Objective To explore the mechanism by which zinc-regulated transporters, iron-regulated transporter-likeprotein 4 (ZIP4) regulates glycolysis and its impact on tumor progression in cholangiocarcinoma (CCA), providing a theoretical basis for targeted therapy of CCA. Methods ZIP4 expression in CCA was analyzed using the GEPIA database. Immuno-histochemistry (IHC) was used to detect ZIP4 expression in 20 paired CCA and adjacent non-tumor tissues. Stable ZIP4-overexpressing CCA cell lines (ZIP4-OE) were established. Gene set enrichment analysis was used to screen differentially expressed genes and pathways in ZIP-OE CCA cells. ZIP4, N-myc proto-oncogene protein (MYCN), and histone-lysine N-methyltransferase 2E (KMT2E) were knocked down using small interfering RNAs (siRNAs). The expression of glycolysis-related gene (glucose transporter 1 [Glut1], hexokinase 2 [HK2], and lactate dehydrogenase A [LDHA]) was measured by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). Glycolytic activity was assessed by measuring the extracellular acidification rate (ECAR). Cell proliferation was evaluated using colony formation assays, and cell migration was assessed using Transwell assays. A xenograft mouse model was constructed to examine CCA tumor growth. Protein levels of ZIP4, KMT2E, H3K4me3 (tri-methylation of lysine 4 on histone H3), and MYCN were detected by Western blotting. Results GEPIA database analysis and IHC results confirmed significantly higher ZIP4 expression levels in CCA tissues compared to adjacent non-tumor tissues (P<0.05). Compared to the control group, the ZIP4-OE group exhibited a significantly increased ECAR, along with significantly enhanced proliferation and migration abilities (P<0.01). Conversely, knockdown of ZIP4 suppressed CCA cells proliferation and migration. GEPIA analysis indicated that ZIP4 upregulates the transcription of oncogene MYCN, as well as glycolysis-related genes. Knockdown of MYCN abolished the ZIP4 overexpression-induced upregulation of Glut1, HK2, and LDHA gene transcription, reduced glycolysis, and significantly inhibited CCA cell proliferation and migration (P<0.05). Mechanistic studies demonstrated that ZIP4 increases H3K4me3 level via KMT2E, leading to MYCN transcription. Knockdown of KMT2E in CCA cells suppressed the ZIP4 overexpression-induced enhancement in H3K4me3 modification, resulting in MYCN downregulation and significantly reduced CCA cells proliferation and migration (P<0.05). Conclusions ZIP4 upregulates H3K4me3 modification through KMT2E, which recruits transcription factors to activate the transcription of MYCN. This subsequently enhances cellular glycolysis and promotes the proliferation and migration of CCA cells.

Objective: To identify biomolecular markers closely related to the occurrence of kidney renal clear cell carcinoma (KIRC) and verify their expression levels in clinical samples. Methods: Stage Ⅰ KIRC mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA).Principal component analysis (PCA) was used for dimensionality reduction to screen differentially expressed genes (DEGs),which then underwent GO and KEGG analyses.Weighted gene co-expression network analysis (WGCNA) was used to screen genes significantly related to KIRC,and a protein-protein interaction (PPI) network was constructed to screen hub genes.The diagnostic value of hub genes was evaluated with receiver operating characteristic (ROC) curve,and their prognostic value was analyzed using survival curve plots.The correlation between the mRNA expressions of hub genes and the pathological stages of KIRC was analyzed.Clinical samples of 20 patients with stage Ⅰ KIRC treated in our hospital were included,and the expressions of the hub genes in cancerous and adjacent tissues were detected with reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR),Western blotting,and enzyme-linked immunosorbent assay (ELISA). Results: A total of 8223 DEGs were screened out,including 4092 up-regulated ones and 4131 down-regulated ones.GO analysis showed that DEGs were related to bioadhesion,plasma membrane composition,and transporter activity.KEGG analysis showed that DEGs were related to pathways such as cell adhesion molecules,cytokine-cytokine receptor interactions,and interactions between viral proteins and cytokines and cytokine receptors.WGCNA analysis obtained 171 genes that were significantly related to stage Ⅰ KIRC.The hub gene,lymphocyte cytosolic protein 2 (LCP2),screened out by the PPI network,was significantly related to stage Ⅰ KIRC.The area under the ROC curve was 0.96.The expression level was negatively correlated with the overall survival rate of patients.The expression of LCP2 was related to the stage and lymph node metastasis.Clinical verification showed that the mRNA and protein relative expressions of LCP2 in KIRC tissues were significantly higher than those in adjacent tissues (P<0.000 1). Conclusion: LCP2 is significantly up-regulated in stage Ⅰ KIRC tissues and can be used as a potential biomarker for the early diagnosis and treatment of KIRC.

Asthma is a chronic inflammatory respiratory disease involving multiple cells and cellular components, characterized by recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, significantly impacting patients' quality of life. The phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt) signaling pathway, as a crucial hub in intracellular signaling, is widely involved in the regulation of cell growth, proliferation, survival, metabolism, and a series of pathophysiological processes. Its regulatory role in the pathological progression of asthma is particularly significant, specifically in promoting airway inflammation, mediating epithelial mesenchymal transition, accelerating airway remodeling, regulating cell autophagy, inducing mucus hypersecretion, and influencing immune response balance. This study analyzed potential molecular targets of the PI3K/Akt pathway, including activators such as cysteine proteinase inhibitor 1(CST1), found in inflammatory zone 1(FIZZ1) and free fatty acid receptor 1(FFAR1), and inhibitors such as human β-defensin-3(hBD-3), disintegrins, metalloproteinase 33(ADAM33) and interleukin-27(IL-27), and initially revealed the potential molecular mechanisms of traditional Chinese medicine(TCM) in asthma intervention. Based on this, the authors systematically summarized the efficacy and specific mechanisms of TCM monomers, compounds, and external treatments for asthma by regulating the PI3K/Akt signaling pathway through literature review and analysis, aiming at establishing a robust foundation for the wide application and advanced development of TCM in asthma treatment, offering innovative insights for clinical research and drug development of asthma.

Objective: To investigate the prevalence of human T-lymphotropic virus (HTLV) infection among blood donors in Hunan Province from 2022 to 2024. Methods: A total of 1 830 342 blood donors from 14 prefecture-level blood centers in Hunan Province over the past three years were screened for anti-HTLV-Ⅰ/Ⅱ using enzyme-linked immunosorbent assay (ELISA). Initially reactive samples were further tested with Line Immunoassay (LIA
)/MP-Western blot and RT-PCR nucleic acid test for confirmation. Blood donors confirmed positive for HTLV were tracked and followed up. Results: From 2022 to 2024, the initial ELISA reactive rate for anti-HTLV-I/II among blood donors in Hunan Province was 1.36 per 10 000 (249/1 830 342). The confirmed positive rate was 0.20 per 10 000 (37/1 830 342), accounting for 14.86% of the initially reactive donors. The follow-up success rate for confirmed HTLV-positive blood donors was only 18.92%, while that for HTLV-indeterminate donors was 54.17%. Conclusion: The confirmed HTLV infection rates in Yueyang, Loudi, Shaoyang, Yiyang, and Zhuzhou cities were higher than the provincial (0.20 per 10 000). Chenzhou, Yongzhou, Zhangjiajie, and Xiangxi were identified as low prevalence areas, with an infection rate of 0. The overall follow-up success rate was low, indicating significant difficulties and bottlenecks in follow-up work. The comprehensive screening for HTLV and follow-up studies in Hunan provide valuable data to further improve blood safety testing strategies and risk warning mechanisms.

To systematically review randomized controlled trials (RCTs) of traditional Chinese medicine (TCM) intervention in ulcerative colitis (UC), and analyze the characteristics of these studies and their outcome indicators, thereby providing references for the design of future RCTs of TCM intervention in UC and offering evidence supporting the clinical application of TCM in UC. A computerized search was conducted in the China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science databases for RCTs of TCM intervention in UC published from January 2021 to August 2024. The risk of bias was assessed, and outcome indicators were qualitatively analyzed. A total of 555 RCTs were included, with a sample size of 44 853 participants. The largest sample size was 218 cases, and the smallest was 28 cases, with most studies focusing on 60-100 participants. Of the 386 RCTs that explicitly reported TCM syndrome types, the top three were large intestine dampness-heat syndrome (31.05%), spleen and kidney yang deficiency syndrome (12.47%), and spleen deficiency with dampness syndrome (9.17%). The interventions, ranked by frequency of use, included internal Chinese medicine compounds/preparations (64.5%), Chinese medicine compounds/preparations with retained enema (18.2%), internal Chinese medicine compounds/preparations + external TCM treatment (5.95%), and external TCM treatment alone (4.86%). The treatment duration was mainly 4-8 weeks (64.86%), with 61 studies (10.99%) reporting follow-up time. A total of 157 outcome indicators were used, with a frequency of 3 460 occurrences, classified into six domains: TCM syndromes and symptoms (346 occurrences, 10%), symptoms/signs (541 occurrences, 15.64%), physical and chemical examinations (2 119 occurrences, 61.24%), quality of life (107 occurrences, 3.09%), long-term prognosis (61 occurrences, 1.76%), and safety events (284 occurrences, 8.21%). The analysis reveals several limitations in the outcome indicators of TCM intervention in UC, including the lack of a basis for sample size calculation, non-standardized TCM syndrome classification, absence of trial design and registration, inadequate blinding and allocation concealment, adherence issues with interventions, imbalanced selection of surrogate and endpoint indicators, inconsistency in the timing of outcome measurements, design issues that require standardization, and ethical and safety concerns. It is recommended that future studies actively construct a set of core indicators for UC that include standardized TCM syndrome classification, clear efficacy evaluation indicators, key endpoint indicators, and reasonable measurement time points. Long-term prognostic impacts, comprehensive assessments of patients' quality of life, and consideration of economic benefits should be emphasized, providing a basis for the clinical practice of TCM in the treatment of UC.

Objective:To investigate the current status of vocational training for pediatric clinical research coordinators (CRC), and discuss the construction of base-based pediatric CRC training, and to promote the ability of pediatric CRCs.Methods:From July 25 to October 16, 2023, an anonymous self-designed questionnaire survey was conducted through the Wenjuanxing platform to investigate the current situation of pediatric CRC vocational training and base training needs. The data were collated using Excel. Categorical data were described as numbers and percentages.Results:A total of 328 usable questionnaires were returned. Only 7.62% (25 people) believed that existing CRC training was sufficient and could meet actual work needs; 4.88% (16 people) responded that there was no training; 46.34% (152 people) believed that the training was insufficient to support actual work needs; 87.50% (287 people) believed that continuous CRC training was needed; 46.95% (154 people) preferred experienced CRCs for teaching, who should have at least 3 years of CRC work experience; and 46.95% (154 people) preferred a duration of 3 months for CRC training. The preferred training methods were: practice under the direction of experienced CRCs (90.85%, 298 people), step-by-step teaching of practical skills (88.41%, 290 people), case analysis and discussion (87.20%, 286 people), process simulation (83.23%, 273 people), and lecture-based teaching (76.52%, 251 people). The preferred post-training assessment methods were: case analysis (76.52%, 251 people), operation simulation (74.09%, 243 people), process simulation (73.17%, 240 people), written examination (66.16%, 217 people), and interview (63.72%, 209 people).Conclusions:The current pediatric CRC training is not enough to meet actual work needs. It is urgent to develop and promote a CRC training system that can meet work needs, laying the foundation for the construction of pediatric clinical research ecology in China.

ObjectiveTo explore the biological foundation of colorectal adenoma in damp-heat accumulation syndrome and the possible anti-tumor mechanism of Shenbai Jiedu prescription. MethodEight patients with colorectal adenoma in damp-heat accumulation syndrome, 11 patients with non-damp-heat accumulation syndrome, and 10 patients with colorectal cancer recruited by Jiangsu Provincial Hospital of Traditional Chinese Medicine from February 2019 to December 2020 meeting the inclusion criteria were clinically obtained, and the tissue of the three groups of patients was subjected to transcriptome sequencing to screen for the differentially expressed genes between the syndrome and the diseases. The intersection of the differentially expressed genes between the syndrome and the disease was taken for further screening of the differentially expressed genes sequentially increasing or sequentially decreasing in patients with non-damp-heat accumulation syndrome, damp-heat accumulation syndrome, and colorectal cancer, and functional enrichment analysis and signaling pathway enrichment analysis were carried out. Real-time polymerase chain reaction (Real-time PCR) was used to detect the effect of Shenbai Jiedu prescription on the expression of the above key differential genes. ResultBy comparing the damp-heat accumulation syndrome and non-damp-heat accumulation syndrome, a total of 384 differentially expressed genes were screened, of which 203 were up-regulated genes, and 181 were down-regulated genes. By comparing the colorectal adenoma of colorectal cancer and damp-heat accumulation syndrome, a total of 2 965 differentially expressed genes were screened, of which 2 460 were up-regulated genes, and 505 were down-regulated genes. The intersection of differentially expressed genes of the two groups was taken, and a total of 58 differentially expressed genes with the same changes were screened. The gene ontology functions were mainly enriched in UDP-galactose: β-N-acetylglucosamine beta-1,3-galactosyltransferase activity, N-acetyllactosaminide beta-1,3-N-acetylglucosaminyltransferase activity, and poly-N-acetyllactosamine biosynthetic process. Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathways were mainly enriched in glycosphingolipid biosynthesis-globo and isoglobo series, glycosphingolipid biosynthesis-lacto and neolacto series, and IL-17 signaling pathway. Shenbai Jiedu prescription significantly inhibited the expression of key genes involved in the enrichment, such as FOSB and B3GALT5, in a dose-dependent manner (P<0.05). ConclusionGlycolipid metabolism may be the biological foundation of colorectal adenoma in damp-heat accumulation syndrome, and Shenbai Jiedu prescription may inhibit colorectal adenoma carcinogenesis by down-regulating the expression of FOSB and B3GALT5.

ObjectiveTo observe the effects of Shenbai Jiedu prescription on fecal metabolomics and intestinal flora diversity distribution in patients with colorectal adenoma and explore its potential targets. MethodA total of 21 patients diagnosed with colorectal adenoma were enrolled in this study. Following a four-week administration of Shenbai Jiedu prescription, their clinical symptoms were observed, and fecal samples of patients before and after treatment were collected. Untargeted metabolomics and metagenomic analysis based on liquid chromatography-mass spectrometry (LC-MS) were employed to investigate the possible metabolic pathway of Shenbai Jiedu prescription and its influence on the distribution of intestinal flora in patients. ResultThe total scores of traditional Chinese medicine (TCM) syndromes of patients after drug administration decreased significantly (P<0.01). The results of untargeted metabolomics showed that the distribution of metabolites exhibited aggregation before and after drug administration, and a total of 106 differential metabolites were screened out (P<0.05). The Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis revealed that arginine-proline metabolism, ferroptosis, glycine, and serine and threonine metabolism were significantly enriched metabolic pathways (P<0.05). Notably, L-4-hydroxyglutamate semialdehyde, glutathione, isopentenyl pyrophosphate, creatinine, 4-acetamido-2-aminobutanoic acid, and guanidoacetic acid were found to be involved in these aforementioned metabolic pathways. Furthermore, the association between these metabolites and different intestinal flora was analyzed, and the results showed that Shenbai Jiedu prescription could interfere with metabolic pathways such as amino acid and ferroptosis in patients with colorectal adenoma by regulating intestinal flora such as Lachnoclostridium, Eggerthella, and Dialister (P<0.05). ConclusionShenbai Jiedu prescription may improve the clinical symptoms of patients by increasing the abundance of intestinal beneficial bacteria, reducing the abundance of harmful bacteria, and regulating metabolic pathways such as amino acid and ferroptosis in patients with colorectal adenoma. This study may provide some research ideas and directions for Shenbai Jiedu prescription to interfere with colorectal adenoma recurrence and carcinogenesis.
