OBJECTIVETo observe the effect of Shen warming Pi strengthening method on expressions of serum T cell subsets (C045+%, C03+%, and C04 +/COB+) in diarrhea-predominant irritable bowel syndrome (IBS-0) rats. Methods An IBS-0 rat model was established referring to AL-Chaer's modeling method combined with tail clamp and intragastric administration of sanna leaf. After modeling 30 SO rats were randomly divided into 6 groups according to random digit table, i.e., the model group, the high, middle, low dose Wenshen Jianpi Recipe (WJR) groups, and the Sishen Pill control group, 6 in each group. A normal control group consisting of 6 SO rats were also set up. Rats in high, middle, low dose WJ R groups were administered by gastrogavage with boil-free WJ R at the daily dose of 3. 100, 1. 550, 0. 775 g/kg, respectively. Rats in the Sis hen Pill control group were administered by gastrogavage with boil-free Sis hen Pill at the daily dose of 0. 736 g/kg. Equal volume of normal saline was given by gastrogavage to rats in the model group and the normal control group. All medication lasted for 2 successive weeks. Rats' general state, expressions of T cell subsets (CD45+%, CD3+%, and CD4+ /CDB+) changes were observed.

RESULTSCompared with the normal control group, expressions of CD45+% and CD3+% increased, but CD4+ /CDB+ decreased with statistical difference (P < 0. 05). Compared with the model group, expressions of CD45+% and CD3+% decreased, but CD4+ ICDB+ increased with statistical difference in high, middle, low dose WJR groups, and the Sis hen Pill control group (P <0. 05). Compared with the Sis hen Pill control group, there was statistical difference in all indices except CD45+ value in the low dose SWPSM group (P <0. 05). Compared with the low dose WJ R group, the expression of CD3+% decreased in high and middle dose WJR groups, and the Sis hen Pill control group; CD4+ /CD8+ increased in the Sishen Pill control group and the high dose SWPSM group (all P < 0. 05).

CONCLUSIONSWJR showed better treatment effect. The mechanism of Shen warming Pi strengthening method might be achieved by regulating expressions of CD45+% and CD3+%, and CD4+ /CD8+ ratios.

The complete genomes of more cyanobacterial strains have been completed for sequence, and genetic engineering of cyanobacteria has evolved in the post-genome era. Since Kaneko and colleagues had completed the sequence for the complete genome of Anabaena sp. PCC 7120 in 2001, functions of some genes in this genome, including fructose-1,6-bisphosphate aldolase (FBA) gene, have been predicated using the method of bioinformatics. However, little information is available regarding whether this gene can encode FBA and its product characteristics of related enzyme. Here, to explore this information, the predicted II-FBA gene-encoding region in Cyanobase database was cloned by PCR method and then ligated into pET-32a to generate the expression vector, pET-FBA-II. The results of SDS-PAGE indicated that the expression level of the expected target polypeptide was approximate 23.4 percent as compared to total protein and the molecular weight is about 40 kDa as compared to the protein molecular marker. The results of enzyme activity analysis showed that the activity of II-FBA was ~11.8 U per mg protein and owned a standard activity of II-FBA. To sum up, the results not only prove the functional prediction of this II-FBA gene from the Cyanobase database, but also provide the important conditions for further studying its physiological and biochemical characteristics and functions of the gene expression product.
