Antiplatelet therapy and stent implantation have been the dominant treatment to reduce the mortality of patients with coronary artery disease.Recently,studies have showed that adverse cardiac events still occur in part of patients with coronary artery disease after the antiplatelet treatment with aspirin and/or clopidogrel.Thus,resistance to aspirin and clopidogrel has attracted increasing attention.It will be great benefit to these patients who were identified resistance and made tailoring antiplatelet therapy So far many platelet function tests has been used in clinical to monitor the reaction of the antiplatelet drugs for prevention and treatment of thrombosis in patients with coronary artery disease.These monitoring tests may be chosen based on different antiplatelet drugs including aspirin,clopidogrel and GP Ⅱ b/Ⅲ a antagonist.The results of antiplatelet drug resistance may be different due to different platelet function methods,thus the related clinical adverse events needs further verification.

Objective To observe the changes of serum lipids ,hs‐CRP ,MFG‐E8 and Klotho gene levels after rosuvatatin treatment in elderly patients with coronary heart disease complicating hyperlipidemia for investigating the action mechanisms of ro‐suvatatin and its application value .Methods Totally 129 elderly patients with coronary artery disease complicating hyperlipidemia in our hospital were randomly divided into two groups .The control group received only conventional treatment ,while on this basis the rosuvatatin group was given rosuvastatin 10 mg everyday ,with 2 months as a treatment cycle .Blood lipids ,hs‐CRP ,MFG‐E8 and Klotho gene levels before and after treatment were compared between the two groups .The regulation effect of rosuvatatin was investigated Results The blood lipod ,hs‐CRP ,MFG‐E8 and Klotho before treatment had no obvious difference between the two groups .The levels of TC ,LDL‐C and TG after treatment in the rosuvatatin group were significantly decreased compared with the control group ,while the HDL‐C level was significantly increased ,the differences were statistically significant (P<0 .05) .In addi‐tion ,the hs‐CRP level after treatment in the rosuvatatin group was significantly lower than that in the control group (P<0 .05) . Compared with the control group ,the levels of MFG‐E8 and Klotho after treatment in the rosuvatatin group were increased ,the difference was statistically significant (P<0 .05) .Conclusion Rosuvastatin could decrease the blood lipid and hs‐CRP levels ,up‐regulates the MFG‐E8 and Klotho levels ,alleviates the inflammatory reaction and has the anti‐vascular aging effect ,thus effectively treats the patients with coronary heart disease complicating hyperlipidemia .

Objective To investigate the diagnosis value of 128-slice spiral CT in patients with adult intussusception. Methods Direct features of 128-slice spiral CT of 63 adult intussusception patients confirmed by operation and pathology were analyzed retrospectively. Results In 63 cases of intussusceptions, 1 case had idiopathic intussusception, and the other 62 cases had secondary intussusception (1 case with multiple intussusceptions). Direct signs included:target signin 60 cases,double intestines signin 59 cases,blood vessel curling signin 56 cases, andcomet-tail signandkidney signin 51 cases. Lipoma was the most common benign lesions of intussusception, and colon cancer was the most common malignant lesions of intussusception. Conclusions The 128-slice spiral CT combined with multiple plane restructuring has the important value in diagnosing adult intussusception.

Objective To investigate the clinical features of young female patients with acute myocardial infarction (AMI) who were referred to Peking Union Medical College Hospital. Methods A total of 24 consecutive AMI female patients (age≤44 years) who underwent coronary angiography were retrospectively retrieved from the database, and 70 AMI patients whose age ≥ 65 years and who also underwent coronary angiography were enrolled as a control (elderly) group. Clinical features were compared between the two groups. Results Of the 24 young female AMI patients, MI from non-atherosclerosis was identiifed in 9 patients (non-ATS group). Compared to the remaining 15 young female AMI patients (ATS-group), non-ATS group was younger (P<0.05), with lower BMI (P<0.05) and less traditional risk factors of coronary heart disease (P<0.05). Coronary angiography showed more normal artery (P<0.05) and lesions on left main (P<0.05). However, when compared to the elderly group, the young female ATS-group was associated with less hypertension (P<0.01), smoking (P<0.05), traditional risk factors (P<0.01) and lower level of blood pressure (P<0.05), fasting glucose (P<0.05), serum creatine (P<0.01), TC (P<0.05), and LDL-C (P<0.01) at admission. Coronary angiography showed single vessel disease was the most common lesion. Conclusions Acute myocardial infarction in young female might be caused by non-atherosclerosis. Those due to atherosclerosis differ in coronary risk factors and angiographic features from the elderly female AMI patients.

The purpose of this study was to investigate the changes of protein kinase Calpha (PKCalpha) and cyclin D1 expressions in pulmonary arteries from smokers with normal lung function and smokers with mild to moderate chronic obstructive pulmonary disease (COPD). The peripheral lung tissues were obtained from 10 non-smokers with normal lung function (non-smoker group), 14 smokers with normal lung function (smoker group), 11 smokers with mild to moderate COPD (COPD group). The morphological changes of pulmonary arteries were observed by HE-staining. The expressions of alpha-smooth muscle actin (alpha-SMA), proliferating cell nuclear antigen (PCNA), PKCalpha and cyclin D1 proteins in pulmonary artery smooth muscle cells (PASMCs) were immunohistochemically determined. The percentages of PCNA-positive cells were taken as the smooth muscle cells proliferation index (PI). The mRNA expressions of PKCalpha and cyclin D1 in PASMCs were evaluated by real-time fluorescence PCR. Morphometrical analysis showed that the ratio of pulmonary artery wall area to total area (WA%) in smoker group and COPD group was significantly greater than that in non-smoker group (P<0.01). The PASMCs proliferation index in smoker group and COPD group was significantly higher than that in nonsmoker group (P<0.01). The protein levels of PKCalpha and cyclin D1 in PASMCs were significantly increased in smoker group and COPD group as compared with non-smoker group (P<0.01). The mRNA expressions of PKCalpha and cyclin D1 in PASMCs were significantly elevated in smoker group and COPD group as compared with non-smoker group (P<0.01). Significant correlations were found between PKCalpha protein and WA% or PI (P<0.01). Correlations between cyclin D1 protein and WA% or PI also existed (P<0.01). The expression of PKCalpha was positively correlated with the expression of cyclin D1 at both protein and mRNA levels (P<0.01). In conclusion, increased expressions of PKCalpha and cyclin D1 might be involved in the pathogenesis of abnormal proliferation of PASMCs in smokers with normal lung function and smokers with mild to moderate COPD.
