Abstract
Fusarium graminearum is an important soybean pathogen that causes seedling disease, root rot, and pre- and postemergence damping-off. However, effects of soil conditions on the disease are not well understood. The objective of this greenhouse study was to determine the impacts of soil texture, pH, and soil moisture on seedling root rot symptoms and detrimental effects on seedling development caused by F. graminearum. F. graminearum-infested millet was added (10%, vol/vol) to soil with four different textures (sand, loamy sand, sandy loam, and loam). Soil moisture was maintained at saturation, field capacity or permanent wilting point at soil pH levels of 6 or 8. Seedlings were evaluated 4 weeks after planting for root rot, root length, root and shoot dry weights, leaf area, and F. graminearum colonization (by qPCR). There was a significant interaction between soil moisture and soil texture for root rot assessed visually (P < 0.0001). Highest severity (67%) and amount of F. graminearum DNA were observed at pH 6 and permanent wilting point in sandy loam soils. Pot saturation resulted in the lowest levels of disease in sandy loam and loam soils (11.6 and 10.8%, respectively). Reductions in seedling growth parameters, including root length, foliar area, shoot and root dry weights, and root tips, relative to the noninfested control, were significantly greater in sandy loam soils. In contrast, there were no significant growth reductions in sand. This study showed that levels of root rot increased under moisture-limiting conditions, producing detrimental effects on plant development.

Abstract
OBJECTIVE This study was designed to investigate whether microRNA-1297 can regulate the osteogenesis of bone marrow mesenchymal stem cells (BMSCs) through WNT5A, thus influencing the progression of osteoporosis. PATIENTS AND METHODS Quantitative Real-time polymerase chain reaction (qRT-PCR) assay was performed to analyze microRNA-1297 level and osteogenesis-related markers in osteoporosis patients and controls. The protein levels of the above markers and WNT5A were detected by Western blot. Alkaline phosphatase (ALP) activity assay and ALP staining were used to measure the degree of osteogenic differentiation under the control of microRNA-1297 and WNT5A, and ARS staining was used to detect the mineralization ability of hBMSC after overexpression of microRNA-1297. The binding sites of microRNA-1297 and WNT5A were determined by the dual luciferase-reporting assay. Besides, the activity of Wnt signal transduction pathway in different treatment groups was detected by TOP/FOP report. RESULTS MicroRNA-1297 was highly expressed in osteoporotic patients, and its level decreased significantly with the increasing of osteogenic induction. Bioinformatics prediction suggested that microRNA-1297 can target WNT5A. In vitro experiments showed that overexpression of microRNA-1297 in hBMSC can reduce the level of WNT5A, while interference with microRNA-1297 can increase the level of WNT5A. Overexpression of microRNA-1297 and transfection of si-WNT5A significantly reduced the mRNA levels of RUNX2, OSX, ALP, OCN, OPN and COL1A1, thereby inhibiting osteogenic differentiation. Overexpression of microRNA-1297 could interfere with WNT signaling pathway regulation and regulate the osteogenic differentiation of hBMSCs. CONCLUSIONS microRNA-1297 could regulate the osteogenesis of BMSCs by combining with WNT5A so as to accelerate the progression of osteoporosis.

Abstract
BACKGROUND Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma have poorer outcomes after functional endoscopic sinus surgery (FESS) and higher recurrence rate. The aim of present study was to investigate the long-term clinical outcomes of extended surgical strategies for patients with recurrent CRSwNP and asthma. METHODS Eighty-one patients with CRSwNP and asthma were enrolled in this 5-year prospective study. They were randomly assigned to undergo FESS, radical endoscopic sinus surgery (RESS), or RESS+Draf 3 surgery. Disease severity and clinical outcomes were evaluated using symptoms scoring, endoscopic scoring system, computed tomography staging system, sinus-specific quality of life scores, tissue and peripheral blood eosinophil percentage, and pulmonary function tests. Baseline, 1-year, 3-year, and 5-year follow-up data were compared among the groups. RESULTS RESS and RESS+Draf 3 strategies yielded better short-term (1 year) outcomes than did FESS. FESS had a higher short-term recurrence rate, although recurrence rates were similarly high (95.6 - 96.1%) in all the groups at 5 years postoperatively. RESS and RESS+Draf 3 yielded a lower long-term revision surgery rate and a longer time to recurrence post-surgery than FESS, which was negatively correlated with tissue and peripheral blood eosinophil percentage. CONCLUSIONS CRSwNP with asthma is a systemic disease that inevitably recurs. Radical surgery prolongs recurrence time and improves olfaction, rhinorrhea, and quality of life in the short-term. Combining Draf 3 with RESS did not yield better clinical outcomes than RESS alone; thus, although RESS alone appears to be the best option, these findings need to be confirmed in further studies involving more patients, longer follow-up duration and stricter standardized medication use especially the adequate steroid irrigations.

Abstract
Objective: To analyze the epidemiological characteristics of human brucellosis (HB), evolution and origin feature of Brucella strains in Tongliao city, Inner Mongolia Autonomous Region during 2004-2018, and to provide evidence for strategy development against the disease. Methods: Data from the reports on HB in Tongliao during 2004-2018 were extracted from the China Information System for Disease Control and Prevention before being analyzed with software Excel 2016. Epidemiologic feature was described, using the number of cases, constituent ratio and related rates. Conventional biotypes methods were used for identification of species/biovars strains while species of six Brucella strains were further verified by AMOS-PCR. Cluster analyze on six Brucella strains were performed with Bio-Numerics 5.0 software and for examining and revealing the genetic characteristics of the related strains. Results: During 2004-2018, a total of 16 704 HB cases were reported, with the incidence rate as 35.41/100 000. The incidence rates appeared as 110.51/100 000 in Jarud Banner and 67.84/100 000 in Kulun flag, which were both higher than the other areas. Most of the cases were reported in the 40-54 year olds, which accounted for 48.75% (8 143/16 704). The number of HB in farmers appeared as 14 873, which counted for 89.04% (14 873/16 704) of all the cases. Male to female ratio of incidence was 2.40∶1. Most of the reported cases appeared between March to May, which accounted for 56.30% (9 405/16 704). Peak of the disease was seen in April. Using the conventional identification method, results showed that the available six strains all belonged to B. melitensis, including three of them as B. melitensis bv.1 and others three strains as B. melitensis bv. 3. Results from the amplified AMOS-PCR showed that all the strains were B. melitensis. The six strains clustered in two MLVA-11 genotypes (111 and 116) and all belonged to the Eastern Mediterranean lineage. Based on the MLVA-16 cluster analysis, results suggested that strains from this study were having close genetic relationship with B. melitensis strains that were from Jilin and Heilongjiang provinces. Conclusions: Human brucellosis identified in Tongliao area was with greater risk in spreading the disease to the vicinity. Our findings indicated that the programs on detection and control of the disease should be strengthened.

Abstract
Searches for electron antineutrino, muon neutrino, and muon antineutrino disappearance driven by sterile neutrino mixing have been carried out by the Daya Bay and MINOS+ collaborations. This Letter presents the combined results of these searches, along with exclusion results from the Bugey-3 reactor experiment, framed in a minimally extended four-neutrino scenario. Significantly improved constraints on the θ_{μe} mixing angle are derived that constitute the most constraining limits to date over five orders of magnitude in the mass-squared splitting Δm_{41}^{2}, excluding the 90% C.L. sterile-neutrino parameter space allowed by the LSND and MiniBooNE observations at 90% CL_{s} for Δm_{41}^{2}<13 eV^{2}. Furthermore, the LSND and MiniBooNE 99% C.L. allowed regions are excluded at 99% CL_{s} for Δm_{41}^{2}<1.6 eV^{2}.

Abstract
Single particle-resolved fluorescence imaging is an enabling technology in cold-atom physics. However, so far, this technique has not been available for nanophotonic atom-light interfaces. Here, we image single atoms that are trapped and optically interfaced using an optical nanofiber. Near-resonant light is scattered off the atoms and imaged while counteracting heating mechanisms via degenerate Raman cooling. We detect trapped atoms within 150 ms and record image sequences of given atoms. Building on our technique, we perform two experiments which are conditioned on the number and position of the nanofiber-trapped atoms. We measure the transmission of nanofiber-guided resonant light and verify its exponential scaling in the few-atom limit, in accordance with Beer-Lambert's law. Moreover, depending on the interatomic distance, we observe interference of the fields that two simultaneously trapped atoms emit into the nanofiber. The demonstrated technique enables postselection and possible feedback schemes and thereby opens the road toward a new generation of experiments in quantum nanophotonics.

Abstract
Objective: To retrospectively analyze the clinical efficacy, safety and the main factors affecting the prognosis of anlotinib hydrochloride in the treatment of advanced primary liver cancer. Methods: Fifty-five cases with advanced primary liver cancer who received anlotinib hydrochloride were enrolled. The baseline data of the patients, such as prothrombin time, total bilirubin, albumin, Child-Pugh score, procalcitonin, alpha fetoprotein, extrahepatic metastasis, cirrhosis, portal hypertension, whether or not combined surgery, pathological staging, etc before treatment were recorded. Hematological and imaging results of the patients were reviewed. Adverse events that appeared in patients at any time until the end of follow-up or loss- to- follow-up or death were recorded. The survival curve was plotted by Kaplan-Meier method, and the difference of survival time between groups was examined by log-rank test. Cox regression model of single and multiple factor were used to analyze the factors affecting the prognosis. Results: As of the last follow-up, 2 patients were lost-to-follow-up, 30 died, and 23 survived. The median survival time was 6.5 months (196 days). Grade 3 or higher adverse events included hypertension (12.73%), leukopenia (3.64%), absolute neutropenia (1.82%), thrombocytopenia (9.09%), fatigue (3.64%), anemia (1.82%), and diarrhea (1.82%). Adverse events were effectively controlled. One case had fatal ruptured esophageal varices, which were not medically related. Multivariate Cox regression analysis showed that total bilirubin (HR = 0.247, P = 0.003), albumin (HR = 0.279, P = 0.003) and procalcitonin (HR = 0.105, P = 0.012) were independent factors affecting the prognosis of advanced HCC. Conclusion: Anlotinib hydrochloride therapy is safe, effective and well tolerated in patients with advanced liver cancer, and total bilirubin, albumin, and procalcitonin are independent factors that affect the prognosis of patients with advanced liver cancer.

Abstract
BACKGROUND At present, the severity of patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a focal point. METHODS To assess the factors associated with severity and prognosis of patients infected with SARS-CoV-2, we retrospectively investigated the clinical, imaging and laboratory characteristics of confirmed 280 cases of novel coronavirus disease (COVID-19) from 20 January to 20 February 2020. RESULTS The median age of patients in the mild group was 37.55 years, whilst that in the severe group was 63.04 years. The proportion of patients aged over 65 years in the severe group was significantly higher than that of the mild group (59.04% vs. 10.15%, P < 0.05). 85.54% of severe patients had diabetes or cardiovascular diseases, which was significantly higher than that of the mild group (51.81% vs. 7.11%, P = 0.025; 33.73% vs. 3.05%, P = 0.042). Patients in the mild group experienced earlier initiation of antiviral treatment (1.19 ± 0.45 vs. 2.65 ± 1.06 days in the severe group, P < 0.001). Our study showed that comorbidity, time from illness onset to antiviral treatment and age >=65 were three major risk factors for COVID-19 progression, whilst comorbidity and time from illness onset to antiviral treatment were two major risk factors for COVID-19 recovery. CONCLUSIONS The elderly and patients with underlying diseases are more likely to experience a severe progression of COVID-19. It is recommended that timely antiviral treatment should be initiated to slow the disease progression and improve the prognosis.

Abstract
OBJECTIVE To investigate the expression levels of T follicular helper (Tfh) with different subsets in patients with rheumatoid arthritis (RA) and their serum interleukin-6 (IL-6), interleukin-17 (IL-17), transforming growth factor-β (TGF-β) and matrix metalloproteinase 3 (MMP-3) contents. PATIENTS AND METHODS The medical records of 45 RA patients in the Department of Rheumatology and Immunology in the First Affiliated Hospital of Chengdu Medical College from January 2016 to April 2018 were retrospectively analyzed. They were divided into the RA high activity group (24 cases, group A) (DAS28 score ≥ 5.0) and RA low activity group (21 cases, group B) (3.2 < DAS28 score < 5.0). At the same time, 20 healthy subjects were selected as a control group. Flow cytometry was used to detect the expression levels of Tfh1, Tfh2 and Tfh17, enzyme-linked immunosorbent assay to detect serum IL-6, IL-17, IL-21 and MMP-3 concentrations. The correlation of Tfh cells with IL-6, IL-17, IL-21 and MMP-3 was analyzed. RESULTS Those of peripheral blood mononuclear cell (PBMC) Tfh2 and Tfh17 cells were significantly higher in group A than those in group B (p < 0.05). Compared with the control group, the concentrations of serum IL-6, IL-17 and MMP-3 significantly increased (p < 0.001), but that of serum TGF-β markedly decreased in group A and group B (p < 0.01). The concentrations of serum IL-6, IL-17 and MMP-3 were remarkably higher in group A than those in group B (p < 0.001), but that of serum TGF-β was significantly lower in group A than that in group B (p < 0.001). The expression level of PBMC Tfh2 cells, PBMC Tfh17 cells was positively correlated with serum IL-6, IL-17 and MMP-3. The expression levels of Tfh2 and Tfh17 cells are positively correlated with serum IL-6, IL-17 and MMP-3 concentrations, negatively correlated with serum TGF-β concentration. CONCLUSIONS Tfh2 and Tfh17 are expected to be new targets for immunotherapy in RA patients.

Abstract
Objective: To investigate the expression of CD8(+)CD25(+)T cells in peripheral blood of patients with rheumatoid arthritis (RA) and its correlation with clinical indicators of rheumatoid arthritis. Methods: Peripheral blood was collected from 38 patients with RA, and 20 healthy control subjects, RA patients admitted to Peking University people's hospital from May to October 2018, and record the RA patients with the clinical manifestations and laboratory indexes, extraction in the peripheral blood lymphocytes, using flow cytometry to analyse the percentage of CD8(+)CD25(+)T cells in peripheral blood, by using the software SPASS20 and Prism6 to analyze its correlation with clinical and laboratory indices. Results: The expression of CD8(+)CD25(+)T cells in peripheral blood of RA patients was significantly increased, which was statistically different from that of healthy patients (P<0.05). CD8(+)CD25(+)T cells in peripheral blood of RA patients showed significant positive correlation with ESR(r=0.352,P=0.030), CCP(r=0.312,P=0.047) and DAS28(r=0.330,P=0.043), and negatively correlated with C3 (r=-0.354,P=0.046) and C4(r=-0.440,P=0.010).No significant correlation was found in other indicators. In RA patients, there were statistically significant differences in CD8(+)CD25(+)T cells between the low-disease active group and the high-disease active group(P<0.05), but CD8(+)CD25(+)T cells between the low-disease active group and the moderate-disease active group, or between the moderate-disease active group and the high-disease active group had no significant statistical difference. Conclusion: CD8(+)CD25(+)Tcells in peripheral blood of patients with RA are significantlyincreased, and aresignificantly correlated with laboratory and clinical indicators, which may play an important role in the pathogenesis of rheumatoid arthritis.

Abstract
Many lncRNAs have been reported to affect cerebral ischemia/reperfusion (I/R) injury. The purpose of this study is to elucidate the role of lncRNA NEAT1 as well as the regulatory mechanism of lncRNA NEAT1/miR-874-3p in cerebral I/R injury. A cellular model of cerebral I/R injury was built. RT-qPCR was used to detect NEAT1 and miR-874-3p expression. Cell viability was detected by MTT assay. The expression of apoptosis-related proteins (Bcl-2 and Bax) was measured by Western blot analysis. The relationship between NEAT1 and miR-874-3p was confirmed by dual luciferase reporter assay. We found that LncRNA NEAT1 was upregulated in the PC12 cells treated by I/R and upregulation of lncRNA NEAT1 can aggravate I/R injury of PC12 cells. Additionally, lncRNA NEAT1 overexpression decreased cell viability and induced apoptosis in PC12 cells treated by I/R. Furthermore, miR-874-3p was confirmed to be a target of lncRNA NEAT1. mR-874-3p and NEAT1 expression are found to be reciprocally inhibited in PC12 cells. In summary, LncRNA NEAT1 aggravates cerebral I/R injury by suppressing miR-874-3p expression.

Abstract
The purpose of this study was to evaluate the ability of Lactobacillus rhamnosus to bind patulin (PAT) in the buffer solution and apple juice. The binding of L. rhamnosus to PAT was reversible, which improved the stability of the bacterial complex. The ability to bind PAT can be enhanced with the inactivation of the strain by high temperature and acid treatment. Acid-treated bacteria had the highest PAT binding rate of 72.73±1.05%. The binding rates of acid and high temperature (121 °C) treatments were increased by 21.37% and 19.15%, respectively. L. rhamnosus showed the best detoxification ability to PAT at 37 °C, where the binding rate reached 50.9±1.03%. When the dose of inactivated bacteria powder was 0.02 g ml−1, the minimum concentration of PAT in apple juice was 0.37 µg ml−1. The addition of the L. rhamnosus inactivated powder did not affect the quality of the juice product and effectively bound the PAT in apple juice.

Abstract
Objective: To investigate the impact of implant height on the morphology of cervical facet joints in artificial cervical disc replacement (ACDR). Methods: A finite element model of the cervical spine from C(2) to C(7) was constructed. The surgical processes of ACDR were simulated by insertion of 5 mm, 6 mm or 7 mm Prestige-LP artificial cervical discs. The morphological changes of cervical facet joints were recorded in terms of facet overlap distance, facet overlap area and facet angle. Results: The normal height Prestige-LP cervical disc could restore the natural status of the cervical spine. Compared with the intact condition, the model with ≥2 mm height implant would reduce the overall range of motion (ROM) by 19.2% in flexion, 19.4% in extension, 18.4% in lateral bending and 19.0% in axial rotation. Besides, the ROM at the surgical level reduced by 15.8% in flexion, 15.4% in extension and lateral bending and 19.0% in rotation. The upper and lower adjacent levels (C(4/5) and C(5/6)) showed more obvious changes in ROM, which reduced by 26.8% and 26.5% in flexion, 26.6% in extension, 26.5% and 26.4% in lateral bending, and 26.4% and 26.3% in rotation, respectively. The reduction of facet overlap distance, facet angle and facet overlap area with the ≥2 mm height artifact was 9.6%, 30.7%, and 17.9% respectively at the upper adjacent level, and 22.3%, 35.3% and 28.2% respectively at the surgical level, compared with the intact model.The morphology of facet joints at the lower adjacent level were slightly changed. Conclusion: The implant height selection in ACDR should be in accordance with the physiological intervertebral disc height. Artifact with ≥2 mm in height would obviously change the morphology of facet joints, thus should not be used in clinical practice.

Abstract
Environmentally persistent free radicals (EPFRs) are a new class of pollutants that are long-lived in fine particles (PM2.5), i.e., their 1/e lifetime ranges from days to months (or even infinite). They are capable of producing harmful reactive oxygen species such as hydroxyl radicals. The redox cycling of EPFRs is considered as an important pathway for PM2.5 to induce oxidative stress inside the humans, causing adverse health effects such as respiratory and cardiovascular diseases. Consequently, research regarding their toxicity, formation and environmental occurrences in PM2.5 has attracted increasing attentions globally during the past two decades. However, literature data in this field remain quite limited and discrete. Hence, an extensive review is urgently needed to summarize the current understanding of this topic. In this work, we systematically reviewed the analytical methods and environmental occurrences, e.g., types, concentrations, and decay behaviors, as well as possible sources of EPFRs in PM2.5. The types of pretreatment methods, g-values of common EPFRs and categories of decay processes were discussed in detail. Moreover, great efforts were made to revisit the original data of the published works of EPFRs in airborne particulate matter and provided additional useful information for comparison where possible, e.g., their mean and standard deviation of g-values, line widths (ΔH p-p), and concentrations. Finally, possible research opportunities were highlighted to further advance our knowledge of this emerging issue.

Abstract
OBJECTIVE To explore the role of microRNA-15b in diabetic retinopathy (DR) and its underlying mechanism. MATERIALS AND METHODS Diabetic retinopathy rat model was first constructed. Retinal endothelial cells (EC) and retinal pericytes (RP) in DR rats were extracted. The mRNA expression of microRNA-15b in EC and RP cells was detected by qRT-PCR (quantitative Real Time-Polymerase Chain Reaction). Protein expression of insulin receptor substrate 1 (IRS-1) in EC and RP cells was detected by Western blot. After altering microRNA-15b expression by plasmid transfection, cell viability was detected by CCK-8 (cell counting kit-8) assay. Furthermore, the target gene of microRNA-15b was predicted by TargetScan analysis and the binding condition was verified by luciferase reporter gene assay. Finally, rescue experiments were carried out to explore the regulatory effect of microRNA-15b on IRS-1. RESULTS MicroRNA-15b was lowly expressed, whereas IRS-1 was highly expressed in EC and RP cells. After overexpression of microRNA-15b, viabilities of EC and RP cells were decreased and β-catenin expression was inhibited. TargetScan predicted that IRS-1 was the downstream gene of microRNA-15b, which was further verified by luciferase reporter gene assay. Rescue experiments indicated that microRNA-15b was capable of regulating IRS-1 via Wnt/β-catenin signaling pathway. CONCLUSIONS MicroRNA-15b participates in the development of diabetic retinopathy by targeting IRS-1 via Wnt/β-catenin signaling pathway.

Abstract
BACKGROUND The diagnostic value of serum specific Immunoglobulin E (sIgE) and nasal allergen provocation test (NAPT) has been well investigated in local allergic rhinitis (LAR). We hypothesized that nasal local sIgE could be used for the diagnosis of LAR instead of NAPT. METHODS This was a prospective single center study. Overall, 212 chronic rhinitis patients were screened, of whom 73 were recruited based on negative findings for serum IgE and positive findings for local eosinophils. Ten healthy subjects were also recruited as controls. All participants completed questionnaires at recruitment to record their demographic data, nasal symptom severity, and physician-diagnosed comorbid asthma. Symptom severity was recorded using a visual analogue scale (VAS) of 10 cm and allergic status was assessed by serum sIgE. Nasal secretions were collected for analysis of local sIgE and eosinophils, and NAPT was performed for confirmation of LAR. RESULTS Overall, 14 patients demonstrated positive local sIgE results. Twelve of these patients had significantly higher local sIgE levels compared to controls, and also demonstrated positive NAPT results. The VAS scores, nasal airway resistance measured by active rhinomanometry, and the levels of local sIgE, ECP, histamine and leukotriene C4 were significantly increased from baseline values following NAPT. Sensitivity, specificity, and diagnostic accuracy of local sIgE for diagnosis of LAR were 91.7% respectively. CONCLUSIONS The measurement of local sIgE levels in nasal secretion is a reliable and effective diagnostic method for LAR.
