| 1 | Prevalence of Atrial Fibrillation in China and Its Risk Factors显示文摘Objective To study the prevalence of atrial fibrillation(AF)and the relation with its risk factors in China.Methods A total of 19 363 participants(8635 males and 10 728 females) aged ≥35 years in geographically dispersed urban and rural regions of China were included in this cross-sectional survey.All participants received questionnaire,physical and blood examination.Echocardiography were performed for AF patients found in the survey.Results Of the 19 363 participants,199 were diagnosed with AF.The estimated age-standardized prevalence of AF was 0.78% in men and 0.76% in women.The prevalence of AF in participants aged <60 years was 0.41% in men and 0.43% in women,and was 1.83% in both men and women aged ≥60 years.About 19.0% of males and 30.9% of females with AF were diagnosed with valve disease.Age-and sex-adjusted multivariable logistic regression analysis revealed that myocardial infarction,left ventricular hypertrophy(LVH),obesity,and alcohol consumption were associated with a increased risk of AF(P<0.05).Conclusion The age standardized prevalence of AF is 0.77% in the participants enrolled in the present study.The number of AF cases aged ≥35 years is 5.26 million according to 2010 Chinese Census.Most risk factors for AF,identified mainly in Western countries,are also detected in China. | LI Ying WU Yang Feng CHEN Ke Ping LI Xian ZHANG Xing XIE Gao Qiang WANG Fang Zheng ZHANG Shu | 2013 | Biomedical and Environmental Sciences2013，26，9： | 48 |
| 2 | Pretreatment HIV drug resistance in adults initiating antiretroviral therapy in China,2017显示文摘Background:After the scale-up of antiretroviral therapy(ART)for HIV infected people,increasing numbers of patients have pretreatment drug resistance(PDR).In this study,the prevalence of PDR was evaluated in adults initiating antiretroviral therapy in China.Methods:Blood samples were obtained from 1943 patients who initiated antiretroviral therapy(ART)in 2017 from 13 provinces or cities in China.Pol sequences were used to analyze drug resistance and construct transmission networks.Logistic regression model was used to estimate the potential factors associated with PDR.Results:In total,1711 eligible patients(76.0%male;87.8%aged≥25 years)were included,of which 117(6.8%)had PDR.The highest rates of PDR were 12.2%in Liangshan Prefecture of Sichuan and 9.3 and 8.9%in Dehong and Lincang Prefecture of Yunnan.A multivariate logistic regression analysis revealed that PDR was significantly higher among intravenous drug users(adjusted Odds Ratio(aOR)=2.64,95%CI:1.57–4.44)and individuals from Liangshan,Dehong,and Lincang(aOR=2.04,95%CI:1.26–3.30).In total,754 sequences were used to generate 164 transmission networks.Five transmission networks had two or three sequences containing the same mutations,two networks contained subjects from Liangshan,and one network contained subjects from Dehong.Conclusions:Overall,the PDR prevalence was moderate,with a particularly high prevalence in areas with severe HIV epidemics.These results indicate the importance of continuous PDR monitoring in patients initiating antiretroviral therapy. | Rui-Hua Kang Shu-Jia Liang Yan-Ling Ma Shu Liang Lin Xiao Xin-Hui Zhang Hong-Yan Lu Xiao-Qin Xu Shui-Bin Luo Xiao-Guang Sun Lin Chen Jian-Mei He Guo-Hui Wu Ling-Jie Liao Hui Xing Yi-Ming Shao Yu-Hua Ruan | 2020 | Infectious Diseases of Poverty2020，9，3： | 17 |
| 3 | An Optimization Algorithm for Service Composition Based on an Improved FOA显示文摘Large-scale service composition has become an important research topic in Service-Oriented Computing(SOC). Quality of Service(Qo S) has been mostly applied to represent nonfunctional properties of web services and to differentiate those with the same functionality. Many studies for measuring service composition in terms of Qo S have been completed. Among current popular optimization methods for service composition, the exhaustion method has some disadvantages such as requiring a large number of calculations and poor scalability. Similarly,the traditional evolutionary computation method has defects such as exhibiting slow convergence speed and falling easily into the local optimum. In order to solve these problems, an improved optimization algorithm, WS FOA(Web Service composition based on Fruit Fly Optimization Algorithm) for service composition, was proposed, on the basis of the modeling of service composition and the FOA. Simulated experiments demonstrated that the algorithm is effective, feasible, stable, and possesses good global searching ability. | Yiwen Zhang Guangming Cui Yan Wang Xing Guo Shu Zhao | 2015 | Tsinghua Science and Technology2015，20，1： | 11 |
| 4 | Synthesis and Performance of Polyurethane Coated Urea as Slow/controlled Release Fertilizer显示文摘Polyurethane coated urea slow/controlled release fertilizer was prepared based on urea granules, isocyanate, polyols and paraffin. Isocyanate reacted with polyols to synthesize the polyurethane skin layer on urea granules surface. Paraffin serves as a lubricant during syntheses of polyurethane skin layers. The structure and nutrient release characteristics of the polyurethane skin layers were investigated by FTIR, SEM and TG. Urea nitrogen slow-release behavior of the polyurethane coated urea was tested. The experimental results indicated that compact and dense polyurethane skin layers with a thickness of 10-15 μm were formed on urea surface, the urea nitrogen slow-release time can reach 40-50 days. Paraffin proves to play a key role in inhibiting water to penetrate into urea, but excessive addition would decrease the polyurethane crosslinking density. | 李青山 WU Shu RU Tiejun 王利民 XING Guangzhong WANG Jinming | 2012 | Journal of Wuhan University of Technology(Materials Science)2012，27，1： | 10 |
| 5 | CP-25 reverses prostaglandin E4 receptor desensitization-induced fibroblast-like synoviocyte dysfunction via the G protein-coupled receptor kinase 2 in autoimmune arthritis显示文摘Paeoniflorin-6’-O-benzene sulfonate (CP-25) is a novel compound derived from paeoniflorin that has been demonstrated to have therapeutic effects in a rat model of rheumatoid arthritis (RA). However, the underlying mechanism has not been elucidated to date. We explored this mechanism in the present study by treating rats with adjuvant arthritis (AA) with CP-25. We found that the membrane EP4 protein level was downregulated;whereas, GRK2 was upregulated, inflbroblast-like synoviocyte (FLS)s of AA rats. Prostaglandin (PGE)2 stimulated FLS proliferation and enhanced the membrane EP4 receptor protein level;the latter was reversed by the administration of an EP4 receptor agonist, whereas the membrane GRK2 protein level gradually increased. The changes in the EP4 receptor and GRK2 expression were enhanced by TNF-α, and the former was accompanied by an alteration in the cyclic (c) AMP level. The EP4 receptor agonist stimulation increased the association between GRK2 and the EP4 receptor. GRK2 knockdown abrogated the abnormalities in FLS proliferation. The CP-25 treatment (100 mg/kg) suppressed joint infiammation with an efficacy that was similar to that of methotrexate. This finding was associated with EP4 upregulation and GRK2 downregulation in FLSs. Thus, GRK2 plays an important role in the abnormal FLS proliferation observed in AA possibly by promoting EP4 receptor desensitization and decreasing the cAMP level. Our results demonstrate that CP-25 has therapeutic potential for the treatment of human RA via GRK2 regulation. | Xiao-yi Jia Yan Chang Fang Wei Xing Dai Yu-jing Wu Xiao-jing Sun Shu Xu Hua-xun Wu Chun Wang Xue-zhi Yang Wei Wei | 2019 | Acta Pharmacologica Sinica2019，40，8： | 10 |
| 6 | Sintilimab versus docetaxel as second-line treatment in advanced or metastatic squamous non-small-cell lung cancer:an open-label,randomized controlled phase 3 trial(ORIENT-3)显示文摘Background:Treatment options for Chinese patients with locally advanced or metastatic squamous-cell non-small-cell lung cancer(sqNSCLC)after failure of first-line chemotherapy are limited.This study(ORIENT-3)aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second-line treatment in patients with locally advanced or metastatic sqNSCLC.Methods:ORIENT-3 was an open-label,multicenter,randomized controlled phase 3 trial that recruited patients with stage IIIB/IIIC/IV sqNSCLC after failure with first-line platinum-based chemotherapy.Patients were randomized in a 1:1 ratio to receive either 200 mg of sintilimab or 75 mg/m^(2) of docetaxel intravenously every 3 weeks,stratified by the Eastern Cooperative Oncology Group performance status.The primary endpoint was overall survival(OS)in the full analysis set(FAS).Secondary endpoints included progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),duration of response(DoR)and safety.Results:Between August 25,2017,and November 7,2018,290 patients were randomized.For FAS,10 patients fromthe docetaxel armwere excluded.Themedian OS was 11.79(n=145;95%confidence interval[CI],10.28-15.57)months with sintilimab versus 8.25(n=135;95%CI,6.47-9.82)months with docetaxel(hazard ratio[HR]:0.74;95%CI,0.56-0.96;P=0.025).Sintilimab treatment significantly prolonged PFS(median 4.30 vs.2.79 months;HR:0.52;95%CI,0.39-0.68;P<0.001)and showed higher ORR(25.50%vs.2.20%,P<0.001)and DCR(65.50%vs.37.80%,P<0.001)than the docetaxel arm.The median DoRwas 12.45(95%CI,4.86-25.33)months in the sintilimab arm and 4.14(95%CI,1.41-7.23)months in the docetaxel arm(P=0.045).Treatment-related adverse events of grade≥3were reported in 26(18.1%)patients in the sintilimab arm and 47(36.2%)patients in the docetaxel arm.Exploratory biomarker analysis showed potential predictive values of expression levels of two transcription factors,including OVOL2(HR:0.35;P<0.001)and CTCF(HR:3.50;P<0.001),for sintilimab treatment.Conclusions:Compared with docetaxel,sintilimab significantly improved the OS,PFS,and ORR of Chinese patients with previously treated locally advanced or metastatic sqNSCLC. | Yuankai Shi Lin Wu Xinmin Yu Puyuan Xing Yan Wang Jianying Zhou Airong Wang Jianhua Shi Yi Hu Ziping Wang Guangyu An Yong Fang Sanyuan Sun Caicun Zhou Changli Wang Feng Ye Xingya Li Junye Wang Mengzhao Wang Yunpeng Liu Yanqiu Zhao Ying Yuan Jifeng Feng Zhendong Chen Jindong Shi Tao Sun Gang Wu Yongqian Shu Qisen Guo Yi Zhang Yong Song Shucai Zhang Yuan Chen Wei Li Hongrui Niu Wenwei Hu Lijun Wang Jianan Huang Yang Zhang Ying Cheng Zhengdong Wu Bo Peng Jiya Sun Christoph Mancao Yanqi Wang Luyao Sun | 2022 | Cancer Communications2022，42，12： | 8 |
| 7 | A Survey on Smart Agriculture:Development Modes,Technologies,and Security and Privacy Challenges显示文摘With the deep combination of both modern information technology and traditional agriculture,the era of agriculture 4.0,which takes the form of smart agriculture,has come.Smart agriculture provides solutions for agricultural intelligence and automation.However,information security issues cannot be ignored with the development of agriculture brought by modern information technology.In this paper,three typical development modes of smart agriculture(precision agriculture,facility agriculture,and order agriculture)are presented.Then,7 key technologies and 11 key applications are derived from the above modes.Based on the above technologies and applications,6 security and privacy countermeasures(authentication and access control,privacy-preserving,blockchain-based solutions for data integrity,cryptography and key management,physical countermeasures,and intrusion detection systems)are summarized and discussed.Moreover,the security challenges of smart agriculture are analyzed and organized into two aspects:1)agricultural production,and 2)information technology.Most current research projects have not taken agricultural equipment as potential security threats.Therefore,we did some additional experiments based on solar insecticidal lamps Internet of Things,and the results indicate that agricultural equipment has an impact on agricultural security.Finally,more technologies(5 G communication,fog computing,Internet of Everything,renewable energy management system,software defined network,virtual reality,augmented reality,and cyber security datasets for smart agriculture)are described as the future research directions of smart agriculture. | Xing Yang Lei Shu Jianing Chen Mohamed Amine Ferrag Jun Wu Edmond Nurellari Kai Huang | 2021 | IEEE/CAA Journal of Automatica Sinica2021，8，2： | 8 |
| 8 | Identification of biomarkers for hepatocellular carcinoma by semiquantitative immunocytochemistry显示文摘AIM:To investigate the expression of key biomarkers in hepatoma cell lines,tumor cells from patients’blood samples,and tumor tissues.METHODS:We performed the biomarker tests in two steps.First,cells plated on coverslips were used to assess biomarkers,and fluorescence intensities were calculated using the NIH Image J software.The measured values were analyzed using the SPSS19.0 software to make comparisons among eight cell lines.Second,eighty-four individual samples were used to assess the biomarkers’expression.Negative enrichment of the blood samples was performed,and karyocytes were isolated and dropped onto pretreated glass slides for further analysis by immunofluorescence staining.Fluorescence intensities were compared among hepatocellular carcinoma(HCC)patients,chronic HBV-infected patients,and healthy controls following methods similar to those used for cell lines.The relationships between the expression of biomarkers and clinical pathological parameters were analyzed by Spearman rank correlation tests.In addition,we studied the distinct biomarkers’expression with three-dimensional laser confocal microscopy reconstructions,and Kaplan-Meier survival analysis was performed to understand the clinical significance of these biomarkers.RESULTS:Microscopic examination and fluorescence intensity calculations indicated that cytokeratin 8/18/19(CK)expression was significantly higher in six of the seven HCC cell lines examined than in the control cells,and the expression levels of asialoglycoprotein receptor(ASGPR)and glypican-3(GPC3)were higher in all seven HCC cell lines than in the control.Cells obtained from HCC patients’blood samples also displayed significantly higher expression levels of ASGPR,GPC3,and CK than cells from chronic HBV-infected patients or healthy controls;these proteins may be valuable surface biomarkers for identifying HCC circulating tumor cells isolated and enriched from the blood samples.The stem cell-like and epithelial-mesenchymal transition-related biomarkers could be detected on the karyocyte slides.ASGPR and GPC3 were expressed at high levels,and thus three-dimensional reconstructions were used to observe their expression in detail.This analysis indicated that GPC3 was localized in the cytoplasm and membrane,but that ASGPR had a polar localization.Survival analyses showed that expression of GPC3 and ASGPR is associated with a patient’s overall survival(OS).CONCLUSION:ASGPR,GPC3,and CK may be valuable HCC biomarkers for CTC detection;the expression of ASGPR and GPC3 might be helpful for understanding patients’OS. | Hong Mu Kai-Xuan Lin Hong Zhao Shu Xing Cong Li Fang Liu Hai-Zhen Lu Ze Zhang Yu-Lin Sun Xi-Yun Yan Jian-Qiang Cai Xiao-Hang Zhao | 2014 | World Journal of Gastroenterology2014，20，19： | 8 |
| 9 | Qinggan Huoxue Recipe suppresses epithelial-tomesenchymal transition in alcoholic liver fibrosis through TGF-β1/Smad signaling pathway显示文摘AIM: To investigate the mechanism by which Qinggan Huoxue Recipe(QGHXR) inhibits epithelial-to-mesenchymal transition(EMT) in rats with alcoholic liver fibrosis(ALF).METHODS: A total of 75 male SD rats were used to induce ALF. Serum biochemical indicators, includingalanine aminotransferase, aspartate aminotransferase, laminin and hyaluronidase, were measured. Liver histopathological changes were evaluated using hematoxylineosin and Sirius red staining. EMT was examined by analyzing the expression of the epithelial marker E-cadherin and the mesenchymal markers vimentin and fibronectin using RT-PCR and Western blot. The inhibitory effect of QGHXR on EMT markers, as well as its effect on molecules associated with the transforming growth factor(TGF)-β1/Smad signaling pathway, including TGF-β1, Smad3, snail, occludin, ZO-1 and claudin, was also examined.RESULTS: Compared with normal control rats, ALF rats exhibited a decrease in E-cadherin levels(m RNA: ALF 0.16 ± 0.05 vs control 1.00 ± 0.08; protein: ALF 0.09 ± 0.05 vs control 0.70 ± 0.17, P < 0.01) and an increase in vimentin and fibronectin levels(m RNA: 11.43 ± 0.39 vs 1.00 ± 0.19 and 9.91 ± 0.34 vs 1.00 ± 0.44, respectively, P < 0.01; protein: 1.13 ± 0.42 vs 0.09 ± 0.03 and 1.16 ± 0.43 vs 0.09 ± 0.00, respectively, P < 0.01). This indicates that EMT occurred in ALF rats. In addition, the TGF-β1/Smad signaling pathway was activated in ALF rats, as evidenced by the increase in TGF-β1 and snail levels(m RNA: 1.76 ± 0.12 vs 1.00 ± 0.05 and 6.98 ± 0.41 vs 1.00 ± 0.10, respectively, P < 0.01; protein: 1.43 ± 0.05 vs 0.12 ± 0.03 and 1.07 ± 0.29 vs 0.07 ± 0.02, respectively, P < 0.01) and the decrease in Smad3 levels(m RNA: 0.05 ± 0.01 vs 1.00 ± 0.12, P < 0.01; protein: 0.06 ± 0.05 vs 0.89 ± 0.12, P < 0.01). Furthermore, levels of the tight junction markers occludin, ZO-1 and claudin decreased in ALF rats compared with healthy control rats(m RNA: 0.60 ± 0.09 vs 1.00 ± 0.12, 0.11 ± 0.00 vs 1.00 ± 0.12 and 0.60 ± 0.01 vs 1.00 ± 0.08, respectively, P < 0.01; protein: 0.05 ± 0.01 vs 0.87 ± 0.40, 0.09 ± 0.05 vs 0.89 ± 0.18 and 0.04 ± 0.03 vs 0.95 ± 0.21, respectively, P < 0.01). In ALF rats treated with QGHXR, E-cadherin levels increased(m RNA: QGHXR 0.67 ± 0.04 vs ALF model 0.16 ± 0.05, P < 0.01; protein: QGHXR 0.66 ± 0.21 vs ALF model 0.09 ± 0.05, P < 0.01), and vimentin and fibronectin levels decreased(m RNA: 6.57 ± 1.05 vs 11.43 ± 0.39 and 1.45 ± 1.51 vs 9.91 ± 0.34, respectively, P < 0.01; protein: 0.09 ± 0.03 vs 1.13 ± 0.42 and 0.10 ± 0.01 vs 1.16 ± 0.43, respectively, P < 0.01). In addition, QGHXR inhibited the expression of TGF-β1 and increased the expression of Smad3(m RNA: 1.03 ± 0.11 vs 1.76 ± 0.12, 0.70 ± 0.10 vs 0.05 ± 0.01, respectively, P < 0.05 and P < 0.01; protein: 0.12 ± 0.03 vs 1.43 ± 0.05 and 0.88 ± 0.20 vs 0.06 ± 0.05, respectively, P < 0.01). QGHXR treatment also reduced the levels of the EMT-inducing transcription factor snail(m RNA: 2.28 ± 0.33 vs 6.98 ± 0.41, P < 0.01; protein: 0.08 ± 0.02 vs 1.07 ± 0.29, P < 0.01) and increased the occludin, ZO-1 and claudin levels(m RNA: 0.73 ± 0.05 vs 0.60 ± 0.09, 0.57 ± 0.04 vs 0.11 ± 0.00 and 0.68 ± 0.03 vs 0.60 ± 0.01, respectively, P < 0.01, P < 0.01 and P < 0.05; protein: 0.92 ± 0.50 vs 0.05 ± 0.01, 0.94 ± 0.22 vs 0.09 ± 0.05 and 0.94 ± 0.29 vs 0.04 ± 0.03, respectively, P < 0.01). The effects of QGR and HXR on the TGF-β1/Smad signaling pathway weresimilar to that of QGHXR; however, the QGR- and HXRinduced changes in vimentin m RNA levels, the QGRinduced changes in fibronectin m RNA levels and the HXR-induced changes in snail and TGF-β1 m RNA levels were not significant.CONCLUSION: Qinggan Huoxue Recipe inhibits EMT in ALF rats by modulating the TGF-β1/Smad signaling pathway, suggesting that the mechanism underlying the amelioration of ALF induced by QGHXR is associated with this pathway. | Tao Wu Jun-Ming Chen Tie-Gang Xiao Xiang-Bing Shu Han-Chen Xu Li-Li Yang Lian-Jun Xing Pei-Yong Zheng Guang Ji | 2016 | World Journal of Gastroenterology2016，22，19： | 8 |
| 10 | Distribution of sand dunes and sand shifts along the southern fringe of the Mu Us Desert since the Ming Dynasty显示文摘This article takes the two segments of the Ming Great Walls,Dabian and Erbian,and their associated barracks and forts as geographical references. Based on a detailed scrutiny of historical records of the Ming and Qing dynasties,and on field surveys,the southern boundaries of the sand dunes and sand shifts of the Mu Us Desert in the Ming and Qing dynasties are carefully reconstructed. A comparison of the southern boundaries of the sand dunes and sand shifts of the Mu Us Desert in Ming and Qing with the modern boundary revealed in remote sensing imagery clearly shows that the southern boundary of dunes and shifts in the Mu us Desert has expanded only in a few areas and on a small scale. In the area to the south of Changle Fort,along the direction of annually prevailing winds,sand drifts have pene-trated through the Jialu River valley into the loess region and have formed a sand strip of 32 km long and 3 km wide. To the east of Qingping Fort,sand drifts penetrated toward the eastern loess region through the Luhe River valley and have formed another sand strip of 8 km long and 2 km wide. Gener-ally speaking,though the intensity of human activity has been increasing in this area since the Ming Dynasty,the Mu Us Desert has not significantly expanded toward the southeast or southwest. The sand-loess boundary in the southern fringe of the Mu Us Desert has been almost unchanged since the Ming Dynasty. | DENG Hui SHU ShiGuang SONG YuQin XING FuLai | 2007 | Chinese Science Bulletin2007，52，22： | 6 |
| 11 | The broad-spectrum adaptations of hominins in the later period of Late Pleistocene of China—Perspectives from the zooarchaeological studies显示文摘During the climatic fluctuations in the late Late Pleistocene, hominins in China had experienced some significant changes and adaptations in terms of subsistence strategies. Based on the zooarchaeological analyses of the faunal remains from the Shuidougou site of North China and the Ma'anshan site of South China, the present study demonstratively indicates that the broad-spectrum diet and its closely-related resource intensification for hominins were already at their places roughly at 33–35 cal ka BP. Compared to hominins of earlier period, who would have preferentially exploited large and medium-sized ungulates, hunter-gathers at later period had otherwise incorporated more small-sized animals(especially the quick ones, such as birds and hares) into their diet. Meanwhile, hominins of the later time had also greatly accelerated extractions and exploitations of the nutritional yields from the large and medium-sized animals. However, it seems clear from the current study that there was significant difference regarding the potential mechanisms for the broad-spectrum adaptations of hominins in the late Late Pleistocene of China. | ZHANG ShuangQuan ZHANG Yue LI Jing Shu GAO Xing | 2016 | Science China Earth Sciences2016，59，8： | 6 |
| 12 | Structure,Orientation and Finite Element Analysis of the Tail Club of Mamenchisaurus hochuanensis显示文摘The structure and orientation of the posterior extremity (tail club) of the caudal vertebrae of Mamenchisaurus hochuanensis Young and Chao, 1972 from the Upper Jurassic Shangshaximiao Formation has been analyzed to determine the tail club function using Finite Element Analysis. Of the four caudal vertebrae composing the tail club, the second largest (C'1') was probably the most proximal, and is fixed with the preceding sequence of the caudal vertebrae, whereas the smallest (C'4') is free and forms the termination of the tail club. Our analysis also suggests that the tail club is more efficient in lateral swinging rather than up-and-down motion, and that the best region for the tail club to impact is at the spine of the largest of the four caudals (C'2'), with a maximum load for impact at about 450 N. The tail club of Mamenchisaurus hochuanensis probably also had limitations as a defense weapon and was more possibly a sensory organ to improve nerve conduction velocity to enhance the capacity for sensory perception of its surroundings. | XING Lida YE Yong SHU Chunkang PENG Guangzhao YOU Hailu | 2009 | Acta Geologica Sinica(English Edition)2009，83，6： | 5 |

| 15 | Exploration of presence/absence variation and corresponding polymorphic markers in soybean genome显示文摘This study was designed to reveal the genome‐wide distribution of presence/absence variation(PAV) and to establish a database of polymorphic PAV markers in soybean. The 33 soybean whole‐genome sequences were compared to each other with that of Williams 82 as a reference genome. A total of 33,127 PAVs were detected and 28,912 PAV markers with their primer sequences were designed as the database NJAUSoyPAV_1.0. The PAVs scattered on whole genome while only 518(1.8%) overlapped with simple sequence repeats(SSRs) in BARCSOYSSR_1.0database. In a random sample of 800 PAVs, 713(89.13%) showed polymorphism among the 12 differential genotypes. Using 126 PAVs and 108 SSRs to test a Chinese soybean germplasm collection composed of 828 Glycine soja Sieb. et Zucc. and Glycine max(L.) Merr. accessions, the per locus allele number and its variation appeared less in PAVs than in SSRs. The distinctness among alleles/bands of PCR(polymerase chain reaction) products showed better in PAVs than in SSRs, potential in accurate marker‐assisted allele selection. The association mapping results showed SSR t PAV was more powerful than any single marker systems.The NJAUSoyPAV_1.0 database has enriched the source of PCR markers, and may fit the materials with a range of per locus allele numbers, if jointly used with SSR markers. | Yufeng Wang Jiangjie Lu Shouyi Chen Liping Shu Reid G.Palmer Guangnan Xing Yan Li Shouping Yang Deyue Yu Tuanjie Zhao Junyi Gai | 2014 | Journal of Integrative Plant Biology2014，56，10： | 5 |
| 16 | Effect of type 2 diabetes mellitus on flavonoid pharmacokinetics and tissue distribution after oral administration of Radix Scutellaria extract in rats显示文摘Radix Scutellaria is widely applied to the treatment of diabetes mellitus in China. Its main bioactive constituents contain baicalin, wogonoside, oroxyloside, and their aglycones. To investigate the effect of type 2 diabetes mellitus on both pharmacokinetics and tissue distribution of these flavonoid compounds, the six flavonoids in plasma and tissues from the normal and type 2 diabetic rats after oral administration of Radix Scutellaria extract were simultaneously measured by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) method. The results showed that baicalin, wogonoside, and oroxyloside had higher Cmax and AUC values(P < 0.05) in type 2 diabetic rats than that in normal rats and the tissue-distribution behaviors of the six flavonoid compounds in hearts, livers, spleens, lungs, kidneys, brains, pancreas, fat and muscle of the type 2 diabetic rats showed obviously differences from the normal rats(P < 0.05).

| 17 | Bevacizumab biosimilar LY01008 compared with bevacizumab(Avastin)as first-line treatment for Chinese patients with unresectable,metastatic,or recurrent non-squamous non-small-cell lung cancer:A multicenter,randomized,double-blinded,phase Ⅲ trial显示文摘Background:Previous studies have demonstrated the preclinical pharmacological and toxicological consistency,and clinical pharmacokinetic equivalence of bevacizumab biosimilar LY01008 with reference bevacizumab(Avastin).This randomized controlled trial aimed to compare the efficacy and safety of LY01008 with Avastin in first-line treatment of Chinese patients with advanced or recurrent non-squamous non-small cell lung cancer(NSCLC).Methods:StageⅢB-ⅣNSCLC patients with evaluable lesions,good physical status,and adequate organ functions from 67 centers across China were randomized in a ratio of 1:1 to receive LY01008 or Avastin 15 mg/kg intravenously in combination with paclitaxel/carboplatin(combined treatment)for 4-6 cycles,followed by maintenance monotherapy with LY01008 until disease progression,intolerable toxicity,or death.The primary endpoint was objective response rate(ORR)in accordance with Response Evaluation Criteria in Solid Tumors(RECIST)version 1.1 confirmed by independent radiological review committees(IRRC).Secondary endpoints included disease control rate(DCR),duration of response(DoR),progression-free survival(PFS),overall survival(OS),and safety.This study was registered in Clinical Trials.gov(NCT03533127).Results:Between December 15^(th),2017,and May 15^(th),2019,a total of 649 patients were randomized to the LY01008(n=324)or Avastin(n=325)group.As of September 25th,2019 for primary endpoint analysis,589 patients received ORR evaluation,with a median number of combined treatment cycles of 5(range 1-6)andmedian duration of treatment of 3.0(range 0.0-5.1)months.ORRof responseevaluable patients in the LY01008 and Avastin groups were 48.5% and 53.0%,respectively.The stratified ORR ratio was 0.91(90%CI 0.80-1.04,within the prespecified equivalence margin of 0.75-1.33).Up to May 15^(th),2020,with a median follow-up of 13.6(range 0.8-28.4)months,no notable differences in DCR,median DoR,median PFS,median OS,and 1-year OS rate were observed between the LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,or recurrent non-squamous NSCLC patients in the first-line setting. | Yuankai Shi Kaijian Lei Yuming Jia Bingqiang Ni Zhiyong He Minghong Bi Xicheng Wang Jianhua Shi Ming Zhou Qian Sun Guolei Wang Dongji Chen Yongqian Shu Lianke Liu Zhongliang Guo Yong Liu Junquan Yang Ke Wang Ke Xiao LinWu Tienan Yi Debin Sun Mafei Kang Tianjiang Ma Yimin Mao Jinsheng Shi Tiegang Tang Yan Wang Puyuan Xing Dongqing Lv Wangjun Liao Zhiguo Luo Bin Wang Xiaohong Wu Xiaoli Zhu Shuhua Han Qisen Guo Rongyu Liu Zhiwei Lu Jianyong Zhang Jian Fang Changlu Hu Yinghua Ji Guolong Liu Hong Lu Dedong Wu Junhong Zhang Shuyang Zhu Zheng Liu Wensheng Qiu Feng Ye Yan Yu Yanqiu Zhao Qinhong Zheng Jun Chen Zhanyu Pan Yiping Zhang Wenjuan Lian Bo Jiang Bo Qiu Guojun Zhang Hua Zhang Yanju Chen Yuan Chen Hongbing Duan Manxiang Li Shengming Liu Lijun Ma Hongming Pan Xia Yuan Xueli Yuan Yulong Zheng Emei Gao Li Zhao Shumin Wang Can Wu | 2021 | Cancer Communications2021，41，9： | 5 |
| 18 | Magnolol protects against acute gastrointestinal injury in sepsis by down-regulating regulated on activation,normal T-cell expressed and secreted显示文摘BACKGROUND Sepsis is a major medical challenge.Magnolol is an active constituent of Houpu that improves tissue function and exerts strong anti-endotoxin and anti-inflammatory effects,but the mechanism by which it reduces intestinal inflammation in sepsis is yet unclear.AIM To assess the protective effect of magnolol on intestinal mucosal epithelial cells in sepsis and elucidate the underlying mechanisms.METHODS Enzyme-linked immunosorbent assay was used to measure tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),IL-6,and regulated on activation,normal T-cell expressed and secreted(RANTES)levels in serum and ileal tissue in animal studies.The histopathological changes of the ileal mucosa in different groups were observed under a microscope.Cell Counting Kit-8 and cell permeability assays were used to determine the concentration of drug-containing serum that did not affect the activity of Caco2 cells but inhibited lipopolysaccharide(LPS)-induced decrease in permeability.Immunofluorescence and Western blot assays were used to detect the levels of RANTES,inhibitor of nuclear factor kappa-B kinaseβ(IKKβ),phosphorylated IKKβ(p-IKKβ),inhibitor of nuclear factor kappa-B kinaseα(IκBα),p65,and p-p65 proteins in different groups in vitro.RESULTS In rats treated with LPS by intravenous tail injection in the presence or absence of magnolol,magnolol inhibited the expression of proinflammatory cytokines,IL-1β,IL-6,and TNF-αin a dose-dependent manner.In addition,magnolol suppressed the production of RANTES in LPS-stimulated sepsis rats.Moreover,in vitro studies suggested that magnolol inhibited the increase of p65 nucleation,thereby markedly downregulating the production of the phosphorylated form of IKKβin LPS-treated Caco2 cells.Specifically,magnolol inhibited the translocation of the transcription factor nuclear factor-kappa B(NF-κB)from the cytosol into the nucleus and down-regulated the expression level of the chemokine RANTES in LPS-stimulated Caco2 cells.CONCLUSION Magnolol down-regulates RANTES levels by inhibiting the LPS/NF-κB signaling pathways,thereby suppressing IL-1β,IL-6,and TNF-αexpression to alleviate the mucosal barrier dysfunction in sepsis. | Shi-Hao Mao Dan-Dan Feng Xi Wang Yi-Hui Zhi Shu Lei Xi Xing Rong-Lin Jiang Jian-Nong Wu | 2021 | World Journal of Clinical Cases2021，9，34： | 5 |
| 19 | QTL Mapping for Grain Size Traits Based on Extra-Large Grain Rice Line TD70显示文摘Grain size traits, including grain length, grain width and grain thickness, are controlled by quantitative trait loci(QTLs). Many QTLs relating to rice grain size traits had been reported, but their control mechanisms have not yet been elucidated. A recombinant inbred line(RIL) population of 240 lines, deriving from a cross between TD70, an extra-large grain size japonica line with 80 g of 1000-grain weight, and Kasalath, a small grain size indica variety, were constructed and used to map grain size QTLs to a linkage map by using 141 SSR markers in 2010 and 2011. Five QTLs for grain length, six for grain width and seven for grain thickness were detected distributing over chromosomes 2, 3, 5, 7, 9 and 12. Seven QTLs, namely qGL3.1, qGW2, qGW2.2, qGW5.1, qGW5.2, qGT2.3 and qGT3.1, were detected in either of the two years and explained for 56.19%, 4.42%, 29.41%, 10.37%, 7.61%, 21.19% and 17.06% of the observed phenotypic variances on average, respectively. The marker interval RM1347–RM5699 on chromosome 2 was found common for grain length, grain width and grain thickness; qGL3.1 and qGT3.1 were mapped to the same interval RM6080–RM6832 on chromosome 3. All 18 QTL alleles were derived from the large grain parent TD70. Most of the QTLs mapped in the present study were found the same as the genes previously cloned(GW2, GS3 or qGL3, GW5 and GS5), and several were the same as the QTLs(GS7 and qGL-7) previously mapped. Three QTLs, qGL2.2 on chromosome 2, qGW9 and qGT9 on chromosome 9, were first detected. These results laid a foundation for further fine mapping or cloning of these QTLs. | ZHANG Ya-dong ZHANG Ying-hui DONG Shao-ling CHEN Tao ZHAO Qing-yong ZHU Zhen ZHOU Li-hui YAO Shu ZHAO Ling YU Xing WANG Cai-lin | 2013 | Rice science2013，20，6： | 4 |
| 20 | Effect of Shenqi Yangxin decoction on high mobility group box 1and inflammatory signal pathway in a rat model of dilated cardiomyopathy显示文摘OBJECTIVE: To investigate the effects of Shenqi Yangxin decoction(SQYXD) on heart function in a rat model of dilated cardiomyopathy(DCM) and its potential mechanisms.METHODS: Sprague-Dawley rats were randomly divided into normal(10 rats) and DCM(150 rats)groups. DCM was induced by an intraperitoneal injection of adriamycin. Then, DCM baseline group was randomly selected sixteen DCM rats. The remaining DCM rats were randomly divided into DCM control, perindopril, metoprolol, and SQYXD groups. Cardiac function and histological analysis plus biochemical measurement of serum levels of brain natriuretic peptide(BNP), and inflammatory factors were measured. The mRNA and protein expression levels of high-mobility group box 1(HMGB1), Toll-like receptor 4(TLR-4), receptor for advanced glycation end products(RAGE), and nuclear factor-κB(NF-κB) were determined. Myocardial metabolism imaging was performed on the normal, SQYXD and DCM control groups to evaluate the effectiveness of treatments.RESULTS: Rats in the DCM control group exhibited dilated left ventricular diameter, impaired cardiac function, disorganized sarcomere, impaired glucose metabolism, increased heart weight index,and increased levels of BNP, which were improved by treatment with SQYXD. In addition, hearts from rats in the DCM baseline group exhibited significantly higher levels of HMGB1, TLR-4, RAGE, NF-κB,tumor necrosis factor-α, interleukin-1, interleukin-6, interleukin-10, compared with the normal group. Interestingly, the mRNA level of HMGB1 in the DCM baseline group was positively correlated with that of TLR-4, RAGE, NF-κB, BNP, and LVEDD,but negatively correlated with LVEF. SQYXD inhibited the upregulation of HMGB1 expression and its downstream inflammatory factors.CONCLUSION: Shenqi Yangxin decoction effectively reduced the dilated left ventricular diameter and improved heart function in dilated cardiomyopathy. The mechanisms underlying the action on DCM involve regulating the gene and protein expression of HMGB1 and its inflammatory signal pathways in the DCM rat model. | Shen Lijuan Lu Shu Zhou Yonghua Xing Qingmin Zhou Chungang Li Lan | 2018 | Journal of Traditional Chinese Medicine2018，38，6： | 4 |
