Abstract
BACKGROUND In the context of the global aging challenge, an increasing number of middle-aged and older adults (MAOAs) are engaging in grandparenting. However, the effect of grandparenting on the mental health of caregivers has shown inconsistent findings. To effectively promote healthy aging, it is imperative to adopt a comprehensive perspective and employ a rigorous approach to further investigate the relationship between these two social phenomena. METHODS The data from the Harmonized China Health and Retirement Longitudinal Study were analyzed, focusing on MAOAs with at least one grandchild. Mental health assessments used the center for epidemiologic studies depression scale scale. The study employed a series of difference-in-differences (DID) models, especially complemented by propensity score matching, to evaluate the average treatment effect for the treated (ATT) on mental health of caregivers, considering covariates like personal and family characteristics. The intervention perspective includes both the provision and cessation of grandparenting. RESULTS The study found that providing grandchildren care does not have a significant effect on the mental health of grandparents, in comparison to those who have never engaged in such care (ATT = -0.172, T = 0.65, p = 0.517 in the PSM-DID model). Furthermore, ceasing this care also appears to have no substantial effect on the mental health of the caregivers, relative to individuals who have consistently offered grandchildren care (ATT = 0.060, T = 0.26, p = 0.795 in the PSM-DID model). Furthermore, subsequent robustness analyses consistently supported these findings, even when considering data from different survey waves. CONCLUSIONS In contrast to many prior studies that have reported either positive or negative effects, our research reveals that grandparenting exerts no significant effect on the mental health of MAOAs. Consequently, health practitioners and policymakers should carefully consider the diverse cultural context when tailoring interventions and support strategies.

Abstract
OBJECTIVE To investigate the superiority of preoperative ultrasound-guided titanium clip and nanocarbon dual localization over traditional methods for determining the surgical approach and guiding resection of Siewert type II adenocarcinoma of the esophagogastric junction (AEG). METHOD This study included 66 patients with Siewert type II AEG who were treated at the PLA Joint Logistics Support Force 900th Hospital between September 1, 2021, and September 1, 2023. They were randomly divided into an experimental group (n = 33), in which resection was guided by the dual localization technique, and the routine group (n = 33), in which the localization technique was not used. Surgical approach predictions, proximal esophageal resection lengths, pathological features, and the occurrence of complications were compared between the groups. RESULT The use of the dual localization technique resulted in higher accuracy in predicting the surgical approach (96.8% vs. 75.9%, P = 0.02) and shorter proximal esophageal resection lengths (2.39 ± 0.28 cm vs. 2.86 ± 0.39 cm, P < 0.001) in the experimental group as compared to the routine group, while there was no significant difference in the incidence of postoperative complications (22.59% vs. 24.14%, P = 0.88). CONCLUSION Preoperative dual localization with titanium clips and carbon nanoparticles is significantly superior to traditional methods and can reliably delineate the actual infiltration boundaries of Siewert type II AEG, guide the surgical approach, and avoid excessive esophageal resection.

Abstract
BACKGROUND The culturally sensitive nursing practice has not embedded filial piety as a cultural value and stance pertaining to caregiving among aging Chinese and Chinese-American (CCA) families in the United States, yet it is critical for healthy aging among CCAs. PURPOSE To understand filial piety when caring for aging CCAs and conceptualize an operational definition and framework. METHODS A systematic search was conducted in CINAHL, PubMed, Scopus, and PsycINFO databases. Analysis of the concept of filial piety among CCAs used Walker and Avant's methods. Twenty-six studies were selected in the final full-text analysis. FINDINGS Synthesis of evidence identified four antecedents: (a) filial obligation as a 'cultural gene', (b) sense of altruism, (c) familial solidarity, and (d) societal expectation of 'birth right'. Attributes included familial material and emotional support, obedience, pious reverence, and societal norms. Consequences were related to caregiver burden, psychological and physical well-being, quality of life, and health equity. CONCLUSION Filial piety is an intrinsic desire to support aging parents and an extrinsic desire to adhere to Chinese societal moral tenets. The proposed operational framework "Caregiving for aging CCAs in the United States" merits further study.

Abstract
Recent growing evidence suggests a role for intestinal microbiome and metabolites in patients' postoperative recovery. Therefore, there is a need to gain insight into the impact of pancreaticoduodenectomy for periampullary carcinoma on microbiome and metabolites and the potential impact of their changes on patients' condition. Based on 16S rDNA gene sequencing and untargeted metabolomic analysis, we found that the diversity and abundance of intestinal microbiome were significantly higher in patients preoperatively than postoperatively, and the level of intestinal probiotics was significantly lower after surgery compared with preoperatively. In addition, the choline metabolism level was increased and the amino acid metabolism level was decreased after surgery. A total of 53 differential microbiome and 52 differential metabolites were detected, and the differential metabolites were mapped to approximately 60 different KEGG metabolic pathways, of which 13 KEGG metabolic pathways had a differential metabolite number greater than 5. A total of 88 colony-metabolite pairs with significant positive correlation and 69 colony-metabolite pairs with significant negative correlation were identified. Our results reveal alterations in intestinal microbiome after pancreaticoduodenectomy, suggesting its association with postoperative complications. Moreover, the elevated choline metabolism level in postoperative patients may predict their poorer prognosis. At the same time, the decreased abundance of such probiotic bacteria as Prevotella spp. in the postoperative intestine of patients will affect the amino acid metabolism of the organism to some extent.

Abstract
BACKGROUND People with chronic obstructive pulmonary disease (COPD) occasionally develop acute exacerbation of COPD-a potentially fatal condition. Psychological distress was associated with acute exacerbation of COPD. However, the evidence on the effect of psychological distress on acute exacerbation of COPD remains unclear. OBJECTIVE The aim of this study was to explore the influence of psychological distress on acute exacerbation of COPD and its consequences. METHODS The current review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using three databases (PubMed, CINAHL, and PsyINFO) that were searched to identify relevant articles. Pooled risk ratios and 95% confidential interval were calculated from the included studies' data with random-effect methods to estimate the effect of psychological distress on acute exacerbation of COPD and its consequences. RESULTS Nineteen articles were included in the review. Most revealed that psychological distress was significantly associated with increased risk of acute exacerbation of COPD and its consequences. The meta-analyses showed that psychological distress increased risk of acute exacerbation of COPD, COPD-related hospitalization, and death. CONCLUSION Psychological distress had negative effects on acute exacerbation of COPD and its consequences. The results of the meta-analyses show that persons with COPD and psychological distress had a greater risk of acute exacerbation of COPD, hospitalization, and death.

Abstract
BACKGROUND/AIM Endometrial cancer (EC) is a frequent gynecological cancer. Studies have demonstrated that the sensitivity of EC toward 5-fluorouracil (5-FU) chemotherapy has decreased, leading to unsatisfactory treatment effects. There is an urgent need to investigate the reasons for the unsatisfactory treatment of EC with 5-FU. The purpose of the study was to investigate the effect of RAD51AP1 after being transcriptionally activated by E2F7 on the sensitivity of EC cells to 5-FU chemotherapy via the fatty acid metabolic pathway. MATERIALS AND METHODS mRNA expression data on EC were downloaded from The Cancer Genome Atlas database, subjected to differential expression analysis, and the target genes were determined based on the bioinformatics analysis and literature consulting. The regulatory transcription factor upstream of RAD51AP1 in EC was predicted using the hTFtarget database. The expression of E2F7 and RAD51AP1 was measured by qRT-PCR and western blot. Then, the transcriptional activation relationship between E2F7 and RAD51AP1 was verified by chromatin immunoprecipitation (ChIP) and dual luciferase assays. The IC50 values of EC cells toward 5-FU were determined by the CCK-8 assay, and cell apoptosis was detected by flow cytometry. The expression of apoptosis-related and fatty acid metabolism-related proteins was evaluated by western blot. RESULTS Bioinformatics analysis showed that both E2F7 and RAD51AP1 were highly expressed in EC, and the possible binding sites between RAD51AP1 promoter and E2F7 were predicted. ChIP assay and dual luciferase assay confirmed the binding of E2F7 to RAD51AP1 promoter region. Cell experiments showed that overexpressing RAD51AP1 could facilitate the growth and fatty acid metabolism of EC cells, and suppress cell sensitivity to 5-FU, while silencing of E2F7 could reduce the effect of RAD51AP1 overexpression on EC cell growth and sensitivity toward 5-FU. CONCLUSION The E2F7/RAD51AP1 axis can promote the growth of EC cells and inhibit cell sensitivity to 5-FU by regulating fatty acid metabolism, suggesting that E2F7/RAD51AP1 axis may be a novel pathway for EC treatment.

Abstract
Thermal management, including heating and cooling, plays an important role in human productive activities and daily life. Nevertheless, in the actual environment, almost all the ambient scenarios come with the challenge that the objects are located in a quite dynamic and variable environment, which includes fluctuations in aspects such as space, time, sunlight, season, and temperature. It is imperative to develop low-energy or even zero-energy thermal-management technologies with renewable and clean energy. In this review, we summarised the latest technological advances and the prospects in this burgeoning field. First, we present the fundamental principles of the daytime passive radiative cooling (PDRC) thermal management device. Next, In the domain of dual-mode systems, they are classified into various types based on the diverse mechanisms of transitioning between cooling and heating states, including electrical responsive, mechanical responsive, temperature responsive, and solution responsive. Furthermore, we conducted an in-depth analysis of the principles and design methodologies associated with these categories, followed by a comparative assessment of their performance in radiative cooling and solar heating applications. Finally, this review presents the challenges and opportunities of dynamic dual mode thermal management, while also identifying future directions.

Abstract
PURPOSE/OBJECTIVE(S) Immunotherapy combined with radiotherapy (iRT) has unlimited potential, but up to 60% of cancer patients do not benefit from it. Enhancing the anti-tumor immune stimulatory effect triggered by radiotherapy is the key to overcome iRT resistance. Immunoglobulin-like transcript (ILT) 4 is a potential immune checkpoint molecule, highly expressed in various tumor cells, but its role in radiotherapy is still unknown. This study confirmed the role and molecular mechanism of ILT4 in suppressing radiotherapy immunosuppressive microenvironment formation and promoting tumor radiotherapy resistance. We propose a new therapeutic strategy that block ILT4 to enhance the efficacy of radiotherapy, and cooperate with radiotherapy to reverse immunotherapy resistance. MATERIALS/METHODS Using multiplex immunohistochemistry, we analyzed ILT4 expression, tumor-associated macrophage (TAM) /T cell phenotype and quantity in tumor patient treated with SBRT. Using mice subcutaneous tumor models, Single-cell RNA sequencing and multiplex flowcytometry, we assessed the role of ILT4 inhibition and hyper-fractionated radiotherapy (HFRT) on preventing tumor growth and immune escape. The molecular signaling and cytokines regulated by ILT4 under HFRT were analyzed by transcriptome sequencing and further verified by molecular experiments. By establishing cancer cell/TAM co-culture system in vitro, using CXCL1 protein or CXCR2 inhibitor and macrophage/CD8+ T cell deletion antibody in vivo, we identified the downstream pathway and cytokine of ILT4 to enhancing HFRT -induced TAM immune response. RESULTS In the tumor specimens of NSCLC patients treated with SBRT, we found that high ILT4 expression predicted poor progression-free survival and more M2-TAM recruitment. Among the C57BL/6 mice model, ILT4 inhibition in cancer cells reduced HFRT mediated M2-TAMs accumulation, and to sustain activation and proliferation of CD8+ T cells, and eventually suppressed tumor progression. Mechanistically, RT promoted ILT4 expression, which subsequently induced NF-κB pathway activation and CXCL1 secretion to enhance M2-TAMs migration in vitro. Using CXCL1 protein or CXCR2 inhibitor administration, inferring that ILT4 promotes TAMs migration via NF-κB-CXCL1-CXCR2 axis. Consistently, depletion of TAMs blocked the T cell function impairment and radiotherapy resistance induced by ILT4 in vivo. Importantly, targeting ILT4 potentiated the effect of radiotherapy, overcomes radio-immunotherapy treatment resistance. CONCLUSION ILT4 mediates HFRT-induced M2-like TAMs recruitment and subsequently T cell response impairment by regulating NF-κB-CXCL1-CXCR2 axis. ILT4 is an attractive drug target for enhancing radiotherapy and overcomes radio-immunotherapy treatment resistance.

Abstract
PURPOSE/OBJECTIVE(S) Radioimmunotherapy for non-small cell lung cancer has good clinical application prospects. The role and mechanism of RUNX1 in DNA damage repair were explored for its potential role in lung adenocarcinoma radioimmunotherapy. MATERIALS/METHODS To study the effect of RUNX1 expression level on the expression of DNA damage repair system related factors and radiation sensitivity of lung adenocarcinoma cells. As an important nuclear transcription factor, RUNX1 was explored whether directly regulating the expression of Nrf2, Rad51, BRCA1, and verifying their respective DNA binding sites in the promoter region through relevant databases. To observe the effect of RUNX1 knockout and overexpression on the expression level of PD-L1 in tumor cells at the cell level; The effect of RUNX1 expression level on the sorting and presentation of PD-L1 cells was investigated by the method of nucleocytoplasmic separation. According to literature reports, CMTM6 and ALIX play a key role in the process of PD-L1 cell sorting and presentation, and explore whether RUNX1 plays a role through this factor. The effect of phosphorylation level of different splicing bodies of RUNX1 (RUNX1a/b/c) on the expression level and DNA damage repair system related factors on tumor radiosensitivity were also explored. RESULTS According to TCGA database, RUNX1 is highly expressed and phosphorylated in lung adenocarcinoma. Through gene comparison with the database, it was found that RUNX1 binding sites existed in the promoter region of several factors related to this study, including ALIX, Nrf2, BRCA1, RAD51, ATM, H2AX, etc. After being activated by MAPKp38 phosphorylation, RUNX1a can positively regulate Nrf2 signal pathway. The expression of RUNX1 and p-RUNX1 is time-dependent on ionizing radiation. At the same time, it was found that the expression of RUNX1 and p-RUNX1 was dose-dependent on ionizing radiation, and the expression trend of Nrf2 signal pathway related factors was consistent with RUNX1. RUNX1 regulates the expression of PD-L1, BRCA1, ALIX and Nrf2. Bioinformatics analysis and flow cytometry data show that RUNX1 has inhibitory effect on tumor microenvironment of lung adenocarcinoma. CONCLUSION RUNX1 regulates DNA damage repair system and has inhibitory effect on tumor immunity. Inhibiting the expression of RUNX1 in lung adenocarcinoma cells can enhance the effect of radioimmunotherapy.

Abstract
OBJECTIVE To investigate whether gut microbiota disturbance after cardiopulmonary bypass (CPB) contributes to the development of perioperative neurocognitive disorders (PND). METHODS Fecal samples were collected from healthy individuals and patients with PND after CPB to prepare suspensions of fecal bacteria, which were transplanted into the colorectum of two groups of pseudo-germ-free adult male SD rats (group NP and group P, respectively), with the rats without transplantation as the control group (n=10). The feces of the rats were collected for macrogenomic sequencing analysis, and serum levels of IL-1β, IL-6 and TNF-α were measured with ELISA. The expression levels of GFAP and p-Tau protein in the hippocampus of the rats were detected using Western blotting, and the cognitive function changes of the rats were assessed with Morris water maze test. RESULTS In all the 3 groups, macrogenomic sequencing analysis showed clustering and clear partitions of the gut microbiota after the transplantation. The relative abundances of Klebsiella in the control group (P < 0.005), Akkermansia in group P (P < 0.005) and Bacteroides in group NP (P < 0.005) were significantly increased after the transplantation. Compared with those in the control group, the rats in group NP and group P showed significantly decreased serum levels of IL-1β, IL-6 and TNF-α and lowered expression levels of GFAP and p-Tau proteins (all P < 0.05). Escape platform crossings and swimming duration in the interest quadrant increased significantly in group NP (P < 0.05), but the increase was not statistically significant in group N. Compared with those in group P, the rats in group NP had significantly lower serum levels of IL-1β, IL-6 and TNF-α and protein expressions of GFAP and p-Tau (all P < 0.05) with better performance in water maze test (P < 0.05). CONCLUSION In patients receiving CPB, disturbances in gut mirobiota contributes to the development of PND possibly in relation with inflammatory response.

Abstract
BACKGROUND Vascular endothelial growth factor receptor 2 (VEGFR2) plays a key role in antiangiogenesis which has been an essential strategy for cancer treatment. We report the first-in-human study of AK109, a novel anti-VEGFR2 monoclonal antibody, to characterize the safety profile and pharmacokinetics/pharmacodynamics (PK/PD) properties, and explore the preliminary antitumor efficacy in patients with solid tumors. PATIENTS AND METHODS This was a multicenter, open-label, phase I study, including dose escalation and dose expansion (NCT04547205). Patients with advanced cancers were treated 2 and 3 weekly with escalating doses of AK109. A 3 + 3 design was used to determine the maximum tolerated dose. Blood was sampled for PK/PD analysis. The primary endpoint was safety and recommended phase II dose (RP2D). RESULTS A total of 40 patients were enrolled. No dose-limiting toxicity was observed. However, 38 patients reported treatment-related adverse events (TRAEs); grade ≥3 TRAEs occurred in 10 patients. The most common TRAEs were proteinuria (n = 24, 60%), hypertension (n = 13, 32.5%), increased aspartate transaminase (n = 11, 27.5%), thrombopenia (n = 10, 25%), and anemia (n = 10, 25%). A total of 28 patients (70%) reported adverse events of special interest (AESIs). The most common AESIs were proteinuria (60%), hypertension (32.5%), and hemorrhage (32.5%), mainly including gum bleeding and urethrorrhagia. AK109 exhibited an approximately linear PK exposure with dose escalation at 2-12 mg/kg. PD analyses showed rapid target engagement. Among the 40 patients, 4 achieved partial response and 21 achieved stable disease with an objective response rate of 10% and a disease control rate of 62.5%. Based on the safety profile, the PK/PD profile, and preliminary antitumor activities, 12 mg/kg Q2W and 15 mg/kg Q3W were selected as RP2D. CONCLUSIONS AK109 showed manageable safety profile and promising antitumor activity, supporting further clinical development in a large population.

Abstract
OBJECTIVE We primarily aimed to investigate whether there are phenotypic and genetic links underlying body mass index (BMI) and overall osteoarthritis (OA). We then intended to explore whether the relationships differ across sexes and sites. METHOD We first evaluated the phenotypic association between BMI and overall OA using data from the UK Biobank. We then investigated the genetic relationship leveraging summary statistics of the hitherto largest genome-wide association studies performed for BMI and overall OA. Finally, we repeated all analyses in a sex- (female, male) and site- (knee, hip, spine) specific manner. RESULTS Observational analysis suggested an increased hazard of diagnosed OA per 5 kg/m2 increment in BMI (hazard ratio = 1.38, 95% confidence interval (CI) = 1.37-1.39). A positive overall genetic correlation was observed for BMI and OA (rg = 0.43, P = 4.72 × 10-133), corroborated by 11 significant local signals. Cross-trait meta-analysis identified 34 pleiotropic loci shared between BMI and OA, of which seven were novel. Transcriptome-wide association study revealed 29 shared gene-tissue pairs, targeting nervous, digestive, and exo/endocrine systems. Mendelian randomization demonstrated a robust BMI-OA causal relationship (odds ratio = 1.47, 95% CI = 1.42-1.52). A similar pattern of effects was observed in sex- and site-specific analyses, with BMI affecting OA comparably in both sexes and most strongly in the knee. CONCLUSION Our work demonstrates an intrinsic relationship underlying BMI and overall OA, reflected by a pronounced phenotypic association, significant biological pleiotropy, and a putative causal link. Stratified analysis further reveals that the effects are distinct across sites and comparable across sexes.

Abstract
Multiple mental diseases could arise in people who have the disrupted in schizophrenia 1 (DISC1) gene. However, it was unknown how DISC1 might contribute to the development of tumors and immune responses. We extracted data from the Cancer Genome Atlas (TCGA) and TISIDB databases from stomach adenocarcinoma (STAD) patients, which revealed that DISC1 overexpression was closely associated with tumor histological type (mucinous vs. tubular, OR = 2.860, CI = 1.423-5.872, p = 0.004), as well as tumor stage and grade. Furthermore, the higher the DISC1 expression, the lower the overall 10-year survival rate. Patients with low DISC1 expression had a significantly longer progression-free interval (PFI) and disease-specific survival (DSS) than patients with high DISC1 expression. However, patients with higher DISC1 expression in the T3&T4, N0&N1 and M0 subgroups had poorer prognosis in terms of OS, DSS and PFI, as could be seen in the subgroup survival analysis. Public datasets were used to predict lncRNA-miRNA-DISC1 regulation. DISC1 was significantly up-regulated in GC(gastric cancer), and its expression levels showed a moderate to strong positive correlation with infiltration levels of effector memory T cells (Tem) and central memory T cells (Tcm), and a negative correlation was observed with Th17 cells and NK CD56bright cells. In addition, concomitant with the high expression of the DISC1 gene was a decrease in MHC-I (Major Histocompatibility Complex-I)expression and an increase in MHC-II expression, and altered chemokine expression. The upregulation of CXCL12 and CXCR4 expression could be caused by an increase in DISC1 expression. The above expression variability and correlation suggest a role for DISC1 in regulating tumor immunity in GC. These findings suggest that high expression of DISC1 could be an independent prognostic factor for GC.

Abstract
Family caregivers struggle with multi-dimensional demands in caring for persons living with dementia (PLWD). The challenges of caregiving combined with the requirements of daily life can impact the care of PLWD and the health and well-being of the caregivers. The purpose of this study was to describe caregivers’ perceptions of the worst part of their day in the context of daily caregiving challenges. Family caregivers completed online surveys reporting on various parts of their day. The survey included an optional open-ended question: “what was the worst part of your day?” Caregivers (N=165) completed diaries for 21 days resulting in 1,773 surveys that included a response to the optional open-ended question. A subset of data was analyzed using content analysis to identify initial codes and themes; further content analysis of the complete dataset was used to confirm and refine the identified codes and themes. Final analysis revealed 6 themes describing caregivers’ perceptions of the worst part of their day. These themes included days in which they had to: 1) cope with changes in their relationship with the PLWD, 2) manage their own health-related issues such as illness and lack of sleep, 3) struggle when there was a lack of help or support, 4) deal with daily life demands in the home along with the demands of caregiving, 5) cope with negative emotions such as sadness, grief, or anger over the disease process, 6) cope with physical exhaustion. The findings reflect daily stressors associated with caregiving for PLWD.

Abstract
Objective: To analyze the influencing factors of iron metabolism assessment in patients with myelodysplastic syndrome. Methods: MRI and/or DECT were used to detect liver and cardiac iron content in 181 patients with MDS, among whom, 41 received regular iron chelation therapy during two examinations. The adjusted ferritin (ASF) , erythropoietin (EPO) , cardiac function, liver transaminase, hepatitis antibody, and peripheral blood T cell polarization were detected and the results of myelofibrosis, splenomegaly, and cyclosporine were collected and comparative analyzed in patients. Results: We observed a positive correlation between liver iron concentration and ASF both in the MRI group and DECT groups (r=0.512 and 0.606, respectively, P<0.001) , only a weak correlation between the heart iron concentration and ASF in the MRI group (r=0.303, P<0.001) , and no significant correlation between cardiac iron concentration and ASF in the DECT group (r=0.231, P=0.053) . Moreover, transfusion dependence in liver and cardiac [MRI group was significantly associated with the concentration of iron in: LIC: (28.370±10.706) mg/g vs (7.593±3.508) mg/g, t=24.30, P<0.001; MIC: 1.81 vs 0.95, z=2.625, P<0.05; DECT group: liver VIC: (4.269±1.258) g/L vs (1.078±0.383) g/L, t=23.14, P<0.001: cardiac VIC: 1.69 vs 0.68, z=3.142, P<0.05]. The concentration of EPO in the severe iron overload group was significantly higher than that in the mild to moderate iron overload group and normal group (P<0.001) . Compared to the low-risk MDS group, the liver iron concentration in patients with MDS with cyclic sideroblasts (MDS-RS) was significantly elevated [DECT group: 3.80 (1.97, 5.51) g/L vs 1.66 (0.67, 2.94) g/L, P=0.004; MRI group: 13.7 (8.1,29.1) mg/g vs 11.6 (7.1,21.1) mg/g, P=0.032]. Factors including age, bone marrow fibrosis, splenomegaly, T cell polarization, use of cyclosporine A, liver aminotransferase, and hepatitis antibody positive had no obvious effect on iron metabolism. Conclusion: There was a positive correlation between liver iron concentration and ASF in patients with MDS, whereas there was no significant correlation between cardiac iron concentration and ASF. Iron metabolism was affected by transfusion dependence, EPO concentration, and RS.

Abstract
Lipid metabolism is an important biochemical process in the body. Recent studies have found that environmental endocrine disruptors play an important role in the regulation of lipid metabolism. Bisphenol A (BPA), a common environmental endocrine disruptor, has adverse effects on lipid metabolism, but the mechanism is still unclear. This study aimed to investigate the effects of gestational BPA exposure on hepatic lipid metabolism and its possible mechanism in male offspring. The pregnant Sprague-Dawley rats were exposed to BPA (0, 0.05, 0.5, 5 mg/kg/day) from day 5 to day 19 of gestation to investigate the levels of triglyceride (TG) and total cholesterol (TC), and the expression of liver lipid metabolism-related genes in male offspring rats. The results showed that compared with the control group, the TG and TC levels in serum and liver in BPA-exposed groups was increased. And the expressions of liver fatty acid oxidation related genes, such as peroxisome proliferators-activated receptor α (PPARα) and carnitine palmitoyl transferase 1α (CPT1α), were down-regulated. However, the expressions of fatty acid synthesis related genes, such as sterol regulatory element binding proteins 1 (SREBP-1), acetyl-CoA carboxylase 1 (ACC1), fatty acid synthase (FAS) and stearoyl-CoA desaturase 1 (SCD-1), were up-regulated. The increased protein levels of mTOR and p-CRTC2 suggested that CREB-regulated transcription coactivator 2 (CRTC2) might be an important mediator in the mTOR/SREBP-1 pathway. In conclusion, these results demonstrated that mTOR/CRTC2/SREBP-1 could be affected by gestational BPA exposure, which may involve in the lipid metabolic disorders in later life.

Abstract
Background Preoperative serum gamma-glutamyl transferase (γ-GT) levels is significantly related to the prognosis of hepatocellular carcinoma (HCC), but its clinical value in the management of postoperative adjuvant transarterial chemoembolization (PA-TACE) has rarely been explored. This study aimed to investigate whether γ-GT levels could be taken as a biomarker to guide the management of PA-TACE in resectable HCC. Methods HCC patients receiving radical resection were identified through the primary liver cancer big data (PLCBD) from December 2012 to December 2015. Prognostic factors of overall survival (OS) and disease-free survival (DFS) were identified by univariate and multivariate cox analyses, and subgroup analysis was conducted between PA-TACE group and non-TACE stratified by γ-GT levels before and after 1:1 propensity score matching (PSM). Results γ-GT level was found to be an independent risk factor of OS and DFS in 1847 HCC patients receiving radical resection (both P < 0.05), and patients with elevated γ-GT(> 54.0 U/L) have a shortened median OS and DFS, compared with those with normal γ-GT (both P < 0.001). In the subgroup of patients with normal γ-GT, there were no significant differences between groups of PA-TACE and non-TACE in terms of median OS and DFS before and after PSM (all P > 0.05), and PA-TACE was not a significant prognostic factor of both OS and DFS before and after PSM (all P > 0.05). In the subgroup of patients with elevated γ-GT, significant differences were found between groups of PA-TACE and non-TACE in terms of median OS and DFS before and after PSM (all P < 0.05), and PA-TACE was an independent prognostic factor of both OS and DFS (all P < 0.05). Conclusion Currently, we concluded that patients with more advanced HCC also have more elevated γ-GT, and these patients with elevated γ-GT would be benefited more from PA-TACE after radical resection.

Abstract
BACKGROUND In 2017, the World Health Organization redefined two different forms of tumor components containing both neuroendocrine and non neuroendocrine as mixed neuroendocrine-non-neuroendocrine tumor (MiNEN). It occurs in different parts of the body, including the urogenital tract,the upper respiratory tract, the digestive tract. It has a very poor prognosis. CASE PRESENTATION A 61 year old man was admitted to hospital with incidental pancreatitis. CT examination showed that the injury of duodenal branch resulted in hematoma formation. Pancreatic space occupying lesions were found by surgical exploration,so he underwent radical pancreatoduodenectomy, right hemicolectomy and jejunostomy. A pathological examination revealed that the tumor was composed of large cell neuroendocrine carcinoma, ductal adenocarcinoma and undifferentiated sarcoma. The tumor invaded the stomach, duodenum and colon. Half a month after the operation, the patient died of leukocytic reaction. CONCLUSIONS At present, MiNEN is rare with Triphasic Histological Pattern. The diagnosis and treatment of MiNEN are challenging.

Abstract
BACKGROUND AND AIMS Surgical resection for patients with intermediate hepatocellular carcinoma (HCC) is preferred in China, but the prognosis remains far from satisfactory. Postoperative transarterial chemoembolization (p-TACE) has been conducted prevalently to prevent recurrence, but its efficacy remains controversial. Hence, we collected the data from primary liver cancer big data (PLCBD) to investigate the clinical value of p-TACE for patients with intermediate HCC and identify the potential beneficiaries. METHODS Patients who were diagnosed with intermediate HCC between December 2012 and December 2015 were identified through the PLCBD. Disease-free survival (DFS) of patients who received p-TACE or not following radical resection was evaluated using Kaplan-Meier survival curves before and after 1:1 propensity scoring match (PSM). Subgroup analysis was conducted stratified by risk factors associated with recurrence. RESULTS A total of 325 intermediate HCC patients receiving radical resection were eligible in this study, including 123 patients in the p-TACE group and 202 in the non-TACE group. Median DFS in the p-TACE group was significantly longer than in the non-TACE group (23.3 months vs. 18.0 months, P = 0.016) in the whole cohort with no severe complicates, which was confirmed in a well-matched cohort (17.4 months vs. 23.3 months, P = 0.012). In addition, p-TACE was identified as an independent risk factors of DFS by multivariate Cox regression analysis before and after PSM (both P < 0.05). After adjusting for other prognostic variables, patients were found to significantly benefit from p-TACE in DFS if they were male, or had hepatitis, diabetes, cirrhosis, AFP ≤ 400 ng/ml, anatomic hepatectomy, no severe surgical complication, no intraoperative transfusion, tumor number = 2, differentiation grading III, capsule, or had no transfusion (all P < 0.05). CONCLUSION With the current data, we concluded that p-TACE was safe and efficient for the patients with intermediate HCC following radical resection, and male patients with hepatitis, diabetes, cirrhosis, AFP ≤ 400 ng/ml, anatomic hepatectomy, no severe surgical complication, no intraoperative transfusion, tumor number = 2, differentiation grading III, and capsule would benefit more from p-TACE.

Abstract
Abstract Objective To construct a polymerase chain reaction-capillary electrophoresis (PCR-CE) detection method using ChlB gene and NIES gene, investigate the method's specificity and sensitivity, and to evaluate its application value in drowning diagnosis. Methods The specific primers ChlB and NIES were designed for the conserved sequence of chlorophyte ChlB gene and cyanophyte NIES gene in GenBank to construct PCR-CE detection method; 50 species of standard DNA samples were amplified; the sensitivity was determined by gradient concentration detection of positive standard samples; 25 actual cadaver lung tissue samples (drowned: 20, natural death: 5) were detected, and the simultaneous detection results of microwave digestion-vacuum filtration-automated scanning electron microscopy (MD-VF-Auto SEM) were simultaneously compared. Results The minimum DNA detection concentration of primers ChlB and NIES was 0.161 ng and 0.109 ng, respectively, which could specifically amplify chlorophyte (Chlorella pyrenoidosa) and cyanophyte [Microcystis aeruginosa (producing and not producing toxin)] widespread in water. The product fragments were 156 bp and 182 bp, respectively. The results of non-drowning tissues were negative. Conclusion This method has high sensitivity and specificity. It can be applied to the detection of plankton related to drowning and combined with MD-VF-Auto SEM method, can increase the detection range of plankton related to drowning and improve the evidence power of drowning diagnosis.

Abstract
BACKGROUND Certified nursing assistants (CNAs) provide 80% to 90% of direct care and are 23 times more likely to experience aggressive behavior from residents in long-term care (LTC) facilities than in other health care settings. The purpose of this study was to describe CNAs' perceptions of workplace violence while working in LTC facilities. METHODS Ten CNAs were recruited from five LTC facilities through snowball sampling. A semi-structured interview was conducted with CNAs currently working in LTC facilities in Alabama. Question domains included (a) demographics, (b) residents' behavior, (c) behavior of residents with dementia, (d) experiences of verbal or physical violence from residents, (e) quality of care delivered, (f) coping strategies, (g) administrative support, and (h) training for dementia-related care challenges. The resulting transcripts were thematically analyzed. FINDINGS CNAs described workplace violence as part of the job. They expressed a lack of administrative support as inadequate communication and a dismissal of violence against them. They regularly experienced racially charged abuse, but the perception of abuse was moderated by the presence or absence of dementia. They described a lack of training and direction to recognize and de-escalate workplace violence. CONCLUSIONS/APPLICATION TO PRACTICE Workplace violence from residents residing in LTC facilities is an occupational health risk for CNAs. LTC facilities need a multisystem approach to reduce episodes of resident-on-CNA violence. This approach should include comprehensive training to recognize triggers of violent behavior, especially when working with individuals with dementia, as well as administrative support, and mental health resources to address the cumulative and negative consequences of racism.

Abstract
Problem: Certified nursing assistants (CNAs) are the primary providers of direct care to persons residing in long term care facilities (LTCFs), many of whom have dementia. The need to deliver direct and intimate care increases CNAs’ exposure to verbal and physical workplace violence. Purpose: To describe CNAs’ experiences of physical and verbal workplace violence experienced during direct care activities in LTCFs. Design: Qualitative. Sample & Procedure: Ten African-American CNAs (9 female, 1 male) were recruited using snowball sampling from multiple LTCFs. Interviews were recorded and transcribed. NVivo12 software was used to manage the thematic analyses. Results: The identified themes were: 1) CNAs’ perception that verbal and physical abuse was “part of the job” and unavoidable; 2) CNAs’ feelings of minimization of the abuse by administration; and 3) inadequate CNA training to recognize and de-escalate triggers of verbal and physical violence, notably care-resistant behavior. Conclusion: The combination of institutional tolerance of workplace violence, coupled with CNAs’ insufficient training in de-escalating volatile interactions with cognitively-impaired residents, is creating an unfavorable, possibly dangerous, workplace environment for CNAs. Implications: As more states elevate assaults on healthcare workers to felony crimes, there is an emerging risk of criminalizing dementia-related behavior in an attempt to address workplace violence. Interventions focused on helping CNAs recognize and de-escalate care-resistant behavior are necessary for violence prevention programs in LTCFs. Limitations: CNAs may have self-censored and under-described the severity of their experiences during face-to-face interviews, even with confidentiality protocols and the practice of off-site interviews.

Abstract
AIM Fusarium oxysporum is the primary pathogen causing root rot disease that severely affects cultivation of jujube fruit in the Xinjiang province of China. The aim of this study was to identify endophytic bacteria in healthy jujube organs that could effectively suppress F. oxysporum growth. METHODS AND RESULTS Different plant organs (leaves, twigs and roots) were collected from healthy Chinese jujube cultivated in southern Xinjiang province of China. The endophytic bacterium Brevibacterium halotolerans JZ7 was selected for its strong antagonistic activity and growth-promoting characteristics. Gas-chromatography mass-spectrometry analysis showed that acetoin, 2,3-butanediol and fenretinide were the three dominant volatile organic compounds produced by strain JZ7. Fenretinide strongly suppressed spore germination of F. oxysporum in vitro. Pot experiments showed that strain JZ7 colonized both the roots and rhizosphere soil of Chinese jujube and significantly reduced F. oxysporum level in jujube rhizosphere soil. CONCLUSION We demonstrated that B. halotolerans JZ7 can be developed into a biological control agent to combat root rot disease of Chinese jujube in the Xinjiang province of China. SIGNIFICANCE AND IMPACT OF THE STUDY The suggested strategy for biological control of jujube root rot disease is fully in accordance with the current principles of sustainability.

Abstract
Background Prophylactic transarterial chemoembolization (p-TACE) is strongly recommended for hepatocellular carcinoma (HCC) patients with microvascular invasion (MVI), but the potential beneficiaries remain controversial. Methods Data of HCC patients with MVI who underwent R0 resection between December 2013 and December 2015 were identified through the primary liver cancer big data. Disease-free survival (DFS) and overall survival (OS) were compared between patients who received p-TACE or not using Kaplan–Meier survival curves before and after propensity scoring match (PSM). Results A total of 695 patients were eligible for this study, including 199 patients (28.6%) receiving p-TACE and 496 patients (71.4%) receiving resection alone. In the crude cohort, median DFS and OS were longer in the p-TACE group than those in the non-TACE group without significant differences (25.0 months vs 24.2 months, P=0.100; 48.0 months vs 46.5 months, P=0.150; respectively), but significant differences were observed both in DFS and OS (both P<0.05) after 1:1 PSM. p-TACE was identified as one of the independent risk factors of both DFS and OS using multivariate analysis in the matched cohort (HR=0.69, 95% CI=0.54–0.88; HR=0.66, 95% CI=0.50–0.88; respectively). Subgroup analysis showed that p-TACE could beneficiate patients if they were male, aged ≥50 years old, had HBV infection, preoperative AFP level ≥400 ng/mL, Child-Pugh grading A, no transfusion, single tumor, tumor diameter ≥5cm, Edmondson–Steiner grading I/II, capsule, or BCLC stage A, CNLC stage Ib, AJCC stage II both in DFS and OS (all P<0.05). Conclusion With the current data, we concluded that not all HCC patients with MVI would be benefited from p-TACE, and p-TACE could benefit patients with “middle risk” according to the current staging systems.

Abstract
OBJECTIVES The US has among the world's strictest automobile emission standards, but it is now loosening them. It is unclear where a nation should draw the line between the associated cost burden imposed by regulations and the broader societal benefits associated with having cleaner air. Our study examines the health benefits and cost-effectiveness of introducing stricter vehicle emission standards in France and Italy. STUDY DESIGN Quasi-experimental study. METHODS We used cost-effectiveness modeling to measure the incremental quality-adjusted life years (QALYs) and cost (Euros) of adopting more stringent US vehicle emission standards for PM2.5 in France and Italy. RESULTS Adopting Obama era US vehicle emission standards would likely save money and lives for both the French and Italian populations. In France, adopting US emission standards would save €1000 and increase QALYs by 0.04 per capita. In Italy, the stricter standards would save €3000 and increase QALYs by 0.31. The results remain robust in both the sensitivity analysis and probabilistic Monte Carlo simulation model. CONCLUSIONS Adopting more stringent emission standards in France and Italy would save money and lives.

Abstract
Abstract
Introduction
SMS is a rare neurodevelopmental disorder that manifests with craniofacial abnormalities, behavioral disturbances, and a severe sleep disorder. It has been reported that many SMS patients have an inverted melatonin secretion pattern (peaking during the daytime) although a small minority have near normal patterns. The goal of this study was to better characterize the intra- and inter-patient variability of melatonin secretion patterns and investigate a potential relationship with sleep behavior in SMS patients.
Methods
In this observational study, sleep behaviors of patients (N=8, 1 female, ages: 7 - 35) with SMS were characterized through caretaker surveys. On 3 separate occasions, patients had hourly serum melatonin levels sampled for 36 hours. From these data, peak serum melatonin concentration and time of peak concentration were determined. Inter- and intra-patient variability was characterized by zero lag correlation of the melatonin concentration timeseries across and within patients, respectively. The relationship between peak melatonin concentration, peak time, and sleep latency was analyzed by a generalized linear model, GLM.
Results
Peak melatonin concentrations varied across SMS patients with a range of 3.55pg/ml - 49.65pg/ml (mean 14.18 ± 15.19pg/ml). Time of peak melatonin concentrations ranged from 0400h-2100h (mean 1422 ± 6h). Correlation coefficients characterizing intra-patient variability ranged from -0.0098 to 0.89 (mean 0.55 ± 0.2533). Correlation coefficients characterizing inter-patient variability ranged from -0.75 to 0.79 (mean of 0.18 ± 0.52). Sleep latency ranged from 8.4min - 36.35min (mean of 21.99 ± 9.77 min). GLM analysis demonstrated a significant, positive effect of peak time with sleep latency (p=0.022).
Conclusion
Consistent with previous findings, our study confirms that SMS patients have abnormal circadian rhythms. Our work extends this body of literature by demonstrating a significant degree of inter-patient variability with relatively stable intra-patient variability. Preliminary evidence suggests that the timing of melatonin peak may be related to sleep onset latency.

Abstract
Abstract
Introduction
Smith-Magenis Syndrome (SMS) is a rare (1/15,000 - 25,000 births) neurodevelopmental disorder resulting from an interstitial deletion of chromosome 17p11.2, or from a point mutation in the RAI1 gene. Severe sleep disorder is almost universal in patients with SMS and poses a significant challenge to patients and their families. Tasimelteon improved sleep symptoms in a randomized, double-blind, two-period, crossover study; and here we show that this effect persists for up to four years in an open-label extension. To our knowledge, this is the largest interventional study of SMS patients to date.
Methods
Following the 4-week crossover study, all eligible participants had the option to enroll in an open-label extension. 31/39 (79.4%) of all individuals who participated in the efficacy study have continued on tasimelteon treatment. Participants in the open-label extension provided daily diary sleep quality (DDSQ), and daily diary total sleep time (DDTST) measures via parental post sleep questionnaire and characterized behavior using the Aberrant Behavior Checklist (ABC).
Results
In the open-label extension, tasimelteon continued to show improvement in the primary endpoints of 50% worst sleep quality (mean = 0.7, SD = 0.94) and 50% worst total nighttime sleep duration (mean = 53.3, SD = 59.01) when compared to baseline. Tasimelteon also improved overall sleep quality (mean=0.7, SD=0.83) and overall total nighttime sleep duration (mean = 51.9, SD=53.03). ABC scores also improved with tasimelteon (mean= -16.3, SD = 15.82).
Conclusion
Tasimelteon continues to demonstrate persistence in efficacy (longest approximately 4 years) with similar magnitudes observed in the 4-week crossover study for sleep quality and total sleep time. Interestingly, daytime behavior also demonstrates long-term improvement in patients with SMS treated with tasimelteon. These results further confirm tasimelteon as a novel therapy for the treatment of sleep disorders in patients with SMS and may provide benefit for behavioral symptoms.

Abstract
BACKGROUND Long noncoding RNAs (lncRNAs) are the chief products of human transcriptomes and have a major function in mediating gene expression. Abnormal lncRNA levels have been detected in gastric cancer. However, changes in lncRNA expression in advanced gastric adenocarcinoma (GA) are largely unexplored. METHODS We studied the expression of lncRNAs and mRNAs in 6 advanced resected GA (ARGA) tissues using a lncRNA microarray chip. RESULTS Among 22,870 lncRNAs expressed in ARGA and paired nonneoplastic tissues (non-GA), 1,769 and 1,710 were up- or downregulated, respectively, in all 6 ARGA tissues (≥ 2.0-fold, p < 0.05). The expression of 5 differentially expressed lncRNAs, HNF1A-AS1, RP11-62F24.2, GAS5, MALAT1, and H19 were randomly selected to be measured in 47 patients using real-time quantitative reverse transcription PCR (qRT-PCR), and the data were consistent with those obtained from the microarray chip. Analysis of their nearby coding genes (mRNAs) revealed that the main associated GO (gene ontology) classes were genes that regulate cellular metabolic processes, protein binding and receptor binding, whereas the main associated pathways were MAPK signaling, which regulates cell proliferation and differentiation and the apoptosis pathway, which is cancer-related. Some (n = 37) differentially expressed lncRNAs had direct annotated functions; among these lncRNAs, 27 were associated with cancer, cancer pathways, oncogenes, and tumor suppressor genes and with cell development and differentiation. CONCLUSIONS Expression differences in lncRNAs exist between advanced GA and noncancerous gastric tissues, so lncRNA expression patterns may explain gastric carcinogenesis and progression as well as serve as candidate biomarkers for the treatment of GA.

Abstract
The genetic background of Atopic Dermatitis (AD) with chronic pruritus is complex. Filaggrin (FLG) is an essential gene in the epidermal barrier formation s. Loss-of-function (LOF) variants in FLG associated with skin barrier dysfunction constitute the most well-known genetic risk factor for AD. In this study, we focused on the frequency and effect of FLG loss-of-function variants in association with self-reported age-of-onset of AD. The dataset consisted of 386 whole-genome sequencing (WGS) samples. We observe a significant association between FLG LOF status and age-of-onset, with earlier age of onset of AD observed in the FLG LOF carrier group (p-value 0.0003, Wilcoxon two-sample test). We first tested this on the two most prevalent FLG variants. Interestingly, the effect is even stronger when considering all detected FLG LOF variants. Having two or more FLG LOF variants associates with the onset of AD at 2 years of age. In this study, we have shown enrichment of rare variants in the EDC region in cases compared with controls. Age-of-onset analysis shows not only the effect of the FLG and likely EDC variants in terms of the heightened risk of AD, but foremost enables to predict early-onset, lending further credence to the penetrance and causative effect of the identified variants. Understanding the genetic background and risk of early-onset is suggestive of skin barrier dysfunction etiology of AD with chronic pruritus

Abstract
Radixin is an important member of the Ezrin-Radixin-Moesin protein family that is involved in cell invasion, metastasis and movement. microRNA (miR)-200b is a well-studied microRNA associated with the development of multiple tumors. Previous bioinformatics analysis has demonstrated that miR-200b has a complementary binding site in the 3'-untranslated region of radixin mRNA. The present study aimed to investigate the role of miR-200b in regulating radixin expression, cell proliferation and invasion in breast cancer. Breast cancer tissues at different Tumor-Node-Metastasis (TNM) stages were collected; breast tissues from patients with hyperplasia were used as a control. miR-200b and radixin mRNA expression levels were tested by reverse transcription-quantitative PCR. Radixin protein expression was detected by western blotting. The highly metastatic MDA-MB-231 cells were divided into four groups and transfected with a miR-negative control (NC), miR-200b mimic, small interfering (si)RNA-NC or siRNA targeting radixin. Cell invasion was evaluated by Transwell assay and cell proliferation was assessed by 5-ethynyl-2'-deoxyuridine staining. Compared with the control group, radixin mRNA expression was significantly higher in breast cancer tissues and increased with TNM stage. miR-200b expression levels exhibited the opposite trend. Radixin mRNA expression in breast cancer cells was notably higher, whereas miR-200b expression was lower compared with that in normal breast epithelial MCF-10A cells. The expression of radixin was higher, whereas miR-200b was lower in MDA-MB-231 cells compared with that in MCF-7 cells. miR-200b mimic or siRNA-radixin transfection downregulated the expression of radixin in MDA-MB-231 cells and attenuated the invasive and proliferative abilities of these cells. miR-200b-knockdown and radixin overexpression were associated with enhanced cell invasion in breast cancer. In conclusion, miR-200b regulates breast cancer cell proliferation and invasion by targeting radixin expression.

Abstract
Abstract Objective To discuss the application value of diatom examination in lung tissue for the forensic diagnosis of drowning. Methods The experimental animals were divided randomly into drowning, postmortem submergence and dying on land group. Diatoms in lung tissue and drowning fluid were analyzed quantitatively by microwave digestion-vacuum filtration-automated scanning electron microscopy diatom examination method. The ratios of content of diatoms in lung tissue and drowning fluid (CL/CD ratio) were recorded. Results The CL/CD ratios of experimental rabbits in the drowning group (5.82±3.50) were much higher than that of postmortem submergence group (0.47±0.35); the CL/CD ratios of different parts of the lung lobes of experimental pigs in the drowning group were higher than that of postmortem submergence group (P<0.05); in seawater, brackish water, river fresh water and lake fresh water, the CL/CD ratios of experimental pigs in the drowning group were higher than that of postmortem submergence group (P<0.05). In animal experiments, all the cases with CL/CD ratio >1.6 were from drowning group. Conclusion CL/CD ratio is an indicator with good application prospects in the diagnosis of drowning.
