Analysis of the Development Status and Prospect of China's Agricultural Sensor Market under Smart Agriculture.

Agricultural sensors are essential technologies for smart agriculture, which can transform non-electrical physical quantities such as environmental factors. The ecological elements inside and outside of plants and animals are converted into electrical signals for control system recognition, providing a basis for decision-making in smart agriculture. With the rapid development of smart agriculture in China, agricultural sensors have ushered in opportunities and challenges. Based on a literature review and data statistics, this paper analyzes the market prospects and market scale of agricultural sensors in China from four perspectives: field farming, facility farming, livestock and poultry farming and aquaculture. The study further predicts the demand for agricultural sensors in 2025 and 2035. The results reveal that China's sensor market has a good development prospect. However, the paper garnered the key challenges of China's agricultural sensor industry, including a weak technical foundation, poor enterprise research capacity, high importation of sensors and a lack of financial support. Given this, the agricultural sensor market should be comprehensively distributed in terms of policy, funding, expertise and innovative technology. In addition, this paper highlighted integrating the future development direction of China's agricultural sensor technology with new technologies and China's agricultural development needs.

Research progress in extracorporeal shock wave therapy for upper limb spasticity after stroke.

Spasticity is one of the most common complications after stroke. With the gradual intensification of spasticity, stroke patients will have a series of problems such as joint ankylosis and movement restriction, which affect the daily activities and increase the burden on patients' families, medical staff and society. There are many ways to treat post-stroke spasticity before, including physical therapy and exercise therapy, drug therapy, surgery and so on, but not satisfied because of a few shortcomings. In recent years, many researchers have applied extracorporeal shock wave therapy (ESWT) for the treatment of post-stroke spasm and achieved good clinical effect, because it is non-invasive, safe, easy to operate, low cost and other advantages compared with other treatment methods. This article reviews the research progress and existing problems of ESWT in the treatment of post-stroke spasticity.

[Development strategy and current situation of Chinese patent medicine for children in China].

This study took the 2020 edition of Chinese Pharmacopoeia(ChP) and the 2018 edition of National Essential Drug List(NEDL) for children as research carriers to systematically analyze the current situation of and problems in the use of Chinese patent medicine for children(CPMC) in China. In view of the problems of imprecise dosage, incomplete safety information, and lack of sui-table varieties, dosage form and specification of CPMC in China, development strategy of CPMC in the future was proposed. It is reco-mmended to carry out systematic post-marketing revaluation studies of CPMC, encourage the development of new varieties or new dosa-ge forms suitable for children, advocate the continuous promotion of real-world studies on children, and expand the information on the use of CPMC with real-world data, so as to lay the foundation for post-marketing revaluation of CPMC and guide the rational use of clini-cal medicines. This study was expected to build a positive policy ecosystem to ensure the supply of CPMC, and promote the high-quality development of CPMC.

Aims: The purposes of this study are (1) to understand the current employment situation of master's graduates in Public Health and Preventive Medicine (PHPM) and (2) to provide evidence for career guidance and training of competent PHPM personnel. Methods: The master's graduates of the School of Public Health from the years 2014-2018 who majored in PHPM were chosen as research subjects. Questionnaires were distributed, and completed questionnaires were collected. The employment situation and characteristics of these graduates were analyzed based on the questionnaire data. Results: The employment rate of these graduates was 95.45%. They were employed mainly in hospitals, followed by colleges and centers for disease control and prevention. The initial salaries were low. Graduates whose jobs barely or not at all matched their areas of specialization were 23.64 or 6.36%, respectively. Nevertheless, the percentage of students who had remained with their jobs since graduation was 82.73%. A total of 40% of the graduates were neutral about or dissatisfied with their jobs. Furthermore, 29% of them claimed that they were undervalued by their employers. Last, but not least, graduates were encouraged to gain experience in creativity, organizational or management skills, social networking experience, and interpersonal and professional skills. Conclusion: Overall, the employment status of master's graduates in PHPM is good. Problems such as low initial salaries, jobs not matching graduates' areas of specialization, and feelings of being undervalued by employers were observed. It is necessary to improve employment outcomes by revising training models, formulating employment policies, and implementing training efforts.

[Inheritance and development of traditional Mongolian medicine processing].

The processing of Mongolian medicine,which is called " mort harl" in Mongolian language,refers to a traditional processing technology to " tame" some toxic,aggressive,ineffective or inconvenient Mongolian medicines,so as to make it " compliant" to clinical needs. It is the summary of long-term experience in drug preparation by Mongolian medicine experts,one of the bridges for the dialectical unity of Mongolian medicine,the essential content in evaluation of the clinical efficacy of Mongolian medicine and the study of Mongolian medicine modernization,and also the important soft power carrier of " intangible cultural heritage" and " grassland culture" in Inner Mongolia autonomous region. In this study,the processing history,purpose,crafts,mechanism,processing standards and quality standards of Mongolian medicine were explained,and some suggestions were proposed for the problems of the Mongolian medicine processing and development: focus on the basic theory of Mongolian medicine and the clinical experience of Mongolian medicine in the development of traditional Mongolian medicine processing; strengthen the literature research on the processing method of Mongolian medicine; establish comprehensive and systematic Mongolian medicine concocts standards and quality standards; enhance the research and development of special processing equipment and process quality control instruments for Mongolian medicine; and strengthen the training of professional technicians,the protection of copyright in Mongolian medicine processing,and scientific research on Mongolian medicine processing.

[Thinking on safety of "toxic" traditional Chinese medicine for external use].

In recent years,the safety of " toxic" traditional Chinese medicine has received great attention. Similarly,the safety of " toxic" Chinese medicines for external use should not be ignored. In this paper,the adverse reactions of toxic Chinese medicine for external use were systematically studied; the causes for adverse reactions were analyzed; and the key problems on the external use of toxic Chinese medicine in modern clinical practice were put forward. For example,usage dosage(time,area),specific efficacy of external use,early warning index of toxicity,toxic dose,adverse effects,toxic symptoms and corresponding treatment measures all had no reference basis,lacking a systematic toxicity evaluation medication criteria for clinical external use of toxic Chinese medicine. Attention shall be paid to the toxicity of toxic Chinese medicine for external use,and the theory of toxicity evaluation should be established for the external use of " toxic" traditional Chinese medicine under specific conditions. The early warning mechanism for toxic and adverse effects were clarified,and relevant early warning sensitive indicators applicable to clinical use were established in this study to control its risk factors. The study on the mechanism of pharmacodynamics and toxicology of " toxic" traditional Chinese medicine for external use was strengthened to clarify the usage and specific effects of external use. On the basis of this,the study of synergism and reduction of toxicity was carried out to maximize the efficacy of external use of traditional Chinese medicine under specific conditions. A toxicity standard of " toxic" Chinese medicines for external use was put forward,which was of great significance to guide clinical safety,rationality,effectiveness as well as the research and development of new dosage forms for external use of traditional Chinese medicine.

Current state of sewage treatment in China.

The study reported and analyzed the current state of wastewater treatment plants (WWTPs) in urban China from the aspects of scale, treatment processes, sludge handling, geographical distribution, and discharge standards. By 2012, there were 3340 WWTPs in operation in China with a capacity of 1.42 × 10(8) m(3)/d. The number of medium-scale WWTPs (1-10 × 10(4) m(3)/d) counted for 75% of total WWTPs. On average, the chemical oxygen demand (COD) removal efficiencies of small-scale, medium-scale, large-scale and super-large-scale WWTPs were 81, 85.5, 87.5 and 86.5%, respectively. Generally speaking, the nutrients removal instead of COD removal was of concern. As to the different processes, oxidation ditch, anaerobic-anoxic-oxic (A(2)/O) and sequencing batch reactor (SBR) were the mainstream technologies in China. These technologies had minor difference in terms of overall COD removal efficiency. The sludge treatment in WWTPs was basically "thickening-coagulation-mechanical dehydration" and the major disposal method was sanitary landfill in China. The distributions of WWTPs and their utilization showed significant regional characteristics. The sewage treatment capacity of China concentrated on the coastal areas and middle reaches of Yangtze River, which were the economically developed zones. Besides, most WWTPs enforced the Class 1 or Class 2 discharge standards, but few realized wastewater reuse. Finally, existing problems were discussed, including low removal efficiency of nitrogen and phosphorus, emerging contaminants, low reuse of reclaimed water, poor sludge treatment and disposal, low execution standard of effluent, and emissions of greenhouse gas from WWTPs. Suggestions regarding potential technical and administrative measures were given.

Depressive symptoms, conduct problems, and risk for polysubstance use among adolescents: Results from US national surveys.

Polysubstance use in adolescence is a known precursor to chronic substance misuse. Identifying risk factors for polysubstance use is necessary to inform its prevention. The present study examined the association of elevated levels of multiple mental health symptoms with adolescents' engagement in polysubstance use (past month use of alcohol, cigarettes, and marijuana). In a US national sample of 8th, 10th, and 12th grade students from Monitoring the Future surveys, we estimated probability of polysubstance use associated with high levels of depressive symptoms, conduct problems, or both. Depressive symptoms and conduct problems, alone and particularly in combination, were associated with drastically elevated probability of polysubstance use. Adolescents with high levels of both depressive symptoms and conduct problems had the highest probability of polysubstance use. Among 8th and 10th graders, probability of polysubstance use associated with co-occurring mental health problems was significantly higher for girls than boys.
