Objective To investigate effect of lipid emulsion on cardiac arrest induced by bupivacain intoxication.Methods Forty SD rats were randomly devided into 2 groups.Group A applied epinephrine (n=20);Group L applied lipid emulsion combinding epinephring(n=20).The rats were administered Lupivacaine 20 mg/kg.Cardiopulmonary resuscitation(CPR) was started. Epinephrine 10 μg/kg were repeated three times followed by epinephrine 10 μg/kg every 5 minutes.Normal saline 5 ml/kg and 1 ml·kg-1·min-1 were administered in group A.20% Lipid emulsion 5 ml/kg and 0.25 ml·kg-1·min-1 were administered in group L.Heart rate,blood pressure, temperature were monitored.Blood gas analysiswere checked at 5 min,30 min after restoration of spontaneous circulation(ROSC).To record the number of successful CPR,time of ROSC and epinephrine dose.Results 11 rats(55%) and 16 rats(80%) were successful resuscitated.The success rate was higher in group L than in group A.Epinephrine dose was higher in group A than in group L.There was no difference in heart rate between the two groups.Systolic blood pressure and PaO2 was higher in group L than in group A(P<0.05).Conclusion There was better effect in lipid emulsion combined epinephrine than soly epinephrine when applied in cardiac arrest induced by bupivacaine intoxication.

Objective To study the condition of postoperation complications in patients with supratentorial cerebral hemisphere gliomas,and to provide objective references for clinical classification and treatment. Methods Data of 100 patients with supratentorial cerebral hemisphere gliomas,treated surgicaly in the department of neurosurgery,gliomas center of Tiantan hospital from June 2006 to December 2007,were reviewed and analyzed.We classified postoperative complications as neurological,regional and systemic complications,and especially mainly analyzed the reasons of oceching,prevention and cure of the neurological postoperative complications.Results Through the complete preoperative evaluation in patients to choose the proper operative route,methods and technique means can improve postoperative KPS score compare with preoperative obviously ,which can achieve better operation result.Conclusion Neurosurgeon must design consummately individualization operation plan depending on patient history,neurology symptoms,physical sign,and preoperative check,and understand the operation anatomy including the pathology anatomy and function anatomy. They must foresee the postoperative complications,prevent it as far as possible,and treat it reasonable in time.

Objective To analyse the clinical characteristics,gene mutation and enzymatic activity of αgalactosidase A(α-GalA)in a 15-year-old male patient with typical Fabry disease,whose mother was without any clinical manifestations.Methods Clinical features and laboratory data were collected from the patient and his mother.Genomie DNA was extracted from peripheral blood of the patient.his mother,and a healthy control subject.Seven exons of the GLA gene were amplified by PCR.PCR products were purified.cloned into T vector,and then sequenced.The enzymatic activity of α-GalA Was measured by fluorimetrie substrate assay. Results DNA sequencing results showed that a missense mutation of 10036-10038delAAG in exon 7 WaS identified in the patient,resulting in the replacement of 374 lysine and 375 glyeine by arginine,which Was not previously reported.The patient Was a hemizygote with gene mutation,his mother WaS a heterozygote carrying gene mutation,and the healthy control without mutation.α-GalA enzymatic activity assay showed that the enzymatic activity of the patient with GLA gene mutation was only 50%of the healthy control subject,while the enzymatic activity of the patient's mother Was about 70%of the heahhy control SObject.Conclusiolls Detecting GLA gene mutation and α-GalA enzymatic activity in patients with Fabry disease who have been clinically diagnosed seelns to be helpful in finding other patients in the family and in further understanding the molecular pathogenesis of that disease.

Objective To review the experience of colon interposition in the treatment of benign esophageal stricture.Methods 58 patients who had undergone colon interposition for esophageal replacements were studied retrospectively,including 53 patients with corrosive burn esophageal strictures,3 traumatic esophageal strictures and 2 congenital esophageal strictures.The interposition colon for all patients went through substemum paths.Results There was no postoperative death in the duration of hospital stay.14 cases developed postoperative complication including 2 total colon necrosis,7 anastomotic leak,2 anastomotic stricture and 3 recurrent laryngeal nerve injury.52 patients were followed-up(ranged 1 to 16 years),40 cases were extremely satisfied(1 grade),9 very satisfied(2 grade),2 satisfied(3 grade)and 1 unsatisfied(4 grade).Conclusion Colon interposition is an ideal procedure for esophageal benign stricture.
