3Failure mechanism and coupled static-dynamic loading theory in deep hard rock mining: A review显示文摘Rock failure phenomena,such as rockburst,slabbing(or spalling) and zonal disintegration,related to deep underground excavation of hard rocks are frequently reported and pose a great threat to deep mining.Currently,the explanation for these failure phenomena using existing dynamic or static rock mechanics theory is not straightforward.In this study,new theory and testing method for deep underground rock mass under coupled static-dynamic loading are introduced.Two types of coupled loading modes,i.e.'critical static stress + slight disturbance' and 'elastic static stress + impact disturbance',are proposed,and associated test devices are developed.Rockburst phenomena of hard rocks under coupled static-dynamic loading are successfully reproduced in the laboratory,and the rockburst mechanism and related criteria are demonstrated.The results of true triaxial unloading compression tests on granite and red sandstone indicate that the unloading can induce slabbing when the confining pressure exceeds a certain threshold,and the slabbing failure strength is lower than the shear failure strength according to the conventional Mohr-Column criterion.Numerical results indicate that the rock unloading failure response under different in situ stresses and unloading rates can be characterized by an equivalent strain energy density.In addition,we present a new microseismic source location method without premeasuring the sound wave velocity in rock mass,which can efficiently and accurately locate the rock failure in hard rock mines.Also,a new idea for deep hard rock mining using a non-explosive continuous mining method is briefly introduced.Xibing Li Fengqiang Gong Ming Tao Longjun Dong Kun Du Chunde Ma Zilong Zhou Tubing Yin 2017Journal of Rock Mechanics and Geotechnical Engineering2017,9,4:68
4Factors predicting occurrence and prognosis of hepatitis-B-virus-related hepatocellular carcinoma显示文摘Primary liver cancer is an important cause of cancer death,and hepatocellular carcinoma(HCC) accounts for 70%-85% of total liver cancer worldwide.Chronic hepatitis B virus(HBV) infection contributes to > 75% of HCC cases.High serum viral load is the most reliable indicator of viral replication in predicting development of HCC.HBV genotype C is closely associated with HCC in cirrhotic patients aged > 50 years,whereas genotype B is associated with development of HCC in non-cirrhotic young patients and postoperative relapse of HCC.Different HBV subgenotypes have distinct patterns of mutations,which are clearly associated with increased risk of HCC.Mutations accumulate during chronic HBV infection and predict occurrence of HCC.Chronic inflammation leads to increased frequency of viral mutation via cellular cytidine deaminase induction.Mutations are negatively selected by host immunity,whereas some immuno-escaped HBV mutants are active in hepatocarcinogenesis.Inflammatory pathways contribute to the inflammation-necrosis-regeneration process,ultimately HCC.Their hallmark molecules can predict malignancy in HBV-infected subjects.Continuing inflammation is involved in hepatocarcinogenesis and closely related to recurrence and metastasis.HBV load,genotype C,viral mutations and expression of inflammatory molecules in HBV-related HCC tissues are significantly associated with poor prognosis.Imbalance between intratumoral CD8+ T cells and regulatory T cells or Th1 and Th2 cytokines in peritumoral tissues can predict prognosis of HBV-related HCC.These factors are important for developing active prevention and surveillance of HBV-infected subjects who are more likely to develop HCC,or for tailoring suitable treatment to improve survival or postpone postoperative recurrence of HCC.Yi-Fang Han Jun Zhao Li-Ye Ma Jian-Hua Yin Wen-Jun Chang Hong-Wei Zhang Guang-Wen Cao 2011World Journal of Gastroenterology2011,17,38:54

6Reservoir-induced landslides and risk control in Three Gorges Project on Yangtze River,China显示文摘The Three Gorges region in China was basically a geohazard-prone area prior to construction of the Three Gorges Reservoir(TGR).After construction of the TGR,the water level was raised from 70 m to 175 m above sea level(ASL).and annual reservoir regulation has caused a 30-m water level difference after impoundment of the TGR since September 2008.This paper first presents the spatiotemporal distribution of landslides in six periods of 175 m ASL trial impoundments from 2008 to 2014.The results show that the number of landslides sharply decreased from 273 at the initial stage to less than ten at the second stage of impoundment.Based on this,the reservoir-induced landslides in the TGR region can be roughly classified into five failure patterns,i.e.accumulation landslide,dip-slope landslide,reversed bedding landslide,rockfall,and karst breccia landslide.The accumulation landslides and dip-slope landslides account for more than 90%.Taking the Shuping accumulation landslide(a sliding mass volume of 20.7 × 10~6 m^3) in Zigui County and the Outang dip-slope landslide(a sliding mass volume of about 90 × 10~6 m^3) in Fengjie County as two typical cases,the mechanisms of reactivation of the two landslides are analyzed.The monitoring data and factor of safety(FOS) calculation show that the accumulation landslide is dominated by water level variation in the reservoir as most part of the mass body is under 175 m ASL,and the dip-slope landslide is controlled by the coupling effect of reservoir water level variation and precipitation as an extensive recharge area of rainfall from the rear and the front mass is below 175 m ASL.The characteristics of landslide-induced impulsive wave hazards after and before reservoir impoundment are studied,and the probability of occurrence of a landslide-induced impulsive wave hazard has increased in the reservoir region.Simulation results of the Ganjingzi landslide in Wushan County indicate the strong relationship between landslide-induced surge and water variation with high potential risk to shipping and residential areas.Regarding reservoir regulation in TGR when using a single index,i.e.1-d water level variation,water resources are not well utilized,and there is also potential risk of disasters since 2008.In addition,various indices such as 1-d.5-d,and 10-d water level variations are proposed for reservoir regulation.Finally,taking reservoir-induced landslides in June2015 for example,the feasibility of the optimizing indices of water level variations is verified.Yueping Yin Bolin Huang Wenpei Wang Yunjie Wei Xiaohan Ma Fei Ma Changjun Zhao 2016Journal of Rock Mechanics and Geotechnical Engineering2016,8,5:45
7Molecular subtyping and genomic profiling expand precision medicine in refractory metastatic triple-negative breast cancer:the FUTURE trial显示文摘Triple-negative breast cancer(TNBC)is a highly heterogeneous disease,and molecular subtyping may result in improved diagnostic precision and targeted therapies.Our previous study classified TNBCs into four subtypes with putative therapeutic targets.Here,we conducted the FUTURE trial(ClinicalTrials.gov identifer:NCT03805399),a phaseⅠb/Ⅱsubtyping-based and genomic biomarker-guided umbrella trial,to evaluate the efficacy of these targets.Patients with refractory metastatic TNBC were enrolled and stratifed by TNBC subtypes and genomic biomarkers,and assigned to one of these seven arms:(A)pyrotinib with capecitabine,(B)androgen receptor inhibitor with CDK4/6 inhibitor,(C)anti PD-1 with nab-paclitaxel,(D)PARP inhibitor included,(E)and(F)anti-VEGFR included,or(G)mTOR inhibitor with nab paclitaxel.The primary end point was the objective response rate(ORR).We enrolled 69 refractory metastatic TNBC patients with a median of three previous lines of therapy(range,1-8).Objective response was achieved in 20(29.0%,95%confidence interval(CI):18.7%-41.2%)of the 69 intention-to-treat(ITT)patients.Our results showed that immunotherapy(arm C),in particular,achieved the highest ORR(52.6%,95%CI:28.9%-75.6%)in the ITT population.Arm E demonstrated favorable ORR(26.1%,95%C:10.2%-48.4%in the ITT population)but with more high grade(23)adverse events.Somatic mutations of TOP2A and CD8 immunohistochemical score may have the potential to predict immunotherapy response in the immunomodulatory subtype of TNBC.In conclusion,the phaseⅠb/ⅡFUTURE trial suggested a new concept for TNBC treatment,demonstrating the clinical beneft of subtyping-based targeted therapy for refractory metastatic TNBC.Yi-Zhou Jiang Yin Liu Yi Xiao Xin Hu Lin Jiang Wen-ia Zuo Ding Ma Jiahan Ding Xiaoyu Zhu Jianjun Zou Claire Verschraegen Daniel G.Stover Virginia Kaklamani Zhong-Hua Wang Zhi-Ming Shao 2021Cell Research2021,31,2:37
8Effects of Subsoiling on Soil Moisture Under No-Tillage for Two Years显示文摘In order to improve the water use efficiency under conservation tillage,the effects of subsoiling on soil moisture under no-tillage were studied. An experiment of 40 cm subsoiling in a field kept under no-tillage for 2 years was operated from 2005 to 2006. Based on the data of the soil moisture and crop yield,the physical basis of subsoiling for water conservation and yield increase was analyzed. The results showed that the soil water storage under subsoiling,from the soil surface to a depth of 100 cm was more than that under no-tillage for the growth season. In the 0-100 cm soil depth,the soil moisture in 50-100 cm depth under subsoiling was more compared with no-tillage,which increased when it's drought and decreased when it's rainy with the increase in soil depth. Compared with no-tillage,subsoiling could reduce the water consumption of oats in the 0-50 cm depth and increase the water consumption in the 50-100 cm depth. Also,subsoiling increased the yield by 18.29% and the water use efficiency by 16.8% in a two-year average. The effects of subsoiling on water conservation and yield increase were affected by precipitation,and a well-proportioned rainfall was better to increase yield and water use efficiency. Meanwhile,subsoiling decreased bulk density,which increased with the available precipitation. Subsoiling under no-tillage is the effective rotation tillage to contain more soil moisture and improve water use efficiency in ecotone of North China.QIN Hong-ling GAO Wang-sheng MA Yue-cun MA Li YIN Chun-mei CHEN Zhe CHEN Chun-lan 2008Agricultural Sciences in China2008,7,1:32

10Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)显示文摘In recent years,as living standards have continued to improve,the number of diabetes patients in China,along with the incidence of complications associated with the disease,has been increasing.Among these complications,diabetic foot disease is one of the main causes of disability and death in diabetic patients.Due to the differences in economy,culture,religion and level of medical care available across different regions,preventive and treatment methods and curative results for diabetic foot vary greatly.In multidisciplinary models built around diabetic foot,the timely assessment and diagnosis of wounds and appropriate methods of prevention and treatment with internal and external surgery are key to clinical practice for this pathology.In 2019,under the leadership of the Jiangsu Medical Association and Chinese Diabetes Society,the writing group for the Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)was established with the participation of scholars from the specialist areas of endocrinology,burn injury,vascular surgery,orthopedics,foot and ankle surgery and cardiology.Drawing lessons from diabetic foot guidelines from other countries,this guide analyses clinical practices for diabetic foot,queries the theoretical basis and grades and gives recommendations based on the characteristics of the pathology in China.This paper begins with assessments and diagnoses of diabetic foot,then describes treatments for diabetic foot in detail,and ends with protections for high-risk feet and the prevention of ulcers.This manuscript covers the disciplines of internal medicine,surgical,nursing and rehabilitation and describes a total of 50 recommendations that we hope will provide procedures and protocols for clinicians dealing with diabetic foot.Aiping Wang Guozhong Lv Xingbo Cheng Xianghua Ma Wei Wang Jianchao Gui JiHu Meng Lu Guoping Chu Jin’an Chen Hao Zhang Yiqiu Jiang Yuedong Chen Wengbo Yang Lin Jiang Houfa Geng Rendong Zheng Yihui Li Wei Feng Boey Johnson Wenjuan Wang Dalong Zhu Yin Hu 2020Burns & Trauma2020,8,1:34
11The combined effects of the ENSO and the Arctic Oscillation on the winter climate anomalies in East Asia显示文摘With the warm/cold phases of the El Ni o and Southern Oscillation (ENSO) as a background, the impacts of monthly variation in the Arctic Oscillation (AO) on the winter climate anomalies in East Asia are studied with the NCEP/DOE Reanalysis 2 data and the Chinese station data regarding temperature and rainfall. The combined effects of ENSO and the AO indicate that the winter climate anomalies are mainly influenced by the AO in northern China and the ENSO in southern China, when an El Ni o couples with a negative AO month or a La Ni a couples with a positive AO month. These climate anomalies in China are consistent with the mechanisms proposed in previous studies. However, most of China presents a different pattern of climate anomalies if an El Ni o couples with a positive AO month or a La Ni a couples with a negative AO month, with the exception of the temperature anomalies in northern China, which are still affected dominantly by the AO. Further analysis suggests that the causes are attributed to the differences in both the stratosphere-troposphere interaction and the extratropics-tropics interaction. In the former cases, zonal symmetric circulation prevails in the winter and the extratropics-tropics interaction is weakened. Thus, the influences of the ENSO and the AO on the East Asian climate mainly present linear combination effects. On the contrary, an annular mode of atmospheric circulation is not favored in the latter cases and the extratropics-tropics interaction is strong. Hence, the combined effects of the ENSO and the AO on the winter climate in East Asia present nonlinear characteristics.CHEN Wen LAN XiaoQing WANG Lin MA Yin 2013Chinese Science Bulletin2013,58,12:30

15Springback equation of small curvature plane bending显示文摘A new analytical method for springback of small curvature plane bending is addressed with unloading rule of classical elastic-plastic theory and principle of strain superposition.We start from strain analysis of plane bending which has initial curvature,and the theoretic derivation is on the widely applicable basic hypotheses.The results are unified to geometry constraint equations and springback equation of plane bending,which can be evolved to straight beam plane bending and pure bending.The expanding and setting round process is one of the situations of plane bending,which is a bend-stretching process of plane curved beam.In the present study,springback equation of plane bending is used to analyze the expanding and setting round process,and the results agree with the experimental data.With a reasonable prediction accuracy,this new analytical method for springback of plane bending can meet the needs of applications in engineering.ZHAO Jun YIN Jing MA Rui MA LiXia 2011Science China(Technological Sciences)2011,54,9:27
16Furazolidone-based triple and quadruple eradication therapy for Helicobacter pylori infection显示文摘AIM: To evaluate the efficacy of furazolidone-based triple and quadruple therapy in eradicating Helicobacter pylori(H. pylori) in a multi-center randomized controlled trial.METHODS: A total of 720 H. pylori positive patients with duodenal ulcer disease were enrolled at 10 different hospitals in Jiangxi province in China. The patients were randomly assigned to four treatment groups as follows: patients in Groups 1 and 3 received rabeprazole(10 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively; patients in Groups 2 and 4 received rabeprazole(10 mg), bismuth(220 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively. The primary outcome measure was H. pylori eradication rate 4 wk after treatment by intention-to-treat and per protocol analysis, while the secondary outcome measures were symptom and sign changes at the end of treatment and 4 wk after the end of treatment, as well as the proportion of patients who developed adverse events.RESULTS: The demographic data of the four groups were not significantly different. Overall, 666 patients completed the scheme and were re-assessed with the 13C-urea breath test. The intention-to-treat analysis of the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 74.44%, 82.78%, 78.89% and 86.11%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. According tothe per protocol analysis, the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 81.21%, 89.22%, 85.54% and 92.26%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. The number of adverse events was 15(8.3%), 16(8.9%), 15(8.3%) and 17(9.4%) in Groups 1, 2, 3 and 4, respectively, including dizziness, vomiting, diarrhea, nausea, skin rash, itchy skin, and malaise. The symptoms were relieved without special treatment in all of the patients.CONCLUSION: Both 7- and 10-d quadruple furazolidone-based therapies achieve satisfactory H. pylori eradication rates.Yong Xie Yin Zhu Hong Zhou Zhi-Fa Lu Zhen Yang Xu Shu Xiao-Bai Guo Hui-Zhen Fan Jian-Hua Tang Xue-Ping Zeng Jian-Bo Wen Xiao-Qing Li Xing-Xing He Jiu-Hong Ma Dong-Sheng Liu Cai-Bin Huang Ning-Jian Xu Nong-Rong Wang Nong-Hua Lu 2014World Journal of Gastroenterology2014,20,32:24
17Climate changes in East China since the Late-glacial inferred from high-resolution mountain peat humification records显示文摘High-resolution peat humification records were obtained from Dajiuhu of the Shennongjia Mountains and Qianmutian of the Tianmu Mountains to study climate changes in East China.The analyses of pollen,organic matters,TOC,and Rb/Sr indicate a high degree of peat humification and thus strong decomposition of organic matter when climate was dry.Conversely,when climate was humid,the degree of humification is low because peat was preserved in a waterlogged condition.Peat humification from Dajiuhu occurred not only during the Younger Dryas(about 11.4-12.6 cal ka BP),the Blling-Allerd Warm Period(12.6-15.2 cal ka BP),and the Oldest Dryas(about 15.2-16.0 cal ka BP),but also during the early Holocene(about 11.4-9.4 cal ka BP),the 8.2 cal ka BP cold event,and the Holocene Optimum(about 7.0-4.2 cal ka BP).Both peat humification records since nearly 5 ka BP are consistent,showing that mountain peatland has synchronous responses to the East Asia monsoon-induced precipitation.The LOI data confirm the above observation.The monsoon precipitation since nearly 5 ka BP recorded in these two peat profiles can be divided into three phases.During 4.9-3.5 ka BP,precipitation amount was high but fluctuated greatly.During 3.5-0.9 ka BP,precipitation amount was low.During 0.9-0 ka BP,degree of humification reduced gradually,indicating the increase of monsoon precipitation.Contrast to other high-resolution records from East China monsoon region shows that the monsoon precipitation records of the two peat profiles since nearly 16 ka BP are controlled by a common forcing mechanism of summer solar radicalization in the Northern Hemisphere.MA ChunMei ZHU Cheng ZHENG ChaoGui YIN Qian ZHAO ZhiPing 2009Science China Earth Sciences2009,52,1:22

19Effects of Rice Straw and Its Biochar Addition on Soil Labile Carbon and Soil Organic Carbon显示文摘Whether the biochar amendment could affect soil organic matter(SOM) turnover and hence soil carbon(C) stock remains poorly understood. Effects of the addition of 13C-labelled rice straw or its pyrolysed biochar at 250 or 350°C to a sugarcane soil(Ferrosol) on soil labile C(di ssolved organic C, DOC; microbial biomass C, MBC; and mineralizable C, MC) and soil organic C(SOC) were investigated after 112 d of laboratory incubation at 25°C. Four treatments were examined as(1) the control soil without amendment(Soil);(2) soil plus 13C-labelled rice straw(Soil+Straw);(3) soil plus 250°C biochar(Soil+B250) and(4) soil plus 350°C biochar(Soil+B350). Compared to un-pyrolysed straw, biochars generally had an increased aryl C, carboxyl C, C and nitrogen concentrations, a decreased O-alkyl C and C:N ratio, but similar alkyl C and ?13C(1 742-1 877 ‰). Among treatments, significant higher DOC, MBC and MC derived from the new C(straw or biochar) ranked as Soil+Straw>Soil+B250>Soil+B350, whilst significant higher SOC from the new C as Soil+B250>Soil+Straw≈Soil+B350. Compared to Soil, DOC and MBC derived from the native soil were decreased under straw or biochar addition, whilst MC from the native soil was increased under straw addition but decreased under biochar addition. Meanwhile, native SOC was similar among the treatments, irrespective of the straw or biochar addition. Compared to Soil, significant higher total DOC and total MBC were under Soil+Straw, but not under Soil+B250 and Soil+B350, whilst significant higher total MC and total SOC were under straw or biochar addition, except for MC under Soil+B350. Our results demonstrated that the application of biochar to soil may be an appropriate management practice for increasing soil C storage.YIN Yun-feng HE Xin-hua GAO Ren MA Hong-liang YANG Yu-sheng 2014Journal of Integrative Agriculture2014,13,3:23
20Differential expression of serum miR-126,miR-141 and miR-21 as novel biomarkers for early detection of liver metastasis in colorectal cancer显示文摘Objective:MicroRNAs(miRNAs) have potential as diagnostic biomarkers in cancer.Evaluation of the association between miRNA expression patterns and early detection of liver metastasis in colorectal cancer(CRC) has not been reported.Methods:We investigated the expression of metastasis-associated miRs-31,335,206,141,126,200b,200c,21,Let7a,Let7b and Let7c in localized,liver-metastatic and other organ-metastatic CRC(OM-CRC).Expressions of target miRNAs in serum were evaluated in 116 consecutive localized CRC(L-CRC),72 synchronous liver-metastatic CRC(SLM-CRC) and 36 other OM-CRC by quantitative real-time PCR.Results:Seven of 11 tested miRNAs could be detected from serum.Four miRNAs,miR-126,Let-7a,miR-141 and miR-21 were identified as metastasis-associated miRNAs.Compared with L-CRC,significant upregulated expression was observed for miR-141 and miR-21 in SLM-CRC and OM-CRC,down-regulated expression was observed for miR-126 in SLM-CRC and OM-CRC,and up-regulated expression of Let-7a in OM-CRC.The receiver operating characteristic(ROC) curve showed serum miR-126 had a cut-off [log 10 relative quantity(log 10 RQ)=–0.2005] with 77.78% sensitivity and 68.97% specificity with an area under curve(AUC) of 0.7564,miR-141 had a cut-off(log 10 RQ=–0.2285) with 86.11% sensitivity and 76.11% specificity with an AUC of 0.8279,and miR-21 had a cut-off(log 10 RQ=–0.1310) with 73.61% sensitivity and 66.38% specificity with an AUC of 0.7479.Conclusions:We identified liver metastasis-associated miRNAs,suggesting serum miR-126,miR-141 and miR-21 may be novel biomarkers for clinical diagnosis of early stage liver-metastatic CRC.Jie Yin Zhigang Bai Jianning Song Yun Yang Jin Wang Wei Han Jun Zhang Hua Meng Xuemei Ma Yao Yang Tingting Wang Weirong Li Zhongtao Zhang 2014Chinese Journal of Cancer Research2014,26,1:22
