Objective:To analyze the clinical characteristics, distribution of common pathogenic bacteria and drug resistance in children with non-chronic osteomyelitis, to provide a basis for empirical antimicrobial drug selection.Methods:This study was a retrospective analysis cohort study. Clinical data, pathogenic bacteria and drug sensitivity test results of 289 children aged 0 to 18 years with non-chronic osteomyelitis who were hospitalized in the Pediatrics Hospital of Fudan University from January 2013 to June 2023 were collected retrospectively. Statistical analyses were performed using chi-square test.Results:Of the 289 children, 188(65.1%) were male, with a male to female ratio of 1.86∶1, and the age was 3.00(0.66, 8.00) years. The age less than six years amounted 65.1% (188/289). The incidence was the highest from December to February of the following year, reaching 32.5%(94/289). The clinical manifestations were fever in 193 cases (66.8%), fever with localized pain in 47 cases (16.3%), and fever with localized swelling and fever with localized swelling and pain in 39 cases (13.5%) each. Single bone involvement was observed in 242(83.7%) cases, including 88(36.4%) femur, 47(19.4%) tibia, and 37(15.3%) humerus. Of the 130 pathogen-positive cases, 102(78.5%) were Staphylococcus aureus (SA) including 45(44.1%) methicillin-resistant Staphylococcus aureus (MRSA), 10(7.7%) were Pseudomonas aeruginosa, and 3(2.3%) each were Klebsiella pneumoniae and Staphylococcus mansoni. The rate of MRSA detection in SA fluctuated each year from 2013 to 2023, with the highest in 2017, when eight out of 13 SA cases were MRSA. The resistance rates of all SA to vancomycin, linezolid, moxifloxacin, ciprofloxacin, gentamicin, rifampicin, ceflorin, tigecycline, ticlosporin, fosfomycin, daptomycin, furotoxin, quinupristin/dalfopristin were all zero, and the differences in resistance rates of methicillin-susceptible Staphylococcus aureus (MSSA) and MRSA to cefazolin, cefuroxime, benzoxiline, ampicillin/sulbactam, and clindamycin were all statistically significant ( χ2=68.91, 68.91, 82.00, 68.91 and 9.20, respectively, all P<0.05). Intravenous anti-infective treatment was administered for 24(35, 47) days in 289 children with osteomyelitis, for a total duration of 42.00(35.00, 47.00) days. After treatment, 287 cases (99.3%) were discharged with improvement, while two cases (0.7%) died. One death was due to phagocytosis syndrome and septic shock, and the other death was due to septic shock and multiple organ dysfunction. Conclusions:Non-chronic osteomyelitis in children is most common in male children under six years old, and the most common sites are femur, tibia and humerus. The main clinical manifestations are fever, localized swelling and pain. SA was the most common causative agent. No SA strain resistant to vancomycin, linezolid, moxifloxacin, ciprofloxacin, gentamicin, rifampicin, ceflorin, tigecycline, ticlosporin, fosfomycin, daptomycin, furotoxin, quinupristin/dalfopristin is found.

AIM To investigate the effects of Rutong Ruanjian Tablets on angiogenesis in cancer tissues of rats with preneoplastic breast cancer(PBC).METHODS 60 female SD rats were randomly divided into a blank group of 10 rats and a model group of 50 rats for the establishment of the PBC models of Liver-Qi Stagnation and Blood Stasis Pattern with 9 weeks of oral administration of 7,12-dimethylbenz[a]anthracene(DMBA)and cervical ligation.After successful modeling,the rats were randomly divided into the model group,the tamoxifen group(3.2 mg/kg),the Rutong Ruanjian Tablets group(128 mg/kg),the 3,5-difluorobenzoyl group(DAPT,5 mg/kg),and the Rutong Ruanjian Tablets(128 mg/kg via gavage)+DAPT(5 mg/kg intraperitoneal injection)group,for 1 month corresponding drug administration,with 10 rats in each group.Then the rats had their cancer progression and syndrome scores observed;their angiogenesis evaluated by assessment of microvascular density(MVD);their vascular endothelial growth factor(VEGF)expression assessed by immunohistochemistry;and their mRNA and protein expressions of proteins related to the DLL4/Notch1/Hes1 pathway measured using RT-qPCR,immunohistochemistry and Western blot.RESULTS During carcinogenesis of rats induced by DMBA,there was gradual disappearance of E-cadherin expression and consistency of HE staining result with the PBC progression confirming the success of the modeling.Compared with the blank group,the model group showed increased MVD values,mRNA expression of Notch1 and Hes1,and protein expressions of VEGF,DLL4,Notch1 and Hes1(P＜0.05,P＜0.01).Compared with the model group,the Rutong Ruanjian Tablets group exhibited reduced MVD values,mRNA expression of Notch1 and Hes1,and protein expressions of VEGF,DLL4,Notch1 and Hes1(P＜0.05,P＜0.01).The Rutong Ruanjian Tablets+DAPT group showed reduced mRNA expression of Notch1 and Hes1,and protein expressions of DLL4,Notch1 and Hes1 compared to the Rutong Ruanjian Tablets group(P＜0.05,P＜0.01).CONCLUSION Rutong Ruanjian Tablets can inhibit angiogenesis and attenuate cancer progression in PBC rats of Liver-Qi Stagnation and Blood Stasis Pattern,and the mechanism may lie in the downregulation of DLL4/Notch1/Hes1 signaling pathway related proteins.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

OBJECTIVE: To investigate the anti-tumor effects of cinobufacini (CINO) on hepatocellular carcinoma (HCC) induced by des-gamma-carboxy-prothrombin (DCP) and to uncover the underlying mechanisms. METHODS: The inhibitory effect of CINO on HCC cell proliferation was evaluated using the cell counting kit-8 method, and the apoptosis rate was quantified using flow cytometry. Immunofluorescence and Western blot analyses were used to investigate the differential expression of proteins associated with cell growth, apoptosis, migration, and invasion pathways after CINO treatment. The therapeutic potential of CINO for HCC was confirmed, and the possibility of combining cinobufacini with c-Met inhibitor for the treatment of primary HCC was further validated by in vivo experiments. RESULTS: Under the induction of DCP, CINO inhibited the activity of HCC cells, induced apoptosis, and inhibited migration and invasion. Upon the induction of DCP, CINO regulated c-Met activation and the activation of the phosphatidylinositol-3 kinase/protein kinase B (PI3K/AKT) and mitogen-activated protein kinase kinase/extracellular signal-regulated kinase (MEK/ERK) pathways. In a mouse model of HCC, CINO exhibited significant antitumor effects by inhibiting the phosphorylation of c-Met and the downstream PI3K/AKT and MEK/ERK pathways in tumor tissues. CONCLUSIONS CINO inhibited HCC cell growth, promoted apoptosis, and suppressed HCC cell invasion and migration by targeting c-Met and PI3K/AKT and MEK/ERK signaling pathways under DCP induction.
