a high-resolution aerosol mass spectrometer显示文摘Organic aerosol (OA) is a crucial component of atmospheric fine particles. To achieve a better understanding of the chemical characteristics and sources of OA in Beijing, the size-resolved chemical composition of submicron aerosols were measured in-situ using a High-Resolution Time-of-Flight Aerosol Mass Spectrometer in the winter of 2010, with a high time resolution of 5 min. During this study, the mean OA mass concentration was 20.9±25.3 μg/m3, varying between 1.9 and 284.6 μg/m3. Elemental analysis showed that the average H/C, O/C and N/C (molar ratio) were 1.70, 0.17, and 0.005, respectively, corresponding to an OM/OC ratio (mass ratio of organic matter to organic carbon) of 1.37. The average mass-based size distributions of OA present a promi- nent accumulation mode peaking at approximately 450 nm. The prominent presence of ultrafine particles (Dva < 100 nm) was mainly from the fresh emissions of combustion sources. A Positive Matrix Factorisation (PMF) analysis of the organic mass spectral dataset differentiated the OA into three components, including hydrocarbon-like (HOA), cooking-related (COA), and oxygenated (OOA) organic aerosols, which, on average, accounted for 26.9%, 49.7% and 23.4%, respectively, of the total organic mass. The HOA and COA likely corresponded to primary organic aerosol (POA) associated with combustion-related and cooking emissions, respectively, and the OOA components corresponded to aged secondary organic aerosol (SOA).LIU Quan SUN Yang HU Bo LIU ZiRui AKIO Shimono WANG YueSi 2012Chinese Science Bulletin2012,57,7:14
2Estimation of aboveground biomass using in situ hyperspectral measurements in five major grassland ecosystems on the Tibetan Plateau显示文摘Aims There are numerous grassland ecosystem types on the Tibetan Plateau.These include the alpine meadow and steppe and degraded alpine meadow and steppe.This study aimed at developing a method to estimate aboveground biomass(AGB)for these grasslands from hyperspectral data and to explore the feasibility of applying air/satellite-borne remote sensing techniques to AGB estimation at larger scales.Methods We carried out a field survey to collect hyperspectral reflectance and AGB for five major grassland ecosystems on the Tibetan Plateau and calculated seven narrow-band vegetation indices and the vegetation index based on universal pattern decomposition(VIUPD)from the spectra to estimate AGB.First,we investigated correlations between AGB and each of these vegetation indices to identify the best estimator of AGB for each ecosystem type.Next,we estimated AGB for the five pooled ecosystem types by developing models containing dummy variables.At last,we compared the predictions of simple regression models and the models containing dummy variables to seek an ecosystem type-independent model to improve prediction of AGB for these various grassland ecosystems from hyperspectral measurements.Important findings When we considered each ecosystem type separately,all eight vegetation indices provided good estimates of AGB,with the best predictor of AGB varying among different ecosystems.When AGB of all the five ecosystems was estimated together using a simple linear model,VIUPD showed the lowest prediction error among the eight vegetation indices.The regression models containing dummy variables predicted AGB with higher accuracy than the simple models,which could be attributed to the dummy variables accounting for the effects of ecosystem type on the relationship between AGB and vegetation index(VI).These results suggest that VIUPD is the best predictor of AGB among simple regression models.Moreover,both VIUPD and the soil-adjusted VI could provide accurate estimates of AGB with dummy variables integrated in regression models.Therefore,ground-based hyperspectral measurements are useful for estimating AGB,which indicates the potential of applying satellite/airborne remote sensing techniques to AGB estimation of these grasslands on the Tibetan Plateau.Miaogen Shen Yanhong Tang Julia Klein Pengcheng Zhang Song Gu Ayako Shimono Jin Chen 2008Journal of Plant Ecology2008,1,4:10

4Patterns of plant diversity at high altitudes on the Qinghai-Tibetan Plateau显示文摘To describe the biodiversity patterns of plants along an altitudinal gradient on the Qinghai-Tibetan Plateau and to clarify the bias in plant specimen records at high altitude.Methods We conducted a large-scale investigation of vegetation at a wide range of altitudes,focusing on a high-altitudinal range(3200-5200 m)at different locations on the Qinghai-Tibetan Plateau.We then compared the altitudinal distribution of plant species obtained from our field investigation with that in plant specimen records from published sources and an online database.Important Findings Our data provide evidence that altitude plays a large role in regulating species composition on the Qinghai-Tibetan Plateau.We could not,however,detect a clear relationship between altitude and species richness,although a weak monotonically increasing trend of richness was detected with increasing altitude.According to specimen records,most species have been sampled at a wide range of altitudes,and the average range of 145 species is>2000 m.Despite this wide range,more than half of the species we observed were at higher altitudes than the specimen records indicate.High-altitude areas have probably been so poorly sampled that only a small fraction of the resident species has been recorded.This study clearly shows the regional bias of specimen records in the Qinghai-Tibetan Plateau.Ayako Shimono Huakun Zhou Haihua Shen Mitsuru Hirota Toshiyuki Ohtsuka Yanhong Tang 2010Journal of Plant Ecology2010,3,1:6
5Complete response to preoperative chemoradiotherapy in highly advanced gastric adenocarcinoma显示文摘This report presents a case of highly advanced gastric cancer that achieved a histologically complete response (CR) to preoperative chemoradiotherapy with S-1 plus low-dose Cisplatin. A 60-year-old male patient underwent FDG positron emission tomography (PET) during a routine health examination. The patient was found to have swollen paraaortic lymph nodes. Shortly thereafter, he was diagnosed with gastric carcinoma with a type 2 tumor in the antrum with paraaortic lymph node metastases based on FDG-PET, endoscopic examination and abdominal computed tomography. After the completion of chemoradiation therapy (CRT), the tumor and the paraaortic lymph node metastases disappeared. The patient underwent surgery 5 wk after the completion of CRT, including a subtotal gastrectomy with Rouxen-Y reconstruction, D3 lymph node dissection and a left adrenalectomy. No cancer cells were detected in the resected specimen either in the primary lesion or lymph nodes, thus confirming a pathologically CR to CRT (CR grade 3). The patient has been stable and well without any evidence of recurrence for 48 mo after surgery. Such a preoperative CRT regimen might therefore be very effective for treatment of some advanced gastric cancers.Hironori Shigeoka Haruhiko Imamoto Yasumasa Nishimura Taro Shimono Hiroshi Furukawa Hiroshi Imamura Takushi Yasuda Hitoshi Shiozaki 2010World Journal of Gastrointestinal Oncology2010,2,6:6
6北京冬季PM_1中有机气溶胶的高分辨率气溶胶质谱观测显示文摘有机气溶胶(OA)是大气细粒子中的重要组分,其化学组成和来源的识别对有效控制颗粒物污染水平具有重要意义.利用高分辨率气溶胶飞行质谱对北京2010年冬季亚微米气溶胶(PM1)中OA质量浓度和粒径分布进行了高时间分辨率(5min)的在线测定,以了解其化学特征及来源.结果表明,北京冬季OA的平均浓度为20.9±25.3ug/m3,最小值与最大值分别为1.9和284.6ug/m3.OA的H/C,O/C,N/C的摩尔比分别为1.70,0.17和0.005,相应的OM/OC(有机物和有机碳的质量比)为1.37.OA的粒径分布范围较宽,在积聚模态450nm附近有明显的峰值,而对超细粒子(Dva<100nm)的贡献主要来自燃烧源的一次排放.北京冬季的OA主要分为3类:烃类有机气溶胶(HOA)、烹饪类有机气溶胶(COA)和氧化性有机气溶胶(OOA),分别占OA的26.9%,49.7%和23.4%.HOA和COA分别来自燃烧源和烹饪源排放的一次有机气溶胶(POA),而OOA则对应着'老化'的二次有机气溶胶(SOA).刘全 孙扬 胡波 刘子锐 AKIO Shimono 王跃思 2012科学通报2012,57,5:6
7Altitudinal variation of ecosystem CO_(2) fluxes in an alpine grassland from 3600 to 4200 m显示文摘Aims Recent studies have recognized the alpine grasslands on the Qinghai-Tibetan plateau as a significant sink for atmospheric CO_(2).The carbon-sink strength may differ among grassland ecosystems at various altitudes because of contrasting biotic and physical environments.This study aims(i)to clarify the altitudinal pattern of ecosystem CO_(2) fluxes,including gross primary production(GPP),daytime ecosystem respiration(Redaytime)and net ecosystem production(NEP),during the period with peak above-ground biomass;and(ii)to elucidate the effects of biotic and abiotic factors on the altitudinal variation of ecosystem CO_(2) fluxes.Methods Ecosystem CO_(2) fluxes and abiotic and biotic environmental factors were measured in an alpine grassland at four altitudes from 3600 to 4200 m along a slope of the Qilian Mountains on the northwestern Qinghai-Tibetan Plateau during the growing season of 2007.We used a closed-chamber method combined with shade screens and an opaque cloth to measure several carbon fluxes,GPP,Redaytime and NEP,and factors,light-response curve for GPP and temperature sensitivity of Redaytime.Above-and below-ground biomasses and soil C and N contents at each measurement point were also measured.Important Findings(i)Altitudinal pattern of ecosystem CO_(2) fluxes:The maximum net ecosystem CO_(2) flux(NEPmax),i.e.the potential ecosystem CO_(2) sink strength,was markedly different among the four altitudes.NEPmax was higher at the highest and lowest sites,ap proximately7.460.9 and6.760.6 lmol CO_(2) m^(-2)s^(-1)(mean 6 standard error),respectively,but smaller at the intermediate altitude sites(3800 and 4000 m).The altitudinal pattern of maximum gross primary production was similar to that of NEPmax.The Redaytime,however,was significantly higher at the lowest altitude(3.460.3 lmol CO_(2) m^(-2)s^(-1))than at the other three altitudes.(ii)Altitudinal variation of vegetation biomass:The aboveground biomass was higher at the highest altitude(154627 g DW m2)than at the other altitudes,which we attribute mainly to the large biomass in cushion plants at the highest altitude.The small above-ground biomass at the lower altitudes was probably due to heavy grazing during the growing season.(iii)Features of ecosystem CO_(2) fluxes:Redaytime and GPP were positively correlated with above-ground biomass.The low ratio of Redaytime to GPP at either the measurement point or the site level suggests that CO_(2) uptake efficiency tends to be higher at higher altitudes,which indicates a high potential sink strength for atmospheric CO_(2) despite the low temperature at high altitudes.The results suggest that the effect of grazing intensity on ecosystem carbon dynamics,partly by decreasing vegetation biomass,should be clarified further.Mitsuru Hirota Pengcheng Zhang Song Gu Mingyuan Du Ayako Shimono Haihua Shen Yingnian Li Yanhong Tang 2009Journal of Plant Ecology2009,2,4:6
8有包含 rituximab 政体的肝炎 B 病毒复活显示文摘 Rituximab is recognized as a useful drug for the treatment of B-cell non-Hodgkin’s lymphoma and its use has been extended to such diseases as idiopathic thrombocytopenic purpura,thrombotic thrombocytopenic purpura,chronic rheumatoid arthritis and ANCA-associated vasculitides.One serious complication associated with its use is the reactivation of hepatitis B virus and the search for methods to prevent this occurrence has resulted in the rapid accumulation of knowledge.In this review,we discuss case analyses from our department and other groups and outline the current knowledge on the topic and the remaining issues.Yutaka Tsutsumi Yoshiya Yamamoto Joji Shimono Hiroyuki Ohhigashi Takanori Teshima 2013World Journal of Hepatology2013,5,11:4
9Case of pediatric traditional serrated adenoma resected via endoscopic submucosal dissection显示文摘Traditional serrated adenoma(TSA)is a type of serrated polyp of the colorectum and is thought to be a precancerous lesion.There are three types of serrated polyps,namely,hyperplastic polyps,sessile serrated adenomas/polyps,and TSAs.TSA is the least common of the three types and accounts for about 5% of serrated polyps.Here we report a pediatric case of TSA that was successfully resected by endoscopic submucosal dissection(ESD).This rare case report describes a pediatric patient with no family history of colonic polyp who was admitted to our hospital with hematochezia.On colonoscopy,we found a polypoid lesion measuring 10 mm in diameter in the lower rectum.We selected ESD as a surgical option for en bloc resection,and histopathological examination revealed TSA.The findings in this case suggest that TSA with precancerous potential can occur in children,and that ESD is useful for treating this lesion.Sonoko Kondo Hirohito Mori Noriko Nishiyama Takeo Kondo Ryuichi Shimono Hitoshi Okada Takashi Kusaka 2017World Journal of Gastroenterology2017,23,24:4
10The role of shrub(Potentilla fruticosa)on ecosystem CO_(2) fluxes in an alpine shrub meadow显示文摘Aims Recent studies have shown that alpine meadows on the Qinghai-Tibetan plateau act as significant CO_(2)sinks.On the plateau,alpine shrub meadow is one of typical grassland ecosystems.The major alpine shrub on the plateau is Potentilla fruticosa L.(Rosaceae),which is distributed widely from 3200 to 4000 m.Shrub species play an important role on carbon sequestration in grassland ecosystems.In addition,alpine shrubs are sensitive to climate change such as global warming.Considering global warming,the biomass and productivity of P.fruticosa will increase on Qinghai-Tibetan Plateau.Thus,understanding the carbon dynamics in alpine shrub meadow and the role of shrubs around the upper distribution limit at present is essential to predict the change in carbon sequestration on the plateau.However,the role of shrubs on the carbon dynamics in alpine shrub meadow remains unclear.The objectives of the present study were to evaluate the magnitude of CO_(2)exchange of P.fruticosa shrub patches around the upper distribution limit and to elucidate the role of P.fruticosa on ecosystem CO_(2)fluxes in an alpine meadow.Methods We used the static acrylic chamber technique to measure and estimate the net ecosystem productivity(NEP),ecosystem respiration(Re),and gross primary productivity(GPP)of P.fruticosa shrub patches at three elevations around the species’upper distribution limit.Ecosystem CO_(2)fluxes and environmental factors were measured from 17 to 20 July 2008 at 3400,3600,and 3800 m a.s.l.We examined the maximum GPP at infinite light(GPPmax)and maximum Re(Remax)during the experimental time at each elevation in relation to aboveground biomass and environmental factors,including air and soil temperature,and soil water content.Important Findings Patches of P.fruticosa around the species’upper distribution limit absorbed CO_(2),at least during the daytime.Maximum NEP at infinite light(NEPmax)and GPPmax of shrub patches in the alpine meadow varied among the three elevations,with the highest values at 3400 m and the lowest at 3800 m.GPPmax was positively correlated with the green biomass of P.fruticosa more strongly than with total green biomass,suggesting that P.fruticosa is the major contributor to CO_(2)uptake in the alpine shrub meadow.Air temperature influenced the potential GPPat the shrub-patch scale.Remax was correlated with aboveground biomass and Remax normalized by aboveground biomass was influenced by soil water content.Potentilla fruticosa height(biomass)and frequency increased clearly as elevation decreased,which promotes the large-scale spatial variation of carbon uptake and the strength of the carbon sink at lower elevations.Yuichiro Yashiro Yoko Shizu Mitsuru Hirota Ayako Shimono Toshiyuki Ohtsuka 2010Journal of Plant Ecology2010,3,2:2

12Phylogeography of Potentilla fruticosa,an alpine shrub on the Qinghai-Tibetan Plateau显示文摘Aims Our objectives were(i)to elucidate the phylogeography of chloroplast DNA(cpDNA)in Potentilla fruticosa in relation to Quaternary climate change and postglacial colonization,(ii)to infer historical population range expansion using mismatch distribution analyses and(iii)to locate the refugia of this alpine species on the Qinghai-Tibetan plateau during glacial-interglacial periods.Methods Potentilla fruticosa is a widespread species distributed on the Qinghai-Tibetan Plateau.We sampled leaves of P.fruticosa from 10 locations along a route of;1300 km from the northeastern plateau(Haibei,Qinghai)to the southern plateau(Dangxiong,Tibet).We examined the cpDNA of 15 haplotypes for 87 individuals from the 10 populations based on the sequence data from;1000 base pairs of the trnS-trnG and rpl20-rps12.Phylogenetic relationship of haplotypes was analyzed using the Phylip software package and the program TCS.The diversity of populations indices was obtained using the program ARLEQUIN.Important Findings With the limited samples,we found that(i)higher nucleotide diversity often occurs in high-altitude populations,(ii)the ancestral haplotypes distribute in the populations with higher nucleotide diversity than recent haplotypes,(iii)the expansion time of population in the high altitudes was estimated to be approximately at 52-25 ka BP(1000 years Before Present,where'Present'is AD 1950)and that in the low altitudes to be;5.1-2.5 ka BPand(iv)the source location of P.fruticosa is at the high altitudes,which might provide refugia for the species during the interglacial warm periods.The species expanded from the high-elevated locations on the Tanggula Mountains during the Holocene.Cui Li Ayako Shimono Haihua Shen Yanhong Tang 2010Journal of Plant Ecology2010,3,1:2
