AIM: To investigate the protective effect of calcium antagonists on anoxia/reoxygenation (A/R) injury of cardiomyocytes. METHODS: Primary-cultured cardiomyocytes were divided into four groups, namely A/R, A/R+nifedipine(Nif), A/R+ruthenium red(Ru)+heparin (Hep) and control groups. The following parameters were measured in all groups: intracellular calcium concentration ([Ca 2+ ]i), cardiac cell viability, ATP content, lactate dehydrogenase (LDH) activity in the medium, PKC and MAPK activity and -Leucine(-Leu) incorporation. RESULTS: In comparison with A/R group, A/R+nifedipine(Nif) and A/R+ruthenium red(Ru)+heparin (Hep) groups showed a marked decrease in [Ca 2+ ]i and LDH content, and a significant increase in cell viability ,ATP content, activity of PKC and MAPK and -Leu incorporation(P

ObjectiveTo retrospectively analyze the relationship between clinicopathological,biological characteristics and the outcome of renal cell carcinoma(RCC) and evaluate the risk factors related to metastasis in young patients.MethodsThe data of 83 RCC patients younger than 40-year-old, treated from January 1986 to December 2007 in Tianjin Cancer Hospital,were analyzed retrospectively.The complete follow-up data of the 83 cases were collected.The operative methods included partial and radical surgery.Clinical staging were consistent with the 2004 UICC TNM classification criterion.The histological sections were reviewed.Various biological factors including VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-α, PDGFR-β, c-kit and PCNA were tested by immunohistochemistry staining.The adjuvant radiation therapy, chemotherapy and immunotherapy after operation were carried out on the basis of pathological and biological features.The 83 cases were divided into two groups according to metastasis and non-metastasis status within 5 years.The prognosis related factors including clinical factors, pathological and biological factors were evaluated.Chi-square test was used for the analysis of 5-years metastasis status; and multivariate analysis was carried out using Cox proportional hazards models to assess the independent effect of the metastasis factors (the test standard α = 0.05).ResultsThe 5-year follow-up data showed that the metastasis rate in the 83 cases was 16.87％ (14/83).The Chi-square test results indicated that the patients with clinical stage Ⅲ and grade 3 had the highest metastasis rate (57.14％ and 78.57％respectively,x2 =38.042, x2 = 9.820; Ps ＜ 0.01) .The VEGFR-3 and PCNA positive expression rates were 92.86％ and 85.71％ respectively in metastasis group.The metastatic risk of early stage patients was 3.444 times as much as the advanced stage patients.ConclusionThe young patients with clinical advanced renal cell carcinoma had worse outcome.The stage,grade, VEGFR-3 and PCNA expression were the risk factors correlated with the metastasis risk for young RCC patients.TNM stage was an independent predictive risk factor of metastasis in young patients.

purpose To investigate the protective effect and character of dl-praeruptorin A(Pd-Ia)on focal cerebral ischemia in mice.Methods Transient focal cerebral ischemia in mice WaS induced by middle cerebral artery occlusion for 1.5 h.Pd-Ia was administered intraperitoneally either with multiple doses(1,5 and 10ms/ks)at 0.5 h before ischemia or single dose(5 ms/kg)at 0.5 h and 1 h before ischemic,the same time of ischemia,the same time of reperfusion,or 0.5 h and 1 h after reperfusion respectively.Neurological deficit score,infarct volume,brain edema,the activities of SOD and the contents of MDA were determined.Results Pretreatment with multiple doses(5 and 10 ms/ks)of Pd-Ia at 0.5 h before ischemia or single dose(5 mg/kg)of Pd-Ia at 0.5 h before ischemia,at the same time of ischemic,at the same time of reperfusion and 0.5 h after reperfusion significantly attenuated neurological deficit score,decreased infarct volume and alleviated brain edema,and the treatment at the time of reperfusion had the most marked effect.Pd-Ia(5 or 10 ms/ks)can significantly enhance the activities of SOD and lower the contents MDA.Conclusion dl-praeruptorin A has a neuroprotective effect on the injury in the acute phase of transient focal cerebral ischemia in mice,with optimal doses of 5 ms/ks and the optimal therapeutic time point of the same time of reperfusion.

Objective To evaluate the clinical effectiveness of a new and easy-to-use thrombus-aspirating device for primary percutaneous trans-radial coronary intervention (PCI). Method From March 2006 to June 2008, fifty acute myocardial infarction (AMI) patients with angiographic evidence of high-burden coronary throm-bus treated with thrombus aspiration were enrolled in a single center retrospective study. Thrombotic clot was aspi-rated before stent was implanted in the infarct-related coronary artery. Thrombolysis in myocardial infarction(TIMI) flow, corrected TIMI frame count (cTFC), TIMI myocardial perfusion grade(TMPG), and rate of no-reflow were observed with coronary augiography. Acute thrombosis and subacute thrombosis in stent during hospital stay were investigated. Myocardial ischemic events, revascularization and mortality during the following period were also in-vestigated. Paired t -test was used for statistical analysis. Results Thrombus was completely removed in 35 pa-tients (70%) and partially removed in 15 patients (30%) seen immediately after thrombus aspiration. There were significant improvements both in postoperative TIMI flow (0 vs. 2.7±0.5, P <0.01) and TMPG (0 vs. 2.6±0.8, P <0.01), while cTFC was 20.2±16.8 after the thrombus aspiration. No severe complication occurred during and after operation. Conclusions Trans-radial thrombas-aspiration in primary PCI is clinically safe and feasible. The use of aspiration catheter (ZEEK) is a simple and effective approach to the treatment of coronary artery stenosis associated with thrombus because it elevates the successful rate of treatment,reduces the incidence of no-reflow,and results in better prolonged-term outcome.

Objective To investigate the risk factors,clinical and coronary angiographic characteristics in women less than 50 years with coronary heart disease(CHD).Methods One hundred and twenty-six women less than 50 years were divided into CHD group and non-CHD group according to the result of coronary angiography(CAG).Risk factors,clinical and coronary angiographic characteristics were investigated retrospectively.Results In 6395 cases who were given CAG in the corresponding time period,126(1197%)women were less than 50 years,and 44 cases were confirmed as having CHD by CAG[CHD group,mean age(46.8±3.6)years)].Meanwhile 82 cases were in non-CHD group[mean age(45.4±4.3)years)].The incidence rate of hypertension[77.3%(34/44)vs 26.8%(22/82)],diabetes mellitus[34.1%(15/44)vs 4.9%(4/82)],hyperlipidemia[43.2%(19/44)vs 7.3%(6/82)],family history of CHD[43.2%(19/44)vs 7.3%(6/82)],and risk factors of family history of CHD[52.3%(23/44)vs 12.2%(10/82)]had significant difference between CHD group and non-CHD group(P<0.01).88.6%(39/44)CHD palients were acute coronary syndrome,50.0%(20/44)lesion was one-vessel lesion.Left anterior descending coronary was involved most easily.The degree of calcification was lighter.The type.of lesion was mostly localized and segmented.Conclusions Hypertension,hypedipidemia,diabetes mellitus,family history of CHD,and risk factors of family history of CHD are the major risk faetom in women less than 50 years with CHD. The possibility of CHD is higher when having classical angina and multiple risk faetom.

Salmonella enterica serovar Cerro 87, which was isolated from a commercial egg-producing farm, has a phosphorothioated DNA backbone resulting DNA degradation(Dnd) during the pulsed field gel electrophoresis (PFGE) process. In this research, a gene deletion mutant XTG103 was engineered with the entire dnd gene cluster knocked out by double crossover using vector pKOV-kan, and lost Dnd phenotype corre- spondingly. We regulated the DNA phosphorothioation by heterogenous expression of dnd gene cluster with an isopropyl ?-D-1-thiogalactopyranoside (IPTG) inducible promoter PlacZ.
