Dear Editor, We would like to present a rare case ofpolyorchidism. Polyorchidism is an unusual abnormality of the genital tract and until date, there are approximately 178 case reports of polyorchidism in the literature？ However, the most of patients are asymptomatic and usually diagnosed incidentally. Some may present as inguinal hernia （30%）, maldescended testis （15% to 30%）, testicular torsion （13%） and hydrocele （9%）, varicocele （1%）, hypospadias （〈1%）, anomalous urogenital union （〈1%）, and malignancy （〈1%）.2 management of polyorchidism is still controversial. Important factors of polyorchidism management are testis location, size and anatomical organization of the testicular drainage system and the age of the patient.

Adaptability theory is an important tool to analyze the degree, mechanism and process of interaction between human and environment, which provides a new perspective for the research of sustainability assessment. Based on the entropy weight-TOPSIS method and the panel Tobit model from the perspective of adaptability, spatio-temporal difference and influencing factors of environmental adaptability assessment of human-sea economic system in Liaoning coastal area was measured by using the city panel data from 2000 to 2014. The results indicate that: 1) The environmental adaptability of human-sea economic system in Liaoning coastal area rose slowly from 2000 to 2014, the developing trend of each city was linearly related, and Dalian was in a leading position. 2) The different adaptability elements and adaptability subsystem show polarization phenomenon and completely different regional evolution characteristics. The adaptability of human-sea environment system and human-sea economic system rose slowly and had the characteristics of linear relationship, and the adaptability of human-sea environment system is the main reason for the difference of environmental adaptability of human-sea economic system. 3) Science and technology, environmental management, marine economic development level, port construction are the driving factors of the healthy development of environmental adaptability of urban human-sea economic system.
