RESUMO
【Objective】 To explore the chain mediation model of psychological capital and coping efficacy on the relationship between organizational support and competence of university psychological commissioners. 【Methods】 We recruited 366 college psychological commissioners to complete the questionnaire survey regarding organizational support, competence of psychological commissary, psychological capital, and coping efficacy. 【Results】 ① Organizational support was positively correlated with the competence of psychological commissioners (r=0.61, P<0.01), psychological capital (r=0.59, P<0.01), and coping efficacy (r=0.57, P<0.01). The competence of psychological commissioners had a positive correlation with psychological capital (r=0.61, P<0.01) and coping efficacy (r=0.63, P<0.01). There was a positive correlation between psychological capital and coping efficacy (r=0.72, P<0.01). ② Psychological capital and coping efficacy had a chain mediating effect between organizational support and competence of psychological commissioners. The proportion of indirect effect was 43.76%. 【Conclusion】 Organizational support influences the competence of psychological commissioners, which can be predicted via the chain mediating path between psychological capital and coping efficacy.
RESUMO
Objective:To investigate the prognosis of severe hyperbilirubinemia in full-term infants who met the exchange transfusion criteria and were treated by blood exchange transfusion and phototherapy.Methods:A total of 168 full-term infants with severe hyperbilirubinemia who met the criteria for exchange transfusion and were hospitalized in the Neonatology Department of seven tertiary hospitals in Hebei Province from June 2017 to December 2018 were retrospectively included. According to the treatment protocol, they were divided into two groups: exchange transfusion group (38 cases) and phototherapy group (130 cases). Two independent sample t-test and Chi-square test were used to compare the clinical manifestations and follow-up results between the two groups. Multivariate logistic regression was used to analyze the risk factors for poor prognosis. Results:Neonatal severe hyperbilirubinemia in the exchange transfusion and phototherapy group were both mainly caused by hemolytic disease [42.1%(16/38) and 29.2%(38/130)], sepsis [28.9%(11/38) and 11.5%(15/130)] and early-onset breastfeeding jaundice [15.8%(6/38) and 11.5%(15/130)]. Total serum bilirubin level on admission in the exchange transfusion group was significantly higher than that in the phototherapy group [(531.7±141.3) vs (440.0±67.4) μmol/L, t=3.870, P<0.001]. Moreover, the percentage of patients with mild, moderate and severe acute bilirubin encephalopathy in the exchange transfusion group were higher than those in the phototherapy group [15.8%(6/38) vs 3.8%(5/130), 7.9%(3/38) vs 0.8%(1/130), 13.2%(5/38) vs 0.0%(0/130); χ2=29.119, P<0.001]. Among the 168 patients, 135 were followed up to 18-36 months of age and 12 showed poor prognosis (developmental retardation or hearing impairment) with four in the exchange transfusion group (12.9%, 4/31) and eight in the phototherapy group (7.7%, 8/104). Multivariate logistic regression analysis showed that for full-term infants with severe hyperbilirubinemia who met the exchange transfusion criteria, phototherapy alone without blood exchange transfusion as well as severe ABE were risk factors for poor prognosis ( OR=14.407, 95% CI: 1.101-88.528, P=0.042; OR=16.561, 95% CI: 4.042-67.850, P<0.001). Conclusions:Full-term infants who have severe hyperbilirubinemia and meet the exchange transfusion criteria should be actively treated with blood exchange transfusion, especially for those with severe ABE, so as to improve the prognosis.
RESUMO
Objective To explore the effect of gestational hypertension on multiple organ system in neonates. Methods A total of 100 newborns whose mother had pregnancy complicating primary hypertension admitted to our hospital from December 2011 to December 2012 were selected and divided into preeclampsia group (n=53), gestational hypertension group (n=47) according to the blood pressure during pregnancy. Meanwhile, 100 newborns with healthy mother were selected as control group including 12 term infants and 88 premature infants. Data including birth weight, length and head circumference, Apgar score, the percentage of amniotic lfuid pollution, placental abruption and fetal distress, Neonatal Behavioral Neurological Assessment (NABA) score, serum level of creatine kinase, pulmonary arterial pressure, thyroid function, blood glucose, blood routine, cranial MRI parameters were collected and compared among three groups. Results In preeclampsia group, the gestational age, birth weight and head circumference, 1-min and 5-min Apgar scores were lowest while the ratio of low birth weight infants was highest among three groups, and the differences were signiifcant (P<0.05). In preeclampsia group, the rates of antenatal abnormalities (amniotic lfuid meconium III degree pollution, placental abruption and fetal distress) and complications (severe infection, myocardial damage, neonatal polycythemia, liver and kidney damage, hypoglycemia, hypothyroidism and respiratory failure) were highest among three groups, and the differences were signiifcant (P<0.01). In preeclampsia group, the red blood cell count, the levels of hemoglobin, hematocrit and thyroid stimulating hormone were signiifcantly higher than those in the other two groups ( P<0.05 ), and the white blood cell and platelet count was signiifcantly lower than that in the control group (P<0.05). The passive muscle tension scores in preeclampsia group were signiifcantly lower than those in the other two groups (P<0.05).The abnormity rate of cranial MRI in preeclampsia group was highest among three groups, and the difference was signiifcant (P<0.01). Conclusions Gestational hypertension may cause multisystem disorders in newborns, such as fetal intrauterine growth restriction, endocrine system disorders, heart dysfunction, increased blood viscosity, delayed neurodevelopment. The severity of gestational hypertension is associated with the adverse impact on the multiple systems in neonates.
RESUMO
Objective To study normal imaging features of choroid fissure and to improve the ability of diagnosis of choroid fissureneuroepithelial cyst.Methods The MR manifestations of choroid fissure were studied by comparing general brain specimen with MR images of normal brains.The analysis of CT and MRI findings of choroid fissure neuroepithelial cysts in 14 cases were also conducted.Results The whole choroid fissure was clearly displayed as fissures full of cerebrospinal fluid on MRI.Cysts were shown round or ellapse foci with sharpmargins and homogeneous low density on CT or cerebrospinal fluid-like signal intensity on MRI.There was no enhanced contrast or nodramatic changes in follow-up studies.Conclusion The recognization of MR anatomy of choroid fissure and imaging manifestations ofchoroid fissure neuroepithelial cysts can improve the ability of diagnosis and differential diagnosis of cysts.
