Objective To investigate the current status and influencing factors of falls self-efficacy among the stroke elderly patients.Methods Totally 170 elderly stroke patients were investigated using the Modified Falls Efficacy Scale (MFES),and they were tested with Berg Balance Scale (BBS) and Time Up and Go Test (TUGT).Results The average score of falls self-efficacy was 108.There were 50.6% elderly stroke patients assigned to the group with low falls self-efficacy.Multiple Logistic regression analysis indicated that impairments of balance and mobility,severe stroke-related disability were the independent influencing factors associated with FOF,which could explain 52.0% of variations.Conclusions Low falls self-efficacy among the stroke elderly patients is a common complaint,nurses and physicians should focus on this problem,interventions combining exercise and education of accidental falls should be taken to improve falls self-efficacy of elderly stroke patients,and prevent falls finally.

Objective To study the expression of pericyte and the association between pericyte and angiogenesis in the endometriosis. Methods the endometriosis group is consisted of 20 ectopic endometrium, 20 eutopic endometrium dur-ing proliferation phase, 20 eutopic endometrium during secretory phase of patient with endometriosis. The control group (non-endometriosis ) include 20 normal endometrium during proliferation phase and 20 normal endometrium during prolifer-ation phase of women without entometriosis. The histological morphology parameters such as mean density of microvessel (MVD), pericytes number(PN)as well as the average ratio of pericyte to endothelial cells in microvessels were measured by immunohistochemical and morphological assesses. Results The expression of MVD was lower in the normal endometrium and eutopic endometrium compared with it in ectopic endometrium tissue. The difference of the MVD among the different groups was statistical significant (P<0.05). The expression of MVD in secretory phase endometrium was higher than it in proliferative phase endometrium (P<0.05), and it shows no significant difference between eutopic endometrium and normal endometrium. The expression of PN and PN/MVD in ectopic and eutopic endometrium in EMs group were lower than those in control group. However, we also found that the difference of PN and PN/MVD was not statistically significant. Conclusion Pericytes play an important role in angiogenesis of the endometriosis ,and pericyte coverage contribute to maturing of func-tional vasculature of endometriosis.

Objective:In the past study, a plasmid of pcDNA3 hCG? C3d3 had been constructed. It was suggested that the fusing protein be expressed by the pcDNA3 hCG? C3d3 plasmid both in the transient expression system in COS 7 cells, and the stable expression system in CHO cells. In the present research, it would be testified that the C3d molecular adjuvant could improve the immunogenicity of the hCG? DNA immunization or not. Methods:BALB/C mice of 6 weeks old were immunized intramuscularly two times at interval of 3 weeks by the plasmid pcDNA3, pcDNA3 hCG?, pcDNA3 hCG? C3d3 at dosage of 5, 10, 20 pmol, respectively. The anti hCG? antibody titers were determined by indirect ELISA in 6 weeks of last immunization. Results:The result showed that the C3d molecular adjuvant could increase significantly the titer of anti hCG? antibody in a dose dependent manner after DNA immunization.Conclusion:The C3d molecular adjuvant does improve the humoral immunity of the hCG? DNA immunization, which would be helpful for technical progress and clinical trial of the contraceptive vaccine. [

BACKGROUND: The central position of dendritic cells (DCs) has aroused increasing attention due to strong antigen presentation capability in anti-tumor. However, how to obtain enough functional DCs and reports regarding immunomodulator with low toxicity are few. OBJECTIVE: To investigate the effect of mycobacterium phlei F.U.36 (Utilins) on the proliferation and maturity of DCs derived from human umbilical cord blood in vitro.METHODS: The mononuclear cells were isolated from human umbilical cord blood using Ficoll-Hypaque method and cultured with Utilins, cytokine (human recombinant granulocyte/macrophage colonystimulating factor + recombinant human tumor necrosisfactor-α + recombinant human interleukin-4), or combination cytokine + Utilins, respectively. In addition, cells cultured with RPMI-1640 served as controls. Morphological features and growth of DCs were observed by an inverted microscope. Thephenotype changes of DCs, such CD1a and HLA-DR, were detected by flow cytometry at 9 days after culture. Moreover, DCs were stained by Wright-Giemsa and observed under oil lens. RESULTS AND CONCLUSION: Typical DCs with high expressions of CD1a and HLA-DR were obviously detected in all experimental groups except the control group. The positive rates of CD1a and HLA-DR in the Utilins group were higher than those in the control group, but lower than the cytokine group (P < 0.05). The HLA-DR positive rate of the combination group was higher than that of the cytokine group (P < 0.05). The results revealed that, Utilins can not only promote the proliferation of DCs derived from human umbilical cord blood in vitro but also cooperate with cytokines to induce the maturity of DCs.

Objective To study the feasibility of Brainlab plus 6-degree-of-freedom(6D) couch in the radiotherapy of head and neck by using their setup error.Methods Twenty-four patients with head and neck neoplasms in our hospital during AugustOctober 2016 were taken as the examples.After positioning by technician,each Brainlab was carried out,the setup errors in 3 translation directions of left-to-right(X),head-to-foot(Y) and abdomen to-back(Z) and 3 pivoting directions of Rx,Ry and Rz were obtained after registration of positioned CT image.After adjustment,Brainlab re-scanning was conducted for getting corrected errors.Results The online correction by Brainlab plus 6D obviously reduced the setup errors.The setup errors in all directions approached to 0,in which the difference between Ry and Rz directions had no statistical significance(P>0.05),while the difference among the X,Y,Z and RX directions was statistically significant(P<0.05).Conclusion The online corrections of Brainlab combined with 6D considerably reduces the errors in translation and rotation directions in radiotherapy of head and neck neoplasms,thus reduces normal tissue received amount and increases the radiotherapeutic accuracy.

Objective To improve hand hygiene compliance among healthcare workers (HCWs)in a stomatological hos-pital,and effectively reduce healthcare-associated infection(HAI)rate.Methods According to WHO hand hygiene guide-line and implementation scheme of hand hygiene,a systemic and step by step hand hygiene promotion plan was formulated, the plan was divided into five steps:full alert,baseline investigation,improvement,tracking,and retrospective analysis. Hand hygiene compliance among HCWs before and after the promotion of activities was analyzed and compared. Results Through hand hygiene promotion activities,the questionnaires showed that average score of knowledge about hand hygiene among HCWs enhanced from 58.33 to 77.40 (increased by 32.69%);the average hand hygiene compliance rate increased from 24.28%(59/243)to 49.81%(133/267),the difference was significant(χ2 =35.331,P =0.000);hand hy-giene status at five moments for hand hygiene improved markedly.Conclusion Hand hygiene promotion has a significant in-fluence in hand hygiene among HCWs in this stomatological hospital.
