Objective To evaluate the effectiveness of midazolam and morphine combined with TCI of propofol for endobronchial ultrasound-guided transbronchial needle aspiration ( EBUS-TBNA ). Methods Forty ASA Ⅰ or Ⅱ patients undergoing elective EBUS-TBNA were randomly divided into 2 groups according to the plasma concentration (Cp) of TCI of propofol (n=20 each): group Ⅰ Cp = 3 μg/ml (group P1) and group Ⅱ Cp = 4 μg/ml (group P2 ). Midazolam 0.03 mg/kg and morphine 0.05 mg/kg were administered iv followed by topical anesthesia of laryngopharynx with 4% hdocaine. TCI of propofol was started at 5 min before surgery. The patients kept spontaneous breathing during operation. MAP, HR and SpO2 were continuously monitored and recorded before anesthesia (baseline) and at 30 min after beginning of surgery and emergence from anesthesia. Arterial blood gas analysis was performed at 30 min after beginning of surgery and PETCO2 was measured at the end of surgery. The amount of 4% lidocaine used for topical anesthesia, the adverse reactions and the level of patient's satisfaction were recorded. Results PaO2 and pH value were significantly lower while PaCO2 and PET CO2 higher in group P2 than in group P1. There was no significant difference in the emergence time, the amount of 4% lidocaine used,the adverse reactions and the level of patient's satisfaction between the 2 groups. Conclusion TCI of propofol at Cp of 3 μg/ml can provide satisfactory anesthesia for EBUS-TBNA with less respiratory depression and more rapid emergence than that at Cp of 4 μg/ml.

OBJECTIVETo investigate the methylation status of zonula occludens-1 (ZO-1) gene promoter and its clinical significance in children with stage IV non-Hodgkin lymphoma (NHL) and to provide a basis for further etiological study and early diagnosis of this disease.
METHODSFifty-five children with a confirmed diagnosis of stage IV NHL (40 cases of T-NHL and 15 cases of B-NHL) were selected as the case group, and 20 children with diseases other than hematologic malignancies were selected as the control group. Bone marrow samples were collected from these subjects. Methylation-specific PCR (MS-PCR) was applied to evaluate the methylation status of ZO-1 gene promoter, and the integrated optical density (IOD) was determined. RT-PCR was used to measure the mRNA expression of ZO-1.
RESULTSMS-PCR showed that the methylated bands of ZO-1 gene promoter were found in 39 (70.9%) of 55 patients in the case group before treatment, while no ZO-1 gene promoter methylation was detected in the control group. With close tracking of 47 cases in the study group, consisting of 32 cases of T-NHL and 15 cases of B-NHL, the rates of ZO-1 gene promoter methylation prior to treatment were 72% and 67%, respectively, (P>0.572). The cases of T-NHL and B-NHL showed no significant changes in methylation rate in the early and middle phases of chemotherapy (P>0.05), but they showed significant changes in methylation rate in the late phase of chemotherapy (P<0.05). RT-PCR showed that the NHL cases carrying methylated ZO-1 gene had no mRNA expression of ZO-1, while all children in the control group had mRNA expression of ZO-1. There was no linear relationship between the total number of peripheral blood leukocytes and ZO-1 gene IOD (r=0.093, P=0.575); a positive correlation was found between the number of malignant cells in bone marrow and ZO-1 gene IOD (r=0.669, P<0.001).
CONCLUSIONSZO-1 gene shows a hypermethylation status in children with NHL, and the methylation level is positively correlated with the number of malignant cells in bone marrow. ZO-1 may be used as a novel molecular marker in early diagnosis, outcome assessment, prognostic evaluation, and detection of minimal residual disease.

Objective To prepare lipid-coated ultrasound microbubbles containing 10-HCPT(HLM) and explore the antitumor effects on mice xenografed H22 solid tumor using the technique of ultrasound-mediated HLM destruction. Methods Sixty-four tumor-bearing mice were radomly divided into A and B groups. Each group was divided into four groups again and administered respectively by tail vein with HI.M, non-drug-loaded microbubbles,10-HCPT and saline once a day. Ultrasound irradiation was applied on the tumor sites immediately after injection. After 7 days of consecutive treatment, all mice in group A were sacrificed and the tumors were harvested to measure weights. The tumor inhibition rate was calculated by weights. The tumor microvessel density (MVD) was detected by immunohistochemical staining. The tumor growth curve was depicted according to volumes. The survival time of mice in group B was recorded. Results The tumor inhibition rate was the highest in HLM group while this group's MVD was the lowest. Survival time in HLM group and 10-HCPT group were obviously longer compared with the control group,while no statistic difference was observed between the two groups. There was no statistic difference between the group of non-drug-loaded microbubbles and the control group. Conclusions Ultrasound irradiation mediates HLM destruction so that the drug is released from the vihicles at the same time, which can significantly enhance the tumor inhibition effect of 10-HCPT on the H22 tumor. This technique is expected to be adopted as a novel tool for liver cancer chemotherapy.
