Chinese Journal of Pharmacology and Toxicology 2010;24(1):73-76
Erythropoietin(EPO) is a main growth factor that regulates the erythropoiesis under the physiological conditions and after blood loss. At present, it is one of the special effective clinical drugs for treating anemia due to renal failure, chronic infection, AIDS, tumor and some other causes. However, its short plasma half-life makes more frequent administration, which increases the burden and pain on patients. Therefore, development of long-acting agents is a hot. Continuous erythropoietin receptor activator(CERA) is a third-generation erythropoiesis-stimulating agents(ESA). It has a largely prolonged plasma half-life and extended administration intervals, which are different from other ESAs. This review gives a detail demonstration about the development, molecular structure, biochemical characteristics and the most common adverse effects of CERA, as well as the international attention when CERA works as a doping.

Objective To investigate the changes and effects of intercelluar adhesion molecule-1 (ICAM-1) and inhibitor protein of nuclear factor-?B(I?B?) in pulmonary hemorrhage induced by endotoxin lipopolysaccharide (LPS) in neonatal rats. Methods Sixty-eight seven to ten-day-old Wistar rats were separated into 2 groups randomly. In the experimental groups, LPS was injected intraperitoneally at the dosage of 5 mg/kg and the normal saline (NS) control group was injected with equal amount of NS intraperitoneally. The rats were sacrificed at 30 min, 1, 2, 4, 8, 16 and 24 h post injection. The histology of lung tissues were examined by microscope and electron microscope. The expression of ICAM-1, I?B?protein and mRNA expression were observed using Western blot and in situ hybridization. Results One hour after LPS administration, pulmonary hemorrhage and inflammatory responses were observed in the rat lungs. The ICAM-1 protein expression greatly increased at 2 h post injection and it was significantly higher than control group(178.13?8.18 vs 161.57?12.52, P

Objective To observe the impact of hyperbaric oxygen (HBO) therapy on blood pressure and heart rate in adults with spinal cord injury (SCI). Methods 48 adult SCI patients who accepted HBO therapy from March to November, 2014, were observed. Other 48 non-SCI patients matched sexes and ages were as the controls. Their blood pressure and heart rate were measured before chambering, before compression, HBO for 30 minutes, before decompression and at the end of decompression. The patients were divided into high SCI group and low SCI group based on the injury levels above or below T4. Results The blood pressure was lower in the high SCI patients than their controls (t>6.337, P<0.001), and increased as taking in the oxygen. There was no significant difference between the high SCI patients than their controls as they took in for 30 minutes and before the decompression (P>0.05). No difference was found between both groups in heart rate (P>0.05). For the low SCI patients, neither the blood pressure nor the heart rate was different from their controls (P>0.05). Conclusion The blood pressure may increase during HBO intaking in the high SCI patients, which need be paid attention to.
