ObjectiveTo investigate the effects of Hei Xiaoyaosan on neuroinflammation in APP/PS1 mice and decipher the mechanism based on the C-X3-C chemokine ligand 1 （CX3CL1）-CX3CL1 receptor 1 （CX3CR1） signaling axis. MethodsSixty 16-week-old male APP/PS1 mice were selected and acclimatized for one week， and they were then randomly allocated into a model group， a CX3CL1 group （bilateral hippocampal injection of CX3CL1 at 0.5 g·L^-1）， and high-， medium-， and low-dose （22.10， 11.05， and 5.53 g·kg^-1， respectively） Hei Xiaoyaosan groups， with 12 mice in each group. Twelve age-matched male C57BL/6J mice served as the blank group （bilateral hippocampal injection of an equal volume of PBS）. The high-， medium-， and low-dose Hei Xiaoyaosan groups received corresponding drugs via gavage， while the blank group received an equal volume of normal saline， with an intervention period of 90 days. Morris water maze was used to assess learning and memory abilities. Nissl staining was performed to observe the pathological changes in neurons of the hippocampal CA1 region. Immunohistochemistry was adopted to detect amyloid-β_1-42 （Aβ_1-42） deposition in the hippocampal CA1 region. The immunofluorescence assay was employed to detect the expression of M1 and M2 microglial markers， including cluster of differentiation 86 （CD86）/ionized calcium-binding adapter molecule 1 （Iba-1） and arginase-1 （Arg1）/Iba1. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of interleukin-8 （IL-8） and interleukin-13 （IL-13） in the hippocampal tissue. Western blot was employed to determine the protein levels of CX3CL1， CX3CR1， CREB-binding protein （CBP）， cyclic AMP response element-binding protein （CREB）， phosphorylated （p）-CREB， and brain-derived neurotrophic factor （BDNF） in the hippocampal tissue. ResultsCompared with the blank group， the model group exhibited prolonged escape latency on day 5 and a reduced swimming distance in the target quadrant （P<0.01）， disarrangement of hippocampal neurons， with a reduced number of cells and uneven Nissl body staining， increased CD86/Iba1 expression， decreased Arg1/Iba1 expression （P<0.01）， enhanced Aβ expression （P<0.01）， an elevated IL-8 level and a declined IL-13 level （P<0.01）， and downregulated protein levels of CX3CL1， CX3CR1， CBP， p-CREB， and BDNF （P<0.01）. Compared with the model group， all treatment groups showed shortened escape latency on day 5 and an increased swimming distance in the target quadrant （P<0.05， P<0.01）， regular arrangement of neurons with an increased number and increased Nissl bodies， reduced CD86/Iba1 expression， increased Arg1/Iba1 and decreased Aβ expression （P<0.01）， and a declined IL-8 level and an elevated IL-13 level （P<0.05， P<0.01）. In the CX3CL1 group and the high- and medium-dose Hei Xiaoyaosan groups， the relative expression levels of CX3CL1， CX3CR1， CBP， and p-CREB were upregulated （P<0.01）. In the low-dose Hei Xiaoyaosan group， the relative expression levels of CX3CL1， CX3CR1， CBP， p-CREB/CREB， and BDNF were upregulated （P<0.05， P<0.01）. ConclusionHei Xiaoyaosan can improve learning and cognitive abilities in APP/PS1 mice. Specifically， it may regulate the CX3CL1/CX3CR1 signaling axis to activate the CREB/BDNF signaling pathway for the subsequent release of BDNF， modulation of microglial polarization， reduction of inflammatory cytokine levels， and attenuation of Aβ deposition.

Objective To evaluate the application of serum soluble suppression of tumorigenicity-2(sST2),glo-merular filtration rate(GFR),and serum iron(SI)combined test for predicting prognosis of acute decompensated heart failure(ADHF)patients.Methods A total of 575 ADHF patients were included in this study.Serum sST2,GFR,SI levels and other biomarkers were measured and followed up.Patients were divided into poor prognosis and good prognosis groups based on the occurrence of major adverse cardiovascular events(MACEs).Kaplan-Meier survival analysis and Cox regression analysis were used to evaluate the prognostic value of these indicators,and receiver operating characteristic(ROC)curves were employed to compare the prediction outcome of single and combined indicators.Results In the poor prognosis group,heart rate,systolic blood pressure,diastolic blood pres-sure and fasting blood glucose level were all significantly higher than in those in the control group(P＜0.05).Ad-ditionally,the poor prognosis group had higher level of sST2 and total iron-binding capacity,while GFR,SI and transferring saturation were lower as compared to control group(P＜0.05).Cox multivariate survival analysis showed that sST2,GFR,and SI were independent predictors of poor prognosis in ADHF patients(P＜0.05).Kaplan-Meier survival analysis revealed that higher level of sST2 was associated with poor survival prognosis.ROC curve analysis showed that when the biomarkers like sST2,GFR and SI were used together,the area under the curve(AUC)in-creased to 0.834,with a sensitivity of 80.2%and a specificity of 75.6%.Conclusions Combination test of serum sST2,GFR and SI significantly supports the predictive function for ADHF patients'prognosis.The highest AUC val-ue from the combined biomarker prediction may contribute to a more accurate assessment of patient risk.This com-bined test of indicators provides a more reliable tool for clinicians in terms of early identification of high-risk pa-tients,guiding treatment decisions and improving the prognosis management of patients.

Objective To discuss the clinical efficacy of catheter-directed thrombolysis(CDT)in treating acute pulmonary embolism(APE).Methods A total of 215 patients with APE,who were admitted to the Second Affiliated Hospital of Shandong First Medical University of China,were enrolled in this study.Pulmonary angiography was performed in all the patients.After the location of the thrombus was identified,the pigtail catheter was rotated so as to break the thrombus into small pieces,which was followed by local infusion of thrombolytic agent urokinase to make recanalization of the occluded pulmonary artery.The postoperative clinical symptoms,blood oxygen saturation,mean pulmonary artery pressure,BNP,D-dimer,RV/LV diameter ratio were compared with their preoperative values.PESI scoring was used to evaluate the severity of the pulmonary embolism.Patients with PESI grade-Ⅲ and PESI grade-Ⅳ were classified into medium-risk group,and patients with PESI grade-V were classified into higher-risk group.Results Symptom relief immediately after surgery was observed in 210 patients,complete recanalization of pulmonary artery was achieved in 200 patients,and partial recanalization of pulmonary artery was seen in 15 patients.The preoperative mean pulmonary artery pressure,blood oxygen saturation,BNP,D-dimer,RV/LV diameter ratio were(46.24±5.32)mmHg,(90.36±3.23)％,(8 000.12±750.56)pg/mL,(7.5±2.3)mg/L and(1.63±0.22)respectively;at one week after surgery the above indicators were(26.12±3.36)mmHg,(98.74±2.12)％,(240.35±33.52)pg/mL,(1.75±0.36)mg/L and(1.11±0.13)respectively;the differences were statistically significant(all P＜0.05).In the patients who had symptoms of hemoptysis,shock and syncope before surgery,all these symptoms were completely disappeared in one week after CDT,and the symptoms of dyspnea,chest pain,and palpitations were significantly relieved after CDT,the differences were statistically significant(all P＜0.05).The difference in survival time between different PESI grade groups was statistically significant(P＜0.05).No serious postoperative complications such as severe arrhythmia,cerebral hemorrhage,or gastrointestinal bleeding occurred.Postoperative 3-month CT pulmonary angiography(CTPA)showed that the main pulmonary artery was well visualized and no thrombus-produced filling defect shadow was detected.Conclusion For the treatment of APE,CDT can promptly and rapidly open the obstructed pulmonary artery lumen,restore pulmonary artery hemodynamics,and correct hypoxemia.Therefore,CDT is a safe,effective and quick treatment for APE.

Objective To investigate the factors affecting the occurrence of new postoperative cardiac complications in patients undergoing esophageal cancer surgery with concomitant coronary heart disease. Methods Clinical data of patients who underwent esophageal cancer surgery with coronary heart disease at the Affiliated Huai'an No.1 People's Hospital of Nanjing Medical University from December 2019 to June 2023 were collected. Patients were divided into two groups based on whether they experienced postoperative cardiac complications. Using the occurrence of cardiac complications as the dependent variable, a multivariate logistic regression model was established to identify related influencing factors. Results A total of 223 patients were included, comprising 148 males and 75 females, with an average age of (71.78±6.31) years (range 53-88 years). Seventy-one (31.84%) patients experienced at least one new cardiac complication postoperatively, including 2 acute coronary syndrome, 13 heart failure, and 59 new-onset postoperative arrhythmias. Univariate analysis showed that age, systemic immune-inflammation index, pulmonary infection, need for invasive mechanical ventilation due to respiratory failure, acute respiratory distress syndrome (ARDS), acute delirium, pleural effusion requiring drainage, and acute renal failure were risk factors for postoperative new-onset cardiac complications (all P<0.05). Multivariate logistic regression analysis identified age, postoperative length of hospital stay, ARDS, and systemic immune-inflammation index as independent risk factors for new cardiac complications in esophageal cancer patients with coronary heart disease. Conclusion Strengthening perioperative management of esophageal cancer patients, ranging from preoperative evaluation to postoperative complication treatment, is crucial. Particular attention should be paid to age, ARDS, and other indicators to improve postoperative prognoses in patients with coronary heart disease complicated by esophageal cancer.

Objective: To evaluate the effects of a multidisciplinary weight management intervention, so as to provide a reference for the formulation of overweight and obesity intervention measures. Methods: From April to September 2025, overweight and obese residents aged 18-60 years who participated in a weight loss competition at the Health Management Center of Beilun People's Hospital in Ningbo City were selected as study subjects. They were divided into a control group and an intervention group. The control group received conventional weight management, while the intervention group received the multidisciplinary integrated weight management in addition to the conventional weight management, for a total intervention period of 8 weeks. Weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio, fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and blood pressure were collected before and after the intervention through physical examinations and laboratory tests. The generalized estimating equations (GEE) method was employed to analyze the differences in indicators between the two groups before and after the intervention. Results: The control group comprised 241 participants, including 161 females (66.80%), with a mean age of (35.66±7.80) years. The intervention group consisted of 127 participants, including 86 females (67.72%), with a mean age of (36.80±7.05) years. No statistically significant differences were observed between the two groups at baseline in terms of age, gender, weight, BMI, or waist-to-hip ratio (all P>0.05). Results from the GEE analysis indicated significant interactions between group and time for weight, BMI, waist circumference, and hip circumference (all P<0.05) with greater reductions in these parameters observed in the intervention group compared to the control group before and after the intervention. Similarly, significant interactions between group and time were observed for FBG, TG, TC, and LDL-C (all P<0.05), with the intervention group demonstrating larger decreases in these markers compared to the control group. However, no statistically significant interactions between group and time were observed for waist-to-hip ratio, HDL-C, systolic blood pressure, and diastolic blood pressure (all P>0.05). Following the intervention, a weight loss exceeding 10% was achieved by 13 participants (5.39%) in the control group and 62 participants (48.82%) in the intervention group. The proportion of individuals with a weight loss exceeding 10% was significantly higher in the intervention group compared to the control group (P<0.05). Conclusion Compared to conventional weight management, multidisciplinary integrated weight management demonstrated greater efficacy in improving weight-related indicators and blood glucose, blood lipids, and enhancing weight loss outcomes among overweight and obese residents.

Five previously undescribed diterpenoids, named succipenoids D‒H (1‒5), along with four undescribed lignans, named succignans A‒D (6‒9), were isolated from the dichloromethane extract of Chinese medicinal succinum. Compounds 1‒5 were characterized as nor-abietane diterpenoids, while compounds 6‒9 were identified as lignans polymerized from two groups of phenylpropanoid units. The structures of these novel compounds, including their absolute configurations, were determined through spectroscopic and computational methods. Biological assessments of renal fibrosis demonstrated that compounds 6 and 7 effectively reduce the expression of proteins associated with renal fibrosis, including α-smooth muscle actin (α-SMA), collagen I, and fibronectin in transforming growth factor-β1 (TGF-β1) induced normal rat kidney proximal tubular epithelial cells (NRK-52e).

Objective:To investigate the correlation between vitamin D levels and thyroid hormone sensitivity in euthyroid individuals.Methods:This cross-sectional study included 5 894 euthyroid individuals who underwent health examinations at the Department of Health Management, Peking Union Medical College Hospital, from December 2023 to February 2024. Thyroid feedback quantile-based index (TFQI), TSH index (TSHI), thyrotroph thyroxine resistance index (TT4RI), and the ratio of free triiodothyronine (FT3)/free thyroxine (FT4) were calculated to assess thyroid hormone sensitivity. Participants were categorized into vitamin D deficiency and non-deficiency groups based on serum 25(OH)D levels. The differences in thyroid hormone sensitivity indices and other clinical characteristics between the two groups were compared. Multivariate logistic regression models were used to analyze the association between vitamin D levels and thyroid hormone sensitivity, and stratified analysis was conducted to explore the association in different genders.Results:Among the study participants, 4 731 (80.3%) had vitamin D deficiency. Compared with the non-deficient group, the deficient group had a lower TFQI (-0.03(-0.31, 0.23) and -0.01(-0.28, 0.27)) ( Z=-2.130, P=0.033) and a higher FT3/FT4 ratio ((0.36±0.04) and (0.35±0.04)) ( t=-4.592, P<0.001). After adjusting for confounding factors including gender and age, the risk of impaired central and peripheral thyroid hormone sensitivity significantly increased in the non-deficient group (TFQI ( OR=1.16, 95% CI: 1.01-1.34); FT3/FT4 ( OR=1.23, 95% CI: 1.05-1.45)) (all, P<0.05). Conclusion:In euthyroid individuals, people with higher vitamin D levels have a higher risk of impaired thyroid hormone sensitivity.

Objective:To understand the current situation of hypertension in maintenance hemodialysis (MHD) for patients with diabetic kidney disease (DKD), and analyze the influencing factors of hypertension.Methods:A retrospective analysis was conducted on the data of 398 DKD patients who underwent MHD in Nanjing Gaochun People's Hospital and Nanjing Gaochun Hospital of Traditional Chinese Medicine from September 2022 to October 2024. The patients were assigned into hypertension group and control group based on presence or absence of hypertension. General information, dialysis parameters, and pre-dialysis laboratory indicators were collected and compared between two groups. Logistic regression model was performed to screen the influencing factors of hypertension in hemodialysis patients.Results:Among 398 DKD patients undergoing dialysis, 59 cases developed hypertension, with an incidence rate of 14.82%. The proportion of dialysis time<5 years, pre-dialysis systolic blood pressure (SBP), proportion of dialysate Ca 2+ concentration of 1.75 mmol/L, erythropoietin (EPO) usage, pre-dialysis Hcy and pre-dialysis blood phosphorus in hypertension group were higher than those in control group: 72.88% (43/59) vs. 54.28% (184/339), (129.57 ± 8.23) mmHg (1 mmHg = 0.133 kPa) vs. (133.79 ± 9.85) mmHg, 66.10% (39/59) vs. 43.36% (147/339), (4 062.71 ± 597.24) U/week vs. (2 748.36 ± 551.85) U/week, (20.09 ± 3.47) μmol/L vs. (16.81 ± 2.85) μmol/L, (2.45 ± 0.49) mmol/L vs. (2.27 ± 0.41) mmol/L ( P<0.05). Logistic regression analysis revealed that dialysis time<5 years ( OR = 2.479, 95% CI 1.281 to 4.799), dialysate Ca 2+ concentration of 1.75 mmol/L ( OR = 3.112, 95% CI 1.749 to 5.537), high EPO usage ( OR = 3.078, 95% CI 1.716 to 5.520), high pre-dialysis Hcy ( OR = 2.809, 95% CI 1.497 to 5.270), and high pre-dialysis blood phosphorus ( OR = 2.651, 95% CI 1.424 to 4.935) were risk factors for hypertension during dialysis in DKD patients ( P<0.05). Conclusions:DKD patients have a higher risk of developing hypertension during dialysis, especially those with dialysis time<5 years, dialysate Ca 2+ concentration of 1.75 mmol/L, high EPO usage, high pre-dialysis Hcy and blood phosphorus. Therefore, corresponding preventive measures should be implemented based on above factors in clinical practice to reduce the risk of hypertension.

Objective To investigate the compliance of hormone receptor-positive breast cancer patients with prolonged endocrine therapy and analyze its influencing factors.Methods This study was a retrospective cohort study.A total of 347 patients with breast cancer who received prolonged endocrine therapy in our hospital from June 2017 to March 2023 were selected.Relevant data of the patients were collected and they were divided into two groups according to whether they adhered to prolonged endocrine therapy:the compliance group and the non-compliance group.Using the x2 test to analyze the impact of patients'disease-related data on prolonging compliance with endocrine therapy.Use Logistic regression to analyze its influencing factors.Results Among 347 breast cancer patients who received extended endocrine therapy,during the median follow-up of 28 months(ranging from 12 to 60 months),319 patients(91.9％)adhered to extended endocrine therapy(compliance group),and their treatment compliance was acceptable.Twenty-eight cases(8.1％)of patients did not adhere to prolonged endocrine therapy(non-compliance group).Multivariate analysis showed that the independent factors Influencing the compliance of breast cancer patients with prolonged endocrine therapy were comorbidities and radiotherapy(P＜0.05).Conclusion Based on the characteristics of influencing factors,behavioral interventions such as increasing follow-up frequency and strengthening health education content can be implemented for some patients without comorbidities and those who have not received radiation therapy,and to improve treatment compliance.
