A Pilot Study of Prognostic Value of Metastatic Lymph Node Count and Size in Patients with Different Stages of Gastric Carcinoma.

Background: The correlation between the preoperative lymph node count (LNC) on multidetector computed tomography (MDCT) and the prognosis of gastric carcinoma (GC) remains to be defined. This research aims to evaluate the prognostic value of LNC on MDCT in GC patients based on tumor-node-metastasis (TNM) staging, using different size criteria for counting.

Methods: The clinical data of 126 patients with gastric adenocarcinoma undergoing gastrectomy were retrospectively analyzed.

[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.

[Application of microcolumn gel immunoassay in screening the platelet antibody].

The purpose of this study was to explore the clinical value of the platelet antibody screening and typing in platelets transfusion by using microcolumn gel immunoassay (MGIA). The platelets antigen-antibody reactions including the antibody screen and blood crossmatch were detected by MGIA. The results indicated that the detection of platelet antibody showed positive in 30 cases of aplastic anemia (AA), 11 cases of myelodysplastic syndrome (MDS), 24 out of 25 cases of leukemia and 1 out of cases of other diseases, while detection of platelet antibody showed negative in 20 normal volunteer donors.
