ABSTRACT
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 .
ABSTRACT
Objective To explore the clinical significance of thyroid hormones test using in diabetes mellitus (DM).Methods 98 cases with DM and 40 health people were selected.The serum T3,T4,FT3,FT4,TSH,rT3 levels were tested to analy the relativity of DM and TH.Results The type 2 DM's and type 1 DM's T3,T4,FT3,FT4 levels were much lower than those of the control group,while the rT3 level was higher(P ＜ 0.05 ) ;and the type 1 DM was the lowest one(P ＜0.05).In group 7％ ～ 10％,Group ＞ 10％ ～13％ and Group HbA1c ＞ 13％ T3,FT3 and TSH levels were lower than Group HbA1c ＜ 7％ (P ＜ 0.05 ).With DM extension,FT3 and T3 declined,while rT3 ascended (P ＜0.05 ).Conclusion DM patients are always with the abnormal of TH level,so monitoring the TH level is importantfor evaluating the DM patients' state and course.
ABSTRACT
Objective To construct eukaryotic expression plasmid of human B7-H1 extracellular region-hIgG1Fc-pCI-neo eukaryotic expression vector,and express the functional fusion protein in mammalian CHO cell.Methods Full-length human B7-H1 encoding sequence was amplified from human activated T cell cDNA library by PCR,fused with hIgG1Fc,then transformed into pCI-neo expression vector and verified by sequencing.The validated recombinant was transfected into mammalian CHO cell by lipofectamine reagent.The supernatant of the cultured cell was collected and analyzed by the sandwhich ELISA to detect if there was the fusion protein,and the fusion protein was purified by HiTrap recombination protein Protein A affinity chromatography.The concentrated supernatant or purified fusion protein were used for Western blotting after SDS-PAGE to identify the molecular weight and immune activity of the fusion protein of B7-H1.Results The extracellular region of hB7-H1 about 727 bp was cloned from human T cell cDNA library and was inserted with hIgG1Fc into the eukaryotic expression vector pCI-neo.After the transfection of recombinant into mammalian CHO cell by lipofectamine reagent,the expression of B7-H1 fusion protein was detected in the cultured CHO cell supernatant by the sandwhich ELISA.The immune activity of the fusion protein was verified by Western blotting,and its molecular weight was about 51.76?10~(3),very close to the expected value.Conclusion The hB7-H1-Fc chimeric molecule was successfully constructed and the expression of its functional fusion protein in mammalian CHO cells lays a foundation for further research on the role of B7-H1 in immune tolerance,autoimmune diseases.
ABSTRACT
Objective To study the effect of Tibet medicine of Herba Lamiophlomis rotata on promoting hemostasis and blood coagulation and to explore its mechanism. Methods High dose(2 g/kg),middle dose(1 g/kg) and low dose (0.5 g/kg) of the aqueous extract from Herba Lamiophlomis rotata(HLRE)were given to mice by gastric gavage for 3 days,and then bleeding time (BT),clotting time(CT) and platelet count(PLC)were determined. Different doses of HLRE(3,1.5,0.75 g/kg)were administered by gastric gavage to rats for 14 days,and then blood samples were collected from common carotid artery for the determination of prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time(TT),fibrinogen(FIB),hepatic function and blood lipid indexes. Results Compared to the blank control group,the bleeding time and clotting time were obviously shortened in 2g/kg HLRE and 1g/kg HLRE groups and positive control group,but the difference of PLC was insignificant. PT and APTT values in all of the treatment groups did not differ from those in the blank control group. However, TT values were obviously shortened in 3 g/kg HLRE group,FIB and Albumen(Alb)values increased,the aminotransferase and blood lipid values tended to decrease. Conclusion The aqueous extract from Herba Lamiophlomis rotata has an effect on promoting hemostasis and blood coagulation ,and its mechanisms may be related to the increase of FIB and Alb contents and the shortening of TT value.
