ABSTRACT
To further explore the current situation of disease communication between cancer patients and their families in clinical practice, and provide decision-making reference for the construction of harmonious doctor-patient relationship. From September to November, 2021, 10 oncologists from a third-class A general hospital in X city were selected for semi-structured interviews by objective sampling method, and Colaizzi seven-step analysis was used to analyze, refine and summarize the interview data. The results showed that the current situation of disease communication between cancer patients and their families can be summarized into three themes: concealing information during the diagnosis period, embarrassing decision-making during the treatment period, and difficult in autonomy at the end stage of the disease. Based on this situation, this paper suggested that a clinical communication mode with medical staff as a bridge and patients and their families actively facing and participating together can be constructed from different dimensions such as disease notification, win-win cooperation and psychological care.
ABSTRACT
OBJECTIVE： To study the mechanism of wound healing promotion of Panax notoginseng-Bletilla striata gum sponge on diabetic foot ulcer （DFU） model rats. METHODS： Healthy SD rats were selected and given high-lipid and high-glucose diet， intraperitoneal injection of streptozotocin once to establish diabetes model. Neodymium-iron-boron magnet was used to press the back of rats to make ulcer wound then established DFU model. Totally 60 DFU model rats were randomly divided into group A（blank group， i.e. normal saline gauze group）， group B（vaseline gauze group），group C （gelatin sponge group） and group D （P. notoginseng-B. striata gum sponge group）， with 15 rats in each group. The rats were given corresponding gauze/sponge to cover the wound for intervention treatment， changing dressing once every 1-2 days. On the 3rd and 7th day after intervention， the wound healing of rats in each group was observed with naked eyes， and the wound healing rate was calculated. The wound margin tissue was collected to obtain HE staining section， and histopathological observation was conducted under microscope. mRNA expression of β-catenin， GSK-3β and Rspo3 in wound tissue were determined by RT-PCR. RESULTS： On the 3rd and 7th day after intervention， compared with group A， B， C， healing rate of group D was increased significantly （P＜0.05）； inflammatory cell infiltration， collagen deposition， capillary and granulation tissue growth in wound tissue increased significantly. The mRNA expression levels of β-catenin and Rspo3 all increased， and those of GSK-3β all decreased； except for the difference of β-catenin at the 3rd day and GSK-3β at the 7th day after intervention between group D and group C were not significant， the difference of other indicators was statistically significant （P＜0.05）. CONCLUSIONS： P. notoginseng-B. striata gum sponge can effectively promote the wound healing in DFU model rats， the mechanism of which may be associated with up-regulating the expression of β-catenin and Rspo3 mRNA and down-regulating the expression of GSK-3β mRNA.
