ABSTRACT

Objective To investigate the expression of serum amyloid A (SAA) in patients adipose tissue with gestational diabetes mellitus (GDM) and the correlations between SAA and insulin resistance (IR) and body mass index (BMI).Methods A total of 60 single full-term pregnant women underwent cesarean section from June 2013 to December 2013 was enrolled in this study (GDM group,n =30;control group,n =30);serum SAA level was detected with Enzyme-Linked Immunosorbent Assay (ELISA);and mRNA expression of SAA1 in adipose tissue was determined by reverse transcription PCR (RT-PCR);SPSS software was used to compare these markers,and the correlations between SAA and HOMA-IR,BMI were analyzed with Pearson correlation method.Results SAA,mRNA expressions in omental and subcutaneous fat in GDM group (0.447 ± 0.069,0.291 ± 0.067) were significantly higher than those in control group (0.194 ± 0.070,0.231 ± 0.068,P < 0.01).Serum SAA levels [(21.038 ± 6.648) mg/L] and homeostasis model assessment of insulin resistance(HOMA-IR) (4.168± 2.416) in GDM group were significantly higher than those in control group [(14.384 ± 12.770) mg/L,2.045 ± 1.008,P < 0.05];SAA1 mRNA expression levels in omental and subcutaneous fat were positively correlated with serum SAA (r =0.353,0.342,P < 0.01).SAA1 mRNA expression levels in omental were positively correlated to pregestational BMI,late gestational BMI,weight gain in pregnancy and HOMA-IR (r =0.543,0.644,0.340,0.473,P < 0.01),and SAA1 mRNA expression levels in subcutaneous fat were positively correlated to pregestational BMI,late gestational BMI,and HOMA-IR (r =0.788,0.693,0.504,P < 0.01),but was no correlation with weight gain in pregnancy(r =0.013,P > 0.05).Conclusions SAA mRNA expressions in omental and subcutaneous fat in GDM group and serum SAA levels increase,which is positively correlated with BMI and the degree of insulin resistance,SAA may participate in the formation of GDM by increasing insulin resistance.SAA may be used as a new monitor of GDM.

ABSTRACT

Objective To analyze the cause and clinical characteristics of maternal cardiac arrest.Methods The data of all cases of maternal cardiac arrest from January 2005 to December 2009 in Third Affiliated Hospital of Guangzhou Medical College was retrospectively studied.Results ( 1 ) A total of 41 maternal cardiac arrests (6 in prenatal period,2 in the first stage of labor,7 in the third stage of labor,26 in postpartum period ) were included.All patients regained spontaneous circulation after basic life support.Twelve (29%) mothers survived.Twelve cardiac arrests occurred in the hospital,and the totaldelivery number from January 2005 to December 2009 was 17101,with occurrence rate of 1:1425.(2) Thecauses of arrest were hemorrhagic shock (12,29%),amniotic fluid embolism (7,17%),severepreeclampsia/eclampsia (7,17%),septic shock (6,15%),cardiac disease (2,5%),unidentified cause (2,5% ) and other occasional causes.(3) Thirty-seven (90%) in-hospital maternal cardiac arrest occurred in operation room (16,39% ),ICU (7,17% ),maternity wards (6,15% ),delivery room (5,12% ) and the emergency room (3,7% ).Three (7%) arrest occurred out of hospital and one in the ambulance.Matemal survival rate was 2/3 in the emergency room,8/16 in the operation room,1/5 in the maternity wards,and 1/6 in the delivery room.No mother survived in ICU,ambulance or out of hospital.(4) Five of the 12 survived women showed ischemic encephalopathy after cardiac arrest and one of them developed cerebral infarction in the right corona radiate.(5) In 4 of the 8 cases of cardiac arrest in pregnancy,perimortem caesarean section (PMCS) was performed.In the four PMCS,2 mothers and 2 children survived.In the 4 cases that PMCS was not carried out,no infant survived.Conclusions Hemorrhagic shock,severe preeclampsia and eclampsia,amniotic fluid embolism are the major obstetric causes of maternal cardiac arrest.Septic shock and cardiac diseases are the major non-obstetric causes.Cardiac arrests occurred in emergency room and operation room has a higher maternal survival rate than those occurred in the delivery room and maternity wards.Timely PMCS may ensure the optimal outcome for mothers and fetuses.

ABSTRACT

Objective To analyse the causes and clinical characteristics of re-exploration after peripartum hysterectomy due to postpartum hemorrhage. Methods Clinical data was analysed retrospectively including 88 critically ill obstetric patients who underwent peripartum hysterectomy due to postpartum hemorrhage in the Obstetric Critical Care Center of Guangzhou from January 1999 to July 2009, which were divided into re-explored group (n= 14) and non-re-explored group (n=74)depending on whether the patient underwent re-exploration after peripartum hysterectomy. The main demographic data and clinical details were compared between the two groups, including mode of delivery, indication and type of hysterectomy, interval from hysterectomy to re-exploration, surgical intervention, complications, blood loss, blood transfusion,Glasgow Coma Score(GCS), the need for mechanical ventilation, intensive care unit stay and hospital stay. Results Fourteen out of the 88 (15.91%) patients underwent re-exploration due to internal bleeding after peripartum hysterectomy.Removal of cervical stump was performed in five patients and stump hemostasis in eight cases.Significant difference was found between the re-exploration and non-re-explored group on thepercentage of patients complicated with disseminated intravascular coagulation(92.9% vs 43.2%,x2=11.598,P=0.001) and amniotic fluid embolism (28.6% vs 2.7%, x2 =8.663, P=0.003).0.000], blood transfusion [(8163.6± 3903.1 ) ml vs (2958.8± 2323.0) ml, P = 0.000], intensive care unit admission rate (100.0% vs 41.9%, x2 = 15.909, P= 0.000), the need for mechanical ventilation (100.0% vs 24.3%,P=0.000), the number of patients with GCS≤8 score (71.4% vs 25.7% ,x2 = 9.179, P = 0.002 ), the number of multiple organ dysfunction syndrome ( 71.4% vs 14.9%, x2 = 17.735, P = 0.000), intensive care unit stay [ ( 11.4 ± 10.0 ) d vs ( 1.3 ± 2.3 ) d, P =0.000] and hospital stay[(24.0±13.1) d vs (12.7±7.0) d, P=0.000]. Allof the 14 cases were clinical recovered before discharge. Conclusions The rate of re-exploration after peripartum hysterectomy is not low, and internal bleeding is the most common causes. The re-exploration after peripartum hysterectomy might be associated with coagulopathy and the mode of hysterectomy, and patients may experience more severe complications.
