Objective To investigate the effect of Roy Adaptation Model(RAM)in patients with adolescent insanity.Methods One hundred patients with adolescent insanity during October 2011 to March 2012 were randomized in equal number into two groups by random digit table:the study group and the control group.The former were intervened with RAM and the latter received routine care and health education.Seven weeks after intervention,Hamilton Depression Rating Scale(HAMD),Hamilton Anxiety Scale(HAMA) and Observation Scale(NOSIE)were used for the assessment. Results After intervention,the scores on HAMD and HAMA in the study group were significantly lower,compared to the control group(P<0.01).The scores on social function,social interest,subjective support and use of social support were all significantly higher than those of the control group(all P<0.01). Conclusions RAM can improve their ability of the patients with adolescent insanity to adapt to the environment.It may improve their mental state and their quality of life.

BACKGROUND:It is wel-known that vitamin E holds antioxidant capacity, but whether other growth factors have the same effect on endplate chondrocytes has not yet been reported. OBJECTIVE:To observe the effect of different growth factors on the antioxidant ability of endplate chondrocytes in the intervertebral disc. METHODS:Endplate chondrocytes were primary cultured, and then divided into four groups, including blank control, serum deprivation, hydrogen peroxide stimulation and hydrogen peroxide stimulation combined with different growth factors groups. The 4th group was subdivided into insulin-like growth factor-1, basic fibroblast growth factor, transforming growth factorβ, forskolin and vitamin E groups. The expression levels of caspase-3, matrix metal oproteinase 13 and 3, inhibitor of metal oproteinase 1 as wel as thrombin 4 and 5 were detected by real-time PCR. Cel apoptosis was analyzed through apoptosis kit and flow cytometry. Cel synthesis and secretion were detected by western blot assay. The total antioxidant capacity and the hydrogen peroxide content were determined by kit, and then statistical y analyzed. RESULTS AND CONCLUSION:Different growth factors had significant differences in the endplate chondrocyte apoptosis, secretion and antioxidant capacity. To conclude, transforming growth factorβand forskolin do further damage to the cel s stimulated by hydrogen peroxide, while insulin-like growth factor-1 and vitamin E expose protective effect on the injured cel s.
