Objective To investigate the effect of play therapy on childhood autism.Methods A child with autism treated with play therapy was reported.Results and Conclusion The play therapy is helpful to improve the social skill of the children with autism.

Objective To study the auditory processing abilities of children with learning difficulty and deter-mine the proportion of the children with auditory processing disorder.Methods A single factor completely random-ized experimental design was used.Seventeen children with learning difficulties and 31 normal children from grade 2 to grade 4 in Beijing were induded in this study.The abilities of low-pass filtered speech,competing sentences,di-chotic digits and frequency patterns were tested through auditory processing disorder screening test software.Results There were significant differences in the abilities of listening sentences and digits in competitive environment and recognizing frequency patterns between children with learning difficulty and without.The auditory processing ability of children with learning difficulties was obviously poorer than normal children.The incidence of auditory processing disorder among the children with learning difficulties was 41.176%~58.824%.Conclusion The auditory process-ing ability in the competitive environment of children with learning difficulties was obviously poorer and they need in-tervention specifically.

Objective To investigate the preventive effect of continuous quality improvement(CQI) on malnutrition,inflammation,peritoneal dialysis adequacy and cardiovascular events in elderly patients undergoing peritoneal dialysis.Methods A single-center prospective self-controlled study was performed.32 stable elderly patients to undergo continuous ambulatory peritoneal dialysis (CAPD) were included.The continuous quality improvement program was conducted by using the 4-step problem-solving framework called the PDCA cycle (plan,do,check and act).The dialysis adequacy,nutritional status,inflammation and cardiovascular events were analyzed before and after PDCA.Results Compared with before PDCA,the proportion of patients with Kt/V≥1.7 and urea kinetics (Kt/V) level were increased after PDCA [71.8％ vs.93.75％,(1.97±0.36) vs.(2.08±0.33),both P＜ 0.05].Serum levels of albumin (ALB),prealbumin (PAB) and serum carbon dioxide combining power (CO2 CP) were increased after PDCA (all P＜0.05).The proportion of patients with ALB≥40 g/L was increased after PDCA as compared with before PDCA (9.4％ vs.31.3％,P＜0.05).The nutritional variables including mid-arm circumference (MAC),triceps skinfold thickness (TSF),mid arm muscle circumference (MAMC),and lean body mass (LBM),lean body mass percentage (LBM％),normalized protein equivalent of total nitrogen appearance (nPNA),handgrip strength were improved after PDCA (P＜ 0.05).High sensitivity C-reactive protein (hs-CRP) level and the proportion of patients with hs-CRP＞3 mg/L were decreased after PDCA as compared with before PDCA [(8.65±6.22) mg/L vs.(5.37±4.33) mg/L,53.1％ vs.25％,both P＜0.05].The incidence of peritoneal dialysis related peritonitis was reduced obviously from 1 case every 25.4 months to 1 case every 78.1 months after PDCA (P ＜ 0.05).The hospitalization rate due to cardiovascular events was decreased after PDCA as compared with before PDCA (25％ vs.3.13％,P＜0.05).Conclusions CQI may significantly improve the malnutrition,inflammation and dialysis adequacy,and reduce the hospitalization rate due to cardiovascular events in elderly patients undergoing peritoneal dialysis.

Objective To examine the clinical characteristics and red cell distribution width (RDW) changes and to investigate the prognostic value of RDW in elderly patients undergoing peritoneal dialysis(PD). Methods We retrospectively analyzed the data of 59 elderly patients aged 60 or over who had undergone regular PD for over three months at Beijing Hospital from July 1 ,2005 to June 30 ,2017.All patients were followed up until the occurrence of a composite event or until December 31 ,2017. General characteristics ,baseline laboratory data ,RDW at baseline ,and time-average RDW during the follow-up were compared between the non-survival group and the survival group.Cox regression analysis was performed to determine whether RDW was an independent risk factor of all-cause mortality. Results Fifty-nine elderly PD patients with a mean age of (70.5 ± 6.6) years were included.The median follow-up duration was 40(25 ,56)months and the median survival duration was 57(36.6 ,74.4)months. The 1-,3-,and 5-year survival rates of all patients were 98.3%(n＝58) ,72.9%(n＝ 43) ,and 52.5%(n＝ 31) ,respectively.Twenty-eight patients died during the follow-up ,of whom 15 died of infection ,8 of cardio-cerebrovascular disease and 5 of other causes.Non-survivors had higher Charlson Comorbidity Index (CCI)scores ,higher levels of RDW at baseline ,higher time-average RDW ,lower initial total KT/V ,and lower initial total CCr (all P＜0.01).In univariate analysis ,high CCI ,high basic RDW ,high time-average RDW ,low serum albumin ,low serum ferrum , and low serum cholesterol were associated with all-cause mortality (all P＜ 0.05).In multivariate- adjusted Cox analysis ,high CCI(HR＝1.679 ,95% CI :1.238-2.236 ,P＝0.001)and high time-average RDW(HR ＝ 1.889 ,95% CI :1.195-2.987 ,P ＝ 0.007)were independent predictors for all-cause mortality in elderly PD patients. Conclusions Time-average RDW may independently predict the mortality of elderly PD patients. The prognostic value of dynamic RDW may be similar to that of CCI.
