ObjectiveTo establish a geographical origin identification model for Foeniculi Fructus from Haiyuan， providing a new technical reference for the protection of Haiyuan's geo-authentic medicinal materials and its designation as a national geographical indication agricultural product. MethodsSamples of Foeniculi Fructus were collected from eight producing areas， including Minqin （Gansu）， Bozhou （Anhui）， Qingdao （Shandong）， Dezhou （Shandong）， Urumqi （Xinjiang）， Nujiang （Yunnan）， Gutuo （Inner Mongolia）， and Haiyuan （Ningxia）. Gas chromatography-ion mobility spectrometry （GC-IMS） was used to detect the volatile organic compounds （VOCs） in samples from these geographic origins. VOCs were qualitatively analyzed through dual matching with the National Institute of Standards and Technology （NIST） mass spectral database and the IMS drift time database. Using the Reporter module and Gallery Plot visualization tools within the LAV analytical platform， VOC fingerprint profiles characterizing geographic origins were constructed. A non-targeted analytical strategy was adopted， and 97 VOCs detected via GC-IMS were subjected to principal component analysis （PCA） and partial least squares discriminant analysis （PLS-DA） based on their differential distribution patterns to construct an origin identification model for Foeniculi Fructus from Haiyuan region. Key discriminative markers were screened using variable importance in projection （VIP） values greater than 1. ResultsA total of 97 VOCs were identified， including alcohols， aldehydes， ketones， esters， organic acids， terpenoids， ethers， alkenes， and benzenes. The PLS-DA model， based on VOCs data obtained by GC-IMS， effectively distinguished Foeniculi Fructus in Haiyuan region from those of other origins. During cross-validation， the model achieved a prediction parameter （Q²） of 0.976 and a goodness-of-fit parameter （R²） of 0.936， with no overfitting observed in permutation testing. Twelve key flavor markers with VIP > 1 were identified as characteristic indicators of Haiyuan origin. ConclusionA stable and highly predictive origin identification model for Foeniculi Fructus from Haiyuan was successfully established using GC-IMS technology， PLS-DA， and VIP-based marker screening. This model provides a novel technical strategy for accurately distinguishing Foeniculi Fructus in Haiyuan region from other regional varieties and offers new technical support for its protection as a geo-authentic medicinal material and a nationally designated geographical indication agricultural product in China.

OBJECTIVE: To investigate the expression and possible regulatory mechanism of miR-34a in the lung tissue of neonatal rat model of bronchopulmonary dysplasia (BPD) induced by hyperoxia. METHODS: In the study, 80 newborn SD rats were randomly divided into hyperoxia group (FiO₂=60%) and air group (FiO₂=21%) within 2 hours after birth, 40 rats per group. Lung tissue samples of the SD rats in each group were extracted on the 1st, 7th, 14th and 21st days after birth, and the pathological changes of lung tissue were observed under light microscope after HE staining. The number of radial alveolar counts (RAC) and the mean alveolar diameter (MAD) and the thickness of alveolar septal thickness (AST) were measured to evaluate the development of alveoli. Real-time fluorescence quantitative PCR was used to detect the expression of miR-34a, angiopoietin-1 (Ang-1) and tyrosine kinase receptor-2 (Tie-2) in lung tissue of rats in hyperoxia group and air group at different time points. Enzyme-linked immunosorbent assay (ELISA) was used to detect the proteins expression of Ang-1 and Tie-2 in the lung tissues of the two groups at different time points. RESULTS: The weight of rats in the hyperoxia group on the 7th, 14th and 21st days after birth was significantly lower than that in the air group (P all < 0.05). With the prolongation of oxygen exposure, the number of alveoli decreased, the volume increased, the structure simplified, the alveolar cavity enlarged obviously and the alveolar septum thickened in the hyperoxia group. On the 7th, 14th and 21st days after birth, the RAC in the hyperoxia group was significantly lower than that in the air group (P all < 0.05). Compared with the air group, MAD and AST increased significantly on the 7th, 14th and 21st days after birth in the hyperoxia group, and the difference was statistically significant (P all < 0.05). The expression level of miR-34a in lung tissue of hyperoxia group was significantly higher than that of air group on the 7th, 14th and 21st days after birth, and the difference was statistically significant (P all < 0.05). Compared with the air group at the same time point, the expression levels of Ang-1 and Tie-2 mRNA and protein in the hyperoxia group were lower than those in the air group on the 14th and 21st days after birth (P all < 0.05). CONCLUSION The new BPD model of newborn SD rats can be successfully established by continuous exposure to 60% hyperoxia. The expression of miR-34a was up-regulated in the lung tissue of the new BPD model of neonatal rats. MiR-34a may play an important role in the occurrence and development of BPD by regulating Ang-1/Tie-2 signal pathway.

Antibiotic resistance is spreading at a faster rate than new antibiotic agents applied for clinical remedies. It is an urgent need to discover potential compounds to combat multidrug-resistant (MDR) bacteria. Marine fungi offer a promising avenue for mining antibiotic-like molecules with chemical diversity. To discover structurally novel and antibiotic metabolites, we screened the in-house marine fungus genome library and found a fungus Stephanonectria keithii LZD-10-1 containing a non-ribosomal peptide synthetase (NRPS) cluster with 18 modules to synthesize a new subfamily of peptaibols with effective eradication against MDR pathogens. Targeting isolation of the cultured fungus afforded six new peptaibols, which exhibit the ability to kill MDR bacteria by targeting bacterial membrane phospholipids, especially phosphatidylglycerol (PG), leading to the dysfunction of bacterial membranes. Furthermore, their efficacies against methicillin-resistant Staphylococcus aureus (MRSA) in both Galleria mellonella and mouse wound infection models were observed. This study underscores the significance of employing genome-guided approaches to identify untapped marine fungi as potential sources for novel antibiotic candidates with unique scaffolds.

OBJECTIVES: To analyze the differential expression and biological functions of circRNAs in the anterior lens capsules of high myopic patients with cataract and their pathogenic roles in the development of this condition. METHODS: Anterior lens capsule specimens were collected intraoperatively from 36 patients with age-related cataract (ARC) and 36 high myopic patients with cataract. Among these, 18 specimens from each group were selected for whole transcriptome sequencing and biological analysis, and the remaining 36 specimens were used for validation of circPDGFRA, circFOXJ3, hsa_circ_0004767, hsa_circ_0007528, ciCRIM1, circMAN1A2, circSLC5A3, and circPTK2 expressions using RT-qPCR. hsa_circ_0007528 was selected for cell experiments to examine its effects on proliferation, migration, and apoptosis of lens epithelial cells (LECs). RESULTS: A total of 16 192 circRNAs were detected in the specimens from both groups, among which 62 circRNAs were differentially expressed (29 upregulated and 33 downregulated). GO and KEGG analyses revealed that the differentially expressed circRNAs were primarily localized in the cytoplasm, nucleoplasm, and endoplasmic reticulum, and were involved in signaling pathways associated with Gap junction and the PI3K-Akt, NF-κB, Jak-STAT, HIF-1, and MAPK signaling pathways. The ceRNA network predicted multiple target genes. RT-qPCR validation results were consistent with the sequencing data. In the LECs, upregulation of hsa_circ_0007528 significantly inhibited cell proliferation and migration and obviously promoted cell apoptosis. CONCLUSIONS The expression profile of circRNAs in the anterior lens capsule of high myopic patients with cataract differs from that of ARC patients. Upregulation of hsa_circ_0007528 inhibits LEC proliferation and migration and promotes cell apoptosis.

Objective To evaluate the influencing factors of aspiration in neurological critically ill patients by Meta-analysis.Methods PubMed,Embase,Web of Science,CNKI,and Wanfang Data were searched from inception to 1 October,2023,to obtain relevant studies on influencing fac-tors of aspiration in neurological critically ill patients.The literature screening,data extraction and quality evaluation were completed by two researchers.RevMan 5.4 and Stata 13.0 software were ap-plied for pooled Meta-analysisand assessed publication bias,respectively.Results A total of 8 arti-cles,including 1,315 neurocritical care patients,were included in this study.Nine influencing factors related to aspiration were extracted for Meta-analysis.The Meta-analysis results showed that the three influencing factors that caused aspiration in neurocritical care patients were stroke history(OR=5.03,95％CI,2.71 to 9.32,P＜0.000 01),National Institutes of Health Stroke Scale(NIHSS)score＞10(OR=3.35,95％CI,1.75 to 6.42,P=0.000 3),and gastric residual volume＞150mL(OR=7.13,95％CI,2.55 to 9.96,P=0.001).Conclusion This study provides a scientific basis for clinical healthcare professionals to early identify high-risk patients for aspiration,take targeted inter-vention measures,and prevent the occurrence of aspiration.

Objective To explore the influencing factors of cognitive impairment in non-dialysis patients with chronic kidney disease(CKD).Methods A total of 60 hospitalized non-dialysis patients with CKD in the Department of Nephrology of Northern Jiangsu People's Hospital Affiliated to Yangzhou University from September 2022 to September 2023 were enrolled as research objects.According to the estimated glomerular filtration rate(eGFR),they were divided into stage 1 to 2 of CKD group[eGFR ≥60 mL/(min·1.73 m2)]with 23 cases,the stage 3 of CKD group[eGFR 30～＜60 mL/(min·1.73 m2)]with 20 cases,and stage 4 to 5 of CKD group[eGFR＜30 mL/(min·1.73 m2)]with 17 cases.The Montreal Cognitive Assessment Scale(MoCA)was used to evaluate the cognitive function of the patients.Basic data and common clinical laboratory in-dicators on hospital admission were collected to analyze the differences in cognitive function levels under different renal function statuses and to explore the influencing factors of cognitive impairment.Results The incidence rates of cognitive impairment in the stage 1 to 2 of CKD group,stage 3 of CKD group,and stage 4 to 5 of CKD group were 47.8％,85.0％,and 94.1％respectively,the median MoCA scored 26,24 and 20 respectively,with statistically significant between-group differ-ences(P＜0.05).Cognitive function was significantly negatively correlated with age(r=-0.634,P＜0.001),blood urea nitrogen(BUN)(r=-0.574,P＜0.001),serum creatinine(Cr)(r=-0.417,P＜0.001),cystatin C(Cys-C)(r=-0.327,P=0.011),serum β2-microglobulin(β2-MG)(r=-0.259,P=0.046),and N-terminal pro-brain natriuretic peptide(NT-proBNP)(r=-0.474,P＜0.001),and was significantly positively correlated with hemoglobin(HB)(r=0.401,P=0.001)and eGFR(r=0.485,P＜0.001).Multivariate Logistic regression analysis showed that age(P=0.006)and NT-proBNP(P=0.041)were influencing factors of cognitive im-pairment in non-dialysis patients with CKD.Receiver operating characteristic(ROC)curve analysis showed that the area under the curve(AUC),sensitivity,and specificity of age for prediction were 0.860,0.864 and 0.812 respectively,the AUC,sensitivity,and specificity of NT-proBNP for pre-diction were 0.808,0.795 and 0.875 respectively,and the combined prediction of age and NT-proBNP had an AUC,sensitivity,and specificity of 0.893,0.955,and 0.750,respectively.Conclusion As renal function deteriorates,the incidence rate and severity of cognitive impairment in non-dialysis patients with CKD tend to increase.Advanced age,renal function deterioration,high NT-proBNP level,and anemia are associated with the occurrence of cognitive impairment in non-di-alysis patients with CKD,among which age and NT-proBNP are influencing factors for cognitive im-pairment.

This report described a neonate with dehydrated hereditary stomatocytosis (DHSt) presented as a PIEZO1 gene variant. The infant was transferred to the neonatal unit due to severe anemia indicated by umbilical artery blood gas analysis. Physical examination revealed generalized pallor with pale gums, nail beds, and conjunctivae, but no hepatosplenomegaly. Laboratory findings showed markedly reduced hemoglobin (82 g/L), elevated reticulocyte count (320.30×10 9/L), and increased reticulocyte percentage (13.27%). Jaundice developed at 18 hours of age, with a peak total serum bilirubin at 137.1 μmol/L (predominantly indirect) by 24 hours, confirming neonatal hyperbilirubinemia. Whole-exome sequencing identified a heterozygous missense variant in PIEZO1 [c.6280C>T (p.Leu2094Phe)], inherited from the asymptomatic father. The infant was diagnosed with DHSt and treated with packed red blood cell transfusion and phototherapy, achieving clinical stabilization prior to discharge. Follow-up at six and seven months showed normalized hematologic parameters. At 11 months, developmental milestones were age-appropriate, though mild anemia persisted (hemoglobin 110 g/L), prompting dietary iron supplementation.

Objective To evaluate the safety and efficacy of the Neuroform EZ self expanding stent for severe symptomatic intracranial atherosclerotic stenosis(sICAS).Methods Retrospectively enrolled consecutive patients with severe sICAS who underwent percutaneous transluminal angioplasty and stenting(PTAS)with a Neuroform EZ stent in the Department of Cerebrovascular Disease,Henan Provincial People's Hospital,from March 2020 to December 2022.Baseline demographic and clinical data were collected,including age,sex,hypertension,diabetes mellitus,coronary artery disease,dyslipidemia,hyperhomocysteinemia,transient ischemic attack(TIA)and ischemic stroke,smoking history,modified Rankin scale(mRS)score at admission,and National Institutes of Health stroke scale(NIHSS)score.Preoperative imaging data included target vessel(basilar artery,intracranial segment of the internal carotid artery,middle cerebral artery,and intracranial vertebral artery),lesion length,degree of stenosis,and vascular morphology according to the Mori classification(type A,lesion length＜5 mm with concentric or moderately eccentric stenosis;type B,lesion length＜10 mm with severely eccentric stenosis;type C,lesion length＞10 mm or arterial angulation＞90°).Technical success was defined as accurate delivery and deployment of the stent with complete coverage of the target lesion and immediate post deployment residual stenosis＜50%.Postoperative head CT was performed to detect intracranial hemorrhage.Periprocedural complications were recorded,including intracranial hemorrhage,arterial dissection,in stent thrombosis,and perforator occlusion occurring intraoperatively within 72 hours after the procedure.At one-month post-operation,patients were seen through outpatient follow-up for TIA,hemorrhagic or ischemic stroke,and all cause death.At 6 months after surgery,DSA or CT angiography(CTA)was performed to assess in stent restenosis(ISR,defined as＞50%stenosis within the stent or within5mm of its edges,or＞20%luminal loss).At 1 and 2 years postoperatively,ipsilateral ischemic stroke or TIA recurrence was assessed by outpatient visit or telephone follow up.Results A total of 76 patients with severe sICAS underwent PTAS with a Neuroform EZ stent(56 males,20 females,age 47-80 years,with a mean age of[61±10]years).(1)Within all patients enrolled,40 had middle cerebral artery,16 with basilar artery,6 with intracranial vertebral artery and 14 with intracranial internal carotid artery.The preprocedural lesion length was 2-15 mm,with a mean length of(6.2±2.5)mm,and stenosis severity was70%-99%,the mean severity was(83.2±6.9)%,with Mori type B being the most common type(57.9%[44/76]).(2)PTAS was successfully completed on all patients(technical success 100%).Pre dilation with a conventional balloon was performed in all cases(using balloon with diameter of 1.5-3.5mm,and stent with diameter of 2.5-4.5 mm and length of 15-30 mm).Immediate post procedural residual stenosis was(17.4±9.0)%,significantly lower than baseline(t=52.9,P＜0.05),with a mean difference of 65.8%(95%CI63.3%-68.3%).(3)Among all 76patients,one patient developed a flow limiting dissection post balloon angioplasty,which recovered after stent deployment.One patient with basilar artery stenosis experienced recurrent ischemic stroke at 5-day postoperatively,presenting with right sided weakness and coughing on liquids.Imaging showed an acute infarct in the left pons,considered perforator occlusion.The overall periprocedural complication rate was 2.6%(2/76).(4)No deaths occurred within 30 days after surgery.Sixty nine patients(90.8%)underwent 6 month imaging follow up with DSA(52 cases)or CTA(17 cases).ISR occurred in 12 patients(17.4%),including 6 asymptomatic and 6symptomatic cases.The ipsilateral ischemic stroke recurrence rate was 6.6%(5/76)at1 year and13.2%(10/76)at2years.Conclusions Neuroform EZstent assisted PTASappears safe and feasible for the treatment of severe sICAS.The long term effectiveness requires confirmation in large,multicenter,prospective studies.
