ObjectiveTo characterize the quality differences among different germplasm and introduced varieties of Bupleurum scorzonerifolium roots(BSR), and explore the underlying molecular mechanisms, providing a basis for high-quality production and quality control. MethodsWild BSR from Yulin(YLW) served as the quality reference, we conducted comparative analysis among YLW, locally domesticated wild germplasm in Yulin(YLC3), Daqing germplasm introduced and cultivated in Yulin(YLDQC3), and locally cultivated germplasm in Daqing(DQC3). A combination of traditional pharmacognostic methods and modern multi-omics analyses was employed, including macroscopic traits(appearance, odor), microscopic features(proportions of cork, phloem, xylem), cell wall component contents(hemicellulose, cellulose, lignin), carbohydrate contents(starch, water-soluble polysaccharides), marker compound contents(ethanol-soluble extracts, total saponins, liposoluble extracts, and saikosaponins A, B2, C, D), metabolomics, and transcriptomics, in order to systematically characterize quality differences and investigate molecular mechanisms among these samples. ResultsMacroscopically, Yulin-produced BSR(YLW, YLC3, YLDQC3) exhibited significantly greater weight, length, and upper and middle diameters than Daqing-produced BSR(DQC3). Odor-wise, YLW and YLC3 had a a fragrance taste, YLDQC3 had a rancid oil odor, and DQC3 had a sweet and fragrant taste. Microscopically, Yulin germplasm(YLW, YLC3) and Daqing germplasm(YLDQC3, DQC3) shared similar structural features, respectively. However, Yulin germplasm showed significantly higher proportions of cork and phloem, as well as stronger xylem vessel staining intensity compared to Daqing germplasm. Regarding various component contents, Yulin germplasm contained significantly higher levels of ethanol-soluble extracts, total saponins, and saikosaponins A, B2, C, D, while Daqing germplasm had significantly higher levels of hemicellulose, starch, and liposoluble extracts. After introduction to Yulin, the Daqing germplasm(YLDQC3) showed increased starch, water-soluble polysaccharides and liposoluble extracts contents, decreased cell wall component content, but no significant difference in other component contents. Metabolomics revealed that saponins and terpenes accumulated significantly in Yulin germplasm, while alcohols and aldehydes accumulated predominantly in Daqing germplasm. Transcriptomics indicated similar gene expression patterns within the same germplasm but specificity between different germplasms. Integrative metabolomic-transcriptomic analysis identified 145 potential key genes associated with the saikosaponin biosynthesis pathway, including one acetyl-coenzyme A(CoA) acetyltransferase gene(ACAT), one 3-hydroxy-3-methylglutaryl-coenzyme A synthase gene(HMGS), two hydroxymethylglutaryl-CoA(HMG-CoA) reductase genes(HMG), one phosphomevalonate kinase gene(PMK), one 1-deoxy-D-xylose-5-phosphate synthase gene(CLA), one hydroxymethylbuten-1-aldol synthase gene(HDR), two farnesyl pyrophosphate synthase genes(FPPS), one squalene synthase gene(SQS), one β-amyrin synthase gene(BAS), 102 cytochrome P450(CYP450) gene family members, and 32 uridine diphosphate-glucuronosyltransferase(UGT) gene family members. ConclusionAmong the three cultivated types, YLC3 most closely resembles YLW in appearance, microscopic features, contents of major bioactive constituents, metabolomic and transcriptomic profiles. Yulin germplasm exhibits superior saponin synthesis capability compared to Daqing germplasm, and Yulin region is more suitable for the growth of B. scorzonerifolium. Based on these findings, it is recommended that artificial cultivation in northern Shaanxi and similar regions utilize the local Yulin germplasm source cultivated for at least three years.

OBJECTIVE:
To analyze the clinical characteristics, treatment, and prognosis of seven pediatric patients with Acute myeloid leukemia (AML) positive for the t(16;21)(p11;q22) FUS::ERG fusion gene.
METHODS:
A retrospective analysis was carried out on the clinical data, treatment, and prognosis of seven AML patients with t(16;21)(p11;q22) FUS::ERG fusion gene admitted to Henan Children's Hospital between June 2015 and November 2024. Relevant literature was also reviewed. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: 2024-102-001).
RESULTS:
Among 297 pediatric patients with AML, 7 cases (2.36%) were positive for the t(16;21)(p11;q22) FUS::ERG fusion gene, including 3 males and 4 females, with a median age of 11 years (range: 3 ~ 12 years). According to the FAB classification, these included 1 case of M2, 3 cases of M5, and 3 cases of AML-not otherwise specified (non-M3). All 7 patients were found to harbor the t(16;21)(p11;q22) translocation, with 3 cases showing additional chromosomal abnormalities. Immunophenotyping revealed universal expression of CD13, CD33, CD34, and CD117, with partial expression of CD56, CD4, CD64, CD123, CD15, CD38, CD11b, HLA-DR, cMPO, and CD16. One patient achieved complete remission (CR) after the first course of DAE (cytarabine + daunorubicin + etoposide) induction chemotherapy but relapsed and discontinued the treatment. Six patients received DAH (cytarabine + daunorubicin + homoharringtonine) induction therapy, of whom 2 achieved CR after two courses and underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT), resulting in an overall CR rate of 42.86%. Five children did not receive allo-HSCT and had a median overall survival of 9 months (range: 6 ~ 18 months). Two children who underwent transplantation achieved bone marrow morphological and molecular biological relapse at 6 and 9 months post-transplantation, respectively. After receiving combined chemotherapy and donor lymphocyte infusion, one child failed to achieve remission and died at 22 months post-transplantation, while the other has been followed up to date with positive fusion gene status. Their overall survival was 25 months and 30 months, respectively.
CONCLUSION
The t(16;21)(p11;q22) FUS::ERG fusion gene is rare in pediatric AML and associated with poor prognosis. Allo-HSCT may mitigate the adverse prognostic impact of the FUS::ERG fusion gene and contribute to prolonged survival.

3.Influence of high copper load on neurobehavior and the sirtuin 3/peroxisome proliferator-activated receptor-γ coactivator-1α signaling pathway in rats
Journal of Apoplexy and Nervous Diseases 2026;43(3):254-258
Objective To investigate the influence of high copper load on neurobehavior in rats and its possible mechanism of action based on the deacetylase sirtuin 3 (SIRT3)/peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) signaling pathway. Methods A total of 50 adult Sprague-Dawley rats were randomly divided into model group and blank group, with 25 rats in each group. The rats in the model group were fed with 1 g/kg high-copper diet and 0.185% copper sulfate solution (prepared using deionized water) to establish a rat model of high copper load, and after 12 weeks, the shuttle box test and the pole-climbing test were used to observe neurobehavioral changes, while Western blotting and immunofluorescent staining were used to measure the protein expression levels of SIRT3 and PGC-1α in hippocampal tissue. Results The shuttle box test showed that compared with the blank group, the model group had a significant reduction in the number of times of active avoidance reaction after stimulation (P<0.01) and significant increases in the times of active avoidance reaction and passive avoidance reaction (P<0.01);the pole-climbing test showed that compared with the blank group, the model group had a significant increase in pole-climbing time(P<0.01). Western blotting and immunofluorescent staining showed that compared with the blank group, the model group had significant reductions in the protein expression levels of SIRT3 and PGC-1α in hippocampal tissue (P<0.05). Conclusion High copper load has a marked influence on the neurobehavior of rats, possibly by regulating the expression of the SIRT3/PGC-1α signal pathway in hippocampal neurons.

Background Pneumoconiosis is the most serious occupational disease in China, among which silicosis accounts for more than 50%. microRNA (miRNA) plays an important role in the occurrence process of silicosis fibrosis, but the mechanism of it has not been fully clarified yet. Objective To explore the molecular mechanism by which miR-411-3p modulates the ubiquitination degradation of SMAD specific E3 ubiquitin protein ligase (SMURF) 2/Smad7, thereby suppressing epithelial-mesenchymal transition (EMT) in mouse alveolar type II epithelial cells and counteracting silica-induced pulmonary fibrosis. Methods Twenty-four 8-week-old SPF male C57BL/6J mice were randomly divided into four groups: Control group, silica group, silica +miR-411-3p agomir-NC group, and silica +miR-411-3p agomir group, with 6 mice in each group. Silicosis model was prepared by a one-time bronchial infusion of silicon dioxide (SiO2) (200 mg·mL-1, 50 μL). In vitro MLE-12 cells were divided into (1) control group and SiO2 group, (2) SiO2+negative control siRNA (siRNA-NC) group and SiO2+Smurf2 gene silencing (si-Smurf2) group, (3) SiO2+solvent (DMSO) group and SiO2+protease inhibitor (MG132) group, (4) mutant sequence plasmid (Mut)+miR-411-3p mimic control (miR-NC) group, Mut+miR-411-3p mimic group, wild sequence plasmid (Wt)+miR-NC group, and Wt+miR-411-3p mimic group, (5) SiO2+miR-NC group and SiO2+miR-411-3p mimic group. The pathological morphology and collagen deposition of lung tissue were observed after staining. Detection of miR-411-3p and proteins was conducted by real-time fluorescent quantitative PCR and Western blot. The binding of SMURF2 to Smad7 protein and Smad7 to ubiquitin (Ub) were detected by co-immunoprecipitation (Co-IP) method. Dual-luciferase reporter gene assay was adopted to verify the regulatory effect of miR-411-3p on Smurf2. Results In the SiO2-induced MLE-12 cells, compared to the control group, the SiO2-treated group showed significantly upregulated expressions of N-cadherin (N-Cad), collagen I (CoL I), SMURF2, transforming growth factor-β1 (TGF-β1), and phosphorylated Smad2/3 (p-Smad2/3). In contrast, the expressions of E-cadherin (E-Cad), Smad7, and miR-411-3p were significantly downregulated (P<0.05). The dual-luciferase reporter gene assay revealed a regulatory effect of miR-411-3p on Smurf2 (P<0.05). Meanwhile, in the MLE-12 cells induced by SiO2, the miR-411-3p mimic down-regulated the protein expressions of SMURF2, N-Cad, CoL I, TGF-β1, and p-Smad2/3, while up-regulated the protein expressions of E-Cad and Smad7 (P<0.05). The silenced Smurf2 gene inhibited the expressions of N-Cad, CoL I, and p-Smad2/3 proteins, while promoted the expressions of E-Cad and Smad7 proteins in the MLE-12 cells (P<0.05). The Co-IP results showed that the binding of SMURF2 to Smad7 was enhanced, and the ubiquitin binding ability of Smad7 was enhanced in the SiO2 group. In the lung tissue of mice, the results of pathological observation with hematoxylin-eosin (HE) and sirius red (VG) staining showed that compared with the agomir-NC, the lesion was relieved in the lung tissue of the miR-411-3p agomir group. Meanwhile, the expressions of SMURF2, N-Cad, CoL I, TGF-β1, and p-Smad2/3 were significantly down-regulated, while the expressions of E-Cad and Smad7 were significantly up-regulated (P<0.05). Conclusion MiR-411-3p alleviates the EMT of alveolar type II epithelial cells and antagonizes silicosis fibrosis progression in mice by inhibiting SMURF2-mediated ubiquitination and degradation of Smad7.

Objective:To explore the trend of hearing changes in infants with GJB2 gene p.V37I mutation at different months. Methods:The subjects were 54 children(108 ears) with p.V37I homozygous or compound heterozygous mutation in GJB2 gene. All the subjects underwent auditory brainstem response, auditory steady-state response, acoustic immittance and other audiological tests. Children were divided into three groups according to their age, 26 cases in group A were ≤3 months old, 17 cases in group B were>3~≤6 months old, and 11 cases in group C were>6 months old. Statistical analysis was performed on the three groups of ABR response threshold, hearing degree, the ASSR average response threshold of four frequencies and the ASSR response thresholds for each frequency of 500, 1 000, 2 000 and 4 000 Hz. Results:Among the 54 cases, 35 were male and 19 were female, with an age rang of 2-27 months and a median age of 4 months. The ABR response threshold of the three groups were ranked from low to high as group A, group B and group C, and the difference was statistically significant(P<0.05). The ABR response thresholds of the three groups were ranked from low to high as group A, group B, and group C. The comparison between groups showed that the ABR response thresholds of group C was higher than that of group A(P=0.006). The proportion of confirmed hearing loss in the three groups was 34.61%, 50.00% and 63.64%, respectively, and the difference of hearing level among the three groups was statistically significant(P<0.05). The comparison between groups showed that the difference between group A and group C was statistically significant(P=0.012), normal hearing accounted for the highest proportion in group A(65.39%), while mild hearing loss accounted for the highest proportion in group C(45.46%). The ASSR average response thresholds of the four frequencies in the three groups were ranked from low to high as group A, group B and group C, and the difference is statistically significant(P<0.05). The comparison between groups showed that response ASSR thresholds of group C was higher than that of group A(P=0.002). Response thresholds of ASSR in each frequency in the three groups were all ranked from low to high as in group A, group B and group C, and the differences were statistically significant(P<0.05). Compared with each other between groups, response ASSR thresholds of group C was higher than those of group A(P=0.003) and group B(P=0.015) at 500 Hz, while response ASSR thresholds of group C was higher than group A at 1 000 Hz(P=0.010) and 2 000 Hz(P<0.001), and there was no statistical difference at 4 000 Hz. Conclusion:The incidence of hearing loss in GJB2 gene p.V37I mutation increased with age, and the degree of hearing loss increased, the hearing progression was mainly 500, 1 000 and 2 000 Hz suggesting regular follow-up and alert to hearing changes.

Objective:To analyze the incidence and impact on the auditory prognosis of vertigo/dizziness in sudden sensorineural hearing loss patients with moderately severe hearing loss and above. Methods:Clinical data of patients with unilateral sudden sensorineural hearing loss hospitalized from January 2008 to December 2022, aged 18-60 years, PTA≥50 dB HL, and within 14 days of onset were selected. Based on the clinical records of sudden sensorineural hearing loss patients, we determined whether they were accompanied by vertigo/dizziness. The degree of hearing loss is referenced to the 2021 WHO grading criteria and divided into the moderately severe, severe, profound, and total deafness groups. The SPSS 22.0 software was applied to analyze the difference in the auditory prognosis between sudden sensorineural hearing loss patients with moderately severe hearing loss and above who have dizziness/vertigo and those who do not. Results:A total of 697 patients with moderately severe hearing loss and above were collected, including 382 males and 315 females, with an average age of(40.8±11.0) years. The proportions of sudden sensorineural hearing loss patients with dizziness/vertigo among those with moderately severe to total deafness hearing loss were 18.4%, 35.7%, 47.9%, and 76.4% respectively. Compared to the moderately severe, severe, profound, and total deafness groups, the difference was statistically significant(P<0.001). The complete recovery rates of sudden sensorineural hearing loss patients with moderately severe to total deafness hearing loss were 28.2%, 25.2%, 18.2%, and 1.9% respectively, and the total effective rates were 72.8%, 83.5%, 86.7%, and 78.0% respectively. There were statistically significant differences in complete recovery rate(P<0.001), significant efficiency rate(P<0.001), effective rate(P=0.026), and no recovery rate(P=0.022) among the moderately severe, severe, profound, and total deafness groups. The differences in complete recovery between sudden sensorineural hearing loss patients with and without vertigo/dizziness were statistically significant in the moderately severe, severe, profound, and total deafness groups(P<0.05), while the total effective rates were only statistically significant in the profound group compared to those without vertigo/dizziness(P<0.05). After inpatient treatment, sudden sensorineural hearing loss patients with dizziness/vertigo had statistically significant final hearing thresholds at 4 000 and 8 000 Hz for moderately severe hearing loss patients, 2 000-8 000 Hz for severe hearing loss patients, 500-8 000 Hz for profound hearing loss patients, and 2 000-8 000 Hz for total deafness patients compared to those without dizziness/vertigo(P<0.05). Conclusion:The higher the degree of hearing loss in patients with moderately severe hearing loss and above, the higher the proportion of accompanied vertigo/dizziness. Patients with vertigo/dizziness have poorer recovery of high-frequency hearing, and the complete recovery rate is significantly lower than the patients without vertigo/dizziness.

Objective:To explore the hearing changes of children with different genotypes of SLC26A4 with enlarged vestibular aqueduct(EVA) using the linear mixed effect model(LMM), providing evidence for the risk prediction of progressive hearing loss. Methods:A total of 48 children with EVA diagnosed in our hospital from January 2017 to January 2024. All subjects underwent two or more auditory tests. According to the results of deafness gene screening and sequencing, the genotypes are divided into: type A: homozygous mutation of c. 919-2A>G, type B: compound heterozygous or heterozygous mutation containing c. 919-2A>G, and type C: no mutation site of c. 919-2A>G of SLC26A4 gene. LMM was used to analyze the hearing thresholds change of 500 Hz, 1 000 Hz, 2 000 Hz, 4 000 Hz and the average in children with different genotypes with age. Results:A total of 92 ears, 314 audiograms of 48 children were included, the median number of audiograms was 3, the median age of initial diagnosis was 4 months, and the median follow-up time was 13 months. According to LMM, the standard deviation of random effects between patients and ears was large. There was no significant difference in hearing thresholds of different frequencies and the average in genotype A, genotype B, and genotype C, indicating that genotype had no effect on hearing threshold. There is an interaction between age and genotype. Taking genotype C as the reference, children with genotype B had the lowest increase in 500 Hz, 1000 Hz, and the average hearing threshold, followed by type A. Conclusion:EVA children exhibit substantial inter-individual/ear hearing threshold variability. Low-frequency thresholds progress slower than high frequencies. Genotype modulates progression rates, with wild-type(Type C) demonstrating fastest deterioration, supporting personalized auditory monitoring strategies.

BackgroundPrenatal depression has an important impact on maternal health and pregnancy outcomes. Previous studies have shown that maternal prenatal depression is associated with social support, and social support is related to fear of childbirth. However, there is limited research on the relationship among maternal prenatal depression, social support and fear of childbirth, and no studies have specifically explored the influence of social support and fear of childbirth on prenatal depression in primiparous women. ObjectiveTo investigate the current status of prenatal depression among primiparous women, and to analyze the correlation between social support and fear of childbirth, and to further explore the influence of social support and fear of childbirth on prenatal depression in this population, so as to provide references for improving their mental health. MethodsA total of 380 primiparous women admitted to the inpatient department of Chengdu Wenjiang District People's Hospital from December 2022 to September 2023 were enrolled as study subjects. A self-made questionnaire, Edinburgh Postnatal Depression Scale (EPDS), Social Support Rating Scale (SSRS) and Childbirth Attitudes Questionnaire (CAQ) were used to conduct the survey. Pearson correlation analysis was employed to examine the relationships between scale scores. Multiple linear regression analysis was conducted to identify influencing factors of prenatal depression. ResultsA total of 380 questionnaires were distributed, with 372 (97.89%) valid responses collected. Among the participants, 222 cases (59.68%) were identified with prenatal depression. Pearson correlation analysis revealed that EPDS score was negatively correlated with SSRS score (r=-0.283, P<0.01) and positively correlated with CAQ score (r=0.341, P<0.01). Multiple linear regression analysis indicated that social support (β=-0.166, P<0.01) and fear of childbirth (β=0.269, P<0.01) were influencing factors of prenatal depression in primiparous women. ConclusionThe prevalence of prenatal depression among primiparous women is concerning, with depression levels showing significant associations with both social support and fear of childbirth.

Objective To investigate the clinical effects of different right lung volume reduction techniques when the donor lung is oversized and mismatched with the recipient. Methods Clinical data of 10 recipients who underwent right lung volume reduction lung transplantation at the First Affiliated Hospital of Xi'an Jiaotong University from October 2022 to June 2024 were collected, including gender, age, primary disease type, and type of transplantation. A retrospective analysis was performed on postoperative complications within 90 days, duration of mechanical ventilation, hospital stay, and survival status to explore the impact of different volume reduction techniques on the survival rate of lung transplant recipients. Results A total of 10 right lung volume reduction recipients were included in this study, with 2 cases of upper lobe reduction, 7 cases of middle lobe reduction, and 1 case of lower lobe reduction. Three recipients developed airway complications (one each with upper, middle, and lower lobe reduction). The 30-day survival rate was 90% and the 1-year survival rate was 70%. One recipient with upper lobe reduction died of septic shock during the perioperative period, one with lower lobe reduction died of airway anastomotic fistula 2 months after surgery, and one with middle lobe reduction died of renal insufficiency 1 year after surgery. All 7 recipients with middle lobe reduction successfully passed the perioperative period, with one case of airway anastomotic stenosis (1/7). The average duration of mechanical ventilation was 71 hours, and the average hospital stay was 26 days. The 30-day survival rate was 7/7, and the 1-year survival rate was 6/7. Conclusions Middle lobe reduction in right lung transplantation surgery has the advantages of low incidence of airway complications, good safety, and minimal loss of lung function, and may be a better right lung volume reduction option with potential for application.
