Objectives: To examine the associations of specific types of physical exercises, dietary preferences, and obesity patterns with incident hypertension.Methods: In this cohort study, obesity patterns were defined using general and abdominal obesity as G-/A-, G+/A- or G-/A+, and G+/A+. The type of physical exercises and dietary preferences were collected using a validated questionnaire. Participants with systemic blood pressure/diastolic blood pressure ≥140 mmHg/90 mmHg, use of antihypertensive medications, or a self-reported diagnosis were identified as hypertension.Results: There were 10,713 participants in this study. Martial arts, gymnastics, and ping pong could decrease the risk of hypertension (HR: 0.792, 0.884, and 0.855; and 95% CI: 0.743–0.845, 0.825–0.948, and 0.767–0.953, respectively). However, TV or computer usage, and consumption of fast food, soft/sugared drinks, and salty snack food could increase incident hypertension (HR: 1.418, 1.381, 1.233, and 1.225; and 95% CI: 1.315–1.529, 1.269–1.504, 1.157–1.314, and 1.139–1.316, respectively). Obese subjects had an increased risk of hypertension.Conclusion: The type of physical exercises, dietary preferences, and obesity patterns were associated with incident hypertension. More attention should be paid to these lifestyles to benefit health outcomes.

In China, the 10kV distribution network operates with neutral ungrounded. Due to the influence of high transition impedance and branches, the problem of fault location has not been effectively solved. The characteristics of C-type travelling wave method at neutral ungrounded system are analyzed in this paper. Multi-point fault location method based on C-type travelling wave method is proposed. By actively injecting high-voltage pulses into the circuit and using multiple measuring devices to detect the reflected wave of the fault point, the effect of high-impedance- grounded and branch points on the reflected wave of the fault point is effectively reduced, and the success rates of reflected wave detection of the fault point are improved. The validity of the method is verified by simulation.

Penetrating atherosclerotic ulcer (PAU), an uncommon etiology of acute aortic syndrome (AAS), is a potential cause of chest pain seen in emergency departments. As PAU may lead to electrocardiogram (ECG) changes or rarely, elevated troponin levels, it is most likely misdiagnosed as acute coronary syndrome (ACS). Hence, individuals with PAU may be offered potentially life-threatening treatment. This paper reports a case of a 81-year-old male who presented with intermittent chest pain with a history of old inferior myocardial infarction and stent placement in the left circumflex coronary artery (LCX) three years ago. Initially, he was diagnosed with non-ST-elevation myocardial infarction (NSTEMI) based on abnormal ECG changes and raised troponin I. However, emergency coronary angiography (CAG) showed no restenosis in the left circumflex coronary artery (LCX) but with mild stenosis in the left anterior descending artery (LAD) and right coronary artery (RCA). Computed tomographic angiography (CTA) of the whole aorta showed multiple atherosclerotic plaques with penetrating atherosclerotic ulcer in the aortic arch and descending aorta. Endovascular aortic repair with Ankura II covered stent was performed. This case study reminds us that it is clinically difficult to distinguish PAU from ACS. Upon excluding ACS from the diagnosis, we should take into consideration of PAU, especially in elderly patients with positive cTnI.
