Whether surfactant protein B (SP-B)-18A/C and 1580C/T polymorphism were associated with susceptibility to chronic obstructive pulmonary disease (COPD) in Chinese Han population was investigated. After genomic DNA was isolated from blood of COPD smokers and control smokers, the genotypes of SP-B-18A/C and SP-B1580C/T polymorphism loci were determined by polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP) respectively. The results showed that there was significant difference in genotypes distribution frequency of SP-B1580C/T polymorphism locus between COPD smokers and control smokers. C-->T mutation rate (including TT homozygote and CT heterozygote) in COPD smokers was higher than in control smokers (57.9% vs 41.7%, chi2 = 4.93, P<0.05), whereas there was no significant difference in genotypes distribution frequency of SP-B1580-18A/C locus between COPD smokers and control smokers. The allele frequency (29.1%) of SP-B1580-18A/C locus is lower than T allele (70.9%) in Chinese Han Population, and the distribution was different from that in Mexican, in which, the A and T allele frequencies were 85% and 15% respectively. It was concluded that SP-B1580 T allele was probably associated with increased susceptibility to COPD in Chinese Han population; The polymorphism of SP-B-18A/C locus maybe varied with race.

Objective　To evaluate the role of transfected angiotensinⅡ(Ang Ⅱ) receptor AT1 anti-sense nucleotide (AT1A) in the expression of subtypes of AngⅡ receptor mRNA, synthesis of protein and nucleic acid in cardiomyocytes. Methods　AT1 cDNA sequence (476 bp) was cloned with RT-PCR and reversely inserted into PcDNA3.1 (5.4 kb) to construct an intact plasmid containing AT1A (PAT1A). The plasmid was then transfected into the cultured cardiomyocytes and identified with RT-PCR and Western blot. The synthesis of protein and nucleic acid identified by 3H-Leu and 3H-TdR incorporation, and expressions of AT1 and AT2 mRNA by RT-PCR, were compared between transfected and nontransfected cardiomyocytes after being stimulated with 10-7 mol/L AngⅡ for 24 h. Results　The plasmid PAT1A were successfully constructed. The AT1 mRNA and its protein were expressed significantly less in the transfected cardiomyocytes than in the control (P<0.01). In the transfected cardiomyocytes, AT1 mRNA expression was markedly decreased, but that of AT2 mRNA obviously increased (P<0.01) when compared with the nontransfected cardiomyocytes after stimulation for 24 h with AngⅡ 10-7 mol/L; no significant difference was found in 3H-Leu and 3H-TdR incorporation between them. Conclusion　After the cardiomyocytes was tranfected with AT1A, the expression of AT1 mRNA was markedly suppressed，while AT2 mRNA up-regulated at the same time. Our results indicate that AT1A blocking can not effectively interrupt the Ang Ⅱ-induced synthesis of the protein and nucleic acid in cardiomyocytes.

AIM: To investigate the contribution of diazoxide,an opener of mitochondrial ATP-sensitive K+ channel(MitoKATP),and mitochondrial membrane potential(??m) to change of H2O2 in rat pulmonary artery smooth muscle cells(PASMCs) and to unbalance between cell proliferation and apoptosis of PASMCs induced by hypoxia.METHODS: The rat PASMCs were isolated from fresh normal lung tissues and cultured,which were divided into 6 groups,as follows: ① control group;② diazoxide group;③ 5-HD group;④chronic hypoxia group;⑤ chronic hypoxia+diazoxide group;⑥ chronic hypoxia +5-HD group.The relative change in mitochondrial potential was detected with rhodamine fluorescence(R-123) technique.The level of H2O2 in rat PASMCs was detected with chemiluminescence method.The proliferation of rat PASMCs was examined by cell cycle analysis and MTT colorimetric assay.RESULTS: After exposed to diazoxide for 24 h,the intensity of R-123 fluorescence,the level of H2O2 and the A value in normoxic rat PASMCs were significantly increased,and the apoptosis of rat PASMCs was significantly decreased as compared with control group(P

BACKGROUND:Basic fibroblast growth factor (bFGF) plays an important role in the ligament tissue healing process, and bone marrow mesenchymal stem cel s transfected with growth factors can be used as seed cel s in ligament tissue engineering.
OBJECTIVE:To observe biological effect of bone marrow mesenchymal stem cel s transfected with recombinant adenovirus vectors carrying bFGF in three-dimensional co-culture with ligament fibroblasts.
METHODS:Passage 3 bone marrow mesenchymal stem cel s were divided into three groups:control group, Ad-EGFP group and Ad-bFGF group. Under a phase contrast microscope, the changes in cel morphology were observed and the rate of transfection was analyzed by flow cytometry. Proliferation of bone marrow mesenchymal stem cel s and ligament fibroblasts was analyzed by MTS, the expression of bFGF protein in bone marrow mesenchymal stem cel s was determined by ELISA. Scleraxis, col agen type I, col agen type III, decorin and cartilage oligomeric matrix protein levels were detected in BMSCs and ligament fibroblasts using real-time fluorescent quantitative PCR.
RESULTS AND CONCLUSION:Recombinant adenovirus-mediated bFGF gene could transfect bone marrow mesenchymal stem cel s efficiently. After co-culture for 3, 6 days, compared with the control group and Ad-EGFP group, in the Ad-bFGF group, the proliferation ability of bone marrow mesenchymal stem cel s and ligament fibroblasts was enhanced (P<0.01), the expression of bFGF protein in supernatant was obviously higher (P<0.01), the col agen type I, col agen type III, decorin and cartilage oligomeric matrix protein mRNA expression decreased in the ligament fibroblasts (P<0.01), but the mRNA expression of Scleraxis, col agen type I, col agen type III in bone marrow mesenchymal stem cel s increased (P<0.01). The results suggest that the co-culture of Ad-bFGF-transfected bone marrow mesenchymal stem cel s with ligament fibroblasts promotes the proliferation of ligament fibroblasts while decreases the col agen synthesis at the same time, and stimulates the proliferation and differentiation of bone marrow mesenchymal stem cel s into ligament fibrolasts.

AIM: To explore the relationship between proliferation, hypertrophy of vascular smooth muscle cells(VSMC) and platelet-derived growth factor-AA(PDGF-AA) and PDGFR-? expression in spontaneously hypertension rats(SHRs) and the role of tyrosine protein kinase (PTK) in it. METHODS: 1. The difference of PDGF-AA, PDGFR-? and PDGFR-? expressions in SHR/Wistar-kyoto rat(WKY)-VSMC was examined by Western blot. 2.The effect of PTK inhibitor (genistein) on proliferation and hypertrophy of SHR-VSMC induced by PDGF-AA was observed by Western blot and incorporation. RESULTS: 1.PDGF-AA and PDGFR-? expression markedly increased in SHR-VSMC compared with WKY-VSMC. There was no difference in PDGFR-? expression levels between SHR and WKY-VSMC. 2.Dose-dependent PDGF-AA-stimulated PCNA expression and incorporation were observed in SHR-VSMC. 3. Genistein inhibited PCNA expression and incorporation induced by PDGF-AA in a dose-dependent manner in SHR-VSMC. CONCLUSIONS: Spontaneous increasing expression of PDGF-AA and PDGFR-? in spontaneously hypertension rats(SHRs) may be one of the important factors in vascular reactivity and vascular modeling mediated through proliferation and hypertrophy in SHR-VSMC. Tyrosine protein kinase plays an important role in this process.
