Objective To explore the clinical efficacy of continuous intravenous pump of Shengmai injection for treatment of patients with acute coronary syndrome(ACS)combined with cardiogenic shock. Methods In the period from January 2005 to March 2011,33 hospitalized patients with ACS complicated by cardiogenic shock were selected in the treatment group,and in the same period,32 in-patients with ACS were enrolled in the control group, According to traditional Chinese medicine(TCM)syndrome type,the treatment group was subdivided into Yin xutype(Yin deficiency,15 cases),Qi xu type(Qi deficiency,11 cases),Xue yu type(blood stasis,7 cases). Conventional western medicine treatment was given to the two groups,besides,Shengmai injection in 30-60 mL intravenous drip,once a day was applied in the control group,while in the treatment group,Shengmai injection in 10-100 mL/h trace pump continuous intravenous infusion was given,after the blood pressure returned to normal,the infusion was changed to 5 mL/h trace pump continuous intravenous injection for consecutive 5-7 days. After treatment, the changes of clinical efficacy,blood pressure,heart rate ,improvement of clinical symptoms were observed in two groups,and the changes of mean arterial pressure(MAP)in cases with different syndromes in treatment group were also investigated. Results The rates of the significant therapeutic effect and total effect in the treatment group were obviously higher than those in the control group〔significant effect:69.7%(23 cases)vs. 46.9%(15 cases);the total efficacy:90.9%(30 cases)vs. 62.5%(20 cases),both P<0.05〕. The comparisons of blood pressure and heart rate before and after treatment in the two groups were not significant(all P>0.05). After 48 hours of treatment in the two groups,the clinical symptoms were all improved〔chest pain:2 cases(6.1%)vs. 10 cases(31.3%),sweating:3 cases(9.1%)vs. 13 cases(40.6%),shortness of breath:4 cases(12.1%)vs. 12 cases(37.5%),all P<0.05;heart palpitations:5 cases(15.2%)vs. 9 cases(28.1%),nausea:3 cases(9.1%)vs. 4 cases(12.5%),both P>0.05〕. In treatment group,the increase of MAP in patients withYin xutype(mm Hg,1 mm Hg=0.133 kPa)was higher than that in patients with Qi xu type and Xue xu type(105.00±8.53 vs. 91.00±9.53,89.00±3.53,both P<0.05). Conclusion Continuous intravenous injection of Shengmai injection has significant therapeutic effect for treatment of patients with ACS combined with cardiogenic shock.

Objective To explore the effect of Buyang Huanwu decoction(BYHWD)on protein kinase B1 (AKT1)and c-Jun amino terminal kinase 1/2(JNK1/2)in rats after focal cerebral ischemia. Methods According to the random number table method,48 Sprague-Dawley(SD)rats were randomly allocated to four groups:normal control group,sham-operated group,model group,traditional BYHWD group(each n=12). The rat model of right focal cerebral ischemia was established by the method of middle cerebral artery occlusion(MCAO). The rats in BYHWD group were ingested with the decoction of BYHWD 14.2 g/kg after 2 hours of the operation(the main ingredients of BYHWD including astragalus mongholicus 120 g,Chinese angelica 6 g,radix paeoniae rubra 4.5 g, rhizoma ligustici wallichii 3 g,safflower 3 g,peach kernel 3 g,earthworm 3 g),once a day for 7 days. Other groups of animals were given the same amount of normal saline orally. After operation,on the 7th day,the animals were killed,and their brains were taken out. The reverse transcription-polymerase chain reaction(RT-PCR)assay was used to detect AKT1 mRNA expression,and immunohistochemical method was applied to measure JNK1/2 protein expression. Results Compared with normal control and sham-operated groups,the level of AKT1 mRNA expression〔absorbance(A)〕was decreased obviously(0.48±0.08 vs. 0.63±0.11,0.61±0.09,both P<0.05),and the number of JNK1/2 positive cells(cell/mm2)was increased significantly(34.13±4.57 vs. 16.15±1.09,16.23±2.05,both P<0.05)in model group;compared with model group,the AKT1 mRNA expression in brain tissue(0.93±0.11)and the number of JNK1/2 positive cells(45.04±5.68)was increased significantly in BYHWD group,the differences being statistically significant(P<0.05 or P<0.01). Conclusion BYHWD can up-regulate expressions of AKT1 mRNA and JNK1/2 positive cells in ischemic brain tissue that is one of the mechanisms in the protection of brain.

Objective To investigate the effect of Shanzha Xiaozhi capslue on intima-media thickness(IMT) and plaques score of carotid artery in patients with non-acute phase coronary heart disease and traditional Chinese medicine(TCM)syndrome of phlegm and blood stasis. Methods A prospective study was conducted to carry out a research on 102 patients with non-acute phase coronary heart disease and TCM syndrome of phlegm and blood stasis. They were randomly divided into two groups:a control group(50 cases)treated with conventional western medicine alone and a observation group(52 cases)which was treated by both conventional western medicine and Shanzha Xiaozhi capslue(the main TCM ingredients:Shanzha,Dahuang)0.7 g,3 times a day,the therapeutic course being 6 months in both groups. The cardiocerebral vascular incidences of the two groups were observed,in the mean time,the carotid artery IMT and plagues score were registered,the scores of phlegm stagnation syndrome and blood-stasis syndrome were measured,adverse reaction was observed and compared in both groups before and after treatment. Results After treatment,the occurrence of major adverse acute cardiovascular and cerebrovascular events in observation group were reduced significantly compared with those in the control group(5.77%vs. 20.00%,P<0.05). The IMT and plaques score of carotid artery and the scores of phlegm stagnation syndrome and blood-stasis syndrome were all decreased obviously compared to those before treatment,and the effect was more remarkable in the treatment group〔IMT of carotid artery(mm):0.80±0.13 vs. 0.95±0.12,the plaques score:1.35±0.65 vs. 1.75±0.88, phlegm syndrome score:20.98±6.42 vs. 35.55±9.22,blood-stasis syndrome score:23.23±5.12 vs. 28.95±6.38, P<0.05 or P<0.01〕. Abdominal pain appeared in 2 patients of observation group without other adverse reactions. Conclusion Shanzha Xiaozhi capsule can stabilize atherosclerotic plaque and reduce the occurrence of acute adverse cardiocerebral vascular events in patients with non-acute phase coronary heart disease and phlegm and blood stasis syndrome possibly by removing phlegm and blood stasis to decrease the IMT and plaques score of carotid artery.
