The ability to identify the yeast-like fungi by YST identification cards and pyrosequencing analysis / 中华检验医学杂志

Objective To evaluate the ability of Vitek 2 Compact YST identification cards and pyrosequencing analysis for identifying the clinical isolates of yeast-like fungi.Methods Vitek 2 Compact YST identification cams and ITS1 region pyrosequencing analysis were used to identify the clinical isolates of yeast-like fungi at Jinan Military General Hospital in 2011.The strains which could not be identified to species by pyrosequencing analysis were identified again by the method of ITS1 region Sanger sequencing.The strains with inconsistent identified results by YST and pyrosequencing were identified again using API 20C.Results A total of 282 srtains were isolated from various clinical specimens for culturing in 2011.In addition to the three which could only be identified to similar species,other strains could be clearly identified to species by the method of ITS1 reverse pyrosequencing.Three strains which failed identified to species by pyrosequencing couldn't be distinguished fully by the method of Sanger sequencing.There were 7 strains unidentified,14 strains low discrimination(％ id ＜ 80％),and 6 strains misidentification using YST cams.The identification coincidence rate was 90.4％.The identification coincidence rates were various in different species of yeast-like fungi using YST cards.Conclusions The vast majority of clinical isolates of yeast-like fungi could be identified by ITS1 reverse pyrosequencing analysis.Vitek 2 Compact YST caRD basically meets the needs.But attention should be paid to the standard operating and regular internal quality control.For some rare species it is also needed to combine the source of specimen,colonies and characteristics to determine the identification results for the rare stains.

Role of hepatitis B virus infection in pathogenesis of IgA nephropathy / 中华预防医学杂志

<p><b>OBJECTIVE</b>To clarify the relationship between hepatitis B virus (HBV) infection and IgA nephropathy (IgAN).</p><p><b>METHODS</b>HBV antigen (HBAg) in renal tissues of the patients with IgAN was detected by immunohistochemical technique, the carrier status and localization of HBV DNA in renal tissues were determined by Southern blot analysis and in situ hybridization.</p><p><b>RESULTS</b>Serum HBsAg was detected in 18 of the 100 patients with IgAN (18%), HBAg was detected in 31 of 100 patients (31%) in their renal tissue and in 20 of 31 patients (65%) in their glomeruli, and both HBsAg and HBcAg were detected in 10 of 31 patients (32%), respectively. HBcAg was also found in tubular epithelia (45%, 14/31) and renal interstitium (6%, 2/31), respectively. Five of six cases were proved to be positive of integrated-form HBV DNA in their renal tissue by Southern blot analysis. In situ hybridization demonstrated that HBV DNA was 8/8 and 6/8 positive in their renal tubules and glomeruli of all eight specimens, localized in the nucleus of tubular epithelial cells, glomerular mesangial cells, as well as infiltrated interstitial lymphocytes.</p><p><b>CONCLUSION</b>HBV infection closely related with IgAN and HBV infection might be involved in pathogenesis of IgAN.</p>

Effects of hypoxia and hyperoxia on the regulation of the expression and activity of matrix metalloproteinase-2 in hepatic stellate cell / 中华病理学杂志

<p><b>OBJECTIVE</b>To study the effects of hypoxia and hyperoxia on the expression and activity regulation of matrix metalloproteinase-2 (MMP-2) of the hepatic stellate cell (HSC).</p><p><b>METHODS</b>The expression of MMP-2, tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) and membrane type matrix metalloproteinase-1 (MT1-MMP) in cultured rat HSC under hypoxic or hyperoxic conditions were detected with immunocytochemistry (LSAB method), the contents of MMP-2, TIMP-2 in culture supernatant with ELISA and the activity of MMP-2 in supernatant with zymography.</p><p><b>RESULTS</b>(1) In the situation of hypoxia for 12 h, the expression of MMP-2 increased (hypoxia group positive indexes: 5.7 +/- 2.0; control: 3.2 +/- 1.0; P < 0.01), while TIMP-2 decreased (hypoxia group positive indexes: 2.5 +/- 0.7; control: 3.6 +/- 1.0; P < 0.05) in HSC, and the activity of MMP-2 in supernatant declined obviously (hypoxia group: 7.334 +/- 1.922; control: 17.277 +/- 7.424; P < 0.01). At the different time courses of hypoxia, the change of expression and activity of MMP-2 was most notable at 6 h. (2) In the situation of hyperoxia for 12 h, the protein contents of MMP-2, TIMP-2 in supernatant were both higher than those of the control, especially the TIMP-2 (hyperoxia group A(450): 0.050 +/- 0.014; control: 0.022 +/- 0.010; P < 0.01), and so was the activity of MMP-2 (hyperoxia group total A: 5.252 +/- 0.771; control: 4.304 +/- 1.083; P < 0.05). The expression of MT1-MMP was also increased.</p><p><b>CONCLUSIONS</b>The HSC is sensitive to the oxygen. Hypoxia accelerates the expression of MMP-2 and the effect is more marked at the early stage. Hyperoxia increases the activity of MMP-2.</p>

Study of the expression of matrix metalloproteinase and its tissue inhibitor in hepatocellular carcinoma / 中华消化杂志

Objective To study the expression of matrix metalloproteinase (MMP) and the tissue inhibitor of matrix metalloproteinase (TIMP) in hepatocellular carcinoma (HCC) and its relation with the prognosis of patient. Methods MMP 1,MMP 2,MMP 9 and TIMP 2 in human HCC tissue and HCC cell line were measured and quantified with immunohistochemistry, Northern blot hybridization and image analysis. Results MMP 1,MMP 2 and MMP 9 were localized in the cytoplasm of tumor cells. The 5 years survival rate were markedly higher in the cases of MMP 1 negative, MMP 9 negative, both MMP 1 and MMP 2 negative or both MMP 1 and MMP 9 negative staining than that of the positive cases ( P
