Objective To investigate the correlation between inflammatory cells, body temperature changes, and TCM syndromes of deep venous thrombosis (DVT) patients in acute and subacute phases. Methods The data of age, gender, body temperature, blood routine, venous ultrasonography, and four diagnostic information of 130 DVT patients in acute and subcute phases were collected and analyzed in a cross-sectional study. The correlation between inflammatory cells and the changes of body temperature and TCM syndromes were analyzed. Results Among 130 DVT patients, 37 patients had damp-heat syndrome, 64 patients had blood stasis and dampness syndrome, and 29 patients had qi stagnation syndrome. Neutrophils increased most obviously in blood stasis and dampness syndrome (P<0.05), which had close correlation with the skin redness (OR=1.287, 95%CI: 9.412-21.247). The mononuclear cells increased most obviously in the damp-heat syndrome, which has close correlation with nouhof (OR=7.364, 95%CI:1.189–45.603), high skin temperature (OR=6.683, 95%CI:1.791–24.938), skin tightness (OR=6.107, 95%CI:1.423–26.203) and weakness (OR=3.302, 95%CI: 1.002–9.169). The temperature rising was the most common in the damp-heat syndrome, and the increase of mononuclear cells was the most common one. Conclusion DVT is often accompanied with elevated levels of inflammatory cells and body temperature. Damp-heat syndrome has close correlation with body temperature and mononuclear cells increasing. Dampness and blood stasis syndrome and neutrophils are closely related.

OBJECTIVETo express the fusion protein of glutathione S-transferase (GST) and human Id-2 in E. coli and prepare the polyclonal antibodies against Id-2.

METHODSThe coding sequence of Id-2 gene was amplified by RT-PCR from the total RNA of breast cancer tissue. The recombinant plasmid was identified by PCR, restriction endonuclease digestion analysis and sequencing. The fusion protein GST-Id-2 expressed in E. coli following IPTG induction was purified by glutathione-agarose affinity chromatography and used to immunize rabbits to prepare the polyclonal antibodies against GST-Id-2.

RESULTSPCR, restriction endonuclease digestion and sequence analyses showed that the Id-2 gene had been correctly inserted into pGEX-6P-1 vector, and the GST-Id-2 fusion protein expressed had a relative molecular mass of approximately 40,000 as shown by SDS-PAGE. The polyclonal antibodies obtained from the rabbit sera were found to specifically react with purified Id-2 by Western blotting, ELISA and agar gel immunodiffusion (AGP).

CONCLUSIONThe prepared polyclonal antibodies against Id-2 allow effective Id-2 detection and facilitate further investigation of the structure and antigen epitope of Id-2.
