AIM: To observe the effects and safety of clopidogrel used in percutanous coronary intervention (PCI) while acute occlusions of coronary arteries happened. METHODS: 92 patients with acute occlusions of coronary arteries were treated through PCI and they were randomized equally into following groups: clopidogrel group (CPG group) and ticlopidine group (TCP group). Each patient was treated with clopidogrel 25 mg bid or ticlopidine 250 mg bid for 4 weeks after PCI. RESULTS: Compared with the control group, there was not significantly difference in platelet aggregation ( 45.36 ? 2.98 vs 51.60 ? 2.56 ) and clinical effects ( 97.95 % vs 93.02 %) after 3 weeks. The proportion of patients with adverse events who had to release the treatment was 2.04 % (CPG group) and 16.27 % (TCP group). CONCLUSION: The clinical effect of clopidogrel is similar to ticlopidine and shows less adverse events.

Objective To understand the causes and the ratio of cause constituents in children with chronic cough in Beijing. Methods Patients with chronic cough treated at respiratory clinic of the Children' s Hospital Affiliated to Capital Institute of Pediatrics from May 2009 to April 2011 were included in this study. Etiologic diagnostic procedure suggested for children by the Subspecialty Group of Respiratory Diseases,the Society of Pediatrics,Chinese Medical Association in 2008 was implemented to manage the patients. After three - month follow - up,the etiological data was analyzed. Results Totally 213 patients with chronic cough aged 1. 1 to 14. 0 years old were enrolled,inclu-ding 40 cases(18. 8% )aged≤3 years old,134 cases(62. 9% )aged ﹥ 3 to 6 years old,and 39 cases(18. 3% ) aged ﹥ 6 years old. The majority of patients with positive allergen tests were sensitized to inhaled allergens. One child had positive result in 24 - hour esophageal pH monitoring,but his cough didn't respond well to the specific treatment for gastroesophageal reflux,so he wasn't diagnosed as gastroesophageal reflux cough. The 4 leading causes of the 213 pa-tients with chronic cough were cough variant asthma(CVA)in 92 cases(43. 2% ),CVA associated with upper airway cough syndrome(UACS)in 57 cases(26. 8% ),UACS in 28 cases(13. 2% ),respiratory infection and post - infec-tion cough(PIC)in 26 cases(12. 2% ),while other causes were found in 8 cases(3. 7% ),and unknown etiology in 2 cases(0. 9% ). The incidence of CVA ranked top 1 in all the 3 age groups,followed by PIC in ≤3 years old group, while CVA associated with UACS in the other 2 age groups. Conclusions CVA,CVA associated with UACS,UACS and PIC were the 4 leading causes for children with chronic cough in Beijing. Children in different age groups had dif-ferent constituents ratio of causes of chronic cough.

Objective:To obtain some effective objective markers used to predict the early liver metastasis of colorectal tumor,the relationship of liver metastasis of colorectal tumor with associate detection three markers such as CK20mRNA、CD44V6 and PCNA was studied. Methods:The expression of CK20mRNA in portal venous blood from 30 colorectal cancer patients was detected by fluorescent quarto RT-PCR,and the results of CD44V6 and PCNA in colorectal cancer tissue were determined by means of immunohistochemistry, and then compared with control groups through statistics analysis. Results:The rate of positive expression of CK20mRNA in colorectal cancer patients' portal venous blood was obviously superior to the level of benign pathological changes controls(P

Objective To use mouse astrocytes elevated gene‐1 (AEG‐1) monoclonal fluorescent antibody for detecting tumor cells in malignant serous cavity effusions .Methods The expression of AEG‐1 in serous cavity effusion exfoliated cells by PCR and Western‐blot ;the mouse monoclonal anti‐AEG‐1 fluorescent antibody and tumor cells in malignant serous cavity effusions were co ‐incubated ,meanwhile ,the serous cavity effusions in benign lesions were taken as the negative control .Results The AEG‐1 expres‐sion was positive in malignant serous cavity effusions exfoliated cells ,while which in benign lesion serous cavity effusion was nega‐tive or weakly positive ;meanwhile the results of direct labelling in mouse anti AEG‐1 monoclonal antibodies were consistent with the results by PCR and Western‐blot .Conclusion Mouse anti AEG‐1 monoclonal fluorescence antibody can provide certain theoret‐ical basis for the detection of tumor cells in serous cavity effusion .

Objective To investigate the relationship between Pin1 and CyclinD1 expression and the development of gastrointestinal stromal tu?mor(GIST). Methods The protein and mRNA expression of Pin1 and CyclinD1 in 85 samples of GIST and adjacent non?cancerous tissues were detected by immunohistochemistry and real?time quantitative polymerase chain reaction. Results The expression rate of Pin1 protein in GIST tis?sues(64.7%;55/85)was higher than that in adjacent non?cancerous tissues(26.7%;4/15). Similarly,the expression rate of CyclinD1 protein in GIST tissues(42.3%;36/85)was higher than that in adjacent non?cancerous tissues(6.7%;1/15). The expression of Pin1 and CyclinD1 mRNA in GIST tissues was 7.03 and 5.53 times that in adjacent non?cancerous tissues ,respectively. There was no obvious correlation between the expres?sion of Pin1 and clinicopathological parameters. The expression of CyclinD1 was positively correlated with the grade of NIH and tumor diameter (P<0.05). There was a significant correlation between the expression of Pin1 and CyclinD1 in GIST tissues. Conclusion The expression of both Pin1 and CyclinD1 was up?regulated in GIST tissues. The significant correlation between the expression of Pin1 and CyclinD1 in GIST tissues sug?gests that their synergistic effect promotes carcinogenesis and the development of GIST.
