Objective To detect the changes in cTnI and CK MB during extracorporeal circulation and the myocardial injury by extracorporeal circulation. Methods The value of cTnI and CK MB was determined in 30 persons during extracorporeal circulation. We divided them into 6 groups according to pre operation, 6, 12, 24, 48 and 72 hours after operation. Modified method (Bodor et al) was used to detect cTnI, and immune suppression method to detect CK MB. Results cTnI and CK MB were, cTnI ( ?s ) (5.20?2 80) ?g/L,CK MB ( ?s ) (10.75?4.70) U/L in 28 persons. They elevated 6 hours after operation. 12 24 hours after operation cTnI and CK MB increased to the maximum, cTnI 28.80 71.30 ?g/L,CK MB 55.60 71.30 U/L. During 48 72 hours, CK MB decreased to normal, 49.70 22.80 U/L. cTnI was 9.40 19.80 ?g/L 72 hours after operation. Conclusion Extracorporeal circulation may cause myocardial diseases. cTnI is a more sensitive biochemical marker for myocardial diseases.

Objective:To determine the distribution of CD4+CD25+FOXP3+ regulatory T cells (Treg) and Treg subsets in human colorectal carcinoma microenvironment and to explore their correlation with conventional clinico-pathological features.Methods:Frozen sections and Immunohistochemistry (IHC) were used to detect FOXP3+ Treg in fresh specimen collected from 42 patients with colorectal carcinoma.The number of FOXP3+ Treg was evaluated in terms of its association with clinico-pathological feature in tumor and peri-cancer tissue.Double staining was performed to determine the expression of ICOS and FOXP3.Results:The number of FOXP3+ Treg in the colorectal carcinoma (mean 24.1) was significantly higher than that in peri-cancer tissue (mean 0.7).A higher number of tumor infiltrating FOXP3+ Tregs was found in the patient groups with poor differentiation,lymphatic metastasis and non-distant metastasis as compared to the patient groups with well differentiation,non-lymphatic metastasis and distant metastasis.The percentage of FOXP3+ ICOS+ Treg was higher in colorectal carcinoma(81%) than that in peri-cancer tissue(10%).Conclusion:Increased FOXP3+ Treg may influence the occurrence and development of colorectal carcinoma.Our data support the hypothesis that tumor infiltrating FOXP3+ Tregs attenuate the immune response against cancer and suggest that strategy to overcome FOXP3+ Treg function may be beneficial in the treatment of human colorectal cancer.

BACKGROUND: Previous studies have proved that stress can affect immunity function and disturb homeostasis of bodies. Moderate exercise can alleviate the psychological stress reaction to some degree.OBJECTIVE: To observe the effects of moderate exercise on lymphocyte number in spleen and mesenteric lymph nod,interferon-y (IFN-γ) and interleukine-4(IL-4) level in serum, as well as Th1/Th2 balance in rats under chronic psychological stress.DESIGN, TIME AND SETTING: A randomized control animal experiment was carried out in the laboratory of Sports Human Science in Chengdu Sports University from May to October in 2007.MATERIALS: A total of 40 healthy male SD rats were divided by random digits table into 4 groups: control group, psychological stress group, exercise group and exercise+psychological stress group, with 10 ones in each group.METHODS: Before experiment, rats in exercise group and exercise+psychological stress group underwent 3 days of adaptive swimming training, 30 min/(t·d). During experiment, they were made swimming with no weight loading for 8 weeks, 60 min/(t·d).From day 2 post exercise on, rats in exercise+psychological stress group began to undergo the 21 days of chronic restraint stress,6 hours per day. At the same time, the chronic restraint stress models were established in the psychological stress group. Rats in the exercise group were fed for 22 days since the 8~(th) day of exercise ended. Rats in the control group were only fed without any intervention.MAIN OUTCOME MEASURES: The lymphocyte number in spleen and mesenteric lymph node was measured, and ELISA was employed to measure IFN-y and IL-4 levels as well as the ratio of IFN-y/IL-4 in serum.RESULTS: Compared with the control group, the lymphocyte number, the level of IFN-y and the ratio of IFN-y/IL-4 were significantly decreased in psychological stress group (P < 0.01 ), and the Thlf'rh2 balance was broken. Compared with the psychological group, the exercise+psychological stress group had got significantly higher lymphocyte number, IFN-γ level and ratio of IFN-γ/IL-4 (P<0.05). The lymphocyte number in spleen and mesenteric lymph node in the exercise group showed not a difference of significance compared with the control group, but a tendency towards going up. There was no difference of significance in IFN-γ level and ratio of IFN-γ/IL-4 among the exercise+psychological stress group, the exercise group and the control group.CONCLUSION: Moderate exercise can increase lymphocyte number in spleen and mesenteric lymph node significantly,up-regulate the IFN-γ level so as to regulate the disbalance of Th1/Th2, and maintain immunity homeostasis.
