ABSTRACT
Tanshinone ⅡA is one of the main effective components in Salviae Miltiorrhizae Radix et Rhizoma. It plays a role in the resistance to atherosclerosis by participating in anti-inflammatory in vascular wall, such as the regulating endothelial cell apoptosis and correcting lipid metabolism disorder. This article summarized recent researches of the basic role of tanshinone ⅡA in the resistance to atherosclerosis and provided references for clinical application of antiatherosclerotic effect of tanshinone ⅡA.
ABSTRACT
Objective To investigate the therapeutic effect of stage treatment of severe complicated injuries in palmar forearm and wrist.Methods From March 2008 to Novemler 2011, eleven cases with skin lost combined with fracture and lost of flexor tendon, ulnar radial arteries, median and ulnar nerves,and some of them had fracture of ulnar and radius were treated in the first stage with vacuum sealing drainage after emergency debridement and tissue repair. Secondary microsurgical repair was performed after the VSD was removed. The lost of median and ulnar nerves was repaired with transplantation of sural nerve,and the wound was repaired with free flaps and complex tissue flaps. Results Eleven cases were treated with vacuum sealing drainage for 7 to 10 days.Infections were under control,wound areas reduced and most wound areas were covered by granulation tissues.Flaps and skin grafts were survived.After postoperative follow-up for 3 to 36 months (average 13 months),three cases was received flexor tendolysis.As result,the blood circulation of hand was good, the sensor of injured nerve was higher than S3, and there was a good functional rehabilitation of hand muscles. Conclusion Using vacuum sealing drainage after emergency debridement and tissue repair, there was a good repairing effect of secondary repair with flaps and skin grafts for severe complicated tissue defect in palmar forearm and wrist,and it is an effective choice of operation.
ABSTRACT
Toll-like receptor( TLR )is a newly discovered important innate immune receptor and signal transduction transmembrane receptor.By the TLR in the surface of immune cells,body can recognize conserved pathogen-associated molecular patterns,to stimulate the production of cytokine,increased costimulatory molecule expression of antigen-presenting cell,activating T cells,establishing a closely-linked bridge between the innate immunity and acquired immunity.TLR9 is a member of Toll-like receptor family,mainly identify viral or bacterial DNA containing unmethylated CpG dinucleotides.Studies have showed that TLR9 is in the immune system's recognition of EB virus,and it plays an important role in the infection and transformation of the EB virus.This paper reviews the studies of the interaction of TLR9 with EB virus.
