Nuclear magnetic resonance (NMR) spectroscopy can be used to both identify and quantify chemicals from complex mixtures. Over the last several decades, significant technical and experimental advances have made quantitative nuclear magnetic resonance (qNMR) a valuable analytical tool for quantitative measurements of a wide variety of samples. This particular approach is now being exploited to characterize the metabolomes of many different biological samples and is called quantitative metabolomics or targeted metabolic profiling. In this review, some of the strengths, limitations of NMR-based quantitative metabolomics will be discussed as well as the practical considerations necessary for acquisition with an emphasis on their use for bioanalysis. Recent examples of the application of this particular approach to metabolomics studies will be also presented.

The application of HPLC-NMR-MS hyphenated technique in the structural identification of trace substances from complex mixtures and the identification of endogenous and exogenous substances in the establishment process of metabolic profiling have become effective analytical tools in pharmaceutical chemistry, pharmacological and pharmacokinetic studies of active substances from natural products. Metabolomics method based on NMR technology can accurately portray metabolic phenotypes with the characteristics of diseases and a variety of disease-related pathways, and it can greatly enrich and supplement the traditional disease evaluation methods. So it can be used for pharmacological studies of active substances from natural products, such as toxicological studies, the dose optimization, active substances screening and pharmacodynamic evaluation. Hyphenated technique associated with metabolomics method based on NMR technology will accelerate the speed of the discovery of active substances from natural products, and improve the efficiency of their pharmacological evaluation.

Objective To explore the effect of repetitive transcranial magnetic stimulation (rTMS) on intelligence development in children with cerebral palsy with epilepsy. Methods 156 children with cerebral palsy with epilepsy were randomly divided into control group (n=70) and treatment group (n=86). The control group received comprehensive rehabilitation combined with traditional Chinese and western medicine. The treatment group received rTMS in addition. Both groups were evaluated with the development quotient (DQ) of Gesell Development Schedules and Mental Developmental Index (MDI) of Children's Development Center of China (CDCC) intelligence test before, and 2 and 4 months after treatment. Results The DQ and MDI improved more in the treatment group than in the control group (P<0.001). Conclusion rTMS can improve the intelligent development in children with cerebral palsy with epilepsy.
