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.

OBJECTIVETo investigate the technique and therapeutic effect for correction of sunken eyes combined with ptosis.

METHODSIn order to adjust the levator muscle tension and the relationship between levator aponeurosis and tarsus plate, multiple individualized treatment was selected, including levator aponeurosis restoration, levator aponeurosis plication, or shorten, or combination. Then the orbital fat was transferred to the depressed area, or autologous fat particles were collected and injected into the depressed area within the orbital fat fascia. After the orbital septum fascia was restored, the incision was closed primarily.

RESULTS15 cases (30 eyes) were treated. 11 cases were followed up for 6-40 months (average, 9.5 months) with satisfactory cosmetic and functional result. No recurrence of ptosis happened.

CONCLUSIONSOne-stage correction of sunken eyes combined with ptosis can be achieved with autologous fat injection or orbital fat transposition. Good cosmetic and functional result can be achieved.
