Motion segment and extraction from continuous signals is the premise of surface electromyography (sEMG) analysis. For the problem that sEMG energy threshold required repeated manual testing to set, this the paper established a this mathematical model of continuous actions based on Gaussian sEMG energy curve, in which the energy threshold was set according to the distribution of Gaussian signal section, and differentiated the action signals from no-action signals combined with energy comparison method. The experiment results showed the method can achieve continuous repetitive action segmentation, and compared with manual segmentation of the same signal, has a higher degree of coincidence.

Background and purpose:Progranulin (PGRN) is a novel growth factor that plays an important role in the tumorigenicity, tumor cell migration and cell cycle. Its expression in many malignant tumor cells is high. It is not only involved in tumor cell growth, but also closely related with the occurrence and evolution of tumor. This study was to investigate the expression of PGRN in gastric cancer and the effects on proliferation and senescence in gastric cancer cell line BGC823. Methods:Immunohistochemical method was used to detect the expression of PGRN in gastric cancer tissues and adjacent normal tissues; Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of PGRN in PGRN-siRNA BGC823 cells;MTT method, cell colony formation and cell senescence experiments were used to explore the effects of PGRN on proliferation and senescence in BGC823 cell. Results:PGRN protein levels were high in gastric cancer tissues;Knocking down the PGRN gene in BGC823 decreased the proliferation and clonogenic capacity, cloning efifciency in PGRN-siRNA group was (25.3±3.1)%, in the control group was (72.1±5.7)%, and in the normal cells was (80.3±4.0)%, there was no signiifcant difference between normal group and control group, but there were signiifcant differences among PGRN-siRNA group and the other two groups (P<0.05);Knocking down the PGRN gene in BGC823 cells could promote cell senescence. The positive rate of aging in PGRN-siRNA group was (27.6±2.1)%, in the control group was (3.2±1.3)%, and in the normal group was (1.9±1.2)%, there was no signiifcant difference between normal group and control group. But there were signiifcant differences among PGRN-siRNA group and the other two groups (P<0.05). Conclusion:PGRN can be used as a new marker for gastric cancer, and provide new ideas to the treatment of gastric cancer.

Guided by the emphasis on learning process, the educational reform has designed a "trinity" comprehensive evaluation system (quantitative clinical practice, in-class medical record analysis, and staged comprehensive written test) as the formative evaluation of the course. Through this assessment system, students' self-learning potential is stimulated, clinical skills practice is strengthened, and "taking exams to promote learning and taking exams to promote teaching" is realized. In the practice of teaching reform, it has been found that compared with the conventional teaching class, the students in the teaching reform class have higher participation and are more satisfied with the process assessment of the "trinity" comprehensive evaluation system.
