BACKGROUND: The clinical effect of drug-eluting stent implantation in treatment of coronary artery disease is good, but there may be some differences in the therapeutic effect between different stents. OBJECTIVE:To compare the clinical effect of different stent implantation in treatment of coronary artery disease. METHODS:A total of 278 patients with coronary artery disease were enroled and al underwent coronary artery stent implantation treatment, of which 91 patients underwent implanted rapamycin eluting stent, 92 patients underwent implanted paclitaxel eluting stent, and 95 patients underwent implanted bare metal stents. Al the patients were folowed up for 12 months after stents implantation. The occurrence of adverse cardiac events such as death, myocardial infarction, and the occurrence of coronary restenosis and host reaction were recorded. RESULTS AND CONCLUSION:The rates of coronary artery stenosis, acute myocardial infarction, coronary artery bypass grafting or second-time percutaneous coronary interventional therapy in the paclitaxel eluting stent and rapamycin eluting stent groups were al lower than those in the bare metal stent group (P< 0.05). There were no significant differences in the above indicators between paclitaxel eluting stent and rapamycin eluting stent groups (P> 0.05). There was no significant difference in the mortality between these three groups (P> 0.05). There was no stent shift, shedding, breakage, bad implantation position, leukocytosis, thrombocytopenia and hemolysis in these three groups. These results demonstrate that the therapeutic effects of these two kinds of drug-eluting stents are al good enough, and better than those of bare metal stents.

Objective To discuss the anxiety and panic disorder in the patients with cardiovascular diseases. Method To analyze the incidental rate, diagnostic criteria, clinical manifestations and treatment in the anxiety and panic disorders with cardiovascular diseases. Result The incidental rate of anxiety and panic attack in the patients with cardiovascular diseases is high. The common clinical manifestation including chest pain, hypertension, tachycardia, arrhythmia and symptoms similar with left heart failure. Conclusion Physicians ought to improve their ability in identifying the anxiety and panic disorders with cardiovascular diseases.

Objective To observe the effects of mesenchymal stem cells (MSCs)injection from tail-vein on the expression of glial cell line derived neurotrophic factor (GDNF) after the spinal cord injury (SCI) of rats.MethodMSCs were cultured from the thighbone of adult wistar rats.The T10 level spinal cord injury was execute by the modify-Allen's device. The MSCs labeled by bromodeoxyuridine were transplanted into the vein of tail by injection immediately after spinal cord injury. Adult Wistar rats were randomly divided into three groups: SCI cured with MSCs transplantation (group A), SCI received normal saline(group B),and control group (group C). Then MSCs were detected and the expressions of GDNF of the lesion and neighbor areas were examined by Reversetranscription polymerase chain reaction (RT-PCR) and immunohistochemistry.ResultImmunohistochemistry: MSCs labeled by bromodeoxyuridine could be detected in the injuried spinal cord after transplantation. It was located at the nucleolus of MSCs. The cells survived and migrated rostrallyand caudally from the injection sites. With the time passed, the number of MSCs labeled with bromodeoxyuridine was decreased. RT-PCR: The expression of Group A was increased on the followed day, and the expression of Group B was increased on the 1st day but decrease from the 5th day then on.compared with group B, transplantation of MSCs significantly enhanced the expression of GDNF mRNA than group A on the 1st, 3rd, 5th day after cell transplantation(P

Objective To evaluate the value of color Doppler flow imaging(CDFI) in the diagnosis of congenital coronary artery fistula (CAF).Methods Thirteen consecutive patients ranging in age from 8 to 68 years underwent conventional transthoracic echocardiography,which depicts their origin, course, and drainage site. Results Right CAFs were detected in 8 patients: four of them had drainages to the left ventricle, two to the main pulmonary artery, one to the right ventricle(RV) and the other to the right atrium(RA). CAFs arising from the left coronary artery were noted in five patients: three of them had drainages to the main pulmonary, and the other two to the RA and RV respectively. The origin and the course were precisely defined and the drainage site was clearly depicted in all thinteen patients. The diagnosis of the thirteen patients was confirmed by coronary angiography, and eight of them received surgical treatment. Conclusions CDFI offers a simple, useful and reliable technique in diagnosis of CAF.

Objective To evaluate the screening effect of OSTA in Chinese post-menopausal women, to provide suggestions for the further development of OP screening in mainland China. Methods With the data from Chinese Database of Bone Mineral Density of Chinese women aged 50 years old and above, each subject was calculated a OSTA score by the formula of OSTA and classified into three risk levels (the normal, the osteopenia and the osteoporosis) or two groups (the low and the high risk) by the original cutoffs, and compared with results by T-score. A series of screening indexes, such as sensitivity, specificity, kappa value and ROC etc., were employed to compare and analyze the diagnosis results of OSTA with T-score from the femoral neck bone density. Results According to the 3 levels by original cutoffs, the Kappa value was 0.357 (P

Objective To explore the surgical treatment of advanced rectal carcinoma in aged people. Methods The clinical data of 65 aged patients with advanced rectal carcinoma from 2000 to 2004 were analyzed retrospectively. Results All cases were Dukes D stage or accompanied with hepatic metastasis. Hartmann's operation was performed in 26 cases, single lumen sigmoidostomy in 11 cases, double lumen sigmoidostomy in 11 cases and resection of hepatic metastatic cancer in 12 cases. Rectal upper arterial catheter chemotherapy was performed in 19 cases and hepatic arterial catheter chemotherapy in 15 cases. The 3-year survival rate of Hartmann's operation was 34%(9/26), and the average survival time was 20?3.17 months in the patients underwent rectal upper and hepatic arterial catheter chemotherapy, and 10?1.77 months in the patients who could not be treated surgically(P

Objective To evaluate the characteristics of leptomeningeal metastasis of gliomas on magnetic resonance(MR) imaging and to provide evidence for clinical early diagnosis and treatment.Methods Twenty-one cases of intracranial gliomas with leptomeningeal metastases were scanned with conventional spin echo(SE) and fast spin echo(TSE),8 cases with fluid attenuated inversion recovery(FLAIR),and all of cases were operated with enhancement.Results ⑴ With MR plain scan,18 cases revealed vary range of distortion and illegibility structure of cerebral cistern and sulcus,and 6 cases revealed the asymmetrical enhancement of the wall of ventricle.Eleven meningeal neoplasms nodes were found in subarachnoid space in 7 cases,and some of the appearances could be seen in several cases.Eight cases of them were added with FLAIR,and the neoplasms nodes were showed more clearly and higher signal than TSE-T2W imaging.⑵ With MR enhancement,all cases with encephalic gliomas showed obvious enhancement with vary features of the enhancement of leptomeningeal metastasis,including tail sign(5/21),line sign(10/21),strip sign(3/21),node sign(7/21) and a few of cases included two signs.Conclusion It was very important for clinician to improve the cognition of MR imaging characteristics of leptomeningeal metastases of glioma,and to choose the proper MR imaging scan technique to increase the detection rate of early meningeal diseases.
