Aim: To investigate the enhancement of enhancers on matrine in vitro and in vivo. Methods: The permeability of matrine across rat intestine was determined by non-everted intestinal sacs model in vitro, and the in vivo activity was assayed in a model of acute liver injury in mice. Sodium deoxycholate (SDC) was selected as the enhancer Candidate. Results: Among the tested absorption enhancers, only polysorbate 80 (Tween 80) and SDC showed to be capable of increasing the transport of matrine through small intestinal mucosa in rats.Enhancement ratios of 1.6 was observed for 0.5% SDC solutions with the best absorption enhancement for matrine in vitro, it was chosen to conduct hepatoprotective study in vivo. In mice with acute liver injury, combination of matrine with 0.5% SDC demonstrated considerably more activity than matrine along after oral administration. Conclusion: The results indicated that the absorption of matrine could be significantly improved by the absorption enhancer.

A novel method was developed for the determination of the 15+1 European priority polycyclic aromatic hydrocarbons in edible oil by online solid-phase extraction coupled with high performance liquid chromatography-ultraviolet/ fluorescence detection ( online-SPE-HPLC-UV/FL-D ) . The edible oil samples were diluted with isopropyl alcohol, and then filtered. The online extraction was performed on a solid phase extraction ChromSpher Pi column (80 mmí3 mm) and the separation was carried out on a C18 reversed-phase PAH column (250 mmí4. 6 mm i. d, 5μm) using ultraviolet detection at 220 nm and fluorescence detection. Isopropyl alcohol, acetonitrile and water were served as mobile phase in gradient elution. The results showed good linearity for the 15+1 polycyclic aromatic hydrocarbons with all the correlation coefficients (R2)>0. 99. The limits of detection ( LODs ) were between 0. 03 and 12. 23 μg/kg. The recoveries of the sixteen components in the three levels of spiked samples were in the range of 65 . 3%-110 . 5% with the relative standard deviation (RSD, n=6) from 0. 1% to 9. 8%.

Objective:To explore the application and nursing of protein A immunosorbent in patients with neuromyelitis optica spectrum diseases.Methods:Ten patients with neuromyelitis optica spectrum diseases were treated with protein A immunoadsorption therapy. Psychological nursing was emphasized. Comprehensive evaluation was conducted before adsorption to determine the prescription of adsorption therapy. During adsorption therapy, hypotension, membrane rupture and hemolysis of plasma separator, shivering and other adverse reactions were accurately prevented and treated. After treatment, attention should be paid to the prevention of nosocomial infection, regeneration and preservation of adsorption column.Results:After immunoadsorption therapy, the serum IgG level, antibody and EDSS score of 10 patients decreased to varying degrees. The serum IgG decreased from (6.04±2.77)g/L to (2.23±1.74)g/L. No serious complications occurred, no failure of immunosorbent operation, and the patients′ condition was better than before.Conclusions:Protein A immunosorbent therapy for neuromyelitis optica spectrum diseases is safe and effective. Standardized evaluation, operation and nursing are the key to achieve good results.

Objective To investigate the life quality of parents of asthma children as well as the influencing factors? Method Totally 125 parents of children with asthma from three different communities in Guangzhou were involved in the survey by the Chinese Paediatric Asthma Caregiver’s Quality of Life Questionnaire (PACQLQ) and demographic questionnaire? Results The total score on PACQLQ was(4?34±1?03): the scores on dimentions of limited motion and affection were(4?29±1?55)and(4?36±0?89),respectively?The major factors influencing the life quality of their parents included the relationship with them and their disease course? Conclusions The life quality of their parents reaches the lowest level at the beginning of confirmed diagnosis of asthma? The health education should be performed right after confirmed diagnosis? During health education,their mental stress is worth our great attention?

Objective To explore the expression of cyclooxygenase-2 (COX-2) in different epidermal tumors and its significance. Method The expression of COX-2 was detected by immunohistochemical staining of skin specimens from 10 cases of basal cell carcinoma (BCC), 8 squamous cell carcinoma (SCC), 8 Bowen′s disease (BD), 12 seborrheic keratosis (SK) and 10 normal volunteers. Results Compared with normal epidermal cells, COX-2 expression was significantly increased in BCC, SCC and BD cells. Especially, COX-2 expression in SCC was the most intensive. COX-2 expression in SK cells was similar to that of normal epidermal cells. Conclusion The up-regulation of COX-2 expression may play a potential role in the pathogenesis of epidermal tumors.

Objective To investigate the expressions of Wnt2 and β-catenin in Doxorubicin (DOX)-induced myocardial injury and to explore their roles in myocardial cell apoptosis.Methods Cardiomyoblast cells were damaged by different concentrations of DOX(1 mg/L,2 mg/L,3 mg/L,4 mg/L) for 72 h.The effect of different concentrations of DOX on cardiomyocyte growth curve was detected according to the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-h-tetrazolium bromide(MTT) assay.DOX(1 mg/L) was used to induce the model of cardiomyoblast cell injury.Cardiomyocytes were divided into 4 groups:group A:DOX-injured cardiomyocytes for 12 h ;group B:DOX-injured cardiomyocytes for 24 h ; group C:DOX-injured cardiomyocytes for 48 h; group D:normal cardiomyocytes.The expressions of Wnt2,β-catenin and p53 were observed by Western blot and reverse transcription polymerase chain reaction(RT-PCR) at the time point of 12 h,24 h and 48 h.Results DOX significantly inhibited cardiomyocyte proliferation in a dose dependent fashion.The protein and mRNA expressions of Wnt2 increased in the DOX-induced myocardial injury group compared with the group D,with statistical significance (F =224.115,P < 0.05) ;The expressions of β-catenin,p53 were significantly increased compared with the group D,and the higher expression appeared with the time extending(F =188.145,231.927,all P < 0.05).Significantly positive correlation between Wnt2 and β-catenin expression was observed(r =0.940,P < 0.05).Conclusions These findings suggest that Wnt2/β-catenin signaling pathway may play important roles in the cardiovascular disease and be useful for exploring the molecular mechanism of myocardial injury..

ObjectiveTo observe the effect of Astragalus membranaous on angiotensinⅡ (AngⅡ)-induced transform-ing growth factor β1 (TGF-β1) production of cardiac ifbroblasts.Methods Cardiac ifbroblasts were culturedin vitro. Cells were allocated into 3 groups: control group, Astragalus membranaous groups (50, 100, 200 mg/ml), Ang II group (10-7 mol/L) and AngⅡ/Astragalus membranaous groups (50, 100, 200 mg/ml). The proliferation of each group was tested by methyl thiazolyl tetrazolium method. TGF-β1 was measured by ELISA.Results The proliferation of cardiac ifbroblasts had signiifcant difference between each groups (F=71.84,P=0.000). The proliferation of cardiac ifbroblasts with Ang II stimulation was higher than that of cells without Ang II stimulation (P<0.05). Astragalus membranaous inhibited Ang II-induced cardiac ifbroblasts proliferation dose dependently (P<0.05). The TGF-β1 production had signiifcant difference between each groups (F=786.81,P=0.000). The TGF-β1 production in AngII/astragalus membranaous groups was lower than that in Ang II group (P<0.05). The TGF-β1 production in Ang II group was the highest, and had signiifcant difference as compared to other groups (P<0.05). Astragalus membranaous inhibited Ang II-induced TGF-β1 production dose dependently (P<0.05).Conclusions Ang II can stimulate the proliferation of cardiac ifbroblasts, and promote the TGF-β1 production. Astragalus membranaous can inhibit the proliferation of Ang II-induced cardiac ifbroblasts, and reduce the TGF-β1 production of cardiac ifbroblasts.
