Objective To explore clinical features of severe preeclampsia patients with adverse outcome, and the risk factors of adverse outcomes. Methods From Jan. 2008 to Dec. 2009 149 severepreeclampsia impatients who occurred adverse outcome enrolled as case,and 278 severe preeclampsia impatientswithout adverse outcome at the same period enrolled as control. The clinical features between the two groups were compared and the risk factors were investigated. Results No significant differences were found between the two groups in maternal age,times of previous prenancies. The gestation ages at the onset of preeclampsia and at delivery in the cases were less than controls(P < 0. 05). There was significant difference in irregular antenatal checks between the two groups(x2 = 8. 515, P < 0. 05). Proterinuria and the level of oedema in cases were higher than controls( P < 0. 05). Fetal growth restriction (FGR) occurred more frequently in the cases (P <0. 05). Indirect bilirubin, total bilirubin, glutamic oxalacetic transaminase, glutamic pyruvic transaminase, uric acid, creatinine, white blood cell, thrombin time, D-dimeride of cases were higher than those of controls(Ps <0. 05). Albumin, platelet and profibrin of cases were lower than those of controls(Ps < 0. 05 =. Multivariate logistic analysis showed that the gestation ages at the onset of preeclampsia, regular antenatal checks were significantly associated with adverse outcome(OR = 0. 899, P < 0. 001; OR = 0. 600, P = 0. 022, respectively =Indirect bilirubin and D-dimeride were significantly associated with preeclampsia complications(OR = 1. 533,P =0. 010; OR = 1.001, P = 0. 003, respectively). Mean arterial pressure and creatinine were significantly associated with eyeground changes(respectively OR = 1. 030,P = 0. 048; OR = 1. 025, P = 0. 022, respectively).Regular antenatal checks was associated with dead fetus(OR = 0. 317, P = 0. 046). No significant differenceswere found between the two group in uterine-incision delivery(P > 0. 05). Incidence rate of low birth weight infants and postpartum hemorrhage of cases were higher than controls and Apgar score was lower in cases than controls( all P <0. 05=. Conclusion The gestation ages at the onset of preeclampsia,regular antenatal checks,fetal distress were risk factors for preeclampsia adverse outcome. Patients with.high indirect bilirubin and Ddimeride are more likely to suffer adverse pregnancy outcomes.

Objective To evaluate the renal function response to vasopressin in obstructed and non-obstructed kidney in vasopressin-deficient rats by using dynamic enhanced MRI. Methods This study included 26 vasopressin-deficient Brattleboro(BB)rats.Unilateral ureteral obstruction(UUO) model was set up in 12 BB rats.After releasing UU0 24 h,treatment of AVP was given in 7 non-obstrueted and 7 obstructed BB rats for 6 d.Seyen normal Wistar rats and 7 BB rats were used as control.Dynamic enhanced MRl was performed at 0-60 min following the administration of GadoliniumDTPA(0.05 mmol/kg)and the mean relative signal intensity(RSI)was measured. Results BB rats RSI increase occurred during the first minute,with a maximum mean RSI of(149±10)%in cortex,(155±13)%in medulla and(146±13)%in pelvis.Then,a gradual decrease in the cortical RSI occurred,after which a small increase was observed in Phase 3.BB rats RSI patterns were different from Wistar rats.After AVP treatment,mean RSI of BB rats in cortex,medulla and pelvis reached a maximum of(180±6)%,respectively at 30 sec,followed by a fast decrease at 1 min.Then,RSI decreased gradually.Phase 3 demonstrated a moderate increase in medullary and a relative large increase in pelvic RSI until 30 min after injection,after which RSI returned to baseline.BB rats RSI patterns after AVP treatment were similar to that of Wistar rats.Cortical,medullary and pelvic mean RSI increased slowly compared to non UUO rats.In phase 3,mean RSI of all segments decreased gradually.UUO rats RSI patterns were different from non UUO rats.After AVP treatment in UUO rats,mean RSIs of all segments increased faster compared to UUO rats without AVP.Cortical mean RSI reached a maximum of(193±7)% at 2 mim Mean RSI of medulla were unchanged,but the pelvic mean RSI deereased gradually to a minimum of(77±5)%at 5 min.Phase 3 was characterized by a slight recovcry of all RSIs.UUO rats RSIs were recovered after AVP treatment.The renal blood flow(RBF)of UUO rats was decreased to(1.1±0.1)m1·min-1·100g-1,wherease the RBF was increased to (1.9±O.3)ml·min-1·100g-1 after injecting AVP. Conclusion Dynamic enhanced MRI may provide useful information for distinguishing between kidneys having changes in the renal vasopressin concentration and the kidneys suffer from the obstructed renal damage.
