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 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 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 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.

OBJECTIVETo investigate the correct method of bone resection and posterior capsular soft tissue releasing in total knee arthroplasty (TKA) for the patients with rheumatoid arthritis with stiff knee in flexion.

METHODSFrom November 2009 to January 2012,15 patients with rheumatoid arthritis with stiff knee in flexion underwent primary TKA and releasing of the posterior soft tissues. There were 7 males and 8 females,aged 22 to 75 years old (58.7 years old on average). The preoperative range of movement(ROM) was (3.2 ± 1.7)°. According to Knee Society score (KSS) criterion, the preoperative clinical score was 23.3 ± 12.5 and functional score was 35.2 ± 9.8. Based on the correct osteotomy, effective releasing of posterior structures was used for different degrees of flexion contracture during the TKA procedure.

RESULTSAll the patients were followed up, and the average duration was 2.3 years (1.6 to 3 years). At the latest follow-up,the KSS clinical score was 81.7 ± 6.5 and functional score was 82.8 ± 9.3. The flexion and extension ROM of the knee joint was (103.5 ± 13.1). Three knees remained 50 flexion contracture deformity, but the function of the affect knees was good.

CONCLUSIONThe effective releasing of the soft tissue of posterior capsule is a major management for correction of the flexion contracture in TKA. The correct releasing of posterior structure can not only achieve fundamental gap of TKA but also effectively avoid bone over-resection.

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.

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.
