Inflammatory diseases (IDs) are a general term of diseases characterized by chronic inflammation as the primary pathogenetic mechanism, which seriously affect the quality of patient′s life and cause significant social and medical burden. Current drugs for IDs include nonsteroidal anti-inflammatory drugs, corticosteroids, immunomodulators, biologics, and antioxidants, but these drugs may cause gastrointestinal side effects, induce or worsen infections, and cause non-response or intolerance. Given the outstanding performance of metal polyphenol network (MPN) in the fields of drug delivery, biomedical imaging, and catalytic therapy, its application in the diagnosis and treatment of IDs has attracted much attention and significant progress has been made. In this paper, we first provide an overview of the types of IDs and their generating mechanisms, then sort out and summarize the different forms of MPN in recent years, and finally discuss in detail the characteristics of MPN and their latest research progress in the diagnosis and treatment of IDs. This research may provide useful references for scientific research and clinical practice in the related fields.

Platycodonis Radix is the dry root of Platycodon grandiflorum of Campanulaceae, which has a variety of pharmacological effects and is a commonly used bulk Chinese medicine. In this study, the chloroplast genome sequences of six P. grandiflorum from different producing areas has been sequenced with Illumina HiSeq X Ten platform. The specific DNA barcodes were screened, and the germplasm resources and genetic diversity were analyzed according to the specific barcodes. The total length of the chloroplast genome of 6 P. grandiflorum samples was 172 260-172 275 bp, and all chloroplast genomes showed a typical circular tetrad structure and encoded 141 genes. The comparative genomics analysis and results of amplification efficiency demonstrated that trnG-UCC and ndhG_ndhF were the potential specific DNA barcodes for identification the germplasm resources of P. grandiflorum. A total of 305 P. grandiflorum samples were collected from 15 production areas in 9 provinces, for which the fragments of trnG-UCC and ndhG_ndhF were amplificated and the sequences were analyzed. The results showed that trnG-UCC and ndhG_ndhF have 5 and 11 mutation sites, respectively, and 5 and 7 haplotypes were identified, respectively. The combined analysis of the two sequences formed 13 haplotypes (named Hap1-Hap13), and Hap4 is the main genotype, followed by Hap1. The unique haplotypes possessed by the three producing areas can be used as DNA molecular tags in this area to distinguish from the germplasm resources of P. grandiflorum from other areas. The haplotype diversity, nucleotide diversity and genetic distance were 0.94, 4.79×10^-3 and 0.000 0-0.020 3, respectively, suggesting that the genetic diversity was abundant and intraspecific kinship was relatively close. This study laid a foundation for the identification of P. grandiflorum, the protection and utilization of germplasm resources, and molecular breeding.

italic>Acanthopanax senticosus is one of the genuine regional herb in Northeast China. In this study, we identified the germplasm resources of commercial A. senticosus samples based on atpI and atpB_rbcL according to the previous chloroplast genome sequencing results, and determinated the content of syringin by HPLC to evaluated the quality of commercial samples. A total of 80 A. senticosus samples were collected from 47 cities in 24 provinces. DNA was extracted to amplify the products of atpI and atpB_rbcL by PCR. The results showed that 7 haplotypes (H2, H5, H8, H10, H12, H14, H23) were formed by the combined analysis of the two gene fragments. H2 from Yichun in Heilongjiang, Shangzhi in Harbin, Suihua in Heilongjiang, Fushun in Liaoning, Benxi in Liaoning, Changbai in Jilin and Jingyu in Jilin were the dominant genotype, representing 58.75% of the total samples. H14 and H23 were the unique haplotypes of the producing area. It is speculated that the commercial A. senticosus samples with haplotypes of H14 and H23 are from Raohe, Shuangyashan, Heilongjiang and Mingshui, Suihua, Heilongjiang, respectively. HPLC analysis indicated that the content of syringin in 73.96% of the samples met the Pharmacopoeia standards. There was a significant difference in the content of syringin among the samples, ranging from 0.003 7% to 0.524 5%, with a difference of 0.520 8%, indicating that the quality of the samples in the market of A. senticosus was uneven. However, there were no significant differences in the contents of syringin in the commercial A. senticosus among different haplotypes. The content of syringin in the haplotype H23 in the market sample is relatively high, so it may be a germplasm with better quality. This study researched the germplasm resources and medicinal materials quality of commercial A. senticosus samples and will help guide the commercial circulation, reasonable medication of A. senticosus, and the screening of excellent germplasm.

Epilepsy is a chronic disease characterized by recurrent,sudden,and excessive synchronous discharge of neurons in the brain,leading to transient brain dysfunction,and inflammatory responses in specific regions within the central nervous system are common features of epilepsy.In recent years,there has been increasing evidence that endoplasmic reticulum stress is involved in the pathology of epilepsy,which activates the unfolded protein response,then regulate and control nuclear factor kappa-B(NF-κB),efficiently induces glial cell activation through the release of pro-inflammatory signals,in turn affects epileptogenesis and seizures by triggering neuroinflammation.This review focuses on the close link between endoplasmic reticulum stress and glial cell activation-mediated neuroinflammation in epilepsy pathology,aiming to provide insights for a deeper understanding of epilepsy.

Aim To investigate the enhanced efficacy and reduced toxicity of GanoExtra in combination with cyclophosphamide(CTX)on inhibiting lung metastasis and immune function in mice.Methods The CCK-8 method was used to verify the cytotoxic effects of Gano-Extra on MCF-7 and 4T1 tumor cells.In vivo experi-ment,a mouse model of lung metastasis of breast canc-er was established by injecting 4T1 tumor cells into the tail vein,which was divided into four groups including 4T1 model group,CTX group,GanoExtra group and GanoExtra+CTX group.The control group was set.After 21 days,the mice were euthanized under anes-thesia,and the body weight of the mice was recorded.Average lung index and spleen index were calculated.The mouse spleen lymphocyte transformation experi-ment was used to determine the activity of spleen cells.The NK cell activity assay was used to determine the activity of NK cells.Blood cells were determined in mouse blood samples.Flow cytometry was used to de-termine the levels of CD4+and CD8+T cells in blood samples.ELISA was used to measure the levels of TNF-α and IL-6 in serum.HE staining was used to ob-serve the pathological morphological changes in tumors and various tissues;and CFSE staining was used to de-termine the proliferative effect of GanoExtra on CD8+cells.Results In vitro GanoExtra at 50 mg·L-1 sig-nificantly inhibited the activity of MCF-7 and 4T1 tumor cells.In the breast cancer pulmonary metastasis model,compared with the model group,the spleen in-dex and blood WBCs content were significantly re-duced,while the activity of NK cells,spleen cells,and the proportion of RBCs,CD 3+and CD 8+T cells in the blood were significantly increased.At the end of the treatment,compared with the CTX group,the number of lung metastases and lung index of the Gano-Extra+CTX group were significantly reduced,and the levels of HGB,CD8+cells,IL-6,and TNF-α in the blood of mice were significantly increased.GanoExtra at 10 mg·L-1 significantly promoted the proliferation of CD8+T cells in vitro.Conclusions GanoExtra can enhance the inhibitory effect of CTX on tumor metasta-sis,alleviate adverse reactions such as splenomegaly and pulmonary enlargement caused by CTX,and have a health-promoting function of promoting the prolifera-tion of CD8+T cells to enhance the immune efficacy of the body.

Objective To investigate the high-frequency ultrasonic anatomical features of the adjacent C7 transverse process and its clinical value in stellate ganglion block(SGB).Methods High-frequency ultrasound was applied to obtain ultrasonographic anatomical sonogram features in the plane of bilateral C7 transverse processes in 52 cases(104 sides in total)of healthy adults and then stored for the operator to learn and correctly label each tissue structure.Fifty patients who underwent ultrasound-guided SGB were selected and divided into the BC7 group(25 cases before study)and AC7 group(25 cases after study).The operation time,SGB success rate,number of adjusted needle tips,dosage of anaesthetic and adverse reaction of patients in both group were recorded.Results The main muscles observed in the C7 plane were the longissimus and anterior scalene muscles,the ultrasonographic anatomical relationships of the vagus nerve located in the carotid sheath,the pleura located posterior to the subclavian artery,and the recurrent laryngeal nerve located in the vicinity of the branches of the inferior thyroid artery are described,and the stellate ganglion was illustrated as a flattened hypoechogenic structure visible on the deep surface of the prevertebral fascia in the region of the external cervical longissimus muscle,vertebral artery and vein,and the medial aspect of the anterior oblique muscle,and emanated the sonographic features of several hypoechoic nerve bundles.Ultrasound guided SGB was completed uneventfully in patients of both groups,and all patients developed Horner syndrome,with the SGB success rate of 100%.The operation time[(5.36±1.11)minutes]of patients in the BC7 group was longer than that in the AC7 group[(3.08±0.86)minutes],the number of adjusted needle tips[(4.20±1.00)times]of patients in the BC7 group was more than that in the AC7 group[(2.24±0.87)times],and the dosage of anaesthetic[(1.82±0.28)mL]of patients in the BC7 group was more than that in the AC7 group[(1.64±0.22)mL],all the differences were statistically significant(P<0.05).There was no significant difference in the incidence of adverse reaction between the two groups(P>0.05).Conclusion After ultrasonic learning of adjacent structures through C7 transverse process,SGB is safe and easy to perform.

Brucellosis,a worldwide epidemic bacterial zoonotic infectious disease caused by bacteria of the genus Brucella,jeopardizes livestock production and poses a major threat to public health safety.Among the various components of Brucella,the outer membrane proteins play crucial roles as the primary immune and protective antigens.These proteins are closely asso-ciated with Brucella's virulence,regulation of the immune response,and ability to survive and multiply within host cells.This article summarizes recent research progress in the primary outer membrane proteins of Brucella,and offers a synthesized view of the current knowledge landscape.Understanding the antigenic characteristics of Brucella outer membrane proteins may sub-stantially contribute to the establishment of new diagnostic methods and the design of new vaccines,thus potentially leading to more effective prevention strategies against brucellosis.The review provides a reference for future studies and may aid in brucel-losis control efforts.

Objective:To investigate the molecular mechanism of proteolytic cleavage of unusually large von Willebrand Factor(ULVWF)on endothelial cells by ADAMTS13(a disintegrin and metalloprotease with thrombospondin type 1 repeats-13)in the absence of fluid shear stress,so as to provide a theoretical basis for the pathogenesis of thrombotic thrombocytopenic purpura(TTP)and other thrombotic disorders.Methods:The ADAMTS13-mediated proteolysis of ULVWF on the surface of endothelial cells in the absence of fluid shear stress was observed through immunofluorescence microscopy.The variation in VWF antigen levels in the conditioned media were determined by ELISA assay.The levels of VWF and the proteolytic fragments released into the conditioned media were determined by ELISA assay and Western blot in the absence and presence of fluid shear stress or FⅧ.The effect of ADAMTS13-mediated ULVWF cleavage on the normal distribution of plasma VWF multimers was evaluated by multimer analysis.Histamine stimulated human umbilical vein endothelial cells(HUVECs)were incubated with ADAMTS13 and various N-and C-terminally truncated mutants.Then the ULVWF that maintained binding to the cells were observed through immunofluorescence microscopy and the soluble ULVWF released from endothelial cells was determined by ELISA,so as to demonstrate the domains of ADAMTS13 required for proteolysis of ULVWF on endothelial cells.Results:The ULVWF strings on the endothelial cell surface were rapidly proteolyzed by recombinant and plasma ADAMTS13 in the absence of fluid shear stress.This proteolytic processing of ULVWF depended on incubation time and AD AMTS 13 concentration,but not shear stress and FⅧ.The distribution of VWF releaseded by ADAMTS13-mediated proteolysis was quite similar to that secreted by endothelial cells under histamine stimulation,suggesting the ULVWF cleavage occured at the cell surface.The proteolysis of the ULVWF on endothelial cells required the Cys-rich(CysR)and spacer domains,but not the TSP1 2-8 and CUB domains of ADAMTS13.Conclusion:The ULVWF polymers on endothelial cells are sensitive to ADAMTS13-mediated cleavage even in the absence of fluid shear stress.The findings provide novel insight into the molecular mechanism of ADAMTS13-mediated ULVWF cleavage at the cellular level and may contribute to understanding of the pathogenesis of TTP and other thrombotic disorders.

Objective To explore the biomarkers and potential mechanisms of chronic restraint stress-induced myocardial injury in hyperlipidemia ApoE-/-mice.Methods The hyperlipidemia combined with the chronic stress model was established by restraining the ApoE-/-mice.Proteomics and bioinformatics techniques were used to describe the characteristic molecular changes and related regulatory mechanisms of chronic stress-induced myocardial injury in hyperlipidemia mice and to explore potential diagnostic biomarkers.Results Proteomic analysis showed that there were 43 significantly up-regulated and 58 sig-nificantly down-regulated differentially expressed proteins in hyperlipidemia combined with the restraint stress group compared with the hyperlipidemia group.Among them,GBP2,TAOK3,TFR1 and UCP1 were biomarkers with great diagnostic potential.KEGG pathway enrichment analysis indicated that fer-roptosis was a significant pathway that accelerated the myocardial injury in hyperlipidemia combined with restraint stress-induced model.The mmu_circ_0001567/miR-7a/Tfr-1 and mmu_circ_0001042/miR-7a/Tfr-1 might be important circRNA-miRNA-mRNA regulatory networks related to ferroptosis in this model.Conclusion Chronic restraint stress may aggravate myocardial injury in hyperlipidemia mice via ferrop-tosis.Four potential biomarkers are selected for myocardial injury diagnosis,providing a new direction for sudden cardiac death(SCD)caused by hyperlipidemia combined with the restraint stress.
