Abstract
This study explored the coronavirus disease 2019 (COVID-19) vaccination coverage among children with epilepsy (CwE), factors affecting vaccination coverage, and the effect of COVID-19 vaccines on epilepsy after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. A questionnaire was administered to CwE and their parents at the Pediatric Neurology Clinic of the Second Affiliated Hospital of Xi'an Jiaotong University between December 12, 2022, and February 28, 2023. Data were analyzed using the t-tests, chi-square tests, and logistic regression. The analysis included 250 CwE who responded to the survey; of these, 152 (60.8%) had been vaccinated against COVID-19. COVID-19 vaccine hesitancy in parents whose CwE were not vaccinated was mostly due to concerns of vaccine-related exacerbation of seizures and of vaccine-related adverse reactions (44.30% and 41.90% of the respondents, respectively). Univariate analysis showed that vaccination and number of doses of vaccine did not affect seizure incidence within 1 month of SARS-CoV-2 infection. Logistic regression analysis showed that CwE below primary school age, and those taking two or more antiseizure medication (ASMs) were less likely to be vaccinated (p = 0.007). Conclusion: The primary reasons for vaccine hesitancy among parents of unvaccinated CwE were concerns regarding seizure exacerbation and adverse reactions following COVID-19 vaccination. CwE who were below primary school age and those who took two or more ASMs were less likely to be vaccinated. Addressing parents' concerns is necessary to build their confidence in COVID-19 vaccines and ensure that CwE are vaccinated. What is Known: • People with epilepsy have a higher risk of severe and fatal COVID-19 than those without epilepsy but, despite this, COVID-19 vaccination coverage is considerably lower in people with epilepsy than in people without epilepsy. What is New: • In unvaccinated children with epilepsy, the foremost reasons for COVID-19 vaccine hesitancy among parents were concerns about seizure exacerbation and vaccine-related adverse reactions. • Vaccination and number of doses of vaccine did not exacerbate seizures in children with epilepsy, those below primary school level and those taking two or more antiseizure medications were less likely to be vaccinated.

Abstract
OBJECTIVE To investigate the mechanism by which Chinese medicine Shengmai Yin (SMY) reverses epithelial-mesenchymal transition (EMT) through lipocalin-2 (LCN2) in nasopharyngeal carcinoma (NPC) cells CNE-2R. METHODS Morphological changes in EMT in CNE-2R cells were observed under a microscope, and the expressions of EMT markers were detected using quantitative real-time PCR (RT-qPCR) and Western blot assays. Through the Gene Expression Omnibus dataset and text mining, LCN2 was found to be highly related to radiation resistance and EMT in NPC. The expressions of LCN2 and EMT markers following SMY treatment (50 and 100 µ g/mL) were detected by RT-qPCR and Western blot assays in vitro. Cell proliferation, migration, and invasion abilities were measured using colony formation, wound healing, and transwell invasion assays, respectively. The inhibitory effect of SMY in vivo was determined by observing a zebrafish xenograft model with a fluorescent label. RESULTS The CNE-2R cells showed EMT transition and high expression of LCN2, and the use of SMY (5, 10 and 20 µ g/mL) reduced the expression of LCN2 and reversed the EMT in the CNE-2R cells. Compared to that of the CNE-2R group, the proliferation, migration, and invasion abilities of SMY high-concentration group were weakened (P<0.05). Moreover, SMY mediated tumor growth and metastasis in a dose-dependent manner in a zebrafish xenograft model, which was consistent with the in vitro results. CONCLUSIONS SMY can reverse the EMT process of CNE-2R cells, which may be related to its inhibition of LCN2 expression. Therefore, LCN2 may be a potential diagnostic marker and therapeutic target in patients with NPC.

Abstract
Shengmai Yin (SMY) is a Chinese herbal decoction that effectively alleviates the side effects of radiotherapy in various cancers and helps achieve radiotherapy's clinical efficacy. In this study, we explored the interaction mechanism among SMY, DNA methylation, and nasopharyngeal carcinoma (NPC). We identified differences in DNA methylation levels in NPC CNE-2 cells and its radioresistant cells (CNE-2R) using the methylated DNA immunoprecipitation array and found that CNE-2R cells showed genome-wide changes in methylation status towards a state of hypomethylation. SMY may restore its original DNA methylation status, and thus, enhance radiosensitivity. Furthermore, we confirmed that the differential gene Tenascin-C (TNC) was overexpressed in CNE-2R cells and that SMY downregulated TNC expression. This downregulation of TNC inhibited NPC cell radiation resistance, migration, and invasion. Furthermore, we found that TNC was hypomethylated in CNE-2R cells and partially restored to a hypermethylated state after SMY intervention. DNA methyltransferases 3a may be the key protein in DNA methylation of TNC. A significant difference in the genome-wide methylation status between Nasopharyngeal carcinoma CNE-2 cells and its radioresistant strain. Shengmai Yin-mediated enhancement of radiosensitivity might be mediated by restoration of its original DNA methylation status. Tenascin-C was downregulated and restored to partially hypermethylated in CNE-2R after Shengmai Yin intervention, DNMT3a maybe the key protein of DNA methylation of TNC. The downregulation of TNC inhibited NPC cell radiation resistance, migration and invasion.

Abstract
The development of radioresistance by nasopharyngeal carcinoma (NPC) cells almost always results in tumor recurrence and metastasis, making clinical treatment of the disease difficult. In this study, the mechanism of radioresistance in NPC cells was investigated. First, a gene array and quantitative reverse-transcription-PCR assays were used to screen for genes exhibiting significantly altered expression in the DNA damage signaling pathway. Based on those results, GADD45G was further studied in the context of radioresistance. A GADD45G-knockout NPC cell line (CNE-2R-KO) was constructed using CRISPR-Cas9 technology and used for a comparison of differences in radioresistance with other radiosensitive and radioresistant NPC cells, as evaluated using colony formation assays. Cell cycle changes were observed using flow cytometry. Cell proliferation and migration were measured using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide and wound healing assays, respectively. The sequencing results revealed the successful construction of the CNE-2R-KO cell line, the radiosensitivity of which was higher than that of its parent radioresistant cell line owing to the GADD45G knockout. This was likely related to the increase in the number of cells in the G1 phase and decrease in those in the S1 phase as well as the increased cell proliferation rate and decreased migratory ability. GADD45G is associated with radioresistance in NPC cells and likely has a role in the occurrence and metastasis of NPC.

Abstract
For tetraphenylethene (TPE) derivatives, it is difficult to determine the arrangement of the molecules in the aggregation state because disordered aggregation usually occurs. To solve the problem, we have explored a novel and facile strategy to investigate the aggregation mode of a TPE derivative framework in which the two neighboring ortho carbons of two phenyl moieties at the same ethylene carbon were linked with an alkoxyl chain (C4) (denoted as TPEC4). The XRD measurements on the particles obtained in a DMSO/H2O mixture (fw = 60%) showed sharp peaks which is consistent with the simulated XRD patterns on the basis of a single crystal structure of TPEC4, indicating well-ordered molecular packing in the aggregated state. The CH/π-interaction and solvophobicity driven self-assembly behaviour of the compound was observed in the DMSO/H2O mixture. A face to face molecular packing structure that arises from quadruple intermolecular CH/π-interactions of the tetraphenylethylenes is the key motif for self-assembly in solution. The unique blue-red shifted emission in the DMSO/H2O mixture associated with aggregated behaviour of the compound was also investigated. This discovery will provide the basis for theoretical research and the rational design of TPE-based luminogens. The CH/π interaction can drive the TPE motif to adopt a face-to-face crystalline packing in this TPE benzene rings linked with an alkoxyl chain (C4) during aggregation.![]()

Abstract
BACKGROUND Curcumin (CUR) is a natural diarylheptanoid with marked anti-tumor activities. Recent investigations demonstrate that CUR combines with some other phytochemicals exerts advantages over its single application manifested as lower toxicity, higher efficacy or more significant reversal of multidrug resistance. PURPOSE This study aimed to elucidate a new biflavonoid (wikstroflavone B, WFB) isolated from Wikstroemia indica and to assess the synergistic inhibition of combined CUR and WFB (CUR/WFB) on human nasopharyngeal carcinoma (NPC) cell lines proliferation and metastasis. METHODS WFB was obtained through sequential chromatographic methods including silica gel, Sephadex LH-20 and preparative HPLC. Its structure was determined by HRESIMS, 1D and 2D NMR spectroscopic analysis. The absolute configuration of WFB was assigned through comparison of experimental and calculated optical rotation (OR) values. Changes in cellular viability, migration and invasion were assessed by MTT, colony formation, wound healing and Transwell assays. The nature of synergistic interaction of CUR/WFB was determined through the combination index (CI) method under the median-effect analysis. Expression levels of indicated mRNAs and proteins were measured by qRT-PCR and Western blotting assays, respectively. RESULTS WFB was isolated and structural elucidated. Compared with CUR or WFB used alone, CUR/WFB treatment inhibited more effectively on the cell viability, colony formation, cell migration and invasion. Both CI and dose reduction index (DRI) values indicated the significant synergistic effects existed between CUR and WFB. Besides, CUR/WFB showed the marked modulation on the genes involved in cell proliferation (survivin, cyclin D1, p53 and p21) and metastasis (MMP-2, MMP-9 and FAK). CUR/WFB treatment was also found to restrain the phosphorylation of FAK and STAT3 proteins. When pretreatment with a FAK inhibitor, the cell viability and metastasis were significantly attenuated. CONCLUSION The results indicate that WFB can synergistically increase the inhibitory effects of CUR on NPC cells proliferation and metastasis, and these findings may afford a rational approach for developing the antitumor medications.

Abstract
Circular RNAs (circRNAs) are involved in cancer development via inhibition of miRNAs, which are associated with differentiation, proliferation, migration, and carcinogenicity. Curcumin has antioxidant and anti-cancer properties, and it has also been used as a radiosensitizer. In this study, we explored the potential relationships among curcumin, circRNAs, and nasopharyngeal carcinoma (NPC). We compared the differences in circRNA levels in NPC cell lines after radiotherapy and after treatment with curcumin, using a high-throughput microarray. Further, a circRNA-miRNA-mRNA interaction network between radiation resistance NPC cell lines and tumor stem cells was constructed by applying bioinformatics. Finally, it was demonstrated by reverse transcription-quantitative polymerase chain reaction assay and wound healing assay that curcumin could enhance radiosensitization of NPC cell lines via mediating regulation of tumor stem-like cells by the "hsa_circRNA_102115"-"hsa-miR-335-3p"-"MAPK1" interaction network.

Abstract
Ubiquitin Specific Peptidase 16 (USP16) has been reported to contribute to somatic stem-cell defects in Down syndrome. However, how this gene being regulated is largely unknown. To study the mechanism underlying USP16 gene expression, USP16 gene promoter was cloned and analyzed by luciferase assay. We identified that the 5′ flanking region (− 1856 bp ~ + 468 bp) of the human USP16 gene contained the functional promotor to control its transcription. Three bona fide NFκB binding sites were found in USP16 promoter. We showed that p65 overexpression enhanced endogenous USP16 mRNA level. Furthermore, LPS and TNFα, strong activators of the NFκB pathway, upregulated the USP16 transcription. Our data demonstrate that USP16 gene expression is tightly regulated at transcription level. NFκB signaling regulates the human USP16 gene expression through three cis-acting elements. The results provide novel insights into a potential role of dysregulation of USP16 expression in Alzheimer’s dementia in Down Syndrome.

Abstract
Circular RNAs (circRNAs) are involved in the regulation of gene expression in different physiological and pathological processes. These macromolecules can act as microRNA (miRNA) sponges and play an important role as gene regulators throughout the circRNA-miRNA pathway. In this study, we established a radioresistance model with the nasopharyngeal carcinoma cell line CNE-2, and then analyzed the differences in the circRNAs between radioresistant and normal nasopharyngeal carcinoma cell lines using a high-throughput microarray. Tested circRNAs included 1042 upregulated and 1558 downregulated circRNAs. Relevant signaling pathways associated with the circRNAs and their target miRNAs were analyzed using bioinformatics analysis to determine the radioresistance of the differentially expressed circRNAs. Curcumin was used to treat irradiated cell lines, and changes in the circRNA before and after curcumin treatment were analyzed to investigate the radiosensitization effects of curcumin. The results showed that curcumin could regulate the circRNA-miRNA-messenger RNA network and inhibit the epidermal growth factor receptor (EGFR), signal transducers and activators of transcription 3 (STAT3), and growth factor receptor-bound protein 2 (GRB2) to achieve radiosensitization. Thus, circRNA acted as a miRNA sponge and regulated the expression of miRNA, thereby affecting EGFR, STAT3, and GRB2 expression and radiosensitization.

Abstract
BACKGROUND Nutrition is important for the fetal developmental programming. Nutritional deficiency in early life could increase the susceptibility to many aging-related disorders including cognitive decline. OBJECTIVE Our study aims to investigate the effect of early famine exposure on aging-associated cognitive function. METHODS We recruited 6790 subjects born between 1956 to 1964 during which the Great Chinese Famine occurred (1959-1961). Cognitive function of these subjects were evaluated using the Mini-Mental State Examination (MMSE), the Activities of Daily Living scale (ADL), the Instrumental Activities of Daily Living scale (IADL) and the Clinical Dementia Rating (CDR). RESULTS Our study identified that early exposure to the famine significantly increased the risk of cognitive impairments in later life, leading to higher prevalence of Mild Cognitive Impairment (MCI) and dementia. We also found the sex and rural-urban differences in this malnutrition-induced effect. Illiteracy, history of stroke or diabetes mellitus are great risk factors to facilitate the cognitive decline. CONCLUSION These findings demonstrate that exposure to famine during early life including prenatal period and early childhood facilitates aging-associated cognitive deficits.

Abstract
A majority of Alzheimer's disease (AD) cases are sporadic without known cause. People who suffered from traumatic brain injury (TBI) are more likely to develop neurodegeneration and cognitive impairments. However, the role of TBI in pathophysiology of AD remains elusive. The present study intended to explore the effect of TBI on metabolism and its role in AD pathogenesis. We subjected double transgenic AD model mice APP23/PS45 to TBI. We found that TBI promoted β-secretase cleavage of amyloid β precursor protein and amyloid β protein deposition, and exuberated the cognitive impairments in AD mouse models. 1H nuclear magnetic resonance (1H-NMR)-based metabolomics with multivariate analysis was performed to investigate the characteristic metabolites and the related metabolic pathways in the serum and urine samples of the mice. TBI affected the metabolic patterns, methylamine metabolism, and amino acid metabolism in serum samples. Urinary metabolites showed that glycolysis and the tricarboxylic acid (TCA) cycle were perturbed. The results indicate that TBI might facilitate Alzheimer's pathogenesis by altering metabolism and inducing mitochondrial dysfunction. The study suggests that metabolite changes could also serve as biomarkers for TBI-induced neurodegeneration.

Abstract
OBJECTIVE To explore the attitudes on suicide and their related factors among university students in Chongqing. METHODS A total of 9808 students from 11 universities in Chongqing, were chosen under stratified cluster random sampling method and had completed a questionnaire survey through the Scale of Public Attitudes on Suicide(SPAS). RESULTS Data showed that the scores of university students having negative or neutral attitudes towards questions including "suicide is not preventable", "suicidal behavior is not controllable or is caused by outside forces" and "suicidal behavior can(or is used to)affect the behavior of others'" were 34.28±16.44, 35.64±19.14 and 36.94±16.05 respectively. The scores of students taking neutral attitude towards questions as:"similarity of attempted and completed suicide", "negative attitudes on the behavior or on the person him/her self", "positive aspects of suicide and positive feelings about suicides"were 47.38±22.01, 51.78±17.05 and 37.77±18.12 respectively but 70.77±17.21 went to the students who had agreed with "suicide is an important social/health problem". Factors as gender, nationality, religion, history of attempted suicide and suicide exposure to others appeared having had important effects on the attitude towards suicide among college students. CONCLUSION It is necessary to consider above mentioned factors when developing related suicide crisis intervention strategy.

Abstract
OBJECTIVE To investigate the prevalence of self-reported suicidal behavior in university students and to compare the related risk factors between two selected groups. METHODS A questionnaire survey on situation of suicidal behavior and risk factors was conducted among 9808 university students. RESULTS The overall rate of suicide attempts among university students was 1.7%. Factors as suicidal attitude, having associates who had suicidal experience and negative life events, were significantly different between groups with or without suicide attempts. Risk factors on suicidal behavior were as follows: high frequency of feeling hopeless in the last year (OR = 4.23, 95%CI: 3.05 - 5.85), first degree relatives with suicide behavior (OR = 2.85, 95%CI: 1.72 - 4.73), having associates with suicide behavior (OR = 2.82, 95%CI: 2.05 - 3.88), having had sexual experience (OR = 2.73, 95%CI: 1.88 - 3.96), daily live being influenced by the existing psychological problems in the last month (OR = 2.53, 95%CI: 1.80 - 3.56), being female (OR = 2.47, 95%CI: 1.77 - 3.45) and having other relatives with suicide behaviors (OR = 2.36, 95%CI:1.63 - 3.41). CONCLUSION Psychological, biological and social factors had influenced on suicidal behaviors among university students which all called for effective intervention to be implemented.
