Objective To explore the effects of upper limb robot-assisted therapy on motor recovery in acute stroke patients. Methods From August, 2013 to September, 2014, 46 acute stroke patients at their first-ever stroke were enrolled and randomized into experimental group and control group with 23 cases in each group. Both groups received routine therapy. Additional robot-assisted therapy was provided to the experimental group, and additional repetitive movement training was provided to the control group, 30 minutes a day, 5 days a week for 12 weeks. Fugl-Meyer Assessment-Upper Limb (FM-UL), modified Ashworth Scale (MAS) and modified Barthel index (MBI) were used to assess the motor function of the upper limbs and hands, the muscular tension of elbow, and activities of daily living (ADL) before and after treatment. Results After treatment, the scores of FM-UA, MAS and MBI improved in both groups (t>3.856, Z>1.889, P<0.05), and the scores of FM-UA and MAS were better in the experiment group than in the control group (t=-2.386, Z=-2.625, P<0.05), however, there was no significant difference in the score of MBI between two groups (t=-1.326, P=0.098). Conclusion Upper limb robot-assisted therapy can facilitate the recovery of the motor function of upper limbs in acute stroke patient.

The purpose of this study was to investigate the cytotoxicity of the nickel ion and provide with basic data for the biological evaluation of those medical devices containing nickel. Seven cell lines were chosen. They were L929, h9c2(2-1), 293[HEK-293], hFOB1.19, THLE-3, H9 and IM-9 respectively. According to the principle of biological evaluation of medical devices, MTT method was chosen to test the cytotoxicity in different concentrations of nickel ion. For each cell line, the relative growth rate (RGR) was obtained and the cytotoxic grade was classified. Besides, IC50 values were calculated. As a result, it was found that the sensitivity was different among all cell lines. H9 was the most sensitive one, while the L929 was the most tolerant one. The concentration which is not above 1.25 mg/L was safe for all seven cell lines, because the cytotoxicity for all cells exposed in this concentration were not higher than grade 1. According to the criteria for medical devices, the concentrations not above 5 mg/L were safe for L929 cells. This result helps us to roughly assess the cytotoxicity and systematic toxicity caused by nickel contained in medical devices.

Objective To investigate in evaluation of various capacity requirement of probationer nurs-ing students by nurses in operation room in order to improve clinical teaching work. Methods A self-de-signed questionnaire was applied, 191 qualified teaching nurses from nine grade three A general hospitals in Beijing were invited to fdl the questionaires. The results underwent subsequent analysis. Results The teach-ers had high expectations for various capacity of the probationer nursing students. Conclusions Clinical teachers should establish feasible teaching scheme according to the existing teaching syllabus in order to in-crease teaching quality, make students gain new insights through reviewing old materials, so that they can mas-ter various technique in operation room in short time.

Objective To study the fecel-oral and blood transfusion of TT virus. Methods Paired feces and serum samples from 6 patients with type B and/or C hepatitis were tested for TTV DNA and its titers by PCR with seminested primers.Genotypes were determined after their sequences were compared with the original N22 and TA278 clone.Results TTV DNA was detected in sera from all patients,while it was detected in feces from 3 patients,including 2 with high viral titers in serum.The detection of fecal TTV DNA was dependent on the viral titers in serum.TTV isolates in 3 pairs of feces and serum had identical sequence of 222 base pairs.Their genotypes were 1a,1b and 2,respectively.Conclusion The excretion of TTV into feces indicates that TTV would be transmitted not only parenterally but also nonparenterally by a fecal-oral route.

Gallbladder carcinoma is a common malignancy of biliary system which associated with dismal outcomes.It is difficult to resect because of its various etiologic factors,difficulties of early diagnosis,high malignancy grade and early metastasis.A review is presented here to discuss the progress of extended radical operation for gallbladder carcinoma,and focused on the scope and complications of the resection.

Objective To study the expression of interleukin (IL-17A) in primary liver cancer (PHC) tissue and its clinical significance.Methods Reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry was performed respectively to detect the expression of IL-17A mRNA and CD34 in tumor tissues from 37 patients with PHC.Murine H22 cells cultured in vitro were exposed to IL-17A at different dosages (0.1,0.5,1.0,5.0,10,50,100,500,1000 ng/ml) and the cell proliferation was assayed by MTT.IL-17A was administered to the mice transplanted with H22 cancer cells via caudal vein and the tumor volume was measured by vernier caliper.Immunohistochemistry was used to detect the CD31 expression in H22 cancer tissues.Results IL-17A mRNA was detected in 26 of the 37 samples of primary liver cancer.The microvessel densities in IL-17A-positive samples and IL-17A-negative samples were 66.6 ± 2.5 and 26.7--2.5,respectively.The difference between two groups was significant (P＜0.01).The proliferation of H22 cells exposed to various dosages of IL-17A was not different (P＞0.05).The volume of murine tumor tissue in animals treated with IL-17A was (843.6± 90.9) mm3 and in untreated animals was (198.7±24.4) mm3 (P＜0.01).The microvessel density in treated group and control group was 71.9± 6.8 and 33.3 ± 2.9,respectively (P＜0.01).Conclusions The expression of IL-17A could be detected in a considerable proportion of primary liver cancers and correlated with angiogenesis.Exogenous IL-17A could not accelerate H22 cell proliferation in vitro but in vivo probably via enhancing angiogenesis.
