BACKGROUND:Inflammation affects the osteogenic differentiation of periodontal ligament stem cells,and the osteogenic ability and autophagy level of periodontal ligament stem cells are closely related.However,there are no relevant reports on whether inflammation affects the osteogenic ability and autophagy level of periodontal ligament stem cells at different stages of osteogenic differentiation. OBJECTIVE:To explore alkaline phosphatase expression and autophagy periodontal ligament stem cells levels in periodontitis and normal conditions. METHODS:Periodontal ligament stem cells from normal and periodontitis patients were isolated and cultured,and underwent Vimentin,pan-CK,and Stro-1 fluorescence staining.At 3,7,and 14 days of osteogenic differentiation,western blot assay was used to detect the protein expression levels of alkaline phosphatase,LC3B,Beclin1,and ATG5 in normal and inflammatory periodontal ligament stem cells.The mRNA expression levels of alkaline phosphatase,bone sialoprotein,osteocalcin,Runx2,LC3B,Beclin1,and ATG5 were detected by real-time PCR. RESULTS AND CONCLUSION:(1)Stro-1 was positive,Vimentin was positive,and pan CK was negative in periodontal ligament stem cells.(2)At 3,7,and 14 days after osteogenic differentiation,compared with normal periodontal ligament stem cells,the mineralization nodules formed by periodontal ligament stem cells from inflammatory sources were significantly reduced(P<0.01);the expression of alkaline phosphatase protein and mRNA was significantly lower(P<0.05);the mRNA expression levels of bone sialoprotein,osteocalcin,and Runx2 were significantly decreased(P<0.05).(3)At 7 and 14 days after osteogenic differentiation,compared with normal periodontal ligament stem cells,the expression levels of ATG5,LC3B,and Beclin1 proteins and mRNA of periodontal ligament stem cells were downregulated(P<0.05).These findings suggest that inflammation reduces the activity of periodontal ligament stem cells in mineralizing nodule formation and the expression of alkaline phosphatase and weakens the autophagy potential of periodontal ligament stem cells at 7 and 14 days after osteogenic differentiation.

Objective To explore the clinical information of female patients with pulmonary nodules and the distribution of traditional Chinese medicine (TCM) syndromes and their elements. Methods A cross-sectional study was conducted to collect the basic information, medical history data, image data, and four diagnostic information of female patients with pulmonary nodules. The distribution characteristics of TCM syndromes and their elements in female patients with pulmonary nodules were determined by KMO test, Bartlett spherical test, systematic cluster analysis, chi-square test, and other methods. Results A total of 721 female patients with pulmonary nodules were included in this study. The patients were mainly 45-59 years old, had secondary school education or above, and had a history of oil smoke exposure as clinical characteristics. The pulmonary nodules were mainly 6-10 mm in size and appeared as multiple and ground glass nodules. The clinical symptoms were mainly fatigue, emotional irritability, and shortness of breath. The main syndromes of disease location were the spleen, liver, and lung; and the main syndromes of disease were phlegm, dampness, and qi deficiency. The main complex syndromes were spleen deficiency and dampness, liver stagnation, and qi/yin deficiency. Conclusion Middle age, high education, and multiple small ground glass nodules are the clinical characteristics of female patients with pulmonary nodules. Exposure to oil smoke is an important cause of the occurrence of female pulmonary nodules. During treatment, attention should be paid to strengthening the spleen, removing dampness, soothing the liver, regulating and tonifying qi, and nourishing yin.

ObjectiveTo evaluate the methodological and reporting quality of clinical practice guidelines for Chinese patent medicine (CPM) with internationally recognized tools the appraisal of guidelines for research and evaluation (AGEREE) Ⅱ and reporting items for practice guidelines in healthcare (RIGHT), thereby providing refe-rence for the clinical application and future development of CPM guidelines. MethodsDatabases including CNKI, VIP, Wanfang and Sinomed were searched for CPM guidelines, as well as medlive.cn, websites of China Association of Chinese Medicine and Chinese Medical Association, and reference lists of the included papers. The quality of the guidelines was evaluated using the AGREE Ⅱand RIGHT tools, and consistency tests were performed using Interclass Correlation Coefficient, and descriptive analysis and chi-square test were used to analyze the reporting rate for each domain and the average score for each item. ResultsFinally, 140 CPM guidelines were included, of which 51 were disease-oriented and 89 were drug-oriented, all of which were issued by China. For 51 disease-oriented CPM guidelines, the highest average score of all six AGREE Ⅱ domains was 73.32% for clarity, and the lowest was 26.80% for application; for 89 drug-oriented CPM guidelines, the highest average score was 55.62% for scope and purpose, and the lowest was 31.32% for rigour of development. In terms of the seven domains of the RIGHT checklist, the highest reporting rate was 68.26% for background, and lowest was 27.45% for other areas regarding the disease-oriented CPM guidelines; the highest reporting rate was 61.31% for background, and the lowest was 4.49% for other areas regarding drug-oriented CPM guidelines. The average reporting rate was higher for disease-oriented than drug-oriented CPM guidelines in three domains of AGREE Ⅱ (rigour of development, clarity of presentation, editorial independence), as well as four domains of RIGHT checklist (basic information, evidence, funding and declaration and management of interests, and other areas). ConclusionThe overall methodology and reporting quality of the current CPM guidelines still need to be improved. It is recommended that future guideline development teams should strictly refer to the AGREE Ⅱ and RIGHT checklist, and take into account of the characteristics of CPM guidelines and relevant methodo-logical suggestions in the development and reporting of CPM guidelines, thereby guiding the clinical use of CPM in a better way.

Objective:
To explore and validate the potential targets of Paeoniae Radix Alba (P. Radix, Bai Shao) in protecting against chemical liver injury through network pharmacology, molecular docking technology, and in vitro cell experiments.
Methods:
Network pharmacology was used to identify the common potential targets of P. Radix and chemical liver injury. Molecular docking was used to fit the components, which were subsequently verified in vitro. A cell model of hepatic fibrosis was established by activating hepatic stellate cell (HSC)-LX2 cells with 10 ng/mL transforming growth factor-β1. The cells were exposed to different concentrations of total glucosides of paeony (TGP), the active substance of P. Radix, and then evaluated using the cell counting kit-8 assay, enzyme-linked immunosorbent assay, and western blot.
Results:
Analysis through network pharmacology revealed 13 key compounds of P. Radix, and the potential targets for preventing chemical liver injury were IL-6, AKT serine/threonine kinase 1, jun proto-oncogene, heat shock protein 90 alpha family class A member 1 (HSP90AA1), peroxisome proliferator activated receptor gamma (PPARG), PTGS2, and CASP3. Gene Ontology (GO) enrichment analysis indicated the involvement of response to drugs, membrane rafts, and peptide binding. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that the main pathways involved lipid and atherosclerosis and chemical carcinogenesis-receptor activation. Paeoniflorin and albiflorin exhibited strong affinity for HSP90AA1, PTGS2, PPARG, and CASP3. Different concentrations of TGP can inhibit the expression of COL-Ⅰ, COL-Ⅲ, IL-6, TNF-α, IL-1β, HSP-90α, and PTGS2 while increasing the expression of PPAR-γ and CASP3 in activated HSC-LX2 cells.
Conclusion
P. Radix primarily can regulate targets such as HSP90AA1, PTGS2, PPARG, CASP3. TGP, the main active compound of P. Radix, protects against chemical liver injury by reducing the inflammatory response, activating apoptotic proteins, and promoting the apoptosis of activated HSCs.

BackgroundPatients with schizophrenia and depressive disorders exhibit abnormalities in perceptual processing. Previous perceptual studies are mainly based on asking participants to fill in a questionnaire, and little research has been undertaken on objective behavior in patients with schizophrenia and depressive disorders. ObjectiveTo explore the behavioral changes in vibrotactile sense among patients with schizophrenia and depressive disorders, so as to enrich relevant findings in objective behavioral research. MethodsFrom March 2021 to September 2023, 33 patients with schizophrenia and 31 patients with depressive disorders in the outpatient and inpatient departments of Beijing Huilongguan Hospital and met the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnostic criteria were enrolled. And another 34 healthy controls were concurrently recruited at Beihang University and Beijing Huilongguan Hospital. Patients with schizophrenia were assessed using Positive and Negative Symptom Scale (PANSS), and patients with depressive disorders were assessed using Hamilton Depression Scale-17 item (HAMD-17). The vibrotactile sensitivity of the left hand in all participants was tested in a delay match-to-sample procedure, and the correct rate of vibrotactile delayed discrimination task was compared among the three groups. ResultsCompared with healthy controls, a reduction was found in the correct rates at index finger, middle finger and ring finger in patients with schizophrenia (P<0.01), the average correct rate at five fingers in patients with schizophrenia (P=0.001), and the correct rate at thumb in patients with depressive disorders (P=0.026). No statistical difference was reported in correct rate of vibrotactile delayed discrimination task between patients with depression disorders and schizophrenia (P>0.05). The average correct rate of vibrotactile sense in schizophrenia group was not significantly correlated with the duration of disease, age of onset, chlorpromazine equivalent doses and PANSS score (r=0.058、0.045、0.114、-0.194, P>0.05). The average correct rate in depressive group was negatively correlated with age of onset (r=-0.415, P=0.020), but not significantly correlated with the duration of disease and HAMD-17 score (r=-0.044, 0.142, P>0.05). ConclusionPatients with schizophrenia and depressive disorders have impaired vibrotactile sense. The vibrotactile sense is impaired in index, middle and ring fingers among patients with schizophrenia, and in thumbs of patients with depressive disorders. Moreover, the impairment in patients with depressive disorders may be related to the age of onset. [Funded by 2023 Hebei Provincial Graduate Innovation Funding Project (number, CXZZSS2023140)]

ObjectiveTo investigate the therapeutic effect of Baihe Wuyaotang (BWT) on non-alcoholic fatty liver disease (NAFLD) and elucidate its underlying mechanism. MethodC57BL/6J mice were randomly assigned to six groups: normal control, model, positive drug (pioglitazone hydrochloride 1.95×10-3 g·kg-1), and low-, medium-, and high-dose BWT (1.3,2.5 and 5.1 g·kg-1). Following a 12-week high-fat diet (HFD) inducement, the mice underwent six weeks of therapeutic intervention with twice-daily drug administration. Body weight was monitored weekly throughout the treatment period. At the fifth week, glucose tolerance (GTT) and insulin tolerance (ITT) tests were conducted. Subsequently, the mice were euthanized for the collection of liver tissue and serum, and the subcutaneous adipose tissue (iWAT) and epididymal adipose tissue (eWAT) were weighed. Serum levels of total triglycerides (TG) and liver function indicators,such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), were determined. Histological examinations, including oil red O staining, hematoxylin-eosin (HE) staining, Masson staining, and transmission electron microscopy, were performed to evaluate hepatic lipid deposition, pathological morphology, and ultrastructural changes, respectively. Meanwhile, Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were employed to analyze alterations, at both gene and protein levels, the insulin signaling pathway molecules, including insulin receptor substrate 1/2/protein kinase B/forkhead box gene O1 (IRS1/2/Akt/FoxO1), glycogen synthesis enzymes phosphoenolpyruvate carboxy kinase (Pepck) and glucose-6-phosphatase (G6Pase), lipid metabolism-related genes stearoyl-coA desaturase-1 (SCD-1) and carnitine palmitoyltransferase-1 (CPT-1), fibrosis-associated molecules α-smooth muscle actin (α-SMA), type Ⅰ collagen (CollagenⅠ), and the fibrosis canonical signaling pathway transforming growth factor-β1/drosophila mothers against decapentaplegic protein2/3(TGF-β1/p-Smad/Smad2/3), inflammatory factors such as interleukin(IL)-6, IL-8, IL-11, and IL-1β, autophagy markers LC3B Ⅱ/Ⅰ and p62/SQSTM1, and the expression of mammalian target of rapamycin (mTOR). ResultCompared with the model group, BWT reduced the body weight and liver weight of NAFLD mice(P<0.05, P<0.01), inhibited liver lipid accumulation, and reduced the weight of white fat: it reduced the weight of eWAT and iWAT(P<0.05, P<0.01) as well as the serum TG content(P<0.05, P<0.01). BWT improved the liver function as reflected by the reduced ALT and AST content(P<0.05, P<0.01). It improved liver insulin resistance by upregulating IRS2, p-Akt/Akt, p-FoxO1/FoxO1 expressions(P<0.05). Besides, it improved glucose and lipid metabolism disorders: it reduced fasting blood glucose and postprandial blood glucose(P<0.05, P<0.01), improved GTT and ITT(P<0.05, P<0.01), reduced the expression of Pepck, G6Pase, and SCD-1(P<0.01), and increased the expression of CPT-1(P<0.01). The expressions of α-SMA, Collagen1, and TGF-β1 proteins were down-regulated(P<0.05, P<0.01), while the expression of p-Smad/Smad2/3 was downregulated(P<0.05), suggesting BWT reduced liver fibrosis. BWT inhibited inflammation-related factors as it reduced the gene expression of IL-6, IL-8, IL-11 and IL-1β(P<0.01) and it enhanced autophagy by upregulating LC3B Ⅱ/Ⅰ expression(P<0.05)while downregulating the expression of p62/SQSTM1 and mTOR(P<0.05). ConclusionBWT ameliorates NAFLD by multifaceted improvements, including improving IR and glucose and lipid metabolism, anti-inflammation, anti-fibrosis, and enhancing autophagy. In particular, BWT may enhance liver autophagy by inhibiting the mTOR-mediated signaling pathway.

ObjectiveTo investigate the possible mechanism of modified Gegen Qinlian Decoction (葛根芩连汤) in treatment of ulcerative colitis (UC) from the view of intestinal mucosal epithelial barrier damage and epithelial mesenchymal transition. MethodsSixty male C57BL/6J mice were divided into blank group, model group, western medicine control group, and low-, medium-, and high-dose modified Gegen Qinlian Decoction groups, with 10 mice in each group. Except for the blank group, 3% dextran sodium sulfate (DSS) was used to induce colitis model by free drinking for 7 days, and on the first day of modelling, 6, 12, and 24 g/(kg·d) of modified Gegen Qinlian Decoction were given to the low-, medium-, and high-dose groups respectively, 5-aminosalicylic acid (5-ASA) 100 mg/(kg·d) given by gavage to western medicine control group, and 10 ml/kg distilled water were given to blank and model group by gavage, once a day for 7 days. Body mass of mice was recorded and disease activity index (DAI) scores were performed daily. The mice were anesthetized after 24h of the last administration and the colon was taken to observe the length of colon, HE staining was applied to observe the damage of colonic mucosa and score pathological states, Masson staining to detect the deposition of colonic collagen fibers, immunofluorescence to observe the distribution of F-actin in colonic mucosal epithelium, and immunohistochemistry to detect the expression of tight junction protein ZO-1, Occludin, E-cadherin and Vimentin. ResultsCompared with the blank group at the same time, the percentage of body mass of mice in the model group on day 7 of modelling significantly reduced and the DAI score was significantly increased (P<0.01); compared with the model group at the same time, the body mass of mice in the western medicine control group and all of modified Gegen Qinlian Decoction groups decreased, and the DAI scores of mice in the western medicine control group and the high-dose modified Gegen Qinlian Decoction group decreased (P<0.05 or P<0.01); compared with the same time of mice in the low-dos Gegen Qinlian Decoction group, the body mass of mice in the high-dose Gegen Qinlian Decoction group and the western medicine control group significantly elevated (P<0.05). Compared with the blank group, the length of the colon of mice in the model group was significantly shortened, the pathological score and the percentage of collagen area were significantly increased, the average fluorescence intensity of F-actin was reduced, the protein levels of ZO-1, Occludin and E-cadherin in the colon tissue decreased, and the protein level of Vimentin elevated (P<0.01). Compared with the model group, the length of colon significantly increased, patholo-gical score, collagen area percentage decreased, ZO-1, Occludin, E-cadherin protein levels increased and Vimentin levels decreased in all medicated groups; the average fluorescence intensity of F-actin increased in the western medicine control group and the middle- and high-dose Gegen Qinlian Decoction groups (P<0.05 or P<0.01). Compared with the low-dose Gegen Qinlian Decoction group, the proportion of collagen fibre area in the middle-dose Gegen Qinlian Decoction group and the western medicine control group reduced; the mean fluorescence intensity of F-actin increased in the middle-dose Gegen Qinlian Decoction group; the protein levels of ZO-1 and E-cadherin increased in the western medicine control group, and the protein levels of ZO-1 increased in the high-dose Gegen Qinlian Decoction group (P<0.05). Compared with the medium-dose Gegen Qinlian Decoction group, the protein levels of ZO-1 elevated in the high-dose Gegen Qinlian Decoction group (P<0.05). Comapred with the high-dose Gegen Qinlian Decoction group, level of E-cadherin and Vimentin protein of the western medicine control group increased (P<0.05). ConclusionModified Gegen Qinlian Decoction was able to reduce colonic inflammation and mucosal barrier damage and inhibit the process of epithelial mesenchymal transition in mice models of ulcerative colitis, which may be one of its action mechanisms .

To investigate the differences in methylation levels of cuproptosis related genes in cervical cancer and their effects on clinical prognosis.Methods:The methylation data of 310 cervical tissue specimens were acquired from public databases. The UALCAN database was used to analyze the methylation level differences of 12 cuproptosis-related genes and study their level in different stages or grades of cervical cancer. Genes with statistically significant differences were selected for prognosis analysis using the EWAS datahub. Finally, gene-enrichment analysis, pathway analysis, immune infiltration analysis, the mutation rate and tumor mutation burden (TMB) of the genes in cervical cancer were analyzed using the cBioportal database. Two independent samples rank-sum test was used for differences in methylation levels and immune cell infiltration; comparative analyses of overall survival were performed using KM survival curves and Log-rank two-sided tests. TMB analyses were performed using the Wilcoxon Test for statistical analyses; Pearson correlation analysis was used for assessment in GSEA and pathway analyses.Results:The methylationβvalue of Cyclin Dependent Kinase Inhibitor 2A (CDKN2A gene) in the cervical cancer tissues of patients was 0.075 which was significantly higher than the methylationβvalue of 0.049 in normal human tissues ( P=0.008). Dihydrolipoamide S-Acetyltransferase (DLAT gene) methylation with a β value of 0.102 was significantly higher than normal human tissue methylation with a β value of 0.08 ( P=0.002), and the methylation level β value of Lipoyltransferase 1 (LIPT1 gene) in cervical cancer tissues was 0.06,which was significantly lower than normal human tissue methylation value of 0.092 ( P=0.009). Patients with CDKN2A gene methylation levels≥0.199 had an overall survival of 14.75 years, which was lower than that of patients with methylation levels<0.199 (17.56 years) ( P=0.034).The results of gene enrichment analysis indicated that it mainly involves biological processes such as the response to type I interferon and DNA replication. The expression of CDKN2A gene is positively correlated with the number of neutrophils and dendritic cells in the tumor microenvironment( P<0.05), and negatively correlated with the number ofmacrophages( P<0.05). TMB was higher in the group of variants of the CDKN2A gene than in the group of non-variants ( P=0.019). Conclusion:CDKN2A methylation is a potential biomarker for predicting the prognosis of cervical cancer.
