Objective To investigate the predictive value of serum interleukin-17(IL-17)combined with eotaxin-3 for poor prognosis in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods A total of 213 patients with AECOPD admitted to Beijing Municipal Armed Police Force Hospital from May 2018 to July 2023 were selected as the disease group.According to the prognosis of patients,they were divided into good prognosis group(133 cases)and poor prognosis group(80 cases).At the same time,205 physical examination healthy people in Beijing Municipal Armed Police Force Hospital were selected as the healthy group.The serum levels of IL-17 and eotaxin-3 were detected by enzyme-linked immu-nosorbent assay.The clinical data of poor prognosis group and good prognosis group were compared.Pearson correlation analysis was used to analyze the correlation between serum IL-17 level and eotaxin-3 in AECOPD patients.Multivariate Logistic regression analysis was used to analyze the related factors affecting the progno-sis of AECOPD patients.The receiver operating characteristic(ROC)curve was used to evaluate the predic-tive value of serum IL-17 and eotaxin-3 levels for the prognosis of AECOPD patients.Results Compared with the healthy group,the serum levels of IL-17 and eotaxin-3 were increased in the disease group(P<0.05).Compared with the good prognosis group,the poor prognosis group had significant increases in serum IL-17 and eotaxin-3 levels(P<0.05).Serum IL-17 level was positively correlated with eotaxin-3 in AECOPD pa-tients(r=0.537,P<0.001).There were significant differences in Global Initiative for Chronic Obstructive Lung Disease(GOLD)grade,blood oxygen partial pressure(PaO2)and carbon dioxide partial pressure(PaCO2)between the poor prognosis group and the good prognosis group(P<0.05).GOLD grade,PaCO2,serum IL-17 and eotaxin-3 levels were risk factors for poor prognosis in patients with AECOPD(P<0.05),and PaO2 was a protective factor for poor prognosis in patients with AECOPD(P<0.05).The area under the curve of serum IL-17 and eotaxin-3 combined to predict the prognosis of AECOPD patients was 0.885,the sensitivity was 80.00%,and the specificity was 83.46%,which was better than that of IL-17 and eotaxin-3 a-lone(Zcombiation-IL-17=4.045,P<0.001,Zcombiation-eotaxin-3=3.254,P=0.001).Conclusion The serum levels of IL-17 and eotaxin-3 are increased in AECOPD patients.The combination of IL-17 and eotaxin-3 has predictive value for the prognosis of AECOPD patients.

Lymphoma is a highly heterogeneous malignancy characterized by complex molecular regulatory mechanisms that result in significant differences in aggressiveness and prognosis across its subtypes.Gene copy number alteration(CNA)analysis,an emerging technology,has become a pivotal tool in the precision re-search and management of lymphoma.By detecting DNA deletions,amplifications,and chromosomal copy number changes,CNA analysis addresses the limitations of traditional cytogenetic techniques,enhances the ac-curacy of subtype classification,and aids in evaluating tumor heterogeneity and disease progression.This re-view provides a comprehensive summary of CNA detection methods and their applications in lymphoma,with a focus on recent advancements in the field.It offers a comparative analysis of CNA detection techniques and discusses their role in precision diagnosis,subtype classification,monitoring disease progression,predicting therapeutic resistance,and assessing prognosis.Additionally,the review explores the potential applications of CNA analysis in uncovering molecular regulatory mechanisms,optimizing therapeutic strategies,and impro-ving patient survival outcomes.

ObjectiveAutism spectrum disorder (ASD) is a neurodevelopmental condition characterized by difficulties with communication and social interaction, restricted and repetitive behaviors. Previous studies have indicated that individuals with ASD exhibit early and lifelong attention deficits, which are closely related to the core symptoms of ASD. Basic visual attention processes may provide a critical foundation for their social communication and interaction abilities. Therefore, this study explores the behavior of children with ASD in capturing attention to changes in topological properties. MethodsOur study recruited twenty-seven ASD children diagnosed by professional clinicians according to DSM-5 and twenty-eight typically developing (TD) age-matched controls. In an attention capture task, we recorded the saccadic behaviors of children with ASD and TD in response to topological change (TC) and non-topological change (nTC) stimuli. Saccadic reaction time (SRT), visual search time (VS), and first fixation dwell time (FFDT) were used as indicators of attentional bias. Pearson correlation tests between the clinical assessment scales and attentional bias were conducted. ResultsThis study found that TD children had significantly faster SRT (P<0.05) and VS (P<0.05) for the TC stimuli compared to the nTC stimuli, while the children with ASD did not exhibit significant differences in either measure (P>0.05). Additionally, ASD children demonstrated significantly less attention towards the TC targets (measured by FFDT), in comparison to TD children (P<0.05). Furthermore, ASD children exhibited a significant negative linear correlation between their attentional bias (measured by VS) and their scores on the compulsive subscale (P<0.05). ConclusionThe results suggest that children with ASD have difficulty shifting their attention to objects with topological changes during change detection. This atypical attention may affect the child’s cognitive and behavioral development, thereby impacting their social communication and interaction. In sum, our findings indicate that difficulties in attentional capture by TC may be a key feature of ASD.

Forsythia suspensa is a traditional Chinese medicine and a commonly used landscaping plant. Its dried fruit is used in medicine for its functions of clearing heat, removing toxins, reducing swelling, dissipating masses, and dispersing wind and heat. It possesses extremely high medicinal and economic value. However, the genetic differentiation and diversity of its wild populations remain unclear. In this study, chloroplast genome sequences were obtained from 15 wild individuals of F. suspensa using high-throughput sequencing technology. The sequence characteristics and intraspecific variations were analyzed. The results were as follows:(1) The full length of the F. suspensa chloroplast genome ranged from 156 184 to 156 479 bp, comprising a large single-copy region, a small single-copy region, and two inverted repeat regions. The chloroplast genome encoded a total of 132 genes, including 87 protein-coding genes, 37 tRNA genes, and 8 rRNA genes.(2) A total of 166-174 SSR loci, 792 SNV loci, and 63 InDel loci were identified in the F. suspensa chloroplast genome, indicating considerable genetic variation among individuals.(3) Population structure analysis revealed that F. suspensa could be divided into five or six groups. Both the population structure analysis and phylogenetic reconstruction results indicated significant genetic variation within the wild populations of F. suspensa, with no obvious correlation between intraspecific genetic differentiation and geographical distribution. This study provides new insights into the genetic diversity and differentiation within F. suspensa species and offers additional references for the conservation of species diversity and the utilization of germplasm resources in wild F. suspensa.

This study aims to explore the effects and action mechanisms of the active ingredients in Buyang Huanwu Decoction(BYHWD), namely tetramethylpyrazine(TMP) and hydroxy-safflor yellow A(HSYA), on oxygen-glucose deprivation/reglucose-reoxygenation(OGD/R)-induced inflammation and oxidative stress of microglia(MG). Network pharmacology was used to screen the effective monomer ingredients of BYHWD and determine the safe concentration range for each component. Inflammation and oxidative stress models were established to further screen the best ingredient combination and optimal concentration ratio with the most effective anti-inflammatory and antioxidant effects. OGD/R BV2 cell models were constructed, and BV2 cells in the logarithmic growth phase were divided into a normal group, a model group, an HSYA group, a TMP group, and an HSYA + TMP group. Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of inflammatory cytokines such as interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), and interleukin-6(IL-6). Oxidative stress markers, including superoxide dismutase(SOD), nitric oxide(NO), and malondialdehyde(MDA), were also measured. Western blot was used to analyze the protein expression of both inflammation-related pathway [Toll-like receptor 4(TLR4)/nuclear factor-kappa B(NF-κB)] and oxidative stress-related pathway [nuclear factor erythroid 2-related factor 2(Nrf2)/heme oxygenase-1(HO-1)]. Immunofluorescence was used to assess the expression of proteins such as inducible nitric oxide synthase(iNOS) and arginase-1(Arg-1). The most effective ingredients for anti-inflammatory and antioxidant effects in BYHWD were TMP and HSYA. Compared to the normal group, the model group showed significantly increased levels of IL-1β, TNF-α, IL-6, NO, and MDA, along with significantly higher protein expression of NF-κB, TLR4, Nrf2, and HO-1 and significantly lower SOD levels. The differences between the two groups were statistically significant. Compared to the model group, both the HSYA group and the TMP group showed significantly reduced levels of IL-1β, TNF-α, IL-6, NO, and MDA, lower expression of NF-κB and TLR4 proteins, higher levels of SOD, and significantly increased protein expression of Nrf2 and HO-1. Additionally, the expression of the M1-type MG marker iNOS was significantly reduced, while the expression of the M2-type MG marker Arg-1 was significantly increased. The results of the HSYA group and the TMP group had statistically significant differences from those of the model group. Compared to the HSYA group and the TMP group, the HSYA + TMP group showed further significant reductions in IL-1β, TNF-α, IL-6, NO, and MDA levels, along with significant reductions in NF-κB and TLR4 protein expression, an increase in SOD levels, and elevated Nrf2 and HO-1 protein expression. Additionally, the expression of the M1-type MG marker iNOS was reduced, while the M2-type MG marker Arg-1 expression increased significantly in the HSYA + TMP group compared to the TMP or HSYA group. The differences in the results were statistically significant between the HSYA + TMP group and the TMP or HSYA group. The findings indicated that the combined use of HSYA and TMP, the active ingredients of BYHWD, can effectively inhibit OGD/R-induced inflammation and oxidative stress of MG, showing superior effects compared to the individual use of either component.

Objective:To investigate the efficacy of enteral nutrition combined with trocar puncture with a sump drain in the treatment of Crohn's disease(CD)complicated by intra-abdominal abscess.Methods:A descriptive case series study was conducted.Clinical data of CD patients with intra-abdominal abscess who received enteral nutrition and trocar puncture with a sump drain at the Intestinal Fistula and Intra-abdominal Infection Center of Nanjing BenQ Hospital between June 2018 and December 2022 were retrospectively collected.Laboratory parameters,including white blood cell(WBC)count,C-reactive protein(CRP),and procalcitonin(PCT),were recorded at baseline(pre-puncture)and on days 1,3,and 7 post-puncture.Changes in clinical indicators before and after intervention were compared.Results:All 19 CD patients with intra-abdominal abscess successfully underwent CT-guided trocar puncture with a sump drain,with fistulography confirming the presence of intestinal fistula.No post-procedural complications,including puncture site infection,new-onset intestinal fistula or intra-abdominal hemorrhage,were observed.The median treatment duration was 58.3 days(range:14～300 days).10 patients achieved spontaneous healing while 9 eventually underwent surgical intervention for unresolved fistulas.Post-puncture WBC levels decreased significantly on days 1,3,and 7 compared to baseline(P<0.05).Serum CRP levels increased markedly on day 1 post-puncture(P<0.05)but declined significantly by days 3 and 7(P<0.05).No statistically significant difference was observed in serum procalcitonin levels before and after puncture(P>0.05).Conclusion:The combination of enteral nutrition and trocar puncture with a sump drain is safe,feasible,and effective for managing CD complicated by intra-abdominal abscess.

Objective:This study aims to explore the ability of three assessment tools,namely mPG-SGA,PG-SGA,and GLIM,to evaluate malnutrition in patients with head/neck tumors undergoing radiotherapy.Additionally,it intends to investigate the correlation between mPG-SGA and calf circumference,grip strength,as well as traditional laboratory indicators in assessing malnutrition in this patient population.Methods:Prospectively,patients with head/neck tumors undergoing radiotherapy in West China Hospital,Sichuan University from January 1,2025 to March 20,2025 were selected as the research subjects.Baseline data and traditional nutritional indicators of the patients were collected,and malnutrition assessment was conducted using three tools:mPG-SGA,PG-SGA,and GLIM.Spearman correlation coefficient was used for analysis to explore the correlation between mPG-SGA scores and traditional nutritional indicators.Results:A total of 106 patients were initially included in this study,with 6 cases excluded,resulting in 100 eligible head and neck tumor patients.The average age of the enrolled patients was(51.62±11.97)years,among whom 74 were male(74%).The incidence rates of malnutrition assessed by mPG-SGA,PG-SGA,and GLIM were 41%,45%,and 23%,respectively.With PG-SGA as the gold standard reference,the sensitivity of mPG-SGA and GLIM in detecting malnutrition was 100.00%and 28.89%,respectively,and the specificity was 93.22%and 81.82%,respectively,with AUC values of 0.956 and 0.554.Results of correlation analysis showed that left calf circumference,right calf circumference,dominant hand grip strength,non-dominant hand grip strength,hemoglobin,and red blood cells were positively correlated with mPG-SGA[correlation coefficients were 0.307(P=0.002),0.294(P=0.003),0.395(P<0.001),0.360(P<0.001),0.226(P=0.028),and 0.267(P=0.009),respectively].Conclusion:mPG-SGA exhibited comparable diagnostic efficacy to PG-SGA and GLIM for malnutrition assessment in head and neck cancer patients undergoing radiotherapy,while offering simplified operational procedures.This tool shows potential as a rapid nutritional evaluation alternative,though multicenter validation across various cancer types remains necessary.

Endosomes are characterized by the presence of various phosphoinositides that are essential for defining the membrane properties. However, the interplay between endosomal phosphoinositides metabolism and innate immunity is yet to be fully understood. Here, our findings highlight the evolutionary continuity of RAB-10/Rab10's involvement in regulating innate immunity. Upon infection of Caenorhabditis elegans with Pseudomonas aeruginosa, an increase in RAB-10 activity was observed in the intestine. Conversely, when RAB-10 was absent, the intestinal diacylglycerols (DAGs) decreased, and the animal's response to the pathogen was impaired. Further research revealed that UNC-16/JIP3 acts as an RAB-10 effector, facilitating the recruitment of phospholipase EGL-8 to endosomes. This leads to a decrease in endosomal phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2) and an elevation of DAGs, as well as the activation of the PMK-1/p38 MAPK innate immune pathway. It is noteworthy that the dimerization of UNC-16 is a prerequisite for its interaction with RAB-10(GTP) and the recruitment of EGL-8. Moreover, we ascertained that the rise in RAB-10 activity, due to infection, was attributed to the augmented expression of LET-413/Erbin, and the nuclear receptor NHR-25/NR5A1/2 was determined to be indispensable for this increase. Hence, this study illuminates the significance of endosomal PI(4,5)P2 catabolism in boosting innate immunity and outlines an NHR-25-mediated mechanism for pathogen detection in intestinal epithelia.
