Objective To evaluate the effect of ischemic postconditioning on myocardial injury in the patients undergoing cardiac valve replacement under cardiopulmonary bypass (CPB).Methods Thirty patients of both sexes,aged 21-59 yr,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ (New York Heart Association Ⅱ or Ⅲ),with left ventricular ejection fraction ≥ 40％,scheduled for elective cardiac valve replacement under CPB,were divided into 2 groups (n=15 each) using a random number table:control group (C group) and ischemic postconditioning group (P group).In group P,ischemic postconditioning was induced by 3 cycles of 30 s aortic unclamping followed by 30 s cross-clamping starting from 5 min before complete opening of the ascending aorta.After induction of anesthesia and before operation (T1),at 1 h after opening of the ascending aorta (T2),at the end of operation (T3),and at 12,24 and 48 h after opening of the ascending aorta (T4-6),blood samples were taken from the radial artery for determination of plasma concentrations of heart-type fatty acid-binding protein (H-FABP),ischemia-modified albumin (IMA),and cardiac troponin Ⅰ (cTnI).Myocardial specimens in the right auricle were obtained at T2,and the pathological changes were examined using an optical microscope.Results The concentrations of plasma cTnI at T2-6 and H-FABP and IMA at T2-5 were significantly higher than those at T1 in the two groups (P＜0.05).Compared with group C,the concentrations of plasma cTnI at T2-6,H-FABP at T2-4,and IMA at T2,3 were significantly decreased (P＜0.05),and the pathological changes of myocardial tissues were significantly reduced in group P.Conclusion Ischemic postconditioning can reduce myocardial injury in the patients undergoing cardiac valve replacement under CPB.

To study the effects of different pH HEPES-KH reperfusate solution on immature myocardial protection, isolated perfused Langendorff model from immature rabbit hearts were developed formed. Control group (C) was perfused only with pH 7.4 HEPES-KH solution for 90 min. Ischemia/reperfusion group (group I/R) was perfused with pH 7.4 HEPES-KH solution before ischemia or after ischemia. Experimental group (group E), after ischemia, was perfused with pH 6.8, pH 7.1 and pH 7.4 HEPES-KH solutions for 5 min, 5 min, and 20 min, respectively. The left ventricular function recovery, MWC, LDH and CK leakage, MDA, ATP content, and SOD activity were determined. Our results showed that the left ventricular function recovery, ATP content and SOD activity in group E were higher than those of group I/R (P < 0.05). MWC, MDA content, LDH and CK leakage in group E were lower than those of group I/R (P < 0.05). These findings suggested that pH paradox might be one of important mechanisms for immature myocardial ischemia-reperfusion injury, and acidic perfusate, at the beginning of reperfusion, might attenuate pH paradox and ameliorate functional recovery in isolated perfused immature rabbit hearts.

Objective To investigate the relationship between inflammatory bowel disease (IBD) activity and choroidal thickness,and evaluate the utility of a choroidal thickness measurement in assessing IBD activity.Methods A total of 100 eyes of 50 patients of IBD with different disease activity,including 23 patients of ulcerative colitis,27 patients of Crohn's disease (CD).Ninety-six eyes of 48 healthy volunteers were recruited as control group.Choroidal thickness was measured using enhanced depth imaging(EDI)optical coherence tomography.Results Compared with the subfoveal choroidal thickness (294.37 ± 35.04) μm in healthy volunteers,the subfoveal choroidal thickness (349.28 ± 76.57) μm in UC patients with severe disease activity,the subfoveal choroidal thickness (326.71 ± 59.71) μm and (354.24 ± 66.34) μm,respectively,in CD patients with moderate and severe disease activity were found to be increased significantly (all P ＜ 0.05).Conclusion Choroidal thickness should be considered as a potential marker to assess the disease activity in patients with IBD,especially in patients with CD.

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is an inflammatory lung injury induced by a variety of factors, and these diseases are associated with high rates of mortality due to the lack of effective treatments. Based on the latest research in ALI/ARDS, it is widely accepted that generalized inflammatory responses play a critical role in initiating and developing process of ALI/ARDS. We make a brief review on the immune-pathogenesis and the signaling pathways of ALI/ARDS from the perspective of inflammation, thereby helping develop novel therapeutic strategy for treatment of patients with ALI/ARDS.

Objective To evaluate the effects of ulinastatin on cardiac function in heart valve replacement patients with cardio-pulmonary bypass (CPB).Methods 120 patients received valve replacements were divided into 4 groups at random.Group U 1,preconditioning group:ulinastatin parenteral solution (20 000 U/kg) was injected into the central veins for 10 min before the ascending aorta was clamped.Group U2,postconditioning group:ulinastatin ( 10 000 U/kg) was injected into the aortic root for 5 min before the aortic clamp was opened.Group U3,combined the treatments of group U1 and group U2.Group C was served as control without using ulinastatin.The ST-T of ECG at different 8 time points was recorded from preanesthesia to the end of operation.The dosage of vasoactive agents in the 4 groups was recorded after the aortic clamp was opened.Blood samples were taken from the radial artery at 4 time points during 1O min before the ascending aorta was clamed to the end of operation for determining the serum concentration of H-FABP,IMA,CK-MB,MDA and SOD.The changes in myocardium were examined by microscope.Results The automatic reheating rate of heart in group U1,group U2,and group U3 were 70％,73％ and 90％ respectively,which were all higher than group C (33％) after the aortic clamp was opened in 3 -5 min.The scores of reperfusion arrhythmia,change of ST segments in ECG ( elevation or depression),the dosage of vasoactive drugs ( dopamine and adrenaline) and their using time,the concentration of MDA,H-FABP,IMA and CK-MB in group U1 and group U2 were ＜ than those of group C ( P ＜0.05 ),but was ＞ than those of group U3 ( P ＜0.05 ).The activity of SOD in group U1 and group U2 were ＞ than those of group C ( P ＜ 0.05 ),but was ＜ than those of group U3 ( P ＜ 0.05 ).There were no significant differences between group U1 and group U2( P ＞0.05 ).The myocardium in group C had focal coagulative necrosis.The damage of myocardium in group U3 was minor,the cytoplasm and nucleus was homogeneous,and the boundaries were distinct.Conclusion Ulinastatin parenteral solution preconditioning and postconditioning could improve heart function after valves replacement on CPB.The protective effects were not significantly different regarding ulinastati was administered into the central veins before the ascending aorta was clamped vs.it was injected into the aortic root before the aortic clamp opening.Combined these 2 administration methods and dosages could produce collaborative protection.
