Objective To evaluate the efficacy and safety of fludarabine and pirarubicin (FT) regimen in the treatment of refractory or relapsed indolent non-Hodgkin lymphoma (NHL). Methods A total of 40 patients with relapsed or refractory indolent NHL were treated with FT regimen, one cycle for 28 days, total 6 cycles. The data of indolent NHL patients treated with fludarabine, noventrene and dexamethasone (FND) regimen were collected as control. Results 40 patients were given 228 cycles chemotherapy, overall response rate was 62.5 %, median progression-free survival was more than 20 months and 2 years overall survival rate was 70.0 %. The main toxicities was leucopenia (80.0 %), but the incidence of WHO Ⅲ-Ⅳ leucopenia and pneumonia was less than that of in the control group, the rate were 12.5 % vs 29.0 % and 2.5 % vs 23.0 % respectively (P <0.05). Conclusion The efficacy of FT regimen was as good as FND regimen, but the incidence of leucopenia and pneumonia by Ⅲ-Ⅳ was lower in FT group than in FND group. So the FT regimen was an effective and safe second-line salvage regimen for relapsed or refractory indolent non-Hodgkin lymphoma.

The dynamic changes of cognitive function has been paid more and more attention by foreign scholars.Dynamic assessment based on ecological momentary assessment(EMA)can capture subtle changes in cognitive function and provide more comprehensive information for early identification and timely intervention of people with cognitive impairment, which is an effective supplement to traditional cognitive assessment.This paper reviewed the concept of ecological momentary assessment, its advantages in cognitive assessment, its feasibility and effectiveness, and its application status in the evaluation of cognitive function in the elderly, so as to provide a reference for making ecological assessment of the cognitive function for older adults that is in line with China's national conditions.

Objective To explore the parenting stress of mothers of children with developmental mental disorder and influencing factors.Methods A total of 1 06 mothers of children with developmental mental disorder were included in study group,and 1 06 mothers of normal children were included in control group between January 201 3 and December 201 4 in our hospital.The parenting stress of mothers in two groups was compared and influencing factors of parenting stress were analyzed.Results The score of parenting stress in study group and control group were (1 09.83 ±1 7.89)and (85.57 ±1 6.79)respectively.The difference between the two groups was statistically significant (t =1 0.1 80,P <0.01 ).The risk factors of parenting stress of mothers were family income and the severity of mental disorder in children.Conclusions Mothers of children with developmental mental disorder have more parenting stress.We should pay more attention to decrease the parenting stress of mothers by improving children′s symptoms and providing more social supports.

Objective:To explore the mediating role of self-perceptions of aging between frailty and cognitive function in community-dwelling older adults.Methods:From February to July 2021, a total of 528 elderly people in Xinxiang community were investigated with the frailty phenotype, the brief self-perceptions ageing questionnaire and the Mini-mental state examination(MMSE) scale.According to the MMSE total score and education level, the subjects were divided into cognitive impairment group (illiteracy≤17, primary school≤20, junior high school and above≤24, n=74) and cognitive normal group( n=454). SPSS 25.0 software was used for common method deviation test, descriptive statistics and correlation analysis, while AMOS 24.0 software was used to build structural equation model and Bootstrap method was used for intermediary effect test. Results:(1)The prevalence of cognitive impairment among the elderly in the community was 14.1%. The differences between the cognitively normal group and cognitively impaired group were statistically significant in terms of age, education, number of chronic diseases suffered and depression ( χ2=59.21, 6.53, 9.84, 25.47, all P<0.05). The differences were statistically significant in terms of frailty( χ2=75.65, P<0.001) and self-perceptions of aging ( t=77.67, P<0.001). (2)Self-perceptions of aging in the cognitively impaired group (47.39±8.66) was higher than that in the cognitively normal group (38.22±8.24) ( t=77.67, P<0.001) .Frailty score in cognitively impaired group (2.00 (1.00, 3.00)) was higher than that in the cognitively normal group (0.00 (0.00, 1.00))( Z=-8.63, P<0.001) . (3)Frailty was negatively correlated with cognitive function ( r=-0.492, P<0.01), and positively correlated with self-perceptions of aging ( r=0.540, P<0.01). Self-perceptions of aging was negatively correlated with cognitive function ( r=-0.541, P<0.01) . After controlling the influencing factors such as age, education level, chronic diseases and depression, the correlation was still significant (all P<0.01) . (4) Self-perceptions of aging played a partially mediating role in the relationship between frailty and cognitive function, the mediating effect accounted for 58.5% of the total effect. Conclusion:Frailty and self-perceptions of aging have a significant impact on the cognitive function of the elderly in the community, and self-perceptions of aging plays a partial intermediary role between the frailty and cognitive function of the elderly in the community.

Objective:To explore the effect of family empowerment program combined with deglutition exercises in patients with deglutition disorders.Methods:From February 2019 to February 2021, a total of 107 patients with deglutition disorders admitted to Xinxiang Central Hospital were enrolled by convenience sampling method and divided into the observation group (54 cases) and the control group (53 cases) using random number table method. The control group received routine nursing and deglutition intervention, and the observation group received family empowerment program combined with deglutition intervention on the basis of routine nursing. The standardized swallowing assessment (SSA) , mini nutritional assessment short-form (MNA-SF) , swallowing quality of life questionnaire (SWAL-QOL) scores and the incidence of adverse events of the two groups were compared before and after intervention.Results:After intervention, MNA-SF score and SWAL-QOL score of the observation group were higher than those of the control group, while SSA score, incidence of respiratory aspiration and aspiration pneumonia of the observation group were lower than those of the control group , the differences were statistically significant ( P<0.05) . Conclusions:The family empowerment program combined with deglutition exercises can improve patients' deglutition function and nutrition status, reduce the risk of respiratory aspiration and aspiration pneumonia, and improve patients' quality of life.
