Methods 120 patients with pathologically confirmed esophageal cancer were included in the study.Zung depression status inventory (DSI)and hamilton depression rating scale (HAMD)were used to assess depression.Serum sTNFR-1,sIL-2Ra and IGF-1were detected by enzyme-linked immunosorbent assay (ELISA).Results 69 patients were classified as anxiety and depression group,51 patients were as normal control group.There were 32 patients with depression.Serum sTNFR-1, sIL-2Ra and IGF-1 levels in study group was higher than that in the control group (P<0.05)and these serological indexs increased from the minimal depression,mild-to-moderate depression group to severe depression group (P<0.05).Conclusion Serum sTNFR-1,sIL-2Ra and IGF-1 levels may be used as evaluation index of nursing intervention,but need further clini-cal validation.

Objective: To explore the particularity of high school students’ problem behaviors with three-perspective analysis. Methods: Students,parents and teachers were tested by High School Students’ Problem Behavior Questionnaire based on item analysis of open-ended investigation. Results: ①Concerning the identification of problem behaviors,the behaviors such as taking drugs,committing suicide,and stealing got higher scores by students’ self-rating; the behaviors such as running away from home,stealing,and intimidating got higher scores by parent-rating; and the behaviors such as cheating,learning without motivation or objective,and bad learning habits got higher scores by teacher-rating. ②Students,parents and teachers all agreed on the following high frequency problem behaviors; worrying about scores,rarely doing housework,concentration deficits and bad learning habits. ③The frequencies of problem behaviors reported by students were higher than those by their parents. Conclusion: There are significant differences in the identification of problem behaviors among students,parents and teachers,however,the three parts have similar views on the most common problem behaviors.

Objective To explore the correlation between polymorphism of interleukin-28B(IL-28B) rs12979860 T/ C and susceptibility of hepatocellular carcinoma( HCC). Methods All eligible case-control studies published up to 2014-09-30 were identified by searching PubMed,EMBase,CNKI,CBM,VIP and WanFang databases. Two reviews independently identified the literature according to inclusion and exclusion criteria. Meta-analysis was performed using Rev Man 5. 2 and Stata 12. 0 software. Results A total of 6 stud-ies comprising 1 138 cases and 955 controls were finally included. Meta-analysis showed that IL-28B rs12979860 T/ C polymorphism was associated with the susceptibility of HCC. Compared with the genotype CC and CT + CC,genotype TT increased the risk of suffering from HCC(TT vs CC:OR = 2. 26,95% CI:1. 40-3. 64,Z = 3. 33,P = 0. 000 9;TT vs CT + CC:OR = 1. 90,95% CI:1. 23-2. 93,Z = 2. 89,P = 0. 004). In stratification analysis by ethnicity,we observed that the polymorphism of IL-28B rs12979860 T/ C was associat-ed with the susceptibility of HCC among Caucasian populations(TT vs CC:OR = 2. 06,95% CI:1. 22-3. 47, Z = 2. 70,P = 0. 007;TT vs CT + CC:OR = 1. 71,95% CI:1. 07-2. 72,Z = 2. 23,P = 0. 03). Conclusion The polymorphism of IL-28B rs12979860 T/ C is associated with the susceptibility of HCC,genotype TT may increase the susceptibility to HCC.

To study the angiogenic activity of amphoteric brush-type copolymer complex of alginate-graft-PEI/pVEGF (Alg-g-PEI/pVEGF) in vivo, we evaluated the toxicity of Alg-g-PEI/pVEGF complexes to rMSCs and zebra fish first. Then, we used gel retardation assay to investigate the protection of complex to pDNA against DNase I, serum and heparin. For in vivo study, we evaluated the angiogenic activity of Alg-g-PEI/pVEGF complexes by using CAM and zebra fish as animal models, PEI 25K/pVEGF and saline as positive and negative controls. Our results show that Alg-g-PEI protected pVEGF from enzymolysis and displacement of heparin in some degree, and its complexes with pVEGF were less toxic to rMSCs and zebra fish. Alg-g-PEI/pVEGF complexes induced significant angiogenesis, which was dosage-dependent. In CAM, when the dosage of pVEGF was 2.4 microg/CAM, Alg-g-PEI group achieved the maximum of angiogenesis, and the area ratio of vessel to the total surface was 44.04%, which is higher than PEI 25K group (35.90%) and saline group (24.03%) (**P < 0.01). In zebra fish, the angiogenesis increased with the increase of N/P ratios of Alg-g-PEI/pVEGF complexes in our studied range; when N/P ratio was 110, the optimal angiogenesis was obtained with vessel length of 1.11 mm and area of 1.70 x 10(3) pixels, which is higher than saline group (0.69 mm and 0.94 x 10(3) pixels) (**P < 0.01) and PEI 25k group (0.82 mm and 1.11 x 10(3) pixels) (**P < 0.01). Our results demonstratethat Alg-g-PEI/pVEGF significantly induces angiogenesis in CAM and zebra fish, and has a great potential in therapeutic angiogenesis.

Objective To investigate the therapeutic effect of a combination of artemether and daphnetin against Plasmodium berghei ANKA strain in mice. Methods Groups of P. berghei infected mice were treated with various oral doses of artemether and daphnetin according to “4-day suppress assay”. Thin blood smears were made on the fifth day after inoculation of parasites and the parasitemia reduction rate was calculated. The ED 50 values obtained were plotted on isobolograms. A combined action of artemether and daphnetin was assessed. Results Artemether 0.4mg/(kg?d)?4d exhibited no detectable antimalarial effect, while artemether 0.4mg/(kg?d)?4d combined with daphnetin 7.7 mg/kg.d?4d showed potent antiparasile efficacy. The ED 50s of artemether in combination with daphnetin were lower than that of single artemether or daphnetin. The R-values were higher than 0.4, but lower than 2.7. Conclusion The combination of artemether with daphnetin showed an additive antiparasile effect.

Objective:To explore whether apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin can be cross-presented by dendritic cells(DCs) and enhance immune responses.Methods:DCs were induced from peripheral blood monocytes cells by GM-CSF/IL-4 for 6 d,then they were stimulated with either apoptotic ovarian cancer HO8910 cells,frozen-thawed HO8910 cells or control cells for 4 h.Their surface markers and phagocytotic ability were detected by flow cytometry and confocal microscopic scanning assay,respectively.DCs of different groups were cultured with CD8+ T cells isolated by magnetic cell sorting,and the ability of DCs to activate CD8+ T cells was evaluated by 3H-TdR,the activity of CTL to kill tumor cells was evaluated by LDH.Production of IFN-? by CD8+ T cells was measured by ELISPOT.Results:Apoptotic ovarian cancer cells induced by chemotherapy drugs paclitaxel and cisplatin could be phagocytized by DCs,which subsequently promoted the maturation and antigen presenting ability of DCs.Apoptotic ovarian cancer cells implused DCs significantly promoted proliferation of CD8+ T cells compared with that of control cells(P
