RESUMO
BACKGROUND: Glucose imbalance is common in total parenteral nutrition (TPN). Hypoglycemia seems to be less frequent than hyperglycemia, but it influences the clinical outcome to a greater extent. Therefore, it should be effectively prevented and treated. However, there is no relevant report on how to treat hypoglycemia caused by TPN in patients with liver cell injury. CASE SUMMARY: We present three patients with liver cell injury who developed severe hypoglycemia during or after TPN infusion. The causes of severe hypoglycemia and glucose-raising strategies were discussed. According to the physiological characteristics of the hepatocellular injury, the ratio of nutrition components prescribed in TPN was appropriately adjusted for the three cases. We simultaneously reduced the dose of insulin and fat emulsion, and increased the dose of glucose in TPN. The blood glucose level was restored to normal range and clinical symptoms were eliminated. CONCLUSION: When hypoglycemia occurs during or after TPN in patients with hepatocellular injury, physicians need to simultaneously reduce insulin and fat emulsion, and increase glucose, and correct severe hypoglycemia in time to reduce its adverse consequences.
RESUMO
Two new iridoids, jatamanvaltrates N (1) and O (2), together with four known compounds (3-6), were isolated from the roots of Valeriana jatamansi. Their structures and relative configurations were elucidated by spectroscopic methods (IR, ESI-MS, HR-ESI-MS, 1D, and 2D NMR) and by comparison of their NMR spectral data with those of related compounds. All the isolated compounds were evaluated for their neuroprotective effects, and only compound 1 showed weak neuroprotective activities.
