This study investigated the effect evaluation and safety of electroacupuncture combined with balloon dilatation on dysphagia after cerebral infarction. Methods: Totally 100 patients with dysphagia after cerebral infarction were enrolled as study subjects and assigned into the control group (treated with balloon dilatation) and the observation group (treated with electroacupuncture and balloon dilatation), with 50 cases in each group. The general data of participants were recorded. Before or after treatment, swallowing function was assessed by water swallow test, standardized swallowing function assessment (SSA), videofluoroscopic swallow study (VFSS), and functional oral intake scale (FOIS). The cerebral hemodynamics, serological indicators, neurological impairment, quality of life (QOL) score were analyzed. Additionally, the occurrence of complications and adverse reactions after treatment was assessed. Results: There was no significant difference in gender, age, BMI, course of disease, and grade of dysphagia between the two groups. Balloon dilatation alone and electroacupuncture combined with balloon dilatation decreased the water swallow test, SSA, and VFSS scores, increased FOIS score, and improved the swallowing function, cerebral hemodynamic parameters, serological indicators, neurological function and QOL, with the better efficacy in the combined therapy. Moreover, combined therapy had lower incidences of complications and adverse reactions than balloon dilatation therapy alone. Conclusion: Electroacupuncture intervention combined with balloon dilatation therapy ameliorates swallowing function, cerebral hemodynamics, serological indicators, neurological function and QOL, and reduces complications and adverse reactions in dysphagia after cerebral infarction.展开更多

In order to the overexpression of the target protein in wild type strains, we choose PYEs2.0 as the original carrier, the acyl-coA binding protein (ACBP) and GFP gene have been cloned in the multiple cloning site. The screening of labeled URA3 gene was replaced by KanMX gene which anti G418. The vector was obtained through the screening of G418 at the concentration of 25 ug/ml.展开更多

The purposes of this study were to determine and evaluate the biological activities for the commercialization of recombinant follicle-stimulating hormone (rFSH) in vitro through the cellular internalization using cloned 293T-FSHR cell lines as target. Using imaging approaches we have found here that a little fluorescent signal from the surface of the cell transferred to the cytoplasm and accumulated around the nucleus by endocytosis. Compared with the control groups, the commercialization of rFSH have not the significant differences of internalization, but the rFSH have promoted the internalization of the fluorescent, suggested that this detection system might as a protocol for the bioactivity of recombinant therapeutic proteins in vitro.展开更多

Follicle stimulating hormone receptor (FSHR) is a kind of G protein coupled receptor (GPCR), found in the ovary and testes, and its activation is required for the hormonal operation during the breeding period. In this study, an experimental model of FSHR mediated FSH into cell membrane, which exhibited a phenomenon of fluorescent localized on cell surfaces internalized into cell interior, was established to verify biological activity of FSH.展开更多
