Objective To explore the effect of relaxation training with listening to music on negative emotions of hemodialysis patients.Methods 70 hemodialysis patients were divided into the intervention group and the control group by random number table,and each group had 35 cases.The control group was given routine care,health education and routine discharge guidance during dialysis by the responsible nurses.The intervention group had relaxation training with listening to music on the basis of routine care.Before the intervention and three months after the intervention the Hamilton Rating Scale for Depression was used as an assessment tool to evaluate negative emotion of patients.Results Before intervention,the HAMD scores of the two groups showed no significant differences.3 months after intervention,HAMD scores had significant difference between two groups.Conclusions Relaxation training with listening to music can significantly improve patients' negative emotions,and is worthy of clinical application.

Objective To compare the effects of selenium nanoparticles (Nano-Se) and sodium selenium (Na2SeO3) on apoptosis and reactive oxygen species (ROS) of articular chondrocytes from patients with Kashin-Beck Disease (KBD) in vitro,and provide a scientific basis for preventing KBD.Methods The subjects with KBD were diagnosed on National Clinical Diagnostic Criteria of KBD (WS/T207-2010),articular cartilage from 8 patients undertaken joint replacement operation were collected.In vitro,chondrocytes were treated with concentration of 0,25,50,100,200,300,400 and 500 μg/L of Nano-Se and Na2SeO3 for 5 d,respectively.Cell growth was detected by MTT assay,and the highest concentration and time corresponding to the highest survival rate of Nano-Se and Na2SeO3 were used in the following experiment.KBD chondrocytes were treated with Nano-Se and Na2SeO3,and divided into control group,Na2SeO3 group,Nano-Se group according to the randomized design.Each group had 8 cases.The cell apoptosis and ROS were detected by flow cytometry.Results The optimal intervention concentration of Nano-Se and Na2SeO3 was 100 and 400 μg/L,respectively.The optimal intervention time of NanoSe and Na2SeO3 both was 3 days.There was a significant decrease in the total and terminal apoptosis,ROS level of chondrocytes in Nano-Se group [(4.67 ± 0.89)％,(1.51 ± 0.48)％,(56.04 ± 4.81)％] and Na2SeO3 group [(7.07 ±0.25)％,(4.37 ± 0.37)％,(87.13 ± 6.60)％] compared with those of control group [(9.95 ± 0.38)％,(6.93 ± 0.42)％,(125.17 ± 16.60)％,all P ＜ 0.01].The difference of early apoptotic rate among control group,Na2SeO3 group,NanoSe group [(3.02 ± 0.41)％,(2.7 ± 0.46)％,(3.16 ± 0.56)％] was not statistically significant (F =2.11,P =0.35).Conclusion Appropriate concentration of Nano-Se can significantly decrease oxidative stress of KBD chondrocytes and inhibit apoptosis compared to Na2SeO3.

Objective To compare the influence of hemodialysis (HD) and peritoneal dialysis (PD) on early outcome of patients underwent kidney transplantation from donation after cardiac death (DCD).Methods Patients admitted in the First People's Hospital of Foshan with DCD kidney transplant from January 1st,2011 to June 30th,2016 were analyzed retrospectively.Recipients were grouped into HD group (n=61) and PD group (n=28) according to their pre-transplant dialysis modality.Their short-term outcomes after DCD kidney transplant were compared,including recovery of renal function,short-term complications and laboratory data.Results Patients had longer dialysis duration and lower hemoglobin,serum albumin and phosphorus in PD group than those in HD group (all P ＜ 0.05),but no significant difference shown in age,gender,body mass index,primary disease,blood pressure,and hepatitis B infection (all P ＞ 0.05).HD patients with 6.00(4.00,11.00) d recovery time of renal function,18.00(17.00,21.50) d hospital time,had 24.59％ the delayed graft function (DGF),3.28％ acute rejection and 16.39％ infection during hospitalization.While for PD patients the recovery time of renal function was 4.00(3.75,7.00) d;hospital time was 19.00(15.00,21.75) d;the incidence rate of DGF was 14.29％;acute rejection was 3.57％;and infection during hospitalization reached 17.86％.Above indexes were not significantly different between HD and PD groups (all P ＞0.05).Repeated measure ments showed that,compared with those before transplant surgery,after 1 month,3 months and 6 months HD and PD groups had decreased creatinine and phosphorus,and increased hemoglobinserum albumin and calcium;Serum albumin and calcium were different between the two groups (P ＜ 0.001,P=0.040),whereas creatinine,hemoglobin and phosphorus did not show difference (all P ＜ 0.05).After transplantation the trends of creatinine,hemoglobin,calcium and phosphorus were not different between the two groups (P values were 0.295,0.310,0.501 and 0.063,respectively).Conclusions No significant difference of the recovery regarding renal function,anemia,nutrition status and mineral metabolites was found between pre-transplant HD and PD modality in patients who underwent DCD kidney transplantations.
