Abstract
Hereditary cancer syndromes result from the presence of inherited pathogenic variants within susceptibility genes. However, the susceptibility genes associated with hereditary cancer syndrome remain predominantly unidentified. Here, we reported a case of hereditary cancer syndrome observed in a Chinese family harboring a germline mutation in Tensin1 (TNS1). We described a 59-year-old female patient presented with Multiple myeloma and Thyroid carcinoma. The proband and her family members exhibited suspected tumor syndrome due to occurrences of other cancer cases. After oncogenetic counseling, whole-exome sequencing and Sanger sequencing were conducted and a primary driver mutation of TNS1 (NM_022648.7:c.2999-1G > C) was detected. Gene Expression Profiling Interactive Analysis revealed that TNS1 was expressed lower in different tumors when compared to normal, including Pancreatic adenocarcinoma, Breast invasive carcinoma, Thyroid carcinoma andColon adenocarcinoma cells. Despite the well-established role of TNS1 as a tumor suppressor in breast cancer and colorectal cancer, its potential utility as a marker gene for diagnosis and treatment of pancreatic cancer remains uncertain. Here, our data demonstrated that knockdown of TNS1 could promote cell proliferation and migration in Pancreatic adenocarcinoma (PDAC) cells. In addition, TNS1 regulated migration through EMT signaling pathway in PDAC cells. Our findings proposed that this variant was likely involved in cancer predisposition by disrupting the normal splicing process. In summary, we presented a genetic disease by linking an intronic mutation inTNS1. We aim to provide early detection of cancers by identifying germline variants in susceptibility genes.

Abstract
Liver cancer is the sixth most common cancer and the third leading cause of cancer-related death globally. Despite efforts being made in last two decades in cancer diagnosis and treatment, the 5-year survival rate of liver cancer remains extremely low. TRIM21 participates in cancer metabolism, glycolysis, immunity, chemosensitivity and metastasis by targeting various substrates for ubiquitination. TRIM21 serves as a prognosis marker for human hepatocellular carcinoma (HCC), but the mechanism by which TRIM21 regulates HCC tumorigenesis and progression remains elusive. In this study, we demonstrated that TRIM21 protein levels were elevated in human HCC. Elevated TRIM21 expression was associated with HCC progression and poor survival. Knockdown of TRIM21 in HCC cell lines significantly impaired cell growth and metastasis and enhanced sorafenib-induced toxicity. Mechanistically, we found that knockdown of TRIM21 resulted in cytosolic translocation and inactivation of YAP. At the molecular level, we further identified that TRIM21 interacted and induced ubiquitination of MST1, which resulted in MST1 degradation and YAP activation. Knockdown of MST1 or overexpression of YAP reversed TRIM21 knockdown-induced impairment of HCC growth and chemosensitivity. Taken together, the current study demonstrates a novel mechanism that regulates the Hippo pathway and reveals TRM21 as a critical factor that promotes growth and chemoresistance in human HCC.

Abstract
Background In 2019, the Louisiana Department of Health reported an early influenza B/Victoria (B/VIC) virus outbreak. Method As it was an atypically large outbreak, we deployed to Louisiana to investigate it using genomics and a triplex real-time RT-PCR assay to detect three antigenically distinct B/VIC lineage variant viruses. Results The investigation indicated that B/VIC V1A.3 subclade, containing a three amino acid deletion in the hemagglutinin and known to be antigenically distinct to the B/Colorado/06/2017 vaccine virus, was the most prevalent circulating virus within the specimens evaluated (86/88 in real-time RT-PCR). Conclusion This work underscores the value of portable platforms for rapid, onsite pathogen characterization.

Abstract
PURPOSE To investigate the effect of grape seed-derived proanthocyanidin B2 (GSPB2) pretreatment on acute renal ischemia-reperfusion injury model of mice. METHODS 50 mice were divided into 5 groups: Sham group: mice were treated with right nephrectomy. GSPB2 group: GSPB2 was injected intraperitoneally 45 min before right nephrectomy. IRI group: right kidney was resected and the left renal arteriovenous vessel was blocked for 45 min. GSPB2 + IRI group: GSPB2 was intraperitoneally injected 45 min before IRI established. GSPB2 + BRU + IRI group: GSPB2 and brusatol (BRU) were injected intraperitoneally 45 min before IRI established. Creatinine and urea nitrogen of mice were detected, and the kidney morphology and pathological changes of each group were detected by HE staining, PAS staining and transmission electron microscopy. Expressions of Nrf2, HO-1, GRP78, CHOP, and cleaved-caspase3 were detected by immunofluorescence staining and western blotting. RESULTS Morphology and mitochondrial damages of kidney in GSPB2 + IRI group were significantly alleviated than those in IRI group. Expression levels of Nrf2 and HO-1 were significantly higher in GSPB2 + IRI group than those in IRI group. Expression levels of GRP78, CHOP and cleaved-caspase3 were significantly lower in GSPB2 + IRI group than those in IRI group. However, compared to GSPB2 + IRI group, protective effects of GSPB2 pretreatment were weakened in GSPB2 + BRU + IRI group. CONCLUSIONS GSPB2 pretreatment could alleviate oxidative stress damage and reduce apoptosis of renal tubular epithelial cells, which might be related to activating the antioxidant system, up-regulating the expression of Nrf2 and HO-1, inhibiting the expressions of GRP78, CHOP and cleaved-caspase3. However, the protective effect could be reversed by brusatol.

Abstract
The production of waste printed circuit boards (WPCBs) is increasing, and its complex composition makes recycling difficult. In addition, the presence of heavy metals and brominated flame retardants makes it a hazardous waste. Therefore, its recycling is a necessary way for resource recycling and green sustainable development. The purpose of this study is to propose a green, efficient, and pollution-free recycling process as an alternative to recycle WPCBs. In this work, an alkaline metal oxide catalytic pyrolysis process was used to recover WPCBs. In the presence of alkali metal oxides (such as Ca(OH)2) and coexisting copper, Ca(OH)2 and coexisting copper are transformed into CaBr2 and Cu Br by reacting with organic bromine in WPCBs and remaining in the solid phase product. The bromine content and the proportion of inorganic bromine in the solid phase products were 87.68% and 87.56%, respectively. In addition, the content of organic bromine in the pyrolysis oil obtained by co-pyrolysis was significantly reduced. This study demonstrated the feasibility of Ca(OH)2 catalytic pyrolysis for WPCB recovery.

Abstract
OBJECTIVE To investigate the utility of fluorescence in situ hybridization (FISH) in secondary electroresection of bladder cancer. METHODS From January 2016 to April 2022, bladder cancer patients who had undergone secondary electroresection in Tongji Hospital and had preoperative urine FISH were recruited, and the positive rate, accuracy, sensitivity, specificity, genetic material changes and predictive power on malignancy degree of FISH in the secondary electroresection of bladder cancer were examined. RESULTS Twenty-six patients with bladder cancer were included in this study, and 8 were confirmed by secondary electroresection, including 6 cases positive for FISH positive and 2 negative for FISH. Besides, among the subjects, 18 were without tumor recurrence, including 1 case with positive FISH results and 17 with negative FISH results. Tumor recurrence was diagnosed in 85.71% (6/7) of FISH-positive patients in secondary electroresection while only 10.53% (2/19) of FISH-negative patients were found to develop tumor recurrence in the secondary electroresection. The sensitivity of FISH for the detection of bladder cancer before secondary electroresection was 75%, with a specificity of 94.44%, and an accuracy of 88.46%. A 6-month follow-up revealed that 2 of the 8 recurrent patients underwent radical resection of bladder cancer, and the remaining 6 patients had no recurrence, as confirmed by regular bladder perfusion and microscopy. In the 18 non-recurrent patients during secondary electroresection, no recurrence developed. CONCLUSIONS Urine FISH can achieve a high detection rate and specificity for secondary electroresection of bladder cancer. If a bladder cancer patient who are indicated for secondary electroresection is negative for urine FISH, the recurrence rate after secondary electroresection will be low, and the cystoscopy can be performed before deciding whether to perform secondary electroresection.

Abstract
In October 2020, an avian paramyxovirus serotype 14 (APMV-14)-designated chicken/Fujian/2160/2020 (FJ2160) was isolated from tracheal and cloacal swab sample of chicken collected from live bird market in Fujian province in China during the active surveillance program. The complete genome of FJ2160 comprised 15,444 nucleotides (nt) complying with the paramyxovirus "rule of six" and encoded six non-overlapping structural proteins in the order of 3'-NP-P-M-F-HN-L-'5. The complete genome sequence analysis showed that FJ2160 had the highest identity (90.0%) with the APMV-14 isolated from Japan, while the nucleotide sequence identities of FJ2160 and other APMVs ranged from 42.4 to 51.1%. The F protein cleavage site was TREGR↓L, which resembled a lentogenic strain of APMV-1. Phylogenetic analysis revealed that the FJ2160 closest relative was APMV-14. The intracerebral pathogenicity index (ICPI) tests indicated that the virus was lentogenic. This is the first report of APMV-14 in China. These results provide evidence that APMV-14 could infect chickens and reveal the genetic characteristics and biological properties of the virus, which can help to better understand this new emerging APMV-14.

Abstract
Ammonia (NH3) is a promising fuel, because it is carbon-free and easier to store and transport than hydrogen (H2). However, an ignition enhancer such as H2 might be needed for technical applications, because of the rather poor ignition properties of NH3. The combustion of pure NH3 and H2 has been explored widely. However, for mixtures of both gases, mostly only global parameters such as ignition delay times or flame speeds were reported. Studies with extensive experimental species profiles are scarce. Therefore, we experimentally investigated the interactions in the oxidation of different NH3/H2 mixtures in the temperature range of 750-1173 K at 0.97 bar in a plug-flow reactor (PFR), as well as in the temperature range of 1615-2358 K with an average pressure of 3.16 bar in a shock tube. In the PFR, temperature-dependent mole fraction profiles of the main species were obtained via electron ionization molecular-beam mass spectrometry (EI-MBMS). Additionally, for the first time, tunable diode laser absorption spectroscopy (TDLAS) with a scanned-wavelength method was adapted to the PFR for the quantification of nitric oxide (NO). In the shock tube, time-resolved NO profiles were also measured by TDLAS using a fixed-wavelength approach. The experimental results both in PFR and shock tube reveal the reactivity enhancement by H2 on ammonia oxidation. The extensive sets of results were compared with predictions by four NH3-related reaction mechanisms. None of the mechanisms can well predict all experimental results, but the Stagni et al. [React. Chem. Eng. 2020, 5, 696-711] and Zhu et al. [Combust. Flame 2022, 246, 115389] mechanisms perform best for the PFR and shock tube conditions, respectively. Exploratory kinetic analysis was conducted to identify the effect of H2 addition on ammonia oxidation and NO formation, as well as sensitive reactions in different temperature regimes. The results presented in this study can provide valuable information for further model development and highlight relevant properties of H2-assisted NH3 combustion.

Abstract
The low reactivity of ammonia (NH3) is the main barrier to applying neat NH3 as fuel in technical applications, such as internal combustion engines and gas turbines. Introducing combustion promoters as additives in NH3-based fuel can be a feasible solution. In this work, the oxidation of ammonia by adding different reactivity promoters, i.e., hydrogen (H2), methane (CH4), and methanol (CH3OH), was investigated in a jet-stirred reactor (JSR) at temperatures between 700 and 1200 K and at a pressure of 1 bar. The effect of ozone (O3) was also studied, starting from an extremely low temperature (450 K). Species mole fraction profiles as a function of the temperature were measured by molecular-beam mass spectrometry (MBMS). With the help of the promoters, NH3 consumption can be triggered at lower temperatures than in the neat NH3 case. CH3OH has the most prominent effect on enhancing the reactivity, followed by H2 and CH4. Furthermore, two-stage NH3 consumption was observed in NH3/CH3OH blends, whereas no such phenomenon was found by adding H2 or CH4. The mechanism constructed in this work can reasonably reproduce the promoting effect of the additives on NH3 oxidation. The cyanide chemistry is validated by the measurement of HCN and HNCO. The reaction CH2O + NH2 ⇄ HCO + NH3 is responsible for the underestimation of CH2O in NH3/CH4 fuel blends. The discrepancies observed in the modeling of NH3 fuel blends are mainly due to the deviations in the neat NH3 case. The total rate coefficient and the branching ratio of NH2 + HO2 are still controversial. The high branching fraction of the chain-propagating channel NH2 + HO2 ⇄ H2NO + OH improves the model performance under low-pressure JSR conditions for neat NH3 but overestimates the reactivity for NH3 fuel blends. Based on this mechanism, the reaction pathway and rate of production analyses were conducted. The HONO-related reaction routine was found to be activated uniquely by adding CH3OH, which enhances the reactivity most significantly. It was observed from the experiment that adding ozone to the oxidant can effectively initiate NH3 consumption at temperatures below 450 K but unexpectedly inhibit the NH3 consumption at temperatures higher than 900 K. The preliminary mechanism reveals that adding the elementary reactions between NH3-related species and O3 is effective for improving the model performance, but their rate coefficients have to be refined.

Abstract
BACKGROUND People living with HIV(PLWH) are deemed more vulnerable to the SARS-CoV-2 infection than the uninfected population. Vaccination is an effective measure for COVID-19 control, yet, little knowledge exists about the willingness of men who have sex with men (MSM) living with HIV in China to be vaccinated. METHODS This cross-sectional study evaluated the willingness of MSM living with HIV to receive COVID-19 vaccination in six cities of Guangdong, China, from July to September 2020. Factors associated with willingness to receive COVID-19 vaccination using multivariable logistic regression. RESULTS In total, we recruited 944 HIV-positive MSM with a mean age of 29.2 ± 7.7 years. Of all participants, 92.4% of them were willing to receive the COVID-19 vaccine. Participants who were separated, divorced, or widowed (adjusted OR: 5.29, 95%CI: 1.02-27.48), had an annual income higher than 9,000 USD (adjusted OR: 1.70, 95%CI: 1.01-2.86), had ever taken an HIV self-test (adjusted OR: 1.78, 95%CI: 1.07-2.95), had ever disclosed sexual orientation to a doctor/nurse (adjusted OR: 3.16, 95%CI: 1.33-7.50), had ever disclosed sexual orientation to others besides their male partners (adjusted OR: 2.18, 95%CI: 1.29-3.69) were more willing to receive the vaccine. Sex with a female partner in the past six months decreased the likelihood of willingness to receive the vaccine (adjusted OR: 0.40, 95%CI: 0.17-0.95). Economic burden, worry that my health condition could not bear the risk of receiving COVID-19 vaccines, and concern that the vaccination would affect the immune status and antiretroviral therapy were the main reasons for unwillingness to receive vaccination. CONCLUSION Our study showed that HIV-positive MSM had a high willingness to receive the COVID-19 vaccination. Targeted interventions such as health education should be conducted among MSM with HIV infection to enhance COVID-19 vaccine uptake.

Abstract
We currently have an incomplete understanding of why only a fraction of human antibodies that bind to flaviviruses block infection of cells. Here we define the footprint of a strongly neutralizing human monoclonal antibody (mAb G9E) with Zika virus (ZIKV) by both X-ray crystallography and cryo-electron microscopy. Flavivirus envelope (E) glycoproteins are present as homodimers on the virion surface, and G9E bound to a quaternary structure epitope spanning both E protomers forming a homodimer. As G9E mainly neutralized ZIKV by blocking a step after viral attachment to cells, we tested if the neutralization mechanism of G9E was dependent on the mAb cross-linking E molecules and blocking low-pH triggered conformational changes required for viral membrane fusion. We introduced targeted mutations to the G9E paratope to create recombinant antibodies that bound to the ZIKV envelope without cross-linking E protomers. The G9E paratope mutants that bound to a restricted epitope on one protomer poorly neutralized ZIKV compared to the wild-type mAb, demonstrating that the neutralization mechanism depended on the ability of G9E to cross-link E proteins. In cell-free low pH triggered viral fusion assay, both wild-type G9E, and epitope restricted paratope mutant G9E bound to ZIKV but only the wild-type G9E blocked fusion. We propose that, beyond antibody binding strength, the ability of human antibodies to cross-link E-proteins is a critical determinant of flavivirus neutralization potency.

Abstract
Dengue virus infection can cause dengue hemorrhagic fever (DHF). Dengue NS1 is multifunctional. The intracellular dimeric NS1 (iNS1) forms part of the viral replication complex. Previous studies suggest the extracellular secreted NS1 (sNS1), which is a major factor contributing to DHF, exists as hexamers. The structure of the iNS1 is well-characterised but not that of sNS1. Here we show by cryoEM that the recombinant sNS1 exists in multiple oligomeric states: the tetrameric (stable and loose conformation) and hexameric structures. Stability of the stable and loose tetramers is determined by the conformation of their N-terminal domain - elongated β-sheet or β-roll. Binding of an anti-NS1 Fab breaks the loose tetrameric and hexameric sNS1 into dimers, whereas the stable tetramer remains largely unbound. Our results show detailed quaternary organization of different oligomeric states of sNS1 and will contribute towards the design of dengue therapeutics.

Abstract
To expand our understanding of the epidemiology of pigeon paramyxovirus type 1 (PPMV-1) in China, risk-based active surveillance was undertaken with pigeon swabs collected from live bird markets in 2014-2021. Seventy-six PPMV-1 strains were isolated from 12 provinces (60%) of the 20 provinces surveyed, and the positive rates of PPMV-1 varied from 0.50% to 3.19% annually. The complete genomic sequences of 18 representative viruses were analyzed, revealing a genome of 15,192 nucleotides, with the gene order 3'-NP-P-M-F-HN-L-5'. All isolates contained the 112RRQKRF117 cleavage site in the fusion (F) protein, a characteristic generally associated with virulent Newcastle disease viruses (NDVs), and the intracerebral pathogenicity index values (1.05-1.41) of four isolates indicated their virulence. A challenge experiment also demonstrated that all four isolates are pathogenic to pigeons, with morbidity rates of 60-100% and mortality rates of 0-30%. A further analysis of the functional domains of the F and HN proteins revealed several mutations in the fusion peptide, signal peptide, neutralizing epitopes, heptad repeat region, and transmembrane domains, and the substitution of cysteine residue 25 (C25Y) and substitutions in the HRb region (V287I) of the F protein and the transmembrane domain (V45A) of the HN protein may play important roles in PPMV-1 virulence. In a phylogenetic analysis based on the complete sequences of the F gene, all eighteen isolates all clustered into sub-genotype VI.2.1.1.2.2 (VIb) in class II, and shared high nucleotide sequence identity, indicating that the PPMV-1 strains in sub-genotype VI.2.1.1.2.2 are the predominant PPMV-1 viruses in pigeons in China and that the variations in these viruses have been relatively stable over the past 8 years. This study identifies the genetic and pathogenicity characteristics of the PPMV-1 strains prevalent in China and extends our understanding of the prevalence of this virus in China.

Abstract
Hepatic fibrosis (HF) is caused by chronic hepatic injury and is characterized by hepatic stellate cells (HSCs) activation. Studies focusing on the function of exosomes derived from macrophages in HF progression are limited. This study aims to identify the roles of exosomal NEAT1 derived from macrophages on HF and the underlying mechanisms. Our studies showed that METTL3 targeted and enhanced NEAT1 expression in macrophages. Exosomal NEAT1 originating from LPS-treated macrophages promoted HSCs proliferation and migration, and induced the expression of fibrotic proteins including collagen I, α-SMA, and fibronectin. Macrophage exosomal NEAT1 contributed to HSCs activation by sponging miR-342. MiR-342 directly targeted Sp1 and suppressed its downstream TGF-β1/Smad signaling pathway, which eventually led to the inhibition of HSCs activation. Depletion of NEAT1 in the macrophage exosomes inhibited HF progression both in vitro and in vivo. Altogether, our study proved that silence of NEAT1 in the macrophage exosomes exerted protective roles against HF through the miR-342/Sp1/TGF-β1/Smad signaling pathway, suggesting a potential therapeutic target in HF treatment.

Abstract
The risk-based active surveillance for Newcastle disease virus (NDV) was carried out in China from 2011 to 2020. A total of 110,018 swabs were collected from 28 provinces. 2,389 class I NDVs were isolated and identified by RT-PCR and sequencing. The average annual positivity rate of class I NDVs from 2011 to 2020 was 2.17%. In the last 10 years, the positivity rate was highest in 2011 (4.76%), and has since decreased. Most viruses were isolated from chickens, while others were collected from ducks, geese and pigeons, as well as from the environment. The positivity rates for class I NDVs in poultry ranged from 0.55% to 2.40%. The viruses were isolated from 373 sampling sites in 24 provinces, mainly in East, Central, South and Southwest China. The positivity rates of NDVs in wholesale markets (51.58%) and retail markets (42.83%) were much higher than those in poultry farms (7.14%) and slaughterhouses (3.85%). Phylogenetic analyses showed that most isolates belonged to sub-genotype 1.1.2, while only 22 viruses belonged to sub-genotype 1.2, indicating the viruses in sub-genotype 1.1.2 were the predominant strains in China. The F and HN genes of six strains in the two sub-genotypes were sequenced and analyzed. The cleavage sites of F protein in the six viruses were 112ERQER/L117, 112ERQGR/L117 or 112GRQERL117, which were typical of low virulence NDV. Several mutations were identified in the functional domains of F and HN proteins, including fusion peptide, heptad repeat region, transmembrane domains and neutralizing epitopes. This study revealed the distribution, genetic and phylogenetic characteristics of class I NDVs in China, and could help us to better understand the epidemiological context of class I NDVs in China.

Abstract
The human monoclonal antibody (HmAb) C10 potently cross-neutralizes Zika virus (ZIKV) and dengue virus. Analysis of antibody fragment (Fab) C10 interactions with ZIKV and dengue virus serotype 2 (DENV2) particles by cryoelectron microscopy (cryo-EM) and amide hydrogen/deuterium exchange mass spectrometry (HDXMS) shows that Fab C10 binding decreases overall ZIKV particle dynamics, whereas with DENV2, the same Fab causes increased dynamics. Testing of different Fab C10:DENV2 E protein molar ratios revealed that, at higher Fab ratios, especially at saturated concentrations, the Fab enhanced viral dynamics (detected by HDXMS), and observation under cryo-EM showed increased numbers of distorted particles. Our results suggest that Fab C10 stabilizes ZIKV but that with DENV2 particles, high Fab C10 occupancy promotes E protein dimer conformational changes leading to overall increased particle dynamics and distortion of the viral surface. This is the first instance of a broadly neutralizing antibody eliciting virus-specific increases in whole virus particle dynamics.

Abstract
Pro-inflammatory M1 macrophages, via activating hepatic stellate cells, contribute to liver fibrosis. In this study, we examined the mechanism and the significance of a signaling axis, METTL3/MALAT1/PTBP1/USP8/TAK1, in regulating pyroptosis and M1 polarization of hepatic macrophages. Liver fibrosis model was established in vivo by CCl4 treatment; M1 polarization was induced in vitro by treating macrophages with lipopolysaccharide or interferon γ. Expressions of METTL3, MALAT1, PTBP1, USP8, and TAK1 were measured by RT-PCR and/or Western blot in Kupffer cells (KCs) isolated from in vivo model or in vitro activated macrophages. Macrophage phenotypes including inflammation (RT-qPCR analysis of a panel of proinflammatory cytokines and ELISA on productions of interleukin (IL)−1β and IL-18) and pyroptosis (Western blot of NLRP3, Caspase-1, and GSDMD) were investigated. The impact of METTL3 on m6A methylation of MALAT1 was examined by methylated RNA immunoprecipitation (RIP), the interaction between PTBP1 and MALAT1 or USP8 mRNA by combining RNA pull-down, RIP, and RNA stability assays, and the crosstalk between USP8 and TAK1 by co-immunoprecipitation and protein degradation assays. Functional significance of individual component of METTL3/MALAT1/PTBP1/USP8/TAK1 axis was assessed by combining gain-of-function and loss-of-function approaches. In KCs isolated from in vivo liver fibrosis model or in vitro M1-polarized macrophages, METTL3 was up-regulated, and sequentially, it increased MALAT1 level via m6A methylation, which promoted USP8 mRNA degradation through the interaction with PTBP1. Reduced USP8 expression regulated the ubiquitination and protein stability of TAK1, which promoted pyroptosis and inflammation of macrophages. The signaling cascade METTL3/MALAT1/PTBP1/USP8/TAK1, by essentially stimulating pyroptosis and inflammation of macrophages, aggravates liver fibrosis. Therefore, targeting individual components of this axis may benefit the treatment of liver fibrosis.

Abstract
Aiming at the problem of high cost in cold chain logistics of fresh products home-delivery in supermarket chain in the new retail era, the paper constructs the model of Location Inventory Routing Problem (LIRP) optimization in Satellite Warehouse mode in view of customer satisfaction with the broken line soft time windows. The model minimizes the total cost of the cold chain logistics system of supermarket chain through the location allocation, inventory optimization, the determination of distribution service relationship between Satellite Warehouse and customer, and the constraint of time penalty cost. Then, the paper designed an improved ant colony optimization to solve the LIRP model of supermarket chain. Finally, the simulation in MATLAB verifies and analyzes the validity of the model and algorithm. Therefore, LIRP optimization model in Satellite Warehouse mode can effectively improve the operational efficiency of fresh products home-delivery in the supermarket chain and thus reduce the logistics cost.

Abstract
PURPOSE Heat shock protein B8 (HSPB8) has been recently discovered to be participated in the regulation of tumor progression. However, the function of HSPB8 in intrahepatic cholangiocarcinoma (ICC) has not yet been elucidated. This study studied the function of HSPB8 in ICC progression. METHODS ICC patients (n = 150) were enrolled. The relationship between clinicopathological characteristics and HSPB8 expression was analyzed. RBE cells were transfected and treated by 3-MA. The RBE cells morphology was observed under a transmission electron microscope. Cell counting kit-8 assay, wound healing assay and Transwell experiment was conducted to detect RBE cells proliferation, migration and invasion. Quantitative reverse transcription-polymerase chain reaction, immunohistochemistry, Western blot and immunofluorescence were used for genes detection in clinical tissues and RBE cells. RESULTS HSPB8 was up-regulated in ICC tissues than that in adjacent normal tissues. High HSPB8 expression in ICC indicated poor prognosis of patients. HSPB8 expression was mainly expressed in cell cytoplasm and aberrantly increased in RBE cells (P < 0.01). HSPB8 up-regulation promoted RBE cells proliferation, migration and invasion (P < 0.05). HSPB8 down-regulation reduced RBE cells proliferation, migration and invasion (P < 0.01). HSPB8 overexpression facilitated Vimentin expression, LC3-II/LC3-I ratio and inhibited E-cadherin, p62 expression in RBE cells (P < 0.05). Treatment of 3-MA partially reversed HSPB8 promotion on RBE cells proliferation, migration, invasion and epithelial-mesenchymal transition (EMT) (P < 0.05 or P < 0.01). CONCLUSION HSPB8 promoted ICC progression by enhancing EMT and autophagy. HSPB8 might be an effective target for ICC treatment.

Abstract
Hepatic stellate cell activation, characterized by hyperproliferation and increased release of collagens, is a critical event during the initiation and development of hepatic fibrosis. The deregulated genes among different expression profiles based on online datasets were analyzed, attempting to identify novel potential biomarkers and treatment targets for hepatic fibrosis. The abnormal upregulation of mouse peptidylprolyl isomerase C (Ppic) within the CCl4-caused hepatic fibrosis model in mice was identified according to bioinformatics and experimental analyses. The knockdown of Ppic in the CCl4-caused liver fibrosis murine model significantly improved CCl4-caused liver damage, decreased the fibrotic area, reduced ECM deposition, and reduced the hydroxyproline levels. The knockdown of Ppic in TGF-β-stimulated mouse hepatic stellate cells inhibited cell proliferation and decreased ECM levels. Through direct targeting, miR-137-3p negatively regulated Ppic expression. Contrastingly to Ppic knockdown, miR-137-3p inhibition further promoted cell proliferation and boosted ECM levels; the effects of miR-137-3p inhibition could be partially reversed by Ppic knockdown. Altogether, mmu-miR-137-3p directly targets Ppic and forms a regulatory axis with Ppic, modulating CCl4-caused hepatic fibrosis in mice and TGF-β-caused mouse hepatic stellate cell activation.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019, and the outbreak rapidly evolved into the current coronavirus disease pandemic. SARS-CoV-2 is a respiratory virus that causes symptoms similar to those caused by influenza A and B viruses. On July 2, 2020, the US Food and Drug Administration granted emergency use authorization for in vitro diagnostic use of the Influenza SARS-CoV-2 Multiplex Assay. This assay detects influenza A virus at 102.0, influenza B virus at 102.2, and SARS-CoV-2 at 100.3 50% tissue culture or egg infectious dose, or as few as 5 RNA copies/reaction. The simultaneous detection and differentiation of these 3 major pathogens increases overall testing capacity, conserves resources, identifies co-infections, and enables efficient surveillance of influenza viruses and SARS-CoV-2.

Abstract
Peroxisome proliferator-activated receptor α (PPARα) play a key role in the regulation of metabolic homeostasis, inflammation, cellular growth, and differentiation. To further explore the potential role of PPARα in the energy homeostasis of fatty liver hemorrhagic syndrome (FLHS), we reported the prokaryotic expression and purification of chicken PPARα subunit protein, and successfully prepared a polyclonal antibody against PPARα recombinant protein. The 987 bp PPARα subunit genes were cloned into the pEASY-T3 clone vector. Then the plasmid PCR products encoding 329 amino acids were ligated to pEASY-Blunt E2 vector and transformed into BL21 to induce expression. The recombinant PPARα subunit protein, containing His-tag, was purified by affinity column chromatography using Ni-NTA affinity column. Rabbit antiserum was generated by using the concentration of recombinant PPARα subunit protein as the antigen. The results of western blotting showed that the antiserum can specifically recognize chicken endogenous PPARα protein. Immunohistochemistry and immunofluorescence showed that the PPARα mainly existed in the nucleus of hepatocytes, renal epithelial cells and hypothalamic endocrine nerve cells. More importantly, western blotting and real-time quantitative PCR indicated that FLHS significantly decreased the expression of PPARα.

Abstract
Hepatic stellate cells (HSCs) are the major source of extracellular matrix (ECM)-producing myofibroblasts. When activated by multiple injuries, HSCs become proliferative, contractile, inflammatory and chemotactic and are characterized by enhanced ECM production, which plays a central role in hepatic fibrosis initiation and progression. In the present study, through bioinformatics analysis, we identified the abnormal upregulation of Peripheral Myelin Protein 22 (PMP22) in fibrotic murine liver. In CCl4-induced hepatic fibrosis model in mice and TGF-β-activated hHSCs, PMP22 was observed remarkably upregulated. In TGF-β-stimulated hHSCs, PMP22 silencing hindered, whereas PMP22 overexpression aggravated TGF-β-induced hHSC activation. In CCl4-induced hepatic fibrosis model in mice, PMP22 silencing improved CCl4-caused liver damage and fibrotic changes. Through online tools prediction and experimental validation, miR-139-5p was found to bind to the 3'UTR of PMP22 and negatively regulate the expression of PMP22. In contrast to PMP22 silencing, miR-139-5p inhibition enhanced TGF-β-induced hHSC activation; the effects of miR-139-5p inhibition on TGF-β-induced hHSC activation were partially reversed by PMP22 silencing. In conclusion, we identify the abnormal upregulation of PMP22 in TGF-β-activated HSCs and CCl4-induced hepatic fibrosis model in mice, as well as the pro-fibrotic role of PMP22 through aggravating TGF-β-induced HSCs activation. miR-139-5p targets the 3'UTR of PMP22 and inhibits PMP22 expression; miR-139-5p hinders TGF-β-induced HSCs activation through targeting PMP22.

Abstract
BACKGROUND To evaluate the pattern and prevalence trends of liver cirrhosis caused by specific etiologies. RESULTS Globally, the number of prevalent cases increased 74.53% from 1990 to 2017. The ASR increased 0.75 per year. The most pronounced increases were found in middle-high and high socio-demographic index (SDI) regions, especially in the Caribbean and Latin America. Among the etiologies, non-alcoholic steatohepatitis (NASH) related liver cirrhosis accounted for 59.46% of the cases. The ASR increased 1.74 per year, and the increase was observed in all 5 SDI regions. In addition, the ASR of liver cirrhosis caused by alcohol also increased in both sexes and all SDI regions. In contrast, the ASR of liver cirrhosis caused by hepatitis B virus (HBV) and hepatitis C virus (HCV) decreased, especially in middle and low-middle SDI regions. CONCLUSIONS Though the number of people suffering from HBV and HCV decreases, liver cirrhosis is still a major threat to health. Additionally, the number of people with cirrhosis caused by alcohol and NASH continues to grow. Thus, more targeted and specific strategies should be established based on etiology and prevalence trends of liver cirrhosis. METHODS We collected data based on Global Burden of Disease (GBD) 2017 study. The age standardized prevalence rate (ASR) and estimated annual percentage changes (EAPC) were used to estimate the trends in prevalence by population, etiologies and regions.

Abstract
Background During the 2016/17 influenza season, influenza B/VIC lineage variant viruses emerged with two (K162N163) or three (K162N163D164) amino acid (aa) deletions in the haemagglutinin (HA) protein. There are currently five antigenically distinct HA proteins expressed by co-circulating influenza B viruses: B/YAM, B/VIC V1A (no deletion), B/VIC V1A-2DEL (2 aa deletion) and two antigenically distinguishable groups of B/VIC V1A-3DEL (3 aa deletion). The prevalence of these viruses differs across geographical regions, making it critical to have a sensitive, rapid diagnostic assay that detects and distinguishes these influenza B variant viruses during surveillance. Aim Our objective was to develop a real-time RT-PCR (rRT-PCR) assay for detection and discrimination of influenza B/VIC lineage variant viruses. Methods We designed a diagnostic assay with one pair of conserved primers and three probes specific to each genetic group. We used propagated influenza B/VIC variant viruses and clinical specimens to assess assay performance. Results This rRT-PCR assay detects and distinguishes the influenza B/VIC V1A, B/VIC V1A-2DEL, and B/VIC V1A-3DEL variant viruses, with no cross-reactivity. This assay can be run as a multiplex reaction, allowing for increased testing efficiency and reduced cost. Conclusion Coupling this assay with the Centers for Disease Control and Prevention’s Human Influenza Virus Real-Time RT-PCR Diagnostic Panel Influenza B Lineage Genotyping Kit results in rapid detection and characterisation of circulating influenza B viruses. Detailed surveillance information on these distinct influenza B variant viruses will provide insight into their prevalence and geographical distribution and could aid in vaccine recommendations.

Abstract
Background Influenza C virus (ICV) is associated with acute respiratory infection (ARI); however, the burden of ICV is not well-described. We sought to determine the burden and characteristics of ICV in a prospective, population-based cohort. Methods The study was conducted within the New Vaccine Surveillance Network (NVSN), a CDC-led, seven-site network that performs population-based surveillance for ARI in children < 5 years. Nasal/throat swabs were collected from emergency department (ED) or inpatient children with ARI, or healthy controls in clinic, between 12/05/2016-10/31/2019 and tested by real-time RT-PCR for ICV and other respiratory viruses. Preliminary data were extracted and demographic/clinical features of ICV+ cases analyzed. We sequenced the hemagglutinin-esterase (HE) gene from ICV+ Pittsburgh samples. Results Among 19,321 children with ARI or healthy controls enrolled and tested for ICV from 2016-2019, 115/17,668 (0.7%) ARI cases and 8/1653 (0.5%) healthy controls tested positive for ICV. The median age of ICV+ ARI subjects was 19 months (IQR 10,46) and 81(70%) were ≤36 months. 42.6% (49) were white, 33.9% (39) black, and 16.5% (19) Hispanic, with the remainder Asian or unknown; 56.5% (62) attended daycare. Among ICV+ ARI cases, 67.8% (78) had fever, 94.8% (109) cough, and 60.8% (70) wheezing. 45.2% (52) ICV+ cases occurred in 2016-17, 6.5% (8) in 2017-2018, and 47.8% (55) in 2018-19 (Table). 40% (46) of ICV+ cases were seen in the ED, while the remainder were inpatients. Median length of stay was 2d (IQR,1-3) with 15 admitted to ICU. 67.8% (78/115) ARI cases had 1 or 2 co-detected pathogens, with rhinovirus (26), respiratory syncytial virus (26), and adenovirus (14) most frequently co-detected. ARI symptoms including fever, myalgias, chills, and wheezing did not differ significantly between coinfected subjects and those who were only ICV+. HE sequences were in the two currently circulating Kanagawa and Sao Paulo lineages. ICV+ Cases by Site and Year ![]()
Conclusion ICV was an uncommon cause of ARI symptoms leading to healthcare encounters in young children. The prevalence varied year-to-year and between different geographic regions. Most children infected with ICV were ≤3 years old and had co-detected pathogens. ICV was similarly rarely detected in healthy controls. Disclosures Christopher J.

Abstract
Post-pancreaticoduodenectomy hemorrhage is a life-threatening complication that occurs in 2-10% of patients. The most common location for post-pancreaticoduodenectomy hemorrhage is the gastroduodenal artery stump. Nonetheless, unusual sources of hemorrhage, which are hard to locate, exist. Here, we report a rare postoperative hemorrhage after robotic-assisted pancreatoduodenectomy for pancreatic head cancer. A 67-year-old man presenting with appetite loss, general fatigue and painless jaundice was admitted to our ward. The patient had an elevated level of carbohydrate antigen 19-9 (50 U/mL). Computed tomography scan revealed a 17-mm wide low-density area in the uncinate process of the pancreas. Magnetic resonance cholangiopancreatography showed the dilation of bile and pancreatic ducts. Robotic-assisted pancreaticoduodenectomy was performed on the patient by using the da Vinci Model S Surgical System. On postoperative days 5 and 6, the patient vomited blood, and bloody fluid was observed in the drainage. Emergent gastroscopic examination was performed and revealed a large amount of hematocele in the stomach. On postoperative day 6, emergency operation was undertaken, and the output jejunal loop was found to have intussuscepted in the stomach. This is the first case report of output jejunal loop intussusception in the stomach that consequently caused hemorrhage after robotic-assisted pancreaticoduodenectomy for pancreatic head cancer.

Abstract
Objectives: Neuregulin 4 (NRG4) is a novel signaling protein involved in many physiological activities. This study aims to explore role of NRG4 in glioma. Study design: Serum samples were obtained from patients with glioma, RT-qPCR assay was performed to detect the levels
of NRG4 and ErbB4 in the patient's serum and glioma cell lines U251, SHG44, LN229 and T98G. The results suggested that the expression of NRG4 and ErbB4 were markedly higher in patients and glioma cell lines, especially in U251. Further, Small interfering RNAs (si-RNAs) that targeting NRG4
(si-NRG4) and the overexpressed plasmid of ErbB4 (pcDNA-ErbB4) were transfected into U251 cells. Cell proliferation was measured by CCK8 assay, migration and invasion was assessed by wound healing and transwell assays respectively. And the expression of PI3 K-p110 , PI3 K-p110 , pAKT-ser473,
pAKT-thr308 and AKT were measured by western blot assay. Results: We found that downregulation of NRG4 significantly inhibited proliferation, migration and invasion of U251 cells. Moreover, NRG4 inhibition markedly reduced the expression of PI3 K-p110 , pAKT-ser473 and pAKT-thr308.
And overexpression of ErbB4 alleviated the impact caused by NRG4 inhibition. Conclusion: NRG4 inhibition suppresses proliferation, migration and invasion of U251 via blocking the PI3 K/AKT pathway. NRG4 could serve as a potential target of glioma treatment.

Abstract
Background COVID-19 has spread globally. Epidemiological susceptibility to COVID-19 has been reported in patients with cancer. We aimed to systematically characterise clinical features and determine risk factors of COVID-19 disease severity for patients with cancer and COVID-19. Methods In this multicentre, retrospective, cohort study, we included all adult patients (aged ≥18 years) with any type of malignant solid tumours and haematological malignancy who were admitted to nine hospitals in Wuhan, China, with laboratory-confirmed COVID-19 between Jan 13 and March 18, 2020. Enrolled patients were statistically matched (2:1) with patients admitted with COVID-19 who did not have cancer with propensity score on the basis of age, sex, and comorbidities. Demographic characteristics, laboratory examinations, illness severity, and clinical interventions were compared between patients with COVID-19 with or without cancer as well as between patients with cancer with non-severe or severe COVID-19. COVID-19 disease severity was defined on admission on the basis of the WHO guidelines. Univariable and multivariable logistic regression, adjusted for age, sex, comorbidities, cancer type, tumour stage, and antitumour treatments, were used to explore risk factors associated with COVID-19 disease severity. This study was registered in the Chinese Clinical Trial Register, ChiCTR2000030807. Findings Between Jan 13 and March 18, 2020, 13 077 patients with COVID-19 were admitted to the nine hospitals in Wuhan and 232 patients with cancer and 519 statistically matched patients without cancer were enrolled. Median follow-up was 29 days (IQR 22–38) in patients with cancer and 27 days (20–35) in patients without cancer. Patients with cancer were more likely to have severe COVID-19 than patients without cancer (148 [64%] of 232 vs 166 [32%] of 519; odds ratio [OR] 3·61 [95% CI 2·59–5·04]; p<0·0001). Risk factors previously reported in patients without cancer, such as older age; elevated interleukin 6, procalcitonin, and D-dimer; and reduced lymphocytes were validated in patients with cancer. We also identified advanced tumour stage (OR 2·60, 95% CI 1·05–6·43; p=0·039), elevated tumour necrosis factor α (1·22, 1·01–1·47; p=0·037), elevated N-terminal pro-B-type natriuretic peptide (1·65, 1·03–2·78; p=0·032), reduced CD4+ T cells (0·84, 0·71–0·98; p=0·031), and reduced albumin–globulin ratio (0·12, 0·02–0·77; p=0·024) as risk factors of COVID-19 severity in patients with cancer. Interpretation Patients with cancer and COVID-19 were more likely to deteriorate into severe illness than those without cancer. The risk factors identified here could be helpful for early clinical surveillance of disease progression in patients with cancer who present with COVID-19.

Abstract
Objective: This study was to investigate whether there is impairment of auditory function in chronic rhinosinusitis (CRS).Study sample: A total of 85 patients were allocated into either the CRS group (n = 65) or a simple deviated nasal septum group (n = 20). Both groups without other risk factors for sensorineural hearing loss exhibited normal thresholds at standard audiometric frequencies. Another group (n = 30) of healthy subjects without CRS or a deviated nasal septum were gender and age matched.Design: Analyse the results of audiology test including pure tone audiometry, an acoustic impedance test, distortion product otoacoustic emissions (DPOAE) and the auditory brainstem response (ABR) for each subject analyse the test results of for each object.Results: The group differences were statistically significant for each high-frequency pure tone (p < 0.05). The ABR showed a difference between groups in amplitude. The DPOAE pass rate of the CRS group was lower than that of the control group.Conclusions: This study showed a significant correlation between CRS and auditory impairment. CRS might impair cochlear functions by damaging inner ear hair cells and/or, outer hair cells (OHCs), consequently altering the activity of the entire auditory pathway originating in the ventral cochlear nucleus (VCN) to the inferior colliculus.

Abstract
OBJECTIVE To discover the effect of cholesterol on dedifferentiation of VSMCs in vitro and the underlying mechanisms. METHODS Vascular smooth muscle cells (VSMC) were employed to evaluate the role of cholesterol in regulating the dedifferentiation of VSMCs in vitro. Immunofluorescent staining, western blot, and RT-PCR were applied to uncover the inducing effect of cholesterol at a molecular level. RESULTS We demonstrated that the cholesterol was capable of inducing the dedifferentiation of VSMCs. Mechanistic studies revealed that monocyte chemotactic protein-1-induced protein 1 (MCPIP1) composed the most influential factor in the regulation of VSMCs during the process of cholesterol induction. When MCPIP1 was overexpressed in VSMCs, the dedifferentiation, proliferation and migration of the cells was enhanced, and the expression of miR-145 was suppressed. In contrast, knocking down MCPIP1 by siRNA promoted the differentiation and prohibited the migration of VSMCs after cholesterol treatment. These results demonstrate that MCPIP1 plays an important role in regulating cholesterol-induced dedifferentiation of VSMCs in vitro.

Abstract
Raf kinase inhibitory protein (RKIP) is a well-established metastasis suppressor that is frequently down-regulated in aggressive cancers. However, the impact of RKIP on cancer cell invasion and metastasis in prostate cancer is still elusive. To this end, we overexpressed RKIP in two prostate cancer cell lines. We found that overexpression of RKIP inhibited prostate cancer cells proliferation, migration and invasion. Mechanistically, we found that RKIP overexpression led to down-regula- tion of the NF-kB signaling pathway and inhibition of the epithelial-to-mesenchymal transition, which is important step for cancer metastasis. In addition, overexpression of RKIP can promote drug effects of docetaxel on prostate cancer cell lines. In conclusion, overexpression of RKIP significantly inhibits prostate cancer cell migration and metastasis, and overexpression of RKIP could aid prostate cancer treatment and therapy.

Abstract
Objective To investigating the effect of bone marrow mesenchymal stem cells (BMSCs) pretreated with stromal cell-derived factor-1 (SDF-1) on carotid stenosis in rats. Methods The plasmid carrying enhanced green fluorescent protein (EGFP) was transfected into BMSCs and then intravenously injected into rats. The rats were divided into carotid artery injury model control group, BMSCs transplantation group, and BMSCs pretreated with SDF-1 group. Two weeks after the cell transplantation, the injured vascular tissues were collected and EGFP expression was detected by immunofluorescence histochemistry to determine the homing of BMSCs. Four weeks after cell transplantation, the endothelialization of injured intima was observed by Evans blue staining, and CD31 expression in injured vessels was detected by the immunofluorescence technique. The neointimal hyperplasia of injured carotid arteries was observed by HE staining. The expression of proliferating cell nuclear antigen (PCNA) in injured vessels was detected by immunohistochemical staining. The protein level of vascular endothelial growth factor (VEGF) was tested by Western blot analysis. Results The transplantation of BMSCs pretreated with SDF-1 could effectively promote the homing of BMSCs to injured blood vessels, and promote the re-endothelialization of injured vessels. The neointimal area and neointimal area/medial area in the two BMSC-transplantation groups were both lower than those in the model control group, which were more significantly different from the BMSCs pretreated with SDF-1 group. The transplantation of BMSCs pretreated with SDF-1 could significantly increase the expression of CD31 and VEGF in injured intima and inhibit the expression of PCNA. Conclusion The transplantation of BMSCs pretreated with SDF-1 can inhibit the proliferation of smooth muscle cells in the media and reduce arterial stenosis by promoting the migration of BMSCs to the injured site and inducing the differentiation of BMSCs.

Abstract
Background Longan (Dimocarpus longan Lour.) is an important fruit tree in the subtropical regions of Southeast Asia and Australia. Among the factors affecting D. longan fruit yield, the difficulty and instability of blossoming is one of the most challenging issues. Perpetual flowering (PF) is a crucial trait for fruit trees and is directly linked to production potential. Therefore, studying the molecular regulatory mechanism of longan PF traits is crucial for understanding and solving problems related to flowering. In this study, comparative transcriptome analysis was performed using two longan cultivars that display opposite flowering phenotypes during floral induction. Results We obtained 853.72 M clean reads comprising 125.08 Gb. After comparing these data with the longan genome, 27,266 known genes and 1913 new genes were detected. Significant differences in gene expression were observed between the two genotypes, with 6150 and 6202 differentially expressed genes (DEGs) for ‘SJ’ and ‘SX’, respectively. The transcriptional landscape of floral transition at the early stage was very different in these two longan genotypes with respect to key hormones, circadian rhythm, sugar metabolism, and transcription factors. Almost all flowering-related DEGs identified are involved in photoperiod and circadian clock pathways, such as CONSTANS-like (COL), two-component response regulator-like (APRRs), gigantea (GI), and early flowering (EFL). In addition, the leafy (LFY) gene, which is the central floral meristem identity gene, may inhibit PF formation in ‘SJ’. Conclusion This study provides a platform for understanding the molecular mechanisms responsible for changes between PF and seasonal flowering (SF) longan genotypes and may benefit studies on PF trait mechanisms of evergreen fruit trees.

Abstract
Background Sensorineural hearing loss is caused by defects in the inner ear. In the present study, associations between chronic rhinosinusitis, outer hair cell injury, and sensorineural hearing loss were investigated. Material/Methods A total of 103 patients who met the inclusion criteria were recruited and allocated into a chronic rhinosinusitis group (n=82) and a simple deviated nasal septum group (n=21). Degree and type of hearing loss, including distortion product otoacoustic emissions, were used to assess the status of cochlear outer hair cells. Results The rate of hearing loss in the simple deviated nasal septum group was significantly lower than in the chronic rhinosinusitis group (4.76%, 1/21 vs. 24.39%, 20/82, P<0.05), among which 15 chronic rhinosinusitis patients (75%, 15/20) had hearing loss in the high frequency range. Acoustic stapedial reflexes were elicited in all patients of the 2 groups, while positive Metz was found in 3 chronic rhinosinusitis patients (15%, 3/20). The pass rate of distortion product otoacoustic emissions (DPOAEs) for chronic rhinosinusitis patients was significantly lower than in simple deviated nasal septum patients (88.10% vs. 70.73%, P<0.05). Moreover, the signal-to-noise ratio of DPOAE test results at 704 Hz, 3991 Hz, and 5649 Hz in the chronic rhinosinusitis group were significantly lower than in the simple deviated nasal septum group (P<0.05). Logistic regression analysis revealed a correlation between severity of chronic rhinosinusitis and sensorineural hearing loss (OR=1.39, P<0.05). Conclusions Outer hair cell injury and sensorineural hearing loss may have a common cause in chronic rhinosinusitis patients.

Abstract
BACKGROUND AND AIM Serotonin and YAP exhibit a vital role in regulating cell proliferation and wound-healing response. The aim of the study was to investigate whether 5-HT could promote liver regeneration by activating YAP. METHODS PH models were established by WT and TPH1-/- mice. ELISA, RT-PCR, western blot, immunohistochemistry, flow cytometry and MTT assay were used to assess the level of 5-HT and YAP and proliferation after PH. RESULTS We found that 5-HT level was lower in the serum and liver of TPH1-/- mice. After PH, TPH1-/- mice, lacking in 5-HT, demonstrated worse regenerative ability and suffered more severe liver injury. Additionally, YAP expression was also lower in TPH1-/- mice. Moreover, we found that YAP expression was prominent within the first three days following PH. Similarly, 5-HT could promote cell proliferation by upregulating YAP expression in L-O2 cells. As predicted, using YAP-siRNA sharply reduced the proliferative capacity mediated by 5-HT. Further study also indicated that ERK participated in the regulation of YAP induced by 5-HT. By using an ERK inhibitor, the YAP expression and cell proliferation induced by 5-HT were both suppressed. Although YAP-siRNA was used to block YAP expression, pERK and ERK expression were not affected. Taken together, these data showed that 5-HT contributed to liver regeneration by regulating YAP expression, which at least in part, was by activation of pERK. CONCLUSION A role of the 5-HT-pERK-YAP axis in liver regeneration emerged from our study and might be a potential target to promote regeneration and injury repair.

Abstract
Fluid shear stress (FSS) may alter ciliary structures and ciliogenesis, and it has been reported that the Wnt signaling pathway may regulate cilia assembly and disas-sembly. The present study aimed to investigate the effects of FSS on primary cilia, the Wnt/β-catenin and Wnt/PCP signaling pathways, and the association among them. In the present study, human umbilical vein endothelial cells were subjected to FSS of differing velocities for various periods of time using a shear stress device. Subsequently, immunofluorescence and quantitative polymerase chain reaction were used to detect the expression and localization of the following core proteins: β-catenin in the Wnt/β-catenin signaling pathway; and dishevelled segment polarity protein 2 (Dvl2), fuzzy planar cell polarity protein (Fuz) and VANGL planar cell polarity protein 2 (Vangl2) in the Wnt/planar cell polarity (PCP) signaling pathway. Furthermore, the colocalization of Dvl2 with the basal body was analyzed under low FSS and laminar FSS. The results demonstrated that low FSS promoted the expression of Dvl2 and its colocalization with the basal body. Although Fuz expression was decreased with increasing duration of FSS, no visible alterations were detected in its localization, it was ubiquitously localized in the ciliated region. Conversely, the expression of Vangl2 was increased by laminar FSS, and β-catenin was translocated into the nucleus at the early stage of low FSS. These findings suggested that Dvl2 may participate in low FSS-induced ciliogenesis and β-catenin may participate at the early stage, whereas Vangl2 may be associated with laminar FSS-induced cilia disassembly.

Abstract
Urinary incontinence (UI) is a common complaint for adult female. Cross-sectional studies suggested parity may link with UI, but the association between them was not well-established. We conducted a meta-analysis to investigate the association between parity and UI.Medline and Embase were searched for eligible case-control and cohort studies about parity and UI. Two authors screened the literature and extracted the data independently. Odds ratio (OR) was used as the measure of the effect of parity on UI. We pooled the ORs of different number of parity by a random-effect model. Subgroup analysis was conducted by a subtype of UI. Sensitivity analysis was conducted to see whether the results were stable.Thirteen studies (8 cohorts and 5 case-controls) were included in our meta-analysis, with a total of 74,883 adult females. Our meta-analysis showed that compared with nulliparity, ORs of women with 1, 2, and ≥3 parity were 1.43 [95% confidence interval (95% CI): 0.90-2.28; I = 81.4%; n = 4], 1.50 (95% CI: 1.02-2.20; I = 82.5%; n = 4), and 1.58 (95% CI: 1.22-2.03; I = 70.1%; n = 7) compared with nulliparity. The OR for any multiparity to nulliparity was 1.68 (95% CI: 1.39-2.03; I = 0%; n = 4). Subgroup analysis showed that parity was associated with an increased risk of stress UI (OR = 2.32, 95% CI: 1.41-3.81; I = 0%; n = 2; 1 compared with null parity) but not urgent UI; However, the definition of parity varies across studies and studies defined parity as delivery times showed higher pooled OR than those not. Sensitivity analysis showed our results were stable.Current evidence suggested that parity was associated with an increased risk of overall and stress UI but not urgency UI, though the definition of parity may differ. Higher parity may have a more significant effect on overall UI. Standardized definition of parity is needed.

Abstract
An outbreak of influenza A(H7N2) virus in cats in a shelter in New York, NY, USA, resulted in zoonotic transmission. Virus isolated from the infected human was closely related to virus isolated from a cat; both were related to low pathogenicity avian influenza A(H7N2) viruses detected in the United States during the early 2000s.
