OBJECTIVETo analyze risk factors of marginal donors in living donor liver transplantation.

METHODS98 living donor liver transplantation (LDLT) patients over the 7-year period from 2001 to 2007 in our transplantation center were retrospected. Potential risk factors, including donor age, gender-mismatch, steatotic donors and graft-recipient weight ratio (GRWR), and their relationship with 6-month patient survival rate were analyzed.

RESULTSThe 4 patients received livers with more than 30% steatosis died within 6 months, and 6-month survival rate was 91.7% in patients received livers with less than 30% steatosis. The 6-month survival rate was 86.9% and 87.8% in patients with grafts of GRWR more than 0.8% and in patients with graft of GRWR less than 0.8%, respectvely (x2=0.022, P more than 0.05), however, middle hepatic vein reconstruction significantly affected the survival rate of small-size-liver recipients (x2=10.612, P less than 0.01). Donor age and gender-mismatch were not associated with the survival rate of recipients (P more than 0.05).

CONCLUSIONSSteatosis is an important risk factor in living donor liver transplantation. Lower GRWR is not a limitation but we must reconsider its importance in liver transplantation. The donor age and gender-mismatch are not associated with the survival rate of recipients.

BACKGROUND: Single tooth loss at posterior mandibular area is difficult to complete regularly axial implantation under limited conditions. Concerning this problem, some scholars employ the skill of tilted implantation with abutment angulations to restore it. However, the security study of this design has been limited until now. OBJECTIVE: To provide theoretical evidence for tilted implantation in the posterior mandibular area, and to make a biomechanical analysis on bone-implant interface after titled implantation under the same dynamic force stress. METHODS: First, restoration models of implant crown at different tilting angles in posterior mandibular area were built and optimized using the software CBCT and DICOM. Then dynamic force stress was applied in chewing cycles of the crown model. Finally, the stress-strain analysis of bone-implant interface was made by utilizing the three-dimensional finite element software Ansys. RESULTS AND CONCLUSION: (1) When the dental implant in the axis implantation was tilted to the lingual side at 5° or 10°, the maximum stress and strain values at the bone interface were 53.8 MPa and 2 671, respectively, under three loading conditions: the force during the chewing cycle was given vertical to the implant, toward the lingual side from the buccal side at 45° with the long axis of the tooth, and toward the buccal side from the lingual side at 45° with the long axis of the tooth. (2) When the implant inclined to the lingual side at a 15° angle, the rear edge of the implant was close to the interface between the cortical and cancellous bone, and the stress and strain values were bigger than those at any other implantation angle. (3) When the implant inclined to the lingual side at a 20° angle, the rear edge of the implant was beyond the interface between the cortical and cancellous bone, and contacted with the cortical bone that provided a support for the rear part of the implant. The stress and strain values on the bone interface were both reduced. The stress was concentrated in the cortex around the neck of the implant, and reduced a lot in the cancellous bone. The maximum strain value appeared at the contact site between the bone interface and the implant neck or rear part. It is concluded that in posterior mandibular area, the dental implant can be implanted at a < 10° linguoclination angle.

OBJECTIVETo detect the changes in intestinal mucosal permeation in rats with methotrexate-induced small intestinal damage and investigate the protective effects of Changyanqing decoction.

METHODSRat enteritis model was established by methotrexate (MTX) and sodium chloride. The rats were randomly divided into normal control group, model group, N-acetylcysteine (NAC) group and Changyanqing decoction group, and Changyanqing decoction (100 mg/kg) or saline was administered daily in the corresponding groups by gastric irrigation for 6 days. The disease activity index (DAI), colonic mucosal damage index (CMDI) and histological score (HS) of the rats were observed and evaluated. The levels of mRNA expressions of TNF-alpha and IL-1beta were detected by semi-quantitative RT-PCR. The expression of IL-10 was detected by enzyme linked immunosorbent assay, and IkappaB expression was determined with Western blotting.

RESULTSCompared with the normal control group, the model group showed significantly increased DAI, CMDI and HS. The DAI, CMDI, and HS in rats treated with Changyanqing decoction were significantly decreased in comparison with those in the model group (P<0.01). The expressions of TNF-alpha and IL-1beta were significantly higher in MTX-treated group than in the control group. The expression of TNF-alpha and IL-1beta mRNA in the Changyanqing group and NAC group were significantly lower, but IL-10 significantly higher than those of the MTX group. In MTX group, obvious NF-kappaB activation was observed, whose expression was significantly stronger in the cell nuclei, and the IkappaB in the cytoplasm was markedly degraded.

CONCLUSIONChangyanqing decoction offers protection on intestinal mucosa by inhibiting NF-kappaB activation to reduce TNF-alpha and IL-1beta mRNA expressions and increase IL-10 expression.
