RESUMO
Objective:To explore the effect of dialysis pipeline nursing group mode combined with predictive nursing measures on hemodialysis efficacy of diabetic nephropathy patients with maintenance hemodialysis (MHD).Methods:A total of 96 patients with MHD of diabetic nephropathy admitted to No. 904 Hospital of Joint Logistics Support Force of Chinese People's Liberation Army from January 2015 to December 2019 were selected as the research objects and divided into control group and observation group, 48 cases in each group. Patients in the control group were treated with routine dialysis pipeline and other hemodialysis nursing interventions, while patients in the observation group were treated with predictive nursing measures on this basis. The biochemical indexes, psychological state, compliance, incidence of nosocomial infection and complications and nursing satisfaction of the two groups before and after intervention were compared.Results:After the nursing intervention, the blood urea nitrogen (BUN), creatinine (Cr), and β2 microglobulin (β2-MG) of the two groups of patients were lower than those before the intervention, and the BUN of the observation group after the intervention, Cr and β2-MG were (12.04±1.98) mmol/L, (451.62±82.49) μmol/L, (13.53±2.31) mg/L, respectively, which were lower than those of the control group (15.82±2.31) mmol/L, (591.35±99.21) μmol/L, (18.83±2.92) mg/L, the difference was statistically significant ( t value was 8.608, 7.503, 9.862, P<0.05). After the intervention, the scores of the treatment compliance subscales of the observation group were 29.06±3.58, 23.42±2.99, 20.11±3.01, 14.76±2.94, which were higher than those of the control group (31.91±3.97, 21.53±3.21, 17.03±2.74, 12.36±3.04), the difference was statistically significant ( t value was 2.985-3.932, P<0.05). After the intervention, the SAS and SDS scores of the two groups were lower than those before the intervention, and the SAS and SDS scores of the observation group after intervention were 39.12±4.82 and 36.43±6.03, which were lower than those of the control group 48.25±5.14, 46.75±5.36, the difference was statistically significant ( t value was 8.997, 8.862, P<0.05). The incidence of nosocomial infections and complications in the observation group were 2.08% (1/48) and 4.17% (2/48), which were significantly lower than those in the control group, 14.58% (7/48) and 18.75% (9/48), The difference was statistically significant ( χ2 value was 4.91, 5.26, P<0.05). The nursing satisfaction degree of the observation group was 95.83% (46/48), which was higher than 72.92% (35/48) of the control group, and the difference was statistically significant ( χ2 value was 9.56, P<0.05). Conclusions:The dialysis pipeline combined with predictive nursing can improve the psychological state of patients, reduce the incidence of hospital infection and complications, prolong the service life of vascular access, improve the quality of life of hemodialysis patients, improve the relationship between nurses and patients, and create a harmonious atmosphere, which is worthy of clinical promotion and application.
RESUMO
Objective@#To investigate the correlation between the frequency and function of early plasmacytoid dendritic cells (pDC) and the treatment response in patients with HBeAg-positive chronic hepatitis B receiving entecavir (ETV).@*Methods@#Patients with HBeAg-positive chronic hepatitis B were enrolled. Antiviral therapy with ETV, serum serological markerso hepatitis B virs (HBV) infection and liver function (HBV DNA load, HBsAg/anti-HBs, HBeAg and anti-HBe levels, and ALT levels) were monitored every three months before and during treatment; the efficacy of ETV was assessed by changes in the level of HBV DNA. Peripheral venous blood was collected before treatment, at 12 weeks and 24 weeks, respectively. Flow cytometry was used to detect the frequency of peripheral blood pDC and the surface co-stimulatory molecule CD86. The baseline and early treatment (12 weeks and 24 weeks) pDC frequency and functional changes were analyzed.@*Results@#Of the 100 patients with chronic hepatitis B, 45 patients received ETV treatment and 48 weeks of follow-up. Within 48 weeks of ETV treatment, HBsAg levels decreased by 0.53±0.78 log IU/mL; HBeAg decreased by 816.61S/CO, and HBeAg seroconversion occurred in 4 cases; HBV DNA content decreased by 6.04±1.12 log IU/mL, in 33 cases (73%) the HBV DNA became undetectable, in 43 cases ALT kept normal continuously for more than 3 months. In the early stage of ETV treatment, pDC% increased significantly, CD86+ pDC%, CD86MFI and CD86ABC showed no significant changes. In ETV-treated HBV DNA responders, pDC% increased significantly, CD86+ pDC%, CD86MFI and CD86ABC showed no significant changes; HBV DNA non-responders had a significant increase in pDC%, but CD86+ pDC% decreased significantly, and CD86MFI and CD86ABC showed no significant changes. The decrease in HBsAg and HBeAg levels in ETV treated patients was not significantly associated with early pDC%, CD86+ pDC%, CD86MFI and CD86ABC changes.@*Conclusions@#ETV treatment can directly inhibit the replication of HBV DNA, but does not enhance the function of immune cells.
RESUMO
To explore the protective effects of right coronary artery ischemic preconditioning and post-conditioning on myocardial ischemia reperfusion injury in rabbit heart. Methods: A total of 30 rabbits were randomly divided into 4 groups: a control group (n=7), an ischemia reperfusion group (IR group, n=8), an ischemic preconditioning group (IPC group, n=8) and an ischemic post-conditioning group (IPO group, n=7). Venous blood samples were taken at pre-operation, 1 and 6 h post-operation, and the concentration of serum creatine kinase isoenzyme (CK-MB) and cardiac troponin-T (cTn-T) were measured. The infarct area of cardiac muscle was calculated. Results: Compared with the IR group, the levels of CK-MB and cTn-T at 1 and 6 h post-operation in the IPC group and the IPO group were reduced (all P<0.05). Compared with the IR group, the infarct size in the IPC group and the IPO group was significantly decreased, with significant difference (both P<0.05) . Conclusion: Right coronary artery ischemic preconditioning and post-conditioning exert significant protective effects on the myocardial ischemia reperfusion injury in New Zealand rabbits.
