Objective To study the changes of apoptosis in brain after traumatic injury(TBI)treated with exogenous vascular endothelial growth factor(VEGF)gene therapy in oder to find out the role of exogenous VEGF gene in protectiog brain tissue.Method The injurea cerebral cortex from the rat models of brain with traumatic injury was injected with adenovirus(adenovirus,Ad)as the carrier of VEGF-165 gene(Ad-VEGF-165 Gene).RT-PCR and Western blot were used to detect the expression of VEGF mRNA and VEGF protein in the brain 6 h,24 h,3 d,7 d and 14 d after injury,and apoptosis in the injured location of brain was also detected by TUNEL successively after Ad-VECF-165 gene therapy.Results With exogenous Ad-VEGF-165 applied to the locally injured brain tissue after injury,VEGF mRNA and VEGF protein showed consistent expression and their expressions were significantly higher than those in trauma group and vehicle control group.Compared with the trauma group.the apoptosis in the gene therapy group 24 h,3 d and 7 d after injury presented a.significant reduction,and had close relationship with VEGF.(Control group:4.17±0.73;TBI group,24 h:47.18±6.01,3 d:79.44±11.23;TBI+VEGF group.24 h:28.72±5.31,3 d:54.18±7.66;P＜0.05).Conclusions The exogenous VEGF gene therapy administered to have protective effects on the local brain tissue in rats with traumatic injury in a certain time.

Delayed cerebral vasospasm is the leading cause of death in patients with subarachnoid hemorrhage. A good in vivo animal model of cerebral vasospasm after subarachnoid hemorrhage helps to understand the occurrence, development of this cerebral vasospasm, and the complicated and various pathophysiological mechanisms. It will provide important information for clinical interventions

Objective To observe the therapeutic effect of intermittent pneumatic compression pump to prevent deep venous thrombosis for patients after hip surgery. Methods A total of 104 bedridden patients 72 hours after hip surgery were divided into the treatment group and the control group. Patients in the control group were administrated routine antithrombotic drugs and active functional exercise. While patients in the treatment group were provided with intermittent pneumatic compression pump as assistant based on the routine treatment and active functional exercise. The condition of deep venous thrombosis in the two groups were observed. Results Intermittent pneumatic compression pump had remarkable therapeutic effect on preventing deep venous thrombosis of lower extremity for patients lying in bed over 72 hours after hip surgery. Conclusions Intermittent pneumatic compression pump as an assistant treat -ment based on the routine antithrombotic therapy contributes to prevent deep venous thrombosis of lower extremity for patients lying in bed over 72 hours after hip surgery.

OBJECTIVE:To explore the general patterns and characteristics of the adverse drug reactions(ADR)induced by acyclovir.METHODS:52 acyclovir-induced ADR reports(60 cases)published in China Hospital Knowledge Database from 1994 to 2006 was analyzed statistically.RESULTS:The ADR induced by acyclovir were more often occurred in patietns aged from 31 to 60,with 41.67% appearing within 10～60 min after drug use.The clinical presentation was complex and diverse,which involved different systems and organs,predominantly the lesion of renal function.CONCLUSION:Clinician and pharmacists should attach great importance to Acyclovir-induced ADR in clinical practice and stick to rational drug use.

A total of 100 neurons were recorded from the nucleus raphe magnus (NRM), of which 59 were identified as noxious-exaitation neurons; 30 as noxioes-inhibition neurons; 5 as non-noxious neurons; and 6 as non-responsive neurons Seventy neurons were further tested with electro-acupuncture (EA). 69.77% of the noxious-excitation neurons were excited and 68.42% of the noxious -inhibition neurons inhibited by EA. Stimulation of the periaqueductal gray (PAG) could activate the majority of the EA-response neurons. Systemic morphine could also affect the EA-response neurons through the following three patterns: excitation, inhibition and no-effect. No signilicant correlation between the response patterns of EA and morphine was found. The results indicate that the effect of NRM in EA and morphine analgesia is only partially overlapped.
