Clinical effect of 3D-guided percutaneous hollow screw fixation for patients with Herbert Ⅰb-type scaphoid fractures / 局解手术学杂志

Objective To investigate the clinical value of individual design combined with 3D-guided percutaneous hollow screw fixation for patients with Herbert Ⅰb-type scaphoid fractures.Methods Totally 93 cases of Herbert Ⅰb-type scaphoid fractures patients who were admitted into our hospital from November 2015 to April 2017 were divided into the external fixation group(31 cases),the internal fixation group(29 cases)and the minimal invasion group(33 cases).The external fixation group was treated with cast immobilization;the internal fixation group was treated with open reduction and internal fixation;the minimal invasion group was treated with individual design combined with 3D-guided percutaneous hollow screw fixation.The time of bone union,return-to-work time,rateof bone union,wrist range of motion (ROM)and Mayo function score of the three groups were compared.Results The time of bone union,return-to-work time and wrist range of motion in the minimal invasion group were(6.7 ±0.9)weeks,(7.3 ±0.9)weeks and(103.8 ±5.9)°respectively,which were better than the other two groups with statistically significant difference(P<0.05).The bone union rate of the external fixation group,the internal fixation group,and the minimal invasion group were 83%,86.2%and 100%respectively.The difference between the minimal invasion group and the other two groups were statistically significant(P<0.05).The Mayo function score of the external fixation group,the internal fixation group, and the minimal invasion group were 71.0%,82.8% and 97.0% respectively.The difference between the minimal invasion group and the other two groups were statistically significant(P<0.05).Conclusion Individual design combined with 3D-guided percutaneous hollow screw fixation treatment has exact effect for Herbert Ⅰb-type scaphoid fractures with fast recovery,and it's worthy of wildly use.

Differences between clinical and imaging standardized resident training method in ultrasound department / 中华医学教育探索杂志

The standardized resident training is an important and necessary way to cultivate high-quality medical talents.The goals between clinical and imaging residents in standardized training of ultrasound department are different.For clinical residents,the purpose is to understand the ultrasound images of various common diseases,combine clinical manifestation with ultrasound images,and improve the level of clinical diagnosis and treatment.For imaging residents,the goal is much higher and stricter;they need to master solid ultrasonic knowledge,independent operational and diagnostic ability,in order to provide reliable and accurate ultrasonic diagnosis.We individually design the teaching plan and methods in ultrasound department,in order to improve teaching efficiency and quality.

Construction of a Universal Assessment Support System for Augmentative and Alternative Communication Individual Design / 中国康复理论与实践

@# The augmentative and alternative communication (AAC) assessment items wwere formed referencing the items of the assessment approach of foreign countries and the successful cases and relating the realities of our country. Then, the method that setting out the capability item of AAC and assessing the ability of the individual with disability according to the item and going back to the capability item and presenting the redesign advices were adopted. Finally, a universal support assessment system for AAC individual design was constructed, which could support the assessment of AAC to help the special education teachers in our country.
