ObjectiveTo explore the mechanism by which Banxia Xiexin Tang (BXT) regulates the advanced glycation end products (AGE)/receptor for advanced glycation end products (RAGE) signaling pathway to reduce neuroinflammatory responses and ameliorate cognitive dysfunction in the rat model of vascular dementia (VD). MethodsThe components of BXT were detected by ultra performance liquid chromatography-quadrupole -orbitrap-tandem mass spectrometry(UPLC-Q-Orbitrap-MS/MS), and the core components and key action pathways were screened out by network pharmacology and molecular docking. Sixty SPF-grade male SD rats were randomly allocated into the sham and modeling groups by the random number table method. The VD model was replicated by the modified bilateral occlusion of the common carotid arteries (2-VO) method. The successfully modeled rats were randomly allocated into the model, low-, medium-, and high-dose (3.748 5, 7.497, 14.994 g·kg-1) BXT (BXT-L, BXT-M, and BXT-H), and nimodipine (NMP, 0.002 7 g·kg-1) groups according to the random number table method. The rats in the drug intervention groups were administrated with corresponding drugs by gavage, and the sham and model groups received the same amount of normal saline for 14 consecutive days. The Morris water maze, Y-maze, and new object recognition experiments were conducted to evaluate the cognitive dysfunction of rats. Hematoxylin-eosin (HE) staining was used to evaluate the histopathological changes of the hippocampal tissue in rats. The mRNA levels of AGE, RAGE, and phosphorylated nuclear factor-kappa B p65 (p-NF-κB p65) in the hippocampal tissue of rats were determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The expression of related proteins in the AGE/RAGE pathway in the hippocampal tissue of rats was determined by Western blot and immunohistochemistry (IHC). The levels of neurotransmitters and inflammatory mediators in the rat serum were measured by enzyme-linked immunosorbent assay (ELISA). ResultsThe chemical components of BXT were detected by UPLC-Q-Orbitrap-MS/MS. Network pharmacology and molecular docking identified the AGE/RAGE pathway as the key pathway. The results of the water maze, Y maze, and novel object recognition tests showed that compared with the sham group, the model group demonstrated prolonged successful latency and decreases in number of platform crossings, alternation rate, number of entries into the new arm, preference index, and discrimination index (P0.01). Compared with the model group, the BXT-H and BXT-M groups showed shortened successful latency (P0.01) and increases in number of platform crossings (P0.05), alternation rate (P0.01), number of entries into the new arm (P0.05), preference index (P0.01), and discrimination index (P0.01). HE results showed that compared with the sham group, the cells of model rats were loosely and disorderly arranged, and the nuclei were condensed. Compared with the model group, the pathological changes of the hippocampus in the BXT group were mitigated. Real-time PCR results showed that compared with the sham group, the model group presented up-regulated mRNA levels of AGE, RAGE, and p-NF-κB p65 in the hippocampus (P0.01), and compared with the model group, the BXT-H and BXT-M groups showcased down-regulated mRNA levels of AGE, RAGE, and p-NF-κB p65 (P0.01). Western blot results showed that compared with the sham group, the model group presented up-regulated expression of AGE, RAGE, p-NF-κB p65, and tumor necrosis factor-α (TNF-α) (P0.05), and compared with the model group, the BXT-H group presented down-regulated expression of AGE, RAGE, p-NF-κB p65, and TNF-α (P0.05). IHC results showed that compared with the sham group, the model group had increased expression of RAGE (P0.01), and compared with the model group, the BXT-H and BXT-M groups had reduced expression of RAGE (P0.01). ELISA results showed that compared with the sham group, the model group exhibited elevated levels of TNF-α and Interleukin-1β (IL-1β) and declined levels of acetylcholine (ACh) and dopamine (DA) in the serum (P0.01). Compared with the model group, the BXT-L, BXT-M, and BXT-H groups showed lowered levels of TNF-α and IL-1β in the serum (P0.05) and elevated levels of ACh and DA (P0.05). ConclusionBXT may ameliorate cognitive dysfunction in the rat model of VD by down-regulating the AGE/RAGE signaling pathway, reducing neuroinflammatory responses, and regulating neurotransmitter levels.

Insomnia is a sleep disorder characterized by difficulty in falling asleep, sleep maintenance disorder and impaired daytime function. Its pathological mechanism involves multiple factors such as nerve excitability, circadian rhythm, cell apoptosis, oxidative stress injury. As a classical tyrosine kinase signaling pathway, phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt) triggers Akt phosphorylation cascade, inducing inflammatory response, apoptosis, autophagy, oxidative damage, nerve excitability, and circadian rhythm imbalance. Traditional Chinese medicine(TCM) can improve sleep by targeting the PI3K/Akt pathway. Based on this, this paper systematically reviews the research progress on the regulation of PI3K/Akt pathway by traditional Chinese medicine(TCM) for insomnia at home and abroad. These drugs can regulate neuronal excitability by regulating the PI3K/Akt pathway, affect the circadian rhythm, alleviate inflammation, apoptosis, autophagy and oxidative stress, and thus regulate sleep-wake. Furthermore, literature review indicates that the PI3K/Akt signaling pathway may represent a specific pathway underlying phlegm-turbidity disturbing the upper Jiao-type insomnia.

Background Pyrethroid pesticides (PYRs) can cross the placental barrier to cause intrauterine fetal exposure, which may lead to developmental immunotoxicity (DIT). However, the specific effect of maternal PYR exposure during pregnancy on the cellular immune function of 1-year-old children remains unclear. Objective To explore the effect of PYRs exposure throughout the entire pregnancy on peripheral blood lymphocytes in 1-year-old children and potential sensitive window period of PYRs exposure. Methods A birth cohort was established by enrolling pregnant women in their first trimester and following them and their infants until one year of age. Ultra-high performance liquid chromatography-tandem mass spectrometry was used to detect the levels of PYRs metabolites, including 3-phenoxybenzoic acid (3PBA), 4-fluoro-3-phenoxybenzoic acid (4F3PBA), and cis-3-(2,2-dichlorovinyl)-2,2- dimethylcyclopropane carboxylic acid (cis-DBCA), in the urine of pregnant women during the first trimester (gestational weeks 6-12), the second trimester (gestational weeks 21-24), and the third trimester (gestational weeks 33-36). Peripheral blood leukocyte and lymphocyte counts were measured in children at 12 months of age using the Coulter principle combined with flow cytometry. Exposure levels of PYRs metabolites in each trimester were divided into low, moderate, and high exposure groups based on the 25th (P25) and 75th (P75) percentiles. Meanwhile, participants were classified as having repeated high or low exposure if their metabolite levels were > P75 or <P25 in at least two trimesters, respectively, while all others were categorized as having repeated moderate exposure. Generalized linear models were used to analyze the associations between trimester-specific and repeated PYRs metabolite exposure levels and the peripheral blood white blood cell (WBC) and lymphocyte counts in children aged 1 year. Results A total of 336 mother-child pairs were included in this study. For the pregnant women, the total detection rates of maternal urinary 3PBA, 4F3PBA, and cis-DBCA across the three trimesters of pregnancy were 80.5%, 100.0%, and 81.3%, respectively; and median creatinine-corrected concentrations were 0.24, 0.36, and 0.42 μg·g−1, respectively. In children aged 1 year, the mean WBC and lymphocyte counts in peripheral blood were (8.9±2.0)×109·L−1 and (5.7±1.6)×109·L−1, respectively. The results of the generalized linear model analysis indicated that compared to the low exposure group, the high cis-DBCA exposure group during the third trimester of pregnancy had significantly lower peripheral blood WBC count (β=−0.87, 95%CI: −1.51, −0.23) and lymphocyte count (β=−0.64, 95%CI: −1.15, −0.13); and the repeated high-exposure group of cis-DBCA had significantly lower peripheral blood WBC count (β=−1.34, 95%CI: −2.34, −0.34) and lymphocyte count (β=−0.80, 95%CI: −1.60, −0.01) than the repeated low exposure group. Similarly, the repeated moderate-exposure group of cis-DBCA had a significantly lower peripheral blood WBC count (β=−0.83, 95%CI: −1.59, −0.07) than the repeated low exposure group. Conclusion High maternal exposure to PYRs with cis-DBCA as the major metabolite exposure is associated with decreased peripheral leukocyte and lymphocyte counts in children aged 1 year, and repeated high-level exposure throughout gestation appears to exacerbate DIT in offspring. The third trimester of pregnancy maybe a sensitive window for children's DIT induced by exposure to PYRs during pregnancy.

Thyroid diseases are common clinical endocrine disorders, and their pathogenesis is generally considered to be closely related to genetic predisposition factors, immune system disorders, hormone levels, etc. Xiaoyaosan is widely used in the treatment of various thyroid diseases with excellent effects. This study summarized the relevant literature on the treatment of thyroid diseases with modified Xiaoyaosan prescriptions and their active ingredients from aspects such as theoretical analysis, clinical research, and mechanism research. Theoretical analysis revealed that Xiaoyaosan could not only disperse stagnated liver qi but also replenish deficient spleen Qi, which was consistent with the etiology and pathogenesis of thyroid diseases. Clinical studies found that Xiaoyaosan and its modified prescriptions could be widely used in the treatment of multiple thyroid diseases, such as hyperthyroidism, Hashimoto's thyroiditis, and thyroid nodules. Both the use of modified Xiaoyaosan alone and in combination with medications such as methimazole, propylthiouracil, and euthyrox could effectively improve patients' clinical symptoms. In the mechanism research, this study discovered that the whole formula of Xiaoyaosan and its modified prescriptions could inhibit inflammatory reactions, regulate immune balance, and delay liver damage during the treatment of thyroid diseases. The research on Xiaoyaosan for treating thyroid diseases mainly focused on thyroid cancer, autoimmune thyroiditis, hyperthyroidism, and hypothyroidism. The mechanisms of action mainly involved promoting cell apoptosis, inhibiting cell proliferation and migration, arresting the cell cycle, and regulating thyroid hormone levels. In conclusion, this study systematically combs and summarizes the research status of Xiaoyaosan in treating thyroid diseases through literature retrieval, aiming to provide new perspectives and new ideas for the prevention and treatment of thyroid diseases with traditional Chinese medicine.

To explore the correlation between human body fat distribution and carotid athero-sclerosis. Adult healthy individuals who underwent physical examinations at the Health Management Center of the International Medical Department(Xidan Campus) of Peking Union Medical College Hospital between January 2020 and January 2023 were selected as study participants. Baseline data, laboratory indicators, Inbody body composition analysis, and carotid ultrasound examination results were collected. Participants were divided into carotid atherosclerosis group and control group based on carotid ultrasound examination results. Baseline data, laboratory indicators, and body composition differences between the two groups were compared, and multivariate Logistic regression analysis was conducted to investigate the correlation between carotid atherosclerosis and body composition. To further explore the correlation between fat distribution and carotid atherosclerosis, the ratio of trunk fat to limb fat(trunk fat/limb fat), visceral fat area, and waist-to-hip ratio were stratified into Q1, Q2, Q3, and Q4 groups(with Q1 group as the reference) based on quartiles(Q1 to Q4), and a forest plot was constructed to analyze the risk of carotid atherosclerosis in each subgroup. A total of 2221 participants were included in this study, including 1194 males(53.76%) and 1027 females(46.24%), with a mean age of(50.28±10.93) years. There were 1049 cases in the carotid atherosclerosis group and 1172 cases in the control group. Baseline data analysis showed that the carotid atherosclerosis group had a higher age and male proportion compared to the control group(both There is a significant correlation between trunk fat/limb fat and the occurrence of carotid atherosclerosis. In the future, the sample size should be expanded, and more precise methods for measuring fat distribution should be adopted to validate the conclusions of this study.

Objective:To assess the efficacy and safety of azacitidine combined with lenalidomide in MDS patients and explore potential mechanisms of therapeutic response.Methods:Sixteen MDS patients with TP53 mutations received azacitidine plus lenalidomide at ZhongDa Hospital, Southeast University (January 2021–June 2025). Efficacy and safety were assessed, and TP53 mutation status was correlated with treatment response. Whole-transcriptome sequencing and bioinformatics were used to explore molecular biomarkers associated with therapeutic efficacy.Results:Sixteen patients (median age 69.5 years, range 52–82; 8 males, 8 females) were enrolled. According to the Molecular International Prognostic Scoring System (IPSS-M), 1, 2, and 13 patients were classified as median low, high, and very high risk, respectively. Among 16 TP53-mutated patients, 11 had biallelic mutations and 5 had monoallelic mutations. Overall response rate was 56.3% (9/16), composite complete remission rate (CRc) was 31.3% (5/16), and hematology improvement rate was 25% (4/16). Among TP53-mutated patients, the response rate was 56.3% (9/16), with variant allele frequency dropping from 65.6% to 16.5% in responders ( P=0.017). In patients with TP53 mutations and complex karyotype, response rate was 53.8% (7/13), with 57.1% (4/7) showing disappearance of CK post-treatment. The most common grade 3–4 nonhematologic adverse events were infections (9/16, 56.3% ), including pneumonia (4/16, 25.0% ), gastrointestinal infections (3/16, 18.8% ), perianal infections (1/16, 6.3% ) and sepsis (1/16, 6.3% ). High CBX8 expression may be linked to treatment response. Conclusion:Azacitidine plus lenalidomide is an effective and safe therapy for MDS, including patients with TP53 mutations and complex karyotypes. Treatment markedly reduces TP53 variant allele frequency in responders, and high CBX8 expression may predict therapeutic response.

OBJECTIVE:
To analyze the time characteristics of the Ethos online adaptive radiotherapy (OART) process in clinical practice and provide guidance for the comprehensive optimization of each stage of adaptive radiotherapy.
METHODS:
The study involved 61 patients with cervical, rectal, gastric, lung, esophageal, and breast cancers who underwent Ethos OART. The mean ± standard deviation of segmental time, total time, and target volume for these patients were tracked. The time characteristics for different cancer types were evaluated, and the average time for target and organ at risk (OAR) modifications was compared with the average target volume for each cancer type.
RESULTS:
Cervical cancer born the longest total treatment time, while breast cancer had the shortest. For all cancer types except breast cancer, the modification time for target and OAR was the most time-consuming segment. The average time for target and OAR modifications aligned with the trend of the average target volume.
CONCLUSION
The total treatment time for various cancers ranges from 15 to 35 minutes, indicating room for improvement.
