ABSTRACT
Objective To investigate whether the effect of rabeprazole in treating gastroesophageal reflux disease is related to CYP2C19 gene polymorphisms.Methods 278 patients with gastroesophageal reflux disease confirmed by endoscopy and proton-pump inhibitor testing were enrolled in this study,including non erosive reflux disease (NERD) in 122 cases,the reflux esophagitis (RE) in 98 cases and Barrett esophagus in 58 cases.They were treated with rabeprazole for 8 weeks.GerdQ scores before and after the treatment were completed,endoscopy was performed again in patients with RE after treatment.The blood CYP2C19 genotyping was detected by matrix assisted laser desorption ionization time of flight mass spectrum(MALDI-TOF-MS).Results According to the genotype of CYP2C19,they were divided into extensive metabolizers,intermediate metabolizers and poor metabolizers,accounted for 39.57%,42.45% and 17.98%,respectively.There was no significant difference in GerdQ scores of three groups before treatment,and also had no significant difference after 8 weeks treatment,but in each subgroup GerdQ scores after treatment was decreased significantly than before treatment.The total effective rate of 98 patients with RE by endoscopy was 86.73%,but there was no significant difference in total effective rate of the three groups after treatment.Conclusion Rabeprazole is effective in the treatment of gastroesophageal reflux disease.Moreover,rabeprazole is less affected by CYP2C19 genotype and therefore its curative effect is more stable.
ABSTRACT
Objective To investigate the early diagnosis and disease evaluation value in patients with acute pancreatitis by various serum cytokines measurement.Methods Forty-eight acute pancreatitis patients were divided into two groups based on the results of computed tomography (CT) examination:mild acute pancreatitis group (30 cases) and severe acute pancreatitis group (18 cases).The other 30 normal persons were selected as control group.The various serum cytokines were measured by enzyme-linked immunosorbent assay (ELISA).Results The serum concentrations of interleukin(IL)-1,IL-10 and tumor necrosis factor (TNF)-α in mild acute pancreatitis group were significantly higher than those in control group [(25.00 ± 1.92) ng/L vs.(10.08 ± 2.65) ng/L,(59.78 ± 4.51) ng/L vs.(1.80 ± 0.66) ng/L,(55.31 ± 8.54) ng/L vs.(18.72 ± 7.84) ng/L,P ＜ 0.05].The serum concentrations of IL-1,IL-6,IL-8,TNF-α and platelet activating factor (PAF) in severe acute pancreatitis group were significantly higher than those in mild acute pancreatitis group [(93.27 ± 3.98) ng/L vs.(25.00 ± 1.92) ng/L,(397.84 ± 13.05) ng/L vs.(34.12 ± 4.96) ng/L,(93.32 ±3.40) ng/Lvs.(13.06± 1.86) ng/L,(181.94 ±7.54) ng/Lvs.(55.31 ±8.54) ng/L,(284.53 ±7.88) ng/L vs.(175.25 ±30.15) ng/L,P＜0.05].Conclusion The various serum cytokines measurement has great importance on the early diagnosis of acute pancreatitis and discrimination between the mild acute pancreatitis and severe acute pancreatitis.
