Research on post-marketing Chinese medicine should be the systematic study from application to mechanism. Clinical evaluation is the basis of mechanism study, we can find the clue from clinical evaluation, then make a mechanism study to find the reason, then apply the results to clinic. So it is a virtuous circle. In order to achieve it, we cannot be limited to traditional Chinese medicine, we should form multi-disciplinary team under the direction of grand science thinking, try hard to put industry-university-research institute collaboration association to use, and if necessary, explore the new model of the whole nation system. An appropriate operation mechanism is very important.

Objective To investigate the role of intercellular adhesion molecule-1 (ICAM-1) in the up-regulation of peripheral blood somatic stem cells after acute myocardial infarction in rats. Methods The models of acute myocardial infarction were established in 16 rata by ligation of left anterior descending branch of left coronary artery through chest incision, and the animal were divided into control group(n=8) and experiment group (n=8). The hearts of another 2 rats were obtained for normal myocardial tissue sections as controls. Monoclonal antibody of ICAM-1 was infused from the caudal vein in experimental group, and no invervention was conducted for control group. Blood samples were obtained from caudal vein on the first, third, seventh and fourteenth day after operation in these two groups. Serum concentration of ICAM-1 was measured by ELISA, positive rate of CD34 cells in peripheral blood was detected by flow cytometry, and the parameters of concentration of ICAM-1 and positive rate of CD34 cells at each time point were compared between groups. Results The concentration of ICAM-1 in peripheral blood of experiment group reached the lowest of (59.01±2.22) pg/mL on the seventh day. The concentrations of ICAM-1 in peripheral blood of experiment group were lower than those in control group, and there were significant differences between these two groups on the seventh and fourteenth day(P < 0.01). The positive rate of CD34 cells in peripheral blood of experiment group reached the highest of (12±2.11)% on the seventh day. The positive rates of CD34 cells in peripheral blood of experiment group were higher than those in control group, and there were significant differences between these two groups on the third, seventh and fourteenth day(P<0.05 or P<0.01). Conclusion ICAM-1 can inhibit the up-regulation of peripheral blood somatic stem cells after acute myocardial infarction in rats.

Select patients diagnosed of hypertension in the first place in 16 hospitals and the patients were described by association rules analysis and distribution for the analysis in the study,in order to understand the information of diagnosis and treatment in hypertension patients in real world. The information include age, gender, admission condition, inpatient department, hospitalization expenses, western medicine comorbidities, the traditional Chinese medicine (TCM) syndrome and the medicine. The average age of patients was 64 years in the study. The proportion of men to women about 1. 10: 1. Admission condition is critical for about 10.12% of the total and more concentrated in the cardiovascular department. Hospital stay ranged from 8 to 14 d. Inpatients with medical insurance is 62.93%. Total hospitalization cost distribution most is the 5 000-10 000 RMB. Hypertension complicated with coronary heart disease, blood lipoprotein disorder disease; phlegm and blood stasis and Yin deficiency of liver and kidney are the most in TCM syndrome type. Promoting blood circulation and removing blood stasis is the major in Chinese medicine treatment. Western medicine treatment basically conforms to the guidelines. The most antihypertensive drugs is calcium antagonistst, accounting for about 81.2% of the total number. Class ACEI, class ARB, beta blockers, diuretics class are accounted for 43.0%, 43.4%, 42.4%, 42.4%, fixed compound is only 2 393, accounting for about 8%. the total frequency of five classes of antihypertensive drugs is 78 206 times. The principal conclusions of this analysis are as follows: the elderly people is the most in hypertension, more men than women; medical insurance is the majority type in hospitalization cost; nearly half of the population is combined with coronary heart disease; phlegm and blood stasis and yin deficiency of liver and kidney are the most in TCM syndrome type; western medicine treatment basically conforms to the guidelines. Combination therapy is more, less fixed compound preparation in western medicine. Chinese medicine is mainly to promoting blood circulation. Suggesting that the clinical treatment in strict blood pressure and at the same time, pay attention to combination therapy and the use of fixed compound preparation,it's useful to control the blood pressure better. Combined with traditional Chinese medicine and resolving phlegm and removing blood stasis, reduce the target organ damage, reduce complications, the prevention and control work of hypertension in China still faces enormous challenges at present. The result provides reference information for clinical medicine and medical research.
