Objective:To approach the status quo and characteristics of traditional Chinese medicine(TCM) in intefering the related cardiovascular risk factors in obese type 2 diabetes mellitus(T2DM).Methods:The recent 10 years documents about nitric oxide(NO),endothelin(ET),C reactive protein(CRP),and etc.,eight cytokines which are involved in T2DM and its cardiovascular complications were retrieved and statistically analyzed and all related TCM were pykno-analyzed.Results:① CRP was the focal point at home and abroad,adiponectin(APN) was the hot spot in recent years.② The documents of ET at home was greatly more than that abroad,it may hint some diversity between different races.③ The related TCM were mainly characterized by cleaning heat,enriching yin and qi,activating blood circulation and removing stasis.④ ET and NO were the hot spots in the TCM fi eld.Conclusion:TCM had certain effect on the cardiovascular risk factors above in obese T2DM.

An analytical method was developed for the simultaneous extraction and determination of three quaternary ammonium compouds ( QACs) in soil samples using ultrasonic extraction and gas chromatography-mass spectrometry( GC-MS) . The qualitative and quantitative analysis of the three analytes dodecyltrimethyl ammonium chloride ( DTAC) , cetyltrimethyl ammonium bromide ( CTAB) and didodecyldimethyl ammonium chloride ( DDAC) were conducted by application of EI mass spectra and selected ion monioring ( SIM ) . Characteristic ions of the QACs were m/z 58 ( DTAC and CTAB) and m/z 212 ( DDAC) . To achieve optimum extraction efficiency, several impact factors including types of extractants, pH of extraction, concentration of linear alkylbenzene sulfonates ( LAS) , extraction times and content of purification column were investigated. Methanol with pH 3. 5 and 40 μg/L LAS solution were selected as extractant. Soil sample was extracted by treated methanol each 10 mL for 20 min every time. Extract of the soil sample was purified by neutral alumina column with 4 cm in length and 1cm in diameter, and then was determineted by GC-MS. Good linear relationships of all the three QACs were obtained in the range of 0. 02-2. 0 mg/L. The limits of determination (LOD, S/N=3) was 1. 2-4. 5 μg/kg. The method was used to analyse real soil samples ( paddy soil, lateritic red soil, and ore tailings) collected from a mining district in south China. Results of determination exhibited the concerntrations of the three analytes in real soil samples ranged from 0 . 24 mg/kg to 0. 41 mg/kg, and their recoveries ranged from 76% to 113% with relative standard deviations ( RSD) of 1. 1%-12. 9% in three different spiked concentrations of 0. 2, 0. 5 and 1. 0 mg/kg.
