Objective To investigate the effect of comprehensive nursing intervention and evaluate its role in the entire clinical course of in the treatment of children with severe burns. Methods A total of 60 children with 1-5 years old with clinical diagnosis of severe burns were randomly divided into experimental group and control group by random digits table method, 30 cases in each group. The control group received routine burn care. The experimental group received comprehensive nursing interventions on the basis of routine burn care and the intervention time covered the entire course of treatment. During hospitalization, the recovery and family social system were evaluated by anxiety scales and social support scales combined with the cure rate and hospitalization of children. Results Before intervention, the score of Anxiety Rating Scale was high in both groups of families, while Social Support Scale was lower, the difference was not statistically significant between the two groups (P>0.05). After intervention, the score of Anxiety Rating Scale and was Social Support Scale were (52.31±7.81), (31.52± 5.48)points in the experimental group, and (62.51 ± 6.52), (23.62 ± 5.62) points in the control group, and there were significant differences (t=5.491 3, 5.512 5, P<0.01). The length of stay was (18.34±3.58) d in the experimental group, and (21.82 ± 4.23) d in the control group, and there was significant difference(t=3.439 6, P<0.05). The cure rate was 93.33%(28/30) in the experimental group, and 56.67%(17/30) in the control group, and there was significant difference(χ2=10.755 6, P<0.05). Conclusions The comprehensive nursing intervention can provide comprehensive refinement of the overall care in children and their families, promote physical and psychological rehabilitation of children with severe burns, and repair their family and social support systems. The comprehensive nursing intervention has far-reaching implications for the rehabilitation of children with severe burns.

Objective: To explore the influences of comprehensive nursing intervention on the caregivers of severely burned children. Methods: Eighty severely burned children, admitted to our department from November 2016 to November 2017 and conforming to the study criteria, were included in this study. They were divided into comprehensive group and control group according to the random number table, with 40 children in each group. One caregiver for each child was included in the same group. Children and caregivers in control group had routine nursing care while children and caregivers in comprehensive group had comprehensive nursing care on the base of routine nursing care, including comprehensive psychological nursing of children and caregivers, guidance of rehabilitation for caregivers throughout the entire recovery process, individualized propaganda and education for caregivers on account of disease of children, perfecting social support system, sustained attention of children during follow-up. Anxiety self-rating scale and social support rating scale were used to assess the levels of anxiety and social support of caregivers of children in the two groups at the time of admission (before intervention) and the second month after discharge (the third time follow-up, after intervention). On the day of discharge, the nursing service satisfaction questionnaire of our department was used to evaluate the nursing service satisfaction of caregivers of children. Data were processed with chi-square test and independent sample t test. Results: (1) Before intervention, the anxiety and social support scores of caregivers of children in control group were respectively (64.5±3.8) and (40.4±2.5) points, similar to (63.5±4.9) and (40.5±2.6) points in comprehensive group (t=0.988, 0.177, P>0.05). After intervention, the anxiety score [(47.2±1.9) points] of caregivers of children in comprehensive group was significantly lower than that of control group [(57.6±4.3) points, t=13.917, P<0.01], and the social support score [(45.3±1.9) points] was significantly higher than (35.9±2.1) points in control group (t=-21.282, P<0.01). After intervention, scores of objective support, subjective support, and social support utilization in the social support evaluation rating of caregivers of children in comprehensive group were significantly higher than those in control group (t=12.678, -11.079, -10.031, P<0.01). (2) At the time of discharge, scores of clinical care, propaganda and education content and form in the nursing service satisfaction questionnaire of caregivers of children in comprehensive group were significantly higher than those of control group (t=-14.757, -15.627, -33.221, P<0.01). Conclusions Comprehensive nursing intervention method can effectively reduce the anxiety of the caregivers of severely burned children, help them to make better use of social support system, and improve the satisfaction of caregivers in nursing services.

M2 protein of influenza A virus is encoded by a spliced mRNA derived from RNA segment 7 and plays an important role in influenza virus replication. It is also a target molecule of anti-virus drugs. We extracted the viral genome RNAs from MDCK cells infected with swine influenza A virus (SIV) H3N2 subtype and amplified the SIV M2 gene by reverse transcriptase-polymerase chain reaction using the isloated viral genome RNAs as template. The amplified cDNA was cloned into a prokaryotic expression vector pET-28a(+) (designated pET-28a(+)-M2) and a eukaryotic expression vector p3xFLAG-CMV-7.1 (designated p3xFLAG-CMV-7.1-M2), respectively. The resulted constructs were confirmed by restriction enzyme digestion and DNA sequencing analysis. We then transformed the plasmid pET-28a(+)-M2 into Escherichia coli BL21 (DE3) strain and expressed it by adding 1 mmol/L of IPTG (isopropyl-beta-D-thiogalactopyranoside). The recombinant M2 protein was purified from the induced bacterial cells using Ni(2+) affinity chromatography. Wistar rats were immunized with the purified M2 protein for producing polyclonal antibodies specific for it. Western blotting analysis and immunofluorescence analysis showed that the produced antibodies were capable of reacting with M2 protein expressed in p3xFLAG-CMV-7.1-M2-transfected cells as well as that synthesized in SIV-infected cells. We also transfected plasmid p3xFLAG-CMV-7.1-M2 into Vero cells and analyzed its subcellular localization by immunofluorescence. The M2 protein expressed in the Vero cells was 20 kDa in size and dominantly localized in the cytoplasm, showing a similar distribution to that in SIV-infected cells. Western blotting analysis of SIV-infected cells suggested that M2 was a late phase protein, which was detectable 12 h post-infection, later than NS1, NP and M1 proteins. It would be a potential molecular indicator of late phases replication of virus. Our results would be useful for studying the biological function of M2 protein in SIV replication.

Objective:To explore the application effect of scenario infiltration joint interactive training mode for junior nurse training in the prevention and treatment of pressure sore.Methods:A total of 118 junior nurses starting to work in the First Affiliated Hospital of Air Force Medical University from July 2017 to July 2018 met the inclusion criteria and were divided into routine training (RT) group and scenario infiltration joint interactive training (SIJIT) group using the random number table for prospective randomized controlled trial. There were 2 males and 57 females, aged (23.9±1.2) years in RT group and 3 males and 56 females, aged (23.5±1.3) years in SIJIT group. Before the training, nurses in both groups received theory and practical tests for the prevention and treatment of pressure sore with a homemade theory test paper and operation requirements designed by the training group. The training content was drawn up in 3 themes according to the weak points shown in the test. Nurses in RT group were trained in a large classroom with the help of multimedia teaching technique, and one lesson of 2 h targeting one theme was given once a week.Nurses in SIJIT group were trained by using the SIJIT mode, with online self-study for 2 weeks and then multimedia theory and practical teaching, and interaction in scene. After the training, theoretical and practical tests were conducted again in nurses of two groups. Satisfaction scores of nurses for the training mode, training effect, and curriculum design and answers to open questions about the degree of training satisfaction were investigated through homemade questionnaire for satisfaction degree. Homemade training contents and requirements questionnaire designed by the training group was used to understand the demands of nurses for training contents and requirements in 2 groups. Data were statistically analyzed with chi-square test and independent sample t test. Results:(1) The theoretical and practical scores on the prevention and treatment of pressure sore before the training were (78±11) and (83±10) points respectively in RT group, similar to (79±11) and (84±10) points in SIJIT group ( t=0.522, 0.615, P>0.05). The theoretical and operational scores on prevention and treatment of pressure score of nurses after the training were (90±8) and (92±5) points in SIJIT group, significantly higher than (82±10) and (85±9) points in RT group ( t=4.581, 5.259, P<0.01). (2) The satisfaction degree scores for training mode, curriculum design, and training effect of nurses in SIJIT group were significantly higher than those in RT group ( t=5.169, 7.976, 4.463, P<0.01). Nurses in the 2 groups were satisfied with the curriculum content, and unsatisfied with the curriculum time and the ways of test. (3) The top demand of the training nurses for curriculum content was the treatment of phase Ⅱ-Ⅲ pressure sore, accounting for 81.36% (96/118). Conclusions:The SIJIT has flexible training mode, and reasonable curriculum design and content, which significantly improves the theoretical and operational levels on prevention and treatment of pressure sore of the training nurses and receives recognition of the training nurses.

At present, there are many monitoring devices for vital signs parameters for clinical selection, but urine monitoring has not received enough attention. The traditional manual visual measurement, intermittent measurement of urine pH value, and other methods are still in use, so the authors designed a multifunctional urine bag. The urine bag can set up an alarm system per unit time according to patient′s age and condition as well as set up urine pH value detection area in hard plastic measuring bottle. This device can not only accurately monitor urine volume per unit time, but also hopefully realize the alarm automation of abnormal urine volume per unit time, as well as real-time dynamic monitoring of urine pH value. It is helpful for medical staff to make accurate judgment on patients′ condition changes, to guide the formulation and modification of clinical treatment plans, and to reduce the workload of clinical nursing staff to a certain extent.

Objective: To explore the influence of cluster nursing intervention on inadequate drainage in vacuum sealing drainage (VSD) for inpatients in burn unit. Methods: From October to December 2016, 60 patients, aged (43.6±2.8) years admitted to our department, receiving VSD treatment and conforming to the inclusion criteria, were included in the routine nursing group, and among the patients, 37 cases were male and 23 cases were female. From May to July 2017, 58 patients, aged (44.2±3.2) years admitted to our department, receiving VSD treatment and conforming to the inclusion criteria, were included in the cluster nursing group, and among the patients, 36 cases were male and 22 cases were female. The patients′ medical records were retrospectively analyzed. After VSD treatment, patients in routine nursing group received routine nursing, and patients in cluster nursing group received cluster nursing. A cluster intervention group was formed and headed by a chief surgeon. The cluster nursing plan was formulated and implemented strictly from the following six aspects of material preparation, negative pressure value control and negative pressure mode setting, drainage tube nursing, semi-permeable membrane reinforcement, standardizing changing process and timing of drainage capsule, and health education. During VSD treatment, the incidence of inadequate drainage, reasons of inadequate drainage and the occurrences, occurrences of inadequate drainage of wounds in different types and sites, and satisfaction of patients in two groups were observed and calculated. The patient satisfaction items included procedure of drainage capsule replacement, the method of tube fixation, the content and form of health education. Data were processed with independent sample t test and chi-square test. Results: (1) During VSD treatment, the incidence of inadequate drainage of patients in routine nursing group was 43.33% (130/300), which was significantly higher than 17.24% (50/290) in cluster nursing group (χ²=43.350, P<0.01). (2) During VSD treatment, the incidences of inadequate drainage caused by blockage of drainage tube due to scabbing of drainage, low negative pressure, air leakage of semi-permeable membrane, improper changing process of drainage capsule, shedding, compression, reversal of drainage tube of patients in cluster nursing group were 7.93% (23/290), 4.48% (13/290), 1.72% (5/290), 1.03% (3/290), and 2.07% (6/290), respectively, significantly lower than 16.67% (50/300), 11.67% (35/300), 4.33% (13/300), 4.00% (12/300), and 6.67% (20/300) in routine nursing group (χ²=10.379, 22.951, 4.832, 7.840, 7.399, P<0.05 or P<0.01). (3) During VSD treatment, the incidences of inadequate drainage of burn wounds, trauma wounds, pressure ulcer, venous ulcer in lower limbs, and diabetic foot of patients in cluster nursing group were significantly lower than those in routine nursing group (χ²=17.835, 6.809, 9.478, 4.939, 8.631, P<0.05 or P<0.01). During VSD treatment, the incidences of inadequate drainage of wounds in different types of patients in the same group were close (χ²=0.434, 0.057, P>0.05). (4) During VSD treatment, the incidences of inadequate drainage of wounds in limbs, trunk, buttocks, and sacrococcyx of patients in cluster nursing group were significantly lower than those in routine nursing group (χ²=31.892, 9.588, 4.939, 4.549, P<0.05 or P<0.01). During VSD treatment, the incidences of inadequate drainage of wounds in different wound sites of patients in the same group were close (χ²=0.071, 0.069, P>0.05). (5) The satisfaction scores in changing process of drainage capsule, method of tube fixation, content and form of health education of patients in cluster nursing group after VSD treatment were significantly higher than those in routine nursing group (t=5.166, 4.471, 7.958, 8.975, P<0.01). Conclusions Cluster nursing intervention on patients receiving VSD treatment could reduce the incidences of inadequate drainage of wounds in different types and sites caused by various reasons. It also can improve patient satisfaction.
