Objective To determine the effects of different doses of cisatracurium on motor e-voked potential of neurosurgery operation.Methods Sixty patients,36 males and 24 females,aged 18 to 65 years,ASA physical status Ⅰ or Ⅱ,scheduled for spinal surgery with motor evoked potential monitoring,were included and randomly assigned to three groups.A single dose of cisatra-curium besilate for injection was given by intravenous injection in 5 s after the induction of general an-esthesia,respectively 0.1 mg/kg (group A),0.1 5 mg/kg (group B)and 0.2 mg/kg (group C).Cas-cade Elite 32 channel monitor was used to monitor MEPs,the electrode was stimulated for once two minutes after given the muscle relaxant,and the leading time of the wave of MEPs was recorded. Cooper’s score was used to evaluate the intubation conditions.Results The appearance time of the wave of motor evoked potentials was significantly longer in group C [(39.60±1.79)min]than that in groups A [(20.10 ± 1.89 )min]and B [(20.50 ± 1.93 )min](P < 0.05 ).The intubation conditions was significantly better in group B (100%)and C (100%)than that in group A (65%)(P<0.05).Conclusion The shortest time to elicit waveform of MEPs using the dose of cisatracurium is 0.1 5 mg/kg at induction of general anesthesia,which is better for tracheal intubation.The dose 0.1 5 mg/kg of cisatracurim is recommended as the initial dose on neurosurgery operation with motor e-voked potential monitoring.

OBJECTIVETo explore the differences in sensitivity to rapamycin of five esophageal squamous cell carcinoma cell lines with different differentiation and the changes of sensitivity of the cells after siRNA-interfered expression of p70S6K.

METHODSEffects of rapamycin on proliferation of ESCC cell lines with different differentiation, EC9706, TE-1, Eca109, KYSE790 and KYSE450 cells, were investigated using cell counting kit 8 (CCK-8) assay, and according to the above results, the EC9706 cells non-sensitive to rapamycin were chosen to be transfected with p70S6K-siRNA. The changes in sensitivity of cells to rapamycin were measured in vitro and in vivo using CCK-8 kit, flow cytometry and tumor formation in nude mice.

RESULTSCCK-8 results showed that all the five cell line cells were sensitive to low concentration of rapamycin (<100 nmol/L), but TE-1 and EC9706 cells, which were with poor differentiation, showed resistance to high concentration of rapamycin. After EC9706 cells were treated with 50, 100, 200, 500 and 1 000 nmol/L rapamycin and p70S6K-siRNA, the proliferation rates of EC9706 cells were (48.67 ± 1.68)%, (15.45 ± 1.54)%, (14.00 ± 0.91)%, (10.97 ± 0.72)% and (2.70 ± 0.32)%, respectively, and were significantly lower than that of cells treated with 50, 100, 200, 500 and 1 000 nmol/L rapamycin and control siRNA [(74.53 ± 1.71)%, (68.27 ± 1.35)%, (71.74 ± 2.44)%, (76.23 ± 1.02)% and (80.21 ± 2.77)%] (P<0.05 for all). The results of flow cytometry showed that the ratios of cells in G1 phase of the p70S6K-siRNA, rapamycin and p70S6K-siRNA+ rapamycin groups were (53.82 ± 1.78)%, (57.87 ± 4.01)% and (73.73 ± 3.68)%, respectively, significantly higher than that in the control group (46.09 ± 2.31)% (P<0.05 for all). The results of tumor formation test in vivo showed that the inhibitory effect of rapamycin on tumor growth was stronger after the cells were transfected with p70S6K-siRNA, and the inhibition rate was 96.5%.

CONCLUSIONESCC cells with different differentiation have different sensitivity to rapamycin, and p70S6K-siRNA can improve the sensitivity of cells to rapamycin in vitro and in vivo.

Objective To investigate the effect of cyclosporine blood level at first year after kidney transplantation on patients with a survival time over 10 years. Methods 380 patients with functional allograft, a survival time over 10 years and long-term administration of cyclosporine A (CsA) were studied, and received CsA-based treatments. According to the blood CsA level at the first year after kidney transplantation, patients were divided into five groups: group 1, blood CsA level was above 0. 208 μmol/L (1 μmol/L = 1201.9 μg/L), group 2, blood CsA level between 0. 166-0. 208μmol/L; group 3, blood CsA blood level between 0. 125-0. 166 μmol/L; group 4, blood CsA blood level between 0. 083-0. 125 μmol/L; group 5, blood CsA level less than 0. 083 μmol/L. Systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine(SCr), uric acid (UA), cholesterol (CH), triglyceride (TG), alanine aminotransferase (ALT), direct bilirubin (DBil) and total bilibubin (TBil), albumin (Alb), hemoglobin (Hb), count of white blood cells and positive rate of proteinuria in 5 groups at the 1st, 5th and 10th year after kidney transplantation were analyzed. Results At the 5th year SBP in groups 1 and 2 was higher than in groups 3, 4 and 5. UA level in group 5 was lower than other groups, and Alb level in group 5 was higher than other 4 groups. Proteinuria positive rate in groups 4 and group was lower than other groups. At the 10th year after kidney transplantation,indexes among 5 groups had no statistically significant difference, except for SBP, DBP, DBil and CH in some groups. There was also no significant difference in SCr level among 5 groups at the 5th or 10th year after transplantation. Conclusion Blood CsA levels at the first year after kidney transplantation has no significant effect on long-term allograft function. But higher level of CsA (＞0. 166μmol/L) at the first year maybe predict high rate of hypertension, high blood UA and proteinuria at the 5th and 10th year after transplantation.
