China Pharmacy 2016;27(19):2654-2656
OBJECTIVE:To study the preventive effects of arhinhor-11 on acute alcoholism in mice. METHODS:48 mice were randomly divided into model group (sodium carboxymethyl cellulose),arhinhor-11 low-dose,medium-dose and high-dose groups [1.23,2.46,4.92 g(crude drug)/kg],with 12 mice in each group. Each group was given relevant medicine intragastrically, and 30 min later given 56% liquor intragastrically to induce acute alcoholism model. The disappearance time and recovery time of righting reflex were determined. 160 mice were grouped,given medicine and modeled with the same method,with 40 mice in each group. The alcohol concentration and alcohol dehydrogenase(ADH)activity in liver of 10 mice were determined 0.5,1,2,3 h af-ter giving alcohol. Other 10 mice were included in normal control (ig administration of sodium carboxymethyl cellulose). RE-SULTS:Compared with model group,the disappearance time of righting reflex were prolonged while recovery time shortened in arhinhor-11 groups,and alcohol concentration and ADH activity increased 0.5,1,2,3 h after giving alcohol (P<0.05 or P<0.01),especially 1 h after giving alcohol. 3 h after giving alcohol,alcohol concentration in blood of arhinhor-11 high-dose group decreased while ADH activity increased (P<0.05);there was no statistical significance among other arhinhor-11 groups (P>0.05). CONCLUSIONS:Arhinhor-11 has preventive effect on acute alcoholism in mice. It has a positive control effects on the alco-hol concentration in blood and ADH activity in liver.

Objective: To observe the clinical efficacy of long-snake moxibustion plus Western medicine for chronic heart failure due to heart-kidney yang deficiency.Methods: A total of 80 patients were randomized into a control group and an observation group, with 40 cases in each group. The control group was treated with routine Western medicine, and the observation group was treated with long-snake moxibustion therapy on the basis of routine Western medicine. Left ventricular ejection fraction (LVEF), stroke volume (SV) and left ventricular end-diastolic diameter (LVEDd) were measured before and after treatment, and the heart function was assessed. The serum brain natriuretic peptide (BNP) level was measured, the 6 min walking distance was recorded, and the Minnesota living with heart failure questionnaire (MLHFQ) was assessed and scored. The serum galectin-3 (Gal-3) and soluble growth stimulation expressed gene 2 (sST2) protein levels were measured. Clinical efficacy was evaluated after treatment. Results: The total effective rate of the observation group was higher than that of the control group, and the difference between the two groups was statistically significant (P<0.05). After treatment, LVEF and LVEDd in both groups were significantly improved (all P<0.05), and LVEF, SV and LVEDd in the observation group were superior to those in the control group (all P<0.05). The heart function classification in both groups were improved after treatment (both P<0.05), and the heart function classification in the observation group was superior to that in the control group (P<0.05). The serum BNP level in both groups decreased (both P<0.05), and the serum BNP level in the observation group was lower than that in the control group (P<0.05). The 6 min walking distance and MLHFQ scores in both groups were improved (all P<0.05), and the 6 min walking distance and MLHFQ score in the observation group were superior to those in the control group (both P<0.05). The serum Gal-3 and sST2 levels in the observation group decreased significantly (both P<0.05), and all lower than those in the control group (both P<0.05). Conclusion: Long-snake moxibustion plus Western medicine has significant efficacy in treating chronic heart failure due to heart-kidney yang deficiency; it can improve heart function, reduce the serum BNP level, and improve the exercise endurance and quality of life in the patients. This may be related to the down-regulation of serum Gal-3 and sST2 levels.
