Objective To observed the alteration of the glomerular charge-barrier (GCB) in children with idiopathic nephrotic syndrome(INS) and relationship between GCB and severity of proteinuria. Mothods The clearance ratios of pancreatic to salivary isoamylase(CPAM/CSAM) were detected in 21 cases with INS and 29 healthy controls by use of a selective inbibitor, then use the clearance ration to show the CCB. Results The ratio of CPAM/CSAM in the cases with massive proteinuria was mean 1. 18 (range 0.82 - l .54), in the cases with no-massive proteinuria was mean 2.06(1 .22 - 3. 14), in healthy controls was 3 .33 (l. 18 - 6.54). There was a significant difference in ratios CPAM/CSAM between three groups. As all cases with INS, the ratio was very significantly negatively correlated with 24-hour urine protein quantity, but not correlated when 24 hour proteinuria was in excess of 50 mg/kg. Conclusion GCB of the cases with INS is reduced, and of the cases with massive proteinuria almost dissappeared.

Objective To carry out a taxonomic identification of a strain of claviform bacteria iso-lated from prostatic fluid of a patient who suffered from chronic prostatitis, and to approach its phylogenic and biologic position. Methods We undertaked an initial identification by phenotypic characters such as morphologecal, physiological and biochemical characteristics to ascertain its phylogeny by chemical composi-tion analysis of cell wall and 16S rRNA gene sequencing and alignment. Results A club-shaped gram posi-tive rod bacillus was isolated in pure culture state. Its biochemical reactions were not active. The diamino-acid of cell wall was meso-diaminopimelic acid (meso-DAP) and it had wall chemotype Ⅳ ( contained arabi-nose, galactose and maltose ). Sequence searches of the GenBank database revealed that this strain had a highest level of 16S rDNA sequence similarity (99.4%) to C. tuberculostearicurn strain ATCC35692 with only 8 nucleotides difference. Conclusion On the basis of phenotypic and phylngenetie analysis, it is rea-sonable to assign this strain to the species C. tuberculostearicum, and this is the first isolation of C. tubercu-lostearicum from prostatic fluid home and abroad.

BACKGROUND: The investigation of culturing, passaging and establishing human limbal stem cells can strengthen the recognition of the stem cells and provide the enough cellular reserve for the basic and clinical research of limbal stem cell transplantation.OBJECTIVE: To explore a method of pessaging and establishing cell line of human limbal stem cells cultured in vitro.DESIGN: Randomized controlled observation.SETTING: Gannan Medical College.MATERIALS: The experiment was performed at Scientific Center of Gannan Medical College and the National Key Laboratory of Ophthalmology Hospital Affiliated to Sun Yat-Sen University from June 2003 to April 2004. Fresh human limbus corneae were isolated from two healthy donors. Procedures were performed according to the informed consent of the donors. Main reagents contained RPMI-1640 (Sigma R8755, containing L-glutamine) and 200 g/L fetal calf serum (FCS) (Gibco 16140-071). DMEM medium, chondroitin sulfatase and human epidermal growth factor (hEGF) were purchased from Sigma Co. USA; HEPES and DMSO were bought from Gibco, USA; 100% glycerinum was purchased from Yunjia Huangpu Pharmaceutical Product Limited Company, PRC; glutaraldehyde was bought from E.Merk, Germany; Alcohol, chlorhydric acid, acetone and methyl aldehyde were purchased from Beijing Chemical Agent Company, PRC; 0.25% parenzyme was bought from Shanghai Xinhua Pharmaceutical Factory, PRC.Above-mentioned reagents were analytical pure grade.METHODS: After digestion, human limbal tissues in limbal basilar part with an abundant pigment were cultured in the culture flask containing RPMI-1640 and 200 g/L FCS and in culture dish containing amniotic extracellular matrix (AECM) as the cultural supporter. Primary and passage cells were observed under light microscope and scanning electron microscope (SEM). The revival ratio of stem cell refrigeration of every generation was calculated by the trypanblau exclusion experiment.MAIN OUTCOME MEASURES: ① Observational results of limbal stem cells during the primary culture and serial subcultivation in vitro, and ② revival ratio of stem cell refrigeration.RESULTS: ①Findings of primary culture: Most limbal stem cells in the culture flask had the adherence and were arrayed uniformly sparsely to form monolayer and adhered to the bottom of culture flask under the inverted phase contrast microscope after 1-day culture. ② Findings of serial subcultivation: After human epidermal growth factor (hEGF) was added into the second passage, cells were scattered into the monolayer and adhered to grow quickly.Morphological variability of all the cells increased obviously when passage the 30th generation. The cellular volume was obviously increasing, and the round or irregular round cells gathered together. The 33rd generation human limbal stem cells still could vigorously differentiate, proliferate and grow in ACEM. ③ The revival ratio of stem cell refrigeration was 82.2%.CONCLUSION: The human limbal stem cell lines were preliminarily established by culturing and freezing the cells of 33 generations in vitro. The human limbal stem cell lines preferred to grow in the culture dish containing AECM as the cultural supporter.
