Clinical evaluation of modified ALPPS procedures based on risk-reduced strategy for staged hepatectomy.

Introduction And Objectives: Radical resection remains the only curative treatment for liver tumors. Although associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) can increase the resection rate, huge controversy exists for high reported mortality and morbidity. This study was to evaluate the efficacy and safety of modified ALPPS procedure.

[Expression of estrogen receptor alpha in the testis of infertile men with spermatogenic arrest].

Objective: To explore the association of spermatogenic arrest with the expression of estrogen receptor alpha (ERalpha) in human testes.

Methods: We examined the testicular biopsy specimens of 120 infertile men by HE staining, detected the expression of ERalpha in the specimens of those with spermatogenic arrest by the two-step immunohistochemical method, and compared the results with those of 10 healthy men.

Results: Of the 120 specimens from the infertile men, 31 (25.
