RESUMO
OBJECTIVE@#To explore the possibility of 10-23DNAzyme becoming a new gene therapy for laryngeal carcinoma treatment at the cell level.@*METHOD@#Thiosthorothioate 10-23DNAzyme specific to eIF4E gene mRNA 1059 was designed and synthesized, and its inhibition effects on the expression of eIF4E gene in Hep-2 cells were observed.@*RESULT@#The expression of eIF4E gene was remarkable depressed after Hep-2 cells was transfected by DNAzyme. The level of inhibiting eIF4E in hep-2 cells transfected by DNAzyme was lower than that by only lipofectamine 2000 transfected and Hep-2.@*CONCLUSION@#The expression of eIF4E gene in Hep-2 cells 10-23DNAzyme can be highly blocked. It is a specific and effective gene therapeutic means.

OBJECTIVE To summarize the clinical experience of endoscopic thyroidectomy via suprasternal approach. METHODS Endoscopic thyroidectomy via suprasternal approach was performed in 35 patients with ultrasonic scalpel. RESULTS Operations were successfully performed in 35 patients. The mean operation times were 130 (105～190) minutes in 24 cases with subtotal lobectomy and 4 case with total lobectomy, 60 (50～70) minutes in 2 cases with isthmectomy, 228 (185～270) minutes in 2 case with bilateral subtotal lobectomy, 163 (140～215) minutes in 3 case with subtotal lobectomy and the contralateral ademona resection .The bleeding during operation was 5 to 40ml and the average hospital stay time was 4 (3～5) days. CONCLUSION Endoscopic thyroidectomy via suprasternal approach is a safe way with good cosmetic value.
RESUMO
Objective :To sutdy the effects of Shenyanling on chronic glomerulonephritis in rabbits. Meth-ods:Rat glomerular base membrane (GBM) and Freund＇s adjuvant were injected into rabbits subcuta-neously or intracutaneously to build the Steblay nephritis model. Shenyanglin was administered. Kidneyfunction was evaluated by measuring urine protein,urea nitrogen ,creatinine ,albumin and globulin in serumas wellas the histopathological changes of kidney were observed. Results:Compared with model group,Shenyanling could dose-dependently reduce the level of the urine protein,urea nitrogen and creatinine inserum and the damage of kidney;while,the serum albumin could maintain the normal level (P＜0.05).Conclusion:Shenyanling has protective effects on chronic glomerulonephritis in rabbits.
