Liumotang comes from the Yuan dynasty's Effective Prescription Handed Down for Generations of Physicians. It is composed of six medicinal materials: Arecae Semen, Aquilariae Lignum Resinatum, Aucklandiae Radix, Linderae Radix, Rhei Radix et Rhizoma, and Aurantii Fructus. It is a classical formula for treating abdominal pain due to Qi stagnation and constipation accompanied by heat. This study systematically collated the records of Liumotang in ancient medical books and modern clinical literature and conducted in-depth analysis and textual research on its formula source, main diseases, composition, dosage, medical books, container capacity, processing, preparation method, usage, drug basis, formula meaning, and other key information, so as to provide a powerful reference for the development and clinical application of compound preparations of the classical formula Liumotang. The results show that Liumotang was first seen in Effective Prescription Handed Down for Generations of Physicians, and many medical books of the past dynasties have imitated this. In terms of drug basis, the dried and mature seeds of the palm plant Areca catechu, resin-containing wood of the Daphneaceae plant Aquilaria sinensis, the dried roots of the Asteraceae plant woody Aucklandia lappa, the dried tuber root of the Lauraceae plant Lindera aggregata, the dried roots and rhizomes of the knotweed plant, R. palmatum, R.tangutikum, and R. officinale, and the dried and unripe fruits of the citrus genus C. aurantium and its cultivated varieties from the family Rutaceae were selected. In terms of dosage, through the textual research on bowls in the Ming and Qing dynasties, combined with the conversion of medicines and bowl capacity in the Qing dynasty, it was estimated that the dosage of each drug in the Yuan dynasty was 10.86 g. In the Ming and Qing dynasties, the dosage of drugs was mostly equal, but the dosage of drugs was somewhat different. In terms of processing, preparation method, and usage, in the medical books of the past dynasties, the processing of drugs has slightly changed, but raw drugs are used in all preparations. The preparation method and usage did not change much during the Yuan, Ming, and Qing dynasties, except for certain differences in dosage. In terms of syndrome, Liumotang was first used to treat abdominal pain due to Qi stagnation and constipation accompanied by heat. Medical books of the past dynasties often omit the symptoms of heat. In modern clinical practice, Liumotang is mainly used in the digestive system and urinary system diseases and is mostly used to treat constipation-predominant irritable bowel syndrome, biliary reflux gastritis, functional constipation, slow transit constipation, and other diseases, with no adverse reactions found yet. The above results provide a reliable scientific basis for the development and clinical treatment of Liumotang compound preparations.

OBJECTIVE To investigate the ameliorative effect and potential mechanism of imperatorin (IMP) on doxorubicin (DOX) resistance in breast cancer. METHODS The effects of maximum non-toxic concentration (100 μg/mL) of IMP combined with different concentrations of DOX (12.5, 25, 50, 75, 100 μg/mL) on the proliferation of MCF-7/DOX cells were determined by MTT method. MCF-7/DOX cells were divided into blank control group (1‰ dimethyl sulfoxide), DOX group (50 μg/mL), IMP+DOX group (100 μg/mL IMP+50 μg/mL DOX) and IMP group (100 μg/mL). mRNA and protein expressions of multidrug resistance protein 1 (MDR1) and multidrug resistance-associated protein 1 in each group were measured. The relevant pathways and targets involved in the improvement of DOX resistance in breast cancer cells by IMP were screened and validated by using transcriptome sequencing technology, along with gene ontology (GO) enrichment analyses and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. RESULTS Compared with DOX alone, the combination of IMP and DOX reduced the half inhibitory concentration of DOX on MCF-7/DOX cells from 81.965 μg/mL to 43.170 μg/mL, the reverse fold was 1.90, and the mRNA expression of MDR1 was significantly down-regulated (P<0.05). The results of GO enrichment analyses and KEGG pathway enrichment analyses indicated that the reversal of DOX resistance in breast cancer by IMP was mainly associated with the regulation of biological processes such as detoxification, multiple biological processes, and cell killing. The main pathway involved was the p53 signaling pathway, and the key targets mainly included constitutively photomorphogenic protein 1 (COP1), cyclin E1 (CCNE1), growth arrest and DNA damage-inducible protein 45A E-mail:tangxilan1983@163.com (GADD45A) and GADD45B. The results of the verification experiments showed that compared with DOX group, there was a trend of up-regulation of COP1 mRNA, and significant down- regulation of CCNE1, GADD45A, and GADD45B mRNA expression in IMP+DOX group (P<0.05). CONCLUSIONS The effect of IMP in ameliorating DOX resistance in breast cancer is related to its regulation of COP1, CCNE1, GADD45A and GADD45B targets in the p53 signaling pathway.

Objective:
To evaluate the comprehensive intervention effect of lunch for primary and secondary school students in Minhang District, so as to provide a theoretical and practical basis for lunch intervention in school.
Methods:
From October to December 2023, a convenience sampling method was used to select 1 937 students from one primary and secondary school in Minhang District.A comprehensive intervention measure focusing on "reducing oil and salt" for lunch recipe optimization and nutrition education was carried out, and a questionnaire survey was conducted to evaluate the intervention effect three months later. Chi square test and Wilcoxon rank test were used to compare the data before and after the intervention.
Results:
After intervention, the use of cooking oil and salt, the supply of protein and fat in primary and secondary school lunches were reduced, and had no obvious impact on energy and other major nutrients. After intervention, compared to before intervention, the proportion of primary school students who felt that lunch was greasy decreased (8.9%, 6.2%, χ 2=4.35), and the proportion of primary and secondary school students who felt that lunch were delicious decreased significantly (33.2%, 23.2%; 63.9%, 53.5%, χ 2=26.39, 17.52) ( P < 0.05 ). Secondary school students also felt reduced variety of food ingredients (46.9%, 38.3%, χ 2=16.05, P <0.05). In addition, after intervention, the total surplus rate of primary school students meals decreased (7.4%, 4.4%, χ 2=5.73), mainly reflected in the decrease of the surplus rate of staple foods (7.1%, 2.4%, χ 2=17.39), while the surplus rate of vegetable dishes increased ( 16.0 %, 21.2%, χ 2=6.01) ( P <0.05). Although there was no significant change in the total surplus rate of meals for secondary school students, the surplus rate of staple foods decreased (12.9%, 5.4%, χ 2=33.52), while the surplus rates of meat and vegetable dishes increased (11.2%, 26.9%; 17.5%, 33.2%, χ 2=74.26, 61.88) ( P <0.05). After intervention, there was no statistically significant difference in the overweight and obesity rates of primary school students ( χ 2=0.11,0.43) and secondary school students ( χ 2=0.01,0.00) compared to before intervention( P >0.05). After intervention, the lung capacity of primary school students [1 564 (1 269,1 890) mL] and sitting forward flexion [11.3 (7.6, 15.2) cm] increased compared to before intervention [1 522 (1 259, 1 819 ) mL, 10.5 (6.3, 13.5) cm] ( Z =2.20, 4.68, P <0.01), but there was no statistically significant difference in lung capacity and sitting forward flexion of secondary school students before and after intervention ( Z =-0.46, -0.08, P >0.05).
Conclusion
The comprehensive intervention of school lunch has promoted a significant decrease in the use of oil and salt in lunch and improved the quality of recipes, and has a positive impact on the situation of leftover lunch and the health of students to a certain extent.

ObjectiveTo investigate the effect and mechanism of Yijingtang (YJT) in treating diminished ovarian reserve (DOR) in rats by regulating the Toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-κB (NF-κB) signaling pathway. MethodsFifty female SD rats with normal estrous cycles were randomly allocated into blank, model, low- and high-dose (12.579 and 25.158 g·kg-1, respectively) YJT, and dehydroepiandrosterone (7.487 5 mg·kg-1) groups, with 10 rats in each group. The rats in other groups except the blank group were administrated with the tripterygium glycosides tablet suspension (5 mg·kg-1) by gavage for 14 days for the modeling of DOR. The rats in the drug treatment groups were administrated with corresponding drugs by gavage from day 15 for 30 consecutive days, and those in the blank and model groups received equal volumes of distilled water. The vaginal exfoliated cell smears were observed to assess the changes in the estrous cycle. The wet weight of bilateral ovaries was weighed for calculation of the ovarian index. Hematoxylin-eosin staining was performed to observe the histopathological changes in the ovaries and the proportions of follicles at various levels were calculated. The serum levels of sex hormones [follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and anti-Müllerian hormone (AMH)] and inflammatory factors [tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), and interleukin-10 (IL-10)] were determined by enzyme-linked immunosorbent assay. Real-time quantitative polymerase chain reaction(Real-time PCR) was conducted to determine the mRNA levels of TLR4, MyD88, NF-κB profilin α (IκBα), NF-κB and inflammatory factors in the ovarian tissue. Western blot was employed to measure the protein levels of factors related to the TLR4/MyD88/NF-κB signaling pathway in the ovarian tissue. Immunofluorescence (IF) was used to detect the nuclear translocation of NF-κB p65 in the ovarian tissue. ResultsCompared with the blank group, the model group showed disturbed estrous cycles, increased inflammatory infiltration in the ovarian tissue, decreases in ovarian index and proportion of presinusoidal follicles, and an increase in the proportion of atretic follicles (P<0.05, P<0.01). In addition, the model group showed elevated serum levels of FSH, LH, TNF-α, and IL-1β, up-regulated mRNA levels of TLR4, MyD88, IκBα, NF-κB, TNF-α, and IL-1β and protein levels of TLR4, MyD88, p-IκBα, and p-NF-κB p65 (P<0.01), lowered serum levels of AMH, E2, and IL-10, down-regulated mRNA level of IL-10 (P<0.01), and massive nuclear translocation of NF-κB p65 in the ovarian tissue. Compared with the model group, dehydroepiandrosterone and low and high doses of YJT restored the disturbed estrous cycle, reduced inflammatory infiltration in the ovarian tissue, increased the ovarian index (P<0.01), and changed the follicular composition ratio (P<0.01). Furthermore, the drugs lowered the serum levels of FSH, LH, TNF-α, and IL-1β, down-regulated the mRNA levels of TLR4, MyD88, IκBα, NF-κB, TNF-α, and IL-1β and the protein levels of TLR4, MyD88, p-IκBα, and p-NF-κB p65 (P<0.05, P<0.01), raised the serum levels of AMH, E2, and IL-10, up-regulated the mRNA level of IL-10 (P<0.05, P<0.01), and reduced the nuclear translocation of NF-κB p65 in the ovarian tissue. ConclusionYJT may inhibit the release and expression of inflammatory factors by regulating the TLR4/MyD88/NF-κB signaling pathway to attenuate the inflammatory responses in the ovarian tissue, thereby improving the ovarian function in DOR rats.

ObjectiveThis study aimed to explore the effects of aerobic exercise on cognitive function in aging mice and to elucidate the underlying molecular mechanisms by which aerobic exercise ameliorates cognitive decline through the regulation of gut microbiota-metabolite network. By providing novel insights into the interplay between exercise, gut microbiota, and cognitive health, this research seeks to offer a robust theoretical foundation for developing anti-aging strategies and personalized exercise interventions targeting aging-related cognitive dysfunction. MethodsUsing naturally aged C57BL/6 mice as the experimental model, this study employed a multi-omics approach combining 16S rRNA sequencing and wide-targeted metabolomics analysis. A total of 18 mice were divided into 3 groups: young control (YC, 4-month-old), old control (OC, 21-month-old), and old+exercise (OE, 21-month-old with 12 weeks of moderate-intensity treadmill training) groups. Behavioral assessments, including the Morris water maze (MWM) test, were conducted to evaluate cognitive function. Histopathological examinations of brain tissue sections provided morphological evidence of neuronal changes. Fecal samples were collected for gut microbiota and metabolite profiling via 16S rRNA sequencing and ultra-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UPLC-QTOF-MS). Data were analyzed using a combination of statistical and bioinformatics tools to identify differentially abundant microbial taxa and metabolites and to construct interaction networks between them. ResultsBehavioral tests revealed that 12 weeks of aerobic exercise significantly improved spatial learning and memory capacity of aged mice, as evidenced by reduced escape latency and increased target area exploration and platform crossings in the MWM. Histopathological analysis demonstrated that exercise mitigated aging-related neuronal damage in the hippocampus, enhancing neuronal density and morphology. 16S rRNA sequencing indicated that exercise increased gut microbiota α‑diversity and enriched beneficial bacterial genera, including Bifidobacterium, Parabacteroides, and Rikenella. Metabolomics analysis identified 32 differentially regulated metabolites between OC and OE groups, with 94 up-regulated and 30 down-regulated in the OE group when compared with OC group. These metabolites were primarily involved in energy metabolism reprogramming (e.g., L-homocitrulline), antioxidant defense (e.g., L-carnosine), neuroprotection (e.g., lithocholic acid), and DNA repair (e.g., ADP-ribose). Network analysis further revealed strong positive correlations between specific bacteria and metabolites, such as Parabacteroides with ADP-ribose and Bifidobacterium with lithocholic acid, suggesting potential neuroprotective pathways mediated by the gut microbiota-metabolite axis. ConclusionThis study provides comprehensive evidence that aerobic exercise elicits cognitive benefits in aging mice by modulating the gut microbiota-metabolite network. These findings highlight three key mechanisms: (1) the proliferation of beneficial gut bacteria enhances metabolic reprogramming to boost DNA repair pathways; (2) elevated neuroinflammation-inhibiting factors reduce neurodegenerative changes; and (3) enhanced antioxidant defenses maintain neuronal homeostasis. These results underscore the critical role of the “microbiota-metabolite-brain” axis in mediating the cognitive benefits of aerobic exercise. This study not only advances our understanding of the gut-brain axis in aging but also offers a scientific basis for developing personalized exercise and probiotic-based interventions targeting aging-related cognitive decline. Future research should further validate these mechanisms in non-human primates and human clinical trials to establish the translational potential of exercise-induced gut microbiota-metabolite modulation for combating neurodegenerative diseases.

Objective: To retrospectively analyze the early monitoring indicators before and after admission, the use of coagulation/anticoagulant medications, and the red blood cell transfusion within 24 hours in emergency trauma patients, and to identify the indicators related to the volume of red blood cells transfused during the first 24 hours of hopitalization, thereby assisting clinical judgment of the probability and required quantity of red blood cell transfusion. Methods: Data of 117 emergency trauma patients admitted to intensive care unit (ICU) from January 2022 to March 2024 were retrospectively analyzed. Patients were categorized according to whether the volume of red blood cells transfused within 24 hours exceeded specific quartile thresholds (Q1, Q2, Q3). Non-parametric tests were used for numerical variables and Chi-square tests were used for categorical variables to identify statistically significant single-factor indicators, which were subsequently incoporated into a binary logistic regression model to obtain a combined predictive probability. ROC curve analysis was performed on the multi-factor indicators and their combined predictive probability derived from the binary logistic regression model. Results: 1) The initial hemoglobin (Hb) and hematocrit (Hct) levle were independent influencing factors in the group with red blood cell transfusion volume exceeded Q1 (P<0.05), and the combined predictive probability demostrated by ROC curve analysis was AUC=0.858 (P<0.05). 2) In the group of red blood cell transfusion volume exceeding Q2, the initial Fib, transhulitic acid, human prothrombin complex, trauma category and primary trauma site were independent influencing factors (P<0.05), and the combined predictive probability of ROC curve analysis was AUC=0.966 (P<0.05). 3) Pulse pressure and trauma category were independent influencing factors in the group with red blood cell transfusion volume exceeding Q3 (P<0.05), and ROC curve analysis revealed that combined prediction probability was AUC=0.944 (P<0.05). Conclusion: Early monitoring indicators and the use of coagulation medications, before and after admission in emergency trauma patients show diagnostic value in predicting the amount of red blood cells transfused on the first day of admission. Early warning alerts established through patient monitoring indicators can reduce incidents of untimely blood supply from the blood transfusion department (blood bank) for emergency trauma patients with massive hemorrhage, especially for patients with rare blood types or during blood supply shortage.
