Objective:To explore the association between childhood trauma and prefrontal cortex functional networks in early adulthood using functional near-infrared spectroscopy(fNIRS).Methods:Twenty-eight individu-als with childhood trauma comprised the trauma group,while 32 without trauma formed the control group.The Childhood Trauma Questionnaire(CTQ)assessed abuse and neglect,the Ruminative Responses Scale(RRS)meas-ured repetitive thinking about negative events,and the Iowa Gambling Task(IGT)evaluated decision-making tend-encies.fNIRS data collected during the IGT were used to calculate degree centrality(DC),betweenness centrality(BC),and local efficiency(LE)in prefrontal networks.Mediation analysis explored relationships among childhood trauma,brain function(DC,BC,LE),and ruminative thinking.Results:Compared to controls,the trauma group had decreased DC in bilateral dorsolateral prefrontal cortices,increased DC,BC,and LE in the right inferior frontal gy-rus,and elevated LE in the bilateral frontal poles.BC and LE in the right inferior frontal gyrus partially mediated the relationship between CTQ sexual abuse and RRS scores(48.57％and 41.43％,respectively).Conclusion:Child-hood trauma is significantly associated with changes in prefrontal network properties in early adulthood.Sexual a-buse,in particular,may influence emotional regulation and cognitive functions by altering the network attributes of the right inferior frontal gyrus.

Objective To analyze the disease burden of early-onset colorectal cancer (EOCRC) at the global, regional, and national levels from 1990 to 2021, and to predict the disease burden trend from 2022 to 2026. Methods Based on the Global Burden of Disease (GBD) database, the incidence, mortality, and disability-adjusted life year (DALY) rate of EOCRC across 204 countries and regions from 1990 to 2021 were obtained. The time trends of these indicators were assessed by calculating the estimated annual percentage change (EAPC), and the contributions of ten risk factors to the EOCRC burden were analyzed. The autoregressive integrated moving average (ARIMA) model was used to predict the disease burden from 2022 to 2026. Results From 1990 to 2021, the number of new global EOCRC cases increased from 107 310 to 211 890, with the incidence rising from 3.96 to 5.37 per 100 000 people. In 2021, global EOCRC incidence, mortality, and DALY rate increased with age; males had higher rates than females in terms of incidence, mortality, and DALY rate in all age groups. In 2021, East Asia had the highest number of new cases, deaths, and DALY. From 1990 to 2021, the global EAPC for incidence rate was 0.96%, and death rate was –0.38%. ARIMA model indicated that from 2022 to 2026, the global incidence of EOCRC would continue to rise, while mortality and DALY rate would be expected to decline. Conclusions The disease burden of EOCRC has significantly increased globally from 1990 to 2021, with notable regional, age, and sex differences. By 2026, the mortality and DALY rate of EOCRC will decline, while the incidence is expected to further increase, highlighting the urgency of taking active measures to address the growing trend of EOCRC.

Circular RNA(circRNA),as a kind of non-coding RNA,regulates a variety of biological functions.To explore the effect of circRNA on PEDV replication in the host porcine intestinal epi-thelial cells,this study screened and analyzed the differentially expressed circRNAs by bioinforma-tic software in African Green Monkey renal cells(Vero-E6 cells)infected by porcine epidemic di-arrhea virus(PEDV),the differentially expressed circRNA ssc_circ_PIK3C2A was identified and the secondary structure was analyzed.PCR was used to identify the ssc_circ_PIK3C2A circRNA structure,the model of PEDV-infected IPEC-J2 cells was constructed,the TCID50 test was used to validate the viral titer of PEDV.The expression of circ_PIK3C2A was detected by qRT-PCR in IPEC-J2 infected by PEDV.circ_PIK3C2A qRT-PCR was performed to detect the expression of N gene of PEDV when ssc_circ_PIK3C2A was over-expressed in IPEC-J2 cells.The results showed that ssc_circ_PIK3C2 A is a porcine circular RNA with a typical circular structure,the virus titer of PEDV reached 10-6/mL after PEDV infected IPEC-J2 cells for 48 h,the expression of circ_PIK3C2A increased extremely(P＜0.01)at 6 h after PEDV-infection,with the extension of infec-tion time,its expression gradually decreased,and the expression was the lowest at 24 h,but there was no time-dependent trend.The expression of PEDV N gene decreased significantly when ssc_circ_PIK3C2A was over-expressed in IPEC-J2 cells.In conclusion,when PEDV infects IPEC-J2 cells,the expression of porcine circ_PIK3C2A decreases,and replication of PEDV increases signifi-cantly in IPEC-J2 cells.our result provides a basis for further study of the mechanism of circular RNA on PEDV replication and its physiological activities in host cells in the future.

Glioma is an intracranial tumor with high malignancy and significant heterogeneity.In the treatment,glioma is mainly based on surgery,supplemented by radiotherapy and chemotherapy,its treatment plan and decision-making are closely related to its heterogeneity.MRI habitat analysis is a non-invasive examination method.Its principle is to convert the MRI image information of tumors into mineable feature data and extract them quantitatively,so as to realize the quantitative characterization of the temporal and spatial heterogeneity of tumors,reflect the occurrence and progression of tumors,and reveal the biological differences in pathophysiology and molecular typing within tumors,which is conducive to the customization of individualized treatment plans for patients.At present,habitat analysis has made great progress in predicting tumor classification,evaluating the prognosis of glioma,identifying tumor response after treatment and tumor recurrence,and has shown great potential in promoting molecular diagnosis,individualized immunotherapy and chemotherapy in precision medicine.In this paper,the application of habitat analysis technology in glioma research is reviewed and analyzed.

Objective Advances in synthetic DNA technology have made it much easier to fake human DNA samples.There are literature reports that fake human DNA can be synthesized by different methods and implanted in the field to confuse the investigation or mislead the trial.Therefore,distinguishing authentic human DNA from synthetic DNA and performing individual identification has become a critical scientific challenge.Methods We define a novel composite genetic marker(methylation-microhaplotype)by combining CpG sites stably hypermethylated or hypomethylated in natural human DNA and nearby immediately adjacent microhaplotype sites.A total of 19 locis were obtained according to the screening criteria,and a composite detection system for methylation-microhaplotypes was established using MPS technology.Random volunteer DNA samples were extracted and synthetic DNA samples were prepared based on whole genome amplification techniques.Population DNA samples were analyzed to evaluate forensic parameters and methylation variability of the methylation-microhaplotype markers.Comparative analyses of human and synthetic DNA were conducted to assess the markers'ability to discriminate between the two and to detect/type both components in mixed mixed samples.Results The composite detection system composed of 19 locis demonstrated high individual identification ability,achieving a cumulative individual identification probability of 0.999 999 999 996 86.12 hypermethylated locis and 7 hypomethylated locis had relatively stable methylation levels in 57 human DNA samples.According to the allele methylation rate(Ram)value,the system can effectively identify natural and synthetic DNA samples.Meanwhile,for mixed DNA samples,the presence of human and synthetic DNA samples can be found and genotyped.Conclusion Methylation-microhaplotype genetic markers,which can discover human DNA and synthetic DNA and can detect the presence and genotyping of them from mixed samples,is a potential useful tool for forensic DNA analysis.
