Abstract
OBJECTIVE The study aimed to explore whether microRNA-155 and FOXP3 could regulate invasive and migratory capacities of colorectal cancer (CRC) cells by mediating Zinc finger E-box binding homeobox 2 (ZEB2) expression. MATERIALS AND METHODS Dual-luciferase reporter gene assay was performed to detect the binding condition between microRNA-155, FOXP3, and ZEB2. Protein and mRNA levels of ZEB2 in CRC cells were detected after overexpression of microRNA-155 and FOXP3 by Western blot and quantitative Real Time-Polymerase Chain Reaction (qRT-PCR), respectively. In vitro experiments were conducted using HCT116 and SW620 cell lines. We first detected expression levels of microRNA-155, FOXP3, and ZEB2 in the normal colorectal epithelial cell line (NCM460) and CRC cell lines (HCT116 and SW620) by qRT-PCR. Protein expressions of ZEB2, E-cadherin, and vimentin in WT, LV-GFP, and LV-FOXP3 groups were detected. Wound healing assay and transwell assay were conducted to determine the regulatory effects of microRNA-155 and FOXP3 on invasive and migratory capacities of CRC cells, respectively. RESULTS Dual-luciferase reporter gene assay found that FOXP3 binds to the promoter and intron regions of ZEB2, and microRNA-155 binds to the 3'UTR region of wild-type ZEB2. Overexpression of FOXP3 downregulated mRNA and protein levels of ZEB2. ZEB2 was highly expressed, whereas microRNA-155 and FOXP3 were lowly expressed in HCT116 and SW620 cells than NCM460 cells. MicroRNA-155 overexpression upregulated E-cadherin and downregulated vimentin in CRC cells. Overexpression of FOXP3 and microRNA-155 inhibited invasive and migratory capacities of CRC cells. CONCLUSIONS MicroRNA-155 and FOXP3 can jointly regulate ZEB2 expression, thereby inhibiting the migration and invasion of colorectal cancer cells.

Abstract
BACKGROUND Up to 70% of patients with advanced ovarian cancer have a relapse after primary therapy. New agents and approaches are urgently needed to avoid or slow down this recurrence. OBJECTIVES To investigate the efficacy of PARP inhibitors (PARPis) as maintenance treatment in patients with newly diagnosed advanced ovarian cancer. SEARCH STRATEGY PubMed, MEDLINE, EMBASE, Cochrane Library and Web of Science databases. SELECTION CRITERIA All randomised clinical trials (RCTs) that compared PARPis with placebo as first-line maintenance therapy in ovarian cancer. DATA COLLECTION AND ANALYSIS Two reviewers extracted data. Pooled hazard ratio (HR) and risk ratio (RR) with 95% confidence interval (CI) were calculated. MAIN RESULTS PARPis were associated with significant improvement of progression-free survival (PFS) in advanced epithelial ovarian cancer (AeOC) (HR = 0.53, 95% CI 0.40-0.71; P < 0.0001). The benefit was not only in women with BRCA mutations (HR = 0.35, 95% CI 0.29-0.42; P < 0.00001) and homologous recombination deficiency (HRD) (HR = 0.43, 95% CI 0.32-0.60; P < 0.00001), but also in those with nonmutated BRCA (HR = 0.72, 95% CI 0.63-0.82; P < 0.00001) and even non-HRD (HR = 0.83, 95% CI 0.70-0.99; P = 0.04). CONCLUSIONS PARP inhibitors are effective as maintenance therapy among patients with newly diagnosed advanced ovarian cancer after platinum-based chemotherapy, regardless of BRCA mutation or HRD status. TWEETABLE ABSTRACT PARPis provide a significant PFS benefit as first-line maintenance therapy in patients with newly diagnosed advanced ovarian cancer.

Abstract
BACKGROUND In China, home-based healthcare/rehabilitation has always been advocated by the government and is the most prevalent healthcare pattern. However, there is currently no data on how many each product has been purchased, and it is not clear what factors are associated with their use. The research aims to clarify the current practices and attitudes of the elderly on such matters, and further analyze their influence factors. METHODS This pilot study consisted of two-round regional survey, conducted from July 25 to August 3, 2015 and July 20 to August 10, 2018 respectively. Both surveys released on-site paper questionnaires and collected after filling out in different communities. RESULTS Two hundred forty-four valid questionnaires from 52 communities were collected. Compared with 2015 (30.8%), the number of people who did not purchase home healthcare devices in the same area decreased in 2018 (28.2%). Hemopiezometer (44.3%), glucometer (18.4%), massager (21.3%) and walking devices (19.3%) are the four main types of products that urbanites are most willing to buy. In addition, users' age group, education level, and income level were significantly correlated with the purchase of certain products. CONCLUSIONS The types of home healthcare devices purchased by respondents are consistent with the distribution of chronic diseases of urban residents in China. The analysis of product brands also revealed the existing problems and huge growth space of the industry market, which also requires the government to introduce relevant policies and measures to regulate the market and accelerate the development of the industry.

Abstract
The rising prevalence of antibiotic resistance underscores the urgent need for novel antimicrobial agents. Antimicrobial peptides (AMPs) are potentially effective therapeutics that disrupt bacterial membranes regardless of resistance to traditional antibiotics. We have developed engineered cationic AMPs (eCAPs) with broad activity against multidrug-resistant (MDR) bacteria, but stability remains an important concern. Therefore, we sought to enhance the clinical utility of eCAP WLBU2 in biological matrices relevant to respiratory infection. A designed substitution of d-Val for l-Val resulted in increased resistance to protease enzymatic degradation. We observed multiple gains of functions such as higher activity against bacteria in biofilm mode of growth, significantly lower toxicity to erythrocytes and white blood cells compared to WLBU2, with increased safety in mice. Direct airway delivery revealed a therapeutic index of >140 for the selected enantiomer compared to that of <35 for WLBU2. The data warrant clinical exploration by aerosolized delivery to mitigate MDR-related respiratory infection.

Abstract
Objective: To investigate the risk factors associated with anastomotic leakage after robotic surgery in mid-low rectal cancer. Methods: A retrospective case-control study method was conducted. Inclusion criteria: (1) 18 to 80 years old; (2) pathologically confirmed rectal cancer; (3) distance <10 cm from tumor to anal margin; (4) robotic anterior rectal resection. Patients with previous history of colorectal cancer surgery, distant metastases or other malignant tumors, undergoing emergency surgery, with severe abdominal adhesions or those receiving combined organ resection were excluded. Based on the above criteria, 636 patients undergoing robotic radical sphincter-preserving surgery for mid-low rectal cancer in Zhongshan Hospital from January 2015 to December 2018 were included in this study, including 398 males (62.6%) and 238 females (37.4%) with a mean age of (61.9±11.3) years. Sixty-eight cases (10.7%) received neoadjuvant chemoradiotherapy. Amony the 636 included patients, 123(19.3%) underwent natural orifice specimen extraction surgery (NOSES) and 15 (2.3%) underwent preventive stoma. According to the cirteria developed by the International Rectal Cancer Research Group in 2010, the anastomotic leakage was classified as grade A (no requirement of intervention), B (requirement of intervention), and C (requirement of operation). Logistic regression was used to analyze the relationship between anastomotic leakage and clinicopathological factors. Factors in univariate analysis with P<0.05 were included in the multivariate analysis. Results: Anastomotic leakage occurred in 38 cases (6.0%). The grading of anastomotic leakage was grade A in 13 cases (2.0%), grade B in 19 cases (3.0%), and grade C in 6 cases (0.9%). The 3-year disease-free survival rate of patients with anastomotic leakage and without anastomotic leakage was 83.5% and 83.6% respectively (P=0.862); the 3-year overall survival rate of the two group was 85.1% and 87.5% respectively (P=0.296). The results of univariate logistic regression analysis showed that male (P=0.011), longer operation time (P=0.042), distance ≤5 cm from tumor to anal margin (P=0.012), more intraoperative blood loss (P=0.048) were associated with anastomotic leakage (all P<0.05). NOSES was not associated with anastomotic leakage (P=0.704). Multivariate analysis confirmed that male (OR=3.03, 95%CI: 1.37 to 7.14, P=0.010), operation time ≥180 minutes (OR=2.04, 95%CI: 1.03 to 3.99, P=0.040), distance ≤5 cm from tumor to anal margin (OR=2.56, 95%CI:1.28 to 5.26, P=0.008) were independent risk factors for anastomotic leakage. Conclusion: Male, short distance from tumor to anal margin, and long operation time are independent risk factors for anastomotic leakage in patients undergoing robotic mid-low rectal cancer radical surgeries. These patients need to be cautiously treated during surgery.

Abstract
Objectives Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Umifenovir (Arbidol®) is an antiviral drug being used to treat influenza in Russia and China. This study aimed to investigate the effectiveness and safety of umifenovir for COVID-19. Methods A retrospective study was performed in a non-intensive care unit (ICU) ward in Jinyintan Hospital from 2 February 2020 to 20 March 2020. COVID-19 was confirmed by real-time reverse-transcriptase polymerase chain reaction (RT-PCR) assay of pharyngeal swab specimens. The confirmed patients were divided into the umifenovir group and the control group according to the use of umifenovir. The main outcomes were the rate of negative pharyngeal swab tests for SARS-CoV-2 within 1 week after admission and the time for the virus to turn negative. The negativity time of SARS-CoV-2 was defined as the first day of a negative test if the nucleic acid of SARS-CoV-2 was negative for two consecutive tests. Results A total of 81 COVID-19 patients were included, with 45 in the umifenovir group and 36 in the control group. Baseline clinical and laboratory characteristics were comparable between the two groups. Thirty-three out of 45 (73%) patients in the umifenovir group tested negative for SARS-CoV-2 within 7 days after admission, the number was 28/36 (78%) in the control group (p 0.19). The median time from onset of symptoms to SARS-CoV-2 turning negative was 18 days (interquartile range (IQR) 12–21) in the umifenovir group and 16 days (IQR 11–21) in the control group (p 0.42). Patients in the umifenovir group had a longer hospital stay than patients in the control group (13 days (IQR 9–17) vs 11 days (IQR 9–14), p 0.04). No deaths or severe adverse reactions were found in both groups. Discussion Umifenovir might not improve the prognosis or accelerate SARS-CoV-2 clearance in non-ICU patients. A randomized control clinical trial is needed to assess the efficacy of umifenovir.

Macroinfauna responses and recovery trajectories after an oil spill differ from those following saltmarsh restoration. MARINE ENVIRONMENTAL RESEARCH 2020; 155:104881.

Abstract
Given the severity of injuries to biota in coastal wetlands from the Deepwater Horizon oil spill (DWH) and the resulting availability of funding for restoration, information on impacted salt marshes and biotic development of restored marshes may both help inform marsh restoration planning in the near term and for future spills. Accordingly, we performed a meta-analysis to model a restoration trajectory of total macroinfauna density in constructed marshes (studied for ~30 y), and with a previously published restoration trajectory for amphipods, we compared these to recovery curves for total macroinfauna and amphipods from DWH impacted marshes (over 8.5 y). Total macroinfauna and amphipod densities in constructed marshes did not consistently reach equivalency with reference sites before 20 y, yet in heavily oiled marshes recovery occurred by 4.5 y post spill (although it is unlikely that macroinfaunal community composition fully recovered). These differences were probably due to initial conditions (e.g., higher initial levels of belowground organic matter in oiled marshes) that were more conducive to recovery as compared to constructed marshes. Furthermore, we found that amphipod trajectories were distinctly different in constructed and oiled marshes as densities at oiled sites exceeded that of reference sites by as much as 20x during much of the recovery period. Amphipods may have responded to the rapid increase and high biomass of benthic microalgae following the spill. These results indicate that biotic responses after an oil spill may be quantitatively different than those following restoration, even for heavily oiled marshes that were initially denuded of vegetation. Our dual trajectories for oil spill recovery and restoration development for macroinfauna should help guide restoration planning and assessment following the DWH as well as for restoration scaling for future spills.

Abstract
We report constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment. We mitigate backgrounds with strong event selections, rather than requiring a scintillation signal, leaving an effective exposure of (22±3) tonne day. Above ∼0.4 keV_{ee}, we observe <1 event/(tonne day keV_{ee}), which is more than 1000 times lower than in similar searches with other detectors. Despite observing a higher rate at lower energies, no DM or CEvNS detection may be claimed because we cannot model all of our backgrounds. We thus exclude new regions in the parameter spaces for DM-nucleus scattering for DM masses m_{χ} within 3-6 GeV/c^{2}, DM-electron scattering for m_{χ}>30 MeV/c^{2}, and absorption of dark photons and axionlike particles for m_{χ} within 0.186-1 keV/c^{2}.

Abstract
Direct dark matter detection experiments based on a liquid xenon target are leading the search for dark matter particles with masses above ∼5 GeV/c^{2}, but have limited sensitivity to lighter masses because of the small momentum transfer in dark matter-nucleus elastic scattering. However, there is an irreducible contribution from inelastic processes accompanying the elastic scattering, which leads to the excitation and ionization of the recoiling atom (the Migdal effect) or the emission of a bremsstrahlung photon. In this Letter, we report on a probe of low-mass dark matter with masses down to about 85 MeV/c^{2} by looking for electronic recoils induced by the Migdal effect and bremsstrahlung using data from the XENON1T experiment. Besides the approach of detecting both scintillation and ionization signals, we exploit an approach that uses ionization signals only, which allows for a lower detection threshold. This analysis significantly enhances the sensitivity of XENON1T to light dark matter previously beyond its reach.

Methods: The mRNA expression level of GOLPH3 in PTC tissues and the matched adjacent noncancerous tissues from 30 cases of PTC undergoing surgical operation in Fujian Provincial Hospital between March 2017 and April 2018 was detected by reverse transcription-quantitative PCR (RT-qPCR). The protein expression of GOLPH3 in PTC tissues and the matched adjacent noncancerous tissues of 135 cases of PTC between January 2013 and April 2018 was measured by immunohistochemistry. The correlation between the expression of GOLPH3 in PTC and clinicopathologic characteristics and ATA risk of recurrence stratification was analyzed. Results: The mRNA level of GOLPH3 in PTC tissues was significantly higher than that in adjacent noncancerous tissues (7.53±1.32 vs 3.64±1.44, P<0.001). The protein expression level of GOLPH3 in PTC tissues was significantly higher than that in adjacent noncancerous tissues [66(30, 95) vs 34(20, 72), P<0.001]. The expression of GOLPH3 was significantly correlated to the tumor size (P=0.026), extrathyroid invasion (P=0.016), lymph node metastasis (P=0.001) and TNM stage (P=0.027) in PTC. Multivariate logistic regression analysis showed that GOLPH3 expression was independently correlated to tumor size (OR=3.58, 95%CI: 1.19-15.46, P=0.017) and lymph node metastasis (OR=7.28, 95%CI: 2.43-10.08, P=0.002). The expression of GOLPH3 was positively correlated to ATA risk of recurrence stratification (P=0.041). Conclusions: Overexpression of GOLPH3 is associated with the development of PTC and poor prognosis in patients with PTC. Detection of GOLPH3 expression can help evaluate proliferative and metastatic potential of PTC, as well as the risk of postoperative recurrence in patients with PTC.

Abstract
Candida albicans, a major opportunistic fungal pathogen, is frequently found together with Streptococcus mutans in dental biofilms associated with severe childhood caries (tooth decay), a prevalent pediatric oral disease. However, the impact of this cross-kingdom relationship on C. albicans remains largely uncharacterized. Here, we employed a novel quantitative proteomics approach in conjunction with transcriptomic profiling to unravel molecular pathways of C. albicans when cocultured with S. mutans in mixed biofilms. RNA sequencing and iTRAQ (isobaric tags for relative and absolute quantitation)-based quantitative proteomics revealed that C. albicans genes and proteins associated with carbohydrate metabolism were significantly enhanced, including sugar transport, aerobic respiration, pyruvate breakdown, and the glyoxylate cycle. Other C. albicans genes and proteins directly and indirectly related to cell morphogenesis and cell wall components such as mannan and glucan were also upregulated, indicating enhanced fungal activity in mixed-species biofilm. Further analyses revealed that S. mutans-derived exoenzyme glucosyltransferase B (GtfB), which binds to the fungal cell surface to promote coadhesion, can break down sucrose into glucose and fructose that can be readily metabolized by C. albicans, enhancing growth and acid production. Altogether, we identified key pathways used by C. albicans in the mixed biofilm, indicating an active fungal role in the sugar metabolism and environmental acidification (key virulence traits associated with caries onset) when interacting with S. mutans, and a new cross-feeding mechanism mediated by GtfB that enhances C. albicans carbohydrate utilization. In addition, we demonstrate that comprehensive transcriptomics and quantitative proteomics can be powerful tools to study microbial contributions which remain underexplored in cross-kingdom biofilms.

Abstract
Objective: To Effects of n-hexane on learning and memory and the expressions of nerve growth factor (NGF) mRNA and nerve growth factor receptor (NGFR) mRNA of brain tissue in mice exposed to N-hexane. Methods: 40 Kunming mice were randomly divided into low-dose group, meddle-dose group, high-dose dose group and control group, with 10 mice in each group. All the groups were orally exposed to n-hexane in different doses: low-dose group with 43.5 mg/kg, middle-dose group with 86.5 mg/kg and high-dose group with 173.0 mg/kg, 1 time per day for 20 d. After the poisoning, the Y-arm test and the expressions of NGF mRNA and NGFR mRNA and the concentrations of NGF and NGFR in the brain tissues of each group were measured. Results: In the first Y-arm test, there existed a significant difference in correct reaction rate generally in all groups (P<0.05), and correct reaction rate in the middle-dose group and the high-dose group were low significantly compared with that in the control group(P<0.05). In the second Y-arm test, there existed a significant differences in total electric shock time and correct reaction rate generally in all groups (P<0.01), and the total electric shock time prolonged significantly and the correct response rate decreased significantly in 3 dose groups compared with those of the control group(P<0.05). The expression levels of NGF mRNA in brain tissues of low, meddle and high dose-groups were 0.81±0.66, 0.67±0.37 and 0.69±0.26, and the expression levels of NGFR mRNA were 1.22±0.42, 1.98±0.84 and 2.01±2.01, respectively. Compared with the control group, the expressions of NGF mRNA in the 3 dose groups decreased significantly (P<0.05), and the expression of NGFR mRNA in middle-and high-dose groups increased significantly (P<0.05). The concentrations of NGF in brain tissues of low,meddle and high dose-groups were 39.97±7.24 ng/L, 39.26±7.88 ng/L,31.70±8.21 ng/L,and the concentrations of NGFR were 17.37±6.82 ng/L,21.37±7.16 ng/L, 22.46±7.70 ng/L, respectively. Compared with the control group, the concentrations of NGF in high-dose groups decreased significantly(P<0.05), and the concentrations of NGFR in middle-and high-dose groups increased significantly (P<0.05). Conclusion: N-hexane exposure can result in decrease of learning and memory in mice, which may be related to abnormal expression of NGF mRNA and NGFR mRNA in brain tissue.

Abstract
Giardia duodenalis is an important zoonotic intestinal protozoan of animals and humans. We collected 450 faecal specimens from four age groups (pre-weaned piglets, weaned piglets, juveniles, adults) of Zangxiang pigs from Shaanxi and Qinghai provinces, to investigate the prevalence and genetic diversity of G. duodenalis at the β-giardin (bg), triosephosphate isomerase (tpi) and glutamate dehydrogenase (gdh) loci using nested PCRs in the present study. A total of 28 faecal samples were positive for presence of G. duodenalis, with an overall prevalence of 6.2%. Giardia duodenalis was detected in pigs from all age groups and in both investigated provinces. Significant differences (P < 0.0001) in prevalence were observed among the four age groups with prevalence decreasing with age. Sequence analysis indicated existence of genetic diversity of G. duodenalis isolates from Zangxiang pigs, with 4, 2 and 4 haplotypes at the bg, tpi and gdh loci, respectively. Two assemblages were identified, including the zoonotic assemblage B and assemblage E, with the latter as the predominant assemblage found in both locations and all age groups except adults. The present study expanded the host range of G. duodenalis and provided fundamental data for controlling G. duodenalis infection in Zangxiang pigs.

Abstract
We report the first experimental results on spin-dependent elastic weakly interacting massive particle (WIMP) nucleon scattering from the XENON1T dark matter search experiment. The analysis uses the full ton year exposure of XENON1T to constrain the spin-dependent proton-only and neutron-only cases. No significant signal excess is observed, and a profile likelihood ratio analysis is used to set exclusion limits on the WIMP-nucleon interactions. This includes the most stringent constraint to date on the WIMP-neutron cross section, with a minimum of 6.3×10^{-42} cm^{2} at 30 GeV/c^{2} and 90% confidence level. The results are compared with those from collider searches and used to exclude new parameter space in an isoscalar theory with an axial-vector mediator.
