Objective:To analyze the reasons of complicated arrhythmia after resection of lung. Methods:The relation of arrhythmia with age, operation mode,preoperative lung function and postoperative blood gas of 562 cases of lung resection were analyzed. Results:There were 104 of 562 cases (18.5%) complicated with arrhythmia postoperatively. 38.77% of them were older than 70 years. 27.72% had operation of pneumonectomy.The parameters of FEV 1,MVV,FVC lower than 50% were 67.24%,46.53% and 67.93% respectively.Postoperative blood gas analysis of the 23 cases showed that Po 2 was lower than 60 mmHg,Pco 2 was higher than 45 mmHg,So 2 was lower than 96%.21 of them developed postoperative arrhythmia.After tracheotomy and immediately correcting anoxia,all the 21 patients recovered from arrhythmia within 3 days.4 patients died in this group(3.84%).Conclusion:Pneumonectomy,in patients older than 70,results in the parameters of FEV 1,MVV and FVC lower than 50%.Significant anoxia is the cause of arrhythmia.

Objective:To discuss the method of Video Assisted Thoracoscopy(VATS) in diagnosis and treatment of small peripheral lung neoplasm.Methods:A wedge-shaped excision with VATS had been performed on 20 patients with small peripheral lung neoplasm.The sample had been sent to pathology during surgery.Lobectomy was done with the malignant tumor.Results:14 cases(70%) were malignant in stage IA ,6 cases were benign.The mean follow-up time postoperatively was 24 months(12～36months),there was no relapse case.Conclusion:For those patients,the diameter of neoplasm is smaller than 15mm,and antibiotic treatment is ineffective for 2～3 weeks,VATS can be available for diagnosis and treatment.

Objective To establish a Chromatin immunoprecipitation assay to analyze transcriptional regulation of gene expression in hepatocytes. Methods The PEPCK gene was used as a target gene, HPRT, MBP and IgG were used as internal reference, the chromatin immunoprecipitation and PCR were performed with antibody specific for CREB to verify bindings of transcription factor CREB to the PEPCK promoter under various metabolic conditions. Results Transcription factor CREB occupies its target sites in the PEPCK promoter and this binding is increased by 4-fold during fasting in the anti-CREB antibody immunoprecipitated DNA fragments. Conclusion The results confirm that CREB binds to the PEPCK promoter and is involved in transcriptional regulation of PEPCK gene in hepatocytes.

OBJECTIVE: To observe the effects of long-term administration of pioglitazone at different doses on the expression of glucose transporter-4(GLUT-4) of cardiac muscle tissue in rats and to discuss the possible mechanisms.METHODS: A total of 40 Wistar rats were enrolled,of which,10 were randomly assigned to normal control group(NC),and the other 30 were injected intraperitoneally with streptozotocin to establish diabetes mellitus(DM) rat model.After successful modeling,the rats were assigned to DM model group(DM,normal saline),high and low dose pioglitazone group(HP,LP;0.75,0.25 mg?kg-1?d-1).The NC groups received normal saline for 12 weeks.Blood glucose(BG) level before grouping(baseline level) and prior to death was determined by tail-cutting method.GLUT-4 level in cardiac muscle tissue and both protein and mRNA expression of AMPK? were determined by RT-PCR and western blot,respectively.RESULTS: As compared with NC group,the BG level in DM group was significantly increased but the expression of GLUT-4 and AMPK? decreased significantly(P
