Abstract
PURPOSE/OBJECTIVE(S) This study aims to assess the anti-tumor activity and safety of concurrent chemoradiotherapy plus PD-1 blockade in patients with locally advanced cervical cancer. MATERIALS/METHODS This is a single-arm, open-label, prospective phase II study. The key inclusion criteria were treatment-naive patients aged 18-75 years with stage II A2-IVA (FIGO 2018) locally advanced cervical cancer. All patients were treated with concurrent chemoradiotherapy including 2 cycle cisplatin (75mg/m2, for three days, every 3 weeks[Q3W]), nedaplatin or carboplatin can be selected for patients who can't tolerate cisplatin. After CCRT, patients achieving complete response (CR), partial responses(PR), stable disease(SD) received adjuvant chemotherapy (docetaxel 75 mg/m2 day 1+ cisplatin DDP 25 mg/m2 day 1-3, Q3W) for 2 cycle. PD-1 blockade Sintilimab and Tislelizumab was administered intravenously at 200 mg every 3 weeks up to 1 year or until disease progression, unacceptable toxicity, or withdrawal of consent. The primary endpoint was objective response rate (ORR) assessed by investigators per Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1. Secondary endpoints were the 12, 24-month overall survival (OS) rates, the 12, 24-month disease free survival (DFS) rates and safety. RESULTS From February 2020 to June 2022, a total of 15 patients was enrolled. Median age was 57 years (range, 36-74 years). Stage IIA1 was documented in 2 patients, stage IIA2 in two patients, stage IIIA in one patient, stage IIIC1 in eight patients, and stage IVA in two patients. And 66.7% (10/15) of patients had Metastatic lymph node. Four patients received adjuvant chemotherapy. The ORR was 100%, with 4 patients achieving CR and 11 PR. The 12 and 24-month OS rates are 93.3% and 84%, the 12 and 24-month DFS rates are 86% and 75.4%, respectively. Treatment-related adverse events (TRAEs) occurred in 86.7% (13/15) of patients. Grade 3 TRAEs are leukocyte (n = 1), thrombocytopenia (n = 1), hepatitis (n = 1), skin reaction (n = 1). No treatment-related deaths occurred. And IFN-γ was significantly elevated after radiotherapy (p = 0.0073). CONCLUSION Concurrent chemoradiotherapy plus PD-1 blockade showed promising antitumor activity and manageable toxicities in patients with locally advanced cervical cancer. Long-term outcomes are still pending to further evaluate their therapeutic effects. (ChiCTR2000032856).

Abstract
PURPOSE/OBJECTIVE(S) Chronic inflammation has been proposed to be associated with tumor development and progression. Dynamic changes in serum cytokines induced by feedback mechanisms from tumors make differentiation of cause and effect difficult. MATERIALS/METHODS In this study, a bidirectional summary-level Mendelian randomization (MR) analysis was performed to elucidate the causal correlation between inflammatory regulators with colon (CC) and rectum (RC) carcinomas. Summary-level data on inflammation-related genetic variations were extracted from a genome-wide association meta-analysis. Corresponding data for CC and RC were obtained from the FinnGen (CC: 1396 cases vs. 174,006 controls; RC: 1,078 cases vs. 174,006 controls) and UK Biobank (CC: 2,226 cases vs. 358,968 controls; RC: 1,170 cases vs. 360,024 controls) consortiums. Inverse-variance weighted MR was used as the primary method, and sensitivity analysis was performed to assess the MR assumptions. RESULTS After P value correction and meta-analysis, there was evidence of direct associations between macrophage migration inhibitory factor (MIF) and CC (95% confidence interval (CI):1.001-1.003; P = 8.77×10-4) and inverse correlations between Interleukin-17 (IL-17) and RC (95% CI: 0.997-0.999; P = 1.15×10-3). Conversely, interleukin-1 receptor antagonist (IL1ra) was downregulated in patients at a higher risk of RC (P = 0.006), and no reliable results revealed a causal association between other cytokines and CC and RC. CONCLUSION Thus, this MR study suggests that downregulated serum MIF and elevated serum IL-17 concentrations may reduce the risk of CC and RC, respectively. Therefore, MIF and IL-17 may serve as potential therapeutic targets, and further exploration of their underlying mechanisms is warranted.

Abstract
PURPOSE/OBJECTIVE(S) Chemoradiotherapy is a major modality for treatment of small cell lung cancer (SCLC). Naples prognosis score (NPS) is a novel prognostic biomarker-based immune and nutritional status and that can be used to evaluate prognosis. Our study aimed to investigate the prognostic role of NPS in unresectable SCLC patients. MATERIALS/METHODS Patients treated with chemoradiotherapy were retrospectively analyzed between June 2012 and August 2017. We divided patients into three groups depending on the NPS: group 0, n = 31; group 1, n = 100; and group 2, n = 48, and associations between clinical characteristics and NPS group were analyzed. Spearman correlation analyses were used to estimate the correlations among NPS parameters. The univariable and multivariable Cox analyses were used to evaluate the prognostic value of clinicopathological characteristics and laboratory indicators for overall survival (OS) and progression-free survival (PFS). RESULTS Data from 179 patients were analyzed. Treatment modality (P < 0.001) and serum CEA (P = 0.03) were significantly different among the NPS groups. The age, sex, smoking status, KPS, Karnofsky performance score (KPS), disease extent, and number of metastatic sites were not correlated with NPS (all P > 0.05). Spearman correlation analyses showed that neutrophil-to-lymphocyte ratio (NLR) had a significant correlation with lymphocyte-to-monocyte ratio (LMR) (r = -0.495, P < 0.001). KPS, disease extent, prophylactic cranial irradiation, treatment response and NPS Group were associated with OS. In addition, KPS, disease extent, prophylactic cranial irradiation, treatment response and NPS Group were associated with PFS. Multivariate analysis results showed that NPS was identified as an independent prognostic factor for OS (Group 1: hazard ratio [HR] = 2.704, 95% confidence interval [CI] = 1.403-5.210; P = 0.003; Group 2: HR = 5.154, 95% CI = 2.614-10.166; P < 0.001) and PFS (Group 1: HR = 2.018, 95% CI = 1.014-4.014; P = 0.045; Group 2: HR = 3.339, 95% CI = 1.650-6.756; P = 0.001). CONCLUSION NPS is related to clinical outcomes in patients with unresectable SCLC. NPS as an innovative scoring system, can improves prediction of survival in unresectable SCLC patients.

Abstract
Abstract
Background
Lipidome disturbance has long been recognized to occur after myocardial infarction (MI). Accumulation of excessive fatty acids induces production of reactive oxygen species and consequently deteriorates cardiac injury in MI. However, the spatial and temporal lipid profile in the heart following ischemic injury remains unknown.
Purpose
We aim to uncover the temporal-spatial lipidome profile of the heart following ischemia reperfusion (I/R) injury and identify circulating lipids released from injured myocardium that are potentially useful for diagnosis of ischemic heart disease.
Methods
C57/BL6 mice were subjected to 30 min myocardial ischemia followed by removal of the ligature to establish reperfusion injury. Porcine I/R injury was induced by 105 min myocardial ischemia followed by reperfusion. Human plasma was obtained from 143 post-MI patients. Myocardial lipid profiles were generated by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MALDI-MSI) in different regions (infarct, remote and peri-infarct) at different time points. Moreover, the lipids in the heart and plasma were analysed by LC-MS/MS.
Results
We observed a drastic alteration in the lipidome with distinct spatial-temporal features in the injured heart by both MALDI-MSI and LC-MS/MS. In the infarct heart tissue, as revealed by LC-MS/MS, we observed an elevation of glycerolipids that peaked at 3 hours after I/R, and a sustained elevation of phospholipids and sphingolipids up to 3 days. Similar alternations in lipid profile was observed but much weaker in the remote and peri-infarct heart tissue compared to the infarct tissue. Among those lipids, PC 32:0 detected by MALDI-MSI highly overlapped CD68 staining at a single-cell level, showing a strong correlation of PC 32:0 with macrophage infiltration in mouse hearts (R2=0.93, p<0.0001). A similar increase of PC 32:0 in the infarct area was also observed in porcine hearts following I/R injury. Surprisingly, plasma levels of PC 32:0 in the mice decreased after I/R injury. In humans, plasma levels of PC 32:0 in post-MI patients were lower than that in healthy individuals (p=0.03). Further analysis demonstrated that plasma levels of PC 32:0 determined within 72 hours after percutaneous coronary intervention were negatively correlated with the 6-month post-MI cardiac ejection fraction in patients (R2=0.08, p<0.001).
Conclusions
A temporal-spatial lipidome profile was established in heart injury by synergizing LC-MS/MS and mass spectrometry imaging. PC 32:0 levels are positively correlated with myocardial macrophage infiltration but negatively correlated with cardiac function in cardiac I/R injury. Our findings indicate that PC 32:0 is a potential biomarker for cardiac injury and the inflammatory status in the injured heart.

Abstract
Supplementing diets with active dry yeast (ADY, Saccharomyces cerevisiae) improves the carcass quality grade of beef cattle and the tenderness of beef. The relevant mechanisms have not been fully elucidated, but may be related to the effect of ADY on oxidative stress and the activity of matrix metalloproteinases (MMPs). To provide further insight into these mechanisms, this study evaluated the influence of ADY supplementation on growth performance, carcass traits, meat quality, concentrations of MMPs in serum (MMP-2, MMP-9 and MMP-13), oxidative stress indices and antioxidant capacity indices in beef cattle. Forty-six crossbred Simmental × Yanbian bulls (∼18 months of age, BW 436 ± 35 kg) participated in a 145-day finishing trial. ADY supplementation significantly improved marbling deposition, intramuscular fat content, and beef tenderness (P < 0.05); altered individual fatty acid proportions in the beef and increased saturated fatty acids while decreasing polyunsaturated fatty acids (P < 0.05); significantly decreased the abundance of reactive oxygen species in serum and meat; significantly increased the level of superoxide dismutase in meat (P < 0.05); tended to increase the level of catalase (P = 0.075) in serum and glutathione reductase (P = 0.066) in meat; and increased the secretion of MMPs. The improvement of beef tenderness following ADY supplementation of finishing bulls is related to the effects of ADY on the secretion of MMPs and the lowering of oxidative stress.

Abstract
Abstract
Background
Teaching hospitals are are usually larger and have a higher level of complexity. Admissions for atrial fibrillation are commonly encountered by residents and fellows and they carry a hight cost, morbidity and mortality.
Purpose
Our aim is to do a retrospective analysis of the National Impatient Sample (NIS) from 2016 to 2018 and determine the impact of the hospital teaching status and rural Vs urban location in the atrial fibrillation admission outcomes.
Methods
We combined the NIS from 2016–2018. A primary diagnosis of atrial fibrillation was identified identified. We stratified the admissions based on the hospital teaching status. We defined as primary outcomes the length of stay (LOS), in hospital mortality and total charges/cost per admission. The secondary outcomes were the rates acute kidney injury (AKI), acute blood loss anemia (ABLA) and embolic stroke (ES). We used the Charlson comorbidity index. We used univariate and multivariate linear regressions for the continuous outcomes and logistic regressions for the binary outcomes.
Results
We identified 981,739 admissions with a primary diagnosis of atrial fibrillation; 513,914 (47%) were female patients, the average age was 70.5 years. In the teaching hospitals, the LOS was 0.3 days longer [95% CI: 0.22–0.37]; p=0.000 and the total hospital charges were higher (8406.32 dollar more per admission [95% CI: 6510.89–10301.76]; p=0.000); there was no difference in mortality compared to the non-teaching institutions (OR 1.03 [95% CI: 0.87–1.21]; p=0.628). In teaching hospitals, the rates of AKI, ABLA and ES were higher (OR 1.2, 95% CI [1.12–1.27]; p=0.000), (OR 1.29, 95% CI [1.09–1.53]; p=0.003) and (OR 1.72, 95% CI [1.11–2.66]; p=0.014)respectively. In a subgroup analysis comparing urban teaching hospitals Vs urban non-teaching Vs rural non-teaching hospitals, we found that the primary outcomes were similar than the above but the results in the secondary outcomes were driven mainly by a marked difference between rural and urban institutions regardless of teaching status, which makes us think that there might be under diagnosis of atrial fibrillation related complications in lower complexity rural hospitals. The difference in costs per admission was not as high when comparing urban teaching with non-teaching hospitals (5103.96 dollar higher, 95% [CI: 3008.70–7199.23]; p=0.000).
Conclusion
Amongst admissions for atrial fibrillation, the total cost per admission was higher in teaching hospitals which was concordant with a longer LOS. Although our results show higher rates of AKI, ABLA and ES in teaching hospitals, this might be caused by underdiagnosis of such conditions in non-teaching rural institutions compared to large teaching hospital systems and these were not associated with an increase rate of mortality. There is need for more research to determine the factors impacting the higher costs of atrial fibrillation admissions amongst teaching institutions.

Abstract
Abstract
Background
Cardiac arrest is a condition associated with high mortality rate and can cause significant social-economical burden in United States. Our study aim is to analyze the basic demographic of patients admitted for cardiac arrest and the incidence of complications following cardiac arrest.
Methods
Using the National Inpatient Sample from 2016–2018, we identified all the hospital admissions with a primary diagnosis code at discharge for cardiac arrest during the study period. We identified the basic characteristics including age, gender, race and admitting hospital status. The set primary outcome was inpatient mortality, length of stay (LOS) and total costs of admission. The secondary outcomes were the incidence of acute kidney injury, acute blood loss anemia, acute embolism and thrombosis of deep veins of lower extremity (DVT), pulmonary embolism, non-traumatic intracranial hemorrhage, and thromboembolic stroke. Multivariable logistic regression model analysis was performed to address potential confounders. The Charlson Comorbidity Index (CCI) was used to adjust for the severity of each patient's co-morbidities.
Results
A total of 44,655 patients was admitted for cardiac arrest during the study period. Mean age was 64 years; 56% were men; 63% were white, 20.7% were black, 9.2% were latino, 2.8% were Asian or pacific Islander. The total in-hospital mortality was 73.5%. The average length of stay was 4.2 days and the average total costs of admission was 83,516 dollars. Among the seven demographic characteristics: age, gender, race, hospital size, hospital region, hospital teaching status, insurance type; only hospital teaching status and hospital size were found to significantly impact the mortality. Acute kidney injury was the most common complication in post-cardiac arrest patient (42%), followed by acute blood loss anemia (3.6%), pulmonary embolism (2.3%) and DVT (2.1%). Thromboembolic stroke (0.2%) and non-traumatic intracranial hemorrhage (0.1%) are less common. During subgroup analysis, acute kidney injury was also found out to be a predictive factor of increased mortality (OR 1.64, p<0.001).
Conclusion
Cardiac arrest remains one of the conditions with highest mortality rate. In our study, age, gender or race dit not impact on the outcome of cardiac arrest. Among all the complications from cardiac arrest, acute kidney injury was the most common one and was associated with higher mortality rate.

Abstract
The incidence of proximal gastric cancer has shown a rising trend in recent years. Surgery is still the main way to cure proximal gastric cancer. Total gastrectomy with D2 lymph node dissection was considered to be the standard procedure for proximal gastric cancer in the past several decades. However, in recent years, many studies have confirmed that proximal gastrectomy can preserve part of the stomach function and can result in a better quality of life of the patient than total gastrectomy. Therefore, proximal gastrectomy is increasingly used in patients with proximal gastric cancer. Unfortunately, there are some concerns after proximal gastrectomy with traditional esophagogastrostomy. For example, the incidence of reflux esophagitis in patients who underwent proximal gastrectomy with traditional esophagogastrostomy is significantly higher than those patients who underwent total gastrectomy. To solve those problems, various functional digestive tract reconstruction methods after proximal gastrectomy have been proposed gradually. In order to provide some help for clinical treatment, in this article, we reviewed relevant literature and new clinical developments to compare various kinds of functional digestive tract reconstruction methods after proximal gastrectomy mainly from perioperative outcomes, postoperative quality of life and survival outcomes aspects. After comparison and discussion, we drew the conclusion that various functional reconstruction methods have their own advantages and disadvantages; large scale high-level clinical studies are needed to choose an ideal reconstruction method in the future. Besides, in clinical practice, surgeons should consider the condition of the patient for individualized selection of the most appropriate reconstruction method.

Abstract
Objective: To study the correlation between systemic inflammation level and emphysema degree and bone mineral density in chronic obstructive pulmonary disease (COPD) patients and its possible mechanism. Methods: 90 patients with stable COPD who met the inclusion criteria and 50 controls in the physical examination center during the same period were recruited. All the enrolled objects have collected general clinical data, analyzed peripheral blood samples, measuring the Low-attenuation area of lung and CT value of lumbar 1 vertebra (L1-CT) by chest spiral CT. According to LAA%, COPD patients were divided into 36 cases of the non-emphysema group, 32cases of mild to moderate emphysema group, and 22 cases of severe emphysema group. The correlation between L1-CT value, LAA%, peripheral blood inflammatory factors, and pulmonary function indices in each group was analyzed and compared. Results: The HU value of L1-CT (107±32) in the COPD group was significantly lower than that in the control group (153±30), and the difference was statistically significant (P<0.05). The higher the LAA% in COPD patients was, the lower the value of L1-CT was, and the difference between groups was statistically significant. Compared with COPD patients in the non-emphysema group, peripheral blood neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and C-reactive protein (CRP) were all increased in the emphysema group, and the differences were statistically significant (P<0.05). L1-CT was negatively correlated with LAA, PLR, NLR, and CRP while uncorrelated with serum concentration of calcium and phosphorus. Conclusion: The decrease in bone density in COPD patients is closely related to the degree of emphysema. It is associated with increased levels of systemic inflammation caused by COPD itself. Early and timely broad-spectrum anti-inflammatory treatment may have certain clinical significance for the prevention and treatment of comorbidity with osteoporosis.

Abstract
Background Currently, the surgical approach to adenocarcinomas of esophago-gastric junction (AEG) remains controversial. Function-preserving gastric surgeries are becoming more popular, with proximal gastrectomy with double-tract anastomosis being one of the most important for AEG. Meanwhile, with the increasing use of laparoscopic techniques in the treatment of gastric cancer, the safety and effectiveness of laparoscopic-assisted proximal gastrectomy with double-tract anastomosis for Siewert type II-III AEG need to be further clarified. Methods Data of patients with Siewert type II/III AEG was collected at our center from October 2010 to December 2019 were retrospectively analyzed. 61 patients underwent open proximal gastrectomy with double-tract anastomosis (OPG-DT group) and 52 underwent laparoscopic-assisted proximal gastrectomy with double-tract anastomosis (LAPG-DT group). The clinical features, surgery, and short-term outcomes of patients in these 2 groups were collected to assess the safety and feasibility of LAPG-DT. Results A total of 113 patients were analyzed, there were 98 males and 15 females. No death during the operation. The differences in the number of lymph nodes, time to first flatus time to first eating, postoperative hospital stay, Additional analgesics were not statistically significant between two groups. Although the operative duration of LAPG-DT group was significantly longer than that of the OPG-DT group [(217±61) vs. (161±14) min, P=0.000), while less blood loss and less stress in LAPG-DT group. Early and late postoperative complications were similar between two groups. Conclusions Although laparoscopic-assisted proximal gastrectomy with double-tract anastomosis requires long operative time, it is associated with less bleeding and milder stress. Therefore, it is a safe and feasible surgical method.

Abstract
BACKGROUND Identifying valid biomarkers for patient selection impressively promotes the success of anti-PD-1 therapy. However, the unmet need for biomarkers in gastrointestinal (GI) cancers remains significant. We aimed to explore the predictive value of the circulating T-cell receptor (TCR) repertoire for clinical outcomes in GI cancers who received anti-PD-1 therapy. METHODS 137 pre- and 79 post-treated peripheral blood samples were included. The TCR repertoire was evaluated by sequencing of complementarity-determining region 3 (CDR3) in the TRB gene. The Shannon index was used to measure the diversity of the TCR repertoire, and Morisita's overlap index was used to determine TCR repertoire similarities between pre- and post-treated samples. RESULTS Among all enrolled patients, 76 received anti-PD-1 monotherapy and 61 received anti-PD-1 combination therapy. In the anti-PD-1 monotherapy cohort, patients with higher baseline TCR diversity exhibited a significantly higher disease control rate (77.8% vs. 47.2%; hazard ratio [HR] 3.92; 95% confidence interval [CI] 1.14-13.48; P = 0.030) and a longer progression-free survival (PFS) (median: 6.47 months vs. 2.77 months; HR 2.10; 95% CI 1.16-3.79; P = 0.014) and overall survival (OS) (median: NA vs. 8.97 months; HR 3.53; 95% CI 1.49-8.38; P = 0.004) than those with lower diversity. Moreover, patients with a higher TCR repertoire similarity still showed a superior PFS (4.43 months vs. 1.84 months; HR 13.98; 95% CI 4.37-44.68; P < 0.001) and OS (13.40 months vs. 6.12 months; HR 2.93; 95% CI 1.22-7.03; P = 0.016) even in the cohort with lower baseline diversity. However, neither biomarker showed predictive value in the anti-PD-1 combination therapy cohort. Interestingly, the combination of TCR diversity and PD-L1 expression can facilitate patient stratification in a pooled cohort. CONCLUSION The circulating TCR repertoire can serve as a predictor of clinical outcomes in anti-PD-1 therapy in GI cancers.

Abstract
BACKGROUND To investigate the safety and merits of laparoscopic proximal gastrectomy with double-tract reconstruction (LPG-DT) for Siewert type II and III adenocarcinoma of the esophagogastric junction (AEG). METHODS Retrospective analysis of the clinical data of 100 consecutive patients with Siewert II and III AEG treated at the Affiliated Tumor Hospital of Zhengzhou University from October 2010 to October 2019 was performed. Out of these patients, 69 underwent open proximal gastrectomy with double-tract reconstruction (OPG-DT), while 31 underwent LPG-DT. The clinicopathological characteristics, perioperative data, and short-term outcomes of the two groups were compared. A P value <0.05 was considered statistically significant. RESULTS Males accounted for 87% of all patients. Lymph nodes (LNs) count, time to first meal, postoperative length of stay, and postoperative complications were similar between the OPG-DT and LPG-DT group. flatus time was significantly shorter in the LPG-DT group (P<0.05), while the duration of operation was significantly shorter in the the OPG-DT group (P<0.001). Furthermore, the LPG-DT group has less blood loss, shorter flatus time, and lower postoperative-day-5 white blood cell (WBC) count and C-reactive protein (CRP) levels (P<0.05). CONCLUSIONS Although LPG-DT took longer to perform, its advantages of reduced blood loss and less surgical stress reflected on inflammatory markers supports an acceptable surgical option for Siewert II and III AEG.

Abstract
BACKGROUND Total gastrectomy and proximal gastrectomy (PG) are both surgical options for the treatment of Siewert type III adenocarcinoma of the esophagogastric junction (AEG). Currently there is no consensus on selecting which procedure to perform; in particular, there are few reports of long-term outcomes for patients with local advanced AEG. The aim of this study was to validate the usefulness of PG with double-tract reconstruction in Siewert type III AEG. METHODS The clinical data of patients with Siewert type III AEG underwent PG with double-tract reconstruction (PG-DT) or total gastrectomy with Roux-en-Y anastomosis (TG-RY) at our hospital between October 2010 and October 2018. According to the defined inclusion and exclusion criteria, 2,146 cases were enrolled in this study. A 1-to-1 propensity score matching (PSM) was performed to compare the short and long-term outcomes between the 2 groups. RESULTS The operation time was longer in the PG-DT group, and the proportion rates of complications and recovery time was similar in the 2 groups. The rates of maintaining bodyweight and free-fat mass index were significantly higher in patients who underwent PG-DT compared to those who underwent TG-RY. While complications, recovery time and survival are similar between two groups. CONCLUSIONS Regarding short-term outcomes, PG-DT seemed to be superior in terms of maintaining body weight and skeletal muscle compared to TG-RY, while both had similar complications. It was found that PG-DT enabled a potentially longer survival of pathological stage II and III Siewert type III AEG, although the finding was statistically insignificant. These results may help surgeons to determine the appropriate surgical approach and strategy for patients with early and locally advanced Siewert type III AEG.

Abstract
Objective: To explore how influenza A virus (IAV) regulates airway inflammation via activating Toll-like receptor 7(TLR7)/nuclear factor of κB (NF-κB) signaling pathway in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods: Primary bronchial epithelial cells were isolated and cultured from normal controls and COPD patients. Samples were divided into 6 groups according to different in vitro treatment, including normal epithelial cell group (A), normal cells+IAV group (B), COPD epithelial cell group (C), COPD cells+IAV group (D), normal cells+TLR7 small interference RNA (si-RNA) group (E), COPD cells+TLR7 siRNA group (F). Protein expressions of TLR7 and NF-κB were detected by Western blot after 24h co-culture with IAV and TLR7 siRNA. Interleukin-6 (IL-6) and tumor necrosis factor α (TNF α) were detected by enzyme-linked immunosorbent assay (ELISA). Results: (1) Compared with group A [0.350±0.075 and 0.470±0.034, (53.000±6.532)pg/ml and (17.000±1.625)pg/ml],TLR7, NF-κB protein expression and IL-6, TNF α levels were significantly increased in group B[0.950±0.075 and 1.090±0.078,(185.000±7.874)pg/ml and (32.000±0.838)pg/ml], group C[0.780±0.056 and 0.910±0.045,(138.000±5.100)pg/ml and 29.000±1.323)pg/ml) and group D[1.280±0.031 and 1.540±0.051,(432.000±5.734)pg/ml and (52.000±3.453)pg/ml] (all P<0.01). Compared with group C TLR7, NF-κB protein expression and IL-6, TNF α levels were significantly increased in group D (P<0.01). (2) Compared with the group A[0.530±0.023 and 0.800±0.046,(51.000±0.327)pg/ml and (14.000±0.314)pg/ml], TLR7, NF-κB protein expression and IL-6, TNF α levels were significantly decreased in the group E[0.350±0.047 and 0.510±0.067,(26.000±1.081)pg/ml and(8.000±0.526)pg/ml] (P<0.05). Compared with group C[1.080±0.078 and 1.280±0.034,(125.000±2.249)pg/ml and (28.000±1.010)pg/ml], TLR7, NF-κB protein expression and IL-6, TNF α levels decreased in the group F[0.880±0.056 and 1.040±0.029,(83.000±1.125)pg/ml and (21.000±0.429)pg/ml] (P<0.05). Conclusion: Influenza viruses activate TLR7/NF-κB signaling pathway to regulate airway inflammation storms in patients with acute exacerbation of COPD. New therapeutic targets of acute exacerbation COPD may be studied based on these inflammation responses to influenza viruses.

Abstract
Background Neoadjuvant chemotherapy (NAC) followed by surgery currently offers promise as a strategy for patients with locally advanced gastric cancer (GC). However, there is limited evidence to guide treatment for TRG 0 and 1 patients with locally advanced GC after R0 resection. This study set out to explore the optimal management for TRG 0 and 1 patients with locally advanced GC after R0 resection. Methods The retrospective data of 154 TRG 0 and 1 patients with locally advanced GC following R0 resection who were treated between January 2012 and December 2018 were collected and analyzed. The Kaplan-Meier method was used to estimate the survival rate. Multivariate analysis was performed using the Cox proportional hazards model. Results The median follow-up was 34.1 (range, 6.6–90.9) months. Six patients (3.9%) were lost during follow-up. Of the 27 patients who experienced relapse, 12 died, including 2 patients who died of non-neoplastic causes. The 5-year recurrence-free survival (RFS) and 5-year overall survival (OS) were 71.6% (95% CI: 68.5–79.6) and 82.9% (95% CI: 76.9–86.1) for the whole cohort, respectively. Univariate analysis revealed that patients with carcinoembryonic antigen (CEA) <5.0 ng/ml after NAC (77.7% vs. 20.1%, P<0.001), distal gastrectomy (91.7% vs. 67.5%, P=0.046) had higher 5-year RFS. Meanwhile, combined resection (55.6% vs. 73.1%, P=0.042), major complications (42.7% vs. 80.50%, P<0.001), and lymph node metastasis (ypN+) (52.0% vs. 83.7%, P<0.001) had lower 5-year RFS. The multivariate analysis showed that CEA level after NAC (HR =2.876, 95% CI: 1.051–7.872, P=0.040), major complications (HR =2.432, 95% CI: 1.062–5.567, P=0.035), and lymph node metastasis (ypN+) (HR =3.183, 95% CI: 1.242–8.161, P=0.016) were independent prognostic factors. Conclusions TRG 0 and 1 patients with local GC after R0 resection following NAC had a good prognosis, especially patients with CEA <5.0 ng/mL after NAC, and those without major complications or lymph node metastasis. Monotherapy or no chemotherapy may offer options for treating TRG 0 and 1 patients without adverse prognostic factors.

Abstract
Glycerol is used as a bovine semen osmotic cryoprotectant that greatly improves the quality of frozen and thawed bovine sperm. However, high glycerol concentrations can have a toxic effect on frozen and thawed bovine sperm. Therefore, this experiment investigated the effect of replacing a portion of the glycerol in a cryoprotectant solution with crocin on the sperm apoptosis, protamine deficiency and membrane lipid oxidation of frozen and thawed Yanbian yellow cattle sperm. The experiment included a control group (6% glycerol) and four treatment groups: I (3% glycerol), II (3% glycerol +0.5 mM crocin), III (3% glycerol + 1 mM crocin) and IV (3% glycerol + 2 mM crocin). Computer assisted semen analysis was used to detect sperm motility, Hoechst 33,342, propidium iodide, and JC-1 staining were used to analyse sperm viability and mitochondrial membrane potential, chromomycin A3 staining was used to detect protamine deficiency and DNA damage, flow cytometry was used for sperm membrane lipid disorder detection and analysis, and real-time quantitative RT-qPCR was used to detect the mRNA expression levels of protamine-related genes (PRM2, PRM3), sperm acrosome-associated genes (SPACA3), oxidative stress-related genes (ROMO1) and apoptosis-related genes (BCL2, BAX). Compared to the control group, replacing a portion of glycerol with 1 mM crocin significantly improved sperm motility, plasma membrane integrity, membrane lipid disorders (p < .05) and viability, mitochondrial membrane potential, protamine deficiency (p < .01). The expression level of PRM2, PRM3, SPACA3 and BCL2 significantly increased (p < .05), while the expression levels of ROMO1 and BAX significantly decreased (p < .05). Accordingly, the BCL2/BAX ratio significantly increased (p < .05). In summary, the substitution of a portion of glycerol with crocin in cryoprotective solution improved the quality of Yanbian yellow cattle sperm after freezing and thawing.

Abstract
BACKGROUND The traditional Billroth II and Roux-en-Y anastomosis after laparoscopic distal gastrectomy for gastric cancer are associated with bile reflux gastritis and roux stasis syndrome, respectively. The uncut Roux-en-Y gastrojejunostomy can decrease the incidence of these complications by blocking the entry of bile and pancreatic juice into the residual stomach and retaining the impulses originating from the duodenum. The purpose of the present study was to compare the short-term outcomes of uncut Roux-en-Y (URY) and Billroth II combined Braun (BB) anastomosis. METHODS In this prospective, multi-center, two-arm randomized controlled trial, 124 patients with advanced distal gastric cancer were randomized into two groups: URY (n = 62) and BB (n = 62) groups. RESULTS The mean gastric juice pH was significantly lower in the URY group compared with the BB group (3.94 ± 0.71 vs. 5.83 ± 0.91, P < 0.0001). The bile reflux gastritis at 3 months (P < 0.0001) and 6 months (P = 0.002) was significantly more frequent in the BB group. No recanalization occurred in the URY group, and no significant difference was found between the two groups in terms of mean operative time (P = 0.69), mean time to perform anastomosis (P = 0.86), mean estimated blood loss (P = 0.77), mean number of harvested lymph nodes (P = 0.90), time to first passage of flatus or defecation (P = 0.87), postoperative hospital stay (P = 0.83), and the incidence of postoperative complications (P = 0.70). CONCLUSIONS URY anastomosis is associated with a significantly lower incidence of bile reflux gastritis and roux stasis syndrome compared with BB anastomosis.

Abstract
Periodontitis is a chronic inflammation of the periodontium caused by the loss of homeostasis between subgingival biofilms and susceptible hosts. Bacterial invasion into the gingival tissue and persistent infection are major events that lead to chronic inflammation. The intratissue bacterial communities are as complex as the subgingival biofilms and can also form biofilm-like structures, which will serve as a reservoir for local and systemic infections. The epithelium forms physical, chemical, and immunological barriers against invading microbes. Nevertheless, many bacterial species can invade the gingival epithelium through transcellular and paracellular pathways. In addition, both genetic and environmental factors of the hosts can affect epithelial barrier functions and thus bacterial invasion of the gingiva. In this review, current evidence for the bacterial invasion of the gingival tissue in periodontitis has been summarized, and the microbial and host factors that determine bacterial invasion of the gingiva have been reviewed.

Abstract
The aims of this pilot study are to evaluate the feasibility, safety, and effectiveness of conducting an enhanced nutritional support pathway including extended preoperative nutritional support and one month home enteral nutrition (HEN) for patients who underwent enhanced recovery after esophagectomy. We implemented extended preoperative nutritional support and one month HEN after discharge for patients randomized into an enhanced nutrition group and implemented standard nutritional support for patients randomized into a conventional nutrition group. Except the nutritional support program, both group patients underwent the same standardized enhanced recovery after surgery programs of esophagectomy based on published guidelines. Patients were assessed at preoperative day, postoperative day 7 (POD7), and POD30 for perioperative outcomes and nutritional status. To facilitate the determination of an effect size for subsequent appropriately powered randomized clinical trials and assess the effectiveness, the primary outcome we chose was the weight change before and after esophagectomy. Other outcomes including body mass index (BMI), lean body mass (LBM), appendicular skeletal muscle mass index (ASMI), nutrition-related complications, and quality of life (QoL) were also analyzed. The intention-to-treat analysis of the 50 randomized patients showed that there was no significant difference in baseline characteristics. The weight (-2.03 ± 2.28 kg vs. -4.05 ± 3.13 kg, P = 0.012), BMI (-0.73 ± 0.79 kg/m2 vs. -1.48 ± 1.11 kg/m2, P = 0.008), and ASMI (-1.10 ± 0.37 kg/m2 vs. -1.60 ± 0.66 kg/m2, P = 0.010) loss of patients in the enhanced nutrition group were obviously decreased compared to the conventional nutrition group at POD30. In particular, LBM (48.90 ± 9.69 kg vs. 41.96 ± 9.37 kg, p = 0.031) and ASMI (7.56 ± 1.07 kg/m2 vs. 6.50 ± 0.97 kg/m2, P = 0.003) in the enhanced nutrition group were significantly higher compared to the conventional nutrition group at POD30, despite no significant change between pre- and postoperation. In addition, European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 scores revealed that enhanced nutritional support improved the QoL of patients in physical function (75.13 ± 9.72 vs. 68.33 ± 7.68, P = 0.009) and fatigue symptom (42.27 ± 9.93 vs. 49.07 ± 11.33, P = 0.028) compared to conventional nutritional support. This pilot study demonstrated that an enhanced nutritional support pathway including extended preoperative nutritional support and HEN was feasible, safe, and might be beneficial to patients who underwent enhanced recovery after esophagectomy. An appropriately powered trial is warranted to confirm the efficacy of this approach.

Abstract
An interlaboratory study was conducted to evaluate a method for the determination of 3 Aconitum alkaloids, viz., aconitine, mesaconitine, and hypaconitine, in raw botanical material and dietary supplements. The alkaloids were extracted with diethyl ether in the presence of ammonia. After cleanup by solid-phase extraction to remove matrix interferences, the alkaloids were determined by reversed-phase liquid chromatography (LC)/UV detection at 235 nm with confirmation by LC/tandem mass spectrometry (MS/MS). A total of 14 blind duplicates were successfully analyzed by 12 collaborators. For repeatability, the relative standard deviation (RSDr) values ranged from 1.9 to 16.7, and for reproducibility, the RSDR values ranged from 6.5 to 33. The HorRat values were all <2 with only one exception at 2.3. All collaborating laboratories had calibration curves with correlation coefficients of >0.998. In addition, 6 collaborators performed the confirmation and were able to verify the identities of the alkaloids by using LC/MS/MS.

Abstract
BACKGROUND Gastric cancer (GC) is one of the most common causes of cancer death. Hypoxia is an important property of the tumor microenvironment of GC. Increasing evidence demonstrates that tumor-associated macrophages are related to the metastasis of GC, while the precise mechanism of how hypoxic macrophages affect tumor progression is still not fully understood. AIMS To examine whether the mediators released from hypoxic macrophages contribute to the invasion and proliferation of GC cells. METHODS Cell Counting Kit-8 was utilized to determine the proliferation of SGC7901 and MKN45 cells. The invasion of SGC7901 and MKN45 cells was measured by transwell invasion assay. Expression of VEGF mRNA in THP-1-derived macrophages was determined by RT-PCR, and protein level of VEGF in the culture medium was detected by ELISA. RESULTS The proliferation and invasion of SGC7901 and MKN45 cells were dramatically increased after treatment with conditioned medium (CM) collected from THP-1-derived macrophages under hypoxia (H-CM), and the phosphorylation of Akt and p38 in SGC7901 and MKN45 cells was also up-regulated by H-CM stimulation. Notably, blockage of PI3K-Akt or p38 MAP kinase abolished the effects of H-CM on the proliferation and invasion of SGC7901 and MKN45 cells. Furthermore, VEGF was increased in macrophages after hypoxia and administration with nintedanib, an inhibitor of VEGFR, significantly decreases the phosphorylation of Akt and p38, as well as the proliferation and invasion of SGC7901 and MKN45 cells in response to H-CM. CONCLUSIONS Our findings suggest that hypoxia-injured macrophages contribute to the proliferation and invasion of GC cells through the release of mediators such as VEGF.

Abstract
The study aimed to determine the effects of methionine hydroxy analog chelate zinc on the tibia quality, mineral deposit, apparent retention of nutrients, and liver metallothionein (MT) expression level of aged laying hens. A total of 960 layers (Hy-Line Grey, 57 wk old) were randomly assigned into 4 groups, and each group had 8 replicates of 30 hens. During the first 2 wk, groups were fed a basal diet without extra zinc (Zn: 35.08 mg/kg). During the ensuing 14 wk, 4 levels of Zn (inorganic Zn: 80 mg/kg; organic Zn: 20, 40, 80 mg/kg) were added to the diet. The results indicated that both the Zn source and level did influence tibia strength and calcium (Ca) and Zn concentrations of tibia (P < 0.05), whereas there were no differences in the copper (Cu) and phosphorus (P) concentrations of the tibia and the tibia length (P > 0.05). Moreover, dietary supplementation with 40 or 80 mg/kg of organic Zn showed higher Zn and Ca concentrations in the tibia and higher tibia strength. The Cu concentration in the liver showed no difference among the 4 treatments, whereas the Zn concentration in the liver increased with the increasing Zn level. The apparent retention of P, iron (Fe), and manganese (Mn) was not affected by the Zn level or source (P > 0.05). However, the organic Zn group increased the apparent retention of Cu, Zn, Ca, crude protein (CP), and energy, and the group supplemented with 40 or 80 mg/kg of organic Zn obtained significant effects (P < 0.05). Moreover, dietary supplementation with 40 or 80 mg/kg organic Zn increased the MT mRNA expression of the liver at week 72, whereas 20 mg/kg of organic Zn decreased it (P < 0.05). In conclusion, this study suggested that an optimum dietary (40 mg/kg) organic Zn level plays a key role in promoting the apparent retention of minerals and nutrients, trace element deposit, and MT mRNA expression.

Abstract
Gastric cancer is the third most common cause of cancer-related deaths and is the fifth highest incidence of cancer worldwide, especially in Eastern Asia, Central and Eastern Europe, and South America. Currently, surgery is the only curative treatment for gastric cancer; however, digestive tract reconstruction after distal gastrectomy for gastric cancer is controversial due to the postoperative complications such as reflux gastritis. There is an increasing trend toward laparoscopic uncut Roux-en-Y (URY) for radical gastrectomy. However, evidence on the feasibility of this procedure in patients undergoing laparoscopic radical distal gastrectomy is still absent. Thus, a prospective randomized trial is warranted. This is a prospective, multicenter, two-arm randomized controlled trial in which 210 patients will be randomly assigned to two groups: laparoscopic URY (n=105) and laparoscopic Billroth II plus Braun anastomosis (n=105). Each participant must be pathologically diagnosed with gastric cancer and undergo laparoscopic radical gastrectomy at Xijing Hospital and other four hospitals. The laparoscopic URY procedure is based on the Billroth II gastrojejunostomy plus Braun anastomosis, and then blocked the jejunum input loop at the stump–jejunal anastomosis. The patients’ demographic and pathological characteristics will be recorded. The total and oral nutritional intake, general data, total serum protein, serum albumin, blood glucose, and temperature will be recorded before surgery and at the time of hospitalization. Postoperative adverse events will also be recorded, as well as at follow-up appointments at three months and six months after surgery. The rate of reflux gastritis will represent the primary endpoint, and other secondary endpoints, which are all recorded.

Abstract
AIM To explore the T2-mapping signal characteristics of the thigh muscles in patients with dermatomyositis/polymyositis (DM/PM) and to investigate the correlation between thigh muscle T2 values, clinical parameters, and serum creatinine kinase (CK). MATERIALS AND METHODS Forty-two patients with DM/PM proven by diagnostic criteria were enrolled in the study along with 13 healthy control subjects. Both T2-mapping and conventional magnetic resonance imaging (MRI) images were obtained in the thigh musculature of all subjects. The T2 values of thigh muscles were compared between the DM/PM patients and control groups. Thirty-one DM/PM patients were evaluated with manual muscle testing (MMT) and serum CK levels. A Spearman correlation coefficient model was used to correlate the mean T2 values and clinical assessments. The Kruskal-Wallis test and receiver operating characteristic (ROC) curves were also utilised. p-Values <0.05 reflected statistical significance. RESULTS The T2 value of all oedematous muscles was greater on average than that of the unaffected muscles of the DM/PM patients (p<0.05) and the muscles of healthy volunteers (p<0.05). The T2 value of unaffected muscles in DM/PM patients was also greater than that of the normal muscles in healthy volunteers (p<0.05). The area under the curves (AUCs) for T2 relaxation time values was 0.72 with respective sensitivity and specificity of 72.6% and 65.4%. The mean T2 relaxation time of the 31 patients group and the MMTs (p<0.05) was correlated without serum CK levels (p>0.05). CONCLUSION T2 mapping is not only quantitatively used for subclinical muscle involvement in DM/PM, but also be used to demonstrate severity of damaged muscles in DM/PM.

Abstract
Identifying the exact transmission route(s) of infectious diseases in indoor environments is a crucial step in developing effective intervention strategies. In this study, we proposed a comparative analysis approach and built a model to simulate outbreaks of 3 different in-flight infections in a similar cabin environment, that is, influenza A H1N1, severe acute respiratory syndrome (SARS) coronavirus (CoV), and norovirus. The simulation results seemed to suggest that the close contact route was probably the most significant route (contributes 70%, 95% confidence interval [CI]: 67%-72%) in the in-flight transmission of influenza A H1N1 transmission; as a result, passengers within 2 rows of the index case had a significantly higher infection risk than others in the outbreak (relative risk [RR]: 13.4, 95% CI: 1.5-121.2, P = .019). For SARS CoV, the airborne, close contact, and fomite routes contributed 21% (95% CI: 19%-23%), 29% (95% CI: 27%-31%), and 50% (95% CI: 48%-53%), respectively. For norovirus, the simulation results suggested that the fomite route played the dominant role (contributes 85%, 95% CI: 83%-87%) in most cases; as a result, passengers in aisle seats had a significantly higher infection risk than others (RR: 9.5, 95% CI: 1.2-77.4, P = .022). This work highlighted a method for using observed outbreak data to analyze the roles of different infection transmission routes.

Abstract
Periodontitis is caused by dysbiotic subgingival bacterial communities that may lead to increased bacterial invasion into gingival tissues. Although shifts in community structures associated with transition from health to periodontitis have been well characterized, the nature of bacteria present within the gingival tissue of periodontal lesions is not known. To characterize microbiota within tissues of periodontal lesions and compare them with plaque microbiota, gingival tissues and subgingival plaques were obtained from 7 patients with chronic periodontitis. A sequencing analysis of the 16S rRNA gene revealed that species richness and diversity were not significantly different between the 2 groups. However, intersubject variability of intratissue communities was smaller than that of plaque communities. In addition, when compared with the plaque communities, intratissue communities were characterized by decreased abundance of Firmicutes and increased abundance of Fusobacteria and Chloroflexi. In particular, Fusobacterium nucleatum and Porphyromonas gingivalis were highly enriched within the tissue, composing 15% to 40% of the total bacteria. Furthermore, biofilms, as visualized by alcian blue staining and atomic force microscopy, were observed within the tissue where the degradation of connective tissue fibers was prominent. In conclusion, very complex bacterial communities exist in the form of biofilms within the gingival tissue of periodontal lesions, which potentially serve as a reservoir for persistent infection. This novel finding may prompt new research on therapeutic strategies to treat periodontitis.

Abstract
Increased expression of YEATS domain containing 4 (YEATS4) has been reported to have a correlation with progression in many types of cancer. However, the mechanism by which it promotes the development of gastric cancer (GC) is rarely reported. This study aimed to investigate the effect of YEATS4 on cell proliferation and tumor progression. The mRNA and protein expressions of YEATS4 in GC tissues and cell lines were analyzed. BGC-823 cells then overexpressed or silenced YEATS4 by transfection of different plasmids. The regulatory effect of YEATS on cell viability, colony formation, cell apoptosis, and tumor growth in vivo was evaluated. Finally, we explored the underlying regulatory mechanism of YEATS4 on the Wnt/β-catenin pathway. YEATS4 was highly expressed in GC tissues and cell lines. Furthermore, Kaplan-Meier survival analysis and qRT-PCR analysis showed that the increased expression of YEATS4 indicated poor prognosis and tumor progression. The overexpression of YEATS4 significantly promoted cell proliferation and inhibited cell apoptosis, whereas the opposite trends were found upon the downregulation of YEATS4. Western blot analysis showed that the downregulation of YEATS4 inhibited protein expression and phosphorylation of β-catenin. In addition, decreased expressions of c-Myc, CDK6, CDK4, cyclin D1, and Bcl-2 and increased expression of Bax were observed in YEATS4 knockdown cells. Our results showed that increased expression of YEATS4 might play a critical role in promoting GC cell proliferation and apoptosis by activating the Wnt/β-catenin signaling pathway, indicating that the control of YEATS4 expression might be used as a promising therapy for GC.

Abstract
Acrylamide (ACR) is a chemical intermediate utilized in industry. ACR is also formed during heating of foods containing carbohydrates and amino acids. Therefore, humans are widely exposed to ACR, and ACR neurotoxicity in humans is a significant public health issue attracting wide attention. In this study, we investigated the potential neuroprotective effects of epigallocatechin-3-gallate (EGCG), the most abundant polyphenolic compound in green tea, in PC12 cells treated with ACR. ACR-treated PC12 cells pretreated with various concentrations of EGCG (2.5, 5 and 10 μM) for 24 h had increased viability and acetylcholinesterase activity and reduced apoptosis and necrosis compared to cells exposed to ACR alone. EGCG reduced the expression of bax mRNA, decreased cytochrome c release, reduced intracellular calcium levels, inactivated caspase 3 and increased mitochondrial membrane potential, suggesting that EGCG prevents ACR-induced apoptosis through a mitochondrial-mediated pathway. In addition, EGCG inhibited the formation of reactive oxygen species and lipid peroxidation while enhancing superoxide dismutase activity and glutathione levels, thereby reducing oxidative stress. Our results indicate that pretreatment of PC12 cells with EGCG attenuates ACR-induced apoptosis by reducing oxidative stress. Therefore, drinking green tea may reduce nerve injury induced by ACR.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF) is highly expressed in many types of tumors, including pancreatic cancer. Tumor cellderived VEGF promotes angiogenesis and tumor progression. However, the role of VEGF in glucose metabolism remains unclear. OBJECTIVE We investigated the role and the underlying mechanism of VEGF in the glucose metabolism of pancreatic cancer cells. METHOD Pancreatic cancer cells were stimulated with VEGF165 for 1 or 2 h. The oxygen consumption rates (OCR) and extracellular acidification rates (ECAR) were measured using the Seahorse XF96 Extracellular Flux Analyzer. Glycolytic enzymes were detected by quantitative real-time PCR. Neuropilin 1 (NRP1) was silenced by shRNA in order to investigate its role in VEGF-induced glycolysis. Immunohistochemistry (IHC) was performed to identify the correlation among VEGF, NRP1 and hypoxia inducible factor 1α (HIF1α) in pancreatic cancer tissues. RESULTS VEGF stimulation led to a metabolic transition from mitochondrial oxidative phosphorylation to glycolysis in pancreatic cancer. HIF1α and NRP1 protein levels were both increased after VEGF stimulation. The down-regulation of NRP1 reduced glycolysis in pancreatic cancer cells. NRP1 and VEGF levels both correlated with HIF1α expression in pancreatic tumor tissues. CONCLUSION VEGF enhances glycolysis in pancreatic cancer via HIF1α up-regulation. NRP1 plays a key role in VEGF-induced glycolysis.

Abstract
MicroRNAs (miRNAs) play a crucial role in the development and progression of human cancers, including gastric cancer (GC). The discovery of miRNAs may provide a new and powerful tool for studying the mechanism, diagnosis, and treatment of GC. In this study, we aimed to investigate the role of miR-326 in the development and progression of GC. Quantitative PCR (qPCR) was used to measure the expression level of miR-326 in GC tissues and cell lines. We found that miR-326 was significantly downregulated during GC. In addition, overexpression of miR-326 inhibited GC cell proliferation. Fluorescence-activated cell sorting (FACS) further showed that miR-326 significantly induced GC cell G2/M arrest. Subsequent dual-luciferase reporter assay identified one of the proto-oncogene NOB1 as a direct target of miR-326, and NOB1 can save growth inhibition caused by miR-326. We also confirmed that the growth inhibition caused by miR-326 is associated with AKT pathway activation. Taken together, our results indicate that miR-326 could serve as a potential diagnostic biomarker and therapeutic option for GC in the near future.

Abstract
Classical swine fever (CSF) is a devastating infectious disease of pigs caused by classical swine fever virus (CSFV). In China, CSF has been under control owing to extensive vaccination with the lapinized attenuated vaccine (C-strain) since 1950s, despite sporadic or endemic in many regions. However, recently, CSF outbreaks occurred in a large number of swine herds in China. Here, we isolated 15 CSFV strains from diverse C-strain-vaccinated pig farms in China and characterized the genetic variations and antigenicity of the new isolates. The new strains showed unique variations in the E2 protein and were clustered to the subgenotype 2.1d of CSFV recently emerging in China in the phylogenetic tree. Cross-neutralization test showed that the neutralizing titres of porcine anti-C-strain sera against the new isolates were substantially lower than those against both the highly virulent Shimen strain and the subgenotype 2.1b strains that were isolated in China in 2006 and 2009, respectively. In addition, experimental animal infection showed that the HLJZZ2014 strain-infected pigs displayed lower mortality and less severe clinical signs and pathological changes compared with the Shimen strain-infected pigs. The HLJZZ2014 strain was defined to be moderately virulent based on a previously established assessment system for CSFV virulence evaluation, and the virus shedding and the viral load in various tissues of the CSFV HLJZZ2014 strain-infected pigs were significantly lower than those of the Shimen strain-infected pigs. Taken together, the subgenotype 2.1d isolate of CSFV is a moderately virulent strain with molecular variations and antigenic alterations.

Abstract
Understanding the overall features of magnetic excitation is essential for clarifying the mechanism of Cooper pair formation in iron-based superconductors. In particular, clarifying the relationship between magnetism and superconductivity is a central challenge because magnetism may play a key role in their exotic superconductivity. BaFe2As2 is one of ideal systems for such investigation because its superconductivity can be induced in several ways, allowing a comparative examination. Here we report a study on the spin fluctuations of the hole-overdoped iron-based superconductors Ba1-xKxFe2As2 (x = 0.5 and 1.0; Tc = 36 K and 3.4 K, respectively) over the entire Brillouin zone using inelastic neutron scattering. We find that their spin spectra consist of spin wave and chimney-like dispersions. The chimney-like dispersion can be attributed to the itinerant character of magnetism. The band width of the spin wave-like dispersion is almost constant from the non-doped to optimum-doped region, which is followed by a large reduction in the overdoped region. This suggests that the superconductivity is suppressed by the reduction of magnetic exchange couplings, indicating a strong relationship between magnetism and superconductivity in iron-based superconductors.

Abstract
Dysregulation of microRNAs (miRNAs) are linked to tumorigenesis and tumor progression. In this study, we examined the expression of miR-489 in gastric cancer tissues and cells. Loss- and gain-of-function experiments were done to determine the roles of miR-489 in gastric cancer cell proliferation and invasion. Bioinformatic prediction, luciferase reporter assays, and Western blot analysis were employed to identify the target gene(s) of miR-489. We found that miR-489 was significantly (P < 0.05) downregulated in human gastric cancer tissues and cell lines, compared to their non-malignant counterparts. Enforced expression of miR-489 significantly suppressed gastric cancer cell proliferation and invasion, while miR-489 knockdown enhanced the aggressive behaviors of gastric cancer cells. Prospero homeobox 1 (PROX1) was identified to be a direct target of miR-489. A significant negative correlation was seen between miR-489 and PROX1 protein expression in gastric cancer tissues (r = -0.462, P = 0.023). Silencing of PROX1 phenocopied the suppressive effects of miR-489 in gastric cancer cells. Rescue experiments demonstrated that overexpression of a miR-489-resistant form of PROX1 significantly prevented the reduction in cell proliferation and invasion induced by miR-489 overexpression. In vivo studies confirmed that miR-489 overexpression retarded the growth of xenograft tumors, which was accompanied by reduced PROX1 expression. Overall, these data provide evidence for the suppressive activity of miR-489 in gastric cancer, which is ascribed to targeting of PROX1. The miR-489/PROX1 axis may represent a potential therapeutic target for this disease.
