Abstract
Triple-positive breast cancer (TPBC) poorly responds to current standard neoadjuvant therapy (trastuzumab plus pertuzumab and chemotherapy). Our previous MUKDEN 01 study showed a promising total pathological complete response (tpCR) rate of 30.4% with neoadjuvant pyrotinib (pan-human epidermal growth factor receptor tyrosine kinase inhibitor) plus dalpiciclib (cyclin-dependent kinase 4/6 inhibitor) and letrozole, but the efficacy remains suboptimal. This pilot study (NCT05228951) explored adding trastuzumab to this triplet neoadjuvant regimen in patients with stage II-III TPBC. The primary endpoint was tpCR (ypT0/is, ypN0) rate. Between February 2022 and June 2022, 12 patients were enrolled, and seven (58%; 95% confidence interval [CI], 27.7%-84.8%) patients achieved tpCR. The rate of residual cancer burden (RCB) 0-I was 75% (95% CI, 46.8%-91.1%). The objective response rate (ORR) was 92% (95% CI, 64.6%-98.5%). Mean Ki-67 level was significantly reduced from 45.0% (95% CI, 19.5%-70.5%) at baseline to 17.2% (95% CI, 0.7%-33.7%) after neoadjuvant therapy (p = 0.03). The most common grade 3 adverse events were diarrhea (four [33%]) and decreased neutrophil count (three [25%]). No grade 4 adverse events or treatment-related deaths occurred. This four-drug neoadjuvant regimen shows promising pathological response with an acceptable safety profile in patients with TPBC. A randomized controlled trial (NCT05638594) of this regimen is being conducted.

Abstract
PURPOSE Diabetes and dyslipidemia are among the most common chronic diseases with increasing global disease burdens, and they frequently occur together. The study aimed to investigate differences in the heritability of glycemic traits and serum lipid indicators and differences in overlapping genetic and environmental influences between them across age groups. METHODS This study included 1189 twin pairs from the Chinese National Twin Registry and divided them into three groups: aged ≤ 40, 41-50, and > 50 years old. Univariate and bivariate structural equation models (SEMs) were conducted on glycemic indicators and serum lipid indicators, including blood glucose (GLU), glycated hemoglobin A1c (HbA1c), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), in the total sample and three age groups. RESULTS All phenotypes showed moderate to high heritability (0.37-0.64). The heritability of HbA1c demonstrated a downward trend with age (HbA1c: 0.50-0.79), while others remained relatively stable (GLU: 0.55-0.62, TC: 0.58-0.66, TG: 0.50-0.63, LDL-C: 0.24-0.58, HDL-C: 0.31-0.57). The bivariate SEMs demonstrated that GLU and HbA1c were correlated with each serum lipid indicator (0.10-0.17), except HDL-C. Except for HbA1c and LDL-C, as well as HbA1c and HDL-C, differences in genetic correlations underlying glycemic traits and serum lipids between age groups were observed, with the youngest group showing a significantly higher genetic correlation than the oldest group. CONCLUSION Across the whole adulthood, genetic influences were consistently important for GLU, TC, TG, LDL-C and HDL-C, and age may affect the shared genetic influences between glycemic traits and serum lipids. Further studies are needed to elucidate the role of age in the interactions of genes related to glycemic traits and serum lipids.

Abstract
Pseudomonas aeruginosa is an opportunistic pathogen that commonly causes infections in immunocompromised individuals with significant morbidity and mortality. Quercetin is a natural flavonoid abundantly present in fruits and vegetables, exerting potent anti-inflammatory effects in treatment of various diseases. However, the molecular mechanisms of quercetin in treatment of P. aeruginosa-induced acute lung inflammation are unclear. In this study, we exploited network pharmacology- and molecular docking-based approach to explore the potential mechanisms of quercetin against P. aeruginosa pneumonia, which was further validated via in vivo and in vitro experiments. The in vivo experiments demonstrated that quercetin alleviated the P. aeruginosa-induced lung injury by diminishing neutrophil infiltration and production of proinflammatory cytokines (IL-1β, IL-6, and TNF), which was associated with decreased mortality. Moreover, the quercetin-treated mice displayed decreased phosphorylation levels of PI3K, AKT, IκBα, and NF-κB p65 in lung tissues compared to non-drug-treated mice. Similarly, the in vitro study showed that the phosphorylation of these regulatory proteins and production of the proinflammatory cytokines were impaired in the quercetin-pretreated macrophages upon P. aeruginosa infection. Altogether, this study suggested that quercetin reduced the P. aeruginosa-induced acute lung inflammation by suppressing PI3K/AKT/NF-κB signaling pathway.

Abstract
The abuse of antibiotics has become a global public safety issue, leading to the development of antimicrobial resistance (AMR). The development of antimicrobial susceptibility testing (AST) is crucial in reducing the growth of AMR. However, traditional AST methods are time-consuming (e.g., 24-72 h), labor-intensive, and costly. Here, we propose a controlled-diffusion centrifugal microfluidic platform (CCM) for rapid AST to obtain highly precise minimum inhibitory concentration (MIC) values. Antibiotic concentration gradients are generated by controlled moving and diffusing of antibiotic and buffer solution along the main microchannel within 3 min. The solution and bacterial suspension are then injected into the outermost reaction chamber by simple centrifugation. The CCM successfully determined the MIC for three commonly used antibiotics in clinical settings within 4-9 h. To further enhance practicality, reduce costs, and meet point-of-care testing demands, we have developed an integrated mobile detection platform for automated MIC value acquisition. The proposed CCM is a simple, low-cost, and portable method for rapid AST with broad clinical and in vitro applications.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pseudomonas aeruginosa is an opportunistic bacterial pathogen which is the second leading cause of hospital-acquired pneumonia. Jingfang granule (JFG) is an herbal formula of Traditional Chinese medicine (TCM) widely used in treatment of acute respiratory tract infections in China. However, the molecular mechanisms of JFG in treatment of P. aeruginosa-induced acute pneumonia are not clear. AIM OF STUDY This study aimed to investigate the mechanisms underlying the effects of JFG on P. aeruginosa-induced acute inflammation using a mouse model of bacterial acute pneumonia. MATERIALS AND METHODS The chemical components and targets of JFG were retrieved from Traditional Chinese Medicine Systems Pharmacology (TCMSP) database, and the P. aeruginosa pneumonia-related targets were obtained from the disease databases, including Online Mendelian Inheritance in Man (OMIM), GeneCards and DisGeNet. The protein-protein interaction (PPI) network was constructed using STRING database. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed using the Database for Annotation, Visualization and Integrated Discovery (DAVID). Molecular docking was performed using AutoDockTools 1.5.6. Further in vivo experiments employed a mouse model of P. aeruginosa acute pneumonia to verify the target proteins and signaling pathways affected by JFG, which were predicted by the network pharmacology analysis. RESULTS A total of 218 active components and 257 targets of JFG were retrieved from TCMSP database. Moreover, 99 intersectant targets were obtained between the 257 JFG targets and 694 disease targets. Among the intersectant targets, STAT3, IL-6, AKT1, TNF, MAPK1, MAPK3 and EGFR were identified to be the key therapeutic targets through PPI network analysis, and STAT3 was in the center of the network, which is a key regulator of IL-17 expression. KEGG pathway enrichment analysis suggested that IL-17 signaling pathway was one of the crucial inflammatory pathways affected by JFG in treatment of P. aeruginosa pneumonia. Furthermore, the in vivo experiments demonstrated that the JFG-treated mice displayed reduced proinflammatory cytokine production (IL-17, IL-1β, IL-6 and TNF), diminished neutrophil infiltration and decreased mortality, compared with the non-drug-treated mice during P. aeruginosa lung infection. Moreover, the expression or phosphorylation levels of the key regulators in STAT3/IL-17/NF-κB axis including STAT3, ERK1/2 (MAPK3/1), AKT, NF-κB p65 and RORγt were significantly reduced in the lung tissues of the JFG-treated mice. CONCLUSION JFG was effective in treatment of P. aeruginosa acute lung infection, which reduced inflammatory responses through suppressing STAT3/IL-17/NF-κB pathway.

Abstract
Dabieshan tick virus (DBTV) is a newly identified arbovirus, first detected in Haemaphysalis longicornis collected from Hubei Province in 2015. It has been confirmed that DBTV is widely distributed in Shandong Province, China. However, its entomological and epidemiological features remain to be further explored, particularly the feasibility of transovarial transmission. Our research tries to explain the possibility of transovarial transmission of DBTV from engorged female ticks to their offspring. All engorged female adult ticks were sampled from domestic sheep and allowed to lay eggs and hatch in appropriate laboratory conditions. All engorged ticks, larvae and unhatched eggs were classified into pools for nucleic acid extraction and DBTV RNA detection. According to the results of qRT-PCR, the positive rate of DBTV was 6.25% (8/128) in engorged female ticks, 3.57% (1/28) in eggs and 5% (3/60) in larvae pools, respectively. Phylogenetic analysis indicated that DBTV isolates from larvae were similar to those from maternal ticks with more than 99.5% homology, and DBTV was relatively conservative in evolution. Our findings are the first to provide molecular evidence of potential transovarial transmission of DBTV among H. longicornis. Nonetheless, the transovarial transmission of DBTV in frequency and proportion occurring in nature deserves further investigation.

Abstract
Objective: To investigate the role and related mechanism of the highly expressed circular RNA molecule 103124 (hsa_circRNA_103124) in macrophage differentiation, pyroptosis and inflammation in peripheral blood mononuclear cells (PBMC) of patients with active Crohn's disease (CD). Methods: Patients with active CD (CD group) admitted to the Affiliated Suzhou Hospital of Nanjing Medical University from April to September 2018 and healthy people (control group) from the physical examination center of the hospital from July to October 2018 were retrospectively selected. The levels of hsa_circRNA_103124 and Toll-like receptor 4 (TLR4) in PBMC of the two groups were detected by real-time quantitative polymerase chain reaction (RT-qPCR). Tohoku hospital pediatrics-1 (THP1) cell line was used as a model for the study of hsa_circRNA_103124 regulating macrophage differentiation. Lentivirus infection was used to construct hsa_circRNA_103124 overexpressed or down-regulated THP1 cells to induce macrophage-like differentiation. According to the expression level of hsa_circRNA_103124, THP1 cell lines were divided into the following four groups: pLC5-ciR was overexpression control group; hsa_circRNA_103124 OE was the overexpression group; ShRNActrl was down-regulated expression control group; hsa_circRNA_103124 ShRNA was the down-regulated expression group. Flow cytometry was used to detect levels cluster of differentiation (CD) 68, CD80, interleukin (IL)-6, tumor necrosis factor α (TNF-α) and reactive oxygen species (ROS). The expression levels of IL-6, TNF-α, IL-1β, TLR4 and myeloid differentiation factor 88 (MyD88) were detected by RT-qPCR. The levels of gasdermin D (GSDMD), IL-18 and NOD-like receptor thermal protein domain associated protein 3 (NLRP3) were determined by immunofluorescence and RT-qPCR. Pearson correlation analysis was used to analyze the correlation between the abundance of hsa_circRNA_103124 and TLR4 expression level or Crohn's disease activity index (CDAI). Results: A total of 50 patients were included in the CD group, including 36 males and 14 females, aged (35±10) (19-64) years. A total of 30 subjects were included in the control group, including 22 males and 8 females, aged (38±9) (24-64) years. hsa_circRNA_103124 [(0.009±0.016) vs (0.003±0.002), P=0.042] and TLR4 [(0.005±0.003) vs (0.001±0.001), P<0.001] were all upregulated in the PBMC of patients in the CD group, compared with the control group. And hsa_circRNA_103124 was positively correlated with TLR4 (r=0.40, P=0.004). hsa_circRNA_103124 level was positively correlated with CDAI (r=0.32, P=0.024). The expression of CD68 (P=0.002) and CD80 (P<0.001) were enhanced. hsa_circRNA_103124 promoted production of ROS and the expression of IL-6, TNF-α, IL-1β, TLR4, MyD88, GSDMD, IL-18 and NLRP3 in macrophage-like M1 differentiated THP1 cells (all P<0.05). Conclusion: High expresion of hsa_circRNA_103124 in PBMC of patients with active CD may promote macrophage M1 differentiation, pyroptosis and inflammation through enhancing the expression of TLR4, MyD88, NLRP3 and GSDMD.

Abstract
Circular RNAs (circRNAs) have been accepted to play key roles in the development and progression of mutiple cancers including colorectal cancer (CRC). Here, we identified circ-METTL9, derived from 2 to 4 exons of METTL9 gene, may promote CRC progression by accelerating cell cycle progression. However, the role and mechanism of circ-METTL9 in CRC remains unclear. Based on our data, the expression of circ-METTL9 was significantly upregulated in CRC tissues and markedly increased in advanced tumors in CRC patients. Functional experiments demonstrated that circ-METTL9 overexpression promoted CRC cells proliferation and migration in vitro, and simultaneously enhanced CRC tumor growth and metastasis in vivo. Mechanistically, RNA immunoprecipitation (RIP) assays proved that circ-METTL9 might be a miRNA sponge, and RNA pulldown assays showed the interaction between circ-METTL9 and miR-551b-5p. Notably, cyclin-dependent kinase 6 (CDK6), a key regulator in cell cycle, is a conserved downstream target of miR-551b-5p. Taken together, our findings highlight a novel oncogenic function of circ-METTL9 in CRC progression via circ-METTL9/miR-551b-5p/CDK6 axis, which may serve as a prognostic biomarker and therapeutic target for CRC patients.

Abstract
Importance Acral melanoma, known for low tumor mutation burden, responds poorly to immunotherapy. A standard therapy is still lacking. Objective To investigate the activity and safety of camrelizumab (an anti-programmed cell death-1 antibody) plus apatinib (a vascular endothelial growth factor receptor 2 inhibitor) and temozolomide as first-line treatment in patients with advanced acral melanoma. Design, Setting, and Participants In this single-arm, single-center, phase 2 nonrandomized clinical trial, patients with treatment-naive unresectable stage III or IV acral melanoma were enrolled at Peking University Cancer Hospital and Institute between June 4, 2020, and August 24, 2021. The data cutoff date was April 10, 2022. Interventions Patients received 4-week cycles of intravenous camrelizumab, 200 mg, every 2 weeks; oral apatinib 250 mg, once daily; and intravenous temozolomide, 200 mg/m2, once daily on days 1 to 5 until disease progression or unacceptable toxic effects. Main Outcomes and Measures The primary end point was objective response rate as assessed by investigators according to the Response Evaluation Criteria In Solid Tumors (version 1.1). Secondary end points included progression-free survival, time to response, duration of response, disease control rate, overall survival, and safety. Results A total of 50 patients (32 men [64%]; median age, 57 years [IQR, 52-62 years]) were enrolled and received treatment. The median follow-up duration was 13.4 months (IQR, 9.6-16.2 months). The objective response rate was 64.0% (32 of 50; 95% CI, 49.2%-77.1%). The median time to response and duration of response were 2.7 months (IQR, 0.9-2.9 months) and 17.5 months (95% CI, 12.0 to not reached), respectively. The disease control rate was 88.0% (44 of 50; 95% CI, 75.7%-95.5%). The estimated median progression-free survival was 18.4 months (95% CI, 10.6 to not reached). The median overall survival was not reached. The most common grade 3 or 4 treatment-related adverse events were increased gamma-glutamyltransferase levels (15 [30%]), decreased neutrophil count (11 [22%]), increased conjugated bilirubin levels (10 [20%]), and increased aspartate aminotransferase levels (10 [20%]). No treatment-related deaths occurred. Conclusions and Relevance The findings of this nonrandomized clinical trial suggest that camrelizumab plus apatinib and temozolomide may be a potential first-line treatment option for patients with advanced acral melanoma, which warrants further validation in a randomized clinical trial. Trial Registration ClinicalTrials.gov Identifier: NCT04397770.

Abstract
Objective: To investigate the diagnostic and evaluation value of plasma interleukin 9 (IL9) in the mucosal healing (MH) in patients with inflammatory bowel disease (IBD) treated with biological agents. Methods: Cohort study. IBD patients (137 cases) treated in the Affiliated Suzhou Hospital to Nanjing Medical University (Suzhou Municipal Hospital) from September 2019 to January 2022 were prospective selected. Each patient was treated with biological agents [Infliximab (IFX, 56 cases), Adalimumab (ADA, 20 cases), Ustekinumab (UST, 18 cases), Vedolizumab (VDZ, 43 cases)]. According to different therapeutic drugs, the IFX, ADA, UST, and VDZ group were divided. Clinical symptoms, inflammatory indicators and imaging examinations etc. were evaluated every 8 weeks, and the degree of MH was evaluated by endoscopy at the 54th week. The expression of plasma IL9 was detected by ELISA after initial enrollment (W 0) and 8 weeks of biological treatment (W 8). Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficacy of IL9 for MH. Select the cut off value for the optimal ROC threshold based on the highest value of the Youden index. Spearman's rank correlation was used to analyze the correlation between IL9 and Simple Endoscopic Score for CD (SES-CD) and Mayo Endoscopic Score (MES), so as to evaluate the predictive value of IL9 for MH in IBD patients treated with biologic agents. Results: Among the 137 patients, there were 97 Crohn's disease (CD) patients, 53 males and 44 females, aged (31.6±10.3) years (18-60 years). There were 40 ulcerative colitis (UC) patients, 22 males and 18 females, aged (37.5±14.7) years (18-67 years). Among the CD patients, 42 cases (43.3%) achieved MH on endoscopy at the 54th week, and 60 patients (61.9%) achieved clinical remission. Among the UC patients, 22 cases (55.0%) achieved MH and 30 cases (75.0%) achieved clinical remission. At W 0, the relative expression of IL9 in patients in IBD patients who achieved MH after 54 weeks of biological treatment was lower than that in the non-MH patients [x¯±s, (127.42±34.43) vs (146.82±45.64) ng/L, (113.01±44.88) vs (146.12±48.66) ng/L, respectively, both P<0.05]. At W 8, the relative expression of IL9 in the MH group was lower than that in the non-MH patients (both P<0.05). The relative expression of IL9 in the MH patients after IFX treatment was lower than that in the non-MH group (P<0.05). There was no significant difference among the other groups between MH and non-MH patients (all P>0.05). IL9 at W 8 showed high value in predicting MH in IBD [CD patients: area under curve (AUC)=0.716(95%CI: 0.616-0.817, P<0.001), sensitivity and specificity were 80.77%(95%CI:67.64%-88.45%) and 48.89%(95%CI: 35.53%-64.47%), respectively; UC patients: AUC=0.821, sensitivity and specificity were 77.78% and 72.73%, respectively]. At W 8, the cut off values for CD and UC patients were IL9>80.77 ng/L and IL9>77.78 ng/L, respectively. IL9 was positively correlated with endoscopic MH score parameters [M(Q1,Q3),SES-CD: 3.0(8.5, 18.5); MES: 2.0(1.0, 3.0)] (r=0.55, 0.72, respectively, both P<0.001) at W8. Conclusion: The plasma IL-9 at the week 8 after biological agents treatment can be used to diagnose and evaluate the MH of patients with IBD.

Abstract
BACKGROUND Human epidermal growth factor receptor 2 (HER2) positive breast cancer is an aggressive subtype, accounting for around 20% of all breast cancers. The development of HER2-targeted therapy has substantially improved patient outcomes. Nevertheless, the increasing rate of side effects and resistance to targeted drugs limit their efficacy in clinical practice. In this study, we designed and synthesized a new immunotoxin, 4D5Fv-PE25, which targets HER2-positive breast cancer, and evaluated its effectiveness in vitro and in vivo. RESULTS The 4D5Fv-PE25 was expressed in high-density Escherichia coli (E. coli.) using the fermentor method and refined via hydrophobicity, ion exchange, and filtration chromatography, achieving a 56.06% recovery rate. Additionally, the semi-manufactured product with 96% purity was prepared into freeze-dried powder by the lyophilized process. Flow cytometry was used to detect the expression of HER2 in SK-BR-3, BT-474, MDA-MB-231, and MDA-MB-468 breast cancer cell lines. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) method was used for cytotoxicity assay, and the half-maximal inhibitory concentration (IC50) of 4D5Fv-PE25 lyophilized products to HER2-positive cell line SK-BR-3 was 12.53 ng/mL. The 4D5Fv-PE25 was injected into xenograft tumor mice via the tail vein on the 1st, 4th, and 8th day, it indicated that the growth of tumor volume was effectively inhibited for 24 days, although the 4D5Fv-PE25 was metabolized within 60 min by measuring the release of 3 H-Thymidine radiation. CONCLUSION we succeeded in producing the 4D5Fv-PE25 freeze-dried powder using the prokaryotic expression method, and it could be employed as a potential drug for treating HER2-positive breast cancer.

Abstract
Low-cost, rapid, and accurate acquisition of minimum inhibitory concentrations (MICs) is key to limiting the development of antimicrobial resistance (AMR). Until now, conventional antibiotic susceptibility testing (AST) methods are typically time-consuming, high-cost, and labor-intensive, making them difficult to accomplish this task. Herein, an electricity-free, portable, and robust handyfuge microfluidic chip was developed for on-site AST, termed handyfuge-AST. With simply handheld centrifugation, the bacterial-antibiotic mixtures with accurate antibiotic concentration gradients could be generated in less than 5 min. The accurate MIC values of single antibiotics (including ampicillin, kanamycin, and chloramphenicol) or their combinations against Escherichia coli could be obtained within 5 h. To further meet the growing demands of point-of-care testing, we upgraded our handyfuge-AST with a pH-based colorimetric strategy, enabling naked eye recognition or intelligent recognition with a homemade mobile app. Through a comparative study of 60 clinical data (10 clinical samples corresponding to six commonly used antibiotics), the accurate MICs by handyfuge-AST with 100% categorical agreements were achieved compared to clinical standard methods (area under curves, AUCs = 1.00). The handyfuge-AST could be used as a low-cost, portable, and robust point-of-care device to rapidly obtain accurate MIC values, which significantly limit the progress of AMR.

Abstract
This paper proposed a hand-powered centrifugal micropipette-tip strategy, termed HCM, for all-in-one immunoassay combined with a distance-based readout for portable quantitative detection of SARS-CoV-2. The target SARS-CoV-2 virus antigen triggers the binding of multiple monoclonal antibody-coated red latex nanobeads, forming larger complexes. Following incubation and centrifugation, the formed aggregated complexes settle at the bottom of the tip, while free red nanobeads remain suspended in the solution. The HCM enables sensitive (1 ng/mL) and reliable quantification of SARS-CoV-2 within 25 min. With the advantages of free washing, free fabrication, free instrument, and without the optical device, the proposed low-cost and easy-to-use HCM immunoassay shows great potential for quantitative POC diagnostics for SARS-CoV-2.

Abstract
BACKGROUND Chromosomal heterogeneity leads to the abnormal expression and mutation of tumor-specific genes. Drugs targeting oncogenes have been extensively developed. However, given the random mutation of tumor suppressor genes, the development of its targeted drugs is difficult. METHODS Our early research revealed that artificial circular single-stranded DNA (CSSD) can restore multiple tumor suppressor genes to inhibit tumor malignant progression by adsorbing miRNA. Here, we improved CSSD to a fully closed single-stranded DNA with G quadruplex DNA secondary structure (G4-CSSD), which made G4-CSSD with higher acquisition rate and decreased degradation. The Cancer Genome Atlas (TCGA) and Human Protein Atlas database were used to predict tumour suppressor genes in colon cancer. Cellular and animal experiments were performed to validate the role of G4-CSSD in cancer cell progression. RESULTS In colon cancer, we observed the simultaneous low expressions of chloride channel accessory 1 (CLCA1), UDP-GlcNAc:betaGal beta-1,3-N-acetylglucosaminyltransferase 6 (B3GNT6) and UDP glucuronosyltransferase family 2 member A3 (UGT2A3), which indicated an favourable prognosis. After repressing miR-590-3p with G4-CSSD590, the upregulation of CLCA1, B3GNT6 and UGT2A3 inhibited the proliferation and metastasis of colon cancer cells. CONCLUSIONS This study may provide basis for new treatment methods for colon cancer by restoration of tumor suppressor genes.

Abstract
The friction spot welding (FSpW) method was used to weld 2198-T8 Al-Li alloy at rotational speeds of 500 rpm, 1000 rpm, and 1800 rpm. It was shown that the grains in the FSpW joints were transformed from "pancake" grains to fine equiaxed grains by the heat input of welding, and the reinforcing phases of S' and θ were all redissolved into the Al matrix. This leads to a decrease in the tensile strength of the FsPW joint compared to the base material and a change in the fracture mechanism from mixed ductile-brittle fracture to ductile fracture. Finally, the tensile properties of the welded joint depend on the size and morphology of the grains and their dislocation density. At the rotational speed setting of 1000 rpm in this paper, the mechanical properties of welded joints consisting of fine and uniformly distributed equiaxed grains are best. Therefore, a reasonable set of the rotational speed of FSpW can improve the mechanical properties of the welded joints of 2198-T8 Al-Li alloy.

Abstract
Background Jingmen tick virus (JMTV) is a newly discovered tick-borne virus that can cause disease in humans. This virus has been authenticated as being extremely widespread worldwide and as posing a significant threat to public health and safety. Methods We collected 35 ticks belonging to two tick species from wild boars in Nanping, Fujian Province, China. JMTV-specific genes were amplified by qRT-PCR and nested PCR to confirm the presence of this pathogen. Results More than one third of of all ticks collected (11/35) were positive for JMTV. Viral sequences were obtained from three of the JMTV-positive ticks, including the complete genomic sequence from one tick. This was the first time that JMTV was identified in the hard-bodied tick Amblyomma testudinarium. Phylogenetic analysis revealed that JMTV from Fujian Province shared > 90% identity with other isolates derived from China, but was distinct from those reported in France and Cambodia. Conclusions JMTV is characterized by relatively low mutations and has its own local adaptive characteristics in different regions. Our findings provide molecular evidence of the presence of JMTV in an overlooked tick species from an area not unrecognized as being endemic. They also suggest that JMTV occupies a wider geographical distribution than currently believed and is a potential disease vector. Graphical abstract ![]()

Abstract
Aldosterone is the most important mineralocorticoid hormone regulating water and electrolyte absorption in the distal convoluted tubule of the kidney. Recently, we detected the presence of the whole chain of aldosterone production from the precursor corticosterone, transcription factor liver receptor homologue-1 (LRH-1), the aldosterone synthase enzyme protein (CYP11B2) as well as the gene to the final product aldosterone in murine large intestine. Here, we decided to correlate the amount of this synthase protein with its enzymatic activity in different parts of gastrointestinal tract and also with the aldosterone concentration in the respective tissue. Considering the physiological behavior of the animals in light and dark environment, we measured these variables at four time points - two in the light, the others during darkness. In vitro activity of CYP11B2 was measured as the amount of aldosterone formed from the precursor deoxycorticosterone using enzyme preparations from homogenized intestinal sections. CYP11B2 enzyme activity was higher in the large than in the small intestine. In ileum and colon, the CYP11B2 activity increased in the dark time. The highest aldosterone concentration was detected in the dark in the large intestine. In summary, enzyme activity of CYP11B2 was present in all parts of intestine; the large intestine formed more aldosterone during the darkness. No difference was seen in any of the variables between the early and late light hours.

Abstract
Jingmen tick virus (JMTV) is a novel tick-borne segmented RNA virus that is closely related to un-segmental RNA virus in evolution. It has been confirmed that JMTV could be a causative agent of human disease. In this study, a total of 3658 ticks were sampled from 7 provinces of China and then divided into 545 pools according to the location and species. QRT-PCR and nested PCR were performed to confirm the presence of JMTV. The results showed JMTV was identified in 5 out of 7 provinces with an average infection rate of 1.4% (51/3658). Phylogenetic analysis indicated that all JMTV strains identified in this study were closely related to each other and formed a well-supported sub-lineage. Our results provide molecular evidence of JMTV in different species of ticks from endemic and non-endemic regions and demonstrate that JMTV, as a natural foci pathogen, may be widely distributed all over China. JMTV was first identified in unrecognized endemic regions of China Two complete genomes and 13 partial S1 segments of JMTV were sequenced and analyzed JMTV was relatively conservative in evolution JMTV was widely distributed in China as a potential health threat to humans and animals

Abstract
The epithelial mesenchymal transition (EMT) has roles in metastasis and invasion during fibrotic diseases and cancer progression. Some Traditional Chinese Medicines (TCMs) have shown inhibitory effects with respect to the EMT. The current study attempted to establish a multiparametric high-content method to screen for active monomeric compounds in TCM with the ability to target cellular EMT by assessing phenotypic changes. A total of 306 monomeric compounds from the MedChemExpress (MCE) compound library were screened by the high-content screening (HCS) system and 5 compounds with anti-EMT activity, including camptothecin (CPT), dimethyl curcumin (DMC), artesunate (ART), sinapine (SNP) and berberine (BER) were identified. To confirm anti-EMT activity, expression of EMT markers was assessed by qRT-PCR and Western blotting, and cell adhesion and migration measured by cell function assays. The results revealed that CPT, DMC, ART, SNP and BER inhibited transforming growth factor-β1 (TGF-β1)-induced expression of vimentin and α-SMA, upregulated expression of E-cadherin, increased cell adhesion and reduced cell migration. In summary, by quantifying the cell morphological changes during TGF-β1-induced EMT through multi-parametric analysis, TCM compounds with anti-EMT activity were successfully screened using the HCS system, a faster and more economical approach than conventional methods.

Abstract
9508 Background: PD-1 monotherapy as the first line stand treatment for advanced melanoma yields an objective response rate (ORR) of < 20% in AM. Although multiple clinical trials are ongoing testing TMZ/APA, TMZ/PD-1 and APA/PD-1 combo therapies in AM, the reported ORR (range 17-23.8%) are far from satisfactory. We therefore conducted a phase II study of CAM/APA/TMZ combo in this subtype aiming for improved efficacy. Methods: We performed a single center, single arm phase II study (NCT04397770) testing the efficacy and safety of CAM/APA/TMZ combo as first-line therapy in pts with advanced AM. The primary endpoint was ORR per RECIST1.1, secondary endpoints included progression free survival (PFS), disease control rate (DCR), overall survival (OS), and safety. All pts received iv CAM (200mg q2w), iv TMZ (200mg/m2 d1-5, q4w) and po APA (250mg qd) until disease progression or intolerable toxicity. Results: By Jan 2022, fifty pts were enrolled (48 evaluable), the median follow-up was 12.1 mo (IQR 8.4-14.5). Thirty-one pts achieved CR/PR as the best response (including 1 CR and 30 PR), the ORR was 64.6% (95% CI 49.4-77.4%). The DCR was 95.8% (95%CI, 84.6-99.3%). Both the median PFS and OS was not reached (NR); 6-mo and 12-mo PFS rate was 81.7% (95%CI 71.6-93.3%) and 62.9% (95%CI 48.4-81.7%), respectively; 12-mo OS rate was 82.3% (95%CI 68.2-99.2%). The incidence of treatment-related adverse events (TRAEs) was 94% (47/50). Of 50 patients, the most common grade ≥3 TRAEs included γ-glutamyl transferase elevation (24.0%), direct bilirubin elevation (22.0%), aspartase transaminase elevation (20.0%), alanine transaminase elevation (16.0%), and hypertriglyceridemia (14.0%). No treatment-related deaths occurred. Conclusions: The CAM/APA/TMZ combination demonstrated promising efficacy as the first-line treatment for pts with advanced AM, and was generally well tolerated. Phase III randomized control trial is warranted. Clinical trial information: NCT04397770.

Abstract
Drug resistance, undesirable toxicity and lack of selectivity are the major challenges of conventional cancer therapies, which cause poor clinical outcomes and high mortality in many cancer patients. Development of alternative cancer therapeutics are highly required for the patients who are resistant to the conventional cancer therapies, including radiotherapy and chemotherapy. The success of a new cancer therapy depends on its high specificity to cancer cells and low toxicity to normal cells. Utilization of bacteria has emerged as a promising strategy for cancer treatment. Attenuated or genetically modified bacteria were used to inhibit tumor growth, modulate host immunity, or deliver anti-tumor agents. The bacteria-derived immunotoxins were capable of destructing tumors with high specificity. These bacteria-based strategies for cancer treatment have shown potent anti-tumor effects both in vivo and in vitro, and some of them have proceeded to clinical trials. Pseudomonas aeruginosa, a Gram-negative bacterial pathogen, is one of the common bacteria used in development of bacteria-based cancer therapy, particularly known for the Pseudomonas exotoxin A-based immunotoxins, which have shown remarkable anti-tumor efficacy and specificity. This review concisely summarizes the current knowledge regarding the utilization of P. aeruginosa in cancer treatment, and discusses the challenges and future perspectives of the P. aeruginosa-based therapeutic strategies.

Abstract
Point-of-care testing (POCT) has shown great advantages for public health monitoring in resource-limited settings. However, developing of POCT tools with automated and accurate quantitative dispensing of multiple reagents and samples is challenging. Here, we demonstrate a novel multi-reagents dispensing centrifugal microfluidics (MDCM) that allows rapid and automated dispensing of multiple reagents and samples with high throughput and accuracy. The MDCM was designed with multiple aliquoting units with the hydrophobic valve at different radial positions. All reagents and samples were loaded simultaneously, dispensed in parallel by centrifugation at low speed, and then introduced into the reaction chamber sequentially by centrifugation at high speed. Two MDCM chips are demonstrated, including a uniform concentration generator and a gradient concentration generator. The concentration coefficient of variation (CV) among the independent reaction chambers was lower than 0.56%, and the theoretical quantitative concentration gradient was strongly correlated with the actual concentration gradient (R2 = 0.9938). We have successfully applied the MDCM to loop-mediated isothermal amplification (LAMP)-based nucleic acid detection for multiple infectious pathogens and antimicrobial susceptibility testing (AST) for kanamycin sulfate against E. coli. To further extend the applications, the MDCM has also been applied to bicinchoninic acid (BCA) protein assays with online calibration, reducing the detection time from 2 h to 10 min with a twenty-fold reduction in reagent consumption. These results indicated that the MDCM is a high potential platform for POCT.

Abstract
Pseudomonas aeruginosa is an opportunistic pathogen that causes life-threatening infections in cystic fibrosis patients and immunocompromised individuals. A tightly regulated immune response possessed by healthy individuals can effectively control P. aeruginosa infections, whereas the patients with dysregulated immune response are susceptible to this bacterial pathogen. Early growth response 1 (Egr-1) is a zinc-finger transcription factor involved in regulation of various cellular functions, including immune responses. We previously identified that Egr-1 was deleterious to host in a mouse model of acute P. aeruginosa pneumonia by promoting systemic inflammation and impairing bacterial clearance in lung, which associated with reduced phagocytosis and bactericidal ability of leucocytes, including macrophages and neutrophils. However, the molecular mechanisms underlying the Egr-1-suppressed phagocytosis of P. aeruginosa are incompletely understood. Herein, we investigated whether the Egr-1-regulated autophagy play a role in macrophage phagocytosis during P. aeruginosa infection by overexpression or knockdown of Egr-1. We found that overexpression of Egr-1 inhibited the phagocytic activity of macrophages, and the autophagy activator rapamycin and inhibitor chloroquine could reverse the effects of Egr-1 knockdown and Egr-1 overexpression on phagocytosis of P. aeruginosa, respectively. Furthermore, the Egr-1-overexpressing macrophages displayed upregulated expression of autophagy-related proteins LC3A, LC3B and Atg5, and decreased levels of p62 in macrophages. Further studies revealed that the macrophages with Egr-1 knockdown displayed enhanced activation of transcription factor NRF2 and expression of scavenger receptors MACRO and MSR1. Altogether, these findings suggest that Egr-1 suppresses the phagocytosis of P. aeruginosa by macrophages through upregulation of autophagy and inhibition of NRF2 signaling.

Abstract
Mast cells (MCs) are key mediators of allergic inflammation through the activation of cross-linked immunoglobulin E (IgE) bound to the high-affinity IgE receptor (FcϵRI) on the cell surface, leading to the release of biologically potent mediators, either from preformed granules or newly synthesized. Pharmacological inhibitors have been developed to target a key signaling protein phosphatase in this pathway, calcineurin, yet there is a lack of genetic and definitive evidence for the various isoforms of calcineurin subunits in FcϵRI-mediated responses. In this study, we hypothesized that deficiency in the calcineurin Aα isoform will result in a decreased allergic immune response by the MCs. In a model of passive cutaneous anaphylaxis, there was a reduction in vascular permeability in MC-deficient mouse tissues reconstituted with calcineurin subunit A (CnAα) gene-knockout (CnAα<sup>−/−</sup>) MCs, and in vitro experiments identified a significant reduction in release of preformed mediators from granules. Furthermore, released levels of de novo synthesized cytokines were reduced upon FcϵRI activation of CnAα<sup>−/−</sup> MCs in vitro. Characterizing the mechanisms associated with this deficit response, we found a significant impairment of nuclear factor of kappa light polypeptide gene enhancer in B cell phosphorylation and impaired nuclear factor kappa-light-chain-enhancer of activated B-cell inhibitor alpha (NF-κB) activation. Thus, we concluded that CnAα contributes to the release of preformed mediators and newly synthesized mediators from FcϵRI-mediated activation of MCs, and this regulation includes NF-κB signaling.

Abstract
Aldosterone, the main physiological mineralocorticoid, regulates sodium and potassium balance in the distal convoluted tubule of the kidney. Aldosterone is synthesized from cholesterol in the adrenal cortex in a sequence of enzymatic steps. Recently however, several tissues or cells e.g. brain, heart, blood vessels, kidneys and adipocytes have been shown to possess capability to produce aldosterone locally, and there is some evidence that this occurs also in the intestine. Colon expresses mineralocorticoid receptors and is capable of synthesizing corticosterone, the second last intermediate on the route to aldosterone from cholesterol. Based on such reports and on our preliminary finding, we hypothesized that aldosterone could be synthesized locally in the intestine and therefore we measured the concentration of aldosterone as well as the protein and gene expression of aldosterone synthase (CYP11B2), an enzyme responsible on aldosterone synthesis, from the distal section of the gastrointestinal tract of 10-week-old Balb/c male mice. It is known that sodium deficiency regulates aldosterone synthesis in adrenal glands, therefore we fed the mice with low (0.01%), normal (0.2%) and high-sodium (1.6%) diets for 14 days. Here we report that, aldosterone was detected in colon and cecum samples. Measurable amounts of CYP11B2 protein were detected by Western blot and Elisa analysis from both intestinal tissues. We detected CYP11B2 gene expression from the large intestine along with immunohistochemical findings of CYP11B2 in colonic wall. Sodium depletion increased the aldosterone concentration in plasma compared to control and high-sodium groups as well as in the intestine compared to mice fed with the high-sodium diet. To summarize, this study further supports the presence of aldosterone and the enzyme needed to produce this mineralocorticoid in the murine large intestine.

Abstract
Pseudomonas aeruginosa is an opportunistic pathogen causing life-threatening infections in cystic fibrosis patients and immunocompromised individuals, and it is a leading cause of nosocomial infections associated with significant morbidity and mortality. Treatment of P. aeruginosa infections is challenging due to the antibiotic resistance to most of the conventional antibiotics. Development of alternative therapeutic options is urgently demanded for the patients who have antibiotic-resistant infections. Traditional Chinese medicine (TCM) has a clinical history of thousands of years for prevention and treatment of infectious diseases in China, taking advantages of improving clinical outcomes, producing less side effects, inhibiting pathogen, and modulating host immunity. Recent research has revealed a variety of natural products derived from TCM showing significant antimicrobial effects on antibiotic-resistant strains of P. aeruginosa alone or combined with antibiotics in vitro or in animal models, suggesting that TCM is a promising complementary and alternative therapeutic approach for treatment of chronic P. aeruginosa infections. This review summarizes the recent findings attempting to dissect the mechanisms of TCM combating P. aeruginosa infections and highlights the molecular targets of TCM on P. aeruginosa and host.

Abstract
Dabieshan tick virus (DTV) is a novel tick-borne virus with the potential to infect both animals and humans. It has been confirmed that DTV is widely distributed in Shandong and Zhejiang Provinces. In this study, a total of 389 ticks were sampled from Honghe city of Yunnan Province and Bijie city of Guizhou Province, and then divided into 148 pools according to the location and species. QRT-PCR and nested PCR were performed to confirm the presence of DTV. The results showed a minimum infection rate of 2.43% (5/206) in Yunnan Province and 3.28% (6/183) in Guizhou Province, respectively. Interestingly, DTV was identified in Rhipicephalusmicroplus for the first time besides Haemaphysalis longicornis. Phylogenetic analysis showed that DTV from Yunnan and Guizhou Provinces shared over 94% identity with isolates derived from Hubei and Shandong Provinces, and DTV was relatively conservative in evolutionary dynamics. These findings provide molecular evidence of Dabieshan tick virus in different species of ticks from unrecognized endemic regions and suggest that DTV may be widely prevalent in southwestern China.

Abstract
Fat deposition is an important economic trait in farm animals. However, it is difficult to genetically improve intramuscular fat deposition via trait-based cattle breeding. The main objectives of this study were to analyze the factors about beef flavor, and to detect functional microRNA (miRNA, miR) associated with intramuscular fat deposition in Yanbian cattle. Longissimus dorsi samples from six steers were separated into high- and low-fat groups (n = 3 each) based on the marbling score, and transcriptomic analysis was performed using miRNA sequencing. A total of 33 miRNAs and 38 genes were found to be differentially expressed in the high- and low-fat groups. Quantitative real-time polymerase chain reaction was performed to validate the sequencing results. Integrated miRNA-mRNA analysis revealed that miRNA-associated target genes were primarily associated with skeletal muscle development. However, some of the miRNAs (miR-424 etc.) and genes (ATF3 etc.) were also associated with fat metabolism. A targeted relationship between miR-22-3p and the WFIKKN2 gene and its involvement in adipocyte differentiation were confirmed experimentally. The study findings may provide potential candidate molecular targets for the selection of cattle with improved meat quality.

Abstract
Epidermolysis bullosa encompasses a group of inherited blistering skin disorders. The pathogenic mutations in 10–25% of patients with epidermolysis bullosa have not been identified by Sanger sequencing. The aims of this study were to identify the pathogenic sequence alterations in a large cohort of Chinese patients with epidermolysis bullosa and to clarify the relationship between clinical phenotypes and genotypes. Whole-exome sequencing was performed on 44 pedigrees and 13 sporadic cases. The results were further confirmed by Sanger sequencing. In total, 52 mutations, comprising 19 novel and 33 previously reported mutations, were identified in 5 genes, with a mutation detection rate of 100%. A relationship between subtypes and pathogenic genes was established: 12 cases of epidermolysis bullosa simplex were associated with mutations in KRT5/14 and PLEC; one case of junctional epidermolysis bullosa carried mutations in ITGB4; and 44 cases of dystrophic epidermolysis bullosa were caused by mutations in COL7A1. The results of this study support whole-exome sequencing as a promising tool in the genetic diagnosis of epidermolysis bullosa.

Abstract
Hailey-Hailey disease (HHD) is an autosomal dominant monogenic disease that is defective in the ATP2C1 gene. In previous studies, Sanger sequencing was the main method applied to detect mutations in HHD patients, and no mutations in the ATP2C1 gene were found in 12-55% of those reported. The aim of our study was to carry out whole exome sequencing (WES) for the HHD patients in whom efforts to identify mutations by Sanger sequencing had failed, and to find a new pathogenic gene. WES was performed using genomic DNA from 13 HHD patients and 364 in-house healthy controls. Potential pathogenic mutations were subsequently validated by Sanger sequencing. As a result, eight mutations in the ATP2C1 gene were identified using WES. In the remaining five patients, we found one mutation in the ATP2A2 gene which was the causal gene of Darier's disease. Four patients had no detectable mutations in ATP2C1 and the other ATPase genes. Together with our previous study in 2019, the total mutation rate was calculated to be 47/52 (90.4%). These findings demonstrate that WES is capable of improving the mutation detection sensitivity in HHD compared with Sanger sequencing.

Abstract
Background Circular RNA (circRNAs) and hypoxia have been found to play the key roles in the pathogenesis and progression of cancer including colorectal cancer (CRC). However, the expressions and functions of the specific circRNAs in regulating hypoxia-involved CRC metastasis, and the circRNAs that are relevant to regulate HIF-1α levels in CRC remain elusive. Methods qRT-PCR was used to detect the expression of circRNAs and mRNA in CRC cells and tissues. Fluorescence in situ hybridization (FISH) was used to analyze the location of circ-ERBIN. Function-based experiments were performed using circ-ERBIN overexpression and knockdown cell lines in vitro and in vivo, including CCK8, colony formation, EdU assay, transwell, tumor growth and metastasis models. Mechanistically, luciferase reporter assay, western blots and immunohistochemical stainings were performed. Results Circ-Erbin was highly expressed in the CRC cells and Circ-Erbin overexpression facilitated the proliferation, migration and metastasis of CRC in vitro and in vivo. Notably, circ-Erbin overexpression significantly promoted angiogenesis by increasing the expression of hypoxia induced factor (HIF-1α) in CRC. Mechanistically, circ-Erbin accelerated a cap-independent protein translation of HIF-1α in CRC cells as the sponges of miR-125a-5p and miR-138-5p, which synergistically targeted eukaryotic translation initiation factor 4E binding protein 1(4EBP-1). Conclusions Our findings uncover a key mechanism for circ-Erbin mediated HIF-1α activation by miR-125a-5p-5p/miR-138-5p/4EBP-1 axis and circ-ERBIN is a potential target for CRC treatment.

Abstract
Abstract
Background
Aortic valve disease is the most common valvular heart disease leading to valve replacement. The efficacy of pharmacological therapy for aortic valve disease is limited by the high mechanical stress at the aortic valves impairing the binding rate. We aimed to identify nanoparticle coating with entire platelet membranes to fully mimic their inherent multiple adhesion mechanisms and target the sclerotic aortic valve of apolipoprotein E-deficient (ApoE−/−) mice based on their multiple sites binding capacity under high shear stress.
Methods
Considering the potent interaction of platelet membrane glycoproteins with components present in sclerotic aortic valves, platelet membrane-coated nanoparticles (PNPs) were synthetized and the binding capacity under high shear stress was evaluated in vitro and in vivo.
Results
Compared with PNPs bound intensity in the static station, 161%, 59%, and 39% of attached PNPs remained adherent on VWF-, collagen-, and fibrin-coated surfaces under shear stress of 25dyn/cm2 respectively. PNPs demonstrated effectively adhering to von Willebrand factor, collagen and fibrin under shear stresses in vitro. In an aortic valve disease model established in ApoE−/− mice, PNPs group exhibited significant increase of accumulation in the aortic valves compared with PBS and control NP group. PNPs displayed high degrees of proximity or co-localization with vWF, collagen and fibrin, which exhibited good targeting to sclerotic aortic valves by mimicking platelet multiple adhesive mechanisms.
Conclusion
PNPs could provide a promising platform for the molecular diagnosis and targeting treatment of aortic valve disease.

Abstract
The cutaneous manifestations of COVID‐19 patients have been increasingly reported, but not summarized, and the potential mechanisms remain to be investigated. Herein, we performed a comprehensive review of literatures (from inception to 30 May 2020) using PubMed, CNKI, medRxiv and bioRxiv with the terms “((novel coronavirus) OR (2019 novel coronavirus) OR (2019‐nCoV) OR (Coronavirus disease 2019) OR (COVID‐19) OR (SARS‐CoV‐2)) AND ((Dermatology) OR (skin) OR (rash) OR (cutaneous))” and “((ACE2) OR (Angiotensin‐converting enzyme)) AND ((skin) OR (epidermis) OR (dermis)).” Totally, 44 articles met the inclusion criteria. A total of 507 patients with cutaneous manifestations were summarized, and 96.25% patients were from Europe. The average age of the patients was 49.03 (range: 5–91) with a female ratio of 60.44%. The skin lesions were polymorphic, and erythema, chilblain‐like and urticarial lesions were most common, occurring on an average of 9.92 days (range: 1–30) after the onset of systemic symptoms. The receptor of SARS‐CoV‐2, ACE2, was found to be expressed on skin, mainly on keratinocytes. Our review systematically presented the clinical characteristics of 507 patients and showed that skin might be the potential target of the infection according to ACE2 expression. More work should be done to better understand the underlying pathogenesis.

Abstract
AIM Research on prevention and cure of banana wilt is important to ensure the healthy development of the banana industry. In this study, antifungal mechanism of Streptomyces ma. FS-4 on fusarium wilt of banana was investigated. METHODS AND RESULTS The physiological strain of banana fusarium pathogen Fusarium oxysporum f. sp. cubense Race 4 (FOC.4) was used as the target fungus, and the antifungal mechanism of the crude extract of Streptomyces ma. FS-4 was investigated. Eighteen different compounds identified by gas chromatography-mass spectrometry were composed of aldehydes, methyl, hydrocarbons, amides, esters and acids. FS-4 significantly inhibited the spore germination of the target fungi, with an EC50 of 22·78 μg ml-1 . After treatment with 100 μg ml-1 FS-4 crude extract, the N-acetylglucosamine content in the mycelium increased 1·95-fold. However, the extract had no significant effect on β-1,3-glucanase. At the FS-4 crude extract dose of 100 μg ml-1 , the total sugar and protein contents decreased by 28·6 and 29·1% respectively, and the fat content was 41·3%. FS-4 significantly inhibited the activity of the mitochondrial complex III of Foc4, which was reduced by 52·45%. Moreover FS-4 reduced the activity of succinate dehydrogenase, a key enzyme in the Krebs cycle, by 60·2%. However, FS-4 had no significant effect on malate dehydrogenase. The membrane potential on the mitochondrial inner membrane was significantly reduced at the test concentration of 100 μg ml-1 . ROS gradually accumulated in the Foc4 hypha, and the burst was 3·97 times higher than the control. CONCLUSIONS This study demonstrated that the antifungal mechanism of Streptomyces ma. FS-4 against Foc4 includes the destruction of the plasma membrane and mitochondrial dysfunction and finally induction of cell apoptosis. SIGNIFICANCE AND IMPACT OF THE STUDY These results may indicate the prevention and control of banana wilt, which is of great significance to the healthy development of banana industry system.

Abstract
BACKGROUND DENV is the most globally prevalent mosquito-transmitted virus. Induction of a broadly and potently immune response is desirable for dengue vaccine development. METHODS Several formulations of secreted tetravalent EDIII protein containing different amounts of antigen from eukaryotic cells were used to evaluate the immune responses in mice. RESULTS We demonstrated that the tetravalent protein induced humoral immunity against all four serotypes of DENV, even at the lowest dose assayed. Besides, cellular immunities against DENV-1 and DENV-2 were elicited by medium dose group. Importantly, the immune responses induced by the tetravalent protein were functional in clearing DENV-2 in circulation of mice. CONCLUSIONS We believe that the tetravalent secreted EDIII protein is a potential vaccine candidate against DENV and suggest further detailed studies of this formulation in nonhuman primates.

Abstract
The Chinese National Twin Registry (CNTR) currently includes data from 61 566 twin pair from 11 provinces or cities in China. Of these, 31 705, 15 060 and 13 531 pairs are monozygotic, same-sex dizygotic and opposite-sex dizygotic pairs, respectively, determined by opposite sex or intrapair similarity. Since its establishment in 2001, the CNTR has provided an important resource for analysing genetic and environmental influences on chronic diseases especially cardiovascular diseases. Recently, the CNTR has focused on collecting biologic specimens from disease-concordant or disease-discordant twin pairs or from twin pairs reared apart. More than 8000 pairs of these twins have been registered, and blood samples have been collected from more than 1500 pairs. In this review, we summarize the main findings from univariate and multivariate genetic effects analyses, gene-environment interaction studies, omics studies exploring DNA methylation and metabolomic markers associated with phenotypes. There remains further scope for CNTR research and data mining. The plan for future development of the CNTR is described. The CNTR welcomes worldwide collaboration.

Abstract
Abstract
Pseudomonas aeruginosa is an opportunistic pathogen that is the major cause of nosocomial infections in cystic fibrosis patients and immunocompromised individuals. The molecular mechanisms governing immune responses to P. aeruginosa infection remain incompletely defined. Early Growth Response 1 (Egr-1) is a zinc-finger transcription factor that binds to the GC-rich DNA consensus sequences in the promotor of target genes, important for cell growth, differentiation and survive. Aberrant expression of Egr-1 has been implicated in many inflammatory diseases. In this study, we demonstrate that Egr-1 deficiency protects host against P. aeruginosa infection in a mouse model of acute bacterial pneumonia. Egr-1 expression was rapidly and transiently induced both in vitro and in vivo upon P. aeruginosa infection. Egr-1-deficient mice displayed decreased disease score, reduced systemic levels of proinflammatory cytokines and impaired NF-κB and NFAT activation compared to wild-type mice. Interestingly, Egr-1 deficiency leads to enhanced bacterial clearance and increased nitric oxide production in lung whereas it has no impact on neutrophil recruitment. Further studies revealed that Egr-1-deficient neutrophils displayed elevated bacterial killing ability. Altogether, these findings suggest that Egr-1 promotes inflammatory responses by enhancing NF-κB and NFAT activation and plays a detrimental role in host defense against P. aeruginosa lung infection by negatively regulating nitric oxide production for bacterial clearance.

Abstract
Pseudomonas aeruginosa is an opportunistic pathogen that is a leading cause of morbidity and mortality in cystic fibrosis patients and immunocompromised individuals. Eradication of P. aeruginosa has become increasingly difficult due to its remarkable capacity to resist antibiotics. Strains of Pseudomonas aeruginosa are known to utilize their high levels of intrinsic and acquired resistance mechanisms to counter most antibiotics. In addition, adaptive antibiotic resistance of P. aeruginosa is a recently characterized mechanism, which includes biofilm-mediated resistance and formation of multidrug-tolerant persister cells, and is responsible for recalcitrance and relapse of infections. The discovery and development of alternative therapeutic strategies that present novel avenues against P. aeruginosa infections are increasingly demanded and gaining more and more attention. Although mostly at the preclinical stages, many recent studies have reported several innovative therapeutic technologies that have demonstrated pronounced effectiveness in fighting against drug-resistant P. aeruginosa strains. This review highlights the mechanisms of antibiotic resistance in P. aeruginosa and discusses the current state of some novel therapeutic approaches for treatment of P. aeruginosa infections that can be further explored in clinical practice.

Abstract
Platelets have been implicated in pulmonary inflammation following exposure to bacterial stimuli. The mechanisms involved in the platelet-mediated host response to respiratory bacterial infection remain incompletely understood. In this study, we demonstrate that platelet-derived chemokine (C-X-C motif) ligand 4 (CXCL4) plays critical roles in a mouse model of acute bacterial pneumonia using Pseudomonas aeruginosa. Platelets are activated during P. aeruginosa infection, and mice depleted of platelets display markedly increased mortality and impaired bacterial clearance. CXCL4 deficiency impairs bacterial clearance and lung epithelial permeability, which correlate with decreased neutrophil recruitment to BALF. Interestingly, CXCL4 deficiency selectively regulates chemokine production, suggesting that CXCL4 has an impact on other chemokine expression. In addition, CXCL4 deficiency reduces platelet-neutrophil interactions in blood following P. aeruginosa infection. Further studies revealed that platelet-derived CXCL4 contributes to the P. aeruginosa-killing of neutrophils. Altogether, these findings demonstrate that CXCL4 is a vital chemokine that plays critical roles in bacterial clearance during P. aeruginosa infection through recruiting neutrophils to the lungs and intracellular bacterial killing.

Abstract
Objective: To explore the expression of microRNA-155 in colonic mucosa and peripheral blood in patients with inflammatory bowel disease(IBD), and to examine the clinical value and significance of microRNA-155 in the diagnosis of IBD. Methods: Quatitative reverse-transcription PCR was performed to detect the expression of microRNA-155 in 20 patients with Crohn disease(CD), 21 patients with ulcerative colitis (UC), 18 patients with IBD type unclassified(IBDU), 25 healthy people(control group), 12 patients with infection colitis and 19 patients with ischemia colitis.Receiver operating characteristic (ROC) curve was performed to analyze the clincal value of microRNA-155 in diagnosis of IBD. Results: The expression of microRNA-155 in colonic mucosa in CD, UC and IBDU group was significantly higher than that in control group(P<0.05). MicroRNA-155 expression was also significantly higher in UC group in comparison to CD group (35.4±3.0 vs 18.6±5.9, P<0.01), IBDU group in comparison to CD group (23.0±3.7 vs 18.6±5.9, P<0.05) and UC group in comparison to IBDU group (35.4±3.0 vs 23.0±3.7, P<0.01). The plasma level of microRNA-155 in UC group (55.6±2.5) and IBDU group (48.1±6.2) was significantly higher than that in control group(P<0.05), while no significant difference in CD group was observed when compared with control group(P>0.05). ROC curve shows an AUC of 0.83 and 95%CI of 0.679-0.986 of microRNA-155 expression in colonic mucosa.The sensitivity and specificity of microRNA-155 expression in colonic mucosa in diagnosis of IBD was 68.4% and 78.6%, respectively. Conclusions: MicroRNA-155 showed high expression in colonic mucosa and peripheral blood in patients with IBD.MicroRNA-155 shows promise as a biomarker in diagnosis of IBD.Furthermore, the aberrant expression indicates that microRNA-155 may be involved in pathogenesis and progression of IBD.

Abstract
Toll-like receptors (TLRs) recognize the conserved molecular patterns in microorganisms and trigger myeloid differentiation primary response 88 (MyD88) and/or TIR-domain-containing adapter-inducing interferon-β (TRIF) pathways that are critical for host defense against microbial infection. However, the molecular mechanisms that govern TLR signaling remain incompletely understood. Regulator of calcineurin-1 (RCAN1), a small evolutionarily conserved protein that inhibits calcineurin phosphatase activity, suppresses inflammation during Pseudomonas aeruginosa infection. Here, we define the roles for RCAN1 in P. aeruginosa lipopolysaccharide (LPS)-activated TLR4 signaling. We compared the effects of P. aeruginosa LPS challenge on bone marrow-derived macrophages from both wild-type and RCAN1-deficient mice and found that RCAN1 deficiency increased the MyD88-NF-κB-mediated cytokine production (IL-6, TNF and MIP-2), whereas TRIF-interferon-stimulated response elements (ISRE)-mediated cytokine production (IFNβ, RANTES and IP-10) was suppressed. RCAN1 deficiency caused increased IκBα phosphorylation and NF-κB activity in the MyD88-dependent pathway, but impaired ISRE activation and reduced IRF7 expression in the TRIF-dependent pathway. Complementary studies of a mouse model of P. aeruginosa LPS-induced acute pneumonia confirmed that RCAN1-deficient mice displayed greatly enhanced NF-κB activity and MyD88-NF-κB-mediated cytokine production, which correlated with enhanced pulmonary infiltration of neutrophils. By contrast, RCAN1 deficiency had little effect on the TRIF pathway in vivo. These findings demonstrate a novel regulatory role of RCAN1 in TLR signaling, which differentially regulates MyD88 and TRIF pathways.

Abstract
BACKGROUND There is evidence that birth size is positively associated with height in later life, but it remains unclear whether this is explained by genetic factors or the intrauterine environment. AIM To analyze the associations of birth weight, length and ponderal index with height from infancy through adulthood within mono- and dizygotic twin pairs, which provides insights into the role of genetic and environmental individual-specific factors. METHODS This study is based on the data from 28 twin cohorts in 17 countries. The pooled data included 41,852 complete twin pairs (55% monozygotic and 45% same-sex dizygotic) with information on birth weight and a total of 112,409 paired height measurements at ages ranging from 1 to 69 years. Birth length was available for 19,881 complete twin pairs, with a total of 72,692 paired height measurements. The association between birth size and later height was analyzed at both the individual and within-pair level by linear regression analyses. RESULTS Within twin pairs, regression coefficients showed that a 1-kg increase in birth weight and a 1-cm increase in birth length were associated with 1.14-4.25 cm and 0.18-0.90 cm taller height, respectively. The magnitude of the associations was generally greater within dizygotic than within monozygotic twin pairs, and this difference between zygosities was more pronounced for birth length. CONCLUSION Both genetic and individual-specific environmental factors play a role in the association between birth size and later height from infancy to adulthood, with a larger role for genetics in the association with birth length than with birth weight.
