ObjectiveTo evaluate the antitumor activity of Periplaneta americana extract（PAE） against human-derived lung adenocarcinoma organoids（LUAD-PDOs） and to elucidate its potential mechanism based on transcriptomics. MethodsFresh tumor and adjacent normal tissues from patients with LUAD were collected to construct LUAD-PDOs and normal lung organoid（Nor-PDOs） models using 3D organoid culture technology. The effective intervention concentration of PAE was determined using the cell counting kit-8（CCK-8） assay. Experimental groups included the model group（LUAD-PDOs）， normal group， model administration group（LUAD-PDOs+PAE）， and normal administration group（Nor-PDOs+PAE）. Hematoxylin-eosin（HE） staining was used to observe the pathological structures of PDOs， immunohistochemistry（IHC） was performed to detect the expressions of the proliferation marker Ki-67 and lung adenocarcinoma differentiation markers cytokeratin-7（CK-7） and Napsin A， TUNEL staining was applied to detect cell apoptosis. RNA sequencing（RNA-Seq） was conducted to identify differentially expressed genes（DEGs）， followed by Gene Ontology（GO）， Kyoto Encyclopedia of Genes and Genomes（KEGG）， and Gene Set Enrichment Analysis（GSEA）， alongside protein-protein interaction（PPI） network analysis to screen core mechanisms. Finally， key targets were validated by integrating external database analysis with immunofluorescence（IF）. ResultsNor-PDOs and LUAD-PDOs that highly recapitulated the pathological characteristics of the primary tissues were successfully established. The CCK-8 assay determined that the effective intervention concentration of PAE was 16 g·L^-1. Morphological observation showed that Nor-PDOs exhibited lumen-forming structures， whereas LUAD-PDOs displayed dense， solid structures. CCK-8 and TUNEL assays revealed that， compared with the model group， PAE intervention inhibited the proliferation of LUAD-PDOs and promoted apoptosis in LUAD cells， while showing no significant effect on the viability of Nor-PDOs. Transcriptomic analysis identified 719 DEGs that were significantly reversed after PAE intervention（347 up-regulated and 372 down-regulated）（P<0.05）. GO enrichment analysis indicated that DEGs in the model administration group were significantly enriched in biological processes related to cell cycle regulation compared to the model group. KEGG pathway analysis revealed that PAE affected pathways related to proliferation and metabolism， including pathways in cancer and the p53 signaling pathway. GSEA further confirmed that PAE significantly enhanced the activity of the p53 signaling pathway（P<0.05）. PPI network analysis indicated that breast cancer type 1 susceptibility protein（BRCA1） and checkpoint kinase 1（CHEK1） were the core down-regulated targets in the p53 pathway. IF verified the high expression of BRCA1 and CHEK1 in LUAD-PDOs and their significant downregulation after PAE intervention（P<0.05）. Furthermore， survival analysis based on The Cancer Genome Atlas（TCGA） database indicated that low expression of BRCA1 and CHEK1 was significantly associated with prolonged overall survival in patients with LUAD（P<0.05）. ConclusionPAE effectively inhibits proliferation of LUAD-PDOs and promotes their apoptosis， its anti-tumor mechanism is potentially associated with the activation of the p53 signaling pathway， with BRCA1 and CHEK1 genes likely serving as key downstream targets for the effects of PAE.

ObjectiveCerebrospinal fluid (CSF) plays a crucial role in maintaining the homeostasis of the central nervous system (CNS). CSF rapidly exchanges with interstitial fluid (ISF) via the glymphatic system within the brain parenchyma. CSF-ISF circulation and its associated mechanisms are often referred to as the brain lymphatic system. This system is connected directly to meningeal lymphatic vessels (mLVs), jointly performing the function of clearing metabolic waste from the CNS. Emerging evidence indicates that this system is closely associated with the onset and progression of neurodegenerative diseases (NDs) such as Alzheimer’s disease (AD). Importantly, abnormal CSF circulation is not only a downstream consequence of AD pathology, but also a risk factor. In AD, the dynamics of CSF flow within the CNS are diminished, immune dysregulation occurs, and this may increase the risk of AD by exacerbating the burden of amyloid β-protein (Aβ). In the mouse model of AD, impaired CSF flow compromises this clearance function, leading to cognitive deficits. Clinically, acupuncture at cognition-related acupoints is commonly used for the prevention and treatment of AD. However, whether its therapeutic effects are mediated through the modulation of CSF dynamics remains unclear. This study aimed to evaluate the impact of acupuncture on CSF flow and investigate its acupoint specificity. MethodsMice were randomly assigned to experimental groups for the different electroacupuncture groups with the following acupoints: Baihui point (GV 20), Ear point, Neiguan point (PC 6), and Tianshu point (ST 25). Wild-type mice on a C57BL/6J background were used as controls. Fluorescent tracer was injected into the cisterna magna to label CSF flow. Fluorescence imaging was employed to assess the distribution of CSF within the brain before and after acupuncture stimulation. ResultsFollowing tracer injection into the cisterna magna, fluorescence signals rapidly reached the cerebellum and medulla—the regions closest to the injection site. Fluorescence intensity was higher in ventral brain regions compared to dorsal regions, likely due to greater vascular density in ventral areas facilitating CSF-ISF exchange. Electroacupuncture at the GV 20 produced the most pronounced enhancement of CSF across the whole brain, while stimulation at the ST 25 primarily augmented flow within subcortical regions. In contrast, electroacupuncture at the Ear point or the PC 6 had no observable effect on CSF in mice. ConclusionElectroacupuncture promotes CSF flow into the brain parenchyma in an acupoint-specific manner, with GV 20 exhibiting the most pronounced enhancement of CSF dynamics. These findings suggest that acupuncture-mediated facilitation of CSF flow may represent a potential therapeutic strategy for preventing or delaying age-related cognitive decline.

ObjectiveTo investigate the possible mechanism of Bushen Huoxue Granule （补肾活血颗粒， BHG） in treating Parkinson's disease （PD） from the perspecitve of dopamine （DA） homeostasis. MethodsSeventy-two mice were randomly divided into blank group， model group， madopar group and BHG low-， medium- and high-dose groups， with 12 mice in each group. Except for the blank group， all mice were administered intraperitoneal injections of 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine （MPTP） for 7 consecutive days to induce a PD model. On the day following the injection， BHG low-， medium- and high-dose groups were administered BHG at doses of 1.25， 2.5， and 5.0 mg/（g·d） by oral gavage， respectively， while the madopar group received madopar tablets at dose of 0.093 8 mg/（g·d） by oral gavage. The blank group and the model group were given 0.2 ml/10 g of distilled water by gavage. All treatments were given once daily for 14 days. Open field test， pole climbing test and grip test were used to evaluate the behavior of mice in each group. Immunohistochemistry was used to detect the expression of tyrosine hydroxylase （TH） in striatum. Nissl staining was used to detect the activity of striatal neurons. The contents of DA and 3,4-dihydroxyphenylacetic acid （DOPAC） in striatum were detected by ultra performance liquid chromatography tandem mass spectrometry. The number and volume of synaptic vesicles were observed by transmission electron microscope. The expression of vesicular monoamine transporter 2 （VMAT2） in striatum was detected by immunofluorescence. Western Blot was used to detect the expression of extracellular signal-regulated kinase （ERK）， phosphorylated ERK （p-ERK）， cAMP response element-binding protein （CREB）， phosphorylated CREB （p-CREB） and VMAT2 in striatum. ResultsCompared to the blank group， mice in the model group showed a significant decline in total distance and average speed in the open field test， along with an increase in total resting time； in the pole test， both the time required for the mice to turn completely downward （T-turn） and the total time taken to reach the bottom of the pole （T-total） were prolonged； forelimb grip strength was reduced； in the striatum， the mean optical density of TH， the average fluorescence intensity of VMAT2 protein， and DA content all decreased， while the number of striatal neurons was reduced， and the DOPAC/DA ratio was elevated； the levels of p-ERK/ERK， p-CREB/CREB， and VMAT2 in the striatum significantly decreased （P＜0.01）； transmission electron microscopy revealed that both the number and volume of synaptic vesicles in striatal neurons were markedly reduced. Compared to the model group， mice in the madopar group and BHG low-， medium- and high-dose groups showed significant improvements in all the above indicators （P＜0.05 or P＜0.01）. Compared to madopar group， the BHG high-dose group exhibited increased DA content and elevated p-CREB/CREB ratio in the striatum （P＜0.05）. Compared to the BHG low-dose group， the BHG high-dose group showed increased total distance and mean velocity， decreased total resting time， T-turn， and T-total， as well as enhanced forelimb grip strength； moreover， the average fluorescence intensity of VMAT2 protein， DA content， p-ERK/ERK， p-CREB/CREB， and VMAT2 levels in the striatum were all significantly elevated （P＜0.05 or P＜0.01）. ConclusionBHG may restore DA homeostasis and alleviate the damage of dopaminergic neurons by regulating ERK/CREB/VMAT2 signaling pathway.

Objective:To evaluate the efficacy of ultrasound-guided median interspinous in-plane approach to subarachnoid puncture in obese pregnant patients.Methods:This study was a randomized controlled trial. Eighty obese parturients who underwent elective cesarean section from March 2022 to January 2024 in our hospital were divided into 2 groups( n=40 each) by the random number table method: median interspinous in-plane approach group(group M) and paramedian interlaminar in-plane approach group(group P). After successful puncture, 0.5% ropivacaine 15 mg(3 ml) was intrathecally injected in both groups. The first-attempt success of puncture, the number of puncture attempts, operation time, the total success of puncture, and the visibility scores of the anterior and posterior union, positioning structure(lamina in group P, spinous process in group M) and puncture needle under ultrasound were recorded. Results:Compared with group P, the visibility score of positioning structure under ultrasound was significantly increased, the success rate of puncture at the first attempt was increased, the number of puncture attempts was decreased, the operation time was shortened, the total success rate of puncture was increased( P<0.05), and no significant change was found in the visibility scores of the anterior and posterior union and puncture needle in group M( P>0.05). Conclusions:For obese pregnant patients, the ultrasound-guided median interspinous in-plane approach can accurately and quickly perform subarachnoid puncture, which has more advantages than the traditional paramedian interlaminar in-plane approach.

OBJECTIVE: To investigate the clinical characteristics, treatment and prognosis of adult AML patients with NUP98::HOXA9 fusion gene. METHODS: From May 2017 to October 2023， among 2 113 AML patients who visited the Hematology Department of our hospital, patients with NUP98 rearrangements were screened. The clinical characteristics, chromosome karyotypes, immunophenotypes, gene mutations, treatment efficacy and prognosis of the patients with NUP98::HOXA9 positive were analyzed. RESULTS: Among the 2 113 AML patients, there were 18 cases with NUP98 rearrangement, including 14 NUP98::HOXA9 positive cases, with a detection rate of 0.66% (14/2 113). The median age of the NUP98::HOXA9 positive patients was 42.5 (23-64) years old. The most common chromosome karyotype was t(7; 11)(p15; p15). The immunophenotypes of all patients expressed CD13, CD33, CD117 and CD38, and most patients expressed CD34 and cMPO, while only a few expressed HLA-DR. Second-generation sequencing (NGS) was performed to detect genetic mutations associated with leukemia in all 14 patients, and the genes exhibiting a high frequency of mutation were WT1 (10/14), TET2 (7/14), and FLT3-ITD (6/14). Additionally, mutations were also observed in KRAS/NRAS, IDH1, and KIT. Of the 13 patients who received treatment, 9 achieved complete remission (CR), and all 3 patients who received azacytidine(AZA)+ venetoclax (VEN) regimen achieved CR after the first course of treatment. Within this cohort, 6 patients were classified as relapsed/refractory (6/13). 4 patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT), of which two achieved long-term survival. The median follow-up time was 12 (2.1-65.0) months, while the median overall survival (OS) and relapse-free survival (RFS) were recorded as 11.4 months and 9.6 months, respectively. CONCLUSION The most common type of NUP98 rearrangement in adults AML patients is NUP98::HOXA9 , which is often accompanied by somatic mutations in WT1, TET2, and FLT3-ITD. These patients are prone to relapse, have short survival time, and generally face poor prognoses. Hopefully, utilization of the AZA+VEN regimen is anticipated to enhance the rate of induced remission in the patients, and some patients may prolong their survival through allo-HSCT. However, more effective treatment methods are still needed to improve the overall prognosis of these patients.

AIM To investigate the protective effects of verbascoside on D-galactose-induced liver injury in mice and its underlying mechanisms.METHODS C57BL/6J mice were randomly assigned to the normal group,the model group,the vitamin E group(100 mg/kg),and the low-dose and high-dose verbascoside groups(40,80 mg/kg),with 10 mice in each group.Simultaneous administration of medicine and subcutaneous injection of D-galactose(600 mg/kg)went on among the groups except the normal group for 8 weeks.Serum ALT,AST,ALP activities,along with TBil levels were measured using biochemical kits.Hepatic GSH,MDA concentrations,as well as SOD and GSH-Px activities were quantified.Liver pathological morphology was evaluated by HE staining,while hepatic fibrosis area was assessed using Sirius red staining.Western blot analysis determined hepatic expression of IL-6,IL-1β,TNF-ɑ,TLR4,NF-κB p65,IκBɑ and p-IKBɑ proteins.RESULTS Compared to the model group,the groups treated with vitamin E or verbascoside demonstrated significantly reduced body weight(P＜0.05,P＜0.01);increased hepatic index(P＜0.05,P＜0.01);decreased serum activities of ALT,AST and ALP alongsided reduced TBil levels(P＜0.05,P＜0.01);attenuated pathological damage of liver tissue and fibrosis severity;reduced hepatic MDA level(P＜0.05,P＜0.01);and elevated GSH level with enhanced SOD and GSH-Px activities(P＜0.05,P＜0.01).Furthermore,the high-dose verbascoside group showed significantly decreased hepatic expressions of IL-6,IL-1 β,TNF-ɑ,TLR4,NF-κB p65,and p-IKBɑ/IKBɑ proteins(P＜0.05,P＜0.01).CONCLUSION Verbascoside improves D-galactose-induced liver injury through its antioxidant activity,anti-inflammatory effects,and suppression of the TLR4/NF-κB signaling pathway.

OBJECTIVE To evaluate the economic burden of the intensive care unit(ICU)patients due to hospital-associated multidrug-resistant organisms(MDROs)infections based on propensity score matching(PSM)so as to provide evidence-based bases for prevention and control of hospital-associated MDROs infection and improvement of utilization efficiency of medical resources.METHODS A total of 2118 patients who were hospitalized in Zibo Central Hospital from Jan.1,2023 to Dec.31,2024 and conformed to the inclusion and exclusion criteria were re-cruited as the research subjects.The patients with hospital-associated MDROs infections were matched in a 1∶1 ratio by PSM(with the clamp value 0.02).Totally 309 pairs were successfully matched.The length of hospital stay and the costs were observed and compared between the MDROs group and the non-MDROs group.RESULTS The MDROs group was with the length of hospital stay 14.00 days longer than the non-MDROs group after the matching(Z=-5.750,P＜0.001),with the total cost of hospitalization increased by 91,420.84 yuan(Z=-8.271,P＜0.001).With the respect to the medical treatment expenses,the expenses of the MDROs group were higher than those of the non-MDROs group,covering the cost of medical service,therapeutic procedures,nursing,western medicine and TCM,and there were significant differences(P＜0.05).Among the differences in the costs between the two groups,the difference in the cost of western medicine was the most signif-icant(22,182.91 yuan),followed by the cost of clinical laboratory test for diagnosis(19,529.60 yuan)and the cost of therapeutic procedures(16,333.50 yuan).CONCLUSIONS The hospital-associated MDROs infections may lead to the extension of hospital stay length of the ICU patients,which then increases the economic burden.There-fore,it is necessary to strengthen the multidisciplinary collaboration and formulate corresponding measures so as to reduce the risk of such infections among the ICU patients.

OBJECTIVES: To develop a risk prediction model for left ventricular adverse remodeling (LVAR) based on cardiac magnetic resonance (CMR) parameters in patients undergoing percutaneous coronary intervention (PCI) for acute ST-segment elevation myocardial infarction (STEMI). METHODS: A total of 329 acute STEMI patients undergoing primary PCI at 8 medical centers from January, 2018 to December, 2021 were prospectively enrolled. The parameters of CMR, performed at 7±2 days and 6 months post-PCI, were analyzed using CVI42 software. LVAR was defined as an increase >20% in left ventricular end-diastolic volume or >15% in left ventricular end-systolic volume at 6 months compared to baseline. The patients were randomized into training (n=230) and validation (n=99) sets in a 7∶3 ratio. In the training set, potential predictors were selected using LASSO regression, followed by univariate and multivariate logistic regression to construct a nomogram. Model performance was evaluated using receiver-operating characteristic (ROC) curves, area under the curve (AUC), calibration curves, and decision curve analysis. RESULTS: LVAR occurred in 100 patients (30.40%), who had a higher incidence of major adverse cardiovascular events than those without LVAR (58.00% vs 16.16%, P<0.001). Left ventricular global longitudinal strain (LVGLS; OR=0.76, 95% CI: 0.61-0.95, P=0.015) and left atrial active strain (LAAS; OR=0.78, 95% CI: 0.67-0.92, P=0.003) were protective factors for LVAR, while infarct size (IS; OR=1.05, 95% CI: 1.01-1.10, P=0.017) and microvascular obstruction (MVO; OR=1.26, 95% CI: 1.01-1.59, P=0.048) were risk factors for LVAR. The nomogram had an AUC of 0.90 (95% CI: 0.86-0.94) in the training set and an AUC of 0.88 (95% CI: 0.81-0.94) in the validation set. CONCLUSIONS LVGLS, LAAS, IS, and MVO are independent predictors of LVAR in STEMI patients following PCI. The constructed nomogram has a strong predictive ability to provide assistance for management and early intervention of LVAR.

OBJECTIVE: To investigate the efficacy and safety of autologous blood transfusion during weaning from venous-arterial extracorporeal membrane oxygenation (VA-ECMO) under controlled rotational speed. METHODS: A retrospective study was conducted, selecting patients who underwent extracorporeal membrane oxygenation (ECMO) and successfully weaned at the emergency and critical care medicine center of Henan Provincial Third People's Hospital from January 2023 to May 2024. General data including gender, age, body mass index (BMI), European system for cardiac operative risk evaluation (EuroScore), and disease types were collected. Vital signs at weaning [heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and peripheral oxygen saturation], parameters before and after weaning [B-type natriuretic peptide (BNP), hemoglobin (Hb), partial pressure of arterial oxygen (PaO₂), partial pressure of arterial carbon dioxide (PaCO₂), arterial lactate, central venous pressure (CVP), inferior vena cava collapsibility index, left ventricular ejection fraction (LVEF), and right heart load], post-weaning inflammatory markers at 1-day and 3-day [body temperature, white blood cell count (WBC), neutrophil percentage (NEU%), C-reactive protein (CRP), procalcitonin (PCT), interleukin-10 (IL-10)], as well as complications (infection, thrombosis, renal failure, gastrointestinal bleeding) and post-weaning blood return status were recorded. Patients were divided into an observation group (with post-weaning blood return) and a control group (without post-weaning blood return) based on the presence of blood return after weaning. The changes in the aforementioned parameters were compared between the two groups. RESULTS: A total of 62 patients were included, with 31 cases in each group. No statistically significant differences were observed between the two groups in baseline characteristics including gender, age, BMI, and EuroScore. At weaning, the observation group exhibited relatively stable vital signs, with no significant differences in heart rate, SBP, DBP, or peripheral oxygen saturation compared to the control group. After weaning, the observation group showed significantly lower levels of BNP, PaCO₂, arterial lactate, CVP, and right heart load compared to pre-weaning values [BNP (ng/L): 2 325.96±78.51 vs. 4 878.48±185.47, PaCO₂ (mmHg, 1 mmHg≈0.133 kPa): 35.23±3.25 vs. 40.75±4.41, arterial lactate (mmol/L): 2.43±0.61 vs. 6.19±1.31, CVP (cmH₂O, 1 cmH₂O≈0.098 kPa): 8.32±0.97 vs. 15.34±1.74, right heart load: 13.24±0.97 vs. 15.69±1.31, all P < 0.05], while Hb, PaO₂, inferior vena cava collapsibility index, and LVEF were significantly higher than pre-weaning values [Hb (g/L): 104.42±9.78 vs. 96.74±6.39, PaO₂ (mmHg): 94.12±7.78 vs. 75.51±4.39, inferior vena cava collapsibility (%): 28±7 vs. 17±3, LVEF (%): 62.41±6.49 vs. 45.30±4.51, all P < 0.05]. No statistically significant differences were found between the observation group and control group in these parameters. At 3 days post-weaning, the observation group demonstrated significantly lower levels of body temperature, WBC, NEU%, CRP, PCT, and IL-10 compared to 1 day post-weaning [body temperature (centigrade): 36.83±1.15 vs. 37.94±1.41, WBC (×10⁹/L): 7.82±0.96 vs. 14.34±2.15, NEU%: 0.71±0.05 vs. 0.80±0.07; CRP (mg/L): 4.34±0.78 vs. 8.94±1.21, PCT (μg/L): 0.11±0.02 vs. 0.26±0.05, IL-10 (ng/L): 8.93±1.52 vs. 13.51±2.17, all P < 0.05], with no significant differences compared to the control group. No statistically significant differences were observed between the two groups in the incidence of complications including infection, thrombosis, renal failure, and gastrointestinal bleeding. CONCLUSION Autologous blood reinfusion during VA-ECMO weaning under controlled rotational speed is safe and effective, without increasing risks of infection or thrombosis.
