The most common site of bone metastasis in advanced bladder cancer is spine，and jaw metastasis is rare. This article reports a 77-year-old male patient who had a solitary metastatic lesion in the left jaw 1 year after radical cystectomy for bladder cancer. The pathological features of the metastasis were consistent with bladder urothelial carcinoma metastasis. The patient received a GC regimen combined with toripalimab immunotherapy for 4 cycles，followed by maintenance of immunotherapy and anti-bone metastasis protection therapy. No new metastasis was found during the 6-month follow-up.

Aim To explore the effect of prenatal expo-sure to lipopolysaccharide ( LPS ) on lipid metabolism in mice offspring from the starting point of FAT/CD36 expression.Methods 8-week old C57 mice mated 2∶1, then they were caged separately , marked as preg-nancy 0 d.The pregnant mice were given single intrap-eritoneal injection of 75 μg? kg -1 LPS, and the con-trol received injections of 0.2 mL saline .The perirenal adipose of female mice and epididymis adipose of male mice were collected in 4 w,8 w,12 w,respectively. The weight of visceral adipose tissue and the free fatty acid( FFA) and triglyceride ( TG) of adipose tissue and FAT/CD36 of offspring mice were quantitated .Results The body weight of offspring of LPS group was also significantly higher than that of NS group , and LPS group offspring displayed increased adipose tissue wet weights , the expression of TG and FFA was increased in LPS group compared with NS .Especially , prenatal exposure to inflammatory stimulation resulted in marked increase of FAT/CD36 and abnormal adipocyte development .Conclusions Inflammation induced by prenatal exposure to LPS results in increased body weight , adipose coefficient and FAT/CD36 that might develop into obesity in adult mice .These results are relevant in that anomalous local adipose tissue and FAT/CD36 regulation may be an important mechanism underlying obesity .

This paper explores the existing gene doping problems of athletes in bioethical aspect,describes the development of gene doping,and points out that strengthening the anti-doping education,further improving legal system and strengthening an effective supervision and anti-doping research are main focus of anti-doping work currently.
