Objective To investigate the clinical efficacy and its security on different kinds of atomization with mucosolvan and chymotrypsin in treating neonatal pneumonia.Methods Seventy-eight neonates who were diagnosed as neonatal pneumonia were divided into treatment group (n =39) and control group (n =39) by random number table method from Jul 2011 to Aug 2013 in our hospital.The control group was treated with chymotrypsin atomization,and the treatment group was treated with compression atomizing to inhale mucosolvan.The treatment effects of two groups were compared.Results Compared with the control group after treatment for 24 h,48 h,72 h,the treatment group had more significant increasing in PaO2,more decreasing in PaCO2 and more significant improvement in oxygenation index.There were statistical significances between the two groups(P ＜ 0.01).The treatment group spent shorter time in remission of symptoms,disappear of signs and hospital stay than that of the control group(P ＜ 0.05).In the treatment group,25 cases were markedly improved,9 cases were effective,5 cases were invalid.The effective rate was 87.2％.In the control group,14 cases were markedly effective,6 cases were effective,19 cases were invalid.The effective rate was 51.3％.The effective rate was significant difference between the two groups (P ＜ 0.01).The adverse drug reactions were not found in the process of treatment for two groups.Conclusion Mucosolvan atomizing inhalation has a better treatment effect than chymotrypsin.It can shorten the course of treatment,and is worth promoting the application.

Objective To investigate the predictive value of neutrophil to lymphocyte ratio(NLR),platelet to lymphocyte ratio(PLR),and the simplified pulmonary embolism index(sPESI)score for 30-day death in patients with acute pulmonary embolism(APE).Methods The clinical data of 291 APE patients admitted to Xuanwu Hospital of Capital Medical University from January 2017 to December 2021 were retrospectively analyzed.White blood cell count(WBC),NLR,PLR,sPESI score,and other indicators were calculated at admission.The patients were followed up within 30 days and were divided into the death group and the survival group accord-ing to the prognosis.The differences in the above indexes between the two groups were compared.Multivariate Logistic regression was used to analyze the independent risk factors for 30-day mortality in APE patients.The area under the receiver operating characteristic(ROC)curve of NLR,PLR,and combined sPESI scores in predicting mortality was compared.Results Among the APE patients,11 cases(3.78％)died and 280 cases(96.22％)survived within 30 days.The WBC,NLR,PLR,and sPESI score in the death group were sig-nificantly higher than those in the survival group(P＜0.05).Multivariate Logistic regression analysis showed that PLR,NLR,and sPESI score were independent risk factors for 30-day mortality in APE patients(P＜0.05).The area under ROC curve(AUC)of PLR in pre-dicting the 30-day death of APE patients was 0.799(P=0.001).The AUC of NLR was 0.827(P=0.001).The AUC of sPESI score was 0.874(P=0.001).There was no significant difference in the AUC of PLR,NLR,and sPESI score in predicting death(P=0.181,0.340);the AUC of NLR combined with sPESI score was 0.925(P=0.001),which was greater than that of NLR(P=0.004).The AUC of PLR combined with sPESI score was 0.901(P=0.001),which was greater than that of PLR(P=0.002).Conclusion NLR,PLR,and sPESI score are independent risk factors for 30-day mortality in APE patients,and all of them have certain prognostic values.The prognostic value of PLR and NLR combined with sPESI score was higher than that of PLR and NLR alone.
