Objective To explore clinical features and pregnancy outcomes of early-ouset severe pre-eclampsia. Methods Clinical data of 96 cases of severe preeclampsia who deliveried in Southeast University from November 2004 to February 2009 were analyzed. The patients were divided into two groups, early-onset preeclampsia group(onset gestatioual weeks <34) and later-onset preeclampsia group(onset gestatianal weeks≥34 ). Resnits Significant difference of two groups were found in central nervous system symptom and urine protein (+ +) or > 2 g/24 h (P<0.05), incidence of abnormal prenatal outcome (χ~2=14.792,4.741,27.03 respectively;P<0.05). Mean birth weight in early-onset preeclampsia group (1743.86±630.34)g was lower than that in later-onset pre-eclampsia greup(2940.47±762.36)g (t=6.71 ,P<0.05). Conclusions Clinical symptoms of early-onset severe preeclampsia are severe , and have a higher incidence of abnormal prenatal outcomes. Prevention, prediction ,diagno-sis and management of preeclampsia are important for mothers and children.

Objective To evaluate the ultrasound guidance method in central venous catheterization (CVC) via the axillary vein.Methods Totally 1369 CVC patients in our center from November 2010 to October 2012 were enrolled in this study.They were randomly divided into two groups based on their different procedures:ultrasound group (n =687):the central veins were assessed using ultrasound,and catheters were placed via axillary vein with ultrasound guidance ; and control group (n =682):CVC was performed using the anatomical landmark method.The operation time,one-attempt success rate,complications,and malposition rate were compared between these two groups.Results The ultrasound group had significantly shorter operation duration than the control group [(7.8± 2.2) min vs (8.4 ± 1.7) min,P =0.000],higher one-attempt success rate [(96.0％ (659/687) vs 81.7％ (557/682),P =0.000],and lower complications and malposition rate [0.6％ (4/687) vs3.7％ (25/682),P=0.000; 0.6％ (4/687) vs2.1％ (14/682),P=0.017,respectively].Conclusions Compared with the conventional landmark method via subclavical vein,ultrasound-guided CVC via axillary vein method can effectively increase success rate,decrease operation duration,attempts of puncture,and complication rate,and avoid catheter malposition.Therefore,the ultrasound method can improve the safety and accuracy of the CVC procedure and deserves wider clinical application.

Objective To evaluate the functional magnetic resonance (MR) imaging in the assessment of renal involvement and pathological changes in patients with lupus nephritis (LN).Methods Seventeen patients with LN and 10 healthy controls underwent coronal echo-planar diffusion-weighted (DW) MR imaging and blood oxygen level dependent (BOLD) MR imaging of the kidneys with a single breath-hold time of 16 s.The apparent diffusion coefficient (ADC) and R2* value of the kidneys were calculated with high b values (b=500 s/mm2).The correlation between the renal injury variables and the ADCs or R2* values was evaluated.Results The mean ADC value of kidneys in patients with LN was (2.43+0.24)×10-3 mm2/s,the mean R2* values of the renal cortex and medulla were (11.72+2.35)/s and (13.07+2.35)/s respectively,which were all significantly lower than those in volunteers (P=0.045,P=0.048and P=0.001,respectively).In the patients with LN,the mean ADC values were positively correlated with estimated glomerular filtration rate (eGFR) (r=0.558,P＜0.05).There was a negative correlation between the ADC values of the right kidneys and pathological chronic indexes (r=-0.493,P＜0.05).Moreover,the R2*values of the renal medulla were negatively correlated with 24 hours proteinuria,serum creatinine,pathological active indexes.The patients were assigned to group A (class Ⅲ,Ⅳ,Ⅴ,n=8) and group B class Ⅴ + Ⅲ and Ⅴ + Ⅳ,n=9).The tubulointerstitial lesions in group B were more severe than those in group A,while the mean ADC values and R2* values of the renal cortex in group B were lower as compared to group A.Conclusion DW MR imaging and BOLD MR imaging may be used to non-invasively monitor the disease activity and evaluate the efficacy in lupus nephritis.

Objective To explore the diagnostic value of parametric imaging of contrast-enhanced ultrasound(CEUS) on recurrent hepatocellular carcinoma after liver transplantation.Methods CEUS images of 41 recurrent hepatocellular carcinoma after liver transplantation was analyzed by Sonoliver CAP software.The color code image,curve image and quantitative parameter of DVP of each recurrence lesion was recorded,then typed and analyzed statistically.Results The DVP patterns were classified into 3 types,they were washed out types,non-washed out types and negative types.The washed out types,non-washed out types and negative types on color code image and curve image of DVP were 70.73％ (29/41),24.39％ (10/41),4.88％ (2/41) and 63.41％(26/41),34.15％ (14/41) and 2.44％ (1/41) respectively.The maximum intensity,rise time,time to peak of the recurrence lesion and the surrounding liver parenchyma were (149.98± 65.29) ％,(12.32 ± 5.83)s,(13.01 ±6.07)s and (100±0.00)％,(26.10± 10.81)s,(29.69± 11.60)s respectively,and showed statistical differences (P ＜0.05).Conclusions The difference of blood perfusion between the recurrence lesion and the surrounding liver parenchyma can be displayed by DVP's dynamic,direct and quantitative imaging,which can be used to provide valuable information about the detection of intrahepatic lesion of recurrence after liver transplantation.

Aim To investigate the effects of anti-in-flammation and antioxidation of an amphiphilic curcu-min derivative (Curc-OEG)on CCl4-induced hepatic fibrosis in rats.Methods Rats were randomly divided into four groups:control group,model group,curcumin and Curc-OEG treatment group.All rats except those in control group were given subcuta-neous injection of CCl4 and olive oil mixture,twice a week for 8 weeks.After 4 weeks,rats of control and model group were trea-ted with normal saline intravenously,curcumin group were ad-ministered with curcumin 400 mg.kg -1 .d -1 by gavage and Curc-OEG group were treated with Curc-OEG 1 00 mg.kg -1 .d -1 intra-venously respectively.After 4 weeks treatment,the serum levels of ALT and AST were tested.HE and Sirus staining were used to evaluate the extent of liver inflammation and fibrosis.The mRNA expression levels of proinflammatory cytokines of NF-kB,IL-1 β, IL-6,TNF-α,COX-2 were observed with Real Time PCR.The level of MOD,SOD and GSH in liver of rats were quantified. Results The levels of ALT in control,model,curcumin and Curc-OEG group was (31 .7 ±8.7)U·L -1 ,(383.0 ±75.6) U·L -1 ,(406.3 ±204.7)U·L -1 ,(1 07.0 ±73.7)U·L -1 respectively;that of AST was (1 37.7 ±32.7)U·L -1 ,(585.3 ±36.7)U·L -1 ,(485.0 ±246.5)U·L -1 ,(202.7 ±56.0) U·L -1 respectively,Curc-OEG possessed more hepatoprotective effects than that of curcumin.Liver pathology showed Curc-OEG treatment could significantly alleviate steatosis,reduce inflamma-tion and apparently suppress hepatic fibrogenesis by reducing the thickness of bridging fibrotic septa.Compared with curcumin, Curc-OEG down-regulated mRNA and protein expression levels of NF-kB,IL-1 β,IL-6,TNF-α,COX-2 (P <0.05 ).Moreo-ver,Curc-OEG reduced the level of MOD and increased the lev-els of SOD and GSH.Conclusion Curc-OEG could more sig-nificantly protect the rat liver from CCl4-caused fibrogenesis by anti-inflammatory and antioxidant effect than curcumin.

Objective To explore the correlation between polymorphism of angiotensin converting enzyme (ACE) gene and hypertensive disorder complicating pregnancy (HDP) in Chinese people.Methods The 21 case-control studies on the correlation between polymorphism of ACE gene (genotype DD,DI,Ⅱ) and HDP in Chinese people were analyzed by meta-analysis.The analysis was performed on Review Manager 4.2 software.According to the result of test for heterogeneity,the random effects model was used to calculate the pooled OR value and 95% CI.Results Twenty-one case-control studies were enrolled in this meta-analysis,a total of 1486 HDP cases and 1758 controls were included.The pooled OR values (95% CI) of DD,DI,Ⅱ genotypes of ACE gene polymorphism for HDP risk were 2.60 (1.84-3.67),0.98 (0.76-1.27) and 0.46 (0.32-0.65) respectively.Conclusions Genotype Ⅱ of ACE is a protective gene against HDP and genotype DD is a susceptibility gene for HDP.

Oxidation and free radicals participate in the pathological process of multiple diseases in organisms, and acupuncture shows good effect in antagonizing oxygen stress (OS). This article reviews the effect of acupuncture in antagonizing oxygen stress and the mechanism of its anti-free radical effect in various diseases. The authors hold that acupuncture not only has a chain-blocking effect, but also has preventive and repairing effects of anti-oxidation. And anti-OS action is one of the important mechanisms of acupuncture.
