Abstract
Aspirin-exacerbated respiratory disease (AERD) is a clinical syndrome characterized by chronic rhinosinusitis with nasal polyps, asthma and the development of significant airway symptoms following the ingestion of aspirin and other nonsteroid anti-inflammatory drugs (NSAIDs). At present, aspirin challenge is the gold standard for diagnosis. Aspirin desensitization and aspirin therapy after desensitization (ATAD) is one of the classical therapies. This paper described the application of aspirin desensitization and ATAD in AERD and provided the reference for the comprehensive treatment of AERD.

Abstract
To predict early remission following anti-integrin therapy (vedolizumab [VDZ]) in patients with moderate-to-severe active ulcerative colitis (UC) using non-invasive biomarkers. The clinical data of a cohort of 33 patients with moderate-to-severe active UC admitted to the Department of Gastroenterology at Suzhou Municipal Hospital between January 2021 and December 2022 were collected. Of these, 9 patients declined VDZ treatment, and 21 received VDZ at doses of 300 mg weeks 0, 2, and 6, each administered within a 30-minute infusion period. The treatment regimen aimed to induce remission of clinical symptoms; hence, the same dose was administered every 8 weeks. At weeks 0 and 14, serum C-reactive protein (CRP) and erythrocyte sedimentation rate were measured using a modified Mayo score. In addition to clinical assessment, stool samples at baseline and weeks 14 were collected and evaluated using 16SrRNA gene sequencing and gas chromatography-mass spectrometry (GC-MS). Clinical remission was determined based on the clinical symptoms and partial Mayo scores. In patients who received VDZ, the strains of bifidobacterium longum (P = 0.022) and bacteroides sartorii (P = 0.039) significantly increased after treatment than before treatment. GC-MS analysis showed that taurine (P = 0.047) and putrescine (P = 0.035) significantly decreased after treatment. Furthermore, while acetamide exhibited a notable increase (P = 0.001), arachidic acid (P < 0.001) and behenic acid (P = 0.005) demonstrated statistically significant elevations. The combined prediction model of acetamide, taurine, and putrescine demonstrated a high predictive value of early remission in patients with moderate-to-severe active UC following VDZ treatment (area under the curve = 0.911, P = 0.014).

Abstract
Objective: To clarify the definition of severe pulmonary tuberculosis and its inclusion criteria by summarizing and analyzing the studies of severe pulmonary tuberculosis (TB). Methods: A systematic search of Medline (via PubMed), Cochrane Library, Web of Science, Web of Science, Epistemonikos, Embase, CNKI, WanFang database, and CBM database was conducted to collect studies published between 2017 and 2022 on patients with severe pulmonary TB. Searches were performed using a combination of subject terms and free words. The search terms included: tuberculosis, severe, serious, intensive care, critical care, respiratory failure, mechanical ventilation, hospitalization, respiratory distress syndrome, multiple organ failure, pulmonary heart disease, and pneumothorax. The definitions and inclusion criteria for severe pulmonary TB in the included studies were extracted. Results: A total of 19 981 studies were identified and 100 studies were finally included, involving 8 309 patients with severe pulmonary TB. A total of 8 (8.00%) studies explicitly mentioned the definition of severe pulmonary TB, and 53 (53.00%) studies clearly defined the inclusion criteria for patients with severe pulmonary TB. A total of 5 definitions and 30 inclusion criteria were extracted. A total of 132 dichotomous variables and 113 continuous variables were included in the outcome indicators related to patients with severe pulmonary TB of concern in the studies. Conclusions: The definition and diagnostic criteria for severe TB are unclear, and there is an urgent need to develop a clear definition and diagnostic criteria to guide clinical practice.

Abstract
Background High expression of CLDN6 in hepatocellular carcinoma (HCC) has been widely reported. During this research, CLDN6's effect on the infiltration, migration, and apoptosis of HCC cells was investigated. Methods Initially, the knockdown and overexpression of CLDN6 in HCC cells were carried out by short interfering RNA (siRNA) and plasmid transfection. The transfection efficiency was detected by means of a quantitative real-time polymerase chain reaction (qRT-PCR) assay, immunofluorescence staining, and Western blot analysis. Transwell and wound-healing assays were employed for the detection of invasion and migration ability. CCK-8 assay and flow cytometry were utilized for the detection of apoptosis. Finally, analysis of the expression of pathway-related proteins (JAK2, STAT3, p-JAK2, and p-STAT3) and the regulation of apoptotic responses (by measurement of cleaved caspase-3, Bax, and Bcl-2 levels) was carried out. Results When CLDN6 was knocked down, the cellular invasion and migration ability decreased, and apoptosis increased, which decreased p-JAK2, p-STAT3, and anti-apoptotic protein bcl-2 expression. Furthermore, an elevation was observed in cleaved caspase-3 and Bax expression levels. Contrarily, upon overexpression of CDLN6, the aforementioned experimental results were reversed. Conclusions CLDN6 knockdown results in the inhibition of HCC cells' infiltration and migration and promotes apoptosis via downregulation of the JAK2/STAT3 signaling pathway.

Abstract
Salmonella and pathogenic Escherichia coli are important foodborne pathogens. Phages are being recognized as potential antibacterial agents to control foodborne pathogens. In the current study, a polyvalent broad-spectrum phage, GSP044, was isolated from pig farm sewage. It can simultaneously lyse many different serotypes of Salmonella and E. coli, exhibiting a broad host range. Using S. Enteritidis SE006 as the host bacterium, phage GSP044 was further characterized. GSP044 has a short latent period (10 min), high stability at different temperatures and pH, and good tolerance to chloroform. Genome sequencing analysis revealed that GSP044 has a double-stranded DNA (dsDNA) genome consisting of 110,563 bp with G + C content of 39%, and phylogenetic analysis of the terminase large subunit confirmed that GSP044 belonged to the Demerecviridae family, Epseptimavirus genus. In addition, the genomic sequence did not contain any lysogenicity-related, virulence-related, or antibiotic resistance-related genes. Analysis of phage-targeted host receptors revealed that the outer membrane protein (OMP) BtuB was identified as a required receptor for phage infection of host bacteria. The initial application capability of phage GSP044 was assessed using S. Enteritidis SE006. Phage GSP044 could effectively reduce biofilm formation and degrade the mature biofilm in vitro. Moreover, GSP044 significantly decreased the viable counts of artificially contaminated S. Enteritidis in chicken feed and drinking water. In vivo tests, a mouse model of intestinal infection demonstrated that phage GSP044 was able to reduce the number of colonized S. Enteritidis in the intestine. These results suggest that phage GSP044 may be a promising candidate biologic agent for controlling Salmonella infections.

Abstract
BACKGROUND To investigate the effectiveness and safety of endoscopic variceal ligation and endoscopic tissue adhesive injection in the treatment of esophagogastric variceal bleeding. METHODS A total of 245 patients with EVB who attended the First Affiliated Hospital of Bengbu Medical College from December 2017 to June 2021 were retrospectively collected. The participants were divided into the esophageal EVL(E-EVL) + gastric EVL(G-EVL) group (n = 103) and E-EVL + gastric TAI(G-TAI) group (n = 142), according to the procedure, comparing and assessing the clinical characteristics, laboratory results, operation time, rebleeding rate, efficacy and complications. RESULTS The E-EVL+G-EVL group had significantly less varicose vein diameter and operative time than the E-EVL+G-TAI group (p < 0.05). No statistical difference in the length of hospital stay between the two groups was noted (p > 0.05). The total rebleeding rate in the E-EVL+G-EVL group was 9.7%, whereas that of the E-EVL+G-TAI group was 11.9%; no statistical difference between the two groups was noted (p > 0.05). The overall effective rate of the E-EVL+G-EVL group was 90.21%, whereas that of the E-EVL+G-TAI group was 92.81%; no statistical difference between the two groups was observed (p > 0.05). The postoperative ulcer in the E-EVL+G-EVL group was smaller and more superficial than that in the E-EVL+G-TAI group, the wound surface was smoother. CONCLUSION Both EVL and TAI have good therapeutic effects on EVB. Furthermore, owing to its effectiveness in preventing rebleeding, no reduction in efficacy and no increase in complications, shortened operative time, smaller and superficial ulcer and smoother wounds, gastric EVL is worthy of further clinical promotion.

Abstract
Objective: To observe the clinical efficacy, safety, compliance, and cost-effectiveness of rush immunotherapy (RIT) and conventional immunotherapy (CIT) in patients with allergic rhinitis (AR), so as to evaluate the clinical significance of CIT and preliminarily explore its economic value. Methods: A study was conducted on 72 AR patients who had received specific immunotherapy from Oct 2019 to Jun 2020 in the Department of Otorhinolaryngology, the First Affiliated Hospital of Chongqing Medical University, including 39 males and 33 females, aging 8 to 60 years. RIT or CIT was performed respectively according to the patients' wishes. There were 35 cases in the RIT group and 37 cases in the CIT group, all subjects were followed up for 1 year. Visual analysis scale (VAS) and effectiveness were used to evaluate the clinical efficacy. Systemic adverse reactions were used to assess safety. Failure rate was calculated to evaluate the compliance. The cost and cost-effectiveness ratio (CER) were conducted to evaluate the health economics preliminarily. Results: After half a year and one year's treatment, both RIT and CIT groups had significant clinical efficacy and RIT group had more significant clinical efficacy than CIT group at half a year (76.67% vs 46.67%, χ2=7.37, P=0.007). During the dose accumulation phase, there was no significant difference in the incidence of systemic adverse reactions between the two groups (8.57% vs 8.10%, χ2=0.05, P=0.943), while the drop-out rate in the RIT group was significantly lower than that in the CIT group (0 vs 13.51%, χ2=5.08, P=0.024). After one year, the costs in RIT group were significantly higher ((8 163.08±452.67) yuan vs (7 385.87±369.92) yuan, t=-2.78, P=0.009), while there was no statistical differences in CER between the two groups ((3 298.06±1 374.09) yuan/point vs (3 154.38±1 532.51) yuan/point, t=-0.36, P=0.418). Conclusions: Both RIT and CIT are beneficial for AR, and they have similar clinical efficacy, safety, and CER. RIT is more effective in the early stage, with higher patient compliance. Thus, RIT is worth promoting and exploring in clinic.

Abstract
We report pair distribution function studies on the relationship between the metal-insulator transition (MIT) and lattice distortions in pure and Ti-substituted bilayer Ca3Ru2O7. Structural refinements performed as a function of temperature, magnetic field and length scale reveal the presence of lattice distortions not only within but also orthogonal to the bilayers. Because of the distortions, the local and average crystal structure differ across a broad temperature region extending from room temperature to temperatures below the MIT. The coexistence of distinct lattice distortions is likely to be behind the marked structural flexibility of Ca3Ru2O7under external stimuli. This observation highlights the ubiquity of lattice distortions in an archetypal Mott system and calls for similar studies on other families of strongly correlated materials.

Abstract
PURPOSE Acromegaly caused by growth hormone cell adenoma is commonly associated with abnormal glucolipid metabolism, which may result from changes in adipocytokine secretion. This study aims to investigate serum adipokine levels, including pro-neurotensin (PNT), furin, and zinc alpha-2-glycoprotein (ZAG), in acromegalic patients and the correlation between the levels of these three adipokines and GH levels and glucolipid metabolism indices. METHODS Sixty-eight acromegalic patients and 121 controls were included, and their clinical data were recorded from electronic medical record system. Serum PNT, furin and ZAG levels were measured by ELISA. RESULTS Serum PNT levels in acromegalic patients were significantly higher than controls (66.60 ± 12.36 vs. 46.68 ± 20.54 pg/ml, P < 0.001), and acromegaly was an independent influencing factor of PNT levels (P < 0.001). Moreover, subjects with the highest tertile of PNT levels had a close correlation with acromegaly (OR = 22.200, 95% CI 7.156 ~ 68.875, P < 0.001), even in Model 1 adjusted for gender and age and Model 2 adjusted for gender, age and BMI. Additionally, serum PNT levels were positively correlated with BMI (r = 0.220, P = 0.002) and triglycerides (TGs, r = 0.295, P < 0.001), and TGs were an independent influencing factor of serum PNT levels in acromegalic subjects (P < 0.001). Furthermore, serum PNT levels in obese acromegalic patients were significantly higher than those with normal BMI (P < 0.05). However, serum furin levels were lower in acromegalic patients than controls (0.184 ± 0.036 vs. 0.204 ± 0.061 ng/ml, P < 0.001). CONCLUSION This study is the first to demonstrate that acromegalic patients have increased serum PNT levels. Moreover, serum PNT plays a potential role in abnormal lipid metabolism of acromegalic patients.

Abstract
Fluoride agents hold promise for the repair and prevention of caries lesions, but their interaction with enamel is often hampered and diminished because of the dynamic wet environment in the oral cavity, which affects the efficacy of fluoride delivery and limits treatment success. We herein developed a mussel-inspired wet adhesive fluoride system (denoted TS@NaF) fabricated by the self-assembly of tannic acid (TA), silk fibroin (SF), and sodium fluoride (NaF). TS@NaF demonstrated remarkable biological stability and biocompatibility, showed reliable wet adhesion, released fluoride ions (F−) topically, and induced significant deposition of calcium fluoride (CaF2) onto enamel in vitro. Furthermore, TS@NaF provided an anticaries effect in vitro and induced a detectable increase in enamel mineral density. Advanced fluoride-releasing bioadhesives are therefore promising candidates for caries prevention and highlight the great potential of mussel-inspired dental materials in clinical applications.

Abstract
PURPOSE Prolactinoma may reduce bone mineral density (BMD) and increase fracture risk, but its influence on bone microarchitecture remains to be elucidated. The purpose of this study is to evaluate bone microarchitecture parameters by high-resolution peripheral quantitative computed tomography (HR-pQCT) in prolactinoma patients. METHODS 31 prolactinoma patients and 62 age- and sex-matched healthy controls in our center were included, and HR-pQCT was used to evaluate their bone microarchitecture at the radius and tibia. Z-scores for bone microarchitecture parameters were calculated based on previously published reference. RESULTS After adjusting for height and weight, prolactinoma patients had lower trabecular (- 0.011 mm, p = 0.005) and cortical thickness (- 0.116 mm, p = 0.008) and cortical area (- 6.0 mm2, p = 0.013) at radius, as well as lower trabecular (- 0.014 mm, p = 0.008) and cortical (- 0.122 mm, p = 0.022) thickness at tibia compared with the controls. Patients with higher prolactin level had more severe bone microarchitecture impairments. After adjusting for prolactin level and age, male patients had lower trabecular volumetric BMD (vBMD), trabecular number, trabecular thickness, and cortical porosity at radius, as well as lower trabecular vBMD, trabecular bone volume fraction, trabecular number, and cortical area, and higher trabecular separation at tibia compared with female patients. Z-score for radius vBMD was correlated with Z-score for areal BMD (aBMD) at lumbar and femoral neck, while Z-score for tibia vBMD was correlated with Z-score for lumbar aBMD, and some patients with vBMD Z-score below - 2.0 had aBMD Z-score within normal range. CONCLUSION Peripheral bone microarchitecture was impaired in prolactinoma patients, especially in patients with higher prolactin level. We compared the bone microarchitecture of prolactinoma patients and healthy controls by high-resolution peripheral quantitative computed tomography (HR-pQCT), and found that many bone microarchitecture parameters were impaired among prolactinoma patients. Such impairment was more prominent among patients with higher prolactin level.

Abstract
Background It has been suggested that Helicobacter pylori (H. pylori) infection is associated with hypergastrinemia and proliferation of colorectal mucosa via direct stimulation, dysbiosis of the gut microbiome, and changes in the gut microbiome, all of which may lead to the formation of colorectal polyps. However, the consensus remains lacking regarding whether H. pylori infection is independently associated with colorectal polyps and whether the association differs according to histological type of colorectal polyps. To summarize the current evidence regarding the relationship between H. pylori infection and colorectal polyps, we conducted a meta-analysis of related observational studies according to the histological types of colorectal polyps. Methods Observational studies investigating the association between H. pylori infection and colorectal polyps using multivariate analyses were included by search of PubMed, Embase, and Web of Science. A random-effects model was adopted to combine the results. Results Seventeen studies that include 322,395 participants were analyzed. It was shown that H. pylori infection was independently associated with overall colorectal polyps (odds ratio [OR]: 1.67, 95% CI: 1.24–2.24, p < 0.001; I2 = 73%). According to the histological type of colorectal polyps, H. pylori infection was independently associated with adenomatous polyps (APs; OR: 1.71, 95% CI: 1.47–1.99, p < 0.001; I2 = 86%), advanced APs (OR: 2.06, 95% CI: 1.56–2.73, p < 0.001; I2 = 0%), and hyperplastic polyps (HPs; OR: 1.54, 95% CI: 1.02–2.30, p = 0.04; I2 = 78%). Evidence based on only one study showed that H. pylori infection was not associated with sessile serrated polyps (SSPs; OR: 1.00, 95% CI: 0.93–1.07, p = 0.99). Conclusions Current evidence from case-control and cross-sectional studies suggested that H. pylori infection was independently associated with colorectal APs, advanced APs, and HPs, but not with SSPs. These findings suggested H. pylori infection may be a possible risk factor of colorectal polyp, which is important for the prevention of colorectal polyp in the adult population.

Abstract
BACKGROUND Hereditary hemorrhagic telangiectasia is an autosomal dominant hereditary hemorrhagic disease. Its main feature is an abnormal structure of the blood vessel wall. Cirrhosis of the liver is a common chronic progressive disease with one or more causes in which diffuse liver damage occurs after long-term or repeated injury. Liver cirrhosis can cause dilation of gastrointestinal capillaries. Many patients with hereditary hemorrhagic telangiectasia accompanied by gastrointestinal vascular malformations and liver cirrhosis may be diagnosed only with liver cirrhosis if the clinician does not pay attention to physical examination findings and family history. Moreover, general treatment measures, such as blood transfusion, iron supplementation, and application of hemostatic drugs, are less effective for bleeding in patients with hereditary hemorrhagic telangiectasia than in those with liver cirrhosis alone. CASE PRESENTATION Here, we report the rare case of a 75-year-old Chinese man who was admitted to the hospital with repeated melena and epistaxis. He was diagnosed with unexplained liver cirrhosis, which was later confirmed as hereditary hemorrhagic telangiectasia. Subsequently, we implemented the treatment intervention of oral thalidomide combined with gastrointestinal argon plasma coagulation. A follow-up of more than 8 months showed that the treatment effect was excellent. CONCLUSIONS If patients with liver cirrhosis and gastrointestinal vascular malformations also have a family history of epistaxis, special attention should be paid to targeted physical examination results, and the possibility of hereditary hemorrhagic telangiectasia should be considered. Moreover, for patients with hereditary hemorrhagic telangiectasia and both gastrointestinal bleeding caused by gastrointestinal capillaries and repeated epistaxis, when other general treatment measures are ineffective, thalidomide combined with gastrointestinal argon plasma coagulation may be an effective intervention.

Objective: To explore the roles of aloperine in the chemosensitivity of the DDP-resistant colorectal cancer cell line HT-29 (HT-29/DDP) and the related mechanism. Results: Aloperine can inhibit the proliferation of both HT-29 and HT-29/DDP cells in a dose-dependent manner; moreover, aloperine can significantly increase the sensitivity of HT-29/DDP cells to DDP; finally, HIF-1α and p-ERK was upregulated in HT-29/DDP cells and transient over-expression of HIF-1α has blocked aloperine+DDP induced anti-proliferative and pro-apoptotic effects on HT-29/DDP cells. Conclusion: We are reporting for the first time that aloperine can increase the sensitivity of HT-29/DDP cells to DDP and reverse cisplatin resistance via downregulating the HIF-1α /ERK signaling pathway.

Abstract
RING finger protein 8 (RNF8) is an E3 ligase that is pivotal for DNA repair. However, the role of RNF8 in ulcerative colitis (UC) remains unclear. The aim of this study is to investigate the effect and the mechanism of RNF8 on UC model induced by trinitrobenzene sulfonic acid (TNBS) in mice. Lentiviruses overexpressing RNF8 were injected into mice after the induction of UC. The histopathological changes in colon tissues were assessed by haematoxylin and eosin staining. The mRNA level of RNF8 was detected by real-time quantitative polymerase chain reaction. The protein levels of RNF8, autophagy-related proteins (LC3 and P62) and AKT/mammalian target of rapamycin (mTOR) signalling-related proteins were measured by Western blot. The pro-inflammatory cytokines (tumour necrosis factor-α and interleukin-1β) were examined by immunohistochemical analysis. Immunoprecipitation was performed to analyse the interaction between RNF8 and AKT1. The TNBS-induced UC mice exhibited colonic damage and inflammation, accompanied by decreased RNF8 expression, impaired autophagy and increased phosphorylation levels of AKT and mTOR in the colon. However, these alterations were reversed by RNF8 overexpression. Furthermore, RNF8 bound to AKT1 and mediated its ubiquitination. Collectively, RNF8 overexpression protects against TNBS-induced UC, which might be due to its enhancement of autophagy by suppressing the AKT/mTOR signalling via AKT1 ubiquitination.

Abstract
BACKGROUND Glycolysis was an essential driver of chemo-resistance in colorectal cancer (CRC), albeit with limited molecular explanations. OBJECTIVE We strived to elucidate the involvement of lncRNA XIST/miR-137/PKM axis in chemo-tolerance and glycolysis of CRC. METHODS Altogether 212 pairs of tumor tissues and adjacent normal tissues were collected from CRC patients. Moreover, human CRC epithelial cell lines, including HT29, SW480, SW620 and LoVo, were purchased in advance, and their activity was estimated after transfection of si-XIST or miR-137 mimic. Furthermore, 5-FU/cisplatin-resistance of CRC cells was determined through MTT assay, and glycolytic potential of CRC cells was appraised based on oxygen consumption rate (OCR) and extracellular acidification rate (ECAR). RESULTS Highly-expressed XIST were predictive of severe symptoms and unfavorable 3-year survival of CRC patients (P< 0.05). Besides, silencing of XIST not only diminished proliferative, migratory and invasive power of CRC cells (P< 0.05), but also enhanced sensitivity of CRC cells responding to 5-FU/cisplatin (P< 0.05). Glycolytic potency of CRC cells was also undermined by si-XIST, with decreased maximal respiration and maximal glycolytic capacity in the si-XIST group as relative to NC group (P< 0.05). Nevertheless, miR-137 mimic attenuated the facilitating effect of pcDNA3.1-XIST on proliferation, migration, invasion, 5-FU/cisplatin-resistance and glycolysis of CRC cells (P< 0.05). Ultimately, ratio of PKM2 mRNA and PKM1 mRNA, despite being up-regulated by pcDNA3.1-XIST, was markedly lowered when miR-137 mimic was co-transfected (P< 0.05). CONCLUSIONS LncRNA XIST/miR-137 axis reinforced glycolysis and chemo-tolerance of CRC by elevating PKM2/PKM1 ratio, providing an alternative to boost chemo-therapeutic efficacy of CRC patients.

Abstract
Objective: To develop a fundus image quality assessment system based on computer vision technology and to verify its accuracy by comparing the results of artificial discrimination and using this system. Methods: The process of image evaluation was divided into four modules: fundus image preprocessing, fundus image quality evaluation, fundus image content detection and evaluation result output. The system was designed to automatically evaluate the image quality of each fundus image, identify the optic disc and macula, and judge whether the image was qualified or not according to the image quality discrimination rules. A total of 2 397 fundus images of 787 type 2 diabetes patients were selected as the test data set. The average age of the patients, including 384 males and 403 females, was (69.65±19.09) years old. The images were taken by the staff of community health service centers in Shanghai with a fundus camera. The fundus image quality assessment system was used to conduct quality control and classification of the data set. At the same time, 12 professional fundus picture readers were employed to conduct manual quality control and classification of this data set. The system quality control results and artificial quality discrimination results were compared and analyzed. Results: The fundus image quality assessment system automatically recognized left and right eyes and eye positions on the input fundus images. The quality control interface included four indicator lights, which respectively corresponded to the images with the optic disc or macula as the center of the left or right eye. Evaluation of each fundus image was completed within 1 second, and the results were automatically displayed on the user interface. The 2 397 fundus photos were identified manually as 1 846 qualified photos and 551 unqualified photos. Among the unqualified images, 62 (11.27%) were too dark, 51 (9.27%) were too bright, 59 (10.73%) were not clear in the macular area, 36 (6.54%) showed no macula or optic disc, 125 (22.73%) could not present the fundus structure, 175 (31.82%) were blurred, and 42 (7.64%) were blocked. The results of the system and manual assessment were consistent in 1 788 qualified images (96.86%) and 550 unqualified images (99.82%), with an overall consistency rate of 97.54%. Conclusion: The fundus image quality assessment system can achieve highly consistent results with the professional judgment of ophthalmologists and has the characteristics of objectivity.

Abstract
Objective: To explore whether the improvement of subjective symptoms and objective grades after endoscopic sinus surgery in patients with chronic sinusitis (CRS) are related to the degree of preoperative anxiety or depression and to provide reference for improving the effects of clinical treatment. Methods: The clinical data of one hundred and sixty patients with CRS treated by endoscopic sinus surgery in the First Affiliated Hospital of Chongqing Medical University from April 2018 to August 2019 were collected prospectively. The visual analogue scale (VAS) scores, self-rating anxiety scale (SAS) scores, self-rating depression scale (SDS) scores, Lund-Kennedy scores of nasal endoscopy and the Lund-Mackay scores of CT before and 6 months after surgery were used to analyse the correlation between the scores of anxiety or depression and the subjective and objective scores of patients before and after operation by grouping and layering. One hundred and one males (63.1%) and 59 females (36.9%) with an average age of 47.3 years (18-75 years) were included. Single-sample, independent or paired t-test, one-way ANOVA and rank-sum test were used for comparison and Pearson correlation analysis was used for the correlation between groups. Results: There was no statistical difference of anxiety or depression between different groups in terms of age, gender and course in the 160 effective patients (t values were -0.151, -0.487, -0.846, all P values>0.05; t values were -0.473, -1.302, -1.069, all P values>0.05). And the degree of preoperative anxiety or depression was positively correlated with the subjective scores, including overall discomfort, nasal obstruction, runny nose and olfactory decline (r values were 0.515, 0.606, 0.424, 0.306, all P values<0.01; r values were: 0.518, 0.584, 0.448, 0.308, all P values<0.01), but not significantly correlated with objective scores of Lund-Mackay and Lund-Kennedy (all P value>0.05). Moreover, as far as the symptoms of overall discomfort, nasal obstruction, headache and runny nose, the results of one-way ANOVA showed that the improvement of symptoms in patients with serious anxiety or depression was worse than that of the normal, mild and moderate patients (all P values<0.05). However, there was no significant difference in the scores of Lund-Kennedy 6 months after surgery between them (both P values>0.05). Conclusion: The state of anxiety or depression affects the improvement of symptoms after endoscopic sinus surgery for CRS patients. Compared with the patients with normal and mild to moderate anxiety or depression, the improvement of symptoms in patients with severe anxiety and depression is worse. It is necessary to evaluate the anxiety or depression of the patients with CRS who are going to undergo endoscopic sinus surgery.

Ischemic coronary artery disease (CAD) is a major public health problem across the world. Early detection and appropriate management significantly reduced CAD-induced morbidities and death. Endothelial cells are pathogenically implicated.
Purpose
Our study was designed to investigate the role of the soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) in the in vitro protective effect of Metoprolol against hypoxia-induced injury of Human umbilical vein endothelial cells (HUVECs). Secondly, the clinical significance of variations in serum levels of sLOX-1 in patients with CAD was assessed.
Methods
In vitro, hypoxic injury model of HUVECs was established in an atmosphere of 1% O2, 95% N2, and 5% CO2 for 24 hours. The protective effect and mechanism of action of the cardio-selective beta-blocker Metoprolol at 10–6 μM concentration was investigated.
Consented stable atherosclerotic CAD (n=150) and unstable angina pectoris patients (n=75) along with 150 healthy volunteer subjects were voluntarily enrolled in this ethically approved study. Invasive coronary angiogram with ≥50% stenosis at least in one major coronary artery was used for diagnosis. ESC/ACC/AHC/practical protocols were used for categorizing patients into stable or unstable CAD. Serum sLOX-1 level was measured using specific ELISA kit. The diagnostic significance of serum sLOX-1 levels was assessed by analyzing its area under the curve (AUC).
Results
In vitro hypoxic conditions induced high rate of cellular apoptosis, high levels of LOX-1 expression, reactive oxygen species (ROS) generation and LDH release from HUVECs after 24 hours incubation, compared to normoxic control cells. Metoprolol significantly decreased LOX-1 levels, and prevented the release of LDH and generation of ROS. This culminated into marked improvement in cellular viability of hypoxia-exposed HUVECs (p<0.001).
Compared to healthy subjects, serum levels of sLOX-1s were significantly elevated in atherosclerotic stable and unstable CAD patients (p<0.001). Serum sLOX-1 levels were increased by 4.21 folds in stable CAD patients and by 6.373 folds in atherosclerotic unstable angina patients vs. healthy participants. Moreover, the levels in the two patients' groups were significantly different (p<0.001). In stable angina CAD patients, sLOX-1 AUC = 0.929; and in unstable CAD patients, AUC = 0.944, indicating that serum sLOX-1 levels clearly differentiated patients from healthy participants with high specificity and sensitivity.
Conclusions
Extrapolated from HUVECs hypoxia-induced injury model and the protective effect of Metoprolol, elevation of the circulating levels of sLOX-1 correlated with increased risks for atherosclerotic CAD and is a highly sensitive and specific biomarker for early detection of the disease.

Abstract
BACKGROUND Considering the boosting effect of glycolysis on tumor chemoresistance, this investigation aimed at exploring whether miR-488/PFKFB3 axis might reduce drug resistance of colorectal cancer (CRC) by affecting glycolysis, proliferation, migration, and invasion of CRC cells. METHOD Totally, 288 CRC patients were divided into metastasis/recurrence group (n = 107) and non-metastasis/recurrence group (n = 181) according to their prognosis about 1 year after the chemotherapy, and their 3-year overall survival was also tracked. Besides, miR-488 expression was determined in peripheral blood of CRC patients and also in CRC cell lines (ie, W620, HT-29, Lovo, and HCT116). The targeted relationship between miR-488 and PFKFB3 was predicted by Targetscan software and confirmed by dual-luciferase reporter gene assay. Moreover, glycolysis and drug tolerance of CRC cells lines were assessed. RESULTS MiR-488 expression was significantly decreased in metastatic/recurrent CRC patients than those without metastasis/recurrence (P < .05), and lowly expressed miR-488 was suggestive of unfavorable 3-year survival, large tumor size, poor differentiation, in-depth infiltration, and advanced Duke stage of CRC patients (P < .05). Besides, CRC cell lines transfected by miR-488 mimic demonstrated decreases in glucose uptake and lactate secretion, increases in oxaliplatin/5-Fu-sensistivity, as well as diminished capability of proliferating, invading, and migratory (P < .05), which were reversible by extra transfection of pcDNA3.1-PFKFB3 (ie, miR-488 mimic + pcDNA3.1-PFKFB3 group). Finally, the mRNA level of PFKFB3 was down-regulated by miR-488 mimic in CRC cell lines after being targeted by it (P < .05). CONCLUSION The miR-488/PFKFB3 axis might clinically refine chemotherapeutic efficacy of CRC, given its modifying glycolysis and metastasis of CRC cells.

Abstract
Objective: To explore the subjective and objective evaluation methods in functional rhinoplasty. Methods: Sixty-four patients who underwent rhinoplasty in the Department of Otorhinolaryngology, the First Affiliated Hospital of Chongqing Medical University were included in this study from January 2017 to October 2018. There were 32 males and 32 females, with the age ranging from 18 to 45 years old. Before and 6 months after operation, nasal ventilation function was evaluated by Visual Analogue Scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE), nasal acoustic reflex and nasal resistance. Satisfaction with nasal appearance was evaluated by VAS, Rhinoplasty Outcome Evaluation (ROE) and facial proportions evaluation. Psychological state was assessed by Emotional Balance Scale and Rosenberg Self-esteem Scale. Finally, the Pearson correlation analysis of patient satisfaction was performed. SPSS 23.0 software was used for statistical analysis. Results: Compared with pre-operation, nasal obstruction VAS, NOSE scores, total nasal resistance and difference ratio of nasal resistance showed significantly decline after surgery (1.62±0.85 vs 7.56±1.44, 22.62±3.54 vs 69.75±7.85, (0.16±0.08) Pa·s/ml vs (0.31±0.43) Pa·s/ml, 0.33±0.28 vs 0.71±0.32, all P<0.05). VAS of appearance and ROE scores showed an increase after surgery (11.20±3.66 vs 2.70±0.97, 17.80±2.71 vs 7.50±1.12, all P<0.05). The measurement of the external nasal subunits showed that the length of the dorsum of the nose, the angle of the face to the nose, the angle of the frontal and the angle of the alar of the nose were obviously reduced ((29.33±4.26) mm vs (33.61±5.24) mm, (135.11±3.81)° vs (139.91±6.30)°, (130.63±2.88)° vs (136.74±5.72)°, (99.71±4.02)° vs (106.27±5.60)°, all P<0.05). The scores of postoperative Emotional Balance Scale and Rosenberg Self-esteem Scale increased significantly (5.88±1.54 vs 4.31±1.85, 28.31±2.64 vs 22.13±2.77, all P<0.05). The Pearson correlation analysis showed that patients' satisfaction was positively correlated with subjective score of nasal ventilation (VAS, NOSE), subjective score of nasal appearance (VAS, ROE) and emotional balance scale, while negatively correlated with nasal resistance, and not correlated with the measurement of external nasal subunit. There was a significant positive correlation between the subjective score of nasal ventilation and the measurement of nasal resistance, but there was no significant correlation between the subjective score of nasal appearance and the measurement of external nasal subunit. Conclusion: The subjective and objective evaluation of nasal ventilation function, aesthetics of nasal appearance and psychological state can evaluate the effect of functional rhinoplasty effectively.

Abstract
In conventional quasi-one-dimensional antiferromagnets with quantum spins, magnetic excitations are carried by either magnons or spinons in different energy regimes: they do not coexist independently, nor could they interact with each other. In this Letter, by combining inelastic neutron scattering, quantum Monte Carlo simulations, and random phase approximation calculations, we report the discovery and discuss the physics of the coexistence of magnons and spinons and their interactions in Botallackite-Cu_{2}(OH)_{3}Br. This is a unique quantum antiferromagnet consisting of alternating ferromagnetic and antiferromagnetic spin-1/2 chains with weak interchain couplings. Our study presents a new paradigm where one can study the interaction between two different types of magnetic quasiparticles: magnons and spinons.

Abstract
With the stringent emission regulation taking effect, it is difficult for the conventional desulfurization technology in circulating fluidized bed (CFB) boilers to meet the requirements of ultralow SO2 emission. Therefore, in this paper, the application of natural ultrafine limestone, with a Sauter mean diameter of less than 20 μm, was tested by conducting bench-scale, pilot-scale, and commercial-scale experiments to realize highly efficient desulfurization in CFB furnaces. In the past, such small-size limestone was considered unsuitable for CFB boilers. However, as demonstrated by bench-scale results, the desulfurization performance was clearly superior to that of coarse limestone, especially at low SO2 concentrations. In a 3 MWth pilot-scale CFB boiler, the ultrafine limestone exhibited competent desulfurization efficiency to that of the coarse limestone but clearly less significant catalytic effects on NOx formation. As revealed by field tests in four commercial-scale CFB boilers, when high-efficiency cyclones were applied to CFB boilers, the mass inventory of ultrafine particles was significantly increased and the residence time would be extended accordingly; thus, the ultrafine limestone can be used to achieve high desulfurization efficiency and even ultralow SO2 emission with a favorable Ca/S ratio. Furthermore, a technical roadmap was drawn for the cost-effective control of SO2 emission.

Abstract
Colorectal cancer (CRC) is a common human malignancy that accounts for 600,000 deaths annually worldwide. Chrysophanol, a naturally occurring anthraquinone compound, exhibits anti-neoplastic effects in various cancer cells. The aim of this study was to explore the biological effects of chrysophanol on CRC cells, and determine the underlying mechanism. Chrysophanol inhibited proliferation of and promoted apoptosis in CRC cells by activating the intrinsic mitochondrial apoptotic pathway. In addition, chrysophanol also suppressed tumor growth in vivo and increased the percentage of apoptotic cells in tumor xenografts, without general toxicity. Proteomic iTRAQ analysis revealed decorin (DCN) as the major target of chrysophanol. DCN was upregulated in the tumor tissues following chrysophanol treatment, and ectopic DCN expression markedly augmented the pro-apoptotic effects of chrysophanol in CRC cells. In contrast, DCN knockdown significantly abrogated chrysophanol-induced apoptosis in CRC cells. Taken together, chrysophanol exerts anti-neoplastic effects in vitro and in vivo in CRC cells by modulating DCN, there by highlighting its therapeutic potential in CRC.

Abstract
BACKGROUND Endothelial dysfunction plays a key role in diabetic atherosclerosis. High glucose (HG) is considered a stimulator in the development of diabetic atherosclerosis. The endoplasmic reticulum (ER) stress response is involved in HG-induced vascular injury. Crocin has antioxidative and antiapoptotic properties. OBJECTIVE The current study was to evaluate whether crocin can protect human umbilical vein endothelial cells (HUVECs) from HG-induced injury and explored the associated mechanism. METHODS HUVECs were treated with 33 mmol/L glucose as the HG condition. The endothelial protective effects of crocin were evaluated by comparison with the control groups. RESULTS The exposure of HUVECs to HG for 24 h remarkably induced the ER stress response and a sequence of injuries, as demonstrated an increase in the apoptotic cell number, the reactive oxygen species level and inflammatory cytokine generation, as well as a decline in vascular endothelial growth factor A expression. These changes were markedly alleviated by pretreating the HUVECs with either crocin or 4-phenylbutyrate (ER stress inhibitor) before exposure to HG. CONCLUSION Crocin exerted antioxidative, antiapoptotic, anti-inflammatory and proangiogenic effects in the HG-induced HUVEC injury model, which were probably mediated by a favorable modification of ER stress that requires further investigation.

Abstract
MicroRNAs (miRs) are post-transcriptional regulators involved in the initiation and progression of many tumors. Recently, naturally occurring circular RNAs (circRNAs) have been described in eukaryotic cells:;they comprise a new class of gene regulators. Naturally occurring circular miR sponges, which induce miR loss-of-function, can prevent endogenous onco-miRs from binding to their cognate mRNA targets. These findings suggest that synthetic (artificial) circular RNAs could be constructed as therapeutic molecular sponges to suppress harmful onco-miRs. Using enzymatic ligation, we designed and constructed a circular RNA containing both miR-21 and miR-93 binding sites. The synthetic circular sponge was resistant to digestion with RNase R. Luciferase assays and functional experiments showed that the circular multi-miR sponge was more stable than its linear counterpart. Moreover, endogenous miR-21 and miR-93 were inhibited by the circular sponge. In addition, the synthetic sponge significantly suppressed cellular proliferation and migration while promoting apoptosis in esophageal carcinoma cells. Finally, in a murine xenograft model, the circular sponge significantly inhibited tumor growth in vivo. Taken together, these findings establish that the design and construction of efficient artificial miR sponges represent a novel strategy to achieve miR loss-of-function in molecular cancer therapeutics.

Abstract
We report the observation of electric-voltage induced insulator-metal phase transition in a ruthenate Mott insulator Ca3(Ru0.9Ti0.1)2O7. We show that the electric field effect dominates and leads to a sharp phase transition at measurement temperatures far below the Mott transition, whereas the thermal effect becomes more significant and broadens the phase transition as the measurement temperature approaches the insulator-metal transition. The electric field induced insulator-metal transition is presumably attributed to the avalanche breakdown of the correlated insulating state when driven out of equilibrium. This work highlights the strategy of using electric voltage to control the phase transition of this system in addition to other nonthermal parameters such as magnetic field and pressure reported previously.

Abstract
Background As a member of the zinc-finger E-box binding protein (ZEB) family, ZEB1 can modulate onset and progression of various tumors, but its regulatory effect or mechanism in GC has not been defined. Material/Methods GC tumor tissues and adjacent tissues were collected from GC patients across different TNM stages. Real-time PCR was used to measure ZEB1 expression to analyze its correlation with pathological features of tumors. Cultured GC cell lines SGC-7901 and MGC-803 were randomly assigned into control group, scramble group, and ZEB1 siRNA group. Real-time PCR was employed to analyze ZEB1 expression, and MTT approach was used to measure cell proliferation. Cell apoptosis was evaluated by flow cytometry. Wound healing assay was used to detect its effect on cell migration. Expression of E-cadherin and Vimentin involved in epithelial-to-mesenchymal transition (EMT) was measured by Western blot analysis, along with Wnt5a proteins. Results GC tissues had upregulation of ZEB1 (P<0.05 compared to adjacent tissues), whose expression level was correlated with differentiation grade, lymph node metastasis, and tumor pathological stage (P<0.05). Transfection of ZEB1 siRNA into SGC-7901 or MGC-803 cells can suppress ZEB1 expression, inhibit tumor cell proliferation, enhance apoptosis, and inhibit cell migration. Transfected GC cells had higher E-cadherin expression and decreased Vimentin expression or Wnt5a expression (P<0.05 compared to the control group). Conclusions ZEB1 expression is increased in GC tumor tissues and is associated with pathological features. The downregulation of ZEB1 can facilitate cell apoptosis via mediating Wnt5a, further suppressing GC cell proliferation and migration, and reducing EMT occurrence.

Abstract
Circular RNAs (circRNAs) are a new class of RNA involved in multiple human malignancies. However, limited information exists regarding the involvement of circRNAs in gastric carcinoma (GC). Therefore, we sought to identify novel circRNAs, their functions and mechanisms in gastric carcinogenesis. We analyzed next-generation RNA sequencing data from GC tissues and cell lines, identifying 75,201 candidate circRNAs. Among these, we focused on one novel circRNA, circNF1 , which was upregulated in GC tissues and cell lines. Loss- and gain-of-function studies demonstrated that circNF1 significantly promotes cell proliferation. Furthermore, luciferase reporter assays showed that circNF1 binds to miR-16, thereby derepressing its downstream target mRNAs, MAP7 and AKT3. Targeted silencing or overexpression of circNF1 had no effect on levels of its linear RNA counterpart, NF1. Taken together, these results suggest that circNF1 acts as a novel oncogenic circRNA in GC by functioning as a miR-16 sponge.

Abstract
Clinical data of 2 cases with Rosai-Dorfman disease(RDD) originating from nasal septal mucosa were reported retrospectively,and the pertinent literature was reviewed. Without specific clinical features,RDD in nasal cavity could be misdiagnosed easily. Pathology revealed different morphologies of cell proliferation with engulfed lymphocytes,plasma cells and neutrophils. Immunohistochemical staining showed S-100(+),CD68(+),CD1(-).RDD disease generally has a benign course and is self-limited. Its diagnosis depends mainly on biopsy.As for the treatment of this disease,the strategies are not systemic and standard. Surgical treatment is used to excise the mass in nasal cavity,glucocorticoids treatment after surgery is inconclusive. The long-term effect need to be further observed..

Abstract
Primary organoid cultures generated from patient biopsies comprise a novel improved platform for disease modeling, being genetically stable and closely recapitulating in vivo scenarios. Barrett esophagus (BE) is the major risk factor for esophageal adenocarcinoma. There has been a dearth of long-term in vitro expansion models of BE neoplastic transformation. We generated a long-term virus-free organoid expansion model of BE neoplasia from patient biopsies. Both wild-type and paired APC-knockout (APCKO) BE organoids genome-edited by CRISPR-Cas9 showed characteristic goblet cell differentiation. Autonomous Wnt activation was confirmed in APCKO organoids by overexpression of Wnt target genes and nuclear-translocated β-catenin expression after withdrawal of Wnt-3A and R-spondin-1. Wnt-activated organoids demonstrated histologic atypia, higher proliferative and replicative activity, reduced apoptosis, and prolonged culturability. Wnt-activated organoids also showed sustained protrusive migration ability accompanied by disrupted basement membrane reorganization and integrity. This CRISPR-Cas9 editing human-derived organoid model recapitulates the critical role of aberrant Wnt/β-catenin signaling activation in BE neoplastic transformation. This system can be used to study other 'driver' pathway alterations in BE-associated neoplasia, avoiding signaling noise present in immortalized or cancer-derived cell lines.

Abstract
Objective:To analyze the clinical characteristics of fungus ball sphenoid sinusitis(FBSS) and its differences from fungus ball maxillary sinusitis(FBMS). Method:A retrospective analysis was made for 50 patients with FBSS and 273 patients with FBMS in the corresponding period, which were confirmed by postoperative pathological diagnosis. And the related factors and clinical characteristics of them were analyzed. Result:FBSS were common disease in women around 50 years old. The left side FBSS was more common than the right side. About 40 percent of patients' disease course was less than half a year.FBSS had many presenting symptoms such as headache, nasal obstruction, nasal mucus with blood, smelly nasal secretions, eye ache bilges or nasion acheand tears spill. However, headache, eye ache bilges and tears spill were more common in FBSS compared with FBMS(P<0.05). The CT scan showed that there were calcification shadows in the diseased softtissue of sinus cavity.It could be accompanied by local bone thickening, sclerosis and coloboma. Only one case had a secondary surgery in 50 cases of FBSS. The surgery cure rate was as high as 98 percent. Conclusion:FBSS had various of clinical symptoms.Some presenting symptoms such as headache, eye ache bilges, and tears spill had relative specificity. CT diagnosis was more specific, and the endoscopic sphenoidotomy was the most effective treatment.

Abstract
We report the evolution of transport properties in exfoliated Fe1+y Te (y = 0.04) nanoflakes of various thickness. In contrast to the sharp semiconducting-to-metallic phase transition observed in both bulk and thicker flakes, this transition becomes broadened for flakes with an intermediate thickness followed by the appearance of a superconducting-like feature upon further cooling. With the thickness further decreased, the flakes exhibit insulating transport behavior with significantly enhanced positive magnetoresistance, which can be explained using a variable range hopping mechanism, suggesting the nature of a highly disordered 2D system.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-related death worldwide. In China, the situation is even worse as cancer incidence and mortality continue to increase rapidly. Although tremendous progress has been made toward HCC treatments, the benefits for liver cancer patients are still limited. Therefore, it is necessary to identify and develop novel therapeutic methods. Neuronally expressed developmentally downregulated 4 (NEDD4), an E3 ubiquitin ligase, plays a critical role in the development and progression of various types of human cancers. In our study, NEDD4 acts as an oncoprotein in both QGY7703 and SMMC7721 liver cancer cell lines. We found that depletion of NEDD4 by siRNA transfection led to inhibition of cell growth, invasion and migration, and promotion of apoptosis. In contrast, overexpression of NEDD4 via plasmid transfection resulted in facilitated cell proliferation, invasion and migration, and decreased apoptosis. Importantly, we observed that tumor suppressor LATS1, also a core component of Hippo pathway, was negatively regulated by NEDD4 in liver cancer cells. Our findings suggested that NEDD4 may be involved in the HCC progression via regulating LATS1 associated signaling pathway. Therefore, targeting NEDD4-LATS1 signaling could be a potential therapeutic option for HCC treatment.

Abstract
Sr4Ru3O10, the n = 3 member of the Ruddlesden-Popper type ruthenate Srn+1RunO3n+1, is known to exhibit a peculiar metamagnetic transition in an in-plane magnetic field. However, the nature of both the temperature- and field-dependent phase transitions remains as a topic of debate. Here, we have investigated the magnetic transitions of Sr4Ru3O10 via single-crystal neutron diffraction measurements. At zero field, we find that the system undergoes a ferromagnetic transition with both in-plane and out-of-plane magnetic components at Tc ≈ 100 K. Below T * = 50 K, the magnetic moments incline continuously toward the out-of-plane direction. At T = 1.5 K, where the spins are nearly aligned along the c axis, a spin reorientation occurs above a critical field Bc, giving rise to a spin component perpendicular to the plane defined by the field direction and the c axis. We suggest that both the temperature- and field-driven spin reorientations are associated with a change in the magnetocrystalline anisotropy, which is strongly coupled to the lattice degrees of freedom. This study elucidates the long-standing puzzles on the zero-field magnetic orders of Sr4Ru3O10 and provides new insights into the nature of the field-induced metamagnetic transition.

Abstract
Bilayer ruthenate Ca3(Ru1-x Fe x )2O7 (x = 0.05) exhibits an incommensurate magnetic soliton lattice driven by the Dzyaloshinskii-Moriya interaction. Here we report complex field-induced magnetic phase transitions and memory effect in this system via single-crystal neutron diffraction and magnetotransport measurements. We observe first-order incommensurate-to-commensurate magnetic transitions upon applying the magnetic field both along and perpendicular to the propagation axis of the incommensurate spin structure. Furthermore, we find that the metastable states formed upon decreasing the magnetic field depend on the temperature and the applied field orientation. We suggest that the observed field-induced metastability may be ascribable to the quenched kinetics at low temperature.
