Objective To systematically evaluate the comprehensive effect of subglottic secretion drainage (SSD) on patients with mechanical ventilation (MV) in intensive care unit (ICU). Methods The randomized controlled clinical trials (RCTs) comparing SSD (intervention group) versus non-SSD (control group) in adult patients with MV in ICU was collected through the databases such as the PubMed database of the National Library of Medicine, CNKI, Wanfang database and the Chinese journal of science and technology database (VIP). The subjects were ICU patients with MV, and the retrieval time ranged from January 2006 to December 2016. Two reviewers independently screened the studies according to the inclusive and exclusive criteria, extracted the data, and assessed the quality. Then RevMan 5.3 software was used for Meta-analysis. Sensitivity analysis was performed using Stata 11.0 software. Funnel plot was used to analyze publication bias. Results In the 1004 documents obtained from preliminary screening, a total of 13 studies involving 2052 patients were enrolled after excluding duplicated documents and literature did not meet the inclusion criteria, with 1021 patients in intervention group, and 1031 in control group. Meta-analysis showed that compared with control group, the application of SSD in patients with MV could contribute to the reduction of the incidence of ventilator-associated pneumonia [VAP; risk ratio (RR) = 0.54, 95% confidence interval (95% CI) = 0.46-0.64, P < 0.00001], the duration of MV [mean difference (MD) = -3.29, 95%CI = -4.53 to -2.05, P < 0.00001] and length of hospital stay (MD = -4.27, 95% CI = -7.36 to -1.18, P = 0.007) were shortened, while there was no significant difference in ICU or hospital mortality rate between the intervention group and control group (RR = 0.89, 95%CI = 0.73-1.09, P = 0.25). The sensitivity analysis for studies enrolled in Meta-analysis of MV duration showed that individual research results were stable through step remove of the included literatures and combined calculation of the remaining literature value, suggesting that individual research results were stable, and would not have a significant impact on the overall results. The results of the funnel analysis showed that there was a symmetry in the inclusion studies, and no significant publication bias was found. Conclusions SSD did have effect in reducing the incidence of VAP, shortening the duration of MV and length of hospital stay, while there was no significant effect on reducing mortality rate. Effective use of SSD is an important measure to prevent VAP. It is necessary to objectively evaluate the clinical effect of SSD.

Objective To describe a new kind of Y-shaped metallic stent delivery system and evaluate its feasibility and preliminary effect for managing multiple airway stenoses involving the lower trachea and the tracheal carina.Methods The Y-shaped metallic stent delivery system consisted of three- tier structure.The inner-tier was composed of four parallel guiding tubes,which was used for two guidewires and two threads passing through,the middle-tier was delivery catheter,which contained the four guiding tubes,and the outer-tier was introducer sheath.Under the fluoroscopic guidance,15 patients with multiple stenoses involving the lower trachea and the tracheal carina were treated with the new covered self-expandable Y-shaped metallic stents.Results Stent placement in the tracheo-bronchial tree was technically successful in all patients with obliteration of the dyspnea immediately after stent placement,and SaO_2 was increased form preoperative 75%—89% to postoperative 96%—99%.During follow-up a period of 3—58 weeks (M 22 weeks),all stenosis were resolved without stent-related complications,and the general physical of all 15 patents was improved with no occurrence of obviously dyspnea and bleeding.Karnofsky performance status(KPS)was improved from preoperative 26%—45% to postoperative 72%—95%.Five patients died of the following causes unrelated to stent insertion:multiple organ failure(n=3),cachexia(n=1)and pulmonary infection caused by gastrobronchial fistula(n=1),and the remaining 10 patients were alive with no evidence.of dyspnea at the time of this report.Conclusion Deployment of the covered Y-shaped metallic stent with the use of Y metallic stent delivery system in the management of airway stenoses involving the lower trachea and the tracheal earina was a simple and safe procedure and with a good short-term clinical efficacy.

Objective To analyze the relationship between the catheter to vein ratio and the formation of peripheral insertion of central venous catheter (PICC) related upper extremity deep venous thrombosis (PICC-UEDVT) in cases having undergone PICC in patients at intensive care unit (ICU) and further identify the best optimal ratio cut-off point to reduce the incidence of PICC-UEDVT.Methods A retrospective study was conducted, including 69 patients having undergone PICC with complete clinical data admitted to the Department of Critical Care Medicine of the First Affiliated Hospital of Nanchang University from August 2013 to December 2016; their ages were > 18 years old and catheter indwelling times were > 1 week; the patients' basic information, disease related laboratory parameters and catheter insertion situation were collected. According to the occurrence of PICC-UEDVT, they were divided into PICC-UEDVT group and non PICC-UEDVT group; the receiver operating characteristic (ROC) curve of the catheter to vein ratio versus the incidence ofPICC-UEDVT was plotted to assess the optimal ratio to reduce the incidence of PICC-UEDVT.Results In the 69 patients, there were 7 patients in the PICC-UEDVT group and 62 patients in the non PICC-UEDVT group, the incidence of PICC-UEDVT being 10.14%. Four, 5 and 6 French (Fr) catheters were indwelled in 43, 23 and 3 cases respectively, and the range of catheter to vein ratio was 20% - 67%. The comparisons between PICC-UEDVT group and non PICC-UEDVT group in various aspects were as follows: the incidence of DVT in the PICC-UEDVT group was significantly higher than that in non PICC-UEDVT group [42.9% (3/7) vs. 6.5% (4/62)], the rate of using vasopressor drugs [57.14% (4/7) vs. 17.74% (11/62)], D-dimer level [mg/L: 9.0 (3.0, 12.3) vs. 1.8 (1.0, 3.6)], patients of indwelling 5Fr catheter [71.4% (5/7) vs. 29.0% (18/62)] and the percentage of patientsapplying catheter to vein ratio 45%-67% [57.14% (4/7) vs. 17.74% (11/62)] in PICC-UEDVT group were all higher than those in the non PICC-UEDVT group, the differences being statistically significant (allP < 0.05). ROC analysis showed that the catheter to vein ratio 44% was the optimal cut off or critical point, the area under the ROC curve (AUC) at that point was 0.755, 95% confidence interval (95%CI) = 0.554-0.955, sensitivity = 71.4% and specificity = 79.0%; compared with the patients using 45%-67% catheter to vein ratio, the incidence of PICC-UEDVT was 6.182 times higher than those using the ratio 20%-44% [odds ratio (OR) = 6.182, 95%CI = 1.208-31.634,P = 0.036]; however, there was no significant difference in incidence of PICC-UEDVT between 20%-32% and 33%-44% (P = 1.000).Conclusion It is found that the 44% catheter to vein ratio was the optimal critical point to reduce the incidence of PICC-UEDVT, possessing relatively high sensitivity and specificity; applying <44% catheter to vein ratio can decrease the risk of PICC-UEDVT occurrence in patients at ICU.

Objective To study the effect of nursing intervention on the depression patients and their members. Methods 116 depression patients were randomly divided into two groups, the study group ( n = 59) and the control group (n = 57 ). 59 family members of the study group were selected. Patients of the two groups all accepted the routine therapy and nursing intervention. At the same time, the family members of the study group accepted the family nursing intervention once a week, and the intervention continued for 8 weeks. The curative effects of patients were evaluated by HAMD ( Hamilton Depression Rating Scale) and SDS, and the psychological state of family members were examined by SCL-90 (Symptom Checklist 90). Results Through 8 weeks of nursing intervention, scores of HAMD and SDS of the study group were (13.74±6.34)and (3.82±1.24), respectively, showing a statistical meaning compared to the control group (P <0.05). The scores of somatization, depression and anxiety in SCL-90 were significantly improved in the family members of depression patients in the study group. Conclusions Implementing nursing intervention among the depression patients and their family members can improve the curative effect, facilitate the rehabilitation, and ameliorate the psychological health of family members.

Objective To explore the relationship of subjective well-being (SWB), social support and coping styles among burn patients. Methods 150 burn patients were investigated with subjective well-being index scale, social support rating scale and medical coping modes questionnaire (MICMQ). Results Average scores of total well-being index, total emotional index and total life satisfaction were (26.96 ± 13.91), (24.03 ±12.51)and (2.93 ± 1.63), respectively. There were statistically significant correlations among dimensions of social support, positive coping style and subjective well-being. Conclusions Total social support and positive coping style are the influencing factors of SWB of burn patients.

OBJECTIVETo investigate the expression profiles of serum Golgi protein-73 (GP73) in liver cirrhosis and primary hepatic carcinoma (PHC) and determine its clinical value for differential diagnosis.

METHODSSerum protein expressions of GP73 and alpha-fetoprotein (AFP) were detected by enzyme-linked immunosorbent assay and chemiluminescence assay, respectively, in patients with PHC (n=80), liver cirrhosis (n=65), and healthy controls (n=50). Inter-group changes were assessed by Kruskal-Wallis test, and significance of these differences was assessed by Mann-Whitney test. A receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficiency and determine the cut-off values for GP73 and AFP. Sensitivity and specificity were compared by the Chi-squared test. Correlation between serum GP73 expression and clinical parameters was determined by Spearman's rank correlation analysis.

RESULTSThe PHC group showed significantly higher serum GP73 (282.0 mug/L) than the liver cirrhosis group (211.8 mug/L) and control group (58.3 mug/L) (H = 93.30, P less than 0.01). For differential diagnosis of PHC and liver cirrhosis, the cut-off value was 318.1 mug/L for GP73 and 13.4 mug/L for AFP. Sensitivity of GP73 was lower than AFP (45% (36/80) vs. 65% (52/80); X2 = 8.02, P less than 0.05). Specificity of GP73 was lower than AFP but no significance was found (83.1% (54/65) vs. 87.7% (57/65); X2=0.27, P more than 0.05). The areas under the ROC curves were not significantly different between GP73 and AFP (0.65 (95% confidence interval (CI): 0.54~0.72) vs. 0.75 (95% CI: 0.67~0.83); Z = 1.88, P more than 0.05). The area under the ROC curves increased but not significantly (0.80 (95% CI: 0.73~0.88) vs. 0.75 (95% CI: 0.67~0.83); Z=2.61, P more than 0.05). Serum GP73 was correlated with liver cirrhosis (r=0.27), vascular invasion (r=0.29), and TNM staging (r=0.27) (all P less than 0.05), but not with sex (r=0.13), age (r=0.10), enhanced AFP (> 13.4 mug/L; r=0.03), tumor size (r=0.18), or distant metastasis (r=0.04), all P less than 0.05.

CONCLUSIONSerum GP73 and AFP have comparable diagnostic efficiency, but the sensitivity of AFP is superior for differential diagnosis of liver cirrhosis and primary hepatic carcinoma. Elevated serum GP73 may be correlated with liver tumor load and aggressiveness.
