Objective To investigate the evidence of cortical reorganization in stroke hemiplegia treated with constraint-induced movement therapy(CIMT)by fMRI.Methods Five patients with chronic stroke were evaluated with the Action Research Arm Test(ARAT).The functional MRI(fMRI)was performed on a 3.0-T MRI with echo-planar imaging.The subjects were required to finish the finger-tapping task and undergo fMRI before and after CIMT.A block design was used for the inspection.Results After CIMT,the function of upper limb(sick side)of patients improved significantly assessed by ARAT(P<0.001),and cortical reorganization was found on fMRI.Conclusion CIMT can improve motor function of upper limb of chronic stroke patients with hemiplegia and induce cortical reorganization as measured by fMRI.

Objective To evaluate the efficacy and toxicity of combined pegylated liposomaldoxorubicin (PLD) and carboplatin in the treatment of patients with recurrent epithelial ovarian cancer.Methods We retrospectively reviewed 67 patients with recurrent epithelial ovarian cancer or primaryperitoneal adenocarcinoma (8 eases) who were treated with combined PLD and earboplatin. The responserate, survival and toxicity were evaluated. The mean age for 67 patients was 52.1 (39-76) years. All ofthem received eytoreductive surgery followed by platinum-based chemotherapy either with paclitaxel orcyclophosphamide and doxorubicin after diagnosis. Combined PLD and carboplatin was used as first orsecond-line treatment or even after multiple lines of treatment after disease recurred. Patients were treatedwith PLD at 35-40 mg/m2combined with carboplatin at an area under curve ( AUC ) of 5 once every 4weeks. Results Forty-nine. Patients were evaluable for response. Twenty-three (47%) patients had acomplete response, 13 (27%) had a partial response, 3 (6%) had stable disease and 10 (20%) hadprogressive disease. The estimated median progression-free survival (PFS) was 8 months. The 1-year and 2-year survival rates were 73% and 55%, respectively. All of the 67 patients were evaluated for toxicity. Thetreatment was terminated in 2 patients due to allergic-like infusion reaction. Four patients who had acuteinfusion reaction with shortness of breath and tightness of chest did not terminate the treatment because nosuch reaction occurred when restarted the infusion. There were 2 patients with G2and 3 patients with G3hand-foot syndrome, 2 patients had G4stomatitis, and 8 patients had G3leukopeni,, No G4leukopenia orcardiotoxicity eceurred. Conclusion The combination of PLD and carboplatin is an active and wellotolerated regimen in the treatment of patients with recurrent epithelial ovarian cancer.

OBJECTIVETo explore the operation methods and clinical effects of transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament in treating complete acromioclavicular joint dislocation.
METHODSFrom January 2006 to June 2012,26 patients with acute complete acromioclavicular joint dislocation underwent surgery. Transfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional clavical hoot plate and Kirschner wires fixation, were performed in all the patients. Among the patients, 18 patients were male and 8 patients were female, with an average age of 36.7 years old (ranged from 25 to 51 years). The duration from injury to operation was from 3 to 12 days with an average of 5 days. According to the Rockwood classification, 4 cases were grade III and 22 cases were grade V . Clinical manifestation included local swelling, tenderness with snapping, limitation of shoulder joint motion. In preoperative bilateral shoulder joint X-rays, the injured coracoclavicular distance was (16.2 ± 5.0) mm which was significantly wider than that of uninjured sides (7.6 ± 1.0) mm. Clinical results were evaluated according to X-rays and Constant-Murley score.
RESULTSAll incisions obtained primary healing after operation without complication of infection, internal fixation breakage, redislocation. All the patients were followed up from 12 to 30 months with an average of 18 months. Kirschner wires and internal fixation plate were removed at 1 month and 8-10 months after operation, respectively. At final follow-up, the motion of shoulder joint recovered to normal and a no pain joint was obtained. According to Constant-Murley score, 24 cases got excellent results and 2 cases good. There was no significant difference after operation between the injured coracoclavicular distance and the uninjured contralateral side [(7.7 ± 1.2) mm vs (7.6 ± 1.0) mm), P > 0.05].
CONCLUSIONTransfer of the medial half of the coracoacromial ligament to reconstruct the coracoclavicular ligament, additional fixation using hook plate and Kirschner wires is the effective surgical method in treating complete acute acromioclavicular joint dislocation.

Objective To investigate the possible origin of ovarian epithelial inclusions and its relationship with the low-grade ovarian serous carcinoma.Methods By comparatively evaluating the morphologic (secretory and ciliated cell distribution ) and immunophenotypic [using paired box gene 8 (PAX8),tubulin,calretinin,and Ki-67 as first antibodies] attributes of ovarian epithelial inclusions,the normal tubal epithelium,and the ovarian tumors,all adnexal tissues from a total of 198 patients were studied,including 116 adnexae removed for non-neoplastic indications,53 serous cystadenomas,44 serous borderline tumors,and 41 low-grade serous carcinomas,which were collected from Qilu Hospital of Shandong University and University of Arizona in USA.Immunohistochemical single staining was used to detect the expressions of PAX8,tubulin,calretinin,and Ki-67 in the two groups,while immunohistochemical double staining of PAX8/calretinin was used to figure out the immunophenotype of various ovarian epithelial inclusions in a more intuitive way.Results With immunohistochemical single staining of PAX8 and calretinin,the vast majority (90%,54/60) of ovarian surface epithelia displayed a mesothelial phenotype [calretinin(+),PAX8 (-)],whereas 10% (6/60)of the cases displayed foci with tubal phenotype [calretinin(-),PAX8 (+)].In contrast,most (79%,728/921 ) of the ovarian epithelial inclusions displayed a tubal phenotype,though 21% (193/921) of the ovarian epithelial inclusions showed a mesothelial phenotype.It was further proved by immunohistochemical double staining of PAX8/ calretinin.Secretory and ciliated cells were found in the ovarian epithelial inclusions with tubal phenotype.There was a progressive increase in the secretory/ciliated cells ratio and proliferative index,from ovarian epithelial inclusions/cystadenomas to borderline tumors to low-grade serous carcinoma,according to the expression of tubulin and Ki-67.Conclusions The findings make a strong argument that the ovarian epithelial inclusions displaying a tubal phenotype with PAX8 (+),calretinin (-) is likely derived from fallopian tube rather than through Mullerian metaplasia from ovarian surface epithelium.The increasing trend of secretory/ciliated cells ratio and proliferative index from ovarian epithelial inclusions/cystadenomas to borderline tumors to low-grade serous carcinoma indicates that the latter is a clonal expansion of secretory cells.Genetic and molecular studies are needed to further confirm these findings.
