Abstract
INTRODUCTION This study aimed to investigate the relationship between age of myopia onset and high myopia and to explore if age of onset mediated the associations of high myopia with parental myopia and time spent on electronics. METHODS This cross-sectional study enrolled 1118 myopic patients aged 18 to 40. Information was obtained via a detailed questionnaire. Multivariable logistic regression and linear regression models were utilized to assess age of onset in relation to high myopia and spherical equivalent refractive error, respectively. Structural equation models examined the mediated effect of onset age on the association between parental myopia, time spent on electronics and high myopia. RESULTS An early age at myopia onset was negatively correlated with spherical equivalent refractive power. Subjects who developed myopia before the age of 12 were more likely to suffer from high myopia than those who developed myopia after the age of 15. Age of myopia onset was the strongest predictor of high myopia, with an area under the curve (AUC) in Receiver Operator Characteristic (ROC) analysis of 0.80. Additionally, age of myopia onset served as a mediator in the relationships between parental myopia, electronic device usage duration, and the onset of high myopia in adulthood. CONCLUSIONS Age of myopia onset might be the single best predictor for high myopia, and age at onset appeared to mediate the associations of high myopia with parental myopia and time spent on electronics.

Abstract
Objective: To investigate the changes of spinal vascular blood flow in SD rats after cervical, thoracic and lumbar spinal cord injury (SCI) using super-resolution ultrafast ultrasound technology. Methods: A total of 9 SD rats were used to construct SCI models at different segments using a 50 g aneurysm clip. Super-resolution ultrafast ultrasound technology was used to perform vascular blood flow imaging on the spinal cord of rats before and after injury at 6 hours, obtaining quantitative information such as spinal cord vascular density and blood flow velocity. Results: Ultrasound imaging showed that after SCI, the vascular density in the thoracic segment decreased (18.16%±1.04%) more than in the cervical segment (11.42%±1.39%) and lumbar segment (13.88%±1.43%, both P<0.05). The length of the spinal cord with decreased vascular density in the thoracic segment [(4.80±0.34)mm] was longer than that in the cervical segment [(2.80±0.57)mm] and lumbar segment [(3.10±0.36)mm, both P<0.05]. After injury, the decrease of blood flow in the thoracic segment [(8.87±0.85)ml/min] was higher than that in the cervical segment [(4.88±0.56)ml/min] and lumbar segment [(6.19±0.71)ml/min, both P<0.05]. HE staining and Nissl staining showed that the proportion of cavity area after thoracic SCI (11.53%±0.93%) was higher than that in the cervical segment (4.90%±1.72%) and lumbar segment (7.64%±0.84%, both P<0.05). The number of Nissl bodies in the thoracic segment (18.0±5.3) was also lower than that in the cervical segment (32.3±5.1) and lumbar segment (37.0±5.6) (both P<0.05). Conclusions: There are different changes in vascular blood flow after SCI in different segments of rats. The same injury causes the most severe damage to blood vessels in the thoracic spinal cord, followed by the lumbar spinal cord, and the cervical spinal cord has the least damage.

Abstract
AIM To compare the clinical efficacy and safety of first-line treatments for advanced unresectable oesophageal squamous cell cancer. MATERIALS AND METHODS A systematic review and network meta-analysis was carried out by retrieving and retaining relevant literature from databases. The studies were randomised controlled trials comparing first-line treatments for advanced unresectable oesophageal squamous cell cancer. A Bayesian network meta-analysis was used to assess clinical outcomes. RESULTS Nine studies including 4499 patients receiving first-line treatments were analysed. For all populations, toripalimab plus chemotherapy tended to provide the best overall survival (hazard ratio 0.58, 95% confidence intervals 0.43-0.78) and sintilimab plus chemotherapy provided the best progression-free survival (0.56, 0.46-0.68). Nivolumab plus chemotherapy presented the best objective response rate (odds ratio 2.45, 1.78-3.42) and camrelizumab plus chemotherapy (0.47, 0.29-0.74) appeared to be the safest. Sintilimab plus chemotherapy (0.55, 0.40-0.75) and nivolumab (0.54, 0.37-0.80) plus chemotherapy had the best overall survival in programmed death ligand 1 (PD-L1) tumour proportion score <1% and ≥1% subgroups. Toripalimab plus chemotherapy (0.61, 0.40-0.93) and pembrolizumab (0.57, 0.43-0.75) were the best in overall survival in combined positive score <10 and ≥10 subgroups, respectively. Toripalimab plus chemotherapy showed the best overall survival in the Asian group; pembrolizumab presented better overall survival in the Asian population than the non-Asian group. CONCLUSION Most immunotherapy combined with chemotherapy showed superior clinical benefits and sintilimab plus chemotherapy, toripalimab plus chemotherapy and tislelizumab plus chemotherapy had better comprehensive clinical efficacy. PD-L1 expression detection and ethnicity differences are still of great significance and most suitable regimens varied from each subgroup.

Abstract
AIMS Perineural invasion (PNI) is a special type of metastasis of several cancers and has been reported as being a factor for poor prognosis in colorectal carcinoma. However, investigations of PNI in only rectal cancer and a comprehensive analysis combining meta-analyses with real-world case studies remain lacking. MATERIALS AND METHODS First, articles from 2000 to 2020 concerning the relationship between PNI and rectal cancer prognoses and clinical features were meta-analysed. Subsequently, we carried out a retrospective analysis of 312 rectal cancer cases that underwent radical surgery in the real world. The incidence of PNI and the relationship between PNI and prognosis, as well as clinicopathological factors, were investigated. RESULTS The incidence of PNI was 23.09% and 33.01% in the meta-analysis and clinical cases, respectively. PNI occurred as early as stage I (2.94%). Moreover, neoadjuvant therapy significantly reduced the PNI-positive rate (20.34% versus 26.54%). Both meta-analysis and real-world clinical case studies suggested that PNI-positive patients had poorer prognoses than PNI-negative patients. We established an effective risk model consisting of T stage, differentiation and lymphovascular invasion to predict PNI in rectal cancer. CONCLUSION PNI is a poor prognostic factor for rectal cancer and could occur even in stage I. Additionally, neoadjuvant therapy could sufficiently reduce the PNI-positive rate. T stage, lymphovascular invasion and differentiation grade were independent risk factors for PNI and the risk model that included these factors could predict the probability of PNI.

Abstract
The neovascular form of age-related macular degeneration (nvAMD) is the leading cause of blindness in the elderly population. Vascular endothelial growth factor (VEGF) plays a crucial role in choroidal neovascularization (CNV), and anti-VEGF therapy is recommended as first-line therapy for nvAMD. However, many patients do not radically benefit from this therapy. Epidemiological data suggest that physical exercise is beneficial for many human diseases, including nvAMD. Yet, its protective mechanism and therapeutic potential remain unknown. Here, using clinical samples and mouse models, we found that exercise reduced CNV and enhanced anti-angiogenic therapy efficacy by inhibiting AIM2 inflammasome activation. Furthermore, transfusion of serum from exercised mice transferred the protective effects to sedentary mice. Proteomic data revealed that exercise promoted the release of adiponectin, an anti-inflammatory adipokine from adipose tissue into the circulation, which reduced ROS-mediated DNA damage and suppressed AIM2 inflammasome activation in myeloid cells of CNV eyes through AMPK-p47phox pathway. Simultaneous targeting AIM2 inflammasome product IL-1β and VEGF produced a synergistic effect for treating choroidal neovascularization. Collectively, this study highlights the therapeutic potential of an exercise-AMD axis and uncovers the AIM2 inflammasome and its product IL-1β as potential targets for treating nvAMD patients and enhancing the efficacy of anti-VEGF monotherapy.

Abstract
The prevalence of dry eye in children is increasing with changes in the environment and the widespread use of electronic products. However, due to poor ability to express themselves and hidden symptoms of children, lack of understanding of dry eye in children, children with dry eye are likely to be misdiagnosed. Dry eye can seriously affect the quality of children's learning, life, vision and visual development. Therefore, it is urgent to raise awareness of clinical workers about dry eye in children, prevent the occurrence of related complications of dry eye, and avoid permanent visual damage to children. This review discusses and summarizes the epidemiology and common risk factors of children with dry eye, with the aim of improving doctors' understanding of dry eye in children.

Abstract
To explore the digital manufacturing process of distal extension removable partial denture. From November 2021 to December 2022, 12 patients (7 males and 5 females) with free-ending situation were selected from the Department of Prosthodontics, School of Stomatology, The Fourth Military Medical University. Three-dimensional model of the relationship between alveolar ridge and jaw position was obtained by intraoral scanning technique. After routine design, manufacturing and try-in of metal framework for removable partial denture, the metal framework was located in the mouth and scanned again to obtain the composite model of dentition, alveolar ridge and metal framework. The free-end modified model is obtained by merging the digital model of free-end alveolar ridge with the virtual model with the metal framework. The three-dimensional model of artificial dentition, and base plate was designed on the free-end modified model, and the resin model were made by digital milling technology. The removable partial denture was made by accurately positioning the artificial dentition and base plate, bonding metal framework with injection resin, grinding and polishing the artificial dentition and resin base. Compared with the design data after clinical trial, the results showed that there was an error of 0.4-1.0 mm and an error of 0.03-0.10 mm in the connection between the resin base of artificial dentition and the connecting rod of the in-place bolt and the connection between artificial dentition and resin base. After denturen delivery, only 2 patients needed grinding adjustment in follow-up visit due to tenderness, and the rest patients did not find any discomfort. The digital fabrication process of removable partial denture used in this study can basically solve the problems of digital fabrication of free-end modified model and assembly of artificial dentition with resin base and metal framework.

Abstract
The pathological retinal angiogenesis often causes blindness. Current anti-angiogenic therapy for proliferative retinopathy targets the vascular endothelial growth factor (VEGF), but many patients do not radically benefit from this therapy. Herein, we report that circulating prostaglandin (PG) F2α metabolites were increased in type 2 diabetic patients with proliferative retinopathy, and the PGF2α receptor (Ptgfr) was upregulated in retinal endothelial cells (ECs) from a mouse model of oxygen-induced retinopathy (OIR). Further, disruption of the PTGFR receptor in ECs attenuated OIR in mice. PGF2α promoted the proliferation and tube formation of human retinal microvascular endothelial cells (HRMECs) via the release of ELR+ CXC chemokines, such as CXCL8 and CXCL2. Mechanistically, the PGF2α /PTGFR axis potentiated ELR+ CXC chemokine expression in HRMECs through the Gq /CAMK2G/p38/ELK-1/FOS pathway. Upregulated FOS-mediated ELR+ CXC chemokine expression was observed in retinal ECs from PDR patients. Moreover, treatment with PTGFR inhibitor lessened the development of OIR in mice in a CXCR2-dependent manner. Therefore, inhibition of PTGFR may represent a new avenue for the treatment of retinal neovascularization, particularly in PDR.

Abstract
BACKGROUND AND PURPOSE In patients with Moyamoya disease, the relationship between preoperative hemodynamic status and prognosis after encephalo-duro-arterial synangiosis (EDAS) surgery was unclear. We aimed to explore the value of the preoperative hemodynamic status acquired by cine phase-contrast MR imaging in predicting collateral formation and clinical outcomes after EDAS surgery in patients with Moyamoya disease. MATERIALS AND METHODS Participants with Moyamoya disease were prospectively recruited and underwent preoperative phase-contrast MR imaging. All participants were classified into good and poor groups according to the collateral formation after EDAS surgery. On the basis of the change in the mRS system, participants were classified into the improved mRS group and the poor response group. Hemodynamic status including mean velocity, peak velocity, and blood volume flow of the superficial temporal artery was compared between groups. Logistic regression was performed to relate the phase-contrast MR imaging parameters to collateral formation and clinical outcomes. RESULTS A total of 45 patients with Moyamoya disease with unilateral EDAS surgery were finally included. Mean velocity, peak velocity, and blood volume flow of the ipsilateral superficial temporal artery were significantly greater in patients with good collateral formation compared with those with poor collateral formation (P = .011, .004, and .013, respectively). The mean velocity, peak velocity, and blood volume flow were independently associated with postoperative collateral formation after adjusting for confounding factors. Furthermore, the peak velocity of the ipsilateral superficial temporal artery was also significantly associated with improvement of the mRS score. CONCLUSIONS Good hemodynamic status of the ipsilateral superficial temporal artery as a donor artery evaluated by phase-contrast MR imaging was significantly associated with better collateral formation and improved mRS after EDAS surgery in patients with Moyamoya disease.

Abstract
OBJECTIVE To explore the association between postpartum depression (PPD) and transforming growth factor-β (TGF-β) concentrations in human colostrum. METHODS Participants were recruited from a maternal and infant cohort established in a tertiary general hospital in Guangdong Province between December, 2020 and September, 2021. In the afternoon of the second postpartum day, the women were evaluated with Edinburgh Postnatal Depression Scale (EPDS) for screening PPD (defined as a score of 10 or higher). The women with PPD were matched at a 1:1 ratio with women without PPD with maternal age difference within 5 years and the same mode of delivery. Colostrum samples were collected in morning on the third postpartum day for measurement of TGF-β concentrations using enzyme-linked immunosorbent assay (ELISA), and the association between EPDS scores and TGF-β concentrations was analyzed in the two groups. RESULTS A total of 90 women were included in the final analysis. The mean concentrations of TGF-β1, TGF-β2 and TGF-β3 in the colostrum were 684.03 (321.22-859.25) pg/mL, 5116.50±1747.04 pg/mL and 147.84±48.68 pg/mL in women with PPD, respectively, as compared with 745.67 (596.00-964.22) pg/mL, 4912.40±1516.80 pg/mL, and 168.21±48.15 pg/mL in women without PPD, respectively. Compared with women without PPD, the women with PPD had significantly lower concentrations of TGF-β1 (P=0.026) and TGF-β3 (P=0.049) in the colostrum. Spearman correlation analysis revealed that the EPDS scores were negatively associated with the concentrations of TGF-β1 (r=-0.23, P=0.03) and TGF-β3 (r=-0.25, P=0.02) in the colostrum. CONCLUSION PPD is associated with decreased concentrations of TGF-β1 and TGF-β3 in human colostrum, suggesting the need of early PPD screening and interventions during pregnancy and the perinatal period to minimize the impact of PPD on human milk compositions.

Abstract
Abstract
Background
Tumor cell extensions called tumor microtubes (TMs) in glioma resemble neurites during neurodevelopment and connect glioma cells to a network that has considerable relevance for tumor progression and therapy resistance. The determination of interconnectivity in individual tumors has been challenging and the impact of tumor cell connectivity on patient survival remained unresolved so far.
Material and Methods
A connectivity signature was derived by single-cell RNA-sequencing (scRNA-Seq) of highly and lowly connected cells obtained from an SR101 dye transfer xenograft model of primary glioblastoma (GB). The signature was validated in different in vitro models of cell-to-cell connectivity and could be translated to GB clinical specimens.
Results
34 of 40 connectivity genes were related to neurogenesis, neural tube development or glioma progression, including the TM-network-relevant GAP43 gene. Astrocytic-like and mesenchymal-like GB cells had the highest connectivity signature scores in scRNA-Seq data of patient-derived xenografts and patient samples. In 230 human GBs, high connectivity correlated with the mesenchymal expression subtype, TP53 wildtype, and with dismal patient survival. CHI3L1 was identified and validated as a robust molecular marker of connectivity with a functional relevance.
Conclusion
The connectivity signature gives novel insights into brain tumor biology, provides a proof-of-principle that tumor cell connectivity is relevant for patients’ prognosis, and serves as a robust biomarker that can be used for future clinical trials

Abstract
BackgroundCommon approaches to valuing health technologies often fail to capture outcomes that matter to patients and families. The treatment goals of people living with rheumatoid arthritis (RA) include common trial endpoints but also include other facets of disease impact. Identifying a feasible and rigorous approach to inclusion of the patient perspective is needed as trialists increasingly seek to incorporate patient-important outcomes in trial design and as varied patient-centered value assessment frameworks emerge. No standard approach is available to systemically identify and quantify patient-important outcomes, nor to include those outcomes in deliberative decision-making. We developed the Patient-Engaged Healthcare Valuation strategy, using principles of goal attainment scaling to frame survey-based goal collection directly from adults.ObjectivesTo develop and test a goal-based method for collecting RA patient input for use in clinical trials and value assessment and evaluating the feasibility of this approach in people with RA.MethodsPatient goals and domains were identified from (1) a literature review (2010-2020) of patient outcomes, goals, and preferences in RA, and (2) discussions with patients and clinicians during two meetings with a steering committee (SC) consisting of clinicians, outcomes researchers, patients/advocates, and health economists. These goals informed the development of a draft survey. Adults with RA were recruited from online patient networks to rate goal importance and suggest additional goals. SC members reviewed the survey findings and assessed feasibility of scaling up goal collection for HTA.ResultsOf 135 articles identified, 17 were retained. An inductive and iterative approach was used to identify and thematically group the final set of 36 goals into 4 domains. The draft survey was cognitively debriefed with 4 adults with RA. The first survey was administered to 20 participants; results informed item revisions and additions for the second round of data collection (n=27).The 47 respondents were mostly White (87%), college-educated (72%) women (93%) living with RA for an average of 15 years; 75% rated their RA as moderate to severe. Free-text goals added in round 1 include: 1) finding specialists who listen to patient input on symptoms; 2) addressing loneliness or isolation; and 3) finding support from or helping others with RA. All Symptom and Life Impact goals were rated as Important or Very Important by ≥85% of participants; endorsement for Management and Treatment goals was somewhat more variable, with ≥85% endorsing these as Somewhat to Very Important. Results suggested that domains match key goals. Steering committee ratings supported the feasibility of this method.ConclusionGoals relevant for RA treatment evaluation can be efficiently identified and rated for importance by patients. Patient-important goals can be incorporated into deliberative healthcare valuation using this method to permit “crowd-sourced” input from people living with RA and to capture heterogeneous patient perspectives in healthcare valuation.Table 1.Top Goals based on rating as “Very Important” by >70% of subjects, from set of 36. “My goals for living with RA are to…”GoalsNot ImportantSomewhat ImportantImportantVery ImportantSymptom Managementimprove the quality of my life with RA0% (0)0% (0)23% (11)77% (36)manage my RA pain0% (0)2% (1)11% (5)87% (41)reduce how my RA pain interferes with my life0% (0)9% (4)17% (8)74% (35)Life Impactreduce the ways in which RA interferes with my life0% (0)2% (1)21% (10)77% (36)be independent in my daily functioning0% (0)4% (1)15% (4)81% (22)Managing my RAfeel like I can manage my RA0% (0)2% (1)26% (12)72% (34)Treatment Featuresunderstand my RA treatment options0% (0)4% (2)21% (10)74% (35)have the information I need to make treatment decisions0% (0)0% (0)19% (9)81% (38)know what to expect with my RA treatment0% (0)2% (1)23% (11)74% (35)find treatments that are effective0% (0)0% (0)6% (3)94% (44)AcknowledgementsI have no acknowledgements to declare.Disclosure of InterestsNone declared

Abstract
OBJECTIVE To investigate the role of miRNAs in amniotic fluid exosomes in growth and development of fetuses with Down syndrome (DS). METHODS Amniotic fluid were collected from 20 fetuses with DS and 20 normal fetuses (control) to extract amniotic exosome miRNA. MicroRNA sequencing technique was used to identify the differentially expressed miRNAs between the two groups, for which gene ontology (GO) and pathway analysis was performed. Three differentially expressed miRNAs with the strongest correlation with DS phenotype were selected for qPCR verification. Dual luciferase reporter assay was used to verify the activity of let-7d-5p for targeted regulation of BACH1. RESULTS We identified 15 differentially expressed miRNAs in DS as compared with the control group, among which 7 miRNAs were up-regulated and 8 were down-regulated. Target gene prediction results showed that the differentially expressed miRNAs targeted 17 DS-related genes. GO analysis revealed that the main functions of the target genes involved protein binding, protein transport, ATP binding, transferase activity and synapses. Pathway analysis revealed that the functional pathways were closely related with the development of the nervous system. qPCR results showed that the expression levels of miR-140-3p and let-7d-5p were significantly lower in DS group than in the control group (P < 0.05), as was consistent with miRNA sequencing results; the expression level of miR-4512 was significantly higher in DS group than in control group (P < 0.05), which was contrary to miRNA sequencing results. The results of double luciferase reporter gene assay confirmed that let-7d-5p was capable of targeted regulation of BACH1 expression. CONCLUSION Let-7d-5p in amniotic fluid exosomes may promote oxidative stress events in the brain of fetuses with DS by regulating BACH1 expression.

Abstract
In one-dimensional particle-in-cell simulations of a plasma irradiated by linearly polarized lasers from both sides of boundaries, it is found that there is an appreciable growth of the electromagnetic field in cavitons in the transverse direction perpendicular to the direction of polarization, which indicates the polarization conversion of the electromagnetic field in cavitons. This paper demonstrates the mechanism of this phenomenon based on parametric resonance induced by ponderomotive force with twice the frequency of the electromagnetic radiation in the caviton. We develop a theoretical model and verify it with simulation results. This phenomenon contributes to the heating and acceleration of particles and traps more EM energy in cavitons.

Abstract
OBJECTIVE The aim of this study is to analyze the association between coronary artery vitamin D receptor (VDR) expression and systemic coronary artery atherosclerosis (CAA) risk factors. METHODS Female cynomolgus monkeys (n = 39) consumed atherogenic diets containing the women's equivalent of 1000 IU/day of vitamin D3. After 32 months consuming the diets, each monkey underwent surgical menopause. After 32 postmenopausal months, CAA and VDR expression were quantified in the left anterior descending coronary artery. Plasma 25OHD3, lipid profiles and serum monocyte chemotactic protein-1 (MCP-1) were measured. RESULTS In postmenopausal monkeys receiving atherogenic diets, serum MCP-1 was significantly elevated compared with baseline (482.2 ± 174.2 pg/ml vs. 349.1 ± 163.2 pg/ml, respectively; p < 0.001; d = 0.79) and at the start of menopause (363.4 ± 117.2 pg/ml; p < 0.001; d = 0.80). Coronary VDR expression was inversely correlated with serum MCP-1 (p = 0.042). Additionally, the change of postmenopausal MCP-1 (from baseline to necropsy) was significantly reduced in the group with higher, compared to below the median, VDR expression (p = 0.038). The combination of plasma 25OHD3 and total plasma cholesterol/high-density lipoprotein cholesterol was subsequently broken into low-risk, moderate-risk and high-risk groups; as the risk increased, the VDR quantity decreased (p = 0.04). CAA was not associated with various atherogenic diets. CONCLUSION Coronary artery VDR expression was inversely correlated with markers of CAA risk and inflammation, including MCP-1, suggesting that systemic and perhaps local inflammation in the artery may be associated with reduced arterial VDR expression.

Abstract
An impaired blood-retinal barrier (BRB) leads to diabetic macular edema (DME), which is a major complication of Diabetic retinopathy (DR). Mediators such as inflammation cause BRB breakdown. However, the explicit mechanism of its disruption is largely unknown. In this study, we identified tumor necrosis factor ligand-related molecule 1A (TL1A) as a crucial factor which protect retinal endothelial cells integrity in DR. By providing both human and mouse data, we show that TL1A is significantly decreased in the retinas of DME patients and diabetic rodents. We further demonstrate that the loss of TL1A accelerated diabetes-induced retinal barrier breakdown. TL1A supplementation protects the diabetic retina against BRB breakdown. Mechanistically, TL1A stabilize intracellular junctions and protect vascular integrity by blocking SHP1-Src-regulated VE-cadherin phosphorylation. Collectively, our findings reveal that loss of TL1A in the retina leads to increased vascular permeability in DR, and that TL1A treatment is of potential therapeutic interest for the treatment of DME.

Abstract
Purpose: To investigate the incidence, characteristics, and risk factors of sports-related eye injuries among athletes in Tianjin, China. Methods: A cross-sectional study was carried out from March 2018 to October 2018. In this study, the athletes from Tianjin University of Sports, Tianjin Vocational College of Sports, and Tianjin provincial sports teams were selected for general investigation. In total, 1,673 athletes were invited and 1,413 participated in the study (response rate of 84.5%). Results: In total, 1,413 athletes were enrolled; 151 had suffered from sports-related eye injuries, with an incidence of 10.7% (95% CI: 9.1–12.0%). Handball (38.5%) was the sport with the highest incidence of eye injuries, followed by water polo (36.4%) and diving (26.7%). Overall, 42.4% of the athletes were injured by ball and 22.5% of injuries came from teammates. The eye injuries usually occurred during training (64.2%) and competitions (14.6%). Adnexa wound (51.7%) was the most common type of injury. About 11.9% of the athletes with eye injuries had the impaired vision; 66.7% failed to see doctors on time. The athletes <18 years of age had a higher risk of eye injuries (odds ratio [OR] =1.60, 95% CI: 1.06–2.40). The athletes with lower family income (<1,000 RMB) were at risk population for sports-related eye injuries (OR = 3.91, 95% CI: 2.24–6.82). Training >4 h a day increased the risk of eye injuries (OR = 2.21, 95% CI: 1.42–3.43). Conclusion: The incidence of sports-related eye injuries among athletes was 10.7% in Tianjin, China. Handball, water polo, and diving were the most common activities of injury. Age, family income, and training time were the risk factors for sports-related eye injuries.

Abstract
OBJECTIVE To investigate whether aryl hydrocarbon receptor (AhR) modulates cockroach allergen (CRE)-induced asthma by regulating Th17/Treg differentiation. OBJECTIVE Mouse models of CRE-induced asthma established by sensitizing and challenging the mice with CRE were randomized into asthma model group, AhR agonist group treated with TCDD (10 μg/ kg), and AhR antagonist group treated with TCDD and CH223191 (10 mg/kg) (n=5), with 5 mice without CRE challenge as the control group. The expressions of AhR, Cyp1a1 and Cyp1b1 mRNA in the lung tissues of the mice were detected using RT-PCR, and pulmonary inflammation was evaluated with immumohistochemical staining. The expressions of inflammatory cytokines in the lungs were detected using ELISA, and the expression of Treg in the lung tissues and pulmonary lymph nodes was analyzed with flow cytometry. OBJECTIVE Both TCDD and CH223191 were capable of modulating pulmonary expressions of AhR and its downstream genes Cyp1a1 and Cyp1b1 in asthmatic mice (P < 0.002). TCDD treatment significantly decreased inflammatory cells and mucus production in the lungs of asthmatic mice, and BALFs from TCDD-treated mice with CRE challenge contained lowered levels of the proinflammatory factors including IL-4, IL-13 and IL-17A (P < 0.001) but increased anti-inflammatory factors including IL-10, IL-22 and TGF-β1 (P < 0.001). All these changes were significantly reversed by treatment with CH223191 to the levels comparable with those in the asthma model group (P>0.05). More importantly, TCDD treatment significantly increased the number of Tregs cells and FOXP3 expression and lowered RORγt mRNA expression in the lungs and pulmonary lymph nodes in asthmatic mice (P < 0.001); inhibition of AhR with CH223191, as compared with TCDD, significantly decreased the expression of CD4+CD25+Foxp3+Treg cells in the lungs and pulmonary lymph nodes and the expression of FOXP3 mRNA in lymphocytes and increased RORγt mRNA expression (P < 0.001) to the levels comparable with those in asthma model group (P>0.05). OBJECTIVE AhR activation modulates airway inflammation in mice with CRE-induced asthma by modulating the differentiation of Th17/Treg.

Abstract
As advanced scenarios are developed for tokamak operations, the demand for flexibility of the electron cyclotron emission (ECE) channels' locations has increased. The tunable feature of yttrium iron garnet (YIG) filters provides this spatial flexibility. Here, we present a method of performing ECE measurements on fixed flux surfaces instead of fixed frequencies. This is achieved by adjusting YIG filters utilized in the intermediate frequency section to frequencies associated with flux surfaces in regions of interest during the discharge. The key components are the application of tunable YIG filters and a control program that calculates the filter settings using flux information from real-time reconstruction equilibria (EFIT). This fast procedure facilitates Te measurements in regions of interest to investigate plasma dynamic behaviors.

Abstract
PURPOSE To evaluate the factors related to sympathetic ophthalmia (SO) in a series of patients in our ophthalmology center and previously published cases. METHODS A retrospective and noncomparative review was performed on 16 patients with SO attending our ophthalmology center from 2013 to 2019. A total of 87 previously published cases of SO were identified by searching the Medline database from 2009 to 2019. RESULTS Sixteen patients were included in the analysis, and six cases were induced by transscleral cyclophotocoagulation (TCP). All patients had achieved controlled inflammation at their last follow-up visit. Thirteen patients (81.3%) had improved best-corrected visual acuity (BCVA). A review of the literature revealed 87 previously reported cases of SO. Shared clinical features and treatment outcomes were summarized. CONCLUSION Ocular therapies, including both penetrating ocular therapy and non-penetrating ocular intervention, have become increasingly prevalent risk factors for SO, and the latent period has increased compared to past reports. Visual prognosis with appropriate medical management is relatively good.

Abstract
BACKGROUND Postoperative pancreatic fistulae (POPF) are a major contributing factor to pancreatoduodenectomy-associated morbidity. Established risk calculators mostly rely on subjective or intraoperative assessments. We hypothesized that various objective preoperatively determined computed tomography (CT) measurements could predict POPF as well as validated models and allow for more informed operative consent in high-risk patients. METHODS Patients undergoing elective pancreatoduodenectomies between January 2013 and April 2018 were identified in a prospective database. Comparative statistical analyses and multivariable logistic regression models were generated to predict POPF development. Model performance was tested with receiver operating characteristics (ROC) curves. Pancreatic neck attenuation (Hounsfield units) was measured in triplicate by pancreatic protocol CT (venous phase, coronal plane) anterior to the portal vein. A pancreatic density index (PDI) was created to adjust for differences in contrast timing by dividing the mean of these measurements by the portal vein attenuation. Total areas of subcutaneous fat and skeletal muscle were calculated at the L3 vertebral level on axial CT. Pancreatic duct (PD) diameter was determined by CT. RESULTS In the study period 220 patients had elective pancreatoduodenectomies with 35 (16%) developing a POPF of any grade. Multivariable regression analysis revealed that demographics (age, sex, and race) were not associated with POPF, yet patients resected for pancreatic adenocarcinoma or chronic pancreatitis were less likely to develop a POPF (10 vs. 24%; p = 0.004). ROC curves were created using various combinations of gland texture, body mass index, skeletal muscle index, sarcopenia, PDI, PD diameter, and subcutaneous fat area indexed for height (SFI). A model replacing gland texture with SFI and PDI (AUC 0.844) had similar predictive performance as the established model (p = 0.169). CONCLUSION A combination of preoperative objective CT measurements can adequately predict POPF and is comparable to established models relying on subjective intraoperative variables. Validation in a larger dataset would allow for better preoperative stratification of high-risk patients and improve informed consent among this patient population.

Abstract
Tumour necrosis factor ligand related molecule 1 A (TL1A), a member of tumour necrosis factor superfamily, has been identified as a crucial regulator for vascular homeostasis and inflammation. However, the function of TL1A in diabetic retinopathy (DR) is largely unknown. This study aims to examine levels of TL1A in serum and intraocular fluid in patients with proliferative diabetic retinopathy (PDR), and to explore the correlation of intraocular TL1A with the prognosis of PDR progression after primary vitrectomy. Seventy-five patients (75 eyes) with PDR who underwent pars plana vitrectomy (PPV) and 19 patients (19 eyes) who received vitrectomy for idiopathic macular holes (IMH) as non-diabetic control group were enrolled in this prospective study. Serum, aqueous and vitreous fluid samples were collected during cataract and PPV surgery. Protein expressions of TL1A as well as other angiogenic and inflammatory cytokines in serum and intraocular fluid were measured. Correlations of intraocular TL1A concentrations with inflammatory cytokines were analyzed. We found both aqueous and vitreous TL1A levels were significantly higher in the PDR group than in control group (Paqueous = 0.026; Pvitreous <0.001). Angiogenic and inflammatory cytokines such as VEGF, IL-6, IL-8, MCP-1, MIP-1α, and MIP-1β were significantly higher in intraocular fluid in PDR group than in controls, which MCP-1 and MIP-1α showed positive correlation with intraocular TL1A levels. There is no significant difference in the levels of serum TL1A as well as other inflammatory cytokines between PDR patients and controls. Intraocular levels of TL1A were significantly lower in PDR progression group than in the stable group (Paqueous <0.001; Pvitreous <0.001). Multivariate logistic regression analyses revealed that lower levels of intraocular TL1A was an important risk factor for predicting PDR progression after primary PPV (ORaqueous = 0.717, Paqueous = 0.001; ORvitreous = 0.684; Pvitreous = 0.002). In conclusion, TL1A and multiple inflammatory cytokines were highly enriched in the intraocular fluid of PDR patients compared with the controls. Lower levels of intraocular TL1A were associated with development of PDR complications after primary PPV and might be used as prognostic factor in predicting the vitrectomy outcome in PDR patients.

Abstract
Objective: To compare and analyze the effect of minimally invasive surgery and traditional open surgery in patients with spinal canal tumors, including intraspinal and extraspinal communication tumors. Methods: From 2017 to 2019, 31 patients (minimally invasive channel group) were included in the neurosurgery department of Huashan Hospital Affiliated to Fudan University, and 38 patients (open operation group) were selected as the control group. From the aspects of intraoperative condition, operative effect, postoperative muscle injury, postoperative complications, postoperative spinal stability, the minimally invasive access group and the open operation group were compared and analyzed. Results: The bleeding volume (70.2 ml±4.9 ml), operation time (164.7 min±16.0 min) and hospitalization days (9.5±2.5) in the minimally invasive access group were significantly lower than those in the open operation group (P<0.001). The creatine kinase CK (363.9 U/L±51.6 U/L) in the minimally invasive group was significantly lower than that in the open group (514.2 U/L±68.3 U/L) (P<0.001). According to Panjabi standard, the effect of spinal cord stability in minimally invasive group was significantly lower than that in open operation group (P<0.001), and the symptom improvement rate in minimally invasive group was significantly higher than that in open hand group (P<0.05). Conclusions: Compared with the open surgery, the amount of bleeding, the length of incision, the time of operation and the days of hospitalization were significantly shorter, the degree of muscle damage was also significantly reduced, the incidence of complications was lower, the impact of spinal stability was smaller, and the overall advantage was obvious.

Abstract
PURPOSE Human telomerase reverse transcriptase (hTERT) and calcium-sensing receptor (CaSR) act as an oncogene in gastric cancers, however, their relationship in the progression of gastric cancers is yet to be elucidated. Herein, we aimed to access the potential interaction between hTERT and CaSR in the development of gastric cancers. METHODS The clinical data of 41 patients with gastric cancers were analyzed regarding the expressions of hTERT and CaSR by immunohistochemistry. Among them, five patients' specimens were also analyzed by Western blotting. The regulation of calcium on the expression level of hTERT and the possible underlying mechanism via CaSR were explored in gastric cancer cell lines MKN45 and SGC-7901. RESULTS Both hTERT and CaSR were increased and positively correlated in human gastric cancers, which also occurs in gastric cancer cells MKN45 and SGC-7901. Calcium induced hTERT expression at the transcriptional level in a CaSR-dependent manner followed by an increase in telomerase activity, as either a CaSR shRNA or the CaSR antagonist NPS2143 abolished the calcium-mediated regulation of hTERT and telomerase activity. Further studies showed that CaSR-mediated cytosolic calcium rise followed by Akt activation was involved in the regulation of hTERT by extracellular calcium. Finally, neither CaSR overexpression nor shRNA-mediated CaSR downregulation had an effect on the expression level of hTERT. CONCLUSIONS Our findings established a functional linkage between CaSR and hTERT in the development of gastric cancers and CaSR-hTERT coupling might serve as a novel target for therapeutic strategy against human gastric cancers.

Abstract
Abstract
BACKGROUND
Growth of glioma cells can be promoted by hypoxia, but its underlying molecular mechanisms are not clear. Exosomes and miRNAs were reported to play crucial roles in tumor progression. Effects of exosomes and exosomal miRNAs, induced by hypoxia, on glioma cells were still unclear.
MATERIAL AND METHODS
Glioma samples were analyzed by HE and HIF-1α staining. Image data of these patients were also retrospectively analyzed. HT22 and C6 cell lines were co-cultured in both direct and indirect system. Hypoxia (1% oxygen) and oxygen and glucose deprivation (OGD) were applied to evaluate hypoxia effects on the growth and proliferation of cell lines, and such effects were assessed by C6/HT22 ratio, MTT and LDH assay. Hypoxia-induced glioma derived exosomes (HIGDE) and non-HIGDE (NHIGDE) were isolated and were administrated to normal culture medium to evaluate their effects on cell growing. The target miRNA was selected by performing miRNA microarray analysis. MicroRNA mimics and shRNA were constructed to overexpress or inhibit the microRNA expression. MTOR signal pathway was activated by utilizing phosphatidic acid. The RNAs expression were detected by RT-qPCR and the proteins expression was evaluated by western blotting.
RESULTS
Para-tumor hypoxia area shared a same region with cytotoxic edema around the glioma lesion and can be easily detected by PET/CT. The density of positive HIF-1αstaining was higher in tumor area than that in para-tumor and normal parenchyma area. In hypoxia direct co-culture system, the cell number ratio of C6/HT22 was significantly higher than that without hypoxia pretreatment; while in hypoxia mono-culture and indirect co-culture systems, the proliferation ability of HT22 was statistical lower than C6. After applying OGD, neuron cells cultured with HIGDE showed a statistical higher LDH release level than with NHIGDE or normal culture medium. The miRNA microarray analysis revealed that miRNA-199a-3p was the highest expressed in HIGDE than in NHIGDE (p < 0.05; Fold Change > 2). Transfected with mimics or shRNA, it was indicated that upregulation of miR-199a-3p aggravated HIGDE-induced OGD injury in HT22 cells. Moreover, we interfered mTOR signal pathway and the expression of HIF-1αin C6 cells. We found that miRNA-199a-3p aggravated HIGDE-neuron cell injury via suppressing mTOR signal pathway, and hypoxia related upregulation of miRNA-199a-3p in HIGDE was induced by the activation of HIF-1α in C6 cells.
CONCLUSION
The Hypoxia-Induced Glioma Derived Exosome miRNA-199a-3p can be upregulated by the activation of HIF-1α, and is able to promote glioma cells proliferation and increase ischemic injury of the para-tumor neurons via inhibiting mTOR pathway.

Abstract
Objective: To investigate the prevalence, demographic characteristics and social life function of mental disorders in the rural left behind elderly aged 60 years and older in Gansu. Methods: Between November 2017 and June 2018, a multi-stage stratified cluster sampling method was used to randomly select the rural left behind elderly aged 60 years and older in Gansu, and totally 6 000 elderly were enrolled. By using the extended general health questionnaire (GHQ-12) and the American Handbook for Diagnosis and Statistics of Mental Disorders (DSM-Ⅳ) Axis Ⅰ Disorders Formal Clinical Examination Patient Edition, all the included subjects were screened and diagnosed. Functional status was assessed by the Global Assessment Function scale (GAF). Statistical analysis of the prevalence of various mental illnesses, as well as the differences in the prevalence of different gender, marital status and age groups was performed. Results: Totally, 6 000 subjects completed the survey. The adjusted current prevalence of any mental disorder was 20.11% (95%CI 17.70%-22.85%). The six most prevalent specific disorders were major depressive disorder (9.20%), pain disorder (2.71%), mood disorder due to the body condition (2.08%), generalized anxiety disorder (1.99%), anxiety disorder not otherwise specified (1.15%) and dysthymic disorder (0.84%). The lifetime prevalence of mental disorders was 20.54% (95%CI 18.40%-23.39%). The overall current prevalence of mental disorders was higher in women (242.89‰) than in men (119.55‰), and the unmarried (248.37‰) was higher than those married (187.53‰). There was no significant difference in the prevalence of mental disorders among different age groups (P>0.05). The GAF score of mental disorders was 56±11, and 71.82% was moderate to severe functional impairment. Conclusions: The prevalence of mental disorders is high in rural left-behind population aged 60 years and over in Gansu Province. Major depression is a condition that deserves special attention.

Abstract
This study aims to explore the correlation of hepatocyte growth factor (HGF) and fibroblast activation protein (FAP) expressions with the angiogenesis and metastasis in colorectal cancer (CRC). The immunohistochemical SABC method was used to detect HGF and FAP expressions in 127 CRC tissues, 51 colorectal polyp tissues and 28 normal tissues. HGF and FAP expressions in liver metastasis were detected using western blot to analyze the correlation of their expressions with lymph node metastasis and liver metastasis. Micro-vessel density (MVD) and clinic-pathologic information of CRC patients were recorded and analyzed. In CRC group, HGF and FAP expressions were greatly higher than those in normal group and colorectal polyps group (P < 0.05). Moreover, the positive rates of HGF and FAP expressions in lymph node metastasis were evidently higher than those in non-lymph node metastasis (P < 0.05). In liver metastasis group, HGF and FAP expressions were obviously higher than non-liver metastasis group (P < 0.05). CRC group had much more MVD in comparison with normal group and colorectal polyps group (P < 0.05).When compared with negative group, MVD was significantly higher than that in CRC tissue with positive HGF and FAP (P < 0.05). Spearman rank correlation analysis showed that HGF and FAP were in positive correlation with MVD (r = 0.542, P < 0.001; r = 0.753, P < 0.001). These results indicate that FAP and HGF play an important role in CRC angiogenesis, and their expression levels are valuable to predict CRC liver metastasis and lymph node metastasis.

Abstract
BACKGROUND Isoflurane is one of the most common general anaesthetics used during surgical procedures, including tumour resection. However, the effects of isoflurane on the viability and migration capacity of cancer cells, specifically in the context of brain cancer cells, remain unclear. Therefore, the aim of this study was to evaluate the influence that isoflurane has on the function of glioblastoma stem cells (GCSs) in regards to cell proliferation, survival and migration. METHOD U251-GSCs were exposed to isoflurane at clinically relevant concentrations and incubation times. The effects on proliferation, survival and migration capacities of the cells were evaluated in vitro. The potential risk was assessed in mice by intracranial injection of U251-GSCs pretreated with isoflurane. Furthermore, the average tumour volume and migration distance of U251-GSCs from the tumour centre were calculated. RESULTS Exposure of U251-GSCs to 1.2% isoflurane for 6 h resulted in increased proliferation (P<0.05) and decreased apoptosis rate (P<0.05) when compared with the control group. In addition, isoflurane exposure caused increased migration capacity in vitro (P<0.05) and the distance migrated was increased in vivo (P<0.05). CONCLUSION Clinically relevant concentrations and incubation times of isoflurane could promote the viability and mobility of U251-GSCs, suggesting this general anaesthetic may have detrimental effects in glioblastoma by facilitating its growth and migration.

OBJECTIVE A preliminary investigation on the proliferation and cultivation process of natural killer T cells (NKT) was carried out. We provide reference data for future NKT-related research and development. METHODS Peripheral blood mononuclear cells (PBMCs) were isolated from healthy people and were induced by α-galactosylceramide (α-GalCer). The phenotypic changes of the cells and the activation and apoptosis of Caspase-3 were recorded for 3-4 weeks. RESULTS The proliferation of the NKT cells continued for approximately 3 weeks, and then apoptosis started to occur. The activity of Caspase-3 was maintained at a high level from the second week. The responses of individual human NKT cells to α-GalCer stimulation differed significantly. CONCLUSION The proliferation of the NKT cells continued for approximately 3 weeks, and then apoptosis Semiconstitutively started to occur. The activity of Caspase-3 was maintained at a high level from the second week. The responses of individual human NKT cells to α-GalCer stimulation differed significantly.
