Objective To evaluate left ventricular function in patients with acute myocardial infarction(AMI)by autologous peripheral blood stem cells(PBSCs)transplantation with echocardiography.Methods Patients with AMI were randomly assigned to receive intracoronary PBSCs transplantation following bone marrow cells mobilization(standard drug therapy and PCI,PBSCs transplantation group,n=35)or only receive standard therapy(standard drug therapy and PCI,n=34).Echocardiography were performed before and 6 months after treatment.Results LV function was significantly improved 6 months after G-CSF mobilized autologous PBSCs transplantation compared to baseline(P

Objective To evaluate the effect of traditional Chinese medicine sputum discharge liquid on preventing ventilator-associated pneumonia(VAP).Methods A randomized double-blind,placebo-controlled study was con-ducted,according to the inclusion and exclusion criteria,patients with respiratory failure and mechanical ventilation in the intensive care unit (ICU)of a hospital in 2011 -2014 were selected and divided into treatment group and con-trol group.Treatment group received sputum discharge liquid in addition to conventional treatment,control group adopted simulation agent based on conventional treatment.The incidence,treatment effectiveness,occurrence time, and prognosis of VAP between two groups of patients were compared.Results A total of 139 patients were monitored,70 cases in treatment group and 69 in control group.The incidence of VAP in treatment group and con-trol group were 37.14% (n =26)and 57.97%(n =40)respectively;the average onset time of VAP in treatment group and control group were (76±3.2)hours and (45±8.9)hours after admission to ICU respectively;treatment effectiveness rates in treatment and control group were 88.46% and 55.00% respectively;the incidence,occurrence time,and treatment effectiveness rates of VAP between two groups of patients were both significantly different (all P <0.05).There were no significant difference in blood routine,liver and kidney function,urine routine,stool rou-tine,and electrocardiogram results between two groups of patients (all P >0.05 ).Conclusion Intervention in patients with mechanical ventilation by sputum discharge liquid can reduce the incidence of VAP,and has a positive effect on the prognosis of disease and pulmonary infection in patients.

Objective To investigate the protective function of edaravone in the compressed spinal cord.Methods There were 150 rabbits enrolled in each group in the experiment.Rabbits in both operation group and edaravone (EDA) treating group received mild spinal cord compressionby setting a flap head screw between C6 C7 after the neck.The spinal cord decompression was conducted seven days later.After 6 hours,rabbits in the EDA treating group were injected with a large amount of EDA through ear border veins,while the rabbits in the operation group only received 0.9％ sodium chloride injection.The transmission electron microscope was used to observe the apoptotic bodies at 1 day,3 days and 7 days after compression,and 1 day,3 days,7 days,and 14 days after decompression.Flow cytometry was used to test the rate of apoptosis of spinal cord cells.Immunohistochemistry was used to test the expression of Bax protein that is related to apoptosis.Results The neuronal apoptosis appeared after compression in both operation group and EDA-treating group.The Basso Beattie Bresnahan (BBB) score,neuronal apoptosis rates,and Bax protein expressions in both groups were statistically different (P ＜ 0.05) when the spinal cord was compressed in the first day and the third day,while there was no statistically different when spinal cord compressed at the seventh day (P ＞ 0.05).After decompression of the spinal cord,the BBB score,neuronal apoptosis rates,and Bax protein expressions in both groups were becoming lower at the seventh day (P ＜0.05).Conclusions EDA has protective function for compressed spinal cord.However,only the compression of spinal cord compression period of sufficient decompression can fundamentally protect the spinal cord.

The umbilical vein catheterization is one of the most common interventions in neonates.Central line-associated bloodstream infections is a frequent complication of umbilical vein catheterization.It may lead to increased morbidity and mortality by 7% to 11%.At present, published literature on umbilical vein catheter-related bloodstream infections is limited in China.Our better knowledge of its epidemiology, risk factors and preventive measures could help to improve clinical practice and guide future research.

Objective To observe the value of speckle-tracking imaging (STI) in evaluation on degree of coronary artery stenosis in patients with coronary artery disease (CAD).Methods Totally 74 CAD patients,including 59 with coronary artery stenosis (coronary artery stenosis group) and 15 without coronary artery stenosis (no coronary artery stenosis group) underwent STI and echocardiography.Based on Gensini scores,the patients in coronary artery stenosis group were further divided into mild,moderate and severe subgroups.The average global longitudinal strain (GLS-Avg),basement global longitudinal strain (GLS-Bas),middle global longitudinal strain (GLS-Mid) and apical global longitudinal strain (GLS-AP) value were measured and compared.Results GLS-Avg,GLS-Bas,GLS-Mid and GLS-AP value in coronary artery stenosis group were lower than those in no coronary artery stenosis group (all P ＜ 0.001).In coronary artery stenosis group,with the increase of stenosis severity,GLS-Avg,GLS-Bas,GLS-Mid and GLS-AP value decreased,and statistical differences were found between each two subgroups (all P＜0.05).In coronary artery stenosis group,there were positive correlations between GLS-Avg,GLS-Bas,GLS-Mid,GLS-AP value and Gensini scores (r=0.861,0.847,0.819 and 0.778,all P＜ 0.05).Conclusion GLS value of STI can reflect the severity of coronary artery stenosis in CAD patients.

Objective To investigate the value of endoscopic ultrasonography(EUS)in the diagnosis and treatment of undetermined etiology of common bile duct (CBD) dilatation. Methods Patients, who were referred for dilated CBD but unable to identify the cause by imaging, underwent EUS for the diagnosis of etiology in Endoscopy Center of Zhongshan Hospital Affiliated to Fudan University from December 2015 to December 2016. The therapy was on the basis of diagnosis of EUS. Final diagnoses were determined by surgical pathology or follow-up for at least 3 months. Results A total of 76 patients were included in the study. The sensitivity, specificity and accuracy of EUS for patients with choledocholithiasis,patients with ampullary tumor, and patients with inflammatory stenosis were 100.0%(7/7), 100.0%(69/69), 100.0%(76/76), and 88.0%(22/25), 92.2%(47/51), 90.8%(69/76),and 90.9%(40/44), 93.8%(29/32), 90.8%(69/76), respectively. Accuracy of EUS for etiological diagnosis of CBD dilatation was 90.8%(69/76). The sensitivity,specificity and accuracy of EUS combined with tumor markers for patients with malignant CBD dilatation were 96.0%(24/25), 96.1%(49/51),and 96.1%(73/76), respectively. Conclusion EUS is an effective method for the etiological diagnosis of CBD dilatation and has guiding significance for the treatment. EUS combined with tumor markers may benefit differential diagnosis of benign and malignant CBD dilatation.

OBJECTIVE: To investigate the correlation of procalcitonin (PCT), interleukin-6 (IL-6) and antithrombin III (AT III) with the severity of sepsis, and to compare the predictive value of the above indicators alone or in combination. METHODS: A retrospective cohort study was conducted. Eighty-five patients with sepsis admitted to the department of intensive care medicine of Shandong Provincial Hospital Affiliated to Shandong First Medical University from April 2021 to September 2022 were enrolled. General information, sequential organ failure assessment (SOFA) score and acute physiology and chronic health evaluation II (APACHE II) score within 24 hours of admission, inflammatory indicators [PCT, IL-6, serum amyloid A (SAA), neutrophil to lymphocyte ratio (NLR), and C-reactive protein (CRP)] and coagulation indicators (D-dimer and AT III) levels at admission, and 28-day prognosis were collected. The differences of the above indicators were compared among patients with different prognosis at 28 days and different severity of sepsis. The correlation between PCT, IL-6, AT III and the severity of sepsis was analyzed by Spearman rank correlation method. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of PCT, IL-6 and AT III alone or in combination on the 28-day death of patients with sepsis. RESULTS: Eighty-five patients were enrolled finally, 67 cases survived and 18 cases died at 28 days. The mortality was 21.2%. There were no statistical significant differences in gender, age and other general data between the two groups. The patients in the death group were more serious than those in the survival group, and PCT, IL-6, and CRP levels were significantly higher than those in the survival group [PCT (μg/L): 4.34 (1.99, 14.42) vs. 1.17 (0.31, 3.94), IL-6 (ng/L): 332.40 (50.08, 590.18) vs. 61.95 (31.64, 194.20), CRP (mg/L): 149.28 (75.34, 218.60) vs. 83.23 (48.22, 174.96), all P < 0.05], and AT III activity was significantly lower than that in the survival group [(53.67±28.57)% vs. (80.96±24.18)%, P < 0.01]. However, there were no significant differences in D-dimer, NLR and SAA between the two groups. Among the 85 patients, 36 had sepsis with single organ dysfunction, 29 had sepsis with multiple organ dysfunction, and 20 had septic shock with multiple organ dysfunction. With the increase of the severity of sepsis, PCT and IL-6 levels gradually increased [PCT (μg/L): 0.36 (0.19, 1.10), 3.00 (1.22, 9.94), 4.34 (2.18, 8.86); IL-6 (ng/L): 43.99 (20.73, 111.13), 100.00 (45.37, 273.00), 332.40 (124.4, 693.65)], and the activity of AT III decreased gradually [(89.81±21.42)%, (71.97±24.88)%, and (53.50±25.41)%], all with statistically significant differences (all P < 0.01). Spearman rank correlation analysis showed that PCT and IL-6 levels in sepsis patients were significantly positively correlated with the severity of the disease (r values were 0.562 and 0.517, respectively, both P < 0.01), and AT III activity was significantly negatively correlated with the severity of the disease (r = -0.523, P < 0.01). ROC curve analysis showed that PCT, IL-6, and AT III alone or in combination had some predictive value for the death of sepsis patients at 28 days. The area under the ROC curve (AUC) of the above three indicators in combination was higher than that of the individual tests (0.818 vs. 0.722, 0.725, and 0.770), with a sensitivity of 83.3% and a specificity of 73.1%. CONCLUSIONS PCT, IL-6, and AT III were significantly correlated with the severity of sepsis patients. The combined assay of the above three indicators can effectively improve the prediction of the prognosis of sepsis patients.
