Chinese Journal of Anesthesiology 2011;31(4):404-406
Objective To evaluate the influence of different methods of anesthesia on the glucose metabolism of leukocytes in elderly patients undergoing colorectal cancer surgery. Methods Fifty ASA Ⅰ or Ⅱ patients, aged≥65 yr, with body mass index 18-25 kg/m2, scheduled for elective colorectal cancer surgery, were randomly divided into 2 groups ( n = 25 each) : sevoflurane anesthesia group (Sevo group) and sevoflurane anesthesia combined with epidural block group ( S + E group) . The patients in S + E group underwent epidural catheterization, and 2% lidocaine 3 ml was given via the epidural catheter. If no signs of spinal anesthesia were confirmed 5 min later, the mixture of 1% lidocaine and 0.2% tetracaine 8-10 ml was given, and an increment of the mixture 4-5 ml was given every 50 min. During the operation, the end-tidal concentration of sevoflurane was maintained at 0.7 MAC in S + E group and at 1.0 MAC in Sevo group. The depth of anesthesia was adjusted according to the BIS value in both groups. Venous blood samples were taken at 10 min before operation (T1 ), and 60 min, 24 h.and 5 days after the end of operation (T2-4 ) for WBC count and measurement of activities of pyruvate kinase (PK)and glucose-6-phosphate dehydrogenase (G6PD) in the leukocytes. Results Compared with T1, the WBC count at T3 in both groups, the PK activity at T, in group S+E and G6PD activity at T, in group Sevo and at T3,4 in group S + E were significantly increased ( P < 0.01) . Compared with group Sevo, the PK activity at T, and G6PD activity at T3,4 were significantly increased in group S+E ( P < 0.05) . There was no significant difference in the WBC count between the two groups ( P > 0.05) . Conclusion There is no significant change in the WBC count when the two methods of anesthesia are used in elderly patients undergoing colorectal caner surgery, however, sevoflurane anesthesia combined with epidural block enhances the leukocyte function in elderly patients compared with sevoflurane anesthesia alone.

BACKGROUND: Vascular endothelial growth factors are a family of multifunctional cytokines that can enhance vascular permeability, induce angiogenesis, promote endothelial cel growth and migration, and inhibit cel apoptosis.
OBJECTIVE:To elaborate the latest progress in the role of vascular endothelial growth factor and its receptors in the corneal tissue.
METHODS:A computer-based search of PubMed databases was performed for relevant articles published from 2005 to 2015. The key words were “vascular endothelial growth factor, cornea”. According to the inclusion and exclusion criteria, 43 articles were included in result analysis.
RESULTS AND CONCLUSION:Vascular endothelial growth factor and its receptors are involved in the regulation of corneal neovascularization by causing Tip cel activation that affects the Notch signaling pathways. Corneal lymphatic regeneration mainly relies on macrophages to secrete vascular endothelial growth factor-C or vascular endothelial growth factor-D that further activate vascular endothelial growth factor receptor-3 in the lymphatic endothelial cels to cause cel proliferation and migration, and eventualy lead to the formation of new lymphatic vessels. But herpes simplex keratitis HSK induces the corneal lymphatic regeneration by vascular endothelial growth factor-A/vascular endothelial growth factor receptor-2 pathway. Vascular endothelial growth factor family can significantly improve the damaged corneal nerve endings, epithelium and corneal sensitivity, has the function of nerve nutrition and promote restoration of the corneal epithelium.

Objective To investigate the efficacies of laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery in the treatment of patients with different body mass indexes (BMI) and type 2 diabetes mellitus.Methods The clinical data of 40 patients with type 2 diabetes mellitus who underwent LRYGB surgery at the Shengjing Hospital of China Medical University from January 2013 to December 2013 were retrospectively analyzed.According to different BMI,8 patients with BMI < 27.5 kg/m2 were allocated into group 1,14 patients with BMI≥27.5 kg/m2 and <32.5 kg/m2 in group 2 and 18 patients with BMI≥32.5 kg/m2 in group 3.Forty patients were followed up via telephone interview and food habits questionnaire by weight loss file managers of Shengjing Hospital and the fourth Affiliated Hospital of China Medical University.All the patients received the reexamination of blood test and data collection at postoperative year 1.The preoperative and postoperative 1-year fasting plasma glucose,glycosylated hemoglobin (HbA1 c),BMI and C-peptide were collected and detected.The fasting plasma glucose < 7.00 mmol/L and HbA1 c < 7.00% were used as a standard of complete remission.Count data and comparison of rates were analyzed using the chi-square test.Measurement data with normal distribution were presented as x ± s and analyzed by the t test.Skew distribution data were described as M (range) and analyzed by the Wilcoxon rank sum test.Repeated measurement data were analyzed by the repeated measures ANOVA.Results Forty patients received successful LRYGB surgery without perioperative complications,and were followed up for 1 year at the Shengjing Hospital (23 patients),the fourth Affiliated Hospital (8 patients) and other hospitals (9 patients).Of the 40 patients,85.0% (34/40) of patients had no postoperative long-term obvious malnutrition,anastomotic stenosis,ion disorders and digestive tract dynamic obstacles,15.0% (6/40) of patients were not adapted to the change of life habits such as frequent nausea and vomiting.Five patients with different degrees of frequent vomiting,abdominal pain and night heartburn within postoperative 1 month had the remission of synptoms after symptomatic treatment.One patient in group 2 had a symptom of hypertonic coma due to intake of oral high-sugar drinks at postoperative 1 week and then was cured by hospitalization.The fasting plasma glucose,HbA1c and BMI in group 1 from preoperation to postoperation were decreased from 11.07 mmol/L (range,6.00-17.00 mmol/L) to 7.18 mmol/L (range,6.00-15.00 mmol/L),from 8.85% (range,6.00%-11.00%) to 6.35% (range,6.00%-9.00%) and from 26.0 kg/m2 (range,22.0-27.0 kg/m2) to 22.2 kg/m2 (range,20.0-25.0 kg/m2),with significant differences (F =2.413,3.256,6.750,P < 0.05).C-peptide from preoperation to postoperation was decreased from 1.20 nmol/L (range,1.00-3.00 nmol/L) to 1.07 nmol/L (range,1.00-2.00 nmol/L),with no significant difference (F =1.678,P > 0.05).The remission rate of diabetes in group 1 was 3/8.The fasting plasma glucose and HbA1c in group 2 from preoperation to postoperation were decreased respectively from 10.73 mmol/L (range,7.00-19.00 mmol/L) to 5.89 mmol/L (range,5.00-9.00 mmol/L) and from 8.00% (range,6.00%-15.00%) to 5.85% (range,5.00%-8.00%).The BMI from preoperation to postoperation was decreased from 31.0 kg/m2 (range,29.0-32.0 kg/m2) to 25.5 kg/m2 (range,21.0-29.0 kg/m2),with significant differences in the above 3 indexes (F =5.449,4.008,-3.296,P < 0.05).C-peptide from preoperation to postoperation was decreased from 1.53 nmol/L (range,1.00-5.00 nmol/L) to 1.52 nmol/L (range,1.00-6.00 nmol/L),with no significant difference (F =-0.251,P > 0.05).The remission rate of diabetes in group 2 was 10/14.The fasting plasma glucose,HbA1c and BMI in group 3 from preoperation to postoperation were decreased from 9.44 mmol/L (range,5.00-16.00 mmol/L) to 6.65 mmol/L (range,4.00-15.00 mmol/L),from 7.90% (range,6.00%-11.00%) to 6.45% (range,5.00%-9.00%) and from 36.9 kg/m2 (range,33.0-47.0 kg/m2) to 27.7 kg/m2 (range,23.0-34.0 kg/m2),with significant differences (F =-3.027,-3.410,-3.724,P < 0.05).C-peptide from preoperation to postoperation was decreased from 2.91 nmol/L (range,0.00-9.00 nmol/L) to 2.13 nmol/L (range,0.00-6.00 nmol/L),with no significant difference (F =-3.724,P > 0.05).The remission rate of diabetes in group 3 was 14/18.There was no significant difference in the remission rate of diabetes of 3 groups (x2 =4.460,P > 0.05).There were significant differences in the changing trends of fasting plasma glucose and BMI among the 3 groups (F =3.200,22.500,P < 0.05).There were no significant differences in the changing trends of HbA1c and C-peptide among the 3 groups (F =0.720,1.640,P > 0.05).Conclusion LRYGB surgery is feasible for the treatment of type 2 diabetes mellitus with effectively decreasing fasting glucose,and should be performed on patients with BMI ≥ 27.5 kg/m2 instead of patients with BMI < 27.5 kg/m2 according to a correlation of blood glucose control and preoperative BMI.
