Objective: To explore the relationship between positive parenting styles and academic emotions in junior high school students, as well as the chain mediation effects of parent-child communication and peer relationships, providing a theoretical basis for family education interventions. Methods: Using stratified cluster random sampling, 1 063 students from four junior high schools in a city in Anhui Province were selected for questionnaire surveys, form March to April, 2025. Core variables were measured using the Short form Parenting Style Scale, Adolescent Parent-Child Communication Scale, Peer Relationship Scale, and Adolescent Academic Emotion Questionnaire. Group comparison was conducted using t-test or analysis of variance, and Pearson correlation analysis was used to examine the correlation between positive parenting styles, peer relationships, parent-child communication and positive academic emotions. Multiple linear regression analysis was used to examine the effects of positive parenting styles, peer relationships and parent-child communication on positive academic emotions. A mediation effect model and Bootstrap method were employed to test the chain mediation effects. Results: Students who were class leaders, had parents with higher education levels, or came from intact families scored significantly higher on positive academic emotions ( t/F =7.23, 13.73, 10.67, 4.45, all P < 0.01 ). Positive parenting styles, peer relationships, and parent-child communication were all positively correlated with positive academic emotions ( r =0.45, 0.41, 0.38), and all three positively predicted positive academic emotions ( β =0.24, 0.23, 0.12) (all P < 0.01 ). Further analysis showed that positive parenting styles directly predicted positive academic emotions ( β =0.40) and also indirectly influenced academic emotions through parent-child communication ( β =0.07), peer relationships ( β =0.05), and the chain mediation path of "parent-child communication → peer relationships" ( β =0.04) (all P <0.05), with the total indirect effect accounting for 40.55%. Conclusion Positive parenting styles enhance junior high school students academic emotions through the chain mediation path of "parent-child communication → peer relationships", providing theoretical support for interventions within the educational ecosystem.

OBJECTIVE To investigate the role and mechanism of paeonol in inhibiting the migration of bladder cancer T24 cells by regulating nuclear factor κB （NF-κB）/hypoxia-inducible factor-1α （HIF-1α）-mediated aerobic glycolysis. METHODS T24 cells were divided into control group， cisplatin group （positive control， 3.001 μg/mL）， and paeonol low-， medium- and high-dose groups （100， 200， 400 μg/mL）， respectively. After 24 h of administration intervention， the effect of paeonol on the migration ability of T24 cells was detected （expressed by the cell scratch wound healing rate）. The effect of paeonol on the mitochondrial membrane potential of T24 cells was detected （expressed by the ratio of red/green fluorescence intensity）. Cellular adenosine triphosphate （ATP） levels and lactate content in T24 cells were measured. The levels of NF-κB/HIF-1α signaling pathway， the expression of migration-related proteins， and key enzymes involved in aerobic glycolysis in the cells were all determined. RESULTS Compared with the control group， the cell scratch wound healing rates in the paeonol medium- and high-dose groups and the cisplatin group were decreased significantly （P＜0.01）； in the paeonol groups， the expression levels of NF-κB/HIF-1α signaling pathway-related proteins such as NF- κB and HIF-1α， migration-related proteins such as matrix metalloproteinase 2 （MMP2）， MMP9， and vascular endothelial growth factor， as well as key enzymes involved in aerobic glycolysis such as glucose transporter 1， hexokinase 2 and pyruvate kinase isozyme type M2， were all reduced to varying degrees in the cells， most of these reductions showed statistically significant differences （P＜0.05 or P＜0.01）； the ratio of red/green fluorescence intensity in mitochondria of cells in the medium- and high-dose paeonol groups were significantly decreased （P＜0.01）； the ATP concentration in cells of the paeonol high-dose group， and the lactate content in cells across all paeonol groups were significantly decreased （P＜0.05 or P＜0.01）. CONCLUSIONS Paeonol significantly inhibits the migration of bladder cancer T24 cells， and its mechanism of action may be related to the inhibition of the NF-κB/HIF-1α signaling pathway， and the down-regulation of key enzyme activities involved in aerobic glycolysis.

Objective To explore the correlation of MET status in patients with advanced prostatic acinar adenocarcinoma with the clinical pathological parameters and prognosis. Methods The specimen from 135 patients with advanced prostatic acinar adenocarcinoma was included. The expression of c-MET protein was detected via immunohistochemistry, and MET gene amplification was assessed by fluorescence in situ hybridization. The relationships of c-MET expression and gene amplification with clinicopathological features and prognosis were analyzed. Results The positive expression rate of c-MET was 52.60% (71/135). Compared with the c-MET expression in adjacent tissues, that in tumor tissues showed lower heterogeneous expression. Among the cases, 1.71% (2/117) exhibited MET gene polyploidy, but no gene amplification was detected. Positive c-MET expression was significantly correlated with high Gleason scores and grade groups (P=0.0073). However, no significant relationship was found between c-MET expression and progression-free survival or post-treatment t-PSA levels. Conclusion c-MET protein is expressed at a relatively low level in advanced prostatic acinar adenocarcinoma, suggesting that c-MET may not be a viable target for ADC drug development in prostatic acinar adenocarcinoma.

BACKGROUND: Alpha-glucosidase inhibitors or dipeptidyl peptidase-4 inhibitors are both hypoglycemia agents that specifically impact on postprandial hyperglycemia. We compared the effects of acarbose and sitagliptin add on to metformin on time in range (TIR) and glycemic variability (GV) in Chinese patients with type 2 diabetes mellitus through continuous glucose monitoring (CGM). METHODS: This study was a randomized, open-label, active-con-trolled, parallel-group trial conducted at 15 centers in China from January 2020 to August 2022. We recruited patients with type 2 diabetes aged 18-65 years with body mass index (BMI) within 19-40 kg/m 2 and hemoglobin A1c (HbA1c) between 6.5% and 9.0%. Eligible patients were randomized to receive either metformin combined with acarbose 100 mg three times daily or metformin combined with sitagliptin 100 mg once daily for 28 days. After the first 14-day treatment period, patients wore CGM and entered another 14-day treatment period. The primary outcome was the level of TIR after treatment between groups. We also performed time series decomposition, dimensionality reduction, and clustering using the CGM data. RESULTS: A total of 701 participants received either acarbose or sitagliptin treatment in combination with metformin. There was no statistically significant difference in TIR between the two groups. Time below range (TBR) and coefficient of variation (CV) levels in acarbose users were significantly lower than those in sitagliptin users. Median (25th percentile, 75th percentile) of TBR below target level <3.9 mmol/L (TBR 3.9 ): Acarbose: 0.45% (0, 2.13%) vs . Sitagliptin: 0.78% (0, 3.12%), P = 0.042; Median (25th percentile, 75th percentile) of TBR below target level <3.0 mmol/L (TBR 3.0 ): Acarbose: 0 (0, 0.22%) vs . Sitagliptin: 0 (0, 0.63%), P = 0.033; CV: Acarbose: 22.44 ± 5.08% vs . Sitagliptin: 23.96 ± 5.19%, P <0.001. By using time series analysis and clustering, we distinguished three groups of patients with representative metabolism characteristics, especially in GV (group with small wave, moderate wave and big wave). No significant difference was found in the complexity of glucose time series index (CGI) between acarbose users and sitagliptin users. By using time series analysis and clustering, we distinguished three groups of patients with representative metabolism characteristics, especially in GV. CONCLUSIONS: Acarbose had slight advantages over sitagliptin in improving GV and reducing the risk of hypoglycemia. Time series analysis of CGM data may predict GV and the risk of hypoglycemia.

Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

The pain-evoked potential electroencephalogram (EEG) is an effective electrophysiological indicator for pain assessment, yet its extraction is challenging due to interference from background activity and involuntary blinks. Although existing blink artifact-removal methods show efficacy, they face limitations such as the need for reference signals, neglect of individual differences, and reliance on user input, hindering their practical application in clinical pain assessments. In this paper, we propose a novel framework applying adaptive quadrature mirror filter banks (AQMFB) with discrete wavelet transform (DWT) to remove blink artifacts in pain EEG. Unlike traditional DWT methods that apply fixed wavelets across subjects, our method adapts wavelet construction based on the characteristics of EEG. Experimental results demonstrate that AQMFB-DWT outperforms four leading methods in removing blink artifacts with minimal distortion of pain information, all within an acceptable processing time. This technique is a valuable preprocessing step for enhancing the extraction of pain-evoked potentials.

Objective:To summarize the medication law and academic experience of Professor Yuan Jinsheng in the treatment of angina pectoris (AP) of coronary heart disease (CHD) through R language data mining technique.Methods:The effective outpatient medical records of Professor Yuan Jinsheng in the treatment of AP of CHD from January 1, 2016 to September 30, 2023 were selected, and the R 4.2.3 was used for frequency statistics, association rule analysis, systematic clustering analysis and correlation analysis of prescription drugs.Results:A total of 292 prescriptions were included, including 268 patients, involving 204 kinds of Chinese materia medica, and the total frequency of Chinese materia medica was 4 253 times. The main properties were warm and neutral, the main tastes were bitter, pungent and sweet, and the main meridians were spleen, lung and liver meridians. The analysis of association rules obtained 125 core TCM combinations, and the commonly used drug pair was Trichosanthis Fructus-Aurantii Fructus Immaturus. The core prescription composed of Aurantii Fructus Immaturus, Chuanxiong Rhizoma, Trichosanthis Fructus, Citri Reticulatae Pericarpium and Salviea Miltiorrhizae Radix et Rhizoma. Seven TCM groups of were obtained by systematic clustering analysis. Correlation analysis showed that the drug pairs with phi coefficient greater than 0.6 were in 8 groups.Conclusions:Studies suggest that AP of CHD is located in the heart, which is related to lung, spleen, liver and kidney, deficiency in root and excess in superficiality, phlegm, blood stasis and qi stagnation are important pathological factors. The treatment is based on the basic principles of tonifying qi, promoting yang, relieving rheumatism, resolving phlegm, activating blood circulation, and promoting qi circulation. It embodies Professor Yuan's academic thoughts and principles of differentiation and treatments of "taking fluency as the main point, regulating the five internal organs and weighing the root and superficiality".

Objective:To explore the current situation of professional identity of intern nursing students in Shandong Province, to analyze the potential characteristics of different categories of intern nursing students' professional identity, and to provide reference for formulating relevant intervention programs.Methods:From September to October 2023, using convenient cluster sampling, selected nursing students from different regions of Shandong Province colleges and universities as the research objects, a total of 1298 questionnaires were released and recovered, with 1221 valid questionnaires, and the effective recovery rate of questionnaires was 94.07%. General demographic data was collected, and information on nursing students' professional identity was investigated with the Nursing Students' Professional Identity Questionnaire, the Work Readiness Scale, and the Feedback Seeking Behavior Scale. Latent potential profiles of nursing students' sense of professional identity were analyzed by Mplus 8.3 software, and the best-fitting model was selected by the test of fitness and difference. The χ 2 test was used for comparison between groups of count data, analysis of variance (ANOVA) was used for comparison between groups of measure data, and the effects of each factor on different potential profiles were analyzed by multivariate logistic analysis. Results:A total of 1221 intern nursing students were 984 (80.6%) females and 237 (19.4%) males, aged (21.12±2.96) years old, with a total score of (64.23±14.99) for nursing students' professional identity. Nursing students' professional identity was divided into 3 categories: 98 (8.0%) in the low identity group, 624 (51.4%) in the medium identity group, and 496 (40.6%) in the high identity group. The gender, region, age, work readiness scores and feedback seeking behavior scores of nursing students in different categories were different, and the differences were statistically significant ( P<0.05). Compared with the high identity group, the nursing students in the low identity group were more likely to be included in the high identity group ( OR=0.390, 0.167, P=0.005, 0.006) with higher work readiness and better feedback seeking behavior. Compared with the high identity group, the higher work readiness and non-Jinan areas of the medium identity group were more likely to be included in the high identity group ( OR=0.597, 1.470, P=0.011, 0.012). Compared with the medium identity group, the more feedback seeking behaviors of the low identity group were more likely to be included in the medium identity group ( OR=10.411, P<0.001) . Conclusion:The level of professional identity of intern nursing students can be classified into 3 categories, and nursing administrators can improve work readiness and increase feedback seeking behaviors according to the potential characteristics of the different types to enhance the professional identity of nursing students.

Ferroptosis is closely associated with the progression of various diseases.There are a series of anti-ferroptosis systems in the cell,the main function of which is to eliminate lipid peroxides and inhibit the occurrence of ferropto-sis.Ubiquitination is a crucial type of post-translational protein modification which can influence the degradation,intracellular localization,or function of substrate proteins.Ubiquitination modification plays an important role in regulating key proteins in-volved in ferroptosis pathways,such as SLC7A11,GPX4,FSP1,iron metabolism-related proteins,and other critical proteins in ferroptosis pathways.This review aims to summarize the research progress on ubiquitination modification of these key proteins in ferroptosis pathways,thereby elucidating the specific role of ubiquitination in ferroptosis pathways.

ObjectiveTo clone the gene of Marmota himalayana type ‍Ⅰ interferon receptor β subunit （mhIFNAR2）， and to perform antibody preparation and functional identification. MethodsRT-PCR was used for amplification in the spleen tissue of Marmota himalayana to obtain the sequence， which was cloned to the prokaryotic expression vector pRSET-B to express the recombinant protein. Electrophoresis and Western blot were used for identification. BALB/c mice were immunized with the recombinant protein to prepare the polyclonal antibody of its extracellular domain； immunohistochemistry， immunofluorescence assay， and Western Blot were used for identification， and the method of siRNA blockade was used to investigate its function. An analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for comparison between two groups. ResultsA fragment of mhIFNAR2 （149‍ ‍—‍ ‍1 ‍300 bp） was obtained from spleen tissue， which showed the highest homology of 98.05% in marmot. A prokaryotic expression plasmid was successfully constructed for expression of the extracellular domain of the mhIFNAR2_{（50-181aa）} and was named pRSET-B.mhIFNAR2， and the recombinant protein expressed by this plasmid had a molecular weight of 27 kD， a purity of about 95% after purification， and a concentration of 160 μg/mL. After BALB/c mice were immunized with the purified recombinant protein， 1∶1 000 specific polyclonal antibodies were obtained， and immunohistochemistry and immunofluorescence assay showed the expression in cell membrane and cytoplasm. Among the three siRNAs synthesized， the siRNA starting from the 277 locus （siRNA277） could silence the expression of target genes and weaken the interferon signaling pathway compared with the blank control group and the negative control group （both P<0.05）. ConclusionThe fragment of mhIFNAR2 is obtained， and the polyclonal antibody for the extracellular domain of mhIFNAR2 is successfully prepared， with relatively high titer and specificity， and can be used for immunohistochemistry， immunofluorescence assay， and Western blot.
