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.

ObjectiveTo reveal the molecular mechanism by which the traditional Chinese medicine compound prescription Qiangjing tablets regulate the aging of the testicular tissue and Leydig cells in rats through the cyclin-dependent kinase 4 (CDK4)-early 2 factor (E2F) signaling pathway. MethodsFor the cell experiment, 2-month-old SPF-grade SD male rats were selected and randomly assigned into a blank control group (administrated with an equal volume of 0.9% sodium chloride injection) and a Qiangjing tablets group (20 rats in each group) according to body weight. The Leydig cell model of aging was established by treatment of TM3 cells with 100 μmol·L-1 H2O2, and the modeling performance was evaluated based on the levels of p16 and p21 determined by Western blot. The antioxidant NAC (1 mmol·L-1) was used as the positive control for eliminating reactive oxygen species (ROS). Cells were intervened with Qiangjing tablets-containing serum at low (2.5%), medium (5%), and high (10%) concentrations. The testosterone level in the cell supernatant was determined by enzyme-linked immunosorbent assay (ELISA), and the protein levels of CDK4, E2F1, and E2F2 were analyzed by Western blot. In the animal experiment, 19-month-old naturally aging rats were used as the model group, and 2-month-old rats as the young control group. The positive control group was subcutaneously injected with 5.21 mg·kg-1·d-1 testosterone propionate. Qiangjing tablets were administered by gavage at low, medium, and high doses of 0.72, 1.44, 2.88 g·kg-1·d-1, respectively. The general conditions of rats were observed, and the protein levels of CDK4, E2F1, and E2F2 in the testicular tissue were determined by Western blot. ResultsIn the cell experiment, compared with the blank control group, the model group showed upregulated expression of CDK4 and E2F1 (P<0.05) and slightly downregulated expression of E2F2. Compared with that in the model group, the expression of CDK4 was upregulated in the NAC group and the low-dose Qiangjing tablets group (P<0.05), slightly upregulated in the medium-dose Qiangjing tablets group, and downregulated in the high-dose Qiangjing tablets group (P<0.05). The NAC group showed downregulated expression of E2F1 (P<0.05) and E2F2, and the low-, medium-, and high-dose Qiangjing tablets groups showed downregulated expression of both E2F1 and E2F2 (P<0.05). Compared with that in the NAC group, the expression of CDK4 was upregulated in the low-dose Qiangjing tablets group and downregulated in the medium-dose and high dose (P<0.05) groups. The expression of E2F1 was down-regulated in all the three dose groups, with statistically significance in the high dose group (P<0.05), and that of E2F2 were downregulated in all the three dose groups (P<0.05). In the animal experiment, compared with the young control group, the model group exhibited downregulated expression of CDK4 (P<0.05) and slightly upregulated expression of E2F1 and E2F2. Compared with that in the model group, the expression of CDK4 decreased in the testosterone propionate group and the low-dose Qiangjing tablets group (P<0.05) but increased in the medium-dose (P<0.05) and high-dose groups. In addition, the expression of E2F1 decreased (P<0.05), and that of E2F2 was slightly elevated. Compared with that in the NAC group, CDK4 expression was elevated in the Qiangjing tablets groups, with statistical significance in the medium- and high-dose groups (P<0.05). Similarly, the E2F1 expression was also upregulated in the Qiangjing tablets groups, with statistical significance in the medium-dose group (P<0.05). The expression of E2F2 was downregulated in all the Qiangjing tablets groups. ConclusionQiangjing tablets delay the aging process of Leydig cells and testicular tissue by up-regulating the expression of CDK4 and lowering the levels of E2F1 and E2F2.

ObjectiveTo explore the mechanism by which Qiangjing tablets (QJT) alleviate the spermatogenic function damage caused by varicocele (VC) based on the Kelch-like ECH-associated protein 1 (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway-mediated oxidative stress. MethodsTen Sprague-Dawley (SD) rats were randomly assigned into a control group and a model group. Pathological examination confirmed the stability of the model. Thirty-six SD rats were randomized into control, model, low-dose (0.23 g·kg-1) QJT, medium-dose (0.46 g·kg-1) QJT, high-dose (0.92 g·kg-1) QJT, and mazhilin (61.7 mg·kg-1) groups, with 6 rats in each group. A rat model of experimental left varicocele (ELV) was established by partially ligating the left renal vein to simulate the human nutcracker syndrome. The rats were administrated with corresponding agents once a day for 28 consecutive days. The in vitro testicular culture model of rats was established through the Transwell chamber method and intervened with QJT-containing sera (2.3, 4.6, and 9.2 g·kg-1). Microscopic observation was carried out for the morphology of the left kidney. A micrometer was used to measure the diameter of the left spermatic vein (LSV). The body weights of rats were recorded weekly, and the epididymis and testis weights were measured. The pathological changes of the testicular tissue was observed via hematoxylin-eosin (HE) staining. The levels of testosterone (T) in the cell culture supernatant and reactive oxygen species (ROS) in the rat testicular tissue were measured by enzyme-linked immunosorbent assay (ELISA). Flow cytometry was employed to determine the ROS content. Immunohistochemical staining was conducted to analyze Keap1, Nrf2, 3β-hydroxysteroid dehydrogenase (3β-Hsd), GATA-binding protein-4 (Gata-4), and proto-oncogene receptor tyrosine kinase (C-kit). The ultrastructure of the tissue was observed by transmission electron microscopy (TEM). Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining. The expression of Keap1, Nrf2, glutathione S-transferase α2 (Gsta2), glutathione S-transferase μ1 (Gstm1), heme oxygenase-1 (HO-1), quinone oxidoreductase 1 (Nqo1), and thioredoxin reductase 1 (Txnrd1) was quantified by Real-time quantitative polymerase chain reaction(Real-time PCR) and Western blot. ResultsCompared with the control group, the ROS content and the percentage of apoptotic cells in the model group were significantly increased (P<0.01), the T concentration was significantly decreased (P<0.01), the mRNA and protein expressions of Keap1 were significantly increased (P<0.01), and the mRNA and protein expressions of Nrf2, Gsta2, Gstm1, HO-1, Nqo1 and Txnrd1 were significantly decreased (P<0.05). Compared with the model group, the ROS content and the percentage of apoptotic cells in each dose group of the Qiangjing Tablets were significantly reduced (P<0.05), and the mRNA and protein expressions of Keap1 were significantly decreased (P<0.05), while the mRNA and protein expressions of Nrf2, Gsta2, Gstm1, HO-1, Nqo1 and Txnrd1 were significantly increased (P<0.05). ConclusionQJT improves sperm motility in the rat model of VC by modulating the Keap1/Nrf2 signaling pathway and reducing oxidative stress injury.

ObjectiveBased on the multidimensional correlation analysis framework of "disease, syndrome, formula, and medicine", this study aims to systematically elucidate the regulatory effects of effective components in Qiangjing tablet on testosterone synthesis pathways in testicular Leydig cells under oxidative stress, providing a theoretical basis for the treatment of male infertility with traditional Chinese medicine and modern research on compounds. MethodsDisease targets for male infertility were obtained from The Human Gene Database (GeneCards, score ≥20), the Comparative Toxicogenomics Database (CTD, score ≥150), DrugBank (score ≥0.2), and DisGeNET (score ≥0.2). Targets related to the syndrome of kidney deficiency and blood stasis were acquired from the traditional Chinese medicine syndrome association database SymMap. Components of Qiangjing tablet were retrieved based on The Encyclopedia of Traditional Chinese Medicine (ETCM) database and the Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP), and they were screened according to a quantitative estimate of drug-likeness (QED ≥ 0.49) and a target confidence index>0.8. Intersecting targets were taken to construct a protein-protein interaction (PPI) network using the STRING database. The network was visualized with Cytoscape software and subjected to the functional annotation of gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis. Quality markers (Q-markers) were predicted via the ADMETlab 2.0 platform based on Lipinski's rule, Pfizer's rule, GSK's rule, and the Golden Triangle. For experimental validation, rats' testicular Leydig cells were used. Exosomes were extracted and loaded with active components via the ultrasonic method. Exosome concentration was determined using a BCA protein quantification kit. Morphology was observed using a transmission electron microscope. The particle size was analyzed with a particle size analyzer. The surface marker proteins such as cluster of differentiation 9 (CD9), cluster of differentiation 63 (CD63), and cluster of differentiation 81 (CD81) were identified by Western blot, and drug loading capacity was measured by high-performance liquid chromatography (HPLC). An oxidative stress model was induced by alpha, alpha'-azodiisobutyramidine dihydrochloride (AAPH), and Leydig cells were divided into the following groups: A control group, an AAPH group, a quercetin group (Que group), an exosome group (Exo group), and a QUE-loaded Exo group (Que-Exo group). The cell viability was detected using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) thiazolyl blue assay. The reactive oxygen species (ROS) levels and mitochondrial membrane potential were measured by flow cytometry. The levels of oxidative indicators, including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), and testosterone (T), were detected by enzyme-linked immunosorbent assay (ELISA). The expressions of steroidogenic enzymes such as cytochrome p450 family 11 subfamily a member 1 (CYP11A1), hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 1 (HSD3B1), and hydroxysteroid 17-beta dehydrogenase 3 (HSD17B3), regulatory factors such as steroidogenic factor 1 (SF-1) and steroidogenic acute regulatory protein (StAR), and miR-145-5p content, were detected by Western blot and real-time polymerse chain reaction (Real-time PCR). ResultsNetwork pharmacology analysis reveals that the main active components of Qiangjing tablet for intervening in male infertility with kidney deficiency and blood stasis syndrome were Que, luteolin, etc., with the core mechanism involving pathways such as steroid hormone biosynthesis. Experimental results show that compared with the control group, the AAPH group exhibits significantly reduced cell viability (P<0.01), decreased mitochondrial membrane potential (P<0.01), significantly elevated levels of ROS, MDA, and miR-145-5p (P<0.01), significantly reduced activities of SOD, GSH-Px, and CAT, as well as reduced testosterone content (P<0.01), and significantly downregulated protein and mRNA expressions of steroidogenic enzymes, SF-1, and StAR (P<0.01). The above indicators were reversed in the Que and Que-Exo groups (P<0.05). Compared with the Que group, the Que-Exo group showed more significant effects in enhancing cell viability, mitochondrial membrane potential, testosterone level, antioxidant enzyme activities, and expressions of key molecules in the steroidogenic pathway (P<0.05). ConclusionThis study demonstrates that Que, an active component of Qiangjing tablet, inhibits oxidative stress reaction, improves mitochondrial function in Leydig cells, upregulates steroidogenic enzyme expression, and restores testosterone production. As a carrier for Que, Exo enhance its stability, delivery efficiency, and biological effect. Additionally, miR-145-5p may be closely associated with testosterone synthesis, though its precise molecular mechanism requires further exploration. By integrating traditional Chinese medicine compounds with modern scientific technology, this research expands the paths for the modernized research of traditional Chinese medicine and opens a novel therapeutic direction with translational potential for clinical intervention of male infertility.

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.
