Objective:To determine the distribution of T-lymphocyte subpopulations in peripheral blood and its relationship with disease-free survival (DFS) of patients with different molecular subtypes of invasive breast cancer (IBC). Methods:Data and plasma samples of 372 female patients with IBC treated at Tianjin Medical University Cancer Hospital and Institute between January 2008 and August 2009 were obtained. CD4+/CD8+ratio and the amount of regulatory T cells (Treg cells) and natural killer cells (NK cells) were measured through flow cytometry. Results:A total of 133 (35.8%), 124 (33.3%), 48 (12.9%), and 67 cases (18.0%) presented luminal type A, luminal type B, HER-2 over-expression, and triple-negative type breast cancer (TNBC), respectively. In TNBC, a longer DFS was observed when the peripheral CD4+/CD8+ratio was high or when the level of Treg cells was low (CD4+/CD8+P<0.05 and Treg P<0.05). However, CD4+/CD8+and Treg are not independent prognostic factors for the DFS of TNBC cases. In other molecular subtypes of breast cancer, CD4+/CD8+ratio and the amount of Treg cells are not correlated with DFS (P>0.05). The level of NK cells is unrelated to the DFS of breast cancer with the four molecular subtypes (P>0.05). Conclusion:CD4+/CD8+ratio and the amount of Treg cells in peripheral blood may predict DFS of TNBC but are not considered as independent prognostic factors.

Peripheral T-cell lymphoma (PTCL) is a kind of highly aggressive lymphoma which contains a collection of subgroups. The patients with PTCL have poor prognosis under current chemotherapy regimens, so the treatment of PTCL remains a big challenge. Brentuximab vedotin combined with CHP regimen, pralatrexate in combination with romidepsin and other regimens have set up more options for patients with PTCL. Novel agents, such as PI3K inhibitors, which entered into clinical trials, bring good news to PTCL patients.

Epidermal stem cells (ESCs) play a critical role in homeostasis and wound repair of skin tissue. Since ESCs are rare (fewer than 10% in total basal cells population) and lack specific markers,it is difficult to isolate and identify them from keratinocytes. Currently ,isolation of ESCs was achieved mainly by fast adhesion of ESCs to extracelluar matrix or flow cytometry. Several specific markers have been found in recent years for the identification of ESCs.

Objective To investigate the feasibility and safety of transvaginal endoscopic cholecystectomy.Methods The clinical data of 88 female patients who underwent cholecystectomy at the Qilu Hospital of Shandong University from May to November, 2009 were retrospectively analysed. Among all the patients, 32 received transvaginal endoscopic cholecystectomy ( NOTES group) and the remaining 56 patients received laparoscopic cholecystectomy (LC). Thirty-two patients who received LC at the same period were selected (LC group)acccording to age, body mass index, type and severity of disease to conduct a matched case-control study. The differences in time span of postoperative pain, anodyne dose, enterokinesia recovery time, operation time, out-ofbed activity time, average hospital stay and hospitalization expenses between the two groups were compared using the paired t test. Results Cholecystectomies were successfully carried out for all the patients. The intraoperative blood loss, operation time, degree of pain, anodyne doses, enterokinesia recovery time, out-of-bed activity time,average hospital stay and hospitalization expenses were (5.7 ± 1.5 ) ml, ( 76 ± 27 ) minutes, 2.2 ± 0.6, ( 10 ±6) mg, (25±5) hours, (9±3) hours, (2.1 ±1.2) days and (1.12±0.34) ×104 yuan in NOTES group, and they were ( 13.9 ± 3.1 ) ml, (38 ± 16) minutes, 6.7 ± 1.5, (28 ± 8) mg, (45 ± 8) hours, (26 ± 6) hours,(4.3 ± 2.1 ) days and ( 1.54 ± 0.18 ) × 104 yuan in the LC group. There were significant differences between the two groups (t = 5.098, - 4.712, 2.417, 3.203, 3.089, 4.136, 4.786, 3.917, P < 0.05 ). Conclusion Transvaginal endoscopic cholecystectomy is safe and feasible, and it is superior to tranditional LC.
