Stroke is one of the main causes of death in the world, of which more than 85% are acute ischemic stroke, and reperfusion therapy is its main treatment. Studies have shown that the neutrophil to lymphocyte ratio (NLR) is associated with the efficacy, safety and outcome of the reperfusion therapy. This article reviews the predictive role of NLR in patients with ischemic stroke receiving reperfusion therapy.

Objective To explore the possible mechanism of over expression of P-glycoprotein(Pgp) in brain tissue and peripheral blood in refractory epileptic rats with amygdale kindled by electricity and kainic acid,and compare the expression tendency of Pgp in brain tissue and peripheral blood of the different ways to establish refractory epileptic rats models.Methods The models of refractory epileptic rats were made by electrical kindling and kainic kindling in amygdale.Group A was for amygdale-electrical-kindling rats(n=12),group B was for amygdale-kainic-kindling rats(n=12),group C was implanted electrode without kindling and Carbamazepine was given by gavage(n=8),group D was injected saline in amygdale and Carbamazepine was given by gavage(n=8),group E was implanted electrode without kindling and saline was given by gavage(n=8) and group F was injected saline in amygdale and saline was given by gavage(n=8).The expression of Pgp in brain tissue and peripheral blood was detected by immunohistochemistry in each group.Results The expression of Pgp in brain tissue and peripheral blood of rats in group A and B were both much higher than those in the other groups and there were statistical differences(all P

BACKGROUND:The whole-kidney acelular matrix scaffold in rats prepared by perfusion method is proved to have goodin vitro biocompatibility, butin vivo biocompatibility is stil unclear. OBJECTIVE:To produce a whole-kidney acelular matrix scaffold in rats by perfusion method and to evaluate the in vivo biocompatibility of the scaffold. METHODS:The whole-kidney acelular matrix scaffold in Wistar rats was prepared by perfusion method and evaluated with the folowing tests. (1) Acute toxicity test: mice were subject to intraperitoneal injection of whole-kidney acelular matrix scaffold extract liquid, normal saline and phenol. (2) Hemolytic test: Anticoagulant blood samples from New Zealand rabbits were mixed with whole-kidney acelular matrix scaffold extract liquid, normal saline and distiled water, respectively. (3) Pyrogen test: Whole-kidney acelular matrix scaffold extract liquid was injected into the ear vein of New Zealand rabbits. (4) Intracutaneous stimulation test: Whole-kidney acelular matrix scaffold extract liquid was injected subcutaneously into New Zealand rabbits for observing whether there was a skin stimulus response. (5) Subcutaneous implantation test: The whole-kidney acelular matrix scaffold was implanted subcutaneously into the back of New Zealand rabbits. RESULTS AND CONCLUSION:There was no cel residual in the whole-kidney acelular matrix scaffold preparedby perfusion method, and no acute systemic toxicity, hemolytic reaction, pyrogen response, and skin stimulus respons, indicating the scaffold has a good histocompatibility in the rabbits. These findings suggest that the whole-kidney acelular matrix scaffolds in Wistar rats prepared by perfusion method have goodin vivo biocompatibility.

Objective To investigate the effect of acupuncture at the primary points of the three yin meridians of the foot on blood pressure in an animal model of high/low blood pressure and explore the specific effect of the meridian points-the primary points of the three yin meridians of the foot.Methods The study included the parts of hypertension and hypotenstion. Both parts were allocated to the primary points of the three yin meridians of the foot, non-acupoint, model and blank groups, six rats each. Except the model and blank groups, all the groups were given acupuncture treatment for seven consecutive days. Blood pressure was measured after the completion of treatment. Five consecutive measurements were made in each rat. Mean values of blood pressure were taken.Results For the part of hypertension, blood pressure at each time point was higher in the acupuncture groups than in the blank control group and lower than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a hypotensive effect. The hypotensive effects of Taichong and Taixi were better than those of Taibai and the non-acupoint (P<0.05). The hypotensive effects of Taichong and Taixi were equal (P>0.05). The hypotensive effect of Taibai was equal to that of the non-acupoint (P>0.05). For the part of hypotension, blood pressure at each time point was lower in the acupuncture groups than in the blank control group and higher than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a pressor effect. The pressor effect was worse in the the non-acupoint group than in the primary points of the three yin meridians of the foot group (P<0.05). The pressor effects of Taibai and Taixi were equal but worse than that of Taichong (P<0.05).Conclusions Acupuncture at the primary points of the three yin meridians of the foot has a specific bidirectional regulating effect on blood pressure. Of them, point Taichong produces a best bidirectional regulating effect on blood pressure.

Objective To explore the value of endoscopic retrograde cholangiopancreatography (ERCP)in the treatment of chronic pancre-atitis (CP).Methods Thirty patients with CP who underwent ERCP from January 2008 to December 2012 were retrospectively analyzed. Serum amylase levels were determined before and at 24 hours after surgery.The reduction in abdominal pain was dynamically evaluated be-fore and after treatment.A follow -up of patients with steatorrhea and anxiety was performed.Regular reexamination using abdominal ima-ging or ERCP was performed to identify pancreatic lesions and conditions of pancreatic duct stents.Results All patients were successfully treated by ERCP and had pancreatic duct stents placed.The remission rate of abdominal pain reached 83.3% at 72 hours after surgery.One patient was assigned to surgery due to insignificant improvement in symptoms,and the case -fatality rate after surgery was 0.Conclusion ERCP is an effective method in the treatment of CP,which has the advantages of being safe,effective,and minimally invasive.

Objective To explore the effects of physiological ischemia training (PIT) on the function of endothelial progenitor cells.Methods Eighteen male New Zealand rabbits (2.5 ± 0.5) kg were divided into 3 groups:a sham operation (SO) group,a myocardial ischemia (MI) group and a MI ± physiological ischemia training (MI ± PIT) group.The PIT was modeled by ischemic isometric contraction of gastrocnemius muscle induced by electric stimulation (40 Hz,1 ms,40％ maximum current strength),and the MI was modeled by implantation of a water balloon to occlude the left ventrical branch of the heart.The experiment was conducted for 4 weeks.Before and after the experiments,the ability of mobilization and adhesion of endothelial progenitor cells were detected,the number and the capillary density were counted.Results Post-experiment,compared with groups SO and MI,PIT group significantly improved the ability of mobilization (151 ± 16 cells/HPF,P ＜ 0.01) and adhesion (17.8 ± 2.8 cells/ HPF,P ＜ 0.05),increased the circulating amount (P ＜ 0.05) and capillary density (824.0 ± 106.6 /mm2,P ＜ 0.05).Pearson analyze showed that there was positive correlation between circulating EPCs and capillary density.Conclusion Physiological ischemia training could improve EPCs mobilization and function,resulted to neovascularization in the ischemic heart tissues.
