Objective To investigate the effect of MOTOmed movement therapy on balance and ability in the activities of daily living (ADL) of convalescing stroke patients with hemiplegia. Methods Forty convalescent stroke patients exhibiting hemiplegia were randomly divided into a treatment group and a control group with 20 cases in each group. The control group received routine rehabilitation training; the treatment group received MOTOmed training in addition. Balance function of all the patients was assessed using Berg's balance scale (BBS) , and the Barthel Index ( BI) was used to assess ADL ability at the beginning of the program and after 6 weeks of treatment. Results Balance and ADL ability improved significantly in both groups after 6 weeks of treatment. The effect in the treatment group was significantly better than in the control group. Balance and ADL ability were positively correlated. Conclusions Applying MOTOmed therapy along with routine rehabilitation training can distinctly improve balance and the ADL ability of hemiplegics after stroke.

Objective To evaluate different expressions of high mobility group box 1(HMGB1)and receptor for advanced glycation end products(RAGE)in placentas and their relationship with preeclampsia.Methods Fifteen early-onset pre-eclaraptic women(early-onset pre-eclampsia group),22 late-onset pre-eclamptic women(late-onset pre-eclampsia group)and 12 normotensive women(control group)in the third trimester were recruited at the Shengjing Hospital of China Medical University from March 2006 to March 2007.The localization and levels of HMGB1 and RAGE in placentas of the three groups were detected by the strept avidin biotin-peroxidose method.Results (1)Immunoreactivities to HMGB1:positive immnnostaining for HMGB1 was observed in trophoblast,macrophages,decidual cells,vascular muscle cells,endothelial cells and placental mesenchymal cells in the placentas from the pre-eclamptic women,while a low level of immunoreactivities was observed in the placentas from healthy pregnancies;the staining was observed within both the nuclei and the cytoplasm,mainly in the cytoplasm.The cytotrophoblast,especially the nuclei was extensively positive for HMGB1 in early-onset pre-eclampsia. (2)Immunoreactivities to RAGE:positive immunostaining for HMGB1 was observed in syncytiotrophoblast,macrophages and endothelial cells in the placentas from the preeclamptic women,while a low level of immunoreactivities was observed in the placentas from healthy pregnancies:the staining was in the cytoplasm and(or)cell membrane.The trophoblast was extensively positive for RAGE in early-onset pre-eclampsia.(3)Positive rate of HMGB1 expression:the expression of HMGB1 in early-onset group(73%,11/15)and late-onset group(64%,14/22)was significantly higher than that in normal group(17%,2/12;P<0.05),but no significant difference was found in early-onset group and late-onset group(P>0.05).(4)Positive rate of RAGE expression:the expression of RAGE in early-onset group(80%,12/15)and late-onset group (82%,18/22)was significantly higher than that in normal group(25%,3/12;P<0.05),but no significant difference was found in early-onset group and late-onset group(P>0.05).Conclusions The increased expression of HMGB1 and RACE in the placenta may play an important role in the pathogenesis of pre-eclampsis.The different locations may be associated with the occurrence of different onset types of pre-eclampsia.

The Met tyrosine kinase receptor is a widely expressed molecule, which mediates pleiotropic cellular responses following activation by its ligand, hepatocyte growth factor/scatter factor (HGF/SF). Previously, one of the authors identified an alternatively spliced form of Met (Met-SM) that lacked a single exon of a 47-amino-acid segment in the juxtamembrane domain. Here we report that Met-SM is a potent transforming gene in NIH3T3 mouse fibroblast cells. Met-SM-transfected NIH3T3 cells show stronger foci-forming activity than wild type-Met-transfected ones. In addition, Met-SM-transfected NIH3T3 cells form colonies in soft agar and are tumorigenic in athymic nu/nu mice. Furthermore, HGF/SF significantly increases the focus-forming activity of Met-SM comparing to wild type Met. The amount of protein and of tyrosine kinase activity of Met-SM accumulates to a high level following HGF/SF treatment. The accumulation of Met-SM correlated well with its delayed ubiquitination and increased stability. These results are consistent with the important role of the juxtamembrane domain in protein stability of Met receptor and suggest that the alternatively-spliced form may contribute to the development and progression of human cancer.

Objective To study the risk factors of hyperthyroid heart diseases(HHD) by analyzing clinical features of patients in order to provide a scientific basis for prevention and treatment of HHD. Methods Nine hundred and eighty two cases were selected as objective from in-patient data of Thyroid Disease Treatment Centre of Shandong Province. The cases were divided into hyperthyroidism group and HHD group. The variables of etiology,sex, age, duration of disease, TSH, FT3, FT4 and TRAb were analyzed by comparative analysis. The risk factors were analyzed by logistic regression. Results The prevalence of hyperthyroidism complicated hyperthyroid heart disease was 7.7%(76/982), age, duration of diseases, FT3, TRAb in the HHD group were [(51.4 ± 11.5), (6.3 ±2.1) years, 21.6 pmol/L, 71.6 U/L], in hyperthyroidism group were [(37.9 ± 9.8), (2.6 ± 1.3) years, 14.9pmol/L, 49.6 U/L]. The differences were statistically significant(u = 9.93,15.23, T = 44954,48792.5, P ＜ 0.05)between the two groups. The factors of the older, higher FT3 and TRAb, longer duration, Graves disease (OR =1.751,1.470,1.483,1.445,1.234) increased the risk of HHD. Conclusions Graves disease, longer duration, old age, higher FT3 and TRAb are the risk factors of HHD. Timely prevention and control of risk factors is necessary to reduce the incidence of HHD.

Objective To explore the feasibility and effectiveness of lateral gastrocnemius muscle branch nerve transferring for deep pe-roneal nerve injury. Methods Thirty-two adult female Sprague-Dawley rats were divided into control group (n=8), sham group (n=8), nerve direct repairing group (n=8) and nerve transferring group (n=8). Twelve weeks after the anastomosis, the nerve anastomosis was observed vi-sually, the length of lateral of gastrocnemius muscle branch (L1), the diameter at the point of entering muscle (D1), the maximum detachable length of nervus peroneus communis (L2), the diameter of deep peroneal nerve (D2) and the distance between branch point and neck of fibu-la (S) were measured. The peroneal nerve functional index (PFI), the amplitude of compound muscle action potential (CMAP), nerve con-duction velocity (NCV), the weight of the tibialis anterior and the creatine kinase (CK) activity of theanterior tibial were compared among groups. Results L10.05). Conclusion It is feasible that lateral head muscular branches of gastrocnemius nerve transferring can repair deep peroneal nerve injury, which is needed to separate superficial peroneal nerve and deep peroneal nerve in the epineurium without damaging nerve for tension free neuroanastomosis. Lateral head muscular branches of gastrocnemius nerve transferring can repair the func-tion after deep peroneal nerve injury.
