Objective: To investigate the effect of antisense oligodeoxynucleotide (ASODN) of Livin mRNA on the proliferation and apoptosis of human lung adenocarcinorna A549 cells. Methods: Livin ASODN was transfected into A549 cells mediated by cationic liposome. The proliferation rates of A549 cells were assessed by MTT method. The transcription of Livin mRNA was detected by RT-PCR. The Livin protein expression was determined by immunohistochemistry and confocal laser scanning microscopy before and after transfection. The apoptotic ratios of A549 cells were examined by acridine orange/ethidium bromide(AO/EB) fluorescent staining. Results: It was observed that A549 cells expressed both Livin α and Livin β simultaneously, and the distribution of Livin protein could be observed in both cytoplasm and nuclei. The proliferation of A549 cells was inhibited significantly by Livin ASODN in a dose-dependent manner (P<0.01). After transfection of Lip-ASODN at a final concentration of 400 nmol/L, the expressions of Uvin were inhibited at mRNA and protein levels and the apoptotic ratio reached (31.25 ± 5.75)%. The difference was significant compared with control group [ (3.23% ± 1.98)%, P<0.01]. Conclusion: Livin ASODN significantly down-regulates the expression of Livin mRNA and effectively inhibites the proliferation and induces the apoptosis of A549 cells. Therefore Livin gene may become a new target for gene therapy for lung cancer.

Objective To evaluate the accuracy of bispectral index(BIS)and entropy index in monitoring the depth of anesthesia in patients during target-controlled infusion(TCI)of propofol on induction of anesthesia.Methods Fifty ASA grade Ⅰ-Ⅱ of chronic sinusitis patients who performed the surgery of nasal sinus patency were enrolled in this study.After into operation room(T0),anesthesia was induced with TCI of propofol,and it was added 0.3 μ g/ml after 30 seconds once the plasma drug level was 2.1 μ g/ml(T1)until loss of consciousness(T2),and added 0.5 μg/ml(T3).When tracheal intubation,the patients was injected 0.6 mg/kg rocuronium in their intravenous at the prospective plasma drug level(T4).Each case was monitored with BIS,state entropy index(SE)and response entropy index(RE).The data at following time were recorded:T0-T4,tracheal intubation(T5),1 minute and 3 minutes after tracheal intubation(T6,T7),skin incision(T8).Results The value of BIS,SE and RE were significantly decreased compared with T0 (P ＜0.05).Mean arterial pressure(MAP)and heart rate were in normal range.The value of RE was significantly higher than SE at all the time points(93 ± 9 vs.87 ± 5,88 ± 12 vs.82 ± 12,73 ± 25 vs.72 ± 21,57±21 vs.56±22,46± 16vs.43 ± 17,39± 14 vs.37± 12,36± 14vs.34± 11,35 ± 11 vs.32±9,39±15 vs.36 ± 12)(P ＜ 0.05),but there was no significantly difference between BIS and SE at all the time points(P ＞ 0.05).The value of BIS had significantly positive correlation with SE and RE(r =0.887,0.901 ;P ＜ 0.01).Conclusions During deep hypnosis,BIS,SE and RE all can provide information about the level of consciousness during TCI of propofol on induction of anesthesia.RE is more preponderant as a monitor than BIS and SE.

Objective To investigate the predictive value of symmetrical ambulatory arterial stiffness index (S-AASI) in detecting early renal impairment of patients with essential hypertension.Methods Totally 245 consecutive out-patients were confirmed with essential hypertension,and were divided into group A (56 cases),group B (64 cases),group C (72 cases),and group D (53 cases) according to the quartile of S-AASI.The combination testing of serum cystatin C,serum β2-microglobulin as well as urine microalbumin to creatinine ratio were implemented as laboratory diagnosis index of renal impairment in early stage and 109 essential hypertension patients were diagnosed with early renal impairment.The parameters were compared among 4 groups.Pearson correlation analysis and partial correlation analysis were performed to confirm the relationship between the markers of early renal impairment and S-AASI.The predictive value of S-AASI to detect early renal injury was evaluated by analyzing Receiver Operating Characteristic (ROC) curve.Results With the rising of S-AASI,age as well as 24 hours mean systolic blood pressure (24 h SBP),serum cystatin C,serum β2-microglobulin,urine microalbumin to creatinine ratio and the incidence rate of early renal injury went notably higher while estimated glomerular filtration rate (eGFR) decreased significantly.After controlling for age,correlation test showed S-AASI was positively correlated with24hSBP,serum cystatin C,serumβ2-microglobulin,urine microalbumin to creatinine ratio(r =0.392,0.627,0.514 and 0.643 respectively,P ＜ 0.05) and negatively correlated with eGFR(r =-0.312,P ＜ 0.05).The 24 hours mean diastolic blood pressure (24 h DBP) was uncorrelated with S-AASI.Area under ROC curve of S-AASI for diagnosis of hypertensive renal impairment was 0.885.The critical value of S-AA-SI was 0.17,the sensitivity,specificity,positive predictive value,and negative predictive value were 92.7％,65.2％,68.5％,and 91.7％,respectively.Conclusions When S-AASI was detected above 0.17,patients with hypertension had a higher risk of renal impairment.Higher S-AASI was correlated with worse early renal impairment laboratory indexes.The predictive accuracy of S-AASI for early hypertensive renal impairment was medium.

Purpose:To study the effect of insulin-like growth factor 1 receptor ?-strain(IGF1R-?) interrupted by a special antibody (IGFⅠR-?Mab)on lung adenoma cell line SPC-A-1.Methods:IGFⅠR-?Mab was extracted by hybrid technology. SPC-A-1 cells were separated into 2 groups,the IGFⅠR-?Mab and the blank control. The IGFⅠR-?Mab cells were interfered by different densities of IGFⅠR-?Mab, including 20,40,60,80,100,120,140,160,180 and 200 ng/ml. The MTT curve line, morphology, ultrastructure and cell cycles were observed at 0,24,48,72 hours after the intervention respectively. Results:Compared with the control, apoptosis in IGFⅠR-?Mab group was significant(P= 0.009)and proliferation rate was decreased obviously within 160 ng/ml. However, the proliferation rate was no significant when the special antibody density was more than 200 ng/ml.Conclusions:The affinity of IGFⅠR-?Mab at IGF1R ?-strain is high. The interruption of IGF1R ?-strain by IGFⅠR-?Mab shows the obvious biological effects in vitro ,with inclusion of promoting apoptosis and suppressing proliferation, which indicate the interruption targeting IGF1R ?-strain is prospective for non-small-cell lung carcinoma.
