Objective To evaluate the effect of spinal-epidural and epidural anesthesia for pain relief in labor. Methods Totally 6671 cases selected from pregnant women delivered from Aug. 2001 to Oct. 2004 in our hospital were reviewed retrospectively. All cases were divided into three groups,1482 cases in spinal-epidural group (combined epidural) and 1111 in epidural group (epidural) who received pain relief during labor; 4078 as control group without any pain relief during labor. Delivery method and maternal, fetal complications among three groups were compared. Results (1) Delivery methods were significantly different (P0.05) in postpartum hemorrhage and neonatal asphyxia between spinal epidural 4.3%(63/1482) 1.0%(15/1482), epidural 4.1%(45/1111),0.8%(9/1111), and control 3.9%(159/4078), 1.4%(56/4078). Conclusions Anesthetic pain relief in labor may reduce the CS rate, but increase the rate of forceps delivery. Pain relief is associated with arrested and prolonged active phase, prolonged second stage. However, pain relief in labor doesnot enhance the rate of postpartum hemorrhage and neonatal asphyxia.

Objective:To compare the difference of serum levels of M-phospholipaseA2 receptor ( PLA2R) antibodies in patients with idiopathic membranous nephropathy(IMN) detected by two different methods and evaluate the diagnostic value of two methods. Methods:Patients diagnosed as membranous nephropathy and other diseases with biopsy-proven from december 2014 to october 2015 in Shengjing Hospital of China Medical University were enrolled and devided into IMN group and non-IMN group. The serum levels of anti-PLA2R antibody were detected by both indirect immunofluorescence assay(IFA) and enzyme linked immunosorbent assay(ELISA). Results:The sensitivity of IFA and ELISA in IMN were 71. 3% and 68. 5%,and the specificities of two methods were the same as 100%. The area under ROC curves of anti-PLA2R antibody for IMN diagnosis were 0. 860 and 0. 839. The diagnostic value of IFA and ELISA was no statistically significant differences in IMN ( P>0. 05 ) , and the consistency of two methods was better (κ=0. 876). The IMN patients of positive anti-PLA2R antibody be susceptible to the low level of serum albumin (P<0. 05). The higher levels of PLA2R antibody were linked with the worse hypoproteinemia and the higher rate of nephrotic-range proteinuria in IMN patients. Conclusion:Two methods of detecting sera PLA2R antibody have higher sensitivity and specificity,so the sera anti-PLA2R antibody was a better biomarker in the diagnosis of idiopathic membranous nephropathy.
