Objective To investigate the correlation between fatigue and coping strategies among peritoneal dialysis patients,to improve their health consciousness and reduce the fatigue.Methods A total 107 patients were surveyed with general data questionnaire,Multidimensional Fatigue Symptom Inventory-Short Form( MFSI-SF) ,and Medical Coping Modes Questionnaire,MCMQ.Results The score of fatigue was (83.32 ±1.54) points,which indicated the fatigue remained in high level.Scores from high to low were dialysis≥5years,dialysis<1year and 1year≤dialysis<5years.Patients mainly took the coping style with positive face.Pearson correlation analysis showed that fatigue was negatively correlated withface(r=-0.300,P<0.05),while it was positively correlated with withdrawand yield(r=0.227,0.300,all P<0.05).Conclusion Patiens should be encouraged to actively face the disease,pay more attention to their own state of dialysis and improve the effect of drain,reduce fatigue,then to reply for both mind and body health.

Objective:To explore the application of peritoneal dialysis routine examination in reducing the incidence of peritonitis associated with peritoneal dialysis.Methods:From July 2018 to June 2019, 191 patients with peritoneal dialysis who were followed up regularly in the nephrology department were selected as the study subjects.Using convenient sampling method, outpatient follow-up on Tuesday were selected as control group(95 cases) and fixed outpatient follow-up on Thursday were selected as observation group(96 cases). Routine follow-up was performed in the control group, and routine examination of peritonitis was performed in the observation group during the follow-up.Intervention was given immediately when the problems were found to the naked eye and the examination results were abnormal.The incidence of peritonitis in the two groups was compared.Results:Peritonitis occurred in 24 cases in the control group(25.26%), and 9 cases in the observation group(9.38%). The incidence of peritonitis in the observation group was lower than that in the control group, and the difference was statistically significant(χ 2=5.972, P<0.05). Conclusion:The occurrence of peritoneal dialysis-related peritonitis is related to a variety of factors.Paying attention to the routine examination of peritonitis and observing the color of peritonitis, strengthening the aseptic fluid exchange operation, and following up the patients can effectively reduce the occurrence of peritonitis and improve the quality of dialysis.

Objective: To compare the diagnostic value of T2 weighted imaging (T2WI), diffusion-weighted imaging (DWI), and T2WI+ DWI magnetic resonance imaging (MRI) for staging of rectal cancers for improving the accuracy of tumor staging. Methods: From January 2011 to December 2013, 120 cases of rectal cancers proved by colonoscopy without receiving any anti-tumor treatment were enrolled retrospectively. The MRI data for these patients were divided into three groups, ie., T2WI, DWI and T2WI+ DWI, for evaluating the tumor stages. The results were compared with histopathologic findings. The sensitivity and specificity were calculated and compared with chi-square test. The nodal staging was predicted by using T2WI+ DWI. Results: The accuracy for prediction of tumor staging was 83.3%, 65.0% and 92.5% for T2WI, DWI, and T2WI+ DWI respectively. The specificity for evaluating T1 and T2 stage, and the sensitivity for evaluating T3 by DWI was significantly lower than those using T2WI and T2WI+ DWI in rectal cancers. The sensitivity for evaluation of T2 by DWI was lower than that using T2WI+ DWI (63.0% vs. 88.9%). The sensitivity for evaluation T2 and specificity for T3 by T2WI+ DWI was higher than thouse using T2WI only (88.9% vs. 51.9%, 94.0% vs. 72.0%). The accuracy for prediction of nodal staging by using T2WI+ DWI was 62.1% (72/116). Conclusions T2WI is the key sequence for staging of rectal cancers. Although the diagnostic accuracy was not good by using DWI alone, the combination of T2WI and DWI can improve the accuracy significantly for tumor staging in rectal cancers, whereas the nodal staging was still a hard task for radiologists.
