Objective: To establish a 14-color flow cytometry protocol for the examination of leukocyte subsets in human peripheral blood.
Methods: We used cell membrane surface antibodies CD45, CD3, CD4, CD8, CD19, CD56, CD16, CD14, CD25, CD127, HLA-DR, CD123, CD11c and nucleus staining dye DAPI to establish a 14-color flow cytometry assay to determine the major cell subsets in human peripheral blood. We collected peripheral blood specimens from healthy volunteers to test for antibody titers and optimal photomultiplier tube (PMT) voltage, and to conduct single-color staining and fluorescence minus one control staining.
Purpose: Ablative hypofractionated radiation therapy (AHFRT) presents a therapeutic advantage compared with conventional fractionated radiation therapy (CFRT) for primary and oligometastatic cancers. However, the underlying mechanisms remain largely unknown. In the present study, we compared the immune alterations in response to AHFRT versus CFRT and examined the significance of immune regulations contributing to the efficacy of AHFRT.

Objectives: To explore the expression of platelets microparticles (PMPs) in peripheral blood (PB) and synovial fluid (SF) of rheumatoid arthritis (RA) patients and its correlation with clinical inflammatory parameters.
Methods: The levels of PMPs in PB were detected by flow cytometry in 26 active RA patients and 15 healthy control (HC). SF was collected from 16 patients.
Genetic modification of whole-cell cancer vaccines to augment their efficacies has a history of over two and a half decades. Various genes and gene combinations, targeting different aspects of immune responses have been tested in pursuit of potent adjuvant effects. Here we show that co-expression of two cytokine members of the common cytokine receptor γ-chain family, IL-21 and IL-7, in whole-cell cancer vaccines boosts antitumor immunity in a CD4(+) and CD8(+) T cell-dependent fashion.

As demonstrated by flow cytometry, the immunophenotypes are able to determine the stages of B cell development. Multicolor flow cytometry (MFC) is more accurate at identifying cell populations.

Methods: We used 5 antibodies (CD3, CD4, CD8, CD95, CD69), phospholipids binding proteins Annexin V, TCR Vβ Repertoire Kit and nucleus dye DAPI to establish a 9-color flow cytometry assay. Peripheral blood samples were taken from eight healthy people for test of antibodies and determination of optimal PMT and staining method (single-stained vs stained with all but one antibody).
Da Cheng Qi decoction (DCQD) is composed of Dahuang, Houpu, Zhishi and Mangxiao. It is a formula created under the theory of Chinese medicine to purge the 'evil heat' in the gastrointestitinal tract, which arises from the ileus and acute pancreatitis. The present study was conducted to evaluate the herb-drug interaction between DCQD and ranitidine, which are often co-administered in clinical practice.

Methods: Eighty-nine cases of female urethral syndrome were randomly divided into an electroacupuncture group and a hand-acupuncture group. The scores were evaluated with I-PSS of International Urine-Controlled Association and life quality before and after treatment, and their therapeutic effects were compared.
