Objective To explore the effective communication between therapists and inpatients during rehabilitation treatment. Methods The communication needs were evaluated among 150 inpatients, including stroke and spinal cord injury, following physical dysfunction in 7 aspects to determine the patient's psychological and demand conditions. Then, targeted and effective communication plans were developed and adjusted according to the individual changes of the patients at all stages of the pathogenesis and the patients' feedback information. Finally, the patients' satisfaction surveys were issued when the patients discharged. Results After effective communication was used, 98.5% patients felt satisfied with shortened hospital stay and satisfactory limb function. Compared with the previous patients, effective communication can significantly improve the outcomes and reduce the incidence of doctor-patient disputes. Conclusion Effective communication is helpful for the patients to understand the disease, which can enhance the rehabilitation of compliance and improve rehabilitation outcome.

目的探讨以主动运动为主的社区康复训练对脑卒中恢复后期患者日常生活活动能力的影响。方法将85例社区脑卒中恢复后期患者分为对照组42例和康复组43例。出院后，康复组继续在社区接受以主动运动为主的康复训练，对照组不再进行任何康复训练。结果经过90 d左右，康复组Barthel指数明显提高（P<0.01）。结论以主动运动为主的社区康复训练可提高偏瘫患者的日常生活活动能力。

BACKGROUND:Patients with rheumatoid arthritis have high cardiovascular disease risks and postsurgical complications such as postoperative infection and wound healing problems in the process of total joint arthroplasty. OBJECTIVE:To retrospectively review the peri-operative risks when undergoing total joint replacement in patients with rheumatoid arthritis, and assess these risks, propose solutions to guide clinical practice for better peri-operative management. METHODS:The studies related with perioperative cardiovascular risk, the risk of infection of total joint replacement were retrieved by the first author from PubMed database, GOOGLE academic database, CNKI database, Wanfang database, VIP database from 2000 to 2015 through computer. The key words in English and Chinese were respectively“Rheumatoid arthritis, Total joint arthroplast, Perioperative management, Infection, Postsurgical complications, Corticosteroid, Disease modifying antirheumatic drugs, Biologics”. Old and repetitive studies were excluded. RESULTS AND CONCLUSION:A total of 97 articles were retrieved. Total y 53 articles which content was inconsistent with the research themes were excluded, and 44 papers were included in the analysis. We should make a comprehensive cardiovascular examination for the patients with rheumatoid arthritis before operation. If the cardiovascular disease of the patient is unstable, this condition should be clarified and treated appropriately before surgery, otherwise, patients need to check heart function, and predict the operation risk;We should reasonably arrange the anti-rheumatism medicines and corticosteroid during perioperative, so as to make a balance between reducing postoperative infection and preventing the condition relapse;Because rheumatoid arthritis often easy to erode the cervical spine, we should conduct routine imaging examination for the patients before total joint replacement. Movement should be gentle when general anesthesia was needed.

Nrf2/Keap1/ARE is an important signaling pathway in maintaining the balance between peroxide and antioxidants. Once oxidative stress happened, Nrf2/Keap1/ARE would be ac-tivated to regulate the expression of downstream antioxidant pro-teins that could reduce the injury from oxidative stress and the level of oxidative stress. Recent researches show that Nrf2/Keap1/ARE signaling pathway is closely related to refractory re-spiratory diseases such as pulmonary fibrosis (PF), lung canc-er, chronic obstructive pulmonary disease (COPD), suggesting that Nrf2/Keap1/ARE signaling pathway may be a potential ther-apeutic target. This review focuses on the role of Nrf2/Keap1/ARE signaling pathway in refractory respiratory diseases in order to further understand the related mechanism and provide evidence for the diagnosis and treatment of refractory respiratory diseases.

To eliminate cancer hazards to human health,the development of the therapeutic cancer vaccine has been given more and more attention.By contrast of tradition therapy,cancer immunotherapy take the advantage of being able to achieve target therapy and take modest harm to organism.Here,we first idiscussed the mechanisms of cancer immune escape,and reviewed the design principles of therapeutic cancer vaccine,as well as the latest research progress of therapeutic cancer vaccine and its application.

Objective:To detect the effects of porcelain-fused-to-metal(PFM)crown on the periodontal tissue of the restored teeth,and the relationship between the levels of intedeukin(IL)-1β,aspartate transaminase(AST)and alkaline phosphatase(ALP)in gingival crevicular fluid(GCF)and the health condition of periodontal tissue.Methods:Among 28 patients,34 maxillary incisors with PFM crowns were selected for the study.There were 19 Ni-Cr PFM crowns and 15 Au-Pt PFM crowns.The contralateral homonymy natural teeth were healthy and treated as control teeth.The patients were followed up 6 to 8 months after restoring crowns.The values of IL-1β,AST and ALP in GCF were analysed.Results:The concentrations of IL1β and ALP were significantly higher in GCF of Ni-Cr PFM compared with those of control,whereas no significant difference in Au-Pt PFM group compared with that of control.The level of GCF-AST was higher in Ni-Cr PFM and Au-Pt PFM group than that of healthy control.Conclusion:Ni-Cr PFM crowns have negative influence on periodontal tissue,but Au-Pt PFM have little influence on periodontal tissue of the restored teeth.The activity of IL-1β,AST and ALP of GCF are sensitive to reflect the effect of PFM crowns of different materials on periodontal tissue.

OBJECTIVE:To validate the test condition and test method of the microbil limit test of the Dental ulcer pellicles of Sunset Abelmoschus Flower.METHODS:The methodological validation was carried out in accordance with the standard for microbil limit test stated in the appendix of China Pharmacopoeia(2005 Edition,VolumeⅠ).RESULTS:By membrane-filter procedure,the recovery rates of different test strains in the samples were all over 70%.CONCLUSION:The membrane-filter procedure can more effectively eliminate the bacteriostatic action of Dental ulcer pellicles of Sunset Abelmoschus Flower so as to result in accurate microbil limit test results.

0.1 mV. The rabbits were randomly divided into 4 equal groups of 12 animals in each group: Ⅰ control group in which normal saline 0.2-0.3 ml?kg-1 was injected through epidural catheter; Ⅱ epidural group in which 1% lidocaine 2-3 mg?kg-1 was injected epidurally; Ⅲ propofol group in which propofol was infused iv at 20 mg ? kg-1 ?h-1 for 30 min; Ⅳ combined epidural-propofol group in which epidural 1% lidocaine and propofol iv were both administered. Blood samples were taken before and 4 h, 8 h after ligation for determination of serum concentrations of myocardial troponin I (cTn I ) and MDA and serum SOD activity.The myocardial tissue was taken from the infarct area for determination of the apoptotic myocyte count (TUNEL) and p53 and Bcl-2 protein expressions (LSAB) . Results In control group serum cTn I and MDA increased and SOD decreased significantly after ligation of LAD. Thoracic epidural anesthesia, propofol iv infusion and especially the combination of them suppressed the increase in serum cTn I and MDA and decrease in serum SOD induced by ligation of LAD.In epidural-propofol group and propofol group the apoptotic myocytes count and p53 protein expression significantly decreased, the Bcl-2 protein expression increased as compared with those in control group. Conclusion Thoracic epidural anesthesia combined with propofol can significantly protect myocardium from injury induced by myocardial infarction. This action is mediated by the depression of myocyte apoptosis and the generation of oxygen-derived free radicals.
