摘　　要：Background： Pravastatin （Pra） exerts protective effects on preeclampsia. Preeclampsia is a multifactorial and pathogenic pathway syndrome. The present study compared the effects of Pra on clinical manifestations of preeclampsia in different pathogenic pathways. Methods： Two different preeclampsia-like mouse models used in this study were generated with Nω-nitro-L-arginine methyl ester （L-NAME） and used lipopolysaccharide （LPS） from day 7 of gestation, respectively. Pra treatment was administered on day 2 after the models were established in each group （L-NAME ＋ Pra, LPS ＋ Pra, and Control ＋ Pra, n = 8） or normal saline （NS） for the control group （L-NAME ＋ NS, LPS ＋ NS, and Control ＋ NS, n = 8）. Maternal weight, serum lipids, the histopathological changes, and lipid deposition in the liver and placenta were observed. The pregnancy outcomes were compared. The blood pressure analysis was carried out on repeated measurements of variance. Student＇s t-test was used for comparing the two groups. The enumeration data were compared by Chi-square test. Results： The mean arterial pressure （MAP） and 24-h urinary protein in the L-NAME ＋ NS and LPS ＋ NS groups were significantly higher than the Control ＋ NS group （F = 211.05 and 309.92 for MAP, t = 6.63 and 8.63 for 24-h urinary protein; all P 〈 0.05） and reduced in the L-NAME ＋ Pra group as compared to the L-NAME ＋ NS group （F = 208.60 for MAP, t = 6.77 for urinary protein; both P 〈 0.05）. Urinary protein was decreased in the LPS ＋ Pra group as compared to the LPS ＋ NS group （t = 5.33; P 〈 0.05）, whereas MAP had no statistical significance （F = 3.37; P 〉 0.05）. Compared to the Control ＋ NS group, the placental efficiency in the L-NAME ＋ NS and LPS ＋ NS groups decreased significantly （t = 3.09 and 2.89, respectively; both P 〈 0.05）; however, no significant difference was observed in L-NAME ＋ Pra and LPS ＋ Pra groups （t = 1.37 and 0.58, respectively; both P 〉 0.05）.
