Abstract
Discrepancy between coronary lesion severity and functional significance has always been a relevant issue in the management of patients undergoing coronary angiography and/or revascularization. We sought to investigate the relationship between quantitative flow ratio (QFR)-derived microcirculatory indices and anatomical-functional mismatch/reverse mismatch in intermediate coronary lesions. Intravascular ultrasound (IVUS) imaging and QFR were analyzed in 117 de novo intermediate coronary lesions. Lesions with QFR ≤ 0.8 were considered hemodynamically significant. Anatomical significance of the lesions was defined according to the best cutoff value of combined IVUS parameters for predicting QFR ≤ 0.8. QFR-derived microcirculatory indices including contrast-flow QFR minus fixed-flow QFR (cQFR-fQFR), hyperemic flow velocity and angiography-derived index of microcirculatory resistance (IMRangio) were calculated. The best cutoff values of IVUS parameters for predicting QFR ≤ 0.8 were minimum lumen area (MLA) 3.1mm2 and plaque burden (PB) 70%, with area under the curve of 0.635 and 0.703, respectively. The total discordance rate of lesion functional significance between IVUS and QFR assessments was 26.5%, with 21 lesions (17.9%) being classified as mismatch (MLA ≤ 3.1mm2 and PB ≥ 70% and QFR > 0.8) and 10 lesions (8.5%) as reverse-mismatch (MLA > 3.1 mm2 or PB < 70% and QFR ≤ 0.8). At multivariate analysis, IMRangio was identified as an independent predictor of mismatch (OR1.675, 95%CI:1.176-2.386, P = 0.004), whereas hyperemic flow velocity was identified as an independent predictor of reverse-mismatch (OR 1.233, 95%CI:1.073-1.416, P = 0.003). In intermediate coronary lesions, although MLA 3.1mm2 and PB 70% determined by IVUS are predictive of QFR-defined functional significance, the discordance rate remains substantial. QFR-derived microcirculatory indices are independently associated with anatomical-functional discordance between IVUS and QFR assessments.

Abstract
Gastric cancer (GC) is one of the major malignancies worldwide. Emerging evidence has revealed the potential involvement of long noncoding RNA (lncRNA) in human genetic disorders and cancer, but the role of LOC100505817 remains unknown. Thus, in this study, we isolated tissues from GC patients to characterize the functional importance of LOC100505817 in GC tumorigenesis. We also proposed a hypothesis that the regulation of Wnt/β-catenin pathway by LOC100505817 was regulated by miR-20a-mediated WT1. After the collection of cancer tissues and adjacent tissues were obtained from GC patients, expression of LOC100505817, Wnt/β-catenin pathway- and EMT-related genes was quantified. Ectopic expression and knockdown experiments were applied in order to investigate the protective role of LOC100505817 in the progression of GC. Subsequently, cell viability, flow cytometry for apoptosis and cell cycle were detected via CCK-8, while migration and invasion were determined using scratch test and Transwell assay respectively. Then interactions among LOC100505817, miR-20a and WT1 were explored by dual luciferase reporter gene assay, RNA pull down assay and RNA binding protein immunoprecipitation (RIP) assay. The results found poor expression LOC100505817 was poorly expressed in GC cells and tissues. Overexpressed LOC100505817 resulted in the significant reduction of cell proliferation, migration and invasion as well as the expression of Wnt2b, β-catenin, CyclinD1, N-cadherin, Vimentin and snail, while increased cell apoptosis along with the expression of E-cadherin. Wnt/β-catenin pathway and EMT in GC cells were suppressed by LOC100505817 through miR-20a-inhibted WT1. In summary, our results provided evidence suggesting that LOC100505817 inhibits GC through LOC100505817-mediated inhibition of Wnt/β-catenin pathway, that leads to the overall restraining of GC cell proliferation, migration and invasion through miR-20a-reduced WT1.

Abstract
We report the development of a high-resolution spectrometer for extended x-ray absorption fine structure (EXAFS) studies of materials under extreme conditions. A curved crystal and detector in the spectrometer are replaceable such that a single body is employed to perform EXAFS measurements at different x-ray energy intervals of interest. Two configurations have been implemented using toroidal crystals with Ge 311 reflection set to provide EXAFS at the Cu K-edge (energy range 8.9-9.8 keV) and Ge 400 reflection set to provide EXAFS at the Ta L3-edge (9.8-10.7 keV). Key performance characteristics of the spectrometer were found to be consistent with design parameters. The data generated at the National Ignition Facility have shown an ≃3 eV spectral resolution for the Cu K-edge configuration and ≃6 eV for the Ta L3-edge configuration.

Abstract
Upregulating the expression of long noncoding RNA LINC00982 controlled cell proliferation in gastric cancer, but the regulatory molecular mechanisms are yet to be expounded. We here aimed to elaborate how LINC00982 regulated the malignancy of gastric cancer cells. RT-qPCR and Western blot analysis were used to detect the expression of LINC00982 and cathepsin F (CTSF) in gastric cancer tissues and cells. Modulatory effect of LINC00982 on gastric cancer cells was assessed by CCK-8, colony formation, Transwell migration, and invasion assays. The relationship between LINC00982, YRPW motif 1 (HEY1), and CTSF was examined by RNA-binding protein immunoprecipitation, luciferase assay, and chromatin immunoprecipitation, and their interaction in the regulation of gastric cancer cellular functions was analyzed by performing gain-of-function and rescue assays. The nude mouse model of tumor formation was developed to examine the effects of LINC00982 on tumorigenesis. LINC00982 was lowly expressed in gastric cancer tissues, whereas its overexpression impaired the proliferative, migratory, and invasive properties of gastric cancer cells. Furthermore, LINC00982 could bind to transcription factor HEY1 and inhibited its expression. Through blocking the binding of HEY1 to CTSF promoter, LINC00982 promoted the expression of CTSF. Overexpression of HEY1 or inhibition of CTSF could reverse the antitumor effects of LINC00982 on gastric cancer, which were further demonstrated in vivo. All these taken together, LINC00982 acted as a tumor suppressor in gastric cancer, which is therefore suggested to be a potential antitumor target for gastric cancer.NEW & NOTEWORTHY We identified LINC00982 as a promising antitumor target for the treatment of patients with gastric cancer. We also determined a regulatory network involved in the pathophysiology of gastric cancer wherein LINC00982 could bind to HEY1 to impair its binding to cathepsin F (CTSF) promoter and hence promote CTSF expression, which aids in better understanding of molecular mechanisms related to gastric tumorigenesis.

Abstract
Objective: To investigate the correlation between serum ferritin (SF) level and liver damage in the acute stage of dengue fever. Methods: A retrospective study was conducted to analyze 171 cases diagnosed with dengue fever as dengue fever group and 130 healthy patients as control group in Hangzhou 3A grade hospital from July to December 2017. Clinical data, SF and liver function related indicators were collected from both groups: alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) to analyze the correlation between liver damage and SF in patients with dengue fever. Results: ALT, AST, and SF levels were significantly higher in the dengue fever group than those in the healthy control group (Z = 11.553, 15.054 and 15.163, P < 0.001). SF levels were higher in the dengue fever combined with liver damage group than those without the liver damage group (z = 6.930, P < 0.001). However, there was no statistically significant differences in age, gender, peak body temperature, and history of liver disease (P > 0.05). In addition, Spearman's correlation analysis showed that SF was positively correlated with ALT, AST, and TBIL (r = 0.464, 0.531 and 0.315, P < 0.001). Among dengue patients with different SF levels, there were significant difference in ALT, AST levels and incidence of liver damage (H = 14.240 and 17.584, χ(2) = 49.547, P < 0.001). Patients with higher SF levels had higher ALT, AST levels and incidence of liver damage. Binary logistic regression analysis showed that hyperferritinemia (SF≥500 ng/ml) was the risk factor for dengue fever combined with liver damage (OR = 8.120, P < 0.001). Furthermore, ROC curve analysis showed that the AUC for SF to judge dengue fever combined liver damage was 0.846 (95% CI: 0.785-0.908), and the sensitivity and specificity when the SF cut-off value was 1 506 ng/ml were 74.8% and 83.3%. Conclusion: There is a certain correlation between the SF level and the degree of liver damage in acute stage of dengue fever patients, and hyperferritinemia is a risk factor for dengue fever combined with liver damage.

Abstract
Non-small-cell lung cancer (NSCLC) remains the leading cause of cancer-related death worldwide. Accumulating research has highlighted the ability of exosome-encapsulated microRNAs (miRNAs or miRs) as potential circulating biomarkers for lung cancer. The current study aimed to evaluate the clinical significance of serum-derived exosomal miR-let-7e as a biomarker in the metastasis of NSCLC. Initially, the expression of miR-let-7e, SUV39H2, and CDH1 in human NSCLC tissues and exosomes isolated from the serum of NSCLC patients was determined by RT-qPCR, demonstrating that miR-let-7e was downregulated in NSCLC tissues and serum-derived exosomes, while SUV39H2 was upregulated in NSCLC tissues. Kaplan-Meier method revealed that both lower miR-let-7e expression and higher SUV39H2 expression were correlated with a lower survival rate of NSCLC patients. Next, SUV39H2 was predicted and validated to be a target of miR-let-7e using dual-luciferase reporter assay. NSCLC H1299 cells following ectopic expression and depletion experiments of miR-let-7e and SUV39H2 were treated with serum-derived exosomes, after which the viability, migration, and invasion of H1299 cells were detected using CCK-8 and Transwell assays. Further, in vivo experiments were conducted to elucidate the effect of exosomal miR-let-7e on tumorigenesis. Results revealed that miR-let-7e overexpression in serum-derived exosomes inhibited SUV39H2, resulting in impaired cell viability, migration, and invasion in vitro as well as delayed tumor growth in vivo. In conclusion, the key findings of the current study demonstrate that exosomal miR-let-7e from serum possesses anticarcinogenic properties against NSCLC via the SUV39H2/LSD1/CDH1 axis.

Abstract
Edge turbulence is important for plasma confinement, so the gas puffing imaging (GPI) diagnostic was proposed on the J-TEXT tokamak for the two-dimensional measurement of turbulence in the edge region. GPI is a diagnostic of plasma turbulence that uses a puff of neutral gas at the plasma edge to increase the local visible light emission for improved space-time resolution of plasma fluctuations. Considering the conditions of J-TEXT, the observation area is 21° away from the position of the optical system in the toroidal direction, and the observation area is 10 cm × 10 cm inside and outside the last closed flux surface. To have a lower divergence of the gas flow, the gas puff nozzle is specially designed. An interface has been developed for operation. To photograph the line radiation generated by the neutral gas cloud along the magnetic field lines, the optical system is designed. It is composed of a quartz glass, mirrors, commercial lenses, filters, and high-speed cameras. The high-speed camera can capture the line radiation with a speed up to 180 000 frames/s with 256 pixels × 256 pixels and an exposure time of 5 µs. In a recent experiment, the new GPI diagnostic has obtained some preliminary pictures.

Abstract
Graphene has taken impressive roles in light manipulation and optical engineering. The most attractive advantage of graphene is its tunable conductivity that could be dynamically modulated by various means. In this paper, we show that the spin Hall shift of light is dynamically tunable via changing the Fermi level of the graphene-wrapped spheres. Such tunability is prominent when different modes interfere with each other, such as at the interference of electric and magnetic dipolar modes or at the interference of electric dipolar and electric quadrupole modes. The circular polarization degree in the near field clearly demonstrates the strength of spin-orbit interaction, which is associated with spin Hall shift of light in the far-field. In addition, the spin Hall effect is shown in far-field detection plane and should be observed in experiment. Our results provide insights into how the spin Hall effect could be tuned and add new perspective in designing optical super-resolution imaging techniques.

Abstract
Objective: To investigate the correlation between cone-beam CT (CBCT) morphological stage of midpalatal suture (MPS) and cervical vertebral maturation stage (CS) of Chinese children and youth. Methods: This study was a retrospective observational study. A total of 1 076 CBCT images (male: 401, female: 675, age≥ 6.0 years old and<21.0 years old) taken from January 2013 to April 2018 in Peking University School and Hospital of Stomatology were included. MPS and CS of each sample were recorded according to previous studies. MPS included five stages: MPS 1, MPS 2, MPS 3, MPS 4s1 (substage), MPS 4s2 (substage), and MPS 5. CS included six stages: CS 1-6. Correlation between MPS and CS (ordinal categorical variables) was investigated by Spearman correlation coefficient and diagnostic test analysis. Results: Spearman coefficient between CS and MPS was 0.803. Diagnostic pairs with the best diagnostic performance include: CS 6-MPS 5, CS 5-MPS 4s2, CS 1-MPS 1, CS 4-MPS 4s1, CS 2-MPS 1, CS 3-MPS 3. The 90.9% (309/340) of individuals at CS 1-3 were at MPS 1-3 and 9.1% (31/340) were at MPS 4s1. The 33.0% (107/324) of individuals at CS 4 were at MPS 3 and 46.6% (151/324) were at MPS 4s1. Conclusions: CS has a close relationship with MPS. Individuals at CS 4 are recommended to take pre-treatment CBCT, so as to estimate feasibility of skeletal expansion with traditional tooth-borne rapid maxillary expansion.

Abstract
Background Primary percutaneous coronary intervention (PCI) has been the standard reperfusion strategy for patients with acute myocardial infarction (AMI) in the contemporary era. Meanwhile, the incidence and prognosis of left ventricular aneurysm (LVA) in AMI patients remain ambiguous. The aim of the current study is to identify the predictor and long-term prognosis of LVA in patients with acute anterior myocardial infarction. Methods We prospectively enrolled 942 consecutive patients with acute anterior myocardial infarction who were treated by primary PCI. The baseline characteristics, procedural features, and one-year clinical outcomes were compared between the patients with and without LVA. The primary endpoint of major adverse cardiovascular and cerebrovascular events (MACCEs) was defined as a composite of cardiac death, target vessel revascularization, and ischemic stroke. Multiple logistic regression was applied to predict LVA formation and the receiver operating characteristic (ROC) curves were plotted to evaluate the accuracy of the multivariate analysis model. Results The general incidence of LVA was 15.92%. At one-year clinical follow-up, patients in the LVA group had significantly higher incidence of MACCEs (15.33% vs. 6.44%, P<0.01), mainly driven by an increased incidence of cardiac death (8.00% vs. 2.78%, P<0.01), target vessel revascularization (5.33% vs. 2.27%, P=0.03), and ischemic stroke (4.00% vs. 1.39%, P=0.03). Multivariate analysis found that longer symptom-to-balloon time (S2B) [odds ratio (OR): 1.16, 95% confidence interval (CI): 1.11–1.21, P<0.01], higher initial and residual SYNTAX score (iSS, OR: 1.19, 95% CI: 1.14–1.24, P<0.01; rSS, OR: 1.33, 95% CI: 1.22–1.45, P<0.01), lower left ventricular ejection fraction (LVEF) (OR: 1.15, 95% CI: 1.11–1.18, P<0.01), and persistent ST segment elevation (OR: 1.89, 95% CI: 1.06–3.38, P=0.03) were independent predictors of LVA formation. Conclusions LVA is still common in patients with acute anterior myocardial infarction in the contemporary PCI era, and the prognosis of these patients was significantly worse during the one-year clinical follow-up. Strategies of prompt reperfusion and complete revascularization may be helpful in preventing LVA formation and improving clinical outcomes.

Abstract
Candida albicans is one of the most common clinical pathogenic microorganisms and it is becoming a serious health threat, particularly to immunocompromised populations. Drug resistance of Candida species has also frequently emerged, and combination therapy for fungal infections has attracted considerable attention. In this study, we established the Qinling Mountains myxobacterial secondary metabolites library and a synergic assay in combination with ketoconazole against C. albicans was introduced for metabolites screening. Two active compounds with synergic anticandidal activities were obtained, which were identified as trans-resveratrol and cis-resveratrol. According to our study, resveratrol can reduce the dosage to 1/64 of ketoconazole as well as itraconazole. Furthermore, synergistic anticandidal activity of resveratrol combined with azoles was verified against a panel of clinical C. albicans isolates, and the combination strategy enhanced the azoles susceptibility of three fluconazole-resistant isolates. These findings suggest that resveratrol enhances the efficacy of azoles and provides a promising application in therapy of C. albicans infection.

Abstract
BACKGROUND Lung cancer is one of the most aggressive malignancies and the efficacy of chemotherapy or concurrent chemoradiation is limited in clinical application. Curcumin has been reported to block cancer development by modulating multiple signaling pathways. However, whether curcumin can inhibit gemcitabine-resistant non-small cell lung cancer through regulation of lncRNA and the involved molecular mechanisms are rarely reported. MATERIALS AND METHODS MTT assay, clonogenic assay, apoptosis assay, qRT-PCR, Western blotting, immunohistochemistry, xenograft experiment were carried out in the present study. RESULTS The results showed that curcumin suppressed gemcitabine-resistant non-small cell lung cancer cell proliferation and induced apoptosis. Curcumin upregulated the expression of lncRNA-MEG3 and PTEN, and MEG3 overexpression could increase the level of PTEN expression, while MEG3 knockdown decreased the level of PTEN expression in gemcitabine-resistant non-small cell lung cancer cells. Curcumin treatment failed to inhibit the proliferation and induce apoptosis in MEG3 knockdown or PTEN knockdown cells. CONCLUSIONS These findings show the antitumor activity of curcumin for potential clinical application in gemcitabine-resistant non-small cell lung cancer treatment.

Abstract
Background Non-small cell lung cancer (NSCLC) is a common type of lung cancer. Extracellular vehicles (EVs) are nano-sized particles containing proteins, lipids, and miRNAs secreted by various cells, which play important roles in the development of lung cancer by regulating a wide range of signaling pathways. This study focused on elucidating a potential mechanism by which EVs promote the development of NSCLC. Methods Expression levels of miR-744, SUV39H1, Smad9, and BMP4 in clinical tissue samples of NSCLC patients and cell lines were quantified by RT-qPCR and/or western blot analysis. The interaction between SUV39H1 and miR-744 was identified by dual-luciferase reporter assay. miR-744, SUV39H1, and BMP4 expression levels were modulated in A549 and H460 cells, in order to evaluate their effects on cell proliferation, colony formation and cell cycle. A NSCLC xenograft mouse model was used to verify the in vitro findings. NSCLC cell-derived EVs and normal bronchial epithelial cell-derived EVs were isolated and their roles in NSCLC development were evaluated in vivo and in vitro. Results miR-744 expression was lower in cancer cell-derived derived EVs than in normal lung epithelial cell-derived EVs. Reduced miR-744 expression in EVs upregulated SUV39H1 in NSCLC cells and further increased BMP4 levels to promote NSCLC development. BMP4 was upregulated in NSCLC cells upon suppression of Smad9 mediated by SUV39H1. Reduced miR-744 expression transferred from cancer cell-derived EVs into NSCLC cells enhanced cancer development. Conclusion Overall, our findings unveiled a mechanism whereby miR-744 delivered by NSCLC-derived EVs upregulated SUV39H1, activating the Smad9/BMP9 axis and thus promoted cancer development.

Abstract
Objective: To observe the efficacy and safety of sirolimus combined with calcineurin inhibitor (CNI) in the treatment of glucocorticoid resistant/dependent extensive chronic graft-versus-host disease (cGVHD) . Methods: A total of 27 patients with steroid-resistant/steroid-dependent extensive cGVHD from November 2015 to January 2019 were enrolled and given sirolimus capsules combined with cyclosporine or tacrolimus to observe the clinical efficacy and adverse events. Results: The median duration of medication was 14.2 months and the mean duration was 16.7 months. The median follow-up time was 20.1 months (12.9-46.1 months) . Following the 6-month follow-up, 3 cases achieved complete response (CR) and 12 cases partial response (PR) . The overall response rate (ORR) was 55.6% ; for progression-free survival (PFS) , PFS-6 reached 88.9% (24/27) , and for overall survival (OS) , OS-6 was 100% . At the 1-year follow-up, there were 5 cases of CR and 11 cases of PR, ORR was 59.3% , PFS-12 reached 62.9% (17/27) , and OS-12 was 100% . The subgroup analysis found that the program was more effective for cGVHD in male donors and the target organ analysis had an advantage in the treatment of oral cavity, skin, and liver rejection. Adverse events were observed: hyperlipidemia 11.1% , oral ulcer 7.4% , fungal infection 11.1% , liver injury 3.7% , renal insufficiency 0, and no new CMV and EB viremia. Conclusion: Sirolimus combined with calcineurin inhibitors is effective in treating steroid-resistant/steroid-dependent extensive cGVHD, especially because adverse reactions (renal toxicity, CMV, EBV infection) are low in number, which is suitable for long-term treatment of cGVHD.

Abstract
To assess the correlation between thyroid function and glucolipid metabolism in type 1 diabetic adults. A retrospective analysis was conducted in 230 type 1 diabetic adults who were hospitalized in the Department of Endocrinology of Shandong Provincial Hospital Affiliated to Shandong University from January 2008 to January 2020. It showed that thyroid stimulating hormone(TSH) was significantly positively correlated with total cholesterol (TC) (r=0.239), triglycerides (TG) (r=0.166) and low-density lipoprotein cholesterol (LDL-C) (r=0.249), respectively (all P<0.05). Free triiodothyronine (FT3) was significantly negatively correlated with fasting plasma glucose (FPG) (r=-0.272), glycated hemoglobin (HbA1c) (r=-0.240), TC (r=-0.197) and LDL-C (r=-0.220), respectively (all P<0.05). Free thyroxine (FT4) was negatively correlated with TC (r=-0.171) and LDL-C (r=-0.170), respectively (all P<0.05). TC was an independent predictor of TSH, FT3 and FT4, FT3 and FT4 were independent predictors of HbA1c. TSH was an independent predictor of TC, TG and LDL-C. Thyroid function is closely related to glucolipid metabolism in type 1 diabetic adults.

Abstract
BACKGROUND Evidence suggests that arteriosclerosis and sarcopenia (decreased muscle mass) share some of their many causes. However, after controlling for confounding factors, it is unclear whether the presence of arteriosclerosis correlates with sarcopenia. OBJECTIVES The aim of this paper is to explore whether sarcopenia is associated with arteriosclerosis. DESIGN A multicenter cross-sectional community-based study. MATERIALS AND METHODS A total of 2511 elderly subjects from six Chinese community health service centers in Anhui province were surveyed through an e-health promotion system to collect basic data and measurements of brachial-ankle pulse wave (baPWV), body composition, and handgrip strength (HGS). Pearson's correlation and binary logistic regression analyses were performed to identify associations between sarcopenia and high baPWV. RESULTS The prevalence rates of sarcopenia were 12.9% in men and 15.3% in women according to the 2019 standard of Asian Working Group for Sarcopenia. Among subjects with high baPWV, the proportion of sarcopenia was higher compared to those with normal baPWV (men: 17.7% vs. 3.7%; women: 20.4% vs. 4.9%, both p<0.001). Binary logistic regression analysis revealed that sarcopenia was associated with high baPWV (p<0.0001, odds ratio=1.619) after adjusting for confounding factors. HGS slightly and negatively correlated with baPWV (-0.19 in men and -0.18 in women). CONCLUSIONS The intertwined pathophysiological mechanisms shared by arteriosclerosis and sarcopenia are potential targets for future interventions to reduce morbimortality in subjects with both disorders. Upcoming prospective studies and clinical trials are expected to advance these findings.

Abstract
OBJECTIVE Intracerebral hemorrhage (ICH) is a devastating cerebrovascular disease of the central nervous system. In this study, we aimed to investigate plasma ZCCHC14 expression and its correlation with the diagnosis, prognosis, and clinical features of ICH. PATIENTS AND METHODS The plasma levels of ZCCHC14, TNF-α, IL-6, and IL-10 were dynamically detected among 130 ICH patients and 60 corresponding healthy subjects. A receiver operating characteristic (ROC) curve was used for the statistical analysis of the diagnostic and prognostic efficacy of ICH. RESULTS Hypertension (p = 0.005), ARB application (p = 0.014), ZCCHC14 level (p < 0.001), TNF-α (p < 0.001), IL-6 (p < 0.001), and IL-10 (p < 0.001) were found to be different between ICH patients and healthy controls. Multiple logistic regression analysis indicated that ZCCHC14 levels at admission were significantly different between the two groups (p = 0.002, OR = 0.440, 95% CI 0.290-0.718). Plasma ZCCHC14 levels dynamically changed, increasing at admission, and peaking on day 7. ZCCHC14 was a potential diagnostic marker for ICH (AUC = 0.953, p < 0.0001, 95% CI: 0.901-1.004) with a specificity and sensitivity of 84.6% and 95.5%, respectively. The plasma ZCCHC14 level was negatively correlated with IL-6 concentration (p = 0.024, r = -0.311) but was positively correlated with IL-10 concentration (p = 0.041, r = 0.298). Furthermore, the plasma ZCCHC14 level was correlated with hypertension (p = 0.005), GOS (p = 0.025), bleeding volume (p < 0.001), midline shift (p = 0.003), and poor outcome (p = 0.006). The low ZCCHC14 expression group had poorer outcomes (death or severe disability) than high ZCCHC14 expression group (Breslow, p < 0.001). CONCLUSIONS We found that the plasma ZCCHC14 level might be a potential biomarker for both the early diagnosis of and prediction of outcomes in ICH.

Abstract
The present study aimed to investigate the expression and predictive value of serum hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) in patients with burns following treatment. A total of 84 patients with burns treated in Jinan City People's Hospital (Jinan, China) between June 2015 and August 2017 were selected and their clinical information was collected. The expression levels of HIF-1α and VEGF before and after treatment were detected via ELISA, and HIF-1α and VEGF levels in patients with effective and ineffective treatment were compared. The predictive values of HIF-1α and VEGF in clinical efficacy were determined using receiver operating characteristic (ROC) curves, and independent risk factors affecting treatment inefficacy were analyzed via multivariate logistic regression. It was revealed that HIF-1α decreased significantly (P<0.05) while VEGF significantly increased in patients after treatment. Patients with effective treatment presented significantly lower HIF-1α levels and higher VEGF levels compared with those with ineffective treatment. The ROC curve indicated that the area under the curve (AUC) of HIF-1α for treatment efficacy was 0.795, the 95% CI was 0.666-0.924, the specificity and sensitivity were 68.75 and 80.88%, respectively, and the Youden index was 49.63%. For VEGF, the AUC, 95% CI, specificity, sensitivity and Youden index were 0.826, 0.725-0.928, 68.75, 82.35 and 51.10% respectively. Moreover, under the joint detection of HIF-1α and VEGF, the AUC was 0.847, 95% CI was 0.746-0.947, specificity and sensitivity were 87.50 and 66.18%, respectively, with a Youden index of 53.68%. Multivariate analysis demonstrated that higher HIF-1α level, lower VEGF level and higher burn degree before treatment were independent risk factors for treatment inefficacy. HIF-1α levels decreased and VEGF levels increased in burn patients after treatment. HIF-1α and VEGF before treatment may therefore serve as predictors for treatment efficacy.

Abstract
BACKGROUND: Occupational exposure-related risk of Mycobacterium tuberculosis infection has been reported for village doctors in China. This prospective study aims to estimate the infection acquisition in this key population.METHODS: At baseline, all village doctors registered in Zhongmu County were tested by QuantiFERON®-TB Gold In-Tube (QFT) and QuantiFERON®-TB Gold Plus (QFT-Plus) in parallel. Those negatives for either of the tests were retested to identify conversions at the 2-year follow-up investigation.RESULTS: A total of 367 eligible participants completed the 2-year follow-up survey with frequency of conversion of 5.0% (18/361) for QFT and 6.1% (21/343) for QFT-Plus. The agreement of follow-up results between the tests was 93.2% with a κ coefficient of 0.43 (95%CI 0.20-0.65). Among QFT-Plus convertors, the difference between TB1 and TB2 tubes (TB2-TB1) was significantly increased as compared with baseline results (P = 0.039). Participants from the villages with occurrence of microbiologically confirmed pulmonary TB showed higher frequency of QFT conversions (11.0% vs. 3.2%, P = 0.011) and QFT-Plus conversions (12.3% vs. 4.4%, P = 0.027) than those from the villages without occurrence.CONCLUSION: Our results consistently suggest that capability on occupational protection and M. tuberculosis infection control should be improved in village doctors in China.

Abstract
Objective: To investigate the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) with pharyngeal symptoms. Methods: From January 10 to May 15, 2020, clinical data of 1 228 patients with COVID-19 in Renmin Hospital of Wuhan University was collected (554 males and 674 females, with the range of age from 10 to 95 years old, the average age was 55.2 years old). The patients were divided into pharyngeal symptoms group (PS, 126 cases) and non-pharyngeal symptoms group (Non-PS, 1 102 cases) according to the presence or absence of pharyngeal symptoms such as pharyngalgia, pharyngeal dryness, pharyngeal itching, and pharyngeal foreign body sensation. The clinical data in terms of age, sex, medical history, duration of symptoms, treatment time, clinical classification, pulmonary imaging findings, whole blood cell count, serum hypersensitivity C-reactive protein, C-reactive protein, procalcitonin were statistically analyzed between the two groups. Chi-square, Fisher's exact test and Mann-Whitney U test were used for statistical analysis. Results: The most common pharyngeal symptoms were pharyngalgia (59.52%, 75/126), followed by foreign body sensation (23.02%, 29/126), pharyngeal dryness (8.73%, 11/126), and itching (8.73%, 11/126). The median age of the patients in the PS group was 51.50 years old, which was less than 57.50 years old in the non-PS group, showing a significant difference (P<0.05). The female cases accounted for 65.08% (82/126), which was higher than 53.72% (592/1 102) of the non-PS group (P<0.05). The incidence of bilateral lung inflammation confirmed by CT images was 73.81% (93/126), which was significantly lower than 83.48% (920/1 102) in the non-PS group (P<0.05). No significant differences were shown in the proportion of patients with clinical types, treatment days, duration of symptoms, white blood cell count, lymphocyte count, lymphocyte percentage, eosinophil count, eosinophil percentage, hypersensitive C-reactive protein, C-reactive protein, D-dimer, procalcitonin and other indicators (P>0.05). Conclusions: The incidence of pharyngeal symptoms in patients with COVID-19 is 10.26%. Most of these symptoms occur before or at the same time as the common symptoms of the disease. Therefore, patients with such symptoms may bring a greater risk of infection to otolaryngologist. According to the current clinical classification criteria, pharyngeal symptoms have no obvious correlation with the degree of the disease; but the presence of pharyngeal symptoms may suggest a milder clinical presentation and a better prognosis.

Abstract
Aptamers are special types of single-stranded DNA generated by a process called systematic evolution of ligands by exponential enrichment (SELEX). Due to significant advances in the chemical synthesis and biotechnological production, aptamers have gained considerable attention as versatile building blocks for the next generation of soft materials. Hydrogels are high water-retainable materials with a three-dimensional (3D) polymeric network. Aptamers, as a vital element, have greatly expanded the applications of hydrogels. Due to their biocompatibility, selective binding, and molecular recognition, aptamer-based hydrogels can be utilized for bioanalytical and biomedical applications. In this review, we focus on the latest strategies of aptamer-based hydrogels in bioanalytical and biomedical applications. We begin this review with an overview of the underlying design principles for the construction of aptamer-based hydrogels. Next, we will discuss some bioanalytical and biomedical applications of aptamer-based hydrogel including biosensing, target capture and release, logic devices, gene and cancer therapy. Finally, the recent progress of aptamer-based hydrogels is discussed, along with challenges and future perspectives.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has resulted in millions of patients
infected worldwide and indirectly affecting even more individuals through disruption of
daily living. Long-term adverse outcomes have been reported with similar diseases from
other coronaviruses, namely Middle East Respiratory Syndrome (MERS) and Severe Acute
Respiratory Syndrome (SARS). Emerging evidence suggests that COVID-19 adversely affects
different systems in the human body. This review summarizes the current evidence on the
short-term adverse health outcomes and assesses the risk of potential long-term adverse
outcomes of COVID-19. Major adverse outcomes were found to affect different body systems:
immune system (including but not limited to Guillain-Barré syndrome and paediatric
inflammatory multisystem syndrome), respiratory system (lung fibrosis and pulmonary
thromboembolism), cardiovascular system (cardiomyopathy and coagulopathy), neurological
system (sensory dysfunction and stroke), as well as cutaneous and gastrointestinal
manifestations, impaired hepatic and renal function. Mental health in patients with
COVID-19 was also found to be adversely affected. The burden of caring for COVID-19
survivors is likely to be huge. Therefore, it is important for policy makers to develop
comprehensive strategies in providing resources and capacity in the healthcare system.
Future epidemiological studies are needed to further investigate the long-term impact on
COVID-19 survivors.

Abstract
Objective: To analysis the clinical characteristics and to summarize therapy experience of pediatric patients with cardiac syncope caused by anomalous origin of the left coronary artery from the right sinus (ALCA-R). Methods: We retrospectively analyzed the clinical data including clinical manifestations, myocardial injury biomarkers, radiological features, treatments and prognoses of pediatric patients with ALCA-R who were admitted to Beijing Children's Hospital from November 2015 to June 2018. Results: Four female patients were included in this analysis, age of onset was 7 to 14 years. All the patients presented with exercise-induced syncope and acute myocardial infarction. During the course, three patients presented with acute left heart failure, and one patient had history of sudden cardiac arrest. Laboratory data showed significant elevation of both the creatine kinase and troponin levels in four patients. All electrocardiogram (ECG) showed left main coronary artery occlusion, echocardiography suggested the possible anomalous origin of the left coronary artery in one child. Coronary CT angiography (CTA) revealed there was no coronary ostium in the left coronary sinus, and the left coronary artery had an anomalous origin from the right sinus. The left main coronary artery passed between the ascending artery and the root of the main pulmonary artery, which was compressed by these two large vessels. Two patients underwent cardiac magnetic resonance examination, which detected late gadolinium enhancement in ALCA-R with an interarterial course. Unroofing of the left coronary ostium (cut-back procedure) was performed in two patients, and the other two patients who were not operated were recommended to restrict their physical activities. During a regular follow-up period of 12-43 months, all the children survived without recurrent cardiovascular event. Conclusion: If an adolescent presents with exercise-induced syncope, acute myocardial infarction and even sudden death, and ECG shows left main coronary artery occlusion characteristics, we should consider the possibility of developmental abnormality of coronary artery, particularly the ALCA-R. Once diagnosed as ALCA-R, patients should be recommended to avoid strenuous activities,early recognition and surgical treatment are imperative for these patients.

Abstract
OBJECTIVE To explore the effects of long non-coding ribonucleic acid (lncRNA) maternally expressed gene 3 (MEG3) on the proliferation and apoptosis of hypoxic myocardial cells by regulating the expression of forkhead box O1 (FoxO1). MATERIALS AND METHODS The myocardial A10 cell lines were divided into myocardial cell group (group A), hypoxic myocardial cell group (group B), and hypoxic myocardial cell + transfection with lncRNA MEG3 mimic group (group C). The correlations of the adenosine triphosphate (ATP) concentration, the degree of apoptosis, and the proliferation with FoxO1 and FoxO3a proteins in the cells were observed via ATP assay, Cell Counting Kit-8 (CCK-8) assay, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay, Western blotting, and quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR), respectively. RESULTS The ATP concentration in myocardial cells was the highest in group A (p<0.05), and it was higher in group B than that in group C (p<0.05). The results of the CCK-8 assay showed that the proliferation rate of the myocardial cells was the highest in group A and the lowest in group C (p<0.05), and it was significantly increased in group B compared with that in group C (p<0.05). The results of the TUNEL assay revealed that the normal cells displayed the purple color, and apoptotic cells displayed the green color. The myocardial cells were arranged orderly, and the number of apoptotic cells was smaller in group A, the number of apoptotic cells was significantly larger in group B than that in group A, and it was the largest in group C (p<0.05). Moreover, the results of Western blotting manifested that the concentrations of FoxO1 and FoxO3 proteins in myocardial cells were the lowest in group A (p<0.05), and they were significantly higher in group C than those in group B (p<0.05). According to the results of qRT-PCR, the mRNA expressions of FoxO1 and FoxO3 in myocardial cells were the lowest in group A (p<0.05), and they were remarkably lower in group B than those in group C (p<0.05). CONCLUSIONS LncRNA MEG3 can increase the activity of FoxO1 to promote myocardial apoptosis in a hypoxic environment.

Abstract
The vehicular Internet of Things (IoT) comprises enabling technologies for a large number of important applications including collaborative autonomous driving and advanced transportation systems. Due to the mobility of vehicles, strict application requirements, and limited communication resources, the conventional centralized control fails to provide sufficient quality of service for connected vehicles, so a decentralized approach is required in the vicinity to satisfy the requirements of delay-sensitive and mission-critical applications. A decentralized system is also more resistant to the single point of failure problem and malicious attacks. Blockchain technology has been attracting great interest due to its capability of achieving a decentralized, transparent, and tamper-resistant system. There are many studies focusing on the use of blockchain in managing data and transactions in vehicular environments. However, the application of blockchain in vehicular environments also faces some technical challenges. In this paper, we first explain the fundamentals of blockchain and vehicular IoT. Then, we conduct a literature review on the existing research efforts of the blockchain for vehicular IoT by discussing the research problems and technical issues. After that, we point out some future research issues considering the characteristics of both blockchain and vehicular IoT.

Abstract
Cosmological models in which dark matter consists of cold elementary particles predict that the dark halo population should extend to masses many orders of magnitude below those at which galaxies can form1-3. Here we report a cosmological simulation of the formation of present-day haloes over the full range of observed halo masses (20 orders of magnitude) when dark matter is assumed to be in the form of weakly interacting massive particles of mass approximately 100 gigaelectronvolts. The simulation has a full dynamic range of 30 orders of magnitude in mass and resolves the internal structure of hundreds of Earth-mass haloes in as much detail as it does for hundreds of rich galaxy clusters. We find that halo density profiles are universal over the entire mass range and are well described by simple two-parameter fitting formulae4,5. Halo mass and concentration are tightly related in a way that depends on cosmology and on the nature of the dark matter. For a fixed mass, the concentration is independent of the local environment for haloes less massive than those of typical galaxies. Haloes over the mass range of 10-3 to 1011 solar masses contribute about equally (per logarithmic interval) to the luminosity produced by dark matter annihilation, which we find to be smaller than all previous estimates by factors ranging up to one thousand3.

Abstract
BACKGROUND The relationship between cancer and venous thromboembolic disease (VTD) are complex because the activated coagulation factors are not only involved in thrombosis but also in malignant processes, such as angiogenesis and metastasis. OBJECTIVE To compare phenotypes of extracellular vesicles (EVs), and levels of D-dimer, soluble P-selectin (sP-selectin) and antigenic tissue factor (TF) between unprovoked VTD patients, who did not develop cancer during one-year follow-up, and those with advanced stage of cancer but not associated with VTD. METHODS A prospective study in which we included 138 unprovoked VTD patients and 67 advanced cancer patients, who did not develop thrombosis. Levels of EVs of different cellular origin (platelet, endothelium and leukocyte), EVs positive for tissue factor (TF) and P-selectin glycoprotein ligand 1 were quantified by flow cytometry. D-dimer, soluble P-selectin (sP-selectin) and antigenic TF were determined by ELISA. RESULTS TF-positive EVs, D-dimer, and sP-selectin were markedly elevated in unprovoked VTD patients compared to cancer patients without association with thrombosis. CONCLUSIONS Levels of TF-positive EVs, D-dimer and sP-selectin are able to discriminate between unprovoked VTD patients not related to cancer and cancer patients not associated with VTD. These results could lead to the application of EVs as biomarkers of both diseases. Key messages: Circulating EVs, specifically TF-positive EVs, in combination with plasmatic markers of hypercoagulable states, such as D-dimer, sP-selectin and antigen TF, are able to discriminate between cancer patients without thrombosis and patients with unprovoked VTD. Research fields could be opened. Future studies will assess if these biomarkers together serve as predicting thrombotic events in cancer populations.

Abstract
PURPOSE The clinical outcome after in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is diverse in infertility patients with polycystic ovary syndrome (PCOS). The aim of this study was to develop a nomogram based on an association of patients' characteristics to predict the live birth rate in PCOS patients. METHODS All women in a public university hospital who attempted to conceive by IVF/ICSI for PCOS infertility from January 2014 to October 2018 were included. The nomogram was built from a training cohort of 178 consecutive patients and tested on an independent validation cohort of 81 patients. PCOS was confirmed in all participants. RESULTS Three variates significantly associated with live birth rate of PCOS patients were BMI, total serum cholesterol (TC) and basal FSH. This predictive model built on the basis of BMI, TC, basal FSH, type of embryo transferred and age showed good calibration and discriminatory abilities, with an area under the curve (AUC) of 0.708 (95% CI 0.632-0.785) for the training cohort. The nomogram showed satisfactory goodness-of-fit and discrimination abilities in the independent validation cohort, with an AUC of 0.686 (95% CI 0.556-0.815). CONCLUSION Our simple evidence-based nomogram presents graphically risk factors and prognostic models for IVF/ICSI outcomes in patients with PCOS, which can offer useful guidance to clinicians and patients for individual adjuvant therapy.

Abstract
BACKGROUND Thyroid-stimulating hormone (TSH) plays an important role in the regulation of lipid metabolism. However, little is known about the role that exosomes play in the process of TSH-induced lipotoxicity in non-alcoholic fatty liver disease (NAFLD). As a preliminary step, the present study set out to investigate alterations in protein expression in exosomes derived from TSH-stimulated HepG2 cells. METHODS HepG2 cells were treated with TSH, exosomes were collected, and proteins were identified by mass spectrometry (MS). Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genome (KEGG) pathway analysis were performed to analyze the identified proteins. RESULTS TSH treatment significantly increased exosomal production and changed the exosomal proteomic profile in HepG2 cells. Among the 1728 proteins, 140 identified proteins were upregulated and seven proteins were downregulated. GO analysis and KEGG analysis revealed that these proteins were involved in multiple processes including metabolism, apoptosis, and inflammation. CONCLUSION Our preliminary study demonstrated that exosomes derived from TSH-stimulated hepatocytes were increased and showed a specific altered spectrum of proteins, many of which were involved in metabolism, signal transduction, apoptosis, and inflammation. This study offers new insights into the pathogenesis of TSH-induced lipotoxicity in NAFLD.

Abstract
Intrinsically photosensitive retinal ganglion cells (ipRGCs) are atypical photoreceptors that are different from classical cone and rod cells. The primary role of ipRGCs is to signal light for largely subconscious, non-image vision such as photoentrainment of circadian rhythm and pupillary light reflex. Recent researches have revealed additional roles for ipRGCs in communication with synapses around, conscious vision reception and pathogenesis of some diseases. Here we review the research advances of morphology, functions and clinical applications of ipRGCs. (Chin J Ophthalmol, 2020, 56: 308-312).

Abstract
The topological magnetoelectric effect is associated with the photonic spin-orbit interaction. However, due to the proportionate fine structure constant of the topological term, the topological magnetoelectric effect is usually weak. In this paper, we demonstrate that the axion term enables manipulation of the spin Hall shift of light around Fano resonance. And, the excited surface plasmon near the nanoparticle's interface could enhance the topological magnetoelectric effect for several orders. Numerical simulation of near field and far-field scattering confirms our theoretical results. Our work may pave the way to exploit the topological magnetoelectric effect in practical applications, such as optical sensing and nanoprobing.

Abstract
PURPOSE OF REVIEW Maternal hypertension is a common and serious condition associated with increased maternal and foetal morbidity and mortality, with early detection and management improving outcomes. RECENT FINDINGS Blood pressure (BP) changes of pre-eclampsia are defined after 20 gestational weeks, while haemodynamic changes can be detected at 5-11 weeks using a specialised non-invasive Doppler stroke volume (SV) monitor. Thus, advanced haemodynamic monitoring allows for physiologically precise identification of circulatory abnormalities, and implementation of appropriate therapy within the first trimester. We measured the oscillometric BP and advanced haemodynamics (USCOM 1A) of 3 unselected women with singleton pregnancies, consecutively listed for therapeutic induction for maternal hypertension at 32-41 weeks gestational age. While the BP's of the patients varied, it was the haemodynamics, particularly SV, cardiac output, systemic vascular resistance, Smith Madigan Inotropy Index, and oxygen deliver, that identified differing patterns of circulatory dysfunction, therapeutic objectives, and predicted post-partum complications of the mother and child. First trimester screening of maternal haemodynamics may allow for earlier detection of circulatory derangements, selection of patient precise interventions, and improved maternal-foetal outcomes.

Abstract
Objective: The objective of the study was systematically summarized the current status of the hepatocellular carcinoma (HCC) screening guidelines, and evaluated the HCC screening guidelines according to the authoritative framework of cancer screening guidelines of authoritative institutions, which provided important value for the formulation of HCC screening evidence-based guidelines. Methods: Literature search was conducted in multiple databases from their inception dates to January 3, 2019. In addition, we sought relevant websites further was searched to identify potentially eligible studies. Two reviewers independently screened literature and extracted data. Qualitative description of the basic information, recommendations of HCC screening, source of evidence and update progress of the HCC screening guidelines was conducted. Results: At present, there were no independent HCC screening guidelines worldwide. There were only 17 clinical practice HCC guidelines briefly provided the recommendation of HCC screening. Current HCC screening guidelines only recommended screening for high-risk groups of HCC. All guidelines have identified patients with chronic hepatitis B, hepatitis C and cirrhosis as high-risk groups for HCC. Most of guidelines recommended screening intervals was 6 months. The latest guidelines in Europe and the United States recommended ultrasound for screening HCC. The combination of ultrasound and AFP was recommended in the Asian guidelines. Currently, HCC screening guidelines mainly recommended screening strategies based on factors such as risk of HCC, accuracy of screening modality, screening cost, etc.. The key factors such as screening efficacy and safety have not yet been considered comprehensively. Conclusions: There were no independent HCC screening guidelines worldwide. Only some clinical practice HCC guidelines briefly mentioned HCC screening. Currently, the guidelines only recommend screening for high-risk groups of HCC, with a screening interval of 6 months. There are differences in screening modalities recommended by European, American and Asian guidelines for screening HCC. It is suggested that the relevant institutions should formulate the evidence-based HCC screening guidelines by referring to the theoretical framework of other authoritative other cancer screening guidelines.

Abstract
Immune checkpoint inhibitor (ICI) has been emerged as a major breakthrough in tumor immunotherapy, but its unique mechanism of action has also led to a number of immune-related adverse events (irAE). Type 1 diabetes mellitus (T1DM) is one of the rarest irAEs. This paper reports a case of advanced malignant liver tumor-induced T1DM who received second-line anti-PD-1 therapy and showed initial symptoms of hyperosmolar coma and hyperglycemia. In addition, the relevant literature at home and abroad was collected and reviewed, and the clinical characteristics of T1DM induced by anti-PD-1 therapy were summarized with a view to achieve early detection, diagnosis and treatment.

Abstract
We theoretically study the optical bistability and tristability in plasmonic coated nanospheres containing the nonlinear plasmonic shell and the dielectric core with radial anisotropy. Based on self-consistent mean-field approximation, we establish the relationship between the local field in the shell and the applied incident field, taking into account the Lorentz local field. One or two optical bistabilities and even optical tristability can be observed. Especially, there are two critical geometric parameters between which two optical bistabilities exist. Physically, two optical bistablities result from the excitations of two surface plasmonic resonant modes in the inner and outer interfaces of coated nanospheres, which are well reflected from the spectral representation with two poles. Moreover, the involvement of the radial anisotropy is quite essential to realize the optical tristability. Further discussion on the field-induced tuning of the reflectance reveals the macroscopic properties of this nonlinear optical structure, which provides a potential candidate for designing multi-stable optical devices at the nanoscale.

Abstract
Background:In patients with primary Sjögren’s syndrome (pSS), both minor and major salivary glands are targets of the disease. Infiltration of salivary glands by immune cells is characteristic for pSS. However, significant inter- and intra-individual variation exists in the size and composition of the infiltrates. Potential differences between minor and major salivary glands in immune cell presence and inflammatory pathway activation are unclear. This knowledge is essential for clinical trial design and precision therapy.Objectives:To compare the transcriptome of paired labial and parotid salivary gland tissue of patients with pSS and non-SS sicca controls.Methods:Thirty-nine pSS patients and 20 age- and sex-matched non-SS sicca controls, who participated in a prospective diagnostic cohort[1], were included. All pSS patients fulfilled 2016 ACR-EULAR criteria. RNA was isolated from formalin-fixed, paraffin-embedded labial and parotid gland tissue sections from the same individuals. Complementary DNA libraries were prepared and sequenced. Biopsies with evidence of sclerosing chronic sialoadenitis or mucosa-associated lymphoid tissue lymphoma were excluded in the current analysis. For differential gene expression analysis, patients were subdivided in four categories: I) non-SS sicca without lymphocytic infiltration, II) non-SS sicca with aspecific infiltration, III) pSS with negative biopsy (focus score<1), IV) pSS with positive biopsy (focus score≥1). For each differentially expressed gene (DEG), a false detection rate (FDR) was calculated. FDR<0.05 was considered significant.Results:Principal component analysis (PCA) showed that only pSS patients with a positive biopsy (group IV) could be separated from the non-SS sicca patients based on gene expression. When comparing the labial and parotid gland transcriptome, resp. 798 and 1461 DEGs (FDR-adjusted p-value<0.05, log2 fold change >1) were identified between groups I and IV. The top differentially regulated genes were mostly related to T and B cells.CXCL13, CCR6, MS4A1(CD20), FCRL4andDAZLwere among the genes with the highest positive fold change in both glands of biopsy-positive pSS patients. Overall, there was a moderate to strong correlation between fold changes in labial and parotid glands (R2=0.58, p-value<0.0001). Between biopsy-negative and biopsy-positive pSS (groups III and IV), 226 and 962 DEGs were identified for labial and parotid gland tissue, respectively. Interestingly, we could not identify DEGs between biopsy-negative pSS (group III) and non-SS sicca patients (group I).Conclusion:The transcriptome of labial and parotid gland tissue from pSS patients with a positive biopsy is overall comparable, while salivary gland tissue from biopsy-negative pSS patients shows a comparable gene expression profile to non-SS sicca controls. These results indicate that different treatment strategies may be necessary for biopsy-negative and biopsy-positive pSS patients.References:[1]van Nimwegen JF,et al.Validation of the ACR-EULAR criteria for primary Sjögren’s syndrome in a Dutch prospective diagnostic cohort.Rheumatology (Oxford) 2018;57:818–25.Disclosure of Interests:Gwenny M.

Abstract
Abstract
Introduction
Daytime napping is common in elderly adults and has been associated with cognitive impairment. Prior studies have assessed napping at one time point, making it difficult to examine the longitudinal progression of napping and its association with cognitive aging. We examined objectively measured daytime napping longitudinally across different stages of Alzheimer’s disease (AD): from no cognitive impairment (NCI), to mild cognitive impairment (MCI), and to Alzheimer’s dementia.
Methods
We studied 1,066 participants (female: 810; age: 81.0±7.3 [SD]) in the Rush Memory and Aging Project who have been followed for up to 13 years. Motor activities of up to 10 days were recorded annually and used to assess napping objectively. We defined daytime napping episodes as segments between 10AM and 7PM with continuous zero-activity for ≥10min but <1h (to avoid off-wrist periods). Segments that were <5min apart were merged. Cognitive and clinical evaluations were administered annually to render a clinical diagnostic classification of NCI, MCI, or Alzheimer’s dementia. To examine how napping duration and frequency change with the progression of AD, we performed linear mixed-effects models with 2 change points anchored at the diagnoses of MCI and AD while adjusted for age, sex, and education.
Results
At baseline, participants had 1.44±0.04 (mean±standard error) naps with an accumulated duration of 35.0±1.1 min per day. Napping duration increased by 5.2±0.3 min and frequency increased by 0.21±0.01 times every year (both p<0.0001). The rate of increase was more than doubled after MCI diagnosis with an annual increase of 11.4±0.7 min in duration and 0.40±0.02 times in frequency (both p<0.0001); these were doubled further after AD diagnosis with an annual change of 26.3±3.1 min in duration and 0.84±0.08 times in frequency (both p<0.0001).
Conclusion
Daytime napping duration and frequency increase with aging, and the increase was accelerated with AD progression.
