Objective To explore the relationship between the structure and function of galectin-3， lipid metabolism disorders， and investigate the expression of galectin-3 in the occurrence and progress of lower limb arteriosclerosis block disease. Methods Related articles were reviewed. Results Galectin-3 participates in inflammatory reaction and lipid metabolism disorders， regulates the cell growth， differentiation， adhesion， apoptosis， and angiogenesis， and palys a role in the occurrence and progress of arteriosclerosis obliterans. Conclusion Galectin-3 is correlation with the occurrence， progress， and the prognosis of arteriosclerosis obliterans.
ObjectiveTo investigate the prevalence of chronic obstructive pulmonary disease (COPD) with lipid metabolism disorders patients in Chengdu. MethodsWe randomly selected four communities from urban and rural areas in Chengdu between February and December, 2010, with multistage cluster random sampling method; 1 931 residents aged from 40 to 70 received special questionnaire from the BOLD Study, lung examination, blood biochemical examination, and physical examination. ResultsThe prevalence of COPD was 60.26% (91/151) with dyslipidemia; while non-COPD was 68.17% (972/1 428), and the difference was significant (P<0.05), in which the most obvious difference is triglycerides (TG). The prevalence of COPD was 6.62% (10/151) with underweight; while non-COPD was 4.97% (71/1 428), and the difference was significant (P<0.001). The prevalence of COPD was 21.19% (32/151) with abdominal obesity; while non-COPD was 30.81% (440/1 428), and the difference was significant (P<0.05). ConclusionThe prevalence of COPD with lipid metabolism disorders is lower than which with non-COPD in Chengdu. It provides an evidence for the nutrition support therapy in the treatment of COPD.
