ABSTRACT
Objective To discuss the clinical value of bile reinfusion via nasojejunal tube on liver function after biliary tract surgery. Methods Eighty patients with biliary tract surgery and bile outer drainage were divided into bile reinfusion group and control group by random digits table method with 40 cases each. The clinical data concerning the liver function and volume of biliary drainage were collected. Results The patients were well tolerated for bile reinfusion, and abdominal distension, nausea and vomiting occurred in some patients. The symptoms improved significantly after symptomatic treatment. The alanine aminotransferase (ALT) and total bilirubin (TBIL) levels at the fifth day after operation in bile reinfusion group were significantly reduced than those in control group:(31 ± 18) U/L vs. (48 ± 32) U/L and (51 ± 32)μmol/L vs. (76 ± 38)μmol/L, the aspartate aminotransferase (AST) and ALT levels at the seventh day after operation in bile reinfusion group were significantly reduced than those in control group: (32 ± 19) U/L vs. (43 ± 26) U/L and (20 ± 19) U/L vs. (31 ± 22) U/L, and there were statistical differences (P<0.05). The volume of biliary drainage in the bile reinfusion group was significantly increased compared with that in control group at the third and fourth day after operation:(485 ± 52) ml vs. (428 ± 96) ml and (509 ± 62) ml vs. (458 ± 59) ml, and there was statistical difference (P<0.01). Conclusions Bile reinfusion via the nasojejunal tube may facilitate the recovery of liver function after biliary tract surgery.
ABSTRACT
Objective To explore the effect of carbohydrate administration on postoperative insulin resistance after gastroenteric tumor resection.Methods Sixty elective gastroenteric tumor resection patients were divided into observation group and control group by random number table method,with 30 cases in each.Observation group was given carbohydrate administration before surgery,that was 2 h before anesthesia oral carbohydrates 300 ml containing 50 g glucose;control group was treated according to the traditional methods,preoperative fasting 12 h,6 h forbidden to drink.The blood samples were collected to measure the levels of fasting blood glucose (FBG) and fasting insulin (FINS) at 3 h before operation and 1,3,7 d postoperation respectively.Homeostasis model assessment (HOMA) was applied to calculate the insulin resistance index.Results The levels of FBG,FINS,HOMA-IR at 1,3 d postoperation in two groups were significantly higher than those at 3 h preoperation [observation group:(10.65 ± 1.78),(7.32 ± 1.48) mmol/L vs.(5.09 ±0.43) mmol/L,(25.78 ± 12.43),(16.23 ±7.56) mU/L vs.(10.48 ± 1.57) mU/L,11.67 ±6.32,5.12 ± 2.11 vs.2.35 ± 0.54;control group:(11.18 ± 1.25),(8.04 ± 1.53) mmol/L vs.(5.12 ± 0.39) mmol/L,(39.67 ± 10.37),(24.34 ± 6.78) mU/L vs.(9.98 ± 2.04) mU/L,19.07 ± 5.49,8.56 ± 2.87 vs.2.28 ± 0.39](P ＜ 0.05).The levels of FINS,HOMA-IR at 1,3 d postoperation in control group were higher than those in observation group (P ＜ 0.05).The levels of FINS and HOMA-IR at 7 d postoperation in observation group were returned to the 3 h preoperative (P ＞ 0.05),while the levels in control group [(16.32 ± 4.56) mU/L,3.87 ± 1.12] was still higher than those at 3 h preoperation (P ＜0.05).Conclusion Carbohydrate administration may shorten the insulin resistance durion after gastroenteric tumor resection,and reduce the intensity of insulin resistance,thus contributing to the rehabilitation of patients.
ABSTRACT
Objective To assess the effect of preoperative carbohydrate preconditioning on postoperative insulin resistance and inflammatory response in patients after gastroenteric tumor resection.Methods Sixty patients with elective gastroenteric tumor resection were divided into preoperative carbohydrate preconditioning group and control group by random digits table with 30 cases each.Preoperative carbohydrate preconditioning group was given oral containing 50 g glucose carbohydrate 300 ml 2 h before surgery,and control group was given traditional method,fasting 12 h before surgery and water deprivation 6 h before surgery.The blood samples were collected to measure the level of fasting blood glucose (FBG),fasting insulin (FINS),interleukin (IL)-6 and C-reactive protein (CRP),3 h before surgery and 1,3,7 d after surgery respectively.Homeostasis model assessment insulin resistance index (HOMA-IR) was computed.Results There were no statistical differences in FBG,FINS,IL-6,CRP and HOMA-IR 3 h before surgery between the 2 groups (P ＞ 0.05).The FBG,FINS,IL-6,C RP and HOMA-IR in the 2 groups at 1,3 d after surgery were significantly higher than those 3 h before surgery,but those except for FBG in control group were significantly higher than those in preoperative carbohydrate preconditioning group [1 d after surgery:(39.67 ± 10.37) mU/L vs.(25.78 ± 12.43) mU/L,(98.67 ± 12.42) μg/L vs.(65.36 ± 16.72)μg/L,(121.74 ±11.32) mg/L vs.(82.18 ±4.36) mg/L,19.07 ±5.49 vs.11.67 ±6.32;3 d after surgery:(24.34 ±6.78) mU/L vs.(16.23 ±7.56) mU/L,(116.43 ± 18.57) μg/L vs.(78.53 ± 10.38) μg/L,(151.30 ± 10.46) mg/L vs.(129.29 ± 10.24) mg/L,8.56 ±2.87 vs.5.12 ±2.11],there were statistical differences (P ＜0.05).There were no statistical differences in FINS and HOMA-IR in preoperative carbohydrate preconditioning group between 7 d after surgery and 3 h before surgery (P ＞ 0.05),but there was statistical difference in control group (P＜ 0.05).There were no statistical differences in FBG,IL-6 and CRP in the 2 groups between 7 d after surgery and 3 h before surgery (P ＞ 0.05).There was no aspiration during anesthetic stage.Conclusion Preoperative carbohydrate preconditioning may shorten the insulin resistance time after gastroenteric tumor resection,reduce the intensity of insulin resistance,and improve inflammatory response,thus contributing to the rehabilitation of patients.
ABSTRACT
Objective To investigate the effect of preoperative carbohydrate fluid intake on postoperative insulin resistance and immune function.Methods Sixty elective gastroenteric tumor resection patients were randomly divided into test (n =30) and control (n =30) groups.Control group were fasted before surgery,while test group were given oral carbohydrate before surgery.The blood samples were collected to measure the levels of fasting blood glucose (FBG),fasting insulin (FINS),and cellular immunity (CD3 +,CD4 +,CD8 +,and CD4 +/CD8 +) before operation and 1,3,7 day postoperation,respectively.Homeostasis model assessment (HOMA) was applied to assess the status of insulin resistance.Results Compared to preoperation,the levels of CD4 +,CD4 + / CD8 +,and HOMA-IR at 1 day postoperation in both control and test groups were significantly higher (P ＜ 0.05).Compared to test group,the levels of CD4 +,CD4 +/CD8 +,and HOMA-IR at 1,3 day postoperation in control group were significantly higher (P ＜ 0.05).At the seventh day after surgery,HOMA-IR levels in the test group were returned to the preoperative level (P ＞ 0.05),while the control group was still higher than before surgery (P ＜ 0.05).There were no differences in CD4 + and CD4+/CD8 + at seventh days after surgery between two groups (P ＞ 0.05).Conclusions Preoperative carbohydrate administration may shorten the insulin resistance duration after gastrointestinal cancer surgery,reduce the intensity of insulin resistance,and improve immune function.Thus contributes to the rehabilitation of patients.
ABSTRACT
ObjectiveTo explore the expression of MRP1 and CD34 in colorectal carcinoma tissue and the relationship with clinicopathological factors.MethodsImmunohistochemical streptavidin-perosidase method was used to examine the expression of MRP1 and CD34 in 53 cases with colorectal carcinoma and normal colorectal tissue.The correlation between the levels of MRP1and CD34 expression and clinicopathological factors were analyzed.ResultsThe positive expression rates of MRP1 in the carcinoma group and normal colorectal tissue group were 49.1％ and 15.1％ respectively,and there was a significant difference of the positive expression between the two groups( x2 =14.029,P ＜ 0.01 ).The expression of MRP1 had no correlation with the degree of differentiation,the depth of invasion,the metastasis of lymph node and all the other clinicopathological factors ( P ＞ 0.05 ).CD34 value in the carcinoma group and normal colorectal tissue group were ( 35.63 ± 12.23 ) MVD/HP and ( 6.12 ± 0.97) MVD/HP,respectively,and there was a significant difference between the two groups (t =17.565,P ＜ 0.01 ).CD34 was not correlated with age,sex,tumor size,localization of the primary tumor ( P ＞ 0.05 ),but correlated with Dukes staging,lymph node metastasis,differentiation of the tumor,depth of invasion( all P ＜ 0.05).ConclusionThe overexpression of MRP1 and CD34 protein may involve in colorectal carcinogenesis;MRP1 may involve in the primary multidrug resistance in colorectal carcinoma.; CD34 may involve in the colorectal carcinoma invasion and metastasis.Investigating the expression of MRP1 and CD34 in colorectal carcinoma simultaneously can provide new referential indexes for the treatment and prognosis of colorectal carcinoma.
ABSTRACT
ObjectiveTo explore the value of immuomagnetic beads(IMB) technique for detection of intraperitoneal free cancer cells from colorectal cancer.MethodsPeritoneal lavage fluid was obtained from 80 patients with colorectal cancer during laparotomy.Peritoneal lavage cytology (PLC) and IMB were used to detect free cancer cells in peritoneal lavage fluid.10 patients with hysteromyoma during laparotomy were enrolled into the control group.ResultsThe positive rate of PLC was 8.8％ (7/80),the positive rate of IMB was 28.8％ (23/80).The positive case after useing PLC detect,IMB detect also was positive.The detected samples of control group were negative by these two methods.IMB was superior to PLC ( x2 =10.503,P =0.001 ).ConclusionIMB was more sensitive and specific than PLC,which could provide a effective method for finding intraperitoneal free cancer cells.
