Guihaia's launch, we retrospected the journal development, which could be divided into four stages: initially developed from an in-house journal; published at home and abroad, and journal influence surged; seized the opportunity to realize journal leapfrog development; created journal brand characteristics and promoted the overall development of the journal with featured columns. And we analyzed the academic influence of the journal from the aspects of published information, objects of reports(authors), sources and characteristics of authors, funding projects, citations by domestic journals, downloads of published articles and so on, based on the data of CNKI, CNKI CItation Database and related evaluation institutions through citation analysis method. We also summarized the achievements, such as finding and nurturing talents and providing good growth platfrom for them; improving the evaluation indexes and expanding the influence of the journal; focusing on the national strategy and major social needs to create disciplinary characteristics of the column; the author group and the reader group enlargement and the editorial board construction and so on. Looking ahead, we need to face great challenges. In this regard, we put forward the following ideas: First, center on the task of building an innovative country and a scientific and technological power, enhance academic leading ability and brand influence; Second, focus on the major strategic needs of the country, create special columns on major themes, and serve the main battlefield of economic and social development; Third, follow the trend of media convergence, ad apt to the direction of mobile and intelligent development, explore new publishing models such as all-media publishing, and speed up the development of journal convergence; Fourth, appropriately increase the proportion of international editors, provide long English abstracts of papers, strengthen the construction of bilingual academic websites, and improve the level of open running journal and international communication ability, and strive to build a first-class domestic academic journal with international influence.]]> 2021/11/15 17:12:49 *]]> JIANG Qiaoyuan, LI Li, LI Xiankun^* 18true 2021/11/15 17:12:49 1, LI Yanpeng¹, LI Yide^1*, HONG Xiaojiang², ZHOU Zhang¹, LUO Tushou¹, CHEN Jie¹, LIN Mingxian³, ZHANG Bin⁴]]> XU Han¹, LI Yanpeng¹, LI Yide^1*, HONG Xiaojiang², ZHOU Zhang¹, LUO Tushou¹, CHEN Jie¹, LIN Mingxian³, ZHANG Bin⁴ 17true th Five-Year Plan for National Economic and Social Development and the Long-term Targets for 2035 of the People's Republic of China, the rescue of PSESP is explicitly incorporated into the special aims at the conservation of important ecosystem and ecological restoration. The PSESP rescue and protection is a long-term systematic work with strong science, high technical and professional requirements. For scientifically conserving PSESP, rescue protection and system study should be given an equal weight. Undoubtedly, systematic research on the PSESP conservation is an important task to support their effective conservations. This paper is trying to systematically review the recent research works on the PSESP conservation, focusing on the surveys and assessment of the current populations or individual status(including confirmation of species taxonomic status), eco-biological characteristics, propagation techniques and genetic diversity, with the aim to find new theories and to form new ideas for the PSESP conservation. Finally, three insights into priorities for future conservation research of PSESP in China are proposed, which could be a reference for further PSESP conservation research.]]> 2021/11/15 17:12:49 *, LIU Detuan, ZHANG Pin]]> SUN Weibang^*, LIU Detuan, ZHANG Pin 16true Vegegraph of China, based on previous publications and vegetation plot data.

The results were as follows:(1)The 103 species of rare and endangered spermatophytes investigated in Guizhou were subjected to in-situ conservation measures, but so far, the effect on the reduction of endangered threat was not obvious, and rescue ex-situ protection was still necessary. The 103 species comprised 23 critically endangered(CR), 30 endangered(EN), 40 vulnerable(VU), 7 near threatened(NT), and 3 least concern(LC)species.

Many species of Dendrobium are traditional valuable medicinal plants and have pharmacological activities in antitumor. In recent years, remarkable progress has been made in the antitumor researches of Dendrobium species. The main antitumor ingredients, extraction methods and antitumor mechanisms of Dendrobium species were summarized in this paper. The main antitumor active ingredients of Dendrobium are polysaccharides, alkaloids, phenanthrenes, benzyls and fluorenones. The antitumor mechanisms of Dendrobium species mainly include enhancing body immunity, inhibiting proliferation of cancer cells, promoting apoptosis of cancer cells, regulating or blocking cancer cell cycle, antioxidation and scavenging free radicals, and changing signal pathway conduction. Based on previous researches, we further proposed that much more effort are needed on the antitumor researches of Dendrobium species. For example, exploring more antitumor Dendrobium resources and their characteristic ingredients, analyzing their antitumor mechanism, and establishing comprehensive evaluation system. This article could provide experimental and theoretical foundations for developing new antitumor medicine from Dendrobium species, and provide scientific basis for the rational and effective utilizatin of Dendrobium resources.]]> 2021/11/15 17:12:50 *, ZHAO Meili, LI Hejuan, HU Yue, CHEN Jianbing]]> LI Jian, WANG Meina^*, ZHAO Meili, LI Hejuan, HU Yue, CHEN Jianbing 3true Andrographis paniculata, known as ‘Chuanxinlian' in China, is an important southern medicine in China. Its main active ingredients, andrographolide components, has good pesticide effects on heat-clearing and anti-bacterial and anti-inflammatory, etc. Modern medical research has demonstrated that they also have profound effects in anti-HIV, anti-thrombus, liver protection and so on. Because they are difficult to be synthesized artificially, to increase the biosynthesis of andrographolide components in A. paniculata by cultivation regulation and breeding methods is of great significance to improve the quality of this medicinal material. To provide reference for related research in these fields, this paper reviewed the relationship between accumulation of andrographolide components and plant development, the effects of cultivation measures and environmental factors on the accumulation of andrographolide components, and the research advances in biosynthesis of andrographolide components and its molecular regulatory mechanism in the last decade worldwide. We also put forward three aspects which should be focused on in future studies aiming at enhancing the biosynthesis and accumulation of andrographolides components in A. paniculata:(1)To further identify the biosynthetic pathway of andrographolide components and the functions of key genes, and to elucidate the mechanism of andrographolides accumulation at molecular level;(2)To deeply study the laws of growth and development, yield and quality formation, and their interrelations in A. paniculata with the combination of molecular biological approaches and crop cultivation theories;(3)To reveal the signal regulation network in the biosynthesis of andrographolide components.]]> 2021/11/15 17:12:50 1,2, JIAN Shaofen^1,2, CHEN Dongliang^1,2, MIAO Jianhua^1,2]]> ZHONG Chu^1,2, JIAN Shaofen^1,2, CHEN Dongliang^1,2, MIAO Jianhua^1,2 2true Polyspora Sweet are evergreen tree of Theaceae with 50 species, mainly distributed in South Asia and Southeast Asia.
