RESUMO
Background: Total hip arthroplasty (THA) has emerged as a pivotal approach for addressing femoral neck fractures (FNFs), a prevalent type of fracture in older people. Restoring joint functionality following surgery significantly contributes to patients' overall well-being. Therefore, the implementation of rational and effective rehabilitation exercises is crucial. Objective: This study aims to investigate the impact of phased rehabilitation management on patients with FNFs who have undergone THA. Methods: In this prospective comparative study, a total of 89 patients were enrolled. Among them, 49 patients underwent phased rehabilitation management, while 40 patients received conventional postoperative rehabilitation. The evaluation encompassed a range of assessments, including the Harris Hip Score (HHS) for the evaluation of hip joint function, the Five-Times-Sit-to-Stand Test (FTSST) to quantify lower limb muscle strength, the Barthel Index to assess activities of daily living, and the Visual Analog Scale (VAS) to measure pain intensity. Furthermore, preoperative and postoperative serum levels of interleukin-6 (IL-6), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were diligently measured to provide a comprehensive understanding of the patient's inflammatory responses. Results: Overall, the study group exhibited a significantly higher average HHS after surgery compared to the control group. Notably, the VAS scores at 1 day and 3 days post-surgery in both groups demonstrated a reduced trend compared to preoperative values. This trend was more significant in the study group compared to the control group. The time taken for the FTSST in patients undergoing phased rehabilitation management was less compared to the control group. Furthermore, phased rehabilitation management was associated with more significant improvements in activities of daily living. Notably, IL-6 levels were higher in both the study and control groups at 1 day postoperatively than before surgery, while they decreased at 3 days postoperatively compared to the 1-day mark. The study group exhibited significantly lower levels of CRP (mg/L) and ESR (mm/h) compared to the control group. Conclusions: Implementing phased rehabilitation management for patients with FNFs following THA improves hip joint function, lower limb muscle strength, daily living activities, pain intensity, and inflammatory response.

In this study, we described a series of 2,8-diazaspiro[4.5]decan-1-one derivatives as selective TYK2/JAK1 inhibitors. Systematic exploration of the structure-activity relationship through the introduction of spirocyclic scaffolds based on the reported selective TYK2 inhibitor 14l led to the discovery of the superior derivative compound 48. Compound 48 showed excellent potency on TYK2/JAK1 kinases with IC50 values of 6 and 37 nM, respectively, and exhibited more than 23-fold selectivity for JAK2. Compound 48 also demonstrated excellent metabolic stability and more potent anti-inflammatory efficacy than tofacitinib in acute ulcerative colitis models. Moreover, the excellent anti-inflammatory effect of compound 48 was mediated by regulating the expression of related TYK2/JAK1-regulated genes, as well as the formation of Th1, Th2, and Th17 cells. Taken together, these findings suggest that compound 48 is a selective dual TYK2/JAK inhibitor, deserving to be developed as a clinical candidate.
