Objective To know the self-perceived burden (SPB) of young and middle-aged patients with first-attack of ischemic stroke and to analyze the influential factors of SPB as well as its relevance to the quality of life.Methods The patients' general information questionnaire,SPB Self-evaluation Scale,QOL-BREF were adopted to investigate young and middle-aged patients with first-attack of ischemic stroke.Results 100 patients were included,66 were male,34 were female.The Minimum age was 19.4 years old.The maximum age was 59 years old.The mean age was (50.80 ± 7.98) years old.The average SPB score was (24.21 ± 7.39) points,which was in the medium level.31 cases (31％) didn't have obvious SPB; 65 cases (65％) suffered mild-to-moderate SPB; 4 cases (4％) claimed they had severe SPB.There was negative correlation between the SPB and their quality of life.The multi-factor analysis showed that gender,the patients' understanding of disease,and caregivers' health situation were the influential factors of SPB.Conclusions Since self-perceived burden is common in young and middle-aged patients with ischemic stroke,clinical nurses should assess patients' self-perceived burden so as to provide targeted nursing intervention and health education,thereby to ease the burden on patients' self feeling,eventually to improve the level of their mental and physical health.

Objective To investigate the correlation between ultrasonographie classification, age and lesion in female. Methods One thousand two hundred and eight patients with 2416 mammary gland were comfired by pathologic findings, including 132 benign lesion and 54 malignancy lesion. According various sonographic appearances in the mammary gland structure and involution grade, the mammary glonds were classified into glandular,fibroglandular and fatty types. A single mammary gland is statistic unit. Results To follow age growth, the proportion of glandular type was decrease, 61.7% in under 30 years of age,31.5% in 30-39 years of age,15.3% in 40-49 years of age,8.6% in 50-59 years of age,4.5 in over 60 years of age. To follow age growth, the proportion of fatty type was higher, 1.6 % in under 30 years of age, 5.80% in 30-39 years of age,5.5% in 40-49 years of age,10.8% in 50-59 years of age,38.6% in over 60 years of age. Before 60 years of age, to follow age growth, the proportion of fibroglandular type was higher, which achieved the peak value (79.2%) in 40-49 years and last to 50-59 years of age (80.6%) ,but it was decrease to 56.9% after 60 years of age. There was significant difference of the proportion in any age(P=0.000).The proportion of the benign lesion no difference in three categories. The proportion of malignancy lesion (6.23%, 16/257 mammary gland)in fatty type was higher than that in fibroglandular type (2.18%,37/1698 mammary gland) which was significant difference(P=0.000). There was no malignancy lesion in glandular type. Conclusions Significant correlation were present between uhrasonographic classification, age and malignancy lesion, no significant correlation were found between uhrasonographic classification, age and benign lesion.

Objective To investigate the effects of low molecular heparin(LWMH)on cytokines(TNF-?,IL-1? and IL-10)in blood plasma and bronchoalveolar lavage fluid of invasive pulmonary aspergillosis(IPA)mice.Methods The neutropenic IPA mouse models were established by administration of cyclophosphamide for immunologic function inhibition and intranasally challenge with Aspergillus fumigatus conidia(1?106 conidia/mouse).One hundred and twenty mice were randomly divided into 4 groups:normal control,IPA model,normal saline+LWMH and IPA+LWMH group.Normal saline+LWMH group and IPA+LWMH group received LWMH(subcutaneous injection,1 000 IU/kg,qd?2 d).Normal control and IPA model group received normal saline instedad of LWMH.At 4,8,12,24 and 48 h after inoculation,six mice were randomly taken from each group to be sacrificed.ELISA method was used to determine the concentrations of TNF-?,IL-1? and IL-10 in blood plasma and BALF.Results TNF-?,IL-1? and IL-10 in blood plasma and BALF increased significantly several hours after inoculation of conidia in IPA model and IPA+LWMH group.There were significant higher concentrations of TNF-? and IL-1? in blood plasma and BALF in IPA+LWMH group than in IPA model group(P

Objective To discuss the risk factors and nursing intervention of multidrug-resistant organism (MDRO) infection in patients of traditional Chinese medicine hospital (TCM). Methods By investigating the patients admitted to Beijing Xuan Wu Hospital of Traditional Chinese medicine from June 2015 to June 2016, 756 patients of them who were confirmed with clinical diagnosis of infection and pathogen detection with positive, which were divided into MDRO group including 97cases and non-MDRO group including 659 cases, then the pathogens of MRDO infection species and distributionwere counted, and analyzed risk factors for infection. Results A total of 756 cases were detected positive strains 816 strains, including 611 strains of monitoring target strains, 116 strains of MRDO. The top three were methicillin-resistant staphylococcus aurous 30.17%(35/116), Pseudomonas aeruginosa 18.97% (22/116) and Klebsiella pneumonia 18.10% (21/116). Single factor analysis results showed that the patients' age, hospitalization days, the history of other hospital admission, invasive procedure, basic chronic disease (diabetes, cerebrovascular disease, lung disease) and combined use of antibiotics were MDRO infection risk factors (χ2=9.470-198.609, P < 0.01); multivariate Logistic regression analysis showed that the independent risk factors of MDRO infection were the history of other hospital admission (OR=2.085, 95%CI1.040-4.179), invasive procedure (OR=3.063,95% CI1.526- 6.150), diabetes (OR=2.037,95% CI1.070- 3.877), cerebrovascular disease (OR=4.349,95%CI 2.035-9.293)and combined use of antibiotics (OR=18.723,95% CI9.202-38.094). Conclusions Patients of TCM have many characteristics, such as with more basic diseases, longer length of stay, elder and so on. So we should be alert to the risk of MDRO infection and take nursing interventions to prevent and strengthen the isolation prevention.

Objective To establish a human ovarian carcinoma cell line with directional highly lymphatic metastasis and to study their biological characteristics.Methods The clone cells of ovarian carcinoma,SKOV3,were inoculated into the hind foot pad of nude mice.The cancer cells of lymph node metastatic foci were transplanted into nude mice again when the metastatic nude of mice were observed.After repetition of this procedure for 3 cycles,the metastatic rate and the metastatic paths were observed in nude mice of every passage.We used limited dilution method to separate and select colonial cells with directional highly lymphatic metastatic potentials from the lymphatic metastasis of human ovarian carcinoma cell line SKOV3.The ceils with biological characteristics were assayed by growth curve,HE staining,karyotype analysis,nude mice transplantation and immunohistochemistry,respectively.Results We established a series of cell lines from lymph node metastasis and designated them as SKOV3-PM1,SKOV3-PM2 and SKOV3-PM3 cell strain.When the cells of SKOV3-PM3 were injected into the hind foot pad of nude mice, they produced 100%(10/10)spontaneous lymphatic metastasis.The lymphatic metastatic rates(26/10) were stable and higher than the mother cell line(1/10,P

Objective To investigate the effects and mechanisms of pin1(peptidyl-prolyl isomerase 1) inhibitor ju?glone on migration and invasion in glioma cell line U-87 MG. Methods Glioma cells were treated with juglone at 0, 0.8, 1.6 and 3.2μmol·L-1. Wound-healing assay and invasion assay were performed to examine the inhibitory activity of ju?glone on glioma cell line U-87 MG. Western blot was used to analyze the protein expression of β-catenin, VEGF, MMP-2 and MMP-9. Results The wound-healing assay showed that the wound-healing rate in juglone-treated groups was 46.04%±6.25%and 30.05%±13.35%at concentrations of 1.6μmol·L-1 and 3.2μmol·L-1 , repectively. Juglone treat?ment significantly reduced the wound-healing rate compared with controls (P<0.05). Transwell invasion assay showed that the number of invaded cells in juglone–treated groups was 103.67 ± 5.69 and 77.33 ± 7.77 at the concentrations of 1.6μmol·L-1 and 3.2μmol·L-1 , respectively. Juglone treatment significantly reduced cell invasion compared with con?trols (P<0.05). Treatment with juglone significantly down-regulated the expression levels ofβ-catenin, VEGF, MMP-2 and MMP-9 in U-87 MG cells in a dose-dependent manner. Conclusion The present data suggests that juglone has a significant inhibitory action on cell migration and invasion through down-regulation of theβ-catenin and its downstream VEGF, MMP-2 and MMP-9 protein expressions in glioma cell line U-87 MG.

Objective To investigate the inhibitory effects of RNA interference(RNAi)on the expression of matrix metalloproteinase-9(MMP-9)gene and invasiveness and adhesion of ovarian cancer cells.Methods Four groups of different specific target sequence in coding region of MMP-9 and one non- specific sequence were chosen,which were Sitel,Site2,Site3,Site4 and Site5.Small interference RNA (siRNA)expression cassettes(SEC)were constructed by PCR and transfected into ovarian cancer HO- 8910PM cells.RT-PCR and western blot were used to detect mRNA and protein expression of MMP-9 gene; the abilities of invasion and adhesion were detected by Matrigel invasion assay and cell adhesion assay. Results The expression of MMP-9 was inhibited and the inhibitory effects of different sequence were varied.The mRNA expression was 0.64?0.06,0.47?0.07,0.55?0.10 in Sitel,Site2,Site3 group, and protein expression was 0.30?0.09,0.27?0.08,0.37?0.12,respectively.Site2 group had the most efficient inhibitory effect,followed by Sitel and Site3 groups.Cell growth curve revealed that cell growth was significantly inhibited in Site2 group.Invasiveness and adhesion were significantly reduced,the inhibitory rate on invasion in Site1,Site2,Site3 groups were 50.0%,50.0% and 37.5%,respectively;the inhibitory rate on adhesion in Site1,Site2,Site3,Site4 groups were 43.8%,48.8%,33.9%,24.2% at 60 min and 41.6%,40.2%,35.1%,16.0% at 90 min,respectively.Conclusions RNAi exists in ovarian HO-8910PM cells.MMP-9 siRNA can specifically down-regulate MMP-9 expression and lead to the inhibition of invasiveness and adhesion in ovarian cancer cells.
