Objective To explore the differences of Th17 population and serum transforming growth factor (TGF)-β1 levels between early-and late-stage primary biliary cirrhosis (PBC) and their roles in pathogenesis.Methods Peripheral Th17 counts were analyzed by flow cytometry.The expression of IL-17A in peripheral blood mononuclear cells and TGF-β1 were measured by real-time quantitative polymerase chain reaction.Serum concentration of TGF-β1 was measured by enzyme-linked immunosorbent assay.Liver biopsies were stained with hematoxylin-eosin to determine the pathological stage.Results were evaluated using KrustalWallis test followed by Mann-Whitney U tests for comparisons of Th17 population between patients with early and late PBC,patients with chronic hepatitis B (CHB) and health controls (HCs).ANOVA followed by LSD t-tests were used for comparing IL-17 mRNA,TGF-β1 mRNA and TGF-β1 serum concentration between groups.The correlations between Mayo risk score and peripheral Th17 of PBC patients,Mayo risk score and serum concentration of TGF-β1 was analyzed by Pearson correlation analysis separately.Results The peripheral Th17 population increased in patients with early PBC (1.03±0.33)％,compared to those with late PBC [(0.48± 0.13％,U=14.0,P＜0.01],CHB [(0.56±0.35)％,U=104.5,P＜0.01],and HCs [(0.36±0.17)％,U=8.0,P＜0.01],while TGF-β1 changed in the opposite direction.Serum concentration of TGF-β1 elevated in late PBC (43.0± 18.7) ng/ml compared with early PBC (29.5±12.2) ng/ml,t=2.85,P=0.006.Conclusion The opposite changes of Th17 population and TGF-β1 level in early and late PBC indicated their different roles in different stages.Th17 may contribute to the autoimmune response in early PBC,participate in the occurrence of autoimmune inflammation,while TGF-β1 to fibrogenesis in late stage.In addition,the possible regulation mechanisms of differentiation of Th17 by TGF-β1 cannot be ignored.

Objective To observe the permeability and stability of the transfection of antisense oligonucleotide (ASODN) hybridized epidermal growth factor receptor (EGFR) to retinal glial cells (RG). Methods Phosphorothioate and unmodified EGFR ASODN conjugated with 5′ isothiocyanate (5′ FITC) were encapsulated with or without lipofectin, and then added into human retinal glial cells culture media. The cellular permeability and stability of the transfection were observed by fluorescence microscopy in fixed cells. Results In the absence of lipofectin, phosphorothioate and unmodified EGFR ASODN were found in a few RG cells at 30 minutes, and in about 50% RG cells at 4 hours. Phosphorothioate EGFR ASODN were kept in RG cells for 3 4 hours and disappeared at about 8 hours. In the presence of lipofectin, phosphorothioate and unmodified EGFR ASODN were found in a few RG cells at 15 minutes and about 70% 80% RG cells at 4 hours. Phosphorothioate EGFR ASODN were kept in cells for 10 12 hours, and phosphorothioate and unmodified EGFR ASODN were disappeared at about 14 hours and 4 hours respectively. Conclusion 5′ FITC EGFR ASODN encapsulated with lipofectin could enter RG cells and express stably in RG cells.

Objective: To map the research hotspots, developmental trends, and existing challenges in the integration of artificial intelligence (AI) with multi-omics in traditional Chinese medicine (TCM) through comprehensive bibliometric analysis. Methods: China National Knowledge Infrastructure (CNKI), Wanfang Data, China Science and Technology Journal Database (VIP), Chaoxing Journal Database, PubMed, and Web of Science were searched to collect literature on the theme of AI in TCM multi-omics research from the inception of each database to December 31, 2024. Eligible records were required to simultaneously address AI, TCM, and multi-omics. Quantitative and visual analyses of publication growth, core authorship networks, institutional collaboration patterns, and keyword co-occurrence were performed using Microsoft Excel 2021, NoteExpress v4.0.0, and Cite Space 6.3.R1. AI application modes in TCM multi-omics research were also categorized and summarized. Results: A total of 1 106 articles were enrolled (932 Chinese and 174 English). Publication output has increased continuously since 2010 and accelerated after 2016. Region-specific collaboration clusters were identified, dominated by Beijing University of Chinese Medicine, China Academy of Chinese Medical Sciences, Shanghai University of Traditional Chinese Medicine, and Nanjing University of Chinese Medicine. Keyword co-occurrence analysis revealed that current AI applications predominantly centered on metabolomics and algorithms such as cluster analysis and data mining. Research foci mainly ranked as follows: single herbs, herbal formulae, and disease-syndrome differentiation. Conclusion Machine learning methods are the predominant integrative modality of AI in the realm of TCM multi-omics research at present, utilized for processing omics data and uncovering latent patterns therein. The domain of TCM, in addition to investigating omics information procured through high-throughput technologies, also integrates data on traditional Chinese medicinal substances and clinical phenotypes, progressing towards joint analysis of multi-omics, high-dimensionality of data, and multi-modality of information. Deep learning approaches represent an emerging trend in the field.

Objective To explore the risk factors of Schistosoma japonicum infection in the residents in Xingzi County,Ji?angxi Province. Methods Six administrative villages from different areas were randomly selected by the cluster sampling meth?od as the study sites in Xingzi Country in 2013,and all the residents aged 5 years or above were investigated epidemiologically, and the schistosome infection was surveyed by Kato?Katz technique. The risk factors of schistosomiasis were analyzed by using the Chi?square test analysis and multivariate Logistic regression model. Results In 2013,there were 2 050 residents received the stool examination and 146 persons were positive,the schistosome infection rate was 7.1%. The Chi?square test showed that gender,age,occupation and education level were associated with the population infection rate(χ2=26.485、16.836、25.700、90.805,all P<0.05). The multivariate Logistic regression mode showed that the probability of schistosomiasis for the male was 3.041 times as much as that for the female;the probability of schistosomiasis for the illiteracy and primary education level crowd was 8.870 times as much as that for the college degree or above crowed;the probability of schistosomiasis for the junior middle school education level crowd was 5.598 times as much as that for the college degree or above crowed;the probability of schistoso?miasis for the high school education level crowd was 2.995 times as much as that for the college degree or above crowed;the probability of infection of fishermen was the highest,which was 3.053 times as much as that for the other professional crowds. Conclusions The risk factors of schistosome infection mainly include gender,occupation and the education level. We should strengthen the health education of schistosomiasis control,protection against the infested water contact,and so on.

Objective To assess the role of the different pancreatic islet β cell function index in the evaluation of glucose metabolism in different duration of type 2 diabetes mellitus (T2DM).Methods Normal glucose tolerance subjects without diabetes family history (NC group,48 cases) and T2DM patients (182 cases) were enrolled.The T2DM patients were divided into three groups:less than 5 years group (DM ＜5 group,74 cases),5-10 years group (DM5-10 group,51 cases) and more than 10 years group ( DM ＞10 group,57 cases).Oral glucose tolerance test (OGTT) and insulin release test were taken in all groups.Insulin resistance index (HOMA-IR) and whole body insulin sensitivity index [ISI(Matsuda)] were used to estimate insulin sensitivity,and early insulin secretion index ( △ I30/ △ G30) and glucose disposition index (DI) were used to evaluate the function of pancreatic islet β cell.Results HOMA-IR was increased and ISI (Matsuda) was decreased in DM ＜5 group,DM5-10 group and DM ＞10 group compared with those in NC group [HOMA-IR:8.78 ± 7.12,8.08 ± 3.67,7.84 ± 5.08 vs.4.76 ± 3.43;ISI(Matsuda):46.78 ± 29.00,36.71 ± 16.67,38.86 ±21.72 vs.61.13 ± 32.08,P ＜ 0.05],however,there was no significant difference among DM ＜5 group,DM5-10 group and DM ＞10 group.△ I30/ △ G30 and DI were decreased in DM ＜5 group,DM5-10 group and DM ＞10 group compared with those in NC group [ △ I30 △ G30:( 68.41 ± 361.52 ),(4.31 ± 3.42 ),(7.70 ± 5.78 ) mU/mmol vs.(92.65 ± 309.29) mU/mmol;DI:0.0421 ± 0.0123,0.0412 ± 0.0123,0.0363 ± 0.0116 vs.0.1151 ± 0.0236,P ＜ 0.05 ],and there was no significant difference in △ I30 / △ G30 among DM ＜5 group,DM5-10 group and DM ＞10 group,however,DI was decreased in DM＞10 group compared with that in DM＜5 group and DM5-10 group (P＜0.05).ConclusionsHOMA-IR,ISI (Matsuda),△I30/△G30 are not sensitive to evaluate the insulin resistance of different duration.DI can reflect the glucose utilization of pancreatic islet β cell earlier and the ability to regulate blood sugar steady state changes.
