Objective The purpose of this study was to explore the correlation between peripheral blood eosinophil (EOS) count and smoking history, some inflammatory indicators, lung function, efficacy of ICS, risk of respiratory failure and chronic pulmonary heart disease, risk of acute exacerbation within 1 year, readmission rate and mortality in patients with acute exacerbation of COPD. Methods Retrospective analysis of the baseline clinical data of 816 patients with acute exacerbation of chronic obstructive pulmonary disease in the Department of Respiratory and Critical Care Medicine of the First Affiliated Hospital of Shihezi University from January 1,2019 to December 31,2021. The patients were divided into EOS ≥ 200 cells / μL (High Eosinophi, HE) group and EOS<200 cells / μL (low Eosinophi, LE) group according to whether the peripheral blood EOS was greater than 200 cells / μL at admission. Peripheral venous blood data (including blood eosinophil count, white blood cell count, lymphocyte percentage, neutrophil percentage), blood gas analysis value, lung function index and medication regimen of all patients were collected, and the efficacy of ICS was recorded. The patients were followed up for 1 year to observe the acute exacerbation and readmission rate, and the mortality rate was followed up for 1 year and 2 years. Results Neutrophil count, lymphocyte count and peak expiratory flow (PEF) in HE group were positively correlated with EOS value (P<0.05), and smoking was more likely to increase EOS value. HE group was more sensitive to ICS. The risk of acute exacerbation in HEA group was higher than that in LE group. ICS could reduce the rate of acute exacerbation in HE group. EOS value in LE group was inversely proportional to FEV1 / FVC and MMEF values (P<0.05). The risk of chronic pulmonary heart disease in LE group was higher than that in HE group. The 2-year mortality rate in HE group was higher than that in LE group. Conclusions Peripheral blood EOS count is correlated with some inflammatory indicators, acute exacerbation risk, and lung function. ICS can improve the clinical symptoms and prognosis of patients with higher EOS count.
Objective
To evaluate the effects of inhalation combined intravenous antibiotics for the treatment of ventilator-associated pneumonia.
Methods
A computerized search was performed through Cochrane library, Joanna Briggs Institute Library, PubMed, MEDLINE, CINAHL, CBM, CNKI and Wangfang medical network about inhalation combined intravenous antibiotics therapy in ventilator-associated pneumonia in the literatures. The data extracting and quality assessment were performed by three researchers. The meta-analysis was performed by RevMan 5.3 software.
Results
Thirteen studies was included for analysis. The results showed that the cure rate was higher in the experimental group compared with the control group with significant difference (RR=1.16, 95%CI 1.07 to 1.56,P=0.000 5). There were no significant differences in the mortality (RR=1.04, 95%CI 0.82 to 1.32,P=0.74) or the incidence of kidney damage (RR=0.79, 95%CI 0.51 to 1.22,P=0.29). The difference in pathogenic bacteria removal was statistically significant (RR=1.38, 95%CI 1.09 to 1.74,P=0.007). The negative conversion rate of respiratory secretions was higher in the experimental group.
Conclusion
Inhalation combined intravenous antibiotics can improve the cure rate of patients with ventilator-associated pneumonia, clear pathogenic bacteria effectively, and is worthy of recommendation for clinical use.

Methods The clinical data of nine patients with endotracheal tubes prolapse after incision of trachea out of 158 patients suffering from incision of trachea for inhalation injury from January 2005 to March 2011 were retrospectively analyzed. Results The reasons of nine patients suffering from endotracheal tubes prolapse included tubes incongruity, severe cough, too slack bridles, insufficiency and break of aerocysts, too large incision and extraction by themselves. The prolapse time of nine patients was different. The shortest time was postoperative one day, the longest one was postoperative 15 days. Eight patients were treated emergently and healed normally. One patient died of long oxygen deficiency. Conclusions The reasons of endotracheal tubes prolapse after incision of trachea are sufficiently recognized. Predictable observing and nursing methods may decrease the incidence rate of tubes prolapse.
ObjectiveTo describe the imaging and clinical features of vaccinia virus induced pneumonia by long-term follow-up.MethodsThe clinical data, imaging features and long-term follow-up of 5 patients with vaccinia virus pneumonia admitted to Wuxi People's Hospital Affiliated to Nanjing Medical University were analyzed.ResultsAll the 5 patients were male, aged between 21 and 54 years. The latent period of the disease was 2 to 5 days. All the patients had fever and pneumonia, while 3 of them had herpes. Two patients with severe pneumonia showed extensive patchy and nodular shadows in both lungs. Chest CT findings of the other three patients showed scattered small nodules in both lungs. All patients were followed up by telephone every half a year for 3 years. The prognosis of all patients was good. The patients reported in the English literature were clinically clustered, with fever, vomiting and rash as the main symptoms.ConclusionsVaccinia virus may cause different clinical symptoms through different transmission routes, and its infectivity is strong. Biological protection should be strengthened in laboratory and working environment.
ObjectiveTo explore the hemodynamic effects of inhaled nitric oxide (iNO) on postoperative hemodynamic in patients with cyanotic congenital heart disease (CHD) combined with decreased pulmonary blood flow.MethodsFrom 2014 to 2018, there were 1 764 patients who received corrective repair of cyanotic CHD with decreased pulmonary blood flow in the Department of Pediatric Cardiac Surgery of Fuwai Hospital. We included 61 patients with the ratio of right ventricular systolic pressure to systolic blood pressure (SBP) ≥75% after weaning from cardiopulmonary bypass. There were 41 males and 20 females, with the age of 20.5 (9.0, 39.0) months and weight of 12.5±7.8 kg. The patients were divided into two groups: a conventional group (33 patients, conventional therapy only) and a combined therapy group (28 patients, iNO combined with conventional therapy). The hemodynamics during the first 24 hours after iNO therapy and the in-hospital outcomes of the two groups were investigated and compared.ResultsThere was no statistical difference between the two groups in demographic characteristics and surgical parameters (P>0.05). The hemodynamic effects of iNO within 24 hours included the decrease in the vasoactive inotropic score (VIS, 21.6±6.6 vs. 17.3±7.2, P=0.020) along with the increase in blood pressure (SBP: 73.7±9.7 mm Hg vs. 90.8±9.1 mm Hg, P<0.001) , the decrease in central venous pressure (10.0±3.1 mm Hg vs. 7.9±2.1 mm Hg, P=0.020), the decrease in lactate (2.2±1.7 mmol/L vs. 1.2±0.5 mmol/L, P<0.001) and increase in urine output [2.8±1.7 mL/(kg·h) vs. 4.9±2.2 mL/(kg·h), P<0.001]. The decrease of VIS at 24 h after the surgery in the conventional therapy group was not statistically significant (22.1±7.9 vs. 20.0±8.5, P=0.232). Besides, we discovered that the need for renal replacement therapy (RRT) was less in the combined therapy group than that in the conventional therapy group, especially in the moderate complicated surgery [risk adjustment in congenital heart surgery (RACHS-1) ≤3] subgroup (9.5% vs. 40.7%, P=0.016).ConclusionIn pediatric patients after corrective repair of cyanotic and pulmonary blood follow decreased CHD with increased pulmonary vascular resistance, iNO combined with conventional therapy can improve the hemodynamics effectively. Compared with the conventional therapy, the combined therapy with iNO can decrease the VIS and the need for RRT, which is beneficial to the postoperative recovery of patients.
ObjectiveTo retrospectively compare the clinical effects of high frequency oscillatory ventilation (HFOV) and conventional ventilation (CV) on patients with acute respiratory distress syndrome (ARDS) induced by smoke inhalation injury.
MethodsForty-three patients with smoke inhalation induced ARDS were admitted in the Center Hospital of Hu Ludao between October 2004 and June 2015.Among the patients, 19 cases were treated with CV (CV group) and 24 cases were treated with HFOV (HFOV group).The clinical data were collected and compared between two groups including blood gas at certain time points (6 h, 24 h, 48 h, 96 h, and 7 d) as well as complications and prognosis.
ResultsThere was no significant difference in arterial blood gas between two groups before treatment (P > 0.05).After ventilation treatment, there were significant differences in arterial blood gas parameters between two groups except arterial carbon dioxide partial pressure at 48 and 96 h.And the patients in the HFOV group improved more obviously.The hospitalization time and ventilation time in the HFOV group were significantly shorter than those in the CV group (P < 0.05).No significant difference was found between two groups in the incidences of mortality, complications or 30-day survival rate (P > 0.05).
ConclusionsBoth high frequency oscillatory ventilation and conventional ventilation can improve the clinical status in patients with smoke inhalation induced ARDS.These two ventilation modes do not present any difference with respect to prognosis by present evidence.
Objective To make an individualized treatment plan concerning a newborn with meconium aspiration syndrome combined with persistent pulmonary hypertension. Methods Based on the clinical questions raised by a newborn with meconium aspiration syndrome combined with persistent pulmonary hypertension, we searched The Cochrane Library (Issue 3, 2009), MEDLINE (1980 to June 2009), ACP Journal Club (1991 to June 2009), and Chinese Journal Fulltext Database (1994 to June 2009) for systematic reviews, randomized controlled trials (RCTs) and case-control studies. The quality of the included studies was assessed. Results A total of 9 RCTs, 1 health economic evaluation, 1 meta analysis, and 2 systematic reviews were considered eligible. The evidence indicated that the use of ECMO in infants of PPHN had shown a decreased risk of death, but not cost-saving from a societal perspective; iNO treatment could improve the PaO2 and resulted in a reduction in the incidence of requirement for ECMO; there were not randomized controlled trials regarding the treatment of PPHN by hyperventilation, high-frequency ventilation, alkali infusion, pulmonary vasodilators (magnesium sulfate, tolazoline, prostaglandin or prostacyclin, milrinone), surfactant therapy; oral sildenafil could lower oxygenation index (OI) and result in a reduction in the incidence of death. The individualized treatment plans of oral sildenafil were developed based on the available evidence, existing conditions of the hospital, and the values of children with families. After 1 month of treatment, the FiO2 returned to normal and symptoms were alleviated. Conclusion The treatment efficacies and the survival rates in meconium aspiration syndrome combined with PPHN have been improved by determining an individualized treatment plan according to evidence-based methods.
