RESUMEN
Objective:To understand the current situation and demand of intracavity electrocardiographic positioning technique training for PICC specialist nurses in Shandong Province, and provide a reference for further improving and improving the training of PICC specialist nurses.Methods:From July 7-23, 2019, a total of 903 PICC specialist nurses in Shandong Province were selected by the convenience sampling method. The nurses were investigated by the self-made general information questionnaire of PICC specialist nurses in Shandong Province and the training demand questionnaire of intracavity electrocardiographic positioning technique.Results:40.75% (368/903) PICC specialist nurses had participated in intracavity electrocardiographic positioning technique training; 84.27% (761/903) PICC specialist nurses thought it necessary to conduct intracavity electrocardiographic positioning technique training. PICC specialist nurses had various training on intracavity electrocardiographic positioning technique, the average content requirements were all above 4.67 points. The highest score of theoretical training content was the judgment of the relationship between catheter tip position and electrocardiogram P wave (4.80 ± 0.47), and the highest score of operation training content was the intracavitary electrocardiography guided PICC catheterization (4.74 ± 0.55). 94.24%(851/903) PICC specialist nurses hoped to achieve the goal of improving clinical nursing practice ability through intracavity electrocardiographic positioning technique training. Intravenous therapy specialist academic conference was the main hoped training form(76.85%, 694/903). Multiple regression analysis showed that the number of years of catheterization, job position and understanding of the technology were the influencing factors of PICC specialist nurses′ training needs for intracavity electrocardiographic positioning technique ( t = -3.73,3.12, -3.63, all P<0.05). Conclusions:The training rate of intracavity electrocardiographic positioning technique was low, but PICC specialist nurses had higher training requirements for intracavity electrocardiographic positioning technique. Managers should pay attention to the training of intracavity electrocardiographic positioning technique, and develop targeted training programs to further improve the clinical practice capabilities of the PICC specialist nursing team.

RESUMEN
ObjectiveTo study the effects of perindopril on myocardial energy metabolism and ultrastructural changes in rats with chronic heart failure (CHF) induce by isoproterenol. MethodsTotally 55 male SD rats were randomly (random number) divided into two groups, namely control group (Group C) and CHF model group. The CHF rat models were made by subcutaneous injection of isopreteronol (ISO) in doses of 20 mg · kg-1 · d-1, 10mg · kg-1 · d-1 and 5 mg/kg/d for successive 3 days and then 3 mg· kg-1· d-1 for9 days. Four weeks later, the rats in CHF model group were randomly further divided into two subgroups, namely untreated subgroup (group M ) and perindopril treated subgroup (group P). After treatment for five weeks in average, echocardiography and myocardial pathology examination carried out to assess the cardiac function and structure changes of these rats. The levels of ATP, ADP, AMP, lactic acid (LA) and sarcoplasmic reticulum Ca2+ -ATPase (SERCA) activity in myocardium were determined by enzymatic reaction. ResultsCompared with rats in group M, the ejection fraction of left ventricle (EF) and fractional shortening of short axis of left ventricle (FS) of the rats in group P increased by 3.25％ and 7. 33％, respectively. Compared with rats in group C, the myocardial ATP, AMP, TAN (total adenosine) and LA significantly decreased in rats of group M. There were no significant differences in the levels of ADP, AMP, ATP/ADP and TAN between group C and group P (P ＞0. 05). Compared with rats in group M, the myocardial SERCA activity increased by 16. 41％ in rats of group P. The myocardial injury found under microscope and electronic microscope was ameliorated by treatment with peidolapril in rats of group P in comparison with rats of group M. ConclusionsPerindopril can improve myocardial energy metabolism,and lessen the pathological changes of ultrastructure, enhancing the cardiac function of rats with CHF induced by ISO.

BACKGROUND: Previous studies found that C57BL/6 mouse was susceptible to atherosclerosis, while BALB/c mouse was resistant to atherosclerosis. The stenosis of the culprit vessel and the severity of myocardial infarction were correlated to the levels of OX40L expression. Whether OX40L has differential expression between C57BL/6 and BALB/c mouse was not identified.OBJECTIVE: To observe the differential expression of OX40L mRNA and protein in C57BL/6 and BALB/c mouse.METHODS: Total RNA and protein were extracted by Trizol and RIPA Buffer from heart, brain, kidney, skeletal muscle and spleen tissues of C57BL/6 and BALB/c mice. RT-PCR and Western Blot were used to detect OX40L mRNA and protein expression in heart, brain, kidney, spleen and skeletal muscle of two kinds of mice. The differential expression of OX40L mRNA and protein between C57BL/6 and BALB/c mice was observed.RESULTS AND CONCLUSION: RT-PCR results showed that the mRNA expression level of OX40L in heart of C57BL/6 mice mouse was significantly higher than BALB/c mice (P ＜ 0.05); the mRNA expression level of OX40L in spleen of BALB/c mice was significantly higher than C57BL/6 mice (P ＜ 0.05). There were no significant differences in the brain, kidney and skeletal muscle between these two strains. The results of Western Blot showed that the protein expression level of OX40L in heart, brain and kidney of C57BL/6 mice were significantly higher than BALB/c mice (P ＜ 0.05). There were no significant differences in skeletal muscle and spleen between these two strains. The OX40L mRNA transcription level in heart was higher in C57BL/6 mouse than BALB/c mouse, while the expression in spleen was lower than the latter. The OX40L protein levels in C57BL/6 mouse heart, brainand kidney were higher than BALB/c mouse. The differences of OX40L expression between the two strains of mice indicated that OX40L may promote to C57BL/6 mouse susceptible to atherosclerosis.
RESUMEN
Abnormalities of diastolic function are common to virtually all forms of cardiac failure. However, the molecular events leading to diastolic dysfunction have not been fully elucidated. We performed a differential proteomic profiling study on diastolic dysfunction hearts induced by renovascular hypertension. Left ventricular diastolic dysfunction induced by renovascular hypertension (2K1C, two-kidneys, one clip) was performed in twelve Sprague-Dawley rats. 2D echocardiographic and cardiac protein patterns (2D-electrophoresis and mass spectroscopy) were compared with the sham operated rats. We described sixteen altered protein spots in 2K1C rats with left ventricular diastolic dysfunction. Calsarcin-1 (CS-1) was significantly down-regulated in 2K1C rats and it showed a negative correlation with calcineurin enzymatic activity (r(2)=0.72 p=0.03). We also showed changes in cellular energy metabolism in 2K1C rats, and these changes go in parallel with alterations of the thin filament proteome responsible for actin-myosin cross-bridge. In conclusion, this study provides a new insight into the left ventricular proteome profile associated with systemic hypertension induced diastolic dysfunction in a renovascular hypertension rat model. The decreased CS-1 protein with a concomitant increased enzymatic activity of calcineurin, suggests an important role of CS-1 in the calcineurin-mediated left ventricular hypertrophy.
