TheInner Canon of Huangdi originated from moral.In the aspect of knowledge, it advocatesthat the doctor should not teach bandits, selecting and teaching, upright character, open but not narrow;In terms of career pursuit, it advocatesthat the doctor should adopt and frequently ask, work hard and to be a good doctor;In the as-pect of ethics, it advocatesthatdoctor should cherish life, be meticulous;In terms of professional belief, it advocat-esthatdoctor should learn from the ancient, firmly believe that science, opposing superstition; TheInner Canon of Huangdi advocate consummate medical skillthe noble medical ethics, with far-reaching influence, become the ori-gin of Chinese medical ethics thought germinal, future generations of today′s high-quality professional talents of Chinese medicine has a very important guiding significance.

Hemorrhagic transformation is a common complication after ischemic stroke, especially after thrombolytic therapy. Its disability and mortality are very high. Therefore, it limits the clinical application of thrombolytic therapy. This article reviews the types of hemorrhagic transformation, possible mechanisms and predictors after thrombolysis for ischemic stroke in order to provide reference for clinical treatment and research of ischemic stroke.

The increasing magnetic strengths used for magnetic resonance imaging (MRI) combined with a greater number of MRI patients with cochlear implants (CIs) raises possible safety issues.This paper reviews the interactions between MRI and CI,and assesses MRI compatibility and safety of CIs at 0.2,0.3,1.0,1.5 and 3.0 tesla (T).In a word,CIs represent a significantcontraindication to MRI.Only after careful evaluation of the individual risk and careful preparations can an MRI be safely performed.

The core values of traditional Chinese medicine culture greatly correlate with the ideological and political education of medical students and they can be integrated.Based on the discussion of the relationship between traditional Chinese medicine culture and medical students' ideological and political education,this paper analyzed the significance of integrating traditional Chinese medicine culture into medical students' ideological and political education:it could help to cultivate college students' patriotic sentiments,sense of honesty,and professional ethics.In addition,it put forward concrete implementation paths:exerting regional advantages and creating characteristic brand of ideological and political education,enriching classroom teaching and innovating the ways of ideological and political education,strengthening cultural construction and strengthening the perceptual cognition of ideological and political education,highlighting typical demonstration and enlarging the positive influence of ideological and political education.

As one subclass of forkhead proteins, the forkhead box O ( FoxO) transcription factors take part in a series of bio-logical processes including cellular apoptosis, damaged DNA re-pair and cleavage of reactive oxygen species(ROS). Increasing evidence highlights that oxidative stress elicited by FoxOs con-tributes to imbalance of redox status in cells related to bone me-tabolism, resulting in development of the pathogenesis of osteo-porosis. This article reviews the relationship of FoxOs and osteo-porosis, which may be beneficial for the research of pathological mechanism and therapeutic strategy of osteoporosis.

OBJECTIVE： To develop a method of thin－ layer chromatographic scanning to determine the content of puerarin in Jiangtang pill METHODS： Silica GF254 thin－ layer was used， and the mobile phase consisted of chloroform－ methanol－ water(7∶ 2 5∶ 0 25) with the detection wave－ length of 254nm and the control wave－ length of 370nm RESULTS： The linear range of puerarin was 0 4～ 2 0μ g The mean recovery was 99 40％ (n=5) with RSD of 1 37％  CONCLUSION： This method is accurate， reliable and can be used for the determination of puerarin in Jiangtang pill

ObjectiveTo investigate relationship between the degree of placenta praevia, vaginal bleeding and clinical outcomes. MethodsRecords of 89 patients with placenta praevia(mild praevia group 43; severe praevia group 46) were reviewed retrospectively, and outcomes were compared. ResultsThe gestational age at the first bleeding and diagnosis was significantly smaller in severe group than that in mild one (P<0.05). The incidence of antepartum haemorrhage, the times of bleeding and the episodes of heavy bleeding in two groups showed no significant differences(P>0.05). The gestational age at diagnosis and delivery and birthweight were significantly smaller in women with antepartum bleeding than in those without( P<0.01 ). The number of deliveries by emergency caesarean section in women with antepartum bleeding was significantly higher than that in those without (P<0.01). ConclusionThe clinical outcomes of placenta praevia are highly variable. There are no obvious clinical features that are typical in predicting the clinical outcomes. The number of bleeding episodes and the degree of praevia are not associated with outcomes, so they can't be the proof to determine the treatment plan ahead of time.

Objective:To probe the effect of prenatal ethanol exposure on the mitochondrial protein expression in fetal mouse cerebrum. Methods:Pregnant CD-1 mice were given 5.0 g/kg ethanol intragastrically from pregnant days (PD) 6-15. Fetal cerebral mitochondria were isolated on PD 18. The overall mitochondrial protein was applied to two-dimensional gel electrophoresis. Differentially expressed protein spots were cut off and identified by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry. Activities of respiratory chain complex Ⅳ(72.3%?4.6% of control)and ATP synthase, and ATP content in the fetal cerebral cells were measured. Results:Expressions of some constructional and functional proteins were altered by in utero ethanol exposure. Activities of respiratory chain complex Ⅳ and ATP synthase (80.3%?5.1% of control)were both decreased. ATP content (67.9%?3.9% of control) in the cerebral cells was reduced in the in utero ethanol exposure fetuses. Conclusion:In utero ethanol exposure affects the mitochondrial protein expression of fetal mouse cerebrum, even in the tissue without obvious morphological malformations, which may be a possible mechanism of behavioral defects found in children with prenatal ethanol exposure.

Objective To investigate the clinical features of primary angiitis of the central nervous system (PACNS). Methods The clinical data of 27 patients with PACNS were analyzed. Results PACNS commonly occured in young and middli-aged adult and with acute or subacute onset. The clinical manifestations were mainly including headache,decrudescence of cortical functions,focal neurological deficits and seizures. The hypointensity signals on T1WI and T2WI were showed and could be enhanced at lesions by skull MRI. The pia vessels inflammatory lesions were revealed in brain by pathological examination. The treated with glucocorticoid and combined therapy such as anti platelet aggregation,scavenging free radicals,reducing intracranial pressure,improving microcirculation and promoting neuronic metabolism,the condition get better.Conclusions The clinical manifestation of PACNS is various. The diagnosis can be make by combining the data of clinical features,imaging and brain biopsy.The treatment with glucocorticoid can obtain better efficacy.

Objective To design and apply ventilator-associated pneumonia prevention checklist in ICU.Methods The ventilator-associated pneumonia prevention checklist was designed by referring to guidelines and related literature.The checklist was applied to ventilator-dependent patients.The head of nursing group evaluated prevention status of ventilator-associated pneumonia performed by nurses every day.Results After application of the checklist,the average indwelling time of tracheal catheter and the incidence of ventilator-associated pneumonia decreased among ICU patients.Conclusion Using the ventilator-associated pneumonia prevention checklist in quality management in the prevention of ventilator-associated pneumonia can shorten the average indwelling time of tracheal catheter,and reduce the incidence of ventilator-associated pneumonia,and the checklist can be promoted and applied.
