| 1 | Identification of plasma microRNA-21 as a biomarker for early detection and chemosensitivity of non-small cell lung cancer显示文摘Studies have shown cell-free microRNA(miRNA) circulating in the serum and plasma with specific expression in cancer,indicating the potential of using miRNAs as biomarkers for cancer diagnosis and therapy.This study was to investigate whether plasma miRNA-21(miR-21) can be used as a biomarker for the early detection of non-small cell lung cancer(NSCLC) and to explore its association with clinicopathologic features and sensitivity to platinum-based chemotherapy.We used real-time RT-PCR to investigate the expression of miR-21 in the plasma of 63 NSCLC patients and 30 healthy controls and correlated the findings with early diagnosis,pathologic parameters,and treatment.Thirty-five patients(stages IIIB and IV) were evaluable for chemotherapeutic responses:11 had partial response(PR);24 had stable and progressive disease(SD+PD).Plasma miR-21 was significantly higher in NSCLC patients than in age-and sex-matched controls(P<0.001).miR-21 was related to TNM stage(P<0.001),but not related to age,sex,smoking status,histological classification,lymph node status,and metastasis(all P>0.05).This marker yielded a receiver operating characteristic(ROC) curve area of 0.775(95% CI:0.681-0.868) with 76.2% sensitivity and 70.0% specificity.Importantly,miR-21 plasma levels in PR samples were several folds lower than that in SD plus PD samples(P=0.049),and were close to that in healthy controls(P=0.130).Plasma miR-21 can serve as a circulating tumor biomarker for the early diagnosis of NSCLC and is related to the sensitivity to platinum-base chemotherapy. | Juan Wei Wen Gao Cheng-Jun Zhu Yi-Qian Liu Zhu Mei Ting Cheng Yong-Qian Shu | 2011 | Chinese Journal of Cancer2011，30，6： | 63 |

| 4 | Report on Childhood Obesity in China (9): Sugar-sweetened Beverages Consumption and Obesity显示文摘Objective To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design. | SHANG Xian Wen LIU Ai Ling ZHANG Qian HU Xiao Qi DU Song Ming MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin LI Ting Yu MA Guan Sheng | 2012 | Biomedical and Environmental Sciences2012，25，2： | 23 |
| 5 | Baicalin induces ferroptosis in bladder cancer cells by downregulating FTH1显示文摘Ferroptosis is a non-apoptotic regulated cell death caused by iron accumulation and subsequent lipid peroxidation.Currently,the therapeutic role of ferroptosis on cancer is gaining increasing interest.Baicalin an active component in Scutellaria baicalensis Georgi with anticancer potential various cancer types;however,the effects of baicalein on bladder cancer and the underlying molecular mechanisms remain largely unknown.In the study,we investigated the effect of baicalin on bladder cancer cells5637 and KU-19-19.As a result,we show baicalin exerted its anticancer activity by inducing apoptosis and cell death in bladder cancer cells.Subsequently,we for the first time demonstrate baicalin-induced ferroptotic cell death in vitro and in vivo,accompanied by reactive oxygen species(ROS) accumulation and intracellular chelate iron enrichment.The ferroptosis inhibitor deferoxamine but not necrostatin-1,chloroquine(CQ),N-acetyl-L-cysteine,L-glutathione reduced,or carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]-fluoromethylketone(Z-VAD-FMK) rescued baicalin-induced cell death,indicating ferroptosis contributed to baicalin-induced cell death.Mechanistically,we show that ferritin heavy chain1(FTH1) was a key determinant for baicalin-induced ferroptosis.Overexpression of FTH1 abrogated the anticancer effects of baicalin in both 5637 and KU19-19 cells.Taken together,our data for the first time suggest that the natural product baicalin exerts its anticancer activity by inducing FTH1-dependent ferroptosis,which will hopefully provide a prospective compound for bladder cancer treatment. | Na Kong Xiaying Chen Jiao Feng Ting Duan Shuiping Liu Xueni Sun Peng Chen Ting Pan Lili Yan Ting Jin Yu Xiang Quan Gao Chengyong Wen Weirui Ma Wencheng Liu Mingming Zhang Zuyi Yang Wengang Wang Ruonan Zhang Bi Chen Tian Xie Xinbing Sui Wei Tao | 2021 | Acta Pharmaceutica Sinica B2021，11，12： | 23 |
| 6 | Effects of ultrahigh pressure extraction on yield and antioxidant activity of chlorogenic acid and cynaroside extracted from flower buds of Lonicera japonica显示文摘The present study was designed to establish and optimize a new method for extracting chlorogenic acid and cynaroside from Lonicera japonica Thunb. through orthogonal experimental designl. A new ultrahigh pressure extraction(UPE) technology was applied to extract chlorogenic acid and cynaroside from L. japonica. The influential factors, including solvent type, ethanol concentration, extraction pressure, time, and temperature, and the solid/liquid ratio, have been studied to optimize the extraction process. The optimal conditions for the UPE were developed by quantitative analysis of the extraction products by HPLC-DAD in comparison with standard samples. In addition, the microstructures of the medicinal materials before and after extraction were studied by scanning electron microscopy(SEM). Furthermore, the extraction efficiency of different extraction methods and the 2, 2-diphenyl-1-picrylhydrazyl(DPPH) radical scavenging activities of the extracts were investigated. The optimal conditions for extracting chlorogenic acid and cynaroside were as follows: ethanol concentration, 60%; extraction pressure, 400 MPa; extraction time, 2 min; extraction temperature, 30 °C; and the solid/liquid ratio, 1 : 50. Under these conditions, the yields of chlorogenic acid and cynaroside were raised to 4.863% and 0.080%, respectively. Compared with other extraction methods, such as heat reflux extraction(HRE), ultrasonic extraction(UE), and Sohxlet extraction(SE), the UPE method showed several advantages, including higher extraction yield, shorter extraction time, lower energy consumption, and higher purity of the extracts. This study could help better utilize L. japonica flower buds as a readily accessible source of natural antioxidants in food and pharmaceutical industries. | HU Wen GUO Ting JIANG Wen-Jun DONG Guang-Li CHEN Da-Wei YANG Shi-Lin LI He-Ran | 2015 | Chinese Journal of Natural Medicines2015，13，6： | 15 |
| 7 | COVID-19: Challenges to GIS with Big Data显示文摘The outbreak of the 2019 novel coronavirus disease(COVID-19)has caused more than 100,000 people infected and thousands of deaths.Currently,the number of infections and deaths is still increasing rapidly.COVID-19 seriously threatens human health,production,life,social functioning and international relations.In the fight against COVID-19,Geographic Information Systems(GIS)and big data technologies have played an important role in many aspects,including the rapid aggregation of multi-source big data,rapid visualization of epidemic information,spatial tracking of confirmed cases,prediction of regional transmission,spatial segmentation of the epidemic risk and prevention level,balancing and management of the supply and demand of material resources,and socialemotional guidance and panic elimination,which provided solid spatial information support for decision-making,measures formulation,and effectiveness assessment of COVID-19 prevention and control.GIS has developed and matured relatively quickly and has a complete technological route for data preparation,platform construction,model construction,and map production.However,for the struggle against the widespread epidemic,the main challenge is finding strategies to adjust traditional technical methods and improve speed and accuracy of information provision for social management.At the data level,in the era of big data,data no longer come mainly from the government but are gathered from more diverse enterprises.As a result,the use of GIS faces difficulties in data acquisition and the integration of heterogeneous data,which requires governments,businesses,and academic institutions to jointly promote the formulation of relevant policies.At the technical level,spatial analysis methods for big data are in the ascendancy.Currently and for a long time in the future,the development of GIS should be strengthened to form a data-driven system for rapid knowledge acquisition,which signifies ts that GIS should be used to reinforce the social operation parameterization of models and methods,especially when providing support for social management. | Chenghu Zhou Fenzhen Su Tao Pei An Zhang Yunyan Du Bin Luo Zhidong Cao Juanle Wang Wen Yuan Yunqiang Zhu Ci Song Jie Chen Jun Xu Fujia Li Ting Ma Lili Jiang Fengqin Yan Jiawei Yi Yunfeng Hu Yilan Liao Han Xiao | 2020 | Geography and Sustainability2020，1，1： | 13 |
| 8 | Arrangement of High-standard Basic Farmland Construction Based on Village-region Cultivated Land Quality Uniformity显示文摘As an important constitute of land consolidation, high-standard basic farmland construction is an important means to protect the quantity, quality and ecological environment of cultivated land. Its target not only lies in the increase of cultivated land quantity, but also the improvement of cultivated land quality, agricultural production conditions and ecosystem environments. In the present study, the quality evaluation method and construction arrangement of cultivated land were explored to facilitate the process of decision-making and implementation for high-standard basic farmland construction(HSBFC) with administrative village as the unit. Taking the land comprehensive improvement project area in Quzhou County, Handan City, Hebei Province as a case study, the whole process of the study comprised of three steps: 1) establishment of the evaluation model of cultivated land quality uniformity based on regional optimum cultivated land quality, and construction of the uniformity evaluation index system from the aspects of soil fertility quality, engineering quality, spatial quality and eco-environment quality, according to the new concept of cultivated land quality; 2) calculation of cultivated land quality uniformity by grading indicators, assigning scores and weighting sums, exploring the local homogenization characteristics of regional cultivated land quality through spatial autocorrelation analysis, and analyzing the constraints and transformative potential of barrier factors; 3) arrangement of HSBFC according to the principle of concentration, continuity and priority to the easy operation. The results revealed that the value of farmland quality uniformity for the administrative villages in the study area was between 7.76 and 21.96, and there was a difference between various administrative villages. The regional spatial autocorrelation patterns included High-High(HH), Low-Low(LL), High-Low(HL) and Low-High(LH). These indicate that regional cultivated land quality has local homogenization characteristics. The most restrictive factors in the study area were the medium and low transformation difficulty indexes, including soil organic matter content, farmland shelterbelt network density, field regularity and scale of the field. In addition, there were also high transformation difficulty indicators in some areas, such as sectional configuration. The project area was divided into four partitions: major construction area, secondary construction area, general construction area, and conditional construction area. The cultivated land area of each subarea was 1538.85 ha, 1224.27 ha, 555.93 ha, and 1666.63 ha, respectively. This comprised of 30.87%, 24.56%, 11.15% and 33.42% of the total project area, respectively. The evaluation model and index system could satisfy the evaluation of farmland quality and diagnosis of obstacle factors to facilitate the subsequent construction decision. The present study provides reference for the practice of regional HSBFC, and a new feasible idea and method for related studies. | SONG Wen WU Kening ZHAO Huafu ZHAO Rui LI Ting | 2019 | Chinese Geographical Science2019，29，2： | 12 |

| 12 | Carnosic acid enhances the anti-lung cancer effect of cisplatin by inhibiting myeloid-derived suppressor cells显示文摘Cisplatin and other platinum-based drugs are used frequently for treatment of lung cancer. However, their clinical performance are usually limited by drug resistance or toxic effects. Carnosic acid, a polyphenolic diterpene isolated from Rosemary(Rosemarinus officinalis), has been reported to have several pharmacological and biological activities. In the present study, the combination effect of cisplatin plus carnosic acid on mouse LLC(Lewis lung cancer) xenografts and possible underlying mechanism of action were examined. LLC-bearing mice were treated with intraperitoneal injection with cisplatin, oral gavage with carnosic acid, or combination with cisplatin and carnosic acid, respectively. Combination of carnosic acid and cisplatin yielded significantly better anti-growth and pro-apoptotic effects on LLC xenografts than drugs alone. Mechanistic study showed that carnosic acid treatment boosted the function of CD8^+T cells as evidenced by higher IFN-γ secretion and higher expression of FasL, perforin as well as granzyme B. In the meantime, the proportion of MDSC(myeloid-derived suppressor cells) in tumor tissues were reduced by carnosic acid treatment and the mRNA levels of iNOS2, Arg-1, and MMP9, which are the functional markers for MDSC, were reduced. In conclusion, our study proved that the functional suppression of MDSC by carnosic acid promoted the lethality of CD8^+T cells, which contributed to the enhancement of anti-lung cancer effect of cisplatin. | LIU Wen WU Tian-Cong HONG Dong-Mei HU Yue FAN Ting GUO Wen-Jie XU Qiang | 2018 | Chinese Journal of Natural Medicines2018，16，12： | 11 |

| 14 | Effects of phosphorus and nitrogen limitation on PHA production in activated sludge显示文摘The effects of phosphorus and nitrogen limitation on polyhydroxyalkanoate(PHA) production and accumulation by activated sludge biomass with acetate as a carbon source were investigated.Pre-selected influent carbon-phosphorus(C:P,W/W) of 100,160,250,500 and 750,and carbon-nitrogen(C:N,W/W) of 20,60,100,125 and 180 were applied in the phosphorus limitation experiments and the nitrogen limitation experiments,respectively.The maximum PHA accumulation up to 59%of the cell dry weight with a PHA productivity of 1.61 mg PHA/mg COD consumed was observed at the C:N 125 in the nitrogen limitation experiment.This value was much higher than that obtained in previous studies with a normal substrate feeding.The study showed that activated sludge biomass would produce more polyhydroxybutyrate than polyhydroxyvalerate under the stress of nutrient limitation,especially under phosphorus limitation conditions.The experimental result also indicated that both phosphorus and nitrogen limitation may cause sludge bulking. | Qinxue Wen,Zhiqiang Chen,Ting Tian,Wei Chen State Key Laboratory of Urban Water Resource and Environment,Harbin Institute of Technology,Harbin 150090,China | 2010 | Journal of Environmental Sciences2010，22，10： | 9 |
| 15 | Plasma metabolomic and lipidomic alterations associated with COVID-19显示文摘The pandemic of the coronavirus disease 2019(COVID-19)has become a global public health crisis.The symptoms of COVID-19 range from mild to severe,but the physiological changes associated with COVID-19 are barely understood.In this study,we performed targeted metabolomic and lipidomic analyses of plasma from a cohort of patients with COVID-19 who had experienced different symptoms.We found that metabolite and lipid alterations exhibit apparent correlation with the course of disease in these patients,indicating that the development of COVID-19 affected their whole-body metabolism.In particular,malic acid of the TCA cycle and carbamoyl phosphate of the urea cycle result in altered energy metabolism and hepatic dysfunction,respectively.It should be noted that carbamoyl phosphate is profoundly down-regulated in patients who died compared with patients with mild symptoms.And,more importantly,guanosine monophosphate(GMP),which is mediated not only by GMP synthase but also by CD39 and CD73,is significantly changed between healthy subjects and patients with COVID-19,as well as between the mild and fatal cases.In addition,dyslipidemia was observed in patients with COVID-19.Overall,the disturbed metabolic patterns have been found to align with the progress and severity of COVID-19.This work provides valuable knowledge about plasma biomarkers associated with COVID-19 and potential therapeutic targets,as well as an important resource for further studies of the pathogenesis of COVID-19. | Di Wu Ting Shu Xiaobo Yang Jian-Xin Song Mingliang Zhang Chengye Yao Wen Liu Muhan Huang Yuan Yu Qingyu Yang Tingju Zhu Jiqian Xu Jingfang Mu Yaxin Wang Hong Wang Tang Tang Yujie Ren Yongran Wu Shu-Hai Lin Yang Qiu Ding-Yu Zhang You Shang Xi Zhou | 2020 | National Science Review2020，7，7： | 9 |
| 16 | Reduction of Plasma MicroRNA-21 is Associated with Chemotherapeutic Response in Patients with Non-small Cell Lung Cancer显示文摘Objective: To examine plasma microRNA-21 (miR-21) level in patients with non-small cell lung cancer (NSCLC) and its potential correlation with chemotherapeutic response. Methods: 77 NSCLC patients and 36 age and sex-matched healthy controls were included. Plasma miR-21 concentration was examined using a quantitative real-time reverse transcription polymerase chain reaction assay (qRT-PCR). Potential correlation between plasma mir-21 concentrations with chemotherapeutic responses was analyzed in 35 patients with advanced NSCLC (stages IIIB and IV). Results: Plasma miR-21 was significantly higher in NSCLC patients relative to the healthy controls (P<0.0001). As a biomarker, plasma mir-21 had a receiver operating characteristic (ROC) curve area of 0.729 with 61.04% sensitivity and 83.33% specificity. Chemotherapeutic response in the 35 patients with advanced NSCLC (stages IIIB and IV) included partial response (PR) (n=11), stable disease and progression disease (SD+PD) (n=24). The overall response rate (CR+PR) was 31.4%. Plasma miR-21 in patients who achieved PR was significantly lower than those who did not respond (SD+PD) (P=0.0487), and comparable to that of the healthy controls (P=0.2744). Conclusion: Plasma miR-21 is a good biomarker for NSCLC, and could be used to predict responses to chemotherapy. | Juan Wei Lian-ke Liu Wen Gao Cheng-jun Zhu Yi-qian Liu Ting Cheng Yong-qian Shu | 2011 | Chinese Journal of Cancer Research2011，23，2： | 9 |
| 17 | An in vitro and finite element study of load redistribution in the midfoot显示文摘A good knowledge of midfoot biomechanics is important in understanding the biomechanics of the entire foot,but it has never been investigated thoroughly in the literature.This study carried out in vitro experiments and finite element analysis to investigate the midfoot biomechanics.A foot-ankle finite element model simulating the mid-stance phase of the normal gait was developed and the model validated in in vitro experimental tests.Experiments used seven in vitro samples of fresh human cadavers.The simulation found that the first principal stress peaks of all midfoot bones occurred at the navicular bone and that the tensile force of the spring ligament was greater than that of any other ligament.The experiments showed that the longitudinal strain acting on the medial cuneiform bone was-26.2±10.8μ-strain,and the navicular strain was-240.0±169.1μ-strain along the longitudinal direction and 65.1±25.8μ-strain along the transverse direction.The anatomical position and the spring ligament both result in higher shear stress in the navicular bone.The load from the ankle joint to five branches of the forefoot is redistributed among the cuneiforms and cuboid bones.Further studies on the mechanism of loading redistribution will be helpful in understanding the biomechanics of the entire foot. | NIU Wen Xin TANG Ting Ting ZHANG Ming JIANG Cheng Hua FAN Yu Bo | 2014 | Science China(Life Sciences)2014，57，12： | 8 |
| 18 | Association between Plasma Metal Levels and Diabetes Risk: a Case-control Study in China显示文摘Objective Many metals, some of which have been classified as environmental endocrine disruptors, are used extensively in everyday consumer products and are ubiquitous in our living environment. In the present study, we aimed to explore the associations between the prevalence risk of type 2 diabetes and plasma levels of 20 trace elements as well as those of heavy metals in a Han Chinese population. Methods We conducted a case-control study to investigate the associations between plasma concentrations of 20 metals and diabetes in Jiangsu province. A total of 122 newly diagnosed cases of type 2 diabetes and 429 matched controls were recruited from community physical examinations in Suzhou City of Jiangsu Province. Plasma metal levels were measured by inductively-coupled plasma mass spectrometry. Results After adjusting for confounders, plasma vanadium, chromium, manganese, copper, zinc, arsenic, selenium, strontium, palladium, cadmium, cesium, and barium were associated with diabetes risk(P < 0.05). The adjusted OR increased with increasing concentration of vanadium, manganese, copper, zinc, and cesium. Conclusion Many metals, including manganese, copper, zinc, arsenic, selenium, and cadmium in plasma, are associated with the morbidity of diabetes. Monitoring of environmental metal levels and further studies are urgently needed. | LI Xiu Ting YU Peng Fei GAO Yan GUO Wen Hui WANG Jun LIU Xin GU Ai Hua JI Gui Xiang DONG Qiu WANG Bo Shen CAO Ying ZHU Bao Li XIAO Hang | 2017 | Biomedical and Environmental Sciences2017，30，7： | 8 |
| 19 | Curcumenol triggered ferroptosis in lung cancer cells via lncRNA H19/miR-19b-3p/FTH1 axis显示文摘Curcumenol,an effective ingredient of Wenyujin,has been reported that exerted its antitumor potential in a few cancer types.However,the effect and molecular mechanism of curcumenol in lung cancer are largely unknown.Here,we found that curcumenol induced cell death and suppressed cell proliferation in lung cancer cells.Next,we demonstrated that ferroptosis was the predominant method that contributed to curcumenol-induced cell death of lung cancer in vitro and vivo for the first time.Subsequently,using RNA sequencing,we found that the long non-coding RNA H19(lncRNA H19)was significantly downregulated in lung cancer cells treated with curcumenol,when compared to untreated controls.Overexpression of lncRNA H19 eliminated the anticancer effect of curcumenol,while lncRNA H19 knockdown promoted ferroptosis induced by curcumenol treatment.Mechanistically,we showed that lncRNA H19 functioned as a competing endogenous RNA to bind to miR-19b-3p,thereby enhanced the transcription activity of its endogenous target,ferritin heavy chain 1(FTH1),a marker of ferroptosis.In conclusion,our data show that the natural product curcumenol exerted its antitumor effects on lung cancer by triggering ferroptosis,and the lncRNA H19/miR-19b-3p/FTH1 axis plays an essential role in curcumenol-induced ferroptotic cell death.Therefore,our findings will hopefully provide a valuable drug for treating lung cancer patients. | Ruonan Zhang Ting Pan Yu Xiang Mingming Zhang Han Xie Zimao Liang Bi Chen Cong Xu Jing Wang Xingxing Huang Qianru Zhu Ziming Zhao Quan Gao Chengyong Wen Wencheng Liu Weirui Ma Jiao Feng Xueni Sun Ting Duan Elaine Lai-Han Leung Tian Xie Qibiao Wu Xinbing Sui | 2022 | Bioactive Materials2022，7，7： | 8 |
| 20 | Global warming projections using the human–earth system model BNU-HESM1.0显示文摘Future climate change is usually projected by coupled earth system models under specific emission scenarios designed by integrated assessment models(IAMs),and this offline approach means there is no interaction between the coupled earth system models and the IAMs.This paper introduces a new method to design possible future emission scenarios and corresponding climate change, in which a simple economic and climate damage component is added to the coupled earth system model of Beijing Normal University(BNU-ESM). With the growth of population and technological expertise and the declining emission-to-output ratio described in the Dynamic Integrated Climate-Economy model, the projected carbon emission is 13.7 Gt C, resulting in a 2.4 °C warming by the end of the twenty-first century(2080–2099) compared with1980–1999. This paper also suggests the importance of the land and ocean carbon cycle in determining the CO2 concentration in the atmosphere. It is hoped that in the near future the next generation of coupled earth system models that include both the natural system and the social dimension will be developed. | Shili Yang Wenjie Dong Jieming Chou Jinming Feng Zhigang Wei Yan Guo Xiaohang Wen Ting Wei Di Tian Xian Zhu Zhiyong Yang | 2016 | Science Bulletin2016，61，23： | 7 |
