ABSTRACT

Prostate cancer with refractory hyponatremia is rare. A patient was admitted with urinary retention, who developed weakness, apathy, and altered mental status during hospitalization, and was diagnosed with severe hyponatremia. After multidisciplinary consultations with departments such as endocrinology and neurology, the patient was diagnosed with syndrome of inappropriate antidiuretic hormone secretion (SIADH). The patient received serum PSA test and prostate MRI examination, and was diagnosed with prostate cancer by prostate biopsy. Laparoscopic radical prostatectomy was successfully performed. Results: The patients took tolvaptan orally before operation to maintain normal serum sodium. One month after radical prostatectomy, the symptoms of fatigue and anorexia disappeared, and serum sodium returned to normal without tolvaptan taking and sodium supplementation. No tumor recurrence or hyponatremia relapse observed during the 6-month follow-up.

ABSTRACT

Objective The aim of this study was to investigate the polymorphism of SLA class II genes in Canadian SPF Yorkshire and Landrace pigs.Methods Blood samples were obtained from 15 SPF Yorkshire and 22 Landrace pigs for isolation of peripheral blood mononuclear cells respectively, and the DQB1, DRB1 and DQA genes were amplified by PCR after reverse transcription.SLA class II genes were obtained by analyzing the direct and cloning result.The polymorphism of alleles was analyzed using the DNAsp 5.0 software.Results A total of 25 alleles were identified at three genes, including eight DQB1, ten DRB1 and seven DQA, and three alleles were submitted the complete sequences for the first time.The official allele names were assigned as SLA-DQB1*0212 (KU754590), SLA-DQB1*0203 (KU754591) and DRB1*06:07(KU754601) by the SLA Nomenclature Committee.Three novel DQA alleles were discovered.Five of the 15 amino acids, one of the 16 amino acids and 11 of the 19 amino acids, which bind processing antigens, showed well conserved among the alleles of DQB1, DRB1 and DQA genes in the SPF Yorkshire and Landrace pigs, respectively.Neighbor-joining tree showed that the three genes were divided into two clusters, respectively.There was a close relationship between SPF Yorkshire and Landrace pigs and foreign Yucatan miniature pigs, and it showed no obvious genetic distance with other pigs.Conclusions A total of 25 SLA class II alleles have been identified successfully in this study, and there are more abundant polymorphism for them.There is a widely distribution for SLA class II alleles identified in this study in other pig breeds.It is critical for the eventual future use of SPF Yorkshire and Landrace pigs as classical laboratory animal models.

ABSTRACT

Objective To determine the reproductive physiology and blood physiological and biochemical characteristics of SPF Yorkshire and Landrace swine.Methods Ten reproductive physiology parameters,19 blood physiological parameters and 18 blood biochemical parameters in SPF Yorkshire and Landrace swine were measured using conventional methods and the differences between population,between age groups and between both sexes were analyzed.Results There were no significant differences(P>0.05) in reproductive physiology parameters and most blood physiological and biochemical parameters of the SPF Yorkshire and Landrace swine.A few of parameters,such as blood physiological indices GRAN,HGB,RDW,PLT,PCT,and blood biochemical indices ALKP,CHOL,TBIL,BUN,showed significant difference(P<0.05) between populations,between age groups and between both sexes,however,the values of difference were rather small,deviated from the normal range.Conclusion The physiological and biochemical characteristics of SPF Yorkshire and Landrace swine are basically stable and there is no significant difference compared with other laboratory miniature pigs.This study will provide valuable basic data for raising velvet yield,establishment of animal models and evaluating the genetic quality of closed colony.
