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.

Bipolar disorder is a common, highly disabling psychiatric disorder characterized by early onset, frequent episodes, high suicide risk, and chronic outcomes, and is associated with severe social dysfunction. The pathogenesis of bipolar disorder is still unclear, and current studies mainly focus on circadian rhythm abnormalities, including rhythm gene mutation, polymorphism, abnormal kinase expression, and rhythm abnormalities in neurotransmitter secretion and transport. It has been found that at any stage of bipolar disorder, whether prodrome, episode, or remission, patients exhibit circadian rhythm disruptions, including disrupted sleep-wake cycles, hormonal phase abnormalities, and irregular social rhythms. Based on this mechanism, the time therapy, such as light therapy, dark therapy, sleep deprivation and behavioral intervention, can rapidly improve the circadian rhythm of patients with bipolar disorder, achieve the goal of rapid relief of symptoms, with fewer side effects, low risk of switching to manic. In this paper, circadian rhythm mechanism, clinical manifestations and chronotherapy of bipolar disorder are reviewed to provide a basis for clinical diagnosis and treatment.
