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.

BACKROUND:Corneal hemangiogenesis occurs in 40%-60%patients after keratoplasty.Blood vessel is one of the high risk factors for corneal immunological rejection.To inhibit corneal hemangiogenesis would prolong the survival time of the grafts and promote the successful rate of the keratoplasty.OBJECTIVE:To explore the inhibitive effects of doxycycline on corneal angiogenesis after keratoplasty.DESIGN,TIME AND SETTING:A randomized controlled animal experiment was performed at the State Key Laboratory of Ophthalmology(No.2006DA105054),Zhongshan Ophthalmic Center,Sun Yat-sen University from March to August 2007.MATERIALS:A total of 48 healthy dean Sprague Dawley rats served as recipients(right eye)and 24 Wistar rats as donors(both eyes).CD31-PEfluorescent antibody was obtained from Sigma,USA.Sandwich enzyme-linked immunosorbent assay(ELISA)kit for vascular endothelial growth factor(VEGF)was brought from RapidBio,USA.METHODS:Corneal allogenic transplantation models were established in rats.Recipients were equally and randomly divided into 2 groups:saline control group and doxycycline group.Twenty minutes prior to surgery,mydriasis was performed using 1%atropine,with a diameter of 2.75 mm of implant and 2.5 mm of implant bed.In the saline control group,conjunctiva of the right eye received saline,three times a day,following surgery.In the doxycycline group,conjunctiva of the right eye received 1%doxycycline,three times a day,till 30 days following surgery.MAIN OUTCOME MEASURES:The following parameters were measured:corneal angiogenesis using immunofluorescence,expression of VEGF protein by using ELISA.RESULTS:Compared with the survival time of saline control group[(9.67±2.73)days],the mean survival time of doxycycline group[(20.67±3.01)days]was significantly prolonged(P＜0.01).The mean percentages of neovascularized corneal area in the saline control group were(4.00±1.00)%,(14.33±4.04)%,(31.33±3.51)%at 3,7 and 14 days after keratoplasty,respectively.The mean percentages of neovascularized corneal area in the doxycycline group were(1.67±1.15)%,(4.67±1.53)%,(18.33±1.53)%at the same time point respectively.Compared with the saline control group,the mean percentages of neovascularized corneal area of the doxycycline group was significantly reduced at 7 and 14 days after keratoplasty(P ＜0.05).The expression of VEGF in the saline control group was(541.00±75.44)pg/mg,(960.00±90.14)pg/mg,(976.00±130.41)pg/mg at 3,7 and 14 days after keratoplasty,respectively,while expression of VEGF in the doxycycline group was(115.33±9.29)pg/mg,(239.00±41.62)pg/mg,(361.00±65.20)pg/mg,respectively.The difference of VEGF expression at all time points between the two groups was significant (P＜0.05).CONCLUSION:Doxycycline has a significant effect in inhibiting corneal angiogenesis and prolonging survival time of implants after keratoplasty.

BACKGROUND: Cervical lymph nodes are draining region of cornea. It is believed that aqueous fluid goes through a minor pathway named uveoscleral drainage, which will allow passage of antigen-presenting cells (APC) directly to the draining lymph nodes and induce allograft rejection after keratoplasty.OBJECTIVE: To explore the inhibitory effects of cervical lymphadenectomy in alkali induced high-risk corneal transplantation.DESIGN: A randomized controlled animal experiment.SETTING: State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University.MATERIALS: The experiment was performed in the State Key Laboratory of Ophthalmology (No. 2006DA105054), Zhongshan Ophthalmic Center, Sun Yat-sen University from May 2005 to February 2007. 144 male animals (1-2 months old) including 104 SD rats and 40 Wistar rats were provided by the animal experimental center of Sun Yat-sen University. Sandwich enzyme-linked immunosorbent assay (ELISA) kits for interleukin-2 (IL-2) and interferon-γ (IFN-γ) were brought from BioSource International company (USA). The animal treatment in the experiment was accorded with the statement in Association for Research in Vision and Ophthalmology (ARVO) for animals.METHODS: With the SD rats as recipients, and Wistar rats as donors, all rats were subjected to corneal allografting. The recipient rats were randomly divided into 4 groups (n=20): group A (control group) which underwent corneal transplantation; group B which was subjected to bilateral cervical lymphadenectomy; group C, corneal transplantation 21 days after the alkali burn injury; group D, cervical lymphadenectomy following group C. The immune rejection of grafts was evaluated by detecting the expression of IFN-γ and IL-2 using ELISA. The time when allograft rejection occurred was recorded and mean survival time (MST) was compared among the groups. The development of corneal inflammation and new vessels was examined by slit lamp microscope and histopathological examination.MAIN OUTCOME MEASURES: ①The development of corneal inflammation after corneal alkaline burns. ②MST of rats in each group following transplant. ③The expression of IL-2 and IFN-γ in grafts of each group. RESULTS: ①Normal rat cornea was transparent without inflammation or neovascularization. There were many inflammatory cells invading to stroma on day 3 after burn. Then, the inflammation of cornea resolved gradually 3 weeks after the burn, but corneal neovascularization reached the peak at that time. Corneal blood vessels regressed completely at the end of 8 weeks after the burn. ②The MST of group A, B, C, and D was (10.40±1.14), (46.30±9.46), (7.00±1.58), and (15.00±3.39) days, respectively. Compared with the group A, the MST of group B was significantly longer (P < 0.05), and the MST of grafts in group D was also significantly longer than group C (P < 0.05). ③The expression of IFN-γ and IL-2 proteins was absent in group B. Compared with group C, the expression of IL-2 and IFN-γ proteins in group D significantly decreased on days 3, 7, 10, and 14 after keratoplasty (P < 0.05). CONCLUSION: Cervical lymphadenectomy therapy can effectively inhibit corneal allograft rejection in normal and high-risk corneal beds after alkali burn injury.
