| 2 | Sodium oligomannate therapeutically remodels gut microbiota and suppresses gut bacterial amino acids-shaped neuroinflammation to inhibit Alzheimer's disease progression显示文摘Recently,increasing evidence has suggested the association between gut dysbiosis and Alzheimer's disease(AD)progression,yet the role of gut microbiota in AD pathogenesis remains obscure.Herein,we provide a potential mechanistic link between gut microbiota dysbiosis and neuroinflammation in AD progression.Using AD mouse models,we discovered that,during AD progression,the alteration of gut microbiota composition leads to the peripheral accumulation of phenylalanine and isoleucine,which stimulates the differentiation and proliferation of pro-inflammatory T helper 1(Thl)cells.The brain-infiltrated peripheral Th1 immune cells are associated with the Ml microglia aaivation,contributing to AD-associated neuroinflammation.Importantly,the elevation of phenylalanine and isoleucine concentrations and the increase of Th1 cell frequency in the blood were also observed in two small independent cohorts of patients with mild cognitive impairment(MCI)due to AD.Furthermore,GV-971,a sodium oligomannate that has demonstrated solid and consistent cognition improvement in a phase 3 clinical trial in China,suppresses gut dysbiosis and the associated phenylalanine/isoleucine accumulation,harnesses neuroinflammation and reverses the cognition impairment.Together,our findings highlight the role of gut dysbiosis-promoted neuroinflammation in AD progression and suggest a novel strategy for AD therapy by remodelling the gut microbiota. | Xinyi Wang Guangqiang Sun Teng Feng Jing Zhang Xun Huang Tao Wang Zuoquan Xie Xingkun Chu Jun Yang Huan Wang Shuaishuai Chang Yanxue Gong Lingfei Ruan Guanqun Zhang Siyuan Yan Wen Lian Chen Du Dabing Yang Qingli Zhang Feifei Lin Jia Liu Haiyan Zhang Changrong Ge Shifu Xiao Jian Ding Meiyu Geng | 2019 | Cell Research2019，29，10： | 192 |
| 3 | Energy-Efficient Multi-UAV Coverage Deployment in UAV Networks:A Game-Theoretic Framework显示文摘UAV cooperative control has been applied in many complex UAV communication networks. It remains challenging to develop UAV cooperative coverage and UAV energy-efficient communication technology. In this paper, we investigate current works about UAV coverage problem and propose a multi-UAV coverage model based on energy-efficient communication. The proposed model is decomposed into two steps: coverage maximization and power control, both are proved to be exact potential games(EPG) and have Nash equilibrium(NE) points. Then the multi-UAV energy-efficient coverage deployment algorithm based on spatial adaptive play(MUECD-SAP) is adopted to perform coverage maximization and power control, which guarantees optimal energy-efficient coverage deployment. Finally, simulation results show the effectiveness of our proposed approach, and confirm the reliability of proposed model. | Lang Ruan Jinlong Wang Jin Chen Yitao Xu Yang Yang Han Jiang Yuli Zhang Yuhua Xu | 2018 | China Communications2018，15，10： | 24 |
| 4 | Epidemiology of Diabetes in Adults Aged 35 and Older from Shanghai,China显示文摘Objective This study aimed to investigate the epidemiology of diabetes in adults from Shanghai, aged 35 and older, in 2013. Methods We estimated the diabetes prevalence in a representative sample of 18,736 adults who were selected through a multistage stratified cluster sampling process. A standard questionnaire containing questions about demographic characteristics and lifestyle factors was distributed. After an overnight fast of at least 10 hours, a venous blood sample was collected from each participant. For each patient without a history of diabetes, another blood sample was drawn 120 min after an oral glucose tolerance test to identify undiagnosed diabetes and prediabetic condition. Results Among Shanghai residents aged 35 and above, the overall weighted prevalence of diabetes was 17.6% [95% confidence interval(CI): 16.4%-18.8%]. The prevalences were 19.3% in men and 15.8% in women as well as 19.1%, 15.4%, and 16.1% in urban, suburban, and rural residents, respectively. In addition, the weighted prevalence of prediabetes was 16.5%(95% CI: 15.3%-17.8%), with the prevalences of 16.5% in men, 16.6% in women, 15.2% in urban residents, 18.0% in suburban residents, and 18.5% in rural residents. Among all patients with diabetes, 68.1%(95% CI: 64.3%-71.6%) were aware of their status, 63.5%(95% CI: 60.0%-66.9%) received diabetes treatment, but only 35.1%(95% CI: 32.4%-37.8%) had adequate glycemic control. Conclusion In Shanghai, diabetes and prediabetes are highly prevalent. However, 1/3rd of diabetes cases are undiagnosed, and the rate of glycemic control is low. | RUAN Ye YAN Qing Hua XU Ji Ying YANG Qun Di YAO Hai Hong LI Rui SHI Yan | 2016 | Biomedical and Environmental Sciences2016，29，6： | 22 |

| 7 | Genome analysis of Taraxacum kok-saghyz Rodin provides new insights into rubber biosynthesis显示文摘The Russian dandelion Taraxacum kok-saghyz Rodin(TKS), a member of the Composite family and a potential alternative source of natural rubber(NR) and inulin, is an ideal model system for studying rubber biosynthesis. Here we present the draft genome of TKS, the first assembled NR-producing weed plant. The draft TKS genome assembly has a length of 1.29 Gb, containing 46 731 predicted protein-coding genes and68.56% repeats, in which the LTR-RT elements predominantly contribute to the genome enlargement. We analyzed the heterozygous regions/genes, suggesting its possible involvement in inbreeding depression.Through comparative studies between rubber-producing and non-rubber-producing plants, we found that enzymes of the mevalonate(MVA) pathway and rubber elongation might be critical for rubber biosynthesis, and several key isoforms have been isolated and shown to be predominantly expressed in the latex, indicating their crucial functions in rubber biosynthesis. Moreover, for two important families in rubber elongation, the CPT/CPTL and REF/SRPP families, diverse evolutionary tracks have been revealed. These results provide valuable resources and new insights into the mechanism of NR biosynthesis,and facilitate the development of alternative NR-producing crops. | Tao Lin Xia Xu Jue Ruan Shizhong Liu Shigang Wu Xiujuan Shao Xiaobo Wang Lin Gan Bi Qin Yushuang Yang Zhukuan Cheng Suhua Yang Zhonghua Zhang Guosheng Xiong Sanwen Huang Hong Yu Jiayang Li | 2018 | National Science Review2018，5，1： | 22 |

| 9 | Clinical trial with traditional Chinese medicine intervention ''tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'' for chronic hepatitis B-associated liver failure显示文摘AIM:To study the clinical efficacy of traditional Chinese medicine(TCM)intervention'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')for treating liver failure due to chronic hepatitis B.METHODS:We designed the study as a randomized controlled clinical trial.Registration number of Chinese Clinical Trial Registry is Chi CTR-TRC-12002961.A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study.Participants were randomly assigned to the following three groups:(1)a modern medicine control group(MMC group,36patients);(2)a'tonifying qi and detoxification'('TQD')group(72 patients);and(3)a'tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment'('TTK')group(36patients).Patients in the MMC group received general internal medicine treatment;patients in the'TQD'group were given a TCM formula'tonifying qi and detoxification'and general internal medicine treatment;patients in the'TTK'group were given a TCM formula of'TTK'and general internal medicine treatment.All participants were treated for 8 wk and then followed at 48 wk following their final treatment.The primaryefficacy end point was the patient fatality rate in each group.Measurements of various virological and biochemical indicators served as secondary endpoints.The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups.RESULTS:At the 48-wk post-treatment time point,the patient fatality rates in the MMC,'TQD',and'TTK'groups were 51.61%,35.38%,and 16.67%,respectively,and the differences between groups were statistically significant(P<0.05).However,there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups(P>0.05).Patients in the'TTK'group had significantly higher levels of serum total bilirubin compared to MMC subjects(339.40μmol/L±270.09μmol/L vs 176.13μmol/L±185.70μmol/L,P=0.014).Serum albumin levels were significantly increased in both the'TQD'group and'TTK'group as compared with the MMC group(31.30 g/L±4.77g/L,30.72 g/L±2.89 g/L vs 28.57 g/L±4.56 g/L,P<0.05).There were no significant differences in levels of alanine transaminase among the three groups(P>0.05).Safety data showed that there was one case of stomachache in the'TQD'group and one case of gastrointestinal side effect in the'TTK'group.CONCLUSION:Treatment with'TTK'improved the survival rates of patients with liver failure due to chronic hepatitis B.Additionally,liver tissue was regenerated and liver function was restored. | Han-Min Li Zhi-Hua Ye Jun Zhang Xiang Gao Yan-Ming Chen Xin Yao Jian-Xun Gu Lei Zhan Yang Ji Jian-Liang Xu Ying-He Zeng Fan Yang Lin Xiao Guo-Guang Sheng Wei Xin Qi Long Qing-Jing Zhu Zhao-Hong Shi Lian-Guo Ruan Jia-Yao Yang Chang-Chun Li Hong-Bin Wu Sheng-Duo Chen Xin-La Luo | 2014 | World Journal of Gastroenterology2014，20，48： | 20 |
| 10 | Impact of Taurine on the proliferation and apoptosis of human cervical carcinoma cells and its mechanism显示文摘Background:Cervical cancer has the fourth highest incidence and mortality rate of all cancers in women worldwide;让seriously harms their physical and mental health.The aim of this study was to observe the roles and preliminary mechanism of Taurine(Tau)-induced apoptosis in cervical cancer cells.Methods:Cells from the human cervical cancer cell line SiHa were transfected with the recombinant plasmid pEGFP-N1-MST1(mammalian sterile 20-like kinase 1);then,the cell proliferation activity was analyzed by the MTT assay,cell apoptosis by flow cytometry,and the related protein levels by Western blotting.Results:Tau inhibited the proliferation of SiHa cells and induced apoptosis in these cells(the apoptotic rate was 21.95%in the Tau 160 mmol/L group and 30%in the Tau 320 mmol/L group),upregulated the expression of the MST1(control,0.53;Tau 40-320 mmol/L groups,0.84-1.45)and Bax(control,0.45;Tau 40-320 mmol/L groups,0.64-1.51)proteins(P<0.01),and downregulated the expression of Bcl-2(control,1.28,Tau 40-320 mmol/L groups,0.93-0.47)(P<0.01).The overexpression of MST1 promoted the apoptosis of SiHa cells,enhanced the apoptosis-inductive effects of Tau(P<0.01),upregulated the expression of the proapoptotic proteins p73,p53,PUMA(p53 upregulated modulator of apoptosis),and caspase-3,and promoted the phosphorylation of YAP(Yes-associated protein).Conclusions:Tau inhibited the proliferation and induced the apoptosis of cervical cancer SiHa cells.The MST1 protein plays an important role in the Tau-induced apoptosis of cervical cancer cells. | Hua Li Wen-Jing Ruan Li-Qiao Liu Hui-Fang Wan Xiao-Hong Yang Wei-Feng Zhu Le-Han Yu Xia-Li Zhang Fu-Sheng Wan | 2019 | Chinese Medical Journal2019，，8： | 18 |
| 11 | Effect of Ce doping into V_(2)O_(5)-WO_(3)/TiO_(2) catalysts on the selective catalytic reduction of NO_(x) by NH_(3)显示文摘In this work, the effectiveness of V_2O_5-WO_3/TiO_2 catalysts modified with different CeO_2 contents by impregnation and co-precipitation methods on the selective catalytic reduction of NOxby NH3 have been studied comparatively by various experimental techniques. The results showed that the NO conversion of V_2O_5-WO_3/CeO_2-TiO_2 catalysts modified by co-precipitation method obviously increased with the Ce doping contents in the studied range below 20%(All Ce contents are in mass fractions), but the NO conversion of V_2O_5-WO_3/CeO_2/TiO_2 catalysts modified by impregnation methods was lower than V_2O_5-WO_3/CeO_2-TiO_2 catalysts especially beyond 2.5% Ce doping contents. The V_2O_5-WO_3/CeO_2-TiO_2 catalysts showed better SCR activity, wider reaction window, and higher sulfur and water resistance. The characterization results elucidated that the modified catalysts by co-precipitation method exhibited higher specific surface area, much better dispersity of Ce component, more Ce^(3+)species and more Br?nsted acid sites than that by impregnation. The vacancies caused by more Ce^(3+)species were favorable for more NO oxidation to NO_2, and the interaction between Ce species and WOxspecies generated more Br?nsted acid sites. It could be supposed that dispersed Ce Oxspecies and WOxspecies offered more second active centers respectively to adsorb oxygen and activate ammonia as co-catalysis to the primary active center of V ions, thus facilitated the better SCR activity of modified V_2O_5-WO_3/CeO_2-TiO_2 catalysts by coprecipitation methods. The co-precipitation methods with Ce component were more suitable for production of modified commercial V_2O_5-WO_3/TiO_2 catalysts. | Mengyin Chen Mengmeng Zhao Fushun Tang Le Ruan Hongbin Yang Ning Li | 2017 | Journal of Rare Earths2017，35，12： | 18 |
| 12 | Suppression of Fusarium Wilt of Banana with Application of Bio-Organic Fertilizers显示文摘Fusarium wilt is one of the most serious diseases of banana plants caused by soil-borne pathogen Fusarium oxysporum f.sp. cubense(FOC). In this study a pot experiment was conducted to evaluate the effects of different bio-organic fertilizers(BIOs) on Fusarium wilt of banana, including the investigations of disease incidence, chitinase and β-1,3-glucanase activities of banana plants, and FOC populations as well as soil rhizosphere microbial community. Five fertilization treatments were considered, including chemical fertilizer containing the same N, P and K concentrations as the BIO(control), and matured compost mixed with antagonists Paenibacillus polymyxa SQR-21 and Trichoderma harzianum T37(BIO1), Bacillus amyloliquefaciens N6(BIO2), Bacillus subtilis N11(BIO3), and the combination of N6 and N11(BIO4). The results indicated that the application of BIOs significantly decreased the incidence rate of Fusarium wilt by up to 80% compared with the control. BIOs also significantly promoted plant growth, and increased chitinase andβ-1,3-glucanase activities by 55%–65% and 17.3%–120.1%, respectively, in the banana roots. The population of FOC in the rhizosphere soil was decreased significantly to about 104 colony forming units g-1with treatment of BIOs. Serial dilution plating and denaturing gradient gel electrophoresis analysis revealed that the application of BIOs increased the densities of bacteria and actinomycetes but decreased the number of fungi in the rhizosphere soil. In general, the application of BIOs revealed a great potential for the control of Fusarium wilt disease of banana plants. | ZHANG Nan HE Xin ZHANG Juan W.RAZA YANG Xing-Ming RUAN Yun-Ze SHEN Qi-Rong HUANG Qi-Wei | 2014 | Pedosphere2014，24，5： | 15 |
| 13 | Lymphocyte-to-monocyte ratio predicts survival of patients with hepatocellular carcinoma after curative resection显示文摘AIM: To investigate the prognostic value of preoperative lymphocyte-to-monocyte ratio(LMR) in patients with hepatocellular carcinoma(HCC) undergoing curative hepatectomy.METHODS: Clinicopathological data of 210 hepatitis B virus(HBV)-associated HCC patients who were treated by radical hepatic resection between 2003 and 2010 were retrospectively analyzed. None of the patients received any preoperative anticancer therapyor intraoperative radiofrequency ablation. The diagnosis was confirmed by pathological examination after surgery. Absolute peripheral blood lymphocyte and monocyte counts were derived from serum complete blood cell count before surgery,and LMR was calculated by dividing lymphocyte count by monocyte count. The best cutoff was determined by receiver operating characteristics(ROC) curve analysis. Correlations between LMR levels and clinicopathological features were assessed using the χ2 test. Survival outcomes were estimated using the Kaplan-Meier method and compared by the log-rank test. Univariate and multivariate analyses were performed to evaluate the prognostic impact of LMR and other clinicopathological factors on overall survival(OS) and recurrence-free survival(RFS),using the Cox proportional hazards model.RESULTS: The optimal cutoff value of LMR for survival analysis was 3.23,which resulted in the most appropriate sensitivity of 55.3% and specificity of 74.7%,with the area under the curve(AUC) of 0.66(95%CI: 0.593-0.725). All patients were dichotomized into either a low(≤ 3.23) LMR group(n = 66) or a high(> 3.23) LMR group(n = 144). A low preoperative LMR level was significantly correlated with the presence of cirrhosis,elevated levels of total bilirubin and larger tumor size. Patients with a low LMR level had significantly reduced 5-year OS(61.9% vs 83.2%,P < 0.001) and RFS(27.8% vs 47.6%,P = 0.009) compared to those with a high LMR level. Multivariate analyses indicated that a lower LMR level was a significantly independent predictor of inferior OS(P = 0.003) and RFS(P = 0.006). Subgroup analysis indicated that survival outcome was significantly more favorable in cirrhotic patients with LMR > 3.23. However,there were no differences between low and high LMR groups for OS and RFS in non-cirrhotic patients.CONCLUSION: Preoperative LMR was demonstrated for the first time to serve as an independent prognostic factor in HBV-associated HCC patients after curative resection. Prospective studies with larger cohorts for validation are warranted. | Ze-Xiao Lin Dan-Yun Ruan Yang Li Dong-Hao Wu Xiao-Kun Ma Jie Chen Zhan-Hong Chen Xing Li Tian-Tian Wang Qu Lin Jing-Yun Wen Xiang-Yuan Wu | 2015 | World Journal of Gastroenterology2015，21，38： | 15 |
| 14 | A mussel-inspired supramolecular hydrogel with robust tissue anchor for rapid hemostasis of arterial and visceral bleedings显示文摘In recent years,the developed hemostatic technologies are still difficult to be applied to the hemostasis of massive arterial and visceral hemorrhage,owing to their weak hemostatic function,inferior wet tissue adhesion,and low mechanical properties.Herein,a mussel-inspired supramolecular interaction-cross-linked hydrogel with robust mechanical property(308.47±29.20 kPa)and excellent hemostatic efficiency(96.5%±2.1%)was constructed as a hemostatic sealant.Typically,we combined chitosan(CS)with silk fibroin(SF)by cross-linking them through tannic acid(TA)to maintain the structural stability of the hydrogel,especially for wet tissue adhesion ability(shear adhesive strength=29.66±0.36 kPa).Compared with other materials reported previously,the obtained CS/TA/SF hydrogel yielded a lower amount of blood loss and shorter time to hemostasis in various arterial and visceral bleeding models,which could be ascribed to the synergistic effect of wound closure under wet state as well as intrinsic hemostatic activity of CS.As a superior hemostatic sealant,the unique hydrogel proposed in this work can be exploited to offer significant advantages in the acute wound and massive hemorrhage with the restrictive access of therapeutic moieties. | Ziwen Qiao Xueli Lv Shaohua He Shumeng Bai Xiaochen Liu Linxi Hou Jingjing He Dongmei Tong Renjie Ruan Jin Zhang Jianxun Ding Huanghao Yang | 2021 | Bioactive Materials2021，6，9： | 14 |
| 15 | Differentiation of intrahepatic cholangiocarcinoma from hepatocellular carcinoma in high-risk patients: a predictive model using contrast-enhanced ultrasound显示文摘AIM To develop a contrast-enhanced ultrasound(CEUS)predictive model for distinguishing intrahepatic cholangiocarcinoma(ICC) from hepatocellular carcinoma(HCC) in high-risk patients.METHODS This retrospective study consisted of 88 consecutive high-risk patients with ICC and 88 high-risk patients with HCC selected by propensity score matching between May 2004 and July 2016. Patients were assigned to two groups, namely, a training set and validation set, at a 1:1 ratio. A CEUS score for diagnosing ICC was generated based on significant CEUS features. Then, a nomogram based on the CEUS score was developed, integrating the clinical data. The performance of the nomogram was then validated and compared with that of the LR-M of the CEUS Liver Imaging Reporting and Data System(LI-RADS).RESULTS The most useful CEUS features for ICC were as follows: rim enhancement(64.5%), early washout(91.9%), intratumoral vein(58.1%), obscure boundary of intratumoral non-enhanced area(64.5%), and marked washout(61.3%, all P < 0.05). In the validation set, the area under the curve(AUC) of the CEUS score(AUC = 0.953) for differentiation between ICC and HCC was improved compared to the LI-RADS(AUC = 0.742)(P < 0.001). When clinical data were added, the CEUS score nomogram was superior to the LI-RADS nomogram(AUC: 0.973 vs 0.916, P = 0.036, Net Reclassification Improvement: 0.077, Integrated Discrimination Index: 0.152). Subgroup analysis demonstrated that the CEUS score model was notably improved compared to the LIRADS in tumors smaller than 5.0 cm(P < 0.05) but not improved in tumors smaller than 3.0 cm(P > 0.05).CONCLUSION The CEUS predictive model for differentiation between ICC and HCC in high-risk patients had improved discrimination and clinical usefulness compared to the CEUS LIRADS. | Li-Da Chen Si-Min Ruan Jin-Yu Liang Zheng Yang Shun-Li Shen Yang Huang Wei Li Zhu Wang Xiao-Yan Xie Ming-De Lu Ming Kuang Wei Wang | 2018 | World Journal of Gastroenterology2018，24，33： | 14 |
| 16 | Natural variation in the promoter of OsHMA3 contributes to differential grain cadmium accumulation between Indica and Japonica rice显示文摘Rice is a major source of cadmium(Cd) intake for Asian people. Indica rice usually accumulates more Cd in shoots and grains than Japonica rice. However, underlying genetic bases for differential Cd accumulation between Indica and Japonica rice are still unknown. In this study, we cloned a quantitative trait locus(QTL) grain Cd concentration on chromosome 7(GCC7) responsible for differential grain Cd accumulation between two rice varieties by performing QTL analysis and map-based cloning. We found that the two GCC7 alleles, GCC7PA64s and GCC793-11, had different promoter activity of OsHMA3,leading to different OsHMA3 expression and different shoot and grain Cd concentrations. By analyzing the distribution of different haplotypes of GCC7 among diverse rice accessions, we discovered that the high and low Cd accumulation alleles, namely GCC793-11 and GCC7PA64s, were preferentially distributed in Indica and Japonica rice,respectively. We further showed that the GCC7PA64sallele can be used to replace the GCC793-11 allele in the super cultivar 93-11 to reduce grain Cd concentration without adverse effect on agronomic traits. Our results thus reveal that the QTL GCC7 with sequence variation in the OsHMA3 promoter is an important determinant controlling differential grain Cd accumulation between Indica and Japonica rice. | Chao-Lei Liu Zhen-Yu Gao Lian-Guang Shang Chang-Hong Yang Ban-Pu Ruan Da-Li Zeng Long-Biao Guo Fang-Jie Zhao Chao-Feng Huang Qian Qian | 2020 | Journal of Integrative Plant Biology2020，62，3： | 12 |

| 18 | 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 |
| 19 | Gossypol: phytoalexin of cotton显示文摘Sesquiterpenoids are a class of 15-carbon secondary metabolites that play diverse roles in plant adaptation to environment.Cotton plants accumulate a large amount of sesquiterpene aldehydes(including gossypol)as phytoalexins against pathogens and herbivores.They are stored in pigment glands of aerial organs and in epidermal layers of roots.Several enzymes of gossypol biosynthesis pathway have been characterized,including 3-hydroxy-3-methylglutaryl coenzyme A reductase(HMGR)and farnesyl diphosphate synthase(FPS)that catalyze the formation of the precursor farnesyl diphosphate(FPP),(+)-δ-cadinene synthase(CDN)which is the first enzyme committed to gossypol biosynthesis,and the downstream enzymes of CYP706B1 and methyltransferase.Expressions of these genes are tightly regulated during cotton plants development and induced by jasmonate and fungi elicitors.The transcription factor Ga WRKY1 has been shown to be involved in gossypol pathway regulation.Recent development of new genomic platforms and methods and releases of diploid and tetraploid cotton genome sequences will greatly facilitate the elucidation of gossypol biosynthetic pathway and its regulation. | Xiu Tian Juxin Ruan Jinquan Huang Xin Fang Yingbo Mao Lingjian Wang Xiaoya Chen Changqing Yang | 2016 | Science China(Life Sciences)2016，59，2： | 10 |
