BACKGROUND: Numerous studies have shown that Danshen Root can suppress adhesion and aggregation of neutrophils as well as production of oxygen free radical, can activate blood circulation to dissipate blood stasis. However, there are few studies about precise mechanisms underlying protection of vascular endothelium and anti-thrombosis, especially concerning the mechanism of action following coronary artery stent implantation.OBJECTIVE: To investigate the influence of Danhong injection on vascular endothelial function before and after coronary artery stent implantation in patients with acute coronary syndrome (ACS). METHODS: A total of 60 ACS patients were randomly assigned to two groups. The patients in the conventional treatment group were subjected to conventional drug treatment following coronary artery stent implantation. The patients in the Danhong injection group received conventional drug treatment and Danhong injection (20 mL/d) following coronary artery stent implantation. The treatment course was 10 days. Before and after implantation as well as before and after Danhong injection treatment, endothelium-derived blood flow-mediated vasodilation, plasma endothelin, thromboxane B2, 6-keto-prostaglandin levels were determined, and the vascular endothelial function were evaluated. Simultaneously, short-term prognosis was observed in patients of both groups.RESULTS AND CONCLUSION: Plasma endothelin and thromboxane B2 levels were significantly increased, but 6-keto-prostaglandin levels were significantly decreased following stent implantation in patients of both groups compared with that before implantation (P < 0.05). Plasma endothelin and thromboxane B2 levels were significantly reduced, but endothelium-derived blood flow-mediated vasodilation and 6-keto-prostaglandin levels were significantly increased in both groups following treatment compared with that following implantation (P < 0.05, P < 0.01), especially in the Danhong injection group (P < 0.05). During hospitalization, the incidences of cardiovascular events were diminished in the Danhong injection group compared with conventional drug treatment group (P > 0.05). Results suggested that Danhong injection significantly improves vascular endothelial function, induces vasodilatation, improves blood supply, inhibits platelet aggragation, and shows the tendency of ameliorating short-term prognosis.

DBJECTIVE: To evaluate the efficacy of traditional Chinese medicine in the treatment of complications following cerebrovascular stent placement.METHODS: A computer screen was performed for Science Direct database and Ei database between January 1960 and October2009,using key words of"traditional Chinese medicine,stent placement,complication",and the language was limited to English.At the same time,Chinese Journal Full-text database and Chinese Biomedical Literature database between January 1994 and October 2009 were searched for related articles,using key words of"traditional Chinese medicine,cerebral blood vessels,stent placement,complications",and the language was limited to Chinese.In addition,several monographs were manually consulted.The basic and clinical trials addressing the prevention and treatment of traditional Chinese medicine on the complications following cerebrovascular stenting were included.RESULTS: Subsequent to the cerebrovascular stent placement,the traditional Chinese medicine interventions include benefiting Qi,invigorating blood circulation,and eliminating phlegm,which all serve as the basic approach,in addition these interventions are accompanied by relieving Qi and stagnancy in liver,soothing the nerves and benefiting water,cooling blood and stopping bleeding.The commonly used traditional Chinese medicine compound is consisted of Shengmai San,Buyang Huanwu decoction,Xuefu Zhuyu decoction,sini decoction and resist decoction.Modern pharmacological studies have shown that a large number of traditional Chinese medicine and compound which are always used to benefit Qi,invigorate blood circulation,dissipate blood stasis and eliminate phlegm,can effectively prevent the complications following cerebrovascular stent placement through a multi-component,multi-target,multi-channel integration regulatory role.CONCLUSION: The traditional Chinese medicine interventions during the peri-operative period of cerebral vascular stent placement exhibit a feature of Chinese medicine and play an important role for improving the success rate of surgery,preventing and reducting peri-operative period and long-term complications.

The management of patients with cancer of unknown primary site (CUP) is a notoriously medical problem. The outcome is bad in most patients. The clinical general characteristics, histopathology, im-aging features and endoscopies can provide some useful information, and the primary site can be detected in part of these patients, but most are not. With the application of molecular biology and positron emission tomography-computed tomography(PET-CT) technology, the detection rate of CUP has increased significantly.

In this paper, we describe mismatch, chaos, and disorder behavior during healthcare seeking. Such structural imbalances, scarcity and surplus make healthcare services less efficient. We give reasons for such phenomena in terms of long-term effects of health resource allocation policy-making and implementation, inherent de-fects within healthcare insurance, incomplete market development, and cultural issues. We then propose four policy strategies, including rational price mechanism, strict referral healthcare system, confidence in basic healthcare facili-ties, and proper healthcare cultures. These will restore orderly healthcare behavior and help realize expectations for the current healthcare reform in China.
