ABSTRACT
Objective To investigate the effect of triptolide (TP) on proliferation and apoptosis of cyst-lining epithelial cells with autosomal dominant polycystic kidney disease ( ADPKD). Methods Primary cultured cyst-lining epithelial cells were treated with TP at different concentrations for 12 h,24 h,48 h and 72 h, respectively.The proliferation activity of the cells was evaluated by Brdu assay. The cell cycle distribution was determined by flow cytometry. The apoptotic and apoptotic ratio were determined by FITC-AnnexinV binding/ PI. The morphological changes of cyst-lining epithelial cells were observed under transmission electron microscope. Results TP significantly inhibited the proliferation of cyst-lining epithelial cells and induced apoptosis in a dose- (10-40 ng?mL-1 )and time-dependent(12-48 h) manner. Typical ultrastructural changes of apoptotic cells were observed under electron microscope. Conclusion TP significantly inhibited the proliferation of cyst-lining epithelial cells and induced the apoptosis of cyst-lining epithelial cells, thus inhibited cyst forming and delayed cyst developing. The mechanism may involve several targets and pathways.
ABSTRACT
Objective To ivevstigate the feasibility, the effects and the therapy of peritoneal dialysis(PD) on severe acute pancreatitis (SAP). Method From January,2001 to Jaly 2006,48 patients of SAP were divided randomly into PD group and non-PD group in Qingzhou hospital. Both groups were treated by the conventional mode of therapy. In PD group , using the concept of PD,24 patients of SAP were treated with PD and NPD group were treated only with common therapy. The release time of abdominal pain and distention, CT scores, APACHE II scores, the time of hospital stay, cost of treatment in hospital, operative rate and rate of complications and recovered rate of the two groups were compared. Simutaneously. the concentration of serum and fluid filtrated inflammatory cytokines TNFα,IL-6,IL-8,IL-10 and CRP were also determined pro and post the therapy. Results In the PD and NPD group, the duration for disappear-ance of abdominal pain and tenderness,and amelioration for abdominal distension was (19.70 ±7.32) hvs. (81.46±36.68) h and (23.16±6.95) h vs.(78.19± 29.26) h;So that the PD group was precede to that in NPD group ( P < 0.05). The concentration of serum and fluid filtrated pro-inflammatory cytokines TNFα, IL-6, IL-8 and CRP at each observation points after PD was decreased significantly (P <0.05) in the PD group. But the concentration of the serum and fluid filtrated anti-inflammatory cytokines IL-10 was increased significantly (P < 0.05) as compared with that of the NPD group. Conclusions Through PD, the imbalance of pro-inflammatory and anti-inflammatory cytokines has been corrected at early stage of SAP. But the PD is method that is easy, quick, small wou-ndell,few complicated and effective in patients with early-phase SAP, and will be of great value in wide application and further study.
ABSTRACT
Objective To invest the effect of minimal inflammation on patients with maintenance hemodialysis(MHD) and the intervention effect of ftuvastatin.Methods Blood indicators such as PA,ALB and BUN,Cr,TC,TG,HDL-C,LDL-C,Lp(a),SF,hs-CRP,IL-6 and TNF-α were detected at the first day of the study and six months later in all patients.Patients were divided into inflammation group(CRP≥8 mg/L) and non-inflammation group(CRP<8 mg/L) according to CRP levels.Only inflammation group used fluvastatin.Two groups were observed for six months.Results The level of hs-CRP,IL-6,TNF-α,TG,Lp(a),SF in MHD patients was obviously higher than the normal control group.The level of ALB was obviously lower than the normal control group.The angiocardiopathy incidence of inflammation group was obviously higher than that of the non-inflammation.The more obvious of minimal inflammation,the more significant of lipid metabolism disturbance and malnutrition.Hs-CRP,IL-6,TG,TC,LDL-C and Lp(a) of inflammation group decreased obviously(P<0.01 or P<0.05).ALB、HDL-C increased obviously(P<0.05).Indicators of the non-inflammation had no statistical difference after therapy.Conclusions Patients with MHD generally have minimal inflammation and malnutrition.Minimal inflammation has important effect on the angiocardiopathyincidence,lipid metabolism disturbance and malnutrition.Fluvastatin not only could regulate lipid metabolism but also improve the minimal inflammation of patients with MHD.Early detection and therapy of minimal inflammation has important significance on improving prognosis of patients with MHD.
ABSTRACT
Objective To investigate the significance of renal tubular dysfunction in patients with refractoriness nephrotic syndrome(RNS)and the effect of interference treatment of Valsartan (VAL).Methods 79 cases of RNS and 68 healthy controls were recruited into the study. The 79 patients of RNS were divided randomly into the VAL group and the dipyridam group. On the basis of routine therapy, the VAL group was given VAL(80mg/d),and the dipyridam group taken dipyridam (150mg/d)orally for 12 weeks The glomerular tubular function(u-RBP,α1-MG,β2-MG,mAlb,NAG)were detected and the pathologic changes of tubukinterstitium were observed by using the methods of ELISA, biochemistry and scoring of the pathologic damage of tubulointerstitium before and after 12 weeks of VAL treatment in all of the cases. Results Urinary RBP,α1-MG,β2-MG,mAlb and NAG in all patients with RNS was evidently higher than that in healthy controls(P＜0.01).Those had positive correlations with damages of tubulointerstitium(r=0.436,0.626,0.499,0.668,0.657,P＜0.01).The interference outcome displayed that the excretion rates of urinary series of protein after oral use VAL in treatment group were markedly lower, while the control group had no distinct change. Conclusion There were various injury of tubulointerstitium and the disfiguration of renal tubular function in all cases with RNS. Damages of renal tubular function had positive correlation with tubulointemtitium injury and renal globular injury. Interference treatment with ARB in patients with RNS could improve renal tubular function, which is of great significance in delaying the progress of RNS.
