Traditional Chinese medicine is a treasure of Chinese culture, absorbing the wisdom of the Chinese people. Continuous application of new technologies makes traditional Chinese medicine research advance with the times. After several years of development, high-throughput transcriptome study has become a mature research tool in biology. This paper reviewed the advances in medicine transcriptome study, and compared two sequencing platforms, Roche's GS FLX platform and Illumina's HiSeq 2000 platform. Moreover, this paper introduced medicine transcriptome analysis process, with Panax quinquefolius and Lonicera japonica for examples, showing the characteristics of traditional Chinese medicine transcriptome studies. High-throughput transcriptome studies facilitate traditional Chinese medicine research with overall understand of functional genes, give clear elucidation of metabolic pathways, lay molecular foundation for the traditional Chinese medicine research and offer modern interpretation for traditional Chinese medicine theory. However, the current study faces several difficulties, including weak molecular basis, high sequencing cost and staff shortages in data anaysis. In the future, with the development in sequencing technology, the combination of transcriptome and other genomics, such as proteome and metabolome, will lay a solid foundation for the new high-throughput screening and developing model for the traditional Chinese medicine industry.

OBJECTIVETo evaluate the method for collecting NO2 in workplace air using a solid adsorbent and determining the concentration of NO2 by ion-exchange chromatography.

METHODSNO2 in workplace air was collected using sampling tubes filled with 13X molecular sieve soaked with triethanolamine, and the samples were desorbed with a certain concentration of triethanolamine solution to obtain NO2(-). NO2(-) was separated with an anion exchange chromatography column and quantified by a conductivity detector. The concentration of NO2 was determined based on the conversion coefficient of NO2 and NO2(-).

RESULTSDifferent concentrations of NO2 (standard gas) was collected using the sampling tubes at different time points, and the sampling efficiency and desorption efficiency could reach more than 90%. The penetrating capacity of sampling tubes was more than 1.1 mg. The comparative test shows that there was no significant difference between the new method and national standard method (solution absorption) (P > 0.05). The samples could be stored at room temperature for more than 16 days. The calibration curve plotted in the new method was linear in the range of 0.1∼20.0 µg/ml, with a correlation coefficient of 0.9998; the detection limit was 0.01 µg/ml; the minimum detectable concentration was 0.05 mg/m(3) (V0 = 3.0 L).

CONCLUSIONThis determination method meets the requirements of Guide for establishing occupational heath standards-Part 4 Determination methods of air chemicals in workplace (GBZ/T 210.4-2008) and shows obvious advantages for determination of NO2 in workplace air.

OBJECTIVE: To work out a qualitative diagnostic criterion for basic syndromes of traditional Chinese medicine in patients with primary liver cancer. METHODS: Based on the collection and analysis of related medical literature, clinical investigation, and experts' discussion, a preliminary qualitative diagnostic criterion for basic syndromes of traditional Chinese medicine in patients with primary liver cancer was formulated. Then it was used in clinic to be verified and revised repeatedly till it was improved to be a satisfied formal criterion. RESULTS: The basic syndromes listed in the qualitative diagnostic criterion for basic syndromes in patients with primary liver cancer consisted of two parts: excessive syndromes, including the syndromes of stagnation of qi, blood stasis, excess-heat and dampness, and deficient syndromes, including the syndromes of deficiency of qi, deficiency of blood, deficiency of yin and deficiency of yang. Each of the above syndromes could be diagnosed according to specific combination of its corresponding symptoms or signs. The clinical verification results showed that the total matching ratio was 73.92% between the diagnoses made according to the criterion and the diagnoses acquired from the experts' experience. CONCLUSIONS: The qualitative diagnostic criterion for basic syndromes of traditional Chinese medicine in patients with primary liver cancer is coincident with the experts' clinical practice. However, it needs to be further studied.
