Mannan binding lectin (MBL) is an innate immune mediator belonging to the collectin family known to bind to the surface of many viruses, bacteria and fungi. Many researches show that MBL is associated with many autoimmune diseases. Inflammatory bowel diseases (IBD) including ulcerative colitis and Crohn's disease are related with innate individual immunity. This article reviews the recent researches on the association of MBL with IBD.

Blank control group, model group, UVB irradiation group and low-, medium- and high-dose APS interventional groups were set up. Each medication group was given relevant medicine. MTT assay was used to determine the cell activity; GSH-Px, CAT, SOD activity and MDA content were detected by biochemical colorimetric method; contents of TNF-α and IL-6 were detected by ELISA.Results Compared with the control group, the contents of SOD, CAT and GSH-Px in the model group decreased significantly, while the contents of MDA, TNF-α and IL-6 increased significantly (P<0.05); compared with the mode group, the contents of SOD, CAT and GSH-Px in the medication groups increased significantly, while the contents of MDA, TNF-α and IL-6 were reduced significantly (P<0.01).Conclusion APS can reduce the oxidative stress injury of UVB to HaCaT cells to some extent.

Objective To study the effects of naloxone on ?-endorphin (?-EP) in plasma and on myocardial ultrastructure during myocardial ischemia-reperfusion (I/R) injury in rabbits.Methods The myocardial ischemia models and myocardial ischemia -reperfusion injury models in rabbits,by ligating the left anterior descending branch of coronary artery,were used to investigate the changes of ?-EP and ET-1 in plasma during I/R injury, and after treatment with naloxone, an antagonist of opiate receptor. 20 New Zealand rabbits were randomly assigned to 2 groups (each 10 rabbits in naloxone treatment and ischemia-reperfusion group). The bloods were taken at different times in each group. The concentrations of ?-EP and ET-1 were detected with radioimmunology method.The changes of myocardial ultrastructure in samples of myocardial ischemia,were observed through electron microscope.Rseults The levels of ?-EP were significantly improved after I/R injury compared with those before ischemia (P0.05). For ischemia-reperfusion group, most of cardiac muscles were in the contracting state, the myofibril dissolved and broke locally. The edema was found on the circumference of nucleus. For naloxone treatment group, the structure of myofibril was clear and its arrangement was in good order, and no obvious breakage was found. The contracting of myofibril, the edema of mitochondria and kytoplasm were moderating. Conclusion Naloxone may effectively control the levels of ?-EP and the synthesis and secreting of ET-1 after myocardial ischemia and during I/R injury;and reduce the injury to the myocardial ultrastructure and decrease the injury to blood vessel and myocardium.
