Objective To explore the status quo of and relevant contributing factors to Operating Room nurses' heat preservation nursing of perioperative patients.Methods According to phenomenological research in qualitative studies,totally 22 Operating Room nurses from a class Ⅲ grade A hospital in Xinjiang province were interviewed,and relevant data were analyzed and summarized based on Colaizzi Phenomenological Research and Nvivo 8.0.Results According to the analysis and summarization of the interview data,totally 5 factors affecting the status quo of perioperative heat preservation nursing were found,included theoretical awareness,occupational burnout,equipment configuration,quality control and doctor-nurse collaboration. Conclusions To prevent low body temperature during the operation and ensure patients' safety,managers should not only acquaint nurses with relevant nursing knowledge,but also optimize their management quality, strengthen humanistic care and focus on collaboration of the whole surgical team.

Objective To analyze the influencing factors of undergraduate nursing students′professional attitude in Xinjiang, so as to provide references for the educational guidance and decision-making management of nursing students′ professional attitude. Methods A questionnaire survey about professional attitude was conducted among 218 students of 2010-2013 full-time nursing students from Xinjiang Medical University and Shihezi University by convenience sampling method. Results The average score of nursing students′professional attitude was (3.80±0.67), which was in the “general” level. Univariate analysis showed that the professional attitude scores were significantly different among students with different gender, different choice, different parents′ education level, as well as whether they belong to one-child family ( P<0. 05 ) . Conclusions The professional attitude score of undergraduate nursing students was low. Nursing educators and administrators should implement targeted professional education, correct nursing students′ professional attitude, and keep the nursing team stable. Meanwhile, we also should retain talents and make good use of talents, so that to promote the sustainable development of nursing career.

Objective:To investigate the influence of the prevalence and co-prevalence of risk factors for metabolic syndrome on the scores of different levels of metabolic syndrome in people receiving physical examination in Urumqi.Methods:Using the 2017 Xinjiang Health Examination Database, a total of 175 927 people from 7 districts and 1 county in Urumqi were selected as subjects. Face-to-face survey and body measurements were used to collect cardiovascular risk factors and metabolic syndrome scores. Metabolic syndrome scores were used. For the 0-5 points at 6 levels, χ2, χ2 trend test, correlation analysis of ordered variable Kendall’s tau-b, and logistic regression analysis of ordered results were used to analyze the influence of prevalence and co-prevalence of behavioral risk factors on the MS scores. Results:The percentages of 6 metabolic syndrome scores in the sample population were 23.82 %, 27.87 %, 22.41 %, 16.03 %, 8.02 %, and 1.85 %, respectively. The scores of metabolic syndrome were different in different age groups, ethnic groups, groups with different drinking rates, and groups with different dietary types, with the differences all significant ( P<0.05).The MS score in men increased with the increase of oil/salt rate and excessive drinking rate ( P<0.01). The score in women increased with the increase of the current smoking rate, oil/salt rate, and increased with the decrease of physical activity ( P≤0.01). There was no significant difference in the distribution of regular drinking rates between different score groups ( P>0.05). The scores of metabolic syndrome increased with the increase of risk factors ( P<0.05). Ordered results logistic analysis found that in the men with ≥3 risk factors and the metabolic syndrome score was 1.15 (1.06-1.26) times higher than that in the men without risk factor, as well as in women with 2 risk factors and≥3 risk factors. The metabolic syndrome scores were 1.38 (1.22-1.55), 2.02 (1.53-2.66) times higher than those in the women without risk factors. Conclusions:The physical examination group in Urumqi, the more the metabolic syndrome disease behavior risk factors clustered, the higher the metabolic syndrome score was. Therefore, comprehensive intervention measures should be taken to control the different forms of metabolic syndrome to prevent the occurrence and progress of the disease.

Matching is a standard method for selecting research objects regarding the observational research, which controls confounding factors and improves statistical efficiency. However, its role in controlling confounding is not consistent in different observational studies. Matching can eliminate the confounding bias of matching variables in cohort studies, but checking on itself cannot eliminate confounding bias in case-control studies. In matched case-control studies, researchers may not accurately judge whether the variable is a confounder. Sometimes the variables that are not confounders are mistakenly matched. In that case, it will result in overmatching, which will lead to the decline of statistical efficiency or the introduction of unavoidable bias or increase of workload. If the real confounding factors are omitted, it will cause confounding bias. Therefore, researchers should consider what kind of matching variable selection criteria should be formulated. A directed acyclic graph is a visual graphic language that can show the complicated causality among different epidemiological research designs. This article analyzes the role of Matching in different observational research designs from the perspective of the directed acyclic graph, formulates the selection criteria for matching variables in matched case-control studies, and provides some reference suggestions for future epidemiological research design.
