Objective To evaluate the treatment and prevention measure for intrahepatie diffuse biliary stricture after orthotopic liver transplantation. Methods The clinical data of 21 patients with intrahepatic diffuse biliary stricture after orthotopic liver transplantation from January 2002 to December 2007 in Beijing Center for Organ Transplantation were retrospectively analyzed. A prospective clinic study was launched in order to prevent microthrombosis in the microcireulation of bile duct during warm and cold iscbemia in non-heart-beating donor since January 2006. Urokinase perfusion of the artery system was conducted during graft harvesting and reperfusion at the end of graft trimming to reduce the incidence of intrahepatic diffuse biliary stricture. Results Among 21 patients with intrahepatie diffuse and mixed type biliary stricture, 16 patients underwent liver retransplantation, and the other 5 patients died of primary graft failure while waiting for retransplantation. The incidence of intrahepatic diffuse biiiary stricture was 5.9% in non-urokinase perfusion group. On the contrary, the incidence rate of intrahepatie diffuse biliary stricture was 1.4% in urokinase perfusian group (x2 = 5.98, P < 0. 05). Conclusions Liver retransplantation is effective for refractory biliary stricture in liver transplant recipients. The incidence of intrahepatic diffuse biliary stricture is reduced in non-heart-beating donor by using urokinase perfusian.

[Objective]To evaluate the feasibility of repairing cartilage defect with tissue-engineered cartilage ,which was made of chondrocytes and osteoblast seeded onto a biodegradable porous bioceramic ?-tricalcium phosphate (?-TCP).[Method] A porous bioceramic template of ?-TCP was created in the shape of a circular cylinder. Chondrocytes and osteoblasts induced from dog bone marrow stem cells were seeded onto the ?-TCP and then kept them growing together for 1 week prior to transplantation into the cartilage defects. After 12 , 16 weeks ,the specimens were harvested and examined macroscopically, histologically and immunohistochemically. [Result] Gross morphological and histological analysis of the specimens from the ?-TCP complex demonstrated new cartilage construction. The result was better than that in control group. [Conclusion] These findings suggest that porous bioceramic (?-TCP) is a good "matrix" for chondrocytes and osteoblasts, and can be used for cartilage engineering.

Objective To summarize the experience of emergency orthotopic liver transplantation (EOLT) in fulminant hepatic failure (FHF).Methods The clinical date of 4 cases of FHF successfully subject to EOLT were retrospectively analyzed.Results Four patients’ consciousness completely recovered in 12 to 48 h after operation, no surgical complication occurred; Acute rejection postoperatively occurred in 2 patients and reversed after treatment. Now 4 patients were survived for 38, 17, 11, 7 months respectively with good liver function, and 3 of them went to work again.Conclusion EOLT is an effective means to cure FHF. Choosing appropriate perioperative management and (operative) timing is essential to improve the successful rate of EOLT.

OBJECTIVE To analyze the characteristic of vancomycin-resistant Enterococcus(VRE) infection after orthotopic liver transplantation, and provide a basis to improve prophylaxis and therapy. METHODS A retrospective survey in 136 patients who underwent orthotopic liver transplantation was carried out to define the incidence, clinical feature and therapeutic outcome of VRE infection. RESULTS Eleven patients were infected by VRE in this study and the incidence of infection by VRE was 8.1% following liver transplantation. Totally 31 of the VRE isolates were isolated, including 26 Enterococcus faecium strains and 5 E. faecalis strains. Sites of VRE infection included abdomen(n=4), blood(n=2), and respiratory tract(n=2). In the other 3 patients, VRE was cultured from multiple sites. Among 11 patients with VRE infection, 4 were sensitive to teicoplanin, and 7 resistant to teicoplanin. So 4 patients received antibiotics with teicoplanin and 7 patients with linezolid. In this study, 10 patients were cured and 1 patient died of sepsis. CONCLUSIONS VRE has become an nosocomial pathogen of increasing importance in liver transplantation patients. The risk factor of VRE infection should be paid attention. Infection prophylaxis of VRE should be emphasized.

Objective To evaluate the clinical usefulness of 99m Tc MIBI imaging for the diagnosis of breast malignancy.Methods 195 patients with a total of 204 breast lesions were divided into three groups to undergo 99m Tc MIBI imaging and the results were compared with pathology.20 cases with normal breast served as control.Abnormal density showed by 99m Tc MIBI imaging in the breast(10% higher than surrounding structure) was regarded as positive.Results Of 100 breast cancer lesions,positive feature appeared in 92.Twelve out of 70 benign breast lesions showed positive imaging.Six out of 34 breast occult lesions were with positive imaging, among them 3 were finally found with carcinoma.No positive imaging was found in the control group.The diagnostic accuracy,sensitivity,specificity,positive predictive value,negative predictive value of 99m Tc MIBI was 92 0%,91 8%,92%,86%, and 92%,respectively.Conclusions[WT5”BZ] 99m Tc MIBI imaging has high sensitivity and accuracy in the diagnosis of breast cancer and in the differentiation between benign and malignant breast lesions.

Objective To observe the effect of cluster needling at scalp acupoints plus paraffin therapy on motor function in cerebral palsy patients.Method Forty eligible patients with spastic cerebral palsy were randomized into a control group and an experimental group, 20 cases in each group. The control group was intervened by cluster needling with long-time retaining of the needles plus Uyeda's approach and conventional rehabilitation trainings specifically for spastic cerebral palsy; the experimental group was intervened by paraffin therapy in addition to the treatment given to the control group. The interventions were conducted once a day, for a total of 8 weeks. The Gross Motor Function Measure-88 (GMFM-88) and Modified Ashworth Scale (MAS) were adopted to evaluate the motor function before and after the treatment.Result The GMFM-88 scores were significantly changed after the treatment in both groups (P<0.05), and there was a significant difference in comparing the GMFM-88 score between the two groups after the intervention (P<0.05). The MAS score was significantly changed after the intervention in the experimental group (P<0.05), while the score wasn't significantly changed in the control group (P>0.05); there was a significant difference in comparing the MAS score between the two groups after the intervention (P<0.05).Conclusion On the basis of conventional rehabilitation trainings, cluster needling at scalp acupoints plus paraffin therapy can produce a significant efficacy in improving the muscular tension and motor function, and benefit the development of cerebral palsy patients.

Objective To investigate effect of monosialotetrahexosy-1 ganglioside (GM1) on the autophagic neuronal death induced by spinal cord injury.Methods Ninety SD rats were randomly divided into sham group,isotonic saline group and GM1 group,with 30 rats per group.Spinal cord injury at T10 segment was induced by Allen method in the isotonic saline group and GM1 group.Expression of endogenous LC3 was detected by florescence microscope.Ratio of LC3-Ⅱ and LC3-Ⅰ,and expression of Beclin-1 were detected by Western blot.Results LC3 was significantly up-regulated in the isotonic saline group,as compared to the sham group (P ＜0.05).Also,an up-regulation of LC3 and a decline of autophagic body formation were observed in GM1 group,as compared to isotonic saline group (P ＜0.05).Expressions of LC3-Ⅱ and Beclin-1 and ratio of LC3-Ⅱ to LC3-Ⅰ were significantly increased in the isotonic saline group,as compared to the sham group (P ＜ 0.05).Expressions of LC3-Ⅱ and Beclin1 and ratio of LC3-Ⅱ to LC3-Ⅰ significantly were decreased in the GM1 group,when compared to the isotonic saline group (P ＜ 0.05).Conclusion GM1 inhibits autophagic neuronal death after spinal cord injury and hence exerts protective effect on the neurons.
