ObjectiveTo investigate the effects of Huangqi Jianzhongtang (HQJZ) on macrophage polarization and fat consumption in cancer cachexia (CC) mice. MethodsUltra-performance liquid chromatography-quadrupole/electrostatic field Orbitrap high-resolution mass spectrometry (UPLC-Q-Orbitrap HRMS) was used to control the quality of HQJZ. (1) In vitro experiment: HQJZ-containing serum was prepared, and the optimal concentration was determined by cytotoxicity assay. Mouse monocyte-derived macrophages (RAW264.7) were cultured and randomly divided into six groups, including a blank group, a classically activated macrophages (M1) group, an alternatively activated macrophages (M2) group, a HQJZ + blank group, a HQJZ+M1 group, and a HQJZ + M2 group. The relative expression of macrophage marker genes CD86, inducible nitric oxide synthase (iNOS), CD206, and arginase-1 (Arg1) was detected by real-time quantitative polymerase chain reaction (Real-time PCR ). (2) In vivo experiment: Thirty-two BALB/c mice were randomly divided into a control group, a model group, a medroxyprogesterone acetate (MPA) group, and a HQJZ group. Except for the control group, the other mice were injected with CT-26 colon cancer cells to establish a CC model. Mice in the MPA and HQJZ groups were given MPA (0.13 g·kg-1·d-1) or HQJZ (13.13 g·kg-1·d-1) by gavage, respectively, while mice in the control and model groups were given an equal volume of saline by gavage, with interventions continued for 10 d. Real-time PCR was used to detect the expression of macrophage markers (iNOS, Arg1, CD86, CD206) and fat browning-related genes uncoupling protein 1 (UCP1) and peroxisome proliferator-activated receptor γ (PPARγ) in epididymal adipose tissue. Western blot (WB) was used to detect protein expression levels of UCP1 and PPARγ. Micro-computed tomography (micro-CT) was used to measure residual fat volume, and hematoxylin-eosin (HE) staining was used to assess fat browning and calculate pathological scores. ResultsIn vitro, the dominant effective concentration of HQJZ-containing serum was 12.5%. Real-time PCR results showed that, compared with the blank group, Arg1 expression decreased in the HQJZ+blank group (P<0.05), CD206 showed a downward trend without statistical significance, while iNOS and CD86 expression were significantly increased (P<0.05). Compared with the M1 group, Arg1 and CD206 expression decreased in the HQJZ+M1 group (P<0.05). Compared with the M2 group, CD206 expression decreased in the HQJZ+M2 group (P<0.05), CD86 expression increased significantly (P<0.01). In vivo, Real-time PCR results showed that, compared with the control group, CD86 and CD206 expression levels were significantly increased in the model group (P<0.01). Compared with the model group, CD206 expression in the MPA group was significantly decreased (P<0.01). In the HQJZ group, CD206 was significantly decreased (P<0.01). WB results showed that, compared with the model group, protein expression of UCP1 and PPARγ was significantly reduced in the HQJZ group (P<0.05, P<0.01). micro-CT results showed that the total white fat volume in the HQJZ group was greater than that in the model group (P<0.05). HE staining results showed that pathological scores in the HQJZ group were lower than those in the model group (P<0.05). ConclusionHQJZ may inhibit white adipose tissue browning by promoting macrophage M1 polarization and suppressing M2 polarization, thereby delaying fat consumption in CC mice.

ObjectiveTo observe the clinical efficacy and safety of Yuyin Lidan granules (YYLD) in preventing the recurrence of common bile duct stones (CBDS) in patients with liver and gallbladder dampness-heat syndrome following endoscopic retrograde cholangiopancreatography (ERCP). MethodsThis randomized, parallel, controlled trial enrolled postoperative CBDS-ERCP patients who met the inclusion and exclusion criteria. Sixty-four patients were randomly assigned to an observation group or a control group, with 32 cases in each. Both groups received conventional Western medical treatment after ERCP, while the observation group additionally received YYLD for 8 weeks. The follow-up period lasted for 1 year. The efficacy indicators included bile bilirubin levels, traditional Chinese medicine (TCM) syndrome scores, clinical efficacy rate, pancreatitis and inflammation markers, postoperative liver function, and CBDS recurrence rate at 1-year follow-up, which were used to jointly evaluate the clinical efficacy and safety of both groups. ResultsA total of 56 patients completed the study and were included in the final analysis, i.e., 29 in the observation group and 27 in the control group. Baseline characteristics were comparable between the two groups. Compared with pre-treatment and with the control group after treatment, the bile bilirubin level in the observation group significantly decreased (P<0.05). After treatment, the clinical cure and marked improvement rates were higher in the observation group than in the control group, showing a statistically significant difference in overall clinical efficacy (P<0.05). Compared with pre-treatment, the primary and secondary symptoms in the observation group, as well as the primary symptom and the secondary symptom of nausea and vomiting in the control group (weeks 4 and 8), were significantly reduced (P<0.05). Compared with the control group after treatment, the observation group showed significant reductions in the primary symptom of loose stools/constipation (day 5 and week 4) and in three secondary symptoms, i.e., bitter taste and sticky dry mouth, abdominal distension and poor appetite (throughout the treatment period), and general heaviness and fatigue (day 5 and week 4), with statistical differences (P<0.05). Compared with pre-treatment, both groups showed decreased lipase and urinary amylase levels (P<0.05). However, no significant between-group differences were observed in pancreatitis or inflammation-related indices after treatment. Compared with pre-treatment, all liver function indicators in the observation group and alanine aminotransferase ( ALT ), γ-glutamyl transferase ( γ-GT ), alkaline phosphatase (ALP), and conjugated bilirubin in the control group significantly decreased at weeks 4 and 8 (P<0.05). Compared with the control group after treatment, only serum total bilirubin and unconjugated bilirubin were significantly reduced in the observation group during the treatment period (P<0.05). ConclusionYYLD combined with conventional Western medical treatment can effectively regulate bilirubin metabolism (in bile and serum), improve TCM clinical symptoms, and prevent CBDS recurrence after ERCP in patients with liver and gallbladder dampness-heat syndrome. This regimen is safe and effective and is worthy of further clinical research and promotion.

Objective To evaluate the short-term effects of comprehensive health management interventions for stroke high-risk population screening on the prevention and treatment of ischemic stroke, and to provide reference and basis for improving and exploring health management and prevention strategies for stroke high-risk population. Methods From 2018 to 2022, 13 community health service centers in Jiading District, Shanghai were selected in the present study. Based on information push platform, stroke risk assessment and health intervention follow-up were conducted for community residents through convenience sampling. The residents were divided into a full course intervention group (intervention group) and a routine intervention group (control group) according to different health intervention measures and forms. The incidence of ischemic stroke in the two groups of survey subjects was tracked within 36 months. Results A total of 52144 subjects were included in the study. The total number of patients in the full course intervention group was 14227, with an incidence density of 577.32/100 000 (556.49/100 000-598.12/100 000), which was lower than that of the conventional intervention group (37 917), with an incidence density of 1 485.47/100 000 (1 464.99/100 000-1 505.94/100 000) (χ2=2490.212, P<0.001). The relative risk of the full course intervention group was 0.39, and the relative risk of stroke risk factors in the full course intervention group from low to high was 0.33, 0.43, 0.45, and 0.49, respectively. The incidence density of males in the full course intervention group was 660.76 (627.46/100 000 - 694.05/100 000), with a relative risk of 0.43, and the incidence density of female patients was 509.71/100 000 (483.37/100 000 - 536.05/100 000), with a relative risk of 0.35. The overall incidence density of the population under 62 years old gourp, 62-75 years old group and over 75 years old group was 197.45/100 000 (173.09/100 000 -221.80/100 000), 608.36/100 000 (580.19/100 000-636.54/100 000), and 1 025.06/100 000 (958.51/100 000-1 091.61/100 000), with relative risks of 0.51, 0.44, and 0.38, respectively. Conclusion Comprehensive health management measures can effectively reduce the short-term risk of ischemic stroke, and should be further promoted and improved to enhance the effectiveness of stroke prevention and control.

BACKGROUND:Gradient artificial bone repair scaffolds can mimic unique anatomical features in musculoskeletal tissues,showing great potential for repairing injured musculoskeletal tissues. OBJECTIVE:To review the latest research advances in gradient artificial bone repair scaffolds for tissue engineering in the musculoskeletal system and describe their advantages and fabrication strategies. METHODS:The first author of the article searched the Web of Science and PubMed databases for articles published from 2000 to 2023 with search terms"gradient,bone regeneration,scaffold".Finally,76 papers were analyzed and summarized after the screening. RESULTS AND CONCLUSION:(1)As an important means of efficient and high-quality repair of skeletal system tissues,gradient artificial bone repair scaffolds are currently designed bionically for the natural gradient characteristics of bone tissue,bone-cartilage,and tendon-bone tissue.These scaffolds can mimic the extracellular matrix of native tissues to a certain extent in terms of structure and composition,thus promoting cell adhesion,migration,proliferation,differentiation,and regenerative recovery of damaged tissues to their native state.(2)Advanced manufacturing technology provides more possibilities for gradient artificial bone repair scaffold preparation:Gradient electrospun fiber scaffolds constructed by spatially differentiated fiber arrangement and loading of biologically active substances have been developed;gradient 3D printed scaffolds fabricated by layered stacking,graded porosity,and bio-3D printing technology;gradient hydrogel scaffolds fabricated by in-situ layered injections,simple layer-by-layer stacking,and freeze-drying method;and in addition,there are also scaffolds made by other modalities or multi-method coupling.These scaffolds have demonstrated good biocompatibility in vitro experiments,were able to accelerate tissue regeneration in small animal tests,and were observed to have significantly improved histological structure.(3)The currently developed gradient artificial bone repair scaffolds have problems such as mismatch of gradient scales,unclear material-tissue interactions,and side effects caused by degradation products,which need to be further optimized by combining the strengths of related disciplines and clinical needs in the future.

Aromatic inhalation therapy is a key traditional Chinese medicine (TCM) approach for preventing respiratory infectious diseases. Its foundational theory, "aromatics acting on the spleen", is deeply rooted in TCM principles and supported by modern medical research. The theory posits that the aromatic properties of medicinals primarily act on the spleen, and the aromatic inhalation therapy achieved its protective effects by modulation of the spleen and spleen channel to enhance the regulation of wei qi, striae and interstices. In TCM, the spleen is considered the mother of the lungs, with the function of nurturing lung; it is also seen as the source of wei qi, responsible for external defense; and the root of healthy qi, forming the foundation of acquired (postnatal) constitution. Thus, preventive strategies for respiratory infectious diseases focus on strengthening the spleen. From a modern medical perspective, the spleen's role in regulating lung immune responses, the shared immune functions of the respiratory and gastrointestinal mucosa, and the spleen's overall immune modulation provide scientific evidence for using aromatic inhalation therapy to prevent respiratory infections. Additionally, aromatic inhalation therapy offers several advantages, including direct action, rapid onset, minimal side effects, controllable risks, convenience, and ease of dissemination, making it a practical and effective preventive measure for respiratory infectious diseases.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

ObjectiveTo establish an educational intervention framework of electronic picture books for children with autism spectrum disorder (ASD) based on Creative Problem Solving (CPS) model, and observe the effect on social function. MethodsElectronic picture books were designed using CPS model, including the program of reading, interactive animation design and associated artistic activities. From March to June, 2023, 24 children with mild to moderate ASD were recruited from Maanshan Institute of Special Education, and randomly assigned into experimental group 1 (CPS-based cognitive picture book interventions, n = 8), experimental group 2 (CPS-based social picture book interventions, n = 8) and control group (Bloom's Taxonomy-based picture book interventions, n = 8), and received the interventions for four weeks, with a total of twelve times. They were assessed with speech, social, perceptual and health behavior using Autism Treatment Evaluation Checklist (ATEC) before and after treatment, and the differences were calculated. ResultsThere was a significant difference among the groups in the social and perceptual scores differences (F > 4.344, P < 0.05) and a near-significant difference in the health behaviour score difference (F = 2.921, P = 0.076). Post Hoc test showed that the differences in social scores were higher in both experimental groups than in the control group (P < 0.05); the difference in perceptual scores was significantly higher in experimental group 1 than in experimental group 2 (P < 0.01), but there was no significant difference with the control group (P > 0.05); the difference in health behavior scores was higher in experimental group 2 than in the control (P < 0.05), and the difference in experimental group 1 was slightly higher than in the control group (P = 0.072). ConclusionElectronic picture book interventions based on the CPS model may be more effective in enhancing social, perceptual and health behavior in children with ASD, but there may be differences among models.

Objective :
To investigate the protective effect of dimethyl fumarate(DMF) on maternal intrahepatic cholestasis(ICP) during pregnancy induced by di(2-ethylhexyl) phthalate(DEHP) exposure and its mechanism.
Methods :
Thirty-two 8-week-old female institute of cancer research(ICR) mice were randomly divided into 4 groups: Ctrl group, DEHP group, DMF group and DEHP+DMF group. DEHP and DEHP+DMF groups were treated with DEHP(200 mg/kg) by gavage every morning at 9:00 a.m. DMF and DEHP+DMF groups were treated with DMF(150 mg/kg) from day 13 to day 16 of gestation by gavage. After completion of gavage on day 16 of pregnancy, maternal blood, maternal liver, placenta, and amniotic fluid were collected from pregnant mice after a six-hour abrosia. The body weight of the mother rats and the body weight of the fetus rats were sorted and analyzed; the levels of total bile acid(TBA), alkaline phosphatase(ALP), aspartate aminotransferase/alanine aminotransferase(AST/ALT) in serum and TBA in liver, amniotic fluid and placenta were detected by biochemical analyzer; HE staining was used to observe the pathological changes of liver tissue; Quantitative reverse transcription PCR(RT-qPCR) was used to detect the expression levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-6, IL-1, IL-18 and NOD-like receptor thermal protein domain associated protein 3(NLRP3) in the liver; Western blot was used to detect the expression of the nuclear factor KappaB(NF-κB) and NLRP3.
Results :
Compared with the control group, the body weight of the DEHP-treated dams and pups decreased(P<0.05); the levels of TBA, ALP, AST/ALT in the serum of dams and the levels of TBA in the liver, amniotic fluid, and placenta of dams increased(P<0.05); the histopathological results showed that liver tissue was damaged, bile ducts were deformed, and there was inflammatory cell infiltration around them; the levels of inflammation-related factors TNF-α, IL-6, IL-1, IL-18 and NLRP3 transcription in maternal liver increased(P<0.05); the expression of NF-κB and NLRP3 protein in maternal liver significantly increased( P<0. 05). Compared with the DEHP group,the body weight of both dams and fetuses significantly increased in DEHP + DMF group( P<0. 05); the levels of TBA,ALP,AST/ALT in the serum of dams and amniotic fluid of fetuses decreased( P<0. 05); the degree of liver lesions was improved; the transcription levels of inflammation-related factors TNF-α,IL-6,IL-1,IL-18 and NLRP3 in maternal liver decreased( P<0. 05); the expression of NF-κB and NLRP3 protein in maternal liver significantly decreased( P<0. 05).
Conclusion
DMF can effectively protect the DEHP exposure to lead to female ICP,and its mechanism may be through inhibiting the NF-κB/NLRP3 pathway and reducing liver inflammation.

Based on commonly used acupoints in the clinical acupuncture treatment of functional dyspepsia (FD), this study systematically analyzes the therapeutic differences and synergistic effects between local and distal point selection. It also examines the suitability of primary acupoint selection for different FD subtypes, postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). The findings suggest that a combination of local and distal acupoints may be more appropriate as primary points for PDS, whereas local acupoints alone may be more suitable for EPS. Additionally, the study explores the impact of various factors, such as stimulation techniques, needling order, intensity or stimulation parameters, and depth, on the efficacy of acupuncture. It concludes that the intrinsic properties of acupoints are the primary determinants of therapeutic direction. Other factors mainly influence the magnitude rather than the direction of the effect. Future research may further investigate how different acupoint combinations, local versus distal, affect the treatment outcomes of FD subtypes, providing new insights for clinical acupuncture prescriptions.

Background The pathogenesis of silicosis has not been fully elucidated, and microRNAs (miRNA) may be involved in the occurrence and development of silicosis. Objective To investigate the effect of miR-204-3p inhibitor on the epithelial-mesenchymal transition (EMT) process and silicosis fibrosis in silicon dioxide dust-induced alveolar epithelial cells. Methods A co-culture model of macrophages and epithelial cells was established using a Transwell chamber. NR8383 macrophages were seeded into the upper chamber of the Transwell, and RLE-6TN cells were seeded into the lower chamber. After 24 h of culture, the medium in the lower chamber was discarded, washed three times with phosphate-buffered saline (PBS), and replaced with serum-free medium. The cells were divided into four groups: control group, silicosis group, miRNA NC group, and miR-204-3p inhibitor group. The lower chamber was transfected with miRNA NC for the miRNA NC group or the miR-204-3p inhibitor for the miR-204-3p inhibitor group. The lower chambers of the remaining two groups were added by equal amounts of serum-free medium. After 24 h, except for the control group that received an equal volume of serum-free medium, the upper chambers of the remaining three groups were treated with 800 μg·mL−1 silicon dioxide dust. Morphological changes in each group were observed under a microscope. The mRNA and protein expression levels of EMT-related factors, including α-smooth muscle actin (α-SMA), Vimentin, N-Cadherin, and E-Cadherin, were detected by reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) and Western blot. The mRNA and protein expression levels of fibrosis-related factors, including Collagen I, Collagen III, and Fibronectin, were also assessed by RT-qPCR and Western blot. The fluorescence expression intensities of α-SMA, N-Cadherin, and E-Cadherin were evaluated by immunofluorescence. Results The morphological observation revealed that RLE-6TN cells in the control group exhibited a regular oval shape. After treatment with silicon dioxide, the cells predominantly displayed a long spindle shape. Following the intervention with the miR-204-3p inhibitor, the number of long spindle-shaped cells increased, and the intercellular gaps widened. The RT-qPCR results showed that, compared with the control group, the silicosis group exhibited significantly higher relative mRNA expression levels of EMT-related markers (α-SMA, Vimentin, and N-Cadherin) (P<0.05), while the relative mRNA expression level of E-Cadherin was significantly reduced (P<0.05); the relative mRNA expression levels of fibrosis-related markers (Collagen I, Collagen III, and Fibronectin) were also significantly elevated (P<0.05). Compared with the miRNA NC group, the miR-204-3p inhibitor group showed significantly increased relative mRNA expression levels of α-SMA, Vimentin, and N-Cadherin (P<0.05), decreased E-Cadherin mPNA expression (P<0.05), and elevated mPNA expression of Collagen I, Collagen III, and Fibronectin (P<0.05). The Western blot analysis indicated that, compared with the control group, the silicosis group had significantly higher protein expression levels of α-SMA, Vimentin, and N-Cadherin (P<0.05), lower E-Cadherin protein expression (P<0.05), and increased protein expression of Collagen I, Collagen III, and Fibronectin (P<0.05). Compared with the miRNA NC group, the miR-204-3p inhibitor group exhibited significantly elevated protein expression levels of α-SMA, Vimentin, and N-Cadherin (P<0.05), reduced E-Cadherin expression (P<0.05), and increased protein expression of Collagen I, Collagen III, and Fibronectin (P<0.05). The immunofluorescence analysis demonstrated that, compared with the control group, the silicosis group showed enhanced fluorescence intensities of α-SMA and N-Cadherin and reduced fluorescence intensity of E-Cadherin. Compared with the miRNA NC group, the miR-204-3p inhibitor group exhibited increased fluorescence intensities of α-SMA and N-Cadherin and decreased fluorescence intensity of E-Cadherin. Conclusion The miR-204-3p inhibitor may exacerbate the EMT process and silicosis fibrosis in silicon dioxide-induced RLE-6TN cells. miR-204-3p plays a negative regulatory role in silicosis fibrosis.
