Abstract
OBJECTIVE The activation of autophagy was shown to shrink infarct size and mitigate cardiac dysfunction caused by myocardial infarction (MI). However, the underlying mechanisms remain largely unknown. As excessive generation of reactive oxygen species (ROS) deteriorates MI process and Nrf2 signaling exerts an antioxidant role, we explored whether autophagy assuaged MI through Nrf2 signaling activation-mediated ROS clear. MATERIALS AND METHODS MI models were induced by ligation of the left descending coronary artery (LAD) in C57BL/6J mice or Nrf2 knockout mice (Nrf2-KO). Rapamycin and 3-methyladenine (3-MA) were used to activate and repress autophagy in MI mice, respectively. Aspirin, a cardioprotective drug was given to MI mice to evaluate its effects on autophagy. RESULTS Compared with the MI group, rapamycin treatment remarkably decreased the infarct size, cell apoptosis and blood troponin I level, accompanied by reduced redox potential (Eh), ROS, malondialdehyde (MDA) and cytochrome C levels, and increased reduced glutathione (GSH) level. Also, rapamycin treatment increased the expressions of bcl-2, bcl-xL, HSP70, and HSP90. In addition, rapamycin treatment promoted the nuclear accumulation of Nrf2 protein. However, Nrf2 downregulation significantly impaired the effects of rapamycin on the reductions of infarct size, cell apoptosis, troponin I and ROS levels. Similarly, to rapamycin roles, aspirin treatment also remarkably reduced infarct size, cell apoptosis and troponin I in mice with MI surgery, as well as increased the expression level of LC3II/LC3I. CONCLUSIONS This study demonstrated that autophagy enhancement contributed to the improvement of MI through Nrf2 signaling activation-mediated ROS clear.

Abstract
OBJECTIVE Gastric carcinoma is one of the most common malignant tumors and one of the most common cancer-related fatal diseases. Chemotherapy is considered as the major therapy for advanced gastric cancer, and the curative effect of chemotherapy directly affects the treatment of advanced gastric cancer. Drug resistance of tumor cells is one of the important causes that induces failure of chemotherapy. Previous studies have demonstrated that verapamil (VER) can reverse drug resistance by inhibiting the P-glycoprotein (P-gp), which is one of the main targets of VER. The present study aimed at investigating the function of glucosylceramide synthase (GCS) in the VER-induced reversal of doxorubicin (ADM) chemotherapy resistance in gastric carcinoma. PATIENTS AND METHODS In the current study, the 4 GC cell line was selected for investigation. The IC50 values of gastric cancer cells were measured using CCK-8 assay. The expression levels of candidate genes in gastric carcinoma cells were measured by RT-qPCR. The expression levels of candidate protein in gastric carcinoma cells were measured by Western blot. The expression of GCS protein in clinical specimens of GC receiving VER+TACE therapy was measured by immunohistochemistry. The test of gastric carcinoma cell apoptosis was measured by Annexin V-FITC/PI double-staining. RESULTS We found that the expression levels changes of the GCS gene can influence the effects of ADM+VER on cell apoptosis. The role and mechanism of GCS gene in reversing the chemotherapy resistance of gastric carcinoma cells to ADM were explored. CONCLUSIONS In future research, we will explore the mechanism of how GCS affects drug resistance in gastric carcinoma and related signal transduction pathway.

Abstract
BACKGROUND Runt-related transcription factor 2 (RUNX2) is an important gene that has been implicated in the progression of human cancer. Aberrant expression of RUNX2 predicts gastric cancer (GC) metastasis. However, the molecular mechanism of RUNX2 remains unknown. OBJECTIVE We hypothesize that RUNX2 promotes GC metastasis by regulating the extracellular matrix component collagen type I alpha 1 (COL1A1). METHODS The GEPIA database and immunohistochemical staining of 60 GC tissues were used to analyse the correlations between RUNX2 or COL1A1 expression and clinicopathological features, and the Kaplan-Meier method was used to evaluate survival. RT-PCR, western blotting and immunofluorescence were used to detect RUNX2 and COL1A1 expression in GC cells. Migration and invasion assays were performed to assess the influence of RUNX2 and COL1A1 on metastasis. RESULTS RUNX2 and COL1A1 were highly expressed at both the gene and protein levels in GC, and patients who were positive for RUNX2 and COL1A1 had shorter survival. RUNX2 and COL1A1 expression linearly correlated with each other (r= 0.15, p< 0.01) and with clinical stage and lymph node metastasis (p< 0.05). Overexpressing RUNX2in vitro enhanced COL1A1 expression and promoted GC cell invasion and migration, whereas COL1A1 knockdown inhibited the increase in cell metastatic capacity promoted by RUNX2. In vivo, GC cells overexpressing RUNX2 promoted lung metastasis, and the downregulation of COL1A1 reduced the metastasis promoted by RUNX2. CONCLUSIONS RUNX2 may promote GC metastasis by regulating COL1A1. RUNX2/COL1A1 can be employed as a novel target for therapy in GC.

Abstract
Pancreatic cancer is considered to be the most malignant digestive tract tumor due to its high invasiveness, metastasis and recurrence rate. In recent years, neoadjuvant therapy has brought new insights to the treatment of pancreatic cancer. To date, the value of neoadjuvant therapy in pancreatic cancer has been widely recognized, but there is a lack of specific regimens. The superiority and inferiority of various regimens are still uncertain, therefore, the efficacy of neoadjuvant therapy can be evaluated combined with imaging, functional and biological markers.

Abstract
OBJECTIVE The immunoscore, which is used to quantify immune infiltrates, has greater relative prognostic value than tumor, node, and metastasis (TNM) stage and might serve as a new system for classification of colorectal cancer. However, a comparable immunoscore for predicting lung adenocarcinoma (LUAD) prognosis is currently lacking. METHODS We analyzed the expression of 18 immune features by immunohistochemistry in 171 specimens. The relationship of immune marker expression and clinicopathologic factors to the overall survival (OS) was analyzed with the Kaplan-Meier method. A nomogram was developed by using the optimal features selected by least absolute shrinkage and selection operator (LASSO) regression in the training cohort (n = 111) and evaluated in the validation cohort (n = 60). RESULTS The indicators integrated in the nomogram were TNM stage, neuron-specific enolase, carcino-embryonic antigen, CD8center of tumor (CT), CD8invasive margin (IM), FoxP3CT, and CD45ROCT. The calibration curve showed prominent agreement between the observed 2- and 5-year OS and that predicted by the nomogram. To simplify the nomogram, we developed a new immune-serum scoring system (I-SSS) based on the points awarded for each factor in the nomogram. Our I-SSS was able to stratify same-stage patients into different risk subgroups. The combination of I-SSS and TNM stage had better prognostic value than the TNM stage alone. CONCLUSIONS Our new I-SSS can accurately and individually predict LUAD prognosis and may be used to supplement prognostication based on the TNM stage.

Abstract
Accumulating evidence has revealed that long noncoding RNAs (lncRNAs) play essential roles in regulating cellular process of various cancers. There have been many studies on the biological functions of lncRNAs in colorectal cancer (CRC). In this research, we explored the role and mechanism of lncRNA ovarian tumor domain containing 6B antisense RNA1 (OTUD6B-AS1) in CRC. Here, we detected OTUD6B-AS1 expression in CRC tissues and cells by RT-qPCR. Functional experiments were performed to test alterations in different cellular processes. Moreover, to verify the binding ability among the indicated RNA molecules, we carried out RIP, RNA pull-down and luciferase reporter assays. According to our data, OTUD6B-AS1 expression was low in CRC tissues and cells. Functionally, overexpression of OTUD6B-AS1 inhibited cell proliferation, migration, invasion and EMT, and promoted cell apoptosis. Bioinformatic analysis and mechanistical experiments confirmed that OTUD6B-AS1 could act as a competitive endogenous RNA (ceRNA) to upregulate Proline-Rich Nuclear Receptor Coactivator 2 (PNRC2) expression by sequestering miR-21-5p. Further rescue experiments validated the inhibitory function of the OTUD6B-AS1/miR-21-5p/PNRC2 axis in cellular process of CRC. Overall, OTUD6B-AS1 inhibits cellular development in CRC by sponging miR-21-5p and upregulating PNRC2, providing a novel insight into the exploration on CRC treatment.

Abstract
OBJECTIVE Recently, breast cancer (BC) has become a common tumor that threatens the physical and mental health of women. Microribonucleic acids (miRNAs) have been chosen as a study object because of their roles in various cancers, including BC. Here, we mainly study the role of miR-15b in BC progression and its underlying mechanism. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was performed to examine the level of MiR-15b expression in 60 pairs of BC tissues and para-cancerous specimens, and the relationship between MiR-15b level and clinical features of BC patient prognosis was analyzed. MiR-15b and PAQR3 level in BC tissues and cells was tested by Western blot. RESULTS The results showed that miR-15b expression was higher and PAQR3 level was lower in BC. The identification of PAQR3 as a target of miR-15b in BC was carried out by Luciferase reporter assay and the results stated that the Luciferase activity was reduced by miR-15b mimic, indicating PAQR3 being a target of miR-15b in BC. Transwell assay was used for examining BC cell migration and invasion and found that miR-15b could promote BC cell migration and invasion, while the effect of PAQR3 was inhibition. Furthermore, PAQR3 could reverse the promotion effect of miR-15b on BC cell migratory and invasive ability. In addition, miR-15b expression was negatively correlated with PAQR3 performed by regression analysis. CONCLUSIONS Our data stated that miR-15b could facilitate BC progression via repressing tumor suppressor PAQR3, indicating that miR-15b/PAQR3 axis provided a therapeutic target for treating BC.

Abstract
OBJECTIVE Prostate cancer is one of the most ordinary malignant tumors. Recently, the role of long non-coding RNAs (lncRNAs) in tumor progression has caught the attention of numerous researchers. In this work, lncRNA SNHG14 was studied to identify how it functioned in the progression of prostate cancer. PATIENTS AND METHODS First, Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was utilized to measure SNHG14 expression in prostate cancer tissues and cell lines. Furthermore, to identify the function of SNHG14 in prostate cancer, functional experiments were conducted in vitro and in vivo. In addition, by performing Luciferase assays and RNA immunoprecipitation assay (RIP), the underlying mechanism was explored. RESULTS In this work, SNHG14 expression was remarkably higher in prostate cancer samples when compared with that in the corresponding ones. Moreover, cell proliferation was inhibited after SNHG14 was silenced in prostate cancer cells and the expression of miR-613 was upregulated after SNHG14 was silenced. Further mechanism assays showed that miR-613 was a direct target of SNHG14 in prostate cancer. In addition, tumor formation was inhibited after SNHG14 was knocked-down in vivo. CONCLUSIONS Our study discovers a potential oncogene in prostate cancer and identifies that SNHG14 enhances cell proliferation via sponging miR-613.

Abstract
OBJECTIVE To study the effect of RBMS3 on nucleus pulposus cells and its effect on the Wnt/β-catenin signaling pathway. PATIENTS AND METHODS We measured the expression of RBMS3 in human nucleus pulposus tissues with different degrees of degeneration. Recombinant human IL-1β is used to stimulate the degeneration of human nucleus pulposus cells. We used Wnt/β-catenin signaling pathway inhibitors and cell transfection to study the effect of RBMS3 on nucleus pulposus cells and its mechanism. RESULTS RBMS3 was less expressed in the nucleus pulposus tissue of people with higher degeneration degree. IL-1β reduced the expression of RBMS3 in nucleus pulposus cells. Overexpression of RBMS3 can promote the proliferation of nucleus pulposus cells and reduce the apoptosis and inflammation of cells. In addition, RBMS3 can reduce the expression of β-catenin and c-myc in nucleus pulposus cells, and inhibit the activity of the Wnt/β-catenin signaling pathway. CONCLUSIONS RBMS3 inhibits the Wnt/β-catenin signaling pathway, improves the proliferation ability of nucleus pulposus cells, inhibits their apoptosis and inflammation, and thus delays the degeneration of the intervertebral disc.

Abstract
Objective: To analyze the prevalence and the related factors of dyslipidemia in 21-hydroxylase deficiency (21-OHD) patients. Methods: A total of 205 patients with 21-OHD were recruited in Peking Union Medical College Hospital from January 2016 to January 2018. The basic information, glucocorticoid replacement therapy, and laboratory examination results of patients were obtained from medical records. The genotypes of CYP21A2 were identified by Sanger sequencing and multiplex ligation dependent probe amplification. The prevalence of dyslipidemia among 21-OHD patients, basic information and related hormone levels of 21-OHD patients with different status of blood lipid were described. Logistic regression model was used to analyze the related factors of dyslipidemia in 21-OHD patients. Results: The age of subjects was 17.0 (8.3, 25.0) years old, including 51 males (24.9%). According to CYP21A2 genotypes, there were 16 cases in Null group, 26 cases in Group A, 105 cases in group B, 27 cases in group C, and 31 cases in group D. The incidence of dyslipidemia was 29.3% (60/205), among which 37.3% (19/51) in male and 26.6% (41/154) in female patients, respectively. The M (Q1, Q3) of total cortisol level (nmol/L) and body mass index (kg/m2) of male 21-OHD patients with dyslipidemia were 0.17 (0.06, 0.35) and 25.76 (17.01, 30.45), respectively, which were higher than those with ortholiposis [0.04 (0.02, 0.21) and 18.83 (16.53, 23.88)] (all P<0.05). The M (Q1, Q3) of progesterone level (nmol/L), body mass index (kg/m2) and age (years) of female 21-OHD patients with dyslipidemia were 74.40 (50.97, 98.52), 23.09 (21.78, 27.78) and 23.00 (16.50, 28.00), respectively, which were higher than those with ortholiposis [52.81 (33.41, 68.85), 21.55 (18.63, 25.71) and 18.00 (9.50, 25.00)] (all P<0.05). The risk of dyslipidemia increased by 5.0% [OR (95%CI): 1.05 (1.01, 1.09)] for every 1 nmol/L increase of progesterone. Conclusion: The incidence of dyslipidemia is high in 21-OHD patients, and progesterone level is positively correlated with dyslipidemia.

Abstract
MicroRNAs serve as potential biomarkers in various pathological models, and are stable and detectable in biofluids. We investigated the urinary microRNA expression profile in a gentamicin-induced acute kidney injury canine model using RNA sequencing. A total of 234 differentially expressed microRNAs were screened after 12 consecutive days of gentamicin administration (P < 0.05). Six candidate microRNAs (miR-15b, -15b-3p, -16, -30a, -30a-3p, and -30c-2-3p) were selected according to a set criterion, and validated by real-time quantitative PCR. The diagnostic values of these six candidate microRNAs were better than the traditional serum biomarkers (all P < 0.05). Further, using receiver operating characteristic curve analysis, we found that miR-15b and -15b-3p were superior to urinary kidney injury molecule-1 (both P < 0.05). Moreover, miR-15b and -30a levels in the urine samples significantly correlated with their respective levels in the kidney tissue samples (r=0.512 and 0.505, respectively, both P < 0.05). Our data concluded that miR-15b and -30a may be promising biomarkers for renal toxicity.

Abstract
Abstract
Background
The early diagnosis of cardiac syncope is often challenging. We therefore developed an ECG-based risk calculator as an aid for rapid rule-out or rule-in of cardiac syncope and aimed to validate this decision tool.
Methods
In a prospective diagnostic international multicenter study (derivation cohort), 2007 patients, 40 years or older, presenting with syncope to the emergency department were recruited. The primary diagnostic outcome, cardiac syncope, was centrally adjudicated by two independent cardiologists using all clinical information obtained during syncope work-up including 12-month follow up. 12-lead ECG was recorded at presentation and read by residents blinded to clinical information. Significant ECG predictors of cardiac syncope were identified using penalized backward selection. Findings were validated in an independent US multicenter cohort with 2'269 syncope patients.
Results
In the derivation cohort (median age 71 years, 40% women), centrally adjudicated cardiac syncope was present in 267 patients (16%). Seven ECG criteria (rhythm, heart rate, corrected QT-interval, ST-segment depression, atrioventricular-block, bundle-branch-block and ventricular extrasystole/non-sustained ventricular tachycardia) were identified as significant predictors for cardiac syncope and combined into the bAseL Ecg Risk calculaTor for Cardiac Syncope (ALERT-CS). Diagnostic accuracy of ALERT-CS for cardiac syncope, as quantified by the area under the receiver-operating characteristics curve (AUC), was high (0.80, 95%-confidence interval (CI) 0.77–0.83) and significantly higher compared to the EGSYS score (0.73, 95% CI 0.70–0.76, p<0.001). In combination, ALERT-CS significantly increased the AUC of BNP (0.82, 95% CI 0.79–0.85 vs 0.77, 95% CI 0.74–0.81, p=0.003), hs-cTnT (0.84, 95% CI 0.0.81–0.87 vs 0.77, 95% CI 0.74–0.80, p<0.001) and integrated clinical judgment in the ED (0.90, 95% CI 0.89–0.92 vs 0.87, 95% CI 0.84–0.90, p<0.001).
A predicted probability for cardiac syncope below 5.5% by ALERT-CS identified 138 patients (8%) eligible for triage towards rapid rule-out of cardiac syncope with a sensitivity of 99%. A predicted probability above 37.5% identified 181 patients (11%) eligible for triage towards rapid rule-in of cardiac syncope with a specificity of 95%. Prognostic verification for 30-day major adverse cardiac events (MACE) showed a high rate of MACE in the rule-in group and a very low rate of MACE in the rule-out group (Figure).
External validation (median age 72 years, 48% women) showed similar diagnostic accuracy (AUC 0.76, 95% CI 0.73–0.79) and prognostic results.
Conclusion
Combining seven ECG criteria within the simple ALERT-CS may aid ED physicians in the early rule-out or rule-in of cardiac syncope.

Abstract
Abstract
Background
Data on changes in left atrial (LA) and left ventricular (LV) volumes after transcatheter mitral valve replacement (TMVR) are limited.
Purpose
This study sought to describe the anatomical and functional changes in left-sided cardiac chambers by computed tomography angiography (CTA) from baseline to 1-month after TMVR with Tendyne prosthesis.
Methods
We analyzed patients who underwent TMVR with Tendyne prosthesis (Abbott Structural, Menlo Park, CA) between 2015 and 2018. Changes in LV end-diastolic volume (LVEDV), ejection fraction (LVEF), mass (LV mass), LA volume and global longitudinal strain (GLS) were assessed at baseline and at 1-month after TMVR with CTA. Specific Tendyne implant characteristics were identified and correlated with remodeling changes.
Results
A total of 36 patients (mean age 73±8 years, 78% men, 86% secondary MR) were studied. There were significant decreases in LVEDV (268±68 vs. 240±66ml, p<0.001), LVEF (38±10 vs. 32±11%, p<0.001), LV mass (126±37 vs. 117±32g, p<0.001), LA volume (181±74 vs. 174±70 ml, p=0.027) and GLS (−12.6±5.1 vs. −9.5±4.0%, p<0.001) from baseline to 1-month follow-up. Favorable LVEDV reverse-remodeling occurred in the majority (30 of 36 patients, or 83%). Closer proximity of the Tendyne apical pad to the true apex was predictive of favorable remodeling (pad distance: 25.0±7.7 vs. 33.5±8.8mm, p=0.02 for those with and without favorable remodeling).
Conclusions
TMVR with Tendyne results in favorable left-sided chamber remodeling in the majority of patients treated, as detected on CTA at 1-month after implantation. CTA identifies the favorable post-TMVR changes, which could be related to specific characteristics of the device implantation.

Abstract
Objective: To examine the effect of the "four-steps" treatment on infectious pancreatic necrosis(IPN). Methods: The data of 207 patients who were diagnosed with IPN from January 2013 to December 2017 at Department of Pancreaticobiliary Surgery, the First Affiliated Hospital of Harbin Medical University were analyzed retrospectively. Among 207 patients, 132(63.8%) were males and 75(36.2%) were females. The median age was 45 years old (range: 19 to 80 years old). One hundred and fifty-eight patients(76.3%) suffered severe acute pancreatitis and 49 patients(23.7%) suffered moderately severe acute pancreatitis. Percutaneous catheter drainage(PCD) was performed on all the patients(Step 1). Patients received "four-steps" minimally invasive treatment strategy in step-up group(173 patients). The following steps after PCD were mini-incision access pancreatic necrosectomy(MIAPN) (Step 2), sinus tract endoscopic debridement and(or) PCD for residual infections(Step 3) and finally conventional open pancreatic necrosectomy(OPN) (Step 4). Patients(34 cases) received conventional open pancreatic necrosectomy after invalided PCD in OPN group. The perioperative parameters and prognosis were compared between Step-up group and OPN group. Normally distributed quantitative variables were analyzed by t-test, non-normally distributed quantitative variables were analyzed by Wilcoxon chi-square test and categorical variables were analyzed by χ(2) test or Fisher exact test, respectively. Results: The basic characteristics of the two groups of patients were similar, but the referral rate of patients and the rate of preoperative 3 days organ failure in the OPN group were significantly higher than those of step-up group patients(47.1% vs. 28.9%, χ(2)=4.313, P=0.038; 26.5% vs. 9.2%, χ(2)=2.819, P=0.011). The frequency of PCD and the number of PCD tube (root) were less than those in the step-up group(1(1) vs. 2(1), Z=-3.373, P=0.018; 2(1) vs. 3(2), Z=-2.208, P=0.027). Compared with the OPN group, the interval time from onset to surgery and the MIAPN operation time were significantly shorter in the step-up group(29(15) days vs. 36(17)days, Z=-0.567, P=0.008; 58(27)minutes vs. 90(56)minutes, Z=-3.908, P<0.01); postoperative mortality was lower(5.8% vs.17.6%, χ(2)=4.070, P=0.044); the overall incidence of postoperative complications was reduced(23.1% vs. 55.9%, χ(2)=14.960, P<0.01) and the incidence of new-onset organ failure was decreased after operation in the step-up group(37.5% vs.47.4%, χ(2)=7.133, P=0.007). The incidence of local abdominal complications (pancreatic fistula, intra-abdominal hemorrhage, gastrointestinal fistula) showed no significant difference between the two groups (P>0.05). Fewer patients required ICU treatment after operation in the step-up group compared with OPN group(22.0% vs. 44.1%, χ(2)=6.204, P=0.013). Patients in the Step-up group has shorter hospital stay than patients in OPN group (46(13) days vs. 52(13)days, Z=-1.993, P=0.046). Conclusions: The clinical effects of "four-steps" exhibited the superiority of minimally invasive treatment of IPN.And MIAPN is a simple, safe and effective procedure to remove pancreatic necrotic tissue and decrease complications.

Abstract
Objective: To evaluate the clinical characteristics and prognosis of gallbladder cancer (GBC) patients in China. Methods: This retrospective multicenter cohort study enrolled 3 528 consecutive GBC patients diagnosed between January 2010 to December 2017 in 15 hospitals from 10 provinces. There were 1 345 (38.12%) males and 2 183 (61.88%) females.The age of diagnosis was (63.7±10.8) years old (range: 26 to 99 years old) .There were 213 patients (6.04%) in stage 0 to Ⅰ, whereas 1 059 (30.02%) in stage Ⅱ to Ⅲ, 1 874 (53.12%) in stage Ⅳ, and 382 (10.83%) unavailable. Surgery was performed on 2 255 patients (63.92%) . Three hundred and thirty-six patients received chemotherapy or radiotherapy (9.52%; of which 172 were palliative); 1 101 (31.21%) received only supportive treatment.The patient source, treatment and surgery, pathology, concomitant gallstone, and prognosis were analyzed. Results: Among the 3 528 GBC patients, 959 (27.18%) were from East China, 603 (17.09%) from East-North China, 1 533 (43.45%) from Central China, and 433(12.27%) from West China. Among the 1 578 resectable tumor, 665 (42.14%) underwent radical surgery, 913 (57.86%) underwent surgery that failed to follow the guidelines.Eight hundred and ninety-one (56.46%) patients were diagnosed before surgery, 254 (16.10%) during surgery, and 381 (24.14%) after surgery (time point of diagnosis couldn't be determined in 52 patients) .Among the 1 578 patients with resectable tumor, 759 (48.10%) had concomitant gallstone.Among the 665 patients underwent radical surgery, 69 (10.4%) showed positive resection margin, 510 (76.7%) showed negative resection margin, and 86 (12.9%) unreported margin status.The 5-year overall survival rate (5yOS) for the 3 528-patient cohort was 23.0%.The 5yOS for patients with resectable tumor was 39.6%, for patients with stage ⅣB tumor without surgery was 5.4%, and for patients with stage ⅣB tumor underwent palliative surgery was 4.7%. Conclusions: More than half GBC patients in China are diagnosed in stage Ⅳ.Curative intent surgery is valuable in improving prognosis of resectable GBC.The treatment of GBC needs further standardization.Effective comprehensive treatment for GBC is in urgent need.

Abstract
The diagnosis of coronavirus 19 (COVID-19) relies mainly upon viral nucleic acid detection, but false negatives can lead to missed diagnosis and misdiagnosis; severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific antibody detection is convenient, safe and highly sensitive. Immunoglobulin (Ig)M and IgG are commonly used to serologically diagnose COVID-19; however, the role of IgA is not well known. We aimed to quantify the levels of SARS-CoV-2-specific IgM, IgA and IgG antibodies, identify changes in them based on COVID-19 severity, and establish the significance of combined antibody detection. COVID-19 patients, divided into a severe and critical group and a moderate group, and non-COVID-19 patients with respiratory disease were included in this study. A chemiluminescence method was used to detect the levels of SARS-CoV-2-specific IgM, IgA and IgG in the blood samples from the three groups. Epidemiological characteristics, symptoms, blood test results and other data were recorded for all patients. Compared to the traditional IgM-IgG combined antibodies, IgA-IgG combined antibodies are more effective for diagnosing COVID-19. During the disease process, IgA appeared first and disappeared last. All three antibodies had significantly higher levels in COVID-19 patients than in non-COVID-19 patients. IgA and IgG were also higher for severe and critical disease than for moderate disease. All antibodies were at or near low levels at the time of tracheal extubation in critical patients. Detection of SARS-CoV-2-specific combined IgA-IgG antibodies is advantageous in diagnosing COVID-19. IgA detection is suitable during early and late stages of the disease. IgA and IgG levels correspond to disease severity.

Abstract
Objective: To describe the clinical characteristics and treatment of severe community-acquired pneumonia(SCAP) caused by Legionella pneumophila with acute respiratory failure and to analyze the risk factors for mortality. Methods: From October 2011 to October 2019, 34 patients were diagnosed with SCAP caused by Legionella pneumophila with acute respiratory failure.There were 25 males and 9 females, aged from 17 to 82 years, with a median age of 61 (48, 69) years. According to the prognosis, the patients were divided into a survival group and a death group for comparative analysis.The survival group included 24 patients, 17 males and 7 females, with a median age of 65 (55, 70) years. There were 10 cases in the death group, 8 males and 2 females, with a median age of 53 (50, 58) years. Multivariable logistic regression analysis was used for risk factors of ICU mortality. Results: The median time of admission to ICU was 7 (5, 11) days, the median time of stay in RICU was 12 (7, 22) days, and the PaO(2)/FiO(2) was 134 (91, 216) mmHg(1 mmHg=0.133 kPa). Ten patients died during ICU hospitalization, with a mortality of 29%. Sequential organ failure assessment (SOFA) of death group was 9 (7, 12), which was significantly higher than that of the survival group [4 (3, 8)], P=0.018. The time from onset of pneumonia symptoms to initiation of targeted treatment of the death group was 10 (7, 14) d, which was significantly longer than that of the survival group of [4 (3, 7) d], P=0.019. Multivariable logistic regression analysis showed that SOFA score (OR=1.461, 95%CI 1.041-2.051, P=0.028) and the time from onset of pneumonia symptoms to initiation of targeted treatment (OR=1.293, 95%CI 1.029-1.625, P=0.027) were independent risk factors for hospital mortality. Conclusions: The ICU mortality of severe legionella pneumonia was high. Critical organ dysfunctions and delayed initial targeted treatment were related with the increase of ICU mortality.

Abstract
The up-regulation of EMT regulator Twist1 has been implicated in vasculogenic mimicry (VM) formation in human triple-negative breast cancer (TNBC). Twist1 targets the Claudin15 promoter in hepatocellular carcinoma cells. Claudin family members are related with TNBC. However, the relationship between Claudin15 and VM formation is not clear. In this study, we first found that Claudin15 expression was frequently down-regulated in human TNBC, and Claudin15 down-regulation was significantly associated with VM and Twist1 nuclear expression. Claudin15 down-regulation correlated with shorter survival compared with high levels. Claudin15 silence significantly enhanced cell motility, invasiveness and VM formation in the non-TNBC MCF-7 cells. Conversely, an up-regulation of Claudin15 remarkably reduced TNBC MDA-MB-231 cell migration, invasion and VM formation. We also showed that down-regulation of Claudin15 was Twist1-dependent, and Twist1 repressed Claudin15 promoter activity. Furthermore, GeneChip analyses of mammary glands of Claudin15-deficient mice indicated that Claudin18 and Jun might be downstream factors of Twist1-Claudin15. Our results suggest that Twist1 induced VM through Claudin15 suppression in TNBC, and Twist1 inhibition of Claudin15 might involve Claudin18 and Jun expression.

Abstract
Colonoscopy is commonly used to screen for colorectal cancer (CRC). We develop a deep learning model called CRCNet for optical diagnosis of CRC by training on 464,105 images from 12,179 patients and test its performance on 2263 patients from three independent datasets. At the patient-level, CRCNet achieves an area under the precision-recall curve (AUPRC) of 0.882 (95% CI: 0.828-0.931), 0.874 (0.820-0.926) and 0.867 (0.795-0.923). CRCNet exceeds average endoscopists performance on recall rate across two test sets (91.3% versus 83.8%; two-sided t-test, p < 0.001 and 96.5% versus 90.3%; p = 0.006) and precision for one test set (93.7% versus 83.8%; p = 0.02), while obtains comparable recall rate on one test set and precision on the other two. At the image-level, CRCNet achieves an AUPRC of 0.990 (0.987-0.993), 0.991 (0.987-0.995), and 0.997 (0.995-0.999). Our study warrants further investigation of CRCNet by prospective clinical trials.

Abstract
COVID-19 has been prevalent in Wuhan and spread rapidly to all of our country. Some cases can develop into ARDS, or even death. We will share the treatment experience of severe COVID-19 with the first-line treatment experience. The best respiratory support mode should be selected, but the timing of intubation and protection during intubation are two difficulties; patients with high level peep and poor effect in prone position can be given ECMO support. For COVID-19 patients with mechanical ventilation, reasonable sedation and analgesia strategies should be formulated; delirium should not be ignored. In addition, there is up regulation of inflammatory factors in patients with severe COVID-19, but the effect of renal replacement therapy needs to be further confirmed by clinical research.

Abstract
The treatment of critically ill patients with coronavirus disease 2019(COVID-19) faces compelling challenges. In this issue, we'd like to share our first-line treatment experience in treating COVID-19. Hemodynamics need be closely monitored and different types of shock should be distinguished. Vasoconstrictor drugs should be used rationally and alerting of complications is of the same importance. The risk of venous thromboembolism (VTE) needs to be assessed, and effective prevention should be carried out for high-risk patients. It is necessary to consider the possibility of pulmonary thromboembolism (PTE) in patients with sudden onset of oxygenation deterioration, respiratory distress, reduced blood pressure. However, comprehensive analysis of disease state should be taken into the interpretation of abnormally elevated D-Dimer. Nutritional support is the basis of treatment. It's important to establish individual therapy regimens and to evaluate, monitor and adjust dynamically. Under the current epidemic situation, convalescent plasma can only be used empirically, indications need to be strictly screened, the blood transfusion process should be closely monitored and the curative effect should be dynamically evaluated.

Abstract
The new coronavirus pneumonia (NCP), also named as COVID-19 by WHO on Feb 11 2020, is now causing a severe public health emergency in China since. The number of diagnosed cases is more than 40,000 until the submission of this manuscript. Coronavirus has caused several epidemic situations world widely, but the present contagious disease caused by 2019 new coronavirus is unprecedentedly fulminating. The published cohorts of 2019 new coronavirus (n-Cov) are single-center studies, or retrospective studies. We here share the therapeutic experiences of NCP treatment with literature review. Combination of Ribavirin and interferon-α is recommended by the 5(th) edition National Health Commission's Regimen (Revised Edition) because of the effect on Middle East respiratory syndrome (MERS), and the effectiveness of Lopinavir/Ritonavir and Remdisivir needs to be confirmed by randomized controlled trial (RCT), given the situation of no specific antivirus drug on NCP is unavailable. Systemic glucocorticosteroid is recommended as a short term use (1~2 mg·kg(-1)·d(-1), 3~5 d) by the 5(th) edition National Health Commission's Regimen (Revised Edition) yet RCTs are expected to confirm the effectiveness. Inappropriate application of antibiotics should be avoided, especially the combination of broad-spectrum antibiotics, for the NCP is not often complicated with bacterial infection.

Abstract
Napsin A is widely used in the diagnosis of lung adenocarcinoma and has also been reported to be positive in cases of thyroid carcinomas. We investigated napsin A levels through immunohistochemistry on whole sections of 210 primary thyroid tumors of various subtypes and another 41 metastatic thyroid carcinomas, and compared these with 125 primary and 25 metastatic lung adenocarcinomas. The results showed that napsin A was expressed in 23.8% thyroid tumors and 30.3% papillary thyroid carcinomas. Most cases showed a focal and weak to moderate expression. In comparison, 80.8% primary lung adenocarcinomas expressed napsin A, with mostly diffused and strong expression. For metastatic carcinomas of thyroid and lung origin, napsin A was detected in 39.0% of thyroid carcinomas in contrast to 88.0% in cases of lung adenocarcinomas. Comparisons of additional markers, TTF-1, CK7, thyroglobulin, and Pax-8 in metastatic carcinomas showed the overlapping expression of immunomarkers of TTF-1 and CK7. Thyroglobulin and Pax-8 were useful for distinguishing between metastatic carcinomas; however, Pax-8 may be a superior marker due to its higher sensitivity. The clinicopathological analysis of papillary thyroid carcinomas showed that the expression of napsin A was positively correlated with lymph node metastasis (p = 0.030). Here, we focused on the expression of napsin A in thyroid tumors and compared it with that in lung adenocarcinomas. The expression of napsin A is common in thyroid tumors and the combined expression of napsin A and TTF-1 in a metastatic thyroid carcinoma is a cause for concern due to chances of misdiagnosis as lung adenocarcinoma.

Abstract
Vasculogenic mimicry (VM) is linked to vascular invasion of human hepatocellular carcinoma (HCC). BMP4, one BMP family member, is upregulated in several cancers. The purpose of this report is to identify the function of BMP4 in the formation of VM in HCC and the mechanism underling this regulation. In our report, BMP4 up-regulation resulted in an increase in migration, invasion and channel-like structure formation as well as induced epithelial-mesenchymal transition (EMT) process and stem cell-associated proteins OCT4 and SOX2 expression in HCC cells. In addition, The VM-associated proteins, including EphA2, VE-cadherin and MMP2, also could be effectively enhanced by the overexpression of BMP4. Furthermore, according to the TCGA database, higher expression of BMP4 is seen in HCC in contrast to normal liver samples. Immunohistochemistry revealed that BMP4 was positively associated with VM formation, age, histological differentiation, HCC stage, and shorter survival duration. These data demonstrated that BMP4 could promote VM network formation in HCC through induction of stemness in EMT and modulating the EphA2/VE-cadherin/MMP2 signaling pathway.

Abstract
Pulmonary sarcomatoid carcinomas (PSCs) are a rare subtype of non‑small‑cell lung cancer and are typically biphasic neoplasms. No effective treatment for PSCs is currently available in clinical practice. The expression of the epithelial‑mesenchymal transition (EMT) transcription factors, Twist1, Slug and Snail, as well as the EMT phenotype and vasculogenic mimicry (VM) were analysed in 41 PSC and 79 pulmonary squamous carcinoma (PSCC) samples. Compared with the PSCCs, the PSCs exhibited an EMT phenotype and VM, and they also exhibited an increased expression of the Twist1, Slug, Snail and VM markers. Twist1 expression was associated with metastasis and TNM stage. Twist1‑positive patients exhibited a poorer prognosis for overall survival (OS) than those with Twist1‑negative PSCs. Transforming growth factor β1 (TGFβ1) was used to induce an EMT transition in a PSCC cell line. SK‑MES‑1 cells treated with TGFβ1 exhibited an increased expression of Twist1. The EMT phenotype, VM and increased migratory and invasive abilities were induced following TGFβ1 treatment. Importantly, in cells treated with TGFβ1, the EMT phenotype was reversed, VM marker expression was decreased, and the migratory and invasive ability of the PSCC cell line was decreased following Twist1 knockdown. Collectively, this study provides a new perspective of Twist1 in the aggressiveness of PSCs. The identification of Twist1 as an independent marker of poor prognoses may lead to the development of novel strategies for improving the treatment of patients with PSC.

Abstract
Aromatase inhibitors (AIs) directly applies to postmenopausal breast cancer patients. Patients underwent bilateral ovariectomy or ≥60 years were acknowledged as postmenopausal.Alternatively, for <60 years breast cancer patients, sex hormone detection to evaluate menopause is recommended by National Comprehensive Cancer Network (NCCN) guideline, textbooks, and AIs clinical trials.However, series of clinical trial found that, a broad overlap region of follicle stimulating hormone and estradiol appeared between premenopausal and postmenopausal patients, which unable to determine the menopause even with sensitivity promotion of detection equipment or manners.We have abandon this detection in clinical treatment, and decision making was only according to the relapse risk and disease status. We recommend bilateral ovariectomy resection accompanied with AIs for breast cancer patients with high recurrence risk (e.g. T3-4 or LNM≥4) or patients with advanced metastatic disease.However, patients with low or moderate recurrence risk can be treated with tamoxifen.

Abstract
OBJECTIVE The aim of this study was to evaluate whether serum miR-661 could serve as a biomarker for the diagnosis and prognosis of non-small cell lung cancer (NSCLC). PATIENTS AND METHODS The expression of serum miR-661 was detected in 150 cases of NSCLC and 114 cases of normal healthy controls by Real-time PCR. Receiver-operating characteristic (ROC) curve analysis was applied to analyze diagnostic value of serum miR-661. The relationship between serum miR-661 expression and clinicopathological characteristics was investigated. Overall survival was analyzed using Kaplan-Meier method. Moreover, Cox proportional-hazards regression analyses were performed to determine the prognostic value of serum miR-661 in NSCLC patients. RESULTS We found that the expression of serum miR-661 was significantly upregulated in NSCLC compared with healthy controls (p < 0.01). The expression level of serum miR-661 was positively correlated with histological grade (p = 0.011), lymph node metastasis (p = 0.003), distant metastasis (p = 0.021) and clinical stage (p = 0.005). Then, ROC curve analysis showed that serum miR-661 has considerable diagnostic accuracy, with an area under the ROC curve (AUC) of 0.726 (p = 0.001). Moreover, NSCLC patients with serum miR-661 higher expression have shown significantly poorer overall survival than those with lower serum miR-661 expression (p = 0.004). Furthermore, multivariate analyses showed that serum miR-661 expression levels were an independent prognostic factor for survival in NSCLC patients. CONCLUSIONS Overall, these findings indicate that serum miR-661 may be a potential biomarker for the diagnosis and prognosis of NSCLC.

Abstract
OBJECTIVE Serum miRNAs are promising biomarkers for the diagnosis and prognostication of many diseases. Our present study aimed at assessing the usefulness of serum miR-770 expression as a diagnostic and prognostic tool for non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Quantitative Real-time PCR (qRT-PCR) was used to measure expression level of serum miR-770 in 196 NSCLC patients and 77 healthy controls. The associations of serum miR-770 expression with clinicopathologic variables were analyzed. Receiver operating characteristic analysis (ROC) was used to determine the value of serum miR-770 as a biomarker for diagnosis of NSCLC. Kaplan-Meier and Cox regression analyses were performed to examine the relationship between serum miR-770 expression and prognosis of NSCLC patients. RESULTS We found that serum miR-770 levels were significantly decreased in NSCLC patients compared to healthy controls (p < 0.01). Decreasing serum miR-770 expression was significantly correlated with poorer histological grade (p = 0.015), positive lymph node metastasis (p = 0.007), and advanced tumor stage (p = 0.002). Moreover, we found that the diagnostic value of serum miR-770 for NSCLC patients from healthy controls resulted in an AUC of 0.835 (95 % CI, 0.751-0.919) with a sensitivity of 68% and a specificity of 89%, based on a cut-off value of 5.723. Kaplan-Meier analysis showed that decreased serum miR-770 expression was associated with poor overall survival of NSCLC patients (p = 0.000). Multivariate analysis confirmed that serum miR-770 was an independent prognostic factor in patients with NSCLC. CONCLUSIONS Our findings suggested that serum miR-770 may represent a novel diagnostic, prognostic biomarker and a potential therapeutic target for NSCLC.

Abstract
Objective: To investigate the deposition rate of Artemisia pollen in different nasal cavity regions and its influence factors in residents of northwest China. Methods: Thirty healthy adults from northwest China were enrolled. The computational fluid dynamics (CFD) and discrete phase model (DPM) were used for numerical simulation of nasal structures. The pollen deposition fraction in each anatomical part was counted and the effects of pollen density and breathing rate on deposition were analyzed. SPSS 19.0 software was used for statistical analysis. Results: The hottest deposition parts of Artemisia pollen were nasal septum (30.70%±12.27%), vestibule (27.45%±8.21%), middle turbinate area (13.59%±8.98%) and nasopharynx (7.14%±5.90%). When the inspiratory flow rate increased to 30 L/min, the deposition rates of pollen in nasal vestibule and nasal septum were significantly higher than that at the rate of 15 L/min (43.20%±11.14% vs 27.45%±8.21%, 51.48%±9.77% vs 30.70%±12.27%, t value was -8.126,-5.264, respectively, all P<0.05), which indicated that with the increase of the inspiratory flow rate, the deposition hotspot moved forward. Compared with the wet Artemisia pollen, the deposition rate of the dry pollen in nasal vestibule and nasal septum decreased significantly (16.55%±4.33% vs 27.45%±8.21%, 7.09%±3.69% vs 30.70%±12.27%, t value was 8.669, 9.173, respectively, all P<0.05). The escape rate at outlet increased from 17.00%±9.57% to 43.48%±13.43% (t=-9.282, P<0.05). Conclusions: The deposition of Artemisia pollen in nasal cavity is highly concentrated. The inhalation velocity and the dry-wet degree of pollen are the main determinants of the deposition site.

Abstract
Pancreatic cancer is a highly malignant gastrointestinal tumor with high invasiveness, easy metastasis, and poor chemoresistance. Surgery is still the preferred treatment for resectable pancreatic cancer. At present, inflammatory scoring systems based on serological indicators in patients with resectable pancreatic cancer can be divided into two types: the inflammatory scoring system based on c-reactive protein albumin and the inflammatory scoring system based on peripheral blood cell count. However, the specific mechanism between these inflammatory markers and the prognostic value of resectable pancreatic cancer remains unclear. This article reviews the correlation between systemic inflammatory response indexes and prognosis of patients with resectable pancreatic cancer, so as to provide help for the comprehensive treatment of pancreatic cancer.

Abstract
AIMS Porcine circovirus type 2 (PCV2) can cause postweaning, multisystemic wasting syndrome in pigs, which leads to enormous losses in the swine industry worldwide. Here, a genetically engineered Lactococcus strain expressing the main protective antigen of PCV2, the Cap protein, was developed to act against PCV2 infection as an oral vaccine. METHODS AND RESULTS Expression of the Cap protein was confirmed via western blot, ELISA and fluorescence microscopy. Over 90% of the recombinant pAMJ399-Cap/MG1363 survived a simulated gastrointestinal transit. It also survived the murine intestinal tract for at least 11 days. Then, the safety and immunogenicity of pAMJ399-Cap/MG1363 in orally immunized mice was evaluated. The levels of the sIgA, IgG and cytokines (IL-4 and IFN-γ) obtained from the mice immunized with pAMJ399-Cap/MG1363 were significantly higher than those in the control groups. CONCLUSIONS pAMJ399-Cap/MG1363 can survive in the gastrointestinal transit and effectively induce mucosal, cellular and humoral immune response against PCV2 infection via oral administration. SIGNIFICANCE AND IMPACT OF THE STUDY This study demonstrates the potential of the genetically engineered Lactococcus lactis as a candidate for an oral vaccine against PCV2.

Abstract
OBJECTIVE This paper aims at screening the common differential genes of coronary atherosclerotic heart disease (CAD) and ischemic cardiomyopathy (ICM), and to conduct pathway analysis and protein-protein interaction (PPI) network analysis for the differential genes. MATERIALS AND METHODS The CAD and ICM datasets were collected from the Gene Expression Omnibus (GEO) database for human tumors to extract data components of peripheral blood RNA of patients and normal people in GSE71226 and GSE9128 chips; "limma" package of "R" software was used to screen the differential genes, and "pheatmap" package was applied to construct heat maps for the differential genes; Cytoscape, Database for Annotation, Visualization and Integration Discovery (DAVID) and String platforms were utilized for PPI network analysis, Genome Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis on the selected differential genes. RESULTS A total of 575 differential genes were screened from GSE71226, including 350 genes with up-regulated expression and 225 with down-regulated expression, which was statistically significant (p<0.05, fold change >1). 75 differential genes were screened from GSE9128, including 47 genes with up-regulated expression and 28 with down-regulated expression. By virtue of String, DAVID and Cytoscape software, the PPI network diagram was constructed, and GO and KEGG analyses were performed successfully. CONCLUSIONS A total of 8 common differential genes are screened, and functional annotation and pathway analysis are conducted, which is conducive to further studying the interactions between the differentially expressed genes.
