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.

Objective To investigate the protective effect of coenzyme Q10 (CoQ10) in the liver of preeclampsiapregnant rats and the potential etiology. Methods Fifty pregnant SD rats were equally divided into the normal pregnant (NP) group (n=10) and the preeclampsia (PE) group (n=40) randomly. The PE rats (n=40) were equally divided into four groups randomly,distilled water(DW)group,CoQ10 group, CoQ10 combined magnesium(CM) group and magnesium (Mg) group were established by treating the preeclampsia rats on day 15 to 21 of gestation with different measures. As for all the 50 rats, systolic blood pressure (SBP) of rat tail was detected on day 10, 15 and 21 of gestation respectively, 24 hours proteinuria analysis were detected on day 10, 15 and 21 of gestation respectively, levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) in blood andsuperoxide dismutase (SOD), glutathione peroxidase (GSH-PX), malondialdehyde (MDA), caspase-3, Bcl-2 and Bax protein expression in liver tissue were detected by western blot assay on day 21 of gestation. Results (1)SBP and 24 hours proteinuria analysis:there was no statistic difference among all the five groups on day 10 of gestation (P>0.05). Whereas, SBP and 24 hours proteinuria analysis were significantly higher in CoQ10 group, CoQ10 combined CM group, CM group and DW group than that in NP group on day 15, 21 of gestation (P<0.05). And SBP and 24 hours proteinuria analysis were significantly lower in CoQ10 group, CoQ10 combined CM group and CM group than that in DW group on day 21 of gestation (P<0.05). (2) Liver function: among CoQ10 group, CoQ10 combined CM group, CM group, DW group and NP group, serum levels of ALT were respectively(52±7),(34±9),(49±10), (70 ± 19),(30 ± 7)U/L;and serum levels of AST were respectively(169 ± 25),(84 ± 11),(159 ± 20),(281 ± 26)and(78±18)U/L. ALT and AST serum levels were significantly higher in CoQ10 group, CM group and DW group than that in NP group (P<0.05). ALT and AST serum levels were significant lower in CoQ10 combined CM group than those in CoQ10 group, CM group and DW group, respectively (P<0.05). ALT and AST serum levels were significant lower in CoQ10 group and CM group than that in DW group, respectively (P<0.05). (3) SOD, GSH-PX, MDA, caspase-3, Bcl-2 and Bax expression in liver tissue of rats: SOD expression was significant higher in CoQ10 group, CoQ10 combined CM group than thoes in CM group, DW group and NP group(P<0.05);SOD expression was significant lower in CM group, DW grouo than thoes in NP group(P<0.05);and SOD expression was significant higher in CM group than that in DW group(P<0.05). Compared with CoQ10 group, CoQ10 combined CM group, CW group and DW group respectively, the GSH-PX and Bcl-2 protein expressions were significant higher in NP group(P<0.05), while MDA, caspase-3 and Bax protein expressions were significant lower in NP group(P<0.05);compared with CoQ10 group, CoQ10 combined CM group and CW group respectively, the GSH-PX and Bcl-2 protein expressions were significant lower in DW group (P<0.05), while MDA, caspase-3 and Bax protein expressions were significant higher in DW group (P<0.05). Conclusions Oxidative stress and apoptosis levles were upregulated in PE pregnant liver tissues. CoQ10 could effectively protect the liver by improving the liver functions and decreasing the apoptosis of liver cells in PE pregnant rats, and markedly decrease the oxidative stress and apoptosis in the livers. The protective roles of CoQ10 in liver might through its function of anti-oxidative stress and inhibiting cell apoptosis by regulating the balance of Bcl-2/Bax.

Objective To investigate the change of adipocyte fatty acid-binding protein(FABP4) in maternal serum and umbilical cord blood and FABP4 mRNA placental expression in patients with preeclampsia(PE). Methods A total of 60 women with PE and 60 normal pregnant women as control participated in this study. All are admitted to Fujian Maternity and Children Health Hospital for delivery from December 2008 to October 2009. 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). Enzyme-linked immunosorbent assay (ELISA) was used to detect FABP4,fasting serum glucose,fasting insulin(FINS) in maternal serum and FABP4 in umbilical cord blood. Real-time fluorescent quantitative revere transcription PCR was used to detect placental FABP4 mRNA expression. Furthermore,clinical and biochemical parameters were recorded, such as body mass index(BMI), systolic pressure(SP),diastolic pressure (DP), mean arterial pressure (MAP), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), creatinine (Cr), uric acid (UA) , glomerular filtration rate (GFR), 24 hours urine protein in pregnant women and neonatal weight. Results (1) Maternal serum FABP4 was (176 ± 9) ng/L in early-onset PE group and (170 ± 9) ng/L in late-onset PE group, significantly elevated as compared to (81 ± 13) ng/L in early control group and (94 ± 15) ng/L in late control group. (2) Mean maternal FINS, homeostasis model of assessment for insulin resistence index (HOMA-IR) were significantly elevated in the early-onset PE group and late-onset PE group as compared to control groups, respectively. (3) Mean placental FABP4 mRNA expression were significantly elevated in the early-onset PE group and late-onset PE group as compared to late control group. However, no significant difference was found in placental FABP4 mRNA expression between early-onset and late-onset PE groups.(4) Mean umbilical cord blood FABP4 concentrations were significantly decreased in the early-onset PE group and late-onset PE group as compared to late control group. Furthermore, umbilical cord blood FABP4 concentration correlated negatively with maternal serum FABP4 level and placental FABP4 mRNA expression, but positively with neonatal weight. (5) Mean maternal serum FABP4 concentrations correlated positively with placental FABP4 mRNA expression,TG, FINS, HOMA-IR, Cr, UA; and negatively with HDL, GFR. Conclusions Increased FABP4 expression in maternal serum and placenta may be involved in the pathogenesis of preeclampsia. Increased FABP4 mRNA expression in placenta may contribute to high serum FABP4 level in women with PE.

creased maternal serum adiponectin level may be involved in the pathogenesis of pre-eclampsia and also may contribute to the reduced expression of adiponectin in the omental adipose tissue.

Objective To investigate the relationship between the expression level of vascular endothelial growth factor (VEGF) and microvessel density (MVD) in placenta tissue and placenta increta.Methods Thirty singleton pregnant women who received antenatal care and underwent cesarean section in Fujian Maternity and Child Health Hospital between November 2013 and August 2014,were enrolled in this study.They were divided into placenta previa group,placenta increta group and control group,with ten patients in each group.Placenta tissue was collected from each patient.Expressions of VEGF and its mRNA were detected by immunohistochemistry,Western blot,and real-time polymerase chain reaction.MVD in placenta tissue was measured by immunohistochemistry.Rank sum test,t test,Kruskal Wallis test,one-way ANOVA and Spearman correlation test were used for statistical analysis.Results (1) Gestational age at admission and delivery in placenta previa and placenta increta groups was lower than in control group (all P＜0.05).Compared with control group,the placenta previa and placenta increta groups had more blood loss,and longer operating duration and hospital stay (all P＜0.05).(2) The expression levels of VEGF and its mRNA in placenta increta and placenta previa groups were higher than in control group (VEGF:0.691±0.032,0.695 ± 0.027 and 0.518±0.025,respectively,F=373.401;VEGF mRNA:1.667±0.661,1.832±0.678 and 0.767±0.269,respectively,F=27.399;both P＜0.05).But there was no significant difference between placenta previa and increta groups.(3) There was no significant difference of VEGF expression in increta location,border site and normal site in placenta increta group,but its mRNA was decreasing (2.519± 0.116,1.482 ± 0.232 and 1.000± 0.000,respectively,F=240.827,P＜0.05).(4) Expression level of VEGF at the attachment of umbilical cord,upper and lower margin of placenta in placenta previa group was higher than in control group (0.702 ± 0.026 vs 0.528± 0.020,t=12.302;0.698 ± 0.026 vs 0.519±0.035,t=12.715;and 0.685±0.029 vs 0.509±0.010,respectively,t=17.891;all P＜0.05).Expression of VEGF mRNA in placenta previa group was higher than in control group (2.080± 0.539 vs 1.024±0.272,t=8.093;1.587±0.757 vs 0.546±0.083,t=2.401;1.828±0.704 vs 0.731 ±0.157,t=4.259;all P＜0.05).(5) MVD in placenta increta group and placenta previa group was higher than in control group (171.2± 14.7,155.7± 14.6 vs 147.8±12.3,respectively,F=7.277,P＜0.05).(6) Expression level of VEGF in placenta increta group and control group was positively associated with MVD (r=0.825,P＜0.05).Conclusions There may be some common mechanisms in the occurrence of placenta previa and placenta increta.Overexpression of VEGF in placenta and abnormal formation of villous vessels may be important factors in the pathogenesis of placenta increta.

Objective To explore the clinical value of real time contrast-enhanced ultrasound in diagnosis of liver localized fatty deletion and fatty infiltration which couldn't be confirmed by conventional ultrasonography. Methods Contrast-enhanced ultrasound was performed on 94 patients with liver localized diseases confirmed by baseline sonography, among them 34 patients with liver localized fatty deletion and fatty infiltration were enrolled. Results Contrast-enhanced ultrasonography didn't show apparent occupancy nidus in 34 patients. Enhancement mode of lesions was the same as liver parenchyma, which was distinctly different from liver occupancy diseases. Conclusion Real time contrast-enhanced ultrasound can display typical signs of liver localized fatty deletion and fatty infiltration and has significant value in diagnosis and differentiating diagnosis of them.

The nutritional survey was made in 184 anorexia children aged 3-7, 123 of them were treated with various measures for three months. The results indicated that the children with anorexia had low intake and deficiency in energy, protein, minerals and vitamins. Most of them had zinc deficiency, but they simultaneously had two to three nutrients deficiency.The zinc treatment could improve most patient's syndrome and nutritional status. The effect of zinc treatment with vitamines and iron preparations was better than zinc treatment only. The effect of treatment with Chinese medicine also was able to cure the children with anorexia to certain extent.

Objective To explore the mechanisms of individual, social and environmental factors influencing physical activity and the relationships among the factors in patients with type 2 diabetes. Methods A survey was conducted from January to July 2015 among 225 patients with type 2 diabetes using convenience sampling. The questionnaire included 9- item Patient Health Questionnaire, the International Physical Activity Questionnaire,Perceived Social Support Scale, Chinese Walkable Environment Scale, Bandura′s Exercise Self- efficacy Scale. Results The effective questionnaire recovery rate was 98.7%(222/225). Exercise self- efficacy was a mediator of factors influencing physical activity. Exercise self- efficacy and physical activity were positively correlated (β=0.24, P<0.05). Walkable environment only affected physical activity indirectly medicated by exercise self- efficacy (β=-0.26, P<0.05). Perceived social support directly associated with physical activity (β=0.14, P<0.05). Depression not only affected physical activity directly (β=-0.28, P<0.05), but also associated with physical activity indirectly medicated by exercise self-efficacy (β=-0.32, P<0.05). Conclusions Interventions should be taken to increase the perceived social support, improve depression and walkable environment, especially to enhance exercise self- efficacy, so as to improve the physical activity level of patients with type 2 diabetes.
