2.Ten Cases of Immunoglobulin A Nephropathy with an Onset of Acute Glomerulonephritis
Journal of Applied Clinical Pediatrics 1992;0(05):-
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.

6. Inductive effects of galangin on apotosis of human papilloma virus positive cervical cancer cells
Chinese Traditional and Herbal Drugs 2017;48(5):941-945
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 .

OBJECTIVE:
To study the characters of oscillatory potentials (OPs) of electroretinogram (ERG) after methanol intoxication in rats.
METHOD:
The SD rat models of methanol intoxication were established and divided into control group, 3-day intoxication group, 7-day intoxication group. The changes of OPs of ERG were recorded in a dark room.
RESULTS:
The total amplitudes of 3-day and 7-day intoxication groups decreased approximately 50% compared with that of the control group, while the schedule delayed approximately 16% and 61%, respectively.
CONCLUSION
The characters of methanol intoxication in rats included delay in schedule and decline in the total amplitude of OPs.

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.
