Objective To explore the neuroprotective effect of dexmedetomidine ( Dex) in rats ex-posed to focal cerebral ischemia/reperfusion ( I/R) induced by middle cerebral artery occlusion ( MCAO) and the possible mechansims.Methods Adult male Sprague-Dawley rats were subjected to MCAO for 90 min followed by reperfusion for 24 h and Dex ( 15μg? kg-1 ) was infused through the left femoral vein im-mediately after the onset of MCAO.The PI3K inhibitor LY294002 ( LY,10 mM,10 μl) or eNOS inhibitor L-NIO ( 1 mg? kg-1 ,10μl) was intracerebroventricular administered before ischemia using a microinjecton. The neurological deficit score,brain edema,cerebral infarct volume,and neuron survivals were evaluated after 24 h of reperfusion.The expression of p-Akt ( Ser473) and p-eNOS ( Ser1177) in the ischemic hemicere-brum was detected by Western Blot.Results Compared with I/R group,the neurological deficit score,cere-bral infarct volume,and the degree of brain edema were significantly reduced in the rats treated with Dex ((2.3±0.4) vs (3.9±0.6),(19.3±3.5)%vs (40.5±5.4)%,(61.8±8.1)%vs (76.3±8.5)%,all P<0.05)re-spectively,and the number of survival neuron in the hippocampal CA1 and cortex was significantly increased ((136.5±15.8)/mm vs (53.5±7.9)/mm,(253.8±26.4)/mm3vs (112.5±14.6)/mm3,all P<0.01) respec-tively.The neuroprotection in DEX group was significantly inhibited by LY and L-NIO ( P<0.05) .In addi-tion,the expression of p-Akt and p-eNOS in the ischemic hemicerebrum was markly reduced in LY group compared with that in DEX group ((3.94±0.45) vs (0.85±0.21),(2.14±0.25) vs (0.79±0.29),all P<0.01) ,while there was no significant difference in the expression of p-Akt in the ischemic hemicerebrum be-tween L-NIO group and DEX group ((3.76±0.33) vs (3.94±0.45), P>0.05).Conclusion Dex can reduce cerebral injury in rats exposed to focal I/R,which is mediated by the activation of PI3K/Akt-eNOS pathway.

Objective To investigate the of dural reconstruction plates for treatment of humeral intercandylar fracture.Methods The 52 cases with humeral intercandylar fracture were treated with dural reconstruction plates internal fixation.Watched the clinical efficacy Postoperative in outpatient,and guide early exercise of elbow.Result Using Elbow Scoring Standard System to assess:16 cases of C1,excellent and good in 14 cases,fair in 2 cases,and 87.5％ excellent and good results were obtained.Twenty-four cases of C2,excellent and good in 20 cases,fair in 4 cases,and 83.3％ excellent and good results were obtained.Twelve cases of C3,excellent and good in 6 cases,fair in 2 cases,and poor in 4 case,and 50.0％ excellent and good results were obtained.Fifty-two cases were followed up,excellent and good in 40 cases,fair in 8 cases,and poor in 4 case,and 76.9％ excellent and good results were obtained.Conclusion Dural reconstruction plates internal fixation was the relatively effective method for treatment of humural intercandylar fracture.

The basic physiological function of anti-arrhythmic drugs is affects myocardial cell membrane ion channels. Change the ion flow and affect cell electrophysiological properties, change the conduction velocity, eliminate retrace, inhibit autorhythmicity and trigger events, inhibit the occurrence of arrhythmia, but will trigger a new activities, new retrace, produce new arrhythmia. In recent years, with the improvement of the theoretical system of traditional Chinese medicine and the production of new research methods, Chinese medicine treatment of arrhythmia has a new development. This article summarized the recent decades of which Chinese medicine monomer anti-arrhythmic drugs that had been proved by the influence of monomer anti-arrhythmic drugs, lists the differents traditional Chinese medicinal materials which chemical composition and the effective of the anti-arrhythmic effects, shows the unique advantages of Chinese medicine in the aspect of anti-arrhythmic, and points out that the current Chinese medicine in anti-arrhythmic (monomer) existing problems and solutions.

The contents of gallic acid, catechin, albiflorin, paeoniflorin, benzoic acid and paeonol extracted in different growth years, collecting season and of different parts of Paeonia lactiflora were determined. The results showed that the contents of catechin and paeoniflorin in Paeonia lactiflora collected in autumn are the highest, and the contents of benzoic acid was lower than that of those collected at other time. The longer is the age of Paeonia lactiflora, the higher is the contents of catechin and paeoniflorin. The contents of catechin and paeoniflorin in the root of Paeonia lactiflora were higher than those in other parts of the plant. There is a certain content of paeoniflorin in the leaves of Paeonia lactiflora. Judging from the result, paeoniflorin is synthesized in the leaf and then transported to the root. Catechin is not synthesized in the leaf, but mainly in the root. Paeonia lactiflora should be collected in autumn, and immature plant should not be collected.
