Authorship is one of the important issues in academic publishing ethics.Standardized authorship is not only an important manifestation of research integrity but also a reflection of the academic credibility of journals.Currently,misconduct in authorship of medical papers occurs frequently.This paper systematically explores the problems in authorship of medical papers,and based on the standards formulated by the Inter-national Committee of Medical Journal Editors(ICMJE)and the Committee on Publication Ethics(COPE),deeply analyzes the core elements of defining authorship qualifications and dividing responsibilities.Com-bined with typical cases in the editorial practice of Cancer Biology & Medicine,it dissects the root causes of authorship misconduct and proposes comprehensive solutions,including requiring authors to strictly abide by authorship standards,strengthening the journal's review mechanism for authorship,adopting contributor roles taxonomy(CRediT),and enhancing research integrity education in research institutions,so as to pro-vide reference for preventing academic misconduct.

BACKGROUND:Our previous study found that Modified Erxian Pill could alleviate inflammation in collagen-induced arthritis rats,but its mechanism needs to be further verified. OBJECTIVE:To analyze the components absorbed in the blood of Modified Erxian Pill,and observe the effect of the drug-containing serum of Modified Erxian Pill on pyroptosis of J774A.1 macrophages. METHODS:(1)Analysis of components absorbed in the blood of Modified Erxian Pill:Ultra-high performance liquid chromatography-high resolution mass spectrometry was used to detect and identify Modified Erxian Pill and its components absorbed in the blood.(2)Effect of the drug-containing serum of Modified Erxian Pill on pyroptosis of J774A.1 macrophages:Molecular docking technology was used to initially verify the sesquiterpenoids and NLRP3 in components absorbed in the blood of Modified Erxian Pill.J774A.1 macrophages were randomly divided into blank control group,lipopolysaccharide+adenosine triphosphate group,and lipopolysaccharide+adenosine triphosphate+Modified Erxian Pill with low(2.5%),medium(5%),and high(10%)dose groups.The release of lactate dehydrogenase in the cell supernatant of each group was detected according to the kit instructions.The levels of interleukin-1β and interleukin-18 in cell supernatant were detected in each group by ELISA.The cell membrane damage was detected by Hoechst/PI staining.The expression levels of NLRP3,Caspase-1,GSDMD,and GSDMD-N protein in the cells of each group were detected by western blot assay. RESULTS AND CONCLUSION:(1)A total of 32 active components of Modified Erxian Pill were identified,and 21 components entered the blood.The main components into blood included a variety of sesquiterpenoids.(2)Molecular docking results showed that 3-O-Acetyl-13-deoxyphomenone,Incensol oxide,Atractylenolide III,Rupestonic acid,and 3,7-Dihydroxy-9,11-eremophiladien-8-one had good binding activity with NLRP3.(3)Compared with the blank control group,lactate dehydrogenase activity and the expression levels of interleukin-1β and interleukin-18 were significantly increased in cell supernatant of lipopolysaccharide+adenosine triphosphate group(P<0.001).Hoechst/PI staining showed that the number of PI-positive cells was significantly increased.After the intervention of lipopolysaccharide+adenosine triphosphate+Modified Erxian Pill group,all of them showed different degrees of reduction.(4)Compared with the blank control group,NLRP3,Caspase-1,GSDMD,and GSDMD-N protein expression levels were significantly increased in the lipopolysaccharide+adenosine triphosphate group(P<0.05).Compared with lipopolysaccharide+adenosine triphosphate group,the protein expressions of NLRP3,Caspase-1,GSDMD,and GSDMD-N were significantly decreased in the lipopolysaccharide+adenosine triphosphate+Modified Erxian Pill group(P<0.05),and had a certain dose dependence.These findings verify that the drug-containing serum of Modified Erxian Pill may inhibit the pyroptosis of J774A.1 macrophages by regulating the NLRP3/Caspase-1/GSDMD pathway.

BACKGROUND:Rheumatoid arthritis is an inflammatory disease.Many studies have shown that wogonin has a good anti-inflammatory effect on rheumatoid arthritis,but its exact efficacy and specific mechanism of action remain to be clarified. OBJECTIVE:To investigate the mechanism of wogonin ameliorating joint inflammation by regulating endoplasmic reticulum stress pathway in rats with collagen-induced arthritis. METHODS:(1)At the animal level:Female Wistar rats were divided into healthy control group,arthritis model group and wogonin treatment group.Rat models of arthritis in the latter two groups were established by subcutaneous injection of bovine type Ⅱ collagen and adjuvant.In the wogonin group,wogonin was given by gavage for 28 consecutive days after modeling.During this period,the rats in each group were weighed,and arthritis score and ankle swelling were measured every 7 days.After the experiment,the pathological changes of the joint were observed,the mRNA and protein levels of endoplasmic reticulum stress pathway GRP78 and CHOP were detected by qRT-PCR,western blot,and immunohistochemistry.(2)At the cellular level,cell counting kit-8 was used to detect the cytotoxic effect of wogonin on fibroblast-like synoviocytes from rats with collagen-induced arthritis.The fibroblast-like synoviocytes induced by thapsigargin were treated with different concentrations of wogonin.The levels of interleukin-1β and tumor necrosis factor-α in the cell supernatant were detected by ELISA,and the intracellular reactive oxygen species in each group were determined by DCFH-DA probe method.The mRNA and protein levels of GRP78,IRE1α,XBP1s and CHOP were detected by qRT-PCR and western blot,respectively. RESULTS AND CONCLUSION:Compared with the healthy control group,arthritis index score and ankle swelling degree in the arthritis model group were increased(P<0.01),synovial hyperplasia,inflammatory cell infiltration,cartilage destruction and bone erosion were observed in pathological sections,and the mRNA and protein expressions of GRP78 and CHOP in the ankle were significantly increased(P<0.01),which were mainly located in synovial tissue and articular surface.Compared with the arthritis model group,the arthritis index score and ankle swelling degree in the wogonin treatment group were decreased(P<0.05),synovial hyperplasia and the number of inflammatory cells were decreased,cartilage destruction and bone erosion were alleviated,the mRNA and protein expression levels of GRP78 and CHOP in the ankle were decreased(P<0.05),particularly in synovial tissue and on the articular surface.There was no significant difference in body mass among the three groups(P>0.05).In the cell experiment,200 μmol/L wogonin significantly reduced the survival rate of fibroblast-like synoviocytes(P<0.01).Compared with the blank control group,the levels of interleukin-1β,tumor necrosis factor-α,content of reactive oxygen species,and mRNA and protein expression of GRP78,IRE1α,XBP1s,and CHOP in the thapsigargin group were significantly increased(P<0.05);compared with the thapsigargin group,50 and 100 μmol/L wogonin significantly reduced the levels of interleukin-1β and tumor necrosis factor-α in the cell supernatant(P<0.05,P<0.01),and 100 μmol/L wogonin significantly reduced the content of reactive oxygen species(P<0.01)and down-regulated the mRNA and protein expression levels of GRP78,IRE1α,XBP1s and CHOP(all P<0.05).These results suggest that wogonin can effectively alleviate joint inflammatory responses in rats with collagen-induced arthritis,and the endoplasmic reticulum stress pathway may be the key target of its intervention.

Objective:To assess the optimal timing and short-term clinical efficacy of sinus drug-eluting stent placement in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).Methods:The minimum sample size was calculated using G-power 3.1.9.7 software. From March 2021 and May 2023, a total of 114 eligible patients with CRSwNP were recruited in this study at the Department of Otolaryngology Head and Neck Surgery, Renmin Hospital of Wuhan University. The patients were randomly assigned to three groups: the control group, the intraoperative stent group, and the postoperative stent group. In the intraoperative stent group, drug-eluting stents were implanted during endoscopic sinus surgery (ESS), while patients in the postoperative stent group received drug-eluting stent 2 weeks after ESS, following routine debridement of the surgical cavity. Bilateral ethmoid sinus stenting was performed for both stent groups, while the control group only underwent ESS with standard postoperative cavity debridement. All subjects were followed up at 2, 4, 8, and 12 weeks postoperatively. Nasal symptom Visual Analog Scale (VAS) scores and endoscopic evaluations of the ethmoid cavity-assessing obstruction, crusting, polypoid mucosal changes, epithelialization of ethmoid cavity, need for intervention, and complications such as middle turbinate lateralization and adhesions-were collected to evaluate the treatment efficacy of three groups. Statistical analyses were performed using GraphPad Prism 9. Analysis of variance (ANOVA) was applied to analyze continuous variables among the three groups, and chi-square tests were used for categorical variables.Results:Among 114 CRSwNP patients, 21 lost follow-up patients and 7 postoperative oral corticosteroid intervention patients were excluded. Finally, 86 patients were included in the analysis, including 45 males and 41 females, aged 18-65 years. The cohort comprised 29 in the control group, 29 in the intraoperative stent group, and 28 in the postoperative stent group. Successful bilateral ethmoid sinus stent implantation was achieved in both stent groups. At 4 weeks postoperatively, compared with the control group, both stent groups showed significant improvements in nasal congestion and rhinorrhea scores ( P<0.05). At 8 weeks, the postoperative group continued to demonstrate superior outcomes in these two symptoms (both P<0.05), while the intraoperative group only showed significant improvement in nasal congestion ( P<0.05). No significant differences were observed in facial pressure, olfactory loss, or nasal dryness scores among the three groups (all P>0.05). Endoscopic evaluation revealed that both stent groups had significant improvements in ethmoid sinus obstruction scores at 4 weeks compared with the control group, with the postoperative group maintaining this advantage at 8 weeks ( P<0.05). At 2 weeks, the intraoperative stent group had higher crusting scores than other groups ( P<0.05). At 2 weeks after stent implantation, the postoperative stent group had significantly lower crusting scores than the intraoperative stent group ( P<0.001). The intraoperative group had a significantly lower incidence of ethmoid sinus edema and polypoid changes at 4 weeks compared with the control group ( P<0.05), while the postoperative group showed reduced rates of these pathological changes at 4, 8, and 12 weeks (all P<0.05). The postoperative stent group had significantly higher rates of ethmoid sinus mucosal epithelialization at 8 and 12 weeks postoperatively compared with the control group. The intraoperative stent group required fewer interventions than the control group at both 8 and 12 weeks, while the postoperative stent group maintained lower interventions rates at all follow-up points after implantation (all P<0.05). Additionally, the incidence of complications was significantly lower in both stent groups compared with the control group ( P<0.05). Overall, stent implantation at different time points showed similar efficacy, with the postoperative group demonstrating more stable outcomes and less crusting/coagulation formation compared with the intraoperative group. Conclusions:The implantation of corticosteroid sinus stents in the ethmoid sinuses effectively controls postoperative inflammation, promotes mucosal epithelialization, and reduces postoperative intervention rates. Stent implantation two weeks after surgery is feasible. Adjusting the timing of stent placement can minimize crust formation and maximize the corticosteroid effect, thereby facilitating a benign course of the surgical site.

BACKGROUND:Acute liver injury can result from a variety of causes,and if not treated in time,it will develop into acute liver failure and seriously affect the life safety of patients.As the liver is the largest immune organ and metabolic organ,there is no optimal treatment for acute liver injury.The adipose tissue-derived mesenchymal stem cell has multi-differentiation potential and immunomodulatory activity,so it has been gradually becoming an effective tool for the treatment of acute liver injury.OBJECTIVE:To review the progress and molecular mechanism of adipose tissue-derived mesenchymal stem cell and its modification in different ways in the treatment of acute liver injury.METHODS:Relevant articles published from 2000 to 2023 were retrieved from PubMed,Web of Science,and CNKI databases.English search terms were"acute liver injury,liver injury,adipose tissue-derived mesenchymal stem cell,liver injury repair,stem cell transplantation,stem cell repair,cell surface engineering,stem cell modification."Chinese search terms were"acute liver injury,liver injury,adipose tissue-derived mesenchymal stem cell,liver injury repair,stem cell transplantation,stem cell repair,stem cell modification."Totally 62 articles of the latest research progress in this field were summarized and analyzed.RESULTS AND CONCLUSION:(1)Adipose tissue-derived mesenchymal stem cell as a potential stem cell with multi-directional differentiation has biological advantages in the treatment of acute liver injury.Compared with the other two major types of mesenchymal stem cell that is bone marrow mesenchymal stem cell and umbilical cord mesenchymal stem cell,they are more widely sourced,easily accessible and have fewer ethical issues,and more self-renewal than bone marrow mesenchymal stem cell.(2)Adipose tissue-derived mesenchymal stem cell may play a therapeutic role in acute liver injury by regulating immune responses,differentiating into hepatocytes,and secreting growth factors and exosomes.It can reduce the expression of inflammatory factors in serum and the infiltration of inflammatory cells in liver tissue,also can inhibit the pyroptosis and autophagy levels to promote regeneration of sinusoidal endothelial cells and hepatocyte,and ultimately improve liver damage.At present,no studies have shown which mechanism is the best mechanism for adipose tissue-derived mesenchymal stem cells to treat acute liver injury,and most opinions believe that these molecular mechanisms interact with each other to play a synergistic role in treatment.(3)Biomaterials modification and drug pretreatment can improve the efficacy of adipose tissue-derived mesenchymal stem cell in the treatment of acute liver injury.On the one hand,biomaterials and drug modifications can enhance the functions of adipose tissue-derived mesenchymal stem cell,such as enhancing the ability of proliferation and migration,increasing the level of growth factors secreted,and enhancing the anti-inflammatory ability and promoting the survival of adipose mesenchymal stem cells at the injury site.On the other hand,biomaterials and drug modifications can inhibit the activation of inflammatory cells at the injured site and promote the growth of blood to improve the success rate of transplantation.(4)In summary,adipose tissue-derived mesenchymal stem cell plays an important role in the treatment of acute liver injury by secreting growth factors and exosomes,regulating the immune response,and promoting liver regeneration.With the development of science and technology,biomaterials and drug modification can enhance the self-renewal ability of adipose tissue-derived mesenchymal stem cell and improve the local microenvironment of acute liver injury.It provides a new way to promote the clinical application of adipose tissue-derived mesenchymal stem cell in the treatment of acute liver injury.

Endoplasmic reticulum stress(ERS)plays a crucial role in cellular self-protection.In response to environmental changes,cells activate the unfolded protein response(UPR)and endoplasmic reticulum-associated protein degradation pathways to restore homeostasis.Increasing experimental evidence indicates that hypoxia and inflammation negatively impact synoviocytes in rheumatoid arthritis(RA),leading to the activation of three key endoplasmic reticulum transmembrane proteins:inositol-requiring enzyme 1,protein kinase R-like endoplasmic reticulum kinase,and activating transcription factor 6.These proteins mediate UPR pathways that are implicated in the pathological progression of RA.Targeting ERS-related molecules has emerged as a promising therapeutic strategy for RA.This article reviews the impact of ERS on the pathogenesis of RA and discusses drugs that modulate ERS as potential treatments for the disease.
