Excessive exercise can lead to fatigue, consequently affect exercise performance, and further have an adverse impact to human health. The synergistic effects of ginsenosides, salidroside, and syringin on improving exercise performance remain unknown. Hence, the effects of Chinese herb powder (CHP) which consisted of bioactive compounds such as ginsenosides (Rg1, Re, and Rb1), salidroside, and syringin on exercise performance, energy metabolism, tissue damage, antioxidant activity, and inflammatory cytokine were investigated in exhaustive exercise rats. ⋯ Abdominal arterial blood, liver, and gastrocnemius muscles were collected 4 hours after exhaustive exercise for further analysis. The high-dose CHP group increased the time to exhaustion, decreased serum lactate level, increased serum superoxide dismutase activity, and decreased liver interleukin-6 concentration. Therefore, CHP exhibits an anti-fatigue effect for prolonging the time to exhaustion through improving lactate clearance, and to a lesser extent, enhancing the capacity of antioxidation and anti-inflammation.

Introduction: Live microorganisms, named probiotics, can improve overall physical well-being, particularly the oral cavity's health. L. casei Shirota, a popular probiotic, can influence the immune response by increasing the number of macrophages and plasma cells that play a role in traumatic ulcer healing. Aims: To determine the expression of tumor necrosis factor-alpha (TNF-α) and the varied number of plasma cells and macrophages on a traumatic ulcer animal model treated with topical or systemic administration of a probiotic L. casei Shirota. ⋯ Results: The Mann-Whitney and Tukey HSD tests indicated significant differences (p < 0.05) in the results for the three groups. It was observed that topical administration provides more remarkable results than systemic administration for the expression of TNF-α, the number of plasma cells, and the number of macrophages. Conclusion: Topical administration of L. casei Shirota demonstrates better results than systemic administration for healing traumatic ulcers.

Background: The lengthy period of external fixation for bone consolidation increases the risk of complications during distraction osteogenesis (DO). Both pro-angiogenic and osteogenic potential of bone marrow mesenchymal stem cells (BMSCs) contribute to bone regeneration during DO. The underlying mechanism of Schwann cells (SCs) in promoting bone regeneration during DO remains poorly understood. ⋯ Furthermore, RSC-96 derived CM accelerated bone regeneration, resulting in improved biomechanical parameters, radiological features and histological manifestations, along with increased vascularization in the distraction area. Conclusion: Through activation of AKT/GSK-3β/β-catenin signaling, SCs enhanced the coupled angio- and osteogenesis effects of BMSCs. The preclinical evidence demonstrates that SCs derived CM with increased neurotrophins secretion can be a promising treatment approach to accelerate bone regeneration in the DO process.

Review Meta Analysis
Differences of the Chest Images Between Coronavirus Disease 2019 (COVID-19) Patients and Influenza Patients: A Systematic Review and Meta-analysis.
Background: Coronavirus disease 2019 (COVID-19) and influenza are two infectious diseases that can pose a great threat to human health. We aimed to compare the differences in chest images between patients with COVID-19 and influenza to deepen the understanding of these two diseases. Methods: We searched PubMed, Embase and Web of Science for articles published before December 25, 2023, and performed a meta-analysis using Stata 14.0 with a random-effects model. ⋯ Patients with COVID-19 showed more ground-glass opacities (OR=2.83, 95% CI: 1.85-4.32), reverse halo signs (OR=3.47, 95% CI: 2.37-5.08), interlobular septal thickening (OR=2.16, 95% CI: 1.55-3.01), vascular enlargement (OR=5.00, 95% CI: 1.80-13.85) and crazy-paving patterns (OR=2.63, 95% CI: 1.57-4.41) on chest images than patients with influenza. We also found that compared with influenza patients, pleural effusion was rare in COVID-19 patients (OR=0.15, 95% CI: 0.07-0.31). Conclusions: There are some differences in the manifestations and distributions of lesions between patients with COVID-19 and influenza on chest images, which is helpful to distinguish these two infectious diseases.

Review Case Reports
Investigating the Process of Autoimmune Inner Ear Disease: Unveiling the Intricacies of Pathogenesis and Therapeutic Strategies.
Autoimmune inner ear disease (AIED) is a rare condition characterized by immune-mediated damage to the inner ear, leading to progressive sensorineural hearing loss (SNHL) and vestibular symptoms such as vertigo and tinnitus. This study investigates the pathogenesis and therapeutic strategies for AIED through the analysis of three cases with different underlying autoimmune disorders: rheumatoid arthritis, relapsing polychondritis, and IgG4-related disease. The etiology of AIED involves complex immunopathological mechanisms, including molecular mimicry and the "bystander effect," with specific autoantibodies, such as those against heat shock protein 70 (HSP70), playing a potential role in cochlear damage. ⋯ Early intervention is crucial for favorable outcomes, as demonstrated in the studied cases, where timely corticosteroid and immunosuppressive treatments led to significant hearing improvement. The study underscores the importance of personalized treatment strategies based on individual immunologic profiles and comorbidities. Our findings highlight the heterogeneity of AIED and the potential for biologic therapies in refractory cases.
