Abstract
Objective: To investigate the prevalence trend of high normal blood pressure and elevated blood pressure in children and adolescents aged 7 to 17 years in China from 2010 to 2019. Methods: Students aged 7-17 years were selected from the Chinese National Survey on Students' Constitution and Health from 2010 to 2019. High normal blood pressure and elevated blood pressure were determined according to the "Reference of screening for elevated blood pressure among children and adolescents aged 7-18 years" (WS/T 610-2018). The Chi-square test was performed to determine whether there was a difference in the prevalence of high normal blood pressure and elevated blood pressure by gender, residence and age group. Results: In 2019, the prevalence of high normal blood pressure in children and adolescents aged 7-17 years was 15.3% (29 855/195 625), which was higher in boys (20.2%, 19 779/97 847) and rural areas (15.4%, 15 066/97 567) than that in girls (10.3%, 10 076/97 778) and urban areas (15.1%, 14 789/98 058), respectively (all P<0.05). The prevalence of elevated blood pressure was 13.0% (25 377/195 625), which was higher in girls (13.2%, 12 925/97 778) and rural areas (14.1%, 13 753/97 567) than that in boys (12.7%, 12 452/97 847) and urban areas (11.9%, 11 624/98 058) (all P<0.05). From 2010 to 2019, the prevalence of high normal blood pressure showed an increasing trend, with an annual average growth rate from 1.14% to 3.18%. The overall prevalence of elevated blood pressure also showed an increasing trend from 2010 to 2019 but decreased in 2014. The annual average growth rate of elevated blood pressure was-1.07% from 2010 to 2014 and 9.33% from 2014 to 2019. About 17 provinces had an increasing trend in the prevalence of elevated blood pressure from 2010 to 2014, and 22 provinces with an increasing trend from 2014 to 2019. There were obvious regional differences in the annual average growth rate of the prevalence of high normal blood pressure and elevated blood pressure. The regions with the highest annual average growth rate of the prevalence of high normal blood pressure were the Northeast (5.47%) from 2010 to 2014 and the Western region (5.21%) from 2014 to 2019. For elevated blood pressure, the Northeast had the highest annual average growth rate from 2010 to 2014 (12.35%), while the Central (15.79%) and Western (12.87%) had the highest growth rate from 2014 to 2019. Conclusion: From 2010 to 2019, the prevalence of high normal blood pressure and elevated blood pressure in Chinese Han children and adolescents aged 7 to 17 shows an increasing trend, with regional disparities.

Abstract
Objective Exposure to ambient particulate matter (PM2.5) is the leading risk factor for developing chronic obstructive pulmonary disease (COPD) in China. The present study aimed to investigate the trends in COPD mortality attributable to ambient PM2.5 exposure in China from 1990 to 2019. Methods Data on COPD burden attributable to ambient PM2.5 exposure in China were extracted from the Global Burden of Disease (GBD) study 2019. The estimated annual percentage change (EAPC) was used to assess COPD mortality from 1990 to 2019. The APC model was used to analyze the temporal trends in the rate of COPD mortality attributable to ambient PM2.5 exposure according to age, period, and cohort. Results Exposure to ambient PM2.5 contributed to 192.4 thousand deaths in 1990 and 263.6 thousand deaths in 2019. The age-standardized mortality rate (ASMR) and the age-standardized disability-adjusted life year rate (ASDR) due to ambient PM2.5 exposure showed a gradual downward trend, the ASMR and ASDR in 2019 decreased to 16.6 per 100,000 with an EAPC of -2.82 (95% CI: -8.61 to 3.34) and 278.6 per 100,000 with an EAPC of -2.02 (95% CI: -7.85 to 4.19), compared to those in 1990, respectively. The relative risk (RR) of COPD increased with age in females, while in males, mortality significantly increased from the levels among those in the 60-64 age group to that among those in the 90-94 age group. In the period group, the RR of COPD in males remained above 1.0 from the 2000 to 2004 period, but it gradually decreased in females. The cohort effect showed an overall downward trend. Conclusion Although the ASMR and ASDR are decreasing in Chinese patients with COPD, the number of deaths due to COPD is increasing. Ambient PM2.5 exposure is more harmful in males and older people above 60 years of age.

Abstract
BACKGROUND Spinal cord injury (SCI) is a crushing disease without a effective and specific therapeutic strategy. Therefore, it is crucial to uncover underlying mechanism in order to identify potential treatments for SCI. Current studies show ferroptosis might pay important role in SCI. METHODS In this study, we aimed to identify the key ferroptosis-related genes providing therapeutic targets for SCI. GSE45006, GSE19890 and GSE156999 from Gene Expression Omnibus (GEO) database were analyzed. RESULTS A total of 61 ferroptosis-related DEGs were identified, followed by bioinformatics enrichment analyses and PPI network construction. Ten key ferroptosis-related genes were identified by Cytoscape (Cytohubba), most of which were enriched in the HIF-1 signaling pathway. Then we constructed a clip SCI rat model and qPCR was performed to assess the expressions of five genes enriched in HIF-1 signaling pathway (Stat3, Tlr4, Hmox1, Hif1a and Cybb). Finally, a ceRNA network, Stat3, Tlr4, Hmox1/miR127, miR383, miR485/rno-Mut_0003, rno-Pwwp2a_0002 was constructed and expression of mentioned molecules were validated by chip data. CONCLUSIONS Five hub genes from HIF-1 signaling pathway were identified and might play a central role in SCI, which indicated that ferroptosis was correlated with HIF-1 signaling pathway. These results can provide a new insight into molecular mechanisms and identify potential therapeutic targets for SCI.

Abstract
Background The incidence and mortality trends of esophageal cancer (EC) remain unknown in China. This study aimed to describe the trend in incidence and mortality of EC in China. Methods We extracted age-standardized rates and numbers of EC in China for 1990−2019 from the Global Burden of Disease study 2019. The age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) were calculated to describe the trends, while the annual percentage of change and the average annual percent change (AAPC) were analyzed by the joinpoint regression analysis. The incidence and mortality data were analyzed via age-period-cohort model analysis. Results The ASIR and ASMR decreased slightly before 1999, then increased from 1999 to 2004, and decreased again thereafter, with overall AAPC values of −2.5 (−2.8, −2.1) for females and -0.9 (−1.1, −0.8) for males regarding incidence, with overall AAPC values of −3.1 (−3.3, −2.9) for females and −1.2 (−1.3, −1.1) for males regarding mortality. As a whole, the relative risk (RR) of EC increased with age in both females and males regarding incidence and mortality, except for the 80–84-year-old age group in females and the 85–89-year-old age group in males regarding incidence, where they began to decrease. The RR of EC increased with age in females and males regarding mortality, except for the 85–89-year-old age group in males. The time period showed a trend of first rising and then decreasing, and the RR of time period effect was lower in 2015 than that in 1990 in females regarding both incidence and mortality, whereas males showed a significant upward trend in both incidence and mortality. The birth cohort effect showed an overall downward trend. Conclusions The overall incidence and mortality of EC in China shows an increased and then decreased trend from 1990 to 2019. The AAPC decreased in incidence and mortality from 1990 to 2019. The RR of incidence and mortality of EC in China is greatly affected by age in both sexes, by time period in male, we should be paid more attention to.

Abstract
To evaluate the effects of two different reconstruction routes (the posterior mediastinal route (PR) and the retrosternal route (RR)) on the surgical outcomes of patients after esophagectomy for esophageal carcinoma. PubMed, Embase, Web of Science and Scopus were searched from database inception to March 2021. Randomized controlled trials (RCTs) and case-control trials on the surgical outcomes of patients undergoing esophagectomy via one of the two routes were included. RevMan 5.3 software was used for the meta-analysis. In total, 19 studies were included, 8 were RCTs and 11 were case-control studies. The meta-analysis showed that among the case-control trials, the PR had reduced rates of anastomotic leakage [odds ratio (OR) = 0.56, 95% confidence interval (CI) (0.43, 0.74), P < 0.01]. In addition, it had reduced rates of anastomotic stenosis [OR = 0.42, 95% CI (0.30, 0.59), P < 0.01] and pulmonary complications [OR = 0.63, 95% CI (0.47, 0.84), P < 0.01]. However, there was no significant difference in cardiac complications [RCTs, relative risk (RR) = 0.57, 95% CI (0.29, 1.11), P = 0.10; case-control trials, OR = 1.06, 95% CI (0.70, 1.62), P = 0.78] or postoperative mortality [RCTs, RR = 0.47, 95% CI (0.19, 1.16), P = 0.10; case-control trials, OR = 0.68, 95% CI (0.32, 1.44), P = 0.31]. Compared with the RR, the PR had reduced rates of anastomotic leakage, anastomotic stenosis and pulmonary complications.

Abstract
Objective: We aimed to assess the effects of outdoor time in preventing incident myopia among primary school students and evaluate its differences among different grades to provide evidence for policy formulation related to myopia prevention. Methods: This study is a cohort study. We investigated 6 046 grade 1 to 5 students in 9 provinces, Jiangsu, Shanghai, Fujian, Shanxi, Henan, Hunan, Gansu, Chongqing, and Guangxi. In 2019, we measured their myopia on site. In 2020, we did a follow-up visit on those students to detect the myopia incidence rate. Information regarding outdoor time and myopia-related behaviors were obtained from a questionnaire within one week of visual acuity measurement in 2020. The chi-square test and Cochran-Armitage trend test compared the differences between groups. The Cox proportional hazards risk model was used to test the relationship between outdoor time and myopia. Results: In 2020, the overall myopia incidence rate of grade 1 to 5 students in the baseline was 27.5%; while 23.0% in grades 1 and 2 students and 31.7% in grades 3 to 5 students, respectively. After controlling for covariates, for students in grade 1 to 2, those with ≥1 hour of outdoor time per day were at 0.76 (95%CI: 0.62-0.93, P=0.008) times risk of being myopia than that of students with <1 hour of outdoor time per day; while for students in grades 3 to 5, an average of ≥3 hours of outdoor time per day was required to have a significant protective effect on myopia. The students with ≥3 hours of outdoor time per day were less likely to be myopia (OR=0.75, 95%CI: 0.61-0.93, P=0.007) than those students with <3 hours of outdoor time per day. Conclusions: For grade 1 and 2 students, 1 hour of outdoor time per day could reduce the incidence of myopia, whereas for grade 3 to 5 students, 3 hours of outdoor time per day could effectively reduce the incidence of myopia. Therefore, the recommendations for outdoor time as myopia prevention should be different for different grades. The higher the grade is, the more outdoor time should be spent to reduce myopia incidence. Moreover, other factors that affect myopia's incidence should be also paid attention to, and a comprehensive approach should be adopted to prevent and control the incidence of myopia.

Abstract
Background This study assessed health inequality in the global burden of chronic obstructive pulmonary disease (COPD) between 1990 and 2019 using data extracted from the Global Burden of Diseases (GBD 2019) study. Methods Data were extracted from the GBD 2019 study. A series of comparative and descriptive analyses of the disease burden between women and men in countries with different socioeconomic development (SDI) status were performed. The slope index of inequality (SII), relative index of inequality (RII), and concentration index (CI) were calculated to measure the socioeconomic-related cross-national health inequity between 1990 and 2019. Results The global health burden caused by COPD increased by 25.7% in terms of disability-adjusted life years (DALY) from 59.2 million years in 1990 to 74.4 million years in 2019. Global age-standardized DALY rate (ASDR) associated with COPD decreased by 40.0%, from 1537.7 per 100,000 population in 1990 to 926.1 per 100,000 population in 2019. The highest sex-specific DALY number was at age 70–74 in male and female, and female is lower than male. However, after controlling for population size, the burden of COPD is more concentrated in the population living in low SDI countries, relative health inequality indicators (RII and CI) supported this conclusion. Conclusion The health inequalities caused by the disparity of socioeconomic status are increasing, and the increasing concentration of wealth worldwide is likely to aggravate health inequalities associated with COPD.

Abstract
Objectives Occupational exposure to carcinogens is associated with trachea, bronchus, and lung (TBL) cancer. The objective of this study was to provide global and regional estimates of the burden of TBL cancer associated with occupational carcinogens (OCs) between 1990 and 2019. Methods Age-standardized mortality rates (ASMR) and age-standardized disability-adjusted life years (DALYs) rates (ASDR) of TBL cancer related to exposure to OCs at the global and regional levels were extracted for 1990–2019 from the Global Burden of Disease 2019. Joinpoint regression was used to analyze trends in the ASMR and ASDR of TBL cancer burden related to OCs, and the annual percent change and the average annual percent change (AAPC) were recorded. Results The mortality from TBL cancer related to exposure to OCs increased globally. The ASMR and ASDR decreased in both sexes and in men between 1990 and 2019. The AAPC of ASMR and ASDR decreased in men between 1990 and 2019, but increased in women. Asbestos accounted for the highest death number and beryllium accounted for the lowest; diesel engine exhaust caused the largest percentage change in death number (145.3%), in ASDR (14.9%), and in all ages DALY rates (57.6%). Asbestos accounted for the largest death number in high social development index (SDI) countries, whereas low-middle SDI countries had the largest percent change (321.4%). Asbestos was associated with decreased ASDR in high SDI countries and increased ASDR in low-middle SDI countries, and similar changes were observed for other OCs. Conclusions The overall mortality and DALYs of TBL cancer burden related to OCs showed a decreasing trend between 1990 and 2019, whereas death number increased. Asbestos accounted for the highest death number. TBL cancer burden related to OCs decreased to different degrees in high, low, low-middle, and middle SDI countries, which showed variable levels of TBL cancer burden related to exposure to OCs (except asbestos).

Abstract
Combinatorial drug therapy has attracted substantial attention as an emerging strategy for the treatment of diseases with complex pathological mechanisms. We previously developed a potentially universal computational screening approach for combination drugs and used this approach to successfully identify some beneficial combinations for the treatment of heart failure. Herein, this screening approach was used to identify novel combination drugs for the treatment of epilepsy in an approved drug library. The combination of guaifenesin-andrographolide was first discovered as a promising therapy with synergistic anticonvulsant activities in maximal electroshock (MES)- and subcutaneous pentylenetetrazol (sc-PTZ)-induced epilepsy models in vivo. The studies of network analysis, fluorescence imaging, and N-methyl-d-aspartate (NMDA)-induced cytotoxicity further revealed that guaifenesin-andrographolide might synergistically affect NMDA receptors and then alleviate the pathogenesis of epilepsy. Therefore, we report that the combination of guaifenesin-andrographolide exerts effects against epilepsy through a novel synergistic mechanism and is thus a potential treatment for epilepsy, providing a promising mechanism for the design of novel combinatorial drug treatments against epilepsy.

Abstract
Selective elimination of senescent cells (senolysis) has become a promising therapeutic strategy for the management of chronic renal failure (CRF), but the senolytic molecular pathways towards CRF therapy are limited. Here, we present for the first time a senescence-associated β-galactosidase (SA-β-gal) activatable theragnostic prodrug strategy to pertinently and effectively treat CRF in mice with the aid of fluorescence-guided senolysis. The signs of premature senescence, including the overexpression of β-gal, have been found in kidneys of mice with CRF, making this enzyme particularly suitable as a trigger of prodrugs for CRF therapy. With this unique design, our pioneering prodrug TSPD achieved the activation of a fluorophore for tracking and the specific release of the parent drug, gemcitabine, in β-gal-enriched cells after activation with SA-β-gal. In mice with CRF, abdominal administration of TSPD was effective for improvement of the kidney functions, supporting the feasibility of the SA-β-gal-dependent senolysis therapy towards CRF. Here, we report a senescence-associated β-galactosidase activatable theragnostic prodrug to pertinently treat chronic renal failure (CRF) in mice with the aid of fluorescence-guided senolysis, providing a creative molecular approach to CRF therapy.![]()

Abstract
Diagnosing aging for preventative intervention generally relies on the tracking of aging biomarkers in the resting state. However, the static marker levels are insufficient to fully evaluate aging, particularly given that the stress response capacity (SRC) decay is currently viewed as a critical feature of aging. Therefore, we have developed a dual-channel fluorescent probe ROKS capable of the logic-based visualization of thiophenol (stressor) and HOCl (thiophenol-activated stress response product) in vivo, which provides a new strategy from the time dimension to precisely assess the SRC of individuals under stress using the dual-channel fluorescence ratio. Using ROKS we observed that the SRC of live cells decayed with senescence, and that a higher SRC was found for young vs. aged Caenorhabditis elegans. As such, our study offers a promising strategy for the fluorescence-guided diagnosis of aging and paves the way for accurate evaluation of the efficacy of anti-aging drugs. Rather than tracking aging using the resting state, ROKS, an optical probe, was developed for evaluating the degree of aging dynamically by precisely monitoring the stress response of individuals under stress.![]()

Abstract
A Sagnac loop interferometer based on concatenated polarization-maintaining fiber (PMF) tapers is proposed for simultaneous measurement of seawater salinity and temperature. The influences of the distance between the PMF tapers as well as fiber taper diameter on sensor performance have been investigated. Experimental results indicate that the fabricated sensor with a distance of 3 cm between adjacent fiber tapers possesses the salinity and temperature sensitivities of 0.367 nm/% and -0.728nm/∘C, respectively, and the taper waist diameter of 20 µm would help to improve salinity sensitivity in comparison with a sensor of 30 µm in diameter. The proposed Sagnac loop interferometer based on concatenated PMF tapers is expected to find potential applications in the measurement of seawater salinity.

Abstract
OBJECTIVE Osteoarthritis (OA) is the most prevalent age-related disorder due to cartilage degradation. Previous studies have identified aberrant chondrocyte homeostasis under extracellular stress as a key pathological mechanism behind cartilage degradation in OA. TDP-43, a DNA/RNA-binding protein has been demonstrated to participate in processing many extracellular stress responses; however, understanding of the role of TDP-43 in OA is limited. This study aims to investigate the role of TDP-43 in chondrocyte homeostasis and cartilage degradation in OA. METHODS The role of TDP-43 during degradation of cartilage is examined by experimental posttraumatic OA animal models and human cartilage specimens. Cartilage degradation is assessed by histological analysis, qPCR, and Western blot. The molecular mechanisms are investigated in vitro using human primary chondrocytes. RESULTS TDP-43 decreases significantly in degenerated cartilage. TDP-43 concentration is positively correlated with IL-1β concentration in synovial fluid derived from OA patients (Pearson r = 0.95, CI (95%) [0.80, 0.99], P < 0.0001). Intra-articular injection of recombinant TDP-43 significantly alleviates cartilage degradation and subchondral bone remodeling in vivo. In vitro mechanistic analyses show that TDP-43 maintains chondrocyte homeostasis under oxidative stress through regulating stress granule dynamics via G3BP1. CONCLUSION The present study indicates that TDP-43 maintains chondrocyte homeostasis under oxidative stress and alleviates cartilage degeneration in osteoarthritis, identifying TDP-43 as a potential target for the diagnosis and treatment of knee OA.

Abstract
Combination drugs, characterized by high efficacy and few side effects, have received extensive attention from pharmaceutical companies and researchers for the treatment of complex diseases such as heart failure (HF). Traditional combination drug discovery depends on large-scale high-throughput experimental approaches that are time-consuming and costly. Herein we developed a novel, rapid, and potentially universal computer-guided combination drug-network-screening approach based on a set of databases and web services that are easy for individuals to obtain and operate, and we discovered for the first time that the menthol-allethrin combination screened by this approach exhibited a significant synergistic cardioprotective effect in vitro. Further mechanistic studies indicated that allethrin and menthol could synergistically block calcium channels. Allethrin bound to the central cavity of the voltage-dependent L-type calcium channel subunit alpha-1S (CACNA1S) lead to a conformational change in an allosteric site of CACNA1S, thereby enhancing the binding of menthol to this allosteric site. In summary, we reported a potentially universal computational approach to combination drug screening that has been used to discover a new combination of menthol-allethrin against HF in vitro, providing a new synergistic mechanism and prospective agent for HF treatment.

Abstract
Background Circular RNAs (circRNAs), a new class of regulatory noncoding RNAs, are involved in gene regulation and may play a role in cancer development. The aim of this study was to identify circRNAs involved in lung adenocarcinoma (LUAD) using bioinformatics analysis. Methods CircRNA (GSE101684, GSE101586), miRNA (GSE135918), and mRNA (GSE130779) microarray datasets were downloaded from the Gene Expression Omnibus (GEO) database to identify differentially expressed circRNAs (DECs), miRNAs (DEMs), and mRNAs (DEGs) in LUAD. Circinteractome and StarBase were used to predict miRNAs and mRNAs, respectively. A circRNA-miRNA-mRNA-ceRNA network was constructed. Patient survival was analyzed using UALCAN, and a sub-network was established. Real-time quantitative PCR (qRT-PCR) was used to verify the expressed of DECs between LUAD tissues and paired adjacent normal tissues. Results Hsa_circ_0072088 was identified as a differentially expressed (upregulated) circRNA in the two datasets. Intersection analysis identified hsa-miR-532-3p and hsa-miR-942 as the two miRNAs with the highest potential for binding to hsa_circ_0072088. Differential expression analysis and target gene prediction were performed to build a ceRNA network of hsa_circ_0072088 using Circinteractome/StarBase 3.0. Intersection analysis showed that TMEM52, IL24, POF1B, KIF1A, NHS, LBH, HIST2H2BE, ABCC3, PYCR1, CD79A, IGF2BP3, ANKRD17, GTSE1, MKI67, CLSPN, PLAU, LUC7L, MAGIX, GPATCH4, and ABAT were potential downstream mRNAs. The association between the expression level of 20 DEGs and LUAD patient survival was analyzed using UALCAN and GEPIA, which showed that IGF2BP3, MKI67, CD79A, and ABAT were related to patient survival. Hsa_circ_0072088 was verified upregulated by qRT-PCR. Conclusion The circRNA hsa_circ_0072088, the DEMs (hsa-miR-532-3p and hsa-miR-942-5p), and the DEGs (IGF2BP3, MKI67, CD79A, and ABAT) may serve as prognostic markers in LUAD.

Abstract
UNLABELLED The features extracted from diagnostic computed tomography (CT) slices were used to qualitatively detect bone mineral density (BMD) through neural network models, and the evaluation results indicated that it may be a promising approach to perform osteoporosis screening in clinical practice. INTRODUCTION The purpose of this study is to design a novelty diagnostic method for osteoporosis screening by using the convolutional neural network (CNN), which can be incorporated into the procedure of routine CT diagnostic in medical examination thereby improving the osteoporosis diagnosis and reducing the patient burden. METHODS The proposed CNN-based method mainly comprises two functional modules to perform qualitative detection of BMD by analyzing the diagnostic 2D CT slice. The first functional module aims to locate and segment the ROI of diagnostic 2D CT slice, called Mark-Segmentation-Network (MS-Net). The second functional module is used to determine the category of BMD by the features of ROI, called BMD-Classification-Network (BMDC-Net). The diagnostic 2D CT slice of pedicle level in lumbar vertebrae (L1) was selected from 3D CT image in our experiments firstly. Then, the trained MS-Net can get the mark image of input original 2D CT slice, thereby obtain the segmentation image. Finally, the trained BMDC-Net can obtain the probability value of normal bone mass, low bone mass, and osteoporosis by inputting the segmentation image. On the basis of network results, the radiologists can provide preliminary qualitative diagnosis results of BMD. RESULTS Training of the network was performed on diagnostic 2D CT slices of 150 patients. The network was tested on 63 patients. Each patient corresponds to a 2D CT slice. The proposed MS-Net has an excellent segmentation precision on the shape preservation of different lumbar vertebra. The dice index (DI), pixel accuracy (PA), and intersection over union (IOU) of segmentation results are greater than 0.8. The proposed BMDC-Net achieved an accuracy of 76.65% and an area under the receiver operating characteristic curve of 0.9167. CONCLUSIONS This study proposed a novel method for qualitative detection of BMD via diagnostic CT slices and it has great potential in clinical applications for osteoporosis screening. The method can potentially reduce the manual burden to radiologists and diagnostic cost to patients.
