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.

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.

To investigate the correlation of apolipoprotein E (ApoE) gene polymorphism and atherosclerotic cerebral infarction (ACI).Methods Polymerase chain reaction-restricted fragments length polymorphism (PCR- RFLP) was used to determine ApoE genotype on 92 cases with ACI (42 cases

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.

Two patients of Budd-Chiari syndrome,suffering from the anemalons drainage of inferior vena cava into left atrium were reported including one male of 41 years old and female of 42. togectll with labial cyanosis,fingers and toes symptoms of portal hypertension and IVC hypertension. The obstruction of IVC wastreated with balloon catheter hypertension and IVC hypertension the disrotreaed also after PTA.The echo wasn't discovered with Dopple ultrasound after PTA.

Large artery intracranial occlusive disease is a important and common vascular lesion type.It is closcly associated with the onset and recurrence of ischemic stroke; however,at present there are many inadequacies in the study of its etiology and treatment.This article mainly reviews the understanding process of the large artery intracranial occlusive disease,present research results and problems need to be solved.

With the development of neuroimaging the detection rate of basilar artery tortuosity is significantly high.The occurrence and development processes of basilar artery tortuosity are affected by age,basilar artery length,vertebral artery dominance,and other factors.Basilar artery tortuosity may influence the blood supply of posterior circulation and cause brainstem and cranial nerve pressure leading to clinical symptoms.

BACKGROUND:With the development of the research, induced pluripotent stem cel s are applied to the build of disease model, drug screening, regenerative medicine, and many other research fields, and have made significant achievements, especial y in the study of nervous system diseases.
OBJECTIVE:To summarize the recent development of induced pluripotent stem cel s and to raise problems and prospects based on the latest research in this field.
METHODS:The first author searched the PubMed database for articles about the induced pluripotent stem cel s, including reviews, clinical research and basic research, published from January 2006 to September 2014. The keywords were“iPS, induced pluripotent stem cel”, and final y 60 articles were included in result analysis.
RESULTS AND CONCLUSION:Induced pluripotent stem cel research continues to make breakthrough from its discovery by Yamanaka’s team in 2006 to winning Nobel Prize in 2012. Induced pluripotent stem cel research has broad prospects in the disease model construction, drug screening and regenerative medicine. Currently, problems such as reprogramming methods, cel stability, and clinical transformation stil need to be solved, and further researches are necessary.

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.

BACKGROUND:The long-term contraction of skeletal muscle can lead to the decrease of resting potential, affect its contraction, and result in the occurrence of fatigue. Whether acupuncture and injury-free magnetic lifting needle are effective on the recovery of resting potential? OBJECTIVE: To observe and compare the influence on the recovery of resting potential of skeletal muscle by taking acupuncture and magnetic needle as the recovery means.DESIGN: A controlled study.SETTINGS: College of Physical Education, Shanxi Normal University;Binzhou College of Shandong Province.MATERIALS: Thirty experimental toads, which were provided by Beijing University of Physical Education, were randomly divided into acupuncture group (n=10), magnetic needle group (n=10), magnetic needle+pressing group (n=10). Left and right semitendinosus muscles were taken as controls.METHODS: The in vitro toad's semitendinosus muscles (experimental side and control side) were treated with electrostimulation for 40 minutes,and then the resting potential of skeletal muscular cells were measured with the intracellular glass microelectrode technique. After the electrostimulation, filiform needle acupuncture, magnetic needle, magnetic needle plus pressing were also given.MAIN OUTCOME MEASURES: The resting potentials were observed before exercise, after electrostimulation and other treatments in the groups.RESULTS: ① The resting potentials of skeletal muscular cells after electrostimulation were decreased as compared with those before electrostimulation [experimental side: (59.48±7.37), (84.54±5.72) mV; control side:(59.43±7.14), (83.62±5.86) mV]. ② After the treatments of acupuncture,magnetic lifting needle, magnetic lifting needle plus pressing, the decreased resting potentials after electrostimulation were obviously recovered (P ＜ 0.01). ③ The recovered percentage of resting potential in the magnetic needle group was obviously smaller than those in the acupuncture group and magnetic needle+pressing group [(42.50±12.41)%, (53.71±10.93)%,(49.10±8.39)%, P ＜ 0. 01].CONCLUSION: Acupuncture, magnetic lifting needle, magnetic lifting needle plus pressing plays a role in promoting the recovery of resting potential of skeletal muscular cells after long-term electrostimulation, and the effect of simple magnetic needle is smaller than that of acupuncture and magnetic needle plus pressing.
