BACKGROUND: siRNA transfection is a key step in RNA interference. The methods of cardiomyocytes transfection were most use of plasmids as vector to transfect long-chain shRNA. However, the processes were complex. It was a simple efficient and low-toxic method that liposomes-mediatad chernosynthesis siRNA transfection. It was useful for expanding RNA interference application.OBJECTIVE: To choice the optimal concentration of Iiposomes-mediated chemosynthesis siRNA transfection, and to discover a simple efficient RNA interference application.METHODS: CY3-Negative siRNA was mediated by lipid-besed agent siPORT~(TM) NeoFX~(TM) to transfect cardiomyocytes. A blank control group was set. After 24 hours, the transfection efficiency and apoptotic rate were evaluated by fluorescent microscope and flow cytometer to select an optimal concentration. Based the best concentration, siRNA PHB was transfected to cerdiomyocytes. 48 hours later, the expression of PHB was tested.RESULTS AND CONCLUSION: With the increased concentration of CY3-Negative siRNA, the number of cells emitted red fluorescence grew under fluorescence microscope, and the transfection efficiency was also increased (P＜0.05). The best concentration was 30 nmol/L (P＜0.05). There was no significant difference in apoptotic rate between transfected groups and the control group (P ＞ 0.05). The PHB expression of cardiomyocytes transfected siRNA PHB was dropped by 74.11% on average (P＜0.05). The results indicated that lipid based agent siPORT~(TM) NeoFX~(TM) was suitable to transfect chemosynthesis siRNA to cardiomyocytes, and the best transfection concentration of siRNA was 30 nmol/L.

BACKGROUND: Hibiscus Mutabilis L. Is a very effective Chinese traditional herb for non-specific inflammation in the clinic adopted by Professor Wei Zhixin, the eminent expert in Traumatology Department in China, lasting for near 60 years. In order to explain its pharmaceutical mechanism, the research of Hibiscus Mutabilis L. Was carried on in the model of ischemic reperfusion injury to explain its mechanism on anti-inflammation.OBJECTIVE: To observe the protection of the effective fraction of Hibiscus Mutabilis L. (MFR) on renal ischemic reperfusion injury in rats to probe into the mechanism of MFR on anti-inflammation.DESIGN: Randomized and controlled study on experimental animal.SETTING: A Municipal Institute of Traumatology and Orthopedic Department.MATERIALS: The experiment was performed in the Key Experiment Room (Institute of Traumatology and Orthopedic Department, Shanghai) of State Administration of Traditional Chinese Medicine, in which, 55 male Wistar rats were employed.METHODS: The rat model of renal ischemic reperfusion was adopted and MFR was applied for gastric perfusion to determine serum blood urea nitrogen(BUN) and serum creatinine(Scr) and the level of interleukin-1 (IL-1).MAIN OUTCOME MEASURES: ① Changes in serum BUN and Scr; ②Effect of MFR on level of serum IL-1.RESULTS: After MFR treatment, the renal function was improved remarkably after ischemic reperfusion in rats. In sham-operation group, serun BUN was (6.72 ± 1.30) mmol/L and serum Scr was (38.40 ± 6.23) μmol/L. In 24hours of reperfusion after one-hour ischemia, BUN was(60. 72±4.64)mmol/L in the control and(47.34 ± 8.32) mmol/L in the MFR treatment group, and the significant difference presented between two groups(t=2.562, P ＜ 0.05) .Serum Scr was(347.95±95) μmol/L and(518.20 ± 41.15) μmol/L in the treatment group and the control respectively, indicating significant difference ( t = 3.69, P ＜ 0.01 ) . Concerning to the effect on IL-1, in 1 hour of reperfusion after 1 hour renal ischemia,IL-1 was( 122.79 ±27.56) ng/L in the MER treatment group,(180. 28 ±33. 15) ng/L in the control group, indicating that IL-1 level in the treatment group was remarkably superior to that in the control group(t = 2.98, P ＜ 0.05). In 3 hours of reperfusion after 1 hour ischemia, level of IL-1 in the treatment group and control group was(15.58±8.59) ng/L and (34. 13±± 10. 02) ng/L respectively, indicating significant difference( t = 3.14, P＜ 0.05).CONCLUSION: MFR provides protection on renal ischemic reperfusion injury, which probably is related to its inhibition on IL-1 formation.

Objective To investigate the anti-apoptotic mechanism of tanshinone ⅡA and the function of prohibitin(PHB)onmyocardial cells apoptosis induced by hydrogen peroxide(H2O2).Methods Myocardial cells were primary culturedneonate rat were cultured in medium with 200 μmol/L H2O2,and the medium was supplemented with tanshinone ⅡA(1 × 10-4 mol/L)in advance for 24 h.PHB in myocardial cells was knocked down by RNA interference,and theexpression level of PHB was determined by Western blotting analysis.Flow cytometric analysis was used to detectapoptosis rate,intracellular calcium concentration([Ca2+]i),and mitochondrial membrane potential(MMP).ResultsH2O2-mediated cell apoptosis resulted in activation of PHB,increasing of[Ca2+]i,and decreasing of MMP.TanshinoneⅡA profoundly inhibited myocardial cell apoptosis induced by H2O2,decreased[Ca2+]i,and increased MMP.Specificsilence of PHB by siRNA down-regulated the expression level of PHB,increased apoptosis rate and[Ca2+]i,and decreasedMMP.Conclusion The results demonstrate that tanshinone ⅡA could attenuate apoptosis induced by H2O2,and theactivation of PHB induced by H2O2 is the major regulatory pathway of cyto-protective gene expression against oxidativestress.

Object To study the effect of puerarin on the expression of inflammatory factors and miR-155-3p in human umbilical vein endothelial cells ( HUVEC) induced by visfatin.Methods The HUVEC cell injury model was es-tablished with visfatin.Cell proliferation was measured by MTT assay.Cell apoptosis was detected by flow cytometry.The level of CRP and NF-κB was detected by ELISA, and the expression of miR-155-3p was detected by RT-PCR.The expres-sion of myeloid differentiation factor 88 ( MyD88) was identified by western blotting.Results Visfatin induced cell prolif-eration and inhibited apoptosis in HUVEC, meanwhile the expressions of both CRP and NF-κB were significantly increased, compared with that of the control group (P<0.01).Puerarin at moderate and high concentrations obviously reduced the HUVEC injury induced by visfatin, mainly through down-regulating the expression of CRP and NF-κB, as well as up-regu-lating the level of miR-155-3p in the HUVEC.MiR-155-3p mimic markedly decreased the level of MyD88, CRP and NF-κB in the HUVEC induced by visfatin (P<0.05).Conclusions Pueprarin obviously alleviates HUVEC injury induced by visfatin, probably related to down-regulating the level of MyD88, CRP, NF-κB, and up-regulating the expression of miR-155-3p in HUVEC.

Objective To investigate the relation between a set of single nucleotide polymorphisms (SNP) in core gene of HBV in chronic hepatitis B patients and HBV DNA levels. Methods PCR restriction fragment length polymorphism(PCR-RFLP) assay and restriction enzyme Tsp509I were adopted to determine HBV SNP in HBV core gene. Nucleotide sequences of core gene were determined using the dideoxy chain termination method. HBV DNA levels were quantitated with real-time PCR. Results Five typical RFLP patterns, RFLP-C, RFLP-D, RFLP-E, RFLP-G and RFLP-C/G mixture were found and the distribution of HBV RFLP patterns was as follows: C, 61. 5% ; D, 2. 6% ; E, 9.6%; G, 16.7%; C/G mixture, 9.6%. Five SNPs, A165T, A336C, A336T, T337C and T385C, were found to be associated with RFLP patterns change and only SNP A336C or A336T caused the substitution of Glu-83 with Asp in HBcAg. The serum HBV DNA levels in RFLP-C group were higher than that in RFLP-G (P =0. 02) and RFLP-C/G group(P = 0. 006) , respectively, furthermore, the positive rate of serum ALT in RFLP-C/G group was lower than that in RFLP-C, RFLP-E and RFLP-G group, respectively. Under the condition of HBeAg-positive, the serum HBV DNA levels in RFLP-C group were higher than that in RFLP-G (P = 0. 015) and RFLP-C/G group(P =0.008) , respectively. Conclusion PCR-RFLP used in this study can be adopted to determine HBV SNPs, not genotypes in Chinese patients with chronic hepatitis B. The serum HBV DNA level in RFLP-C group higher than that in RFLP-G or RFLP-C/G group maybe associated with amino acid mutation, Glu83 Asp.
