Background: Digital stories have been shown to be effective in sharing information. The Partnerships for Inclusive Research and Learning (PIRL) was a 4-year international participatory research project focussed on the digital divide in inclusive research. Objectives: Members of PIRL share their experience of using digital storytelling to get key messages from the project to a wide range of people. Method: Members of PIRL were invited to develop digital stories and create project-specific guidelines for digital story development. Seven people participated in workshops given by experts, read literature, watched digital stories and discussed how to create digital stories. Results: The group created six digital stories, each one addressing a different aspect related to disability-inclusive research, with many having a focus on Africa and the creation of credible African evidence. The importance of assisting community members to think about and support research and evidence creation was one of the goals of the project. The videos provide an avenue to share insights about disability-inclusive development research. Group members stated that being part of the process significantly improved their understanding of translating evidence into formats that are more understandable. Conclusion: Creating digital stories requires commitment, a significant amount of time, access to digital tools, and financial resources. Working collaboratively on this project was not only meaningful but also encouraged positive working relationships and fostered critical thinking. Contribution: This article contributes to a better understanding of ways in which digital storytelling can be used in knowledge-sharing strategies to promote disability inclusion.

IVIG resistance was associated with an increased risk of coronary artery aneurysm. Accumulating evidences demonstrated that inflammatory gene polymorphisms might play important roles in IVIG resistance, and zinc finger proteins were closely related to immune inflammation regulation, but the effect of ZNF112/rs8113807 and ZNF180/rs2571051 on IVIG resistance in KD patients has not been reported.Methods: A total of 996 KD patients were recruited, and the assay of TaqMan-real-time polymerase chain reaction was used for ZNF112/rs8113807 and ZNF180/rs2571051 genotyping. Odds ratio (OR) and 95% confidence interval (CI) were calculated for estimating the relationship between the polymorphisms of the both SNPs (ZNF112/rs8113807 and ZNF180/rs2571051) and the risk of IVIG resistance.Results: Both of the ZNF112/rs8113807 CC/TC genotype and the ZNF180/rs2571051 TT/CT genotype increased the risk of IVIG resistance in KD (rs8113807: CC vs TT: adjusted OR = 1.83, 95% CI = 1.06– 3.16, p = 0.0293; CC/TC vs TT adjusted: OR = 1.49, 95% CI = 1.10– 2.02, p = 0.0094. rs2571051: TT vs CC adjusted: OR = 2.64, 95% CI = 1.62– 4.29, p < 0.0001; TT/CT vs CC adjusted: OR = 2.14, 95% CI = 1.37– 3.37, p = 0.0009; TT vs CC/CT adjusted: OR = 1.66, 95% CI = 1.22– 2.27, p = 0.0014). Furthermore, the combinative analysis of risk genotypes in ZNF112/rs8113807 and ZNF180/rs2571051 showed that patients with two unfavorable genotypes were more likely to increase risk of IVIG resistance than those who carried with zero or one unfavorable genotypes (adjusted: OR = 1.68, 95% CI = 1.24– 2.27, p = 0.0008).Conclusion: Our findings enriched the genetic background of IVIG resistance risk in the KD development and suggested that the ZNF112/rs8113807 C-carrier and the ZNF180/rs2571051 T-carrier were associated with increased risk of IVIG resistance in KD patients in Chinese southern population.Keywords: Kawasaki disease, ZNF112/rs8113807, ZNF180/rs2571051, IVIG resistance, inflammatory gene, polymorphism

Although studies have shown that the lncRNA CCAT2 is involved in inflammatory diseases, it remains unclear whether CCAT2 gene polymorphisms are associated with susceptibility to inflammatory diseases, such as sepsis, in children.Methods: We genotyped the rs6983267 CCAT2 polymorphism in 474 cases (pediatric sepsis) and 678 controls using TaqMan methods, and odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the strength of associations.Results: Our results indicate that the rs6983267 T > G polymorphism is significantly associated with an increased risk of sepsis in children (TG and TT: adjusted OR = 1.311, 95% CI = 1.016– 1.743, GG and TT: adjusted OR = 1.444, 95% CI = 1.025– 2.034 dominant model: GG/TG vs TT adjusted OR = 1.362, 95% CI = 1.055– 1.756). Furthermore, the risk effect was more pronounced in children younger than 60 months who were male and who had sepsis.Conclusion: We found that the CCAT2 gene polymorphism rs6983267 T > G may be associated with an increased risk of pediatric sepsis in southern China. A larger multicenter study should be performed to confirm these results.Keywords: lncRNA CCAT2, sepsis, susceptibility, polymorphism

Some cardiovascular disease-related candidate genes have been shown to be associated with recurrent miscarriage. Long noncoding RNA ANRIL has been confirmed to be associated with susceptibility to various diseases, such as cardiovascular disease. However, it remains unclear whether the ANRIL gene polymorphism is related to recurrent miscarriage susceptibility.Methods: Three ANRIL gene polymorphisms (rs2151280, rs1063192 and rs564398) were genotyped in 819 controls and 610 recurrent miscarriage patients through TaqMan real-time polymerase chain reaction. The odds ratios and 95% confidence intervals (CIs) were used to assess the strength of each association.Results: Our results showed that the ANRIL rs2151280 GG genotype was associated with increased susceptibility to recurrent miscarriage (GG vs AA: adjusted OR=1.527, 95% CI=1.051– 2.218, p=0.0262; GG vs AG/AA adjusted OR=1.460, 95% CI=1.021– 2.089, p=0.0381). By combining the analysis of the risk genotypes in the three SNPs, we found that individuals with 2– 3 risk genotypes had a significantly increased risk of recurrent miscarriage compared with those with a 0– 1 risk genotype (adjusted OR=1.728, 95% CI=1.112– 2.683, p=0.0149). This risk was more significant in subgroups of women less than 35– 40 years of age and women with 2– 3 miscarriages.Conclusion: These results suggested that a specific SNP in the ANRIL gene may be associated with increased susceptibility to recurrent miscarriage in a southern Chinese population.Keywords: recurrent miscarriage, lncRNA ANRIL, genetic susceptibility, polymorphism

Recently, mutations in the FNDC1 gene have been shown to be associated with inflammatory responses. However, there have been no reports on the relationship between FNDC1 gene and KD so far.Methods: We enrolled 1611 controls and 1459 patients with KD, including 372 patients with coronary artery aneurysm (CAA) and 179 patients with coronary artery lesion (CAL). The relationship between FNDC1 rs3003174 polymorphism and KD with CAA or without CAA was investigated.Results: This study showed no evidence that the association between FNDC1 rs3003174 C>T polymorphism and KD susceptibility was statistically significant (CT versus CC: adjusted odds ratio (OR) =0.897, 95% confidence interval (CI) =0.769– 1.045, P=0.162; TT versus CC: adjusted OR=0.995, 95% CI=0.786– 1.260, P=0.968; dominant model: adjusted OR=0.916, 95% CI=0.792– 1.059, P=0.235; and recessive model: adjusted OR=1.055, 95% CI=0.845– 1.316, P=0.638). However, our further stratified analysis in the control and KD group bore out that the incidence of TT genotype of FNDC1 rs3003174 C > T polymorphism was higher than that of CC/CT genotype in KD patients stratified by CAA (adjusted OR=1.437, 95% CI=1.034– 1.996, P=0.031). Moreover, a stratified analysis of age and gender in KD patients indicated that the rs3003174 TT genotype increased the risk of CAA formation in aged ≦60 months (CC/CT vs TT: adjusted OR=1.580, 95% CI=1.106– 2.259, P=0.012) and male (CC/CT vs TT: adjusted OR=1.653, 95% CI=1.101– 2.481, P=0.015) KD patients.Conclusion: The results of this study demonstrated that the FNDC1 rs3003174 C>T polymorphism may be a hazard factor in the formation of CAA in KD patients that was not disclosed before.Keywords: coronary artery aneurysm, Kawasaki disease, fibronectin type III domain containing 1, polymorphisms

SERPINA4 is involved in inflammation and is associated with susceptibility to a variety of diseases, but its relevance in recurrent miscarriage is unclear. Therefore, this study aimed to investigate the relationship between SERPINA4 gene polymorphisms and susceptibility to recurrent spontaneous abortion.Methods: Two SERPINA4 polymorphisms were genotyped in 631 patients with recurrent miscarriage and 771 controls by TaqMan real-time polymerase chain reaction, and the strength of each association was evaluated through 95% confidence intervals (CIs) and odds ratios (ORs).Results: The results showed that SERPINA4 rs2070777 AA genotypes were associated with an increased risk of recurrent miscarriage (AA vs AT/TT adjusted OR=1.409, 95% CI=1.032– 1.924, P=0.0309), and we also found a significant association between the rs910352 T allele in the SERPINA4 gene and susceptibility to recurrent miscarriage (CT vs CC adjusted OR=1.579, 95% CI=1.252– 1.992, P=0.0001; TT vs CC adjusted OR=1.524, 95% CI=1.134– 2.049, P=0.0052). The combined analysis of two SNPs of the SERPINA4 gene revealed that carriers with one to two unfavorable genotypes were associated with a higher risk for recurrent miscarriage compared with individuals with no unfavorable genotypes (adjusted OR=1.257, 95% CI=1.019-1.550). Moreover, our study indicates that having one to two unfavorable genotypes is associated with an increased risk of recurrent miscarriage in women 35– 40 years of age.Conclusion: Our study suggests that SERPINA4 rs2070777AA genotypes might contribute to an increased risk of recurrent miscarriage in a southern Chinese population.Keywords: recurrent miscarriage, SERPINA4, genetic susceptibility, polymorphism

Previous studies revealed that many genetic variations were related to sepsis susceptibility. A long non-coding RNA SOX2 overlapping transcript (SOX2OT) may play a role in mitochondrial homeostasis and antioxidative activity, but the relationship between the lncRNA SOX2OT polymorphism and sepsis susceptibility has not been reported.Methods: In this study, 474 pediatric sepsis patients and 678 healthy controls were recruited from southern China. After genotyping, the strength of the associations was evaluated through odds ratios (ORs) and 95% confidence intervals (CIs).Results: The SOX2OT rs9839776 T allele was associated with decreased susceptibility to sepsis in southern Chinese children (TT/CT vs CC adjusted OR = 0.778, 95% CI = 0.610– 0.992; P = 0.0431). Moreover, the difference in susceptibility was greater in children of age > 60 months (adjusted OR = 0.458, 95% CI = 0.234– 0.896; P = 0.0225), survivors (adjusted OR = 0.758, 95% CI = 0.585– 0.972; P = 0.0358), males (adjusted OR = 0.655, 95% CI = 0.479– 0.894; P = 0.0077) and the sepsis subgroup (adjusted OR = 0.548, 95% CI = 0.343– 0.876; P = 0.0120).Conclusion: The rs9839776 T allele may contribute to decreased sepsis risk in Chinese children. Future studies with a larger sample size are needed to verify these results.Keywords: sepsis, SOX2OT, rs9839776, susceptibility, polymorphism

This study aimed to examine the effect of COVID-19 measures on 25(OH)D levels in children.Patients and Methods: This study included children who underwent health checks between March 1 and June 30, 2020, and those over the equivalent period during 2017– 2019 (N = 3600). Children’s 25(OH)D levels and the proportion of children with vitamin D deficiency were compared between different observation periods.Results: The mean serum 25(OH)D level was 84 ± 25nmol/L. The overall proportion of children with vitamin D deficiency (25(OH)D level < 50 nmol/L) was 4.6%. Home confinement led to an increase in the proportion of children aged 3– 6 years with vitamin D deficiency during March 1–June 30, 2020 compared with the same months in previous years, and the most noticeable increase was found in March 2020. In children aged 3– 6 years, 25(OH)D levels were lower in 2020 (65 ± 17nmol/L) than during 2017– 2019, and the proportion of those with vitamin D deficiency was higher in 2020 (19.0%) than in previous years. Among children aged 0.5– 1 and 1– 3 years, 25(OH)D levels were higher (97 ± 25 nmol/L, 91 ± 27 nmol/L), while the proportion of children with vitamin D deficiency was lower in 2020 (2.3%, 3.0%) than during 2017– 2019.Conclusion: The 25(OH)D levels tended to decrease gradually with increasing age. Reduced sunlight exposure during confinement is associated with lower 25(OH)D levels among children aged 3– 6 years. Therefore, vitamin D supplementation for children aged > 3 years is recommended.Keywords: 25-hydroxyvitamin D, coronavirus disease, deficiency, sunlight exposure

Interleukin-17 (IL-17), a potent pro-inflammatory cytokine, plays an active role in promoting M2 macrophage differentiation (TAMs are M2-like phenotypes). In this study, we aimed to evaluate that IL-17 stimulates key phenotypic and functional signatures of M2 macrophages associated with cancer progression in non-small-cell lung cancer (NSCLC) patients.Patients and methods: The markers and cytokines of M2 macrophages were detected in THP-1-derived macrophages and mouse peritoneal macrophages treated with IL-17. The activation of nuclear factor kappa B (NF-κB) and nuclear localization of p65 in IL-17-treated cells were investigated. The BAY11-7082 inhibitor and the siRNA of p65 were used to block the NF-κB activation. A total of 85 patients who underwent surgery for histologically verified NSCLC were enrolled in this study. The expression of IL-17 and M2 macrophage markers were assessed by immunostaining. Survivals were estimated using the Kaplan–Meier method.Results: The CD163 and CD206 cell surface markers and transforming growth factor beta (TGF-β), vascular endothelial growth factor (VEGF) and IL-10 of M2 macrophages were significantly increased in IL-17-treated THP-1-derived macrophages in a dose-dependent manner. IL-17 increased the mRNA levels of Arginase I and Fizz1, the phosphorylation of IkBα and nuclear localization of p65 (a subunit of NF-κB). The BAY11-7082 abrogated IL-17-induced CD206 and CD163 expression, TGF-β, VEGF, IL-10, Arginase I and Fizz1 expression and p65 nuclear translocation. Further experiments showed that IL-17 induced the expression of CD206, CD163, Arginase I, Fizz1 and Ym1 in mouse peritoneal macrophages that were inhibited by siRNA of p65. The immunostaining experiments on human NSCLC tissues indicated that high IL-17 expression was significantly correlated with CD163 and c-Maf. The intratumoral IL-17+ CD163+ c-Maf+ cells were associated with NSCLC progression.Conclusion: IL-17 stimulated macrophages to M2-like phenotypes via NF-κB activation. IL-17 may be a potential therapeutic target for NSCLC. Keywords: IL-17, M2 macrophages, NF-κB, non-small-cell lung cancer, survival

This disease generally occurs in children younger than 5 years of age and is more severe in children younger than 12 months. KD affects males and females at a ratio of 1.5:1. Polymorphisms of the rs1625579 locus in the miR-137 gene are associated with schizophrenia susceptibility, and high glucose-induced upregulation of miR-137 in vascular endothelial cells promotes monocyte chemotaxis and inflammatory cytokine secretion in gestational diabetes mellitus. However, researchers have not reported whether rs1625579 is associated with KD susceptibility or onset. Therefore, we investigated the relationship between the miRNA-137 rs1625579 T>G polymorphism and KD susceptibility. Methods: TaqMan real-time polymerase chain reaction was applied to determine the genotypes of 532 patients with KD (365 males and 167 females) and 623 control subjects (402 males and 221 females). Results: Comparison of all cases with all controls revealed that the rs1625579 T>G polymorphism was not associated with KD susceptibility. However, a subgroup analysis revealed that subjects with the rs1625579 TG/GG genotypes exhibited a significantly higher onset risk for KD before 12 months of age than carriers of the TT genotype (adjusted age and gender odds ratio=1.99, 95% CI=1.04–3.83; P=0.039). Conclusion: Our results indicate that the rs1625579 T>G polymorphism confers a risk of early-onset KD in southern Chinese children.

Antiplatelet therapy is a routine component of Kawasaki disease treatment strategies. So it is important to evaluate the antiplatelet effect of aspirin because of the individual biological variability of antiplatelet effect of aspirin. The immature platelet fraction (IPF) has attracted particular attention as it may influence the antiplatelet effect of aspirin. This study investigated the prognostic factors for evaluating the degree of vasculitis and the effect of antiplatelet therapy in children with Kawasaki disease. Materials and methods: Blood samples were collected from 44 patients with Kawasaki disease before aspirin treatment and 7 to 10 days after treatment. The IPF counts, percentage of the IPF, and highly fluorescent IPF were detected by a Sysmex XE-5000 instrument. The levels of 11-dehydrothromboxane B2 (11-DH-TXB2), soluble CD40 ligand (sCD40L), and soluble P-selectin (sP-selectin) were measured by ELISA. The correlation between the measured factors and the degree of coronary artery damage in Kawasaki disease was analyzed. Results: We found that 11-DH-TXB2, sP-selectin, and sCD40L levels were much more elevated in the CAL group than in the non-coronary artery lesions (NCAL) group before aspirin treatment. The concentrations of 11-DH-TXB2, sCD40L, sP-selectin, and IPF were reduced after aspirin treatment in the NCAL group but not the CAL group. This is related to the degree of coronary artery damage in Kawasaki disease patients. Additionally, 11-DH-TXB2, sCD40L, sP-selectin, and IPF were positively correlated with the degree of coronary artery damage in Kawasaki disease patients. Conclusion: The current study suggests that the presence of high plasma concentrations of 11-DH-TXB2, sCD40L, sP-selectin, and IPF can be considered a risk factor and experimental biomarker for CAL in Kawasaki disease patients.

Youwen Zhang, Deyin Tong, Daobiao Che, Bing Pei, Xiaodong Xia, Gaofeng Yuan, Xin Jin Department of Hospital Pharmacy, The First Hospital of Suqian, Suqian, People’s Republic of China Abstract: The roles of ginsenoside compound K (CK) in inhibiting tumor have been widely recognized in recent years. However, low water solubility and significant P-gp efflux have restricted its application. In this study, CK ascorbyl palmitate (AP)/d-α-tocopheryl polyethylene glycol 1000 succinate monoester (TPGS) mixed micelles were prepared as a delivery system to increase the absorption and targeted antitumor effect of CK. Consequently, the solubility of CK increased from 35.2±4.3 to 1,463.2±153.3 µg/mL. Furthermore, in an in vitro A549 cell model, CK AP/TPGS mixed micelles significantly inhibited cell growth, induced G0/G1 phase cell cycle arrest, induced cell apoptosis, and inhibited cell migration compared to free CK, all indicating that the developed micellar delivery system could increase the antitumor effect of CK in vitro. Both in vitro cellular fluorescence uptake and in vivo near-infrared imaging studies indicated that AP/TPGS mixed micelles can promote cellular uptake and enhance tumor targeting. Moreover, studies in the A549 lung cancer xenograft mouse model showed that CK AP/TPGS mixed micelles are an efficient tumor-targeted drug delivery system with an effective antitumor effect. Western blot analysis further confirmed that the marked antitumor effect in vivo could likely be due to apoptosis promotion and P-gp efflux inhibition. Therefore, these findings suggest that the AP/TPGS mixed micellar delivery system could be an efficient delivery strategy for enhanced tumor targeting and antitumor effects.

Reef restoration has gained attention as it has strategic actions and powerful means in sustaining and maintaining coastal ecosystem services. This scientometric study systematically analyzes the current trends and research hotspot in coral restoration across the last five decades (1971–2022). The metadata (12,667 articles with 652,860 cited references) were obtained from the Clarivate Web of Science platform through the Core Collection database, associated with the CiteSpace and R‐software for further analysis. The results indicated that the trend of coral restoration is increasing in paper/year, with the United States, Australia, and China as major contributors to the related research. Furthermore, James Cook University, Australia had the largest number of articles, and the Consortium of Research Libraries of the United Kingdom was the most influential institution on coral restoration. The highly cited keywords are "Great Barrier Reef," "climate change," and "coral reef," while the most influential keywords are "coral," "model," and "Atlantic." A total of 23 clusters in the field with "coral reef," "phase shift," "bacterial communities," "coral restoration," "symbiotic dinoflagellate," "stony coral tissue loss disease," "bleaching event," "ocean acidification," "oyster reef," and "quantitative reconstruction" are among the top cluster size labeled. Early‐stage researcher may use both keywords and cluster analysis to find topics attractive to their future research projects. In addition, this study contributes toward evaluating recent scientific productivity about coral restoration as well as informing researchers and policymakers regarding funding, future strategic planning, and potential collaboration opportunities.
