Status and specific manifestations of persistent psychological distresses in patients with breast cancer post-operation / 中国实用护理杂志

Objective To investigate the prevalence and specific manifestations of enduring psychological distress in patients with breast cancer after operation. Methods Totally 263 patients of the newly diagnosed breast cancer treated with the operation from August 2014 to August 2015 were collected by convenience sampling. Distress Thermometer (DT) and Problem List recommended by national Comprehensive Cancer Network was used to assess the persistent psychological distresses in the 6th, 15th, 20th, 25th, 30th months after the disease diagnosis,while a self-designed questionnaire was for the demographic data. Results The results of the DT screening showed that 16％(42/263) patients had persistent psychological problems;the incidences of five stages of significant psychological distress (DT≥4) was 43％(113/263), 34％(89/263), 31％(81/263), 28％ (73/263) and 25％ (65/263), respectively. The main manifestations of persistent psychological distress were:fatigue 59 cases (22.4％) , sleep disorders 51 cases (19.4％), nervous 48 cases (18.2％), anxiety 24 cases (9.1％), fear of appearance 23 cases (8.7％) and the difference in persistent psychological distress scores between different demographic characteristics (age, educational level, marital status, economic situation, operation method, disease stage) were statistically significant (t=-2.295-2.966, P<0.05). Conclusion The incidences of persistent psychological distress in patients with breast cancer is higher and the manifestation is different,which should be paid attention to by medical workers.

Platelet-rich plasma affects the proliferation and collagen production of mesenchymal stem cells / 中国组织工程研究

BACKGROUND:Mesenchymal stem cel s are the seed cel s for tendon tissue engineering which can be obtained in large quantities, but how to induce in vitro is a key technology. OBJECTIVE:To explore the effect of platelet-rich plasma on the proliferation and col agen production of in vitro cultured mesenchymal stem cel s. METHODS:The rabbit mesenchymal stem cel s were separated ad cultured. The high-dose platelet-rich plasma group, middle-dose platelet-rich plasma group and low-dose platelet-rich plasma group were set to induce the mesenchymal stem cel s, and the blank control group was set as control. RESULTS AND CONCLUSION:The proliferation of mesenchymal stem cel s in the high-dose platelet-rich plasma group, middle-dose platelet-rich plasma group and low-dose platelet-rich plasma group was high, and in rapid growth with big increase amplitude, and there was no significant difference in the proliferation when compared with the blank control group (P<0.05). The effect was positively correlated with the culture time, and after cultured for a certain time, the effect was in dose-dependent manner, as higher dose platelet-rich plasma had more significant effect on the proliferation of the cel s. The results indicate that platelet-rich plasma can significantly promote the synthesis of col agen type Ⅰ and Ⅲ of mesenchymal stem cel s, the higher the dose, the more significant the effect on the col agen.
