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 analyse the clinical features of pelvic insufficiency fractures (PIF) in patients with cervical cancer after radiotherapy and explore the risk factors affecting its occurrence .Methods 55 cases of patients with cervical cancer that used radia-tion therapy as a single treatment were chosen in our hospital from February 2007 to May 2010 and the clinical features were ana-lysed;The fractures of spine ,sacrum ,sacroiliac joint ,ilium and pubis and femoral were observed and the density of fifth lumbar (L5 ) vertebrae ,left and right sacrum were detected via the CT or MRI (Hounsfield Unit)after 2-year follow-up ,the different factors on the incidence of PIF were explored .Results 12 cases (19 sites) of patients in 55 patients occured PIF after follow-up 2years ,the cumulative incidence was 21 .82% ;the distribution of PIF parts were followed :lumbar vertebrae had 5 cases ,sacral had 5 cases ,pu-bis had 4 cases ,sacroiliac joint had 2 cases ,iliac had 2 cases and femoral head had 1 case .The incidence rate of PIF that density of fifth lumbar vertebrae was ≤130 HU and >130 HU were 16 .36% and 5 .45% respectively ,the PIF′incidence rate that density of left side of sacrum was≤ -35 HU and > -35 HU were 18 .18% and 3 .64% respectively ,the incidence rate of PIF that density of right side of sacrum was ≤ -35 HU and > -35 HU were 20 .00% and 1 .82% respectively ,the density of the three parts all had statistical difference on the incidence of PIF (P<0 .05) .Univariate analysis showed that menopausal status and the average density of CT had statistical effects on PIF (P<0 .05);Multiple analysis showed that the average density of CT was the independent factors affecting PIF′incidence after radiotherapy .Conclusion The patients with cervical cancer may occur pelvic insufficiency fracture af-ter radiotherapy ,and its incidence is related to menopausal status and bone mineral density .

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 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.

To explore the influence of matrix materials in complicate ingredients on traditional Chinese medicine and investigate the excipients selection model based on balanced release characteristics of multicomponents, the influence of HPMC (K4M, K15M, K100M) and Carbomer (934P, 971P, 974P) was illustrated by testing in vitro release of ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in Panax notoginseng saponins (model drug, PNS). According to in vitro release results of PNS matrix tablets in water and artificial intestinal juice, the release curves were analyzed with Peppas equation and simulating factor (f). Significant differences in k value and n value among ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 existed in various formulations. The release behaviors from various excipients could be described with Non-Fickian transport or super Case II transport pattern. The f2 values for ginsenoside-Rg1, ginsenoside-Rb1 and notoginsenoside-R1 in 971P matrix tablet containing 30% Carbomer 971P were 74.91, 53.45, 57.89 in water and 79.35, 55.51, 51.89 in artificial intestinal juice, respectively. The release profiles fit for the regulation of FDA. The result revealed that the balanced release rates of Rg1, Rb1 and R1 in 971P matrix tablet were obtained.
