Objective To analyze the cost-effectiveness of integrated pharmaceutical care (IPC) in community-based patients with chronic obstructive pulmonary disease (COPD).Methods The COPD patients were divided randomly into intervention group (group A,n =79) and control group (group B,n =71).Group A received the IPC intervention measures,including serial lectures of pharmaceutical knowledge,home supervision and web-based communications for while group B group had none.Results As compared with group B,group A obviously improved on the knowledge of pharmaceutical treatment effect and side effect (95.1％,67.4％ vs.63.1％,21.9％,x2 =12.445,P=0.000 vs.x2 =55.557,P=0.000).There were notable differences between two groups [ ( 1.77 ± 1.23 ) vs.( 2.42 ± 1.66 ) s,t =2.583,P=0.011],pulmonary rales [ (0.01 vs.0.01)s,Z =2.370,P=0.018],6-min walk distance (6 MWD) [ (457 ± 67 ) vs.(425 ± 72) m,t =2.760,P =0.007 ],vital capacity ( VC ) [ ( 1.60 ± 0.25 ) vs.( 1.49 ± 0.23 ) L,t =2.718,P =0.007 ) ] andquality-of-life items ( 48 ± 10 vs.52 ± 11,t =2.624,P =0.010) after intervention.Analyze of cost-effectiveness show that groupA was superior to group B [ total effect total cost(TE/TC =764.6/4936,15.49％ )vs.(TE/TC =1509.4/4708),32.06％,x2 =6.183,P ＜ 0.01 ].Conclusion IPC can improve the disease condition and achieve excellent cost-effectiveness for community-based COPD patients.

Objective To observe changes of cognitive function and the expression of tumor necrosis factor alpha(TNF-α),interleukin 10(IL-10) in hippocampus of diabetic rats,and assess the role of inflammation in the possible pathogenesis of diabetic encephalopathy (DE).Methods 30 male SD rats were randomly divided into control group and diabetes mellitus group.After 4 weeks of feeding high fat diet,diabetes mellitus group according to 30mg/kg injected with streptozotocin to establish type 2 diabetic rat model.At the end of the experiment,cognition were evaluated using water maze test.The concentration of beta-amyloid(Aβ) in hippocampus of diabetic rats were detected through enzyme linked immunosorbent assay,and the expression of TNF-α,IL-10 were detected by Western blotting.The expression of Aβ,TNF-α,IL-10 were observed through immunohistochemistry.Results Time spent in the target quadrant in diabetes mellitus group was shorter than that in control group ((38.21± 3.68)s vs (42.10±2.62)s,t=3.105,P＜0.01).The frequency of crossing original platform site was less than that in control group((2.62±0.77) vs(3.69±0.95),t=3.184,P＜0.01).Compared with control group the expression of Aβ,TNF-α were higher(BothP＜0.01),and IL-10 were lower(P＜0.01)in diabetes mellitus group.The positive expression of Aβ,TNF-α were obviously and IL-10 were less obviously observed in diabetes mellitus group according to immunohistochemistry.Conclusion The cognitive decline in diabetic rats is possibly related to inflammatory cytokines expressing out of balance.

Objective:The recombinant human retinal pigment epithelium-derived factor(PEDF)protein to be obtained and the angiogenesis of the rPEDF to be identified.Methods: PEDF gene gene was amplified by PCR and cloned into pET32a,rPEDF protein was expressed in E.coli BL21 and confirmed by SDS-PAGE and Western blot.The rPEDF was purified by Ni-NTA on denature condition.The concentration of the rPEDF was determined by Bradford method.The angiogenesis of the rPEDF was determined by chick chorioallantoic membrane(CAM) method.Results: The expression plasmid pET32a-PEDF was constructed successfully.The rPEDF was expressed with stable efficiency in E.coli BL21.The results of the CAM experiment showed that the rPEDF had notable angiogenesis effect in the concentration 0.4、0.04 ng/ml,but had no effect in 4 ng/ml.Conclusion:The PEDF gene was cloned and expressed efficiently,the angiogenesis of the rPEDF to be identified and the activity was worked in certain range.The results can facilitate studying its function and spreading its application.

Objective To discover radioresistance associated molecular biomarkers and its mechanism in nasopharyngeal carcinoma by protein-protein interaction network analysis.Methods Whole genome expression microarray was applied to screen out differentially expressed genes in two cell lines CNE- 2R and CNE-2 with different radiosensitivity.Four differentially expressed genes were randomly selected for further verification by the semi-quantitative RT-PCR analysis with self-designed primers. The common differentially expressed genes from two experiments were analyzed with the SNOW online database in order to find out the central node related to the biomarkers of nasopharyngeal carcinoma radioresistance. The expression of STAT1 in CNE-2R and CNE-2 cells was measured by Western blot.Results Compared with CNE-2 cells,374 genes in CNE-2R cells were differentially expressed while 197 genes showed significant differences.Four randomly selected differentially expressed genes were verified by RT-PCR and had same change trend in consistent with the results of chip assay. Analysis with the SNOW database demonstrated that those 197 genes could form a complicated interaction network where STAT1 and JUN might be two key nodes.Indeed,the STAT1-α expression in CNE-2R was higher than that in CNE-2 (t =4.96,P ＜ 0.05).Conclusions The key nodes of STAT1 and JUN may be the molecular biomarkers leading to radioresistance in nasopharyngeal carcinoma,and STAT1-α might have close relationship with radioresistance.

Objective To explore the adjustment effects of suckling nutrition on hypothalamus gonadotropin-releasing hormone neurons(GnRH) expression level and adolescence sexual development by establishing different nutrition models for suckling female rats.Methods One-day-old female Sprague-Dawley rats were randomly assigned to 3 groups.Two suckling rats were fed by one lactation rat in overnutrition group,10 suckling rats were fed by one lactation rat in normal control group,20 suckling rats were fed by one lactation rat in malnutrition group.The animals were weaned at day 21 of age in groups of 5 rats per cage with free access to pelleted food and tap water.To comparatively observe vaginal opening,10 rats in each group were randomly sacrificed when the overnutrition rats showed complete vaginal opening and when the normal control rats showed complete vaginal opening.The amount and percentage of the positive GnRH neurons in hypothalamus arcuate nucleus were detected with immunohistochemistry.The influence of suckling nutrition to female rats adolescence sexual development was assessed by statistical analysis.Results 1.When the overnutrition rats showed complete vaginal opening(at 35-day-old),the amount of positive GnRH neuron in hypothalamus arcuate nucleus was respectively 247?111 in overnutrition group,143?73 in normal control group and 74?70 in malnutrition group.It was showed that the amount of the positive GnRH neuron of hypothalamus arcuate nucleus in overnutrition group was more than the other groups(Pa0.05).3.Overnutrition female rats showed complete vaginal opening at a mean age of (29.60?1.96) days,(39.10?1.66) days in normal control female rats and (41.30?3.33) days in malnutrition female rats.It was proposed that the sexual development of overnutrition rats was earlier than the other groups(Pa
