Objective: To investigate the relationship between blood level of Galectin-3 and the severity of coronary lesions in patients with coronary artery disease (CAD). Methods: A total of 158 consecutive subjects received coronary artery angiography (CAG) in Yantai Yu huangding hospital were studied and they were divided into 2 groups: Control group,n=38 individuals with normal coronary artery, CAD group,n=120 patients with at least 1 coronary branch stenosis ≥ 50%. CAD group was further divided into 2 sets of subgroups:①By the number of branches involved, as Single vessel disease, n=42, Double vessels disease including LM,n=40 and Triple vessel disease,n=38.②By the quartile of Gensini score as 1st quartile group, the patients with Gensini score ≤ 18.5, 2nd quartile group,18.5 < Gensini score ≤ 45.0, 3rd quartile group, 45.0 < Gensini score ≤ 71.5 and 4th quartile group, Gensini score>71.5,n=30 in each subgroup. Blood levels of Galectin-3 were examined, and the severity of coronary lesions was evaluated by both branch numbers and Gensini score analysis. Results: Compared with Control group, the blood level of Galectin-3 was higher in CAD group,10.66 (5.81, 16.17) ng/ml vs 18.3(1.14, 2.52) ng/mlP<0.01; with the more branches of coronary lesions involved, the blood levels of Galectin-3 increased accordingly, all P <0.01. With the elevation of Gensini score, the levels of Galectin-3increased accordingly, except for the difference between the 3rd quartile group and 4th quartile group, all P <0.01.With adjusted other factors, blood levels of Galectin-3 were positively related to the number of coronary branchlesions (r =0.52, P <0.01) and Gensini score levels (r =0.17, P =0.04).Conclusion: Blood level of Galectin-3 is positively related to the severity of coronary lesions whichimplies that Galectin-3 may have potential detrimental effect on the occurrence and development of coronaryatherosclerosis.

Exposure to thermal environment is one of the main concerns for manned space exploration. By focusing on the works performed on thermoregulation at microgravity or simulated microgravity, we endeavored to review the investigation on space thermal environmental physiology. First of all, the application of medical requirements for the crew module design from normal thermal comfort to accidental thermal emergencies in a space craft will be addressed. Then, alterations in the autonomic and behavioral temperature regulation caused by the effect of weightlessness both in space flight and its simulation on the ground are also discussed. Furthermore, countermeasures like exercise training, simulated natural ventilation, encouraged drink, etc., in the protection of thermoregulation during space flight is presented. Finally, the challenge of space thermal environment physiology faced in the future is figured out.

BACKGROUND:Different mechanical stimulations may have an effect on the level of metabolism of chondrocytes, but the effect is not clear.
OBJECTIVE:To investigate expression level changes in metabolic genes that participate in cartilage cel decomposition and synthesis under compressive stress and tensile stress conditions.
METHODS:We obtained articular chondrocytes from 2-week-old Sprague-Dawley rats. Primary cultured chondrocytes were identified. Passage one chondrocytes received cyclic tensile stress and cyclic compressive stress of 3%and 7%, respectively, so as to measure articular changes in chondrocytes-related genes.
RESULTS AND CONCLUSION:When chondrocytes were subjected to cyclic tensile stress of 3%, synthetic metabolic gene col agen types I and II and proteoglycan mRNA expression levels were decreased. If 3%cyclic compressive stress was applied, proteoglycan mRNA expression levels were increased, and type I col agen mRNA expression levels were decreased (P<0.001), and matrix metal oproteinase-13 mRNA expression levels were reduced (P<0.01). When strain reached 7%, cyclic tensile stress and compressive stress could lead to a general decrease in anabolism-related genes. The former could also make matrix metal oproteinase-13 mRNA expression levels increased (P<0.05). 3%cyclic compression ratio and 3%cyclic stretch made cytoskeleton become oval. These results indicated that in vitro, proper cyclic compressive stress is beneficial to maintain the growth characteristics of articular chondrocytes in rats. Smal tensile stress can decrease the synthesis ability of chondrocytes. The effect of stress may be caused by changing the cytoskeleton.
