Abstract
Influenza is a contagious respiratory disease caused by influenza viruses, and the burden of severe disease is commonly seen in high risk populations. Influenza vaccination is an effective way to prevent influenza and its complications, especially for high risk populations. Although some countries have included influenza vaccine in their national immunization programs, influenza vaccination rates remain low globally in high risk populations. The influenza vaccine in China is still a non-immunization program vaccine that is voluntarily vaccinated at its own expense, and the influenza vaccine immunization strategy is different across the country. There is still a gap between the vaccination rate of the influenza vaccine and that of developed countries. It is an urgent problem to further optimize the whole population immunization strategy of influenza vaccine in China, strengthen the publicity of the whole population immunization strategy of influenza vaccine, and reduce the disease burden of influenza in China.

Abstract
Several studies have indicated that circular RNAs (circRNAs) play vital roles in the progression of various diseases, including bladder cancer (BCa). However, the underlying mechanisms by which circRNAs drive BCa malignancy remain unclear. In this study, we identified a novel circRNA, circPSMA7 (circbaseID:has_circ_0003456), showing increased expression in BCa cell lines and tissues, by integrating the reported information with circRNA-seq and qRT-PCR. We revealed that circPSMA7 is associated with a higher tumor grade and stage in BCa. M6A modification was identified in circPSMA7, and IGF2BP3 recognized this modification and stabilized circPSMA7, subsequently increasing the circPSMA7 expression. In vitro and in vivo experiments showed that circPSMA7 promoted BCa proliferation and metastasis by regulating the cell cycle and EMT processes. CircPSMA7 acted as a sponge for miR-128-3p, which showed antitumor effects in BCa cell lines, increasing the expression of MAPK1. The tumor proliferation and metastasis suppression induced by silencing circPSMA7 could be partly reversed by miR-128-3p inhibition. Thus, the METTL3/IGF2BP3/circPSMA7/miR-128-3p/MAPK1 axis plays a critical role in BCa progression. Furthermore, circPSMA7 may be a potential diagnostic biomarker and novel therapeutic target for patients with BCa.

Abstract
In order to alleviate the resource and environmental problems caused by plastic film materials, the development of biodegradable cellulose-based films is crucial. Inspired by the strengthening mechanism of cellulose-lignin network from wood, carboxylated lignin (CL) was isolated using maleic acid (MA) pretreatment catalyzed by metal chlorides. Compared with pure MA, the presence of metal ions yielded CL with high carboxyl content (0.34 mmol/g), small size and good dispersibility. CL was then composited with CNF to prepare various CL/cellulose nanofibrils (CNF) composite films. When the addition of ferric chloride was 0.3 mmol/g maleic acid, the corresponding composite films exhibited highest tensile strength (180.0 MPa), Young's modulus (13.0 GPa) and excellent ultraviolet blocking rate (97.0 %). Meanwhile, the interaction forces measured by atomic force microscope showed that the binding between CNF and various CLs (276-406 nN) was higher than that between pure CNFs (202 nN), verifying that CL enhanced the mechanical properties of composite films. In summary, this work constructs a super-strong network between CL and CNF synergistically mediated by metal ion crosslinking and hydrogen bonding, which can be a promising alternative to replace conventional plastics in multiple areas.

Abstract
This article uses the "behavioural and social drivers of vaccination" model released by the World Health Organization (WHO) in 2022 to analyze influenza vaccine policy documents issued by the state and governments. This indicates that the current influenza vaccination policy in China has paid some attention to "publicity and mobilization", but it still pays insufficient attention to "vaccination convenience". It is recommended to continue to strengthen publicity and mobilization, explore ways to improve the convenience of vaccination, formulate corresponding plans to improve the convenience of vaccination, scientifically set vaccination rate targets, and encourage areas with conditions to carry out free vaccination projects for key populations.

Abstract
OBJECTIVE The objective of this study was to investigate the role of echocardiographic parameters in diagnosing bronchopulmonary dysplasia (BPD) in preterm infants. PATIENTS AND METHODS Ninety preterm infants with a gestational age of less than 32 weeks and a weight less than 1.5 kg, admitted to the neonatal intensive care unit of the hospital between January 2020 and January 2021, were selected for the study. The study subjects were divided into two groups: a BPD group (54 cases, observation group) and a non-BPD group (36 cases, control group). The correlation between tricuspid regurgitation (TR) velocity and BPD was investigated by detecting the cardiac function of preterm infants in both groups using a color Doppler ultrasound diagnostic instrument and analyzing the cardiac ultrasound results. The early prediction efficiency of TR velocity (m/s) for BPD was evaluated using the receiver operator characteristic (ROC) curve. RESULTS The incidence of patent ductus arteriosus (PDA) and pulmonary hypertension (PH) in the observation group was significantly higher than that in the control group. The levels of left ventricular ejection fraction (LVEF) and left ventricular shorting fraction (LVFS) were significantly lower than those in the control group (p < 0.05). The incidence of patent foramen ovale (PFO), atrial septal defect (ASD), and ventricular septal defect (VSD) in the observation group were not significantly different from the control group (p > 0.05). The proportion of tricuspid regurgitation in the observation group was significantly higher than that in the control group, and the TR velocity was significantly higher than that in the control group. The Spearman correlation analysis showed that TR velocity (m/s) was positively correlated to BPD severity (r = 0.379, p < 0.05). The area under the curve (AUC) for predicting BPD with TR velocity was 0.735. The sensitivity and specificity were 88.0% and 62.6%, respectively, when the TR velocity was 1.45 m/s. CONCLUSIONS Echocardiography is useful for understanding the degree of impaired cardiac function in preterm infants and for early detection of PH, which may reduce the mortality rate to a certain extent. The risk of BPD is significantly increased when TR velocity is higher than 1.45 m/s.

Abstract
Vaccination is the most cost-effective measure to prevent infectious diseases in both children and adults. At present, the global burden of infectious diseases in adults is still heavy. With the continuous development and improvement of vaccines, vaccination has shown great potential to prevent infectious diseases, further reduce the morbidity and mortality of infectious diseases in adults and improve people's life quality. This article summarizes the current status of adult immunization, immunization strategies of representative countries, different adult vaccination strategies, and the advantages and challenges of adult immunization to provide reference for further exploring adult immunization strategies and improving adult vaccination recommendations. More attention should be paid to the immunization strategies for different adult populations, and effective measures should be taken to improve the vaccination coverage for the better protection of people's life and health.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) induces B and T cell responses, contributing to virus neutralization. In a cohort of 2,911 young adults, we identified 65 individuals who had an asymptomatic or mildly symptomatic SARS-CoV-2 infection and characterized their humoral and T cell responses to the Spike (S), Nucleocapsid (N) and Membrane (M) proteins. We found that previous infection induced CD4 T cells that vigorously responded to pools of peptides derived from the S and N proteins. By using statistical and machine learning models, we observed that the T cell response highly correlated with a compound titer of antibodies against the Receptor Binding Domain (RBD), S and N. However, while serum antibodies decayed over time, the cellular phenotype of these individuals remained stable over four months. Our computational analysis demonstrates that in young adults, asymptomatic and paucisymptomatic SARS-CoV-2 infections can induce robust and long-lasting CD4 T cell responses that exhibit slower decays than antibody titers. These observations imply that next-generation COVID-19 vaccines should be designed to induce stronger cellular responses to sustain the generation of potent neutralizing antibodies.

Abstract
This article reviews the relevant studies on the efficacy and safety of influenza, pneumococcal and COVID-19 vaccination among tumor patients worldwide in recent years. By combing and analyzing the retrieved literature, the results show that influenza and pneumococcal vaccination can significantly reduce the morbidity and hospitalization rate of infectious diseases in tumor patients, reduce the risk of cardiovascular events and death, and significantly improve survival prognosis. COVID-19 vaccination can also protect tumor patients, especially those who have completed full dose vaccination. Authoritative guidelines and consensuses worldwide all recommend that tumor patients receive influenza, pneumococcal and COVID-19 vaccines. We should carry out relevant researches, as well as take effective measures to strengthen patient education, so that tumor patients can fully experience the health protection brought by the vaccine to this specific group.

Abstract
Objective: To explore the effects of exposure of pregnant rats to radio frequency electromagnetic field on the ultrastructure of hippocampus and the levels of obesity related protein (FTO) and nerve growth factor (NGF) in offspring rats. Methods: In September 2019, 36 healthy 7-week-old Wistar rats were selected, including 24 female rats (150-200 g) and 12 male rats (200-250 g) . The male and female mice were mated in the cage at 2: 1 ratio at 18: 00 every night. The smear results showed that the sperm was positive and the mating was successful. The day was regarded as the 0 day of pregnancy. Pregnant rats were randomly divided into 3 experimental groups and 3 control groups, with 4 rats in each group. The experimental group was exposed to 1 800 MHz, Wi-Fi and 1 800 MHz+Wi-Fi respectively, and the three control groups were exposed to virtual exposure. 12 hours a day for 21 days in three batches. After the end of exposure, the offspring of each group were raised for 7 weeks. The ultrastructural changes of the hippocampus were observed by transmission electron microscopy, the FTO level in the hippocampus was determined by Western blot, and the NGF level in the brain tissue was determined by ELISA. Results: Transmission electron microscopy showed that the nuclei of hippocampal tissue of female and male rats in the 1800 MHz group were slightly contracted, the cytoplasm was slightly edema, and the nuclei of male rats were obviously irregular. In the offspring of male and female rats in the Wi-Fi group, the nucleus of hippocampal tissue contracted seriously, the cell membrane was irregular, and the cytoplasm appeared obvious edema. In the 1800 MHz+Wi-Fi group, the nuclei of hippocampal tissue of both male and female offspring rats were severely contracted, the nuclear membrane was irregular, and the cytoplasm was severely edema. there was no significant difference in FTO level among the groups (P>0.05) . Compared with other groups, NGF content in hippocampus of offspring rats in the 1800 MHz+Wi-Fi group was significantly higher (P<0.05) . Conclusion: Exposure to radio frequency electromagnetic fields will damage the morphological structure of hippocampal tissue of offspring and stimulate the increase of NGF expression in the hippocampus.

Abstract
A comprehensive review of the research of the effectiveness of influenza vaccine and 23 valent pneumococcal polysaccharide vaccine (PPV23) in patients with chronic obstructive pulmonary disease (COPD) both at home and abroad in recent years showed that influenza vaccine and PPV23 immunization can significantly reduce the risk for influenza and pneumonia in COPD patients, and reduce the acute exacerbation of disease and related hospitalization. In particular, the influenza vaccination can also reduce the risk for ischemic heart disease, acute coronary syndrome, ventricular arrhythmia, lung cancer, dementia and death in the patients, and the immunization of both vaccines has a more significant protective effect. It is recommended by authoritative guidelines both at home and abroad that COPD patients can receive influenza vaccine and PPV23. At present, the coverage of domestic influenza and pneumococcal vaccines are low, and there are less studies in the applications of both vaccines in patients with COPD. Effective measures should be taken to strengthen the health education and increase the vaccination coverage. Additionally, the clinical research of influenza vaccine and PPV23 for COPD patients, especially the analysis on clinical benefit of immunization of both vaccines, should be further strengthened to effectively improve the survival and prognosis of COPD patients.

Abstract
The aim of the current systematic review was to summarize and to evaluate the available information on the effectiveness of oral exercise in improving the masticatory function of people ≥18 y. Electronic databases (Medline, Embase, CENTRAL) and gray literatures were searched (up to December 2020) for relevant randomized and nonrandomized controlled clinical trials. Two reviewers independently conducted the study selection, data extraction, and quality assessments. Meta-analysis was conducted for the comparison of bite force and masticatory performance using mean difference (MD) and standardized mean difference (SMD), respectively. GRADE (Grading of Recommendations Assessment, Development, and Evaluation) assessment was adopted for collective grading of the overall body of evidence. Of the 1,576 records identified, 18 studies (21 articles) were included in the analysis. Results of meta-analysis indicated that oral exercise could significantly improve the mean bite force of the participants (parallel comparison: MD, 41.2; 95% CI, 11.6-70.7, P = 0.006; longitudinal comparison: MD, 126.5; 95% CI, 105.2-144.9, P < 0.001). However, the improvement in masticatory performance was not significant (parallel comparison: SMD, 0.11; 95% CI, -0.20 to 0.42, P = 0.48; longitudinal comparison: SMD, 0.4; 95% CI, -0.11 to 0.91, P = 0.13). Results of meta-regression showed that greater improvements in bite force can be achieved among younger adults and with more intensive exercise. Chewing exercise is the most effective oral exercise, followed by clenching exercise, while simple oral exercise may not have a significant effect. Based on the results of the meta-analysis and GRADE assessment, a weak recommendation for people with declined masticatory function to practice oral exercise is made.

Abstract
Abstract
Background
Gene mutations have been implicated in DCM. However, due to the difficulty of clinical genetic diagnosis, more causal genes potentially related to DCM remain to be discovered.
Methods
We screened for gene mutations in more than 400 cases from families with hereditary cardiovascular disease using whole-exome sequencing. Then we validated biological functions of CHMP4C mutations in zebrafish models. To further assess the mechanism of CHMP4C mutations, we evaluated the potential signaling pathway in the cells.
Results
We identification of CHMP4C variants that segregated with DCM variants in four families from a total of 411 families via whole-exome sequencing. We further validate the function of CHMP4C in heart function in zebrafish models and found that over-expression of CHMP4C variants in zebrafish resulted in cardiac malformation, pericardial edema and increased heart rate, consistent with CHMP4C mutation-associated findings in DCM patients. Furthermore, we found that mutations in CHMP4C impaired autophagy and activated apoptosis in HEK293T cells, suggesting that the molecular mechanism of CHMP4C is involved in heart development.
Conclusions
CHMP4C is a novel candidate gene for DCM and may play a critical role in cardiac development by regulating autophagy.

Abstract
Abstract
Background
Non-invasive left ventricular (LV) pressure-strain loops (PSLs) which generated by combining LV longitudinal strain with brachial artery blood pressure, provide a novel method of quantifying global and segmental myocardial work (MW) indices with potential advantages over conventional echocardiographic strain which is load-dependent. The method has been introduced in echocardiographic software recently, making MW calculations more effectively and rapidly. The aim was to evaluate the role of non-invasive MW indices derived from LV PSLs in the prediction of cardiac resynchronization therapy (CRT) response.
Methods
106 heart failure (HF) patients scheduled for CRT were included for MW analysis. Global and segmental (septal and lateral at the mid-ventricular level) MW indices were accessed before CRT. Response to CRT was defined as ≥15% reduction in LV end-systolic volume at 6-month follow-up in comparison with baseline value.
Results
CRT response was observed in 78 (74%) patients. At baseline, global work index (GWI) and global constructive work (GCW) were significant higher in CRT responders than in non-responders (both P<0.05). Besides, responders exhibited a significantly higher Mid Lateral MW and Mid Lateral constructive work (CW) (both P<0.001) but a significantly lower Mid Septal MW and Mid Septal myocardial work efficiency (MWE), as well as a significantly higher Mid Septal wasted work (WW) than non-responders (all P<0.01). Baseline Mid Septal MWE (OR 0.975, 95% CI 0.959–0.990, P=0.002) and Mid Lateral MW (OR 1.003, 95% CI 1.002–1.004, P<0.001) were identified as independent predictors of CRT response in multivariate regression analysis. Mid Septal MWE ≤42% combined with Mid Lateral MW ≥740 mm Hg% predicted CRT response with the optimal sensitivity of 79% and specificity of 82% (AUC = 0.830, P<0.001).
Conclusion
Mid Septal MWE and Mid Lateral MW can successfully predict response to CRT, and their combination can further improve the prediction accuracy. Assessment of MW indices before CRT could identify the marked misbalance in LV myocardial work distribution and has the potential to be widely used as a reliable complementary tool for guiding patient selection in clinical practice.

Abstract
Iron homeostasis is essential for maintaining cellular function in a wide range of cell types. However, whether iron affects the thermogenic properties of adipocytes is currently unknown. Using integrative analyses of multi-omics data, transferrin receptor 1 (Tfr1) is identified as a candidate for regulating thermogenesis in beige adipocytes. Furthermore, it is shown that mice lacking Tfr1 specifically in adipocytes have impaired thermogenesis, increased insulin resistance, and low-grade inflammation accompanied by iron deficiency and mitochondrial dysfunction. Mechanistically, the cold treatment in beige adipocytes selectively stabilizes hypoxia-inducible factor 1-alpha (HIF1α), upregulating the Tfr1 gene, and thermogenic adipocyte-specific Hif1α deletion reduces thermogenic gene expression in beige fat without altering core body temperature. Notably, Tfr1 deficiency in interscapular brown adipose tissue (iBAT) leads to the transdifferentiation of brown preadipocytes into white adipocytes and muscle cells; in contrast, long-term exposure to a low-iron diet fails to phenocopy the transdifferentiation effect found in Tfr1-deficient mice. Moreover, mice lacking transmembrane serine protease 6 (Tmprss6) develop iron deficiency in both inguinal white adipose tissue (iWAT) and iBAT, and have impaired cold-induced beige adipocyte formation and brown fat thermogenesis. Taken together, these findings indicate that Tfr1 plays an essential role in thermogenic adipocytes via both iron-dependent and iron-independent mechanisms.

Abstract
BACKGROUND Cleft palate results from the defective palatal fusion of the medial-edge epithelium after cells undergo epithelial-mesenchymal transition, a process that involves regulation by microRNAs (miRNAs). However, in palatal shelf fusion, miRNA regulation by long non-coding RNAs (lncRNAs) when acting as competing endogenous RNAs (ceRNAs) or miRNA sponges, remains unclear. METHODS We systematically analyzed the correlation between lncRNAs, miRNAs, and mRNAs from RNA sequencing profiling in embryonic gestation day 14.5 (E14.5) mouse embryos from control (n=3) and all-trans retinoic acid (ATRA)-treated (n=3) mice. We then constructed a lncRNA-associated ceRNA network. The expression profiles of mRNA, lncRNA, and miRNA were verified by quantitative polymerase chain reaction (qPCR). RESULTS In total, 18 aberrantly expressed miRNAs, 861 mRNAs, and 583 lncRNAs were identified from palate samples of control and ATRA-treated samples. Bioinformatics data and integrative analysis identified 69 lncRNAs, 18 miRNAs, and 78 mRNAs that were aberrantly expressed, and a ceRNA network was then constructed. Finally, we identified a NONMMUT004850.2/NONMMUT024276.2-miR-741-3p/miR-465b-5p-Prkar1α ceRNA network associated with palatal shelf fusion at E14.5. The qPCR results showed that NONMMUT004850.2 (P=5E-05), NONMMUT024276.2 (P=0.0012), and Prkar1α (P=3E-05) were up-regulated, whereas miR-741-3p (P=0.006) and miR-465b-5p (P=1E-04) were down-regulated in ATRA-treated mice compared to the control samples. The qPCR results were in concordance with the RNA sequencing profiling. CONCLUSIONS Our study demonstrated that NONMMUT004850.2/NONMMUT024276.2-miR-741-3p/miR-465b-5p-Prkar1α could potentially serve as an important regulatory mechanism of palatal fusion in the development of the cleft palate.

Abstract
Methylenetetrahydrofolate reductase (MTHFR) polymorphisms are thought to be involved in the development of cleft lip with or without cleft palate (NSCL/P), but published results are contradictory. We therefore designed an updated meta-analysis to pool eligible studies and to evaluate further the possible relations between MTHFR polymorphisms (c.677C>T and c.1298A>C) and susceptibility to NSCL/P. A comprehensive search based on PubMed, Medline, Web of Science, and Embase databases was made up to February 2018. Twenty-three case-control and 10 case-parent trio studies (including 1149 cases and 1161 controls) were retrieved. Odds ratio (OR) with 95% CI were used to estimate the pooled strength of association under different genetic models. The Q test and I2 test were used to estimate heterogeneity among studies, the quality of which was assessed using the Newcastle-Ottawa scale. In the MTHFR c.677C>T polymorphism group, there were significant overall results for the recessive (OR 1.231, 95%CI 1.092 to 1.387) and homozygote (OR 1.252, 95%CI 1.078 to 1.456) models. Subgroup analysis by subjects and ethnicity identified only associations in European mothers for the recessive model and the homozygote model. For the c.1298A>C group, there were no significant results for either European or Asian patients for all genetic models. The MTHFR c.677C>T polymorphism might increase susceptibility to NSCL/P in European mothers, but was negatively associated in Asian patients, and the MTHFR c.1298A>C polymorphism is not involved in the development of NSCL/P in either European or Asian patients.

Abstract
Abstract
Background
The etiology of bicuspid aortic valve disease (BAVD) is still unclear. Recent studies have demonstrated elevated prevalence of genetic defects in BAV patients with root phenotype, which includes aortic regurgitation and root-predominant dilatation.
Purpose
The present study intended to illustrate the feature of genetic defects among early-onset BAV patients with isolated severe aortic regurgitation.
Methods
From June 2015 to December 2017, whole exome sequencing was performed upon 27 BAVD patients with isolated severe aortic regurgitation under 45 years in our institution. Patients were categorized into right-left (R-L, n=16) and non-RL (n=11) cusp fusion types, and those with complex cardiac defects were excluded from the present study.
Results
Among 27 patients with a median age of 30.5 (18–44) years, only one was female with a rare left-non-coronary cusp fusion type. The prevalence of root phenotype was markedly higher in RL patients (56.3% vs 9.1%, p=0.018). In RL patients, the numbers of rare genetic variants (RGVs) were 15 in extracellular matrix genes, 8 in TGF-β signaling pathway genes, 2 in smooth muscle cell contraction apparatus genes, and 3 in familiar BAV related genes. In non-RL patients, the number of RGVs were 15, 3, 4, and 5, respectively. On the other hand, the number of RGVs in above gene clusters were 9, 6, 3, 2 in patients with a root phenotype, and 21, 5, 3, 6 in those without. Eight recurrent genetic variants were identified in 6 genes (see Table). An interesting observation was that ADAMTS2 variants were exclusively found among non-RL patients without root phenotype, as FBN2 variants among RL patients with root phenoype.

Conclusion
Recurrent genetic variants could be identified in a cohort of early-onset BAVD patients with isolated severe aortic regurgitation and staggering male predominance. The incidence and clinical relevance of these variants should be validated in an extended real-world BAV cohort.

Abstract
Abstract
Objective
A new technique has been devised to treat mitral regurgitation (MR) through the transapical route by replicating the edge-to-edge repair surgery. This system encompasses an easy-to-use leaflet clamp and a smaller-sized delivery system (14F–16F). We aimed to evaluate the effectiveness of this device in a porcine model of acute MR.
Methods
Acute MR was induced in 36 anesthetized porcine subjects by severing the major chordae supporting the corresponding segment of the leaflet. This device was then transapically implanted on the prolapsing segment under 3D epicardial echocardiographic guidance. All of the animals were killed 30 days after the procedure to verify the proper location of the implanted devices.
Results
Cutting the major chordae induced an eccentric MR jet (MR grade: 3+, 27.8%/4+, 72.2%) in all of the animals. Every single pig was then successfully implanted with one clamp. The duration of catheterization ranged from 18 to 40 minutes. Overt MR reduction was observed following the procedure through echocardiography; residual MR was mild in 8 cases, trivial in 19 cases, and absent in 9 cases. In terms of hemodynamic parameters, the mean and maximum mitral valve pressure gradients were increased significantly (p<0.01), but these values were less than 4 mmHg in all of the cases. Autopsy demonstrated that all but one device were precisely placed to clip the prolapsing segment of the mitral valve, and there was no evidence of thrombosis, thromboembolism or impairment of the cardiac structure.

Conclusions
Transapical implantation of the novel mitral valve repair device is effective and safe in reducing acutely induced MR in pigs; thus, suggesting that it has great potential for clinical benefit in patients with MR.

Abstract
Three-dimensional (3D) bioprinting allows embedding of cells within a bioink, creating cell-based 3D structures to promote tissue regeneration and repair. The bioink should be biocompatible with the cells and its effect on cell behavior should be determined. Alginate-gelatin (Alg-Gel) blends with mouse planta dermis (PD) induced epidermal progenitors for sweat gland regeneration, confirming the role of 3D support during the process. The present study aimed to investigate the chemical and physical properties of the Alg-Gel-PD bioink, and its effect on embedded mouse mesenchymal stem cells (MSCs). MSCs showed increased proliferation and migration in 2D culture with an Alg-Gel-based bioink extract. Gene expression analysis confirmed MSC differentiation towards sweat gland cells. The extract had no effect on protein expression in differentiated cells. Mixing MSCs with the Alg-Gel-based bioink for 3D bioprinting resulted in gene and protein expression characteristic of differentiation, including YAP1 activation. The mechanical strength of the bioink was similar to that of mouse dermal tissue and scanning electron microscopy showed that PD induced a more regular pore structure, suggesting advantages for the physical properties of the embedded cells. This study determined the influence of bioink on cellular behavior, thereby promoting therapeutic stem cell function via 3D cell printing processes.

Abstract
DNA methylation is essential for spatiotemporally-regulated gene expression in embryonic development. TBX22 (Chr X: 107667964-107688978) functioning as a transcriptional repressor affects DNA binding, sumoylation, and transcriptional repression associated with X-linked cleft palate. This study aimed to explore the relationship and potential mechanism between TBX22 exon 5 methylation and palatal shelf fusion induced by all-trans retinoic acid (ATRA). We performed DNA methylation profiling, using MethylRAD-seq, after high throughput sequencing of mouse embryos from control (n=9) and ATRA-treated (to induce cleft palate, n=9) C57BL/6J mice at embryonic gestation days(E) 13.5, 14.5 and 16.5. TBX22 exon 5 was hyper-methylated at the CpG site at E13.5 (P=0.025, log2FC=1.5) and E14.5 (P=0.011, log2FC:1.5) in ATRA-treated, whereas methylation TBX22 exon 5 at the CpG site was not significantly different at E16.5 (P=0.808, log2FC=-0.2) between control and ATRA-treated. MSP results showed a similar trend consistent with the MethylRAD-seq results. qPCR showed the change in TBX22 exon 5 expression level negatively correlated with its TBX22 exon 5 methylation level. These results indicate that changes in TBX22 exon 5 methylation might play an important regulatory role during palatal shelf fusion, and may enlighten the development of novel epigenetic biomarkers in the treatment of CP in the future.

Abstract
Circular RNAs (circRNAs) serve as competing endogenous RNAs (ceRNAs) and indirectly regulate gene expression through shared microRNAs (miRNAs). However, the regulatory mechanisms of circRNA as ceRNA associated with the fusion of palatal shelves in palatogenesis are yet unclear. This study aimed to explore the potential mechanism underlying the role of circRNA as ceRNA in cleft palate (CP). First, we systematically analyzed RNA-seq and miRNA-seq data after high-throughput sequencing for embryonic palatal shelf tissues from a mouse CP model induced by maternal exposure to all-trans retinoic acid on embryonic gestation day 14.5 (E14.5). Thirty-nine circRNAs, 18 miRNAs, and 936 messenger RNAs (mRNAs) were significantly dysregulated (log2 [fold change {FC}] > 1; P < 0.05). Thereafter, we constructed a circRNA-associated ceRNA network. Finally, we determined the circRNA_0954-miRNA-881-3p-PRKAR1α ceRNA network as a hub involved in palatogenesis. Gene Ontology analysis revealed that ceRNA-related genes were associated with facial morphogenesis and developmental gene silencing. Kyoto Encyclopedia of Genes and Genomes pathway analysis indicated that ceRNA-related genes are involved in apoptosis (P < 0.05, fold enrichment >1). Quantitative reverse transcription polymerase chain reaction was performed to verify the results of ceRNA analysis. We found that the circRNA-miRNA-mRNA ceRNA network is involved in palatogenesis. The present results imply that circRNA_0954-miRNA-881-3p-PRKAR1α ceRNA network may cause dysfunctional palatal fusion and might facilitate the development of novel epigenetic biomarkers to treat CP in the future.

Abstract
BACKGROUND Autophagy and apoptosis are involved in embryogenesis. However, little is known about the regulatory mechanism of AMBRA1-mediated autophagy and apoptosis associated with epithelial-mesenchymal transition (EMT) in the development of cleft palate (CP). This study is aimed to elucidate a novel regulatory mechanism by which AMBRA1 regulates autophagy and apoptosis associated with EMT during palatal fusion. METHODS We performed lncRNA and mRNA co-expression profile analysis on embryonic gestation day 14.5 (E14.5) mouse embryos from control (n=3) and all-trans retinoic acid-treated (to induce cleft palate, n=3) C57BL/6J mice. Functional prediction for transcription factor (TF)-target gene relationship, which was obtained using Gene Ontology/Kyoto Encyclopedia of Genes and Genomes analyses (GO/KEGG) pathway analysis, identified the regulatory "lncRNA-TF-target gene" using the trans model. RESULTS The trans analysis revealed that some TFs (e.g., LEF1, SMAD4, and FOXD3) regulate lncRNA and gene expression. Finally, we identified a NONMMUT034790.2-LEF1-AMBRA1 trans-regulatory network associated with CP. Our results indicate that AMBRA1 might be a novel epigenetic biomarker in palatogenesis. CONCLUSIONS AMBRA1-mediated autophagy and apoptosis associated with EMT by a NONMMUT034790.2-LEF1-AMBRA1 trans-regulatory network might be an important mechanism underlying dysfunctional palatal fusion.

Abstract
BACKGROUND Epithelial-mesenchymal transition (EMT) of the medial edge epithelium (MEE) occurs through fusion of the palatal shelves and is a crucial step in palatogenesis. The key genes, however, and the related signaling pathway of EMT are not yet fully understood. Therefore, the aim of this study was to reveal the key genes and the related signaling pathway of EMT during palatal fusion. MATERIALS AND METHODS C57BL/6J mice at embryonic gestation day 14.5 (E14.5; n = 6) were used to establish the cleft palate model for mRNA-Seq (HiSeq X Ten). The Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed for functional annotations of the differentially expressed genes. Quantitative polymerase chain reaction (qPCR) assays were used to validate the RNAseq data. RESULTS A total of 936 differentially expressed genes, including 558 upregulated and 378 downregulated genes were identified in cases versus controls, respectively. Among these genes, the GO analysis showed that Lymphoid Enhancer-Binding Factor 1 (LEF1) and SMAD Family Member 3 (SMAD3) significantly enriched biological processes, which were EMT related. The KEGG analysis showed that these genes regulated EMT through the Hippo signaling pathway. LEF1 and SMAD3 were downregulated, and the qPCR results corroborated the RNA-seq data. CONCLUSIONS These results demonstrate that LEF1 and SMAD3 inhibits EMT at the MEE through the Hippo signaling pathway; and that this could contribute to cleft palate formation in embryonic palatal fusion at E 14.5.

Abstract
BACKGROUND Increased vitamin B6 catabolism related to inflammation, as measured by the PAr index (the ratio of 4-pyridoxic acid over the sum of pyridoxal and pyridoxal-5'-phosphate), has been positively associated with lung cancer risk in two prospective European studies. However, the extent to which this association translates to more diverse populations is not known. MATERIALS AND METHODS For this study, we included 5323 incident lung cancer cases and 5323 controls individually matched by age, sex, and smoking status within each of 20 prospective cohorts from the Lung Cancer Cohort Consortium. Cohort-specific odds ratios (ORs) and 95% confidence intervals (CIs) for the association between PAr and lung cancer risk were calculated using conditional logistic regression and pooled using random-effects models. RESULTS PAr was positively associated with lung cancer risk in a dose-response fashion. Comparing the fourth versus first quartiles of PAr resulted in an OR of 1.38 (95% CI: 1.19-1.59) for overall lung cancer risk. The association between PAr and lung cancer risk was most prominent in former smokers (OR: 1.69, 95% CI: 1.36-2.10), men (OR: 1.60, 95% CI: 1.28-2.00), and for cancers diagnosed within 3 years of blood draw (OR: 1.73, 95% CI: 1.34-2.23). CONCLUSION Based on pre-diagnostic data from 20 cohorts across 4 continents, this study confirms that increased vitamin B6 catabolism related to inflammation and immune activation is associated with a higher risk of developing lung cancer. Moreover, PAr may be a pre-diagnostic marker of lung cancer rather than a causal factor.

Abstract
BACKGROUND Increasing evidence indicates that long non-coding RNAs (lncRNAs) play crucial regulatory roles in epithelial-mesenchymal transition (EMT). However, the regulatory mechanisms during EMT of the medial edge epithelium (MEE) remain elusive. The aim of this work is to reveal a novel lncRNA-regulated dysfunction of EMT involved in the development of cleft palate (CP). METHODS C57BL/6 J mice at embryonic gestation day 14.5 (n = 6, 3 case samples vs. 3 control samples) were used to establish the CP model for lncRNA-mRNA co-expression profile analysis after high-throughput sequencing. Functional predictions for the differentially expressed lncRNA-mRNA co-expression with transcription factor (TF)-target gene relationship Gene Ontology/Kyoto Encyclopedia of Genes and Genomes pathway (GO/KEGG) analyses identified the regulatory "lncRNA-TF-target gene" trans model. RESULTS A total of 583 differentially expressed lncRNAs and 703 differentially expressed mRNAs were identified. The results of trans analysis revealed that some TFs (LEF1, SMAD4, and FOXD3) regulate lncRNAs and gene expression. Finally, we identified the NONMMUT034790.2-LEF1-SMAD7 co-expression trans-regulatory network that might be associated with CP. CONCLUSIONS Our results revealed that NONMMUT034790.2 might be a novel epigenetic biomarker in CP. The integration of lncRNA modulators into trans-regulatory networks will further enhance our understanding of lncRNA functions and regulatory mechanisms during palatal fusion in ATRA-induced mouse CP.

Abstract
OBJECTIVE Cleft palate (CP) is a congenital birth defect caused by the failure of palatal fusion. Little is known about the potential role of DNA methylation in the pathogenesis of CP. This study aimed to explore the potential role of DNA methylation in the mechanism of CP. METHODOLOGY We established an all-trans retinoic acid (ATRA)-induced CP model in C57BL/6J mice and used methylation-dependent restriction enzymes (MethylRAD, FspEI) combined with high-throughput sequencing (HiSeq X Ten) to compare genome-wide DNA methylation profiles of embryonic mouse palatal tissues, between embryos from ATRA-treated vs. untreated mice, at embryonic gestation day 14.5 (E14.5) (n=3 per group). To confirm differentially methylated levels of susceptible genes, real-time quantitative PCR (qPCR) was used to correlate expression of differentially methylated genes related to CP. RESULTS We identified 196 differentially methylated genes, including 17,298 differentially methylated CCGG sites between ATRA-treated vs. untreated embryonic mouse palatal tissues (P<0.05, log2FC>1). The CP-related genes Fgf16 (P=0.008, log2FC=1.13) and Tbx22 (P=0.011, log2FC=1.64,) were hypermethylated. Analysis of Fgf16 and Tbx22, using Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG), identified 3 GO terms and 1 KEGG pathway functionally related to palatal fusion. The qPCR showed that changes in expression level negatively correlated with methylation levels. CONCLUSIONS Taken together, these results suggest that hypermethylation of Fgf16 and Tbx22 is associated with decreased gene expression, which might be responsible for developmental failure of palatal fusion, eventually resulting in the formation of CP.

Abstract
Epithelial-mesenchymal transformation of the medial edge epithelium is the most crucial process in embryonic palatal fusion. This study aimed to explore the relationship and potential mechanism between enhancer DNA methylation and mRNA expression of histone deacetylase 4 (HDAC4) during palatal fusion induced by maternal exposure to all-trans retinoic acid (ATRA). Pregnant mice were administered ATRA (70 mg/kg) by gavage at embryonic gestation day 10.5 (E10.5) to establish a cleft palate (CP) model in C57BL/6J mice. Control groups were given an equivalent volume of corn oil. Pregnant mice were dissected at E14.5 (n = 6) to obtain embryonic palates. HDAC4 enhancer DNA methylation data were obtained from a previous MethylRAD-seq. Methylation-specific polymerase chain reaction (MSP) and real-time quantitative PCR were used to quantify enhancer methylation and the mRNA expression level of HDAC4. Enhancer DNA methylation at a non-CpG site within the HDAC4 gene was hyper-methylated at E14.5 (P: 0.011, log2 FC:1.67). The MSP results indicated a similar trend, in agreement with the MethylRAD-seq results. The change in the HDAC4 expression level was negatively correlated with its enhancer DNA methylation level, at the non-CpG site, during palatal fusion induced by ATRA. Enhancer DNA methylation of HDAC4 might play an important regulatory role during palatogenesis, especially in embryonic palatal fusion at E 14.5, and may facilitate the development of novel epigenetic biomarkers in the treatment of CP.

Abstract
DNA methylation epigenetically regulates gene expression. This study is aimed to investigate genome-wide DNA methylations involved in the regulation of palatal fusion in the all-trans retinoic acid-induced mouse cleft palate model. There were 4,718,556 differentially CCGG methylated sites and 367,504 CCWGG methylated sites for 1497 genes between case and control embryonic mouse palatal tissues. The enhancers (HDAC4 and SMAD3) and promoter (MID1) of these three genes had cis-acting element methylation. HDAC4 is localized within the CCWGG, while MID1 and SMAD3 are localized within the CCGG of the gene intron. The methylation-specific polymerase chain reaction data confirmed the MethylRAD-seq results, while the quantitative reverse transcriptase-polymerase chain reaction result showed that changes in gene expression inversely were associated with the cis-acting element methylation of the gene during retinoic acid-induced palatal fusion. The GO and KEGG data showed that these three genes could regulate cell proliferation, skeletal muscle fiber development, and development-related gene signaling or activity. The cis-acting element methylation of HDAC4, SMAD3, and MID1 may play a regulatory role during palatal fusion. Further research is needed to verify these novel epigenetic biomarkers for cleft palate.

Abstract
Epithelial mesenchyme transformation (EMT) of the medial edge epithelium (MEE) is the crucial process during palatal fusion. This work is aimed to elucidate the enhancer regulatory mechanism by genome-wide DNA methylation analysis of EMT during palatal fusion. Over 800 million clean reads, 325 million enzyme reads, and 234 million mapping reads were generated. The mapping rate was 68.85-74.32%, which included differentially methylated 17299 CCGG sites and 2363 CCWGG sites (p < 0.05, log2FC >1). Methylated sites in intron and intergenic regions were more compared to other regions of all DNA elements. GO and KEGG analysis indicated that differential methylation sites related to embryonic palatal fusion genes (HDAC4, TCF7L2, and PDGFRB) at the enhancer were located on CCWGG region of non-CpG islands. In addition, the results showed that the enhancer for HDAC4 was hypermethylated, whereas the enhancers for TCF7L2 and PDGFRB were hypomethylated. The methylation status of enhancer regions of HDAC4, PDGFRB, and TCF7L2, involved in the regulation of the EMT during palatal fusion, may enlighten the development of novel epigenetic biomarkers in the treatment of cleft palate.

Abstract
Diabetic foot ulcer is a chronic, refractory, frequent complication in diabetic patient. Its treatment often requires multidisciplinary joint efforts, diverse strategies have been adopted to address this annoying issue, including stem cell-based therapy/acellular dermal matrix/negative pressure wound therapy etc. However, consensus has not been reached. To assess the current evidence regarding the efficiency and potential advantages of stem cell-based therapy compared with conventional standard treatment and/or placebo in the treatment of diabetic foot ulcer. A comprehensive search in PubMed, EmBase, Cochrane Central and Web of Science databases was conducted during December 2016 and a systematic review and meta-analysis of all relevant studies were performed. A total of 7 studies that involved 224 diabetic foot patients, classified as Wagner grades 1-5, were analyzed. The pooled results confirmed the benefits of using the stem cell treatment. Partial and/or complete healing were significantly higher in the stem cell group compared with the control group (77.4% vs. 31.9%; RR: 2.22; 95% CI, 1.65-2.98). Subgroup analysis on ABI and TCP02 also confirmed the results. The present meta-analysis indicates that stem cell-based therapy can enhance the healing of diabetic foot ulcers and is associated with lesser pain, lower amputation rate and improved prognosis compared with normal treatment. Well-designed randomized controlled trials are required in the future in order to confirm and update these findings.

Abstract
BACKGROUND Skin imaging analysis, acting as a supplement to noninvasive bioengineering devices, has been widely used in medical cosmetology and cosmetic product evaluation. The main aim of this study is to assess the differences and correlations in measuring skin spots, wrinkles, vascular features, porphyrin, and pore between two commercially available image analysis software. MATERIALS AND METHODS Seventy healthy women were included in the study. Before taking pictures, the dermatologist evaluated subjects' skin conditions. Test sites included the forehead, cheek, and periorbital skin. A 2 × 2 cm cardboard was used to make a mark on the skin surface. Pictures were taken using VISIA® under three kinds light conditions and analyzed using VISIA® and IPP® respectively. RESULTS (1) Skin pore, red area, ultraviolet spot, brown spot, porphyrin, and wrinkle measured with VISIA® were correlated with those measured with IPP® (P < .01). (2) Spot, wrinkle, fine line, brown spot, and red area analyzed with VISIA® were correlated with age on the forehead and periorbital skin (P < .05). L-value, Crow's feet, ultraviolet spot, brown spot, and red area analyzed with IPP® were correlated with age on the periorbital skin (P < .05). (3) L-value, spot, wrinkle, fine line, porphyrin, red area, and pore analyzed with VISIA® and IPP® showed correlations with the subjective evaluation scores (P < .05). CONCLUSIONS VISIA® and IPP® showed acceptable correlation in measuring various skin conditions. VISIA® showed a high sensibility when measured on the forehead skin. IPP® is available as an alternative software program to evaluate skin features.

Abstract
OBJECTIVES To explore the characteristics of Helicobacter pylori resistance in China and the association between antibiotic resistance and several clinical factors. METHODS H. pylori strains were collected from patients in 13 provinces or cities in China between 2010 and 2016. Demographic data including type of disease, geographic area, age, gender and isolation year were collected to analyse their association with antibiotic resistance. Antibiotic resistance was detected using the Etest test and the Kirby-Bauer disc diffusion method. RESULTS H. pylori were successfully cultured from 1117 patients. The prevalence of metronidazole, clarithromycin (CLA), azithromycin, levofloxacin (LEV), moxifloxacin, amoxicillin (AMO), tetracycline and rifampicin resistance was 78.2, 22.1, 23.3, 19.2, 17.2, 3.4, 1.9 and 1.5%, respectively. No resistance to furazolidone was observed. The resistance rates to LEV and moxifloxacin were higher in strains isolated from patients with gastritis compared to those with duodenal ulcer and among women. Compared to patients ≥40 years old, younger patients exhibited lower resistance rates to CLA, azithromycin, LEV and moxifloxacin. The resistance rates to CLA and AMO were higher in strains isolated more recently, and we also found that the prevalence of resistance to metronidazole, CLA, azithromycin and AMO were significantly different among different regions of China. CONCLUSIONS The resistance rates to metronidazole, CLA and LEV were high in China. Patient age, gender, disease and location were associated with the resistance of H. pylori to some antibiotics. Furazolidone, AMO and tetracycline are better choices for H. pylori treatment in China.

Abstract
Background: In contrast to the consistent evidence for obesity and colorectal cancer (CRC) risk, the impact of obesity in CRC patients is less clear. In a well-characterised cohort of CRC patients, we prospectively evaluated class I and class II obesity with survival outcomes. Methods: The CRC patients (N=634) were followed from the date of diagnosis until disease progression/first recurrence (progression-free survival (PFS)) or death (overall survival (OS)). Body mass index (BMI) was calculated from reported usual weight prior to diagnosis. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated in models adjusted for clinicopathologic, treatment, and lifestyle factors. Results: Over a median follow-up of 4 years, 208 (33%) patients died and 235 (37%) recurred or progressed. Class II obesity, as compared with either overweight or normal weight, was associated with an increased risk of death (HR and 95% CI: 1.55 (0.97–2.48) and 1.65 (1.02–2.68), respectively), but no clear association was observed with PFS. In analyses restricted to patients who presented as stages I–III, who reported stable weight, or who were aged <50 years, obesity was associated with a significant two- to five-fold increased risk of death. Conclusions: In CRC patients evaluated at a large cancer centre, severely obese patients experienced worse survival outcomes independent of many other factors.

Abstract
BACKGROUND Respiratory syncytial virus (RSV) is a common community-acquired pathogen responsible for a substantial disease burden in adults. We investigated the outcomes after RSV infection in hospitalized adults over a 3-year period. METHODS This single-center, retrospective study identified 174 patients hospitalized with RSV upper or lower respiratory tract infection (LRTI) between January 1, 2009 and June 30, 2012. Clinical data were extracted from medical records. The primary outcome analyzed was all-cause mortality, defined as death during the index hospital admission. Subjects were divided into 3 groups for comparison: hematopoietic stem cell transplant (HSCT) patients, solid organ transplant (SOT) patients, and non-transplant patients. RESULTS In our study, 41/174 (23.6%) were HSCT recipients and 28/174 (16.1%) were SOT recipients. Twelve of 174 (6.9%) died. Death occurred in 2/41 (4.9%) HSCT and 3/28 (10.7%) SOT recipients, compared to 7/106 (6.6%) non-transplant patients. When compared to the non-transplant cohort, HSCT and SOT were not found to be significant risk factors for mortality (P = 0.685 and 0.645, respectively). In multivariate logistic regression, age >60 was associated with mortality (P = 0.019), while lymphopenia on admission trended toward an association with death (P = 0.054). HSCT patients were less likely to be admitted to an intensive care unit (odds ratio [OR] 0.26, P = 0.04), but were significantly more likely to receive ribavirin therapy (OR 11.62, P < 0.0001). CONCLUSION Adults hospitalized with RSV LRTI are at significant risk of mortality, and this risk may be increased in patients age >60 or with lymphopenia on admission. This study did not identify any significant increased mortality or morbidity associated with RSV infection in immune suppressed transplant recipients vs. patients who had not received a transplant.
