| 2 | Destruction of the North China Craton显示文摘A National Science Foundation of China(NSFC) major research project,Destruction of the North China Craton(NCC),has been carried out in the past few years by Chinese scientists through an in-depth and systematic observations,experiments and theoretical analyses,with an emphasis on the spatio-temporal distribution of the NCC destruction,the structure of deep earth and shallow geological records of the craton evolution,the mechanism and dynamics of the craton destruction.From this work the following conclusions can be drawn:(1) Significant spatial heterogeneity exists in the NCC lithospheric thickness and crustal structure,which constrains the scope of the NCC destruction.(2) The nature of the Paleozoic,Mesozoic and Cenozoic sub-continental lithospheric mantle(CLM) underneath the NCC is characterized in detail.In terms of water content,the late Mesozoic CLM was rich in water,but Cenozoic CLM was highly water deficient.(3) The correlation between magmatism and surface geological response confirms that the geological and tectonic evolution is governed by cratonic destruction processes.(4) Pacific subduction is the main dynamic factor that triggered the destruction of the NCC,which highlights the role of cratonic destruction in plate tectonics. | ZHU RiXiang XU YiGang ZHU Guang ZHANG HongFu XIA QunKe ZHENG TianYu | 2012 | Science China Earth Sciences2012，55，10： | 119 |

| 7 | Effect of various crop rotations on rice yield and nitrogen use efficiency in paddy–upland systems in southeastern China显示文摘To evaluate the effects of various rotation systems on rice grain yield and N use efficiency, a paddy–upland cropping experiment(2013–2016) was conducted in southeastern China. The experiment was designed using six different rice––winter crop rotations: rice–fallow(RF),rice–wheat(RW), rice–potato with rice straw mulch(RP), rice–green manure(Chinese milk vetch; RC–G), rice–oilseed rape(RO), and rice–green manure crop(oilseed rape with fresh straw incorporated into soil at flowering; RO–G) and three N rates, N0(0 kg N ha-1), N1(142.5 kg N ha-1), and N2(202.5 kg N ha-1). Average rice yields in the RF(5.93 t ha-1) rotation were significantly lower than those in the rotations with winter crops(7.20–7.48 t ha-1)under the N0 treatment, suggesting that incorporation of straw might be more effective for increasing soil N than winter fallow. The rice yield differences among the rotations varied by year with the N input. In general, the grain yields in the RP and RO–G rotations –were respectively 11.6–28.5% and 14.80–37.19% higher than those in the RF in plots with N applied. Increasing the N rate may have tended to minimize the average yield gap between the RF and the other rotations; the yield gaps were 18.55%, 4.14%, and 0.23% in N0, N1, and N2, respectively. However, the N recovery efficiency in the RF was significantly lower than that in other rotations, except for 2015 under both N1 and N2 rates, a finding that implies a large amount of chemical N loss. No significant differences in nitrogen agronomic efficiency(NAE) and physiological efficiency(NPE) were found between the rotations with legume(RC–G) and non–legume(RO and RW) winter crops, a result that may be due partly to straw incorporation. For this reason, we concluded that the return of straw could reduce differences in N use efficiency between rotations with and without legume crops. The degree of synchrony between the crop N demand and the N supply was evaluated by comparison of nitrogen balance degree(NBD) values. The NBD values in the RP and RW were significantly lower than those in the other rotations under both N1 and N2 rates. Thus,in view of the higher grain yield in the RP compared to the RW under the N1 rate, the RP rotation might be a promising practice with comparable grain yield and greater N use efficiency under reduced N input relative to the other rotations. The primary yield components of the RF and RP were identified as number of panicles m-2 and numbers of kernels panicle-1, respectively. The NAE and NPE were positively correlated with harvest index, possibly providing a useful indicator for evaluating N use efficiency. | Song Chen Shaowen Liu Xi Zheng Min Yin Guang Chu Chunmei Xu Jinxiang Yan Liping Chen Danying Wang Xiufu Zhang | 2018 | The Crop Journal2018，6，6： | 13 |
| 8 | Allergy-related Evidences in Relation to Serum IgE:Data from the China State Key Laboratory of Respiratory Disease,2008-2013显示文摘Objective To investigate the serum total IgE(tlgE) and specific IgE(slgE) to common allergens among allergic patients in Guangzhou,China.Methods 7 085 patients were examined for tlgE and slgE to 15 allergens,based on the protocols of reversed enzyme allergosorbent test and the sandwich enzyme-linked immunosorbent assay.Results 3 758(53.04%) patients tested positive for tlgE,and 4 640(65.49%) for slgE.Der pteronyssinus,Der farinae,eggs,and cow's milk were the most common allergens leading to higher positive rates of slgE responses.Several peaks of sensitization were:Der pteronyssinus,Der farinae,and Blomia tropicalis at age 10-12;cow's milk at age below 3;eggs at age 4-6.The mean level and positive rate of tlgE tended to increase in subjects sensitized to more allergens.Sensitization to Der pteronyssinus(OR,1.6;P<0.05),Der farinae(OR,1.5;P<0.05),Blomia tropicalis(OR,1.4;P<0.05),Blattella germanica(OR,1.5;P<0.05),cow's milk(OR,1.3;P<0.05),and soy beans(OR,2.0;P<0.05) were independently correlated with allergy-related conditions in preliminary diagnosis.Conclusion The major allergens in Guangzhou include Der pteronyssinus,Der farinae,cow's milk,and eggs.Sensitization to these allergens appears to be predictors of allergy-related disorder. | SUN Bao Qing CHEN De Hui ZHENG Pei Yan HUANG Hui Min LUO Wen Ting ZENG Guang Qiao ZHANG Xiao Wen | 2014 | Biomedical and Environmental Sciences2014，27，7： | 11 |
| 9 | Deep learning applied to two-dimensional color Doppler flow imaging ultrasound images significantly improves diagnostic performance in the classification of breast masses:a multicenter study显示文摘Background:The current deep learning diagnosis of breast masses is mainly reflected by the diagnosis of benign and malignant lesions.In China,breast masses are divided into four categories according to the treatment method:inflammatory masses,adenosis,benign tumors,and malignant tumors.These categorizations are important for guiding clinical treatment.In this study,we aimed to develop a convolutional neural network(CNN)for classification of these four breast mass types using ultrasound(US)images.Methods:Taking breast biopsy or pathological examinations as the reference standard,CNNs were used to establish models for the four-way classification of 3623 breast cancer patients from 13 centers.The patients were randomly divided into training and test groups(n=1810 vs.n=1813).Separate models were created for two-dimensional(2D)images only,2D and color Doppler flow imaging(2D-CDFI),and 2D-CDFI and pulsed wave Doppler(2D-CDFI-PW)images.The performance of these three models was compared using sensitivity,specificity,area under receiver operating characteristic curve(AUC),positive(PPV)and negative predictive values(NPV),positive(LR+)and negative likelihood ratios(LR-),and the performance of the 2D model was further compared between masses of different sizes with above statistical indicators,between images from different hospitals with AUC,and with the performance of 37 radiologists.Results:The accuracies of the 2D,2D-CDFI,and 2D-CDFI-PW models on the test set were 87.9%,89.2%,and 88.7%,respectively.The AUCs for classification of benign tumors,malignant tumors,inflammatory masses,and adenosis were 0.90,0.91,0.90,and 0.89,respectively(95%confidence intervals[CIs],0.87-0.91,0.89-0.92,0.87-0.91,and 0.86-0.90).The 2D-CDFI model showed better accuracy(89.2%)on the test set than the 2D(87.9%)and 2D-CDFI-PW(88.7%)models.The 2D model showed accuracy of 81.7%on breast masses≤1 cm and 82.3%on breast masses>1 cm;there was a significant difference between the two groups(P<0.001).The accuracy of the CNN classifications for the test set(89.2%)was significantly higher than that of all the radiologists(30%).Conclusions:The CNN may have high accuracy for classification of US images of breast masses and perform significantly better than human radiologists.Trial registration:Chictr.org,ChiCTR1900021375;http://www.chictr.org.cn/showproj.aspx?proj=33139. | Teng-Fei Yu Wen He Cong-Gui Gan Ming-Chang Zhao Qiang Zhu Wei Zhang Hui Wang Yu-Kun Luo Fang Nie Li-Jun Yuan Yong Wang Yan-Li Guo Jian-Jun Yuan Li-Tao Ruan Yi-Cheng Wang Rui-Fang Zhang Hong-Xia Zhang Bin Ning Hai-Man Song Shuai Zheng Yi Li Yang Guang | 2021 | Chinese Medical Journal2021，，4： | 11 |

| 14 | Autophagy activation by Jiang Zhi Granule protects against metabolic stress-induced hepatocyte injury显示文摘AIM To elucidate the potential role of autophagy and the protective effects of Jiang Zhi Granule(JZG) in metabolic stress-induced hepatocyte injury.METHODS An in vitro and in vivo approach was used in this study. Hep G2 cells were incubated in culture medium containing palmitate(PA; 0, 0.1, 0.2, 0.3, 0.4 or 0.5 mmol/L) and treated with or without JZG(100 μg/m L) for 24 h or 48 h, and the progression of autophagy was visualized by stable fluorescence-expressing cell lines LC3 and p62. Western blot analyses were performed to examine the expression of LC3-Ⅱ/LC3-Ⅰ, p62, m TOR and PI3 K, while mitochondrial integrity and oxidative stress were observed by fluorescence staining of JC-1 and reactive oxygen species. C57 BL/6 mice were divided into three groups: control group(n = 10), high fat(HF) group(n = 13) and JZG group(n = 13); and, histological staining was carried out to detect inflammation and lipid content in the liver.RESULTS The cell trauma induced by PA was aggravated in a dose-and time-dependent manner, and hepatic function was improved by JZG. PA had dual effects on autophagy by activating autophagy induction and blocking autophagic flux. The PI3 K-AKT-m TOR signaling pathway and the fusion of isolated hepatic autophagosomes and lysosomes were critically involved in this process. JZG activated autophagy progression by either induction of autophagosomes or co-localization of autophagosomes and lysosomes as well as degradation of autolysosomes to protect against PA-induced hepatocyte injury, and protected mitochondrial integrity against oxidative stress in PA-induced mitochondrial dysfunction. In addition, JZG ameliorated lipid droplets and inflammation induced by HF diet in vivo, leading to improved metabolic disorder and associated liver injury in a mouse model of non-alcoholic fatty liver disease(NAFLD).CONCLUSION Metabolic stress-induced hepatocyte injury exhibited dual effects on autophagy and JZG activated the entire process, resulting in beneficial effects in NAFLD. | Yi-Yuan Zheng Miao Wang Xiang-Bing Shu Pei-Yong Zheng Guang Ji | 2018 | World Journal of Gastroenterology2018，24，9： | 8 |
| 15 | Distribution characteristics of poly-and perfluoroalkyl substances in the Yangtze River Delta显示文摘In this work, a method was developed and optimized for the analysis of polyfluoroalkyl and/or perfluoroalkyl substances(PFASs) content in surface water and sediment samples with high instrumental response and good separation. Surface water and sediment samples were collected from the Yangtze River Delta(YRD) to analyze the distribution characteristics of perfluoroalkyl carboxylic acids(PFCAs), perfluoroalkane sulfonic acids(PFSAs), perfluoroalkyl phosphonic acids(PFPAs), perfluoroalkyl phosphinic acids(PFPiAs), and polyfluoroalkyl phosphoric acid diesters(di PAPs). The results showed that the total concentrations of PFCAs and PFSAs in YRD varied from 31 to 902 ng/L. PFCAs(≥ 11 carbons) and PFSAs(≥ 10 carbons atoms) were not detected in any surface water samples. The mean concentrations of all PFCAs and PFSAs in surface water from the sampling areas decreased in the following order:Yangtze river(191 ng/L) ≈ Taihu lake(189 ng/L) > Huangpu river(122 ng/L) ≈ Qiantang river(120 ng/L) > Jiaxing urban river(100 ng/L). Strong significant(p < 0.05) correlations between the concentrations of many of the compounds were found in the sampling areas, suggesting a common source for these compounds. Only perfluorooctanoic acid(PFOA) was observed in all sediment samples, at concentrations varying from 0.02 to 1.35 ng/g. Finally, detection rates of two di PAPs were only 8% and 10%, respectively and the concentration of di PAPs was two to three times lower compared to PFCAs and PFSAs. | Binghui Zheng Xiaolei Liu Rui Guo Qing Fu Xingru Zhao Shanjun Wang Sheng Chang Xing Wang Mengjiao Geng Guang Yang | 2017 | Journal of Environmental Sciences2017，29，11： | 8 |
| 16 | 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 |
| 17 | Transarterial chemoembolization with PD-(L)1 inhibitors plus molecular targeted therapies for hepatocellular carcinoma(CHANCE001)显示文摘There is considerable potential for integrating transarterial chemoembolization(TACE),programmed death-(ligand)1(PD-[L]1)inhibitors,and molecular targeted treatments(MTT)in hepatocellular carcinoma(HCC).It is necessary to investigate the therapeutic efficacy and safety of TACE combined with PD-(L)1 inhibitors and MTT in real-world situations.In this nationwide,retrospective,cohort study,826 HCC patients receiving either TACE plus PD-(L)1 blockades and MTT(combination group,n=376)or TACE monotherapy(monotherapy group,n=450)were included from January 2018 to May 2021.The primary endpoint was progression-free survival(PFS)according to modified RECIST.The secondary outcomes included overall survival(OS),objective response rate(ORR),and safety.We performed propensity score matching approaches to reduce bias between two groups.After matching,228 pairs were included with a predominantly advanced disease population.Median PFS in combination group was 9.5 months(95%confidence interval[CI],8.4-11.0)versus 8.0 months(95%CI,6.6-9.5)(adjusted hazard ratio[HR],0.70,P=0.002).OS and ORR were also significantly higher in combination group(median OS,19.2[16.1-27.3]vs.15.7 months[13.0-20.2];adjusted HR,0.63,P=0.001;ORR,60.1%vs.32.0%;P<0.001).Grade 3/4 adverse events were observed at a rate of 15.8%and 7.5%in combination and monotherapy groups,respectively.Our results suggest that TACE plus PD-(L)1 blockades and MTT could significantly improve PFS,OS,and ORR versus TACE monotherapy for Chinese patients with predominantly advanced HCC in real-world practice,with an acceptable safety profile. | Hai-Dong Zhu Hai-Liang Li Ming-Sheng Huang Wei-Zhu Yang Guo-Wen Yin Bin-Yan Zhong Jun-Hui Sun Zhi-Cheng Jin Jian-Jian Chen Nai-Jian Ge Wen-Bin Ding Wen-Hui Li Jin-Hua Huang Wei Mu Shan-Zhi Gu Jia-Ping Li Hui Zhao Shu-Wei Wen Yan-Ming Lei Yu-Sheng Song Chun-Wang Yuan Wei-Dong Wang Ming Huang Wei Zhao Jian-Bing Wu Song Wang Xu Zhu Jian-Jun Han Wei-Xin Ren Zai-Ming Lu Wen-Ge Xing Yong Fan Hai-Lan Lin Zi-Shu Zhang Guo-Hui Xu Wen-Hao Hu Qiang Tu Hong-Ying Su Chuan-Sheng Zheng Yong Chen Xu-Ya Zhao Zhu-Ting Fang Qi Wang Jin-Wei Zhao Ai-Bing Xu Jian Xu Qing-Hua Wu Huan-Zhang Niu Jian Wang Feng Dai Dui-Ping Feng Qing-Dong Li Rong-Shu Shi Jia-Rui Li Guang Yang Hai-Bin Shi Jian-Song Ji Yu-E Liu Zheng Cai Po Yang Yang Zhao Xiao-Li Zhu Li-Gong Lu Gao-Jun Teng | 2023 | Signal Transduction and Targeted Therapy2023，8，3： | 7 |
| 18 | Garciesculenxanthone B induces PINK1-Parkin-mediated mitophagy and prevents ischemia-reperfusion brain injury in mice显示文摘Mitophagy is a selective form of autophagy involving the removal of damaged mitochondria via the autophagy-lysosome pathway.PINK1-Parkin-mediated mitophagy is one of the most important mechanisms in cardiovascular disease,cerebral ischemia-reperfusion(I/R)injury,and neurodegenerative diseases.In this study we conducted an image-based screening in YFP-Parkin HeLa cells to discover new mitophagy regulators from natural xanthone compounds.We found that garciesculenxanthone B(GeB),a new xanthone compound from Garcinia esculenta,induced the formation of YFP-Parkin puncta,a well known mitophagy marker.Furthermore,treatment with GeB dose-dependently promoted the degradation of mitochondrial proteins Tom20,Tim23,and MFN1 in YFP-Parkin HeLa cells and SH-SY5Y cells.We revealed that GeB stabilized PINK1 and triggered Parkin translocation to the impaired mitochondria to induce mitophagy,and these effects were abolished by knockdown of PINK1.Finally,in vivo experiments demonstrated that GeB partially rescued ischemia-reperfusion-induced brain injury in mice.Taken together,our findings demonstrate that the natural compound GeB can promote the PINK1-Parkin-mediated mitophagy pathway,which may be implicated in protection against I/R brain injury. | Man Wu Guang Lu Yuan-zhi Lao Hong Zhang Dan Zheng Zhao-qing Zheng Juan Yi Qian Xiang Li-ming Wang Hong-sheng Tan Hua Zhou Han-ming Shen Hong-xi Xu | 2021 | Acta Pharmacologica Sinica2021，42，2： | 7 |
| 19 | Preparation and Characterization of Microencapsulated Hexadecane Used for Thermal Energy Storage显示文摘Polyurea microcapsules about 2.5μm in diameter containing phase change material for thermal energy storage application were synthesized and characterized by interfacial polycondensation method with toluene-2,4-diisocyanate and ethylenediamine as monomers in an emulsion system. Hexadecane was used as a phase change material and OP, which is nonionic surfactant, and used as an emulsifier. The chemical structure and thermal behavior of the microcapsules were investigated by FTIR and thermal analysis respectively. The results show encapsulated hexadecane has a good potential as a solar energy storage material. | Guang Long ZOU Zhi Cheng TAN Xiao Zheng LAN Li Xian SUN Tao ZHANG | 2004 | Chinese Chemical Letters2004，15，6： | 7 |
