Objectives To validate the Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP) in hospitalized pediatric patients, and to assess the nutritional status and nutritional risk using STAMP. Methods the nutritional status of hospitalized pediatric patients was investigated by adopting STAMP. The STAMP score≥4 was deifned as a high standard of nutritional risk. Results Among 1 506 hospitalized children, children with high nutritional risk accounted for 26.56%. The overall prevalence of malnutrition and stunting was 19.12%and 10.16%, respectively. There was signiifcant diffe-rence in stunting among each department (P<0.05), which was the highest in department of internal pediatrics. The proportion of patients receiving nutritional support was 10.09%. Among them, the rate of parenteral and enteral nutrition support was 7.84%and 2.92%, respectively. The ratio of parenteral nutrition to enteral nutrition was 2.68:1. After intervention to hospitalized pa-tients with high nutritional risk, the overall prevalence of high nutritional risk decreased from 26.56%at admission to 21.71%at discharge (P<0.05). Conclusions STAMP can objectively relfect the possible malnutritional risk in hospitalized pediatric patients. The nutrition condition of the pediatric patients can be improved through nutritional risk management.

Objective To understand the personality and self-rated health status and the relationship between them in medical students. Methods By multi-stage cluster random sampling, 878 medical students were selected to investigate the personality by Eysenck Personality Questionnaire-Revised (Short Scale For Chinese) and the health status by self-rated health measurement scale (SRHMS1.0). Results The score of L dimension among male and female medical students was significantly higher than that of nation- wide young population. The scores of E, N and P dimensions had no significant difference between them. The score of P dimension of male students was significantly higher than that of female students. The score of students' SRHMS was 339.28?41.19, which was higher than that of general population in China. The score of physical health subscale among male and female students was 144.90?11.41 and 142.73?11.36, respectively (t=2.829, P=0.005). The scores of SRHMS and its three subscales were significantly different in medical students with different personality traits except the score of physical health subscale in students with different grades of P dimension. The scores of E and L dimensions had significantly positive correlation with SRHMS, and the scores of N and P dimensions had significantly negative correlation with SRHMS. Conclusion The personality traits of medical students were remarkably influenced on their self-rated health. To encourage medical students to reform the wholesome personality will be helpful to their health.

Mutations and deletions of the tumour suppressor PTEN are frequently involved in the development of cancer.However, PTEN is also tightly controlled by various non-genomic mechanisms,such as the epigenetic silen-cing of PTEN, post-transcriptional regulation by non-coding RNAs and post-translational modification.

Objective To investigate the effect of ketamine on the cGMP content in cerebral cortex, hypothalamus and brain stem in a rat model of CFA-induced arthritis. Methods Twenty-four SD rats weighing 200-220 g were randomly divided into three groups with 8 animals in each group, group Ⅰ: normal rat + intraperitoneal normal saline (ip NS);group Ⅱ : arthritic rat+ ip NS;group Ⅲ: arthritic rat + ip ketamine 100mg?kg-1 . Arthritis was produced by injecting CFA 0.05 ml into left ankle joint which developed inflammatory response within 24h and became hyperalgesic. The hyperalgesia persisted for more than 6 weeks. Three days after the arthritis model was established, paw withdrawal latency (PWL) to radiant heat was measured. 15 min after ip ketamine the animals were decapitated and cerebral cortex, hypothalamus and brain stem were separately isolated for determination of cGMP content using radioimmunoassay. Results In arthritic rats the PWL was significantly shortert (6.7 ? 1.2)s] than that in the normai rats [(12.5?1.9)s] ( P

Objective: To observe the clinical efficacy of electroacupuncture (EA) plus long-snake moxibustion for rheumatoid arthritis (RA) due to kidney deficiency and cold coagulation. Methods: A total of 60 patients in active stage of RA were randomly divided into an observation group and a control group, with 30 cases in each group. Patients in the control group took methotrexate tablets and nimesulide dispersible tablets orally for treatment, while those in the observation group received additional treatment of EA plus long-snake moxibustion. Both groups were treated for 12 weeks. The post-treatment changes in symptomatic grading and quantifying score, disease activity score with 28 joint counts (DAS28), and inflammatory indicators erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were observed, and the efficacy was evaluated. Results: The total effective rate in the observation group was 89.9％, versus 76.6％ in the control group, and there was a significant difference in the total effective rate between the two groups (P<0.05). After treatment, the symptomatic grading and quantifying score and DAS28 in both groups were significantly improved (all P<0.05), and the improvements in the observation group were more significant than those in the control group (both P<0.05). Besides, there were 11 cases with low disease activity index (DAI) and in remission in the observation group versus 5 cases in the control group, showing a statistically significant between-group difference (P<0.05). The ESR and CRP scores in both groups were significantly reduced after treatment (all P<0.05), also showing statistically significant between-group differences (both P<0.05). Conclusion: The efficacy of additional EA plus long-snake moxibustion based on oral medications for RA due to kidney deficiency and cold coagulation is better than that of the oral medications alone.

ObjectiveTo observe the effect of bionics pulsed electromagnetic fields (BEMF) on the biomechanical property of ovariectomized Wistar rats.MethodsForty 6 month old female Wistar rats were randomly divided into four different groups: ovariectomy group (group A), sham operation group (group B), BEMF+ovariectomized group (group C) and estrogen+ovariectomized group (group D). All rats were subjected to bilateral ovariectomy except group B. 8 weeks after operation, rats of group D were given estrogen 0.5 mg/kg/2 w. Rats of group C were exposed to BEMF, 1 h /d. Rats of group A and B were given nothing as control groups. All treatments was being kept for 10 weeks. After treatments finished, measuring the biomechanical property of femur and lumbar spine.ResultsThere were significant differences in the biomechanical property between group D and group A, and group C and group A (P<0.05).ConclusionBEMF can improve the biomechanical property of ovariectomized Wistar rats significantly and increase the capability of resisting fracture significantly.
