The CO I gene sequences of Qianghuoyu, Pachytriton labiatus and Gehyra mutilata were achieved by PCR amplification and bi-directional sequencing. Furthermore, a pair of specific primers SJYW1 and SJYW2 in the non-conservative district were designed through sequence alignment. The PCR reaction condition was established by changing the annealing temperature and cycle numbers. The results showed that 350 bp DNA fragment was amplified from Qianghuoyu in PCR with annealed temperature at 54 °C and the cycle number was 25 cycles, whereas not any DNA fragment was amplified from P. labiatus and G. mutilata under the same reaction condition. This method is well-performed in the identification of Qianghuoyu for its excellent specificity and repeatability.

In this study,nearly 200 endophytic bacteria were isolated from different part of Huperzia serrata, over 60 bacterium with clear antifungal activity were selected from those cultures.Among them,strain H-6 exhibited the highest antifungal activity which was strongly inhibits the growth of many plant pathogenic fungi such as Sclerotinia scleroliorum,Fusarium graminearumt,Sclerotinia libertiana,Phytophthora capsici Leonia and Sesame fusarium wilt.According to the characteristics of morphology,physiology and biochem- istry tests and the comparison of 16S rDNA sequence,the strain H-6 was similar to the Burkholderia.So strain H-6 was identified as Burkholderia sp.H-6.The results also showed that Burkholderia sp.H-6 was markedly different from Burkholderia cepacia that was applied widely in agriculture as antagonistic bacteria. The medium and culture conditions of the strain all were optimized by single factor and orthogonal experiments.In the investigation of the culture condition,growth was carried out in a basal medium(potato juice)and gradually supplemented with the various ingredients to be investigated.The major ingredients be- ing investigated included carbon sources and nitrogen sources.The optimal antifungal activity production condition is growth in a medium(potato juice with 2.5%mannitol and 0.1%NaNO3),initial pH 4.0 at 28℃.

The type of basic media and the contents of plant growth substances were investigated by orthogonal design experiment,and also the effects of different culture conditions on the growth of suspension cells and the accumulation of total flavonoids in Eucommia ulmoides were studied.The results showed that B5 medium supplemented with 0.5mg/L NAA,0.6mg/L 6-BA and 30g/L sucrose,at initial pH 5.0～5.5,20g(FW)/L inoculation quantity and 110 r/min of rotation speed was a preferable culture conditions for E.ulmoides suspension cells growth and flavonoids synthesis.The results of metabolic kinetics analysis for E.ulmoides cell suspension culture showed that the logistic and Luedeking-Piret equations can be used for describing the kinetics of cell growth,sucrose consumption and flavonoids production during the process.The maximum specific growth rate(?m),the actual growth yield based on sucrose(YG) and maintenance coefficient(m) were 0.417/d,0.619g/g and 0.0206g/(g?d-1) respectively.All these outcomes could give a basis for establishing the suspension cell culture of E.ulmoides and production of the natural active components in large-scale.

Objective To investigate the efficacy and security of cypher stent(sirolimus-eluting stent)in the treatment of old patients with coronary heart disease(CHD).Methods From November 2002 to May 2005,328 elderly CHD cases(age:60-86 years)were treated with 415 Cypher stents.Among the 328 patients,66 had ST-segment elevation of myocardial infarction,21 had non ST-segment elevation of myocardial infarction,149 had unstable angina and 92 had stable angina.As for lesion characteristics,diffuse disease was found in 91 case(26.1%),bifurcation lesions in 68 cases(19.6%),chronic total occlusion lesions in 56 cases(16.0%),in-stent restenosis in 14 cases and ostial lesions in 15 case.The immediate angiographic outcome,major cardiac event(MACE) and angiographic follow-up at 6 months were assessed.Results Stent implantation was successfully achieved in 99% patients with CHD.Acute and sub-acute stent thrombosis occurred in 2 patients,late stent thrombosis with AMI occurred in 2 patients,1 died during the 6 months follow-up.The MACE rate during hospitalization was 0.6% and 3.6% during 6 months follow-up.Angiographic follow-up in 84 patients at 6 months showed that in-stent restenosis rate(ISR)was 8.3%(restenosis within the stents was 2.4%).The target vessel revascularization(TLR)rate was 5.9%.Conclusions Cypher stent implantation in CHD is safe and effective,the ISR rate and TLR rate are significantly lower than those of bare metal stents.

BACKGROUNDCell-based vascular therapies of endothelial progenitor cells (EPCs) mediated neovascularization is still a novel but promising approach for the treatment of ischemic disease. The present study was designed to investigate the therapeutic potentials of human umbilical cord blood-derived EPCs (hUCB-EPCs) in rat with acute myocardial infarction.

METHODSHuman umbilical cord blood (hUCB) mononuclear cells were isolated using density gradient centrifugation from the fresh human umbilical cord in healthy delivery woman, and cultured in M199 medium for 7 days. The EPCs were identified by double-positive staining with 1, 1'-dioctadecyl-3, 3, 3', 3'-tetramethylindocarbocyanine percholorate-labeled acetylated low-density lipoprotein (Dil-Ac-LDL) and fluorescein isothiocyanate-conjugated Ulex europaeus lectin (FITC-UEA-l). The rat acute myocardial infarction model was established by the ligation of the left anterior descending artery. The hUCB-EPCs were intramyocardially injected into the peri-infarct area. Four weeks later, left ventricular function was assessed by a pressure-volume catheter. The average capillary density (CAD) was evaluated by anti-VIII immunohistochemistry staining to reflect the development of neovascularization at the peri-infarct area. The graft cells were identified by double immunofluorescence staining with human nuclear antigen (HNA) and CD31 antibody, representing human origin of EPCs and vascular endothelium, respectively. Expressions of cytokines, proliferating cell nuclear angigen (PCNA), platelet endothelial cell adhesion molecule (PECAM) and vascular endothelial growth factor (VEGF) were detected to investigate the underlying mechanisms of cell differentiation and revascularization.

RESULTSThe donor EPCs were detectable and integrated into the host myocardium as confirmed by double-positive immunofluorescence staining with HNA and CD31. And the anti-VIII staining demonstrated a higher degree of microvessel formation in EPCs transplanted rats, associated with a significant improvement of global heart function in terms of the increase of left ventricular end-systolic pressure (LVESP), +dp/dtmax and -dp/dtmax as well as the decrease of LVEDP in rats with EPCs therapy comparing to the control rats (P < 0.05). Moreover, the expression of the rat PCNA mRNA and PECAM were both enhanced in the EPCs group compared with that of the control group.

CONCLUSIONSThe human umbilical cord blood-derived EPCs could incorporate into new-born capillaries in rat myocardium, induce revascularization and improve the proliferation activity in the peri-infarct area, resulting in the improvement of global heart function. This may indicate a promising stem cell resource in cell-based therapy for ischaemic diseases.

Objective: To investigate whether fusion protein SD-HA could regulate its downstream signaling molecule activity by competing with the phospho-BCR-ABL Y177 site, and its mechanisms to inhibit proliferation and induce apoptosis of K562 cells. Methods: Co-immunoprecipitation interaction technology analysis of fusion protein SD-HA functioned by potently binding to the phospho-BCR-ABL Y177 site, Ras, MAPK and Akt activities were observed in the Ad5F35-SD-HA-treated cells. Western blot analyses of SD-HA fusion protein on cell membrane receptor pathway to death cascade caspase-8, caspase-3 and PRAP were performed. Results: Exploration into the underlying mechanisms revealed that Ad5F35-SD-HA infection functioned by binding to the phospho-BCR-ABL Y177 site, which lead to a complex with Grb2. competitively disrupted the Grb2 SH2-phospho-BCR-ABL Y177 formation. The fusion protein SD-HA could reduce the activation of Ras and phosphorylation of MAPK (p-MAPK) and the expression level of p-ELK, inhibition of Ras-MAPK signaling pathway; SD-HA fusion protein could reduce p-Akt and Akt substrate p-GSK with inhibition of PI3K-Akt signaling pathway, thereby inhibiting the proliferation of K562 cells. Caspases-8-induced apoptosis signal could be activated by DED protein binding to DED domain of precursor caspases-8. Conclusions The strategy of fusion protein SD-HA inhibiting-Y177 BCR-ABL and Grb2 binding could be used as a novel entry point for the treatment of chronic myeloid leukemia.

OBJECTIVENumber and function of endothelial progenitor cell (EPC) and coronary artery lesion in Kawasaki disease (KD) model were evaluated to investigate therapeutic efficacy of granulocyte colony-stimulating factor (G-CSF).

METHODC57BL/6 mice were injected with L. casei cell wall extract (LCWE); 48 mice were divided into 3 groups randomly: KD model group; G-CSF treated model group and control group, 16 in each. G-CSF was subcutaneously injected from day 5 to day 9 after injection of LCWE. Coronary artery lesion, number of circulating EPC and the function of bone marrow EPC were evaluated.

RESULTIn model group, inflammatory infiltration was found around coronary artery at 14 days. The number of circulating EPC was significantly decreased in model group (0.017% ± 0.008%) compared to control (0.028% ± 0.007%) (t = 2.037, P < 0.05). Disruption of elastin was consistently observed at 56 days. Stimulated by G-CSF, inflammatory infiltration was found around the coronary artery at day 14, while the number of circulating EPC (0.042% ± 0.015%) was increased significantly compared to models (t = 4.629, P < 0.05). At the day 56, the number of circulating EPC was decreased slightly (0.029% ± 0.012%), but still higher than the model group (t = 2.789, P < 0.05), and have no significant difference compared to controls (P > 0.05). Furthermore, there was no elastin disruption in the G-CSF group. In model group, bone marrow EPC's proliferation ability of absorbance (A value) was 0.38 ± 0.09 in thiazolyl blue assay, less than controls (0.61 ± 0.14, P < 0.01). Adhesion and migration function were down-regulated compared to controls [(3.1 ± 0.6) cells/HPF and (3.3 ± 0.6) cells/HPF vs. (6.4 ± 1.2) cells/HPF and (6.2 ± 0.5) cells/HPF, both P < 0.01]. In the G-CSF treated group, proliferation ability (A 0.58 ± 0.10), adhesion [(6.17 ± 1.13) cells/HPF], migration [(6.29 ± 0.42) cells/HPF] function were increased significantly compared to the model group (P < 0.01).

CONCLUSIONG-CSF can up-regulate EPC number and function to prevent coronary artery lesion in mice model of KD.

OBJECTIVETo investigate the clinical efficacy of rectocele repair with longitudinal incision and transverse suture on the vaginal posterior wall.

METHODSOne hundred and forty-six patients with rectocele were enrolled in our study from August 1999 to August 2003. The patients were randomly divided into two groups, and received traditional repair with longitudinal incision and longitudinal suture (control group, n=74) or repair with longitudinal incision and transverse suture on the vaginal posterior wall (study group, n=72). The efficacy and complications were compared between the two groups.

RESULTSIn the study group,only one case (1.4%) had no effect, and the total effective rate was 98.7%. The mean course of treatment was (11.0+/- 1.9) days. Only two cases (2.7%) had postoperative complication. In the control group, 8 cases (11.1%) had no effect, and the total effective rate was 88.9%. The mean course of treatment was (17.4+/- 1.6) days. Twenty-nine cases (40.3%) had postoperative complications. There were significant differences in the efficacy and complications between the two groups (both P< 0.01).

CONCLUSIONThe refined rectocele repair with longitudinal incision and transverse suture on the vaginal posterior wall has good efficacy with shorter curative period and less complications.
