Intrathecal drug-infusion system for treating pain in advanced cancer: New research in patient management.

Currently, the treatment of cancer pain in China mainly follows the three-step pain relief principles formulated by the World Health Organization. As research on subarachnoid drug diffusion has intensified, intrathecal drug delivery has been gradually applied in the treatment of diseases, and improved analgesia can be achieved via the continuous infusion of small doses of morphine-derived drugs. This method can not only effectively relieve pain and enhance quality of life but also significantly reduce the incidence of nausea, vomiting, constipation, and other adverse reactions caused by the long-term intensive use of drugs in patients with cancer pain.

KS-CMI: A circRNA-miRNA interaction prediction method based on the signed graph neural network and denoising autoencoder.

Methods: Real-time polymerase chain reaction and Western blot methods were performed to examine the expression of APJ and its endogenous ligand apelin in spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats after chronic atRA treatment.

Marine organic pollution history in the Changjiang Estuary and Zhejiang coastal area--HCHs and DDTs stratigraphical records.

The variations of concentrations of hexachloro-cyclohexane (HCHs), dichloro diphenyl trichloroethane (DDTs) in surface sediments from the Changjiang Estuary and Zhejiang coastal area suggests that although there is a substantial decrease of these persistent trace compounds since the last two decades, they still presented in recent surface sediments. Their concentration levels in suspended matter are still quite high. In dated sedimentary cores, the DDTs and HCHs concentration peaks appeared in 1960s to 1980s, which approximately corresponded to their production and usage history.
