[Laparoscopic orchiopexy for inguinal palpable cryptorchidism].

Objective: To investigate the feasibility and advantages of laparoscopic orchiopexy in the treatment of inguinal palpable cryptorchidism.

Methods: This study included 773 cases of inguinal palpable cryptorchidism with 869 undescended testes, 218 on the left, 459 on the right and 96 bilaterally. The patients were aged 6 months to 8 years, averaging 20 months.

[Preparation of hispidulin chitosan microsphere and its antiproliferation effect ].

Hispidulin(HPDL) chitosan microspheres were prepared in this study to deliver HPDL to the lesion sitevia intravenous injection, and further evaluate their anticancer effects in vitro and the growth inhibition effect on A549 cells spheroids. HPDL chitosan microspheres were prepared by emulsion crosslinking method with chitosan as a drug carrier and the amount of HPDL was determined by high performance liquid chromatography (HPLC). The morphology of microspheres was observed under laser scanning confocal microscope.
