Purpose:To investigate the relationship between involved extent of lymph node parenchyma and prognosis of patients with stageⅢ non-small-cell lung cancer (NSCLC) and define the appropriate surgical indications for the patients. Methods:From 1988 to 1998,one hundred and sixteen patients with NSCLC underwent systematic lymph node dissection and were diagnosed to have metastasis in mediastinal lymph node (N_(2) disease), whose clinical data were reviewed. According to the clinical and pathologic characteristics of the involved mediastinal lymph node, the patients were divided into subgroups. Survival rates were calculated and survival curves were prepared by Kaplan-Meier method. Survival differences among the subgroups were compared by Log-Rank test. Results:Involved extent of lymph node parenchyma had an important effect on the prognosis. In N_(2) disease with extra-capsular metastasis and intact capsule, 5-year survival rates were 9.8% and 18.8%, respectively. The survival difference between extra-capsular metastasis subgroup and inner-capsular metastasis subgroup was of statistical significance (P

Objective To establish a methodological study pattern of quantitative analysis of multi-components by single marker ( QAMS) , and examine its feasibility and technical applicability in the quality control of compound preparation of traditional Chinese medicine-Jinhoujian spray. Methods Gas chromatographic method ( GC) was used and naphthalene served as the internal standard. Menthol was used as the reference substance. The relative correlation factors ( RCF) of 1,8-Cineole, camphor and borneol to menthol were calculated and established to carry out QAMS.The accuracy of this method was confirmed by comparison of internal standard method. Results The reproducibility of relative correction factor was perfect. The two methods did not show significant difference in 10 bathes of samples. Conclusion The QAMS method is feasible, credible, and can be used to determine active ingredients in Jinhoujian spray.

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.

OBJECTIVE: To assess the diagnostic value of CT peritoneography for peritoneal complications of continuous ambulatory peritoneal dialysis (CAPD). METHODS: CT peritoneography in 11 CAPD patients with clinically suspected dialysis-related complications was prospectively studied. The CAPD patients were all treated in Renji Hospital from 2005 to 2007. CT images were reviewed according to the evidence of peritoneal leaks, hernias, loculate pleural fluid collections, and adhesions. RESULTS: Abnormal findings were found in 9 of 11 CAPD cases including inguinal hernias (3 cases), umbilical hernia (1 case), hydrocele (1 case), leaks in catheter tunnel (2 cases), and peritoneal adhesions (2 cases). Parts of them were confirmed by surgical operation. CONCLUSION: CT peritoneography is useful for the evaluation of complications related to CAPD, and it offers excellent tissue contrast and multiplanar imaging for assessment of the complications.

Objective To elucidate the prevalence and risk factors of cardiovascular disease (CVD) in end-stage renal disease (ESRD) patients on peritoneal dialysis (PD), and to investigate the associated problems in treatment. Methods A total of 254 PD patients in our division were enrolled in this study. CVD history, laboratory measurements, examinations of carotid atherosclerosis and left ventricular hypertrophy by ultrasonography were collected and associated factors were analyzed. The median follow-up time was 49 months. Results The overall prevalence of CVD was 37% (93/254). Diabetes, longer dialysis duration, hypertfiglyceridemia, hypoalbuminemia, hypoprealbuminemia were commonly found in the patients with new CVD event. The patients without pre-existing CVD had the higher Ccr, Kt/V, D/Pr, nPCR, serum albumin level. In those with pre-existing CVD, the hypertriglyceridemia and the duration of dialysis were independent predictors of progression of CVD. Differences of LAD, LVST, LVMI and IMT were significant between with and without pre-existing CVD groups. Kaplan-Meier curves showed that the presence of CVD was the independent risk factor of survival. Alb<330 g/L, LAD>39.6 mm and peritonitis were risk factors of CVD. Conclusion The prevalence of CVD in PD patients is quite high. CVD history should be realized, dialysis adequacy should be maintained, and peritonitis should be prevented.

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.
