Acute liver injury poses a serious threat to the life safety of patients， and currently there is still a lack of satisfactory treatment options. As a cytoprotective transcription factor， nuclear factor erythroid 2-related factor 2 （Nrf2） has important potential in the treatment of acute liver injury. Nrf2 exerts a protective effect by inducing the expression of antioxidant enzymes， regulating iron and fatty acid metabolism， protecting mitochondrial function， and inhibiting inflammatory responses， and it can also enhance the antioxidant capacity of the liver and inhibit the progression of acute liver injury by activating antioxidant response element and promoting the expression of the antioxidant enzymes such as heme oxygenase-1， glutathione transferase， and glutamate-cysteine ligase catalytic subunit. Nrf2 can modulate acute liver injury caused by different etiologies. Natural compounds such as curcumin and synthetic compounds such as oltipraz can activate Nrf2 through different mechanisms， enhance the antioxidant capacity of the liver， and thus exert a protective effect against acute liver injury. However， there are still various challenges in Nrf2 in the treatment of acute liver injury， and its mechanism of action remains unclear， with most studies in the stage of experimental study. In the future， it is expected to deeply investigate the mechanism of action of the Nrf2 signaling pathway， optimize drug development strategies， improve the clinical application theories for agonists， and provide more effective and precise treatment regimens for patients with acute liver injury.

Objective To analyze the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in Shanxi Province from 2012 to 2024, and predict the incidence trend for 2025, and to provide a scientific basis for the formulation of prevention and control strategies. Methods Based on the surveillance data of HFMD in Shanxi Province from 2012 to 2024, the spatial and temporal distribution characteristics and time trends of the disease were analyzed. The ARIMA model was constructed and used to predict the incidence trend in 2025. Results From 2012 to 2024, a total of 254 028 HFMD cases were reported in Shanxi Province, with an average annual incidence rate of 54.17 per 100 000 population, a severe case rate of 0.56%, and a case fatality rate (CFR) of 12.60 per 100 000 population. Joinpoint regression analysis showed that the incidence rate, severe case rate, mortality rate, and case fatality rate all presented a downward trend. The epidemic exhibited obvious seasonal distribution characteristics, with the peak period from April to November, and two incidence peaks in June-July and October-November. The male-to-female incidence ratio was 1.41:1. Children aged 1-5 years accounted for 89.24% of the total cases, among which scattered children (58.48%) and nursery children (33.54%) were the high-risk groups. Linfen City (96.06 /100 000) and Taiyuan City (88.54 /100 000) had relatively high incidence rates. After 2017, the proportion of enterovirus A71 (EV-A71) decreased, while coxsackievirus A16 (Cox-A16) and other enteroviruses became the main epidemic strains. The ARIMA(1,0,1)(0,1,1)₁₂ model predicted that the incidence of HFMD in 2025 would remain at the level of 2023-2024, and the dual-peak characteristic would continue. Conclusion From 2012 to 2024, the overall HFMD epidemic in Shanxi Province generally shows a significant downward trend. The high-risk population includes scattered children and nursery children under 5 years old, with high-incidence areas concentrated in the central and southern regions, requiring focused attention. The seasonal ARIMA model can effectively fit the evolutionary trend of HFMD incidence in Shanxi Province and possesses short-term predictive capability.

OBJECTIVE To compare the efficacy and safety of vedolizumab （VDZ） versus infliximab （IFX） in biologic-naive（Bio-naive） patients with moderate-to-severe active ulcerative colitis （UC）， and to analyze the factors influencing efficacy. METHODS Clinical data were retrospectively collected from Bio-naive patients with moderate-to-severe active UC who received treatment in the Department of Gastroenterology at Shanxi Provincial People’s Hospital from June 2023 to June 2024. Based on the type of biologic agent administered， the patients were divided into the IFX group （41 cases） and the VDZ group （30 cases）. Patients in the two groups received IFX （5 mg/kg） or VDZ （300 mg） for induction and maintenance of remission therapy. The two groups were compared regarding modified Mayo score， serological indicators （hemoglobin， albumin， platelet count， erythrocyte sedimentation rate， C-reactive protein）， combined medication， efficacy-related indexes （clinical response rate/remission rate， and endoscopic response rate/remission rate）， and the occurrence of adverse drug reactions （ADR）. Based on Logistic regression model， univariate and multivariate analyses were conducted to identify potential factors influencing clinical remission at week 14 and endoscopic remission at week 38. RESULTS There were no statistically significant differences in clinical response rate/remission rate， or endoscopic response rate/remission rate between the two groups at weeks 14 and 38 （ P ＞0.05）. However， at week 14 of treatment， the proportion of patients using concomitant corticosteroids in VDZ group was 26.67%， significantly higher than the 7.50% in IFX group （ P ＜0.05）. There was no statistical significance in the overall incidence of ADR between the two groups （ P ＞0.05）； all ADRs in the IFX group were grade 3 and led to treatment discontinuation （6 cases）， whereas ADR in the VDZ group was grade 2 and did not interrupt therapy （1 case）. Univariate and multivariate regression analyses revealed that disease type （relapsing） was significantly associated with clinical remission at week 14 of treatment， and a history of smoking was significantly associated with endoscopic remission at week 38 of treatment （the odds ratios were 0.08 for both， with 95% confidence intervals of 0.01-0.77 and 0.01-0.91 respectively， P ＜0.05）. CONCLUSIONS For Bio-naive patients with moderate-to-severe active UC， VDZ and IFX demonstrate comparable efficacy in inducing and maintaining clinical remission and promoting mucosal healing， as well as overall safety. Although IFX can achieve faster control of inflammation in the early stage of the disease， it causes more severe ADR. Disease type （relapsing） and smoking history are identified as independent negative predictors for short-term clinical remission and long-term endoscopic remission， respectively.

Adipose tissue-derived mesenchymal stem cells (ADSCs) are crucially involved in various biological processes because of their self-renewal, multi-differentiation, and immunomodulatory activities. Some ADSC's characteristics have been associated with the basic theory of Chinese medicine (CM), especially the Meridian theory. CM can improve the biological properties of ADSCs to facilitate their use in injury treatment, restore immune homeostasis, and inhibit inflammatory responses. Therefore, the combination of CM and ADSCs may be a new promising research direction in integrative medicine of China. This review summarizes the association between CM and ADSCs to assess the potential application value of their combination against various diseases.

Inflammation represents a critical immune response triggered by cellular activities and inflammatory mediators following tissue damage. It plays a central role in the pathological progression of diverse diseases, including psychiatric disorders, cancer, and immunological conditions, rendering it an essential target for therapeutic intervention. Periodontitis, a prevalent oral inflammatory disease, is a leading cause of tooth loss and poses significant health challenges globally. Traditionally, inflammatory diseases such as periodontitis have been treated with systemic administration of synthetic chemicals. However, recent years have witnessed challenges, including drug resistance and microbial dysbiosis associated with these treatments. In contrast, natural products derived from Chinese medicine offer numerous benefits, such as high safety profiles, minimal side effects, innovative pharmacological mechanisms, ease of extraction, and multiple targets, rendering them viable alternatives to conventional antibiotics for treating inflammatory conditions. Numerous effective anti-inflammatory natural products have been identified in traditional Chinese medicine (TCM), including alkaloids, flavonoids, terpenoids, lignans, and other natural products that exhibit inhibitory effects on inflammation and are potential therapeutic agents. Several studies have confirmed the substantial anti-inflammatory and immunomodulatory properties of these compounds. This comprehensive review examines the literature on the anti-inflammatory effects of TCM-derived natural products from databases such as PubMed, Web of Science, and CNKI, focusing on terms like "inflammation", "periodontitis", "pharmacology", and "traditional Chinese medicine". The analysis systematically summarizes the molecular pharmacology, chemical composition, and biological activities of these compounds in inflammatory responses, alongside their mechanisms of action. This research seeks to deepen understanding of the mechanisms and biological activities of herbal extracts in managing inflammatory diseases, potentially leading to the development of promising new anti-inflammatory drug candidates. Future applications could extend to the treatment of various inflammatory conditions, including periodontitis.

Moringa oleifera, widely utilized in Ayurvedic medicine, is recognized for its leaves, seeds, and velamen possessing traditional effects such as vātahara(wind alleviation), sirovirecaka(brain clearing), and hridya(mental nourishment). This study aims to identify the medicinal part of ■ in the Sārasvata ghee formulation as described in the Bower Manuscript, while investigating the ameliorative effects of different medicinal parts of M. oleifera on learning and memory deficits in mice and elucidating the underlying molecular mechanisms. A total of 144 male ICR mice were randomly assigned to the following groups: control, model(scopolamine hydrobromide, Sco, 2 mg·kg~(-1)), donepezil(donepezil hydrochloride, Don, 3 mg·kg~(-1)), M. oleifera leaf low-, medium-, and high-dose groups(0.5, 1, 2 g·kg~(-1)), M. oleifera seeds low-, medium-, and high-dose groups(0.25, 0.5, 1 g·kg~(-1)), and M. oleifera velamen low-, medium-, and high-dose groups(0.31, 0.62, 1.24 g·kg~(-1)). Learning and memory abilities were assessed using the passive avoidance test and Morris water maze. Nissl and HE staining were employed to examine histopathological changes in the hippocampus. Transcriptomics and targeted metabolomics were used to screen differential genes and metabolites, with MetaboAnalyst 6.0 and O2PLS methods applied to identify key disease-related targets and pathways. RESULTS:: demonstrated that M. oleifera leaf(1 g·kg~(-1)) significantly ameliorated Sco-induced learning and memory deficits, outperforming M. oleifera seeds(0.25 g·kg~(-1)) and M. oleifera velamen(1.24 g·kg~(-1)). This was evidenced by improved behavioral performance, reversal of neuronal damage, and reduced acetylcholinesterase(AChE) activity. Multi-omics analysis revealed that M. oleifera leaf upregulated Tuba1c gene expression through the synaptic vesicle cycle, enhancing glutamate(Glu), dopamine(DA), and acetylcholine(ACh) release via Tuba1c-Glu associations for neuroprotection. M. oleifera seeds targeted the dopaminergic synapse pathway, promoting memory consolidation through Drd2-ACh associations. M. oleifera velamen was associated with the cocaine addiction pathway, modulating dopamine metabolism via Adora2a-DOPAC, with limited relevance to learning and memory. In conclusion, M. oleifera leaf exhibits superior efficacy and mechanistic advantages over M. oleifera seeds and velamen, suggesting that the ■ in the Sārasvata ghee formulation is likely M. oleifera leaf, providing scientific evidence for its identification in ancient texts.

Diabetic retinopathy is a common blinding complication in diabetic patients. Compared with conventional fundus color photography, fundus fluorescein angiography can dynamically display retinal vessel permeability changes, offering unique advantages in detecting early small lesions such as microaneurysms. However, existing intelligent diagnostic research on diabetic retinopathy images primarily focuses on fundus color photography, with relatively insufficient research on complex lesion recognition in fluorescein angiography images. This study proposed an adaptive multi-label classification model (D-LAM) to improve the recognition accuracy of small lesions by constructing a category-adaptive mapping module, a label-specific decoding module, and an innovative loss function. Experimental results on a self-built dataset demonstrated that the model achieved a mean average precision of 96.27%, a category F1-score of 91.21%, and an overall F1-score of 94.58%, with particularly outstanding performance in recognizing small lesions such as microaneurysms (AP = 1.00), significantly outperforming existing methods. The research provides reliable technical support for clinical diagnosis of diabetic retinopathy based on fluorescein angiography.

Objective: To explore the facilitating and hindering factors of mental health promotion activities in junior and senior high schools from teachers perspectives, as well as coping strategies, so as to provide evidence for implementing teacher led mental health promotion programs. Methods: From September 2023 to September 2024, by using purposive sampling method, 5 junior high schools, 5 regular high schools, 2 vocational high schools in four provinces and municipalities (Tianjin, Shanxi, Shandong, and Jiangxi) were selected. A total of 92 teachers (78 homeroom teachers and 14 full time or part time psychological counselors) were interviewed using semi structured focus group discussions (one session per school, totaling 12 sessions). Thematic analysis was applied to code and analyze the interview transcripts. Results: The implementation of mental health promotion activities in middle schools was influenced by three levels: teachers, schools and society. Specifically, teachers exhibited a high support low capability phenomenon (81 participants supported conducting such activities, but 71 felt lacking in professional capacity); activity effectiveness and support systems were imbalanced (42 mentioned significant effects, while 78 reported insufficient support); there was a mismatch between student demand and activity content (9 mentioned students had psychological needs, but 11 indicated existing activities failed to meet these needs); administrative support and sustainability showed disparities (14 believed sufficient administrative support existed, while 37 noted sustainability issues); parental awareness and participation remained inadequate (11 highlighted parents need for mental health knowledge, and 37 perceived insufficient understanding of psychological issues among parents). Effective strategies included enhancing teachers effectiveness, providing essential skill training, focusing on the needs of teenagers,enhancing program sustainability, and eliminating misconceptions about mental health among parents. Conclusion Mental health promotion activities in junior and senior high schools should focus on enhancing teachers skills, improving activity sustainability, reducing stigma among parents, and establishing a collaborative network for school based mental health promotion.

Objective:To analyze the molecular characteristics of prevalent Bordetella pertussis (Bp) isolates in Liaocheng City, Shandong Province in 2024. Methods:From March to August 2024, oropharyngeal swabs were collected from suspected pertussis cases at Liaocheng People′s Hospital in Shandong Province for Bp isolation. A total of 99 Bp isolates were obtained. Whole-genome sequencing was performed on all isolates, followed by Multilocus Sequence Typing (MLST), vaccine antigen-related gene typing (including ptxP, ptxA, ptxB, ptxC, ptxD, ptxE, fhaB, fim2, fim3, and prn), 23S rRNA gene typing, and phylogenetic analysis. To capture the differences between Bp isolates and vaccine strains in Liaocheng City, the international vaccine strain Tohama I and the Chinese vaccine strain CS were included in the analysis. Antimicrobial resistance testing against 11 agents was performed on 52 isolates. Results:The throat swabs of 99 Bp isolates were collected from patients aged 44 days to 42 years, and the median age of the patients was 7 (5, 8) years. All isolates ptxP were ptxP3 type. 74 isolates (74.75%) carried the prn150, while 21 isolates (21.21%) were prn-deficient. The predominant antigenic profile was ptxP3/ ptxA1/ ptxB1/ ptxC4/ ptxD1/ ptxE4/ fhaB1/ fim2-1/ fim3-1/ prn150, found in 72 isolates (72.73%). All 99 isolates carried the A2047G mutation in the 23S rRNA gene. Antimicrobial susceptibility testing showed that the MICs of macrolides and clindamycin for all 52 Bp isolates were all >256 mg/L. However, the isolates showed low MIC for seven other antimicrobials tested, including trimethoprim-sulfamethoxazole, amoxicillin, and levofloxacin. MLST typing revealed that 94 isolates (94.95%) were identified as ST-2, while 5 isolates (5.05%) belonged to a novel sequence type (ST-118). Phylogenetic analysis demonstrated that all 99 Bp isolates were highly homologous but clustered in evolutionary branches distinct from vaccine strains. Conclusion:In 2024, Bordetella pertussis isolates in Liaocheng City exhibit distinct clonal epidemic characteristics, with the predominant antigenic genotype being ptxP3/ ptxA1/ ptxB1/ ptxC4/ ptxD1/ ptxE4/ fhaB1/ fim2-1/ fim3-1/ prn150. All isolates are resistant to macrolide antibiotics.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.
