Chinese Medical Ethics 1995;0(02):-
With the development of society and medical science,the medical arena should develop with the times,transform medical ethics idea, construct new medical ethics view to unceasingly promote the medical ethics progress and the comprehensive,coordinated, and sustainable development of medical industry.This article discussed the principle,significance and several related problems of new medical ethics view in order to make direct instruction for the constnuction of new medical ethics view.
2.Mechanisms of vascular vertigo triggered by vertebral artery dominance
International Journal of Cerebrovascular Diseases 2011;19(11):876-880
Vascular vertigo is a common vertigo.Vertebral artery dominance is a vascular phenomenon,and its mechanism remains unclear.It causes basilar artery changes and hemodynamic changes in posterior circulation.Vertebral artery dominance may trigger vascular vertigo through a variety of mechanisms.

Objective To conduct the global assessment of methylated DNA status of CpG islands. Methods The modified AIMS (amplification of inter-methylated sites) technology was adopted, which mainly included 3 groups of isoschizomers (methylation-sensitive and methylation-insensitive restricted enzymes). The comparison analysis of methylome among 3 concentrations (6%, 8%, 10%) of polyacrylamide with 8M urea denaturing sequencing gel and the digestion effect among 3 groups of isoschizomers were carried out. The results of personal molecular imager FX system and autoradiography were also compared. Results Genome-wide detection of methylome of CpG islands might be the technical basis for the subsequent analysis. The resolving power and scope bands in 6% polyacrylamide denaturing sequencing gel were superior to those in gels with the other two concentrations. 3 groups of isoschizomers could meet the need of genome-wide detection of methylome of CpG islands. Personal molecular imager FX system and autoradiography could be used together, and they compensated each other. Conclusions The optimized AIMS technology is a kind of high-throughput method to analyze methylome, which is simple, specific, and easy to handle. The 3 groups of isoschizomers can cover most of CpG islands for genome-wide detection and get the ideal results. Only a small quantity of genome DNA is enough to meet the need of clinical detection.

Objective To study the interventional therapeutic methods in Budd Chiari syndrome (BCS) complicated with thrombosis. Methods Eighteen patients of BCS complicated with thrombosis, including 2 cases of hepatic vein (HV) occlusion and 16 cases of inferior vena cava (IVC) occlusion, were treated. Therapeutic methods were anti coagulation with Co Danshen and aspirin in 10 cases or the anti coagulation and thrombolysis with urokinase in 8 cases before operation, treatment with PTA and stent during operation,and thrombolysis with urokinase and the anti coagulation after operation. Results Technical success was achieved in all patients without serious complications. The mean blood pressure in IVC dropped from (31 82?0 52)cm H 2O(1 cm H 2O= 0 098 kPa) to (18 17?0 38)cm H 2O immediately after the procedure. The blood pressure in HV dropped from 42 cm H 2O and 41 cm H 2O to 15 cm H 2O and 16 cm H 2O, respectively. All 18 cases were followed up for an average of 38 months (range 6-72 months). The main symptoms and signs completely disappeared in 12 cases and partially alleviated in 6 cases. Conclusion The interventional treatment of BCS complicated with thrombosis was a safe and effective method.

Basilar artery hypoplasia (BAH) has been paid less attention to in the past.However,the increased detection rate makes the clinical significance of BAH to be gradually recognized.BAH have interaction with vascular risk factors,and this may promote the occurrence of ischemic events in posterior circulation.Brain evoked potential can be used as an important means for early detection of this pathophysiological events.The depth study of pathological significance of BAH helps to deepen the understanding of the mechanisms of posterior circulation ischemic events.

A prospective study was performed to evaluate the diagnostic value of B- mode ultrasonography and inferior vena cavograme and the value of PTA in Budd-Chiari syndrome.One hundred sixty-eight cases including ninety-two men and seventy-six women, age ranged 11~63(mean,34.8 years).Among them 65 were treated with PTA or stent placement.The authors gave a minute and detail description of clinical feature,ultrasono- graphy,inferior vena cava or hepatic venogram,CT and other radiologic demonstration of Budd-Chiari syndrome retrospectively.Four types of Budd-Chiari syndrome were demon- strated based on anatomy,B-mode ultrasonography,inferior vena cavogram and hepa- tovenograme.(1)IVC membranous webs(76 subjects,45.2%),(2)IVC segmental stenosis or occlusion(65 subjects,38.7%),(3)hepatic vein occlusion(10 subjects,6. 1%),(4)mixed type(17 subjects,10%).The treatment of the Budd-Chiari syndrome with percutaneous transluminal balloon dilatation and stent placememnt of inferior vena cava or hepatic vein was safe and satisfied.Its long-term effectiveness(follow up 3-5 years)is al- so satisfactory.

0 05).Conclusion The distribution frequency of bb type of VDR genotypes in Han populations of China was more prevalent,followed by Bb and bb types in turn.In the patients receiving long term glucocorticoid therapy,there is no significant difference in BMD between Bb and BB genotypes.The data suggest that the VDR genotypes may not be a means to identify patients at great risk of glucocorticoid induced osteoporosis,which await to be further confirmed with a large sample size.
