Preparation of bioactive nano-hydroxyapatite coating for artificial cornea
Run-Rong Lin,Xuan Mao,Qi-Cong Yu,Bai-Hua Tan 한국물리학회 2007 Current Applied Physics Vol.7 No.s1
Bioactive coatings containing hydroxyapatite(HA) nano crystals were prepared on PHEMA membrane by a sol dipping method.A cellcoating and the aggregation degree of HA particles inuence the adhesion of the cornea broblasts to the membrane, which dependsdramatically on the weight ratio between the nano-HA and the dispersant. The optimal condition of the coating preparation is with adispersant/HA = 1.25 weight ratio. The PHEMA membrane covered with nano-HA coating is promising for articial cornea use.

Background: Neutrophil to lymphocyte ratio (NLR) in peripheral blood is established to correlate with the morbidity and mortality of heart disease patients. We aimed to define the severity of inflammation (NLR) by observing the association of NLR with cardiac functions or myocardial damage parameters in patients with acute myocardial infarction. Methods: Data from 715 patients who underwent percutaneous coronary intervention (PCI) within 72 hours of incidence in 2016 were analysed retrospectively. Results: The NLR ranges from 0.50 to 46 (medium ± SD, 2.76 ± 2.96) in 715 patients. NLR positively correlated with myocardial damage (NLR vs. CK-mB: p < 0.0001) but negatively correlated with myocardial function (NLR vs. EF: p < 0.0001; NLR vs. FS: p < 0.0001). Myocardial damage markers (CK, CK-mB, ASL, LDH) were significantly increased, and cardiac contractile parameters (EF and FS) were reduced at NLR > 2.76 compared to those of NLR < 2.76. ELISA analysis has shown that IL-10 was significantly increased when NLR ≥ 4.6 and TGF-β was increased at NLR > 4. The correlation was diminished between NLR and CK-mB at NLR > 2.76 or at NLR > 4, but that of NLR and EF or FS was maintained in NLR > 2.76 and at NLR > 4. EF and FS were comparable between NLR > 2.76 and NLR > 4. But myocardial damage parameters increased significantly at NLR > 4 compared to those of NLR > 2.76. Conclusion: NLR is a strong predictor of myocardial damage in acute myocardial patients. High NLR are associated with myocardial dysfunction in all the patients. Severe inflammation (NLR) can predict the consequence of the heart in patients with coronary syndrome.
