| 1 | Modulation of Sex Expression in Four Forms of Watermelon by Gibberellin, Ethephone and Silver Nitrate显示文摘There has been no systematic research on the effect of plant growth regulators and silver nitrate treatments on the control of sex expression in watermelon. In this study, we tested sex expression responses of four watermelon forms(monoecism, gynoecism, andromonoecism,and hermaphrodite) to gibberellin, ethephon and silver nitrate treatments. Results have shown that, in monoecious plants, gibberellins(GA_3)and ethephon treatments reduced the percentage of female flowers and delayed the occurrence of the first female flower, while silver nitrate induced the formation of bisexual flowers. In gynoecious plants, both ethephon and silver nitrate treatments transformed some female flowers into bisexual flowers, and treatment with ethephon resulted in a mass of abnormal flowers, while no obvious effect of treatment with GA_3 was observed. In andromonoecious plants, ethephon and GA_3 treatments delayed the occurrence of the first bisexual flower, and GA_3 reduced the percentage of bisexual flowers, while no distinct effect for silver nitrate treatment was observed. In hermaphroditic plants, ethephon treatment induced the appearance of numerous abnormal flowers, while no obvious effects for GA_3 and silver nitrate treatments were observed.We analyzed the transcription levels of all the expressed aminocyclopropane-1-carboxylic acid synthase(ACS) homologues in two gynoecious mutants and their wild types. We also tested the gene expression of CitACS4 which had been recognized as the andromonoecious gene in all treatments. All these results suggested that the best masculinizing treatment for breeding of the gynoecious line is silver nitrate, which repressed the expression of CitACS4 and induced many bisexual flowers for use in self-fertilization subsequently. | ZHANG Jie SHI Jianting JI Gaojie ZHANG Haiying GONG Guoyi GUO Shaogui REN Yi FAN Jianguang TIAN Shouwei XU Yong | 2017 | Horticultural Plant Journal2017，3，3： | 6 |
| 2 | Prevalence of Metabolic Syndrome and Risk Factors Among Chinese Adults:Results from a Population-Based Study—Beijing,China,2017–2018显示文摘Summary What is already known about this topic?Metabolic syndrome(MetS)is one of the most easily available health indicative markers for cardiovascular diseases,and it has become a major public health problem worldwide due to increasing urbanization and aging populations.The prevalence of MetS increased dramatically in China,however,there are no records of MetS defined by the 2017 Chinese Diabetes Society for Beijing by far.What is added by this report?In this study,the data of 24,412 participants aged 18–74 years from a large population-based study in Beijing was collected.The overall prevalence of MetS among Beijing residents was 24.5%.The prevalence was 35.2%in males and 15.4%in females.What are the implications for public health practice?Effective public health strategies should target males,people with older age,lower education,higher body mass index,smokers,those who drink alcohol,those who are unemployed or retired,and those who live in rural areas on MetS prevention and control. | Jufen Liu Qingping Liu Zhiwen Li Jing Du Chao Wang Yanlin Gao Zaihua Wei Jing Wang Yunping Shi Jianting Su Yang Liu Ping Wang Chunyan Xie Gang Li Bing Shao Le Zhang | 2022 | China CDC weekly2022，4，29： | 4 |

| 4 | Mutation in the gene encoding 1-aminocyclopropane-1-carboxylate synthase 4 (CitACS4) led to andromonoecy in watermelon显示文摘Although it has been reported previously that ethylene plays a critical role in sex determination in cucurbit species, how the andromonoecy that carries both the male and hermaphroditic flowers is determined in watermelon is still unknown. Here we showed that the watermelon gene 1-aminocyclopropane-1-carboxylate synthase 4(Cit ACS4), expressed specifically in carpel primordia, determines the andromonoecy in watermelon. Among four single nucleotide polymorphism(SNPs) and one InDel identified in the coding region of Cit ACS4, the C364 W mutation located in the conserved box 6 was cosegregated with andromonoecy. Enzymatic analyses showed that the C364 W mutation caused a reduced activity in Cit ACS4. We believe that the reduced Cit ACS4 activity may hamper the programmed cell death in stamen primordia, leading to the formation of hermaphroditic flowers. | Gaojie Ji Jie Zhang Haiying Zhang Honghe Sun Guoyi Gong Jianting Shi Shouwei Tian Shaogui Guo Yi Ren Huolin Shen Junping Gao Yong Xu | 2016 | Journal of Integrative Plant Biology2016，58，9： | 1 |

| 6 | Effect of Elephantopus scaber L.Extract on Acute Pleurisy in Rats显示文摘[Objectives]To study the anti-inflammatory effect of Elephantopus scaber L.extract on acute pleurisy induced by carrageenan in rats,and to explore its anti-inflammatory mechanism.[Methods]The active sites of E.scaber L.were extracted by ethanol reflux method.The extracts of different concentrations of E.scaber L.were used as the study object,and dexamethasone was used as the positive control drug.The anti-inflammatory effects of E.scaber L.extracts were studied by measuring the levels of malondialdehyde(MDA),prostaglandin E_(2)(PGE_(2)),tumor necrosis factor(TNF-α),interleukin-1β(IL-1β)in pleural fluid and serum nitric oxide(NO),MDA,PEG_(2),TNF-α,IL-1βin rats with acute pleurisy induced by carrageenan.[Results]E.scaber L.extracts in three doses could reduce the levels of inflammatory factors in pleural fluid and serum,and inhibit acute pleurisy in rats.It was speculated that the anti-inflammatory mechanism was related to the inhibition of the release of inflammatory factors and the antioxidant effect of extracts of three doses of E.scaber L.[Conclusions]This experiment provides a basis for the development and application of E.scaber L. | Yan ZHANG Jianting GAO Xinchao SHI Hailong LIU Xin HE | 2024 | Medicinal Plant2024，15，1： | 0 |
| 7 | Improved YOLOv3 Infrared Image Pedestrian Detection Algorithm显示文摘Security surveillance is widely used in daily life.For nighttime or complicated monitoring environments,this article proposes an infrared pedestrian monitoring based on YOLOv3.In the original YOLOv3 network structure,two aspects of optimization were made.One was to optimize the scale in the residual structure,and the rich features of the deconvolution layer were added to the original residual structure.The other was to use the DenseNet network to enhance the features.The optimization of fusion ability and delivery ability effectively improves the detection ability for small targets,and the pedestrian detection performance based on infrared images.After comparative testing,compared with YOLOv3,the overall mean average precision is improved by 4.39%to 78.86%. | Jianting Shi Guiqiang Zhang Jie Yuan Yingtao Zhang | 2020 | 国际计算机前沿大会会议论文集2020，，1： | 0 |
