AIM: To investigate the influence of relevant inflammatory markers in peripheral blood on the progression of neovascular glaucoma(NVG)secondary to diabetic retinopathy(DR)patients.METHODS: Retrospective case-control study. Patients were categorized into two groups based on the presence or absence of NVG: those with proliferative diabetic retinopathy(PDR)alone(PDR group, n=148)and those with NVG secondary to PDR(NVG secondary to PDR group, n=142). Peripheral blood inflammatory markers were evaluated, including white blood cell-related indices, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), monocyte-to-lymphocyte ratio(MLR), and systemic immune-inflammation index(SII). The distinctions in peripheral blood inflammatory markers between the two groups of patients and their relationships with NVG secondary to PDR were analyzed.RESULTS:No statistically significant differences were observed in basic characteristics between the two groups, confirming their comparability. However, significant differences were found in eosinophil percentage and MLR between the PDR group and the NVG secondary to PDR group(all P<0.05), with both values being significantly higher in the NVG secondary to PDR group. Multivariate Logistic regression analysis revealed that the eosinophil percentage and the MLR were factors influencing the development of patients with NVG secondary to PDR.CONCLUSION: Eosinophil percentage and MLR may be associated with the progression of PDR to NVG, and could serve as potential predictive markers for NVG development in PDR patients.

Objective: To investigate the attention cognitive function and symptom correlations of school aged children with attention deficit hyperactivity disorder (ADHD)using event related potential (ERP) technology, so as to provide references for the early diagnosis of children with ADHD. Methods: A total of 52 school aged children diagnosed with ADHD at the outpatient department of the Third Affiliated Hospital of Zhengzhou University from September 2022 to September 2024 and 50 age /sex matched healthy controls were selected. The ERP experiment adopted the auditory Oddball task to conduct comparative analyses of the amplitude and latency of the mismatch negative(MMN) at the Fz, Cz, and Pz points of the scalp electrode and the P3a component respectively. The symptom assessment scales adopted the Swanson,Nolan,and Pelham-Ⅳ Rating Scale (SNAP-Ⅳ) and the Parent Symptom Questionnaire (PSQ), which were filled out by the parents. Spearman correlation analysis was used to analyze the correlation between ERP components and symptoms in schoolaged children with ADHD. Results: The latency of MMN components in the healthy control group on the Fz lead was (188.30±2.06)ms, and the amplitude was (-15.54±1.35)μV; the latency of the P3a component on the Pz lead was (312.82±7.80)ms, and the amplitude was (3.80±0.18)μV. The latency of MMN components in the ADHD group on the Fz lead was (188.94±1.39)ms, and the amplitude was (-14.78±1.40)μV; the latency of the P3a component on the Pz lead was (317.21±5.65)ms, and the amplitude was (3.70±0.13)μV. Compared with normal children, the MMN of children with ADHD had smaller amplitudes in the Fz and Cz leads, and the P3a had greater latency and smaller amplitudes in the Cz and Pz leads ( t =2.79,2.20；-2.04，-3.25；2.35,3.21， P <0.05). Correlation analysis showed that the latency of MMN in children with ADHD was positively correlated with the inattention score in the SNAP-Ⅳ( r =0.22), and the amplitude of MMN was negatively correlated with the inattention score in the SNAP-Ⅳ and the learning problem score in PSQ ( r = -0.26 , -0.34)( P <0.05). The latency of P3a was positively correlated with the scores of inattention in the SNAP-Ⅳ and the score of learning problems in the PSQ ( r =0.26 ,0.24); the amplitude of P3a was negatively correlated with the scores of attention deficit and hyperactivity/impulsivity in the SNAP-Ⅳ and the scores of learning problems and impulsivity/hyperactivity in the PSQ( r = -0.26 , -0.22, -0.25,-0.32)( P <0.05). Conclusions School aged ADHD children exhibit abnormal MMN/P3a components, indicating attention related cognitive dysfunction. Symptoms such as inattention, learning problems and hyperactivity/impulsivity in children with ADHD are related to abnormal components of MMN and P3a.

OBJECTIVES: To investigate the therapeutic mechanism of 2,6-dimethoxy-1,4-benzoquinone (DMQ) for alleviating dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. METHODS: Eighteen male C57BL/6J mice were equally randomized into control group, DSS group and DMQ treatment group. In DSS and DMQ groups, the mice were treated with DSS in drinking water to induce UC, and received intraperitoneal injections of sterile PBS or DMQ (20 mg/kg) during modeling. The changes in body weight, disease activity index (DAI), colon length, spleen weight, and colon histological scores of the mice were examined, and the percentages of Th17 and IFN-γ⁺ CD8⁺ T cells in the mesenteric lymph nodes and spleen were analyzed using flow cytometry. The expressions of tight junction proteins (Occludin and ZO-1), proteins associated with inflammasome activation (caspase-1 and p20), IL-1β and TNF-α in the colon tissues were detected using Western blotting or ELISA. In the cell experiment, mouse bone marrow-derived macrophages (BMDMs) primed with lipopolysaccharide (LPS) were treated with DMQ, followed by stmulation with nigericin to activate the classical NLRP3 inflammasome pathway. In cultured human peripheral blood mononuclear cells (PBMCs) treated with either LPS alone or LPS plus nigericin, the effects of DMQ on inflammasome activation, pyroptosis, and cytokine release were evaluated via Western blotting, ELISA, and flow cytometry. RESULTS: In DSS-treated mice, DMQ treatment significantly alleviated DSS-induced body weight loss, colon shortening, spleen enlargement, and colon inflammation. The DMQ-treated mice showed significantly reduced percentages of Th17 cells and IFN-γ⁺ CD8⁺ T cells in the mesenteric lymph nodes and spleen, with increased occludin and ZO-1 expressions and decreased caspase-1 expression in the colon tissue. DMQ obviously inhibited classical NLRP3 inflammasome activation in mouse BMDMs and both the classical and alternative pathways of NLRP3 activation in human PBMCs, causing also suppression of caspase-1-dependent pyroptosis. CONCLUSIONS DMQ ameliorates DSS-induced UC in mice by inhibiting NLRP3 inflammasome activation.

Objective To investigate the value of integrin subunit αM(ITGAM)and integrin subunit β2(ITGB2)levels in peripheral blood mononuclear cells(PBMC)in the diagnosis and prognosis evaluation for patients with severe acute pancreatitis(SAP)complicated with acute lung injury(ALI).Methods A total of 205 patients with SAP admitted from November 2022 to February 2024 in the hospital were selected,and they were divided into ALI group(103 cases)and non-ALI group(102 cases)according to whether they were com-plicated with ALI.Meanwhile,110 healthy people who underwent the physical examination were selected as the control group.The differences of the levels of ITGAM and ITGB2 in PBMC in different groups were com-pared.Logistic regression was used to analyze the influencing factors for ALI in patients with SAP.The re-ceiver operating characteristic(ROC)curve was used to analyze the diagnostic value of levels of ITGAM and ITGB2 in PBMC for SAP patients complicated with ALI and the predictive value for poor prognosis.Results The levels of ITGAM,ITGB2 in PBMC,and serum amylase and urine amylase levels in ALI group were higher than those in non-ALI group and control group(P＜0.05).Multivariate Logistic regression anal-ysis showed that the increase of ITGAM,ITGB2 and serum amylase levels were risk factors for ALI in pa-tients with SAP(P＜0.05).ROC curve results showed that the area under the curve(AUC)of ITGAM com-bined with ITGB2 in diagnosing ALI in patients with SAP was significantly higher than those of ITGAM and ITGB2 alone(P＜0.05).The levels of ITGAM and ITGB2 in PBMC in the poor prognosis group were higher than those in the good prognosis group(P＜0.05).ROC curve results showed that the AUC of ITGAM com-bined with ITGB2 in predicting poor prognosis in patients with SAP complicated with ALI was significantly higher than those of ITGAM and ITGB2 alone(P＜0.05).Conclusion Increased levels of ITGAM and IT-GB2 in PBMC are risk factors for ALI in patients with SAP.ITGAM combined with ITGB2 has a good predic-tive efficacy for the poor prognosis in patients with SAP complicated with ALI,which has important value in clinical practice and is expected to become potential biomarkers.

Objective:This study investigated the awareness and consumption of Trogia venenata among populations in regions affected by Yunnan unexplained sudden death (YUSD). The findings aim to support etiological research on YUSD and contribute to the formulation of preventive measures against Trogia venenata poisoning. Methods:This study was a case-control study. From 2018 to 2021, surveys were conducted in 90 villages across 25 counties within YUSD-affected areas in Yunnan Province. Households with YUSD cases were designated as case households, whereas households without YUSD cases served as controls, ande were selected through convenience sampling at a 3:1 ratio. An enhanced questionnaire was designed to collect information on the consumption of Trogia venenata, and symptoms following consumption. Frequency data were presented as percentages, and group comparisons were conducted using χ 2 tests or Fisher’s exact tests. Results:A total of 711 questionnaires were collected (response rate: 100%), comprising 175 case households and 536 control households. Trogia venenata was present in 80.82% of the villages surveyed. Among the 711 households, 15.89% reported consuming Trogia venenata, primarily through stir-frying (53.10%), followed by boiling (29.20%), boiling and stir-frying (15.93%), and steaming (1.77%). Most households (94.69%) consumed fresh fruiting bodies, with 69.02% consuming them fewer than three times annually. The consumption rates were higher among the case households than among the control households. Of the 113 households with a history of Trogia venenata consumption, 35.40% reported symptoms such as nausea, vomiting, and limb soreness. The proportions of affected families in each group were compared according to their source, cooking method, fruiting body status and consumption frequency. The proportion of affected families with high consumption frequency (≥3 times/year) was higher than that with low consumption frequency (<3 times/year). Among 421 YUSD cases, 63 cases (14.96%) had a history of Trogia venenata consumption before death, with 43 cases showing symptoms within the longest known latency period (14 d) for poisoning by this mushroom. Conclusions:Trogia venenata is prevalent in 80.82% of YUSD-affected regions, with 16.67% of the population reporting its consumption, predominantly as fresh fruiting bodies prepared by stir-frying or boiling. Confirmed Trogia venenata consumption was identified in 14.96% of YUSD cases, suggesting that mushroom poisoning is a significant risk factor for YUSD. Ongoing health education and interventions are critical for mitigating the risk of Trogia venenata poisoning.

Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.
