Objective To study the relation between the effect of Curcumin on the proliferation and activation of hepatic stellate cells(HSC)and the expression of the peroxisome proliferator-activated receptor?(PPAR?).Methods The rat HSC was isolated from SD rats through in situ perfusion of liver with Pronase E and density-gradient centrifugation with Nycodenz.The subcultured cells were treated with corresponding compound.The inhibition effect on HSC proliferation was determined by MTT colorimetry.The total RNA was extracted by TRizol reagent,and the gene expression level of PPAR? and smooth muscle actin (?-SMA)were determined by semi-quantitative RT-PCR.The total cellular proteins were extracted and separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis,and the protein level of ?-SMA was determined by Western blotting.Results The MTT analysis results showed that Curcumin inhibited HSC proliferation between 10 and 50 ?mol/L in a dose-dependent manner.In the Day 1,4,7 of primary HSC and passaged HSC,the expression of PPAR? mRNA decreased with HSC activation extent;Curcumin could up-regulate the expression level of PPAR?.Curcumin suppressed the expression of ?-SMA not only at the gene level but also at the translation level.But all these effects of Curcumin on HSC could be blocked by the PPAR? specific antagonist GW9662.Conclusion The effect of Curcumin on HSC cell proliferation and activation is through the up-regulation of PPAR? signal.

Aim To study the effect of Curcumin on the apoptosis of hepatic stellate cells (HSC), and the correlation between the effect and peroxisome proliferator-activated receptor ?(PPAR?) signal.Methods The HSC was isolated from normal SD rats through in situ perfusion of liver with protease E and density-gradient centrifugation with Nycodenz.The subcultured cells were treated with corresponding compounds. Cell apoptosis was detected by Hoechst 33258 staining. PPAR? subcellular distribution was detected by immunofluorescent staining. Total RNA, total protein and nuclear protein were extracted respectively, target gene and protein levels were determined by semi-quantitative RT-PCR or Western blot.Results There was nearly no apoptosis in activated HSC. Curcumin treatment induced the apoptosis of HSC, enhancing PPAR? nuclear translocation/redistribution.At the transcription and translation level,curcumin upregulated nuclear PPAR? expression, inhibited anti-apoptotic Bcl-2 expression, and promoted pro-apoptotic Bax expression; but all these effects could be reversed by PPAR? antagonist GW9662.Conclusions Curcumin induces HSC apoptosis by enhancing PPAR? expression and nuclear translocation/redistribution.

Objective: To compare the efficacy of paroxetine and amitriptyline in the treatment of primary fibromyalgia syndrome.Methods:46 out- and in-patients with primary fibromyalgia syndrome were randomized to two groups and treated respectively with amitriptyline 25mg~50mg per day and paroxetine 10mg~20mg per day. The Visual analogue scales(VAS) was used to evaluate the efficacy and adverse effects were recorded at baseline, month 1 and month 3.Results:In both groups pain was alleviated with statistical significance after 1 month of treatment. However the efficacy of amitriptyline and paroxetine was not statistically significant at different time points. The occurrence of adverse effects in paroxetine group was less than in amitriptyline group and the difference was statistically significant, especially dry mouth and palpitation.Conclusion:Paroxetine is as effective as amitriptyline in the treatment of primary fibromyalgia syndrome but with a better safety profile.

Objective To explore the clinical value of measuring myoglobin (MYO) for the early diagnosis of ACS and monitoring the effect of thrombolysis. Methods MYO and cTnT, CK、CK-MB were measured. The sensitivity, specificity, positive predicting value and negative predicting value of cTnT and CK-MB at different time points were studied. And the correlation was investigated between the MYO plasma level and the severity of coronary artery lesion according to coronary arteriongraphy. The changes of MYO level with thrombolysis were also observed.
