Chinese Journal of Practical Nursing 2009;25(14):19-22
Objective To assess the psychometric properties of the Chinese version of Family Man-agement Measure (FaMM). Methods FaMM was translated into Chinese and distributed to 330 caregivers whose children had chronic diseases to fill the questionnaire. Results Cronhach's alpha coefficient for the subscales ranged from 0.52 to 0.86, indicating acceptable internal consistency. The content validity index was 0.84. Construct validity was supported by significant correlation between FaMM and FAD and CBCL,Pearson correlation coefficient ranged from 0.11 to 0.38. The relationship among them accorded with the expected trends of Family Management Style Framework. The result of factor analysis indicated 9 factors explaining 60.08% variance. Conclusions The psychometric property of the Chinese version of FaMM was acceptable and it could be regarded as a reliable and valid instrument to measure the family response of Chinese families whose children had chronic diseases.

Objective To investigate the role of compound traditional Chinese medicine Yiqilin in the regulation of immune-related genes expression in spontaneously hypertensive rats(SHR).Methods Ten SHR were randomly divided into test group(fed with Yiqilin and ordinary food at the ratio of 1:9 for 6 months,n=5)and control group(fed with ordinary food for 6 months,n=5).Total RNA was extracted from myocardial tissues of SHR after 6 months,and gene chip hybridization technique was employed to analyse the expression of immune-regulated genes of myocardial tissues in two groups.The genes with differentiation expression were screened,and were verified by Real-time PCR.Results The expression of 32 immune-related genes were up-regulated in the test group,including interleukin(IL)6 receptor,IL-6 signal transduction factor,chemotatic factor,antigen presenting molecule,antibody receptor,heat shock protein(Hsp), etc.No immune-related gene was down-regulated in test group.The results of 2 immune-related genes(Hsp 105 and Hsp 90)detected by Real-time PCR were consistent with those by gene chip hybridization.Conclusion Part of the immune-related genes in myocardial tissues in SHR may be up-regulated by Yiqiling,which indicates that Yiqiling may play a role in the regulation of expression of immune-related genes in SHR.
5. Effect of Rosiglitazone on oxygen free radical and biochemical parameters in aged SD rats
Academic Journal of Second Military Medical University 2010;30(2):183-186
Objective: To observe the effect of Rosiglitazone (RGTZ) on oxygen free radical and biochemical parameters of aged rats, so as to establish a basis for anti-aging study. Methods: The 24-month-old naturally aged SD rats were randomly divided into the control group (CONT), the RGTZ group and the caloric restriction group(CR). The RGTZ group was given intragastric administration of RGTZ (4 mg · kg-1 · d-1) and the CR group was given 60% of the diet that of the CONT group. The rats were killed 12 weeks later and the serum malondialdehyde(MDA) content, superoxide dismutase(SOD) activity and the blood biochemistry parameters were examined. Results: The blood glucose (GLU), aspartate transaminase (AST), alamine transaminase(ALT), serum creatinine (SCr), and blood urea nitrogen (BUN) were within the normal range in all groups. Compared with the CONT group, blood cholesterol (CH) in RGTZ group was lower, but with no significant difference. The serum triglyceride(TG) of both RGTZ and CONT groups decreased markedly than those in the CONT group(P<0.05). The activities of SOD and MDA were improved in RGTZ and CR group compared with the control group. Conclusion: RGTZ can regulate the lipid metabolism and attenuate the oxidative damage in aged rats, indicating its anti-aging effect.
6. Expression of peroxisome proliferators-activate receptor γ in renal tissue of aging rats and its relationship with oxidative stress
Academic Journal of Second Military Medical University 2010;29(11):1293-1295
Objective: To investigate the expression of peroxisome proliferator-activate receptor γ(PPARγ) in the kidneys of rats at different ages, so as to study the possible association of PPARγ expression with oxidative stress in the aging process. Methods: Rat aging model was established using 3-, 12-, and 24-month old rats. Western blotting was used to determining the protein expression of PPARγ. The changes anti-oxidative ability of renal tissue were studied by determining the activities of superoxidedismutase(SOD) and glutatio-neperoxidase(GSH-PX). Results: Western blotting assay showed that the renal expression of PPARγ protein decreased with the aging of rats,with that of 3-month group significantly higher than that of the 24-month group(P<0.01). The activities of SOD and GSH-PX deceased with the aging of rats(P<0.01). Both the SOD activities were positively correlated with the expression of PPARγ protein(r=0.90, r=0.89, P<0.01) Conclusion: Renal PPARγ has a decreasing tendency during the aging process of rats, which is correlated with the down-regulation of anti-oxidative ability of renal tissue.

Objective:To prepare and optimize sorafenib-Eudragit RS nanoparticles( S-E üPs)and investigate the physicochemi-cal properties. Methods:S-E üPs were prepared by a solvent-nonsolvent method. Single factor experiments were used to research the effect of solvent,stabilizer type,carrier ratio and the proportions of water phase and organic phase on the physicochemical properties of S-E üPs. S-E üPs were evaluated by the particle size,zeta potential and morphology,and the in vitro drug release of S-E üPs was studied using dialysis technology. Results:The mean size was(86. 72 ± 3. 71)nm,the PDI and zeta potential was(0. 20 ± 0. 032)and (36. 6 ± 0. 3)mV,respectively,S-E üPs showed spherical shape with uniform distribution. The drug release in vitro was accorded with a Weibull equation. Conclusion:The solvent-nonsolvent method is appropriate for the preparation of S-E üPs. The nanoparticles have small particle size,uniform distribution,regular morphology and significant sustained-release property.
