Abstract
Abstract
Purpose
Cardioprotective strategies against ischaemia-reperfusion injury (IRI) that remain effective in the clinical arena need to be developed. Here, we examined the efficacy of the cardioprotective compounds fingolimod (Fingo), empagliflozin (Empa), melatonin (Mela) and nicotinamide riboside (NR) in the presence of drugs routinely used clinically in IRI conditions such as cardiac by-pass surgery and PCI procedures (opiates, benzodiazepines, P2Y12 antagonist, propofol). Furthermore, we examine the mechanism of protection of effective compound(s).
Methods
Following pilot dose-response curves of each compound, cardioprotective efficacy of Fingo, Empa, Mela and NR in an in vivo rat model employing a clinically relevant anaesthetic background therapy (fentanyl-midazolam) were examined alone or in combination. Drugs were administered 30 min before 25 min left ascending coronary (LAD) ischaemia. Infarct size (IS) was determined following 2 h of reperfusion. Effective treatments were then tested in the presence of a P2Y12 antagonist (cangrelor) or propofol anaesthesia. Finally, the underlying metabolic mechanism of the efficient compound(s) was explored in an ex vivo Langendorff-perfused mouse heart model of cardiac IRI.
Results
We found that among these four compounds, only singular NR was able to reduce IS (30±14% vs 60±16%, P=0.009 vs control, Fig.1A) in vivo in the presence of clinically relevant background anaesthesia. NR still reduced IS in the presence of cangrelor (51±18% vs 71±4%, P=0.016 vs control, Fig.1B), but lost protection in the presence of propofol anaesthesia (62±16% vs 60±14%, P=0.839 vs control, Fig.1C). Furthermore, NR showed protection in the ex vivo model of IRI, where isolated hearts were perfused with glucose (G) and free fatty acid (FFA) palmitate (G+FFA): (IS%: 40±14% vs 64±12%, P=0.003 vs control; LDH release: 28.3±7.2 U/min/GWW vs 37.8±3.7 U/min/GWW, P=0.005 vs control; Rate-Pressure-Product (RPP) recovery (43±12% vs 31±8%, P=0.031 vs control, Fig.2A-C). However, NR's protection was lost when 1) glycolysis was by-passed, by replacing glucose in the perfusate with lactate (L) and pyruvate (P) (LP+FFA) or 2) glycolysis was overly activated by adding insulin to the perfusate (G+FFA+insulin) (Fig.2).
Conclusion
Our data suggests that NR is a promising cardioprotective agent to target cardiac ischaemia-reperfusion injury in clinical conditions employing opioid agonists, benzodiazepines and platelet P2Y12 inhibitors. This protection may, at least partly, be due to NR stimulation of cardiac glycolysis.

Abstract
Objective: To identify age and gender standardized body mass index among children and adolescents and explore their associations with high blood pressure (HBP) in late adolescence. Methods: The current study was based on the Health Promotion Program for Children and Adolescents, school-based surveillance successively conducted from 2012 to 2019 in Suzhou, China. A total of 11 812 children and adolescents aged 16-18 years, who had ≥4 examination records during 2012-2018 and were also involved in a surveillance program in 2019, were included. Latent class growth mixture modeling was used to identify the BMI-Z trajectories in different genders, and multivariate logistic regression was used to analyze the associations between different BMI-Z trajectories and risk of HBP in late adolescence. Results: Six distinct BMI-Z trajectories were determined for both genders:thin, slightly thin,standard, declining, overweight, and obese. Compared with the regular group, the obesity group had 94.0% (OR=1.94, 95%CI: 1.43-2.63) and 107.0% (OR=2.07, 95%CI: 1.33-3.22) increased risk of developing HBP in late adolescence in boys and girls, respectively. However, a neutral association was found between the descending group and HBP in late adolescence. Conclusions: Persistent obesity in children may increase the risk of HBP in their late adolescence. If an obese child restores normal weight before late adolescence, the risk of HBP may reduce.

MiR-466 as a poor prognostic predictor suppresses cell proliferation and EMT in breast cancer cells by targeting PSMA7. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2021; 25:5625-5635.

Abstract
OBJECTIVE MiR-466 has been reported to exert a tumor-suppressive role in several cancers, including colorectal cancer and osteosarcoma, but its clinical significance and functional mechanisms in breast cancer (BC) pathogenesis still remain elusive. PATIENTS AND METHODS The expression of miR-466 was determined using reverse transcription quantitative PCR. The clinical significance of miR-466 in BC patients was assessed by Chi-square test, Kaplan-Meier method and Cox regression analyses. Functional experiments, including CCK-8 and transwell assays, were performed to analyze cell proliferation, migration and invasion ability. The association between miR-466 and proteasome subunit α7 (PSMA7) was confirmed by Luciferase reporter assay. RESULTS Here, we first observed that the expression of miR-466 was significantly downregulated in BC tissues and cell lines. The decreased miR-466 expression was significantly associated with tumor size (p = 0.003), lymph node metastasis (p = 0.008), TNM stage (p = 0.032) and poor survival rate. In addition, miR-466 was identified as an independent prognostic factor for BC patients. We further found that the overexpression of miR-466 significantly inhibited cell proliferation, migration and invasion. Mechanistically, PSMA7 was a potential target gene of miR-466 and negatively regulated miR-466 in BC cells. Oncomine database and Kaplan-Meier overall survival analysis indicated that upregulation of PSMA7 was associated with poor prognosis of BC patients. The rescue experiments demonstrated that PSMA7 overexpression reversed the effects of miR-466 on cell proliferation, migration, invasion and EMT transcription factors (E-cadherin, N-cadherin, and vimentin). CONCLUSIONS Collectively, these results suggest that the miR-466/PSMA7 axis might have potential as a therapeutic target for BC treatment.

Increased risk of diabetes in cancer survivors: a pooled analysis of 13 population-based cohort studies. ESMO Open 2021; 6:100218.

Abstract
BACKGROUND Diabetes is considered as an established risk factor for cancer development. However, the link between diabetes among cancer survivors remains inconclusive. The hypothesis of this study was to assess the hazard ratio (HR) of incidence of diabetes in cancer survivors compared with the HR in the general population. PATIENTS AND METHODS A comprehensive literature search was performed in PubMed, Embase, and the Cochrane Library from database inception to 15 December 2020 for population-based cohort studies. Summary effect estimates were combined using random-effects models. We also performed subgroup analyses to test sources of heterogeneity and the stability of the results stratified by various study and participant characteristics. RESULTS Thirteen population-based cohort studies involving 1 686 595 participants were analyzed. The HR for the development of diabetes in cancer survivors was 1.39 [95% confidence interval (CI) 1.29-1.50; I2 = 82.3%; P < 0.001] compared with that in noncancer controls, among which survivors of hematological, gynecologic, breast, colorectal and urinary tract cancer (all P < 0.05) showed consistent significant results, whereas no significant increased risk was observed for other cancer types. The effects were more prominent in populations of shorter cancer survival duration (<1 year) (HR 2.09, 95% CI 1.32-3.32; P = 0.009). Moreover, cancer survivors with a longer follow-up period (>10 years) had a relatively higher risk of diabetes (HR 1.54, 95% CI 1.34-1.77) than those with a shorter follow-up period. CONCLUSIONS In this large pooled analysis of population-based cohorts, evidence supports the hypothesis that the risk of developing diabetes is increased in cancer survivors compared with the general population. We should interpret the results with caution for considerable interstudy heterogeneity. However, health policy makers should take this as a challenge for the early prevention and effective intervention of diabetes.

Abstract
OBJECTIVE To establish an indicator system for assessment of schistosomiasis transmission risk after transmission interruption in Hubei Province, so as to provide insights into the precise control of schistosomiasis. METHODS The indicator system was preliminarily established based on data collection, literature review, expert interviews. Two rounds of expert consultation were performed. The indicator system was screened based on the importance, operability, sensitivity and comprehensive score of the indicators, and the weights of each indicator were calculated. The credibility of the Delphi method was evaluated by calculating the active coefficient of the experts, degree of expert authority and coordination levels of experts' opinions. RESULTS An indicator system for assessment of schistosomiasis transmission risk was preliminarily established, including 3 primary indicators, 12 secondary indicators and 44 tertiary indicators. A Delphi consultation was performed among 17 experts participating in schistosomiasis control, management and research. Following two rounds of consultation, a risk assessment indicator system was finally constructed, including 3 primary indicators, 10 secondary indicators and 35 tertiary indicators. Among the primary indicators, the variable with the highest normalized weight was the current status of schistosomiasis (0.420 2), followed by social factors (0.397 3) and natural environments (0.182 5). Among the secondary indicators, those with high combined weights included risk monitoring (0.142 3), current snail status (0.140 1), and current prevalence of human and livestock infections (0.137 8). Among the tertiary indicators, those with high combined weights included the positive rate of wild feces (0.049 8), the prevalence of snail infections (0.047 4), and the area of snail habitats submerged by floods (0.046 8). During the two-round consultation, the active coefficients of the experts were 85.00% and 100.00%, the degree of expert authority was both 0.75 and greater, and the coordination levels of experts' opinions were 0.405 to 0.521 and 0.592 to 0.695 (all P values < 0.05). CONCLUSIONS An indicator system for assessment of schistosomiasis transmission risk is successfully established after transmission interruption in Hubei Province based on the Delphi method, which provides insights into the identification of the schistosomiasis transmission risk and the targets for schistosomiasis control in Hubei Province.

Abstract
BACKGROUND Previous studies have suggested that item memory is processed based on both familiarity and recollection, and evidence can be found from behavioral as well as event-related potential (ERP) patterns. Recently, great consideration has been given to how the memory of items generated from internal and external sources differ from each other. To date, the modulation of fluency, perceptual fluency in particular, on item memory has been rarely explored from both behavioral and neural perspectives. To address these issues, an ERP experiment was conducted. METHODS Stimuli were encoded in the status of perceived vs. imagined, of either high or low frequency, manipulated by times of exposure (once or twice). Subsequent memory for the items was tested, during which ERP signals were recorded. RESULTS AND CONCLUSION The findings of the old/new effects reveal the distinctiveness between perceived and imagined items, and demonstrate an influence of fluency, with higher accuracy for items of high fluency than those low fluent ones. The sensitivity of item memory to fluency was discussed in terms of the dual-process model, together with other possible accounts.

Abstract
The incidence of anastomotic leak after right hemicolectomy for cancer is relatively low, but it may be misjudged. In recent years, the results of some multi-center or nationwide registration studies in Europe have shown that the incidence of anastomotic leak is significantly higher than that of eastern countries. The reasons of these differences may be the different nature of the studies, the lack of rigor in diagnostic criteria or diagnostic methods, the difference in the level of specialization of hospitals or surgeons, and so on. Timely treatment of preoperative comorbidities, reasonable selection of preoperative bowel preparation and anastomotic technique/method might reduce the occurrence of anastomotic leak. The current evidence shows complete mesocolic excision (CME) does not increase the risk of anastomotic leak. The clinical features of ileo-colic anastomotic leak are different from those of rectal surgery. The mild cases can be treated conservatively, and the severe cases are suggested to receive timely diverting ileostomy.

Abstract
Objective: To investigate whether protective colostomy and protective ileostomy have different impact on anastomotic leak for rectal cancer patients after neoadjuvant chemoradiotherapy (nCRT) and radical surgery. Methods: A retrospectively cohort study was conducted. Inclusion criteria: (1) Standard neoadjuvant therapy before operation; (2) Laparoscopic rectal cancer radical resection was performed; (3) During the operation, the protective enterostomy was performed including transverse colostomy and ileostomy; (4) The patients were followed up regularly; (5) Clinical data was complete. Exclusion criteria: (1) Colostomy and radical resection of rectal cancer were not performed at the same time; (2) Intestinal anastomosis is not included in the operation, such as abdominoperineal resection; (3) Rectal cancer had distant metastasis or multiple primary colorectal cancer. Finally 208 patients were included in this study. They suffered from rectal cancer and underwent protective stoma in radical surgery after nCRT at our hospital from January 2014 to December 2018. There were 148 males and 60 females with age of (60.5±11.1) years. They were divided into protective transverse colostomy group (n=148) and protective ileostomy group (n=60). The main follow up information included whether the patient has anastomotic leak and the type of leak according to ISREC Grading standard. Besides, stoma opening time, stoma flow, postoperative hospital stay, stoma related complications and postoperative intestinal flora were also collected. Results: A total of 28 cases(13.5%) suffered from anastomotic leak and 26 (92.9%) of them happened in the early stage after surgery (less than 30 days) . As for these early-stage leak, ISREC Grade A happened in 11 cases(42.3%), grade B in 15 cases(57.7%) and no grade C occurred. There was no significant difference in the incidence [12.8% (19/148) vs. 15.0% (9/60) , χ(2)=0.171, P=0.679] or type [Grade A: 5.4%(8/147) vs. 5.1%(3/59); Grade B: 6.8%(10/147) vs. 8.5%(5/59), Z=0.019, P=1.000] of anastomotic leak between the transverse colostomy group and ileostomy group (P>0.05), as well as operation time, postoperative hospital stay, drainage tube removal time or stoma reduction time (P>0.05). There were 10 cases (6.8%) and 24 cases (40.0%) suffering from intestinal flora imbalance in protective transverse colostomy and protective ileostomy group, respectively (χ(2)=34.503, P<0.001). Five cases (8.3%) suffered from renal function injury in the protective ileostomy group, while protective colostomy had no such concern (P=0.002). The incidence of peristomal dermatitis in the protective colostomy group was significantly lower than that in the protective ileostomy group [12.8% (9/148) vs. 33.3%(20/60), χ(2)=11.722, P=0.001]. Conclusions: It is equally feasible and effective for rectal cancer patients after nCRT to carry out protective transverse colostomy or ileostomy in radical surgery. However, we should pay more attention to protective ileostomy patients, as they are at high risk of intestinal flora imbalance, renal function injury and peristomal dermatitis.

Abstract
Objective: Transanal total mesorectal excision (taTME) was a very hot topic in the first few years since its appearance, but now more introspections and controversies on this procedure have emerged. One of the reasons why the Norwegian Ministry of Health stopped taTME was the high incidence of postoperative anastomotic leak. In current study, the incidence and risk factors of anastomotic leak after taTME were analyzed based on the data registered in the Chinese taTME Registry Collaborative (CTRC). Methods: A case-control study was carried out. Between November 15, 2017 and December 31, 2020, clinical data of 1668 patients undergoing taTME procedure registered in the CTRC database from 43 domestic centers were collected retrospectively. After excluding 98 cases without anastomosis and 109 cases without complete postoperative complication data, 1461 patients were finally enrolled for analysis. There were 1036 males (70.9%) and 425 females (29.1%) with mean age of (58.2±15.6) years and mean body mass index of (23.6±3.8) kg/m(2). Anastomotic leak was diagnosed and classified according to the International Study Group of Rectal Cancer (ISREC) criteria. The risk factors associated with postoperative anastomotic leak cases were analyzed. The impact of the cumulative number of taTME surgeries in a single center on the incidence of anastomotic leak was evaluated. As for those centers with the number of taTME surgery ≥ 40 cases, incidence of anastomic leak between 20 cases of taTME surgery in the early and later phases was compared. Results: Of 1461 patients undergoing taTME, 103(7.0%) developed anastomotic leak, including 71 (68.9%) males and 32 (31.1%) females with mean age of (59.0±13.9) years and mean body mass index of (24.5±5.7) kg/m(2). The mean distance between anastomosis site and anal verge was (2.6±1.4) cm. Thirty-nine cases (37.9%) were classified as ISREC grade A, 30 cases (29.1%) as grade B and 34 cases (33.0%) as grade C. Anastomotic leak occurred in 89 cases (7.0%,89/1263) in the laparoscopic taTME group and 14 cases (7.1%, 14/198) in the pure taTME group. Multivariate analysis showed that hand-sewn anastomosis (P=0.004) and the absence of defunctioning stoma (P=0.013) were independently associated with anastomotic leak after taTME. In the 16 centers (37.2%) which performed ≥ 30 taTME surgeries with cumulative number of 1317 taTME surgeries, 86 cases developed anastomotic leak (6.5%, 86/1317). And in the 27 centers which performed less than 30 taTME surgeries with cumulative number of 144 taTME surgeries, 17 cases developed anastomotic leak (11.8%, 17/144). There was significant difference between two kinds of center (χ(2)=5.513, P=0.019). Thirteen centers performed ≥ 40 taTME surgeries. In the early phase (the first 20 cases in each center), 29 cases (11.2%, 29/260) developed anastomotic leak, and in the later phase, 12 cases (4.6%, 12/260) developed anastomotic leak. The difference between the early phase and the later phase was statistically significant (χ(2)=7.652, P=0.006). Conclusion: The incidence of anastomotic leak after taTME may be reduced by using stapler and defunctioning stoma, or by accumulating experience.

Performance of different methods for testing polymyxin B: comparison of broth microdilution, agar dilution and MIC test strip in mcr-1 positive and negative Escherichia coli. Lett Appl Microbiol 2021; 73:197-205.

Abstract
Antimicrobial susceptibility testing with the last-resort antibiotics polymyxins (polymyxin B and colistin) is associated with several methodological issues. Currently, broth microdilution (BMD) is recommended for colistin and polymyxin B. BMD is laborious and the utility of alternative methods needs to be evaluated for polymyxin B susceptibility testing. In this study, using BMD as a reference method, the performance of agar dilution (AD) and MIC test strips (MTS) were evaluated in polymyxin B susceptibility testing. BMD, AD and MTS were used to determine MICs of 193 clinical isolates of Escherichia coli. Seventy-nine were positive for the polymyxin resistance gene mcr-1. Method performances were evaluated based on pair-wise agreements with the reference method (BMD) and statistical testing. AD and MTS showed an unacceptable number of very major errors (VMEs) compared with BMD, 9·3 and 10·7%, respectively. The essential agreement (EA) was low for AD (49·7%), but high for MTS (97·8%). However, statistical testing showed that MTS tended to yield a one-step lower MIC (P < 0·01) compared with BMD. The discordances observed with MTS and AD in comparison with BMD for polymyxin B susceptibility testing for E. coli suggest their inapplicability in routine testing. A large number of isolates clustered around the susceptibility breakpoint (2-4 mg l-1 ) and several mcr-1 positive isolates (17%) were determined as susceptible with BMD. A screening breakpoint for mcr-1 of 2 mg l-1 should also be considered.

[PMID: 34171616 PMCID: PMC8157318 DOI: 10.1016/j.puhe.2021.05.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 04/19/2021] [Accepted: 05/12/2021] [Indexed: 11/07/2022]
Abstract
Objectives Although general principles related to vaccination hesitancy have been well researched, reports on reluctance to be vaccinated for coronavirus disease 2019 (COVID-19) in the United States are somewhat surprising, given the disease's substantive disruption of everyday life. However, the landscape in which people are making COVID-19 vaccination decisions has recently evolved with releases of encouraging vaccine-related data and changes to official messaging about the virus. Therefore, this study sought to identify factors associated with reported likelihood to get vaccinated for COVID-19 among US adults in late January 2021. Study design We used the Prolific online research panel to survey a nationally representative sample of 1017 US adults. Methods Respondents were asked about their behavioral intentions toward COVID-19 vaccination, trust in science, perceptions related to COVID-19, and selected sociodemographic factors. We computed associations between those 11 independent variables and likelihood to get vaccinated for COVID-19 using multiple linear regression. Results Around 73.9% of respondents indicated at least some likelihood to get vaccinated for COVID-19. Trust in science and perceived seriousness of COVID-19 were positively associated with intention to get vaccinated, and identifying as Black or African American was negatively associated with intention to get vaccinated. Other factors were moderately, weakly, or not at all associated with intention. Conclusions Building trust in science and truthfully emphasizing the seriousness of catching COVID-19 should be further researched for their potential to support campaigns to encourage COVID-19 vaccination. Data continue to suggest the importance of dialogue with Black communities about COVID-19 vaccination.

Abstract
Objective: To investigate the prognosis and postoperative complications of local excision for rectal cancer after neoadjuvant chemoradiotherapy (nCRT). Methods: A descriptive case series study was carried out. Patient inclusion criteria: (1) patients who underwent local excision by transanal endoscopic microsurgery (TEM) after nCRT; (2) magnetic resonance evaluated tumor regression grade (mrTRG) as 1, 2 after nCRT;(3) American Society of Anesthesiologists class I to III. Patient exclusion criteria: (1) with multiple primary colorectal cancers; (2) with other malignant tumors within five years; (3) with emergency surgicery indications like digestive tract obstruction, perforation or bleeding. Clinicopathological and follow-up data of rectal cancer patients with obvious tumor regression after nCRT who underwent local excision in Peking Union Medical College Hospital from January 2010 to August 2019 were retrospectively collected. Outcome measures included disease-free survival (DFS), short-term postoperative complications, and at postoperative 1-year during follow up, gas continence, fecal continence, and quality of life (using the EORTC QLQ-CR29 scale, higher score indicated worse quality of life) at postoperative 1-year. Results: A total of 40 patients were included in this study. There were 27 males and 13 females with an average age of (66.7±12.3) years. Preoperative rectal ultrasound and other imaging examinations indicated that the tumor was located in the anterior wall in 16 cases, the lateral wall in 12 cases, and the posterior wall in 12 cases. The distance between the lower margin of the tumor and the anal verge was (4.3±1.2) cm before nCRT and (5.1±0.9) cm after nCRT. According to mrTRG, 31 cases were assessed as mrTRG 1 and 9 cases as mrTRG 2. All the patients received local extended excision of rectal cancer using TEM platform. A total of 19 cases(47.5%) suffered from complications within one month postoperatively. Clavien-Dindo grade I complications happened in 14 cases, grade II in 3 patients, and grade III in 2 cases, who all were healed by conservative treatment. Except that 2 patient presented severe low anterior resection syndrome (LARS) at 1 year postoperatively, no severe anal dysfunction was found in this cohort patients. EORTC QLQ CR29 scale results for quality of life showed that at 1 year after TEM excision, except taste (Z=-1.968, P=0.049), anxiety (Z=-3.624, P<0.001) and skin irritation (Z=-2.420, P=0.023) were worse than the situation before neoadjuvant therapy, there were no statistically significant differences in other assessment results between pre-operation and post-operation (all P>0.05). Postoperative pathological results indicated complete tumor regression (pTRG0) in 17 cases, moderate remission (pTRG1) in 13, and mild remission (pTRG2) in 10. During the follow-up of (49.1±29.6) months, 3 patients had local recurrence and 4 had distant metastasis (3 patients with liver metastasis and 1 patient with lung metastasis followed by liver metastasis). No death was found and the 5-year disease-free survival (DFS) was 84.3%. Conclusions: Local excision through TEM following nCRT not only can be adopted as an important means to accurately determine complete clinical remission (cCR), but also has high therapeutic value for rectal cancer patients presenting cCR or near cCR, with little impact on defecatory function and quality of life. However, the morbidity of complication of TEM excision after nCRT is relatively high and there is a risk of recurrence and metastasis. Therefore, it is still necessary to strictly select the indications of local excision.

Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment: DUNE Collaboration. THE EUROPEAN PHYSICAL JOURNAL. C, PARTICLES AND FIELDS 2021; 81:322. [PMID: 34720713 PMCID: PMC8550327 DOI: 10.1140/epjc/s10052-021-09007-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Accepted: 02/23/2021] [Indexed: 06/13/2023]
Abstract
The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM). Of the many potential beyond the Standard Model (BSM) topics DUNE will probe, this paper presents a selection of studies quantifying DUNE's sensitivities to sterile neutrino mixing, heavy neutral leptons, non-standard interactions, CPT symmetry violation, Lorentz invariance violation, neutrino trident production, dark matter from both beam induced and cosmogenic sources, baryon number violation, and other new physics topics that complement those at high-energy colliders and significantly extend the present reach.

Abstract
OBJECTIVE To analyze the species, abundance and structure differences of intestinal flora between patients with type 2 diabetes mellitus (T2D) and healthy individuals and explore the correlation between intestinal flora changes and T2D. OBJECTIVE We collected a total of 133 clinical fecal samples from 78 healthy individuals and 55 patients with T2D. Hiseq2500 was used for high-throughput sequencing of the V3+V4 regions of the 16S rRNA gene. Usearch and QIIME were used for data splicing and filtering, classification and species annotation. The Alpha diversity index and Beta diversity index of the samples were analyzed using R language data packets to compare the richness and diversity of the sample flora. The flora differences were compared between the two groups and the disease marker flora was screened after correction of the relevant factors. PICRUST software was used to predict the function of different flora. OBJECTIVE There was significant difference in the intestinal flora diversity between the two groups. Cluster analysis showed that Fimicutes and Bacteroidetes were the dominant species at the phylum level. LefSe analysis showed that significant differences in the relative abundance between the two groups in 2 phyla, 3 classes, 3 orders, 4 families and 10 genera. After correction for the influence of related factors, the markers of T2Drelated bacteria groups were identified, including Bifidobacterium, Bifidobacteriales, Bifidobacteriaceae, Actinobacteria, Bacilli, Lactobacillales, Lactobacillaceae and Lactobacillus. On this basis, analysis of KEGG metabolic pathways of the differential flora revealed significant differences in 36 KEGG metabolic pathways between the two groups, and the citric acid cycle, lipopolysaccharide biosynthesis and other metabolic pathways were all up-regulated in T2D group. OBJECTIVE The composition and abundance of intestinal flora were different between T2D group and the normal group, and T2D group showed the characteristics of ecological imbalance.

Abstract
OBJECTIVE The purpose of this study was to investigate the effect of Casitas b-lineage lymphoma b (Cblb) on the regulation of T follicular helper (Tfh) in the development of lupus nephritis. MATERIALS AND METHODS The Tfh (CD4+CXCR5+PD-1+) cells in peripheral blood were analyzed by flow cytometry. Forty mice were divided into 4 groups (10/group), WT, lpr, Cblb-/- and lpr.Cblb-/-. Urine protein, serum creatinine, blood urea nitrogen (BUN), dsDNA, and antinuclear antibody (ANA) titer of mice were monitored once every four weeks. Peripheral blood mononuclear cells (PBMCs) from mice were collected to assess circulating Tfh. The expressions of Cblb in Tfh cells were regulated by transfecting siRNA and overexpression plasmid approach in vitro. RESULTS The patients with lupus nephritis (LN) had abnormal renal clinical manifestations compared with healthy volunteers. The peripheral Tfh cells were increased and the expression of Cblb were downregulated in patients with LN (p<0.05). Both lpr mice and lpr.Cblb-/- mice had LN symptoms. LN symptoms were more serious in lpr.Cblb-/- mice compared with that in lpr mice (p<0.05). The number of Tfh cells in peripheral blood from lpr.Cblb-/- mice was significantly higher than that from lpr mice (p<0.05). Overexpression of Cblb in Tfh cells led to reduction of IgG expression, while the knockdown of Cblb in Tfh cells was accompanied by increased expression of immunoglobulin (IgG) (p<0.05). CONCLUSIONS Cblb showed a negative regulatory effect on Tfh. The deletion of Cblb may be a key factor in progression of renal injury.

Abstract
OBJECTIVE To uncover the prognostic potentials of long non-coding RNA (lncRNA) UCA1 and miR-18a in hepatocellular cancer (HCC). PATIENTS AND METHODS Expression levels of UCA1 and microRNA-18a (miR-18a) in HCC tissues and adjacent normal ones harvested from 55 HCC patients were determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Clinical data of HCC patients were recorded, including pathological grading, tumor staging, intrahepatic metastasis, serum level of α-fetoprotein (AFP), tumor size, tumor number, recurrence, etc. Based on the median levels of UCA1 and miR-18a, enrolled HCC patients were classified into high-level and low-level group. Potential correlation between expression levels of UCA1 and miR-18a with survival of HCC patients was analyzed. The 5-year follow-up data of HCC patients were collected for analyzing factors that may influence prognosis in HCC patients by the Cox regression model. RESULTS UCA1 was upregulated and miR-18a was downregulated in HCC tissues. HCC patients with stage III-IV, tumor size ≥5 cm or multiple tumors expressed high level of UCA1. Besides, HCC patients with stage I-II, non-intrahepatic metastasis or primarily diagnosed expressed a relatively low level of miR-18a. High-level UCA1 and low-level miR-18a predicted worse prognosis in HCC patients. Cox regression analysis revealed that tumor node metastasis (TNM) staging, intrahepatic metastases, postoperative recurrences, and UCA1 were risk factors for HCC, while miR-18a was the protective factor. CONCLUSIONS LncRNA UCA1 is upregulated and miR-18a is downregulated in HCC tissues. High-level UCA1 and low-level miR-18a are closely linked to poor prognosis in HCC.

Abstract
BACKGROUND Accurate and robust pathological image analysis for colorectal cancer (CRC) diagnosis is time-consuming and knowledge-intensive, but is essential for CRC patients' treatment. The current heavy workload of pathologists in clinics/hospitals may easily lead to unconscious misdiagnosis of CRC based on daily image analyses. METHODS Based on a state-of-the-art transfer-learned deep convolutional neural network in artificial intelligence (AI), we proposed a novel patch aggregation strategy for clinic CRC diagnosis using weakly labeled pathological whole-slide image (WSI) patches. This approach was trained and validated using an unprecedented and enormously large number of 170,099 patches, > 14,680 WSIs, from > 9631 subjects that covered diverse and representative clinical cases from multi-independent-sources across China, the USA, and Germany. RESULTS Our innovative AI tool consistently and nearly perfectly agreed with (average Kappa statistic 0.896) and even often better than most of the experienced expert pathologists when tested in diagnosing CRC WSIs from multicenters. The average area under the receiver operating characteristics curve (AUC) of AI was greater than that of the pathologists (0.988 vs 0.970) and achieved the best performance among the application of other AI methods to CRC diagnosis. Our AI-generated heatmap highlights the image regions of cancer tissue/cells. CONCLUSIONS This first-ever generalizable AI system can handle large amounts of WSIs consistently and robustly without potential bias due to fatigue commonly experienced by clinical pathologists. It will drastically alleviate the heavy clinical burden of daily pathology diagnosis and improve the treatment for CRC patients. This tool is generalizable to other cancer diagnosis based on image recognition.

Abstract
Objective: To investigate the inhibitory effect and molecular mechanism of microRNA-30d (miR-30d) in the process of proliferation, migration and invasion of malignant mesothelioma cell line MSTO-211H. Methods: In April 2017, the human MSTO-211H cells was used to establish miR-30d overexpressed MSTO-211H cell model by transfection of miR-30d mimics. The qRT-PCR was performed to detect the expression level of miR-30d in the cells transfected miR-30d mimics. The effects of miR-30d on the proliferation, apoptosis, migration and invasion of MSTO-211H cells were analyzed by CCK-8 experiment, flow cytometry, cell scratch experiment and Transwell method. Results: After transfection of miR-30d, the expression level of miR-30d in the MSTO-211H+miR-30d cells group was significantly higher than MSTO-211H+miR NC cells group (P<0.01) . The cell activity of MSTO-211H+miR-30d group (105.13%±2.35%) was significantly lower than MSTO-211H+miR NC cells group (115.40%±1.35%) , and the level of apoptosis (3.97%±0.36%) was significantly higher than MSTO-211H+miR NC cells group (1.47%±0.10%) (P<0.01) . The relative migration areas at 12 and 24 h of MSTO-211H+miR-30d cells group (9.35±3.16 μm(2) and 58.19±1.82 μm(2)) were significantly lower than MSTO-211H+miR NC cells group (54.42±5.26 μm(2) and 88.32±1.96 μm(2)) (P<0.01) . Compared with the MSTO-211H+miR NC cells group, the numbers of cell migration and cell invasion were reduced in the MSTO-211H+miR-30d cells group (P<0.01) . Conclusion: miR-30d can regulate the progression of malignant pleural mesothelioma by inhibiting the proliferation, apoptosis, migration and invasion of MSTO-211H cells.

Abstract
Background
Data suggests that tight objective monitoring of inflammatory bowel diseases (IBD) may improve one-year clinical outcomes.
Aims
The goal of this study is to assess the adherence to serial tight objective monitoring, via clinical symptoms and biomarkers, and the effect of such tight monitoring on one year outcome in IBD patients at an academic and an university-affiliated center.
Methods
We retrospectively reviewed the chart of 428 consecutive IBD patients who started adalimumaby at the McGill University Health Center and Jewish General Hospital (Montreal, Canada) between January 1, 2015 and January 1, 2019 [338 Crohn’s disease(CD), 90 ulcerative colitis(UC)]. Clinical symptoms (assessed by Harvey-Bradshaw-Index and partial Mayo), C-Reactive Protein(CRP), and fecal calprotectin(FCAL) were captured at treatment initiation and at 3, 6, 9, and 12 months. Combined adherence was defined as the evaluation of ≥2 of 3 parameters(clinical, CRP, FCAL). Dose optimization and drug sustainability curves were plotted by Kaplan-Meier method.
Results
Clinical symptoms were assessed in nearly all patients at 3 (CD-UC:95-94%), 6 (90-83%), 9 (86-85%) and 12 (96-89%) months. CRP was also available for most patients but the frequency of assessment decreased in CD patients over the study period. In comparison, compliance to serial FCAL testing was low throughout the follow-up period. Clinical remission at one-year was significantly higher in patients who were adherent to early assessment visit at 3 months (p=0.001 both for CD and UC). Adherence to early follow-up also resulted in earlier dose optimisation in both CD and UC patients(pLogrank=0.026 for UC and p=0.09 for CD). However, the overall drug sustainability did not differ.
Conclusions
Clinical assessment and CRP, but not FCAL, were frequently assessed in patients starting adalimumab. Adherence to early objective combined follow-up visits resulted in earlier dose optimization and improved one-year clinical outcomes but did not change drug sustainability rates.

Abstract
MicroRNAs plays important role in cerebral ischemia-reperfusion (CIR). However, the role of miR-26b-5p in CIR injury remains unclear. PC12 cells were treated with oxygen-glucose deprivation (OGD) for 0 h, 2 h, 4 h, 6 h, and then reoxygenated for 24 h to construct an in vitro I/R model. Then, miR-26b-5p mimic, small interfering RNA of KLF10 and KLF10 overexpression plasmid were transfected into cells respectively for mechanism study. Our results showed that miR-26b-5p was downregulated in OGD/R-induced PC12 cells. After overexpression of miR-26b-5p, cell proliferation ability was enhanced, apoptosis, ROS and inflammatory mediators were inhibited. Bioinformatics analysis indicated that miR-26b-5p was directly bound to the 3' UTR of KLF10, and downregulated the expression of KLF10. KLF10 was upregulated in OGD/R cells, and transfection with si-KLF10 promoted cell proliferation and reduced apoptosis, NO concentration and inflammatory factor secretion. Moreover, pcDNA-KLF10 reversed the inhibitory effects of miR-26b-5p mimic on apoptosis, NO content and inflammatory factor secretion, as well as the downregulation of N-myc and PTEN expression. Meanwhile, I/R rat models were constructed and divided into sham operation group (femoral artery isolation only), model group (middle cerebral artery occlusion model of rats was prepared by thread embolization), treatment group (200 µL of miR-26b-5p mimic was injected into the brain of model rats). We observed that the infarct size of brain tissue was reduced, KLF10 expression was downregulated, and apoptosis and inflammatory response were reduced. These results suggest that miR-26b-5p had protective effects on CIRI and it may be a potential treatment target.

Abstract
Medication safety during care transitions is a significant challenge, especially for older adults prescribed multiple medications. Using a systems approach to understand barriers to and strategies for safe medication management throughout high-risk periods of hospital-to-home transition is one important step in designing effective interventions. Framing the care transition as a collaboration between healthcare and patient "work systems," we conducted semi-structured interviews with 37 clinical team members, representing 10 different professional roles involved in providing transitional care for patients. Thematic analyses identified key strategies used by clinical team members in preparing patients to self-manage medications safely in the home environment: (1) streamlining and coordinating clinical management of medication reconciliation across care settings; (2) building patient capacity and engagement in self-management of medications; and (3) redesigning the transitional process. Our research highlights the value in aligning professionals' care transition goals with patients and caregiver(s) to better prepare them to self-manage medications upon discharge.

Array-based comparative genomic hybridization (array-CGH) analysis and single nucleotide polymorphism array (SNP-array) were performed in 1 320 children with DD/ID, ASD, with or without epilepsy and MCA who were admitted to Peking University First Hospital from 2014 to 2019. The results of genetic etiology test of CMA in children with mental retardation or global DD was summarized. Results: Of 1 320 samples, there were 10 cases of aneuploid abnormality, 6 cases of uniparental disomy and one case of mosaicism, respectively. Pathogenic copy number variations (CNVs) were found in 320 cases and pathogenic CNVs were detected in 23 cases, with a combined detection rate of 26% (343/1 320). CNVs of uncertain clinical significance occurred in 107 cases, accounting for 8.1% (107/1 320). There were 25 cases of possible benign CNVs, accounting for 2% (25/1 320), while benign CNVs were reported in 20 cases, accounting for 1.5% (20/1 320). The detection rate of MCA with DD/ID was 39.8% (130/327). Conclusions: CMA has the advantages of high resolution and covering the whole genome. It can detect the chromosomal abnormalities, microdeletions and duplications seen under the microscope, thus the genetic etiology of children with mental retardation or global DD can be diagnosed.

Effects of Early Transplantation of the Faecal Microbiota from Tibetan Pigs on the Gut Development of DSS-Challenged Piglets. BIOMED RESEARCH INTERNATIONAL 2021; 2021:9823969. [PMID: 33532501 PMCID: PMC7837763 DOI: 10.1155/2021/9823969] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Revised: 12/30/2020] [Accepted: 01/06/2021] [Indexed: 12/20/2022]
Abstract
The present study was conducted to investigate the effects of early transplantation of the faecal microbiota from Tibetan pigs on the gut development of dextran sulphate sodium- (DSS-) challenged piglets. In total, 24 3-day-old DLY piglets were divided into four groups (n = 6 per group); a 2 × 2 factorial arrangement was used, which included faecal microbiota transplantation (FMT) (from Tibetan pigs) and DSS challenge. The whole trial lasted for 55 days. DSS infusion increased the intestinal density, serum diamine oxidase (DAO) activity, and colonic Escherichia coli count (P < 0.05), and decreased the Lactobacillus spp. count and mRNA abundances of epidermal growth factor (EGF), glucagon-like peptide-2 (GLP-2), insulin-like growth factor 1 (IGF-1), occludin, mucin 2 (MUC2), regeneration protein IIIγ (RegIIIγ), and interleukin-10 (IL-10) in the colon (P < 0.05). FMT increased the Lactobacillus spp. count and mRNA abundances of GLP-2, RegIIIγ, and IL-10 in the colon (P < 0.05), and decreased the intestinal density, serum DAO activity, and colonic E. coli number (P < 0.05). In addition, in DSS-challenged piglets, FMT decreased the disease activity index (P < 0.05) and attenuated the effect of DSS challenge on the intestinal density, serum DAO activity, and colonic E. coli number (P < 0.05). These data indicated that the faecal microbiota from Tibetan pigs could attenuate the negative effect of DSS challenge on the gut development of piglets.

Abstract
Objective: To investigate the clinicopathological characteristics and the therapeutic effects of signet ring cell carcinoma (SRCC) of rectum and sigmoid colon. Methods: Clinical data and the follow-up information of 29 SRCC patients treated in our tertiary care center from 2008 to 2018 were retrospectively reviewed. The clinicopathological features, diagnostic and therapeutic effects, and the prognostic outcomes were analyzed. Results: Among the 29 patients, 17 were male, 12 were female. The average age was (48.7±14.3) years. Colonoscopy revealed the features of diffuse circumferential thickening of the bowel wall in 20/29 cases (69.0%), while in 9/29 cases (31.0%), endoscopic biopsies showed false negative results. Twenty-five% (4/16) and 17.6% (3/17) lesions were misdiagnosed as the inflammatory changes by endoscopic rectal ultrasonography exam and rectal MRI scan, respectively. Thirteen of the 29 patients received the neoadjuvant chemoradiotherapy (NCRT), 27 patients underwent the radical resection surgeries, and 8 underwent the postoperative radiotherapy. With a median follow-up of 38.5 (3.5-87.0) months, the cumulative 3-years overall survival (OS) rate was 54.0%, and the cumulative 3-years disease-free survival (DFS) rate was 43.0%. The OS rates of patients treated with or without NCRT (non-NCRT) were 46.2% and 69.2%, respectively, without significant difference (P>0.05). The DFS rates of patients treated with or without NCRT were 45.8% and 39.2%, respectively, without significant difference (P>0.05). Parameters including age younger than 40 years and tumor size larger than 5 cm were independent potential risk factors for shortened OS (P<0.05). Conclusions: SRCC of the rectum and sigmoid colon is a rare malignant tumor with special clinical manifestations. It is younger-onset, highly malignant and with very poor prognosis. Therefore, in-depth researches with focus upon the progress of molecular oncology are urgently needed to substantially improve the therapeutic effect of this disease.

Abstract
A comprehensive study of odontoblastic differentiation is essential to understand the process of tooth development and to achieve the ability of tooth regeneration in the future. Zinc finger E-box-binding homeobox 1 (Zeb1) is a transcription factor expressed in various neural crest-derived tissues, including the mesenchyme of the tooth germ. However, its role in odontoblastic differentiation remains unknown. In this study, we found the expression of Zeb1 gradually increased during odontoblast differentiation in vivo, as well as during induced differentiation of cultured primary murine dental papilla cells (mDPCs) in vitro. In addition, the differentiation of mDPCs was repressed in Zeb1-silenced cells. We used RNA sequencing (RNA-seq) to identify the transcriptome-wide targets of Zeb1 and used assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-seq) to explore the direct targets of Zeb1 in both the early stage (embryonic day 16.5; E16.5) and the late stage (postnatal day 0; PN0) of tooth development. We identified the motifs of transcription factors enriched in Zeb1-dependent accessible chromatin regions and observed that only in the early stage of mDPCs could Zeb1 significantly change the accessibility of chromatin regions. In vivo and in vitro experiments confirmed that silencing of Zeb1 at E16.5 inhibited dentinogenesis. Analysis of RNA-seq and ATAC-seq resulted in the identification of Runx2, a gene directly regulated by Zeb1 during early odontoblast differentiation. Zeb1 enhances the expression of Runx2 by binding to its cis-elements, and ZEB1 interacts with RUNX2. In the late stage of tooth development, we found that ZEB1 could directly bind to and increase the enhancer activity of an element upstream of Dspp and promote dentinogenesis. In this study, for the first time, we revealed that ZEB1 promoted odontoblast differentiation in the early stage by altering chromatin accessibility of cis-elements near genes such as Runx2, while in the late stage, it directly enhanced Dspp transcription, thereby performing a dual role.

Abstract
Butyrate is a bioactive molecule produced by the intestinal flora and plays a major role in a variety of inflammatory diseases. Increasing evidence indicates that butyrate can regulate the occurrence and development of atherosclerosis (AS). Coincidentally, it reduces hyperlipidemia and hyperglycemia, which are major risk factors of AS. However, the mechanism by which butyrate regulates the development of AS remains unclear. In this article, we review the effect of butyrate treatment on AS with a focus on the mechanisms of butyrate-mediated modulation of several atherosclerotic processes. These include the improvement of monocyte-endothelial interactions, macrophage lipid accumulation, smooth muscle cell proliferation and migration, and lymphocyte differentiation and function. The existing research indicates that butyrate treatment may be a potentially effective strategy for the prevention of AS. Identity and underlying mechanisms of the molecular pathways of these interactions should be explored in the future to counter AS effectively.

Abstract
OBJECTIVES To determine the risk of poor health-related outcomes in older adults with cooccurring hearing impairment and cognitive impairment, and to compare the risk of hearing impairment only, cognitive impairment only, and multiple morbidities. DESIGN Cross-sectional study. SETTING Community-dwelling older adults aged 60 years and older were included. PARTICIPANTS The data of missing hearing and cognitive status were excluded, and 3770 older people participated in the study. MEASUREMENTS The hearing function evaluation was conducted by questionnaire survey. Assessment of cognitive function was completed using the SPMSQ scale. The subjects were divided into hearing impairment and cognitive impairment group, hearing impairment only group, cognitive impairment only group and neither group. Multiple logistic regression was used to analyze the risks of hearing and cognitive impairment and health-related condition. RESULTS The prevalence of hearing impairment and cognitive impairment, hearing impairment only, cognitive impairment only, and neither were 9.4%, 8.3%, 29.9% and 52.4%, respectively. Compared with the control group, the individuals with hearing impairment and cognitive impairment were associated with depression (OR=3.48, 95% CI=2.66, 4.56), anxiety (OR=2.35, 95% CI=1.92, 3.33), frailty (OR=4.30, 95% CI=2.89, 6.40), and ADL impairment (OR=2.77, 95% CI=2.03, 3.77). CONCLUSION The studies shows that hearing impairment combined with cognitive impairment is significantly associated with anxiety, depression, frailty, and ADL impairment. Comprehensive management and intervention should be provided for older people to reduce the occurrence of adverse health consequences.

Abstract
OBJECTIVE To analyze the changing tendency in the endemic situation of schistosomiasis in the national surveillance sites of Hubei Province, so as to provide the scientific evidence for facilitating the progress towards the elimination of schistosomiasis in the province. METHODS According to the National Schistosomiasis Surveillance Scheme (2014 version), a total of 65 national schistosomiasis surveillance sites were assigned in Hubei Province, and the Schistosoma japonicum infections in humans, domestic animals, snails and wild feces were monitored in these national surveillance sites from 2015 to 2019. All data pertaining to the surveillance results were descriptively analyzed. RESULTS There were 151 159 person-time local residents and 70 928 person-time mobile populations screened for S. japonicum infections in the 65 national surveillance sites of Hubei Province from 2015 to 2019, and the seroprevalance of S. japonicum infections reduced from 3.45% (1 077/31 197) in 2015 to 1.57% (431/27 371) in 2019 among local residents and from 1.06% (98/9 249) in 2015 to 0.81% (116/14 318) in 2019 among mobile populations. During the period from 2015 through 2019, there were 22 egg-positive local residents and 2 egg-positive mobile populations identified in 2015, with 0.07% and 0.02% prevalence rates of S. japonicum infections, respectively. During the 5-year period, a total of 7 025 herd-time domestic animals examined for S. japonicum infections, with no infections detected, and a total of 2 035 wild feces were tested, with no egg-positives identified in the 65 national surveillance sites of Hubei Province. Snail survey was conducted covering 28 767.35 hm2 during the 5-year period, and the area of snail habitats ranged from 1 609.82 to 2 119.81 hm2. The mean density of living snails and occurrence of frames with snails reduced from 0.360 5 snails/0.1 m2 and 11.26% in 2015 to 0.175 9 snails/0.1 m2 and 8.43% in 2019, respectively, and no S. japonicum infection was found in snails during the 5-year period. In addition, no snails were found in the potential schistosomiasis transmission foci in the two national surveillance sites in the Three Gorges Dam. CONCLUSIONS The overall endemic situation of schistosomiasis appears a tendency towards a decline in Hubei Province during the period from 2015 through 2019; however, the schistosomiasis transmission risk remains. Improving the surveillance system of schistosomiasis and increasing the sensitivity and performance of the surveillance system are required to provide insights into the implementation of precision control strategy and interventions in Hubei Province.

Abstract
OBJECTIVE To investigate the effects of long non-coding ribonucleic acid (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) on myocardial ischemia/reperfusion (I/R) injury in rats and its mechanism, and to provide a certain reference for the clinical prevention and treatment of myocardial infarction. MATERIALS AND METHODS A total of 60 male Sprague-Dawley rats were divided into 3 groups using a random number table, including the Sham group (n=20), I/R group (n=20) and I/R + MALAT1 small interfering RNA (siRNA) group (n=20). An I/R model was established by means of recanalization after ligation of the left anterior descending coronary artery of the rats. The rats in the I/R + MALAT1 siRNA group were used to establish a model of MALAT1 knockdown by injecting MALAT1 siRNA from the tail vein. The myocardial infarction area in each group was detected via 2,3,5-triphenyl tetrazolium chloride (TTC) staining. The ejection fraction% (EF%) and fractional shortening% (FS%) of the heart in each group were measured through echocardiography. Hematoxylin and eosin (H&E) staining was adopted to determine the morphological changes in myocardial cells in each group. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining was performed to detect the apoptosis levels of myocardial cells and fibroblasts in the cardiac tissues in each group, and Western blotting assay was conducted to measure the expression levels of apoptosis-related proteins [B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax)]. In addition, the content of β-catenin in the three groups of rats was determined via immunohistochemical staining. Finally, the impacts of MALAT1 siRNA on the expression level of β-catenin protein were detected using Western blotting assay. RESULTS MALAT1 siRNA could prominently ameliorate the I/R-induced cardiac insufficiency in the rats and improve the EF% and FS% of the heart (p<0.05). Moreover, MALAT1 siRNA was able to remarkably inhibit the I/R injury-induced myocardial infarction, reducing the infarction area from (59.54±3.45) to (24.85±1.30; p<0.05). The results of the H&E staining indicated that compared with those in the I/R group, the myofilaments of the myocardial cells were well-arranged, the degrees of degradation and necrosis of the myofilaments declined, and the cellular edema was relieved markedly in the I/R + MALAT1 siRNA group. It was shown in the results of immunohistochemistry and Western blotting that MALAT1 siRNA could notably reverse the I/R-induced up-regulation of β-catenin expression (p<0.05). CONCLUSIONS MALAT1 knockdown can significantly ameliorate the I/R-induced myocardial injury and improve the cardiac function of the rats, whose mechanism is probably correlated with the inhibition of MALAT1 siRNA on β-catenin. Therefore, MALAT1 siRNA is expected to become a new target for the treatment of myocardial infarction.

Abstract
In this study, the performance and mechanism of nitrogen removal in sequencing batch reactors (SBRs) with and without zero-valent iron (ZVI) was investigated. The results showed that ZVI had a capacity to promote NH4+-N conversion, NO2--N accumulation and total inorganic nitrogen (TIN) removal, with the TIN removal rate being increased by 29.45%. The ZVI also had a significant impact on microbial community structure by means of high-throughput pyrosequencing, increasing the enrichment of Anammox (anaerobic ammonium oxidation) bacteria Candidatus Brocadia and Feammox (anaerobic ferric ammonium oxidation) bacteria Ignavibacterium. With ZVI addition, the main pathway of nitrogen removal was changed from nitrification-heterotrophic denitrification to Anammox and Feammox.

Abstract
AIMS To examine the association between 24 literature-based single nucleotide polymorphisms and diabetic kidney disease in Chinese people with type 2 diabetes. METHODS AND RESULTS Twenty-four candidate diabetic kidney disease-susceptible single nucleotide polymorphisms were genotyped in 208 participants with type 2 diabetes and diabetic kidney disease and 200 participants with type 2 diabetes without diabetic kidney disease (case and control groups, respectively), together with 206 healthy participants using MassARRAY. Rs11643718 in the SLC12A3 gene was associated with diabetic kidney disease in the recessive model after adjusting for confounding factors, such as age and gender (adjusted odds ratio 2.056, 95% CI 1.120-3.776; P = 0.020). Meta-analyses further confirmed the association (P = 0.002). In addition, participants with the GG genotype had worse renal function and more albuminuria than those with the AA+AG genotype (P < 0.05). Renal section immunohistochemistry was conducted in participants with type 2 diabetes, diabetic kidney disease and AA+AG or GG genotypes and in participants with glomerular minor lesions. Together with data from the Nephroseq database, it was shown that the abundance of SLC12A3 was reduced in patients with the GG genotype, while elevated expression of SLC12A3 was associated with better renal function. In addition, rs10951509 and rs1345365 in ELMO1, which were determined to be in high linkage disequilibrium by SHEsis software, were also associated with diabetic kidney disease (adjusted P = 0.010 and 0.015, respectively). CONCLUSIONS The G allele and GG genotype of SLC12A3 rs11643718 are associated with the development of diabetic kidney disease in a Chinese population with type 2 diabetes.

Abstract
Objective: To investigate the workplace violence and compassion fatigue of nurses in emergency department and to explore the relationship between the two. Methods: The general information questionnaire, workplace violence scale and professional quality of life scale were used to investigate 957 emergency department nurses of 28 Level II hospitals and above. Results: The scores of each dimension of the professional quality of life scale for nurses in the emergency department were: compassion satisfaction score was 29.91±7.82, the burnout score was 26.63±5.66, and the second trauma score was 23.17±5.94. The total score of compassion fatigue is 49.80±10.42. The incidence of workplace violence was 77.6%. Workplace violence was negatively correlated with compassion satisfaction (r=-0.250, P<0.01) , and positively correlated with burnout, secondary trauma, and total compassion fatigue (r=0.349、0.340、0.384, P<0.01) . Whether there is only non-physical violence in the compassion satisfaction, burnout, secondary trauma, compassion fatigue total score is not statistically significant. Conclusion: Compassion fatigue is more serious in emergency department nurses, and the incidence of workplace violence is higher. Workplace violence has a positive effect on compassion fatigue. Nursing managers should actively prevent workplace violence and improve the working environment, thus reducing empathy fatigue.
