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 analyze the clinical characteristics of Mycoplasma pneumoniae pneumonia in children under 2 years old. Methods The clinical features and treatment outcomes were analyzed in 57 children under 2 years old and compared with 153 children more than 2 years old. Results Compared with children more than 2 years old, in children under 2 years old, the number of cases with fever was fewer, the fever peak was lower and the lasting time was shorter. However, in children under 2 years old, the severe pulmonary signs were more common, the incidence of wheeze was higher, meanwhile, the count of white blood cells (WBCs) was signiifcantly increased, more small pieces of lfuff shadow was showed on chest X-ray, and the pulmo-nary complications were fewer, less corticosteroid was needed for treatment. After one-week therapy, the chest X-ray shadows were disappeared in most of children. Complications out of lungs, such as rash, liver function damage and cardiac damage can be found in both groups and no signiifcant difference (P>0.05). Conclusions Mycoplasma pneumoniae pneumonia in children under 2 years old had the characteristics of mild symptoms, severe pulmonary signs, few pulmonary complications, light systemic inlfammations and mild radiological changes.

OBJECTIVE: To observe the preventive and therapeutic effects of Yishen Huanji Decoction (YSHJD), a compound traditional Chinese herbal medicine, on military overtraining-induced kidney injury in a rat model. METHODS: Thirty SD rats were randomly divided into normal control group, untreated group and YSHJD-treated group. The military overtraining-induced kidney injury in rats was established by forcing to run on the treadmill for 8 weeks. The rats in YSHJD-treated group were administered with YSHJD at the same time. The 24-hour urines were collected every weekend for detecting the contents of urinary sediment, 24-hour urine total protein, 24-hour urine albumin and activity of N-acetyl-beta-D-glucosaminidase (NAG). The blood and renal tissues were collected after 8-week training, and the levels of serum urea nitrogen (BUN) and creatinine (SCr) were detected. Angiotensin II (Ang II) was detected by radioimmunoassay and activity of Na(+), K(+)-ATPase in kidney was analyzed by chemical colorimetric method. RESULTS: Compared with the normal control group, after 8-week training, the contents of 24-hour urine protein, activities of NAG in urine, and the levels of BUN and SCr in rats in the untreated group and YSHJD-treated group were obviously increased (P<0.05), and these parameters of the YSHJD-treated group were lower than those of the untreated group (P<0.05). The contents of Ang II in blood plasma and kidney of rats in the untreated group and YSHJD-treated group were higher than those of the normal control group (P<0.05), and had no statistical difference between the untreated group and YSHJD-treated group. Compared with the normal control group, the activity of Na(+), K(+)-ATPase in kidney of rats in the untreated group was obviously decreased (P<0.05), and had no statistical difference between the normal control group and YSHJD-treated group. CONCLUSION: YSHJD can protect against military overtraining-induced kidney injury in rats by decreasing the contents of 24-hour urine protein, BUN and SCr, and the activity of NAG, and increasing the activity of Na(+), K(+)-ATPase.

Objective To determine the genetic subtypes and susceptible population of Cryptoccocus neoformans in China. Methods We analyzed 129 strains of Cryptococcus neoformans isolated during the period from 1980 through 2006 in 18 Prov-inces and municipalities of central and eastern China using epidemiological method,PCR fingerprint,and multilocus sequence typing (MLST).Results About 71.5% (91/129)of the clinical strains were isolated from the patients without any recognizable immunodeficiency.Only 8.5% (11/129)of the strains were from AIDS patients.The remaining 20.9% (27/129)were from patients with underlying diseases other than HIV infection.Furthermore,PCR fingerprinting and MLST showed that serotype A strains exhibited a unique VNⅠsubtype,which was distinguishable from the reference VNⅠmolecular types.For convenience we named this unique genotype as VNⅠc.Conclusions People without any recognizable immunodeficiency are the main susceptible population of the 129 clinical strains of Cryptococcus neoformans ,which contrasts with the reports from other countries.The different genetic subtypes of Cryptococcus neoformans between China and other countries may contribute to such a difference.

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.

To study the effects of 70%Hepatectomy on the proliferation of rat fetal hepatocytes after intrasplenical transplantation, fetal hepatocytes isolated from 3 week SD rat fetuses bred were transplanted into the spleens of liver regeneration model rats with 70% partial hepatectomy. The cell cycle of hepatocytes in the remanent liver was analyzed by flow cytometer and the density dimensions of the donor fetal hepatocytes in spleen were measured by Image Analysis System 7 and 30 days post transplantation respectively. Compared with the control group, the proportions of S state cells in the remanent liver were obviously increased ( P
