Thrombotic diseases in different forms become a great threat to human health. Such anti-platelet aggregation drugs as aspirin and clopidogrel are common drugs in clinic. However, along with the appearance of resistance and side effects of western anti-platelet aggregation drugs, anti-platelet aggregation traditional Chinese medicines promoting blood circulation to remove blood stasis have gradually become an important study orientation. Platelet is one of major participant in thrombosis, and plays an important role as a bioactive material in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, mainly involving two aspects--the evaluation for the anti-platelet aggregation activity of traditional Chinese medicines and the screening of their active components. This paper summarized the applications of platelets in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, so as to provide basis for further studies.

OBJECTIVETo evaluate the efficacy and safety of the combination therapy of Xipayimaizipizi Capsules and Tamsulo- sin in the treatment of benign prostatic hyperplasia (BPH).
METHODSWe randomly assigned 60 BPH patients to a control and a combination group of equal number, the former aged 62.03 ± 10.19 years with a disease course of 3.24 ± 2.18 years and the latter aged 64.77 ± 10.33 years with a disease course of 4.09 ± 2.63 years. We treated the patients in the control group with Tamsulosin at 0.2 mg qd and those in the combination group with Tamsulosin at 0.2 mg qd plus Xipayimaizipizi at 0.5 g tid, respectively, both for 4 weeks. Then, we obtained the mean frequency of nocturnal urination, maximal urinary flow rate (Qmax), residual urine volume, International Prostate Symptom Score (IPSS) , and quality of life scores (QOL) of the patients, and recorded their adverse reactions.
RESULTSBefore treatment, the nocturnal urination frequency, Qmax, IPSS, and QOL were 3.60 ± 1.81, (10.40 ± 3.53) ml/min, 22.47 ± 8.58, and 4.43 ± 1.50 in the control group, as compared with 3.43 ± 1.61, (10.14 ± 3.43) ml/min, 21.93 ± 8.79, and 4.73 ± 1.31 in the combination group. After 4 weeks of medication, the combination group showed more significant improvement than the control in the nocturnal urination frequency (1.30 ± 1.18 vs 2.27 ± 1.60), Qmax ([13.85 ± 3.15] vs [14.36 ± 3.03] ml/min), IPSS (13.00 ± 1.53 vs 17.20 ± 8.43), and QOL (2.57 ± 1.61 vs 2.93 ± 1.68), all significantly better than the baseline (P < 0.05). The combination therapy achieved remarkable improvement as compared with the control in the nocturnal urination frequency (- [2.13 ± 1.11] vs -[1.73 ± 1.07]), IPSS (- [8.93 ?6.01] vs -[4.80 ± 3.87]), and QOL (- [2.17 ± 1.12] vs -[1.50 ± 1.01]) (P < 0.05), but exhibited no significant differences from the latter in Qmax ([3.72 ± 2.281 vs [3.95 ± 2.53] ml/min) and residual urine volume (- [34.30 ± 37.43] vs - [26.43 ± 30.49] ml) (P > 0.05). Adverse reactions were found in 5 cases in the combination group (16.67%) and 3 cases in the control (10%) , with no remarkable differences between the two groups (P > 0.05).
CONCLUSIONThe combination therapy of Xipayimaizipizi Capsules and Tamsulosin can improve the symptoms of BPH and the patients quality of life of.
