RESUMO
@#Objective To summarize the experience of surgical treatment of transposition of the great arteries with intact ventricular septal (TGA-IVS) after left ventricular regression by comparing the characteristics of rapid and long-term two-stage arterial switch operation (ASO). Methods Forty-one patients who were mainly diagnosed with TGA-IVS from January 2007 to January 2019 and underwent two-stage ASO were included. They were divided into a rapid two-stage ASO group (19 patients) and a long-term two-stage ASO group (22 patients) according to the interval of left ventricular training surgery and ASO. The clinical effectiveness of the two groups was compared. Results There was a statistical difference in age, body weight, blood oxygen saturation before ASO, end diastolic diameter of left ventricle before training, and thickness of posterior left ventricular wall before ASO (P<0.05). Children older than 1 year was an independent risk factor for long-term two-stage ASO. Conclusion Long-term two-stage ASO is suitable for children who are older than 1 year and who have severe left ventricular regression.
RESUMO
The adrenal gland is an important endocrine organ in vertebratesthat produces a wide variety of hormones. The anatomical results showed that the adrenal gland in Bactrian camel had a typical blood supply and innervation. Surprisingly, we found that there was a novel connection mainly consisted of fibrous tissue, blood vessels and nerve bundles between the adrenal gland and the kidney in Bactrian camel, and we named it fibrous tissue-blood vessels-nerve bundles (FBN bundle). To the best of our knowledge, this FBN bundle was the first reported in Bactrian camel, and not yet observed in other animals. While, its functions and mechanisms should be studied further. We speculated that a direct function of this novel path might be to strengthen the communication of the adrenal gland and the kidney. So this communicationpath might have importantadaptive significance for the Bactrian camel living in arid and semi-arid ecological zones.
La glándula suprarrenal es un órgano endocrino importante en los vertebrados, que produce una amplia variedad de hormonas. Los resultados anatómicos mostraron que la glándula suprarrenal en el Camello bactriano tiene un patrón de suministro sanguíneo e inervación típico. Excepcionalmente, se encontró una conexión infrecuente que consistió principalmente en tejido fibroso, vasos sanguíneos y haces nerviosos entre la glándula suprarrenal y el riñón del Camello bactriano, denominándose haz de tejido fibroso-vasos sanguíneos-nervio (Haz FSN). Este paquete de haces de nervios es el primero reportado en el Camello bactriano, y aún no se observa en otros animales, en consecuencia sus funciones y mecanismos deben ser estudiados. Creemos que podría existir una función directa de esta nueva vía para mejorar la comunicación de la glándula suprarrenal y el riñón. Así, esta vía de comunicación podría tener un importante significado adaptativo para el Camello bactriano, quien vive en zonas ecológicas áridas y semiáridas.
