Objective To explore the value of MRI in the diagnosis of fetal aortic arch anomalies. Methods We retrospectively collected 10 fetuses with aortic arch anomalies indicated by prenatal ultrasound and underwent MR examination and were subsequently proven by autopsy or post-birth follow-up from 320 pregnant women. We focused on the observations of the location of the aortic arch and brachiocephalic artery anomalies, the locations of the liver and stomach in the abdominal cavity, and the large vessels in abdomen. The above-mentioned finding were compared with prenatal ultrasound and follow-up findings. Results Of 10 cases, right aortic arch with aberrant left subclavian artery was seen in 7 cases, right aortic arch with the mirror branch, left aortic arch with aberrant right subclavian artery, right aortic arch with aberrant left subclavian artery combined with cervical aortic arch and double aortic arch was seen in 1 case, respectively. All aortic arch anomalies detected by MRI were consistent with post-birth or autopsy findings. Ultrasound misdiagnosed aortic branch malformation in 5 places, which included right aortic arch but misdiagnosed aberrant left subclavian artery in 2 cases, right aortic arch never diagnosed mirror branch anomaly in 1 case, right aortic arch with left subclavian artery misdiagnosed cervical aortic arch in 1 case, left atrial isomerism but misdiagnosed left aortic arch with aberrant right subclavian artery in 1 case;One double aortic arch was misdiagnosed as right aortic arch with aberrant left subclavian artery in ultrasound. Conclusion Fetal cardiovascular MRI is an effective and supplementary examination to complement ultrasound in diagnosis of fetal aortic arch anomalies.

Objective: To summarize the postoperative nursing experience of 1 patient with pancreatic cancer who underwent pancreaticoduodenectomy combined with superior mesenteric vein resection and artificial vascular reconstruction. Methods: The nursing measures included: paying attention to anticoagulation treatment and observing its effect, strengthening pain management, giving nutritional support, pertinent nursing care for gastroparesis, guiding quantitative respiratory treatment for patient, preventing the lack of trace elements during jejunitas. Results: Through active and effective nursing, the patients were discharged smoothly forty-seven days after operation. Conclusions Through nursing of 1 patient with pancreatic cancer underwent pancreatoduodenectomy combined with superior mesenteric vein resection and artificial vascular reconstruction after surgery, nurses can improve the nursing skills and nursing observation ability, as well as the theoretical basis and practical experience for the future clinical work.

Objective To investigate the effects of different target blood glucose control on postoperative complications during fasting after abdominal surgery by Meta-analysis. Methods From January 1990 to May 2016 the computer retrieval of related Chinese and foreign literature into surgery during the fasting blood glucose control in different range of patients, were randomly divided into control group and intervention group, from two independent data extraction and document evaluation. Meta-analysis using RevMan5.3 software. Results A total of 6 articles were included. Meta-analysis results showed that after abdominal surgery during the fasting of different target blood glucose control on the incidence of hypoglycemia, the incidence of postoperative complications of surgical incision infection after operation, the differences were statistically significant (P<0.05), However, there was no significant difference in postoperative mortality rate (P>0.05). Conclusions After abdominal surgery in patients with intensive glycemic control during the fasting ,value at the lower range (4.4-6.1mmol/L) can effectively reduce the incision infection and the incidence of postoperative complications, is conducive to the rehabilitation of patients, but increase the risk of hypoglycemia, and it has little effect on the mortality of patients during hospitalization. The control group included blood glucose range is too large or lack of continuity and included in the study Chinese literature is too small, leads to a limitation of the research, the analysis results still need more clinical nursing practice and a large number of high quality documents to support.

【Objective】 To study the effect of air inlet modes on the temperature variation, fluctuation, uniformity and coefficient of variation(CV), so as to evaluate the stability and uniformity of the temperature field in refrigerated warehouse for blood. 【Methods】 The temperature changes of blood refrigerated warehouse under different modes of air inlet during compressor operation were analyzed. The stability of the temperature field in the storehouse was evaluated by the changes, fluctuation, uniformity, CV and deviation of temperature at each testing point. 【Results】 The average value of temperature in the storehouse, adopting air inlet via straight blow, was (4.98±0.92)℃, while that of air inlet via micro-hole mode was(4.15±0.25)℃, with significant differences between each other(P<0.05). As to the CV of temperature, air inlet via straight blow was significantly different from that via micro hole(P<0.01). The fluctuation, uniformity and deviation of temperature created by straight blow and micro hole were 1.85±1.11 vs 0.49±0.38, 1.00±0.68 vs 0.47±0.37, and 0.61±0.45 vs 0.27±0.21, respectively, with significant differences between each other(P<0.01). 【Conclusion】 Compared with straight blow, the mean temperature created by micro hole was closer to the median value (4℃) of the temperature range, i. e.(4±2)℃, during blood storage. Otherwise, micro hole demonstrated a smaller CV of temperature, and superior performance in fluctuation, uniformity and deviation of the temperature at the testing points, which was conducive to ensure the stability of storehouse temperature field.
