ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

ObjectiveTo investigate the possible mechanism of action of Xibining Formula (膝痹宁) for cartilage damage in knee osteoarthritis (KOA) through the cyclic guanosine-adenosine monophosphate synthase (cGAS)- stimulator of interferon genes (STING) signaling pathway. MethodsFifty C57BL/6J mice were randomly divided into five groups (10 per group), sham operation group, KOA model group, low-dose Xibining Formula group, high-dose Xibining Formula group, and high-dose Xibining Formula + agonist group. The KOA models were constructed using the destabilization of the medial meniscus (DMM) method in all groups but the sham surgery group. Two weeks after surgery, the low- and high-dose Xibining Formula groups were administered Xibining Formula at doses of 3.58 g/(kg·d) and 14.32 g/(kg·d) respectively via gavage. The high-dose Xibining Formula + agonist group received 14.32 g/(kg·d) of Xibining Formula via gavage followed by an intraperitoneal injection of Vadimezan (DMXAA) at 25 mg/kg. The sham surgery group and the KOA model group mice were given an equivalent volume of normal saline at 5 ml/(kg·d) via gavage, once daily for four consecutive weeks. Serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) were measured by ELISA; pathological changes in cartilage tissue were observed using hematoxylin-eosin (HE) staining and Safranin O-Fast Green staining. Pathological changes were scored according to the Mankin scoring system; the levels of cartilage tissue matrix regulation-related indicators such as matrix metalloproteinase 3 (MMP3), matrix metalloproteinase 13 (MMP13), a disintegrin and metalloproteinase with thrombospondin motifs 5 (ADAMTS), type-Ⅱ collagen (CⅡ) and aggregated proteoglycan (Aggrecan), and also cGAS-STING pathway-related protein and mRNA expression levels were detected by Western blot and qPCR methods. ResultsCompared with the sham surgery group, the KOA model group showed severe cartilage edge destruction, significantly increased Mankin scores, significantly decreased protein and mRNA expression levels of COLⅡ and Aggrecan, and significantly increased protein and mRNA expression levels of cGAS, STING, MMP3, MMP13, and ADAMTS5 (P<0.01). Compared with the control group, serum level of IL-6, IL-1β, TNF-α in all the intervented groups decreased (P<0.01), while compared with high-dose Xibining Formula group, level of IL-6, IL-1β, and TNF-α in low-dose Xibining Formula group and high-dose Xibining Formula + agonist group increased (P<0.01). Compared with the KOA model group, all the intervention groups exhibited alleviated cartilage pathological changes, signi-ficantly reduced Mankin scores, significantly increased protein and mRNA expression levels of COLⅡ and Aggrecan, and significantly decreased protein and mRNA expression levels of cGAS, STING, MMP3, MMP13, and ADAMTS5 (P<0.01). Compared with high-dose Xibining Formula group, high-dose Xibining Formula + agonist group showed cartilage edge destruction, significantly increased Mankin scores, significantly decreased protein and mRNA expression levels of COLⅡ and Aggrecan, and increased protein and mRNA expression levels of cGAS, STING, MMP3, MMP13, and ADAMTS5 (P<0.01). ConclusionXibining Formula may improve KOA cartilage damage by inhibiting the cGAS-STING signaling pathway, decreasing matrix degradation-related proteins, and elevating matrix composition-related proteins.

Chemotherapy-induced peripheral neurotoxicity (CIPN) is a severe dose-limiting adverse event of chemotherapy. Presently, the mechanism underlying the induction of CIPN remains unclear, and no effective treatment is available. In this study, through metabolomics analyses, we found that nab-paclitaxel therapy markedly increased serum serotonin [5-hydroxtryptamine (5-HT)] levels in both cancer patients and mice compared to the respective controls. Furthermore, nab-paclitaxel-treated enterochromaffin (EC) cells showed increased 5-HT synthesis, and serotonin-treated Schwann cells showed damage, as indicated by the activation of CREB3L3/MMP3/FAS signaling. Venlafaxine, an inhibitor of serotonin and norepinephrine reuptake, was found to protect against nerve injury by suppressing the activation of CREB3L3/MMP3/FAS signaling in Schwann cells. Remarkably, venlafaxine was found to significantly alleviate nab-paclitaxel-induced CIPN in patients without affecting the clinical efficacy of chemotherapy. In summary, our study reveals that EC cell-derived 5-HT plays a critical role in nab-paclitaxel-related neurotoxic lesions, and venlafaxine co-administration represents a novel approach to treating chronic cumulative neurotoxicity commonly reported in nab-paclitaxel-based chemotherapy.

Existing studies have underscored the pivotal role of N-acetyltransferase 10 (NAT10) in various cancers. However, the outcomes of protein-protein interactions between NAT10 and its protein partners in head and neck squamous cell carcinoma (HNSCC) remain unexplored. In this study, we identified a significant upregulation of RNA-binding protein with serine-rich domain 1 (RNPS1) in HNSCC, where RNPS1 inhibits the ubiquitination degradation of NAT10 by E3 ubiquitin ligase, zinc finger SWIM domain-containing protein 6 (ZSWIM6), through direct protein interaction, thereby promoting high NAT10 expression in HNSCC. This upregulated NAT10 stability mediates the enhancement of specific tRNA ac4C modifications, subsequently boosting the translation process of genes involved in pathways such as IL-6 signaling, IL-8 signaling, and PTEN signaling that play roles in regulating HNSCC malignant progression, ultimately influencing the survival and prognosis of HNSCC patients. Additionally, we pioneered the development of TRMC-seq, leading to the discovery of novel tRNA-ac4C modification sites, thereby providing a potent sequencing tool for tRNA-ac4C research. Our findings expand the repertoire of tRNA ac4C modifications and identify a role of tRNA ac4C in the regulation of mRNA translation in HNSCC.

Background::Liver cancer is largely resistant to chemotherapy. This study aimed to identify the effective chemotherapeutics for β-catenin-activated liver cancer which is caused by gain-of-function mutation of catenin beta 1 ( CTNNB1), the most frequently altered proto-oncogene in hepatic neoplasms. Methods::Constitutive β-catenin-activated mouse embryonic fibroblasts (MEFs) were established by deleting exon 3 ( β-cateninΔ(ex3)/+ ), the most common mutation site in CTNNB1 gene. A screening of 12 widely used chemotherapy drugs was conducted for the ones that selectively inhibited β-cateninΔ(ex3)/+ but not for wild-type MEFs. Untargeted metabolomics was carried out to examine the alterations of metabolites in nucleotide synthesis. The efficacy and selectivity of methotrexate (MTX) on β-catenin-activated human liver cancer cells were determined in vitro. Immuno-deficient nude mice subcutaneously inoculated with β-catenin wild-type or mutant liver cancer cells and hepatitis B virus ( HBV); β-cateninlox(ex3)/+ mice were used, respectively, to evaluate the efficacy of MTX in the treatment of β-catenin mutant liver cancer. Results::MTX was identified and validated as a preferential agent against the proliferation and tumor formation of β-catenin-activated cells. Boosted nucleotide synthesis was the major metabolic aberration in β-catenin-active cells, and this alteration was also the target of MTX. Moreover, MTX abrogated hepatocarcinogenesis of HBV; β-cateninlox(ex3)/+ mice, which stimulated concurrent Ctnnb1-activated mutation and HBV infection in liver cancer. Conclusion::MTX is a promising chemotherapeutic agent for β-catenin hyperactive liver cancer. Since repurposing MTX has the advantages of lower risk, shorter timelines, and less investment in drug discovery and development, a clinical trial is warranted to test its efficacy in the treatment of β-catenin mutant liver cancer.

[Objective]To explore the regulatory mechanism of hypoxia exposure on carbon metabolism pathway in spleen of mice.[Methods]C57BL/6 mice were raised at altitudes of 400 m and 4 200 m,with 5 mice in each group.After 30 days,spleen tissues were aseptically removed for analysis of differentially expressed genes,proteins,and metabolites using transcriptome sequencing,proteomics,and non-targeted metabolomics.GO and KEGG enrichment analysis were conducted to explore key pathways.The key genes and protein in the pathway were validated by RT-qPCR and Western blot.[Results]Transcriptome sequencing revealed a significant difference in the expression of 4 213 genes in hypoxic exposure,of which 1 947 were up-regulated and 2 266 were down-regulated.The analysis of differentially expressed proteins showed that 166 proteins were up-regulated and 39 proteins were down-regulated.The results of non-targeted metabolomics showed that 133 different metabolites were screened under high altitude hypoxia condition,of which 95 were up-regulated and 38 were down-regulated.KEGG enrichment analysis showed that differentially expressed genes,differentially expressed proteins and differentially expressed metabolites were enriched into the carbon metabolic pathway.Therefore,the key genes and proteins in the carbon metabolic pathway were verified.The mRNA and protein expressions of PGAM2、ENO3、PRPS2、PGLS、RPE、IDH3A、SUCLA2 and MDH2 were significantly down-regulated in the carbon metabolism pathway.[Conclusion]Low oxygen environment at high altitude weakens glycolysis,tricarboxylic acid cycle and pentose phosphate pathway by inhibiting the carbon metabolism pathway of the body,resulting in oxidative stress and energy metabolism imbalance.

Objective:To investigate the clinicopathological features, diagnosis and differential diagnosis of pseudocarcinomatous hyperplasia of the fallopian tubes.Methods:Sixteen cases of pseudocarcinomatous hyperplasia of the fallopian tubes diagnosed at Obstetrics and Gynecology Hospital of Fudan University from January 2011 to January 2024 were collected.The pathological sections were reviewed, the clinical and pathological data were consulted, and immunohistochemical examination was conducted along with follow-up.Results:The patients were aged from 19 to 57 years, with an average age of 41 and a median age of 38. Among the 16 cases, 4 were located in the right fallopian tubes, 6 in the left fallopian tubes, while the remaining cases presented bilaterally. The general manifestations were tubal edema, crispness and purulent secretion in the lumen. Morphologically, the fallopian tube mucosa exhibited a significant infiltration of neutrophils, lymphocytes and plasma cells. The epithelial cells of the fallopian tube displayed evident proliferation, stratification and disorganized arrangement leading to formation of small glandular cavity with back-to-back, fissure-like and sieve-like structures. Immunohistochemical analysis revealed positivity for CK7 and WT1, along with wild-type p53 expression, Ki-67 index ranged from 5% to 20%. During the follow-up period ranging from 1 to 156 months, all the patients remained free of disease.Conclusions:Pseudocarcinomatous hyperplasia of the fallopian tube is a rare non-neoplastic lesion, which can lead to epithelial hyperplasia and atypical hyperplasia. The most important significance of recognizing this lesion lies in avoiding misdiagnosis of fallopian tube cancer during intraoperative and postoperative pathological examination. This ensures that clinicians can administer correct clinical interventions.
