Abstract
OBJECTIVE The acceleration of population aging has brought an unprecedented impact on China's health system. This study is designed to examine the association between depressive symptoms and activity of daily living disability among the elderly in China. STUDY DESIGN This is a cross-sectional study. METHODS Data were drawn from the China Health and Retirement Longitudinal Study (CHARLS). The 10-item Center for Epidemiologic Studies-Depression (CES-D) scale was used to access depressive symptoms, and physical function was assessed by the Activity of Daily Living (ADL) scale. Multivariate logistic regression was used to assess the association between depressive symptoms and ADL among the elderly. RESULTS Based on a sample of 5863 elderly people over 60 years old, our results showed that 1999 elderly people are with depressive symptoms, accounting for 34.1%. The mean score of ADL among the elderly with depressive symptoms (20.65 ± 7.14) was much higher than that in those without depressive symptoms (17.40 ± 4.87). After controlling potential confounders, multivariate logistic regression showed that ADL and its specific domains including personal care, transfer, medical care, household, and managing money were associated with depressive symptoms. CONCLUSION This cross-sectional study provides evidence of the association between depressive symptoms and ADL disability among the Chinese elderly. As a result, prevention or reduction of ADL disability may have a positive effect on the medical care of the elderly with depressive symptoms.

Abstract
Objective: To investigate the molecular epidemiology of norovirus associated with pediatric acute gastroenteritis in Beijing under the Working Mechanism for Joint Prevention and Control of the Epidemic in 2020. Methods: This was a retrospective, repeated cross-sectional study. Fecal or vomit samples (1 213 cases) were collected from children visited the Capital Institute of Pediatrics Affiliated Children's Hospital for acute gastroenteritis from January 1 to December 31, 2020. First, real-time reverse PCR (RT-PCR) was used to screen the samples for norovirus, and then RdRp gene and capsid gene VP1 of norovirus-positive samples were amplified by conventional RT-PCR for genotyping based on the nucleotide sequence. The χ2 test was used to compare the positive rates and genotypes of norovirus among different specimen types, genders of children, and different age groups. Results: Among the 1 213 samples were collected, 215 samples were positive for norovirus, with a positivity rate of 17.7% for the whole year. The peak of norovirus infection observed mainly in the cold seasons, as the positive rates were 28.6% (18/63), 26.2% (16/61), 22.8% (77/338) and 17.1% (89/520) in January, October, November and December, respectively. The positive rate of norovirus in fecal sample was significantly higher than that in vomit sample (χ2 = 9.692, P<0.01). There was no significant difference between genders (χ2=0.041, P>0.05), but significant difference was found between age groups with the highest rate in the 6-48 months group (χ²=103.112, P<0.01). Three genogroups (GⅠ, GⅡ and GⅨ) of the circulating virus were detected by G-gene typing, and GⅡgenogroup was predominant, accounting for 98.5% (196/199). Among the GⅡ positive samples, genotype GⅡ.4 Sydney (55.1%, 108/196) was the most common, followed by GⅡ.2 (29.6%, 58/196), while the GⅡ.3 norovirus (10.2%, 20/196) which was common in previous years was not as much as before. Based on the P-type, GⅡ.P16 was predominant (61.5%, 96/156), followed by GII.P31 (19.9%, 31/156). The dual genotyping revealed that GⅡ.4 Sydney [P16] (36.4%, 56/154) and GⅡ.2 [P16] (24.7%, 38/154) were predominant. Conclusion: The prevalence of norovirus in children in 2020 in Beijing is not much different from those of the previous years, but the genotypes composition has changed significantly, and there are multiple genotypes circulating simultaneously.

Abstract
The activation of immune pathways is triggered by the recognition of pathogens by pattern recognition receptors (PRRs). Gram-negative bacteria-binding proteins (GNBPs)/β-1,3-glucan recognition proteins (βGRPs) are a conserved family of PRRs in insects. Two GNBPs are predicted in the genome database of pea aphids; however, little is known about their functions in the aphid immune system. Here, we show that pea aphid GNBPs possess domain architectures and sequence features distinct from those of typical GNBPs/βGRPs and that their expression is induced by bacterial infection. Knockdown of their expression by dsRNA resulted in lower phenoloxidase activity, higher bacterial loads and higher mortality in aphids after infection. Our data suggest that these two atypical GNBPs are involved in the antibacterial response in the pea aphid, likely acting as PRRs in the prophenoloxidase pathway.

Abstract
BACKGROUND Long- and short-term ultraviolet (UV) exposure have distinct biological effects on human fibroblasts. OBJECTIVES This study aimed to elucidate the underlying mechanisms of the biological effects of UV exposure on human skin fibroblasts. METHOD We subjected human skin fibroblast cells with or without AQP3, DEDD, or Beclin1 manipulation to UVA treatment and evaluated autophagy and senescence/aging in them. RESULTS Short-term UVA irradiation induced autophagy and upregulated AQP3 but not senescence, whereas long-term UVA irradiation inhibited autophagy, AQP3, and senescence/aging in vitro and in vivo. Silencing AQP3 abolished short-term UVA irradiation-induced autophagy and led to cellular senescence, whereas AQP3 overexpression partially rescued the senescence and autophagy inhibition induced by long-term UVA exposure in vitro. Mechanistically, the transcription factor JUN was found to bind to the AQP3 promoter to activate its transcription following short-term UVA exposure. Subsequently, AQP3 interacted with DEDD to induce its ubiquitination-mediated degradation and promote autophagy, and bound to Beclin1 to directly activate autophagy. Finally, autophagy induced by AQP3 overexpression robustly prevented UVA-induced senescence/aging in vitro and in vivo. CONCLUSIONS Thus, our study indicates that AQP3 controls skin fibroblasts photoaging by regulating autophagy and represents a potential target for future interventions against skin aging.

Abstract
OBJECTIVES To evaluate risk factors and prognosis of lung metastases in patients with renal cell carcinoma (RCC) based on the Surveillance, Epidemiology, and End Results (SEER) database. METHODS 56,617 patients with RCC were selected from the SEER database. Based on univariate and multivariate logistic regression, the risk factors for developing lung metastases were derived. 2906 patients were initially diagnosed with lung metastases, and then were used to research the prognostic factors. Multivariable Cox regression analyses were performed for the prediction of cancer-specific mortality. RESULTS In total, 2906 RCC patients were initially diagnosed with lung metastases. The prevalence of lung metastases in RCC was approximately 5% with poor survival. Aging, male, other race (American Indian/AK native, Asian Pacific islander) uninsured status, bilateral tumor, collecting duct, higher T stage, local lymph node metastases, higher tumor grade, and evidence of other distant metastases were significantly associated with developing lung metastases at diagnosis. Age >70 years-old, black, female, bilateral tumor, T4 stage, higher tumor grade, local lymph node metastases, collecting duct, and evidence of bone, liver, or brain metastases were related to higher risk of mortality. Blacks and female have lower odds of developing lung metastases at the time of diagnosis both in crude and adjusted logistic regression. Meanwhile, blacks and female showed higher risk of mortality compared with whites and male in Cox regression analyses. CONCLUSION Several factors related to the development and prognosis of lung metastases were revealed, especially black people and female gender have lower risk of developing lung metastatic RCC at initial diagnosis but have higher risk of mortality. These may provide preventive guidelines for the screening and treatment of lung metastases in patients with renal cell carcinoma.

Abstract
OBJECTIVE To investigate whether TRIM59 regulates invasion and metastasis of nasopharyngeal carcinoma cells by targeting PPM1B. METHOD We analyzed the expression of TRIM59 in nasopharyngeal carcinoma tissues based on data from TCGA database and detected the expressions of TRIM59 and PPM1B in nasopharyngeal carcinoma and adjacent tissues using Western blotting. We also detected the expressions of TRIM59 and PPM1B at both the mRNA and protein levels in nasopharyngeal carcinoma cell lines using RT-PCR and Western blotting. Stable cell lines with TRIM59 overexpression or knockdown were established in HNE1 cells, in which the targeting relationship between TRIM59 and PPM1B was analyzed using Western blotting and a luciferase reporter gene assay. Transwell chamber assay was used to assess changes in the invasion and migration abilities of HNE1 cells with TRIM59 overexpression or knockdown. RESULTS Analysis based on TCGA database showed that TRIM59 expression was significantly higher in nasopharyngeal carcinoma tissues than in adjacent tissues (P=0.006); the expression of TRIM59 increased (P=0.01) and PPM1B expression decreased significantly (P=0.03) in nasopharyngeal carcinoma tissues. Compared with HNEpC cells, HNE1 cells expressed a significantly higher level of TRIM59 (P=0.04) but a lower level of PPM1B (P=0.01). Luciferase reporter gene assay indicated that PPM1B was a downstream target gene of TRIM59 and its expression was negatively correlated with TRIM59 expression (P=0.01). In HNE1 cells, TRIM59 overexpression significantly promoted cell invasion (P=0.01) and migration (P=0.02) while TRIM59 knockdown obviously suppressed cell invasion (P=0.01) and migration (P=0.01). TRIM59 knockdown with simultaneous PPM1B overexpression more strongly inhibited invasion (P=0.02) and migration (P=0.01) of HNE1 cells as compared with TRIM59 knockdown alone. CONCLUSION TRIM59 regulates invasion and migration of nasopharyngeal carcinoma cells through targeted modulation of PPM1B.

Abstract
Telomerase reverse transcriptase (TERT) vectors were transfected into bone marrow mesen- chymal stem cells (BMSCs) which were then cultured and selected to establish TERT-BMSC cell lines whilst sequencing BMSCs and TERT-BMSCs via transcriptome in this study to explore their regulatory mechanism and effect on osteogenic differentiation after TERT ectopic expres- sion in sheep BMSCs. After sequencing and analysing differential genes, PI3K/Akt signalling pathway related to osteogenic differentiation was investigated. Western blot was used before and after applying the PI3K/Akt signalling pathway inhibitor LY294002 to detect protein expression levels of AKT and p-AKT. On the twenty-first day of osteogenic differentiation, RT-qPCR and Western blot were used to detect mRNA and protein expression levels of RUNX2 and OPN and alizarin red staining was utilised to analyse calcium salt deposition. Results showed that pro- tein expression levels of AKT and p-AKT were significantly up-regulated, mRNA and protein expression levels of RUNX2 and OPN increased and calcium salt deposition increased after ectopic expression of TERT. After applying LY294002, the protein expression of AKT and p-AKT was down-regulated, mRNA and protein expression levels of RUNX2 and OPN were reduced and calcium salt deposition was reduced. These results confirmed the stable integration and expression of the exogenous TERT gene in BMSCs to promote the differentiation of BMSC osteoblasts, which may be mediated by the PI3K/Akt signalling pathway.

Abstract
Background The aim of this study was to investigate the application of remote learning and virtual microscopy in oral histopathology teaching, a unique experience in China. The oral histopathology teaching in Nanjing Medical University has been extraordinary. Material and Methods 98 third-year dental students of Grade 2016 took oral histopathology theoretical course face-to-face in 2019 (Traditional group). The 94 participants of Grade 2017 took online oral histopathology course using digital methods(E-Learning platform and Virtual Simulation Experiment Teaching Center for Dentistry) in 2020. During the practical laboratory sessions, the students in both Traditional group and Online group observed the same glass slides for morphological learning. A questionnaire survey explored students' attitudes towards the remote online learning. Results: The mean Theory test scores of the Online group (80.93±12.15) were significantly higher than those of the Traditional group (73.65±8.46) (P < 0.01). The mean total scores of the Online group (82.94±10.76) were significantly higher than those of the Traditional group (77.25±7.55) (P < 0.01). The percentage of high total test score (test score > 85) of the Online group (54%) was also significantly higher than that of the Traditional group (15%) (P< 0.01). Furthermore, both remote learning and virtual microscopy courses were well accepted by students according to the questionnaire. Conclusions This study found that remote learning and virtual technology have a positive impact on oral histopathology. The findings reveal that the application of remote online learning has enhanced oral histopathology teaching in China.

Abstract
1. Bromodomain-containing protein 2 (BRD2) is an important member of the BET protein family, which can specifically bind histone acetylated lysine to participate in gene transcriptional regulation, chromatin remodelling, cell proliferation and apoptosis. The following investigation of cellular proteins interacting with chBRD2 will be helpful in understanding the new functions of chBRD2 and the mechanism of NDV replication.2. The recombinant eukaryotic expression vector pEGFP-chBRD2 and empty vector pEGFP-C1 were transfected into DF-1 cells to overexpress GFP-chBRD2 and GFP, respectively. GO annotation, KEGG pathway, and protein-protein interaction network were used to analyse the cellular proteins interacting with chBRD2. In addition, one targeted protein was selected to verify its interaction with chBRD2 using fluorescent co-localisation and Co-IP.3. A total of 225 cellular proteins were identified that potentially interact with chBRD2. GO analysis showed that these play key roles in gene transcriptional regulation, cell cycle and development, immunity and viral infection. Further KEGG pathway analysis showed that these proteins were mainly involved in genetic information processing, immune system, cellular processes and translation. In addition, one targeted cellular protein chicken matrin 3 (chMATR3) was also identified as chBRD2 complex using both fluorescence co-localisation and Co-IP analysis.4. This study presents the interactome data of chBRD2 protein in DF-1 cells, which provides new information to understand the functions of chBRD2 and new targets for further investigating the replication and pathogenesis of NDV.

Abstract
OBJECTIVE Long non-coding RNA (lncRNA) was frequently abnormally expressed in cancers. LINC00641 was reported to play crucial roles in regulating tumor progression. However, its role in prostate cancer (PCa) has not been fully explored. PATIENTS AND METHODS In this work, proliferation, invasion and apoptosis assays were performed to detect the biological roles of LINC00641 in PCa. Bioinformatic analyses, Luciferase activity reporter assay, and rescue experiments were performed to investigate the potential mechanisms of LINC00641 in PCa. Expression levels of LINC00641, microRNA-365a-3p (miR-365a-3p), and vestigial like family member 4 (VGLL4) in PCa tissues and normal tissues were analyzed at ENCORI. RESULTS We found LINC00641 and VGLL4 was reduced, while miR-365a-3p was elevated expression in PCa tissues compared with normal tissues. LINC00641 overexpression inhibited growth and invasion abilities of PCa cells in vitro. Functional assays revealed that miR-365a-3p/VGLL4 pair was the downstream targets of LINC00641. CONCLUSIONS The findings of our work provided evidence that LINC00641 serves as a tumor suppressive lncRNA in PCa by regulating miR-365a-3p/VGLL4 axis.

Abstract
UNLABELLED We evaluated the associations of serum insulin-like growth factor-1 (IGF-1) with bone mineral density (BMD) and risk of fractures in Chinese patients with type 2 diabetes (T2D). We found positive associations between IGF-I and BMD and negative associations between IGF-I and all three modified 10-year probabilities of MOFs and HFs in men, but not in women. INTRODUCTION The objective was to investigate the associations of serum insulin-like growth factor-1 (IGF-1) with bone mineral density (BMD) and risk of fractures in Chinese patients with type 2 diabetes (T2D) in each gender. METHODS This was a cross-sectional, retrospective study that included men over 50 years and postmenopausal women with T2D without medical conditions or medications known to significantly affect BMD or serum IGF-I levels. Data of IGF-1, bone metabolism markers, lumbar spine (LS), femoral neck (FN), and total hip (TH) BMD were obtained; 10-year probability of major osteoporotic fractures (MOFs) and hip fractures (HFs) was calculated and modified with rheumatoid arthritis, femoral neck T-score, and age. Correlations of IGF-1 levels with bone metabolism and risk of fractures were statistically analyzed in men and women, respectively. RESULTS A total of 391 patients, including 226 men and 165 women, were included. The age, serum fasting C-peptide, glycosylated hemoglobin (HbA1c), bone formation marker, and all three modified 10-year probabilities of MOFs and HFs were higher in women than those in men (all p < 0.05). The levels of 25 hydroxyvitamin D (25OHD), IGF-1, and BMD were lower in women than those in men (all p < 0.05). In men, IGF-1 was positively correlated with FN and TH BMD (FN BMD: r = 0.267, p < 0.001; TH BMD: r = 0.235, p < 0.001) and negatively correlated with all three modified 10-year probabilities of MOFs (RA-modified MOFs: r = - 0.289, p < 0.001; age-modified MOFs: r = - 0.237, p < 0.001; FN T-score-modified MOFs: r = - 0.280, p < 0.001) and HFs (RA-modified HFs: r = - 0.291, p < 0.001; age-modified HFs: r = - 0.271, p < 0.001; FN T-score-modified HFs: r = - 0.270, p < 0.001), while no significant correlations were found between serum IGF-I and BMD and three modified 10-year probability in women. CONCLUSIONS According to this study, we found sex differences in the associations of serum IGF-1 with BMD and risk of fractures in Chinese patients with T2D. These results suggested that increasing serum IGF-1 might be a clinical target for protecting fractures in T2D, especially in men.

Abstract
Background:The prognosis of anti-melanoma differentiation-associated gene 5 positive dermatomyositis (anti-MDA5+ DM) – associated interstitial lung disease (ILD) is poor and heterogeneity.Objectives:The aim of this study was to evaluate prognostic factors and to develop a simple and generally applicable bedside decision tree model for predicting outcomes in patients with anti-MDA5+ DM and to guide treatment.Methods:We analyzed data for 246 anti-MDA5+ DM patients from Myositis Study Group-Jiangsu, a multicenter cohort across eighteen tertiary hospitals in Jiangsu province, from March 2019 to October 2020. The primary end point was all-cause death, and the secondary end point was occurring of rapidly progressive-ILD (rp-ILD). We used a multivariable Cox proportional hazards model to identify the independent prognostic risk factors of death and rp-ILD respectively. A decision-tree prediction model was developed by using data from 10 hospital of southern region (n=163), with validation by using contemporaneous data from northern region (n=83).Results:To assess the risk of rp-ILD, we developed a combined risk score, the CROSS score, that included the following values and scores: C-reactive protein (≤8mg/L, 0; >8mg/L, 3), anti-Ro52 antibody (negative, 0; positive, 4), Sex (Female, 0; Male, 2) and Short course of disease (More than 3 months, 0; Less than 3 months, 2). The mortality risk was identified by the CAR score, including C-reactive protein (≤8mg/L, 0; >8mg/L, 1), Alanine Transaminase (≤50units/L, 0; >50units/L, 1) and rp-ILD (non-rpILD, 0; rp-ILD, 3). We divided patients into three risk groups according to the CROSS score: low, 0 to 3; medium, 4 to 7; and high 8-11. And then Use of a simple decision tree prediction model permitted stratification into three different outcome prediction groups. High-risk patients had significantly higher mortality rates than low- and medium-risk patients in both discovery and validation cohorts (p < 0.0001).Conclusion:The CROSS-CAR decision tree model is easy to evaluate the poor prognostic risk in MDA5+ DM patients during any follow-up period. Unnecessary lung examination, such as chest CT scan and arterial blood gas analysis was avoided in low- and medium- rpILD risk patients. The special ambulance, with red cross sign tagged on car in China, may help to screen the high risk patients and to guide further treatment.Disclosure of Interests:None declared

Abstract
Background:AS is a chronic inflammatory immune-mediated disease primarily affecting the sacroiliac joints and spine, with a prevalence of 0.2%–0.5% in the United States.1 Because radiographic features of the disease can take years to develop, diagnosis may be delayed by up to 10 years2, which can negatively affect patients’ function, ability to work, and overall quality of life.Objectives:To describe geographic variations in AS diagnostic prevalence and treatment in the United States.Methods:This study utilized the IBM® MarketScan® Administrative Claims Database from 2014–2019. Patients (pts) ≥18 years of age with AS, continuous medical and pharmacy enrollment during the calendar year, and complete geographic information during the study period were included. Pts were identified by having ≥1 claim with ICD-9-CM or ICD-10-CM codes for AS (720.0 or M45.x, respectively). Two AS diagnosis definitions were used; Definition 1 (D1): Pts with ≥1 claim for an AS diagnosis in the year by any provider and Definition 2 (D2): Pts with ≥2 claims for an AS diagnosis within 18 months by rheumatologists. Annual AS diagnostic prevalence rates were calculated for both groups; treatment was evaluated among pts with D2. Diagnosis and treatment rates were assessed from 2014–2019 at the national and state levels and reported for states where >20 pts received an AS diagnosis (D1 or D2) or respective treatment (D2). The effect of age, sex, race (surrogate for HLA-B27), and rheumatologist per capita on geographic variation was assessed.Results:The number of pts included per year ranged between 10,811–13,077 (D1) and 3,775–4,901 (D2). AS diagnostic prevalence increased over time for both groups, with the annual prevalence rate per 10,000 persons for D2 pts increasing from 2.5 in 2014 to 3.5 in 2019 (Table 1). The AS diagnostic prevalence by D2 in 2019 was highest for Idaho (13) and Colorado (6), and lowest for Michigan (2). The state variations in prevalence did not appear to be explained by age, sex, racial distribution, or rheumatologists per capita. The percentage of D2 pts receiving advanced therapies (all FDA-approved indicated biologic disease-modifying antirheumatic drugs [bDMARDs] for AS) were >70% and increased each year, whereas the use of conventional synthetic DMARDs (csDMARDs) decreased (Figure 1. next page). While opioid use decreased, 37% of D2 pts were prescribed such treatment in 2019. Percentage of D2 pts receiving advanced therapy in 2019 was highest (91) in Minnesota and South Carolina and lowest in Idaho (69) and Indiana (70). In 2019, the percentage of D2 pts using csDMARDs in 2019 was highest in Oklahoma (33) and lowest (16) in North Carolina and New York, while for opioids it was highest in Idaho (69) and lowest in Wisconsin (28).Conclusion:The prevalence of AS is increasing each year nationally, with significant variability observed across states that is not explained by differences in age, sex, race, or rheumatologists per capita. Among pts with confirmed AS diagnosis (D2), national rates of csDMARDs and opioids are decreasing although opioid use is still high, and high treatment rates exist for advanced therapies. Rates of all treatments also vary substantially across states. Observed variations may indicate the opportunity for further education that can be targeted based on regional need to improve diagnosis and treatment.References:[1]Reveille JD. Am J Med Sci. 2011. 2.

Abstract
The world including South Africa is faced with unprecedented environmental changes, which can be linked to climate-related disasters such as drought and extreme heat. Several studies have indicated that these changes are likely to accelerate in the future and cause an adverse impact on the environment. The Eastern Cape Province of South Africa, especially Amathole District Municipality (ADM), has recorded a high number of climate change-related disasters including prolonged drought conditions witnessed during the winter season of 2008, 2009, 2014 and 2015 among others. Consequently, this study aimed at exploring remote sensing information to assess and document drought occurrences in the ADM from 2007 to 2017. To accomplish the aim, the Normalized Difference Vegetation Index, Land Surface Temperature and Precipitation were utilised to access drought spatiotemporal variations. For the analysis, a total of 396 satellite imageries (MODIS and TRMM) were used. The results revealed that different correlations exist between the three variables. The significance of correlations differed from one season to another. Furthermore, it was revealed that the drought conditions in the district differed in the spatial distribution. The study accurately identified the drought episodes that occurred in the ADM in the years 2008, 2009, 2014, 2015 and 2016. The chosen methodology and variables proved to be suitable for analysing drought conditions offering space and temporal variation dimension, which is vital in monitoring drought events.

Abstract
Dryopteris crassirhizoma Nakai is a fern plant with important evolutionary and medicinal values. Herein, we assembled the complete chloroplast genome of D. crassirhizoma by next-generation sequencing technology. The complete chloroplast genome of D. crassirhizoma was 153,355 bp in length, and the GC content was 42.86%; the genome consisted of a pair of inverted repeats (IRs, 23,470 bp), a small single copy region (SSC, 21,570 bp) and a large single copy region (LSC, 84,854 bp). The genome contained 111 genes, namely, 73 protein-coding genes, 34 tRNA genes and four rRNA genes. The phylogenetic analysis suggested that both D. crassirhizoma and D. decipiens from Dryopteridaceae were most closely related to Lepisorus clathratus from Polypodiaceae.

Abstract
OBJECTIVES The aim of this study was to examine the association of household debt and depressive mood among Chinese adults and to evaluate whether the association varies across types of debt. STUDY DESIGN This is a secondary data analysis of a nationally representative survey. METHODS A prospective cohort study of participants was drawn from the China Family Panel Studies (CFPS). In total, 5135 participants had their depressive mood measured in the CFPS starting from 2014 to 2016 and had participated in the biennial survey. We used logistic regression models to identify predictors of depressive mood with debts, sociodemographic factors, health status factors and health behaviors factors. Adjusted for all measured covariates, we conducted an independent analysis for the experience of housing loans from formal institutions (HLFI), other loans from formal institutions (OLFI), housing loans from relatives and friends (HLRF) and other loans from relatives and friends (OLRF). RESULTS Multiple logistic regression analyses revealed that household debt was a significant risk factor for depressive mood (1.35; 95% confidence interval [CI], 1.19-1.54), after controlling for potential confounders. Independent analysis revealed that HLFI was not a significant predictor, while HLRF (1.26; 95% CI, 1.08-1.48), OLFI (1.45; 95% CI, 1.13-1.87) and OLRF (1.23; 95% CI, 1.02-1.47) remained significant risk factors. CONCLUSION OLFI, HLRF and OLRF were associated with depressive mood, while HLFI was not. To address the problem of individual depressive mood, its apparent association with household debt should be paid more attention.

Abstract
OBJECTIVES To evaluate risk factors and prognosis of lung metastases in patients with renal cell carcinoma (RCC) based on the Surveillance, Epidemiology, and End Results (SEER) database. METHODS 56, 617 patients with RCC were selected from the SEER database. Based on univariate and multivariate logistic regression, the risk factors for developing lung metastases were derived. 2, 906 patients were initially diagnosed with lung metastases, and then were used to research the prognostic factors. Multivariable Cox regression analyses were performed for the prediction of cancer-specific mortality. RESULTS In total, 2,906 RCC patients were initially diagnosed with lung metastases. The prevalence of lung metastases in RCC was approximately 5% with poor survival. Aging, male, other race (American Indian /AK native, Asian Pacific islander) uninsured status, bilateral tumor, collecting duct, higher T stage, local lymph node metastases, higher tumor grade, and evidence of other distant metastases were significantly associated with developing lung metastases at diagnosis. Age > 70 years-old, black, female, bilateral tumor, T4 stage, higher tumor grade, local lymph node metastases, collecting duct, and evidence of bone, liver, or brain metastases were related to higher risk of mortality. Blacks and female have lower odds of developing lung metastases at the time of diagnosis both in crude and adjusted logistic regression. Meanwhile, blacks and female showed higher risk of mortality compared with whites and male in Cox regression analyses. CONCLUSION Several factors related to the development and prognosis of lung metastases were revealed, especially black people and female gender have lower risk of developing lung metastatic RCC at initial diagnosis but have higher risk of mortality. These may provide preventive guidelines for the screening and treatment of lung metastases in patients with renal cell carcinoma.

Abstract
Linear and nonlinear quantitative structure-property relationship (QSPR) models were developed based on a dataset with 65 polymer-solvent combinations. Seven quantum chemical descriptors, dipole moment, hardness, chemical potential, electrophilicity index, total energy, HOMO and LUMO orbital energies, were calculated with density functional theory at the B3LYP/6-31 G(d) level for polymers and solvents. Considering the strong correlation between intrinsic viscosity and weight, size, shape as well as topological structure of polymers and solvents, topological descriptors were also applied in this work. Meanwhile, the most appropriate polymer structure representation was investigated by considering 1-5 monomeric repeating units. The molecular descriptors were first screened by using the genetic algorithms-multiple linear regression (GA-MLR), with coefficient of determinations (r2) of 0.78 and 0.83 for the training set and the prediction set, respectively. The support vector machine model (SVM) model based on the selected descriptors subset showed a r2 value of 0.95 for the training set and 0.93 for the prediction set. All statistical results suggest that the established QSPR models have good predictability. Furthermore, a new test set obtained from the literature was used for further validation. The r2 values were 0.81 for the MLR model and 0.90 for the SVM model.

Abstract
OBJECTIVE We compared demographic and clinic-pathological variables related to the number of surgeries for thyroid conditions or for cancer, morbidity, and fine needle aspiration (FNA) practices among Covid19 pandemic phases I, II, III and the same seasonal periods in 2019. METHODS The prospective database of the Division of Thyroid Surgery, China-Japan Union Hospital of Jilin University, Changchun, China was used for this study. Covid19 emergency levels were stratified according to the World Health Organization: phase I (January 25-February 25, 2020), phase II (February 26-March 19), phase III (March 20-April 20). RESULTS There were fewer outpatient FNAs and surgeries in 2020 than in 2019. There were no thyroid surgeries during phase I. There were also fewer surgeries for cancer with a significant reduction of advanced stage cancer treatments, mainly stage T1b N1a in phase II and T3bN1b in phase III. Operative times and postoperative stays were significantly shorter during the pandemic compared to our institutional baseline. In phase III, vocal cord paralysis (VCP) increased to 4.3% of our baseline numbers (P = 0.001). There were no cases of Covid19-related complications during the perioperative period. No patients required re-admission to the hospital. CONCLUSION The Covid19 outbreak reduced thyroid surgery patient volumes. The decrease of Covid19 emergency plans contributed to unexpected outcomes (reduction of early stage cancer treatment, decreased operative times and hospital stays, increased VCP rate).

Abstract
SETTING: China National Tuberculosis Programme, 2010-2017.OBJECTIVE: To describe the epidemiology of childhood (age < 15 years) TB, including treatment outcomes and risk factors for unfavourable outcomes and death.DESIGN: We used a cross-sectional design for the descriptive component and a cohort design for treatment outcomes and their risk factors (assessed using log binomial regression).RESULTS: Of 40 561 children, 77.7% (n = 31 529) were aged 10-14 years and 19.6% (n = 7931) were bacteriologically confirmed. Around 14% (n = 5827) belonged to migrant families (internal migration) and 4.0% (n = 1,642) were actively detected. Over 8 years, annual notification was consistently very low (<1%), and notification of bacteriologically confirmed TB decreased by half. Unfavourable outcomes were seen in 6% and deaths in 0.4%; there were no significant changes over the years. The independent predictors of unfavourable outcomes were active case finding and extrapulmonary TB. Children belonging to migrant family were more likely to die. Independent predictors of unfavourable outcomes as well as death were age < 5 years and previous treatment.CONCLUSION: China needs to address the issue of under-detection of childhood TB, especially in younger age groups. The risk factors identified require attention if China is to attain zero child TB deaths.

Abstract
Objective: To compare the clinical and prognostic characteristics of ovarian endometrioid carcinoma (OEC) patients with synchronous endometrial lesions and patients with pure OEC. Methods: A retrospective review of the medical records of patients received initial treatment and a postoperative pathological diagnosis of OEC at Peking University People's Hospital between August 1998 and December 2017 were performed. According to the inclusion criteria, a total of 56 patients with OEC were included in the study, including 13 patients concurrent with simultaneous endometrial lesions (Group A) and 43 patients with pure OEC (Group B). Results: Patients with synchronous endometrial lesions accounted for 23% (13/56). Mean age of Group A at diagnosis was (44.9±8.3) years old, 2/13 of patients were postmenopausal, and no one had a history of hypertension, the first symptom of 5/13 people was irregular vaginal bleeding. Mean age of Group B patients at diagnosis was (52.7±10.2) years old, 53% (23/43) of patients were postmenopausal, and 28% (12/43) patients had the history of hypertension, the first symptom of 4 (9%, 4/43) people was irregular vaginal bleeding. The differences of age, menopause status, history of hypertension and initial symptoms between the two groups were statistically significant (all P<0.05). There were no significant differences in fertility history, dysmenorrhea history, age of menarche, history of endometriosis, preoperative and postoperative CA125 level, International Federation of Gynecology and Obstetrics (FIGO) stage, tumor grade, metastatic site and platinum-based chemotherapy drug resistance between the two groups (all P>0.05). The overall 5-year survival rate of OEC patients was 91.6%, and the overall 5-year progression-free survival rate was 76.6%. Among them, the 5-year survival rate of the OEC concurrent with simultaneous endometrial lesions group was 80.2%, and the pure OEC group was 93.4%; the 5-year progression-free survival rate of the OEC concurrent with simultaneous endometrial lesions group was 74.1%, and the 5-year progression-free survival rate of the pure OEC group was 77.3%. There were no significant differences between the two groups (all P>0.05). Multivariate analysis showed that the independent factors for the prognosis of OEC patients were FIGO stage (P=0.006) and residual lesion size (P=0.020). Conclusions: OEC patients have a high proportion of simultaneous endometrial lesions. OEC with simultaneous endometrial lesions are younger than patients with pure OEC. Synchronous endometrial lesions do not affect the prognosis of patients with OEC.
