tralateral parietal lobe. Conclusions CIMT can improve the patients' upper-limb function effectively. The constraint-induced movement of the affected arm during CIMT appears to induce cortical reorganization and compensation as measured by fMRL

Background Posterior capsular opacification (PCO) following the extracapsular extract of cataract is associated with the proliferation and migration of residual lens epithelial cells (LECs).Study showed that the incidence of PCO is higher in diabetic patients than those of non-diabetes.So if insulin-like growth factor-1 (IGF-1) participates in the pathogenesis of PCO deserve research.Objective This study was to explore the active mechanism of IGF-1/IGF-1 receptor (IGF-1 R) system in the migration of LECs and offer theoretical basis for clinical prevention and treatment of PCO.Methods Human lens epithelial cell lines (HLEC-B3) were cultured and passaged in DMEM.The cells were identified using fluorescence immunocytometry.IGF-1 with the concentrations of 0,30,90 μg/L were added into the medium separately for 48 hours.The numbers of migrated cells were calculated by Transwell test.The cells were cultured in DMEM containing 0,1.5,30,60,90 μg/L IGF-1,and the expressions of IGF-1 Rα and IGF-1Rβ in the cells were assayed and compared by Western bolt.Results The cultured showed the positive response for α-crystallin anibody with red fluorescence in the cellular membrane.Twelve hours after Transwell incubation,the number of migrated cells (Median) was 0(0,1),10(10,11) and 29(27,31) in the 0 μg/L IGF-1 group,30 μg/L IGF-1 group and 90 μg/L IGF-1 group,respectively,showing a significant difference among the 3 groups (Z=12.610,P=0.002).The number of migrated cells in the 30 μg/L IGF-1 group and 90 μg/L IGF-1 group was significantly more than that of the 0 μg/L IGF-1 group (both at P =0.008),and the number of migrated cells in the 90 μg/L IGF-1 group was significantly more than that of the 30 μg/L IGF-1group (P =0.009).Western blot assay showed that the expressions of IGF-1Rα and IGF-1Rβ in the cells were significantly different among the 0,1.5,30,60,90 μg/L IGF-1 groups (F=63.700,130.530,both P =0.000).The expressions of IGF-1 Rα and IGF-1Rβ were gradually elevated as increase of IGF-1 doses when then concentration of IGF-1 was ＞ 30 μg/L,with significant differences among the different concentrations groups (all at P＜0.05).Conclusions IGF-1 can upregulate the expressions of IGF-1R in HLEC-B3 cells in vitro in a dose-dependent manner.Also,IGF-1 enhances the migration ability of HLEC-B3 cells.These results suggest that activation of IGF-1/IGF-1R system may be associated with the pathogenesis of PCO.

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 explore the optimal acupuncture scheme in intervening hypermyotonia of the affected limbs in stroke.Method Eighty eligible stroke patients were randomly grouped by using the orthogonal experimental design, by adopting electroacupuncture (A), daily acupuncture frequency (B), and acupoint (C) as three factors, and two levels. A total of 20 treatment sessions were conducted. Each group was scored by using the Modified Ashworth Scale (MAS) before and after the treatment, and the safety was also evaluated.Result There was a significant difference in comparing the MAS score between the two different levels of factor A (P<0.05), while there were no significant differences in comparing the MAS scores between different levels of factor B and factor C (P<0.05). Concerning the improvement of the MAS scores of wrist, elbow, knee, and ankle joints, A2B1C1(i.e. electroacupuncture twice a day with acupoints from yin meridians) was the optimal treatment scheme.Conclusion Electroacupuncture twice a day is the optimal treatment scheme for hypermyotonia of the affected limbs in stroke, as it can effectively ease the hypermyotonia, improve the function and symptoms of the limbs, and has a satisfactory security evaluation.

Objective To summarize the experience in hepatic artery reconstruction in adult-to-adult living donor liver transplantation(ALDLT).Methods Fifty patients underwent ALDLT in our hospital from January 2002 to July 2006.All the hepatic a~ery reconstructions were done under surgical microscope.ResultsTwo patients(4%)presented with hepatic artery thrombosis.All the patients were followed up for 2 to 52 months (median,9 months),and no hepatic artery stenosis nor hepatic artery pseudoaneurysm occurred.The 1-year survival rate was 92%(46/50).Conclusions Systematic evaluation of hepatic artery reconstruction and use of microsurgical technique are key to the reduction of complications of hepatic artery reconstruction in ALDLT.

Objective To study the short-term outcome of the uterine fibroids treated with ultrasound-guided percutaneous microwave ablation therapy (PMAT) by magnetic resonance imaging (MRI). Methods PMAT was performed in 46 symptomatic patients with a total of 49 uterine fibroids. Pre-and post-contrast MRI was scanned at 3 days before treatment and 3 days after treatment to assess image changes of both fibroids and surrounding tissues. The fibroids were divided into group A (low signal), B (iso-signal), C (high signal) by the signal intensity on T2WI. According to the volume changes of fibroids and uterine, ablation rate and the reduction rate of the fibroids after treatment were calculated. Results There were 28, 17 and 4 fibroids in the group A, B and C respectively. Before the treatment the volume of the fibroids showed no statistical difference between the group A, B and C (P>0.05). Fibroids and uterine showed shrinkage after the treatment in the group A and B (t=5.644, 5.998, 6.725 and 4.678, all P<0.001). The fibroids ablation rate showed no statistical difference between the groups (F=0.852, P>0.05). Fibroids and uterine showed shrinkage after the treatment in the group C, but there was no obvious statistical difference. Conclusion The outcome of PAMT is good for the fibroids with different signal intensity on T2WI. But the fibroids with high signal intensity are not as sensitive as those with low or iso intensity to achieve the same ablation level.

The chemical consitituents from cytotoxic fraction of the Callicarpa nudiflora extract were isolated and purified by a combination of HP-20 macroporous resin, silica gel and Sephadex LH-20 column chromatographies. The structures were elucidated on the basis of the spectroscopic data and comparison of their spectroscopic data with reported data. The cytotoxicity was evaluated by the MTT assay. The 50% and 70% EtOH elutions of EtOH-extract showed significant cytotoxic activities, leading to the isolation of twelve compounds, which were identified as luteoloside(1), lutedin-4'-O-β-D-glucoside(2), 6-hydroxyluteolin-7-O-β-glucoside(3), lutedin-7-O-neohesperidoside(4), rhoifolin (5), luteolin-7, 4'-di-O-glucoside (6), forsythoside B (7), acteoside (8), alyssonoside (9), catalpol(10), nudifloside(11), and leonuride(12). Compounds 3-6, 10 and 12 were isolated from this genus for the first time, and compound 9 was isolated from this plant for the first time. The cytotoxicity assay demonstrated that flavonoids 1-6, in various concentrations, showed monolithic proliferation inhibitory activities against Hela, A549 and MCF-7 cell lines. Compounds 3, 5 and iridoid glycoside 11 possessed higher cytotoxicacivities. In short, flavonoids are the main components of cytotoxic extract from C. nudiflora, while phenylethanoid glycosides are the predominant ingredient but inactive to cancer cell lines. In addition, the minor iridoid glycoside expressed weak cytotoxic activity.
