BACKGROUND: Limb salvage operations with preservation of the epiphysis (LSPPE) had been used clinically in order to overcome discrepancy of affected limb and poorer limb function, but more post-operation complications existed, including infection, grafting bone resorption, fracture and internal fixation cinch.OBJECTIVE: To study the clinical related matters of inactivated bone replantation with preservation of the epiphysis in children limb salvage with osteosarcoma.DESIGN: Clinical observation regularly.SETTING: General Hospital of Jinan Military Area Command of Chinese PLA.MATERIALS: Eleven patients corresponded selected standard and accepted treatment from January 1999 to January distal metastasis was found with lung X-ray check and CT scanning, the patient would be excluded this study. There were 5 males, 6 females, and the mean age of (8±2) years old (4-11 years). The disease history was 1-6 months.FO) were adopted. After 2 weeks of chemotherapy, the operations of inactivated bone replantation with preservation of the epiphysis were performed. The operation was performed under epidural or general anesthesia. The patient lied on operating table. The knee anteriomedialis incision was adopted. Firstly, femur periosteum was opened beyond proximal end 2-3 cm from tumor, subperiosteum stripping was done to the proximal femur, descend femur with wire saw, separated and disconnected aboral periosteum, blunt dissecting femur aboral blood vessel and nerves to the popliteal fossa,deligating blood vessel around the tumor. Attachment of gastroenemius was cut off. Epiphyseal plate was identified carefully. According to pre-operation MR, the distal femur descend level was determined and the femur was descend with electro-saw. It was determined with cytology that no tumor cell existed in descend level, and reconstruction of bone de-fect with inactivated tumor-bone shell with 95% alcohol and bone cement containing ADR (20 g bone cement: 10 mg ADR), the diaphysis was fixed by intramedullary nail and screws were inserted in the residual epiphysis for the osteosynthesis of the distal osteotomy. One drainage tube was placed into and closed incision The affected limb was protected with plaster cast. Post-operative treatment: Regular usage of antibiotics was adopted to prevent infection. The drainage tube was pulled out when drainage amount ＜ 50 Ml/24 hours. The progressive passive exercise was initiated during the protection of affected limb with plaster cast for 8 weeks. Twelve to 14 days after operation, stitches were taken out. The postoperative chemotherapy then initiated, drug and dosage were identified on the response to the preoperative chemotherapy. Eight weeks after operation, patients were permitted to walk with the protection of double crutches and ery analysis: To observe ncision healing and existing of nerve and blood vessel injure, or not. During follow-up, patient recoveries were determined with affected knee function, limb length, distal metastasis, post-operative complications and dynamic imaging inspection of bone healing.imaging inspection of bone healing.MAIN OUTCOME MEASURES: ① The response to chemotherapy was evaluated with tumor cell necrosis rate. ② Post-operative recovery was determined with parameters such as knee function, limb length, distal metastasis, etc. ③ Dynamic imaging inspection of bone healing.MAIN OUTCOME MEASURES: ① The response to chemotherapy was evaluated with tumor cell necrosis rate. ② Post-operative recovery was determined with parameters such as knee function, limb length, distal metastasis, etc. ③ Dynamic imaging inspection of bone healing.RESULTS:All patients in this study were done follow-up.①The histological response of 11 patients to preoperative chemotherapy were classified as 7 in gradeⅣ,4 ingrade Ⅲ.②Post-operation recovery:No nerve and blood vessel injury existed and all incision healed well,there was not incision infection and healing.Eleven patients were followed-up from 10 to 72 months.Three patients could flexed affected knee joint ≥110,90-110 in 3 cases,60-90 in 4 cases,＜60 in one patient .The length of both lower extremity equaled in 4 cases,the length of affected limb was shorter than 2.0 cm in 5 cases,2.0-3.0 cm in 2 cases. One patient with recurrence,two with metastasis,three died.Screw cinch in one patient and one patient with inactivated bone fracture. ③Dynamic imaging inspection: No recurrence was found around epiphysis. Essential bone healing existed between the inactivated bone and epiphysis,callus formation between the inactivated bone and diaphysis at 2 months after operation; more callus formed and 4 months; 6 months after operation,bone complete healing was found between the inactivated bone and diaphysis.④Post-operation recovery:During follow-up, a screw cinch was found in one patient, and dislodged the screw because of bone healing well. One patient underwent open reduction, bone grafting and internal fixation with encircle device because of inactivated bone fracture.four months of the operation, grafting bone healed well. At post-operative 24 months, the length of both lower extremities equaled and the affected knee flexed to 110°.CONCLUSION: Inactivated bone replantation with preserving epiphysis for osteosarcoma in children was propitious to recover limb function and keep limb length.

Objective To study the clinicopathological characteristics of hepatobiliary cystic neoplasms(cystadenoma and cystadenocarcinoma)in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 9 cases of cystic biliary tumors hospitalized in the People's Hospital of Rizhao City from May 1993 to May 2007.All cases were confirmed by operation and pathologic biopsy.Results Six cases were biliary cystadenoma with muhilocular cyst.The other three cases were biliary cystadenocarcinoma,two with single cyst and one with multilocular cyst.Of the three cystadenocarcinorna,two cases had mural nodules and one case had papillary excrescences and cystic wall thickening.Irregular thickening of internal sept.was shown in the multilocular cyst cases.Two had calcification.Enhancement of the wall.internal septa and nlasses were seen in all the malignant tumors on CT scans. Metastatic lymph node was found in one cage. Conclusion There were no special clinical characteristics in difierentiation between hiliary cystadenoma and cystadenocarcinoma. Single cyst, mural nodules and papillary excrescences,irregular thickening of cystic wall and internal septa,coarse calcification and metastatic lymph node increase the likelihood of the diagnosis of the malignant tumors.But the diagnostic differentiation between cystadenoma and cystadenocarcinoma depends on pathology.

Objective To investigate the efficacy and safety of pramipexole versus fluoxetine in the treatment of depression in Parkinson's disease ( PD). Methods A randomized, clinical trial of pramipexole versus fluoxetine treatment for 12 weeks in 50 patients suffering from combined PD and depression was accomplished. The efficacy and safety assessments of the treatments were performed at different time points. Results For the intent-to-treat (ITT) population, the Hamilton Depression Rating Scale (HAMD) scores decreased progressively in both the pramipexole and the fluoxetine group, and a between-time statistical analysis was significant for both groups. The efficacy proportion of patients who responded to the treatment, as defined by at least a 50% reduction in HAMD score, was 56. 0% in the pramipexole group versus 48. 0% in the fluoxetine group (χ~2 =0. 321, P>0. 05). Similarly, the proportion of patients who recovered, as defined by a final HAMD score ≤8, was 52. 0% in the pramipexole group versus 32. 0% in the fluoxetine group (χ~2 =2. 053, P>0. 05) , but the difference between the two treatments showed no statistical significance. At the endpoint, both the Unified Parkinson's Disease Rating Scale (UPDRS) part Ⅱ and part Ⅲ subscores improved in the pramipexole group, by a mean of 2. 9±3. 7 (t= 2.366, P<0.05) and7.2±5.1 (t=2.654, P< 0.05), respectively, and the latter was significantly different from the change in this variable of the fluoxetine group (P<0. 05). Spearman analysis showed that no relationship between HAMD score and UPDRS Part II or Part III subscore. The findings for the per-protocol (PP) population were consistent with the above results, except that the proportion of patients who recovered in the pramipexole group was significantly larger than that in the fluoxetine group. The adverse events in both groups were mild dizziness, nausea and anorexia. No significant difference was found in the frequencies of the adverse events between the pramipexole and fluoxetine group. Conclusions Pramipexole is effective and safe in the treatment of Chinese PD patients combined with depression.
