BACKGROUND:Cellular pyroptosis is an important pathological mechanism of cerebral ischemia/reperfusion injury.Buyang Huanwu Tang is a classic formula for the clinical treatment of ischemic stroke in traditional Chinese medicine,and cellular pyroptosis may be an effective target of Buyang Huanwu Tang in the treatment of cerebral ischemia/reperfusion injury.OBJECTIVE:To observe the effect and mechanism of Buyang Huanwu Tang on pyroptosis in brain tissues of middle cerebral artery occlusion/reperfusion rats.METHODS:Forty-eight Sprague-Dawley rats were randomly divided into sham operation group,model group,Astragalus membranaceus group and Buyang Huanwu Tang group.Except for the sham operation group,all groups were subjected to middle cerebral artery occlusion for ischemia for 2 hours and reperfusion for 72 hours.The rats in the Astragalus membranaceus group and Buyang Huanwu Tang group were continuously gavaged with the corresponding volume of drugs until ischemia and reperfusion for 72 hours after awakening from the modeling,once in the morning and once in the evening.Zea Longa score was used to observe the neurological deficits of rats.TTC staining was performed to observe cerebral infarct size in rats.Hematoxylin-eosin staining was used to observe the pathological changes of the brain tissue.Immunofluorescence was used to observe the co-expression of Tunel and Cleaved-Caspase-1 in the brain tissue and the expression of the junction protein ASC.Immunohistochemistry and western blot were used to detect the expression of pyroptosis-related proteins in rat brain tissues.RESULTS AND CONCLUSION:(1)Compared with the sham operation group,the neurological deficit score of rats was significantly higher in the model group(P<0.01),and compared with the model group,the neurological deficit score of rats was significantly lower in the Buyang Huanwu Tang group and the Astragalus membranaceus group(P<0.01).(2)Compared with the model group,the volume ratio of cerebral infarction was lower in the Astragalus membranaceus group and Buyang Huanwu Tang group(P<0.01).(3)In the model group,the nuclei of neuronal cells in the brain tissue were deeply stained or lysed,and arrangement of the cells was disorganized.Compared with the model group,the pathologic damage of the brain was less severe in the Buyang Huanwu Tang group and the Astragalus membranaceus group.(4)Compared with the sham operation group,the number of Tunel and Cleaved-Caspase-1 double-positive cells and immunofluorescence intensity of ASC in the brain tissue was significantly increased in the model group,and the expression of Cleaved-Caspase-1,NLRP3,interleukin 18,and interleukin 1β was significantly elevated in the model group(P<0.01).Compared with the model group,the number of Cleaved-Caspase-1 and Tunel double-positive cells,immunofluorescence intensity of ASC,and the expression of Cleaved-Caspase-1,NLRP3,interleukin 18,and interleukin 1β were all significantly decreased in the Buyang Huanwu Tang group and the Astragalus membranaceus group(P<0.01).The results indicate that Buyang Huanwu Tang and its monarch drug Astragalus membranaceus can effectively alleviate brain tissue injury in rats with middle cerebral artery occlusion and reperfusion,and its mechanism may be related to the inhibition of neuronal cell pyroptosis.

AIM:To observe the effects of Huangqi-Danggui mixture(HQDG)on the pyroptosis of brain tis-sues in rats with middle cerebral artery occlusion/reperfusion(MCAO/R),and to explore the mechanism of neuroprotec-tion provided by HQDG.METHODS:Sixty-four SD rats were randomly divided into 4 groups:sham group,model group,HQDG group,and Xuesaitong(XST)group.The infarct volume of brain tissues was observed by 2,3,5-triphenyl-tetrazolium chloride staining,while hematoxylin-eosin staining was used to observe the pathological changes of brain tis-sues.Immunofluorescence was employed to assess the expression of nucleotide-binding oligomerization domain-like recep-tor protein 3(NLRP3),cleaved caspase-1 and gasdermin D(GSDMD)in the ischemic penumbra of brain tissues.The se-rum levels of interleukin-1β(IL-1β)and IL-18 were measured using ELISA.Western blot was used to detect NLRP3,cleaved caspase-1,apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),IL-1β and IL-18 in brain tissues.RESULTS:Compared with sham group,the neurological deficit scores of the rats in model group were significantly increased(P<0.01),while those in HQDG and XST groups were significantly reduced compared with model group(P<0.01).The cerebral infarct volume ratio was significantly reduced in HQDG and XST groups compared with model group(P<0.01).The pathological damage of brain tissue in HQDG and XST groups was significantly reduced compared with model group.The positive rates of NLRP3,cleaved caspase-1 and GSDMD in the ischemic penumbra of brain tissues were significantly decreased in HQDG group compared with model group(P<0.01).The expression of pyrop-tosis-related proteins,NLRP3,cleaved caspase-1 and ASC,in the ischemic penumbra of brain tissues was significantly el-evated in model group compared with sham group(P<0.01),and significantly decreased in HQDG group compared with model group(P<0.01).The serum levels of IL-1β and IL-18 were significantly increased in model group compared with sham group(P<0.01),and significantly reduced in HQDG group compared with model group(P<0.01).CONCLU-SION:The HQDG effectively attenuates brain tissue injury in rats with MCAO/R,and its mechanism may be related to the inhibition of neural cell pyroptosis.

Objective To explore the diagnostic value of exhaled volatile organic compounds (VOCs) for cystic fibrosis (CF). Methods A systematic search was conducted in PubMed, EMbase, Web of Science, Cochrane Library, CNKI, Wanfang, VIP, and SinoMed databases up to August 7, 2024. Studies that met the inclusion criteria were selected for data extraction and quality assessment. The quality of included studies was assessed by the Newcastle-Ottawa Scale (NOS), and the risk of bias and applicability of included prediction model studies were assessed by the prediction model risk of bias assessment tool (PROBAST). Results A total of 10 studies were included, among which 5 studies only identified specific exhaled VOCs in CF patients, and another 5 developed 7 CF risk prediction models based on the identification of VOCs in CF. The included studies reported a total of 75 exhaled VOCs, most of which belonged to the categories of acylcarnitines, aldehydes, acids, and esters. Most models (n=6, 85.7%) only included exhaled VOCs as predictive factors, and only one model included factors other than VOCs, including forced expiratory flow at 75% of forced vital capacity (FEF75) and modified Medical Research Council scale for the assessment of dyspnea (mMRC). The accuracy of the models ranged from 77% to 100%, and the area under the receiver operating characteristic curve ranged from 0.771 to 0.988. None of the included studies provided information on the calibration of the models. The results of the Prediction Model Risk of Bias Assessment Tool (PROBAST) showed that the overall bias risk of all predictive model studies was high, and the overall applicability was unclear. Conclusion The exhaled VOCs reported in the included studies showed significant heterogeneity, and more research is needed to explore specific compounds for CF. In addition, risk prediction models based on exhaled VOCs have certain value in the diagnosis of CF, but the overall bias risk is relatively high and needs further optimization from aspects such as model construction and validation.

BackgroundIn recent years， the prevalence of depression among adolescents has risen steadily， alongside an increasing prominence of non-suicidal self-injury （NSSI） behaviors in this population， which may elevate suicide risk and constitute a serious public health problem. Negative emotions such as anxiety and depression are closely related to NSSI behaviors. Previous studies have predominantly relied on retrospective reports， limiting the ability to dynamically capture temporal relationships between emotional fluctuations and NSSI behaviors. Moreover， cognitive behavioral therapy （CBT） often lacks targeted design to address proximal triggers in interventions for NSSI behaviors. ObjectiveTo verify that anxiety as a proximal trigger factor for NSSI behaviors in adolescent patients with depression， and to evaluate the efficacy of modified CBT integrated with ecological momentary assessment （EMA） data in alleviating their anxiety and self-injury urges. MethodsA prospective cohort study design was adopted. A total of 132 adolescent patients with a history of NSSI behaviors who were treated at Jiujiang Fifth People's Hospital from January to December 2024 and met the diagnostic criteria for depression in the Diagnosed and Statistical Manual of Mental Disorders， fifth edition （DSM-5）. A smartphone-based EMA application to conduct natural situation emotions on participants for 14 consecutive days. The monitoring period spanned from 10∶00 to 22∶00 daily， with randomized assessments pushed every 2 hours. The assessment tools included the Self-rating Anxiety Scale （SAS） and the negative affect subscale of the Positive and Negative Affect Schedule （PANAS）， with real-time recording of NSSI behaviors and emotional states before and after their occurrence. Repeated measures analysis of variance was used to compare the dynamic changes in the scores of each scale before and after the episodes of NSSI behaviors. A modified CBT was administered to 83 participants who completed EMA data collection， with sessions conducted once weekly for 12 weeks. Anxiety levels were accessed using the SAS， and the self-injury urges was evaluated using the Ottawa Self-injury Inventory （OSI） before and after the intervention. ResultsEMA data revealed that SAS scores were significantly higher during the 1-2 hours before NSSI episodes compared to baseline periods ［（56.19±11.06）vs.（52.83±10.25），P<0.01］. SAS scores were positively correlated with the NSSI behavioral scores （r=0.460，P<0.01，95% CI：0.310-0.580）. After receiving modified CBT intervention， adolescent patients with depression demonstrated statistically significant decreases in both SAS scores ［（52.30±8.10） vs.（48.70±7.30），t（82）=4.820，P<0.01，Cohen's d=0.420］ and the OSI self-injury impulse subcale scores ［（12.80±2.70） vs.（9.60±2.50），t（82）=5.170，P<0.01，Cohen's d=0.510］ compared to their pre-intervention levels. ConclusionAnxiety may serve as a proximal trigger for NSSI behaviors in adolescent patients with depression. Modified CBT integrating EMA data could potentially alleviate their anxiety level and self-injury urges. ［Funded by Science and Technology Plan Project of Jiangxi Provincial Health Commission （number， SKJP220227629）］

Objective To investigate the diagnostic value of our regression model based on quantitative parameters of dual-energy CT and clinical features for stages T2 and T3 colorectal cancer.Methods A cross-section study was performed on 91 patients with colorectal cancer confirmed by postoperative pathology in our hospital from January 2022 to November 2023.All of them underwent dual-energy CT examination.According to the pathological T staging criteria of Chinese Colorectal Cancer Diagnosis and Treatment Standard(2020 Edition),they were divided into T2 group(n=43)and T3 group(n=48).Univariate analysis was used to compare the differences in quantitative CT parameters and clinical features between the 2 groups,and the obtained significant variables were employed to construct diagnosis models by univariate or multivariate logistic regression analysis.The area under receiver operating characteristic curve(AUC)of the CT parametric model and the model combined with clinical features was compared to evaluate the efficacy of diagnosing T2 and T3 stages.Results Univariate analysis showed that carcinoembryonic antigen(CEA),N stage,tumor location,tumor longest diameter(LD),CT value of virtual noncontrast(CT-VNC),fat fraction,electron density(Rho)and dual energy index(DEI)were significantly different between the T2 and T3 groups(P＜0.05).Multivariate logistic regression analysis found that N stage,tumor location,LD,fat fraction and DEI were independent risk factors for the diagnosis of stage T3.The AUC value of the model of above CT parameters in diagnosing stage T3 colorectal cancer was 0.671(95％CI:0.558～0.783),and the AUC value of the combined model of above CT parameters and clinical features was 0.886(95％CI:0.815～0.957),and statistical difference was observed in the AUC value between the combined model and the CT parametric model(P＜0.01).Conclusion The regression model constructed with dual-energy CT quantitative parameters combined with clinical features has high value in the preoperative diagnosis of stages T2 and T3 colorectal cancer before surgery.

Objective To analyze the correlations of autoimmune diseases(AIDs)with the risk of developing pancreatic endocrine and exocrine diseases.Methods A total of 451,497 participants from the UK Biobank were recruited,with the primary outcomes being pancreatic endocrine and exo-crine diseases.International Classification of Diseases 9/10(ICD9/10)codes were used to define each AIDs,the pancreatic endocrine and exocrine diseases.Multivariable Cox proportional hazards models were employed to assess the relationships between AIDs and pancreatic endocrine and exocrine diseases,with adjustments for age,gender,ethnicity,Townsend deprivation index,smoking,alcohol consumption,body mass index,waist circumference,hip circumference,hypertension,dyslipidemia,and gallstones.Results A total of 415,497 participants were included,among which 37,482 de-veloped pancreas-related diseases during follow-up.Among patients with AIDs,the proportions of those with pancreatic exocrine and endocrine diseases were significantly increased(P＜0.05).Rheumatoid arthritis[HR(95％CI):1.438(1.161 to 1.781)],ankylosing spondylitis[HR(95％CI):1.675(1.009 to 2.780)],ulcerative colitis[HR(95％CI):1.335(1.037 to 1.719)],and Crohn's disease[HR(95％CI):1.530(1.154 to 2.028)]were all associated with an increased risk of de-veloping pancreatic exocrine diseases(all P＜0.05);additionally,rheumatoid arthritis[HR(95％CI):1.119(1.004 to 1.248)],ulcerative colitis[HR(95％CI):1.324(1.175 to 1.491)],sys-temic sclerosis[HR(95％CI):2.08(1.355 to 3.191)],and Crohn's disease[HR(95％CI):1.394(1.197 to 1.624)]were also associated with an increased risk of developing pancreatic en-docrine diseases(all P＜0.05).Conclusion Overall AIDs and some specific AIDs are associated with an increased risk of developing pancreatic endocrine and exocrine diseases,and early preven-tion of pancreatic diseases in patients with AIDs should be emphasized in clinical practice.

AIM:To investigate the mechanism by which exosomes(EXOs)derived from neural stem cells(NSCs)pretreated with astragaloside IV(ASIV)alleviate brain damage in rats after ischemic stroke.METHODS:Rat NSCs were isolated from fetal rats within 24 h of birth,cultured for 3 d,and subsequently treated with ASIV for additional 5 d.The EXOs from untreated NSCs and ASIV-pretreated NSCs(ASIV-EXOs)were isolated via ultracentrifugation of the cell supernatant.These EXOs were characterized using Western blot to detect specific markers such as CD63,tumor sus-ceptibility gene 101(TSG101)and calnexin.Nanoparticle analysis was employed to determine the size,and the morpholo-gy of the EXOs was observed under electron microscope.Six to eight-week-old SD male rats were randomly assigned to 6 groups:sham group,middle cerebral artery occlusion/reperfusion(MCAO/R)model group,edaravone(EDA)treatment(MCAO/R+EDA)group,EXOs treatement(MCAO/R+EXOs)group and ASIV-EXOs treatment(MCAO/R+ASIV-EXOs)group.Tail vein injections were administered within 2 h following the successful establishment of the MCAO/R model.The Zea Longa method was utilized to evaluate neurological deficits,while the TTC method was employed to assess brain infarc-tion.Pathological changes were examined through HE staining,and TUNEL and caspase-1 immunofluorescence double staining were conducted to detect cellular pyroptosis.Serum levels of interleukin-1β(IL-1β)and IL-18 were measured us-ing ELISA,and Western blot was performed to evaluate the expression of caspase-1,nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3),apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),gasdermin D(GSDMD),and IL-18 proteins in the ischemic area of the rat cerebral cortex across all groups.RE-SULTS:The MCAO/R group exhibited significantly higher neurological deficit scores compared to the sham group(P＜0.01)and lower scores in the administered groups relative to the MCAO/R group(P＜0.05).Cerebral infarction was mark-edly increased in the MCAO/R group compared to the sham group(P＜0.01),whereas the infarction area was reduced in the administered groups compared to the MCAO/R group(P＜0.05).Serum levels of IL-1β and IL-18 were significantly el-evated in the MCAO/R group versus the sham group(P＜0.01)and were lower in the administered groups compared to the MCAO/R group(P＜0.01).Moreover,IL-1β and IL-18 levels in the MCAO/R+ASIV-EXOs group were lower than those in the MCAO/R+EXOs group(P＜0.05).HE staining revealed pronounced sieve-like infarction foci in the ischemic area of the rat cerebral cortex in MCAO/R group,characterized by disorganized neuronal arrangements,reduced or absent Nys-trom's vesicles,shrunken or fragmented nuclei,and numerous red neurons.In contrast,drug-treated groups exhibited milder pathological changes with clearer neuronal structures and a significant reduction in red neuron counts.Immunofluo-rescence double staining indicated a significant increase in double-positive cells in the MCAO/R group compared to the sham group(P＜0.01),with a decrease in double-positive cells in the administered groups relative to the MCAO/R group(P＜0.05)and a further reduction in the MCAO/R+ASIV-EXOs group compared to the MCAO/R+EXOs group(P＜0.05).The expression levels of caspase-1,NLRP3,ASC,IL-18 and GSDMD proteins in the ischemic region of the rat cerebral cortex were significantly reduced in the administered groups compared to the MCAO/R group(P＜0.01),with further re-duction observed in the MCAO/R+ASIV-EXOs group compared to the MCAO/R+EXOs group(P＜0.05).CONCLU-SION:Exosomes derived from ASIV-pretreated NSCs attenuate brain damage in ischemic stroke rats,potentially through a mechanism involving the inhibition of pyroptosis mediated by the NLRP3/caspase-1 pathway.
