OBJECTIVETo investigate the correlation between nurse job burnout and salivary lysozyme activity.

METHODSThe saliva samples of 131 subjects were collected at four time points for two consecutive days with saliva collection tubes. The acquisition time points were 8:00 (baseline concentration), 10:00 (morning), 15:30 (afternoon), and 17:30 (recovery period). At the same time every subjects completed the job burnout questionnaire to investigate their general demographic characteristics and job burnout level. The salivary lysozyme concentration was measured with ELISA. The data were analyzed by partial correlation analysis and multiple stepwise regression analysis.

RESULTSThere were significant differences in the salivary lysozyme activity between subjects with different ages, working years, and education levels. The work period vitality and the average energy of ≤ 30 age group were higher than other two groups and the recovery energy was higher than >35 age group. Working period vitality, the average energy of group >15 years were less than ≤ 10 years group. The work period energy and the average energy of university (college) and above group were lower than high school (secondary) and the following group. Job burnout and its three dimensions had a significant negative correlation with salivary lysozyme concentration (P < 0.01). Depersonalization and emotional exhaustion were the negative impact factors for salivary lysozyme activity at baseline. Emotional exhaustion and personal fulfillment were the negative impact factors for salivary lysozyme activity during the working period. Personal fulfillment was the negative factor for salivary lysozyme activity during the recovery period and the average salivary lysozyme activity.

CONCLUSIONSalivary lysozyme activity is sensitive for nurse job burnout, so it can be used as an objective evaluation index of job burnout.

Objective: To explore the relationship between occupational stress and physiological and biochemical indexes, to research the health effect of the occupational stress in aircrew. Methods: 450 aircrews were conducted with the OSI-R questionnaire survey, examine the level of blood pressure, blood routine, ALT and UA. Results: The concentration of HB was positively related with task conflict and entertainment and leisure (β=0.262 and 0.106, both P<0.05) , while heavy task, task discomfort and psychological stress reactions were negatively related with HB (β=-0.163, -0.102, and -0.137, all P<0.05) ; task conflict and self-care were positively related with RBC (β=0.221 and 0.159, both P<0.01) , heavy task, psychological stress reactions and social support were negatively related with RBC (β=-0.157, -0.119, and -0.113, all P<0.05) ; task ambiguity and self-care had a positive relationship with ALT (β=0.144 and 0.159, both P<0.01) while heavy task, psychological stress reactions and social support had a negative relationship with ALT (β=-0.176, -0.096, and -0.102, all P<0.05) ; self-care was positively related with SBP (β=0.170, P<0.01) , task discomfort, interpersonal stress reactions and social support were negatively related with SBP (β=-0.093, -0.103, and -0.111, all P<0.05) ; while self-care was positively related with DBP (β=0.139, P<0.01) , social support was negatively related with DBP (β=-0.114, P<0.05) . Conclusion Occupational stress of the aircrew is significantly related with blood pressure, RBC, ALT and UA, occupational stress can make effects on the health of aircrew.

OBJECTIVETo investigate the effect of occupational stress on the oxidation/antioxidant capacity in nurses.

METHODSA total of 131 nurses were included as study subjects. The occupational health information collection system (based on the Internet of things) was used for measurement of occupational stress. Levels of hydroxyl free radicals and antioxidant enzymes were determined.

RESULTSThe serum level of superoxide dismutase (SOD) was the highest in nurses under the age of 30 and the lowest in those over 45 (P < 0.05). The serum levels of glutathione peroxidase (GSH-Px) and peroxidase (POD) were the highest in nurses of working age less than 5 years, followed by those of 5-15 years, and nurses with more than 25 years' working experience showed the lowest GSH-Px and POD levels (P < 0.05). Furthermore, nurses with a university (college) degree had a higher GSH-Px level and a lower POD level compared with those with junior and senior high school degrees (P < 0.05). Job prospects and job control were positive occupational stress factors for SOD. Job hazards were negative occupational stress factors for POD. Psychological satisfaction was negative occupational stress reaction for hydroxyl free radicals. Calmness was positive occupational stress reaction for SOD, and daily stress was a negative one. The positive occupational stress reactions for GSH-Px were psychological satisfaction and job satisfaction, and daily stress was negative reaction.

CONCLUSIONNurses with higher occupational stress have stronger oxidation and weaker antioxidant capacity, which intensifies oxidant-antioxidant imbalance and leads to oxidative stress damage.

OBJECTIVETo investigate the impact of occupational stress on serum monoamine neurotransmitters in nurses.

METHODSA total of 131 nurses were included as study subjects by stratified cluster sampling. The occupational health information collection system (based on the Internet of things) was used to measure occupational stress. Serum levels of monoamine neurotransmitters were also measured.

RESULTSEpinephrine (E) was negatively correlated with superior support (P < 0.05) and colleague support (P < 0.05). Negative correlation was also found between dopamine (DA) and job prospect (P < 0.05). Level of 5-hydroxytryptamine was negatively correlated with promotion opportunities (P < 0.05). Norepinephrine (NE), E, and DA were all negatively correlated with work satisfaction (P < 0.05) and positively correlated with daily stress (P < 0.01). NE and E were negatively correlated with sufficient confidence (P < 0.05) and positively correlated with physical complaints (P < 0.01). There was a negative correlation between NE and psychological satisfaction (P < 0.05).

CONCLUSIONOccupational stress in nurses is correlated with serum monoamine neurotransmitters, and it may affect serum levels of monoamine neurotransmitters to a certain extent.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

Virus infection induces the production of type I interferons (IFNs). IFNs bind to their heterodimeric receptors to initiate downstream cascade of signaling, leading to the up-regulation of interferon-stimulated genes (ISGs). ISGs play very important roles in innate immunity through a variety of mechanisms. Although hundreds of ISGs have been identified, it is commonly recognized that more ISGs await to be discovered. The aim of this study was to identify new ISGs and to probe their roles in regulating virus-induced type I IFN production. We used consensus interferon (Con-IFN), an artificial alpha IFN that was shown to be more potent than naturally existing type I IFN, to treat three human immune cell lines, CEM, U937 and Daudi cells. Microarray analysis was employed to identify those genes whose expressions were up-regulated. Six hundred and seventeen genes were up-regulated more than 3-fold. Out of these 617 genes, 138 were not previously reported as ISGs and thus were further pursued. Validation of these 138 genes using quantitative reverse transcription PCR (qRT-PCR) confirmed 91 genes. We screened 89 genes for those involved in Sendai virus (SeV)-induced IFN-β promoter activation, and PIM1 was identified as one whose expression inhibited SeV-mediated IFN-β activation. We provide evidence indicating that PIM1 specifically inhibits RIG-I- and MDA5-mediated IFN-β signaling. Our results expand the ISG library and identify PIM1 as an ISG that participates in the regulation of virus-induced type I interferon production.
