RESUMEN

Hospice care requires all-round care provided by medical staff for end-stage patients. Due to the particularity of its objects, nursing staff need to have a broader vision and practice ability, so as to play a professional role in the care of end-stage patients and their families. By combing the core elements of nursing staff’s hospice care practice ability, this paper analyzed the influencing factors of nursing staff’s hospice care practice ability, systematically summed up the intervention measures to improve nursing staff’s hospice care practice ability, and put forward the cultivation prospect and development expectation of nursing staff’s hospice care practice ability in China, so as to lay the foundation for the management and training of hospice care nursing staff.

RESUMEN

Objective To study the diagnosis value of serum retinol binding protein (RBP),cystatin C(Cys C) and β2 microglobulin (β2-M) in early renal injures of gcstational diabetes mellitus (GDM) patients.Methods 85 case of GDM pregnant women admitted to Shiyan Maternal and Child Health-Care Hospital from Jan.2009 to Jan 2015 were chosen as research objects,and were divided into simple diabetes group (35 cases),micro proteinuria group (30 cases) and massive proteinuria group (20 cases) according to the urinary albumin excretion rate (UAER),while 30 cases of healthy pregnant women were recruited randomly during the same period as control group.The 24h urine protein,serum RBP and renal function indicators [blood urea nitrogen (BUN),creatinine (Ser),Cys C and β2 M],the positive rates of RBP,Cys C,β2-M and combined detection of RBP,Cys C,β2-M of the four groups were compared.Results The 24h urine protein in simple diabetes group,micro proteinuria group and massive proteinuria group were significantly higher than that in the control group (t=3.91~ 16.33,all P<0.01),the difference between the 3 groups were statistically significant (t=6.78~ 16.94,all P<0.01).The levels of BUN,Scr,Cys C,β2-M and RBP in micro proteinuria group and massive proteinuria group were significantly higher than those in control group and simple diabetic group (t=3.68 ~ 18.54,all P<0.01),there were significant difference in above indexes between micro proteinurine group and massive proteinuria group (t=4.70~ 10.87,all P<0.01).The positive rates of RBP,Cys C,β2-M and combined detection of RBP,Cys C and β2-M in micro proteinuria group and massive proteinuria group were significantly higher than those in control group and simple diabetic group (x2 =20.27~38.57,all P<0.01).There was no significant difference in the positive rates between micro proteinuria group and massive proteinuria group (x2 =0.62~0.93,all P>0.05).The positive rate of combined detection of the three indicators was higher than that of the single detection in the same group (x2=3.97~6.65,P<0.05 or P<0.01).Conclusion The detection of serum Cys C,RBP and β2-M has a high clinical value in the diagnosis of early renal damage in patients with GDM.The positive rate of combined detection of 3 indexes was higher than that of single index.

RESUMEN

Objective: To investigate arsenic trioxide (As 2O 3) -target interactions at the level of nuclear matrix (NM) in chronic myelogenous leukemia cell line K562 by proteomics. Methods: DNA fragmentation analysis was used for As 2O 3 induced apoptosis of K562 cells. The nuclear matrix proteins were analyzed by high-resolution two-dimensional gel electrophoresis and computer-assisted image analysis. Results: While more than 200 protein spots were shared among the nuclear matrices, about 18 distinct spots were found characteristic of As 2O 3 treated cells. Onset of mass mange apoptosis, and the profiling of nuclear matrix proteins had been alternated and it was a more sensitive indicator than nucleosomal DNA fragmentation against As 2O 3 treatment. Conclusion: As 2O 3 induced apoptosis in K562 cells in a dose-time-dependent manner. As 2O 3 might be clinically useful in treatment of chronic myelogenous leukemia and the changes of nuclear matrix proteins in the treated cells can be used as a useful indicator for the treatment.

RESUMEN

<p><b>OBJECTIVE</b>To investigate arsenic trioxide (As(2)O(3))-induced apoptosis and the effects on cell nuclear matrix related protein promyelocytic leukaemia (PML).</p><p><b>METHODS</b>HepG2 cells were cultured in MEM medium and treated with 0.5, 2, 5 and 10 micro mol/L As(2)O(3) for either 24 h or 96 h at each concentration. In situ terminal deoxynucleotidyl transferase (TdT) labeling (TUNEL) and DNA ladders were used to detect apoptosis. Confocal microscopy and Western blotting were used to observe the expression of PML.</p><p><b>RESULTS</b>The growth rates of HepG2 cells were slower in the As(2)O(3) treated than the untreated control group. DNA ladder and TUNEL positive apoptotic cells could be detected in As(2)O(3) treated groups. The expression of PML decreased in HepG2 cells with 2 micro mol/L As(2)O(3) treatment. Confocal images demonstrated that the expression of PML protein in HepG2 cell nuclei decreased after treatment with 2 micro mol/L As(2)O(3), and micropunctates characteristic of PML protein in HepG2 cell nuclei disappeared after treatment with 5 micro mol/L As(2)O(3).</p><p><b>CONCLUSIONS</b>Our results show that arsenic trioxide can significantly inhibit the growth of HepG2 cells in vitro. As(2)O(3) induces apoptosis in HepG2 tumor cells in a time and concentration dependent manner. As(2)O(3) may degrade the PML protein in HepG2 cell nuclei. The decreased expression of PML in As(2)O(3) treated tumor cells is most likely to be caused by apoptosis. Nuclear matrix associated protein PML could be the target of As(2)O(3) therapy.</p>
