Abstract
Advanced glycation end products (AGEs), derived from the non-enzymatic glycation reaction, are defined as glycotoxins in various diseases including aging, diabetes and kidney injury. Exploring AGEs as potential biomarkers for these diseases holds paramount significance. Nevertheless, the high chemical structural similarity and great heterogeneity among AGEs present a formidable challenge when it comes to the comprehensive, simultaneous, and accurate detection of multiple AGEs in biological samples. In this study, an UPLC/MS/MS method for simultaneous quantification of 20 free AGEs in human serum was firstly established and applied to quantification of clinical samples from individuals with kidney injury. Simple sample preparation method through protein precipitation without derivatization was used. Method performances including imprecision, accuracy, sensitivity, linearity, and carryover were systematically validated. Intra- and inter- imprecision of 20 free AGEs were 1.93-5.94 % and 2.30-8.55 %, respectively. The method accuracy was confirmed with good recoveries ranging from 96.40 % to 103.25 %. The LOD and LOQ were 0.1-3.13 ng/mL and 0.5-6.25 ng/mL, respectively. Additionally, the 20 free AGEs displayed excellent linearity (R2 >0.9974) across a wide linear range (1.56-400 ng/mL). Finally, through simultaneous quantitation of 20 Free AGEs in 100 participants including kidney injury patient and healthy controls, we identified six free AGEs, including N6-carboxyethyl-L-arginine (CEA), N6-carboxymethyl-L-lysine (CML), methylglyoxal-derived hydroimidazolones (MG-H), N6-formyl-lysine, N6-carboxymethyl-L-arginine (CMA), and glyoxal-derived hydroimidazolone (G-H), could well distinguish kidney injury patients and healthy individuals. Among them, the levels of four free AGEs including CML, CEA, MG-H, and G-H strongly correlate with traditionally clinical markers of kidney disease. The high area under the curve (AUC) values (AUC=0.965) in receiver operating characteristic (ROC) curve indicated that these four free AGEs can be served as combined diagnostic biomarkers for the diagnosis of kidney disease.

Abstract
Despite the great progress in the treatment of colorectal cancer (CRC), the current standard treatment protocols still have many limitations, and there is an urgent need for more effective biomarkers for personalized patient treatment. Circulating tumor DNA (ctDNA), as a dynamic, non-invasive liquid biopsy approach, overcomes the limitations of tissue biopsy in detecting tumor heterogeneity and molecular evolution. Current evidence from several studies suggests that ctDNA shows great promise in stratifying recurrence risk, guiding treatment decisions, and monitoring early recurrence. In addition, ctDNA can improve the efficiency of clinical research and drug development. However, the lack of standardisation of pre-ctDNA test variables and analysis procedures and the high technical costs limit its promotion and development. In this review, we summarize the available evidence on ctDNA in the clinical management of CRC and present its limitations and strategies for improvement.

Abstract
1. Infectious injury caused by lipopolysaccharide (LPS), a metabolite of gram-negative bacteria, can induce stress responses in animals and is a significant cause of morbidity and mortality in young birds. The purpose of this study was to investigate the effects of dietary supplementation with oleanolic acid (OA) on acute liver injury in broiler chickens challenged with LPS.2. In total, 120 broiler chickens were randomly divided into six groups and fed a basal diet containing 0, 50, 100, or 200 mg/kg OA or 100 mg/kg aureomycin. On d 15, broiler chickens were injected with either LPS or an equivalent volume of normal saline. Six hours after LPS injection, two broiler chicks were randomly selected for sampling in each replicate.3. The results indicated that dietary aureomycin was ineffective in alleviating LSP-associated liver injury, but protected broiler chickens from LPS-induced liver damage. This promoted a significant reduction in the levels of malondialdehyde and an increase in the levels of superoxide dismutase in liver. In addition, OA was found to cause significant reductions in the relative expression of IL-1β, IL-6, and TNF-α in broiler liver tissues, whereas the relative expression of IL-10 was significantly increased.4. In conclusion, oleanolic acid can alleviate oxidative stress and injury in the livers of broiler chickens induced by lipopolysaccharide. Consequently, oleanolic acid has potential utility as a novel anti-inflammatory and antioxidant feed additive.

Abstract
Objective: To investigate the efficacy of strategies for minimizing small bowel resection during surgery for pelvic radiation-induced terminal small intestinal stenosis in preventing postoperative complications such as anastomotic leakage and short bowel syndrome. Methods: This was a retrospective cohort study. There are two subtypes of chronic radiation enteritis (CRE) with combined intestinal stenosis and intestinal obstruction: (1) Type I: terminal ileal lesions with a normal ileal segment of 2-20 cm between the ileal lesion and ileocecal junction; and (2) Type II: the lesion is located in the small bowel at a distance from the ileocecal region, usually accompanied by extensive damage to the bowel segments outside the lesion. The indications for minimal bowel resection are as follows: (1) diagnosis of Type I small bowel CRE; (2) absence of radiological evidence of rectosigmoid damage; and (3) absence of colonic obstruction. The contraindications are: (1) stenotic, penetrating lesions of the distal cecum; (2) emergency surgery; (3) recurrence of malignant tumor or history of radiotherapy for recurrent malignant tumor; (4) interval between radiotherapy and surgery <6 months; and (5) history of preoperative small bowel resection or abdominal chemotherapy. Case data of 40 patients with Type I CRE who met the above criteria and had undergone minimal bowel resection between April 2017 and December 2019 were retrospectively analyzed (minimal bowel resection group; including 13 patients from Jinling Hospital, 16 from the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, and 11 from the Affiliated Hospital of Xuzhou Medical University). Forty patients with Type I CRE who had undergone resection of intestinal stenosis lesions and the ileocecal region between October 2015 and March 2017 were included as historical controls (conventional resection group; all from Jinling Hospital). The specific strategy for minimal bowel resection was one-stage partial ileal resection+ileo anastomosis+protective small bowel stoma. In contrast, conventional resection comprised ileocecal resection+ileocecal-ascending colon anastomosis. Postoperative complications, intraoperative and postoperative recovery, and changes in postoperative quality of life were analyzed in both groups. The severity of postoperative complications was assessed by Clavien-Dindo and the Comprehensive Complication Index (CCI). Karnofsky performance scores (KPS) were used to evaluate the quality of life of patients in the two groups preoperatively and postoperatively. The higher the KPS score, the better the quality of life. Results: Baseline patient characteristics did not differ significantly between the two groups (P>0.05). Compared with the conventional resection group, the length of small bowel resected in the minimal bowel resection group (51 [20-200] cm vs. 91 [60-200] cm, Z=5.653, P<0.001), duration of postoperative total enteral nutrition [9 (3-18) days vs. 12 (4-50) days, Z=2.172, P=0.030], and duration of postoperative hospital stay [17 (9-24) days vs 29 (13-57) days, Z=6.424, P<0.001] were shorter; all of these differences are statistically significant. The overall incidence of postoperative complications was lower in the minimal bowel resection group than in the conventional resection group [20.0% (8/40) vs. 70.0% (28/40), χ2=19.967, P<0.001], These comprised short bowel syndrome [5.0% (2/40) vs. 25.0% (10/40), χ2=6.274, P=0.012], anastomotic leakage or fistula [2.5% (1/40) vs. 22.5% (9/40), χ2=7.314, P=0.014], and pleural effusion [7.5% (3/40) vs. 25.0% (10/40), χ2=4.500, P=0.034], all of which occurred less often in the minimal bowel resection than conventional resection group. The CCI index was also lower in the minimal bowel resection group than in the conventional resection group [CCI>40: 2.5% (1/40) vs. 12.5% (5/40), Z=18.451, P<0.001]. KPS scores were higher in the minimal bowel resection group 1 and 3 months postoperatively than they had been 1 day preoperatively (79.9±4.7 vs. 75.3±4.1, 86.2±4.8 vs. 75.3±4.1, both P<0.05). In the minimal bowel resection group, seven patients were satisfied with their current quality of life and refused to undergo stoma reduction at follow-up and one deferred stoma reduction because of rectal bleeding. The remaining 32 patients underwent stoma reduction 3 to 12 months after surgery, 26 of whom underwent ileo-cecal anastomosis. The remaining six underwent resection of the stoma and anastomosis of the ileum to the ascending colon. Conclusions: The strategy of minimal small bowel resection in patients with radiation-induced bowel injuries reduces the length of resected small bowel, decreases the risk and severity of postoperative complications, and is associated with a better prognosis and quality of life than conventional resection.

Abstract
PURPOSE/OBJECTIVE(S) Coronary artery calcium (CAC) score is an important predictive imaging marker of cardiovascular disease (CVD). While studies have found positive association between CAC score and cardiac toxicity in irradiated lung and breast cancer patients, there are no studies assessing CAC scores in esophageal cancer (EC). While a cardiac-gated CT is required for standard Agatston CAC score, visual assessment of CAC via ordinal scoring on non-gated CT has shown good concordance with Agatston score. In this study, we sought to examine whether visual assessment of CAC, measured on standard of care, non-contrast chest CT, predicts the development of adverse cardiovascular events (ACVE) in irradiated EC patients. MATERIALS/METHODS This is a single institution retrospective study of EC patients treated with RT from 2010-2021. We included patients with available PET/CT at diagnosis or chest CT simulation scan without contrast, and excluded those with history of percutaneous coronary intervention, coronary bypass surgery, or prior thoracic RT. Pre-treatment characteristics, clinical factors, and grade ≥ 3 (G3+) adverse cardiovascular events (ACVE) (CTCAEv5.0) were evaluated. Visual assessment of CAC was performed using ordinal method (CAC scored from 0 to 12), by a thoracic radiologist. Fine and Gray regression was used to compute hazard ratios for time to first ACVE. Univariate analyses using Cox proportional hazards were used for overall survival (OS). ACVEs were recorded from start of oncologic treatment and OS calculated after completion of RT. RESULTS A total of 118 patients were analyzed with a median follow-up of 16 months. Median age was 67 years, 65% male, 43% white, 59% with EC of distal esophagus, and 59% had squamous cell carcinoma. Median mean heart dose was 21.93 Gy (range 0.15-36.94). 24% developed G3+ ACVEs: atrial fibrillation 9%, stroke 6%, heart failure 4%, pulmonary embolism 4%, pericardial effusion 3%, myocardial infarction 2%, heart block 2%, and cardiac death 1%. On univariate analyses, CAC >1 vs. CAC ≤ 1 trended towards increased risk of ACVE (HR = 1.95, 95% CI = 0.89-4.26; p = 0.094), however it is not predictive of OS (HR = 1.31, 95% CI = 0.75-2.30; p = 0.343). Proportion of patients with ACVEs was greater in CAC>1 group (Table). When compared to patients with CAC ≤ 1, those with CAC >1 were older (median age 62 vs 72 years, p = 0.0015), less likely to be never smokers (38% vs 30%, p = 0.0437), and more likely to have hypertension (43% vs 64%, p = 0.0197), and hyperlipidemia (30% vs 47%, p = 0.0557). CONCLUSION This is the first study to investigate the relationship between CAC score and ACVEs in EC. While the study was underpowered (likely due to low rates of recorded ACVEs), to detect a significant association between CAC score and ACVEs, there was a trend towards increased risk of ACVEs in patients with a CAC score >1 by visual ordinal scoring. Further prospective evaluation with a larger cohort is warranted.

Abstract
Objective: To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test. Methods: This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ (2) test. A kappa test was used to compare the consistency between groups. Results: After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea (Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences (P < 0.001). Conclusion: The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Abstract
BACKGROUND Electroencephalogram (EEG) has emerged as a non-invasive tool to detect the aberrant neuronal activity related to different stages of Alzheimer's disease (AD). However, the effectiveness of EEG in the precise diagnosis and assessment of AD and its preclinical stage, amnestic mild cognitive impairment (MCI), has yet to be fully elucidated. In this study, we aimed to identify key EEG biomarkers that are effective in distinguishing patients at the early stage of AD and monitoring the progression of AD. METHODS A total of 890 participants, including 189 patients with MCI, 330 patients with AD, 125 patients with other dementias (frontotemporal dementia, dementia with Lewy bodies, and vascular cognitive impairment), and 246 healthy controls (HC) were enrolled. Biomarkers were extracted from resting-state EEG recordings for a three-level classification of HC, MCI, and AD. The optimal EEG biomarkers were then identified based on the classification performance. Random forest regression was used to train a series of models by combining participants' EEG biomarkers, demographic information (i.e., sex, age), CSF biomarkers, and APOE phenotype for assessing the disease progression and individual's cognitive function. RESULTS The identified EEG biomarkers achieved over 70% accuracy in the three-level classification of HC, MCI, and AD. Among all six groups, the most prominent effects of AD-linked neurodegeneration on EEG metrics were localized at parieto-occipital regions. In the cross-validation predictive analyses, the optimal EEG features were more effective than the CSF + APOE biomarkers in predicting the age of onset and disease course, whereas the combination of EEG + CSF + APOE measures achieved the best performance for all targets of prediction. CONCLUSIONS Our study indicates that EEG can be used as a useful screening tool for the diagnosis and disease progression evaluation of MCI and AD.

Abstract
Objective: To investigate the epidemiological characteristics of sudden death on job among workers in the large oil field, and to provide scientific basis for dealing with such incidents. Methods: In April 2021, the medical records of employees who died in a large oilfield from 2014 to 2020, and the occupational health examination data in the first year of life were collected, and 85 employees who died suddenly on duty were included in the study. According to whether the employees are exposed to the occupational disease hazards, they are divided into the injured type of work (66 persons) and the non injured type of work (19 persons) . The characteristics of the clinical data of the sudden death employees are analyzed retrospectively. The gender, age, length of service, type of work, distribution of causes of sudden death of the cases are analyzed. The detection of abnormalities in various occupational health examination indicators is analyzed. The chi square test is used to analyze the distribution of the types of work, length of service and abnormal physical examination indicators. Results: Among the 85 employees who died suddenly on duty, the ratio of men and women was 16∶1. The proportion of sudden death among employees aged 40 to 50 years was the highest (54.12%, 46/85) , which was mainly the first-line workers in the affected departments (43.53%, 37/85) and those with 20-30 years of service (57.64%, 49/85) . The main cause of sudden death was cardiogenic sudden death (78.82%, 67/85) . There were statistically significant differences in abnormal rates of blood pressure and blood glucose among workers of different types of work (χ(2)=7.24, 24.22, P<0.05) , and there were statistically significant differences in abnormal rates of blood lipid and blood glucose among workers of different ages of service (χ(2)=12.37, 31.44, P<0.05) Conclusion: Higher risks of sudden death on job are male, older than 40 years old, front-line workers in disaster receiving departments, worked for more than 30 years, and have abnormal cardiovascular indicators. Workers with these high risks are the major target population for the prevention and treatment of sudden death on the job. It's necessary to supervise enterprises to implement protective measures against risk factors, and to strengthen health education and reduce the incidence of cardiovascular and cerebrovascular diseases, in order to reduce the occurrence rate of sudden death in oilfield workers.

Abstract
PurposeThe effect of sensorimotor stripping on neuroplasticity and motor imagery capacity is unknown, and the physiological mechanisms of post-amputation phantom limb pain (PLP) illness remain to be investigated.Materials and methodsIn this study, an electroencephalogram (EEG)-based event-related (de)synchronization (ERD/ERS) analysis was conducted using a bilateral lower limb motor imagery (MI) paradigm. The differences in the execution of motor imagery tasks between left lower limb amputations and healthy controls were explored, and a correlation analysis was calculated between level of phantom limb pain and ERD/ERS.ResultsThe multiple frequency bands showed a significant ERD phenomenon when the healthy control group performed the motor imagery task, whereas amputees showed significant ERS phenomena in mu band. Phantom limb pain in amputees was negatively correlated with bilateral sensorimotor areas electrode powers.ConclusionSensorimotor abnormalities reduce neural activity in the sensorimotor cortex, while the motor imagination of the intact limb is diminished. In addition, phantom limb pain may lead to over-activation of sensorimotor areas, affecting bilateral sensorimotor area remodeling.

Abstract
Both forward and backward working memory span tasks have been used in cognitive training, but no study has been conducted to test whether the two types of trainings are equally effective. Based on data from a randomized controlled trial, this study (N = 60 healthy college students) tested the effects of backward span training, forward span training, and no intervention. Event-related potential (ERP) signals were recorded at the pre-, mid-, and post-tests while the subjects were performing a distractor version of the change detection task, which included three conditions (2 targets and 0 distractor [2T0D]; 4 targets and 0 distractor [4T0D]; and 2 targets and 2 distractors [2T2D]). Behavioral data were collected from two additional tasks: a multi-object version of the change detection task, and a suppress task. Compared to no intervention, both forward and backward span trainings led to significantly greater improvement in working memory maintenance, based on indices from both behavioral (Kmax) and ERP data (CDA_2T0D and CDA_4T0D). Backward span training also improved interference control based on the ERP data (CDA_filtering efficiency) to a greater extent than did forward span training and no intervention, but the three groups did not differ in terms of behavioral indices of interference control. These results have potential implications for optimizing the current cognitive training on working memory.

Abstract
Objective: To compare the efficacy of off-pump coronary artery bypass grafting (CABG) or CABG plus mitral valve plasty (MVP) in patients with coronary heart disease complicated with moderate ischemic mitral insufficiency. Methods: The clinical data of 1 050 patients with coronary heart disease complicated with moderate ischemic mitral insufficiency who underwent surgical procedures from January 2009 to December 2020 were analyzed retrospectively. There were 733 males and 317 females, aging (63.3±9.0) years (range: 31 to 83 years). Patients were divided into CABG+MVP group and CABG group according to surgical methods, and the two groups of patients were matched for 1∶4 by the propensity score matching method. There were 107 patients in the CABG+MVP group and 406 patients in the CABG group after matching. The t test, Mann-Whitney U test, χ2 test, Fisher's exact probability method and repeated measures anova were used to compare the surgical outcomes and overall survival in the two groups. Results: There were no significant differences in perioperative death and postoperative complications between the two groups (all P>0.05). Compared with CABG group, CABG+MVP group had longer operation time ((5.6±1.2) hours vs. (4.2±1.0) hours, t=11.528, P<0.01), ICU stay(M(IQR))(43.0(47.3) hours vs. 25.0(33.6) hours, Z=2.483, P=0.013), and postoperative hospital stay (8(4) days vs. 7(5) days, Z=2.143, P=0.032). The amount of erythrocyte and platelet used in CABG+MVP group was significantly increased (2.0(6.5) U vs. 0(2.0) U, Z=7.084, P<0.01; 0(0.5) U vs. 0(0) U, Z=5.210, P<0.01). A total of 463 cases (93.9%) were followed up. Median follow-up was 32(31) months (range: 3 to 105 months). There was no significant difference in overall survival and no major adverse cardic and cerebrovascular events survival between CABG group and CABG+MVP group (P=0.196,P=0.305). Echocardiography showed that there was no significant difference in ejection fraction left ventricular end-diastolic diameter between the two groups (F=0.322, P=0.571; F=0.681, P=0.410). However, CABG+MVP improved mitral regurgitation better than CABG (F=160.222, P<0.01). Conclusions: For patients with coronary heart disease with moderate ischemic mitral insufficiency, the rates of all-cause mortality and major adverse cardiac and cerebrovascular events are similar between the two surgeries. Although CABG+MVP improves mitral regurgitation better than CABG, it increases the duration of surgery, ICU stay, postoperative hospital stay, and blood transfusion requirement.

Abstract
Objective To run a systematic review and meta-analysis of related studies on body mass index (BMI) and the risk of death among pulmonary hypertension (PH) patients, as well as, to shed light on the shape and strength of the dose-response association. Methods Studies published up to Jun 2021 in scientific databases such as Scopus, and PubMed as well as Google Scholar were searched. Cohort studies that reported risk estimates for at least two categories of BMI or per certain increase in BMI in relation to mortality in PH patients were included. Summary relative risks were determined with random effects models. Non-linear relationship was discovered with dose-response analysis. Results All in all, 15 cohort studies were selected. The number of participants was 127,215 out of which 73,999 were reported dead. The summary RR for mortality per a 5-unit increment in BMI was 0.83 (95% confidence interval 0.77–0.89; I2 = 75.6%, n = 9) among PH patients. There was a non-linear dose-response relation between BMI and mortality in PH patients (Pnon−linearity < 0.001), with the lowest risk being at BMI 32–38 kg/m2. Conclusion Higher BMI is related to decreased risk of mortality among PH patients and the lowest point of the curve was seen at BMI 32–38.

Abstract
Non-invasive positive pressure ventilation (NPPV), an essential respiratory support method, is widely used in acute/chronic respiratory failure and assisting rehabilitation in patients with chronic obstructive pulmonary disease (COPD). We searched the relevant research articles about NPPV published from 1st October 2020 to 30th September 2021 through Medline. Researches focusing on the clinical application and viral transmission protection during high-flow nasal cannula oxygen and NPPV in COVID-19, were mainly retrospective and of small sample size. It demonstrated that high-flow nasal cannula oxygen and NPPV might reduce intubation rates when treating patients with mild-to-moderate respiratory failure, but the risk of delayed intubation should draw particular precaution. When using NPPV in non-COVID-19-related de novo acute respiratory failure, diaphragm thickening fraction and tidal change of esophageal pressure were validated to predict the treatment outcome. In addition, some studies explored the compliance and related influencing factors associated with the treatment effects of early NPPV initiation on amyotrophic lateral sclerosis patients and the effects of NPPV on dynamic hyperinflation during exercise in COPD patients. Furthermore, the effectiveness of neurally adjusted ventilatory assist ventilation and a novel communication device optimizing the use of NPPV were also investigated and outlined.

Abstract
The crucial role of the parietal cortex in working memory (WM) storage has been identified by fMRI studies. However, it remains unknown whether repeated parietal intermittent theta‐burst stimulation (iTBS) can improve WM. In this within‐subject randomized controlled study, under the guidance of fMRI‐identified parietal activation in the left hemisphere, 22 healthy adults received real and sham iTBS sessions (five consecutive days, 600 pulses per day for each session) with an interval of 9 months between the two sessions. Electroencephalography signals of each subject before and after both iTBS sessions were collected during a change detection task. Changes in contralateral delay activity (CDA) and K‐score were then calculated to reflect neural and behavioral WM improvement. Repeated‐measures ANOVA suggested that real iTBS increased CDA more than the sham one (p = .011 for iTBS effect). Further analysis showed that this effect was more significant in the left hemisphere than in the right hemisphere (p = .029 for the hemisphere‐by‐iTBS interaction effect). Pearson correlation analyses showed significant correlations for two conditions between CDA changes in the left hemisphere and K score changes (ps <.05). In terms of the behavioral results, significant K score changes after real iTBS were observed for two conditions, but a repeated‐measures ANOVA showed a nonsignificant main effect of iTBS (p = .826). These results indicate that the current iTBS protocol is a promising way to improve WM capability based on the neural indicator (CDA) but further optimization is needed to produce a behavioral effect.

Abstract
OBJECTIVE The aim of this study is to uncover the correlations of the expression of colon cancer associated transcript 2 (CCAT2) in the clinical papillary thyroid carcinoma (PTC) and anaplastic thyroid carcinoma (ATC) specimens with the prognosis and chemoresistance of patients. PATIENTS AND METHODS The expression level of CCAT2 in the PTC and ATC specimens was determined using Real-Time quantitative Polymerase Chain Reaction (RT-qPCR), and the correlations of CCAT2 expression with the clinical features of patients were detected via χ2 test. Besides, survival analysis was conducted to verify the relation between CCAT2 expression and patients' survival. After knockdown or overexpression of CCAT2, the changes in the proliferation ability of human thyroid carcinoma cells were examined via Cell Counting kit-8 (CCK-8) assay, and the half maximal inhibitory concentration (IC50) values of doxorubicin and cisplatin were measured by methyl thiazolyl tetrazolium (MTT) assay. RESULTS According to the χ2-test results, the expression of CCAT2 was notably correlated with the capsular invasion and lymph node metastasis of PTC, and the capsular invasion, tumor size, and lymph node metastasis of ATC. It was discovered through the survival analysis that the expression of CCAT2 was notably associated with the poor prognosis of ATC patients. After knockdown of CCAT2, both the proliferation ability and the IC50 values of doxorubicin and cisplatin substantially declined in human thyroid carcinoma cells. The opposite conditions were found after CCAT2 was overexpressed in human thyroid carcinoma cells. CONCLUSIONS CCAT2 potentiates the proliferation ability and chemoresistance of cells, promotes the progression of thyroid carcinoma, and hinders the prognosis of ATC.

Abstract
OBJECTIVE To develop a nano-delivery system for targeted delivery of miR-16/polypeptide for enhancing cisplatin sensitivity of ovarian cancer. OBJECTIVE R9-SS-R9 and cRGD-R9-SS-R9 peptides were synthesized and self-assembled with miR-16 molecules to form a nano-delivery system. The stability, particle size, potential and morphology of the nanoparticles were determined by agarose gel electrophoresis, particle size potentiometer and transmission electron microscopy. CCK-8 assay was used to assess the toxicity of the polypeptides in ovarian cancer cells. Stem loop qRT-PCR and living cell imaging were used to verify the uptake efficiency and intracellular distribution of the nanoparticles. Flow cytometry and Western blotting were performed to verify the effect of the nanoparticles for enhancing cisplatin sensitivity of ovarian cancer cells and explore the possible mechanism. OBJECTIVE R9-SS-R9/miR-16 and cRGD-R9-SS-R9/miR-16 nanoparticles were successfully prepared. The nanoparticles, with a particle size below 150 nm, a dispersity index less than 0.1 and a potential of about 40 mV, showed a good serum stability. The polypeptide material had no obvious cytotoxicity. The miR-16/polypeptide nanoparticles could be efficiently absorbed by human ovarian cancer cells and were distributed in the cytoplasm. The nanoparticles significantly increased the intracellular expression level of miR-16 (P < 0.001) and decreased the expression of Bcl-2 and Chk-1 proteins in ovarian cancer cells, thus enabling miR-16 to promote apoptosis and enhance cisplatin sensitivity of the cells. OBJECTIVE We successfully prepared a miR-16/polypeptide nano-delivery system for targeted delivery of miR-16 to ovarian cancer cells for enhancing cisplatin sensitivity of the cancer cells.

Abstract
BACKGROUND Myocardial infarction (MI) is cardiac tissue necrosis caused by acute and persistent ischemic hypoxia of the coronary arteries. This study is aimed at investigating the expression of long noncoding RNA (lncRNA) LINC00261 in MI and its effect on myocardial cells. METHODS qRT-PCR was performed to detect the expression levels of LINC00261, miR-522-3p, and TNRC6A in normal and MI cells. Western blotting analysis was performed to detect the expression of TNRC6A protein. Viability and apoptosis of myocardial cells after MI with the knockout of LINC00261 or TNRC6A were detected. The relationships among miR-522-3p, LINC00261, and TNRC6A in cardiomyocytes were evaluated using a double luciferase reporter gene assay. Hypoxic preconditioning in normal cells was used to construct a simulated MI environment to investigate the effect of LINC00261 on apoptosis of cardiac cells. RESULTS LINC00261 and TNRC6A were upregulated, while miR-522-3p was downregulated in coronary heart disease tissues with MI. Knockout of LINC00261 can increase the viability of cardiomyocytes and inhibit cell apoptosis. LINC00261 targets miR-522-3p in cardiomyocytes. In addition, miR-522-3p targets TNRC6A in cardiomyocytes. TNRC6A regulates cell viability and apoptosis of cardiomyocytes after MI, and TNRC6A-induced MI can be reversed by overexpression of miR-522-3p. CONCLUSIONS LINC00261 downregulated miR-522-3p in cardiomyocytes after MI by directly targeting miR-522-3p. TNRC6A is the direct target of miR-522-3p. Our results indicated that LINC00261 might serve as a therapeutic target for the treatment of MI.

Abstract
OBJECTIVE To investigate the effect of exosomes derived from bone marrow mesenchymal stem cells (BMMSC-Exos) on diabetic nephropathy (DN) rats and its possible mechanism. METHODS Thirty rats were divided into the following three groups of 10 rats each: the NC group (normal rats), the DN group (rats with DN), and the BM group (DN rats injected with BMMSC-Exo). Blood glucose level, renal function, blood lipid level, and plasma viscosity of the rats were detected. Renal tissue morphology was observed using hematoxylin-eosin staining. Expression levels of JAK2 and STAT3 in rats' kidneys were measured by RT-PCR and western blot. RESULTS The rats in the DN group had higher levels of blood glucose, blood lipids, and blood viscosity, worse renal function, and lower body weight than those in the NC group (all P<0.05). After treatment with BMMSC-Exos, rats in the BM group had markedly decreased levels of blood glucose, blood lipids, and blood viscosity, improved renal function, and higher body weight compared to those in the DN group (all P<0.05). The renal tissues in the NC group had intact structure, and no hyperplastic or hypertrophic cells were observed. In the DN group, the renal glomerulus and mesangial matrix were abnormal, and the capillary lumen and renal tubule lumen were depressed and blocked, accompanied by interstitial edema. Pathologic changes in the renal glomerulus and tubule in the BM group were less severe than those in the DN group. The DN rats had higher expression levels of JAK2 and STAT3 than normal rats, and the rats treated with BMMSC-Exos had lower levels of JAK2 and STAT3 compared to the DN rats (all P<0.05). CONCLUSION BMMSC-Exo can achieve a good therapeutic effect in DN, which may be due to its ability to lower the blood glucose level, improve renal function, and inhibit JAK2/STAT3 expression.

Abstract
INTRODUCTION Hypertension disorder of pregnancy (HDP) is one of the leading causes of maternal and foetal illness. The aim of the current study was to identify and verify novel serum markers for HDP. METHODS A label-free LC-MS/MS method was used to establish the serum proteomic profiles of 12 pre-HDP (before clinical diagnosis of HDP) pregnancies and verify prioritized candidates in the verification set of 48 pre-HDP pregnancies. These biomarkers were revalidated by ELISA in an independent cohort of 88 pre-HDP pregnancies. Subsequently, the candidate biomarkers were histologically analysed by immunohistochemistry, and function was evaluated in TEV-1 cells. RESULTS We identified 33 proteins with significantly increased abundance and 14 with decreased abundance (peptide FDR ≤ 1%, P < 0.05). Complement was one of the top enriched components in the pre-HDP group compared with the control group. Three complement factors (CLU, CFHR5, and CRP) were significantly increased in the three sets, of which CLU was a critical factor for the development of HDP (OR = 1.22, P < 0.001). When these three factors and body weight were combined, the AUC was 0.74, with a sensitivity of 0.67 and specificity of 0.68 for HDP prediction compared with normal pregnancy. In addition, inflammation-induced CLU could inhibit the invasion of TEV-1 cells. CONCLUSIONS Complement proteins may play an essential role in the occurrence of HDP by acting on trophoblast cells. CLU may be a high-risk factor for HDP, and the models combining candidates show reasonable screening efficiency of HDP in the first half of pregnancy.

Methods: Four hundred cases of congenital heart disease diagnosed by echocardiography during pregnancy were examined the fetal cardiovascular malformation and visceral malformation, and the absence of arterial duct was analyzed. Results: There were 24(6%)cases of absence of arterial duct, including 19 cases of left aortic arch and five cases of right aortic arch. There were 21 cases with main pulmonary arteries and 3 cases without main pulmonary arteries and branches. There were 15 cases of pulmonary artery stenosis with absence of arterial duct and the major cardiovascular malformations included six cases of single ventricle, six cases of atrial septal defect, four cases of single atrium, four cases of right atrium isomerism, four cases of double outlet right ventricle, four cases of anomalous pulmonary venous drainage, three cases of tetralogy of Fallot, and three cases of persistent left superior vena cava. There were seven cases of pulmonary atresia with absence of arterial duct and with systemic-pulmonary collateral circulation. There was one case of tetralogy of Fallot with absent pulmonary valve and absent arterial duct and the pulmonary artery was dilated. There was one case of aortopulmonary septal defect with absent arterial duct, with normal pulmonary artery. There were also seven cases of asplenia, seven cases of pulmonary abnormality and seven cases of visceral inversion. Conclusions: The absence of arterial duct is often associated with congenital heart disease. Pulmonary atresia is often associated with systemic-pulmonary collateral circulation. The visceral malformations are related to the accompanying congenital cardiovascular malformations.

Abstract
BACKGROUND Advances in lung cancer therapy have resulted in improved clinical outcomes. Unfortunately, advances can come at a financial cost to patients and their families that poses a significant risk to overall quality of life (QoL). Financial distress has been shown to be associated with increased symptom burden and decreased treatment compliance but the magnitude of financial distress is not well characterized in lung cancer populations. PATIENTS AND METHODS Patients with stage II-IV newly diagnosed lung cancer and starting first-line therapy were recruited at a tertiary academic institution between July 2018 and April 2019. The comprehensive score for financial toxicity (COST) was used to assess financial toxicity and the Functional Assessment of Cancer Therapy-Lung (FACT-L) was used to assess QoL. Associations between financial toxicity and baseline variables were assessed using multivariable linear regression and correlations were assessed using the Pearson correlation. RESULTS In this study, 143 consecutive patients were approached and 91.6% agreed to participate (N = 131). The median age was 65 years (35-90); 52.7% were male (n = 69), and 75.6% were white (n = 99). The inability to afford basic necessities and having <1 month of savings was associated with increased financial toxicity (P < 0.001) after adjusting for other factors such as age, race, insurance, and income. There was also a trend toward increased financial toxicity among those who were employed but on sick leave (P = 0.06). Increased financial toxicity was correlated with a decrease in QoL (correlation coefficient 0.41, P < 0.001). Patients' anticipated out-of-pocket (OOP) expenses for the upcoming 6 months ranged from $0 to $50 000 (median $2150). However, there was no correlation between anticipated OOP expenses and either financial toxicity or QoL. CONCLUSIONS These data identify key factors for identifying at-risk patients and builds a framework for exploring the benefit of financial counseling interventions, which may improve QoL and oncologic outcomes.

Abstract
FAIMS interface is gaining popularity because of the impressive 100-fold signal to noise enhancement in addition to the recent coupling to the Orbitrap technology, the most important analyzer developed in the last 20 years. The selection of group of ions and effective removal of single-charged ones at particular compensation voltages increases around 50% the proteome coverage at expenses of lower peptides coverage. However, specific setting for phosphoproteome analysis is yet poorly described. Here we have found the maximum transmission for several tryptic phosphopeptides isolated from a single complex mixture and we have set an experimental method based on five compensation voltages partially different to the ones described previously, demonstrating the relevance of voltages higher than 47 V, with an increase of around 20% of unique phosphopeptides. Using this experimental setup two complex phosphoproteomes isolates (SH-SY5Y cell line and plasma) were analyzed and found increments of 50% on phosphopeptides identification with the proposed method with respect to a previous one, for the cell line extract. Meanwhile for plasma 109 of the detected phosphopeptides are found for first time in this body fluid, presumably due to the release of intracellular proteins. With this FAIMS setup, 60% of the proteins identified are classified as very low abundant proteins.

Abstract
Implant dentistry has emerged as a first line of treatment to replace missing teeth for both the edentulous and partially dentate patients. Implant dentistry is accompanied by the onset of peri-implantitis (PIM). PIM is characterized by the inflammatory destruction of the implant-supporting tissues, because of biofilm formation on the implant surface. A history of periodontitis, poor oral hygiene, and smoking are considered as risk factors for PIM. Occasionally PIM is associated with iatrogenic factors, that, only recently, have been acknowledged as direct cause of PIM, i.e.: non-parallel adjacent implants or the presence of a gap, between fixture and prosthetic components. The use both of traditional protocols of nonsurgical periodontal therapy and the laser seems to be an effective alternative treatment modality for PMI. By the application of laser-assisted non-surgical peri-implant therapy the periodontal pocket depth was reduced. The present article illustrates the nonsurgical management of one case, where failure to remove residual cement, from an implant-supported dental prosthesis, seemed to cause PMI.

Abstract
LINGO-1(LRR and Ig domain-containing NOGO receptor interacting protein 1) is a viable target for spinal cord injury (SCI) repair due to its potent negative regulation in neuron survival and axonal regeneration. Although promising, the intracellular mechanism underlying LINGO-1 regulation is unclear. Here, we identified miR-615 as a potential microRNA (miRNA) that directly targets LINGO-1 by binding its 3'-untranslated region (3'-UTR) and caused the translation inhibition of LINGO-1. MiR-615 negatively regulated LINGO-1 during neural stem cell (NSC) differentiation and facilitated its neuronal differentiation in vitro. Interestingly, compared to the control, neurons differentiated from miR-615-treated NSCs were immature with short processes. Further results showed LINGO-1/epidermal growth factor receptor (EGFR) signaling may be involved in this process, as blockade of EGFR using specific antagonist resulted in mature neurons with long processes. Furthermore, intrathecal administration of miR-615 agomir in SCI rats effectively knocked down LINGO-1, increased neuronal survival, enhanced axonal extension and myelination, and improved recovery of hindlimbs motor functions. This work thus uncovers miR-615 as an effective miRNA that regulates LINGO-1 in NSC and SCI animals, and suggests miR-615 as a potential therapeutic target for traumatic central nervous system (CNS) injury.

Abstract
BACKGROUND Diesel engine exhaust (DEE) exposure causes lung cancer, but the molecular mechanisms by which this occurs are not well understood. OBJECTIVES To assess transcriptomic alterations in nasal epithelium of DEE-exposed factory workers to better understand the cellular and molecular effects of DEE. METHODS Nasal epithelial brushings were obtained from 41 diesel engine factory workers exposed to relatively high levels of DEE (17.2-105.4 μg/m3), and 38 unexposed workers from factories without DEE exposure. mRNA was profiled for gene expression using Affymetrix microarrays. Linear modeling was used to identify differentially expressed genes associated with DEE exposure and interaction effects with current smoking status. Pathway enrichment among differentially expressed genes was assessed using EnrichR. Gene Set Enrichment Analysis (GSEA) was used to compare gene expression patterns between datasets. RESULTS 225 genes had expression associated with DEE exposure after adjusting for smoking status (FDR q < 0.25) and were enriched for genes in pathways related to oxidative stress response, cell cycle pathways such as MAPK/ERK, protein modification, and transmembrane transport. Genes up-regulated in DEE-exposed individuals were enriched among the genes most up-regulated by cigarette smoking in a previously reported bronchial airway smoking dataset. We also found that the DEE signature was enriched among the genes most altered in two previous studies of the effects of acute DEE on PBMC gene expression. An exposure-response relationship was demonstrated between air levels of elemental carbon and the first principal component of the DEE signature. CONCLUSIONS A gene expression signature was identified for workers occupationally exposed to DEE that was altered in an exposure-dependent manner and had some overlap with the effects of smoking and the effects of acute DEE exposure. This is the first study of gene expression in nasal epithelial cells of workers heavily exposed to DEE and provides new insights into the molecular alterations that occur with DEE exposure.

Abstract
BACKGROUND Genetic factors have been suggested to affect the efficacy of working memory training. However, few studies have attempted to identify the relevant genes. METHODS In this study, we first performed a randomized controlled trial (RCT) to identify brain regions that were specifically affected by working memory training. Sixty undergraduate students were randomly assigned to either the adaptive training group (N = 30) or the active control group (N = 30). Both groups were trained for 20 sessions during 4 weeks and received fMRI scans before and after the training. Afterward, we combined the data from the 30 participants in the RCT study who received adaptive training with data from 71 additional participants who also received the same adaptive training but were not part of the RCT study (total N = 101) to test the contribution of the COMT Val158/108Met polymorphism to the interindividual difference in the training effect within the identified brain regions. RESULTS In the RCT study, we found that the adaptive training significantly decreased brain activation in the left prefrontal cortex (TFCE-FWE corrected p = .030). In the genetic study, we found that compared with the Val allele homozygotes, the Met allele carriers' brain activation decreased more after the training at the left prefrontal cortex (TFCE-FWE corrected p = .025). CONCLUSIONS This study provided evidence for the neural effect of a visual-spatial span training and suggested that genetic factors such as the COMT Val158/108Met polymorphism may have to be considered in future studies of such training.

Abstract
Objective: To explore the short-term outcomes of patients with coronary artery disease (CAD) who underwent coronary artery bypass graft (CABG) with sequential radial artery graft. Methods: Clinical data of patients with CAD who underwent CABG with sequential radial artery graft from August to December 2018 in Beijing Anzhen Hospital was retrospectively analyzed. Computer tomography angiography was employed to evaluate the patency of grafts and the incidence of adverse cardiovascular events was followed up 3 months after surgery. Results: A total of thirty patients were included, with an average age of (60.2±7.3) years old, among whom 83.3% were male, and 93.3% had three-vessel disease detected by coronary angiography. All patients had left internal mammary artery (LIMA) anastomosed to the left anterior descending (LAD) and sequential radial artery graft. Among sequential radial artery grafts, the most frequent anastomosis of sequential radial artery graft was aortic artery (AO)-first diagonal branch (D1)-first obtuse marginal branch (OM1) (13 patients, 43.3%), followed by AO-OM1-second obtuse marginal branch (OM2) (9 patients, 30.0%), and 18 patients also underwent saphenous vein graft. None of 30 patients experienced adverse cardiovascular events during postoperative period in hospital. Three-months follow-up outcomes showed that LIMA-LAD in 1 patient (3.3%) occluded, 3 patients had occluded anastomosis of sequential radial artery graft, 1 patient (3.3%) had heart failure, and 1 patient (3.3%) had recurrent angina. Conclusion: The radial artery could be used as the second arterial graft for CAD patients undergoing CABG with a sequential anastomosis technique, and these patients need regular anti-arterial spasm drug treatment after CABG.

Abstract
Hydroxyapatite/graphene oxide/platinum (HA/GO/Pt) nanocomposite was synthesized and electrodeposited on a pure zirconium substrate. The coated zirconium was annealed at 200, 300, 400, and 600°C in vacuum furnace in presence of argon gas. The structure and morphology of the coated samples were characterized. Biocompatibility and wear and corrosion resistances of specimens were examined. The result of corrosion tests shows that the graphene into HA/Pt composites significantly improves their corrosion resistance. The wear tests results of uncoated and coated samples before and after annealing show that coated samples annealed at 300°C had better wear resistance compared with uncoated and coated samples at other temperatures. Furthermore, the biocompatibility test shows that the coatings improved the cell attachment and proliferation compared to the pure zirconium substrate.

Abstract
Double-stranded RNA (dsRNA) length may affect RNA interference (RNAi) efficacy. Herein, variation in RNAi efficacy associated with dsRNA molecular length was confirmed via comparison of knockdown results following dsRNA injection into Tribolium castaneum. Through in vitro experiments with T. castaneum midgut, dsRNA accumulation in the midgut, degradation by midgut homogenates and persistence in haemolymph after injection were tested to determine the causes of RNAi efficacy variation. The comparative efficacies of dsRNAs were 480 bp ≈ 240 bp > 120 bp > 60 bp >> 21 bp. The combined midgut dsRNA accumulation and midgut homogenate-induced degradation analyses suggested cellular uptake to be the key barrier for 21 bp dsRNA functioning, but was likely not the main determinant of the variation in longer dsRNAs' (≥60 bp) bioactivity. In vitro RNAi experiment with T. castaneum midgut showed that long dsRNAs all significantly depleted the expression of corresponding genes, suggesting little variation in intracellular RNAi machinery's affinity for different dsRNA lengths. In vivo haemolymph content dynamics of different dsRNAs following injection indicated higher persistence of longer dsRNAs. In addition, comparison of the in vivo and in vitro RNAi efficacy also indicated the importance of haemolymph degradation. Thus, the varied efficacy of long dsRNAs resulted from their degradation by nucleases, which varied with dsRNA length.
