RESUMO
Background and purpose:Previous researches have shown that intravenous amino acid infusion during general anaesthesia prevents the decreases in core temperature. This study aimed to investigate the effect of amino acid infusion on postoperative liver and renal function in elderly patients undergoing gastrointestinal surgery. Methods:Forty ASAⅠ orⅡ patients (33 males, 7 females) aged 65-75 years undergoing elective gastrointestinal can-cer operation under epidural block combined with general anesthesia were randomly divided into 2 groups (n=20 each). GroupⅠ received intravenous infusion of mixed amino acids at a rate of 2 mL·(kg·h) -1 from induction of anesthesia to the end of operation (AA group); GroupⅡ received infusion of equal volume of normal saline (NS group). Snuff temperature was monitored for induction of anesthesia immediately, after 90 min and at closed abdomen. Renal and hepatic function was performed regularly before operation and on the 1st and 7th postoperative day.Results:The naso-pharyngeal temperatures at 90 min after the beginning of surgery and the time when the peritoneum was closed in AA group were signiifcantly higher than those in NS group (P0.05).Conclusion:Intraoperative amino acid infusion has no signiifcant effects on the renal or hepatic function in elderly patients undergoing gastrointestinal surgery.
RESUMO
Objective Study the drug resistance trend of Helicobacter pylori (H.pylori) based on polynomial regression equation to provide reference for clinical medication.Methods A total of 3496 clinical isolates of H.pylori collected from 2007 to 2012 were used for drug sensitivity test of six common-used drugs to evaluate the resistance rate of each drug.Correlation analysis were performed on each of the two drugs.Constructed log curve,exponential curve,inverted exponential curve,polynomial curve and sigmoid curve for each kind of drug resistance rate and did regression analysis for each drug resistance rate.Results According to the results of drug sensitivity test from 2007 to 2012,amoxicillin,furazolidone and gentamicin had strong antibacterial activity to H.pylori and got a lower drug resistance rate.The resistance rate of levofloxacin and clarithromycin were increasing year by year and the resistance of metronidazole had been maintained at a high level.The predictive drug resistance rate of clarithromycin,metronidazole,levofloxacin,amoxycillin,gentamicin and furaxone in 2013 were 21.49％,95.47％,20.70％,0.10％,0.09％ and 0.10％,respectively.The results were consistent with those of H.pylori infection rate in Southeast China performed by Jianzhong Zhang.Conclusion A certain quantitative relationship exists between the time and the helicobacter resistance rate.The established model can be used to predict the future trend of H.pylori resistance rate.It can be used to guide clinical rotation,the restriction of the use of antibiotics,and to reduce the generation of antibiotic resistant bacteria.

ObjectiveTo determine the effect of total mesorectal excision with double anastomosis instruments(DAIs) in lower rectal carcinoma. MethodsFrom 1995 to 1998,57 cases of middle and lower segement rectal carcinoma were treated by total mesorectal excision with DAIs, and were followed for 3 years. Results No operative death and no anastomotic leakage were noted. Two patients suffered from anastomotic stenosis,but no dysuria and sexual dysfunction occurred. Local recurrence rate was 5.3%(3/57)in the follow-up period. ConclusionsTotal mesorectal excision with DAIs is not only an effective method to maintain pelvic organ function in lower rectal cancer, but also able to improve the living quality of patients and reduce local reccurence.

RESUMO
Objective To detect the protective mechanism of trehalose in tracheal cryopreservation.Methods Inbred male Sprague-Dawley (SD) rats were sacrificed with intraperitoneal injection of ketamine(150mg?kg -1).The tracheas were removed and immersed immediately in the freezing medium of low potassium dextran (LPD) solution only(Group Ⅰ) ,containing with 10% dimethylsulfoxide(DMSO)(Group Ⅱ), containing with 0.15mol?L -1 trehalose (Group Ⅲ),and containing with 10% DMSO and 0.15mol?L -1 trehalose (Group Ⅳ) respectively. A sterile plastic tube containing a 1-cm-long trachea was filled with the freezing medium,sealed,and frozen to -80℃ at rate of -1℃ per minute in a programmable freezer.Then the tube was stored in liquid nitrogen(-196℃) for 20 days. Then the specimen was thawed in a 37℃ water bath and rinsed with physiologic saline solution 10 times.Histologic changes before cryopreservation and after thawing were examined in each group. After the specimens were embedded in paraffin,5-(m-thick sections were stained with hematoxylin and eosin.The epithelium and cartilage was assessed. We also observed Bcl-2 and Bax gene expression by immunohistochemistry. At last, some tracheas(SD) after cryopreservation were thawed and transplanted into the abdominal cavity of Wistar rats. The transplanted tracheas were retrieved and assessed histologically.Results Microscopic findings of the tracheas in Group Ⅲ and Group Ⅳ showed their structure were intact and Bax gene expression was lower in cartilage after cryopreservation(20d) compared with other groups,especially in Group Ⅳ.The tracheas in Group Ⅲ and Group Ⅳ grew well after they were transplanted into cavity of Wistar rats heterotopically,too.There were no significant differences among 4 groups in Bcl-2 gene expression.Conclusion In tracheal cryopreservation the trehalose can protect the trachea by protecting the tracheal cartilage.It is one of the protective mechanism that the trehalose inhibit the Bax gene expression of cartilage cells.The concomitant use of trehalose and DMSO has a synergistic effect.
