7.The regulation roles of protein kinase C alpha in enhanced expression of type Ⅰ inositol 1,4,5-trisphophate receptors induced by tumor necrosis factor alpha
Journal of Chinese Physician 2013;15(8):1013-1017
Objective To investigate the signal mechanism of protein kinase C alpha(PKC-α)participated in enhanced expression of type Ⅰ inositol 1,4,5-trisphophate receptors (IP3 RI) induced by tumor necrosis factor alpha(TNFα),in order to delineate the mechanisms of decreased glomerular filtration rate (GFR) in hepatorenal syndrome caused by TNFα.Methods The glomerular mesangial cells (GMCs)line from rats was chosen as experimental material.GMCs were divided into control (D),TNFα-2 h,TNFα-4 h,TNFα-8 h,and TNFα-24 h groups.Moreover,another two groups were sanflngol-8h (S),TNFα + Sanfingol-8h(TS)groups.The effect of TNFα on the expression of IP3RI was detected by immunocytochemical staining,Western blotting,teal time-polymerase chain reaction (PCR) assays.Results Immunocytochemical staining demonstrated that IP3 RI was mainly distributed in cytoplasm of GMCs.Enhanced positive staining was determined in all TNFα-treated groups,especially in TNFα-8 h group.Western blotting demonstrated that the expression of IP3RI protein was significantly higher in TNFα-4 h,TNFα-8h and TNFα-24 h groups than control group(4 h:1.82 ± 0.63 ; 8 h:2.95 ± 0.66 ; 24 h:2.48 ± 0.72 ; D:1 ±0.02 ; F =9.24,P < 0.05).The expression of IP3 RI protein was the highest in TNFα-8 h and TNFα-24 h groups(P <0.05).No difference was found among S,TS,and control groups(S:1.39 ±0.65; TS:1.35± 0.37 ; P > 0.05).Real time-PCR found the expression of IP3 RImRNA was significantly higher in all TNFα-treated groups than control group(2 h:3.35 ± 1.97; 4 h:3.16 ± 1.35; 8 h:3.70 ± 1.76; 24 h:4.49±1.70; D:1 ±0.01; F =6.167,P <0.05).No difference was found among all TNFα-treated groups(P >0.05).No difference was found among S,TS,and control groups(S:1.53 ±0.79; TS:1.32 ± 0.38 ; P > 0.05).Conclusions IP3 RI was mainly distributed in cytoplasm of GMCs.TNFa could enhance the expression of IP3 RI protein and IP3 RI mRNA,which could be blocked by sanfingol,a PKCα inhibitor.It might be an important signal in the mechanisms of GFR decrease caused by TNFα in hepatorenal syndrome.
8.Analysis on second operation after laser in situ keratomileusis
International Eye Science 2015;(7):1293-1295
AlM:To observe clinical effects between the laser in situ keratomileusis ( LASlK ) surgery and the laser subepithelial keratomileusis ( LASEK ) surgery as the second operation after an unsuccessful LASlK surgery.METHODS:Forty-nine patients (98 eyes) with refractive regression after LASlK operation received the second surgery. All patients were divided into two groups:group A and B. Group A (48 eyes of 24 patients) received LASlK surgery and group B ( 50 eyes of 25 patients ) received LASEK surgery. lnspect the main parameters included visual acuity, refraction, corneal curvature, and the total value of high-aberration after 1wk, 1mo and 1a, t-test of groups was used as statistical analysis method.RESULTS: There was statistically significant (P<0. 05) between the two groups in visual acuity after 1wk. There was no statistically significant between the two groups in visual acuity after 1mo, and there was also no statistically significant between the two groups in visual acuity, average spherical equivalent refractive degree, average corneal curvature, and the total value of high-aberration after one year (P>0. 05). There developed one case of epithelium in growth after LASlK surgery, and one case of haze Ⅱ after LASEK surgery.CONCLUSlON: Both LASlK and LASEK surgery can obtain satisfactory therapeutic results after an unsuccessful LASlK surgery.

Objective To study the therapeutic effect of plasma exchange and plasma perfusion(PE+PP)on acute fatty liver of pregnancy.Methods Twenty-one patients with acute fatty liver of pregnancy were divided into two groups.In the treated group,the patients were treated with (PE+PP) on the basis of the conventional therapy,and the control group received the conventional therapy only?Liver function,kidney function and prothrombin activity(PTA) before treatment and 4 weeks,6 weeks after treatment were observed.Results After treatment with (PE+PA),the liver function,kidney function and PTA were ameliorated at 4 weeks and 6 weeks(P

Objective To investigate the effects of pulmonary arterial endothelium cells(PAEC) injuryed by tumor necrosis factor ? (TNF-?) on the proliferation of pulmonary arterial smooth muscle cells (PASMC) and the influence of heat stress response (HSR) on it .Methods Normal PAEC or PAEC endured with HSR were incubated with TNF-? at the concentrations of 500, 1000 and 2000u/ml in 1 hour, then cultured in DMEM without serum in 24 hours, the upper liquid was collected to prepare the endothelial cell-conditioned medium liquid (EC-CMⅠ or EC-CMⅡ ), in which PASMC were incubated in 24 hours as group Ⅰ or group Ⅱ respectively. The normal endothelial cell-conditioned medium liquid was also prepared to incubate PASMC in 24 hours as group Ⅲ.The PASMC were incubated without the endothelial cell-conditioned medium liquid as group Ⅳ.Flow cytometry was applied to determining the intracellular DNA content of the incubated PASMC. The fractions of different cytocycle phases were calculated according to the areas under the curves of DNA content.Results Compared with those of group Ⅳ, the percentage of PASMC in G0-G1 phases increased markedly ,and in S and G2-M phases decreased significantly in group Ⅲ (P
