Objective:To observe the expressions of MTA1 mRNA and ki67 in breast cancer tissue and to investigate the relation between the two indexs and their correlation with the invasion ability of breast cancer.Methods:The expressions of MTA1 mRNA and ki67 were detected by ISH and IHC,respectively.And their correlation was analysed.Results:The expressions of MTA1 mRNA and ki67 in the poorly differentiated group of breast cancer were significantly higher than that in the moderately and well differentiated groups (P

OBJECTIVE To monitor the hand contamination after dressing change for the infected wound and to explore an effective way for hand hygiene. METHODS Caregivers were divided into three groups after applying dressing on infected wound:group 1(no hand-washing),group 2(regular hand-washing),and group 3(standard hand-washing),the pathogens in hands were monitored and the effects of two ways of hand-washing were compared. RESULTS The rate of hand-carrying pathogens after dressing change for the infected wound was 100.0%,the qualified rate of regular hand-washing was only 47.9% and that of standard hand-washing (six-steps method)was 97.9%. CONCLUSIONS The standard hand-washing is more effective than regular hand-washing. Correct hand hygiene should be emphasized to prevent and control nosocomial infection.

BACKGROUND: The glycoprotein which ends of a-galactosyi residues (a-Gal) is the major heterogenic antigen for hyperacute rejection. OBJECTIVE: To observe the distribution characteristic of the small tissue engineered vessel scaffold, and a-Gal in endothelial cells and smooth muscle cells of Wistar rats and Japanese white rabbits, in addition, to discuss the feasibility of applying acellular tissue vessel scaffold to heterogeneous blood vessel transplantation. DESIGN, TIME AND SETTING: The contrast observation was conducted at the Department of Human Anatomy of China Medical University between March 2003 and December 2004. MATERIALS: Totally 30 caudal arteries of Wistar rats were collected. Fifteen of which were prepared for small vessel scaffold (small vessel scaffold group), the remained 15 served as caudal artery group. Additionally, 15 central arteries were obtained from each ear of Japanese white rabbits (central artery group). METHODS: Totally 16 mg/L Bandeiraea Simplicifolia I Isolectin B4 (BSI-B4) was added for DAB staining with Affinity histochemistry method. Then MetaMorth/C5050/BX41 microscopic image analysis system was used to detect the positive reaction product of a-Gal. MAIN OUTCOME MEASURES: Color changes of vascular wall were observed under light microscope; the optical density of the positive reaction product of a-Gal was measured. RESULTS: The expression of a-Gal was mainly located in the cell membrane, as well as cell nucleus of endothelial cells in the central artery group. The expression of a-Gal of endothelial cell was strong positive in the caudal artery group, which was weak or negative expressed in the small vessel scaffold group. The optical density of a-Gal expression was lowest in the tunica intima of small vessel scaffold group, which was less in the central artery group than the caudal artery group (P < 0.001). The a-Gal expression in the tunica media of small vessel scaffold group was less than the central artery and the caudal artery groups (P < 0.001). CONCLUSION: In the caudal artery of Wistar rat, the expression of a-Gal is higher than that in the central artery of Japanese white rabbit. Therefore, the heterogeneous tissue engineered vessel material from acellular caudal artery of Wistar rats can be used in blood vessel transplantation.

Objective:To discuss the method of surgery treatment for nodular goiter,Graves disease,Hashimoto thyroiditis and differentiated thyroid carcinoma. Methods:A retrospective analysis of the clinical records of 76 patients undergoing total thyroidectomy was analyzed for the method of surgery treatment for thyroid diseases from resection extent,operative techniques,intraoperative and postoperative complications. Results:Five patients(78.4%)of all the patients accepted total thyroidectomy in first operation had transient or short-term completely recovered hypocalcemia postoperatively,and there were no cases with injury of recurrent laryngeal nerve. 4 patients(33.3%) had one-sided recurrent laryngeal nerve injury and temporary hypoparathyroidism in recurrent patient,and one of the cases had permanent hypoparathyroidism. Conclusion:Total thyroidectomy could be served as the routine operative method for multinodular goiter,Graves disease,Hashimoto thyroiditis and differentiated thyroid carcinoma.

OBJECTIVE To investigate the impact of disinfection quality in surgical dressing room on the healing of wound with dressing exchanges in order to implement procedures to prevent nosocomial infection. METHODS A retrospective investigation was performed and cases of poor surgical wound healing from Jan 2006 to Dec 2007 were collected and analised. Effective measures were taken to enhance the management and surveillance in the dressing room. RESULTS After taking the prevention procedure,the passing rate of disinfection was increased. Before implementing the prevention procedure the passing rates of air,surface and finger cultured were 83.3%,83.3% and 75.0%,respectively,After taking the prevention procedure the passing rates of above were all 100.0%.The rate of poor wound healing decreased from 4.16% to 1.59%. CONCLUSIONS The disinfection quality of dressing room has direct effects on the wound healing. The management of dressing room disinfection should be emphasized to cut down the nosocomial infections of wound.
