Chinese Journal of Practical Nursing 2017;33(8):612-615
Objective To investigate the effects of professional benefit recognition to stress coping of tuberculosis nurses. Methods A total of 82 tuberculosis nurses were assigned into experimental and control groups by random digits table method with 41 cases each. The experimental group was given four times of professional benefit recognition interventions in additional to regular training, while control group was just given regular training. The two groups were asked to complete the Professional Benefit Recognition questionnaires and Stress Coping Style questionnaires before the intervention and 1 month after the intervention, respectively. Results Before the intervention, the scores of the Professional Benefit Recognition questionnaires and Stress Coping Style questionnaires between two groups had no significant difference (P>0.05). After the intervention, the Professional Benefit Recognition questionnaires scores of experimental group increased from ( 2.93 ± 0.40) points to (3.81±0.38) points that was significantly better than that of control group(2.99±0.39) points, and there were significant differences (t=49.337,-60.834, P<0.05). The immature and mixed Stress Coping Style questionnaires scores of experimental group: self- accusation, illusion, avoidance, rationalization were (0.51 ± 0.13) , (0.51 ± 0.24), (0.56 ± 0.21), (0.51 ± 0.16) points, which were significantly lower than before the intervention (0.70 ± 0.09), (0.65 ± 0.10), (0.67 ± 0.14), (0.67 ± 0.08) points and that of control group (0.63 ± 0.16), (0.65 ± 0.18), (0.68 ± 0.18), (0.64 ± 0.13) points, with the difference being significant (t=-4.071--2.541, P<0.05). The mature coping scores of the experimental group:problem solving, appealing were (0.70 ± 0.10), (0.67 ± 0.13) points, which were significantly higher than that of control group (0.63 ± 0.12), (0.58 ± 0.15) points and that of experimental group before the intervention (0.55 ± 0.12), (0.51 ± 0.11) points, with the difference being significant (t=2.308, 2.098, P <0.05). Conclusions Professional benefit recognition interventions can improve professional benefit recognition and stress coping style, is beneficial to nurses' physical and mental health and nursing quality.

Chinese Journal of Practical Internal Medicine 2001;0(05):-
Amyotrophic lateral sclerosis(ALS)is a progressive neurodegenerative disorder.Mutations in the Cu,Zn-superoxide dismutase(SOD1)gene cause ALS by an unknown gain-of-function mechanism.Current researches show that diminishing SOD1 mutation enzymatic activity does not account for motor neuron lose in ALS,while direct toxicity of variant SOD1 protein or aggregation of SOD1 protein may impart cell function and cause motor neuron death.Though motor neuron death is selective,other cells also participate in this course.The author reviewed recent advances in the relationship between mutant SOD1 and Amyotrophic Lateral Sclerosis.

Objective To understand the endemic characteristics and regularity of cystic echinococcosis by evaluating and classifying its endemic situation in Non Tibetan Plateau regions,so as to provide the evidence for formulating effective preventive and control measures. Methods The prevalence data of cystic echinococcosis in 174 counties(cities,districts,banners)in Non Tibetan Plateau regions from a national survey were collected and analyzed by the sample cluster method in 2012. Results The 174 counties(cities,districts,banners)could be classified into 4 clusters by spatial distribution. The first cluster with human high prevalence rate,low infection rate of livestock,and positive rate of dog stool antigen included 3 counties. The second cluster with high infection rate of livestock,low prevalence rate of human,and positive rate of dog stool antigen included 20 counties(cit-ies). The third cluster with high positive rate of dog stool antigen,low prevalence rate of human,and low infection rate of livestock included 39 counties(cities,districts,banners). The fourth cluster with low rates of the above 3 indices included the rest 112 counties. Conclusions The results of the cluster analysis conform to the current epidemiological status of cystic echinococcosis in the Non Tibetan Plateau regions. The epidemiological characteristics and geographical distributions of the four area types will pro-vide a basis for the classified management and guidance of cystic echinococcosis control in these areas.

Abstract Ion mobility spectrometry ( IMS) based explosives detectors is wieldy deployed at the check points of airport, etc, so the development of new ionization method to replace the radioactive 63 Ni ion source in IMS is highly demanded. In this study, a novel negative corona discharge was developed for ion mobility spectrometer for rapid detection of trace explosives, which was running in the unidirectional mode to efficiently remove nitrogen oxides and ozone produced from the discharge process. The diameter of target electrode was 3 mm, the distance between the needle and the target electrode was 2 mm, the discharge voltage was 2400 V and the flow rate of drift gas was 1200 mL/min. Under the optimized conditions, the dominant reactant ions was O-2(H2O)n and could be used to directly detect the common explosives, such as trinitrotoluene (TNT), ammonium nitrate (AN), nitroglycerin (NG), pentaerythritol tetranitrate (PETN) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). The limit of detection of TNT was 200 pg/μL. These results indicated that negative corona discharge ionization source, with the advantanges of the high sensibility, simple structure and no radioactivity, could be used as a potential and promising ionization source for ion mobility spectrometry to detect explosives.
