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 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 test whether the constructed intervention model of advance care planning (ACP) for patients with advanced cancer can be successfully implemented and the preliminary intervention effect, which provides reference for empirical research.Methods:32 cases of advanced cancer patients and 25 cases of their families at the Fifth Affiliated Hospital of Zunyi Medical University, Zhuhai were selected. The patients were subdivided into the experimental group and the control group by random number table method. The control group received routine nursing, while the experimental group adopted the intervention model of "VIP for future care" on the basis of customary nursing. We measured the main outcome indicators: enrollment rate, consent rate, completion rate and loss of follow-up rate and secondary outcome indicators: decision-making certainty, end-of-life care preference and post-intervention satisfaction of patients and their families, within 1 week and 1 month after intervention.Results:The enrollment rate, consent rate and loss of follow-up rate were 74.6% (206/276), 36.9% (76/151)and 15.6% (5/32), respectively. After intervention, the completion rates of the experimental group and the control group were 16/16 and 15/16 within one week, and 14/16 and 13/16 within one month. All of the family members were conducted during the follow-up period. The intervention mode of "VIP for future care" had a statistically significant difference in decision-making certainty between the two groups of patients ( β=0.63, 95% CI 0.08-1.18, P<0.05), no statistically significant difference in end-of-life care preference between the two groups of patients and their families ( P>0.05), and had a statistically significant difference in "whether to recommend this project to others" between the two groups ( χ2 value was 4.167 , P<0.05). Conclusions:On the premise of sufficient preparation, the "VIP for future care" intervention mode can be successfully implemented in advanced cancer patients in mainland China, can improve the decision-making certainty of patients and the satisfaction of patients and their families, and it is recommended. And should be applied to ACP intervention for patients with advanced cancer.

Objective To explore the application effect of enteral nutrition-related diarrhea in postoperative esophageal cancer patients.Methods Based on literature search and expert meeting,a management process for enteral nutrition-associated diarrhea in postoperative esophageal cancer patients was constructed.A convenience sampling method was used to select a total of 68 patients with enteral nutrition-related diarrhea after esophageal cancer surgery admitted to the thoracic surgery department of a tertiary A cancer hospital in Jiangsu Province.Among them,patients admitted from January 2022 to December 2022 were set as an experimental group.The experimental group was implemented the management process for enteral nutrition-associated diarrhea in postoperative esophageal cancer patients.Those admitted from January 2021 to December 2021 were set as a control group with routine nursing.Then,the time of stopping diarrhea,the King's of Stool Chart(KSC-Tr)diarrhea score,and abnormal incidence of nutrition-related indexes,electrolytes abnormalities(low sodium,low potassium,and low calcium)were compared between 2 groups.Results The time of stopping diarrhea,KSC diarrhea score after 3 days of intervention and the time to achieve target feeding volume of the experimental group were lower than those in the control group,and the difference was statistically significant(P＜0.05).There were no significant differences in hemoglobin,albumin,prealbumin after 3 days of intervention,the incidence of electrolyte abnormalities(low sodium,low potassium,and low calcium)after 3 days of intervention,and the BMI index after 7 days of intervention between 2 groups(P＞0.05).Conclusion The management process for enteral nutrition-associated diarrhea in postoperative esophageal cancer patients can reduce the time of diarrhea,improve the severity of diarrhea,and shorten the time to achieve the target feeding,but has no significant change in the incidence of electrolyte abnormalities.

Relying only on the ethics committee to protect subjects is not enough, and the construction of the subject protection system is an inevitable trend for the protection of subjects’ rights. This paper elaborated on the current situation of Chinese subject protection system from four aspects: the lack of laws and regulations and administrative supervision, the insufficient attention of hospitals, poor construction of the subject protection system, and the absence of responsibilities of relevant personnel. Then this paper put forward countermeasures from three aspects: improving laws and regulations and strengthening supervision, mobilizing relevant departments to participate, and strengthening relevant training, in order to standardize the construction of the subject protection system and promote the development of the subject protection work.
