ObjectiveBased on the theory of "spleen governing transportation and transformation", this study investigates the efficacy of Atractylodis Macrocephalae Rhizoma processed with Aurantii Fructus Immaturus juice(AMR-AFI) in improving slow-transit constipation(STC), as well as the synergistic regulatory mechanism involving the microbiota-metabolism axis, thereby elucidating the scientific basis of its processing theory. MethodsAnimals were randomly divided into the control group, model group, positive drug(mosapride) group(3 mg·kg-1), and low-, medium-, and high-dose groups of AMR-AFI(3.9, 7.8, 15.6 g·kg-1). Except for the control group, the remaining five groups were induced with STC using loperamide hydrochloride. Following modeling, interventions were administered. All groups received continuous administration for 15 d, during which fecal samples, colon tissue, and serum were collected. Constipation improvement was assessed by measuring fecal moisture content and small intestinal propulsion rate, histological morphology of colonic tissue was observed via hematoxylin-eosin(HE) staining, and the levels of interleukin(IL)-6, tumor necrosis factor(TNF)-α, and IL-2 in serum were detected using enzyme-linked immunosorbent assay(ELISA). Furthermore, the microbial community structure in mouse feces was analyzed by 16S rRNA sequencing, while transcriptomic sequencing was employed to screen differentially expressed genes in colonic tissue, followed by gene ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses. Finally, Spearman correlation analysis was conducted to explore the association between differential microbiota and differential genes. ResultsCompared with the control group, the intestinal propulsion rate and fecal moisture content in the model group were significantly decreased(P<0.01), while serum levels of IL-6, TNF-α, and IL-2 were significantly elevated(P<0.01). HE staining showed damage and shedding of colonic mucosal epithelial cells, along with a reduction in goblet cells in the model group. In comparison with the model group, all treatment groups improved the pathological state of the colonic mucosa to varying degrees and reduced serum levels of IL-6, TNF-α, and IL-2(P<0.01). Among these, the high-dose group of AMR-AFI significantly increased the intestinal propulsion rate and fecal moisture content of rats(P<0.05, P<0.01). Further transcriptomic analysis revealed that a total of 104 differentially expressed genes were identified from comparisons between the model group and the control group, as well as between the model group and the high-dose group of AMR-AFI. These genes were mainly enriched in pathways closely related to STC pathogenesis, such as arachidonic acid metabolism and aldosterone-regulated sodium reabsorption. 16S rRNA sequencing results indicated that AMR-AFI reversed the structural imbalance of the gut microbiota in model mice, increased species richness, downregulated the relative abundance of pro-inflammatory bacteria such as Parasutterella, and enriched beneficial and butyrate-producing bacteria, including Lachnospiraceae_NK4A136_group, Ruminococcaceae, and Lachnospiraceae. Spearman correlation analysis further showed that the beneficial bacteria enriched in the AMR-AFI group were negatively correlated with genes involved in the arachidonic acid metabolic pathway and positively correlated with genes in the aldosterone-regulated sodium reabsorption pathway. In contrast, pro-inflammatory bacteria in the model group exhibited the opposite correlation trends. ConclusionAMR-AFI can effectively exert synergistic therapeutic effects on STC by regulating intestinal microbiota, arachidonic acid-mediated inflammatory metabolism, and aldosterone-regulated water-salt balance pathways.

Objective:
To develop a prediction model for mild cognitive impairment (MCI) risk among the elderly, so as to provide a tool for MCI early screening.
Methods :
From July 2022 to September 2024, a multi-stage stratified random cluster sampling method was used to recruit permanent residents aged ≥65 years from the Xinjiang Uygur Autonomous Region as study participants. Data on sociodemographic characteristics, nutritional status, body composition indices, bone mineral density, and handgrip strength were collected through questionnaires and physical examinations. Sarcopenia was defined based on appendicular skeletal muscle index and handgrip strength. MCI was assessed using the Mini-Mental State Examination, with adjustments for educational level. Participants were randomly divided into a training set and a validation set in a 7∶3 ratio. LASSO regression and multivariable logistic regression models were employed to screen for predictors and construct an MCI risk prediction model. The predictive performance of the model was evaluated using receiver operating characteristic (ROC) curve and decision curve analysis (DCA).
Results:
A total of 1 641 participants were surveyed, including 755 males (46.01%) and 886 females (53.99%). The majority of participants were aged 65-<75 years, comprising 1 154 individuals (70.32%). MCI was detected in 517 participants, corresponding to a detection rate of 31.51%. Resultsfrom LASSO regression and multivariate logistic regression analysis showed that residence (rural, OR = 2.323, 95% CI: 1.682-3.210), age (75-<85 years, OR = 1.405, 95% CI: 1.019-1.937; ≥85 years, OR = 3.655, 95% CI: 1.696-7.875), educational level (primary school, OR = 0.341, 95% CI: 0.247-0.472; junior high school, OR = 0.255, 95% CI: 0.160-0.408; high school, OR = 0.286, 95% CI: 0.154-0.531; bachelor's degree or above, OR = 0.120, 95% CI: 0.041-0.351), history of alcohol consumption (yes, OR = 3.216, 95% CI: 2.164-4.779), risk of malnutrition (yes, OR = 1.464, 95% CI: 1.064-2.014), sarcopenia (yes, OR = 3.197, 95% CI: 2.332-4.385), and waist-to-hip ratio (abnormal, OR = 1.540, 95% CI: 1.159-2.048) were identified as predictive factors for MCI among the elderly. In the training set, the area under the ROC curve, sensitivity, and specificity were 0.788, 0.719, and 0.712, respectively. In the validation set, the corresponding values were 0.784, 0.913, and 0.542, respectively. DCA demonstrated that the model provided a higher clinical net benefit for predicting MCI risk when the risk threshold probability ranged from 0.124 to 0.764.
Conclusion
The prediction model developed in this study demonstrates good discriminative ability and clinical utility, indicating its substantial value for predicting the MCI risk among the elderly.

ObjectiveTo evaluate the antitumor activity of Periplaneta americana extract(PAE) against human-derived lung adenocarcinoma organoids(LUAD-PDOs) and to elucidate its potential mechanism based on transcriptomics. MethodsFresh tumor and adjacent normal tissues from patients with LUAD were collected to construct LUAD-PDOs and normal lung organoid(Nor-PDOs) models using 3D organoid culture technology. The effective intervention concentration of PAE was determined using the cell counting kit-8(CCK-8) assay. Experimental groups included the model group(LUAD-PDOs), normal group, model administration group(LUAD-PDOs+PAE), and normal administration group(Nor-PDOs+PAE). Hematoxylin-eosin(HE) staining was used to observe the pathological structures of PDOs, immunohistochemistry(IHC) was performed to detect the expressions of the proliferation marker Ki-67 and lung adenocarcinoma differentiation markers cytokeratin-7(CK-7) and Napsin A, TUNEL staining was applied to detect cell apoptosis. RNA sequencing(RNA-Seq) was conducted to identify differentially expressed genes(DEGs), followed by Gene Ontology(GO), Kyoto Encyclopedia of Genes and Genomes(KEGG), and Gene Set Enrichment Analysis(GSEA), alongside protein-protein interaction(PPI) network analysis to screen core mechanisms. Finally, key targets were validated by integrating external database analysis with immunofluorescence(IF). ResultsNor-PDOs and LUAD-PDOs that highly recapitulated the pathological characteristics of the primary tissues were successfully established. The CCK-8 assay determined that the effective intervention concentration of PAE was 16 g·L-1. Morphological observation showed that Nor-PDOs exhibited lumen-forming structures, whereas LUAD-PDOs displayed dense, solid structures. CCK-8 and TUNEL assays revealed that, compared with the model group, PAE intervention inhibited the proliferation of LUAD-PDOs and promoted apoptosis in LUAD cells, while showing no significant effect on the viability of Nor-PDOs. Transcriptomic analysis identified 719 DEGs that were significantly reversed after PAE intervention(347 up-regulated and 372 down-regulated)(P<0.05). GO enrichment analysis indicated that DEGs in the model administration group were significantly enriched in biological processes related to cell cycle regulation compared to the model group. KEGG pathway analysis revealed that PAE affected pathways related to proliferation and metabolism, including pathways in cancer and the p53 signaling pathway. GSEA further confirmed that PAE significantly enhanced the activity of the p53 signaling pathway(P<0.05). PPI network analysis indicated that breast cancer type 1 susceptibility protein(BRCA1) and checkpoint kinase 1(CHEK1) were the core down-regulated targets in the p53 pathway. IF verified the high expression of BRCA1 and CHEK1 in LUAD-PDOs and their significant downregulation after PAE intervention(P<0.05). Furthermore, survival analysis based on The Cancer Genome Atlas(TCGA) database indicated that low expression of BRCA1 and CHEK1 was significantly associated with prolonged overall survival in patients with LUAD(P<0.05). ConclusionPAE effectively inhibits proliferation of LUAD-PDOs and promotes their apoptosis, its anti-tumor mechanism is potentially associated with the activation of the p53 signaling pathway, with BRCA1 and CHEK1 genes likely serving as key downstream targets for the effects of PAE.

Objective To analyze the infection status and epidemic trends of soil-borne nematode infections in Yubei, Chongqing City, in 2010,2021, and 2022. Methods The local populations from four survey sites of four towns in 2010 and five sites of five towns in 2021 and 2022 were surveyed regarding their basic information using a unified form. Fecal samples of the participants were collected and tested for soil-borne nematode infections using the modified Kato-Katz thick smear method. Results In 2010, 2 049 participants were surveyed, followed by 1 000 participants in 2021 and 2022. The overall prevalence of parasitic infections declined significantly from 3.86% to 0.20%. In 2010, soil-transmitted nematode included hookworms(3.81%) and roundworms(0.29%). In 2021, the infection rates of roundworms and hookworms were 1.70% and 0.10% respectively. Notably, only Ascaris was identified in 2022(0.20%). The≥60 age group consistently exhibited the highest infection rates across all surveys, followed by the 40-59 age group. The infection rates of males in the three surveys were 3.31%,1.92%, and 0.20% respectively, and those of females were 4.37%, 1.46%, and 0.20% respectively. There was no statistically significant difference in the infection rates between males and females. Educational attainment was inversely associated with infection; in 2010, the highest prevalence was observed among those with primary education or below, whereas in 2021, illiterate or semi-literate individuals showed the highest susceptibility. The occupational distribution of infections in 2010 indicated that retirees (8.33%), farmers(4.86%), and homemakers or unemployed individuals(3.45%)were the most affected. However, in 2021 and 2022, farmers emerged as the predominant occupational group with soil-transmitted nematode infections. Conclusions The infection rate of soil-borne nematodes showed a decreasing trend in Yubei, and the infection species changed from hookworms in 2010 to Ascaris in 2022. Farmers, the elderly, and people with low education levels should continue to be the focus of preventive and control efforts.

OBJECTIVE To investigate the mechanism of Shenling baizhu san (SLBZS) in ameliorating ulcerative colitis (UC). METHODS Mice were randomly divided into normal group, model group, and low-, medium-, high-dose SLBZS groups (3, 6, 12 g/kg), with 10 mice in each group. Except for the normal group, mice in other groups were given free access to 3% dextran sulfate sodium solution for 7 days to establish UC models. Simultaneously, mice in each group were intragastrically administered corresponding medicinal liquid or double-distilled water once a day for consecutive 7 days. After the last administration, the histopathological morphology of colon tissues was observed; the serum levels of inflammatory factors including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-18 were detected; the total bile acid contents in liver, gallbladder and colon tissues were determined; the expression level of NOD-like receptor family pyrin domain-containing protein 3 (NLRP3) in colon tissues was tested. The expression levels of flora metabolism-related proteins [G protein-coupled receptor 41(GPR41),GPR43,farnesoid X receptor (FXR), G protein-coupled bile acid receptor 1 (TGR5), flavin-containing monooxygenase 3 (FMO3), cytochrome P450 family 27 subfamily A member 1 (CYP27A1), CYP7A1] in liver or colon tissues, as well as the proteins related to Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB)/NLRP3 inflammatory axis [TLR4, NF-κB, phosphorylated NF-κB (p-NF-κB), myeloid differentiation factor 88 (MyD88), NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), caspase-1] in colon tissues were measured. RESULTS Compared with the model group, the colon tissue injury and inflammatory cell infiltration were alleviated in medium- and high-dose SLBZS groups. The serum levels of TNF-α, IL-1β and IL-18, total bile acid contents in liver and colon tissues, as well as the protein expression levels of FMO3 and CYP7A1 in liver tissues, TLR4, p-NF-κB, NF-κB, MyD88, NLRP3, ASC and caspase-1 in colon tissues were significantly decreased (P<0.05). Meanwhile, the total bile acid content in gallbladder, the protein expression levels of GPR41 and GPR43 in colon tissues, along with CYP27A1, FXR and TGR5 in liver tissues were significantly increased (P<0.05). CONCLUSIONS SLBZS may relieve colonic inflammatory injury and ameliorate UC by regulating the expression of flora metabolism-related proteins and inhibiting the abnormal activation of TLR4/NF-κB/NLRP3 inflammatory axis.

ObjectiveTo observe the long-term survival outcomes and complications of liver cirrhosis patients with spontaneous portosystemic shunt and type 1 isolated gastric varices (IGV-1) bleeding after secondary endoscopic preventive therapy, and to investigate the independent influencing factors for long-term prognosis. MethodsA total of 70 liver cirrhosis patients with spontaneous portosystemic shunt and IGV-1 bleeding who were admitted to Beijing Ditan Hospital, Capital Medical University, from January 5, 2015 to November 29, 2019 were enrolled as subjects, and related baseline data were collected, including age, sex, etiology, routine blood test results, liver function parameters, renal function parameters, coagulation parameters, Child-Pugh score, and the presence or absence of comorbidities such as cholestasis, hepatocellular carcinoma, thrombosis, ascites, and hepatic encephalopathy. All patients underwent secondary endoscopic preventive therapy for rebleeding and were followed up for 5 years. The primary endpoints were ectopic embolism rate and all-cause mortality rate, and the secondary endpoints were liver-related mortality and liver-related complications. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. The Cox regression analysis was used to investigate the prognostic factors for 1-, 3-, and 5-year survival time, and the Logistic regression analysis was used to identify the independent risk factors for liver disease-related complications. ResultsThe incidence rate of ectopic embolism was 0% within 5 years of follow-up. The 1-, 3-, and 5-year all-cause mortality rates were 5.7%, 24.3%, and 32.9%, respectively. There were 2 cases of liver-related death in year 1, 8 cases in year 3, and 12 cases in year 5, resulting in a liver disease-related mortality rate of 17.14% (12/70). Compared with the survival group, the death group had significantly higher incidence rates of hepatocellular carcinoma (0.00% vs 17.39%, χ2=8.669, P=0.003) and ascites (38.30% vs 52.17%, χ2=7.272, P=0.026), and compared with the death group, the survival group had significantly lower 5-year incidence rates of rebleeding (10.64% vs 100.00%, χ2=51.383, P<0.001), ascites (8.51% vs 52.17%, χ2=21.574, P<0.001), and hepatic encephalopathy (0.00% vs 21.74%, χ2=12.029, P=0.002). The multivariate Cox regression analysis showed that during the 1-year follow-up, comorbidity with hepatocellular carcinoma before surgery (hazard ratio [HR]=14.601, 95% confidence interval [CI]: 2.049 — 104.098, P=0.007) and PT (HR=1.662, 95%CI: 1.090 — 2.535, P=0.018) were independent risk factors for survival, and HGB level (HR=0.863, 95%CI: 0.747 — 0.998, P=0.046) was a protective factor for prolonged survival; during the long-term follow-up for 3 or 5 years, preoperative comorbidities with hepatocellular carcinoma (3 years: HR=40.174, 95%CI: 8.939 — 180.559, P<0.001; 5 years: HR=26.739, 95%CI: 6.993 — 102.243, P<0.001) and ascites (3 years: HR=3.638, 95%CI: 1.751 — 7.575, P=0.001; 5 years: HR=2.555, 95%CI: 1.419 — 4.598, P=0.002) were independent risk factors for mortality. The Logistic regression analysis showed that during the follow-up for 3 years, comorbidity with ascites before surgery (odds ratio [OR]=0.255, 95%CI: 0.102 — 0.636, P=0.003) was associated with a lower risk of rebleeding, while comorbidity with hepatocellular carcinoma before surgery (OR=16.231, 95%CI: 1.298 — 202.878, P=0.031) was an independent risk factor for rebleeding; prothrombin time was a protective factor against hepatic encephalopathy (OR=0.790, 95%CI: 0.648 — 0.964, P=0.020); during the follow-up for 5 years, aggravation of ascites after surgery (OR=5.578, 95%CI: 1.474 — 21.103, P=0.011) was an independent risk factor for rebleeding, and aggravation of ascites after surgery (OR=175.046, 95%CI: 14.306 — 2 141.909, P<0.001) were independent risk factors for the development of ascites in the future. ConclusionComorbidity with hepatocellular carcinoma before surgery and prothrombin time are independent risk factors for 1-year survival, whereas a high HGB level is a protective factor for increasing 1-year survival. Preoperative comorbidities with hepatocellular carcinoma and ascites are independent risk factors for the long-term prognosis of patients with spontaneous portosystemic shunt and IGV-1 bleeding and can significantly shorten survival time. Preoperative comorbidity with ascites can reduce the occurrence of rebleeding, while postoperative hepatocellular carcinoma and aggravation of ascites after surgery are independent risk factors for rebleeding; aggravation of ascites after surgery is an independent risk factor for the development of ascites in the future.

Steroid-induced osteonecrosis of femoral head (SONFH) is a disease characterized by femoral head collapse and local pain caused by excessive use of glucocorticoids. Peroxisome proliferator-activated receptor-γ (PPARγ) is mainly expressed in adipose tissue. Wnt/β-catenin, AMPK and other related signaling pathways play an important role in regulating adipocyte differentiation, fatty acid uptake and storage. Bone marrow mesenchymal cells (BMSCs) have the ability to differentiate into adipocytes or osteoblasts, and the use of hormones upregulates PPARγ expression, resulting in BMSCs biased towards adipogenic differentiation. The increase of adipocytes affects the blood supply and metabolism of the femoral head, and the decrease of osteoblasts leads to the loss of trabecular bone, which eventually leads to partial or total ischemic necrosis and collapse of the femoral head. MicroRNAs (miRNAs) are a class of short non-coding RNAs that regulate gene expression by inhibiting the transcription or translation of target genes, thereby affecting cell function and disease progression. Studies have shown that miRNAs affect the progression of SONFH by regulating PPARγ lipid metabolism-related signaling pathways. Therefore, it may be an accurate and feasible SONFH treatment strategy to regulate adipogenic-osteoblast differentiation in BMSCs by targeted intervention of miRNA differential expression to improve lipid metabolism. In this paper, the miRNA-mediated PPARγ-related signaling pathways were classified and summarized to clarify their effects on lipid metabolism in SONFH, providing a theoretical reference for miRNA targeted therapy of SONFH, and then providing scientific evidence for SONFH precision medicine.

Alzheimer's disease (AD) is the commonest neurodegenerative disease that causes memory decline, cognitive dysfunction and behavior disorders in the aged people. Primary pathological hallmarks of AD include amyloid-β (Aβ), neurofibrillary tangles (NFTs), gliosis, and neuronal loss. Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels have important physiological functions, especially in aspects of controlling the resting membrane potential, pacemaker activity, memory formation, sleep and arousal. This article reviews the structure, distribution, regulation of HCN channels and the role of HCN channels in the pathological mechanisms of AD, aiming to provide drug therapeutic targets for the prevention and treatment of AD.

The thought of medicine and food homology and substances with both edible and medicinal values are an important part of China's excellent traditional culture and medicine treasure, playing an important role in human diet and health maintenance for thousands of years. Substances with both edible and medicinal values are a standardized name governed by existing regulations, and many substances with both edible and medicinal values in the list lack important information such as original plants and edible and medicinal parts. Some substances change as the relevant regulations change, which confuses the use and regulation. According to the definition and inclusion conditions of substances with both edible and medicinal values in the Regulation of Substances with Both Edible and Medicinal Values Catalogue, this paper comprehensively reviewed the first batch of 87 substances with both edible and medicinal values published in 2002 by collecting information and investigating the practical application. Some substances supplemented, deleted, and revised were analyzed and discussed, and a complete revised list was compiled, encompassing a total of 90 substances, which were when combined with the 19 substances of the last three batches(published in 2019, 2023, and 2024), amounted to a total of 109 substances. In addition, the substances not currently in the published list but have both edible and medicinal values according to the latest definition were summarized, which revealed at least 27 other substances. Therefore, there were at least 136 substances with both edible and medicinal values. Additionally, the potential substances that could be included in the list of substances with edible and medicinal values were prospected, providing a focus for future expansion of the list. This paper systematically reviewed and revised the list of substances with both edible and medicinal values to lay a foundation for the regulatory authorities to revise the catalog of these substances and provide basic information for promoting the new quality productive forces in the health field and boosting the orderly and rapid development of the big health industry.
