Purpose: This study aimed to identify the relationship between job complexity, infection prevention environment, and nursing intention for patients with emerging infectious diseases, with a focus on the mediating effect of job crafting in hospitals dedicated to coronavirus disease 2019 (COVID-19). Methods: The study surveyed 202 nurses with at least 3 months of work experience who encountered COVID-19 patients at a dedicated COVID-19 hospital. The collected data were analyzed using IBM SPSS/WIN 25.0, and the mediating effect was analyzed through the SPSS PROCESS macro, using regression analysis. Results: It was demonstrated that job crafting fully mediated the relationship between job complexity and nursing intention for patients with emerging infectious diseases. Furthermore, this study showed that job crafting partially mediated the relationship between infection prevention environment and nursing intention for patients with emerging infectious diseases. Conclusion It was confirmed that job crafting of nurses in a hospital dedicated to COVID-19 was an important mediating factor in their nursing intention for patients with emerging infectious diseases, and this finding is expected to support efforts to further improve nursing intention for patients with emerging infectious diseases.

Objective To evaluate the function of motor nerve in patients with diabetic sensory neuropathy (DPN) by estimating the motor units.Methods Fifty-four patients with DPN were divided into two groups according to the nerve conduction abnormality of ulnar nerve.The paresthosia group only included patients of 33 patients (20 male, 13 female) with abnormal sensory conduction.The admixture group included 21 patients (13 male, 8 female) with abnormal motor sensory conduction.The control group included 42 healthy people.A Keypoint4 electromyogram device was used to estimate the motor units of hypothenar muscle, and the fasting blood glucose and the duration of diabetes mellitus were documented.Results The motor units of hypothenar muscle in paresthesia group, admixture group and control group was 97.1±47.6, 63.3±22.3, 173.0±75.5 (F=21.259, P=0.000) respectively.The hypothcnar muscle motor units(84.0±42.8) in 54 patients with DPN had negative correlation (r=-0.414, P=0.002) with the duration of diabetes mellitus (1 month to 26 years) and had no evident correlation with fasting blood glucose (5.0-20.4 mmol/L).Conclusion There is clinical motor nerve damage in patients with diabetic sensory neuropathy, and the loss of motor units is impacted by the duration of diabetes mellitus.

Objective:To investigate the characteristics of phrenic nerve motor conduction (PNC)and motor evoked potentials of diaphragm elicited through magnetic stimulation (dMEP)in mechanical ventilation of patients with chronic obstructive pulmonary disease(COPD).Methods:PNC and dMEP were performed in 10 COPD patients with regular mechanical ventilation(the duration of mechanical ventilation≤7 d),10 COPD patients with prolonged mechanical ventilation(the duration of mechanical ventilation＞7 d),and 10 healthy subjects(control group).Results:There were significant differences in the latency and the common logarithm of the amplitude of PNC,cervical dMEP and cortical dMEP between three groups before and after weaning(P＜0.01 or P＜0.05).There were significant differences in central motor conduction time(CMCT)in three groups before and after weaning(P＜0.01).There was longer CMCT before weaning in two COPD groups than that of control group(P＜0.01).It showed no statistical difference in CMCT before weaning between two COPD groups(P＞0.05).There was a longer CMCT after weaning in prolonged mechanical ventilation than that of regular mechanical ventilation(P＜0.01).However,there was no statistical difference in CMCT after weaning between the regular mechanical ventilation group and the control group(P＞0.05).Conclusion:There were dysfunctions in the cortico-diaphragmatic pathway in COPD patients with mechanical ventilation,which may be aggravated by the prolonged mechanical ventilation.PNC and dMEP may help to define the cause of respiratory dysfunction in COPD patients with mechanical ventilation.

BACKGROUND:Using experimental animals to simulate diseases of human being is the basis of studying etiology and treatment of the diseases, so the diseases of nasal cavity and sinus need suitable experimental animals as models.
OBJECTIVE:To observe the regional anatomy of rhino-sinus in rabbits and its performance through CT imaging, and to discuss the feasibility of applying a rabbit model to the study of animal rhino-sinusitis.
METHODS:Routine coronal and axial scanning images of rhino-sinus of New Zealand rabbits were performed through Discovery CT750 HD. The rhino-sinus anatomy was then observed.
RESULTS AND CONCLUSION:The nasal septum is located on both sides of the nasal cavity. The lateral wal of rabbit nasal is composed of maxil ary turbinate, middle turbinate, the inside of the middle turbinate and inferior turbinate. The maxil ary sinus cavity is the largest one and ethmoid sinus, sphenoid sinus and frontal sinus are relatively much smal er. Al these sinuses are paired and symmetrical. The rhino-sinus in rabbit is displayed clearly in CT scan. The anatomical location of rabbit is similar to that of human;however, the maxil ary sinus of rabbit is greater than that of human correspondingly, which is suitable for operating and applying to surgical anatomy and imaging analysis. The rabbit model of rhino-sinus can be applied to simulate human rhino-sinusitis.

PURPOSE: The Perinatal Post-Traumatic Stress Disorder Questionnaire (PPQ) was designed to measure post-traumatic symptoms related to childbirth and symptoms during postnatal period. The purpose of this study was to develop a translated Korean version of the PPQ and to evaluate reliability and validity of the Korean PPQ. METHODS: Participants were 196 mothers at one to 18 months after giving childbirth and data were collected through e-mails. The PPQ was translated into Korean using translation guideline from World Health Organization. For this study Cronbach's alpha and split-half reliability were used to evaluate the reliability of the PPQ. Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and known-group validity were conducted to examine construct validity. Correlations of the PPQ with Impact of Event Scale (IES), Beck Depression Inventory II (BDI-II), and Beck Anxiety Inventory (BAI) were used to test a criterion validity of the PPQ. RESULTS: Cronbach's alpha and Spearman-Brown split-half correlation coefficient were 0.91 and 0.77, respectively. EFA identified a 3-factor solution including arousal, avoidance, and intrusion factors and CFA revealed the strongest support for the 3-factor model. The correlations of the PPQ with IES, BDI-II, and BAI were .99, .60, and .72, respectively, pointing to criterion validity of a high level. CONCLUSION: The Korean version PPQ is a useful tool for screening and assessing mothers' experiencing emotional distress related to child birth and during the postnatal period. The PPQ also reflects Post Traumatic Stress Disorder's diagnostic standards well.

Objective To observe the clinical efficacy of acupoint sticking plus hot compress by moxa-salt bag in treating constipation after acute cerebral stroke.Method Eighty patients with constipation after cerebral stroke were randomly allocated to a treatment group and a control group by using random number table method according to registration order, 40 cases each. The control group was intervened by acupoint sticking at umbilicus with rawDa Huang (Rheum Officinale), and the treatment group was additionally given hot compress using moxa-salt bag. The treatment was given once a day, for consecutive 3 days in total. The first defecation time, stool shape and defecation sensation were observed in the two groups. The clinical efficacies were compared between the two groups.Result The total effective rate was 90.0％ in the treatment group versus 72.5％ in the control group, and the difference was statistically significant (P<0.05). After the treatment, there was statistically significant difference in comparing the first defecation time between the two groups (P<0.05). After the treatment, the incidence rate of soft stool was 85.0％ and that of hard stool was 15.0％ in the treatment group versus 40.0％ and 60.0％ in the control group, and the differences were statistically significant (P<0.05). The incidence rate of pleasant defecation sensation was 80.0％ and that of difficult defecation was 20.0％ in the treatment group versus 35.0％ and 65.0％ in the control group after the treatment, and the differences were statistically significant (P<0.05).Conclusion Acupoint sticking plus hot compress by moxa-salt bag is an effective method in treating constipation after acute cerebral stroke.

Purpose: This study examined the eating-out patterns of Korean infants and school-aged children and compared diet quality. Methods: Data were obtained from the 2016–2018 Korea National Health and Nutrition Examination Survey. The subjects were 306 children aged 3 to 11 years old that ate dinner at restaurants. Percentage energy intakes of 24 food groups were calculated, and cluster analysis was used to identify eating-out patterns. Diet quality was assessed by calculating percentage energy and nutrient intakes using one-third of the 2015 Dietary Reference Intakes for Korean (KDRIs), nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ). Results: Cluster analysis identified 2 eating-out patterns, that is, a ‘rice-centered’ (53%) and a ‘mixed diet’ (47%) pattern. For those with the mixed diet pattern, ratios of carbohydrates, protein, and fat to total calories were 48:20:31, whereas for the rice-centered pattern, ratios were 62:15:21 (p < 0.001). Intakes of energy and most nutrients in the mixed diet pattern were excessive, but the intakes of the most nutrients in the rice-centered pattern were much lower than their KDRIs. MARs were higher for the mixed diet pattern than the rice-centered pattern (0.74 vs. 0.66) (p < 0.001), and INQs for vitamin C (p = 0.007) and calcium (p = 0.018) were lower for the rice-centered pattern, whereas INQ for iron (p = 0.003) was lower for the mixed diet pattern. Conclusion The quality of meals for infants and school-aged children depended on eating-out patterns, but the rice-centered and mixed diet patterns both failed to provide an appropriately balanced meal pattern. The results of this study suggest that healthy menus need to be developed for children in restaurants.

This study aimed to explore the impact of depression caused by chronic unpredictable mild stress (CUMS) on in vivo activity of six kinds of CYP450 isoforms in rats. According to 'Katz' method, the model of CUMS was established. Tolbutamide, chlorzoxazone, theophylline, midazolam, omeprazole and dextromethorphan were chosen as probe substrates of CYP2C6, CYP2E1, CYP1A2, CYP3A2, CYP2D1 and CYP2D2 of rats. Plasma concentration of six kinds of CYP450 in control group and model group were determined by LC-MS/MS and computed pharmacokinetic parameters. Consequently, metabolism of theophylline and chlorzoxazone accelerated significantly (P < 0.01), but tolbutamide, dextromethorphan, omeprazole and midazolam had no significant difference. The present study proved that depression caused by CUMS had strong induction to CYP1A2 and medium induction to CYP2E1.
