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 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.

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 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.

Objective To identify the outcome of pregnancy and the alteration of renal function in women with nephrotic syndrome. Methods From 2003 to 2007, 59 pregnant women with nephrotic syndrome in our hospital were enrolled in the study. Their clinical data were retrospectively analyzed, including the time of kidney disease onset, 24-hour proteinuria, serum albumin, serum creatinine, blood uric acid, blood pressure, fetal survival, fetal mortality, rate of premature delivery, birth weight of the newborn, and proteinuria, renal function, blood pressure of the patients during their postpartum follow-up. Logistic regression analysis was used to identify the risk factors influencing the outcome of the patients and the newborns. Results The average gestational week was (20.35±9.40) weeks when proteinuria was detected in these pregnant women. The 24-hour proteinuria ranged from 3.5 to 15 g/24 h (median 5.1 g/24 h). The serum albumin was between 10 and 28 g/L (median 22.5 g/L). The serum creatinine was between 32 and 825 μmol/L (median 84 μmol/L) and the serum uric acid ranged from 196 to 793 μmol/L (median 385.5 μmol/L). Pregnancy-induced hypertension syndrome occurred in 75% of the patients, among whom 55.5% suffered from preeclampsia. Forty-three (72.9%) newborns survived , among whom 76.7% (33/43) were premature births and 62.8% (27/43) were low birth weight infants. 50% of the pregnant women still had nephrotic syndrome after delivery. 75% of 24 patients with pre-existing chronic glomerulonephritis had increased proteinuria during pregnancy. Among the 38 patients with renal insufficiency, 36.8% had poorer renal function after delivery. 23.7% of the patients progressed into end stage renal failure after delivery, 80% of whom had serum creatinine ≥ 265 μmol/L. 89% of the patients had persistent hypertension after childbirth. The Logistic regression analysis indicated hyperuricemia during pregnancy (P=0.018, OR=1.012) and the increase of serum creatinine (P=0.039, OR=1.005) were risk factors of renal failure in pregnant women after delivery. Hyperuricemia (P=0.012, OR=1.006)was the risk factor of fetal death. Conclusions Pregnancy with nephrotic syndrome leads to a low fetal survival. Hyperuricemia is the most important risk factor of the poor outcome of pregnant women and newborn.

Objective To compare the efficacy between the two-cuff swan neck catheter and the Tenckhoff catheter in continuous ambulatory peritoneal dialysis (CAPD) patients prospectively. Methods One hundred and ten patients with end-stage renal disease (ESRD) were selected as candidates, who received catheter implantation and CAPD therapy for the first time. Patients were divided into group A (swan neck catheter group) and group B (Tenckhoff catheter group), 55 patients for each group. Catheters of beth groups had a straight end and were implanted by routine surgical procedure. One-year follow-up was performed and information was recorded such as complications, survival time, quit of dialysis, death, etc. Survival analysis was carried out by Kaplan-Meier method and Log-Rank tests. Results At the end of follow-up, 17 patients died, 3 received renal transplantation, 8 were transferred to hemodialysis, 3 went to other hospitals, and 79 patients (71.8%) remained in our department for CAPD. Twenty-six patients of both groups had peritonitis with a total of 35 occurrences. The total incidence of peritonitis was 0.32 times/patient year, with the detailed figure of 0.35 times/patient year for group A and 0.29 times/patient year for group B respectively (P0.05). The time interval between the catheter implanting and the onset of peritonitis was (30±29) weeks and (29±24) weeks for group A and group B respectively (P0.05). The risk of developing peritonitis in both groups was 26.97% within 1 year. Tunnel infection occurred in 2 patients and exit-site infections in 9 patients of two groups. The incidence of tunnel plus exit-site infections was 0.1 times/patient year. Incidence of tunnel infection and the exit-site infection for group A was lower than that of group B (0 vs 0.036 times/patient year and 0.06 times/patient year vs 0.11 times/patient year respectively). However, the difference was not significant (P0.05). Mechanical complications of catheter (catheter migration, omcntum wrapping, leakage of peritoneal dialysates, slip out of outer cuff), incidence of inguinal hernia and bellyache between two groups were not significantly different (P0.05). There were 4 cases of catheter drawing in each group. Both two groups had the same 12-month technical survival rate as 92.73%. Of 17 dead cases, 7 were in group A and 10 in group B (P0.05). The main death causes were cardiocerebral events (47.1%) and infections (23.5%). The 12-month survival rate was 86.34% for group A and 80.68% for group B (P0.05). Conclusions There are no significant differences of infection, mechanical complications, technical survival rate and patients' survival rate between two groups. The efficacy of swan-neck catheter is similar to Tenckhoff catheter in CAPD patients.

Objective To probe into the value of micro-perfusion examination at the early stage after right lobe living donor liver transplantation by contrast-enhanced ultrasound(CEUS). Methods Twenty-six recipients of right lobe living donor liver transplantation received CEUS examination at 1,7,15 and 30 days respectively after operation using contrast medium SonoVue. Perfusion patterns were observed and analyzed considering operation method. Results Of 26 recipients, 15 cases showed normal perfusion patterns with normal hemodynamics; 11 cases showed abnormal perfusion patterns with abnormal hemodynamics:8 had conduit venous obstruction,4 high portal vein blood flow. The abnormal patterns was in the early arterial phase of enhancement process at the first day examination, showing hyper- and hypo- enhancement area compared with normal liver parenchyma. And the difference gradually disappeared in the subsequent examination. Conclusions Abnormal micro-perfusion patterns are highly related to abnormal inflow and outflow in the early post operation stage. The main reasons are conduit venous obstruction and excessive perfusion of portal vein. CEUS can be used as an effective method in evaluating the graft micro-perfusion.
