[Diagnostic Significance of BAT in Anaphylaxis to Non-ionic Contrast Media].

Objective: To investigate the diagnostic significance of basophil activation test (BAT) in anaphylaxis to non-ionic contrast media through testing the content of CD63, mast cell-carboxypeptidase A3 (MC-CPA3), and terminal complement complex SC5b-9 of the individuals by testing their levels in the normal immune group and the anaphylaxis groups to β-lactam drugs and non -ionic contrast media.

Methods: The CD63 expression of basophilic granulocyte in blood was detected by flow cytometry. The levels of MC-CPA3 in blood serum and SC5b-9 in blood plasma were detected by ELISA.

[Phase separation and transport behaviors in La(0.7 - x)Dy(x)Sr0.3MnO3 system].

The influence of Dy doping (0.00 < or = x < or = 0.30) on magnetic and electric properties of La0.

Therapeutic effect of three-dimensional conformal radiotherapy on locally advanced pancreatic carcinoma.

Objective: To evaluate the effects of the two conformal radiotherapy modalities in the treatment of locally advanced pancreatic carcinoma.

Methods: From October, 1998 to June, 2001, 67 patients with locally advanced pancreatic carcinoma received conformal radiotherapy (CRT). Vacuum cushions were applied to immobilize the patients before contrast CT scans, the treatment plans were simulated by three-dimensional treatment planning system.

Therapeutic effect of high-dose three-dimensional conformal radiotherapy and conventional radiotherapy for non-small-cell lung cancer.

Objective: To improve the therapeutic effect of radiotherapy without increasing the risk of radiation injury in patients with non-small cell lung cancer (NSCLC).

Methods: From August 1998 to August 1999, 135 patients with NSCLC received radiotherapy, of whom 62 were treated with high-dose three-dimensional conformal radiotherapy (3D-CRT) at the total dose of 48 to 64 Gy in 6 to 8 fractions implemented in a course of 2 to 3 weeks, 6 to 8 Gy for each fraction. The other 73 patients underwent conventional radiotherapy (CR) at the total dose of 60 to 70 Gy in 30 to 35 fractions completed in 6 to 7 weeks.
