BACKGROUND:In recent years,numerous studies have shown that autophagy and mitophagy play an important role in the regulation of bone metabolism.Under non-physiological conditions,mitophagy breaks the balance of bone metabolism and triggers metabolism disorders,which affect osteoblasts,osteoclasts,osteocytes,chondrocytes,bone marrow mesenchymal stem cells,etc. OBJECTIVE:To summarize the mechanism of mitophagy in regulating bone metabolic diseases and its application in clinical treatment. METHODS:PubMed,Web of Science,CNKI,WanFang and VIP databases were searched by computer using the keywords of"mitophagy,bone metabolism,osteoblasts,osteoclasts,osteocytes,chondrocytes,bone marrow mesenchymal stem cells"in English and Chinese.The search time was from 2008 to 2023.According to the inclusion criteria,90 articles were finally included for review and analysis. RESULTS AND CONCLUSION:Mitophagy promotes the generation of osteoblasts through SIRT1,PINK1/Parkin,FOXO3 and PI3K signaling pathways,while inhibiting osteoclast function through PINK1/Parkin and SIRT1 signaling pathways.Mitophagy leads to bone loss by increasing calcium phosphate particles and tissue protein kinase K in bone tissue.Mitophagy improves the function of chondrocytes through PINK1/Parkin,PI3K/AKT/mTOR and AMPK signaling pathways.Modulation of mitophagy shows great potential in the treatment of bone diseases,but there are still some issues to be further explored,such as different stages of drug-activated mitophagy,and the regulatory mechanisms of different signaling pathways.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Glioma is the most common primary malignant tumor of the central nervous system in adults. Despite the standard treatment of surgery combined with radiotherapy and chemotherapy, the prognosis for high-grade glioma patients remains poor, highlighting the urgent need to further explore its pathogenesis and develop new therapeutic strategies. This article reviews the research progress in the field of glioma in China in 2024, covering tumorigenesis mechanisms, tumor immune microenvironment composition, advances in imaging techniques and novel imaging agents, improvements in surgical approaches, mechanisms of radio- and chemoresistance, and explorations of new therapeutic modalities. These studies provide a solid theoretical foundation for advancing clinical diagnosis and treatment of gliomas and may offer new opportunities to improve patient outcomes.

AIM:To predict the mechanism of Sanguis draconis flavones(SDF)in the prevention and treat-ment of myocardial ischemia reperfusion injury(MIRI)based on network pharmacology and molecular docking methods.METHODS:The main chemical constituents of SDF were collected through literature search,and the targets of key con-stituents were screened by using the SwissTargetPrediction and TargetNet databases.Disease targets were also screened based on GeneCards,OMIM,TTD and PharmGkb databases,then targets were intersected with Cytoscape to construct the"drug-key constituent-target"network diagram,and the core target was obtained through visualization and analysis by Cytoscape software.Gene Ontology(GO)functional enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses were analyzed by the Metascape platform.By utilizing AutoDock Vina software and Pymol,molecular docking between core compounds and core targets was carried out.Further,animal experiments were performed to explore the pharmacodynamic mechanism of SDF.RESULTS:The active constituents of SDF included loureirin B and loureirin A,which were mapped to 391 targets.A total of 3 096 MIRI disease targets were obtained from the database,af-ter intersection,172 intersection targets were obtained,and 56 core targets were acquired through analysis.The core relat-ed pathways included the cancer pathway and cell death signaling pathway.The results of molecular docking verified the strong binding activity between key constituents and key targets.Animal experiments demonstrated that SDF effectively prevented and treated MIRI,significantly inhibited the arachidonic acid 15-lipoxygenase(ALOX15)mRNA and protein expression,and reduced the myocardial infarction size after MIRI.CONCLUSION:SDF may play a positive role in the treatment of MIRI,which may be related to the regulation of the ALOX15 factor.

Objective:To explore the clinical characteristics of interleukin-6 (IL-6) and interleukin-8 (IL-8) in cerebrospinal fluid (CSF) of children with bacterial meningitis (BM) and provide reference for clinical diagnosis and treatment of BM.Methods:The clinical data of BM children hospitalized in Women and Children′s Medical Center Affiliated to Guangzhou Medical University from December 2019 to March 2022 were collected and retrospectively analyzed in this case series study.Cytokines in CSF of these children were detected at least twice during the treatment. t test, Mann-Whitney test or analysis of variance were carried out for statistical analysis. Results:There were 40 patients included in this study.The age of onset was 2(1, 8) months, ranging from 2 days to 8 years, and the length of time from onset to hospitalization was (15±17) days, ranging from 1 day to 69 days.The main symptoms at the onset were fever (40 cases, 100%), poor mental state (16 cases, 35.0%), convulsion (9 cases, 22.5%), and vomiting (9 cases, 22.5%).According to pathogens, the patients were divided into the Streptococcus agalactia group (GBS group, 9 cases), Streptococcus pneumoniae group (SP group, 9 cases), other bacteria group (9 cases), and unknown bacteria group (13 cases).The levels of cytokines in the CSF of BM children were increased, along with significantly elevated levels of IL-6 and IL-8 within 1 st week of BM, followed by the peak at 2 nd-3 rd weeks, and then levels of IL-6 and IL-8 presented an overall decreasing trend with the progression of BM.The level of IL-6 in CSF of 10 cases significantly decreased in the 4 th week of BM [within 2 weeks: 773.5(164.1, 1 781.2) ng/L vs. 4 th week: 10.8(2.2, 21.1) ng/L, P=0.005].Such statistical differences didn′t occur to the level of IL-8 [within 2 weeks 182.9(33.6, 657.7) ng/L vs. 4 th week: 92.9(22.6, 226.6) ng/L, P=0.303].After effective antibiotic therapy, 6 patients had elevated white blood cell count in CSF during the 4 th-20 th weeks, with or without repeating intermittent fever.Among them, 4 cases of GBS and 1 case of SP were negative for pathogens in CSF during the retest after treatment, and the levels of IL-6 and IL-8 [(149.1-4 218.6) ng/L and (124.2-1 890.3) ng/L, respectively] in CSF were elevated.Low-dose glucocorticoid was administered for anti-inflammatory treatment, with additional gamma globulin for 1 case and Ibuprofen instead for 1 case.Subsequently, the fever completely subsided.The white blood cell count in CSF decreased significantly ( P=0.024). Conclusions:The levels of IL-6 and IL-8 in CSF increase significantly in the acute phase of BM and generally decrease with the progression of BM.If they are still significantly elevated in the later course of BM, it should be noted that an intracranial hyperinflammatory response may occur, especially when the pathogenic bacteria are GBS or SP.

Objective:To explore the effects of adenoid hypertrophy on the growth and development of cranio-maxillofacial hard tis-sues in children at different growth stages.Methods:The cephalic lateral images of 232 children aged 4 to 16 years were measured and analyzed by Bjork-Jarabak cephalometric analysis.The patients were divided into 3 groups:CVM 1-2(A),CVM 3-4(B)and CVM 5-6(C)according to cervical vertebral maturation(CVM).Adenoid hypertrophy group and normal group were set up by Adenoi-dal-Nasopharyngeal Ratio(A/N Ratio)of 0.61.A,B and C groups included 28,55 and 23 cases in the subjects with adenoid hyper-trophy,and 12,65 and 49 cases in those of normal controls respectively.T-test was used to explore the difference of growth and devel-opment measurements among different subgroups of the same CVM stage and the change trend of the difference in different CVM sta-ges.Results:Hypertrophic adenoid children's S-Ar,N-Me and S-Ar/Ar-Go were significantly larger in CVM 1-2 subjects(P＜0.05);Ar-Go-Me,N-S-Ar and Ar-Go-N were significantly larger in CVM 5-6 subjects(P＜0.05),while S-Ar-Go decreased significantly(P＜0.05);S-N,Go-Me,S-Go,S-N/Go-Me and Ar-Go/N-Me had no significant differences in the whole stages(P＜0.05).Conclu-sion:Adenoid hypertrophy has great effect on the cranio-maxillofacial growth trend.It induces more posterior position of condyle,tilt-ing back of mandibular ramus,vertical growth and clockwise rotation of the mandible and incline to form class Ⅱ malocclusion.The effects are more prominant in early and late growth and development stages of the children.

Objective To analyze the medication law of national TCM master Gan Zuwang in the treatment of rhinitis using multivariate techniques.Methods The clinical cases of Professor Gan Zuwang's treatment of rhinitis from Jiangsu Province Hospital of Chinese Medicine from April 1984 to February 2001 were selected.Frequency statistics,co-occurrence frequency,association rules,dosage analysis and clustering analysis were used to reveal potential relationships between drugs from multiple perspectives,which were combined with the visual results of heat map,spectrogram,complex network,etc.,for intuitive presentation.Results Totally 1 080 medical cases were included,involving 1 044 prescriptions and 281 kinds of Chinese materia medica.The high-frequency drugs included Magnoliae Flos,Atractylodis Macrocephalae Rhizoma,Angelicae Dahuricae Radix,etc.;the tastes were mainly sweet,bitter and pungent,and their properties were mainly cold and warm,and most of them were classified into the lung meridian and the liver meridian.The top three drug efficacy classifications were antidepressants,purgatives and deficiency tonics.And substitute food for medicine,adding water chestnuts,jellyfish,kelp appeared in low-frequency drugs.In addition,Saposheikovize Radix-Astragali Radix-Atractylodis Macrocephalae Rhizoma,Xanthii Fructus-Menthae Haplocalycis Herba-Magnoliae Flos-Angelicae Dahuricae Radix were the core pairs,the dosage of Acori Tatarinowii Rhizoma and Angelicae Dahuricae Radix was more discrete,and the dosage of Poria was lower than the latest standardized value.Four types of formulas were finally obtained through comprehensive analyses:Yupingfeng Powder and Tuomin Decoction were used for the treatment of allergic rhinitis,Cangerzi Powder and Biyuan Mixture were used for the treatment of nasosinusitis,Shengqing Liuqi Decoction was used for the treatment of tinnitus,and Sijunzi Decoction,Senling Baizhu Powder,Yigong Powder and Buzhong Yiqi Decoction were used to strengthen spleen and tonify qi.Conclusion This study delves into the potential association between drugs and comprehensively explores Professor Gan Zuwang's medication experience in the treatment of rhinitis,which compensates for the high-frequency limitation and data bias of a single study.

Purpose: The risk stratification of pediatric anaplastic large cell lymphoma (ALCL) has not been standardized. In this study, new risk factors were included to establish a new risk stratification system for ALCL, and its feasibility in clinical practice was explored. Materials and Methods: On the basis of the non-Hodgkin’s lymphoma Berlin–Frankfurt–Munster 95 (NHL-BFM-95) protocol, patients with minimal disseminated disease (MDD), high-risk tumor site (multiple bone, skin, liver, and lung involvement), and small cell/lymphohistiocytic (SC/LH) pathological subtype were enrolled in risk stratification. Patients were treated with a modified NHL-BFM-95 protocol combined with an anaplastic lymphoma kinase inhibitor or vinblastine (VBL). Results: A total of 136 patients were enrolled in this study. The median age was 8.8 years. The 3-year event-free survival (EFS) and overall survival of the entire cohort were 77.7% (95% confidence interval [CI], 69.0% to 83.9%) and 92.3% (95% CI, 86.1% to 95.8%), respectively. The 3-year EFS rates of low-risk group (R1), intermediate-risk group (R2), and high-risk group (R3) patients were 100%, 89.5% (95% CI, 76.5% to 95.5%), and 67.9% (95% CI, 55.4% to 77.6%), respectively. The prognosis of patients with MDD (+), stage IV cancer, SC/LH lymphoma, and high-risk sites was poor, and the 3-year EFS rates were 45.3% (95% CI, 68.6% to 19.0%), 65.7% (95% CI, 47.6% to 78.9%), 55.7% (95% CI, 26.2% to 77.5%), and 70.7% (95% CI, 48.6% to 84.6%), respectively. At the end of follow-up, one of the five patients who received maintenance therapy with VBL relapsed, and seven patients receiving anaplastic lymphoma kinase inhibitor maintenance therapy did not experience relapse. Conclusion This study has confirmed the poor prognostic of MDD (+), high-risk site and SC/LH, but patients with SC/LH lymphoma and MDD (+) at diagnosis still need to receive better treatment (ClinicalTrials.gov number, NCT03971305).

Depression is a mental disorder with high morbidity, disability and relapse rates. Ginkgo biloba extract (GBE), a traditional Chinese medicine, has a long history of clinical application in the treatment of cerebral and mental disorders, but the key mechanism remains incompletely understood. Here we showed that GEB exerted anti-depressant effect in mice through regulating gut microbial metabolism. GBE protected against unpredictable mild stress (UMS)-induced despair, anxiety-like and social avoidance behavior in mice without sufficient brain distribution. Fecal microbiome transplantation transmitted, while antibiotic cocktail abrogated the protective effect of GBE. Spatiotemporal bacterial profiling and metabolomics assay revealed a potential involvement of Parasutterella excrementihominis and the bile acid metabolite ursodeoxycholic acid (UDCA) in the effect of GBE. UDCA administration induced depression-like behavior in mice. Together, these findings suggest that GBE acts on gut microbiome-modulated bile acid metabolism to alleviate stress-induced depression.
