ABSTRACT
Objective:To explore the correlation analysis between psychological status and blood pressure of residents in medium-risk areas during the coronavirus disease 2019 (COVID-19) epidemic, and provide references for early psychological intervention and hypertension management during the COVID-19 epidemic.Methods:From January 4 to 8, 2021, the convenience sampling method was used to conduct psychological questionnaire surveys on residents and employees of enterprises in the medium-risk area and surrounding areas of Jiuxianqiao, Chaoyang District, Beijing. General data (gender, age, height, weight, history of smoking and drinking, previous medical history), and home blood pressure monitoring were collected. Pearson′s χ 2 test was used to compare different factors (anxiety, depression, age, gender, body mass index, smoking, drinking, and history of chronic diseases) in normal blood pressure or not. A multivariate logistic regression analysis model was established to explore independent risk factors of abnormal blood pressure. Results:No anxiety accounted for 75% (684/912), and anxiety accounted for 25% (228/912). No depression accounted for 67% (611/912), depression accounted for 33% (301/912). Both anxiety and depression accounted for 23% (210/912). The substandard blood pressure accounted for 10.3% (94/912). The incidence of poor blood pressure control in participants with anxiety was 30.7% (70/228), which was significantly higher than that of participants without anxiety 3.5% (24/684) (χ 2=136.779, P<0.001). The incidence of poor blood pressure control in participants with depression 27.2% (82/301) was significantly higher than that of participants without depression 2.0% (12/611) (χ 2=139.388, P<0.001). Multivariate logistic regression analysis showed anxiety ( OR=3.261, P<0.001), depression ( OR=7.928, P<0.001), and complications of chronic diseases ( OR=3.207, P<0.001) were closely related to whether blood pressure was under control. Conclusions:During the COVID-19 epidemic, the psychological status of residents and employees in medium-risk areas should be screened and interventions implemented accordingly to prevent unstable blood pressure caused by anxiety or depression.
ABSTRACT
Medical intervention is to make use of puncture and catheterization technique for the diagnosis and treatment, relying on the guidance of medical imaging equipment. It is also a new medical branch which is independent of internal medicine and surgery. It is officially named the third largest medical technology. Interventional therapy contains blood vessel intervention and non-vessel intervention. The operation of the catheter and thread in the vessel is the key part of vessel intervention. By comparison it is found that the operation of catheter and thread in the blood vessel is similar to that of the string in the wellbore. Tubular mechanics in oil-gas wells is a mature theoretical mechanics system in the field of Petroleum Engineering. In this paper, the tension-torque model of the tubular mechanics in oil-gas wells is introduced, and the operation of catheter in a simulative vessel is mechanically analyzed with the software of mechanical analysis of drill string in directional wells.

Guided by the principle of multimedia instruction, the author puts forward a new teaching mode, in which theoretical teaching and experimental teaching can be processed synchronously based on campus network, interactive teaching is dominative, students are the principal part, and integral optimization of theoretical teaching and experimental teaching can be realized.
