Mythimna separata walker (Lepidoptera: Noctuidae) is a polyphagous pest of nearly 100 families of more than 300 kinds of food and industrial crops. So far, both nucleotide and protein sequence information has been rarely available in database for M. separata, strictly limiting molecular biology research in this insect species. In this study, we carried out a transcriptome sequencing for M. separata. The sequencing and subsequent bioinformatics analysis yielded 69,238 unigenes, among which 45,227 unigenes were annotated to corresponding functions by blasting with high homologous genes in database, giving annotation rate of 65.32%. Several lepidopteran insects gave best matches with the transcriptome data. To gain insight into the mechanism of insecticide resistance in M. separata, 15 families of genes encoding insecticide resistance-related proteins were investigated. Substantial numbers of unigenes in these families were identified in the transcriptome data, and 17 out of 21 selected unigenes were successfully amplified. Expressions of most of these genes were detected at larval stages and in gut tissue, as was consistent with their putative involvement in insecticide resistance. Our study provides most comprehensive transcriptome data for M. separata to date, and also provides reference sequence information for other Noctuidae family insects.
Aim To examine the literature on Traditional Chinese Medicine (TCM) used in the treatment, prevention and supportive care in patients with COVID‐19. Design A narrative review was performed. Data Sources A systematic and comprehensive search was conducted on both Chinese and English electronic databases: China National Knowledge Infrastructure, Wanfang Data, CINAHL, Embase, Cochrane, PubMed, PsycINFO. Articles published from 1 December 2019 ‐1 April 2020 were included in this review. Review Methods Studies reporting on the treatment and prevention of COVID‐19 using TCM regardless of study designs were included. In addition, grey literatures, including media reports on Chinese government websites or official media websites and treatment guidelines were searched for TCM treatment and prevention on COVID‐19. Results Limited research has been published on the use of TCM for COVID‐19. We qualitatively described and synthesized the published research and current clinical practice on the use of TCM for COVID‐19, and focused on the following areas: TCM treatment used in SARS, MERS, H1N1; TCM treatment plan for COVID‐19; TCM in Prevention and Treatment at Early Stage of COVID‐19; TCM emotional therapy; and personalized TCM treatment plan. Conclusion The combination of western medicine and TCM in treatment, and treatment based on the local condition, isolation, personal protective measures are of great significance for the prevention and treatment of COVID‐19. Relevant laboratory research and clinical evaluation should be continued to collect scientific evidences on the efficacy of TCM. Impact TCM has been used in the treatment and prevention of COVID‐19 in China, and the clinical evidences indicated that TCM regulates immunity and exerts anti‐viral effect simultaneously. This review provides practical recommendation for the policymakers in the selection process of the treatment and preventive measures for the global pandemic of COVID‐19.
Background Clinical nursing education provides opportunities for students to learn in multiple patient care settings, receive appropriate guidance, and foster the development of clinical competence and professionalism. Nurse preceptors guide students to integrate theory into practice, teach clinical skills, assess clinical competencies, and enhance problem-solving and critical thinking skills. Previous research has indicated that the teaching competencies of nurse preceptors can be transferred to students’ clinical learning to enhance their clinical competencies. Objective This study aimed to develop a clinical teaching blended learning (CTBL) program with the aid of web-based clinical pedagogy (WCP) and case-based learning for nurse preceptors and to examine the effectiveness of the CTBL program on nurse preceptors’ clinical teaching competencies, self-efficacies, attitudes toward web-based learning, and blended learning outcomes. Methods A quasi-experimental single-group pretest and posttest design was adopted. A total of 150 nurse preceptors participated in the CTBL program, which was conducted from September 2019 to December 2019. A set of questionnaires, including the clinical teaching competence inventory, preceptor self-efficacy questionnaire, attitudes toward web-based continuing learning survey, and e-learning experience questionnaire, was used to assess the outcomes before and after the CTBL program. Results Compared with the baseline, the participants had significantly higher total mean scores and subdomain scores for clinical teaching competence (mean 129.95, SD 16.38; P<.001), self-efficacy (mean 70.40, SD 9.35; P<.001), attitudes toward web-based continuing learning (mean 84.68, SD 14.76; P<.001), and blended learning outcomes (mean 122.13, SD 14.86; P<.001) after the CTBL program. Conclusions The CTBL program provides a comprehensive coverage of clinical teaching pedagogy and assessment strategies. The combination of the WCP and case-based approach provides a variety of learning modes to fit into the diverse learning needs of the preceptors. The CTBL program allows the preceptors to receive direct feedback from the facilitators during face-to-face sessions. Preceptors also gave feedback that the web-based workload is manageable. This study provides evidence that the CTBL program increases the clinical teaching competencies and self-efficacies of the preceptors and promotes positive attitudes toward web-based learning and better blended learning outcomes. The health care organization can consider the integration of flexible learning and intellect platforms for preceptorship education.
