Patients often suffered limb dysfunction after stroke. Upper limb and hand function recovered more slowly than lower limb, and became one of the research focuses in rehabilitation medicine. Timely and effective assessments were important to guide the rehabilitation treatment, evaluate the treatment efficacy and predict functional recovery of upper extremity and hand function. The assessment methods of upper limb and hand motor function included subjective evaluations and objective evaluations. The former included different kinds of scales, which involved assessment focusing on muscle, motor pattern, change of upper limb and hand function. While the latter contained biomechanics, neuroelectrophysiology, functional magnetic resonance imaging, upper limb robotic evaluation system and so on. Scales were proved to have good reliability and validity. But they could not show patients' function accurately because of the subjectivity, and the data could not be kept. Evaluation system with computer was applied in clinical practice more and more widely. In this review, we summarized the assessments on upper limb and hand motor function in patients after stroke.

Objective:To investigate the influence of Mannan Peptide combined with 5-Fu on the proliferation and apoptosis of HepG2 cells and to explore the related mechanism.Methods:HepG2 cells were divided into four groups:the control group,5-Fu group,Mannan Peptide group and combination group.Cell proliferation was evaluated by MTT assay.Flow cytometry was used to examine the cell cycle,proliferation index(PI)and apoptosis ratio.The expression of Bcl-2 protein in each group was analyzed by immunocytochemical method.Results:The inhibitive effect of 5-Fu plus Mannan Peptide was significantly stronger than that of Mannan Peptide alone,in a time-and dose-dependent manner. Cells were treated with medicine for 48 hours.Compared with cells in the control group and 5-Fu group,the percentage of cells in G_0/G_1 stage and the apoptosis ratio in the combination group were increased(P<0.01).In immunocytochemical analysis,the combination of Mannan Peptide and 5-Fu could significantly decrease Bcl-2 protein level(P<0.01).Conclusion:The combination of Mannan Peptide and 5-Fu can synergistically suppress the proliferation and induce apoptosis of human hepatoma HepG2 cells.The mechanism might be associated with down-regulation of Bcl-2 protein expression.

Esophageal carcinoma(EC) is one of the most common malignancies,which is difficult to cure.The median overall survival is less than 1 year,and the 5-year survival rate is less than 10％.Previous reports cited the incidence of brain metastasis (BM) from esophageal cancer to be approximately 0.4％ ～ 5.1％,and most of the reports come from America and Japan.The incidence of BM from EC is increased.However,because of the rarity of BM from EC,there are no established treatment guidelines.This report provides a comprehensive view of the clinical characteristics,treatment and prognosis of brain metastasis from esophageal carcinoma.

Conclusion:Mitochondrial associated protein FAHD1 and GDF-15 are associated with sepsis, and the diagnostic efficiency is improved when combined with PCT and CRP, which might provide experimental basis for screening diagnostic markers of sepsis.

Objective To observe the effects of gossypol on expressions of transforming growth factor-β1 (TGF-β1), fibronectin (FN) and 11β-hydroxysteroid dehydrogenase (11β-HSD) in nephridial tissue in rats with diabetes mellitus. Methods Thirty male Sprague-Dawley rats were randomly divided into three groups: normal control, type 2 diabetes and gossypol treatment group . After high-fat feeding for 4 weeks, the later two groups were injected with low dosage strepozotocin (30 mg/kg) intraperitoneally to induce type 2 diabetic rat model. The rats in gossypol treated group were given gossypol at the dosage of 15 mg/kg once per day for 4 weeks by gavage. And since the 5th week, the times of gavages had been changed into once per week at the same dosage and lasted to the 12th week . The levels of blood glucose, total cholesterol (TC), low density lipoprotein-cholesterol (LDL-c) were measured. Additionally, the morphological changes of the kidney were studied by light microscopy and transmission electron microscopy respectively. The mRNA expressions of TGF-β1, FN, 11β-HSD and 11β-HSD2 in nephridial tissue were assayed by semi-quantity RT-PCR. The protein expressions of TGF-β1 and FN in nephridial tissue were determined by immunohistochemistry. Results The blood levels of glucose, TC and LDL- c were increased significantly in type 2 diabetic group compared with normal control group(P<0. 01). The volume of glomerulus and the deposition of PAS positive substance in the glomerular interstitium were increased under light microscopy, and the glomerular basal membrane was thicker in type 2 diabetic group than those in normal control group under transmission electron microscopy. The mRNA and protein expressions of TGF-β1 and FN were increased(P<0. 01), and the mRNA expression of 11β-HSD2 was decreased(P<0. 05), while the mRNA expression of 11β-HSD1 was unchanged in type 2 diabetic group compared with normal control group. After the treatment of gossypol, the level of the blood glucose was significantly decreased(P< 0. 01), and the levels of TC, LDL-c showed a trend of decrease but had no statistical differences compared with type 2 diabetic group. The morphology of nephridial tissue was ameliorated in gossypol treatment group. The mRNA and protein expressions of TGF-β1 and FN were decreased(0. 16± 0. 02,0. 22±0. 05 ; 0. 24±0. 06,0. 33±0. 07, P< 0. 05), while the mRNA expressions of 11β-HSD1 and 11β-HSD2 were unchanged compared with type 2 diabetic group. Conclusions Gossypol can relieve the pathologic changes of nephridial tissue, inhibit the expressions of TGF-β1 and FN through decreasing blood glucose of rats with diabetes mellitus.

BACKGROUND: The study indicated that directed neural differentiation of bone marrow stromal cells (BMSCs) was associated with changes in local micro-environment in injured spinal cord following cerebral ischemia, in particular neurotrophic factor induction. Group pre-test has confirmed that acupuncture can increase the expression of vadous cytokines and neurotrophic factors to promote nerve regeneration and repair.OBJECTIVE: To observe the effects of electro-acupuncture combined with BMSC kansplantaUon on recovery of neurological function in rats with spinal cord injury.DESIGN, TIME AND SETTING: Randomized controlled animal experiments were performed at the Laboratory of Cell Biology,Harbin Medical University from March 2005 to July 2006.MATERIALS: A total of 80 pure healthy Sprague Dawley rats were selected. Eight were used for the isolation and culture of BMSCs, and the remaining 72 rats were equally and randomly divided into 4 groups: blank control group, cell transplantation group, electro-acupuncture group, and combination group. KWD-80811 pulse-type apparatus was produced by the third radio factory in Jiangsu Wujin production.METHODS: In vitro isolation and culture of the third passage of BMSCs were obtained and labeled by BrdU at hour 72 before transplantation, and BMSCs at 1 ×10 11/L were harvested for usa. Rat models of spinal cord injury were established in each group.Following model establishment, BMSC suspension was injected into the injured spinal cord near the junction of the gray matter and white matter in the cell transplantation group, totally 6 × 10<'5> cells. The same volume of phosphate buffer saline was infused into rats of the blank control group by the same method. In the electro-acupuncture group, at hour 24 after the successful model establishment, Jiaji Electroacupuncture Electroacupuncture instrument treatment was performed by pulse electro-acupuncture apparatus at 3.0-4.0 mm from median line in the upper and lower end of the spinous process vertebral body adjacent to open space for 20 minutes, once a day. In the combination group, rats underwent BMSC transplantation + Jiaji electro-acupuncture treatment. MAIN OUTCOME MEASURES: After transplantation for 3, 7, 14 days, neurological conditions were assessed by combined behavioral scores in rats with spinal cord injury. Glial fibrillary acidic protein and neuron-specific enolase expression was measured in BrdU-labeled BMSCs by immuno-double-labeling method.RESULTS: 3, 7, 14 days after injury, compared with the blank control group, significant differences in combined behavioral scores were determined in the call transplantation group, electro-acupuncture group, and combination group (P <0.05, 0.05, 0.01).The recovery of neurological function was significantly greater in the combination group than in the cell transplantation and electro-acupuncture groups (P < 0.05). No significant difference was detected between the cell transplantation group and the electro-acupunctura group (P > 0.05). Compared with blank control group, spinal cord structure was relatively complete in the cell transplantation group and electro-acupuncture group. The structure was more integrity in the combination group. Bone marrow stromal cell transplantation presented the organization BrdU-labeled cells in the lesion and the surrounding area, with obvious aggregation and survival. At day 14 following cell transplantation, positive rates of neuron-specific enolase and glial fibrillary acidic protein were respectively 7.2% and 1.5% in the call transplantation group, 7.9% and 2.1% in the combination group.CONCLUSION: The BMSCs after transplantation can survive in the host body. Electro-acupuncture could promote the differentiation of BMSCs into neural cells. Combination of electro-acupuncture and BMSC transplantation can significantly improve the motor and sensory function in rats with spinal cord injury.
