BACKGROUND:The research at home and abroad for appropriate immature myocardial cardioplegia has no breakthrough, and it may be a better mean to improve the protection effect of existing cardioplegia on immature myocardial by adding ingredients. Adenosine can reduce ischemia and neutrophil-mediated reperfusion injury, and salvia miltiorrhiza can reduce the content of ischemic myocardial lipid peroxide and increase the scavenging of myocardial cells to oxygen radical. OBJECTIVE:To investigate the protection effect of improved myocardial protection fluid containing adenosine and salvia miltiorrhiza on the heart, liver and kidney. METHODS:Sixty cases of infant open heart operation of the first time were randomly divided into three groups, 20 cases in each group. The adenosine group received the improved myocardial protection fluid added with adenosine, the combination group received the improved myocardial protection fluid added with adenosine and miltiorrhiza salvia, and the control group received the improved myocardial protection fluid in the same volume. The blood samples were taken at the time before anesthesia induction, 30 minutes after cardio pulmonary bypass beginning, 1 hour after cardio pulmonary bypass end and 24 hours after cardio pulmonary bypass end. The serum levels of the creatine kinase, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine, tumor necrosis factor-α, interleukin-6, interleukin-8 and interleukin 10 were detected. RESULTS AND CONCLUSION:The serum levels of the alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and creatine kinase in three groups were increased, but the control group was increased significantly (P<0.01), and there were significant differences between adenosine group and combination group (P<0.05);the levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 were significantly increased after operation (P<0.05). The levels of tumor necrosis factor-α, interleukin-6 and interleukin-8 in the control group were significantly higher than those in the adenosine group and combination group before induction and at the same time point (P<0.01);at 3 minutes and 24 hours after cardio pulmonary bypass, the level of interleukin-10 was increased in three groups, but the level of interleukin-10 in the adenosine group was significantly higher than that in the control group (P<0.01). The results indicate that improved myocardial protection fluid has great protection effect on immature myocardial, and can significantly reduce the serum levels of tumor necrosis factor-α, interleukin-6 and interleukin-8, promote the secretion of interleukin-10 that can inhibit inflammatory cytokine and can significantly reduce the inflammatory response caused by cardiopulmonary bypass. So the improved myocardial protection fluid has protection effect on important organs, such as heart, lung, liver and kidney.

BACKGROUND:There is lack of effective diagnostic methods for early knee osteoarthritis. Proteomics refers to the large-scale experimental analysis of proteomes from the overal level of intracel ular protein compositioon, expression and modification, based on which, we can understand protein-protein interaction and relationship, thereby revealing protein functions and cel activity patterns. OBJECTIVE:To apply the isobaric tags for relative and absolute quantitation (iTRAQ) to identify proteins differential y in serums of osteoarthritis Kel gren-Lawrence classification at each stage, and to find out potential molecular markers at each stage of osteoarthritis. METHODS:Sixty patients with knee osteoarthritis were enrol ed, and according to Kel gren-Lawrence (K-L) grading, they were subdivided into K-L 0, II and IV groups. There were 10 males and 10 females randomly selected in each group. Proteins differential y regulated in serums were identified by the stable isotopes 116, 117, 118 of the iTRAQ labeled, reversed-phase column separation, mass spectrometry and Swissport database search, after the serums were subjected to high abundance proteins depletion. Final y, we analyzed the proteins identified by using bioinformatics software. RESULTS AND CONCLUSION:Total y 169 proteins were identified through iTRAQ peptides experiments of different sample tags, Q-star mass spectrum identification and MASCOT library search. 153 proteins were identified as K-L 0 to K-L IV, 153 proteins were identified as K-L 0 to K-L II, and 145 proteins were identified as K-L II to K-L IV. iTRAQ technology may help to identify novel serum markers for early diagnosis of knee osteoarthritis, indicating iTRAQ technology for proteomics serum biomarkers of osteoarthritis study has good application prospect.

OBJECTIVE: To investigate the effect of zoledronate (ZOL) on osteoclast differentiation and bone resorption under high glucose, and the regulation mechanism of p38 mitogen activated kinase (p38 MAPK) signaling pathway in this process. METHODS: RAW264.7 cells were divided into four groups: low group, high group, low+ZOL group and high+ZOL group after induced into osteoclasts. Cell proliferation activity was determined by MTT assay. The migration of RAW264.7 cells were examined Optical microscopy. Immunofluorescence microscopy was used to observe the cytoskeleton and sealing zones of osteoclasts. After adding group 5: high + ZOL + SB203580 group, trap staining was used to identify the number of positive osteoclasts in each group. The number and area of resorption lacunae were observed by SEM. The mRNA and protein expression of osteoclast related factors were detected by real-time PCR and Western blotting. RESULTS: The cells in the 5 groups showed similar proliferative activity. High glucose promoted the migration of RAW264.7 cells ( CONCLUSIONS High glucose inhibits osteoclast differentiation and bone resorption. ZOL inhibits osteoclast differentiation and bone resorption in high-glucose conditions by regulating p38 MAPK pathway, which can be a new pathway for ZOL to regulate diabetic osteoporosis.
