Condusions Use of emotional capital management theory was conducive to activate the nursing human resources, improve the quality of the nursing service and the efficiency of management.

Objective To develop an all-in-one multifunctional thoracolumbar fixation rescue vest for land and water rescue of thoracolumbar injury and investigate its application effect.Methods According to the thoracolumbar physiological curve,type Ⅰ thoracolumbar fixation rescue vest with keel and inflatable airbag and type Ⅱ thoracolumbar fixation rescue vest with additional lifesaving balloon and inflatable cylinder were developed using thermoplastic polyurethane (TPU)-nylon composites and polycarbonate (PC) as the main materials.Clinical application of type Ⅰ thoracolumbar fixation rescue vest in 532 cases of thoracolumbar injury was discussed.Type Ⅱ thoracolumbar fixation rescue vest were tested at marine rescue and related parameters measured were automatic inflation time,buoyancy force,floating time,floating condition and victims' face orientation.Clinical outcome was quantified by the MacNab standard,and VAS for pain was recorded.Results According to the MacNab standard,excellent outcome was achieved for all cases.VAS improved from 8.2 points to 2 points after the bracing was applied,showing 100％ improvements.The brace into the water showed automatic inflation time of 3-5 seconds and maximum buoyancy force of 100 kg,and ensured a 90 kg dummy of floating over 96 hours.At marine rescue,the wounded in braced condition showed face upward with 24-hour buoyancy loss ≤5％ and freedom of movement.Conclusions The multifunctional thoracolumbar fixation rescue vest provides dual immobilization and ensures marine rescue for its automatic inflation device.This invention provides the feasibility to remove,transport and evacuate the thoracolumbar fracture patients in cabin.

Objective To explore the predictive factors of sensitivity to preoperative concomitant radiochemotherapy for the local mid-low advanced rectal cancer in order to guide the individualized therapy. Methods Clinicopathologic data of 44 patients with local mid-low advanced rectal cancer receiving preoperational concomitant radiochemotherapy were retrospectively analyzed. Expression of epidemical growth factor receptor (EGFR) in biopsy specimen was detected with SP immunohistochemisty (IHC). Downstaging of tumor TNM stage and tumor regression grade (TRG) after radiochemotherapy were used as the standards of sensitivity to preoperational concomitant radiochemotherapy. Association of EGFR expression and pathological change with clinicopathological data before radiochemotherapy (gender, age, pathological type, tumor TNM stage, serum CEA, CA199, radiation method, etc) was analyzed. Results Percentage of downstaging of tumor TNM stage and 3-4 TRG in patients with negative or weak positive EGFR expression was significantly higher as compared to those with strong and moderate positive EGFR expression [86.7%(13/15) vs. 30.4%(7/23), P<0.01; 80.0%(12/15) vs. 8.7%(2/23), P<0.01]. Percentage of downstaging of tumor TNM stage and 3-4 TRG in patients with tubular adenocarcinoma was significantly higher as compared to those with mucous adenocarcinoma [61.8%(21/34) vs. 10.0%(1/10), P<0.01; 47.1 (16/34) vs. 0 (0/10), P<0.01]. EGFR expression was not associated with pathological type (P>0.05). Sensitivity to preoperative concomitant radiochemotherapy was not associated with age, gender, tumor stage, tumor differentiation, serum CEA, serum CA199 and radiation method (all P>0.05). Conclusions Pathological type and EGFR expression level may be two independent predictive markers of sensitivity to preoperative concomitant radiochemotherapy for patients with rectal cancer. Patients with tubular adenocarcinoma or low EGFR expression in tumor tissue may be more sensitive to concomitant radiochemotherapy.

Objective:To construct the "Internet +" peripherally inserted central catheter (PICC) home nursing service quality evaluation index system, so as to provide objective basis for standardizing the "Internet +" PICC home nursing service quality evaluation.Methods:Based on the three-dimensional quality structure model of "structure-process-outcome", combined with literature research, semi-structured interviews, group discussions and Delphi method, 20 experts who were engaged in intravenous therapy nursing and had management or practical experience in "Internet + nursing services" were selected for two rounds of consultation to determine the "Internet?+" PICC home nursing service quality evaluation index system. The positive coefficient of experts was expressed by the effective response rate of the questionnaire and the rate of expert opinion submission. The degree of expert authority was expressed by the expert authority coefficient. The coordination degree of expert opinions was represented by the Kendall harmony coefficient. The concentration degree of expert opinions was usually expressed in terms of the importance assigned to the indicator, the coefficient of variation, and the full score rate (%) .Results:The effective response rates of the two rounds of consultation questionnaires were all 100%, with expert authority coefficients of 0.793 and 0.848 respectively. The Kendall coordination coefficients of expert opinions were 0.202-0.216 and 0.222-0.270 respectively ( P<0.05). After the second round of expert consultation, the mean importance assigned to all indicators was greater than 4.0, the coefficient of variation was less than 0.2, and the full score rate was greater than 20%. The final "Internet +"PICC home nursing service quality evaluation index system included 3 first-level indicators, 12 second-level indicators and 64 third-level indicators. Conclusions:The "Internet + " PICC home nursing service quality evaluation index system constructed is scientific, reliable and practical, and reflects the specialty characteristics. It can effectively evaluate the "Internet + " PICC home nursing service quality and provide guidance for continuous improvement.

Objective:To explore the relationship between the expression of long chain non coding ribonucleic acid (LncRNA) small nucleolar RNA host gene 1 (LncRNA SNHG1) and microRNA (miR)-143-3p in nasopharyngeal squamous cell carcinoma (HSCC) tissue and clinical pathological features and prognosis.Methods:A prospective selection was made from 97 HSCC patients admitted to the Handan Central Hospital from March 2016 to March 2018. Surgical resection of HSCC tissue and normal mucosa tissue adjacent to cancer were taken, and real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of LncRNA SNHG1 and miR-143-3p. The patient′s survival status was followed up after leaving the hospital. We compared the differences in the expression of LncRNA SNlHG1 and miR-143-3p in HSCC tissues with different clinical pathological parameters, analyzed the correlation between LncRNA SNHG1 and miR-143-3p expression, and the relationship between LncRNA SNHG1 and miR-143-3p expression and the prognosis of HSCC patients.Results:The expression of LncRNA SNHG1 in HSCC tissue was higher than that in normal mucosa tissue adjacent to cancer ( P<0.05), and the expression of miR-143-3p was lower than that in normal mucosa tissue adjacent to cancer ( P<0.05). The expression of LncRNA SNHG1 in cancer tissues of HSCC patients with tumor node metastasis (TNM) stage Ⅲ, low to medium differentiation, and lymph node metastasis was higher than that of HSCC patients with TNM stage Ⅰ-Ⅱ, high differentiation, and no lymph node metastasis (all P<0.05), and the expression of miR-143-3p was lower than that of HSCC patients with TNM stage Ⅰ-Ⅱ, high differentiation, and no lymph node metastasis (all P<0.05). The expression of LncRNA SNHG1 in HSCC tissues is negatively correlated with the expression of miR-143-3p ( r=-0.522, P<0.05). The 5-year cumulative survival rate of HSCC patients with high expression of LncRNA SNHG1 was lower than that of HSCC patients with low expression of LncRNA SNHG1 ( P<0.05), and the 5-year cumulative survival rate of HSCC patients with low expression of miR-143-3p was lower than that of HSCC patients with high expression of miR-143-3p ( P<0.05). Multivariate Cox regression analysis showed that TNM stage Ⅲ and high expression of LncRNA SNHG1 were risk factors for poor prognosis in HSCC patients (all P<0.05), while high expression of miR-143-3p was a protective factor ( P<0.05). Conclusions:The expression of LncRNA SNHG1 is upregulated and miR-143-3p is downregulated in HSCC tissues, with a negative correlation between the two, which is related to the malignant pathological characteristics and poor prognosis of HSCC.
