Objective To investigate the effect of tumor necrosis factor-α (TNF-α) on intracellular calcium concentration ([Ca2 +] i) and the contraction of glomerular mesangial cells (GMCs),and prove that hypercontractility of GMCs induced by TNF-α in hepatorenal syndrome(HRS) was connected with inositol 1,4,5-trisphophate receptors (IP3Rs).Methods GMCs were divided into TNF-α-treated 0 h,4h,and 24 h groups.Another 3 groups were blocked by 2-APB.The effect of TNF-α on [Ca2 +] i was identified and observed whether it could be blocked by 2-APB.Contraction of GMCs was determined by accessing the surface area of cells before and after contraction.Results TNF-α significantly increased ET-induced calcium release,in that we found higher [Ca2 +] i after stimulated by ET in TNF-α-treated 4 h group and 24 h group[4 h:(648.08 ±267.11) nmol/L; 24 h:(879.30 ±-260.29) nmol/L; 0 h:(619.93 ±258.94)nmol/L,F =5.486,4 h vs 0 h:P ＜ 0.05 ; 24 h vs 0 h:P ＜ 0.05 ;24 h vs 4 h:P ＞ 0.05].This phenomenon can be totally blocked by 2-APB in all groups.The change in planar surface area in response to ET was slightly in control cells but significantly enhanced in TNF-α-treated cells [4 h:(2198 ± 340)μm2; 24h:(2260±553)μm2; 0 h:(2436±474)μm2,F =4.001,4 h vs0 h:P ＜0.05; 24 h vs0 h:P ＜0.05;24 h vs 4 h:P ＞ 0.05].Conclusion TNF-α can enhance ET-induced sarcoplasmic reticulum Ca2 + release and increase the contractile responses of GMCs to ET,which is associated with IP3Rs.TNF-α is responsible for hyperconstractility of glomeruli in HRS.

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
