ABSTRACT
Objective To explore the effect of rapid intestinal preparation combined with probiotics in bowel preparation before operation.Methods 124 colorectal cancer patients were divided into the probiotic group(65 cases) and control group(59 cases).Control group using traditional 3d bowel preparation,joint probiotic group,to give patients in the 1 d intestinal ready on the basis of probiotic oral.The two groups after patients received isonitrogenous and caloric nutritional support,were observed after the two groups of patients with body temperature and heart rate changes; detection of bacterial DNA ratio of whole blood.Observed in peripheral blood leukocyte count,and systemic inflammatory response syndrome(SIRS) and the occurrence of complications.Results Probiotic group and control group,postoperative fever duration and postoperative heart rate and leukocyte counts return to normal a short time( t =11.52,20.07,P ＜ 0.05 ) ; whole blood PCR detection of bacterial DNA after the positive test group 2 cases (3.30％),the control group was 8 cases ( 26.67％ ),the difference was statistically significant ( t =5.07,x2 =34.68,P ＜ 0.05 ).Postoperative SIRS rate and the incidence of complications showed no statistical difference ( P ＞ 0.05 ).Conclusion Probiotics could reduce colorectal cancer patients with postoperative intestinal permeability and reduce the incidence of bacterial translocation and its rapid intestinal preparation method was feasible and effective and knot the protection of the intestinal mucosal barrier function in rectal cancerconductive to knot the early postoperative inflammatory response in patients with rectal cancer recovery.
ABSTRACT
Objective To investigate the irfluence of PET/CT positioning on the effect of late-course accelerated hyperfractionated and three-dimensional conformal radiotherapy for stage Ⅲ lung squamous cell carcinoma.Methods 79 stage Ⅲ lung squarnous cell carcinoma patients were enrolled and divided into PET/CT group(n =37 cases,PET/CT positioning) and general CT group (n =42 cases,general CT positioning) according to the way of positioning.The conventional fractionated 3 DCRT( about 40 Gy) was used in previous 2/3 time and hyperfractionated( about 1.5 Gy) was used in later 1/3 time.Both groups used chemotherapy as adjuvant therapy.Full course of the treatment was a month or so.And the clinical efficacy and a variety of adverse reactions of the two groups was observed.Results The total rate of remission in PET/CT group were 73.0％,and 71.4％ in general CT group,and there was no significant difference in the two groups (x2 =1.347,P ＞ 0.05 ).The major radiation injury were radioactive pulmonary injury and tracheal damage,incidence rates were 56.8％and 57.1％ in acute stage,and there was no significant difference in the two groups( x2 =2.178,P ＞ 0.05 ) ; but in late stage 69.0％ in general CT group was significantly higher than 62.2％ in PET/CT group(x2 =4.142,P ＜0.05).Ater followed-up 1 year,the recurrence rate of hillar and mediastinal lymph node in PET/CT group was 43.7％,lower than that of the general CT group( 59.4％ ) ( x2 =4.732,P ＜ 0.05 ).Conclusion PET/CT positioning in late-course accelerated hyperfractionated and three-dimensional conformal radiotherapy for stage Ⅲ lung squamous cell carcinoma could reduce late stage radioactive pulmonary injury and tracheal damage,lower the recurrence rate of hillar and mediastinal lymph node.
