Objective To investigate the stroke occurrence of chronic kidney disease (CKD) and its related factors, especially the carotid atherosclerosis. Methods The data of stroke occurrence in 700 CKD patients hospitalized in Renji Hospital during 2007 were analyzed retrospectively. The incidences of stroke were compared among CKD [Ⅰ-Ⅱ, CKD Ⅲ-Ⅴ non-dialysis patients and dialysis patients. Carotid atherosclerosis of 409 CKD patients was examined by color Doppler ultrasound. The related factors were selected by Spearmnan correlation analysis and Logistic regression analysis. Results Of 700 CKD patients, 67 cases (9.57%) experienced at least one episode of stroke, which was much higher than that of general population. The related factors of stroke in CKD included GFR, age, SBP, CRP, Lpa, serum glucose, pre-albumin, HDL and carotid atherosclerosis. Logistic regression revealed that SBP (β=1.021, P=0.042), CRP (β=1.008, P=0.024) and carotid atherosclerosis (β =3.456, P=0.025) were risk factors of stroke in CKD. Incidence of carotid atherosclerosis was high (50.37%) in CKD patients, besides it was significantly higher in CKD patients with stroke history as compared to those without stroke history (80.0% vs 47.4%, P<0.01). Conclusions The incidence of stroke is quite high in CKD patients, which is closely associated with hypertension, inflammation and glyeolipid metabolism disorder. Carotid atherosclerosis is common in CKD patients with stroke, which may be helpful in screening cerebrovascular diseases in CKD patients.

ObjectiveTo observe the influence of different dietary protein intake (DPI) on nitrogen balance and nutritional indices in peritoneal dialysis (PD) patients, and explore the minimal DPI to maintain nitrogen balance.MethodsThirty-four PD patients were randomly divided into group A, B and C with DPI as 1.2, 0.9 and 0.6 g·kg-1·d-1 respectively. All the patients admitted into our hospital and completed a 10-day assessment for nitrogen balance, as well as nutritional status including serum albumin (Alb), pre-albumin at baseline, the 7th and 10th day. ResultsThe DPI of group A, B and C was (1.18±0.05), (0.87±0.02), (0.66±0.03) g·kg-1·d-1, whose differences were significant (P<0.01). The dietary energy intake (DEI) was 129.29 (117.57-133.89), 111.71 (100.42-133.47), 146.86 (128.03-163.18) kJ·kg-1·d-1 respectively. Nitrogen balance was positive in group A, B, C [2.99 (2.15-4.72) g, 1.20(0.59-1.89) g, 0.24 (-0.87-1.27) g]. The BUN decreased at the 7th and 10th day (P<0.01) in group C. The BUN and phosphorus in group A increased, but without significant difference as compared to baseline. No significant differences of nutritional status were found among three groups throughout the trial. ConclusionMinimal DPI 0.65 g·kg-1·d-1 plus the supplement of protein loss in dialysate can maintain the nitrogen balance in peritoneal dialysis patients.

Objective To compare the efficacy and safety of leflunomide (LEF) combined with medium/low dose corticosteroids and full dose of corticosteroids in the treatment of IgA nephropathy. Method Primary IgAN patients diagnosed by renal biopsy with 18?65 years old and eGFR≥30 ml·min?1·(1.73 m2)?1 and proteinuria>0.5 g/24 h were enrolled in a prospective controlled clinical study. They were randomly divided into leflunomide combined with medium/low dose corticosteroids (LEF group) and corticosteroids alone (steroid group). The primary outcomes were (1) end stage renal disease or dialysis (2) 50% increase in serum creatinine above the baseline. Secondary outcome was the remission of proteinuria. Results Ninety patients completed the follow?up. The 24?hour proteinuria at baseline were 2.00(1.10, 2.88) g and 1.87(1.13 ,3.08) g in LEF group and steroid group respectively. Compared with baseline, it was significantly decreased in both groups at 6 months [0.30(0.11, 0.93) g, 0.30(0.14, 1.33) g] and 12 months [0.30(0.09, 0.82) g, 0.32(0.14, 0.66) g], (P<0.05). Estimated glomerular filtration rate (eGFR) at baseline, 6 months and 12 months were (80.39 ± 28.56), (87.12±28.70) and (88.20±30.26) ml·min-1·(1.73 m2)-1. It was decreased in steroid group (P<0.05), while no significant difference was detected in LEF group[baseline (87.63 ± 27.35), 6 months (86.91 ± 32.45), 12 months (90.06 ± 30.00) ml·min-1·(1.73 m2)-1, P>0.05]. At 6 and 12 months, there was no significant difference in terms of 24?hour proteinuria, serum creatinine and eGFR (CKD?EPI) between groups (P>0.05). There was no statistically significant difference in adverse events between groups during the treatment (9/40 cases in LEF group and 11/50 cases in steroid group, P>0.05). The average follow?up was 79 months, and there was no difference in the renal prognosis between the two groups. Multivariate Cox regression analysis revealed that serum creatinine at baseline and renal interstitial inflammatory cell infiltration predicted the risk of the progress of IgA nephropathy. Conclusion Leflunomide plus medium/low dose corticosteroids has a similar effect as full dose of corticosteroids in IgA nephropathy and does not increase the risk for adverse events during the treatment.

BACKGROUNDMitochondrial dysfunction is linked to the pathogenesis of Parkinson's disease (PD). However, the precise role of mitochondrial DNA (mtDNA) variations is obscure. On the other hand, mtDNA haplogroups have been inconsistently reported to modify the risk of PD among different population. Here, we try to explore the relationship between mtDNA haplogroups and sporadic PD in a Han Chinese population.
METHODSNine single-nucleotide polymorphisms, which define the major Asian mtDNA haplogroups (A, B, C, D, F, G), were detected via polymerase chain reaction-restriction fragment length polymorphism or denaturing polyacrylamide gel electrophoresis in 279 sporadic PD patients and 510 matched controls of Han population.
RESULTSOverall, the distribution of mtDNA haplogroups did not show any significant differences between patients and controls. However, after stratification by age at onset, the frequency of haplogroup B was significantly lower in patients with early-onset PD (EOPD) compared to the controls (odds ratio [OR] =0.225, 95% confidence interval [CI]: 0.082-0.619, P = 0.004), while other haplogroups did not show significant differences. After stratification by age at examination, among subjects younger than 50 years of age: Haplogroup B also showed a lower frequency in PD cases (OR = 0.146, 95% CI: 0.030-0.715, P = 0.018) while haplogroup D presented a higher risk of PD (OR = 3.579, 95% CI: 1.112-11.523, P = 0.033), other haplogroups also did not show significant differences in the group.
CONCLUSIONSOur study indicates that haplogroup B might confer a lower risk for EOPD and people younger than 50 years in Han Chinese, while haplogroup D probably lead a higher risk of PD in people younger than 50 years of age. In brief, particular Asian mtDNA haplogroups likely play a role in the pathogenesis of PD among Han Chinese.

OBJECTIVEIn order to study on effects of soy extract on energy metabolims in ovariectomized rats.
METHOD90 Wistar rats were randomly divided into 9 groups: control group, sham group, model group, estrogen group, soy isoflavone group of high dose, soy isoflavone of low dose, soy extract of high dose, soy extract of low dose, 10 rats each group. Beside of control and sham groups, the rest rats were ovariectomized. One week after operation, the rats were treatmented with different drugs, measument of body weigh and feed weigh each week. Six week after operation, the rats were killed, serum were taken, abdomen lipid were removed and weight.
RESULTThe ovariectomized rats took more food and got weight gain significantly; Body mess index(BMI), Abdomen lipid weigh and food transform rate in Model group increased significantly than control and sham groups. Administration of estrogen or soy extract or soy isoflavone could block these changes in ovariectomized rats, but soy polysaccharides did not have the effects.
CONCLUSIONOvariectomized rats have imbalance of energy metabolism, weigh gain and accumulation of abdomen lipid; administration of estrogen, soy extracts or soy isoflavone could attenuate these changes induced by ovariectomizing.
