Objective To evaluate the effectiveness of enteral immunonutrition for patients with acute pancreatitis. Methods The randomized controlled trials (RCTs) about enteral immunonutrition for patients with acute pancreatitis were searched in following databases: PubMed (1966 to August 2012), MEDLINE (Ovid, 1946 to August 2012), CENTRAL (Issue 3, 2012), CBM (1978 to August 2012), CNKI (1979 August 2012), VIP (1989 to August 2012), and WanFang Data (1977 to August 2012). The relevant materials and each reference of literature were also searched manually. Two reviewers independently screened the literature according to the predefined inclusion and exclusion criteria, extracted the data and assessed the quality, and then the meta-analysis was conducted by using RevMan 5.0 software. Results A total of 6 RCTs involving 197 patients were included. The results of meta-analysis showed that there were no significant differences between the enteral immunonutrition group and the routine enteral nutrition group in following aspects: infectious complications and mortality rate, length of stay, level of C-reactive protein and numeration of leucocyte after treatment, and APACHE II score. Conclusion At present, no evidence shows enteral immunutrition is superior to routine enteral nutrition in acute pancreatitis. For the quantity and quality limitation of the included studies, more high-quality and large-sample RCTs are required to investigate the proper ingredients and dosage of enteral immunonutrition suitable for patients with acute pancreatitis.
Objective To explore the factors of postoperative cough in lung cancer patients. Methods Totally 130 lung cancer patients of single medical team (average age of 58.75±9.34 years, 65 males and 65 females), from February 2016 to February 2017 in the Department of Thoracic Surgery of West China Hospital of Sichuan University, were investigated by Mandarin Chinese version of the Leicester Cough Questionnaire (LCQ-MC). We analyzed and calculated the preoperative and postoperative scores of LCQ-MC, Cronbach α and the influencing factor. Results The preoperative score of LCQ-MC's physiological dimension was significantly lower in the postoperative cough group (6.30±0.76) than that of the postoperative non-cough group (6.56±0.60,P=0.044), while the preoperative total score of LCQ-MC (19.53±1.78, 20.03±1.45) was not statistically different (P=0.080). The postoperative score of LCQ-MC was significantly lower in the postoperative cough group (17.32±2.79) than that of the postoperative non-cough group (19.70±1.39,P<0.001). And the scores of physiological, psychological and social dimension were significantly lower in the postoperative cough group (5.32 ±1.14, 5.73±1.14, 6.23±0.89) than those of the postoperative non-cough group (6.25±0.63, 6.67±0.54, 6.78±0.49) (P values were all less than 0.001). The result of multi-factor logistic regression analysis showed the condition of preoperative cough symptom (OR=0.354, 95%CI=0.126–0.994, P=0.049) and anesthesia time (OR=1.021, 95% CI=1.003–1.040, P=0.021) were the risk factors. Conclusion The risk factors of postoperative cough symptoms in lung cancer patients are the condition of preoperative cough symptoms and anesthesia time.
Objective To observe the level of vascular endothelium growth factor A( VEGF-A) in exhaled breath condensate ( EBC) of patients with acute lung injury/acute respiratory distress syndrome ( ALI/ARDS) , and investigate its clinical significance. Methods EBC of 23 patients with ALI/ARDS by mechanical ventilation in intensive care unit ( ICU) were collected with improved EcoScreen condenser. EBC of 17 normal control subjects were collected with EcoScreen condensor. The level of VEGF-A was measured by ELISA in EBC and serum. The levels of VEGF-A in EBC of patients with different grades of lung injuries were compared, and the correlation was analyzed between the level of VEGF-A and clinical indicators. Results The level of VEGF-A in EBC was lower in the patients with ALI/ARDS than that of control subjects [ ( 49. 88 ±6. 32) ng/L vs. ( 56. 50 ±6. 323) ng/L, P lt;0. 01] , the level of VEGF-A was higher in the ALI patients than that of ARDS patients [ ( 53. 56 ±5. 56) ng/L vs. ( 45. 86 ±4. 45) ng/L, P lt;0. 01] ,and higher in the survival patients than that of the died patients [ ( 51. 92 ±6. 28) ng/L vs. ( 46. 05 ± 4. 58) ng/L, P lt;0. 05] . The level of VEGF-A in EBC was negatively correlated with lung injury score and A-aDO2 /PaO2 ( r = - 0. 426 and - 0. 510, respectively, P lt;0. 05) , and positively correlated with PaO2 /FiO2 and PaO2 ( r =0. 626 and 0. 655, respectively, P lt; 0. 05) . The level of VEGF-A in serum was not different between the ALI/ARDS patients and the control subjects, between the ALI and ARDS patients, or between the survival and the died patients ( all P gt;0. 05) . The level of VEGF-A in serumhad no correlation with lung injury score, A-aDO2 /PaO2 , PaO2 /FiO2 , or PaO2 ( all P gt;0. 05) . Conclusion The changes of VEGF-A in EBC of patients with ALI/ARDSmay serve as an indicator for severity and prognosis evaluation.
Objective To investigate the concentration of 8-isoprostaglandin ( 8-iso-PG) in exhaled breath condensate ( EBC) of patients with acute lung injury/acute respiratory distress syndrome ( ALI/ ARDS) , and evaluate its clinical significance. Methods Thirty-one ALI/ARDS patients who received mechanical ventilation were recruited as an experimental group, and EBC was collected with improved EcoScreen condenser, while thirty normal subjects were recruited as a control group. The 8-iso-PG level in EBC was analyzed by ELISA. The ALI/ARDS patients were subdivided into a continuous ALI group ( n=10) , a continuous ARDS group ( n=9) , a worsening group ( n=6) , and a remission group ( n=6) by state of illness on 1st day and 5th day. The 8-iso-PG level in EBC of the ALI/ARDS patients with different severity and different prognosis were compared, and the correlation were analyzed between the 8-iso-PG level and clinical indicators. Results The 8-iso-PG levels in EBC of the ALI/ARDS patients on 1st day and 5th day were higher than those in the control subjects respectively [ ( 45.53 ±14.37) ng/L and ( 45.31 ±12.42) ng/L vs. ( 19.47 ±4.06) ng/L, Plt;0.001] . The 8-iso-PG level was higher in the worsening group than the remission group, higher in the continuous ARDS group than the continuous ALI group, and higher in the nonsurvival group than the survival group ( Plt;0.05) . The 8-iso-PG level in EBC was positively correlated with white blood cell count in peripheral blood, lung injury score, X-ray score, AaDO2 /PaO2 , AaDO2 , VT , VE and MEWS score, and negatively correlated with PaO2 /PAO2 and PaO2 /FiO2 . Conclusion The 8-iso-PG level in EBC of ALI/ARDS patients has reference value for judging severity and prognosis of ALI/ARDS.
Objective To investigate the short-term postoperative pain between robot-assisted and thoracolaparoscopic McKeown esophagectomy for esophageal carcinoma. Methods We prospectively analyzed clinical data of 77 patients with esophageal carcinoma in our hospital between September 2016 and February 2017. The patients were allocated into two groups including a robot group and a thoracolaparoscopic group. The patients underwent robot assisted McKeown esophagectomy in the robot group and thoracolaparoscopic McKeown esophagectomy in the thoracolaparoscopic group. There were 38 patients with 30 males and 8 females at average age of 60.80±6.20 years in the thoracolaparoscopic group, and 39 patients with 35 males and 4 females at average age of 60.90±7.20 years in the robot group. Results There was no statistical difference between the two groups in terms of the postoperative usage of analgesic drugs. The patients in the robot group experienced less postoperative pain on postoperative day 1, 3, 5, 6 and 7 than the patients in the thoracolaparoscopic group. The mean value of visual analogue scale (VAS) on postoperative day 1, 3, 5, 6 and 7 for the robot group and the thoracolaparoscopic group was 3.20±1.10 versus 2.70±0.90 (P=0.002), 2.75±0.96 versus 2.40±0.98 (P=0.030), 2.68±1.08 versus 2.02±0.8 (P=0.005); 2.49±0.99 versus 1.81±0.88 (P=0.003), 2.27±0.83 versus 1.51±0.61 (P<0.001), respectively. Conclusion Compared with the thoracolaparoscopic group, patients receiving robot assisted McKeown esophagectomy experience less postoperative short-term pain. However, the long-term postoperative pain for these patients needs to be further studied.
