Objective: To enhance the ability of nanoparticles to target and bind tumor cells by constructing a neutrophil hitchhiking system based on hyaluronic acid (HA)-modified dual-drug loaded lipid nanoparticles. Methods: Lipid nanoparticles (LNPs) were prepared using microfluidic technology, and the nitrogen/phosphate (N/P) ratio, flow rate ratio, and drug-to-lipid ratio were optimized. HA-modified LNPs (HA-LNPs) were prepared and characterized. The interaction between the nanoparticles and tumor cells was evaluated through in vitro cell experiments. Results: The optimal preparation conditions for LNPs are N/P=8, flow rate ratio=5, and drug-to-lipid ratio=1∶30 (w∶w). HA-LNPs has a particle size of (177.28±2.41) nm, a polydispersity index (PDI) of 0.198±0.10, and an siRNA encapsulation efficiency of (91.37±0.47)%. The optimal binding rate with neutrophils was (98.64±2.34)%. Conclusion: An HA-modified dual-drug loaded lipid nanoparticle-neutrophil hitchhiking system was successfully constructed, enhancing the synergistic anti-tumor activity of the nanomedicine and the uptake of nanoparticles by tumor cells, providing a novel delivery strategy for targeted therapy of bone marrow tumors.

Objective:To investigate the clinicopathological and molecular genetic features of high-grade astrocytomas with piloid features (HGAP).Methods:Clinical, histopathological and imaging data of 7 cases of HGAP diagnosed at the Neuropathology Center of Beijing Tiantan Hospital, Beijing, China from August 2023 to October 2024 were collected. The histopathological and molecular features for each case were analyzed.Results:Among the seven patients there were 4 males and 3 females, with the median age of 37 (34, 51) years. Patients exhibited various clinical symptoms and signs depending on the tumor′s location. Four tumors were located in the cerebellum, 2 in the supratentorial region, and 1 in the spinal cord. Magnetic resonance imaging showed that 6 of the 7 patients had cystic and solid lesions, with focal or nodular enhancement and relatively unclear boundaries. Histopathological features had a diverse morphological spectrum and extensive grading. Five cases displayed a pilocytic astrocytoma-like appearance with infiltrative growth patterns, while two cases presented glioblastoma-like morphology, containing locally anaplastic pleomorphic xanthoastrocytoma with minor pilocytic components. All tumors were diffusely positive for GFAP and Olig2, while 4 tumors exhibited partial or complete loss of ATRX. The Ki-67 proliferation index ranged from 2% to 40%. Next-generation sequencing showed that tumor cells most commonly harbored MAPK pathway gene mutations, and/or homozygous deletions of CDKN2A/B, and/or ATRX mutations. Among the 7 HGAP models, 3 cases showed the three types of molecular genetic variations, 1 case showed MAPK mutations and homozygous deletions of CDKN2A/B, 1 case had MAPK mutations and ATRX mutations, 1 case had only MAPK mutations, and 1 case showed no detectable molecular changes. DNA methylation clustering analyses showed that the median model prediction score was 0.94 (range, 0.85-0.99) for the 7 HGAP models. Five cases showed the MGMT promoter hypermethylation. Four patients received radiotherapy and concomitant temozolomide treatment after surgery, while three patients received no known treatments. At the last follow-up, seven patients were alive without any tumor, two patients had recurrence, and one patient was alive with the tumor.Conclusions:HGAP is relatively rare and predominantly occurs in adults. It has a wide histopathological spectrum and various histological grades, characterized by piloid astrocytoma-like and glioblastoma-like histological features. Its diagnosis relies on methylation clustering analysis. Most tumors harbor gene alterations in the MAPK signaling pathway, along with homozygous deletions of CDKN2A/B or ATRX mutations. The biological behavior is typically aggressive, while imaging and histological findings can be misleading. Therefore, clinicians need to increase their diagnostic awareness of this tumor and prevent missed diagnoses.

Objective To investigate the multi-target mechanisms of quercetin in treating endometriosis(EMT)through integrative network pharmacology analysis.Methods Active targets of quercetin were collected from the TCMSP database,while EMT-related differentially expressed genes(DEGs)were identified through the Gene Expression Omnibus(GEO)dataset.A comparative analysis was conducted to pinpoint potential therapeutic targets of quercetin for EMT treatment.Functional enrichment analyses were employed to investigate the biological functions associated with these targets,and a protein-protein interaction(PPI)network was conducted to identify core targets.Molecular docking and dynamics simulations were performed to validate the binding characteristics between quercetin and the core targets.The top 2 target protein pairs,HSP90AB1 and AR,exhibiting the lowest binding energy,were selected for subsequent cellular experimental validation.Human EMT-immortalized ectopic endometrial epithelial cell line 12Z(n=6,independent replicates)was subjected,and CCK-8 assay was used to determine ehe effects of quercetin on cell viability and proliferation,and the half-maximal inhibitory concentration(IC50)was calculated at 48 h after treatment.Then the 12Z cells were treated with quercetin at a concentration gradient of 0,30,60 and 90 μmol/L,the migration and invasion abilities were assessed with cell scratch and cell invasion assays.Western blotting was conducted to detect the changes in the expression of HSP90AB1 and AR proteins after different doses of treatment.Results There were 49 potential EMT-related therapeutic targets and 10 core targets identified.Functional enrichment analyses revealed that these targets were significant enriched in inflammation-related signaling pathways,including AGE-RAGE,ErbB and TNF;immune-related pathways,such as Th17 cell differentiation,T/B cell receptor signaling;angiogenesis-related pathways like VEGF;and hormonal regulatory pathways involving estrogen and GnRH.Molecular docking demonstrated that quercetin exhibited favorable binding activity(binding energy<-5 kcal/mol)with all core target proteins,with particularly strong binding energies(<-7 kcal/mol)observed for AR,EGFR,FOS,ERBB2,and HSP90AB1.Molecular dynamics simulations revealed that quercetin forms sustained hydrogen bond interactions with AR and HSP90AB1,facilitating the formation of stable complexes.CCK-8 assay,cell scratch assay,and transwell invasion assay indicated that quercetin inhibited the proliferative activity,and migrative and invasive abilities of 12Z cells in a concentration-dependent manner,with more pronounced inhibitory effects observed at 60 and 90 μmol/L quercetin(P<0.001);Western blotting revealed that treatment of 12Z cells with varying quercetin concentrations for 48 h up-regulated the expression of HSP90AB1 and AR,with the most significant increase observed at 90 μmol/L quercetin(HSP90AB1,P<0.05;AR,P<0.001).The restored expression levels of HSP90AB1 and AR showed positive correlations with the proliferative activity,migrative and invasive abilities of ectopic endometrial cells.Conclusion Quercetin effectively addresses endometriosis through multiple molecular targets and signaling pathways,and stabilization of the HSP90AB1/AR complex and subsequent protein upregulation represents a key therapeutic mechanism.

[Objective] To investigate the effect of Shenmai injection on the preservation quality of suspended red blood cells of high hemoglobin population in Xizang plateau. [Methods] Whole blood (400 mL, n=8) collected by the Xizang Autonomous Region Blood Center was centrifuged at 3 000 g for 10 minutes to remove most of the plasma, followed by the addition of 100 mL of MAP preservation solution to obtain plateau suspended red blood cells, which were then divided into three equal portions. One portion was the control group, and another part had 15 mL of MAP preservation solution added, which was the dosage group. The third portion involved diluting Shenmai injection with MAP, followed by addition of 15 mL of MAP preservation solution containing Shenmai to the red blood cells, resulting in a final concentration of Shenmai injection of 1%, which was the Shenmai group. Blood routine, pH value, electrolytes, glucose, lactate, free Hb, adenosine triphosphate (ATP), P50, phosphatidylserine (PS) and other indicators were detected at day 1, 21 and 35, respectively. [Results] The Hb concentration and Hct of the dosage group and the Shenmai group were significantly lower than those of the control group, with values of (179.3±17.8) vs (181.0±17.1) vs (199.1±19.5) g/L for Hb concentration and (53.2±2.6)% vs (53.3±2.5)% vs (58.4±3.1)% for Hct. The three groups maintained this pattern until the end of storage. In the middle and late stages of preservation, the glucose and Na⁺ contents in the dosage group and the Shenmai group were higher than those in the control group, while the lactate and K⁺ contents were lower than those in the control group. At the end of storage, the glucose and Na⁺ content of the Shenmai group was higher than that of the dosage group, while the lactate and K⁺ content were lower than that of the dosage group. From day 1 to day 35 of storage, the hemolysis rate of the Shenmai group was significantly lower than that of the control group and the dosage group. On day 21 and 35 of storage, the PS expression rate in the Shenmai group was significantly lower than that in the control group and the dosage group, which were (6.52±0.40)% vs (7.24±0.91)% vs (8.27±0.93)% and (7.29±0.53)% vs (9.37±0.82)% vs (8.39±0.76)%, respectively. [Conclusion] The hemolysis rate and PS of suspended red blood cells of Xizang high altitude prepared by adding Shenmai injection were significantly lower than those in the control group and the dosage group, which was conducive to reducing hemolysis and slowing down the aging of red blood cells, and had a certain improvement on the preservation quality of suspended red blood cells in Xizang plateau people.

[Objective] To use Chitosan Methacryloyl (CSMA) loaded with artificial platelet-derived exosomes (aPexos) as the needle body material, and gelatin and carboxymethyl chitosan (CMCS) loaded with Epigallocatechin gallate(EGCG) as the backing material to prepare microneedles, aims to investigate the therapeutic effect and mechanism of aPexos-EGCG microneedles in the treatment of burn wound healing. [Methods] First, aPexos were extracted using ultrasound and gradient ultracentrifugation. The concentration, morphology, and growth factor content (TGF-β1, PDGF-BB, VEGF) of the exosomes were assessed using NTA, transmission electron microscopy, and ELISA kits. The aPexos and EGCG were then dissolved in the needle body and backing materials, respectively. The aPexos and EGCG were loaded into the needle body and backing layer, respectively. The morphology, mechanical properties, and puncture performance of the microneedles were examined, and the preparation conditions for the microneedles loaded with aPexos-EGCG were optimized. Finally, animal experiments and tissue staining were conducted to assess the efficacy of the aPexos-EGCG microneedles in promoting burn wound healing in rats. [Results] The size distribution of aPexos was mainly in the range of 50-150 nm, with an average diameter of 132.7±3.8 nm and an average concentration of approximately 2.88×10¹³±3.62×10¹² particles/mL. The concentrations of TGF-β1, PDGF-BB, and VEGF were approximately 1 363±135.9 ng/mL, 63.5±14.8 ng/mL, and 1 606.0±77.5 pg/mL, respectively. Mechanical property testing of the microneedles indicated that, compared with the blank microneedles, the drug-loaded microneedles had sufficient piercing ability to penetrate the stratum corneum of the skin. The results of the rat burn wound healing experiment showed that the wound healing rates of the d 3, d 7, aPexos-EGCG microneedle group compared to the control group showed significant differences, with respective values of (47.64±12.5)% vs (18.11±6.40)%, (87.45±5.57)% vs (79.85±5.03)%(P<0.05). Hematoxylin-eosin (HE) staining revealed more intact epidermal layers in the aPexos-EGCG microneedle group. Masson staining showed that the collagen deposition percentage in the aPexos-EGCG microneedle group was higher than in the control group. Immunofluorescence staining results indicated that the aPexos-EGCG microneedle group had a reduced content of M1-type macrophages and an increased content of M2-type macrophages. Additionally, the vascular markers CD31 and α-SMA showed elevated expression in this group, with significant differences compared to the other groups (P<0.05). [Conclusion] The aPexos-EGCG microneedle developed in this study exhibits good mechanical properties, capable of successfully penetrating the skin's stratum corneum and delivering aPexos and EGCG. aPexos promotes wound repair, while EGCG regulates the ratio of M1 and M2 macrophages at the wound site and suppresses the inflammatory response. This microneedle can effectively promote wound healing in rats with burn injuries, offering a novel approach for tissue repair.

Objective:To explore the risk assessment and intervention effect of WeChat platform-based health management in high-risk populations for cardiovascular diseases (CVD).Methods:It was a randomized controlled trial. A total of 480 individuals at high risk of CVD who underwent physical examinations at the Health Management Center of Sichuan Provincial People′s Hospital from February to April in 2023 were selected using a simple random sampling method. The participants were randomly assigned to either the intervention group or the control group (240 cases each) using a random number table. The control group received routine follow-up and health assessments, while the intervention group received an additional 12-month WeChat-based health management intervention. During the study, 28 participants were lost to follow-up, resulting in 227 participants in the intervention group and 225 in the control group being included in the final analysis. The 10-year CVD risk was assessed using the prediction for atherosclerotic cardiovascular disease risk in China (China-PAR) model, and psychological status was evaluated using the self-rating anxiety Scale (SAS) and the self-rating depression scale (SDS). Changes in health behaviors, adherence, life style, blood pressure, metabolic indicators, psychological status, and CVD risk were compared before and after the intervention in both groups to evaluate the intervention′s effectiveness.Results:Among the 452 high-risk participants analyzed, the intervention group included 227 individuals [mean age: (53.16±10.81) years; 117 males and 110 females], and the control group included 225 individuals [mean age: (52.60±10.25) years; 118 males and 107 females]. There was no significant differences in baseline characteristics between the two groups (all P>0.05). After 12 months of intervention, the intervention group showed significant improvements in medication adherence, intake of vegetables and fruits, exercise duration, sleep time, proportion of regular lifestyle, and high density lipoprotein cholesterol (HDL-C) levels, all of which were all higher than both the baseline values and those in the control group (all P<0.05). Conversely, the intervention group showed reductions in medical visit rate, smoking and drinking rates, high-salt diet, meat intake, body mass index (BMI), fasting blood glucose, systolic and diastolic blood pressure, low density lipoprotein cholesterol (LDL-C), total cholesterol, triglycerides, SAS and SDS scores when compared to the baseline values and those in the control group (all P<0.05). The proportions of participants with 10-year CVD risk levels of 10%-<20%, 20%-<30%, 30%-<40%, and ≥40% significantly decreased in the intervention group after intervention (18.94% vs 36.12%, 12.78% vs 26.43%, 7.93% vs 19.82%, 3.96% vs 17.63%), and were also significantly lower than those in the control group (18.94% vs 40.45%, 12.78% vs 30.67%, 7.93% vs 22.67%, 3.96% vs 16.89%) (all P<0.001). After 12 months, the intervention group showed significantly higher improvement rates in both medication adherence and non-medication-related compliance behaviors, including smoking, alcohol consumption, meat and salt intake, fruit and vegetable intake, exercise duration, sleep duration, and lifestyle regularity, when compared to those in the control group (16.74% vs -3.11%, 14.54% vs -0.89%, 16.74% vs -0.44%, 57.71% vs 8.44%, 21.15% vs -0.44%, 56.83% vs -6.67%, 51.54% vs -3.56%, 60.79% vs -7.11%, 26.87% vs -13.78%, 22.91% vs -1.78%) (all P<0.001). Conclusion:The WeChat platform-based health management intervention can effectively improve the behavioral patterns, compliance, control of CVD risk factors and psychological status of high-risk populations for CVD, and help reduce their 10-year risk of CVD.

Objective:To analyze the advantages of the impact of physical activity management under medical supervision on body components and healthy physical fitness.Methods:A total of 106 healthy adults who participated in physical activity management activities in the Health Management Center of Sichuan Academy of Medical Sciences & Sichuan Provincial People′s Hospital from April 1 st 2020 to May 31 th 2021 were enrolled. The subjects were equally divided into a medical supervision group and a self-supervision group with random number table. Both groups performed a 8-week physical activity intervention, followed by the model of “a combination of online home physical activity with offline team exercise, and team exercise interaction with individual physical activity guidance”, while health education was provided and wearable devices were worn to collect exercise data. The medical supervision group completed the set number of exercises under the supervision of the team, with on-site exercise guidance. They were required to participate in weekly one-to-one on-site instruction. The self-management group carried out exercises and participated in weekly one-to-one instruction in accordance according to their own will with online feedback. During the study, 6 cases withdrew, and 52 cases in the supervision group and 48 in the self-management group were obtained. The t and Wilcoxon tests were used to compare the body components and physical fitness of the two groups before and after intervention. Results:The amount of exercise in the supervision group was significantly higher than that in self-management group (1 359 vs 615), and there was no significant differences in exercise intensity (mean heart rate, maximum heart rate and exercise duration) between the two groups (all P>0.05). After the intervention, the body weight, body mass index (BMI), percent body fat, subcutaneous fat area and strength fitness of the supervision group were significantly lower than those before the intervention [(55.36±6.37) vs (56.11±6.33) kg, (21.48±2.85) vs (21.73±2.47) kg/m 2, (27.38±5.34) % vs (28.53±4.99) %, (119.56±48.45) vs (128.70±50.10) cm 2, (24.48±6.37) vs (26.07±5.29) kg], while the cardiorespiratory endurance, flexibility fitness and agility fitness were significantly higher [(33.57±5.06) vs (30.32±4.59) ml·kg -1·min -1, (14.71±7.51) vs (10.54±7.54) cm, (0.44±0.08) vs (0.48±0.05) s] (all P<0.05). After the intervention, the body weight, muscle mass and lean body mass in self-management group were all significantly higher than those before the intervention [(56.83±8.09) vs (56.45±8.22) kg, (38.28±3.19) vs (38.24±5.17) kg; (40.80±4.16) vs (40.32±4.95) kg], and agility fitness was significantly lower [(0.64±0.39) vs (0.49±0.05) s] (all P<0.05). It was also found that improvements regarding the following three indicators were more significant in the supervision group: visceral fat, balance and agility fitness (all P<0.05). Conclusions:Physical activity intervention under medical supervision can significantly improve the body components and physical fitness in healthy adults, as well as exercise compliance and validity.
