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.

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

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.

Objective To investigate the rationality of antibiotic use in Chongqing before and after intervention and its inter vention effect.Methods 16 200 cases,54 000 outpatient prescriptions and annual average antimicrobial consumption in 2011 from Chongqing sub network of Health and Family Planning Commission antibacterial drug monitoring network were selected as control group;48 600 cases,162 000 outpatient prescriptions and annual average antimicrobial consumption from 2012 to 2014 were selected as intervention group.The use rate of antimicrobial agents in outpatients,the intensity of antimicrobial use in hospitalized patients,the percentage of antimicrobial use in hospitalized patients,the average number of antimicrobial use in hospitalized patients,the combined use of antibiotics and other antimicrobial agents in hospitalized patients were retrospectively studies.Results Except for the utilization rate of antibiotics in the outpatients and the density of antimicrobial agents in hospitalized patients,the utilization rate of antibiotics in the hospitalized patients,the microbiology inspection rate of application of antibiotics in non surgical treatment (％),the average use days of antibiotics in the hospitalized patients(days) and the combination rate of antibiotics in the hospitalized patients from 2012 to 2014 (after intervention) had significant impact in comparison with 2011 (before intervention).Conclusion Through the clinical pharmacistes' participating in the intervention in reasonable use of antibiotics and a variety of powerful intervention measures,the rationality of antibiotic use is feasible.

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 evaluate anti-HEV IgG and IgM diagnostic kits with sera from convalescent hepatitis E patients and to establish the quantification method of detecting anti-HEV lgG.Methods Detect 42 convalescent serum samples of over 6 months after onset of hepatitis E patients from Jiangsu province with anti-HEV IgM and IgG diagnostic kits. Select and mix the anti-HEV IgG positive sera which were confirmed by Western blot with ORF2 and ORF3 antigen. The mixed serum was calibrated with a WHO anti-HEV Ig standard. A series quantitative linear standard was made for quantitative detection of anti-HEV IgG in hepatitis E vaccine clinical trials phase Ⅲ. Results The positive rates of the anti-HEV IgG di-agnose kits of G, K, MP, Wantai were 71.4%, 78.6%, 92.9% and 100% respectively. The positive rates of G was lower than that of MP (χ~2 = 5.19, P<0.05) and obviously lower than Wantai (χ~2 = 11.76,P<0.01). The positive rates of K was also obviously lower than that of Wantai (χ~2 =7.96, P <0.01).The positive rates of the anti-HEV IgM diagnose kits of MP, G, X, Wantai, K were 21.4%, 7.1%,21.4%, 64.3%, 78.6% respectively. The positive rate of both K and Wantai were obviously higher than that of MP(χ~2 = 15.75 ,P<0.01 ; X2 = 27.43 ,P< 0.01). With the Western blot confirmation test, 30 and 18 sera were reactive to ORF2 and ORF3 antigen separately. The anti-HEV IgG concentration of HEV-D01 mixed by 13 samples was 57.94 U/ml by the calibration. Prepare seven 1.5-fold dilution series of quantita-tive linear standard for HEV vaccine clinical trials phase Ⅲ, concentration range from 0.077 to 0.877 U/ml. The quantitive values of high, medium and low concentrations quality control samples lay in the range of average ± 2s, and the CV of quantitative values were 16%, 16%, 12% respectively. Conclusion The quality of different anti-HEY IgM and IgG diagnose kits were different. This study had set up a set of anti-HEV IgG linear quantitative standard, which fit for detecting anti-HEV IgG antibodies quantitatively in HEVvaccine clinical trial phase Ⅲ.
