RESUMO
Objective To explore the nutrition support route of enteral nutrition (EN) and parenteral nutrition(PN) on the cellular immune function of patients after esophagectomy.Methods Sixty-two patients with esophageal surgery were randomly divided into EN group and the PN group,and each was 31 cases.Cellular immune indexes(including T lymphocyte subsets,natural killer cells,B lymphocytes) were measured at the preoperation,the postoperative 1st day and 8th day.The t test was preformed to compare the measurement data of two groups,and repeated measures analysis of variance was used to compare multiple time points of measurement data of two groups.Results The levels of CD3,CD4,CD8,CD4/CDS,NK cells and B cells in EN group at before operation were (60.46 ± 6.41) ％,(39.03 ± 5.64) ％,(25.06 ± 5.39) ％,(1.60 ± 0.24),(13.86 ±4.91)％,(13.14 ± 3.81)％ respectively,and those indices at 8th day after operation were (65.18 ±7.81)％,(40.45 ±6.82)％,(22.81 ±4.47)％,(1.78 ±0.16),(16.97 ±4.85)％,(15.69 ± 3.88)％ respectively,and the differences were statistically significant(P ＜ 0.05).The levels of CD4,CD4/CD8,NK cells and B cells in PN group at before operation were (59.78 ± 5.17) ％,(39.10 ± 5.49) ％,(24.94 ± 3.97) ％,1.57 ±0.20,(14.02 ± 4.47) ％,(12.96 ± 3.39) ％ respectively,significantly different from that of 8th days ((59.78 ±5.17)％,(39.71 ±5.63)％,(24.74 ±3.80),(1.62 ±0.15),(15.35 ±4.31)％,(14.33 ±3.43) ％ respectively),and there were significant difference compared to before operation in terms of CD4,CD4/CD8,NK cells and B cells.At the 8th day after operation,there was significant difference between in EN group and PN group in terms of CD3,CD8,CD4/CD8,NK cells and B cells(P ＜0.05).Conclusion Early EN for patients after esophageal carcinoma operation can significantly improve the cellular immune function of patients.
RESUMO
Objective To investigate the significance of early postoperative enteral nutrition with esophageal cancer in the elderly. Methods A total of 62 cases of esophageal cancer patients aged 70 years and older were randomly divided into the enteral nutrition(EN)group and the parenteral nutrition(PN)group. In preoperative and the first day and eighth day of postoperative serum albumin,prealbumin,peripheral blood lymphocytes,serum immunoglobulin(IgG,IgM,IgA),complement C3 and C4 were measured,and the postoperative infectious complications and cardiovascular complications were observed. Results During the eighth day after operation,the statistic analysis of the data between EN group and PN group showed: tALB = 2. 535,tPA = 2. 880,tLymphocyte =2. 720,tIgA =2. 166,tIgM =2. 065 ,tC3 =4. 103 ,tC4 =2. 478,P ＜0. 05. The result indicated that the EN group was better than the PN group in improving the nutritional status of patients,strengthened the immune system. The complication comparison between the two groups after operation: x2 Infection = 4. 24,x2 Cardiovascular =15.55,P ＜ 0. 05. The result indicated that the EN group had lower incidence of infectious complications and cardiovascular complications than the PN group. Conclusions Early enteral nutrition can significantly improve the nutritional status of elderly patients with esophageal cancer after postoperative,enhance immunity,and reduce the incidence of complications.
RESUMO
Objective To explore the expression and significance of let-7a2 in lung adenocarcinoma.Methods To adapt technology of realtime PCR with reference of U6, the expression of let-7a2 in tumor tissues and normal tissues was detected in 15 cases of resected lung adenocarcinoma. The laboratorial data were analysed by measure of 2~(-△△CT) method. The analysed data were managed by statistics. Results The expression of let-7a2 in lung adenocarcinoma tissue was significantly lower than that in lung normal tissue (0.8733±0.4821 vs 2.4527±1.0111). This difference possess markedness significance(t=6.816, P<0.001).Conclusion The expression of let-7a2 in lung adenocarcinoma is obviously lower and is concerned with the course of lung cancer evolution.
RESUMO
Objective To probe into the indication, operative skill of intrapericardial pneumonectomy, the prevention and cure in postoperative complication of intrapericardial pneumonectomy for locally advanced lung canc-er. Methods The clinical data of 43 cases of locally advanced lung cancer undergoing intrapericardial pneumonec-tomy from February 1998 to November 2007 were retrospectively analyzed. Results No surgical death occurred. The main postoperative complication was arrhythmia, acute pulmonary edema and pneumonia, with incidence as 41. 86%. The 1-,3- and 5-year postoperative survival rate was 79.1% ,30.2% and 11.6%. Conclusions The intrap-ericardial pneumonectomy skill not only can improve resection rate, reduce exploration rate, but also offer more oppor-tunity of further therapy in a part of locally advanced lung cancer.
