Objective To investigate the effects of blood transfusion on postoperative infection in patients with breast cancer.Methods 311 patients who underwent breast cancer operations in our hospital were observed.Among them,109 patients were transfused with red blood cell (RBC) concentrates,112 with white blood cell(WBC)-depleted RBC concentrates,90 were not transfused.The rates of postoperative infection of three groups were compared.Results The rate of postoperative infection of the group transfused with RBC concentrates was 5.50%.The rate of postoperative infection of the group transfused with WBC-depleted RBC concentrates was 0.89%,which was significantly different from that of the group transfused with RBC concentrates(P0.05).Conclusions In patients with breast cancer,the rate of postoperative infection of the group transfused with RBC concentrates was higher than that of group transfused with WBC-depleted RBC concentrates and of the group without transfusion. The rate of postoperative infection was closely correlated to the amount of RBC concentrates.

A medical studies have indicated that there would be a defense response from human body after TBI,which mainly comes with inflammatory reaction. Human body's resistance seems likely to be enhanced,during this process, by inflammatory cytokines leading to rehabilitation of the cellular organization.However,a strong Inflammation from the whole human body may be caused due to the excessive activation,which, instead, worsens secondary brain injury. This article discusses the relationship between cytokines and traumatic brain injury.

AIM: To know the variations of the cytochrome b gene in cancer tissue, paracarinoma tissue and normal tissue and to inquire into the relationship between mutations of mitochondrial genome and carcinogenesis. METHODS: Cellular total DNA was extracted.The cytochrome b genes of three tissues were amplifyed with polymerase chain reaction(PCR). PCR products were analysed by DNA auto-sequencing method. RESULTS: The cytochrome b gene of cancer tissue had the C to G mutation at nt 14931, the C to G mutation at nt 15004 and the T to C mutation at nt15435,respectively. The cytochrome b gene of paracarinoma tissue had the A to C mutation at nt 15436. The cytochrome b gene of normal tissue had not mutation. CONCLUSION: Mitochondrial DNA mutations could be the endogenous factors that induce nuclear genome mutation. It could promoto carcinogenesis. The paracarinoma tissue was abnormal in DNA molecular level.

Objective To investigate the expression of Notch4 protein and to analyze its correlation with the clinical parameters and the microvessel dentisty in renal cell carcinoma. Methods The expression of Notch4 was examined in 60 cases of renal cell carcinoma and the para-carcinoma tissue by SP immunohistochemical stain-ing ,and CD34 detection was used for counting microvessel density. Statistical analysis was performed to reveal the correlation with clinicopathological parameters ,microvessel density and prognosis. Results The positive rate of Notch4 protein expression was 75%(45/60)in para-carcinoma tissue,and was 43.3%(26/60)in renal cell car-cinoma,with significant difference on tumor grade and Lymph node metastasis(P<0.05). The microvessel densi-ty in Notch4 positive tissues was significant lower than that in the negative samples(P<0.05). The survival time of patients with Notch4 positive expression was significantly longer than that of patients with Notch4 negative expres-sion(P<0.05). Conclusion Notch4 protein plays an important role in the development of renal cell carcinoma. Notch4 expression might both attenuate the malignant biological characteristics and suppress the angiogenesis dur-ing tumor development.
