Objective: To conduct an intensive investigation of the abnormal immune status of patients with primary hepatocellular carcinoma and explore the possible mechanism of biotherapy for these patients.
Methods: The expression of tumor necrosis factor receptor (TNFR)I and TNFR II on peripheral blood mononuclear cells (PBMCs) obtained from 30 normal subjects and 31 patients with primary hepatocellular carcinoma were examined by flow cytometry and S-P staining assay. The effects of biotherapy and chemotherapy administered in the patients were also investigated in terms of the changes in the expressions.
Results: The TNFR I and TNFR II expressions in the patients were (28.35+/-9.09) % and (37.45+/-9.51) % respectively, significantly lower than those of normal subjects [(38.54+/-8.51) % and (44.89+/-9.08) %]. The biotherapy for the patients caused an increase of TNFR I expression to (42.86+/-9.02)%.
Conclusion: There are significant immune abnormalities in patients with primary hepatocellular carcinoma, and this study may offer some theoretical basis for the implementation of biotherapy in such cases.

Intrauterine Adhesions (IUA) are a significant cause of infertility and miscarriage, often resulting from trauma to the endometrium. While hysteroscopic adhesiolysis is the primary treatment, the use of hydrogels as anti-adhesion barriers and drug delivery systems is gaining traction for improving patient outcomes. This review aims to explore various hydrogel types, their role in tissue repair, and the integration of stem cell therapy.

Open abdomen treatment (OAT) is associated with significant morbidity and mortality. In cases where primary or delayed fascial closure cannot be achieved, vacuum-assisted wound closure and mesh-mediated fascial traction are indicated, which often result in a planned ventral hernia. If secondary skin closure is not feasible, common treatment of granulated abdominal defects involves split-thickness skin-grafting or healing by secondary intention leading to significant scarring and sometimes mutilating defects.

Introduction: The current standard of care of patients with spondyloarthritis (SpA), in addition to pharmacological treatment, includes regular exercise and patient education.(1) The primary goal of this systematic literature review (SLR) is to update the evidence of the effectiveness of education programs for patients with axial SpA (axSpA).
Methods: We systematically searched three databases, PubMed, Embase and Web of Science Core Collection, from January 2000 to June 2023, using the following terms: "patient education", "patient counselling", "patient teaching", "patient engaging", "patient empowerment", "health education", "spondyloarthritis", "spondyloarthropaties", "spondylitis" and "ankylosing spondylitis".
Background: Axial Spondyloarthritis (axSpA) is a chronic inflammatory rheumatic condition affecting the axial skeleton, leading to pain, stiffness, and fatigue. While biologic therapies have improved clinical management, many patients experience partial or no responses, resulting in delays in disease control. Additionally, the risk of adverse events and increased costs remains a concern.
