Objective To establish the animal model of photochemical damage and investigate the protective effects and mechanism of taurine on the retina photochemical damage in rats. Methods Fifty rats were randomly divided into normal control group, light damage group and 4% taurine supplementation group. After 15 day cyclic light and 24-hour dark adaptation, the last two groups were exposed to (3000?200) lx transmitted by six cold white lights. After 24-hour exposure, the rats were stayed in darkness. The retinal morphology was detected through light and electron microscope and the retinal function was detected by Scot-ERG. The concentration of MDA and the activity level of SOD/GSH-px were measured. Results In light damage group, the a and b amplitude (Aa/Ab) were significantly decreased, but in taurine group, except the decreased Aa, others were of no significant changes. The retina inner and outer segments were swollen and in disorder after exposure, the outer nuclear layer got thinner than that of control. The mitochondria in light damage group was swollen, but in taurine group changes were less significant. After exposure, the concentration of MDA in retina was markedly increased in light damage group and the activity level of SOD/GSH-px were decreased, but in taurine group MDA slightly increased and SOD/GSH-px was up-regulated but of no significance. Conclusion Dietary supplementation with 4% taurine partially protected photoreceptor from degeneration, which might correlate with the antioxidation and inhibition of free radical character of taurine.

Objective: To observe the effects of taurine (Tau) on photoreceptor apoptosis and investigate the mechanism. Method: Seventy rats were randomly divided into control group (Cont) and 4% taurine supplementation group (Tau). The subjects were exposed to the cool white light (3000?200 lx)for 0, 1, 3, 6, 9, 12 or 24 h . The apoptotic index (AI) of photoreceptor was evaluated by TUNEL method. Meanwhile, levels of p65 in nuclear and caspase-1 were determined by Western-blot analysis and I?Ba mRNA was detected by RT-PCR . Results: After 9 h exposure, scattered TUNEL positive photoreceptors were found in Tau group, and each AI was lower than the corresponding control (P

OBJECTIVE To analyze resistance and detect plasmid-mediated AmpC genes in Klebsiella pneumoniae.METHODS The susceptibility of the K.pneumoniae to 13 antibiotics was tested by K-B method.Modified three-dimensional extract test was adopted to detect AmpC lactamases in K.pneumoniae.The genotypes of AmpC lactamases were determined by polymerase chain reaction and sequencing.RESULTS Among the 105 isolates,the rate of extended spectrum ?-lactamases(ESBLs) was 41.90%,the rate of AmpC ?-lactamases was 0.95% strains,and the rate of ESBLs and AmpC ?-lactamases was 2.86%.DNA sequence analysis conformed that AmpC lactamases positive isolates were DHA AmpC gene.The resistance rate to penicillins,cephalosporins,?-lactam/?-lactam inhibitors,monobactams,and fluoroquinolones was very high.The susceptibility rate to imipenem was 100.00%.CONCLUSIONS The plasmid-mediated AmpC gene is present in clinically isolated K.pneumoniae.The resistance can be transferred to homologous or different genera of bacteria.

Objective To investigate the status quo and influencing factors of compassion fatigue among nurses in psychiatric hospitals. Methods The self-designed demographic questionnaire,compassion fatigue scale,occupation-al identity assessment scale and social support rating scale were employed to investigate 480 nurses in five psychi-atric hospitals from two provinces. Results The scores for each dimension in compassion fatigue scale were as fol-lows:compassion satisfaction(32.26±5.34),occupational burnout(27.67±4.34),and secondary traumatic stress(23.72± 4.41).Age,position,individual monthly income,health status,job satisfaction and occupational identity had significant influence on compassion satisfaction(F=19.351,P<0.001). Individual monthly income,health status,job satisfaction and occupational identity had significant influence on occupation burnout (F=35.705,P<0.001). Individual monthly income, personality and social support had significant influence on secondary traumatic stress(F=17.203,P<0.001). Conclusion Nurses in psychiatric hospitals had severe compassion fatigue and this status was influenced by multiple reasons. Nursing managers should pay great attention to nurses with low monthly income,poor health,low job satisfaction, weak social support and low occupational identity,and take effective measures to decrease compassion fatigue of nurses.
