RESUMO
Objective:To prepare a discharge readiness scale suitable for patients with enterostomy and to test the reliability and validity, so as to provide an effective measurement tool for the assessment of discharge readiness of patients.Methods:On the basis of the existing Chinese version of the discharge readiness scale, items related to enterostomy nursing problems were added to form the scale entry pool, and a draft of the scale was formed by expert consultation. 132 patients with preventive enterostomy admitted to the Affiliated Hospital of Qingdao University were pre-investigated with the original scale to test the reliability and validity.Results:The discharge readiness scale of enterostomy patients contained 18 items. The content validity of the scale was 0.969, and the content validity of each item was 0.824 - 1.000. Four common factors were extracted from the scale, and the cumulative variance contribution rate was 79.503%. Cronbach alpha coefficient of the total scale was 0.923, and each dimension was 0.806 - 0.947.Conclusions:The discharge readiness scale of patients with enterostomy has good reliability and validity, which can be used as an evaluation tool for patients at discharge.
RESUMO
Objective To explore the effect of social support and coping style on posttraumatic growth of ostomy patients. Methods A total of 237 patients with ostomy from Affiliated Hospital of Qingdao University were investigated using General questionnaire, Perceived Social Support Scale, Medical Coping Modes Questionnaire and Posttraumatic Growth Inventory by cross-sectional survey method from September 2017 to March 2018. The path of social support and coping style on post-traumatic growth was established by correlation analysis and structural equation model. Results The total score of posttraumatic growth in patients with ostomy was (66.76±12.20) points, which was at the upper-middle level. Correlation analysis showed that posttraumatic growth was positively correlated with comprehension of social support (r=0.551, P<0.01), positively correlated with face style (r=0.580, P<0.01), negatively correlated with avoidance style and resignation style (r=-0.334, P<0.01;r=-0.449, P<0.01). Structural equation model showed social support had directly positive effect on posttraumatic growth, path coefficient were 0.44. Face style, avoidance style, and resignation style had a partial mediating effect between social support and posttraumatic growth, and mediation effects account for 20.01％, 5.21％, 9.25％of the total effect, respectively. Conclusions The posttraumatic growth level of patients with ostomy needs to be improved. Medical staff should strengthen social support for patients and guide patients to adopt the positive coping styles, reduce the avoidance and resignation coping styles, and promote patients to get more posttraumatic growth, furthermore, improve their social adaptability and quality of life.
RESUMO
Objective To investigate the effects of inhibiting miR-29 on growth,invasion and metastasis of pancreatic cancer PANC1 cells,and explore the potential mechanism.Methods Oligonucleotides inhibiting miR-29 (anti miR-29) and control oligonucleotides (miR NC) were used to transfect PANC1 cells to establish anti miR-29 PANC1 cells and miR NC PANC1 cells.Transient transfection of PUMA siRNA,E-cadherin siRNA or NC siRNA was used to construct cotransfected anti miR29 + PUMA-siRNA-PANC1 cells and anti-miR-29 + E-cadherin-siRNA-PANC1 cells.Number of colony formations was observed,cell survival was detected by MTT,cell apoptosis was measured by flow cytometry,cell invasion was detected by transwell chamber assay,and cell migration was detected by wound healing assay.Subcutaneous injection of anti miR-29 PANC1 cells was used to establish xenograft nude mice model,and venous injection of anti miR-29 PANC1 cells was used to establish lung metastasis nude mice model,and the subcutaneous and venous injection of PANC1 cells served as control.The growth of xenograft and the number of lung metastatic nodules were observed.TUNEL method was used to detect cell apoptosis in xenograft and immunohistochemical analysis was used to detect PUMA and E-cadherin in xenograft.Results The survival rate of PANC1,miR-NC-PANC1 and anti-miR-29-PANC1 cells was 100％,(96.8 ± 2.8) ％ and (24.4 ± 3.2) ％.The number of colony formation was (213 ± 36),(196 ± 28) and (37 ± 6) per 100 high power field.The number of transmembrane cells was (56.3 ± 9.6),(49.8-± 7.3) and (11.2 ± 3.4) per 400 high power field.The distance of cell migration was (260 ± 48),(247 ± 46) and (53 ± 7) μm.Cell apoptosis rate was (1.5 +0.9) ％,(2.6 + 0.9) ％ and (22.4 + 2.8) ％.There was statistically significant difference between anti miR 29 PANC1 cells and other PANC1 cells (P ＜0.05).The survival rate,apoptosis rate,transmembrane cells and migration distance of anti-miR-29 + PUMA-siRNA-PANC1 cells was (84.7 ± 10.9) ％,(1.3 ± 0.8) ％,(49.7 ± 6.4) per 400 high power field and (182 ± 36) μm,indicating that the effects of miR 29 inhibition on PANC1 cells were abolished (all P ＜0.05).The volume of the xenograft of PANC1 and anti-miR-29-PANC1 cells was (3 800 ±270) and (1 890 ± 160)mm3,the cell apoptosis rate was 0.93 ±0.14 and 8.26 ± 1.15,the number of metastatic lung lesions was (26.4 ± 6.5) and (8.6 ± 2.7),the PUMA positivity was (7.2 ±1.6) ％ and (43.8 ± 7.6) ％,E-cadherin positivity was (8.3 ± 3.6) ％ and (47.4 ± 5.7) ％,respectively.The xenograft volume and the number of metastatic lung nodules of anti miR29 PANC1 cells was obviously decreased or decreased,but cell apoptosis rate,PUMA positivity and E cadherin positivity were obviously increased,and the differences were all statistically significant (P ＜ 0.05).Conclusions Inhibiting miR-29 expression can decrease cell proliferation,migration and metastasis of PANC1 cells,and the potential mechanism may be associated with the upregulation of PUMA and E-cadherin.
RESUMO
Objective: To investigate the influence of fast tract surgery on the humoral immunity and the chief clinical index of gastric cancer patients.Methods: 56 patients with gastric cancer from December 2007 to June 2008 were randomly divided into two groups: experiment group(fast tract surgery group, n=28)and control group(conventional treatment group, n=28 ). The changes of serum levels of humoral immunity and the chief clinical index were analysed and compared.Results: The serum levels of humoral immunity in both group were decreased. The serum levels of C3 and C4 on the postoperative 1st day were(0.845±0.126)g/L and(0.212±0.070)g/L respectively(P<0.05) in FTS group.The serum levels of IgA, IgM and IgG on the postoperative 3rd day were(1.603±0.468)g/L,(0.845±0.187)g/L,(9.548±1.920)g/L respectively(P<0.05) in FTS group. The duration of antibiotic use, first passage of flatus, the lengh of hospital stay, the occurance of postoperative complications in FTS group were also significiantly lower than those in control group (P<0.01, P<0.05).Conclusion: Fast tract surgery affectes on the humoral immunity of gasrtic cancer patients, and it might contribute to the improved outcomes of postoperative patients.
