Using floating microelectrode, the effects of furosemide on action potential and contractile force were studied in isolated toad atrial myocardium. Furosemide increased the force of contraction of toad right atrial myocardium, amplitude and dV/dtmax of action potential, and prolonged action potential duration at 50% repolari-zation (APD50), but the APD25, APD90 and sinus cycle length ( SCL) were not influenced. The positive intropic effect of furosemide could be blocked by Verapamil. These results indicated that furosemide could promote the Ca++ inward current.

Objective　To investigate the effect of turning scleral flap of self-body over drainage in trabeculectomy.Methods　The surgery was performed on one eye of a rabbit while　the other eye of the same rabbit was conducted with the routine trabeculectomy as the control group. The filtering bleb, intraocular pressure and pathology were observed. Results　The intraocular pressure in the experimental eye was much lower than that in the control group 3～12 weeks after the operations (P＜0.05).As it was within 2 weeks after the surgeries, but there was no significant filtering difference (P＞0.05).The rate of eyes with functional bleb in the experimental group was significantly higher than that in the control group at the postoperative 2～7 weeks .Conclusion　This study suggests the turning of self-body over drainage surgery can help to maintain filtering function for a long time and to prevent complication after filtering surgery.

To investigate the expression of Toll-like receptor (TLR) 2 and 4 mRNA in local tissues of model of oropharyngeal candidiasis in mice and to explore the potential role of TLR2 and TLR4 in earlier period of immune response, a murine model of oropharyngeal candidiasis inoculated by cotton wool balls saturated with Candida albicans was established. Mice were sacrificed at the indicated time points and the oropharyngeal tissues were excised. The expression of TLR2 and TLR4 mRNA was detected by RT-PCR. The results showed that low level of TLR2/4 mRNA could be detected in oropharyngeal tissues, but they were markedly up-regulated 6 h after inoculation, peaking after 12-24 h. Tissue TLR4 mRNA was gradually down-regulated 24-48 h, while TLR2 mRNA levels remained high up to the 72nd h. These data suggested that oropharyngeal infection of Candida albicans could result in up-regulation of TLR2/4 mRNA expression in local tissues, which might play important roles in earlier period of immune response.

Objective To find out the present situation and influence factor in core capabilities of nurses that with blood purification skills in 18 hospitals, and offer reference frame for training. Methods The questionnaires were used to investigate, theresults underwent analysis. Results Among three parts of core capabilities, total score of N1-2 made the highest,the mean score was 236.75,N3 score made the lowest,the mean score was 168.00. The percent of pass in every hierarchy didn't passed 50%. Using the multiple regression to analyze the factor,N1-1 was the work experience in department of nephrology;N3 was the training time of blood purification. Conclusions Percent of pass in core capabilities of nurses of blood purification is in a low level,every hospital should follow the principle of recruitment,and regulate the training of nurses in blood purification.

Objective To find out the present situation and influence factor in core capabilities of nurses of blood purification, and offer reference frame for evaluation, selection, authentication and engagement of nursing post. Methods Core capability training module for nurses of blood purification was selected as theoretical basis for rough draft of evaluation index system establishment. The selected index underwent expert consultation with Delphi method. Results Four hierarchy were confirmed after 3 rounds of consultation (N1-1,N 1-2, N2, N3). Each hierarchy had three evaluation indexes, knowledge, technology and clinical practice. Number of grade one evaluation indexes of each hierarchy was 5,5,4; 5,5, 4;5,5,5; 5,5,1. Number of grade two evaluation indexes was 20,20,24;20,20,20;25,25,48;23,24,14.Only N1- 1,N1-2 and N2 had grade three evaluation indexes, 16, 5, 13 respectively. Conclusions Preliminary establishment of core capability evaluation index system can basically evaluate capability of nurses of blood purification.

ObjectiveTo analyze the status of DACH1 gene promoter methylation and explore its association with the expression of DACH1 gene promoter methylation and clinical significance of endometrium carcinoma(EC).Methods From February 2004 to August 2008,a total of 80 EC tissue samples with comprehensive surgical pathology staging were collected and used for this study.Twenty normal endometrium tissues in 2008 were abtained from the fractional curettage because of dysfunctional uterine bleeding as control.All samples were confirmed pathologically.Methylation specific PCR (MSP) was performed to detect the promoter methylation of DACH1 gene,and analyze its influence on the expression of DACH1 and the relationship between DACH1 promoter methylation and clinicopathological factors in EC.DACH1 protein expression was detected by western blot.Chi-square test and Pearson test were used for statistical analysis.ResultsThe rate of promoter methylation of DACH1 gene in the EC tissues was significantly higher than that in the normal endometrium issues (30％ vs.5％,P ＜ 0.05).There was an association between the expression of DACH1 and DACH1 gene promoter methylation ( r =- 0.30,P ＜ 0.01 ).There was statistical difference between the methylation of DACH1 and the pathological grade ( P ＜ 0.05 ) or histological type ( P ＜0.05).But DACH1 gene methylation was not related with the age,stage,myometrial invasion depth and lymphnode metastasis (P ＞ 0.05 ).Conclusions DACH1gene promoter methylaion could lead to a decrease or absence in the DACH1 expression in EC.The promoter methylation of DACH1 gene may induce the inhibition of DACH1 expression,which might be one of the mechanisms of DACH1 gene inactivation in human EC.

This paper introduces the development and implementation of hospital-community interactive nursing mode for patients with diabetes. The interactive mode between community and hospital,specialist nurses and community nurses,as well as patients and nurses was formed to provide timely,convenient,continuous and whole-process nursing care for diabetic patients through the setting up and services of hespital-based diabetes care team,two-way transfer center between hospital and commu-nity,hospital-based education and community-based visit team,community-based self-management group as well as green chan-nel of priority treatment,inspection and hospitalization for diabetic patients. The implementation of the interactive mode achieved good effect and was approved by the patients. The patient satisfaction rate was 96.5%.

In order to study the susceptibility of murine vaginal mucosa to Candida albicans under different conditions, vaginal lavage fluid and vaginal tissue of mice were observed and compared between murine models with normal immune system (estrogen-treated mice) and immunosuppressed murine model, and between primary infection model of vaginal candidiasis and secondary infection one. The average level of colony forming unit (CFU) from the immuosuppressed group was higher than that from estrogen-treated group at each time point and the peak time was delayed. The differences between the two groups were statistically significant (P < 0.05) from the fourth day after inoculation. A significant difference existed in the average level of CFU between the control group and the estrogen-treated group (P < 0.05), and between the control group and the immuosuppressed group (P < 0.01). It was concluded that the vaginal mucosa from the immunosuppressed mice is more susceptible to Candida albicans and no difference is found in susceptibility between mice with primary infection and secondary infection.

Objective To investigate nurses' presenteeism and job stressors, and explore the correlation between them. Methods From January to May in 2017, a total of 380 nurses were investigated in one classⅢ grade A hospital in He'nan and totally 349 valid questionnaires were included. Presenteeism Questionnaire and Nurses Job Stressors Scale were used to investigate nurses' presenteeism and job stressors. SPSS 21.0 statistical package was used to organize and analyze the data. Independent sample t-test and ANOVA, Pearson correlation analysis and multivariate linear regression analysis were used. Results For the 349 nurses, the score of presenteeism was(3.25±0.73) points. Presenteeism behavior score of married nurses was higher than that of the unmarried nurses; presenteeism behavior scores of different titles were different (t=2.655, F=2.830;P<0.05). The score of job stressors was (2.50±0.49) points, which belonged to the medium level. Correlation analysis showed that work environment, interpersonal management had no correlation with presenteeism behavior(P> 0.05) and the other relations between the two variables was positive (P< 0.05). Patient care, time allocation and workload, nursing profession and work had predictive effect on presenteeism behavior (P< 0.05). Conclusions The stressors of nurses in this study are at medium level. The stressors of nurses affect their presenteeism. Nursing managers should take measures to prevent and interfere with the stressors of nurses,reduce the frequency of nurses' presenteeism, promote their physical and mental health and improve the quality of nursing.
