We compared the clinical effects of minimally invasive percutaneous pedicle screws osteosynthesis (MIPPSO) and open surgery on the repair of thoracolumbar vertebra fracture. Seventy patients, who suffered from thoracolumbar vertebra fracture and received treatment at our hospital, were selected and randomly divided into either the minimally invasive percutaneous pedicle screws osteosynthesis group (MIPPSO group) and the traditional open pedicle screws osteosynthesis group (TOPSO group) with 35 cases in each group. The perioperative parameters including length of incision, duration of operation, bleeding during operation, length of hospital stay, the changes of pre-operative and post-operative VAS pain scores, inflammatory indexes including serum C-reactive protein (CRP) and creatine kinase (CK), and imaging indexes including Cobb's angle and anterior margin height of vertebral body of both groups were compared. The length of incision, duration of operation, bleeding volume during operation and length of hospital stay in the MIPPSO group were significantly lower than those in the TOPSO group (P<0.05). Both minimally invasive surgery and traditional surgery effectively alleviated the pain (P<0.05), which was more significant in MIPPSO group (P<0.05). The post-operative inflammatory indexes, CRP and CK levels, of both groups were higher compared to the pre-operation (P<0.05), which was more significant in TOPSO group (P<0.05). The differences of imaging indexes, including Cobb's angle and anterior margin height of injured vertebra, were statistically significant between pre-operation and post-operation for each group (P<0.05); however, there were no statistically significant differences between two groups at either pre-operation or post-operation (P>0.05). The effect of minimally invasive percutaneous pedicle screws osteosynthesis is similar to the traditional open surgery, however, the MIPPSO technique has the advantages of small trauma, less bleeding, short duration of operation, rapid post-operative recovery, light pain, less economic cost, and better aesthetic effect and is therefore worthy of clinical promotion.

In 2018, the scale of China's digital economy has reached up to 31.3 trillion, accounting for 4.8% of China's GDP. In the fourteenth five-year plan, the concept of "Digital China" was clearly put forward again. And the digital economy has been developing rapidly. Starting from the background of industrial interconnection, relying on the preconditions of big data center construction project in Jilin Province, comparing with the development status and trends at home and abroad, this paper combs out the existing problems of traditional financial process in data collection, specification, utility and use, and proposes to start from the integration of business and financial process, build standardized sharing process, and finally, with the help of OCR, RPA and AIIt also analyze the specific application scenarios of the platform in different fields of universities, large enterprises and institutions, financial accounting and consulting enterprises and the government.
