Objective To investigate the dosimetric properties of PTW 60019 synthetic diamond detector in small photon beams.Methods A PTW 60019 synthetic diamond detector was tested under 6 and 10 MV photon beams,respectively.Linearity with dose,dose rate dependence and off-axis ratio were measured and compared to those measured by an IBA SFD.Percentage depth doses were measured and compared to those measured by an IBA SFD and a PTW 31010 semiflex chamber.Total scatter factors were measured and compared to those measured by an IBA SFD and a PTW 31016 PinPoint chamber.Results The dose response of a PTW 60019 synthetic diamond detector showed a good linear behavior as a function of dose,with observed deviations below 0.2％ over a dose range from 100 to 1 000 MU.The dose rate response was almost independent,with deviations below 0.2％ in the dose rate range from 37 to 614 MU/min.For the fields of 20-100 mm in diameter,there were dose differences in percentage depth doses within 1％ as compared to an IBA SFD and a PTW 31010 semiflex chamber.For the 10 mm diameter field,the differences were up to 5.8％ in the build-up region.Off-axis ratios measurements showed a good agreement among the involved detectors (＜ 1％).The higher differences appeared in the penumbra region.A good agreement was also found in terms of total scatter factor measurements for the related detectors.Conclusions The observed dosimetric properties of the PTW 60019 synthetic diamond detector indicate that it is a suitable candidate for small photon beam dosimetry.

Objective To investigate the changes of protein kinase C(PKC)activity in peripheral blood T lymphocytes in children with chronic idiopathic thrombocytopenic purpura(CITP)and the relationship between PKC activity,T lymphocytes activation and thrombocytes decrease.Methods Collecting sterile peripheral blood from CITP children(n=30)and healthy children(n=30),T lymphocytes were isolated and purified by the T cell segregation enrichment column,the PKC activity was detected by non-radioactive assay.Soluble interleukin-2 receptor(sIL-2R),which was T cell activated marker,was determined by enzyme-linked immunoabsorbent assay(ELISA),platelet was counted by cell counting meter.Results Compared with healthy children,PKC activity was significantly enhanced in CITP children[(0.94?0.23)mmol/(min?L)vs(0.50?0.17)mmol/(min?L),t= 8.42 P

Objective To explore the influence of G4 cyberknife treatment of large hepatocellular car-cinoma on liver function,and to evaluate its treatment safety.Methods Sixty-three large liver cancer patients treated with routine G4 cyberknife treatment were retrospectively analyzed,and then statistical analysis of the difference in liver function before and after treatment was conducted.Results After G4 cyberknife treatment of 1 2 months,the levels of ALT,ALP,TBIL,PA were respectively 23.00 U /L,1 1 1 .00 U /L,1 3.70 μmol/L, (81 .87 ±1 3.94)%.Compared with the levels before treatment [28.00 U /L,32.00 U /L,1 1 .30 μmol/L, (86.07 ±1 4.07)%],there were no signi-ficant differences found (Z =-1 .677,P =0.094;Z =-0.504, P =0.61 4;Z =-1 .945,P =0.053;t =1 .271 ,P =0.21 3).The level of ambumin was (34.84 ±4.75)g/L at 1 2 months after treatment,which decreased and the difference compared with the level before treatment [(37.45 ±4.1 4)g/L]was significant (t =3.357,P =0.002).The Child-Pugh grade was 5.80 ±1 .1 7 respectively at the time points of 1 2 months after treatment,and no significant difference was found compared with the Child-Pugh grade before treatment (5.48 ±0.81 ,t =-1 .668,P =0.1 06).Conclusion G4 cyberknife treatment does not cause liver injury.It is safe and reliable in large liver cancer treatment.So,it is worth widely clinical popularizing.

Purpose :To study the effect of bFGF on the idiopathic oligoasthenospermia. Methods:bFGF wasused for 34 patients with idiopathic oligoasthenospermia in the male infertility. The immunohistochemical tech-nique, radioimmunoassay, electromicroscope technique and semen quality analysis were used to investigate thestructure and function of testile of patients. Results: bFGF could promote the proliferation of spermatogenouscells, improve arrangement of cells and ultrastructure of testile. All patients semen were improved. Sexual hor-mones (PRL, FSH, LH, T) in serum araised. The ability of reproduction of patients was increased consequent-ly. Conclusions:bFGF is an effective drug for patients with idiopathic oligoasthenospermia in the male infertility.
