Objective To explore the causes of acute renal failure resulted from tacrolimus in the treatment of nephrotic syndrome. Method The clinical data of acute renal failure caused by tacrolimus in treatment of nephrotic syndrome in 3 children during January 2012 and December 2015 were retrospectively analyzed. Results There were 2 male and 1 female aged 3, 11,and 13 years respectively. Clinical manifestations were consistent with simple type of primary nephrotic syndrome. One child was frequently recurrent and another two were secondary steroid resistant. The renal pathology showed minimal changes. Acute renal failure occurred within 4 weeks after treatment with tacrolimus on the basis of hormone therapy in all patients who had infection within one week. Renal function recovered to normal within 2 weeks after discontinuation or reduction of tacrolimus combined with anti-infection and diuresis treatment. Two children continued with tacrolimus, but the other one was replaced with cyclosporin A. The renal function of all patients remained normal during the follow-up for 10-42 months. Conclusion In the first 4 weeks of tacrolimus therapy in children with nephrotic syndrome, infection may lead to reversible acute renal failure.

Depression is a common emotional disorder that seriously affects people's life and health all over the world. The pathogenesis of depression is complex, and traditional Chinese medicine (TCM) for antidepressants has a good therapeutic effect because of its multi-component, multi-pathway, and multi-target action mode. At present, the anti-depressive mechanism of TCM has not been fully clarified, but it is clear that depression is closely related to metabolic health. Therefore, in order to further explore the anti-depressive mechanism of TCM, this paper proposes research strategies on the anti-depressive mechanism of TCM based on functional metabolomics from the perspective of metabolism, the potential biomarkers of depression are analyzed with the help of multi-omics combined analysis technology, and the functional molecules of TCM for antidepressant are studied. Molecular biology techniques are used to accurately capture the molecular interactions between biomarkers of depression and functional compounds, which identify effective drug targets and further elucidate the biochemical functions and related mechanisms involved in depression metabolic disorders. This paper systematically reviews the research strategies and applications of functional metabolomics in the anti-depressive mechanisms of TCM, expounds on the core value of functional metabolomics, and summarizes the current research status and hot issues of TCM for antidepressants in recent years, providing new methods and new ideas for the study of mechanisms of TCM with the help of functional metabolomics.

Glioma is the most common form of brain cancer. Despite recent advances in the treatment of solid tumors, there are few effective treatments for malignant gliomas due to its infiltrative nature. It has important significance to improve the treatment of glioma through in-depth understanding the intracerebral metabolic characteristics and pharmacokinetics of chemotherapeutics. Brain microdialysis (B-MD), an effective method to monitor central nervous system anticancer drug disposition, conditions of drugs through the blood-brain barrier, basic pathophysiologic metabolism, bioactive compounds and the changes of neurotransmitter in brain, provides the unique opportunity to allow the simultaneous determination of unbound concentrations of drugs in several tissues, and directly measure gliomas biochemistry continuously. B-MD has been able to monitor the change of brain drugs, metabolites and neurotransmitters, dynamic analysis of the drug concentration and pharmacological effect after administration, pharmacodynamic interaction between drugs, receptor mechanism of drug transport, as well as feedback information of internal environment. B-MD is expected to provide reference for clinical individual chemotherapy of glioma, but also provide powerful tools for the evaluation of new anticancer drugs in vivo. In this review, a comprehensive overview of B-MD for studies on glioma is elucidated with special emphasis on its application to neurochemistry and pharmacokinetic studies.
