Objective To explore the relationship between work-family conflict and turnover inten-tions in nurses and find out the key points to reducing turnover intentions by releasing individuals' work-family conflict. Methods Cross-sectional study method was used in this investigation. By using cluster sampling method, 1287 nurses from some top-level and third-class general hospital were investigated. The questionnaire of work-family conflict and turnover intentions scale were used in this research and the re-suits underwent analysis. Results The score of turnover intentions in nurses was positively correlated with the level of their work-family conflict (r=0.233,P<0.01). Stress,behavior and time dimension were related factors of turnover intentions(r=0.243,0.191,0.176,P<0.01 ).After control of demographic factors, the turnover intentions deviation that can be explained increased by 7%. Conclusions The score of work-family conflict is one of the predicators of turnover intentions. A developing measure should be taken to reduce turnover intentions by releasing work-family conflict in nurses.

Objective To explore the correlation between thyroid peroxidase antibody (TPOAb) and outcomes during pregnancy and the effects of treatment on outcomes. Methods PubMed, Cochrane Library, Science Direct, Embase, Chinese Biomedicine, and Wanfangdata had been searched. Case-control and cohort studies about TPOAb and pregnancy outcomes were searched according to the inclusion and exclusion criteria. Fifty studies were finally recruited (all of cohort-studies, 10 for English and 5 for Chinese). Review Manager 5.3 were used to test the heterogeneity of the results among the different studies and amalgamate the effect size using fixed or random effect models. Results Meta-analysis showed TPOAb (+)with normal thyroid function increase the risks of miscarriage,and premature delivery, OR calculated were 2.02(95%CI:1.13-3.62, P=0.001)and 1.39(95%CI:1.11-1.76, P=0.005), while showed no relative risk to hypertensive disease,placental abruption in pregnancy and fetal growth restriction, OR calculated were 1.29(95%CI:1.00-1.67, P=0.080),0.42(95%CI:0.12-1.43, P=0.210)and 1.61(95%CI:0.23-11.12, P=0.100). TPOAb(+)with normal thyroid function increase miscarriage in in vitro fertilization and embryo transfer (IVF-ET), OR calculated were 2.14(95%CI:1.43-3.21, P=0.000). Levothyroxine (LT4) for patients of TPOAb(+)with normal thyroid dysfunction decrease adverse obstetric outcomes, OR calculated were 0.43(95%CI:0.22-0.85, P=0.020). Conclusions TPOAb(+)with normal thyroid function increase the risks of miscarriage,and premature delivery. TPOAb(+) with normal thyroid function increase miscarriage in IVF-ET. LT4 for patients of TPOAb(+)with normal thyroid dysfunction decrease adverse obstetric outcomes.

Objective To research the relationship between the expression of PAI-1 and the clinical characteristics of the endometrial carcinoma.Methods We detected the level of the serum PAI-1 by ELISA in the patients with endometrial carcinoma,the patients with endometrial hyperplasia and the patients with normal endometrium.The expression of PAI-1 in endometrial carcinoma and normal endometrial tissues was observed by immunohistochemistry.Results The concentration of serum PAI-1 in patients with endometrial carcinoma was 18.64 ± 6.22 μtg/L,significantly higher than those of patients with endometrial hyperplasia (6.94 ± 2.87) μg/L and patients with normal endometrium (6.68 ± 2.13)μg/L (P=0.00).The expression rate of PAI-1 was 68.2％ (15/22) in endometrial carcinoma tissue,and 8.3％ (2/24) in normal endometrial tissue (P=0.00).Compared with the early endometrial carcinoma,the expression rate of PAI-1 in the advanced endometrial carcinoma was significantly higher (6/6 w 9/16,P=0.03).Conclusions The expression level of PAI-1 may be related to the stage of the endometrial carcinoma.

Background:Currently,chronic atrophic gastritis( CAG)is diagnosed by endoscopy combined with pathological examination. Narrow-band imaging magnifying endoscopy( NBI-ME)has been widely applied to diagnose CAG. However, it is a issue how to optimize the examination technology. Aims:To investigate the clinical value of NBI-ME in diagnosis of CAG,intestinal metaplasia and intraepithelial neoplasia. Methods:One hundred CAG patients reexamined gastroscopy were enrolled,sequential examination was performd,i. e. the extent of disease was observed under convention white light endoscopy( C-WLI ) followed by NBI-ME mode to observe locally,morphological changes of gastric mucosa pit was analyzed,endoscopic findings and histological results was compared. Results:Sensitivity of sequential examination for the diagnosis of CAG was 89. 7%,specificity was 63. 3%;sensitivity and specificity for the diagnosis of intestinal metaplasia were 89. 4%,89. 3%,respectively,for intraepithelial neoplasia were 84. 2%,95. 9%,respectively.

Objective To evaluate the feasibility and clinical value of identifying sentinel lymph node (SLN) and to assess possible factors associated with detection rate in both cervical cancer and endometrial cancer. Methods Retrospective study of 76 cases (39 with cervical cancer and 37 with endometrial cancer) were conducted in Peking University People′s Hospital. All patients underwent SLN biopsy with tracers of indocyanine green (ICG) and (or) carbon nanoparticles. All mapped SLN was resected and followed by procedures that systematic pelvic lymphadenectomy and hysterectomy according to National Comprehensive Cancer Network (NCCN) guidelines. All the lymph nodes were examined postoperatively for the routine paraffin section of hematoxylin and eosin (HE) staining. Detection rate, sensitivity and negative predictive value of SLN were calculated and factors associated with the detection rate were analyzed. Results The overall detection rate was 95%(72/76), with 74%(56/76) positive bilaterally. The bilateral detection rate of SLN with combined technique was significantly higher than that with single technique (P<0.05). The difference of SLN detection rate between cervical and endometrial cancer patients were not significant (P>0.05). SLN were mostly recognized in obturator (32.1%, 114/355) and external iliac areas (32.4%, 115/355) in cervical cancer, and in external iliac (41.2%, 91/221) and obturator areas (39.4%, 87/221) in endometrial cancer. Among 55 patients underwent systematic pelvic lymphadenectomy, the sensitivity of SLN detection was 75% and the negative predictive value was 96%. The sensitivity and negative predictive value were both 100% in patients with successfully bilateral mapped of SLN. Conclusions The overall detection rate of SLN in cervical and endometrial cancer is the highest with the combined technique of ICG and carbon nanoparticles. The detection rate and located regions of SLN are similar between cervical and endometrial cancer,and SLN are mostly recognized in the external iliac and obturator areas. The sensitivity and negative predictive value of SLN detection are high, especially when SLN are bilateral mapped.

Objective To investigate the clinical value of serum gastric function(pepsinogen I, II and PGR, gastrin-17), Helicobacter pylori (Hp) infection combined with narrow-band imaging magnifying endoscopy for the diagnosis of gastric ulcer. Methods From October 2015 to December 2016, we selected 113 patients diagnosed as gastric ulcer and gastric cancer by narrow-band imaging endoscopy (NBI-ME) and diagnosed by pathological examination. 65 patients were divided into gastric ulcer group. 48 patients were divided into gastric cancer group, 65 healthy subjects who had passed the physical examination were selected as the control group. Enzyme-linked immunosorbent assay was used to measure serum gastric function parameters such as serum pepsinogen I / Ⅱ, PGR, and gastrin-17, and C14 breath test was used to detect Hp. Results The Hp infection rate in the gastric ulcer group and the gastric cancer group was significantly higher than that in the control group, the difference was statistically significant (P＜0. 05). Compared with the control group, serum PG I and PGR levels in the gastric ulcer group were significantly increased (P＜0. 05); serum PG I and PGR levels in the gastric cancer group were lower than those in the control group(P＜0. 05). The PGI and PGR levels in the gastric ulcer group were significantly higher than those in the gastric cancer group, the difference was statistically significant (P＜0. 05). Compared with the control group, the serum G-17 concentration in the gastric ulcer group and the gastric cancer group was higher than that in the control group(P＜0. 05). Conclusion PG I, PG Ⅱ, G-17 and other serum gastric functional parameters combined with Hp indicators have been further measured by NBI-ME in gastric ulcer and gastric cancer diagnosis and prognosis has a high reference value.

Objective: To preliminarily develop the Infectious Disease Prevention Health Literacy Scale for Chinese Middle School Students, as an important measuring tool for assessment of comprehensive abilities in infectious disease prevention of Chinese middle school students. Methods: The basic dimensional framework and item pool were established by literature review in the view of public health. Then Delphi method was used to modify the framework and item pool to scale 1.0. Panel discussion in middle school students was used to adjust the expression and structure of scale 1.0, turning it into scale 2.0. With the confirmation of theory experts subjects, the scale was preliminarily developed. Results: Literature review suggested that the basic dimension framework included five longitudinal dimensions and seven horizontal dimensions.
