Objective To construct the pcDNA3. 1-Brugia malayi (Bm) glyceraldehyde-3-phosphate dehydrogenase (GAPDH) eukaryotic recombinant plasmid and to study its effect on mouse cellular immunity response. Methods Total RNA was prepared from periodic Bm. The target gene fragments were amplified by reverse transcription-polymerase chain reaction (RT-PCR) technique and then were inserted into the cloning vector. pGEM-T Easy, and sub-cloned into pcDNA3. 1. Purified pcDNA 3. 1-BmGAPDH recombinant plasmid and CpG were injected into the anterior tibial muscle of BALB/c mice in order to induce host immunity response. Mice injected with PBS and mice injected with blank plasmid were prepared as controls. The mouse models were immunized for 3 times with an interval of 2 weeks. RT-PCR was utilized to detect target gene expression in the muscle tissue. MTT method was used to measure the immunized mice T lymphocytes stimulation index, while enzyme-linked immunoassay (ELISA) was used to determine the serum interleukin (IL)-4 and interferon (IFN)-γ level. Means were compared using t test with SPSS software. Results The recombinant plasmid pcDNA3. 1-BmGAPDH was constructed sucessfully. The target gene was 1020 bp long and its homology with known gene sequence in database was 99%. BmGAPDH gene in the injected muscle of the immunized mice was detected by PCR. The proliferation of spleen T lymphocytes was higher in pcDNA3-BmGAPDH group than in the 2 control groups which were 1. 398, 1. 006 and 1. 017,respectively (P< 0. 05). The levels of IFN-γ and IL-4 in serums from the immunized mice were significantly higher than those of the PBS control group and blank plasmid control group which were 163.905, 58.589, 51. 317 and 107. 906, 27.111, 34.627, respectively (P<0. 05). Immune adjuvant CpG could accelerate and boost antigen-specific immune responses induced by vaccine, which presented as significant increase of IFN-γ and lymphocyte proliferation at 4 weeks after immunization.Conclusion The recombinant eukaryotic plasmid pcDNA3. 1-BmGAPDH is constructed and could elicit cellular immune responses in immunized mice.

Objective To systematically review the clinical efficacy of botulinum toxin A for the treatment of upper limb spasticity after stroke. Methods PubMed,EMbase,Cochrane Library,CBM, China National Knowledge Internet (CNKI),and Wanfang Data were retrieved by a computer. The randomized controlled trials and Case-control study of comparing botulinum toxin A combined with rehabilitation training and routine rehabilitation treatment for upper limb spasticity after stroke were collected. The retrieval time was from the foundation of the database to September 1,2016. At least two reviewers conducted literature screening,data extraction,and quality evaluation according to the inclusion and exclusion criteria. The Rev-Man 5. 3 software provided by the Cochrane Collaboration was used to conduct the Meta-analysis. Results A total of 356 articles were retrieved. Finally,11 articles met the inclusion criteria. The modified Jadad score showed that the scores of 9 articles were more than 4,which belonged to high-quality literature. Eleven articles included 614 patients,in which 316 were treated with botulinum toxin A. There were 298 patients in the control group. The results of Meta-analysis indicated that the Fugl-Meyer score (SMD =0. 94,95% CI 0. 75 to 1. 12),modified Ashworth score (SMD = - 1. 59,95% CI - 1. 78 to - 1. 40),and modified Barthel index (SMD = 0. 86,95% CI 0. 65 to 1. 08)in the botulinum toxin treatment group were superior to the control group. There were significant differences (all P < 0. 05). The incidence of adverse events (RR = 1. 06,95% CI 0. 78 to 1. 45)was similar in both groups. There was no significant difference (P > 0. 05). Conclusion The efficacy of treatment of upper limb spasticity after stroke with botulinum toxin A is exact,and the security is high. The appropriate rehabilitation training can effectively improve the limb motor function,muscle tension,and quality of life of patients.

The calcaneus bone strength was assessed by quantitative ultrasonography in 47 postmenopausal women with type 2 diabetes mellitus (T2DM group) and 30 healthy postmenopausal women (control group).Speed of sound (SOS),broadband ultrasound attenuation (BUA) and stiffness index (SI) in T2DM patients were (1 015 ± 170)m/s,(84 ± 14) dB/MHz and 45 ± 8,respectively,which were significantly lower than those of control group (1 403 ± 232) m/s,(111 ± 18) dB/MHz and 66 ± 12 (all P < 0.001).Stepwise multiple regression analysis showed that homeostasis model assessment of insulin resistance (IR) was independently correlated with the parameters of quantitative ultrasonography in T2DM patients.The results suggest that calcaneus bone strength is reduced in postmenopausal women with T2DM.

Objective To determine the specific recognition of Echinococcus granulosus (E.g.) cyst fluid crude antigen (EgCF) and antigen B (EgB) by serum specific IgG and IgE using Western blotting during anaphylactic shock induced by E. g. in sheep, and to investigate the importance of defined characteristics and molecular weight of the specific antigens. Methods EgCF was obtained through local slaughterhouses in Urumqi from the cysts of infected sheep liver. Western blotting was used to analyze total specific IgG and IgE antibodies in serum from sheep infected with E.g. using either crude antigen of E. g. and EgB, and to understand specific recognition of hydatid cyst antigens by serum total IgG and specific IgE. Results SDS-PAGE and Western blotting showed that there were differences between EgB and EgCF in electrophoresis pattern. EgB was recognized by IgG from sera of infected sheep in a series of bands with molecular weight ranging from 31, 43 to 66.2 kDa. No binding of IgG against EgCF was observed in any serum from the infected sheep during anaphylactic shock. In contrast, specific IgE antibodies in E. g. infected sheep obviously recognized the single 43 kDa subunit of EgCF, but no binding of specific IgE against EgB was observed in sera of the infected sheep. Conclusion EgCF is consisted of antigenic components in which there is a specific antigen against IgE with a molecular weight of over 43 kDa. This component may lead to an anaphylactic shock induced by E. g. . EgB is a specific antigen against the total IgG but not to the specific IgE.
