Objective To assess the clinical value of conventional contrast enhanced CT(CECT),multi parameter energy spectrum CT,and contrast enhanced MR(CEMR)imaging methods in evaluating hepatocellular carcinoma(HCC)after TACE treatment.Methods The clinical data of 66 HCC patients,who underwent TACE treatment at authors' hospital and received CECT,multi parameter energy spectrum CT and CEMR in 1-3 months after treatment,were retrospectively analyzed.Taking DSA results as the gold standard,the recurrent or residual lesions detected by DSA were classified as positive lesions,while the lesions having no obvious recurrence or residues were classified as negative lesions.The positive lesions that were detected by both DSA and other imaging methods were regarded as true positive lesions.The accuracy,sensitivity,specificity,Kappa value were used to compare the values of CECT,multi parameter energy spectrum CT and CEMR in evaluating the positive/negative lesions of HCC after TACE treatment,and the number of detected lesions and accuracy rate were used to evaluate the values of the above imaging methods in demonstrating the iodine oil deposition status and in diagnosing true positive lesions.Results A total of 133 positive lesions and 35 negative lesions were detected by DSA.The accuracy of CEMR in diagnosing lesions was highest,the accuracy rate was 88.70％(both P＜0.05);CEMR and energy spectrum CT had the highest diagnostic efficiency,the sensitivity for positive lesions was 92.31％and 81.95％respectively,and the difference between the two methods was not statistically significant(P＞0.05).No statistically significant difference in the ability of diagnosing negative lesions existed between each other among the three groups(all P＞0.05).The Kappa value suggested that the ability for diagnosing lesions after TACE treatment of CEMR was stronger than that of energy spectrum CT(Kappa value was 0.68 and 0.56 respectively,both P＜0.05).CECT and multi parameter energy spectrum CT had the same accuracy in evaluating the iodine oil deposition status(both were 91.7％).No statistically significant difference in diagnosing even iodine oil deposition of the true positive lesions existed between each other among the three groups(all P＞0.05).For diagnosing uneven iodine oil deposition of the true positive lesions,CEMR had the highest accuracy(92.50％,all P＜0.05).Conclusion CEMR and multi parameter energy spectrum CT have more reliable diagnostic performance than conventional CECT,besides,CEMR has the highest diagnostic performance.However,multi parameter energy spectrum CT and CECT are the better choice for evaluating the deposition status of iodine oil.

Objective:To investigate the effectiveness of the crisis management theory of reduction, readiness, response and recovery (4R) in the prevention of postoperative complications in patients with lower extremity varices.Methods:Convenience sampling was used to select 172 patients who underwent surgical treatment for lower extremity varices in the Hefei First People's Hospital from October 2022 to November 2023 as study subjects. Patients admitted from October 2022 to June 2023 were recruited in control group ( n=88) with routine nursing. Patients admitted from July to November 2023 were included in observation group ( n=84) , and nursing interventions based on the 4R crisis management theory were implemented on the basis of control group. Postoperative ulcer surface healing time, time for calf numbness to subside, pain scores and postoperative complications were compared between the two groups. Results:The time for disappearance of ulcer surface and the time for calf numbness to subside of the patients in observation group were shorter than those in control group, and the differences were statistically significant ( P<0.05) . Before the intervention, the pain score was (3.58±0.61) in observation group and (3.72±0.57) in control group, and the difference was not statistically significant ( P>0.05) . After the intervention, the pain score was (2.33±0.55) in observation group and (2.50±0.50) in control group, and the difference was statistically significant ( P<0.05) . The incidence of postoperative complications was 4.76% (4/84) in observation group and 19.32% (17/88) in control group, and the difference was statistically significant ( P<0.05) . Conclusions:Nursing interventions based on the 4R crisis management theory can effectively alleviate the pain of patients undergoing lower extremity varicose vein surgery, shorten the time of ulcer healing and calf numbness, and reduce the incidence of postoperative complications.

Objective To explore the effect of lung water management guided by pulse indicator continuous cardiac output (PICCO) in noninvasive-invasive-noninvasive sequential mechanical ventilation to severe acute pancreatitis (SAP) caused acute respiratory distress syndrome (ARDS).Methods The patients with ARDS caused by SAP in the department of critical care medicine in this hospital from January 2012 to January 2015 were selected as the research subjects and divided into the treatment group (lung water management guided by PICCO) and control group(without lung water management guided by PIC CO) according to different lung water management modes.The noninvasive ventilation time,invasive ventilation time,total mechanical ventilation time,mortality rate,incidence rate of pulmonary edema,incidence rate of ventilator associated pneumonia (VAP) and ICU stay time were compared between the two groups.Results The invasive ventilation time in the treatment group was (3.54 ± 1.78)d,which was lower than (4.31 ±2.42)d in the control group(P＜0.05);the occurrence rate of pulmonary edema in the treatment group was 13.64 ％,which was lower than 35.42％ in the control group;the VAP occurrence rate in the treatment group was 6.82 ％,which was lower than 22.92％ in the control group;the mortality rate was 11.36％,which was lower than 29.17％ in the control group;the ICU stay time was (7.21 ± 1.13)d,which was lower than (8.19 ± 1.28)d in the control group,the differences were statistically significant(P＜0.05).Conclusion The lung water management guided by PICCO in SAP caused ARDS sequential mechanical ventilation is more accurate and effective,which is related to accurate liquid management,conduces to the patient's treatment,and is worthy of popularization and application.

BACKGROUNDIncreased proinflammatory cytokines and chemokines might contribute to infiltration of inflammatory cells and remodeling in airways of asthma. Although these molecules may be associated with asthma, there is lack of systemic evidence showing which and how important these events are in the disease. We aimed to analyze the concentrations of these molecules in the airways and relationships with disease severity and with airway infiltration of inflammatory cells in a large cohort of asthmatics (n = 70, including 37 mild and 33 moderate/severe asthmatics) compared with controls (n = 30).

METHODSMeso scale discovery system and commercial ELISA kits were used to measure the concentrations of proinflammatory cytokines interleukin (IL)-1β; tumor necrosis factor-alpha (TNF-α); IL-6; and IL-17 and CC and CXC chemokines CCL2, CCL4, CCL11, CCL13, CCL17, CCL22, and CCL26 and CXCL8, CXCL9, CXCL10, and CXCL11 in bronchoalveolar lavage fluid of asthmatics and controls.

RESULTSThe concentrations of IL-1, TNF-α, IL-6, CXCL8 and CXCL10, and CCL4, CCL11, CCL17, and CCL22 were significantly elevated in asthmatics compared with controls (P < 0.05). The concentrations of TNF-α and CXCL8, but not others, were negatively correlated with severity of disease (lung function forced expiratory volume in 1 s) (TNF-α vs. total: r = -0.359, P= 0.002 vs. moderate/severe: r= -0.541, P= 0.001; CXCL8 vs. total: r = -0.327, P= 0.006 vs. moderate/severe: r = -0.625, P= 0.0001, respectively). In addition, concentrations of these two molecules were also correlated with the absolute numbers of infiltrating eosinophils and neutrophils in asthmatic airways.

CONCLUSIONSIncreased concentrations of TNF-α and CXCL8 are associated with pathogenesis of asthma. Targeting these molecules might provide an alternative therapeutic for this disease.

BACKGROUNDCombined emphysema and pulmonary fibrosis, including idiopathic pulmonary fibrosis (IPF), is a distinct disorder described with upper-lobe emphysema and lower-lobe fibrosis on chest computed tomography. Smoking appears to be the predominant risk factor for this disorder. We aimed to compare clinical features, smoking history, physiological and radiological findings between IPF with and without emphysema.

METHODSA sample of 125 IPF patients over a period of 48 months were evaluated. High resolution CT scans were reviewed blinded to clinical data. The IPF patients with or without emphysema were classified accordingly.

RESULTSThe prevalence of emphysema in this IPF sample was 70/125. IPF with emphysema was significantly associated with smoking status (OR 63; 95% CI 4.4 to 915; P = 0.002) and smoking pack year (OR 1.1; 95% CI 1.05 to 1.13; P = 0.000). The patients with IPF and emphysema had a higher decrease in carbon monoxide diffusing capacity adjusted for alveolar volume ((58±19)% pred vs. (66±21)% pred; P = 0.021) and a higher prevalence of pulmonary hypertension (24/70 vs. 7/55; P = 0.006). The two groups of patients had similar forced and residual volumes. No significant differences were found in cell differentials of bronchoalveolar lavage or the scores of fibrosis on chest CT. Survival of the patients with emphysema was significantly less than that of patients with IPF alone.

CONCLUSIONSCigarette smoking induces IPF combined with emphysema. Emphysema further impairs physiological function and increases the prevalence of pulmonary hypertension that leads to poor prognosis. The inclusion of the patients with combined pulmonary fibrosis and emphysema in IPF clinical trials may lead to under evaluation of the effect of treatment in patients.
