| 2 | Transplantation of collagen scaffold with autologous bone marrow mononuclear cells promotes functional endometrium reconstruction via downregulating ΔNp63 expression in Asherman's syndrome显示文摘Asherman's syndrome(AS) is a common disease that presents endometrial regeneration disorder. However, little is known about its molecular features of this aregenerative endometrium in AS and how to reconstruct the functioning endometrium for the patients with AS. Here, we report that ΔNp63 is significantly upregulated in residual epithelial cells of the impaired endometrium in AS; the upregulated-ΔNp63 induces endometrial quiescence and alteration of stemness. Importantly, we demonstrate that engrafting high density of autologous bone marrow mononuclear cells(BMNCs) loaded in collagen scaffold onto the uterine lining of patients with AS downregulates ΔNp63 expression, reverses ΔNp63-induced pathological changes, normalizes the stemness alterations and restores endometrial regeneration. Finally, five patients achieved successful pregnancies and live births. Therefore, we conclude that ΔNp63 is a crucial therapeutic target for AS. This novel treatment significantly improves the outcome for the patients with severe AS. | Guangfeng Zhao Yun Cao Xianghong Zhu Xiaoqiu Tang Lijun Ding Haixiang Sun Juan Li Xinan Li Chenyan Dai Tong Ru Hui Zhu Jingjie Lu Caimei Lin Jingmei Wang Guijun Yan Huiyan Wang Lei Wang Yimin Dai Bin Wang Ruotian Li Jianwu Dai Yan Zhou Yali Hu | 2017 | Science China(Life Sciences)2017，60，4： | 39 |
| 3 | Prognostic value of systemic immune.inflammation index in patients with gastric cancer显示文摘Background:Inflammation-based indexes have been used to predict survival and recurrence in cancer patients.Systemic immune-inflammation index(Sll) was reported to be associated with prognosis in some malignant tumors.In the present study,we aimed to explore the association between Sll and the prognosis of patients with gastric cancer.Methods:We retrospectively analyzed data from 444 gastric cancer patients who underwent gastrectomy at the First Affiliated Hospital of Sun Yat-sen University between January 1994 and December 2005.Preoperative Sll was calculated.The Chi square test or Fisher's exact test was used to determine the relationship between preoperative Sll and clinicopathologic characteristics.Overall survival(OS) rates were estimated using the Kaplan-Meier method,and the effect of Sll on OS was analyzed using the Cox proportional hazards model.Receiver operating characteristic(ROC)curves were used to compare the predictive ability of Sll,NLR,and PLR.Results:Sll equal to or higher than 660 was significantly associated with old age,large tumor size,unfavorable Borrmann classification,advanced tumor invasion,lymph node metastasis,distant metastasis,advanced TNM stage,and high carcino-embryonic antigen level,high neutrophil-lymphocyte ratio,and high platelet-lymphocyte ratio(all P<0.05).High Sll was significantly associated with unfavorable prognosis(P<0.001) and Sll was an independent predictor for OS(P=0.015).Subgroups analysis further showed significant associations between high Sll and short OS in stage Ⅰ,Ⅱ,Ⅲ subgroups(all P<0.05).Sll was superior to NLR and PLR for predicting OS in patients with gastric cancer.Conclusion:Preoperative Sll level is an independent prognostic factor for OS in patients with gastric cancer. | Kang Wang Feiyu Diao Zhijun Ye Xinhua Zhang Ertao Zhai Hui Ren Tong Li Hui Wu Yulong He Shirong Cai Jianhui Chen | 2017 | Chinese Journal of Cancer2017，36，9： | 30 |
| 4 | Air pollution characteristics and their relationship with emissions and meteorology in the Yangtze River Delta region during 2014–2016显示文摘With rapid economic growth and urbanization, the Yangtze River Delta(YRD) region in China has experienced serious air pollution challenges. In this study, we analyzed the air pollution characteristics and their relationship with emissions and meteorology in the YRD region during 2014–2016. In recent years, the concentrations of all air pollutants, except O3,decreased. Spatially, the PM2.5, PM10, SO2, and CO concentrations were higher in the northern YRD region, and NO2 and O3 were higher in the central YRD region. Based on the number of non-attainment days(i.e., days with air quality index greater than 100), PM2.5 was the largest contributor to air pollution in the YRD region, followed by O3, PM10, and NO2.However, particulate matter pollution has declined gradually, while O3 pollution worsened.Meteorological conditions mainly influenced day-to-day variations in pollutant concentrations. PM2.5 concentration was inversely related to wind speed, while O3 concentration was positively correlated with temperature and negatively correlated with relative humidity.The air quality improvement in recent years was mainly attributed to emission reductions.During 2014–2016, PM2.5, PM10, SO2, NOx, CO, NH3, and volatile organic compound(VOC)emissions in the YRD region were reduced by 26.3%, 29.2%, 32.4%, 8.1%, 15.9%, 4.5%, and0.3%, respectively. Regional transport also contributed to the air pollution. During regional haze periods, pollutants from North China and East China aggravated the pollution in the YRD region. Our findings suggest that emission reduction and regional joint prevention and control helped to improve the air quality in the YRD region. | Tao Ma Fengkui Duan Kebin He Yu Qin Dan Tong Guannan Geng Xuyan Liu Hui Li Shuo Yang Siqi Ye Beiyao Xu Qiang Zhang Yongliang Ma | 2019 | Journal of Environmental Sciences2019，31，9： | 26 |

| 6 | Isolation and characterization of dengue virus serotype 2 from the large dengue outbreak in Guangdong, China in 2014显示文摘Dengue has been well recognized as a global public health threat,but only sporadic epidemics and imported cases were reported in recent decades in China.Since July 2014,an unexpected large dengue outbreak has occurred in Guangdong province,China,resulting in more than 40000 patients including six deaths.To clarify and characterize the causative agent of this outbreak,the acute phase serum from a patient diagnosed with severe dengue was subjected to virus isolation and high-throughput sequencing(HTS).Traditional real-time RT-PCR and HTS with Ion Torrent PGM detected the presence of dengue virus serotype 2(DENV-2).A clinical DENV-2 isolate GZ05/2014 was obtained by culturing the patient serum in mosquito C6/36 cells.The complete genome of GZ05/2014 was determined and deposited in Gen Bank under the access number KP012546.Phylogenetic analysis based on the complete envelope gene showed that the newly DENV-2 isolate belonged to Cosmopolitan genotype and clustered closely with other Guangdong strains isolated in the past decade.No amino acid mutations that are obviously known to increase virulence or replication were identified throughout the genome of GZ05/2014.The high homology of Guangdong DENV-2 strains indicated the possibility of establishment of local DENV-2 circulation in Guangdong,China.These results help clarify the origin of this epidemic and predict the future status of dengue in China. | ZHAO Hui ZHAO Ling Zhai JIANG Tao LI Xiao Feng FAN Hang HONG Wen Xin ZHANG Yu ZHU Qin YE Qing TONG Yi Gang CAO Wu Chun ZHANG Fu Chun QIN Cheng Feng | 2014 | Science China(Life Sciences)2014，57，12： | 21 |

| 8 | Collagen-binding basic fibroblast growth factor improves functional remodeling of scarred endometrium in uterine infertile women: a pilot study显示文摘Intrauterine adhesion(IUA) is a common cause of uterine infertility and one of the most severe clinical features is endometrial fibrosis namely endometrial scarring for which there are few cures currently. Blocked angiogenesis is the main pathological change in the scarred endometrium. The fibroblast growth factor 2(b FGF), a member of FGF family, is usually applied to promote healing of refractory ulcer and contributes to angiogenesis of tissues. In this study, the sustained-release system of b FGF100 μg was administrated around scarred endometrium guiding by ultrasound every 4 weeks in 18 patients(2–4 times). Results showed that after treatment, the menstrual blood volume, endometrial thickness and the scarred endometrial area were improved.Histological study showed blood vessel density increased obviously. Three patients(3/18) achieved pregnancy over 20 gestational weeks. Therefore, administrating the b FGF surrounding scarred endometrium may provide a new therapeutic approach for the patients with endometrial fibrosis. | Peipei Jiang Xiaoqiu Tang Huiyan Wang Chenyan Dai Jing Su Hui Zhu Minmin Song Jingyu Liu Ziqing Nan Tong Ru Yaling Li Jingmei Wang Jun Yang Bing Chen Jianwu Dai Yali Hu | 2019 | Science China(Life Sciences)2019，62，12： | 16 |
| 9 | Vascular endothelial growth factor: an attractive target in the treatment of hypoxic/ischemic brain injury显示文摘Cerebral hypoxia or ischemia results in cell death and cerebral edema, as well as other cellular reactions such as angiogenesis and the reestablishment of functional microvasculature to promote recovery from brain injury. Vascular endothelial growth factor is expressed in the central nervous system after hypoxic/ischemic brain injury, and is involved in the process of brain repair via the regulation of angiogenesis, neurogenesis, neurite outgrowth, and cerebral edema, which all require vascular endothelial growth factor signaling. In this review, we focus on the role of the vascular endothelial growth factor signaling pathway in the response to hypoxic/ischemic brain injury, and discuss potential therapeutic interventions. | Hui Guo Hui Zhou Jie Lu Yi Qu Dan Yu Yu Tong | 2016 | Neural Regeneration Research2016，11，1： | 15 |
| 10 | Molecular Characterization of Drug-Resistant Beijing Family Isolates of Mycobacterium Tuberculosis from Tianjin,China显示文摘Objective Tuberculosis remains a severe public health issue,and the Beijing family of mycobacterium tuberculosis(M. tuberculosis) is widespread in East Asia,especially in some areas in China,like Beijing and Tianjin.This study aimed at determining the mutation patterns of drug-resistant Beijing strains of M.tuberculosis isolated from Tianjin,China.Methods A total of 822 M.tuberculosis isolates were screened for drug resistance by an absolute concentration method and the genotype was identified by PCR.169 drug-resistant isolates of the Beijing family were analyzed for the potential mutations in the rpoB, katG,inhA promoter region and in rpsL,rrs and embB genes,which are associated with resistance to rifampin(RFP),isoniazid (INH),streptomycin(SM) and ethambutol(EMB) respectively by PCR and DNA sequencing.Results Fifty-eight out of 63 RFP-resistant isolates were found to carry the mutations within the 81-bp RFP resistance determining region(RRDR) of the rpoB gene and the most frequent mutations occurred at codon 531(44.4%),526(28.6%),and 516(7.9%) respectively.16 mutation patterns affecting 12 different codons around the RRDR of rpoB were found.Of 116 INH-resistant isolates,56(48.3%) had the mutation of katG 315(AGC→ACC)(Ser→Thr),3(2.6%) carried S315N(AGC→AAC) and 27(16.0%) had the mutation of inhA-15A→T.84 out of 122 SM-resistant isolates(68.9%) displayed mutations at the codons 43 or 88 with AAG→AGG(Lys→Arg) of the rpsL gene and 22(18.0%) with the mutations at positions 513A→C,516C→T or 905 A→G in the rrs gene.Of 34 EMB-resistant isolates,6 had mutation with M306V(ATG→GTG),3 with M306I(ATG→ATT),1 with M306I(ATG→ATA),1 with D328Y(GAT→TAT),1 with V348L(GTC→CTC),and 1 with G406S(GGC→AGC) in the embB gene.Conclusion These novel findings extended our understanding of resistance-related mutations in the Beijing strains of M.tuberculosis and may provide a scientific basis for development of new strategies for diagnosis and control of tuberculosis in China and other countries where Beijing strains are prevalent. | GUI-LIAN LI DE-FU ZHAO TONG XIE HAN-FANG JU CHENG MU HUI ZHAO XIE-XIU WANG | 2010 | Biomedical and Environmental Sciences2010，23，3： | 14 |

| 16 | Interpretation of breast cancer screening guideline for Chinese women显示文摘Breast cancer is the most common malignant tumor in Chinese women.Early screening is the best way to improve the rates of early diagnosis and survival of breast cancer patients.The peak onset age for breast cancer in Chinese women is considerably younger than those in European and American women.It is imperative to develop breast cancer screening guideline that is suitable for Chinese women.By summarizing the current evidence on breast cancer screening in Chinese women,and referring to the latest guidelines and consensus on breast cancer screening in Europe,the United States,and East Asia,the China Anti-Cancer Association and National Clinical Research Center for Cancer(Tianjin Medical University Cancer Institute and Hospital)have formulated population-based guideline for breast cancer screening in Chinese women.The guideline provides recommendations on breast cancer screening for Chinese women at average or high risk of breast cancer according to the following three aspects:age of screening,screening methods,and screening interval.This article provides more detailed information to support the recommendations in this guideline and to provide more direction for current breast cancer screening practices in China. | Yubei Huang Zhongsheng Tong Kexin Chen Ying Wang Peifang Liu Lin Gu Juntian Liu Jinpu Yu Fengju Song Wenhua Zhao Yehui Shi Hui Li Huaiyuan Xiao Xishan Hao | 2019 | Cancer Biology & Medicine2019，16，4： | 10 |
| 17 | High-performance silicon−graphene hybrid plasmonic waveguide photodetectors beyond 1.55μm显示文摘Graphene has attracted much attention for the realization of high-speed photodetection for silicon photonics over a wide wavelength range.However,the reported fast graphene photodetectors mainly operate in the 1.55μm wavelength band.In this work,we propose and realize high-performance waveguide photodetectors based on bolometric/photoconductive effects by introducing an ultrathin wide silicon−graphene hybrid plasmonic waveguide,which enables efficient light absorption in graphene at 1.55μm and beyond.When operating at 2μm,the present photodetector has a responsivity of ~70 mA/W and a setup-limited 3 dB bandwidth of >20 GHz.When operating at 1.55μm,the present photodetector also works very well with a broad 3 dB bandwidth of >40 GHz(setup-limited)and a high responsivity of ~0.4 A/W even with a low bias voltage of−0.3 V.This work paves the way for achieving highresponsivity and high-speed silicon-graphene waveguide photodetection in the near/mid-infrared ranges,which has applications in optical communications,nonlinear photonics,and on-chip sensing. | Jingshu Guo Jiang Li Chaoyue Liu Yanlong Yin Wenhui Wang Zhenhua Ni Zhilei Fu Hui Yu Yang Xu Yaocheng Shi Yungui Ma Shiming Gao Limin Tong Daoxin Dai | 2020 | Light(Science & Applications)2020，9，1： | 10 |
| 18 | The positive function of selenium supplementation on reducing nitrate accumulation in hydroponic lettuce(Lactuca sativa L.)显示文摘High nitrate(NO_3^- ) in vegetables, especially in leaf vegetables poses threaten to human health. Selenium(Se) is an important element for maintaining human health, and exogenous Se application during vegetable and crop production is an effective way to prevent Se deficiency in human bodies. Exogenous Se shows positive function on plant growth and nutrition uptake under abiotic and/or biotic stresses. However, the influence of exogenous Se on NO_3^- accumulation in hydroponic vegetables is still not clear. In the present study, hydroponic lettuce plants were subjected to six different concentrations(0, 0.1, 0.5, 5, 10 and 50 μmol L–1) of Se as Na2 Se O3. The effects of Se on NO_3^- content, plant growth, and photosynthetic capacity of lettuce(Lactuca sativa L.) were investigated. The results showed that exogenous Se positively decreased NO_3^- content and this effect was concentration-dependent. The lowest NO_3^- content was obtained under 0.5 μmol L–1 Se treatment. The application of Se enhanced photosynthetic capacity by increasing the photosynthesis rate(Pn), stomatal conductance(Cs) and the transpiration efficiency(Tr) of lettuce. The transportation and assimilation of NO_3^- and activities of nitrogen metabolism enzymes in lettuce were also analysed. The NO_3^- efflux in the lettuce roots was markedly increased, but the efflux of NO_3^- from the root to the shoot was decreased after treated with exogenous Se. Moreover, Se application stimulated NO_3^- assimilation by enhancing nitrate reductase(NR), nitrite reductase(Ni R), glutamine synthetase(GS) and glutamate synthase enzyme(GOGAT) activities. These results provide direct evidence that exogenous Se shows positive function on decreasing NO_3^- accumulation via regulating the transport and enhancing activities of nitrogen metabolism enzyme in lettuce. We suggested that 0.5 μmol L–1 Se can be used to reduce NO_3^- content and increase hydroponic lettuce yield. | LEI Bo BIAN Zhong-hua YANG Qi-chang WANG Jun CHENG Rui-feng LI Kun LIU Wen-ke ZHANG Yi FANG Hui TONG Yun-xin | 2018 | Journal of Integrative Agriculture2018，17，4： | 9 |
| 19 | Comparative Transcriptome Analysis of Actinidia arguta Fruits Reveals the Involvement of Various Transcription Factors in Ripening显示文摘The fruit of Actinidia arguta is typically climacteric.During ripening,the fruits produce a large amount of ethylene.Although the molecular basis of climacteric fruit ripening has been extensively studied,some aspects such as its transcriptional regulation remain unclear.Here,we compared the transcriptomes of A.arguta fruits collected at commercial harvest(sample d0)and at 6 days after harvest(sample d6)using RNA-seq.A total of 3 659 differentially expressed genes(DEGs)between samples d0 and d6 were detected,of which 2 983 and 1 104 could be functionally annotated with Gene Ontology(GO)and Clusters of Orthologous Groups(COG)pathways.DEGs involved in ethylene biosynthesis and signal transduction were identified,including ACO(c79627),ERF061(c105131),and ERF6(c99193).Transcription factors such as ERF,b HLH,NAC,MADS,and MYB were also differentially expressed between samples d0 and d6.Selected DEGs were subjected to further analysis using quantitative reverse transcription-polymerase chain reaction(q RT-PCR),and the results coincided with those of RNA-seq.Our data revealed additional transcription factors that are involved in the regulation of fruit ripening.These results provide useful information for future research on the transcriptional regulation of fruit ripening. | HUANG Guohui QU Yi LI Tong YUAN Hui WANG Aide TAN Dongmei | 2018 | Horticultural Plant Journal2018，4，1： | 9 |
| 20 | Correlation of Seven Biological Factors(Hsp90α,p53,MDM2,Bcl-2,Bax,Cytochrome C,and Cleaved caspase3)with Clinical Outcomes of ALK+ Anaplastic Large-cell Lymphoma显示文摘Objective To explore correlation of seven apoptosis‐related proteins (Hsp90α,p53,MDM2,Bcl‐2,Bax,Cytochrome C,and Cleaved caspase3) with clinical outcomes of ALK+ anaplastic large‐cell lymphoma (ALCL).Methods Using immunohistochemistry and immunofluorescence double staining methods,the expressions of these seven apoptosis‐associated proteins were studied to clarify their relationship with clinical outcomes of 36 ALK+ and 25 ALK‐ systemic ALCL patients enrolled between 1996 and 2006.The relationship of these apoptosis‐regulating proteins with NPM‐ALK status was also evaluated with the tyrosine inhibitor herbimycin A (HA) in vitro by immunocytochemistry,Western blotting and flow cytometric assays.Results The presence of Hsp90α‐,MDM2‐,Bax‐,Cytochrome C,and Cleaved caspase3‐positive tumor cells was found significantly different in ALK+ and ALK‐ ALCLs ,which was correlated with highly favorable clinical outcome.The Bcl‐2‐ and p53‐positive tumor cells were found in groups of patients with unfavorable prognosis.Inhibition of NPM‐ALK by HA could reactivate the p53 protein and subsequent apoptosis‐related proteins and therefore induced apoptosis in ALK+ ALCL cells.Conclusion Our results suggest that these seven proteins might be involved in apoptosis regulation and associated with clinical outcome of ALK+ systemic ALCLs.We also reveal a dynamic chain relation that NPM‐ALK regulates p53 expression and subsequent apoptosis cascade in ALK+ ALCLs. | LI Hui Ling HUANG Xue Ping ZHOU Xin Hua JI Tian Hai WU Zi Qing WANG Zhi Qiang JIANG Hui Yong LIU Fan Rong ZHAO Tong | 2011 | Biomedical and Environmental Sciences2011，24，6： | 9 |
