Attenuation of the Activation of NLRP3 Inflammasome in Fibroblast Like Synoviocytes of Rheumatoid Arthritis by Baicalin through Regulating the Let-7i-3p/PI3K/Akt/NF-κB Signaling Axis

[Objectives]To study the effect and mechanism of baicalin on the activation of NLRP3 inflammasome in human fibroblast like synoviocytes of rheumatoid arthritis(HFLS-RA).[Methods]To confirm that baicalin alleviated the activation of NLRP3 inflammasome in HFLS-RA,the expression of NLRP3 before and after baicalin treatment was observed by immunofluorescence.Western blot was used to detect the protein expression of p-PI3K,p-Akt,NF-κB p65,NLRP3,ASC and caspase-1 after baicalin treatment for 48 h,and the contents of IL-1 and IL-18 in the supernatents were detected by ELISA.In order to explore the mechanism of baicalin alleviating the activation of NLRP3 inflammasome,the corresponding relationship between let-7i-3p and PIK3CA was verified by double luciferin and Westen blot analysis.The expression of let-7i-3p and PI3K before and after baicalin intervention was detected by RT-qPCR.let-7i-3p interference was used to verify whether baicalin mitigated the activation of enhanced NLRP3 inflammasome.[Results]Baicalin(50 and 100 mg/L)significantly reduced the activation of NLRP3 inflammasome,inhibited the protein expressions of p-PI3K,p-Akt,NF-κB p65,NLRP3,ASC and caspase-1,and the secretion of IL-1 and IL-18.let-7i-3p and PIK3CA had a targeted correspondence,and baicalin up-regulated the expression of let-7i-3p and down-regulated the expression of PIK3CA.Baicalin attenuated the activation of NLRP3 inflammasome enhanced by let-7i-3p interference.[Conclusions]Baicalin can up-regulate let-7i-3p expression,inhibit PI3K/Akt/NF-κB signal transduction,and thus reduce the activation of NLRP3 inflammasome in HFLS-RA.

Quantitative lithium substitution of carboxyl hydrogens in polyacrylic acid binder enables robust SiO electrodes with durable lithium storage stability

The design of advanced binders plays a critical role in stabilizing the cycling performance of large-volume-effect silicon monoxide(SiO)anodes.For the classic polyacrylic acid(PAA)binder,the self-association of-COOH groups in PAA leads to the formation of intramolecular and intermolecular hydrogen bonds,greatly weakening the bonding force of the binder to SiO surface.However,strengthening the binder-material interaction from the perspective of binder molecular regulation poses a significant challenge.Herein,a modified PAA-Li_(x)(0.25≤x≤1)binder with prominent mechanical properties and adhesion strength is specifically synthesized for SiO anodes by quantitatively substituting the carboxylic hydrogen with lithium.The appropriate lithium substitution(x=0.25)not only effectively increases the number of hydrogen bonds between the PAA binder and SiO surface owing to charge repulsion effect between ions,but also guarantees moderate entanglement between PAA-Li_x molecular chains through the ion-dipole interaction.As such,the PAA-Li_(0.25)/SiO electrode exhibits exceptional mechanical properties and the lowest volume change,as well as the optimum cycling(1237.3 mA h g^(-1)after 100cycles at 0.1 C)and rate performance(1000.6 mA h g^(-1)at 1 C),significantly outperforming the electrode using pristine PAA binder.This work paves the way for quantitative regulation of binders at the molecular level.

Effects of Different Line Spacing and Seedling Belt Width on Yield Formation of Broad-Width Fine Sowing Wheat

In order to explore the interaction effects of line spacing and seedling belt width on wheat yield formation and improve the cultivation techniques of broadwidth and fine seeding of wheat,a high-yielding winter wheat cultivar Shannong 28 was selected as material. Using the split plot design,the main plot was set with line spacing as 20,25 and 30 cm,respectively,and the sub-plot was set with seedling belt width as 3,5,7,9 and 11 cm,respectively. Then,the population dynamics,dry matter accumulation and translocation and yield of wheat were studied under the experimental conditions. The results showed that under the line spacing of 20 cm,the dry matter accumulation and yield of winter wheat were higher with the seedling belt width of 5 cm. When the line spacing was 25 cm,the dry matter accumulation and yield under the seedling belt width of 9 cm reached a high level. Under the line spacing of 30 cm,Shannong 28 achieved higher dry matter accumulation and yield with the seedling belt width of 11 cm. Comprehensive analysis revealed that the suitable treatment for Shannong 28 was 25 cm of line spacing with 9 cm of seedling belt width,which could realize the coordination of the three factors of yield composition and get higher yield. Therefore,the reasonable line spacing and seedling belt width were the important technical ways to realize high yield of wheat.

Clinical outcomes of newly diagnosed primary central nervous system lymphoma treated with zanubrutinib-based combination therapy

BACKGROUND High-dose methotrexate(HD-MTX)combined with other chemotherapeutic agents is an effective treatment for patients with newly diagnosed primary central nervous system lymphoma(PCNSL);however,some patients have adverse reactions.AIM To retrospectively evaluate disease outcomes and mutational profiles in newly diagnosed PCNSL patients treated with a zanubrutinib/HD-MTX combination regimen.METHODS Nineteen newly diagnosed PCNSL patients were treated with zanubrutinib/HDMTX until disease progression,intolerable toxicities,or physician/patientdirected withdrawal.Safety and efficacy were assessed per the CTCAE v5.0 and RECIST v1.1 criteria,respectively.The primary endpoint was the objective response rate(ORR),and the secondary endpoints were progression-free survival,overall survival(OS),and safety.RESULTS The median follow-up duration was 14.7 mo(range,3.9–30 mo).The ORR for all patients was 84.2%,and 2-year progression-free-and OS rates were 75.6%and 94.1%,respectively.All patients completed the induction phase,and nine patients underwent autologous stem cell transplantation as consolidation therapy,resulting in an ORR of 88.9%.Ten patients received zanubrutinib as maintenance therapy and achieved an ORR of 80%.All patients showed an acceptable safety profile.The sequencing results for cerebrospinal fluid(CSF)and tumor tissue showed that PIM1 mutations were the most frequent genetic alterations.Circulating tumor DNA was correlated with disease relapse and response.CONCLUSION Our empirical observations demonstrated that the combination of zanubrutinib with HD-MTX yielded a marked clinical response and tolerability among newly diagnosed PCNSL patients.Non-invasive CSF liquid biopsy profiling may be feasible for evaluating treatment response and tumor burden.

LITAF Promotes Atherosclerotic Plaque Formation by Stimulating the NF-κB Inflammatory Pathway

Objective Lipopolysaccharide-induced tumor necrosis factor-αfactor(LITAF)protein is a newly discovered inflammatory protein.This study aims to study the role of LITAF in the formation of atherosclerosis.Methods A total of 10 C57BL/6J mice and 10 C57BL/6J mice with knockout of LITAF gene(C57BL/6J–LITAF–)were divided into two groups:the control group and the LITAF^(−/−)group.The animals were accommodated for 16 weeks and then euthanized with their hearts and aortas isolated thereafter.Next,the roots of the mouse aorta were cryosectioned and stained with Oil Red O staining and immunohistochemical staining(CD68,α-SMA,and Masson),respectively.The area of Oil Red O staining and the proportion of positive expression after immunohistochemical staining were then compared between the control and LITAF^(−/−)groups.At the same time,the blood of mice was collected for the extraction of proteins and RNA.The proteins and RNA were used to detect the expression of major molecules of the NF-κB inflammatory pathway in mice in the control group and the LITAF^(−/−)group by Western blotting and RT-PCR.Results Oil Red O staining of the aortic root sections of the mice in each group revealed that the area of atherosclerotic plaques in the LITAF^(−/−)group was substantially lower than that in the control group(P<0.05).Moreover,immunohistochemical staining determined that the expression level ofα-SMA and CD68 in the LITAF^(−/−)group was significantly lower than that in the control group,whereas the results were reversed following Masson staining(P<0.05).The expression levels of P65 and caspase 3 were significantly lower in the LITAF^(−/−)group than in the control group(P<0.05),whereas the expression level of IκB was higher in the LITAF^(−/−)group.Conclusion LITAF might participate in the formation of atherosclerotic plaque through the NF-κB pathway and play a promoting role in the formation of atherosclerosis.

Identification of a natural PLA2 inhibitor from the marine fungus Aspergillus sp.c1 for MAFLD treatment that suppressed lipotoxicity by inhibiting the IRE-1a/XBP-1s axis and JNK signaling

Lipotoxicity is a pivotal factor that initiates and exacerbates liver injury and is involved in the development of metabolic-associated fatty liver disease(MAFLD).However,there are few reported lipotoxicity inhibitors.Here,we identified a natural anti-lipotoxicity candidate,HN-001,from the marine fungus Aspergillus sp.C1.HN-001 dose-and time-dependently reversed palmitic acid(PA)-induced hepatocyte death.This protection was associated with IRE-1a-mediated XBP-1 splicing inhibition,which resulted in suppression of XBP-1s nuclear translocation and transcriptional regulation.Knockdown of XBP-1s attenuated lipotoxicity,but no additional ameliorative effect of HN-001 on lipotoxicity was observed in XBP-1s knockdown hepatocytes.Notably,the ER stress and lipotoxicity amelioration was associated with PLA2.Both HN-001 and the PLA2 inhibitor MAFP inhibited PLA2 activity,reduced lysophosphatidylcholine(LPC)level,subsequently ameliorated lipotoxicity.In contrast,overexpression of PLA2 caused exacerbation of lipotoxicity and weakened the anti-lipotoxic effects of HN-001.Additionally,HN-001 treatment suppressed the downstream pro-apoptotic JNK pathway.In vivo,chronic administration of HN-001(i.p.)in mice alleviated all manifestations of MAFLD,including hepatic steatosis,liver injury,inflammation,and fibrogenesis.These effects were correlated with PLA2/IRE-1a/XBP-1s axis and JNK signaling suppression.These data indicate that HN-001 has therapeutic potential for MAFLD because it suppresses lipotoxicity,and provide a natural structural basis for developing anti-MAFLD candidates.

Narciclasine induces colon carcinoma cell apoptosis by inhibiting the IL-17A/Act1/TRAF6/NF-kB signaling pathway

IL-17 A is a promoter of colorectal cancer initiation and progression.Narciclasine is a polyhydroxy alkaloid compound isolated from Narcissus plants,which has potent anti-inflammatory and antitumor actions.The effects of narciclasine on colorectal tumors were evaluated,with a focus on IL-17 A.Narciclasine reduced the growth of HCT-116 and SW-480 colon cancer cells in vitro and in vivo in murine xenografts.The results of flow cytometry on JC-1 and Annexin V/PI revealed that narciclasine significantly reduced the mitochondrial membrane potential and induced apoptosis,findings confirmed by western blotting results of reduced Bcl2 and enhanced Bax expression,as well as accumulation of cleaved Caspase-3,Caspase-8,Caspase-9,and cytoplasmic Cytochrome-c.After narciclasine incubation,IL-17 A,Act1,and TRAF6 were down-regulated,while p-P65(Ser536)accumulated in the cytoplasm,a finding confirmed by laser scanning confocal microscopy.IL17A substitution could partly reverse these narciclasine effects while they were elevated by IL17A silencing.Moreover,IL-17 A,Act1,and TRAF6 were significantly expressed to greater extents in human colorectal cancer compared to normal adjacent tissue specimens and were closely linked with a poor prognosis.This study provided evidence that narciclasine may be a useful therapeutic drug for colorectal cancer treatment through its actions in down-regulating the L-17A/Act1/TRAF6/NF-kB anti-apoptotic signaling pathway.

Multiple lentigines syndrome with positive family history:a case report and review of the literature

Multiple lentigines syndrome is an autosomal dominant genetic disease,and its expressivity and penetrance are variable.It is also known as LEOPARD syndrome(LS).The genes known to be associated with LS include PTPN11,RAF1 and BRAF.The diagnosis of LS(OMIM 151100)is based on the observation of key features in the clinical background.LS caused by a germline PTPN11 mutation are characterized as multisystemic anomalies and variable marked phenotypes such as multiple lentigines and cafénoir spots,electrocardiographic conduction abnormalities,ocular hypertelorism/obstructive cardiomyopathy,pulmonary stenosis,abnormal genitalia,retardation of growth,and deafness.Phenotype overlap complicates clinical discrimination within RASopathies,making the diagnosis of LS more confusing and challenging.Besides,LS patients do not usually present with all these typical clinical features,increasing the possibility of underdiagnosis or misdiagnosis.Herein,we report a case of a 41-year-old male presenting with multiple dark pigmented macules all over the body,thoracic deformity and family history.And we followed up the patients.

年龄相关性黄斑变性(ARMD)是中老年人不可逆性视力损害的一种主要原因,严重影响个人生活质量并加重社会卫生经济负担。晚期ARMD在临床上有两种表现类型,即干性ARMD(dARMD)和湿性ARMD(nARMD)。nARMD以抗血管内皮生长因子作为一线药物已取得显著疗效,而dARMD尚无确切的治疗方法。本文就dARMD在临床试验中取得显著进展、可望上市的潜在药物、生物疗法和中医中药进行综述,包括抗炎药(强力霉素和FHTR2163)、抗氧化药(利舒尼布和依来米普瑞肽)、补体抑制剂(APL-2和滋目若)、视觉周期调节剂(ALK-001)、神经保护剂(溴莫尼定)、干细胞移植(MA09-hRPE和BMMF)、基因疗法(HMR59)和中医中药(藏红花、姜黄素、槲皮素和白藜芦醇)等。这些药物临床试验疗效显著,应用前景广阔,为ARMD改善与治疗带来巨大希望。

富锂锰基层状正极材料的合成及其首周过充下的结构演化

富锂锰基层状正极材料由于具有较低的成本和超过250 mAh·g^(-1)的放电比容量,成为很有前景的正极材料之一,但是其本身存在的首周库仑效率低和电压衰减等问题限制了产业化进程。高充电电压会导致富锂材料结构不稳定从而增加电池的安全隐患,因此在较高的充电电压下,材料的首周充放电结构演化有待进一步研究。本文首先通过碳酸盐共沉淀法合成前驱体,经过混锂后煅烧制备富锂锰基层状正极材料(Li_(1.13)Ni_(0.18)Co_(0.09)Mn_(0.56O2)),并研究不同充电截止电压对其首周库仑效率和循环性能的影响。研究表明,高充电电压会带来容量增加,但其首周库仑效率将大幅降低。循环伏安表征发现,充电截止电压为5.0 V时,部分体相的晶格氧会发生可逆的氧化反应,这将有利于容量的提升。TEM、XRD和SEM表征结果显示,在首周充电后电极材料不仅发生了深入到体相的结构变化,同时出现了大片的层错和尖晶石相MnO_(x)和NiO_(x)等不可逆相变,还会与电解液发生反应,材料结构无法保持稳定。结合Mapping和XPS表征结果显示,充电电压较高时会有更多的体相晶格氧参与氧化还原反应,这将使更多具有强氧化性的过氧和超氧离子与电解液发生副反应,并伴随过渡金属的溶出,加速材料的结构坍塌,最终不利于电池的长循环性能。

Bio-Derived Hierarchical Multicore–Shell Fe2N-Nanoparticle-Impregnated N-Doped Carbon Nanofiber Bundles:A Host Material for Lithium-/Potassium-Ion Storage

Despite the significant progress in the fabrication of advanced electrode materials,complex control strategies and tedious processing are often involved for most targeted materials to tailor their compositions,morphologies,and chemistries.Inspired by the unique geometric structures of natural biomacromolecules together with their high affinities for metal species,we propose the use of skin collagen fibers for the template crafting of a novel multicore-shell Fe2N-carbon framework anode configuration,composed of hierarchical N-doped carbon nanofiber bundles firmly embedded with Fe2N nanoparticles(Fe2N@N-CFBs).In the resultant heterostructure,the Fe2N nanoparticles firmly confined inside the carbon shells are spatially isolated but electronically well connected by the long-range carbon nanofiber framework.This not only provides direct and continuous conductive pathways to facilitate electron/ion transport,but also helps cushion the volume expansion of the encapsulated Fe2N to preserve the electrode microstructure.Considering its unique structural characteristics,Fe2N@N-CFBs as an advanced anode material exhibits remarkable electrochemical performances for lithium-and potassium-ion batteries.Moreover,this bio-derived structural strategy can pave the way for novel low-cost and high-efficiency syntheses of metal-nitride/carbon nanofiber heterostructures for potential applications in energy-related fields and beyond.

Migration and distribution of saline ions in bauxite residue during water leaching

Bauxite residue,a highly saline solid waste produced from digestion of bauxite for alumina production,is hazardous to the environment and restricts vegetation establishment in bauxite residue disposal areas.A novel water leaching process proposed here was used to investigate the dynamic migration and vertical distribution of saline ions in bauxite residue.The results show that water leaching significantly reduced the salinity of bauxite residue,leaching both saline cations Na+,K+,Ca2+and anions CO32-,SO42-,HCO3-.Na+and K+migrated from 40-50 to 20-30 cm of the column,presenting a high migration capacity.The migration capacity of Ca2+was lower and accumulated at 30-40 cm of the column.CO32-initially distributed at 20-30 cm of the column,subsequently transported to 30-40 cm of the column,and finally returned to 20-30 cm of the column along with evaporation.SO42-was originally distributed at 40-50 cm,but finally migrated to 20-30 cm of the column.Nevertheless,HCO3-remained at the bottom of the column,and its migratory was less affected by evaporation.
