Acute kidney injury (AKI) has high morbidity and mortality, but effective clinical drugs and management are lacking. Previous studies have suggested that macrophages play a crucial role in the inflammatory response to AKI and may serve as potential therapeutic targets. Emerging evidence has highlighted the importance of forkhead box protein O1 (FoxO1) in mediating macrophage activation and polarization in various diseases, but the specific mechanisms by which FoxO1 regulates macrophages during AKI remain unclear. The present study aimed to investigate the role of FoxO1 in macrophages in the pathogenesis of AKI. We observed a significant upregulation of FoxO1 in kidney macrophages following ischemia-reperfusion (I/R) injury. Additionally, our findings demonstrated that the administration of FoxO1 inhibitor AS1842856-encapsulated liposome (AS-Lipo), mainly acting on macrophages, effectively mitigated renal injury induced by I/R injury in mice. By generating myeloid-specific FoxO1-knockout mice, we further observed that the deficiency of FoxO1 in myeloid cells protected against I/R injury-induced AKI. Furthermore, our study provided evidence of FoxO1's pivotal role in macrophage chemotaxis, inflammation, and migration. Moreover, the impact of FoxO1 on the regulation of macrophage migration was mediated through RhoA guanine nucleotide exchange factor 1 (ARHGEF1), indicating that ARHGEF1 may serve as a potential intermediary between FoxO1 and the activity of the RhoA pathway. Consequently, our findings propose that FoxO1 plays a crucial role as a mediator and biomarker in the context of AKI. Targeting macrophage FoxO1 pharmacologically could potentially offer a promising therapeutic approach for AKI.

Objective:To investigate the relationship between dynamic alterations in serum albumin (ALB) concentrations and clinical outcomes in hospitalized surgical patients, thus providing a basis for optimizing clinical management strategies.Methods:This study utilized data from a prospective observational cohort study on nutritional status among 7 122 elderly hospitalized patients across 34 tertiary hospitals in 18 Chinese cities. A total of 1 714 surgical patients hospitalized for 7-30 days with complete data were included. Standardized protocols were used to collect demographic data, clinical outcomes, and a range of laboratory results, including nutritional and hematological parameters. Heterogeneous effects of ALB on clinical outcomes were explored. Receiver operating characteristic (ROC) curves were used to determine cutoff values for infection-related complications. Correlation analyses and multiple linear regression models were used to identify independent predictors of the absolute change in ALB (?ALB).Results:Among the surgical patients, 69.7% (1 195/1 714) experienced a decline in ALB levels during their hospital stay, which was significantly associated with the occurrence of both infection- and non-infection-related complications. Simultaneously, a marked decrease in ALB was also significantly correlated with changes in nutritional and inflammatory status during hospitalization, worsening of gastrointestinal symptoms at discharge, and functional activity abnormalities (all P<0.05). ?ALB exhibited a close association with outcome variables such as infection-related complications. Based on the incidence of infection-related complications, a cutoff value for ALB was calculated, dividing patients into a high-risk group ( n=179) and a low-risk group ( n=1 535), and a statistically significant difference in the incidence of infection-related complications was found between these two groups ( P<0.05). Correlation analysis and multiple linear regression modeling revealed that female gender, a higher baseline ALB level, a poorer baseline inflammatory status, an exacerbation of inflammatory status, larger alterations in platelet-to-lymphocyte ratio, and the presence of infection-related complications were predictive factors for a decline in ALB levels among surgical patients during their hospital stay. Conclusions:?ALB serves as a critical indicator of the inflammatory-nutritional interplay, with its magnitude of decline effectively predicting clinical outcomes and nutritional status changes and guiding multidisciplinary interventions in surgical patients.

Objective:To identify risk factors associated with endoscopic atrophic progression of gastric mucosa after Helicobacter pylori ( HP) eradication and to develop a risk scoring system for establishing an individualized endoscopic follow-up strategy for patients with chronic gastritis. Methods:This retrospective cohort study included chronic gastritis patients with successful HP eradication at the Department of Gastroenterology, Beijing Friendship Hospital between January 2018 and October 2021. Demographic characteristics, endoscopic findings, and other clinical data were analyzed. Endoscopic outcomes of gastric mucosal atrophy before and after follow-up were compared to classify patients into progression and non-progression groups. Univariate and multivariate analyses were performed to identify independent risk factors for endoscopic atrophic progression. A risk scoring system was then constructed based on these factors. Results:A total of 218 patients with chronic gastritis were included, including 153 in the non-progression group and 65 in the progression group. Multivariate logistic regression analysis showed that gastric ulcer ( P=0.008, OR=4.24, 95% CI: 1.46-12.25), history of proton pump inhibitor use ( P=0.007, OR=4.06, 95% CI: 1.46-11.27), alcohol consumption ( P=0.002, OR=3.77, 95% CI: 1.64-8.67), high-salt diet ( P=0.008, OR=2.90, 95% CI: 1.32-6.41), and high red meat intake ( P=0.025, OR=2.33, 95% CI: 1.11-6.31) were independent risk factors for endoscopic atrophic progression after HP eradication. The predictive model based on these 5 factors demonstrated strong discriminative capacity, with an area under the receiver operating characteristic curve of 0.813 (95% CI: 0.755-0.876, P<0.001). The optimal cut-off value was 1.5 points, stratifying patients into low-risk (0-2 points) and high-risk (3-5 points) groups. Conclusion:Patients with chronic gastritis remain susceptible to progression even after successful HP eradication. Individualized endoscopic follow-up strategies should be considered based on patients' medical history, medication use, lifestyle, and dietary habits.

Objective To study the levels of serum Periostin and interleukin(I1-)-18 in preterm infants with bronchopulmonary dysplasia(BPD),and to analyze their correlation with the severity of the disease and their predictive value for BPD.Methods A total of 62 preterm infants with BPD diagnosed and treated in the hospital from January 2019 to January 2022 were retrospectively selected as the BPD group,and 80 preterm in-fants without BPD during the same period were selected as the non-BPD group.According to the severity of BPD,the infants with BPD were divided into mild subgroup(22 cases),moderate subgroup(24 cases)and se-vere subgroup(16 cases).The serum levels of Periostin and IL-18 were detected by enzyme-linked immu-nosorbent assay.Pearson correlation analysis was used to analyze the correlation between the clinical parameters.Multivariate Logistic regression was used to analyze the influencing factors of BPD,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for BPD.Results Compared with the non-BPD group,the BPD group had a significantly higher proportion of infants with pulmonary surfactant(PS)use,neonatal respiratory distress syndrome,apnea,patent ductus arteriosus,and serum levels of Periostin and IL-18,as well as a significantly longer duration of mechanical ventilation,noninvasive respiratory support,and length of hospital stay.The lung function parameters[tidal volume per kilogram(VT/kg),ratio of time to peak tidal expiratory flow to time(TPTEF/TE),ratio of volume to peak tidal expiratory flow to volume(VPEF/VE),expiratory flow at 50％tidal volume(50％TEF),expiratory flow at 75％tidal volume(75％TEF)]and 1,5 min Apgar score of BPD group were lower than that of non-BPD group,and the differences were statistically significant(P＜0.05).The serum levels of Periostin and IL-18 in mild subgroup,moderate subgroup and severe subgroup were increased in turn.The levels of serum Periostin and IL-18 were negatively correlated with pulmonary function indexes(VT/kg,50％TEF,75％TEF,TPTEF/TE,VPEF/VE,P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for BPD(P＜0.05),and PS was a protective factor(P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for the severity of BPD(P＜0.05).The area under the curve(95％CI)of serum Periostin and IL-18 alone and in combination for predicting BPD were 0.841(0.814-0.899),0.863(0.820-0.897),0.922(0.878-0.949),respectively.The sensitivity and specificity of combined prediction were 0.902 and 0.825,respectively.The area under the curve of the combination of the two indica-tors for predicting BPD was greater than that of each index alone,and the difference was statistically signifi-cant(Z=5.357,4.894,P＜0.001).Conclusion The levels of serum Periostin and IL-18 are increased in in-fants with BPD,which are related to the severity of BPD and lung function.The combination of serum Perios-tin and IL-18 has a high predictive value for BPD.

Objective:To explore the effects of “Internet plus” management based on attention-interest-search-action-share (AISAS) mode on health-promoting lifestyles in young and middle-aged patients with hypertension.Methods:A prospective randomized controlled trial was used by this study, 212 young and middle-aged patients with hypertension from Cardiovascular Medicine Department of the First Affiliated Hospital of Nanchang University were divided into"Internet plus"management group and routine management group according to the random number table method between January 2021 and January 2023, 106 cases in each group. The regular management group were given regular management intervention, and the “Internet plus” management group were used the “Internet plus” management model intervention based on the AISAS model, each lasting 12 months. All patients were intervened for 12 months. At 1d before discharge, 6 months and 12 months after discharge, health-promoting lifestyles were evaluated by Chinese version of Health Promotion Lifestyle Scale (HPLP-IIC), quality of life were evaluated by the 36-item shot-form health status survey (SF-36), and treatment compliance were evaluated by therapeutic adherence scare for hypertensive patients (TASHP).Results:With discharge time, scores of HPLP-IIC, SF-36 and TASHP were significantly increased in both groups (all P<0.05). At 6 and 12 months after discharge, the scores of HPLP-IIC [(117.58±16.43) and (134.37±20.25) points], SF-36 [(79.58±5.43) and (84.37±3.25) points] and TASHP [(101.84±6.32) and (115.37±4.25) points] in “Internet plus” management group were significantly higher than those in routine management group [HPLP-IIC: (96.25±13.74) and (108.05±14.73) points, SF-36: (61.25±5.09) and (78.05±4.37) points, TASHP: (81.05±5.37) and (94.68±3.37) points] (all P<0.001), while systolic blood pressure (SBP) [(128.52±4.02) and (126.81±2.34) mmHg (1 mmHg=0.133 kPa)] and diastolic blood pressure (DBP) [(81.84±6.32) and (79.37±4.25) mmHg] were significantly lower than those in routine management group [SBP: (133.09±5.16) and (133.35±2.57) mmHg, DBP: (85.68±7.15) and (86.05±5.37) mmHg](all P<0.001). And, decrease of SBP [6 months: (-4.43±1.19) and (-6.14±2.01) mmHg] and DBP [6 months: (-3.75±1.71) and (-6.22±2.38) mmHg] in “Internet plus” management group were significantly higher than those in routine management group [SBP: (-1.28±0.75) and (-1.02±0.26) mmHg; DBP: (-1.05±0.62) and (-0.68±0.29) mmHg](all P<0.001). Conclusion:The “Internet plus” management based on AISAS mode can control blood pressure by improving the lifestyle, compliance and quality of life of young and middle-aged hypertensive patients.

Objective:To assess the correlation and consistency between the cancer risk-oriented endoscopic Kimura-Takemoto classification and the operative link for gastritis assessment (OLGA) in risk stratification of gastric cancer in patients with chronic gastritis after Helicobacter pylori ( H. pylori) eradication. Methods:From January 1, 2018 to October 31, 2021, 97 patients with chronic gastritis who successfully underwent H. pylori eradication at Beijing Friendship Hospital affiliated to Capital Medical University were selected. During the follow-up period, all patients underwent standardized magnifying endoscopy to assess gastric mucosal atrophy with the Kimura-Takemoto classification, which was classified as no or mild atrophy, moderate atrophy, and severe atrophy. Additionally, according to the new Sydney staging system, endoscopic biopsies were conducted at 5 sites of the patients to classify into OLGA stages 0, Ⅰ, Ⅱ, Ⅲ, or Ⅳ. Spearman rank correlation analysis and Kappa consistency test were performed to evaluate the correlation and consistency between the 2 evaluation systems, respectively. Area under the curve (AUC) of the receiver operating characteristic curve was used to calculate the predictive ability of the grading of gastric mucosal atrophy under endoscopy in high-risk histological staging. Furthermore, multivariate logistic regression analysis was used to assess factors influencing the consistency of the 2 evaluation systems. Chi-square test or Fisher′s exact test were used for statistical analysis. Results:Longitudinal follow-up was completed in 97 cases, with a follow-up time of (37.38±13.18) months after H. pylori eradication. The proportion of OLGA stage Ⅲ to Ⅳ in patients with no or mild atrophy (21.7%, 10/46) was lower than that in patients with moderate and severe atrophy (63.0%, 29/46 and 5/5, respectively), and the differences were statistically significant( χ2=16.07 and 13.30, both P<0.001). However, there was no significant difference in distribution of OLGA staging between patients with moderate atrophy and patients with severe atrophy (all P>0.05). The consistency rate of high-risk assessment for gastric cancer between the 2 evaluation systems was 73.2% (71/97). The correlation between the Kimura-Takemoto classification and OLGA staging was moderate ( r=0.47, 95% confidence interval(95% CI) 0.30 to 0.61, P<0.001). The result of consistency test indicated that the consistency of the 2 evaluation systems was moderate, and the Kappa value was 0.46 (95% CI 0.29 to 0.64, P<0.001). For patients with chronic gastritis after H. pylori eradication, the sensitivity of Kimura-Takemoto classification of moderate to severe atrophy under endoscopy in identifying high-risk of OLGA stages was 77.21% (95% CI 62.16% to 88.53%), the specificity was 69.81% (95% CI 55.66% to 81.66%), and the AUC was 0.735 (95% CI 0.636 to 0.820, P<0.01). As the time after H. pylori eradication increased (post- H. pylori eradication less than 18, 18 to 36, and more than 36 months), the consistency of atrophy assessment between the Kimura-Takemoto classification and OLGA staging reduced (7/8, 84.4% (27/32), 64.9% (37/57), respectively), and the difference was statistically significant ( χ2=4.36, P=0.037). The result of multivariate logistic regression analysis revealed that the time after H. pylori eradication more than 36 months ( OR=3.443, 95% CI 1.117 to 10.614, P=0.031) and gastric ulcer ( OR=3.928, 95% CI 1.177 to 13.110, P=0.026) were independent factors influencing the consistency between the Kimura-Takemoto classification and OLGA staging. Conclusions:The endoscopic and histological changes of chronic gastritis after eradication of H. pylori are consistent. Within short period after H. pylori eradication (no more than 36 months), the sensitivity of high-risk classification under endoscopy is high and the specificity is moderate, which can predict high-risk histological staging to a certain degree.

Objective:To compare the efficacy and safety of ticagrelor tablets produced by Zhejiang Hisun Pharmaceutical Co., Ltd. (the generic drug) and ticagrelor tablets produced by AstraZeneca Pharmaceutical Co., Ltd. (the original drug) in antiplatelet therapy.Methods:The study design was a retrospective cohort study. The subjects were patients who underwent percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) and postoperative antiplatelet therapy with ticagrelor tablets at First Affiliated Hospital of Dalian Medical University during January 2020 to July 2021. Through the hospital electronic medical record system, relevant clinical data of patients (age, gender, comorbidities, blood lipid level on admission, PCI indications, antiplatelet treatment regimen, efficacy and safety assessment endpoint events within 12 months of treatment, etc.) were collected. The patients were divided into the generic drug group and the original drug group. To exclude confounders, propensity score matching (PSM) method was used. The efficacy evaluation index was the incidence of the primary endpoint events (cardiogenic death, stroke, target revascularization, recurrent infarction) and secondary endpoint events (all-cause mortality, peripheral artery occlusion, stent thrombosis, angina attacks) within 12 months of treatment. The safety evaluation index was the incidence of bleeding event within 12 months of treatment.Results:A total of 1 486 patients were included in this study, including 734 in the generic drug group and 752 in the original drug group. The proportion of women and unstable angina, and the level of high-density lipoprotein cholesterol were higher than those in the original drug group (all P<0.05). The proportion of patients with hyperlipidemia and ST-segment elevation myocardial infarction were lower than those in the original drug group (both P<0.05). After PSM, 690 patients were enrolled in the generic drug group and 690 patients in the original drug group (all P>0.05). No differences in the comparison of clinical features between the 2 groups was significant (all P>0.05). No differences in the incidences of primary endpoints, secondary endpoints, and bleeding events between the 2 groups was significant before and after PSM [before PSM: 12.1%(89/734) vs. 10.9%(82/752), 10.8%(79/734) vs. 8.4%(63/752), 0.3%(2/734) vs. 0.5%(4/752); after PSM: 12.6%(87/690) vs. 12.3%(85/690), 11.0%(76/690) vs. 8.3%(57/690), 0.3%(2/690) vs. 0.4%(3/690); all P>0.05]. No death occurred in patients of both groups. Bleeding is predominantly characterized by epistaxis and subcutaneous petechiae, which did not lead to interruption of antiplatelet therapy. Conclusion:The efficacy and safety of ticagrelor tablets produced by Zhejiang Hisun Pharmaceutical Co., Ltd. for antiplatelet therapy in ACS patients after PCI surgery were basically the same as those of the original drug.
