Résumé
Objective@#To investigate the changes of perioperative immune index in patients with breast cancer and its clinical significance.@*Methods@#Th1 cells, Th2 cells, Th1/Th2 ratio and regulatory T cells (Treg) were detected in peripheral blood of 103 patients with primary breast cancer and 116 patients with breast fibroma before surgery and on the 1st, 3rd and 5th day following operation. The relationship of changes in T lymphocyte subsets and clinicopathological characteristics, as well as tumor-free survival of breast cancer patients, was analyzed.@*Results@#The levels of Th1 cells in breast cancer group on the 1st, 3rd and 5th day following operation were (12.20±0.45)%, (13.89±0.47)%, (14.04±0.49)%, which were significantly lower than those before operation [(15.82 + 0.51)%, all P<0.05 ]. Treg cells, however, with the number of (3.82±0.13)%, (3.25±0.11)%, (2.95 ±0.11)%, were remarkably higher than those before operation [(2.53 ±0.11)%, all P<0.05]. With respect to breast fibroma patients, there was no significant difference compared with those before operation of Th1 cells, Th2 cells and Treg cells (all P>0.05). The changes of Th1 cells were associated with the degree of differentiation, T stage, N stage, TNM stage, HER-2 status and Ki-67 (all P<0.05). Treg cells were related to T stage, N stage and HER-2 status (all P<0.05). Tumor-free survival in the Th1-cell-increasing group was significantly better than that in the Th1-cell-decreasing group (P=0.045), while cell-decreasing group of Treg showed the improved outcomes (P=0.012).@*Conclusions@#The levels of Th1 cells and Treg cells are important indicators of cellular immune function in patients with breast cancer. Moreover, the perioperative changes of Th1 cells and Treg cells are associated with the size of tumors, pathological parameters, clinical stages and tumor-free survival outcomes.
Résumé
Objective To compare the clinical effect of unarmed cardiopulmonary resuscitationand cardiopulmonary resuscitationmachine in the emergency room.Methods One hundred cases patients with cardiopulmonary arrest in Hainan Agricultural Reclamation General Hospital from February 2014 to February 2016 were analyzed.The control group(n=50) were given unarmed cardiopulmonary resuscitation,while thetest group(n=50) were given ardiopulmonary resuscitation machine.Two groups' before and after cardiopulmonary resuscitation of arterial blood gas index(oxygen saturation (SaO2),C02 partial pressure (PaC02),oxygen partial pressure(Pa02)),cardiopulmonary resuscitation effectiveness and the success rate,and complications were compared.Results Before cardiopulmonary resuscitation,there were no significant differences on arterial blood gas index (SaO2,PaCO2,PaO2) between the two groups (t =0.069,0.097,0.121,P ＞ 0.05).After cardiopulmonary resuscitation,the SaO2,PaO2 of the test group were higher than that of the control group ((98.60± 8.51) ％ vs.(86.37 ± 7.84) ％,(13.84 ± 1.40) kPa vs.(8.69± 1.21) kPa),while PaCO2 of test group was lower than the control group ((3.24 ± 0.56) kPa vs.(6.41 ± 0.87) kPa),the differences were significant(t =7.474,21.665,19.679,P ＜ 0.05).The cardiopulmonary resuscitation of effective rate,success rate of test group were higher than the control group (84.00％ (42/50) vs.62.00％ (31/50),26.00％ (13/50)vs.10.00％(5/50),x2=6.139,4.336,P＜0.05).The total complication rate of the test group was lower than the control group(8.00％ (4/50) vs.28.00％ (14/50)),the difference was significant (x2 =6.775,P ＜0.05).Conclusion The clinical effect of cardiopulmonary resuscitation machine is significantly superior to unarmed cardiopulmonary resuscitation,which can effectively improve the patient's arterial blood gas state,improve the efficiency and success rate of cardiopulmonary resuscitation,and reduce the complications.
