Objective:To understand the status quo of emotional intelligence, emotional labor, and humanistic caring ability of medical staff, and to clarify their internal relationship.Methods:Convenience sampling was used to select 713 medical staff from a grade A tertiary hospital in Chengdu, Sichuan Province, China. Emotional Intelligence Scale, Humanistic Caring Scale, and Emotional Labor Scale were used to measure the emotional intelligence, humanistic caring ability, and emotional labor of medical staff. SPSS 22.0 software was used to establish a database for statistical description and analysis. Process 3.2 software was used to analyze the mediating effect.Results:In humanistic caring ability, the average score of comprehension dimension was the highest (75.62±8.20) and the average score of patience dimension was the lowest (58.53±5.01). In emotional labor, the average score of the deep action dimension was the highest (23.39±3.85) and the average score of the surface action dimension was the lowest (17.73±3.18). In emotional intelligence, the average score of self-emotion evaluation dimension was the highest (21.76±3.30) and the average score of other-emotion evaluation dimension was the lowest (20.07±3.71). Positive correlations were found between humanistic caring ability and emotional intelligence, between humanistic caring ability and emotional labor, and between emotional intelligence and emotional labor ( P<0.01). Humanistic caring ability had a partial mediating effect between emotional intelligence and emotional labor. Humanistic caring ability had direct and indirect effects on emotional labor, and the effect sizes were 0.279 and 0.029, respectively. Conclusion:Emotional intelligence has a direct positive predictive effect on emotional labor, humanistic caring ability as an intermediary variable indirectly and positively predicts emotional labor. Humanistic caring ability plays a partial mediating role between emotional intelligence and emotional labor. Attention should be paid to the emotional labor of medical staff, and the emotional labor of medical staff should be improved through targeted training on emotional intelligence and humanistic caring ability. These efforts will improve the current situation and establish a harmonious doctor-patient relationship.

Objective: To estimate the impact of lymph node dissection on survival in patients with apparent early-stage epithelial ovarian cancer (EOC). Methods: We conducted a retrospective review of patients with clinical stage I–II EOC. All patients underwent primary surgery at Sun Yat-sen University Cancer Center between January 2003 and December 2015. Demographic features and clinicopathological information as well as perioperative adverse events were investigated, and survival analyses were performed. Results: A total of 400 ovarian cancer patients were enrolled, and patients were divided into 2 groups: 81 patients did not undergo lymph node resection (group A), and 319 patients underwent lymph node dissection (group B). In group B, the median number of removed nodes per patient was 25 (21 pelvic and 4 para-aortic nodes). In groups A and B, respectively, the 5-year progression-free survival (PFS) rates were 83.3% and 82.1% (p=0.305), and the 5-year overall survival (OS) rates were 93.1% and 90.9% (p=0.645). The recurrence rate in the retroperitoneal lymph nodes was not associated with lymph node dissection (p=0.121).The median operating time was markedly longer in group B than in group A (220 minutes vs. 155 minutes, p<0.001), and group B had a significantly higher incidence of lymph cysts at discharge (32.9% vs. 0.0%, p<0.001). Conclusion In patients with early-stage ovarian cancer, lymph node dissection was not associated with a gain in OS or PFS and was associated with an increased incidence of perioperative adverse events.

Objective To investigate the association of rs523349(V89L),rs9282858(A49T)and TA repeat polymorphisms in testosterone 5-alpha-reductase Ⅱ(SRD5A2) gene with prostate cancer(PCa) in the population of Yi nationality in Yunnan Province. Methods Sanger sequence detection technique was used to detect rs523349(V89L),rs9282858(A49T)and TA repeat polymorphisms of SRD5A2 gene in 122 subjects with confirmed PCa and 135 age-matched healthy controls in the Yunnan Yi population,then the association of these polymorphisms with prostate cancer was analyzed. Results The AA genotype of rs9282858 site in SRD5A2 gene was not found between the Pca patients and the healthy controls in the Yunnan Yi population. The genotypic and allelic frequency distributions of rs523349 and rs9282858 were not significantly varied between the Pca patients and the controls(P>0.05). But the genotypic and allelic frequency distributions of TA repeat site were significantly varied(P < 0.05). The genotype containing(TA)9 allele was more common in the Pca patients than the healthy controls(P=0.033). Compared with(TA)0 allele subjects,(TA)9 allele subjects had a higher PCa risk(OR=2.181, 95% CI :1.111~4.281,P=0.021). Conclusion The TA repeat polymorphisms of SRD5A2 gene was associated with PCa risk in the Yunnan Yi population,which could be used as a risk factor to screen the high-risk individuals.

Objective To explore the change in 25 hydroxyvitamin D[25 -(OH)D]level in school - aged children with orthostatic hypertension (OHT). Methods Nineteen cases of school - aged children with OHT confirmed diagnosis by head - up tilt table test at the Department of Pediatric Cardiovasology,Children′s Medical Center,the Second Xiangya Hospital,Central South University,from October 2014 to February 2017,were selected as OHT group, including 17 males and 2 females,and their ages were from 7 to 14(11. 21 ± 2. 70)years old. Nineteen healthy children including 17 males and 2 females and aged 8 to 14(11. 05 ± 2. 35)years old who had a healthy examination of child care at the hospital in the same period were selected as healthy control group. In two groups of children all possible basic diseases were eliminated,such as severe liver and kidney disease,abnormal thyroid function and metabolic bone disease and/ or the long - term use of 25 -(OH)D metabolism drugs,accepted the serum 25 -(OH)D detection. Results (1)There was no significant difference in age and gender between the OHT group and the healthy control group(t = 0. 559,P > 0. 05;χ2 = 0. 000,P > 0. 05). The 25 -(OH)D levels were significantly lower in the OHT group than those in the healthy control group [(39. 62 ± 10. 65)nmol/ L vs. (64. 83 ± 10. 28)nmol/ L,t = - 7. 422,P <0. 01]. (2)25 -(OH)D levels had no correlation with age,gender,height,body mass,systolic pressure,or diastolic blood pressure (r = 0. 254,0. 047,0. 195,0. 019,- 0. 191,- 0. 184,all P > 0. 05). Taking 25 -(OH)D level as dependent variable,age,gender,height,body mass,systolic pressure,diastolic blood pressure as independent variables, multiple stepwise regression equation to predict 25 -(OH)D level was not fit. Conclusion Lower level of 25 -(OH)D may be one of the mechanisms for the onset of the school - aged children with OHT.
