Purpose:Minimal data exist on brain injury in patients with exertional heatstroke(EHS)in developing country.In this study,we explored the risk factors for brain injury induced by EHS 90-day after onset.Methods:A retrospective cohort study of patients with EHS was conducted in the intensive care unit of the General Hospital of Southern Theater Command of PLA in China from April 2014 to June 2019.Patients were divided into non-brain injury(fully recovered)and brain injury groups(comprising deceased patients or those with neurological sequelae).The brain injury group was further subdivided into a death group and a sequela group for detailed analysis.General information,neurological performance and information on important organ injuries in the acute stage were recorded and analysed.Multivariable logistic regression was used to identify risk factors for brain injury after EHS and mortality risk factors for brain injury,and Kaplan-Meier survival curve was used to evaluate the effect of the neurological dysfunction on survival.Results:Out of the 147 EHS patients,117 were enrolled,of which 96(82.1%)recovered,13(11.1%)died,and 8(6.8%)experienced neurological sequelae.Statistically significant differences were found between non-brain injury and brain injury groups in age,hypotension,duration of consciousness disorders,time to drop core body temperature below 38.5℃,lymphocyte counts,platelet counts,procalcitonin,alanine aminotransferase,aspartate aminotransferase,creatinine,cystatin C,coagulation parameters,international normalized ratio,acute physiology and chronic health evaluation II scores,sequential organ failure assessment(SOFA)scores,and Glasgow coma scale scores(all p<0.05).Multivariate logistic regression showed that age(OR=1.090,95%CI:1.02-1.17,p=0.008),time to drop core temperature(OR=8.223,95%CI:2.30-29.40,p=0.001),and SOFA scores(OR=1.676,95%CI:1.29-2.18,p<0.001)are independent risk factors for brain injury induced by EHS.The Kaplan-Meier curves suggest significantly prolonged survival(p<0.001)in patients with

Monogenic disorders refer to a group of human diseases caused by mutations in single genes. While disease-modifying therapies have offered some relief from symptoms and delayed progression for some monogenic diseases, most of these diseases still lack effective treatments. In recent decades, gene therapy has emerged as a promising therapeutic strategy for genetic disorders. Researchers have developed various gene manipulation tools and gene delivery systems to treat monogenic diseases. Despite this progress, concerns about inefficient delivery, persistent expression, immunogenicity, toxicity, capacity limitation, genomic integration, and limited tissue specificity still need to be addressed. This review gives an overview of commonly used gene therapy and delivery tools, along with the challenges they face and potential strategies to counter them.

BACKGROUND Traditional treatments for pancreatic cancer(PC)are inadequate.Photodynamic therapy(PDT)is non-invasive,and proven safe to kill cancer cells,including PC.However,the mitochondrial concentration of the photosensitizer,such as verteporfin,is key.AIM To investigate the distribution of fluorescence of verteporfin in PC cells treated with antitumor drugs,post-PDT.METHODS Workable survival rates of PC cells(AsPC-1,BxPC-3)were determined with chemotherapy[doxorubicin(DOX)and gemcitabine(GEM)]and non-chemotherapy[sirolimus(SRL)and cetuximab(CTX)]drugs in vitro,with or without verteporfin,as measured via MTT,flow cytometry,and laser confocal microscopy.Reduced cell proliferation was associated with GEM that was more enduring compared with DOX.Confocal laser microscopy allowed observation of GEM-and verteporfin-treated PC cells co-stained with 4’,6-diamidino-2-phenylindole and MitoTracker Green to differentiate living and dead cells and subcellular localization of verteporfin,respectively.RESULTS Cell survival significantly dropped upon exposure to either chemotherapy drug,but not to SRL or CTX.Both cell lines responded similarly to GEM.The intensity of fluorescence was associated with the concentration of verteporfin.Additional experiments using GEM showed that survival rates of the PC cells treated with 10μmol/L verteporfin(but not less)were significantly lower relative to nil verte-porfin.Living and dead stained cells treated with GEM were distinguishable.After GEM treatment,verteporfin was observed primarily in the mitochondria.CONCLUSION Verteporfin was observed in living cells.In GEM-treated human PC cells,verteporfin was particularly prevalent in the mitochondria.This study supports further study of PDT for the treatment of PC after neoadjuvant chemotherapy.

Background Environmental factors may contribute to short sleep duration and irregular bedtime in children.Neighborhood factors and children's sleep duration and bedtime regularity remain a less investigated area.The aim of this study was to investigate the national and state-level proportions of children with short sleep duration and irregular bedtime and their neighborhood predictors.Methods A total of 67,598 children whose parents completed the National Survey of Children's Health in 2019-2020 were included in the analysis.Survey-weighted Poisson regression was used to explore the neighborhood predictors of children's short sleep duration and irregular bedtime.Results The prevalence of short sleep duration and irregular bedtime among children in the United States(US)was 34.6%[95%confidence interval(CI)=33.8%-35.4%]and 16.4%(95%CI=15.6%-17.2%)in 2019-2020,respectively.Safe neighborhoods,supportive neighborhoods,and neighborhoods with amenities were found to be protective factors against children's short sleep duration,with risk ratios ranging between 0.92 and 0.94,P<0.05.Neighborhoods with detracting elements were associated with an increased risk of short sleep duration[risk ratio(RR)=1.06,95%CI=1.00-1.12]and irregular bedtime(RR=1.15,95%CI=1.03-1.28).Child race/ethnicity moderated the relationship between neighborhood with amenities and short sleepduration.Conclusions Insufficient sleep duration and irregular bedtime were highly prevalent among US children.A favorable neighborhood environment can decrease children's risk of short sleep duration and irregular bedtime.Improving the neighborhood environment has implications for children's sleep health,especially for children from minority racial/ethnic groups.

Impaired brain glucose metabolism is an early indicator of Alzheimer’s disease(AD);however,the fundamental mechanism is unknown.In this study,we found a substantial decline in isocitrate dehydrogenase 3β(IDH3β)levels,a critical tricarboxylic acid cycle enzyme,in AD patients and AD-transgenic mice’s brains.Further investigations demonstrated that the knockdown of IDH3βinduced oxidation-phosphorylation uncoupling,leading to reduced energy metabolism and lactate accumulation.The resulting increased lactate,a source of lactyl,was found to promote histone lactylation,thereby enhancing the expression of paired-box gene 6(PAX6).As an inhibitory transcription factor of IDH3β,the elevated PAX6 in turn inhibited the expression of IDH3β,leading to tau hyperphosphorylation,synapse impairment,and learning and memory deficits resembling those seen in AD.In AD-transgenic mice,upregulating IDH3βand downregulating PAX6 were found to improve cognitive functioning and reverse AD-like pathologies.Collectively,our data suggest that impaired oxidative phosphorylation accelerates AD progression via a positive feedback inhibition loop of IDH3β-lactate-PAX6-IDH3β.Breaking this loop by upregulating IDH3βor downregulating PAX6 attenuates AD neurodegeneration and cognitive impairments.

Characteristics and main controlling factors of helium resources in the main petroliferous basins of the North China Craton

Acta Oceanologica Sinica 2024年第2期43卷 23-33页

At present, the main controlling factors of helium accumulation is one of the key scientific problems restricting the exploration and development of helium reservoir. In this paper, based on the calculation results of He generation rate and the geochemical characteristics of the produced gas, both the similarities and differences between natural gas and He resources in the Bohai Bay, Ordos and the surrounding Songliao Basin are compared and analyzed, discussing the main controlling factors of helium resources in the three main petroliferous basins of the North China Craton. It is found that the three basins of Bohai Bay, Ordos and Songliao have similar characteristics of source rocks, reservoirs and cap rocks, that's why their methane resource characteristics are essentially the same. The calculated ~4He generation per cubic metamorphic crystalline basement in the three basins is roughly equivalent, which is consistent with the measured He resources, and it is believed that the ~4He of radiogenic from the crust is the main factor controlling the overall He accumulation in the three basins;there is almost no contribution of the mantle-derived CH_4, which suggests that the transport and uplift of mantle-derived ~3He carried by the present-day magmatic activities along the deep-large faults is not the main reason for the mantle-derived ~3He mixing in the basins. Combined with the results of regional volcanic and geophysical studies,it is concluded that under the background of the destruction of North China Craton, magma intrusion carried a large amount of mantle-derived material and formed basic volcanic rocks in the Bohai Bay Basin and Songliao Basin, which replenished mantle-derived ~3He for the interior of the basins, and that strong seismic activities in and around the basins also promoted the upward migration of mantle source ~3He. This study suggests that the tectonic zone with dense volcanic rocks in the Cenozoic era and a high incidence of historical strong earthquakes history may be a potential area for hel

Predator-prey encounters:deciphering the robbery relationship between highwayman flies and their ant victims

Examples of predator–prey interactions in which flies rob ants are uncommon.To date,this behavior has only been recorded in the genus Bengalia Robineau-Desvoidy(Bengaliinae,Diptera,Calliphoridae).These predatory flies ambush ants,and rob them of the food or offspring that they are carrying.However,because of the rarity of this behavior,the reasons and consequences(evolutionary advantages)are unknown,and indeed,the behavior has been sometimes considered anecdotal.In this study,we employed field investigations and behavioral analyses to investigate whether the sex of the fly Bengalia varicolor,or the weight and quality of the food carried by Pheidole nodus ants influenced fly–ant interactions in their natural habitats.We show that food weight and quality influenced the behavior of B.varicolor independent of the fly’s sex.Robbing behavior by the flies was more successful when the food robbed was of high-quality and light in weight.Furthermore,the weight of the food robbed modulated the escape distance the flies could carry it.This then may affect the food quality and weight transported by the ants.This is a novel example of deciphering the relationship between highwayman flies and their ant victims.Given the widespread distribution of Bengalia flies,we suggest that such interspecific predator–prey encounters may shape the robbery interactions and the carrying behavior of further ant species in nature.

Objective:To investigate the effects of Pien Tze Huang(PZH) on the migration and invasion of HCC cells and underlying molecular mechanism.Methods:Cell counting kit-8(CCK-8) was applied to evaluate the cell viabilities of SMMC-7721,SK-Hep-1,C3A and HL-7702(6 × 10^(3)cells/well) co-incubated with different concentrations of PZH(0,0.2,0.4,0.6,0.8 mg/mL) for 24 h.Transwell,wound healing assay,CCK-8and Annexin V-FITC/PI staining were conducted to investigate the effects of PZH on the migration,invasion,proliferation and apoptosis of SK-Hep-1 and SMMC-7721 cells(650 μg/mL for SK-Hep-1 cells and 330 μg/mL for SMMC-7721 cells),respectively.In vivo,lung metastasis mouse model constructed by tail vein injection of HCC cells was used for evaluating the anti-metastasis function of PZH.SK-Hep-1 cells(10^(6)cells/200 μL per mice) were injected into B-NDG mice via tail vein.Totally 8 mice were randomly divided into PZH and control groups,4 mice in each group.After 2-d inoculation,mice in the PZH group were administered with PZH(250 mg/kg,daily) and mice in the control group received only vehicle(PBS) from the 2nd day after xenograft to day 17.Transcriptome analysis based on RNA-seq was subsequently used for deciphering anti-tumor mechanism of PZH.Quantitative real-time polymerase chain reaction(qRT-PCR) and Western blot were applied to verify RNA-seq results.Luciferase reporter assay was performed to examine the transcriptional activity of yes-associated protein(YAP).Results:PZH treatment significantly inhibited the migration,invasion,proliferation and promoted the apoptosis of HCC cells in vitro and in vivo(P<0.01).Transcriptome analysis indicated that Hippo signaling pathway was associated with anti-metastasis function of PZH.Mechanical study showed PZH significantly inhibited the expressions of platelet derived growth factor receptor beta(PDGFRB),YAP,connective tissue growth factor(CCN2),N-cadherin,vimentin and matrix metallopeptidase 2(MMP2,P<0.01).Meanwhile,the phosphorylation of YAP was also enhanced by PZH treatment in v
