| 2 | Achieving maximum power transfer of inductively coupled wireless power transfer system based on dynamic tuning control显示文摘As an emerging research field,inductively coupled wireless power transfer(ICWPT) technology has attracted wide spread attention recently.In this paper,the maximum power transfer performances of four basic topologies labeled as SS,SP,PS and PP are investigated.By modeling the equivalent circuits of these topologies in high frequency(HF),the primary resonance compensation capacitances for maximum power transfer capability are deduced.It is found that these capacitances fluctuate with load resistance change,which is disadvantageous to SP,PS and PP topologies and an obstacle to their practical applications as well.To solve this problem,a phase controlled inductor circuit is proposed.By adjusting the triggering angle,the real-time dynamic tuning control can be achieved to guarantee maximum power transfer.Finally,simulations and experiments show that the proposed method is of great effectiveness and reliability to solve the issue of resonance compensation capacitance fluctuation with load change and to guarantee the flexible applications of all topologies. | QIANG Hao HUANG XueLiang TAN LinLin JI QingJing ZHAO JiaMing | 2012 | Science China(Technological Sciences)2012,55,7: | 23 |
| 3 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020,3,1: | 22 |
| 4 | Repetitive transcranial magnetic stimulation for lower extremity motor function in patients with stroke:a systematic review and network meta-analysis显示文摘Transcranial magnetic stimulation,a type of noninvasive brain stimulation,has become an ancillary therapy for motor function rehabilitation.Most previous studies have focused on the effects of repetitive transcranial magnetic stimulation(rTMS)on motor function in stroke patients.There have been relatively few studies on the effects of different modalities of rTMS on lower extremity motor function and corticospinal excitability in patients with stroke.The MEDLINE,Embase,Cochrane Library,ISI Science Citation Index,Physiotherapy Evidence Database,China National Knowledge Infrastructure Library,and ClinicalTrials.gov databases were searched.Parallel or crossover randomized controlled trials that addressed the effectiveness of rTMS in patients with stroke,published from inception to November 28,2019,were included.Standard pairwise meta-analysis was conducted using R version 3.6.1 with the“meta”package.Bayesian network analysis using the Markov chain Monte Carlo algorithm was conducted to investigate the effectiveness of different rTMS protocol interventions.Network meta-analysis results of 18 randomized controlled trials regarding lower extremity motor function recovery revealed that low-frequency rTMS had better efficacy in promoting lower extremity motor function recovery than sham stimulation.Network meta-analysis results of five randomized controlled trials demonstrated that highfrequency rTMS led to higher amplitudes of motor evoked potentials than low-frequency rTMS or sham stimulation.These findings suggest that rTMS can improve motor function in patients with stroke,and that low-frequency rTMS mainly affects motor function,whereas high-frequency rTMS increases the amplitudes of motor evoked potentials.More highquality randomized controlled trials are needed to validate this conclusion.The work was registered in PROSPERO(registration No.CRD42020147055)on April 28,2020. | Yun-Juan Xie Yi Chen Hui-Xin Tan Qi-Fan Guo Benson Wui-Man Lau Qiang Gao | 2021 | Neural Regeneration Research2021,16,6: | 20 |
| 5 | Mechanical mechanism of overlying strata breaking and development of fractured zone during close-distance coal seam group mining显示文摘This study mainly investigates the mechanical mechanism of overlying strata breaking and the development of fractured zones during close-distance coal seam group mining in the Gaojialiang coal mine.First,a mechanical model for the second'activation'of broken overlying strata is established,and the related mechanical'activation'conditions are obtained.A recursive formula for calculating the separation distance of overlying strata is deduced.Second,a height determining method for predicting the height of fractured zones during close-distance coal seam group mining is proposed based on two values,namely,the separation distance and ultimate subsidence value of overlying strata.This method is applied to calculate the fractured zone heights in nos.20107 and 20307 mining faces.The calculated results are almost equal to the field observation results.Third,a modified formula for calculating the height of a waterflowing fractured zone is proposed.A comparison of the calculated and observed results shows that the errors are small.The height determining method and modified formula not only build a theoretical foundation for water conservation mining at the Gaojialiang coal mine,but also provide a reference for estimating the height of water-flowing fractured zones in other coal mines with similar conditions. | Jianguo Ning Jun Wang Yunliang Tan Qiang Xu | 2020 | International Journal of Mining Science and Technology2020,30,2: | 19 |
| 6 | Natural Variation in CCD4 Promoter Underpins Species-Specific Evolution of Red Coloration in Citrus Peel显示文摘Carotenoids and apocarotenoids act as phytohormones and volatile precursors that influence plant development and confer aesthetic and nutritional value critical to consumer preference.Citrus fruits display considerable natural variation in carotenoid and apocarotenoid pigments.In this study,using an integrated genetic approach we revealed that a 5;c/s-regulatory change at CCD4b encoding CAROTENOID CLEAVAGE DIOXYGENASE 4b is a major genetic determinant of natural variation in C3 0 apocarotenoids responsible for red coloration of citrus peel.Functional analyses demonstrated that in addition the known role in synthesizing 3-citraurin,CCD4b is also responsible for the production of another important C3 0 apocarotenoid pigment,p-citraurinene.Furthermore,analyses of the CCD4b promoter and transcripts from various citrus germplasm accessions established a tight correlation between the presence of a putative 5'c/s-regulatory enhancer within an MITE transposon and the enhanced allelic expression of CCD4b in C3 0 apocarotenoid-rich red-peeled accessions.Phylogenetic analysis provided further evidence that functional diversification of CCD4b and naturally occurring variation of the CCD4b promoter resulted in the stepwise evolution of red peels in mandarins and their hybrids.Taken together,our findings provide new insights into the genetic and evolutionary basis of apocarotenoid diversity in plants,and would facilitate breeding efforts that aim to improve the nutritional and aesthetic value of citrus and perhaps other fruit crops. | Xiongjie Zheng Kaijie Zhu Quan Sun Weiyi Zhang Xia Wang Hongbo Cao Meilian Tan Zongzhou Xie Yunliu Zeng Junli Ye Lijun Chai Qiang Xu Zhiyong Pan Shunyuan Xiao Paul D.Fraser Xiuxin Deng | 2019 | Molecular Plant2019,12,9: | 18 |

| 8 | Mechanical properties, biodegradability and cytocompatibility of biodegradable Mg-Zn-Zr-Nd/Y alloys显示文摘Biodegradable magnesium alloys have been turned out to be a promising candidate for orthopedic applications.In this study,the mechanical properties,degradation behaviorand cytocompatibility of MgZn-Zr-Nd and Mg-Zn-Zr-Y alloys were studied in comparison with pure Mg.Mechanical tests showed that the strength and ductility of Mg-Zn-Zr-Nd and Mg-Zn-Zr-Y alloys were excellent.The corrosion resistance analyzed by electrochemical test and immersion test in alpha modified eagle(α-MEM) medium with 10% fetal bovine serum(FBS) revealed the degradation of Mg-Zn-Zr-Nd and Mg-Zn-Zr-Y alloys were faster than pure Mg at an early stage but slowed down after long time immersion.The metal ion concentrations were consistent with the corrosion rate.Mg-Zn-Zr-Nd alloy shows better mechanical properties than pure Mg and better corrosion resistance than Mg-Zn-Zr-Y alloy.The direct and indirect in vitro tests with MC3 T3-E1 cells demonstrate that Mg-Zn-Zr-Nd shows the best cytocompatibility and osteogenesis.The results suggest that Mg-Zn-Zr-Nd alloy shows an ideal combination of mechanical,corrosive and biological properties.In summary,these results implying the Mg-Zn-Zr-Nd alloy has great potential to benefit the future development of orthopedic applications. | Shi Jin Dan Zhang Xiaopeng Lu Yang Zhang Lili Tan Ying Liu Qiang Wang | 2020 | Journal of Materials Science & Technology2020,47,12: | 12 |
| 9 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018,61,3: | 12 |
| 10 | Toll-like receptor 10 (TLR10) exhibits suppressive effects on inflammation of prostate epithelial cells显示文摘Prostate inflammation (PI) is closely related to the development and progression of chronic prostatic diseases: benign prostatic hyperplasia and prostate cancer. Toll-like receptor (TLR) 2 has been reported to be associated with inflammatory diseases, such as infections, autoimmune diseases, and cancers. Meanwhile, TLR10, which can form heterodimers with TLR2, has been considered an orphan receptor without an exact function. The present study therefore aims to examine the effects of TLR2 and TLR10 on PI. Prostate samples and clinical data were obtained from the patients diagnosed with benign prostatic hyperplasia. The inflammatory cell model was established by adding lipopolysaccharide to RWPE-1 cells. Prostate tissues/cells were examined by histological, molecular, and biochemical approaches. Both TLR2 and TLR10 were found to be expressed in prostate tissues and RWPE-1 cells. mRNA/protein expression levels of TLR2 and TLR10 were both positively correlated with prostate tissue inflammatory grades. Lipopolysaccharide-stimulated RWPE-1 cells expressed higher levels of TLR2, TLR10, high mobility group box 1 (HMGB1), phosphonuclear factor kappa-light-chain-enhancer of activated B-cells P65 (phospho-NF-κB P65), interleukin (IL)-6, and IL-8 than control cells. Moreover, HMGB1, phospho-NF-κB P65, IL-6, and IL-8 were down regulated after TLR2 knockdown and upregulated after TLR10 knockdown in RWPE-1 cells. TLR2 stimulation can activate the inflammatory signaling cascade in prostate epithelial cells. Conversely, TLR10 exhibited suppressive effects on inflammation. With antagonistic functions, both TLR2 and TLR10 were invoIved in PI. TLR10 could be a novel target in modulating inflammatory signal transduction of prostate epithelial cells. | Yu Fan Lu Yang Qiang Wei Yu Ding Zhuang Tang Ping Tan Tao Lin Duan Guo Shi Qiu | 2019 | Asian Journal of Andrology2019,21,4: | 9 |
| 11 | Inhibition of endoplasmic reticulum stress alleviates secondary injury after traumatic brain injury显示文摘Apoptosis after traumatic brain injury has been shown to be a major factor influencing prognosis and outcome. Endoplasmic reticulum stress may be involved in mitochondrial mediated neuronal apoptosis. Therefore, endoplasmic reticulum stress has become an important mechanism of secondary injury after traumatic brain injury. In this study, a rat model of traumatic brain injury was established by lateral fluid percussion injury. Fluorescence assays were used to measure reactive oxygen species content in the cerebral cortex. Western blot assays were used to determine expression of endoplasmic reticulum stress-related proteins. Hematoxylin-eosin staining was used to detect pathological changes in the cerebral cortex. Transmission electron microscopy was used to measure ultrastructural changes in the endoplasmic reticulum and mitochondria. Our results showed activation of the endoplasmic reticulum stress-related unfolded protein response. Meanwhile, both the endoplasmic reticulum stress response and mitochondrial apoptotic pathway were activated at different stages post-traumatic brain injury. Furthermore, pretreatment with the endoplasmic reticulum stress inhibitor, salubrinal(1 mg/kg), by intraperitoneal injection 30 minutes before injury significantly inhibited the endoplasmic reticulum stress response and reduced apoptosis. Moreover, salubrinal promoted recovery of mitochondrial function and inhibited activation of the mitochondrial apoptotic pathway post-traumatic brain injury. These results suggest that endoplasmic reticulum stress might be a key factor for secondary brain injury post-traumatic brain injury. | Hong-Ping Tan Qiang Guo Gang Hua Jun-Xi Chen Jun-Chao Liang | 2018 | Neural Regeneration Research2018,13,5: | 9 |

| 13 | THE DEGRADATION AND BIOCOMPATIBILITY OF WATERBORNE BIODEGRADABLE POLYURETHANES FOR TISSUE ENGINEERING显示文摘To better investigate the degradation and biocompatibility of waterborne biodegradable polyurethanes for tissue engineering, a series of new waterborne biodegradable polyurethanes(PEGPUs) with low degree of crosslinking was synthesized using IPDI, BDO and L-lysine as hard segments, PCL and PEG as soft segment. The bulk structures and properties of the prepared polyurethanes were characterized by Fourier transform infrared spectroscopy(FTIR), differential scanning calorimetry(DSC), tensile mechanical tests and water contact angle(WCA) measurements. The degree of microphase separation was slightly improved because of the lowered crosslinking degree of these PEGPUs in comparison with the high cross-linking degree samples, leading to good mechanical properties, as indicated by DSC and stress-strain data. Moreover, biodegradability of the polyurethanes was evaluated in phosphate buffer solutions(PBS) under different pH values and enzymatic solution at pH 7.4 through weight loss monitoring. The results suggested that the degradation of these PEGPUs was closely related to their bulk and surface properties. And the degradation products didn't show apparent inhibition effect against fibroblasts in vitro. These studies demonstrated that the waterborne biodegradable polyurethanes could find potential use in soft tissue engineering and tissue regeneration. | Ni-jia Song Xia Jiang Jie-hua Li Yong Pang Jian-shu Li Hong Tan Qiang Fu | 2013 | Chinese Journal of Polymer Science2013,31,10: | 8 |
| 14 | Malnutrition and Quality of Life in Chinese Cancer Patients: a Clinical Study of 23,994 Subjects显示文摘Background Malnutrition is common in patients with cancer,and can negatively impact their quality of life(QoL)and even survival.However,there is currently no large data available on the prevalence of malnutrition in Chinese cancer patients.This study evaluated the prevalence of malnutrition and the QoL of Chinese patients with locoregional,recurrent or metastatic cancer.Methods We conducted a nationwide observational,multi-center,hospital-based cross-sectional study within the Chinese Society of Nutritional Oncology(CSNO)Network.All of the patients were diagnosed with one of the following 18 different types of malignant tumors:lung cancer,gastric cancer,liver cancer,colorectal cancer,breast cancer,esophageal cancer,cervical cancer,endometrial cancer,nasopharyngeal carcinoma,malignant lymphoma,leukemia,pancreatic cancer,ovarian cancer,prostate cancer,bladder cancer,brain cancer,biliary tract malignant tumors or gastrointestinal stromal tumors.These patients were enrolled from 72 hospitals located in different regions of China.The patients’nutritional status was evaluated based on the body mass index(BMI),loss of bodyweight,laboratory measurements and patient generated-subjective global assessment(PG-SGA)scores.The cancer patients’physical status and QoL were assessed by the Karnofsky Performance Status(KPS)questionnaire and the European Organization for Research and Treatment of Cancer(EORTC)QLQ-C30 questionnaire,respectively.Results From December 2013 to April 2016,23,994 patients hospitalized for cancer treatment(such as surgery,chemotherapy or radiotherapy)were enrolled in the study.The patients included 12,494(52.9%)males and 11,124(47.1%)females.The mean age was 55.8±13.7 years.The proportions of patients in cancer stagesⅠ,Ⅱ,Ⅲ,Ⅳand uncertain were 11.5%,20.3%,27.5%,30.2%and 10.5%,respectively.Among the 23,994 inpatients,the proportions of patients who were underweight(BMI<18.5 kg/m2),normal(18.5 kg/m2 | Hong Xia Xu Chun Hua Song Zhen Ming Fu Chang Wang Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Fu Xiang Zhou Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Min Weng Qing Hua Yao Jiu Wei Cui Wei Li Han Ping Shi the Investigation on Nutrition Status and Clinical Outcome of Common Cancers(INSCOC)Group | 2021 | Journal of Nutritional Oncology2021,6,1: | 8 |
| 15 | Effects of dietary supplementation with essential oils and protease on growth performance,antioxidation,inflammation and intestinal function of weaned pigs显示文摘This experiment evaluated the impacts of essential oils(EO)and protease(PRO),independently or in combination,on growth performance,antioxidation,inflammation and intestinal function of weaned pigs.One hundred and sixty weaned pigs(21 d of age,BW of 6.74±0.20 kg)were randomly divided into 4 treatments with 8 replicate pens of 5 pigs per pen.Dietary treatments included the following:1)control diet(CON),2)CON with 300 mg/kg essential oils(EO),3)CON with 500 mg/kg protease(PRO),4)CON with 300 mg/kg essential oil and 500 mg/kg protease(EO + PRO).On d 8,one pig from each penwas selected for sampling.The remaining pigs were fed for an additional week and growth performance was monitored during this period.Dietary treatments had no marked effects(P>0.05)on the growth performance of pigs.However,pigs receiving EO diet had higher(P<0.05)serumglutathione peroxidase(GSH-Px)activity,and tended to decrease(P=0.063)serum concentration of tumor necrosis factor-a(TNF-a).In addition,pigs receiving EO diet had higher(P<0.05)abundances of phylum Actinobacteria,and genera Bifidobacterium,and lower(P<0.05)phylum Bacteroidetes and genera Alloprevotella in colonic digesta.Pigs receiving PRO diet decreased(P<0.05)the serum concentration of malondialdehyde(MDA)and diamine oxidase activity,increased(P<0.05)the villus height and the ratio of villus height to crypt depth in duodenum,increased sucrase activity in jejunal mucosa,and also increased the abundance of phylum Actinobacteria in colonic digesta.Furthermore,the synergistic effects of EO and PROwas observed(P<0.05)for pigs with decreasing serum TNF-a concentration and increasing serum GSH-Px activity.Collectively,the results indicated that dietary supplementation of EO and PRO had no significant effects on growth performance of weaned pigs.EO diet appeared to improve antioxidant activity and intestinal microbiota,while PRO diet improved intestinal morphology and digestive enzyme activity,and there was a synergistic effect of EO and PRO on reducing inflammatory parameters in weaned pigs. | Xie Peng Qiang Zhou Cheng Wu Jian Zhao Quan Tan Ying He Liang Hu Zhengfeng Fang Yan Lin Shengyu Xu Bin Feng Jian Li Yong Zhuo Chris Van Ginneken Xuemei Jiang De Wu Lianqiang Che | 2022 | Animal Nutrition2022,,2: | 8 |
| 16 | Molecular mechanisms of tumor resistance to PI3K-mTOR-targeted therapy显示文摘Deregulation of the phosphatidylinositide 3-kinase(PI3K) and mammalian target of rapamycin(mTOR) signaling pathway occurs frequently in a wide range of human cancers and is a major driving force in tumorigenesis.Thus,small molecules targeting this pathway are under active development as anticancer therapeutics.Although small-molecule inhibitors of the PI3K-mTOR pathway have shown promising clinical efficacy against human cancers,the emergence of drug resistance may limit their success in the clinic.To date,several resistance mechanisms,including both PI3K-dependent and-independent mechanisms,have been described.Here,we summarize the current understanding of resistance mechanisms to PI3K-mTOR inhibitors and discuss potential strategies for overcoming resistance for potential clinical application. | Jing Tan Qiang Yu | 2013 | Chinese Journal of Cancer2013,32,7: | 8 |
| 17 | A novel thioredoxin reductase inhibitor inhibits cell growth and induces apoptosis in HL-60 and K562 cells显示文摘Human thioredoxin reductase (TrxR) system is associated with cancer cell growth and anti-apoptosis process. Effects of 1,2-bis(1,2-benzisoselenazolone-3(2H)-ketone)ethane (BBSKE),a novel TrxR inhibitor,were investigated on human leu-kemia cell lines HL-60 and K562. BBSKE treatment induced cell growth inhibition and apoptosis in both cell lines. Apoptosis induced by BBSKE is through Bcl-2/Bax and caspase-3 pathways. Ehrlich's ascites carcinoma-bearing mice were used to inves-tigate the anti-tumor effect of BBSKE in vivo. Tumor-bearing mice treated with BBSKE showed an increase of life span with a comparable effect to cyclophosphamide (CTX). These results suggest a potential usage of BBSKE as a therapeutic agent against non-solid tumors. | Zuo-fu PENG Lin-xiang LAN Fang ZHAO Jing LI Qiang TAN Han-wei YIN Hui-hui ZENG | 2008 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008,9,1: | 7 |
| 18 | News Text Topic Clustering Optimized Method Based on TF-IDF Algorithm on Spark显示文摘Due to the slow processing speed of text topic clustering in stand-alone architecture under the background of big data,this paper takes news text as the research object and proposes LDA text topic clustering algorithm based on Spark big data platform.Since the TF-IDF(term frequency-inverse document frequency)algorithm under Spark is irreversible to word mapping,the mapped words indexes cannot be traced back to the original words.In this paper,an optimized method is proposed that TF-IDF under Spark to ensure the text words can be restored.Firstly,the text feature is extracted by the TF-IDF algorithm combined CountVectorizer proposed in this paper,and then the features are inputted to the LDA(Latent Dirichlet Allocation)topic model for training.Finally,the text topic clustering is obtained.Experimental results show that for large data samples,the processing speed of LDA topic model clustering has been improved based Spark.At the same time,compared with the LDA topic model based on word frequency input,the model proposed in this paper has a reduction of perplexity. | Zhuo Zhou Jiaohua Qin Xuyu Xiang Yun Tan Qiang Liu Neal N.Xiong | 2020 | Computers, Materials & Continua2020,,1: | 7 |
| 19 | The preoperative serum cystatin-C as an independent prognostic factor for survival in upper tract urothelial carcinoma显示文摘Cystatin-C(Cys-C)has been reported as a valuable prognostic biomarker in various malignancies.However,its effect on upper tract urothelial carci noma(UTUC)patie nts has not bee n investigated before.Thus,to explore the impact of Cys-C on survival outcomes in patients undergoing radical nephroureterectomy(RNU),a total of 538 patients with UTUC who underwent RNU between 2005 and 2014 in our center(West China Hospital,Chengdu,China)were included in this study.Kaplan-Meier method and Cox regressi on an a lyses were performed to assess the relationship betwee n Cys-C and survival outcomes using SPSS versi on 22.0.The cutoff value of Cys-C was set as 1.4 mg I1 using the receiver operating characteristic(ROC)curves and Youden index.The mean age of patients included was 66.1±11.1 years,and the media n follow-up durati on was 38(interquartile ran ge:19-56)mon ths.Overall,162(30.1%)patients had elevated Cys-C,and they were much older and had worse renal function than those with Cys-C<1.4 mg I^-1(both P<0.001).Meanwhile,Kaplan-Meier analysis revealed that the group with elevated Cys-C had worse cancer-specific survival(CSS,P=0.001),disease recurrence-free survival(RFS,P=0.003),and overall survival(OS,P<0.001).Multivariable Cox analysis suggested that the elevated Cys-C was identified as an independent prognostic predictor of CSS(hazard ratio[HR]:1.997,95%confidential interval[CI]:1.331-2.996),RFS(HR:1.429,95%CI:1.009-2.023),and OS(HR:1.989,95%CI:1.366-2.896).In conclusion,our result revealed that the elevated preoperative serum Cys-C was significantly associated with worse outcomes in UTUC patients undergoing RNU. | Ping Tan Ming Shi Jie Chen Hang Xu Nan Xie Huan Xu Yong Jiang Jian-Zhong Ai Liang-Ren Liu Lu Yang Qiang Wei | 2019 | Asian Journal of Andrology2019,21,2: | 7 |
| 20 | Validity of the Chinese Version of the Patient-Generated Subjective Global Assessment (PG-SGA) in Lung Cancer Patients显示文摘The prevalence of malnutrition is high among oncology patients in China. Although the Patient- Generated Subjective Global Assessment (PG-SGA) is widely recognized as an important nutritional assessment tool, it has not been validated for Chinese cancer patients. The purpose of this study was to conduct an analysis of nutrition screening and assessment data to validate the Chinese version of the PG-SGA in Chinese patients with lung cancer. This was an observational, cross-sectional study of 2,000 consecutive adult patients with lung cancer treated at several tertiary hospitals in China. Anthropometric and patient descriptive data were collected. The PG-SGA generated a score for the nutritional risk and a global rating for the nutritional status. The internal consistency, external consistency, and construct validity were evaluated, and a known-groups comparison and principal component analyses were conducted to evaluate the reliability and validity of the PG-SGA. The known-groups comparison demonstrated the ability of the PG-SGA to differentiate lung cancer patients of different nutritional and body mass index (BMI) groups. A confirmatory factor analysis supported the original four-factor structure of the PG-SGA. In terms of the internal and external consistency, the PG-SGA demonstrated intra-class correlation coefficients (ICC) up to 0.987. Alternative form validity was also demonstrated between Box 4 of the PG-SGA and the Karnofsky Performance Status score, with excellent external consistency (r = 0.972, P < 0.001). The construct validity was supported, and selected questionnaire dimensions were evident in the principal component analysis. Significant Spearman correlations (P < 0.001) were demonstrated. The Chinese version of the PG-SGA demonstrated significant reliability and sufficient exploratory properties to support its validity. It seems to be a valid tool that can be used to access the nutritional status of Chinese lung cancer patients. The validity of the PG-SGA in Chinese cancer patients warrants further investigation in other cancer types. | Zhen Ming Fu Hong Xia Xu Chun Hua Song Wei Li Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Chang Wang Han Ping Shi The Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) Group | 2016 | Journal of Nutritional Oncology2016,1,1: | 7 |
