Objective To study the role of hydrogen sulfide (H2S) in the effect of SB203580 on proliferation and apoptosis of hepatic stellate cells and the effects of H2S on expressions of collagenⅠand collagenⅢmRNA in hepatic stel-late cells. Methods There were five groups of HSC-T6 cells in this study including control group (DMEM medium contain-ing10%fetal bovine serum), dimethyl sulfoxide (DMSO) group, sodium hydrosulfide (NaHS)group,SB203580 (SB)group and SB+NaHS group. MTT method was used to detect the cell proliferation and inhibition rate of HSC-T6 cells treated by SB203580 and H2S. The apoptotic rate of HSC-T6 cells was detected by flow cytometry with annexin V-FITC/PI double staining. RT-PCR was used to detect the expressions of collagenⅠand collagenⅢmRNA in HSC-T6. Results The apop-totic rate of HSC-T6 cells was significantly higher in SB group and SB+NaHS group than that of control group, and the rate was significantly higher in SB+NaHS group than that of SB group (P<0.05). There was no significant difference in the apop-totic rate of HSC-T6 cells between DMSO and NaHS groups than that of control group. The expressions of collagenⅠand col-lagenⅢmRNA were found in five groups of cells. There was a higher expression of collagenⅠand collagenⅢmRNA in NaHS group than that of control group (P<0.05). The expressions of collagenⅠand collagenⅢmRNA were significantly lower in SB group and SB+NaHS group than those of control group and NaHS group (P<0.05). Conclusion H2S activated P38MAPK signal pathway. And P38MAPK was specifically blocked by SB203580 in HSC-T6 cells, which inhibited the cell proliferation stimulated by H2S and promoted the apoptosis.

Objective To explore the relationship between receptor of advanced glycaton end products(RAGE)gene Gly82Ser polymorphism and patients with transient ischemia attack(TIA).Methods The Gly82Ser gene at the position of RAGE gene exon 3 was identified by a polymerase chain reaction- restriction fragment length polymorphism(PCR-RFLP)method in 70 cases of TIA & Diabetes(DM), 60 of simply TIA and 66 healthy control subjects.Results The genotypes of RAGE gene Gly82Ser identified were GG, GS and SS.The frequencies of RAGE gene Gly82Ser GS heterozygous genotype of TIA & DM and control were respectively 62.9% and 43.9%, significantly higher in TIA & DM patients than in control subjects(OR 2.036, 95% CI 1.021--4.062, P=0.042), however no significant difference was found between simply TIA and control(53.3% vs 43.9%, OR 1.299,95% CI O.644--2.618, P=0.465). Significant difference of the frequency of S allele was found neither between TIA & control and control(being 34.3% and 26.5%, respectively, OR 1.446,95% CI 0.859--2.434, P=0.164), nor between simple TIA and control(28.3% vs 26.5%, OR 1.096,95%CI 0.630--1.907, P=0.746).Conclusions RAGE gene Gly82Ser GS heterozygous genotype may be associated with TIA & DM patients.RAGE gene Gly82Ser polymorphism is a risky factor for TIA & DM patients, but not for TIA patients.

The study is aimed to ensure the quality and safety of medicinal plants by using ITS2 DNA barcode technology to identify Corydalis boweri, Meconopsis horridula and their close related species. The DNA of 13 herb samples including C. boweri and M. horridula from Lhasa of Tibet was extracted, ITS PCR were amplified and sequenced. Both assembled and web downloaded 71 ITS2 sequences were removed of 5. 8S and 28S. Multiple sequence alignment was completed and the intraspecific and interspecific genetic distances were calculated by MEGA 5.0, while the neighbor-joining phylogenetic trees were constructed. We also predicted the ITS2 secondary structure of C. boweri, M. horridula and their close related species. The results showed that ITS2 as DNA barcode was able to identify C. boweri, M. horridula as well as well as their close related species effectively. The established based on ITS2 barcode method provides the regular and safe detection technology for identification of C. boweri, M. horridula and their close related species, adulterants and counterfeits, in order to ensure their quality control, safe medication, reasonable development and utilization.

BACKGROUNDThe association between vulnerability of plaque assessed with intravascular ultrasound (IVUS) and plasma levels of fibrinolytic biomarkers was determined in patients with acute coronary syndrome (ACS). However, few data are available on the relationship between the levels of tissue type plasminogen activator (t-PA) and virtual histological intravascular ultrasound (VH-IVUS) signs of plaque instability.
METHODSEighty-nine patients with ACS were enrolled in the study. Blood was collected to measure t-PA levels by liquid phase bead flow cytometry. Eighty-nine nonbifurcate lesions (identified by coronary angiography and ECG) were investigated using IVUS before catheterization. IVUS radiofrequency data obtained with a 20 MHz catheter were analyzed with IVUS virtual histological software. The areas of plaque and media were calculated and lesions were classified into two groups: VH-IVUS derived thin cap fibroatheroma (VH-TCFA) and non-VH-TCFA plaque.
RESULTSPlasma t-PA level in the patients with TCFA was significantly lower than that with non-TCFA ((1489+/-715) pg/ml vs (2163+/-1004) pg/ml). Decreased plasma levels of t-PA were associated with plaque vulnerability. Plasma levels of t-PA correlated negatively with plaque plus media and necrotic core in plaque in patients with ACS.
CONCLUSIONSt-PA is an independent risk factor and a powerful predictor of vulnerable plaques. Decreased levels of t-PA may reflect instability of atherosclerotic plaques and might therefore serve as noninvasive determinants of those at high risk for consequent adverse events.

OBJECTIVETo investigate the effects of overexpression of second mitochondria-derived activator of caspases (Smac) gene on apoptosis of gastric cancer cells.
METHODSUnder the induction of liposome, MKN-45 cells were transfected by Smac gene and incubated with G418 for subclone selection. Reverse transcriptase-polymerase chain reaction and Western blot were used to determine cellular Smac gene expression. After induction of apoptosis by mitomycin (MMC), cell viabilities were analyzed using trypan blue stain. Apoptosis was measured by electronic microscopy, acridine orange-ethidium bromide fluorescent staining and in situ terminally labelled transferase technique (TUNEL). Western blot and colorimetry were used to assess cellular caspase-3 expression and its activity.
RESULTSThe Smac mRNA and protein levels in MKN-45/Smac subclone cells (subclone consistently expressing Smac gene) were significantly higher than those in MKN-45 (P < 0.01). When compared with those in MKN-45, cell viabilities of MKN-45/Smac were reduced by 10.0% to 30.8% (P < 0.01), after treatment with 10 microg/ml MMC for 6 to 24 hours. Some of the MKN-45/Smac cells showed characteristic morphologic changes of apoptosis, their apoptotic rate being increased by 21.2% (P < 0.01). After treatment with MMC, caspase-3 expression and its activity in MKN-45/Smac cells were significantly higher than those in MKN-45 (P < 0.01).
CONCLUSIONSOverexpression of Smac in gastric cancer cell line significantly improves expression and activity levels of caspase-3 after induction by MMC. Such apoptosis-inducing effect establishes a novel strategy for regulating the apoptosis activity of gastric cancer.
