Interpretation of Assessments Recommended in European Physiotherapy Guideline for Parkinson's Disease / 中国康复理论与实践

Rehabilitation is increasingly valued in the field of Parkinson's disease (PD) therapy. European countries issued European Physiotherapy Guideline for Parkinson's Disease in 2014. Based on the analysis of the evaluation method in the guideline, combined with the recent literature and clinical feasibility, this paper mainly analyzed the evaluation tools recommended by the European guidelines for physical therapy of PD, the general requirements for using the recommended evaluation tools and the significance of evaluation, in terms of pre-evaluation tools, evaluation tools to assess the effectiveness of physical therapy, evaluation tools to assess the severity and progression of PD and the evaluation of cognitive psychology.

Bioassay-guided isolation of saikosaponins with agonistic activity on 5-hydroxytryptamine 2C receptor from Bupleurum chinense and their potential use for the treatment of obesity / 中国天然药物

5-Hydroxytryptamine 2C (5-HT) receptor is one of the major targets of anti-obesity agents, due to its role in regulation of appetite. In the present study, the 70% EtOH extract of the roots of Bupleurum chinense was revealed to have agonistic activity on 5-HT receptor, and the subsequent bioassay-guided isolation led to identification of several saikosaponins as the active constituents with 5-HT receptor agonistic activity in vitro and anti-obesity activity in vivo. The new compound, 22-oxosaikosaponin d (1), was determined by extensive spectroscopic analyses (HR-ESI-MS, IR, and 1D and 2D NMR). The primary structure-activity relationship study suggested that the intramolecular ether bond between C-13 and C-28 and the number of sugars at C-3 position were closely related to the 5-HT receptor agonistic activity. Saikosaponin a (3), the main saponin in B. chinense, showed obviously agonistic activity on 5-HT receptor with an EC value of 21.08 ± 0.33 μmol·Lin vitro and could reduce food intake by 39.1% and 69.2%, and weight gain by 13.6% and 16.4%, respectively, at 3.0 and 6.0 mg·kgin vivo. This investigation provided valuable information for the potential use of B. chinense as anti-obesity agent.

Screening situation analysis on pregnant woman toxoplasma gondii infection in 2003-2010 in Shanghai / 上海预防医学

Objective To ascertain the usage of Toxoplasma Gondii(T.gondii) test kit,and analyze the trends of T.gondii infection in Shanghai pregnant women so as to provide scientific evidence for effective intervention measures to prevent congenital toxoplasmosis.Methods The data were collected on methods and results of screening T.gondii infection in pregnant women in Shanghai from 2003 to 2010,and analysis of T.gondii infection was made on pregnant women in this city.Results During 2003 and 2010,in 30 hospitals of the City was carried out the screening test for pregnant women T.Gontii infection.The overall serological positive rate to T.gondii was 1.46% from the 30 hospitals.The positive rates of IgG antibody was 2.46%(1.48%-4.96%) in 277 523 persons,that of IgM antibody was 0.83%(0.38%-1.48%) in 439 868 person.The IgM or both IgG and IgM positive pregnancy cases accounted for 41.74% of the total positive cases which appeared in pregnant women from 2008 to 2010.There were also significant differences in the positive rates among different hospitals so as seasons.ELISA and MEIA were more detected for T.gondii antibody detection,and their detection rates of IgG and IgM were significantly different.Imported kit has higher positive rate of detection T.gondii IgM antibody,but lower positive rate of screening IgG antibody than domestic kit.Conclusion The seroprevalence of T.gondii in pregnant women from 2003 to 2010 were close to the average level investigated in the past in Shanghai,but more attention should be paid to the higher proportion of IgM antibody positive,and stable and reliable test kits should be selected for detecting T.gondii IgG and IgM antibodies to avoid leak and mistaken diagnosis.

Biological characteristics of mesenchymal stem cell and hematopoietic stem cell in the co-culture system / 生理学报

The aim of the present study was to obtain the qualified hematopoietic stem/progenitor cells (HSC/HPC) and human umbilical cord-mesenchymal stem cells (MSC) in vitro in the co-culture system. Cord blood mononuclear cells were separated from umbilical cord blood by Ficoll lymphocyte separation medium, and then CD34HSC was collected by MACS immunomagnetic beads. The selected CD34HSC/HPC and MSC were transferred into culture flask. IMDM culture medium with 15% AB-type cord plasma supplemented with interleukin-3 (IL-3), IL-6, thrombopoietin (TPO), stem cell factor (SCF) and FMS-like tyrosine kinase 3 ligand (Flt-3L) factors were used as the co-culture system for the amplification of HSC/HPC and MSC. The cellular growth status and proliferation on day 6 and 10 after co-culture were observed by using inverted microscope. The percentage of positive expression of CD34 in HSC/HPC, as well as the percentages of positive expressions of CD105, CD90, CD73, CD45, CD34 and HLA-DR in the 4generation MSC, was tested by flow cytometry. Semisolid colony culture was used to test the HSC/HPC colony forming ability. The osteogenic, chondrogenesis and adipogenic ability of the 4generation MSC were assessed. The karyotype analysis of MSC was conducted by colchicines. The results demonstrated that the HSC/HPC of co-culture group showed higher ability of amplification, CFU-GM and higher CD34percentage compared with the control group. The co-cultured MSC maintained the ability to differentiate into bone cells, fat cells and chondrocytes. And the karyotype stability of MSC remained normal. These results reveal that the appropriate co-culture system for MSC and HSC is developed, and via this co-culture system we could gain both two kinds of these cells. The MSCs under the co-culture system maintain the biological characteristics. The CFU-GM ability, cell counting and the flow cytometry results of HSC/HPC under the co-culture system are conform to the criterion, showing that the biological functions of HSC/HPC are maintained.
