ABSTRACT
Objective To Discuss the effect of surgical treatment from enteral and parenteral nutrition that in perioperative period of hepatolithiasis patients who taking hepatectom.Methods Retrospective analysis 55 cases who taking hepatectomy treatment in Fuling Central Hospital of Chongqing City from March 2011 to March 2015,all elective operations.According to the different nutrition support methods in perioperative period,randomly divided into enteral and parenteral group (n =25) and parenteral nutrition group (n =30).Results The postoperative complication rate and recovery time of bowel function in patients with enteral and parenteral nutrition,it was better than parenteral nutrition group (28 ％ vs 40％),[(4.50 ± 0.50) d vs (5.50 ± 1.00) d],the difference had statistical significance (P ＜ 0.05).Before and after operation in two groups of body mass index [(22.10 ± 1.80) vs (22.30 ± 1.70)],prealbumin impovement [(130.00 ± 45.00) mg/L vs (124.00 ± 55.00) mg/L],albumin impovement [(35.50 ± 2.72) g/L vs (36.50 ± 2.70) g/L],had no statistical significance (P ＞ 0.05).Conclusion Enteral and parenteral nutrition in perioperative can significantly improve the nutritional status of patients and the effect of surgical treatment.
ABSTRACT
Objective To study the effects of social isolation (SI)on the spatial and nonspatial cognitive ability in mice.Methods The postnatal 21 day kunming mice were divided into control group,SI 2 weeks group,SI 4 weeks group,SI 8 weeks group and SI 2 weeks gregarious group according to randomized block design,with ten animals each.SI 2 weeks group,SI 4 weeks group and SI 8 weeks group were isolated for 2,4 and 8 weeks respectively,SI 2 weeks gregarious group would be housed under normal grouped housing condition after 2 weeks isolation until adult,the relative control groups were the same age as the relative SI and SI gregarious group.All animals were measured the spatial and nonspatial cognitive ability by carrying the object recognition test(ORT) and object location test (OLT) after the treatment.Results In the ORT,compared to the relative control group,the discrimination index in the SI 2 weeks group,SI 4 weeks group and SI 8 weeks group ( ( - 0.03 ± 0.003 ),( - 0.11 ±0.02) and( - 0.21 ± 0.02 ) respectively) were strikingly lower than the relative control group ( ( 0.29 ± 0.03 ),(0.13±0.07) and (0.09 ±0.03) respectively) (P＜0.05).In the OLT,compared to the relative control group,the discrimination index in the SI 2 weeks group,SI 4 weeks group and SI 8 weeks group( ( -0.15 ±0.02),( -0.30± 0.02),( - 0.32 ± 0.02 ) respectively ) were strikingly lower than the relative control group ( (0.33 ± 0.02 ),(0.41 ± 0.03 ),(0.27 ± 0.04)respectively)(P＜ 0.05 ),while the SI 2 weeks gregarious group with the resocialization to the normal housing condition showed no change.Conclusions 2 weeks,4 weeks and 8 weeks isolation on mice lead to the spatial and nonspatial cognition deficits,while the resocialization to the normal housing condition could recover the damage.
