ObjectiveTo investigate the potential targets of 2，5-dihydroxybenzoic acid （2，5-DHBA） in the treatment of metabolic dysfunction-associated fatty liver disease （MAFLD） and the molecular mechanism by which it regulates the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway. MethodsA network pharmacology analysis was performed at first， and related databases were used to obtain the common action targets of 2，5-DHBA and MAFLD， followed by molecular docking and pathway enrichment analysis to predict the potential biological processes and signaling pathways regulated by these targets. Then mouse normal hepatocytes AML-12 were used for cell experiments， and CCK-8 assay was used to determine the three optimal intervention concentrations of 2，5-DHBA. AML-12 cells were divided into control group， model group （cells cultured in a medium containing 2 mmol/L free fatty acid ［FFA］ to establish a cell model of MAFLD）， and three 2，5-DHBA intervention groups （cells cultured with FFA and 2，5-DHBA at the three different concentrations of 1.25， 5， and 20 μmol/L， respectively）. Oil red O staining was used to observe intracellular lipid accumulation； the fluorescent probe DCFH-DA was used to measure the level of intracellular reactive oxygen species （ROS）； biochemical assays were used to measure the content of triglyceride （TG） and total cholesterol （TC）； quantitative real-time PCR and Western Blot were used to measure the expression levels of related genes and proteins. A one-way analysis of variance was used for comparison between multiple groups， and the Tukey’s test was used for further comparison between two groups. ResultsA total of 32 common targets were obtained for 2，5-DHBA and MAFLD. Within a concentration range of 1.25 — 20 μmol/L， 2，5-DHBA treatment， starting from the concentration of 2.5 μmol/L， increased the viability of AML-12 cells in a dose-dependent manner. The minimum effective concentration of 1.25 μmol/L， the intermediate gradient concentration of 5 μmol/L， and the maximum safe concentration within the effective range of 20 μmol/L were selected for low-， middle-， and high-dose intervention， respectively. Compared with the model group， 2，5-DHBA intervention at concentrations of 1.25， 5， and 20 μmol/L could significantly reduce lipid droplet accumulation in cells （all P<0.05）， and there were significant differences in TG and TC between the model group and the three intervention groups （all P<0.05）. Compared with the control group， the model group had a significant increase in ROS fluorescence intensity （P<0.05）， and compared with the model group， there was a dose-dependent reduction in intracellular ROS level after treatment with 5 μmol/L or 20 μmol/L 2，5-DHBA （P<0.05）. Compared with the model group， 2，5-DHBA treatment at concentrations of 5 and 20 μmol/L significantly downregulated the mRNA expression levels of the lipogenic genes SREBf1 and FASN and upregulated the mRNA expression levels of the key antioxidant gene Nrf2 and its downstream target gene HO-1 （all P<0.05）. Compared with the control group， the expression of p-PI3K/PI3K and p-Akt/Akt in the model group was significantly increased （all P<0.05）. Compared with the model group， the protein expression levels of p-PI3K/PI3K and p-Akt/Akt were significantly decreased after 5 μmol/L 2，5-DHBA treatment （P<0.05）. Compared with the control group， the expression levels of Nrf2 and HO-1 protein in the model group were significantly decreased （all P<0.05）. The protein levels of Nrf2 and HO-1 were significantly increased after treatment with 1.25 μmol/L 2，5-DHBA （P<0.05）. ConclusionNetwork pharmacology and cellular experiments confirm that 2，5-DHBA can alleviate lipid deposition and oxidative stress by regulating the PI3K/Akt signaling pathway， thereby exerting a therapeutic effect on MAFLD.

Objective: To investigate the iodine nutrition status of children in water borne iodine excess areas in Hebei Province, so as to provide references for scientific prevention and control of water borne iodine excess hazards. Methods: From March to September each year during 2018 to 2023, a cross sectional survey was conducted in 39 water borne iodine excess counties (measured in 2017) from 5 cities (Cangzhou, Hengshui, Xingtai, Handan and Langfang) in Hebei Province. The survey included the detection of iodine content in residents drinking water, the measurement of thyroid volume in children aged 6-12, the detection of salt iodine and urinary iodine. The iodine nutrition status and water iodine distribution of 6-12 year-old children were evaluated from different perspectives such as years, gender, and age. Kruskal-Wallis H- test, Mann-Whitney U test and Chi square test were used for group comparison. Results: A total of 38 755 children were surveyed from 2018 to 2023, and 1 270 drinking water samples were tested across the province. The mass volume concentration of iodine in water showed a decreasing trend over the years ( Z= -30.87, P <0.01). Among 38 470 salt samples monitored from children s home, 24 790 were not non iodized salt, with a non iodized salt rate of 64.44%. A total of 31 989 urine samples were collected from children aged 8-10 years, with the median urine iodine was 245.94 μg/L. Comparing the results of urinary iodine in children from different years, the median urinary iodine from 2018 to 2023 were 328.0, 339.3, 267.8, 279.1, 291.3, 186.5 μg/L, respectively, with statistically significant differences ( H= 4 138.40 , P <0.01). Further pairwise comparisons showed that the median urinary iodine of children in 2023 was lower than in all other years ( Z =-51.59 to -11.41, all P <0.01). Among children aged 6-12 years, 1 150 cases of goiter were detected and the rate of goiter was 3.0%; and the goiter rates in boys and girls were 2.8% and 3.1%, with no significant difference between the sexes ( χ 2= 2.76, P >0.05). There were significant differences in the rate of goiter among different years and ages ( χ 2=324.02, 191.61, both P <0.05). Conclusions With the progress of water reform in water borne iodine excess areas of Hebei Province, children s iodine nutrition has reduced from excessive state to suitable state. It is necessary to continue to expand the coverage of water based iodine reduction projects, and strengthen the monitoring of iodine nutrition status of key populations in water borne iodine excess areas.

[Objective] To compare the efficacy and safety of deglycerolized red blood cells (DRBC) and suspended red blood cells (SRBC) based on the propensity score matching (PSM) method, so as to provide evidence for the rational use of DRBC resources in clinical practice. [Methods] A total of 89 patients who received DRBC transfusion and 2 916 patients who received SRBC transfusion in our hospital from January 2023 to September 2024 were included. A 1∶1 nearest neighbor PSM was used to balance covariates such as gender, age, and body mass index (BMI). The changes of hemoglobin (Hb), red blood cell (RBC) count, hematocrit (HCT), and inflammatory markers such as white blood cell (WBC) count, neutrophil (NE) count, C-reactive protein (CRP), and Interleukin-6(IL-6) in the last 72 hours after transfusion were analyzed by SPSS 26.0 and R software to evaluate clinical efficacy and transfusion safety. [Results] The baseline of the two groups was balanced after PSM (P>0.05). There was no significant difference in the total effective rate between the DRBC group (80.9%) and the SRBC group (86.5%) (P>0.05). In the SRBC group, WBC (×10 /L) increased from 9.634±6.742 to 10.147±6.835, CRP (mg/dL) increased from 5.468±4.647 to 6.174±6.114, and IL-6(pg/mL) decreased from 213.733±587.191 to 157.255±552.626. In the DRBC group, WBC (×10 /L) decreased from 11.123±7.880 to 11.011±8.549, CRP (mg/dL) decreased from 5.729±4.761 to 5.326±4.466, and IL-6(pg/mL) decreased from 238.806±639.060 to 152.255±266.558. Compared with the before treatment, the differences between the SRBC group and DRBC group were not statistically significant (P>0.05). Among all patients included in the statistics, the overall incidence of transfusion adverse reactions was 0.205% (6/2 916) in the SRBC group, and no adverse reactions occurred in the DRBC group. The incidence in the SRBC group was higher than that in the DRBC group. [Conclusion] Based on PSM analysis, there was no significant difference in the efficacy and safety of DRBC transfusion compared with SRBC transfusion, which can provide evidence-based support for routine application.

ObjectiveTo investigate the association between serum creatinine/cystatin C ratio （CCR） and nonalcoholic fatty liver disease （NAFLD） based on the NHANES database， and to evaluate the potential significance of CCR as an indicator reflecting the metabolic status of the body. MethodsBased on the data from the NHANES database in 1999‍ ‍—‍ ‍2004， a total of 4 217 participants were enrolled and divided into NAFLD group with 1 726 participants and non-NAFLD group with 2 491 participants. CCR was compared between the two groups， and the association between CCR and NAFLD was analyzed. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups. The multivariate logistic regression model was used to investigate the association between CCR and NAFLD； CCR was divided into 4 groups based on quartiles， and odds ratio （OR） and 95% confidence interval （CI） in the regression model was calculated with the first quartile as reference. In addition， the restricted cubic spline analysis was used to investigate whether there was a non-linear relationship between CCR and NAFLD， and interaction items were introduced into the Logistic regression model to perform an interaction analysis. Subgroup analyses were performed based on the stratification of variables to investigate the difference in the association between CCR and NAFLD in different populations. ResultsThe non-NAFLD group had a significantly higher CCR than the NAFLD group （Z=-4.76，P<0.01）. The Logistic regression analysis showed that in model 1 without adjustment of variables， CCR was negatively associated with NAFLD （OR=0.993，95%CI：0.989‍ ‍—‍ ‍0.996，P<0.01）， and in model 3 with adjustment of all variables， CCR was still negatively associated with NAFLD （OR=0.986，95%CI：0.981‍ ‍—‍ ‍0.991，P<0.01）. The analysis of CCR based on quartiles showed a significant association between the increase in CCR and the reduction in the risk of NAFLD. In model 3， compared with the individuals with the lowest quartile of CCR， the individuals with the highest quartile of CCR had a significantly lower risk of NAFLD （OR=0.426，95%CI：0.316‍ ‍—‍ ‍0.574，P<0.01）. Further interaction and subgroup analyses showed that the interaction between CCR and age/sex had a statistical significance （P_interaction<0.01 and P_interaction=0.04）. The subgroup analysis based on age showed a more significant association between CCR and NAFLD in the middle-aged population （≤60 years） （OR=0.982，95%CI：0.976‍ ‍—‍ ‍0.987）， and the subgroup analysis based on sex showed a stronger association between CCR and NAFLD in women （OR=0.979，95%CI：0.972‍ ‍—‍ ‍0.986）. ConclusionThis study shows a significant negative association between CCR and NAFLD， and such association is more significant in middle-aged individuals and women.

Retained products of conception (RPOC) represent a common pregnancy-related condition that may lead to complications such as abnormal uterine bleeding, infection, secondary arteriovenous fistula, intrauterine adhesions, and infertility. Currently, the main clinical treatments for RPOC include surgical intervention, medical therapy, and expectant management, sometimes supplemented by high-intensity focused ultrasound or uterine artery embolization when necessary. However, no standardized treatment guidelines exist. Medical and expectant management may help some patients avoid or reduce the need for surgery, though these approaches often involve a prolonged disease course. While surgery yields rapid results, patients with large lesions may require multiple procedures, increasing the risk of endometrial damage and intrauterine adhesions. There is still a lack of robust evidence-based guidance for selecting the optimal or individualized treatment approach. This review explores recent advances in the management of RPOC, with an emphasis on strategies that effectively preserve the endometrium, safeguard fertility, and support more precise, minimally invasive, and efficient personalized treatment.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease lacking effective therapy. Metformin, an antidiabetic medication, has shown promising therapeutic properties in preclinical fibrosis models; however, its precise cellular targets and associated mechanisms in fibrosis resolution remain incompletely defined. Most research on metformin's effects has focused on mesenchymal and inflammatory responses with limited attention to epithelial cells. In this study, we utilized Sftpc lineage-traced and Fgfr2b conditional knockout mice, along with BMP2/PPARγ and AMPK inhibitors, to explore metformin's impact on alveolar epithelial cells in a bleomycin-induced pulmonary fibrosis model and cell culture. We found that metformin increased the proliferation and differentiation of alveolar type 2 (AT2) cells, particularly the recently identified injury-activated alveolar progenitors (IAAPs)-a subpopulation characterized by low SFTPC expression but enriched for PD-L1. Single-cell RNA sequencing revealed a reduction in apoptosis among mature AT2 cells. Interestingly, metformin's therapeutic effects were not significantly affected by BMP2 or PPARγ inhibition, which blocked the lipogenic differentiation of myofibroblasts. However, Fgfr2b deletion in Sftpc lineage cells significantly impaired metformin's ability to promote fibrosis resolution, a process linked to AMPK signaling. In conclusion, metformin alleviates fibrosis by directly activating AT2 cells, especially the IAAPs, through a mechanism that involves AMPK and FGFR2b signaling, but is largely independent of BMP2/PPARγ pathways.

OBJECTIVE: To compare the efficacy and safety of intravenous colistin sulfate combined with nebulized inhalation versus intravenous monotherapy for pulmonary infections caused by carbapenem-resistant organism (CRO). METHODS: A multicenter retrospective cohort study was conducted. Clinical data were collected from patients admitted to the intensive care unit (ICU) of 10 tertiary class-A hospitals in Henan Province between July 2021 and May 2023, who received colistin sulfate for CRO pulmonary infections. Data included baseline characteristics, inflammatory markers [white blood cell count (WBC), neutrophil count (NEU), procalcitonin (PCT), C-reactive protein (CRP)], renal function indicators [serum creatinine (SCr), blood urea nitrogen (BUN)], life support measures, anti-infection regimens, clinical efficacy, microbiological clearance rate, and prognostic outcomes. Patients were divided into two groups: intravenous group (colistin sulfate monotherapy via intravenous infusion) and combination group ((intravenous infusion combined with nebulized inhalation of colistin sulfate). Changes in parameters before and after treatment were analyzed. RESULTS: A total of 137 patients with CRO pulmonary infections were enrolled, including 89 in the intravenous group and 48 in the combination group. Baseline characteristics, life support measures, daily colistin dose, and combination regimens (most commonly colistin sulfate plus carbapenems in both groups) showed no significant differences between two groups. The combination group exhibited higher clinical efficacy [77.1% (37/48) vs. 59.6% (52/89)] and microbiological clearance rate [60.4% (29/48) vs. 39.3% (35/89)], both P < 0.05. Pre-treatment inflammatory and renal parameters showed no significant differences between two groups. Post-treatment, the combination group showed significantly lower WBC and CRP [WBC (×10⁹/L): 8.2±0.5 vs. 10.9±0.6, CRP (mg/L): 14.0 (5.7, 26.6) vs. 52.1 (24.4, 109.6), both P < 0.05], whereas NEU, PCT, SCr, and BUN levels showed no significant between two groups. ICU length of stay was shorter in the combination group [days: 16 (10, 25) vs. 21 (14, 29), P < 0.05], although mechanical ventilation duration and total hospitalization showed no significant differences between two groups. CONCLUSIONS Intravenous colistin sulfate combined with nebulized inhalation improved clinical efficacy and microbiological clearance in CRO pulmonary infections with an acceptable safety profile.

Diabetes is a chronic disease that requires lifelong medication and long-term management. The longer the duration of the disease, the more likely it is to lead to progressive chronic complications affecting the eyes, kidneys, nervous system, and cardiovascular system. These complications may result in gradual functional decline or even organ failure, and may also trigger severe acute metabolic disorders. The cumulative financial burden on patients and their families can be substantial, giving rise to what is known as financial toxicity, which in turn may negatively affect patients' health outcomes. This review comprehensively explores the concept of financial toxicity in diabetic patients, including its assessment tools, influencing factors, and coping strategies. It also offers targeted suggestions aimed at informing the development of more scientific and effective systemic interventions, with the ultimate goal of improving treatment outcomes and quality of life for individuals living with diabetes.

Objectives:To preliminarily investigate the safety and efficacy of same-day discharge(SDD)following radiofrequency catheter ablation for arrhythmia.Methods:A total of 50 consecutive patients who underwent radiofrequency catheter ablation for arrhythmia in the SDD strategy at Fuwai Hospital from 8 July 2024 to 18 September 2024 were included in this analysis.The study evaluated the immediate success rate of the ablation,the rate of all-cause and arrhythmia-related readmission,outpatient or emergency visits and incidence of complications within 30 days post ablation,and recurrence rate of arrhythmias over a 3-month follow-up period.Results:The average age of the 50 patients was(47.2±16.1)years old,32 patients(64.0%)were male.Radiofrequency catheter ablation was performed in 47 patients(94.0%),including 18(36.0%)atrial fibrillation(AF)ablation.Three patients(6.0%)underwent electrophysiological study only.The immediate success rate for ablation patients was 100%(47/47).None of the patients developed vascular puncture-related or ablation-related complications.The average hospital stay and postoperative observation time were(6.84±1.13)hours and(3.40±1.12)hours,respectively.The all-cause and arrhythmia-related readmission,outpatient or emergency visits rates within 30 days were 12.0%(6/50)and 2.0%(1/50),respectively.Two patients(4.0%)post ablation experienced AF recurrence during the 3-months follow-up period.Conclusions:Radiofrequency catheter ablation for arrhythmias in SDD strategy is safe,effective,and feasible.
