Osteosarcoma is the most common primary malignant bone tumor in children and adolescents with a peak incidence between the ages of 10 and 20. It has an extremely high mortality and disability rate. In adults, osteosarcoma is the third most common bone tumor. Despite the advances in chemotherapy, surgical techniques, and radiotherapy that have significantly improved the overall survival rate of osteosarcoma, the long-term prognosis of patients has not shown substantial improvement, especially in cases of tumor metastasis and recurrence. Due to the highly invasive growth of tumor cells, the progression of osteosarcoma is often accompanied by the destruction of surrounding bone tissue and the formation of immature new bone, making treatment challenging, especially in tissue repair and functional recovery following surgical resection. Tumor resection surgery often results in extensive bone loss, particularly in cases involving joints or weight-bearing areas, making the reconstruction of bone structure and function highly complex. Currently, inert materials such as stainless steel or titanium alloy prostheses used in clinical practice exhibit poor biocompatibility and high elastic modulus, often leading to prosthesis loosening and infection. There is an urgent clinical need for multifunctional biomaterials capable of both repairing bone defects and inhibiting tumor recurrence. Magnesium-based biomaterials have shown excellent biodegradability and bioactivity, and the release of magnesium ions and degradation products effectively promotes bone tissue regeneration while demonstrating potential antitumor effects. This paper reviews the application of magnesium-based biomaterials in the treatment of bone defects associated with osteosarcoma, including their adaptation to the acidic conditions of the osteosarcoma microenvironment, their potential to promote osteogenesis, and their antitumor mechanisms. It also analyzes the mechanical compatibility of magnesium-based materials and the use of coating technologies to enhance their corrosion resistance, and explores the prospects of various types of magnesium-based compounds in the treatment of osteosarcoma-related bone defects.

Objective:To investigate the effects of intermittent theta burst stimulation(iTBS)on the static balance and walking function in patients with subacute stroke.Method:Twenty-eight patients with subacute stroke were randomly divided into 2 groups(14 cases in the ex-perimental group and 14 cases in the control group).Both groups received rehabilitation training.The experi-mental group received 10 times iTBS targeting the lateral cerebellar region of the hemiplegic side for 2 weeks,while the control group received sham iTBS.Patients in both groups were assessed for standing or walking tasks before and after treatment.Static balance data were collected using the Prokin balance testing instrument during standing tasks.For walking tasks,gait parameters were recorded using the Vicon motion capture system.Repeated-measures ANOVA was used to compare balance and gait data between the two groups before and af-ter the treatment.Result:No significant differences were observed in baseline characteristics,balance function,or walking func-tion between the two groups before treatment(P＞0.05).After treatment,the experimental group showed signifi-cant improvements in balance function,including reduced average sway velocity of the center of pressure in the anterior-posterior direction(P＜0.001),decreased sway area of the center pressure(P＜0.001),and the shorter trajectory path length of the center pressure(P＜0.001).In contrast,the control group exhibited no sig-nificant changes(P＞0.05).Regarding walking function,the experimental group demonstrated a significant in-crease in step frequency(P＜0.001),while the control group showed no significant change(P＞0.05).Conclusion:Cerebellar iTBS can effectively enhance static balance and walking function in patients with sub-acute stroke.

The chi-square test was used for comparison of categorical data between groups， and the unordered polytomous logistic regression model was used to investigate the influencing factors for TCM syndromes of liver cancer. ResultsThe common initial symptoms of the 415 patients with primary liver cancer included pain in the liver area （31.81%）， abdominal distension （25.30%）， abdominal pain （15.18%）， and weakness （13.98%）， and the main clinical symptoms included poor appetite （70.84%）， fatigue （69.16%）， pain in the liver area （67.47%）， poor sleep （59.04%）， abdominal distension （53.01%）， and constipation （52.53%）. There were significant differences in TCM syndromes between patients with different sexes， courses of the disease， clinical stages， Child-Pugh classes， presence or absence of intrahepatic and extrahepatic metastasis， and presence or absence of transcatheter arterial chemoembolization （TACE） and radiofrequency ablation （all P<0.05）. The logistic regression analysis showed that male sex was a risk factor for damp-heat accumulation （odds ratio ［OR］=2.036， P=0.048） and the syndrome of spleen-kidney Yang deficiency （OR=5.240， P<0.001）； a course of disease of<1 year was a risk factor for damp-heat accumulation （OR=2.837， P=0.004） and syndrome of Qi stagnation and blood stasis （OR=2.317， P=0.021）， but it was a protective factor against syndrome of spleen-kidney Yang deficiency （OR=0.385， P=0.005）； Child-Pugh class A/B was a protective factor against liver-kidney Yin deficiency （OR=0.079， P<0.001）； intrahepatic metastasis was a risk factor for liver-kidney Yin deficiency （OR=5.117， P=0.003） and syndrome of spleen-kidney Yang deficiency （OR=3.303， P=0.010）； TACE was a protective factor against liver-kidney Yin deficiency （OR=0.171， P<0.001） and syndrome of spleen-kidney Yang deficiency （OR=0.138， P<0.001）； radiofrequency ablation was a risk factor for damp-heat accumulation （OR=4.408， P<0.001） and liver-kidney Yin deficiency （OR=32.036， P<0.001）. ConclusionSex， course of disease， Child-Pugh class， intrahepatic metastasis， TACE， and radiofrequency ablation are the main influencing factors for TCM syndromes of liver cancer.

Objective:This study aims to investigate the differences in emotional status and cognitive function among patients with vestibular migraine (VM), Meniere′s disease (MD), and their comorbidity (VMMD), and to analyze key factors influencing cognitive function.Methods:This cross-sectional study included 96 outpatients (32 males, 64 females, aged 21-73 years) from the Department of Otorhinolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, between December 2022 and December 2023. The study population consisted of 31 VM patients (VM group), 36 MD patients (MD group), and 29 VMMD patients (VMMD group), along with 32 healthy controls (16 males, 16 females, aged 19-74 years). Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), while emotional status and somatization symptoms were evaluated through the Generalized Anxiety Disorder scale, Patient Health Questionnaire Depression scale, Symptom Checklist-90, and the Self-rating Somatization Symptom scale. Multiple linear regression analysis was conducted to explore the influence of different variables on cognitive function.Results:The total MoCA score in the VMMD group (26.0 [24.5, 28.0]) was significantly lower than that in the control group (28.0 [27.0, 29.0]) and the MD group (28.0 [26.0, 30.0]) ( P=0.006). VMMD patients exhibited significant impairments in specific cognitive domains, including visuospatial/executive function, delayed recall, and orientation ( P<0.05). Patients with VM, MD, and VMMD showed higher rates of anxiety, depression, and somatization symptoms compared to the control group ( P<0.05), with the VMMD group experiencing the most severe emotional distress. Multiple linear regression analysis identified education level and vestibular disease type as key factors affecting cognitive function, with a university-level education predicting higher MoCA scores ( P<0.001), while VMMD was associated with cognitive decline ( P<0.01). Conclusions:Patients with VM and MD, particularly those with comorbid VMMD, exhibit significant emotional distress. Cognitive impairments are present in VM and VMMD patients, affecting different cognitive domains. These factors should be comprehensively considered in clinical assessments to develop more effective treatment strategies.

Objective:This study aimed to explore the molecular mechanisms of the maladaptation of H3N2 influenza virus in chicken embryos, provide a theoretical basis for the restoration of H3N2 influenza vaccine production in chicken embryos.Methods:Samples of respiratory secretions from patients with influenza-like symptoms (Influenza-like Illness, ILI) caused by H3N2 influenza virus were inoculated into chicken embryos and Madin-Darby Canine Kidney cells (MDCK), respectively. After isolating the virus, hemagglutination experiments were conducted to detect hemagglutination titers and hemagglutination inhibition experiments were used to compare antigenic differences; further, whole-genome sequencing of H3N2 influenza virus was performed using second-generation high-throughput gene sequencing (Next Generation High-Throughput Gene Sequencing, NGS), and key amino acid sites of mutations were identified through sequence alignment; combined with sialic acid receptor binding experiments, the differences in the binding of wild-type and mutant receptor binding sites (RBS) to sialic acid receptors were compared; finally, molecular docking and molecular dynamics simulation method were used to explore the specific molecular mechanisms of how mutation sites affect the differences in the affinity of the RBS pocket for sialic acid receptors.Results:The hemagglutination assay result indicated that both chicken embryos and MDCK cells could isolate the influenza virus, and the hemagglutination inhibition test showed that no antigenic differences were produced in the isolated strains. NGS analysis revealed that the H3N2 virus underwent an F195Y mutation in the (RBS) region of the hemagglutinin (HA) protein after adaptation through chicken embryo passages. Receptor-binding experiments demonstrated that the F195Y mutation enhanced the virus′s binding ability to α2, 3-linked sialic acid glycan (Neu5Acα2-3Galβ1-4GlcNAcβ-PAA, 3′SLN), while the mutation did not affect the affinity of the RBS pocket for α2, 6-linked sialic acid glycan (Neu5Acα2-6Galβ1-4GlcNAcβ-PAA, 6′SLN). Molecular docking and molecular dynamics simulation result indicate that the F195Y mutation, by replacing a hydrophobic amino acid with a hydrophilic one, leads to a significant decrease in the structure of the RBS pocket, enhancing the binding stability of the H3N2 influenza virus with α2, 3-sln. This is specifically manifested by an increase in binding time and an increase in the number of hydrogen bonds at the RBS site with the receptor. Furthermore, the F195Y mutation does not alter the binding of the virus to other receptors.Conclusions:The F195Y mutation in the RBS pocket of H3N2 influenza virus is a key site affecting the viral chicken embryo inadaptability.
