ObjectiveTo investigate the effect of psychological intervention on quality of life (QOL) of patients with mammary carcinoma.Methods64 patients with mammary carcinoma were divided into intervention group (n=36) and control group (n=28), and psychological status and QOL of patients of two groups were analyzed after treatment.ResultsThe psychological status and QOL of intervention group was better than that of control group (P<0.05～0.001).ConclusionThe psychological intervention in full stage being in hospital can improve QOL of patients with mammary carcinoma, and it is clinically significant to improve cure rate and survival rate of patients.

Extranodal nasal type NK/T cell lymphoma (ENKTL) is a highly aggressive non-Hodgkin lymphoma.Due to its low occurrence even in prevalent areas,there has been no large sample randomized controlled clinical trials.Therefore,no standard therapeutic strategy is currently identified in this disease.Tumor cells are insensitive to conventional anthracyclines-containing chemotherapy because of high expression of multi-drug resistant gene 1.Regimens that incorporate the use of L-asparaginase or gemcitabine result in substantial improvements in overall response rate and are promising treatment for ENKTL.Targeted therapy,immunomodulatory therapy and hematopoietic stem cell transplantation are still under research.

Objective　To observe the effects and mechanism of TNFα and IL-1 on protein catabolism of skeletal muscles of mice in the early stage of severe burn. Methods　A BALB/c mice model was established with full thickness scalded of 18%～20% TBSA including the back and one hind limb. The catabolic rate of protein of soleus muscle was reflected with the net tyrosine releasing rate. The changes of the tyrosine releasing rates of the injured and uninjured limbs, the levels of TNFα and IL-1 of the plasma and soleus muscle, and the activities of lysosomal proteolytic enzymes were observed in 72 h after scald injury of the mice. Results　After injury, the levels of TNFα and IL-1 of plasma, injured and uninjured limbs were all increased, and reached the summit at the 48th h, but those of the injured limb were much higher than those of the uninjured one, then gradually the levels were decreased in 72 h. The protein catabolic rate of uninjured limb was higher than the normal at h 48, but it came to normal level at h 72. The rate of the injured limb was higher than that of normal and uninjured limbs significantly 72 h after the scalding. hrTNFα and hrIL-1 enhanced the protein catabolic rate and the activities of lysosomal protrolytic enzymes in the soleus muscle of normal mice in vivo and in vitro respectively. Conclusion　In the early stage of scald injury, TNFα and IL-1 could enhance the lysosomal protease activity, increase the protein catabolic rate in skeletal muscle and promote the negative nitrogen balance directly. These effects may not depend on the actions of emergent hormones.

Objective: To investigate the effects of Bcl-2 shRNA on the growth of liver carcinoma cell line BEL-7402 and colorectal carcinoma cell line Caco2. Methods: Bcl-2 shRNA was cloned into Pgenesil-1 plasmid labeled with fluorescent protein and the product was transfected into BEL-7402 and Caco2 cells with Lipofectamine 2000. The study also included shRNA as negative control, Pgenesil-1, Lipofectamine and blank control groups. Transfected cells were visualized by inverted fluorescent microscope and then assayed by flow cytometry. The expression levels of Bcl-2 protein were assayed by Western-blot and cell proliferation was measured by MTT method. Results: There was no difference in transfection rate among cells in Bcl-2 shRNA, shRNA and Pgenesil-1 vector groups. Western-blot assay showed that the expression levels of Bcl-2 protein in BEL-7402 and Caco2 cells were significantly decreased in Bcl-2 shRNA group compared with those in other 4 groups (P<0.05). Furthermore, Bcl-2 shRNA had a stronger inhibitory effect on Caco2 cells than on BEL-7402 cells (P<0.05). MTT assay showed that Bcl-2 shRNA significantly inhibited the growth of BEL-7402 and Caco2 cells (at 72 and 96 h after treatment, respectively) compared with the other 4 groups (P<0.05). Conclusion: Bcl-2 shRNA can specifically inhibit the growth of BEL-7402 and Caco2 cells.

Objective: This work studied platelet-neutrophil aggregates (PNA) expression in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: Our research included in 2 groups: STEMI group, n=40 patients admitted in our hospital and Control group, n=30 normal subjects. Blood levels of PNA, platelet-monocyte aggregates (PMA) and platelet-lymphocyte aggregates (PlyA) were measured by lfow cytometry at admission and the results were compared between 2 groups. Results: Compared with Control group, STEMI group had similar blood levels of PlyA and PMA,P=0.245 andP=0.312; while increased blood level of PNA,P<0.05. Correlation analysis showed that platelet-leukocyte aggregates (PLA) level was positively related to CK-MB (r=0.4992,P<0.01) and cTnI (r=0.4365,P<0.01). Conclusion: Blood level of PLA, especially PNA was significantly higher in STEMI patients which suggested that increased PNA might be sued as a new index for AMI diagnosis in clinical practice.
