Tebuconazole exposure has been described as an increasing hazard to human health.An increasing number of recent studies have shown a positive association between tebuconazole exposure and cardiovascular disease risk,which is characterized by the reduction of adenosine triphosphate(ATP)synthesis.However,researches on the damage of tebuconazole exposure to energy metabolism and the related molecular mechanisms are limited.In the present study,male C57BL/6 mice were treated with tebuconazole at different low concentrations for 4 weeks.The results indicated that tebuconazole could accumulate in the heart and further induce the decrease of ATP content in the mouse heart.Importantly,tebuconazole induced an obvious shift in substrate utilization of fatty acid and glucose by disrupting their corresponding transporters(GLUT1,GLUT4,CD36,FABP3 and FATP1)expression,and significantly repressed the expression of mitochondrial biogenesis(Gabpa and Tfam)and oxidative phosphorylation(CS,Ndufa4,Sdhb,Cox5a and Atp5b)related genes in a dosedependent manner.Further investigation revealed that these alterations were related to the IRS1/AKT and PPARγ/RXRαpathways.These findings contribute to a better understanding of triazole fungicide-induced cardiovascular disease by revealing the key indicators associated with this phenomenon.

An experiment was conducted to determine the standardized ileal digestible (SID) calcium requirement of fast-growing broilers from hatch to d 14 post-hatch.Ross 308 (n=360) male broilers were obtained on day of hatch and allocated to 1 of 5 treatments in battery cages.There were 6 birds per cage and 12 pens per treatment.Four treatments were formulated to contain 0.60%,0.46%,0.32% or 0.18% SID Ca.The final treatment was formulated using total Ca to meet or exceed all nutrient requirements,including 0.90% total Ca and 0.49% non-phytate P (nPP),using the same ingredients.This treatment was the reference diet for comparison and validation of the SID Ca diets.Birds and feed were weighed at placement and on d 14.Tibias and ileal contents were obtained on d 14 and excreta was collected per pen and pooled on d 14.Data were analyzed using JMP Pro and requirements were estimated using 3different non-linear regression models.Increasing the SID Ca content in the diet from 0.18% to 0.60% improved (quadratic,P<0.05) body weight gain and mortality corrected feed conversion ratio (mFCR).The estimated SID Ca requirement to optimize gain or m FCR was between 0.39% and 0.52%.Tibia ash percent and weight increased (quadratic,P<0.05) as SID Ca content in the diet increased and the estimated SID Ca requirement was between 0.32% and 0.58%.Phosphorus utilization was improved in birds fed diets formulated using SID Ca compared with birds fed the reference diet.In conclusion,the SID Ca requirement of fast-growing broilers from hatch to d 14 was estimated between 0.534% and 0.398% when quadratic,straight-broken line,or quadratic-broken line regressions were used.These results agree with previously published data evaluating the SID Ca requirement of fast-growth broilers from hatch to d 10.

5q spinal muscular atrophy (5qSMA) is an autosomal recessive neuromuscular disorder caused by the lack of the survival motor neuron (SMN) protein encoded by the SMN1 gene, located at 5q11.2-q13.3.[1] The incidence is 1/10,000-1/6000 live births, and the mutation carrier rate in China is 1/42.[1] Spinal muscular atrophy (SMA) is mainly divided into four subtypes: SMA type I, II, III, and IV, based on the motor milestones ever achieved. Types I-III occur in children,[1] which often result in progressive muscular atrophy and weakness as well as multi-system dysfunction, including nutritional and metabolic issues.[2] Children with SMA may have hidden nutritional and lipid imbalances, despite normal body appearance and anthropometric measurements, making it difficult to detect early and intervene. Fewer studies have elucidated both the nutritional status and lipid metabolism in SMA patients,[2] especially in Asia, which may have some of the highest numbers of SMA patients in the world. To inform the development of targeted nutritional management strategies, this study aimed to investigate the nutritional status and serum lipid profile characteristics in children with SMA, based on a hospital-based case-control study in China. This study was approved by the Ethics Committee of Children's Hospital of Zhejiang University School of Medicine (No. 2019-IRB-171). Written informed consent was obtained from all the patients and their legal guardians.

Immunogenic death is a form of programmed cell death that is common in the development and progression of cancer.However,its impact on tumor progression differs depending on the location of the tumor.Meanwhile,it also plays an important role in antitumor immunity because the process of immunogenic death can release substances that activate immunity.1 Therefore,in this study,the key mechanism of mediating immunogenic death in hepatocellular carcinoma(HCC)was found from the excavation of the immunogenic death characteristics of pan-cancer and the in-depth investigation of its effects on different tumor types(Fig.1A).

Background Macrophages are involved in various immune inflammatory disease conditions.This study aimed to investigate the role and mechanism of macrophages in regulating acute intestinal injury in neonatal necrotizing enterocolitis(NEC).Methods CD68,nucleotide-binding oligomerization domain,leucine-rich repeat,and pyrin domain-containing 3(NLRP3),cysteine aspartate-specific protease-1(caspase-1),and interleukin-1β(IL-1β)in paraffin sections of intestinal tissues from NEC and control patients were detected with immunohistochemistry,immunofluorescence,and western blot.Hypertonic pet milk,hypoxia and cold stimulation were used to establish a mouse(wild type and Nlrp3^(-/-))model of NEC.The mouse macrophage(RAW 264.7)and rat intestinal epithelial cell-6 lines were also cultured followed by various treatments.Macrophages,intestinal epithelial cell injuries,and IL-1β release were determined.Results Compared to the gut“healthy”patients,the intestinal lamina propria of NEC patients had high macrophage infiltration and high NLRP3,caspase-1,and IL-1β levels.Furthermore,in vivo,the survival rate of Nlrp3^(-/-)NEC mice was dramatically improved,the proportion of intestinal macrophages was reduced,and intestinal injury was decreased compared to those of wild-type NEC mice.NLRP3,caspase-1,and IL-1β derived from macrophages or supernatant from cocultures of macrophages and intestinal epithelial cells also caused intestinal epithelial cell injuries.Conclusions Macrophage activation may be essential for NEC development.NLRP3/caspase-1/IL-1β cellular signals derived from macrophages may be the underlying mechanism of NEC development,and all these may be therapeutic targets for developing treatments for NEC.

Background Surgery plays an important role in the treatment of neuroblastoma.Perioperative complications may impact the course of neuroblastoma treatment.To date,comprehensive analyses of complications and risk factors have been lacking.Methods Patients with retroperitoneal neuroblastoma undergoing tumor resection were retrospectively analyzed between 2014 and 2021.The data collected included clinical characteristics,operative details,operative complications and postopera-tive outcomes.Risk factors for perioperative complications of retroperitoneal neuroblastoma were analyzed.Results A total of 571 patients were enrolled in this study.Perioperative complications were observed in 255(44.7%)patients.Lymphatic leakage(28.4%),diarrhea(13.5%),and injury(vascular,nerve and organ;7.5%)were the most frequent compli-cations.There were three operation-related deaths(0.53%):massive hemorrhage(n=1),biliary tract perforation(n=1)and intestinal necrosis(n=1).The presence of image-defined risk factors(IDRFs)[odds ratio(OR)=2.09,P<0.01],high stage of the International Neuroblastoma Risk Group staging system(INRGSS)(OR=0.454,P=0.04),retroperitoneal lymph node metastasis(OR=2.433,P=0.026),superior mesenteric artery encasement(OR=3.346,P=0.003),and inferior mesenteric artery encasement(OR=2.218,P=0.019)were identified as independent risk factors for perioperative complications.Conclusions Despite the high incidence of perioperative complications,the associated mortality rate was quite low.Perio-perative complications of retroperitoneal neuroblastoma were associated with IDRFs,INRGSS,retroperitoneal lymph node metastasis and vascular encasement.Patients with high-risk factors should receive more serious attention during surgery but should not discourage the determination to pursue total resection of neuroblastoma.

Over the past decade, mitochondrial dysfunction has been investigated as a key contributor to acute and chronic kidney disease. However, the precise molecular mechanisms linking mitochondrial damage to kidney disease remain elusive. The recent insights into the cyclic guanosine monophosphate-adenosine monophosphate (GMP-AMP) synthetase (cGAS)-stimulator of interferon gene (STING) signaling pathway have revealed its involvement in many renal diseases. One of these findings is that mitochondrial DNA (mtDNA) induces inflammatory responses via the cGAS-STING pathway. Herein, we provide an overview of the mechanisms underlying mtDNA release following mitochondrial damage, focusing specifically on the association between mtDNA release-activated cGAS-STING signaling and the development of kidney diseases. Furthermore, we summarize the latest findings of cGAS-STING signaling pathway in cell, with a particular emphasis on its downstream signaling related to kidney diseases. This review intends to enhance our understanding of the intricate relationship among the cGAS-STING pathway, kidney diseases, and mitochondrial dysfunction.

Background The prevalence of prolonged grief disorder(PGD)and its symptoms among the bereaved population in China vary considerably.Aims This meta-analysis aims to estimate the prevalence of PGD and its symptoms among bereaved individuals in China.Methods We conducted a literature search in major Chinese and English databases from their inception to 4 October 2023,for cross-sectional studies on the prevalence of PGD or its symptoms in bereaved Chinese individuals.The risk of bias of the included studies and certainty of the evidence were assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data(‘JBI checklist’)and the Grading of Recommendations,Assessment,Development and Evaluations(GRADE),respectively.The‘metaprop’package in R V.4.1.2 was used to synthesise the prevalence.Results A total of 28 studies involving 10994 bereaved individuals were included in the analysis,with JBI checklist scores between 3 and 7.The combined prevalence(95%confidence interval)of PGD and its symptoms was 8.9%(4.2%to 17.6%)and 32.4%(18.2%to 50.8%),respectively.PGD and its symptoms were most prevalent among those who had lost their only child(22.7%)and those bereaved by earthquakes(80.4%),respectively.The GRADE system assigned a very low certainty level to the evidence for the pooled prevalence of PGD and its symptoms.Conclusions The pooled prevalence of PGD and its symptoms indicate a potential high need for grief counselling services among bereaved individuals in China.This need is particularly pronounced in those who have lost their only child and those bereaved due to earthquakes.Further methodologically rigorous studies are needed to provide more accurate prevalence estimates.PROSPERO registration number CRD42023432553.
