RESUMEN
BACKGROUND: Osteoarthritis (OA) is a chronic degenerative disorder probably affected by both genetic and environmental causes. Bone morphogenetic proteins (BMPs) are bone-derived factors that can induce new bone formation. Single-nucleotide polymorphisms (SNPs) of BMP5 gene alters the transcriptional activity of the BMP5 promoter that has been involved in OA susceptibility. This case-control study investigated the association of rs1470527 and rs9382564 SNP of BMP5 gene with susceptibility to knee OA (KOA). MATERIALS AND METHODS: A total of 499 cases with radiographic KOA and 458 age- and sex-matched healthy controls were enrolled. Venous blood samples were obtained from all the cases as well as controls for polymerase chain reaction-restriction fragment length polymorphism. RESULTS: The genotype distribution for rs1470527 and rs9382564 SNP was significantly different in cases and controls (P < 0.0001). Within both the SNPs of BMP5 gene, genotype CT and TT were significantly (P < 0.0001) associated with KOA as compared to the CC genotype. T allele of both the studied SNP was significantly associated with KOA (P < 0.0001). The allele frequencies of rs1470527 were 0.56(T) and 0.44(C) in cases and 0.33(T) and 0.67(C) in controls and in rs9382564 were 0.57(C) and 0.43(T) in cases and 0.71(C) and 0.29(T) in controls. Further in relation with clinical severity of OA, we observed signification association of TT genotype with both visual analog scale (P < 0.0001) and Western Ontario and McMaster Universities score (P < 0.05). CONCLUSION: Our results indicate significant association of rs1470527 and rs9382564 polymorphism of BMP5 gene with KOA.

Rentgenoendovascular embolization of bronchial arteries was performed in 222 patients about pulmonary hemorrhage (PH) of different nature. Resistant hemostasis was achieved in 198 (89.9%) patients. The possibility of endovascular hemostasis in patients in advanced lung cancer complicated by PH. Hemostasis was ineffective in 24 (10.8%) patients. Died 5 (2.2%) patients due to unresectable lung cancer. The reasons for ineffective hemostasis were analysed.

Various methods of radiofrequency ablation, using FOTEK-150 apparatus, were applied in 74 patients for pulmonary and pleural malignancies. Immediate positive effect was achieved in 92% observations, complications have occurred in 13% patients. It is expedient to use the method in patients, suffering pulmonary and pleural malignancies, when radical surgery is impossible. Radiofrequency ablation may be applied as a palliative method of treatment of pulmonary and pleural malignancies.
