Objective To investigate the clinical characteristics of radiographic contrast-induced nephropathy(RCIN) in children for improving the knowledge of this disease.Method The clinical data of 6 hospitalized children with RCIN collected from Oct.1998 to Dec.2007 were evaluated retrospectively.Results Of 92 patients who had cardio-angiography,intravenous pyelography,renal arteriography,cerebral angiography,and CT with contrast medium,6 cases(2 girls and 4 boys,aged 2-17 years old) had RCIN.Among the 6 children,5 cases [serum creatinine(Scr) was from 168.3 to 249.7 ?mol/L] showed non-oliguria-type acute renal failure;1 case(Scr was 583.1 ?mol/L) showed oliguria-type acute renal failure,and renal biopsy pathology findings showed that renal tubular epithelial cells were vacuolar degene-ration,striated border fell off,renal tubular epithelial cells were necrotic mulifocally,while the glomeruli were normal.Hematuria in 2 cases with primary disease aggravated;2 cases showed microscopic hematuria;1 case had proteinuria(+),1 case appeared microscopic hematuria and proteinuria(+).Five patients with non-oliguria-type acute renal failure were cured successfully after the medication of 10-21 days.Another case with oliguria-type acute renal failure was well after interrupted hematodialysis for 13 days and medication.Conclusion Children suffering RCIN usually manifest non-oliguria-type acute renal failure,and most of them can be cured by hematodialysis and medication mostly.

50 000 bp)was extracted from frozen gastric cancer tissue and their corresponding normal samples and used for RLGS assay.The genome DNA was digested by methylation-sensitive restriction enzyme Not Ⅰ, and labeled by radioisotope ~(32)p,then separated by two-dimensional electrophoresis and autoradiography. Experimental conditions for each step were optimized step by step.DNA fragment sequences for the dots on scanning profile were identified according to the human RLGS database.Results RLGS assay was set up and used to get the RLGS profiles of the representative tested samples successfully.These profiles can display more than 1 200 available dots averagely,the profiles of high quality DNA sample can display more than 1 800 dots which is the average level at an excellent RLGS lab,discrepant dots which had weaken or enhanced signals and their sequence information were obtained.The result can be reproduced.Conclusion The RLGS assay is established,stabilized for detection of DNA methylation of tissue samples.

The morphological indexes of the Scuophularia ningpoensis seedlings including the longth, diameter and weight were measured, clustering analysis was used to set up the standard quality grading of seedlings of S. Ningpoensis by SPSS. Field experiment was carried out to measure the indicators of plants growth and development, the yield and the quality. The results showed that the growth and yield of class I seedlings were better than those of class II and III. The content of main active ingredients was affected barely by seedlings classification. To ensure the quality, class II seedlings or above should be used for plantation. The established quality classification standard of S. ningpoensis seedlings was scientific and feasible, and provides the basis for the standardized cultivation of S. ningpoensis.

The author detected the genetic diversity and genetic relationship within and among eight medicinal species of Dipsacus by the approach of sequence-related amplified polymorphism (SRAP). The associated genetic parameters were calculated by POPGENE 1.31. The Genetic distance was calculated by TREECONW and the systematic diagrams of genetic relationship were clustered by UPG-MA. The results showed that, using 26 primers, a total of 558 bands were produced, of which 539 were polymorphic loci. There was a high level of genetic diversity among species (PPB = 96.59%, Na = 1.9659, Na = 1.3375, H = 0.2143, I = 0.3423). However, genetic diversity was lower within species, the average of genetic parameters was PPB = 6.97%, Na = 1.0697, Na = 1.0311, H = 0.0187, I = 0.0291. The Nei's genetic differentiation coefficient was 0.9126, indicated that most of the genetic variation existed among species. By clustering analysis, different individuals gathered in the same group and the classified result of SRAP marker between traditional modal characters was almost same. The results confirmed that SRAP marker can be used as one of the effective methods to reveal the genetic diversity and relationship among medicinal species of Dipsacus.

Objective To evaluate the efficacy of moxifloxacin-based triple therapy combined with rebamipide for Helicobacter pylori (Hp) eradication in type 2 diabetic patients.Methods Two-hundred age and sex matched type 2 diabetic patients with Hp infection and accompanied by gastrointestinal symptoms were assigned into rebamipide group (n =100) and placebo group (n =100).Both groups received moxifloxacin-based triple therapy for 10 d to eradicate Hp.Rebamipide was administrated in rebamipide group and placebo was administrated in placebo group for 30 d.All patients proceeded 14C-urea breath test (14C-UBT) hefore and 7-8 weeks after eradication therapy.The blood sugar indices,gastrointestinal symptom scores and Hp eradication rates were measured and compared.Those who had gained successful Hp eradication in both groups proceeded 14 C-UBT again 12 months after eradication therapy,and the re-infection rates of both groups were compared.Results There were no significant differences in the average fasting glucose,postprandial glucose and HbAlc levels between the rebamipide group and the placebo group before and after therapy (P ＞ 0.05),the gastrointestinal symptoms of the rebamipide group were improved more markedly than those of the placebo group after therapy (Rome Ⅲ Criteria,2.1 ± 0.9 vs.4.4 ± 0.7,P ＜ 0.01).The Hp eradication rate with both intention-to-treat (ITT) and per protocol (PP) analysis of the rebamipide group were higher than that of the placebo group [86.0％ (86/100) vs.73.0％ (73/100),P ＜ 0.05 and 92.5％ (86/93) vs.76.8％ (73/95),P ＜ 0.01].The re-infection rates with both ITT and PP analysis of those who had successful eradication in rebamipide group were lower than that in placebo group [19.8％ (17/86) vs.35.6％ (26/73),P＜0.05and20.5％ (17/83) vs.36.6％ (26/71),P＜0.05].Conclusions Moxifloxacin-based triple therapy combined with rebamipide has a more beneficial effect on Hp related symptoms,a higher Hp eradication rate and a lower Hp re-infection rate for type 2 diabetic patients.
