Analyze interleukin-1β,interleukin-6,and tumor necrosis factor-αlevels in dry eye and the therapeutic effect of cyclosporine A

BACKGROUND Dry eye is a common eye disease.Artificial tears supplements are widely used for the treatment of dry eyes.However,multiple adverse effects have been observed in patients receiving long-term treatment with artificial tears,which may affect the therapeutic effect.AIM To analyze the characteristics of interleukin-1β(IL-1β),interleukin-6(IL-6),and tumor necrosis factor-alpha(TNF-α)levels in patients with dry eye and the therapeutic effect of artificial tears combined with cyclosporine A.METHODS A total of 124 dry eye patients treated at The First People’s Hospital of Xining from April 2020 to April 2022 were selected as the observation group,while 20 healthy individuals served as the control group during the same period.Levels of inflammatory markers,including IL-1β,IL-6,and TNF-α,were analyzed.The observation group was further divided into a study group and a control group,each consisting of 62 patients.The control group received artificial tears,whereas the study group received a combination of artificial tears and cyclosporine A.Inflammatory markers,Schirmer’s test(SIT),tear break-up time(TBUT),corneal fluorescein staining(CFS),National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25)scores,and adverse events(AEs)were compared between the two groups.RESULTS The observation group exhibited significantly elevated serum levels of IL-1β,IL-6,and TNF-αin comparison to the healthy group.Following treatment,the study group demonstrated substantial reductions in IL-1β,IL-6,and TNF-αlevels relative to the control group.Moreover,after treatment,the study group experienced a marked decrease in CFS scores and significant increases in both SIT and BUT levels when compared to the control group.Additionally,significant improvements were observed in the primary symptom of dry eye and secondary symptoms such as photophobia,foreign body sensation,fatigue,red eye,and burning sensation within the study group.Furthermore,post-treatment NEI-VFQ-25 scores across all dimensions exhibited significant enhancements in the study group compared to the control group(P<0.05).It is noteworthy that significant AEs were reported in both groups throughout the treatment period.CONCLUSION Cyclosporine A combined with artificial tears is effective in treating dry eye,yielding enhanced outcomes by improving SIT and TBUT levels,reducing CFS scores,and ameliorating vision-related quality of life.

Evaluating the role of interleukin-2 and interleukin-12 in pediatric patients with concurrent Mycoplasma pneumoniae and Epstein-Barr virus infections

BACKGROUND Mycoplasma pneumoniae(MP)frequently causes respiratory infections in children,whereas Epstein-Barr virus(EBV)typically presents subclinical manifestations in immunocompetent pediatric populations.The incidence of MP and EBV coinfections is often overlooked clinically,with the contributory role of EBV in pulmonary infections alongside MP remaining unclear.AIM To evaluate the serum concentrations of interleukin-2(IL-2)and interleukin-12(IL-12)in pediatric patients with MP pneumonia co-infected with EBV and assess their prognostic implications.METHODS We retrospectively analyzed clinical data from patients diagnosed with MP and EBV co-infection,isolated MP infection,and a control group of healthy children,spanning from January 1,2018 to December 31,2021.Serum IL-2 and IL-12 levels were quantified using enzyme-linked immunosorbent assay.Logistic regression was employed to identify factors influencing poor prognosis,while receiver operating characteristic(ROC)curves evaluated the prognostic utility of serum IL-2 and IL-12 levels in co-infected patients.RESULTS The co-infection group exhibited elevated serum IL-2 and C-reactive protein(CRP)levels compared to both the MP-only and control groups,with a reverse trend observed for IL-12(P<0.05).In the poor prognosis cohort,elevated CRP and IL-2 levels,alongside prolonged fever duration,contrasted with reduced IL-12 levels(P<0.05).Logistic regression identified elevated IL-2 as an independent risk factor and high IL-12 as a protective factor for adverse outcomes(P<0.05).ROC analysis indicated that the area under the curves for IL-2,IL-12,and their combination in predicting poor prognosis were 0.815,0.895,and 0.915,respectively.CONCLUSION Elevated serum IL-2 and diminished IL-12 levels in pediatric patients with MP and EBV co-infection correlate with poorer prognosis,with combined IL-2 and IL-12 levels offering enhanced predictive accuracy.

Interleukin-1β:Friend or foe for gastrointestinal cancers

Gastrointestinal(GI)cancer is a malignancy arising in the digestive system and accounts for approximately a third of increasing global cancer-related mortality,especially in the colorectum,esophagus,stomach,and liver.Interleukin-1β(IL-1β)is a leukocytic pyrogen recognized as a tumor progression-related cytokine.IL-1βsecretion and maturation in inflammatory responses could be regulated by nuclear factor-kappaB-dependent expression of NLR family pyrin domain containing 3,inflammasome formation,and activation of IL-1 converting enzyme.Several studies have documented the pro-tumorigenic effects of IL-1β in tumor microenvironments,promoting proliferation and metastatic potential of cancer cells in vitro and tumorigenesis in vivo.The application of IL-1β inhibitors is also promising for targeted therapy development in some cancer types.However,as a leukocytic pro-inflammatory cytokine,IL-1β may also possess anti-tumorigenic effects and be type-specific in different cancers.This editorial discusses the up-to-date roles of IL-1β in GI cancers,including underlying mechanisms and down-stream signaling pathways.Understanding and clarifying the roles of IL-1β would significantly benefit future therapeutic targeting and help improve therapeutic outcomes in patients suffering from GI cancer.

Low interleukin-10 level indicates a good prognosis in Salmonella enterica serovar typhimurium-induced pediatric hemophagocytic lymphohistiocytosis:A case report

BACKGROUND Secondary hemophagocytic lymphohistiocytosis(sHLH)triggered by Salmonella enterica serovar Typhimurium is rare in pediatric patients.There is no consensus on how to treat S.typhimurium-triggered sHLH.CASE SUMMARY A 9-year-old boy with intermittent fever for 3 d presented to our hospital with positive results for S.typhimurium,human rhinovirus,and Mycoplasma pneumoniae infections.At the time of admission to our institution,the patient’s T helper 1/T helper 2 cytokine levels were 326 pg/mL for interleukin 6(IL-6),9.1 pg/mL for IL-10,and 246.7 pg/mL for interferon-gamma(IFN-γ),for which the ratio of IL-10 to IFN-γwas 0.04.In this study,the patient received meropenem,linezolid,and cefoperazone/sulbactam in combination with high-dose methylprednisolone therapy(10 mg/kg/d for 3 d)and antishock supportive treatment twice.After careful evaluation,this patient did not receive HLH chemotherapy and recovered well.CONCLUSION S.Typhimurium infection-triggered sHLH patient had a ratio of IL-10 to IFN-γ≤1.33,an IL-10 concentration≤10.0 pg/mL,and/or an IFN-γconcentration≤225 pg/mL at admission.Early antimicrobial and supportive treatment was sufficient,and the HLH-94/2004 protocol was not necessary under these conditions.

Interleukin-35: A key player managing pre-diabetes and chronic inflammatory type 1 autoimmune diabetes

Interleukin-35(IL-35)is a novel protein comprising IL-12αand IL-27βchains.The IL12A and EBI3 genes are responsible for its production.The study of IL-35 has experienced a substantial increase in interest in recent years,as demonstrated by many research papers.Recent clinical studies have shown that individuals who do not have a C-peptide have notably reduced amounts of IL-35 in their blood serum.This is accompanied by a drop in the percentage of IL-35+Treg cells,regulatory B cells,and CD8+FOXP3+cells that produce IL-35.This article em-phasizes the potential significance of IL-35 expression in governing the immune response and its involvement in chronic inflammatory autoimmune diabetes in pancreatic inflammation.It demonstrates IL-35's ability to regulate cytokine proportions,modulate B cells,and protect against autoimmune diabetes.However,further investigation is necessary to ascertain the precise mechanism of IL-35,and meticulous planning is essential for clinical studies.

Effects of interleukin-10 treated macrophages on bone marrow mesenchymal stem cells via signal transducer and activator of transcription 3 pathway

BACKGROUND Alveolar bone defects caused by inflammation are an urgent issue in oral implant surgery that must be solved.Regulating the various phenotypes of macrophages to enhance the inflammatory environment can significantly affect the progression of diseases and tissue engineering repair process.AIM To assess the influence of interleukin-10(IL-10)on the osteogenic differentiation of bone marrow mesenchymal stem cells(BMSCs)following their interaction with macrophages in an inflammatory environment.METHODS IL-10 modulates the differentiation of peritoneal macrophages in Wistar rats in an inflammatory environment.In this study,we investigated its impact on the proliferation,migration,and osteogenesis of BMSCs.The expression levels of signal transducer and activator of transcription 3(STAT3)and its activated form,phos-phorylated-STAT3,were examined in IL-10-stimulated macrophages.Subsequently,a specific STAT3 signaling inhibitor was used to impede STAT3 signal activation to further investigate the role of STAT3 signaling.RESULTS IL-10-stimulated macrophages underwent polarization to the M2 type through substitution,and these M2 macrophages actively facilitated the osteogenic differentiation of BMSCs.Mechanistically,STAT3 signaling plays a crucial role in the process by which IL-10 influences macrophages.Specifically,IL-10 stimulated the activation of the STAT3 signaling pathway and reduced the macrophage inflammatory response,as evidenced by its diminished impact on the osteogenic differentiation of BMSCs.CONCLUSION Stimulating macrophages with IL-10 proved effective in improving the inflammatory environment and promoting the osteogenic differentiation of BMSCs.The IL-10/STAT3 signaling pathway has emerged as a key regulator in the macrophage-mediated control of BMSCs’osteogenic differentiation.

Exploring the role of interleukin-6 receptor blockade in epilepsy and associated neuropsychiatric conditions through a mendelian randomization study

BACKGROUND The interplay between inflammation,immune dysregulation,and the onset of neurological disorders,including epilepsy,has become increasingly recognized.Interleukin(IL)-6,a pro-inflammatory cytokine,is suspected to not only mediate traditional inflammatory pathways but also contribute to neuroinflammatory responses that could underpin neuropsychiatric symptoms and broader psychiatric disorders in epilepsy patients.The role of IL-6 receptor(IL6R)blockade presents an intriguing target for therapeutic intervention due to its potential to attenuate these processes.neuropsychiatric conditions due to neuroinflammation.METHODS Mendelian randomization(MR)analysis employing single nucleotide poly-morphisms(SNPs)in the vicinity of the IL6R gene(total individuals=408225)was used to evaluate the putative causal relationship between IL6R blockade and epilepsy(total cases/controls=12891/312803),focal epilepsy(cases/controls=7526/399290),and generalized epilepsy(cases/controls=1413/399287).SNP weights were determined by their effect on C-reactive protein(CRP)levels and integrated using inverse variance-weighted meta-analysis as surrogates for IL6R effects.To address potential outlier and pleiotropic influences,sensitivity analyses were conducted employing a variety of MR methods under different modeling assumptions.RESULTS The genetic simulation targeting IL6R blockade revealed a modest but significant reduction in overall epilepsy risk[inverse variance weighting:Odds ratio(OR):0.827;95%confidence interval(CI):0.685-1.000;P=0.05].Subtype analysis showed variability,with no significant effect observed in generalized,focal,or specific childhood and juvenile epilepsy forms.Beyond the primary inflammatory marker CRP,the findings also suggested potential non-inflammatory pathways mediated by IL-6 signaling contributing to the neurobiological landscape of epilepsy,hinting at possible links to neuroinflammation,psychiatric symptoms,and associated mental disorders.CONCLUSION The investigation underscored a tentative causal relationship between IL6R blockade and decreased epilepsy incidence,likely mediated via complex neuroinflammatory pathways.These results encouraged further in-depth studies involving larger cohorts and multifaceted psychiatric assessments to corroborate these findings and more thoroughly delineate the neuro-psychiatric implications of IL-6 signaling in epilepsy.The exploration of IL6R blockade could herald a novel therapeutic avenue not just for seizure management but also for addressing the broader psychiatric and cognitive disturbances often associated with epilepsy.

Effect of flurbiprofen combined with prednisolone on interleukin-6 in elderly surgery patients

Objective: To determine the effect of flurbiprofen combined with prednisolone on interleukin-6 in elderly surgery patients. Methods: In this double-blind randomized controlled study, patients aged 65 to 80 who were undergoing spinal fusion surgery for disc herniation were administered flurbiprofen 100 mg (P group, flurbiprofen group), prednisolone 0.6 mg/kg (D group, prednisolone group), prednisolone 0.6 mg/kg plus flurbiprofen 100 mg (P + D group, flurbiprofen + prednisolone group) or normal saline (S group, saline group) 15 minutes before the induction of anesthesia. Plasma samples were collected before surgery (T0) and on day 1 (T1), day 2 (T2) and day 3 (T3) following surgery. At the same time, systemic inflammatory response syndrome (SIRS) was assessed by SIRS criteria. The levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP) for collected samples were measured. Results: Other groups had significantly lower levels of IL-6, CRP and occurrence of SIRS than S group (p < 0.05). Compared to groups P and D, the levels of IL-6 and CRP in P + D group were significantly lower on T1 (p < 0.05). Peak levels of IL-6 in all groups were presented on T1 (p 0.05). The levels of CRP within three days were significantly different but did not show peak levels (p > 0.05). Conclusion: Compared to prednisolone or flurbiprofen, combining flurbiprofen with prednisolone in elderly surgery patients led to an increased suppression of IL-6.

Analysis of the Role of D-Dimer,Interleukin-6,and Interleukin-18 in Differential Diagnosis of Pediatric Refractory Mycoplasma pneumoniae Pneumonia

Objective:To analyze the value of D-dimer(D-D),interleukin-6(IL-6),and IL-18 in the differential diagnosis of children with refractory Mycoplasma pneumoniae pneumonia(RMPP).Methods:The medical records of 92 children with Mycoplasma pneumoniae pneumonia(MPP)treated in the hospital were selected for retrospective analysis from January 2023 to January 2024.After comprehensive examinations such as computed tomography examination of the chest,48 children with general Mycoplasma pneumoniae pneumonia(GMPP)were put in the GMPP group and 44 children with RMPP were grouped in the RMPP group.The IL-6,IL-18,and D-D levels were compared between the two groups,and the receiver operating characteristic(ROC)curves were plotted to analyze their value for differential diagnosis of RMPP.Results:The levels of IL-6,IL-18,and D-D in the RMPP group were higher than those in the GMPP group(P<0.05);the ROC curves showed that the specificity of the differential diagnosis of IL-6,IL-18,and D-D was higher,and their diagnostic value was significant.Conclusion:Determination of IL-6,IL-18,and D-D levels in children with MPP can further diagnose the children’s condition,which can help physicians formulate targeted treatment plans,and is of great significance to the improvement of the children’s condition,which is worthy of attention.

Efficacy of Laparoscopic Cholecystectomy in Treating Patients with Gallstones and Its Effect on Interleukin-6 and Tumor Necrosis Factor-α Levels

Objective:To investigate the efficacy of laparoscopic cholecystectomy in the treatment of patients with gallstones and its effect on the levels of interleukin-6(IL-6)and tumor necrosis factor-α(TNF-a).Methods:A total of 82 patients with gallstones admitted from July 2020 to July 2023 were recruited and allocated into control and observation groups using the random number table method,with 41 cases in each group.The patients were treated with laparoscopic cholecystectomy,with the anterior triangle anatomical approach to the gallbladder in the control group and the posterior triangle anatomical approach to the gallbladder in the observation group.The treatment effect and inflammatory factor levels of both groups were observed and compared.Results:When comparing the clinical outcomes of both patient groups,the key parameters evaluated included time to mobilization,duration of surgery,extubation time,and intraoperative bleeding.The observation group exhibited a significant advantage in these parameters compared to the control group(P<0.05).Regarding the levels of inflammatory factors between the two groups before and after treatment,there was no significant difference in values before treatment.However,following treatment,patients in the observation group showed significantly lower levels of IL-6,TNF-α,and C-reactive protein(CRP)compared to the control group(P<0.05).Conclusion:Patients undergoing laparoscopic cholecystectomy for gallstones can benefit from the implementation of the posterior triangular anatomical approach to the gallbladder,which not only enhances therapeutic efficacy but also offers significant advantages in reducing levels of IL-6,TNF-α,and CRP.Therefore,it is recommended for the widespread adoption of this treatment approach in clinical practice.

Neutrophil-derived interleukin-17A participates in neuroinflammation induced by traumatic brain injury

After brain injury, infiltration and abnormal activation of neutrophils damages brain tissue and worsens inflammation, but the mediators that connect activated neutrophils with neuroinflammation have not yet been fully clarified. To identify regulators of neutrophil-mediated neuroinflammation after traumatic brain injury, a mouse model of traumatic brain injury was established by controlled cortical impact. At 7 days post-injury(sub-acute phase), genome-wide transcriptomic data showed that interleukin 17 A-associated signaling pathways were markedly upregulated, suggesting that interleukin 17 A may be involved in neuroinflammation. Double immunofluorescence staining showed that interleukin 17 A was largely secreted by neutrophils rather than by glial cells and neurons. Furthermore, nuclear factor-kappaB and Stat3, both of which are important effectors in interleukin 17 A-mediated proinflammatory responses, were significantly activated. Collectively, our findings suggest that neutrophil-derived interleukin 17 A participates in neutrophil-mediated neuroinflammation during the subacute phase of traumatic brain injury. Therefore, interleukin 17 A may be a promising therapeutic target for traumatic brain injury.

Interleukin-1:an important target for perinatal neuroprotection?

Perinatal inflammation is a significant risk factor for lifelong neurodevelopmental impairments such as cerebral palsy.Extensive clinical and preclinical evidence links the severity and pattern of perinatal inflammation to impaired maturation of white and grey matters and reduced brain growth.Multiple pathways are involved in the pathogenesis of perinatal inflammation.However,studies of human and experimental perinatal encephalopathy have demonstrated a strong causative link between perinatal encephalopathy and excessive production of the pro-inflammatory effector cytokine interleukin-1.In this review,we summarize clinical and preclinical evidence that underpins interleukin-1 as a critical factor in initiating and perpatuating systemic and central nervous system inflammation and subsequent perinatal brain injury.We also highlight the important role of endogenous interleukin-1 receptor antagonist in mitigating interleukin-1-driven neuroinflammation and tissue damage,and summarize outcomes from clinical and mechanistic animal studies that establish the commercially available interleukin-1 receptor antagonist,anakinra,as a safe and effective therapeutic intervention.We reflect on the evidence supporting clinical translation of interleukin-1 receptor antagonist for infants at the greatest risk of perinatal inflammation and impaired neurodevelopment,and suggest a path to advance interleukin-1 receptor antagonist along the translational path for perinatal neuroprotection.

Drug-induced entero-colitis due to interleukin-17 inhibitor use;capsule endoscopic findings and pathological characteristics:A case report

BACKGROUND Interleukin-17(IL-17)inhibitors are known to cause exacerbation or new onset of inflammatory bowel disease upon administration.However,few reports have described characteristic endoscopic and histopathologic findings,and no small intestinal lesions have been reported so far.CASE SUMMARY A woman in her 60s with psoriasis was administered ixekizumab(IXE),an anti-IL-17A antibody,for the treatment of psoriasis.Twenty months after commencing treatment,the patient visited our hospital because of persistent diarrhea.Blood tests performed at the time of the visit revealed severe inflammation,and colonoscopy revealed multiple round ulcers throughout the colon.A tissue biopsy of the ulcer revealed infiltration of inflammatory cells and granuloma-like findings in the submucosal layer.Capsule endoscopy revealed multiple jejunal erosions.After the withdrawal of IXE,the symptoms gradually improved,and ulcer reduction and scarring of the colon were endoscopically confirmed.CONCLUSION To the best of our knowledge,17 reports have documented IL-17 inhibitorinduced entero-colitis with endoscopic images,endoscopic findings,and pathological characteristics,including the present case.Nine of these cases showed diffuse loss of vascular pattern,coarse mucosa/ulcer formation in the left colon,and endoscopic findings similar to those of ulcerative colitis.In the remaining eight cases,discontinuous erosions and ulcerations from the terminal ileum to the rectum were seen,with endoscopic findings similar to those of Crohn’s disease.In this case,the findings were confirmed by capsule endoscopy,which has not been previously reported.

6-Gingerol, asarinin, and deoxyschizandrin improve bronchial epithelium functions in an interleukin-13einduced BEAS-2B cell model

Objective:To explore the effects of 6-gingerol,asarinin,and deoxyschizandrindthe main components of Zingiber officinale(Willd.)Rosc.(Gan Jiang),Asarum heterotropoides f.var.mandshuricum(Maxim.)(Xi Xin),and Schisandra chinensis(Turcz.)Baill.(Wu Wei Zi),respectivelydon an interleukin(IL)-13einduced BEAS-2B cell model in vitro.Methods:The BEAS-2B cell model was established using 25 ng/mL IL-13 combined with 1%fetal bovine serum(FBS)in vitro.Mitoquinone mesylate(Mito-Q)treatment was used as a positive control group,and different concentrations of 6-gingerol,asarinin,and deoxyschizandrin were used to treat the models.The level of reactive oxygen species(ROS)production was detected by flow cytometry.The expression levels of LC3B,Beclin1,adenosine 50-monophosphate(AMP)eactivated protein kinase(AMPK),phosphory-lated-AMPeactivated protein kinase(P-AMPK),dynamin-related protein 1(DRP1),and mitochondrial fusion protein 2(MFN2)were detected by Western blot.Mitochondrial membrane potential(MMP)assay kit with JC-1 was utilized to detect the level of MMP.Results:The BEAS-2B cells exposed to 25 ng/mL IL-13 with 1%FBS showed an increased ROS level and a decreased MMP.6-Gingerol,asarinin,and deoxyschizandrin were able to downregulate ROS level and upregulate the MMP in the BEAS-2B model.Asarinin and deoxyschizandrin reduced the expression of autophagy protein LC3B,while deoxyschizandrin significantly increased the expression of DRP1 in the BEAS-2B model.Conclusion:6-Gingerol,asarinin,and deoxyschizandrin can reduce ROS generation and increase MMP,but have different regulatory effects on the expression of autophagy protein and mitochondrial mitotic protein.The three components have both synergistic and complementary effects in classic medicine compatibility.This study may provide an innovative strategy to reduce the lung inflammation related to IL-13.

Effect of T-regulatory cells and interleukin-35, interleukin-10, and transforming growth factor-beta on diffuse large B-cell lymphoma

BACKGROUND Diffuse large B-cell lymphoma(DLBCL)is an aggressive non-Hodgkin lymphoma that affects B lymphocytes.It can develop in the lymph nodes and can be localized or generalized.Despite DLBCL being considered potentially curable,little research has been conducted on the relationship between the body's immune response and DLBCL.AIM To study the expression and significance of T-regulatory cells(Tregs)interleukin(IL)-35,IL-10,and transforming growth factor-beta(TGF-β)in DLBCL.METHODS Data from 82 patients with DLBCL who were initially admitted to The First Affiliated Hospital of Ningbo University(Zhejiang Province,China)between January 2017 and June 2022 and treated with standard first-line regimens were reviewed.Three patients were lost to follow-up;thus,79 patients were included in the statistical analysis and then divided into three groups according to the evaluation of clinical efficacy:Incipient(new-onset and treatment-naïve),effectively treated,and relapsed-refractory.Thirty healthy individuals were included in the control group.The expression of peripheral blood T lymphocytes and their associated factors IL-35,IL-10,and TGF-βin the four groups were observed.RESULTS In contrast to the successfully treated and normal control groups,both the incipient and relapse-refractory groups exhibited greater proportions of CD4-positive(+)Tregs(P<0.05),whereas the proportion of CD8+Tregs did not differ substantially between the groups.Serum levels of IL-35 and IL-10 in the incipient and relapsed-refractory groups were higher than those in the effectively treated and normal control groups(P<0.05).There was no statistically significant distinction in the expression level of TGF-βbetween the groups(P>0.05).The correlation between IL-35 and IL-10 concentrations was significantly positive,with a correlation coefficient of 0.531(P<0.05).The correlation between IL-35 and TGF-βconcentration was significantly positive,with a correlation coefficient of 0.375(P<0.05).The correlation between IL-10 and TGF-βconcentration was significantly positive,with a correlation coefficient of 0.185(P<0.05).The expression concentrations of IL-35,IL-10 and TGF-βwere apparently and positively correlated(P<0.05).CONCLUSION Tregs IL-35,and IL-10 may be closely associated with the occurrence and development of DLBCL and the detection of related indices may be helpful in the analysis of disease prognosis.

Hepatic vagotomy blunts liver regeneration after hepatectomy by downregulating the expression of interleukin-22

BACKGROUND Rapid regeneration of the residual liver is one of the key determinants of successful partial hepatectomy(PHx).At present,there is a lack of recognized safe,effective,and stable drugs to promote liver regeneration.It has been reported that vagus nerve signaling is beneficial to liver regeneration,but the potential mechanism at play here is not fully understood.AIM To explore the effect and mechanism of hepatic vagus nerve in liver regeneration after PHx.METHODS A PHx plus hepatic vagotomy(Hv)mouse model was established.The effect of Hv on liver regeneration after PHx was determined by comparing the liver regeneration levels of the PHx-Hv group and the PHx-sham group mice.In order to further investigate the role of interleukin(IL)-22 in liver regeneration inhibition mediated by Hv,the levels of IL-22 in the PHx-Hv group and the PHx-sham group was measured.The degree of liver injury in the PHx-Hv group and the PHx-sham group mice was detected to determine the role of the hepatic vagus nerve in liver injury after PHx.RESULTS Compared to control-group mice,Hv mice showed severe liver injury and weakened liver regeneration after PHx.Further research found that Hv downregulates the production of IL-22 induced by PHx and blocks activation of the signal transducer and activator of transcription 3(STAT3)pathway then reduces the expression of various mitogenic and anti-apoptotic proteins after PHx.Exogenous IL-22 reverses the inhibition of liver regeneration induced by Hv and alleviates liver injury,while treatment with IL-22 binding protein(an inhibitor of IL-22 signaling)reduce the concentration of IL-22 induced by PHx,inhibits the activation of the STAT3 signaling pathway in the liver after PHx,thereby hindering liver regeneration and aggravating liver injury in PHx-sham mice.CONCLUSION Hv attenuates liver regeneration after hepatectomy,and the mechanism may be related to the fact that Hv downregulates the production of IL-22,then blocks activation of the STAT3 pathway.

Clinical analysis between serum 25-hydroxyvitamin D3, interleukin-6 levels and febrile convulsion in children

Objective:To investigate the relation between febrile convulsions and 25hydroxy-vitamin D_(3)[25-(OH)D_(3)]and interleukin-6(IL-6)levels in children.Methods:241 children(divided into simple febrile convulsions and complex febrile convulsions),who were diagnosed with febrile convulsions at the Women and Children's Medical Center of Hainan Province from January 2017 to October 2022,were selected into the febrile convulsions group;100 healthy children,who had no uncomfortable symptoms and attended the outpatient clinic of the Women and Children's Medical Center of Hainan Province for physical examination,for the control group.All the subjects measured the serum 25-(OH)D_(3) and IL-6 levels,and clinical information,such as age,gender and season,was recorded.Results:1)Serum 25-(OH)D_(3) levels in the febrile convulsion group were significantly lower than in the healthy control group(78.77±20.37 nmol/L versus 96.55±29.74 nmol/L,respectively),and there was a statistically significant between the two groups(t value-6.359,P<0.001).Serum IL-6 levels in the febrile convulsion group were significantly higher than in the healthy control group,and there was a statistically significant between the two groups(Z value of-14.291,P<0.001).2)Serum 25-(OH)D_(3) levels in children with complex febrile convulsions were significantly lower than those in children with simple febrile convulsions,and the difference between the two groups was statistically significant(t-value of 6.612,P<0.05).IL-6 levels were higher in children with complex febrile convulsions than in children with simple febrile convulsions,and the difference between the two groups was statistically significant(Z value-10.151,P<0.001).The difference in the severity of febrile convulsions was statistically significant in serum 25-(OH)D_(3) levels(x^(2)=29.83,P<0.001).3)The results of correlation analysis showed that serum 25-(OH)D_(3) level was negatively correlated with febrile convulsion(γ=-0.393,P<0.05);serum 25-(OH)D_(3) level was positively correlated with that(γs=0.328,P<0.05).4)The correlation analysis results showed that the serum 25-(OH)D_(3) level was negatively correlated with the clinical characteristics of febrile convulsion(γ=-0.393,P<0.05).However,serum IL-6 water is positively correlated with it(γs=0.328,P<0.05).4)In contrast,there was no statistically significant difference in serum 25-(OH)D_(3) levels among children with febrile convulsions in different seasons(P>0.05).Conclusions:There is a correlation between febrile convulsion and serum levels of 25-(OH)D_(3) and IL-6.25-(OH)D_(3) and IL-6 may participate in the pathogenesis of febrile convulsion.
