研究问题
Pulmonary hypertension (PH) is a complex medical condition involving multiple clinical entities, frequently associated with various cardiovascular and respiratory diseases.
方法
This study was approved by the Local Ethics Committee of Animal Experiments at İnönü University (Approval No.；Fifty-eight male Wistar Albino rats, 3 months old and weighing an average of 300 g, were used in our study.；The animals were obtained from the Laboratory Animal Production and Research Center at İnönü University.；All rats were naive animals with no prior experimental procedures and had a healthy immune status.
核心结论
Direct comparison of the α-LA + AMB group against each monotherapy showed a significantly higher PAT than α-LA alone (p < 0.05), but no significant difference from AMB; RV/LV diameter ratio and TAPSE did not differ significantly between α-LA + AMB and either monotherapy.；Kruskal–Wallis H test, followed by Conover’s post hoc test with Holm correction, was used in the statistical analyses. a: Difference vs. control group (p < 0.05), b: Difference vs.；MCT group (p < 0.05), c: Difference vs. α-LA group (p < 0.05). ‖ 结论：Overall, our results demonstrate that α-LA and AMB exert beneficial effects on pulmonary hemodynamics, RV function, vascular proliferation, and inflammatory processes in experimental PAH, whereas a significant reduction in RV hypertrophy (Fulton index) was observed only with α-LA monotherapy.
局限
These findings should therefore be interpreted with caution when considering their translational relevance to human PAH.；An additional limitation is that biochemical signaling changes (p-AMPK, p-mTOR, NF-κB) were quantified by ELISA alone, without orthogonal validation by Western blotting for p-AMPK/AMPK and p-mTOR/mTOR ratios normalized to a loading control (e.g., β-actin or GAPDH).；Although the ELISA kits used have established specificity and low intra-/inter-assay variability (Section 2.6), Western blot validation would provide complementary confirmation of these findings and is recommended for future work.

本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
