RESUMO
Objective To investigate the effect of Yunnan Baiyao Plaster on serum related markers levels in the patients with stroke ,to evaluate its improvement effect on the neurological dysfunction and pain and to analyze its effect mechanism .Methods Eighty cases of hemorrhagic stroke treated in the neurosurgical department of our hospital from February 2015 to June 2016 were screened as the research subjects and divided into the control group and observation group according to the random number table method ,40 cases in each group .All subjects were given the routine treatment ,while the observation group received the external use of Yunnan Baiyao Plaster around the head operative incision and drilling ,to give Yunnan white ointment ,with the attaching area of 5 cm × 4 cm ,once daily ,for consecutive 7 d ,meanwhile took oral Yunnan Baiyao Plaster 0 .5 g with warm boiling water ,once daily for consecutive 7 d .The serum markers levels before and after treatment ,neural function defect score ,decline proportion of NIHSS scores and prognostic indicators were compared between the two groups .Results The mean pain value within 1 week in the obser-vation group was lower than that in the control group ,the difference was statistically significant (P 0 .05);after 2 weeks ,ET ,TNF-α and IL-1β levels in the observation group and control group were lower than those before treatment in the intra-group comparison ,while the comparison between the two groups showed that the ob-servation group was lower than the control group ,the difference was statistically significant (P0 .05) .Conclusion The combined treatment of Yunnan Baiyao Plaster in the patients with hemorrhagic stroke conld relieve pain and reduce the neurological deficit ,which might be related to the mechanism of anti-inflammation and analgesia .
RESUMO
To establish human beta-defensin-3 gene transgenic cell lines as competent donor cells for the production of transgenic animals using somatic cell nuclear transfer (SCNT). Firstly, we obtained human beta-defensin-3 by RT-PCR from human placenta, and subsequently inserted the fragment hBD into the corresponding site of the plasmid pBCP. Then we moved the combined fragment BCD (including 5' and 3' regulating region of beta-casein and hBD) into the corresponding site of the plasmid pEGFP-C1. Finally we successfully constructed mammary-specific expression vector pEBCD. We transected pEBCD into Holstein Fetal fibroblast cells by Lipofectamine TM-2000 and selected in medium with G418 for three to four weeks. We identified G418 resistant transfectants by PCR, RT-PCR and EGFP detection. Our results indicated that human beta-defensin-3 gene stably was integrated into the open region of the chromatin in G418 resistant fibroblast cells. Meanwhile we identified the expression of human beta-defensin-3 in the supernatant of stable transfected mammary epithelial cells by Western blotting. This study may provide competent transgenic donor cells for the production of transgenic animals by SCNT and improve the efficiency of transgenic cloning.
