miR-342-5p targets CTNNBIP1 to promote enterovirus 71 replication.

OBJECTIVE: The aim of this research was to explore the role of miR-342-5p in EV71 replication. METHODS: Peritoneal injection of EV71 (107 TCID50/mL) at 50, 100, and 150 µL was conducted to infect 12-day-old suckling mice (n = 10 per group), and clinical scores and survival rates were recorded during a 6-day trial duration and followed by transcriptome sequencing of collected spinal cord tissues. The differential miRNAs and target genes of the infected and uninfected EV71 mice were analyzed. The miR-342 and CTNNBIP1 binding sites were detected using a dual luciferase reporter assay. Cell viability was detected by CCK-8. RT-qPCR, Western blot, immunofluorescence, and immunohistochemistry assays were conducted to detect VP1 protein levels. RESULTS: Transcriptome sequencing analyses know that the Wnt pathway played a role in EV71 infection, and the CTNNBIP1 gene in this pathway was the target gene of miR-342-5p. Whether in HMC3 cells or in the spinal cord tissue from the suckling mice, high levels of miR-342-5p markedly promoted EV71 VP1 mRNA and protein expression, elevated TNF-α, IL-6, and IL-10 levels, and inhibited IFN-ß levels. In addition, highly expressed miR-342-5p destroyed neuronal structure in spinal cord tissues and reduced the number of glial cells. Highly expressed CTNNBIP1 blocked the promotion of miR-342-5p in EV71 replication, and inhibited TNF-α, IL-6, and IL-10 levels, whereas elevated IFN-ß levels. This mechanism is that miR-342-5p can target the CTNNBIP1 3' UTR region, inhibit its expression and reduce its binding to CTNNB1, thus enhancing the interaction between CTNNB1 and TCF4 and activating the Wnt pathway-mediated type I interferon response. CONCLUSION: In nerve cells and tissues, the overexpression of miR-342-5p promoted the replication of EV71 and attenuated the innate immune response to antiviral disease via Wnt/CTNNB1 signaling pathway.

[Clinical observation on syndrome-differentiation acupuncture combined with rehabilitation training for autism spectrum disorder].

OBJECTIVE: To compare the clinical efficacy and safety between syndrome-differentiation acupuncture combined with rehabilitation training and simple rehabilitation training for children with autism spectrum disorder (ASD). METHODS: A total of 60 children with ASD were randomly divided into an observation group and a control group, 30 cases in each group. In the control group, routine rehabilitation training was applied; in the observation group, syndrome-differentiation acupuncture (the main points were Baihui [GV 20], Dingshenzhen, Niesanzhen, etc., the supplementary acupoints were selected according to syndrome-differentiation) combined with rehabilitation training were applied, all the treatments were given once a day, 5-day continuous treatment with 2-day interval, 12 weeks were required. Before treatment and after 6, 12 weeks of treatment, the autism treatment evaluation checklist (ATEC), childhood autism rating scale (CARS) and autism behavior checklist (ABC) scores were observed, the therapeutic effect and safety were evaluated in the two groups. RESULTS: After 6 and 12 weeks of treatment, except for the sensory perception score after 6 weeks of treatment in the control group, the item scores and total scores of ATEC, CARS scores and ABC scores were decreased compared with those before treatment in the two groups (P<0.05). After 6 weeks of treatment, the social score and total score of ATEC, CARS score in the observation group were lower than those in the control group (P<0.05); after 12 weeks of treatment, the item scores and total score of ATEC, CARS score and ABC score in the observation group were lower than those in the control group (P<0.05). The total effective rate in the observation group was 80.0% (24/30), which was higher than 56.7% (17/30) in the control group (P<0.05). There was no serious adverse reactions in the two groups, and there was no significant difference in the incidence rate of adverse reactions between the two groups (P>0.05). CONCLUSION: Syndrome-differentiation acupuncture combined with rehabilitation training could improve the core symptoms in children with ASD, especially sensory perception and social ability, and with good safety, which is superior to simple rehabilitation training.

Efficacy and safety of acupuncture on childhood attention deficit hyperactivity disorder: A protocol for systematic review and meta-analysis.

INTRODUCTION: The purpose of this paper is to evaluate the efficacy and safety of acupuncture in the treatment of childhood attention deficit hyperactivity disorder (ADHD). METHODS AND ANALYSIS: We will electronically search PubMed, Medline, Embase, Web of Science, the Cochrane Central Register of Controlled Trial, China National Knowledge Infrastructure, China Biomedical Literature Database, China Science Journal Database, and Wan-fang Database from their inception. Also, we will manually retrieve other resources, including reference lists of identified publications, conference articles, and grey literature. The clinical randomized controlled trials or quasi-randomized controlled trials related to acupuncture treating pediatric ADHD will be included in the study. The language is limited to Chinese and English. Research selection, data extraction, and research quality assessment will be independently completed by 2 researchers. Data were synthesized by using a fixed effect model or random effect model depend on the heterogeneity test. The scores of Revised Conners' Parent Rating Scale (CPRS-R), Conners Teacher Rating Scale (CTRS-R), and Child Behavior Checklist (CBCL) will be the primary outcomes. Besides, the scores of the Conners Continuous Performance Test, Internal Restlessness Scale, and Behavior Assessment System for Children (BASC), and the possible adverse events will also be assessed as secondary outcomes. RevMan V.5.3 statistical software will be used for meta-analysis, and the level of evidence will be assessed by Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Continuous data will be expressed in the form of weighted mean difference or standardized mean difference with 95% confidence intervals (CIs), while dichotomous data will be expressed in the form of relative risk with 95% CIs. ETHICS AND DISSEMINATION: The protocol of this systematic review (SR) does not require ethical approval because it does not involve humans. We will publish this article in peer-reviewed journals and presented at relevant conferences. SYSTEMATIC REVIEW REGISTRATION: OSF Registries, DOI: 10.17605/OSF.IO/XVYP9 (https://osf.io/xvyp9).
