Additionally, there was a positive correlation between interprofessional readiness and attitude (rs=0.282, P<0.001).ConclusionSophomore undergraduates are generally in a positive state of readiness for interprofessional learning as well as attitude towards interprofessional collaboration, and there is a positive correlation between interprofessional readiness and attitude, suggesting that it is worth considering to carry out interprofessional education activities among medical sophomore undergraduates.
Objective To define the attributes and priorities of evidence-based nursing curriculum needs of nursing students, so as to provide operational reference for the design and development of evidence-based nursing course in the future. Methods Questionnaire was designed based on Kano model, and convenient sampling method was adopted to investigate the nursing students who had received training or had experience in evidence-based nursing from September to November 2020. According to the Kano model attribute classification method, the need attribute of evidence-based nursing curriculum was defined. Results A total of 303 nursing students were investigated. Kano model analysis showed that 11 of the needs for evidence-based nursing courses were one-dimensional quality, which belonged to the dimension of teaching resources and teaching content, and 5 were indifference quality, which belonged to the course assessment dimension. The importance-satisfaction matrix showed that the need of evidence-based nursing curriculum was concentrated in the advantage area and minor excepting improvement area. Conclusions In the future curriculum design, evidence-based nursing teachers need to continue to maintain the demand items in the advantage area and constantly improve and perfect them. They also need to pay more attention to the demand items in the minor excepting improvement area. Combined with the current problems in evidence-based nursing practice and the evidence-based needs of students, teachers need to further put forward suggestions on evidence-based nursing curriculum.
Abstract： Objective To investigate and improve the method of isolation, induction and culture, amplification in vitro of human endothelial progenitor cells (EPCs) in human bone marrow, thus establish a foundation for EPCs to participate in basic research and clinical application. Methods WHuman bone marrow mononuclear cells (hBMMNCs) were isolated by density gradient centrifugation and cultured in the 6plateds coating human fibronections(HFN group), coating gelatinum (coating gelatinum group) and coating nothing (coating nothing group) respectively. After culturing for 4-7d endothelial cell basal medium-2(EBM-2) cell colonyforming units (CFUs) appeared, then select EPCsliked CFUs for cultivation which was named the pick method, CD34+ KDR+ and CD133+ KDR+ double positive cells were detected in flow cytometry, and CD133, CD34, CD31, vWF and KDR expression were detected with cell immunochemical test.

Methods Ninety CKD patients treated in our hospital between November 2009 and December 2010 were randomly divided into two groups. One group was given rosuvastatin calcium 10 mg/d, which the other group was given atorvastatin calcium 10 mg/d. The two groups matched in terms of age and gender. We determined blood leukocyte (WBC), high sensitivity reactive protein (hs-CRP), fibrinogen (FIG), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) of the patients before and after treatment for 12 weeks. Results The inflammatory marker levels of both groups before treatment had no significant difference (Pgt;0.05). The inflammatory marker levels of two groups after treatment for 12 weeks were significantly decreased compared with the levels before treatment (Plt;0.01), and rosuvastatin calcium group decreased more apparently than atorvastatin calcium group. Conclusion Rosuvastatin can improve the anti-inflammatory response in CKD patients.
ObjectiveTo explore the characteristics of blood pressure variability (BPV) in maintenance hemodialysis (MHD) patients with and without diabetes mellitus and the effects of BPV on cardiac function based on the research of clinical data. MethodsOne hundred MHD patients treated in the Hemodialysis Center of the People’s Hospital of Taixing City between January 2013 and January 2015 were recruited and divided into diabetes group (n=46) and non-diabetes group (n=54). Interdialytic and intradialytic BPV and cardiac function were monitored and compared between the two groups. Standard deviation (SD) and coefficient of variation (CV) were used for the evaluation of BPV. ResultsTriacylglycerol, cholesterol and plasma albumin were significantly different between the diabetes group and non-diabetes group (P<0.05), while hemoglobin, serum calcium, phosphorus and parathyroid hormone were not significantly different between the two groups (P>0.05). Forty-two patients in the diabetes group and 53 in the non-diabetes group took antihypertensive drugs. The varieties of antihypertensive drugs and the proportion of patients who used antihypertensive drugs were not significantly different between the two groups. The ambulatory blood pressure monitoring displayed 40 patients (86.9%) with reverse dipper or non-dipper blood pressure in the diabetes group and 35 (64.8%) in the non-diabetes group, and the difference was significant (P<0.05). The interdialytic mean systolic blood pressure (SBP), SBP-SD and SBP-CV in the diabetes group were all significantly higher than those in the non-diabetes group (P<0.05), and the mean diastolic blood pressure (DBP), DBP-SD and DBP-CV were also significantly different between the two groups (P<0.05). The intradialytic mean SBP, SBP-SD and SBP-CV in the diabetes group were significantly higher than those in the non-diabetes group (P<0.05), but there were no significant differences in intradialytic mean DBP, DBP-SD and DBP-CV between the two groups. In patients with reverse dipper or non-dipper blood pressure, the interventricular septal thickness, left ventricular end-diastolic diameter and ejection fraction were significantly different between the diabetes group and the non-diabetes group. However, in patients with dipper blood pressure, the cardiac function parameters were not significantly different between the two groups. Conclusion MHD patients with diabetes have higher ratio of reverse dipper or non-dipper blood pressure, more significant blood pressure variability and more severe cardiac function damage.
Objective To explore the effectiveness of passive immunization of fetus via mother on preventing the transmission of HBV from mother to infant. Methods A prospective randomized controlled study was designed. Fifty-two HBeAg positive pregnant women were randomly allocated to two groups, of which 28 women were allocated to trial group, and injected with 200 IU of hepatitis B immune globulin (HBIG) for 1 injection at the 28th, 32nd and 36th weeks of pregnancy respectively, 24 women allocated to control group were given no injection of HBIG. The samples of cord blood from the newborns in two groups were collected and tested for HBeAg and HBV-DNA by ELISA and FQ-PCR. Results The rates of HBeAg positive in the newborns were 21.4% in trial group, 79.2% in control group. There was statistically significant difference between two groups ( χ2=17.26, Plt;0.01, RR=0.27). The rates of HBV-DNA positive in newborns were 25.0% in trial group, 83.3% in control group, showing statistically significant difference between the two groups (χ2=17.62, Plt;0.01, RR=0.30). In the trial group, there were 21 newborns with HBV-DNA negative, 7 with HBV-DNA positive. HBV-DNA quantities were significantly lower in 7 newborns than in their mothers (T=28, P=0.02, Wilcoxon test). Conclusions Multiple injections of HBIG to pregnant women with HBeAg positive before labor could greatly reduce mother-infant transmission of HBV.
