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.

Objective To evaluate the value of contrast-enhanced ultrasound (CEUS) in preoperative classification for hilar cholangiocarcinoma. Methods Forty-six patients with 46 hilar cholangiocarcinoma were diagnosed by surgical pathology in Zhongshan Hospital of Fudan University from January 2007 to April 2013. The echogenicity difference on conventinal ultrasound and CEUS were compared with chi-square test. The accuracy of conventinal ultrasound and CEUS for evaluating invaded bile duct, detective rates for portal vein invasion and displaying rate of metastatic hilar lymph nodes were compared with chi-square test or Fisher’s Exact test according to the golden standard of operative exploration. Results On CEUS, 82.6%(38/46) and 91.3%(42/46) hilar cholangiocarcinoma were hypoechoic in portal vein phase and delayed phase respectively, while 63.0%(29/46) hilar cholangiocarcinoma were isoechoic on conventinal ultrasound with vague margin. The clearly displaying rates were 37.0%(17/46), 84.8%(39/46) and 91.3%(42/46) in conventinal ultrasound, portal vein and delayed phase of CEUS and the echogenicity was signiifcantly different. The evaluation accuracy of hilar cholangiocarcinoma invading bile duct was improved from 80.4%(37/46, conventinal ultrasound) to 100%(46/46, CEUS) significantly (χ2=7.882,P=0.005). Portal vein invasion were found in 9 cases during operative exploration and the detective rates on conventinal ultrasound and CEUS were 78%(7/9) and 89%(8/9) without signiifcant difference (P=1.000). Metastatic hilar lymph nodes were found in 8 cases and the displaying rates on conventinal ultrasound and CEUS were the same (75%, 6/8) without signiifcant difference (P=1.000). Conclusions CEUS could signiifcantly improve the clearly displaying rate of hilar cholangiocarcinoma and improve the evaluation accuracy for invaded bile duct comparing with conventinal ultrasound.
