Objective To investigate the effectiveness of the SF-36 health survey questionnaire used to investigate the quality of life (QOL) of the patients undergoing tibial bone transport.Methods Reliability analysis,correlation analysis and validity analysis were performed to evaluate the reliability and validity of the SF-36 scale.According to treatment time,94 patients who underwent tibial bone transport were divided into 3 groups:group A were 30 patients who had just started bone transport,group B 43 patients who had completed bone transport and removal of external fixation within 2 years,and group C 21 patients who had completed bone transport and removal of external fixation beyond 2 years.A mean comparison of items in the SF-36 scale was further carried out.Results The questionnaires were completed well.The Chonbach α indexes of all the items were more than 0.8,showing good reliability of the scale.Most of the correlation coefficients were almost or more than 0.5,indicating acceptable content validity of the scale.The QOL of the patients undergoing tibial bone transport was differentiated from that of normal people,proving good discriminant validity of the scale.Groups B and C obtained significantly better scores in all items of the scale than group A (P ＜ O.05).Group C scored significantly higher in physical functioning (PF) and role-emotional (RE) than group B (P ＜ 0.05),but there were no significant differences between the 2 groups regarding other items of the scale (P ＞ 0.05).Conclusions With good reliability and validity,the SF-36 health survey questionnaire can be used to assess the QOL of the patients undergoing tibial bone transport.The treatment of bone transport in the tibia can significantly and durably help improve the QOL of the patients.

Pain and anxiety engender major psychic problems during all phases of treatment for burn patients. Analgesic alone does not allay these problems satisfactorily in these patients. Music therapy, as an important complementary and alternative therapy, has been widely used in multiple medical fields. However, its positive effect on alleviation of pain and anxiety in burn patients is undefined. The objective of this review is to summarize the feasibility, application fields, methods, and the effectiveness of music therapy in allaying pain and anxiety of burn patients during the whole course of treatment.

Objective To investigate the effect of grape procyanidins (GPC) and the regulation of estrogen receptor(ER)on proliferation of human breast cancer(MCF-7)cells. Method MCF-7 cells were cultured with GPC,and divided into six groups: tumor control,high,middle and low dose GPC treated,estrogen antagonist ICI 182. 780 (ICI) control,ICI and GPC combined treated. The proliferation activity level of MCF-7 cells was determined by MTT assay,and the levels of the proliferating cell nuclear antigen (PCNA) and Bax protein were measured by immunohistochemistry method. Results Compared with tumor control group,the level of proliferation activity and the expression of PCNA were significantly decreased in high dose GPC group,while the expression of Bax protein was increased significantly. Compared with high dose GPC group,both the proliferation activity and the PCNA expression were increased,and Bax protein expression decreased significantly in ICI and GPC combined treated group. Conclusion GPC can inhibit the proliferation and induce the apoptosis of human breast cancer cells effectively,and its mechanism is closely related to the regulation of ER.
