Objective To investigate the effects and mechanism of different doses of rosuvastatin on expression of tissue factor(TF) in cultured human monocyte-macrophage cells which were induced by oxidized low density lipoprotein (ox-LDL).Methods The human monocyte-macrophage cells were divided into seven groups:control group,ox-LDL group,poly-insine monophosphate group,different doses of rosuvastatin group(0.01 μmol/L,0.1 μmol/L,1 μmol/L,5 μmol/L).The expression of LOX-1 mRNA and TF mRNA was assayed by RT-PCR.The enzyme-linked immunosorbent assay was performed to determine the protein concentration of TF.Results Effects of different doses of rosuvastatin on expressions of LOX-1mRNA,TF mRNA and TF in cultured human monocyte-macrophage cells induced by ox-LDL:comparison among seven groups,the difference was statistically significant (F =91.334,58.833,103.552,P <0.05).Compared with control group,the expressions of LOX-1 mRNA,TF mRNA and TF were increased in the ox-LDL group[(3.25156 ± 0.15772) vs (1 ±0) ;(2.522451 ±0.138967) vs (1 ±0) ;(207.7233± 1.154701)ng/L vs (184.8467 ± 0.871799)ng/L],and they were in a concentration-dependent manner (P < 0.05).Compared with the PolyⅠ group and the different doses of rosuvastatin group,the expressions of LOX-1 mRNA,TF mRNA and TF were in the ox-LDL group,and the different doses of rosuvastatin were decreased by dose-dependent manner.It was in a concentration dependent manner (P < 0.05).Different doses of rosuvastatin were compared between groups (between each group P < 0.05),the difference between each two groups was statistically significant (P < 0.05).Conclusions LOX-1 may be responsible for the expression of TF in Human monocyte-macrophage cells induced by ox-LDL.Rosuvastatin by dose dependent manner and by means of ox-LDL reduced monocyte-macrophage LOX-1 mRNA and TF mRNA expressions,which reduced expression of TF.

Objective To investigate the diagnostic value and clinical implications of low hemoglobin density(LHD%)in the pa-tients with cervical carcinoma complicating iron deficiency anemia(IDA).Methods The iron metabolism indexes and whole blood cell parameters were detected in 148 patients with cervical carcinomas.LHD% was calculated.The results were compared with that in the healthy group and the hysteromyoma complicating IDA group.Results LHD% was(63 ±30)% in the cervical carcinoma complicating IDA group and(32±15)% in the cervical carcinoma complicating iron deficient erythropoiesis(IDE)group,which were higher than(7±6)% in the healthy group,(22 ±21)% in the cervical carcinoma non-iron deficiency group and(16 ±10)% in the cervical carcinoma non-anemia group(P <0.05 ).And which had no statistical difference between the hysteromyoma complicating IDA group and the cervical carcinoma complicating IDA group(P >0.05 ).Conclusion The new RBC parameter LHD% has the reference value in the diagnosis of cervical carcinoma complicating IDA.The LHD% increase may prompt cervical carcinoma com-plicating IDA.

AIM: To decide the effect that selected siRNA degrades mRNA of IL-1? specifically and suppression of its expression after connected with target site with homology complementary sequence. METHODS: Synthesized DNA expression box aimed directly at target site through PCR reaction in vivo was purified, and transfected into lymphocytes stimulated by LPS. siRNA was transcribed by cellular endogenous RNA polymerase Ⅲ and then evoke the degradation of target mRNA. After 48 hours of transfection, the cell culture supernatant was collected and the concentration of IL-1? was assayed using ELISA. RESULTS: Compared with blank-control and negative-control, selected sequence decreased the expression of IL-1?. Rate of the suppression was about 15%. CONCLUSION: RNAi technology produces specific interference effect in mouse spleen lymphocytes in original culture and inhibits the excretion of IL-1?.

OBJECTIVE:To study the improvement effects of polydatin on renal fibrosis in rats and its mechanism. METH-ODS:50 rats was were randomly divided into sham operation group,model group,positive group(benazepril,5 mg/kg)and poly-datin high-dose and low-dose groups(100,50 mg/kg),with 10 rats in each group. Except for sham operation group,renal fibrosis model was induced by unilateral ureter obstruction. After modeling,administration groups were given relevant medicine intragastri-cally,and sham operation group and model group were given 0.5%sodium carboxymethyl cellulose solution once a day for consec-utive 4 weeks. The pathological change of renal tissue was scored. 24 h urinary protein and serum levels of urea nitrogen and creati-nine were determined,and the content of hydroxyproline,mRAN expression of TGF-β1 and FN were detected in renal tissue. RE-SULTS:Compared with sham operation group,pathological score,24 h urinary protein,serum levels of urea nitrogen and creati-nine,the content of hydroxyproline in renal tissue,mRNA expression of TGF-β1 and FN were all increased significantly (P<0.01). Compared with model group,24 h urinary protein,serum levels of urea nitrogen and creatinine and mRNA expression of FN in renal tissue decreased significantly in administation groups;the pathology scores,the content of hydroxyproline in renal tis-sue and mRNA expression of TGF-β1 of positive group and polydatin high-dose group were all decreased significantly(P<0.05 or P<0.01). CONCLUSIONS:Polydatin can prevent kidney fibrosis induced by unilateral ureteral obstruction,the mechanism of which may be associated with the mRNA expression down-regulation of TGF-β1 and FN in renal tissue.
