Quercus is the largest genus within the Fagaceae and has a rich fossil record.Most of the fossil material is attributed to the subgenus Quercus based on leaves,pollen or rarely acorns and nuts.Fossil records of Q.section Cyclobalanopsis characterized by ring-cupped acorns are relatively few and especially those described based on nuts are scant.In this study,we described four new species of Quercus section Cyclobalanopsis based on mummified acorns and nuts:Q.paleodisciformis X.Y.Liu et J.H.Jin sp.nov.,Q.paleohui X.Y.Liu et J.H.Jin sp.nov.,Q.nanningensis X.Y.Liu et J.H.Jin sp.nov.and Q.yongningensis X.Y.Liu et J.H.Jin sp.nov.These species closely resemble the extant species Q.disciformis,Q.hui,Q.kerrii,and Q.dinghuensis.The occurrence of Q.section Cyclobalanopsis in the Oligocene stratum of Guangxi,South China,suggests that the section has diversified within its extant distribution center since the Oligocene.By combining records from other areas,we propose that the section first appeared in the middle Eocene of East Asia(Sino-Japan),has diversified in situ with a few elements scattering into West Asia and southern Europe since the Oligocene and Pliocene,respectively,and finally became restricted in East Asia since the Pleistocene.This indicates that the section originated and diversified in East Asia,before spreading into West Asia no later than the Oligocene and into southern Europe by the Pliocene.Subsequently it disappeared from South Europe and West Asia due to the appearance of the(summer dry)Mediterranean climate and widespread cooling during the Pleistocene. 展开更多

BACKGROUND Treatment of infantile-onset inflammatory bowel disease(IO-IBD)is often challenging due to its aggressive disease course and failure of standard therapies with a need for biologics.Secondary loss of response is frequently caused by the production of anti-drug antibodies,a well-known problem in IBD patients on biologic treatment.We present a case of IO-IBD treated with therapeutic drug monitoring(TDM)-guided high-dose anti-tumor necrosis factor therapy,in which dose escalation monitoring was used as a strategy to overcome anti-drug antibodies.CASE SUMMARY A 5-mo-old boy presented with a history of persistent hematochezia from the 10th d of life,as well as relapsing perianal abscess and growth failure.Hypoalbuminemia,anemia,and elevated inflammatory markers were also present.Endoscopic assessment revealed skip lesions with deep colic ulcerations,inflammatory anal sub-stenosis,and deep fissures with persistent abscess.A diagnosis of IO-IBD Crohn-like was made.The patient was initially treated with oral steroids and fistulotomy.After the perianal abscess healed,adalimumab(ADA)was administered with concomitant gradual tapering of steroids.Clinical and biochemical steroid-free remission was achieved with good trough levels.After 3 mo,antibodies to ADA(ATA)were found with undetectable trough levels;therefore,we optimized the therapy schedule,first administering 10 mg weekly and subsequently up to 20 mg weekly(2.8 mg/kg/dose).After 2 mo of high-dose treatment,ATA disappeared,with concomitant high trough levels and stable clinical and biochemical remission of the disease.CONCLUSION TDM-guided high-dose ADA treatment as a monotherapy overcame ATA production.This strategy could be a good alternative to combination therapy,especially in very young patients. 展开更多

The same problem of water shortage is one of the hot spots of global concern. The peak-cluster depression basins in southwest of Guangxi is an important water connotation and ecological barrier areas in the Pearl River Basin of China. Thus, studying the spatial and temporal variations and the influencing factors of its water yield services is critical to achieve the sustainable development of water resources and ecological environmental protection in this region. As such, this paper uses the Integrated Valuation of Ecosystem Services and Tradeoffs(InVEST) model to assess the spatial and temporal variabilities of water yield services and its trends in the peak-cluster depression basins in southwest of Guangxi from 2000 to 2020. This work also integrates precipitation(Pre), reference evapotranspiration(ET), temperature(Tem), digital elevation model(DEM), slope, normalized difference vegetation index(NDVI), land use/land cover(LULC) and soil type to reveal the main factors that influence water yield services with the help of Geodetector. Results show that: 1) in time scale,the total annual water yield in the study area show a fluctuating and increasing trend from 2000 to 2020, with a growth rate of 7.3753 × 10^(8)m^(3)/yr, and its multi-year average water yield was 538.07 mm;2) in spatial pattern, with high yield areas mainly distributed in the south of the study area(mainly including Shangsi County, Pingxiang City, Ningming County, Longzhou County and Jingxi County), and low yield areas mainly distributed in Baise City and Nanning City;3) the dominant factor of water yield within karst and non-karst landforms is not necessarily controlled by precipitation, and the explanation degree of DEM factors in karst areas is significantly higher than that in non-karst areas;4) amongst the climatic factors, Pre, ET and Tem are dominant in the spatial pattern of region water yield capacity. among which Pre has the highest explanatory power for the spatial heterogeneity of annual water production, with q values above0.8, and each driver showed a significant interaction on the spatial distribution of water yield, with Pre exhibiting the strongest interaction with LULC. 展开更多

为评估月尺度IMERG(V06)降水产品在广西地区的精度,将广西划为少雨区(年均降水量≤1 300 mm,Ⅰ区)、中雨区(年均降水量>1 300~1 700 mm,Ⅱ区)、多雨区(年均降水量>1 700 mm,Ⅲ区)3个区域,以91个观测站2001—2020年逐月降水量为参... 为评估月尺度IMERG(V06)降水产品在广西地区的精度,将广西划为少雨区(年均降水量≤1 300 mm,Ⅰ区)、中雨区(年均降水量>1 300~1 700 mm,Ⅱ区)、多雨区(年均降水量>1 700 mm,Ⅲ区)3个区域,以91个观测站2001—2020年逐月降水量为参考,采用相关系数(correlation coefficient,CC)、均方根误差(root mean square error,RMSE)和相对偏差(relative error,RE)3个定量指标,从不同空间尺度、时间尺度、降水量区间等维度分析Early、Late、Final系列产品的精度特征。结果发现:1)Early、Late产品精度特征相似,整体上低估降水;而Final产品整体高估降水。2)降水量增加引起各系列产品CC下降、RMSE上升、RE下降;Early、Late、Final产品对月降水量估测的偏差阈值分别为271、272和351 mm,实测月降水量低于该阈值时被高估,反之则被低估。3)IMERG产品在降水量多的区域相关性更强,离散度更高,在Ⅰ、Ⅱ区表现为高估,在Ⅲ区表现为低估。4)产品精度在降水较少的旱季和旱年更高;Early、Late产品在秋季表现相对较好,但有较明显的低估;Final产品在冬季表现最佳。5)年际间,Final产品精度有下降趋势,Early、Late产品估测偏差愈发趋向高估。综上所述,广西地区月尺度IMERG产品精度受降水量影响显著,在不同地区、不同时段存在较大差异,应用时需针对具体区域、时间评估其精度局限性。 展开更多
