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 evaluate the effectiveness and safety of Sufei Pingchuan Formula (肃肺平喘方) in the treatment of bronchiectasis with airflow limitation, phlegm-heat obstructing the lung, and lung-spleen qi deficiency syndrome. MethodsA randomized, double-blind, placebo-controlled trial was conducted. A total of 72 patients with stable bronchiectasis with airflow limitation of phlegm-heat obstructing the lung and lung-spleen qi deficiency syndrome were randomly divided into treatment group and control group, with 36 cases in each group. On the basis of regular inhalation of tiotropium bromide inhalation spray, the treatment group was given Sufei Pingchuan Formula granules, and the control group was given Sufei Pingchuan Formula granule simulant. The course of treatment in both groups was 12 weeks. The pulmonary function of both groups before and after treatment was observed, specifically focusing on forced expiratory volume in one second (FEV1); the modified British Medical Research Council (mMRC) dyspnea scale, 24-hour sputum volume, COPD assessment test (CAT), and traditional Chinese medicine (TCM) syndrome scores were assessed before treatment and after 4, 8, and 12 weeks of treatment; acute exacerbations were recorded at weeks 4, 8, and 12; additionally, changes in routine blood tests, urinalysis, liver and kidney function, and adverse events were monitored before and after treatment. ResultsAfter treatment, 4 patients in the treatment group and 6 in the control group dropped out. After 12 weeks of treatment, FEV1 increased in both groups compared to pre-treatment levels (P<0.05), but the difference between groups was not statistically significant (P>0.05). Compared to before treatment, the treatment group showed a reduction in mMRC scores after 12 weeks (P<0.05) and a decrease in 24-hour sputum volume, CAT scores, and TCM syndrome scores at weeks 4, 8, and 12 (P<0.05). In the control group, 24-hour sputum volume decreased after 12 weeks (P<0.05), and TCM syndrome scores decreased at weeks 8 and 12 (P<0.05). Compared to the control group, the treatment group showed a greater reduction in mMRC scores at week 12 (P<0.05), a decrease in 24-hour sputum volume and TCM syndrome scores at weeks 4, 8, and 12 (P<0.05), and lower CAT scores at weeks 8 and 12 (P<0.05). The frequency and number of acute exacerbations in the treatment group were significantly lower than those in the control group at week 12 (P<0.05). No severe adverse events occurred in either group. ConclusionSufei Pingchuan Formula can improve the pulmonary function FEV1, the severity of dyspnea, reduce 24-hour sputum volume and frequent acute exacerbations, and improve the quality of life in patients with bronchiectasis and airflow limitation, with good safety.

ObjectiveTo evaluate the effects of Tongnaoyin on the blood-brain barrier status and neurological impairment in acute ischemic stroke (AIS) patients with the syndrome of phlegm-stasis blocking collaterals by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). MethodsA total of 63 patients diagnosed with AIS in the Jiangsu Province Hospital of Chinese Medicine from October 2022 to December 2023 were enrolled in this study. According to random number table method,the patients were assigned into a control group (32 cases) and an observation group (31 cases). The control group received conventional Western medical treatment,and the observation group took 200 mL Tongnaoyin after meals,twice a day from day 2 of admission on the basis of the treatment in the control group. After 7 days of treatment,the patients were examined by DCE-MRI. The baseline data for two groups of patients before treatment were compared. The National Institute of Health Stroke Scale (NIHSS) score and modified Rankin Scale (mRS) score were recorded before treatment and after 90 days of treatment for both groups. The rKtrans,rKep,and rVe values were obtained from the region of interest (ROI) of the infarct zone/mirror area and compared between the two groups. ResultsThere was no significant difference in the NIHSS or mRS score between the two groups before treatment. After 90 days of treatment,the NIHSS and mRS scores declined in both groups,and the observation group had lower scores than the control group (P<0.05). After treatment,the rKtrans and rVe in the observation group were lower than those in the control group (P<0.01). ConclusionCompared with conventional Western medical treatment alone,conventional Western medical treatment combined with Tongnaoyin accelerates the repair of the blood-brain barrier in AIS patients,thereby ameliorating neurological impairment after AIS to improve the prognosis.

Depression, a prevalent mental disorder with significant socioeconomic burdens, underscores the urgent need for safe and effective non-pharmacological interventions. Recent advances in microbiome research have revealed the pivotal role of gut microbiota dysbiosis in the pathogenesis of depression. Concurrently, exercise, as a cost-effective and accessible intervention, has demonstrated remarkable efficacy in alleviating depressive symptoms. This comprehensive review synthesizes current evidence on the interplay among exercise, gut microbiota modulation, and depression, elucidating the mechanistic pathways through which exercise ameliorates depressive symptoms via the microbiota-gut-brain (MGB) axis. Depression is characterized by gut microbiota alterations, including reduced alpha and beta diversity, depletion of beneficial taxa (e.g., Bifidobacterium, Lactobacillus, and Coprococcus), and overgrowth of pro-inflammatory and pathogenic bacteria (e.g., Morganella, Klebsiella, and Enterobacteriaceae). Metagenomic analyses reveal disrupted metabolic functions in depressive patients, such as diminished synthesis of short-chain fatty acids (SCFAs), impaired tryptophan metabolism, and dysregulated bile acid conversion. For instance, Bifidobacterium longum deficiency correlates with reduced synthesis of neuroactive metabolites like homovanillic acid, while decreased Coprococcus abundance limits butyrate production, exacerbating neuroinflammation. Furthermore, elevated levels of indole derivatives from Clostridium species inhibit serotonin (5-HT) synthesis, contributing to depressive phenotypes. These dysbiotic profiles disrupt the MGB axis, triggering systemic inflammation, neurotransmitter imbalances, and hypothalamic-pituitary-adrenal (HPA) axis hyperactivity. Exercise exerts profound effects on gut microbiota composition, diversity, and metabolic activity. Longitudinal studies demonstrate that sustained aerobic exercise increases alpha diversity, enriches SCFA-producing genera (e.g., Faecalibacterium prausnitzii, Roseburia, and Akkermansia), and suppresses pathobionts (e.g., Desulfovibrio and Streptococcus). For example, a meta-analysis of 25 trials involving 1 044 participants confirmed that exercise enhances microbial richness and restores the Firmicutes/Bacteroidetes ratio, a biomarker of metabolic health. Notably, endurance training promotes Veillonella proliferation, which converts lactate into propionate, enhancing energy metabolism and delaying fatigue. Exercise also strengthens intestinal barrier integrity by upregulating tight junction proteins (e.g., ZO-1, occludin), thereby reducing lipopolysaccharide (LPS) translocation and systemic inflammation. However, excessive exercise may paradoxically diminish microbial diversity and exacerbate intestinal permeability, highlighting the importance of moderate intensity and duration. Exercise ameliorates depressive symptoms through multifaceted interactions with the gut microbiota, primarily via 4 interconnected pathways. First, exercise mitigates neuroinflammation by elevating anti-inflammatory SCFAs such as butyrate, which suppresses NF-κB signaling to attenuate microglial activation and oxidative stress in the hippocampus. Animal studies demonstrate that voluntary wheel running reduces hippocampal TNF‑α and IL-17 levels in stress-induced depression models, while fecal microbiota transplantation (FMT) from exercised mice reverses depressive behaviors by modulating the TLR4/NF‑κB pathway. Second, exercise regulates neurotransmitter dynamics by enriching GABA-producing Lactobacillus and Bifidobacterium, thereby counteracting neuronal hyperexcitability. Aerobic exercise also enhances the abundance of Lactobacillus plantarum and Streptococcus thermophilus, which facilitate 5-HT and dopamine synthesis. Clinical trials reveal that 12 weeks of moderate exercise increases fecal Coprococcus and Blautia abundance, correlating with improved 5-HT bioavailability and reduced depression scores. Third, exercise normalizes HPA axis hyperactivity by reducing cortisol levels and restoring glucocorticoid receptor sensitivity. In rodent models, chronic stress-induced corticosterone elevation is reversed by probiotic supplementation (e.g., Lactobacillus), which enhances endocannabinoid signaling and hippocampal neurogenesis. Furthermore, exercise upregulates brain-derived neurotrophic factor (BDNF) via microbial metabolites like butyrate, promoting histone acetylation and synaptic plasticity. FMT experiments confirm that exercise-induced microbiota elevates prefrontal BDNF expression, reversing stress-induced neuronal atrophy. Fourth, exercise reshapes microbial metabolic crosstalk, diverting tryptophan metabolism toward 5-HT synthesis instead of neurotoxic kynurenine derivatives. Butyrate inhibits indoleamine 2,3-dioxygenase (IDO), a key enzyme in the kynurenine pathway linked to depression. Concurrently, exercise-induced Akkermansia enrichment enhances mucin production, fortifies the gut barrier, and reduces LPS-driven neuroinflammation. Collectively, these mechanisms underscore exercise as a potent modulator of the microbiota-gut-brain axis, offering a holistic approach to alleviating depression through microbial and neurophysiological synergy. Current evidence supports exercise as a potent adjunct therapy for depression, with personalized regimens (e.g., aerobic, resistance, or yoga) tailored to individual microbiota profiles. However, challenges remain in optimizing exercise prescriptions (intensity, duration, and type) and integrating them with probiotics, prebiotics, or FMT for synergistic effects. Future research should prioritize large-scale randomized controlled trials to validate causality, multi-omics approaches to decipher MGB axis dynamics, and mechanistic studies exploring microbial metabolites as therapeutic targets. The authors advocate for a paradigm shift toward microbiota-centric interventions, emphasizing the bidirectional relationship between physical activity and gut ecosystem resilience in mental health management. In conclusion, this review underscores exercise as a multifaceted modulator of the gut-brain axis, offering novel insights into non-pharmacological strategies for depression. By bridging microbial ecology, neuroimmunology, and exercise physiology, this work lays a foundation for precision medicine approaches targeting the gut microbiota to alleviate depressive disorders.

Pulmonary endometriosis (PEM) is a rare disease with diverse clinical manifestations, most commonly presenting as hemoptysis, while patients presenting solely with pulmonary nodules are less common. Here, we report three female patients (aged 32, 19, and 46 years, respectively). One patient sought medical attention due to hemoptysis during menstruation, while the other two had no obvious symptoms and were found to have pulmonary nodules during routine physical examinations. Two patients had a history of cesarean section, and one had a history of miscarriage. Pathologically, one patient of PEM showed extensive hemorrhage in the alveolar spaces, with fragmented endometrial glandular epithelium observed within the hemorrhagic foci. The other two patients exhibited proliferative endometrial glands and stroma, surrounded by old hemorrhage. Immunohistochemistry revealed that the endometrial glands and stroma in all three patients were positive for estrogen receptor, progesterone receptor, and vimentin, with CD10 positivity in the endometrial stroma. All three patients were definitively diagnosed as PEM by pathology and underwent thoracoscopic pulmonary wedge resection. Follow-up periods were 18, 31, and 49 months, respectively, with no recurrence observed in any of the patients.

Objective:To investigate the degree of satisfaction with education of undergraduates majoring in medical technology in medical universities in China and associated problems, and to put forward countermeasures and suggestions for student training.Methods:A questionnaire was distributed to undergraduates majoring in medical technology selected by stratified sampling from Shanghai Jiao Tong University, Tianjin Medical University, and Shanghai University of Medicine & Health Sciences. The questionnaire covered demographic characteristics, major choice motivation, education satisfaction, and various aspects, including a total of 54 variables (21 nominal variables and 33 continuous variables). Statistical analysis was performed by using SPSS 27.0 One-way analysis of variance was used for group comparison.Results:The mean degree of satisfaction with education of the students of medical technology was 4.02 points, with the highest score for curricula and teaching and the lowest score for academic atmosphere. Cultivation and management showed the strongest correlation with the degree of satisfaction with education. The degree of satisfaction with education differed significantly for different institutions and different major choice motivations ( P<0.05). Conclusions:Undergraduates of medical technology are generally satisfied with their education, and the degree of satisfaction is lower in double first-class universities than in application-oriented ordinary universities. Attention should be paid to student training and management, creating a positive academic atmosphere, and enhancing the attractiveness of colleges/universities and majors. Compared with application-oriented undergraduate colleges/universities, double first-class universities should well coordinate training goals with students' expectations, industry needs, and even national strategic needs. Colleges and universities can make appropriate adjustments in terms of curricula, teaching, and teaching resources, to promote the diverse and orderly development of medical technology talents based on their personal strengths.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.
