Abstract
Background and study aims Gastric cancer (GC) is usually preceded by premalignant gastric lesions (GPLs) such as gastric intestinal metaplasia (GIM). Information on risk factors associated with neoplastic progression of GIM are scarce. This study aimed to identify predictors for progression of GIM in areas with low GC incidence. Patients and methods The Progression and Regression of Precancerous Gastric Lesions (PROREGAL) study includes patients with GPL. Patients underwent at least two upper endoscopies with random biopsy sampling. Progression of GIM means an increase in severity according to OLGIM (operative link on gastric intestinal metaplasia) during follow-up (FU). Family history and lifestyle factors were determined through questionnaires. Serum Helicobacter pylori infection, pepsinogens (PG), gastrin-17 and GC-associated single nucleotide polymorphisms (SNPs) were determined. Cox regression was performed for risk analysis and a chi-squared test for analysis of single nucleotide polymorphisms. Results Three hundred and eight patients (median age at inclusion 61 years, interquartile range (IQR: 17; male 48.4 %; median FU 48 months, IQR: 24) were included. During FU, 116 patients (37.7 %) showed progression of IM and six patients (1.9 %) developed high-grade dysplasia or GC. The minor allele (C) on TLR4 (rs11536889) was inversely associated with progression of GIM (OR 0.6; 95 %CI 0.4-1.0). Family history (HR 1.5; 95 %CI 0.9-2.4) and smoking (HR 1.6; 95 %CI 0.9-2.7) showed trends towards progression of GIM. Alcohol use, body mass index, history of H. pylori infection, and serological markers were not associated with progression. Conclusions Family history and smoking appear to be related to an increased risk of GIM progression in low GC incidence countries. TLR4 (rs11536889) showed a significant inverse association, suggesting that genetic information may play a role in GIM progression.

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

Abstract
INTRODUCTION Immune checkpoint inhibitors (ICIs) have become a frontier in the field of clinical technology for advanced non-small cell lung cancer (NSCLC). Currently, the predictive biomarker of ICIs mainly including the expression of PD-L1, TMB, TIICs, MMR and MSI-H. However, there are no official biomarkers to guide the treatment of ICIs and to determine the prognosis. Therefore, it is essential to explore a systematic nomogram to predict the prognosis of ICIs treatment in NSCLC METHODS: In this work, we obtained gene expression and clinical data of NSCLC patients from the TCGA database. Immune-related genes (IRGs) were downloaded from the ImmPort database. The detailed clinical annotation and response data of 240 advanced NSCLC patients who received ICIs treatment were obtained from the cBioPortal for Cancer Genomics. Kaplan-Meier survival analysis was used to perform survival analyses, and selected clinical variables to develop a novel nomogram. The prognostic significance of FGFR4 was validated by another cohort in cBioPortal for Cancer Genomics. RESULTS 3% of the NSCLC patients harbored FGFR4 mutations. The mutation of FGFR4 were confirmed to be associated with PD-L1, and TMB. Patients harbored FGFR4 mutations were found to have a better prolonged progression-free survival (PFS) to ICIs treatment (FGFR4: P = 0.0209). Here, we built and verified a novel nomogram to predict the prognosis of ICIs treatment for NSCLC patients. CONCLUSION Our results showed that FGFR4 could serve as novel biomarkers to predict the prognosis of ICIs treatment of advanced NSCLC. Our systematic prognostic nomogram showed a great potential to predict the prognosis of ICIs for advanced NSCLC patients.

Abstract
OBJECTIVE Papillary thyroid carcinoma (PTC) is one of the general thyroid malignancies. Recently, microRNAs (miRNAs) have identified as pivotal gene regulators in PTC tumorigenesis. The aim of this study was to investigate the role of miR-486 in PTC and its underlying mechanism. PATIENTS AND METHODS Fifty-six pairs of PTC tissue and matched normal tissue samples were collected from PTC patients who underwent surgery at our hospital from March 2015 to September 2017. Human thyroid epithelial cell line Nthy-ori3-1and PTC cell lines (BCPAP, K1, HTH83, and TPC-1) were cultured. The mRNA and protein expression level were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) and Western blot, respectively. Additionally, the proliferation and migration abilities were checked by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) method and transwell assay, respectively. Furthermore, dual-luciferase reporter assay was performed to confirm the combination of miR-486 and TENM1. Xenograft Model experiments were performed to assess the effects of miR-486 on tumor growth in vivo. RESULTS MiR-486 expression was significantly reduced in PTC, which was associated with the poorer clinicopathologic characteristics and overall survival (OS) of PTC patients. Moreover, miR-486 restoration in PTC cells was confirmed to markedly inhibit proliferation, invasion, and migration via the regulation of extracellular-signal-regulated kinase (ERK) and protein kinase B (Akt) signaling pathways and epithelial-mesenchymal transition (EMT). In the meantime, teneurin transmembrane protein 1 (TENM1) was identified as a direct functional target for miR-486 in PTC cells on the basis of bioinformatic analysis and luciferase reporter assays. Additionally, we also verified that miR-486 restoration could prominently repress the PTC growth in vivo. CONCLUSIONS MiR-486 exerted anti-tumor functions in PTC progression and served as promising biomarkers for the PTC treatment.

Abstract
Targeting T cell receptor β-chain constant region 1 (TRBC1) CAR-T could specifically kill TRBC1+ T-cell malignancies. However, over-expressed CARs on anti-TRBC1 CAR transduced TRBC1+ T cells (CAR-C1) bound to autologous TRBC1, masking TRBC1 from identification by other anti-TRBC1 CAR-T, and moreover only the remaining unoccupied CARs recognized TRBC1+ cells, considerably reducing therapeutic potency of CAR-C1. In addition, co-culture of anti-TRBC1 CAR-T and TRBC1+ cells could promote exhaustion and terminal differentiation of CAR-T. These findings provide a rationale for pre-depleting TRBC1+ T cells before anti-TRBC1 CAR-T manufacturing.

Abstract
Abstract
Background
Plaque erosion with subsequent coronary thrombosis is considered as an important cause of ST-segment elevation myocardial infarction (STEMI). Smoking is a major risk factor for acute coronary thrombosis. However, the relationship between current smoking status and plaque erosion has not been systematically investigated.
Purpose
The present study aimed to investigate predictors of plaque erosion in current smokers and non-current smokers with STEMI by using optical coherence tomography (OCT).
Methods
Between January 2015 to December 2017, a total of 1313 STEMI patients underwent pre-intervention OCT of culprit lesion were enrolled and divided into two groups based on current smoking status: current smoking group (n=713) and non-current smoking group (n=600). Using established criteria, quantitative and qualitative underlying plaque characteristics were assessed by OCT. Clinical, angiographic and OCT characteristics of all enrolled patients were recorded. Univariable and multivariable logistic regression analyses were used to identify predictors of plaque erosion in two groups.
Results
Plaque erosion were found in 30.9% (220/713) culprit lesions in current smoking group and 20.8% (125/600) of those in non-current smoking group detected by OCT. In multivariate regression analysis, the predictors that strongly related to plaque erosion in the current smoking group were nearby bifurcation (OR: 4.84; 95% CI:2.38–9.87; p<0.001); the minimum fiber cap thickness (FCT, OR:1.05; 95% CI:1.03–1.08; p<0.001); thin-cap fibroatheroma (TCFA, OR: 0.22; 95% CI: 0.07–0.67; p=0.007) and lipid core length (OR: 0.91; 95% CI: 0.84–0.97; p=0.007). The predictors in the non-current smoking group were nearby bifurcation (OR: 4.84; 95% CI: 2.38–9.87; p=0.006); the minimal FCT (OR: 1.09; 95% CI: 1.06–1.13; p<0.001); multi-vessel disease (MVD, OR: 0.43; 95% CI: 0.19–0.97; p=0.042) and dyslipidemia (OR: 0.34; 95% CI: 0.14–0.84; p=0.020).
Conclusions
Predictors of plaque erosion causing STEMI onset are different between current smokers and non-current smoker, with nearby bifurcation and thicker minimal FCT both predicting plaque erosion in two groups of patients.

Abstract
Abstract
Background
It has been reported that the lumen factors of the culprit lesions are related to Thrombolysis in Myocardial Infarction (TIMI) flow grade in ST-Segment–Elevation Myocardial Infarction (STEMI) patients, but the factors of reduced TIMI flow in plaque erosion have not been studied.
Methods
329 STEMI patients with plaque erosion who underwent pre-intervention optical coherence tomography after thrombectomy were included and divided into 2 groups according to preprocedural TIMI flow grade [TIMI 0–1 (n=219) and TIMI 2–3 (n=110)].
Results
The patients with older age (55.7±11.1yrs vs. 51.8±10.6yrs, P=0.003) and diabetes patients (18.3% vs. 8.2%, P=0.015) had poorer TIMI flow, and the patients with reduced TIMI flow grade have lower initial cTnI (1.2ng/mL vs. 2.1ng/mL, P=0.023). The lesion in the LAD had better blood flow than the lesion in RCA (P=0.003), and the patients in TIMI 0–1 grade had more lipid plaques (53.9% vs. 41.8%, P=0.039), more macrophage (59.8% vs. 41.8%, P=0.002), and more calcification (34.2% vs. 21.8%, P=0.020). There was no statistically significant difference in the descriptive indicators of lipid or lumen between the two groups. And In a multivariate logistic regression model, the independent correlation factors of reduced TIMI flow grade in erosion patients were age, diabetes mellitus, lesion vessel, and macrophage.
Conclusions
In STEMI patients with plaque erosion non-lumen factors greatly affect flow, which suggests that systemic treatment is as important as local treatment for plaque erosion.

Abstract
Abstract
Background
Plaque erosion is a frequent and important mechanism of acute coronary thrombosis only secondary to plaque rupture. Recent studies suggested plaque erosion with noncritical stenosis could be treated conservatively that distinct from those with critical stenosis. However, characteristics of plaque erosions with different coronary stenosis remain unknown.
Purpose
The present study aimed to investigate morphological features of plaque erosions with different coronary stenosis using optical coherence tomography (OCT).
Methods
Consecutive ST-segment elevated myocardial infarction (STEMI) patients with OCT images of culprit lesion between August 2014 and December 2017 were enrolled and 348 cases presented with plaque erosion identified by OCT. Based on the severity of lumen area stenosis [calculated by (1-minimal lumen area/reference lumen area) * 100%], all culprit plaque erosions were divided into three groups: Group A (area stenosis<50%, n=50, 14.4%); Group B (50%≤area stenosis<75%, n=146, 42.0%); Group C (area stenosis≥75%, n=152, 43.7%). Clinical characteristics, lesion features detected by coronary angiography and OCT were compared among three groups.
Results
Of all 348 STEMI patients with plaque erosions, patients in Group A were youngest (p=0.008) and had the lowest frequency of hypertension (p=0.029) as compared with those in Group B and C. Angiographic analysis showed 72.0% of plaque erosions in Group A located in LAD, while 67.8% in Group B and 53.9% in Group C (p=0.039). OCT findings (Figure 1-A) showed the prevalence of fibrous plaque was significantly highest in Group A than those in Group B and C (82.0% vs. 54.8% vs. 34.9%, p<0.001), whereas lipid rich plaque was most frequent in Group C (16.0% vs. 43.8% vs. 62.5%, p<0.001). The prevalence of macrophage (p<0.001), microvessel (p=0.009) and cholesterol crystals (p<0.001) increased gradually from plaque erosion with lumen area stenosis <50% to 50–75% to ≥75%. Notably, compared with Group B and C, nearby bifurcation was most common in Group A (72.0% vs. 67.1% vs. 55.3%, p=0.036). Multivariable regression analyses (Figure 1-B) showed fibrous plaque and nearby bifurcation were independently associated with plaque erosion with noncritical stenosis (area stenosis<75%).
Conclusion
56.3% plaque erosion in STEMI patients presented with noncritical stenosis, having distinct morphological features from erosion with critical stenosis. Fibrous plaque and nearby bifurcation were independently associated with the presence of noncritically stenotic plaque erosion, remaining a desire to tailor treatment therapy to individual patients.

Abstract
Abstract
Background
Previous studies have suggested that Microchannel (MC) is associated with plaque progression and vulnerability. Optical coherence tomography (OCT) could provide a chance to directly visualize plaque neovascularization in vivo.
Methods
1268 STEMI patients who underwent OCT examination of culprit lesion were included and divided into MC group (the culprit plaque with MC, n=560) and no-MC group (the culprit plaque without MC, n=708). MC was defined as a no-signal tubuloluminal structure on the cross-sectional optical coherence tomographic image. Clinical, angiography and other plaque morphological characteristics were compared between the two groups. Logistic regression analysis was used to identify independent predictors of MC in overall. In addition, the difference of predictors on MC was found in plaque rupture (PR) and plaque erosion (PE).
Results
Significant differences between MC group and no-MC group were found in the frequency of thin-cap fibroatheroma (74.6% vs 64.4%, p<0.001), lipid plaque (91.8% vs 82.9%, p<0.001), lipid core length (13.7±6.5mm vs 12.6±6.3mm, p=0.006) and the minimal lumen area (MLA, 1.95±0.98mm2 vs 2.10±1.58mm2, p=0.046). In MC group, the other vulnerable plaque morphological characteristics, such as macrophage (88.8% vs 75.1%, p<0.001), cholesterol crystal (39.6% vs 32.9%, p=0.013), spotty calcification (38.6% vs 29.5%, p<0.001) were more frequent. And compared with MLA the more locations of the culprit lesion in MC group was proximal (proximal, 47.3% vs 38.1%, at MLA, 38.2% vs 44.2%, distal, 14.5% vs 17.7%, p=0.004).The difference of Hemoglobin (Hb, 147.5±16.9g/L vs 144.1±18.2g/L, p<0.001), lipidemia (TC, 188.7±43.6mmol/L vs 180.8±40.0mmol/L, p<0.001, LDL-C, 121.5±37.4mmol/L vs 115.7±36.8mmol/L, p=0.005, and TC/HDL, 4.0±1.6 vs 3.8±1.0, p<0.001), and hypertension (50.7% vs 44.2%, p=0.021) between 2 groups was statistically significant. Multivariable logistic regression models showed 7 independent parameters associated with MC in culprit plaque of overall: hypertension, Hb, TC, MLA, lesion location (compared with MLA), lipid core length, macrophage, spotty calcification. In addition, Hb, TC and MLA were common predictors of MC in PR and PE, however, the predictive effect of MLA on MC was opposite in PR [OR (95% CI)=1.266 (1.095–1.463), p=0.001] and PE [OR (95% CI)=0.742 (0.597–0.922), p=0.007].
Conclusions
MC in culprit plaque is associated with more lipid (especially cholesterol), higher Hb, hypertension, lesion location (compared with MLA) and the other vulnerable plaque morphological characteristics. The predictors of MC were different in plaque rupture and plaque erosion.

Abstract
Abstract
Background
Chronic inflammatory infiltration is a common process for atherosclerosis development. However, autopsy studies reveal that incidence rate of inflammatory infiltrates are less abundant in plaque erosion compared with plaque rupture.
Purpose
Studies performed by optical coherence tomography (OCT) have allowed to establish the severity of plaque inflammation by assessing macrophage infiltration (MØI). In this study, we aimed at assessing the impaction of MØI in plaque erosion among patients with STEMI by using OCT.
Methods
A total of 1561 patients with ST-segment elevation myocardial infarctions (STEMI) who underwent OCT imaging were enrolled in this study. According to the exclusion criteria, 312 patients with STEMI exhibiting plaque erosion were classified as MØI or no MØI.
Results
163 (52.2%) patients had MØI at the site of plaque erosion, whereas 149 (47.8%) patients had no evidence of MØI and patients of MØI group were significantly older (P=0.015). The result of angiography showed the prevalence of multi-vessel disease appeared more frequency (P=0.021) and diameter stenosis% were higher (P=0.031) in MØI group. OCT results showed the minimum fibrous-cap thickness was thinner (P<0.001) and the maximum lipid arc was larger (P=0.005) in MØI group. Some patients underwent imaging follow-up at 1 year. There was no significant difference in the culprit plaque morphology progress among two groups (Figure 1A-1D).
Conclusions
This study demonstrated that plaque inflammation can increase culprit lesion severity and plaque vulnerability in patients with STEMI caused by plaque erosion.

Abstract
OBJECTIVE To investigate the correlation between the endothelial cell apoptosis and sirtuin-3 (SIRT3) gene expression in atherosclerosis (AS) rats. MATERIALS AND METHODS The AS model in rats was established through the high-fat diet. A total of 12 rats fed normally were enrolled as the control group, while 12 rats fed with high-fat diet were enrolled as the experimental group. After the experiment, the aortic tissues of rats were collected, and the relative area of the arterial plaque (total area of plaque/total area of the vessel) was measured via oil red O staining. The serum was collected to detect the levels of blood lipid, including total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). Moreover, the expression levels of SIRT3 and apoptotic genes were determined via Reverse Transcription-Polymerase Chain Reaction (RT-PCR), Western blotting and immunohistochemistry (IHC), respectively. The apoptosis was detected via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. RESULTS The area of aortic plaque in the experimental group [(36.15±9.52)%] was significantly larger than that in the control group [(11.62±3.25)%] (p<0.01). Compared with those in the control group, the serum TC, TG and LDL-C levels were significantly increased in the experimental group, while the HDL-C level was significantly decreased (p<0.05). Compared with those in the control group, the mRNA and protein expression levels of SIRT3 in the aorta of rats markedly declined in the experimental group (p<0.05), while Caspase-3 and Caspase-9 expressions were significantly increased (p<0.05), respectively. The results of TUNEL staining revealed that the apoptosis in the aorta of rats in the experimental group was remarkably higher than that in the control group (p<0.05). CONCLUSIONS The expression of SIRT3 is deleted in the aorta of AS rats and closely related to the apoptosis. SIRT3 may serve as a potential target for the treatment of AS.

Abstract
Objective: To investigate the effect of antipsychotic medicine risperidone on prepulse inhibition of the startle reflex (PPI) and P50 deficit in patients with first-episode and chronic. Methods: Thirty-eight patients with first-episode schizophrenia and 36 patients with chronic schizophrenia, both in acute stage, were enrolled in the study. All patients were treated with risperidone of different doses (2 to 6mg/d). All patients fulfilled the evaluation of PPI and P50 before treatment and 8 weeks after treatment. The psychotic symptoms were assessed with Positive and Negative Syndrome Scale (PANSS), and the therapeutic effects were evaluated with PANSS reduction rate. Results: (1) There was no significant difference in PPI and P50 parameters between the two groups before treatment (PPI ratio: first group 43%±29%, chronic group 42%±27%, P>0.05; P50 S2/S1 ratio: first group 83%±33%, chronic group 82%±24%, P>0.05). (2) There was no significant correlation between PPI and P50 inhibition parameters and disease course, psychotic episodes and psychiatric symptoms (PANSS total score, positive symptoms score, negative symptoms score and general psychopathology symptoms score) of schizophrenia (P>0.05). (3) Except the group main effect for S2 amplitude (F=5.75, P=0.019), there was no significant change for main effect and interaction of the other P50 and PPI inhibition ratio parameters after treatment (P50 S2/S1 ratio: first group before treatment 83%±33%, after treatment 85%±49%, P>0.05; chronic group before treatment 82%±44%, after treatment 84%±35%, P>0.05. PPI ratio: first group before treatment 43%±29%, after treatment 42%±27%; chronic group before treatment 42%±27%, after treatment 41%±28%,P>0.05). The effect of risperidone on P50 and PPI parameters was not related to the therapeutic effect. Conclusion: Deficit in sensory gating inhibition exists in both first-episode schizophrenia and chronic schizophrenia, and risperidone is not effective in treating the deficit in sensory gating (PPI and P50) inhibition of schizophrenia.

Abstract
Aim: To develop an oxidative phosphorylation (OXPHOS)-related gene signature of lung adenocarcinoma (LUAD). Materials & methods: We split The Cancer Genome Atlas LUAD cohort into a training set and a test set; we used the least absolute shrinkage and selection operator Cox method to structure the OXPHOS-related prognostic signature in the training set and verified in the test set and GSE30219 dataset. Meanwhile, the diagnostic model was constructed using the logistic Cox method. Results: The signature consisted of seven genes (LDHA, CFTR, HSPD1, SNHG3, MAP1LC3C, COX6B2, and TWIST1). LUAD patients were divided into high- and low-risk groups, demonstrating good diagnostic and prognostic capabilities. Conclusion: We developed the first-ever OXPHOS-related signature with both prognostic predictive power and diagnostic efficacy.

Abstract
Lung cancer is the leading cause of cancer‑associated mortality worldwide. Parthenolide (PTL), a natural product extracted from the plant Tanacetum parthenium, (a flowering plant in the daisy family, Asteraceae) has been reported to inhibit cancer cell growth, including that of human lung cancer. However, the underlying mechanisms by which PTL exerts its anticancer effect have remained to be fully elucidated. In the present study, Cell Counting Kit‑8 and colony formation assays were used to assess the effect of PTL to inhibit cell proliferation, a wound‑healing assay was performed to assess cell migration and western blot analysis and PCR were employed to reveal the molecular mechanisms by which PTL inhibits human lung carcinoma cell growth. The results indicated that PTL substantially inhibited cell proliferation and migration in two lung cancer cell lines A549 and H1299. Mechanistically, the phosphorylation of insulin‑like growth factor 1 receptor (IGF‑1R), Akt and forkhead box O3α (FoxO3α) was blocked by PTL. Furthermore, IGF‑1‑induced Akt [protein kinase B or (PKB)] and FoxO3α phosphorylation were also inhibited by PTL treatment. In addition, PTL significantly suppressed lung cancer growth in a subcutaneous xenograft mouse model. Taken together, the present in vivo and in vitro results indicate that PTL may suppress lung cancer growth through inhibiting IGF‑1R‑mediated PI3K/Akt/FoxO3α signaling, suggesting that PTL may be an attractive candidate for the treatment of lung cancer.
