Insights into the Bioinformatics and Transcriptional Analysis of the Elongator Complexes (ELPs) Gene Family of Wheat: TaELPs Contribute to Wheat Abiotic Stress Tolerance and Leaf Senescence.

Elongator complexes (ELPs) are the protein complexes that promote transcription through histone acetylation in eukaryotic cells and interact with elongating RNA polymerase II (RNAPII). ELPs' role in plant growth and development, signal transduction, and response to biotic and abiotic stresses have been confirmed in model plants. However, the functions of the wheat ELP genes are not well documented. The present study identified 18 members of the ELPs from the wheat genome with a homology search. Further, bioinformatics and transcription patterns in response to different stress conditions were analyzed to dissect their potential regulatory mechanisms in wheat. Gene duplication analysis showed that 18 pairs of ELP paralogous genes were derived from segmental duplication, which was divided into six clades by protein phylogenetic and cluster analysis. The orthologous analysis of wheat TaELP genes showed that TaELP genes may have evolved from orthologous genes of other plant species or closely related plants. Moreover, a variety of cis-acting regulatory elements (CAREs) related to growth and development, hormone response, and biotic and abiotic stresses were identified in the TaELPs' promoter regions. The qRT-PCR analysis showed that the transcription of TaELPs was induced under hormone, salt, and drought stress and during leaf senescence. The TaELP2 gene was silenced with BSMV-VIGS, and TaELP2 was preliminarily verified to be involved in the regulation of wheat leaf senescence. Overall, TaELP genes might be regulated by hormone signaling pathways and response to abiotic stress and leaf senescence, which could be investigated further as potential candidate genes for wheat abiotic stress tolerance and yield improvement.

Effect of five-elements music therapy combined with Baduanjin qigong on patients with mild COVID-19.

Background: To investigate the physical and psychological effects of five-element music therapy combined with Baduanjin qigong treatment on inpatients with mild coronavirus disease 2019 (COVID-19) in Wuhan. Methods: A mixed-methods study was used. In the quantitative study, a randomized controlled trial was performed on 40 study participants divided into a control group (n = 20) and an intervention group (n = 20). The Self-rating Anxiety Scale, Self-rating Depression Scale and Pittsburgh Sleep Quality Index were compared. For qualitative analysis, it adopted purposive sampling method, 13 patients of different ages from 18 to 60 years old and different exercise behavior were selected as the participants from the intervention group. A semi-structured interview method was used to collect data, and the content analysis method was used for data analysis. An interview outline was developed to assess the psychological condition and personal functional-exercise behavior of patients. Results: In the quantitative study, the anxiety self-scores and depression self-scores of patients in intervention group were significantly lower compared with control group after treatment (p < .05). The sleep quality of intervention group was significantly improved compared with control group (p < .001). Participants in the qualitative study responded to questions posed through semi-structured interviews. The effect of intervention was good, which has been supported and recognized by patients. Conclusion: The treatment of five-element music therapy combined with Baduanjin qigong on patients with mild COVID-19 alleviated anxiety and depression, and improved sleep quality, which was beneficial to the patients' physical and psychological recovery.

Comparative efficacy of 12 non-drug interventions on non-specific chronic low back pain in nurses: A systematic review and network meta-analysis.

BACKGROUND: Many non-drug interventions for decreasing non-specific chronic low back pain (NSCLBP) in nurses have been extensively studied, but the most effective approach is still unclear. OBJECTIVE: This systematic review and network meta-analysis evaluated the efficacies of 12 non-drug interventions in reducing NSCLBP in nurses. METHODS: PubMed, ScienceDirect, Web of Science, Cochrane, EMBASE, CINAHL, Medline, WANFANG, VIP, China Knowledge Integrated, and SinoMed were searched from their establishment to July 2019. Randomized controlled trials (RCTs) comparing non-drug interventions for NSCLBP in nurses were included and analyzed using Stata v15 statistical software. RESULTS: A total of 31 RCTs (n= 7116) and 12 non-drug interventions were included. The first three results with the highest surface areas under the curve ranking area (SUCRAs) were low back exercise plus healthy education, single low back exercise, and yoga (SUCRAs: 79.4%, 76.2%, and 75.1%, respectively). In addition, single yoga was inferior to protective equipment (standardized mean difference [SMD] = 3.88, 95% confidence interval [CI]: 0.92 to 6.84) and multidisciplinary intervention (SMD =-4.06, 95% CI: -7.33 to -0.78). CONCLUSIONS: Low back exercise plus health education may be the best approach to reduce NSCLBP in nurses. Considering the heterogeneity, our findings need to be confirmed in future multicenter large sample RCTs in different countries.
