Research on Applications of Shenmai Injection on Hypertensive ICH Combined with Cerebrocardiac Syndromes

Objective: This study is to observe the therapeutic effects of Shenmai injection on patients with hypertensive ICH and cerebrocardiac syndromes as well as its effects on prognosis. Methods: A total of 72 patients with severe hypertensive ICH and cerebrocardiac syndromes were selected and divided into the control group and the experimental group (Shenmai injection group) randomly, 36 patients in each group. The control group was treated by conventional therapy, while the experimental group was administrated by intravenous drip of the mixture of 50 ml Shenmai injection and 250 ml 5% glucose injection based on the treatment of the control group, once everyday, 2 weeks continuously. Results: Myocardial enzyme indexes of two groups at 3d, 7d and 14d were observed (Table 1). Myocardial enzyme index of the experimental group was improved quickly and significantly. Myocardial enzyme data of two groups at 3d, 7d and 14d were P < 0.05. According to the electrocardiographic examinations results, ECG anomalies of the experimental group at 7d and 14d were also improved quickly (P < 0.05). There are no evident anomalies in GCS scores of two groups at 7d, but GCS score of the experimental group at 14d of the medication was significantly higher than that of the control group (P < 0.05). Conclusions: Shenmai injection has some therapeutic effects on cerebral injuries and myocardial damages. It can treat brain and heart simultaneously, realize the goal of addressing both symptoms and root causes, and improve prognosis of patients with severe hypertensive ICH.

Impact of Toll-like Receptor 4 Deficiency on Cerebrocardiac Syndrome

In order to investigate the role of Toll-like receptor 4 （TLR4） in cerebrocardiac syndrome （CCS）, the partial cerebral ischemia/reperfusion （I/R） models in mice with different TLR4 genotypes were established in the present study. TLR4 wild-type （C3H/HeN） and mutant （C3H/HeJ） mice of 6-8 weeks of age were divided into 4 groups at random： C3H/HeN sham group （n=10）, C3H/HeJ sham group （n=10）, C3H/HeN model group （n=10） and C3H/HeJ model group （n=10）. Partial cerebral I/R was caused by the middle cerebral artery occlusion （MCAO） to duplicate CCS models in mice. After the operation, the electrocardiogram （ECG）, the level of tumor necrosis factor-alpha （TNF-c0 in myocardial tissue and the cardiac pathological changes were observed in each group. It was shown that the brain infarct volume in C3H/HeN model group was larger than that in C3H/HeJ model group （P〈0.01）. The ST segment change and T wave inversion occurred frequently in model groups. Moreover, the TNF-ct level in C3H/HeN model group was higher than that in C3H/HeJ model group （P〈0.01）. The myocar- dial injury was aggravated in C3H/HeN group as compared with C3H/HeJ group. It was concluded that TLR4 was implicated in the development of CCS.
