Objective To detect the expression of COX-2 and p53 in breast carcinoma tissue and investigate their associations with clinical prognosis.Methods The expression of COX-2 and p53 was carried out in 16 cases of normal epithelial tissue and 152 cases of breast carcinoma tissue using immunohistochemistry SP method.The correlation of their expression with clinical characteristics was analyzed using SPSS software 16.0.Survival analysis was used to investigate their effects on tumor prognosis.Results No positive COX-2and p53 expressions were observed in normal epithelial tissue.Among 152 patients,89 (58.6 ％) were positive staining rete for COX-2 and 93 (61.18 ％)were shown p53 expression, with a statistically significant associations between expressions of COX-2 and p53 and breast cancer (r =0.426,P ＜ 0.01).The COX-2 and p53 expressions were significantly correlated with pathological grade, clinical stage, lymph node or distant organ metastasis.There was a statistically significant correlation between COX-2 and p53 expression and pathological grade Ⅰ / Ⅱ.The 5-year progress-free survival (PFS) rate in patients with COX-2 over-expression was 61.3 ％, which was remarkably lower than that in those with low COX-2 expression.There was no statistically significant difference of 5-year PFS between positive and negative p53 expression.A shorter 5-year PFS was seen in patients with co-expression of COX-2 and p53 than in those with either COX-2 or p53positive expression alone and also than in those with both COX-2 and p53 negative expression.Conclusion Detection of the expressions of COX-2 and p53 can be used to predict the prognosis of breast cancer.

Objective Objective In order to better keep up with the development of transplantation immunobiology.we established and compared two types of mouse heterotopic heart transplantation,and hope to help further organ transplantation studies.Methods According to the surgical procedures of Ono's type and Chen's type of mouse model of heterotopic heart transplantation with some modification,we performed celiac and cervical heteropotic heart transplantation between iso-strains and hetero-strains,and compared the operation suecess rate,operation time,allografi survival time,and histopathology of those establishment methods.Results The success rates of mouse celiac and cervical heterotopic heart transplantation were 86.7% and 83.3%,respectively,with a non-significant difference(P>0.05) between the two methods of operation regarding the total operation time,survival time of the allografts,and histopathological findings.Conclusions Based on the mastery of microsurgical techniques,the two models of heterotopic mouse heart transplantation can be established equally,and either of them can be considered depending on the particular requirements of studies.

OBJECTIVE:To investigate the effect of shen-fu injection on toxic reaction relief in the chemotherapy for moderate to advanced non-small cell lung cancer(NSCLC).METHODS:130 patients of NSCLC were randomly divided into treatment group and control group,2 groups both received the second-generation regimen for chemotherapy,the major chemotherapeutic agents included vinorelbine,gemcitabine and paclitaxel,the treatment group was given intravenous shen-fu injection 60ml/d for continuous2weeks plus chemotherapy.RESULTS:The toxic reactions in treatment group significantly decreased compared to that in the control group(P

Objective To investigate the clinical effect of cisplatin and nedaplatin through comparing the effects of synchronous radiotherapy and chemotherapy of cisplatin and nedaplatin on patients with locally advanced cervical cancers.Methods Clinical data of 54 cases of patients with locally advanced cervical cancers received treatment at our hospital from 2009 to 2011 were analyzed retrospectively.Patients were divided into two groups according to the treatment:group DDP (cisplatin) and group NDP (nedaplatin).The general information,short-term effect,long-term curative effect,and adverse reactions were compared between two groups.Results The general information including gender,age,body mass index (BMI),stages,and pathology had no statistically significant difference between two groups.The response rate (RR)of patients in each group was 100％.The complete remission (CR) rate between groups NDP and DDP had no statistically significant difference.Among the patients ≤60 years old,the CR rate,the survival rate of 1,2,and 3 years,and the median progression-free survival (PFS) had no statistically significant difference.Among the patients ＞ 60 years old,the survival rate of 1,2,and 3 years,and the median PFS had no statistically significant difference,but the CR rate had statistically significant difference.In the non-hematological toxicity,the incidence rate of nausea and vomiting,the effect on renal function in group NDP were obviously lower than those in group DDP.There was no significant difference in liver function damage.In the hematological toxicity,there was no statistically significant difference in the incidence rate of anemia and leukopenia.The incidence rate of decrease of platelet in group NDP was higher than that in group DDP,but it was mainly reflected in the Ⅰ and the Ⅱ level.Conclusions Cisplatin had the same efficacy of concurrent chemoradiotherapy with nedaplatin for the treatment of locally advanced cervical carcinoma with a worse tolerance.
