Objective To investigate the influence of a multifaceted stroke telehome-care (THC) on extremities function, activities of daily living (ADL) and quality of life in stroke patients with hemiplegia. Methods A total of 52 stroke survivors in department of neurology were randomized to the THC intervention or usual care. The patients in the control group received conventional care, while those in the intervention group were additionally given a THC program over 3 months. The THC intervention includes motor imagery and adaptive strategies. Data collection was undertaken using the Fugl-Meyer Motor Assessment Scale (FMA), the Barthel Index (BI), the Stroke Impact Scale (SIS) at baseline, 3 months, and 6 months. Results At baseline, the scores of FMA, BI, and SIS in the intervention group were 53.62 ± 23.52, 54.04 ± 17.44, 179.96 ± 28.51, and while the scores of the control group were 50.96 ± 19.52, 49.46 ± 15.09, 169.23 ± 28.48. There were no pre-existing differences on any scale between the two groups (t=0.443, 1.012, 1.358, P > 0.05). At 3 months, the scores of FMA, BI, SIS in the control group were 53.54 ± 17.45, 50.77 ± 14.47, 76.19 ± 27.78, and were significantly lower than 78.38 ± 12.54, 74.62 ± 11.22, 228.54±22.63 in the THC group (t=5.895, 6.641, 7.449,P<0.01). At 6 months, the scores of FMA, BI, SIS in the control group were 57.88±17.89, 59.08±13.85, 183.92±26.56, and were significantly lower than 90.58 ± 9.60, 86.54 ± 9.88, 252.19 ± 20.10 in the THC group (t=8.211, 8.233, 10.451, P < 0.01). Conclusions A telehome-care program that provide distance training and education of disabled persons resulted in greater improvements in physical functioning, ADL and quality of life.

· AIM: To explore the relationship between the expression of Fas/FasL and the apoptosis in retinal ischemia/reperfusion injury of rats, as well as the therapeutic effects of basic fibroblast growth factor (bFGF)on the ischemic retina.injury were made by transiently elevating introcular pressure. A total of 28 rats were divided into Normal Group and Operative Group. The latter were subdivided into 1, 6, 12, 24, 48 and 72h after reperfusion, in which the left eyes of the rats were in the ischemia/reperfusion groups and the right ones were in the treatment groups (bFGF intracameral injection). Apoptosis was assessed by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labelling (TUNEL) method, and theexpression of Fas/FasL ligand was studied by strept avidin-biotin complex (SABC) immunohistochemistry.mai rats' retinae, but there were a significant number of TUNEL positive cells in 6-24h after transient ischemia followed by a decrease at 48h. The number of TUNEL positive cells reached a maximum at 24h after ischemia.The expression of Fas gradually increased as early as at 6h, reached a peak at 24h, then decreased at 48h. Similarly, the expression of Fas ligand was at peak in 24-48h in GCL and INL of retina. bFGF ministered before reperfusion inhibited apoptotsis and ameliorated the tissue damage. It also diminished Fas and FasL expression in ischemic/reperfused retina.siently elevated IOP induced apoptosis of cells in the retina. Fas/FasL may have an important role in the early events of the apoptotic pathways. bFGF can rescue RGCs from retinal ischemia/reperfusion injury through down-regulation of Fas and Fas ligand expression and may represent an important mechanism for therapeutic neuroprotection.

Rhubarb is a traditional Chinese medicine (TCM), wildly used in treating the disease of hyperlipidemia. However, its components are complicated, so that it is still difficult to clear the specific roles of its various components in blood lipids regulation in. So we decide to systematically study the anti- hyperlipidemia mechanism of rhubarb. We integrated multiple databases, based on entity grammar systems model, constructed molecular interaction network between the chemical constituents of rhubarb and hyperlipidemia. The network includes 231 nodes and 638 edges. Thus we infer the interactions of active targets and disease targets to clarify the anti-hyperlipidemia mechanism. And find that rhubarb can promote excretion of cholesterol; inhibit clotting factors and improve blood circulation; inhibit the release of inflammatory cytokines and maintain fat metabolism balance; inhibit cholesterol and triglyceride synthesis; and other ways to achieve lipid-lowering effect. Thus this study provides reference for novel drug development and component compatibility, and also gives a new way for the systematically study of acting mechanism of traditional Chinese medicine.

Background Allograft rejection is a main cause of failure of penetrating keratoplasty,especially in the patient with high risk of rejection condition.Previous study on allograft rejection mechanism focused on limbal and corneal neovascularization,but these factors did not explain all the phenomena of allograft rejection.Research found that immune cells appeared in iris and ciliary body when rejection occurred,but the relationship between these immune cells and allograft rejection is unclear Objective This study was to evaluate the relationship between diversity of vascular permeability in the iris and ciliary body and allograft rejection after penetrating keratoplasty.Methods Seventy clean eight-week-old BALB/c mice were divided into allogeneic corneal transplantation group (60 mice) and blank control group (10 mice).Allogeneic corneal transplantation was performed with the same age of C57BL/6 mice as donor and BALB/c mice as the recipients.The grafts were examined under the slit lamp microscope and scored based on the criteria of Hegde.The mice were sacrificed and iris and ciliary tissue were obtained 5,10 days and rejection after surgery.Immunohistochemistry and reverse transcription PCR (RT-PCR) was used respectively to detect the expression diversities of occludin,zonula occludens protein-1 (ZO-1),matrix metalloproteinase-9(MMP-9),major histocompatibility complex-Ⅱ (MHC-Ⅱ),and CCR5,CCR7 and their mRNA in iris and ciliary body.Image-J image analysis software was used to calculate the quantity of positive cells on iris wholemount,and absorbance of target genes (A values).The use and care of the experimental animals complied the ARVO Resolution on the Use of Animals in Research.Results The mean survival time of corneal gratts was (17±3) days after operation.The mean score was 0.6 in 5 days and 0.5 in 10 days,and 3.3 in 18 days after operation.Expression of ZO-1 reduced significantly,and that of MMP-9 increased obviously at the time of rejection.MHC Ⅱ + cells were scattered in iris and ciliary body in normal mice,and the number of the positive cells (cells/field) was increased after operation with a peak value when rejection occurred.A significant difference was seen between normal mice and rejection mice (1559.67±350.29 vs.4021.83±495.18) (P=0.000).The expressions of occludin mRNA and ZO-1 mRNA in the iris and ciliary body decreased obviously in the rejection mice.Compared with normal mice,theA value of ZO-1 and occluding were 36.74±3.13 vs.110.11±11.88 and 57.54±3.41 vs.59.90±3.50respectively,with significant differences between them (all P＜0.05).The expressions of MMP-9 mRNA,CCR5 mRNA and CCR7 mRNA in the iris and ciliary body increased gradually with the time lapse after operation and peaked when the rejection appeared.The A value of MMP-9 mRNA,CCR5 mRNA and CCR7 mRNA were significantly higher than those of normal mice (20.29±1.19 vs.2.77±0.85 for MMP-9 mRNA; 35.43±2.56 vs.9.11±0.29 for CCR5 mRNA,and 60.83±0.87 vs.0.89 ±0.95 for CCR7 mRNA) respectively (all P＜0.05).Conclusions The permeability of vascules in the iris and ciliary body increase during the allograft rejection after penetrating keratoplasty.Increased antigen presenting cells were also detected.

Objective To investigate the effects of early hemofiltration combined with traditional Chinese medicine on nasal feeding on severe acute pancreatitis (SAP) patients. Methods Seventy four patients were divided into traditional Chinese medicine group (group A, 35 cases) and traditional Chinese medicine+hemofiltration group (group B, 39 cases). In group A, patients were given a serious of procedure including fasting, gastrointestinal decompression, fluid resuscitation, inhi-bition of pancreatic secretion, antibiotic prophylaxis, parenteral nutrition and traditional Chinese medicine on nasal feeding;In group B, patients received continuous veno-venous hemofiltration treatment(also called Continuous Renal Replacement Therapy,CRRT) in addition to the procedures receiving by group A. On admission and the first, 3rd, 7th days post-treatment, the scores of acute physiology and chronic health evaluation (APACHEⅡ), tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8) levels were recorded. Length of hospital stay, local and systematic complications, surgical inter-vention, mortality and hospitalization expenses were compared between two groups. Results On admission, no statistical significance was seen in the hematocrit, white blood cell count, lactic acid dehydrogenase, blood urea nitrogen, blood glu-cose, APACHEⅡscore, Ranson’s score and classification of etiology between these two groups (P>0.05). But APACHEⅡ, TNF-α, IL-6, IL-8 were decreased significantly in group B than in group A, after the first, 3rd, 7th days post-treatment (P＜0.05). Compared with group A, the length of hospital stay, local complications, systemic complications, surgical interven-tion, mortality and hospitalization expense were lower in group B. Conclusion Traditional Chinese medicine on nasal feed-ing combined with early hemofiltration could effectively reduce complications, incidence of organ dysfunction and could im-prove the prognosis of SAP patients.

Objective To analyze the serum proteomic pattern of the cervical cancer patients,to develope diagnostic model and to evaluate its clinical significance.Methods WCX magnetic bead and MALDI-TOF were used to detect the serum proteomic pattern of 77 patients with cervical squanmous cell carcinomas,13 patients with CINⅢ and 52 healthy women.Biomarker Wizard software was used to detect protein peaks and potential difference between cervical cancer and controls.The model was developed by Biomarker Patterns software.Results A diagnostic pattern consisting of three differential protein peaks was established with 100%(32/32)sensitivity and 93.8%(30/32)specificity.A sensitivity of 77.8%(35/45)and a specificity of 75%(15/20)in blind test were obtained.The diagnostic model also could discriminate CINⅢ and SCC-Ag negative patients from controls.Conclusion The diagnostic pattern combining 3974,3398,13732m/z protein peaks can discriminate not only cervical squamous cell cancer but also CINⅢ and SCC-Ag negative patients from controls.
