Objective: To explore the association between vegetable intake with glucose and lipid metabolism levels among school aged children, so as to provide scientific basis for dietary intervention on children s metabolic health. Methods: Based on a natural population cohort in Jiulongpo District and Fengdu County of Chongqing, 2 133 school aged children aged 6-9 years were enrolled in the baseline survey in 2014, and 2 029 children completed the follow up in 2019. Questionnaire surveys were used to collect vegetable intake, general demographic and lifestyle data. Height, weight and waist circumference were measured, and glucose and lipid metabolism indicators such as fasting blood glucose (FBG), triglyceride (TG) and total cholesterol (TC), low densith lipoprotein triglyceride (LDL-C), high densith lipoprotein triglyceride (HDL-C) were detected. Mann-Whitney U test and Kruskal-Wallis H test were used for intergroup comparisons in multivariate analysis, and mixed effects linear regression model was used to analyze the association between vegetable intake and glucose and lipid metabolism. Results: The levels of FBG, TG, TC, HDL-C and LDL-C at baseline and follow up were [4.09(3.90,4.48), 0.84(0.60,1.14), 3.49(3.09,3.91), 1.25(1.09,1.46), 1.69 ( 1.39 ,2.02)；4.31(4.00,4.64), 0.92(0.71,1.22), 3.49(3.12,3.87), 1.36(1.16,1.57), 1.77(1.51,2.06)] mmol/L, respectively. Among these indicators, FBG, TG, HDL-C and LDL-C all increased significantly ( Z =-12.08, -7.82, -9.82, -5.37, all P < 0.01 ). The detection rate of low HDL-C levels at follow up (13.11%) was significantly lower than that at baseline (18.10%) ( χ 2=19.57, P <0.05). At baseline, there were significant differences in FBG, TC, TG, HDL-C and LDL-C among children with different vegetable intake levels ( H =68.47, 30.16, 11.02, 13.27, 44.70); at followup, only HDL-C showed significant intergroup differences ( H =13.10)(all P <0.05). Mixed effects linear regression model showed that after adjusting for confounding factors, vegetable intake was significantly negatively correlated with blood glucose levels among school aged children ( β=-0.03, 95%CI = -0.05 to -0.01, P <0.01). Conclusion Higher vegetable intake can independently reduce the risk of abnormal blood glucose in school aged children, which is of great significance for maintaining glucose metabolic health.

Objective:To investigate the efficacy of a domestically developed small esophageal cooling device in implementing targeted temperature management (TTM) after resuscitation and its impact on organ injury using a porcine model of cardiac arrest and resuscitation.Methods:Thirty healthy male domestic white pigs were randomly divided into four groups using a random number table: sham (S group, n=6), normothermia (NT group, n=8), surface cooling (SC group, n=8), and esophageal cooling (EC group, n=8). The S group underwent only surgical preparation, while the other groups were subjected to 12 minutes of ventricular fibrillation followed by 6 minutes of cardiopulmonary resuscitation to establish cardiac arrest. The S and NT groups maintained a core temperature of (37.5±0.5)°C using a surface blanket. In the SC and EC groups, therapeutic hypothermia was induced post-resuscitation via surface blanket or esophageal cooling catheter to achieve a target temperature of 34°C, maintained the target temperature (34±0.5)°C for 6 hours, followed by controlled rewarming at 0.5°C/h to 37°C. Core temperature was continuously monitored for 12 hours post-resuscitation. Hemodynamic parameters, including stroke volume (SV), global ejection fraction (GEF), extravascular lung water index (ELWI), and pulmonary vascular permeability index (PVPI), were assessed using pulse indicator continuous cardiac output (PiCCO) monitoring. Serum levels of cardiac troponin I (cTnI), neuron-specific enolase (NSE), creatinine (Cr), and intestinal fatty acid-binding protein (IFABP) were measured via ELISA at 2, 6, 12, and 24 hours post-resuscitation. Neurological outcomes were evaluated at 24 hours using the neurological deficit score (NDS) and cerebral performance category (CPC). Continuous variables were analyzed using one-way ANOVA. Results:During TTM, the EC group exhibited a faster cooling rate [(1.52±0.18)°C/h vs. (0.94±0.32)°C/h, P<0.05] and shorter time to target temperature [(2.32±0.43) h vs. (3.78±0.82) h, P<0.05] compared to the SC group, with comparable maintenance and rewarming ( P>0.05). Compared to the S group, the NT, SC, and EC groups demonstrated significant post-resuscitation multi-organ injury, characterized by reduced SV and GEF, elevated ELWI and PVPI, and increased serum cTnI, NSE, Cr, IFABP, NDS, and CPC scores (all P<0.05). Relative to the NT group, the SC and EC groups showed improved SV (at 1 h post-resuscitation), GEF (at 1, 2, 4, and 6 h), ELWI (at 12 h), and reduced cTnI and NSE (at 6 h), Cr and IFABP (at 2 h), and NDS and CPC (at 24 h) (all P<0.05). Compared to the SC group, the EC group exhibited lower PVPI (at 12 h), reduced cTnI, Cr, and IFABP (at 2 h), decreased NSE (at 2, 12, and 24 h), and improved NDS (at 24 h) (all P<0.05). Conclusions:In a porcine model of cardiac arrest and resuscitation, the domestic esophageal cooling device facilitated rapid induction, stable maintenance, and controlled rewarming during TTM, outperforming traditional surface cooling. This approach demonstrated superior organ protection, warranting further investigation.

Objective:To compare the consistency of lymphoma multigene detection panels based on next-generation sequencing (NGS) with FISH detection of B-cell lymphoma gene rearrangement.Methods:From January 2019 to May 2023, fusion genes detected by lymphoma-related 413 genes that targeted capture sequencing of 489 B-cell lymphoma tissues embedded in paraffin were collected from Henan Cancer Hospital, and the results were compared with simultaneous FISH detection of four break/fusion genes: BCL2, BCL6, MYC, and CCND1. Consistency was defined as both methods yielding positive or negative results for the same sample. The relationship between fusion mutation abundance in NGS and the positivity rate of cells in FISH was also analyzed.Results:Kappa consistency analysis revealed high consistency between NGS and FISH in detecting the four B-cell lymphoma-related gene rearrangement ( P<0.001 for all) ; however, the detection rates of positive individuals differed for the four genes. Compared with FISH, NGS demonstrated a higher detection rate for BCL2 rearrangement, a lower detection rate for BCL6 and MYC rearrangement, and a similar detection rate for CCND1 rearrangement. No correlation was found between fusion mutation abundance in NGS and the positivity rate of cells in FISH. Conclusions:NGS and FISH detection of B-cell lymphoma gene rearrangement demonstrate overall good consistency. NGS is superior to FISH in detecting BCL2 rearrangement, inferior in detecting MYC rearrangement, and comparable in detecting CCND1 rearrangement.

Objective To investigate the effect of acacetin on oxidative stress injury in diabetic cataract(DC)rats and its regulation of sirtuin 1(Sirt1)/adenosine monophosphate-activated protein kinase(AMPK)/nuclear factor-erythroid 2-related factor 2(Nrf2)signaling pathway.Methods Sixty SD rats were randomly divided into the control group,model group,low-dose acacetin group,high-dose acacetin group,and acacetin+Sirt1 inhibitor(EX527)group.DC rat models were constructed except for the control group.Rats in the low-dose and high-dose acacetin groups were injected with 10 mg·kg-1 and 20 mg·kg-1 acacetin subcutaneously through the neck,twice a day,respectively.Rats in the acacetin+EX527 group were injected with 20 mg·kg-1 acacetin subcutaneously through the neck,twice a day;additionally,3.5 mg·kg-1 EX527 was administered subcutaneously through the osmotic micro-pump for 4 weeks.The same amount of nor-mal saline was pumped into rats in the rest groups for 4 weeks.After administration,blood pressure and fasting blood glu-cose(FBG)were measured.The lens opacity was observed under the slit lamp irradiation,and the histopathological chan-ges in the lens were observed after hematoxylin-eosin staining.Enzyme-linked immunosorbent assay was performed to de-termine the serum levels of malondialdehyde(MDA),superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),in-terleukin(IL)-6,and IL-1 β.Western blot was applied to detect the expression levels of Sirt1,phosphorylated AMPK(p-AMPK),AMPK,and Nrf2 proteins.Results Compared with the control group,the lens epithelial cells(LECs)of rats in the model group showed patchy and striped shapes,and migration and aggregation occurred;the systolic blood pres-sure(SBP),FBG,lens opacity score,and the levels of MDA,IL-6 and IL-1 β increased,while the expression levels of SOD,GSH-Px,Sirt1,p-AMPK/AMPK,and Nrf2 proteins decreased(all P＜0.05).Compared with the model group,the migration and aggregation of LECs improved in the low-dose and high-dose acacetin groups,the SBP,FBG,lens opacity score,and the levels of MDA,IL-6 and IL-1 β decreased,while the expression levels of SOD,GSH-Px,Sirt1,p-AMPK/AMPK,and Nrf2 proteins increased(all P＜0.05).Compared with the high-dose acacetin group,the morphological chan-ges and aggregation of LECs in the acacetin+EX527 group were more significant,the SBP,FBG,lens opacity score,and the levels of MDA,IL-6 and IL-1 β increased,while the expression levels of SOD,GSH-Px,Sirt1,p-AMPK/AMPK,and Nrf2 proteins decreased(all P＜0.05).Conclusion Acacetin may protect DC rats from oxidative stress injury by activating the Sirt1/AMPK/Nrf2 pathway.

Objective To investigate the effect of total flavone of Cydonia oblonga on oxidative damage of human lens epithelial cells induced by high glucose and its mechanism.Methods A cell injury model was established by inducing human lens epithelial cells with high glucose.Human lens epithelial cells were cultured in the medium containing 30 mmol·L-1 glucose for 24 h,which was recorded as the high glucose group.Cells in the control group were cultured in a medium con-tainning 5.5 mmol·L-1 glucose for 24 h.Human lens epithelial cells were inoculated into 96-well plates with 5 × 103 cells per well,and treated with mediums containing 10 mmol·L-1,20 mmol·L-1,and 40 mmol·L-1 total flavone of Cydonia ob-longa combined with 30 mmol·L-1 glucose for 24 h.They were recorded as high glucose+low total flavone of Cydonia oblonga group,high glucose+medium total flavone of Cydonia oblonga group,and high glucose+high total flavone of Cydonia oblonga group.Human lens epithelial cells were transfected with anti-miR-NC and anti-miR-370 with Lipo-fectamine2000 transfection reagent,and treated with 30 mmol·L-1 glucose for 24 h,which were recorded as high glucose+anti-miR-NC group and high glucose+anti-miR-370 group.Human lens epithelial cells were transfected with miR-NC and miR-370 mimics,and treated with medium containing 30 mmol·L-1 glucose and 40 mmol·L-1 total flavone of Cydonia oblonga for 24 h,which were labeled as high glucose+total flavone of Cydonia oblonga+miR-NC group and high glucose+total flavone of Cydonia oblonga+miR-370 group.The activities of superoxide dismutase(SOD)and cata-lase(CAT),and the content of malondialdehyde(MDA)were measured by Enzyme-linked immunosorbent assay;flow cy-tometry was applied to detect apoptosis rate;quantitative reverse transcription polymerase chain reaction was applied to detect the expression level of miR-370;Western blot was applied to detect the expression of apoptosis-related proteins.Results Compared with the control group,the activities of SOD and CAT decreased and the content of MDA increased in the human lens epithelial cells of the high glucose group,and the differences were statistically significant(all P＜0.05);compared with the high glucose group,the activities of SOD and CAT significantly increased and the content of MDA signifi-cantly decreased in the high glucose+low total flavone of Cydonia oblonga group,the high glucose+medium total fla-vone of Cydonia oblonga group and the high glucose+high total flavone of Cydonia oblonga group(all P＜0.05).Com-pared with the control group,apoptosis rate,and protein expressions of Caspase-3 and Caspase-9 of human lens epithelial cells in the high glucose group significantly increased(all P＜0.05);compared with the high glucose group,the apoptosis rate,Caspase-3 and Caspase-9 protein expressions of human lens epithelial cells in the high glucose+low total flavone of Cydonia oblonga group,high glucose+medium total flavone of Cydonia oblonga group,and high glucose+high total fla-vone of Cydonia oblonga group significantly decreased(all P＜0.05).The expression levels of miR-370 in human lens epi-thelial cells were 1.00±0.00,4.04±0.36,3.22±0.24,2.42±0.23 and 1.62±0.14 in the control group,high glucose group,high glucose+low total flavone of Cydonia oblonga group,high glucose+medium total flavone of Cydonia oblon-ga group,and high glucose+high total flavone of Cydonia oblonga group,respectively.There was a statistically different significance among the five groups(F=256.138,P＜0.05).Compared with the high glucose+anti-miR-NC group,the ex-pression of miR-370 significantly decreased,the activities of SOD and CAT significantly increased,and the content of MDA significantly decreased in human lens epithelial cells of the high glucose+anti-miR-370 group(all P＜0.001).Compared with the high glucose+anti-miR-NC group,apoptosis rate,and protein expressions of Caspase-3 and Caspase-9 of the hu-man lens epithelial cells in the high glucose+anti-miR-370 group significantly decreased(all P＜0.001).Compared with the high glucose+total flavone of Cydonia oblonga+miR-NC group,the activities of SOD and CAT significantly de-creased,and the content of MDA,apoptosis rate,and protein expressions of Caspase-3 and Caspase-9 significantly in-creased in the human lens epithelial cells of high glucose+total flavone of Cydonia oblonga+miR-370 group(all P＜0.001).Conclusion The expression of miR-370 increases in high glucose-induced human lens epithelial cells.Total fla-vone of Cydonia oblonga can inhibit the oxidative stress and apoptosis of high glucose-induced human lens epithelial cells,and the mechanism may be related to the decreased expression of miR-370.
