| 3 | First report of the South American tomato leafminer, Tuta absoluta (Meyrick), in China显示文摘Tuta absoluta(Meyrick) originated in South America and is one of the most serious pests of tomatoes. It is also known to attack other solanaceous crops, including potato, eggplant, pepper, tobacco, and weedy species such as black nightshade. After accidental introduction into Spain in 2006, this pest spread rapidly throughout Afro-Eurasia and has become a major threat to tomato production worldwide. Here, we report the first record of T. absoluta as an invasive pest in China. It was found in tomato fields in Ili Kazakg Autonomous Prefecture, Xinjiang Uygur Autonomous Region(Ili, Xinjiang), China, and its occurrence was confirmed by both morphological and molecular approaches. In Ili, T. absoluta has been found to attack eggplant, potato, and black nightshade. We found the larvae generally mining and feeding on leaves and boring into tomato fruits, with multiple larvae sometimes observed in a single fruit. Its infestation levels differ among the tomato fields and host species. In all of the surveyed tomato fields, T. absoluta infested 100% of plants. In some of the fields, up to 90% of the eggplant and 100% of the potato plants were infested. Since no natural enemies were found under field conditions, suitable management practices are urgently needed to stop the further spread of this destructive pest in China. | ZHANG Gui-fen MA De-ying WANG Yu-sheng GAO You-hua LIU Wan-xue ZHANG Rong FU Wen-jun XIAN Xiao-qing WANG Jun KUANG Meng WAN Fang-hao | 2020 | Journal of Integrative Agriculture2020,19,7: | 12 |

| 5 | Interfacial Properties Modification of Carbon Fiber/Polyarylacetylene Composites显示文摘This work was dedicated to performing surface oxidation and coating treatments on carbon fibers (CF) and investigating the changes of fiber surface properties after these treatments, including surface composition, relative volume of functional groups, and sur- face topography with X-ray photoelectron spectroscopy (XPS) and atom force microscopy (AFM) technology. The results show that, after oxidation treatments, interfacial properties between CF and non-polar polyarylacetylene (PAA) resin are remarkably modified by removing weak surface layers and increasing fiber surface roughness. Coating treatment by high char phenolic resin solution after oxida- tion makes interface of CF/PAA composites to be upgraded and the interfacial properties further bettered. | FU Hong-jun MA Chong-qi KUANG Nai-hang LUAN Shi-lin | 2007 | Chinese Journal of Aeronautics2007,20,2: | 8 |
| 6 | Exosomes derived from 3D-cultured MSCs improve therapeutic effects in periodontitis and experimental colitis and restore the Th17 cell/Treg balance in inflamed periodontium显示文摘Although mesenchymal stem cell-derived exosomes(MSC-exos)have been shown to have therapeutic effects in experimental periodontitis,their drawbacks,such as low yield and limited efficacy,have hampered their clinical application.These drawbacks can be largely reduced by replacing the traditional 2D culture system with a 3D system.However,the potential function of MSC-exos produced by 3D culture(3D-exos)in periodontitis remains elusive.This study showed that compared with MSC-exos generated via 2D culture(2D-exos),3D-exos showed enhanced anti-inflammatory effects in a ligature-induced model of periodontitis by restoring the reactive T helper 17(Th17)cell/Treg balance in inflamed periodontal tissues.Mechanistically,3D-exos exhibited greater enrichment of miR-1246,which can suppress the expression of Nfat5,a key factor that mediates Th17 cell polarization in a sequence-dependent manner.Furthermore,we found that recovery of the Th17 cell/Treg balance in the inflamed periodontium by the local injection of 3D-exos attenuated experimental colitis.Our study not only showed that by restoring the Th17 cell/Treg balance through the miR-1246/Nfat5 axis,the 3D culture system improved the function of MSC-exos in the treatment of periodontitis,but also it provided a basis for treating inflammatory bowel disease(IBD)by restoring immune responses in the inflamed periodontium. | Yong Zhang Jiayao Chen Haijun Fu Shuhong Kuang Feng He Min Zhang Zongshan Shen Wei Qin Zhengmei Lin Shuheng Huang | 2021 | International Journal of Oral Science2021,13,4: | 4 |

| 9 | Patterns of gas hydrate accumulation in mass transport deposits related to canyon activity: Example from Shenhu drilling area in the South China Sea显示文摘Since 2017, a plenty of gas hydrates have been drilled in a new area of Shenhu, and good heterogeneity has been found throughout the spatial distribution of the reservoir. After distinguishing different sedimentary sequence types and matching their formation with slope deposition settings, this study proposes three mass transport deposit(MTD) patterns related to canyon activity that occurred contemporaneously or epigenetically with it: well preserved MTDs, MTDs eroded by canyon migration, and MTDs dislocated by contemporaneous faults. Based on seismic reflection characteristics, this study proposed methods of quantitatively analyzing sedimentary factors,such as measuring the turbidities flow rate in the canyon, and results are interpreted with respect to canyon activity. Combining the above parameters and their relationship with gas hydrate accumulation, fine-grained seals overlapping coarse MTDs reservoirs are found to be indispensable to gas hydrate accumulation, as they prevent the release of free gas. Based on grain size data of hydrate samples from drilling wells, multi-layered gas hydrate reservoirs capped by fine-grained sediments and overlapping mud show favorable hydrate-bearing prospects. The release of gas hydrates, however, is mostly caused by the lack of mud sealing in relation to canyon activity, such as turbidities flow erosion and contemporaneous fault breaking. Canyon migration with respect to MTDs may be the actual cause of erosion of overlapping syn-sedimentary layers, and high bottom flows may contribute to an increase in the release of free gas. It is believed that contemporaneous faults caused by unstable canyon walls may break the muddy over layers and decrease the accumulation pressure of gas hydrate bearing.Thus, according to the sedimentary characteristics of MTDs and the hydrate accumulation process, three responding accumulation or releasing patterns are proposed, which respond to the different types of MTDs distinguished above: a well-preserved MTD accumulation pattern; a canyon migration eroded MTD release pattern; and a micro-contemporaneous fault dislocated MTD release pattern. | Chao Fu Shengli Li Xinghe Yu Jinqiang Liang Zenggui Kuang Yulin He Lina Jin | 2019 | Acta Oceanologica Sinica2019,38,5: | 3 |
| 10 | Early colon cancer within a diverticulum treated by magnifying chromoendoscopy and laparoscopy显示文摘We report a unique case of intramucosal carcinoma in a tubulovillous adenoma arising from a single diverticulum.Endoscopic mucosal resection(EMR)was carried out successfully and completely with the assistance of laparoscopy.A 71-year-old man was admitted to our hospital because of melena and anemia.Emergent colonoscopy showed diverticulosis in the right-sided colon.However,endoscopy could not exactly detect the bleeding site.A flat elevated polyp was found within a single diverticulum located in the descending colon and diagnosed as an intramucosal carcinoma,as magnifying chromoendoscopy revealed a type Ⅳ pit pattern.As his diverticular bleeding repeated,a rightsided hemicolectomy was decided for treatment,the polyp within the diverticulum was also completely removed by EMR with the assistance of laparoscopy.Although a colonic perforation was detected immediately after EMR,the perforation was closed with endoclips intraluminally and also repaired laparoscopically from the serosal side.Histologically,the resected lesion was an intramucosal well-differentiated adenocarcinoma and the surgical margin was free of tumor. | Kuang I Fu Yukihiro Hamahata Yasunobu Tsujinaka | 2010 | World Journal of Gastroenterology2010,16,12: | 3 |
| 11 | A detachable coating of cholesterol-anchored PEG improves tumor targeting of cell-penetrating peptide-modified liposomes显示文摘Cell-penetrating peptides(CPPs)have been widely used to enhance the membrane transloca-tion of various carriers for many years,but the non-specificity of CPPs seriously limits their utility in vivo.In this study,cholesterol-anchored,reduction-sensitive PEG(first synthesized by our laboratory)was applied to develop a co-modified liposome with improved tumor targeting.Following optimization of the formulation,the in vitro and in vivo properties of the co-modified liposome were evaluated.The co-modified liposome had a much lower cellular uptake and tumor spheroid uptake,but a much higher tumor accumulation compared to CPP-modified liposome,indicating the non-specific penetration of CPPs could be attenuated by the outer PEG coating.With the addition of exogenous reducing agent,both the in vitro and in vivo cellular uptake was markedly increased,demonstrating that the reduction-sensitive PEG coating achieved a controllable detachment from the surface of liposomes and did not affect the penetrating abilities of CPPs.The present results demonstrate that the combination of cholestervsitive PEG and CPPs is an ideal alternative for the application of CPP-modified carriers in vivo. | Jie Tang Li Zhang Han Fu Qifang Kuang Huile Gao Zhirong Zhang Qin Hen | 2014 | Acta Pharmaceutica Sinica B2014,4,1: | 3 |
| 12 | Trichosanthin inhibits T cell activation by interfering with the recruitment of ZAP-70 to CD3 ζchain显示文摘Plant protein Trichosanthin (Tk) has been shown in our previous experiments to suppress antigenic response of T cells. Here we explored its inhibitory mechanisms on the proliferation of human Jurkat leukemia T cell triggered by anti-CD3 McAb. By examination of tyrosine phosphorylation of cell lysate, we were able to show that Tk could interfere with the PTK-related activity in the TCR/CD3initiated signal transduction in addition to blocking the phosphorylation of PKC. As shown in our experiment,the expression intensity of ZAP-70, a kind of protein tyrosine kinase, was not changed but its phosphorylation could be inhibited. When physical link between CD3(chain and ZAP-70 was further examined by using coimmunoprecipitation after pluse-treatment of the cell line with Tk, the anti-CD3 McAb-induced recruitment of ZAP70 to CD3 ζ chain was observed to be blocked in some extent. This may account for, at least in part, how Trichosanthin was able to inhibit the TCR-triggered T cell proliferation. | HONG JIAN SAI LI FU ZHONG YI SHEN PEI HUA LU KUANG YEN CHOU (Shanghai Institute of Immunology, Shanghai Second Medical University, Shanghai China) | 1998 | Cell Research1998,8,1: | 3 |
| 13 | Molecular Cloning and Characterization of Carnation EBF1 Gene During Flower Senescence and upon Ethylene Exposure and Sugar显示文摘A cDNA clone encoding a putative EBF-like protein (DCEBF1) was obtained from total RNA isolated from senescing carnation (Dianthus caryophyllus L.) petals using reverse transcription PCR and rapid-amplification of cDNA ends techniques. The cDNA contained an open reading frame of 1 878 bp corresponding to 625 amino acids. Results of Northern blot indicated DCEBF1 expression was enhanced by endogenous and exogenous ethylene, and was inhibited by STS in petals and ovaries. Upon wounding treatment, DCEBF1 showed a quick increase in mRNA accumulation which was positively correlated with the increase in ethylene production. The levels of DCEBF1 mRNA increased in both petals and ovaries by sucrose treatment compared with the control. | FU Zhao-di WANG Hui-nan LIU Juan-xu ZENG Hong-xue ZHANG Jiao KUANG Xiao-cong YU Yi-xun | 2011 | Agricultural Sciences in China2011,10,12: | 3 |
| 14 | Different endometrial preparation protocols yield similar pregnancy outcomes for frozen-thawed embryo transfer in patients with advanced endometriosis显示文摘Objective To explore the different endometrial preparation for frozen-thawed embryo transfer(FET) in women with advanced endometriosis(EMS).Methods The pregnancy outcomes of patients with advanced EMS(542 cycles), who were prepared for FET, were retrospectively assessed. Included patients underwent a total of 233 FET cycles(180 patients) using natural cycle(NC), a total of 142 FET cycles(115 patients) using letrozole(LE) ovulation induction, and a total of 167 FET cycles(137 patients) using hormonal replacement treatment(HRT) for endometrial preparation.Results There were no significant diffenences in the clinical pregnancy rate(LE:49.30%, NC: 50.21%, and HRT: 43.11%, P=0.343), the implantation rate(LE: 29.26%,NC: 36.03%, and HRT: 29.55%, P=0.084), and the live birth rate(LE: 38.02%, NC:39.11%, and HRT: 35.33%, P=0.648) among the three groups. No statistically significant differences were observed in the ongoing pregnancy rate, the miscarriage rate,and the pregnancy complication rate. The single birth weight in patients using NCFET was lower than that in patients using HRT-FET(P=0.044) and a higher twin birth weight in patients using LE-FET were observed compared with other groups(P=0.022).The rate of birth weight <2 500 g was also higher in the NC-FET group than in other groups. No congenital birth defects were found in the three groups.Conclusion Different endometrial preparation protocols without ultra-long Gn RH-adown-regulation for FET yield similar pregnancy outcomes in patients with EMS. A tailored endometrial preparation protocol should be recommended according to different patients?situation. | Hai-yan GUO Yun WANG Qiu-ju CHEN Wei-ran CHAI Li-hua SUN Ai AI Yong-lun FU Qi-feng LYU Yan-ping KUANG | 2016 | Journal of Reproduction and Contraception2016,27,1: | 3 |
| 15 | The genome and gene editing system of sea barleygrass provide a novel platform for cereal domestication and stress tolerance studies显示文摘The tribe Triticeae provides important staple cereal crops and contains elite wild species with wide geneticdiversity and high tolerance to abiotic stresses. Sea barleygrass (Hordeum marinum Huds.), a wildTriticeae species, thrives in saline marshlands and is well known for its high tolerance to salinity and waterlogging. Here, a 3.82-Gb high-quality reference genome of sea barleygrass is assembled de novo, with 3.69Gb (96.8%) of its sequences anchored onto seven chromosomes. In total, 41 045 high-confidence (HC)genes are annotated by homology, de novo prediction, and transcriptome analysis. Phylogenetics, nonsynonymous/synonymous mutation ratios (Ka/Ks), and transcriptomic and functional analyses provide genetic evidence for the divergence in morphology and salt tolerance among sea barleygrass, barley, andwheat. The large variation in post-domestication genes (e.g. IPA1 and MOC1) may cause interspecies differences in plant morphology. The extremely high salt tolerance of sea barleygrass is mainly attributed tolow Na+ uptake and root-to-shoot translocation, which are mainly controlled by SOS1, HKT, and NHX transporters. Agrobacterium-mediated transformation and CRISPR/Cas9-mediated gene editing systems weredeveloped for sea barleygrass to promote its utilization for exploration and functional studies of hubgenes and for the genetic improvement of cereal crops. | Liuhui Kuang Qiufang Shen Liyang Chen Lingzhen Ye Tao Yan Zhong-Hua Chen Robbie Waugh Qi Li Lu Huang Shengguan Cai Liangbo Fu Pengwei Xing Kai Wang Jiari Shao Feibo Wu Lixi Jiang Dezhi Wu Guoping Zhang | 2022 | Plant Communications2022,3,5: | 2 |
| 16 | Clomiphene Citrate as An Adjuvant to hMG Stimulation of the Ovaries in Mid-to-late Follicular Phase and Subsequently Pregnancy Outcome of Frozen-thawed Embryo Transfers显示文摘Objective To compare the results of a novel regimen of human menopausal gonadotrophin (hMG) in combination with clomiphene citrate (CC) in mid-to-late follicular phase with those of a short protocol of GnRH agonist (GnRHa) and hMG used for IVF. Methods In the retrospective study, 842 patients undergoing IVF were collected and classified into two groups: hMG in combination with CC in mid-to-late follicular phase (group A, n=319) and short protocol of GnRHa-hMG (group B, n=523). The main outcome measures were ovarian responses in stimulation cycles and pregnancy outcomes in subsequent frozen-thawed embryo transfer (FET) cycles. Results In group A, the serum LH concentration on day 8-10 was similar with that on the day of hCG administration (2.43 ± 1.92 IU vs 2.51 ± 2.05 IU). The number of mature follicles and oocytes retrieved was significantly lower in group A than in group B while the fertilization rate and the cleavage rate were comparable. The clinical pregnancy rate (47.79% vs 48.04%), the implantation rate (32.49% vs 33.11%) and the cumulative pregnancy rate (58.09% vs 60.22%) were respectively similar in group A and group B. Conclusion hMG in combination with CC in mid-to-late follicular phase results in the same pregnancy outcome as short protocol. The novel protocol may take the advantage of eliminating the occurrence of a premature endogenous LH surge. | Yan KANG Qing-qing HONG Wei-ran CHAI Yong-lun FU Ai AI Qiu-ju CHEN Yan-ping KUANG | 2013 | Journal of Reproduction and Contraception2013,24,1: | 2 |
| 17 | Review of 4Pi Fluorescence Nanoscopy显示文摘Since the 1990s,continuous technical and scientific advances have defied the diffraction limit in microscopy and enabled three-dimensional(3D)super-resolution imaging.An important milestone in this pursuit is the coherent utilization of two opposing objectives(4Pi geometry)and its combination with superresolution microscopy.Herein,we review the recent progress in 4Pi nanoscopy,which provides a 3D,non-invasive,diffraction-unlimited,and isotropic resolution in transparent samples.This review includes both the targeted and stochastic switching modalities of 4Pi nanoscopy.The schematics,principles,applications,and future potential of 4Pi nanoscopy are discussed in detail. | Xiang Hao Yiming Li Shuang Fu Yanghui Li Yingke Xu Cuifang Kuang Xu Liu | 2022 | Engineering2022,8,4: | 2 |
| 18 | Notch1 Drives the Formation and Proliferation of Intrahepatic Cholangiocarcinoma显示文摘The molecular mechanisms underlying the development of intrahepatic cholangiocarcinoma(ICC)are not clear yet.In this study,we investigated the involvement of Notch1 in the development of ICC.The cDNA microarray analysis showed that Notch1 expression was higher in ICC tissues than in normal biliary epithelial cells.Stable transfection of Notchl receptor intracellular domain(NICD1)by hydrodynamic tail vein injection induced ICC formation in mice.Western blotting confirmed that Notchl signaling was activated in human ICC cell lines and mouse ICC tissues.Silencing Notchl with specific short interfering RNA(siRNA)inhibited the proliferation of ICC cells.Flow cytometry and Western blotting indicated that apoptosis was induced in Notchl-silenced ICC cells compared with controls.Additionally,Notchl silencing was associated with the inhibition of hairy and enhancer of split-1(Hes1)and activation of the phosphatase and tensin homolog(PTEN)/p53 pathway.Taken together,these data suggest that Notchl drives ICC formation and proliferation;downregulation of Notchl induces apoptosis in ICC cells;Notchl signaling may serve as a novel therapeutic target for the treatment of ICC. | Jun GUO Wen FU Ming XIANG Yu ZHANG Ke ZHOU Chuan-rui XU Lei LI Dong KUANG Feng YE | 2019 | Current Medical Science2019,39,6: | 2 |
