Objective To evaluate the clinic efficacy of sufentanil and remifentanil by target- controlled infusion (TCI) combined with propofol in patients undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).Methods Sixty patients,ASA Ⅰ ～ Ⅱ,undergoing elective EBUS-TBNA were randomly divided into group S ( sufentanil group),group R (remifentanil group) and group SR (sufentanil + remifentanil group),each group were twenty patients.The anesthesia of all groups is propofol intravenous anesthesia with 2％ lidocaine topical anesthesia,to controll BIS between 50 and 60 during surgery.Heart rate(HR),mean arterial pressure(MAP) pulse oxygen saturation( SpO2 ) and respiratory rate (RR) were recorded and compared 5mins after entering room(T0),30mins after the beginning of surgery(T1 ) and after surgery(T3).Arterial blood gas and the times of cough during surgery were also recorded and compared in all groups.The use of propofol and lidocaine,the wake-up time,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were also obtained.Results ( 1 ) RR decreased distinctly in group R and PaCO2 increased distinctly in group S and group R compared with that of group SR (P ＜0.05) during surgery.(2)The times of cough and the wake-up time lessened distinctly in group R and group SR compared with that of group S ( P ＜0.05 ).(3) The use of propofol and lidocaine,satisfaction with anesthesia and adverse reactions in 6 hrs after surgery were similar in all groups ( P ＞ 0.05 ).Conclusion Sufentanil compounded remifentanil by TCI combined with propofol is a safe and feasible anesthesia option for EBUS-TBNA,which provides better efficacy,high satisfaction and less side effects compared with using alone of sufentanil and remifentanil respectively.

Objective To explore the role and their relationship of Ki-67, VEGF and p27 expressed in adult patients with acute leukemia. Methods The expression of Ki-67, VEGF and p27 in bone marrow mononuclear cells (BMMNC) were analyzed by immunocytochemical staining, and their correlations of Ki-67, VEGF and p27 were statistically analyzed. Results The expression of Ki-67(42.48±25.78)% or VEGF (44.89±24.01)% on BMMNC from acute leukemia cells was significantly higher than that in the control (11.40±9.94)% or (16.90±12.54)% (P<0.01). But the expression of p27 (23.65±13.30)% was significantly lower than that in the control (50.23±22.68)% (P<0.01). The expressions of Ki-67 were positively correlated with and VEGF in patients with acute leukemia were positively correlated(r=-0.666, P<0.01), and the expressions of Ki-67 and p27 were negatively correlated with p27 in patients with acute leukemia (r=-0.316, P<0.05).Conclusion The evaluation of expression of Ki-67, VEGF and p27 on acute leukemic cells provides new insights to the pathogenesis is helpful in mechanism and is helpful in the diagnosis of acute leukemia.

Objective To explore the value of elective nodal prophylactic irradiation with intensity modulated radiotherapy(IMRT) for esophageal carcinoma.Screening patients who are suitable for elective nodal prophylactic irradiation (ENI),in order to improve locoregional control and overall survival.Methods The concurrent control study was conducted to esophageal cancer patients who were treated by definitive radiotherapy.A total of 148 patients finished treatment were identified.Seventy-four patients received ENI,while the other seventy-four patients received involved-field irradiation (IFI).Kaplan-Meier method was used for calculation of locoregional control rates and overall survival rates.The univariate and multivariate analysis of prognostic factors were also tested.Results The 1-,3-,and 5-year locoregional control rates of ENI group and IFI group were 72.5％,52.8％,50.6％ and 58.4％,35.8％,21.9％ (x2 =7.881,P ＜0.05),respectively.The 1,3,and 5 years survival rates of the ENI group and IFI group were 74.3％,44.2％,24.5％ and 68.9％,27.6％,15.9％ (x2 =1.903,P ＜ 0.05),respectively.In Cox multivariate analysis,clinical T stage,tumor location,different radiotherapy region were independent factors for the locoregional control of all patients,and clinical T,N stage,the length of esophageal barium meal and chemotherapy were independent factors for the overall survival of all patients.Conclusions Esophageal carcinoma patients treated with ENI could achieve better locoregional control than those treated with IFI.Esophageal carcinoma patients with early stage or middle thoracic lesion could benefit from ENI for local control and overall survival.

Objective:To examine the expression of odontoblast related proteins in dental pulp stem cells(DPSCs)induced by BMP-7.Methods:DPSCs were cultured in the common culture medium or medium supplemented with 1 00 ng/ml BMP-7.Electron microscope,CCK8 and immunohistochemical staining were carried out to estimate the cell morphology and differentiation.Results:In-duced by BMP-7,the morphology of DPSCs was not changed,the proliferation of DPSCs was slower than that of the cells without BMP-7 treatment.DPSCs were negative for the expression of DSPP,DMP-7 and ALP.However,DPSCs were found strongly positive for DSPP,DMP-7 and ALP after the induction of BMP-7.Conclusion:BMP-7 induction may promote the differentiation of DPSCs.

Objective To compare the efficacy of elective nodal prophylactic irradiation ( ENI) and involved?field irradiation ( IFI) in radical radiotherapy for early?stage esophageal cancer and to determine the appropriate irradiation range for early?stage esophageal cancer. Methods The clinical data of 121 patients with early?stage esophageal cancer receiving radical radiotherapy in our hospital from January 2006 to December 2011 were collected and respectively analyzed. Sixty?one patients received ENI, and the other 60 patients received IFI. The Kaplan?Meier method was used to calculate local control ( LC) and overall survival ( OS) rates;the log?rank test was used for survival difference analysis and univariate prognostic analysis;the Cox regression model was used for multivariate prognostic analysis. Results The 1?, 3?, and 5?year LC rates in ENI group and IFI group were 81. 1%, 60. 1%, and 57. 5% vs. 64. 5%, 43. 9%, and 27. 2%, respectively ( P=0. 003 ) . The 1?, 3?, and 5?year OS rates in ENI group and IFI group were 86. 9%, 56. 8%, and 34. 8% vs. 86. 7%, 34. 3%, and 19. 1%, respectively ( P=0. 019) . The 1?, 3?,and 5?year overall failure rates in ENI group and IFI group were 22. 3%, 53. 8%, and 63. 2% vs. 43. 3%, 65. 8%, and 78. 8%, respectively ( P=0. 023) . Multivariate analysis showed that irradiation range was the influencing factor for LC and OS. Conclusions As for the radical radiotherapy for early?stage esophageal cancer, ENI can significantly increase LC and reduce locoregional failure, and therefore improve long?term OS.

Objective To compare the failure pattern between esophageal cancer patients receiving definitive elective nodal irradiation (ENI) and involved-field irradiation (IFI) and to investigate the reasons and influential factors for locoregional recurrence and metastasis.Methods A retrospective analysis was performed on the clinical data of 245 patients with esophageal cancer who received definitive radiotherapy in our hospital from January 2006 to December 2012.One hundred and twenty-six patients received ENI,and the other 119 patients received IFI.Failure patterns were analyzed after treatment.Locoregional failures included local esophageal lesion uncontrol or recurrence and regional lymph node recurrence or metastasis.Distant metastases included distant organ metastasis and distant lymph node metastasis.Comparison of failure pattern between the two therapies was made by chi-square test.Results One hundred and sixty-three patients had failure after treatment.Locoregional failure was observed in 92 patients,distant metastasis in 36 patients,and locoregional failure plus distant metastasis in 35 patients.The 1-,3-,and 5-year overall failure rate for the ENI group were 35.4％,62.5％,and 69.0％,respectively,versus 46.5％,71.5％,and 81.5％ for the IFI group (P =0.036).The 1-,3-,and 5-year locoregional failure rates for the ENI group were 29.9％,48.4％,and 50.0％,respectively,versus 39.6％,62.1％,and 71.4％ for the IFI group (P =0.003).Conclusions For esophageal cancer patients receiving definitive radiotherapy,ENI can significantly reduce locoregional failures and increase locoregional control,thus improving the long-term survival.
