ABSTRACT

Objective To evaluate the clinical outcome of kidney transplantation from donation after brain death (DBD) donors complicated with acute kidney injury (AKI). Methods Clinical data of 216 DBD donors were retrospectively analyzed, and they were divided into the AKI group (n=69) and control group (n=147) according to the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. Donors in the AKI group were further divided into the KDIGO stage 1 and stage 2-3 subgroups. One hundred and thirty-five recipients were assigned into the AKI group and 288 recipients in the control group. Postoperative recovery of renal function and clinical outcomes of the recipients were recorded. The risk factors of delayed graft function (DGF) were identified. Results The highest serum creatinine (Scr) level, Scr level before procurement, the highest blood sodium level and blood sodium level before procurement in the AKI group were higher than those in the control group. The application duration of vasopressors in the AKI group was longer than that in the control group. In the AKI group, the amount of fluid resuscitation within 48 h was higher, the HCO3− level at admission was lower, and the incidence of diabetes insipidus and hypotension was higher than those in the control group. The highest Scr level and the Scr level before procurement in KDIGO stage 2-3 donors were significantly higher than those in KDIGO stage 1 counterparts (all P<0.05). Compared with the control group, the incidence of DGF and acute rejection was higher, the proportion of continuous renal replacement therapy was higher, the Scr level within postoperative 90 d was higher, and the urine amount within postoperative 3 d was less than those of recipients in the AKI group. Compared with KDIGO stage 1 recipients, KDIGO stage 2-3 recipients had higher Scr levels at postoperative 3, 4, 5 and 15 d, and less urine amount at postoperative 2 d (all P<0.05). Univariate analysis showed that donor age, the highest Scr level, the highest blood sodium level and the amount of fluid resuscitation within 48 h were the risk factors for DGF in recipients after kidney transplantation. Multivariate analysis showed that donor age was the independent risk factor for DGF in recipients after kidney transplantation (all P<0.05). Conclusions For the application of DBD donors complicated with AKI, active organ maintenance should be performed to alleviate AKI. It exerts no effect upon graft function and survival rate at postoperative 6 months, which may achieve equivalent efficacy as non-AKI donors and may be used as a source of extended criteria donor kidneys.

ABSTRACT

Objective To investigate the effect of recombinant botulinum neurotoxin serotype A heavy chain (BoNT/A heavy chain)on local proteins which are related to nerve growth after spinal cord injury in rats,and to get some experimental evidence to explain the mechanism of BoNT/A heavy chain in stimulating neuritogenesis. Methods Recombinant botulinum neurotoxin serotype A heavy chain was applied locally or intrathecally to rats with ipsilateral semi-dissociated lumbar spinal injury. Local spinal tissue was extracted for general protein expression by two dimension electrophoresis plus nitrate silver staining after different time period of injury. Based on the results of 2-D gel electrophoresis,growth-associated protein 43(GAP-43)and of superior cervical ganglion 10(SCG 10)were selected to examine the changes of their expression and distribution features under BoNT/A heavy chain administration using SDS-PAGE,western blot and immunofluorescence. Results (1)The model of spinal cord injury(SCI)in this study was an ipsilateral semi-dissociated lumbar SCI in rat. The rats showed obvious motor and sensory dysfunction in the ipsilateral hind limb.(2)The results from 2-D gel electrophoresis plus nitrate silver staining showed that the administration of BoNT/A heavy chain based on SCI altered the local protein expression pattern. The decrease or increase in the expression of some protein dots /dots group was clearly seen after single SCI. However, these changes were transformed by BoNT/A heavy chain treatment,which appeared as a reversed pattern turning toward that in control group or further increased expression upon SCI,such as the dots located respectively at 35-45 kDa and 18-25 kDa level,pI between 5-7. In addition,the expression of the two dots located at the level as above increased after SCI only, and showed further increase in their expression with BoNT/A heavy chain intervention.(3)The changes of selective GAP-43 and SCG 10 expression and distribution by western blot and immunofluorescence indicated that the administration of BONT/A heavy chain based on SCI amplified the expression of GAP-43 and SCG 10(P < 0.05). Meanwhile,the positive immuonfluorescent staining for both GAP-43 and SCG 10 mainly distributed nearby the proximal area of injury, both cytoplasm and neuronal processes were positively stained. Conclusions Intrathecal delivery of BoNT/A heavy chain increases the expression of growth-associated proteins GAP 43 and SCG 10 after SCI in rats.

ABSTRACT

Objective@#To observe the effect of the expressive or functional blockage of TRPV1 on nerve regeneration after sciatic trans-section injury.@*Methods@#AMG-517, a kind of TRPV1 inhibitor, was injected into the surrounding area of the ipsilateral lumbar dorsal root ganglia while unilateral sciatic nerve was transected. A total of 24 healthy male Sprague-Dawley rats were divided into 4 groups: control group, injury only group, injury+ AMG-517 150 μg/kg group, injury+ AMG-517 300 μg/kg group. The injury only group was injected the same volume of medium. The release of CGRP from dorsal-horn of spinal cord, the number of axons at proximal stem of sciatic nerve after transection, and the expression of TRPV1 in dorsal root ganglion were detected using the methods of ELISA, Western blot and semi-thin section (1 μm)- toluidine blue staining 2 weeks after injury.@*Results@#The release of CGRP in lumbar spinal dorsal horn was obviously decreased after AMG-517 treatment, which was the evidence of TRPV1 functional inhibition. CGRP in the control group was 0.15 ng/g, the injury only group 0.17 ng/g, AMG-517 150 μg/kg group 0.09 ng/g, and AMG-517 300 μg/kg group 0.11 ng/g(P<0.01). The number of axons which were myelinated or unmyelinated increased after the TRPV1 was inhibited by AMG-517(P<0.01). In addition, the injection of AMG-517 into surrounding dorsal root ganglion decreased the expression of TRPV1 in dorsal root ganglion(P<0.01).@*Conclusions@#Over expression or activation of TRPV1 after periphery nerve injury has negative effect on nerve regeneration in fact; Inhibiting the over-expression or over-activation of TRPV1 after nerve injury facilitates axonal regeneration and nerve repair.

ABSTRACT

AIM:To observe the effect of botulinum neurotoxin type A heavy chain ( BoNT/A HC) on the pat-tern of spinal protein expression by intrathecal injection after spinal cord injury in rats , and to explore the role of BoNT/A HC intervention in spinal protein expression and some of its mechanisms in nerve regeneration after injury .METHODS:The model of unilateral lumbar spinal cord injury was established .The effects of BoNT/A HC intervention at different doses (2 μg, 4 μg, 6 μg and 8 μg) on the general pattern of protein expression in the spinal cord tissues at the injury site and the cranial part adjacent to the injury site was measured and evaluated by SDS-PAGE and Coomassie brilliant blue staining first, and then by two-dimensional SDS-PAGE.RESULTS:The histological structure of the ipsilateral side of lumbar spi-nal cord showed obvious destruction and degradation , mainly affecting both gray and white matter of the left side of the cord.The result of SDS-PAGE with Coomassie brilliant blue staining from injured spinal cord tissue displayed that the ex-pression of some proteins after one-time BoNT/A HC treatment appeared obviously different from that without BoNT /A HC treatment.Moreover, the pattern of the protein expression affected by BoNT/A HC was similar to that of the normal spinal cord.The more detail information from two-dimensional SDS-PAGE indicated that more than 10 proteins with different mo-lecular weight and isoelectronic points were differentially expressed at day 2 and day 20 after local injection of 6μg BoNT/A HC.This altered expression actually appeared a tendency toward the pattern shown in normal group .CONCLUSION:The immediate application of BoNT/A HC at the injury site after unilateral lumbar spinal cord injury is able to affect the pattern of local protein expression .The altered protein expression by injury could be reversed back to normal or approxi -mately normal by local BoNT/A HC administration.
