INTRODUCTION: Adverse childhood experiences (ACEs) are associated with significant long-term impacts, yet few interventions specifically target ACE exposure, especially in Asian populations. Anchor, Singapore's first home visitation programme, addresses maltreat-ment among preschool children. This study evaluated Anchor's impact on children's developmental and behavioural outcomes. METHOD: We conducted a prospective evaluation of children under 4 years assessed for maltreatment from November 2019 to July 2023. Developmental and behavioural progress was measured every 6 months using the Ages and Stages Questionnaires (ASQ-3) and ASQ:Social-Emotional (ASQ:SE-2), and annually using the Child Behaviour Checklist (CBCL). RESULTS: The results of 125 children (mean age 20.0 months, 48% female) were analysed. The mean length of stay in programme was 21.2 (7.3) months. At baseline, 92 (73.6%) children were at risk of develop-mental delay and 25 (31.7%) children aged ≥18 months had behavioural concerns. The programme was associated with significant improvements in gross motor (P=0.002) and fine motor (P=0.001) domains of the ASQ-3 and internalising problem scale (P=0.001) of the CBCL. CONCLUSION Anchor effectively enhances develop-mental and behavioural outcomes for children exposed to maltreatment. Targeted early intervention through such programmes can mitigate adverse impacts, optimising developmental trajectories and potentially reducing the long-term clinical and economic burdens associated with ACEs.

Objective To investigate the effect of silenced RBM8A gene on the biological behavior (proliferation, migration, and apoptosis) of human endometrial cancer HEC-1A cells and its possible mechanism. Methods The hairpin shRNA targeted by the RBM8A gene was designed, and the best shRNA silencing fragment was screened. The recombinant lentiviral interference vector carrying the target gene was constructed and used to infect HEC-1A cells. Cells with stable knockdown of RBM8A gene were screened by puromycin as the experimental group (shRBM8A), while the shRNA of nonsense sequence was designed as the control group (shControl). CCK-8 method was used to detect cell proliferation, and flow cytometry was used to detect cell apoptosis. Transwell assay was used to detect cell migration and invasion. Western blot was used to analyze the expression of apoptosis-related proteins and EMT signal transduction pathway related proteins. Results In comparison with the shControl group, after RBM8A knockdown, HEC-1A cell proliferation was reduced, apoptosis was increased, migration and invasion ability were significantly inhibited (P < 0.05), the expression of apoptosis-related proteins cleaved caspase 9 and caspase 3 increased, EMT-related protein E-cadherin expression increased, and Vimentin expression decreased. Conclusion RBM8A gene silencing can inhibit the proliferation, migration, and invasion and promote the apoptosis of endometrial cancer cells. The inhibition of EMT signal transduction pathway may be its mechanism.

Estrogen impacts neural development; meanwhile, it has a protective effect on the brain. Bisphenols, primarily bisphenol A (BPA), can exert estrogen-like or estrogen-interfering effects by binding with estrogen receptors. Extensive studies have suggested that neurobehavioral problems, such as anxiety and depression, can be caused by exposure to BPA during neural development. Increasing attention has been paid to the effects on learning and memory of BPA exposure at different developmental stages and in adulthood. Further research is required to elucidate whether BPA increases the risk of neurodegenerative diseases and the underlying mechanisms, as well as to assess whether BPA analogs, such as bisphenol S and bisphenol F, influence the nervous system.

The current linear economy model relies on fossil energy and increases CO₂ emissions, which contributes to global warming and environmental pollution. Therefore, there is an urgent need to develop and deploy technologies for carbon capture and utilization to establish a circular economy. The use of acetogens for C1-gas (CO and CO₂) conversion is a promising technology due to high metabolic flexibility, product selectivity, and diversity of the products including chemicals and fuels. This review focuses on the physiological and metabolic mechanisms, genetic and metabolic engineering modifications, fermentation process optimization, and carbon atom economy in the process of C1-gas conversion by acetogens, with the aim to facilitate the industrial scale-up and carbon negative production through acetogen gas fermentation.

Objective:To detect the expression of miR-378 in cervical cancer and investigate its effects on the proliferation and invasion of cancer cells as well as the underlying mechanism.Methods:A total of 185 cervical tissue samples of women who received gynecological examination in Qilu Hospital of Shandong University from January 2012 to January 2016 were included in this study. Reverse transcription-quantitative polymerase chain reaction was performed to determine the expression of miR-378 in cervical tissue and C-33A cells. Western blot assay was performed to detect the expression of different cancer genes ATG12, CCND1 and pRb in C-33A cells. BrdU cell proliferation and Transwell invasion assay were performed to determine cell proliferation and invasion. Target Scan was used to predict and screen miR-378 gene targets and verified by a dual-luciferase reporter assay system.Results:The expression of miR-378 in cervical intraepithelial neoplasia (CIN) III lesioned tissue and cervical cancer tissue was significantly higher than that in normal cervical tissues ( F = 103.091, t = 9.381, 8.936, both P < 0.05). The expression of miR-378 in cervical cancer tissues with positive lymph node metastasis was significantly higher than that in cervical cancer tissues with negative lymph node metastasis ( t = 1.007, P < 0.01). The overexpression of miR-378 in cervical cancer tissues significantly promoted the migration and invasion of C-33A cells ( t = 5.285, P < 0.05), while low expression of miR-378 in cervical cancer tissues significantly inhibited the migration and invasion of HeLa cells ( t = 2.941, P < 0.05). The overexpression of miR-378 in C-33A cells significantly decreased the expression of ATG12, CCND1and pRb ( t = 1.382, 1.431 and 2.086, all P < 0.05). The low expression of miR-378 in C-33A cells significantly increased the expression of ATG12, CCND1 and pRb ( t = 3.961, 3.062 and 2.894, all P < 0.05). Conclusion:miR-378 can greatly promote the metastasis of cervical cancer cells. ATG12, as a direct target of miR-378, provides new insights into the molecular mechanism underlying cervical cancer pathology and therapeutic target.

OBJECTIVES: To study the transcriptomic changes of astrocytes in the brain of rats exposed to methamphetamine (METH) and its possible mechanism in neurotoxicity. METHODS: The rats were intraperitoneally injected with METH (15 mg/kg) every 12 h for 8 times in total to establish the subacute rat model of METH. After the model was successfully established, the striatum was extracted, and astrocytes were separated by the magnetic bead method. Transcriptome sequencing was performed on selected astrocytes, and the differentially expressed genes were analyzed by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. RESULTS: A total of 876 differentially expressed genes were obtained by transcriptome sequencing, including 321 up-regulated genes and 555 down-regulated genes. GO analysis revealed that differentially expressed genes were mainly concentrated in cell structure, biological process regulation, extracellular matrix and organelle functions. KEGG pathway enrichment analysis showed that steroids biosynthesis, fatty acid biosynthesis, peroxisome proliferators-activated receptor (PPAR), adenosine 5'-monophosphate-activated protein kinase (AMPK) and other signaling pathways were significantly changed. CONCLUSIONS METH can cause structural changes of astrocytes through multiple targets, among which cellular structure, steroids biosynthesis and fatty acid biosynthesis may play an important role in nerve injury, providing a new idea for forensic identification of METH related death.

Objective:To explore the effect of the care and nursing practice plan based on the timing theory in primary caregivers of infants with infantile spasms.Methods:From July 2019 to June 2020, 80 infants with infantile spasm and 80 primary caregivers in the Department of Neurology of Hunan Children's Hospital were selected as the research object. All infants with infantile spasms were numbered according to the time of admission. The odd-numbered infants were admitted to the First Department of Neurology as the observation group, and the even-numbered children were admitted to the Second Department of Neurology as the control group, with 40 infants and 40 primary caregivers in each group. The control group carried out conventional treatment and nursing, and the observation group implemented a care and nursing practice plan based on the timing theory on the basis of the control group. Before and after the intervention, the Caring Ability Inventory (CAI) , Family Caregiver Task Inventory (FCTI) , Caregiver Burden Inventory (CBI) , and Gesell Developmental Schedules (GDS) were used to evaluate the caring ability, caregiving ability, care load of the primary caregivers of the two groups of infants, and the cognition function of the two groups of infants.Results:After the intervention, the total CAI scores of the primary caregivers in the observation group were higher than those before intervention and those in the control group after the intervention, and the total scores of FCTI and CBI were lower than those before intervention and those in the control group after the intervention, and the differences were statistically significant ( P<0.05) . After the intervention, the developmental quotient (DQ) values of the five energy areas of GDS in the observation group were higher than those before the intervention, and the DQ values of the three energy areas of gross motor, fine motor, and language were higher than those of the control group after the intervention, and the differences were statistically significant ( P<0.05) . Conclusions:The care and nursing practice plan based on the timing theory can improve the caring ability and caregiving ability of the main caregivers of children with infantile spasms, reduce the care load, and improve the cognitive function of the children.
