Methods Fourteen cases of thumb deformities were detected preoperatively by X-ray plain film, angiography and ultrasound examination. The deformities of bone, hemokinesis of thumbs and its blood supply were analysed. The results were compared with their pathological changes during the operation. The deformity was corrected by operations of bone resection, reconstruction of tendon insertion site and preservation of main arteries. Results There were bone deformities 13 cases, abnormal or absent tendon insertion of the main thumb 14 cases. The nutrient of the deformity thumb was supplied by main trunk artery in 11 cases. Conclusion Angiography and ultrasonic examination play an important role in the diagnosis of thumb syndactyly. It can help determine appropriate surgical procedure so that secondary deformities can be prevented after operation. 3 refs,5 figs.展开更多

This kind of detector belongs to non-automatic weighing instrument, and certain problems will inevitably occur in the actual use process. At present, with the continuous improvement of social economy in our country, the production and ownership of automobiles are in the process of rapid development, and the safety performance of automobiles has also received increasing attention. However, the actual inspection of the axle wheel weight gauge is mainly to check whether the braking force of the motor vehicle can meet the corresponding standard, which plays a very important role in ensuring the safety performance of the whole vehicle. In recent years, relevant motor vehicle safety inspection agencies have used various inspection standards, from the initial GB 21861-2014, GB 7258-2017 safety inspection standard and GB 18565-2016 comprehensive inspection standard to the current revision of GB 3847-2018 and GB 18285-2018 environmental inspection standards. With the continuous revision of comprehensive inspection standards, the demand for talents of relevant motor vehicle safety inspection agencies is getting higher and higher. Only when the comprehensive ability of relevant staff is continuously improved, can they better deal with the inaccurate and unreliable inspection results of motor vehicle safety inspection agencies. Based on this, this paper studies the evaluation of measurement uncertainty of indication value of special axle (wheel) gravimeter for motor vehicle testing, for reference.展开更多
