Objective To describe the status quo of hope among nurses in tertiary general hospitals and to explore its influencing factors. Methods A cross-sectional survey was conducted. The Hope Status Scale, the Nurse′s Job Stressor Scale and self-designed demographic questionnaire were delivered to 1 160 nurses from nine hospitals. Results The score of hope scale was 23.05 ± 6.16. Different gender (t=2.045, P=0.004), age (F=7.193, P=0.000), marital status (t=2.806, P=0.005), length of employment (F=11.421, P=0.000), department (F=2.394, P=0.015), monthly income (F=5.351, P=0.001), participate in extracurricular activities (F=37.448, P=0.000) reached a statistically significant level. A significantly negative correlation was found between hope and work stress of nurses (r=-0.233, P=0.000);Logistic regression results showed that participating in extracurricular activities, length of employment, monthly income, departments and job stressors were major influencing factors of hope state of nurses. Conclusions More attention should be paid to the improvement of nurse′s hope. According to the influencing factors of hope, measures should be taken to strengthen the level of hope.

Objective To evaluate the features of cervical lesions on real-time elastography.Methods The elastograms of cervical lesions were analyzed and all of them were evaluated by improved elastographic strain scores,which were classified into 5,and by strain ratio,with pathologic analysis as the reference standard.Results The elasticity scores of all normal cervixes were 1.The score of 95 ％ of benign lesions was not more than 2,the strain ratios of benign lesions were 0.75 ± 0.32.The score of 90％ of the cervical cancer was not less than 3,the strain ratios of 38 malignant lesions were 3.31 ± 1.47.There were significant difference between benign lesions and malignant lesions in elastic scores and elastic strain ratios (P ＜0.001).Conclusions There are some typical features of different cervical lesions on elastography.

Objective To compare the clinical efficacy of different doses of ultrafine extracted granule preparation (EGP) and traditional herbal decoction (THD) of Li Zhong Tang in treatment of epigastric pain. Methods Sixty cases of epigastric pain patients in accordance with the diagnostic criteria of deficiency and cold pattern of spleen and stomach in TCM were randomly divided into THD group, 1/3 dose group and 1/5 dose group, and were given THD, 1/3 dose of ultrafine EGP and 1/5 dose of ultrafine EGP, respectively. The clinical efficacy of the three groups after one course of medication was comparatively analyzed. Results There were no significant differences in age, course of disease, symptom score before treatment, epigastric pain efficacy and syndrome curative effect among the three groups, the differences had no statistical significance (P>0.05). The severity, frequency and duration of epigastric pain were all reduced in the three groups, with significant differences between before and after treatment (P<0.05). Conclusion There are no significant differences in the clinical efficacy on epigastric pain among THD, 1/3 dose of ultrafine EGP and 1/5 dose of ultrafine EGP. In addition, the effect of 1/3 dose group is very close to the THD group.

Objective To explore the application of mini-clinical evaluation exercise (Mini-CEX) in training the diagnostic thinking ability for clinical interns.Methods 83 interns who came to the First People's Hospital of Lianyungang for clinical practice in June 2015 were divided into the experimental group (45 interns) and the control group (38 interns) according to their schools.The two groups received the same clinical teaching according to internship program of five-year clinical medicine,while the experimental group had to take a weekly Mini-CEX training in chnical sections.The diagnostic thinking ability of the two groups was measured by the Diagnostic Thinking Inventory in Chinese version at the beginning and the end of the internship respectively.SPSS 21.0 was applied to processing the data.Measurement data were expressed as mean plus or minus standard deviation,and t test was used in the comparison between groups.Results At the end of the internship,the total score of diagnostic thinking,the score of knowledge structure in memory and the score of flexibility in thinking of the experimental group were higher than scores at the beginning statistically,and the experimental group had a statistically higher score than the control groups in knowledge structure in memory [(69.36 ± 4.28) vs.(66.95 ± 4.78),P=0.018].Conclusion Mini-CEX training can enhance the clinical diagnostic thinking ability of interns by improving their knowledge structure in memory.

Tumor has long been a hard-nut problem in the world medical field. The effect of the conventional drugs is very limited because of the intervention of multiple micro-environmental factors during the occurrence and progression of tumors. With the characteristics of high efficiency, low toxicity and multi-targets synergistic effect, the long-circulating tumor targeted compound preparations show its unique advantages in improving tumor microenvironment and enhancing the therapeutic effect of treatment, thus it has gradually become a hotspot of studies both at home and abroad. Through consulting a great number of professional literatures at home and abroad in recent years, the authors summarized the current studies in vitro and in vive on long-circulating tumor targeted compound preparations in different carriers, in the expectation of providing new ideas and methods for the development of long-circulating tumor targeted compound preparations.

ObjectiveTo investigate the effect of all-trans retinoic acid (atRA) on the renin-angiotensin system (RAS) in 5/6 renal ablation model. MethodsAtRA was administered to 5/6 renal ablation rats by three dosages: 5 mg·kg-1·d-1 (n=8), 10 mg·kg-1d-1 (n=8) and 20 mg·kg-1 d-1 (n=8) and vehicle (vehicle group, n=8) for 10 weeks. Healthy rats consisted of shamoperation group (n =8). The level of renin and angiotensin Ⅱ in renal tissues were measured by radioimmunoassary. The level of angiotensin type 1 receptor (AT1R) in remnant renal cortex was measured by Western blot. The mRNA expression levels of two subunits of activative protein 1(AP-1),c-jun and c-fos was quantitated by real-time PCR. ResultsAfter 10 weeks of atRA treatment by gavarge, artery blood pressure decreased (P＜0.05). AtRA reduced the levels of renin (P＜0.05) and angiotensin Ⅱ (P＜0.05) in kidney and down-regulated the expression of AT1R protein in renal cortex. Larger dose of atRA (20 mg·kg-1·d-1) performed higher activity in inhibiting renin and AT1R. Compared with vehicle group, atRA could significantly inhibit the expression of renal c-jun and c-fos mRNA (P＜0.05). Conclusion atRA can decrease the over-expression of main components of RAS.

Objective To explore the expression and significance of CD44 gastric cancer stem cell biomarker positive circulating tumor cells (CTC ) in peripheral blood of patients with gastric cancer . Methods From March 2010 to December 2012 ,45 patients with gastric cancer and 20 healthy individuals were enrolled .Peripheral blood samples of all the subjects were collected .The expression of CTC and CD44 postive CTC were detected by density gradient centrifugation method and double immunofluorescent staining .Chi‐square test and t‐test were performed for statistical analysis .Results CTC in peripheral blood of healthy controls were not detected .Among 45 patients with gastric cancer ,CTC were detected in 27 patients and 19 of them were CD44‐positive .The difference in positive rate of CTC expression was statistically significant between two groups (χ2 =10 .986 , P<0 .05) .Among 27 CTC‐positive patients , 19 were proximal gastric cancer and 16 of them were CD44‐positive;16 patients had lymph node metastasis and 14 of them were CD44‐positive;13 patients had distant metastasis and 12 of them were CD44‐positive;14 patients had recurrence and 13 of them were CD44‐positive .The CD44 positive CTC was correlated with tumor location ,lymph node metastasis ,distant metastasis and recurrence (χ2=5 .891 ,5 .527 ,5 .787 and 7 .052 ,respectively ,all P<0 .05) .Furthermore ,in 13 patients with recurrence and CD44 positive CTC ,the recurrence time was (10 .54 ± 5 .55) months which was shorter than that of one patients with CD44 negative CTC (19 months) ,and the difference was statistically significant (t= -3 .654 , P=0 .004) .Conclusions CTC which express cancer stem cell marker may be associated with recurrence and metastasis of gastric cancer .It has more important clinical significance to detect this subtype of CTC .
