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.

Objective: To analyze the hospitalization expense and management status of severe mental illness, and to provide evidences for rational controls of medical expenses and the management of the patients. Methods:Collecting patients with severe mental illness from 2005 to 2012, analyzing the changing trends of hospitalization cost and management status with descriptive analysis, and use multiple linear regression to analyze the influence factors. Results: The average stay is 51 days, average medical costs by person and by day are RMB 8 319.69 and 169.02; treatment costs, drug costs and bed care costs are the main proportion. The medical costs were significantly affected by prolonged days of hospitalization, age, numbers of hospital admissions, nursing level and admitting diagnosis. The largest proportion of management system is schizophrenia, which counted 74.03% of current patients and the poverty incidence rate is 50.62%. Conclusions: Increasing the financial compensation to patients with severe mental illness, shorting hospital stay, strengthening the screening of patients with severe mental illness and incorporated into the management system would help to reduce the economic burden of the patients.

Strain QJ16,one of some methanotrophic bacteria isolated from soil samples utilizing the separate device designed by our laboratory;was studied in detail and identified as one of the Genus methylomonas through 16S rDNA sequencing and comparison. The culturing and reaction conditions for methane utilization of this strain were investigated. The results indicated that the optimal conditions for the growth of strain QJ16 were methane gas as carbon source and the coexistence of NH4Cl and KNO3 as nitrogen source,the cultivation temperature of 30℃ and medium initial pH 6～7,and the optimal Cu2+ concentration of 15 ?mol/L.
