RESUMEN
Objective:To explore the effect of the surgery concept of rapid rehabilitation on the postoperative rehabilitation, immune function and nutritional status of patients with colorectal cancer undergoing laparoscopic radical surgery.Methods:From June 2017 to June 2019, 106 patients with colorectal cancer underwent laparoscopic radical surgery in the Affiliated Hospital of Shaoxing University of Arts and Sciences were divided into the observation group and the control group according to the random digital table method, with 53 cases in each group.The observation group adopted the surgery concept of rapid rehabilitation, while the control group adopted the surgery concept of conventional rehabilitation.The amount of intraoperative bleeding, postoperative complications and operation time were compared between the two groups.The recovery of gastrointestinal function, the changes of immune function and nutritional indicators were compared between the two groups.Results:There were no statistically significant differences in the amount of bleeding and operation time between the two groups(all P>0.05). The incidence of postoperative complications in the observation group was 5.66%(3/53), which was lower than 24.53%(13/53) in the control group(χ 2=7.361, P<0.05). The time of first anal exhaust[(2.14±0.32)d] and first eating[(1.85±0.42)d]in the observation group were shorter than those in the control group[(3.62±0.61)d and (2.79±0.36)d]( t=15.642, 12.371, all P<0.05). Three days after operation, the CD 3+ [(50.82±2.31)%], CD 4+ [(34.01±2.19)%]and CD 4+/CD 8+ (1.03±0.08) in the observation group were higher than those in the control group[(46.30±2.68)%, (30.26±2.05)% and (0.81±0.12)]( t=9.300, 9.101, 11.105, all P<0.05). The serum transferrin[(1.97±0.14)g/L]and prealbumin[(0.23±0.03)g/L] in the observation group were higher than those in the control group[(1.72±0.15)g/L and (0.18±0.03)g/L]( t=8.870, 8.580, all P<0.05). Conclusion:The surgery concept of rapid rehabilitation can promote the postoperative rehabilitation of patients with colorectal cancer, improve the immune function and nutritional status of patients, and has less complications.
RESUMEN
Objective To retrospectively analyze the efficacy of radiotherapy on nasal NK/T-cell lymphoma, and to explore the prognostic factors. Methods Between January 2000 and December 2008, 62 patients with nasal NK/T-cell lymphoma were treated with radiotherapy in our hospital. Their clinic data and efficiency were reviewed retrospectively. Kaplan-Meier methods were applied in unifactorial analysis and the COX regression model was applied in multivariate analysis. Results The median overall survival time was 69.7 months (95 % CI, 63.0-78.0 months), and 3, 5-year survival rate was 66.1% and 46.8 %. Metastasis was 61.8 % for the first reason which resulted in failure. The median survival time was 72.6 months in the increased group of numbers of T lymphocyte CD3 and 39.6 months in the decreased group, the difference was significant(x2 =4.9309, P =0.0264). Multivariate analysis confirmed that modified IPI 0-1 (x2 = 7.5266, P =0.0061), the numbers increased for CD3 (x2 =9.0912, P =0.0266), and complete remission(x2 = 9.0912, P =0.0106) were significant favorable prognostic factors for survival. Conclusion The radiotherapy was effective for patients with nasal NK/T-cell lymphoma, but was failure on account of distant metastasis, so systematic therapy still has an important role. modified IP1 0-1, the number increased for CD3 and complete remission were significant favorable prognostic factors for survival.
RESUMEN
Objective To study the effect of CT scanning condition on the target position coordinate with WIMRT radiotherapy planning system using the" Z" form localizing frame. Methods The whole Head Phantom containing three metal targets was scanned under the following conditions: localizing frame transver-sally tilting, CT gantry tilting and localizing frame axially tilting. Then the three target coordinates were com-puted respectively and compared with those under the standard condition. Results The height and width of coordinate under the localizing frame transversally tilting condition deviated from those under the standard scanning condition,which was in an angle dependent manner. On the other hand ,a tendency was shown that the greater the absolute height value of the targets coordinate, the greater the width value deviation. And so was the relation between the absolute width value of the coordinate and height value deviation. If CT gantry angle was not zero degree or localizing frame axis is not in the same line with the CT bed moving direction, the calculated longititude value of the targets coordinate was mainly affected. Conclusions CT scanning must be performed strictly under the standard localizing scanning condition by a proficient physicist.
