Background And Objective: It ha been proven that serum vascular endothelial growth factor (VEGF) concentration was elevated significantly after surgery in patients of non-small cell lung cancer (NSCLC). Platelet may be the main resource of serum VEGF. The aim of this study is to investigate the correlation between postoperative dynamic changes of serum VEGF levels and platelet counts in patients of NSCLC who underwent surgery.
Methods: Serum VEGF levels were determined in 76 patients of NSCLC who were treated with surgery by ELISA (enzyme linked immunosorbent assay) method before operation and on postoperative day 1, 7. At the same day the concentrations of platelet were determined. RESULTS (1) Serum VEGF in patients of NSCLC on preoperative day, postoperative 1 day and 7 day were (842.06 +/- 527.24) pg/mL, (1 119.28 +/- 609.62) pg/mL, (1 574.09 +/- 873.38) pg/mL, respectively (P < 0.001); (2) Platelet counts in patients of NSCLC on preoperative day, postoperative 1 day and 7 day were (230.42 +/- 82.56 x 10(9)/L, (196.47 +/- 81.48) x 10(9)/L, (237.90 +/- 86.94) x 10(9)/L; the value on postoperative 1 day was the lowest (P < 0.001); (3) On postoperative 7 day, serum VEGF in the group of lower than the mean and higher than the mean were respectively (1 398.81 +/- 734.00) pg/mL and (1 842.86 +/- 1 006.63) pg/mL (P = 0.043).
Conclusion: Serum VEGF in patients of NSCLC after surgery were elevated. In the group of higher platelet counts, serum VEGF increased more significantly.

Background: The upregulation or delay of acute inflammation at any stage limits fat graft survival. Active endogenous inflammation resolution mechanisms and mediators are novel therapeutic tools for inflammation. This study explored the effects of supplementation of omega-3 polyunsaturated fatty acids (PUFAs) deriving specialized proresolving mediators (SPMs) on postoperative inflammation and graft survival in vivo.

Tripterygium wilfordii (TW), which has severe hepatotoxicity, is commonly used as anti-rheumatism. Using the juice of auxiliary herbs in concocting poisonous herbs is a conventional method for toxicity reduction or efficacy enhancement. Traditional Chinese Pharmacy textbooks record that Spatholobi Caulis (SC) can alleviate the side effects caused by TW and also possesses excellent hepatoprotective effect.

Background: Hypoxia-inducible factor 1 alpha (HIF-1α) and its related vascular endothelial growth factor (VEGF) may play a significant role in atherosclerosis and their targeting is a strategic approach that may affect multiple pathways influencing disease progression. This study aimed to perform a systematic review to reveal current evidence on the role of HIF-1α and VEGF immunophenotypes with other prognostic markers as potential biomarkers of atherosclerosis prognosis and treatment efficacy.
Methods: We performed a systematic review of the current literature to explore the role of HIF-1α and VEGF protein expression along with the relation to the prognosis and therapeutic strategies of atherosclerosis.

Limb lengthening and deformity correction techniques, particularly distraction osteogenesis, have significantly evolved in pediatric orthopedics. This study examines the temporal changes of key biochemical markers-vascular endothelial growth factor (VEGF), fibroblast growth factor 1 (FGF-1), and the propeptide of type I collagen (P1NP)-during the limb lengthening process. Twenty pediatric patients (aged 13-16) underwent distraction osteogenesis using the Circular Hexapod External Fixator.

Fetal bovine serum (FBS) has long been the standard supplement in cell culture media, providing essential growth factors and proteins that support cell growth and differentiation. However, ethical concerns and rising costs associated with FBS have driven researchers to explore alternatives, particularly human platelet lysate (HPL). Among these alternatives, fibrinogen-depleted HPL (FD-HPL) has gained attention due to its reduced thrombogenicity, which minimizes the risk of clot formation in cell cultures and enhances the safety of therapeutic applications.
