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.

Background Choroidal melanoma(CM)is a common form of primary ocular cancer in adults.It is reported that indomethacin has inhibitory effect on many tumor in vitro and in vivo,but whether it can inhibit the growth of CM has not been published. Objective This study was to investigate the anti-tumor activity of indomethacin on the growth of human CM OCM-1 cell xenografts in nude mice. Methods OCM-1 cells were subcutaneously implanted on 24 SPF female BALB/C.nu/nu nude mice to establish ectopic models of human CM.The nude mice with the tumor 5 mm were randomly divided into 4 groups:untreated group,normal saline solution(NS) group,indomethacin 1 ms/kg group,indomethacin 2 ms/kg group.The 1 mS/kg or 2 ms/kg indomethacin was intraperitoneally injected for 14 consecutive days in indomethacin 1 ms/kg group and indomethacin 2 me/kg group respectively.and 0.2 ml of 2%NS-DMSO was used at a same way in the NS group.No any agent was used as the untreated group.The volume and weight of implanted tumor as well as inhibitory rates of indomethaein on tumor were calculated.The expression of ki67 and survivin proteins were measured with immunohistochemistry,and the expression of survivin mRNA in CM was assessed by RT-PCR. ResuIts The tumor of indomethacin treatment group was reduced in volume and weight with a significant difference between treatment group and control group as well as indomethacin 1 ms/ks group and indomethacin 2 ms/kg group(P＜0.05).The inhibitory rate of indomethacin 1 ms/kg and 2 ms/kg for tumor was 22.86%,48.00%respectively.The prolifiration index (PI)of ki67 in these 4 groups were (76.73±3.34)%,(73.30±2.95)%,(55.97±2.24)%,(32.87±2.91)%respectively,and significant difference was found in PI between indomethacin 2 mg/kg group and untreated group or NS group(P＜0.05),but there was not significant difference between indomethacin 1 mg/kg and 2 ms/kg group(P＞0.05).Compared with the control group,the indomethacin treatment groups showed the decreased expression of survivin protein and mRNA,and significant difference was found between indomethaein 2 ms/kg group and untreated group or NS group(P＜0.05),however,no significant difference was found between indomethacin 1 mg/kg and 2 mg/kg group(P＞0.05). Conclusion Indomethacin inhibits the growth of CM in nude mice through inhibiting the expression of survivin in the tumor and accelerating cell apoptosis and inhibiting tumor cell proliferation.

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.

Objective To investigate the effects of Epigallocatechin gallate(EGCG)on IL-1βinduced MIN6 cells apoptosis. M.Methods The experiment group was divided into control group,IL-1β group,IL-1β+ EGCG low concentration group and IL-1β+EGCG high concentration group.Cell activity was detected by CCK8.Insulin secretion was detected by ELISA.cell apoptosis was detected by flow cytometry.The mitochondrial membrane potential was detected by flow cytometry.ATP content and cell ac-tivity of ROS were detected by colorimetry and chemiluminescence method.Results Compared with normal group,IL-1β group showed much lower cell activity,insulin secretion,cell mitochondrial membrane potential and ATP content,and at the same time IL-1βgroup had significantly higher cell apoptosis and ROS activities.After given EGCG,both low concentration group and high con-centration group had higher cell activity,insulin secretion,cell mitochondrial membrane potential and ATP content,at the same time lower cell apoptosis and ROS activities was showed.And the IL-1β+EGCG high concentration group worked more powerful.Con-clusion EGCG has protective effects on IL-1βinduced MIN6 cells apoptosis.Its mechanism may be related to increasing the content of the ATP and mitochondrial membrane potential and protecting mitochondrial function as well reducing the activity of ROS.
