Objective To study the abnormal expression of P-AKT in follicular thyroid carcinoma and its relationship with angiogenesis. Methods MVD and expressions of P-AKT, VEGF in 40 specimens of FTC tissues were detected by immunohistochemical PV6000 method. Results The expression rate of P-AKT in FTC was higher than that of non-FTC tissues. The result was of statistical significance (P<0.001). There were correlations between the MVD of FTC tissue and the expression of P-AKT and VEGF (P<0.05). The MVD of P-AKT positive FTC tissue was higher than that of negative tissues (P<0.05). The MVD of VEGF positive FTC tissue was also higher than that of negative tissues(P<0.05). There were correlations between the expression of P-AKT and VEGF(P<0.05). Conclusion The hyperexpression of P-AKT played an important role in the secondary deposits and development of human follicular thyroid carcinoma. AKT/VEGF pathway may exist in FTC, and AKT is the key factor in the pathway which regulated the expression of VEGF.

Objective To investigate the systemic stress responses of laparoscopic cholecystectomy(LC). Methods Seventy patients with cholecystolithiasis were randomly divided into two groups: LC and open cholecystectomy(OC). Peripheral blood samples were obtained during the preoperative day and 1, 3, 5, 7 day after operation. Serum cytokines levels (TNF-α, IL-1β and IL-6) and C-reactive protein(CRP) were measured. Results Changes of TNF-α and IL-1β before or after surgery in both groups showed no significant difference(P>0.05). Serum concentrations of IL-6 and CRP after surgery in both groups were significantly higher than those before surgery(P<0.05); but there were no significant difference between the two groups(P>0.05). Conclusions The systemic stress responses of LC have no significant difference comparing with OC.

ObjectiveTo analyze the effects of three different display devices on the interpretation of imaging data in medieal imaging system.MethodsThe luminance-meter L100 and the test patterns provided by the American Association of Physicists in Medicine(AAPM)were used to assess the performance of three display devices(the spherical,flat panel and liquid crystal display devices).The corresponding luminance response was compared with the reference criteria provided by AAPM Task Group 18(AAPM TG18).DR chest photography was taken on CDRAD2.0 contrast-detail phantom using the following experimental parameters:100 mA,80 kVp,and the exposure times for 6,10,12,and 16 ms.After each exposure,the surface dose of phantom was recorded and the image quality factor(IQF)was calculated.Statistical analysis of IQF was performed using ANOVA. ResultsThe maximum luminance values in the spherical,flat panel and liquid crystal display devices were 170,59 and 231 cd/m2 and the luminance ratio was 257, 99 and 350 respectively.There was a significant difference in the IQF bewteen the liquid crystal display device and other two display devices.Conclusion The liquid crystal display device has the better image quality.

Objective To evaluate the influence of respiration on the radiation dose distribution within target volume in radiotherapy with film dosimetry. Methods Radiation of 50 MU was delivered by a square, round, ellipse, dumb bell, or female shaped filed to the films within a moving or motionless Respiration Motion Phantom respectively, the dose distributions for the two motion status were measured and compared. In order to further verify the impact of respiration, a plank phantom was used on different shifting value: 0, 0.5, 1.0, 1.5 and 2.0 cm, respectively. A square, round, or eUipse-shaped filed was used for irradiation and the distributions in different status were measured and compared with film dosimetry. Iso-dose line comparison, NAT(Normalized Agreement Tests) and γ comparison were used for the comparison of dose distributions. Fs can be an index to reflect the variability of the areas that surrounded by iso-dose lines. (FS90, FS50, FS25 delegates the ratio of the areas that surrounded by 90 %,50 %,25 % iso-dose hne in different situation respectively). Results (1) Compared with motionless situation, the FS90 in horizontal movement situation became small and the FS25 became large. As the displacement became larger, the FS90 became larger and the FS25 became smaller. FS in vertical movement situation, square and dumb bell fields changed while the others didn't have a change. (2)γ and NAT comparison: In the horizontal movement situation, compared with the static phantom, Pγ < 60 % and PNAT < 75 %. Under vertical movement situation, Pγ were less than 85 % for the square, round, dumb bell and female shaped fileds. In the plank phantom verification, Pγ and PNAT became smaller as the movement became larger. Conclusions The respiration can impact on the dose distribution within the target volume in radiotherapy, leading to a smaller area of higher dose level and an expanded area of lower dose level. The influence will become more significant with larger movement of the target.
