Objective To evaluate the therapeutic effect of thymosin alpha -1 with glucocorticoid in treat-ment of HBV -related hepatic failure.Methods 130 cases were randomly divided into two groups,they were all giv-en antiviral therapy,protect liver,anti -inflammatory,yellow suit the back support,etc.comprehensive treatment;and patients in treatment group were given thymosin alpha -1 with methyl -prednisone intravenously at the early stage of treating process,and then observed the clinic situation and cure rate of those sufferers,The biochemiccal indicator, PTA and blood serum HBV DNA capacity ending with the period of 4 weeks were tested.Results In both groups,the TBil,TC in serum had apparently improved compared with the baseline after the medication,the difference was signifi-cant (t =3.12,P <0.05 and t =3.05,P <0.05).The time of gastrointestinal symptoms improvement and bilirubin subsided time in treatment group were significantly shorter than those of the control group(t =3.34,P <0.01 and t =4.52,P <0.01 ).During the treatment,there was no significant adverse reaction,and there were no differences between two groups in Alt,PTA,HBV DNA,infection,gastrointestinal bleeding,hepatic encephalopathy and hepatore-nal syndrome.The effective rate of treatment group was 75.2%,which was higher than 50.3% of the control group (χ2 =11.02,P <0.01).Conclusion Patients with HBV -related hepatic failure of short -term application of thy-mosin alpha -1 with glucocorticoid treatment,can quickly improve symptoms,greatly improve the efficiency of survival rate,shortem hospitalization period,reduce side effects and enhance security.

OBJECTIVETo explore the relationship between nurse occupational stress and salivary alpha- amylase (SAA).

METHODSEvaluation of occupational stress was conducted in 131 nurses. The activity of SAA was determined using enzyme-linked immunosorbent assay (ELISA).

RESULTSThe activity of SAA in nurses varied with age and working years. The baseline, work period, recovery, average activities of >35 age group were less than those of ≤ 30 age group; work period, recovery, average activities of ≤ 10 years group were higher than other two groups; there was no statistical difference between SAA vitalities of different degree groups (P>0.05). In nurses with high scores for job demands, the activity of SAA in working period was significantly higher than that in nurses with low scores (P < 0.05). The baseline SAA activity in nurses with high scores for role conflict and ambiguity was significantly higherthan thatin nurses with low scores (P < 0.05). The baseline SAAactivity was positively correlated with workload, role conflict, and role ambiguity (P < 0.05). The activity of SAA in working period was negatively correlated with task control, decision control, and technology utilization (P < 0.05), and was positively correlated with quantitative load, load change, work monotony, and workload (P < 0.05). The activity of SAA in recovery period was negatively correlated with task control, decision control, resource control, and technology utilization (P < 0.01). The average activity of SAA was negatively correlated with task control, decision control, resource control, technology utilization, opportunity for participating in decision-making, and promotion (P < 0.05), and was positively correlated with quantitative load, load change, workload, and role ambiguity (P < 0.05).

CONCLUSIONThe occupational stress in 131 nurses is correlated with the activity of SAA, which can be used as an objective biomarker for identification and evaluation of occupational stress.

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.
