A Comparative Study of Myocardial Damage Caused by Novel Coronavirus Infection and Influenza A Virus Infection in Children during the COVID-19 Epidemic Period

Objective: To explore the comparative study of myocardial damage in children infected with COVID-19 and influenza A virus during the COVID-19 pandemic. Method: Retrospective analysis of myocardial injury caused by COVID-19 infection and influenza A virus infection in children during the COVID-19 from October 2022 to May 2023, including 106 cases of COVID-19 infection, that is, the COVID-19 group;And 164 cases of influenza A virus infection, namely, H1N1 group;Two groups were tested for various indicators of myocardial enzyme spectrum, and the situation of myocardial injury was compared between the two groups. Result: In the enrolled cases, there was no statistically significant difference in the prevalence rate of men and women in the COVID-19 group (P > 0.05);There was no statistically significant difference in the average age between men and women (P > 0.05);The comparison of the incidence rates between males and females in the H1N1 group showed a statistically significant difference (P 0.05);There was no statistically significant difference in the average age between the two groups of girls (P > 0.05). A comparison between two groups of various indicators of myocardial enzyme spectra showed that the results of AST, -HBDH and LDH were statistically significant (P 0.05). Conclusion: Both COVID-19 infection and influenza A virus infection in children have different degrees of myocardial damage, but COVID-19 infection causes more myocardial damage than influenza A virus infection, and influenza A virus is more prone to myocardial infarction, which deserves our attention.

Correlation Study of Color Doppler Examination of Deep Veins of Both Lower Extremities Combined with Fibrinolysis System in Hypertension during Pregnancy

Objective: To investigate the correlation between deep static color Doppler ultrasound of both lower extremities combined with fibrinolytic system detection in pregnancy-induced hypertension. Methods: A total of 70 normal pregnant women, 70 pregnant women with hypertension during pregnancy, and 50 healthy non-pregnant women in the same period were selected as the research objects. The deep veins of both lower limbs were examined by Rili Erlangshen’s color Doppler ultrasound diagnostic instrument (CDU), and the fibrinolysis system was tested by enzyme-linked immunosorbent assay (ELISA) method and automatic hemagglutination analyzer. Results: Compared with the non-pregnant group, the inner diameters of the left/right femoral vein (CFV) and popliteal vein (POV) in the normal pregnancy group and the pregnancy-induced hypertension group were significantly widened, and the peak blood flow spectrum was significantly reduced. The difference was statistically significant (P < 0.01);FIB, PLG, t-PA, PAI, D-Dimer were significantly increased, the difference was statistically significant (P < 0.01);Compared with the normal pregnancy group, the inner diameter of the left/right femoral vein (CFV) in the hypertensive pregnancy group was significantly wider than that in the normal pregnancy group, and the peak value of the left/right POV blood flow spectrum was significantly lower than that in the normal pregnancy group, the difference was statistically significant (P < 0.01), while the left/right popliteal vein (POV) inner diameter, left/right CFV blood flow peak value did not change significantly from the normal pregnancy group, and the difference was not statistically significant (P > 0.05);FIB, PLG, PAI, D-Dimer of the hypertensive disease group during pregnancy significantly increased, the difference was statistically significant (P < 0.01), while t-PA was not statistically significant (P > 0.05). Conclusion: Normal pregnant women have a hypercoagulable state compared with healthy non-pregnant women, and pregnant women with hypertension during pregnancy are more likely to be in a pre-thrombotic state than pregnant women with normal pregnancy. Deep vein CDU examination of both lower extremities combined with blood fibrinolysis monitoring is of great value in the prevention and treatment of hypertension during pregnancy.

Research Progress on Psychosocial Adaptation of Hemodialysis Patients

From the perspective of the biopsychosocial medical model,hemodialysis patients often suffer from psychosocial maladaptation in the face of a series of changes and pressures,which greatly affect their physical and mental health.This paper reviews the concept of psychosocial adaptation of hemodialysis patients,the current research status,influencing factors,measurement tools,and the current status of interventions,aiming to provide a reference for improving the psychosocial adaptation ability of hemodialysis patients.

Analysis of the Current Situation and Influencing Factors of Psychosocial Adaptation of Hemodialysis Patients

Objective:To investigate the current status and influencing factors of psychosocial adaptation of hemodialysis patients,and to provide a reference basis for the development of nursing interventions.Methods:435 hemodialysis patients from the hemodialysis centers of three tertiary A hospitals in Xi’an City were conveniently selected from April to August 2023,and were investigated using the General Information Questionnaire,the Psychosocial Adaptation to Disease Scale,the Fear of Disease Progression Simplification Scale,and the Personal Sense of Control Scale.Results:The psychosocial adaptation score of hemodialysis patients was(56.68±18.32);the results of multiple linear regression analysis showed that marital status,the form of payment for medical expenses,work status,degree of self-care in daily life,number of co-morbid chronic illnesses,fear of disease progression,and sense of personal mastery were the main influencing factors of psychosocial adaptation of hemodialysis patients.Conclusion:The psychosocial adaptation of hemodialysis patients is at the level of severe maladaptation,and healthcare professionals should formulate scientific and reasonable nursing intervention programs according to their influencing factors to enhance their psychosocial adaptation.

覆盖件型面拉延筋参数化设计系统

研发了一套覆盖件型面拉延筋参数化设计系统。设计了拉延筋的参数化模型,提出了拉延筋自动设计方案。系统采用自适应曲线离散方法得到拉延筋截面控制点,基于垂直截平面完成拉延筋截面线的几何参数化设计,利用控制截面线类型的方式完成混合拉延筋的生成和过渡,最后通过曲面扫掠结合端头光顺处理方法完成拉延筋的三维几何实体建模。该方法避免了冲压负角和建模失败,可快速、准确地创建矩形、圆形和混合拉延筋。通过汽车后盖内板拉延型面的拉延筋自动化设计案例,验证了该系统的有效性和实用性。

The Application Research of WBC Morphology Combined with NAP in the HFMD Co-Infection of Children

In this manuscript the authors have studied the application value of White blood cell morphology combined with neutrophils alkaline phosphatase staining integral value in treatment of pediatric HFMD combined with infection. They showed that comparing the NAP positive rate of HFMD co-infection with the NAP positive rate of other three groups respectively—reference group, HFMD group and anti-infection HFMD group—the t value is 25.7964, 28.2326, 28.3696 and the values of P are 0.0000;Comparing the NAP integral value of HFMD co-infection with the NAP integral value of other three groups respectively, which are reference group, HFMD group and anti-infection HFMD, the t value is 35.8687, 36.2664, 36.1374 and the values of P are 0.0000. They concluded that it is useful to apply WBC morphological examination combined with the positive rate and integral value of NAP staining to diagnose and treatment HFMD.
