ABSTRACT
Objective:To observe the effects of intervention based on self-regulation mode on illness perception, medical coping styles and quality of life of patients with psoriasis.Methods:Eighty patients with psoriasis from February 2018 to August 2019 in Qinhuangdao First Hospital were selected and divided into two groups by random digits table method, 40 patients in each group. The control group was given routine intervention, and the experimental group was given intervention based on self-regulation mode. The Illness Perception Questionnaire-Revised (IPQ-R) scores, Medical Coping Modes Questionnaire (MCMQ) scores, dermatologylifequalityindex (DLQI) scores and compliance of the two groups were compared before and after intervention.Results:There was no significant difference in the score of IPQ-R, MCMQ, DLQI before intervention between the two groups( P>0.05). After intervention, scores of symptoms, disease perception and causes of the disease in IPQ-R were (7.24±0.75), (162.34±20.35), (76.23±8.65) points in the experimental group and (6.08±0.72), (123.26±18.57), (52.79±7.84) points in the control group, there were significant differences between the two groups ( t values were 7.057, 8.972, 12.699, P<0.01). In the MCMQ, facing score,avoidance score and yielding score were (25.67±2.83), (12.26±1.84), (9.12±1.24) points in the experimental group, (21.76±3.89), (14.35±2.48), (10.45±1.68) points in the control group, there were significant differences between the two groups ( t values were 5.141, -4.280, -4.028, P<0.01). The DLQI scores of experimental group were significantly higher than those of control group ( t values were 2.648-8.244, P<0.05 or 0.01), and compliance of experimental group (97.5%, 39/40) was significantly better than control group (80.00%, 32/40) with statistically significant( Z value was 40.000, P<0.01). Conclusions:Intervention based on self-regulation mode can effectively reduce negative emotions of patients with psoriasis, increase their illness perception and compliance, improve their medical coping styles, self-management ability and quality of life, with positive application value.
ABSTRACT
Objective To explore the effects of homocysteine (Hcy) on neural stem cell (NSC) proliferation and the mRNA expression level of Notch1 and Hes1 related Notch signaling pathway from neonatal rats in vitro. Methods NSCs from neonatal rats were cultured by serum-free culture method in vitro. Cells were divided into four groups: control group (Hcy-C), low dose Hcy (Hcy-L) group, middle dose Hcy (Hcy-M) group and high dose Hcy (Hcy-H) group. NSCs were iden- tified by immunofluorescent staining using the antibodies against Nestin, β-tubulin Ⅲ and GFAP. The proliferation ability of NSCs was detected by MTT. The mRNA expressions of Notch1 and Hes1 were detected by Real-time PCR. Results In the serum free suspension medium, neurospheres that consisted of a great number of nestin-positive cells were found. β-tu- bulin Ⅲ positive neurons and GFAP positive astrocytes were detected by immunofluorescence staining on the 6 th day of cell induction. MTT assay showed that the cell viability was significantly lower in three Hcy treatment groups than those of con- trol group (P ＜ 0.05). And the effect of concentration-dependent was observed. The results of RT-PCR showed that mRNA expression of Hes1 was significantly lower in three Hcy treatment groups than that in control group (P ＜ 0.05). The mRNA ex- pression of Notch1 was significantly lower in Hcy-H group than that of other three groups (P ＜ 0.05). The mRNA expression of Notch1 was significantly lower in Hcy-M group than that of Hcy-L group and control group (P ＜ 0.05). Conclusion Hcy could inhibit the proliferation of NSCs by down-regulating mRNA expression levels of Notch1 and Hes1 genes related to Notch signal pathway.
