ABSTRACT
Objective:To discuss the treatment strategies and experiences of total anomalous pulmonary venous connection (TAPVC) and study the risk factors for postoperative pulmonary venous obstruction (PVO).Methods:Clinical data of 125 children with TAPVC in the Children Heart Center of Fuwai Central China Cardiovascular Hospital from January 2018 to December 2020 were included in this study and analyzed retrospectively.Of the 125 cases, 116 were treated surgically.They were divided into 2 groups according to whether PVO appeared after repair of TAPVC.The t-test or chi- square test was used to compare the clinical data of the 2 groups, and Logistic regression analysis was adopted to analyze the risk factors for postoperative PVO. Results:Among the 116 patients undergoing surgery, including 73 males (62.9%) and 43 females (37.1%), and according to Darling′s classification, there were 58 cases (50.0%) of supracardiac, 35 cases(30.2%)of intracardiac, 15 cases(12.9%) of infracardiac and 8 cases (6.9%) of mixed.The median age and body weight during surgery were 3.0 (1.2, 7.0) months and 5.0 (4.0, 6.8) kg.There were 13 deaths (11.2%), and recurrent PVO was observed in 18 patients (15.9%). Statistically significant diffe-rences were observed in terms of Darling′s classification (supracardiac 27.8% vs.56.6%, intracardiac 27.8% vs.31.6%, infracardiac 27.8% vs.10.5%, mixed 16.6% vs.5.3%, χ2=8.571, P=0.036) of PVO group and non-PVO group after operation preoperative PVO (83.3% vs.21.1%, χ2=25.293, P<0.01), with confluence (55.6% vs.81.1%, χ2=6.049, P=0.014), preoperative critical state (83.3% vs.31.6%, χ2=12.938, P<0.01), cardiopulmonary bypass time[ (128.800±47.254) min vs.(106.700±37.288) min, t=-2.094, P=0.039 ], delayed thoracic closure(27.8% vs.5.3%, χ2=6.227, P=0.013), and anastomotic velocity at 1 day after operation[1.0(0.9, 1.4) m/s vs.0.9(0.8, 1.1) m/s, Z=-2.004, P=0.045], anastomotic velocity at 1 week after operation[1.4 (1.3, 1.8) m/s vs.0.9 (0.7, 1.1) m/s, Z=-4.446, P<0.001], and mechanical ventilation time[121.0 (76.8, 246.9) h vs.91.5 (60.4, 135.9) h, Z=-1.989, P=0.047]. All of these data were included in the Logistic regression analysis.The results showed that preoperative PVO ( OR=797.179, 95% CI: 8.074-78 712.270, P=0.004) and increased anastomotic flow velocity at 1 week after operation ( OR=11 848.376, 95% CI: 23.746-5 912 017.803, P=0.003) were associated with postoperative PVO. Conclusions:Surgical correction in patients with TAPVC with a biventricular anatomy in this center is satisfactory.Preoperative PVO and early anastomotic flow velocity increase after operation are the high risk factors for postoperative PVO.
ABSTRACT
This study comprehensively analyzes the course of Military Medical Psychology from 7 aspects including the nature and status, teaching objectives, teaching principles, teaching concepts, classroom teaching, practical teaching and lecturing principles, and finally summarizes the characteristics of the course and points out its shortcomings and prospects. The study found that the Military Medical Psychology is an important interdisciplinary course between medical psychology and military science; the teaching objectives include two categories, the overall goals and classified ones; the teaching principle emphasizes the forces of developing practice ability of service orientation; the teaching concept includes combining the theory with practice, focusing on the students, informatization and lectures; the mode of classroom teaching should be cases-introduction, theory-interpretation and case-analysis; the practical teaching should strengthen teaching skills, emphasize connection, stimulate interest and improve the health; lecturing principles emphasize the focus of content. This study has preliminarily completed the teaching design of the course of Military Medical Psychology, which is conducive to the smooth implementation of this course and the cultivation of professional talents of military medical universities.
ABSTRACT
Objective:To analyze the clinical features of 63 azoospermic patients with microdeletion of azoospermia factor C region(AZFc) and their relationship with sex hormones.Methods:The clinical data of 63 azoospermic patients with AZFc microdeletion were retrospectively analyzed, including age, height, body weight, body mass index(BMI), testicular volume, and sex hormones.Results:Compared with normozoospermic men, height, body weight, and testicular volume revealed statistical differences in azoospermic patients with AZFc microdeletion( P<0.05). There were significant differences in FSH, LH, testosterone(T), and prolactin levels between two groups( P<0.05). BMI was negatively associated with FSH level( r=-0.251, P=0.04)and positively associated with estradiol(E 2)level( r=0.327, P=0.009). Age had a negative association with T level( r=-0.256, P=0.04). Testicular volume revealed a negative association with FSH level( r=-0.289, P=0.02). There were no association of height with T, E 2, FSH, and LH levels( P>0.05). Conclusion:It is more likely that azoospermic patients with AZFc microdeletion present overweight and earlier decreased androgen level. The adjustment of lifestyle and testosterone supplementation might be beneficial to the long-term quality of life in these patients.
ABSTRACT
Objective:To systematically evaluate the real experience of caregivers in patients with hematopoietic stem cell transplantation.Methods:The Cochrane Library, PubMed, Scopus, Web of Science, PsycINFO, CBM, CNKI, VIP, and Wan Fang Data were searched for qualitative studies on caregivers' experience of hematopoietic stem cell transplant patients. The time limit for the search was from inception to June 2019. The results were assessed using a pooled integration approach using the Australian JBI Evidence-Based Health Care Center (2016) Quality Evaluation Standards Evaluation.Results:A total of 6 studies were included to refine 27 complete and definitive findings, and similar results were grouped into 8 new categories and integrated into 5 integrated results: the physical and mental experience of the caregiver, dilemmas and needs, caregivers′ coping style, social support in the care process, caregiver adaptation and growth.Conclusion:Medical staff should pay attention to the psychological state and potential needs of this group. In the process of transplantation, the caregiver should be self-regulated and better qualified as a caregiver.
