Objective To discuss the effect and the method of treatment of anti-cardiolipin antibody (ACA),ANA and ENA on abnormal delivery women,and their relationship with abnormal delivery.Methods The concentrations of plasman ACA,ANA,ENA and the times of abortion in abnormal delivery for 193 cases of abnormal delivery women and 100 cases of normal pregnancy were quarnlitatively detected and satistically analyzed.The 81 ACA positive patients were treated orally with aspirin,25 ACA and ANA/ENA positive patients were treated with aspirin combined with prednisone,and 3 ANA/ENA positive patients with prednisone treatment oral.Results The number of ACA and ANA positive patients was closely related to the types of abmormal delivery. The ANA and ENA positive patients was related to the times of abortion. There was no difference in the outcome of treatment between both therapies of aspirine and aspirine combined with prednisone in abnormal delivery women.Conclusions ACA is an important factor in causing abnormal delivery. No matter what ANA and ENA are in ACA positive patients,their can be treated with aspirin alone.

OBJECTIVE:
To investigate the spatiotemporal expression of neuromedin B receptor (NMBR) in mice myometrium at different pregnant stages, as well as its mechanism and relation with parturition.
METHODS:
The pregnant mice were divided into no-pregnancy (NP), early pregnancy (EP), mid-pregnancy (MP), late-pregnancy (LP), parturition (PT) and postpartum (PP) groups (12 mice in each group), according to pregnant stage. The mRNA and protein expression of NMBR, HSP70 and IL-6 were detected in myometrium in pregnant mice by semi-quantitative RT-PCR and Western blot, while NF-kappaB-P65 DNA binding activity was determined by NoShift transcription factor assay kits, respectively. Their relation with parturition was analyzed.
RESULTS:
The mRNA expression level of NMBR in the PT group was significantly higher than that in the NP, EP, LP and PP groups (P<0.05), but this difference was not observed in the MP group (P>0.05). The NMBR protein in PT group was significantly higher than that in the other 5 groups (P<0.01). NF-kappaB-P65 DNA binding activity at PT group was remarkably higher than that in the NP, LP and PP groups (P<0.05). The expression of IL-6 mRNA was significantly higher than that in the NP, LP and PP groups (P<0.05), its protein expression in PT and LP groups was significantly higher than that in the NP and PP groups (P<0.05). The expression of HSP70 mRNA in the PT group was significantly higher than that in the NP and PP groups (P<0.05), and the protein of HSP70 was significantly up-regulated in PT and PP groups compared with in NP and LP groups (P<0.05). The DNA-binding activity of P65 was positively correlated to the mRNA expression of NMBR and IL-6 (r=0.40, P<0.01; r=0.30, P<0.05), so were positively correlated to DNA-binding activity of P65, mRNA expression of HSP70 and NMBR ( r=0.40, P<0.01; r=0.49, P<0.01). DNA-binding activity of P65 did not correlate with the mRNA expression of HSP70.
CONCLUSION
The mRNA and protein expressions of NMBR reach a peak at the onset of labor. NMBR may play an important role in the parturition via NF-kappaB P65-IL-6 signal transduction pathway. It may also influence the onset of labor by regulating HSP70, but this role does not rely on P65 pathway.

OBJECTIVE:
To evaluate the value of selective arterial occlusion in the treatment of placenta percreta in late trimester of pregnancy.
METHODS:
Fifteen clinical patients ( gestational age ≥34 weeks), diagnosed with placenta percreta in Xiangya Hospital of Central South University from January 2003 to December 2010, were retrospectively analyzed. According to whether the selective arterial occlusion was used or not, the 15 patients were divided into 2 groups: an arterial occlusion group (n=8) and a non-arterial occlusion group (n=7). Based on the time of occlusion, the arterial occlusion group was divided into a prophylactic occlusion subgroup (n=4) and a remedial occlusion subgroup (n=4) (including 1 patient who was performed after the iliac artery balloon was taken out ). The blood loss, the rate of hysterectomy and complications were compared between the arterial occlusion group and the non-arterial occlusion group.
RESULTS:
In all 15 patients, the average amount of blood loss was 3813 mL, and the rate of hysterectomy was 73.3% (11/15). The recent complication rate was 20.0% (3/15, including 2 blood coagulation dysfunctions and 1 lower extremity thrombosis), and long-term complication was not found. The average amount of blood loss in the occlusion group was 2512 mL, the hysterectomy rate was 62.5%(5/8); while the average amount of bleeding was 5549 mL and the hysterectomy rate was 85.7% in the non-occlusion group (6/7). There was significant difference between the 2 groups (P<0.05). The average amount of blood loss and the rate of hysterectomy in the prophylactic occlusion subgroup were lower than those in the remedial occlusion subgroup (1350 mL vs 3600 mL, 60.0% vs 66.7%, P<0.05).
CONCLUSION
Patients with placenta percreta in the third trimester of pregnancy may encounter severe postpartum hemorrhage, and the rate of hysterectomy is high. The amount of blood loss and the rate of hysterectomy may be reduced by the selective arterial occlusion before or in the cesarean section, but cannot be avoided completely.
