ABSTRACT
Objective:To study the correlation of serum tenascin C (TNC) and bronchopulmonary dysplasia (BPD) comorbid pulmonary hypertension (PH) in preterm infants.Methods:From January 2017 to June 2020, preterm infants (gestational age<32 weeks) diagnosed of severe BPD admitted to the Neonatal Intensive Care Unit of our hospital were prospectively studied. Comorbidity of PH was evaluated using echocardiography and the infants were assigned into PH (+) group and PH (-) group. At the same time, serum TNC was examined and the correlation between serum TNC level and PH in infants with severe BPD was analyzed.Results:A total of 59 infants with severe BPD were enrolled, including 21 cases comorbid PH (35.6%). The serum TNC level in the PH (+) group was significantly higher than the PH (-) group [(123.7±41.1) ng/ml vs. (78.2±20.2) ng/ml, P<0.05]. Correlation analysis showed a positive correlation between the serum TNC level and systolic pulmonary artery pressure (sPAP) ( r=0.861, P<0.001).The area under the receiver operating characteristic curve of serum TNC predicting BPD comorbid PH was 0.884. The sensitivity and specificity of serum TNC predicting BPD comorbid PH were 84.0% and 76.9% with TNC≥87.7 ng/ml as the cut-off. Conclusions:Severe BPD comorbid PH is common. The serum TNC level in infants with severe BPD comorbid PH is increased and positively correlated with sPAP. The serum TNC level has certain clinical value in predicting and evaluating the severity of BPD comorbid PH.
ABSTRACT
Objective To investigate the treatment and nursing of patients with pulmonary embolism after ovarian cancer combined with common variant immunoglobulin deficiency. Methods The clinical data of 1 case of acute pulmonary embolism after operation in a patient with ovarian cancer merger immunoglobulin defects were analyzed retrospectively. Results After the rescue patients, close observation of vital signs change, according to nursing bleeding and thrombosis, strengthen psychological support and other measures. The patient was discharged after 56 days of treatment and care. Conclusions The early detection of acute pulmonary embolism, timely diagnosis and treatment, close observation of vital signs, the nursing care of bleeding and thrombosis, in order to improve the success rate of treatment of acute pulmonary embolism.
