Quantitative nuclear magnetic resonance (qNMR) technology has significant advantages in quantification due to its simple sample processing and high reproducibility. Two-dimensional qNMR analysis, which can solve the quantification problem of different components in complex systems, has gradually been applied in medicine, food, metabonomics, chemical engineering, and other fields. This paper reviews the analysis methods, influencing factors, experimental optimization, application fields, and other aspects of qNMR to promote its wide and effective application.

Objective To ascertain serum inflammatory markers could be modified following treatment of periodontal disease in elderly patients. Methods The probing depth (PD), clinical attachment level (AL), C-reactive protein (CRP), interleukin-6 (IL-6) were determined. And then fifty-two elderly periodontitis patients underwent a standard phase of non-surgical periodontitis treatment (consisting of oral hygiene instructions and subgingival scaling and root planning). After three and six months, PD, AL, CRP and IL-6 were determined again and compared to the baseline. Results Six months after treatment, significant reductions in PD [(5.9±1.1) mm vs. (6.8±1.0) mm, P<0.05], AL [(1.3±0.9) mm vs.(8.4±1.1) mm, P<0.05], CRP [(1.5±0.2) mg/L vs. (2.0±0.3) mg/L, P<0.01] and IL-6 [(1.6±0.5) ng/L vs. (1.9±0.4) ng/L, P<0.05] were observed. Conclusions Treatment of chronic periodontitis can decrease the levels of serum inflammatory markers in elderly patients.

Objective To study the methods of preparing samples, analyse free radical in smoke of cigarette and the relationship between free radical and the other harmful components in the cigarette smoke. Methods The contents of two types of free radical in smoke of 13 kinds of cigarettes were determined with electron spim resonance(ESR) and the self-made equipment. Results The analytic results showed that the main component was the free radical in gas state in all cigarette samples and it was about 10-30 times higher than the content of free radical in solid state. The content of free radical in gas state of cigarette made in China was lower than that made in foreign country. Conclusion The analysis method using ESR and the self-made equipment will be easily used in the related experiment; The level of free radical in gas and solid state is positively related to the level of tar and nicotine in the cigarette sample of same trademark but it is not the same in the samples of different trademark. Therefore, we can not to infer the content of free radial in cigarette smoke by the content of tar and nicotine in it,especially for the content of free radial in gas state. Using charcoal filter is benefit to reduce the level of free radical in cigarette smoke.

The content of benzyl isothiocyanate (BITC) which as the enzymatic hydrolysis product of benzyl glucosinolate through thioglucosidase was determined by HPLC. The chromatography condition was as follows: Kaseisorb LC ODS 2000 (4.6 mm x 150 mm, 5 min) column with the mobile phase of acetonitrile(A)-water( B) under gradient elution (0-5 min, 3%-8% A; 5-9 min, 8%-48% A; 9-23 min, 48%-62% A; 23-28 min, 62%-99% A); the flow rate was 1.0 mL x min(-1) with 10 microL injection volume; detection wavelength was 246 nm and temperature of column was 40 degrees C. The content of benzyl glucosinolate was in the range of 10.76-17.91 g x L(-1). The method is simple, accurate and good reproducibility which can be used for the determination of benzyl glucosinolate in Lepidium meyenii, effectively.

OBJECTIVETo investigate the intervention effect and mechanism of compound Ginkgo biloba (CGB) preparations on nonalcoholic fatty liver disease (NAFLD).
METHODThe C57BL/6 mouse NAFLD model was induced with high fat diets. Since the 2nd week after modeling, the mice were orally administered with 600 and 200 mg x kg(-1) x d(-1) CGB for eight weeks. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), cholesterol (CHOL) and LPS in serum, as well as pathological changes and expression of tumor necrosis factor-alpha (TNF-alpha) in hepatic tissues were observed. Changes in intestinal tight junction proteins ZO-1, Occludin, Claudin-1 in intestinal tissues were determined under microscopy.
RESULTCompared with the normal group, the model group showed obvious fatty degeneration in rat livers, with notable increase in TNF-alpha expression (P < 0.01), significant increases in ALT, AST, TG, CHOL and LPS in serum (P < 0.01, P < 0.05), injury in intestinal tight junction proteins, and remarkable declines in ZO-1, Occludin and Claudin-1 (P < 0.01). Compared with the model group, CGB high and low dose groups showed obvious relieves in fatty degeneration in rat livers and injury in intestinal tight junction proteins, significant reductions in TNF-alpha expression (P < 0.01, P < 0.05) and AST, TG, CHOL and LPS in serum (P < 0.01, P < 0.05) and remarkable increases in ZO-1 and Occludin expressions (P < 0.05).
CONCLUSIONCGB can protect intestinal tight junction proteins, reduce intestinal leakage, relieve fatty degeneration and inflammations in livers and prevent NAFLD occurrence and development.

"Omics" and bioinformatics have brought new ideas to the study of traditional Chinese medicine. This study used metabonomics and network pharmacology to investigate the pharmacodynamic basis and regulation of Qishen Yiqi dropping pill (QDP) improving cardiac energy metabolism in rats with heart failure (HF). 1H NMR metabonomics analysis showed that eight metabolites, including carnitine, glutamine, creatine, proline, homocitrulline, lactic acid, taurine and alanine appeared significant callback after QDP treatment for HF. The results indicate that QDP regulates the metabolism of carbohydrate, lipid, ATP and protein. The animal experiment was conducted in accordance with the regulations of the Ethics Committee for Experimental Animal Management and Animal Welfare of Institute of Materia Medica, Chinese Academy of Medical Sciences. A "drug-component-target-disease" network was established using network pharmacology, and the "component-target" sub-network related to the above energy metabolism processes was extracted by combining metabonomics results. Results revealed 79 chemical compounds and 47 potential targets of QDP involved in the regulation of energy metabolism, and identified key chemical components including ursolic acid, notoginsenoside G, ginsenoside-Rh1, and core targets such as INS, PPARG, and AKT1. The results also demonstrated the complex multi-target and multi-component relationship between QDP and HF from the perspective of energy metabolism. The molecular docking technique verified a strong interaction between some targets and chemical compounds, with affinities less than -5 kcal·mol-1. The results of this study provide useful information for the clinical application, development, and utilization of QDP.
