Objective:To evaluate the effect of Arg and Gln enriched PN on nutrition status,immune function and stress status of gastric cancer patients after radical treatment.Methods:Eighty patients with gastric cancer were randomly divided into 4 groups: arg group(arginine enriched PN group),Gln group(glntamine supplemented PN group),Arg+Gln group(arginine and glutamine enriched PN group)and Rou group(Routine PN group).The distinct immune nutrients were added into PN in the different groups for 7 consecutive days.The difference of the patients' nutrition status,immune function and stress status were analyzed after operation.Results: The nutritional station and immunue fuction in Arg group,Gln group and Arg+Gln group were better than in Rou group on the 8th postoperative day.The concentration of CRP in the Arg+Gln group was different from that in other groups(P

Objective To observe the effects of hepatic artery reconstruction in rat with orthotopic liver transplantation(OLT)on ultrastructure changes of intrahepatic biliary epithelial cells after ischemia reperfusion iniury and postoperative biliary complications. Methods Male SD rats were divided into sham operation group (SO),OLT with hepatic artery reconstruction group(HA)and OLT without hepatic artery reconstruction group (NA).The liver tissue samples were collected at 0.5,3,6,12,24,36,48 hours after ischemia reperfusion in both HA grouD and NA group.The uhrastructure of intrahepatic biliary epithelial cells was observed by transmission electron microscope,and the morphometric analysis by the computer image analysis system.The postoperative biliary complications were also observed.Results In HA group and NA group,the injury of intrahepatic biliary epithelial cells aggravated gradually along with the reperfusion.The uhrastructure changes,such as enlarged mitochondria,blurred or disappeared cristae and decreased number of microvilli,were most significant at 24 hours and then recovered gradually.The mitochondrial average area and average perimeter were increased and the mitochondrial numerical densitv was decreased gradually along with the reperfusion.At 24,36,48 hours,the mitochondrial average area and average perimeter in NA group were significantly greater than those in HA group(t=-3.566,-7.780,-4.730,-4.610,-2.599,-5.730,P＜0.05).The average numerial density of mitochondia in NA group was significantly less than that in HA group at 36,48 hours(t=-4.619,4.000,P＜0.05).The incidence rate of biliary complications in HA group is significantly lower than that in NA group(x2=4.286,P＜0.05).Conclusions Hepatic artery reconstruction in rat with OLT has an protective effect on the uhrastructure of intrahepatic biliary epithelial cells after ischemia reperfusion.It is beneficial to the recovery of intrahepatic bile duct epithelial cells and can reduce the incidence rate of biliary complications.

Objective: To explore the security and the radical and clinical value of thoracoscopic-laparoscopic esophagectomy with two-field lymph node dissection for middle esophageal cancer through comparison with open esophagectomy. Methods: A total of 410 stage II to stage III esophageal cancer patients who underwent two-field lymph node dissection with two different methods (thora-colaparoscopic esophagectomy and open esophagectomy) from January 2009 to July 2013 in Uninon Hospital, Fujian Medical Universi-ty, were analyzed retrospectively. General pathological parameters, operative procedures, and short-term outcomes were collected and compared between the two groups (TLG and OG). Results: No significant differences were found regarding general pathological pa-rameters, such as gender, age, etc. Significant differences between thoracolaparoscopic and open two-field lymph node dissection esoph-agectomy were observed in terms of esophagectomy intraoperative blood loss [(206 ± 138) mL vs. (240±111) mL] and the mean num-ber of dissected lymph node per person [(26.6±8.6)/per vs. (21.7±9.2)/per]. Overall postoperative morbidity rate in OG was 35.2%, and its difference from that of TEG (25.8%) is statistically significant (P<0.05). Regarding single complications, such as pulmonary infec-tion and arrhythmia, OG showed evidently superior results (P<0.05). Meanwhile, anastomotic stricture and hoarseness rate are higher in TEG (P<0.05), and the difference was statistically significant as well. Conclusion: Thoracolaparoscopic two-field esophagectomy is technically feasible and safe and can achieve radical tumor resection.

ObjectiveTo explore the association between dietary retinol intake and prognosis of patients with esophageal squamous cell carcinoma. MethodsThe study enrolled 388 cases with primary esophageal squamous cell carcinoma that was pathologically diagnosed in the first affiliated hospital of Fujian medical university and the cancer hospital of Fujian medical university from July 2014 to August 2019. Chi-square test was used to determine the relationship between retinol and patients' characteristics. Kruskal-Wallis rank sum test was used to analyze the relationship between retinol and multiple nutrients. Cox proportional hazards regression model was used to explore the association between dietary retinol and esophageal squamous cell carcinoma. ResultsPatients with esophageal squamous cell carcinoma did not significantly differ in gender， age， TNM stage， tumor length or nutrient intake by different retinol intakes （P>0.05）. Multivariate Cox regression analysis showed that the high retinol intake group had a better prognosis （overal survial：HR=0.279，95%CI：0.150‒0.520，P<0.001；disease-free survival：HR=0.306，95%CI：0.181‒0.516，P<0.001）. ConclusionHigh dietary retinol intake may improve the prognosis of patients with esophageal squamous cell carcinoma.
