Abstract
Primary open‐angle glaucoma (POAG) is characterized by irreversible neurodegeneration accompanied by visual field defects and high intraocular pressure. Currently, an effective treatment is not available to prevent the progression of POAG, other than treatments to decrease the high intraocular pressure. We performed proteomic analysis of aqueous humour (AH) samples from patients with POAG combined with cataract and patients with cataract to obtain a better understanding of the pathogenesis of POAG and explore potential treatment targets for this condition. Samples were collected from 10 patients with POAG combined with cataract and 10 patients with cataract. Samples from each group were pooled. A high‐resolution, label‐free, liquid chromatography‐tandem mass spectrometry‐based quantitative proteomic analysis was performed. In total, 610 proteins were identified in human AH samples from the two groups. A total of 48 up‐regulated proteins and 49 down‐regulated proteins were identified in the POAG combined with cataract group compared with the control group. Gene Ontology (GO) analysis revealed key roles for these proteins in inflammation, immune responses, growth and development, cellular movement and vesicle‐mediated transport in the biological process category. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated the down‐regulated expression of glutathione S‐transferase P (GSTP1) in the glutathione metabolism signalling pathway in the POAG combined with cataract group. Additionally, certain significantly differentially expressed proteins in the proteomic profile were verified by enzyme‐linked immunosorbent assay (ELISA). GSTP1 levels were reduced in the human AH samples from the POAG combined with cataract group, based on the results of ELISA and proteomic profiling. Therefore, GSTP1, a redox‐related marker, may be involved in the pathological process of POAG and may become a treatment target in the future.

Abstract
Background: Glioma, the most common tumour in children next to leukaemia, is difficult to treat, with a poor prognosis and high recurrence rate. Xeroderma pigmentosum group G (XPG) plays a key role in the nucleotide excision repair pathway, which may modulate individual susceptibility to developing cancer. We hypothesized links between XPG variants and glioma in children.Methods: We tested our hypothesis in a study comparing 171 glioma cases with 228 age and sex matched controls, determining XPG polymorphisms rs2094258 C > T, rs751402 C > T, rs2296147 T > C, rs1047768 T > C, rs873601 G > A by standard molecular genetic methods.Results: rs2094258 C > T was associated with a decreased glioma risk, but carrying the rs1047768 C or rs873601 A allele brought an increased risk. Subjects carrying 5 risk genotypes had a significantly increased glioma risk at an adjusted odds ratio of 1.97 (95% confidence Interval 1.26-3.08)(p = 0.003) when compared with those carrying 0-4 risk genotypes. Furthermore, children with 5 risk genotypes had a higher glioma risk when aged >60 months, were more likely to be male, and with subtypes of astrocytic tumours, and low-grade clinical stage, when compared to those with 0-4 risk genotypes. Preliminary functional exploration suggested that rs2094258 is linked with the expression of its surrounding genes in the expression quantitative trait locus analysis.Conclusion: Certain variants of XPG are risk factors for paediatric glioma, and so may be useful in early diagnosis.

Abstract
Pneumoconiosis is an occupational lung disease that is mainly caused by diffuse fibrosis of lung tissue due to long-term inhalation of productive dust during occupational activities and retention in the lungs. Macrophages, epithelial cells and other cells can release a large number of cytokines, such as transforming growth factor-β, monocyte chemotactic protein-1, etc. These cytokines can participate in pathologies such as local injury, inflammatory response, and pulmonary fibrosis. This article reviews the role of cytokines in the pathogenesis of pneumoconiosis in order to provide a basis for further research.

Abstract
Objective: To explore the association between lifestyle-related factors and colorectal adenoma. Methods: Based on the Screening Project of Early Diagnosis and Treatment of Colorectal Cancer in Jiashan county Zhejiang province, from August 2012 to March 2018, information gathered through records on questionnaire and colonoscopic diagnosis were collected from participants with positive results during the primary screening stage. According to the findings of colonoscopy, 11 232 controls without any colorectal diseases and 3 895 cases with colorectal adenoma were included in the study. Multivariate logistic regression models were used to analyze the association between lifestyle-related factors and colorectal adenoma. Results: After adjusting for possible confounding factors, results from multivariate logistic regression analysis showed that smoking, alcohol drinking and obesity were positively related to the risk of colorectal adenoma, with ORs (95%CIs) as 1.38 (1.24-1.54), 1.37 (1.24-1.51) and 1.38 (1.20-1.59) respectively. However, regular aspirin intake was negatively related with the risk of colorectal adenoma (OR=0.65, 95%CI: 0.53-0.80). After stratified by sex and age, data showed that the associations between smoking, alcohol drinking and colorectal adenoma were statistically significant in males, and the association between regular aspirin intake and colorectal adenoma was also statistically significant in older participants (aged 60 years and older). Conclusion: Smoking, alcohol drinking, regular aspirin intake and obesity were associated with colorectal adenoma.

Abstract
BACKGROUND This study aimed to investigate the association between sugar in beverage and dementia, Alzheimer Disease (AD) dementia and stroke. METHODS This prospective cohort study were based on the US community-based Framingham Heart Study (FHS). Sugar in beverage was assessed between 1991 and 1995 (5th exam). Surveillance for incident events including dementia and stroke commenced at examination 9 through 2014 and continued for 15-20 years. RESULTS At baseline, a total of 1865 (63%) subjects consumed no sugar in beverage, whereas 525 (18%) subjects consumed it in 1-7 servings/week and 593 (29%) in over 7 servings/week. Over an average follow-up of 19 years in 1384 participants, there were 275 dementia events of which 73 were AD dementia. And 103 of 1831 participants occurred stroke during the follow-up nearly 16 years. After multivariate adjustments, individuals with the highest intakes of sugar in beverage had a higher risk of all dementia, AD dementia and stroke relative to individuals with no intakes, with HRs of 2.80(95%CI 2.24-3.50) for all dementia, 2.55(95%CI 1.55-4.18) for AD dementia, and 2.11(95%CI 1.48-3.00) for stroke. And the same results were shown in the subgroup for individuals with median intakes of sugar in beverage. CONCLUSION Higher consumption of sugar in beverage was associated with an increased risk of all dementia, AD dementia and stroke.

Abstract
AIMS With a goal to identify specific essential oils that can control postharvest Rhizopus rot on strawberry and peach fruits, we performed screening for 26 essential oils based on their antifungal activity against Rhizopus stolonifer in vitro and investigated the underlying mechanism. METHODS AND RESULTS Mentha spicata (Ms), Mentha piperita (Mp), Thymus vulgaris CT carvacrol (Tc) and Thymus vulgaris CT thymol (Tt) exhibited strong inhibition on R. stolonifer growth in the screening. These essential oils increased plasma membrane permeability of R. stolonifer and resulted in the outflow of intercellular electrolyte, nucleic acid, protein and soluble sugar. Morphology of R. stolonifer mycelia was greatly altered by these essential oils. Hyphae treated by these essential oils exhibited high accumulation of superoxide anion and malonaldehyde. Combination of these essential oils in commercial package reduced Rhizopus rot on strawberry and peach fruits, with Mp showing the strongest efficiency. CONCLUSION Ms, Mp, Tc and Tt essential oils inhibited R. stolonifer growth by targeting its plasma membrane and reduced Rhizopus rot on strawberry and peach fruits. SIGNIFICANCE AND IMPACT OF THE STUDY This study provides potential applications of natural plant extract, as alternatives to tradition fungicides, to control postharvest decay on fruits and vegetables.

Abstract
Objective: To evaluate the effect of intestinal carbapenem-resistant Enterobacteriaceae (CRE) active screening combined with enhanced intervention in the prevention and control of nosocomial infection in patients admitted to the hematological ward. Methods: Patients who were admitted to the Department of Hematology in a tertiary-care general hospital from March 1, 2017 to December 31, 2019 and underwent chemotherapy or immunosuppressive therapy comprised the intervention group. They were screened for intestinal CRE at least thrice. From December 1, 2016 to February 28, 2017, patients who underwent chemotherapy or immunosuppressive therapy without active intestinal CRE screening in the Department of Hematology formed the control group. Both the patient groups were monitored for CRE infection in real time. The χ(2) test was used to compare the changes in the CRE infection rate and mortality in high-risk patients before and after the active screening. Results: During the intervention period, the CRE colonization rate of patients was 16.46% (66/401) ; in terms of disease distribution, the colonization rate of acute leukemia was the highest 23.03% (26/113) . Of the 66 colonized patients, 27 (40.9%) patients were identified as positive for CRE at the first screening, 15 (22.7%) were identified at the time of the second screening, and the remaining 24 (36.4%) were identified at the third or subsequent screening; Carbapenem-resistant Klebsiella pneumoniae (CRPK) strains were dominant among the pathogens, accounting for 54.55% (36/66) . During the active screening period, the CRE infection rate (2.49%) and mortality rate (50.00%) of high-risk patients were significantly lower than those of the controls (11.30% and 69.23%, respectively) . The pathogens of 10 CRE infection patients during the intervention period were exactly the same as the previous active screening pathogens, and the coincidence rate was 100%. Conclusion: The CRE colonization rate was the highest in patients with acute leukemia who were admitted in the hematology wards. CRPK is the main pathogen of CRE colonization, infection, and death. Increasing the frequency of screening can significantly raise the positive rate of screening, Active screening can effectively reduce the incidence and subsequent mortality of CRE in high-risk patients admitted in the hematological wards. High coincidence rate between CRE screening positive pathogens and subsequent CRE infection pathogens. Intestinal CRE screening can serve as an indicator of CRE bloodstream infection in patients with hematological diseases as well as provide information for antibiotics therapy.

Abstract
GABAergic circuits are critical for the synchronization and higher order function of brain networks. Defects in this circuitry are linked to neuropsychiatric diseases, including bipolar disorder, schizophrenia, and autism. Work in cultured neurons has shown that ankyrin-G plays a key role in the regulation of GABAergic synapses on the axon initial segment and somatodendritic domain of pyramidal neurons, where it interacts directly with the GABAA receptor-associated protein (GABARAP) to stabilize cell surface GABAA receptors. Here, we generated a knock-in mouse model expressing a mutation that abolishes the ankyrin-G/GABARAP interaction (Ank3 W1989R) to understand how ankyrin-G and GABARAP regulate GABAergic circuitry in vivo. We found that Ank3 W1989R mice exhibit a striking reduction in forebrain GABAergic synapses resulting in pyramidal cell hyperexcitability and disruptions in network synchronization. In addition, we identified changes in pyramidal cell dendritic spines and axon initial segments consistent with compensation for hyperexcitability. Finally, we identified the ANK3 W1989R variant in a family with bipolar disorder, suggesting a potential role of this variant in disease. Our results highlight the importance of ankyrin-G in regulating forebrain circuitry and provide novel insights into how ANK3 loss-of-function variants may contribute to human disease.

Abstract
Objective: To explore the influencing factors of job burnout of medical staff and provide reference for the formulation of intervention measures. Methods: From November to December, 2018, a questionnaire survey was conducted among medical staff in a general hospital by using the research design of the current situation survey. A total of 1193 questionnaires were distributed and 939 questionnaires were returned, with a recovery rate of 78.7%, including 891 valid questionnaires and an effective recovery rate of 94.9%. Social support rating scale (SSRs) was used to evaluate social support, and Maslach Burnout Scale (MBI-GS) was used to evaluate job burnout. Single factor analysis was performed by chi square test and Fisher exact probability method. To explore the influencing factors of job burnout by using disordered multi classification logistic. Results: The average age was (27.47 ± 4.22) years old, female accounted for 71.5% (637/891) . The total physical examination rate of job burnout was 46.6%. The scores of emotional exhaustion, cynicism and decreased sense of achievement were (10.10±3.75) , (6.14±3.43) , (17.91±4.13) respectively. Multiple logistic regression analysis showed that, compared with the non detected job burnout, the young, working for 1-3 years, average sleep ≤6 hours, and poor social support were more likely to have mild job burnout (OR=0.91, 0.40, 2.25, 2.38, P<0.05) ; female, high night shift frequency in the past year, average sleep ≤6 h. Those with poor social support were more likely to have moderate to severe job burnout (OR=1.59, 2.94, 4.01, 2.40, 3.66, P<0.05) . Conclusion: Corresponding measures should be taken to reduce job burnout and improve work efficiency.

Abstract
OBJECTIVES Enteral formula delivery strategy is an important part of enteral nutrition. We aimed to synthesize up-to-date studies to clarify the effects of intermittent versus continuous feeding on feeding intolerance during enteral nutrition in critically ill adults. DESIGN A meta-analysis of randomized controlled trials. DATA SOURCES Embase, PubMed, Information Sciences Institute Web of Science, CINAHL EBSCO, Cochrane Central Register of Controlled Trials, Chinese Biomedical Literature Database, China National Knowledge Infrastructure databases were searched from inception to 17th of June 2020. REVIEW METHODS The Cochrane "risk of bias" tool was used to assess the quality of individual studies, and the quality of each outcome was assessed by GRADE approach. Fixed or random effect meta-analysis was used pending the presence of heterogeneity. Dichotomous data synthesis was presented as risk ratio and 95% confidence interval, and quantitative data synthesis was shown as mean difference and 95% confidence interval. RESULTS Fourteen trials with 1025 critically ill adults were included in the meta-analysis. We found that intermittent feeding could significantly increase the occurrence of feeding intolerance (risk ratio = 1.64, 95% confidence interval = 1.23 to 2.18, P < 0.001) compared with continuous feeding, as well as the incidence of high gastric volume (risk ratio = 3.62, 95% confidence interval = 1.43-9.12, P = 0.006) and aspiration (risk ratio = 3.29, 95% confidence interval = 1.18-9.16, P = 0.02) in > 1-week trial duration, while constipation rate was reduced in intermittent feeding group (risk ratio = 0.66, 95% confidence interval = 0.45-0.98, P = 0.04). Patients in intermittent feeding group received more calories compared with continuous feeding group (mean difference = 184.81, 95% confidence interval = 56.61-313.01, P = 0.005). The quality of all evidence synthesis was "low" or "very low". CONCLUSIONS In critically ill adults, continuous feeding was associated with lower overall incidence of feeding intolerance, especially in high gastric volume and aspiration. However, decreased constipation incidence and more calorie intake were observed in intermittent feeding group. Because quality of the synthesized evidence was "low" or "very low", there is considerable uncertainty about this estimate.

Abstract
OBJECTIVE Melanoma is regarded as one common malignancy in skin cancers, and there is growing evidence that microRNAs (miRNAs) play a vital role in the oncogenesis of tumors. This study aimed to investigate the roles and mechanism of miR-22 in melanoma. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was utilized to detect the expressions of miR-22 and mRNA. The functions of miR-22 in melanoma cell proliferation, migration and invasion were investigated with functional assays, including MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) and transwell assay. Western blots were utilized to examine the protein expressions. Luciferase reporter analysis was conducted to confirm the interactions between formin-like 2 (FMNL2) and miR-22 in melanoma cells. FMNL2 expression levels in melanoma tissues were investigated by immunohistochemistry (IHC) assays. RESULTS The qRT-PCR analysis demonstrated significant decreased miR-22 expressions in melanoma tissues. Decreased miR-22 in melanoma tissues were correlated with adverse clinicopathologic features and poor prognosis. Functional assays indicated that upregulation inhibited melanoma cell proliferation, invasion and migration capacities. Luciferase reporter assays showed that FMNL2 was targeted by miR-22 in melanoma cells. Western blots indicated that miR-22 exerted anti-tumor functions by regulating the Wnt/β-catenin and epithelial-mesenchymal transition (EMT). CONCLUSIONS Our findings showed that miR-22 served as a tumor suppressor in melanoma progression, implying that miR-22 may function as a novel therapeutic target and prognostic biomarker for melanoma treatments.

Abstract
OBJECTIVE The aim of this study was to clarify the function of long noncoding ribonucleic acids (lncRNAs) small nucleolar RNA host gene 7 (SNHG7) in cisplatin-resistant non-small cell lung cancer (NSCLC), and to explore the potential mechanism. PATIENTS AND METHODS SNHG7 expression in NSCLC and para-cancerous tissues was determined by quantitative real-time polymerase chain reaction (qRT-PCR). Meanwhile, the correlation between SNHG7 expression with clinical stage and cisplatin-resistance in NSCLC patients was analyzed. After transfection of si-SNHG7 or p-complementary deoxyribonucleic acid (pcDNA)-SNHG7, changes in cellular behaviors of A549/DDP cells were evaluated, including cell viability, apoptosis, migration, invasion and cell cycle. The regulatory effects of SNHG7 on the expressions of genes were determined by qRT-PCR as well. Furthermore, Western blot was conducted to determine the protein expressions of drug-resistance genes minimal residual disease1 (MRD1), P-glycoprotein (P-gp), BCRP and relative genes in phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) pathway. RESULTS Compared with adjacent normal tissues, SNHG7 was highly expressed in NSCLC tissues. Moreover, SNHG7 expression was significantly higher in advanced-stage NSCLC patients than those in early-stage. SNHG7 level remained significantly higher in DDP-resistant NSCLC tissues and cell lines as well. Knockdown of SNHG7 remarkably enhanced cisplatin-resistance in NSCLC cells, manifesting as decreased cell viability, migratory and invasive rates, DNA synthesis capacity, and promoted apoptosis. Meanwhile, SNHG7 knockdown down-regulated the mRNA levels of matrix metalloprotein2 (MMP2), MMP7 and MMP9 in vitro. After SNHG7 knockdown, the expressions of drug-resistant and relative genes in the PI3K/AKT pathway were notably down-regulated. CONCLUSIONS SNHG7 induces the development of cisplatin-resistance in NSCLC through upregulating MRD1 and BCRP via PI3K/AKT pathway.

Abstract
Owing to the experimental discovery of magnetic skyrmions stabilized by the Dzyaloshinskii-Moriya and/or dipolar interactions in thin films, there is a recent upsurge of interest in magnetic skyrmions with antiferromagnetic spins in order to overcome the fundamental limitations inherent with skyrmions in ferromagnetic materials. Here, we report on the observation of compact ferrimagnetic skyrmions for the class of amorphous alloys consisting of 4f rare-earth and 3d transition-metal elements with perpendicular magnetic anisotropy, using a DyCo3 film, that are identified by combining X-ray magnetic scattering, scanning transmission X-ray microscopy, and Hall transport technique. These skyrmions, with antiparallel aligned Dy and Co magnetic moments and a characteristic core radius of about 40 nm, are formed during the nucleation and annihilation of the magnetic maze-like domain pattern exhibiting a topological Hall effect contribution. Our findings provide a promising route for fundamental research in the field of ferrimagnetic/antiferromagnetic spintronics towards practical applications.
