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.

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.

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.

Objective To evaluate the performance of a DNA microarray method for detecting HBV antiviral drug-resistant mutations. Methods Two hundred and twenty four serum samples from patients with CHB were tested in parallel by DNA microarray and direct sequencing for the mutations within the HBV reverse transcriptase (rt) region, which included rtL180, rtA181, rtM204 and rtN236. Samples with discrepant results were retested by clonal sequencing. Results Complete concordance between DNA microarray and direct sequencing results was observed in 214 out of 224 samples (95. 5% ). The presence of mixed viral populations in the other 10 samples detected by DNA microarray but not by direct sequencing was confirmed by clonal analysis. The DNA microarray could detect minor viral populations which constituted 5.0%-15. 0% of the total viral load. Conclusion DNA microarray is highly consistent with direct sequencing in detecting HBV mutations conferring drug resistance and more sensitive in detecting mixed mutant and wild-type sequences than direct sequencing, which makes it a useful tool for early detection of drug resistance early.

Currently,independent clinical medial femoral plate is more needed to apply in more complex C3 distal femoral fractures and knee valgus orthopedic surgery.The doctors always pre-bent the contralateral femoral lateral plate in order to achieve close to the natural shape of the bone.The cold deformation of the plate can change the metallographic structure and the biomechanics,and the position of the screw holes in the plate may also affect the healing of fractures.Compared with traditional manufacturing techniques,3D printing technology as a core technology in third industrial revolution,instead prior manufacture of molds,removing the large amount of material in the manufacturing process and the complex process of forging a final product,it is more suitable for difficult to machine materials,manufacture,inspection shape design,assembly,testing and fast reverse engineering.Therefore,a personalized interior distal femoral plate with 3D printing technology was designed,and the application of the plate,the current situation and prospects of 3D printing technology and other aspects were summarized in this article.

Objective To evaluate the relationship between the spatial structure of pulmonary vascular tree and oxygen partial pressure in patients with chronic obstructive pulmonary disease(COPD) by the fractal dimension method.Methods 106 patients with COPD and 100 healthy people without COPD as controls were included in this study.All of the patients underwent multidetector CT scan and blood gas analysis.The pulmonary vascular trees were generated using post-processing software,and the FD of the pulmonary vascular trees were determined with ImageJ software in a personal computer.The fractal dimension were evaluated in the two groups.The relationship between FD and oxygen partial pressure in patients with COPD was analyzed.Results The FD value of the patients with COPD was lower than that of the patients without COPD (t =5.21,P＜ 0.01).There was a significant correlation between FD and the PaO2 in patients with COPD (r=0.692,P＜ 0.01).Conclusion FD analysis can effectively evaluate the process of pulmonary vascular remodeling induced by hypoxia in patients with COPD,which may be used as an important index for quantitative evaluation of pulmonary vascular remodeling in the course of COPD.

Objective Sylvian Veins morphology analysis contributes to cortex veins protection for clear surgical fields, a better choice for operation plan evaluation. Methods 33 cases diagnosed as epilepsy, male∶female=19∶14, mean ages 18.7y (9-52). Results 4 types of Sylvian Veins spreading were observed from the procession of functional surgery: long stem pattern 49%(16/33), short stem pattern 15%(5/33), long truncks pattern 33%(11/33), and absent stem pattern 3%(1/33). Conclusion Sylvian Veins morphology analysis shows that there exist 4 main patterns, which may contribute to functional surgery about frontal operculum, temporal operculum and insular lobe or intracranial electrode placement.

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.
