Objective To analyze the clinical features of immunoglobulin A(IgA) nephropathy(IgAN) occurring in the context of pre-vious acute glomerulonephritis.Methods The clinicopathologic features of 108 cases(77 males,31 females,aged 3.2 to 14.0 years old) of IgAN were analyzed restrospectively with the onset of acute glomerulonephritis in this department from Jan.1994 to Dec.2005.Results Of 108 cases with IgAN,10 cases were with the onset of acute glomerulonephritis. All the 10 cases presented with edema, hematuria and proteinuria.Eight cases had macroscopic hematuria, lasting for 2 days to 2 months.Four cases had recurrent macroscopic hematuria,microscopic hematuria lasting for 16 months.Urine protein qualitative +-+++ lasted for 1-8 months.Two cases had hypertension;2 cases had increasing blood uria nitrogen and serum creatinine.The increase of anti-streptolysin O(ASO) titer was detected in 5 of 9 cases.Two cases had a high titer of DNase-B antibody, and 4 cases had hypocomplementemia.Eight cases had prodromal infection with an interval time varying from 1 to 5 days.Renal biopsies revealed mesangial proliferative glomerulonephritis in 9 cases and focal segmental glomerulosclerosis in 1 case, all with mesan-gial IgA deposition.Conclusions The interval time between the prodromal infection and nephritis symptoms is mostly short in IgAN with the onset of acute glomerulonephritis, while macroscopic and microscopic hematuria remain a fairly long time or recurrently aggravate. Renal biopsy is necessary to diagnose IgAN for this kind of children.

Objective: To explore the inductive effect of galangin on HPV-positive human cervical cancer cells and the possible mechanism. Methods: Two HPV-positive human cervical cancer cell lines (SiHa cell and HeLa cell) and one HPV-negative human cervical cancer cell line (C-33-A cell) were given different concentration of galangin (20, 40, and 80 μmol/L) for 24, 48, and 72 h. Three human cervical cancer cell lines and relative cell viabilities were determined by the MTT method. Apoptosis and cell cycle were analyzed by flow cytometry. Western blotting analysis was used to determine the protein expression levels of Bcl-2 family proteins. Results: Cell proliferation of two HPV-positive human cervical cancer cells was significantly inhibited by galangin in a dose- and time-dependent manner, and galangin had no effect on cell proliferation of HPV-negative human cervical cancer cells. Cell cycle detection results showed that galangin could reversibly arrest the two HPV-positive cell lines, either in G1 or in G2/M phases. Flow cytometry results showed that beyond certain galangin concentration or/and over 24 h exposure, the cells underwent apoptosis. The data of Western blotting showed that 40 μmol/L galangin up-regulated the expression levels of Bad, Bid, and Bax, but down-regulated Bcl-2 and Bcl-w. Conclusion: Galangin can inhibit the proliferation of HPV-positive cervical cancer cells and promote apoptosis, which may be associated with the regulation of Bcl-2 family proteins expression.

Objective To investigate the role of thrombelastography(TEG) in assessing the risk of bleeding and diagnostic value in patients with acute leukemia(AL) .Methods The TEG and PLT data were counted in 127 patients(272 sets of data) who were diagnosed with AL .Those patients were divided into two groups :group 1 (including patients with bleeding) and group 2 (in‐cluding patients with no bleeding) .The indicators(R values ,K values ,α‐angle ,MA values)and PLT count were compared between two groups .Those data with PLT<30 × 109/L of these two groups also were divided and the 4 indicators of TEG were compared between the two groups .We used the ROC curve to evaluate the sensitivity and specificity in assessing the risk of bleeding .Results According to the data in total ,the K value ,R value of the group 1 were higher than those of the group 2(P<0 .05);theα‐angle and MA value ,PLT counts of group 1 were lower than those of the group 2(P<0 .05) .In those AL patients whose PLT<30 × 109/L ,the K value of the group 1 was higher than that of the group 2(P<0 .05);theα‐Angle and MA value of the group 1 were lower than those of the group 2(P<0 .05);R values and PLT count were not different between the two groups(P>0 .05);the are‐as under the ROC curve about the PLT counts ,MA value andα‐angle were more than 0 .5 (0 .750 ,0 .740 and 0 .653) .Conclusion T EG could predict the risk of bleeding in acute leukemia patients and it could be used in clinical application .

alphaB-crystallin is the structural protein of vertebrate lens, which is widely expressed in non-lens tissue. As one of the heat shock protein family members, alphaB-crystallin possesses biological properties of molecular chaperones and anti-apoptotic effects. Multi-factor injuries, such as retinopathy, inflammation and nervous system diseases, have a closely relationship with alphaB-crystallin. This paper reviews the research progress of the expression and mechanism of alphaB-crystallin in retina and extraocular tissues and organs.

OBJECTIVE: To compare the correlation between contrast vision (LV) and sweep visual evoked potential acuity (SVEP-A) among people with emmetropia, mild myopia, and moderate myopia. METHODS: The CV and SVEP-A were tested individually in 96 eyes from healthy young volunteers, including 37 eyes of emmetropia, 27 eyes of mild myopia, and 32 eyes of moderate myopia. The statistic analysis was done by ANOVA analysis and rank sum test. RESULTS: (1) With the decrease of contrast, CV and SVEP-A decreased in every group. (2) At 100% contrast, the difference of CV between emmetropia and mild myopia had statistical significance (P<0.05). At 100%, 25% and 10% contrast, the difference of CV between emmetropia and moderate myopia had statistical significance (P<0.05). (3) In the same group, the difference of 100% and 25% contrast had statistical significance (P < 0.05). So was between 100% and 10% contrast. (4) At 100% and 10% contrast, the difference of CV and SVEP-A had statistical significance (P < 0.05). CONCLUSION The CV of myopia relates to many factors including ametropia and fundus lesions. The correction of ametropia is important to the values of CV and SVEP-A.
