A 32-year-old female patient with nephrotic syndrome got pregnant during treatments with losartan potassium tablets (50 mg once daily), methylprednisolone tablets(12 mg every other day), and dipyridamole tablets(50 mg once daily). She continued these drugs during pregnancy. Ultrasonographic examination at 24 +2 weeks of gestation indicated oligohydramnios, which lasted until 32 +2 weeks of gestation. The amniotic fluid volume ranged 1.1-3.4 cm, and the amniotic fluid indexes were 1.9-6.9 cm. Losartan and methylprednisolone were discontinued, and nifedipine controlled released tablets (30 mg once daily) were given to reduce blood pressure. Amniotic fluid volume gradually increased to normal. At 34 +4 weeks of gestation, her blood pressure rose to 177/113 mmHg. Preeclampsia was diagnosed. She was treated with magnesium sulfate (IV infusion at a speed of 1 g/h), oral nifedipine controlled released tablets (60 mg once daily) and labetalol (200 mg twice daily). Then her blood pressure was 143/82 mmHg and urinary protein detection was positive (++). At 35 +3 weeks of gestation, a baby boy was delivered by cesarean section, with a body length of 43 cm and a weight of 2 200 g. Neonatal Apgar scores at 1 min and 5 min were both 10, and no birth defects were found. During the follow-up to 24 months of age, his growth and development were good, and intellectual development and physical exercise were normal.

A comprehensive evaluation on textbooks depends not only on experts' opinions but also on the first-hand feedback information from users.This research,based on the Evaluation Norm System issued by Education Department and the real situation of users(students),has set up an evaluation norm system by students for college textbooks.Through the test of this system,it is thought that it can reflect a basic picture of textbooks and is easy to be operated.
