In recent years, traditional Chinese medicine (TCM) has achieved significant progress in the treatment of inflammatory bowel disease (IBD). A comprehensive literature search was conducted covering the period from January 1, 2010, to December 30, 2024, across Chinese databases including China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP China Science and Technology Journal Database, and the Chinese Biomedical Literature Service System, as well as international databases such as PubMed, Web of Science, and Embase. The clinical applications and mechanistic studies of TCM in IBD were systematically reviewed. The current status of TCM research on the etiology and pathogenesis of IBD, innovative clinical practices, and multimodal therapeutic approaches, including Chinese herbal formulas, single herbs or active compounds, acupuncture, herbal retention enema, and acupoint application, were summarized, together with their synergistic effects when combined with western medical treatments. The development and application of Chinese patent medicines for IBD are undergoing a profound transition from efficacy validation to mechanistic exploration. Mechanistic studies on the effects of TCM in IBD mainly focus on regulating gut microbiota homeostasis, repairing the intestinal mucosal barrier, and modulating intestinal immune balance. Furthermore, future research directions for TCM-based IBD management are proposed, including the establishment of TCM diagnostic and treatment models, expanding integrated applications of external and internal TCM therapies, innovating personalized treatment strategies, and advancing drug development. These efforts aim to provide insights for the standardized and precision-oriented development of TCM in the diagnosis and treatment of IBD.

Objective To investigate the microbial disinfection and sterilization effectiveness of an electron linear accelerator on the surface and interior of postal packages, and to design and conduct a penetrating radiation disinfection and sterilization experiment. Methods This experiment selected Bacillus pumilus E601 (ATCC 27142) as the indicator microbial strain for radiation. An experimental model of postal package was subjected to penetrating radiation with different dose gradients using high-energy electron beams generated by an S-band 10 MeV electron linear accelerator. The disinfection and sterilization effectiveness was assessed by culturing and counting B. pumilus after high-energy electron beam radiation treatment. A control group was established to analyze the influence of actual absorbed doses at different gradients on the disinfection and sterilization effectiveness of the electron linear accelerator. Results The actual absorbed doses of high-energy electron-beam radiation required to achieve 1-, 3-, and 6-log reductions of B. pumilus were 1.63, 5.07, and 10.22 kGy, respectively. Complete inactivation was achieved at an absorbed dose of 10.92 kGy, which met the processing requirements specified in the technical standard for ionizing-radiation disinfection. Conclusion The experimental data indicated that the actual absorbed dose for B. pumilus is linearly positively correlated with the log reduction of bacterial colonies killed by electron beam radiation. For disinfection and sterilization requirements in different scenarios, the required actual absorbed dose can be achieved by dynamically adjusting the operating speed of the under-beam transmission system.

Objective To analyze the genetic characteristics and variations of influenza A (H3N2) viruses in Ma'anshan from 2022 to 2024, and to provide a scientific basis for local influenza prevention and control. Methods From April 2022 to March 2024, influenza-like illness (ILI) specimens were collected from three national influenza surveillance sentinel hospitals in Ma’anshan. Samples positive for influenza by real-time PCR were subjected to virus culture and identification. A total of 40 representative A/H3N2 strains with hemagglutination titers ≥8 were selected for whole-genome sequencing. Genetic evolution, homology, amino acid variations, and glycosylation sites were analyzed. Results All H3N2 representative strains from the 2022–2023 influenza season belonged to clade 3C.2a1b.2a.1a.1, while those from the 2023–2024 season fell into clade 3C.2a1b.2a.2a.3a.1. The nucleotide and amino acid sequence similarities of HA and NA between the 40 representative strains and the vaccine strain A/Darwin/6/2021 were all above 97.35%. Compared with the vaccine strain, amino acid mutations were identified in antigenic sites A, B, C, and E, as well as in receptor-binding sites of the HA protein. An I222V substitution was detected in the NA protein. The HA protein contained four additional glycosylation sites compared to the vaccine strain, while the glycosylation pattern of the NA protein remained consistent. Conclusion No antigenic drift was observed in the influenza A/H3N2 viruses in Ma'anshan City from 2022 to 2024, but genetic changes such as branching variations, key amino acid substitutions, and an increase in HA glycosylation sites were observed. These findings underscore the importance of sustained molecular surveillance of local influenza viruses.

ObjectiveTo observe the protective effect of Erchentang (ECT) on SiO2-induced lung injury in rats and to explore its underlying mechanism. MethodsA rat model of lung injury was established by a single intratracheal instillation of 50 mg·mL-1 SiO2 suspension. Thirty male Sprague-Dawley (SD) rats were randomly assigned to five groups: control, model, low and high-dose (4.5 g·kg-1·d-1 and 9 g·kg-1·d-1, respectively) ECT, and dexamethasone (0.2 mg·kg-1·d-1). All the groups were treated for 4 consecutive weeks. Histopathological alterations in the lung tissue were examined by hematoxylin and eosin (HE) staining. The levels of malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) in the lung tissue were measured through biochemical assays. The expression of key molecules in the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway was determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), Western blot, and immunofluorescence assay. The primary active components of ECT were identified by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and their binding affinity to Nrf2/HO-1 was assessed by molecular docking. Untargeted metabolomics of the lung tissue was performed based on UPLC-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS), and correlation analysis was performed to identify differential metabolites and parameters closely associated with the Nrf2/HO-1 pathway. ResultsCompared with the control group, the model group exhibited a reduction in body weight gain, an increase in lung index, increased MDA content, weakened SOD and GSH-Px activities in the lung tissue, down-regulated mRNA and protein levels of Nrf2 and protein levels of HO-1 and GPX4, and an up-regulated protein level of Keap1 (P<0.05, P<0.01). Treatment with ECT attenuated the SiO2-induced decline in body weight (P<0.05), alleviated inflammatory cell infiltration and silicotic nodule formation in alveoli, and reduced the MDA content and enhanced the SOD and GSH-Px activities in the lung tissue (P<0.05, P<0.01). UPLC-MS/MS and molecular docking revealed that core components of ECT, such as hesperidin and glycyrrhizic acid, displayed strong binding affinity to Nrf2/HO-1. Molecular biological experiments demonstrated that ECT promoted nuclear translocation of Nrf2, up-regulated the mRNA and protein levels of HO-1 and GPX4, and down-regulated Keap1 expression (P<0.05, P<0.01). Metabolomic analysis indicated that ECT reversed the SiO2-induced aberrant expression of metabolites, including linoleic acid and glutamine (P<0.05, P<0.01). Correlation analysis showed that Nrf2 and HO-1 were positively correlated with SOD and GSH-Px (P<0.05, P<0.01), but negatively correlated with glutamine and serine (P<0.05, P<0.01). ConclusionECT may activate the Nrf2/HO-1 pathway through its core active components, thereby regulating oxidative stress and metabolic disorders to ameliorate SiO2-induced lung injury in rats. This study provides experimental evidence for ECT in the prevention and treatment of occupational lung injury.

Strabismus, a common ocular condition, arises from an imbalance in the extraocular muscle force and deviation of the visual axis due to various factors. Concomitant strabismus is the predominant form of exotropia, with its pathogenesis believed to be associated with hereditary factors, abnormal eye accommodation function, and anomalies in binocular anatomy. Surgical intervention is often necessary for aligning the visual axes of both eyes and facilitating the recovery and establishment of stereoscopic vision. Despite this, the etiology of concomitant exotropia remains incompletely understood. This review consolidates recent research on aberrant molecular expression and pathological morphological changes within extraocular muscles affected by concomitant exotropia, offering insights into disease causation at molecular and pathological levels to underpin future preventive measures and clinical interventions. The discussion encompasses histological changes observed under electron microscopy as well as the impact of heavy chain protein, satellite cells, cadherin, growth factors on extraocular muscle protein expression.

Dendritic cells (DCs) serve as the primary antigen-presenting cells in autoimmune diseases, like rheumatoid arthritis (RA), and exhibit distinct signaling profiles due to antigenic diversity. Type II collagen (CII) has been recognized as an RA-specific antigen; however, little is known about CII-stimulated DCs, limiting the development of RA-specific therapeutic interventions. In this study, we show that CII-stimulated DCs display a preferential gene expression profile associated with migration, offering a new perspective for targeting DC migration in RA treatment. Then, saikosaponin D (SSD) was identified as a compound capable of blocking CII-induced DC migration and effectively ameliorating arthritis. Optineurin (OPTN) is further revealed as a potential SSD target, with Optn deletion impairing CII-pulsed DC migration without affecting maturation. Function analyses uncover that OPTN prevents the proteasomal transport and ubiquitin-dependent degradation of C-C chemokine receptor 7 (CCR7), a pivotal chemokine receptor in DC migration. Optn-deficient DCs exhibit reduced CCR7 expression, leading to slower migration in CII-surrounded environment, thus alleviating arthritis progression. Our findings underscore the significance of antigen-specific DC activation in RA and suggest OPTN is a crucial regulator of CII-specific DC migration. OPTN emerges as a promising drug target for RA, potentially offering significant value for the therapeutic management of RA.

The paper introduces the diagnostic and therapeutic ideas and clinical experience of Professor LIU Zhibin in treatment with acupuncture for Parkinson's disease with mild cognitive impairment. Professor LIU believes that the basic pathogenesis of Parkinson's disease with mild cognitive impairment refers to the deficiency of liver and kidney, and the loss of mind control. Therefore, the treatment focuses on nourishing the liver and kidney, regulating the governor vessel, opening the brain orifice, and regulating the mind. The point prescription is composed of Tongdu Tiaoshen zhen (the points for promoting the circulating of the governor vessel and regulating the mind, i.e. four-mind needles [Extra], Shenting [GV24], bilateral Benshen [GB13] and Fengfu [GV16]), xiusanzhen (three-olfaction needles, including bilateral Yingxiang [LI20] and Yintang [GV24+]) and zhichan bazhen (eight anti-tremble needles, i.e. Baihui [GV20], Lianquan [CV23], and Hegu [LI4], Waiguan [TE5], Taichong [LR3], Zusanli [ST36], Sanyinjiao [SP6] and Taixi [KI3] on the affected side). Besides, the prescription is modified according to the syndrome, and the special technique of bone-touching needling is combined to enhance the therapeutic effect.

This paper introduces Professor LIU Zhibin 's clinical experience in the treatment of subjective tinnitus with acupuncture based on the "kidney-bone-brain" axis. Professor LIU proposes that the disease is most closely related to the kidney and brain. The lesion is located in the brain, and the pathogenesis is kidney essence deficiency, marrow sea loss, and ear orifice dystrophy. The "kidney-bone-brain" shows close correlation in physiological function, pathological changes and treatment. According to the "kidney-bone-brain" axis, Professor LIU proposes that the treatment of subjective tinnitus should be tonifying kidney qi, tonifying essence and filling marrow, and the principle of local acupoint selection, touching bone acupuncture, matching distal acupoints and proximal acupoints, tonifying kidney and benefiting brain should be adopted. The acupoints of Tinggong (SI19) and Yifeng (TE17) are selected to be treated with touching bone acupuncture, combined with Taixi (KI3), Shenshu (BL23), Baihui (GV20) and Shenting (GV24), so as to achieve common benefit of kidney, bone and brain, and multi-angle treatment.

Chinese Journal of School Health 2025;46(4):494-499
Objective:
To analyze the consumption frequency of major foods among Chinese children aged 6-17 years old, and to provide a basis for optimizing the dietary structure of children in China.
Methods:
Using data from the China Nutrition and Health System Survey and Application Program for Children 0-18 years old, 56 734 children aged 6-17 years old from North, Norththeast East, Central, South, Southwest and Northwest seven regions in China were selected for the study using stratified cluster random sampling from 2019 to 2021. A food frequency questionnaire was used to investigate the intake frequency of eight food groups in a month, including fresh vegetables, fresh fruits, livestock and poultry meats, aquatic products, eggs, dairy products, legumes, and cereals and potatoes. The foods were grouped according to whether they met the recommended intake criteria outlined in the Dietary Guidelines for Chinese Residents 2022. The〖KG*2〗χ2 test was used to compare the differences in the proportion of childrens intake frequency of each food group meeting the standard in different regions and age groups.
Results:
The proportions of Chinese children aged 6-17 years who consumed fresh vegetables and cereals and potatoes ≥3 times/d were 12.1% and 67.2%, respectively. The proportions of children who consumed fresh fruits, livestock and poultry meats, eggs and dairy products ≥1 time/d were 50.8%, 58.8%, 36.0% and 54.3%, respectively. The proportion of legumes consumed ≥4 times/week was 37.4%, and the proportion of aquatic products consumed ≥2 times/week was 39.7%. Fresh vegetables (5.5%), fresh fruits (33.1%), and dairy products (36.4%) had the lowest frequency of meeting the recommended standards in South China, and aquatic products (27.4%) and eggs (21.1%) had the lowest frequency of meeting the recommended standards in Northwest (P<0.008 3).
Conclusion
The overall intake frequency of fresh vegetables, fresh fruits, legumes, and dairy products are insufficient among Chinese children, with significant regional variations.

ObjectiveTo investigate the therapeutic effects and mechanism of Shenqi Dihuang decoction (SQDHD) on diabetic kidney disease (DKD), with a focus on its impact on arachidonic acid-related ferroptosis. MethodsSixty C57BL/6 mice were allocated into a normal group (n=10) and a modeling group (n=50), with 43 mice successfully modeled. The successfully modeled mice were further allocated into model, low-, medium-, and high-dose (4.68, 9.36, and 18.72 g·kg-1, respectively) SQDHD, and dapagliflozin (0.13 mg·kg-1) groups. The drug treatment groups were administrated with corresponding agents by gavage, and the normal and model groups were administrated with equal volumes of normal saline by gavage. An electronic balance and a glucometer were used to monitor the body weight and fasting blood glucose level from the tail tip, respectively. Serum creatinine (Scr) and blood urea nitrogen (BUN) levels were measured by enzyme-linked immunosorbent assay (ELISA). Histopathological changes in the renal tissue were assessed by hematoxylin-eosin staining, Masson staining, and periodic acid-Schiff (PAS) staining. The fluorescence intensity of reactive oxygen species (ROS) in frozen sections was observed by an inverted fluorescence microscope to evaluate the levels of ferrous ions (Fe2+) and lipid peroxidation in the renal tissue. Immunofluorescence staining of glutathione peroxidase 4 (GPX4) and acyl-CoA synthetase long-chain family member 4 (ACSL4) in the renal tissue was performed to detect their localization and expression. Western blot was employed to assess the expression levels of key ferroptosis proteins such as GPX4 and cystine/glutamate antiporter (xCT), as well as the arachidonic acid metabolic pathway-related proteins, including ACSL4, lysophosphatidylcholine acyltransferase 3 (LPCAT3), and arachidonate 15-lipoxygenase (ALOX15). Real-time PCR was employed to measure the mRNA levels of key ferroptosis proteins, including solute carrier family 7 member 11 (SLC7A11) and GPX4, as well as arachidonic acid metabolism-related factors (ACSL4, LPCAT3, and ALOX15) in the renal tissue. ResultsCompared with the normal group, DKD model mice exhibited a decrease in body weight (P<0.01), increases in levels of blood glucose (P<0.01), 24-hour urinary protein, Scr, and BUN (P<0.01), along with severe pathological changes, such as mesangial cell proliferation, basement membrane thickening, tubular atrophy, and interstitial inflammatory cell infiltration. In addition, the modeling elevated the levels of Fe2+, MDA, LPO, and ROS (P<0.01), lowered the GPX4 and xCT levels (P<0.01), raised the ACSL4, LPCAT3, and ALOX15 levels (P<0.01), down-regulated the mRNA levels of GPX4 and SLC7A11 (P<0.01), and up-regulated the mRNA levels of ACSL4, LPCAT3, and ALOX15 (P<0.01) in the renal tissue. Compared with the model group, low-, medium-, and high-dose SQDHD groups and the dapagliflozin group showed an increase in body weight (P<0.01), decreases in levels of blood glucose (P<0.01), 24-hour urinary protein, and Scr (P<0.01), alleviated pathological changes in glomeruli and tubules, and reduced degree of glomerular and tubular fibrosis. The high-dose SQDHD group and the dapagliflozin group showed reductions in Fe2+, MDA, LPO, and ROS levels (P<0.01). The medium- and high-dose SQDHD groups and the dapagliflozin group exhibited increased levels of GPX4 and xCT (P<0.01), decreased levels of ACSL4, LPCAT3, and ALOX15 (P<0.05, P<0.01), and down-regulated mRNA levels of ACSL4, LPCAT3, and ALOX15 (P<0.01). ConclusionSQDHD ameliorates DKD by inhibiting ferroptosis potentially by reducing iron ion levels, inhibiting lipid peroxidation, up-regulating GPX4 expression, and down-regulating ACSL4 expression. This study provides new insights and a theoretical basis for the treatment of DKD with traditional Chinese medicine and identifies potential targets for developing novel therapeutics for DKD.
