ObjectiveTo analyze the characteristics of severe trauma patients with acute kidney injury (AKI) receiving renal replacement therapy (RRT), in order to look for the risk factors of AKI and the opportune time for the initiation of RRT on prognosis.Methods A retrospective cohort study involving consecutive patients with severe trauma in emergency intensive care unit (ICU) in the Second Affiliated Hospital of Zhejiang University School of Medicine, from August 2011 to December 2014, was conducted. Inclusion criteria included age≥18 years, injury severity score (ISS)> 16, AKI receiving RRT, and the duration of hospital stay> 24 hours. The general data, the risk factors of AKI, the prognostic indicators, and the information of RRT were recorded. All patients were divided into two groups according to the prognosis, the time of onset of AKI and the initiation time of RRT. The independent risk factors for prognosis were screened by binary logistic regression analysis.Results Seventy-three patients were eligible for enrollment, including 48 deaths (65.8%); 49 patients suffered from AKI≤48 hours after trauma (early stage group), and in 24 patients it was longer than 48 hours (late stage group). In 55 patients RRT was routinely started (routine RRT group), 18 patients underwent RRT ahead of routine criteria decided by the judgment of the attending doctor (earlier RRT group). The main risk factors of RRT in traumatic patients with AKI were shock and sepsis, each accounted for 90.4% and 53.4%. Compared with survival group, in death group, the proportion of male patients was lower (70.8% vs. 100.0%,χ2 = 7.238,P = 0.007), acute physiology and chronic health evaluationⅡ (APACHEⅡ) scores were higher (23.7±5.1 vs. 14.4±3.7,t = 8.031,P< 0.001), Glasgow coma score (GCS) was lower [5.0 (3.0, 15.0) vs. 15.0 (8.0, 15.0),U = 320.000,P = 0.001], incidence of shock and sepsis was higher (97.9% vs. 76.0%,χ2 =6.755,P = 0.009; 64.6% vs. 32.0%,χ2 = 7.014,P = 0.008), the rate of use of contrast medium was lower (27.1% vs. 56.0%,χ2 = 5.898,P = 0.015), the time for the diagnosis of AKI post trauma was delayed [days: 2 (1, 5) vs. 2 (1, 2), U = 762.000,P = 0.049], the time for the initiation of RRT post trauma was later [days: 6.0 (3.0, 12.0) vs. 3.0 (2.0, 4.5), U = 868.500,P = 0.002], the recovery rate of renal function at discharge was lower (10.4% vs. 100.0%,χ2 = 54.497, P< 0.001). Compared with late stage group, in early stage group, the mortality was lower (55.1% vs. 87.5%,χ2 =7.509,P = 0.006), and the incidence of sepsis before AKI was also lower (38.8% vs. 83.3%,χ2 = 12.854,P< 0.001). Compared with routine RRT group, the recovery of renal function at discharge was better with a lower mortality rate in the earlier RRT group, but the difference was considered to be insignificant (55.6% vs. 36.4%,χ2 = 2.064,P = 0.151;50.0% vs. 70.9%,χ2 = 2.633,P = 0.105). Logistic regression analysis showed GCS [odds ratio (OR) = 0.852, 95%confidence interval (95%CI) = 0.747-0.972,P = 0.017], shock before AKI (OR = 85.350, 95%CI = 5.682-1 282.073, P = 0.001), and sepsis before AKI (OR = 11.499, 95%CI = 2.127 - 62.161,P = 0.005) were independent risk factors for the judgment of prognosis.Conclusions Shock and sepsis are the major risk factors of RRT in trauma patients with AKI. Shock, sepsis and traumatic brain injury are the independent risk factors of death. Perhaps early initiation of routine RRT cannot improve the outcome of the patients with posttraumatic renal insuficiency.

Objective To investigate the effects of post-propofol anesthesia on cognitive function and hippocampus proteome expressions in aged rats.Methods Thirty healthy male Wistar rats aged 20 months were randomly divided into control group(n =15) and propofol group(n =15).The control group was injected with normal saline of 6 ml/kg intraperitoneally and propofol was injected intraperitoneally with propofol 60 mg/kg.The rats in both groups underwent Step-down Test to assess cognitive function at the first day and at the seventh day after the termination of drug administration.Five rats were decapitated randomly each time after the two step-down tests and their hippocampi were removed for two-dimensional gel electrophoresis and mass spectrometric analysis.Results In the step-down test,aged rats in the propofol group showed significantly learning impairment and decreased memory abilities at the 1st day after propofol anesthesia as compared with those in the control group.In learning phase of the 1st day,the latency of the propofol group is (29.5 ± 7.6)s as compared with(19.7 ± 7.0)s of the control group,while the error time is 3.6±1.2 vs.1.6 ±0.8 in the propofol group vs the control group,and the total time of electric shock is(65.2 t 10.6)s vs.(42.7 ± 10.3)s in the propofol group vs the control group(all P＜0.01).The latency of the memory phase in the propofol group is also decreased as compared with that in the control group(31.4±14.3)s vs.(111.2± 23.7) s,(P＜0.01).On the 7th day after anesthesia,there was no significant difference between the two groups.There were 17 differentially expressed proteins on the 1st day after propofol anesthesia,6 of them were up-regulated and 11 proteins were down-regulated (P ＜ 0.05).On the 7th day,there were 10 differentially expressed proteins,and the expression of 5 proteins was down-regulated (P ＜ 0.01).Conclusions Aging rats receiving propofol anesthesia show cognitive function decline,but do not show a long-term decline.The mechanism may be related to the different expressions of hippocampal proteins.

Objective:To observe the growth and development of the weaned mice fed with different levels of dietary zinc and to explore the expression of zinc transporter 3(ZnT3) mRNA induced by different dietary zinc intakes. Methods: Twenty male weaned mice (postnatal day 21) were divided into 4 groups: zinc deficient (ZD), zinc adequate(ZA), zinc supplemental (ZS) and pair fed(PF). Mice were fed with different levels of dietary zinc for 3 weeks (from postnatal day 21 to postnatal day 42) ;the zinc contents of ZD, ZA, ZS and PF group were 1 mg/kg, 30 mg/kg, 180 mg/kg and 180 mg/kg respectively. From postnatal day 21 to postnatal day 42, the diet intakes and weight of the mice were measured everyday. On postnatal day 42, the mice were sacrificed and tissues were immediately isolated and frozen lor RNA extraction. The serum zinc concentrations were measured by AAS and the expression of ZnT3 mRNA was determined by semiquantitative RT-PCR. Results: The dietary intakes and weight of ZD mice were much lower than that of other groups(P3

Objective To clarify the effects of exercise- and food intake restriction-induced weight reduction on expression of ghrelin in plasma and stomach of obese rats,and to explore the role of ghrelin during weight loss. Methods 100 weaned Sprague-Dawley(SD) rats were randomly divided into control group(fed with standard chow,n= 20) and model group (two-bottle-feeding method,fed with standard chow and high-fat diet simultaneously, n=80). After 20 weeks feeding, Lee' s index of control was used as the reference of diet-induced obesity identification, and then diet-induced obese rats were randomly divided into four groups:obese control group,swimming group,food intake restriction group and swimming+food intake restriction group, eight rats in each group. Rats in swimming group underwent long-term(40 min,6 days/week for 5 weeks)swimming exercise. Calorie in food intake restriction group was restricted 1/3 of normal kcal for 3 weeks,and subsequently restricted 1/3 for 2 weeks. Swimming+food restriction group had the same intervention as swimming and food restriction group. 8 normal diet rats were also chosen as controls. After five weeks of treatments,peripheral fat mass of testis and kidney,ghrelin proteins in plasma and stomach,and ghrelin mRNA in stomach were measured. Results Gastric ghrelin protein and mRNA were significantly lower in obese control group than those in normal control group (P<0.05). However, plasma ghrelin did not decrease markedly in obese control rats(P>0.05). Compared with obese control group,weight and fat mass in all weight loss groups declined notablely(P<0.05);in swimming and swimming+food restriction groups,the expression of ghrelin protein or mRNA in plasma or stomach increased remarkably( P<0.05); in food restriction group, the level of ghrelin mRNA raised significantly (P<0.05), while ghrelin protein in plasma and stomach had not change. Conclusion The level of ghrelin increased in exercise induced weight loss,while showed no significant change in food intake restriction group, suggested that ghrelin might be involved in the process of weight loss induced by exercise.
