The first step of bacilli culture is inoculation bacteria on culture medium. Designing a device to increase efficiency of inoculation is significative. The new device is controlled by SCM. The stepper motor can drive the culture medium rotating, accelerating, decelerating, overturn and suspending. The device is high practicability and efficient, let inoculation easy for operator.

According to the circumstance of hospital equipment maintenance, we designed a computer program for management of hospital equipment maintenance process by Java programming language. This program can control the maintenance process, increase the efficiency; and be able to fix the equipment location.

According to the biomedical signal characteristics, a new biomedical signal processing toolkit is developed. The toolkit is programmed by Java. It is used in basic digital signal processing, random signal processing and etc. All the methods in toolkit has been tested, the program is robust. The feature of the toolkit is detailed explained, easy use and good practicability.

According to the development of body temperature measurement mode, an ear thermometer with infrared thermopiles sensor is designed for body thermometry. Compared with oral thermometer, the accuracy of ear thermometer is acceptable.

Objective:To investigate the dose-response relationship between physical activity and sarcopenia in middle-aged and elderly people in Urumqi, and then provide the reference to guide the middle-aged and elderly people to arrange exercise reasonably.Methods:A total of 1886 middle-aged and elderly people (aged ≥ 50 years old) from December 2018 to December 2019 in Cihui Health Management Center in Urumqi were selected as the research objects to conduct a questionnaire survey, collected general information and physical examination data, and used the International Physical activity questionnaire to investigate and evaluate their daily activities. Diagnostic criteria of the Asian Working Group on Sarcopenia (AWGS) 2019 were used. Logistic regression model was used to analyze the relationship between physical activity and sarcopenia, and restricted cubic spline was used to analyze the dose-response relationship between physical activity and sarcopenia.Results:Among the investigated subjects, 208 people suffered from sarcopenia, and the prevalence rate was 11%. Multivariate analysis showed that after adjusting for confounding factors such as demographic characteristics, moderate and high intensity physical activity was associated with a lower risk of sarcopenia compared with low intensity physical activity ( OR = 0.389, 95% CI 0.261-0.580; OR = 0.055, 95% CI 0.025-0.122). The dose-response relationship between physical activity and sarcopenia showed an approximate 1-shaped dose-response relationship between total physical activity and sarcopenia ( P<0.01). Conclusions:The strength of the association between physical activity and sarcopenia was approximately an "L" shaped curve, and increased physical activity was associated with a lower risk of sarcopenia when physical activity was between 2500 and 3500 MEt-min/week.
