ABSTRACT
Objective:To explore the prevalence and risk factors of thyroid diseases in the physical examination population of Hohhot.Methods:From July 2017 to July 2018, 3 100 health examinees from Inner Mongolia National Examination Medical Center were selected as subjects for questionnaire survey, thyroid function test and thyroid ultrasound examination; a multinomial logistic regression model was used to analyze the relationship between relevant investigation factors and different types of thyroid diseases (simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules).Results:Among the 3 100 healthy examinees, there were 2 885 effective responders, including 743 males and 2 142 females, aged (46.23 ± 12.32) years; the simple thyroid nodules, simple thyroid dysfunction, and thyroid dysfunction with nodules were 909, 648, and 619 cases, respectively, and the detection rates were 31.51%, 22.46%, and 21.46%, respectively. Logistic regression analysis results showed that age [35 - 54 years old: odds ratio ( OR) = 1.30, 95% confidence interval ( CI): 1.01 - 1.68; ≥55 years old: OR = 2.30, 95% CI: 1.68 - 3.14, P < 0.05], gender ( OR = 1.65, 95% CI: 1.32 - 2.07, P < 0.05), obesity ( OR = 1.35, 95% CI: 1.08 - 1.70, P < 0.05), and mental stress [significant: OR = 1.64, 95% CI: 1.09 - 2.48; some: OR = 1.54, 95% CI: 1.02 - 2.32, P < 0.05] were the risk factors affecting the occurrence of simple thyroid nodules. The age (35 ~ 54, ≥55 years old), gender, bad mood (a little), and mental stress (significant) were risk factors that affected the occurrence of simple thyroid dysfunction; eating high iodine food was its protective factor. The age (35 ~ 54, ≥55 years old), gender, obesity, and thyroid family genetic history were risk factors for thyroid dysfunction with nodules; the consumption of iodized salt was its protective factor. Conclusions:Older women are high-risk groups for thyroid diseases. Obesity, bad mood, mental stress will increase the risk of the disease. Daily consumption of iodized salt and moderate consumption of high iodine food can reduce the risk of the disease.
ABSTRACT
Computing thinking is one of the hotspots in computer education field,computer network is the core course of computer,and social information process is increasing the need of computer network professionals.The characteristics of computer network course,teaching of computer network course and problems related with teaching of computer network course were analyzed in aspects of its teaching contents,teaching methods and examination methods in order to train more excellent applied professionals of computer network and improve the computing thinking of undergraduates.The ways or methods for training the computing thinking of undergraduates were put forward,which can thus provide new ideas for the teaching reform of computer network course in colleges and universities.
ABSTRACT
The National Natural Science Foundation-supported papers in the field of epidemiological methods and health statistics since 1987 were analyzed by trend analysis in order to have a better understanding of the development,current situation and history in the field of epidemiological methods and health statistics,and provide reference for the selection of topics,approval of projects and optimization of supporting structure in the field of epidemiological methods and health statistics.
ABSTRACT
Energy conservation has become a problem needing to be immediately solved with the extensive con-struction of hospital information system. As a high computing technology, green computing uses resources economically and effectively and is characterized by energy conservation and environment friendship. Its concept and characteristics, and the status quo of hospital information system construction were described. A green computing framework model was established for hospital information system construction, which plays an active role in implementing the idea of green environment protection, low carbon and energy conservation, and sustainable development, thus laying a foundation for studying the mechanisms underlying energy conservation in hospital information system construction and for assessing and optimizing its strategic system.
ABSTRACT
Drug toxicology,as a discipline which studies drug toxicity mechanisms and evaluates comprehensive drug safety is of crucial importance for guiding sensible clinical drug use,reducing adverse drug reactions and reducing failures of new drug development caused by toxicity. This article summarizes the basic situation of Natural Science Foundation of China(NSFC)funded projects in drug toxicology between 2001 and 2015,involving the amount of approved grants,funding rate,funding category and supported faculty,and the change of NSFC guidelines. Research topics,ideas and contents of NSFC funded projects are generalized and characteristics,problems and future trends are also analyzed to provide reference for research on drug toxicology.
ABSTRACT
Assessment of the value of academic libraries is an effective means to describe the value of academic libraries themselves. The dimension and factors for the assessment of the value of domestic and foreign academic li-braries were analyzed according to the assessment of the value of Shanxi Medical University Library, and the frame-work for the assessment of the value of academic libraries was proposed in terms of the impact of academic libraries on higher education.
ABSTRACT
From the perspective of portable monitoring devices,we use an analog front-end AFE4490 design a module of Non-invasive blood oxygen measurement, used to collect human pulse wave signal and peak (valley) value detection and then use the principles of non-invasive oximetry calculated oxygen saturation (SPO2). This design of noninvasive oximetry module has the characteristics of small size, low power consumption, and the results of test show that the measurement of oxygen saturation are correct.
