ObjectiveTo investigate the clinical and pathological features of intrahepatic intraductal papillary neoplasm of the bile duct （IPNB）， and to improve the understanding， diagnosis， and treatment of this disease. MethodsA retrospective analysis was performed for four patients who underwent surgical resection in Beijing Chaoyang Hospital， Capital Medical University， from January 2010 to December 2025 and were diagnosed with intrahepatic IPNB based on pathological examination. The clinical， imaging， and pathological features of these patients were summarized， and a literature review was performed for related articles in China and globally. ResultsAmong the four patients， there were three female patients and one male patient， with a median age of 65 years， and clinical manifestations included jaundice， abdominal pain or diarrhea， and asymptomatic findings on physical examination. The main imaging manifestation was bile duct dilatation or solid-cystic space-occupying lesion. Pathological typing revealed one case each of the gastric， intestinal， pancreatobiliary， and oncocytic types， and there was one patient with low-grade intraepithelial neoplasia and three patients with high-grade intraepithelial neoplasia， among whom one patient also had invasive carcinoma. ConclusionIntrahepatic IPNB is a rare precancerous lesion of the liver with diverse clinical， imaging， and pathological manifestations， and radical surgical resection remains the cornerstone of treatment.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Purpose: This study aimed to evaluate the contrast-enhanced ultrasound with Sonazoid (Sonazoid-CEUS) features of hepatocellular carcinoma (HCC) in patients with non-alcoholic fatty liver disease (NAFLD). Methods: In this retrospective study, patients who underwent surgical resection and were histopathologically diagnosed with NAFLD or cirrhosis-related HCC were included. All patients received Sonazoid-CEUS examinations within 1 week prior to hepatic surgery. The enhancement patterns of HCC lesions were evaluated and compared between the two groups according to the current World Federation for Ultrasound in Medicine and Biology guidelines. Multivariate logistic regression analysis was used to assess the correlations between Sonazoid-CEUS enhancement patterns and clinicopathologic characteristics. Results: From March 2022 to April 2023, a total of 151 patients with HCC were included, comprising 72 with NAFLD-related HCC and 79 with hepatitis B virus (HBV) cirrhosis–related HCC. On Sonazoid-CEUS, more than half of the NAFLD-related HCCs exhibited relatively early and mild washout within 60 seconds (54.2%, 39/72), whereas most HBV cirrhosis–related HCCs displayed washout between 60 and 120 seconds (46.8%, 37/79) or after 120 seconds (39.2%, 31/79) (P<0.001). In the patients with NAFLD-related HCC, multivariate analysis revealed that international normalized ratio (odds ratio [OR], 0.002; 95% confidence interval [CI], 0.000 to 0.899; P=0.046) and poor tumor differentiation (OR, 21.930; 95% CI, 1.960 to 245.319; P=0.012) were significantly associated with washout occurring within 60 seconds. Conclusion Characteristic Sonazoid-CEUS features are useful for diagnosing HCC in patients with NAFLD.

OBJECTIVES: To investigate the relationship between the polygenic risks for various psychiatric disorders and clinical and neuropsychological characteristics in children with attention-deficit/hyperactivity disorder (ADHD). METHODS: Using a cross-sectional design, 285 children with ADHD and 107 healthy controls were assessed using the Child Behavior Checklist, the Behavior Rating Inventory of Executive Function for parents, the Wechsler Intelligence Scale for Children, Fourth Edition, and the Cambridge Neuropsychological Test Automated Battery. Blood samples were collected for genetic data. Polygenic risk scores (PRSs) for various psychiatric disorders were calculated using the PRSice-2 software. RESULTS: Compared with the healthy controls, the children with ADHD displayed significantly higher PRSs for ADHD, major depressive disorder, anxiety disorder, and obsessive-compulsive disorder (P<0.05). In terms of daily-life executive function, ADHD-related PRS was significantly correlated with the working memory factor; panic disorder-related PRS was significantly correlated with the initiation factor; bipolar disorder-related PRS was significantly correlated with the shift factor; schizophrenia-related PRS was significantly correlated with the inhibition, emotional control, initiation, working memory, planning, organization, and monitoring factors (P<0.05). The PRS related to anxiety disorders was negatively correlated with total IQ and processing speed index (P<0.05). The PRS related to obsessive-compulsive disorder was negatively correlated with the processing speed index and positively correlated with the stop-signal reaction time index of the stop-signal task (P<0.05). CONCLUSIONS PRSs for various psychiatric disorders are closely correlated with the behavioral and cognitive characteristics in children with ADHD, which provides more insights into the heterogeneity of ADHD.

OBJECTIVE: This study aimed to determine the expression levels and prognostic significance of MYCN in bone marrow of adult patients with newly diagnosed acute myeloid leukemia (AML). METHODS: A total of 62 newly diagnosed patients with non-M3 AML were enrolled as the study group, and 20 healthy donors as the control group. Real-time quantitative reverse transcription-polymerase chain reaction (PCR) was performed to detect the expression level of MYCN, and the relationship between MYCN expression and prognosis of AML patients was analyzed. RESULTS: MYCN was up-regulated in newly diagnosed AML patients compared with normal controls (P < 0.001). Receiver operating characteristic (ROC) curve analysis revealed that MYCN could serve as a diagnostic biomarker for AML. Kaplan-Meier survival analysis showed that the patients with high MYCN expression had a shorter overall survival (OS) time than the patients with low MYCN expression (P =0.016). The expression level of MYCN was lower during the complete ressimion (CR) phase of AML compared to the initial diagnosis, but it returned to the initial diagnostic level or even higher during relapse phase. Multivariate Cox regression analysis showed that high expression of MYCN was an independent risk factor for OS of AML patients (P =0.021). CONCLUSION MYCN is highly expressed and associated with poor prognosis in de novo AML, which might be serve as a novel diagnostic and prognostic biomarker for adult AML.

Loss of protein homeostasis is a hallmark of cellular senescence, and ribosome pausing plays a crucial role in the collapse of proteostasis. However, our understanding of ribosome pausing in senescent cells remains limited. In this study, we utilized ribosome profiling and G-quadruplex RNA immunoprecipitation sequencing techniques to explore the impact of RNA G-quadruplex (rG4) on the translation efficiency in senescent cells. Our results revealed a reduction in the translation efficiency of rG4-rich genes in senescent cells and demonstrated that rG4 structures within coding sequence can impede translation both in vivo and in vitro. Moreover, we observed a significant increase in the abundance of rG4 structures in senescent cells, and the stabilization of the rG4 structures further exacerbated cellular senescence. Mechanistically, the RNA helicase DHX9 functions as a key regulator of rG4 abundance, and its reduced expression in senescent cells contributing to increased ribosome pausing. Additionally, we also observed an increased abundance of rG4, an imbalance in protein homeostasis, and reduced DHX9 expression in aged mice. In summary, our findings reveal a novel biological role for rG4 and DHX9 in the regulation of translation and proteostasis, which may have implications for delaying cellular senescence and the aging process.

OBJECTIVE: Peritoneal fibrosis (PF) is an adverse event that occurs during long-term peritoneal dialysis, significantly impairing treatment efficiency and adversely affecting patient outcomes. Astragaloside IV (AS-IV), a principal active component derived from Astragalus membranaceus (Fisch.) Bunge, has exhibited anti-inflammatory and antifibrotic effects in various settings. This study aims to investigate the potential therapeutic efficacy and mechanism of AS-IV in the treatment of PF. METHODS: The PF mouse model was established by intraperitoneal injection of 4.25% peritoneal dialysis fluid (100 mL/kg). The epithelial-mesenchymal transition (EMT) of HMrSV5 cells was induced by the addition of 10 ng/mL transforming growth factor β (TGF-β). The differentially expressed genes in HMrSV5 cells treated with AS-IV were screened using transcriptome sequencing analysis. The potential targets of AS-IV were screened using network pharmacology and analyzed using molecular docking and molecular dynamics simulations. RESULTS: Administration of AS-IV at doses of 20, 40, or 80 mg/kg effectively mitigated the increase in peritoneal thickness and the development of fibrosis in mice with PF. The expression of the fibrosis marker α-smooth muscle actin in the peritoneum was significantly decreased in AS-IV-treated mice. The treatment of AS-IV (10, 20, and 40 μmol/L) significantly delayed the EMT of HMrSV5 cells induced by TGF-β, as demonstrated by the decreased number of 5-ethynyl-2'-deoxyuridine-positive cells, reduced migrated area, and decreased expression of fibrosis markers. A total of 460 differentially expressed genes were detected in AS-IV-treated HMrSV5 cells through transcriptome sequencing, with notable enrichment in the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)-AKT serine/threonine kinase 1 (AKT) signaling pathway. The reduced levels of phosphorylated PI3K (p-PI3K) and p-AKT were detected in HMrSV5 cells with AS-IV treatment. Epidermal growth factor receptor (EGFR) was predicted as a direct target of AS-IV, exhibiting strong hydrogen bond interactions. The activation of the PI3K-AKT pathway by the compound 740Y-P, and the activation of the EGFR pathway by NSC 228155 each partially counteracted the inhibitory effect of AS-IV on the EMT of HMrSV5 cells. CONCLUSION AS-IV delayed the EMT process in peritoneal mesothelial cells and slowed the progression of PF, potentially serving as a therapeutic agent for the early prevention and treatment of PF.

Objective To investigate the effects of emergency endovascular treatment on the short-term and long-term prognosis of patients with minor stroke(National Institutes of Health stroke scale[NIHSS]score≤5)caused by posterior circulation large vessel occlusion(LVO).Methods A retrospective analysis was performed on consecutive patients with minor stroke caused by posterior circulation LVO admitted to the Department of Neurology,the First Affiliated Hospital of Xi'an Jiaotong University from July 2019 to March 2024.The patients were divided into the emergency endovascular treatment group and the standard medical treatment group according to the treatment method.Baseline and clinical data were collected from all patients enrolled,including age,sex,smoking history,history of alcohol consumption,medical history(hypertension,diabetes,hyperlipidemia,atrial fibrillation,transient ischemic attack[TIA],blood pressure on admission,stroke history,coronary heart disease),intravenous thrombolysis,tandem lesions,posterior circulation Alberta stroke program early CT score(pc-ASPECTS)on admission,NIHSS score on admission and discharge,time from onset to admission,responsible occluded vessel(basilar artery,left vertebral artery,right vertebral artery),vertebral artery development(left vertebral artery dominant,right vertebral artery dominant,bilateral vertebral artery dominant),non-lesion side vertebral artery development(poor,good,not applicable),basilar artery on CT angiography(BATMAN)score,leptomeningeal branch compensation(open,not open),surgery-related indicators(number of thrombectomy passes[≤2 times,＞2 times],rescue interventions[stent placement,balloon dilation,arterial thrombolysis,intra-arterial tirofiban infusion],immediate postoperative modified thrombolysis in cerebral infarction[mTICI]grade≥2b[successful recanalization],anesthesia method[general,local],endotracheal intubation status[yes,no],duration of mechanical ventilation[not using a ventilator or successfully intubation for≤24 hours and＞24 hours]),in-hospital systematic complications(deep-vein thrombosis,urinary tract infection,lung infection).The primary outcome for short-term prognosis was an excellent outcome(modified Rankin scale[mRS]score of 0-1)within 90 days after onset.Secondary outcomes included a good outcome(mRS score of 0-2)within 90days after onset,recurrent ischemic stroke within 90 days after onset,all-cause mortality within 90 days after onset.Safety outcomes were symptomatic intracerebral hemorrhage(sICH)within 24 hours of treatment(NIHSS score increased by≥4 points or increased level of consciousness score by≥1 point compared with admission,with visible hemorrhagic lesions on follow-up CT scan)and early neurological deterioration(END,NIHSS score increased by≥2 points or motor score increased by≥1 point compared with admission,within 24 hours after treatment).Long-term outcome was defined as recurrent ischemic stroke within 1 year after onset.Short-term and safety outcomes were compared between the emergency endovascular treatment group and the standard medical treatment group.Kaplan-Meier survival curves was used to evaluate the effect of emergency endovascular treatment on the long-term prognosis.Based on the mRS score at 90 days from onset,all patients were divided into an excellent outcome(mRS score 0-1)group and a non-excellent outcome(mRS score 2-6)group.Baseline and clinical data were compared across the two groups.Variables with statistically significant differences were included in the multivariate Logistic regression analysis to investigate the influencing factor of 90-day excellent outcomes in patients with minor stroke caused by posterior circulation LVO.Results A total of 56 patients with minor stroke caused by posterior circulation LVO were enrolled,including 18 patients in the emergency endovascular treatment group and 38 patients in the standard medical treatment group.45 patients achieved excellent outcomes and 11 patients achieved non-excellent outcomes.(1)The emergency endovascular treatment group had lower pc-ASPECTS on admission(8.0[7.0,9.0]points vs.9.0[8.0,10.0]points,P=0.043)and There were no statistically significant differences in the excellent outcome rate,good outcome rate,and ischemic stroke recurrence rate within 90 days after onset between the two groups(all P＞0.05).No all-cause mortality occurred within 90 days after onset in either group.In the emergency endovascular treatment group,one patient developed sICH and one developed END within 24 hours after treatment.(3)No recurrent ischemic stroke in the emergency endovascular treatment group within 1 year after onset,while 3cases(7.89%)of recurrence were observed within 1year after onset in the standard medical treatment group.The Kaplan-Meier survival curve analysis showed that there was no statistically significant difference in the incidence of ischemic stroke within one year after onset between the two groups(P=0.341).(4)There were statistically significant differences between patients with excellent outcome and patients with non excellent outcome in drinking history,diabetes history,NIHSS score after discharge,distribution of responsible occlusive vessels,and distribution of vertebral artery development(all P＜0.05).The results of multivariate Logistic regression analysis showed that the NIHSS score at discharge was an independent influencing factor for excellent outcome at 90 days after onset in patients with minor stroke caused by posterior circulation LVO(OR,0.448,95%CI 0.275-0.728,P=0.001).Conclusions This study shows potential safety and effectiveness of emergency endovascular treatment on patients with minor stroke caused by posterior circulation LVO,but it is not superior to standard medical treatment in terms of short-term and long-term outcomes.Further large-sample randomized controlled trials are warranted to validate the findings of this study.
