Deep-seated brain tumors can be difficult to differentiate. Three tumor types (primary central nervous system lymphoma [PCNSL], high-grade glioma, and metastatic brain tumors), identified by susceptibility-weighted imaging, have different relationships with small medullary veins, and these relationships can be used to enhance diagnostic accuracy. ⋯ An MVB is an accurate sign for differentiating metastatic brain tumors from two other common malignancies and thus provides a useful tool for preoperative planning.

Observational Study
Inhibitory concentration of propofol in combination with dexmedetomidine during microelectrode recording for deep brain stimulator insertion surgeries under general anesthesia.
Microelectrode recording (MER) for target refinement is widely used in deep brain stimulator insertion for Parkinson disease. Signals may be influenced by anesthetics when patients receive general anesthesia (GA). This study determined the inhibitory concentration (IC) of propofol on MER signals when it was coadministered with dexmedetomidine. ⋯ Our data provided reference values of propofol for dosage adjustment to avoid interference on MER under GA when anesthetics have to be continuously infused during recording.

Chronic pain is a common postoperative complication in patients undergoing major surgery and may significantly affect their quality of life (QOL). Whether patient-controlled analgesia (PCA) can reduce the risk of chronic postsurgical pain and promote long-term QOL is still unclear. ⋯ Patients using intravenous PCA had a better QOL in physical health over time after major surgery, which may have been due to factors other than pain-relieving effects.

Mucinous gastric carcinoma (MGC) is rare and often associated with an advanced stage. The clinicopathological features and prognosis of MGC and non-MGC (NMGC) are controversial. ⋯ MGC itself was not an independent prognostic factor of worse survival. MGC was correlated with higher PD-L1 expression than NMGC, which may have a clinical impact on the treatment of MGC in the future.

Meta Analysis
Less invasive surfactant administration in preterm infants with respiratory distress syndrome-an updated meta-analysis.
Less invasive surfactant administration (LISA) seems to have a good application prospect both in experimental models and patients with respiratory distress syndrome (RDS). Data regarding the effect of LISA procedure on RDS are conflicting. ⋯ Based on the above evidences, LISA is an effective and safe treatment for preterm infants with RDS.
