OBJECTIVE: To evaluate the efficacy and safety of tacrolimus (FK506) instead of cyclosporine (CsA) in renal transplant recipients with hepatic impairment. METHODS: Eighteen patients with hepatic impairment, including 10 male and 8 females, aged 19-68 years (mean aged 40 years), 2 out of them suffered diabetes mellitus, 1 of them had hepatitis B prior to operation. After operation, all patients were treated with CsA 6 mg/(kg?d), the mass concentration was changed from 250-400 ?g/L at 1 month after operation to 250 ?g/L after half year. Totally 30 mg/d prednisone was used at first and changed to 20 mg/d at 1 month after operation. Mycophenolate was applied with 1.5 g/d, or azothioprine 50-100 mg/d. FK506 was used instead of CsA when alanine aminotransferase was over 1 500 nkat/L, with over 25.1 ?mol/L bilirubin direct. The initial dose of FK506 was 0.1 mg/(kg?d) at the second day after drug withdrawal and adjusted to base on its blood trough levels and the degree of hepatic impairment. The dosage of mycophenolate or prednisone was invariably. RESULTS: Hepatic function and bilirubin metabolism of all patients were returned to normal leverl without reject reaction in 15-60 days. One patient, who had severe hepatic impairment, was recovered in 46 days. Five patients had high blood sugar levels, and one had high blood cholesterol. After hypoglycemic and cholesterol lowering therapy, the blood glucose was controlled below 7.5 mmol/L from at the beginning of (16.7?2.8) mmol/L, and the blood fat was kept in a normal level. CONCLUSION: FK506 substituting for CsA can recover hepatic function with high safety in recipients with hepatic impairment.

Objective To analyze the practical experiences of design and its clinical application of custom-made tumor prostheses of knee. Methods A retrospective study of 41 cases of distal femur or proximal tibia tumors treated surgically from June 1999 to October 2002, was carried out. In the study, there were 29 males and 12 females aging from 11 to 69 years with an average of 35.0 years. The location of tumors were at distal femur in 23 cases and 9 cases at proximal tibia, of which 15 were osteosarcoma, 13 giant cell tumor, 3 chondrosarcoma, 5 solitary metastatic bone tumor, and 1 each of fibrosarcoma, malignant fibrohistocytoma, Ewings sarcoma, small round cell sarcoma and syndesmofibroma. The custom-made semi-constrained knee prosthesis with femoral or tibial component was implanted after extra-capsular resection of the tumor bone segment. A special femoral component with elongated construction was used in an 11-year old case for further femur lengthening. Resection of femoral artery involved by tumor and reparation by great saphenous vein was performed in one case. Results The operations of the 41 cases were all smoothly performed. 33 cases were followed up from 8 to 37 months with an average of 20.2 months. The daily life ability was recovered in 3 months after the operation. Among them, no loosening or failure of the prostheses was found, and local recurrence was found in 2 cases and distant metastasis in 3 cases. The design of knee prosthesis could provide some proper internal/external rotation and adduction/abduction movements accompanying with the flexion and extension of the knee joint without affecting the stability of the joint. For the case of proximal tibia tumor, a special design and surgical technique was developed to provide the reconstruction of patellar ligament insertion with rather good results; and the recovery of knee extension and stability were satisfied. Conclusion The custom-made semi-constrained tumor prosthesis of knee could be used as an effective method for the limb-savage management either the distal femur or proximal tibia tumor cases.

Objective To study the effectiveness of the complete ureterel reconstruction using bladder flap after cadaveric renal transplantaion.Methods In 13 recipients with complete necrosis of ureter after renal transplant from July 1995 to October 2003, tubelike bladder flaps were applied to ureteraplasty substitute for the necrosis ureter. Artificial pyeloureterostomy was performed and double T tubes were used as the stents. Routine drainage-tubes were placed in incisions. Results All patients were successful in ureteral reconstruction. The renal function of 10 patients was improved significantly 4 weeks postoperation. Nephrectomy was performed in one patient because of severe circumrenal infection 7 days after operation. One-year survival rate of recipients and allografts was ~100 % (13/13) and ~92.3 % (10/13) respectively. Urine reflow occurred in 2 patients during a follow-up of 12 months. Conclusion The use of bladder flap for ureteral reconstruction is an effective technique for total autograft ureteral necrosis.

[Objective]To observe expression of inducible nitric oxide synthase and peroxynitrite anion around the prostheses,and study the relationship between the osteolysis and inducible nitric oxide synthase peroxyni-trite.[Method]Interface tissues were obtained at three Delee-Charnley acetabular sections and seven Gruen femur sections in six revision total hip arthroplasty surgery. The tissues were prepared for immunohistochemical assays to determine the expression of iNOS and nit rotyrosine (NT)-a specific“footprint”of peroxynitrite. Pre-revision X-ray films were observed to determine the incidence of osteolysis regions and non-osteolysis regions. The correlation between the positive cells and the severity of osteolysis were analyzed and compared.[Result]Data showed that zone Ⅲ has much higher iNOS positive immunostaining than that of zone Ⅰ and Ⅱ at acetabulum, and the expression of zone 1、2、6、7 was significantly higher than the other zone at femur(P

[Objective]To observe the change of children necrotic femoral head repairing under low stress environment and to explore the effect of low stress environment on Perthes disease.[Method]The sick coxa was supported by Coxa Multi-functional External Fixation Shoring Fixator,which decreased femoral head stress and creates a low-stress environment for the sick coxa.Meanwhile,the affected extremity was kept abduction and internal rotation in order to increase femoral head containment.The coxa could flex and extend partly on sagittal plane.Twenty-eight patients(32 hips) were followed up with mean follow-up time of 3 years and 5 months(2~7 years).The radiological characteristics of pre-and post-operation was analyzed.[Result]At 3 months postoperatively,joint space was broadened,high density necrosis shadow became little and little,the femoral head became full,height of the femoral head epiphysis increased.If epiphyseal nucleus fragmentation vaded epiphyseal plate,the big head and pachy-neck and the subluxation of coxa would finally result.[Conclusion]Under low stress environment,child necrotic femoral head could be repaired.The prognosis is related to Catterall stage of Perthes disease.On Catterall Ⅱ and Ⅲ stage,the curative effect is fairly good.But on Catterall Ⅳ stage,the curative effect is not evident.

Objective: To develop Chinese Marital Motivation and Reason Inventory (CMMRI) and examine it's reliability and validity. Methods: A 40-items, self-report measure of marital motivation and reason was developed based definition of marital motivation and reason and clinical experiences. The test-retest reliability, split-half reliability, internal consistency reliability, construct validity, and empirical validity were examined in the general sample of 1303 subjects, retest sample of 52 subjects, and validity sample of 95 subjects, aged from 6 to 91 years. Results: The stability coefficients, split-half reliability, Cronbach's ?coefficients were 0.62~0.80, 0.61~0.79 and 0.62~0.80 for 4 dimensions. There were significant differences between subjects in separation and divorcee and subjects in marriage on the CMMRI. In the confirmatory analysis of four factors model, fit statistics for the model best explained the observed relationships between the item scores and they attained the lower x2/df ratios and RMSEA, and higher IFI, TLI, CFI, PNFI and PCFI. Conclusion: The stability, internal consistency, and validity of the CMMRI are good and meet with psychometric standard.

Objective To evaluate the middle-term effect of laparoscopic uterine artery occlusion combined with ascendant myomectomy (LUAO-M) for multiple uterine myomas. Methods The uterine artery was isolated and occluded with Kleppinger bipolar forceps (Sabre 2400,ASPEN LABS USA) or PK forceps (Gyrus Medical Limited Inc UK) under a laparoscope. Then dissection was performed on the surface of pseudo capsule with Kleppinger unipolar needle (Sabre 2400,ASPEN LABS USA) or PK needle (Gyrus Medical Limited Inc UK),and the target myoma was stripped out of the tumor bed with the Separate-Scoop device. Afterwards,repair of the incision was carried out in one layer with interrupted single stitch by Absorbable VICRYL suture (Johnson VICRYL ETHICON USA). Results The mean operation time was (102?36) min and mean blood loss was (88.7?58.4) ml. The mean hospital stay after the operation was (7.9?0.2) d,and febrile morbidity was 5.1% (5/98). Complications included two cases of subcutaneous emphysema and one case of ileus;no other severe complications occurred. Of the patients,98 cases were followed-up for 21 to 52 months (mean,36.3 months),during the period they were visited by a mean of 3.6 times,which showed a correction rate of menstruation abnormality of 95.9% (4/98),rate of uterine volume reduction of 57.7%,and rate of recurrent myoma of 3.1% (3/98). Conclusion LUAO-M shows a good clinical outcome and middle-term effect for multiple uterine myomas.
