Objective To investigate factors influencing the quality of life (QOL) of cancer patients with bone metastases. Methods Eighty-two cancer patients with hone metastasis were investigated.A questionnaire designed according to European Organization for Treatment of Cancer quality of life questionnaire ( EORTC QLQ-C30),Monroe Dunaway Anderson symptom inventory-Chinese edition (MADSI-C) and hospital anxiety and depression scale (HADS) standards was used to collect the information. Results The average total standardized QOL score of these cancer patients was 53.28±19.20.Among the function subscales,social function got the lowest average score (47.54),while among the symptom subscales fatigue got the highest average score (56.65).According to the MDASI-C,the most serious symptom burdens were fatigue,distress and pain; working and walking experienced the most interference.The symptom burdens correlated significantly with the QOL results.Twenty-four of the patients (29.3％) had been diagnosed with anxiety,and 17 (20.7％) were diagnosed with depression.Anxiety and depression continued to be significantly associated with overall QOL and its various dimensions. Conclusions The results　show that the burden of fatigue and pain,as well as of anxiety and depression are significantly associated with impaired QOL among cancer patients with bone metastasis.Work (housework) and walking were the most severely affected activities.Psychological rehabilitation should be focused on the comprehensive treatment of patients with bone　metastasis along with other appropriate rehabilitation strategies to enhance their overall functioning,relieve their　symptoms and improve their QOL.

Objective To explore the therapy effect of candesartan plus CSDP on elderly hypertensive patients with renal dysfunction.Methods Eighty elderly patients with essential hypertension and renal dysfunction were selected as our subjects.All subjects were randomly divided into candesartan group and candesartan + CSDP group,every group for 40 subjects.Patients in candesartan group were treated with 4 mg candesartan once per day for 6 months.Patients in candesartan + CSDP group were given CSDP 10 capsules three times / day beside 4 mg candesartan,once per day for 6 months.The levels of Cr,BUN,Ccr changes were measured.Results Two therapy strategies can decrease blood pressure and the decrease rate of blood pressure in candesartan + CSDP group was higher than that of candesartan group.The level of Cr,BUN in patients with candesartan + CSDP group after treatment performing were (104.6 ± 6.5) μmol/L,(6.21 ± 4.80) mmol/L,lower than that in before treatment (196.8 ± 2.6) μ mol/L,(9.84 ± 3.20) mmol/L.And the Ccr increased from (58.1 ± 4.9)ml/min to (117.2 ± 6.4)ml/min.The differences were significant (t =2.213,2.302,2.136,P ＜ 0.05).However the differences between before and after treatment with only candesartan treat weren't significant (P ＜ 0.05).Conclusion Candesartan + CSDP might show a synergistic effect compared with candesartan in term of curing elderly hypertensive patients with renal dysfunction.

Objective To evaluate the role of signal transducer and activator of transcription 3 (STAT3) signaling pathway in the reduction of myocardial ischemia-reperfusion (I/R) injury by diazoxide postconditioning in rats.Methods Sixty adult male Sprague-Dawley rats,aged 3 months,weighing 240-260 g,were randomly divided into 5 groups (n =12 each):sham operation group (S group),I/R group,vehicle group (V group),diazoxide postconditioning group (D group),and STAT3 signaling pathway inhibitor Stattic group (St group).Myocardial I/R was produced by 30 min occlusion of left anterior descending branch of coronary artery followed by 120 min reperfusion.In V and D groups,0.4％ dimethyl sulfoxide and 7 mg/kg diazoxide (in 1 ml of 0.4％ dimethyl sulfoxide) were injected through the femoral vein at the onset of reperfnsion,respetively.In St group,Stattic was injected through the femoral vein 10 min before reperfusion,and the other procedures were the same as those in D group.The infarct size (IS) and myocardial apoptosis were detected by TTC staining and TUNEL,respectively.Apoptotic index (AI) was calculated.STAT3 mRNA expression in myocardial tissues was detected using RT-PCR.Western blot was used to detect the phosphorylation of STAT3.Results Compared with S group,the IS and AI were significantly increased and the expression of STAT3 mRNA and phosphorylation of STAT3 were decreased in I/R group (P ＜ 0.05).Compared with I/R group,the IS and AI were significantly decreased and the expression of STAT3 mRNA and phosphorylation of STAT3 were increased in D group (P ＜ 0.05).There was no significant difference in IS,AI,expression of STAT3 mRNA and phosphorylation of STAT3 between V group and St group (P ＞0.05).Compared with group D,the IS and AI were significantly increased and the expression of STAT3 mRNA and phosphorylation of STAT3 were decreased in St group (P ＜ 0.05).Conclusion STAT3 signaling pathway is involved in the reduction of myocardial I/R injury by diazoxide postconditioning in rats.
