The update of multi-omics technology is a key means to promote the rapid development of accurate health model in the whole life cycle.It can formulate dynamic and accurate nursing measures and provide massive data information from the perspective of nursing biology of health and disease.At present,clinical nursing research faces many challenges such as insufficient application and transformation ability of multi-omics technology.This paper introduces the multi-omics technology,reviews the application status of multi-omics technology in cancer nursing,maternal and child nursing,chronic metabolic disease nursing and symptom management,and puts forward the cross integration and prospect of multi-omics technology and nursing research,so as to strengthen the information mining ability of nurses at different levels of health and disease,and provide an important basis for accelerating the clinical transformation of precision nursing.

Objective:To investigate the predictive efficacy of global inhomogeneity (GI) index based on pulmonary electrical impedance tomography (EIT) in postoperative pulmonary infection of patients with craniocerebral trauma.Methods:A total of 90 patients with emergency craniocerebral trauma underwent surgery under general anesthesia in Suzhou Science & Technology Town Hospital. According to the complication of pulmonary infection at the 3rd day after operation, they were divided into the pulmonary infection group (P3 group) and non-pulmonary infection group (NP3 group), and according to the complication of pulmonary infection at the 7th day after operation, they were divided into the P7 group and NP7 group. The average GI index within 5 min before anesthesia induction (T 0) and 5 min after endotracheal intubation (T 1) and other clinical data in the perioperative period were collected. The prevalence of pulmonary infection at the 3rd and 7th days after operation was recorded. Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of preoperative GI index for pulmonary infection at the 3rd and 7th days after operation. Results:A total of 88 patients were included. Among them, 26 patients developed pulmonary infection within 3 days after operation, and the prevalence rate was 29.5%. Pulmonary infection occurred in 38 patients within 7 days after operation, and the prevalence rate was 43.2%. Within 3 days after operation, the preoperative Glasgow Coma Scale score in the P3 group was significantly lower than that in the NP3 group ( P < 0.05). Within 3 days after operation, GI index in the P3 group increased significantly at T 1 when compared with the NP3 group ( P< 0.001). Within 7 days after operation, GI index in the P7 group increased significantly at T 1 when compared with the NP7 group ( P < 0.05). GI index at T1 accurately predicted pulmonary infection within 3 days after operation (AUC = 0.857, P < 0.001), and the best intercept value was ≥0.4225 (sensitivity: 0.846, specificity: 0.823). GI index at T 1 predicted pulmonary infection within 7 days after operation (AUC = 0.667, P < 0.005), and the best intercept value was ≥0.4225 (sensitivity: 0.579, specificity: 0.780), but the prediction efficiency was poor. Conclusions:The average GI index within 5 min after endotracheal intubation can be used as an effective predictor of pulmonary infection within 3 days after operation.

Objective:To explore the effect of mild cognitive impairment on the subjective well-being of the elderly and the mediating role of self-efficacy in it. To provide an effective basis for health management and clinical intervention in the elderly with mild cognitive impairment.Methods:A total of 164 patients with mild cognitive impairment from December 2018 to June 2019 were surveyed by the General Self-efficacy Scale, the Montreal Cognitive Assessment Scale, and the Memorial University of Newfoundland Scale of Happiness Scale.Results:The overall score of self-efficacy was 21.41±3.98, and subjective well-being was 26.44±7.35. There was a positive correlation among cognitive function, self-efficacy and subjective well-being, except that there was no significant correlation between self-efficacy and cognitive function( r values were 0.263-0.687, P<0.01). Self-efficacy played a part in mediating between cognitive function and subjective well-being in patients with mild cognitive impairment, accounting for 37.8% of the total effect. Conclusions:Mild cognitive impairment can also have a negative impact on the subjective well-being of the elderly. Among them, self-efficacy plays a particularly important role in mediating. Interventions about self-efficacy on the elderly with mild cognitive impairment may have more significant effects.

Objective:To explore the influence of mindfulness meditation intervention on the professional identity and turnover tendency of the second victim of nurses.Methods:The convenience sampling method was used to select the second victim of 46 nurses who experienced medical adverse events within six months from January to June 2019 in Zhongnan Hospital of Wuhan University, and then an 8 weeks of mindfulness meditation intervention was carried out for them. In the entire intervention process, a self-control study was conducted, the Second Victim Experience and Support Scale (SVSET) and the Nurse Occupational Identity Scale were used to assess nurses' turnover intentions, absence and professional identity before the intervention and at 2 hours, 4 weeks, and 8 weeks after the intervention.Results:By analyzing the data, the results showed that after the mindfulness meditation intervention, the second victim of the nurse before intervention, 2h, 4 weeks, and 8 weeks of intervention were 3.28±0.87, 3.20±0.83, 2.85±0.92, 2.71±0.87, the difference was statistically significant ( F time value was 6.609, P<0.05). Before and after the intervention of the sense of grasp in professional identity were 4.91±0.83, 5.47±0.81, 5.83±0.91, 5.94±0.80, the difference was statistically significant ( F time value was 20.973, P<0.01). Consensus before and after intervention were 4.61±0.78, 5.09±0.85, 5.54±1.12, 5.76±0.85, the difference was statistically significant ( F time value was 22.237, P<0.01). The meaningful sense before and after intervention were 4.38±1.03, 5.04±0.75, 5.44±0.86, 5.59±0.76, the difference was statistically significant ( F time value was 23.656, P<0.01). The self-efficacy before and after intervention were 4.71±0.82, 5.33±0.63, 5.83±0.84, 5.90±0.77, the difference was statistically significant ( F time value was 28.866, P<0.01). The self-determination before and after intervention were 4.43±0.97, 5.06±0.81, 5.59±0.91, 5.62±0.87, the difference was statistically significant ( F time value was 25.237, P<0.01). Before and after intervention, the influence of tissue was 4.17±0.96, 4.71±0.85, 4.96±0.99, 5.30±0.88, the difference was statistically significant ( F time value was 16.487, P<0.01). Before and after intervention, the patients' feelings were 4.59±0.96, 5.08±0.84, 5.70±0.83, 5.83±0.68, the difference was statistically significant ( F time value was 25.406, P<0.01). Conclusion:This article provides an effective method to help nurses' second victims out of their predicament which confirms that mindfulness meditation intervention can effectively reduce turnover tendency of nurses 'second victims and improve their professional identity.

Objective:To investigate the clinical effect of laparoscopic assisted removal of greater omentum free transplantation combined with skin grafting for the repair of large area refractory wounds.Methods:From June 2013 to June 2018, 18 cases of lower extremity skin and soft tissue defects with multiple bone, joint, tendon and internal plants exposure were admitted to Hanzhong Central Hospital, including 12 males and 6 females, aged from 15 to 50 years old, with an average age of 32.6 years old. The area of skin and soft tissue defect: 30 cm×12 cm-53 cm×21 cm. The operation was divided into two stages. In the first stage, the greater omentum was acquired with the assist of laparoscope and free transplanted to cover the wound. After the greater omentum free transplantation was confirmed to survive, the split-thickness skin graft was applied for wound repair.Postoperative survival of the greater omentum and skin grafting, complications, appearance and function of lower limbs were observed and followed up.Results:The 18 operations were performed successfully, the area of omentum resection was 25 cm×10 cm-35 cm×15 cm, all the greater omentums survived after operation without complications such as intestinal adhesion, volvulus and peritonitis. The area of the skin grafting was 36 cm×8 cm-45 cm×22 cm. 16 cases skin grafting survived completely, 2 cases skin grafting were necrosis just local small area, and scar healed after dressing change. Postoperative follow-up of 6-12 months showed good appearance and function of lower limbs and satisfactory results.Conclusions:For the large area soft tissue defect wound of lower extremity, complicated with multiple deep tissues such as bone, joint and internal materials exposed, the greater omentum free transplantation under laparoscope combined with medium thick skin graft second stage has the advantages of good appearance and function after wound healing, less donor injury and fewer postoperative complications.

Objective:To evaluate the obesity factor on ventilator-induced lung injury (VILI) in rats.Methods:Forty-five clean-grade male Sprague-Dawley rats, aged 6-8 weeks, were divided into 3 groups ( n = 15 each)according to the body weight: normal weight control group (group C), normal weight VILI group (group CV) and obese VILI group (group FV). The body weight was 233-267 g in C and CV groups and 288-332 g in FV group.In group C, the tidal volume (V T) was 10 ml/kg.In CV and FV groups, the rats were ventilated for 4 h with the V T set at 40 ml/kg, respiratory rate 40 breaths/min, inspiratory/expiratory ratio 1∶2, PEEP 0 mmHg, and fraction of inspired oxygen 21% to establish the VILI model.The arterial blood samples were collected immediately before tracheal intubation and at 4 h of mechanical ventilation for blood gas analysis and PaO 2 recording.The remaining blood samples were used for plasma collection.The rats were sacrificed after blood collection at 4 h of ventilation, and the bilateral lung tissues were isolated to collect the bronchoalveolar lavage fluid (BALF). The concentrations of leptin in plasma and tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β) and interleukin-6 (IL-6) in plasma and BALF were detected by enzyme-linked immunosorbent assay.The wet/dry weight (W/D) ratio of lung tissues was measured.The pathological changes of lung tissues were observed after HE staining, and the lung injury score was evaluated.The expression of NF-κB p65 in lung tissues was detected by Western blot. Results:Compared with group C and group CV, the plasma leptin concentration was significantly increased in group FV( P<0.01). Compared with group C, the concentrations of TNF-α, IL-6 and IL-1β in plasma and BALF were significantly increased, PaO 2 was decreased, the lung injury score and W/D ratio of lung tissues were increased, and NF-κB p65 expression was up-regulated at 4 h of ventilation in CV and FV groups ( P<0.01). Compared with group CV, the concentrations of TNF-α, IL-6 and IL-1β in plasma and BALF were significantly decreased, PaO 2 was increased, the lung injury score and W/D ratio of lung tissues were decreased, and NF-κB p65 expression was down-regulated at 4 h of ventilation in group FV ( P<0.05). Conclusion:Obesity factor can reduce VILI in rats, and the mechanism may be related to the increase in plasma leptin levels.

Objective To investigate the level about illness perception in patients with coronary heart disease. Methods From July to De-cember, 2015, 198 inpatients with coronary heart disease who were admitted into hospitals twice or more were enrolled. They were assessed with Illness Perception Questionnaire-Revised (IPQ-R). Results The score of common symptoms was (4.55±1.64). The symptoms, for exam-ple, chest pains, uncomfortable feeling in chest, cold sweat, flustered and breathlessness were most frequently experienced and most often identified. For the illness perception part, the scores on subscales of treatment control and consequences were higher than 3, which was the neutral point. For the cause dimension part, the highest scores was (3.38 ± 0.90) in diet or eating habits, followed by (3.38 ± 0.89) in aging. Among these factors, immune factors had the highest mean score, followed by stress factor. Conclusion The level of illness perception in pa-tients with coronary heart disease was in the middle level, and individual differences were obvious. The awareness of the disease and the in-tervention of the patient should be strengthened.

The secondary prevention of coronary heart disease is one of the fundamental strategies of preventing and controlling coronary heart disease, and its effectiveness and necessity have been widely demonstrated. However, the clinical practice is incompatible with the guideline, and patients′ compliance is unsatisfactory because clinical medical members pay more attention to the rescue and treatment of cardiovascular disease after acute onset rather than the prevention and rehabilitation. Thus, a deep understanding of the compliance of secondary prevention for coronary heart disease needs to be focused, in order to identify the influence factors and come up with effective strategies. This paper aims to conclude the evidences of improving patients′ compliance according to literature review and to guide the secondary prevention of coronary heart disease in clinical practice.

Objective To explore the effects of home-based 6-minute walk test on self-management in patients after percutaneous coronary intervention (PCI). Methods Eighty-four patients who admitted for PCI in the past five years in Cardiovascular Medicine of Zhujiang Hospital of Southern Medical University were recruited from the three major communities and were divided into intervention group and control group by random digits table method with 42 cases each. The intervention group had the home-based 6-minute walk test and monthly telephone follow-up while the control group was followed up by telephone and keep daily activities. Six months after the intervention,the changes of chronic disease self-management in-ventory were compared. Results There were significant differences the overall health self-assessment, fa-tigue,chest pain, time of aerobic exercise, the increase of self-efficacy between intervention group and control group[ (0.62±1.28) points vs. (0.20±1.71) points, (-0.84±3.27) points vs. (0.36±2.71) points, (0.04 ±3.56) points vs. (0.34 ±3.56) points, (30.47 ±123.29) min/week vs. (6.62 ±84.82) min/week, (0.42±3.01) points vs. (-0.29±2.94) points ], and there were significant differences, F=9.15, 7.42, 5.24, 3.91, 12.18, P<0.01. But there were no significant differences for other 9 aspects between two groups (P>0.05). Conclusions Home-based 6-minute walk test can be a simple self-assessment tool used at home for patients after PCI.
