Adenosine is an endogenous purine uncleoside released by cells as part of the normal metablic mechinary. During inflammation, massive ATP degradation increases the local adenosine concentration to the micromolar range, at the range, adenosine extert potent antiinflammatory rale. In vivo or in vitro experiments, the addition exogenious adenosine, its analogues and inhibition of its degradation attenuate injury of animal models of inflammation. Antiinflammatory mechinasms involve in;(1)Adenosine inhibites neutrophil function in vitro, including chemotaxiz, adhesion, phogocytosis, and oxygen radical generation. (2) Decrease the expression of collagenase, and reduce the amount of collagenase. (3)Blocking neutrophil adhesion to the endothelium mediated by L-selectin and ftrEategrin. (4)inhibition activated humanmonocytes and macrophage secreting cytokins. (5) Adenosine enhances IL-10 secretion by human monocytes. (6)inhibition of immune response and so on. Relation with nonsteroidal antiinflammatory drugs (NSALDs) includes:(1)MTX and SASP inhibit the activity of 5-aminoimidazole-4-carboxam-ide ribonucleotide (AICAR) transformylase resulting in increased local adenosine concentraton. (2) Azathioprine and its potential metabolite inhibits adenosine kinase, diminish AMP formation by adenosine. In conclusion, the existance of a novel class of antiinflammatory agents, affects adenosine metabolism and may be a useful antiinflammatory drug as well.

Sulfonylureas are one of the major oral drugs for the treatment of type 2 diabetes mellitus.Studies in recent years have shown that such drugs have the effect of independent of reducing blood sugar on ischemic stroke.This effect is mainly associated with the combination of sulfonylurea receptor 1 (SUR1) to regulate of ATP-sensitive non-selective cation channels.

Objective To study the mechanism of toxicity of methylmercury on primary cultured SD rat astrocyte.Methods Treat primary cultured SD rat astrocyte with methylmercury.Determine the level of cyto-oxidation redoxin with High Performance Liquid Chromatography(HPLC).Western-blot was applied to examine the protein expression of nuclear factor erythroid 2 related factor 2(Nrf2).Results With the increase of the concentration of methylmercury,the redoxin level of astrocyte was apparently decreasing.When the concentration of methylmercury was at a low level,the expression of Nrf2 was increasing with the increase of the methylmercury concentration.When the concentration of methylmercury was at a high level,the expression of Nrf2 was decreasing with the increase of the methylmercury concentration.Conclusion The toxicity of methylmercury on primary cultured SD rat astrocyte can be realized through altering the function of GSH and Nrf2.

Objective To assess clinical efficacy and safety of linezolid in treating postoperative intracranial infec-tion after neurosurgery operation,and provide clinical basis for the treatment of postoperative intracranial infection. Methods From January 2011 to December 2012,clinical data of 51 neurosurgery patients receiving linezolid for trea-ting postoperative intracranial infection were collected,changes in symptoms,temperature,cerebrospinal fluid (CSF)bacterial culture,as well as white blood cell (WBC)count,protein and glucose in CSF before and after therapy were compared,clinical efficacy and safety of linezolid in the treatment of postoperative intracranial infection were assessed based on the diagnostic criteria for intracranial infection.Results After linezolid treatment,30 cases of postoperative intracranial infection were cured,and linezolid was effective in 1 2 cases,improved in 5 cases,and ineffective in 4 cases,total effective rate was 92.16%.Of 47 cases with effective therapy,the mean therapy day were 12.5 d (2-27 d),11 of whom isolated gram-positive bacteria from CSF before therapy,and CSF culture were all negative after linezolid therapy.Conclusion Linezolid is effective for treating intracranial infection caused by Staphylococci,Enterococci and other gram-positive bacteria which failed to response to vancomycin therapy.

Objective To study the effect of extracellular signal-regulated kinase1/2 (ERK1/2)inhibitor U0126 on matrix metalloproteinase-9(MMP-9)in brain tissue after subarachnoid hemorrhage(SAH)in rats and to investigate the action mechanisms of ERK1/2 and M M P-9 in blood-brain barrier(BBB)injury and brain edema after SAH.Methods Seventy-two male Sprague-Dawley rats were randomly divided into four groups:SAH model,sham operation,U0126 intervention,and vehicle groups.A SAH model was induced by injection of autologous blood into cisterna magna once.The dry-wet weight method was used to detected brain tissue water content in order to evaluate cerebral edema.BBB permeability was evaluated by the Evans blue extravasation method.The immunohistochemical method was used to detect the expression of MMP-9 and phosphorylated ERK1/2.Results The expression of phosphorylated ERK1/2 and MMP-9 was lower in the sham operation group.The expression of both was up regulated at 24 hours after SAH.The brain water content and Evans blue content also increased.U0126 treatment decreased the phosphorylation of ERK1/2 and the expression of MMP-9,improved the BBB permeability,and alleviated brain edema.Conclusions MMP-9 is involved in the pathophysiological processes of early BBB injury and brain edema aft er SAH.ERK1/2 pathway may play a vital role in the expression of MMP-9.U0126 may protect BBB and reduce brain edema after SAH by inhibiting the phosphorylation of ERK1/2.

Objective To observe the therapeutic effect of thymosin alpha 1 on patients with chronic obstructive pulmonary disease.Methods 60 patients with chronic obstructive pulmonary disease were divided into two groups at random.The two groups were given conventional treatment,and the treatment group was received thymosin alpha 11.6 mg hypodermic injection,1 every other day for 4 weeks,since then 2 times/week for 5 months.All patients were followed for 6 months,clinic every 2 weeks,1 follow-up,evaluation of clinical condition.In two groups,before treatment and 6 months after treatment the blood samples were collected for the measurement of the blood CD3,CD,and CD8 levels.Results In the treatment group,the number and days of patients with acute exacerbation were significantly lower in comparison with those of the control group(all P＜0.01).After treatment with thymosin alpha 1,blood CD4 and CD4/CD8 levels were significantly increased(all P＜0.01).Conclusion Thymosin alpha 1 had a good protection effect for the acute exacerbation of chronic obstructive pulmonary disease by incresing body cellular immune activity.

Objective To study the effect of cognitive dysfunction of gangliosides on in the treatment of the patients with traumatic brain injury intraoperative and postoperative. Methods From February 2015 to August 2016, 100 patients with cognitive dysfunction after operation were randomly divided into two groups, the control group and the experimental group, 50 cases in each group. The control group were received routine treatment, including medication, brain rehabilitation, and dehydration and intracranial pressure reduction. At this basis, the experimental group were treated with gangliosides. The clinical indexes in the experimental group and the control group were compared and analyzed. Results The cure rate was 90% in the experimental group, and 54% in the control group. The difference in the two groups has statistically significant (P<0.05). Before treatment, there was no significant difference of the MMSE in the two groups. After treatment, the MMSE score in the experimental group was (28.34 ± 4.12) points, and the score of MMSE in the control group was (22.19 ± 5.49) points. The difference in the two groups has statistically significant (P<0.05). Conclusion The effect of cognitive dysfunction is better which ganglioside was used on the treatment of the patients with traumatic brain injury intraoperative and postoperative, and the cure rate is higher. It has the significance of further popularization and application.
