To analyze the composition regularity of prescriptions containing Scutellaria baicalensis in Drug Standard of Ministry of Public Health of the Peoples Republic of China--Chinese Patent Medicines and Preparations on the basis of the traditional Chinese medicine inheritance support system (TCMISS), in order to provide reference for new drug R&D. the platform's software V2.0 was applied to establish a database of prescriptions containing S. baicalensis. The software's statistical statement module, association rules and improved mutual information method and other data mining technologies were adopted to analyze commonly used drugs, combination rules and core combination of S. baicalensis prescriptions. Having analyzed 477 prescriptions containing S. baicalensis, the researchers summarized 45 most commonly used drug combinations, whose ingredients mostly had functions of heat-clearing and damp-drying, purging fire for removing toxin and hemostasis. Drugs adopted in core combinations were relatively concentrated and selected according to definite composition methods. There were 23 diseases that S. baicalensis were most frequently applied in the treatment. Having compared three highly frequent diseases--cold, cough and dizziness, the researchers concluded that S. baicalensis could show different therapeutic effects through different combination ratios. Therefore, TCMISS (V2.0) is an important tool in analyzing the composition regularity of traditional Chinese medicines. The longitudinal and parallel comparison method is an effective method for studying the clinical composition regularity of S. baicalensis, while providing reference for new drug R&D.

Background and purpose:In recent years, epigenetics research has become a new direction of cancer research. A large number of results have shown that the abnormal changes of epigenetic modifications have close connection with cancer. Genome-wide epigenetic modifications have become new markers for cancer. This study aimed to investigate the methylation of the promoter ofDBC1 gene in cervical cancer tissues of Uyghur women in Xinjiang, to explore the correlation between the gene methylation and the infection of HPV, and to evaluate whether it can be used as a tool with high sensitivity and specificity for cervical cancer screening.Methods:This study detected the infection of HPV16, 18 in 43 normal cervical tissues, 35 cervical intraepithelial neoplasia tissues and 54 cervical cancer tissues using the polymerase chain reaction (PCR) method. The methylation of the promoter ofDBC1 gene in above-mentioned tissues was detected by the methylation-specific PCR method. The expression ofDBC1 at mRNA level was measured by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) in 10 methylation-negative normal cervical tissues and 10 methylation-positive cervical cancer tissues.Results:In normal cervical tissues, CIN tissues and cervical cancer tissues, the infection ratios of HPV16 were 18.6%, 34.3% and 68.5%, respectively; the infection ratios of HPV18 were 2.3%, 8.6% and 16.7%, respectively; and the methylation ratios ofDBC1 gene were 23.3%, 40.0%, 87.0%, respectively. In 79 high-grade squamous intraepithelial lesions (CINⅡ and Ⅲ) and cervical cancer tissues, 50 of 79 were infected with HPV16/18, while 29 of 79 were negative. The methylation ratio ofDBC1 gene was 88.0% in HPV16/18 infection positive group while the methylation ratio was 55.2% in negative group (P<0.05). The expression ofDBC1 gene at mRNA level in 10 methy- lation-positive cervical cancer tissues was significantly lower than that in the 10 methylation-negative normal cervical tissues (P<0.05).Conclusion:The methylation ofDBC1 gene may become a molecular marker to detect cervical cancer of Uyghur women in Xinjiang.DBC1 gene methylation combined with HPV16/18 infection test can be used to aid diagnosis of cervical cancer.

OBJECTIVETo analyze protein changes in the lung of Wistar rats exposed to gaseous formaldehyde (FA) at 32-37 mg/m3 for 4 h/day for 15 days using proteomics technique.

METHODSLung samples were solubilized and separated by two-dimensional electrophoresis (2-DE), and gel patterns were scanned and analyzed for detection of differently expressed protein spots. These protein spots were identified by MALDI-TOF-MS and NCBInr protein database searching.

RESULTSFour proteins were altered significantly in 32-37 mg/m3 FA group, with 3 proteins up-regulated, 1 protein down-regulated. The 4 proteins were identified as aldose reductase, LIM protein, glyceraldehyde-3-phosphate dehydrogenase, and chloride intracellular channel 3.

CONCLUSIONThe four proteins are related to cell proliferation induced by FA and defense reaction of anti-oxidation. Proteomics is a powerful tool in research of environmental health, and has prospects in search for protein markers for disease diagnosis and monitoring.

OBJECTIVETo study the genotoxicity effect of environmental tobacco side-stream smokes (ETSS) on oxidative DNA damage and its molecular mechanism.

METHODSDNA adduct 8-hydroxydeoxyguanosine (8-OHdG) was used as a biomarker of oxidative DNA damage. The level of 8-OHdG in DNA exposed to ETSS was detected by high performance liquid chromatography with electrochemical detection. Organic and inorganic components in ETSS were analyzed by gas chromatography-mass spectrum and atomic absorption spectrum respectively.

RESULTSParticle matters (PMs) and volatile organic compounds (VOCs) in ETSS could directly induce oxidative DNA damage and formation of 8-OHdG. There were 123 and 84 kinds of organic components in PMs and VOCs respectively, and 7 kinds of inorganic components in ETSS. Some components, especially quinones and polyphenols in ETSS, could produce free radicals in vitro by auto-oxidation without any biological activity systems, and with the catalytic reaction of metals, the DNA adduct 8-OHdG was produced.

CONCLUSIONETSS have biological oxidative effect on DNA in vitro and in vivo, and expressed direct genotoxicity. 8-OHdG is a valuable biomarker of oxidative DNA damage.
