1.The number of origin,points of entrance,and relationship with other structures of the renal arteries were studied in 111 adult male and 9 female cadavers. It was found that 84.2?2.35% belonged to 1 branch-type,of which 73.4?4.03% occurred bilaterally;the two-branch type consisted only 15.4?2.33%;the three branch type being only 0.4?0.41%. 2.The average height of origin of the renal arteries from the aorta was at the level of intervertebral disc between the 1st and 2nd lumbar vertebrae,of which 50.0?5.23% were equal in height on both sides;in 34.1?5.05% the right side was higher than the left and in 15.9?3.90% was the reverse. 3.When two renal arteries were present,the accessory one arose at a lower level than the main artery,ranging from the level of lower border of the 1st lumbar vertebra to that of the upper border of the 5th lumbar vertebra. 4.In 78.2?2.90% of the cases,the renal arteries entered the kidney through the hilum,the rest of them entered dinectly into the kidney substance,most of which through the upper extremity of the kidney. 5.When two renal arteries were present,both entered the hilum in 75.0?7.21% of the cases. 6.In most of the cases (83.7?2.60%),the renal artery divided outside of the hilum.Its primary branches could be divided into 5 types,most of which were of the anterior-posterior or superior-inferior types.They were 59.1?3.88 and 34.3?3.65% respectively. 7.The relationship of the accessory renal artery with the ureter and the inferior venal cava was discussed.

Objective:To explore the status and influencing factors of self-care ability in patients with primary bile reflux gastritis (PBRG) , so as to provide a reference for formulating targeted nursing strategies.Methods:From January 2020 to June 2021, 150 PBRG patients in the First Affiliated Hospital of Zhengzhou University were selected by convenience sampling as the research objects. The General Information Questionnaire, Exercise of Self-Care Agency (ESCA) , Chinese short version of Depression Anxiety and Stress Scale (DASS-C21) , and General Self-Efficacy Scale (GSES) were used for the investigation. Multiple linear regression analysis was used to explore the influencing factors of self-care ability in PBRG patients. A total of 150 questionnaires were distributed and 145 valid questionnaires were recovered, with a valid recovery rate of 96.67%.Results:Among 145 PBRG patients, the total scores of the ESCA, DASS-C21 and GSES were (110.43±19.75) , (22.60±4.13) and (25.59±5.21) respectively. Multiple linear regression analysis showed that educational level, poor psychological state, self-efficacy, family monthly income per capita and payment method were the influencing factors of self-care ability of PBRG patients ( P<0.05) . Conclusions:The self-care ability of PBRG patients needs to be further improved. Clinical medical and nursing staff should formulate targeted interventions according to their influencing factors to improve the self-care ability of PBRG patients.
