Objective
To Assess the efficacy of using lung ultrasound to guide alveolar recruitment maneuver in patients with acute respiratory distress syndrome (ARDS).
Methods
Sixty patients with ARDS were randomly divided into two groups, ie, maximal oxygenation group (n=30) and lung ultrasound group (n=30). All the patients had artificial airway and needed mechanical ventilation. The patients in the two groups accepted recruitment maneuver guided by maximal oxygenation or lung ultrasound respectively. During the course of recruitment maneuver, the arterial partial pressure of oxygen (PaO2), positive end-expiratory pressure (PEEP), central venous pressure (CVP), mean arterial pressure (MAP), cardiac output (CO), and extravascular lung water index (EVLWI) were recorded and compared between both groups.
Results
The PaO2 in lung ultrasound group was higher than that in maximal oxygenation group (P=0.04). The PEEP was higher in lung ultrasound group but without significant difference (P=0.910). There was no significant difference of the other outcomes (CVP, MAP, CO, EVLWI) between the two groups (all P>0.05).
Conclusion
Lung ultrasound is an effective means that has good repeatability and security for guiding recruitment maneuver in patients with ARDS.
Objective
To investigate the correlation between the initial arterial blood lactic acid and Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score in trauma patients and its value in prognosis.
Methods
From August 1st 2015 to July 31st 2016, the clinical data of trauma patients treated in Department of Emergency were analyzed retrospectively. All patients were divided into survival group and death group by observing 28-day prognosis. We compared the relationship between the initial blood lactate level and APACHEⅡ score, and analyzed the relationship between the above indexes and the prognosis of the patients.
Results
A total of 743 patients were enrolled, with692 in survival group and 51 in death group.The APACHEⅡ score and initial blood lactate level in the survival group [(9.93±4.62) points, (2.02±1.44) mmol/L] were significantly lower than those in the death group [(22.84±7.26) points, (4.60±3.69) mmol/L] with significant differences (t=18.20, 9.77; P<0.01). The APACHEⅡ score and the mortality rate of patients with lactic acid level >4 mmol/L were significantly higher than those of patients with lactic acid of 2-4 mmol/L and <2 mmol/L; the differences were significant (P<0.05). The blood lactate and mortality in patients with APACHEⅡ score >20 were significantly higher than those in the patients with ≤10 and 11-20; the differences were significant (P<0.05). There was a significant positive correlation between initial blood lactate level and APACHEⅡ score (r=0.426, P<0.01).
Conclusions
The initial blood lactate level and APACHEⅡ score of trauma patients are correlated with the severity of injury and mortality. Both of the increase of initial blood lactic acid level and APACHEⅡ score suggest the risk of death in trauma patients.
Objective To explore the possible anti-inflammatory mechanism of intensive insulin therapy （IIT） by studying the effect of IIT on the levels of TNF-α, IL-6, C-reactive protein （CRP） and APACHE Ⅱ score in biliary pyemia. Methods Twenty eight patients with biliary pyemia who were admitted by our department and given an operation within 24 h form Jan. 2005 to Dec. 2008 were randomly divided into two groups by using random number table numbers: one group treated with IIT （IIT group, n=14） and another group treated with routine insulin therapy （RIT group, n=14）. The inflammatory factors, such as TNF-α, IL-6 and CRP were detected dynamically and the APACHEⅡ score was calculated. ResultsThe level of CRP and APACHEⅡ score on day 5 and 7 and the levels of TNF-α and IL-6 on day 3, 5 and 7 after operation in IIT group were significantly lower than those in RIT group （P＜0.05, P＜0.0１）. Compared with preoperative levels, the IL-6 and APACHEⅡ score in IIT group commenced to decrease on day 3 after operation （P＜0.05）, that was earlier than control group. Conclusion The treatment with IIT can suppress the composition of TNF-α, IL-6 and CRP, protect impaired hepatic cells, and reduce APACHEⅡ score, the degree of systemic inflammation and incidence of MODS.

ObjectiveTo analyze the roles of three scoring systems, i.e. Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ, Ranson’s criteria, and Sequential Organ Failure Assessment (SOFA), in predicting mortality in patients with severe acute pancreatitis (SAP) admitted to intensive care unit (ICU), and explore the independent risk factors for mortality in SAP patients.MethodsThe electronic medical records of SAP patients who admitted to ICU of West China Hospital, Sichuan University between July 2014 and July 2019 were retrospectively analyzed. Data of the first APACHE Ⅱ, Ranson’s criteria, SOFA score, duration of mechanical ventilation, the use of vasoactive drugs and renal replacement therapy, and outcomes were obtained. The receiver operator characteristic (ROC) curve was used to evaluate the value of APACHE Ⅱ score, Ranson’s criteria, and SOFA score in predicting the prognosis of SAP. Logistic regression models were created to analyze the independent effects of factors on mortality.ResultsA total of 290 SAP patients hospitalized in ICU were screened retrospectively, from whom 60 patients were excluded, and 230 patients including 162 males and 68 females aged (51.1±13.7) years were finally included. The ICU mortality of the 230 patients with SAP was 27.8% (64/230), with 166 patients in the survival group and 64 patients in the death group. The areas under ROC curves of APACHE Ⅱ, Ranson’s criteria, APACHE Ⅱ combined with Ranson’s criteria, and SOFA score in predicting mortality in SAP patients admitted to ICU were 0.769, 0.741, 0.802, and 0.625, respectively. The result showed that APACHE Ⅱcombined with Ranson’s criteria was superior to any single scoring system in predicting ICU death of SAP patients. The result of logistic regression analysis showed that APACHE Ⅱ score [odds ratio (OR)=1.841, 95% confidence interval (CI) (1.022, 2.651), P=0.002], Ranson’s criteria [OR=1.542, 95%CI (1.152, 2.053), P=0.004], glycemic lability index [OR=1.321, 95%CI (1.021, 1.862), P=0.008], the use of vasoactive drugs [OR=15.572, 95%CI (6.073, 39.899), P<0.001], and renal replacement therapy [OR=4.463, 95%CI (1.901, 10.512), P=0.001] contributed independently to the risk of mortality.ConclusionsAPACHE Ⅱ combined with Ranson’s criteria is better than SOFA score in the prediction of mortality in SAP patients admitted to ICU. APACHE Ⅱ score, Ranson’s criteria, glycemic lability index, the use of vasoactive drugs and renal replacement therapy contribute independently to the risk of ICU mortality in patients with SAP.
ObjectiveTo establish the gene-based esophageal cancer (ESCA) risk score prediction models via whole transcriptome analysis to provide ideas and basis for improving ESCA treatment strategies and patient prognosis.MethodsRNA sequencing data of esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC) and adjacent tissues were obtained from The Cancer Genome Atlas database. The edgeR method was used to screen out the differential genes between ESCA tissue and normal tissue, and the key genes affecting the survival status of ESCC and EAC patients were initially identified through univariate Cox regression analysis. The least absolute shrinkage and selection operator regression analysis and multivariate Cox regression analysis were used to further screen genes and establish ESCC and EAC risk score prediction models.ResultsThe risk score prediction models were the independent prognostic factors for ESCA, and the risk score was significantly related to the survival status of patients. In ESCC, the risk score was related to T stage. In EAC, the risk score was related to lymph node metastasis, distant metastasis and clinical stage. The constructed nomogram based on risk score showed good predictive ability. In ESCC, the risk score was related to tumor immune cell infiltration and the expression of immune checkpoint genes. However, this feature was not obvious in EAC.ConclusionThe ESCC and EAC risk score prediction models have shown good predictive capabilities, which provide certain inspiration and basis for optimizing the management of ESCA and improving the prognosis of patients.
ObjectiveTo study the relationship between preoperative pan-immune-inflammation value (PIV), preoperative hemoglobin, albumin, lymphocyte and platelet score (HALP) and tumor pathological features and microsatellite status of colorectal cancer, and to analyze the predictive value of HALP and PIV for microsatellite status. MethodsThe clinicopathological data of 156 patients who underwent radical colorectal cancer resection admitted to the Second Hospital of Shanxi Medical University from May 2021 to February 2024 were retrospectively analyzed. HALP and PIV were calculated by preoperative related laboratory indicators, and then the patients were divided into high HALP/low HALP (HHALP/LHALP) group (n=78) and high PIV/low PIV (HPIV/LPIV) group (n=78) according to the median of their calculated values. The correlation between preoperative HALP and PIV and clinicopathologic features of colorectal cancer was analyzed. According to the results of microsatellite stability detection, the patients were divided into microsatellite standard/microsatellite instability-high（MSS/MSI-H）group. The correlation between preoperative HALP and PIV and microsatellite stability was analyzed. The predictive value of HALP and PIV for microsatellite status was analyzed by using receiver operating characteristic (ROC) curve. ResultsThere were statistically significant differences in tumor diameter, tumor location, HALP, T stage and microsatellite status between the HPIV group and the LPIV group (P<0.05), and high PIV was more common in patients with right-sided colon cancer and MSI-H, and the tumors were larger and had higher T stage. The differences in gender, body mass index（BMI）, tumor diameter, tumor location, PIV, T stage and microsatellite status between the HHALP group and the LHALP group were statistically significant (P<0.05), and low HALP was more common in women, patients with right-sided colon cancer, and MSI-H, and had a low BMI, large tumors, and high T stage. There were statistically significant differences in HALP and PIV between MSS group and MSI-H group (P<0.05), and patients with MSI-H tended to have low HALP and high PIV, and the area under curve of HALP and PIV in predicting MSI-H for colorectal cancer was 0.848 9 and 0.851 6, respectively, and the optimal cut-off value was 26.84 scores and 507.04, respectively, and the sensitivity was 1.000, 0.923, specificity 0.643, 0.817, respectively. ConclusionLow HALP and high PIV are more common in patients with right-sided colon cancer and MSI-H, who have poor nutritional and immune status, severe inflammation, larger tumors, deeper invasion, and predictive value for MSI-H, which can assist in the formulation of clinical treatment plans to a certain extent.
ObjectiveTo investigate the effects of subxiphoid uniportal video-assisted thoracoscopic surgery (SUVATS) and intercostal uniportal VATS (IUVATS) in lobectomy for non-small cell lung cancer (NSCLC).MethodsA total of 428 patients with NSCLC who underwent lobectomy via SUVATS or IUVATS from July 1st to 31st, 2019 in Shanghai Pulmonary Hospital were enrolled. Patient characteristics, perioperative outcomes and postoperative pain scores at different time points were collected. The patients were divided into a SUVATS group (80 patients, 42 males and 38 females with an average age of 58.8±9.6 years) and an IUVATS group (348 patients, 161 males and 187 females, with an average age of 61.2±10.0 years). The clinical effectiveness of the two groups was compared.ResultsThere was no significant difference in sex (P=0.314), age (P=0.052), preoperative pulmonary function (P=0.701), combined chronic comorbidities (chronic cardiovascular disease, P=0.775; chronic obstructive pulmonary disease, P=0.678) and postoperative pathology (P=0.132) between the two groups. Compared with the IUVATS group, patients in the SUVATS group had longer operation time (155.6±34.4 min vs. 141.3±27.0 min, P<0.001), less intraoperative blood loss (165.2±160.6 mL vs. 223.7±272.4 mL, P<0.001), shorter time of chest tube use (4.3±2.0 d vs. 4.9±1.9 d, P=0.011) and less postoperative pain score at different time points (postoperative 8 h, P<0.001; postoperative day 1, P=0.019; postoperative day 2, P=0.015; the day before discharge, P<0.001).ConclusionSUVATS is a safe and effective technique for lobectomy in NSCLC patients with less postoperative pain and can promote postoperative recovery.
Objective To investigate the influence of pulmonary infection on noninvasive ventilation ( NIV) therapy in hypercapnic acute respiratory failure ( ARF) due to acute exacerbation of chronic obstructive pulmonary disease ( AECOPD) , and evaluate the predictive value of simplified version of clinical pulmonary infection score ( CPIS) for the efficacy of NIV therapy in ARF patients with AECOPD. Methods Eighty-four patients with ARF due to AECOPD were treated by NIV, and were divided into a successful group and an unsuccessful group by the therapeutic effect of NIV. The CPIS and simplified version of CPIS between two groups was compared. The predictive value of simplified version of CPIS for the efficacy of NIV wasevaluated using ROC curve analysis. Results The CPIS and the simplified version of CPIS of the successful treatment group ( 4. 0 ±2. 8, 3. 2 ±2. 4) were lower than those of the unsuccessful group ( 8. 0 ±2. 1, 7. 2 ±1. 8) significantly ( P =0. 006, 0. 007) . The area under ROC curve ( AUC) of CPIS and simplified version of CPIS were 0. 884 and 0. 914 respectively, the cut oint of CPIS and simplified version of CPIS were 6 ( sensitivity of 78. 0% , specificity of 91. 2% ) and 5 ( sensitivity of 80. 0% , specificity of 91. 2% ) respectively. Conclusions The level of pulmonary infection is an important influencing factor on the therapeutic effect of NIV in patients with ARF due to AECOPD. Simplified version of CPIS is a helpful predictor for the effect of NIV on ARF of AECOPD.
Objective To compare surgical outcomes of Stanford type A acute aortic dissection between operations at midnight and daytime. Methods From January 2004 to March 2013，195 patients with Stanford type A acute aortic dissection received surgical treatment in Nanjing Hospital Affiliated to Nanjing Medical University （Nanjing Cardiovascular Disease Hospital）. Patients with identical or similar propensity scores were matched from 127 patients who underwent emergency operation at daytime and 68 patients who underwent emergency operation at midnight. A total of 58 pairs of matched patients which had the same or similar propensity score were selected in daytime surgery group （n=58，43 males and 15 females，47.7±14.6 years） and midnight surgery group （n=58，45 males and 13 females，48.3±14.6 years）. Operation time，postoperative chest drainage，mechanical ventilation time，postoperative incidence of dialysis and tracheostomy，length of ICU stay and in-hospital mortality were compared between the daytime group and midnight group. Results A total of 58 pair of patients were matched in this study. There was no statistical difference in postoperative incidence of tracheostomy ［19.0% （11/58） vs. 6.9% （4/58），P=0.053］ or in-hospital mortality ［8.6% （5/58） vs. 6.9%（4/58），P=0.729］ between the midnight group and daytime group. Operation time （485.7±93.5 minutes vs. 428.5±123.3 minutes，P=0.048），postoperative chest drainage （979.5±235.7 ml vs. 756.6±185.9 ml，P=0.031），mechanical ventilation time （67.9±13.8 hours vs. 55.7±11.9 hours，P=0.025），postoperative incidence of dialysis ［17.2% （10/58） vs. 5.2%（3/58），P=0.039］ and length of ICU stay （89.4±16.2 hours vs. 74.8±12.5 hours，P=0.023） of the midnight group weresignificantly longer or higher than those of the daytime group. A total of 107 patients were followed up for 4-6 months after discharge. During follow-up，there was no late death. Among the 13 patients who required postoperative dialysis，12 patientsno longer needed regular dialysis. Conclusion Emergency operation at midnight does not increase in-hospital mortalitybut increase some postoperative morbidity in patients with Stanford type A acute aortic dissection. Whether at midnight or daytime，better preoperative preparation and surgeons’ vigor are needed for timely surgical treatment for patients with Stanford type A acute aortic dissection.
