Objective:To explore the effects the of Astragalus Polysaccharide on specific immune therapy in a mouse model of asthma.Methods:Ninety SPF(Specific pathogen Free) BALB/c mice were randomly divided into six groups.The experimental groups were sensitized with OVA,treated with SIT or APS or their joint application.Then the mice were excited with 1% OVA.24 hours after the last excition,the numbers of the total inflammation cells and esoinophils(EOS) in BALF were counted.The left lung tissues were used to perform histological analysis.IFN-γ and IL-4 in peripheral blood were analysed by ELISA.Results:After the therapy,asthma-associated lung inflammation was inhibited,and the numbers of total cells and EOS decreased.IFN-γ level was raised and IL-4 level was lowered.Conclusion:APS can enhance SIT.It may result from affecting production of both the IFN-γ and IL-4.

Objective To investigate the effect of transcranial direct current stimulation combined with motor relearning program on the recovery of upper limb motor function after stroke.Methods From September 2015 to June 2016,40 patients with first-ever stroke received rehabilitation therapy at the Department of Rehabilitation Medicine,Xuanwu Hospital,Capital Medical University were enrolled prospectively.Their course of disease was 1 to 6 months.They were divided into either a combined treatment group or a control group according to the odd and even numbers in hospital (n =20 in each group).The patients of both groups received traditional rehabilitation training and motor relearning program for upper lindb recovery,2 times a day,once for 30 min,5 days a week for 6 weeks.The combined treatment group was also given transcranial direct current stimulation,2 times a day,once for 20 min,5 days a week,while the control group was only treated with sham stimulation treatment.The patients were assessed before treatment and at 6 weeks after treatment.Fugl-Meyer Assessment (FMA) scores and Action Research Arm Test (ARAT) were used to assess upper limb motor function.The modified Barthel index (MBI) was used to evaluate the activities of daily living.Results There was no significant difference in the observation indices before treatment between the 2 groups (P ＞ 0.05).Six weeks after treatment,the differences of the upper limb FMA score and ARAT score before treatment were superior to the control group,they were 13 ± 3,10 ± 3 and 10 ± 2,8 ± 2,respectively (t =3.503 and 3.244 respectively,all P ＜ 0.01).There was no significant difference in the MBI score between the 2 groups (P ＞ 0.05).Conclusion Transcranial direct current stimulation combined with motor relearning program may effectively improve the upper limb motor function in patients with stroke and promote the improvement of the activities of daily living.

Objective To investigate the effect of lower limb rehabilitation training robot combined with task-oriented training on walking ability after stroke. Methods From February 2014 to August 2015,74 consecutive patients with post-stroke who received rehabilitation therapy and met the inclusion criteria admitted to the Department of Rehabilitation Medicine,Xuanwu Hospital,Capital Medical University were collected prospectively. They were all the patients with the first-ever stroke for 1 to 12 months. They were divided into either an observation group (n = 39)or a control group (n = 35)according to whether they were treated with the lower-limb rehabilitation robot. The patients of both groups received task-oriented training,2 times a day,once for 20 min,5 days a week for 12 weeks. The observation group was also treated with the lower-limb rehabilitation training robot,1 time a day,once for 30 min,5 days a week. Berg balance scale,Fugl-Meyer assessment (FMA),timed up-and-go test (TUG)and knee flexion active range of motion (KFAROM)were used to assess the efficacy. Results (1)After treatment,the Berg scale and FMA scale scores were increased in the observation group and the control group compared with before treatment. There was significant difference (Berg scale:28 ±9 vs. 22 ±9,29 ±9 vs. 24 ±9;FMA scores:47 ± 8 vs. 36 ± 8,40 ± 6 vs. 36 ± 7;all P < 0. 01),however,there was no significant difference between the two groups (P <0. 05),and there was significant difference in FMA scores between the 2 groups (P < 0. 01 ). The differences of Berg scale scores in the observation group and the control group were 10. 75 + 0. 30 and 4. 71 + 0. 14 respectively before and after treatment. There was no significant difference between the 2 groups (t = 0. 95,P = 0. 345). The differences of FMA scores in the observation group and the control group were 5. 8 ±0. 6 and 4. 9 ±0. 8 before and after treatment (t =5. 16,P <0. 01). (2)After treatment,the tug test and KFAROM of the observation group and the control group were better than those before treatment. There were significant differences (TUG test:35 ± 13 s vs. 56 ± 18 s,53 ± 17 s vs. 58 ± 18 s;KFAROM:82 ± 24° vs. 60 ± 23°,63 ± 23° vs. 57 ± 26°;all P < 0. 01),and there were significant differences between the 2 groups (all P < 0. 01). The differences of the TUG test in the observation group and the control group before and after treatment were 21. 5 ± 5. 0 and 4. 6 ± 0. 6 s respectively. There was significant difference between the 2 groups (t = 9. 55,P < 0. 01);the differences of KFAROM in the observation group and control group before and after treatment were 5.8 ±0.6° vs. 4.9 ±0.8° respectively. There was significant differences between the 2groups (t =4.17,P <0. .01). Conclusion Lower limb rehabilitation training robot combined with task-oriented training may improve the lower extremity motor function,walking ability,knee flexion joint activity of the patients after stroke,but the improvement effect of the lower limb balance is not obvious.

BACKGROUND: Changes of elastic fibers in middle cerebral artery(MCA)is close related withthe aged cerebrovascular disease.OBJECTIVE: To observe the changes of elastic fibers of MCA in different aging rats.DESIGN: A descriptive and controlled study based on experimental animals.SETTING: Department of anatomy and central laboratory in a university.MATERIALS: Totally 36 healthy Wistar rats with either gender, weighing 200 - 280 g, were selected from the Animal Institute of the third medical military university of Chongqing[certification SCXX (army) 2002-007].INTERVENTIONS: Changes of elastic fibers of MCA of different aging rats were observed with light microscope, transmission electron microscope and image analysis system. MAIN OUTCOME MEASURES: ①) Major outcome: changes of elastic lamella in MCA of different aging rats; ②) Secondary outcome: ultramicrostructural changes of internal lamella under the transmission electron microscope. RESULTS: With the increase of age, the folded extent and quantity of internal elastic lamella were decreased, and the content of elastic fibers were also decreased significantly( P ＜ 0.01 ). However, the ratio of collagen fibers to elastic fibers was increased significantly( P ＜ 0.01 ) . In the aging group above 24 months, the internal elastic lamina thinned, delaminated and disrupted, and the lipid deposited in it. Endothelial cells and smooth muscle cells passed through the internal elastic lamina. CONCLUSION: Changes of elastic fibers may be related with the increased susceptibility to the cerebrovascular disease in aged people.
