Objective To explore the effects of upper limb robot-assisted therapy on motor function and activities of daily living in con-valescent stroke patients. Methods From June to September, 2016, 12 chronic stroke patients at their first-ever stroke were enrolled and ran-domized into experimental group (n=6) and control group (n=6). Both groups received routine rehabilitation. Additional robot-assisted thera-py was provided to the experimental group, and additional repetitive movement training was provided to the control group, 20 minutes a day, five days a week for four weeks. Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Ashworth Scale (MAS) and Func-tional Independent Measure (FIM) were used to assess the motor function of the upper limbs and hands, the muscular tension of shoulder and elbow, and activities of daily living (ADL) before and after treatment. Results After treatment, the scores of FMA-UE and FIM were bet-ter in both groups (Z>2.032, P<0.05), and no significant difference was found between two groups (t<0.723, P>0.05), however, the scores were a little bit higher in the experimental group than in the control group. After treatment, for the experimental group, the MAS scores of shoulder abduction/adduction and elbow flexion/extension improved (Z>2.121, P<0.05);for the control group, the MAS scores of shoulder abduction/adduction improved (Z>2.000, P<0.05), but the MAS scores of elbow flexion/extension were not significantly different (Z<1.890,P>0.05). There was no significant difference in the MAS scores of shoulder abduction/adduction and elbow flexion/extension between two group (Z<1.734, P>0.05). The moving trail recorded by the computer, gradually became a regular pattern from the mass, saying the motor control ability became better. Conclusion Upper limb robot-assisted therapy can promote the recovery of the motor function of upper limbs and ADL in convalescent stroke patient, similar to the repetitive movement training.

Objective To establish a real time fluorescent quantitative revers transcripatase PCR(FQ-RT-PCR) method to detect the expression level of TNF-related apoptosis inducing ligand (TRAIL) mRNA in peripheral blood mononuclear ceils (PBMC) and determine its expression level in healthy donors, HBV-caused cirrhosis patients and PBC ones. Methods Specific primers and Taqman-MGB probe were designed and β-actin was used as endogenous control. The amplified fragment was obtained by RT-PCR. The quantitative template was constructed and then the fluorescent intensity was documented on the ABI Prism7000 analyzer. The standard curve was established, according to which, the TRAIl. mRNA levels in 30 healthy individuals, 30 patients with primary biliary cirrhosis (PBC) and 25 ones with HBV-caused cirrhosis were calculated automatically by software after the values of cycle threshold (Ct) were detected continuously during amplification. Results The linear detection range of the assay for TRAIL gene was 103 - 109 copies/ ug RNA ( r=-0.997). The coefficients of variation of both intra-and inter-assay reproducibility for high concentration samples were 5.6% and 6. 3% , respectively, and those for low concentration samples were12.5% and 14. 6%. The TRAIL mRNA expression level in PBC patients was [ (3.3±2.5)×105copies/ugRNA] significantly higher than that of healthy control [ (0.5±0.2)×105 copies/ug RNA ] (t=5.994,P <0.01). TRAIl. mRNA level of HBV-caused cirrhosis patients[ (2.1±0.9)×105 copies/ug RNA] wasalso significantly elevated (t=8.536, P<0.01). However, the difference between these two diseased groups had no significance. Conclusion We have successfully set up a FQ-RT-PCR method for detecting TRAIL gene expression and found that its expression levels of peripheral blood mononuelear cells in PBC and HBV caused cirrhosis patients are elevated, which provides a new insight into mechanism study of liver injury caused by cirrhosis.

Purpose To investigate the diameter change of dorsal root ganglion (DRG) in lumbar disc herniation using three-dimensional MR neurography. Materials and Methods Sixty-ifve patients with lumbar disc herniation and 30 healthy volunteers were selected. Bilateral DRG diameter was measured using MR three-dimensional constructive interference steady state (3D-CISS) sequence at the level of L3-S1 in the control group and at the level of herniation disc in patient group including central and lateral subgroups. The relationship between the sagittal index and DRG diameter at the level of herniation disc was analyzed. Results In the control group, the DRG diameters increased from the level of L3 to S1. The DRG diameters of the central subgroup were bigger than those of the control group (t=-2.485--2.253, P<0.05). The DRG diameters of the lateral subgroup were bigger on the diseased side than the contralateral side (t=1.956-2.432, P<0.05). The DRG diameters of the contralateral side in lateral subgroup were slightly bigger than those of control group without statistical signiifcance (t=-1.248--0.981, P>0.05). The sagittal index was not correlated with DRG diameter. Conclusion 3D-CISS sequence clearly demonstrates morphological changes of lumbosacral nerve root and measures its diameter.

Background:Gastrointestinal carcinoids are prone to be neglected in clinical practice because of the poor specific symptoms in early stage. Aims:To analyze the clinicopathological characteristics,treatment modalities and prognosis of a series of cases of gastrointestinal carcinoids for strengthening the understanding of the disease. Methods:A total of 116 patients diagnosed as gastrointestinal carcinoids by pathology from Jan. 1997 to Jan. 2010 in 8 hospitals at Wuhan were enrolled in this retrospective study. Data on sex,age,major symptoms,diagnostic approaches,treatment modalities, pathological features and prognosis, etc. were collected and analyzed. Results:The most common sites of the gastrointestinal carcinoids were rectum(59. 5%)and stomach(19. 8%);the most common symptoms were abdominal pain,abdominal distention and hematochezia. The positivity rates of immunohistochemical marker NSE,Syn and CgA were 92. 7%,87. 5% and 62. 5%,respectively. The proportion of stomach carcinoids with diameter larger than 2 cm was 73. 9%, and that of rectal carcinoids was only 13. 0%(P <0. 001). Most of the gastric carcinoids(81. 8%)infiltrated into or breakthrough the serosa;the rate of lymph node involvement in gastric carcinoids was significantly higher than that in rectal carcinoids(72. 7% vs. 17. 1%,P<0. 001),while typical carcinoids were less common in stomach than in rectum(60. 9%vs. 95. 7%,P<0. 001). Only one(4. 3%)gastric carcinoid patient underwent endoscopic therapy,while that for rectal carcinoids was 24 cases(34. 8%,P=0. 003). Surgical operation was the main therapeutic method for both gastric and rectal carcinoids. The 3-and 5-year survival rates for rectal carcinoids were 92. 8% and 62. 3%,respectively,and those for gastric carcinoids were 62. 6% and 49. 2%,respectively;there were no significant differences between the two groups(P>0. 05). Conclusions:Gastrointestinal carcinoids enrolled in this study distributed mainly in rectum and stomach. As compared with rectal carcinoids,gastric carcinoids were more advanced in disease stage with poorer prognosis. Regular health checks, strengthening the understanding of the disease,and grasping the specificities of carcinoids distributed at different sites might be helpful for the early diagnosis and treatment of gastrointestinal carcinoids,thus improving the survival rate.
