Objective To study the mechanism of Chinese Medicine in treating adenomyosis. Methods Thirty-seven patients in the Chinese Medicine treated group (17 cases of adenomyosis) and the control group (20 cases of adenomyosis, non-drug treated) underwent hysterectomy. Endometrium was looked as eutopic endometrium and adenomyosis as ectopic endometrium. Expression of MMP-9 and TIMP-1 in eutopic and ectopic endometrium were measured by immunohistochemical techniques. Meanwhile the levels of CA125 in serum were measured. Results The ectopic endometrium of the Chinese Medicine treated group expressed lower level of MMP-9, higher level of TIMP-1 and lower ratio of MMP-9/TIMP-1 than the ectopic endometrium of the control group (P<0.05). The levels of CA125 in serum were significantly decreased in Chinese Medicine group after treated as contrast with those in control group. Conclusion Chinese Medicine could reduce the level of CA125 and the ratio of MMP-9 and TIMP-1 to prevent the progression of adenomyosis.

ObjectiveTo explore the causes and countermeasures for extravasation of intravenous fluids in children. Methods726 cases of intravenous infusion in pediatric surgery department from May to December 2011 in our hospital were observed. ResultsThere were 30 cases with extravasation of intravenous infusion in the 726 cases,the leakage rate was 4.13％.The specific causes of fluid extravasation included:younger age of children,not cooperating with the infusion in 18 cases,accounting for 60.00％,followed by non standardized fixation methods in 5 cases,accounting for 16.67％,and accompanying family members refused to be disturbed accounted for 13.33％,Nursing visits to owe in a timely manner accounted for 6.67％.The rate of younger age of children and lack of cooperation leading to fluid extravasation were significantly higher than other causes,the difference was statistically significant. ConclusionsChildren age,fixation method,cooperation of family members,inspections and other factors can be controlled.Along with the continuous improvement of medical standards and a variety of active and effective implementation of the measures,these factors can be controlled effectively.Strengthening the training of nurses and vocational skills to enhance their own sense of responsibility,to give standardized infusion operation and fixation,and give predictable observation and treatment,can effectively prevent the occurrence of extravasation of intravenous fluids.

To explore a method of identifying myocardial capillaries and to use it to observe the effects of ischemic preconditioning on the myocardial capillaries. Anesthetized open chest dogs in ischemic preconditioning (IP) group ( n =6) were subjected to 5min ischemia and 5min reperfusion for 4 cycles before 1 hour of left descending coronary artery (LDA) occlusion followed by 2 hours of reperfusion, while in the ischemia reperfusion (IR) group ( n =6) they were only subjected to 1 hour occlusion followed by 2 hour reperfusion. Myocardial samples in ischemic area were obtained to display capillaries by silver hexamethylenetetramine staining, and their quantitative analysis was conducted by imaging analyzing system. Two growps were then compared. The results showed that myocardial capillaries were clearly shown by silver hexamethylenetetramine, and it revealed that the numerical points density, numerical perimeter density and numerical profile density of myocardial capillaries in ischemic region were obviously increased in IP group compared with IR group. The results suggested the method to identify myocardial capillaries by silver hexamethylenetetramine was reliable and practical, and IP could protect the myocardial capillaries from the damage of ischemia reperfusion.
