Abstract
OBJECTIVE To examine socio-demographic disparities in food insecurity during the COVID-19 pandemic and the association between food insecurity and mental health among US adults overall and communities vulnerable to food insecurity. METHODS A cross-sectional study was conducted using the 2020-2021 National Health Interview Survey of 57,456 US adults. Weighted multivariable logistic regression models were used to estimate the association between food insecurity and anxiety or depression symptoms in overall US adults and subgroups including young adults (18-34 years), females, Hispanic people, non-Hispanic Black people, individuals with prior COVID-19 infection, the unemployed, low-income participants, participants with children, and Supplemental Nutrition Assistance Program (SNAP) participants. RESULTS Young or middle age, female sex, Hispanic/non-Hispanic Black/other race/ethnicity, lower education level, unmarried/other marital status, unemployment, being below the federal poverty level, and greater number of persons in the household were associated with food insecurity (AOR ranged from 1.35 to 2.70, all p < 0.05). Food insecurity was independently associated with anxiety (AOR = 2.67, 99 % CI: 2.33, 3.06) or depression (AOR = 3.04, 99 % CI: 2.60, 3.55) symptoms in the overall adults. Significant associations between food insecurity and anxiety or depression symptoms were also observed in all subgroups (AOR ranged from 1.95 to 3.28, all p < 0.0001). Compared with overall adults, the magnitude of the association was greater for participants with children, females (for depression only), and non-Hispanic Black people (for depression only). LIMITATIONS The cross-sectional design prevents inference of causality. CONCLUSIONS Comprehensive policies are needed to ensure accessible and affordable food resources to reduce disparities in food insecurity and improve mental health, especially for those socioeconomically disadvantaged communities.

Abstract
Detecting early-stage esophageal squamous cell carcinoma (ESCC) and precancerous lesions is critical for improving survival. Here, we conduct whole-genome bisulfite sequencing (WGBS) on 460 cfDNA samples from patients with non-metastatic ESCC or precancerous lesions and matched healthy controls. We develop an expanded multimodal analysis (EMMA) framework to simultaneously identify cfDNA methylation, copy number variants (CNVs), and fragmentation markers in cfDNA WGBS data. cfDNA methylation markers are the earliest and most sensitive, detectable in 70% of ESCCs and 50% of precancerous lesions, and associated with molecular subtypes and tumor microenvironments. CNVs and fragmentation features show high specificity but are linked to late-stage disease. EMMA significantly improves detection rates, increasing AUCs from 0.90 to 0.99, and detects 87% of ESCCs and 62% of precancerous lesions with >95% specificity in validation cohorts. Our findings demonstrate the potential of multimodal analysis of cfDNA methylome for early detection and monitoring of molecular characteristics in ESCC.

Abstract
BACKGROUND Studies on the association between e-cigarette use and mental health are mostly among adolescents and young adults, leaving limited evidence of this association among general US adults. Besides, few studies have examined how e-cigarette use or dual use of e-cigarette and combustible cigarette is related to cognitive function. METHODS Cross-sectional data of 56,734 adults from the 2020-2021 National Health Interview Survey were analyzed. Weighted multivariable logistic regression models were applied to examine the independent association between e-cigarette use or dual use and anxiety symptoms, depression symptoms, serious psychological distress (SPD), and cognitive impairment. RESULTS Compared with never e-cigarette users, current e-cigarette users had 2.10-fold (95 % CI: 1.84, 2.39), 2.53-fold (95 % CI: 2.13, 3.00), 2.02-fold (95 % CI: 1.47, 2.76), and 2.00-fold (95 % CI: 1.47, 2.72) higher odds of reporting anxiety symptoms, depression symptoms, SPD, and cognitive impairment, respectively. Former e-cigarette use was also associated with all three mental conditions and cognitive impairment (AOR ranged from 1.38 to 2.53, all P < 0.01). Dual users were more likely to report all three mental conditions and cognitive impairment than those who never used combustible cigarette and e-cigarette (AOR ranged from 1.89 to 2.83, all P < 0.01). Dual users also had a greater likelihood of having anxiety or depression symptoms than exclusive combustible cigarette users (AOR ranged from 1.46 to 1.47, all P < 0.01). CONCLUSIONS E-cigarette use or dual use is associated with poor mental health and cognitive impairment among US adults. Regulations on e-cigarette use are needed to prevent mental illness and improve cognitive function.

Abstract
BACKGROUND The hippocampus is a heterogeneous structure, comprising histologically and functionally distinguishable hippocampal subfields. The volume reductions in hippocampal subfields have been demonstrated to be linked with Alzheimer's disease (AD). The aim of our study is to investigate the hippocampal subfields' genetic architecture based on the Alzheimer's Disease Neuroimaging Initiative (ADNI) data set. METHODS After preprocessing the downloaded genetic variants and imaging data from the ADNI database, a co-sparse reduced rank regression model was applied to analyze the genetic architecture of hippocampal subfields volumes. Homology modeling, docking, molecular dynamics simulations, and Co-IP experiments for protein-protein interactions were used to verify the function of target protein on hippocampal subfields successively. After that, the association analysis between the candidated genes on the hippocampal subfields volume and clinical scales were performed. RESULTS The results of the association analysis revealed five unique genetic variants (e.g., ubiquitin-specific protease 10 [USP10]) changed in nine hippocampal subfields (e.g., the granule cell and molecular layer of the dentate gyrus [GC-ML-DG]). Among five genetic variants, USP10 had the strongest interaction effect with BACE1, which affected hippocampal subfields verified by MD and Co-IP experiments. The results of association analysis between the candidated genes on the hippocampal subfields volume and clinical scales showed that candidated genes influenced the volume and function of hippocampal subfields. CONCLUSIONS Current evidence suggests that hippocampal subfields have partly distinct genetic architecture and may improve the sensitivity of the detection of AD.

Abstract
Pressure ulcers (PUs) are economically burdensome medical conditions. Early changes in pressure ulcers are associated with erythema. In this study, bioelectrical impedance was used to measure the differences between PUs and blanchable erythema. We divided 21 ICR mice into three groups: control, 1000 mmHg-1h, and 1000 mmHg-6h. Healthy skin, blanchable erythema, and PUs were induced on the dorsal skin. The results indicated an immediate increase in impedance, resistance, and reactance values in the pressure group after release, followed by a subsequent decrease until two days after release. Compared with the control group, impedance and reactance significantly increased by 30.9% (p < 0.05) and 30.1% (p < 0.01), respectively, in the 6 h-loading group immediately after release. One and two days after release, the 1 h-loading and 6 h-loading groups exhibited significantly different degrees of decline. One day after release, impedance and resistance decreased by 30.2% (p < 0.05) and 19.8% (p < 0.05), respectively, in the 1 h-loading group; while impedance, resistance, and reactance decreased by 39.2% (p < 0.01), 26.8% (p < 0.01), and 45.7% (p < 0.05), respectively, in the 6 h-loading group. Two days after release, in the 1 h-loading group, impedance and resistance decreased by 28.3% (p < 0.05) and 21.7% (p < 0.05), respectively; while in the 6 h-loading group, impedance, resistance, and reactance decreased by 49.8% (p < 0.001), 34.2% (p < 0.001), and 59.8% (p < 0.01), respectively. One and two days after release the pressure group reductions were significantly greater than those in the control group. Additionally, we monitored changes during wound healing. Distinguishing early PUs from blanchable erythema by noninvasive bioelectrical impedance technology may have applications value in early assessment of PUs.

Abstract
The inflammatory response is one of the general symptoms that accompany tumorigenesis, the pro-inflammatory factors cyclooxygenase-2 (COX-2) and COX-2-derived prostaglandin-2 (PGE-2) in the inflammatory environment surrounding tumors possess promoting tumor development, metastasis and angiogenesis effects. In addition, the hypoxic environment of tumors severely limits the effectiveness of photodynamic therapy (PDT). In this study, a universal extracellular-intracellular 'on-demand' release nanomedicine DOX@PDA-ICG@MnO2@GN-CEL was developed for the combined fight against malignant tumors using a spatiotemporal controlled gelatin coated polydopamine (PDA@GN) as the carrier and loaded with the chemotherapeutic drug doxorubicin (DOX), the photosensitizer indocyanine green (ICG), the PDT enhancer MnO2and the anti-inflammatory drug celecoxib (CEL) individually. Our results showed that DOX@PDA-ICG@MnO2@GN-CEL could release CEL extracellularly by matrix metalloproteinase-2 response and inhibit the COX-2/PGE-2 pathway, reduce chemotherapy resistance and attenuate the concurrent inflammation. After entering the tumor cells, the remaining DOX@PDA-ICG@MnO2released DOX, ICG and MnO2intracellularly through PDA acid response. MnO2promoted the degradation of endogenous H2O2to generate oxygen under acidic conditions to alleviate the tumor hypoxic environment, enhance PDT triggered by ICG. PDA and ICG exhibited photothermal therapy synergistically, and DOX exerted chemotherapy with reduced chemotherapy resistance. The dual responsive drug release switch enabled the chemotherapeutic, photothermal, photodynamic and anti-inflammatory drugs precisely acted on different sites of tumor tissues and realized a promising multimodal combination therapy.

Abstract
Due to the highly environment-dependent biodegradation and uncontrolled degradation period, the long-run feasibility and effectiveness of biodegradable polymers are extensively questioned to solve plastics waste accumulation and pollution problems. This work physically incorporated lipase PS from Burkholderia cepacian on cellulose nanocrystals (CNC) and embedded it in polycaprolactone (PCL) to construct stable and controllable interfacial microenvironment between CNC and PCL for the reinforcement and controllable self-driven biodegradation. The physical adsorption of lipase PS on CNC was studied by monitoring the surface charge and particle size. FT-IR spectra confirmed the successful incorporation of lipase PS and CNC. Compared with CNC, protein-modified CNC had a higher maximum thermal decomposition temperature of 345 °C and lower interfacial tension of 11 mN/m with PCL which provided PCL composites with higher nucleation efficiency and tensile elongation of 1086 % at break. In addition, only 0.67 % embedded lipase PS completely hydrolyzed PCL membranes in <140 h. The post-compression molding at 80-100 °C had negligible influence on the lipase activity, which indicated that CNC could protect the lipase from inactivation in polymer extrusion and compression. This work also highlighted protein-modified CNC as a new technology for polymer reinforcement.

Abstract
Esophageal squamous cell carcinoma (ESCC) is an aggressive epithelial malignancy with poor prognosis. Interestingly, ESCC is strongly characterized by a male-predominant propensity. Our previous study showed that androgen receptor (AR) orchestrated a transcriptional repression program to promote ESCC growth, but it remains unclear whether AR can also activate oncogenic signaling during ESCC progression. In this study, by analyzing our previous AR cistromes and androgen-regulated transcriptomes, we identified uridine diphosphate glucuronosyltransferase family 2 member B15 (UGT2B15) as a bona fide target gene of AR. Mechanistically, AP-1 cofactors played important and collaborative roles in AR-mediated UGT2B15 upregulation. Functional studies have revealed that UGT2B15 promoted invasiveness in vitro and lymph node metastasis in vivo. UGT2B15 was partially responsible for the AR-induced invasive phenotype in ESCC cells. Importantly, simultaneous blocking of AP-1 and AR resulted in stronger inhibition of cell invasiveness compared to inhibiting AP-1 or AR alone. In conclusion, our study reveals the molecular mechanisms underlying the AR-driven ESCC invasion and suggests that the AR/AP1/UGT2B15 transcriptional axis can be potentially targeted in suppressing metastasis in male ESCC patients.

Abstract
Abl is a nonreceptor tyrosine kinase involved in a variety of disease pathways such as rheumatic immune. Full-length Abl protein consists of a catalytic tyrosine kinase (TK) domain as well as two regulatory Src homology domains 2 and 3 (SH2 and SH3, respectively); the latter recognizes and binds to those natural proline-rich peptide segments containing a PxxP motif on the protein surface of its interacting partners. However, natural peptides cannot bind effectively to the modular domain in high affinity and strong selectivity due to their small size and broad specificity. Here, a synthetic proline-rich peptide p41 was used as template; its structural diversity was extended by combinationally replacing the Pro0 and Pro+3 residues with a number of N-substituted amino acids. Consequently, peptide affinity change upon the replacement was derived to create a systematic N-substituting perturbation profile, from which we identified several N-substitution combinations at the Pro0 and Pro+3 residues of p41 PxxP motif that may moderately or significantly improve the peptide binding potency to Abl; they represent potent peptoid binders of Abl SH3 domain, with affinity improved considerably relative to p41. More significantly, the designed potent peptoids were also found to exhibit a good SH3-selectivity for their cognate Abl over other noncognate nonreceptor tyrosine kinases, with S = 9.7-fold.

Abstract
To examine recent trends in unmet health care needs among US adults, cross-sectional data of 93,047 adults from 2019 to 2021 National Health Interview Survey were analyzed. The weighted prevalence and changes in prevalence of cost-related or COVID-19-related unmet health care needs were estimated, first overall and then stratified by socio-demographic characteristics. The prevalence of cost-related unmet health care needs was 8.3% (95% CI: 7.8%, 8.8%) in 2019, which significantly decreased to 6.6% (95% CI: 6.2%, 7.0%) in 2020 and 6.1% (95% CI: 5.7%, 6.4%) in 2021. Across most socio-demographic groups, the prevalence of cost-related unmet health care needs significantly decreased between 2019 and 2020 (absolute changes ranged from -7.4% to -1%) and between 2019 and 2021 (absolute changes ranged from -10.5% to -1.2%), with significant reductions among uninsured adults, adults below the federal poverty level, and Hispanics. The prevalence of COVID-19-related unmet health care needs was 15.7% (95% CI: 14.9%, 16.4%) in 2020, which decreased to 11.9% (95% CI: 11.5%, 12.4%) in 2021. The prevalence of COVID-19-related unmet health care needs significantly decreased across most socio-demographic groups between 2020 and 2021 (absolute changes ranged from -4.9% to -2.4%), with significant reductions among the older, the unemployed, non-Hispanic Black adults, and adults with education level ≥ college. Overall, a modest decrease in the prevalence of both cost-related and COVID-19-related unmet health care needs was observed between 2019 and 2021. However, the fact that over 10% of US adults had unmet health care needs because of the COVID-19 pandemic is still concerning, warranting continued surveillance.

Abstract
BACKGROUND Studies have established associations between combustible cigarette use and diabetes. However, there is limited evidence on the association between e-cigarette use or dual use of e-cigarettes and combustible cigarettes and diabetes. METHOD With cross-sectional data of 5101 U.S. adults from the National Health and Nutrition Examination Survey, this study examined how e-cigarette use or dual use was related to diabetes, prediabetes, or insulin resistance. The presence of diabetes or prediabetes was determined by fasting glucose level, hemoglobin A1C (HbA1c), or the use of prescribed medications. Insulin resistance was assessed by the homeostatic model (HOMA-IR). The independent association between e-cigarette use or dual use and outcomes was examined using weighted multivariable logistic regression models controlling for potential confounders. RESULTS Of all participants, 6.3% were current e-cigarette users and 17.1% were former e-cigarette users. In the fully adjusted model, e-cigarette use was not associated with prediabetes or diabetes (P>0.05). However, former e-cigarette users were 22% (95% CI: 1.00, 1.84) more likely to report higher HOMA-IR (Q3 vs Q1) than never e-cigarette users. Among ever combustible cigarette users, current e-cigarette users and former e-cigarette users were 63% (95% CI: 1.00, 2.91) and 64% (95% CI: 1.04, 2.59) more likely to report higher HOMA-IR than never e-cigarette users, respectively. There was no significant association between dual use and diabetes, prediabetes, or insulin resistance (P>0.05). CONCLUSIONS E-cigarette use may be associated with insulin resistance. Our findings may inform future tobacco control policies and longitudinal studies assessing insulin resistance associated with e-cigarette use.

Abstract
PURPOSE Examine associations between e-cigarette use or dual use of e-cigarette and combustible cigarette and metabolic syndrome (MetS). METHODS Cross-sectional data of 5121 U.S. adults from the National Health and Nutrition Examination Survey were analyzed. Weighted multivariable Poisson regression models were used to examine associations between e-cigarette use or dual use and MetS and its components. Prevalence ratios (PRs) with 95% confidence intervals (95% CI) were estimated. RESULTS Current and former e-cigarette users were 30% (95% CI: 1.13, 1.50) and 15% (95% CI: 1.03, 1.28) more likely to have MetS than never e-cigarette users. Current or former e-cigarette use was also associated with elevated triglycerides, reduced high-density lipoprotein (HDL) cholesterol, and elevated blood pressure (AOR ranged from 1.15 to 1.42, all P < 0.05). The prevalence of MetS for dual users was 1.35-fold (95% CI: 1.15, 1.58) higher than that for never smokers and 1.21-fold (95% CI: 1.00, 1.46) higher than that for combustible cigarette-only users. Dual users were also more likely to report elevated triglycerides and reduced HDL cholesterol than never smokers or combustible cigarette-only users (all P < 0.05). CONCLUSIONS E-cigarette use or dual use is associated with MetS. Our findings may inform tobacco control policies regarding regulations of e-cigarette use.

Abstract
Objective To develop a logistic regression model that combines clinical and radiological parameters for prediction of complicated appendicitis. Methods 248 patients with histologically proven uncomplicated (n = 214) and complicated (n = 34) acute appendicitis were analyzed retrospectively. All patients had undergone a presurgical abdominal and/or pelvic computed tomography (CT) scan, assessed by two radiologists. A model using univariate and multivariate logistic regression analyses was developed, and the strength of association between independent predictors and complicated acute appendicitis was evaluated by adjusted odds radio. Clinical parameters were gender, age, anorexia, vomiting, duration of symptoms, right lower abdominal quadrant (RLQ) tenderness, rebound tenderness, body temperature, white blood cell (WBC) count, and neutrophil ratio. Radiological parameters were appendix diameter, appendicolith, caecal wall thickening, mesenteric lymphadenopathy, extraluminal air, abscess, fat stranding, and periappendicular fluid. Results Four features (body temperature>37.2 °C, vomiting, appendicolith, and periappendiceal fluid) were included in the logistic regression model, and yielded an area under the curve (AUC) of 0.87 (95% confidence interval (CI), 0.80-0.93), sensitive of 88%, and specificity of 74%. Conclusion The logistic regression model makes an accurate and simple prediction of complicated appendicitis possible.

Abstract
Introduction The purpose of this study was to examine the sociodemographic and health-related factors associated with food insecurity and the association between food insecurity and COVID-19 infection using a nationally representative sample in the U.S. Methods Cross-sectional data of 61,050 adults (aged ≥18 years) from the 2020 and 2021 National Health Interview Survey were analyzed. Food insecurity was measured by the 10-item U.S. Department of Agriculture Food Security Survey Module. Weighted multivariable logistic regression models were used to estimate associations with food insecurity. Results A total of 6.8% of the National Health Interview Survey participants lived in food-insecure households, and 18.9% tested positive for COVID-19 infection. Young (aged 18-34 years) or middle (aged 35-64 years) age, female sex, minor race/ethnicity (Hispanic/non-Hispanic Black/non-Hispanic Asian/others), education level less than high school, unmarried status, unemployment, poverty (below the federal poverty level), having no health insurance, a larger number of adults and children in the household, poorer self-reported health status, and the presence of chronic conditions were significantly associated with food insecurity (AOR ranged from 1.20 to 3.15, all p<0.0001). Food insecurity was independently associated with positive COVID-19 infection (AOR=1.25, 95% CI=1.11, 1.40), controlling for sociodemographic and health-related factors. The greatest magnitude of the association was observed for the non-Hispanic Black participants (AOR=1.47, 95% CI=1.15, 1.88), female participants (AOR=1.44, 95% CI=1.20, 1.71), and those below the federal poverty level (AOR=1.39, 95% CI=1.12, 1.73) across all the subgroups. Conclusions Food insecurity disproportionately affected vulnerable subgroups such as young adults, female individuals, minority race/ethnicity groups, and those with lower socioeconomic status, and was associated with positive COVID-19 infection. Policies addressing food insecurity may help to reduce the likelihood of COVID-19 infection, especially for those vulnerable subgroups.

Abstract
There has been great interest in the enzymatic cascade amplification strategy for the electrochemical detection of circulating tumor cells (CTCs). In this work, we designed a highly efficient enzymatic cascade reaction based on a multiwalled carbon nanotubes-chitosan (MWCNTs-CS) composite for detection of CTCs. A high electrochemical effective surface area was obtained for a MWCNTs-CS-modified glassy carbon electrode (GCE) for loading glucose oxidase (GOD), as well as a high loading rate and high electrical activity of the enzyme. As a 'power source', the MWCNTs-CS composites provided a strong driving power for horseradish peroxidase (HRP) on the surface of polystyrene (PS) microspheres, which acted as probes for capturing CTCs and allowed the reaction to proceed with further facilitation of electron transfer. Aptamer, CTCs, and PS microspheres with HRP and anti-epithelial cell adhesion molecule (anti-EpCAM) antibody were assembled on the MWCNTs-CS/GCE to allow for the modulation of enzyme distance at the micrometer level, and thus ultra-long-range signal transmission was made possible. An ultrasensitive response to CTCs was obtained via this proposed sensing strategy, with a linear range from 10 cell mL-1 to 6 × 106 cell mL-1 and a detection limit of 3 cell mL-1. Moreover, this electrochemical sensor possessed the capability to detect CTCs in serum samples with satisfactory accuracy, which indicated great potential for early diagnosis and clinical analysis of cancer.

Abstract
BACKGROUND Using a nationally representative sample, this study aimed to examine (1) socio-demographic and health-related disparities in cognitive impairment, (2) the association between food insecurity and cognitive impairment, and (3) the mediation role of anxiety or depression in the pathway between food insecurity and cognitive impairment. METHODS Cross-sectional data of 28,508 adults from the 2020 National Health Interview Survey were analyzed. Multivariable logistic regression models were used to estimate associations with cognitive impairment. Mediation analyses were conducted using the four-way decomposition method under a counterfactual framework. RESULTS Disparities in cognitive impairment were observed across socio-demographic and health-related characteristics (all p < 0.0001). Food insecurity was significantly associated with cognitive impairment in the overall population and the magnitude of the association was greater for the young or middle-aged, females and non-Hispanic Blacks than the general population (AOR ranged from 1.19 to 2.54, all p < 0.01). With anxiety as a mediator, 28.66 % of the total effect of food insecurity on cognitive impairment was attributable to mediation only, and 22.39 % was attributable to interaction (between food insecurity and anxiety) and mediation. With depression as a mediator, 22.33 % of the total effect was attributable to mediation only, and 16.00 % was attributable to interaction (between food insecurity and depression) and mediation. LIMITATIONS The cross-sectional design prevents inference of causality. CONCLUSIONS Ensuring available and adequate food resources is important to prevent adverse cognitive outcomes. Clinical interventions or treatments for anxiety or depression may help improve cognitive function.

Abstract
BACKGROUND This study aims to examine how the presence of chronic conditions or positive COVID-19 infection (as exposures) is related to food insecurity (as an outcome) in the older population and whether there is a dose-response relationship between the number of chronic conditions and the severity of food insecurity. METHODS Cross-sectional data of 17,977 older adults (≥ 65 years) from the 2020-2021 National Health Interview Survey were analyzed. Chronic conditions included physical health conditions (i.e., arthritis, coronary heart diseases, hypertension, stroke, prediabetes, diabetes, asthma, chronic obstructive pulmonary disease, and disability) and mental health conditions (i.e., anxiety and depression disorder). COVID-19 infection status was determined by a self-reported diagnosis of COVID-19. Household food insecurity was measured using the 10-item US Department of Agriculture (USDA) Food Security Survey Module with a 30-day look-back window. Multinomial logistic regression models were used to examine the association between health conditions and food insecurity controlling for socio-demographic factors. RESULTS Our results indicated that 4.0% of the older adults lived in food-insecure households. The presence of chronic conditions was significantly associated with higher odds of being food insecure independent of socio-demographic factors (AOR ranged from 1.17 to 3.58, all p < 0.0001). Compared with participants with 0-1 chronic condition, the odds of being (low or very low) food insecure was 1.09 to 4.07 times higher for those with 2, or ≥ 3 chronic conditions (all p < 0.0001). The severity of food insecurity significantly increased as the number of chronic conditions increased (p for trend < 0.0001). Besides, COVID-infected participants were 82% more likely to be very low food secure than the non-infected participants (AOR = 1.82, 95% CI: 1.80, 1.84). CONCLUSIONS The presence of chronic conditions or positive COVID-infection is independently associated with household food insecurity. Clinical health professionals may help identify and assist individuals at risk of food insecurity. Management and improvement of health conditions may help reduce the prevalence and severity of food insecurity in the older population.

Abstract
Alzheimer's disease (AD) is a highly heritable disease. The morphological changes of cortical cortex (such as, cortical thickness and surface area) in AD always accompany by the change of the functional connectivity to other brain regions and influence the short- and long-range brain network connections, causing functional deficits of AD. In this study, the first hypothesis is that genetic variations might affect morphology-based brain networks, leading to functional deficits; the second hypothesis is that protein-protein interaction (PPI) between the candidate proteins and known interacting proteins to AD might exist and influence AD. 600 470 variants and structural magnetic resonance imaging scans from 175 AD patients and 214 healthy controls were obtained from the Alzheimer's Disease Neuroimaging Initiative-1 database. A co-sparse reduced-rank regression model was fit to study the relationship between non-synonymous mutations and morphology-based brain networks. After that, PPIs between selected genes and BACE1, an enzyme that was known to be related to AD, are explored by using molecular dynamics (MD) simulation and co-immunoprecipitation (Co-IP) experiments. Eight genes affecting morphology-based brain networks were identified. The results of MD simulation showed that the PPI between TGM4 and BACE1 was the strongest among them and its interaction was verified by Co-IP. Hence, gene variations influence morphology-based brain networks in AD, leading to functional deficits. This finding, validated by MD simulation and Co-IP, suggests that the effect is robust.

Abstract
Objective This study aimed to determine whether sarcopenia affects the all-cause mortality rate of patients with diabetic foot ulcers (DFUs). Research design and methods The clinic-based observational study included 217 patients treated at the Department of Endocrinology, the First Affiliated Hospital of Chongqing Medical University during a 4-year period. All subjects underwent dual-energy X-ray absorptiometry to determine their body composition during hospitalization. Diagnosis of sarcopenia was based on the Baumgartner diagnostic criteria. Patients were followed up regularly by phone calls until April 1, 2019, and their survival status was recorded.Univariate and multivariate Cox risk ratio regression models were used to analyze factors influencing the all-cause mortality rate of patients with DFUs. Results Of the 217 patients, 158 people survived (82.7%), 33 died (17.3%), and 26 were lost to follow-up. The median follow-up time was 23 (Range 11-34) months. The majority of patients were male (68.6%), with a mean age of 67.29 ± 11.14 years. The 5-year survival rate was 68.3% and 45.9% for all study patients (n = 217) and sarcopenia patients (n = 81), respectively. Multivariate Cox risk regression model showed that age (HR 1.042[95%CI:1.006, 1.078], P = 0.021), sarcopenia (HR 5.051[95%CI:1.968, 12.961], P = 0.001), and serum creatinine (HR 1.007[95%CI: 1.003, 1.010], P < 0.001) were independent risk factors for all-cause mortality rate of patients with DFUs. Kaplan-Meier survival curve indicated that the survival rate of patients with sarcopenia was significantly lower than non-sarcopenia patients (P < 0.001). Conclusions Sarcopenia is an independent risk factor for all-cause mortality of patients with DFUs and hence an important prognostic factor for patients with DFUs. Active prevention and improvement of sarcopenia can potentially improve the survival outcomes of this patient population.

Abstract
IntroductionLung cancer can be masked by coexisting stable tuberculosis lesions, which may result in delayed lung cancer diagnosis and treatment. Information about pulmonary tuberculosis patients who are at high-risk of developing lung cancer is scarce. We aimed to examine the value of chest computed tomography (CT) in evaluating lung cancer in a lobe affected by stable pulmonary tuberculosis in middle-aged and elderly patients.MethodsIn this single-centered, retrospective, observational study, we enrolled 41 middle-aged and elderly patients with pulmonary tuberculosis who developed lung cancer in the same lobe from January 30, 2011 to December 30, 2020. Comparisons of the clinical and chest CT data were made with age-matched and sex-matched control groups of patients with stable pulmonary tuberculosis but no lung cancer diagnosis (n = 38).ResultsSeventeen patients in the lung cancer group (41%) were initially misdiagnosed. Compared to lesions in the control group, lesions in the lung cancer group were significantly more likely to demonstrate the following CT features: large size, vessel convergence, lobulation, spiculation, spinous protuberance, bronchial obstruction or stenosis, vacuolation, ground-glass opacification, heterogeneous or homogeneous enhancement, and gradual increase in size. Nodular enlargement showed the best diagnostic performance in the diagnosis of lung cancer in a lobe affected by tuberculosis (area under the receiver operating characteristic curve = 0.974; P <0.001; accuracy = 98.2%; sensitivity =94.7%; specificity = 100%).ConclusionChest CT might play an important role in early diagnosis of lung cancer in a lobe affected by tuberculosis. Regular CT re-examination is necessary in continuous controls monitoring of patients with stable pulmonary tuberculosis. The study indicates necessity of prospective study in this field.

Abstract
Introduction During the combined treatment of tumors, the non-interfering transportation of drugs with different solubilities and the controllable sequential release are the main challenges. Here, we reported a double-chamber “Dandelion” -like sequential drug delivery system to realize the sequential release of different drugs for treating malignant tumors synergistically. Methods After synthesizing mesoporous silica nanoparticles (MSN) by template method, a hydrophilic chemotherapy drug doxorubicin (DOX) was loaded into the channels of mesoporous silica (MSN) and locked with polydopamine (PDA) coating. Next, β-cyclodextrin (β-CDs) was decorated on PDA by Michael addition reaction, and the hydrophobic photosensitizer chlorin e6 (Ce6) was encapsulated into the hydrophobic chambers of β-CDs. Finally, AS1411 was modified on the surface of PDA and obtained DOX@MSN@PDA-β-CD/Ce6-AS1411 nanoparticles (DMPCCA) through which orthogonal loading and effective controlled release of different drugs were realized. Results Under the sequential irradiations of 808 nm and 660 nm near-infrared (NIR) laser, PDA promoted the extensive release of Ce6 firstly while playing the effect of photothermal therapy (PTT), further to achieve the effect of photodynamic therapy (PDT) of Ce6. Meanwhile, the rapid release of DOX loaded in MSN channels showed a time lag of about 5 h after Ce6 release, through which it maximized the chemotherapeutic effect. Besides, the present drug loading nano-platform combined passive tumor-targeting effect given by EPR and active tumor-targeting effect endowed by AS1411 realized PTT-PDT-chemotherapy triple mode synergistic combination. Conclusion We offer a general solution to address the key limitations for the delivery and sequential release of different drugs with different solubilities.

Abstract
Chemo-thermotherapy, as a promising cancer combination therapy strategy, has attracted widespread attention. In this study, a novel aptamer functionalized thermosensitive liposome encapsulating hydrophobic drug quercetin was fabricated as an efficient drug delivery system. This aptamer-functionalized quercetin thermosensitive liposomes (AQTSL) combined the merits of high-loading yield, sustained drug release, long-term circulation in the body of PEGylated liposomes, passive targeting provided by 100-200 nm nanoparticles, active targeting and improved internalization effects offered by AS1411 aptamer, and temperature-responsive of quercetin release. In addition, AQTSL tail vein injection combined with 42℃ water bath heating on tumor site (AQTSL+42℃)treatment inhibited the tumor growth significantly compared with the normal saline administration (p<0.01), and the inhibition rate reached 75%. Furthermore, AQTSL+42℃ treatment also slowed down the tumor growth significantly compared with QTSL combined with 42℃ administration (p<0.05), confirming that AS1411 decoration on QTSL increased the active targeting and internalization effects of the drug delivery system, and AS1411 aptamer itself might also contribute to the tumor inhibition. These data indicate that AQTSL is a potential carrier candidate for different hydrophobic drugs and tumor targeting delivery, and this kind of targeted drug delivery system combined with temperature responsive drug release mode is expected to achieve an ideal tumor therapy effect.

Abstract
Background: Although an increasing number of common variants contributing to Alzheimer’s disease (AD) are uncovered by genome-wide association studies, they can only explain less than half of the heritability of AD. Rare variant association studies (RVAS) has become an increasingly important area to explain the risk or trait variability of AD. Method: To investigate the potential rare variants that cause AD, we screened 70,209 rare variants from two cohorts of a 175 AD cohort and a 214 cognitively normal cohort from the Alzheimer’s Disease Neuroimaging Initiative database. MIRARE, a novel RVAS method, was performed on 232 non-synonymous variants selected by ANNOVAR annotation. Molecular docking and molecular dynamics (MD) simulation were adopted to verify the interaction between the chosen functional variants and BACE1. Results: MIRAGE analysis revealed significant associations between AD and six potential pathogenic genes, including PREX2, FLG, DHX16, NID2, ZnF585B and ZnF875. Only interactions between FLG (including wild type and rs3120654(SER742TYR)) and BACE1 were verified by molecular docking and MD simulation. The interaction of FLG(SER742TYR) with BACE1 was greater than that of wildtype FLG with BACE1. Conclusions: According to the literature search, bio-informatics analysis, and molecular docking and MD simulation, we find non-synonymous rare variants in six genes, especially FLG(rs3120654), that may play key roles in AD.

Abstract
To provide references for the diagnosis and treatment of congenital granular cell tumor (CGCT), by comprehensive analysis of the clinical data, histopathological and immunohistochemical results. Patients with CGCT were involede, from March 2015 to November 2020, at the Department of Oral and Maxillofacial Surgery of the First Affiliated Hospital of Zhengzhou University. A total of 6 children, aged 3-16 days, 1 male and 5 female, 5 maxillary and 1 mandibular, with maximum tumor diameter of 6-70 mm, were included. The lesions of CGCT were single and connected to the alveolar ridge by a pedicle. The surface of the tumor was covered with a vascular network, and two cases had ulcers on the surface of the tumor. All 6 cases had the tumor removed surgically and there was no recurrence or metastasis in the follow-up visit. Although CGCT is rare, it is a benign tumor and generally does not recur or metastasize after surgery, and has a good prognosis. The prenatal imaging, clinical manifestations after delivery, pathological characteristics and immunohistochemical analyses may provide reference for early diagnosis and treatment of CGCT.

Abstract
The importance of the evolutionarily conserved Argonaute (AGO) proteins has been well recognized for their involvement in the RNA interference pathways. Recent discoveries in animals demonstrated that AGOs also participate in alternative splicing (AS). Motivated by the question whether the AGO proteins are also functional in RNA splicing in plants, we searched for the introns excised through an AGO-dependent manner in Arabidopsis (Arabidopsis thaliana). RNA sequencing (RNA-seq) data analysis uncovered hundreds of the introns up- or down-regulated in the ago1 and ago4 mutants, respectively. For different genes, AGOs might play either a positive or a negative role in intron excision, which was further validated by reverse transcription-polymerase chain reaction (RT-PCR). Some introns were specifically regulated by one of the AGO proteins, while some were regulated by both AGOs. Besides, a large portion of the AGO-dependent introns were organ-specifically regulated. RNA immunoprecipitation combined with high-throughput sequencing (RIP-seq) revealed that both AGOs preferentially bound to the intronic regions, supporting their high intron binding affinities. Immunoprecipitation followed by mass spectrometry (IP-MS) was performed to identify the proteins potentially interacting with the two AGOs. Six novel interactors (two interacting with AGO1 and four with both AGOs) involved in mRNA binding were uncovered, which might facilitate AGO-intron recognition. Analysis of the RNA-seq data from the rice (Oryza sativa) ago18 mutants revealed that hundreds of the introns were expressed in an AGO18-dependent manner. In summary, our results point to the novel role of the plant AGOs in intron splicing, paving a way for further studies on the mechanisms underlying AGO-mediated RNA splicing.

Abstract
Pulmonary alveolar proteinosis (PAP) is a rare respiratory disease, but this disease has slow research progress. Animal model is an effective tool for basic research. Current PAP animal models are based on the main pathogenesis of granulocyte-macrophage colony stimulation factor (GM-CSF) signal disorder and environmental homeostasis imbalance in the alveoli. Application researches focus on the treatment strategies of PAP. The existing PAP animal models cannot fully reflect to the development of human PAP, which should be further developed and improved to provide the basis for clinical practice.

Abstract
Non-negative matrix factorization, which decomposes the input non-negative matrix into product of two non-negative matrices, has been widely used in the neuroimaging field due to its flexible interpretability with non-negativity property. Nowadays, especially in the neuroimaging field, it is common to have at least thousands of voxels while the sample size is only hundreds. The non-negative matrix factorization encounters both computational and theoretical challenge with such high-dimensional data, i.e., there is no guarantee for a sparse and part-based representation of data. To this end, we introduce a co-sparse non-negative matrix factorization method to high-dimensional data by simultaneously imposing sparsity in both two decomposed matrices. Instead of adding some sparsity induced penalty such as l 1 norm, the proposed method directly controls the number of non-zero elements, which can avoid the bias issues and thus yield more accurate results. We developed an alternative primal-dual active set algorithm to derive the co-sparse estimator in a computationally efficient way. The simulation studies showed that our method achieved better performance than the state-of-art methods in detecting the basis matrix and recovering signals, especially under the high-dimensional scenario. In empirical experiments with two neuroimaging data, the proposed method successfully detected difference between Alzheimer's patients and normal person in several brain regions, which suggests that our method may be a valuable toolbox for neuroimaging studies.

Abstract
Combinatorial tumor therapy including chemotherapy and photodynamic therapy (PDT) can compensate for the limitations of each other and significantly increase the therapeutic effect. However, considering the differences of water-soluble characteristics between chemotherapeutic drugs and photosensitizers for photodynamic therapy, simply loading these substances into the same cavities of nanocarriers is rather difficult, leading to the reduced drug loading efficiency. Here, we reported a layered and orthogonal assembly of hydrophilic drugs doxorubicin (Dox) and hydrophobic photosensitizers Chlorin e6 (Ce6) for enhancing the effect of synergistic therapeutics. The assembly was based on polydopamine (PDA) modified with β-cyclodextrin (β-CD) through the addition reaction of -HS in HS-β-CD and-C=C in PDA, then DOX and Ce6 were loaded on the PDA and in the hydrophobic cavities of β-CDs respectively with superior drug loading efficiencies (38.8 ± 0.8% and 5.4 ± 0.3% for DOX and Ce6). PDA was hydrolyzed completely under the lysosomal acidic condition, leading to the controlled release of DOX. Under NIR irradiations, DOX-based chemotherapy was successfully integrated with PDA-based photothermal and Ce6-based photodynamic therapy. Tumor specific aptamer AS1411-modified assembly provides ideal antitumor effects in vitro and in vivo with excellent biocompatibility. Collectively, this layered and orthogonal assembly offers a generalizable solution for delivering matters with distinct aqueous solubility would find broad applications not only in drug delivery but also in bio-nanotechnology.

Abstract
Objective: To analyse the quality of life of patients receiving repair of bone defect with folded fibula flap after removal of mandibular ameloblastoma. Methods: The case data of 39 patients with ameloblastoma admitted to the First Affiliated Hospital of Zhengzhou University from August 2013 to April 2016 were retrospectively analysed, including 21 males and 18 females, from 18 to 58 years old. 3D printing and digital technology were used in flap preparation before surgery in all patients. The folded fibular flaps were used to repair mandibular defects and the implants were placed between 6-9 months after surgery. The short form-36 health survey questionnaire (SF-36) and the university of Washington quality of life questionnaire (UW-QOL) were applied to evaluate the quality of life of patients before surgery and at 6 months and 24 months after surgery. The higher the score, the better the condition. SPSS 20.0 was adopted for statistical analysis. Results: The SF-36 survey showed that the mean score of body role before surgery (72.4±11.7) was significantly higher than that at 6 months after surgery (39.6±11.1, t=23.580, P<0.05) or that at 24 months after surgery (59.8±6.4, t=8.358, P<0.001). Compared with the preoperative mean scores of Physical Pain (73.0±11.0), General Health (73.4±10.4) and Health Changes (79.2±3.9) before surgery, the mean scores Physical Pain (53.1±7.7), General Health (53.5±7.5) and Health Changes (63.9±11.7) at 6 months after surgery were decreased significantly respectively (t=13.068, 13.756 and 10.880, respectively, all P<0.05), but the mean scores Physical Pain (78.8±14.0), General Health (80.9±12.6) and Health Changes (84.4±4.6) at 24 months after surgery were increased significantly respectively (t=-2.904, -4.027 and -7.586, respectively, all P<0.05), with significant differences in the mean scores of Physical Pain, General Health and Health Changes between 6 and 24 months after surgery (t=-14.241, -16.490, -14.294, respectively, all P<0.001). The UW-QOL survey showed that the mean scores of chewing, language and taste functions decreased at 6 months after surgery (53.1±6.7, 53.0±7.7 and 62.2±9.9, respectively), but improved at 24 months after surgery (67.9±3.9, 63.9±2.9 and 68.4±11.1, respectively), with statistically significant difference (t=-16.765, -11.675 and 2.498, respectively, all P<0.001). Conclusion: The application of folded fibula flaps to repair bone defects after sugery of mandibular ameloblastoma can better meet the needs of language and chewing functions and improve the quality of life of patients.

Abstract
BACKGROUND Patients with severe COVID-19 are more likely to develop adverse outcomes with a huge medical burden. We aimed to investigate whether a shorter symptom onset to admission time (SOAT) could improve outcomes of COVID-19 patients. METHODS A single-center retrospective study combined with a meta-analysis was performed. The meta-analysis identified studies published between 1 December 2019 and 15 April 2020. Additionally, clinical data of COVID-19 patients diagnosed between January 20 and February 20, 2020, at the First Affiliated Hospital of the University of Science and Technology of China were retrospectively analyzed. SOAT and severity of illness in patients with COVID-19 were used as effect measures. The random-effects model was used to analyze the heterogeneity across studies. Propensity score matching was applied to adjust for confounding factors in the retrospective study. Categorical data were compared using Fisher's exact test. We compared the differences in laboratory characteristic varied times using a two-way nonparametric, Scheirer-Ray-Hare test. RESULTS In a meta-analysis, we found that patients with adverse outcomes had a longer SOAT (I2 = 39%, mean difference 0.88, 95% confidence interval = 0.47-1.30). After adjusting for confounding factors, such as age, complications, and treatment options, the retrospective analysis results also showed that severe patients had longer SOAT (mean difference 1.13 [1.00, 1.27], p = 0.046). Besides, most biochemical marker levels improved as the hospitalization time lengthened without the effect of disease severity or associated treatment (p < 0.001). CONCLUSION Shortening the SOAT may help reduce the possibility of mild patients with COVID-19 progressing to severe illness.

Abstract
Objective: To investigate the expression and phosphorylation level change of adenosine monophosphate activated protein kinase (AMPK) in skeletal muscle of severely scald rats and its roles in skeletal muscle atrophy in severely scalded rats. Methods: The experimental research method was applied. Totally 100 6-week-old male Wistar rats were divided into sham injury group and scald group according to the random number table, with 50 rats in each group. After weighing the body weight, rats in scald group were inflicted with full-thickness scald of 30% total body surface area on the back, and rats in sham injury group were simulated with scald. At 6 h and on 1, 3, 5, and 7 d post injury, 10 rats in each group were taken to measure their body weights and weights of extensor digitorum longus and soleus muscle. At 6 h and on 1, 3, 5, and 7 d post injury, the tibialis anterior muscles were collected, the mRNA expressions of muscle atrophy F-box protein (MAFbx) and muscle-specific RING finger protein 1 (MuRF1) were detected by real-time fluorescent quantitative reverse transcription polymerase chain reaction; the content of adenosine monophosphate (AMP), adenosine diphosphate, and adenosine triphosphate (ATP) were detected by high performance liquid chromatography, and AMP/ATP ratio and energy charge were calculated; the protein expressions of AMPK-α and phosphorylated AMPK-α (p-AMPK-α) were detected by Western blotting, and the p-AMPK-α/AMPK-α ratio was calculated, with sample number of 4 in each time point of each group. Data were statistically analyzed with analysis of variance for factorial design and least significant difference test. Results: The body weights of rats in 2 groups before injury and at each time point post injury were close (P>0.05). At 6 h post injury, the weight of extensor digitorum longus of rats in scald group was (0.107±0.007) g, which was significantly heavier than (0.086±0.0607) g of sham injury group (P<0.01). On 3 d post injury, the weight of extensor digitorum longus of rats in scald group was (0.083±0.016) g, which was significantly lighter than (0.102±0.005) g of sham injury group (P<0.01). The weight of soleus of rats in 2 groups were close at each time point post injury (P>0.05). Compared with those of sham injury group, the mRNA expression of MAFbx in tibialis anterior muscle of rats in scald group was significantly up-regulated at 6 h post injury (P<0.01), and the mRNA expressions of MuRF1 in tibial anterior muscle of rats in scald group were significantly up-regulated at 6 h and on 1 d post injury (P<0.01). At 6 h and on 7 d post injury, compared with those of false injury group, the AMP/ATP ratios of the tibial anterior muscle of rats in scald group were significantly increased (P<0.05 or P<0.01), and energy charges of the tibial anterior muscle of rats in scald group were significantly decreased (P<0.01). At each time point post injury, the protein expressions of AMPK-α of the tibial anterior muscle of rats in 2 groups were close (P>0.05). The p-AMPK-α/AMPK-α ratios of the tibial anterior muscle of rats in scald group at 6 h and on 7 d post injury were significantly higher than those in sham injury group (P<0.05 or P<0.01). Conclusions: The decrease in energy charge and increase in AMP/ATP ratio of skeletal muscle of rats after severe scald activate AMPK. The activation of AMPK in the early stage of injury is consistent with the up-regulation of MAFbx and MuRF1 expressions and down-regulation of skeletal muscle weight. The above-mentioned changes may be one of the molecular mechanisms of skeletal muscle atrophy in rats with severe scald.

Abstract
As an inhibitor of ethylene receptors, 1-methylcyclopropene (1-MCP) can delay the ripening of papaya. However, improper 1-MCP treatment will cause a rubbery texture in papaya. Understanding of the underlying mechanism is still lacking. In the present work, a comparative sRNA analysis was conducted after different 1-MCP treatments and identified a total of 213 miRNAs, of which 44 were known miRNAs and 169 were novel miRNAs in papaya. Comprehensive functional enrichment analysis indicated that plant hormone signal pathways play an important role in fruit ripening. Through the comparative analysis of sRNAs and transcriptome sequencing, a total of 11 miRNAs and 12 target genes were associated with the ethylene and auxin signaling pathways. A total of 1741 target genes of miRNAs were identified by degradome sequencing, and nine miRNAs and eight miRNAs were differentially expressed under the ethylene and auxin signaling pathways, respectively. The network regulation diagram of miRNAs and target genes during fruit ripening was drawn. The expression of 11 miRNAs and 12 target genes was verified by RT-qPCR. The target gene verification showed that cpa-miR390a and cpa-miR396 target CpARF19-like and CpERF RAP2-12-like, respectively, affecting the ethylene and auxin signaling pathways and, therefore, papaya ripening.

Abstract
To explore the feasibility of using the posteromedial thigh flap as an alternative source for oral and maxillofacial reconstruction. During January 2019 to January 2020, twenty-three patients underwent oral and maxillofacial tumor ablation and defect reconstruction with 23 posteromedial thigh flaps were enrolled in the Department of Oral and Maxillofacial Surgery, The First Affiliated Hospital of Zhengzhou University. Thirteen of the patients were male and ten were female, with age of (54.5±9.7) years (33-72 years). The numbers and types of perforators, the dimension of flap and the vascular pedicle length were measured. The outcomes of flaps and donor-site complication were recorded. The patients' satisfaction with donor-site cosmesis were evaluated by the visual analogue scale (VAS). More than one sizable perforators was found in each case and the median number of perforators was 2 (range, 1 to 4), and all of the perforators were musculocutaneous. The pedicle length was (9.8±1.5) cm (range, 7.3 to 13.4 cm). The diameters of artery and the larger vein were 2.0 mm (range, 1.5 to 2.5 mm) and 2.0 mm (range, 1.5 to 3.0 mm), respectively. The dimension of the flaps ranged from 8 cm×6 cm to 12 cm×8 cm, and the donor sites were all closed primarily. All of the flaps were clinically survived, only one patient experienced partial wound dehiscence of donor site 14 days postoperatively and no donor site infection or permanent muscular weakness was reported. The VAS scores of the patients' satisfaction with donor-site cosmesis were all more than 8. The perforators of the posteromedial thigh flap is consistent and the donor-site scar is well concealed, which make the posteromedial thigh flap an excellent option for oral and maxillofacial reconstruction.

Abstract
Objective: To describe the clinical features of liver involvement in children and adolescent with 2019-nCoV infection. Methods: The clinical data of 77 hospitalized cases admitted to the Children's Hospital of Fudan University were collected from January 19 to November 28, 2020. The characteristics and risk factors of abnormal liver chemistries in children with laboratory-confirmed 2019-nCoV infection were analyzed. Results: Of the 77 cases, 44 were male (57.1%) and 33 were female (42.9%), with a median age of 10 years. 27(35.1%) were asymptomatic, 28(36.4%) had mild illness, 22(28.6%)had non-severe pneumonia. Hydroxychloroquine was used in 7 cases. Of the 75 children without underlying diseases, alanine aminotransferase was elevated in 1 case (1.5%, during hydroxychloroquine therapy), aspartate aminotransferase was elevated in 7 cases (10.3%), alkaline phosphatase was elevated in 7 cases (28%), and total bilirubin, direct bilirubin, albumin, international normalized ratio were in normal range. There was no statistical difference between the pneumonia group and the non-pneumonia group in term of liver chemistries (P > 0.05), same as between the elevated erythrocyte sedimentation rate group and the normal group. There was no aggravation of liver injury in the child with biliary atresia. The child with epilepsy showed no abnormal liver chemistries after infection. Conclusion: Children with 2019-nCoV infection had mild clinical symptoms with few cases of liver injury. The abnormal liver chemistries in children with COVID-19 infection may be related to the underlying disease and the use of antiviral drugs.

Abstract
HBV infection plays a crucial role in primary liver cancer development. Also, HBV related liver cancer has higher invasiveness and earlier discovered distant metastasis. HBV-encoded X protein (HBx) exerts various biological functions on liver cancer progression, including proliferation, invasion, and venous metastasis. There is evidence that High-mobility group box 1 (HMGB1) promotes epithelial-mesenchymal transition (EMT) and angiogenesis of tumors, including liver cancer. Therefore, this study investigates whether HMGB1 mediates HBx-induced EMT and angiogenesis in HBV related liver cancer. We collected 76 tumor samples of primary liver cancer patients to analyze the relationship between HMGB1 and portal vein tumor thrombus (PVTT) in HBV related liver cancer. To test the influence of HMGB1 on EMT and angiogenesis, we constructed HBx lentivirus transfected HepG2/Huh7 cell lines and performed invasion assays, tube formation and in vivo metastatic experiments. We evaluated HMGB1 and STAT3/miR-34a/NF-κB pathway in vivo and in vitro by immunoblot, quantitative real-time polymerase chain reaction (qRT-PCR), immunofluorescence and immunohistochemistry analysis. Subsequent RNA interference (RNAi) and luciferase reporter assay were conducted to detect the functional correlation between HMGB1 and STAT3/miR-34a/NF-κB pathway. Our results showed enhanced expression of HMGB1 in HBV related liver cancer, especially with PVTT, while HMGB1 expression was associated with tumor invasion and metastasis. Further experiments indicated that the activation of STAT3 mediated HBx-induced HMGB1, which is involved in EMT and tumor angiogenesis. Besides, HMGB1 expression stimulated by HBx was dependent on the activation of the NF-κB signaling pathway, which was inhibited by miR-34a, while STAT3 suppressed the expression of miR-34a. Moreover, extracellular HMGB1 induced the IL-6/STAT3/miR-34a axis activation, which indicated a reciprocal relationship between HMGB1 and miR-34a. Collectively, our study provided evidence to reveal that HBx-mediated high expression of HMGB1 accounted for EMT and tumor angiogenesis in HBV related liver cancer, and HMGB1 may be a potential target for predicting venous metastasis.

Abstract
Treatment with 1-methylcyclopropylene (1-MCP) is an effective technique to preserve fruits, but inappropriate treatment with 1-MCP causes a ripening disorder (rubbery texture) in papaya fruit. In this study, a combined metabolomic and transcriptomic analysis was conducted to reveal the possible mechanism of the ripening disorder caused by unsuitable 1-MCP in papaya. A total of 203 differential accumulated metabolites (DAMs) were identified in the metabolome analysis. Only 24 DAMs were identified in the control (CK) vs. the 1-MCP 2 h group, and they were primarily flavonoids. Ninety and 89 DAMs were identified in the CK vs. 1-MCP 16 h and 1-MCP 2 h vs. 1-MCP 16 h groups, respectively, indicating that long-term 1-MCP treatment severely altered the metabolites during fruit ripening. 1-MCP 16 h treatment severely reduced the number of metabolites, which primarily consisted of flavonoids, lipids, phenolic acids, alkaloids, and organic acids. An integrated analysis of RNA-Seq and metabolomics showed that various energy metabolites for the tricarboxylic acid cycle were reduced by long-term treatment with 1-MCP, and the glycolic acid cycle was the most significantly affected, as well as the phenylpropane pathway. These results provide valuable information for fruit quality control and new insight into the ripening disorder caused by unsuitable treatment with 1-MCP in papaya.

Abstract
BACKGROUND Spine surgery causes severe pain and can be associated with significant opioid utilization; however, the evidence for opioid-sparing analgesic techniques such as erector spinae plane (ESP) block from controlled studies is limited. We aimed to investigate the analgesic effects of ESP block in lumbar laminoplasty. METHODS In this prospective, double-blind, controlled single-center trial, 62 consecutive elective lumbar laminoplasty patients were randomized into either a control group (Group G, N=32) or a treatment group (Group E, N=30). Group G received general anesthesia and multimodal analgesia, similar to group E, while Group E received additional bilateral ESP block after induction of general anesthesia. The primary outcome was postoperative pain scores for the first 48 h after surgery, and the secondary outcomes analyzed included intraoperative anesthetic usage, perioperative analgesic consumption, return of bowel function and satisfaction for acute pain management indicated by overall benefit of analgesia score (OBAS). RESULTS Significant differences in pain scores over time were found between the two groups (P=0.010), with Group E patients having significantly lower pain scores than Group G during the first six hours (P=0.000). The opioid consumption in Group G was significantly higher than in Group E both intraoperatively (P=0.000) and postoperatively (P=0.0005). Group E patients had lower intraoperative sevoflurane requirement, improved satisfaction with pain management, and earlier return of bowel function than Group G patients. CONCLUSION ESP block is effective in reducing postoperative pain scores and lowering opioid utilization (both intraoperatively and postoperatively), resulting in improved patient satisfaction for pain management in lumbar laminoplasty.

Abstract
Abstract
BackgroundIn complex disease studies, genome-wide association study (GWAS) has been successfully used for identifying associated genetic risk loci. In fact, only a small fraction of the apparent heritability can be explained by common variants. Because research efforts have largely focused on common genetic variants, the missing heritability could be mostly due to rare genetic variants. Substantial research efforts have been devoted to developing software for genotype imputation and designing variant binning strategies and statistical methods for rare variant association testing of datasets on GWAS chips. However, few systematic pipelines have been proposed to identify rare disease-related genes. ResultsWe present EGRVA, an Effective Gene-based Rare Variant Association analysis pipeline for genotype imputation, quality control, gene-based functional annotation, statistical analysis, and bioinformatics analysis of identified genes. As a complementary pipeline for rare variant analysis on GWAS chips, EGRVA is relatively straightforward and cost-efficient. Furthermore, we tested the EGRVA pipeline with the preterm birth (PTB) dataset from the GPN-PBR. We focused on the 6 genes identified by EGRVA: FLG, HRNR, PMS1, ATM, OR2AG1 and SLC22A25. We also explored the underlying biological interpretation of these potentially significant genes. ConclusionsAs a complementary pipeline for rare variant analysis on GWAS chips, EGRVA is relatively straightforward and costefficient. The application of the pipeline will contribute to the support of rare variants to explain the missing heritability by effectively discovering genes related to disease.

Abstract
BACKGROUND Disparities in multiple myeloma (MM) prognosis based on sociodemographic factors may exist. We investigated whether education level at diagnosis influenced Chinese MM patient outcomes. METHODS We performed a multicenter retrospective analysis of data from 773 MM patients across 9 centers in China from 2006 to 2019. Sociodemographic and clinical factors at diagnosis and treatment regimens were recorded, and univariate and multivariate analyses were performed. RESULTS Overall, 69.2% of patients had low education levels. Patients with low education levels differed from those with high education levels in that they were more likely to be older, and a higher proportion lived in rural areas, were unemployed, had lower annual incomes and lacked insurance. Additionally, compared to patients with high education levels, patients with low education levels had a higher proportion of international staging system (ISS) stage III classification and elevated lactate dehydrogenase (LDH) levels and underwent transplantation less often. Patients with high education levels had a median progression-free survival (PFS) of 67.50 (95% confidence interval (CI): 51.66-83.39) months, which was better than that of patients with low education levels (30.60 months, 95% CI: 27.38-33.82, p < 0.001). Similarly, patients with high education levels had a median overall survival (OS) of 122.27 (95% CI: 117.05-127.49) months, which was also better than that of patients with low education levels (58.83 months, 95% CI: 48.87-62.79, p < 0.001). In the multivariable analysis, patients with high education levels had lower relapse rates and higher survival rates than did those with low education level in terms of PFS and OS (hazard ratio (HR) = 0.50 [95% CI: 0.34-0.72], p < 0.001; HR = 0.32 [0.19-0.56], p < 0.001, respectively). CONCLUSIONS Low education levels may independently predict poor survival in MM patients in China.

Abstract
OBJECTIVE The association of serum calcium with metabolic syndrome in colorectal cancer (CRC) is largely unknown. This study investigated the relationship between serum calcium and patients' clinical characteristics, as well as metabolic parameters in CRC patients. METHODS CRC patients in Peking University People's Hospital from June 2015 to December 2018 were included; serum calcium, HDL (high-density lipoprotein), LDL (low-density lipoprotein), TC (total cholesterol), TG (triglyceride), FPG (fasting plasma glucose) and albumin were detected. An unpaired t test and covariance analysis were conducted to determine the difference of serum calcium in different groups. Correlation analyses (simple and partial) were carried out to evaluate the association of serum calcium with metabolic parameters. RESULTS Two hundred and fifteen patients were recruited in the study. CRC patients with distal lesions had higher levels of total and corrected calcium than the proximal lesion group by adjusting for confounders, and patients with small tumor size, as well as with a history of diabetes, exhibited higher total calcium than their counterparts. Significant associations of total calcium with serum glucose and lipids were observed in CRC patients, and the correlation between total calcium and serum lipids was still significant by adjusting for confounders. Corrected calcium showed a significant correlation with LDL and TC but not with FPG, TG or HDL. CONCLUSIONS Serum calcium, especially total calcium, might be more sensitive than FPG and lipids for metabolic syndrome in CRC patients.

Abstract
PURPOSE The present study was designed to determine the relationships between sarcopenia and diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (T2DM) and diabetic foot disease (DFD) respectively. PATIENTS AND METHODS A total of 1104 patients with T2DM and 257 patients with DFD were included in the study, which was designed as a cross-sectional study. Body composition was assessed using dual-energy X-ray-absorptiometry (DXA). The diagnosis of sarcopenia was based on the Baumgartner criteria. DPN was assessed by Neuropathy symptom score (NSS) and Neuropathy disability score (NDS), and the severity of neuropathy was divided into non-neuropathy symptom (NS), Mild NS, Moderate NS and Severe NS according to NSS. Logistic regression analyses were carried out to determine the relations of sarcopenia and DPN in patients with T2DM and NSS in patients with DFD, respectively. RESULTS The prevalence of DPN was 80.0% in T2DM patients with sarcopenia and 70.3% in non-sarcopenia patients (P=0.007). Logistic regression analyses showed DPN was one of the independent risk factors for sarcopenia in T2DM patients (OR 1.564 [95% CI: 1.004, 2.435], P=0.048). The prevalence of DPN had no statistical significance in DFD patients with or without sarcopenia. However, the NSS of DFD patients with sarcopenia was higher than that of non-sarcopenia patients. In the multivariate logistic regression analysis, NSS was determined to be associated with sarcopenia in DFD patients (OR 1.387[95% CI: 1.074, 1.789], P=0.012). The appendicular lean mass (ALM) of DFD patients without NS was higher than patients with mild, moderate and severe NS (20.71±2.73 vs 16.57±3.62 vs 17.99±3.54 vs 17.23±3.29 Kg, P=0.028). CONCLUSION DPN is an independent risk factor for sarcopenia in patients with T2DM and NSS is also independently correlated with sarcopenia in patients with DFD, with the latter being more obvious with the aggravation of neurological symptoms in DFD patients.

Abstract
In this work, to achieve both clean energy production and carbon emission reduction, a united conversion to couple CO2 mineralization with thermochemical hydrogen production is proposed. Natural magnesium silicate minerals are used to fix CO2 in the form of carbonate minerals, whereas H2O is dissociated to produce H2 in the thermochemical cycle. The integration provides a new solution to the challenges of the high energy consumption and poor economic value of conventional CO2 mineralization processes, and the technical feasibility has been proven. Moreover, the energy economy and CO2 conversion capacity were investigated. Hydrolyzation and carbonation experiments were performed in a homemade reactor, and it was found that an optimal MgI2 hydrolyzation rate of 75% could be achieved without alkali consumption. A detailed simulation of the whole system was also developed. The optimal energy conversion efficiency of the cycle reached 47.6%, which is higher than most of the published theoretical energy efficiency values for sulfur-iodine thermochemical cycles. A modified calculation of the net energy requirement for CO2 mineralization was carried out. Finally, a comparison and an evaluation of the energy efficiencies were made based on the calculation. In the optimal case, the modified net energy requirement is 1.4 MJ/kg CO2, which means that this method is competitive compared to those of previous works.

Abstract
Arsenic (As) contamination in subsoil and groundwater is a big problem, especially in many South-East Asian countries. As a staple crop growing under flooded condition in these areas, rice (Oryza sativa L.) becomes a big threat to human health through the food chain since As is highly accumulated in grains. Thus, reducing As accumulation in rice through molecular breeding and identification of rice varieties with low As content are the pressing issues. However, the current understanding on the molecular mechanism of As stress response is still limited for rice. In this study, we performed a comprehensive search for the As-responsive small RNAs (sRNAs) of rice. Briefly, 4,762 and 18,152 sRNAs were identified to be highly activated under As stress in roots and shoots respectively, while 14,603 and 8,308 sRNAs were intensively repressed by As treatment in roots and shoots, respectively. A number of the As-responsive sRNAs found their loci on tRNAs, rRNAs or long non-coding RNAs (lncRNAs). Interestingly, these loci preferentially distributed on the 5' halves of the tRNA, rRNA or lncRNA precursors. Among the above-identified As-responsive sRNAs, 252 Argonaute 1 (AGO1)-enriched sRNAs were extracted for target identification, resulting in 200 pairs of sRNA-protein-coding target interactions. Many targets are functionally involved in the development, stress response, reproduction, or lipid metabolism. Additionally, 56 lncRNAs were discovered to be targeted by nine AGO1-enriched sRNAs, indicating the potential involvement of these lncRNAs in As signaling. Taken together, our results could expand the understanding on the non-coding RNA-mediated As stress response in rice.

Abstract
Physalis angulata L., a member of the family Solanaceae, is widely used as the folk medicine in various countries. Continuous research efforts are devoted to the discovery of the effective medicinal ingredients from Physalis angulata. However, due to the limited resources of genome and transcriptome sequencing data, only a few studies have been performed at the gene regulatory level. In this study, the transcriptomes of five organs (roots, stems, leaves, flowers and fruits) of Physalis angulata were reported. Based on the transcriptome assembly containing 196,117 unique transcripts, a total of 17,556 SSRs (simple sequence repeats) were identified, which could be useful RNA-based barcoding for discrimination of the plants closely relative to Physalis angulata. Additionally, 24 transcripts were discovered to be the potential microRNA (miRNA) precursors which encode a total of 31 distinct mature miRNAs. Some of these precursors showed organ-specific expression patterns. Target prediction revealed 116 miRNA-target pairs, involving 31 miRNAs and 83 target transcripts in Physalis angulata. Taken together, our results could serve as the data resource for in-depth studies on the molecular regulatory mechanisms related to the production of medicinal ingredients in Physalis angulata.
