Translational medicine is a novel concept about combination of basic research and clinical application. The aim of translational medicine is to realize the translation of basic research into clinical practice. microRNAs (miRNAs) are non-coding single-stranded RNAs with 21-25 nucleotides in length as newly discovered factors in regulating gene expression. Recently, the key regulatory role of miRNA in the cardiovascular system has been elucidated and amount of remarkable results has been achieved, particularly in the regulation of cardiac arrhythmias. A series of studies demonstrate that miRNAs are involved in the regulation of expression of a variety of proteins associated with cardiac electrical activity, and are the potential targets of occurrence of cardiac arrhythmias and anti-arrhythmic drugs. miRNAs as a therapeutic target regulate the stability of mRNAs of target genes or play an inhibitory role in the translation process. Stability of the corresponding miRNA expression levels in the target organ may be a new approach for the disease therapy. Regarding the dysfunction of miRNA, we employed miRNA re-expression strategy and anti-miRNA strategy to correct target protein function and provide a new entry for the therapy of arrhythmia. With the technology of miRNA mimics and antagomirs, miRNAs are expected to treat various cardiovascular diseases and will provide a fresh impetus to achieve transform medicine.

Objective To investigate the influence on the behavior of withdrawal and relapse after deep brain stimulation of bilateral nucleus accumbens in morphine-dependent rats. Methods The rats with a strong unconditioned preference were discarded in preconditioning test, the selected rats were distributed into five groups randomly. After operation,morphine hydrochloride was injected subcutaneously into SD rats for 12 days (once every day,initial 5 mg/kg,increasing by 5 mg/kg per time,stable in 20 mg/kg ). A modified electrical circuit was used to procedure the DBS,the parameter was 130 Hz,150 A,60 s,l h/d,14 d. CPP test was used to exam the effect of DBS. A minor morphine dose (3 mg/kg) was injected to induce the behavior of relapse, and CPP was tested again after 24 h. Two-way ANOVA was performed on the data with Bonferroni posttest. Result ①After CPP training,CPP score of group morphine, morphine + sham and morphine + DBS was ( 155. 87 ± 20. 45 ) s, (107.33 ± 18.10)s,(135.45 ±22.09)s,and had significant difference with group of control( ( -70.34 ± 15.40) s)(t = 9.45,P<0.01; t = 6.94,P<0.01;t = 8.04,P<0.01).②After 7 days' DBS,the CPP score in group of morphine + DBS reduced significantly compared to group of morphine( t = 4.21, P<0.01) and morphine + sham( t=1.10, P<0.05).0n the 14th day,there was more pronounced reduction ( t = 5. 15, P<0.01; t = 3.92, P< 0.01). ③ 24 hours after the minor morphine dose was injected,the CPP score in morphine + DBS didn't increase significantly, and had significant difference with group of morphine ( t = 4.04, P<0.01) and morphine + sham ( t= 4. 13, P<0.01). Conclusion DBS bilateral nucleus accumbens in morphine-dependent rats can interfere the behavior of morphine-induced CPP and relapse.

Objective To investigate the effects of penehyclidine hydrochloride (PHCD) pretreatment on NF-κB mRNA expression and SOD activity in lung tissues in rats with acute lung injury (ALI) induced by LPS.Methods Thirty-two male SD rats, 2 months old, weighing 230-280 g, were randomly divided into 4 groups (n=8 each): control group (group C), ALI group, low dose PHCD group (group LP) and high dose PHCD group (group HP). ALI was induced by intravenous LPS 5 mg/kg via tail vein. Group LP and HP received intraperitoneal PHCD 0. 3 and 1 mg/kg respectively 30 min before LPS administration. The rats were killed at 6 h after LPS administration. The lungs were removed immediately for determination of W/D lung weight ratio, lung water content, NF-κB mRNA expression, TNF-α and MDA content, and SOD activity and microscopic examination. Results NF-κB mRNA expression, TNF-α and MDA content, W/D lung weight ratio and lung water content were significantly higher, while SOD activity was significantly lower in group ALI, LP and HP than in group C (P < 0.05). NF-κB mRNA expression, TNF-α and MDA content, W/D lung weight ratio and lung water content were significantly lower, while SOD activity was significantly higher in group LP and HP than in group ALI and HP than in group LP (P < 0.05). The LPS-induced changes were mitigated by pretreatment with low and high doses of PHCD in group LP and HP.Conclusion Pretreatment with PHCD attenuates LPS-induced ALI by downregulating NF-κB mRNA expression, decreasing local inflammatory response and enhancing anti-oxidant activity.

Objective To investigate the effects of Triptolide on apoptosis of cultured rat mesangial cells treated by TGF-β1 and the role of Smac in this process. Methods The mesangial cells were pre-treated with different concentrations of Triptolide for 24 hours, then stimulated with TGF-β1 for 24 hours. Apoptotic cells were detected by TUNEL assay. Smac transcription level was determined by Real time-PCR analyses. Smac expression level was assessed using Western blot anal-yses. Localization of Smac was shown by confocal fluorescence microscopy. Results Compared with control group, TGF-β1 inhibited apoptosis and Smac transcription and expression in rat mesangial cells. By contrast, Triptolide promoted mesangial cells apoptosis. In Triptolide groups, Smac mRNA and protein levels were up-regulated. Additionally, in normal and TGF-β1 groups Smac protein was mainly localized in mitochondriawhile in Triptolide groupit was mainly localized in cytoplasm and nucleus with increased fluorescence intensity. Conclusion Triptolide could promote the effect that TGF-β1 inhibited apop-tosis of mesangial cells, through both up-regulation the expression of Smac and stimulating it translocation from mitochon-dria to cytoplasm and nucleus.
