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.

ObjectiveTo explore the mechanism of Hei Xiaoyaosan in improving the cognitive function in Alzheimer's disease （AD） from cell apoptosis mediated by the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/nuclear factor kappa B （NF-κB） signaling pathway. MethodsFour-month-old SD male rats were randomly assigned into a blank group， a sham group， a model group， a donepezil hydrochloride （0.45 mg·kg^-1） group， and high-， medium-， and low-dose （15.30， 7.65， and 3.82 g·kg^-1， respectively） Hei Xiaoyaosan groups， with 10 rats in each group. The sham group received bilateral hippocampal injection of 1 μL normal saline， while the other groups received bilateral hippocampal injection of 1 μL beta-amyloid 1-42 （Aβ_1-42） solution for the modeling of AD. Rats were administrated with corresponding agents once a day for 42 consecutive days. The Morris water maze test was carried out to assess the learning and memory abilities of rats. Hematoxylin-eosin staining was employed to observe pathological changes in the hippocampus of rats. Enzyme-linked immunosorbent assay was employed to measure the levels of cysteinyl aspartate-specific proteinase-3 （Caspase-3）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax）. Western blot was employed to determine the protein levels of PI3K， Akt， and NF-κB. A cell model of AD was established by co-culturing Aβ_1-42 and PC12 cells in vitro. Cell viability and apoptosis were detected by the cell-counting kit 8 （CCK-8） assay and flow cytometry （FC）， respectively. ResultsAnimal experiments showed that compared with the blank group， the model group had a prolonged escape latency （P<0.01）， a reduced number of crossing platforms （P<0.01）， disarrangement and a reduced number of hippocampal neurons， up-regulated expression of Bax and Caspase-3， down-regulated expression of Bcl-2 （P<0.01）， decreased p-PI3K/PI3K and p-Akt/Akt levels， and an increased p-NF-κB/NF-κB level （P<0.01）. Compared with the model group， donepezil hydrochloride and high- and medium-dose Hei Xiaoyaosan shortened the escape latency and increased the number of crossing platforms （P<0.05， P<0.01）， improved the arrangement and increased the number of hippocampal neurons， down-regulated the expression levels of Bax and Caspase-3， up-reguated the expression level of Bcl-2 （P<0.05， P<0.01）， increased the p-PI3K/PI3K and p-Akt/Akt levels （P<0.05， P<0.01）， and reduced the p-NF-κB/NF-κB level （P<0.05， P<0.01）. Cell experiments showed that compared with the blank group， the model group exhibited an increased apoptosis rate （P<0.01）. Compared with the model group， the serum containing Hei Xiaoyaosan at various doses improved the cell viability （P<0.01）， and the serum containing Hei Xiaoyaosan at the high dose decreased the cell apoptosis （P<0.01）. ConclusionHei Xiaoyaosan may improve the learning and memory abilities of AD model rats by regulating cell apoptosis， while increasing the vitality and reducing the apoptosis rate of AD model cells via the PI3K/Akt/NF-κB signaling pathway.

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.

Objective This study aimed to adapt the data-driven Palliative Care Outcomes Collaboration(PCOC)model to the local context and evaluate its feasibility and preliminary effectiveness in a palliative care unit in China,with the goal of informing its broader integration into national palliative care practice.Methods Based on international experience,a localized implementation protocol for the PCOC model was developed through expert con-sultations and a pilot study.The protocol incorporated key elements including organizational and managerial sup-port,team training and capacity building,information system integration,supervision and feedback mechanisms,pro-cess optimization,and data-driven decision-making.From June to December 2023,the protocol was piloted in the palliative care unit of a tertiary cancer hospital in Changsha,China.Implementation outcomes were assessed by comparing patients' urgent care response rates,symptom stability rates,and symptom improvement rates between the first 1～3 months and 4～6 months after implementation.Results During the study period,a total of 355 inpatients were enrolled,with the PCOC assessment achieving full coverage(100％)and a completion rate of 97.78％.There was no statistically significant difference in the urgent needs response rate between the first 1～3 months and the 4～6 months after the implementation of the PCOC model(P=0.533).However,compared to the first 1～3 months af-ter implementation,patients in the 4～6 months period showed significantly higher symptom stability rates for pain,psychological/spiritual issues,and family/caregiver problems,as well as a higher improvement rate for pain(P＜0.05).Conclusion The localized PCOC implementation protocol facilitates standardized assessment and symptom manage-ment,and its application can enhance the quality of palliative care.

OBJECTIVE To investigate the relationship between kinesin superfamily(KIF)18B,20A and epithelial-mesenchymal transition(EMT)markers,clinicopathological features and prognosis in nasopharyngeal carcinoma.METHODS 116 cases of nasopharyngeal biopsy tumor tissues diagnosed as nasopharyngeal carcinoma in Department of Otolaryngology,Yulin Traditional Chinese Medicine Hospital from July 2017 to May 2019 were selected,nasal mucosa biopsy tissues of 116 chronic nasopharyngitis patients were used as control,the expression of KIF18B,KIF20A,and EMT markers epithelial calreticulin(E-cadherin),vimentin,twist in nasopharyngeal carcinoma tissues and nasopharyngeal chronic mucositis tissues were compared.The relationship between KIF18B,KIF20A expression and EMT marker expression and clinicopathological features in nasopharyngeal carcinoma tissues were analyzed.5 years after follow-up,the relationship between KIF18B,KIF20A expression and the prognosis of nasopharyngeal carcinoma patients were analyzed by the Kaplan-Meier method and multivariate Cox regression analysis.RESULTS The positive expression rates of KIF18B,KIF20A,Vimentin and Twist in nasopharyngeal carcinoma tissues were 55.17％,42.24％,20.69％,and 26.72％respectively,which were higher than 13.79％,9.48％,4.31％,and 5.17％in nasopharyngeal chronic mucosal inflammation tissues;The positive expression rate of E-cadherin in nasopharyngeal carcinoma tissues was 68.10％,which was lower than 91.38％in nasopharyngeal chronic mucosal inflammation tissues(P<0.05).KIF18B and KIF20A were negatively correlated with E-cadherin expression(rs=-0.439,-0.432,P<0.05),KIF18B,KIF20A were positively correlated with Vimentin(rs=0.418,0.456,P<0.05)and Twist(rs=0.427,0.427,P<0.05).The KIF18B and KIF20A positive expression rates in patients with low differentiation,lymph node metastasis,TNM stage Ⅲ-Ⅵa,clinical efficacy stable disease(SD)/progressive disease(PD)were higher than those in patients with high differentiation,no lymph node metastasis,stage Ⅰ-Ⅱ,and complete response(CR)/partial response(PR)(P<0.05).4 patients were lost to 5 years after follow-up,the success rate of follow-up was 96.55％(112/116),31 patients died,and the 5-year overall survival rate was 72.32％(81/112).The 5-year cumulative survival rate in KIF18B and KIF20A positive expression nasopharyngeal carcinoma patients were lower than those in KIF18B and KIF20A negative expression nasopharyngeal carcinoma patients(P<0.05).TNM stage Ⅲ-Ⅵa(HR=1.154,95％CI:1.018-1.308),clinical efficacy SD/PD(HR=1.287,95％CI:1.132-1.654),KIF18B(HR=1.823,95％CI:1.332-2.493)and positive expression of KIF20A(HR=2.110,95％CI:1.460-3.051)were independent risk factors affecting the prognosis of nasopharyngeal carcinoma patients(P<0.05).CONCLUSION KIF18B and KIF20A are abnormally highly expressed in nasopharyngeal carcinoma tissues,the positive expression of the two are closely related to EMT,tumor malignant progression and prognosis,and KIF18B,KIF20A positive expression patients have shorter survival time.

Acute respiratory distress syndrome (ARDS) is the leading cause of respiratory failure with high morbidity and mortality. Pulmonary surfactant (PS)-based complementary therapies have exhibited potential for ARDS healing and applied as an adjunctive therapy strategy. Coacervate (Coac) has the characteristics of softness, deformability and excellent molecular enrichment properties, and has attracted extensive attention in the biomedical field. Here PS and coacervate were combined for the potential ARDS treatment. The Coac, fabricated from polyallylamine hydrochloride (PAH) and adenosine triphosphate (ATP) by simple mixing, exhibited soft droplet property and high enrichment for dexamethasone sodium phosphate (DSP). To avoid the fusion effect of membraneless coacervate and endow it with biological functions of PS, liposomes with PS-biomimetic lipid components (PS-lipo) were further introduced to construct PS-biomimetic membranized coacervate (DSP@PS-Coac). The DSP@PS-Coac demonstrated high lung targeting effect and significant penetration efficiency after intravenous injection. Furthermore, PS-lipo replenished the endogenous PS pool and facilitated the distribution of DSP in inflammatory cells in the lung. In the ARDS mouse model, PS-Coac and DSP exerted synergetic anti-inflammatory functions, via reducing the recruitment of inflammatory neutrophils and modulating macrophages into anti-inflammatory phenotype. The overall results confirmed that DSP@PS-Coac may provide a promising delivery option for the treatment of ARDS.
