RESUMEN

Objective@#To research the prevalence and influencing factors of asymptomatic arrhythmia among college students, and provide scientific basis for heart rate control and health management of asymptomatic arrhythmia among college students.@*Methods@#Using cluster sampling method, 3 012 college students who studied in the First Clinical Medical College of Henan University of Traditional Chinese Medicine and the Second Clinical Medical College of Henan University of Traditional Chinese Medicine were selected as the research objects from September to November 2022. After entering school in autumn (September in 2022), all college students were investigated by questionnaire, and the general data and living habits of asymptomatic arrhythmia college students and normal college students were compared. Logistic regression was used to analyze the influencing factors of asymptomatic arrhythmia among college students.@*Results@#A total of 62 patients with asymptomatic arrhythmia were found. The detection rates of the patients with body mass index(BMI)≥24.0 kg/m 2 , systolic blood pressure(SBP)≥120 mmHg, diastolic blood pressure(DBP)≥80 mmHg, family history of cardiovascular disease, smoking, drinking, exercising less than three times a week, heavy study pressure, irregular work and rest, depression tendency and anxiety tendency were 5.58%, 4.49%, 5.63%, 6.18%, 4.26%, 4.50%, 3.72%, 4.29%, 4.28%, 9.15%,9.03%, which were significantly higher than those of patients with BMI<24.0 kg/m 2, SBP＜120 mmHg, DBP<80 mmHg, no family history of cardiovascular disease, no smoking, no drinking, exercise more than three times a week, little study pressure, regular work and rest, no depression tendency and no anxiety tendency (1.20%, 1.37%, 1.35%, 1.53%, 1.55 %, 1.59%, 1.27%, 1.52%, 1.38%, 1.71%,1.71%), and the differences were statistically significant ( χ 2=45.33, 25.20, 37.74, 32.24, 16.69, 17.25, 19.57, 17.83, 22.36, 37.23,39.42, P <0.01). Logistic regression analysis showed that the higher of BMI,SBP and DBP, family history of cardiovascular disease, smoking, drinking, times of exercise, heavy study pressure, irregular work and rest, depression tendency and anxiety tendency were positively correlated with asymptomatic arrhythmia of college students ( P <0.05).@*Conclusions@#The higher of BMI and blood pressure, family history of cardiovascular diseases, bad living habits and psychological status are related to asymptomatic arrhythmia in college students. It is of great significance to control weight and blood pressure reasonably and maintain good living habits and mental state for preventing and improving asymptomatic arrhythmia.

RESUMEN

In order to solve the poor performance of real-time semantic segmentation of night road conditions in video images due to insufficient light and motion blur, this study proposes a scheme: a fuzzy information complementation strategy based on generative models and a network that fuses different intermediate layer outputs to complement spatial semantics which also embeds irregular convolutional attention modules for fine extraction of motion target boundaries. First, DeblurGan is used to generate information to fix the lost semantics in the original image; then, the outputs of different intermediate layers are taken out, assigned different weight scaling factors, and fused; finally, the irregular convolutional attention with the best effect is selected. The scheme achieves Global Accuracy of 89.1% Mean and IOU 94.2% on the night driving dataset of this experiment, which exceeds the best performance of DeepLabv3 by 1.3 and 7.2%, and achieves an Accuracy of 83.0% on the small volume label (Moveable). The experimental results demonstrate that the solution can effectively cope with various problems faced by night driving and enhance the model's perception. It also provides a technical reference for the semantic segmentation problem of vehicles driving in the nighttime environment.

RESUMEN

Taken Huantiao (GB 30) as breakthrough point, acupuncture manipulations of generating various needling sensations by different physicians are sorted. Types of acupoint needling sensations and conducting directions after acupuncture and all kinds of factors that affect needling sensations are analyzed from new perspectives. It is considered that attention should be paid to acupoint location, postures of patients, manipulation methods, types of needling sensations, transmission lines and duration time of needling sensations, etc.

RESUMEN

【Objective】 To investigate the incidence of β-th alassemia (β-thal) heterozygote carrying α-thalassemia (α-thal ) 1 gene in Guangdong area. 【Methods】 β-thal genes were screened by reve rse dot blotting (RDB). In β-thal DNA samples α-thal 1 genes were am plified using gap-PCR method. 【Results】43 α-thal-1 cases were identifi ed among the 500 β-thal traits. The rate is 8.6%. 【Conclusion】 In Guangd ong area the incidence of β-thal heterozygote carrying α-thal-1 gen e is 8.6%, which should be paid much attention in the genetic counselling and pr enatal diagnosis.
