Abstract
BACKGROUND Previous models for predicting delirium after cardiac surgery remained inadequate. This study aimed to develop and validate a machine learning-based prediction model for postoperative delirium (POD) in cardiac valve surgery patients. METHODS The electronic medical information of the cardiac surgical intensive care unit (CSICU) was extracted from a tertiary and major referral hospital in southern China over 1 year, from June 2019 to June 2020. A total of 507 patients admitted to the CSICU after cardiac valve surgery were included in this study. Seven classical machine learning algorithms (Random Forest Classifier, Logistic Regression, Support Vector Machine Classifier, K-nearest Neighbors Classifier, Gaussian Naive Bayes, Gradient Boosting Decision Tree, and Perceptron.) were used to develop delirium prediction models under full (q = 31) and selected (q = 19) feature sets, respectively. RESULT The Random Forest classifier performs exceptionally well in both feature datasets, with an Area Under the Curve (AUC) of 0.92 for the full feature dataset and an AUC of 0.86 for the selected feature dataset. Additionally, it achieves a relatively lower Expected Calibration Error (ECE) and the highest Average Precision (AP), with an AP of 0.80 for the full feature dataset and an AP of 0.73 for the selected feature dataset. To further evaluate the best-performing Random Forest classifier, SHAP (Shapley Additive Explanations) was used, and the importance matrix plot, scatter plots, and summary plots were generated. CONCLUSIONS We established machine learning-based prediction models to predict POD in patients undergoing cardiac valve surgery. The random forest model has the best predictive performance in prediction and can help improve the prognosis of patients with POD.

Abstract
BACKGROUND Infective endocarditis is a life-threatening uncommon infectious disease, and we aimed to explore the clinical utility of venous or arterial blood-based metagenomic next-generation sequencing (mNGS) approaches to diagnose left-sided infective endocarditis (LSIE). METHODS We prospectively studied 79 LSIE patients who received valvular surgery in our hospital. Results of blood culture, valve culture, venous blood-based mNGS, arterial blood-based mNGS, venous blood-based mNGS plus blood culture, and arterial blood-based mNGS plus blood culture were evaluated and compared. RESULTS Both venous blood- and arterial blood-based mNGS methods displayed significantly higher positive detection rates than blood culture and valve culture (43.0 %, 49.4 % vs. 32.9 %, 19.0 %; P < 0.001). Strikingly, when combining blood-based mNGS and blood culture, the positive rate could be further improved to more than 60 %. Moreover, we found mNGS LSIE detection was closely associated with preoperative leukocyte (P = 0.027), neutrophil value (P = 0.018), vegetation ≥ 14 mm (P = 0.043), and vegetations in aortic valve (P = 0.048). In addition, we discovered that blood-based mNGS had a superir capacity over blood culture to detect gram-negative bacteria, fungi, Bartonella Quintana, and mixed infections than blood culture. CONCLUSION This study indicates that venous blood- and arterial blood-based mNGS displayed high positive rate in the rapid detection of pathogens in high-risk LSIE patients.

Abstract
Heart failure (HF) is a major health burden worldwide, with approximately half of HF patients having a comorbid cognitive impairment (CI). However, it is still unclear how CI develops in patients with HF. In the present study, a mice model of heart failure was established by ligating the left anterior descending coronary artery. Echocardiography 1 month later confirmed the decline in ejection fraction and ventricular remodeling. Cognitive function was examined by the Pavlovian fear conditioning and the Morris water maze. HF group cued fear memory, spatial memory, and learning impairment, accompanied by activation of glial cells (astrocytes, microglia, and oligodendrocytes) in the hippocampus. In addition, the mitochondrial biogenesis genes TFAM and SIRT1 decreased, and the fission gene DRP1 increased in the hippocampus. Damaged mitochondria release excessive ROS, and the ability to produce ATP decreases. Damaged swollen mitochondria with altered morphology and aberrant inner-membrane crista were observed under a transmission electron microscope. Finally, Akt/mTOR signaling was upregulated in the hippocampus of heart failure mice. These findings suggest that activation of Akt/mTOR signaling, glial activation, and mitochondrial dynamics imbalance could trigger cognitive impairment in the pathological process of heart failure mice.

Abstract
PURPOSE/OBJECTIVE(S) Despite the long-term survival rate for children with head and neck rhabdomyosarcoma (HNRMS) has improved to over 70-80% due to advancements in therapeutic approaches, the survival outcomes for adult HNRMS have not been thoroughly investigated. Our study aims to compare and analyze the survival outcomes of adult and pediatric patients with non-metastatic HNRMS, with a focus on the effect of different local treatment methods on disease outcomes. MATERIALS/METHODS We conducted a retrospective analysis of data from the Surveillance, Epidemiology, and End Results (SEER) database covering the period from 2004 to 2018. Our study population consisted of patients with Head and Neck Rhabdomyosarcoma (HNRMS) who had not developed distant metastases and received at least one local treatment, either radiotherapy or surgery. The comparison of overall survival (OS) and cancer-specific survival (CSS) was performed between the adult and pediatric patient groups, and between patients who received surgery (with or without radiotherapy) and those who received radiotherapy only (non-surgery). RESULTS In the study of 550 patients diagnosed with Head and Neck Rhabdomyosarcoma (HNRMS), data was collected from 181 (32.9%) adult and 369 (67.1%) pediatric patients. The results showed that the adult patient group had a significantly worse outcome compared to the pediatric group in terms of 5-year overall survival (OS) rate (34.9% vs 81.6%, P<0.001) and 5-year cancer specific survival (CSS) rate (59.96% vs 87.48%, P<0.001). Of these patients, 308(56%) underwent radical surgery, with 228 (41.5%) receiving a combination of radiation and surgery and the remaining 242 (44%) receiving radiation therapy alone. No significant differences were found in 5-year OS and CSS rates between the surgery and non-surgery (radiation only) groups in adult patients (34.9% vs 35.0%, P = 0.900; 60.2% vs 59.6%, P = 0.988). However, there were slight differences observed in the pediatric patient group, with the 5-year OS and CSS rates being higher for the surgery group compared to the non-surgery group (86.9% vs 75.9%, P = 0.001 and 90.6% vs 84.2%, P = 0.054, respectively). CONCLUSION The results of this cohort study indicate that age plays a crucial role in predicting survival outcomes in patients diagnosed with Head and Neck Rhabdomyosarcoma (HNRMS). The findings highlight the need for age-specific treatment strategies for HNRMS patients. While the data suggests that radiotherapy may be a viable first-line option for non-metastatic adult HNRMS patients, additional research is required to validate these trends.

Abstract
PURPOSE/OBJECTIVE(S) Gemcitabine-cisplatin (GP) as the most commonly used induction chemotherapy is the standard first-line systemic treatment for advanced nasopharyngeal carcinoma. However, the toxicity of three cycles induction chemotherapy following on chemoradiotherapy remains a pertinent issue. Additional monoclonal antibody against human programmed death-1 (PD-1) has shown promising efficacy in recurrent or metastatic nasopharyngeal carcinoma. MATERIALS/METHODS In this study, we compared three cycles of gemcitabine and cisplatin as classical induction chemotherapy with two cycles of induction chemotherapy plus toripalimab, and then both groups treated with the similar concurrent chemoradiotherapy. Patients with locoregionally advanced nasopharyngeal carcinoma staging T4 or N3 were randomly assigned in a 1:1 ratio to receive gemcitabine (at a dose of 1 g per square meter of body-surface area on days 1 and 8) plus cisplatin (80 mg per square meter on day 1-3), administered every 3 weeks for three cycles, or GP combined with toripalimab (at a dose of 240mg) for two cycles. The primary end point was recurrence-free survival (i.e., freedom from disease recurrence [distant metastasis or locoregional recurrence] or death from any cause) in the intention-to-treat population. Secondary end points included overall survival, treatment adherence, and safety. RESULTS A total of 60 patients were included in the trial (30 patients in the toripalimab combined induction chemotherapy group and another 30 in the standard-therapy group). Among 60 patients evaluable for response assessment after induction therapy, all patients had overall response in combined group, including 10 patients (30%) with complete response (CR) in the primary tumor site. 21 patients (70%) were evaluated as partial response (PR) in the standard induction chemotherapy, and another 9 patients were assessed as SDa. At a median follow-up of 27.6 months, the 6-months, 1-, 2-year recurrence-free survival was 100% vs 86.7%, 100% vs 80%, 93% vs 70% in the toripalimab combined induction chemotherapy group and standard-therapy group (stratified hazard ratio for recurrence or death, 0.62; 95% confidence interval [CI], 0.38 to 0.87; P = 0.001). Overall survival at 2 years was 93.3% and 100%, respectively (stratified hazard ratio for death, 0.53; 95% CI, 0.29 to 0.79). The incidence of acute adverse events of grade 3 or 4 was 76.8% in the standard-induction chemotherapy group and 56% in the standard-therapy group, with a higher incidence of neutropenia, thrombocytopenia, anemia, nausea, and vomiting in the induction chemotherapy group. The incidence of grade 3 or 4 late toxic effects was 10.2% in the induction chemotherapy group and 10.4% in the combined-therapy group. CONCLUSION Two cycles of toripalimab combined with induction chemotherapy of and CCRT shows excellent distant metastatic control with acceptable safety, which is a new promising and effective systemic therapy regimen for high-risk of metastatic NPC patients.

Abstract
PURPOSE/OBJECTIVE(S) Local regional radiotherapy combined with systemic chemotherapy significantly improves the prognosis of patients with metastatic nasopharyngeal carcinoma (NPC). Immunochemotherapy has become the first-line treatment for initial metastatic NPC. This study evaluated the safety and efficacy of local regional radiotherapy combined with immunochemotherapy as the first-line treatment of metastatic NPC. MATERIALS/METHODS Patients with histologically proven de novo metastatic NPC who received immunotherapy and chemotherapy followed by local-regional radiotherapy were included from 2 cancer centers. Toxicity and treatment response were assessed using CTCAE 5.0 and RECIST 1.1, respectively. Overall survival (OS) and progression free survival (PFS) were analyzed using the Kaplan-Meier method. RESULTS From 2019 to 2021, a total of 16 patients were retrospectively analyzed. The median age was 44.5-year-old (range 16-76). Patients with ≥3 metastatic lesions accounts for 58.8%. Bone metastasis was the most common metastatic site. The chemotherapy regimens were paclitaxel/gemcitabine and cisplatin. Toripalimab, camrelizumab and sintilimab were used for immunotherapy. All patients completed the local regional radiotherapy with 69.96Gy for primary nasopharyngeal tumor and positive lymph nodes, 60.06Gy for high-risk region and 50ཞ54.45Gy for low-risk region. Seven patients underwent radiotherapy for metastatic lesions. The median follow-up was 20.5 months (range 6-38 months). Two-year OS was 100%. Three patients experienced distant progression. One-year and 2-year PFS rate was 93.8% and 76.7%, respectively. After combination of chemotherapy and immunotherapy, the overall response rate (ORR) was 93.7% with a complete response (CR) of 6.3%. At the end of radiotherapy, the ORR was 100%. Nine patients (56.3%) achieved CR. Radiotherapy related acute severe (grade 3 or higher) toxicity was dermatitis (1/16, 6.3%) and mucositis (2/16, 12.5%). Immunotherapy related hypophysitis and capillary hyperplasia was 6.3% and 6.3%, respectively. No long-term toxicity was observed. CONCLUSION Loco-regional radiotherapy provided a promising efficacy with modest toxicity for patients with metastatic nasopharyngeal carcinoma who received immunochemotherapy.

Abstract
Objective: To systematically integrate and analyze the breast cancer screening rates among females in China and to estimate the composition of different screening service types. Methods: Based on core literature, relevant official websites, projects/survey reports, and information on breast cancer screening rates of Chinese females were extracted and analyzed, and the screening rates for 40-69 years old and 35-64 years old were standardized and compared using 2010 China's population structure. The literature review method was used to retrieve the journal literature related to the composition of breast cancer screening services types (organized screening, physical examination and opportunistic screening). The number of detected literature and the median sample size of individual screening people of the three screening service types were analyzed, and used them as weights to estimate the composition of screening service types. Results: A total of 6 related national surveys on breast cancer screening rate were identified, including 2 from the National Health Service Surveys (broader definition of "breast screening" in 2013, 2018) and 4 from the chronic disease monitoring system of China CDC (the exact definition of "breast cancer screening" in 2010, 2013 and twice in 2015). The age-standardized analysis indicated that 1-year, 2-year and 3-year breast cancer screening rates in 2015 among females in China aged 40-69 years old were 16.9%, 20.2% and 21.4%, respectively. The ever-breast cancer-screened rates were 21.1% in 2013 and 23.5% in 2015 among females aged 40-69, and the corresponding rates were 23.3% and 25.7%, respectively, among females aged 35-64. When taking the literature published in 2015 for further literature review, 130 articles were included, in which the proportions of numbers of reports on organized screening, physical examination, and opportunistic screening were 71.0%, 23.7%, and 5.3%, respectively. Along with the extracted data on median sample sizes (shown in the main text) by breast cancer screening types, it was estimated that the individual service volume of corresponding screening types accounted for 88.0%, 11.2% and 0.8% among all the screened females in China in 2015. Conclusions: The breast cancer screening rates among females of appropriate age in China in 2015 are higher than those in 2013. The literature review analysis preliminarily suggested that the current breast cancer screening service type in China is mainly organized screening service.

Abstract
Increasing the copy number of peptides is an effective method to genetically engineer recombinant expression and obtain umami peptides in large quantities. However, the umami taste value of multicopy number umami peptides is lower than the single ones, thus limiting the industrial application of recombinantly expressed umami peptides. With aims to solve this problem, modification of an umami beefy meaty peptide (BMP) with trypsin hydrolysis sites was carried out via homology modeling and molecular docking in this study. A total of 1286 modified peptide sequences were created and molecularly simulated for docking with the homology modeling-constructed umami receptor (T1R1/T1R3), and 837 peptides were found to be better docked than the BMP. Afterward, the MLSEDEGK peptide with the highest docking score was synthesized. And umami taste evaluation results demonstrated that this modified peptide was close to that of monosodium glutamate (MSG) and BMP, as confirmed by electronic tongue and sensory evaluation (umami value: 8.1 ± 0.2 for BMP; 8.2 ± 0.3 for MLSEDEGK peptide). Meanwhile, mock trypsin digestion of eight copies of MLSEDEGK peptide results showed that the introduced digestion sites were effective. Therefore, the novel modified BMP in this study has the potential for large-scale production by genetic engineering.

Abstract
This retrospective study aimed to derive the clinical phenotypes of ventilated ICU patients to predict the outcomes on the first day of ventilation. Clinical phenotypes were derived from the eICU Collaborative Research Database (eICU) cohort via cluster analysis and were validated in the Medical Information Mart for Intensive Care (MIMIC-IV) cohort. Four clinical phenotypes were identified and compared in the eICU cohort (n = 15,256). Phenotype A (n = 3112) was associated with respiratory disease, had the lowest 28-day mortality (16%), and had a high extubation success rate (~80%). Phenotype B (n = 3335) was correlated with cardiovascular disease, had the second-highest 28-day mortality (28%), and had the lowest extubation success rate (69%). Phenotype C (n = 3868) was correlated with renal dysfunction, had the highest 28-day mortality (28%), and had the second-lowest extubation success rate (74%). Phenotype D (n = 4941) was associated with neurological and traumatic diseases, had the second-lowest 28-day mortality (22%), and had the highest extubation success rate (>80%). These findings were validated in the validation cohort (n = 10,813). Additionally, these phenotypes responded differently to ventilation strategies in terms of duration of treatment, but had no difference in mortality. The four clinical phenotypes unveiled the heterogeneity of ICU patients and helped to predict the 28-day mortality and the extubation success rate.

Abstract
Objective: To compare the differences to determine resting energy expenditure (REE) measured with indirect calorimetry and REE predicted by formula method and body composition analyzer in patients with decompensated hepatitis B cirrhosis, so as to provide theoretical guidance for the implementation of precision nutrition intervention. Methods: Patients with decompensated hepatitis B cirrhosis who were admitted to Henan Provincial People's Hospital from April 2020 to December 2020 were collected. REE was determined by the body composition analyzer and the H-B formula method. Results: were analyzed and compared to REE measured by the metabolic cart. Results A total of 57 cases with liver cirrhosis were included in this study. Among them, 42 were male, aged (47.93 ± 8.62) years, and 15 were female aged (57.20 ± 11.34) years. REE measured value in males was (1 808.14 ± 201.47) kcal/d, compared with the results calculated by the H-B formula method and the measured result of body composition, and the difference was statistically significant (P = 0.002 and 0.003, respectively). REE measured value in females was (1 496.60 ± 131.28) kcal/d, compared with the results calculated by the H-B formula method and the measured result of body composition, and the difference was statistically significant (P = 0.016 and 0.004, respectively). REE measured with the metabolic cart had correlation with age and area of visceral fat in men (P = 0.021) and women (P = 0.037). Conclusion: Metabolic cart use will be more accurate to obtain resting energy expenditure in patients with decompensated hepatitis B cirrhosis. Body composition analyzer and formula method may underestimate REE predictions. Simultaneously, it is suggested that the effect of age on REE in H-B formula should be fully considered for male patients, while the area of visceral fat may have a certain impact on the interpretation of REE in female patients.

Abstract
Objective: From a screening-focused perspective, to analyze the 30-year changes in disability adjusted life years (DALYs) caused by colorectal cancer (CRC) in China and in some other selected populations, to inform extent of burden of CRC and future related prevention and control in populations in China. Methods: Based on the data of Global Burden of Disease 2019 (GBD 2019), the DALYs, world standardized DALY rate, and the composition of different subgroups in China were collected. Joinpoint regression model was used to analyze the trend during 1990-2019, and comparison was made with the international data and population screening situation. The trend of DALY burden caused by CRC in China was predicted. Results: In 2019, the DALYs due to CRC in China was 6.395 million person-years, accounting for 26.3% of the global burden and 9.5% of all cancers burden in China; the DALYs in men accounted for 65.2%, in those aged ≥65 years old accounted for 44.8%, in the age group recommended by local screening guidelines (40-75 years) accounted for 73.7%. The years lived with disability accounted for 4.8%. Compared with 1990, the CRC-caused DALYs in China increased by 181.5% in 2019. Factors with the largest increase in the attributable percentage were high Body Mass Index (151.1%), diet high in red meat (86.4%) and diet high in processed meat (78.8%), etc. For DALY rate, it was 245.6/100 000 in 1990 and 320.6/100 000 in 2019, an increase of 30.5%. For reference, Australia (began in 2006), the UK (2006), and Japan (1992), where CRC population-wide screening has been conducted, had decreases in DALY rate of 36.0%, 28.6%, and 17.8%, respectively. The predication of DALYs suggested that without continued expansion of population-based screening, the DALYs in China would reach 7.7 million person-year-9.1 million person-year by 2030, an increase of 19.9%-41.8% compared with 2019. Conclusions: The burden of CRC-caused DALYs in China increased over the past 30 years, and would become more serious because of population aging and the concomitant disability problem. The age range recommended by the current local screening guideline could theoretically include 70% of the population from which the DALYs burden originates, however, the real-world population screening coverage is still limited. The observed decline in CRC-related DALY rate in selected countries was substantially due to the implementation of mass screening, indicating the importance of speedily expanding the population coverage of CRC screening in China.

Abstract
Background Low cardiac output syndrome (LCOS) is the most serious physiological abnormality with high mortality for patients after cardiac surgery. This study aimed to explore the multidimensional data of clinical features and outcomes to provide individualized care for patients with LCOS. Methods The electronic medical information of the intensive care units (ICUs) was extracted from a tertiary hospital in South China. We included patients who were diagnosed with LCOS in the ICU database. We used the consensus clustering approach based on patient characteristics, laboratory data, and vital signs to identify LCOS subgroups. The consensus clustering method involves subsampling from a set of items, such as microarrays, and determines to cluster of specified cluster counts (k). The primary clinical outcome was in-hospital mortality and was compared between the clusters. Results A total of 1,205 patients were included and divided into three clusters. Cluster 1 (n = 443) was defined as the low-risk group [in-hospital mortality =10.1%, odds ratio (OR) = 1]. Cluster 2 (n = 396) was defined as the medium-risk group [in-hospital mortality =25.0%, OR = 2.96 (95% CI = 1.97–4.46)]. Cluster 3 (n = 366) was defined as the high-risk group [in-hospital mortality =39.2%, OR = 5.75 (95% CI = 3.9–8.5)]. Conclusion Patients with LCOS after cardiac surgery could be divided into three clusters and had different outcomes.

Abstract
Background Emerging evidence has shown that exosome microRNAs (miRNAs) regulate the development of hepatocellular carcinoma (HCC). Here, the influences of miR-4800-3p on the progression of HCC were explored. Materials and Methods The expression of miR-4800-3p in the exosome derived by transforming growth factor beta 1 (TGF-β1)-treated HCC cells and the serum exosome isolated from HCC patients were identified by real-time PCR. The effects of TGF-β1 and the influences of Huh7-secreted exosomes and the effects of miR-4800-3p combined with/without STK25 on cell functions were explored using the EdU assay cloning experiments, wound healing assay, and Transwell assay. The corresponding molecular mechanisms were further detected using Western blot and real-time PCR assays. The combination of miR-4800-3p and STK25 was verified by the dual-luciferase and RNA pulldown assays. The influences of miR-4800-3p on the growth and epithelial–mesenchymal transformation (EMT) of implanted tumors were tested in vivo and further confirmed by Western blot. Results The miR-4800-3p expression was highly expressed in both exosomes derived by TGF-β1-treated HCC cells and the serum exosomes of HCC patients. In the cases of treatment with both Huh7-derived exosomes, the level of miR-4800-3p expression was highest, and the treatment of TGF-β1 could greatly promote the proliferation, stemness, migration, and invasion of HCC cells via upregulating the markers of stemness and EMT, including CD44, CD133, OCT4, N-cadherin, E-cadherin, and ZO-1. Similar results could be obtained when miR-4800-3p was overexpressed in HCC cells. Furthermore, downregulation of STK25 expression, a direct target gene of miR-4800-3p, could greatly rescue the malignant biological behaviors aggravated by overexpression of miR-4800-3p. This was achieved by suppressing the expression of CD44, CD133, OCT4, N-cadherin, and PCNA and activating the Hippo pathway while increasing E-cadherin and ZO-1. Similar results were also obtained in vivo that knockdown of miR-4800-3p expression suppressed tumor growth induced by Huh7-derived exosomes by mediating the EMT markers and the Hippo signaling pathway. Conclusion Exosomal miR-4800-3p could accelerate HCC development by regulating the Hippo signal by targeting STK25, which could be used as a new therapeutic target for HCC treatment.

Abstract
BACKGROUND Permanent epicardial pacing is the primary choice for neonates and infants with bradyarrhythmia. We reviewed mid-term outcomes after epicardial permanent pacemaker (EPPM) implantation in this age group. METHODS From Dec 1, 2008 to Dec 1, 2019, children who underwent EPPM implantation within the first year of life were included in our study. Patients were followed up for as long as 12 years, until Jun 11, 2021, for all-cause mortality and pacemaker reoperation. Kaplan-Meier and log-rank tests were used for analysis. RESULTS Of 31 consecutive patients [18 boys (58.1%) and 2 neonates (6.5%)] included in this study, 30 (96.8%) were discharged alive and assessed at a median follow-up of 3.9 years [interquartile range (IQR) 4.7]. The median age and weight of the patients were 156 days (IQR 217) and 5.3 kg (IQR 3.5), respectively, at the time of their operation. Twenty-five (80.6%) patients had congenital heart disease, and the main indication for pacing was postoperative atrioventricular block (AVB) in 21 (67.7%) patients. During follow-up, 3 (9.7%) patients died and there were a total of 9 pacing lead failures in 7 (22.6%) patients. The median longevity of leads (unipolar steroid-eluting) was 2.9 years (IQR 3.6). Freedom from lead reoperation was 90.3%, 72.0%, 65.5% and 49.1% at 1, 3, 5, and 8 years, respectively. The median longevity of the pacing generators was 3.3 years (IQR 2.8). Freedom from generator reoperation was 90.3%, 75.6%, 52.4% and 43.6% at 1, 3, 5 and 6 years, respectively. CONCLUSIONS The mid-term outcome of EPPM implantation in neonates and infants was acceptable. Neonates and infants with EPPM implants face the risk of repeated reoperations and all-cause death. A patient's prognosis can depend on regular follow-up, type of pacing lead and the presence of congenital heart malformations, especially complex congenital heart disease.

Abstract
We consider the problem of multiple hypothesis testing when there is a logical nested structure to the hypotheses. When one hypothesis is nested inside another, the outer hypothesis must be false if the inner hypothesis is false. We model the nested structure as a directed acyclic graph, including chain and tree graphs as special cases. Each node in the graph is a hypothesis and rejecting a node requires also rejecting all of its ancestors. We propose a general framework for adjusting node-level test statistics using the known logical constraints. Within this framework, we study a smoothing procedure that combines each node with all of its descendants to form a more powerful statistic. We prove a broad class of smoothing strategies can be used with existing selection procedures to control the familywise error rate, false discovery exceedance rate, or false discovery rate, so long as the original test statistics are independent under the null. When the null statistics are not independent but are derived from positively-correlated normal observations, we prove control for all three error rates when the smoothing method is arithmetic averaging of the observations. Simulations and an application to a real biology dataset demonstrate that smoothing leads to substantial power gains.

Abstract
Objective The present study aimed to prospectively evaluate the role of metagenomic next-generation sequencing (mNGS) in the etiological diagnosis of patients with perioperative infective endocarditis (IE). Methods From May 1st, 2019 to December 31st, 2020, a total of 99 patients with IE were enrolled in the present study according to the modified Duke criteria, etiological, and pathological results. 11 non-IE patients undergoing heart valve surgery in the same period were selected as the control group. A blood culture test was performed immediately after admission, and the valves harvested operatively were examined by blood culture and mNGS. Results In the IE group, there were 29 cases (29.3%) with positive blood culture, 16 cases (16.2%) with positive valve culture, and 85 cases (85.9%) with positive valve mNGS. Compared to culture-based detection, mNGS achieved better performance with a sensitivity, specificity, area under the curve (AUC) of 0.859, 0.727, and 0.793, respectively. The combined approach using culture and mNGS further improved the diagnostic accuracy (sensitivity 89.9%, specificity 72.7%, AUC 0.813). Preoperative white blood cell (P = 0.029) and neutrophils (P = 0.046) were identified as independent factors affecting the detection rate of mNGS. In the mNGS-positive group, 95 strains of pathogens were found and 10 cases were identified with mixed infection. There were 72 gram-positive bacteria and 14 gram-negative bacteria. mNGS positive group displayed higher species richness than mNGS negative group with enrichment of Streptococcus sanguis, Streptococcus buccalis, and Streptococcus griseus. Proteobacteria and Actinomycetes were enriched in mNGS negative group. Notably, six patients showed disconcordant results between culture and mNGS. Rothia aeria was identified in the blood culture, valve culture, and valve mNGS in one patient. Bartonella Quintana and Coxiella burnetii, which were fastidious intracellular bacteria, were found in two blood and valve culture-negative cases. Conclusions mNGS outperformed the conventional culture method and displayed high accuracy in detecting pathogens in IE patients. This study provided support for the use of mNGS in the etiological diagnosis of IE.

Abstract
Background The modification of N6-methyladenosine (m6A) is a dynamic and reversible course that might play a role in cardiovascular disease. However, the mechanisms of m6A modification in myocardial ischemia/reperfusion injury (MIRI) remain unclear. Methods A mouse model of MIRI and a cell model of oxygen-glucose deprivation/reperfusion (OGD/R) HL-1 cells were employed. In an in vivo study, the total RNA m6A modification levels were determined by dot blot, and the key genes related to m6A modification were screened by real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot. In an in vitro study, the effects of AlkB homolog 5 (ALKBH5), an RNA demethylase, on cell proliferation, cell injury, and apoptosis were detected by the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay, lactate dehydrogenase (LDH) and cardiac troponin-I (cTnI) levels, and flow cytometry. Besides, the m6A modification-changed and differentially expressed messenger RNA (mRNA) were determined by methylated RNA immunoprecipitation sequencing (MeRIP-seq) and RNA sequencing (RNA-seq) in ALKBH5-overexpressed HL-1 cells. Finally, the mRNA levels of the promising targeted gene were examined by RT-qPCR and its m6A modification levels were examined by MeRIP-qPCR. Results Our results showed that RNA m6A modification was involved in MIRI, in which ALKBH5 was downregulated. Functionally, by overexpressing or silencing ALKBH5 in experimental cells, we verified its protective properties on cell proliferation, cell injury, and apoptosis in the process of MIRI. Besides, we provided a mass of latent different mRNAs with m6A modification variation in ALKBH5-overexpressed HL-1 cells. Mechanistically, we further screened the most potential targeted mRNAs and suggested that triple functional domain (Trio) mRNA could be upregulated by ALKBH5 by reducing m6A level of Trio. Conclusions This study demonstrated that the downregulated ALKBH5 might contribute to MIRI process by increasing the m6A modification of Trio mRNA and downregulating Trio.

This study aims to investigate the effect of resveratrol on intrahepatic cholestasis of pregnancy (ICP) and its effect on the gut microbiome profiles, thus contributing to the potential therapeutic strategies for ICP. ICP rat models were established by injecting 17α-ethinylestradiol (EE) subcutaneously from the thirteenth day of gestation for four days and then treated with EE (D group, n=5), resveratrol (R group, n=5), or ursodeoxycholic acid (UDCA; U group, n=5) from the seventeenth to the twentieth day of gestation. Fecal samples were analyzed with 16S ribosomal RNA (rRNA) sequencing. In results: the gut microbiota of pregnant rats was characterized with reduced alpha diversity (Chao1 index), and significant variation in the microbiota structure (ANOSIM) was also observed after being treated with EE. The richness of four phyla and ten genera was upregulated, and five phyla and ten genera were downregulated by EE treatment. The dysbiosis of Bilophila, Ruminococcus, and Actinobacteria caused by EE treatment was reversed by resveratrol administration. There was a correlation between total bile acid and alanine aminotransferase in ICP rats. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis results suggested that the secondary bile acid biosynthesis was decreased, and the alanine, aspartate, and glutamate metabolism was increased after being treated with EE in pregnant rats. In conclusion, EE treatment could lead to gut microbiome dysbiosis and bile acid metabolism dysregulation in pregnant rats. Resveratrol could partially rescue gut microbiota dysbiosis and improve the biochemical characteristics caused by EE treatment.

Abstract
Root canal therapy is the common treatment for endodontic infections. Successful root canal therapy depends on favorable root canal preparation, root canal medication and three-dimensional obturation of the root canal system. The key to successful root canal therapy is to prevent re-infection of the highly complex root canal systems by removing infecious biofilms and bacterial toxins in the root canal system. The present paper reviews the pathogenic mechanism of the Enterococcus faecalis in the harsh environment of root canal system, the inflammation and immunity of refractory periapical periodontitis and the progress of infection control methods.

Abstract
BACKGROUND Mechanical ventilation (MV) is an important lifesaving method in intensive care unit (ICU). Prolonged MV is associated with ventilator associated pneumonia (VAP) and other complications. However, premature weaning from MV may lead to higher risk of reintubation or mortality. Therefore, timely and safe weaning from MV is important. In addition, identification of the right patient and performing a suitable weaning process is necessary. Although several guidelines about weaning have been reported, compliance with these guidelines is unknown. Therefore, the aim of this study is to explore the variation of weaning in China, associations between initial MV reason and clinical outcomes, and factors associated with weaning strategies using a multicenter cohort. METHODS This multicenter retrospective cohort study will be conducted at 17 adult ICUs in China, that included patients who were admitted in this 17 ICUs between October 2020 and February 2021. Patients under 18 years of age and patients without the possibility for weaning will be excluded. The questionnaire information will be registered by a specific clinician in each center who has been evaluated and qualified to carry out the study. DISCUSSION In a previous observational study of weaning in 17 ICUs in China, weaning practices varies nationally. Therefore, a multicenter retrospective cohort study is necessary to be conducted to explore the present weaning methods used in China. TRIAL REGISTRATION Chinese Clinical Trial Registry (ChiCTR) (No. ChiCTR2100044634).

Abstract
Objective: Based on the data of Global Burden of Disease 2019 data, to analyze the past, current, and future burden of disability-adjusted life years (DALYs) in China and compare with the international status. Methods: The total number of DALYs, age-standardized DALY rate, and the composition of different subgroups were extracted and described to analyze the time trend in 2000-2019 and the current situation in 2019 for Chinese female breast cancer. The burden of DALYs in 2050 was predicted by Joinpoint using average annual percent change (AAPC). Results: In 2000-2019, the ranking of DALYs caused by female breast cancer in China rose from the fourth to the second in all female cancers. The total DALYs increased by 48.4%, of which the years lived with disability increased from 4.8% to 8.8%. The age-standardized DALY rate only slightly decreased (AAPC=-0.3%; which increased during 2016-2019, AAPC=1.6%). In 2019, the age-standardized DALY rate for breast cancer in China was 278.0/100 000. The DALYs were 2.88 million (accounting for 14.2% of the global burden and 12.1% of all female cancers burden in China), 26.5% of which attributed known risk factors (overweight and obesity were the largest: 0.34 million DALYs, but some common breast cancer risk factors were not available on the platform, such as menstruation and fertility). In 2050, the prediction suggests that the total DALYs caused by female breast cancer in China will reach 3.80 million person-years-5.16 million person-years, increasing 32.1%-79.4% over 2019. From 2000 to 2019, the peak age of DALYs and DALY rate became older, and the DALYs among females aged 65 years and above increased faster than those younger than 65 years (AAPC were 4.8% and 1.3%, respectively). In 2019, females aged 45-74 (the starting age recommended by local guidelines for breast cancer screening) contributed 74.3% of the total DALYs. Conclusions: Over the past 20 years, the age-standardized DALY rate for breast cancer in female populations in China has not changed obviously. Without the continuous expansion of effective intervention and population aging, the burden of DALYs for female breast cancer in China will increase. DALYs for breast cancer attributed leading risk factors were still limited.

Abstract
Prostate cancer is the second most common malignancy in men worldwide. An increasing trend for prostate cancer incidence was observed in China. Enormous studies have been conducted to investigate the association between dietary factors and prostate cancer, however conflicted results were obtained. Red meat, processed meat, and dairy products consumption were reported to be associated with the increased prostate cancer risk, while tomatoes, soybeans and green tea might reduce the risk of prostate cancer occurance. However, no consensus could be reached without strong evidence. Furthermore, further studies are needed to investigate the association between vitamin and mineral supplements and prostate cancer risk. Some studies reported that men with higher dietary inflammatory index scores increased prostate cancer risk. There may be a long susceptible period when dietary factors affect prostate cancer risk, which poses challenges for collecting exposure and the follow-up. Measure bias and detection bias are the main reasons which impair the authenticity of studies on the relationship of dietary factors and prostate cancer risk. Researchers should apply various methods to measure participants' dietary consumption levels and ascertain essential outcomes, such as prostate cancer death. This article reviews updated epidemiological evidences on the association of dietary factors and prostate cancer, aims to benefit future nutritional epidemiology studies focus on the prostate cancer prevention.

Abstract
Objective: To explore the influence of characteristics of green space on blood pressure control. Methods: Hypertensive patients who were managed by community health centers for one year and aged 35 years old and above were selected as the study subjects in Shenzhen. Multi-stage random sampling method was applied to select a representative sample of 1 200 patients. A total of 1 116 valid questionnaires were collected, with a response rate of 93.0%. From November 2019 to January 2020, well-structured questionnaire, physical examination and laboratory biochemical test were applied for information collection among the 1 116 participants. Binary logistic regression model was used to analyze the relationship between characteristics of green space and blood pressure control. Results: The rate of blood pressure control was 67.8%. Results of binary logistic regression analysis showed that after adjusting confounding factors, health supporting elements, such as fitness areas (OR=1.678, 95%CI:1.231-2.288), collective exercise venues(OR=1.373, 95%CI:1.020-1.848), health knowledge promotion areas (OR=1.416, 95%CI: 1.049-1.911) in green space, were significantly correlated with blood pressure control. Green space safetiness (OR=1.010, 95%CI: 1.000-1.019), comfortableness (OR=1.011, 95%CI: 1.001-1.021) and maintenance status (OR=1.011, 95%CI: 1.001-1.021) also played a role. The rate of blood control among patients with exclusive green space was higher than that of patients without exclusive green space (OR=1.333, 95%CI: 1.009-1.762). Conclusion: Health supporting elements, safety, comfort, maintenance of green space and exclusive green space play an important role in blood pressure controlling.

Abstract
Aorto-oesophageal fistula is a rare but fatal disease. Open surgical repair or endotube repair of aorta and oesophagus save patients from circulatory deterioration, major haematemesis and severe infection. Here we present a rare case of an aorto-oesophageal fistula in the right hemi-arch caused by a fish bone treated with an alternative surgical strategy. Total aortic arch repair using the frozen elephant trunk procedure combined with oesophageal repair were performed. No aortic fistula, oesophageal fistula or artificial graft infection occurred in the follow-up.

Methods: We searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, and SinoMed with the term "prostate cancer" "prostate carcinoma" "prostate tumor" "screening" "early detection" "guideline" "recommendation" as keywords. The Appraisal of Guidelines for Research & Evaluation (AGREE) Ⅱ instrument and Reporting Items for Practice Guidelines in Healthcare (RIGHT) were used for critical appraisal. Results: A total of thirteen guidelines were included in this review. Evaluated by the AGREE Ⅱ instrument, ten were considered as A level. Two guidelines scored B level, and one was considered C level. Lowest mean domain scores were for stakeholder involvement (52.1%) and applicability (34.0%). Using the RIGHT checklist, we found that the low reporting quality of the thirteen guidelines could be attributable to incomplete disclosure of evidence (64.6%), funding, declaration and management of interest (44.2%), or other information (46.2%). Conclusions: No guidelines for prostate cancer screening was developed in China. The methodological quality of the guidelines in prostate cancer screening was good, which set a tone for the development of Chinese guidelines. However, all guidelines showed poor reporting quality.

Abstract
Abstract
Background
Inconsistent results have been published that have evaluated the preventive effect of targeted hydration in major adverse renal and cardiac events among patients exposed to contrast agents.
Methods
Online databases were searched up to October, 2019, for randomized controlled trials (RCTs). The primary outcome was the incidence of contrast-induced acute kidney injury (CI-AKI), and the secondary outcomes were all-cause in-hospital mortality, all-cause long-term mortality, requirement for dialysis, acute pulmonary edema and stroke/transient ischemic attack (TIA).
Results
9 high quality trials were identified including 2424 patients. Overall, compared with general hydration, targeted hydration significantly reduced the incidence of CI-AKI by 58% (RR 0.42; 95% CI: 0.33–0.54, p<0.01), the requirement for dialysis by 68% (RR 0.32, 95% CI: 0.17–0.62, p<0.01) and the all-cause long-term mortality by 55% (RR 0.45; 95% CI: 0.26–0.76, p<0.01). The effect on all-cause in-hospital mortality was not statistically significant. The effect on acute pulmonary edema and stroke/TIA also showed no difference between two groups (RR: 0.54, 95% CI: 0.28–1.03, p=0.18; RR: 0.61, 95% CI: 0.14–2.61, p=0.49, respectively). Trial sequential analysis confirmed that an additional 3900 study participants would need to be recruited to demonstrate a statistically significant improvement for all-cause in-hospital mortality.
Conclusions
Targeted hydration likely reduces the incidence of CI-AKI, dialysis and all-cause long-term mortality in patients exposed to contrast agents. However, further independent high-quality RCTs should elucidate the effectiveness and safety of this prophylactic strategy in interventional cardiology.

Abstract
Abstract
Background
The use of high-sensitivity C-reactive protein (hs-CRP) as an inflammation biomarker in predicting long-term mortality remains controversial. We aimed to investigate whether the association of hs-CRP with long-term mortality differs from another inflammation biomarker, lipoprotein(a), in patients undergoing coronary angiography (CAG).
Methods
A total of 2422 patients undergoing CAG were included in the final analysis from a prospective, observational study. We divided them into 4 groups according to hs-CRP level (high ≥4.8 mg/l, low <4.8 mg/l) and lipoprotein(a) level (high ≥17 mg/dl, low <17 mg/dl).
Results
The overall incidence of all-cause long-term mortality was 133/2422 (5.5%). In the high lipoprotein(a) group, after adjusting for LDL-cholesterol concentration (LDL-C), age, sex, smoking status, diabetes mellitus and estimated glomerular filtration rate (eGFR), a high hs-CRP level was an independent predictor of all-cause long-term mortality (hazard ratio: 2.01; 95% CI: 1.13–3.54; p=0.02). In the low lipoprotein(a) group, a similar result was not found (hazard ratio: 1.42; 95% CI: 0.92–2.01; p=0.24).
Conclusions
Our data suggested that the association of hs-CRP with all-cause long-term mortality may differ from lipoprotein(a) levels among patients undergoing CAG. In addition to hs-CRP, a high lipoprotein(a) level might be a simultaneous intervention target for improving long-term prognosis in the future.

Abstract
Abstract
Background
Administration of iodinated contrast is common but may be associated with contrast-induced acute kidney injury (CI-AKI), particularly in at-risk patients. There is no recent systematic review of potentially modifiable risk factors.
Methods
We searched MEDLINE, Embase and the Cochrane Database of Systematic Reviews (to 30 th June 2019) for observational studies assessing risk factors associated with CI-AKI. Twelve potentially modifiable risk factors were finally included in this thematic review and meta-analysis. Random or fixed meta-analysis was performed to derive the adjusted odds ratio (aOR), and the population attributable risk (PAR) was calculated for each risk factor globally and by region.
Findings
We included 157 studies (2,297,863 participants). The global incidence of CI-AKI was 5.4%. The potentially modifiable risk factors included high contrast volume (PAR 33%), eight cardiovascular risk factors (diuretic use, multivessel coronary artery disease, acute coronary syndrome, hypertension, hypotension, heart failure, reduced left ventricular ejection fraction and intra-aortic balloon pump use) (combined PAR 76.2%) and three noncardiovascular risk factors (renal dysfunction, diabetes mellitus and anaemia) (combined PAR 47.4%) with geographical differences.

Abstract
Abstract
Background
Right ventricular (RV) function remains poorly recognized for its value in predicting cardiovascular events at a population level. Cardiovascular Magnetic Resonance (CMR) imaging is the gold standard for RV assessment.
Purpose
To define the independent prognostic value of RVEF for the prediction of major adverse cardiovascular events (MACE) as primary outcome in patients with known or suspected cardiovascular disease.
Methods
Data was obtained from the Cardiovascular Imaging Registry of Calgary (CIROC). Patients underwent standardized CMR imaging protocols and analysis. Clinical events were identified from administrative data.
Results
7,131 patients were included. 870 primary outcome events occurred over 2.5 years follow-up. RVEF provided equivalent predictive utility versus LVEF (Table 1). There was an increase in events with worsening severity of RVEF (Figure 1), with a significant “threshold-effect” at an RVEF of 40%.
Conclusions
RVEF is a strong and independent predictor of MACE at a population level.

Abstract
Abstract
Background
Patients with congestive heart failure (CHF) are vulnerable to contrast-induced acute kidney injury (CI-AKI), but few prediction models are currently available.
Objectives
We aimed to establish a simple nomogram for CI-AKI risk assessment for patients with CHF undergoing coronary angiography.
Methods
A total of 1876 consecutive patients with CHF (defined as New York Heart Association functional class II-IV or Killip class II-IV) were enrolled and randomly (2:1) assigned to a development cohort and a validation cohort. The endpoint was CI-AKI defined as serum creatinine elevation of ≥0.3 mg/dL or 50% from baseline within the first 48–72 hours following the procedure. Predictors for the nomogram were selected by multivariable logistic regression with a stepwise approach. The discriminative power was assessed using the area under the receiver operating characteristic (ROC) curve and was compared with the classic Mehran score in the validation cohort. Calibration was assessed using the Hosmer–Lemeshow test and 1000 bootstrap samples.
Results
The incidence of CI-AKI was 9.06% (n=170) in the total sample, 8.64% (n=109) in the development cohort and 9.92% (n=61) in the validation cohort (p=0.367). The simple nomogram including four predictors (age, intra-aortic balloon pump, acute myocardial infarction and chronic kidney disease) demonstrated a similar predictive power as the Mehran score (area under the curve: 0.80 vs 0.75, p=0.061), as well as a well-fitted calibration curve.
Conclusions
The present simple nomogram including four predictors is a simple and reliable tool to identify CHF patients at risk of CI-AKI, whereas further external validations are needed.

Abstract
Abstract
Background
Cardiovascular diseases remain the leading cause of morbidity worldwide and impose the highest economic burden among noncommunicable diseases. Much of these costs are related to hospitalizations for adverse cardiovascular events, which may be reduced by targeted management of high-risk patients. Cardiac markers derived from CMR imaging have been shown to be strong independent predictors of prognosis within specific cohorts. However, its capacity to broadly contribute to risk models aimed at predicting incident cardiac hospitalization has not been demonstrated.
Purpose
Using a large clinical outcomes registry of patients clinically referred for CMR, develop and validate a nomogram for prediction of cardiovascular hospital admission.
Methods
A total of 7127 consecutive patients were prospectively recruited between 02/2015 and 07/2019. All patients completed standardized health questionnaires and CMR imaging protocols. A nomogram was developed for prediction of cardiovascular hospitalization, inclusive of admission for heart failure, MI, cardiac arrest, heart transplant, LVAD implantation, or stroke. The risk model was derived from 80% (n=5702) of the cohort using Cox modelling that included CMR, medication, laboratory, and patient-reported health variables. Model validation was assessed by discrimination and calibration procedures applied to the remaining 20% of patients (n=1425). A minimum follow-up of six months was mandated.
Results
The derivation cohort was comprised of 38% females with a median age of 56 (IQR 44–65) years. During a median follow-up of 934 days, 514 (9.0%) events occurred. The validation cohort was similarly comprised of 37% females with a median age of 57 (IQR 44–66) years. During a median follow-up of 970 days, 142 (10.0%) events occurred. Numerous CMR parameters were significantly different between those experiencing versus not experiencing the primary composite outcome, including: LVEF (44% vs 59%, p<0.0001), RVEF (52% vs 55%, p<0.0001), LV mass (65g/m2 vs 56g/m2, p<0.0001), and LA volume (43mL/m2 vs 34mL/m2, p<0.0001). These and other CMR-derived characteristics were independently predictive of the composite outcome by univariate modelling (Figure 1A). An eight-variable nomogram (Figure 1B) was developed using a stepwise multivariate model that exhibited high discrimination in both the derivation and validation cohorts (C-index 0.81 and 0.83, respectively). Continuous model calibration curves indicated satisfactory external performance. The model was able to discriminate risk of hospitalization at 1-year with a dynamic range of 20–99%.
Conclusion
Using data available at time of CMR imaging, we derived and validated a Cox-based nomogram that offers robust prediction of future cardiovascular admissions. This tool may provide value for the identification of patients who may benefit from targeted surveillance and management strategies, and may offer a foundation for improved patient-specific cost modelling.

Abstract
OBJECTIVE Ovarian cancer is one of the most common causes of cancer-related deaths in women. Many studies show that dysregulated gene expression plays a key role in tumorigenesis and development. Therefore, a comprehensive understanding of ovarian serous cystadenocarcinoma survival prognosis is needed. PATIENTS AND METHODS A large number of high-dimensional RNA-sequencing files and clinical datasets collected from the Genomic Data Commons Data Portal were utilized to identify novel potential biomarkers for determining the prognosis of patients with ovarian serous cystadenocarcinoma (OVSC). We adopted a new strategy to identify these biomarkers by integrating co-expression network analysis and the Kaplan-Meier estimation with a non-parametric bootstrapping procedure. RESULTS Functional enrichment analysis of gene modules of interest revealed several dysregulated genes in OVSC, suggesting a close relationship between hormones and angiogenesis. In combination with this comprehensive approach, 14 genes, including ABCA10, DCX, LRRC30, ALX4, DKK4, SGCZ, ANKS4B, FHL5, SPRR2F, CHRNG, GABRR1, STMN2, CRHBP, and GSTM5, were shown to serve as candidate biomarkers for predicting the prognosis of patients with OVSC. CONCLUSIONS The current study identified several valuable prognostic biomarkers and several potential therapeutic targets for treating OVSC.

Abstract
OBJECTIVE The aberrant expression of long noncoding RNAs (lncRNAs) is involved in the molecular regulation of non-small cell lung cancer (NSCLC). This study aims to investigate the biological interaction of lnc-FAM201A and its downstream factors and their impacts on the radiotherapy response of NSCLC. PATIENTS AND METHODS Quantitative Polymerase Chain Reaction (qPCR) was used to determine the expression of FAM201A in NSCLC tissues. The Chi-square tests explored the association between FAM201A level and the poor clinicopathological characteristics (including radioresistance) of NSCLC. Univariate and multivariate Cox proportional hazards regression analyses were used to evaluate various prognostic factors for overall survival (OS). The effect of FAM201A on OS was tested by the log-rank test. A549/SK-MES-1 cell lines transfected with short hairpin RNA (shRNA) were used to verify the promoting effects of FAM201A on radiotherapy resistance in vitro and in vivo. Cell apoptosis (analyzed by flow cytometry), cell proliferation (determined by Cell Counting Kit-8), and mice xenograft models were performed to confirm the results. The downstream targets of FAM201A were predicted by bioinformatics tools. Additionally, the Dual-luciferase reporter assay, qPCR, and Western blotting were performed to confirm their interaction. RESULTS FAM201A was significantly upregulated in tissues obtained from NSCLC patients resistant to radiotherapy. Increased FAM201A expression was strongly associated with radioresistance and inferior survival in NSCLC, as demonstrated by clinical data. The silence of FAM201A could inhibit cell proliferation and further cell apoptosis of NSCLC cells under X-ray irradiation both in vitro and in vivo. Moreover, by competitively targeting miR-370, FAM201A elevated the epidermal growth factor receptor (EGFR) and the hypoxia-inducible factor 1alpha (HIF-1α) levels. After FAM201A knockdown, EGFR and HIF-1α were repressed with enhanced radiosensitivity. CONCLUSIONS The interference of FAM201A impairs its suppression of miR-370, resulting in the upregulation of EGFR and HIF-1α and enhancement of radiosensitivity in NSCLC patients. Collectively, our results indicated that this regulatory axis might serve as a potential therapeutic target to increase the sensitivity of radiotherapy in NSCLC patients.

Abstract
Enterococcus faecalis is the dominant pathogen for persistent periapical periodontitis. The chlorhexidine (CHX) is used as conversional irrigation agents during endodontic root canal therapy. It was reported that the antisense walR RNA (ASwalR) suppressed the biofilm organization. The aim of this study was to investigate the antimicrobial effects of novel graphene oxide (GO)-polyethylenimine (PEI)-based antisense walR (ASwalR) on the inhibition of E. faecalis biofilm and its susceptibility to chlorhexidine. The recombinant ASwalR plasmids were modified with a gene encoding enhanced green fluorescent protein (ASwalR-eGFP) as a reporter gene so that the transformation efficiency could be evaluated by the fluorescence intensity. The GO-PEI-based ASwalR vector transformation strategy was developed to be transformed into E. faecalis and to over-produce ASwalR in biofilms. Colony forming units (CFU) and confocal laser scanning microscopy were used to investigate whether the antibacterial properties of antisense walR interference strategy sensitize E. faecalis biofilm to the CHX. The results indicated that overexpression of ASwalR by GO-PEI-based transformation strategy could inhibit biofilm formation, decrease the EPS synthesis and increase the susceptibility of E. faecalis biofilms to CHX. Our reports demonstrated that antisense walR RNA will be a supplementary strategy in treating E. faecalis with irrigation agents.

Abstract
OBJECTIVE To understand the status of chronic filariasis patients in Jiangxi Province in 2018, so as to provide insights into the follow-up care of the patients. METHODS In 2018, a case follow-up study was conducted in all registered patients with chronic filariasis in previously endemic areas of Jiangxi Province, and a clue investigation was done for identifying the missing patients. In addition, the data of caring sites for chronic filarisis patients were collected and analyzed in the province. RESULTS A total of 802 chronic filariasis patients were identified in 56 counties (districts) of Jiangxi Province in 2018. The patients had a male/female ratio of 1∶1, and 85.41% had ages of over 70 years. There were 58.60%, 93.89%, 17.21% and 3.62% of chronic filariasis patients with lymphangitis, lymphedema/elephantiasis, chyluria and hydrocele, respectively. A total of 273 caring sites were assigned in 56 counties (districts) of Jiangxi Province, and 306 caring activities were carried out in 2018. CONCLUSIONS The number of chronic filariasis patients has significantly decreased in Jiangxi Province; however, the care remains to be intensified for chronic filariasis patients.

Abstract
Two industrial polycarboxylate superplasticizer samples have been selected to be used within the Priority Program 2005 of the German Research Foundation (DFG SPP 2005). The PCE polymers were characterized via Size Exclusion Chromatography (SEC) to determine their molar masses (Mw, Mn), the polydispersity index (PDI) and the conversion rate which indicates the incorporation of the macromonomer into the polymer. The anionic charge amount of the PCE samples was assessed via charge titration employing a cationic polymer. Furthermore, the cement dispersing properties of the PCE polymers were captured via 'mini slump' tests so as to assess their ability to fluidize CEM I 42.5 R and CEM III/A 42.5 N samples, respectively. Also, interaction between the PCEs and the surface of the cements was investigated via adsorption and zeta potential measurements of aqueous cement suspensions. The results shall be used for the ongoing research within the Priority Program.

Abstract
Background:Flare, relapse from status of treat-to-target (T2T, DAS28<=3.2), is hard predicted. We try to make it predictable by applying machine learning to a database from smart system of disease management (SSDM). SSDM is an interactive mobile disease management APPs.Objectives:To develop and validate machine learning algorithms for flare prediction in RA.Methods:Patients were trained using SSDM and input their data, including demographic, comorbidities (COMBs), lab test, medications and monthly self-assessments, including DAS28, HAQ, SF-36, Hospital Anxiety and Depression Scale (HADS). The data was uploaded to cloud and synchronized to the mobile of authorized rheumatologists. The COMBs were by ICD-9, and medications were listed as cDMARDs, Bio (BioDMARDs), NSAIDs, Steroid, FS (food supplements), MC (medicine for COMBs), TCM (Traditional Chinese Medicine), and combinations.Results:From Jan of 2015 to Jan of 2020, 8811 RA patients, 85% female and 15% male, used to reach T2T. 4556 were flare-free and 4255 suffering at least one flare. The average 160 attributes were extracted from each flare-free patient at time of reaching T2T, and each flare patients at time of 3 months before the flare. Patients were randomly assigned as model setup (training) group (70%) and validation (testing) group30%.For training, data were processed using Python with statistical analyses in R. In R, random forests were implemented. Logistic regression via glm in base R. The random forest comprises a set of decision trees. “Splits” in the decision trees reflect binary (i.e., yes/no) respect to attributors. Bootstrapping was used to assess, quantify, and adjust for model optimism. Model performance was evaluated using AUC, precision and recall metrics. Brier scores for accuracy of probabilistic predictions ranged from 0 to 1 (0 is perfect discrimination).The testing showed model performance for prediction windows are 0.78 for AUC (95% CI), 0.71 for Recall (sensitivity), 0.195 for Brier score, and 0.68 for precision (true positive 893, false positive 417, false negative 367, true negative 966).Based on weighing in the random forest, the top 10 pro-flare attributes were CRP, swollen joint count (SJC), tender joint count (TJC), HAQ, DAS28, morning stiffness, gout, MCTD, OA, duration; while top 10 anti-flare attributes were cDMARDs+Bio, cDMARDs+steroid+NSAIDs, stable on HAQ, on morning stiffness, on SJC, medicine on COMBs, cDMARDs+TCM, stable on TJC, on ESR, income at 100-200k (Fig.1). The top weighing COMBs for pro-flaring were gout (0.81), MRD (0.75), OA (0.56), AS (0.48). The monotherapies with either Bio or NSAIDs, or steroid, or TCM was pro-flare; while with cDMARDs was anti-flare (-0.21).Figure 1.Conclusion:The attempt to develop a machine learning algorithm for RA flare prediction is successful. The discrimination was acceptable. The attributes of both pro-flare and anti-flare are identified, which may inspire the proactive intervention.Acknowledgments:SSDM was developed by Shanghai Gothic Internet Technology Co., Ltd.Disclosure of Interests:None declared

Abstract
Direct measurements of the adiabatic temperature change (ΔTad) in Gd and Mn1.15Fe0.8P0.5Si0.5C0.05 are made using a homemade adiabatic magnetocalorimeter at 260-360 K and 0-7 T. The system uses a servo motor to drive the samples into and out of the magnetic field under a vacuum environment provided by the Physical Property Measurement System (PPMS). The peak values of ΔTad for Gd and Mn1.15Fe0.8P0.5Si0.5C0.05 at 7 T are 8.71 K and 6.41 K at ambient temperatures of 303 K and 317 K, respectively. Based on the theory model, it is found that ΔTad of Gd depends on the 2/3 exponential function of magnetic field H (ΔTad ∝ H2/3), whereas the Mn1.15Fe0.8P0.5Si0.5C0.05 compound follows the power law of ΔTad ∝ H0.66-1.04 due to the first order magnetic transitions. Furthermore, using the constructed experimental instrument, the adiabatic temperature change in different magnetic materials, including materials with first/second order magnetic transition and blocks, flakes, or powders, can be directly measured under large magnetic fields and wide temperature spans.

Abstract
Dihydroquercetin (DHQ) is a flavonoid compound known for its anti-oxidant effects. Oxidative stress plays a dominant role in regulating the pathways associated with systemic inflammatory immune activation during endotoxemia. Whether and how DHQ regulates inflammatory responses in endotoxemia remains elusive. Here we show DHQ pretreatment effectively reduced the Ten-day mortality in bacterial endotoxin lipopolyssacharide (LPS)-challenged mice, suppressing LPS-induced inflammatory responses reflected by impaired production of tumor necrosis factor α (TNF-α) and interleukin-6 (IL-6) in the serum of mice. In Raw 264.7 cells, DHQ pretreatment significantly inhibited the transcriptional upregulation of TNF-α, interferon-γ (IFN-γ), interleukin-10 (IL-10) and toll-like receptor 4 (TLR-4) after LPS stimulation. Additionally, knockdown of heme oxygenase-1 (HO-1), one of the most important DHQ induced antioxidant genes, cancelled the inhibition of DHQ treatment on LPS induced TNF-α, IFN-γ production. Nuclear factor erythroid 2-related factor 2 (Nrf2) expression and AMP-activated protein kinase (AMPK) phosphorylation were both enhanced by DHQ in Raw 264.7 cells, indicating a DHQ induced AMPK/Nrf2/HO-1 signal axis. In conclusion, DHQ pretreatment could protect mice against the inflammation and mortality associated with endotoxemia.
