Objective To examine the effectiveness of cognitive therapy on orthodontic patients with body image disturbance (BID).Methods 21 orthodontic patients with BID in study group re ceived routine orthopedic treatment and cognitive therapy,and 15 orthodontic patients with BID in control group received only routine orthopedic treatment.All patients were tested with Symptom Checklist 90 (SCL-90),Cognitive Bias Questionnaire (CBQ),Self-Rating Depression Scale (SDS),Self-Rating Anxiety Scale (SAS),and Body Image Questionnaire (BIQ) at prior and post treatment.Results SAS and SDS scores in the study group were decreased after treatment,and SDS decrease in the study group was larger than that in control group.The factor scores of both groups on the SCL- 90were decreased after treatment,and most factor scores decrease in study group was larger than that in control group.Three dimensions (except for function impairment) of the BIQ were improved in the study group as compared with control group.Cognitive styles were improved on the study group as compared with control group.Conclusions The cognitive therapy can improve cognitive bias and mental health of patients with BID.

The rapid development of point-of-care testing (POCT) in clinical laboratories has brought challenges to the unified management in the hospital. There are many problems, such as how to ensure the ability and qualification of POCT operators, how to improve the quality management awareness of human, machines, materials, methods and environment in the process of POCT in clinical laboratories, how to help the clinical laboratories in the hospital to carry out POCT comparison, and how to strengthen the information construction of POCT in the hospital. Thus, this article reviews the practice and experience of POCT management in our hospital on POCT quality assurance and the problems existing in POCT in clinical departments, proposes suggestions and solutions to strengthen the unified management of POCT in clinical laboratories and establish POCT quality management documents and to improve quality awareness. We hope to provide references for hospital administrators, medical departments, nursing departments, quality control departments and other functional departments on the quality management of POCT in the hospital, and find helpful answers to the puzzles of clinical laboratory in POCT, so as to make joint efforts to standardize the quality management of POCT in the hospital to ensure the accuracy of testing results.
