Construction of a Clinical Prediction Model for Complications After Femoral Head Replacement Surgery.

Background: While femoral head replacement is widely used with remarkable efficacy, the complexity and diversity of postoperative complications pose a serious prognostic challenge. There is an urgent need to develop a clinical prediction model that can integrate multiple factors and accurately predict the risk of postoperative complications to guide clinical practice and optimize patient management strategies. This study is dedicated to constructing a postoperative complication prediction model based on statistics and machine learning techniques, in order to provide patients with a safer and more effective treatment experience.

Vitamin D level and fractures in children and adolescents: a systematic review and meta-analysis.

Introduction: The aim of the study was to determine the relationship between vitamin D levels and the risk of bone fractures in children and adolescents.

Materials And Methods: PubMed, Embase, and Cochrane library databases were searched using subject and free words. The Newcastle-Ottawa scale form was used to assess literature quality.

MAP2K6-FP Enhances the Sensitiveness of Paclitaxel for Ovarian Cancer via Inducing Autophagy.

Background: Paclitaxel is recommended as a first-line chemotherapeutic agent against ovarian cancer, but drug resistance becomes a major limitation. The key molecule or mechanism associated with paclitaxel resistance in ovarian cancer still remains unclear. Recent studies have revealed an association between autophagy and drug resistance.

Delivery of Constitutively Active Mutant MKK6(E) With TAT-OSBP Induces Apoptosis in Human Ovarian Carcinoma HO8910 Cells.

Biologically active peptides and proteins are novel agents that show promise in the development of anticancer drugs. Their relatively low cell permeability and poor tumor selectivity, however, impede their widespread applicability. In this study, we evaluated the tumor selectivity, cellular internalization, and biological activity of a cell-permeable ovarian cancer cell-specific therapeutic protein consisting of TAT-OSBP and constitutively active MKK6(E), an upstream kinase of the p38 signaling pathway that mediates cellular apoptosis.

Mitogen-activated Protein Kinase Kinase 6-fusion Protein (MAP2K6-FP) Potentiates the Anti-tumor effects of Paclitaxel in Ovarian Cancer.

Objective: To investigate the antitumor effects of a mitogen-activated protein kinase (MAPK) kinase fusion protein, TAT-OSBP-MKK6E (MAP2K6-FP), and paclitaxel as single agents and in combination against HO8910 human ovarian cancer cells.

Methods: We previously synthesized a MAPK kinase-recombinant fusion protein, MAP2K6-FP, that contains three domains: a protein transduction domain TAT, a human ovarian cancer HO8910 cell-specific binding peptide (OSBP), and a potential anti-tumor effector domain MKK6 (E). The HO8910 cells were exposed to MAP2K6-FP, paclitaxel, or both for 24 h.
