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.

Objective:To conduct a scoping review on the critical values for lifestyle risk factors in young and middle-aged patients with prediabetes progressing to diabetes, so as to provide a reference for clinical screening, prevention, intervention, and patient self-management.Methods:Guided by the scoping review methodology and framework developed by Arksey et al., research questions were identified. Through systematic searches of Chinese and English literature databases, studies on risk factors in young and middle-aged patients with prediabetes progressing to diabetes published from the establishment of the database to August 11, 2024 were screened. Studies examining critical values for lifestyle risk factors were selected for data extraction, summary of findings, and qualitative analysis.Results:A total of 19 articles were ultimately included. Lifestyle risk factors encompassed diet, exercise, smoking, drinking, and step count. Specific indicators included daily sugar intake >25 grams, weekly exercise time <150 min, daily exercise time <30 min, weekly drinking ≥3 times with ≥180 ml of clear liquor per session, and daily step count <5 000 steps.Conclusions:There are different characteristics and critical values of the influence of various factors on the progress of diabetes. Future research should further standardize criteria and conduct large-scale, multicenter, long-term follow-up studies to establish optimal critical values for lifestyle factors, thereby providing evidence for diabetes screening, prevention, and intervention.

Neurofibromatosis type 1 (NF1) presents with a diverse range of symptoms that can affect the skin, bones, eyes, central nervous system, and other organs. This article reports the diagnosis and treatment process of a patient with NF1 complicated by bilateral severe-to-profound sensorineural hearing loss. Genetic testing revealed a heterozygous variant of NF1 NM_ 000267.3: c.4054_ 4058del(p.Ser1352LeufsTer20, supporting the diagnosis of NF1. After thorough evaluation, a right cochlear implantation was performed, yielding satisfactory postoperative results. This case suggests that NF1 patients may exhibit phenotypic heterogeneity and atypicality, providing a reference for clinicians in the diagnosis and treatment of such patients.

Liver fibrosis is a common outcome of various chronic hepatic insults,characterized by excessive extracellular matrix(ECM)deposition.The precise mechanisms,however,remain largely undefined.This study identified an elevated expression of platelet-activating factor acetylhydrolase 1B3(Pafah1b3)in liver tissues from both carbon tetrachloride(CCl4)-treated mice and patients with cirrhosis.Deletion of Pafah 1b3 significantly attenuated CCl4-induced fibrosis,hepatic stellate cell(HSC)activation,and acti-vation of transforming growth factor-β(TGF-β)signaling.Mechanistically,PAFAH1B3 binds to mothers against decapentaplegic homolog 7(SMAD7),disrupting SMAD7's interaction with TGF-β receptor 1(TβR1),which subsequently decreases TβR1 ubiquitination and degradation.Pharmacological inhibition using 3-IN-P11,a specific Pafah1b3 inhibitor,conferred protective effects against CCl4-induced fibrosis in mice.Furthermore,Pafah 1b3 deficiency reduced hepatic inflammation.Overall,these results establish a pivotal role for Pafahl b3 in modulating TGF-β signaling and driving HSC activation.

Liver fibrosis is a common outcome of various chronic hepatic insults, characterized by excessive extracellular matrix (ECM) deposition. The precise mechanisms, however, remain largely undefined. This study identified an elevated expression of platelet-activating factor acetylhydrolase 1B3 (Pafah1b3) in liver tissues from both carbon tetrachloride (CCl₄)-treated mice and patients with cirrhosis. Deletion of Pafah1b3 significantly attenuated CCl₄-induced fibrosis, hepatic stellate cell (HSC) activation, and activation of transforming growth factor-β (TGF-β) signaling. Mechanistically, PAFAH1B3 binds to mothers against decapentaplegic homolog 7 (SMAD7), disrupting SMAD7's interaction with TGF-β receptor 1 (TβR1), which subsequently decreases TβR1 ubiquitination and degradation. Pharmacological inhibition using 3-IN-P11, a specific Pafah1b3 inhibitor, conferred protective effects against CCl₄-induced fibrosis in mice. Furthermore, Pafah1b3 deficiency reduced hepatic inflammation. Overall, these results establish a pivotal role for Pafah1b3 in modulating TGF-β signaling and driving HSC activation.

One hundred 1-day-old HY-LINE VARIETY BROWN were randomly divided into 5 groups:the blank group,the model group,the Baihuang Zhili decoction low-dose treatment group(1 g/kg),the Baihuang Zhili decoction medium-dose treatment group(2 g/kg)and the Baihuang Zhili decoction high-dose treatment group(4 g/kg).The results showed that:(1)Compared with the model group,Baihuang Zhili decoction could restore the integrity of intestinal mucosal barrier structure and reduce inflammation.It significantly increased the expression of tight junction pro-teins ZO-1,Claudin-1 and Occludin in small intestine(P＜0.05),and significantly decreased the levels of DAO(diamine axidase)and D(-)-lactic acid(P＜0.05).(2)Compared with the model group,Baihuang Zhili decoction could significantly increase the number of goblet cells(P＜0.05).Baihuang Zhili decoction could significantly increase the MUC2 levels of duodenum,and the MUC2 level of ileum in 1 g/kg group and 4 g/kg group was significantly increased(P＜0.05),the MUC2 levels of jejunum in 2 g/kg group were significantly increased(P＜0.05).(3)Compared with the model group,Baihuang Zhili decoction significantly decreased the sIgA level in duodenum and jeju-num(P＜0.05),and the sIgA level in ileum in 1 g/kg group was significantly decreased(P＜0.05).The IgG level in serum was significantly decreased(P＜0.05).Baihuang Zhili decoction could significantly reduce the expression levels of intestinal immune-related genes(IL-1β,IL-2,IL-6,IL-8,TNF-α)(P＜0.05).It could significantly decrease the expression levels of immune-related factors(TNF-α,IFN-γ,IL-1β,IL-2)in tonsil of cecum(P＜0.05).(4)Compared with the model group,Baihuang Zhili decoction could increase Ace,Chao and Shannon index of intestinal flora,reduce Simpson index of intestinal flora,and increase alpha diversity of intestinal microbes.It significantly decreased the relative abundance of Proteobacteria(P＜0.05),and significantly increased the rela-tive abundance of Campylobacterota(P＜0.05).It also significantly decreased the relative abun-dance of Lactobacillus(P＜0.05).In summary,Baihuang Zhili decoction can improve the damage of intestinal mechanical barrier,chemical barrier,immune barrier and microbial barrier caused by pul-lorum disease,and enhance the intestinal immunity.

Respiratory syncytial virus(RSV)is a major cause of severe lower respiratory disease and can infect all populations,posing a significant health threat to infants and the elderly.After more than 60 years of research,there are only 2 RSV vaccines and 2 preventive monoclonal antibodies be licensed,but the use of the population is severely limited,expensive and difficult to large-scale popularization.RSV vaccine development faces a number of obstacles,such as the lack of animal models,avoidance of RSV immunity,and short duration of immunity.Since the failure of formalin inactivated RSV vaccine trials,RSV vaccine development has become more cautious and difficult.This article briefly reviews the research status of RSV vaccines,and introduces several representative vaccines currently under development,in order to facilitate researchers to review the latest progress and contribute to promoting vaccine research.

Objective To observe the value of contrast-enhanced CT radiomics combined with clinical and hematology indicators for predicting lymph node(LN)metastasis(LNM)of esophageal squamous cell carcinoma(ESCC).Methods Totally 218 ESCC patients were retrospectively enrolled.Stage pN1 and pN2 were clustering as LNM(n=90),while stage pN0 were taken as non-LNM(n=128).The patients were divided into training set(n=174)and test set(n=44)at the ratio of 8∶2.In training set,clinical and LN imaging features which could be used to independently judge LNM were screened and a clinical-imaging model was constructed.The hematological indicators that might be associated with ESCC LNM were screened,and a hematological model was constructed.Radiomics features in LN ROI and ESCC volume of interest(VOI)were extracted based on venous-phase contrast-enhanced CT images,and those might be associated with LNM were screened,and a radiomics model was constructed.Finally a combined model was constructed based on all the above features.The efficacy of each model for diagnosing LNM was evaluated with the area under the curve(AUC)of receiver operating characteristic curves,and the clinical net benefit was evaluated using decision curve analysis(DCA).Results Body mass index(BMI)and internal necrosis of target LN were both independent judging factors for ESCC LNM(both P＜0.05),and AUC of clinical-imaging model for diagnosing LNM in training and test sets was 0.747 and 0.687,respectively.Seven hematological indicators were included in hematological model,and AUC in training and test sets was 0.623 and 0.583,respectively.Ten LN radiomics features and 15 ESCC radiomics features were included in radiomics model,and AUC in training and test sets was 0.769 and 0.745,respectively.AUC of the combined model for diagnosing LNM in training and test sets was 0.822 and 0.739,respectively,better than other models in training set(all P＜0.05),but no significantly different in test set(all P＞0.05).DCA showed that combined model had higher net gain than the other models in 0.55-0.80 threshold probability interval.Conclusion Combined model based on venous-phase contrast-enhanced CT radiomics and clinical and hematology indicators could relatively effectively evaluate ESCC LNM,which might bring some promotions in clinical benefit.
