Proton pump inhibitors are H+ /K+-ATPase inhibitors, which can efficiently inhibit gastric acid secretion for a long time. As the latest inhibitory gastric acid drugs, proton pump inhibitors are the best choices for acid-related diseases such as gastroe-sophageal reflux disease, peptic ulcer and gastrointestinal lesions caused by nonsteroidal anti-inflammatory drugs. Proton pump inhibi-tors have significant inhibition to basal gastric acid, night gastric acid and gastric acid secretion caused by gastrin and food stimulation. This article reviewed the pharmacokinetic characteristics of five proton pump inhibitors in domestic market.

ObjectiveTo study the effects of chemotherapy on growth development and endocrine function of long-survived children with acute lymphoblastic leukemia (ALL). Methods30 ALL patients who were received standard chemotherapy and survived more than five years were enrolled in this study. Their growth and development data and endocrine function examination were investigated. ResultsThrough testing,except two cases of height more than two standard deviation above,the others were all within the normal range; BMI exceeded bid in 1, and the rest were in the normal range;The results of sex hormones examination were consistent with age and Tanner installment, the girls appeared secondary sex characteristics in 9 years old or so,menstruation in 13 years old. Boys appeared sec-ondary sex characteristics around 10 years old;Cortisol and promote adrenal cortical hormone with 2 cases of obese children were in the normal range,but c-peptide and insulin were elevatory;The results of IGF-1 were in the normal range. ConclusionChemotherapy had no significant effect on growth development and endocrine function for patients with ALL.
