Objective:To understand the psychological status and nursing needs of maintenance hemodialysis (MHD) patients and provide reference for clinical targeted nursing.Methods:Using the phenomenological research method, a total of 15 patients with MHD in the First Affiliated Hospital of Zhengzhou University were selected as the research objects by the purposive sampling method, and they were given semi-structured individualized interviews. The Colaizzi 7-step analysis method was used to organize the data, extract the inductive themes and analyze the results.Results:The psychological status of MHD patients was repressed fear, despair and helplessness and acceptance. The nursing needs of MHD patients included disease-related knowledge needs, social support needs and health guidance needs.Conclusions:MHD patients have negative psychology. Medical staff need to understand the psychological status and nursing needs of patients and formulate targeted nursing interventions to meet the actual needs of patients and improve the quality of life of them.

Objective:To explore the effect of family-participated dietary management on dietary compliance behavior and nutritional status in elderly maintenance hemodialysis (MHD) patients.Methods:From July 2019 to December 2020, a total of 120 elderly MHD patients admitted in the First Affiliated Hospital of Zhengzhou University were selected as the research objects, and divided into the experimental group and the control group with 60 cases in each group by random number table method. The control group conducted routine dietary management, and the experimental group received dietary management based on family participation. Six months after intervention, the dietary compliance attitude, dietary compliance behavior and nutritional status were compared between the two groups.Results:Six months after intervention, the scores of social restriction attitude, self-care attitude, acceptance attitude and dietary compliance behavior attitude of the experimental group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . The scores of fluid restriction behavior, potassium intake behavior, self-care compliance, compliance in the face of difficulties, and dietary compliance of the experimental group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . The serum prealbumin (PA) , albumin (ALB) , hemoglobin (Hb) , and transferrin (TRF) of the experimental group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Diet management based on family participation can enhance the attitude of dietary compliance, promote the development of dietary compliance behavior, and improve the nutritional status of elderly patients with MHD.

Objective To study the pre-and post-surgical orthodontic treatment methods of patients with skeletal malocclusion treated through combined orthodontic-orthognathic surgery,and to set some guidance for the future clinical Work.Methods Twenty-five skeletal malocclusion patients in our clinic aged from 17 to 36 were treated by presurgical orthodontic treatment,orthognathic surgery and postsurgical ortho dontic treatment.Presurgical orthodontic treatment included alignment of dental arches,leveling of arches,elimination of rotations,coordination of the arches,and decompensation of anterior and posterior teeth.The postsurgical orthodontic treatment included closing residual spacing,final tooth alignment,maximum interdigitation,finalizing torque,artistic positioning,ideal overjet/overbite relationship and establishment of correct root parallelism.Results The duration of presurgical orthodontic treatment was 14.41 months on average(2～23 months),and the postsurgical orthodontic treatment time was 6.94 months on average(1.5～13.5 months).The duration for the whole active treatment was 21.35 months on average(7～35 months).The maxilla was moved back on an average 5.00 mm in maxillary protrusion cases.The mandible was moved anteriorly on an average 7.25 mm in mandibular retrusion cases.The mandible was moved back on an average 6.55 mm in mandibular protrusion cases.The chin was moved anteriorly on an average 5.33 nan in retrusion of chin cases.Conclusions Pre-and post-surgical orthodontic treatments are important procedures to the surgical treatment for skeletal malocclusion and basic needs to obtain successful treatment results.
