RESUMO

Objective To investigate the impact of perioperative mild hypothermia on the neurological function and prog-nosis of patients with acute type A aortic dissection. Methods This study enrolled 65 patients with acute aortic dissection un-derwent surgery during the period of February 2017 to February 2018 and randomly divided them into mild hypothermia group and control group. After the process of deep hypothermic circulatory arrest,patients in the mild hypothermia group were re-warmed to 34 ℃ - 35 ℃ and maintained until 24 h after the operation. While,the patients in the control group were rewarmed to 36 ℃ and were treated with routine rewarm therapy. Baseline characteristics were recorded before the operation and neuro-logical and prognosis related indexes were recorded after the operation for all the patients. At the same time,peripheral venous bloods of all the patients were collected preoperatively and at 1、6、 12 and 24 h after the operation. Serum S 100β and neuron-specific enolase(NSE)levels were measured by ELISA kit. Results Compared with the control group,patients in the mild hypothermia group had a significantly shorter recovery time[ 10. 6 h(IQR:7. 6, 19. 1)vs. 25. 8 h(IQR: 13. 3,54. 2),P =0. 007]. At the same time,serum levels of NSE at 1 h and 6 h after operation and serum levels of S 100β levels at 1、6、 12 and 24 h after operation in the mild hypothermia group were significantly lower than those in the control group(P < 0. 05). In addi-tion,the length of stay in the mild hypothermia group was significantly shorter than that in the control group[ 19 days(IQR: 17, 23)vs. 24 days(IQR: 17,28),P = 0. 036]. However,there was no statistically difference in the incidence of delirium and cerebrovascular accidents between the two groups. Conclusion Perioperative mild hypothermia therapy can significantly re-duce brain cell damage in the patients with acute type A aortic dissection and can shorten postoperative recovery time and hospi-talization time,and thus improve the prognosis of patients.

RESUMO

BACKGROUND: Many data demonstrate that the components of soybean can lower blood lipid,suppress the growth of cancer cells and exert weak estrogenic activities. However,little is known about the effect of isolated soybean protein on the lifespan of the organism.OBJECTIVE: To observe the effect of isolated soybean protein on the lifespan of drosophila melanogasters and investigate the mechanism of effective anti-aging and anti-oxidation action.DESIGN: A controlled trial based on drosophila melanogasters.SETTING: Department of nutrition and food hygiene in a university.MATERIALS: The experiment was conducted in the Department of Nutrition and Food Hygiene,Public Health College of Xinjiang Medical University from March to June 2002. A total of 400 drosophila melanogasters of American wild type with half for each gender were provided by the Department of Nutrition and Food Hygiene, Public Health College of Xinjiang Medical University.METHODS: The 400 drosophila melanogasters were divided into control group(normal culture) and three-dosage experiment groups(normal culture contained isolated soybean protein 0.2%,1.0% and 5.0%,respectively).From the second day on, the number of living and dead drosophila melanogasters was observed and counted until all died. Meanwhile, mean lifespan,half death time and maximal lifespan were calculated.MAIN OUTCOME MEASURFS: Mean lifespan, half death time and maximal lifespan of the drosophila melanogasters.RESULTS: Compared with that of control group, the lifespan of male and female drosophila melanogasters in experiment groups was prolonged by isolated soybean protein and responded in a dose-dependent manner,especially in high-dosage group. The mean lifespan, half death time and maximal lifespan of both female and male drosophila melanogasters were prolonged by 24.5% and20.7%,27.1% and22.0%,and 13.9% and 10.6%,respectively.CONCLUSION: Isolated soybean protein may have anti-aging and lifespan-prolonging effects on drosophila melanogasters.
