0.05). The daily average intake of protein, fat and carbohydrate was similar to the RNI. The energy percentage of three meals was 4∶4∶2. Conclusions The incidence rate of hyperlipemia is high. It is a dangerous module which affects the health of the old. Thus, the diet for the old should be improved for their health.

OBJECTIVETo verify the existence and significance of calcium/calmodulin dependent serine protein kinase/inhibitors of differentiation 1 (CASK/Id1) pathway in fibroblasts of human keloid.

METHODSImmunofluorescence laser was used to confirm CASK and Id1 protein expression and localization in fibroblasts of the keloid and normal skin. RT-PCR and Western-blot were adopted to analysis the CASK and Id1 expression and differences between keloid and normal skin fibroblasts. The natural combination of CASK and Id1 protein of keloid fibroblasts was tested by immunoprecipitation.

RESULTSCASK and Id1 protein expression were both found in fibroblast cells of keloid and normal skin under normal circumstances. Most of CASK and Id1 were distributed in the cytoplasm and nucleus of fibroblasts. The results of RT-PCR showed that the expression of CASK mRNA in the keloid group was 0.658 +/- 0.024, which was lower than that in the normal control group (1.076 +/- 0.008, t = 11.159, P < 0.05). The expression of Id1 mRNA was 0.497 +/- 0.014, which was higher than that in the normal control group (0.307 +/- 0.017, t = 15.148, P < 0.05). The results of Western-blot showed that the expression level for CASK protein in the keloid group was 0.057 +/- 0.006, which was lower than that in the normal control group (0.168 +/- 0.012, t = 13.524, P < 0.05); the expression of Id1 protein was 0.812 +/- 0.035, which was higher than that in the normal control group (0.368 +/- 0.031, t = 16.356, P < 0.05). The results of immunoprecipitation showed that Id1 could be detected in the CASK precipitate, while CASK also could be detected in the Id1 precipitate. There was a natural binding of CASK and Id1 in keloid fibroblasts.

CONCLUSIONCASK/Id1 signal pathway may be existed and involved in the proliferation of keloid fibroblasts, which is related with the occurrence of keloid.

Objective To assess the effect of iDose4 in image quality and radiation dosage in CT angiography of craniocervical arteries.Methods Imaging data of 50 patients with 256-slice spiral CT angiography of craniocervical arteries were randomly divided into two groups:(A) 120 kV,250 mAs (25 patients),(B) iDose4 100 kV,180 mAs (25 patients).Dose length product (DLP) of the two groups were compared.Objective image noise was compared by two blinded readers,t test and nonparametric tests were used for statistical analysis.Results The overall image quality score of group A (3 points =1 patient,4 points =6 patients and 5 points =18 patients) and group B (4 points =5 patients and 5 points =20 patients) were shown.The image noise of group A (1 point =1 patient,2 points =5 patients and3 points =19 patients) and group B (2 points =4 patients,3 points =21 patients) were also evaluated.There was no statistical difference in revealing rate of image quality scores and objective noise between the two groups (Z =-0.334,-0.218,P ＞ 0.05).The estimated effective radiation dose was reduced by 56％ in group B than in group A.DLP was significantly lower in group B [(642.4 ±36.6) mGy · cm]than in group A [(1462.1 ± 64.3) mGy · cm].Conclusion Low dose contrast medium of CT angiography can display craniocervical arteries and the intracranial arteries very well with high image quality.

Objective To investigate the effect of high-flux hemodialysis on insulin resistance and microinflammatory state in elderly diabetic nephropathy (DN) patients with maintenance hemodialysis(MHD).Methods A total of 49 elderly DN patients with MHD and 10 healthy controls undergoing health examination survey were enrolled.Levels of homeostasis model assessment of insulin resistance index(HOMA-IR),interleukin-6(IL-6) and high sensitivity C-reactive protein(hs-CRP) were analyzed and compared between patients and the controls.Patients with MHD were randomly divided into two groups:high-flux hemodialysis(HFHD) group and low-flux hemodialysis (LFHD) group.Changes of the parameters including HOMA-IR,IL-6,hs CRP and urea excretion rate(kt/v) were observed before and after treatment for 12 months.Results Levels of IL-6,hs-CRP and HOMA-IR were significantly higher in DN patients with MHD than in the control group [(126.22±13.23)ng/L vs.(12.68±3.63)ng/L,(12.13±1.73)mg/L vs.(2.55±1.27) mg/L,(4.83 ±1.23) vs.(0.32 ± 0.15),respectively,all P＜ 0.01].The levels of IL-6 and Hs-CRP were positively correlated with HOMA-IR in elderly DN patients (R =0.656,0.729,R2 =0.43,0.532,both P＜0.01).Compared with before treatment,levels of fasting insulin(Fins),HOMA-IR and IL-6 were decreased in HFHD group after MHD for 12 months (all P＜ 0.05),while there were no differences in levels of Fins,HOMA-IR,IL-6 and hs-CRP in the LFHD group before and after MHD (all P＞0.05).The levels of Fins,HOMA-IR and IL-6 were significantly lower in the HFHD group than in the LFHD group after MHD for 12 months(all P＜0.05).Conclusions Insulin resistance and microinflammatory are common observed in elderly DN patients with MHD.High-flux hemodialysis may decrease the levels of IL-6 and hs-CRP,and ameliorate insulin resistance and microinflammatory state.

This study aimed to investigate the effects of Shiquan Dabu Tang (SDT) on growth and angiogenesis of subcutaneously implanted tumors, hepatic metastases, and incision-implanted tumors after surgical removal of primary colon tumor in mice.

Objective Analyzing the impact of teachers' background characteristics on the Students' evaluation to improve the quality of teaching from the angle of the teachers professional development. Methods Based on the data of students' evaluation of teaching of Shanghai medical college of Fudan University from 2008 to 2011, the article analyzed the teachers' gender, age, job title, diploma, and other relevant background characteristics. Excell2007 was used to build dataset and the data was analyzed statistically by software of SPSS 11.0 and expressed with x±s. The statis-tical method of one-way analysis of variance was used to compare the teachers with different genders, education backgrounds, ages and professional titles, showing statistically significant difference (P<0.05). Results comparative analysis showed that no statistically significant differences existed in fac-ulty teaching evaluation scores among the teachers of different genders or different education back-grounds(P=0.613 9、0.891 0). There were however significant differences in teaching evaluation of teachers of diverse ages and professional ranks(P=0.017 3 and P=0.032 5). Conclusions According to the analysis results of faculty teaching evaluations, associate professors' teaching evaluation scores were lower than intermediate grade teachers', and the score of the teachers between the age of 41 to 45 was lower than that of the teachers between the age of 36 to 40. Therefore individual variations and various social backgrounds of teaching faculties should be taken into consideration and the corre-sponding countermeasures for the professional development of teachers should been put forward. In addition, the cultivation of new teachers, young and middle-aged teachers should be strengthened, and the proportion of teaching evaluation in the Performance Appraisal should be increased.
