BACKGROUND: Tumor-infiltrating T cells have a positive influence on the clinical course of B cell non-Hodgkin's lymphoma (NHL). T cells in the peripheral blood of patients with B cell NHL, however, have so far rarely been examined. METHODS: Using flow cytometry we examined lymphocyte subpopulations and numbers of na?ve/memory T cell subtypes among peripheral T cells of patients with B cell NHL (N=22), patients with metastasized solid tumors (N=27), and healthy controls (N=20). In addition, we analyzed the intracellular content of effector molecules granzyme B and perforin and expression of the T cell receptor zeta chain. RESULTS: We observed increased percentages of potentially highly cytotoxic CD8+CD56+ T cells in the peripheral blood of patients with NHL. Both, patients with NHL and patients with solid tumors showed a much higher expression of the chemokine receptors CCR4 and CCR5 on their T cells than healthy controls, suggesting a polarization of their T cells following stimulation with antigen and/or cytokines in vivo. Furthermore, patients with B cell NHL and patients with solid tumors had far lower percentages of na?ve CD45RA+CCR7+ T cells than healthy controls and, in the case of CD4+ T cells, patients with solid tumors. In contrast, patients with B cell NHL showed markedly increased levels of memory effector CD45RA-CCR7- CD4(+) T cells when compared to healthy controls and patients with metastasized solid tumors. Patients with NHL also showed elevated levels granzyme B within CD8(+) T cells, indicating that the increase in memory effector cells was of functional relevance. CONCLUSIONS: These findings indicate a marked shift in the composition of peripheral T cells of patients with B cell NHL from na?ve to memory effector-type cells. 相似文献

Our experience with pectoralis major flap for management of sternal dehiscence: A review of 25 cases

Objective:
To report our experience of the pectoralis major flap as the treatment modality for post coronary artery bypass sternal wound dehiscence.Materials and Methods:
A retrospective study of 25 open heart surgery cases, performed between January 2006 and December 2010 at Deenanath Mangeshkar Hospital, Pune, was carried out. Unilateral or bilateral pectoralis major muscle flap by the double breasting technique using rectus extension was used in the management of these patients. The outcome was assessed on the basis of efficacy of flap surgery in achieving wound healing and post-surgery shoulder joint movements to evaluate donor site morbidity. The follow-up ranged from 5 months to 3.5 years.Results:
Twenty-three (92%) patients were discharged with complete wound closure. One patient (4%) had wound dehiscence after flap surgery. One patient (4%) died in the hospital in the immediate postoperative period due to mediastinitis. No recurrent sternum infection has occurred till date in 24 patients (96%). For one patient (4%) who had wound dehiscence, daily dressing was done and wound healing was achieved with secondary intension. At follow-up, shoulder joint movements were normal in all the patients.Conclusions:
The double breasting technique of the pectoralis major muscle flaps with rectus sheath extension is efficient in covering the entire length of the defect and can reduce the morbidity, without affecting the function of the shoulder joint.KEY WORDS: Bilateral pectoralis major flaps, left internal mammary artery and right internal mammary artery, sternal dehiscence 相似文献54.
