ABSTRACT
Objective:To explore the clinical effect of multidisciplinary cooperative intervention in improving self-management and improving fluid retention in the elderly patients with chronic heart failure.Methods:Totally 130 cases of the elderly patients with chronic heart failure from January to December 2018 were enrolled and were divided into control group and observation group with 65 cases randomly. The control group received routine nursing instruction and telephone follow-up. The observation group was given multidisciplinary team guidance to patients self-management in addition to routine nursing instruction and telephone follow-up. After 3 months, the self-management and fluid retention of the two groups were compared.Results:After 3 months of intervention, the scores and total scores of the observation group in the four dimensions of drug management, diet management, psychological and social adaptation management, symptom management were 19.43±0.71,11.51±0.59,19.07±0.65,25.24±1.31, 72.65±7.16, the control group was 11.09±3.40, 6.05±1.71, 12.73±2.49, 15.72±4.18, 46.35±7.83. The scores and total scores of the observation group were better than those of the control group ( t value was 4.835-13.727, all P < 0.05).After intervention for 3 months, the proportion of severe edema, moderate edema and mild edema in the observation group was 4.61% (3/65), 13.85% (9/65), 81.54% (53/65), respectively, and the control group was 38.46% (25/65), 52.31% (34/65) and 9.23% (6/65) respectively. The degree of fluid retention in the observation group was better than that in the control group ( Z value was -2.373, all P < 0.05). Conclusion:Multidisciplinary cooperative intervention can improve self-management and improve fluid retention in elderly patients with chronic heart failure.
ABSTRACT
Objective To investigate the impact on image quality of bone imaging and patients safety when whole body bone imaging was performed on the sme day of renal dynamic imaging.Methods Fifty-three adult patients underwent renal dynamic imaging and whole body bone imaging were selected as observation group.Firstly,99 Tcm-DTPA renal dynamic imaging was performed,and 2 h later,99Tcm-MDP was injected,then whole body bone imaging was performed according to technological process.The other 53 patients received bone imaging only were selected as control group.After injection of 99Tcm-MDP immediately and 30 min,1 h,2 h,4 h,6 h,and 24 h later,physiological response of all patients was observed,and image quality of bone imaging between the two groups was compared.Then the ratio of subjective excellent images of the two groups was calculated.Radioactivity counting of T12,L4,iliac crest,middle humerus,middle femur and soft tissue above 2 cm of ilium on posterior image was measured,and target/non target (T/NT) was calculated.Statistical analysis was performed on the two groups.Results Adverse reaction was not found in all patients in two groups.Subjective excellent rate was 90.57％ (48/53) in observation group,and 92.45％ (49/53) in control group (x2 =0.12,P＞0.05).T/NT of T12,L4,middle humerus and middle femur had no significant differences between two groups (all P＞0.05).The difference of T/NT of iliac crest was statistically significant between two groups (t=3.45,P＜0.05).Conclusion Radionuclide renal dynamic imaging on the same day has no significant impact on the image quality of whole body bone imaging.
ABSTRACT
Objective To investigate the impact of preload fasting and meal replacement in patients with metabolic syndrome.Methods A total of 92 subjects with metabolic syndrome were enrolled in the study.They were assigned into the preload fasting group (PFG),the meal replacement group (MRG),and the control group (CG) for 12-weeks intervention.Special dietary with 100 kcal was provided 30 min before each meal in the PFG,and while in the MRG the same dietary was taken just before each meal and the amount of meal was reduced appropriately.The subjects in CG took meals as usual.Body mass index,waist circumference,and insulin resistance were assessed.Satiety situation was investigated by the scale.Results After 12 weeks,improvement were found in fasting insulin(-3.29 mU/L) and waist circumference (-4.04 cm) in the PFG and significant difference was shown compared to the CG (P＜0.05).Satiety index in the PFG was the most significant among the three group.Conclusion Preload fasting is helpful in improving insulin resistance,reducing waist circumference,and enhancing satiety.
ABSTRACT
Objective To explore the mechanism that gold nanorods trigger apoptosis in cancer cells.Methods Gold nanorods was synthesized by gold seed growing method, and its characterization was detected; gold nanorods on cell proliferation-toxicity were evaluated by CCK-8 Kit and apoptosis were detected by flow; mitochondrial membrane potential were tested by JC-1 and activation of Caspase 9 and Caspase 3 were detected by western blot. Results The results found that gold nanorods had nontoxic to normal cells, but highly toxic to tumor cells; and with the increasing of gold nanorods’ working time, the percentage of apoptotic cancer cells was increasing; in addition to, normal cells’ mitochondrial membrane potential did not change, but cancer cells had a significant reduction in mitochondrial membrane potential.Conclusion This study proves that gold nanorods induce apoptosis through the mitochondrial apoptosis pathway.
ABSTRACT
Objective To construct,express and analysis the antitumor activity of anti-EGFR ScFv(HL-L-L),and analyze bioinformatics and characterize correlation spectroscopy.Methods EGFR ScFv(HL-L-L)gene was obtained by OVER LAPING technology and construction of prokaryotic expression vector pET-28a-c(+)-VH-L-L.After induced expression,target protein HL-L-L was purified by Ni column,and its tertiary structures was predicted with SWISS - MODEL;size distribution and zeta potential distribution of the target protein HL-L-L were characterized by NanoZSP;the inhibition effects of HL-L-L on breast cancer cell proliferation were studied with the method of pharmacology.Results Prokaryotic expression vector pET-28a-c(+)-VH-L-L was constructed successfully,high purity of protein HL-L-L was obtained,and successfully predicted its three-dimensional structure;the size was about 489.7 nm,and the Zeta potential was 38.1 ,negatively charged.It had a certain inhibition effect on MCF # 7 proliferation,compared with blank group,and the difference was significant(P<0.01 ).Conclusion This study successfully express all anthropogenic medicinal anti-EGFR ScFv(HL-L-L),which has significant inhibiting effect on breast cancer cell proliferation.It provides the foun dation for further development of small molecules of anti-EGFR antibody drug.
