Objective:To explore the status quo and influencing factors of anxiety among caregivers of children with cancer during chemotherapy to provide a reference for clinical intervention.Methods:In this cross-sectional study, 133 caregivers of children with cancer during chemotherapy admitted at the First Affiliated Hospital of Zhengzhou University between May and August 2020 were selected by convenient sampling and investigated with the General Information Questionnaire, Generalized Anxiety Disorder-7 (GAD-7) , and Chinese version of Cognitive Fusion Questionnaire (CFQ) . In this study, a total of 133 questionnaires were distributed and 124 valid ones were returned, accounting for an effective response rate of 93.2%.Results:The GAD-7 score of the 124 caregivers was 10.50 (6.00, 15.75) ; the incidence of anxiety was 84.68% (105/124) ; and the Chinese version of CFQ score was 42.00 (32.00, 50.00) . There was a positive correlation between the GAD-7 and CFQ scores ( r=0.639, P<0.01) . Binary logistic regression analysis showed that cognitive fusion was a risk factor for anxiety among caregivers of children with cancer during chemotherapy ( P<0.01) . Conclusions:The anxiety and cognitive fusion levels among caregivers of children with cancer during chemotherapy are relatively high and positively correlated with each other. Targeted interventions should be provided in clinical practice for the cognitive fusion of caregivers of children with cancer during chemotherapy to reduce their anxiety and improve the quality of care for children.

Objective:To explore the effect of the training model based on the National Telemedicine Center in the technical training of children's implantable venous access port.Methods:Using the convenience sampling, 42 nurses who participated in the technical training of children's implantable venous access port in the First Affiliated Hospital of Zhengzhou University from May 2019 to December 2019 were selected as the study group. A total of 36 nurses who participated in the technical training of children's implantable venous access port in the First Affiliated Hospital of Zhengzhou University from December 2018 to March 2019 were retrospectively selected as the control group. The control group received the traditional training, and the study group implemented the training model based on the National Telemedicine Center. The theoretical assessment, operational assessment and training satisfaction were compared between the two groups before and after training.Results:After training, the theoretical assessment, operational assessment and training satisfaction scores of the study group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The training model based on the National Telemedicine Center in the technical training of children's implantable venous access port can enhance the professional knowledge and practical skills of nurses and improve the training satisfaction.

ObjectiveTo explore the correlation between post-traumatic stress disorder(PTSD) and emotional regulation in the parents whose children have acute lymphoblastic leukemia(ALL). MethodsBy convenient sampling method, a total of 233 parents whose children had ALL were selected in the First Affiliated Hospital of Zhengzhou University from June 2013 to June 2017, and the levels of PTSD and emotional regulation were evaluated by The PTSD Checklist-Civilian Version (PCL-C) and Emotion Regulation Questionnaire(ERQ). A total of 233 questionnaires were distributed and 233 valid ones were retrieved, yielding an effective recovery rate of 100%. ResultsIn this study, the participants got (35.82±4.93) points for PCL-C, among which the highest average item score was (2.29±0.36) points for "Avoid/Numb"; the score of "cognitive reappraisal" and"expressive suppression" were (4.27±0.64) and (4.35±0.60) points in ERQ. Pearson correlation analysis showed that the total score and each dimension score in PCL-C were negatively correlated with cognitive reappraisal (P＜0.05), and were positively correlated with expressive suppression (P＜0.05). Multivariate linear regression analysis showed that cognitive reappraisal and expressive suppression were the influencing factors for PTSD of the parents with ALL children (P＜0.05). ConclusionsALL children's parents have serious PTSD and tend to choose the emotional regulation way of expressive suppression. There is correlation between the degree of PTSD in ALL children's parents and their emotional regulating ability, therefore, nursing staff should assist them in the improvement of their emotional regulation ability to reduce the level of PTSD.

Objective To investigate the factors affecting the efficacy of leflunomide combined with medium/low dose corticosteroids in the treatment of progressive IgA nephropathy (IgAN).Methods Clinical and pathological parameters were collected retrospectively in patients of primary IgAN with proteinuria＞ 1.0 g/24 h and chronic kidney disease (CKD) stage 1-3 treated with leflunomide combined with medium/low dose corticosteroids in Ren Ji Hospital,School of Medicine,Shanghai Jiao Tong University from Jan 2005 to Dec 2010.According to the treatment effects,patients were divided into complete remission group and non-complete remission group.The biochemical and pathological indexes of the two groups were compared.Results A total of 42 patients were included.The remission rates at 3,6,9 and 12 months were 62％,64％,67％ and 74％,respectively.Seventeen (40.5％) and fourteen (33.3％) patients achieved complete and partial remission after one-year treatment,and the remission rate remained stable within one year after withdrawal of drugs.The 24hour proteinuria was 1.50 (0.67,2.66) g,which was significantly reduced compared with the baseline 2.44 (1.36,3.74) g (P ＜ 0.01).The decrease rate was 31.3％.There was a slight decrease in proteinuriawithin one year after withdrawal of drugs.Estimated glomerular filtration rate (eGFR) remained stable during the treatment and a year of follow-up.No serious adverse event was observed during the followup period.Among 31 responder patients,6(19.4％) patients relapsed.Logistic multivariate regression analysis suggested that the degree of renal interstitial inflammatory infiltration was an independent predictor of complete remission with one-year treatment of leflunomide combined with medium / low dose corticosteroids (HR=0.067,95％ CI 0.008-0.535,P=0.011).Conclusions IgAN treated with leflunomide and medium/low dose corticosteroids can achieve remission in early stage,and the remission rate remains stable after withdrawal of drugs.It is a safe option for the treatment of IgAN.Renal interstitial inflammatory infiltration is an independent predictor of complete remission.

Objective To validate the effect of Renji acute kidney injury score (RAKIS) on predicting patients with acute kidney injury (AKI) after cardiac surgeries,and make comparison with Cleveland score,simplified renal index (SRI) and acute kidney injury following cardiac surgery (AKICS).Methods Patients undergoing open heart surgery from 2008/01/01 to 2010/10/31 in Renji hospital were enrolled,and their scores of those four scoring models were calculated.AKI patients were diagnosed by KDIGO,and those scores of AKI patients and non-AKI patients were compared.Receiver operating characteristic (ROC) curve and area under curve (AUC) were used to decide the predictive values of those models.Results A total of 1126 patients were chosen in this cohort,with the average age of (58.43±14.88) years (rang from 18 to 88).The male to female ratio was 1.47:1.And 355(31.5％) patients were developed AKI.AKI stage Ⅰ,Ⅱ and Ⅲ were 65.4％,23.7％ and 11.0％ respectively.RAKIS was significantly higher in AKI patients than in non-AKI patients (17.5 vs 9.0,P ＜ 0.001).The AUCs of RAKIS to predict AKI,AKI Ⅱ-Ⅲ stages,renal replacement therapy (RRT)and in-hospital death were 0.818,0.819,0.800 and 0.784 respectively.The AUCs of Cleveland score and SRI were 0.659 to 0.710,lower than those of RAKIS and AKICS.AKICS had lower value for predicting AKI and AKI Ⅱ-Ⅲ stages (AUC 0.766 and 0.793),but good value in predicting RRT and inhospital death after surgery (AUC 0.804 and 0.835) as compared with RAKIS.Conclusions RAKIS is valid and accurate in the discrimination of KDIGO defined AKI patients,while for predicting the composite end point,AKICS may be more useful.

Objective To explore the association of fibroblast growth factor-23 (FGF23) with abdominal aortic calcification(AAC) and adverse outcomes in maintenance hemodialysis patients.Methods One hundred and fourteen cases of MHD patients were collected prospectively.Serum intact FGF23 was detected by ELISA.Abdomen lateral plain was used as a criteria to determine the abdominal aortic calcification and the abdominal aortic calcification score was counted.Logistic regression analysis was used to determine the risk factors of AAC.Kaplan-Meier analysis was applied to compare the survival rate among different groups and COX regression analysis was used to determine the association of FGF23 and mortality in MHD patients.Results Seventy-six patients present abdominal aortic calcification.The median of AACS was 4.0(0.0,11.0).The median level of FGF23 was 7277.4(2535.0,9990.8) pg/ml.The median follow-up duration was 72.0(67.8,72.8) months.During the follow-up,22 patients (19.3％) died of all-cause death and 17 cases (14.9％) died of cardiovascular diseases.Serum FGF23 level was positively correlated with AAC (r=0.285,P=0.002).Logistic regression analysis showed that longer age (OR=1.059,95％CI:1.020-1.100,P=0.003) and dialysis vintage (OR=I.009,95％CI 1.000-1.017,P=0.039),smoking history (OR=3.010,95％CI 1.177-7.696,P=0.021) and higher FGF23 level(OR=2.831,95％CI 1.010-7.937,P=0.048) were independent risk factors of moderate to severe AAC in MHD patients.Kaplan-Meier survival curves showed that the patients with AACS≥ 5 had significantly higher all-cause mortality(P=0.028) and CVD mortality (P=0.035) than those with AACS ＜ 5.However,the Kaplan-Meier analysis showed no significant difference regarding the level of serum FGF23 with the all-cause and CVD mortality.Cox regression demonstrated that FGF23 was not associated with increased mortality risk,neither in crude nor in multivariate adjusted models.Conclusions Abdominal aortic calcification had a high prevalence in MHD patients.The all-cause and CVD mortality was higher in patients with moderate to severe AAC.FGF23 was an independent risk factor of moderate to severe AAC,but it can't yet be a predictor for the allcause and CVD mortality of MHD patients.

Objective To determine the relationship between serum soluble Klotho (sKL) level and adverse outcome in maintenance hemodialysis (MHD) patients.Methods One hundred and twenty nine cases of MHD patients were collected prospectively.Serum sKL was detected by ELISA.Abdomen lateral plain was used as a criterion to determine the abdominal aortic calcification.The abdominal aortic calcification score (AAC) was calculated.Cox regression analysis was used to determine the risk factor of cardiovascular death (CVD) in MHD patients.Kaplan-Meier showed the relationship between sKL and CVD in MHD patients.Results There were 27 cases (20.9％) of allcause death and 19 cases (14.7％) of cardiovascular death.The median sKL was 612.6(379.2-816.6) nig/L,and log[iPTH] was an independent factor of sKL concentration.Low sKL had high AAC and CVD death rate.Kaplan-Meier method showed that the all-cause death rate was similar between two groups,and CVD death rate increased significantly in low sKL patients (P=0.036).Cox regression indicated that lower sKL level was associated with high CVD death rate [OR=0.352,95％CI(0.127-0.977),P=0.045].After adjustment for the general condition,biochemical indicators,the relationship still existed [OR=0.331,95％ CI (0.117-0.933),P=0.037].In no or mild vascular calcification patients (AAC ≤4),compared with high sKL patients,low sKL patients had no significant difference rate in all-cause mortality.The CVD mortality was significantly higher in high sKL (P=0.035) compared with low sKL.In severe calcification group (AAC ＞ 4),all-cause death and CVD death rates were similar between different sKL groups (P=0.991 and 0.522,respectively).Conclusions Lower sKL has the high CVD death rate and sKL level decreasing is an independent risk factor for CVD death in MHD patients.The lower sKL concentration in MHD patients with no or mild calcification may predict CVD mortality.This study suggests that sKL levels may be helpful in predicting the outcome of patients with MHD.

Objective To investigate the prevalence and cardiovascular risk factors of silent brain infarct (SBI) in Shunyi Cohort.Methods This study was based on the population based Shunyi Study in China.One thousand and twenty-seven stroke-free participants older than 35 years,who completed cerebral MRI,were included.Cardiovascular risk factors were assessed by interview,physical examination and blood sample tests.SBI was evaluated on 3D-T1WI,T2WI and FLAIR sequences.Associations between risk factors and SBI were analyzed by Logistic regression and adjusted for age,sex,and relevant confounders.Results One thousand and twenty-seven participants,aged (55.9 ± 9.4) years,37.7％ male,were assessed.One hundred sixty-four participants(16.0％) had SBI on MRI.The prevalence of SBI increased by age (every 10 years,OR=2.12,95％ CI 1.74-2.58,P＜0.01).Hypertension(OR =2.67,95％ CI 1.77-4.04,P＜0.01),diabetes(OR=2.48,95％ CI 1.64-3.76,P＜0.01) and smoking(OR=1.98,95％ CI 1.08-3.62,P =0.028) were significantly associated with SBI.Conclusions The prevalence of SBI in this Chinese population is 16.0％,which increases with age.Hypertension,diabetes and smoking are associated with SBI.

Objective To compare the efficacy and safety of leflunomide (LEF) combined with medium/low dose corticosteroids and full dose of corticosteroids in the treatment of IgA nephropathy. Method Primary IgAN patients diagnosed by renal biopsy with 18?65 years old and eGFR≥30 ml·min?1·(1.73 m2)?1 and proteinuria>0.5 g/24 h were enrolled in a prospective controlled clinical study. They were randomly divided into leflunomide combined with medium/low dose corticosteroids (LEF group) and corticosteroids alone (steroid group). The primary outcomes were (1) end stage renal disease or dialysis (2) 50% increase in serum creatinine above the baseline. Secondary outcome was the remission of proteinuria. Results Ninety patients completed the follow?up. The 24?hour proteinuria at baseline were 2.00(1.10, 2.88) g and 1.87(1.13 ,3.08) g in LEF group and steroid group respectively. Compared with baseline, it was significantly decreased in both groups at 6 months [0.30(0.11, 0.93) g, 0.30(0.14, 1.33) g] and 12 months [0.30(0.09, 0.82) g, 0.32(0.14, 0.66) g], (P<0.05). Estimated glomerular filtration rate (eGFR) at baseline, 6 months and 12 months were (80.39 ± 28.56), (87.12±28.70) and (88.20±30.26) ml·min-1·(1.73 m2)-1. It was decreased in steroid group (P<0.05), while no significant difference was detected in LEF group[baseline (87.63 ± 27.35), 6 months (86.91 ± 32.45), 12 months (90.06 ± 30.00) ml·min-1·(1.73 m2)-1, P>0.05]. At 6 and 12 months, there was no significant difference in terms of 24?hour proteinuria, serum creatinine and eGFR (CKD?EPI) between groups (P>0.05). There was no statistically significant difference in adverse events between groups during the treatment (9/40 cases in LEF group and 11/50 cases in steroid group, P>0.05). The average follow?up was 79 months, and there was no difference in the renal prognosis between the two groups. Multivariate Cox regression analysis revealed that serum creatinine at baseline and renal interstitial inflammatory cell infiltration predicted the risk of the progress of IgA nephropathy. Conclusion Leflunomide plus medium/low dose corticosteroids has a similar effect as full dose of corticosteroids in IgA nephropathy and does not increase the risk for adverse events during the treatment.

Objective To compare the complications and outcomes of urgent?start peritoneal dialysis (PD) and hemodialysis (HD) in end?stage renal disease (ESRD) patients, and explore the safety and effectiveness of PD which was as an urgent?start dialysis modality in ESRD patients. Methods All patients for urgent?start dialysis, who initiated dialysis without a long?term dialysis access or had the long?term dialysis access under 30 days in Renji Hospital from January 1st 2013 to December 31st 2014, were enrolled. According to the dialysis modalities, patients were divided into PD group and HD group. Participants were followed up until death, transferred to other centers, lost of follow up or January 1st 2016. Dialysis?related complications within 30 days of implantation, complications of reimplantation and the occurrence of bacteremia between two groups were compared, and their survival rates were tested by Kaplan?Meier curves. Results Among 178 patients in this study, there were 96 (53.9%) patients in PD group and 82 (46.1%) patients in HD group. Compared with those of HD group, patients of PD group presented more cardiovascular disease [21(21.9%) vs 8(9.8%), P=0.029], higher serum potassium [(4.5±0.8) mmol/L vs (4.3±0.8) mmol/L, P=0.038], but less heart failure (NYHA Ⅲ?Ⅳ) [26(30.2%) vs 40 (48.8%), P=0.014], lower brain natriuretic peptide (BNP) [328.5 (129.5, 776.8) ng/L vs 503.5(206.0, 1430.0) ng/L, P=0.008], higher hemoglobin [(81.5 ± 17.7) g/L vs (75.3 ± 22.5) g/L, P=0.039], higher serum albumin (33.5±5.7) g/L vs (31.3±6.7) g/L, P=0.022] and higher serum pre?albumin (304.5±78.0) mg/L vs (257.0 ± 86.1) mg/L, P<0.001]. PD group presented less dialysis?related complications [5 (5.2%) vs 20(24.4%), P<0.001], less dialysis?related complications requiring reimplantation [1(1.0%) vs 20(24.4%), P<0.001] and less bacteraemia [3(3.1%) vs 11(13.4%), P=0.011]. The 3?, 6?and 12?month patient survival rates of PD and HD group were 97.9% vs 98.4%, 97.9% vs 98.4%, and 92.1%vs 93.0% respectively, and no significant difference was found (Log ? rank=0.004, P=0.947). Conclusions Patients with urgent?start PD have less complications within 30 days of implantation and occurrence of bacteremia than patients with urgent?start HD, and the same survival rates. PD may be a feasible and safe urgent?start dialysis modality for ESRD patients.
