Objective:To investigate the contributing factors to elevated blood pressure in borderline cases during medical selection for recruitment of Air Force flying cadets in order to enhance the accuracy of selection.Methods:Blood pressure was measured among 2 350 male high school graduates in the 2022 re-selection phase of medical selection of Air Force flying cadets. None of the participants had a family history of hypertension according to previous health checkups. Identified through blood pressure measurement, subjects with borderline hypertension were assigned to an intervention group (self-intervention with personalized correction plans) and a control group (self-intervention alone) using a random number table. Standardized blood pressure measurements and comprehensive medical history reviews were performed to compare pre- and post-intervention outcomes across the 2 groups, followed by an investigation into the causative mechanisms of elevated blood pressure.Results:Among the 102 cases of borderline hypertension (51 per group) identified, primary contributing factors included the white-coat phenomenon (41.2%), pre-examination physical activity (17.6%), pre-examination medications (3.9%) and poor sleep quality (35.3%). No significant differences in systolic blood pressure (SBP) or diastolic blood pressure (DBP) were observed between the 2 groups at baseline (both P>0.05). After interventions, the intervention group showed significantly lower SBP ( t=3.13, P=0.002) and DBP ( t=7.68, P<0.001) than the control group. Both groups exhibited reductions in SBP and DBP from baseline ( t=6.63, 8.97, 4.13, 2.03, P<0.001, <0.001, <0.001, =0.043). The percentage of students with normal blood pressure was 96.1% (49/51) in the intervention group and 78.4% (40/51) in the control group. Conclusions:Transient blood pressure elevation in selection settings primarily stems from the white-coat phenomenon, physical exertion, medications and sleep disturbances. Standardizing blood pressure measurement protocols and addressing transient factors can help avoid unwarranted disqualifications and ensure the accuracy of selection.

Objective:To explore the relationship among internet / reality alienation, irrational beliefs and depression in medical college students.Methods:In October 2021, a total of 501 students from five medical colleges in Shandong were selected by the convenient sampling method.All the participants were assessed by the internet alienation scale, general alienation scale, irrational beliefs scale and self rating depression scale.SPSS 24.0 software was used for descriptive analysis, correlation analysis, and AMOS 21.0 software was used to conduct structural equation modeling and Bootstrap mediated effect test.Results:The scores of internet/reality alienation, irrational beliefs and depression were 3.12±1.35, 2.04±0.57, 2.72±0.72, 2.07±0.42, respectively.There was a statistically significant positive correlation among internet/reality alienation, irrational beliefs and depression( r=0.56-0.64, P<0.01). Structural equation modeling showed that the mediating effect of irrational beliefs between internet alienation and depression was 0.05(95% CI=0.01-0.11). The mediating effect of irrational beliefs between reality alienation and depression was 0.16(95% CI=0.06-0.30). Conclusion:Internet/ reality alienation can indirectly effect depression of medical college students through the mediation of irrational beliefs.
