ObjectiveTo investigate the effect of schisanlactone E in ameliorating neuroinflammation and synaptic injury in APP/PS1 mice and to elucidate whether its mechanism is related to the regulation of helper T cell 17 (Th17)/regulatory T cell (Treg) immune balance. MethodsAPP/PS1 transgenic mice were assigned into model, low- and high-dose (2 mg·kg-1·d-1 and 4 mg·kg-1·d-1, respectively) schisanlactone E, and donepezil (1 mg·kg-1·d-1) groups. C57BL/6J mice were used as the control group. Each group received the corresponding drug by gavage for 30 days. Learning and memory abilities were assessed by the Morris water maze and novel object recognition tests. The percentages of Th17 and Treg cells in the peripheral blood were analyzed by flow cytometry. The mRNA levels of retinoid-related orphan receptor γt (RORγt), interleukin (IL)-17A, forkhead box protein 3 (FoxP3), and IL-4 in the hippocampus were determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The synaptic ultrastructure in the hippocampus was observed by transmission electron microscopy. The protein levels of synapsin Ⅰ and postsynaptic density protein 95 (PSD95) in the hippocampus were measured by Western blot. Aβ aggregation and microglial activation in the hippocampus were observed by immunofluorescence staining. The mRNA levels of tumor necrosis factor (TNF)-α, IL-6, and IL-1β in the hippocampus were determined by Real-time PCR. ResultsCompared with the control group, the model group showed prolonged escape latency (P<0.05), decreased time spent in the target quadrant, platform crossings, novel object exploration time, and percentage of novel object contact frequency (P<0.05, P<0.01), increased Aβ aggregation in the hippocampal tissue (P<0.01), an increased proportion of Th17 cells (P<0.05), a decreased proportion of Treg cells (P<0.05), and an increased Th17/Treg ratio (P<0.01) in the peripheral blood. Furthermore, the hippocampal tissue in the model group exhibited upregulated mRNA levels of RORγt and IL-17A (P<0.05, P<0.01), downregulated mRNA levels of FoxP3 and IL-4 (P<0.01), decreased synapses (P<0.05), decreased PSD density, synaptic interface curvature, and active zone length (P<0.05, P<0.01), and increased synaptic cleft width (P<0.05), downregulated protein levels of Synapsin Ⅰ and PSD95 (P<0.01), increased microglial activation (P<0.01), and upregulated mRNA levels of TNF-α, IL-6, and IL-1β (P<0.05). Compared with the model group, the high-dose schisanlactone E group and the donepezil group exhibited shortened escape latency and increased time in the target quadrant and platform crossings (P<0.05, P<0.01). The schisanlactone E groups and the donepezil group showed increased novel object exploration time (P<0.05, P<0.01) and percentage of novel object contact frequency (P<0.05, P<0.01), and reduced hippocampal Aβ aggregation (P<0.05, P<0.01). The schisanlactone E groups showed a decreased proportion of Th17 cells (P<0.05) and an increased proportion of Treg cells (P<0.05) in the peripheral blood, and all treatment groups showed a decreased Th17/Treg ratio (P<0.05, P<0.01). The high-dose schisanlactone E group showed a downregulated mRNA level of RORγt in the hippocampal tissue (P<0.05), and all treatment groups showed a downregulated mRNA level of IL-17A (P<0.05, P<0.01), and upregulated mRNA levels of FoxP3 and IL-4 (P<0.05, P<0.01). The schisanlactone E groups and the donepezil group showed increased synapses, active zone length, synaptic interface curvature, and PSD density, decreased synaptic cleft width (P<0.05, P<0.01), and upregulated protein levels of synapsin Ⅰ and PSD95 (P<0.05, P<0.01). The high-dose schisanlactone E group and the donepezil group showed decreased microglial activation in the hippocampus (P<0.01). The schisanlactone E groups and the donepezil group showed downregulated mRNA levels of TNF-α, IL-6, and IL-1β in the hippocampal tissue (P<0.05, P<0.01). ConclusionSchisanlactone E significantly improves the cognitive function in APP/PS1 mice by regulating the Th17/Treg immune balance, inhibiting neuroinflammation, and ameliorating synaptic injury.

ObjectiveTo observe the effect of aspirin curcumin ester (CA) on the activation and glucose metabolism reprogramming of the mouse microglia (BV2) model of inflammation induced by high glucose/β-amyloid (Aβ)1-42, and to explore the potential mechanism of CA in reducing neuroinflammatory response in the brain. MethodsThe BV2 activation model was constructed by high glucose combined with Aβ1-42 oligomers. BV2 cells were treated with Aβ1-42 oligomers (10 μmol·L-1) in a high glucose (50 mmol·L-1) environment and allocated into normal, high glucose, Aβ, and high glucose + Aβ groups. The cell morphology of each group was observed under a bright field. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was adopted to assess the mRNA levels of inflammatory factors including tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) as well as glycolysis-related glucose transporter type 1 (GLUT1), hexokinase 2 (HK2), phospofructokinase-2/fructose-2,6-bisphosphatase 3 (PFKFB3), and pyruvate kinase M2 (PKM2). To reveal the effects of CA on inflammatory response and glucose metabolism in BV2 cells exposed to high glucose/Aβ1-42, this study established the BV2 cell model of inflammatory activation by high glucose and Aβ1-42 oligomer intervention. The cells were allocated into normal, model (50 mmol·L-1 glucose + 10 μmol·L-1 Aβ1-42), CA (10 μmol·L-1), 2DG (0.2 mmol·L-1), and DADA (1 mmol·L-1) groups. Cell counting kit-8 (CCK-8) was used to detect cell survival rate. The cell morphology of each group was observed under a bright field. The expression of inflammatory factors TNF-α, IL-6, and IL-1β and glycolysis-related key enzymes GLUT1, HK2, PFKFB3, and PKM2 at the mRNA level in each group was measured by real-time PCR. The protein levels of GLUT1, HK2, PFKFB3, and PKM2 were determined by Western blot. The glycolysis rate in each group was measured by seahorse. LC-MS was employed to identify the glucose metabolism intermediates. The morphology of mitochondria in cells was observed by electron microscopy. ResultsConstruction of the BV2 cell model: Compared with the normal group, the Aβ group and the high glucose + Aβ group showed more amoeboid-shaped cells and cell aggregation. The high glucose + Aβ group exhibited increased the mRNA levels of TNF-α, IL-1β, and IL-6 (P<0.05, P<0.01), as well as those of key glycolytic enzymes GLUT1, HK2, PFKFB3, and PKM2 (P<0.01). The Aβ group also showed significantly increased mRNA levels of PKM2 and PFKFB3 (P<0.01). Effects of CA on the inflammatory response and glucose metabolism in BV2 cells exposed to high glucose/Aβ1-42: Compared with the normal group, the model group exhibited amoeboid-shaped cells and cell aggregation, upregulated mRNA levels of TNF-α, IL-1β, IL-6, iNOS, GLUT1, HK2, PFKFB3, and PKM2 (P<0.01) and protein levels of GLUT1, HK2, and PFKFB3 (P<0.05, P<0.01), an increased basal glycolysis rate (P<0.01), a decreased compensatory glycolysis rate (P<0.01), increased glycolytic intermediates and reduced TCA cycle intermediates. In addition, the mitochondria in the model group exhibited a decreased number (P<0.05), impaired crista integrity (P<0.01), an increased proportion of vacuolization (P<0.01), and abnormal mitochondrial morphology. Compared with those in the model group, the number of amoeboid-shaped BV2 cells reduced in the CA and 2DG groups, while most BV2 cells in the DADA group became elongated spindle-shaped. All the three treatment groups showed downregulated mRNA levels of TNF-α, IL-1β, IL-6, GLUT1, HK2, PFKFB3, and PKM2 (P<0.05, P<0.01), downregulated protein levels of GLUT1, HK2, and PFKFB3 (P<0.05, P<0.01), and slow compensatory glycolysis and basal glycolysis (P<0.05, P<0.01). Glycolytic intermediates were decreased and TCA cycle intermediates were increased in the CA and 2DG groups. Mitochondrial morphology largely returned to the normal level in all the three treatment groups, with an increase in mitochondrial number (P<0.05), improved crista integrity (P<0.05, P<0.01), and a decreased proportion of vacuolization (P<0.05). ConclusionAβ1-42 oligomers can activate BV2 cells and enhance glycolytic activity in the high glucose environment. CA can reduce the expression of inflammatory factors and inhibit the activation of BV2 cells by regulating the glucose metabolism reprogramming in BV2 cells.

ObjectiveTo investigate the effects of paeoniflorin (PF) on neuroinflammation and cognitive impairment in the rat model of Alzheimer's disease (AD) and to clarify whether its mechanism is associated with regulation of the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. MethodsGlycosides related to AD-associated neuroinflammation were screened through bibliometric analysis, and the potential targets of PF were predicted through network pharmacology and molecular docking. A rat model of AD was established by intraperitoneal injection of D-galactose (100 mg·kg-1·d-1). Rats were assigned into a control group, a model group, a PF (200 mg·kg-1) group, and a donepezil (0.5 mg·kg-1·d-1) group, and drugs were administered by gavage for 21 days. The learning and memory abilities were evaluated by the Morris water maze (MWM). Hematoxylin-eosin (HE) staining and Nissl staining were performed to observe hippocampal neuronal morphology. The mRNA levels of inflammatory factors were determined by Real-time quantitative polymerase chain reaction (Real-time PCR), and the protein levels of molecules in the JAK2/STAT3 signaling pathway were determined by Western blot. ResultsCompared with the control group, the model group showed prolonged escape latency and decreased platform crossings and time spent in the target quadrant (P<0.05, P<0.01), accompanied by increased expression of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α), as well as elevated ratios of phosphorylated (p)-JAK2/JAK2 and p-STAT3/STAT3 (P<0.01). Compared with the model group, the PF group and donepezil group exhibited shortened escape latency and increased platform crossings and time spent in the target quadrant (P<0.05, P<0.01), decreased expression levels of IL-1β and TNF-α, upregulated mRNA levels of interleukin-4 (IL-4) and interleukin-10 (IL-10), and reduced ratios of p-JAK2/JAK2 and p-STAT3/STAT3 (P<0.05, P<0.01). ConclusionPaeoniflorin can alleviate cognitive impairment and neuroinflammation in the rat model of AD by inhibiting the JAK2/STAT3 signaling pathway.

Objective The aim of the study is to analyze the incidence patterns and epidemiological characteristics of parasitic and vector-borne diseases in the Minhang and Jinshan districts of Shanghai, and provide evidence-based information for optimizing prevention and control measures. Methods We collected information from epidemic reports and epidemiological investigation forms for cases of parasitic and vector-borne diseases from 2005 to 2024 in Shanghai's Minhang and Jinshan districts. Descriptive epidemiological method were adopted to conduct a comparative analysis of incidence trends, epidemic characteristics, and infection sources. Results A total of 229 cases in 7 categories were reported between 2005 and 2024, with an average annual incidence rate of 0.36/100 000. The average annual incidence rate in Minhang District was significantly higher than that in Jinshan District. The most prevalent diseases were malaria and dengue fever, followed by Japanese encephalitis. Monthly case reports were available, predominantly from June to October, with a peak in July-August. A statistically significant difference was observed between the two districts in case distribution during June-October (P<0.001), whereas no significant difference was found for July-August (P=0.331). The majority of cases were young men (111/229,48.47%), aged 20-39 years. Migrant workers/farmers constituted the largest occupational group (55/229, 24.02%). Registered residents of other provinces and cities (147/229,64.19%), and the main source of infection was overseas importation (112/229,48.91%). There were no statistically significant differences in gender and household-registration composition between the two districts (P>0.05). Significant differences existed in age, occupation, and source of infection (P<0.05). The imported diseases were malaria and dengue fever, with Africa and Southeast Asia being the primary source locations. Malaria was the predominant disease imported from other provinces and cities, with cases having been imported from abroad since 2012. Local infections were mainly Japanese encephalitis, followed by malaria (with the last local case reported in 2010). Cases between 2005 and 2009 were predominantly imported from other provinces and cities. The proportion of cases imported from abroad increased sharply after 2010, particularly in Minhang District. Local infections sometimes arise in Jinshan District, with Japanese encephalitis serving as the primary type. Conclusions Incidence rates of parasitic and vector-borne diseases in Minhang and Jinshan districts have generally remained low. To further reduce this disease burden, it will be necessary to strengthen joint measures for prevention and control, eliminate the environmental risk factors of vector organisms, enhance monitoring and precise control of the environment and inbound personnel to prevent the occurrence and transmission of parasitic and vector-borne diseases.

Objective:To analyze the risk factors for atrial high-rate episodes (AHRE) following cardiac resynchronization therapy (CRT) and construct a predictive model for the occurrence of AHRE.Methods:This was a case-control study. Patients who received CRT treatment for heart failure in the Second Affiliated Hospital of Second Affiliated Hospital of Army Military Medical University from January 2017 to December 2020 were selected and divided into AHRE group and non-AHRE group according to whether AHRE occurred during the follow-up period. Baseline clinical data were collected. Patients were followed up regularly after CRT or cardiac resynchronization therapy defibrillator (CRT-D) implantation until August 31, 2022. Logistic regression model was used to analyze the factors influencing the occurrence of AHRE in patients with heart failure treated with CRT, and a nomogram prediction model was established. The receiver operating characteristic (ROC) curve was used to evaluate the nomogram model, and the Hosmer-Lemeshow test was used to evaluate the consistency of the prediction model.Results:A total of 198 patients, aged (62±8) years, 138 (69.7%) males, were enrolled, of whom 52 (26.3%) patients developed AHRE (AHRE group) and 146 (73.7%) had no AHRE (non-AHRE group) during the follow-up period. Multivariate logistic regression analysis revealed that age, coronary heart disease, C-reactive protein, left atrial volume, and left ventricular ejection fraction (LVEF) were independent influencing factors of heart failure patients developing AHRE after CRT surgery (all P<0.05). A nomogram prediction model was constructed by combining 5 indicators: age, coronary heart disease, C-reactive protein, left atrial volume, and LVEF. In this model, a score of 4 was assigned for age ≥65 years, 4 for coronary heart disease, 4 for C-reactive protein ≥10 ng/ml, 20 for left atrial volume ≥35 ml, and 5 for LVEF ≤30%. The total score was obtained by accumulating the scores of each indicator, and the probability of heart failure patients developing AHRE after CRT surgery was predicted based on the total score. The area under the curve of the nomogram prediction model constructed in this study for predicting AHRE in heart failure patients after CRT surgery was 0.830 (95% CI: 0.795-0.866). The incidence of AHRE predicted by the model was basically consistent with the actual incidence of AHRE. The Hosmer-Lemeshow test indicated a good calibration of the model ( χ2=6.32, P=0.612). Conclusions:Age, coronary heart disease, C-reactive protein, left atrial volume, and LVEF are all independent risk factors for AHRE after CRT treatment. The nomogram prediction model based on the above factors can effectively predict the risk of AHRE in patients with heart failure after CRT, and the ROC curve and consistency test both show good prediction efficiency and consistency.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To summarize the clinical characteristics of elderly patients with stage Ⅰ diffuse large B-cell lymphoma (DLBCL) and analyze the factors associated with prognosis.Methods:A case series study was conducted by retrospectively collecting clinical data from patients aged over 60 years with newly diagnosed stage Ⅰ DLBCL across 20 medical centers in Jiangsu Province, China, between June 2010 and April 2023. The involved site, classification and treatment plan were summarized. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan-Meier method, and Cox regression model.Results:The study included 255 patients with a median age of 69 years, of whom 130 (51.0%) were male, 66 (25.9%) were aged ≥75 years and 26 (10.1%) had a high Charlson Comorbidity Index (CCI) score of ≥2. Extranodal involvement was observed in 163 (63.9%) patients, with the stomach (37.4%, 61/163), intestine (19.0%, 31/163), testes (11.0%, 18/163), and breast (7.4%, 12/163) being the most frequently affected sites. The non-germinal center B-cell (non-GCB) subtype was prevalent in 63.7% of patients (142/223), with no significant difference between the nodal and extranodal groups ( P=0.681). Furthermore, 73.9% (184/249) and 11.7% (29/249) of patients received the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) and R-miniCHOP regimen, respectively. The overall 3-year PFS rate was 81.5%, and the 3-year OS rate was 85.6%. Patients aged ≥75 years ( HR=2.910, 95% CI 1.565-5.408, P=0.001) and/or with a CCI score ≥2 ( HR=2.324, 95% CI 1.141-4.732, P=0.020) had a significantly poorer PFS. Incorporating age ≥75 years and CCI score ≥2 into the stage-modified international prognostic index (sm-IPI) can better stratify the prognosis of elderly patients with stage Ⅰ DLBCL. The 3-year PFS rate was 48.7% in the high-risk group versus 85.7% in the low-risk group ( P<0.001). Conclusions:Our findings show that the elderly patients with stage Ⅰ DLBCL were predominantly characterized by extranodal involvement (particularly in the stomach and intestinal tract) and non-GCB subtype. Age ≥75 years and CCI ≥2 were identified as independent prognostic factors. The newly established sm-IPI-75-CCI incorporating these factors demonstrated superior prognostic discrimination compared to conventional risk assessment systems.

Objective To analyze the association between lifestyle and the risk of type 2 diabetes(T2D)among adult residents.Methods The data was sourced from the Shanghai Suburban Adult Cohort and Biobank.A total of 42 096 adult residents who had not developed T2D were recruited from four districts of Shanghai(Songjiang,Jiading,Minhang,and Xuhui)between 2016 and 2019.The follow-up ended on Feb 28,2023.A structured questionnaire was used to collect information on six lifestyle-related items,including smoking,alcohol consumption,BMI,waist circumference(WC),physical activity,and diet.The unhealthy lifestyle scores(UHLS)were calculated by counting the number of all the unhealthy lifestyle items,with a range of 0-6.New-onset T2D events diagnosed by physicians were obtained through the medical information system.Cox proportional hazards regression model and restricted cubic spline model were utilized to evaluate the association between unhealthy lifestyles and the risk of T2D incidence.Results About 28.1%of the participants led 4-6 unhealthy lifestyles.A total of 1 752 new T2D cases were identified during 218 513.4 person-years of follow-up.Analysis of single unhealthy lifestyle showed that abnormal WC(HR=1.5,95%CI:1.4-1.7)and abnormal BMI(HR=1.3,95%CI:1.2-1.5)were associated with an increased risk of T2D.Compared with individuals with a UHLS of 0-1,those with a UHLS of 3 and 4-6 had 30%(95%CI:1.1-1.6)and 50%(95%CI:1.2-1.8)higher risks of T2D,respectively.Each additional unhealthy lifestyle was associated with a 10%increase in T2D incidence risk(HR=1.1,95%CI:1.1-1.2).Conclusion The risk of T2D in adult residents increases with the cumulative number of unhealthy lifestyles.Adult residents with abnormal WC or BMI,or have three or more unhealthy lifestyles accumulated,will increase the risk of new-onset T2D.
