Effects of gastrodin on the expression of brain aging-related genes in SAM/P-8 mice based on network pharmacology.

Background: Gastrodin can reduce neuronal damage through multiple targets and pathways, and can be useful in preventing and treating degenerative lesions of the central nervous system, but the specific mechanism has not been elucidated.

Methods: The aging-related genes in the hippocampus and the frontal cortex were detected in adult and aged mice treated with gastrodin or not. In addition, we collected the target genes of gastrodin and aging from a network database, and a Venn diagram was created to obtain the intersection target genes of gastrodin and aging.

Development of a model based on the age-adjusted Charlson comorbidity index to predict survival for resected perihilar cholangiocarcinoma.

Background: Perihilar cholangiocarcinoma (pCCA) has a poor prognosis and urgently needs a better predictive method. The predictive value of the age-adjusted Charlson comorbidity index (ACCI) for the long-term prognosis of patients with multiple malignancies was recently reported. However, pCCA is one of the most surgically difficult gastrointestinal tumors with the poorest prognosis, and the value of the ACCI for the prognosis of pCCA patients after curative resection is unclear.

[Progesterone and its receptor in male reproduction].

Progesterone, as a female hormone, plays an important role in the physiological function and pregnancy maintenance in women. Recent studies show that progesterone and its receptor are also involved in male reproduction, and its receptor mRNA exists in male sexual glands. It is believed that progesterone, binding to its receptor, can regulate spermatogenesis and improve the fertilization of sperm, while the sperm from those with oligospermia, asthenozoospermia, teratospermia or unexplained infertility exhibit a low fertility due to the deficient expression of the progesterone receptor and insensitive reaction to progesterone.
