Objective To analyze and discuss the clinical characteristics and prognostic risk factors of 80 patients with tetanus in our hospital, and to provide a basis for tetanus in clinical diagnosis and treatment, early identification of risk factors and reduction of mortality. Methods The clinical case data of 80 tetanus patients were collected from our hospital from January 2013 to December 2020. A database of 20 factors that may affect the prognosis of tetanus was established, its clinical characteristics were summarized, and its prognostic risk factors were analyzed. Results Among the 80 patients, the main clinical manifestations were closed teeth (97.5%), dysphagia (92.5%), spasms and convulsions of extremities (77.5%), and the common complications were respiratory failure (32.5%) and myocardial damage (30%). The following 8 factors: ICU patients, mechanical ventilation, fever, concurrent respiratory failure, limb spasm and convulsions, Apache II score, Ablett classification, length of hospitalization, the difference between the death group and the survival group was statistically significant (P < 0.05). The logistic regression analysis suggested that Hospital stay, mechanical ventilation and Ablett classification were risk factors for prognosis of tetanus (P < 0.05). Conclusions The awareness of tetanus for manual workers should be strengthened. Complete debridement early after trauma and timely artificial immunization are the key measures to prevent tetanus; If patients with tetanus have long hospitalization time, mechanical ventilation and high Ablett grade, clinical management should be strengthened.

Rotation, scaling, translation (RST) and boundary micro deformation are the main factors that affect the matching results of vector graphics, and are also good criteria for evaluating shape description algorithms. In this paper, a vector graphics matching algorithm using multi-dimensional object segmentation ratio is proposed for the influencing factors of shape matching. This algorithm extracts shape characteristic by constructing feature lines for vector graphics. It can accurately describe the shape characteristic of the polygon features to measure the shape similarity between the graphics. The vector graphics of 2 000 real geographical entities are used as the standard library for matching experiment, and half of the graphics are randomly selected as matching graphics. The matching graphics are taken to RST transformation and boundary simplification operations with varying degrees. The transformed graphics are matched with the standard library. The matching results are compared with other vector graphics matching algorithms to test the shape retrieval effect of this algorithm. This experiment demonstrate that the proposed algorithm has higher matching accuracy, RST invariance and deformation robustness. Therefore, it can accurately identify the shape of vector graphics.

In order to analyze and solve the jitter issue found in the motion process of a new type six-axis robot, eliminate the influence of the robot terminal jitter and improve the accuracy of the robot, this paper proposed a new testing scheme for the jitter analysis of the six-axis robot moving along a path by using the real working condition, excitation-body-receiver vibration transfer model, and experimental testing methods. By combining the vibration test, uniaxial work vibration test and natural frequency test of the robot body, the scheme can effectively analyze the impact of the robot trajectory on the terminal jitter phenomenon.

Aiming at the training needs of railway signal and control profession under the background of new engineering, guaranteed by the construction of practice platform and system, this paper puts forward the concept of "standardized guidance to promote connotation development, practice strengthen to expand extension demand" and constructs railway scene practical teaching system of "scene -inquiry-reflection-innovation". With multiple forms of teaching, diversified training and multi-channel practice, this paper forms an open Internet + engineering practice teaching mode. The implementation of this mode strengthens the interdisciplinary integration, stimulates the enthusiasm of students' independent learning, and improves students' innovative ability in engineering practice.
