Objective To discuss the liver function recovery affected by the portal vein flow in patients who underwent adult-to-adult living donor liver transplantation using the right lobe. Methods Seventy-four donors and recipients were included in this study. Intraoperative Doppler ultrasound (IOUS)were performed before splitting the donor liver and 1 hour after the graft reperfusion. The diameter and velocity of portal vein were measured and recorded for calculation of portal vein flow(PVF). Liver function tests were undertaken at the day 2nd,7th, 15th and 30th postoperative,respectively. Results One hour after reperfusion of 74 grafts,the PVF were significantly increased (2. 84 ± 0. 93) fold. Seventy-four grafts were divided into 4 groups according to the different degrees of the increase of PVF. The levels of blood bilirubin total(TBIL) among 4 groups were differently at the day 2nd,7th, 15th and 30th postoperative. High PVF contributed to recipient's prolonged hyperbilirubinemia ( P <0. 001 ). The levels of ALT, AST among 4 groups were differently at the day 7th, 15th and 30th postoperative( P <0. 001). Conclusions Detection of portal vein hemodynamics in living donor liver transplantation by IOUS may assist surgeon to anticipate the graft's function and take surgical therapies to secure the graft and the recipient.

Objective To observe the developmental changes of projection and termination of proprioceptive afferent fibers in the mouse spinal cord. Methods Parvalbumin (PV) immunohistochemistry was used to label the proprioceptive afferents. Single and dual immunofluorescence histochemistry were used to examine the growth pattern of proprioceptive afferents and their relationships with motoneurons in the spinal ventral horn (VH). The stained sections were observed under a confocal laserscanning microscope. Results PV-like immunoreactive (LI) proprioceptive fibers first appeared in the dorsal column on embryonic (E) day 14, then entered the gray matter on El5 and reached the intermediate gray matter and VH more obviously on E16. The number and intensity of PV-LI proprioceptive afferent fibers and punctata increased in the VH with age and reached a maximum during earlier postnatal (P) period (P0-P7). After P14, the number and intensity of proprioceptive afferents gradually decreased. The proprioceptive terminals seemed to form close relationship with motoneurons from E17. Conclusion The present study indicates that the somatotopic organization of proprioceptive afferents in the spinal cord is established during the late embryonic and early postnatal stages. These results provide evidence for understanding the development of the reflex movements.

The present study was designed to examine the developmental changes in projection and termination of nociceptive and proprioceptive afferent fibers in the spinal cord by labeling those two fibers with calcitonion gene-related peptide (CGRP) and parvalbumin (PV)separately in mouse embryos and neonatal pups aged embryonic day 15 to posanatal day 3 (E15 -P3). CGRP-like immunoreactive (LI)nociceptive fibers first appeared in the superficial dorsal horn (DH) at E16. The afferent projections extended laterally to the DH and entered into the deep portions of the DH at E17 and E18. After birth, the projection pattern of CGRP-LI fibers remained unchanged but the intensity of afferent terminals increased in the superficial laminae and their branching patterns became more complicated. In addition,CGRP-LI collaterals that projected into the contralateral DH were also examined after E16. Around birth, the contralateral projections were also found originated from the lateral part of the DH. PV-LI proprioceptive afferents were first observed entering the gray matter at E15 and reached the intermediate gray matter (IG) and the ventral horn (VH) more obviously on E16. The number and intensity of PV-LI fibers increased in the the VH with age and reached a maximum during earlier postnatal period ( P0-P3 ). The proprioceptive terminals seemed to form close relationship with motoneurons in the VH from E17. Our results indicate that the somatotopic organization of nociceptive and proprioceptive afferents in the spinal cord both are established during the late embryonic and early postnatal stages. These results help to understand the development of the sensory transmission in more details.
