Abstract
Objective: To investigate the characteristics of pulmonary function changes and its possible influencing factors in patients with pneumoconiosis. Methods: In December 2019, pneumoconiosis patients hospitalized in four departments of occupational diseases in Hunan Occupational Disease Prevention and Control Hospital from December 2015 to December 2016 were selected as subjects. Lung function including forced vital capacity (FVC) , FVC%, forced expiratory volume in one second (FEV1) , FEV1%, forced expiratory volume in one second / forced vital capacity (FEV1/FVC) , diffusion capacity of the lung foe carbon monoxide% (DLCO%) 、maximal expiratory rlow 75% (MEF75%) , maximal expiratory rlow 50% (MEF50%) and maximal expiratory rlow 25% (MEF25%) were tested, and collect their age, occupation history, smoking history and Chronic Obstructive Pulmonary Disease Self Rating Questionnaire (CAT) score. They were followed up after 3 years to analyze the 3-year decline rates of lung function indicators and their relationship with stage of pneumoconiosis, age, smoking index, baseline values of lung function and CAT score. Results: 265 cases were studied effectively. After 3 years, the values of 9 lung function indicators of pneumoconiosis patients were significantly lower than those of 3 years ago (P<0.05) . The decline rates of FEV1%, FEV1/FVC, MEF75%, MEF50% and MEF25% were positively correlated with the stage of pneumoconiosis (r=0.250, 0.290, 0.219, 0.280, 0.141, P<0.05) . The decline rates of FEV1% and MEF75% were positively correlated with smoking index (r=0.148, 0.152, P<0.05) . The decline rates of DLCO% and MEF25% were positively correlated with the baseline value of initial pulmonary function (r=0.276, 0.153, P<0.05) , while the decline rates of FEV1%, FEV1/FVC and MEF50% were negatively correlated with the baseline values of initial pulmonary function (r=-0.215, -0.146, -0.214, P<0.05) . The decline rates of FVC%, FEV1%, MEF75% and MEF50% were positively correlated with the changes of CAT scores (r=0.147, 0.208, 0.210, 0.196, P<0.05) . Logistic regression analysis showed that old age and high initial value of DLCO% were the risk factor for the decline of DLCO% (OR=1.105、1.078, P<0.05) .High smoking index was the risk factors for the decline of MEF75% (OR=1.016, P<0.05) . High stage and the increase of CAT score were the risk factors for the decline of MEF50% (OR=1.548, 1.162, P<0.05) . High initial value of MEF25% was the risk factor for the decline of MEF25% (OR=1.010, P<0.05) . Conclusion: The pulmonary function index of pneumoconiosis patients declined significantly in 3 years. The stage of pneumoconiosis, age, smoking index and degree of pulmonary function damage were related to the decline rate of pulmonary function.

Abstract
BACKGROUND This study investigated the relationship between thyroid diseases and the risk of breast cancer (BC). Clarifying this issue can help medical staff perform of early prevention, diagnosis and treatment for breast cancer patients. METHODS The meta-analysis combined data from cohort studies and case-control to obtain a comprehensive result of the relationship between thyroid diseases and risk of BC. We comprehensively searched PubMed, EMbase, Web of Science, and the Cochrane Library. The search period was from the establishment of the databases to August 2020. Literature was collected and screened individually by two reviewers. There was English language restriction on the search and unpublished literature was excluded. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the selected studies prior to data extraction. The data collected included country, author, year of publication, research type, and number of cases. In cases where the data and study heterogeneity permitted, meta-analyses were performed, and odd ratios (ORs) with corresponding 95% confidence intervals (CIs) were calculated. Data were analyzed using the STATA 15.1 software. RESULTS A total of 21 articles were included in this study. Hyperthyroidism, thyroid cancer, thyroglobulin antibody (TGAb) levels, and thyroid microsomal antibody (TPOAb) levels were all significantly associated with an increased risk of BC, while hypothyroidism was associated with a reduced risk of BC. CONCLUSIONS This study demonstrated that hyperthyroidism, autoimmune thyroiditis (AITD), and thyroid cancer are significantly associated with an increased risk of BC, while hypothyroidism is associated with a reduced risk of BC.

Abstract
AIM To explore the applicability of diffusion-tensor imaging (DTI) sequence quantitative parameters in differentiating uterine sarcoma (USr) from degenerative uterine fibroids (DUF). MATERIALS AND METHODS Fourteen cases of USr and 30 cases of DUF were analysed retrospectively. The diffusion-weighted imaging (DWI) and DTI images were analysed by two observers using Functool software on a ADW4.6 workstation. The images were post-processed to generate an apparent diffusion coefficient (ADC) map of DWI, ADC map of DTI (ADCT map), and fractional anisotropy (FA) map. Three regions of interest (ROI) were selected from the ADC, ADCT, and FA maps to obtain the ADC, ADCT, and FA values. The receiver operating characteristic (ROC) curves of all parameters were used to analyse and compare the diagnostic value of USr and DUF. RESULTS The ADC value, ADCT value, and FA value of USr (1.190 ± 0.262 × 10-3mm2/s, 1.165 ± 0.270 × 10-9mm2/s, 0.168 ± 0.063) were significantly lower compared to the values for DUF (1.525 ± 0.314 × 10-3mm2/s, 1.650 ± 0.332 × 10-9mm2/s, 0.254 ± 0.111; all p<0.001). The diagnostic threshold values for USr were: ADC ≤1.290 × 10-3mm2/s, ADCT ≤1.322 × 10-9mm2/s and FA ≤0.192. The corresponding sensitivities and specificities were 78.6%/90%, 96.7%/92.9%, and 86.7%/85.7%, respectively. The areas under the curve (AUC) were 0.875, 0.974, and 0.831, respectively. CONCLUSIONS DTI quantitative parameters can be used to differentiate USr from DUF. The ADCT value had the highest diagnostic efficacy.

Abstract
We report a study of the anharmonic lattice dynamics in low lattice thermal conductivity (κ_{l}) material AgCrSe_{2} by many-body perturbation theory. We demonstrate surprisingly giant four-phonon scattering exclusive for the heat-carrying transverse acoustic phonons due to large quartic anharmonicity and nondispersive phonon band structure, which lead to four-phonon Fermi resonance and breaks the classical τ^{-1}∼ω^{m}T^{n} relation for phonon-phonon interactions. This strong resonant scattering extends over the Brillouin zone and substantially suppresses the thermal transport, even down to a low temperature of 100 K. The present results provide fundamental insights into the four-phonon resonant dynamics in the low-κ_{l} system with flat phonon dispersions, i.e., cuprous halides and skutterudites.

Abstract
OBJECTIVES Coronavirus disease 2019 (COVID-19) is a major public health emergency. It poses a grave threat to human life and health. The purpose of the study is to investigate the chest CT findings and progression of the disease observed in COVID-19 patients. METHODS Forty-nine confirmed cases of adult COVID-19 patients with common type, severe and critically severe type were included in this retrospective single-center study. The thin-section chest CT features and progress of the disease were evaluated. The clinical and chest imaging findings of COVID-19 patients with different severity types were compared. The CT severity score and MuLBSTA score (a prediction of mortality risk) were calculated in those patients. RESULTS Among the 49 patients, 35 patients (71%) were common type and 14 patients (28%) were severe and critically severe type. Nearly all patients (98%) had pure ground-glass opacities (GGO) in CT imaging. Of the severe and critically severe type patients, 86% exhibited GGO with consolidation, in comparison with 54% of the patients with common type. Fibrosis presented in 79% of the severe and critically severe type patients and 43% of the common type patients. The severe and critically severe type patients were significantly more prone to experience five-lobe involvement compared to the common type patients (p = 0.002). The severe and critically severe type patients also had higher CT severity and MuLBSTA scores than the common type patients (5.43 ± 2.38 vs 3.37 ± 2.40, p < 0.001;and 10.21 ± 3.83 vs 4.63 ± 3.43, p < 0.001, respectively). MuLBSTA score was positively correlated with admittance to the intensive care unit (p = 0.005, r = 0.351). Nineteen patients underwent three times CT scan. The interval between first and second CT scan was 4[4,8] days, second and third was 3[2,4] days. There were greater improvements in the third CT follow-up findings compared to the second (p = 0.002). CONCLUSIONS The severe and critically severe type patients often experienced more severe lung lesions, including GGO with consolidation. The CT severity score and MuLBSTA score may be helpful for the assessment of COVID-19 severity and progression. ADVANCES IN KNOWLEDGE Chest CT has the value of evaluated radiographical features of COVID-19 and allow for dynamic observation of the disease progression. Considering coagulation disorder of COVID-19, MuLBSTA score may need to be updated to increase new understanding of COVID-19.

Abstract
Abstract
Background
Obstructive sleep apnea (OSA), the most common upper-airway disease, is closely associated with cardiovascular risk. However, the early detection of OSA is challenging, relying on polysomnography (PSG) or portable monitor (PM) in hospitals. A novel technology, photoplethysmography (PPG), has been developed for OSA screening. But there has been limited validation of PPG-based smart devices compared to PSG or PM.
Objective
This study aimed to investigate the feasibility and verify the validity of PPG-based smart devices in the detection of OSA in real-world settings.
Methods
A total of 119 consecutive outpatients, were recruited from the Chinese PLA General Hospital from Sep 29 to Nov 10, 2019. Participants were simultaneously tested with a smart watch, and PSG or PM for a whole night sleep.
Results
In all, 102 patients (48.5±13.7 years old, female 23.5%) were into the final analysis after excluding 17 patients with poor quality of PPG signals. Among them, 83 patients (81.3%) were diagnosed with OSA. Compared to PM, the corresponding accuracy, sensitivity and specificity of PPG-based smart device in predicting moderate to severe OSA patients ( Apnea Hypopnea Index, AHI ≥15) were 87.9% (95% Confidential Interval, CI: 78.8%–94.1%), 89.7% (95% CI: 75.8%–97.1%) and 86.0% (95% CI: 72.1%–94.7%), respectively. Compared to PSG, the accuracy, sensitivity and specificity in predicting all the sleep apnea patients (AHI ≥5) were 81.1% (95% CI: 72.1%–88.2%), 76.5% (95% CI: 50.1%–93.2%) and 100% (95% CI: 29.2%–100%), respectively. Moreover, for moderate to severe OSA patients (AHI ≥15), the predictive ability of PPG-based smart device in OSA was of no significant difference compared to PM (P=0.75) or PSG (P=0.52).
Conclusions
The PPG-based smart device demonstrated good performance in detecting OSA. Nevertheless, it requires further validation in a large-scale population on screening OSA.

Abstract
PURPOSE Our study aimed to comprehensively explore efficient prognostic indicators in idiopathic dilated cardiomyopathy (IDCM) patients with reduced left ventricular ejection fraction (LVEF<40%). BACKGROUND Prognostic value of cardiac magnetic resonance(CMR) parameters for IDCM have been inconsistent. METHODS 126 IDCM patients with reduced LVEF (<40%) were retrospectively enrolled. Cardiac function parameters, myocardial strain indices and myocardial fibrosis were evaluated. Laboratory data also were analyzed. The endpoint was a combination of major adverse cardiac events (MACEs), including cardiac death, heart transplantation, and rehospitalization. Prognostic value was evaluated by the Kaplan-Meier method and Cox regression. RESULTS During a median follow-up of 31 months, 44 patients experienced MACEs, including 9 deaths, 1 heart transplantation, and 34 rehospitalizations due to heart failure. Univariate and multivariate Cox analyses showed that cardiac function and myocardial strain indexes were not associated with the prognosis of IDCM (all p>0.05). NT-proBNP (HR 1.5, 95%CI: 1.053 to 2.137), Late‑gadolinium enhancement(LGE) mass (HR 1.022, 95%CI: 1.005 to 1.038), and LGE mass/left ventricle mass were significant predictors (HR 1.027, 95%CI: 1.007 to 1.046) for MACEs, all p < 0.05. Besides, poorest prognosis was observed in IDCM patients with positive LGE combined with NT-proBNP (log-rank = 27.261, p ≤ 0.001). CONCLUSION NT-proBNP and extent of LGE were reliable predictors in IDCM patients with reduced LVEF. Additionally, presence of LGE combined with NT-proBNP showed the strongest prognostic value in IDCM with reduced LVEF. Myocardial strain parameters seemed to have no prognostic value in IDCM patients with reduced LVEF.

Abstract
Background Increasing studies demonstrated that the cardiac involvements are related to coronavirus disease 2019 (COVID-19). Thus, we investigated the clinical characteristics of patients with COVID-19 and further determined the risk factors for cardiac involvement in them. Methods and Results We analyzed data from 102 consecutive laboratory-confirmed and hospitalized patients with COVID-19 (52 women aged 19-87 years). Epidemiologic and demographic characteristics, clinical features, routine laboratory tests (including cardiac injury biomarkers), echocardiography, electrocardiography, chest imaging findings, management methods, and clinical outcomes were collected. Patients were divided into acute cardiac injury, with and without cardiac marker abnormities groups according to different level of cardiac markers. In this research, cardiac involvement was found in 72 of the 102 (70.6%) patients: tachycardia (n=20), electrocardiography abnormalities (n=23), echocardiography abnormalities (n=59), elevated myocardial enzymes (n=55), and acute cardiac injury (n=9). Eight patients with acute cardiac injury were aged >60 years; seven of them had ≥2 underlying comorbidities (hypertension, diabetes mellitus, cardiovascular diseases, chronic obstructive pulmonary disease, and chronic kidney disease). Novel coronavirus pneumonia was much more severe in the patients with acute cardiac injury than in patients with nondefinite acute cardiac injury (P<0.001). Multivariate analyses showed that CRP (C-reactive protein) levels, old age, novel coronavirus pneumonia severity, and underlying comorbidities were the risk factors for cardiac abnormalities in patients with COVID-19. Conclusions Cardiac involvements are common in patients with COVID-19. Elevated CRP levels, old age, underlying comorbidities, and novel coronavirus pneumonia severity are the main risk factors for cardiac involvement in patients with COVID-19. More attention should be given to cardiovascular protection during COVID-19 treatment for mortality reduction. Registration URL: https://www.chictr.org; Unique identifier: ChiCTR2000029955.

Abstract
Background Randomized controlled trials (RCTs) provide the highest level of evidence and are likely to influence clinical decision-making. This study evaluated the reporting quality of RCT abstracts on drug therapy of periodontal disease and assessed the associated factors.
Material and Methods The Pubmed database was searched for periodontal RCTs published in Science Citation Indexed (SCI) dental journals from 2010/01/01 to 2019/07/17. Information was extracted from the abstracts according to a modified Consolidated Standards of Reporting Trials (CONSORT) guideline checklist. The data was analyzed using descriptive statistical analysis and the statistical associations were examined using the linear regression analysis (P <0.05).
Results This study retrieved 1715 articles and 249 of them were finally included. The average overall CONSORT score was 15.6 ± 3.4, which represented 40.9% (±0.6) of CONSORT criteria filling. The reporting rate of some items (trial design, numbers analyzed, confidence intervals, intention-to-treat analysis or per-protocol analysis, harms, registration) was less than 30%. The adequate reporting rate of some items (participants, randomization, numbers analyzed, confidence intervals, intention-to-treat analysis or per protocol analysis) was no more than 4%. None of the abstracts reported funding. According to the multivariable linear regression results, number of authors (P=0.030), word count (P <0.001), continent (P=0.003), structured format (P <0.001), type of periodontal disease (P <0.001) and international collaboration (P=0.023) have a significant association with reporting quality.
Conclusions The quality of RCT abstracts on drug therapy of periodontal disease in SCI dental journals remained suboptimal. More efforts should be made to improve RCT abstracts reporting quality. Key words:Abstracts, RCT, drug therapy, periodontal disease, CONSORT, reporting quality assessment.

Abstract
OBJECTIVE To compare the efficacy and safety of iodine-125 seed interstitial brachytherapy and local chemotherapy perfusion in treatment of advanced pancreatic cancer. METHODS The present open prospective randomized control study included a total of 165 cases of advanced pancreatic cancer patients who were admitted in our hospital during December 2016 to April 2019. All patients were randomized into two groups with 84 cases in iodine-125 group and 81 cases in chemotherapy perfusion group. Basic clinical characteristics and demographic data were collected. The main outcome was the tumor efficiency. The pain condition was measured by visual analogue scale (VAS) and the Karnofsky score was also measured at different time points, before the treatment, 1 d, 7 d, 14 d, 1 mon, 2 mon and 3 mon after treatment. Serum levels of CEA, CA19-9 and CA50 were measured by immunochemiluminescence. The overall survival was analyzed by K-M curve. RESULTS The ratio of partial remission patients was significantly higher, and the ratio of stable disease (SD)+progressive disease patients was also remarkably lower in iodine-125 group than the chemotherapy perfusion group. The mean VAS scores decreased markedly after treatment and were significantly lower and the mean Karnofsky scores were remarkably higher in iodine-125 group than the chemotherapy perfusion group. The levels of CA19-9 and CA50 were remarkably lower in iodine-125 group, however no significant difference was found for CEA. The survival analysis by K-M curve showed the iodine-125 patients had longer overall survival time than the chemotherapy perfusion group. No infection, pancreatic fistula, biliary fistula, intestinal fistula, gastrointestinal obstruction or radiation enteritis was found in both groups. CONCLUSION Iodine-125 seed interstitial brachytherapy could achieve better efficacy with no increased side complications than chemotherapy perfusion in advanced pancreatic cancer.

Abstract
Abstract
Background: Cancer patients are regarded as highly vulnerable group in the current SARS-CoV-2/COVID-19 pandemic. Up to date, the clinical characteristics of cancer patients with COVID-19 are largely unknown.
Patients and methods: In this retrospective cohort study, we collected and analyzed data of the cancer patients with y confirmed COVID-19 infection from three designated hospitals in Wuhan, China from Jan 13, 2020, to Feb 26, 2020. Univariate and multivariate analyses were performed to assess the risk factors associated with severe events defined as a condition that admission to an intensive care unit, the use of mechanical ventilation, or death. We also followed 124 cancer patients with immune checkpoint inhibitors (ICI) and their families for their infection rate and clinical outcome.
Results: Twenty-eight COVID-19 infected cancer patients were included with median age of 65.0 years (IQR:56.0-70.0) and male gender of 60.7% (17/28). Amount of these 28 patients, 7 (25%) had lung cancer, and 8 (28.6%) were considered to be infected via hospital-associated transmission. Fifteen (53.6%) patients had severe events with the mortality rate of 28.6%. The last anti-tumor treatment within 14 days from the diagnoses of COVID significant increased risk of developing severe events (HR=4.079, 95%CI 1.086-15.322, P=0.037). The common chest CT findings were ground-glass opacity (21, 75.0%) and patchy consolidation (13, 46.3%). The patchy consolidation on CT had a higher risk for developing severe events (HR=5.438, 95%CI 1.498-19.748, P=0.010). There was only one patient (1/124, 0.8%) who have been on ICI treatment for his metastatic HCC confirmed with COVID infection, and with mild clinic presentation and a short hospital course.
Conclusions: Cancer patients showed aggressive presentation and poor outcomes with the COVID-19 infection. It is recommended that vigorous screening for COVID-19 infection should be performed for cancer patients with anti-tumor. From our limited data, there is no evidence to suggest difference in cancer patients on ICI treatment.

Abstract
Background: Despite an increase in the familiarity of the medical community with the epidemiological and clinical characteristics of coronavirus disease 2019 (COVID-19), there is presently a lack of rapid and effective risk stratification indicators to predict the poor clinical outcomes of COVID-19 especially in severe patients. Methods: In this retrospective single-center study, we included 117 cases confirmed with COVID-19. The clinical, laboratory, and imaging features were collected and analyzed during admission. The Multi-lobular infiltration, hypo-Lymphocytosis, Bacterial coinfection, Smoking history, hyper-Tension and Age (MuLBSTA) Score and Confusion, Urea, Respiratory rate, Blood pressure, Age 65 (CURB65) score were used to assess the death and intensive care unit (ICU) risks in all patients. Results: Among of all 117 hospitalized patients, 21 (17.9%) patients were admitted to the ICU care, and 5 (4.3%) patients were died. The median hospital stay was 12 (10–15) days. There were 18 patients with MuLBSTA score ≥ 12 points and were all of severe type. In severe type, ICU care and death patients, the proportion with MuLBSTA ≥ 12 points were greater than that of CURB65 score ≥ 3 points (severe type patients, 50 vs. 27.8%; ICU care, 61.9 vs. 19.0%; death, 100 vs. 40%). For the MuLBSTA score, the ROC curve showed good efficiency of diagnosis death (area under the curve [AUC], 0.956; cutoff value, 12; specificity, 89.5%; sensitivity, 100%) and ICU care (AUC, 0.875; cutoff value, 11; specificity, 91.7%; sensitivity, 71.4%). The K–M survival analysis showed that patients with MuLBSTA score ≥ 12 had higher risk of ICU (log-rank, P = 0.001) and high risk of death (log-rank, P = 0.000). Conclusions: The MuLBSTA score is valuable for risk stratification and could effectively screen high-risk patients at admission. The higher score at admission have higher risk of ICU care and death in patients infected with COVID.

Abstract
Background The outbreak of Corona Virus Disease-2019 (COVID-19) has posed unprecedented pressure and threats to healthcare workers in Wuhan and the entire country. Aims To assess the effect of the COVID-19 outbreak on the sleep quality of healthcare workers in a children’s healthcare centre in Wuhan. Methods A cross-sectional, anonymized, self-reported questionnaire survey was conducted at the Children’s Healthcare Centre of Renmin Hospital, Wuhan University, Wuhan, China. The questionnaire consisted of three parts, including socio-demographic characteristics and COVID-19 epidemic-related factors, the Pittsburgh sleep quality index (PSQI), and Zung’s self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Results In total, 47 out of 123 (38%) participants with PSQI scores > 7 were identified as having sleep disturbance. A logistic regression analysis showed that sleep disturbance was independently associated with being an only child (adjusted odds ratio (OR) and 95% confidence interval (CI) 3.40 (1.21–9.57), P < 0.05), exposure to COVID-19 patients (adjusted OR and 95% CI 2.97 (1.08–8.18), P < 0.05) and depression (adjusted OR and 95% CI 2.83 (1.10–7.27), P < 0.05). Conclusions We observed that, during the outbreak of COVID-19, sleep disturbance was highly prevalent among paediatric healthcare workers, and sleep disturbance was independently associated with being an only child, exposure to COVID-19 patients and depression. Therefore, more mental health services are required for front-line paediatric healthcare workers in Wuhan.

Abstract
Recurrence and diffuse infiltration challenge traditional therapeutic strategies for malignant glioma. Immunotherapy appears to be a promising approach to obtain long-term survival. Dendritic cells (DCs), the most specialized and potent antigen-presenting cells (APCs), play an important part in initiating and amplifying both the innate and adaptive immune responses against cancer cells. However, cancer cells can escape from immune surveillance by inhibiting maturation of DCs. Until the present, molecular mechanisms of maturation inhibition of DCs in the tumor microenvironment (TME) have not been fully revealed. Our study showed that pretreatment with tumor-conditioned medium (TCM) collected from supernatant of primary glioma cells significantly suppressed the maturation of DCs. TCM pretreatment significantly changed the morphology of DCs, TCM decreased the expression levels of CD80, CD83, CD86 and interleukin (IL)-12p70, while it increased the expression levels of IL-10, transforming growth factor (TGF)-β and IL-6. RNA-Seq showed that TCM pretreatment significantly increased the gene expression level of suppressor of cytokine signaling 1 (SOCS1) in DCs. suppressor of cytokine signaling 1 (SOCS1) knock-down significantly antagonized the maturation inhibition of DCs by TCM, which was demonstrated by the restoration of maturation markers. TCM pretreatment also significantly suppressed T cell viability and T helper type 1 (Th1) response, and SOCS1 knock-down significantly antagonized this suppressive effect. Further, TCM pretreatment significantly suppressed p65 nuclear translocation and transcriptional activity in DCs, and SOCS1 knock-down significantly attenuated this suppressive effect. In conclusion, our research demonstrates that TCM up-regulate SOCS1 to suppress the maturation of DCs via the nuclear factor-kappa signaling pathway.
