Disdvantages of chemotherapy in treating breast cancer were insensitivity or intolerance.There were different opinions on chemotherapy in treating negative axillary lymph notes or positive hormone receptors after breast cancer surgery.The advantages of TCM in treating breast cancer were:there were many Chinese medical oncologists who had rich clinical experiences in treating breast cancer before and during surgery,before and during chemotherapy,before and during radiotherapy and during the consolidation period;treatment according to syndrome differentiation with TCM for different stages of breast cancer had been gradually standardized;a well developed network of academic information provided a good platform for establishing the unified treatment protocols with TCM for different stages of breast cancer.It was indicated that large scale prospective clinical trials with TCM in the treatment of after-surgery breast cancer patients who had negative auxillary lymph notes and positive hormone receptors should be carried out.

According to the problem existing in PBL teaching of biochemistry, we reformed teaching approach, adjusted curriculum content, reassembled teaching material system, emphasized clinical practice, strengthened the experiment technique, expanded open class, created essential condition, built independent learning atmosphere actively, which promoted teaching quality enormously and demonstrated great advantage of PBL teaching method. Meanwhile, it made the curriculum reform of biochemistry carried out deeply.

To adapt the requirements of cultivating high-quality medical talents,we implemented autonomous management model on selecting courses,research subjects,classic discussion,experiments and practice. This reformation is effective. One step further,we illustrated its significance from medical view: doctors,patients and diseases. Meanwhile,it was pointed out that the autonomous management is an inevitable trend for management development in the future.

Objective To investigate the potential role of MCP-1/CCL2 in experimental acute necrotizing pancreatitis (ANP) and complications. Methods 60 SD male rats were randomly divided into 3 groups: sham operation group ( n = 20 ), ANP group ( n = 20 ) and MCP-1 group ( n = 20 ). ANP model was induced by retrograde infusion of 3.5% sodium taurocholate, MCP-1 group received subcutaneous injection of MCP-1 antibody 0 h and 6 h after ANP induction. The serum levels of amylase, MCP-1, D-lactic acid,histological changes and the expression of MCP-1 mRNA of lung, small intestine and pancreas, the expression of MCP-1 protein in pancreas, MPO levels of small intestine MPO were determined. Results The serum levels of amylase, MCP-1, D-lactic acid in MCP-1 group at 12 h were (4666 ±412)U/L, (39.53 ±8.25)pg/ml and (6.3 ±2.2)mg/L, which were significantly lower than those in ANP group [ (9611 ±363)U/L, (63.42 ±9.32) pg/ml, (9.3 ± 2. 1 ) mg/L, P< 0.05 ) ]; the expression of MCP-1 mRNA in pancreas, small intestine and lung were 0.431 ± 0.009, 0. 211 ± 0.018 and 0.442 ± 0.017, which were significantly lower than those in ANP group [ (0.624 ±0. 010, 0. 523 ±0. 019 and 0. 569 ±0. 024, P <0.05) ]; the expression of MCP-1 protein in pancreas was 2.0 ± 0. 1, which was significantly lower than that in ANP group (4. 0 ± 0. 2, P <0.05). Lung and small intestine MPO were (11.1 ±3.0)U/g and ( 19.2 ±2.0)U/g, which were significantly lower than those in ANP group[(39.2±3.1)U/g and(13.1±2.1)U/g, P<0.05]. Conclusions Early blockade of MCP-1 not only attenuates the severity of ANP, but also decreases the degree of acute lung injury and intestine barrier dysfunction.

Aim To investigate the effects of monocrotaline pyrrole on production of nitric oxide and expression of eNOS protein of cultured pulmonary artery endothelial cells and on contractility of cultured pulmonary artery smooth muscle cells.Methods DAF-2 fluorescence technique was used to determine NO level,Western blot analysis was performed to determine the level of eNOS protein,and collagen gel contraction system was adopted to analyze muscle contractility.Results NO production induced by ACh and expression of eNOS protein were obviously inhibited by monocrotaline pyrrole compared with those of control group and gel contraction area in MCTP-treated cells induced by Thapsigargin obviously decreased.Conclusions monocrotaline pyrrole could inhibit the level of the ACh-induced production of NO and expression of eNOS protein,and enhance the contractility of pulmonary artery smooth muscle cells,which may be one of the possible mechanisms of MCTP-induced pulmonary artery hypertension.
