In view of the practical problems of high energy consumption, high treatment cost and complicated operation caused by the current high-concentration ammonia nitrogen removal method in coal chemical wastewater, such as the steaming ammonia and stripping method, the natural zeolite was modified to investigate the adsorption and chemical regeneration performance of the modified zeolite on the high concentration of ammonia nitrogen in coal chemical wastewater. The results showed that the specific surface area of zeolite increased from 18.541 m2/g to 32.198 m2/g after the synergistic modification processes by heat treatment at 300 ℃ and brine leaching in 1.5 mol/L NaCl solution. Compared with the natural zeolite, the adsorption capacity increased by 74% and the removal efficiency of NH4+ also reached to 88.94%. The adsorption kinetic and isotherm analysis showed that the adsorption process of high-concentration NH4+ by modified zeolite in coal chemical wastewater was consistent with the chemical multilayer adsorption process. In addition, 0.100 mol/L NaClO solution had the best regeneration effect for the modified zeolite, with the regeneration rate as high as 94.5%, and the regenerated NH4+ was converted into non-toxic and harmless N2, which realized the prospects of high-efficiency and sustainable regeneration of zeolite without secondary pollution.

【Objective】 Nonpoint source pollution poses a significant threat to the surface water environment, particularly in agricultural systems. Reconstructed wetlands are an environmentally friendly method to mitigate nonpoint source pollution. This paper investigates the efficacy of plants and their growing medium in removing pollutants from farmland receding water. 【Method】 The experiment was conducted in a subsurface-flow wetland and an ecology surface flow wetland at Bapaigan region along the bank of Duliujian River. We measured the impact of aquatic plant species, planting density, matrix materials and filling rate, and hydraulic retention time of water in the wetland on purification of the water. 【Result】 Among all treatments we compared, the combination of plant species of Scirpus tabernaemontani+ Iris tectorum and matrix of zeolite+ volcanic rock was most effective to purify the receding water, as they nurtured a microbial community which increased denitrification and dephosphorization. Keeping the hydraulic retention time 3 day and running 10 consecutive cycles can remove ammonia nitrogen, total phosphorus and chemical oxygen demand (COD) contents by 95.74%, 49.94% and 89.03%, respectively. 【Conclusion】 Following the implementation of the Bapaigan constructed wetland, the plants, substrate medium and their associated microbiome were effective to remove the pollutants from the receding water, with the effluent water quality reaching Class V standard for surface water. These findings have important implications for remediating farmland runoff using constructed wetlands in north China.

Abstract Objective To investigate the differences in the niacin skin flushing response of adolescent depressed patients and healthy adolescents and its diagnostic value in adolescent depression. Methods Thirty-eight cases of acute episodes of depression in unmedicated adolescents and 47 age- and sex-matched healthy controls were included as study subjects, and sociodemographic and clinical data were collected, all of which were stimulated with six concentration gradients (up to 60 mmol/L, followed by sequential 3-fold gradient dilution to a minimum of 0.25 mmol/L) of niacin solution on the forearm skin, and the skin flushing area was applied as an assessment index. Results The total area of redness of the skin in response to niacin was significantly lower in the adolescent depression group than in the healthy adolescent group (Z=-3.36, p = 0.001) and was able to distinguish the adolescent depression group from the healthy adolescent group (area under curve = 0.713, sensitivity 51.1%, specificity 83.2%). Conclusions Niacin sensitivity is reduced in adolescent depressed patients, and the niacin skin flush response has potential clinical value as a diagnostic biomarker for adolescent depression.

The physiological inhibitors of soluble epoxide hydrolase (sEH) have significant efficacy in the treatment of hypertension, inflammation, cardiovascular disease and diabetes. In this study, a Hypogen pharmacophore was developed using Atlantic cod peptide and was used to screen for bioactive peptides with tryptophan and sEH inhibitory activity by molecular docking. Bioactive peptide sequences were prepared by solid-phase synthesis, and their in vitro sEH inhibitory activity was determined by high performance liquid chromatography (HPLC). The results showed that the tetrapeptide (PLLW) selected by the optimal pharmacophore model had the best Fit value (9.053) and LibDock score (147.807), and its half-maximal inhibitory concentration (IC50) was 506.66 μmol/L. The molecular docking results showed that PLLW competed with physiological substrates to bind to the active site of sEH through hydrogen bonding and hydrophobic interactions. This study provides a new idea for the screening and mechanistic study of sEH inhibitors in foodborne mixed systems, and also provides a suitable model for the development of sEH inhibitor products.

Compared with English text which is naturally composed of words,Chinese text has no word delimiters,so the combination of Chinese characters is more flexible,and it's more difficult to determine the entity boundaries in Chinese named entity recognition(NER).Current mainstream methods transform the NER task into a sequence labeling task.This paper studies the predicted label sequence under the BIOES tag scheme and calculates the entity boundary accuracy by separately considering the entity head label B or tail label E,which shows that increasing the boundary accuracy can further improve the accuracy of entity recognition.We expand the boundaries of entities with continuous labels,use the label type of the last character of the entity to correct the entity type,and use the word segmentation information to fill in the entity with incomplete labels.Finally,this paper proposes a BIO+ES labeling scheme that adds boundary labels to distinguish non-entity characters at entity boundaries and further improves the performance of Chinese NER.

In the present research work, the 2.25Cr1Mo0.25V steel plates with a thickness of 112 mm were welded using the multi-pass submerged automatic arc welding process. The creep specimens were prepared from the base metal (BM) and weld metal (WM) in the welded joint after heat treatment process. The uniaxial creep tests were performed to investigate the creep deformation and rupture behaviors at 550°C under different applied stress levels. The microstructure and fracture surface morphology of crept BM and WM samples were also characterized using the scanning electron microscope with energy-dispersive X-ray spectroscopy. The results showed that typical three-stage creep deformation curves are observed in both BM and WM specimens, and the BM exhibits a faster deformation rate than the WM. Both the creep rupture time and uniaxial creep ductility are found to be increased with a decrease in applied stress. Furthermore, the relationship between the minimum creep rate and time to rupture of both BM and WM samples was obtained, and it can be described using a unified Monkman–Grant equation. In addition, it is found that the creep fractures of the BM and WM are a transgranular ductile failure. The creep damages of both materials are mainly associated with the microstructural degradations, that is, the initiation and coalescence of creep cavities at second phase particles such as carbide and inclusion particles along the loading direction.

The ΔN6 truncation is the main posttranslational modification of β2-microglobulin (β2M) found in dialysis-related amyloid. Investigation of the interaction of wild-type (WT) β2M with N-terminally truncated variants is therefore of medical relevance. However, it is unclear which residues among the six residues at the N-terminus are crucial to the interactions and the modulation of amyloid fibril propagation of β2M. We herein analyzed homo- and heterotypic seeding of amyloid fibrils of WT human β2M and its N-terminally-truncated variants ΔN1 to ΔN6, lacking up to six residues at the N-terminus. At acidic pH 2.5, we produced amyloid fibrils in vitro from recombinant, WT β2M and its six truncated variants, and found that ΔN6 β2M fibrils exhibit a significantly lower conformational stability than WT β2M fibrils. Importantly, under more physiological conditions (pH 6.2), we assembled amyloid fibrils in vitro only from recombinant, ΔN4, ΔN5, and ΔN6 β2M but not from WT β2M and its three truncated variants ΔN1 to ΔN3. Notably, the removal of the six, five or four residues at the N-terminus leads to enhanced fibril formation, and homo- and heterotypic seeding of ΔN6 fibrils strongly promotes amyloid fibril formation of WT β2M and its six truncated variants, including at more physiological pH 6.2. Collectively, these results demonstrated that the residues 4 to 6 at the N-terminus particularly modulate amyloid fibril propagation of β2M and the interactions of WT β2M with N-terminally truncated variants, potentially indicating the direct relevance to the involvement of the protein’s aggregation in dialysis-related amyloidosis.

Abstract Background We performed a meta-analysis sought to investigate the risk of stroke with antiplatelet and anticoagulant therapies among patients with coronary artery disease (CAD). Methods We searched PubMed, EMBASE, and Cochrane Library for randomized controlled trials from January 1995 to March 2020. Studies were retrieved if they reported data of stroke for patients with CAD and were randomized to receive intensive versus conservative antithrombotic therapies, including antiplatelet and oral anticoagulant (OAC). Analyses were pooled by random-effects modeling. A total of 42 studies with 301,547subjects were enrolled in this analysis. Results Intensive antithrombotic therapy significantly reduced risk of all stroke (RR 0.86, 95% CI 0.80–0.94) and ischemic stroke (RR 0.80, 95% CI 0.71–0.91), but increased risk of hemorrhagic stroke (RR 1.36, 95% CI 1.00–1.86) and intracranial hemorrhage (RR 1.46, 95% CI 1.17–1.81). Subgroup analyses indicated that OAC yields more benefit to all stroke than antiplatelet therapy (OAC: RR 0.73, 95% CI 0.58–0.92; Antiplatelet: RR 0.90, 95% CI 0.83–0.97; Between-group heterogeneity P value = 0.030). The benefit of antiplatelet therapy on all stroke and ischemic stroke were mainly driven by the studies comparing longer versus shorter duration of dual antiplatelet therapy (All stroke: RR 0.86, 95% CI 0.78–0.95; ischemic stroke: RR 0.84, 95% CI 0.75–0.94). Conclusions Among CAD patients who have already received antiplatelet therapy, either strengthening antiplatelet or anticoagulant treatments significantly reduced all stroke, mainly due to the reduction of ischemic stroke, although it increased the risk of hemorrhagic stroke and intracranial hemorrhage. OAC yields more benefit to all stroke than antiplatelet therapy.

Nitrogen fertiliser application can effectively increase the net primary productivity (NPP) of agriculture and grassland ecosystems. There is some long-term retention of nitrogen applied to soils, but much is lost to runoff, to in situ denitrification and to gaseous forms of nitrogen (such as NH3 and NOX). So it is particularly important to improve nitrogen-use efficiency through various ways. Therefore, the effects of the urea with urease inhibitor N-(n-butyl)thiophosphoric triamide (NBPT) or/and nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) on the NPP, NH3 and 15N recovery were researched on the alpine grassland ecosystem. The results showed that the addition NBPT to urea can significantly reduce the cumulative NH3 emission of urea-N compared with urea alone. The NBPT or DMPP addition to urea significantly increased the above-ground NPP and the economic efficiency. Urea added to NBPT or NBPT+DMPP could increase the 15N recovery rate of plant and soil (0-40 cm) by nearly 20%. The results indicated that urea combined with DMPP may be a good way to nitrogen fertiliser retention and reduction of NH3 emission for the alpine grassland of the northeast of the Qinghai-Tibet Plateau.

Atlantic Giant (AG) pumpkin (Cucurbita maxima) produces the world’s largest fruit. Elucidating the molecular mechanism of AG fruit formation is of scientific and practical importance. In this research, genome-wide resequencing of an F2 population produced by a cross between AG and its small-fruit ancestor Hubbard was used to identify quantitative trait loci (QTLs) and candidate genes. Transgressive segregation of fruit size-related traits was observed in the F2 population, suggesting that fruit size was a quantitative trait controlled by multiple genes. A genetic map with an average physical distance of 154 kb per marker was constructed, and 13 QTLs related to fruit size were identified using bin-map construction. RNA sequencing analysis revealed that pathways associated with assimilate accumulation into the fruit, including carbohydrate metabolism, were significantly enriched in differentially expressed genes. According to the predicted impact of mutation on the biological function of certain proteins, 13 genes were selected as candidate genes associated with fruit size, among which two phytohormone-related genes, CmaCh17G011340 (a flavin-containing monooxygenase) and CmaCh04G029660 (a leucine-rich repeat protein kinase) were chosen for further investigation. Finally, one insertion-deletion (inDel) and three single nucleotide polymorphisms (SNPs) were successfully transformed to Kompetitive Allele-Specific PCR (KASP) markers. The novel QTLs and candidate genes identified provide insights into the genetic mechanism of large fruit formation of AG, and the genetic map and tightly linked KASP markers developed in this study can be employed for marker-assisted breeding to alter fruit size of C. maxima.

Objective To evaluate the effect of curcumin on wound healing in deep tissue pressure injury(DTPI) induced by ischemia-reperfusion in mice. Methods Mice were randomly divided into control group (Con), model group (Mod), 4 and 8 mg/kg curcumin treatment group (Cur 4, Cur 8), 10 mice in each group. A deep tissue pressure injury model was established by magnet compression. The wounds tissue was injected with curcumin every 48 hours and photographed to observe the wound healing. HE staining was used to observe the pathological changes of wound healing. Real-time PCR was used to detect the mRNA expression of TNF-α, IL-6, IL-10, VEGF-α and TGF-β. Western blot was used to detect the expression of VEGF-α, TGF-β, Stat3 and p-Stat3. Results Compared with the control group, the wound in the model group gradually deteriorated, and the pathological changes were obvious. Compared with the model group, the wound healing of the Cur 8 group was significantly accelerated (P＜0.05). Compared with the model group, the inflammatory cell infiltration was reduced and the neovascular density was increased in the Cur 8 group. The mRNA expression of TNF-α and IL-6 in the wound tissues of the Cur 8 group was less than those in the model group, while the expression of IL-10, VEGF-α and TGF-β was higher than those in the model group (P＜0.05). The expression of VEGF-α, TGF-β and p-Stat3 in Cur 8 group was higher than those in model group (P＜0.05). Conclusions Curcumin administration can alleviate DTPI of mice induced by ischemia-reperfusion, and its mechanism may be related to the inhibition of inflammatory response and promotion of angiogenesis.

Objective To investigate the effects of platinum-based first-line chemotherapy combined with irinotecan versus with etoposide on brain metastasis of small cell lung cancer patients (SCLC). Methods A retrospective analysis was carried out in 126 SCLC patients without brain metastases admitted to our hospital from November 2011 to July 2018, including 84 patients receiving irinotecan chemotherapy in the first line (IP group), and 42 patients undergoing etoposide treatment in the first line (EP group), both based on platinum treatment. Objective response rate (ORR), disease control rate (DCR), and median progression-free survival (PFS), and cumulative incidence of central nervous system (CNS) and non-CNS progression after first-line treatment were compared between the 2 groups. Results For the IP group and the EP group, the ORR were 79.8% and 76.2%, respectively (P=0.645), and the DCR was 89.3% and 92.9%, respectively (P=0.748). The median PFS was 7.500±0.779 (5.974~9.026) months in the IP group, and 5.500±0.648 (4.230~6.770) months in the EP group, and statistical difference was seen between them (P=0.015). Compared with the EP group, the risk ratios of brain metastasis in IP patients with limited and extensive stages of SCLC were 0.270 (95%CI: 0.096~0.760, P=0.013) and 0.914 (95%CI: 0.281~2.973, P=0.881). In 3 months after treatment, the cumulative incidence of brain metastases in patients with limited stage was lower in the IP group than the EP group, and the incidence at 1 year was 14.3% and 31.8%, respectively. Conclusion IP chemotherapy delays the brain metastasis of SCLC patients when compared with EP treatment.

In the process of rapid social and economic development, the demand for the oil of related industries is more and more large. The continuous increase of oil exploitation is causing some oil fields to gradually enter the period of special high water cut development and increasing the difficulty of oil exploitation. Therefore, how to improve oil recovery is the key question that relevant personnel think and solve. Based on this, this paper mainly describes the channel sand body description technology combined with well shock, and analyzes the reservoir description method combined with well shock combined with the general situation of an oilfield working area, aiming at improving the prediction accuracy of sand body in dense well pattern area and effectively guiding the development and adjustment of potential excavation work.

Backgrounds: Omentin-1 is a novel cytokine that is primarily released by the epicardial adipose tissue. Molecular structure analysis revealed that it contained a fibrinogen-like domain. Clinical studies have demonstrated that the expression of omentin-1 is tightly associated with the development of cardiovascular diseases, but the receptor by which omentin-1 modulates macrophage function has not been identified yet.Objective: This study sought to investigate the effect of omentin-1 on already-established atherosclerosis (AS) lesions in both ApoE−/− and Ldlr−/− mice and further, study its underlying mechanisms.Methods and Results: We investigated the effect of omentin-1 on the plaque phenotype by implanting a minipump in ApoE−/− and Ldlr−/− mice. In vivo studies showed that the infusion of omentin-1 increased the collagen content and mitigated the formation of the necrotic core in both animal models. Immunohistochemistry and immunofluorescence analysis revealed that omentin-1 suppressed inflammatory cytokines expression, macrophage infiltration, and apoptosis within the plaque. An immunoprecipitation experiment and confocal microscopy analysis confirmed the binding of omentin-1 to the integrin receptors αvβ3 and αvβ5. The cell studies demonstrated that omentin-1 suppressed the apoptosis and inflammatory cytokines expression induced by the oxidized low-density lipoprotein in the macrophage. In addition, omentin-1 promoted the phosphorylation of the integrin-relevant signaling pathway as well as the Akt and AMPK in the macrophage. The addition of the inhibitor of the integrin receptor or interfering with the expression of the integrin subunit αv (ITGAV) both significantly abrogated the bioeffects induced by omentin-1. A flow cytometry analysis indicated that the antibodies against αvβ3 and αvβ5 had a competitive effect on the omentin-1 binding to the cell membrane.Conclusions: The administration of adipokine omentin-1 can inhibit the necrotic cores formation and pro-inflammatory cytokines expression within the AS lesion. The mechanisms may include the suppression of apoptosis and pro-inflammatory cytokines expression in the macrophage by binding to the integrin receptors αvβ3 and αvβ5.

Size is the most important quality attribute of giant pumpkin fruit. Different concentrations and application frequencies of α-naphthaleneacetic acid (NAA) and 24-epibrassinolide (EBR) were sprayed on the leaves and fruits of giant pumpkin at different growth stages to determine their effects and the mechanism responsible for fruit size increase. NAA+EBR application improved source strength, and further analysis indicated that NAA+EBR markedly boosted net photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr) and the expression level and activity of galactitol synthetase (GolS), raffinose synthetase (RS), and stachyose synthetase (STS), resulting in an increase in the synthesis of photoassimilate, especially stachyose. Concomitantly, NAA+EBR spray increased stachyose and sucrose contents throughout pumpkin fruit growth and the concentrations of glucose and fructose at 0 and 20 days post-anthesis (DPA) in peduncle phloem sap, implying that such treatment improved the efficiency of assimilate transport from the peduncle to the fruit. Furthermore, it improved the expression and activity of alkaline α-galactosidase (AGA), facilitating assimilate unloading, providing carbon skeletons and energy for fruit growth, and increasing fruit weight by more than 44.1%. Therefore, exogenous NAA and EBR increased source capacity, transportation efficiency, and sink strength, overall promoting the synthesis and distribution of photoassimilate, ultimately increasing fruit size.

The porous TiO2 powders were prepared by sol-gel method using titanium tetrachloride as titanium source, P123 as template agent and cyanamide as stabilizer agent, respectively. The porous TiN powders were synthesized via reduction and nitridation of the porous TiO2 powders at 900℃ in NH3. The phase composition and microstructure of the porous TiN powders were characterized by the XRD, SEM, BET, TEM and SAXD. The electrochemistry performance of the porous TiN powders was evaluated through the cyclic voltammetry, AC impedance and constant current charge-discharge techniques. The results show that the porous powders have approximate spherical particles with cubic TiN phase. Compared to the porous TiN powders without P123 adding, the mesopores with pore diameter range of 10-50nm increased in the porous TiN powders with P123 adding. There are also some pores with size range of 2-3nm. Meanwhile the porous TiN powders with P123 adding exhibit more ordered mesopores. This porous structure can improve the electrochemistry performance of the TiN powders. As a result, for the porous TiN powders without P123 adding, the specific capacitance is 81F·g-1. The internal resistance R1 is 1.1Ω, and the ion diffusion impedance W1 is 2.5Ω. For the porous TiN powders with P123 adding, the specific capacitance is increased to 95F·g-1, the R1 and W1 value are decreased to 0.9Ω and 0.06Ω, respectively.

A series of symmetric and asymmetric binuclear α-diimine nickel(II) complexes toward ethylene polymerization were successfully synthesized and characterized by 1HNMR. All the catalysts were typically activated with MAO and displayed good activity at room temperature under 1atm ethylene pressure. The symmetric catalyst containing isopropyl on ligand-activated with 500 equiv MAO produced high molecular weight polyethylene with a PDI=1.75, while the symmetric catalyst containing methyl on ligand produced relatively low molecular weight polyethylene with a PDI=1.74. By contrast, the molecular weight, branching density of resultant polymer produced by asymmetric catalyst decrease roughly somewhere between that of polymers prepared by two symmetric catalysts.

Due to the low neutron activity, the high thermal stability, and the good compression strength at elevated temperatures, medium-entropy Ta-Ti-V alloys have the application potential to be used in future nuclear engineering. According to experimental results, a special quasi-random structure (SQS) model and first-principles calculations are used to calculate the structural stability and the elasticity of the ternary single-phase body-centered cubic (BCC) Ta-Ti-V alloys with the compositions Ta24Ti14V16, Ta19Ti17V18, Ta16Ti21V17, Ta22Ti23V9, and Ta18Ti18V18. The mixing energy of five compositions is positive, which indicates that they are unstable at low temperature but stable at high temperature. Meanwhile, we predict the ability of elasticity in those five compositions, and the sequence of bulk modulus is Ta24Ti14V16 > Ta19Ti17V18 > Ta18Ti18V18 > Ta16Ti21V17 > Ta22Ti23V9 and ductility is Ta19Ti17V18 > Ta18Ti18V18 > Ta22Ti23V9 > Ta24Ti14V16 > Ta16Ti21V17. Additionally, the influence of the element content on elastic properties shows that the Ta content will increase the bulk modulus of the alloys, while Ti content decreases the bulk modulus. Higher V and Ti contents are beneficial to ductility, especially the V content. The higher Ta content will sharply reduce the ductility of the alloys. Our calculation has provided further theoretical mechanism for the Ta-Ti-V medium-entropy alloys (MEAs) preparation and development.

To ensure the safety and efficient operation of nuclear reactors, it is imperative to understand the effects of various dopants (Ti, Th, and Zr) on the solubility of the fission product Xe in UO2. In this study, Hubbard corrected density functional theory (DFT + U) and occupation matrix control were used to investigate the bulk and defect properties of UO2. The results show that the UO2-Ti system is more favorable for Xe dissolution in vacancies, whereas the UO2-Th system has little effect on the dissolution of Xe atoms. Th, Zr, and Ti inhibit the aggregation of Xe clusters, and Ti is the least favorable for the nucleation and growth of Xe clusters.

Aluminum (Al) can be easily contaminated or damaged after exposure in damp environments, which can adversely affect its aesthetic appearance and desired functionalities. To improve its corrosion resistance, a superhydrophobic coating was fabricated on Al by electrochemical anodization followed by modification with myristic acid. The surface morphology and chemical composition were characterized by using a field emission scanning electron microscope (FESEM) with attached energy dispersive X-ray spectrum (EDS). The surface wettability, mechanical stability as well as corrosion resistance were also investigated by contact angle measuring system, sandblasting test and electrochemical measurements. The results show that the optimal Al-based superhydrophobic coating with a static water contact angle of (155.2±0.5)° and a sliding angle of (3.5±1.3)° is obtained at the anodization voltage of 20V. The corresponding corrosion current density (Icorr) is reduced by 2 orders of magnitude and the corrosion potential (Ecorr) shifts from -0.629V to -0.570V compared to the bare Al substrate, indicating excellent corrosion resistance. Besides, the as-prepared optimal Al-based superhydrophobic coating also suggests good mechanical stability.

With the development of underground transportation, in order to reduce the impact on the surrounding environment and traffic, Hejiaying subway island station adopts the concealed excavation method. During the construction process, considering the construction method, tunnel layout, ventilation requirements, and the construction working face as a multi-conductor cave, more stringent requirements are put forward for the construction ventilation of the tunnel. Through the combination of theoretical calculation and numerical simulation, a ventilation method suitable for the actual construction conditions at the site was developed. After applying the scheme to practice, the feasibility of the scheme was verified through the determination of field data, and the improvement of the construction environment for tunnel personnel was achieved, which has certain reference value for similar projects.

Pampus fishes (Perciformes: Stromateidae) are important commercial species and include six valid species in China. The southern lesser pomfret (Pampus minor Liu and Li, 1998) is a species of Pampus for which knowledge is incomplete. This report confirms the occurrence of P. minor in the coastal waters of Wenzhou, China, by analyzing five specimens of P. minor obtained in Wenzhou in March 2019. Morphometric measurements and meristic counts were performed. The diagnostic morphological features of these species were consistent with those of the neotype specimen of P. minor and sufficient for separating the examined specimens from other Pampus species. This study was based on the Cytochrome Oxidase Subunit 1 (CO1) gene, which was sequenced for the purpose of identification. The genetic distances between P. minor and other Pampus species ranged from 13.4% to 15.5%, and the mean genetic distance within the P. minor group was 0.2%. Given that P. minor has not been reported in this region, our findings represent the first record from the coastal waters of Wenzhou and extend the distribution range of this species to the central and northern East China Sea. The reason for the observed northward migration of some P. minor individuals from their northernmost recorded habitat (Taiwan Strait) might be global warming. The collection of additional specimens is needed to further study the geographic limits of P. minor and its presumed northern expansion.
