An Overview of Research on Przewalskia tangutica Maxim., an Endangered Tibetan Medicinal Plant

Przewalskia tangutica Maxim. （Solanaceae： Przewalskia） is a perennial herbaceous plant, which is endemic to Tibet and is a rare and endangered Tibetan medicinal plant. In this paper, the morphological characteristics, seed germination, tissue culture, flower development characteristics, chemical composition, element content and resource characteristics of P. tangutica are summarized and analyzed. Combined with the survival status of P. tangutica, it is suggested that the research on ecological adaptation, survival mechanism, endangerment mechanism and eco- logical functions of P. tangutica should be strengthened.

A Review of Research on Sponge Cities

Rapid urbanization has led to an increase o f urban artificial landscapes and the transformation of die earths surface, which has caused the dty to lose its functions of flood control and water purificatioiL There are frequent urban flooding and waterlogging, deterioration of water quality in rivets and lakes, and increasing water and environmental problems. In response to these situations, the state proposed the construction of a sponge dty. In this paper, the background and rcsearch significance of the sponge city were expounded, the domestic and foreign related reseatch was summarized, and further thinking about the sponge dty in Chim was put forward, in order to clarify the research context of the sponge dty and provide the basis for tiie later research.

Study on TCM intervention of NF-κB signal pathway in the treatment of bronchial asthma

Bronchial asthma(asthma for short)is a common chronic respiratory disease inchildren,which has adverse effects on children's physical and mental health.Nuclear factorκB(NF-κB)signaling pathway is an important transcription factor in airway inflammation,and plays an important role in airway inflammation and airway remodeling in asthma.Clinical studies have found that traditional Chinese medicine has positive effects in the treatment of asthma.Hence,this paper aims to review the literatures on the treatment of asthma through traditional Chinese medicine compound and single herbs and extracts by regulating the NF-κB signaling pathway for nearly a decade.It is found that traditional Chinese medicine can inhibit airway inflammation,relieve airway smooth muscle spasm and reduce airway resistance through the regulation of NF-κB signaling pathway,so as to play a key role in the treatment of asthma,and provide a scientific basis for the treatment of asthma with traditional Chinese medicine.

Policies for Traditional Medicine of China in Modern Times

Traditional medicine has not only made important contributions to the reproduction and prosperity of the Chinese nation for a long time,and it has also had a positive impact on human health and world civilization.Pharmaceutical policies have a significant impact on the development of the pharmaceutical industry.In this article,the research on the development of pharmaceutical policies after the founding of the People's Republic of China is summarized.This is of great significance to formulate scientific and efficient policy measures to promote the development of the pharmaceutical industry.

Survey of dose-effect relationship in Chinese materia medica

The research on the dose-effect relationship in Chinese materia medica is delayed due to the complexity of its composition, multi-efficacy, multi-targeting and other factors. Many experts put forward relevant research ideas and methods and worked out more and more research results in literature, experimental and clinical categories because of the progress of statistical methods and scientific and technological means in recent years. In this paper, these results were preliminarily combed to show the basic situation of dose-effect relationship research in Chinese materia medica.

An overview of rice genetics research in China

Congratulations to the Genetics Society of China on their 40;anniversary! Genetics has expanded in scope in that time frame and has penetrated into many areas of biology, medicine and agriculture. Genetics is poised to continue that trajectory into the future with promises of new understanding and new technologies for the benefit to society. Here, we will highlight some of the

Review and Prospect of Research on Settlement Adaptation

Adaptation research is a key area in the research on the Sciences of Human Settlements. Based on tracing the origin of the concept of adaptation and reviewing relevant studies, this paper attempts to propose the concept of settlement adaptation and answer the three core questions of “object of adaptation,” “subject of adaptation,” and “type and process of adaptation.” Then, the paper summarizes the main contents of the settlement adaptation research, including the research on adaptive construction of traditional settlements centered on climate adaptation, water adaptation, and terrain adaptation, as well as that on the evolutionary characteristics and mechanisms in the process of settlement adaptation. In the end,the paper points out the directions of future settlement adaptation research: systematic and holistic theoretical research;cross-scale, inter-temporal,and multi-regional empirical research;methodological innovation supported by emerging technologies;planning and design innovation to address current challenges. The relevant research and practice of settlement adaptation can provide support and reference for the sustainable development of settlements.

Reviews and prospects in satellite range scheduling problem

With the increasing number of space satellites,the demand for satellite communication(including maneuvering,command uploading and data downloading)has also grown significantly.However,the actual communication resources of ground station are relatively limited,which leads to an oversubscribed problem.How to make use of limited ground station resources to complete satellite communication requests more fully and efficiently in the strict visible time is the focus of satellite range scheduling research.This paper reviews and looks forward to the research on Satellite Range Scheduling Problem(SRSP).Firstly,SRSP is defined as the scheduling problem of establishing communication between satellites and ground stations,and the classification and development of SRSP are introduced.Then,this paper analyzes three common problem description models,and establishes a mathematical model based on the analysis of optimization objectives and constraints.Thirdly,this paper classifies and summarizes the common solving methods of SRSP,and analyzes their characteristics and application scenarios.Finally,combined with the work in this paper,the future research direction of SRSP is envisioned.
