Objective To evaluate retrospectively ECG -gating for the coronary angiography with MSCT. Methods 15 patients were studied with a multislice spiral CT on retrospective ECG -gating,0.5s rotation, and cardial segment reconstruction algorithm. Nine phases were chosen to reconstruct images of coronary arteries. Results In the 230 coronary artery segments,213 (91%)were best visualized at 70%. And 15 (6.4%), 9 (3.8%), and 3 (1.3%) were optimal at 80%, 40% , and 5% of the cycle respectively. Conclusion The coronary arteries usually are best visualized at 70% image reconstruction window of the cardial cycle.

0.05). Oil red O staining demonstrated that lipid droplet number was significantly less in the each adipogenic inductor + extracting solution from Eucommia ulmoides Oliv. groups compared with the adipogenic inductor group. CONCLUSION: Extracting solution from Eucommia ulmoides Oliv. can induce the differentiation of in vitro cultured goat BMSCs into osteoblasts, and inhibit their differentiation into adipocytes.

OBJECTIVE To determine the association between phenotype and genotype of biofilm in Staphylococcus.METHODS All 156 clinical isolates of coagulase negative Staphylococcus(CNS) and 90 S.aureus(SAU) strains isolating from clinical specimens from Mar 2005 to Jul 2008,as well as 12 CNS strains from nasal swabs of healthy carriers from hospital staff,were collected.Congo red technique was performed to examine slime production.The presence of the intercellular adhesion genes(icaA and icaD) was determined by the polymerase chain reaction method.The phenotype and genotype of biofilm were analyzed.RESULTS Thirty-two out of 168 CNS isolates were biofilm producers(19.0%) while 32 out of 90 SAU isolates were producers(35.6%).All strains positive for icaA positive were also positive for icaD.The 16 strains(10 CNS isolates and 6 SAU isolates) were icaA and icaD positive but do not produced slime.CONCLUSIONS For SAU,the percentage of slime-production strains(35.6%) is higher than that found in CNS(19.0%).The characteristic of biofilm-negative variants having the ica loci might contribute to the dissemination.For clinical isolates of S.epidermidis,ica locus may not be a significant marker discriminating between invasive and contaminating isolates.

Exertional heat stroke (EHS) is an emergency with a high mortality rate, characterized by acute onset and identification difficulties. EHS prevention focuses on evaluating the environment by professionals, making preventive measures in advance, identifying internal and external risk factors for the onset of disease, carrying out prior heat adaptation and endurance training, monitoring the status of high risk persons in real time. After occurrence of EHS, the key to success treatment is on-site accurate identification and diagnosis and rapid implementation of effective cooling measures, thus winning time of EHS patients transferred to the hospital for the treatment. This article reviews the current status of EHS prevention and treatment in domestic and foreign from the scene to the hospital. Summarizing the recognition, diagnosis, cooling measures, treatment concepts and principles of EHS, we hope to provide a reference for the rescue of EHS in hospital and outside.

Objective To find out whether inpatients with acute ischaemic stroke and atrial fibrillation (AF) have higher rate of renal dysfunction than without AF,and analyze risk factors associated with renal dysfunction.Method 374 patients with acute ischaemic stroke and AF were enrolled,which cases have complete data.500 patients were randomly selected as the non-AF group.To compare the prevalence of renal dysfunction [eGFR ＜ 60 mL/(min· 1.73 m2)] of two groups.Non-conditional Logistic regression analysis was used to detemmine the factors associated with renal dysfunction.Results 374 patients in AF group,114 (30.5％) were renal dysfunction;500 patients in non-AF group,75 (15％) were renal dysfunction (P =0.000,OR =2.485).The eGFR of AF and non-AF group was (77.75 ± 39.89) mL/(min· 1.73 m2) and (96.93±39.14) mL/(min · 1.73 m2).In Logis tic regression analysis,heart dysfunction (OR =2.057),hypertension (OR =1.826),diabetes (OR =1.897),hypevuricemia (OR =3.161) were found to be associated with renal dysfunction.Conclusions Adult patients with acute ischaemic stroke and AF have a higher rate of renal dysfunction than acute ischaemic stroke without AF.Heart dysfunction,hypertension,diabetes,hyperuricemia were factors associated with renal dysfunction.

BACKGROUND: Serum levels of high-sensitivity C-reactive protein (hs-CRP) can be used to predict cardiovascular injury.OBJECTIVE: To investigate the serum levels of hs-CRP in a rabbit model of atherosclerosis following repeated long-termexposure to positive acceleration and to predict the risk of cardiovascular injury.METHODS: Twenty-four New Zealand purebred rabbits were randomly divided into a positive acceleration group and a controlgroup. Rabbits in the positive acceleration group were exposed to +4 g rotation for 20 seconds with an acceleration of 1 g/s. Therotation interval was 5 minutes and totally three rotations were daily performed for 3 days per week. 0.5 g rotation was addedevery week, and by week 4, +6 g rotation was added, and the exposure lasted for 40 seconds.RESULTS AND CONCLUSION: Exposure to positive acceleration yielded significant effects on serum level of hs-CRP in rabbitswith atherosclerosis compared with before exposure (P < 0.01), but exposure time did not produce effects on serum level ofhs-CRP (P > 0.05). The interaction between exposure to positive acceleration and exposure time also did not produce significanteffects on serum level of hs-CRP (P > 0.05). Hyperplastic foam cells in the aortic tunica intima and the superficial layer of mediaincreased with the prolongation of exposure to positive acceleration. Repeated long-term exposure to positive acceleration maylead to a long-term high serum level of hs-CRP in rabbits.

The present study was to investigate whether peripheral NMDA receptors were involved in the persistent nociceptioninduced by subcutaneous (s. C. ) bee venom injection in the conscious rat by using quatitative pain scoring methods, a.c. Bee venom injection into one hindpaw resulted in a persistent, monophasic nociceptive response characterized by continuously flinching.lifting and licking the injected paw for more than I h. The non-competitive. NMDA receptor channel blockers, ketamine and ME-801, were administered s.c. 5 or 20 min after bee venom. Local ketamine injection produced a suppression of flinching reflex by 20. 90±2.88% and 45.76±13.9%, while that of lifting/bcking time by 39. 53±10. 05% and 59.94±5.53%, at doses of 25mmol/L and 50 mmol/L respectively without any motor disturbance, Local MK-801 resulted in an inhibition of flinching reflexby 22.84±3.12% and 49.53±5.35%. While that of lifting/licking time by 17. 49±5.67%and 53.49±3. 87%. At doses of 10μmol/L and 100 ,μmol/L respectively also with no motor disturbance. However, s. C. Administration of ketamine and MK-801 inior region symmetrical to the bee venom injection site on the contralateral hindpaw produced no change in the nociceptive behaviors, suggesting that the analgesic actions of keramme and MK-8Ol were not the result of systemic effects. The present resultsuggests that peripheral NMDA receptors are involved in the production of persistent pain.
