The content of superoxide dismutase (SOD) and lipid peroxide (LPO) of blood serum in 120 ulcerative colitis (UC) patient were tested by means of xanthine oxidation method and colorimeter on the reactive product of thio-barbituric acid.The content of SOD in the UC Patients was lower than that in the normal control group (P＜0.001),and the content of LPO in the UC patients was obviously higher than that the control group (P＜0.001).The content of SOD in the UC patients which accompanied the types of simple retention of damp-heat in the interior or weakness of the spleen and the stomach or the stagnancy of qi and blood stasis or deficiency of yin and stagnancy of qi and blood stasis was distinctly lower tban the one in the normal control groups (P＜0.001).The content of LPO in them is distinctly higher than the content of LPO in normal control group (P＜0.001).Conclusion: These results suggested that the content of SOD of protecting cell factor in the body of ulcerative colitis patients who were mostly the type of retention of damp-heat in the interior decreased and the content of LPO of damaging cell factor increased.When the patients accompanied with the deficiency,the content of the SOD in them reduced remarkably and the content of LPO enhanceed remarkably,especially in those who are the type of weekness of the spleen and the stomach or insufficiency of the spleen and the stagnancy of qi and blood stasis.

Objective To understand the job stressors, coping style and general self-efficacy of emergency nurses and relationship of them. Methods A cross-sectional study involving 83 emergency nurses were conducted through the Chinese Nurses′ Job Stress Sources Scale, Trait Coping Style Questionnaire, General Self-efficacy Scale. Results Job stress among nurses in emergency department was caused by heavy workloads and time distribution (2.88±0.82), issue of patient care (2.78±0.59). The score of emergency nurses′coping propensity was 3.77, indicating more use of positive coping. Negative coping scored higher than the norm (26.99±4.76 vs.21.25±7.41), the difference was significant (t=10.290, P<0.01). The average score of general self-efficacy was 2.40 ± 0.48, lower than the norm (2.86±0.52), the difference was significant (t=-8.07, P<0.01). Active coping style scores were negatively correlated with job stress (r =-0.294, P < 0.05), negative coping style scores were positively correlated with job stress (r =0.239, P<0.05). General self-efficacy and positive coping scores were positively correlated (r=0.270, P<0.05). Conclusions The job stress among emergency nurses was at high level, self-efficacy was not high, but they still have a positive behavior patterns. Nurse managers should take advantage of the positive psychological characteristics of nurses and give reasonable support and guidance, in order to enhance the confidence of nurses and promote self-efficacy, optimize coping, improve the physical and mental health in emergency nurses.

Objective To verify the analytical performance of the portable Celercare M1 analyzer in the C-reactive protein(CRP) quantitative determination.Methods According to the standard program of the American Clinical and Laboratory Standards Insti-tute (CLSI),The portable Celercare M1 analyzer was performed the verification on the CRP detection in the aspects of the linearity range,precision,accuracy,interference test and method comparison.Results The CRP detection showed good linearity in the range of 0.5-200 mg/L and the regression equation was Y =0.979X +0.456.The within-run coefficients of variation(CV)of samples with low and high CRP levels were 5.9% and 2.0%,respectively.The between-day CV of samples with low and high CRP levels were 6.3% and 2.2%,respectively.The accuracy of the assay was admirable,and bias of CRP results at low and high levels were 2.3% and 0.7%,respectively.No significance interference was observed when serum bilirubin ≤340 μmol/L,triglyceride ≤10 mmol/L and hemoglobin ≤8 g/L in this method.The regression equation of Celercare M1 analyzer(Y )and the IMMAGE 800 (X) for detecting CRP was Y =0.944X +0.206,R 2 =0.996(P <0.05).The relative bias of CRP results in three medical decision levels (3,10,100 mg/L)was 1 .0%,4.0% and 5.0%,repectively,which was lower than 1/2 of total error allowance.Conclusion The linearity,precision,accuracy and interference of the Celercare M1 analyzer in CRP determination are admirable and can be accepted in clinical practice.

Objective To explore the asymmetry of metabolic products of the auditory cortex in normal human brain after being stimulated by the pure tone with the proton magnetic resonance spectroscopy(1 H-MRS). Methods Twelve healthy volunteers, including 7 males and 5 females, were performed MRS tests before and after the stimulation of the pure tone of 90 dB in intensity and 1000 Hz in frequency. The the metabolites peak of the N-acetylaspartate (NAA) ,creatine(Cr) ,choline( Cho) , glutamine/glutamate ( Glx) and GABA in auditory cortex were investigated, The content of metabolic products were conducted with half-quantitative analysis. The differences of the NAA/( Cho + Cr) ,Glx/Cr and GABA/ Cr ratios before and after pure tone stimulation in the bilateral auditory cortex were analyzed. The difference of distribution of the metabolic products between the left and right auditory cortex was also analyzed to explore the asymmetry of the auditory cortex. Results The NAA/( Cho + Cr) and GABA/Cr ratios increased,the Glx/Cr ratio decreased in the left auditory cortex after being stimulated by the pure tone. There were significant differences in the NAA/( Cho + Cr) , Glx/Cr and GABA/Cr ratios before and after pure tone stimulation (P<0.05) ;the GABA/Cr ratio decreased,the Glx/Cr and NAA/( Cho + Cr) ratios increased in the right auditory cortex after being stimulated by the pure tone, and statistical difference of the GABA/Cr ratio was found before and after pure tone stimulation (P<0. 05) ,however the difference of the Glx/Cr and NAA/(Cho + Cr) ratios before and after pure tone stimulation was not significant (P>0.05). There were statistically significant differences in the Glx/Cr ratio of the auditory cortex between two sides after being stimulated by the pure tone. Conclusion The metabolic lateralization exists in auditory cortex of normal human brain after being stimulated by the pure tone, which may be the bases of the functional asymmetry.

Background and purpose:There are few studies referring to population-based cancer survival of bladder cancer for more than forty years in China. This paper was to offer basis for assessing long-term survival trends of bladder cancer and the prognosis of this cancer through analysis of the survival rates based on cancer report documents from 1972 to 2011 in Qidong.Methods:The deadline of the last follow-up for survival status of the 1 619 registered cases was Apr. 2012. Cumulative observed survival rate (OS) and relative survival rate (RS) were calculated using Hakulinen’s method performed by the SURV3.01 Software which is developed by Finnish Cancer Registry.Results:The one-, three-, five-, ten-, fifteen-, twenty-, and thirty-year OS rates were 59.91%, 43.49%, 35.98%, 26.91%, 21.30%, 18.37% and 12.24%; and the one-, three-, five-, ten-, fifteen-, twenty-, and thirty-year RS rates were 64.07%, 53.02%, 50.06%, 52.42%, 59.59%, 76.39% and 115.75%, respectively. For males, these OS rates were 60.84%, 43.91%, 36.95%, 27.31%, 21.49%, 18.29% and 12.59%, and RS rates were 65.23%, 53.95%, 52.02%, 54.57%, 62.59%, 79.12% and 117.07%, respectively; For females, these OS rates were 56.61%, 42.03%, 32.44%, 25.65%, 20.78%, 18.80% and 0%, and RS rates, 59.99%, 49.91%, 43.37%, 45.86%, 51.21%, 69.02% and 0%, respectively. There were no statistical differences couldbe found between both sexes (P=0.256). Five-year RS rates of age groups 15-34, 35-44, 45-54, 55-64, 65-74, and more than 75 were 49.10%, 67.53%, 62.77%, 53.92%, 46.59% and 39.85%, and 10-year RS rates, 49.79%, 61.23%, 52.99%, 48.21%, 54.94% and 51.21%, respectively. Remarkable improvement could be seen for the five-, ten-, and fifteen-year RS rates in this setting since 1980’s.Conclusion:The survival outcome from Qidong registered cases with bladder cancer shows gradual progress during the past 2 decades. Early detection and improvement of therapies may be the factors affecting the prognosis of bladder cancer. Although the disparities in survival rates between Qidong and the developed countries are getting narrower, potential for survival improvement still exists.
