Chinese Journal of Obstetrics and Gynecology 2012;47(6):412-417
Objective To investigate the relationships between concentrations of free fatty acid (FFA) in maternal serum and oxidative damage levels in placental mitochondria and preeclampsia ( PE)-Methods A total of 60 women with PE and 60 normal pregnant women as control participated in this study.All were admitted to Fujian Maternity and Child Health Hospital for delivery from August 2010 to May 2011.Patients with PE were divided into early-onset group ( n =30,presented at < 34 weeks of gestation ) and late-onset group ( n =30,presented at ≥ 34 weeks of gestation),with 30 normal pregnant women as early control group ( < 34 weeks of gestation ) and 30 as late control group ( ≥34 weeks of gestation).Improved copper agent colorimetry was used to detect FFA in maternal serum Ultraviolet colorimetry was used to detect glutathione peroxidase (GPX) and catalase (CAT) activity in maternal placenta and malondialdebyde (MDA) and permeability transiton (PT) pore in placental mitochondria.Total superoxide dismutase (SOD) assay kit-WST was used to detect SOD activity in placenta.Real-time fluorescent quantitative PCR was used to detect mitochondrial DNA (mtDNA) expression in placenta.Results ( 1 ) Maternal serum FFA was ( 1.6 ±0.5 ) mmol/L in early-onset PE group and ( 1.5 ± 0.4) mmol/L in lateonset PE group,significantly elevated as compared to ( 1.0 ± 0.5 ) mmol/L in early control group and (0.9 ±0.5) mmol/L in late control group (P < 0.05 ). However,no significant difference was found between early-onset and late-onset PE groups (P > 0.05 ).(2) The mean placental GPX,CAT and SOD activity were significantly decreased in the early-onset PE group [ (47 ±6),( 19 ±5),(62 ± 13) U/mg]and late-onset PE group [ (67 ±6),(20 ±4),(96 ± 17) U/mg] as compared to late control group [ (80 ±3),(55 ± 3 ),( 123 ± 19 ) U/mg],respectively ( P < 0.05 ).(3) The mean placental mitochondria MDA was significantly elevated in the early-onset PE group [ (115 ± 22) nmol/mg] and late-onset PE group [(90±17) nmol/mg] as compared to late control group [(52 ± 11) nmol/mg,P <0.05].The mean absorption value that present the permeability of placental mitochondria PT pore was significantly elevated in the early-onset PE group (0.086 ±0.013) and late-onset PE group (0.069 ±0.014) as compared to late control group (0.052 ± 0.0 12,P < 0.05 ).The mean placental mtDNA expression was significantly elevated in the early-onset PE group (3.0 ±0.7) and late-onset PE group (2.8 ±0.7) as compared to late control group ( 2.6 ± 0.6,P < 0.05 ).( 4 ) The mean placental mitochondria MDA concentration correlated positively with the concentrations of FFA in maternal serum in the early-onset PE group ( r =0.703,P <0.05 ) and late-onset PE group (r =0.457,P < 0.05 ),and negatively with placental antioxidant enzyme in the early-onset PE group ( r =- 0.652,- 0.787,- 0.952 ; P < 0.05 ) and late-onset PE group ( r =-0.378,-0.689,-0.854; P<0.05).Conclusions Increased FFA in maternal serum and high levels of oxidative damage in placental mitochondria may be involved in the pathogenesis of preeclampsia.Increased FFA in serum and decreased activity of antioxidant enzyme in placenta may contribute to oxidative damage levels in placental mitochondria in women with PE.

Chinese Journal of Medical Imaging 2013;(6):428-430
Purpose To evaluate the application value of rapid exchange method in transnasal intestinal obstruction catheterization. Materials and Methods Fifty-eight patients with adhesive intestinal obstruction underwent transnasal catheterization under X-ray fluoroscopy, of which 31 cases were treated with rapid exchange catheterization method (group A) and the other 27 cases with traditional catheterization method (group B), success rate, operation time and complications were compared between the two groups. Results Catheterization success rate of group A and group B were 96.77%(30/31) and 77.78%(21/27) respectively, which was significantly higher in group A than in group B (χ2=4.907, P<0.05);operation time of group A and group B were (28.2±12.3) min and (25.4±15.7) min respectively, and the difference between them was not statistically significant (t=1.219, P>0.05); no operation associated injury occurred in group A and only one case in group B (3.70%) resulted in bilateral nasal edema with a small amount of bleeding because the operating time was too long, complication rate between the two groups was also not statistically significant (P>0.05). Conclusion Rapid exchange method can improve the success rate of transnasal intestinal obstruction catheterization, but the operation time and complications are comparative to those of the conventional method.
