OBJECTIVE:To investigate the compatible stability of Xiao'aiping injection combined with 3 kinds of common in-jections. METHODS:Referring to package inserts,Xiao'aiping injection 40 mL was compatible with 5% Glucose injection,10%Glucose injection or 0.9% Sodium chloride injection 160 mL,respectively. At room temperature(about 25 ℃)and high tempera-ture(40 ℃),the appearance of mixtures were observed at 0,1,2,4,8,12,24,48 h;pH value and the number of insoluble particles were detected. The contents of tenacissoside A and tenacissoside Ⅰ in mixtures were determined by HPLC. RESULTS:Un-der above condition,the mixtures were brownish yellow liquid within 48 h after Xiao'aiping injection was compatible with 5%Glucose injection or 10% Glucose injection;24 h after mixed with 0.9% Sodium chloride injection,the mixture changed from brownish yellow to reddish brown,but no precipitation was found. The pH value of mixtures had no significant change(RSD<1%,n=8). The number of particles ≥25 μm was in line with the requirements of Chinese Pharmacopeia(2015 edition). For-ty-eight hours after mixing,the number of particles ≥10 μm in the mixtures exceeded the pharmacopoeia limits. Within 48 h after mixing,the relative contents of tenacissoside A and tenacissoside I in mixtures had no significant change(RSD<2%,n=8). CON-CLUSIONS:The mixture should be used up within 24 h after Xiao'aiping injection combined with 5% Glucose injection,10%Glucose injection or 0.9% Sodium chloride injection.

Objective To explore the effect of various information means in the training of newly recruited nurses and to provide a practical basis for comprehensive and thorough development of the training. Methods Nurses who are enrolled in 2015 were chosen as the test group. Its applications can be in the form of Mobile APP,office software,online software and We Chat public platform. Afterwards,the effect of various information means can be judged by comparing the test results with the nurses who are enrolled in 2013 (the control group). The nurses in the test group were surveyed in the form of questionnaires to evaluate the training effect. Results The scores of theory ex amination and nasal feeding in the test group were higher than those of control group(P<0.01). The 93.8 percent of the nurses in test group believe that training is beneficial to the understanding and consolidation of knowledge as well as to improve the ability of self-learning.

Objective To understand the status of vocational maturity of undergraduate nursing students and to discuss the influencing factors. Methods From November 2016 to February 2017, a total of 470 undergraduate in junior grade from School of Nursing of Zhengzhou University were selected as the research objects by convenient sampling method. They were investigated with a general information questionnaire, Career Maturity Inventory (CMI), College Student Adaptability Inventory (CSAI), and the Measuring Scale of Career Self-efficacy. A total of 367 valid questionnaires were collected. Pearson correlation analysis was used to analyze the correlation between career maturity and adaptability, career maturity and self-efficacy of nursing students. Multiple stepwise regression was used to analyze the influencing factors of career maturity of nursing students. Results The total score of occupation maturity of undergraduate nursing students was (107.67±10.35), which was at a middle level. The total score of adaptability and career self-efficacy were positively correlated with the total score of career maturity (r=0.580, 0.140; P< 0.01). Career choice adaptability, overcoming obstacles effectiveness, difficulty perception, self-care adaptability, confidence level and outcome expectation were the influencing factors of career maturity of undergraduate nursing students (P<0.05). Conclusions In nursing education, we should attach importance to students' vocational education, enhance their adaptability and career self-efficacy, so as to improve their career maturity.

Objective To investigate the feasibility of using optimized protocol of iodine contrast agent with fixed injection time in triple-rule-out CT examination of acute chest pain patients. Methods A prospective study was conducted. The patients who underwent triple-rule-out CT examination of acute chest pain at the Second Hospital of Shanxi Medical University from September 2017 to June 2018 were enrolled. According to the patient's body mass index (BMI), they were divided into BMI ≤ 23 kg/m2 group and BMI > 23 kg/m2 group. The patients in each group were subdivided into two subgroups according to the random number table, and they were given two iodine contrast injection protocols with fixed injection time (14 s). Protocol 1 was performed with 55 mL of total iodinated contrast media: iodinated contrast media was first injected at 5.0 mL/s for 8 s, followed by the same contrast media injection at 2.5 mL/s for 6 s, finally followed by injection of 40 mL of saline at a rate of 2.5 mL/s. Protocol 2 with 60 mL of total iodinated contrast media: iodinated contrast media was first injected at 5.0 mL/s for 10 s, followed by the same contrast media injection at 2.5 mL/s for 4 s, finally followed by injection of 40 mL of saline at a rate of 2.5 mL/s. The primary and objective evaluation was conducted on the image quality of the patients' blood vessels in different segments. The primary score, CT value and contrast-to-noise ratio (CNR) of the pulmonary artery, coronary artery, aorta and total effective radiation dose for the examination were recorded. Results A total of 92 patients were enrolled in the analysis. There were 44 patients in BMI≤ 23 kg/m2 group, in which 22 patients received in protocol 1 and protocol 2, 48 patients in BMI > 23 kg/m2 group, in which 24 patients in protocol 1 and protocol 2, respectively. There was no significant difference in the effective radiation dose between the two subgroups receiving different injection protocols in different BMI groups (mSv: 6.7±1.1 vs. 6.5±0.8 between protocol 1 and protocol 2 in BMI ≤ 23 kg/m2 group; 7.8±1.0 vs. 8.0±1.1 between protocol 1 and protocol 2 in BMI > 23 kg/m2 group, both P > 0.05). In BMI ≤ 23 kg/m2 group, the CT value, CNR and primary scores of pulmonary artery images in patients receiving protocol 2 were significantly higher than those receiving protocol 1 [CT value (HU): 584±110 vs. 472±86 for main pulmonary artery, 561±93 vs. 467±78 for left pulmonary artery, 555±91 vs. 472±83 for right pulmonary artery; CNR: 24.2±7.5 vs. 18.7±4.6 for main pulmonary artery, 23.2±6.8 vs. 18.6±4.8 for left pulmonary artery, 22.9±6.7 vs. 18.8±4.7 for right pulmonary artery; primary score:4.0 (4.0, 4.0) vs. 3.5 (3.0, 4.0), all P < 0.05]; and there was no statistically significant difference in the primary or objective evaluation of coronary artery or aortic image quality between the two protocols. In BMI > 23 kg/m2 group, the CT value, CNR and primary scores of coronary artery and aortic images in patients receiving protocol 2 were significantly higher than those receiving protocol 1 [CT value (HU): 369±63 vs. 315±61 for proximal right coronary artery (RCA), 388±63 vs. 323±63 for proximal left coronary artery (LCA), 328±83 vs. 272±51 for ascending aorta, 348±82 vs. 272±49 for aortic arch; CNR: 15.0±4.6 vs. 12.3±4.7 for proximal RCA, 15.7±3.8 vs. 12.8±5.2 for proximal LCA, 13.2±5.3 vs. 10.4±4.1 for ascending aorta, 14.1±5.3 vs. 10.4±3.9 for aortic arch; primary score: 4.0 (3.0, 4.0) vs. 3.0 (3.0, 4.0) for coronary, 4.0 (3.0, 4.0) vs. 3.0 (2.0, 4.0) for aorta; all P < 0.05]; and there was no statistically significant difference in the primary or objective evaluation of pulmonary artery image quality between the two protocols. Conclusions The effective radiation dose of triple-rule-out CT examination of acute chest pain is relatively low. The low-dose iodine contrast agent application program with fixed injection time can meet the needs of clinical diagnosis of triple-rule-out CT examination of acute chest pain patients. For patients with BMI ≤ 23 kg/m2, both protocols 1 and 2 can obtain excellent image quality; in order to avoid the influence of superior vena cava artifacts, protocol 1 is recommended. For patients with BMI > 23 kg/m2, application protocol 2 can obtain stable, excellent image quality that is more suitable for clinical applications.

OBJECTIVETo observe the dynamic changes of pulmonary function and inhaled corticosteroid (ICS) doses during subcutaneous immunotherapy (SCIT) with standardized house dust mite vaccine (Alutard) in children with mild to moderate allergic asthma.

METHODSOne hundred children with mild to moderate allergic asthma were randomized into SCIT group and control group for treatment with SCIT plus ICS and with ICS only, respectively. The pulmonary function and ICS doses were evaluated before and every 3 months during the 2 years of treatment.

RESULTSNo significant difference was found in the pulmonary functions between the two groups before the treatment (P>0.05). After 3 months of treatment, FEV1% and PEF% in SCIT group were significantly higher than those in the control group [(103.19∓2.07)% vs (97.52∓1.92)%, and (105.56∓3.21)% vs (96.35∓2.7)%, respectively]; at 21 months, FEF50% and FEF25% were significantly higher in SCIT group than in the control group [(105.69∓3.29)% vs (94.61∓3.12)%, and (106.60∓3.71)% vs (92.92∓3.31)%, respectively]. A significant difference was found in ICS doses between SCIT group and the control group after 9 months of treatment (147.14∓6.41 vs 170∓4.95 µg/day, P<0.05), and the difference increased as the treatment prolonged.

CONCLUSIONSCIT combined with ICS can improve the ventilation function of the large airways early after the commencement of treatment, but its effect on small airways can be delayed. SCIT for 2 years shows a good therapeutic effect and can reduce the doses of ICS in children with mild to moderate allergic asthma.

OBJECTIVETo identify the differentially expressed microRNAs (miRNAs) between esophageal squamous carcinoma (ESC) and adjacent non-tumorous tissue (NT).

METHODSThe expression levels of the miRNAs were detected in 3 fresh ESC and NT samples by hybridization with miRNAs microarray chip. Real-time quantitative RT-PCR was performed to confirm the results of the microarray analysis. The expressions of hsa-miR-126 and hsa-miR-518b in ESC were validated by real-time quantitative RT-PCR in another independent 15 matched samples.

RESULTSA total of 11 miRNAs exhibited differential expressions in ESC samples as compared to their expressions in the NT samples, including a 1 up-regulated miRNA and 10 down-regulated miRNAs. Compared with normal esophageal samples, the ESC tissues showed up-regulated hsa-miR-126 and down-regulated hsa-miR-518b expression.

CONCLUSIONhsa-miR-126 and hsa-miR-518b are differentially expressed in ESC, and they might play important roles in the carcinogenesis and progression of ESC.
