ABCG1 plays a crucial role in maintaining intracellular sterol homeostasis , but its exact function in atherosclerosis is still unclear .Eluci-dation of the mechanisms of ABCG 1 in intracellular sterol flux will provide important information that may link ABCG 1 to diseases of dys-regulated tissue lipid homeostasis .This review focuses on recent advances of ABCG 1 and its roles in cholesterol transport .

BACKGROUND: It is thought in traditional Chinese medicine that dogday moxibustion (DDM) has good clinical effect in treating bronchial asthma. Study of its influence on soluble cellular adhesion molecules in patients with bronchial asthma can help to well understand its mechanism.OBJECTIVE: To observe the effect of dog-day on soluble cellular adhesion molecules in patients with bronchial asthmaDESIGN: Self-control, case-control observationSETTING: College of Acupuncture and Manipulation and Clinic of the Department of Acupuncture and Moxibustion of the First Affiliated Hospital, Guangzhou University of Traditional Chinese Medicine.PARTICIPANTS: Totally 28 patients with bronchial asthma receiving dog-day moxibustion in the Clinic of the Department of Acupuncture and Moxibustion, First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine from July to August 2004 were set as dog-day moxibustion group, and 10 concurrent health volunteers were set as normal control group.METHODS: According to the principle of "treating winter diseases in summer", the Chinese medicine which consists of such herbs as Baijiezi(Semen Sinapis Albae ), Mahuang(Herba Ephedrae ), Xixin (Herba Asari ),Gans ui (Radix Kansui ), Yanhu (Rhizoma Corydalis ) was stuck on the points such as Feishu, Dingchuan, Fengnen, Bailao, Shenshu. Point selection was at the two sides, and a lumpy salve was stuck on the point with adhesive tape. Three to six hours for adult and one to two hours for children in each sticking duration; and the operation was respectively done on the first (July20), second (July 30) and third (August 9) dog-day.MAIN OUTCOME MEASURES: Short-term effect 3 months later was observed, the levels of soluble cellular adhesion molecules and IgE were assayed before and 10 days after treatment, and comparison with normal control group was performed. The indexes of the patients before treatment were performed Pearson correlation analysis.RESULTS: Twenty-eight patients and 10 healthy persons all entered result analysis. [1] Intercellular adhesion molecule-1 level was significantly higher before treatment in dog-day moxibustion group than that after treatment in the dog-day moxibustion group and that in the normal control group [(281.39±64.58 ), (256.95±44.22), ( 194.30±39.05 ) μg/L,P ＜ 0.01].[2]Vaso-cellular adhesion molecule-1 level was significantly higher before treatment in the dog-day moxibustion group than that after treatment in the dog-day moxibustion group and that in the normal control group [(234.79±89.75), (185.80±84.41), (128.85±51.28)μg/L,P ＜ 0.01]. [3]IgE level was significantly higher before treatment than that after treatment in the dog-day moxibustion group and that in the normal control group [(482.61±123.43), (418.96±134.18), (161.53±43.64)μg/L,P＜ 0.01]. [4]Pearson correlation analysis result: Intercellular adhasion molecule-1 level is significantly positively correlated with IgE and vascular intercellular adhesion molecule-1 level (r =0.641,0.449 ,P ＜ 0.01,0.05). [5]Effect: Total effective rate was 93% (26/28)in the treatment of bronchial asthma with dogday moxibustion . The type of the symptoms, with blister or not, course of disease and condition of disease had no significant influence on effect (P＞ 0.05).CONCLUSION: Dog-day moxibustion may effect through inhibiting the expression of adhesion molecule or inhibiting leukocyte to adhere endothelial cell directly so as to reduce the infiltration of inflammatory cells.

OBJECTIVE To provide references for clinical diagnosis of catheter-related bloodstream infections(CRBSIs) and focus on studying the spectras of pathogenic bacteria and the drug sensitiveness. METHODS A total of 137 patients enrolled from Jan 2005 to Dec 2007 in our hospital with positive catheter cultures were admitted to our retrospective analysis.Pathogenic bacteria,contaminant bacteria and the drug sensitiveness of main pathogenic bacteria were analyzed.

Skeletal muscle extracellular matrix (ECM) is the microenvironment for muscle cells to survive and function. Changes in ECM components and structure directly affect the activity and function of muscle cells. Pathological remodeling occurs to skeletal muscle ECM in insulin resistance, including collagen deposition, hyaluronan accumulation, activation of membrane protein integrin signaling path-way, and the imbalance of matrix metalloproteinases and tissue inhibitors of metalloproteinases, while all those would impair the tissue insu-lin sensitivity.
