ABSTRACT
Objective To approach the therapeutic effect of modified Linggui Zhugan decoction for treatment of patients with type Ⅱ cardiorenal syndrome (CRS).Methods Thirty patients with CRS admitted to Affiliated Hospital of Tianjin Institute of Chinese Medicine were selected. By a random number table and double-blind method, they were divided into two groups: treatment and control groups, 15 cases in each group. The patients in both groups were treated with conventional western medicine, and those in the treatment group were additionally given traditional Chinese medicine (TCM) modified Linggui Zhugan decoction (including the following ingredients: Poria 30 g, Cinnamomi Cortex 10 g, Atractylodis Macrocephalae Rhizoma 15 g, Glycyrrhizae Radix et Rhizoma Preparata cum Melle 10 g, Morindae Officinalis Radix 15 g, Arecae Pericarpium 30 g, Astragali Radix 30 g, Zingiberis Rhizoma 10 g, Descurainiae Semen 15 g), one dose daily for consecutive 30 days. Before and after treatment the changes in levels of B-type natriuretic peptide (BNP), serum creatinine (SCr), blood urea nitrogen (BUN), amount of urine, clinical efficacy and TCM syndrome score efficacy were observed in two groups.Results After treatment, the levels of BNP, SCr, and BUN were significantly decreased, while urine volume was obviously increased compared with those before treatment in the two groups, and the degrees of changes in the treatment group were superior to those in control group [BNP (ng/L): 297.3±75.1 vs. 344.2±56.3, SCr (μmol/L): 139.7±62.1 vs. 154.4±39.7, BUN (mmol/L): 10.1±6.4 vs. 13.2±8.7, urine volume (mL/d): 847.2±32.7 vs. 786.4±13.6, allP < 0.05]. The total effective rates of patients and TCM syndrome scores in treatment group were significantly higher than those in control group [both 86.7% (13/15) vs. 66.7% (10/15), bothP < 0.05]. Conclusions Modified Linggui Zhugan decoction can alleviate the symptoms of yang deficiency of heart and kidney and heart failure due to the attack of heart by retained fluid, and can also ameliorate the complicated renal function impairment; the therapeutic effect of integrative traditional Chinese and western medicine for treatment of patients with type Ⅱ CRS is superior to that of conventional western medicine treatment.
