ABSTRACT
Objective:To investigate the epidemiological characteristics of septic cardiomyopathy and explore the relationship between the relevant indexes measured by echocardiography and the prognosis of patients with sepsis.Methods:A case-control study was conducted. The data of patients with sepsis admitted to the department of critical care medicine of Jiangsu Subei People's Hospital Affiliated to Yangzhou University and the department of critical care medicine of Beijing Electric Power Hospital of State Grid Corporation of China from June 2018 to June 2021 were enrolled. The general information and 28-day prognosis were recorded. At the same time, ultrasonic parameters obtained by transthoracic echocardiography within 24 hours after intensive care unit (ICU) admission were recorded. The differences in ultrasound indexes between the death group and the survival group on 28 days were compared. Parameters with significant statistical differences between the death group and the survival group were included in the Logistic regression analysis to find the independent risk factors for the prognosis of patients with sepsis, the predictive value of each index for the prognosis of patients with sepsis was evaluated by receiver operator characteristic curve (ROC curve).Results:A total of 145 patients with sepsis were enrolled, including 106 patients with septic shock. Among the 145 patients, septic cardiomyopathy was found in 73 patients, with the incidence of 50.3%. The incidence of left ventricular diastolic dysfunction cardiomyopathy was 41.4% ( n = 60), the incidence of left ventricular systolic dysfunction cardiomyopathy was 24.8% ( n = 36), and the incidence of right ventricular systolic dysfunction cardiomyopathy was 12.4% ( n = 18). At 28 days, 98 patients survived and 47 died, with the mortality of 32.4%. The peak e' velocity by tissue Doppler imaging (e') and right ventricular myocardial systolic tricuspid annulus velocity (RV-Sm) of the death group were significantly lower than those of the survival group [e' (cm/s): 7.81±1.12 vs. 8.61±1.02, RV-Sm (cm/s): 12.12±2.04 vs. 13.73±1.74, both P < 0.05], left ventricular ejection fraction (LVEF) and left ventricular systolic mitral annulus velocity (LV-Sm) in the death group were slightly higher than those in the survival group [LVEF: 0.550±0.042 vs. 0.548±0.060, LV-Sm (cm/s): 8.92±2.11 vs. 8.23±1.71], without significant differences (both P > 0.05). Parameters with significant statistical differences between the two groups were included in the Logistic regression analysis and showed that e' and RV-Sm were independent risk factors for the 28-day prognosis of patients with sepsis [e': odds ratio ( OR) = 0.623, 95% confidence interval (95% CI) was 0.410-0.947, P = 0.027; RV-Sm: OR = 0.693, 95% CI was 0.525-0.914, P = 0.010]. ROC curve analysis showed that the area under the ROC curve (AUC) of e' for predicting the 28-day prognosis of patients with sepsis was 0.657, 95% CI was 0.532-0.781, P = 0.016, the best cut-off value was 8.65 cm/s, the sensitivity was 62.1%, and the specificity was 73.4%. The AUC of RV-Sm for predicting the 28-day prognosis of patients with sepsis was 0.641, 95% CI was 0.522-0.759, P = 0.030, the best cut-off value was 14.80 cm/s, the sensitivity was 96.6%, and the specificity was 26.6%. Conclusions:The incidence of septic cardiomyopathy is high. The LVEF measured by early echocardiography has no predictive value for 28-day prognosis in septic patients, while RV-Sm and e' are important predictors for 28-day prognosis.

ABSTRACT
Objective To explore the expression of ANLN in HCC and study the clinical value of ANLN expression for HCC patients after liver transplantation.Methods The protein and mRNA expression of ANLN was detected by immunohistochemistry and RNA-seq from TCGA respectively.Chi-square test and t test were used for correlation analysis between ANLN expression and clinicopathological characteristics.The predictive value of ANLN expression for HCC patients after liver transplantation was estimated by log-rank test and cox proportional hazards regression model.Results The positive protein expression rate of ANLN in HCC detected by immunohistochemistry was 37.0％ (34/92),significantly higher than 6.5 ％ (6/92) in para-carcinoma non-tumor tissue (P＜0.001,x2 =25.044).Upregulation of ANLN mRNA expression in HCC was also detected by the analysis of RNA-seq from the TCGA (P ＜ 0.000 1).The positive ANLN protein expression was positively correlated with AFP＞400 ng/L (P＜0.001,x2 =11.952) and tumor size ＞8 cm (P =0.034,x2 =4.506).The independent risk factors for poorer 5-year survival of patients after liver transplantation were confirmed,including positive ANLN protein expression (P =0.031,OR =1.965,95 ％CI =1.064-3.630),tumor size ＞8 em (P =0.003,OR =2.841,95 ％CI =1.437-5.617),worse differentiation degree (P =0.001,OR =3.613,95％ CI =1.646-7.928),peritumor intravascular cancer emboli (P =0.041,OR =1.896,95％CI =1.028-3.498) and tumor necrosis or hemorrhage (P=0.010,OR=2.195,95 ％CI=1.211-3.979).Conclusion The expression of ANLN in HCC is upregulated and the positive protein expression indicates the poor prognosis for long-term survival of patients after liver transplantation.
ABSTRACT
Objective To study the incidence of acute renal injury ( AKI), related clinical risk factors and recent prognosis in critically ill neonates. Methods The study was a retrospective analysis from January 2016 to December 2016 in the neonatal care department of General Hospital of Shenyang Military Region and the First Hospital Affiliated to China Medical University. We collected the perinatal data,clinical data,biochemical indexes and short-term prognosis. Logistic regression analysis was used to identify the risk factors. Results The incidence of AKI in critically ill neonates was 13. 11%(32/244),and the probability of poor prognosis was 62. 50%(20/32). Gestational age,birth weight,1 min and 5 min Apgar score,con-sciousness,mechanical ventilation,blood pH,blood glucose,blood urea nitrogen,white blood cell and red cell distribution width were the related factors for AKI in critically ill neonates. Logistic regression analysis showed that consciousness(OR=4. 542,95%CI 1. 176-17. 539,P=0. 028),mechanical ventilation(OR=0.267,95%CI 0.101-0.705,P = 0.008),5 min Apgar score(OR = 0.750,95% CI 0.605-0.930,P =0. 009),blood urea nitrogen value(OR=1. 074,95%CI 1. 006-1. 146,P=0. 030)were identified as the inde-pendent risk factors of AKI. ConclusionThe incidence of AKI is high in critically ill neonates. Consciousness,mechanical ventilation,5 min Apgar score,blood urea nitrogen value are identified as independent risk factors for AKI.
ABSTRACT
@#Objective To explore the risk factors and short-term clinical effect of conversion to open thoracotomy during thoracoscopic lobectomy for lung cancer patients. Methods We retrospectively analyzed the clinical data of 423 lung cancer patients who were scheduled for thoracoscopic lobectomy between March 2011 and November 2015.There were 252 males and 171 females at median age of 60 (24-83) years. According to the patients who were and were not converted to thoracotomy, they were divided into a conversion group (378 patients) and a video-assisted thoracic surgery group (a VATS group, 45 patients). Then, clinical data of two groups were compared, and the risk factors and short-term clinical effect of unplanned conversions to thoracotomy were analyzed. Results Lymph nodes of hilar or/and interlobar fissure closely adhered to adjacent vessels and bronchi was the most common cause of unexpected conversions to thoracotomy in 15 patients (33.3%), followed by sleeve lobectomy in 11(24.4%) patients, uncontrolled hemorrhage caused by intraoperative vessel injury in 8 patients, tumor invasion or extension in 5 patients, difficulty of exposing bronchi in 3 patients, close adhesion of pleural in 2 patients, incomplete interlobar fissure in 1 patient. Conversion did translate into higher overall postoperative complication rate (P=0.030), longer operation time (P<0.001), more intraoperative blood loss (P<0.001). In the univariable analysis, the type of operation, the anatomical site of lung cancer, the lymph node enlargement of hilar in CT and the low diffusion capacity for carbon monoxide (DLCO) were related to conversion. Logistic regression analysis showed that the independent risk factors for conversion were sleeve lobectomy (OR=5.675, 95%CI 2.310–13.944, P<0.001), the lymph node enlargement of hilar in CT (OR=3.732, 95%CI 1.347–10.341, P=0.011) and DLCO≤5.16 mmol/(min·kPa)(OR=3.665, 95%CI 1.868–7.190, P<0.001). Conclusions Conversion to open thoracotomy during video-assisted thoracic surgery lobectomy for lung cancer does not increase mortality, and it is a measure of reducing the risk of surgery. Therefore, with high-risk patients who may conversion to thoracotomy, the surgeon should be careful selection for VATS candidate. And, if necessary, the decision to convert must be made promptly to reduce short-term adverse outcome.
ABSTRACT
Objective To identify the risk factors of the incidence rate of initial poor graft function (IPGF)in recipients after living donor liver transplantation. Methods Clinical data of 309 patients undergoing living donor liver transplantation were retrospectively analyzed.

Single factor analysis was performed to identify the potential risk factors of IPGF. Logistic regression analysis was conducted to explore independent risk factors. Results and Conclusions Child-Pugh C of preoperative recipient liver function,MELD score≥20,serum total bilirubin elevation(>68. 4μmol/L),hyponatremia(<1 35 mmol/L), hypopotassaemia (<3. 5 mmol/L)and anhepatic phase≥1 00 min were potential risk factors of IPGF (all P<0. 05 ). Child-Pugh C of preoperative recipient liver function was an independent risk factor of the incidence rate of IPGF following living donor liver transplantation (P=0. 01 9).
ABSTRACT
Objective To investigate the risk factors of post-ERCP pancreatitis( PEP). Methods Data of 4,234 patients who underwent ERCP in Nanjing Drum Tower Hospital were retrospectively analysed. Information of patients and operations,including age,gender,operation history,major disease history,labora-tory examination before operation,abdominal ultrasound,CT,MRCP,detailed ERCP operation process,com-plications and treatment were carefully recorded. Then Chi-square test was used for univariate analysis,and stepwise multivariate Logistic regression for variate analysis. Linear correlations between risk factors were de-tected. Results There were totally 226 PEPs,with 5. 3% incidence rate. Univariate analysis showed that the female(χ2 =9. 715,P=0. 002),young( <60 years)(χ2 =6. 108,P=0. 013),chronic pancreatitis(χ2 =14. 703,P=0. 001),initial ERCP(χ2 =14. 899,P=0. 000),hypertension(χ2 =4. 489,P=0. 034),nor-mal bilirubin levels before operation(χ2 =19. 159,P =0. 000 ),difficult cannulation(χ2 =45. 824,P =0. 000),pancreatic guide wire(χ2 =30. 223,P=0. 000),papillary pre cut(χ2 =45. 928,P=0. 000),pan-creatography(χ2 =20. 170,P=0. 000)may be risk factors for PEP. Non conditional Logistic regression analy-sis showed that female(OR=1. 449,P=0. 011),initial ERCP(OR=1. 745,P=0. 003),normal bilirubin levels before operation(OR=1. 917,P=0. 000),difficult cannulation(OR=3. 317,P=0. 000)and pancre-atography(OR=1. 823,P=0. 004)were independent risk factors for PEP. Linear correlation analysis sugges-ted that pancreatic duct guide wire and papillary precut were related to the difficult cannulation,and the corre-lation coefficients were -0. 788 and -0. 699. Conclusion Female,young(<60 years),chronic pancreati-tis,initial ERCP,hypertension,normal bilirubin levels,difficult cannulation,pancreatic duct guide wire,pa-pillary precut,pancreatography may induce PEP. Female,normal bilirubin levels before operation,initial ER-CP,difficult cannulation and pancreatography are independent risk factors for PEP,while pancreatic duct guide wire,papillary precut are not,as they were linear correlated to difficult cannulation.
ABSTRACT
Objective To evaluate the diagnostic and predict value of procalcitonin (PCT) levels in patients diagnosis of sepsis with immune system defect in the intensive care unit (ICU).Methods This is a retrospective analysis.We enrolled 278 patients diagnosis of sepsis in Emergency ICU,general ICU and Respiratory ICU in Renmin Hospital of Wuhan University from October 2011 to September 2012.Among them,122 patients have normal immune function and 156 patients have auto-immune system diseases or/and requiring corticosteroids or chemotherapy.According to the APACHE Ⅱ score,patients were divided into low-risk group,middle-risk group and high-risk group,and their PCT levels were compared.Logistic regression analysis of the multiple factors was used to screen independent risk factors for predicting 7 days' mortality.The predictive ability was also evaluated and compared between the first time of PCT concentration after admission and dynamic change of PCT within the first week with area under receiver operator's characteristic curve (ROC curve,AUC).Result The results of Spearman correlation analysis showed that there was a significant positive correlation between the patients' PCT concentration and APACHE Ⅱ score (r =0.979,P ＜ 0.05).And there was a positive correlation between the first PCT concentration after admission and 7 days' mortality in-hospital (r =0.826,P ＜ 0.05).Multiple factors logistic regression analysis indicated that both the first time PCT concentration after admission and APACHE Ⅱ score of patients were independent risk factors for predicting 7 days' mortality (PCT OR =1.77,95％ CI =1.28-3.83,P =0.0023).The warning value of 7 days' mortality for patients with normal immune function was PCT≥7.18 ng/ml and for those with abnormal immune function was PCT ≥ 3.52 ng/ml.Compared to dynamic monitoring of PCT,there was no significant difference in sensitivity but specificity is less than the dynamic monitoring of PCT.Conclusions The diagnostic and predict value of procalcitonin (PCT) levels were not affected by the immuno-suppressive therapy.The first time PCT concentration after admission was an independent risk factor for predict of 7 days' mortality in ICU patients with sepsis.The PCT warning value of the sepsis patients with abnormal immune function was much lower compared to those with normal immune function.
ABSTRACT
Phrenic nerve injury after cardiac surgery increases postoperative pulmonary complications. The purpose of this study was to analyze the causes and effects of phrenic nerve injury after cardiac surgery. Prospectively collected data on 2084 consecutive patients who underwent cardiac surgery from Jan. 1995 to Feb. 2002 were analyzed. Twenty-eight preoperative and operation related variables were subjected to logistic analysis with the end point being phrenic nerve injury. Then phrenic nerve injury and 6 perioperative morbidities were included in the analysis as variables to determine their independent predictive value for perioperative pulmonary morbidity. An identical approach was used to identify the independent risk factors for perioperative mortality. There were 53 phrenic nerve injuries (2.5 %). There was no phrenic nerve injury in non-coronary surgery or coronary surgery using conduits other than the internal mammary artery. The independent risk factors for phrenic nerve injury were the use of internal mammary artery (Odds ratio (OR)=14.5) and the presence of chronic obstructive pulmonary disease (OR=2.9). Phrenic nerve injury was an independent risk factor (OR=8.1) for perioperative pulmonary morbidities but not for perioperative mortality. Use of semi-skeletonized internal mammary artery harvesting technique and drawing attention to possible vascular or mechanical causes of phrenic nerve injury may reduce its occurrence. Unilateral phrenic nerve injury, although rarely life-threatening, is an independent risk factor for postoperative respiratory complications. When harvesting internal mammary arteries, it should be kept in mind avoiding stretching, compromising, or inadvertently dissecting phrenic nerve is as important as avoiding damage of internal mammary artery itself.
ABSTRACT
BACKGROUND: The association between the levels of serum lipids and lipoproteins and coronary artery disease(CAD) was well established. This study examines to assess the relation of the concentrations of serum lipids and lipoproteins to the severity of coronary atherosclerosis quantified by angiography. METHODS: We studied 72 patients(men 47, women 25 and mean age 55.6 years) who underwent coronary arteriography for suspected coronary artery disease. Coronary lesion scores were represented by estimates of stenosis in four major coronary vessels. We determined the levels of serum total cholesterol, triglyceride and HDL-cholesterol by biochemical methods. Serum apolipoprotein A-I, apolipoprotein B and lipoprotein(a) were quantified by radioimmunoassay. RESULTS: The distribution of Lp(a)levels among the subject population was highly skewed, with a mean Lp(a) level of 20.0mg/dL and a median of 15.2mg/dL. Coronary lesion scores significantly correlated with Lp(a), HDL-cholesterol levels and the age of patient by univariate statistical analysis. By multivariate analysis, levels of Lp(a) were associated significantly and independently with lesion scores and tend to correlate with the presence of CAD. In men, overall lesion severity of coronary atherosclerosis was related to Lp(a) levels, whereas in women it was related to apolipoprotein B levels by multiple regression anaylsis. CONCLUSION: The serum Lp(a) may be considerably more reliable index of advanced coronary artery disease than other lipids and lipoproteins, especially in men.
