[Chaotic dynamic process of multiple organs dysfunction syndrome and the regulatory function of shenqin liquid on it].

Abstract

OBJECTIVE:

To explore the chaotic dynamic process of multiple organs dysfunction syndrome (MODS) and the regulatory effect of Shenqin Liquid (SQL), a Chinese herbal liquid preparation with the action of purging and qi-tonifying.

METHODS:

Eighty SD rats were divided into 4 groups, and were given suspension of zymosan A and paraffine (1 mL/kg) by peritoneal injection except for those in the blank control group to set up the multiple organs dysfunction syndrome (MODS) model. Low and high doses SQL were administered twice at the doses of 30 and 60 g/kg of SQL respectively at an interval of 8 h per day before modeling. Serum concentration of tumor necrosis factor alpha (TNF-alpha) and nitric oxide (NO) in MODS model animals were tested diachronically, eg. 12, 6 h before modeling, during modeling, 6 and 12 h after modeling, and then the mathematic models were built up with compartment analysis. Lyapunov exponents (LE) of the mathematic models were calculated to evaluate their chaotic characteristics of movement and the degree of chaos was ascertained with the correlation dimension (CD).

RESULTS:

The serum levels of TNF-alpha and NO were significantly higher than those in the bland control group at modeling, 6, and 12 h after modeling (P <0.01), while those in the low and high doses of SQL were significantly lower than the model group (P <0.01). Moreover, the level of NO in the high dose of SQL was significantly lower than that in the low dose group (P <0. 01). CD of TNF-alpha movement in the blank control group was 0.803 with the LE less than zero; those in the model group was 1. 966 and > 0 respectively; in the low dose and high dose SQL treated groups, CD was 0.517 and 0.653 respectively and LE >0. CD of NO movement in the blank control group was 0.670 and with LE < 0; in the model group, 1.242 with LE > 0; in the low dose SQL group, 0.574 and in the high dose SQL group 0.850, and LE <0 in the two groups.

CONCLUSION:

Under the normal physiologic condition, TNF-alpha and NO moved steadily without chaotic properties; while under the pathologic condition of MODS, they manifest relatively complicated chaotic properties. SQL can intervene the movement of TNF-alpha and NO, decrease the complexity of their chaotic movement, and make them return back to a stable state.
