Objective To evaluate the efficacy of Coopdech bronchial blocker combined with a strengthened single-lumen tube for airway management in patients undergoing upper mediastinal tumor resection. Methods Twenty-two ASA Ⅱ or Ⅲ patients, aged 24-66 yr, weighing 48-78 kg, scheduled for elective resection of upper mediastinal tumor, were randomly divided into 2 groups (n=11 each):double-lumen tube group(groupⅠ) and Coopdech bronchial blocker combined with a strengthened single-lumen tube group(group Ⅱ).One-lung ventilation was achieved with a double-lumen tube in groupⅠ. The Coopdech bronchial blocker combined with a strengthened single-lumen tube was used for airway management and the Coopdech bronchial blocker was used for lung isolation when one-lung ventilation was required in group Ⅱ. The fiberoptic bronchoscope was used to assist endotracheal tube positioning in both groups. The intubation time, positioning time, the number of patients required for tube displacement, the number of fiberoptic bronchoscopy, increase in airway peak pressure, degree of lung collapse, postoperative sore throat and hoarseness, and the number of patients needing ventilator-assisted ventilation were recorded. Results The intubation time was significantly shorter, the number of patients required for tube displacement was significantly smaller,and the rate of increase in airway peak pressure and incidences ofpostoperative sore throat and hoarseness were significantly lower in group Ⅱ than in group Ⅰ (P＜0.05 or0.01). Conclusion The efficacy of the Coopdech bronchial blocker combined with a strengthened single-lumen tube for airway management is better in patients undergoing upper mediastinal tumor resection than the double-lumen tube.

BACKGROUND: Islet transplantation is an effective method for the treatment of type 1 diabetes mellitus and parts of type 2 diabetes mellitus. However, its application is hindered by insufficient sources and immunologic rejection. Though transdifferentiation of pancreatic stem cells is at the starting step, it is thought to be the hopeful source for islet cell transplantation.OBJECTIVE: To look for a suitable cells-transplantation source for the treatment of diabetes mellitus. METHODS: The pancreatic ductal epithelial cells were separated from Kunming mice and cultured in DMEM/F12 medium supplemented with keratinocyte growth factor, hepatocyte growth factor and nicotinamide, etc. Samples were taken at different time points for light microscopy and electron microscope. The changes of CK-19 and PDX-1 were detected by immunocytochemistry at 1 and 16 days. The expressions of insulin and glucagon gene were detected by RT-PCR at 1 and 16 days. The physiologic function of these islet-like clusters was determined by dithizone staining and glucose stimulation at 21 days. RESULTS AND CONCLUSION: A large number of epitheliod cells were CK-19 immunoreactive positive and few of them were PDX-1 positive at 1 day after isolation, then CK-19 positive cells proliferated quickly and formed substantial plaques of epithelial cells in cobblestone pattern. At 16 days later, these cells begin to form islet-like clusters gradually, while most of them were PDX-1 immunoreactive positive. The analysis of mRNA by RT-PCR showed very low levels of insulin and glucagon mRNA in the starting materials but increase was found as the process of transdifferentiation. At 21 day differentiated islet-like clusters were stained red by dithizone. In those samples exposed to a stimulatory 15 mmol/L glucose, there was a 1.6-fold increase in insulin compared with to 5.6 mmol/L glucose (P < 0.05). Pancreatic ductal cells of adult Kunming mice could proliferate quickly and have the potency of transdifferentiation into islet-like clusters when cultured in vitro under appropriate conditions.

Objective To evaluate the prognosis value of the expression of galectin 3 in patients with acute ischemic stroke. Methods 165 Patients with acute ischemic stroke had been observated for 12 months and their occurrence of recurrent stroke e-vents were recorded.The concentration of galectin-3 was detected.Results 65 patients had recurrence stroke events with a rate of 39.39% within 12 months.It was also found that the serum concentration of galectin-3 in acute ischemic stroke recurrence patients were significantly higher than those of patients without recurrence,the difference was statistically significant(P <0.05).The rate of acute ischemic stroke recurrence in patients with high concentrations of galectin-3 was higher than that in patients with low concen-trations of galectin-3,the difference was statistically significant(P <0.05).Conclusion Galectin-3 is a good indicator to predict the prognosis of patients with acute ischemic stroke,and it could be used to evaluate the risk of recurrence in patients.

Objective:To investigate the renal injury of portal hypertensive rat after one hour of occlusion of portal vein and inferior vena cava.Methods:Healthy male Wistar rats were taken randomly as normal control、portal hypertensive control and trial group.The recoverable portal hypertensive model was induced firstly.Three weeks later ,15 model rats were taken randomly as portal hypertensive control group,others had another operation and were divided randomly into 0,6h,12h,24h,48h,72h,7d group according to different reperfusion time after 1 hour of occlusion of portal vein and inferior vena cava.At the corresponding time points after reperfusion,the examinations below were done:serum ALT,TBIL,BUN,Cr concentrations;mor-phological changes of liver and kidney,the ultrastructure of renal tissue.Results:Serum and Cr in trail group reached their peak value 12~24 hours after reperfusion,then decreased gradually,and returned to normal 72 hours after reperfusion.The main injury of kidney was located in proximal tubular epithelial cell ,it peaked at 12 hours and 24 hours after reperfusion,the sporadic karyopyknosis and karyorrhexis could be seen,but the basement membrane preserved well.48 hours later,the restoration could be seen.7 days later it restored obviously.Conclusion:There are obvious injury in tubular epithelial cell in the portal hypertensive rat after 1 hour of occlusion of portal vein and inferior vena cava.But the injury of kidney is reversible.

Objective To confirm a case of pachydermoperiostosis (primary hypertrophic osteoarthropathy) at the molecular level by gene sequencing.Methods Peripheral blood samples were obtained from a 26-year-old male patient with pachydermoperiostosis and his parents,and DNA was extracted from these blood samples.Polymerase chain reaction (PCR) was performed to amplify all the exons of HPGD and SLCO2A1 genes,and gene sequencing to identify gene mutations.According to sequencing results,the spatial structure of relevant proteins was predicted.Results Gene sequencing showed a homozygous frame-shifting mutation c.310_31 1delCT (p.L104AfsX3) in exon 3 of the HPGD gene in the patient.His mother was a heterozygous carrier of the mutation,but no mutation was identified in his father.The prediction of spacial structure of proteins revealed that the above gene mutation could shorten the length of the encoded peptide by about 60％.Conclusion Typical clinical manifestations and imaging findings are helpful for the primary diagnosis of pachydermoperiostosis,while mutation analysis of HPGD and SLCO2A1 genes is a main approach to its final diagnosis.

Objective To compare the effects of different medications of fentanyl during anesthesia induction on fentanyl-induced cough.Methods Four hundred and twenty ASA Ⅰ or Ⅱ patients aged 18-60 yr undergoing selective operations under general anesthesia,were randomly divided into 4 groups ( n =105 each):group Ⅰ (control group) received successive intravenous injection of midazolam 0.05 mg/kg,fentanyl 2 μg/kg,propofol 2 mg/kg,and rocuronium 1 mg/kg,group Ⅱ (pre-injection group) received successive intravenous injection of midazolam0.05 mg/kg,fentanyl 0.5 μg/kg,propofol 2 mg/kg,rocuronium 1 mg/kg,and fentanyl 1.5 μg/kg,group Ⅲ (dilution group) received successive intravenous injection of midazolam 0.05 mg/kg,fentanyl 2 μg/kg (20 μg/ml),propofol 2 mg/kg,and rocuronium 1 mg/kg,and group Ⅳ (last injection group) received successive intravenous injection of midazolam 0.05 mg/kg,propofol 2 mg/kg,rocuronium 1 mg/kg,and fentanyl 2 μg/kg.Fentanyl concentration was 50 μg/ml in each group except group Ⅲ.Endotracheal intubation was performed 2 min after anesthesia induction.The incidence and severity of fentanyl-induced cough before intubation were recorded and the incidence of propofol-induced pain was recorded.Invasive arterial blood pressure (ABP) and heart rate (HR) were observed before induction (T1 ),immediately after induction (T2 ),at time of coughing (T3 ),and at time of endotracheal intubation (T4).Results ABP and HR had no significant differences at T1,T2,T3,and T4between the four groups (P ＞ 0.05).The incidence of propofol-induced pain had no significant differences between the four groups (P ＞ 0.05).The incidences of cough was 7.6％ in group Ⅱ,9.5％ in group Ⅲ,and 1.9％ in group Ⅳ,which were significantly lower than 35.2％ in group Ⅰ ( P ＜ 0.01).The incidence of cough in group Ⅳ was significantly lower than that in groups [ and Ⅲ (P ＜ 0.05).In the four groups,ABP and HR were significantly higher at T3 than that at T1 and T2 ( P ＜ 0.01 ).Conclusion Different medications of fentanyl including last injection,pre-injection,and dilution of fentanyl can significantly reduce the incidence of fentanyl-induced cough during anesthesia induction,and injection has the best effect.

Objective The study was designed to compare the ultrasound-guided technique for the cannulation of subclavian vein with the traditional technique using anatomic landmarks.Methods One hundred and twenty ASA Ⅱ or Ⅲ patients undergoing cannulation of subclavian vein before gastrp-intestinal tumor resection were randomly divided into 2 groups (n=60 each) according to the technique used for cannulation:ultrasound-guided group (group US) and anatomic landmark group (group AL).The puncture time,successful puncture and complications were recorded.Resulls The success rate was 100% in group US;while the cannulation failed in one patient in group AL.The rate of successful puncture at 1st attempt was 100% in group US but ouly 90% in group AL.The cannulation time was significantly shorter in group US than in group AL.The incidence of accidental puncture of subclavian artery,hematoma and pneumothorax was significantly higher in group AL than in group US.Conclusion The ultrasound-guided catheterization of the subclavian vein is superior to the landmark technique.

[Summary] To discuss the clinical features and treatment of primary adrenal lymphoma( PAL) with empty sella(ES).The lymphoma of the patient was nonspecific,the levels of serum sodium, cortisol, adrenocorticotropic hormone, and gonadotropin were decreased.MRI confirmed ES, CT showed bilateral adrenal enlargement.CT-guided fine-needle aspiration biopsy of the adrenal gland revealed a cytological diagnosis of diffused large B cell lymphoma( DLBCL).The patient had received R-CHOP chemotherapy, which results in a complete functional recovery and the tumoral masses disappeared.PAL combined with ES was rarely reported, which is difficult to diagnose due to complex hormone levels.
