ABSTRACT
BACKGROUND:Chinese nourishing kidney herbs can prevent osteoporosis and improve bone metabolism, which has been proved in animal and cel experiments. But there are few reports on the compatibility of Chinese nourishing kidney herbs, and it is difficult to screen the optimal compatibility, as the interaction of active ingredients and drug substance basis are uncertain. OBJECTIVE: To determine the proliferation, differentiation and Smad4 mRNA expression of neonatal Sprague-Dawley rat osteoblasts cultured by Chinese nourishing kidney herbs with different compatibility so as to find out the optimal compatibility of Chinese nourishing kidney herbs. METHODS: Passage 5 osteoblasts were divided into five groups: group A, 1×10-5mol/L icarin; group B, 1×10-5mol/L icarin+1×10-5 mol/L naringin; group C, 1×10-5mol/L icarin+1×10-5 mol/L diosgenin; group D, 1×10-5mol/L icarin+ 1×10-5mol/L catalpol; group E, 10 μL normal saline (control group). There were six wels in each group. RESULTS AND CONCLUSION: Compared with the group E, the proliferative ability of osteoblasts and expression of Smad4 mRNA were increased in the groups B and C; until the 72nd hour, the proliferative ability of osteoblasts in the group B reached the peak. At 48 hours of culture, the activity of alkaline phosphatase in groups B and C was higher than that in group E; at 72 hours of culture, the activity of alkaline phosphatase in groups B and D was higher than that in group E. These findings indicate that the compatibility of Chinese nourishing kidney herbs can influence the activity of osteoblasts, and icarin+naringin has the strongest effect.
ABSTRACT
Objective To explore the relationship among psychological flexibility,anxiety and depression in postoperative thyroid carcinoma patients.Methods A total of 184 postoperative thyroid carcinoma patients selected randomly were measured with Acceptance and Action Questionnaire-Second Edition (AAQ-Ⅱ),Cognitive Fusion Questionnaire (CFQ),Self-Rating Anxiety Scale (SAS),Self-rating depression scale (SDS),and the Meaning in Life Questionnaire-the presence of meaning(MLQ-P).Variance analysis,pearson correlation analysis and stepwise multiple regression analysis were conducted in 157 questionnaires which were effective.Results The scores of AAQ-Ⅱ,CFQ,SAS,SDS,MLQ-P were(17.62±7.63),(27.37± 11.00),(32.38±6.99),(34.73±7.87),(28.55±5.09) respectively.The MLQ-P scores were negatively correlated with other scales(r=-0.278 ～-0.427,P＜0.01).The correlations among AAQ-Ⅱ,CFQ,SAS,SDS were positive(r=0.359～0.784,P＜0.01).The SAS scores and SDS scores in postoperative thyroid carcinoma patients were higher than that in norm group(z=72.28,P＜0.01;z=2.25,P＜0.05).When stepwise multiple regression analysis was conducted on SAS and SDS scores,AAQ-Ⅱ,MLQ-P,CFQ could explain 24.2％ variance in anxiety,and AAQ-Ⅱ,MLQ-P could explain 24.4％ variance in depression.Conclusion The level of anxiety and depression in postoperative thyroid carcinoma patients is much higher than that in norm.The higher the psychological flexibility,the lower the depression level.Psychological flexibility has significant explanatory power on anxiety and depression.
