In recent years, remote ischemic preconditioning is found as a novel way to protect the brain, which may be achieved through nerve pathways, humoral factors or nerve-humoral interaction. The molecular mechanisms for the protection might be related to mitochondria ATP-sensitive potassium channel, mitogen-activated protection kinase, mammalian target of rapamycin, including nitric oxide synthase and cannabinoid receptors. The aim of this review is to explain the mechanism of action of remote ischemic preconditioning on brain protection, as well as the possible direction of clinical application.

Objective To discuss the mechanism of large dose methylprednisolone(MP) on cerebral protection of rats after focal ischemic reperfusion.Methods Using the Wistar rat models of focal cerebral ischemic reperfusion,we observed the effects of large dose MP before and after ischemia on the volume of middle cerebral after infarction and the change of cerebral water content,meanwhile the pathological change of brain tissue was observed.Results Compared with the control group, the volume of middle cerebral after infarction in MD treatment group was remarkably reduced before and after ischemia (P 0 05 ). From the control group but not the MP treatment group, we found cerebral infiltration of macrophages from the histopathology of rat brain tissues.Conclusion Large dose MP might improve ischemic brain injury,the mechanism related to reducing volume of cerebral infarction and inhibited the infiltration of macrophages in the rat brain tissues.

Objective To investigate the role of macrophage migration inhibitory factor (MIF) gene polymorphisms in adult onset Still's disease(AOSD).Methods Plasma MIF levels were measured by enzymelinked immunosorbent assay (ELISA).Genomic DNAs were collected from patients and controls.The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay and short tandem repeat genotyping were used to detect the polymorphisms of MIF gene promoter.The -173 G/C SNP and -794 CATT repeat genotype and allele frequencies between patients and controls were capared using pearson's Chi-square test.The non-parmetric Mann-Whithey U test was conducted to compare MIF expressin between cases and controls.Results Plasma MIF levels were significantly higher in AOSD (119±113) ng/ml than those in controls (55±29) ng/ml (P＜0.01).Individuals with -173 * C allele (OR=1.776; 95％CI 1.101-2.864; P=0.017) or -794 *5-CATT allele (OR=1.81;95％CI 1.27-2.58; P=0.001) were at increased risk for AOSD.Conclusion The MIF gene polymorphisms are associated with AOSD.

Objective To observe clinical efficacy of laparoscopy combined with gonadotropin-releasing hormone agonist (GnRH-a ) in the treatment of endometriosis (EMs).Methods 158 patients who underwent laparoscopic surgery and were diagnosed endometriosis in our hospital during Sep.2010 to Dec.2010 were chosen and divided into three groups:control group were treated with pure laparoscopic surgery,group A were treated with laparoscopic surgery and follow-up GnRH-a medication,and group B were treated with laparoscopic surgery,follow-up GnTH-a medication and add-back therapy.The total effective rates,recurrence rates,the changes of hormone levels before and after the treatment and adverse reaction rates after treatment were compared and analyzed to evaluate the efficacy of different treatments.Results The total effective rates of group A and group B (84.6%,86.2%) were significantly higher than that of control group (58.3%),and the difference was statistically significant (P=0.032,P=0.032).The recurrence rates of group A and group B (15.4%,13.8%)were significantly reduced compared with that of control group (41.6%)(P=0.012,P=0.012).The hormone levels decreased dramatically after treatment in three groups.The adverse reaction rate of group B was apparently reduced compared with that of group A,and the difference was statistically significant (P=0.001 ).Conclusion Laparoscopy combined with GnRH-a medication was a safe and effective treatment for endometriosis.The application of GnRH-a after laparoscopy can significantly increase the total effective rate of the operation and reduce the postoperative recurrence rate.For the patients who need to take long-term GnRH-a treatment,add-back therapy need to be given to decrease its adverse reaction and recurrence rate,or to delay its recurrence,thus could improve patients' living qualities significantly.
