OBJECTIVES: To study the impact of family socioeconomic status on children's reading fluency and the chain mediation effect of family reading environment and children's living and learning styles in this relationship. METHODS: A total of 473 children from grades 2 to 6 in two primary schools in Nanjing were selected through stratified random sampling. The children's reading fluency was assessed, and a questionnaire was used to collect information on family socioeconomic status, family reading environment, and children's living and learning styles. The mediation model was established using the Process macro in SPSS, and the Bootstrap method was employed to test the significance of the mediation effects. RESULTS: Family socioeconomic status, family reading environment, and children's living and learning styles were significantly positively correlated with reading fluency (P<0.001). The family reading environment and children's living and learning styles mediated the relationship between family socioeconomic status and children's reading fluency. Specifically, the independent mediation effect of family reading environment accounted for 11.02% of the total effect, while the independent mediation effect of children's living and learning styles accounted for 10.79%. The chain mediation effect of family reading environment and children's living and learning styles accounted for 7.41% of the total effect. CONCLUSIONS Family socioeconomic status can affect children's reading fluency through three pathways: family reading environment, children's living and learning styles, and the chain mediation effect of family reading environment and children's living and learning styles.

OBJECTIVES: To study the impact of the home literacy environment on children's emotional regulation skills and the mediating role of the parent-child relationship between them. METHODS: A stratified cluster sampling approach was employed to select 1 626 preschool children from five kindergartens in Nanjing. Questionnaires were used to collect detailed information on the home literacy environment, children's emotional regulation skills, and the parent-child relationship. A mediation model was established using the Process program in SPSS macro, and the significance of the mediation effect was tested using the Bootstrap method. RESULTS: The findings revealed a positive correlation between the home literacy environment and children's emotional regulation skills (r=0.217, P<0.001), as well as parent-child intimacy (r=0.065, P<0.01). Conversely, a negative correlation was found between the home literacy environment and parent-child conflict (r=-0.129, P<0.001). Additionally, parent-child conflict demonstrated a negative correlation with children's emotional regulation skills (r=-0.443, P<0.001), while parent-child intimacy exhibited a positive correlation (r=0.247, P<0.001). The home literacy environment exerted a significant direct effect on children's emotional regulation skills (β=0.162, P<0.001), and the mediating effect of the parent-child relationship accounted for 25.54% of the total effect. CONCLUSIONS The home literacy environment significantly influences children's emotional regulation skills, with the parent-child relationship partially mediating this relationship.

With the development of modern sequencing techniques and bioinformatics, genomes that were once thought to be noncoding have been found to encode abundant functional micropeptides (miPs), a kind of small polypeptides. Although miPs are difficult to analyze and identify, a number of studies have begun to focus on them. More and more miPs have been revealed as essential for energy metabolism homeostasis, immune regulation, and tumor growth and development. Many reports have shown that miPs are especially essential for regulating glucose and lipid metabolism and regulating mitochondrial function. MiPs are also involved in the progression of related diseases. This paper reviews the sources and identification of miPs, as well as the functional significance of miPs for metabolism-related diseases, with the aim of revealing their potential clinical applications.

Objective: This study aimed to identify internal ribosome entry sites (IRESs) in the open reading frame (ORF) of the Coxsackievirus B3 (CVB3) genome. Methods: The sequences of P1, P2, or P3 of the CVB3 genome or the truncated sequences from each antithymocyte globulin (ATG) to the end of the P1, P2, or P3 gene were inserted into the pEGFP-N1 vector. After transfection, possible IRES-dependent green fluorescent protein (GFP)-fused proteins were detected by anti-GFP western blotting. The sequences of possible IRESs were inserted into specific Fluc/Rluc bicistronic vectors, in which the potential IRESs were determined according to the Fluc/Rluc activity ratio. Expression of Fluc and Rluc mRNA of the bicistronic vector was detected by RT-qPCR. Results: After transfection of full length or truncated sequences of the P1, P2, or P3 plasmids, six GFP-fused protein bands in P1, six bands in P2 and nine bands in P3 were detected through western blotting. Two IRESs in VP2 (1461-1646 nt) and VP1 (2784-2983 nt) of P1; one IRES in 2C (4119-4564 nt) of P2; and two IRESs in 3C (5634-5834 nt) and 3D (6870-7087 nt) of P3 were identified according to Fluc/Rluc activity ratio. The cryptic promoter was also excluded by RT-qPCR. Conclusion Five IRESs are present in the CVB3 coding region.

Reynoutria japonica Houtt., belonging to Polygoneae of Polygonaceae, is a Chinese medicinal herb with the functions of draining dampness and relieving jaundice, clearing heat and detoxifying, dispersing blood stasis and relieving pain, and relieving cough and resolving phlegm. In this study, we carried out high-throughput sequencing for the chloroplast genome sequences of five cultivars of R. japonica and analyzed the genome structure and variations. The chloroplast genomes of the five R. japonica cultivars had two sizes (163 376 bp and 163 371 bp) and a typical circular tetrad structure composed of a large single-copy (LSC) region of 85 784 bp, a small single-copy (SSC) region of 18 616 bp, and a pair of inverted repeat (IR) regions (IRa/IRb) which are spaced apart. A total of 161 genes were obtained by annotation, which consisted of 106 protein-coding genes, 10 rRNA-coding genes, and 45 tRNA-coding genes. The total GC content was 36.7%. Specifically, the GC content in the LSC, SSC, and IR regions were 34.8%, 30.7%, and 42.7%, respectively. Comparison of the whole chloroplast genome among the five cultivars showed that trnk-UUU, rpoC1, petD, rpl16, ndhA, and rpl12 in coding regions had sequence variations. In the phylogenetic tree constructed for the 11 samples of Polygoneae, the five cultivars of R. japonica clustered into one clade near the root and was a sister group of Fallopia multiflora (Thunb.).

Critical appraisal is the process of reading published research to make a judgement on its scientific value (validity), and to consider how its results can be applied in family and community practice (applicability). There are four main elements of critical appraisal in EBFP i.e., relevance, validity, results, and applicability. Some family practitioners are not so comfortable with appraisal because of their poor background in research. But we developed the guide questions for critical appraisal simple and provide advice on what and where to look for it in the published evidence.

Chinese, as a logographic language, fundamentally differs from alphabetic languages like English. Previous neuroimaging studies have mainly focused on alphabetic languages, while the exploration of Chinese reading is still an emerging and fast-growing research field. Recently, a growing number of neuroimaging studies have explored the neural circuit of Chinese reading. Here, we summarize previous research on Chinese reading from a connectomic perspective. Converging evidence indicates that the left middle frontal gyrus is a specialized hub region that connects the ventral with dorsal pathways for Chinese reading. Notably, the orthography-to-phonology and orthography-to-semantics mapping, mainly processed in the ventral pathway, are more specific during Chinese reading. Besides, in addition to the left-lateralized language-related regions, reading pathways in the right hemisphere also play an important role in Chinese reading. Throughout, we comprehensively review prior findings and emphasize several challenging issues to be explored in future work.

Cleft lip and/or palate (CLP) are the most common craniofacial malformations in humans. Speech problems often persist even after cleft repair, such that follow-up articulation training is usually required. However, the neural mechanism behind effective articulation training remains largely unknown. We used fMRI to investigate the differences in brain activation, functional connectivity, and effective connectivity across CLP patients with and without articulation training and matched normal participants. We found that training promoted task-related brain activation among the articulation-related brain networks, as well as the global attributes and nodal efficiency in the functional-connectivity-based graph of the network. Our results reveal the neural correlates of effective articulation training in CLP patients, and this could contribute to the future improvement of the post-repair articulation training program.

African swine fever virus (ASFV) infection leads to a mortality rate of up to 100%, causing devastating disasters to the pig industry. Understanding the ASFV infection and replication is therefore of great importance. ASFV has more than 150 open reading frames, among which the inner coat protein p17 encoded by the D117L gene is involved in the formation of the icosahedral structure of the virus. However, little is known about the mechanism how p17 regulates host cell function. In this study, the potential host proteins interacting with ASFV p17 were screened by immunoprecipitation technique combined with protein profiling analysis. The interactions of p17 with mitochondrial membrane protein TOMM70 and heat shock protein HSPA8 were confirmed by co-immunoprecipitation technique and laser confocal experiments. This study provides important information for further exploring the function of p17 during ASFV infection.

Long non-coding RNA (lncRNA) refers to non-coding RNA longer than 200 nt, with one or more short open reading frames (sORF), which encode functional micro-peptides. These functional micro-peptides often play key roles in various biological processes, such as Ca²⁺ transport, mitochondrial metabolism, myocyte fusion, cellular senescence and others. At the same time, these biological processes play a key role in the regulation of body homeostasis, diseases and cancers development and progression, embryonic development and other important physiological processes. Therefore, studying the potential regulatory mechanisms of micro-peptides encoded by lncRNA in organisms will help to further elucidate the potential regulatory processes in organisms. Furthermore, it will provide a new theoretical basis for the subsequent targeted treatment of diseases and improvement of animal growth performance. This review summarizes the latest research progress in the field of lncRNA-encoded micro-peptides, as well as the progress in the fields of muscle physiological regulation, inflammation and immunity, common human cancers, and embryonic development. Finally, the challenges of lncRNA-encoded micro-peptides are briefly described, with the aim to facilitate subsequent in-depth research on micro-peptides.
