OBJECTIVE To evaluate the efficacy and safety of amoxicillin combined with proton pump inhibitor （PPI） or potassium-competitive acid blocker （P-CAB） for Helicobacter pylori （Hp） eradication. METHODS Randomized controlled trial （RCTs） on amoxicillin combined with PPI or P-CAB for Hp eradication were retrieved from PubMed， Embase， the Cochrane Library， Web of Science， CNKI， Wanfang， and VIP data. The search time frame was from database inception to September 5， 2025. After literature screening， data extraction， and quality assessment， a network meta-analysis was performed using Stata 17.0 software. RESULTS A total of 12 RCTs involving 5 515 patients were included， encompassing 8 therapeutic regimens： PPI combined with high-dose amoxicillin for 14 days （TR1）， PPI combined with low-dose amoxicillin for 14 days （TR2）， P-CAB combined with high-dose amoxicillin for 7 days （TR3）， P-CAB combined with high-dose amoxicillin for 14 days （TR4）， P-CAB combined with high-dose amoxicillin for 10 days （TR5）， P-CAB combined with low-dose amoxicillin for 7 days （TR6）， P-CAB combined with low-dose amoxicillin for 14 days （TR7）， and P-CAB combined with low-dose amoxicillin for 10 days （TR8）. The network meta-analysis results showed that， in terms of intention-to-treat Hp eradication rates， the eradication rates of TR5 and TR4 were significantly higher than those of TR3， TR8， TR6 and TR1 （ P ＜0.05）. The surface under the cumulative ranking curve （SUCRA） values from highest to lowest were： TR4 （89.7%）＞TR5 （82.3%）＞TR7 （71.5%）＞ TR2 （48.6%）＞TR1 （43.9%）＞TR8 （28.7%）＞TR3 （22.7%）＞TR6 （12.6%）. Regarding safety， the incidence of adverse reactions in TR3 and TR5 was significantly lower than that in TR1 （ P ＜0.05）. The SUCRA values from highest to lowest were： TR1 （91.3%）＞TR4 （79.8%）＞TR5 （55.0%）＞TR7 （50.9%）＞TR8 （41.3%）＞TR2 （36.4%）＞TR3 （27.6%） ＞TR6 （17.7%）. CONCLUSIONS Although the regimen of P-CAB combined with high-dose amoxicillin for 14 days demonstrates the best efficacy， the combination of P-CAB with high-dose amoxicillin for 10 days exhibits a better balanced profile in terms of both efficacy and safety.

ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy （DR）. MethodsFourteen research centers participated in this study， which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group （120 cases） and a control group （120 cases）. The observation group was treated with Tangning Tongluo tablets， and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision， DR progression rate， retinal microhemangioma， hemorrhage area， exudation area， glycosylated hemoglobin （HbA1c） level， and TCM syndrome score were assessed before and after treatment， and the safety was observed. ResultsThe vision changed in both groups after treatment （P<0.05）， and the observation group showed higher best corrected visual acuity （BCVA） than the control group （P<0.05）. The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups， while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment， the number of microhemangiomas decreased in both the observation group （Z=-1.437， P<0.05） and the control group （Z=-2.238， P<0.05）， and it showed no significant difference between the two groups. As the treatment time prolonged， the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment， the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment， neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time， both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR， being capable of improving vision and reducing hemorrhage and exudation in the fundus.

Tumor drug resistance is an important problem in the failure of chemotherapy and targeted drug therapy, which is a complex process involving chromatin remodeling. SWI/SNF is one of the most studied ATP-dependent chromatin remodeling complexes in tumorigenesis, which plays an important role in the coordination of chromatin structural stability, gene expression, and post-translation modification. However, its mechanism in tumor drug resistance has not been systematically combed. SWI/SNF can be divided into 3 types according to its subunit composition: BAF, PBAF, and ncBAF. These 3 subtypes all contain two mutually exclusive ATPase catalytic subunits (SMARCA2 or SMARCA4), core subunits (SMARCC1 and SMARCD1), and regulatory subunits (ARID1A, PBRM1, and ACTB, etc.), which can control gene expression by regulating chromatin structure. The change of SWI/SNF complex subunits is one of the important factors of tumor drug resistance and progress. SMARCA4 and ARID1A are the most widely studied subunits in tumor drug resistance. Low expression of SMARCA4 can lead to the deletion of the transcription inhibitor of the BCL2L1 gene in mantle cell lymphoma, which will result in transcription up-regulation and significant resistance to the combination therapy of ibrutinib and venetoclax. Low expression of SMARCA4 and high expression of SMARCA2 can activate the FGFR1-pERK1/2 signaling pathway in ovarian high-grade serous carcinoma cells, which induces the overexpression of anti-apoptosis gene BCL2 and results in carboplatin resistance. SMARCA4 deletion can up-regulate epithelial-mesenchymal transition (EMT) by activating YAP1 gene expression in triple-negative breast cancer. It can also reduce the expression of Ca²⁺ channel IP3R3 in ovarian and lung cancer, resulting in the transfer of Ca²⁺ needed to induce apoptosis from endoplasmic reticulum to mitochondria damage. Thus, these two tumors are resistant to cisplatin. It has been found that verteporfin can overcome the drug resistance induced by SMARCA4 deletion. However, this inhibitor has not been applied in clinical practice. Therefore, it is a promising research direction to develop SWI/SNF ATPase targeted drugs with high oral bioavailability to treat patients with tumor resistance induced by low expression or deletion of SMARCA4. ARID1A deletion can activate the expression of ANXA1 protein in HER2+ breast cancer cells or down-regulate the expression of progesterone receptor B protein in endometrial cancer cells. The drug resistance of these two tumor cells to trastuzumab or progesterone is induced by activating AKT pathway. ARID1A deletion in ovarian cancer can increase the expression of MRP2 protein and make it resistant to carboplatin and paclitaxel. ARID1A deletion also can up-regulate the phosphorylation levels of EGFR, ErbB2, and RAF1 oncogene proteins.The ErbB and VEGF pathway are activated and EMT is increased. As a result, lung adenocarcinoma is resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Although great progress has been made in the research on the mechanism of SWI/SNF complex inducing tumor drug resistance, most of the research is still at the protein level. It is necessary to comprehensively and deeply explore the detailed mechanism of drug resistance from gene, transcription, protein, and metabolite levels by using multi-omics techniques, which can provide sufficient theoretical basis for the diagnosis and treatment of poor tumor prognosis caused by mutation or abnormal expression of SWI/SNF subunits in clinical practice.

Objective To explore the potential contributors and obstacles of evidence translation for airway hu-midification management in hospitalized patients with laryngectomy tracheostomy and non-mechanical ventilation,so as to provide references for clinical evidence-based practice.Methods An interview outline and questionnaire were developed according to the consolidated framework for implementation research(CFIR).Using purposive sampling,12 healthcare professionals from Department of Otorhinolaryngology,Head and Neck Surgery of a tertiary hospital in Shanxi Province were recruited for semi-structured interviews,and thematic analysis was applied to extract main themes.The interview themes were transformed into survey items,and a survey was conducted among 42 healthcare professionals in the same department.Results Totally 16 contributors and 20 obstacles were identified across 4 domains:the credibility of the evidence and research team,the external support environment for evidence-based practice,the internal conditions for evidence-based practice,and the role recognition of implementers.Contributors include efficient internal collaboration and communication,and rigorous processes for evidence acquisition.Obstacles include insufficient educational resources,low patient knowledge acceptance capacity,lack of professional value a-mong healthcare staff.Conclusion Evidence translation of the humidification management for patients with non-mechanical ventilation after laryngectomy and tracheostomy was influenced by various factors.Future efforts should focus on constructing targeted airway humidification education content and an evaluation index system,and enhanc-ing the professional value and practical leadership of nursing staff.

Objective To investigate the effects of human milk on serum bilirubin levels and gut microbiota in neonatal rats with hyperbilirubinemia.Methods A total of 24 7-day-old specific-pathogen-free Sprague-Dawley rats were injected with bilirubin or normal saline,respectively,and human milk or formula milk was administered 24 hours later for intervention.The rats were divided randomly into four groups:human milk-normal saline group(HN),human milk-bilirubin group(HB),formula milk-normal saline group(FN),and formula milk-bilirubin group(FB).Samples were taken 72 hours later,and serum bilirubin values were detected by enzyme-linked immunosorbent assay.The intestinal microbiota were analyzed using 16S rDNA high-throughput sequencing.Results There was no significant difference in bilirubin values among the groups.Pseudomonas was negatively correlated with indirect bilirubin value(P＜0.05).The composition of the intestinal microbiota differed significantly between human milk and formula milk after gastric administration,with Firmicutes(P＜0.01),Enterococci(P＜0.05),being the main microbiota in the HN and HB groups,and Proteobacteria(P＜0.001),Escherichia Shigella(P＜0.01)and Acinetobacter(P＜0.01)being the main in the FN and FB groups.Conclusions Pseudomonas may be negatively associated with bilirubin,and the structure of the intestinal microbiota may differ in relation to human milk and formula feeding.

Objective To compare the effects of remimazolam and propofol on postoperative nausea and vomiting(PONV)after pancreatic extracorporeal shock wave lithotripsy(P-ESWL),with the aim of optimizing the anesthesia regimen for this procedure.Methods Clinical data were retrospectively collected from patients who underwent P-ESWL for pancreatic stones under general anesthesia at The First Affiliated Hospital of Xi'an Jiaotong University from January 2021 to December 2024.A total of 307 patients were recruited,with 103 in the remimazolam group and 204 in the propofol group.Inverse probability of treatment weighting(IPTW)based on propensity scores was used to balance baseline characteristics and confounding factors between the two groups.The incidence of PONV and anesthesia recovery time were compared between the two groups.Results Before IPTW,there were statistically significant differences between the remimazolam and propofol groups in gender[male/female:51/52 vs.155/49],smoking history(27.2％vs.42.6％),intraoperative sufentanil use[25(10)μg vs.30(10)μg],remifentanil use[429.00(177)μg vs.480.50(209)μg],rocuronium use[36(6)mg vs.38(7)mg],and intraoperative dexamethasone use(62.1％vs.49.0％)(all P＜0.05).After IPTW,the baseline characteristics and confounding factors were balanced and comparable between the two groups(P＞0.05).Before IPTW,the incidence of PONV was higher in the remimazolam group than in the propofol group(24.3％vs.14.7％,P=0.039).After IPTW,the two groups did not significantly differ in the incidence of PONV(21.5％vs.17.5％,P=0.215),and the anesthesia recovery time was significantly shorter in the remimazolam group than in the propofol group[3(3)min vs.9(4)min,P＜0.001].Conclusion Compared to propofol anesthesia,remimazolam does not increase the incidence of PONV in patients undergoing P-ESWL for pancreatic stones and can effectively reduce anesthesia recovery time.

Objective To construct a radiomics model to improve the discriminatory ability of 18 F-PSMA-1007 PET/CT for focal prostate cancer.Methods We retrospectively collected data from 74 patients diagnosed with prostate cancer by biopsy at The First Affiliated Hospital of Xi'an Jiaotong University between July 2020 and April 2024.These patients had focal radionuclide accumulation observed on 18F-PSMA-1007 PET/CT,with the median age of 71 years.Among them,42 patients had a Gleason score＜8 and 32 patients had a Gleason score ≥8.An external validation set was randomly selected based on the timing of examination,while the remaining patients were randomly divided into training and test sets at a 7∶3 ratio.Region of interest(ROI)were semi-automatically drawn on registered images,manually adjusted,and symmetrically shifted to contralateral non-tumor tissue.We made variance and correlation analyses to choose features,and built models with Logistic regression and compared the results with those of visual evaluation.Receiver operating characteristics(ROC)curves were drawn to compare model performance,and subgroup analysis was performed to identify optimal features for distinguishing tumor tissue,based on Gleason score,serum total prostate specific antigen(tPSA)levels,and lesion location.Results A total of eight features were selected.The area under the curve(AUC)for visual evaluation,testing set,and external validation set were 0.858,0.933,and 0.891,respectively.The sensitivity was 0.757,0.800 and 0.917;the specificity was 0.960,0.800 and 0.792,respectively.Subgroup analysis showed that the radiomic features 10percentile and skewness had a high value in tumor differentiation.In tumor tissues,the 10percentile values were higher than in non-tumor tissues across all groups(P-values were 0.012,0.002,＜0.001,＜0.001,＜0.001,and＜0.001).When tPSA≤10 ng/mL and Gleason score ≥8,there was no statistically significant difference in skewness between tumor and non-tumor tissues(P=0.08).When tPSA ≥20 ng/mL,the skewness of non-tumor tissue was slightly higher than that of tumor tissue,but the difference was not statistically significant(P-values were 0.285 and 0.791).When the tumor was located in the posterior part of the prostate(left posterior and right posterior),the skewness was significantly higher in tumor tissue than in non-tumor tissue(P-values＜0.001 for both).Conclusion The radiomics model had better sensitivity and accuracy than visual evaluation in distinguishing focal prostate cancer tumors from non-tumor tissues,but visual evaluation had higher specificity.Skewness and 10percentile had a high value in differential diagnosis.

Immune checkpoint inhibitors are effective tumor treatment agents with survival benefits.However,immune toxicity to various organs has become a new challenge in clinical practice.The cardiac involvement can be presented as heart failure,arrhythmia(atrial fibrillation,atrioventricular block,bundle branch block,ventricular tachycardia,etc.),myocardial-pericarditis,myocardiopathy,and sudden cardiac death,etc.This patient developed abnormally increased myocardial enzymes,impaired cardiac function,and atrioventricular block after 1-month treatment with tislelizumab.Endomyocardial biopsy examination confirmed the diagnosis of immune checkpoint inhibitor-associated myocarditis.Through the diagnosis,treatment,and review of relevant literatures of this case,we wish to improve the understanding of immune checkpoint inhibitor-associated myocarditis,and therefore improve the diagnosis and treatment of immune checkpoint inhibitor-associated myocarditis for clinicians.

Objective To include patients with clinical data matched by propensity scores and to explore the value of 18F-fluorode-oxyglucose(18F-FDG)PET/CT metabolic parameters and radiomics in differentiating benign and malignant solitary pulmonary nod-ule(SPN).Methods A total of 54 patients with SPN(27 benign and 27 malignant)were retrospectively selected,all of them under-went 18F-FDG PET/CT scans.Then the metabolic parameters were analyzed,and the metabolic parameters model was established.After delineating the lesion,imaging features were selected through variance and correlation analysis.The logistic regression was used to build the model,and balance accuracy(bACC)was used to compare the performance of the models.The correlation between meta-bolic parameters and radiomics features was analyzed.Results The maximum standardized uptake value(SUVmax),total lesion uptake(TLU),and coefficient of variation(COV)of malignant were higher than those of benign(P＜0.05).SUVmax and COV had positive predictive value for malignant lesions[odds ratio(OR)＞1,P＜0.05].There was no statistical difference between the performance of the metabolic parameters model and the radiomics model(P＞0.05).There was a strong correlation between radiomics features and metabolic parameters.Conclusion After propensity score matching,metabolic parameters and radiomics show no statistical difference in differentiating benign from malignant SPN.

Objective To investigate the effect of naringenin(Nar)on hippocampal neuronal injury in neonatal mice with bilirubin encephalopathy,focusing on the Nrf2/GPX4-mediated ferroptosis pathway.Methods Neonatal mice were randomly divided into Control group,Model group,Nar low(Nar-L),high dose group(Nar-H)and high dose naringenin combined with Nrf2 inhibitor ML385 group(Nar-H+ML385),with 15 mice in each group.With the exception of the Control group,mice in the other groups were injected with bilirubin solution(20 μg/g)through the cerebellar bulbar cisterna to establish neonatal mouse bilirubin encephalopathy model.After the establishment of the model,intraperitoneal injection of naringin(25 or 100 mg/kg)or ML385(30 mg/kg)was administered once daily for a consecutive period of 7 days.After intervention,the neurobehavioral changes of each group of mice were observed.The water maze experiment was conducted to assess the long-term learning and memory abilities of the mice in each group.Nissl staining was performed to observe hippocampal neuron damage in mice.Chemical methods were used to measure the levels of malondialdehyde(MDA),4-hydroxynonenal(4-HNE),superoxide dismutase(SOD),and glutathione peroxidase(GSH-Px)in the hippocampal tissue of mice.Colorimetric analysis was employed to determine the content of Fe2+in hippocampal tissue.Western blotting was utilized to detect protein expression levels of nuclear associated factor 2(Nrf2),solute carrier family 7 member 11(SLC7A11)and glutathione peroxidase 4(GPX4)protein in the hippocampal tissue of mice.Results Compared with the Control group,the Model group showed different degrees of abnormal neural behavior,and the long-term learning and memory ability were significantly reduced(P<0.05),at the same time,the hippocampal nerve was seriously damaged,and the contents of MDA,4-HNE and Fe2+in hippocampal tissue were significantly increased(P<0.05),the activities of SOD and GSH-Px and the protein expression levels of Nrf2,SLC7A11 and GPX4 were significantly decreased(P<0.05).Compared with the Model group,the Nar-L and Nar-H groups had less abnormal behavior,and the long-term learning and memory ability were significantly enhanced(P<0.05),at the same time,the hippocampal nerve injury was significantly improved,and the contents of MDA,4-HNE and Fe2+in hippocampal tissue were significantly decreased(P<0.05),the activities of SOD and GSH-Px and the protein expression levels of Nrf2,SLC7A11 and GPX4 were significantly increased(P<0.05).However,the combined intervention of ML385 significantly attenuates the beneficial effects of Nar on hippocampal neuron damage in neonatal mice with bilirubin encephalopathy.Conclusion This study suggested that Nar can ameliorate neuronal damage in hippocampus of neonatal mice with bilirubin encephalopathy,possibly through the regulation of iron death mediated by Nrf2/GPX4 axis.
